What is Radical Behaviorism? A Review of Jay Moore's Conceptual Foundations of Radical Behaviorism

PubMed Central

Baum, William M

2011-01-01

B. F. Skinner founded both radical behaviorism and behavior analysis. His founding innovations included: a versatile preparation for studying behavior; explicating the generic nature of stimulus and response; a pragmatic criterion for defining behavioral units; response rate as a datum; the concept of stimulus control; the concept of verbal behavior; and explicating the explanatory power of contingencies. Besides these achievements, however, Skinner also made some mistakes. Subsequent developments in radical behaviorist thought have attempted to remedy these mistakes. Moore's book presents a “party line” version of radical behaviorism. It focuses narrowly on a few of Skinner's concepts (mostly mentalism and verbal behavior) and contains no criticism of his mistakes. In fact, Moore adds a few mistakes of his own manufacture; for example, he insists that the mental realm does not exist—an unprovable and distracting assertion. The book's portrayal of behavior analysis would have been current around 1960; it mentions almost none of the developments since then. It also includes almost no developments in radical behaviorism since Skinner. Moore's book would give an unwary reader a highly distorted picture of contemporary behavior analysis and radical behaviorism.

The wisdom of deliberate mistakes.

Before the breakup of the Bell System, U.S. telephone companies were permitted by law to ask for security deposits from a small percentage of subscribers. The companies used statistical models to decide which customers were most likely to pay their bills late and thus should be charged a deposit, but no one knew whether the models were right. So the Bell companies made a deliberate mistake. They asked for no deposit from nearly 100,000 new customers randomly selected from among those who were considered high risks. Surprisingly, quite a few paid their bills on time. As a result, the companies instituted a smarter screening strategy, which added millions to the Bell System's bottom line. Usually, individuals and organizations go to great lengths to avoid errors. Companies are designed for optimum performance rather than for learning, and mistakes are seen as defects. But as the Bell System example shows, making mistakes--correctly--is a powerful way to accelerate learning and increase competitiveness. If one of a company's fundamental assumptions is wrong, the firm can achieve success more quickly by deliberately making errors than by considering only data that support the assumption. Moreover, executives who apply a conventional, systematic approach to solving a pattern recognition problem are often slower to find a solution than those who test their assumptions by knowingly making mistakes. How do you distinguish between smart mistakes and dumb ones? The authors' consulting firm has developed, and currently uses, a five-step process for identifying constructive mistakes. In one test, the firm assumed that a mistake it was planning to make would cost a significant amount of money, but the opposite happened. By turning assumptions on their heads, the firm created more than dollar 1 million in new business.

Fatal cardiac glycoside poisoning due to mistaking foxglove for comfrey.

Accidental ingestion of foxglove (Digitalis purpurea) can cause significant cardiac toxicity. We report a patient who ingested foxglove mistaking it for comfrey and developed refractory ventricular arrhythmias. The patient died despite treatment with digoxin-specific antibody fragments (DSFab) and veno-arterial extracorporeal membrane oxygenation (VA-ECMO). A 55-year-old woman presented to the emergency department with nausea, vomiting and generalized weakness eight hours after drinking "comfrey" tea. She had bradycardia (54 beats/min) and hyperkalemia (7.6 mEq/L). Electrocardiogram revealed a first-degree atrioventricular conduction block with premature atrial contractions, followed by polymorphic ventricular tachycardia three hours after arrival. A serum digoxin level was 151.2 ng/mL. The patient developed ventricular fibrillation while waiting for Digibind infusion. Resuscitation was performed and an emergent VA-ECMO was set up. A total of eight vials of Digibind were given over the next 16 hours. She temporarily regained consciousness, but remained hemodynamically unstable and subsequently developed lower limb ischemia and multiple organ failure, and she expired on hospital day seven. A botanist confirmed that the plant was foxglove. The diagnosis of cardiac glycoside plant poisoning can be difficult in the absence of an accurate exposure history. In facilities where DSFab is unavailable or insufficient, early VA-ECMO might be considered in severely cardiotoxic patients unresponsive to conventional therapy.

[Understanding mistake-proofing].

PubMed

de Saint Maurice, G; Giraud, N; Ausset, S; Auroy, Y; Lenoir, B; Amalberti, R

2011-01-01

The mistake-proofing concept often refers to physical devices that prevent actors from making a wrong action. In anaesthesiology, one immediately thinks to specific design of outlets for medical gases. More generally, the principle of mistake-proofing is to avoid an error, by placing knowledge in the world rather than knowledge in the head. As it often happens in risk management, healthcare has received information transfers from the industry. Computer is changing the concept of mistake-proofing, initially based on physical design, such as aerospace and automotive industry. The mistake-proofing concept may be applied to prevention, detection, and mitigation of errors. The forcing functions are a specific part of mistake-proofing: they prevent a wrong action or they force a virtuous one. Grout proposes a little shortcut to identify mistake-proofing devices: "If it is not possible to picture it in action, it is probably not a mistake-proofing device".

Errors related to high-alert medications, such as chemotherapeutic agents, have resulted in serious adverse events. A fast-paced application of Lean Sigma methodology was used to safeguard the chemotherapy preparation process against errors and increase compliance with United States Pharmacopeia 797 (USP 797) regulations. On Days 1 and 2 of a Lean Sigma workshop, frontline staff studied the chemotherapy preparation process. During Days 2 and 3, interventions were developed and implementation was started. The workshop participants were satisfied with the speed at which improvements were put to place using the structured workshop format. The multiple opportunities for error identified related to the chemotherapy preparation process, workspace layout, distractions, increased movement around ventilated hood areas, and variation in medication processing and labeling procedures. Mistake-proofing interventions were then introduced via workspace redesign, process redesign, and development of standard operating procedures for pharmacy staff. Interventions were easy to implement and sustainable. Reported medication errors reaching patients and requiring monitoring decreased, whereas the number of reported near misses increased, suggesting improvement in identifying errors before reaching the patients. Application of Lean Sigma solutions enabled the development of a series of relatively inexpensive and easy to implement mistake-proofing interventions that reduce the likelihood of chemotherapy preparation errors and increase compliance with USP 797 regulations. The findings and interventions are generalizable and can inform mistake-proofing interventions in all types of pharmacies.

The role of indigenous traditional counting systems in children's development of numerical cognition: results from a study in Papua New Guinea

Matang, Rex A. S.; Owens, Kay

2014-09-01

The Government of Papua New Guinea undertook a significant step in developing curriculum reform policy that promoted the use of Indigenous knowledge systems in teaching formal school subjects in any of the country's 800-plus Indigenous languages. The implementation of the Elementary Cultural Mathematics Syllabus is in line with the above curriculum emphasis. Given the aims of the reform, the research reported here investigated the influence of children's own mother tongue (Tok Ples) and traditional counting systems on their development of early number knowledge formally taught in schools. The study involved 272 school children from 22 elementary schools in four provinces. Each child participated in a task-based assessment interview focusing on eight task groups relating to early number knowledge. The results obtained indicate that, on average, children learning their traditional counting systems in their own language spent shorter time and made fewer mistakes in solving each task compared to those taught without Tok Ples (using English and/or the lingua franca, Tok Pisin). Possible reasons accounting for these differences are also discussed.

A few years of experience of teaching mathematics make us notice that the same types of mistakes are done repeatedly by students. This paper presents an insight into categories of mistakes, how male and female students differ in terms of mistakes that are commonly done and the ability of the students to identify the mistakes. Sample of mistakes were taken from Calculus 1 final exam answer scripts, then it was listed and analyzed. Data analysis revealed that students' misconceptions fall into four categories. The first category is misunderstanding the meaning of brackets, followed by misconception of basic mathematics rules, misconception in notation and misconception in properties of trigonometry. A mistake identification test which consists of ten false mathematical statements was designed based on the mistake done by the previous batch of students that covered topics algebra, trigonometry, index, limit, differentiation and integration. Then, the test was given to students who enrolled in Calculus I course. Respondents of this study were randomly selected among two hundreds engineering students. Data obtained were analyzed using basic descriptive analysis and Chi Square test to capture gender differences in the mistake done for each category. Findings indicate that thirty five percent of the students have the ability to identify the mistakes and make a proper correction for at most two statements. Thirty one percent of the students are able to identify the mistakes but unable to make proper correction. Twenty five percent of the students failed to identify the mistakes in six out of ten false statements. Female students' misconception is more likely in basic mathematics rules compared to male. The findings of this study could serve as baseline information to be stressed in improving teaching and learning mathematics.

A Blast of Mistakes: Undiagnosed Cervical Spondylolisthesis Following a Bomb Explosion.

BACKGROUND A case of spinal trauma had an unusual clinical course due to medical mistakes, from which we can learn some important lessons. CASE REPORT We report a case of spondylolisthesis following a bomb explosion, which went undiagnosed for a long time because of a series of mistakes that are highlighted in this article. What makes this case unique is that the spondylolisthesis developed during hospital stay, but the patient had no loss of mobility, strength, or sensitivity. CONCLUSIONS This case shows that establishing the conditions of an organ or a body part upon admission to hospital may not be enough when a patient has suffered extensive and serious trauma, and that it is necessary to carry out more checkups over time, especially if there are new clues and symptoms.

Mistakes in a stat laboratory: types and frequency.

PubMed

Plebani, M; Carraro, P

1997-08-01

Application of Total Quality Management concepts to laboratory testing requires that the total process, including preanalytical and postanalytical phases, be managed so as to reduce or, ideally, eliminate all defects within the process itself. Indeed a "mistake" can be defined as any defect during the entire testing process, from ordering tests to reporting results. We evaluated the frequency and types of mistakes found in the "stat" section of the Department of Laboratory Medicine of the University-Hospital of Padova by monitoring four different departments (internal medicine, nephrology, surgery, and intensive care unit) for 3 months. Among a total of 40490 analyses, we identified 189 laboratory mistakes, a relative frequency of 0.47%. The distribution of mistakes was: preanalytical 68.2%, analytical 13.3%, and postanalytical 18.5%. Most of the laboratory mistakes (74%) did not affect patients' outcome. However, in 37 patients (19%), laboratory mistakes were associated with further inappropriate investigations, thus resulting in an unjustifiable increase in costs. Moreover, in 12 patients (6.4%) laboratory mistakes were associated with inappropriate care or inappropriate modification of therapy. The promotion of quality control and continuous improvement of the total testing process, including pre- and postanalytical phases, seems to be a prerequisite for an effective laboratory service.

Instructional design in mathematics for undergraduate students based on learning by mistakes approach utilizing scilab assistance

Kartika, H.

2018-03-01

The issue related to making mistake while learning such as negative emotion is found while students learn mathematics with the aid of a computer. When the computer output showed a mistake message, the students considered it as a computer software malfunction. Based on this issue, the writer designs an instructional model based on learning by mistake approach and which is Scilab assisted. The method used in this research is research design involving undergraduate students in matrix algebra courses. The data collected throught survey with questionnaire to gain feedback about the approach implemented. The data analyzed using quantitative descriptive. The instructional design proposed is the student act as a mistake corrector while the teacher acts as a mistake maker. Teacher deliberately makes mistakes with the help of Scilab software. On the other hand, students correct, analyze and explain errors resulting from Scilab software. The result of this research is an ICT based instructional design which is expected to be applicable as an alternative learning in directing students to think positively about mistakes in learning. Furthermore, students are also expected to improve their ability in understanding and thinking critically while solving problems and improving themselves in learning mathematics.

Managing medical mistakes: ideology, insularity and accountability among internists-in-training.

PubMed

Mizrahi, T

1984-01-01

By the end of graduate medical training, novice internists (collectively known as the housestaff) were initiated into the experience of either having done something to a patient which had a deleterious consequence or else having witnessed colleagues do the same. When these events occurred, the housestaff engaged in social-psychological processes, utilizing a variety of coping mechanisms and in-group practices to manage these mishaps. Three major mechanisms were utilized by the housestaff for defining and defending the various mishaps which frequently occurred: denial, discounting and distancing. Denial consisted of three components: the negation of the concept of error by defining the practice of medicine as an art with 'gray areas', the repression of actual mistakes by forgetting them and the redefinition of mistakes to non-mistakes. Discounting included those defenses which externalized the blame; namely mistakes which were due to circumstances beyond their control. These included: blaming the bureaucratic system outside of medicine; blaming superiors or subordinates within internal medicine; blaming the disease and blaming the patient. When they could not longer deny or discount a mistake because of its magnitude, they utilized distancing techniques. Not withstanding this shared elaborate repertoire of denial, discounting and distancing, it was found that profound doubts and even guilt remained for many housestaff. These troublesome feelings neither easily nor automatically resolved themselves. Interspersed among their defenses were fundamental questions of culpability and responsibility as they vacillated between self and other blame. For many 'the case was never closed', even as they terminated formal training, a point neglected in the medical and sociological literature. Little in their 3 year graduate program allowed them to work through the attendant vulnerability and ambiguity accompanying the managing of mistakes. Hence, there were maladaptive aspects of the collectively acquired defense mechanisms. The whole system of accountability during graduate medical specialty training was found to be a variable, and at times, contradictory process. The housestaff ultimately sees itself as the sole arbiter of mistakes and their adjudication. Housestaffers come to feel that nobody can judge them or their decisions, least of all their patients. As they progress through training even internal accountability cohorts--the Department of Medicine, teaching faculty and peers--are discounted to varying degrees. They have developed a strong ideology justifying their jealously guarded autonomy.(ABSTRACT TRUNCATED AT 400 WORDS)

Satellite-instrument system engineering best practices and lessons

NASA Astrophysics Data System (ADS)

Schueler, Carl F.

2009-08-01

This paper focuses on system engineering development issues driving satellite remote sensing instrumentation cost and schedule. A key best practice is early assessment of mission and instrumentation requirements priorities driving performance trades among major instrumentation measurements: Radiometry, spatial field of view and image quality, and spectral performance. Key lessons include attention to technology availability and applicability to prioritized requirements, care in applying heritage, approaching fixed-price and cost-plus contracts with appropriate attention to risk, and assessing design options with attention to customer preference as well as design performance, and development cost and schedule. A key element of success either in contract competition or execution is team experience. Perhaps the most crucial aspect of success, however, is thorough requirements analysis and flowdown to specifications driving design performance with sufficient parameter margin to allow for mistakes or oversights - the province of system engineering from design inception to development, test and delivery.

Make no mistake—errors can be controlled*

PubMed Central

Hinckley, C

2003-01-01



 Traditional quality control methods identify "variation" as the enemy. However, the control of variation by itself can never achieve the remarkably low non-conformance rates of world class quality leaders. Because the control of variation does not achieve the highest levels of quality, an inordinate focus on these techniques obscures key quality improvement opportunities and results in unnecessary pain and suffering for patients, and embarrassment, litigation, and loss of revenue for healthcare providers. Recent experience has shown that mistakes are the most common cause of problems in health care as well as in other industrial environments. Excessive product and process complexity contributes to both excessive variation and unnecessary mistakes. The best methods for controlling variation, mistakes, and complexity are each a form of mistake proofing. Using these mistake proofing techniques, virtually every mistake and non-conformance can be controlled at a fraction of the cost of traditional quality control methods. PMID:14532368

Evaluation of gap filling skills and reading mistakes of cochlear implanted and normally hearing students.

2018-06-01

This study aimed to (1) evaluate the gap filling skills and reading mistakes of students with cochlear implants, and to (2) compare their results with those of their normal-hearing peers. The effects of implantation age and total time of cochlear implant use were analyzed in relation to the subjects' reading skills development. The study included 19 students who underwent cochlear implantation and 20 students with normal hearing, who were enrolled at the 6th to 8th grades. The subjects' ages ranged between 12 and 14 years old. Their reading skills were evaluated by using the Informal Reading Inventory. A significant relationship were found between implanted and normal-hearing students in terms of the percentages of reading error and the percentages of gap filling scores. The average order of the reading errors of students using cochlear implants was higher than that of normal-hearing students. As for the gap filling, the performances of implanted students in the passage are lower than those of their normal-hearing peers. No significant relationship was found between the variables tested in terms of age and duration of implantation on the reading performances of implanted students. Even if they were early implanted, there were significant differences in the reading performances of implanted students compared with those of their normal-hearing peers in older classes.

Marine EM: The Past, The Present, and The Future

NASA Astrophysics Data System (ADS)

Constable, S.

2016-12-01

The high cost of deepwater exploration motivated the development of commercial marine magnetotelluric (MT) exploration in 1995, but it wasn't until marine controlled-source electromagnetic (CSEM) methods burst upon the industry scene with the formation of three new contractors in 2002 that things got really exciting. Now the bubble has burst and the excitement has diminished, but marine EM remains an important tool for offshore exploration. Early mistakes were made as a result of poor instrumentation and a lack of good interpretation tools - unlike seismics, EM relies heavily on inversion to produce useful results - but both equipment and inversion codes have improved significantly. Still, there are mistakes that can be made. Rock anisotropy and seawater conductivity have to be handled appropriately. A strong galvanic response means that there is a resistivity/thickness ambiguity when imaging reservoirs, but the inductive nature of the data means that multi-frequency inversions are very much better than using single frequencies. Resolution will never be as good as for seismic methods, but is much better than for potential field methods and conductivity may often be a more diagnostic property than acoustic impedance. EM images resistivity, not hydrocarbon content, and false positives occasionally occur, but false negatives are rare. That is, without a CSEM signature there is little chance of discovering economical hydrocarbons. This should bode well for the future of the method.

The occurrence of overrun in cost and time in a project that is usually caused by contractors, will generally make peopleput the blameonthem. This happensas a result of the lack of knowledge possessed by the contractors in determining the solution to be undertakendue totheir mistakes, especially when it comes to tendering process as what had happened in the cases that were reported in Supreme Court of Canada. This paper aims to identify the types of mistakes, factors that contribute to the mistakes and the responsiveness to the mistakes so that the contractor will be able to manage and control the mistakes, as well as the solution, along with preventing them from happening, and in making decision whether or notthey may withdraw from the bidding when the fault has been discovered or whether they should request for leniency from the client for a second chance in re-submitting the bid after the discovered inaccuracy. This research has been done based on cases that were related to the contractor’s mistakes during tendering which were collected from the Supreme Courts of Canada. The data have been analysed and interpreted by legal methodology, in which the result shows that the ability level of the contractors to respond to the mistake is unsatisfactory,and the fault is continuouslybeingmade. The findings are expected to educate and provide awareness to the contractors relating to the matters discussed.

Improving the patient, family, and clinician experience after harmful events: the "when things go wrong" curriculum.

PubMed

Bell, Sigall K; Moorman, Donald W; Delbanco, Tom

2010-06-01

The emotional toll of medical error is high for both patients and clinicians, who are often unsure with whom-and whether-they can discuss what happened. Although institutions are increasingly adopting full disclosure policies, trainees frequently do not disclose mistakes, and faculty physicians are underprepared to teach communication skills related to disclosure and apology. The authors developed an interactive educational program for trainees and faculty physicians that assesses experiences, attitudes, and perceptions about error, explores the human impact of error through filmed patient and family narratives, develops communication skills, and offers a strategy to facilitate bedside disclosures. Between spring 2007 and fall 2008, 154 trainees (medical students/residents) and 75 medical educators completed the program. Among learners surveyed, 62% of trainees and 88% of faculty physicians reported making medical mistakes. Of those, 62% and 78%, respectively, reported they did not apologize. While 65% of trainees said they would turn to senior doctors for assistance after an error, 26% were not sure where to get help. Just 20% of trainees and 21% of physicians reported adequate training to respond to error. Following the session, all of the faculty physicians surveyed indicated they felt better prepared to address and teach this topic. At a time of increased attention to disclosure, actual faculty and trainee practices suggest that role models, support systems, and education strategies are lacking. Trainees' widespread experience with error highlights the need for a disclosure curriculum early in medical education. Educational initiatives focusing on communication after harm should target teachers and students.

Overcoming barriers to electronic medical record (EMR) implementation in the US healthcare system: A comparative study.

2010-12-01

An EMR system implementation would significantly reduce clinician workload and medical errors while saving the US healthcare system major expense. Yet, compared to other developed nations, the US lags behind. This article examines EMR system efforts, benefits, and barriers, as well as steps needed to move the US closer to a nationwide EMR system. The analysis includes a blueprint for implementation of EMR, industry comparisons to highlight the differences between successful and non-successful EMR ventures, references to costs and benefit information, and identification of root causes. 'Poka-yokes' (avoid (yokeru) mistakes (poka)) will be inserted to provide insight into how to systematically overcome challenges. Implementation will require upfront costs including patient privacy that must be addressed early in the development process. Government structure, incentives and mandates are required for nationwide EMR system in the US.

No methodologically robust system exists for capturing consumer-generated patient safety reports. To address this challenge, we developed and pilot-tested a prototype consumer reporting system for patient safety, the Health Care Safety Hotline. Mixed methods evaluation. The Hotline was implemented in two US healthcare systems from 1 February 2014 through 30 June 2015. Patients, family members and caregivers associated with two US healthcare systems. A consumer-oriented incident reporting system for telephone or web-based administration was developed to elicit medical mistakes and care-related injuries. Key informant interviews, measurement of website traffic and analysis of completed reports. Key informants indicated that Hotline participation was motivated by senior leaders' support and alignment with existing quality and safety initiatives. During the measurement period from 1 October 2014 through 30 June 2015, the home page had 1530 visitors with a unique IP address. During its 17 months of operation, the Hotline received 37 completed reports including 20 mistakes without harm and 15 mistakes with injury. The largest category of mistake concerned problems with diagnosis or advice from a health practitioner. Hotline reports prompted quality reviews, an education intervention, and patient follow-ups. While generating fewer reports than its capacity to manage, the Health Care Safety Hotline demonstrated the feasibility of consumer-oriented patient safety reporting. Further research is needed to understand how to increase consumers' use of these systems. © The Author 2017.

Payoff non-linearity sways the effect of mistakes on the evolution of reciprocity.

PubMed

Kurokawa, Shun

2016-09-01

The existence of cooperation is considered to require explanation, and reciprocity is a potential explanatory mechanism. Animals sometimes fail to cooperate even when they attempt to do so, and a reciprocator has an Achilles' heel: it is vulnerable to error (the interaction between two reciprocators can lead to an endless vendetta.). However, the strategy favored by natural selection is determined also by its interaction with other strategies. The relationship between two reciprocators leading to a collapse of cooperation through error does not straightforwardly imply that mistakes make the conditions under which reciprocity evolves stringent. Hence, mistakes may facilitate the evolution of reciprocity. However, it has been shown through the analysis of the interaction between reciprocators and unconditional defectors that the existence of mistakes makes the conditions for reciprocators stable against invasion by an unconditional defector more stringent, which indicates that mistakes discourage the evolution of reciprocity. However, this result is based on the assumption that the effects of cooperation are additive (payoff is linear), while the game played by real animals does not always display this feature. In such cases, the result may be swayed. In this paper, we remove this assumption, reexamining whether mistakes disturb the evolution of reciprocity. Using the analysis of an evolutionarily stable strategy (ESS), we show that when extra fitness costs are present in cases where mutual cooperation is established, mistakes can facilitate the evolution of reciprocity; whereas, when the effect of cooperation is additive, mistakes always disturb the evolution of reciprocity, as has been shown previously.

Defining the best quality-control systems by design and inspection.

PubMed

Hinckley, C M

1997-05-01

Not all of the many approaches to quality control are equally effective. Nonconformities in laboratory testing are caused basically by excessive process variation and mistakes. Statistical quality control can effectively control process variation, but it cannot detect or prevent most mistakes. Because mistakes or blunders are frequently the dominant source of nonconformities, we conclude that statistical quality control by itself is not effective. I explore the 100% inspection methods essential for controlling mistakes. Unlike the inspection techniques that Deming described as ineffective, the new "source" inspection methods can detect mistakes and enable corrections before nonconformities are generated, achieving the highest degree of quality at a fraction of the cost of traditional methods. Key relationships between task complexity and nonconformity rates are also described, along with cultural changes that are essential for implementing the best quality-control practices.

The neural basis of financial risk taking.

PubMed

Kuhnen, Camelia M; Knutson, Brian

2005-09-01

Investors systematically deviate from rationality when making financial decisions, yet the mechanisms responsible for these deviations have not been identified. Using event-related fMRI, we examined whether anticipatory neural activity would predict optimal and suboptimal choices in a financial decision-making task. We characterized two types of deviations from the optimal investment strategy of a rational risk-neutral agent as risk-seeking mistakes and risk-aversion mistakes. Nucleus accumbens activation preceded risky choices as well as risk-seeking mistakes, while anterior insula activation preceded riskless choices as well as risk-aversion mistakes. These findings suggest that distinct neural circuits linked to anticipatory affect promote different types of financial choices and indicate that excessive activation of these circuits may lead to investing mistakes. Thus, consideration of anticipatory neural mechanisms may add predictive power to the rational actor model of economic decision making.

Mistake proofing: changing designs to reduce error

PubMed Central

Grout, J R

2006-01-01

Mistake proofing uses changes in the physical design of processes to reduce human error. It can be used to change designs in ways that prevent errors from occurring, to detect errors after they occur but before harm occurs, to allow processes to fail safely, or to alter the work environment to reduce the chance of errors. Effective mistake proofing design changes should initially be effective in reducing harm, be inexpensive, and easily implemented. Over time these design changes should make life easier and speed up the process. Ideally, the design changes should increase patients' and visitors' understanding of the process. These designs should themselves be mistake proofed and follow the good design practices of other disciplines. PMID:17142609

Unexpected Results are Usually Wrong, but Often Interesting

NASA Astrophysics Data System (ADS)

Huber, M.

2014-12-01

In climate modeling, an unexpected result is usually wrong, arising from some sort of mistake. Despite the fact that we all bemoan uncertainty in climate, the field is underlain by a robust, successful body of theory and any properly conducted modeling experiment is posed and conducted within that context. Consequently, if results from a complex climate model disagree with theory or from expectations from simpler models, much skepticism is in order. But, this exposes the fundamental tension of using complex, sophisticated models. If simple models and theory were perfect there would be no reason for complex models--the entire point of sophisticated models is to see if unexpected phenomena arise as emergent properties of the system. In this talk, I will step through some paleoclimate examples, drawn from my own work, of unexpected results that emerge from complex climate models arising from mistakes of two kinds. The first kind of mistake, is what I call a 'smart mistake'; it is an intentional incorporation of assumptions, boundary conditions, or physics that is in violation of theoretical or observational constraints. The second mistake, a 'dumb mistake', is just that, an unintentional violation. Analysis of such mistaken simulations provides some potentially novel and certainly interesting insights into what is possible and right in paleoclimate modeling by forcing the reexamination of well-held assumptions and theories.

2017-09-01

In recent years, adsorption science and technology for water and wastewater treatment has attracted substantial attention from the scientific community. However, the number of publications containing inconsistent concepts is increasing. Many publications either reiterate previously discussed mistakes or create new mistakes. The inconsistencies are reflected by the increasing publication of certain types of article in this field, including "short communications", "discussions", "critical reviews", "comments", "letters to the editor", and "correspondence (comment/rebuttal)". This article aims to discuss (1) the inaccurate use of technical terms, (2) the problem associated with quantities for measuring adsorption performance, (3) the important roles of the adsorbate and adsorbent pK a , (4) mistakes related to the study of adsorption kinetics, isotherms, and thermodynamics, (5) several problems related to adsorption mechanisms, (6) inconsistent data points in experimental data and model fitting, (7) mistakes in measuring the specific surface area of an adsorbent, and (8) other mistakes found in the literature. Furthermore, correct expressions and original citations of the relevant models (i.e., adsorption kinetics and isotherms) are provided. The authors hope that this work will be helpful for readers, researchers, reviewers, and editors who are interested in the field of adsorption studies. Copyright © 2017 Elsevier Ltd.

Imperfect information facilitates the evolution of reciprocity.

PubMed

Kurokawa, Shun

2016-06-01

The existence of cooperation demands explanation since cooperation is costly to the actor. Reciprocity has long been regarded as a potential explanatory mechanism for the existence of cooperation. Reciprocity is a mechanism wherein a cooperator responds to an opponent's behavior by switching his/her own behavior. Hence, a possible problematic case relevant to the theory of reciprocity evolution arises when the mechanism is such that the information regarding an opponent's behavior is imperfect. Although it has been confirmed also by previous theoretical studies that imperfect information interferes with the evolution of reciprocity, this argument is based on the assumption that there are no mistakes in behavior. And, a previous study presumed that it might be expected that when such mistakes occur, reciprocity can more readily evolve in the case of imperfect information than in the case of perfect information. The reason why the previous study considers so is that in the former case, reciprocators can miss defections incurred by other reciprocators' mistakes due to imperfect information, allowing cooperation to persist when such reciprocators meet. However, contrary to this expectation, the previous study has shown that even when mistakes occur, imperfect information interferes with the evolution of reciprocity. Nevertheless, the previous study assumed that payoffs are linear (i.e., that the effect of behavior is additive and there are no synergetic effects). In this study, we revisited the same problem but removed the assumption that payoffs are linear. We used evolutionarily stable strategy analysis to compare the condition for reciprocity to evolve when mistakes occur and information is imperfect with the condition for reciprocity to evolve when mistakes occur and information is perfect. Our study revealed that when payoffs are not linear, imperfect information can facilitate the evolution of reciprocity when mistakes occur; while when payoffs are linear, imperfect information disturbs the evolution of reciprocity even when mistakes occur. Imperfect information can encourage the evolution of cooperation. Copyright © 2016 Elsevier Inc. All rights reserved.

