  12. Frequently asked questions about global modeling (United States)

    Letellier, Christophe; Aguirre, Luis A.; Freitas, U. S.


    When a global model is attempted from experimental data, some preprocessing might be required. Therefore it is only natural to wonder what kind of effects the preprocessing might have on the modeling procedure. This concern is manifested in the form of recurrent frequently asked questions, such as "how does the preprocessing affect the underlying dynamics?" This paper aims at providing answers to important questions related to (i) data interpolation, (ii) data smoothing, (iii) data-estimated derivatives, (iv) model structure selection, and (v) model validation. The answers provided will hopefully remove some of those doubts and one shall be more confident not only on global modeling but also on various data analyses which may be also dependent on data preprocessing.

Our intention is to give a simple introduction to the physics of gases that would be helpful for newcomers to the field of hypoxia research. We will provide background knowledge about questions often asked, but without straightforward answers. What is O2 concentration, and what is O2 partial pressure? What is normoxia, and what is hypoxia? How much O2 is experienced by a cell residing in a culture dish in vitro vs in a tissue in vivo? By the way, the O2 concentration in a normoxic incubator is 18.6%, rather than 20.9% or 20%, as commonly stated in research publications. And this is strictly only valid for incubators at sea level.

  18. Frequently asked questions about family medicine in India. (United States)

    Kumar, Raman


    Family medicine (FM) is an independent and distinct medical specialty in the developed countries such as USA, UK, Australia, and Canada since 1960s. FM teaching is imparted at undergraduate and postgraduate levels in countries such as Nepal, Pakistan, and Sri Lanka. Family practice is the practicing vocation of the majority doctors in India. The practitioners of FM include general practitioners, family physicians, FM specialists, and medical officers in the public sector. Medical students are largely unaware about FM career as this concept is not introduced at MBBS level. Faculty and senior doctors from other disciplines are also not able to answer the queries related to FM as they themselves also have gone through the same education system for last three decades, largely unexposed to the concept of academic family medicine. This article is a compilation of frequently asked questions, and their appropriate responses, presented here to dispel myths and misinformation about FM specialty. The answers are deliberated upon by Dr. Raman Kumar the founder president of the Academy of Family Physicians of India and the chief editor of the Journal of Family Medicine and Primary Care. This article was originally published as an interview in Docplexus, a popular online network and website for medical doctors in November 2015.

  1. Management of hyperthyroidism due to Graves' disease: frequently asked questions and answers (if any). (United States)

    Bartalena, L; Chiovato, L; Vitti, P


    Graves' disease is the most common cause of hyperthyroidism in iodine-replete areas. Although progress has been made in our understanding of the pathogenesis of the disease, no treatment targeting pathogenic mechanisms of the disease is presently available. Therapies for Graves' hyperthyroidism are largely imperfect because they are bound to either a high rate of relapsing hyperthyroidism (antithyroid drugs) or lifelong hypothyroidism (radioiodine treatment or thyroidectomy). Aim of the present article is to offer a practical guidance to the reader by providing evidence-based answers to frequently asked questions in clinical practice.

  4. High-sensitivity cardiac troponin assays: answers to frequently asked questions. (United States)

    Chenevier-Gobeaux, Camille; Bonnefoy-Cudraz, Éric; Charpentier, Sandrine; Dehoux, Monique; Lefevre, Guillaume; Meune, Christophe; Ray, Patrick


    Cardiac troponin (cTn) assays have quickly gained in analytical sensitivity to become what are termed 'high-sensitivity cardiac troponin' (hs-cTn) assays, bringing a flurry of dense yet incomplete literature data. The net result is that cTn assays are not yet standardized and there are still no consensus-built data on how to use and interpret cTn assay results. To address these issues, the authors take cues and clues from multiple disciplines to bring responses to frequently asked questions. In brief, the effective use of hs-cTn hinges on knowing: specific assay characteristics, particularly precision at the 99th percentile of a reference population; factors of variation at the 99th percentile value; and the high-individuality of hs-cTn assays, for which the notion of individual kinetics is more informative than straight reference to 'normal' values. The significance of patterns of change between two assay measurements has not yet been documented for every hs-cTn assay. Clinicians need to work hand-in-hand with medical biologists to better understand how to use hs-cTn assays in routine practice.

    CERN Multimedia

    CERN Bulletin


    Why have we tried so hard to find the Higgs particle? How does the Higgs mechanism work? What is the difference in physics between strong evidence and a discovery? Why do physicists speak in terms of "sigmas"? Find out here!   Why have we tried so hard to find the Higgs particle? Because it could be the answer to the question: how does Nature decide whether or not to assign mass to particles? All the fundamental particles making up matter – the electron, the quarks, etc. – have masses. Moreover, quantum physics requires that forces are also carried by particles. The W and Z particles that carry the weak force responsible for radioactivity must also have masses, whereas the photon, the carrier of the electromagnetic force, has no mass at all. This is the root of the “Higgs problem”: how to give masses to the fundamental particles and break the symmetry between the massive W and Z and the massless photon? Just assigning masses by hand...

  7. Survey questions about sleep duration: does asking separately about weekdays and weekends matter? (United States)

    Lauderdale, Diane S


    There is no standard way to ask about sleep duration in surveys, and little is known about the comparability of different questions. This article reports on a randomized survey experiment designed to test 1 type of variation: 1 question about usual sleep hours versus 2 questions separately asking about weekday and weekend sleep. Mean sleep duration was significantly shorter (7.03 hr vs. 7.28 hr) for the single question than a weighted average from 2 questions, and race and ethnicity contrasts differed by question format. Correlations between sleep duration and reported sleep need were significantly higher for the 2-question format. These results demonstrate that question wording can affect reported sleep duration in complicated ways, making it difficult to compare studies that use different questions.

  9. The effects of survey mode and asking about future intentions on self-reports of colorectal cancer screening. (United States)

    Beebe, Timothy J; Jenkins, Sarah M; Anderson, Kari J; Davern, Michael E; Rockwood, Todd H


    Colorectal cancer (CRC) screening rates are often ascertained via self-reports but can be subject to overreporting bias. Asking about intention to get screened before asking about past screening may minimize overreporting of cancer screening. In a statewide survey conducted from July through October of 2005, we embedded an experiment that tested the effect of question ordering (asking about future intention to get screened before or after asking about past screening; "future first" and "future second," respectively), crossed with survey mode (mail versus telephone), on CRC screening rates. Weighted analysis focused on 752 respondents who were ages 50 years or older. We found (a) that asking about future intentions to get screened before asking about past screening (future first) statistically significantly lowers reports of past CRC screening [70.9% future second versus 58.0% future first; odds ratio (OR), 1.83; 95% confidence interval (95% CI), 1.08-3.13]; (b) that there was no main effect of survey mode; and (c) that the effect of the ordering of the future intentions item varies by survey mode. In the mailed survey, the odds of reporting past CRC screening were almost thrice greater in the future second condition compared with the future first condition (72.4% versus 49.0%, respectively; OR, 2.74; 95% CI, 1.22-6.17). In the telephone condition, the odds of reporting were only 28% higher in the future second (69.5%) condition than in the future first condition (63.9%; OR, 1.28; 95% CI, 0.64-2.57). The results suggest that asking about future intentions to get screened before the actual behavior elicits lower, and arguably more truthful reports of CRC screening but mainly in mailed surveys.

  10. 'Asking the Right Question'. A Comparison of Two Approaches to Gathering Data on 'Herbals' Use in Survey Based Studies.

    Directory of Open Access Journals (Sweden)

    James S McLay

    Full Text Available Over the last decade academic interest in the prevalence and nature of herbal medicines use by pregnant women has increased significantly. Such data are usually collected by means of an administered questionnaire survey, however a key methodological limitation using this approach is the need to clearly define the scope of 'herbals' to be investigated. The majority of published studies in this area neither define 'herbals' nor provide a detailed checklist naming specific 'herbals' and CAM modalities, which limits inter-study comparison, generalisability and the potential for meta-analyses. The aim of this study was to compare the self-reported use of herbs, herbal medicines and herbal products using two different approaches implemented in succession.Cross-sectional questionnaire surveys of women attending for their mid-trimester scan or attending the postnatal unit following live birth at the Royal Aberdeen Maternity Hospital, North-East Scotland. The questionnaire utilised two approaches to collect data on 'herbals' use, a single closed yes/no answer to the question "have you used herbs, herbal medicines and herbal products in the last three months"; and a request to tick which of a list of 40 'herbals' they had used in the same time period.A total of 889 responses were obtained of which 4.3% (38 answered 'yes' to herbal use via the closed question. However, using the checklist 39% (350 of respondents reported the use of one or more specific 'herbals' (p<0.0001. The 312 respondents who reported 'no' to 'herbals' use via the closed question but "yes" via the checklist consumed a total of 20 different 'herbals' (median 1, interquartile range 1-2, range 1-6.This study demonstrates that the use of a single closed question asking about the use of 'herbals', as frequently reported in published studies, may not yield valid data resulting in a gross underestimation of actual use.

  14. Which long-term care residents should be asked to complete a customer satisfaction survey? (United States)

    Van De Water, Margaret S; Kutner, Michael; Parmelee, Patricia A; Johnson, Theodore


    (1) To compare staff members' opinions of long-term care (LTC) residents' ability to complete a customer satisfaction survey (CSS) with a measure of cognition (MDS-COGS) derived from Minimum Data Set data; and (2) to examine the association between CSS answer reliability and MDS-COGS score. Retrospective comparison of the staff's assessment and MDS-COGS score for each respondent, as well as a prospective comparison of MDS-COGS scores with reliability measures from repeated survey administration. A 100-bed Veterans Affairs (VA) nursing home. We administered a CSS designed by our VA network following an assigned protocol. We later calculated each respondent's MDS-COGS score (grouped into 4 categories) and compared it with the staff's opinion of whether that resident was "capable of responding" (yes/no) to a CSS. We subsequently modified the CSS for low reading level and low vision, and randomly selected 40 LTC residents for repeated survey administration (T1 and T2 1 week later). Test-retest reliability was estimated by examining the extent to which T1 and T2 answers agreed (agreed exactly; meaningfully agreed as defined by VA network personnel who designed the survey; or meaningfully agreed as decided by paper authors). Staff judged that 25 of 76 LTC residents were not and 51 of 76 were capable of responding to the CSS. In 82% of cases, MDS-COGS score category and staff opinion agreed ("no cognitive impairment"/"mild-moderate cognitive impairment" with "able to complete"; and "moderate-severe cognitive impairment"/"severe cognitive impairment" with "unable to complete"). Cohen's kappa was 0.57 with a P value of survey administration, 32 successfully completed surveys at T1 and T2. Higher MDS-COGS scores, suggesting greater cognitive impairment, were significantly associated with lower answer reliability. The answers given by LTC residents changed meaningfully (by network criteria) from T1 to T2 by 12%, 27%, and 28% across categories of no-to-mild cognitive

  8. [Adolescents ask physicians on the Internet: a one-year survey of adolescents' questions on health issues in an Internet forum]. (United States)

    Hardoff, Daniel; Friedman, Rina; Pilo, Nurit; Friedman, Fernando; Greilsammer, Daniel; Rigler, Shmuel


    During the past decade, the internet has become a major information resource in various domains of life and a communication venue among young people and adolescents who seek health information via the internet. Until now, the contents of Israeli adolescents' questions regarding health issues on internet sites have not been published. (1) A survey of the characteristics of adolescents who seek health information and their questions presented to the Ynet forum "The body during adolescence". In this forum physicians experienced in adolescent medicine respond to these questions and to comments of other forum participants. (2) Presentation of problematic issues in professionals' responses to health questions in the internet. Survey of a representative sample of contacts to the Ynet forum "The body during adolescence" during 2009 gathering information on gender and age of contacting person, parents' contacts, contacts' contents and physicians responses. A total of 412 contacts were surveyed, 210 (51%) females, aged 14-17 years--60%, 10-13 years--17% and 18-21 years 15%. Parents' questions appeared in 39 (9%) of contacts. Of all contacts, 44% related to sexuality issues and 17% related to self image and body composition. The physicians provided complete responses to 60% of the contacts, while in 40% the physician's responses included referral to clinical medical consultation. An internet health forum enables adolescents and parents to ask questions and raise doubts and anxieties regarding various health issues without the fear of being exposed and enables them to express their concerns face-to-face with a healthcare provider Sensitive issues regarding sexuality and self-image, which are not raised frequently during clinical encounters, are expressed and receive professional responses in the forum. Notwithstanding the significance of a rapid professional contribution, physicians responding to contacts in internet forums need to recognize the barrier related to professional

  9. [Utilization of antibiotics according to most frequent indications at Hungarian hospitals and results of surveys]. (United States)

    Ternák, G; Almási, I


    Antibiotic utilisation of 8 Hungarian hospitals was analyzed examining the case histories of patients who were discharged between January 1 and 31, 1995. Usage of antibiotics in the most frequent indications is reported in this paper. Majority of the prescriptions for the treatment of upper and lower respiratory tract infections were broad spectrum beta lactams. Higher rate of penicillin usage was found only in tonsillitis cases. Besides II. generation cephalosporins (22.7% of 730 prescriptions), beta-lactamase inhibitor + aminopenicillin combinations (13.4%) and III. generation cephalosporins (9.5%) considerable quantity of aminoglycosides (14.9%) and quinolones (9.5%) were found in pneumonia. Relatively high rate of aminoglycosides in the treatment of lower respiratory infections is inconsistent with therapeutic guidelines in force. Co-trimoxazol and quinolones were most frequently prescribed for the treatment of lower urinary tract infections. Traditional urodesinficients were on the first place only at one hospital. Treatment of frequently occurring nosocomial infections was compared with those of community acquired at the same site. There was not significant difference in the utilisation rates of the most of antibiotic groups regarding place of disease acquisition. 44% of the 1373 prescriptions for perioperative profilaxis was indicated for clean operations where benefit of antibiotic administration is questionable. Duration of antibiotic profilaxis was more than 48 hours in 59% of prescriptions. Drugs most frequently used for perioperative profilaxis were II. generation cephalosporins (23.7%), metronidazol (16.7%), aminoglycosides (9.6%) and III. generation cephalosporines (9.6%). The authors compare their results to the literature. They suggest the setting up of "infection control committees" to organise the antibiotic policies in hospitals.

    Substance use among teenage students and factors associated were investigated through a survey using a questionnaire adapted from the WHO's Program on Research and Reporting on the Epidemiology of Drug Dependence, additional questions on family factors and personal risks, and the Coopersmith Self-Esteem Inventory, adapted to Brazil. The target population consisted of 3891 10-22-year-old students from the city of Embu das Artes, São Paulo, Brazil. The prevalence of lifetime substance use was 26.7%. Most commonly used substances were energy drinks combined with alcohol (19%), solvents (11.2%) and marijuana (4.8%). Almost 60% of the students had already tried alcohol and 18.2% had tried tobacco. Factors associated to lifetime substance use were: lower self-esteem, going to nightclubs at least twice a week, use of alcohol, trying tobacco, bad relationship with the mother, permissive mothers, practicing sports as an obligation, working, and higher socioeconomic level. Concerning frequent/heavy substance use, chances were found to be higher among students who had use tobacco and alcohol, going to nightclubs at least twice a week, and those with lower self-esteem. Preventive actions concerning drug use should focus on avoiding the first experimentation, approaching family relationships, and improving students' self-esteem.

  13. Asking about Sex in General Health Surveys: Comparing the Methods and Findings of the 2010 Health Survey for England with Those of the Third National Survey of Sexual Attitudes and Lifestyles.

