    Wrong-way driving is a phenomenon that mainly happens on motorways. Although the number of wrong-way crashes is relatively limited, their consequences are much more severe than the consequences of other motorway injury crashes. The groups most often causing wrong-way driving accidents are young, inexperienced drivers and elderly drivers. Alcohol often plays a large role with the young; processing (visual) information is especially a problem with the elderly. Improved road signs and infrastruc...

  4. Why Is Cheating Wrong?

    2010-01-01

    Since cheating is obviously wrong, arguments against it (it provides an unfair advantage, it hinders learning) need only be mentioned in passing. But the argument of unfair advantage absurdly takes education to be essentially a race of all against all; moreover, it ignores that many cases of unfair (dis)advantages are widely accepted. On the other…

  5. Experiment, right or wrong

    CERN Document Server

    Franklin, Allan

    2008-01-01

    In Experiment, Right or Wrong, Allan Franklin continues his investigation of the history and philosophy of experiment presented in his previous book, The Neglect of Experiment. In this new study, Franklin considers the fallibility and corrigibility of experimental results and presents detailed histories of two such episodes: 1) the experiment and the development of the theory of weak interactions from Fermi's theory in 1934 to the V-A theory of 1957 and 2) atomic parity violation experiments and the Weinberg-Salam unified theory of electroweak interactions of the 1970s and 1980s. In these episodes Franklin demonstrates not only that experimental results can be wrong, but also that theoretical calculations and the comparison between experiment and theory can also be incorrect. In the second episode, Franklin contrasts his view of an "evidence model" of science in which questions of theory choice, confirmation, and refutation are decided on the basis of reliable experimental evidence, with that proposed by the ...

  6. Where physics went wrong

    CERN Document Server

    Lavenda, Bernard

    2015-01-01

    The book points out what has gone wrong with physics since Einstein's formulation of this theory of general relativity a century ago. It points out inconsistencies and fallacies in the standard model of the big bang and the inflationary scenario which was supposed to have overcome those shortcomings, the evolution of string theory from a theory of the strong interaction to a theory of gravitation and quantum mechanics which has not produced a single verifiable prediction, and what it has accomplished is reaffirming wrong results like the entropy of a black hole, which is not an entropy at all. There have even been attempts to demote gravity to an emergent phenomenon with catastrophic effects. We know exactly what happened at 10-34 seconds after the big bang, but do not know how fast gravity propagates, whether gravitational waves exist, and what are the limits of Newton's law. Attempts to rectify this are the prediction of dark energy/matter, which has never been observed nor ever will, and MOND. The latter i...

  7. Wrong for the Right Reasons

    CERN Document Server

    Buchwald, Jed Z

    2005-01-01

    The rapidity with which knowledge changes makes much of past science obsolete, and often just wrong, from the present's point of view. We no longer think, for example, that heat is a material substance transferred from hot to cold bodies. But is wrong science always or even usually bad science? The essays in this volume argue by example that much of the past's rejected science, wrong in retrospect though it may be - and sometimes markedly so - was nevertheless sound and exemplary of enduring standards that transcend the particularities of culture and locale.

  8. Analysing the Wrongness of Killing

    2014-01-01

    This article provides an in-depth analysis of the wrongness of killing by comparing different versions of three influential views: the traditional view that killing is always wrong; the liberal view that killing is wrong if and only if the victim does not want to be killed; and Don Marquis‟ future...... of value account of the wrongness of killing. In particular, I illustrate the advantages that a basic version of the liberal view and a basic version of the future of value account have over competing alternatives.

    A recent decision of the French supreme court has recognised what has been termed in the common law system, a "wrongful life" action. Intentionally provocative, the decision shows how the desire for equitable or "corrective" justice poses a threat not only to established legal principles on civil liability, but also to the ethical framework in which both the medical and legal professions must operate.

  12. Wrongful birth and wrongful conception: the legal and moral issues.

    Science.gov (United States)

    Donovan, P

    1984-01-01

    This is a summary review of the various legal, moral and policy issues that have contributed to changes in the courts' enactment of legislation on wrongful-birth and wrongful-conception suits in the United States. Both cases represent the Supreme Court's recognition of personal injury claims by parents who have received inadequate medical care that has led to the birth of an imparied or unplanned child. In wrongful-birth cases, the parents assert that if they had received proper genetic counseling or testing, the child's birth could have been avoided. Parents involved in litigation of this type argue that the doctor's negligence prevented them from making such decisions, and that they should be compensated for the financial hardships and emotional suffering they experience as a result of his mistake. In such claims, the physician is charged with malpractice, an aspect of the law of torts which gives the injured party the right to seek financial compensation for that injury. Generally, state courts have allowed parents to recover the costs of medical care and of training and treatment for the handicapped child. Similarly, state courts now routinely recognize the wrongful-conception claims of parents who seek damages from a doctor or pharmacist after the birth of a healthy but unplanned child, born as a result of a failed sterilization or abortion. The recognition of wrongful-birth claims is closely linked to the legalization of abortion and the refinement of diagnostic tests, e.g., amniocentesis, that can detect many genetic diseases before birth. Such legislation is due to changes i opinion since 1967 and was strongly reinforced by the Supreme Court's concurrent decisions that it is a couples' constitutional right to decide whether or not to have a child and whether or not to use contraceptives to prevent conception. The major controversy today in this type of claims is over the amount of damages the parents may recover. Some states have passed legislation barring

  14. What if physics is wrong?

    Science.gov (United States)

    Tu, Zhoudunming

    2011-11-01

    Physics, an experiment-based science, seems to be the most appropriate subject in how to explain the inner workings of the world. We respect physics because it is based on facts that are perceived by our observations. However, what if we are not seeing the entire truth we seek? What if our observations are founded on sandy foundations? As humans, we desire to know what the truth is. Rene Descartes, a mathematician, philosopher, and physicist asked this question: what is the absolute truth in our universe? I want to solve the same puzzle. Many people believe that physics will reveal the truth of our universe. But, what if physics is wrong?

  15. Righting wrongs and reforming rights.

    Science.gov (United States)

    Ivey, Laurie C

    2014-03-01

    Discusses issues faced by LGBT people, such as a lack of equal civil rights and the need for extra legal and financial protection for families because partners cannot be married. The author notes that, in our society, it is no longer acceptable to be racist, but it is still okay to be homophobic. The many campaigns against gay marriage and efforts in the legislature to prevent change toward equal civil rights and protections are prime examples. In our current political climate, two things are very clear: (a) homophobia is freely tolerated and (b) the times are changing as we inch closer to equal rights every day. We are "righting wrongs and reforming rights."

  16. The possibility of compensation for damages in cases of wrongful conception, wrongful birth and wrongful life. An Estonian perspective.

    Science.gov (United States)

    Sõritsa, Dina; Lahe, Janno

    2014-04-01

    While case law in cases of wrongful conception, wrongful birth and wrongful life is completely missing in Estonia, this article is aimed at providing possible solutions under Estonian law to some of the legally complex problems that these cases contain. Through the analysis of Estonian, German and U.S. legal literature and case law, the article is mainly focused on proposing some solutions to the legal problems concerning compensable damage, but also explains the Estonian legal framework of the contractual and delictual basis for compensation for the damages. The application of several grounds for the possibility of limiting the compensation in the afore-mentioned cases are analysed.

  17. Non-pecuniary damages for wrongful dismissal

    Directory of Open Access Journals (Sweden)

    Obradović Goran

    2014-01-01

    Full Text Available One of the consequences of wrongful dismissal is the damage sustained by the unlawfully dismissed person. It may occur in two forms: as material damage and as non- non-material damage. In the event of a wrongful termination of employment, material damage is reflected in loss of earnings and other income that could have been received if there had been no wrongful dismissal, as well as in failure to pay contributions for mandatory social insurance. The compensation for material damage (pecuniary damages for wrongful termination of employment is not a matter of controversy in Serbian theory and practice. Besides material damage, wrongful dismissal may also cause non-material damage. In the spirit of Serbian law, it may be reflected in sustained mental pain (for the violation of dignity and reputation, and/or violation of one's personality rights and sustained fear. The right to claim compensation for non-material damage (non-pecuniary damages is a subject matter of debate particularly in legal practice. The major issue of dispute in wrongful dismissal cases is the question whether it is necessary to award non-pecuniary damages for sustained mental pain or distress (in addition to pecuniary damages, or whether the rendered court decision (establishing that the dismissal has been wrongful and that the employee shall return to work is a sufficient satisfaction. Inter alia, the same question has been posed in respect of the cases involving the unlawfully dismissed judges and prosecutors. The authors advocate the standpoint that a wrongful act cannot be fully remedied in all cases only by awarding declaratory relief and returning the employee to work. Hence, non-pecuniary damages should be awarded as compensation for non-material damage caused by wrongful termination or dismissal whenever it is justified by the circumstances of the case.

    To describe the factors pertaining to medication being administered to the wrong patient and to describe how patient identification is mentioned in wrong-patient incident reports. Although patient identification has been given high priority to improve patient safety, patient misidentifications occur, and wrong-patient incidents are common. A descriptive content analysis. Incident reports related to medication administration (n = 1,012) were collected from two hospitals in Finland between 1 January 2013-31 December 2014. Of those, only incidents involving wrong-patient medication administration (n = 103) were included in this study. Wrong-patient incidents occurred due for many reasons, including nurse-related factors (such as tiredness, a lack of skills or negligence) but also system-related factors (such as rushing or heavy workloads). In 77% (n = 79) of wrong-patient incident reports, the process of identifying of the patient was not described at all. There is need to pay more attention to and increase training in correct identification processes to prevent wrong-patient incidents, and it is important to adjust system factors to support nurses. Active patient identification procedures, double-checking and verification at each stage of the medication process should be implemented. More attention should also be paid to organisational factors, such as division of work, rushing and workload, as well as to correct communication. The active participation of nurses in handling incidents could increase risk awareness and facilitate useful protection actions. © 2017 John Wiley & Sons Ltd.

    Full Text Available Hoy día, las personas buscan aprovechar su tiempo libre en actividades solidarias. Una de las opcionespor las que más a menudo se inclinan son los voluntariados, tal como se señala en el Informe sobre el estado del voluntariado en el mundo para 2011, de las Naciones Unidas. La poca información concreta y disponible, así como la escasez de referentes acerca del voluntariado tanto a escala nacional como desde el ámbito universitario, es el aspecto más notorio a la hora de hacer un análisis de la realidad de este tipo de movimientos. Pese a ello, algunas fuentes rigurosas y actualizadas nos permiten aproximarnos a esta realidad e identificar algunos de los retos y las tendencias que deben plantearse en dicho ámbito para su futuro. El objetivo de la presente revisión bibliográfica es conocer el estado actual de la realidad de los voluntariados universitarios tomando en cuenta los ámbitos de carácter internacional y nacional, para, con ello, orientar mejor la experiencia extracurricular que se ha hecho con el voluntariado Proceder , del Programa Ciencias del Deporte y la Recreación de la Universidad Tecnológica de Pereira.

    2007-07-01

    Infants in the neonatal intensive care unit are at particular risk from clinical errors because of their fragility and vulnerability, as well as the complex nature of medication and other treatment regimes. Wrong route errors have been well documented, particularly related to enteral nutrition and medication. Published guidance for preventing such errors should inform changes in practice at the local level. In 2005, the Regional Neonatal Intensive Care Unit at the University Hospital of Wales Cardiff undertook a change in clinical practice to improve standards of care for all babies requiring enteral nutrition and medication, thus reducing the risk of a wrong route error. A routine revision of departmental policy resulted in a review of available evidence to inform the practice changes. Colour-coded enteral/oral syringes with a new style nasogastric tube were introduced. By promoting best practice through networking with other colleagues, staff have worked towards standardising the delivery of care in order to minimise the risk wrong route errors.

    In my essay, Why abortion is immoral, I criticised discussions of the morality of abortion in which the crucial issue is whether fetuses are human beings or whether fetuses are persons. Both argument strategies are inadequate because they rely on indefensible assumptions. Why should being a human being or being a person make a moral difference? I argued that the correct account of the morality of abortion should be based upon a defensible account of why killing children and adults is wrong. I claimed that what makes killing us wrong is that our premature deaths deprive us of our futures of value, that is, the goods of life we would have experienced had we survived. This account of the wrongness of killing explains why killing is one of the worst of crimes and how killing greatly harms the victim. It coheres with the attitudes of those with cancer or HIV facing premature death. It explains why we believe it is wrong to kill infants (as personhood theories do not). It does not entail that it wrongs a human being to end her life if she is in persistent vegetative state or if her future must consist only of unbearable physical suffering and she wants to die (as sanctity of human life theories do not). This account of the wrongness of killing implies (with some defensible additional assumptions) that abortion is immoral because we were fetuses once and we know those fetuses had futures of value. Mark Brown claims that this potential future of value account is unsound because it implies that we have welfare rights to what we need to stay alive that most people would reject. I argue that Brown is incorrect in two ways: a welfare right to what we need to stay alive is not directly implied by my account and, in addition, most of us do believe that dependent human beings have substantial welfare rights to what they need to stay alive. Brown argues that depriving us of a future of value of which we have mental representations both is a better explanation of the wrongness of

    Full Text Available What is propaganda and what is wrong with it? This may be the main question when studying this complex phenomenon. In this article we shall try to give an answer to this question and to find the most appropriate definition for this disputed concept. Nowadays, propaganda has a negative connotation and usually it is used to discredit somebody’s speech or actions, by implying that he is both illogical and unethical. But propaganda wasn’t seen always like that! In order to give an objective definition of this concept, it is very important for us to understand first what exactly happened with this word throughout history.

  5. Patient safety: reducing the risk of wrong tooth extraction.

    Science.gov (United States)

    Cullingham, P; Saksena, A; Pemberton, M N

    2017-05-26

    Over recent years there has been an increased emphasis on improving patient safety in all branches of medicine, with reducing wrong tooth extraction being a priority in dentistry. The true incidence of wrong tooth extraction is unknown but it is considered an avoidable harm and is a significant source of dental litigation. Interventions to reduce wrong tooth extraction include educational programmes encompassing human factor training, patient assisted identification, the use of checklists, marking of surgical sites and implementation of patient safety guidelines. Identified risk factors which make wrong tooth extraction more likely include; suboptimal checks and/or cross checking of relevant clinical information, unclear diagnosis, unclear documentation, ambiguity regarding notation of molar teeth, orthodontic extractions, and extractions where there are multiple carious teeth and extractions in the mixed dentition. Accurate and timely reporting of wrong tooth extraction incidents followed by analysis and sharing of findings together with implementation of improved practice will help to minimise risks of wrong tooth extraction.

    Prior work suggests that receiving feedback that one's response was correct or incorrect (right/wrong feedback) does not help learners, as compared to not receiving any feedback at all (Pashler, Cepeda, Wixted, & Rohrer, 2005). In three experiments, we examined the generality of this conclusion. Right/wrong feedback did not aid error correction, regardless of whether subjects learned facts embedded in prose (Exp. 1) or translations of foreign vocabulary (Exp. 2). While right/wrong feedback di...

    The NHS in England has identified several adverse incidents that involve patients, including operations done at the wrong site, as "never" events. We examined published data from the period April 2012 to October 2015 and found that "wrong tooth/teeth removed" is the most common "wrong site" event, and accounted for between 20% and 25% of wrong site surgery never events, and 6% - 9% of all "never" events. All "wrong tooth/teeth removed" events seem to have been reported only by hospitals or Community Trusts. It is important to find out how these events are recorded and to find ways to prevent them.

  9. Why is the ethics of euthanasia wrong?

    Science.gov (United States)

    Narbekovas, Andrius; Meilius, Kazimieras

    2004-01-01

    Human beings are made in the image and likeness of God and are therefore of intrinsic worth or value, beyond all prices. Almost all Christian pro-life arguments spring from the fountain of personal dignity. Euthanasia would make moral sense only if it were possible to say, morally, that this dignity had vanished. To commit euthanasia is to act with the specific intention that somebody should be nobody. This is the fundamental error of all immorality in human relations. To commit euthanasia is to fail to see the intrinsic worth or dignity of the person. The judgement that what has worth, intrinsically, somehow does not have worth, is both logically and morally wrong. The ethics of euthanasia is based on dualistic anthropology and wrong moral presuppositions underlying the defence of euthanasia, namely, proportionalism and consequentialism. The basic claim of proponents of the ethics of euthanasia is that human persons are consciously experiencing subjects whose dignity consists of their ability to made choices and to determine their own lives. Bodily life, according to them, is a condition for personal life because without bodily life one cannot be a consciously experiencing subject. It means that bodily life is distinct from personal life. Thus, the body and bodily life are instrumental goods, goods for the person, not goods of the person. It thus follows that there can be such a thing as a life not worth living--one can judge that bodily life itself is useless or burdensome, and when it is, the person, i.e., the consciously experiencing subject, is at liberty to free himself of this useless burden. Today a key in fighting euthanasia and assisted suicide is better care for the sick and dying. The dignity of the sick cannot be erased by illness and suffering. Such procedures are not private decisions; they affect the whole society. Death with dignity, in the end, is the realisation that human beings are also spiritual beings. We have to promote the way of caring for

  14. Don't hire the wrong CEO.

    Science.gov (United States)

    Bennis, W; O'Toole, J

    2000-01-01

    A disturbing trend is going on in corporate America--CEO churning. Top executives are rapidly coming and going, keeping their jobs for increasingly shorter periods of time. The reason? Most boards are so unclear about the definition of leadership, they are picking the wrong people. CEO churning needn't be, say leadership experts Warren Bennis and James O'Toole. Boards can reverse the trend by following several guidelines. First, boards must come to a shared, accurate definition of leadership. Simply put, leaders must be able to move human hearts--to challenge people and make them want to scale steep peaks. Second, boards should strengthen the CEO selection process by resolving strategic and political conflicts amongst themselves. An agreed-upon strategic direction will make choosing the CEO with the right vision for the company that much easier and can clarify the job for the new CEO. Third, the board needs to measure every CEO candidate's soft qualities. Economic measures are important, but integrity, the ability to provide meaning, and the talent for creating other leaders are critical. Fourth, boards should beware of candidates who act like CEOs. Charisma and glossy pitches can be enticing, but they're rarely the stuff of true leadership. Fifth, boards should accept that real leaders will more than likely overturn the status quo. Sixth, boards need to know that insider heirs usually aren't apparent, and finally, boards should always avoid making a hasty decision. Hiring the right CEO is a slow process at best. Ultimately, the surest way for boards to pick the right CEO is to cultivate and nurture talent in the making.

    Full Text Available La evolución de la responsabilidad civil ha llevado a la aparición de nuevas pretensiones de reparación de daños. En este trabajo se analizan dos de ellas, las acciones de wrongful birth y wrongful life, en las que se plantea la posibilidad de calificar la vida como daño ante el nacimiento de un niño afectado por enfermedades o malformaciones de las que no fueron informados los progenitores antes de la concepción o durante el embarazo. Este análisis se aborda desde una idea de continuidad en la aplicación de la institución de la responsabilidad civil, tratando de comprobar si concurren los presupuestos de la misma, sobre la idea de que sólo en caso afirmativo puede exigirse una indemnización. Desde esta perspectiva, los principales obstáculos a estas acciones son el daño reclamado y la imputación objetiva del mismo al profesional sanitario cuyo comportamiento sólo produjo el defecto en la información recibida por los progenitores

This is accomplished by forming a cost function composed of a scalar measure of error between desired and achievable eigenvectors and a scalar measure of gain magnitude, determining analytical expressions for the gradients, and solving for the optimal solution by numerical iteration. For this development the scalar measure of gain magnitude is chosen to be a weighted sum of the squares of all the individual elements of the feedback gain matrix. An example is presented to demonstrate the method. In this example, solutions yielding achievable eigenvectors close to the desired eigenvectors are obtained with significant reductions in gain magnitude compared to a solution obtained using a previously developed eigenspace (eigenstructure) assignment method.

    An important task of a manager is to motivate her subordinates. One way in which a manager can give incentives to junior employees is through the assignment of tasks. How a manager allocates tasks in an organization, provides information to the junior employees about his ability. Without coaching from a manager, the junior employee only has information about his past performance. Based on his past performance, a talented junior who has performed a difficult task sometimes decides to leave the...

    Full Text Available Students can experience first hand through interactive assignments what is involved in teaching an online course. Most students develop a whole new appreciation for the student learning process. Faculty are beginning to realize that online instruction is more than a series of readings posted to a course management system. This paper summarizes the faculty member's instructional strategies involved when creating student interaction assignments. The paper also summarizes the assignments, discussion board, and trends in education from the student's perspective. In summary, it concludes with the faculty's overall perspective concerning these assignments and how the assignments could be more effective for the student.

    Can the conception of a child ever constitute damage recoverable in law? This article considers the liability of healthcare practitioners for failing to prevent a pregnancy. Developments leading to the recognition of wrongful pregnancy as a cause of (legal) action in South Africa (SA), are briefly outlined. The salient points of the relevant judgments by SA courts are set out to expose the rationale underlying the judgments and to highlight that recognition of liability for wrongful pregnancy resulted from an application of fair and equitable principles of general application. Conduct that could expose practitioners to liability is identified from reported cases and inferred from general principles laid down in case law.

  11. Psychopaths know right from wrong but don’t care

    2010-01-01

    Adult psychopaths have deficits in emotional processing and inhibitory control, engage in morally inappropriate behavior, and generally fail to distinguish moral from conventional violations. These observations, together with a dominant tradition in the discipline which sees emotional processes as causally necessary for moral judgment, have led to the conclusion that psychopaths lack an understanding of moral rights and wrongs. We test an alternative explanation: psychopaths have normal understanding of right and wrong, but abnormal regulation of morally appropriate behavior. We presented psychopaths with moral dilemmas, contrasting their judgments with age- and sex-matched (i) healthy subjects and (ii) non-psychopathic, delinquents. Subjects in each group judged cases of personal harms (i.e. requiring physical contact) as less permissible than impersonal harms, even though both types of harms led to utilitarian gains. Importantly, however, psychopaths’ pattern of judgments on different dilemmas was the same as those of the other subjects. These results force a rejection of the strong hypothesis that emotional processes are causally necessary for judgments of moral dilemmas, suggesting instead that psychopaths understand the distinction between right and wrong, but do not care about such knowledge, or the consequences that ensue from their morally inappropriate behavior.

    The production of wrong sign charmed mesons b -> Dbar_(s)X, D_(s) = (D0, D+, Ds), is studied using the data collected by the DELPHI experiment in the years 1994 and 1995. Charmed mesons in Z -> bbbar events are exclusively reconstructed by searching for the decays D0 -> K-pi+, D+ -> K-pi+pi+ and D+_s -> phipi+ -> K+K-pi+. The wrong sign contribution is extracted by using two discriminant variables: the charge of the b-quark at decay time, estimated from the charges of identified particles, and the momentum of the charmed meson in the rest frame of the b-hadron. The inclusive branching fractions of b-hadrons into wrong sign charm mesons are measured to be: B(b -> Dbar0X) + B(b -> D^- X) = (9.3+- 1.7(stat) +- 1.3(syst) +- 0.4(B))%, B(b -> D^-_s X) = (10.1 +- 1.0(stat) +- 0.6(syst) +- 2.8(B))% where the first error is statistical, the second and third errors are systematic.

    Full Text Available The paper concerns the role of intentionality in reasoning about wrong doing. Anthropologists have claimed that, in certain non-western societies, people ignore whether an act of wrong doing is committed intentionally or accidentally. To examine this proposition, we look at the case of Madagascar. We start by analyzing how Malagasy people respond to incest, and we find that in this case they do not seem to take intentionality into account: catastrophic consequences follow even if those who commit incest are not aware that they are related as kin; punishment befalls on innocent people; and the whole community is responsible for repairing the damage. However, by looking at how people reason about other types of wrong doing, we show that the role of intentionality is well understood, and that in fact this is so even in the case of incest. We therefore argue that, when people contemplate incest and its consequences, they simultaneously consider two quite different issues: the issue of intentionality and blame, and the much more troubling and dumbfounding issue of what society would be like if incest were to be permitted. This entails such a fundamental attack on kinship and on the very basis of society thatissues of intentionality and blame become irrelevant. Using the insights we derive from this Malagasy case study, we re-examine the results of Haidt’s psychological experiment on moral dumbfoundedness, which uses a story about incest between siblings as one of its test scenarios. We suggest that the dumbfoundedness that was documented among North American students may be explained by the same kind of complexity that we found in Madagascar. In light of this, we discuss the methodological limitations of experimental protocols, which are unable to grasp multiple levels of response. We also note the limitations of anthropological methods and the benefits of closer cross-disciplinary collaboration.

    The need for fresh water supplies in many parts of the globe has given a great impetus to the study of the desalting of sea-water. Research into this problem has been very varied. Although it is possible in the more-or-less near future that methods based on freezing may be developed, only evaporation methods have industrial applications at the present time. Amongst the many techniques using this method, the most favorably placed installations from the technical and economic points of view are those based on multiple effects and wall-less heat transfer. We have defined the characteristics of a wall-less evaporation process using the various factors involved in this evaporation: energy source, corrosion, furring, heat transfer, maximum temperature, etc... The unit considered in this work has a daily output of 100,000 m{sup 3}, and makes use of the multi-stage technique with an organic heat-carrier. The maximum temperature of the first stage is 150 deg C and the evaporation factor is 0.4. After the description of the process and, the calculation of the equipment, an economic estimate is given of the cost-price : 1.49 F/m{sup 3}. It is likely that more detailed study of the process (technique, equipment and energy consumed) should make it possible to obtain a significant improvement in the process and to reduce the price to 1 F/m{sup 3}.

    2013-09-01

    It has been argued that voluntary euthanasia (VE) and physician-assisted suicide (PAS) are morally wrong. Yet, a gravely suffering patient might insist that he has a moral right to the procedures even if they were morally wrong. There are also philosophers who maintain that an agent can have a moral right to do something that is morally wrong. In this article, I assess the view that a suffering patient can have a moral right to VE and PAS despite the moral wrongness of the procedures in light of the main argument for a moral right to do wrong found in recent philosophical literature. I maintain that the argument does not provide adequate support for such a right to VE and PAS.