Six Common Mistakes in Conservation Priority Setting

PubMed Central

Game, Edward T; Kareiva, Peter; Possingham, Hugh P

2013-01-01

Abstract A vast number of prioritization schemes have been developed to help conservation navigate tough decisions about the allocation of finite resources. However, the application of quantitative approaches to setting priorities in conservation frequently includes mistakes that can undermine their authors’ intention to be more rigorous and scientific in the way priorities are established and resources allocated. Drawing on well-established principles of decision science, we highlight 6 mistakes commonly associated with setting priorities for conservation: not acknowledging conservation plans are prioritizations; trying to solve an ill-defined problem; not prioritizing actions; arbitrariness; hidden value judgments; and not acknowledging risk of failure. We explain these mistakes and offer a path to help conservation planners avoid making the same mistakes in future prioritizations. Seis Errores Comunes en la Definición de Prioridades de Conservación Resumen Se ha desarrollado un vasto número de esquemas de priorización para ayudar a que la conservación navegue entre decisiones difíciles en cuanto a la asignación de recursos finitos. Sin embargo, la aplicación de métodos cuantitativos para la definición de prioridades en la conservación frecuentemente incluye errores que pueden socavar la intención de sus autores de ser más rigurosos y científicos en la manera en que se establecen las prioridades y se asignan los recursos. Con base en los bien establecidos principios de la ciencia de la decisión, resaltamos seis errores comúnmente asociados con la definición de prioridades para la conservación: no reconocer que los planes de conservación son priorizaciones; tratar de resolver un problema mal definido; no priorizar acciones; arbitrariedad; juicios de valor ocultos y no reconocer el riesgo de fracasar. Explicamos estos errores y ofrecemos un camino para que planificadores de la conservación no cometan los mismos errores en priorizaciones futuras. PMID:23565990

Looking for evidence that personal hygiene precautions prevent traveler's diarrhea.

Shlim, David R

2005-12-01

In the 50 years during which traveler's diarrhea has been studied, it has always been assumed that personal hygiene precautions can prevent or reduce the likelihood of developing traveler's diarrhea. However, 7 of 8 studies that specifically addressed this issue showed no correlation between the types of food selected and the risk of acquiring traveler's diarrhea. The eighth study showed a correlation between a few dietary mistakes and a decreased risk of acquiring traveler's diarrhea. A further increase in the number of dietary mistakes, however, did not continue to increase the risk of acquiring traveler's diarrhea. Personal hygiene precautions, when performed under the direct supervision of an expatriate operating his or her own kitchen, can prevent traveler's diarrhea, but poor restaurant hygiene in most developing countries continues to create an insurmountable risk of acquiring traveler's diarrhea.

The development of a new safety culture in orthopaedics and trauma surgery needs to be based on the knowledge of the status quo. The objective of this research was therefore to perform a survey of orthopaedic and trauma surgeons to achieve a subjective assessment of the frequency and causes of "insecurities" or errors in daily practice. Based on current literature, an online questionnaire was created by a team of experts (26 questions total) and was sent via e-mail to all active members of a medical society (DGOU) in April 2015. This was followed by two reminder e-mails. The survey was completed in May 2015. The results were transmitted electronically, anonymously and voluntarily into a database and evaluated by univariate analyses. 799 active members took part in the survey. 65% of the interviewed people stated that they noticed mistakes in their own clinical work environment at least once a week. The main reasons for these mistakes were "time pressure", "lack of communication", "lack of staff" and "stress". Technical mistakes or lack of knowledge were not of primary importance. The survey indicated that errors in orthopaedics and trauma surgery are observed regularly. "Human factors" were regarded as a major cause. In order to develop a new safety culture in orthopaedics and trauma surgery, new approaches must focus on the human factor. Georg Thieme Verlag KG Stuttgart · New York.

Unsafe acts and unsafe outcomes in aircraft maintenance

NASA Technical Reports Server (NTRS)

Hobbs, Alan; Williamson, Ann

2002-01-01

Road safety studies using the Driver Behaviour Questionnaire (DBQ) have provided support for a three-way distinction between violations, skill-based errors and mistakes, and have indicated that a tendency to commit driving violations is associated with an increased risk of accident involvement. The aims of this study were to examine whether the three-way distinction of unsafe acts is applicable in the context of aircraft maintenance, and whether involvement in maintenance safety occurrences can be predicted on the basis of self-reported unsafe acts. A Maintenance Behaviour Questionnaire (MBQ) was developed to explore patterns of unsafe acts committed by aircraft maintenance mechanics. The MBQ was completed anonymously by over 1300 Australian aviation mechanics, who also provided information on their involvement in workplace accidents and incidents. Four factors were identified: routine violations, skill-based errors, mistakes and exceptional violations. Violations and mistakes were related significantly to the occurrence of incidents that jeopardized the quality of aircraft maintenance, but were not related to workplace injuries. Skill-based errors, while not related to work quality incidents, were related to workplace injuries. The results are consistent with the three-way typology of unsafe acts described by Reason et al. (1990) and with the DBQ research indicating an association between self-reported violations and accidents. The current findings suggest that interventions addressed at maintenance quality incidents should take into account the role of violations and mistakes, and the factors that promote them. In contrast, interventions directed at reducing workplace injury are likely to require a focus on skill-based errors.

Background: Today, healthy organizations such as hospital have found out the importance of quality of work life (QWL) of their personnel. QWL direct to increase job satisfaction, improve the quality of services to patient of hospital, and create high performance. One of factors that impact QWL is mistake management culture (MMC) when contribute different organization aspects such as QWL and cover its needs and finally promote job performance. Material and Method: A questionnarie was designed with items involve five-item Likert-type scale items and it distribute samong a sample of 207 nurses of four hospitals that voluntarily participated in research plan in Mashhad city. Two hospitals were private and two hospitals were public. Result: There are significant relationships between MMC, QWL and performance. Conclusion: According to importance of enhancement of QWL and job performance in organizations such as hospital, broadcasting culture of mistake management plays positive role and promotes quality level of work life of employees. Therefore, we can improve job satisfaction by changing and manipulating QWL factors, and thus move toward the development of the organization. PMID:23634407

Among papers stating a position on anthropogenic global warming (AGW), 97 % endorse AGW. What is happening with the 2 % of papers that reject AGW? We examine a selection of papers rejecting AGW. An analytical tool has been developed to replicate and test the results and methods used in these studies; our replication reveals a number of methodological flaws, and a pattern of common mistakes emerges that is not visible when looking at single isolated cases. Thus, real-life scientific disputes in some cases can be resolved, and we can learn from mistakes. A common denominator seems to be missing contextual information or ignoring information that does not fit the conclusions, be it other relevant work or related geophysical data. In many cases, shortcomings are due to insufficient model evaluation, leading to results that are not universally valid but rather are an artifact of a particular experimental setup. Other typical weaknesses include false dichotomies, inappropriate statistical methods, or basing conclusions on misconceived or incomplete physics. We also argue that science is never settled and that both mainstream and contrarian papers must be subject to sustained scrutiny. The merit of replication is highlighted and we discuss how the quality of the scientific literature may benefit from replication.

In this essay, I discuss the origin of Charles Darwin's interest in cirripedes (barnacles). Indeed, he worked intensively on cirripedes during the years in which he was developing the theory that eventually led to the publication of The Origin of Species. In the light of our present knowledge, I present Darwin's achievements in the morphology, systematics and biology of these small marine invertebrates, and also his mistakes. I suggest that the word that sheds the most light here is homology, and that his mistakes were due to following Richard Owen's method of determining homologies by reference to an ideal archetype.

A rational analysis of human error leads through the consideration of mistakes to standards that designers use to avoid mistakes that lead to known breakdowns. The irrational side, however, is more interesting. It conditions people to think that breakdowns are inherently wrong and that there is ultimately someone who is responsible. This leads to a search for someone to blame which diverts attention from: learning from the mistakes; seeing the limitations of current engineering methodology; and improving the discourse of design.

Medical knowledge and skills essential for tomorrow's healthcare professionals continue to change faster than ever before creating new demands in medical education. Project TOUCH (Telehealth Outreach for Unified Community Health) has been developing methods to enhance learning by coupling innovations in medical education with advanced technology in high performance computing and next generation Internet2 embedded in virtual reality environments (VRE), artificial intelligence and experiential active learning. Simulations have been used in education and training to allow learners to make mistakes safely in lieu of real-life situations, learn from those mistakes and ultimately improve performance by subsequent avoidance of those mistakes. Distributed virtual interactive environments are used over distance to enable learning and participation in dynamic, problem-based, clinical, artificial intelligence rules-based, virtual simulations. The virtual reality patient is programmed to dynamically change over time and respond to the manipulations by the learner. Participants are fully immersed within the VRE platform using a head-mounted display and tracker system. Navigation, locomotion and handling of objects are accomplished using a joy-wand. Distribution is managed via the Internet2 Access Grid using point-to-point or multi-casting connectivity through which the participants can interact. Medical students in Hawaii and New Mexico (NM) participated collaboratively in problem solving and managing of a simulated patient with a closed head injury in VRE; dividing tasks, handing off objects, and functioning as a team. Students stated that opportunities to make mistakes and repeat actions in the VRE were extremely helpful in learning specific principles. VRE created higher performance expectations and some anxiety among VRE users. VRE orientation was adequate but students needed time to adapt and practice in order to improve efficiency. This was also demonstrated successfully between Western Australia and UNM. We successfully demonstrated the ability to fully immerse participants in a distributed virtual environment independent of distance for collaborative team interaction in medical simulation designed for education and training. The ability to make mistakes in a safe environment is well received by students and has a positive impact on their understanding, as well as memory of the principles involved in correcting those mistakes. Bringing people together as virtual teams for interactive experiential learning and collaborative training, independent of distance, provides a platform for distributed "just-in-time" training, performance assessment and credentialing. Further validation is necessary to determine the potential value of the distributed VRE in knowledge transfer, improved future performance and should entail training participants to competence in using these tools.

Self-Compassion and Relationship Maintenance: The Moderating Roles of Conscientiousness and Gender

PubMed Central

Baker, Levi; McNulty, James K.

2010-01-01

Should intimates respond to their interpersonal mistakes with self-criticism or with self-compassion? Although it is reasonable to expect self-compassion to benefit relationships by promoting self-esteem, it is also reasonable to expect self-compassion to hurt relationships by removing intimates’ motivation to correct their interpersonal mistakes. Two correlational studies, 1 experiment, and 1 longitudinal study demonstrated that whether self-compassion helps or hurts relationships depends on the presence versus absence of dispositional sources of the motivation to correct interpersonal mistakes. Among men, the implications of self-compassion were moderated by conscientiousness. Among men high in conscientiousness, self-compassion was associated with greater motivation to correct interpersonal mistakes (Studies 1 and 3), observations of more-constructive problem-solving behaviors (Study 2), reports of more accommodation (Study 3), and fewer declines in marital satisfaction that were mediated by decreases in interpersonal problem severity (Study 4); among men low in conscientiousness, self-compassion was associated with these outcomes in the opposite direction. Among women, in contrast, likely because women are inherently more motivated than men to preserve their relationships for cultural and/or biological reasons, self-compassion was never harmful to the relationship. Instead, women’s self-compassion was positively associated with the motivation to correct their interpersonal mistakes (Study 1) and changes in relationship satisfaction (Study 4), regardless of conscientiousness. Accordingly, theoretical descriptions of the implications of self-promoting thoughts for relationships may be most complete to the extent that they consider the presence versus absence of other sources of the motivation to correct interpersonal mistakes.

The ability of dental technician students to match tooth shade with the Vita 3D-Master shade guide and Toothguide Training Box has not been investigated. The purpose of this study was to evaluate and compare the shade-matching ability of dental technician students and graduate dentists using the Vita 3D-Master shade guide. Twenty-nine dental technician students (DTS group) and 30 graduate dentists (GD group) participated in this study. The Toothguide Training Box (TTB) was used to train the participants and test their shade-matching abilities. Shade-matching ability was evaluated with 3 exercises and a final test, all of which are components of the TTB. The number of mistakes for each participant for value (L), chroma (c), and hue (h) were recorded during the exercises and the final test, and the mistake ratios were calculated. Color difference (ΔE) values for each shade were calculated from the L*, a*, and b* values of the Vita 3D-Master shade guide for each participant in both groups. The Mann-Whitney U test was used to determine statistically significant differences between the L, c, and h mistake ratios of the 2 groups, and the Student t test was used to determine statistically significant differences between the final test scores and the ΔE values of the groups (α=.05). The mistake ratio for L in the GD group was significantly higher than that of the DTS group (P<.05), whereas the mistake ratio for h in the DTS group was higher (P<.001). No significant differences were observed between the groups regarding the mistake ratios for c (P>.05). With regard to the final test scores and the ΔE values, no significant differences were found between the groups (P<.001), and the DTS group received higher scores than the GD group (912 and 851). The mean ΔE values for the DTS and GD groups were 1.72 and 2.92. DTSs made more mistakes in the h parameter than GDs, and GDs made more mistakes in the L parameter than DTSs. With regard to the final test scores and the ΔE values, DTSs were more successful in shade matching than GDs. Copyright © 2014 Editorial Council for the Journal of Prosthetic Dentistry.

A simple attention test in the acute phase of a major depressive episode is predictive of later functional remission.

PubMed

Cléry-Melin, Marie-Laure; Gorwood, Philip

2017-02-01

Functional recovery after a major depressive episode (MDE) requires both clinical remission and preservation of cognitive skills. As attentional deficit may persist after remission, leading to functional impairment, its role as a prognosis marker needs to be considered. Five hundred eight depressed outpatients (DSM-IV) were assessed at baseline for clinical symptoms (QIDS-SR), social functioning (Sheehan Disability Scale, SDS) and attention through the d2 test of attention and the trail making test, simple tests, respectively, requiring to quote or to interconnect relevant items. All patients were treated by agomelatine, and examined 6 to 8 weeks after baseline to assess clinical remission (QIDS-SR ≤ 5) and/or functional remission (SDS ≤ 6). At follow up, 154 patients (31%) were in clinical and functional remission. Shorter cumulative duration of prior depression, shorter present MDE, and two parameters of the d2 test of attention were predictive of such positive outcome, the number of omission mistakes (F1) being the only one still significantly predictive (P < .05) with a multivariate approach. F1 was unchanged after remission, patients with less than 11 mistakes had a 2.27 times increased chance to reach full remission, and a dose-response relationship was observed, with a regular increase of positive outcome for less mistakes. The number of omission mistakes (F1) of the d2 test of attention was a stable marker, being predictive of, and with a dose-effect for, clinical plus functional remission. It may constitute a specific marker of attentional deficit, involved in the resilience process that enables individuals to develop more adequate strategies to cope with everyday functional activities. © 2016 Wiley Periodicals, Inc.

Category mistakes: A barrier to effective environmental management.

PubMed

Wallace, Ken J; Jago, Mark

2017-09-01

How entities, the things that exist, are defined and categorised affects all aspects of environmental management including technical descriptions, quantitative analyses, participatory processes, planning, and decisions. Consequently, ambiguous definitions and wrongly assigning entities to categories, referred to as category mistakes, are barriers to effective management. Confusion caused by treating the term 'biodiversity' variously as the property of an area, the biota of an area, and a preferred end state (a value) - quite different categories of entities - is one example. To overcome such difficulties, we develop and define four entity categories - elements, processes, properties, and values - and two derived categories - states and systems. We argue that adoption of these categories and definitions will significantly improve environmental communication and analysis, and thus strengthen planning and decision-making.

It has been created a proper device to be used in determining liquid refractive index.

Minimising human error in malaria rapid diagnosis: clarity of written instructions and health worker performance.

The usefulness of rapid diagnostic tests (RDT) in malaria case management depends on the accuracy of the diagnoses they provide. Despite their apparent simplicity, previous studies indicate that RDT accuracy is highly user-dependent. As malaria RDTs will frequently be used in remote areas with little supervision or support, minimising mistakes is crucial. This paper describes the development of new instructions (job aids) to improve health worker performance, based on observations of common errors made by remote health workers and villagers in preparing and interpreting RDTs, in the Philippines and Laos. Initial preparation using the instructions provided by the manufacturer was poor, but improved significantly with the job aids (e.g. correct use both of the dipstick and cassette increased in the Philippines by 17%). However, mistakes in preparation remained commonplace, especially for dipstick RDTs, as did mistakes in interpretation of results. A short orientation on correct use and interpretation further improved accuracy, from 70% to 80%. The results indicate that apparently simple diagnostic tests can be poorly performed and interpreted, but provision of clear, simple instructions can reduce these errors. Preparation of appropriate instructions and training as well as monitoring of user behaviour are an essential part of rapid test implementation.

Error-Monitoring in Response to Social Stimuli in Individuals with Higher-Functioning Autism Spectrum Disorder

PubMed Central

McMahon, Camilla M.; Henderson, Heather A.

2014-01-01

Error-monitoring, or the ability to recognize one's mistakes and implement behavioral changes to prevent further mistakes, may be impaired in individuals with Autism Spectrum Disorder (ASD). Children and adolescents (ages 9-19) with ASD (n = 42) and typical development (n = 42) completed two face processing tasks that required discrimination of either the gender or affect of standardized face stimuli. Post-error slowing and the difference in Error-Related Negativity amplitude between correct and incorrect responses (ERNdiff) were used to index error-monitoring ability. Overall, ERNdiff increased with age. On the Gender Task, individuals with ASD had a smaller ERNdiff than individuals with typical development; however, on the Affect Task, there were no significant diagnostic group differences on ERNdiff. Individuals with ASD may have ERN amplitudes similar to those observed in individuals with typical development in more social contexts compared to less social contexts due to greater consequences for errors, more effortful processing, and/or reduced processing efficiency in these contexts. Across all participants, more post-error slowing on the Affect Task was associated with better social cognitive skills. PMID:25066088

Social Appearance Anxiety and Dietary Restraint as Mediators between Perfectionism and Binge Eating: A Six Month Three Wave Longitudinal Study

PubMed Central

Brosof, Leigh C.; Levinson, Cheri A.

2016-01-01

Binge eating is related to perfectionism and restrained eating. However, the mechanisms underlying these relationships are not well understood. It is possible that social anxiety, specifically social appearance anxiety (i.e., the fear of overall appearance evaluation), influences the relationship between binge eating, perfectionism, and dietary restraint. In the current study (N = 300 women), we tested the relationship between dietary restraint, social appearance anxiety, concern over mistakes (a component of perfectionism), and binge eating in prospective data (three time points: at baseline, at two month, and at six month follow up). We found that social appearance anxiety, dietary restraint, and concern over mistakes each predicted binge eating at baseline. Only social appearance anxiety prospectively predicted binge eating when accounting for all variables. Further, in the tested model, social appearance anxiety mediated the relationship between concern over mistakes and binge eating across six months. On the contrary, dietary restraint did not mediate the relationship between concern over mistakes and binge eating in the tested model. The finding that social appearance anxiety served as a mediator between concern over mistakes and binge eating, but that dietary restraint did not, implies that social appearance anxiety may be a more salient prospective predictor of binge eating than dietary restraint. Intervening on social appearance anxiety may be important in the treatment and prevention of binge eating. PMID:27742237

Surgical errors and risks – the head and neck cancer patient

Head and neck surgery is one of the basic principles of head and neck cancer therapy. Surgical errors and malpractice can have fatal consequences for the treated patients. It can lead to functional impairment and has impact in future chances for disease related survival. There are many risks for head and neck surgeons that can cause errors and malpractice. To avoid surgical mistakes, thorough preoperative management of patients is mandatory. As there are ensuring operability, cautious evaluation of preoperative diagnostics and operative planning. Moreover knowledge of anatomical structures of the head and neck, of the medical studies and data as well as qualification in modern surgical techniques and the surgeons ability for critical self assessment are basic and important prerequisites for head and neck surgeons in order to make out risks and to prevent from mistakes. Additionally it is important to have profound knowledge in nutrition management of cancer patients, wound healing and to realize and to be able to deal with complications, when they occur. Despite all precaution and surgical care, errors and mistakes cannot always be avoided. For that it is important to be able to deal with mistakes and to establish an appropriate and clear communication and management for such events. The manuscript comments on recognition and prevention of risks and mistakes in the preoperative, operative and postoperative phase of head and neck cancer surgery. PMID:24403972

A new look at low-energy nuclear reaction research.

PubMed

Krivit, Steven B; Marwan, Jan

2009-10-01

This paper presents a new look at low-energy nuclear reaction research, a field that has developed from one of the most controversial subjects in science, "cold fusion." Early in the history of this controversy, beginning in 1989, a strong polarity existed; many scientists fiercely defended the claim of new physical effects as well as a new process in which like-charged atomic nuclei overcome the Coulomb barrier at normal temperatures and pressures. Many other scientists considered the entire collection of physical observations-along with the hypothesis of a "cold fusion"--entirely a mistake. Twenty years later, some people who had dismissed the field in its entirety are considering the validity of at least some of the reported experimental phenomena. As well, some researchers in the field are wondering whether the underlying phenomena may be not a fusion process but a neutron capture/absorption process. In 2002, a related tabletop form of thermonuclear fusion was discovered in the field of acoustic inertial confinement fusion. We briefly review some of this work, as well.

To improve the results of obstructive jaundice management by rational diagnostic and treatment strategies. Outcomes of 820 patients with obstructive jaundice syndrome were analyzed. Diagnostic and tactical mistakes were made at pre-hospital stage in 143 (17.4%) patients and in 105 (12.8%) at hospital stage. Herewith, in 53 (6.5%) cases the errors were observed at all stages. Retrospective analysis of severe postoperative complications and lethal outcomes in patients with obstructive jaundice showed that in 23.8% of cases they were explained by diagnostic and tactical mistakes at various stages of examination and treatment. We developed an algorithm for obstructive jaundice management to reduce the number of diagnostic and tactical errors, a reduction in the frequency of diagnostic and tactical errors. It reduced the number of postoperative complications up to 16.5% and mortality rate to 3.0%.

It is well known that Leonardo da Vinci made several drawings of the human male anatomy. The early drawings (before 1500) were incorrect in identifying the origin of semen, where he followed accepted teaching of his time. It is widely thought that he did not correct this mistake, a view that is reflected in several biographies. In fact, he made a later drawing (after 1500) in which the description of the anatomy is remarkably accurate and must have been based on careful dissection. In addition to highlighting this fact, acknowledged previously in only one other source, this article reviews the background to Leonardo's knowledge of the relevant anatomy.

Putting politics first.

PubMed

Hacker, Jacob S

2008-01-01

The greatest lesson of the failure of comprehensive health reform in the early 1990s is that politics comes first. Even the best-laid policy plans are worthless if they lack the political support to pass. Putting politics first means avoiding the overarching mistake of the Clinton reformers: envisioning a grand policy compromise rather than hammering out a real political compromise. It also means addressing the inevitable fears of those who believe that they are well protected by our eroding employment-based system. And it means formulating political strategies that are premised on the contemporary realities of the hyperpolarized U.S. political environment, rather than wistfully recalled images of the bipartisan politics of old.

Social appearance anxiety and dietary restraint as mediators between perfectionism and binge eating: A six month three wave longitudinal study.

PubMed

Brosof, Leigh C; Levinson, Cheri A

2017-01-01

Binge eating is related to perfectionism and restrained eating. However, the mechanisms underlying these relationships are not well understood. It is possible that social anxiety, specifically social appearance anxiety (i.e., the fear of overall appearance evaluation), influences the relationship between binge eating, perfectionism, and dietary restraint. In the current study (N = 300 women), we tested the relationship between dietary restraint, social appearance anxiety, concern over mistakes (a component of perfectionism), and binge eating in prospective data (three time points: at baseline, at two month, and at six month follow up). We found that social appearance anxiety, dietary restraint, and concern over mistakes each predicted binge eating at baseline. Only social appearance anxiety prospectively predicted binge eating when accounting for all variables. Further, in the tested model, social appearance anxiety mediated the relationship between concern over mistakes and binge eating across six months. On the contrary, dietary restraint did not mediate the relationship between concern over mistakes and binge eating in the tested model. The finding that social appearance anxiety served as a mediator between concern over mistakes and binge eating, but that dietary restraint did not, implies that social appearance anxiety may be a more salient prospective predictor of binge eating than dietary restraint. Intervening on social appearance anxiety may be important in the treatment and prevention of binge eating. Copyright © 2016 Elsevier Ltd. All rights reserved.

Effect of implementing instructional videos in a physical examination course: an alternative paradigm for chiropractic physical examination teaching.

PubMed

Zhang, Niu; Chawla, Sudeep

2012-01-01

This study examined the effect of implementing instructional video in ophthalmic physical examination teaching on chiropractic students' laboratory physical examination skills and written test results. Instructional video clips of ophthalmic physical examination, consisting of both standard procedures and common mistakes, were created and used for laboratory teaching. The video clips were also available for student review after class. Students' laboratory skills and written test results were analyzed and compared using one-way analysis of variance (ANOVA) and post hoc multiple comparison tests among three study cohorts: the comparison cohort who did not utilize the instructional videos as a tool, the standard video cohort who viewed only the standard procedure of video clips, and the mistake-referenced video cohort who viewed video clips containing both standard procedure and common mistakes. One-way ANOVA suggested a significant difference of lab results among the three cohorts. Post hoc multiple comparisons further revealed that the mean scores of both video cohorts were significantly higher than that of the comparison cohort (p < .001). There was, however, no significant difference of the mean scores between the two video cohorts (p > .05). However, the percentage of students having a perfect score was the highest in the mistake-referenced video cohort. There was no significant difference of written test scores among all three cohorts (p > .05). The instructional video of the standard procedure improves chiropractic students' ophthalmic physical examination skills, which may be further enhanced by implementing a mistake-referenced instructional video.

Troublesome Crystal Structures: Prevention, Detection, and Resolution

PubMed Central

Harlow, Richard L.

1996-01-01

A large number of incorrect crystal structures is being published today. These structures are proving to be a particular problem to those of us who are interested in comparing structural moieties found in the databases in order to develop structure-property relationships. Problems can reside in the input data, e.g., wrong unit cell or low quality intensity data, or in the structural model, e.g., wrong space group or atom types. Many of the common mistakes are, however, relatively easy to detect and thus should be preventable; at the very least, suspicious structures can be flagged, if not by the authors then by the referees and, ultimately, the crystallographic databases. This article describes some of the more common mistakes and their effects on the resulting structures, lists a series of tests that can be used to detect incorrect structures, and makes a strong plea for the publication of higher quality structures.

2011-12-01

The present study aimed to find which type of stressors correlating to academic performance in second year medical students. One-hundred and eighty three second year medical students of Thammasat University participated in a three-week cross-sectional study. The self-report questionnaire consisted of Thai stress test, stress factors and examination grades referring academic performance were applied in the present study. Females felt stress more than males in severe, high, and medium level of stress. There was no low level of stress and no correlation between stress level and the entrance programs. Academic performance found relating to 1) fear of doing a mistake, 2) feeling of competition or comparison, 3) unilateral headache, 4) worrying, and 5) poor concentration. Students with poor concentration had significantly decreasing grade in the second year (p < 0.01). Interestingly, worrying, feeling of competition or comparison, and fear of doing a mistake correlated to increasing grade in some terms (p < 0.05). Specifically to poor concentration, there were medium linear association with fatigue, poor memory, feeling confused, feeling sad, feeling angry or irritable, changing appetite, and headache from stress (p < 0.01). Poor concentration was the only stressor significantly correlated with poorer academic performance. Poor concentration also correlated with physical, cognitive, and financial problems. The recommendation is to keep watching those issues in order to early detect problem about academic performance.

Are visual cues helpful for virtual spatial navigation and spatial memory in patients with mild cognitive impairment or Alzheimer's disease?

To evaluate whether visual cues are helpful for virtual spatial navigation and memory in Alzheimer's disease (AD) and patients with mild cognitive impairment (MCI). 20 patients with AD, 18 patients with MCI and 20 age-matched healthy controls (HC) were included. Participants had to actively reproduce a path that included 5 intersections with one landmark at each intersection that they had seen previously during a learning phase. Three cueing conditions for navigation were offered: salient landmarks, directional arrows and a map. A path without additional visual stimuli served as control condition. Navigation time and number of trajectory mistakes were recorded. With the presence of directional arrows, no significant difference was found between groups concerning the number of trajectory mistakes and navigation time. The number of trajectory mistakes did not differ significantly between patients with AD and patients with MCI on the path with arrows, the path with salient landmarks and the path with a map. There were significant correlations between the number of trajectory mistakes under the arrow condition and executive tests, and between the number of trajectory mistakes under the salient landmark condition and memory tests. Visual cueing such as directional arrows and salient landmarks appears helpful for spatial navigation and memory tasks in patients with AD and patients with MCI. This study opens new research avenues for neuro-rehabilitation, such as the use of augmented reality in real-life settings to support the navigational capabilities of patients with MCI and patients with AD.

Mira, José Joaquín; Lorenzo, Susana; Guilabert, Mercedes; Navarro, Isabel; Pérez-Jover, Virtudes

2015-06-01

Medication errors have been analyzed as a health professionals' responsibility (due to mistakes in prescription, preparation or dispensing). However, sometimes, patients themselves (or their caregivers) make mistakes in the administration of the medication. The epidemiology of patient medication errors (PEs) has been scarcely reviewed in spite of its impact on people, on therapeutic effectiveness and on incremental cost for the health systems. This study reviews and describes the methodological approaches and results of published studies on the frequency, causes and consequences of medication errors committed by patients at home. A review of research articles published between 1990 and 2014 was carried out using MEDLINE, Web-of-Knowledge, Scopus, Tripdatabase and Index Medicus. The frequency of PE was situated between 19 and 59%. The elderly and the preschooler population constituted a higher number of mistakes than others. The most common were: incorrect dosage, forgetting, mixing up medications, failing to recall indications and taking out-of-date or inappropriately stored drugs. The majority of these mistakes have no negative consequences. Health literacy, information and communication and complexity of use of dispensing devices were identified as causes of PEs. Apps and other new technologies offer several opportunities for improving drug safety.

Electrophysiological correlates of oxytocin-induced enhancement of social performance monitoring.

PubMed

de Bruijn, Ellen R A; Ruissen, Margit I; Radke, Sina

2017-10-01

Altered performance monitoring has been demonstrated after administration of different pharmacological compounds and in various clinical populations, such as excessive neurophysiological responses to mistakes in anxiety disorders. Here, a novel social pharmacological approach was applied to investigate whether oxytocin administration (24 IU) enhances performance monitoring for errors that have negative consequences for another individual, so-called social mistakes. Healthy male volunteers (N = 24) participated in a placebo-controlled crossover design. EEG measures were obtained while pairs of participants performed a speeded choice reaction-time task in an individual and social context. Following oxytocin administration, error-related negativity amplitudes were increased for social compared with individual mistakes. This increase was not found in the placebo condition. No effects of oxytocin were present in the individual context. The current study shows that oxytocin enhances performance monitoring specifically for social mistakes. This outcome is in line with a presumed role for oxytocin in salience attribution to social cues and underlines its context-dependency. Combining these processes may thus open up new research avenues and advance our understanding of individual differences in performance monitoring and oxytocin responses from a social neurocognitive, pharmacological and clinical perspective. © The Author (2017).