    Directory of Open Access Journals (Sweden)

    Philip Prah

    Full Text Available Including questions about sexual health in the annual Health Survey for England (HSE provides opportunities for regular measurement of key public health indicators, augmenting Britain's decennial National Survey of Sexual Attitudes and Lifestyles (Natsal. However, contextual and methodological differences may limit comparability of the findings. We examine the extent of these differences between HSE 2010 and Natsal-3 and investigate their impact on parameter estimates.Complex survey analyses of data from men and women in the 2010 HSE (n = 2,782 men and 3,588 women and Natsal-3 undertaken 2010-2012 (n = 4,882 men and 6,869 women aged 16-69y and resident in England, both using probability sampling, compared their characteristics, the amount of non-response to, and estimates from, sexual health questions. Both surveys used self-completion for the sexual behaviour questions but this was via computer-assisted self-interview (CASI in Natsal-3 and a pen-and-paper questionnaire in HSE 2010.The surveys achieved similar response rates, both around 60%, and demographic profiles largely consistent with the census, although HSE participants tended to be less educated, and reported worse general health, than Natsal-3 participants. Item non-response to the sexual health questions was typically higher in HSE 2010 (range: 9-18% relative to Natsal-3 (all <5%. Prevalence estimates for sexual risk behaviours and STI-related indicators were generally slightly lower in HSE 2010 than Natsal-3.While a relatively high response to sexual health questions in HSE 2010 demonstrates the feasibility of asking such questions in a general health survey, differences with Natsal-3 do exist. These are likely due to the HSE's context as a general health survey and methodological limitations such as its current use of pen-and-paper questionnaires. Methodological developments to the HSE should be considered so that its data can be interpreted in combination with those from dedicated

  14. Frequent Mental Distress, Chronic Conditions, and Adverse Health Behaviors in the Behavioral Risk Factor Surveillance Survey, Jordan, 2007

    Directory of Open Access Journals (Sweden)

    Mohannad Al-Nsour, MD, MSc


    Full Text Available Introduction Recent evidence indicates that chronic diseases and mental illness are associated. In the Middle Eastern country of Jordan, chronic diseases and frequent mental distress (FMD are increasing; however, the capacity for mental health care is limited. The objective of this study was to determine the association between FMD, chronic conditions, and adverse health behaviors in Jordan. Methods The third cycle of the Jordan Behavioral Risk Factor Surveillance Survey (2007 served as the data source for this study. The sample consisted of 3,612 noninstitutionalized Jordanian adults aged 18 years or older. Logistic regression was used to obtain odds ratios for the association between chronic conditions, health behaviors, and FMD adjusted for age, sex, marital status, education, income, and employment. Results In the adjusted models, people with hypertension (adjusted odds ratio [AOR], 2.0; 95% confidence interval [CI], 1.6–2.7, high cholesterol (AOR, 2.3; 95% CI, 1.6–3.2, diabetes (AOR, 1.6; 95% CI, 1.1–2.4, and asthma (AOR, 2.2; 95% CI, 1.5–3.1 and smokers (AOR, 1.5; 95% CI, 1.1–2.0 were more likely to have FMD than people without each of these conditions. Adults who reported vigorous physical activity were less likely to have FMD (AOR, 0.6; 95% CI, 0.4–0.9 than their less active counterparts. Conclusions In Jordan, FMD was associated with several chronic conditions. As a result, we suggest additional research to examine the complex relationship between FMD and chronic conditions. More doctors in the primary health care system should be trained in mental health.

  12. Frequent hospital admission of older people with chronic disease: a cross-sectional survey with telephone follow-up and data linkage

    Directory of Open Access Journals (Sweden)

    Longman Jo M


    Full Text Available Abstract Background The continued increase in hospital admissions is a significant and complex issue facing health services. There is little research exploring patient perspectives or examining individual admissions among patients with frequent admissions for chronic ambulatory care sensitive (ACS conditions. This paper aims to describe characteristics of older, rural patients frequently admitted with ACS conditions and identify factors associated with their admissions from the patient perspective. Methods Patients aged 65+ resident in North Coast NSW with three or more admissions for selected ACS chronic conditions within a 12 month period, were invited to participate in a postal survey and follow up telephone call. Survey and telephone data were linked to admission and health service program data. Descriptive statistics were generated for survey respondents; logistic regression models developed to compare characteristics of patients with 3 or with 4+ admissions; and comparisons made between survey respondents and non-respondents. Results Survey respondents (n=102 had a mean age of 77.1 years (range 66–95 years, and a mean of 4.1 admissions within 12 months; 49% had at least three chronic conditions; the majority had low socioeconomic status; one in five (22% reported some difficulty affording their medication; and 35% lived alone. The majority reported psychological distress with 31% having moderate or severe psychological distress. While all had a GP, only 38% reported having a written GP care plan. 22% of those who needed regular help with daily tasks did not have a close friend or relative who regularly cared for them. Factors independently associated with more frequent (n=4+ relative to less frequent (n=3 admissions included having congestive heart failure (p=0.003, higher social isolation scores (p=0.040 and higher Charlson Comorbidity Index scores (p=0.049.

  1. An internet-based survey of 96 German-speaking users of "bath salts": frequent complications, risky sexual behavior, violence, and delinquency. (United States)

    Schmoll, Sabrina; Romanek, Katrin; Stich, Raphael; Bekka, Elias; Stenzel, Jochen; Geith, Stefanie; Eyer, Florian; Rabe, Christian


    To define the demographics of German-speaking "bath salt" users. Prospective web-based survey of volunteer users of "bath salts". Subject recruitment/exclusion: Participation was solicited by posts in web forums frequented by users of synthetic cathinones. An invitation to participate was also disseminated via regional drug information centers. Responses were discarded if participants refused data analysis, provided incomplete surveys, were under 18 years of age (five cases), and in case of clearly improbable answers (i.e., two cases with profanity typed in free-form input fields). Overall 96 out of 180 participants provided complete questionnaires. These were further analyzed. 74% of respondents were male. 41% were under the age of 30 and a further 38% between 30 and 39 years old. Cathinones were used on more than 10 days in the preceding year by 62% of study subjects. The nasal and intravenous routes of administration were most often used. About 80% of respondents reported binge use. There were frequent co-administrations of opioids and opiates. The most common complication was prolonged confusion (47%). 16% had been involuntarily confined. One third had thoughts of violence and 16% acted on these thoughts either against themselves or others. About 44% reported high-risk sexual activity under the influence of cathinones. About 31% had driven or ridden a bike while intoxicated. About 6% had problems with law-enforcement for selling cathinones and 16% for crimes committed under the influence of cathinones. In conclusion, cathinone users are typically young males in their twenties and thirties. Most are experienced drug users, particularly of alcohol and opiates/opioids. The impact on society is tremendous as evidenced by high rates of self-reported violence, high-risk sexual activity, crimes, and traffic violations.

Results Most patients were males, mean age of 61 years, who reported experiencing at least one acute gout flare in the past 12 months, and 12.3% (n = 76 reported presence of tophi. Among the 27.7% (n = 172 of patients who were aware of their sUA levels, higher sUA was associated with more flares and tophi. Decreased HRQOL was associated with more frequent flares and presence of tophi. In multivariable models predicting outcomes based on presence of tophi and number of flares, both flares (≥4 and tophi (≥1 were associated with HRQOL decrements on physical and mental component summary scores and health utilities (all p  Conclusions Impairments associated with gout flares and presence of tophi, across patients in the US and EU, underscore the importance of effective management of this potentially curable condition.

    What makes a successful team? In this issue our contributors look closely at the subject and come up with several answers. Working on team chemistry is the "Activation Energy" Dr. Owen Gadeken's story is about. Scott Cameron thinks it's getting to know people one to one. Tony Maturo says it's getting the most out of your support staff. Dr. Michael Hecht finds the best people he can and build the team around their talents. Teamwork is a theme we explore often in Academy Sharing Knowledge (ASK), but never so directly as in this issue. You'll not only find formulas for building successful teams, you'll see examples of ones in action, strategies for how project managers can motivate their teams, and expert advice on how to choose who to work with and who not to work with. It seems like all the stories make one common point: everyone on a team counts. Few project managers can pull off a project alone, and when the whole team is performing to everyone's potential, the chances of pulling off a successful project goes up exponentially. If that doesn't seem like enough by itself, listen to this... Discerning fans of ASK will note the last two issues our Special Feature was "There are no Mistakes, Only Lessons." We have not abandoned this feature, but for now we want to broaden our repertoire. In this issue we add a new Special Feature, "My Metaphor," starting with Paul Espinosa's article "My Big Wall" about his rock climbing adventures on El Capitan in Yosemite National Park. If you think getting to Mars is work, read what it's like to scale a 3,000-foot rock face. This issue we're also welcoming two new members to our Review Board, Hugh Woodward and Jody Kusek. Hugh and Jody are our first reviewers from outside NASA, and we are delighted to have them on our team. Read their bios on the ASK Review Board page and see why we feel privileged to have them on our team.

  8. Relationship Between Frequent Recreational Cannabis (Marijuana and Hashish) Use and Periodontitis in Adults in the United States: National Health and Nutrition Examination Survey 2011 to 2012. (United States)

    Shariff, Jaffer A; Ahluwalia, Kavita P; Papapanou, Panos N


    Recreational use of cannabis, following its legalization in some countries, poses emergent oral and periodontal health concerns. The objective of this study is to examine the relationship between frequent recreational cannabis (FRC) (marijuana and hashish) use and periodontitis prevalence among adults in the United States. Data from the National Health and Nutrition Examination Survey (NHANES) 2011 to 2012 were analyzed. Primary outcome (periodontitis) was defined using the Centers for Disease Control and Prevention/American Academy of Periodontology classification as well as continuous measurements of probing depth (PD) and clinical attachment loss (AL). Exposure of interest was self-reported cannabis use, defined as "FRC use" versus "non-FRC use." Bivariate and multivariable regression models were performed using the entire analytical sample (model 1) as well as those who had never used tobacco (never-users) (model 2). Of 1,938 participants with available cannabis use data and essential covariates, 26.8% were FRC users. Mean number of sites per participant with PD ≥4, ≥6, and ≥8 mm and AL ≥3, ≥5, and ≥8 mm was significantly higher among FRC users than among non-FRC users (mean difference in number of PD sites: 6.9, 5.6, and 5.6; P <0.05; mean difference in number of AL sites: 12.7, 7.6, and 5.6; P <0.05). Average AL was higher among FRC users than among non-FRC users (1.8 versus 1.6 mm; P = 0.004). Bivariate analysis revealed positive (harmful) association between FRC use and severe periodontitis in the entire sample (odds ratio [OR]: 1.7, 95% confidence interval [CI]: 1.3 to 2.4; P = 0.002) as well as in never-smokers (OR: 2.0, 95% CI: 1.2 to 3.5; P = 0.01). This association was retained in multivariable models adjusted for demographics (age, sex, race/ethnicity, and income level), alcohol and tobacco use, diabetes mellitus, and past periodontal treatment (model 1: adjusted OR [aOR]: 1.4, 95% CI: 1.1 to 1.9; P = 0.07; model 2: aOR: 1.9, 95% CI: 1

    THIS ISSUE FEATURES A VISUAL DEPICTION OF THE ACADEMY of Program and Project Leadership (APPL). I imagine a variety of initial reactions to the drawing. One might be, "What is a cartoon doing in a magazine about project management?" Or perhaps, "Wow, nice colors-and fun." Another may be to closely search the image for signs, symbols and meaning. Still another, to read a new level of innovation and creativity into the picture. Undoubtedly, some readers will raise questions about the cost. Of course, any reaction is a sign of engagement. The stronger, the more energized the emotional and cognitive processing, the better. It is a sign of attention and interaction. For I've heard it said, "You only need to worry if they don t care one way or the other." So what is the point of the picture? To stimulate interest, raise questions, promote discussion, and maybe raise a smile.. .That, at least, was my initial reaction when I was introduced to the work of Nancy Hegedus, who helps to create these drawings for Root Learning Inc. At the NASA PM Conference, I was first shown the work Nancy had been doing with the help of Goddard s Knowledge Management Architect, Dr. Ed Rogers. I was immediately drawn into the power of visualization as a tool for more effective learning, communicating, and conveying complex knowledge concepts. We need new tools in today s world, where information and data overwhelms by sheer volume. There are articles, pamphlets, communications, and white papers-all aiming to convince and influence. Reactions to these tend to be either avoidance or mind-numbing, heavy-eyed consent; the message never registers or enters the soul. That s one of the reasons that APPL s Knowledge Sharing Initiative (KSI) has turned to storytelling as a memorable way of transfer- ring knowledge, inspiring imitation of best practices, and spurring reflection. ASK Magazine s recent fourth birthday marks an important milestone in APPL s continuing quest to provide ongoing support to

  10. How do frequent users of crisis helplines differ from other users regarding their reasons for calling? Results from a survey with callers to Lifeline, Australia's national crisis helpline service. (United States)

    Middleton, Aves; Woodward, Alan; Gunn, Jane; Bassilios, Bridget; Pirkis, Jane


    Crisis helplines are designed to provide short-term support to people in an immediate crisis. However, there is a group of users who call crisis helplines frequently over an extended period of time. The reasons for their ongoing use remain unclear. The aim of this study was to investigate the differences in the reasons for calling between frequent and other users of crisis helplines. This was achieved by examining the findings from a brief survey completed by callers to Lifeline Australia at the end of their call between February and July 2015. In the survey, callers reported on their socio-demographics, reasons for their current call and number of calls made in the past month. Survey respondents were categorised as frequent, episodic and one-off users, and analyses were conducted using ordered logistic regression. Three hundred and fifteen callers completed the survey, which represented 57% of eligible callers. Twenty-two per cent reported calling 20 times or more in the past month (frequent users), 51% reported calling between 2 and 19 times (episodic users) and 25% reported calling once (one-off users). Two per cent were unable to recall the number of calls they made in the past month. Frequent users reported similar reasons for calling as other users but they were more likely to call regularly to talk about their feelings [OR = 6.0; 95% CI: 3.7-9.8]. This pattern of service use is at odds with the current model of care offered by crisis helplines which is designed to provide one-off support. There is a need to investigate further the factors that drive frequent users to call crisis helplines regularly. © 2016 John Wiley & Sons Ltd.

  13. Frequent and systematic unprotected anal intercourse among men using the Internet to meet other men for sexual purposes in France: results from the "Gay Net Barometer 2006" survey. (United States)

    Léobon, Alain; Frigault, Louis-Robert


    For men who have sex with men (MSM), the Internet has imposed itself in the past decade as the place to be to meet other men with similar interests for sex or just to surf in search of excitement. This is a biennial study on the MSM in France. Between December 2005 and February 2006, 15,085 MSM completed an online questionnaire on their social and sexual uses of the Internet. Participants in the "The Gay Net Barometer 2006" study responded to questions related to their sexual and sexual risk behaviours. One third of respondents reported at least one event of unprotected anal intercourse while 11.1% reported frequent or systematic unprotected anal intercourse. These sexual risk behaviours were associated with various sociodemographic and sexual variables in addition to the recruitment website. The study suggests Internet users are not a homogeneous group and intervention targeting of them should be based on an in-depth understanding of the sexual cultures operating within websites.

    Perrier Laure-Lou


    Full Text Available Abstract The exponential development of Patient-Reported Outcomes (PRO measures in clinical research has led to the creation of the Patient-Reported Outcome and Quality of Life Instruments Database (PROQOLID to facilitate the selection process of PRO measures in clinical research. The project was initiated by Mapi Research Trust in Lyon, France. Initially called QOLID (Quality of Life Instruments Database, the project's purpose was to provide all those involved in health care evaluation with a comprehensive and unique source of information on PRO and HRQOL measures available through the Internet. PROQOLID currently describes more than 470 PRO instruments in a structured format. It is available in two levels, non-subscribers and subscribers, at The first level is free of charge and contains 14 categories of basic useful information on the instruments (e.g. author, objective, original language, list of existing translations, etc.. The second level provides significantly more information about the instruments. It includes review copies of over 350 original instruments, 120 user manuals and 350 translations. Most are available in PDF format. This level is only accessible to annual subscribers. PROQOLID is updated in close collaboration with the instruments' authors on a regular basis. Fifty or more new instruments are added to the database annually. Today, all of the major pharmaceutical companies, prestigious institutions (such as the FDA, the NIH's National Cancer Institute, the U.S. Veterans Administration, dozens of universities, public institutions and researchers subscribe to PROQOLID on a yearly basis. More than 800 users per day routinely visit the database.

  15. Scalable Frequent Subgraph Mining

    KAUST Repository

    Abdelhamid, Ehab


    A graph is a data structure that contains a set of nodes and a set of edges connecting these nodes. Nodes represent objects while edges model relationships among these objects. Graphs are used in various domains due to their ability to model complex relations among several objects. Given an input graph, the Frequent Subgraph Mining (FSM) task finds all subgraphs with frequencies exceeding a given threshold. FSM is crucial for graph analysis, and it is an essential building block in a variety of applications, such as graph clustering and indexing. FSM is computationally expensive, and its existing solutions are extremely slow. Consequently, these solutions are incapable of mining modern large graphs. This slowness is caused by the underlying approaches of these solutions which require finding and storing an excessive amount of subgraph matches. This dissertation proposes a scalable solution for FSM that avoids the limitations of previous work. This solution is composed of four components. The first component is a single-threaded technique which, for each candidate subgraph, needs to find only a minimal number of matches. The second component is a scalable parallel FSM technique that utilizes a novel two-phase approach. The first phase quickly builds an approximate search space, which is then used by the second phase to optimize and balance the workload of the FSM task. The third component focuses on accelerating frequency evaluation, which is a critical step in FSM. To do so, a machine learning model is employed to predict the type of each graph node, and accordingly, an optimized method is selected to evaluate that node. The fourth component focuses on mining dynamic graphs, such as social networks. To this end, an incremental index is maintained during the dynamic updates. Only this index is processed and updated for the majority of graph updates. Consequently, search space is significantly pruned and efficiency is improved. The empirical evaluation shows that the

  3. "This is a question we have to ask everyone": asking young people about self-harm and suicide. (United States)

    O'Reilly, M; Kiyimba, N; Karim, K


    WHAT IS KNOWN ON THE SUBJECT?: An essential part of the mental health assessment is to evaluate the risk of harm to self. Fundamentally this involves asking directly about self-harming behaviour and suicidal thoughts or urges, but practitioners often find it difficult to open up these conversations. This evaluation of risk is particularly important as self-harm and suicidal thoughts are frequently found in young people who attend mental health services. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Young people are not always routinely asked directly about self-harm or suicidal thoughts when they are assessed. There are two ways that mental health practitioners introduce this topic: first, by building up to it by initially asking about general feelings, and second by stating that it is a requirement to ask everyone. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: These questions should not be avoided by mental health practitioners just because they are difficult. We offer suggestions as to how to ask questions about self-harm and suicide based on real-world practice.