    Full Text Available This paper is designed to discover legal rules addressing insolvency trading in three jurisdictions: England and Wales, Russia and the USA. Originally it was a master’s dissertation written under supervision of Ms. Sarah Paterson, who was extremely helpful and patient. The key jurisdiction for the research is England and Wales, whose wrongful trading provision apparently was the very first insolvency regulation in the field. Here, we will give particular attention to the factual circumstances of insolvency trading and research how the concept of wrongful trading addresses them. The next question will be how the American concept of deepening insolvency and the Russian concept of subsidiary liability are comparable with wrongful trading. Later, we will focus on the functions that should be performed by the regulations. Also, the effectiveness of wrongful trading and similar overseas provisions will be examined. Finally, this paper attempts to find obstacles to the wide application of wrongful trading provision.

    Sadigh, Gelareh; Loehfelm, Thomas; Applegate, Kimberly E; Tridandapani, Srini

    2015-08-01

    The purpose of this study was to estimate the prevalence of reported near-miss wrong-patient events in radiology at two large academic hospitals and its relation to imaging modality, clinical setting, and time of occurrence. An institutional imaging report database was searched for reports between January 1, 2009, and May 30, 2013, that contained the phrases "incorrect patient" or "wrong patient." These imaging reports were categorized into either mislabeled or misidentified patient or wrong dictation or report events. The mislabeling-misidentification events involved patients whose images were incorrectly placed in another patient's folder. In wrong dictation or report events, a patient's images were placed in the correct imaging folder, but another patient's images were used in error for dictation of the report. The time to detect each of these events was also evaluated. Overall, 67 eligible reports were identified among 1,717,713 examinations performed during the study period. The estimated event rate was 4 per 100,000 examinations (mislabeling-misidentification, 52%; wrong dictation, 48%). The monthly mean of mislabeling-misidentification events was 0.7 (SD, 0.9) and of wrong dictation events was 0.6 (SD, 0.7). The median time for mislabeling-misidentification reports to be identified was 22 hours and for wrong dictation reports was 0 hours. Portable chest radiography was the modality involved in 69% (24/35) of reported mislabeling-misidentification and 44% (14/32) of wrong dictation events (p = 0.08); 43% (15/35) of mislabeling-misidentification and 28% (9/32) of wrong dictation events occurred during off hours; 63% (22/35) of mislabeling-misidentification and 56% (18/32) of wrong dictation events occurred in the inpatient setting. Despite use of the dual-identifier technique mandated by The Joint Commission, the number of near-miss mislabeled patient events for imaging tests and the delay in awareness of these events were substantial, especially for

Similar opposing judgments could be made for Cavi-Art which denotes a product made of sea kelp that imitates “real” caviar, or Pizzatop which denotes a product developed to be put on top of pizzas exactly like “real” cheese, but which does not qualify as cheese....... Starting from a review of 821 Danish regulatory cases concerning misleading food naming and labeling, we specifically address conflict scenarios that relate to the naming of innovative “sensory equivalents” to well-established food products. The arguments and assumptions put forward in real-life cases......-Ham, in that it would be tantamount to accepting that the “world has gone wrong” – so instead they maintain that the word is wrong.

    The use of radioactive isotopes for the study of sediment deposits is based mainly on two methods: marking in the mass - a glass of an element which can be activated replaces the sediment; surface marking - a physico-chemical process is used to deposit a radio-element at the surface of the sediment. The second process is used in particular for sands when it is advantageous to have a large number of particles for statistical analysis. The aim of this work was to develop a rapid and simple method of marking which could be applied on the actual site of the experiment where equipment, may be limited. The method recommended for marking sand with gold-198 is a combination of the Petersen (treatment with tin chloride) and Campbell (treatment with silver) methods combined with prior treatments with nitric acid and caustic soda. Using this method it is possible to deposit 125 mg of gold per kilo of sediment with a yield of 95 per cent (i.e. 10 Ci/kg) using a hydrochloric acid solution containing gold. The problem of the solidity of the deposits, of their value and of their reproducibility is discussed from the point of view of the mineral constitution of the sand. (author) [French] L'utilisation d'isotopes radioactifs pour l'etude des deplacements sedimentaires fait, principalement appel a deux methodes: le marquage massique - un verre contenant un element activable remplace le sediment; le marquage superficiel - un traitement physico-chimique permet de deposer un radioelement a la surface du sediment. Le second procede est surtout employe pour les sables lorsqu'il est utile de disposer d'un grand nombre de grains pour des raisons statistiques. Le but de ce travail etait de mettre au point une methode simple et rapide de marquage pouvant etre appliquee sur le site meme de l'experience pour les utilisateurs disposant d'un equipement limite.

    Product distribution theory is a new collective intelligence-based framework for analyzing and controlling distributed systems. Its usefulness in distributed stochastic optimization is illustrated here through an airline fleet assignment problem. This problem involves the allocation of aircraft to a set of flights legs in order to meet passenger demand, while satisfying a variety of linear and non-linear constraints. Over the course of the day, the routing of each aircraft is determined in order to minimize the number of required flights for a given fleet. The associated flow continuity and aircraft count constraints have led researchers to focus on obtaining quasi-optimal solutions, especially at larger scales. In this paper, the authors propose the application of this new stochastic optimization algorithm to a non-linear objective cold start fleet assignment problem. Results show that the optimizer can successfully solve such highly-constrained problems (130 variables, 184 constraints).

  13. Sex Work Criminalization Is Barking Up the Wrong Tree.

    2017-08-01

    There is a notable shift toward more repression and criminalization in sex work policies, in Europe and elsewhere. So-called neo-abolitionism reduces sex work to trafficking, with increased policing and persecution as a result. Punitive "demand reduction" strategies are progressively more popular. These developments call for a review of what we know about the effects of punishing and repressive regimes vis-à-vis sex work. From the evidence presented, sex work repression and criminalization are branded as "waterbed politics" that push and shove sex workers around with an overload of controls and regulations that in the end only make things worse. It is illustrated how criminalization and repression make it less likely that commercial sex is worker-controlled, non-abusive, and non-exploitative. Criminalization is seriously at odds with human rights and public health principles. It is concluded that sex work criminalization is barking up the wrong tree because it is fighting sex instead of crime and it is not offering any solution for the structural conditions that sex work (its ugly sides included) is rooted in. Sex work repression travels a dead-end street and holds no promises whatsoever for a better future. To fight poverty and gendered inequalities, the criminal justice system simply is not the right instrument. The reasons for the persistent stigma on sex work as well as for its present revival are considered.

  14. At least some errors are randomly generated (Freud was wrong)

    Sellen, A. J.; Senders, J. W.

    1986-01-01

    An experiment was carried out to expose something about human error generating mechanisms. In the context of the experiment, an error was made when a subject pressed the wrong key on a computer keyboard or pressed no key at all in the time allotted. These might be considered, respectively, errors of substitution and errors of omission. Each of seven subjects saw a sequence of three digital numbers, made an easily learned binary judgement about each, and was to press the appropriate one of two keys. Each session consisted of 1,000 presentations of randomly permuted, fixed numbers broken into 10 blocks of 100. One of two keys should have been pressed within one second of the onset of each stimulus. These data were subjected to statistical analyses in order to probe the nature of the error generating mechanisms. Goodness of fit tests for a Poisson distribution for the number of errors per 50 trial interval and for an exponential distribution of the length of the intervals between errors were carried out. There is evidence for an endogenous mechanism that may best be described as a random error generator. Furthermore, an item analysis of the number of errors produced per stimulus suggests the existence of a second mechanism operating on task driven factors producing exogenous errors. Some errors, at least, are the result of constant probability generating mechanisms with error rate idiosyncratically determined for each subject.

    To describe clinical effects, circumstances of occurrence, management and outcomes of cases of inadvertent administration of medications by an incorrect parenteral route. Retrospective single-center consecutive review of parenteral route errors of medications, reported to our center between January 2006 and June 2010. We collected demographic data and information on medications, route and time of administration, severity of symptoms/signs, treatment, and outcome. Seventy-eight cases (68 adults, 10 children) were available for analysis. The following wrong administration routes were recorded: paravenous (51%), intravenous (33%), subcutaneous (8%), and others (8%). Medications most frequently involved were iodinated x-ray contrast media (11%) and iron infusions (9%). Twenty-eight percent of the patients were asymptomatic and 54% showed mild symptoms; moderate and severe symptoms were observed in 9% and 7.7%, respectively, and were mostly due to intravenous administration errors. There was no fatal outcome. In most symptomatic cases local nonspecific treatment was performed. Enquiries concerning administration of medicines by an incorrect parenteral route were rare, and mainly involved iodinated x-ray contrast media and iron infusions. Most events occurred in adults and showed a benign clinical course. Although the majority of exposures concerned the paravenous route, the occasional severe cases were observed mainly after inadvertent intravenous administration.

    Full Text Available The wrongful conviction of innocent people is being acknowledged in an increasing number of countries around the world. The problem of wrongful conviction is now framed as an international human rights issue. More attention is being given to whether criminal justice systems are providing sufficient measures for the effective review and rectification of wrongful convictions and whether international obligations in that regard are being met. England, Wales, Northern Ireland, Scotland, Norway, Canada and the United States have substantial new mechanisms in place to better identify and correct wrongful convictions but Australia has been slower to respond. While some Australian states have introduced reforms such as DNA innocence testing and a new appeal avenue, many issues remain as highlighted in recent debates as to whether Australia should establish a Criminal Cases Review Commission.

    Specific clinical interventions are needed to reduce wrong-site surgery, which is a rare but potentially disastrous clinical error. Risk factors contributing to wrong-site surgery are variable and complex. The introduction of organisational and professional clinical strategies have a role in minimising wrong-site surgery. To evaluate the effectiveness of organisational and professional interventions for reducing wrong-site surgery (including wrong-side, wrong-procedure and wrong-patient surgery), including non-surgical invasive clinical procedures such as regional blocks, dermatological, obstetric and dental procedures and emergency surgical procedures not undertaken within the operating theatre. For this update, we searched the following electronic databases: the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register (January 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014), MEDLINE (June 2011 to January 2014), EMBASE (June 2011 to January 2014), CINAHL (June 2011 to January 2014), Dissertations and Theses (June 2011 to January 2014), African Index Medicus, Latin American and Caribbean Health Sciences database, Virtual Health Library, Pan American Health Organization Database and the World Health Organization Library Information System. Database searches were conducted in January 2014. We searched for randomised controlled trials (RCTs), non-randomised controlled trials, controlled before-after studies (CBAs) with at least two intervention and control sites, and interrupted-time-series (ITS) studies where the intervention time was clearly defined and there were at least three data points before and three after the intervention. We included two ITS studies that evaluated the effectiveness of organisational and professional interventions for reducing wrong-site surgery, including wrong-side and wrong-procedure surgery.

    Wrong-site surgery (WSS) is considered a sentinel event by the Joint Commission. The education of spine surgery fellows on WSS is unknown. Our objective was to evaluate North American spine surgery fellows' education, awareness, and experience with WSS. Observational survey study. Spine surgery fellows in North America. From April 2013 to July 2013 and in July 2014 anonymous questionnaires were sent to 156 spine surgery fellows participating in 75 programs. Demographic information (fellowship location and Accreditation Council for Graduate Medical Education accreditation of the fellowship) were collected. We also collected data on the following: if didactics on WSS are offered during fellowship, spine surgery fellows' experience with WSS, WSS prevention methods used during fellowship, and whether spine surgery fellows are interested in didactics or webinars on the prevention of WSS. Of 152 spine surgery fellows, 46 (30.3%) completed the questionnaires. Among them, 39 (84.6%) were orthopedic surgeons and 7 (15.4%) were neurosurgeons. Most were in non-Accreditation Council for Graduate Medical Education-accredited programs (70%) and were in training in the Midwest (37%), the South (30.4%), the Northeast (15.2%), and the West (15.2%). Furthermore, 30.4% had experienced WSS. Only 15 fellows (33%) had formal didactics on WSS during their fellowship. Most spine surgery fellows (61%, p = 0.03) were interested in a formal didactics on the prevention of WSS during their fellowship curriculum. Most (58.7%) were also interested in a Webinar on the prevention of WSS. We found of the 14 fellows that experienced WSS, 11 (79%) were significantly interested in formal didactics on WSS compared with those who had not experienced WSS (14/32, 44%; p didactics on WSS. Owing to the significant patient care and medicolegal ramifications from WSS, spine surgery fellowships should consider adding WSS prevention didactics to their curriculum.

    Au Quebec, les alumineries sont de grandes consommatrices d'energie electrique, soit pres de 14 % de la puissance installee d'Hydro-Quebec. Dans ce contexte, des petits gains en efficacite energetique des cuves d'electrolyse pourraient avoir un impact important sur la reduction globale de la consommation d'electricite. Le projet de maitrise decrit dans cette etude repond a la problematique suivante : comment l'optimisation de la geometrie d'un bloc cathodique en vue d'uniformiser la densite de courant peut augmenter l'efficacite energetique et la duree de vie de la cuve d'aluminium? Le but premier du projet est de modifier la geometrie en vue d'ameliorer le comportement thermoelectrique des blocs cathodiques et d'accroitre par le fait meme l'efficacite energetique du procede de production d'aluminium. La mauvaise distribution de la densite de courant dans la cuve est responsable de certains problemes energetiques ayant des impacts negatifs sur l'economie et l'environnement. Cette non-uniformite de la distribution du courant induit une usure prematuree de la surface de la cathode et contribue a reduire la stabilite magnetohydrodynamique de la nappe de metal liquide. Afin de quantifier les impacts que peut avoir l'uniformisation de la densite de courant a travers le bloc cathodique, un modele d'un bloc cathodique d'une cuve de la technologie AP-30 a ete concu et analyse par elements finis. A partir de son comportement thermoelectrique et de donnees experimentales d'une cuve AP-30 tirees de la litterature, une correlation entre le profil de densite de courant a la surface du bloc et le taux d'erosion local au meme endroit a ete creee. Cette relation correspond au modele predictif de la duree de vie de tout bloc du meme materiau a partir de son profil de densite de courant. Ensuite, une programmation a ete faite incorporant dans une meme fonction cout les impacts economiques de la duree de vie, de la chute de voltage cathodique et de l'utilisation de nouveaux materiaux

    2011-11-01

    The quadratic assignment problem, QAP, is one of the most difficult of all combinatorial optimization problems. Here, we use an abbreviated application of the statistical mechanics replica method to study the asymptotic behavior of instances in which the entries of at least one of the two matrices that specify the problem are chosen from a random distribution P. Surprisingly, the QAP has not been studied before using the replica method despite the fact that the QAP was first proposed over 50 years ago and the replica method was developed over 30 years ago. We find simple forms for C min and C max , the costs of the minimal and maximum solutions respectively. Notable features of our results are the symmetry of the results for C min and C max and their dependence on P only through its mean and standard deviation, independent of the details of P.

  4. Integrated assignment and path planning

    A surge of interest in unmanned systems has exposed many new and challenging research problems across many fields of engineering and mathematics. These systems have the potential of transforming our society by replacing dangerous and dirty jobs with networks of moving machines. This vision is fundamentally separate from the modern view of robotics in that sophisticated behavior is realizable not by increasing individual vehicle complexity, but instead through collaborative teaming that relies on collective perception, abstraction, decision making, and manipulation. Obvious examples where collective robotics will make an impact include planetary exploration, space structure assembly, remote and undersea mining, hazardous material handling and clean-up, and search and rescue. Nonetheless, the phenomenon driving this technology trend is the increasing reliance of the US military on unmanned vehicles, specifically, aircraft. Only a few years ago, following years of resistance to the use of unmanned systems, the military and civilian leadership in the United States reversed itself and have recently demonstrated surprisingly broad acceptance of increasingly pervasive use of unmanned platforms in defense surveillance, and even attack. However, as rapidly as unmanned systems have gained acceptance, the defense research community has discovered the technical pitfalls that lie ahead, especially for operating collective groups of unmanned platforms. A great deal of talent and energy has been devoted to solving these technical problems, which tend to fall into two categories: resource allocation of vehicles to objectives, and path planning of vehicle trajectories. An extensive amount of research has been conducted in each direction, yet, surprisingly, very little work has considered the integrated problem of assignment and path planning. This dissertation presents a framework for studying integrated assignment and path planning and then moves on to suggest an exact

    2015-03-01

    To respond to widespread disparities in access to oral health care, the Institute of Medicine, the Commission on Dental Accreditation (CODA), and the U.S. surgeon general have stressed that prospective dentists should become culturally competent, socially responsible practitioners. The aim of this study was to examine linguistic differences in dental students' reflective writing assignments before and after interviewing an individual who was culturally different from themselves. The authors analyzed 160 documents from 80 first-year dental students at the University of Florida in 2012. This cohort consisted of 36 male (45%) and 44 female (55%) students; 26 (32%) were from underrepresented minority (URM) groups and 54 (68%) were identified as white non-minority. Text analysis software identified word counts, categories, frequencies, and contexts. Significantly positive differences occurred for interviews between assignments 1 and 2 (p=0.005 to pFactor 1 ("important others' influence") between assignments (pFactor 4 ("my social world in relation to others") was statistically different between assignments for URM/majority participants (p=0.019). Factor 5 ("wrong because") was statistically different for gender (p=0.041), suggesting that males may have experienced a rebound effect from stereotype suppression. The findings suggest that the use of reflective writing and interviews affected the students' awareness of how important others had influenced their lives and attitudes and facilitated their questioning preconceived assumptions. Reactions to coursework focusing on social and personal domains warrant further investigation.

  11. Can Psychopathic Offenders Discern Moral Wrongs? A New Look at the Moral/Conventional Distinction

    Science.gov (United States)

    Sinnott-Armstrong, Walter; Kiehl, Kent A.

    2012-01-01

    A prominent view of psychopathic moral reasoning suggests that psychopathic individuals cannot properly distinguish between moral wrongs and other types of wrongs. The present study evaluated this view by examining the extent to which 109 incarcerated offenders with varying degrees of psychopathy could distinguish between moral and conventional transgressions relative to each other and to non-incarcerated healthy controls. Using a modified version of the classic Moral/Conventional Transgressions task (Nucci & Turiel, 1978) that employs a forced-choice format to minimize strategic responding, the present study found that total psychopathy score did not predict performance on the task. Task performance was explained by some individual sub-facets of psychopathy and by other variables unrelated to psychopathy, such as IQ. The authors conclude that, contrary to earlier claims, insufficient data exist to infer that psychopathic individuals cannot know what is morally wrong. PMID:21842959

    Full Text Available In analysing 'wrongful life' cases, comparative law is used extensively. This article examines these wrongful life cases, especially in light of the contradicting outcomes in different jurisdictions across the world, with the Dutch Kelly case and the South African decision in Stewart v Botha as its main examples. I will test the hypothesis that it is not so much the outcomes and (more importantly the arguments found elsewhere through the comparative law method that are decisive in highly debated cases like those concerning wrongful life, but that instead it is something else that decides the issue, something I would define as the cultural background of, or the legal policies within a tort law system.

    Homework has been cited as an integral part of a number of theoretical orientations and therapy formats; unfortunately, very little has been written about its use with couples and families. This is despite the fact that many couple and family therapists espouse the use of homework or out-of-session assignments in order to help the effects of therapy jell. This article reviews some of the empirical literature on homework assignments and their effectiveness in the domain of therapy for families and couples. It also highlights the effectiveness of and the need for out-of-session assignments in treatment. A case illustration is used to demonstrate how homework assignments may be used as a significant change agent in couple and family treatment. Copyright 2002 Wiley Periodicals, Inc.

  14. Competitive Traffic Assignment in Road Networks

    Directory of Open Access Journals (Sweden)

    Krylatov Alexander Y.

    2016-09-01

    Full Text Available Recently in-vehicle route guidance and information systems are rapidly developing. Such systems are expected to reduce congestion in an urban traffic area. This social benefit is believed to be reached by imposing the route choices on the network users that lead to the system optimum traffic assignment. However, guidance service could be offered by different competitive business companies. Then route choices of different mutually independent groups of users may reject traffic assignment from the system optimum state. In this paper, a game theoretic approach is shown to be very efficient to formalize competitive traffic assignment problem with various groups of users in the form of non-cooperative network game with the Nash equilibrium search. The relationships between the Wardrop’s system optimum associated with the traffic assignment problem and the Nash equilibrium associated with the competitive traffic assignment problem are investigated. Moreover, some related aspects of the Nash equilibrium and the Wardrop’s user equilibrium assignments are also discussed.

  16. Flexible taxonomic assignment of ambiguous sequencing reads

    Directory of Open Access Journals (Sweden)

    Jansson Jesper

    2011-01-01

    Full Text Available Abstract Background To characterize the diversity of bacterial populations in metagenomic studies, sequencing reads need to be accurately assigned to taxonomic units in a given reference taxonomy. Reads that cannot be reliably assigned to a unique leaf in the taxonomy (ambiguous reads are typically assigned to the lowest common ancestor of the set of species that match it. This introduces a potentially severe error in the estimation of bacteria present in the sample due to false positives, since all species in the subtree rooted at the ancestor are implicitly assigned to the read even though many of them may not match it. Results We present a method that maps each read to a node in the taxonomy that minimizes a penalty score while balancing the relevance of precision and recall in the assignment through a parameter q. This mapping can be obtained in time linear in the number of matching sequences, because LCA queries to the reference taxonomy take constant time. When applied to six different metagenomic datasets, our algorithm produces different taxonomic distributions depending on whether coverage or precision is maximized. Including information on the quality of the reads reduces the number of unassigned reads but increases the number of ambiguous reads, stressing the relevance of our method. Finally, two measures of performance are described and results with a set of artificially generated datasets are discussed. Conclusions The assignment strategy of sequencing reads introduced in this paper is a versatile and a quick method to study bacterial communities. The bacterial composition of the analyzed samples can vary significantly depending on how ambiguous reads are assigned depending on the value of the q parameter. Validation of our results in an artificial dataset confirm that a combination of values of q produces the most accurate results.

    2014-12-01

    Full Text Available In this study, we examine the wrong forms of some Yorùbá sentences that have become personal names through compounding. The data were extracted from the Joint Admissions and Matriculation Board (JAMB lists of candidates that were considered for admission into three Nigerian Universities between the 2005 and 2010 academic sessions. The names extracted from that source were compared with names written in the staff lists of the three Universities in Nigeria. The wrongly written names were recorded on tapes and some native speakers were asked to listen to them to determine their correctness. We argue that wrong forms of some Yorùbá sentential/personal names are common occurrences and establish that they are traceable to the freedom granted by Yorùbá orthography developers. We also argue that, the confusion that results from the different spelling forms of some Yorùbá personal names is seriously observable in social interactions, labour market, schools or Colleges of Education/Universities, Embassies and Nigerian civil service both Federal and State and that court affidavits become imperative to authenticate or reconcile both the wrong and the correct forms for the purposes of admissions, appointments and overseas travelling documents. Similarly, we show that the position of the Yorùbá orthography developers has resulted in a loss of the actual pronunciation of some Yorùbá personal names which has severe implications for the semantic contents of the names as well as implications for the rich religious, cultural and philosophical heritage of the Yorùbá people.

    Phillips, Mark; Dove, Edward S; Knoppers, Bartha M

    2017-12-01

    The collapse of confidence in anonymization (sometimes also known as de-identification) as a robust approach for preserving the privacy of personal data has incited an outpouring of new approaches that aim to fill the resulting trifecta of technical, organizational, and regulatory privacy gaps left in its wake. In the latter category, and in large part due to the growth of Big Data-driven biomedical research, falls a growing chorus of calls for criminal and penal offences to sanction wrongful re-identification of "anonymized" data. This chorus cuts across the fault lines of polarized privacy law scholarship that at times seems to advocate privacy protection at the expense of Big Data research or vice versa. Focusing on Big Data in the context of biomedicine, this article surveys the approaches that criminal or penal law might take toward wrongful re-identification of health data. It contextualizes the strategies within their respective legal regimes as well as in relation to emerging privacy debates focusing on personal data use and data linkage and assesses the relative merit of criminalization. We conclude that this approach suffers from several flaws and that alternative social and legal strategies to deter wrongful re-identification may be preferable.

  1. Protein secondary structure assignment revisited: a detailed analysis of different assignment methods

    Directory of Open Access Journals (Sweden)

    de Brevern Alexandre G

    2005-09-01

    Full Text Available Abstract Background A number of methods are now available to perform automatic assignment of periodic secondary structures from atomic coordinates, based on different characteristics of the secondary structures. In general these methods exhibit a broad consensus as to the location of most helix and strand core segments in protein structures. However the termini of the segments are often ill-defined and it is difficult to decide unambiguously which residues at the edge of the segments have to be included. In addition, there is a "twilight zone" where secondary structure segments depart significantly from the idealized models of Pauling and Corey. For these segments, one has to decide whether the observed structural variations are merely distorsions or whether they constitute a break in the secondary structure. Methods To address these problems, we have developed a method for secondary structure assignment, called KAKSI. Assignments made by KAKSI are compared with assignments given by DSSP, STRIDE, XTLSSTR, PSEA and SECSTR, as well as secondary structures found in PDB files, on 4 datasets (X-ray structures with different resolution range, NMR structures. Results A detailed comparison of KAKSI assignments with those of STRIDE and PSEA reveals that KAKSI assigns slightly longer helices and strands than STRIDE in case of one-to-one correspondence between the segments. However, KAKSI tends also to favor the assignment of several short helices when STRIDE and PSEA assign longer, kinked, helices. Helices assigned by KAKSI have geometrical characteristics close to those described in the PDB. They are more linear than helices assigned by other methods. The same tendency to split long segments is observed for strands, although less systematically. We present a number of cases of secondary structure assignments that illustrate this behavior. Conclusion Our method provides valuable assignments which favor the regularity of secondary structure segments.

    CERN Document Server

    Duque, Daniel

    2016-01-01

    In Computational Fluid Dynamics there have been many attempts to combine the power of a fixed mesh on which to carry out spatial calculations with that of a set of particles that moves following the velocity field. These ideas indeed go back to Particle-in-Cell methods, proposed about 60 years ago. Of course, some procedure is needed to transfer field information between particles and mesh. There are many possible choices for this "assignment", or "projection". Several requirements may guide this choice. Two well-known ones are conservativity and stability, which apply to volume integrals of the fields. An additional one is here considered: preservation of information. This means that mesh interpolation, followed by mesh assignment, should leave the field values invariant. The resulting methods are termed "mass" assignments due to their strong similarities with the Finite Element Method. We test several procedures, including the well-known FLIP, on three scenarios: simple 1D convection, 2D convection of Zales...