Error and its meaning in forensic science.

Christensen, Angi M; Crowder, Christian M; Ousley, Stephen D; Houck, Max M

2014-01-01

The discussion of "error" has gained momentum in forensic science in the wake of the Daubert guidelines and has intensified with the National Academy of Sciences' Report. Error has many different meanings, and too often, forensic practitioners themselves as well as the courts misunderstand scientific error and statistical error rates, often confusing them with practitioner error (or mistakes). Here, we present an overview of these concepts as they pertain to forensic science applications, discussing the difference between practitioner error (including mistakes), instrument error, statistical error, and method error. We urge forensic practitioners to ensure that potential sources of error and method limitations are understood and clearly communicated and advocate that the legal community be informed regarding the differences between interobserver errors, uncertainty, variation, and mistakes. © 2013 American Academy of Forensic Sciences.

Experience gained in the last four years concerning the capabilities and limitations of an 8K Elliott 903 (18-bit word) computer with magnetic tape backing store in the routine operation of a clinical chemistry laboratory is described. Designed as a total system, routine operation has latterly had to be confined to data acquisition and process control functions, due primarily to limitations imposed by the choice of hardware early in the project. In this final report of a partially successful experiment the opportunity is taken to review mistakes made, especially at the start of the project, to warn potential computer users of pitfalls to be avoided.

With the graying of the professoriate, many deans in nursing are moving toward retirement, which provides an opportunity for emerging leaders to move into deanships. New deans move through predictable stages and enjoy a honeymoon, allowing for some mistakes that might not be tolerated later. Early wins are essential in addition to planned changes so as not to overwhelm faculty with change. It is critical to learn the new culture, identify leaders, perform a thorough assessment as the basis for a strategic plan, and be honest and transparent. The ability to mobilize a cohesive, functioning team is critical to success. Copyright © 2012 Elsevier Inc. All rights reserved.

Supervised learning of tools for content-based search of image databases

NASA Astrophysics Data System (ADS)

Delanoy, Richard L.

1996-03-01

A computer environment, called the Toolkit for Image Mining (TIM), is being developed with the goal of enabling users with diverse interests and varied computer skills to create search tools for content-based image retrieval and other pattern matching tasks. Search tools are generated using a simple paradigm of supervised learning that is based on the user pointing at mistakes of classification made by the current search tool. As mistakes are identified, a learning algorithm uses the identified mistakes to build up a model of the user's intentions, construct a new search tool, apply the search tool to a test image, display the match results as feedback to the user, and accept new inputs from the user. Search tools are constructed in the form of functional templates, which are generalized matched filters capable of knowledge- based image processing. The ability of this system to learn the user's intentions from experience contrasts with other existing approaches to content-based image retrieval that base searches on the characteristics of a single input example or on a predefined and semantically- constrained textual query. Currently, TIM is capable of learning spectral and textural patterns, but should be adaptable to the learning of shapes, as well. Possible applications of TIM include not only content-based image retrieval, but also quantitative image analysis, the generation of metadata for annotating images, data prioritization or data reduction in bandwidth-limited situations, and the construction of components for larger, more complex computer vision algorithms.

There is a large body of research about perfectionism and low self-esteem in eating disorders (ED). However, little is known about the influence in ED of a distorted cognition in the domain of control: the perception of low control. The present study examined the main and interactive effects of concern over mistakes (an important dimension of perfectionism), self-esteem, and perception of control on drive for thinness, bulimia, and body dissatisfaction. Forty individuals with ED and 55 controls completed the Multidimensional Perfectionism Scale, the Anxiety Control Questionnaire, the Rosenberg self-esteem scale, and the three symptomatic scales of the Eating Disorder Inventory, which are drive for thinness, bulimia and body dissatisfaction. Multiple linear regression was used to test the hypothesis that perception of low control has a significant effect on the symptomatic scales of the EDI. The ED group had significantly lower perception of control and self-esteem and higher concern over mistakes, drive for thinness, bulimia, and body dissatisfaction than the control group. Analysis of interactive effects suggested that a combination of a low perception of control and a low self-esteem seems to moderate the effects of concern over mistakes on drive for thinness, bulimia, and body dissatisfaction. ED are associated with a tendency to worry about mistakes, a low sense of self-esteem, and a low perception of control over internal feelings and external events. Perception of control and self-esteem seems to moderate the predictive power of concern mistakes on symptoms of ED. The results suggest that a low perception of control is an important cognitive factor in ED.

Despite the continuing emphasis on the importance of clinical skills, these skills do not appear to be improving and may actually be declining. The 'unity of knowledge and action' is a medicine directed precisely at this disease. The 'unity of knowledge and action' helps to learn from failure and successes, learn from mistakes of predecessors and institute a behaviour that prevents repetition of these mistakes.

Graduate medical students often get less opportunity for clarifying their doubts and to reinforce their concepts after lecture classes. The Medical Council of India (MCI) encourages group discussions among students. We evaluated the effect of identifying mistakes in a given set of wrong statements and their correction by a small group discussion by graduate medical students as a revision exercise. At the end of a module, a pre-test consisting of multiple-choice questions (MCQs) was conducted. Later, a set of incorrect statements related to the topic was given to the students and they were asked to identify the mistakes and correct them in a small group discussion. The effects on low, medium and high achievers were evaluated by a post-test and delayed post-tests with the same set of MCQs. The mean post-test marks were significantly higher among all the three groups compared to the pre-test marks. The gain from the small group discussion was equal among low, medium and high achievers. The gain from the exercise was retained among low, medium and high achievers after 15 days. Identification of mistakes in statements and their correction by a small group discussion is an effective, but unconventional revision exercise in biochemistry. Copyright 2014, NMJI.

Strengths, weaknesses, opportunities, and threats analysis of integrating the World Health Organization patient safety curriculum into undergraduate medical education in Pakistan: a qualitative case study.

The purpose of this study was to conduct a strengths, weaknesses, opportunities, and threats (SWOT) analysis of integrating the World Health Organization (WHO) patient safety curriculum into undergraduate medical education in Pakistan. A qualitative interpretive case study was conducted at Riphah International University, Islamabad, from October 2016 to June 2017. The study included 9 faculty members and 1 expert on patient safety. The interviews were audiotaped, and a thematic analysis of the transcripts was performed using NVivo software. Four themes were derived based on the need analysis model. The sub-themes derived from the collected data were arranged under the themes of strengths, weaknesses, opportunities, and threats, in accordance with the principles of SWOT analysis. The strengths identified were the need for a formal patient safety curriculum and its early integration into the undergraduate program. The weaknesses were faculty awareness and participation in development programs. The opportunities were an ongoing effort to develop an appropriate curriculum, to improve the current culture of healthcare, and to use the WHO curricular resource guide. The threats were attitudes towards patient safety in Pakistani culture, resistance to implementation from different levels, and the role of regulatory authorities. The theme of patient safety needs to be incorporated early into the formal medical education curriculum, with the main goals of striving to do no harm and seeing mistakes as opportunities to learn. Faculty development activities need to be organized, and faculty members should to be encouraged to participate in them. The lack of a patient safety culture was identified as the primary reason for resistance to this initiative at many levels. The WHO curriculum, amended according to local institutional culture, can be implemented appropriately with support from the corresponding regulatory bodies.

2017-02-01

Introduction  For the long-term treatment of obstructive lung diseases inhalation therapy with drugs being delivered directly to the lungs as an aerosol has become the method of choice. However, patient-related mistakes in inhalation techniques are frequent and recognized to be associated with reduced disease control. Since the assessment of patient-mistakes in inhalation has yet not been standardized, the present study was aimed at developing checklists for the assessment of correct inhalation. Methods  Checklists were developed in German by an expert panel of pneumologists and professionally translated into English following back-translation procedures. The checklists comparably assessed three major steps of inhalation: 1) inhalation preparation, 2) inhalation routine, and 3) closure of inhalation. Results  Checklists for eight frequently used inhalers were developed: Aerolizer, Breezhaler, Diskus (Accuhaler), metered-dose inhaler, Handihaler, Novolizer, Respimat, Turbohaler. Each checklist consists of ten items: three for inhalation preparation, six for inhalation routine, and one for closure of inhalation. Discussion  Standardized checklists for frequently used inhalers are available in German and English. These checklists can be used for clinical routines or for clinical trials. All checklists can be downloaded free of charge for non-profit application from the homepage of the German Airway League (Deutsche Atemwegsliga e. V.): www.atemwegsliga.de. © Georg Thieme Verlag KG Stuttgart · New York.

Summary Exposures to environmental pollutants during windows of developmental vulnerability in early life can cause disease and death in infancy and childhood as well as chronic, non-communicable diseases that may manifest at any point across the life span. Patterns of pollution and pollution-related disease change as countries move through economic development. Environmental pollution is now recognized as a major cause of morbidity and mortality in low- and middle-income countries (LMICs). According to the World Health Organization, pollution is responsible for 8.9 million deaths around the world each year; of these, 94% (8.4 million) are in LMICs. Toxic chemical pollution is growing into a major threat to children’s health in LMICs. The disease and disability caused by environmental pollution have great economic costs, and these costs can undercut trajectories of national development. To combat pollution, improved programs of public health and environmental protection are needed in countries at every level of development. Pollution control strategies and technologies that have been developed in high-income countries must now be transferred to LMICs to assist these emerging economies to avoid the mistakes of the past. A new international clearinghouse is needed to define and track the health effects of pollution, quantify the economic costs of these effects, and direct much needed attention to environmental pollution as a risk factor for disease.

Two spatiotemporally distinct value systems shape reward-based learning in the human brain.

Fouragnan, Elsa; Retzler, Chris; Mullinger, Karen; Philiastides, Marios G

2015-09-08

Avoiding repeated mistakes and learning to reinforce rewarding decisions is critical for human survival and adaptive actions. Yet, the neural underpinnings of the value systems that encode different decision-outcomes remain elusive. Here coupling single-trial electroencephalography with simultaneously acquired functional magnetic resonance imaging, we uncover the spatiotemporal dynamics of two separate but interacting value systems encoding decision-outcomes. Consistent with a role in regulating alertness and switching behaviours, an early system is activated only by negative outcomes and engages arousal-related and motor-preparatory brain structures. Consistent with a role in reward-based learning, a later system differentially suppresses or activates regions of the human reward network in response to negative and positive outcomes, respectively. Following negative outcomes, the early system interacts and downregulates the late system, through a thalamic interaction with the ventral striatum. Critically, the strength of this coupling predicts participants' switching behaviour and avoidance learning, directly implicating the thalamostriatal pathway in reward-based learning.

Mistakes in the usage of anatomical terminology in clinical practice.

Anatomical terminology serves as a basic communication tool in all the medical fields. Therefore Latin anatomical nomenclature has been repetitively issued and revised from 1895 (Basiliensia Nomina Anatomica) until 1998, when the last version was approved and published as the Terminologia Anatomica (International Anatomical Terminology) by the Federative Committee on Anatomical Terminology. A brief history of the terminology and nomenclature development is mentioned, along with the concept and contributions of the Terminologia Anatomica including the employed abbreviations. Examples of obsolete anatomical terms and their current synonyms are listed. Clinicians entered the process of the nomenclature revision and this aspect is demonstrated with several examples of terms used in clinical fields only, some already incorporated in the Terminologia Anatomica and a few obsolete terms still alive in non-theoretical communication. Frequent mistakes in grammar and orthography are stated as well. Authors of the article strongly recommend the use of the recent revision of the Latin anatomical nomenclature both in theoretical and clinical medicine.

Making agreements on how to behave has been shown to be an evolutionarily viable strategy in one-shot social dilemmas. However, in many situations agreements aim to establish long-term mutually beneficial interactions. Our analytical and numerical results reveal for the first time under which conditions revenge, apology and forgiveness can evolve and deal with mistakes within ongoing agreements in the context of the Iterated Prisoners Dilemma. We show that, when the agreement fails, participants prefer to take revenge by defecting in the subsisting encounters. Incorporating costly apology and forgiveness reveals that, even when mistakes are frequent, there exists a sincerity threshold for which mistakes will not lead to the destruction of the agreement, inducing even higher levels of cooperation. In short, even when to err is human, revenge, apology and forgiveness are evolutionarily viable strategies which play an important role in inducing cooperation in repeated dilemmas.

The healthcare organization is the place where defects and mistakes cannot be tolerated. A simple mistake can cost a human life so defects or mistakes must be eliminated in healthcare service processes. A Lean Six Sigma (LSS) approach is the best option in a healthcare environment for dealing with a critical patient. The LSS methodology optimizes the average reduction of a desired process. The expected results can be reductions in several aspects of healthcare such as patient waiting time in emergency departments, lost charges for billing in patient financial services, delinquent medical records, diagnostic result turnaround times, accounts receivable days, patients' length of stay, or medication errors. This paper mainly discusses the effects of the LSS approach in different hospitals around the world according to the literature review. This review also discusses the relationship between LSS as well as their impacts on healthcare services based on literature review.

Recognizing Prefixes in Scientific Quantities

NASA Astrophysics Data System (ADS)

Sokolowski, Andrzej

2015-09-01

Although recognizing prefixes in physical quantities is inherent for practitioners, it might not be inherent for students, who do not use prefixes in their everyday life experiences. This deficiency surfaces in AP Physics exams. For example, readers of an AP Physics exam reported "a common mistake of incorrectly converting nanometers to meters." Similar students' mistakes were reported also by AP Chemistry readers "as in previous years, students still had difficulty converting kJ to J." While traditional teaching focuses on memorizing the symbols of prefixes, little attention is given to helping learners recognize a prefix in a given quantity. I noticed in my teaching practice that by making the processes of identifying prefixes more explicit, students make fewer mistakes on unit conversion. Thus, this paper presents an outline of a lesson that focuses on prefix recognition. It is designed for a first-year college physics class; however, its key points can be addressed to any group of physics students.

The endocrinological emergency of a fully blown myxedema crisis can present as a multicolored clinical picture. This can obscure the underlying pathology and easily lead to mistakes in clinical diagnosis, work-up, and treatment. We present a case of an unconscious 39-year-old patient with a medical history of weakness, lethargy, and findings of hyponatremia, intracerebral bleeding, and massive pericardial effusion. Finally, myxedema crisis was diagnosed as underlying cause. Replacement therapy of thyroid hormone and conservative management of the intracerebral bleeding resulted in patient's survival without significant neurological impairment. However, diagnostic pericardiocentesis resulted in life-threatening pericardial tamponade. It is of tremendous importance to diagnose myxoedema crisis early to avoid adverse health outcomes.

Augmenting intracortical brain-machine interface with neurally driven error detectors

Even-Chen, Nir; Stavisky, Sergey D.; Kao, Jonathan C.; Ryu, Stephen I.; Shenoy, Krishna V.

2017-12-01

Objective. Making mistakes is inevitable, but identifying them allows us to correct or adapt our behavior to improve future performance. Current brain-machine interfaces (BMIs) make errors that need to be explicitly corrected by the user, thereby consuming time and thus hindering performance. We hypothesized that neural correlates of the user perceiving the mistake could be used by the BMI to automatically correct errors. However, it was unknown whether intracortical outcome error signals were present in the premotor and primary motor cortices, brain regions successfully used for intracortical BMIs. Approach. We report here for the first time a putative outcome error signal in spiking activity within these cortices when rhesus macaques performed an intracortical BMI computer cursor task. Main results. We decoded BMI trial outcomes shortly after and even before a trial ended with 96% and 84% accuracy, respectively. This led us to develop and implement in real-time a first-of-its-kind intracortical BMI error ‘detect-and-act’ system that attempts to automatically ‘undo’ or ‘prevent’ mistakes. The detect-and-act system works independently and in parallel to a kinematic BMI decoder. In a challenging task that resulted in substantial errors, this approach improved the performance of a BMI employing two variants of the ubiquitous Kalman velocity filter, including a state-of-the-art decoder (ReFIT-KF). Significance. Detecting errors in real-time from the same brain regions that are commonly used to control BMIs should improve the clinical viability of BMIs aimed at restoring motor function to people with paralysis.

Challenge of emerging technologies: balancing the needs of law enforcement against the duty to protect individual rights

NASA Astrophysics Data System (ADS)

Lingerfelt, James A.

1997-01-01

This paper discusses three emerging technologies which will revolutionize the business operations of law enforcement: databases and search engines; biometric identification systems; and electronic surveillance and tracking devices. Unfortunately, these technologies may also lead to a serious ethical conflict for law enforcement. The tools will make it easier than ever to accomplish the core business of policing: crime prevention; investigation; and intelligence gathering. The same tools, used improperly, will also lead to routine intrusions on personal privacy. These technologies have been and are being developed for the private sector, the military and the intelligence community. The vendors are now aggressively marketing them to law enforcement and criminal justice agencies. The law enforcement community has embraced the technology, but without considering the long term impact. In the past, the police have abused wiretaps and other early surveillance technology. As a result, a sinister perception about police surveillance practices persists and a cumbersome bureaucracy has been imposed to control their use. Developing and establishing policies governing the use of emerging technologies can prevent these mistakes from being repeated. This paper recommends that criminal justice practitioners begin a discussion now, in advance of these technologies becoming commercially available, with a view to defining clear guidelines for their proper use.

Radiography student perceptions of clinical stressors.

PubMed

Mason, Starla L

2006-01-01

Technological change and the increasingly rapid pace of life in the United States and globally have contributed to increased levels of stress and burnout experienced by workers and their families. Although studies are available on the levels of workplace stress and burnout affecting radiographers, little to no research has been conducted to assess the stressors encountered by radiography students in the clinical environment. This study was designed to pinpoint the primary sources of stress for radiography students and to determine the most effective measures to alleviate the stress that students experience in the clinical environment. It also sought to identify the clinical activities and practices that enhance learning. A convenience sample of radiography students attending an Association of Collegiate Educators in Radiologic Technology meeting was surveyed. Students were asked to rank their greatest stressors in the clinical environment, the most desired qualities in a clinical instructor and clinical environment, and the clinical practices and activities that best enhance their learning. Descriptive statistics were used to report the results. Data were collected for 82 first-year and second-year students. Students identified 7 primary clinical stressors: fear of making a mistake/repeat, feeling unprepared/inexperienced, intimidation by staff and by instructors, difficult/critical patients, hurtful criticism, too much supervision and negative responses to questions/requests for help. Students indicated that more frequent feedback, availability of the clinical instructor and other staff, assurance that mistakes happen and the opportunity to make mistakes were clinical practices that eased stress. The majority of students cited hands-on learning and repetition as the clinical activities that most reinforced their learning. Summary Radiography students in this survey experience some of the same clinical stressors as radiographers and other allied health workers, although the source of stress may be different. Factors that promote an optimum clinical learning environment for students include instructor availability, opportunities to practice skills and make mistakes, frequent performance feedback and assurance that mistakes happen.

Most Frequent Errors in Judo Uki Goshi Technique and the Existing Relations among Them Analysed through T-Patterns

PubMed Central

Gutiérrez, Alfonso; Prieto, Iván; Cancela, José M.

2009-01-01

The purpose of this study is to provide a tool, based on the knowledge of technical errors, which helps to improve the teaching and learning process of the Uki Goshi technique. With this aim, we set out to determine the most frequent errors made by 44 students when performing this technique and how these mistakes relate. In order to do so, an observational analysis was carried out using the OSJUDO-UKG instrument and the data were registered using Match Vision Studio (Castellano, Perea, Alday and Hernández, 2008). The results, analyzed through descriptive statistics, show that the absence of a correct initial unbalancing movement (45,5%), the lack of proper right-arm pull (56,8%), not blocking the faller’s body (Uke) against the thrower’s hip -Tori- (54,5%) and throwing the Uke through the Tori’s side are the most usual mistakes (72,7%). Through the sequencial analysis of T-Patterns obtained with the THÈME program (Magnusson, 1996, 2000) we have concluded that not blocking the body with the Tori’s hip provokes the Uke’s throw through the Tori’s side during the final phase of the technique (95,8%), and positioning the right arm on the dorsal region of the Uke’s back during the Tsukuri entails the absence of a subsequent pull of the Uke’s body (73,3%). Key Points In this study, the most frequent errors in the performance of the Uki Goshi technique have been determined and the existing relations among these mistakes have been shown through T-Patterns. The SOBJUDO-UKG is an observation instrument for detecting mistakes in the aforementioned technique. The results show that those mistakes related to the initial imbalancing movement and the main driving action of the technique are the most frequent. The use of T-Patterns turns out to be effective in order to obtain the most important relations among the observed errors. PMID:24474885

Advocates of RI in research policy argue that scientific research should be opened up at an early stage so that many actors and issues can steer innovation trajectories. If this is done, they suggest, new technologies will be more responsible in different ways, better aligned with what society wants, and mistakes of the past will be avoided. This paper analyses the dynamics of RI in policy and practice and makes recommendations for future development. More specifically, we draw on the theory of 'trading zones' developed by Peter Galison and use it to analyse two related processes: (i) the development and inclusion of RI in research policy at the UK's Engineering and Physical Sciences Research Council (EPSRC); (ii) the implementation of RI in relation to the Stratospheric Particle Injection for Climate Engineering (SPICE) project. Our analysis reveals an RI trading zone comprised of three quasi-autonomous traditions of the research domain - applied science, social science and research policy. It also shows how language and expertise are linking and coordinating these traditions in ways shaped by local conditions and the wider context of research. Building on such insights, we argue that a sensible goal for RI policy and practice at this stage is better local coordination of those involved and we suggest ways how this might be achieved.

In our recent paper [1], we reported the synthesis of hydroxyapatite/multi-walled carbon nanotubes (HA-MWCNTs) and studied their performance for the removal of fluoride ions from solution. However, we have made some writing mistakes, especially in the section on adsorption kinetics analysis. Our mistakes were spotted by Prof. Yuandong Huang, who graciously noticed these errors. We are grateful to him, and have decided to write a "Corrigendum".

An earlier calculation of the I-V characteristics of solar cells contains a mistake. The current generated by light within the depletion layer is too large by a factor of 2. When this mistake is corrected, not only are all previous conclusions unchanged, but the agreement with experiment becomes better. Results are presented in graphical form of new computations which not only take account of the factor of 2, but also include more recent data on material parameters.

NORMAL HUMAN VARIATION: REFOCUSSING THE ENHANCEMENT DEBATE

PubMed Central

Kahane, Guy; Savulescu, Julian

2015-01-01

This article draws attention to several common mistakes in thinking about biomedical enhancement, mistakes that are made even by some supporters of enhancement. We illustrate these mistakes by examining objections that John Harris has recently raised against the use of pharmacological interventions to directly modulate moral decision-making. We then apply these lessons to other influential figures in the debate about enhancement. One upshot of our argument is that many considerations presented as powerful objections to enhancement are really strong considerations in favour of biomedical enhancement, just in a different direction. Another upshot is that it is unfortunate that much of the current debate focuses on interventions that will radically transform normal human capacities. Such interventions are unlikely to be available in the near future, and may not even be feasible. But our argument shows that the enhancement project can still have a radical impact on human life even if biomedical enhancement operated entirely within the normal human range. PMID:23906367

This research aims at describing the profile of high school teacher’s Pedagogical Content Knowledge in learning mathematics from the perspective of teaching experience. Pedagogical Content Knowledge (PCK) covers teacher’s knowledge of subject matter, knowledge of pedagogy, and knowledge of students. The subject of this research was two high school mathematics teachers who have different teaching experience. The data were obtained through interview and observation then analyzed qualitatively. The focus of this research is the novice teacher’s PCK deals with knowledge of students. Knowledge of Student is defined as teacher’s knowledge about the students’ conception and misconception on limit of function material and teacher’s ability to cope with students’ difficulty, mistake, and misconception. The result of this research shows that novice teacher’s ability in analyzing the cause of students’ difficulty, mistake, and misconception was limited. Novice teacher tended to overcome the students’ difficulty, mistake, and misconception by re-explaining the procedure of question completion which is not understood by the students.

The Language of Fairness: how Cross-Linguistic Norms in Spanish and English Influence Reactions to Unfair Treatment.

PubMed

Birk, Sam J; Kausel, Edgar E

2016-11-14

We integrate recent findings from the linguistics literature with the organizational justice literature to examine how the language used to encode justice violations influences fairness perceptions. The study focused on the use of non-agentive syntax to encode mistakes in Spanish ("The vase was broken") versus using agentive syntax in English ("She broke the vase") influences event fairness perceptions. We hypothesized that when justice violations are encoded using Spanish, because the non-agentive syntax makes the responsible party less salient, the event would be perceived as less unfair. In Study 1 (n = 111), English-speaking participants rated the fairness of an event in which a mistake was made and an employee received a negative outcome. They rated it as more unfair (p < .01, η2 = .06) when the scenario was presented in agentive syntax. Experiment 2 (n = 70) used native English- and Spanish-speakers who watched a video of manager making a mistake. We found that Spanish-speakers used less agentive syntax (p < .01, η2 = .21), perceived the event as less unfair (p < .001, η2 = .23), and were more willing to help the manager who made the mistake. In Experiment 3 (n = 101) we replicated this effect controlling for cross-cultural differences and native language; further, we found an interaction between entity fairness (event vs. entity) and native language (Spanish vs. English) on citizenship intentions (p < .01, η2 = .08). These results extend our understanding of how language may influence relevant workplace attitudes.

Polarimeter calibration error gets far out of control

This is a sad story about a polarization calibration error gone amuck. A simple laboratory mistake was mistaken for a new phenomena. Aggressive management did their job and sold the flawed idea very effectively and substantial funding followed. Questions were raised and a Government lab tried but couldn't to recreate the breakthrough. The results were unpleasant and the field of infrared polarimetry developed a bad reputation for several years.

Hiring: take your time but not too much

NASA Astrophysics Data System (ADS)

Usher, Linda

2010-08-01

People are any company's greatest asset. Without a great team no company would be able to conceive of a product or service. It would not be able to design or develop a product or service. It could not possibly market or sell that product or service. How a company goes about hiring its talent is one of the most critical components to developing a great team, to having low attrition, and to having a high level of employee faith in management. Far too often I have seen companies when tasked with filling requisitions not take the time to consider, or layout and execute their priorities in hiring. It's a pretty safe assumption that if one doesn't feel they have enough time to be careful and thorough in their hiring approach in order to get the right person the first time - they probably won't have enough time to replace someone they would not have hired had they done it right in the first place! The flip side of this is the problem of letting too much time pass in the process and therefore losing opportunities to hire great people. This paper will point out many mistakes I have seen made in hiring approaches so that hopefully, different strategies can be adopted to avoid those mistakes in the future.

X-ray computed tomography datasets for forensic analysis of vertebrate fossils.

2016-06-07

We describe X-ray computed tomography (CT) datasets from three specimens recovered from Early Cretaceous lakebeds of China that illustrate the forensic interpretation of CT imagery for paleontology. Fossil vertebrates from thinly bedded sediments often shatter upon discovery and are commonly repaired as amalgamated mosaics grouted to a solid backing slab of rock or plaster. Such methods are prone to inadvertent error and willful forgery, and once required potentially destructive methods to identify mistakes in reconstruction. CT is an efficient, nondestructive alternative that can disclose many clues about how a specimen was handled and repaired. These annotated datasets illustrate the power of CT in documenting specimen integrity and are intended as a reference in applying CT more broadly to evaluating the authenticity of comparable fossils.

The cognitive therapy of depression rests on substantial theoretical, empirical and clinical foundations: a reply to Dr Gipps

PubMed Central

Moorey, Stirling

2017-01-01

Dr Gipps claims that the cognitive therapy for depression rests on a mistake. But his anachronistic analysis of Beck's early research from the perspective of current psychoanalytic theory misses the point. The value of the research was not that it disproved psychoanalytic theory, but that it generated a model of depression that has revolutionised psychotherapy research. Psychoanalysts are belatedly adopting research methods that Beck pioneered half a century ago. The cognitive model of depression has explanatory power for both maintenance and vulnerability and has substantial research underpinning it. Cognitive therapy for depression has a larger body of evidence for its efficacy and relapse prevention effect than any other psychotherapy. Transference-focused approaches to depression have yet to establish themselves in the same way. PMID:29018552

Motivational processes from expectancy-value theory are associated with variability in the error positivity in young children

Motivational beliefs and values influence how children approach challenging activities. The present study explores motivational processes from an expectancy-value theory framework by studying children's mistakes and their responses to them by focusing on two ERP components, the error-related negativity (ERN) and error positivity (Pe). Motivation was assessed using a child-friendly challenge puzzle task and a brief interview measure prior to ERP testing. Data from 50 four- to six-year-old children revealed that greater perceived competence beliefs were related to a larger Pe, while stronger intrinsic task value beliefs were associated with a smaller Pe. Motivation was unrelated to the ERN. Individual differences in early motivational processes may reflect electrophysiological activity related to conscious error awareness. PMID:27898304

Management of Crush Syndrome Casualties after Disasters

PubMed Central

Sever, Mehmet Sukru; Vanholder, Raymond

2011-01-01

After direct impact of the trauma, crush syndrome is the second most frequent cause of death after mass disasters. However, since crush syndrome is quite rare in daily practice, mistakes are frequent in the treatment of these cases. This paper summarizes the etiopathogenesis of traumatic rhabdomyolysis and of crush syndrome-based acute kidney injury. The clinical and laboratory features, prophylaxis, and treatment of crush cases are described as well. The importance of early and energetic fluid resuscitation is underlined for prophylaxis of acute kidney injury. Since there is chaos, and an overwhelming number of victims, logistic drawbacks create a specific problem in the treatment of crush victims after mass disasters. Potential solutions for logistic hurdles and disaster preparedness scenarios have also been provided in this review article. PMID:23908797

Articulation disorders in young children are due to defects occurring at a certain stage in sensory and motor development. Some children with functional articulation disorders may also have sensory integration dysfunction (SID). We hypothesized that speech therapy would be less efficacious in children with SID than in those without SID. Hence, the purpose of this study was to compare the efficacy of speech therapy in two groups of children with functional articulation disorders: those without and those with SID. A total of 30 young children with functional articulation disorders were divided into two groups, the no-SID group (15 children) and the SID group (15 children). The number of pronunciation mistakes was evaluated before and after speech therapy. There were no statistically significant differences in age, sex, sibling order, education of parents, and pretest number of mistakes in pronunciation between the two groups (P > 0.05). The mean and standard deviation in the pre- and post-test number of mistakes in pronunciation were 10.5 ± 3.2 and 3.3 ± 3.3 in the no-SID group, and 10.1 ± 2.9 and 6.9 ± 3.5 in the SID group, respectively. Results showed great changes after speech therapy treatment (F = 70.393; P < 0.001) and interaction between the pre/post speech therapy treatment and groups (F = 11.119; P = 0.002). Speech therapy can improve the articulation performance of children who have functional articulation disorders whether or not they have SID, but it results in significantly greater improvement in children without SID. SID may affect the treatment efficiency of speech therapy in young children with articulation disorders.