  4. Parallel Frequent Pattern Discovery: Challenges and Methodology

    Institute of Scientific and Technical Information of China (English)


    Parallel frequent pattern discovery algorithms exploit parallel and distributed computing resources to relieve the sequential bottlenecks of current frequent pattern mining (FPM) algorithms. Thus, parallel FPM algorithms achieve better scalability and performance, so they are attracting much attention in the data mining research community. This paper presents a comprehensive survey of the state-of-the-art parallel and distributed frequent pattern mining algorithms with more emphasis on pattern discovery from complex data (e.g., sequences and graphs) on various platforms. A review of typical parallel FPM algorithms uncovers the major challenges, methodologies, and research problems in the field of parallel frequent pattern discovery,such as work-load balancing, finding good data layouts, and data decomposition. This survey also indicates a dramatic shift of the research interest in the field from the simple parallel frequent itemset mining on traditional parallel and distributed platforms to parallel pattern mining of more complex data on emerging architectures, such as multi-core systems and the increasingly mature grid infrastructure.

    Directory of Open Access Journals (Sweden)

    D.Bujji Babu


    Full Text Available Association rule learning is a popular and well researched technique for discovering interesting relations between variables in large databases in the area of data mining. The association rules are a part of intelligent systems. Association rules are usually required to satisfy a user-specified minimum support and a user-specified minimum confidence at the same time. Apriori and FP-Growth algorithms are very familiar algorithms for association rule mining. In this paper we are more concentrated on the Construction of efficient frequent pattern trees. Here, we present the novel frequent pattern trees and the performance issues. The proposed trees are fast and efficient trees helps to extract the frequent patterns. This paper provides the major advantages in the FP-Growth algorithm for association rule mining with using the newly proposed approach.

  4. Learning How to Ask: Women and Negotiation. (United States)

    Fischer, Lauren H; Bajaj, Anureet K


    Women are less likely to reach top-level leadership positions, and more likely to leave academic positions, than men, and are likely to earn less money than men. Women are also less likely to initiate a negotiation-a process that is crucial for professional advancement. This reluctance to ask hinders their advancement and can have long-lasting consequences-both financial and professional. The reasons that women do not ask are multifactorial. In this article, we will explore reasons why women are less likely to negotiate, the barriers they face when they do, and strategies that women can apply to improve their negotiation skills.

  14. Why physicians and nurses ask (or don’t about partner violence: a qualitative analysis

    Directory of Open Access Journals (Sweden)

    Beynon Charlene E


    Full Text Available Abstract Background Intimate partner violence (IPV against women is a serious public health issue and is associated with significant adverse health outcomes. The current study was undertaken to: 1 explore physicians’ and nurses’ experiences, both professional and personal, when asking about IPV; 2 determine the variations by discipline; and 3 identify implications for practice, workplace policy and curriculum development. Methods Physicians and nurses working in Ontario, Canada were randomly selected from recognized discipline-specific professional directories to complete a 43-item mailed survey about IPV, which included two open-ended questions about barriers and facilitators to asking about IPV. Text from the open-ended questions was transcribed and analyzed using inductive content analysis. In addition, frequencies were calculated for commonly described categories and the Fisher’s Exact Test was performed to determine statistical significance when examining nurse/physician differences. Results Of the 931 respondents who completed the survey, 769 (527 nurses, 238 physicians, four whose discipline was not stated provided written responses to the open-ended questions. Overall, the top barriers to asking about IPV were lack of time, behaviours attributed to women living with abuse, lack of training, language/cultural practices and partner presence. The most frequently reported facilitators were training, community resources and professional tools/protocols/policies. The need for additional training was a concern described by both groups, yet more so by nurses. There were statistically significant differences between nurses and physicians regarding both barriers and facilitators, most likely related to differences in role expectations and work environments. Conclusions This research provides new insights into the complexities of IPV inquiry and the inter-relationships among barriers and facilitators faced by physicians and nurses. The

  20. Ask, advise, assist: pediatricians and passive smoke exposure. (United States)

    Burnett, K F; Young, P C


    The objectives of this study were to determine: (1) how frequently pediatricians obtain a history of passive smoke exposure (PSE), (2) what type of advice regarding PSE they offer and how frequently they offer it, and (3) what methods and what assistance they believe would be useful to reduce PSE. A random sample of 1,000 US members (GEN) of the American Academy of Pediatrics (AAP) and all 724 members of the AAP sections of pulmonology, otolaryngology, and allergy (SPECS) were sent a questionnaire. Seven hundred fifty-five usable questionnaires were returned. Ninety-six percent of 321 general pediatricians obtained a PSE history at least "sometimes" but were much more likely to "always" do so when seeing a patient with asthma (87%) or recurrent otitis media (56%) than during well-child visits (41%) (p smoke around the child," or "quit smoking." Reasons for not initiating a cessation program included lack of skills (38%) or time (36%) or a belief that it was "not their responsibility" (13%). Pediatricians indicated that brochures for parents that describe the hazards of PSE and contain specific information regarding how to refer to community smoking cessation programs would be of most use to them in helping parents reduce PSE to their children. Pediatricians frequently ask about PSE and advise reducing it but seldom assist parents with specific advice regarding effective methods to quit smoking.

  5. Fault Tolerant Frequent Pattern Mining

    Energy Technology Data Exchange (ETDEWEB)

    Shohdy, Sameh; Vishnu, Abhinav; Agrawal, Gagan


    FP-Growth algorithm is a Frequent Pattern Mining (FPM) algorithm that has been extensively used to study correlations and patterns in large scale datasets. While several researchers have designed distributed memory FP-Growth algorithms, it is pivotal to consider fault tolerant FP-Growth, which can address the increasing fault rates in large scale systems. In this work, we propose a novel parallel, algorithm-level fault-tolerant FP-Growth algorithm. We leverage algorithmic properties and MPI advanced features to guarantee an O(1) space complexity, achieved by using the dataset memory space itself for checkpointing. We also propose a recovery algorithm that can use in-memory and disk-based checkpointing, though in many cases the recovery can be completed without any disk access, and incurring no memory overhead for checkpointing. We evaluate our FT algorithm on a large scale InfiniBand cluster with several large datasets using up to 2K cores. Our evaluation demonstrates excellent efficiency for checkpointing and recovery in comparison to the disk-based approach. We have also observed 20x average speed-up in comparison to Spark, establishing that a well designed algorithm can easily outperform a solution based on a general fault-tolerant programming model.

  6. [Osmolality of frequently consumed beverages]. (United States)

    Dini, Elizabeth; De Abreu, Jorge; López, Emeris


    The objective of this work was to determine the osmolality of beverages frequently consumed by children and adolescents due to the scarce information available in our country. The samples were grouped as follows: milks; refreshments; beverages based on fruits, vegetables, cereals, and tubers; sport drinks; energizing drinks; oral rehydrating solutions; reconstituted drinks and infusions. A vapor pressure digital osmometer was used, five samples of each beverage from different lots were analyzed. Four osmolality determinations were made on each sample and the average of such values was calculated. When the variation coefficient of the osmolality measurements of the five samples was higher than 10%, five additional samples were analyzed. As many samples as possible were used with breast milk in the time period of the study. Osmolality averages, standard deviation, and the osmolality confidence intervals (95% reliability) were calculated. The osmolality (mmol/kg) of breast milk and that of cow milk were between 273 and 389; refreshments, white, black and flavored colas, and malts ranged between 479-811; and soda and light drinks: 44-62; fresh fruit and commercial drinks (coconut, peach, apple, orange, pear, pineapple, grape, plum, tamarind): 257-1152 and light juices: 274; sports beverages: 367; energizing drinks: 740; drinks based on vegetables and cereals: 213-516; oral rehydrating solutions: 236-397; reconstituted drinks: 145; infusions: 25. Beverages with adequate osmolality levels for children were: milks, light refreshments, soda, fresh and light juices, oral rehydrating, soy, and reconstituted drinks and infusions.

  7. Asking for a Commitment: Violations during the 2007 Match and the Effect on Applicant Rank Lists

    Directory of Open Access Journals (Sweden)

    Hern, Gene H.


    Full Text Available Introduction: Applicants to residency face a number of difficult questions during the interview process, one of which is when a program asks for a commitment to rank the program highly. The regulations governing the National Resident Matching Program (NRMP match explicitly forbid any residency programs asking for a commitment. Methods: We conducted a cross-sectional survey of applicants from U.S. medical schools to five specialties during the 2006-2007 interview season using the Electronic Residency Application Service of the Association of American Medical Colleges. Applicants were asked to recall being asked to provide any sort of commitment (verbal or otherwise to rank a program highly. Surveys were sent after rank lists were submitted, but before match day. We analyzed data using descriptive statistics and logistic regression. Results: There were 7,028 unique responses out of 11,983 surveys sent for a response rate of 58.6%. Of those who identified their specialty (emergency medicine, internal medicine, obstetrics and gynecology [OBGYN], general surgery and orthopedics, there were 6,303 unique responders. Overall 19.6% (1380/7028 of all respondents were asked to commit to a program. Orthopedics had the highest overall prevalence at 28.9% (372/474, followed by OBGYN (23.7%; 180/759, general surgery (21.7%; 190/876, internal medicine (18.3%; 601/3278, and finally, emergency medicine (15.4%; 141/916. Of those responding, 38.4% stated such questions made them less likely to rank the program. Conclusion: Applicants to residencies are being asked questions expressly forbidden by the NRMP. Among the five specialties surveyed, orthopedics and OBGYN had the highest incidence of this violation. Asking for a commitment makes applicants less likely to rank a program highly.

  8. The frequent occurrence of MIC

    Energy Technology Data Exchange (ETDEWEB)

    Graff, Matthias [Gesellschaft fuer Technische Mikrobiologie und Hygieneueberwachung - Dr. Graff und Partner, Stadtweg 9, D-38176 Wendeburg (Germany); Neubert, Volkmar [Institut fuer Materialpruefung und Werkstofftechnik Dr. Doelling und Dr. Neubert GmbH, Freiberger Strasse 1, D-38678 Clausthal-Zellerfeld (Germany)


    Microbial induced corrosion (MIC) is not as rare as many materials scientist and corrosion practitioners do believe. It is not an exotic and scarce event, but can be found frequently in many fields of corrosion research, provided that it is looked for. The reason for the relatively few descriptions of MIC cases seems to be the fact, that the microbiological approach is not widely known and applied in the world of materials science. MIC is not so much a corrosion mechanism on its own, but it enhances the corrosion rates of the 'normal' mechanisms to such an extent, that in some cases 'incredible' fast corrosion progress can be observed. The reason is the microorganisms' function as bio-catalysts: Chemical reactions, which are very slow under normal chemical conditions can be highly accelerated by living organisms. Besides that, several microorganisms do produce very corrosive substances which in natural environments do not occur without the activity of microorganisms, e. g. sulfuric or nitric acid. We want to point out, that it can be very worthy to take microbial induced corrosion into account. MIC is not the general answer for all unsolved corrosion problems, but to think about it helps in many corrosion cases as the authors had to experience. The initial indication for the presence of MIC are markedly increased corrosion rates. In the following, some of our 'lessons' are presented as short case studies: Two of them deal with steel corrosion characterized by increased corrosion rates. The third example presents corrosion damage of aluminium structures, where from a technical point of view corrosion was not expected, least of all microbial induced corrosion. (authors)

  9. Lower life satisfaction related to materialism in children frequently exposed to advertising. (United States)

    Opree, Suzanna J; Buijzen, Moniek; Valkenburg, Patti M


    Research among adults suggests that materialism and life satisfaction negatively influence each other, causing a downward spiral. So far, cross-sectional research among children has indicated that materialistic children are less happy, but causality remains uncertain. This study adds to the literature by investigating the longitudinal relation between materialism and life satisfaction. We also investigated whether their relation depended on children's level of exposure to advertising. A sample of 466 children (aged 8-11; 55% girls) participated in a 2-wave online survey with a 1-year interval. We asked children questions about material possessions, life satisfaction, and advertising. We used structural equation modeling to study the relationship between these variables. For the children in our sample, no effect of materialism on life satisfaction was observed. However, life satisfaction did have a negative effect on materialism. Exposure to advertising facilitated this effect: We only found an effect of life satisfaction on materialism for children who were frequently exposed to advertising. Among 8- to 11-year-old children, life satisfaction leads to decreased materialism and not the other way around. However, this effect only holds for children who are frequently exposed to television advertising. It is plausible that the material values portrayed in advertising teach children that material possessions are a way to cope with decreased life satisfaction. It is important to reduce this effect, because findings among adults suggest that materialistic children may become less happy later in life. Various intervention strategies are discussed.

  2. Are Healthcare Providers Asking about Environmental Exposures? A Community-Based Mixed Methods Study

    Directory of Open Access Journals (Sweden)

    Kristina M. Zierold


    Full Text Available People living near environmental hazards may develop symptoms and health conditions that require specialized monitoring and treatment by healthcare providers. One emerging environmental hazard is coal ash. Coal ash is comprised of small particles containing heavy metals, polycyclic aromatic hydrocarbons, and radioactive elements. The overall purpose of this study was to explore whether healthcare providers ask patients if they live near an environmental hazard like coal ash storage sites and to assess what health conditions prompt a provider inquiry. Focus groups were conducted in 2012 and a cross-sectional survey was administered in 2013. Overall, 61% of survey respondents reported that their healthcare providers never asked if they lived near an environmental hazard. One focus group member stated “No, they don’t ask that. They just always blame stuff on you….” Respondents with asthma and other lung conditions were significantly more likely to be asked by a healthcare provider if they lived near an environmental hazard. Due to the unique exposures from environmental hazards and the low prevalence of patients being asked about environmental hazards, we recommend that healthcare providers take environmental health histories in order to understand patients’ exposures, to monitor symptoms of exposure, and to assist with education about reducing exposure.

  3. An exploratory study of patient's feelings about asking healthcare professionals to wash their hands. (United States)

    Duncan, C


    The purpose of this study was to explore patient opinion about asking healthcare professionals to wash their hands prior to a clinical procedure and to explore if MRSA status and access to patient information about infection control would influence anxiety about asking. A descriptive survey was undertaken using a semi-structured questionnaire. The questionnaire was distributed to a randomised convenience sample of 185 in-patients across all departments of an acute NHS Trust hospital (response rate 59.4%). Spearman's rank order and Kendall Tau-b tests were used to analyse specific correlations. Respondents were more confident than anxious to be involved in a campaign that asked patients to ask staff to wash their hands. Patients were more anxious to ask if previous admission episodes were fewer, if their knowledge of MRSA was high and if there was less information about infection control available. Less anxiety was associated with patients who had MRSA in the past and the suggestion that staff wore badges saying 'It's OK to ask'.

  4. Perceived Quality of Social Relations and Frequent Drunkenness

    DEFF Research Database (Denmark)

    Kjærulff, Thora M; Rivera, Francisco; Jiménez-Iglesias, Antonia


    AIM: The aim of the study was to examine, for female and male students separately, whether perceived quality of relationships with peers and parents and relations in school predict self-reported frequent drunkenness among Spanish adolescents. METHODS: The Spanish data from the Health Behaviour...... in School-aged Children Study (HBSC) 2010 survey were used including 1177 female and 1126 male students aged between 15 and 16 years.