    Beal, Nathan J; O'Malley, Patrick J

    2016-04-06

    The oxidation state assignment of the manganese ions present in the superoxidized manganese (III/IV) catalase active site is determined by comparing experimental and broken symmetry density functional theory calculated (14)N, (17)O, and (1)H hyperfine couplings. Experimental results have been interpreted to indicate that the substrate water is coordinated to the Mn(III) ion. However, by calculating hyperfine couplings for both scenarios we show that water is coordinated to the Mn(IV) ion and that the assigned oxidation states of the two manganese ions present in the site are the opposite of that previously proposed based on experimental measurements alone.

    This paper reports the performance of particle swarm optimization (PSO) for the assignment of blood to meet patients' blood transfusion requests for blood transfusion. While the drive for blood donation lingers, there is need for effective and efficient management of available blood in blood banking systems. Moreover, inherent danger of transfusing wrong blood types to patients, unnecessary importation of blood units from external sources, and wastage of blood products due to nonusage necessitate the development of mathematical models and techniques for effective handling of blood distribution among available blood types in order to minimize wastages and importation from external sources. This gives rise to the blood assignment problem (BAP) introduced recently in literature. We propose a queue and multiple knapsack models with PSO-based solution to address this challenge. Simulation is based on sets of randomly generated data that mimic real-world population distribution of blood types. Results obtained show the efficiency of the proposed algorithm for BAP with no blood units wasted and very low importation, where necessary, from outside the blood bank. The result therefore can serve as a benchmark and basis for decision support tools for real-life deployment.

    Dam, Gregory; Kording, Konrad; Wei, Kunlin

    2013-01-01

    We often need to learn how to move based on a single performance measure that reflects the overall success of our movements. However, movements have many properties, such as their trajectories, speeds and timing of end-points, thus the brain needs to decide which properties of movements should be improved; it needs to solve the credit assignment problem. Currently, little is known about how humans solve credit assignment problems in the context of reinforcement learning. Here we tested how human participants solve such problems during a trajectory-learning task. Without an explicitly-defined target movement, participants made hand reaches and received monetary rewards as feedback on a trial-by-trial basis. The curvature and direction of the attempted reach trajectories determined the monetary rewards received in a manner that can be manipulated experimentally. Based on the history of action-reward pairs, participants quickly solved the credit assignment problem and learned the implicit payoff function. A Bayesian credit-assignment model with built-in forgetting accurately predicts their trial-by-trial learning.

  12. Court decisions in wrongful birth cases as possible discrimination against the child

    Directory of Open Access Journals (Sweden)

    Petr Sustek

    2017-04-01

    Full Text Available Abstract: The term wrongful birth denotes a claim brought by the parents of an unwanted child who was conceived or born due to medical negligence. The claims are often dismissed as contradictory to good morals or public order. However, there remains a neglected question whether the court decision to award or dismiss damages could constitute discrimination against the child concerned. While the child is not a party to the litigation, it is nevertheless unacceptable for the court not to take into account the effects of its decision on the child. In the case of award of damages, the court publicly affirms the legitimacy of the parentsꞌ need for compensation, that is the fact that the childꞌs birth represents recoverable harm to them. The court decision therefore means a different treatment in respect to other children whose benefits for the family are generally recognized and praised by the society. That might have serious psychological consequences for the child, depriving her or him of the full enjoyment of the right to dignity. This fact constitutes discrimination on the grounds of birth, which can be justified only by very weighty reasons. Such reasons may be arguably given in the case of a child incapable of understanding the meaning of wrongful birth litigation, whose special needs are extremely burdensome on the family. On the other hand, the dismissal of the claim cannot represent a negative discrimination against the child. Keywords: Discrimination. Wrongful birth. International human rights law. Human rights of the child. Convention on the Rights of the Child.

    Hunt, Carl E; Darnall, Robert A; McEntire, Betty L; Hyma, Bruce A

    2015-06-01

    We have reached a conundrum in assigning cause of death for sudden unexpected infant deaths. We summarize the discordant perspectives and approaches and how they have occurred, and recommend a pathway toward improved consistency. This lack of consistency affects pediatricians and other health care professionals, scientific investigators, medical examiners and coroners, law enforcement agencies, families, and support or advocacy groups. We recommend that an interdisciplinary international committee be organized to review current approaches for assigning cause of death, and to identify a consensus strategy for improving consistency. This effort will need to encompass intrinsic risk factors or infant vulnerability in addition to known environmental risk factors including unsafe sleep settings, and must be sufficiently flexible to accommodate a progressively expanding knowledge base.

    2018-01-01

    Quadratic Assignment Problem (QAP) has been a very popular problem to be solved among researchers due to its practical applications. Several variants of QAP have been proposed by researchers in the past in order to reflect the real situations of QAP. One of the real problems of QAP is related with facilities which are required to be assigned to certain locations due to its function. In solving this problem, a fixed assignment has to be made thus allowing for the complexity of the problem to be reduced. Hence, this study introduces Quadratic Assignment Problem with Fixed Assignment (QAPFA) with the objective to minimize the assignment cost between the facility and location. This assignment takes into account the flow and distance between facility and location. QAPFA represents the real-world situation of the problem especially in dealing with specific requirement of some facilities to specific locations. Dataset of QAPFA is introduced and is solved using branch and bound approach. As for validation, the results of QAPFA are compared with QAP in terms of objective function and running time. The computational results show that the solution quality of QAPFA is lower when compared with the QAP, while the running time for QAPFA is lower than the QAP. Since the complexity of the problem is reduced by fixing the assignment, thus there is possibility that QAPFA has lower quality than QAP due to the fixed assignment. Nevertheless, in terms of running time QAPFA is better than QAP. It can be concluded that this problem reflect the real problem and practical to be used.

  16. Gender Assignment in Danish, Swedish and Norwegian: A Comparison of the Status of Assignment Criteria

    Directory of Open Access Journals (Sweden)

    Marcin Kilarski

    2004-01-01

    Full Text Available The paper deals with gender assignment of English loanwords in Danish, Swedish and Norwegian. The following assignment criteria have been analysed: semantic (animate, mass, phonological (number of syllables, homonymy, and morphological (inflection, suffixation, deverbal monosyllables, compounds. Common gender in Danish and Swedish and masculine in Norwegian are overrepresented in comparison with the native lexicon. This is confirmed by discriminant function analysis, which shows that neuter nouns in the three languages and feminine nouns in Norwegian show fewer characteristic features. This analysis has also been used to measure the degree of regularity based on the postulated criteria: the percentage of correctly classified cases (from 67% in Swedish to 68% in Norwegian and 72% in Danish suggests only a partial regularity in gender assignment. The stronger pull of common or masculine gender is reflected in the contribution of selected assignment rules, particularly in the assignment of animates, where common or masculine nouns constitute 96% of assigned nouns. As regards phonological rules, monosyllables show a slightly better correlation with neuter gender, particularly in Danish. Homonymy is significant for nouns of both genders in Danish, while in Swedish and Norwegian nouns with a native neuter or feminine homonym are more likely to be assigned common or masculine gender. Likewise, most inflectional and derivational assignment rules contribute to the assignment of common or masculine genders, with the exception of zero plurals, Swedish n-plurals, suffixes such as -ment, -ery, deverbal monosyllables in Danish and Norwegian, and compounds whose base appears in the corpus with n. gender. Discriminant function analysis shows that plural inflection has the greatest discriminant power among the postulated criteria. Finally, it is suggested that these tendencies may indicate an ongoing expansion of common and masculine genders in the three

    2017-01-01

    The optimum time students should spend on homework has been widely researched although the results are far from unanimous. The main objective of this research is to analyze how homework assignment strategies in schools affect students' academic performance and the differences in students' time spent on homework. Participants were a representative sample of Spanish adolescents (N = 26,543) with a mean age of 14.4 (±0.75), 49.7% girls. A test battery was used to measure academic performance in four subjects: Spanish, Mathematics, Science, and Citizenship. A questionnaire allowed the measurement of the indicators used for the description of homework and control variables. Two three-level hierarchical-linear models (student, school, autonomous community) were produced for each subject being evaluated. The relationship between academic results and homework time is negative at the individual level but positive at school level. An increase in the amount of homework a school assigns is associated with an increase in the differences in student time spent on homework. An optimum amount of homework is proposed which schools should assign to maximize gains in achievement for students overall.

  1. When patients are harmed, but are not wronged: ethics, law, and history.

    Iatrogenic injury-injury caused unintentionally by medical treatment-breaks the oldest and most famous rule of medical ethics: primum non nocere, or above all, do no harm. Medical malpractice law, however, focuses on whether an injury was caused by negligence, not on whether an injury was iatrogenic. Iatrogenic injury inflicted without negligence is a common pattern in medical malpractice lawsuits; it is likely the pattern of Jacobs v Cross (Minnesota, 1872), in which Dr W. W. Mayo testified as an expert witness. As a matter of law, the doctor defendants should win all those lawsuits, for iatrogenic injury inflicted without negligence is not a legal wrong in the United States and has not been considered a legal wrong for hundreds of years. However, the medical ethics applicable to doctors' duties to report incompetence in colleagues, including those who inflict excessive iatrogenic injury, have developed dramatically over time. In 1872, the ethical codes in the United States exhorted doctors not to criticize another doctor, even if incompetent. Today, doctors in the United States are ethically required to report an incompetent colleague. Copyright © 2014 Mayo Foundation for Medical Education and Research. Published by Elsevier Inc.

  2. Wrongful birth and the politics of reproduction: West German and English law considered.

    Science.gov (United States)

    Shaw, J

    1990-01-01

    This article considers the law relating to compensation in tort and contract for failed sterilizations and failed abortions leading to the birth of an unplanned but healthy child in the Federal Republic of Germany and England. It uses a policy-based analysis which takes the social construction of gender as a significant factor in judicial decision making. It criticizes existing literature for failing to take into account gender divisions in society and points to ways in which both the framework within which wrongful birth cases are discussed generally and the limitations which have been placed on recovery specifically reflect gender stereotyped notions of female and male behaviour and sexuality. I conclude that there are three main areas of concern in the wrongful birth cases: a) the inadequate recognition which the law accords to women's work in the home when awarding damages for maintenance of the unplanned child to majority; b) the awarding damages exercised by the politics of abortion, which can lead to undue restrictions on recovery; and c) the difficulties which the law experiences when attempting to conceptualize an interference in a woman's procreative autonomy in the same terms as an interference in a typically 'male' sphere of life, such as professional autonomy. Thus there is an urgent need to reconsider the categories of the law of obligations such as 'damage' and 'compensation', which are central to the principle of individual responsibility for harm caused, in order to reveal their gendered content and differential effects.

  3. Eager feelings and vigilant reasons: Regulatory focus differences in judging moral wrongs

    Science.gov (United States)

    Cornwell, James F. M.; Higgins, E. Tory

    2015-01-01

    For over a decade, moral psychologists have been actively researching the processes underlying moral judgments that are made intuitively without reference to an action’s concrete harms or injustice, such as the well-known case of non-procreative, consensual incest. We suggest that the reason some judge this scenario as wrong (using intuitive feelings) and others do not (using deliberative reasons) is due to an important motivational distinction. Consistent with this view, across seven studies, we demonstrate that negative judgments of such intuitive moral scenarios are more intense when processed in the promotion focus compared to the prevention focus, and that this is due to differences in whether eager (intuitive) versus vigilant (deliberative) means are employed in judging these moral wrongs. By examining various boundary conditions for this phenomenon and foundations for these judgments, we learn about the overall differences between promotion and prevention regarding how proscriptive judgments are processed, and begin to integrate these differences with existing theories in moral psychology.

    Cohen, Fred L; Mendelsohn, Daniel; Bernstein, Mark

    2010-09-01

    The purpose of this case review was to identify and analyze existing wrong-site craniotomy (WSC) cases to determine the factors that contributed to the errors and to suggest preventative strategies for WSC. Wrong-site surgery (WSS) is a devastating surgical error that has gained increased public attention in recent years due to some high-profile cases. Despite the implementation of preventative methods such as preoperative checklists and surgical time-outs, WSS still occurs to this day. The clinical consequences of WSC are distinct compared with other types of WSS due to the unique function of the brain. The authors searched medical, legal, and media databases and contacted state medical licensing boards to identify and gather information about WSC cases. The cases were reviewed and analyzed for factors that contributed to the errors. Four major categories of contributing factors were found: 1) communication breakdown; 2) inadequate preoperative checks; 3) technical factors and imaging; and 4) human error. The WSC cases are used to illustrate how these types of factors can precipitate the surgical error. Clinical outcomes and disciplinary actions are summarized. Obtaining information about the cases discovered was very challenging, in part because WSS reporting is inadequate. This case review demonstrates that a broad range of events and factors can cause human errors to breach patient safeguards and lead to a WSC; however, in essentially all cases the WSCs were preventable with strict adherence to comprehensive and thorough protocols.

  5. Wrong and missing sire information affects genetic gain in the Angeln dairy cattle population.

    Sanders, K; Bennewitz, J; Kalm, E

    2006-01-01

    In the present study, molecular genetic markers were used to help estimate the degree of wrong sire information in the German Angeln dairy cattle population. Sixteen polymorphic microsatellite markers were genotyped on 5 different paternal half-sib families with a total of 805 daughters. For the genotyping process, blood samples of the daughters and semen samples of the sires were used. Allelic frequencies and exclusion probabilities were estimated. The simultaneous effect of wrong (WSI) and missing sire information (MSI) on the reliability of estimated breeding values and on the genetic gain was investigated using deterministic simulations. For these simulations, different values for the number of daughters per sire, heritability, WSI, and MSI were chosen. The estimated proportion of the WSI was 7% in the German Angeln dairy cattle population. The combined impact of WSI and MSI on the genetic gain was relatively large, especially in the case of small progeny size per sire and low heritability. The impact of WSI was more harmful than MSI on response to selection.

  6. The Reputational Consequences of Failed Replications and Wrongness Admission among Scientists.

    Directory of Open Access Journals (Sweden)

    Adam K Fetterman

    Full Text Available Scientists are dedicating more attention to replication efforts. While the scientific utility of replications is unquestionable, the impact of failed replication efforts and the discussions surrounding them deserve more attention. Specifically, the debates about failed replications on social media have led to worry, in some scientists, regarding reputation. In order to gain data-informed insights into these issues, we collected data from 281 published scientists. We assessed whether scientists overestimate the negative reputational effects of a failed replication in a scenario-based study. Second, we assessed the reputational consequences of admitting wrongness (versus not as an original scientist of an effect that has failed to replicate. Our data suggests that scientists overestimate the negative reputational impact of a hypothetical failed replication effort. We also show that admitting wrongness about a non-replicated finding is less harmful to one's reputation than not admitting. Finally, we discovered a hint of evidence that feelings about the replication movement can be affected by whether replication efforts are aimed one's own work versus the work of another. Given these findings, we then present potential ways forward in these discussions.

  7. A just alternative. Church tribunals may be the best forum for settling wrongful discharge disputes.

    Science.gov (United States)

    Fitzgerald, J M; Fitzgerald, L M

    1991-09-01

    The threat of a wrongful discharge lawsuit should be a concern for every employer. However, Church employers can minimize their risk if they follow Church teaching in their employment practices and policies and if they use the Church tribunal system to settle employer-employee disputes. As it originally developed in common law, the "employment-at-will" concept stipulated that an employer could discharge an employee at any time, for any reason, or for no reason at all. Most states have adopted this common law concept, although courts and legislatures have created a number of exceptions to it. Despite these exceptions, employment-at-will has proven to be a powerful tool in the hands of employers. However, employees of Church institutions who feel they have been discharged wrongfully can turn to Church tribunals, which are governed by canon law. A Church tribunal can do virtually anything a civil court can do, with the exception of ordering someone to jail. Moreover, because the standards of justice and equity applied by Church tribunals are stricter than those applied by American courts, employees of Catholic institutions in the United States may make increasing use of them in the future. Disputes that come before a Church tribunal will be settled by either arbitration or mediation. Arbitration is a kind of informal litigation. Mediation, however, is preferable because it forces the parties involved to examine themselves, their motives, and their effects on each other and the Church as a whole.

    In this paper the characteristic ratios and generalized time constant are defined for all-pole commensurate fractional order systems. The sufficient condition for stability of these systems in terms of their characteristic ratios is obtained. Also an analytical approach for characteristic ratio assignment (CRA) to have a non-overshooting fast closed loop step response is introduced. The proposed CRA method is then employed to design a fractional order controller. Computer simulation results are presented to illustrate the performance of the CRA based designed fractional order controllers. Copyright © 2010 ISA. Published by Elsevier Ltd. All rights reserved.

  11. The horror of wrong-site surgery continues: report of two cases in a regional trauma centre in Nigeria.

    Nwosu, Arinze

    2015-01-01

    Wrong- site surgeries are iatrogenic errors encountered in the course of surgical patient management. Despite the 'never do harm' pledge in the 'Hippocratic Oath' drafted in 5(th) century BC, man is after all human, with this limitation manifesting in the physician's art despite his best intention. Beyond the catastrophic consequences of wrong- site surgery on the patient and surgeon, and the opprobrium on the art of medicine, the incidents have come to be regarded as a quality-of-care indicator. Orthopaedic surgery is a specialty with a preponderance of this phenomenon and the attendant medico-legal issues relating to malpractice claims. Consequently the specialty had pioneered institutional initiatives at preventing these 'friendly-fires'. Awareness and implementation of these initiatives however remain low in many parts of the world, hampered by a culture of denial and shame. This report presents two cases of wrong-site surgery following trauma from road-traffic accident. The first case was a closed reduction of the 'wrong' dislocated hip in the trauma/emergency unit under the care of senior residents, while the second case was attempted wrong-site surgery on the right leg in a patient with fracture of the left tibia, in conjunction with bilateral femoral fracture and right radio-ulnar fracture; by an experienced Chief Consultant Orthopaedic Surgeon operating elective list. Both are orthopaedic cases, each with some trauma to both lower extremeties. Neither of the cases was formally mentioned anywhere in clinical discourse in the hospital, much less a formal report or audit. There was no formal, institutionalized process to prevent wrong-site surgery in the health institution and this could have been largely responsible for these incidents. An open, mandatory process of reporting such incidents for relevant audit and awareness is necessary, as a mechanism for prevention rather than blame or punishment.

  12. Optimization of demand assigned SCPC satellite networks

    Laborde, E.

    1985-09-01

    This paper investigates various system aspects and price tradeoffs involved in providing cost-effective Demand Assignment (DA) satellite channel service. Those network characteristics which significantly affect the ultimate cost-based decision are discussed. The number of stations participating in the DA or PA system, the number of satellite channels, and the traffic are kept parametric within expected limits, covering most of the present and future applications. In particular, the interrelationships between the network requirements (e.g., grade of service) and network elements, and the impacts of different blocking assignment allocations on the number of modems in the network is examined. A cost model is then derived that allows the evaluation and comparison of both DA and PA networks. Absolute and differential costing of PA and DA networks is permitted using economic quantities available to the system planner. These include modem cost, satellite channel cost, network size, and defined efficiency factors. Based on the differential cost comparisons for several DA and PA network strategies, tradeoffs have been derived to aid the system designer in configuring the most cost-effective DA network.

    2017-10-04

    Wrong-site/side surgical "never events" continue to cause considerable harm to patients, healthcare professionals, and organizations within the United Kingdom. Incidence has remained static despite the mandatory introduction of surgical checklists. Operating theater list errors have been identified as a regular contributor to these never events. The aims of the study were to identify and to learn from the incidence of wrong-site/side list errors in a single National Health Service board. The study was conducted in a single National Health Service board serving a population of approximately 300,000. All theater teams systematically recorded errors identified at the morning theater brief or checklist pause as part of a board-wide quality improvement project. Data were reviewed for a 2-year period from May 2013 to April 2015, and all episodes of wrong-site/side list errors were identified for analysis. No episodes of wrong-site/side surgery were recorded for the study period. A total of 86 wrong-site/side list errors were identified in 29,480 cases (0.29%). There was considerable variation in incidence between surgical specialties with ophthalmology recording the largest proportion of errors per number of surgical cases performed (1 in 87 cases) and gynecology recording the smallest proportion (1 in 2671 cases). The commonest errors to occur were "wrong-side" list errors (62/86, 72.1%). This is the first study to identify incidence of wrong-site/site list errors in the United Kingdom. Reducing list errors should form part of a wider risk reduction strategy to reduce wrong-site/side never events. Human factors barrier management analysis may help identify the most effective checks and controls to reduce list errors incidence, whereas resilience engineering approaches should help develop understanding of how to best capture and neutralize errors.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives

    The hydrophobicity of most amino acids correlates well with that of their anticodon nucleotides, with Trp, Tyr, Ile, and Ser being the exceptions to this rule. Using previous data on hydrophobicity and binding constants, and new data on rates of esterification of polyadenylic acid with several N-acetylaminoacyl imidazolides, several of the anticodon assignments are rationalized. Chemical reasons are shown supporting the idea of the inclusion of the Ile in the catalog of biological amino acids late in the evolution, through a mutation of the existing tRNA and its aminoacyl-tRNA-synthetase. It was found that an addition of hexane increases the incorporation of hydrophobic Ac-Phe into poly-A, in support of the Fox (1965) and Oparin (1965) emphasis on the biogenetic importance of phase-separated systems.

  15. INDEXING WORKSHOP: HOW TO ASSIGN KEYWORDS

    1979-09-01

    You have heard about issues surrounding indexing and retrieval of nuclear records and automation and micrographics of these records. Now we are going to get each of you involved in indexing and assigning keywords. The first part of this hands-on workshop will be a very basic, elementary step-by-step introduction, concentrating on how to assign keywords. It is a workshop for beginners, People who have never done it before. It is planned to demonstrate what an analyst has to do to index and assign keywords to a document. Then I will take some pages of a report and demonstrate how I choose keywords for it. Then each of you will have a chance to do the same thing with similar pages from another report. Then we will discuss the variations ln the keywords you individually assigned. There are many systems that can be used. In this particular workshop we will cover only a system of building your own keyword listing as you index your documents. We will be discussing keywords or descriptors or subject words, but first I want to point out a few other critical points about indexing. When developing an indexing project the most important thing to do first lS decide what elements you want to retrieve by. Whether you go into a large computer retrieval system or a small three-by-five card system, you have to decide in advance what you want to retrieve. Then you can go on from there. If you only need to search by equipment number or by purchase order or by contract number, then you can use a very simple retrieval system. But if you want to be able to retrieve a record by any combination of elements, then you have to consistently input these into your system. For example, if you want to be able to ask for the drawings of the piping in the secondary cooling system, level 3, manufactured by a certain vendor, then you must have put the information into the index by a retrieval file point, in advance. I want to stress that the time spent in deciding what has to be retrievable is never

    The volume of healthcare data is growing rapidly with the adoption of health information technology. We focus on automated ICD9 code assignment from discharge summary content and methods for evaluating such assignments. We study ICD9 diagnosis codes and discharge summaries from the publicly available Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC II) repository. We experiment with two coding approaches: one that treats each ICD9 code independently of each other (flat classifier), and one that leverages the hierarchical nature of ICD9 codes into its modeling (hierarchy-based classifier). We propose novel evaluation metrics, which reflect the distances among gold-standard and predicted codes and their locations in the ICD9 tree. Experimental setup, code for modeling, and evaluation scripts are made available to the research community. The hierarchy-based classifier outperforms the flat classifier with F-measures of 39.5% and 27.6%, respectively, when trained on 20,533 documents and tested on 2282 documents. While recall is improved at the expense of precision, our novel evaluation metrics show a more refined assessment: for instance, the hierarchy-based classifier identifies the correct sub-tree of gold-standard codes more often than the flat classifier. Error analysis reveals that gold-standard codes are not perfect, and as such the recall and precision are likely underestimated. Hierarchy-based classification yields better ICD9 coding than flat classification for MIMIC patients. Automated ICD9 coding is an example of a task for which data and tools can be shared and for which the research community can work together to build on shared models and advance the state of the art.

  17. Solving multiconstraint assignment problems using learning automata.

    This paper considers the NP-hard problem of object assignment with respect to multiple constraints: assigning a set of elements (or objects) into mutually exclusive classes (or groups), where the elements which are "similar" to each other are hopefully located in the same class. The literature reports solutions in which the similarity constraint consists of a single index that is inappropriate for the type of multiconstraint problems considered here and where the constraints could simultaneously be contradictory. This feature, where we permit possibly contradictory constraints, distinguishes this paper from the state of the art. Indeed, we are aware of no learning automata (or other heuristic) solutions which solve this problem in its most general setting. Such a scenario is illustrated with the static mapping problem, which consists of distributing the processes of a parallel application onto a set of computing nodes. This is a classical and yet very important problem within the areas of parallel computing, grid computing, and cloud computing. We have developed four learning-automata (LA)-based algorithms to solve this problem: First, a fixed-structure stochastic automata algorithm is presented, where the processes try to form pairs to go onto the same node. This algorithm solves the problem, although it requires some centralized coordination. As it is desirable to avoid centralized control, we subsequently present three different variable-structure stochastic automata (VSSA) algorithms, which have superior partitioning properties in certain settings, although they forfeit some of the scalability features of the fixed-structure algorithm. All three VSSA algorithms model the processes as automata having first the hosting nodes as possible actions; second, the processes as possible actions; and, third, attempting to estimate the process communication digraph prior to probabilistically mapping the processes. This paper, which, we believe, comprehensively reports the

  18. Elof Risebye – A Pioneer in the Transfer of Wall Paintings on the Wrong Path

    2001-01-01

    The transfer of wall paintings was introduced to Denmark by Italian restorers in 1913. A misunderstanding of this technique led to the development of a faulty method by Elof Risebye, an artist, who by chance got involved in the restoration of wall paintings. The use of the wrong adhesive resulted...... in massive damage of the paint layer. Risebye disguised his losses by overpainting, which he carried out according to his own style of painting, not at all following the style of the painter's whose work he was restoring. He also taught his students at the Fresco and Mosaic School how to detach frescoes......, thus disseminating his faulty method. Due to Risebye's activities there are a significant number of transferred wall paintings in Denmark which are in dire need of treatment today....

    Tiedown systems for truck transport of UF{sub 6} must be defined and controlled to assure the least risk for hauling the material over the highways. This paper and an associated poster display will present the current status of regulatory criteria for tiedowns, analyze the structural stresses involved in tiedowns for two major UF{sub 6} packaging systems, the 21PF series of overpacks and the 48 in. diameter shipping cylinders, and will present photographs showing some {open_quote}right ways{close_quotes} and some {open_quotes}wrong (or risky) ways{close_quotes} currently used for tiedown systems. Risky tiedown methods must be replaced with safer less risky methods to insure the safe transport of UF{sub 6}.