High quality feedback is vital to learning in medical education but many students and teachers have expressed dissatisfaction on current feedback practices. Lack of teachers' insight into students' feedback requirements may be a key, which might be addressed by giving control to the students with student led feedback practices. The conceptual framework was built on three dimensions of learning theory by Illeris and Vygotsky's zone of proximal development and scaffolding. We introduced a feedback session with self-reflection and peer feedback in the form of open discussion on video-recorded student performances under teacher's guidance. The aims of this qualitative study were to explore students' perception on this holistic feedback approach and to investigate ways of maximising effective feedback and learning. Semi-structured interviews were used to gather data which were evaluated using a thematic analytical approach. The participants were third year medical students of Imperial College London on clinical placements at Hillingdon Hospital. Video based self-reflection helped some students to identify mistakes in communication and technical skills of which they were unaware prior to the session. Those who were new to video feedback found their expected self-image different to that of their actual image on video, leading to some distress. However many also identified that mistakes were not unique to themselves through peer videos and learnt from both model performances and from each other's mistakes. Balancing honest feedback with empathy was a challenge for many during peer discussion. The teacher played a vital role in making the session a success by providing guidance and a supportive environment. This study has demonstrated many potential benefits of this holistic feedback approach with video based self-reflection and peer discussion with students engaging at a deeper cognitive level than the standard descriptive feedback.

Exploring Spanish health social media for detecting drug effects.

PubMed

Segura-Bedmar, Isabel; Martínez, Paloma; Revert, Ricardo; Moreno-Schneider, Julián

2015-01-01

Adverse Drug reactions (ADR) cause a high number of deaths among hospitalized patients in developed countries. Major drug agencies have devoted a great interest in the early detection of ADRs due to their high incidence and increasing health care costs. Reporting systems are available in order for both healthcare professionals and patients to alert about possible ADRs. However, several studies have shown that these adverse events are underestimated. Our hypothesis is that health social networks could be a significant information source for the early detection of ADRs as well as of new drug indications. In this work we present a system for detecting drug effects (which include both adverse drug reactions as well as drug indications) from user posts extracted from a Spanish health forum. Texts were processed using MeaningCloud, a multilingual text analysis engine, to identify drugs and effects. In addition, we developed the first Spanish database storing drugs as well as their effects automatically built from drug package inserts gathered from online websites. We then applied a distant-supervision method using the database on a collection of 84,000 messages in order to extract the relations between drugs and their effects. To classify the relation instances, we used a kernel method based only on shallow linguistic information of the sentences. Regarding Relation Extraction of drugs and their effects, the distant supervision approach achieved a recall of 0.59 and a precision of 0.48. The task of extracting relations between drugs and their effects from social media is a complex challenge due to the characteristics of social media texts. These texts, typically posts or tweets, usually contain many grammatical errors and spelling mistakes. Moreover, patients use lay terminology to refer to diseases, symptoms and indications that is not usually included in lexical resources in languages other than English.

Computer-Based Tools for Evaluating Graphical User Interfaces

NASA Technical Reports Server (NTRS)

Moore, Loretta A.

1997-01-01

The user interface is the component of a software system that connects two very complex system: humans and computers. Each of these two systems impose certain requirements on the final product. The user is the judge of the usability and utility of the system; the computer software and hardware are the tools with which the interface is constructed. Mistakes are sometimes made in designing and developing user interfaces because the designers and developers have limited knowledge about human performance (e.g., problem solving, decision making, planning, and reasoning). Even those trained in user interface design make mistakes because they are unable to address all of the known requirements and constraints on design. Evaluation of the user inter-face is therefore a critical phase of the user interface development process. Evaluation should not be considered the final phase of design; but it should be part of an iterative design cycle with the output of evaluation being feed back into design. The goal of this research was to develop a set of computer-based tools for objectively evaluating graphical user interfaces. The research was organized into three phases. The first phase resulted in the development of an embedded evaluation tool which evaluates the usability of a graphical user interface based on a user's performance. An expert system to assist in the design and evaluation of user interfaces based upon rules and guidelines was developed during the second phase. During the final phase of the research an automatic layout tool to be used in the initial design of graphical inter- faces was developed. The research was coordinated with NASA Marshall Space Flight Center's Mission Operations Laboratory's efforts in developing onboard payload display specifications for the Space Station.

Studies of echinoid microscopic anatomy over the last two centuries have created a number of inaccuracies and mistakes that have accumulated in the descriptions of the intricate organization of the coelomic system of Echinoidea. To clarify the situation, we reconstructed the axial complex and radial complex of the echinoid Strongylocentrotus pallidus. The water ring is located between the perivisceral coelom and the perioral coelom. The oral haemal ring lies between the coelothelia of the water-vascular, perivisceral, and perioral rings. The axial part of the axial organ communicates with the oral haemal ring in interradius CD, but the axial coelom does not form the axocoelomic perihaemal ring. The ventral intestinal haemal vessel originates from the oral haemal ring in radius A, and then branches into a network of capillaries, from which the dorsal intestinal vessel starts. The pericardial coelom envelopes the pericardial part of the axial organ, the lacunae of which communicate with the haemocoel of the body wall and with the axial part of the axial organ. The genital haemal ring and the dorsal intestinal vessel communicate with the axial organ. The genital coelom passes in the CD interradius on the side opposite to the hindgut. There is a somatocoelomic perihaemal ring, which sends a pair of coelomic outgrowths into each radius, accompanied by a radial haemal vessel in the oral part. The mistakes and inaccuracies of early descriptions of the echinoid axial complex are listed. The axial complex and associated structures of sea urchins are compared with other eleutherozoans. © 2018 Wiley Periodicals, Inc.

Pubertal growth pattern differs according to age at pubertal growth spurt onset which occurs over a five years period (girls: 8-13 years, boys: 10-15 years). The need for more than one pubertal reference pattern has been proposed. We aimed to obtain five 1-year-age-interval pubertal patterns. Longitudinal (6 years of age-adult height) growth study of 1,453 healthy children to evaluate height-for-age, growth velocity-for-age and weight-for-age values. According to age at pubertal growth spurt onset girls were considered: very-early matures (8-9 years, n=119), early matures (9-10 years, n=157), intermediate matures (10-11 years, n=238), late matures (11-12 years, n=127) and very-late matures (12-13 years, n=102), and boys: very-early matures (10-11 years, n=110), early matures (11-12 years, n=139), intermediate matures (12-13 years, n=225), late matures (13-14 years, n=133) and very-late matures (14-15 years, n=103). Age at menarche and growth up to adult height were recorded. In both sexes, statistically-significant (P<.0001) and clinically-pertinent differences in pubertal growth pattern (mean height-for-age, mean growth velocity-for-age and mean pubertal height gain, values) were found among the five pubertal maturity groups and between each group and the whole population, despite similar adult height values. The same occurred for age at menarche and growth from menarche to adult height (P<.05). In both sexes, pubertal growth spurt onset is a critical milestone determining pubertal growth and sexual development. The contribution of our data to better clinical evaluation of growth according to the pubertal maturity tempo of each child will obviate the mistakes made when only one pubertal growth reference is used.

Automatic speech recognition (ASR) based approach for speech therapy of aphasic patients: A review

NASA Astrophysics Data System (ADS)

Jamal, Norezmi; Shanta, Shahnoor; Mahmud, Farhanahani; Sha'abani, MNAH

2017-09-01

This paper reviews the state-of-the-art an automatic speech recognition (ASR) based approach for speech therapy of aphasic patients. Aphasia is a condition in which the affected person suffers from speech and language disorder resulting from a stroke or brain injury. Since there is a growing body of evidence indicating the possibility of improving the symptoms at an early stage, ASR based solutions are increasingly being researched for speech and language therapy. ASR is a technology that transfers human speech into transcript text by matching with the system's library. This is particularly useful in speech rehabilitation therapies as they provide accurate, real-time evaluation for speech input from an individual with speech disorder. ASR based approaches for speech therapy recognize the speech input from the aphasic patient and provide real-time feedback response to their mistakes. However, the accuracy of ASR is dependent on many factors such as, phoneme recognition, speech continuity, speaker and environmental differences as well as our depth of knowledge on human language understanding. Hence, the review examines recent development of ASR technologies and its performance for individuals with speech and language disorders.

Developing government policies for distance education: Lessons learnt from two Sri Lankan case studies

Education, especially higher education, is considered vital for maintaining national and individual competitiveness in the global knowledge economy. Following the introduction of its "Free Education Policy" as early as 1947, Sri Lanka is now the best performer in basic education in the South Asian region, with a remarkable record in terms of high literacy rates and the achievement of universal primary education. However, access to tertiary education is a bottleneck, due to an acute shortage of university places. In an attempt to address this problem, the government of Sri Lanka has invested heavily in information and communications technologies (ICTs) for distance education. Although this has resulted in some improvement, the authors of this article identify several barriers which are still impeding successful participation for the majority of Sri Lankans wanting to study at tertiary level. These impediments include the lack of infrastructure/resources, low English language proficiency, weak digital literacy, poor quality of materials and insufficient provision of student support. In the hope that future implementations of ICT-enabled education programmes can avoid repeating the mistakes identified by their research in this Sri Lankan case, the authors conclude their paper with a list of suggested policy options.

Asset protection planning is a highly technical area of legal planning. Because of the fraudulent transfer laws, asset protection planning must be done in advance of any claim, be technically sound, not rely upon secrecy, and avoid any number of critical mistakes including keeping personal and business assets separate. Physicians who engage in asset protection planning must avoid critical mistakes, and not count on bankruptcy to provide relief from creditors. General rules and cautions for those who are considering the creation of an asset protection plan for their personal assets.

Our study examined the relationships of relational pronouns used in parental conversation to the quality of early family interactions, as indexed by Family Alliance (FA). We hypothesized that more positive family interactions were associated with the use of more we-pronouns (e.g., we, us, our; we-ness ) and fewer I- and you-pronouns (e.g., I, me, you, your; separateness ) by both mothers and fathers. Our statistical model using a multilevel modeling framework and two levels of analysis (i.e., a couple level and an individual level) was tested on 47 non-referred families ( n = 31 primiparous families; child's age, M = 15.75 months, SD = 2.73) with we-ness and separateness as outcomes and FA functions as between-dyads variables. Analyses revealed that we-ness within the parental couple was only positively associated with family affect sharing while separateness was negatively associated with different FA functions (e.g., communication mistakes). Our main finding suggested that the kinds of personal pronouns used by parental couples when discussing children's education would be associated to the emotional quality of the family interactions.

Two women who were involved in the project formed Higher Order Software, Inc. to develop and market the system of error analysis and correction. They designed software which is logically error-free, which, in one instance, was found to increase productivity by 600%. USE.IT defines its objectives using AXES -- a user can write in English and the system converts to computer languages. It is employed by several large corporations.

Mistaking minds and machines: How speech affects dehumanization and anthropomorphism.

PubMed

Schroeder, Juliana; Epley, Nicholas

2016-11-01

Treating a human mind like a machine is an essential component of dehumanization, whereas attributing a humanlike mind to a machine is an essential component of anthropomorphism. Here we tested how a cue closely connected to a person's actual mental experience-a humanlike voice-affects the likelihood of mistaking a person for a machine, or a machine for a person. We predicted that paralinguistic cues in speech are particularly likely to convey the presence of a humanlike mind, such that removing voice from communication (leaving only text) would increase the likelihood of mistaking the text's creator for a machine. Conversely, adding voice to a computer-generated script (resulting in speech) would increase the likelihood of mistaking the text's creator for a human. Four experiments confirmed these hypotheses, demonstrating that people are more likely to infer a human (vs. computer) creator when they hear a voice expressing thoughts than when they read the same thoughts in text. Adding human visual cues to text (i.e., seeing a person perform a script in a subtitled video clip), did not increase the likelihood of inferring a human creator compared with only reading text, suggesting that defining features of personhood may be conveyed more clearly in speech (Experiments 1 and 2). Removing the naturalistic paralinguistic cues that convey humanlike capacity for thinking and feeling, such as varied pace and intonation, eliminates the humanizing effect of speech (Experiment 4). We discuss implications for dehumanizing others through text-based media, and for anthropomorphizing machines through speech-based media.

(1) To determine the proportion of parents concerned about medical errors during a child's hospitalization; and (2) the association between this concern and parental self-efficacy with physician interactions. Cross-sectional survey. Tertiary care children's hospital. Parents of children admitted to the general medical service. Parental concern about medical errors. : Parents were asked their agreement with the statement "When my child is in the hospital I feel that I have to watch over the care that he/she is receiving to make sure that mistakes aren't made." We used multivariate logistic regression to examine the association between parents' self-efficacy with physician interactions and the need "to watch over a child's care," adjusting for parent and child demographics, English proficiency, past hospitalization, and social desirability bias. Of 278 eligible parents, 130 completed surveys and 63% reported the need to watch over their child's care to ensure that mistakes were not made. Parents with greater self-efficacy with physician interactions were less likely to report this need (odds ratio [OR], 0.83; 95% confidence interval [CI], 0.72-0.92). All parents who were "very uncomfortable" communicating with doctors in English reported the need to watch over their child's care to prevent mistakes. Nearly two-thirds of surveyed parents felt the need to watch over their child's hospital care to prevent mistakes. Parents with greater self-efficacy with physician interactions were less likely to report the need to watch over their child's care while parents with lower English proficiency were more likely to report this need.

A Just Culture Approach to Managing Medication Errors.

Rogers, Erin; Griffin, Emily; Carnie, William; Melucci, Joseph; Weber, Robert J

2017-04-01

Medication errors continue to be a concern of health care providers and the public, in particular how to prevent harm from medication mistakes. Many health care workers are afraid to report errors for fear of retribution including the loss of professional licensure and even imprisonment. Most health care workers are silent, instead of admitting their mistake and discussing it openly with peers. This can result in further patient harm if the system causing the mistake is not identified and fixed; thus self-denial may have a negative impact on patient care outcomes. As a result, pharmacy leaders, in collaboration with others, must put systems in place that serve to prevent medication errors while promoting a "Just Culture" way of managing performance and outcomes. This culture must exist across disciplines and departments. Pharmacy leaders need to understand how to classify behaviors associated with errors, set realistic expectations, instill values for staff, and promote accountability within the workplace. This article reviews the concept of Just Culture and provides ways that pharmacy directors can use this concept to manage the degree of error in patient-centered pharmacy services.

[THE EFFECT OF CLAIMS ABOUT MEDICAL ADVERSE EVENTS ON PATIENTS' SAFETY].

PubMed

Niv, Yaron

2018-04-01

In 1999 the Institute of Medicine (ION) declared that "to err in human" and that our goal is not to "blame and shame" but to investigate and establish processes that will prevent future mistakes. Shortage in manpower, physicians and nurses, may cause a disproportional burden of work and increase mistakes and adverse events. The complexity of patients requires a multidisciplinary team with many participants for achieving goals and saving lives. In the last 2 decades there was an exponential increase in the number of medical negligence claims and a similar increase in the sums given to the plaintiffs, in verdicts, mediation or compromises. The judges see before them the victims of these mistakes and their suffering, and look at the health system as a "deep pocket" for plaintiffs' compensation. Health institutes invest a lot of money and personnel to protect against claims instead of investing in systemic learning, manpower and equipment for preventing future adverse events. Fear of claims may cause excellent physicians to leave their profession leading to a possible shortage in experts in some important fields.

From lead to manganese through mercury: mythology, science, and lessons for prevention.

PubMed

Alessio, Lorenzo; Campagna, Marcello; Lucchini, Roberto

2007-11-01

Lead (Pb), mercury (Hg), and manganese (Mn) are well-known neurotoxic metals. The knowledge of toxicity was developed through an extensive amount of research, starting with lead and mercury and proceeding today with manganese. Unfortunately, the consequent implementation of preventive measures was generally delayed, causing important negative effects to the exposed populations. A review and historical reconstruction of the research development that yielded modern understanding of lead and mercury neurotoxicity was conducted to derive useful lessons for the prevention of manganese neurotoxicity. Medieval alchemists named planets and metals from gods since they were already aware of the toxicity and the adverse effects caused by lead and mercury. Historical lessons learned from these two metals may help to avoid the repetition of further mistakes regarding other neurotoxic metals like manganese. The knowledge and experience on the toxicokinetics and toxicodynamics of lead and mercury is useful and valuable to identify a proper approach to "safe" exposure levels for manganese. Further information is still needed on the early neurotoxic and neurobehavioral effects after prolonged exposure to very low doses of lead, mercury, and manganese. Nevertheless, according to the precautionary principle, effective preventive measures should be already undertaken to prevent the onset of more severe health effects in the population. This is the most important lesson to be learned and applied from more than 30 years of occupational and environmental neurotoxicology of metals. (c) 2007 Wiley-Liss, Inc.

Motivational processes from expectancy-value theory are associated with variability in the error positivity in young children.

Motivational beliefs and values influence how children approach challenging activities. The current study explored motivational processes from an expectancy-value theory framework by studying children's mistakes and their responses to them by focusing on two event-related potential (ERP) components: the error-related negativity (ERN) and the error positivity (Pe). Motivation was assessed using a child-friendly challenge puzzle task and a brief interview measure prior to ERP testing. Data from 50 4- to 6-year-old children revealed that greater perceived competence beliefs were related to a larger Pe, whereas stronger intrinsic task value beliefs were associated with a smaller Pe. Motivation was unrelated to the ERN. Individual differences in early motivational processes may reflect electrophysiological activity related to conscious error awareness.

Carmack, Heather J

2014-06-01

Physicians accept that they have an ethical responsibility to disclose and apologize for medical errors; however, when physicians make a medical error, they are often not given the opportunity to disclose and apologize for the mistake. In this article, I explore how one hospital negotiated the aftermath of medical mistakes through a disclosure and apology program. Specifically, I used Burke's cycle of redemption to position the hospital's disclosure and apology program as a redemption process and explore how the hospital physicians and administrators worked through the experiences of disclosing and apologizing for medical errors. © The Author(s) 2014.

Strengths, weaknesses, opportunities, and threats analysis of integrating the World Health Organization patient safety curriculum into undergraduate medical education in Pakistan: a qualitative case study

PubMed Central

2017-01-01

Purpose The purpose of this study was to conduct a strengths, weaknesses, opportunities, and threats (SWOT) analysis of integrating the World Health Organization (WHO) patient safety curriculum into undergraduate medical education in Pakistan. Methods A qualitative interpretive case study was conducted at Riphah International University, Islamabad, from October 2016 to June 2017. The study included 9 faculty members and 1 expert on patient safety. The interviews were audiotaped, and a thematic analysis of the transcripts was performed using NVivo software. Results Four themes were derived based on the need analysis model. The sub-themes derived from the collected data were arranged under the themes of strengths, weaknesses, opportunities, and threats, in accordance with the principles of SWOT analysis. The strengths identified were the need for a formal patient safety curriculum and its early integration into the undergraduate program. The weaknesses were faculty awareness and participation in development programs. The opportunities were an ongoing effort to develop an appropriate curriculum, to improve the current culture of healthcare, and to use the WHO curricular resource guide. The threats were attitudes towards patient safety in Pakistani culture, resistance to implementation from different levels, and the role of regulatory authorities. Conclusion The theme of patient safety needs to be incorporated early into the formal medical education curriculum, with the main goals of striving to do no harm and seeing mistakes as opportunities to learn. Faculty development activities need to be organized, and faculty members should to be encouraged to participate in them. The lack of a patient safety culture was identified as the primary reason for resistance to this initiative at many levels. The WHO curriculum, amended according to local institutional culture, can be implemented appropriately with support from the corresponding regulatory bodies. PMID:29284217

Is High Fidelity Simulation the Most Effective Method for the Development of Non-Technical Skills in Nursing? A Review of the Current Evidence

PubMed Central

Lewis, Robin; Strachan, Alasdair; Smith, Michelle McKenzie

2012-01-01

Aim: To review the literature on the use of simulation in the development of non-technical skills in nursing Background: The potential risks to patients associated with learning 'at the bedside' are becoming increasingly unacceptable, and the search for innovative education and training methods that do not expose the patient to preventable errors continues. All the evidence shows that a significant proportion of adverse events in health care is caused by problems relating to the application of the 'non-technical' skills of communication, teamwork, leadership and decision-making. Results: Simulation is positively associated with significantly improved interpersonal communication skills at patient handover, and it has also been clearly shown to improve team behaviours in a wide variety of clinical contexts and clinical personnel, associated with improved team performance in the management of crisis situations. It also enables the effective development of transferable, transformational leadership skills, and has also been demonstrated to improve students' critical thinking and clinical reasoning in complex care situations, and to aid in the development of students' self-efficacy and confidence in their own clinical abilities. Conclusion: High fidelity simulation is able to provide participants with a learning environment in which to develop non-technical skills, that is safe and controlled so that the participants are able to make mistakes, correct those mistakes in real time and learn from them, without fear of compromising patient safety. Participants in simulation are also able to rehearse the clinical management of rare, complex or crisis situations in a valid representation of clinical practice, before practising on patients.

The mouse that trolled: the long and tortuous history of a gene mutation patent that became an expensive impediment to Alzheimer's research

PubMed Central

Bubela, Tania; Vishnubhakat, Saurabh; Cook-Deegan, Robert

2015-01-01

This case study presents the tale of the academic discovery of a rare mutation for early-onset Alzheimer's disease that was patented by a sole inventor and licensed to a non-practicing entity (NPE), the Alzheimer's Institute of America (AIA). Our aims are (1) to relate this story about patents, research tools, and impediments to medical progress, and (2) to inform ongoing debates about how patents affect research, disposition of university inventions, and the distribution of benefits from publicly funded research. We present an account of the hunt for Alzheimer's genes, their patenting, assignment, and enforcement based on literature, litigation records and judicial decisions. While AIA's litigation eventually failed, its suits against 18 defendants, including one university, one foundation, and three non-profit organizations were costly in court years, legal fees, and expert time. Reasons for the failure included non-disclosure of co-inventors, State laws on ownership and assignment of university inventions, and enablement. We discuss the policy implications of the litigation, questioning the value of patents in the research ecosystem and the role of NPEs (“patent trolls”) in biotechnological innovation. The case illustrates tactics that may be deployed against NPEs, including, avenues to invalidate patent claims, Authorization and Consent, legislative reforms specifically targeting NPEs, reforms in the America Invents Act, and judicial action and rules for judicial proceedings. In the highly competitive research environment of Alzheimer's genetics in the 1990s, patents played a minor, subordinate role in spurring innovation. The case produces a mixed message about the patent system. It illustrates many mistakes in how patents were obtained, administered, and enforced, but, eventually, the legal system rectified these mistakes, albeit slowly, laboriously, and at great cost.

2015-01-01

Aim: Every year, millions of people around the world suffer from different infectious diseases, considerable part of which are hospital-acquired infections. WHO considers hand hygiene as a priority measure aimed to reduce the level of infection. We evaluated various aspects related to the situational behavior and prioritization regarding hand hygiene measures among the healthcare workers of Ukraine. Method: Identification of system mistakes in hand hygiene was carried out first of all by direct and indirect observation of the activities of medical and pharmaceutical personnel in their everyday practice as well as during their participation in trainings on routine hand hygiene. Questionnaires also were used to estimate the level of hand hygiene compliance of participants of the study. During this period 112 training courses, 315 master-classes and presentations on proper hand hygiene were realized. The target audience included health care workers of medical centers, clinics, maternity hospitals, health care organizations and staff of pharmacies and pharmaceutical manufacturing enterprises in all regions of Ukraine. 638 respondents took part in anonymous survey on hand hygiene practice. Results: The most common mistakes were to regard hand washing and hand disinfection equally, to wash hands before doing a hand disinfection, to neglect the five moments for hand hygiene and to ignore hand hygiene before and after wearing protective gloves. Practitioners, medical attendants, pharmacy and pharmaceutical industry workers highlighted the need for practical and understandable instructions of various hand hygiene procedures, including the clarification of the possible technical mistakes. This became a ground for us to create individual master classes on hand hygiene for each cluster of healthcare workers. Conclusions: Changing hand hygiene behavior and attitude is possible by beginning to observe clinical practice and by involving healthcare workers in teaching and training. PMID:25699224

A Morally Permissible Moral Mistake? Reinterpreting a Thought Experiment as Proof of Concept.

PubMed

Emmerich, Nathan; Gordjin, Bert

2018-03-07

This paper takes the philosophical notion of suberogatory acts or morally permissible moral mistakes and, via a reinterpretation of a thought experiment from the medical ethics literature, offers an initial demonstration of their relevance to the field of medical ethics. That is, at least in regards to this case, we demonstrate that the concept of morally permissible moral mistakes has a bearing on medical decision-making. We therefore suggest that these concepts may have broader importance for the discourse on medical ethics and should receive fuller consideration by those working the field. The focus of the discussion we present is on a particular thought experiment originally presented by Sulmasy and Sugarman. Their case formed the basis of an exchange about the moral equivalence of withdrawing and withholding life-saving treatment. The analysis Sulmasy and Sugarman set out is significant because, contrary to common bioethical opinion, it implies that the difference between withdrawing and withholding life-saving treatment holds, rather than lacks, moral significance. Following a brief discussion of rejoinders to Sulmasy and Sugarman's article, we present a constructive reinterpretation of the thought experiment, one that draws on the idea of suberogatory acts or "morally permissible moral mistakes." Our analysis, or so we suggest, accounts for the differing moral intuitions that the case prompts. However, it also calls into question the degree to which this thought experiment can be thought of as illustrating the moral (non)equivalence of withdrawing and withholding life-saving treatment. Rather, we conclude that it primarily illuminates something about the ethical parameters of healthcare when family members, particularly parents, are involved in decision-making.

Note on: 'EMLCLLER-A program for computing the EM response of a large loop source over a layered earth model' by N.P. Singh and T. Mogi, Computers & Geosciences 29 (2003) 1301-1307

NASA Astrophysics Data System (ADS)

Jamie, Majid

2016-11-01

Singh and Mogi (2003) presented a forward modeling (FWD) program, coded in FORTRAN 77 called "EMLCLLER", which is capable of computing the frequency-domain electromagnetic (EM) response of a large circular loop, in terms of vertical magnetic component (Hz), over 1D layer earth models; computations at this program could be performed by assuming variable transmitter-receiver configurations and incorporating both conduction and displacement currents into computations. Integral equations at this program are computed through digital linear filters based on the Hankel transforms together with analytic solutions based on hyper-geometric functions. Despite capabilities of EMLCLLER, there are some mistakes at this program that make its FWD results unreliable. The mistakes in EMLCLLER arise in using wrong algorithm for computing reflection coefficient of the EM wave in TE-mode (rTE), and using flawed algorithms for computing phase and normalized phase values relating to Hz; in this paper corrected form of these mistakes are presented. Moreover, in order to illustrate how these mistakes can affect FWD results, EMLCLLER and corrected version of this program presented in this paper titled "EMLCLLER_Corr" are conducted on different two- and three-layered earth models; afterwards their FWD results in terms of real and imaginary parts of Hz, its normalized amplitude, and the corresponding normalized phase curves are plotted versus frequency and compared to each other. In addition, in Singh and Mogi (2003) extra derivations for computing radial component of the magnetic field (Hr) and angular component of the electric field (Eϕ) are also presented where the numerical solution presented for Hr is incorrect; in this paper the correct numerical solution for this derivation is also presented.

Mistakes in ultrasound examination of salivary glands

PubMed Central

Jakubowski, Wiesław

2016-01-01

Ultrasonography is the first imaging method applied in the case of diseases of the salivary glands. The article discusses basic mistakes that can be made during an ultrasound examination of these structures. The reasons for these mistakes may be examiner-dependent or may be beyond their control. The latter may include, inter alia, difficult conditions during examination (technical or patient-related), similarity of ultrasound images in different diseases, the lack of clinical and laboratory data as well as the lack of results of other examinations, their insufficient number or incorrectness. Doctor-related mistakes include: the lack of knowledge of normal anatomy, characteristics of ultrasound images in various salivary gland diseases and statistical incidence of diseases, but also attaching excessive importance to such statistical data. The complex anatomical structures of the floor of the oral cavity may be mistaken for benign or malignant tumors. Fragments of correct anatomical structures (bones, arterial wall fibrosis, air bubbles in the mouth) can be wrongly interpreted as deposits in the salivary gland or in its excretory duct. Correct lymph nodes in the parotid glands may be treated as pathologic structures. Lesions not being a simple cyst, e.g. lymphoma, benign or malignant tumors of the salivary glands or metastatic lymph nodes, can be mistaken for one. The image of disseminated focal changes, both anechoic and solid, is not pathognomonic for specific diseases in the salivary glands. However, in part, it occurs typically and requires an extended differential diagnosis. Small focal changes and infiltrative lesions pose a diagnostic problem because their etiology cannot be safely suggested on the basis of an ultrasound examination itself. The safest approach is to refer patients with abnormal focal changes for an ultrasoundguided fine-needle aspiration biopsy. PMID:27446603

This study aims to determine the types and causes of errors, as well as efforts being attempted to overcome the mistakes made by junior high school students in completing PISA content space and shape. Two subjects were selected based on the mathematical ability test results with the most error, yet they are able to communicate orally and in writing. Two selected subjects then worked on the PISA ability test question and the subjects were interviewed to find out the type and cause of the error and then given a scaffolding based on the type of mistake made.The results of this study obtained the type of error that students do are comprehension and transformation error. The reasons are students was not able to identify the keywords in the question, write down what is known or given, specify formulas or device a plan. To overcome this error, students were given scaffolding. Scaffolding that given to overcome misunderstandings were reviewing and restructuring. While to overcome the transformation error, scaffolding given were reviewing, restructuring, explaining and developing representational tools. Teachers are advised to use scaffolding to resolve errors so that the students are able to avoid these errors.