  5. Reasons for Supporting the Minimum Wage: Asking Signatories of the "Raise the Minimum Wage" Statement



    In October 2006, the Economic Policy Institute released a “Raise the Minimum Wage†statement signed by more than 650 individuals. Using an open-ended, non-anonymous questionnaire, we asked the signatories to explain their thinking on the issue. The questionnaire asked about the specific mechanisms at work, possible downsides, and whether the minimum wage violates liberty. Ninety-five participated. This article reports the responses. It also summarizes findings from minimum-wage surveys sin...

  6. Quantifying fluctuations in market liquidity: analysis of the bid-ask spread. (United States)

    Plerou, Vasiliki; Gopikrishnan, Parameswaran; Stanley, H Eugene


    Quantifying the statistical features of the bid-ask spread offers the possibility of understanding some aspects of market liquidity. Using quote data for the 116 most frequently traded stocks on the New York Stock Exchange over the two-year period 1994-1995, we analyze the fluctuations of the average bid-ask spread S over a time interval deltat. We find that S is characterized by a distribution that decays as a power law P[S>x] approximately x(-zeta(S) ), with an exponent zeta(S) approximately = 3 for all 116 stocks analyzed. Our analysis of the autocorrelation function of S shows long-range power-law correlations, (S(t)S(t + tau)) approximately tau(-mu(s)), similar to those previously found for the volatility. We next examine the relationship between the bid-ask spread and the volume Q, and find that S approximately ln Q; we find that a similar logarithmic relationship holds between the transaction-level bid-ask spread and the trade size. We then study the relationship between S and other indicators of market liquidity such as the frequency of trades N and the frequency of quote updates U, and find S approximately ln N and S approximately ln U. Lastly, we show that the bid-ask spread and the volatility are also related logarithmically.

  7. I Wish I'd Asked That: The Culture of Asking Questions in Astronomy (United States)

    Baleisis, Audra


    I will present the results from a qualitative study of the values and norms for thinking about science in academic astronomy, as seen through astronomers’ beliefs about departmental speech events. In-depth interviews were carried out with 12 graduate students and 9 faculty members from a prominent astronomy department at a large, public university. Interviewees were asked about a variety of speaking events in their department. The speaking events chosen were those at which: (1) graduate students could be presenters and/or ask questions, and (2) presenters spoke about science research to an audience of academic peers. This included Coffee Hour, Journal Club, research seminars, Colloquium, and dissertation defense talks. These events are part of the socialization of students into "acting like an astronomer.” Socialization is a process by which novices learn the rules (can and can't do), norms (should and shouldn't do), and values of a culture. The values of astronomy culture are encoded within the rules for participation in these events and the assumptions that audience members make about speakers. When these values contradict each other speakers face the dilemma of choosing between conflicting behaviors. One of the central dilemmas that arose in this study was that of whether or not to ask a question during a talk. Both graduate students and faculty members wanted students to speak up more often. However, students had conflicting worries - of voicing a question and it being a "stupid question” vs. having remained silent if it turned out to have been a "good question.” I will argue that this anxiety is a product of academic culture and not an indicator of individual failure, and discuss a number of factors that influence this situation, such as the perceived goals of each event, and astronomers’ beliefs about intelligence and learning.

  8. Characterization of the occult nature of injury for frequently occurring motor vehicle crash injuries. (United States)

    Schoell, Samantha L; Doud, Andrea N; Weaver, Ashley A; Talton, Jennifer W; Barnard, Ryan T; Winslow, James E; Stitzel, Joel D


    Occult injuries are not easily detected and can be potentially life-threatening. The purpose of this study was to quantify the perceived occultness of the most frequent motor vehicle crash injuries according to emergency medical services (EMS) professionals. An electronic survey was distributed to 1,125 EMS professionals who were asked to quantify the likelihood that first responders would miss symptoms related to a particular injury on a 5-point Likert scale. The Occult Score for each injury was computed from the average of all the survey responses and normalized to be a continuous metric ranging from 0 to 1 where 0 is a non-occult (highly apparent on initial presentation) injury and 1 is an occult (unapparent on initial presentation) injury. Overall, 110,671 survey responses were collected. The Occult Score ranged from 0 to 1 with a mean, median, and standard deviation of 0.443, 0.450, and 0.233, respectively. When comparing the Occult Score of an injury to its corresponding AIS severity, there was no relationship between the metrics. When stratifying by body region, injury type, and AIS severity, it was evident that AIS 2-4 abdominal injuries with lacerations, hemorrhage, or contusions were perceived as the most occult injuries. Timely triage is key to reduce the morbidity and mortality associated with occult injuries. The Occult Score developed in this study to describe the predictability of an injury in a motor vehicle crash will be used as part of a larger effort, including incorporation into an advanced automatic crash notification (AACN) algorithm to detect crash conditions associated with a patient's need for prompt treatment at a trauma center.

  9. Medicinal plants used to treat the most frequent diseases encountered in Ambalabe rural community, Eastern Madagascar. (United States)

    Rakotoarivelo, Nivo H; Rakotoarivony, Fortunat; Ramarosandratana, Aro Vonjy; Jeannoda, Vololoniaina H; Kuhlman, Alyse R; Randrianasolo, Armand; Bussmann, Rainer W


    Traditional medicine remains the only health care available in many rural areas in Madagascar like the rural community of Ambalabe, located in a very remote area in the eastern part of the country. With limited access to modern medicine, the local population uses medicinal plants to treat most diseases. In this study, we aimed to inventory medicinal plants used by local people and how those relate to the treatment of the most frequent diseases encountered in Ambalabe. We interviewed participants in order to identify the most frequent diseases in the region and the medicinal plants used to treat them. The local physician was asked about the most frequent diseases, and ethnobotanical surveys to record medicinal plants and their uses, using semi-structured interviews and free listing, were conducted among 193 informants in local villages, of which 54 % were men and 46 % were women, ageing from 16 to 86 years. The local names, the uses of each plant species and the way they are prepared and administered were recorded and accompanied by herbarium specimens for identification. We also interviewed four traditional healers to elicit more details on the preparation and the use of plants. Our research allowed us to identify six most frequent diseases, namely diarrhea, malaria, stomach-ache, cough, bilharzia and dysentery. Among 209 plant species identified as having medicinal use, 83 species belonging to 49 families and 77 genera were used to treat these diseases. Our analyses highlighted the 11 commonly used species for their treatment, and also 16 species with a high fidelity level (FL ≥ 75 %) for each ailment. Diarrhea is one of the diseases with high number of species recorded. This study highlighted the closed relationship between people in Ambalabe and plant species, especially when faced with frequent diseases. However, most of the species used were collected in the surroundings of the villages. Few species were from Vohibe forest in which a management system on

  10. Questionnaire Designing for a Survey

    Directory of Open Access Journals (Sweden)

    S Roopa


    Full Text Available Questionnaires are frequently used in quantitative marketing research and social research. A questionnaire is a series of questions asked to individuals to obtain statistically useful information about a given topic. When properly constructed and responsibly administered, questionnaires become a vital instrument by which statements can be made about specific groups or people or entire populations. They are a valuable method of collecting a wide range of information from a large number of individuals, often referred to as respondents. Adequate questionnaire construction is critical to the success of a survey. Appropriate questions, correct ordering of questions, correct scaling, or good questionnaire format can make the survey worthwhile, as it may accurately reflect the views and opinions of the participants. A useful method for checking a questionnaire and making sure it is accurately capturing the intended information is to pretest among a smaller subset of target respondents.

  12. Maximal Frequent Itemset Generation Using Segmentation Apporach

    Directory of Open Access Journals (Sweden)



    Full Text Available Finding frequent itemsets in a data source is a fundamental operation behind Association Rule Mining.Generally, many algorithms use either the bottom-up or top-down approaches for finding these frequentitemsets. When the length of frequent itemsets to be found is large, the traditional algorithms find all thefrequent itemsets from 1-length to n-length, which is a difficult process. This problem can be solved bymining only the Maximal Frequent Itemsets (MFS. Maximal Frequent Itemsets are frequent itemsets whichhave no proper frequent superset. Thus, the generation of only maximal frequent itemsets reduces thenumber of itemsets and also time needed for the generation of all frequent itemsets as each maximal itemsetof length m implies the presence of 2m-2 frequent itemsets. Furthermore, mining only maximal frequentitemset is sufficient in many data mining applications like minimal key discovery and theory extraction. Inthis paper, we suggest a novel method for finding the maximal frequent itemset from huge data sourcesusing the concept of segmentation of data source and prioritization of segments. Empirical evaluationshows that this method outperforms various other known methods.

    Full Text Available Objective. Frequent insufficient sleep, defined as ≥14 days/past 30 days in which an adult did not get enough rest or sleep, is associated with adverse mental and physical health outcomes. Little is known about the prevalence of frequent insufficient sleep among American Indians/Alaska Natives (AI/AN. Methods. We assessed racial/ethnic differences in the prevalence of frequent insufficient sleep from the combined 2009-2010 Behavioral Risk Factor Surveillance Survey among 810,168 respondents who self-identified as non-Hispanic white (NHW, , non-Hispanic black (NHB, , Hispanic (, or AI/AN (. Results. We found significantly higher unadjusted prevalences (95% CI of frequent insufficient sleep among AI/AN (34.2% [32.1–36.4] compared to NHW (27.4% [27.1–27.6]. However, the age-adjusted excess prevalence of frequent insufficient sleep in AI/AN compared to NHW was decreased but remained significant with the addition of sex, education, and employment status; this latter relationship was further attenuated by the separate additions of obesity and lifestyle indicators, but was no longer significant with the addition of frequent mental distress to the model (PR  =  1.05; 95% CI : 0.99–1.13. This is the first report of a high prevalence of frequent insufficient sleep among AI/AN. These results further suggest that investigation of sleep health interventions addressing frequent mental distress may benefit AI/AN populations.

  15. Development of a time sensitivity score for frequently occurring motor vehicle crash injuries. (United States)

    Schoell, Samantha L; Doud, Andrea N; Weaver, Ashley A; Talton, Jennifer W; Barnard, Ryan T; Martin, R Shayn; Meredith, J Wayne; Stitzel, Joel D


    Injury severity alone is a poor indicator of the time sensitivity of injuries. The purpose of the study was to quantify the urgency with which the most frequent motor vehicle crash injuries require treatment, according to expert physicians. The time sensitivity was quantified for the top 95% most frequently occurring Abbreviated Injury Scale (AIS) 2+ injuries in the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) 2000-2011. A Time Sensitivity Score was developed using expert physician survey data in which physicians were asked to determine whether a particular injury should go to a Level I/II trauma center and the urgency with which that injury required treatment. When stratifying by AIS severity, the mean Time Sensitivity Score increased with increasing AIS severity. The mean Time Sensitivity Scores by AIS severity were as follows: 0.50 (AIS 2); 0.78 (AIS 3); 0.92 (AIS 4); 0.97 (AIS 5); and 0.97 (AIS 6). When stratifying by anatomical region, the head, thorax, and abdomen were the most time sensitive. Appropriate triage depends on multiple factors, including the severity of an injury, the urgency with which it requires treatment, and the propensity of a significant injury to be missed. The Time Sensitivity Score did not correlate highly with the widely used AIS severity scores, which highlights the inability of AIS scores to capture all aspects of injury severity. The Time Sensitivity Score can be useful in Advanced Automatic Crash Notification systems for identifying highly time sensitive injuries in motor vehicle crashes requiring prompt treatment at a trauma center.

  16. Mining Frequent Itemsets in Correlated Uncertain Databases

    Institute of Scientific and Technical Information of China (English)

    童咏昕; 陈雷; 佘洁莹


    Recently, with the growing popularity of Internet of Things (IoT) and pervasive computing, a large amount of uncertain data, e.g., RFID data, sensor data, real-time video data, has been collected. As one of the most fundamental issues of uncertain data mining, uncertain frequent pattern mining has attracted much attention in database and data mining communities. Although there have been some solutions for uncertain frequent pattern mining, most of them assume that the data is independent, which is not true in most real-world scenarios. Therefore, current methods that are based on the independent assumption may generate inaccurate results for correlated uncertain data. In this paper, we focus on the problem of mining frequent itemsets over correlated uncertain data, where correlation can exist in any pair of uncertain data objects (transactions). We propose a novel probabilistic model, called Correlated Frequent Probability model (CFP model) to represent the probability distribution of support in a given correlated uncertain dataset. Based on the distribution of support derived from the CFP model, we observe that some probabilistic frequent itemsets are only frequent in several transactions with high positive correlation. In particular, the itemsets, which are global probabilistic frequent, have more significance in eliminating the influence of the existing noise and correlation in data. In order to reduce redundant frequent itemsets, we further propose a new type of patterns, called global probabilistic frequent itemsets, to identify itemsets that are always frequent in each group of transactions if the whole correlated uncertain database is divided into disjoint groups based on their correlation. To speed up the mining process, we also design a dynamic programming solution, as well as two pruning and bounding techniques. Extensive experiments on both real and synthetic datasets verify the effectiveness and efficiency of the proposed model and algorithms.

  17. Asking well-built questions for evidence-based practice in augmentative and alternative communication. (United States)

    Schlosser, Ralf W; Koul, Rajinder; Costello, John


    Evidence-based practice (EBP) is increasingly being advocated as the preferred approach to practice in augmentative and alternative communication (AAC). The EBP process involves multiple steps. The asking of a well-built question is the first step in the quest for answers. At the same time it is also often the first stumbling block for practitioners. To facilitate the asking of well-built questions it may be helpful to follow a template. The most frequently used template is PICO, which stands for patient, intervention, comparison, and outcome [Richardson, W., Wilson, M., Nishikawa, J., & Hayward, R. (1995). The well-built clinical question: A key to evidence-based decisions. ACP Journal Club, 123, A12-A13]. In this article, we examine the suitability of the PICO template for AAC in terms of the representativeness of the components, and the appropriateness of its subcomponents, and their terminology. Based on this analysis, we propose the PESICO template, which stands for person, environments, stakeholders, intervention, comparison, and outcome. This template is then illustrated with examples representing a range of decision-making areas in AAC. Finally, directions for future research are provided. The reader will be able to: (1) appreciate the importance of asking well-built questions, (2) name the shortcomings of the PICO template, and (3) describe the components of the proposed PESICO template for asking well-built questions.

    Koegel, L K; Camarata, S M; Valdez-Menchaca, M; Koegel, R L


    We examined whether motivational procedures incorporated into teaching question-asking to children with autism, who lack verbal initiations, would result in generalization without additional teaching, prompting, or reinforcement in other settings. Specifically, we assessed whether such children could learn to use questions and whether the spontaneous use of question-asking would generalize across stimuli, settings, and people. All children learned to use questions in relation to items they had previously been unable to label and demonstrated generalization of spontaneous question-asking to new items and to their home environments with their mothers, with concomitant gains in expressive vocabulary. Results were discussed in terms of teaching response strategies, such as question-asking, to promote spontaneous child-initiated social interactions and expressive language development.

  5. Performance Evaluation of Frequent Subgraph Discovery Techniques

    Directory of Open Access Journals (Sweden)

    Saif Ur Rehman


    Full Text Available Due to rapid development of the Internet technology and new scientific advances, the number of applications that model the data as graphs increases, because graphs have highly expressive power to model a complicated structure. Graph mining is a well-explored area of research which is gaining popularity in the data mining community. A graph is a general model to represent data and has been used in many domains such as cheminformatics, web information management system, computer network, and bioinformatics, to name a few. In graph mining the frequent subgraph discovery is a challenging task. Frequent subgraph mining is concerned with discovery of those subgraphs from graph dataset which have frequent or multiple instances within the given graph dataset. In the literature a large number of frequent subgraph mining algorithms have been proposed; these included FSG, AGM, gSpan, CloseGraph, SPIN, Gaston, and Mofa. The objective of this research work is to perform quantitative comparison of the above listed techniques. The performances of these techniques have been evaluated through a number of experiments based on three different state-of-the-art graph datasets. This novel work will provide base for anyone who is working to design a new frequent subgraph discovery technique.

    We examine the bid-ask quotes offered by specialists (or dealers) who face indirect competition from other specialists who trade in related assets. In the context of a simple model where investors have mean variance preferences, we characterize the equilibrium bids and asks quoted by K specialists in N assets, where some specialists may control more than one asset. We compare the equilibrium spreads as the number (and factor structure) of the assets each specialist controls is varied. It is s...

  7. Text Classification Using Sentential Frequent Itemsets

    Institute of Scientific and Technical Information of China (English)

    Shi-Zhu Liu; He-Ping Hu


    Text classification techniques mostly rely on single term analysis of the document data set, while more concepts,especially the specific ones, are usually conveyed by set of terms. To achieve more accurate text classifier, more informative feature including frequent co-occurring words in the same sentence and their weights are particularly important in such scenarios. In this paper, we propose a novel approach using sentential frequent itemset, a concept comes from association rule mining, for text classification, which views a sentence rather than a document as a transaction, and uses a variable precision rough set based method to evaluate each sentential frequent itemset's contribution to the classification. Experiments over the Reuters and newsgroup corpus are carried out, which validate the practicability of the proposed system.