    Wrong patient selection errors are a major issue for patient safety; from ordering medication to performing surgery, the stakes are high. Widespread adoption of Electronic Health Record (EHR) and Computerized Provider Order Entry (CPOE) systems makes patient selection using a computer screen a frequent task for clinicians. Careful design of the user interface can help mitigate the problem by helping providers recall their patients' identities, accurately select their names, and spot errors before orders are submitted. We propose a catalog of twenty seven distinct user interface techniques, organized according to a task analysis. An associated video demonstrates eighteen of those techniques. EHR designers who consider a wider range of human-computer interaction techniques could reduce selection errors, but verification of efficacy is still needed.

    A measurement of the rate for the "wrong-sign" decay D0 -> K+ pi- pi+ pi- relative to that for the "right-sign" decay D0 -> K- pi+ pi+ pi- is presented. Using 791 fb-1 of data collected with the Belle detector, we obtain a branching fraction ratio of R_WS = [0.324 +- 0.008 (stat) +- 0.007 (sys)]%. Multiplying this ratio by the world average value for the branching fraction B(D0 -> K- pi+ pi+ pi-) gives a branching fraction B(D0 -> K+ pi- pi+ pi-) = (2.61 +- 0.06 +0.09 -0.08) x 10-4.

  2. Moral pluralism versus the total view: why Singer is wrong about radical life extension.

    Science.gov (United States)

    Blackford, R

    2009-12-01

    Peter Singer has argued that we should not proceed with a hypothetical life-extension drug, based on a scenario in which developing the drug would fail to achieve the greatest sum of happiness over time. However, this is the wrong test. If we ask, more simply, which policy would be more benevolent, we reach a different conclusion from Singer's: even given his (admittedly questionable) scenario, development of the drug should go ahead. Singer's rigorous utilitarian position pushes him in the direction of an implausible "total view" utilitarianism when it encounters the problems presented by certain thought experiments. A more pluralistic account of the nature of morality promises to solve these problems, and in this case it reaches a benevolent recommendation on life-extension technology.

  3. ECONOMICAL CRISIS IN ROMANIA – A CONSEQUENCE OF THE WRONG MIX OF MACRO-ECONOMICAL POLICIES

    Directory of Open Access Journals (Sweden)

    Lorena DUDUIALĂ POPESCU

    2010-09-01

    Full Text Available The economical crisis Romania starts to cross is mainly an internal crisis determined by the wrong mix of macro-economical policies established in the last years. Economic growth proves to be unhealthy; that is because we have had a growth based on consumption financed on debt during these years. Private consumption was excessive, but the population should not be blamed: all the macro-economical measures have been pro-cyclic, stimulating consumption; and the most damaging of the all, the unique rate, is still protected by its initiators who do not want to admit they were wrong. The unique rate has stimulated the consumption and we have nowadays the first crisis of overconsumption in Romania. The main cause is the excessive consumption on debt. The population cannot be blamed, but in the future it can be better informed and surely more precautious regarding the expectations for the own incomes. In exchange, the government may be criticized because it made a monumental strategic mistake: in a time of economical increase, it consumed all this increase and it indebted itself additionally. The budgetary deficit increased from 1,3% of PIB in 2008 to 2,6% last year and probably over 3% this year. Since the government has got to borrow hundreds of million euro with the date of payment of one week, the only logical conclusion is that there are no money for the current expenditures or for the ones already budgeted on the current year. It is absolutely inacceptable in a time of high economical increase for the budgetary deficit to increase, in consequence, the costs regarding its financing on a short term.

    This is the third of three papers (in addition to an introductory summary) aimed at providing a framework for evaluating future reductions or modifications of the U.S. nuclear force, first by considering previous instances in which nuclear-force capabilities were eliminated; second by looking forward into at least the foreseeable future at the features of global and regional deterrence (recognizing that new weapon systems currently projected will have expected lifetimes stretching beyond our ability to predict the future); and third by providing examples of past or possible undesirable outcomes in the shaping of the future nuclear force, as well as some closing thoughts for the future. In this paper, we provide one example each of our judgments on what constitutes a box canyon, a roach motel, and a wrong turn: Wrong Turn: The Reliable Replacement Warhead: Roach Motel: SRAM T vs the B61: and A Possible Box Canyon: A Low-Yield Version of the W76 SLBM Warhead. Recognizing that new nuclear missions or weapons are not demanded by current circumstances ₋ a development path that yields future capabilities similar to those of today, which are adequate if not always ideal, and a broader national-security strategy that supports nonproliferation and arms control by reducing the role for, and numbers, of nuclear weapons ₋ we briefly consider alternate, less desirable futures, and their possible effect on the complex problem of regional deterrence. In this regard, we discuss the issues posed by, and possible responses to, three example regional deterrence challenges: in-country defensive use of nuclear weapons by an adversary; reassurance of U.S. allies with limited strategic depth threatened by an emergent nuclear power; and extraterritorial, non-strategic offensive use of nuclear weapons by an adversary in support of limited military objectives against a U.S. ally.

  5. Malthus is still wrong: we can feed a world of 9-10 billion, but only by reducing food demand.

    Science.gov (United States)

    Smith, Pete

    2015-08-01

    In 1798, Thomas Robert Malthus published 'An essay on the principle of population' in which he concluded that: 'The power of population is so superior to the power of the earth to produce subsistence for man, that premature death must in some shape or other visit the human race.' Over the following century he was criticised for underestimating the potential for scientific and technological innovation to provide positive change. Since then, he has been proved wrong, with a number of papers published during the past few decades pointing out why he has been proved wrong so many times. In the present paper, I briefly review the main changes in food production in the past that have allowed us to continue to meet ever growing demand for food, and I examine the possibility of these same innovations delivering food security in the future. On the basis of recent studies, I conclude that technological innovation can no longer be relied upon to prove Malthus wrong as we strive to feed 9-10 billion people by 2050. Unless we are prepared to accept a wide range of significant, undesirable environmental consequences, technology alone cannot provide food security in 2050. Food demand, particularly the demand for livestock products, will need to be managed if we are to continue to prove Malthus wrong into the future.

  8. Assigning Priorities for Fixed Priority Preemption Threshold Scheduling

    Saehwa Kim

    2015-01-01

    Full Text Available Preemption threshold scheduling (PTS enhances real-time schedulability by controlling preemptiveness of tasks. This benefit of PTS highly depends on a proper algorithm that assigns each task feasible scheduling attributes, which are priority and preemption threshold. Due to the existence of an efficient optimal preemption threshold assignment algorithm that works with fully assigned priority orderings, we need an optimal priority assignment algorithm for PTS. This paper analyzes the inefficiency or nonoptimality of the previously proposed optimal priority assignment algorithms for PTS. We develop theorems for exhaustively but safely pruning infeasible priority orderings while assigning priorities to tasks for PTS. Based on the developed theorems, we correct the previously proposed optimal priority assignment algorithm for PTS. We also propose a performance improved optimal priority assignment algorithm for PTS proving its optimality. The empirical evaluation results clearly show the effectiveness of the proposed algorithm.

    2010-10-07

    Subject matter expert assessments can include both assignment and linguistic uncertainty. This paper examines assessments containing linguistic uncertainty associated with a qualitative description of a specific state of interest and the assignment uncertainty associated with assigning a qualitative value to that state. A Bayesian approach is examined to simultaneously quantify both assignment and linguistic uncertainty in the posterior probability. The approach is applied to a simplified damage assessment model involving both assignment and linguistic uncertainty. The utility of the approach and the conditions under which the approach is feasible are examined and identified.

  16. Quantum entanglement: facts and fiction - how wrong was Einstein after all?

    Science.gov (United States)

    Nordén, Bengt

    2016-01-01

    Einstein was wrong with his 1927 Solvay Conference claim that quantum mechanics is incomplete and incapable of describing diffraction of single particles. However, the Einstein-Podolsky-Rosen paradox of entangled pairs of particles remains lurking with its 'spooky action at a distance'. In molecules quantum entanglement can be viewed as basis of both chemical bonding and excitonic states. The latter are important in many biophysical contexts and involve coupling between subsystems in which virtual excitations lead to eigenstates of the total Hamiltonian, but not for the separate subsystems. The author questions whether atomic or photonic systems may be probed to prove that particles or photons may stay entangled over large distances and display the immediate communication with each other that so concerned Einstein. A dissociating hydrogen molecule is taken as a model of a zero-spin entangled system whose angular momenta are in principle possible to probe for this purpose. In practice, however, spins randomize as a result of interactions with surrounding fields and matter. Similarly, no experiment seems yet to provide unambiguous evidence of remaining entanglement between single photons at large separations in absence of mutual interaction, or about immediate (superluminal) communication. This forces us to reflect again on what Einstein really had in mind with the paradox, viz. a probabilistic interpretation of a wave function for an ensemble of identically prepared states, rather than as a statement about single particles. Such a prepared state of many particles would lack properties of quantum entanglement that make it so special, including the uncertainty upon which safe quantum communication is assumed to rest. An example is Zewail's experiment showing visible resonance in the dissociation of a coherently vibrating ensemble of NaI molecules apparently violating the uncertainty principle. Einstein was wrong about diffracting single photons where space-like anti

    2010-04-15

    Here we describe a new algorithm for automatically determining the mainchain sequential assignment of NMR spectra for proteins. Using only the customary triple resonance experiments, assignments can be quickly found for not only small proteins having rather complete data, but also for large proteins, even when only half the residues can be assigned. The result of the calculation is not the single best assignment according to some criterion, but rather a large number of satisfactory assignments that are summarized in such a way as to help the user identify portions of the sequence that are assigned with confidence, vs. other portions where the assignment has some correlated alternatives. Thus very imperfect initial data can be used to suggest future experiments.

    Initial results on wrong-sign $D^0 \\rightarrow K^+ \\pi^-$ decays based on the 2010 dataset are presented: the selection criteria, the yield, the time-integrated ratio of wrong-sign to right-sign ($D^0 \\rightarrow K^- \\pi^+$) decays, and a decay time acceptance corrected ratio. The corrected ratio is measured to be $R_{acc \\, cor} = (0.409 \\pm 0.031 (stat.) \\pm 0.039 (sys.)) \\%$. This analysis is the first step towards the measurement of the time-dependent wrong-sign/right-sign ratio from which $D^0$ mixing parameters may be extracted.

    The essays in this book look at way in which the fundaments of physics might need to be changed in order to make progress towards a unified theory. They are based on the prize-winning essays submitted to the FQXi essay competition “Which of Our Basic Physical Assumptions Are Wrong?”, which drew over 270 entries. As Nobel Laureate physicist Philip W. Anderson realized, the key to understanding nature’s reality is not anything “magical”, but the right attitude, “the focus on asking the right questions, the willingness to try (and to discard) unconventional answers, the sensitive ear for phoniness, self-deception, bombast, and conventional but unproven assumptions.” The authors of the eighteen prize-winning essays have, where necessary, adapted their essays for the present volume so as to (a) incorporate the community feedback generated in the online discussion of the essays, (b) add new material that has come to light since their completion and (c) to ensure accessibility to a broad audience of re...

In particular, for small WSI and MSI, WSI was shown to have twice the impact of MSI for both reliability and gain, and the impact of both WSI and MSI increased as the reliability of predicting merit with perfect information decreased. The overall impact on the efficiency of gain for small WSI and MS...

  3. The Two-Wrongs model explains perception-action dissociations for illusions driven by distortions of the egocentric reference frame

    Full Text Available Several studies have demonstrated a dissociation of the effects of illusion on perception and action, with perception generally reported to be susceptible to illusions, while actions are seemingly immune. These findings have been interpreted to support Milner and Goodale's Two Visual Systems model, which proposes the existence of separate visual processing streams for perception and action. However, an alternative interpretation suggests that this type of behavioral dissociation will occur for any illusion that is caused by a distortion of the observer's egocentric reference frame, without requiring the existence of separate perception and action systems that are differently affected by the illusion. In this scenario, movements aimed at illusory targets will be accurate if they are guided within the same distorted reference frame used for target encoding, since the error of motor guidance will cancel with the error of encoding (hence, for actions, two wrongs do make a right. We further test this Two-Wrongs model by examining two illusions for which the hypothesis makes very different predictions: the rod-and-frame illusion (which affects perception but not actions and the simultaneous-tilt illusion (which affects perception and actions equally. We demonstrate that the rod-and-frame illusion is caused by a distortion of the observer's egocentric reference frame suitable for the cancellation of errors predicted by the Two-Wrongs model. In contrast, the simultaneous-tilt illusion is caused by local interactions between stimulus elements within an undistorted reference frame, precluding the cancellation of errors associated with the Two-Wrongs model such that the illusion is reflected in both perception and actions. These results provide evidence for a class of illusions that lead to dissociations of perception and action through distortions of the observer's spatial reference frame, rather than through the actions of functionally separate visual

  5. Nuclear power is neither right nor wrong: the case for a tertium datur in the ethics of technology.

    Hillerbrand, Rafaela; Peterson, Martin

    2014-06-01

    The debate over the civilian use of nuclear power is highly polarised. We argue that a reasonable response to this deep disagreement is to maintain that advocates of both camps should modify their positions. According to the analysis we propose, nuclear power is neither entirely right nor entirely wrong, but rather right and wrong to some degree. We are aware that this non-binary analysis of nuclear power is controversial from a theoretical point of view. Utilitarians, Kantians, and other moral theorists make sharp, binary distinctions between right and wrong acts. However, an important argument speaking in favour of our non-binary analysis is that it better reflects our considered intuitions about the ethical trade-offs we face in discussions of nuclear power. The aim of this article is to make this argument sharp by explaining how it can be rendered compatible with, and supported by, the Capability Approach, which is quickly becoming one of the most influential frameworks for thinking about human development.

  7. Protein Side-Chain Resonance Assignment and NOE Assignment Using RDC-Defined Backbones without TOCSY Data3

    Science.gov (United States)

    Zeng, Jianyang; Zhou, Pei; Donald, Bruce Randall

    2011-01-01

    One bottleneck in NMR structure determination lies in the laborious and time-consuming process of side-chain resonance and NOE assignments. Compared to the well-studied backbone resonance assignment problem, automated side-chain resonance and NOE assignments are relatively less explored. Most NOE assignment algorithms require nearly complete side-chain resonance assignments from a series of through-bond experiments such as HCCH-TOCSY or HCCCONH. Unfortunately, these TOCSY experiments perform poorly on large proteins. To overcome this deficiency, we present a novel algorithm, called NASCA (NOE Assignment and Side-Chain Assignment), to automate both side-chain resonance and NOE assignments and to perform high-resolution protein structure determination in the absence of any explicit through-bond experiment to facilitate side-chain resonance assignment, such as HCCH-TOCSY. After casting the assignment problem into a Markov Random Field (MRF), NASCA extends and applies combinatorial protein design algorithms to compute optimal assignments that best interpret the NMR data. The MRF captures the contact map information of the protein derived from NOESY spectra, exploits the backbone structural information determined by RDCs, and considers all possible side-chain rotamers. The complexity of the combinatorial search is reduced by using a dead-end elimination (DEE) algorithm, which prunes side-chain resonance assignments that are provably not part of the optimal solution. Then an A* search algorithm is employed to find a set of optimal side-chain resonance assignments that best fit the NMR data. These side-chain resonance assignments are then used to resolve the NOE assignment ambiguity and compute high-resolution protein structures. Tests on five proteins show that NASCA assigns resonances for more than 90% of side-chain protons, and achieves about 80% correct assignments. The final structures computed using the NOE distance restraints assigned by NASCA have backbone RMSD 0

  8. Ant Colony Algorithm and Simulation for Robust Airport Gate Assignment

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Airport gate assignment is core task for airport ground operations. Due to the fact that the departure and arrival time of flights may be influenced by many random factors, the airport gate assignment scheme may encounter gate conflict and many other problems. This paper aims at finding a robust solution for airport gate assignment problem. A mixed integer model is proposed to formulate the problem, and colony algorithm is designed to solve this model. Simulation result shows that, in consideration of robustness, the ability of antidisturbance for airport gate assignment scheme has much improved.

  9. The Impact of Adding Online Homework Assignments to an Introduction to Physical Geology Class

    Science.gov (United States)

    Brevik, Eric C.

    2017-04-01

    As instructors we are constantly looking for ways to improve student performance in the classroom. In an attempt to improve student performance in my GEOL 105 - Introduction to Physical Geology class, I added online homework assignments from the Pearson Mastering Geology program beginning in the Fall semester of 2014. There were several anticipated advantages to the online homework approach. If a student is struggling with a question they can get hints that don't tell them the answer, but are designed to stimulate their thinking and lead them towards the correct answer. The students also know immediately after submitting their answers which questions they got right and which were wrong, and they can go back to the wrong answers and try to determine the correct answer so they know what it is. This gives them much more rapid feedback than traditional paper homework, all of which makes this a more student-centered approach to learning. It is also my hope that the students find the online homework more interesting and interactive than paper-based homework, which I hope in turn will stimulate the students to be more likely to do the homework and take it seriously while also having some fun while doing it. As of the end of Fall semester 2016, I had been using the online homework assignments in my classes for three years. Therefore, I analyzed student performance in the three years prior to adopting the online homework and compared it to performance over the three years since adopting online homework. In the three years prior to adopting the online homework, the average grade in my classes was 73.8%; afterwards the average grade was 81.3%, for an improvement of 7.5% on average. Most of that improvement was in average test scores, which increased by 6.3% (67.4% prior to 73.6% after). The online homework did not improve the performance of the top students, but it did improve the performance of the other students. Prior to adopting the online homework, grade distribution in

  10. 'Wrong parents' and 'right parents': shared perspectives about citizen participation in policy implementation.

    Potter, Deborah Anne

    2010-06-01

    Government policies, both in Europe and the U.S., increasingly mandate that community-based citizens partner with professionals to plan and implement policy-relevant programs. In the U.S., parents of children with serious emotional disturbances may participate in Community Collaboratives which are charged with implementing children's mental health policy in local communities. This qualitative study examined three Community Collaboratives and identified organizational features associated with how the groups prioritized lay involvement, among other competing goals which they legitimately could pursue. Thirty-four key informants participated in in-depth interviews. Although the overall study identified several factors which permitted greater and lesser degrees of family involvement, this paper reports on one: the symbolic meaning shared by members about lay participation in their shared perspectives about "wrong parents" and "right parents." Furthermore, two alternate types of "right parents" identified a psychologized version of parents as consumers, and a civic vision of parents as partners. Results from this study are applicable to a wide array of lay-professional partnerships. This study suggests that in order to foster lay-professional partnerships in policy initiatives, lay participants must possess additional, civic-based skills, beyond those needed in the service delivery arena. Furthermore, organizational and professional change may be required to address professional dominance. Within mental health, lack of acceptance of nationally touted recovery-based models is a significant barrier. Finally, sociological implications of developing a civic-based framework for lay-professional partnerships are discussed. Copyright 2010 Elsevier Ltd. All rights reserved.

  11. Narrative Acts: Telling Tales of Life and Love with the Wrong Gender

    Directory of Open Access Journals (Sweden)

    James Valentine

    2008-05-01

    Full Text Available This presentation provides an illustration of performative social science through the world's first project to focus on multi-media storytelling with a nationwide LGBT community for public representation and museum archiving. Where voices are unheard, hidden or suppressed, the images and representations of a community may be stereotyped and discriminatory, constructed about the community by those on the outside. LGBT (lesbian, gay, bisexual and transgender people have experienced social exclusion and marginalisation, and their stories have been neglected or distorted. Their lives and loves have been characterised as wrong: mistaken in medical or moral terms. OurStory Scotland was established to research, record and celebrate the history and experiences of the LGBT community through their own words. Our approach combines action research and performative social science: it is participatory and emancipatory, developing the knowledge of a community through various modes of storytelling performance. This presentation reviews storytelling methods and themes, that have relevance for marginalised communities where disclosure may be problematic. The narrative acts that make up our stories range from one-liners, through written episodes, to oral history recordings, stories shared in group storytelling and narrative exchange, tales told with and through images, "text out" visual displays, "supporting stars" mapping support as an alternative to the conventional family tree, dramatisation and ceilidh performance. The stories challenge fixed and stereotyped identities, and reveal the centrality of storytelling to leading our lives. They also illustrate the rewards of performative action social research, both for a community researching itself and for dissemination more widely. URN: urn:nbn:de:0114-fqs0802491

    2016-01-01

    Pre-class reading assignments help prepare students for active classes by providing a first exposure to the terms and concepts to be used during class. We investigate if the use of inquiry-oriented PhET-based activities in conjunction with pre-class reading assignments can improve both the preparation of students for in-class learning and student attitudes towards and engagement with pre-class assignments. Over three course modules covering different topics, students were assigned randomly to complete either a textbook-only pre-class assignment or both a textbook pre-class assignment and a PhET-based activity. The assignments helped prepare students for class, as measured by performance on the pre-class quiz relative to a beginning-of-semester pre-test, but no evidence for increased learning due the PhET activity was observed. Students rated the assignments which included PhET as more enjoyable and, for the topic latest in the semester, reported engaging more with the assignments when PhET was included.

  4. Multiobjective Gate Assignment Based on Passenger Walking Distance and Fairness

    Directory of Open Access Journals (Sweden)

    Yu Jiang

    2013-01-01

    Full Text Available Passenger walking distance is an important index of the airport service quality. How to shorten the walking distance and balance the airlines' service quality is the focus of much research on airport gate assignment problems. According to the problems of airport passenger service quality, an optimization gate assignment model is established. The gate assignment model is based on minimizing the total walking distance of all passengers and balancing the average walking distance of passengers among different airlines. Lingo is used in the simulation of a large airport gate assignment. Test results show that the optimization model can reduce the average walking distance of passenger effectively, improve the number of flights assigned to gate, balance airline service quality, and enhance the overall service level of airports and airlines. The model provides reference for the airport gate preassignment.

  5. Wavelength Assignment in Hybrid Quantum-Classical Networks.

    Science.gov (United States)

    Bahrani, Sima; Razavi, Mohsen; Salehi, Jawad A

    2018-02-22

    Optimal wavelength assignment in dense-wavelength-division-multiplexing (DWDM) systems that integrate both quantum and classical channels is studied. In such systems, weak quantum key distribution (QKD) signals travel alongside intense classical signals on the same fiber, where the former can be masked by the background noise induced by the latter. Here, we investigate how optimal wavelength assignment can mitigate this problem. We consider different DWDM structures and various sources of crosstalk and propose several near-optimal wavelength assignment methods that maximize the total secret key rate of the QKD channels. Our numerical results show that the optimum wavelength assignment pattern is commonly consisted of several interspersed quantum and classical bands. Using our proposed techniques, the total secret key rate of quantum channels can substantially be improved, as compared to conventional assignment methods, in the noise dominated regimes. Alternatively, we can maximize the number of QKD users supported under certain key rate constraints.

    TANGO is one of the most accurate tools for the taxonomic assignment of sequence reads. However, because of the differences in the taxonomy structures, performing a taxonomic assignment on different reference taxonomies will produce divergent results. We have improved the TANGO pipeline to be able to perform the taxonomic assignment of a metagenomic sample using alternative reference taxonomies, coming from different sources. We highlight the novel pre-processing step, necessary to accomplish this task, and describe the improvements in the assignment process. We present the new TANGO pipeline in details, and, finally, we show its performance on four real metagenomic datasets and also on synthetic datasets. The new version of TANGO, including implementation improvements and novel developments to perform the assignment on different reference taxonomies, is freely available at http://sourceforge.net/projects/taxoassignment/.

  7. Strategies to avoid wrongly labelled genomes using as example the detected wrong taxonomic affiliation for aeromonas genomes in the GenBank database.

    Roxana Beaz-Hidalgo

    Full Text Available Around 27,000 prokaryote genomes are presently deposited in the Genome database of GenBank at the National Center for Biotechnology Information (NCBI and this number is exponentially growing. However, it is not known how many of these genomes correspond correctly to their designated taxon. The taxonomic affiliation of 44 Aeromonas genomes (only five of these are type strains deposited at the NCBI was determined by a multilocus phylogenetic analysis (MLPA and by pairwise average nucleotide identity (ANI. Discordant results in relation to taxa assignation were found for 14 (35.9% of the 39 non-type strain genomes on the basis of both the MLPA and ANI results. Data presented in this study also demonstrated that if the genome of the type strain is not available, a genome of the same species correctly identified can be used as a reference for ANI calculations. Of the three ANI calculating tools compared (ANI calculator, EzGenome and JSpecies, EzGenome and JSpecies provided very similar results. However, the ANI calculator provided higher intra- and inter-species values than the other two tools (differences within the ranges 0.06-0.82% and 0.92-3.38%, respectively. Nevertheless each of these tools produced the same species classification for the studied Aeromonas genomes. To avoid possible misinterpretations with the ANI calculator, particularly when values are at the borderline of the 95% cutoff, one of the other calculation tools (EzGenome or JSpecies should be used in combination. It is recommended that once a genome sequence is obtained the correct taxonomic affiliation is verified using ANI or a MLPA before it is submitted to the NCBI and that researchers should amend the existing taxonomic errors present in databases.

    Full Text Available Context: The developed scheme allows carrying out the assignment of several frequency channels (both contiguous and not contiguous available to the secondary users that require a higher bandwidth, under an environment of equality. Objective: The following paper develops a multichannel assignment which allows taking in a more efficient way the spectral opportunities in cognitive radio networks. Method: The developed assignment model is composed by the K-Means algorithm, which is in charged of carrying out the grouping of channels through clusters for the best parameters, and another algorithm in charge of establishing an equal criteria for all the secondary users that wish to transmit. The reached results were evaluated with experimental spectral occupancy data taken from the GSM frequency band. The developed model was compared with the MFA-CRN algorithm. Results: The obtained measurements correspond to the average bandwidth, the average delay, and the fairness calculation in the assignment of several channels. The developed assignment model shows an improvement in the assignment of a higher transmission average bandwidth for each secondary user while maintaining the fairness criteria in the channel assignments. Conclusion: Despite the increasing in the number of handoffs, it is also observed that metrics such as average bandwidth, average throughput and average delay are never negatively impacted by this increase in handoffs.