Epigenetic Mistakes in Neurodevelopmental Disorders.

Epigenetics is the array of the chromatin modifications that customize in cell-, stage-, or condition-specific manner the information encloses in plain DNA molecules. Increasing evidences suggest the importance of epigenetic mechanisms for development and maintenance of central nervous system. In fact, a large number of newly discovered genetic causes of neurodevelopmental disorders such as intellectual disability, autism spectrum disorders, and many other syndromes are mutations within genes encoding for chromatin remodeling enzymes. Here, we review recent findings on the epigenetic origin of human diseases, with emphasis on disorders that affect development of the nervous system, and discuss novel therapeutic avenues that target epigenetic mechanisms.

The present case is one of a patient suffering from traumatic neurosis, on whom psychotherapeutic work has been possible. The traumatic experience, which dates back to the Franco-Algerian War, could have gradually started making sense in the context of its onset and of the state in which the relationship between the patient and his father remained at the time. Something along the lines of an irrevocable mistake, irrevocable since logically referred to as a serious moral mistake on the part of the father towards his son, renders humanely comprehensible his upkeep of his atrocity as represented by the repetition of the revival symptoms.

Medical negligence--prevention and management.

The rising spate of malpractice cases against doctors appearing in the press and annual reports of medical insurance companies causes concern. Are our doctors more careless or is the public more conscious of litigation? A well publicized malpractice case can ruin the doctor's career and practice. It is well worth a doctor's while to know the pitfalls and learn how to prevent them, and if a mistake happens, how to manage it. Not all mistakes amount to negligence. How will the court view these cases? Some local cases are cited to illustrate the difference between misadventure and negligence. They will serve as guidelines for good medical practice.

Problem of Mistakes in Databases, Processing and Interpretation of Observations of the Sun. I.

Lozitska, N. I.

In databases of observations unnoticed mistakes and misprints could occur at any stage of observation, preparation and processing of databases. The current detection of errors is complicated by the fact that the works of observer, databases compiler and researcher were divided. Data acquisition from a spacecraft requires the greater amount of researchers than for ground-based observations. As a result, the probability of errors is increasing. Keeping track of the errors on each stage is very difficult, so we use of cross-comparison of data from different sources. We revealed some misprints in the typographic and digital results of sunspot group area measurements.

The analysis by Haggbloom, et al. (2002) establishing a list of the most eminent psychologists of the 20th century contains significant errors. In one case the achievements of Walter B. Cannon are misattributed to W. Gary Cannon. Other errors are eponyms misattributed to Margaret F. Washburn, Morton Deutsch, Wolfgang Köhler, and G. Stanley Hall. A further mistake is to miscalculate the statistic for introductory psychology textbook citations for Hans J. Eysenck. These errors have consequences for the ranking of individuals on this list. Care must be taken to guard against such mistakes.

Seven common mistakes in population genetics and how to avoid them.

PubMed

Meirmans, Patrick G

2015-07-01

As the data resulting from modern genotyping tools are astoundingly complex, genotyping studies require great care in the sampling design, genotyping, data analysis and interpretation. Such care is necessary because, with data sets containing thousands of loci, small biases can easily become strongly significant patterns. Such biases may already be present in routine tasks that are present in almost every genotyping study. Here, I discuss seven common mistakes that can be frequently encountered in the genotyping literature: (i) giving more attention to genotyping than to sampling, (ii) failing to perform or report experimental randomization in the laboratory, (iii) equating geopolitical borders with biological borders, (iv) testing significance of clustering output, (v) misinterpreting Mantel's r statistic, (vi) only interpreting a single value of k and (vii) forgetting that only a small portion of the genome will be associated with climate. For every of those issues, I give some suggestions how to avoid the mistake. Overall, I argue that genotyping studies would benefit from establishing a more rigorous experimental design, involving proper sampling design, randomization and better distinction of a priori hypotheses and exploratory analyses. © 2015 John Wiley & Sons Ltd.

In response to increasingly complex demands in terms of productivity and budgets, there is a critical need to avoid mistakes during instrument selection that will be financially costly, and adversely affect customers, staff, productivity and test turnaround time. As there is no "one size fits all", guidelines must be appropriate to permit informed decision making. A Medline search was conducted to assess background knowledge in this area, using the terms "laboratory instrument selection" and "laboratory instrument evaluation". Searches returned over 800 articles, of which only seven were directly related to the topic of the search, with most outdated, and suggesting a paucity of appropriate information. Additional resources used included the American Association of Clinical Chemistry (AACC) website and the Internet. Appropriate criteria for instrument selection were established in the current report based on subjective and objective (technical) evaluations. Additionally, a sound and simple financial approach is also suggested to help in making informed decisions and avoid costly mistakes. We propose that such a process as outlined in our report will protect laboratories from making costly and avoidable mistakes in the acquisition of major equipment.

[Impairment of safety in navigation caused by alcohol: impact on visual function].

So far in Germany, no legally binding standards for blood alcohol concentration exist that prove an impairment of navigability. The aim of our interdisciplinary project was to obtain data in order to identify critical blood alcohol limits. In this context the visual system seems to be of decisive importance. 21 professional skippers underwent realistic navigational demands soberly and alcoholized in a sea traffic simulator. The following parameters were considered: visual acuity, stereopsis, color vision, and accommodation. Under the influence of alcohol (average blood alcohol concentration: 1.08 per thousand ) each skipper considered himself to be completely capable of navigating. While simulations were running, all of the skippers made nautical mistakes or underestimated dangerous situations. Severe impairment in visual acuity or binocular function were not observed. Accommodation decreased by an average of 18% ( p=0.0001). In the test of color vision skippers made more mistakes ( p=0.017) and the time needed for this test was prolonged ( p=0.004). Changes in visual function as well as vegetative and psychological reactions could be the cause of mistakes and alcohol should therefore be regarded as a severe risk factor for security in sea navigation.

We aimed in this study to determine any mistakes or omissions made while preparing judicial reports, which contribute to the judicial process. In this study, we evaluated as samples 351 judicial reports of victims who applied to the Emergency Service of Ondokuz Mayis University between January 1, 2005 and December 31, 2005 with respect to the judicial facts, and we recorded any mistakes or omissions of data in these reports. We determined that there was no record of age in 6% of the judicial reports, of examination time in 71.8%, of traumatic lesion or not in 30.5%, of the state of consciousness in 58.7%, and of the presence or not of life-threatening risks in 2.6%. The name of the physician who prepared the report was not provided in 8.0% of the reports. The most important omission is that none of the reports had the name, surname or signature of the person who had taken the prepared report. We concluded that, after graduation, it is necessary for physicians, who are responsible for both treating the patients and writing judicial reports, to attend in-service training programs. They must also be properly advised regarding their responsibilities in judicial cases.

Stahl, H. Philip

2014-01-01

Based on 30 years of optical testing experience, a lot of mistakes, a lot of learning and a lot of experience, I have defined seven guiding principles for optical testing - regardless of how small or how large the optical testing or metrology task: Fully Understand the Task, Develop an Error Budget, Continuous Metrology Coverage, Know where you are, Test like you fly, Independent Cross-Checks, Understand All Anomalies. These rules have been applied with great success to the inprocess optical testing and final specification compliance testing of the JWST mirrors.

Adolescent pregnancy and parenting: controversies of the past and lessons for the future.

PubMed

Klerman, L V

1993-11-01

Recent research findings suggest that old ways of looking at adolescent sexuality, pregnancy, and parenting should be revised and that new approaches to service programs should be developed. This paper presents some new facts by examining the validity of nine beliefs about adolescent pregnancy: that nothing can reduce the rate of adolescent pregnancy; that pregnant adolescents experience poor pregnancy outcomes; that adolescent mothers do not complete their high school education; that pregnant adolescents have large families; that adolescent mothers remain on welfare for long periods; that pregnancy in adolescence is a mistake and, given a chance to overcome the immediate problems associated with it, young mothers can go on to lead normal lives; that welfare causes adolescent pregnancy and parenting; that adolescent mothers are poor parents; and that service programs can have a significant impact on adolescent pregnancy and parenting. Although programs aimed at the prevention and amelioration of the problems experienced by pregnant adolescents, young mothers, and their children and families have shown some success, relatively few are sufficiently powerful to bring about major changes--and even these are infrequently replicated because of high costs. Further progress in this area depends not only on new and expanded programs, but also on attacking the problem of poverty, which is an underlying cause of early sexual activity and childbearing.

What is a species? Essences and generation.

PubMed

Wilkins, John S

2010-09-01

Arguments against essentialism in biology rely strongly on a claim that modern biology abandoned Aristotle's notion of a species as a class of necessary and sufficient properties. However, neither his theory of essentialism, nor his logical definition of species and genus (eidos and genos) play much of a role in biological research and taxonomy, including his own. The objections to natural kinds thinking by early twentieth century biologists wrestling with the new genetics overlooked the fact that species have typical developmental cycles and most have a large shared genetic component. These are the "what-it-is-to-be" members of that species. An intrinsic biological essentialism does not commit us to Aristotelian notions, nor even modern notions, of essence. There is a long-standing definition of "species" and its precursor notions that goes back to the Greeks, and which Darwin and pretty well all biologists since him share, that I call the Generative Conception of Species. It relies on there being a shared generative power that makes progeny resemble parents. The "what-it-is-to-be" a member of that species is that developmental type, mistakes in development notwithstanding. Moreover, such "essences" have always been understood to include deviations from the type. Finally, I shall examine some implications of the collapse of the narrative about essences in biology.

["Psychologus nemo, nisi Physiologus"--Johannes Müller and perspectives of médecine philosophique: a discovery from University's Archive].

PubMed

Scharbert, Gerhard

2010-01-01

Taking Johannes Müller's still little examined school education in then French Koblenz at its starting point, this paper argues that Miiller's pre-academic training in the applied sciences as well as in the old languages--which Müller saw as a basic essential for the philosophically educated naturalist--had a profound impact on the scientific-philosophical views he put forward in his Dissertatio inauguralis physiologica sistens commentarios de phoronomia animalium published in 1822. The Dissertatio was influenced, in particular, by the work of Pierre-Jean-Georges Cabanis (1757-1808) and can be read as a physiological application of French Enlightenment sensualist philosophy. It shows that Müller already at early moment took up decisive impulses from revolutionary France. Also, a traditional mistake is shown to have falsified a fundamental aspect of this earliest work already with lasting effect.

Herbological studies of Coptidis rhizoma (Part 2): on the old Japanese name of Coptis japonica makino.

The rhizome of Coptis plant of the family ranunculaceae has been used in traditional Chinese medicine as a crude drug (Huanglian in present Chinese). In Japan, the rhizome of Coptis japonica Makino (the botanical name of which is "Ohren" in modern Japanese) has been utilized as a crude drug since the Nara era. The Japanese name in those days was "Kakumakusa based on descriptions in old books written in the Heian era. It changed to "Kakumikusa" early in the Edo era, and then changed again to Kakumakusa later in the Edo era. Through this herbological study, it was conjectured as follows: The resemblance between Chinese characters (or MA) and (or MI) in cursive style caused mis-copying of the character. After the "Honzo-wamyo, written in the Heian era, was revised in the late Edo era, and on which the name was accurately written as Kakumakusa, the mistake was corrected.

The Rat Model in Microsurgery Education: Classical Exercises and New Horizons

2014-01-01

Microsurgery is a precise surgical skill that requires an extensive training period and the supervision of expert instructors. The classical training schemes in microsurgery have started with multiday experimental courses on the rat model. These courses have offered a low threat supervised high fidelity laboratory setting in which students can steadily and rapidly progress. This simulated environment allows students to make and recognise mistakes in microsurgery techniques and thus shifts any related risks of the early training period from the operating room to the lab. To achieve a high level of skill acquisition before beginning clinical practice, students are trained on a comprehensive set of exercises the rat model can uniquely provide, with progressive complexity as competency improves. This paper presents the utility of the classical rat model in three of the earliest microsurgery training centres and the new prospects that this versatile and expansive training model offers.

Perceptual representation, veridicality, and the interface theory of perception.

PubMed

Cohen, Jonathan

2015-12-01

Hoffman, Singh, and Prakash (henceforth, HSP) argue that perception was not selected for veridical representation, hence that, contrary to a very widespread consensus, there's much less of the latter than you might expect in perception. And they put forward an alternative "interface" theory, on which perception is an adaptively useful but truth-obscuring veil between perceiver and perceived. But HSP's case against veridical perception, and their case for an alternative account, turn crucially on significant misapprehensions in the early going about what veridicality amounts to. In this paper I'll identify this mistake, and then argue that it both undercuts HSP's arguments against perceptual veridicality and prevents them from seeing that their own preferred conception of perception is itself committed to veridical representation, rather than an alternative to it. In the end, I'll conclude, HSP give us no reasons to abandon the standard view that perception veridically represents the world.

In this paper we will prove that the Lorentz factor doesn't exist on the relative motion. In fact this factor is the result of a wrong calculation of Michelson. His mistake was approved by Lorentz and other physicists, including Einstein. Michelson in order to implement his idea with his interferometer in 1881, made the following mistake: he made the calculation according to the only principle of relativity which was known by physics--the Galileo principle, but he didn't faithfully apply this principle. In this paper, the principle of Galileo will be implemented exactly to Michelson's experiment and the result will showmore » us that physics doesn't need the postulates of the year 1905.« less

This report relates how tracurium was given by mistake, intrathecally, during spinal anesthesia, to a 38-year-old woman, who was a candidate for abdominal hysterectomy. When no analgesia was observed, the mistake in giving the injection was understood. She was evaluated postoperatively by train of four ratio, measuring her breathing rate, eye opening, and protruding of tongue at one, two, twenty-four, and forty-eight hours, and then at one and two weeks, with the final evaluation the following month. The patient had normal timings during the operation and postoperation periods, and no abnormal findings were observed through the first month. This finding was contrary to several studies, which described adverse reactions due to accidental intrathecal injection of neuromuscular blocking drugs.

Misconceptions of positivism and five unnecessary science theoretic mistakes they bring in their train.

Persson, Johannes

2010-05-01

Positivism is sometimes rejected for the wrong reasons. Influential textbooks on nursing research and in other disciplines tend to reinforce the misconceptions underlying these rejections. This is problematic, since it provides students of these disciplines with a poor basis for reflecting on epistemological and methodological perspectives. It is particularly common for positivist views on reality and causation to be obscured. The first part of this discussion paper identifies and explains the misconceptions about positivism as they appear in two influential textbooks. The second part pinpoints five mistakes these misconceptions easily result in when the researcher adopts an epistemological and methodological standpoint. Copyright 2009 Elsevier Ltd.

Psychophysiology of Spaceflight and Aviation

Cowings, Patricia; Toscano, William

2013-01-01

In space, the absence of gravity alone causes unique physiological stress. Significant biomedical changes, across multiple organ systems, such as body fluid redistribution, diminished musculoskeletal strength, changes in cardiac function and sensorimotor control have been reported. The time course of development of these disorders and severity of symptoms experienced by individuals varies widely. Space motion sickness (SMS) is an example of maladaptation to microgravity, which occurs early in the mission and can have profound effects on physical health and crew performance. Disturbances in sleep quality, perception, emotional equilibrium and mood have also been reported, with impact to health and performance varying widely across individuals. And lastly, post-flight orthostatic intolerance, low blood pressure experienced after returning to Earth, is also of serious concern. Both the Russian and American space programs have a varied list of human errors and mistakes, which adversely impacted mission goals. Continued probability of human exposure to microgravity for extended time periods provides a rationale for the study of the effects of stress. The primary focus of this research group is directed toward examining individual differences in: (a) prediction of susceptibility to these disorders, (b) assessment of symptom severity, (c) evaluation of the effectiveness of countermeasures, and (d) developing and testing a physiological training method, Autogenic-Feedback Training Exercise (AFTE) as a countermeasure with multiple applications. The present paper reports on the results of a series of human flight experiments with AFTE aboard the Space Shuttle and Mir Space Station, and during emergency flight scenarios on Earth.

Exploring Spanish health social media for detecting drug effects

PubMed Central

2015-01-01

Background Adverse Drug reactions (ADR) cause a high number of deaths among hospitalized patients in developed countries. Major drug agencies have devoted a great interest in the early detection of ADRs due to their high incidence and increasing health care costs. Reporting systems are available in order for both healthcare professionals and patients to alert about possible ADRs. However, several studies have shown that these adverse events are underestimated. Our hypothesis is that health social networks could be a significant information source for the early detection of ADRs as well as of new drug indications. Methods In this work we present a system for detecting drug effects (which include both adverse drug reactions as well as drug indications) from user posts extracted from a Spanish health forum. Texts were processed using MeaningCloud, a multilingual text analysis engine, to identify drugs and effects. In addition, we developed the first Spanish database storing drugs as well as their effects automatically built from drug package inserts gathered from online websites. We then applied a distant-supervision method using the database on a collection of 84,000 messages in order to extract the relations between drugs and their effects. To classify the relation instances, we used a kernel method based only on shallow linguistic information of the sentences. Results Regarding Relation Extraction of drugs and their effects, the distant supervision approach achieved a recall of 0.59 and a precision of 0.48. Conclusions The task of extracting relations between drugs and their effects from social media is a complex challenge due to the characteristics of social media texts. These texts, typically posts or tweets, usually contain many grammatical errors and spelling mistakes. Moreover, patients use lay terminology to refer to diseases, symptoms and indications that is not usually included in lexical resources in languages other than English. PMID:26100267

A method for the analysis of fatigue parameters has been rarely researched in VDT operation. Up to now, fatigue was evaluated by changing of biological information. If signals regarding fatigue are detected, fatigue can be measured. The purpose of this study proposed experiment and analysis method to extract parameters related to fatigue from the biological information during VDT operation using the Independent Component Analysis (ICA). An experiment had 11 subjects. As for the experiment were light loaded VDT operation and heavy loaded VDT operation. A measurement item were amount of work, a mistake number, subjective symptom, surface skin temperature (forehead and apex nasi), heart rate, skin blood flow of forearm and respiratory rate. In the heavy loaded operation group, mistake number and subjective symptom score were increased to compare with the other. And Two-factor ANOVA was used for analysis. The result of mistake number was confirmed that heavy loaded. After the moving averages of waveshape were calculated, it was made to extract independent components by using the ICA. The results of the ICA suggest that the independent components increase according to accumulation of fatigue. Thus, the independent components would be a possible parameter of fatigue. However, further experiments should continue in order to obtain the conclusive finding of our research.

[A qualitative analysis of spelling mistakes and a systematic supportive learning instruction of spelling disorder].

This paper explains how a qualitative analysis of spelling mistakes (Oldenburger Fehleranalyse, Thomé & Thomé, 2014) may be used to select learning materials according to individual needs. The pre-post design with control group serves to evaluate the effects of an intervention that is systematic and learning supportive for pupils with a diagnosed spelling disorder (ages 12 to 14; 6th-8th grade). Therapists of the experimental group were instructed to apply a series of linguistic and psycholinguistic criteria when creating the material for instruction and when carrying out the therapy. Therapists of the control group carried out the intervention without attending to these criteria, although they did have knowledge about the pupil’s profile in spelling mistakes. The intervention included 20 sessions. The ANOVA shows improvement for both groups (HSP, May 2012): (F(1, 14) = 15,05, p = .002, η2 = .518). For the experimental group it is stronger, and the difference in achievement gain is significant (F(1, 14) = 4,70, p = .048; η2 = .25). These results support a combination of qualitative analysis and a high qualification for therapists that relates specifically to orthography and its instruction. For some pupils the changes in the qualitative profiles reveal persistent support requirements in phonology or grammar instruction.

Tolerance of ambiguity, perfectionism and resilience are associated with personality profiles of medical students oriented to rural practice.

Resilience, coping with uncertainty and learning from mistakes are vital characteristics for all medical disciplines - particularly rural practice. Levels of coping constructs were examined in medical students with and without a rural background or an interest in rural practice. Cross-sectional surveys identified two personality profiles, and their association with levels of Tolerance of Ambiguity, Resilience, Perfectionism-High Standards and Concern over mistakes as constructs indicative of coping. Medical students (N = 797) were stratified by rural background and degree of rural interest. Mediation analysis tested the effect of personality profile on levels of the coping constructs. More (72%) rural background students had Profile 1 which was associated with higher levels of Tolerance of Ambiguity, High standards, and Resilience, but lower Concern over mistakes. Non-rural background students reporting a strong rural interest also had Profile 1 (64%) and similar levels of coping constructs. Personality profile mediated the association between rural interest and levels of coping constructs regardless of background. Having a rural background or strong rural interest are associated with a personality profile that indicates a better capacity for coping. Personality may play a part in an individual's interest in rural practice. Rural workforce initiatives through education should encourage and nurture students with a genuine interest in rural practice - regardless of background.

Fiber-handling robot and optical connection mechanisms for automatic cross-connection of multiple optical connectors

Mizukami, Masato; Makihara, Mitsuhiro

2013-07-01

Conventionally, in intelligent buildings in a metropolitan area network and in small-scale facilities in the optical access network, optical connectors are joined manually using an optical connection board and a patch panel. In this manual connection approach, mistakes occur due to discrepancies between the actual physical settings of the connections and their management because these processes are independent. Moreover, manual cross-connection is time-consuming and expensive because maintenance personnel must be dispatched to remote places to correct mistakes. We have developed a fiber-handling robot and optical connection mechanisms for automatic cross-connection of multiple optical connectors, which are the key elements of automatic optical fiber cross-connect equipment. We evaluate the performance of the equipment, such as its optical characteristics and environmental specifications. We also devise new optical connection mechanisms that enable the automated optical fiber cross-connect module to handle and connect angled physical contact (APC) optical connector plugs. We evaluate the performance of the equipment, such as its optical characteristics. The evaluation results confirm that the automated optical fiber cross-connect equipment can connect APC connectors with low loss and high return loss, indicating that the automated optical fiber cross-connect equipment is suitable for practical use in intelligent buildings and optical access networks.

Incorrect electrode cable connection during electrocardiographic recording.

Batchvarov, Velislav N; Malik, Marek; Camm, A John

2007-11-01

Incorrect electrode cable connections during electrocardiographic (ECG) recording can simulate rhythm or conduction disturbance, myocardial ischaemia and infarction, as well as other clinically important abnormalities. When only precordial or only limb cables, excluding the neutral cable, have been interchanged the waveforms in the different leads are re-arranged, inverted, or unchanged, whereas the duration of intervals is not changed. The mistake can be recognized by the presence of unusual P-QRS patterns (e.g. negative P-QRS in lead I or II, positive in lead AVR, P-QRS complexes of opposite direction in leads I and V6, etc.), change in the P-QRS axis, or abnormal precordial QRS-T wave progression. Interchange of limb cables with the neutral cable distorts Wilson's terminal and the morphology of all precordial and unipolar limb leads. The telltale sign of the mistake is the presence of (almost) a flat line in lead I, II or III. Interchange of even one of the limb cables, except for the neutral cable, with a precordial cable distorts the morphology of most leads and leaves not more than one lead (I, II, or III) unchanged. Computerized algorithms for detection of lead misplacement, such as those based on artificial neural networks, or on correlation between original and reconstructed leads, have been developed.

Deficits in fine motor coordination have been suggested to be associated with Attention-Deficit/Hyperactivity Disorder (ADHD). However, despite the negative impact of poor fine motor skills on academic achievement, researchers have paid little attention to this problem. The aim of this study was to explore the relationship between ADHD dimensions and fine motor performance. Participants were 43 children with a diagnosis of ADHD aged between 7 and 14 years (M=9.61; 81% male) and 42 typically developing (TP) children in the same age range (M=10.76; 75.2% male). Children with ADHD performed worse than TP on all tasks (δ Fine_motor_tasks, -0.19 to -0.44). After controlling for age and ADHD-HY (hyperactivity/impulsivity), higher scores on ADHD-IN (inattentiveness) predicted a larger number of mistakes among all psychomotricity tasks and conditions (β 0.39-0.58, ps<0.05). The ADHD group showed poorer fine motor performance than controls across all fine motor coordination tasks. However, lower performance (more mistakes), was related to the inattention dimension but not to the hyperactivity/impulsivity dimensions. Authors recommend including training and enhancement of the fine motor skills for more comprehensive ADHD treatment. Copyright © 2017 Elsevier Ltd. All rights reserved.

This review focuses on the potential role of soft drinks, particularly the sugar component, in the pathogenesis of erectile dysfunction (ED). We analyzed the hypothetical link between metabolic disorders, induced by sweetened soft drinks overconsumption, and ED. High caloric intake, high refined-carbohydrates, and high fructose corn syrup (HFCS) content and less satiety are main factors responsible for metabolic disorders contributing to ED development. Regular diet mistakes among human males, such as soft drink consumption, may lead to slow and asymptomatic progression of ED, finally resulting in full claimed manifestation of ED.

The Framework Programmable Software Development Platform (FPP) is a project aimed at combining effective tool and data integration mechanisms with a model of the software development process in an intelligent integrated software environment. Guided by the model, this system development framework will take advantage of an integrated operating environment to automate effectively the management of the software development process so that costly mistakes during the development phase can be eliminated. The focus here is on the design of components that make up the FPP. These components serve as supporting systems for the Integration Mechanism and the Framework Processor and provide the 'glue' that ties the FPP together. Also discussed are the components that allow the platform to operate in a distributed, heterogeneous environment and to manage the development and evolution of software system artifacts.

2017-05-19

We investigated the impact of messages about the causes of obesity (controllable or uncontrollable) on the disciplinary action consequences selected for obese employees in response to a work-related mistake. Participants read about either the controllable or uncontrollable causes of obesity before reviewing an ostensible employee file that included a description of an employee mistake. Depending on condition, the file contained a photo of the employee that either depicted them as obese or average weight. Participants were more willing to withhold a raise or promotion from an obese employee than from an average-weight employee. Further, there was little evidence that the messages about the causes of obesity affected participants' perceived control and self-efficacy for healthy behaviors.

In addition, the particle flux data from Spring II (30 m and 60 m) and Spring III (20 m) were standardized twice to deployment time, instead of to the deployment time and the sediment trap opening. These mistakes do not affect our conclusions, but we would like to present here the correct numbers for the result section 3.4, discussion section 4.3 and a revised Fig. 5.

Despite the popularity of prefabricated housing construction in Thailand and many other countries, due to the lack of collaboration in current practice, undesired low productivity and a number of mistakes are identified. This research proposes a framework to raise the collaborative level for improving productivity and reducing mistake occurrences at sites. In this framework, RFID system bridges the gap between the real situation and the design, and the proposed system can cope with the unexpected construction conditions by generating proper alternatives. This system is composed of PDAs, RFID readers, laptop PCs, and a desktop PC. Six main modules and a database system are implemented in laptop PCs for recording actual site conditions, generating working alternatives, providing related information, and evaluating the work.

Injection of botulinum toxin is currently the most common cosmetic procedure in the United States, and in recent years it has become-together with dermal fillers-the mainstay of therapy for the prevention and treatment of facial aging. However, in some cases the treatment may lead to a somewhat unnatural appearance, usually caused by loss of facial expression or other telltale signs. In the present article, we review the 10 mistakes that should be avoided when injecting botulinum toxin. We also reflect on how treatment with botulinum toxin influences us through our facial expressions, both in terms of how we feel and what others perceive.

Haerkens, Marck Htm; Jenkins, Donald H; van der Hoeven, Johannes G

2012-08-22

Intensive care frequently results in unintentional harm to patients and statistics don't seem to improve. The ICU environment is especially unforgiving for mistakes due to the multidisciplinary, time-critical nature of care and vulnerability of the patients. Human factors account for the majority of adverse events and a sound safety climate is therefore essential. This article reviews the existing literature on aviation-derived training called Crew Resource Management (CRM) and discusses its application in critical care medicine. CRM focuses on teamwork, threat and error management and blame free discussion of human mistakes. Though evidence is still scarce, the authors consider CRM to be a promising tool for culture change in the ICU setting, if supported by leadership and well-designed follow-up.

Practice improvement plans are required to prevent low-probability-high-consequence anesthesia mishaps in our offices. A scarcity of statistical data exists regarding the true risk of office-based anesthesia in oral and maxillofacial surgery. Effective proactive risk management mandates accurate data to correctly outline the problem before solutions can be implemented. Only by learning from our mistakes, will we be able to reduce errors and improve patient safety: "The only real mistake is the one from which we learn nothing"--John Powell.

Individual and organizational predictors of depression in general practitioners.

PubMed

Firth-Cozens, J

1998-10-01

High levels of stress and depression are seen in both general practitioners (GPs) and hospital doctors, and this has implications for patient care. It is therefore important to discover the individual and organizational causes of elevated symptoms so they can be tackled. To discover the relative importance of individual characteristics measured 10 years earlier compared with current organizational stressors in predicting depression in GPs. Longitudinal questionnaire study, using data from those of the original cohort of 318 medical students who are now GPs (n = 131), considering perceptions of current stressors and comparing through regression analyses the relative strength of early personality and mood with current organizational factors of sleep, hours worked, and practice size in predicting current depression levels. There were 22 (17%) stressors scoring above threshold for depression. Relationships with senior doctors and patients are the main reported stressors, followed by making mistakes and conflict of career with personal life. The predictors of symptom levels varied for men and women. In men, depression and self-criticism as students, and current sleep levels; and in women, sibling rivalry and current alcohol use, were the main predictors: in men, 27% of the variance was accounted for by early dispositional factors alone compared with 14% in women. A model is suggested linking sleep loss with workplace stressors, self-critical cognitions, and depression. Interventions can be made throughout training, targeting self-criticism and recognizing early depression, while later addressing the organizational stressors, particularly work relationships and sleep patterns.