    Works cited in six forensic psychology journals published 2008-2010 were counted to identify the most frequently cited journals. The sample of works cited (N = 21,776) was not a definitive ranked list of important journals in forensic psychology, but was large enough to indicate high-impact journals. The list of frequently cited publications included more general psychiatry and psychology journals than titles specific to forensic psychology. The implications of the proportion of general versus specific titles for collections supporting research in forensic psychology were discussed.

    This paper investigates the effect of uncertainty on a single firm's pricing behaviour in a dynamic menu cost model that results in (S,s)-rules where the price is fixed inside a band. It will be demonstrated that even though the band of inaction widens in response to increased uncertainty......, the price may be changed more frequent in the short run, and in the long run it definitely will. Hence, observing frequent price changes is not necessarily inconsistent with a firm operating under menu costs. This paper relies on an article by Dixit (1991), (Review of Economic studies, 58, 141...

  11. The Value Of Enhanced Neo Surveys (United States)

    Harris, Alan W.


    NEO surveys have now achieved, more or less, the “Spaceguard Goal” of cataloging 90% of NEAs larger than 1 km in diameter, and thereby have reduced the short-term hazard from cosmic impacts by about an order of magnitude, from an actuarial estimate of 1,000 deaths per year (actually about a billion every million years, with very little in between), to about 100 deaths per year, with a shift toward smaller but more frequent events accounting for the remaining risk. It is fair to ask, then, what is the value of a next-generation accelerated survey to “retire” much of the remaining risk. The curve of completion of survey versus size of NEA is remarkably similar for any survey, ground or space based, visible light or thermal IR, so it is possible to integrate risk over all sizes, with a time variable curve of completion to evaluate the actuarial value of speeding up survey completion. I will present my latest estimate of NEA population and completion of surveys. From those I will estimate the “value” of accelerated surveys such as Pan-STARRS, LSST, or space-based surveys, versus continuing with current surveys. My tentative conclusion is that we may have already reached the point in terms of cost-benefit where accelerated surveys are not cost-effective in terms of reducing impact risk. If not yet, we soon will. On the other hand, the surveys, which find and catalog main-belt and other classes of small bodies as well as NEOs, have provided a gold mine of good science. The scientific value of continued or accelerated surveys needs to be emphasized as the impact risk is increasingly “retired.”

  18. Parents' Qualitative Perspectives on Child Asking for Fruit and Vegetables. (United States)

    Beltran, Alicia; O'Connor, Teresia M; Hughes, Sheryl O; Thompson, Debbe; Baranowski, Janice; Nicklas, Theresa A; Baranowski, Tom


    Children can influence the foods available at home, but some ways of approaching a parent may be better than others; and the best way may vary by type of parent. This study explored how parents with different parenting styles would best receive their 10 to 14 years old child asking for fruits and vegetables (FV). An online parenting style questionnaire was completed and follow-up qualitative telephone interviews assessed home food rules, child influence on home food availability, parents' preferences for being asked for food, and common barriers and reactions to their child's FV requests. Parents (n = 73) with a 10 to 14 years old child were grouped into authoritative, authoritarian, permissive, or uninvolved parenting style categories based on responses to questionnaires, and interviewed. Almost no differences in responses were detected by parenting style or ethnicity. Parents reported their children had a voice in what foods were purchased and available at home and were receptive to their child's asking for FV. The most important child asking characteristic was politeness, especially among authoritarian parents. Other important factors were asking in person, helping in the grocery store, writing requests on the grocery shopping list, and showing information they saw in the media. The barrier raising the most concern was FV cost, but FV quality and safety outside the home environment were also considerations.

  19. Understanding women's hesitancy to undergo less frequent cervical cancer screening. (United States)

    Gerend, Mary A; Shepherd, Melissa A; Kaltz, Emily A; Davis, Whitney J; Shepherd, Janet E


    Inappropriate cervical cancer screening (e.g., screening too often) can result in unnecessary medical procedures, treatment, and psychological distress. To balance the benefits and harms, cervical cancer screening guidelines were recently modified in favor of less frequent screening (i.e., every 3 to 5 years). This study investigated women's acceptance of less frequent cervical cancer screening and their primary concerns about extending the screening interval beyond one year. A national sample of 376 U.S. women ages 21-65 completed an online survey in 2014. Predictors of willingness to get a Pap test every 3 to 5 years were identified using logistic regression. We also examined perceived consequences of less frequent screening. Over two thirds were willing to undergo less frequent screening if it was recommended by their healthcare provider. Nevertheless, nearly 20% expressed discomfort with less frequent screening and 45% were either in opposition or unsure whether they would be comfortable replacing Pap testing with primary HPV testing. Women whose most recent Pap test was (vs. was not) within the past year and women who ever (vs. never) had an abnormal Pap test were less willing to extend the screening interval. Additionally, women who typically saw an obstetrician/gynecologist or nurse practitioner for their Pap test (vs. a family physician) were less accepting of the guidelines. Hesitancy about the longer screening interval appears to stem from concern about developing cancer between screenings. Findings contribute to the growing body of research on cancer overscreening and may inform interventions for improving adherence to cancer screening guidelines.

    Bayir, Murat Ali; Cosar, Ahmet; Fidan, Guven


    Web usage mining is a type of web mining, which exploits data mining techniques to discover valuable information from navigation behavior of World Wide Web users. As in classical data mining, data preparation and pattern discovery are the main issues in web usage mining. The first phase of web usage mining is the data processing phase, which includes the session reconstruction operation from server logs. Session reconstruction success directly affects the quality of the frequent patterns discovered in the next phase. In reactive web usage mining techniques, the source data is web server logs and the topology of the web pages served by the web server domain. Other kinds of information collected during the interactive browsing of web site by user, such as cookies or web logs containing similar information, are not used. The next phase of web usage mining is discovering frequent user navigation patterns. In this phase, pattern discovery methods are applied on the reconstructed sessions obtained in the first phas...

    Zaitsev, N


    Microstructure of market dynamics is studied through analysis of tick price data. Linear trend is introduced as a tool for such analysis. Trend arbitrage inequality is developed and tested. The inequality sets limiting relationship between trend, bid-ask spread, market reaction and average update frequency of price information. Average time of market reaction is measured from market data. This parameter is interpreted as a constant value of the stock exchange and is attributed to the latency of exchange reaction to actions of traders. This latency and cost of trade are shown to be the main limit of bid-ask spread. Data analysis also suggests some relationships between trend, bid-ask spread and average frequency of price update process.

    Seguin, Jade; Osmanlliu, Esli; Zhang, Xun; Clavel, Virginie; Eisman, Harley; Rodrigues, Robert; Oskoui, Maryam


    Emergency department (ED) crowding is associated with increased morbidity and mortality. Its etiology is multifactorial, and frequent ED use (defined as more or equal to five visits per year) is a major contributor to high patient volumes. Our primary objective is to characterize the frequent user population. Our secondary objective is to examine risk factors for frequent emergency use. We conducted a retrospective cohort study of pediatric emergency department (PED) visits at the Montreal Children's Hospital using the Système Informatique Urgence (SIURGE), electronic medical record database. We analysed the relation between patient's characteristics and the number of PED visits over a 1-year period following the index visit. Patients totalling 52,088 accounted for 94,155 visits. Of those, 2,474 (4.7%) patients had five and more recurrent visits and accounted for 16.6% (15,612 visits) of the total PED visits. Lower level of acuity at index visit (odds ratio [OR] 0.85) was associated with a lower number of recurrent visits. Lower socioeconomic status (social deprivation index OR 1.09, material deprivation index OR 1.08) was associated with a higher number of recurrent visits. Asthma (OR 1.57); infectious ear, nose, and sinus disorders (OR 1.33); and other respiratory disorders (OR 1.56) were independently associated with a higher incidence of a recurrent visit within the year following the first visit. Our study is the first Canadian study to assess risk factors of frequent pediatric emergency use. The identified risk factors and diagnoses highlight the need for future evidence-based, targeted innovative research evaluating strategies to minimize ED crowding, to improve health outcomes and to improve patient satisfaction.

  5. A New Algorithm for Mining Frequent Pattern

    Institute of Scientific and Technical Information of China (English)

    李力; 靳蕃


    Mining frequent pattern in transaction database, time-series databases, and many other kinds of databases have been studied popularly in data mining research. Most of the previous studies adopt Apriori-like candidate set generation-and-test approach. However, candidate set generation is very costly. Han J. proposed a novel algorithm FP-growth that could generate frequent pattern without candidate set. Based on the analysis of the algorithm FP-growth, this paper proposes a concept of equivalent FP-tree and proposes an improved algorithm, denoted as FP-growth*, which is much faster in speed, and easy to realize. FP-growth* adopts a modified structure of FP-tree and header table, and only generates a header table in each recursive operation and projects the tree to the original FP-tree. The two algorithms get the same frequent pattern set in the same transaction database, but the performance study on computer shows that the speed of the improved algorithm, FP-growth*, is at least two times as fast as that of FP-growth.

  7. Frequent video game players resist perceptual interference.

    Directory of Open Access Journals (Sweden)

    Aaron V Berard

    Full Text Available Playing certain types of video games for a long time can improve a wide range of mental processes, from visual acuity to cognitive control. Frequent gamers have also displayed generalized improvements in perceptual learning. In the Texture Discrimination Task (TDT, a widely used perceptual learning paradigm, participants report the orientation of a target embedded in a field of lines and demonstrate robust over-night improvement. However, changing the orientation of the background lines midway through TDT training interferes with overnight improvements in overall performance on TDT. Interestingly, prior research has suggested that this effect will not occur if a one-hour break is allowed in between the changes. These results have suggested that after training is over, it may take some time for learning to become stabilized and resilient against interference. Here, we tested whether frequent gamers have faster stabilization of perceptual learning compared to non-gamers and examined the effect of daily video game playing on interference of training of TDT with one background orientation on perceptual learning of TDT with a different background orientation. As a result, we found that non-gamers showed overnight performance improvement only on one background orientation, replicating previous results with the interference in TDT. In contrast, frequent gamers demonstrated overnight improvements in performance with both background orientations, suggesting that they are better able to overcome interference in perceptual learning. This resistance to interference suggests that video game playing not only enhances the amplitude and speed of perceptual learning but also leads to faster and/or more robust stabilization of perceptual learning.

  11. Question asking by family caregivers in hospice interdisciplinary team meetings. (United States)

    Wittenberg-Lyles, Elaine; Oliver, Debra Parker; Demiris, George; Washington, Karla T; Regehr, Kelly; Wilder, Heidi M


    This article reports findings from a pilot study that enabled family caregivers to use videophone technology to participate in hospice interdisciplinary team meetings. The goal of the study was to ascertain which issues were important to caregivers and the hospice team. A qualitative content analysis of video-recorded team meetings between team members and caregivers was conducted. In a sample of 12 caregivers in 36 discussions, caregivers asked a total of 137 questions, with the majority being Yes/No questions (45.1%), primarily used to seek clarification (19.6%). Hospice staff asked 396 questions, with the majority consisting of Yes/No questions (66.5%), mainly used to ask about the overall condition of the patient (22.2%). Data from this study suggest that when given the opportunity to participate in hospice team meetings, caregivers will ask questions of hospice staff. In addition, in light of prior research, this study's findings suggest that caregivers may have questions that go unaddressed, specifically regarding pain and medication.

  18. Frequent external focus feedback enhances motor learning

    Directory of Open Access Journals (Sweden)

    Gabriele eWulf


    Full Text Available The present study examined the hypothesis that feedback inducing an external focus of attention enhances motor learning if it is provided frequently (i.e., 100% rather than less frequently. Children (10-12 year olds practiced a soccer throw-in task and were provided feedback about movement form. The feedback statements, provided either after every (100% or every third (33% practice trial, were similar in content but induced either an internal focus (body-movement related or external focus (movement-effect related. The results demonstrated that learning of the movement form was enhanced by external-focus feedback after every trial (100% relative to external-focus feedback after every third trial (33% or internal-focus feedback (100%, 33%, as demonstrated by immediate and delayed transfer tests without feedback. There was no difference between the two internal-focus feedback groups. These findings indicate that the attentional focus induced by feedback is an important factor in determining the effectiveness of different feedback frequencies. We argue that the informational properties of feedback cannot sufficiently account for these and related findings, and suggest that the attentional role of feedback be given greater consideration in future studies.

  19. Frequent MAGE mutations in human melanoma.

    Directory of Open Access Journals (Sweden)

    Otavia L Caballero

    Full Text Available BACKGROUND: Cancer/testis (CT genes are expressed only in the germ line and certain tumors and are most frequently located on the X-chromosome (the CT-X genes. Amongst the best studied CT-X genes are those encoding several MAGE protein families. The function of MAGE proteins is not well understood, but several have been shown to potentially influence the tumorigenic phenotype. METHODOLOGY/PRINCIPAL FINDINGS: We undertook a mutational analysis of coding regions of four CT-X MAGE genes, MAGEA1, MAGEA4, MAGEC1, MAGEC2 and the ubiquitously expressed MAGEE1 in human melanoma samples. We first examined cell lines established from tumors and matching blood samples from 27 melanoma patients. We found that melanoma cell lines from 37% of patients contained at least one mutated MAGE gene. The frequency of mutations in the coding regions of individual MAGE genes varied from 3.7% for MAGEA1 and MAGEA4 to 14.8% for MAGEC2. We also examined 111 fresh melanoma samples collected from 86 patients. In this case, samples from 32% of the patients exhibited mutations in one or more MAGE genes with the frequency of mutations in individual MAGE genes ranging from 6% in MAGEA1 to 16% in MAGEC1. SIGNIFICANCE: These results demonstrate for the first time that the MAGE gene family is frequently mutated in melanoma.

  20. The Role Of Gender In Asking Questions At Cool Stars 18 And 19 (United States)

    Schmidt, Sarah J.; Douglas, Stephanie; Gosnell, Natalie M.; Muirhead, Philip S.; Booth, Rachel S.; Davenport, James R. A.; Mace, Gregory N.


    We examine the gender balance of the 18th and 19th meetings of the Cambridge Workshop on Cool Stellar Systems and the Sun (CS18 and CS19). The percent of female attendees at both meetings (31% at CS18 and 37% at CS19) was higher than the percent of women in the American Astronomical Society (25%) and the International Astronomical Union (18%). The representation of women in Cool Stars as SOC members, invited speakers, and contributed speakers was similar to or exceeded the percent of women attending the meetings. We requested that conference attendees assist in a project to collect data on the gender of astronomers asking questions after talks. Using this data, we found that men were over-represented (and women were under-represented) in the question sessions after each talk. Men asked 79% of the questions at CS18 and 75% of the questions at CS19, but were 69% and 63% of the attendees respectively. Contrary to findings from previous conferences, we did not find that the gender balance of questions was strongly affected by the session chair gender, the speaker gender, or the length of the question period. We also found that female and male speakers were asked a comparable number of questions after each talk. The contrast of these results from previous incarnations of the gender questions survey indicate that more data would be useful in understanding the factors that contribute to the gender balance of question askers. We include a preliminary set of recommendations based on this and other work on related topics, but also advocate for additional research on the demographics of conference participants. Additional data on the intersection of gender with race, seniority, sexual orientation, ability and other marginalized identities is necessary to fully address the role of gender in asking questions at conferences.

    Full Text Available Tanweer Karim, Margaret Topno, Vinod Sharma, Raymond Picardo, Ankur HastirSurgery, MGM Medical College, Kamothe, Navi Mumbai, IndiaAbstract: Bladder injuries are very common in patients who have had road traffic accidents. The method of diagnosis and management of such injuries is well established and accepted. However, trauma to the bladder can be associated with other life-threatening injuries which are frequently missed, and often diagnosed during laparotomy for other reasons. The aim of this study was to diagnose bladder injury in polytrauma patients as early as possible, taking into consideration the fact that these patients are hemodynamically unstable and require rapid evaluation and management. In order to achieve our objective, we used bedside sonography with retrograde instillation of normal saline to diagnose bladder injury in addition to use of the conventional retrograde cystogram.Keywords: bladder injury, bladder rupture, retrograde cystogram

  2. LGM: Mining Frequent Subgraphs from Linear Graphs

    CERN Document Server

    Tabei, Yasuo; Hirose, Shuichi; Tsuda, Koji


    A linear graph is a graph whose vertices are totally ordered. Biological and linguistic sequences with interactions among symbols are naturally represented as linear graphs. Examples include protein contact maps, RNA secondary structures and predicate-argument structures. Our algorithm, linear graph miner (LGM), leverages the vertex order for efficient enumeration of frequent subgraphs. Based on the reverse search principle, the pattern space is systematically traversed without expensive duplication checking. Disconnected subgraph patterns are particularly important in linear graphs due to their sequential nature. Unlike conventional graph mining algorithms detecting connected patterns only, LGM can detect disconnected patterns as well. The utility and efficiency of LGM are demonstrated in experiments on protein contact maps.