    Full Text Available Fashion industry has variety products, so the multi-skilled workers are required to improve flexibility in production and assignment. Generally the supervisor will assign task to the workers based on skill and skill levels of worker. Since in fashion industry new product styles are launched more frequently and the order size tends to be smaller, the workers always learn when the raw material and the production process changes. Consequently they require less time to produce the succeeding units of a task based on their learning ability. Since the workers have both experience and inexperience workers, so each worker has different skill level and learning ability. Consequently, the assignment which assumed constant skill level is not proper to use. This paper proposes a task-worker assignment considering worker skill levels and learning abilities. Processing time of each worker changes along production period due to a worker learning ability. We focus on a task-worker assignment in a fashion industry where tasks are ordered in series; the number of tasks is greater than the number of workers. Therefore, workers can perform multiple assignments followed the precedence restriction as an assembly line balancing problem. The problem is formulated in an integer linear programming model with objective to minimize makespan. A heuristic is proposed to determine the lower bound (LB and the upper bound (UB of the problem and the best assignment is determined. The performance of the heuristic method is tested by comparing quality of solution and computational time to optimal solutions.

    For some species, animal production systems are based on the use of crossbreeding to take advantage of the increased performance of crossbred compared to purebred animals. Effects of single nucleotide polymorphisms (SNPs) may differ between purebred and crossbred animals for several reasons: (1) differences in linkage disequilibrium between SNP alleles and a quantitative trait locus; (2) differences in genetic backgrounds (e.g., dominance and epistatic interactions); and (3) differences in environmental conditions, which result in genotype-by-environment interactions. Thus, SNP effects may be breed-specific, which has led to the development of genomic evaluations for crossbred performance that take such effects into account. However, to estimate breed-specific effects, it is necessary to know breed origin of alleles in crossbred animals. Therefore, our aim was to develop an approach for assigning breed origin to alleles of crossbred animals (termed BOA) without information on pedigree and to study its accuracy by considering various factors, including distance between breeds. The BOA approach consists of: (1) phasing genotypes of purebred and crossbred animals; (2) assigning breed origin to phased haplotypes; and (3) assigning breed origin to alleles of crossbred animals based on a library of assigned haplotypes, the breed composition of crossbred animals, and their SNP genotypes. The accuracy of allele assignments was determined for simulated datasets that include crosses between closely-related, distantly-related and unrelated breeds. Across these scenarios, the percentage of alleles of a crossbred animal that were correctly assigned to their breed origin was greater than 90 %, and increased with increasing distance between breeds, while the percentage of incorrectly assigned alleles was always less than 2 %. For the remaining alleles, i.e. 0 to 10 % of all alleles of a crossbred animal, breed origin could not be assigned. The BOA approach accurately assigns

    This note analytically derives the impact that wrong and missing sire information (WSI and MSI, respectively) has on the reliability of predicting merit and gain compared with perfect information. In particular, for small WSI and MSI, WSI was shown to have twice the impact of MSI for both reliability and gain, and the impact of both WSI and MSI increased as the reliability of predicting merit with perfect information decreased. The overall impact on the efficiency of gain for small WSI and MSI was half the overall impact on reliability.

    2007-01-01

    This preliminary study examines the impact of conceptual writing assignments on student understanding of two physics concepts. Writing assignments covered the concepts of Newton's Third Law and the impulse-momentum relationship and were given to students in both high school and college level introductory physics classes. The students in these classes along with students in classes taught in an identical fashion by the same instructors without the addition of writing assignments were tested on their conceptual understanding of the two content areas. The results of this initial study indicate that the efficacy of this approach varied with topic. This study further indicates that students' benefit from the writing assignments was independent of their writing ability.

    Calibrated Peer Review ??? (CPR), a web-based instructional tool developed as part of the National Science Foundation reform initiatives in undergraduate science education, allows instructors to incorporate multiple writing assignments in large courses without overwhelming the instructor. This study reports successful implementation of CPR in a large, introductory geology course and student learning of geoscience content. For each CPR assignment in this study, students studied web-based and paper resources, wrote an essay, and reviewed seven essays (three from the instructor, three from peers, and their own) on the topic. Although many students expressed negative attitudes and concerns, particularly about the peer review process of this innovative instructional approach, they also recognized the learning potential of completing CPR assignments. Comparing instruction on earthquakes and plate boundaries using a CPR assignment vs. an instructional video lecture and homework essay with extensive instructor feedback, students mastered more content via CPR instruction.

    In complex environments, many potential cues can guide a decision or be assigned responsibility for the outcome of the decision. We know little, however, about how humans and animals select relevant information sources that should guide behavior. We show that subjects solve this relevance selection and credit assignment problem by selecting one cue and its association with a particular outcome as the main focus of a hypothesis. To do this, we examined learning while using a task design that allowed us to estimate the focus of each subject's hypotheses on a trial-by-trial basis. When a prediction is confirmed by the outcome, then credit for the outcome is assigned to that cue rather than an alternative. Activity in medial frontal cortex is associated with the assignment of credit to the cue that is the main focus of the hypothesis. However, when the outcome disconfirms a prediction, the focus shifts between cues, and the credit for the outcome is assigned to an alternative cue. This process of reselection for credit assignment to an alternative cue is associated with lateral orbitofrontal cortex. SIGNIFICANCE STATEMENT Learners should infer which features of environments are predictive of significant events, such as rewards. This “credit assignment” problem is particularly challenging when any of several cues might be predictive. We show that human subjects solve the credit assignment problem by implicitly “hypothesizing” which cue is relevant for predicting subsequent outcomes, and then credit is assigned according to this hypothesis. This process is associated with a distinctive pattern of activity in a part of medial frontal cortex. By contrast, when unexpected outcomes occur, hypotheses are redirected toward alternative cues, and this process is associated with activity in lateral orbitofrontal cortex. PMID:26818500

  4. NMR assignments of sparsely labeled proteins using a genetic algorithm.

    2017-04-01

    Sparse isotopic labeling of proteins for NMR studies using single types of amino acid ((15)N or (13)C enriched) has several advantages. Resolution is enhanced by reducing numbers of resonances for large proteins, and isotopic labeling becomes economically feasible for glycoproteins that must be expressed in mammalian cells. However, without access to the traditional triple resonance strategies that require uniform isotopic labeling, NMR assignment of crosspeaks in heteronuclear single quantum coherence (HSQC) spectra is challenging. We present an alternative strategy which combines readily accessible NMR data with known protein domain structures. Based on the structures, chemical shifts are predicted, NOE cross-peak lists are generated, and residual dipolar couplings (RDCs) are calculated for each labeled site. Simulated data are then compared to measured values for a trial set of assignments and scored. A genetic algorithm uses the scores to search for an optimal pairing of HSQC crosspeaks with labeled sites. While none of the individual data types can give a definitive assignment for a particular site, their combination can in most cases. Four test proteins previously assigned using triple resonance methods and a sparsely labeled glycosylated protein, Robo1, previously assigned by manual analysis, are used to validate the method and develop a criterion for identifying sites assigned with high confidence.

    2008-01-01

    Homework assignments are an indispensable part of cognitive-behavioural therapy. During the past two decades, a growing number of studies have shed light on its characteristics and effects. However, most studies primarily consider the therapists' view, and little is known about the use of supportive strategies to implement homework assignments in psychotherapy and about patients' attitudes towards regular assignments. To fill this gap, we assessed the attitudes towards homework assignments of 80 outpatients. In addition, those who had received a task during the past session (75%) were asked to report characteristics of their task as well as therapists' behaviour strategies during the assignment of the task. One week later, therapists rated the extent of completion of the task. Results showed that the patients generally had a positive attitude towards homework and that they accomplished most of the tasks. With regard to the therapists' behaviour during the assignment of the task, there seems to be room for improvement. Copyright (c) 2008 John Wiley & Sons, Ltd.

    Full Text Available Among the casualties in the ‘war on terror’ is the presumption of innocence. It is now known that four Canadians who were the subject of investigation by the RCMP and CSIS were detained and tortured in Syria on the basis of information that originated in and was shared by Canada. None has ever been charged with a crime. On their return home, all four men called for a process that would expose the truth about the role of Canadian agencies in what happened to them, and ultimately help them clear their names and rebuild their lives. To date, in varying degrees, all four men continue to wait for that “process.” In this paper, I examine the access to justice mechanisms available to persons who are wrongfully accused of being involved in terrorist activities. Utilizing the case study of one of the four men, Abdullah Almalki, I explore the various processes available to him: (i a complaint to the relevant domestic complaints bodies, the Security Intelligence Review Committee and the Commission for Public Complaints Against the RCMP; (ii a commission of inquiry; and (iii a civil tort claim. Due in large part to the role national security confidentiality plays in these mechanisms, all three models are found to be ineffective for those seeking accountability in the national security context. Parmi les victimes de la «guerre contre le terrorisme» figure la présomption d’innocence. On sait maintenant que quatre Canadiens qui ont fait l’objet d’enquêtes par la GRC et le SCRS ont été détenus et torturés en Syrie suite à des renseignements ayant leur origine au Canada et partagés par le Canada. Nul d’entre eux n’a jamais été accusé de crime. À leur retour, tous les quatre hommes ont demandé un processus qui exposerait la vérité au sujet du rôle d’agences canadiennes dans ce qui leur est arrivé et qui éventuellement leur aiderait à rétablir leur réputation et refaire leur vie.

  7. A Bayesian Assignment Method for Ambiguous Bisulfite Short Reads.

    Directory of Open Access Journals (Sweden)

    Hong Tran

    Full Text Available DNA methylation is an epigenetic modification critical for normal development and diseases. The determination of genome-wide DNA methylation at single-nucleotide resolution is made possible by sequencing bisulfite treated DNA with next generation high-throughput sequencing. However, aligning bisulfite short reads to a reference genome remains challenging as only a limited proportion of them (around 50-70% can be aligned uniquely; a significant proportion, known as multireads, are mapped to multiple locations and thus discarded from downstream analyses, causing financial waste and biased methylation inference. To address this issue, we develop a Bayesian model that assigns multireads to their most likely locations based on the posterior probability derived from information hidden in uniquely aligned reads. Analyses of both simulated data and real hairpin bisulfite sequencing data show that our method can effectively assign approximately 70% of the multireads to their best locations with up to 90% accuracy, leading to a significant increase in the overall mapping efficiency. Moreover, the assignment model shows robust performance with low coverage depth, making it particularly attractive considering the prohibitive cost of bisulfite sequencing. Additionally, results show that longer reads help improve the performance of the assignment model. The assignment model is also robust to varying degrees of methylation and varying sequencing error rates. Finally, incorporating prior knowledge on mutation rate and context specific methylation level into the assignment model increases inference accuracy. The assignment model is implemented in the BAM-ABS package and freely available at https://github.com/zhanglabvt/BAM_ABS.

    The significant biological role of RNA has further highlighted the need for improving the accuracy, efficiency and the reach of methods for investigating RNA structure and function. Nuclear magnetic resonance (NMR) spectroscopy is vital to furthering the goals of RNA structural biology because of its distinctive capabilities. However, the dispersion pattern in the NMR spectra of RNA makes automated resonance assignment, a key step in NMR investigation of biomolecules, remarkably challenging. Herein we present RNA Probabilistic Assignment of Imino Resonance Shifts (RNA-PAIRS), a method for the automated assignment of RNA imino resonances with synchronized verification and correction of predicted secondary structure. RNA-PAIRS represents an advance in modeling the assignment paradigm because it seeds the probabilistic network for assignment with experimental NMR data, and predicted RNA secondary structure, simultaneously and from the start. Subsequently, RNA-PAIRS sets in motion a dynamic network that reverberates between predictions and experimental evidence in order to reconcile and rectify resonance assignments and secondary structure information. The procedure is halted when assignments and base-parings are deemed to be most consistent with observed crosspeaks. The current implementation of RNA-PAIRS uses an initial peak list derived from proton-nitrogen heteronuclear multiple quantum correlation ({sup 1}H-{sup 15}N 2D HMQC) and proton-proton nuclear Overhauser enhancement spectroscopy ({sup 1}H-{sup 1}H 2D NOESY) experiments. We have evaluated the performance of RNA-PAIRS by using it to analyze NMR datasets from 26 previously studied RNAs, including a 111-nucleotide complex. For moderately sized RNA molecules, and over a range of comparatively complex structural motifs, the average assignment accuracy exceeds 90%, while the average base pair prediction accuracy exceeded 93%. RNA-PAIRS yielded accurate assignments and base pairings consistent with imino

  9. Constrained Task Assignment and Scheduling On Networks of Arbitrary Topology

    Science.gov (United States)

    Jackson, Justin Patrick

    This dissertation develops a framework to address centralized and distributed constrained task assignment and task scheduling problems. This framework is used to prove properties of these problems that can be exploited, develop effective solution algorithms, and to prove important properties such as correctness, completeness and optimality. The centralized task assignment and task scheduling problem treated here is expressed as a vehicle routing problem with the goal of optimizing mission time subject to mission constraints on task precedence and agent capability. The algorithm developed to solve this problem is able to coordinate vehicle (agent) timing for task completion. This class of problems is NP-hard and analytical guarantees on solution quality are often unavailable. This dissertation develops a technique for determining solution quality that can be used on a large class of problems and does not rely on traditional analytical guarantees. For distributed problems several agents must communicate to collectively solve a distributed task assignment and task scheduling problem. The distributed task assignment and task scheduling algorithms developed here allow for the optimization of constrained military missions in situations where the communication network may be incomplete and only locally known. Two problems are developed. The distributed task assignment problem incorporates communication constraints that must be satisfied; this is the Communication-Constrained Distributed Assignment Problem. A novel distributed assignment algorithm, the Stochastic Bidding Algorithm, solves this problem. The algorithm is correct, probabilistically complete, and has linear average-case time complexity. The distributed task scheduling problem addressed here is to minimize mission time subject to arbitrary predicate mission constraints; this is the Minimum-time Arbitrarily-constrained Distributed Scheduling Problem.

    Full Text Available The construct alternative assessment has been widely used in higher education. It is often defined as any type of assessment of learners who provide a response to an assignment. The key features of alternative assessment are active participation of learners in self-evaluation of their performance, and the development of reflective thinking through reflective thinking (Schön, 1983. The success of alternative assessment in language teaching is predetermined by student’s performance and demonstrates learner’s language proficiency in contemporary communicative classrooms. This paper aims at researching the influence of students’ evaluations of various assignments for their linguistic development in English for Specific Purposes (ESP. The study uses learners’ assessment of different assignments and learners’ in-course and post-course written reflections on benefits to language mastery. Learners’ assignments included were contributions to portfolios (dossiers, such as essays and summaries, oral presentations, short impromptu talks, creative tasks, tests, and self-assessment notes (reflections on activities in learning ESP. Findings were obtained for two streams of the project participants. Results showed that self-assessment was beneficial for learners’ linguistic development. The context of learners’ reflections reveals that the attitudes to various assignments are affected by success or failure in students’ performance. Reflective practice might help teachers develop ways of dealing with previously identified difficulties and improve the quality of teaching.

    Wildlife forensic science has become a key means of enforcing legislation surrounding the illegal trade in protected and endangered species. A relatively new dimension to this area of forensic science is to determine the geographic origin of a seized sample. This review focuses on DNA testing, which relies on assignment of an unknown sample to its genetic population of origin. Key examples of this are the trade in timber, fish and ivory and these are used only to illustrate the large number of species for which this type of testing is potentially available. The role of mitochondrial and nuclear DNA markers is discussed, alongside a comparison of neutral markers with those exhibiting signatures of selection, which potentially offer much higher levels of assignment power to address specific questions. A review of assignment tests is presented along with detailed methods for evaluating error rates and considerations for marker selection. The availability and quality of reference data are of paramount importance to support assignment applications and ensure reliability of any conclusions drawn. The genetic methods discussed have been developed initially as investigative tools but comment is made regarding their use in courts. The potential to compliment DNA markers with elemental assays for greater assignment power is considered and finally recommendations are made for the future of this type of testing.

    We tested the hypothesis that engagement in a few, brief writing assignments in a nonmajors science course can improve student ability to convey critical thought about science. A sample of three papers written by students (n = 30) was coded for presence and accuracy of elements related to scientific writing. Scores for different aspects of scientific writing were significantly correlated, suggesting that students recognized relationships between components of scientific thought. We found that students' ability to write about science topics and state conclusions based on data improved over the course of three writing assignments, while the abilities to state a hypothesis and draw clear connections between human activities and environmental impacts did not improve. Three writing assignments generated significant change in student ability to write scientifically, although our results suggest that three is an insufficient number to generate complete development of scientific writing skills.

    A fundamental goal of motor learning is to establish the neural patterns that produce a desired behavioral outcome. It remains unclear how and when the nervous system solves this 'credit assignment' problem. Using neuroprosthetic learning, in which we could control the causal relationship between neurons and behavior, we found that sleep-dependent processing was required for credit assignment and the establishment of task-related functional connectivity reflecting the casual neuron-behavior relationship. Notably, we observed a strong link between the microstructure of sleep reactivations and credit assignment, with downscaling of non-causal activity. Decoupling of spiking to slow oscillations using optogenetic methods eliminated rescaling. Thus, our results suggest that coordinated firing during sleep is essential for establishing sparse activation patterns that reflect the causal neuron-behavior relationship.

  15. Lexical stress assignment as a problem of probabilistic inference.

    Science.gov (United States)

    Jouravlev, Olessia; Lupker, Stephen J

    2015-10-01

    A new conceptualization of the process of stress assignment, couched in the principles of (Bayesian) probabilistic inference, is introduced in this paper. According to this approach, in deciding where to place stress in a polysyllabic word, a reader estimates the posterior probabilities of alternative stress patterns. This estimation is accomplished by adjusting a prior belief about the likelihoods of alternative stress patterns (derived from experience with the distribution of stress patterns in the language) by using lexical and non-lexical sources of evidence for stress derived from the orthographic input. The proposed theoretical framework was used to compute probabilities of stress patterns for Russian disyllabic words and nonwords which were then compared with the performance of readers. The results showed that the estimated probabilities of stress patterns were reflective of actual stress assignment performance and of naming latencies, suggesting that the mechanisms that are involved in the process of stress assignment might indeed be inferentially-based.

  16. Task Assignment Heuristics for Parallel and Distributed CFD Applications

    Science.gov (United States)

    Lopez-Benitez, Noe; Djomehri, M. Jahed; Biswas, Rupak

    2003-01-01

    This paper proposes a task graph (TG) model to represent a single discrete step of multi-block overset grid computational fluid dynamics (CFD) applications. The TG model is then used to not only balance the computational workload across the overset grids but also to reduce inter-grid communication costs. We have developed a set of task assignment heuristics based on the constraints inherent in this class of CFD problems. Two basic assignments, the smallest task first (STF) and the largest task first (LTF), are first presented. They are then systematically costs. To predict the performance of the proposed task assignment heuristics, extensive performance evaluations are conducted on a synthetic TG with tasks defined in terms of the number of grid points in predetermined overlapping grids. A TG derived from a realistic problem with eight million grid points is also used as a test case.

  17. A Stone Resource Assignment Model under the Fuzzy Environment

    Directory of Open Access Journals (Sweden)

    Liming Yao

    2012-01-01

    to tackle a stone resource assignment problem with the aim of decreasing dust and waste water emissions. On the upper level, the local government wants to assign a reasonable exploitation amount to each stone plant so as to minimize total emissions and maximize employment and economic profit. On the lower level, stone plants must reasonably assign stone resources to produce different stone products under the exploitation constraint. To deal with inherent uncertainties, the object functions and constraints are defuzzified using a possibility measure. A fuzzy simulation-based improved simulated annealing algorithm (FS-ISA is designed to search for the Pareto optimal solutions. Finally, a case study is presented to demonstrate the practicality and efficiency of the model. Results and a comparison analysis are presented to highlight the performance of the optimization method, which proves to be very efficient compared with other algorithms.

    Full Text Available Due to the low cost of CMOS IP-based cameras, wireless surveillance sensor networks have emerged as a new application of sensor networks able to monitor public or private areas or even country borders. Since these networks are bandwidth intensive and the radioelectric spectrum is limited, especially in unlicensed bands, it is mandatory to assign frequency channels in a smart manner. In this work, we propose the application of automated negotiation techniques for frequency assignment. Results show that these techniques are very suitable for the problem, being able to obtain the best solutions among the techniques with which we have compared them.

    Okinaka, H.; Yasuda, Y.; Hirata, Y.

    1984-04-01

    This paper addresses frequency assignment for single-level and multilevel SCPC systems. In order to obtain the optimum channel allocation, where the influence of intermodulation noise on carriers is minimized, a practical and effective method is proposed. The quasi-optimum solutions obtained with the proposed method are presented for single-level SCPC systems, showing their advantage in intermodulation noise reduction. Concerning frequency assignment for multilevel SCPC systems, two strategies to realize the quasi-optimum channel allocation are compared with regard to the improvement in carrier-to-intermodulation noise power ratio. The performance of the obtained channel allocation indicates the effectiveness of the proposed optimization method.

    2017-09-01

    Full Text Available By means of Piaget's critical clinical method, the study investigated the meanings assigned to mistakes by four students in different activities and interactive situations. The research also analyzed the results of using self-regulatory situations in understanding mistakes initially committed by the students. Data collection instruments consisted of games, video recordings, diaries and interviews. Following intervention, the students were able to recognize their competence, establish positive interactions within the group, and avoid viewing mistakes as obstacles to learning. We concluded that the meanings assigned to mistakes depend on certain variables, among them feelings nurtured by the individuals about themselves, the other, and the object of knowledge.

  5. Towards Next Generation Rubrics: An Automated Assignment Feedback System

    Directory of Open Access Journals (Sweden)

    Nilupulee Nathawitharana

    2017-11-01

    Full Text Available As the use of blended learning environments and digital technologies become integrated into the higher education sector, rich technologies such as analytics have shown promise in facilitating teaching and learning. One popular application of analytics is Automated Writing Evaluation (AWE systems. Such systems can be used in a formative way; for example, by providing students with feedback on digitally submitted assignments. This paper presents work on the development of an AWE software tool for an Australian university using advanced text analytics techniques. The tool was designed to provide students with timely feedback on their initial assignment drafts, for revision and further improvement. Moreover, it could also assist academics in better understanding students’ assignment performance so as to inform future teaching activities. The paper provides details on the methodology used for development of the software, and presents the results obtained from the analysis of text-based assignments submitted in two subjects. The results are discussed, highlighting how the tool can provide practical value, followed by insights into existing challenges and possible future directions.

    Science.gov (United States)

    Wen, Zhi; Pollock, Kenneth; Nichols, James; Waser, Peter

    2011-01-01

    Ecologists applying capture-recapture models to animal populations sometimes have access to additional information about individuals' populations of origin (e.g., information about genetics, stable isotopes, etc.). Tests that assign an individual's genotype to its most likely source population are increasingly used. Here we show how to augment a superpopulation capture-recapture model with such information. We consider a single superpopulation model without age structure, and split each entry probability into separate components due to births in situ and immigration. We show that it is possible to estimate these two probabilities separately. We first consider the case of perfect information about population of origin, where we can distinguish individuals born in situ from immigrants with certainty. Then we consider the more realistic case of imperfect information, where we use genetic or other information to assign probabilities to each individual's origin as in situ or outside the population. We use a resampling approach to impute the true population of origin from imperfect assignment information. The integration of data on population of origin with capture-recapture data allows us to determine the contributions of immigration and in situ reproduction to the growth of the population, an issue of importance to ecologists. We illustrate our new models with capture-recapture and genetic assignment data from a population of banner-tailed kangaroo rats Dipodomys spectabilis in Arizona.

  19. Privacy-Preserving Task Assignment in Spatial Crowdsourcing

    KAUST Repository

    Liu, An

    2017-09-20

    With the progress of mobile devices and wireless networks, spatial crowdsourcing (SC) is emerging as a promising approach for problem solving. In SC, spatial tasks are assigned to and performed by a set of human workers. To enable effective task assignment, however, both workers and task requesters are required to disclose their locations to untrusted SC systems. In this paper, we study the problem of assigning workers to tasks in a way that location privacy for both workers and task requesters is preserved. We first combine the Paillier cryptosystem with Yao’s garbled circuits to construct a secure protocol that assigns the nearest worker to a task. Considering that this protocol cannot scale to a large number of workers, we then make use of Geohash, a hierarchical spatial index to design a more efficient protocol that can securely find approximate nearest workers. We theoretically show that these two protocols are secure against semi-honest adversaries. Through extensive experiments on two real-world datasets, we demonstrate the efficiency and effectiveness of our protocols.

  7. Unusual spine anatomy contributing to wrong level spine surgery: a case report and recommendations for decreasing the risk of preventable 'never events'

    Directory of Open Access Journals (Sweden)

    Lindley Emily M

    2011-12-01

    Full Text Available Abstract Background Wrong site surgery is one of five surgical "Never Events," which include performing surgery on the incorrect side or incorrect site, performing the wrong procedure, performing surgery on the wrong patient, unintended retention of a foreign object in a patient, and intraoperative/immediate postoperative death in an ASA Class I patient. In the spine, wrong site surgery occurs when a procedure is performed on an unintended vertebral level. Despite the efforts of national safety protocols, literature suggests that the risk for wrong level spine surgery remains problematic. Case Presentation A 34-year-old male was referred to us to evaluate his persistent thoracic pain following right-sided microdiscectomy at T7-8 at an outside institution. Postoperative imaging showed the continued presence of a herniated disc at T7-8 and evidence of a microdiscectomy at the level immediately above. The possibility that wrong level surgery had occurred was discussed with the patient and revision surgery was planned. During surgery, the site of the previous laminectomy was clearly visualized; however, we also experienced confusion when verifying the level of the previous surgery. We ultimately used the previous laminectomy site as a landmark for identifying and treating the correct pathologic level. Postoperative consultation with Musculoskeletal Radiology revealed the patient had two abnormalities in his spinal anatomy that made intraoperative counting of levels inaccurate, including a pair of cervical ribs at C7 and the absence of a pair of thoracic ribs. Conclusion This case highlights the importance of strict adherence to a preoperative method of vertebral labeling that focuses on the landmarks used to label a pathologic disc space, rather than simply relying on the reference to a particular level. That is, by designating the pathological level as the disc space associated with the fourth rib up from the last rib-bearing vertebrae, rather than

  8. DNA evidence: wrong answers or wrong questions?

    Much of the controversy over DNA evidence is due to the way in which forensic scientific evidence has classically been presented. The orthodox approach is to consider whether two samples match according to a predetermined criterion. If they do, the fact of match is reported along with an estimate of the frequency of the characteristics. This method fails to address the questions raised in court cases, diverts argument into irrelevancies and stultifies research. Presentation of evidence in the form of likelihood ratios, on the other hand, forces the witness to answer the questions the court is interested in and makes apparent lines of research required to increase our understanding.