Increasing Impact of Coursework Through Deep Analytics

Over the past few years, ASU has developed the online astrobiology lab course Habitable Worlds, which has been offered to over 1,500 students over seven semesters. The course is offered through Smart Sparrow's intelligent tutoring system, which records student answers, time on question, simulation setups, and additional data that we refer to as "analytics". As the development of the course has stabilized, we have been able to devote more time to analyzing these data, extracting patterns of student behavior and how they have changed as the course has developed. During the most recent two semesters, pre- and post-tests of content knowledge related to the greenhouse effect were administered to assess changes in students' knowledge. The results of the Fall 2013 content assessment and an analysis of each step of every activity using the course platform analytics were used to identify problematic concepts and lesson elements, which were redesigned for the following semester. We observed a statistically significant improvement from pre to post instruction in Spring 2014. Preliminary results seem to indicate that several interactive activities, which replaced written/spoken content, contributed to this positive outcome. Our study demonstrates the benefit of deep analytics for thorough analysis of student results and quick iteration, allowing for significantly improved exercises to be redeployed quickly. The misconceptions that students have and retain depend on the individual student, although certain patterns do emerge in the class as a whole. These patterns can be seen in student discussion board behavior, the types of answers they submit, and the patterns of mistakes they make. By interrogating this wealth of data, we seek to identify the patterns that outstanding, struggling, and failing students display and how early in the class these patterns can be detected. If these patterns can be identified and detected early in the semester, instructors can intervene earlier, prodding unmotivated students while devoting significant attention to students who struggle yet remain interested in the subject matter. This offers a marked improvement over the more common practice of waiting (often futilely) for students to seek help.

Development of a low cost pupillometer-eyetracker and applications

NASA Astrophysics Data System (ADS)

Bianchetti, Arturo; Perez, Liliana I.; Comastri, Silvia A.

2013-11-01

The determination of ocular pupil diameter and gaze direction is important in various psychophysical and cognitive tests and can be accomplished using commercial, academic or open-source devices. In this work we develop a table-top pupillometer eyetracker termed Blick, the hardware costs 50 dollars and the software is open source (https://github.com/abianchetti/blick). The hardware is mounted in a portable holder and comprises an illumination system (two infrared LEDs generating 0.13 W/m2 at 22 cm) and a detection system (containing an USB camera, an infrared filter and a 16mm lens system) The software, programmed in C++ using OpenCV and cvblob libraries, processes eye images in real time and supplies plots and tables of pupil diameter and gaze direction and a video of the eye. As applications, capturing the right eye of six young emmetropes and after performing the pixel-mm and homographic calibrations (required to determine diameter in mm and gaze direction), we conduct three tests. The corresponding tasks are to detect mistakes in three series of four poker cards, to recognize letters F between distractors and to write a sentence via eye movements using Blick as eye tracker and the tool Dasher (MacKayśs Cambridge Group). We obtain that Blicḱs performance is satisfactory (errors being 0.05 mm in pupil diameter and 1 degree in gaze direction); that there are slight pupil dilations when subjects used to playing cards find mistakes and when some subjects find targets and, finally, that Blick can be employed as eyetracker to allow communication of disabled persons.

Medication errors in anesthesia: unacceptable or unavoidable?

PubMed

Dhawan, Ira; Tewari, Anurag; Sehgal, Sankalp; Sinha, Ashish Chandra

Medication errors are the common causes of patient morbidity and mortality. It adds financial burden to the institution as well. Though the impact varies from no harm to serious adverse effects including death, it needs attention on priority basis since medication errors' are preventable. In today's world where people are aware and medical claims are on the hike, it is of utmost priority that we curb this issue. Individual effort to decrease medication error alone might not be successful until a change in the existing protocols and system is incorporated. Often drug errors that occur cannot be reversed. The best way to 'treat' drug errors is to prevent them. Wrong medication (due to syringe swap), overdose (due to misunderstanding or preconception of the dose, pump misuse and dilution error), incorrect administration route, under dosing and omission are common causes of medication error that occur perioperatively. Drug omission and calculation mistakes occur commonly in ICU. Medication errors can occur perioperatively either during preparation, administration or record keeping. Numerous human and system errors can be blamed for occurrence of medication errors. The need of the hour is to stop the blame - game, accept mistakes and develop a safe and 'just' culture in order to prevent medication errors. The newly devised systems like VEINROM, a fluid delivery system is a novel approach in preventing drug errors due to most commonly used medications in anesthesia. Similar developments along with vigilant doctors, safe workplace culture and organizational support all together can help prevent these errors. Copyright © 2016. Published by Elsevier Editora Ltda.

Implementation and verification of global optimization benchmark problems

Posypkin, Mikhail; Usov, Alexander

2017-12-01

The paper considers the implementation and verification of a test suite containing 150 benchmarks for global deterministic box-constrained optimization. A C++ library for describing standard mathematical expressions was developed for this purpose. The library automate the process of generating the value of a function and its' gradient at a given point and the interval estimates of a function and its' gradient on a given box using a single description. Based on this functionality, we have developed a collection of tests for an automatic verification of the proposed benchmarks. The verification has shown that literary sources contain mistakes in the benchmarks description. The library and the test suite are available for download and can be used freely.

Phylogenetics links monster larva to deep-sea shrimp.

Mid-water plankton collections commonly include bizarre and mysterious developmental stages that differ conspicuously from their adult counterparts in morphology and habitat. Unaware of the existence of planktonic larval stages, early zoologists often misidentified these unique morphologies as independent adult lineages. Many such mistakes have since been corrected by collecting larvae, raising them in the lab, and identifying the adult forms. However, challenges arise when the larva is remarkably rare in nature and relatively inaccessible due to its changing habitats over the course of ontogeny. The mid-water marine species Cerataspis monstrosa (Gray 1828) is an armored crustacean larva whose adult identity has remained a mystery for over 180 years. Our phylogenetic analyses, based in part on recent collections from the Gulf of Mexico, provide definitive evidence that the rare, yet broadly distributed larva, C. monstrosa, is an early developmental stage of the globally distributed deepwater aristeid shrimp, Plesiopenaeus armatus. Divergence estimates and phylogenetic relationships across five genes confirm the larva and adult are the same species. Our work demonstrates the diagnostic power of molecular systematics in instances where larval rearing seldom succeeds and morphology and habitat are not indicative of identity. Larval-adult linkages not only aid in our understanding of biodiversity, they provide insights into the life history, distribution, and ecology of an organism.

[Migration of eight harmful elements from household products made with synthetic resin that infants may swallow by mistake].

Harmful elements are used as stabilizers and colorants in synthetic resin products. Accidental ingestion of harmful elements from such synthetic resins by infants is a dangerous health hazard. The Japanese Food Sanitation Law and the International Standard ISO 8124-3 "Safety of toys-Part 3: Migration of certain elements" control the levels of migrated harmful elements, such as lead or cadmium, from infants toys. However, the levels of migrated harmful elements from household products that are not infants toys are not controlled, since they are not covered by the law or standard. Therefore, we investigated the level of eight harmful elements (antimony, arsenic, barium, cadmium, chromium, lead, mercury and selenium) migrated from household products made of synthetic resin that infants may swallow by mistake. The extraction test of ISO 8124-3: 2010 was executed in 135 products (total 150 specimens), and the concentration of these elements was measured by inductively coupled plasma mass spectroscopy (ICP-MS). As a result, 1810 mg/kg and 1660 mg/kg of lead, exceeding the maximum acceptable level of the ISO standard, migrated from two products. In addition, lead and/or chromium at levels more than 1/10 of the maximum acceptable levels of the ISO standard migrated from four products. Household products that infants may swallow by mistake should ideally not release harmful elements such as lead and chromium.

Moral Distress, Workplace Health, and Intrinsic Harm.

PubMed

Weber, Elijah

2016-05-01

Moral distress is now being recognized as a frequent experience for many health care providers, and there's good evidence that it has a negative impact on the health care work environment. However, contemporary discussions of moral distress have several problems. First, they tend to rely on inadequate characterizations of moral distress. As a result, subsequent investigations regarding the frequency and consequences of moral distress often proceed without a clear understanding of the phenomenon being discussed, and thereby risk substantially misrepresenting the nature, frequency, and possible consequences of moral distress. These discussions also minimize the intrinsically harmful aspects of moral distress. This is a serious omission. Moral distress doesn't just have a negative impact on the health care work environment; it also directly harms the one who experiences it. In this paper, I claim that these problems can be addressed by first clarifying our understanding of moral distress, and then identifying what makes moral distress intrinsically harmful. I begin by identifying three common mistakes that characterizations of moral distress tend to make, and explaining why these mistakes are problematic. Next, I offer an account of moral distress that avoids these mistakes. Then, I defend the claim that moral distress is intrinsically harmful to the subject who experiences it. I conclude by explaining how acknowledging this aspect of moral distress should reshape our discussions about how best to deal with this phenomenon. © 2015 John Wiley & Sons Ltd.

Good people who try their best can have problems: recognition of human factors and how to minimise error.

Human error is as old as humanity itself and is an appreciable cause of mistakes by both organisations and people. Much of the work related to human factors in causing error has originated from aviation where mistakes can be catastrophic not only for those who contribute to the error, but for passengers as well. The role of human error in medical and surgical incidents, which are often multifactorial, is becoming better understood, and includes both organisational issues (by the employer) and potential human factors (at a personal level). Mistakes as a result of individual human factors and surgical teams should be better recognised and emphasised. Attitudes and acceptance of preoperative briefing has improved since the introduction of the World Health Organization (WHO) surgical checklist. However, this does not address limitations or other safety concerns that are related to performance, such as stress and fatigue, emotional state, hunger, awareness of what is going on situational awareness, and other factors that could potentially lead to error. Here we attempt to raise awareness of these human factors, and highlight how they can lead to error, and how they can be minimised in our day-to-day practice. Can hospitals move from being "high risk industries" to "high reliability organisations"? Copyright © 2015 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Complications: acknowledging, managing, and coping with human error.

Helo, Sevann; Moulton, Carol-Anne E

2017-08-01

Errors are inherent in medicine due to the imperfectness of human nature. Health care providers may have a difficult time accepting their fallibility, acknowledging mistakes, and disclosing errors. Fear of litigation, shame, blame, and concern about reputation are just some of the barriers preventing physicians from being more candid with their patients, despite the supporting body of evidence that patients cite poor communication and lack of transparency as primary drivers to file a lawsuit in the wake of a medical complication. Proper error disclosure includes a timely explanation of what happened, who was involved, why the error occurred, and how it will be prevented in the future. Medical mistakes afford the opportunity for individuals and institutions to be candid about their weaknesses while improving patient care processes. When a physician takes the Hippocratic Oath they take on a tremendous sense of responsibility for the care of their patients, and often bear the burden of their mistakes in isolation. Physicians may struggle with guilt, shame, and a crisis of confidence, which may thwart efforts to identify areas for improvement that can lead to meaningful change. Coping strategies for providers include discussing the event with others, seeking professional counseling, and implementing quality improvement projects. Physicians and health care organizations need to find adaptive ways to deal with complications that will benefit patients, providers, and their institutions.

Doctors charged with manslaughter in the course of medical practice, 1795-2005: a literature review

PubMed Central

Ferner, R E; McDowell, Sarah E

2006-01-01

Objectives: To quantify the number of doctors charged with manslaughter in the course of legitimate medical practice and to classify cases, as mistakes, slips (or lapses), and violations, using a recognized classification of human error system. Design: We searched newspaper databases, Medline, Embase, and the Wellcome library catalogue to identify relevant cases from 1795 to December 2005. Setting: Medical practice in the United Kingdom. Main outcome measure: Number of doctors charged with manslaughter in the course of medical practice. Results: We identified 85 doctors charged with manslaughter since 1795. The number of doctors charged was relatively high in the mid-19th century and the inter-war years, and has dramatically increased since 1990. Sixty of the doctors were acquitted, 22 were convicted, and three pleaded guilty. Most doctors were charged as a consequence of mistakes (37) or slips (17), and a minority because of alleged violations (16). Conclusions: The number of doctors prosecuted for manslaughter has risen steeply since 1990, but the proportion of doctors convicted remains low. Prosecution for deliberately violating rules is understandable, but accounts for only a minority of these cases. Unconscious errors—mistakes and slips (or lapses)—are an inescapable consequence of human actions and prosecution of individuals is unlikely to improve patient safety. That requires improvement to the complex systems of health care. PMID:16738374

A Case of Error Disclosure: A Communication Privacy Management Analysis

PubMed Central

Petronio, Sandra; Helft, Paul R.; Child, Jeffrey T.

2013-01-01

To better understand the process of disclosing medical errors to patients, this research offers a case analysis using Petronios’s theoretical frame of Communication Privacy Management (CPM). Given the resistance clinicians often feel about error disclosure, insights into the way choices are made by the clinicians in telling patients about the mistake has the potential to address reasons for resistance. Applying the evidenced-based CPM theory, developed over the last 35 years and dedicated to studying disclosure phenomenon, to disclosing medical mistakes potentially has the ability to reshape thinking about the error disclosure process. Using a composite case representing a surgical mistake, analysis based on CPM theory is offered to gain insights into conversational routines and disclosure management choices of revealing a medical error. The results of this analysis show that an underlying assumption of health information ownership by the patient and family can be at odds with the way the clinician tends to control disclosure about the error. In addition, the case analysis illustrates that there are embedded patterns of disclosure that emerge out of conversations the clinician has with the patient and the patient’s family members. These patterns unfold privacy management decisions on the part of the clinician that impact how the patient is told about the error and the way that patients interpret the meaning of the disclosure. These findings suggest the need for a better understanding of how patients manage their private health information in relationship to their expectations for the way they see the clinician caring for or controlling their health information about errors. Significance for public health Much of the mission central to public health sits squarely on the ability to communicate effectively. This case analysis offers an in-depth assessment of how error disclosure is complicated by misunderstandings, assuming ownership and control over information, unwittingly following conversational scripts that convey misleading messages, and the difficulty in regulating privacy boundaries in the stressful circumstances that occur with error disclosures. As a consequence, the potential contribution to public health is the ability to more clearly see the significance of the disclosure process that has implications for many public health issues.

2015-01-01

Interpersonal relationship disorders in adults with Attention Deficit Hyperactivity Disorder (ADHD) can be associated with the impairment of non-verbal communication. The purpose of our study was to compare the emotion recognition, facial recognition and neuropsychological assessments of adult ADHD patients with those of healthy controls, and to thus determine the effect of neuropsychological data on the recognition of emotional expressions. This study, which was based on a case-control model, was conducted with patients diagnosed with ADHD according to the DSM-IV-TR, being followed and monitored at the adult ADHD clinic of the Psychiatry Department of the Istanbul University Istanbul Medical Faculty Hospital. The study group consisted of 40 adults (27.5% female) between the ages of 20-65 (mean age 25.96 ± 6.07; education level: 15.02±2.34 years) diagnosed with ADHD, and 40 controls who were matched/similar with the study group with respect to age, gender, and education level. In the ADHD group, 14 (35%) of the patients had concomitant diseases. Pictures of Facial Affect, the Benton Face Recognition Test, and the Continuous Performance Test were used to respectively evaluate emotion recognition, facial recognition, and attention deficit and impulsivity of the patients. It was determined that, in comparison to the control group, the ADHD group made more mistakes in recognizing all types of emotional expressions and neutral expressions. The ADHD group also demonstrated more cognitive mistakes. Facial recognition was similar in both groups. It was determined that impulsivity had a significant effect on facial recognition. The social relationship disorders observed in ADHD can be affected by emotion recognition processes. In future studies, it may be possible to investigate the effects that early psychopharmacological and psychotherapeutic interventions administered for the main symptoms of ADHD have on the impairment of emotion recognition.

Objective Although most people will experience a traumatic event, only some will develop significant psychological symptoms in the aftermath. In the current study, we utilize a preexisting longitudinal study located in Long Island to examine the impact of Hurricane Sandy on internalizing symptoms in a large sample of children. We focused on temperamental fear and a biomarker of risk for anxiety, the error-related negativity (ERN). The ERN is a negative deflection in the event-related potential (ERP) occurring when individuals make mistakes and is increased in anxious individuals. Method The final sample consisted of 223 children who had undergone an observational assessment of fear at age 3 and an electroencephalogram assessment of the ERN at age 6. At the age 9 assessment, internalizing symptoms were assessed, and then again after the hurricane (approximately 65 weeks later). Results A significant three-way interaction between fearfulness, hurricane stressors, and the ERN in predicting post-hurricane increases in internalizing symptoms suggested that children who were high in fear at age 3 and experienced elevated hurricane stressors were characterized by subsequent increases in internalizing symptoms, but only when they were also characterized by an increased ERN at age 6. Conclusion These findings support a diathesis-stress model, suggesting that early temperament and pre-stressor biological markers confer risk for increased psychological symptoms following environmental stressors.

Exploring the chemical and biological space covered by patent applications is crucial in early-stage medicinal chemistry activities. Patent analysis can provide understanding of compound prior art, novelty checking, validation of biological assays, and identification of new starting points for chemical exploration. Extracting chemical and biological entities from patents through manual extraction by expert curators can take substantial amount of time and resources. Text mining methods can help to ease this process. To validate the performance of such methods, a manually annotated patent corpus is essential. In this study we have produced a large gold standard chemical patent corpus. We developed annotation guidelines and selected 200 full patents from the World Intellectual Property Organization, United States Patent and Trademark Office, and European Patent Office. The patents were pre-annotated automatically and made available to four independent annotator groups each consisting of two to ten annotators. The annotators marked chemicals in different subclasses, diseases, targets, and modes of action. Spelling mistakes and spurious line break due to optical character recognition errors were also annotated. A subset of 47 patents was annotated by at least three annotator groups, from which harmonized annotations and inter-annotator agreement scores were derived. One group annotated the full set. The patent corpus includes 400,125 annotations for the full set and 36,537 annotations for the harmonized set. All patents and annotated entities are publicly available at www.biosemantics.org.

[Psychosocial disintegration].

PubMed

Köhler, S

1994-08-01

Among the patients referred for rehabilitation in the latter half of their working life, many are notable due to considerable discrepancies between their objectively ascertainable performance and its subjectively perceived decline. In these cases, the "substantial threat to earning capacity" cannot be explained by measurable organ deficiencies. Similarly, treatment efforts focussed solely at improved somatic functioning remain inefficient in terms of stabilization of earning capacity, because they do not bring about changes in the cause of subjective performance deterioration. The author in these circumstances assumes the presence of an independent syndrome, called "psychosocial disintegration". He describes the full picture of this disease entity, and suggests causal mechanisms as well as potential for remedial intervention. On account of the considerable social dimension of the disorder outlined, early identification of these gradually developing changes as well as qualified care of the insurants are indispensable. All those involved in treatment and care of the patients or working in some branch of the social security system should be familiar with this psychosocial disintegration syndrome in order to avoid the guidance and counselling mistakes that are frequently the case. As rehabilitation is impossible in case of inhibiting personal attitudes of an insurant, it is advisable to verify the individual's readiness for rehabilitation and/or to strengthen it by appropriate measures before engaging in costly in-patient service provision. If the needed motivation is to be achieved during participation in a rehabilitation measure, extended service provision will invariably be required.

Crew resource management in the ICU: the need for culture change

PubMed Central

2012-01-01

Intensive care frequently results in unintentional harm to patients and statistics don’t seem to improve. The ICU environment is especially unforgiving for mistakes due to the multidisciplinary, time-critical nature of care and vulnerability of the patients. Human factors account for the majority of adverse events and a sound safety climate is therefore essential. This article reviews the existing literature on aviation-derived training called Crew Resource Management (CRM) and discusses its application in critical care medicine. CRM focuses on teamwork, threat and error management and blame free discussion of human mistakes. Though evidence is still scarce, the authors consider CRM to be a promising tool for culture change in the ICU setting, if supported by leadership and well-designed follow-up. PMID:22913855

An explosion of scientific publications over the last decades has increased the need for review articles: Carefully crafted scientific review articles can provide the novice reader with an overview of a new subject and provide the expert with a synthesis of scientific evidence, proof of reproducibility of published data and pooled estimates of common truth through meta-analyses. Unfortunately, while there are ample presentations and published guidelines for the preparation of scientific articles available, detailed information about how to properly prepare scientific review articles is relatively scarce. This perspective summarizes possible mistakes that can lead to misinformation in scientific review articles with the goal to help authors to improve the scientific contribution of their review article and thereby, increase the respective value of these articles for the scientific community.

Facets of perfectionism in a sample of hypersexual patients.

2012-11-01

This study investigated the role of perfectionism in a treatment-seeking sample (N = 136) of adult men and women using the Perfectionism Inventory (PI) and the Hypersexual Behavior Inventory (HBI). Several facets of perfectionism were positively correlated with hypersexuality, with the concern over mistakes scale from the PI accounting for most of the predictive variance in patterns of hypersexual behavior measured by the HBI. Items associated with concern over mistakes closely parallel the construct of shame noted in other studies of hypersexual patients. To a lesser degree, the PI scale planfulness also showed a negative relationship with hypersexuality, suggesting tendencies of impulsivity in the current patients. These data reinforce the findings in other studies that patterns of harsh self-criticism and impulsivity seem to strongly influence hypersexual behavior.

Arrogance analysis of several typical pattern recognition classifiers

Various kinds of classification methods have been developed. However, most of these classical methods, such as Back-Propagation (BP), Bayesian method, Support Vector Machine(SVM), Self-Organizing Map (SOM) are arrogant. A so-called arrogance, for a human, means that his decision, which even is a mistake, overstates his actual experience. Accordingly, we say that he is a arrogant if he frequently makes arrogant decisions. Likewise, some classical pattern classifiers represent the similar characteristic of arrogance. Given an input feature vector, we say a classifier is arrogant in its classification if its veracity is high yet its experience is low. Typically, for a new sample which is distinguishable from original training samples, traditional classifiers recognize it as one of the known targets. Clearly, arrogance in classification is an undesirable attribute. Conversely, a classifier is non-arrogant in its classification if there is a reasonable balance between its veracity and its experience. Inquisitiveness is, in many ways, the opposite of arrogance. In nature, inquisitiveness is an eagerness for knowledge characterized by the drive to question, to seek a deeper understanding. The human capacity to doubt present beliefs allows us to acquire new experiences and to learn from our mistakes. Within the discrete world of computers, inquisitive pattern recognition is the constructive investigation and exploitation of conflict in information. Thus, we quantify this balance and discuss new techniques that will detect arrogance in a classifier.

"Our Time is Up": A Relational Perspective on the Ending of a Single Psychotherapy Session.

PubMed

Gans, Jerome S

2016-12-31

This paper, written from a relational perspective, examines the final minutes of an individual psychotherapy session, and is organized around the topics of boundary negotiation, unwitting self-disclosures, visual challenges, and countertransference. Attending to session-ending material is important because the separation involved lends heightened emotional intensity to the oftensignificant material that appears in the final minutes. This material often serves as a bridge to the psychotherapeutic work to be taken up in subsequent sessions. Session-ending dynamics call upon the therapist to prioritize empathy, validation, and support for the patient suffering from early deprivation; identify and heal narcissistic injury in the patient wishing to be special; judiciously alter the frame when doing so will benefit the patient and not constitute a boundary violation; avoid re-traumatization; admit mistakes; confront blatant denial; advance agency; address uncomfortable topics; set appropriate limits; and deal authentically with uncomfortable countertransference. Numerous clinical examples serve to illustrate these clinical phenomena.

Board oversight of executive performance and compensation.

Making sure the relative roles of the board and management are clear and agreed upon is becoming more important as market and regulatory forces compel boards to govern at levels of detail once considered micromanagement, but are now required and necessary in the current environment of heightened governance accountability. A clear understanding of each other's roles and responsibilities is step one in building a solid partnership between the board and chief executive. A second element of building a strong foundation for the board-CEO relationship is taking time early on to establish mutual expectations about working together. The board's responsibilities in CEO performance management and compensation include setting performance expectations and goals that are clear and measurable and coaching and motivating the CEO. When a CEO fails, one of the most important steps for the board to take is to look in the mirror and commit to the rigorous due diligence needed to avoid future mistakes. Boards should always have CEO succession on their agenda.

Knowledge first, critique later: why it is a mistake for science education to encourage junior students to discuss, challenge and debate scientific knowledge.

PubMed

Charlton, Bruce G

2010-02-01

In UK educational circles it has long been regarded as a platitude that a good scientific education at school and undergraduate level should aim to teach critical thinking and encourage students to challenge mainstream science, debate scientific issues and express their personal opinions. However, I believe that this strategy is usually mistaken, and that such educational strategies probably do more harm than good. For most students, at most levels, for most of the time; science education should be focused on the inculcation of established knowledge. This is for the simple reason that critique is educationally-counterproductive and scientifically-worthless unless or until underpinned by adequate knowledge and competence. Instead, for the early years of science teaching, the basic assumption ought to be that the student is there to learn science; not to confront science. The basic attitude being taught should be one of humility before the science being studied.

How Fred Hoyle Reconciled Radio Source Counts and the Steady State Cosmology

NASA Astrophysics Data System (ADS)

Ekers, Ron

2012-09-01

In 1969 Fred Hoyle invited me to his Institute of Theoretical Astronomy (IOTA) in Cambridge to work with him on the interpretation of the radio source counts. This was a period of extreme tension with Ryle just across the road using the steep slope of the radio source counts to argue that the radio source population was evolving and Hoyle maintaining that the counts were consistent with the steady state cosmology. Both of these great men had made some correct deductions but they had also both made mistakes. The universe was evolving, but the source counts alone could tell us very little about cosmology. I will try to give some indication of the atmosphere and the issues at the time and look at what we can learn from this saga. I will conclude by briefly summarising the exponential growth of the size of the radio source counts since the early days and ask whether our understanding has grown at the same rate.

The fundamental ISS payload integration philosophy, processes and capabilities were established in the context of how NASA science programs were conducted and executed in the early 1990 s. Today, with the designation of the United States (US) portion of ISS as a National Lab, the ISS payload customer base is growing to include other government agencies, private and commercial research. The fields of research are becoming more diverse expanding from the NASA centric physical, materials and human research sciences to test beds for exploration and technology demonstration, biology and biotechnology, and as an Earth and Space science platform. This new customer base has a broader more diverse set of expectations and requirements for payload design, verification, integration, test, training, and operations. One size fits all processes are not responsive to this broader customer base. To maintain an organization s effectiveness it must listen to its customers, understand their needs, learn from its mistakes, and foster an environment of continual process improvement. The ISS Payloads office is evolving to meet these new customer expectations.

[Historical archives of Italian nephrology: The history of instrumentation in nephrology. Part I: Theoretical bases].

Timio, M

2002-01-01

Microscopes and artificial kidneys have greatly influenced both diagnosis and therapy of renal diseases. Nonetheless, in tracing the influence of instrumentation on nephrology, as revealed by daily activity, we have to recognise the influence of science upon medical instruments. It is for this reason that, besides strictly clinical factors, the scientific factors that contributed to the development of modern nephrology have received considerable attention. Nobody can use an artificial kidney without bearing in mind the contribution of many segments of science. Each segment has a hypothesis in its historical growth, development and decline. The notion that the advancement of science was made possible by the increasing reliance measurements and other quantitative procedure is hardly a novel one. Moreover, it is rather obvious that the experimental process and the use of instrumentation played an important role in the history of nephrology. Measurements, experiments and the use of instruments were interrelated and represented many phases of the improvements made in diagnosis and therapeutics. Naturally, in the history and epistemology of nephrology instrumentation we find conceptual mistakes and erroneous approaches to the biological reality. However, according to Popper's teachings, mistakes are good for science as they give an extra kick to its growth and development. Medical instrumentation is an assembly of scientific theories; it also controls medical theories and promotes the development of new ones. In addition, it changed our approach to the patient. In the pre-physical era, medical practice was almost entirely an intellectual process based on medical theories that the patient was not expected to understand. In the period of physical examinations the physician included the sensual dimension (oral and visual process) and made direct contact with the patient. In the instrumentation period we experience the third type of examination, in which the physician went back to the position of having less contact with the patient. This separation is reminiscent of the pre-physical diagnosis.

The "Arab Spring" has touched almost all countries in the Middle East and North Africa. While most attention has focused on security and political developments, there are significant consequences for population health. These include immediate problems, such as violent deaths and injuries, population displacement, and damage to essential infrastructure, but also longer term vulnerabilities not yet addressed by the political changes, including high unemployment, the low status of women, erosion of already weak welfare systems, and rising food prices. It will be important to tackle these underlying issues while not repeating the mistakes made in other countries that have undergone rapid political transition.

Tissue engineering has always had an applied focus and there is hardly an academic publication that does not mention the applicability of its findings to the future development of a medical product. I have been involved in the industry side of tissue engineering from the start, pursuing a variety of applications, some making it to the marketplace. There have been many lessons that I have learned from direct experience (mistakes and successes), observation, through advising others, and now, in developing innovative ways to identify and eliminate the regenerative cell populations within a tumor. This brief overview of some of these lessons is written with the next generation of pioneering product developers in mind: the biologists, biochemists, and engineers who will dedicate their careers to driving medical and commercial progress in tissue engineering.

The main difference between a virtual reality and a generic representation is to be directly involved into the action you are performing. As a matter of fact, within the shift from real to virtual world, our biological physique does not mutate but is amplified and connected to the virtual world by technological interfaces. Training using a virtual reality simulator is an option to supplement (or replace) standard training. One of the two main goals of our study is to test, at first, how much students enrolled to the Faculty of Medicine at "University Campus Bio-Medico of Rome" are familiar with synthetic worlds, how long they have been using them and how they would like their Avatar to look like. Moreover, the second aim is to collect students' opinion about the use of virtual, interactive environments to enable learning and participation in dynamic, problem based, clinical, virtual simulations. Simulations might be used to allow learners to make mistakes safely in lieu of real life situations, learn from those mistakes and ultimately to improve performances by subsequent avoidance of those mistakes. The selected approach to the study is based on a semi-structured questionnaire made of 14 questions administered to all the medical students. Most of the students appear not to be very confident with virtual worlds mostly because of a lack of interest. However, a large majority of them are likely to use a virtual world for fun or escaping from reality. Students would select and customize their Avatar by giving her/him the same sexual identity, same figure, same social class but different employment. It is important to notice that a wide majority of the students is interested in practicing on a virtual world in order to manage new experiences and being able to face them; their willing is to get benefits from the ability to make mistakes in a safe environment as well as to record a positive impact on their understanding.