  3. Frequent activation of EGFR in advanced chordomas

    Directory of Open Access Journals (Sweden)

    Dewaele Barbara


    Full Text Available Abstract Background Chordomas are rare neoplasms, arising from notochordal remnants in the midline skeletal axis, for which the current treatment is limited to surgery and radiotherapy. Recent reports suggest that receptor tyrosine kinases (RTK might be essential for the survival or proliferation of chordoma cells, providing a rationale for RTK targeted therapy. Nevertheless, the reported data are conflicting, most likely due to the assorted tumor specimens used for the studies and the heterogeneous methodological approaches. In the present study, we performed a comprehensive characterization of this rare entity using a wide range of assays in search for relevant therapeutic targets. Methods Histopathological features of 42 chordoma specimens, 21 primary and 21 advanced, were assessed by immunohistochemistry and fluorescent in situ hybridization (FISH using PDGFRB, CSF1R, and EGFR probes. Twenty-two of these cases, for which frozen material was available (nine primary and 13 advanced tumors, were selectively analyzed using the whole-genome 4.3 K TK-CGH-array, phospho-kinase antibody array or Western immunoblotting. The study was supplemented by direct sequencing of KIT, PDGFRB, CSF1R and EGFR. Results We demonstrated that EGFR is frequently and the most significantly activated RTK in chordomas. Furthermore, concurrent to EGFR activation, the tumors commonly reveal co-activation of alternative RTK. The consistent activation of AKT, the frequent loss of the tumor suppressor PTEN allele, the recurrent activation of upstream RTK and of downstream effectors like p70S6K and mTOR, all indicate the PI3K/AKT pathway as an important mediator of transformation in chordomas. Conclusions Given the complexity of the signaling in chordomas, combined treatment regimens targeting multiple RTK and downstream effectors are likely to be the most effective in these tumors. Personalized therapy with careful selection of the patients, based on the molecular profile of

  9. NCL Disorders: Frequent Causes of Childhood Dementia

    Directory of Open Access Journals (Sweden)



    Full Text Available Dementia in children or young adults is most frequently caused by neuronal ceroidlipofuscinoses (NCL, a group of incurable lysosomal storage disorders linked by the accumulation of a characteristic intracellular storage material and progressive clinical deterioration, usually in combination with visual loss, epilepsy, and motor decline. The clinical characteristics can vary and the age at disease onset ranges from birth to over 30 years. Diagnosis of an NCL is difficult because of genetic heterogeneity with14 NCL forms (CLN1- CLN14 identified and a high phenotype variability. A new classification of the disorders is based on the affected gene and the age at disease onset and allows a precise and practicable delineation of every NCL disease. We present a clear diagnostic algorithm to identify each NCL form. A precise diagnosis is essential for genetic counseling of affected families and for optimizing palliative care. As patient management profits from recognizing characteristic complications, care supported by a specialized team of NCL clinicians is recommended. The development of curative therapies remains difficult as the underlying pathophysiological mechanism remains unclear for all NCL forms.

  10. Most frequent calf diseases in industrial breeding

    Directory of Open Access Journals (Sweden)

    Lazić Sava


    Full Text Available It is possible to conduct an analysis of the incidence of viral diseases in calves if these diseases are divided into two basic groups. One group comprises diseases of respiratory organs which are manifested by symptoms of a respiratory syndrome, and the second group comprises diseases of digestive tract organs in the form of a gastrointestinal syndrome. It is considered that viruses have the dominant role in the complex etiology of the respiratory syndrome, primarily the IBR virus or the Bovine Herpes Virus-1 (BHV-1, followed by the parainfluenza 3 virus (RSV, the Bovine Viral Diahrrea Virus (BVDV, the bovine Respiratory Syncytial Virus (RSV, but also other viruses, such as adenoviruses, rhinoviruses, coronaviruses, can also influence the appearance of the respiratory syndrome. The respiratory syndrome is rarely caused by a single viral agent, but most frequently by mixed viruses, but also by bacterial infections. Mixed viral infections often have a lethal outcome. Investigations of the etiology of the gastrointestinal syndrome so far indicate that, in addition to bacteria, viruses can also be a significant etiological factor. Rotaviruses, coronaviruses, adenoviruses parvoviruses, herpesviruses (the IBR virus, pestiviruses (BVDV, can be the causes of a gastrointestinal syndrome. It is believed that viruses can be the cause in about 10% cases in the ethiopathogenesis of this syndrome. The paper describes the etiopathogenesis of calf diseases of viral etiology which are most often found in the local conditions of industrial breeding of calves.

    Directory of Open Access Journals (Sweden)



    Full Text Available The aim of this study is to describe the status and evolution of forest management in Romania in terms of forest regime, as well as to highlight the most frequent problems and common expectations of forest district managers. Underlying the presented results are an analysis of the compiled statistical indicators used in Romanian forestry and the outcome of a sociological survey conducted on a sample of 345 forest district managers. In early 2013, over 4.4 million hectares of state, public and private forest land were administered by state and experimental forest districts, and over 1.7 million hectares of forest land, other than state-owned, by private forest districts. Note that approximately 0.36 million hectares (over 5% of Romania’s forest area are not in the care of specialized units, contrary to the legal provisions. The most frequent problems faced by forest district managers arise in relation to the owners of forests or are caused by illegal logging. This study is a contribution to making the concrete problems faced by foresters and especially the structure and ownership related characteristics of forestland the driving force of legislative changes in the forestry sector.

  13. Problem neurology residents: a national survey. (United States)

    Tabby, David S; Majeed, Muhammed H; Schwartzman, Robert J


    Problem residents are found across most medical specialties at a prevalence of about 10%. This study was designed to explore the prevalence and causes of problem neurology residents and to compare neurology programs' responses and outcomes. Directors of 126 US neurology residency programs were sent an electronic survey. We collected data on demographics, first and all "identifiers" of problem residents, and year of training in which the problem was found. We asked about observable signs, etiology, and who performed remediation. We asked what resources were used and what outcomes occurred. Ninety-five program directors completed surveys (75% response rate). Almost all neurology programs have problem residents (81%). Age, sex, marital status, being a US native, or attending a US medical school had no effect on problem status. Being a parent carried a lower likelihood of problems (32%). Most commonly the problem is acted on during the first year of training. Faculty members without defined educational roles were the most frequent first identifiers. Program directors were the most common remediators. The most common remediation techniques were increasing supervision and assigning a faculty mentor. Graduate medical education office and psychiatric or psychological counseling services were most often used. Eleven percent of problem residents required a program for impaired physicians and 14% required a leave of absence. Sixteen percent were dismissed from their programs. The prevalence of problem residents in neurology is similar to other disciplines, and various resources are available to remediate them.

[Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Lopez, Leon [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)


    This was prepared for the business process improvement presentation to the Department of Energy. Los Alamos National Laboratory provides a single point of contact, the AskIT Service Desk, to address issues that impact customer productivity. At the most basic level, what customers want is for their calls to be received, to get a response from a knowledgeable analyst, and to have their issues resolved and their requests fulfilled. Providing a centralized, single point of contact service desk makes initiating technical or business support simple for the customer and improves the odds of immediately resolving the issue or correctly escalating the request to the next support level when necessary. Fulfilling customer requests through automated workflow also improves customer productivity and reduces costs. Finally, customers should be provided the option to solve their own problems through easy access to self-help resources such as frequently asked questions (FAQs) and how-to guides. To accomplish this, everyone who provides and supports services must understand how these processes and functions work together. Service providers and those who support services must “speak the same language” and share common objectives. The Associate Directorate for Business Innovation (ADBI) began the journey to improve services by selecting a known service delivery framework (Information Technology Infrastructure Library, or ITIL). From this framework, components that contribute significant business value were selected.

    Acetaminophen (APAP) overdose is the most frequent cause of drug-induced liver failure in the world. Hepatic c-jun NH2-terminal protein kinase (JNK) activation is thought to be a consequence of oxidative stress produced during APAP metabolism. Activation of JNK signals causes hepatocellular damage with necrotic and apoptotic cell death. Here we found that APAP caused a feedback increase in plasma adenosine 5′-monophsphate (5′-AMP). We demonstrated that co-administration of APAP and 5′-AMP significantly ameliorated APAP-induced hepatotoxicity in mice, without influences on APAP metabolism and its analgesic function. The mechanism of protection by 5′-AMP was through inhibiting APAP-induced activation of JNK, and attenuating downstream c-jun and c-fos gene expression. This was triggered by attenuating apoptosis signal-regulated kinase 1(ASK1) methylation and increasing ubiquitination-mediated ASK1 protein degradation. Our findings indicate that replacing the current APAP with a safe and functional APAP/5′-AMP formulation could prevent APAP-induced hepatotoxicity. PMID:28031524

  16. Viewing Asking for Leave from a Cultural Perspective

    Institute of Scientific and Technical Information of China (English)



    This thesis aims at investigating what the discourse patterns are in the asking-for-leave notes written by Chinese stu⁃dents and native English speakers respectively and what excuses are given by Chinese students and native English speakers. Role play and retrospective interview were employed as research methords. The results show that the Chinese students all use an induc⁃tive pattern, while all native English speakers write the note in a deductive way. Besides, the excuses presented by the two kinds of subjects are different due to their different cultural background.

  17. Clinton asks court to rule against assisted suicide. (United States)


    The U.S. Supreme Court has been urged by the Clinton Administration to overturn two appeals court rulings that bar States from enforcing laws that prohibit doctor-assisted suicide. Solicitor General Walter Dellinger asked the court to reverse rulings by the 2nd and 9th U.S. Circuit Court of Appeals blocking New York and Washington States from arresting doctors who hasten the death of patients. In both cases, the plaintiff included people with AIDS and their caregivers. President Clinton previously stated that he opposes euthanasia. AIDS policy advocates generally support legalizing assisted suicide and were disappointed in the administration's involvement in these cases.

  19. DPSK-3ASK transmission optimization by adapting modulation levels (United States)

    Eiselt, Michael H.; Teipen, Brian T.


    For metro and regional 100-Gbps transmission, a transparent channel reach of 500-600 km is required and a 100-GHz channel grid is typically used. For these applications, a cost effective modulation format is introduced which can make use of electronic components designed for the already established 40-Gbps market, bypassing the requirements for novel electronic developments and therefore reducing the component cost. With this DPSK-3ASK modulation format, five information bits are transmitted in two consecutive symbols, leading to a symbol rate of 45 Gbaud, including overhead for framing and FEC. To minimize hardware requirements and to create a cost-effective solution, a single Mach-Zehnder modulator can be used to create the optical DPSK-3ASK signal after combining the phase and amplitude modulation signals into a 6-level modulator drive voltage. In this paper, it is demonstrated by numerical simulations that these voltage levels can be modified to adapt to varying signal distortions and thereby yield improved transmission performance. It is shown that by dynamically modifying the modulation levels based on the channel performance, dynamic signal impairments such as the non-linear effects from varying power levels, changes in chromatic dispersion, or varying PMD levels can be mitigated. Error-free performance (with FEC) can be obtained with 24 dB OSNR and 7ps DGD for a 112-Gbps (45-Gbaud) optical signal.

  20. Mindless processing of requests? Don't ask twice. (United States)

    Slugoski, B R


    This study examines the mindlessness hypothesis and its associated compliance-gaining paradigm from the perspective of politeness theory. The main prediction of politeness theory, which is not taken into account in the mindlessness literature, is that the perceived magnitude of an imposition is a function not only of the size of favour asked but also of the framing of the request itself. A confederate asked students studying in the library for either one or 10 sheets of paper using appropriate variations of Langer et al.'s three request types: no reason, placebic reason and real reason. Students then completed a questionnaire to determine: (a) how large the imposition on them had been; (b) their verbatim memories for the requests; and (c) self-reported compliance with the requests. In order to examine the effect of reflective thought on subjects' judgements and recall, this questionnaire was completed either immediately following compliance/non-compliance or three minutes later. The analyses established that the perceived imposition is influenced jointly by the actual imposition, the type of request and the time of judgement. Further, contrary to some previous research, the recall memory data provide support for a strong version of the mindlessness hypothesis, as well as new evidence for the reconstructive character of conversation memory. It is concluded that politeness theory describes a powerful heuristic that people use when processing requests.

  1. What do Americans know about inequality? It depends on how you ask them

    Directory of Open Access Journals (Sweden)

    Kimmo Eriksson


    Full Text Available A recent survey of inequality (Norton and Ariely, Perspectives on Psychological Science, 6, 9-12 asked respondents to indicate what percent of the nation's total wealth is---and should be---controlled by richer and poorer quintiles of the U.S. population. We show that such measures lead to powerful anchoring effects that account for the otherwise remarkable findings that respondents reported perceiving, and desiring, extremely low inequality in wealth. We show that the same anchoring effects occur in other domains, namely web page popularity and school teacher salaries. We introduce logically equivalent questions about average levels of inequality that lead to more accurate responses. Finally, when we made respondents aware of the logical connection between the two measures, the majority said that typical responses to the average measures, indicating higher levels of inequality, better reflected their actual perceptions and preferences than did typical responses to percent measures.

  2. Merely asking the customer to recommend has an impact on word-of-mouth activity

    DEFF Research Database (Denmark)

    Mattsson, Jan; Söderlund, Magnus


    This paper examines if a mere request to a customer – within the frame of a service encounter – to engage in word-of-mouth (WOM) would have an impact on the customer's subsequent WOM activity. Although previous studies have not examined this issue, theoretical arguments do exist. And they point...... in different directions; some suggest a positive impact, while others suggest a negative impact. To explore the issue empirically, we carried out two studies (one survey-based study and one experiment). Both generated the same result: they indicate that merely asking customers to engage in WOM has a positive...... impact on customers' WOM activity. In addition, we found that receiving the request was not negatively associated with the customers' overall evaluations, such as customer satisfaction, which indicates that the potential for negative consequences of making the request seems to be low....

  3. Ask a Busy Person: Attentional Myopia and Helping. (United States)

    Wallaert, Matthew; Ward, Andrew; Mann, Traci


    According to an oft-quoted piece of folk wisdom, if one wants something accomplished, the best person to ask is a busy person. We tested a version of this proposition in two studies. Study 1 exposed participants to a helping request in which cues promoting the relevant behavior were made more salient than those inhibiting it. Study 2 featured a request in which inhibiting cues were made more salient than cues promoting the behavior. In both studies, participants who were "busied" by high cognitive load showed more influence of the dominant behavioral pressure than did participants under minimal load. The results suggest that busy people can respond more to a helping appeal, but only when cues facilitating helping are more salient than those discouraging it.

  4. Human-Assisted Graph Search: It's Okay to Ask Questions

    CERN Document Server

    Parameswaran, Aditya; Garcia-Molina, Hector; Polyzotis, Neoklis; Widom, Jennifer


    We consider the problem of human-assisted graph search: given a directed acyclic graph with some (unknown) target node(s), we consider the problem of finding the target node(s) by asking an omniscient human questions of the form "Is there a target node that is reachable from the current node?". This general problem has applications in many domains that can utilize human intelligence, including curation of hierarchies, debugging workflows, image segmentation and categorization, interactive search and filter synthesis. To our knowledge, this work provides the first formal algorithmic study of the optimization of human computation for this problem. We study various dimensions of the problem space, providing algorithms and complexity results. Our framework and algorithms can be used in the design of an optimizer for crowd-sourcing platforms such as Mechanical Turk.

  5. Florida court asked to decide legality of limiting suits. (United States)


    The state Supreme Court of Florida will rule on the legitimacy of a statute that restricts the ability of a plaintiff to sue for damages arising from HIV-contaminated blood transfusion. Under the malpractice law, patients have 4 years from the time of injury to file suit. In most HIV and AIDS cases, however, symptoms do not appear within the 4-year period. The Broward County Circuit Court recently dismissed a contaminated blood transfusion suit based on the expiration of the 4-year statute of repose. The Court of Appeals held the trial judge's application of the law correct, but found the statute uniquely unfair and harsh in HIV/AIDS cases. The State Supreme Court has been asked to rule on the issue.