    2008-11-01

    Passive Optical Network (PON) system with characters of low-cost and high-efficiency has become a promising solution for access network in relieving the bandwidth bottleneck problem. PON system can provide high-speed optical subscriber networks with broad bandwidth and long distance transmission. In current telecommunication carriers' PON system, different service has its given priority which is configured by carriers based on common requirements. However, different users have their own requirement and inflexibility of the given default service priority causes users' inconvenience and frustration. In this paper, we propose a novel method of user controlled Port-IDentifier (Port-ID) assignment in a Gigabit-capable PON (GPON) system. This method provides users a more individualized priority determination mechanism for end users through assigning a multi-level Port-ID to different service. Then users can manage their own bandwidth based on their requirements for different service and carriers can provide a flexible service management mechanism.

  11. Using a digital storytelling assignment to teach public health advocacy.

    2017-10-29

    The need and expectation for advocacy is central to public health nursing practice. Advocacy efforts that effectively call attention to population health threats and promote the well-being of communities rely on strategies that deliver influential messaging. The digital story is a lay method to capture meaningful, impactful stories that can be used to advocate for public health concerns. Readily available, user-friendly digital technologies allow engagement in digital media production to create digital stories. This paper describes how digital story making can be utilized as an academic assignment to teach public health advocacy within an undergraduate nursing curriculum. Providing nursing students this artistic outlet can facilitate meeting academic learning goals, while also equipping them with creative skills that can be applied in future professional practice. Nursing educators can take advantage of institutional resources and campus culture to support the use of novel digital media assignments that facilitate application of advocacy concepts. © 2017 Wiley Periodicals, Inc.

  12. A tracked approach for automated NMR assignments in proteins (TATAPRO)

    2000-06-15

    A novel automated approach for the sequence specific NMR assignments of {sup 1}H{sup N}, {sup 13}C{sup {alpha}}, {sup 13}C{sup {beta}}, {sup 13}C'/{sup 1}H{sup {alpha}} and {sup 15}N spins in proteins, using triple resonance experimental data, is presented. The algorithm, TATAPRO (Tracked AuTomated Assignments in Proteins) utilizes the protein primary sequence and peak lists from a set of triple resonance spectra which correlate {sup 1}H{sup N} and {sup 15}N chemical shifts with those of {sup 13}C{sup {alpha}}, {sup 13}C{sup {beta}} and {sup 13}C'/{sup 1}H{sup {alpha}}. The information derived from such correlations is used to create a 'master{sub l}ist' consisting of all possible sets of {sup 1}H{sup N}{sub i}, {sup 15}N{sub i}, {sup 13}C{sup {alpha}}{sub i}, {sup 13}C{sup {beta}}{sub i}, {sup 13}C'{sub i}/{sup 1}H{sup {alpha}}{sub i}, {sup 13}C{sup {alpha}}{sub i-1}, {sup 13}C{sup {beta}}{sub i-1} and {sup 13}C'{sub i-1}/ {sup 1}H{sup {alpha}}{sub i-1} chemical shifts. On the basis of an extensive statistical analysis of {sup 13}C{sup {alpha}} and {sup 13}C{sup {beta}} chemical shift data of proteins derived from the BioMagResBank (BMRB), it is shown that the 20 amino acid residues can be grouped into eight distinct categories, each of which is assigned a unique two-digit code. Such a code is used to tag individual sets of chemical shifts in the master{sub l}ist and also to translate the protein primary sequence into an array called pps{sub a}rray. The program then uses the master{sub l}ist to search for neighbouring partners of a given amino acid residue along the polypeptide chain and sequentially assigns a maximum possible stretch of residues on either side. While doing so, each assigned residue is tracked in an array called assig{sub a}rray, with the two-digit code assigned earlier. The assig{sub a}rray is then mapped onto the pps{sub a}rray for sequence specific resonance assignment. The program has been tested using

  13. A neural network approach to dynamic task assignment of multirobots.

    Zhu, Anmin; Yang, Simon X

    2006-09-01

    In this paper, a neural network approach to task assignment, based on a self-organizing map (SOM), is proposed for a multirobot system in dynamic environments subject to uncertainties. It is capable of dynamically controlling a group of mobile robots to achieve multiple tasks at different locations, so that the desired number of robots will arrive at every target location from arbitrary initial locations. In the proposed approach, the robot motion planning is integrated with the task assignment, thus the robots start to move once the overall task is given. The robot navigation can be dynamically adjusted to guarantee that each target location has the desired number of robots, even under uncertainties such as when some robots break down. The proposed approach is capable of dealing with changing environments. The effectiveness and efficiency of the proposed approach are demonstrated by simulation studies.

    2008-01-01

    Supporting services play an important role in health care institutions such as hospitals. This paper presents an application of operations research model for optimal allocation of workers among supporting services in a public hospital. The services include logistics, inventory management, financial management, operations management, medical analysis, etc. The optimality criterion of the problem is to minimize operations costs of supporting services subject to some specific constraints. The constraints represent specific conditions for resource allocation in a hospital. The overall problem is formulated as an integer program in the literature known as the assignment problem, where the decision variables represent the assignment of people to various jobs. The results of some computational experiments modeled on a real data from a selected Polish hospital are reported.

    The average American adult reads at the 8th grade level while most written health information materials, including medication guides, are written at the 12th grade level. To assist students with health literacy-sensitive communication, pharmacy schools should incorporate educational activities addressing health literacy competencies. The objectives of this study were to evaluate the impact of a health literacy assignment on student pharmacists' perceptions of: 1) learning about health literacy; 2) ability to write health literacy level-appropriate patient education material; and 3) the use of these skills in future pharmacy practice. Third professional year student pharmacists were asked to rewrite a patient medication information sheet at the 5th grade reading level, altering it from the 12th grade level. Following assignment completion, students responded to a 4-item open-ended questionnaire on what they learned from the activity, what information components were the most difficult to rewrite and reason for the difficulty, key strategies to accomplish the assignment, and their perception of the impact this assignment had on their future practice. Content analysis of the reflections was performed using QSR NVivo to identify themes grounded in the students' responses. Reflections were completed in 2009 (n = 159) and 2010 (n = 144), for a total of 303 completed reflections. Predominant themes included greater understanding about the challenges, importance, and methods of health literacy level-appropriate communication and greater awareness of the role of pharmacists in presenting information clearly to patients. Students indicated the activity increased their understanding of the complexity of patient information, the educational needs of patients, and the importance of providing information that is understandable. Student pharmacists learned methods of effective communication with patients and should be better prepared to communicate in a health literacy

    This paper shows that rotation programs can be an effective response to concerns of employee budget padding. Rotation programs naturally create a "portfolio" of assignments for each manager, and the resulting diversification can reduce the downside of resource rationing. In particular, the production versus rents trade-off linked with adverse selection problems can be more efficiently carried out when the firm faces two managers with average information advantages, rather than one with a larg...

    2017-01-01

    Reducing the number of laboratory animals used and refining experimental procedures to enhance animal welfare are fundamental questions to be considered in connection with animal experimentation. Here, we explored the use of cardinal ethical weights for clinical signs and symptoms in rodents by conducting trade-off interviews with members of Swedish Animal Ethics Committees in order to derive such weights for nine typical clinical signs of toxicity. The participants interviewed represent researchers, politically nominated political nominees and representatives of animal welfare organizations. We observed no statistically significant differences between these groups with respect to the magnitude of the ethical weights assigned, though the political nominees tended to assign lower weights. Overall, hunched posture was considered the most severe clinical sign and body weight loss the least severe. The ethical weights assigned varied considerably between individuals, from zero to infinite value, indicating discrepancies in prioritization of reduction and refinement. Cardinal ethical weights may be utilized to include both animal welfare refinement and reduction of animal use in designing as well as in retrospective assessment of animal experiments. Such weights may also be used to estimate ethical costs of animal experiments.

    2014-11-01

    In engineering courses with very specific learning objectives, such as fluid mechanics and thermodynamics, it is conventional to reinforce concepts and principles with problem-solving assignments and to measure success in problem solving as an indicator of student achievement. While the modern-day ease of copying and searching for online solutions can undermine the value of traditional assignments, web-based technologies also provide opportunities to generate individualized well-posed problems with an infinite number of different combinations of initial/final/boundary conditions, so that the probability of any two students being assigned identical problems in a course is vanishingly small. Such problems can be designed and programmed to be: single or multiple-step, self-grading, allow students single or multiple attempts; provide feedback when incorrect; selectable according to difficulty; incorporated within gaming packages; etc. In this talk, we discuss the use of a homework/exam generating program of this kind in a single-semester course, within a web-based client-server system that ensures secure operation.

  8. Inspection of Forrestal parking permit allocation and assignments

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-16

    The purpose of this inspection was to review the process cr allocating and assigning parking permits at the Forrestal building. Specifically, we sought to determine the roles and responsibilities of Department of Energy (DOE) officials involved in the administration of the Forrestal parking permit process during the period June 1, 1991 to February 1, 1992. We also sought to determine if the allocation and assignment of Forrestal building parking spaces was implemented in accordance with Federal and DOE requirements. For our review, we interviewed the Headquarters officials involved in the administration of the parking permit allocation and assignment process. We also reviewed parking permit files and associated documentation for the period June 1, 1991 through February 1, 1992. In addition, we conducted a limited sampling of parking permits that were revoked during July and August 1991 to assess if they were processed in compliance with applicable regulations. We found no evidence that the actions by the Special Assistant to the Secretary (White House Liaison) and the other members of the parking committee regarding the issuance and revocation of parking permits were for any reason other than a desire to ensure that only individuals having a legitimate basis for a parking permit were issued a permit. However, we found that decisions by the parking committee regarding revocation of permits and appeals of revocation decisions were not always documented, nor were there written guidelines or procedures to govern the activities of the committee. In our view, the lack of written guidelines and procedures resulted in the use of invalidated personal knowledge by the parking committee in making decisions involving the revocation of parking permits and led to inconsistencies in the notification of individuals about the associated appeal process.

    Body motion delivers a wealth of socially relevant information. Yet display inversion severely impedes biological motion (BM) processing. It is largely unknown how the brain circuits for BM are affected by display inversion. As upright and upside-down point-light BM displays are similar, we addressed this issue by using ultrahigh field functional MRI at 9.4 T providing for high sensitivity and spatial resolution. Whole-brain analysis along with exploration of the temporal dynamics of the blood-oxygen-level-dependent response reveals that in the left hemisphere, inverted BM activates anterior networks likely engaged in decision making and cognitive control, whereas readily recognizable upright BM activates posterior areas solely. In the right hemisphere, multiple networks are activated in response to upright BM as compared with scarce activation to inversion. With identical visual input with display inversion, a large-scale network in the right hemisphere is detected in perceivers who do not constantly interpret displays as shown the "wrong way up." For the first time, we uncover (1) (multi)functional involvement of each region in the networks underpinning BM processing and (2) large-scale ensembles of regions playing in unison with distinct temporal dynamics. The outcome sheds light on the neural circuits underlying BM processing as an essential part of the social brain. © The Author 2017. Published by Oxford University Press. All rights reserved.

  10. DNA barcode data accurately assign higher spider taxa

    Directory of Open Access Journals (Sweden)

    Jonathan A. Coddington

    2016-07-01

    Full Text Available The use of unique DNA sequences as a method for taxonomic identification is no longer fundamentally controversial, even though debate continues on the best markers, methods, and technology to use. Although both existing databanks such as GenBank and BOLD, as well as reference taxonomies, are imperfect, in best case scenarios “barcodes” (whether single or multiple, organelle or nuclear, loci clearly are an increasingly fast and inexpensive method of identification, especially as compared to manual identification of unknowns by increasingly rare expert taxonomists. Because most species on Earth are undescribed, a complete reference database at the species level is impractical in the near term. The question therefore arises whether unidentified species can, using DNA barcodes, be accurately assigned to more inclusive groups such as genera and families—taxonomic ranks of putatively monophyletic groups for which the global inventory is more complete and stable. We used a carefully chosen test library of CO1 sequences from 49 families, 313 genera, and 816 species of spiders to assess the accuracy of genus and family-level assignment. We used BLAST queries of each sequence against the entire library and got the top ten hits. The percent sequence identity was reported from these hits (PIdent, range 75–100%. Accurate assignment of higher taxa (PIdent above which errors totaled less than 5% occurred for genera at PIdent values >95 and families at PIdent values ≥ 91, suggesting these as heuristic thresholds for accurate generic and familial identifications in spiders. Accuracy of identification increases with numbers of species/genus and genera/family in the library; above five genera per family and fifteen species per genus all higher taxon assignments were correct. We propose that using percent sequence identity between conventional barcode sequences may be a feasible and reasonably accurate method to identify animals to family/genus. However

    Full Text Available A CDMA-based mobile Ad Hoc networks face two main design challenges. One is to periodically update connectivity information, namely, neighboring nodes and the codes used by neighboring nodes. The other is to guarantee that there is no code collision in two hops' distance. This paper proposes an enhanced time-spread broadcasting schedule for connectivity information update. Based on the connectivity information, a code assignment and potential code collision resolution scheme to solve hidden/exposed nodes problem is proposed. Simulation results demonstrate the efficiency and effectiveness of the proposed schemes.

    The power of genetic algorithms (GAs) has been demonstrated for various domains of the computer science, including combinatorial optimization. In this paper, we propose a new conceptual modification of the genetic algorithm entitled a "restart-based genetic algorithm" (RGA). An effective implementation of RGA for a well-known combinatorial optimization problem, the quadratic assignment problem (QAP), is discussed. The results obtained from the computational experiments on the QAP instances from the publicly available library QAPLIB show excellent performance of RGA. This is especially true for the real-life like QAPs.

    Hussin, Mohamed Saifullah

    2017-11-01

    Since the formal introduction of metaheuristics, a huge number Quadratic Assignment Problem (QAP) instances have been introduced. Those instances however are loosely-structured, and therefore made it difficult to perform any systematic analysis. The QAPLIB for example, is a library that contains a huge number of QAP benchmark instances that consists of instances with different size and structure, but with a very limited availability for every instance type. This prevents researchers from performing organized study on those instances, such as parameter tuning and testing. In this paper, we will discuss several hard instances that have been introduced over the years, and algorithms that have been used for solving them.

  3. Neural correlates of temporal credit assignment in the parietal lobe.

    Directory of Open Access Journals (Sweden)

    Timothy M Gersch

    Full Text Available Empirical studies of decision making have typically assumed that value learning is governed by time, such that a reward prediction error arising at a specific time triggers temporally-discounted learning for all preceding actions. However, in natural behavior, goals must be acquired through multiple actions, and each action can have different significance for the final outcome. As is recognized in computational research, carrying out multi-step actions requires the use of credit assignment mechanisms that focus learning on specific steps, but little is known about the neural correlates of these mechanisms. To investigate this question we recorded neurons in the monkey lateral intraparietal area (LIP during a serial decision task where two consecutive eye movement decisions led to a final reward. The underlying decision trees were structured such that the two decisions had different relationships with the final reward, and the optimal strategy was to learn based on the final reward at one of the steps (the "F" step but ignore changes in this reward at the remaining step (the "I" step. In two distinct contexts, the F step was either the first or the second in the sequence, controlling for effects of temporal discounting. We show that LIP neurons had the strongest value learning and strongest post-decision responses during the transition after the F step regardless of the serial position of this step. Thus, the neurons encode correlates of temporal credit assignment mechanisms that allocate learning to specific steps independently of temporal discounting.

  4. Assignment of the stereochemistry of the isomers of IQNP

    The isomers of 1-azabicyclo[2.2.2]oct-3-yl {alpha}-hydroxy-{alpha}-(1-iodo-1-propen-3-yl)-{alpha}-phenylacetate (IQNP) are attractive for in vivo imaging of muscarinic receptors (mAChR). Although the stereocenter of the quinuclidinyl ring has been studied, the isomers of IQNP are oils and the configuration of the acetate center has not been elucidated. An improved synthesis of the acetate moiety (3) via a chiral intermediate has been developed and allows assignment of the configuration of the acetate. 1,3-dioxolan-4-one (1), (condensation of R- or S-mandelic acid and pivaldehyde) was alkylated with propargyl bromide, treated with base and esterified to afford R-(-)- or S-(+)-3. R- and S-3 were prepared in a 94:6 and 98:2 enantiomeric excess, respectively (HPLC analysis). R- and S-3 were utilized to synthesize the various isomers of IQNP. By comparing the optical rotation, HPLC and NMR of these isomers to those prepared by classical resolution allows the assignment of E-R, R-IQNP as the isomer demonstrating binding to M{sub 1} mAChR subtype and Z-R, R-IQNP as the isomer binding to M{sub 1} and M{sub 2}mAChR subtypes. This route also permits a simplified route for the preparation of the isomers of IQNP.

    In France, blood group determination requires the completion of two samples collected at two different times to detect identity mistake and "wrong blood in tube". The aims of the present study were: (1) to evaluate the compliance with guidelines and (2) to identify risk factors of non-compliance. Samples for ABO group determination collected between January 1st and December 15th, 2013 in the University hospital of Nîmes, France were analyzed. An ABO group determination demand was considered non-compliant if more than one tube arrived in the laboratory within ten minutes apart. Between May 1st and June 30th 2014, a self-administered questionnaire was offered to the nurses of the hospital on a random day for each service during this period. The aim was to validate the non-compliance criterion and the identification of risk factors using logistic regression. Among the 16,450 analyzed blood samples, the overall compliance rate was 65.1%. Lower compliance rates were found in the surgical services. Independent risk factors for wrong practice were work overload, surgical service and individual intermediate transfusion frequency. More than one third of ABO group determinations did not follow national recommendations, which induces a substantial risk of "wrong blood in tube" and group error. The study revealed major variations among hospital services. Identification of risk factors allows targeted corrective actions. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Starting from the hypothesis that the punctuation writing of whole and split words are areas in which secondary school students (regardless of age and school orientation achieved the weakest achievements an (exploratory research was conducted on a corpus of 3,135 written assignments written in the school year of 2010/11. The research sample was intentional, descriptive and analytical methods were used for the description and the analysis of the results. The results showed the following (1 secondary school students usually make mistakes in punctuation of written assignments - we recorded 4,487 errors in the use of signs to denote intonation and meaning of a text (errors of this type make 53.93% of the total number of spelling errors reported in the corpus of research; by frequency of errors the second are errors related to writing whole and split words (11.02%, the third error is in the use of the capital letter (9.34%; (2 most problems in orthography have second grade students, quantum of mistakes is almost the same with first graders and seniors, but in all grades the most frequent errors are in punctuation, writing of whole and split words and the use of capital letters; (3 Although school orientation affects the spelling skills of pupils, the weakest orthographic achievements are also recorded in punctuation, writing of whole and split words and capitalization, so those are areas that need to be thoroughly addressed in teaching and methodology literature. The results are, on the one hand, a picture of the current status of teaching orthography and grammar knowledge of secondary school students. On the other hand, the research results can be applied in all phases of methodical practical work in teaching orthography, the upgrading the

    The aim of this study was to examine if it is plausible to interpret the appearance of shame in a Swedish healthcare setting as a reaction to having one's honour wronged. Using a questionnaire, we studied answers from a sample of long-term sick-listed patients who had experienced negative encounters (n=1628) and of these 64% also felt wronged. We used feeling wronged to examine emotional reactions such as feeling ashamed and made the assumption that feeling shame could be associated with having one's honour wronged. In statistical analyses relative risks (RRs) were computed, adjusting for age, sex, disease-labelling, educational levels, as well as their 95% CI. Approximately half of those who had been wronged stated that they also felt shame and of those who felt shame, 93% (CI 91 to 95) felt that they had been wronged. The RR was 4.5 (CI 3.0 to 6.8) for shame when wronged. This can be compared with the other emotional reactions where the RRs were between 1.1 (CI 0.9 to 1.3)-1.4 (CI 1.2 to 1.7). We found no association between country of birth and feeling shame after having experienced negative encounters. We found that the RR of feeling shame when wronged was significantly higher compared with other feelings. Along with theoretical considerations, and the specific types of negative encounters associated with shame, the results indicate that our research hypothesis might be plausible. We think that the results deserve to be used as point of departure for future research.

    The absolute configurations of the separated enantiomers of fluralaner, a racemic animal health product used to prevent fleas and ticks, have been assigned using vibrational circular dichroism (VCD). The crystallographic structure of the active enantiomer (+)-fluralaner has previously been shown to have the (S) configuration using small molecule crystallography. We sought a faster analytical method to determine the absolute configuration of the separated enantiomers. When comparing the measured IR (infrared) and VCD spectra, it is apparent that the amide carbonyl groups appear in the IR but are nearly absent in the VCD. Computational work to calculate the VCD and IR using in vacuo models, implicit solvation, and explicitly solvated complexes has implicated conformational averaging of the carbonyl VCD intensities. © 2017 Wiley Periodicals, Inc.

  9. Consultant-Guided Search Algorithms for the Quadratic Assignment Problem

    Science.gov (United States)

    Iordache, Serban

    Consultant-Guided Search (CGS) is a recent swarm intelligence metaheuristic for combinatorial optimization problems, inspired by the way real people make decisions based on advice received from consultants. Until now, CGS has been successfully applied to the Traveling Salesman Problem. Because a good metaheuristic should be able to tackle efficiently a large variety of problems, it is important to see how CGS behaves when applied to other classes of problems. In this paper, we propose an algorithm for the Quadratic Assignment Problem (QAP), which hybridizes CGS with a local search procedure. Our experimental results show that CGS is able to compete in terms of solution quality with one of the best Ant Colony Optimization algorithms, the MAX-MIN Ant System.

    We provide a new automated statistical method for DNA barcoding based on a Bayesian phylogenetic analysis. The method is based on automated database sequence retrieval, alignment, and phylogenetic analysis using a custom-built program for Bayesian phylogenetic analysis. We show on real data...... that the method outperforms Blast searches as a measure of confidence and can help eliminate 80% of all false assignment based on best Blast hit. However, the most important advance of the method is that it provides statistically meaningful measures of confidence. We apply the method to a re......-analysis of previously published ancient DNA data and show that, with high statistical confidence, most of the published sequences are in fact of Neanderthal origin. However, there are several cases of chimeric sequences that are comprised of a combination of both Neanderthal and modern human DNA....

    Full Text Available This paper is aimed to develop the optimization model of time slot utilization for both runway and apron gate of airport system. The model considers the objectives of airline company to minimize flight-taxiing-time and waiting-time for both landing and take-off. The optimization makes use of Network Representation (NR in the form of two bipartite networks in order to transform the problem of runway and apron gate assignment into the network flow problem. Maximum Matching and Minimum Cost Flow on NR are the core of the model. An illustrative example is presented. The result shows that the model could increase both runway and apron gate capacities to as close as their theoretical capacities. Compared to the common practice which concerns only; the nearest available runway slot time, behind the scheduled time, and the nearest location of available gates to serve the flight, the model could reduce the total taxiing and waiting time.

    Full Text Available A reliable video communication system is proposed based on data partitioning feature of H.264/AVC, used to create a layered stream, and LT codes for erasure protection. The proposed scheme termed rate adaptive selective segment assignment (RASSA is an adaptive low-complexity solution to varying channel conditions. The comparison of the results of the proposed scheme is also provided for slice-partitioned H.264/AVC data. Simulation results show competitiveness of the proposed scheme compared to optimized unequal and equal error protection solutions. The simulation results also demonstrate that a high visual quality video transmission can be maintained despite the adverse effect of varying channel conditions and the number of decoding failures can be reduced.

    Full Text Available In this study, we are interested in the reusing activities of reverse logistics. We focus on the dynamic assignment of reusable containers problem (e.g. gas bottles, beverages, pallets, maritime containers, etc.. The objective is to minimize the collect, reloading, storage and redistribution operations costs over a fixed planning horizon taking into account the greenhouse gas emissions. We present a new generic Mixed Integer Programming (MIP model for the problem. The proposed model was solved using the IBM ILOG CPLEX optimization software; this method yield exact solutions, but it is very time consuming. So we adapted two hybrid approaches using a genetic algorithm to solve the problem at a reduced time (The second hybrid approach is enhanced with a local search procedure based on the Variable Neighborhood Search VNS. The numerical results show that both developed hybrid approaches generate high-quality solutions in a moderate computational time, especially the second hybrid method.

    2015-08-01

    Full Text Available Predicting student failure is an important task that can empower educators to counteract the factors that affect student performance. In this paper, a part of the bigger problem of predicting student failure is addressed: predicting the students that do not complete their assignment tasks. For solving this problem, real data collected by our university’s educational platform was used. Because the problem consisted of predicting one of three possible classes (multi-class classification, the appropriate algorithms and methods were selected. Several experiments were carried out to find the best approach for this prediction problem and the used data set. An approach of time segmentation is proposed in order to facilitate the prediction from early on. Methods that address the problems of high dimensionality and imbalanced data were also evaluated. The outcome of each approach is shown and compared in order to select the best performing classification algorithm for the problem at hand.

  17. THE EVOLUTION OF GARNISHMENT AND WAGE ASSIGNMENT LAW IN ILLINOIS

    Directory of Open Access Journals (Sweden)

    Bradley A. Hansen

    2014-07-01

    Full Text Available Recent research shows that, despite high interest rates, wage earners in the early twentieth century frequently obtained credit from retail shops, from loan sharks, and from the emerging formal consumer credit market. When wage earners defaulted, the options for collection available to their creditors were governed by state laws on garnishment and wage assignment. These important laws varied widely from state to state, and little is known about their origins or evolution. In Illinois, the law put significant restrictions on creditors in the late nineteenth century, but the restrictions were removed in the first quarter of the twentieth century. This article shows how this dramatic shift resulted from the interaction of legislative and judicial activity and was driven by both interest group politics and judicial action.

  18. Electre tri method used to storage location assignment into categories

    Marcele Elisa Fontana

    2013-08-01

    Full Text Available Day after day, the importance of a company having an efficient storage location assignment system increases. Moreover, since products have different warehouse costs and customers' requirements are also different, it is important to sort products in order to adopt strategies for inventory management that are appropriate for each product. However, adopting a policy for each product is not applicable in the real world. Therefore, companies usually categorize products into classes and thereafter adopt specific inventory management policies. Given this situation, this paper puts forward the arguments for adopting a multi-criteria method, Electre TRI, to sort products that both considers criteria relating to the characteristics of a product as to its physical location in the warehouse and the criteria that are important for inventory strategies, such as, for example, the profitability of each unit held in storage.