Plant identification credibility in ethnobotany: a closer look at Polish ethnographic studies

PubMed Central

2010-01-01

Background This paper is an attempt to estimate the percentage of erroneously identified taxa in ethnographic studies concerning the use of plants and to propose a code for recording credibility of identification in historical ethnobotany publications. Methods A sample of Polish-language ethnobotanical literature (45 published sources from 1874-2005) and four collections of voucher specimens (from 1894-1975) were analyzed. Errors were detected in the publications by comparing the data with existing knowledge on the distribution of plant names and species ranges. The voucher specimens were re-examined. A one-letter code was invented for quick identification of the credibility of data published in lists of species compiled from historical or ethnographic sources, according to the source of identification: voucher specimen, Latin binominal, botanical expert, obvious widespread name, folk name, mode of use, range, physical description or photograph. To test the use of the code an up-to-date list of wild food plants used in Poland was made. Results A significant difference between the ratio of mistakes in the voucher specimen collections and the ratio of detectable mistakes in the studies without herbarium documentation was found. At least 2.3% of taxa in the publications were identified erroneously (mean rate was 6.2% per publication), and in half of these mistakes even the genus was not correct. As many as 10.0% of voucher specimens (on average 9.2% per collection) were originally erroneously identified, but three quarters of the identification mistakes remained within-genus. The species of the genera Thymus, Rumex and Rubus were most often confused within the genus. Not all of the invented credibility codes were used in the list of wild food plants, but they may be useful for other researchers. The most often used codes were the ones signifying identification by: voucher specimen, botanical expert and by a common name used throughout the country. Conclusions The results of this study support the rigorous use of voucher specimens in ethnobotany, although they also reveal a relatively high percentage of misidentified taxa in the specimens studied. The invented credibility coding system may become a useful tool for communication between historical ethnobotanists, particularly in creating larger databases. PMID:21167056

Biobased food packaging materials are gaining more attention owing to their intrinsic biodegradable nature and renewability. Selection of suitable biobased polymers for food packaging applications could be a tedious task with potential mistakes in choosing the best materials. In this paper, an expert system was developed using Exsys Corvid software to select suitable biobased polymer materials for packaging fruits, dry food and dairy products. If - Then rule based system was utilized to accomplish the material selection process whereas a score system was formulated to facilitate the ranking of selected materials. The expert system selected materials that satisfied all constraints and selection results were presented in suitability sequence depending on their scores. The expert system selected polylactic acid (PLA) as the most suitable material.

Sensory illusions: Common mistakes in physics regarding sound, light and radio waves

2013-03-01

Optical illusions are well known as effects that we see that are not representative of reality. Sensory illusions are similar but can involve other senses than sight, such as hearing or touch. One mistake commonly noted among instructors is that students often mis-identify radio signals as sound waves and not as part of the electromagnetic spectrum. A survey of physics students from multiple high schools highlights the frequency of this common misconception, as well as other nuances on this misunderstanding. Many students appear to conclude that, since they experience radio broadcasts as sound, then sound waves are the actual transmission of radio signals and not, as is actually true, a representation of those waves as produced by the translator box, the radio. Steps to help students identify and correct sensory illusion misconceptions are discussed. School of Education

In contrast to the law governing complaints and to disciplinary law, a civil law judge can sentence dentists to the restoration of all damages to patients. For this to happen, there has to be evidence of damage, responsibility and a causal connection. For the assumption of responsibility as well as a causal connection, an important question is whether a dentist has violated a relevant guideline or protocol. Moreover, dentists are not only responsible for their own mistakes, but also, in principle, for those of their employees. Depending on the situation, dentists can also be held accountable for the mistakes of a dentist who is working in their practice on a self-employed basis. Dutch dentists do not yet have to fear American situations', because damages awarded in The Netherlands are still relatively low.

1998-04-01

The precipitating factors of repetitive exacerbation were investigated in 110 consecutive patients with chronic left heart failure admitted due to acute exacerbation more than twice to the medical emergency ward of National Cardiovascular Center from January, 1992 to December, 1996. The controls were 189 consecutive patients with chronic left heart failure admitted to the ward due to acute exacerbation only once during the same period. Excessive intake of water or sodium, overwork and infection were common precipitating factors in the first decompensation of left heart failure, but the former two factors became less common with repeated admission. Patient mistakes such as excessive intake of water or sodium, overwork and noncompliance with medications, and new onset arrhythmias were common precipitating factors in patients (n = 13) admitted to the ward more than four times. Infection was a common precipitating factor (63%) in patients with a time interval between readmission and the last discharge of longer than 2 years. Despite repeated admission, infection was a common precipitating factor in patients with valvular heart disease (n = 31), patient mistakes were common in heart disease with left ventricular hypertrophy (n = 20), and infection and new onset arrhythmias were common in dilated cardiomyopathy (n = 28) and old myocardial infarction (n = 31). Patient mistakes and new onset arrhythmias were the common factors that led to repetitive exacerbation of left heart failure, and precipitating factors were characterized by the etiology of left heart failure.

Scientific Progress or Regress in Sports Physiology?

PubMed

Böning, Dieter

2016-11-01

In modern societies there is strong belief in scientific progress, but, unfortunately, a parallel partial regress occurs because of often avoidable mistakes. Mistakes are mainly forgetting, erroneous theories, errors in experiments and manuscripts, prejudice, selected publication of "positive" results, and fraud. An example of forgetting is that methods introduced decades ago are used without knowing the underlying theories: Basic articles are no longer read or cited. This omission may cause incorrect interpretation of results. For instance, false use of actual base excess instead of standard base excess for calculation of the number of hydrogen ions leaving the muscles raised the idea that an unknown fixed acid is produced in addition to lactic acid during exercise. An erroneous theory led to the conclusion that lactate is not the anion of a strong acid but a buffer. Mistakes occur after incorrect application of a method, after exclusion of unwelcome values, during evaluation of measurements by false calculations, or during preparation of manuscripts. Co-authors, as well as reviewers, do not always carefully read papers before publication. Peer reviewers might be biased against a hypothesis or an author. A general problem is selected publication of positive results. An example of fraud in sports medicine is the presence of doped subjects in groups of investigated athletes. To reduce regress, it is important that investigators search both original and recent articles on a topic and conscientiously examine the data. All co-authors and reviewers should read the text thoroughly and inspect all tables and figures in a manuscript.

[A possible objective from now to the year 2000: reducing infant mortality by one half in Third World countries].

Berthet, E

1984-06-01

Every day 40.000 children die throughout the world. Most of them in developing countries. There is a close relationship between infant mortality, life expectancy at birth, the adult illiteracy rate and national income per capita. Why such huge differences between the infant mortality rate of 7 per 1.000 (live births) in Sweden and 208 in Upper Volta? The four scourges which afflict developing countries: hunger (malnutrition), disease, ignorance and poverty are responsible for this state of affairs. The author suggests that coordinated action by governments and International Agencies should be taken to halve the infant mortality rate by the year 2.000. He notes that in the past three mistakes were made which should not be repeated. The first was to improve the living conditions of the population. The green Revolution in India provides a striking example of an important progress which benefited only the wealthier farmers. A second mistake was to believe that only a medical approach reduce the infant mortality rate. A third error was to overlook the importance of health education and not to seek the active participation of the people concerned. The author recalls that the International Union for Health Education carried out a sanitary and social programme from 1975 to 1978 in Africa, south of the Sahara. To this effect, the IUHE had to find out what the people really wanted, could be motivated, to increase the welfare of the villagers by measures adapted to existing possibilities, to study how the people could recruit among the villagers health workers and train them, to create village health committees.(ABSTRACT TRUNCATED AT 250 WORDS)

Learning from Inconsistency

NASA Technical Reports Server (NTRS)

Easterbrook, Steve

1996-01-01

This position paper argues that inconsistencies that occur during the development of a software specification offer an excellent way of learning more about the development process. We base this argument on our work on inconsistency management. Much attention has been devoted recently to the need to allow inconsistencies to occur during software development, to facilitate flexible development strategies, especially for collaborative work. Recent work has concentrated on reasoning in the presence of inconsistency, tracing inconsistencies with 'pollution markers' and supporting resolution. We argue here that one of the most important aspects of inconsistency is the learning opportunity it provides. We are therefore concerned with how to capture this learning outcome so that its significance is not lost. We present a small example of how apprentice software engineers learn from their mistakes, and outline how an inconsistency management tool could support this learning. We then argue that the approach can be used more generally as part of continuous process improvement.

To assess the prevalence and patterns of learning disabilities (LD) in school going children in a northern city of India. The present cross-sectional study comprised of three-staged screening procedure for assessing learning disabilities of 3rd and 4th grade students studying in government schools. The first stage comprised of the teacher identifying at-risk student. In the second stage, teachers assessed at-risk students using Specific Learning Disability-Screening Questionnaire (SLD-SQ). The third stage comprised of assessment of the screen positive students using Brigance Diagnostic Inventory (BDI) part of NIMHANS Index of Specific Learning Disabilities for identifying the cases of LD. A total of 1211 (33.6%) children out of the total screened (n = 3600) were identified as at-risk by the teachers at the first stage. Of them, 360 were found to screen positive on the second stage using SLD-SQ. The most common deficits were missing out words or sentences while reading, misplacing letters or words while reading or writing, and making frequent mistake in spelling while writing or reading. Of these, 108 children were confirmed to have learning disability on the third stage using BDI, which represented 3.08% of the total population. Learning disability is an important concern in young school aged children. Early identification of such students can help in early institution of intervention and suitable modifications in teaching techniques.

Human activities such as hydropower development, water withdrawals, and commercial fisheries often put fish species at risk. Engineered solutions designed to protect species or their life stages are frequently based on assumptions about swimming performance and behaviors. In many cases, however, the appropriate data to support these designs are either unavailable or misapplied. This article provides an overview of the state of knowledge of fish swimming performance – where the data come from and how they are applied – identifying both gaps in knowledge and common errors in application, with guidance on how to avoid repeating mistakes, as well as suggestions for further study.

A basic paradigm that allows representation of physical systems with a focus on context and time is presented. Paragon provides the capability to quickly capture an expert's knowledge in a cognitively resonant manner. From that description, Paragon creates a simulation model in LISP, which when executed, verifies that the domain expert did not make any mistakes. The Achille's heel of rule-based systems has been the lack of a systematic methodology for testing, and Paragon's developers are certain that the model-based approach overcomes that problem. The reason this testing is now possible is that software, which is very difficult to test, has in essence been transformed into hardware.

The main attention was given to such parameters of the injurious exposure as loading conditions (mass, speed, direction) and the surface properties of the traumatic agent (area, shape, hardness). It is expected that the use of the proposed system for the evaluation of the injurious exposure in the practical work of forensic medical experts will enhance the reliability of their conclusions and help to avoid mistakes.

Human-Computer Interaction, Tourism and Cultural Heritage

NASA Astrophysics Data System (ADS)

Cipolla Ficarra, Francisco V.

We present a state of the art of the human-computer interaction aimed at tourism and cultural heritage in some cities of the European Mediterranean. In the work an analysis is made of the main problems deriving from training understood as business and which can derail the continuous growth of the HCI, the new technologies and tourism industry. Through a semiotic and epistemological study the current mistakes in the context of the interrelations of the formal and factual sciences will be detected and also the human factors that have an influence on the professionals devoted to the development of interactive systems in order to safeguard and boost cultural heritage.

Identity change and informed consent

PubMed Central

Witt, Karsten

2017-01-01

In this paper, I focus on a kind of medical intervention that is at the same time fascinating and disturbing: identity-changing interventions. My guiding question is how such interventions can be ethically justified within the bounds of contemporary bioethical mainstream that places great weight on the patient's informed consent. The answer that is standardly given today is that patients should be informed about the identity effects, thus suggesting that changes in identity can be treated like ‘normal’ side effects. In the paper, I argue that this approach is seriously lacking because it misses important complexities going along with decisions involving identity changes and consequently runs into mistakes. As a remedy I propose a new approach, the ‘perspective-sensitive account’, which avoids these mistakes and thus provides the conceptual resources to systematically reflect on and give a valid consent to identity-changing interventions.

The power of apology: how saying sorry can leave both patients and nurses feeling better.

PubMed

Armstrong, Dorothy

Saying sorry to a patient can be a difficult part of nursing practice. But a sincere and prompt apology, using appropriate language and tone, can help those involved come to terms with something that has gone wrong. Nurses may be concerned that saying sorry will make litigation morelikely, but the evidence is that patients are less likely to resort to the courts if they feel they have been listened to and have been offered a "proper" apology. A complete apology expresses regret and acknowledges fault or shortcoming. One technique that nurses can use when having to make a difficult apology is to use the three Rs: regret (saying sorry and accepting responsibility); reason (providing a reason for the mistake); and remedy (trying to resolve the mistake as far as possible). Apologies can be of benefit not only to patients and relatives, but also to nurses.

Boosting with Averaged Weight Vectors

NASA Technical Reports Server (NTRS)

Oza, Nikunj C.; Clancy, Daniel (Technical Monitor)

2002-01-01

AdaBoost is a well-known ensemble learning algorithm that constructs its constituent or base models in sequence. A key step in AdaBoost is constructing a distribution over the training examples to create each base model. This distribution, represented as a vector, is constructed to be orthogonal to the vector of mistakes made by the previous base model in the sequence. The idea is to make the next base model's errors uncorrelated with those of the previous model. Some researchers have pointed out the intuition that it is probably better to construct a distribution that is orthogonal to the mistake vectors of all the previous base models, but that this is not always possible. We present an algorithm that attempts to come as close as possible to this goal in an efficient manner. We present experimental results demonstrating significant improvement over AdaBoost and the Totally Corrective boosting algorithm, which also attempts to satisfy this goal.

Clarification of terminology in medication errors: definitions and classification.

PubMed

Ferner, Robin E; Aronson, Jeffrey K

2006-01-01

We have previously described and analysed some terms that are used in drug safety and have proposed definitions. Here we discuss and define terms that are used in the field of medication errors, particularly terms that are sometimes misunderstood or misused. We also discuss the classification of medication errors. A medication error is a failure in the treatment process that leads to, or has the potential to lead to, harm to the patient. Errors can be classified according to whether they are mistakes, slips, or lapses. Mistakes are errors in the planning of an action. They can be knowledge based or rule based. Slips and lapses are errors in carrying out an action - a slip through an erroneous performance and a lapse through an erroneous memory. Classification of medication errors is important because the probabilities of errors of different classes are different, as are the potential remedies.

[What is the "Ductus Botallo"? It is an error].

PubMed

Péterffy, Arpád; Péterffy, Mikael

2008-01-01

The aim of this publication is to call the attention of the Hungarian medical society to the incorrect name "ductus Botalli" of ductus arteriosus connecting pulmonary artery and aorta. This patent vascular connection has an important role in the fetal circulation, but after birth it becomes unnecessary and blocked. In the 16th century Leonardo Botallo the Italian physician and military surgeon described and named after himself an anatomical structure foramen ovale. The unfortunate mistake happened in a later edition of his work. The translation of this edition into German may have contributed to the error, as the name "ductus Botalli" was spread in the countries under German influence (Scandinavia, Hungary), but not in the English and Spanish medical language. Considering that the naming "ductus Botalli" is used by mistake it is most desirable to ignore it in the Hungarian medical language, as well--as it has already happened in German and Scandinavian medical publications.

Validating crash locations for quantitative spatial analysis: a GIS-based approach.

PubMed

Loo, Becky P Y

2006-09-01

In this paper, the spatial variables of the crash database in Hong Kong from 1993 to 2004 are validated. The proposed spatial data validation system makes use of three databases (the crash, road network and district board databases) and relies on GIS to carry out most of the validation steps so that the human resource required for manually checking the accuracy of the spatial data can be enormously reduced. With the GIS-based spatial data validation system, it was found that about 65-80% of the police crash records from 1993 to 2004 had correct road names and district board information. In 2004, the police crash database contained about 12.7% mistakes for road names and 9.7% mistakes for district boards. The situation was broadly comparable to the United Kingdom. However, the results also suggest that safety researchers should carefully validate spatial data in the crash database before scientific analysis.

Evolution of direct reciprocity under uncertainty can explain human generosity in one-shot encounters

PubMed Central

Delton, Andrew W.; Krasnow, Max M.; Cosmides, Leda; Tooby, John

2011-01-01

Are humans too generous? The discovery that subjects choose to incur costs to allocate benefits to others in anonymous, one-shot economic games has posed an unsolved challenge to models of economic and evolutionary rationality. Using agent-based simulations, we show that such generosity is the necessary byproduct of selection on decision systems for regulating dyadic reciprocity under conditions of uncertainty. In deciding whether to engage in dyadic reciprocity, these systems must balance (i) the costs of mistaking a one-shot interaction for a repeated interaction (hence, risking a single chance of being exploited) with (ii) the far greater costs of mistaking a repeated interaction for a one-shot interaction (thereby precluding benefits from multiple future cooperative interactions). This asymmetry builds organisms naturally selected to cooperate even when exposed to cues that they are in one-shot interactions. PMID:21788489

Letting yourself be nominated for a conference summary talk is considered by some to be a big mistake. It eliminates the possibility of making up the sleep lost at night, while partying, during the day, while sitting in the talks. It even forces you to look at all the poster papers. But at a meeting like this, with the wealth of observational data, it is definitely not a mistake: it was even worth missing some of the parties! My problem was to devise a way to be sufficiently selective so as to provide a reasonably coherent summary. I chose to emphasize the multitude of large-scale maps presented at the meeting. Many are relevant to the ``worm paradigm'' (Sec. 2), and the recent γ-ray and ROSAT results are relevant to the Hot Ionized Medium (Sec. 3). And finally, I was impressed by a number of well-crafted smaller-scale observations, which elucidate particular aspects of the interstellar medium (Sec. 4).

Thirty years of great ape gestures.

PubMed

Tomasello, Michael; Call, Josep

2018-02-21

We and our colleagues have been doing studies of great ape gestural communication for more than 30 years. Here we attempt to spell out what we have learned. Some aspects of the process have been reliably established by multiple researchers, for example, its intentional structure and its sensitivity to the attentional state of the recipient. Other aspects are more controversial. We argue here that it is a mistake to assimilate great ape gestures to the species-typical displays of other mammals by claiming that they are fixed action patterns, as there are many differences, including the use of attention-getters. It is also a mistake, we argue, to assimilate great ape gestures to human gestures by claiming that they are used referentially and declaratively in a human-like manner, as apes' "pointing" gesture has many limitations and they do not gesture iconically. Great ape gestures constitute a unique form of primate communication with their own unique qualities.

Benefits of Operational Consideration into the Guidance, Navigation, and Control Design of Spacecraft

NASA Technical Reports Server (NTRS)

Morris, Mark C.; Holt, Greg N.

2011-01-01

The following paper points out historical examples where operational consideration into the GN&C design could have helped avoid operational complexity, reduce costs, ensure the ability for a GN&C system to be able to adapt to failures, and in some cases might have helped save mission objectives. A costly repeat of mistakes could befall a program if previous operational lessons, especially from operators of vehicles with similar GN&C systems, are not considered during the GN&C design phase of spacecraft. The information gained from operational consideration during the design can lead to improvements of the design, allow less ground support during operations, and prevent repetition of previous mistakes. However, this benefit can only occur if spacecraft operators adequately capture lessons learned that would improve future designs for operations and those who are designing spacecraft incorporate inputs from those that have previously operated similar GN&C systems.

[Critical incidents].

PubMed

Scheidegger, D

2005-03-01

In medicine real severe mishaps are rare. On the other hand critical incidents are frequent. Anonymous critical incident reporting systems allow us to learn from these mishaps. This learning process will make our daily clinical work safer Unfortunately, before these systems can be used efficiently our professional culture has to be changed. Everyone in medicine has to admit that errors do occur to see the need for an open discussion. If we really want to learn from errors, we cannot punish the individual, who reported his or her mistake. The interest is primarily in what has happened and why it has happened and not who has committed this mistake. The cause for critical incidents in medicine is in over 80% the human factor Poor communication, work under enormous stress, conflicts and hierarchies are the main cause. This has been known for many years, therefore have already 15 years ago high-tech industries, like e.g. aviation, started to invest in special courses on team training. Medicine is a typical profession were until now only the individual performance decided about the professional career Communication, conflict management, stress management, decision making, risk management, team and team resource management were subjects that have never been taught during our preor postgraduate education. These points are the most important ones for an optimal teamwork. A multimodular course designed together with Swissair (Human Aspect Development medical, HADmedical) helps to cover, as in aviation, the soft factor and behavioural education in medicine and to prepare professionals in health care to work as a real team.

AveBoost2: Boosting for Noisy Data

NASA Technical Reports Server (NTRS)

Oza, Nikunj C.

2004-01-01

AdaBoost is a well-known ensemble learning algorithm that constructs its constituent or base models in sequence. A key step in AdaBoost is constructing a distribution over the training examples to create each base model. This distribution, represented as a vector, is constructed to be orthogonal to the vector of mistakes made by the pre- vious base model in the sequence. The idea is to make the next base model's errors uncorrelated with those of the previous model. In previous work, we developed an algorithm, AveBoost, that constructed distributions orthogonal to the mistake vectors of all the previous models, and then averaged them to create the next base model s distribution. Our experiments demonstrated the superior accuracy of our approach. In this paper, we slightly revise our algorithm to allow us to obtain non-trivial theoretical results: bounds on the training error and generalization error (difference between training and test error). Our averaging process has a regularizing effect which, as expected, leads us to a worse training error bound for our algorithm than for AdaBoost but a superior generalization error bound. For this paper, we experimented with the data that we used in both as originally supplied and with added label noise-a small fraction of the data has its original label changed. Noisy data are notoriously difficult for AdaBoost to learn. Our algorithm's performance improvement over AdaBoost is even greater on the noisy data than the original data.

Coming up short on nonfinancial performance measurement.

PubMed

Ittner, Christopher D; Larcker, David F

2003-11-01

Companies in increasing numbers are measuring customer loyalty, employee satisfaction, and other nonfinancial areas of performance that they believe affect profitability. But they've failed to relate these measures to their strategic goals or establish a connection between activities undertaken and financial outcomes achieved. Failure to make such connections has led many companies to misdirect their investments and reward ineffective managers. Extensive field research now shows that businesses make some common mistakes when choosing, analyzing, and acting on their nonfinancial measures. Among these mistakes: They set the wrong performance targets because they focus too much on short-term financial results, and they use metrics that lack strong statistical validity and reliability. As a result, the companies can't demonstrate that improvements in nonfinancial measures actually affect their financial results. The authors lay out a series of steps that will allow companies to realize the genuine promise of nonfinancial performance measures. First, develop a model that proposes a causal relationship between the chosen nonfinancial drivers of strategic success and specific outcomes. Next, take careful inventory of all the data within your company. Then use established statistical methods for validating the assumed relationships and continue to test the model as market conditions evolve. Finally, base action plans on analysis of your findings, and determine whether those plans and their investments actually produce the desired results. Nonfinancial measures will offer little guidance unless you use a process for choosing and analyzing them that relies on sophisticated quantitative and qualitative inquiries into the factors actually contributing to economic results.

Sensitive detection of C-reactive protein in serum by immunoprecipitation-microchip capillary gel electrophoresis.

Sepsis represents a significant cause of mortality in intensive care units. Early diagnosis of sepsis is essential to increase the survival rate of patients. Among others, C-reactive protein (CRP) is commonly used as a sepsis marker. In this work we introduce immune precipitation combined with microchip capillary gel electrophoresis (IP-MCGE) for the detection and quantification of CRP in serum samples. First high-abundance proteins (HSA, IgG) are removed from serum samples using affinity spin cartridges, and then the remaining proteins are labeled with a fluorescence dye and incubated with an anti-CRP antibody, and the antigen/antibody complex is precipitated with protein G-coated magnetic beads. After precipitation the complex is eluted from the beads and loaded onto the MCGE system. CRP could be reliably detected and quantified, with a detection limit of 25 ng/μl in serum samples and 126 pg/μl in matrix-free samples. The overall sensitivity (LOQ = 75 ng/μl, R(2) = 0.9668) of the method is lower than that of some specially developed methods (e.g., immune radiometric assay) but is comparable to those of clinically accepted ELISA methods. The straightforward sample preparation (not prone to mistakes), reduced sample and reagent volumes (including the antibodies), and high throughput (10 samples/3 h) are advantages and therefore IP-MCGE bears potential for point-of-care diagnosis.

Learning from Mistakes

2006-01-01

CONTEXT Trainees are exposed to medical errors throughout medical school and residency. Little is known about what facilitates and limits learning from these experiences. OBJECTIVE To identify major factors and areas of tension in trainees' learning from medical errors. DESIGN, SETTING, AND PARTICIPANTS Structured telephone interviews with 59 trainees (medical students and residents) from 1 academic medical center. Five authors reviewed transcripts of audiotaped interviews using content analysis. RESULTS Trainees were aware that medical errors occur from early in medical school. Many had an intense emotional response to the idea of committing errors in patient care. Students and residents noted variation and conflict in institutional recommendations and individual actions. Many expressed role confusion regarding whether and how to initiate discussion after errors occurred. Some noted the conflict between reporting errors to seniors who were responsible for their evaluation. Learners requested more open discussion of actual errors and faculty disclosure. No students or residents felt that they learned better from near misses than from actual errors, and many believed that they learned the most when harm was caused. CONCLUSIONS Trainees are aware of medical errors, but remaining tensions may limit learning. Institutions can immediately address variability in faculty response and local culture by disseminating clear, accessible algorithms to guide behavior when errors occur. Educators should develop longitudinal curricula that integrate actual cases and faculty disclosure. Future multi-institutional work should focus on identified themes such as teaching and learning in emotionally charged situations, learning from errors and near misses and balance between individual and systems responsibility.

How Has Educational Expansion Shaped Social Mobility Trends in the United States?

PubMed Central

Pfeffer, Fabian T.; Hertel, Florian R.

2015-01-01

This contribution provides a long-term assessment of intergenerational social mobility trends in the United States across the 20th and early 21st century and assesses the determinants of those trends. In particular, we study how educational expansion has contributed to the observed changes in mobility opportunities for men across cohorts. Drawing on recently developed decomposition methods, we empirically identify the contribution of each of the multiple channels through which changing rates of educational participation shape mobility trends. We find that a modest but gradual increase in social class mobility can nearly exclusively be ascribed to an interaction known as the compositional effect, according to which the direct influence of social class backgrounds on social class destinations is lower among the growing number of individuals attaining higher levels of education. This dominant role of the compositional effect is also due to the fact that, despite pronounced changes in the distribution of education, class inequality in education has remained stable while class returns to education have shown no consistent trend. Our analyses also provide a cautionary tale about mistaking increasing levels of social class mobility for a general trend towards more fluidity in the United States. The impact of parental education on son's educational and class attainment has grown or remained stable, respectively. Here, the compositional effect pertaining to the direct association between parental education and son's class attainment counteracts a long-term trend of increasing inequality in educational attainment tied to parents' education.

A String of Mistakes: The Importance of Cascade Analysis in Describing, Counting, and Preventing Medical Errors

PubMed Central

Woolf, Steven H.; Kuzel, Anton J.; Dovey, Susan M.; Phillips, Robert L.

2004-01-01

BACKGROUND Notions about the most common errors in medicine currently rest on conjecture and weak epidemiologic evidence. We sought to determine whether cascade analysis is of value in clarifying the epidemiology and causes of errors and whether physician reports are sensitive to the impact of errors on patients. METHODS Eighteen US family physicians participating in a 6-country international study filed 75 anonymous error reports. The narratives were examined to identify the chain of events and the predominant proximal errors. We tabulated the consequences to patients, both reported by physicians and inferred by investigators. RESULTS A chain of errors was documented in 77% of incidents. Although 83% of the errors that ultimately occurred were mistakes in treatment or diagnosis, 2 of 3 were set in motion by errors in communication. Fully 80% of the errors that initiated cascades involved informational or personal miscommunication. Examples of informational miscommunication included communication breakdowns among colleagues and with patients (44%), misinformation in the medical record (21%), mishandling of patients’ requests and messages (18%), inaccessible medical records (12%), and inadequate reminder systems (5%). When asked whether the patient was harmed, physicians answered affirmatively in 43% of cases in which their narratives described harms. Psychological and emotional effects accounted for 17% of physician-reported consequences but 69% of investigator-inferred consequences. CONCLUSIONS Cascade analysis of physicians’ error reports is helpful in understanding the precipitant chain of events, but physicians provide incomplete information about how patients are affected. Miscommunication appears to play an important role in propagating diagnostic and treatment mistakes. PMID:15335130

Retractions in the scientific literature: is the incidence of research fraud increasing?

PubMed

Steen, R Grant

2011-04-01

Scientific papers are retracted for many reasons including fraud (data fabrication or falsification) or error (plagiarism, scientific mistake, ethical problems). Growing attention to fraud in the lay press suggests that the incidence of fraud is increasing. The reasons for retracting 742 English language research papers retracted from the PubMed database between 2000 and 2010 were evaluated. Reasons for retraction were initially dichotomised as fraud or error and then analysed to determine specific reasons for retraction. Error was more common than fraud (73.5% of papers were retracted for error (or an undisclosed reason) vs 26.6% retracted for fraud). Eight reasons for retraction were identified; the most common reason was scientific mistake in 234 papers (31.5%), but 134 papers (18.1%) were retracted for ambiguous reasons. Fabrication (including data plagiarism) was more common than text plagiarism. Total papers retracted per year have increased sharply over the decade (r=0.96; p<0.001), as have retractions specifically for fraud (r=0.89; p<0.001). Journals now reach farther back in time to retract, both for fraud (r=0.87; p<0.001) and for scientific mistakes (r=0.95; p<0.001). Journals often fail to alert the naïve reader; 31.8% of retracted papers were not noted as retracted in any way. Levels of misconduct appear to be higher than in the past. This may reflect either a real increase in the incidence of fraud or a greater effort on the part of journals to police the literature. However, research bias is rarely cited as a reason for retraction.