  6. Three questions you need to ask about your brand. (United States)

    Keller, Kevin Lane; Sternthal, Brian; Tybout, Alice


    Traditionally, the people responsible for positioning brands have concentrated on the differences that set each brand apart from the competition. But emphasizing differences isn't enough to sustain a brand against competitors. Managers should also consider the frame of reference within which the brand works and the features the brand shares with other products. Asking three questions about your brand can help: HAVE WE ESTABLISHED A FRAME?: A frame of reference--for Coke, it might be as narrow as other colas or as broad as all thirst-quenching drinks--signals to consumers the goal they can expect to achieve by using a brand. Brand managers need to pay close attention to this issue, in some cases expanding their focus in order to preempt the competition. ARE WE LEVERAGING OUR POINTS OF PARITY?: Certain points of parity must be met if consumers are to perceive your product as a legitimate player within its frame of reference. For instance, consumers might not consider a bank truly a bank unless it offers checking and savings plans. ARE THE POINTS OF DIFFERENCE COMPELLING?: A distinguishing characteristic that consumers find both relevant and believable can become a strong, favorable, unique brand association, capable of distinguishing the brand from others in the same frame of reference. Frames of reference, points of parity, and points of difference are moving targets. Maytag isn't the only dependable brand of appliance, Tide isn't the only detergent with whitening power, and BMWs aren't the only cars on the road with superior handling. The key questions you need to ask about your brand may not change, but their context certainly will. The saviest brand positioners are also the most vigilant.

    PENG Dun-lu; QIU Yang


    It is nontrivial to maintain such discovered frequent query patterns in real XML-DBMS because the transaction database of queries may allow frequent updates and such updates may not only invalidate some existing frequent query patterns but also generate some new frequent query patterns.In this paper, two incremental updating algorithms, FUXQMiner and FUFXQMiner, are proposed for efficient maintenance of discovered frequent query patterns and generation the new frequent query patterns when new XML queries are added into the database.Experimental results from our implementation show that the proposed algorithms have good performance.

  9. Smartphone gaming and frequent use pattern associated with smartphone addiction (United States)

    Liu, Chun-Hao; Lin, Sheng-Hsuan; Pan, Yuan-Chien; Lin, Yu-Hsuan


    Abstract The aim of this study was to investigate the risk factors of smartphone addiction in high school students. A total of 880 adolescents were recruited from a vocational high school in Taiwan in January 2014 to complete a set of questionnaires, including the 10-item Smartphone Addiction Inventory, Chen Internet Addiction Scale, and a survey of content and patterns of personal smartphone use. Of those recruited, 689 students (646 male) aged 14 to 21 and who owned a smartphone completed the questionnaire. Multiple linear regression models were used to determine the variables associated with smartphone addiction. Smartphone gaming and frequent smartphone use were associated with smartphone addiction. Furthermore, both the smartphone gaming-predominant and gaming with multiple-applications groups showed a similar association with smartphone addiction. Gender, duration of owning a smartphone, and substance use were not associated with smartphone addiction. Our findings suggest that smartphone use patterns should be part of specific measures to prevent and intervene in cases of excessive smartphone use. PMID:27428191

  11. Frequent visitors to psychiatric emergency services: staff attitudes and temporal patterns. (United States)

    Arfken, Cynthia; Zeman, Lori Lackman; Yeager, Lindsay; Mischel, Edward; Amirsadri, Alireza


    Providing quality psychiatric emergency services is becoming more difficult as utilization rates soar, especially by individuals who are frequent visitors. To address this issue, a staff survey and analysis of admission patterns were conducted. Staff were more likely to believe that frequent visitors sought care because they had difficulty accessing alternative services, had basic needs unmet, were substance abusers, wanted inpatient admission, and were noncompliant with treatment plans. The 1999 temporal admission pattern documented that frequent visitors' admissions were higher during the first week of the month and inclement weather. Surprisingly, the infrequent visitors' admissions also were higher during the first week of the month. Together, these findings suggest that, in this urban location, frequent visitors are disadvantaged individuals lacking support and alternative treatment settings who use psychiatric emergency services to meet basic needs.

  15. A national survey of family physicians: perspectives on collaboration with marriage and family therapists. (United States)

    Clark, Rebecca E; Linville, Deanna; Rosen, Karen H


    Recognizing the fit between family medicine and marriage and family therapy (MFT), members of both fields have made significant advances in collaborative health research and practice. To add to this work, we surveyed a nationwide random sample of 240 family physicians (FPs) and asked about their perspectives and experiences of collaboration with MFTs. We found that FPs frequently perceive a need for their patients to receive MFT-related care, but their referral to and collaboration with MFTs were limited. Through responses to an open-ended question, we gained valuable information as to how MFTs could more effectively initiate collaboration with FPs.

  16. AskIT Service Desk Support Value Model

    Ashcraft, Phillip Lynn [Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Cummings, Susan M. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Fogle, Blythe G. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Valdez, Christopher D. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)


    The value model discussed herein provides an accurate and simple calculation of the funding required to adequately staff the AskIT Service Desk (SD).  The model is incremental – only technical labor cost is considered.  All other costs, such as management, equipment, buildings, HVAC, and training are considered common elements of providing any labor related IT Service. Depending on the amount of productivity loss and the number of hours the defect was unresolved, the value of resolving work from the SD is unquestionably an economic winner; the average cost of $16 per SD resolution can commonly translate to cost avoidance exceeding well over $100. Attempting to extract too much from the SD will likely create a significant downside. The analysis used to develop the value model indicates that the utilization of the SD is very high (approximately 90%).  As a benchmark, consider a comment from a manager at Vitalyst (a commercial IT service desk) that their utilization target is approximately 60%.  While high SD utilization is impressive, over the long term it is likely to cause unwanted consequences to staff such as higher turnover, illness, or burnout.  A better solution is to staff the SD so that analysts have time to improve skills through training, develop knowledge, improve processes, collaborate with peers, and improve customer relationship skills.

  17. Refugees' advice to physicians: how to ask about mental health. (United States)

    Shannon, Patricia J


    About 45.2 million people were displaced from their homes in 2012 due to persecution, political conflict, generalized violence and human rights violations. Refugees who endure violence are at increased risk of developing chronic psychiatric disorders such as posttraumatic stress disorder and major depression. The primary care visit may be the first opportunity to detect the devastating psychological effects of trauma. Physicians and refugees have identified communication barriers that inhibit discussions about mental health. In this study, refugees offer advice to physicians about how to assess the mental health effects of trauma. Ethnocultural methodology informed 13 focus groups with 111 refugees from Burma, Bhutan, Somali and Ethiopia. Refugees responded to questions concerning how physicians should ask about mental health in acceptable ways. Focus groups were recorded, transcribed and analyzed using thematic categorization informed by Spradley's Developmental Research Sequence. Refugees recommended that physicians should take the time to make refugees comfortable, initiate direct conversations about mental health, inquire about the historical context of symptoms and provide psychoeducation about mental health and healing. Physicians may require specialized training to learn how to initiate conversations about mental health and provide direct education and appropriate mental health referrals in a brief medical appointment. To assist with making appropriate referrals, physicians may also benefit from education about evidence-based practices for treating symptoms of refugee trauma. © The Author 2014.

  1. Perceived quality of social relations and frequent drunkenness: a cross-sectional study of Spanish adolescents. (United States)

    Kjærulff, Thora M; Rivera, Francisco; Jiménez-Iglesias, Antonia; Moreno, Carmen


    The aim of the study was to examine, for female and male students separately, whether perceived quality of relationships with peers and parents and relations in school predict self-reported frequent drunkenness among Spanish adolescents. The Spanish data from the Health Behaviour in School-aged Children Study (HBSC) 2010 survey were used including 1177 female and 1126 male students aged between 15 and 16 years. For both genders, students reporting low school satisfaction had increased odds of frequent drunkenness. Among females, low and medium levels of classmate support were associated with decreased odds of frequent drunkenness, whereas low perceived maternal knowledge as well as medium and low satisfaction with the family increased odds of being frequently drunk. The proportion of male students reporting medium satisfaction with friendships had significantly lower odds of frequent drunkenness compared with those with high level of satisfaction with friendships. We found different associations between perceived quality of social relations and frequent drunkenness among male and female students. Results showed that social relations seemed to better predictors of frequent drunkenness among female than male students and that other factors than social relations may contribute to explain excessive alcohol use among Spanish adolescents. © The Author 2014.

  2. [Child psychiatric documentation in child visitation and custody disputes--results of a survey]. (United States)

    Andritzky, Walter


    In the last decade, increasing divorce rates, a joint custodial concept, and a deficient legal situation of non-married fathers have been involuntarily provoking cases of a parent with child custody alienating that child in order to exclude the other parent from visitations and educational participation. Medical certificates are frequently of fateful importance in child custody litigation. In an mail survey conduced in six German cities, N = 133 child psychiatrists were asked about the frequency in which they issue such certificates, what certificates contained, what recommendations were made, and where possible the reasons why the other parent was not included in the diagnostic process. According to the results 74.4% of those surveyed were asked to issue such medical certificates at least once in the year prior to the survey; 42% of the psychiatrists stating that the other parent never or only sometimes participated. The symptoms most frequently certified were behavioural disorders (46%), aggression (34%), problems in school/ADD (28%), anxiety (26%), bed-wetting (23%), depression (21%), and psychosomatic reactions (20%). Outlining the characteristics of alienated children and of alienating parents, of "natural" and of "induced" stress-symptoms in children after parental separation, the article provides physicians and institutions of the health system with support to prevent medical certificates being abused in child custody litigation. Some fundamental guidelines are presented as to what aspects and should be explored and which persons referred to before certificates are issued to parents, social workers or judges of family law courts.

    To describe the evolution of health interview surveys in Spain (as of 01/01/2012), whether national or regional, its main characteristics and methodology, and in the case of general health surveys (GHIS), its contents. An adapted version of Eurostat quality control template European Health Interview Survey Technical and Methodological Report was filled in by those responsible for GHIS in each region (autonomous communities) and at the national level. The first part (11 questions) gathers general information about health surveys, both GHIS and surveys targeted to specific populations or health problems (SHIS). The second part (109 questions) asks about methodological characteristics of most recent GHIS. 1) regional or supra-regional scope; 2) for the second part, GHIS currently active series. Quality control was performed using double data entry and validated by informants.100 HIS were identified. 16 were GHIS and 84 SHIS. 32 (38%) of the latter were national and 52 (62%) regional. Nutrition 21 (25%), drug use 10 (12%), opinion polls 7 (9%) and dental health 7 (9%) were the most frequent topics in SHIS. Highest GHIS density was reached after year 2000, with several surveys on field at a time (mode=3). 11 GHIS (2 national, 9 regional) met inclusion criteria for the second part. All complied with general quality benchmarks. Few differences were observed in content.GHIS show more similarities than differences in objectives, methods and content. Rationalization and harmonization are needed. Physical activity, alcohol consumption, quality of life and mental health instruments are not yet consensual. Valid and comparable data are required on health status and its determinants to inform health policy.

  5. Physics of Toys: The Joy of Asking Questions (United States)

    Taylor, Beverley


    Children are natural scientists. They ask questions, they observe, they try things to see what happens. Often school-based science does little to nurture the young scientist and, in fact, may do just the opposite with thick textbooks, fact heavy lessons, and too many equations. The exploration of common toys produces deep learning by emphasizing concepts and connections before formal definitions and mathematics. It also connects the classroom to the familiar world outside of school and gets students writing and talking about physics ideas. At the university level, investigating what toys do and how they do it can be a challenging application of undergraduate physics from the introductory course up through senior mechanics. Toys provide an ideal system for the kind of open-ended inquiry that introduces students to what scientists really do. They can pose their own questions, explore the behavior of the system sufficiently to create a hypothesis, use their theoretical knowledge to make a simplified model of the system and predict an outcome, design an experiment, discover that the real world is messy, think about what they haven't taken into account with their simple model and try to improve it. I have spent close to 30 years thinking about how to use toys to enhance physics education from 4th grade through college. In the process I have collected hundreds of toys the majority of which relate to mechanics, but also to sound, light, electricity and magnetism. I will discuss the pedagogical reasons for using toys in physics education and the many different ways to use them from demonstrations to laboratory experiments to discussion starters as well as how it is possible to use the same toy with many different age levels by approaching the analysis differently. I will share a number of my favorite toys, but focus particularly on those related to energy concepts.

  7. Ad hoc distributed mutual exclusion algorithm based on token-asking

    Institute of Scientific and Technical Information of China (English)

    Wang Zheng; Liu Xin song; Li Mei'an


    The solution of distributed mutual exclusion is difficult in Ad hoc networks owing to dynamic topologies and mobility.Based on the analysis of the properties of Ad hoc networks and the disadvantages of the traditional algorithms, an improved Ad hoc system model was given and a novel algorithm was presented as AHDME (Ad Hoc Distributed Mutual Exclusion); it was based on the token-asking algorithms.It utilized broadcast to search for the token and to decrease the message complexity of multi-hop Ad hoc networks.Lamport's timestamp was improved to ensure the time sequence and to prevent nodes from starvation.When compared to traditional algorithms, AHDME does not require the fixed size of request queues and the global system information, which adapts itself to the frequent arrival/departures and the limited computing capability of nodes in Ad hoc networks.Performance analysis and simulation results show that the AHDME algorithm has low message complexity, small space complexity, and short response delay.

  8. Focus Group Study Exploring Factors Related to Frequent Sickness Absence.

    Directory of Open Access Journals (Sweden)

    Annette Notenbomer

    Full Text Available Research investigating frequent sickness absence (3 or more episodes per year is scarce and qualitative research from the perspective of frequent absentees themselves is lacking. The aim of the current study is to explore awareness, determinants of and solutions to frequent sickness absence from the perspective of frequent absentees themselves.We performed a qualitative study of 3 focus group discussions involving a total of 15 frequent absentees. Focus group discussions were audiotaped and transcribed verbatim. Results were analyzed with the Graneheim method using the Job Demands Resources (JD-R model as theoretical framework.Many participants were not aware of their frequent sickness absence and the risk of future long-term sickness absence. As determinants, participants mentioned job demands, job resources, home demands, poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Managing these factors and improving communication (skills were regarded as solutions to reduce frequent sickness absence.The JD-R model provided a framework for determinants of and solutions to frequent sickness absence. Additional determinants were poor health, chronic illness, unhealthy lifestyles, and diminished feeling of responsibility to attend work in cases of low job resources. Frequent sickness absence should be regarded as a signal that something is wrong. Managers, supervisors, and occupational health care providers should advise and support frequent absentees to accommodate job demands, increase both job and personal resources, and improve health rather than express disapproval of frequent sickness absence and apply pressure regarding work attendance.

    To test the feasibility and assess the uptake and acceptability of implementing a consumer questions programme, AskShareKnow, to encourage consumers to use the questions '1. What are my options; 2. What are the possible benefits and harms of those options; 3. How likely are each of those benefits and harms to happen to me?' These three questions have previously shown important effects in improving the quality of information provided during consultations and in facilitating patient involvement. This single-arm intervention study invited participants attending a reproductive and sexual health-care clinic to view a 4-min video-clip in the waiting room. Participants completed three questionnaires: (T1) prior to viewing the intervention; (T2) immediately after their consultation; and (T3) two weeks later. A total of 121 (78%) participants viewed the video-clip before their consultation. Eighty-four (69%) participants asked one or more questions, and 35 (29%) participants asked all three questions. For those making a decision, 55 (87%) participants asked one or more questions, while 27 (43%) participants asked all three questions. Eighty-seven (72%) participants recommended the questions. After two weeks, 47 (49%) of the participants recalled the questions. Enabling patients to view a short video-clip before an appointment to improve information and involvement in health-care consultations is feasible and led to a high uptake of question asking in consultations. This AskShareKnow programme is a simple and feasible method of training patients to use a brief consumer-targeted intervention that has previously shown important effects in improving the quality of information provided during consultations and in facilitating patient involvement and use of evidence-based questions. ©2015 The Authors.

    Frequent Pattern mining plays an essential role in data mining.Most of the previous studies adopt an Apriori-like candidate set generation-and-test approach. However, candidate set generation is still costly, especially when there exist prolific patterns and/or long patterns. In this study, we introduce a novel frequent pattern growth (FP-growth)method, which is efficient and scalable for mining both long and short frequent patterns without candidate generation. And build a new projection frequent pattern tree (PFP-tree) algorithm on this study, which not only heirs all the advantages in the FP-growth method, but also avoids it's bottleneck in database size dependence when constructing the frequent pattern tree (FP-tree). Efficiency of mining is achieved by introducing the projection technique, which avoid serial scan each frequent item in the database, the cost is mainly related to the depth of the tree, namely the number of frequent items of the longest transaction in the database, not the sum of all the frequent items in the database,which hugely shortens the time of tree-construction. Our performance study shows that the PFP-tree method is efficient and scalable for mining large databases or data warehouses, and is even about an order of magnitude faster than the FP-growth method.