    Robertson, Lorayne; Hughes, Janette

    The authors review and evaluate a Teaching Methods course in Language and Literacy, one which focuses on multiple literacies, including digital literacy and critical literacy. The course is offered in a laptop-based university program. In this article, the authors outline the context of the multiple literacies course, its resources and assignments as well as their instructional goals. Their qualitative data sources include student-created digital artifacts such as digital literacy stories and digital book talks. The researchers draw from cross-program data based on hundreds of student reflections and one-on-one interviews. The authors conclude that there are indications from their data analysis that suggest that digital literacy supports the development of "transformative elements" that can extend beyond the teacher training program.

    2017-08-01

    The quadratic assignment problem is a combinatorial problem of deciding the placement of facilities in specified locations in such a way as to minimize a nonconvex objective function expressed in terms of flow between facilities, and distance between location. Due to the non-convexity nature of the problem, therefore to get a `good' starting point is necessary in order to obtain a better optimal solution. In this paper we propose a combined strategy (random point strategy to get initial starting point and then use forward exchange strategy and backward exchange strategy to get `optimal' solution). As a computational experience we've solved the problem of Esc 16b, Esc 16c and Esc 16h from QAPLIB. Finally, we present a comparative study between Combined Strategy and Data -Guided Lexisearch Algorithm. The computational study shows the effectiveness of our proposed combined strategy.

    Full Text Available The Fleet Assignment Problem (FAP of aircraft scheduling in airlines is studied, and the optimization model of FAP is proposed. The objective function of this model is revenue maximization, and it considers comprehensively the difference of scheduled flights and aircraft models in flight areas and mean passenger flows. In order to solve the model, a self-adapting genetic algorithm is supposed to solve the model, which uses natural number coding, adjusts dynamically crossover and mutation operator probability, and adopts intelligent heuristic adjusting to quicken optimization pace. The simulation with production data of an airline shows that the model and algorithms suggested in this paper are feasible and have a good application value.

    2015-05-01

    With 23 percent of all births taking place at home, The Netherlands have the highest rate of home births in the world. Also if the birth did not take place at home, it is not unusual for the mother and child to be out of hospital in a few hours after the baby was born. The explanation for both is the very well organised maternity care system. However, getting the right maternity care nurse available on time introduces a complex planning issue that can be recognized as a Stochastic Assignment Problem. In this paper an expert rule based approach is combined with scenario analysis to support the planner of the maternity care agency in his work.

    2008-04-01

    In this paper, both Pareto game theory and learning theory algorithms are utilized in a resource management module for a practical missile interception system. The resource management module will determine how many and which antimissiles will be launched for interception. Such interception decisions are based on the number of invading missiles, availability of antimissiles, special capability of antimissiles, and realistic constraints on the movements of both invading missiles and antimissiles such as minimum turning radius, maximum velocity, fuel range, etc. Simulations demonstrate performance improvements when compared to existing strategies (i.e. random assignment), independent of guidance laws (i.e. Proportional Navigation (PN) or the Differential-Game-based Guidance Law (DGL) guidance laws) under end-game interception cases or midcourse interception situations.

    aleurone layer and 47 glycoproteins were identified. Sequence homology search against allergen database reveals that many glycoproteins identified from wheat and barley share similarity with known food allergens and may therefore be targets in search of novel allergens from wheat flour........ Glycosylation is one of the most common PTMs of protein that is involved in many physiological functions and biological pathways. The aim of this Ph.D. project is mainly to screen and identify N-glycosylated proteins from barley and wheat. A HILIC-based glycopeptide enrichment technqiue was first developed...... by supplementing cotton wool with ZIC-HILIC in a microcolumn (called ZIC-cotton). This approach reduced co-enrichment of non-glycosylated peptides and allowed glycoppeptide identification from large protein mixtures. It was applied for glycoprotein identification and glycosylation site assignment in wheat albumin...

  5. Personalization of health care in England: have the wrong lessons been drawn from the personal health budget pilots?

    Science.gov (United States)

    Slasberg, Colin; Watson, Nick; Beresford, Peter; Schofield, Peter

    2014-07-01

    The Government has introduced personal health budgets in England's National Health Service (NHS). A three-year programme of pilots has shown that personal health budgets have improved outcomes and are generally cost-effective. They are seen as a key step toward creating a personalized service. However, the Government is attributing the success of the pilots to entirely the wrong factors. It believes that a process similar to the one introduced in social care - where it is called self-directed support - based on the person being given a sum of money 'up-front' with which to plan their own care - is responsible for the better outcomes. However, this is not supported by the evidence from the pilots which points to quite different factors being at play. The consequences are potentially very serious. The success of the pilots will not be repeated in roll out. Further, there is the potential to greatly weaken the service by creating confused process and practice, and additional dysfunctional bureaucracy. The practice and process implications from a correct reading of the reasons for success within the pilots centre on replacing the consumerist concepts underpinning self-directed support with what we have called 'flexibility through partnership'. This will require freeing up the resource base as cash and creating a policy framework to enable decisions about how much resource each person should get within a cash-limited budget that will almost certainly be less than would be required to meet all assessed need. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    We studied by native ESI-MS the binding of various DNA-polymerase-derived peptides onto DNA-polymerase processivity rings from Escherichia coli, Pseudomonas aeruginosa, and Mycobacterium tuberculosis. These homodimeric rings present two equivalent specific binding sites, which leads to successive formation during a titration experiment of singly- and doubly occupied rings. By using the ESI-MS free-ring spectrum as a ruler, we derived by robust linear regression the fractions of the different ring species at each step of a titration experiment. These results led to accurate Kd values (from 0.03 to 0.5 μM) along with the probability of peptide loss due to gas phase dissociation (GPD). We show that this good quality is due to the increased information content of a titration experiment with a homodimer. Isothermal titration calorimetry (ITC) led with the same binding model to Kd(ITC) values systematically higher than their ESI-MS counterparts and, often, to poor fit of the ITC curves. A processing with two competing modes of binding on the same site requiring determination of two (Kd, ΔH) pairs greatly improved the fits and yielded a second Kd(ITC) close to Kd(ESI-MS). The striking features are: (1) ITC detected a minor binding mode (~20%) of 'low-affinity' that did not appear with ESI-MS; (2) the simplest processing of ITC data with only one (Kd, ΔH) pair led wrongly to the Kd of the low-affinity binding mode but to the ΔH of the high-affinity binding mode. Analogous misleading results might well exist in published data based on ITC experiments. Graphical Abstract ᅟ.

    Diagnostic and treatment delay in depression are due to physician and patient factors. Patients vary in awareness of their depressive symptoms and ability to bring depression-related concerns to medical attention. To inform interventions to improve recognition and management of depression in primary care by understanding patients' inner experiences prior to and during the process of seeking treatment. Focus groups, analyzed qualitatively. One hundred and sixteen adults (79% response) with personal or vicarious history of depression in Rochester NY, Austin TX and Sacramento CA. Neighborhood recruitment strategies achieved sociodemographic diversity. Open-ended questions developed by a multidisciplinary team and refined in three pilot focus groups explored participants' "lived experiences" of depression, depression-related beliefs, influences of significant others, and facilitators and barriers to care-seeking. Then, 12 focus groups stratified by gender and income were conducted, audio-recorded, and analyzed qualitatively using coding/editing methods. Participants described three stages leading to engaging in care for depression - "knowing" (recognizing that something was wrong), "naming" (finding words to describe their distress) and "explaining" (seeking meaningful attributions). "Knowing" is influenced by patient personality and social attitudes. "Naming" is affected by incongruity between the personal experience of depression and its narrow clinical conceptualizations, colloquial use of the word depression, and stigma. "Explaining" is influenced by the media, socialization processes and social relations. Physical/medical explanations can appear to facilitate care-seeking, but may also have detrimental consequences. Other explanations (characterological, situational) are common, and can serve to either enhance or reduce blame of oneself or others. To improve recognition of depression, primary care physicians should be alert to patients' ill-defined distress and

    1996-05-01

    When President Abraham Lincoln was shot in the back of the head at Ford's Theater in Washington, D.C., on April 14, 1865, he was immediately rendered unconscious and apneic. Doctor Charles A. Leale, an Army surgeon, who had special training in the care of brain injuries, rushed to Lincoln's assistance. When Doctor Leale probed the wound in Lincoln's thickened scalp, feeling for the bullet, he dislodged a blood clot, and Lincoln began to breathe again. However, Lincoln progressively deteriorated and died at 7:22 AM on April 15, 1865. During the postmortem examination of Lincoln's body, numerous secondary missiles of bone and metal were found in the track of pultaceous brain tissue, extending completely through the brain to the front of the skull. In February 1995, an article in a popular magazine alleged that Doctor Leale had caused further (fatal) damage to Lincoln's brain by thrusting his finger into the brain through the bullet hole. The article alleged (wrongly) that most bullet wounds of the brain incurred in Civil War times were not fatal. The following study demonstrates that it is impossible to introduce even the tip of the little finger through a hole in the skull resulting from a .41-caliber bullet fired from a derringer. In our study, a .41-caliber derringer was used to fire bullets into numerous fresh skulls; the bullet holes all had razor-sharp edges and were much too small to accommodate a fingertip. Thus, the allegation that President Lincoln's brain was damaged further because Doctor Leale thrust his finger through the bullet hole into the brain parenchyma is not valid. In this study, experimental data are presented to demonstrate the foregoing point. The wound made by John Wilkes Booth's derringer ball in Lincoln's brain was devastating; it was clearly the cause of his death. Good Samaritan surgeon Leale has been falsely accused of contributing to Lincoln's death.

  11. Automated Pre-processing for NMR Assignments with Reduced Tedium

    Energy Technology Data Exchange (ETDEWEB)

    2004-05-11

    An important rate-limiting step in the reasonance asignment process is accurate identification of resonance peaks in MNR spectra. NMR spectra are noisy. Hence, automatic peak-picking programs must navigate between the Scylla of reliable but incomplete picking, and the Charybdis of noisy but complete picking. Each of these extremes complicates the assignment process: incomplete peak-picking results in the loss of essential connectivities, while noisy picking conceals the true connectivities under a combinatiorial explosion of false positives. Intermediate processing can simplify the assignment process by preferentially removing false peaks from noisy peak lists. This is accomplished by requiring consensus between multiple NMR experiments, exploiting a priori information about NMR spectra, and drawing on empirical statistical distributions of chemical shift extracted from the BioMagResBank. Experienced NMR practitioners currently apply many of these techniques "by hand", which is tedious, and may appear arbitrary to the novice. To increase efficiency, we have created a systematic and automated approach to this process, known as APART. Automated pre-processing has three main advantages: reduced tedium, standardization, and pedagogy. In the hands of experienced spectroscopists, the main advantage is reduced tedium (a rapid increase in the ratio of true peaks to false peaks with minimal effort). When a project is passed from hand to hand, the main advantage is standardization. APART automatically documents the peak filtering process by archiving its original recommendations, the accompanying justifications, and whether a user accepted or overrode a given filtering recommendation. In the hands of a novice, this tool can reduce the stumbling block of learning to differentiate between real peaks and noise, by providing real-time examples of how such decisions are made.

  12. What's wrong with CYP?

    Science.gov (United States)

    Shelton, J D

    1991-01-01

    The weaknesses of using couple years protection (CYP) for assessing the effectiveness of various measures of family planning are discussed. Limitations had been recognized in the past but have been largely ignored in the present context. This has been due to the unavailability of local data, and other standardizations have been too cumbersome for practical use. The advantage of using CYP is that it allows for easy calculation of a level of contraceptive use without differentiation by method. This measure reflects to some extent, for instance, access to family planning services, and prevention of unwanted fertility. It also measures output, and provides program managers with a tool to adjust supply to demand. The weakness are categorized in terms of contraceptive failure rates, sporadic and infrequent use with secondary partners, wastage, substitution, differences in fecundity, local specificity, lack of a discount for time, ability to reach high priority or underserved clients, secondary effects, quality of care, and so on. These weaknesses broadly effect the relationship of CYP with fertility; it is possible that adjustments can be made to improve the measure. The deficiencies in accounting for hard to reach clients, in measuring the secondary effects in AIDs and STD prevention, and in measuring satisfaction and continuation or other facets of quality of care not be accounted for in CYP. This suggests that a comprehensive assessment must utilize a variety of indicators, such as a direct measure of contraceptive prevalence, the proportion of children born to high risk women, continuation rates, and qualitative measures of the impact of care. Improvement of CYP is suggested as an inexpensive solution. Local data should be used, since the average age at sterilization in a particular population impacts greatly on the actual CYP provided by sterilization in a specific program. Cookbook conversion factors should be revised so that condoms (100 per CYP) credit is reduced and IUDs (2.5 CYP per IUD) is increased; CYP factors need to be developed for Norplant and Lactational Amenorrhea Method (LAM). An effort by the AID Cooperating Agency Task Force on Performance Indicators is underway to address these issues, but in the meantime awareness of the issues is advised.

  3. Delay functions in trip assignment for transport planning process

    Science.gov (United States)

    Leong, Lee Vien

    2017-10-01

    In transportation planning process, volume-delay and turn-penalty functions are the functions needed in traffic assignment to determine travel time on road network links. Volume-delay function is the delay function describing speed-flow relationship while turn-penalty function is the delay function associated to making a turn at intersection. The volume-delay function used in this study is the revised Bureau of Public Roads (BPR) function with the constant parameters, α and β values of 0.8298 and 3.361 while the turn-penalty functions for signalized intersection were developed based on uniform, random and overflow delay models. Parameters such as green time, cycle time and saturation flow were used in the development of turn-penalty functions. In order to assess the accuracy of the delay functions, road network in areas of Nibong Tebal, Penang and Parit Buntar, Perak was developed and modelled using transportation demand forecasting software. In order to calibrate the models, phase times and traffic volumes at fourteen signalised intersections within the study area were collected during morning and evening peak hours. The prediction of assigned volumes using the revised BPR function and the developed turn-penalty functions show close agreement to actual recorded traffic volume with the lowest percentage of accuracy, 80.08% and the highest, 93.04% for the morning peak model. As for the evening peak model, they were 75.59% and 95.33% respectively for lowest and highest percentage of accuracy. As for the yield left-turn lanes, the lowest percentage of accuracy obtained for the morning and evening peak models were 60.94% and 69.74% respectively while the highest percentage of accuracy obtained for both models were 100%. Therefore, can be concluded that the development and utilisation of delay functions based on local road conditions are important as localised delay functions can produce better estimate of link travel times and hence better planning for future

    Full Text Available Students’ error analysis is very important for helping EFL teachers to develop their teaching materials, assessments and methods. However, it takes much time and effort from the teachers to do such an error analysis towards their students’ language. This study seeks to identify the common errors made by 1 class of 28 freshmen students studying English in their first semester in an IT university. The data is collected from their writing assignments for eight consecutive weeks. The errors found were classified into 24 types and the top ten most common errors committed by the students were article, preposition, spelling, word choice, subject-verb agreement, auxiliary verb, plural form, verb form, capital letter, and meaningless sentences. The findings about the students’ frequency of committing errors were, then, contrasted to their midterm test result and in order to find out the reasons behind the error recurrence; the students were given some questions to answer in a questionnaire format. Most of the students admitted that careless was the major reason for their errors and lack understanding came next. This study suggests EFL teachers to devote their time to continuously check the students’ language by giving corrections so that the students can learn from their errors and stop committing the same errors.

    Full Text Available Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1 is a unique paracaspase protein whose protease activity mediates oncogenic NF-κB signalling in activated B cell-like diffuse large B cell lymphomas (ABC-DLBCLs. ABC-DLBCLs are aggressive lymphomas with high resistance to current chemotherapies. Low survival rate among patients emphasizes the urgent need for alternative treatment options. The characterization of the MALT1 will be an essential tool for developing new target-directed drugs against MALT1 dependent disorders. As the first step in the atomic-level NMR studies of the system, here we report, the (15N/(13C/(1H backbone assignment of the apo form of the MALT1 paracaspase region together with the third immunoglobulin-like (Ig3 domain, 44 kDa, by high resolution NMR. In addition, the non-uniform sampling (NUS based targeted acquisition procedure is evaluated as a mean of decreasing acquisition and analysis time for larger proteins.

  8. Assigning the causative lightning to the whistlers observed on satellites

    2006-11-01

    Full Text Available We study the penetration of lightning induced whistler waves through the ionosphere by investigating the correspondence between the whistlers observed on the DEMETER and MAGION-5 satellites and the lightning discharges detected by the European lightning detection network EUCLID. We compute all the possible differences between the times when the whistlers were observed on the satellite and times when the lightning discharges were detected. We show that the occurrence histogram for these time differences exhibits a distinct peak for a particular characteristic time, corresponding to the sum of the propagation time and a possible small time shift between the absolute time assigned to the wave record and the clock of the lightning detection network. Knowing this characteristic time, we can search in the EUCLID database for locations, currents, and polarities of causative lightning discharges corresponding to the individual whistlers. We demonstrate that the area in the ionosphere through which the electromagnetic energy induced by a lightning discharge enters into the magnetosphere as whistler mode waves is up to several thousands of kilometres wide.

  9. Sensing Attribute Weights: A Novel Basic Belief Assignment Method

    2017-01-01

    Dempster–Shafer evidence theory is widely used in many soft sensors data fusion systems on account of its good performance for handling the uncertainty information of soft sensors. However, how to determine basic belief assignment (BBA) is still an open issue. The existing methods to determine BBA do not consider the reliability of each attribute; at the same time, they cannot effectively determine BBA in the open world. In this paper, based on attribute weights, a novel method to determine BBA is proposed not only in the closed world, but also in the open world. The Gaussian model of each attribute is built using the training samples firstly. Second, the similarity between the test sample and the attribute model is measured based on the Gaussian membership functions. Then, the attribute weights are generated using the overlap degree among the classes. Finally, BBA is determined according to the sensed attribute weights. Several examples with small datasets show the validity of the proposed method. PMID:28358325

    2009-11-12

    To implement a cooperative learning activity to engage students in analyzing tertiary drug information resources in a literature evaluation course. The class was divided into 4 sections to form expert groups and each group researched a different set of references using the jigsaw technique. Each member of each expert group was reassigned to a jigsaw group so that each new group was composed of 4 students from 4 different expert groups. The jigsaw groups met to discuss search strategies and rate the usefulness of the references. In addition to group-based learning, teaching methods included students' writing an independent research paper to enhance their abilities to search and analyze drug information resources. The assignment and final course grades improved after implementation of the activity. Students agreed that class discussions were a useful learning experience and 75% (77/102) said they would use the drug information references for other courses. The jigsaw technique was successful in engaging students in cooperative learning to improve critical thinking skills regarding drug information.

    2017-06-01

    Sequential multiple assignment randomization trial (SMART) is a powerful design to study Dynamic Treatment Regimes (DTRs) and allows causal comparisons of DTRs. To handle practical challenges of SMART, we propose a SMART with Enrichment (SMARTER) design, which performs stage-wise enrichment for SMART. SMARTER can improve design efficiency, shorten the recruitment period, and partially reduce trial duration to make SMART more practical with limited time and resource. Specifically, at each subsequent stage of a SMART, we enrich the study sample with new patients who have received previous stages' treatments in a naturalistic fashion without randomization, and only randomize them among the current stage treatment options. One extreme case of the SMARTER is to synthesize separate independent single-stage randomized trials with patients who have received previous stage treatments. We show data from SMARTER allows for unbiased estimation of DTRs as SMART does under certain assumptions. Furthermore, we show analytically that the efficiency gain of the new design over SMART can be significant especially when the dropout rate is high. Lastly, extensive simulation studies are performed to demonstrate performance of SMARTER design, and sample size estimation in a scenario informed by real data from a SMART study is presented. © 2016, The International Biometric Society.

  12. Stress Assignment in N+N Combinations in Arabic

    Directory of Open Access Journals (Sweden)

    Abdel Rahman Mitib Altakhaineh

    2017-09-01

    Full Text Available The validity of stress as a criterion to distinguish between compounds and phrases has been investigated in many languages, including English (see e.g. Lieber 2005: 376; Booij 2012: 84. However, the possibility of using stress as a criterion in this way has not been investigated for Arabic. Siloni (1997: 21 claims that in N+N combinations in Semitic languages, stress always falls on the second element. However, the results of a study using PRAAT reveal that, in Modern Standard Arabic (MSA and Jordanian Arabic (JA, stress plays no role in distinguishing between various N+N combinations, i.e. compounds and phrases, e.g.ˈmuʕallim lfiizyaaʔ ‘the physics teacher’ vs.ˈbayt lwalad ‘the boy’s house’, respectively. Analysis shows that the default position of stress in N+N combinations in MSA and JA is on the first element. There is only one systematic exception, which is phonetically conditioned: in N+N combinations with assimilated geminates on the word boundary, a secondary stress or perhaps double stress is assigned.

    The determination of the cellular lineage in acute leukemia is a crucial step in the diagnosis and the later therapeutic conduct. In Tunisia, emerging country, some cases of acute leukemias are still treated on the basis of an only cytologic study because of lack of cytometry. Our objective is to realize a confrontation between cytology and flow cytometry in the diagnosis of AL and to analyze discrepancies. The study concerns 100 cases of AL. A second double-blind examination of the bone marrow smears of acute leukemias is realized by two cytologists and confronted to immunophenotyping. In two cases of AML, flow cytometry reassigned lineage into T ALL and biphenotypic AL. In three cases of ALL the lineage was reassigned into undifferentiated acute leukemia (2 cases) and biphenotypic acute leukemia (1 case). Lineage was not established in four cases, immunophenotyping allowed the diagnosis of B ALL in 3 cases, and of biphenotypic acute leukemia in 1 case. In both cases of discrepant findings, flow cytometry allowed the diagnosis of biphenotypic acute leukemia in a case and of AML in the other one. The cytological study remains insufficient in the diagnosis of lineage even with experimented cytologists. Immunophenotyping is essential in lineage assignment and reassignment.

    Full Text Available Background: Quadratic assignment problem (QAP is one of the most interesting of combinatorial optimization. Was presented by Koopman and Beckamanna in 1957, as a mathematical model of the location of indivisible tasks. This problem belongs to the class NP-hard issues. This forces the application to the solution already approximate methods for tasks with a small size (over 30. Even though it is much harder than other combinatorial optimization problems, it enjoys wide interest because it models the important class of decision problems. Material and methods: The discussion was an artificial intelligence tool that allowed to solve the problem QAP, among others are: genetic algorithms, Tabu Search, Branch and Bound. Results and conclusions: QAP did not arise directly as a model for certain actions, but he found its application in many areas. Examples of applications of the problem is: arrangement of buildings on the campus of the university, layout design of electronic components in systems with large scale integration (VLSI, design a hospital, arrangement of keys on the keyboard.

  15. Personality Traits as Patterns of Meaning Assignment Tendencies.

    Science.gov (United States)

    Kreitler, Shulamith

    2017-03-20

    The purpose is to present a new conception about the nature of personality traits based on the Kreitler Meaning System. The major constructs of the meaning system are referent, meaning value, meaning unit, and meaning variables characterizing the meaning unit. The individual's meaning profile is the set of meaning variables the individual uses as assessed by the Test of Meanings. Personality traits are defined as patterns of meaning assignment tendencies. After introducing the meaning system, the article describes the new conception of personality traits and presents the example of extraversion. Correlation coefficients of four different extraversion scales with the meaning profiles are analyzed. The findings enable defining the meaning profile of extraversion and validating it in view of the information available about extraoversion. Implications of the new conception are providing insight into the structure, nature, and dynamics of a trait, a factor, or a cluster of traits; comparing traits; validating traits; describing interactions between traits; assessing traits by the Test of Meanings; assessing traits and anti-traits; identifying traits; classifying traits; describing traits in interaction with other tendencies; and applying interventions for modifying traits. Applications concerning attitudes, cognitive performance, emotions, defenses, coping, and psychopathology are presented. © 2017 Wiley Periodicals, Inc.

    Jimenez, Jesus A.; Quintana, Rolando

    2000-10-01

    The objective of this research was to develop a decision support system (DSS) to study the impact of introducing new equipment into a medical apparel plant from a maintenance organizational structure perspective. This system will enable the company to determine if their capacity is sufficient to meet current maintenance challenges. The DSS contains two database sets that describe equipment and maintenance resource profiles. The equipment profile specifies data such as mean time to failures, mean time to repairs, and minimum mechanic skill level required to fix each machine group. Similarly, maintenance-resource profile reports information about the mechanic staff, such as number and type of certifications received, education level, and experience. The DSS will then use this information to minimize machine downtime by assigning the highest skilled mechanics to machines with higher complexity and product value. A modified version of the simplex method, the transportation problem, was used to perform the optimization. The DSS was built using the Visual Basic for Applications (VBA) language contained in the Microsoft Excel environment. A case study was developed from current existing data. The analysis consisted of forty-two machine groups and six mechanic categories with ten skill levels. Results showed that only 56% of the mechanic workforce was utilized. Thus, the company had available resources for meeting future maintenance requirements.

  17. Cerebellar Synaptic Plasticity and the Credit Assignment Problem.

    Jörntell, Henrik

    2016-04-01

    The mechanism by which a learnt synaptic weight change can contribute to learning or adaptation of brain function is a type of credit assignment problem, which is a key issue for many parts of the brain. In the cerebellum, detailed knowledge not only of the local circuitry connectivity but also of the topography of different sources of afferent/external information makes this problem particularly tractable. In addition, multiple forms of synaptic plasticity and their general rules of induction have been identified. In this review, we will discuss the possible roles of synaptic and cellular plasticity at specific locations in contributing to behavioral changes. Focus will be on the parts of the cerebellum that are devoted to limb control, which constitute a large proportion of the cortex and where the knowledge of the external connectivity is particularly well known. From this perspective, a number of sites of synaptic plasticity appear to primarily have the function of balancing the overall level of activity in the cerebellar circuitry, whereas the locations at which synaptic plasticity leads to functional changes in terms of limb control are more limited. Specifically, the postsynaptic forms of long-term potentiation (LTP) and long-term depression (LTD) at the parallel fiber synapses made on interneurons and Purkinje cells, respectively, are the types of plasticity that mediate the widest associative capacity and the tightest link between the synaptic change and the external functions that are to be controlled.