What can health care marketing learn from bank marketing?

PubMed

Mindak, W A

1988-01-01

A useful technique in assessing opportunities for international marketers is called "lead lag" analysis. It suggests that one can predict developments, such as demand patterns, in one country by looking at an analogous country. Applying such a technique to the domestic scene, what could we predict about the development and application of marketing to the health care sector if we looked at an analogous service such as banking? Many experts believe that health care is following in the footsteps of banking and point to environmental similarities such as changes in government regulation, new forms of nontraditional competition, increased concern about retail sectors, and pressures on scarce resources. Are there lessons that health care marketers can learn from bankers that might help them avoid some false starts or expensive mistakes?

Photography equipment and techniques. A survey of NASA developments

1972-01-01

The Apollo program has been the most complex exploration ever attempted by man, requiring extensive research, development, and engineering in most of the sciences before the leap through space could begin. Photography has been used at each step of the way to document the efforts and activities, isolate mistakes, reveal new phenomena, and to record much that cannot be seen by the human eye. At the same time, the capabilities of photography were extended because of the need of meeting space requirements. The results of this work have been applied to community planning and ecology, for example, as well as to space and engineering. Special uses of standard equipment, modifications and new designs, as well as film combinations that indicate actual or potential ecological problems are described.

In this article the results of studies on the creation and validation of two new domestic methods for the construction of impact zones of aircraft noise and dispersion of the concentrations of pollutants in assessing the negative impact of airports are considered. Both branch methods agreed upon with the Ministry of Transport have been harmonized with ICAO (International Civil Aviation Organization) requirements. The results of full-scale measurements have confirmed the possibilities of developed software for their implementation in the formation of a common SPZ border of an airport.

Usage of Video Analysis of Traffic Conflicts for the Evaluation of Inappropriately Designed Building Elements on Intersections

NASA Astrophysics Data System (ADS)

Krivda, Vladislav; Petru, Jan

2018-04-01

Human society is constantly evolving in all areas. The transport is no exception – especially development of road transport is considerable and visible on all levels. However, it is necessary to look for tools that can harmonize economic and social progress with the full preservation of the environment for future generations. The so-called sustainable development of road transport is also closely related to the issue of creating safe transport infrastructure. For example, roads must be in compliance with technical rules on one hand and on the other one they have to be clearly understandable for all road participants (drivers, pedestrians, etc.). Unfortunately, even if the designer of transport construction meets the technical requirements, the result is a dangerous place where very frequently the accidents or traffic conflicts take place. There exist statistics of accidents, but on the contrary, there are not any statistics of traffic conflicts. And simply monitoring the traffic conflicts can lead to early detection of problematic places in road infrastructure and thus increasing the safety in the road traffic. There are many methods used for monitoring traffic conflicts. The method used in the Czech Republic is described in the submitted paper. The original method, which monitored mainly and only the behaviour of drivers and their mistakes, was innovated, so that it could be used also for evaluation of inappropriately designed building elements of road constructions. Therefore, the paper deals with the description of so-called Innovated Video Analysis of Traffic Conflicts (IVATC) and with the usage of this method for one particular example of intersection, where larger vehicles (buses, trucks, etc.) had problems with passing through it. It points out to the fact that even a relatively small change can lead to the increase of the road safety.

Challenging hierarchy in healthcare teams - ways to flatten gradients to improve teamwork and patient care.

PubMed

Green, B; Oeppen, R S; Smith, D W; Brennan, P A

2017-06-01

In healthcare, mistakes that are potentially harmful or fatal to patients are often the result of poor communication between members of a team. This is particularly important in high-risk areas such as operating theatres or during any intervention, and the ability to challenge colleagues who are in authority when something does not seem right or is clearly wrong, is crucial. Colleagues in oral and maxillofacial surgery recognised the importance of this as early as 2004, and it is now well known that failure or reluctance to challenge others who might be wrong can severely compromise a patient's safety. The Royal College of Surgeons of Edinburgh runs popular regular courses (Non-technical Skills for Surgeons, NOTSS) that teach how to ensure safety through good communication and teamwork. In this paper we introduce the concept of hierarchical challenge, and discuss models and approaches to address situations when problems arise within a team.

The dumbest mistake I ever made.

PubMed

Reichman, O Howard

2015-01-01

Life as a Neurological Surgeon is a foreboding responsibility and a gratifying opportunity. Having the confidence and trust of individuals faced with a life or death situation requires extensive training and experience. Curiosity provides the motivation to continuously seek better understanding of complex disease problems, better technology, improved diagnostic capability, and surgical skills. Solution of these challenges has been a constant process for several decades and continues to pose opportunities for progress. Early observation of results provides important information, but in many circumstances it may require long-term evaluation to fully document the benefit, or lack of benefit, for any treatment procedure. The focus of attention by the Neurological Surgeon must be on the proper immediate management of each given situation, but it is also important, and a responsibility to consider the long-term consequences or results. This presents a difficult challenge because patients move into distant places and Neurological Surgeons frequently move to accept new opportunities. It is expensive and cumbersome to retain records for many years. It is also unpredictable which patient's information will become particularly significant. It is an opportunity to describe experience with four patients to illustrate this dilemma.

Novel and transformative medical technologies of all forms have the potential to make a significant positive impact on the lives of patients and on the health care system, and one common pathway for guiding such innovations from concept through commercialization is via the formation of a company. For entrepreneurs looking to build a medical technology company, several common challenges await, including questions around how and where to raise funding. Here, we review key considerations for the formation of medical technology companies as viewed through the lens of an investor. We survey common sources of capital for early-stage companies, including grants, angel investors, and venture capital, and offer insights into how to differentiate among them to select the best partners for your start-up׳s needs. Finally, we discuss the critical components of pitching your ideas to potential investors, and offer guidance on best practices and common mistakes. We hope this primer on fundamental concepts and the various health care funding alternatives will prepare entrepreneurs to achieve their mission to improve patients׳ lives through commercialization of their medical innovations.

[Lift-trucks technological development related to driver's safety and health].

PubMed

Tartara, G

2012-01-01

The counterbalanced lift truck is a machinery characterized by an unusual behaviour. Like a lever, indeed, it is deeply affected by the change of the load condition: sometime, when a small variation of the load takes place, the position of the original load centre of gravity may change a lot. For this reason, an ordinary lapse or a small mistake when driving may lead to a dangerous situation in a so speedy way that the most skilled lift-truck operator too might be surprised. Only the technological development, often incited by binding provisions, can help him. This paper shortly shows the lift-truck evolution related to the driver's safety and health. In spite of our expectations, however, market does not seem to be interested in this development: either because its mind has been took away by other kind of problems, or because a suitable sensitization campaign did not take place.

Rule-based optimization and multicriteria decision support for packaging a truck chassis

NASA Astrophysics Data System (ADS)

Berger, Martin; Lindroth, Peter; Welke, Richard

2017-06-01

Trucks are highly individualized products where exchangeable parts are flexibly combined to suit different customer requirements, this leading to a great complexity in product development. Therefore, an optimization approach based on constraint programming is proposed for automatically packaging parts of a truck chassis by following packaging rules expressed as constraints. A multicriteria decision support system is developed where a database of truck layouts is computed, among which interactive navigation then can be performed. The work has been performed in cooperation with Volvo Group Trucks Technology (GTT), from which specific rules have been used. Several scenarios are described where the methods developed can be successfully applied and lead to less time-consuming manual work, fewer mistakes, and greater flexibility in configuring trucks. A numerical evaluation is also presented showing the efficiency and practical relevance of the methods, which are implemented in a software tool.

Suburban sprawl in the developing world: duplicating past mistakes? The case of Kuala Lumpur, Malaysia.

PubMed

Loh, Lawrence C; Brieger, William B

Newly affluent developing world cities increasingly adopt the same unfortunate low-density suburban paradigm that shaped cities in the industrialized world. Identified by a World Bank report as a "mini-Los Angeles," Kuala Lumpur is a sentinel example of the results of unrestrained sprawl in the developing world. Factors driving sprawl included government policies favoring foreign investment, "mega-projects," and domestic automobile production; fragmented governance structures allowing federal and state government influence on local planning; increasing middle-class affluence; an oligopoly of local developers; and haphazard municipal zoning and transport planning. The city's present form contributes to Malaysia's dual burden of disease, with inner-city shantytown dwellers facing communicable disease and malnutrition while suburban citizens experience increasing chronic disease, injury, and mental health issues. Despite growing awareness in city plans targeted toward higher density development, Kuala Lumpur presents a warning to other emerging economies of the financial, societal, and population health costs imposed by quickly-built suburban sprawl.

Although the recently approved Sustainable Development Goals (SDGs) explicitly mention access to water, health and education as universally guaranteed human rights, access to affordable and sufficient food is not given such recognition. The SDGs road map assumes that market mechanisms will suffice to secure nutritious and safe food for all. We question how and why the right to food has disappeared from such an international agreement and we will provide insights on the likely causes of this and the options to make good on such a regrettable omission. Analysis of political stances of relevant western stakeholders, such as the United States (US) and the European Union (EU), is also included. PMID:28588925

In this paper, we report the immediate causes of the 2008 financial crisis, in the shape of products of financial engineering associated with human greed and stupidity, and necessarily aided and abetted by the Black-Scholes-Merton model, and the mediate, and deeper, causesderived from development promoted by the scientific and technological binomial. We finally draw realistic conclusions regarding the inexorable effects that logically derive from the above causes. An important finding is that human beingsare the only animals to make the same mistake twice. The necessaryconditions are again being generated and will soon be sufficient for acrash, like the one thatcaused the 2007-08 financial crisis, to recur.

BIG DATA AND STATISTICS

Big Data brings unprecedented power to address scientific, economic and societal issues, but also amplifies the possibility of certain pitfalls. These include using purely data-driven approaches that disregard understanding the phenomenon under study, aiming at a dynamically moving target, ignoring critical data collection issues, summarizing or preprocessing the data inadequately and mistaking noise for signal. We review some success stories and illustrate how statistical principles can help obtain more reliable information from data. We also touch upon current challenges that require active methodological research, such as strategies for efficient computation, integration of heterogeneous data, extending the underlying theory to increasingly complex questions and, perhaps most importantly, training a new generation of scientists to develop and deploy these strategies.

A Proposal of Operational Risk Management Method Using FMEA for Drug Manufacturing Computerized System

NASA Astrophysics Data System (ADS)

Takahashi, Masakazu; Nanba, Reiji; Fukue, Yoshinori

This paper proposes operational Risk Management (RM) method using Failure Mode and Effects Analysis (FMEA) for drug manufacturing computerlized system (DMCS). The quality of drug must not be influenced by failures and operational mistakes of DMCS. To avoid such situation, DMCS has to be conducted enough risk assessment and taken precautions. We propose operational RM method using FMEA for DMCS. To propose the method, we gathered and compared the FMEA results of DMCS, and develop a list that contains failure modes, failures and countermeasures. To apply this list, we can conduct RM in design phase, find failures, and conduct countermeasures efficiently. Additionally, we can find some failures that have not been found yet.

The failure-tolerant leader.

PubMed

Farson, Richard; Keyes, Ralph

2002-08-01

"The fastest way to succeed," IBM's Thomas Watson, Sr., once said, "is to double your failure rate." In recent years, more and more executives have embraced Watson's point of view, coming to understand what innovators have always known: Failure is a prerequisite to invention. But while companies may grasp the value of making mistakes at the level of corporate practices, they have a harder time accepting the idea at the personal level. People are afraid to fail, and corporate culture reinforces that fear. In this article, psychologist and former Harvard Business School professor Richard Farson and coauthor Ralph Keyes discuss how companies can reduce the fear of miscues. What's crucial is the presence of failure-tolerant leaders--executives who, through their words and actions, help employees overcome their anxieties about making mistakes and, in the process, create a culture of intelligent risk-taking that leads to sustained innovation. Such leaders don't just accept productive failure, they promote it. Drawing from their research in business, politics, sports, and science, the authors identify common practices among failure-tolerant leaders. These leaders break down the social and bureaucratic barriers that separate them from their followers. They engage at a personal level with the people they lead. They avoid giving either praise or criticism, preferring to take a nonjudgmental, analytical posture as they interact with staff. They openly admit their own mistakes rather than trying to cover them up or shifting the blame. And they try to root out the destructive competitiveness built into most organizations. Above all else, failure-tolerant leaders push people to see beyond traditional definitions of success and failure. They know that as long as a person views failure as the opposite of success, rather than its complement, he or she will never be able to take the risks necessary for innovation.

The impact of generic language about ability on children's achievement motivation.

PubMed

Cimpian, Andrei

2010-09-01

Nuances in how adults talk about ability may have important consequences for children's sustained involvement and success in an activity. In this study, I tested the hypothesis that children would be less motivated while performing a novel activity if they were told that boys or girls in general are good at this activity (generic language) than if they were told that a particular boy or girl is good at it (non-generic language). Generic language may be detrimental because it expresses normative societal expectations regarding performance. If these expectations are negative, they may cause children to worry about confirming them; if positive, they may cause worries about failing to meet them. Moreover, generic statements may be threatening because they imply that performance is the result of stable traits rather than effort. Ninety-seven 4- to 7-year-olds were asked to play a game in which they succeeded at first but then made a few mistakes. Since young children remain optimistic in achievement situations until the possibility of failure is made clear, I hypothesized that 4- and 5-year-olds would not be affected by the implications of generic language until after they made mistakes; 6- and 7-year-olds, however, may be susceptible earlier. As expected, the older children who heard that boys or girls are good at this game displayed lower motivation (e.g., more negative emotions, lower perceived competence) from the start, while they were still succeeding and receiving praise. Four- and 5-year-olds who heard these generic statements had a similar reaction, but only after they made mistakes. These findings demonstrate that exposure to generic language about ability can be an obstacle to children's motivation and, potentially, their success.

The Enzymology of 2-Hydroxyglutarate, 2-Hydroxyglutaramate and 2-Hydroxysuccinamate and Their Relationship to Oncometabolites.

Many enzymes make "mistakes". Consequently, repair enzymes have evolved to correct these mistakes. For example, lactate dehydrogenase (LDH) and mitochondrial malate dehydrogenase (mMDH) slowly catalyze the reduction of 2-oxoglutarate (2-OG) to the oncometabolite l-2-hydroxyglutarate (l-2-HG). l-2-HG dehydrogenase corrects this error by converting l-2-HG to 2-OG. LDH also catalyzes the reduction of the oxo group of 2-oxoglutaramate (2-OGM; transamination product of l-glutamine). We show here that human glutamine synthetase (GS) catalyzes the amidation of the terminal carboxyl of both the l- and d- isomers of 2-HG. The reaction of 2-OGM with LDH and the reaction of l-2-HG with GS generate l-2-hydroxyglutaramate (l-2-HGM). We also show that l-2-HGM is a substrate of human ω-amidase. The product (l-2-HG) can then be converted to 2-OG by l-2-HG dehydrogenase. Previous work showed that 2-oxosuccinamate (2-OSM; transamination product of l-asparagine) is an excellent substrate of LDH. Finally, we also show that human ω-amidase converts the product of this reaction (i.e., l-2-hydroxysuccinamate; l-2-HSM) to l-malate. Thus, ω-amidase may act together with hydroxyglutarate dehydrogenases to repair certain "mistakes" of GS and LDH. The present findings suggest that non-productive pathways for nitrogen metabolism occur in mammalian tissues in vivo. Perturbations of these pathways may contribute to symptoms associated with hydroxyglutaric acidurias and to tumor progression. Finally, methods for the synthesis of l-2-HGM and l-2-HSM are described that should be useful in determining the roles of ω-amidase/4- and 5-C compounds in photorespiration in plants.

Preparations administered by inhalation make relatively high demands on the skill and knowledge of the patient in handling this form of application, for the effectivity of the therapy is inseparably linked to its faultless application. The present article aims at analysing possible mistakes in handling and at finding the most effective way of avoiding them. Several groups of patients with different previous knowledge were analysed in respect of handling skill and the influence of training on an improvement of the same; the patients' self-assessment was analysed by questioning them. Most mistakes are committed by patients whose only information consists of the contents of the package circular. Written instructions alone cannot convey sufficient information especially on how to synchronize the release operations. Major mistakes are insufficient expiration before application in 85.6% of the patients and lack of synchronisation in 55.9%, while the lowest rate of errors in respect of handling was seen in patients who had undergone training and instruction. Training in application associated with demonstration and subsequent exercise reduces the error ratio to a tolerable level. Pulverizers free from propelling gas and preparations applied by means of a spacer are clearly superior to others in respect of a comparatively low error rate. 99.3% of all patients believe they are correctly following the instructions, but on going into the question more deeply it becomes apparent that 37.1% of them make incorrect statements. Hence, practical training in application should get top priority in the treatment of obstructive diseases of the airways. The individual steps of inhalation technique must be explained in detail and demonstrated by means of a placebo dosage aerosol.(ABSTRACT TRUNCATED AT 250 WORDS)

Preventing medical errors by designing benign failures.

PubMed

Grout, John R

2003-07-01

One way to successfully reduce medical errors is to design health care systems that are more resistant to the tendencies of human beings to err. One interdisciplinary approach entails creating design changes, mitigating human errors, and making human error irrelevant to outcomes. This approach is intended to facilitate the creation of benign failures, which have been called mistake-proofing devices and forcing functions elsewhere. USING FAULT TREES TO DESIGN FORCING FUNCTIONS: A fault tree is a graphical tool used to understand the relationships that either directly cause or contribute to the cause of a particular failure. A careful analysis of a fault tree enables the analyst to anticipate how the process will behave after the change. EXAMPLE OF AN APPLICATION: A scenario in which a patient is scalded while bathing can serve as an example of how multiple fault trees can be used to design forcing functions. The first fault tree shows the undesirable event--patient scalded while bathing. The second fault tree has a benign event--no water. Adding a scald valve changes the outcome from the undesirable event ("patient scalded while bathing") to the benign event ("no water") Analysis of fault trees does not ensure or guarantee that changes necessary to eliminate error actually occur. Most mistake-proofing is used to prevent simple errors and to create well-defended processes, but complex errors can also result. The utilization of mistake-proofing or forcing functions can be thought of as changing the logic of a process. Errors that formerly caused undesirable failures can be converted into the causes of benign failures. The use of fault trees can provide a variety of insights into the design of forcing functions that will improve patient safety.

Human mistakes are still one of the main reasons of underlying regulatory affairs that in a compliance with FDA's Data Integrity and Analytical Quality by Design (AQbD) must be eliminated. To develop smooth, fast and robust methods that are free of human failures, a state-of-the-art automation was presented. For the scope of this study, a commercial software (DryLab) and a model mixture of 10 drugs were subjected to testing. Following AQbD-principles, the best available working point was selected and conformational experimental runs, i.e. the six worst cases of the conducted robustness calculation, were performed. Simulated results were found to be in excellent agreement with the experimental ones, proving the usefulness and effectiveness of an automated, software-assisted analytical method development.

Lin, Chi-Ying; Hsieh, Ping-Jung

2017-01-01

The gathering of ingredients for decoctions of traditional Chinese herbs still relies on manual dispensation, due to the irregular shape of many items and inconsistencies in weights. In this study, we developed an automatic dispensing system for Chinese herbal decoctions with the aim of reducing manpower costs and the risk of mistakes. We employed machine vision in conjunction with a robot manipulator to facilitate the grasping of ingredients. The name and formulation of the decoction are input via a human-computer interface, and the dispensing of multiple medicine packets is performed automatically. An off-line least-squared curve fitting method was used to calculate the amount of material grasped by the claws and thereby improve system efficiency as well as the accuracy of individual dosages. Experiments on the dispensing of actual ingredients demonstrate the feasibility of the proposed system.

Subject Elementary Statistics, Statistical Methods and Statistical Methods Practicum aimed to equip students of Mathematics Education about descriptive statistics and inferential statistics. The students' understanding about descriptive and inferential statistics were important for students on Mathematics Education Department, especially for those who took the final task associated with quantitative research. In quantitative research, students were required to be able to present and describe the quantitative data in an appropriate manner, to make conclusions from their quantitative data, and to create relationships between independent and dependent variables were defined in their research. In fact, when students made their final project associated with quantitative research, it was not been rare still met the students making mistakes in the steps of making conclusions and error in choosing the hypothetical testing process. As a result, they got incorrect conclusions. This is a very fatal mistake for those who did the quantitative research. There were some things gained from the implementation of reflective pedagogy on teaching learning process in Statistical Methods and Statistical Methods Practicum courses, namely: 1. Twenty two students passed in this course and and one student did not pass in this course. 2. The value of the most accomplished student was A that was achieved by 18 students. 3. According all students, their critical stance could be developed by them, and they could build a caring for each other through a learning process in this course. 4. All students agreed that through a learning process that they undergo in the course, they can build a caring for each other.

Castro, Luis A; Favela, Jesus; Garcia-Peña, Carmen

2014-11-01

The transition from paper to electronic-based records in the healthcare industry has posed several challenges to conventional medical practices. The introduction of technology in day-to-day medical and nursing practices deserves careful consideration. In this work, we report the results of a controlled experiment to compare nurses' consultation in emergency calls in six different conditions. We studied the effect that the type of communication media (face-to-face, telephone, videoconference) and type of nursing protocol media (paper-based, electronic-based) can have on consultation time, mistakes made, pauses during consultation, eye contact, and efficacy of the consultation. We found that the type of communication media has an effect on consultation time; on average, fewer mistakes were made during telephone-based consultations; for eye contact, there were significantly fewer eye contacts during face-to-face than during videoconference consultations; finally, the type of communication media or protocol media did not have any effect in the efficacy of the consultation.

Performance Acceleration on Production Machines Using the Overall Equipment Effectiveness (OEE) Approach

2016-01-01

Mistakes during working can trigger a decrease in production level that may lead financial loss to the company. The factors that affect the mistakes are called losses, such as breakdown loss, set up/ adjustment loss, idling and minor stoppage loss, reduced speed loss, reduced yield loss, and rework loss. The objective of the research is to accelerate the performance of the JSW 330T machine in PT. YogyaPresisiTehnikatamaIndustri. JSW 330T is a machine that has the highest downtime numbers. The method for measuring the effectiveness is using the Overall Equipment Effectiveness (OEE). The results of the research show that the JWQ 330T has average rate of the effectiveness (OEE) of 52.66%, availability ratioof 73.43%, performance efficiency rate of 83.58% and quality rate of 84.6%. From the six big losses calculation, the factor that affects the most on the low score of OEE is the breakdown loss which is 58.85% with total time loss of 929.65 hours in a year.

Human operator response to error-likely situations in complex engineering systems

NASA Technical Reports Server (NTRS)

Morris, Nancy M.; Rouse, William B.

1988-01-01

The causes of human error in complex systems are examined. First, a conceptual framework is provided in which two broad categories of error are discussed: errors of action, or slips, and errors of intention, or mistakes. Conditions in which slips and mistakes might be expected to occur are identified, based on existing theories of human error. Regarding the role of workload, it is hypothesized that workload may act as a catalyst for error. Two experiments are presented in which humans' response to error-likely situations were examined. Subjects controlled PLANT under a variety of conditions and periodically provided subjective ratings of mental effort. A complex pattern of results was obtained, which was not consistent with predictions. Generally, the results of this research indicate that: (1) humans respond to conditions in which errors might be expected by attempting to reduce the possibility of error, and (2) adaptation to conditions is a potent influence on human behavior in discretionary situations. Subjects' explanations for changes in effort ratings are also explored.

When faced with a problem or choice, humans can use two different strategies: “cognitive reflectivity,” which involves slow responses and fewer mistakes, or “cognitive impulsivity,” which comprises of quick responses and more mistakes. Different individuals use these two strategies differently. To our knowledge, no study has directly investigated the brain regions involved in reflectivity–impulsivity; therefore, this study focused on associations between these cognitive strategies and the gray matter structure of several brain regions. In order to accomplish this, we enrolled 776 healthy, right-handed individuals (432 men and 344 women; 20.7 ± 1.8 years) and used voxel-based morphometry with administration of a cognitive reflectivity–impulsivity questionnaire. We found that high cognitive reflectivity was associated with greater regional gray matter density in the ventral medial prefrontal cortex. Our finding suggests that this area plays an important role in defining an individual’s trait associated with reflectivity and impulsivity. PMID:25803809

Music Memory Following Short-term Practice and Its Relationship with the Sight-reading Abilities of Professional Pianists.

PubMed

Aiba, Eriko; Matsui, Toshie

2016-01-01

This study investigated the relationship between the ability to sight-read and the ability to memorize a score using a behavioral experiment. By measuring the amount of memorization following short-term practice, we examined whether better sight-readers not only estimate forthcoming notes but also memorize musical structures and phrases with more practice. Eleven pianists performed the music first by sight-reading. After a 20-minute practice, the participants were asked to perform from memory without any advance notice. The number of mistakes was used as an index of performance. There were no correlations in the numbers of mistakes between sight-reading and memory trial performance. Some pianists memorized almost the entire score, while others hardly remembered it despite demonstrating almost completely accurate performance just before memory trial performance. However, judging from the participants' responses to a questionnaire regarding their practice strategies, we found auditory memory was helpful for memorizing music following short-term practice.

Parapraxes in the plays of William Shakespeare.

PubMed

Mahon, E

2000-01-01

Parapraxes in the psychopathology of everyday life are "mistakes" that reveal the workings of the unconscious. (Obviously they existed before Freud's time, but it was Freud who gave them a name and dissected their complex psychological meanings.) When they occur in a great work of art (as in Shakespeare's plays) they are obviously not "mistakes" at all but carefully planted details of the artist's over-all aesthetic conception. Just as fictional dreams, as in Jensen's Gradiva, seem to follow the rules of nocturnal dream process and can be subjected to psychoanalytic scrutiny, fictional parapraxes are doubly interesting because they not only express the inwardness of a protagonist but reveal something of the writer's aesthetic method as well. This paper attempts to address these double points of entry into the mystery of Shakespeare's plays, posing the question, "Can the seemingly trivial or irrelevant (a handful of parapraxes in 38 plays) shed any light on the most complex characters in Western literature and the extraordinary mind of their creator?"

Cystic fibrosis: myths. mistakes, and dogma.

PubMed

Rubin, Bruce K

2014-03-01

As a student I recall being told that half of what we would learn in medical school would be proven to be wrong. The challenges were to identify the incorrect half and, often more challenging, be willing to give up our entrenched ideas. Myths have been defined as traditional concepts or practice with no basis in fact. A misunderstanding is a mistaken approach or incomplete knowledge that can be resolved with better evidence, while firmly established misunderstandings can become dogma; a point of view put forth as authoritative without basis in fact. In this paper, I explore a number of myths, mistakes, and dogma related to cystic fibrosis disease and care. Many of these are myths that have long been vanquished and even forgotten, while others are controversial. In the future, many things taken as either fact or "clinical experience" today will be proven wrong. Let us examine these myths with an open mind and willingness to change our beliefs when justified.

Irreversible and reversible components in the genesis of hypertension by sodium chloride (salt).

PubMed

Tekol, Yalcin

2008-01-01

Despite the abundant studies and overwhelming evidences demonstrating the essential role of salt (sodium chloride) for developing "essential" hypertension (EH), the controversies about salt-hypertension (HT) relations are still continuing. One of important mistakes in this topic is assuming that the HT-producing effect of salt is reversible. The present paper explains the complex nature of salt-HT relations. The deduction was made basing on the studies which investigate the relations between salt and HT. Animal experiments show that HT-producing effect of salt contains irreversible and reversible components. The existence of irreversible component manifests itself in this way: the blood pressure (BP) does not recede to the natural values despite removing of salt exposure. The proportion of BP decreasing after salt exposure termination belongs to the reversible component. Available evidences indicate that the irreversible component is developed in utero, during suckling and, generally, in prepubertal period secondary to salt exposure, however, if the salt exposure extends over more than one period, the HT may be intensified. The consequences of salt exposure during early life of human beings have not been investigated as detailed as in experimental animals, however, there are some clinical trials and epidemiological observations indicating that, similar to experimental animals, irreversible and reversible components are also developed in man during the genesis of HT. By the introduction of irreversible and reversible components notion, some obscured items on salt-HT relations can be clarified. For example, some intervention studies could not find dramatic relations between salt and HT, because these interventions modify only the reversible component, but irreversible component remains unchanged. As a result, salt exposure is detrimental for each period of life. For eradication of HT, it is prerequisite to prevent all individuals (especially pregnant or lactating women, and children) from salt exposure. In this condition, the new generation will be free from HT.

It's Time for an Adventure

In recent years, studies have repeatedly illustrated the significance of children seeing themselves reflected in careers and cultures that they may not typically identify with. The current lack of diversity in accessible media, however, limits the potential for self-reflection from children of different socioeconomic, racial, and gender identity backgrounds. This isolates substantial sections of our population from experiencing these moments of recognition and inspiration. As scientists in a rapidly evolving field that requires diversity in perspective and ideas, it is incumbent upon us to innovate new ways to engage with these future generations in the pursuit of inspiring future earth scientists. Inspired by the work of others (e.g. Doc McStuffins, The Sandwich Swap) and through a successful crowdfunding campaign, I was able to develop a project which integrates children's love of adventure with foundational critical thinking skills. That project is MD and Finn. MD and Finn is a self-written/published children's book series which was developed to address the lack of diversity in children's literature. MD is a little girl who continuously explores, discovers, and builds the world around her with her best friend, Finn the fox. They encourage one another to ask questions, brainstorm, make mistakes, and learn from absolutely everything. While the primary goal of the series is to create a character in which young girls can see themselves solving problems, learning from mistakes, and enjoying the little pieces of science in daily life, as the project progresses, characters from different races, ethnicities, gender identities, religions, and disabilities are purposefully introduced. In bringing these books to life, I have been given the unique opportunity to regularly engage with classrooms and families who may be meeting an actual scientist for the very first time. For a few young girls, they may also finally be seeing just a little bit of themselves - in a lab coat. To learn more, please visit www.MDandFinn.com.