    Surgical targeting of the incorrect vertebral level (wrong-level surgery) is among the more common wrong-site surgical errors, attributed primarily to the lack of uniquely identifiable radiographic landmarks in the mid-thoracic spine. The conventional localization method involves manual counting of vertebral bodies under fluoroscopy, is prone to human error and carries additional time and dose. We propose an image registration and visualization system (referred to as LevelCheck), for decision support in spine surgery by automatically labeling vertebral levels in fluoroscopy using a GPU-accelerated, intensity-based 3D-2D (namely CT-to-fluoroscopy) registration. A gradient information (GI) similarity metric and a CMA-ES optimizer were chosen due to their robustness and inherent suitability for parallelization. Simulation studies involved ten patient CT datasets from which 50 000 simulated fluoroscopic images were generated from C-arm poses selected to approximate the C-arm operator and positioning variability. Physical experiments used an anthropomorphic chest phantom imaged under real fluoroscopy. The registration accuracy was evaluated as the mean projection distance (mPD) between the estimated and true center of vertebral levels. Trials were defined as successful if the estimated position was within the projection of the vertebral body (namely mPD anatomy in fluoroscopy in near-real-time could be valuable in reducing the occurrence of wrong-site surgery while helping to reduce radiation exposure. The method is applicable beyond the specific case of vertebral labeling, since any structure defined in pre-operative (or intra-operative) CT or cone-beam CT can be automatically registered to the fluoroscopic scene.

  9. Can the surgical checklist reduce the risk of wrong site surgery in orthopaedics? - can the checklist help? Supporting evidence from analysis of a national patient incident reporting system

    Full Text Available Abstract Background Surgical procedures are now very common, with estimates ranging from 4% of the general population having an operation per annum in economically-developing countries; this rising to 8% in economically-developed countries. Whilst these surgical procedures typically result in considerable improvements to health outcomes, it is increasingly appreciated that surgery is a high risk industry. Tools developed in the aviation industry are beginning to be used to minimise the risk of errors in surgery. One such tool is the World Health Organization's (WHO surgery checklist. The National Patient Safety Agency (NPSA manages the largest database of patient safety incidents (PSIs in the world, already having received over three million reports of episodes of care that could or did result in iatrogenic harm. The aim of this study was to estimate how many incidents of wrong site surgery in orthopaedics that have been reported to the NPSA could have been prevented by the WHO surgical checklist. Methods The National Reporting and Learning Service (NRLS database was searched between 1st January 2008- 31st December 2008 to identify all incidents classified as wrong site surgery in orthopaedics. These incidents were broken down into the different types of wrong site surgery. A Likert-scale from 1-5 was used to assess the preventability of these cases if the checklist was used. Results 133/316 (42% incidents satisfied the inclusion criteria. A large proportion of cases, 183/316 were misclassified. Furthermore, there were fewer cases of actual harm [9% (12/133] versus 'near-misses' [121/133 (91%]. Subsequent analysis revealed a smaller proportion of 'near-misses' being prevented by the checklist than the proportion of incidents that resulted in actual harm; 18/121 [14.9% (95% CI 8.5 - 21.2%] versus 10/12 [83.3% (95%CI 62.2 - 104.4%] respectively. Summatively, the checklist could have been prevented 28/133 [21.1% (95%CI 14.1 - 28.0%] patient safety

    Committee membership in gastroenterology national societies is considered prestigious, opening the door for leadership roles and professional advancement. Some have hypothesized that women ask for leadership opportunities less frequently than men. Our aim was to examine the gender representation of requests for placement on an American Society for Gastrointestinal Endoscopy (ASGE) committee. We analyzed deidentified records of all requests for assignment to ASGE committees from 2011 to 2014, including applicant's gender, prior service to ASGE, year of application, and whether the applicant was appointed. The primary outcome was the proportion of requests from women compared with the overall ASGE female membership. There were 513 requests for ASGE committee appointments; 101 (20%) were from women, exceeding the active ASGE female membership (15%; P = .004). Overall, the total number of committee requests increased over time from 89 to 195 (P = .08); the proportion of requests from women remained stable at 16% to 21% (P = .51). Compared with men, women were significantly less likely to have had previous ASGE service (28% vs 42%; P = .01) and more likely to have a statement of endorsement from a mentor (33% vs 24%; P = .06). The rate of appointment to a committee was 47% (95% confidence interval [CI], 41-52) overall, 42% (95% CI, 37-48) for male applicants, and 65% (95% CI, 54-76) for female applicants. Female gender (odds ratio [OR] 2.6; 1.5-4.5), endorsement from a mentor (OR 3.4; 2.1-5.6), and prior ASGE service (OR 2.3; 1.5-3.5) predicted committee appointment. For ASGE committee appointments, it appears that women who make requests are successful in receiving these appointments. Future work should evaluate requests and appointments by gender among other gastroenterology societies and explore whether service translates into leadership opportunities for women.

  11. Neptune's Discovery: Le Verrier, Adams, and the Assignment of Credit

    Science.gov (United States)

    Sheehan, William

    2011-01-01

    As one of the most significant achievements of 19th century astronomy, the discovery of Neptune has been the subject of a vast literature. A large part of this literature--beginning with the period immediately after the optical discovery in Berlin--has been the obsession with assigning credit to the two men who attempted to calculate the planet's position (and initially this played out against the international rivalry between France and England). Le Verrier and Adams occupied much different positions in the Scientific Establishments of their respective countries; had markedly different personalities; and approached the investigation using different methods. A psychiatrist and historian of astronomy tries to provide some new contexts to the familiar story of the discovery of Neptune, and argues that the personalities of these two men played crucial roles in their approaches to the problem they set themselves and the way others reacted to their stimuli. Adams had features of high-functioning autism, while Le Verrier's domineering, obsessive, orderly personality--though it allowed him to be immensely productive--eventually led to serious difficulties with his peers (and an outright revolt). Though it took extraordinary smarts to calculate the position of Neptune, the discovery required social skills that these men lacked--and thus the process to discovery was more bumbling and adventitious than it might have been. The discovery of Neptune occurred at a moment when astronomy was changing from that of heroic individuals to team collaborations involving multiple experts, and remains an object lesson in the sociological aspects of scientific endeavor.

  12. Chemical shift assignments of calmodulin constructs with EF hand mutations.

    2016-04-01

    Calmodulin (CaM) is a ubiquitous cytosolic Ca(2+)-binding protein able to bind and regulate hundreds of different proteins. It consists of two globular domains joined by a flexible central linker region. Each one of these domains contains two EF hand pairs capable of binding to Ca(2+). Upon Ca(2+) binding CaM undergoes a conformational change exposing hydrophobic patches that interact with its intracellular target proteins. CaM is able to bind to target proteins in the Ca(2+)-replete and Ca(2+)-deplete forms. To study the Ca(2+)-dependent/independent properties of binding and activation of target proteins by CaM, CaM constructs with Ca(2+) binding disrupting mutations of Asp to Ala at position one of each EF hand have been used. One target protein of CaM is nitric oxide synthase, which catalyzes the production of nitric oxide. At elevated Ca(2+) concentrations, CaM binds to neuronal NOS and endothelial NOS, making them the Ca(2+)-dependent NOS enzymes. In contrast, inducible NOS is transcriptionally regulated in vivo and binds to CaM at basal levels of Ca(2+). Here we report the NMR backbone and sidechain resonance assignments of C-lobe Ca(2+)-replete and deplete CaM12, N-lobe Ca(2+)-replete and deplete CaM34, CaM1234 in the absence of Ca(2+) and N-lobe Ca(2+)-replete CaM34 with the iNOS CaM-binding domain peptide.

    2016-02-01

    This paper describes the compilation of a special edition of the AUSNUT2011-2013 food composition database that includes glycemic index (GI) values. A 6-step, systematic methodology was used to assign GI to 5644 foods included in AUSNUT2011-2013. A total of 1752 (31%) foods were assigned a GI of 0 owing to low carbohydrate content; 363 (6%) had a direct match in 1 of the 4 data tables used; 1738 (31%) were assigned the GI of a 'closely related' food item; 1526 (27%) were assigned the weighted mean GI of ingredients; 205 (4%) were assigned the median GI of their corresponding food subgroup; 49 (<1%) were assigned a GI of 0 because they were not a significant source of carbohydrate in typical diets; and 5 (<1%) were assigned a default GI. We propose that this database should be used for all future Australian GI research until a subsequent version/update is compiled.

  14. A Bayesian approach to estimating hidden variables as well as missing and wrong molecular interactions in ordinary differential equation-based mathematical models.

    Ordinary differential equations (ODEs) are a popular approach to quantitatively model molecular networks based on biological knowledge. However, such knowledge is typically restricted. Wrongly modelled biological mechanisms as well as relevant external influence factors that are not included into the model are likely to manifest in major discrepancies between model predictions and experimental data. Finding the exact reasons for such observed discrepancies can be quite challenging in practice. In order to address this issue, we suggest a Bayesian approach to estimate hidden influences in ODE-based models. The method can distinguish between exogenous and endogenous hidden influences. Thus, we can detect wrongly specified as well as missed molecular interactions in the model. We demonstrate the performance of our Bayesian dynamic elastic-net with several ordinary differential equation models from the literature, such as human JAK-STAT signalling, information processing at the erythropoietin receptor, isomerization of liquid α -Pinene, G protein cycling in yeast and UV-B triggered signalling in plants. Moreover, we investigate a set of commonly known network motifs and a gene-regulatory network. Altogether our method supports the modeller in an algorithmic manner to identify possible sources of errors in ODE-based models on the basis of experimental data. © 2017 The Author(s).

  1. Assignment of grouped exposure levels for trend estimation in a regression analysis of summarized data.

    Takahashi, Kunihiko; Tango, Toshiro

    2010-11-10

    For performing regression analysis of summarized response data containing grouped intervals of exposure, many researchers use pre-assigned doses such as the median values of each interval. However, the trend estimate is considerably sensitive to the choice of the assigned values. In this paper, we propose a method to assign the values to obtain a more accurate regression coefficient applying the likelihood approach. Numerical illustrations and comparisons through simulations showed that the proposed dose assignment can yield better estimates of trend in the regression analysis of two variants than that obtained by the conventional assignment methods such as those that use median values. In particular, for the data of a case-control study, the proposed dose improved the accuracy of the procedures such as that developed by Greenland and Longnecker (1992) compared with the conventional pre-assigned dose.

    2008-01-01

    The relationship between treatment outcome and the extent to which participants completed homework assignments was evaluated among 60 cocaine-dependent individuals assigned to cognitive–behavioral therapy (CBT). Homework was assigned in 72% of all sessions and initiated by participants in 48% of the sessions in which it was assigned. Completion of homework was unrelated to participants' baseline characteristics and several indicators of treatment compliance. Participants who completed more homework assignments demonstrated significantly greater increases in the quantity and quality of their coping skills and used significantly less cocaine during treatment and through a 1-year follow-up. These data suggest that the extent to which participants are willing to complete extrasession assignments may be an important mediator of response to CBT. PMID:16173864

    1989-07-11

    Proton NMR assignments have been made for 121 of the 124 residues of bovine pancreatic ribonuclease A (RNase A). During the first stage of assignment, COSY and relayed COSY data were used to identify 40 amino acid spin systems belonging to alanine, valine, threonine, isoleucine, and serine residues. Approximately 60 other NH-{alpha}CH-{beta}CH systems were also identified but not assigned to specific amino acid type. NOESY data then were used to connect sequentially neighboring spin systems; approximately 475 of the possible 700 resonances in RNase A were assigned in this way. The authors' assignments agree with those for 20 residues assigned previously. NOESY correlations were used to identify regular backbone structure elements in RNase A, which are very similar to those observed in X-ray crystallographic studies.

  4. Modelling the Preferences of Students for Alternative Assignment Designs Using the Discrete Choice Experiment Methodology

    Directory of Open Access Journals (Sweden)

    Brendan Kennelly

    2014-11-01

    Full Text Available This paper outlines how a discrete choice experiment (DCE can be used to learn more about how students are willing to trade off various features of assignments such as the nature and timing of feedback and the method used to submit assignments. A DCE identifies plausible levels of the key attributes of a good or service and then presents the respondent with alternative bundles of these attributes and their levels and asks the respondent to choose between particular bundles. We report results from a DCE we conducted with undergraduate business students regarding their preferences for assignment systems. We find that the most important features of assignments are how relevant the assignments are for exam preparation and the nature of the feedback that students receive. We also find that students generally prefer online to paper assignments. We argue that the DCE approach has a lot of potential in education research.

    This purpose of this study was to evaluate the effects of web-based homework assignments on student (a) achievement, (b) homework completion rates, (c) reflectivity and critical-thinking skills, (d) computer usage skills, and (e) attitudes toward science classes and homework. The specific data sources that were collected and analyzed during the investigation included (a) pretests, posttests, and post-posttests, (b) teacher-created classroom quizzes, (c) a student attitude survey, (d) a computer skills survey, (e) pre- and post-experimental focus group interviews, and (f) a survey of encountered computer problems. In addition to these data sources, all student assignments were coded and analyzed for reflective content and critical-thinking skills usage. Finally, student homework completion rates were monitored. The results indicated the following: (1) The online assignments were at least as effective as traditional assignments in terms of student achievement. (2) The online assignments required less time to complete than did traditional homework assignments. (3) The online assignments were rated highly by members of the experimental group. (4) The online assignments had no significant impact on the homework completion rates of students. (5) The online assignments had no significant impact on student computer skills. (6) The online assignments helped to facilitate the improvement of student attitudes toward the use of technology in science classes. (7) The online assignments facilitated increased student reflectivity. (8) The online assignments helped to improve the attitudes of some of the experimental students toward science and science classes. Since very little research exists concerning the effects of online instruction on high school students, future research should expand the time frame, sample size, and sample composition of this study in order to ensure that the results obtained can be applied to the general student population.

  9. Integer Linear Programming for Constrained Multi-Aspect Committee Review Assignment

    Karimzadehgan, Maryam; Zhai, ChengXiang

    2011-01-01

    Automatic review assignment can significantly improve the productivity of many people such as conference organizers, journal editors and grant administrators. A general setup of the review assignment problem involves assigning a set of reviewers on a committee to a set of documents to be reviewed under the constraint of review quota so that the reviewers assigned to a document can collectively cover multiple topic aspects of the document. No previous work has addressed such a setup of committee review assignments while also considering matching multiple aspects of topics and expertise. In this paper, we tackle the problem of committee review assignment with multi-aspect expertise matching by casting it as an integer linear programming problem. The proposed algorithm can naturally accommodate any probabilistic or deterministic method for modeling multiple aspects to automate committee review assignments. Evaluation using a multi-aspect review assignment test set constructed using ACM SIGIR publications shows that the proposed algorithm is effective and efficient for committee review assignments based on multi-aspect expertise matching.

    Full Text Available This study adopted a qualitative approach to explore how non-scientists and scientific experts consider meteorology and the role of meteorological scientists by investigating newspaper articles regarding the ‘wrong forecast’ in the 2009 Typhoon Morakot. The results showed that the news reports demarcate actors in the debate as non-scientists and scientific experts, with the policy-makers in the former group, and the meteorologists and professors in the latter. This research also found that the way media represents pinpoints the shortcomings in weather forecast on the one hand, and constructs the understanding of meteorology, meteorologists as well as non-scientists for the readers on the other. These findings led us to rethink the role media plays in weather forecast, and readers’ (including the aforementioned non-scientists’ and scientific experts’ expectations to media.

    Full Text Available Turkish English language teachers have a general affinity to mispronounce theword-final /ng/ sound combination as /ŋk/ form, but not in an /Iŋ/ form, which is theright case. This is a typical case of a fossilized pronunciation. The result of thearticulation is a bad sounding articulation that gives a serious hardship to the foreignlanguage teacher. It must be borne in mind that bad pronunciation impedes and obscuresintelligibility, accuracy, fluency, and automatic control of pronunciation in the targetlanguage. The fossilized pronunciation errors keep bothering the communicativefluency of the teacher trainees and novice foreign language teachers who are on the job.Since teaching foreign languages is a vocational job, developing a good intelligiblepronunciation skill is an integral part of the profession. In this study, a very commonand wrong articulation of /N/ phoneme as /Nk/ by Turkish English teachers will be triedto be rehabilitated by using the audioarticulation model.

  12. ATTRIBUTION OF CONDUCT TO A STATE-THE SUBJECTIVE ELEMENT OF THE INTERNATIONAL RESPONSIBILITY OT THE STATE FOR INTERNATIONALLY WRONGFUL ACTS

    Directory of Open Access Journals (Sweden)

    FELICIA MAXIM

    2012-05-01

    Full Text Available In order to establish responsibility of states for internationally wrongful act, two elements are identified. First, the conduct in question must be attributable to the State under international law. Secondly, for responsibility to attach to the act of the State, the conduct must constitute a breach of an international legal obligation in force for that State at that time. For particular conduct to be characterized as an internationally wrongful act, it must first be attributable to the State. The State is a real organized entity, a legal person with full authority to act under international law. But to recognize this is not to deny the elementary fact that the State cannot act of itself. States can act only by and through their agents and representatives. In determining what constitutes an organ of a State for the purposes of responsibility, the internal law and practice of each State are of prime importance. The structure of the State and the functions of its organs are not, in general, governed by international law. It is a matter for each State to decide how its administration is to be structured and which functions are to be assumed by government. But while the State remains free to determine its internal structure and functions through its own law and practice, international law has a distinct role. Conduct is thereby attributed to the State as a subject of international law and not as a subject of internal law. The State as a subject of international law is held responsible for the conduct of all the organs, instrumentalities and officials which form part of its organization and act in that capacity, whether or not they have separate legal personality under its internal law.

  13. On the wrong inference of long-range correlations in climate data; the case of the solar and volcanic forcing over the Tropical Pacific

    A substantial weakness of several climate studies on long-range dependence is the conclusion of long-term memory of the climate conditions, without considering it necessary to establish the power-law scaling and to reject a simple exponential decay of the autocorrelation function. We herewith show one paradigmatic case, where a strong long-range dependence could be wrongly inferred from incomplete data analysis. We firstly apply the DFA method on the solar and volcanic forcing time series over the tropical Pacific, during the past 1000 years and the results obtained show that a statistically significant straight line fit to the fluctuation function in a log-log representation is revealed with slope higher than 0.5, which wrongly may be assumed as an indication of persistent long-range correlations in the time series. We argue that the long-range dependence cannot be concluded just from this straight line fit, but it requires the fulfilment of the two additional prerequisites i.e. reject the exponential decay of the autocorrelation function and establish the power-law scaling. In fact, the investigation of the validity of these prerequisites showed that the DFA exponent higher than 0.5 does not justify the existence of persistent long-range correlations in the temporal evolution of the solar and volcanic forcing during last millennium. In other words, we show that empirical analyses, based on these two prerequisites must not be considered as panacea for a direct proof of scaling, but only as evidence that the scaling hypothesis is plausible. We also discuss the scaling behaviour of solar and volcanic forcing data based on the Haar tool, which recently proved its ability to reliably detect the existence of the scaling effect in climate series.

  16. Automated assignment of NMR chemical shifts based on a known structure and 4D spectra

    Apart from their central role during 3D structure determination of proteins the backbone chemical shift assignment is the basis for a number of applications, like chemical shift perturbation mapping and studies on the dynamics of proteins. This assignment is not a trivial task even if a 3D protein structure is known and needs almost as much effort as the assignment for structure prediction if performed manually. We present here a new algorithm based solely on 4D [{sup 1}H,{sup 15}N]-HSQC-NOESY-[{sup 1}H,{sup 15}N]-HSQC spectra which is able to assign a large percentage of chemical shifts (73–82 %) unambiguously, demonstrated with proteins up to a size of 250 residues. For the remaining residues, a small number of possible assignments is filtered out. This is done by comparing distances in the 3D structure to restraints obtained from the peak volumes in the 4D spectrum. Using dead-end elimination, assignments are removed in which at least one of the restraints is violated. Including additional information from chemical shift predictions, a complete unambiguous assignment was obtained for Ubiquitin and 95 % of the residues were correctly assigned in the 251 residue-long N-terminal domain of enzyme I. The program including source code is available at https://github.com/thomasexner/4Dassign https://github.com/thomasexner/4Dassign .

  19. Controversies of Sex Re-assignment in Genetic Males with Congenital Inadequacy of the Penis.

    Science.gov (United States)

    Raveenthiran, Venkatachalam

    2017-07-08

    Sex assignment in 46XY genetic male children with congenital inadequacy of the penis (CIP) is controversial. Traditionally, children with penile length less than 2 cm at birth are considered unsuitable to be raised as males. They are typically re-assigned to female-sex and feminizing genitoplasty is usually done in infancy. However, the concept of cerebral androgen imprinting has caused paradigm shift in the philosophy of sex re-assignment. Masculinization of the brain, rather than length of the penis, is the modern criterion of sex re-assignment in CIP. This review summarizes the current understanding of the complex issue. In 46XY children with CIP, male-sex assignment appears appropriate in non-hormonal conditions such as idiopathic micropenis, aphallia and exstrophy. Female-sex re-assignment appears acceptable in complete androgen insensitivity (CAIS), while partial androgen insensitivity syndrome (PAIS) patients are highly dissatisfied with the assignment of either sex. Children with 5-alpha reductase deficiency are likely to have spontaneous penile lengthening at puberty. Hence, they are better raised as males. Although female assignment is common in pure gonadal dysgenesis, long-term results are not known to justify the decision.

  1. Stereospecific assignment of the asparagine and glutamine sidechain amide protons in proteins from chemical shift analysis

    Energy Technology Data Exchange (ETDEWEB)

    Harsch, Tobias; Schneider, Philipp; Kieninger, Bärbel; Donaubauer, Harald; Kalbitzer, Hans Robert, E-mail: hans-robert.kalbitzer@biologie.uni-regensburg.de [University of Regensburg, Institute of Biophysics and Physical Biochemistry and Centre of Magnetic Resonance in Chemistry and Biomedicine (Germany)

    2017-02-15

    Side chain amide protons of asparagine and glutamine residues in random-coil peptides are characterized by large chemical shift differences and can be stereospecifically assigned on the basis of their chemical shift values only. The bimodal chemical shift distributions stored in the biological magnetic resonance data bank (BMRB) do not allow such an assignment. However, an analysis of the BMRB shows, that a substantial part of all stored stereospecific assignments is not correct. We show here that in most cases stereospecific assignment can also be done for folded proteins using an unbiased artificial chemical shift data base (UACSB). For a separation of the chemical shifts of the two amide resonance lines with differences ≥0.40 ppm for asparagine and differences ≥0.42 ppm for glutamine, the downfield shifted resonance lines can be assigned to H{sup δ21} and H{sup ε21}, respectively, at a confidence level >95%. A classifier derived from UASCB can also be used to correct the BMRB data. The program tool AssignmentChecker implemented in AUREMOL calculates the Bayesian probability for a given stereospecific assignment and automatically corrects the assignments for a given list of chemical shifts.

  17. A Comparative Analysis of Pair-work and Individual Assignments In two ELT Grammar Classes

    Directory of Open Access Journals (Sweden)

    Olcay Sert

    2005-10-01

    Full Text Available Assignments prepared in pair-work have long been evaluated to be more successful whencompared to individually prepared assignments in many respects in foreign language learningcontexts. However, there is not much research conducted to reveal the advantages of pair-work in preparing assignments and the linguistic characteristics of the finished texts. In this paper, depending upon an experimental study with the first year students in Department of EnglishLanguage Teaching at Hacettepe University, quality of pair-work assignments and the factors affecting the preparation process are discussed and compared to individual assignments. Results indicate a variety of advantages of student collaboration in preparing written work since outputsare far more grammatical, include less spelling mistakes, and indicate a higher level ofgrammatical awareness. Additionally, pair-work helps students build positive interpersonalrelationships and create a high level of academic solidarity and confidence.

  18. Optimal carrier frequency assignments for a two-carrier-level SCPS system

    Science.gov (United States)

    Vuong, X. T.; Forsey, R. J.

    A two-carrier-level SCPC system may occur in a star network where one master station (hub) with large G/T communicates with many remote stations with small G/T via one satellite transponder. By properly assigning the frequencies of carriers passing through the transponder, one can reduce and balance the relative intermodulation power levels falling into the SCPC channels. Through computer simulation, optimal carrier frequency assignments are found for four different criteria of optimality. The optimal assignments vary with respect to the difference in the two levels of carrier output power. All four criteria provide the conclusion that when the difference is around 3 dB, the assignment with small carriers stacked in the middle is best; and, when the difference is large (greater than 6 dB) the assignment with large carriers and small carriers alternated is best.

    Full Text Available Due to static traffic assignment has poor performance in reflecting actual case and dynamic traffic assignment may incurs excessive compute cost, method of multi-time dynamic traffic assignment combining static and dynamic traffic assignment balances factors of precision and cost effectively. A method based on Dial's logit algorithm is proposed in the article to solve the dynamic stochastic user equilibrium problem in dynamic traffic assignment. Before that, a fitting function that can proximately reflect overloaded traffic condition of link is proposed and used to give corresponding model. Numerical example is given to illustrate heuristic procedure of method and to compare results with one of same example solved by other literature's algorithm. Results show that method based on Dial's algorithm is preferable to algorithm from others.

  20. Resolution of redundant semantic type assignments for organic chemicals in the UMLS.

    Science.gov (United States)

    Morrey, C Paul; Chen, Ling; Halper, Michael; Perl, Yehoshua

    2011-07-01

    The Unified Medical Language System (UMLS) integrates terms from different sources into concepts and supplements these with the assignment of one or more high-level semantic types (STs) from its Semantic Network (SN). For a composite organic chemical concept, multiple assignments of organic chemical STs often serve to enumerate the types of the composite's underlying chemical constituents. This practice sometimes leads to the introduction of a forbidden redundant ST assignment, where both an ST and one of its descendants are assigned to the same concept. A methodology for resolving redundant ST assignments for organic chemicals, better capturing the essence of such composite chemicals than the typical omission of the more general ST, is presented. The typical SN resolution of a redundant ST assignment is to retain only the more specific ST assignment and omit the more general one. However, with organic chemicals, that is not always the correct strategy. A methodology for properly dealing with the redundancy based on the relative sizes of the chemical components is presented. It is more accurate to use the ST of the larger chemical component for capturing the category of the concept, even if that means using the more general ST. A sample of 254 chemical concepts having redundant ST assignments in older UMLS releases was audited to analyze the accuracy of current ST assignments. For 81 (32%) of them, our chemical analysis-based approach yielded a different recommendation from the UMLS (2009AA). New UMLS usage notes capturing rules of this methodology are proffered. Redundant ST assignments have typically arisen for organic composite chemical concepts. A methodology for dealing with this kind of erroneous configuration, capturing the proper category for a composite chemical, is presented and demonstrated. Copyright © 2011 Elsevier B.V.