  14. An Efficient Algorithm for Mining Maximal Frequent Item Sets

    Directory of Open Access Journals (Sweden)

    A. M.J.M.Z. Rahman


    Full Text Available Problem Statement: In today's life, the mining of frequent patterns is a basic problem in data mining applications. The algorithms which are used to generate these frequent patterns must perform efficiently. The objective was to propose an effective algorithm which generates frequent patterns in less time. Approach: We proposed an algorithm which was based on hashing technique and combines a vertical tidset representation of the database with effective pruning mechanisms. It removes all the non-maximal frequent item-sets to get exact set of MFI directly. It worked efficiently when the number of item-sets and tid-sets is more. Results: The performance of our algorithm had been compared with recently developed MAFIA algorithm and the results show how our algorithm gives better performance. Conclusions: Hence, the proposed algorithm performs effectively and generates frequent patterns faster.

  15. Pushing Multiple Convertible Constrains into Frequent Itemsets Mining

    Institute of Scientific and Technical Information of China (English)

    SONG Baoli; QIN Zheng


    Constraint pushing techniques have been developed for mining frequent patterns and association rules. However, multiple constraints cannot be handled with existing techniques in frequent pattern mining. In this paper, a new algorithm MCFMC (mining complete set of frequent itemsets with multiple constraints) is introduced. The algorithm takes advantage of the fact that a convertible constraint can be pushed into mining algorithm to reduce mining research spaces. By using a sample database, the algorithm develops techniques which select an optimal method based on a sample database to convert multiple constraints into multiple convertible constraints, disjoined by conjunction and/or, and then partition these constraints into two parts. One part is pushed deep inside the mining process to reduce the research spaces for frequent itemsets, the other part that cannot be pushed in algorithm is used to filter the complete set of frequent itemsets and get the final result. Results from our detailed experiment show the feasibility and effectiveness of the algorithm.

    Full Text Available Homelessness, HIV, and substance use are interwoven problems. Furthermore, homeless individuals are frequent users of emergency services. The main purpose of this study was to identify risk factors for frequent emergency room (ER visits and to examine the effects of housing status and HIV serostatus on ER utilization. The second purpose was to identify risk factors for frequent ER visits in patients with a history of illicit drug use.A retrospective analysis was performed on 412 patients enrolled in a Boston-based health care for the homeless program (HCH. This study population was selected as a 2:1 HIV seronegative versus HIV seropositive match based on age, sex, and housing status. A subgroup analysis was performed on 287 patients with history of illicit drug use. Chart data were analyzed to compare demographics, health characteristics, and health service utilization. Results were stratified by housing status. Logistic models using generalized estimating equations were used to predict frequent ER visits.In homeless patients, hepatitis C was the only predictor of frequent ER visits (OR 4.49, p<0.01. HIV seropositivity was not predictive of frequent ER visits. In patients with history of illicit drug use, mental health (OR 2.53, 95% CI 1.07-5.95 and hepatitis C (OR 2.85, 95% CI 1.37-5.93 were predictors of frequent ER use. HIV seropositivity did not predict ER use (OR 0.45, 95% CI 0.21 - 0.97.In a HCH population, hepatitis C predicted frequent ER visits in homeless patients. HIV seropositivity did not predict frequent ER visits, likely because HIV seropositive HCH patients are engaged in care. In patients with history of illicit drug use, hepatitis C and mental health disorders predicted frequent ER visits. Supportive housing for patients with mental health disorders and hepatitis C may help prevent unnecessary ER visits in this population.

  17. Ask: a health advocacy program for adolescents with an intellectual disability: a cluster randomised controlled trial

    Directory of Open Access Journals (Sweden)

    Lennox Nicholas


    Full Text Available Abstract Background Adolescents with intellectual disability often have poor health and healthcare. This is partly as a consequence of poor communication and recall difficulties, and the possible loss of specialised paediatric services. Methods/Design A cluster randomised trial was conducted with adolescents with intellectual disability to investigate a health intervention package to enhance interactions among adolescents with intellectual disability, their parents/carers, and general practitioners (GPs. The trial took place in Queensland, Australia, between February 2007 and September 2010. The intervention package was designed to improve communication with health professionals and families’ organisation of health information, and to increase clinical activities beneficial to improved health outcomes. It consisted of the Comprehensive Health Assessment Program (CHAP, a one-off health check, and the Ask Health Diary, designed for on-going use. Participants were drawn from Special Education Schools and Special Education Units. The education component of the intervention was delivered as part of the school curriculum. Educators were surveyed at baseline and followed-up four months later. Carers were surveyed at baseline and after 26 months. Evidence of health promotion, disease prevention and case-finding activities were extracted from GPs clinical records. Qualitative interviews of educators occurred after completion of the educational component of the intervention and with adolescents and carers after the CHAP. Discussion Adolescents with intellectual disability have difficulty obtaining many health services and often find it difficult to become empowered to improve and protect their health. The health intervention package proposed may aid them by augmenting communication, improving documentation of health encounters, and improving access to, and quality of, GP care. Recruitment strategies to consider for future studies in this population

    Foresta, Carlo; Pizzol, Damiano


    To understand and analyze what young Italian males attending high school would like to ask andrologists but do not know how to or do not have the courage to do so. As part of our "Androlife" campaign, we invited 1565 students attending the last year of high school to participate in our research. Firstly, they attended a lesson on general and andrological health and then, on a voluntary basis, they responded to a survey and were subjected to a preventive andrological visit. The data analysis showed that the main topics in which young people are interested are: sexual activity and sexuality, sexually transmitted diseases, andrological health and fertility, and lifestyle. This study highlights that young people are very interested in sexual health issues and that they have specific needs and interests with regard to sexual health information. Public education campaigns such as Androlife should be supported and further improved on the basis of the advice received by young participants. Sexual and reproductive health education targeting adolescents and young adults represent the basis both for wellness and for fertility preservation, and thus benefits of increased support to educational campaigns would be apparent not only in terms of individual health but also in terms of cost reduction in public spending.

  19. How you ask is what you get: Framing effects in willingness-to-pay for a QALY. (United States)

    Ahlert, Marlies; Breyer, Friedrich; Schwettmann, Lars


    In decisions on financing new and innovative health care technologies a central question is how to determine the value citizens place on the gains in health and life expectancy that result from respective medical treatments. We report results of surveys of four representative samples of the German population. In 2010 and 2012, in total about 5000 respondents were asked for their willingness-to-pay (WTP) for either an extension of their life or an improvement in their health corresponding to a gain of one quality-adjusted life year (QALY). Specific changes of the study design allow for ceteris paribus comparisons of different survey versions. While the initial version exactly copied a questionnaire used in the EuroVaQ (European Value of a QALY) project, which was conducted in nine European countries and Palestine, but not in Germany, in other versions the wording and the survey technique were modified. The findings show that the technique of posing the questions plays an important role when respondents are asked to imagine being in hypothetical situations. This clearly refers to the wording of the questions and the survey setting (personal or online interview). But even simple design elements such as putting a yes/no filter in front greatly affect the answers in terms of both the frequency of zero WTP and the distribution of positive amounts. From the different results, we conclude that it is inevitable to conduct studies comprising a broad variety of versions when trying to elicit WTP for a specific type of QALY in order to achieve an array of values combined by insights into the principles of their sensitivity.

  20. Efficient Mining of Frequent Closed XML Query Pattern

    Previous research works have presented convincing arguments that a frequent pattern mining algorithm should not mine all frequent but only the closed ones because the latter leads to not only more compact yet complete result set but also better efficiency. Upon discovery of frequent closed XML query patterns, indexing and caching can be effectively adopted for query performance enhancement. Most of the previous algorithms for finding frequent patterns basically introduced a straightforward generate-and-test strategy. In this paper, we present SOLARIA*, an efficient algorithm for mining frequent closed XML query patterns without candidate maintenance and costly tree-containment checking. Efficient algorithm of sequence mining is involved in discovering frequent tree-structured patterns, which aims at replacing expensive containment testing with cheap parent-child checking in sequences. SOLARIA* deeply prunes unrelated search space for frequent pattern enumeration by parent-child relationship constraint. By a thorough experimental study on various real-life data, we demonstrate the efficiency and scalability of SOLARIA* over the previous known alternative. SOLARIA* is also linearly scalable in terms of XML queries' size.

  1. Extremely frequent behavior in consumer research: theory and empirical evidence for chronic casino gambling. (United States)

    Perfetto, Ralph; Woodside, Arch G


    The present study informs understanding of customer segmentation strategies by extending Twedt's heavy-half propositions to include a segment of users that represent less than 2% of all households-consumers demonstrating extremely frequent behavior (EFB). Extremely frequent behavior (EFB) theory provides testable propositions relating to the observation that few (2%) consumers in many product and service categories constitute more than 25% of the frequency of product or service use. Using casino gambling as an example for testing EFB theory, an analysis of national survey data shows that extremely frequent casino gamblers do exist and that less than 2% of all casino gamblers are responsible for nearly 25% of all casino gambling usage. Approximately 14% of extremely frequent casino users have very low-household income, suggesting somewhat paradoxical consumption patterns (where do very low-income users find the money to gamble so frequently?). Understanding the differences light, heavy, and extreme users and non-users can help marketers and policymakers identify and exploit "blue ocean" opportunities (Kim and Mauborgne, Blue ocean strategy, Harvard Business School Press, Boston, 2005), for example, creating effective strategies to convert extreme users into non-users or non-users into new users.

    Full Text Available Now a days, Association rule plays an important role. The purchasing of one product when another product is purchased represents an association rule. The Apriori algorithm is the basic algorithm for mining association rules. This paper presents an efficient Partition Algorithm for Mining Frequent Itemsets(PAFI using clustering. This algorithm finds the frequent itemsets by partitioning the database transactions into clusters. Clusters are formed based on the imilarity measures between the transactions. Then it finds the frequent itemsets with the transactions in the clusters directly using improved Apriori algorithm which further reduces the number of scans in the database and hence improve the efficiency.

    QU Lin; CHEN Yao-wu


    A frequent trajectory patterns mining algorithm is proposed to learn the object activities and classify the trajectories in intelligent visual surveillance system. The distribution patterns of the trajectories were generated by an Apriori based frequent patterns mining algorithm and the trajectories were classified by the frequent trajectory patterns generated. In addition, a fuzzy c-mcans (FCM) based learning algorithm and a mean shift based clustering procedure were used to construct the representation of trajectories. The algorithm can be further used to describe activities and identify anomalies. The experiments on two real scenes show that the algorithm is effective.

    Full Text Available In this paper a new mining algorithm is defined based on frequent item set. Apriori Algorithm scans the database every time when it finds the frequent item set so it is very time consuming and at each step it generates candidate item set. So for large databases it takes lots of space to store candidate item set. The defined algorithm scans the database at the start only once and then makes the undirected item set graph. From this graph by considering minimum support it finds the frequent item set and by considering the minimum confidence it generates the association rule. If database and minimum support is changed, the new algorithm finds the new frequent items by scanning undirected item set graph. That is why it’s executing efficiency is improved distinctly compared to traditional algorithm.

  9. [Epidemiological evaluation of soft drinks consumption--students surveys]. (United States)

    Chłapowska, Joanna; Pawlaczyk-Kamieńska, Tamara


    Non carious lesions, including erosion changes, are becoming increasingly apparent. There are multiple factors involved in the etiology of dental erosion i.a. acids in commercially available drinks. The aim of this study was to determine the frequency of soft drink consumption that promote dental erosion among young adults. The 266 subjects were asked to fill in a questionnaire. The questionnaire inquired questions about consumption of drinks favouring tooth erosion. The students declared frequent drinking of isotonic drinks, energetic drinks, fizzy drinks and coca-cola type drinks. On the basis of a survey of Poznań University of Medical Sciences students it can be determined, that they have relatively high risk of dental erosion. To minimize the risk of dental erosion occurrence in young population there is a need to disseminate knowledge about the etiology.

    Surgery theory, the basis for the classification theory of manifolds, is now about forty years old. The sixtieth birthday (on December 14, 1996) of C.T.C. Wall, a leading member of the subject''s founding generation, led the editors of this volume to reflect on the extraordinary accomplishments of surgery theory as well as its current enormously varied interactions with algebra, analysis, and geometry. Workers in many of these areas have often lamented the lack of a single source surveying surgery theory and its applications. Because no one person could write such a survey, the editors ask

  13. Incremental Mining for Regular Frequent Patterns in Vertical Format

    Directory of Open Access Journals (Sweden)

    Vijay Kumar G


    Full Text Available In the real world database updates continuously in several online applications like super market, network monitoring, web administration, stock market etc. Frequent pattern mining is afundamental and essential area in data mining research. Not only occurrence frequency of a pattern but also occurrence behaviour of a pattern may be treated as important criteria to measure the interestingness of a pattern. A frequent pattern is said to be regular frequent if the occurrence behaviour is less than or equal to the user given regularity threshold. In incremental transactional databases the occurrence frequency and the occurrence behaviour of a pattern changes whenever a small set of new transactions are added to the database. It is undesirable to mine regular frequent patterns from the scratch. Thus proposes a new algorithm called RFPID (Regular Frequent Pattern Mining in Incremental Databases to mine regular frequent patterns in incremental transactional databases using vertical data format which requires only one database scan. The experimental results show our algorithm is efficient in both memory utilization and execution.

  14. Maintaining Discovered Frequent Itemsets: Cases for Changeable Database and Support

    Institute of Scientific and Technical Information of China (English)

    DU XiaoPing(杜孝平); TANG ShiWei(唐世渭); Akifumi Makinouchi(牧之内顕文)


    Mining frequent itemsets from large databases has played an essential role inmany data mining tasks. It is also important to maintain the discovered frequent itemsets forthese data mining tasks when the database is updated. All algorithms proposed so far for the maintenance of discovered frequent itemsets are only performed with a fixed minimum support,which is the same as that used to obtain the discovered frequent itemsets. That is, users cannot change the minimum support even if the new results are unsatisfactory to the users. In thispaper two new complementary algorithms, FMP (First Maintaining Process) and RMP (Repeated Maintaining Process), are proposed to maintain discovered frequent itemsets in the case that new transaction data are added to a transaction database. Both algorithms allow users to change theminimum support for the maintenance processes. FMP is used for the first maintaining process, andwhen the result derived from the FMP is unsatisfactory, RMP will be performed repeatedly untilsatisfactory results are obtained. The proposed algorithms re-use the previous results to cut downthe cost of maintenance. Extensive experiments have been conducted to assess the performance of the algorithms. The experimental results show that the proposed algorithms are very resultful compared with the previous mining and maintenance algorithms for maintenance of discovered frequent itemsets.

  15. Mining Maximal Frequent Patterns in a Unidirectional FP-tree

    SONG Jing-jing; LIU Rui-xin; WANG Yan; JIANG Bao-qing


    Becausemining complete set of frequent patterns from dense database could be impractical, an interesting alternative has been proposed recently. Instead of mining the complete set of frequent patterns, the new model only finds out the maximal frequent patterns, which can generate all frequent patterns. FP-growth algorithm is one of the most efficient frequent-pattern mining methods published so far. However,because FP-tree and conditional FP-trees must be two-way traversable, a great deal memory is needed in process of mining. This paper proposes an efficient algorithm Unid_FP-Max for mining maximal frequent patterns based on unidirectional FP-tree. Because of generation method of unidirectional FP-tree and conditional unidirectional FP-trees, the algorithm reduces the space consumption to the fullest extent. With the development of two techniques:single path pruning and header table pruning which can cut down many conditional unidirectional FP-trees generated recursively in mining process, Unid_ FP-Max further lowers the expense of time and space.

    Kai Zhang


    Full Text Available The behavior of Chinese patients seeking help for erectile dysfunction (ED has not been described in detail. This was an observational study conducted using an outpatient clinic-based questionnaire survey of ED patients. From 2008 to 2009, physicians in 10 medical centers in China enrolled 2693 men (aged 25-70 years diagnosed with ED. The diagnosis was based on the International Index of Erectile Function 5 (IIEF-5 Questionnaire. The men completed a survey that asked questions about demographics, marital status, education level and household income as well as help-seeking behavior and awareness of medical therapy. The mean age of the 2693 men was 43.4 ± 5.3 years; 73% were <50-years-old and 49% had a high household income. The mean time between noticing ED and taking the first treatment was 4.3 ± 2.1 months. Of the 2577 respondents, physicians (54% and the internet (52% were most frequently consulted sources for information about ED. Young ED patients preferred using the internet and older patients preferred consulting with physicians. Western medicine (19% and traditional Chinese medicine (16% were most frequently used for treatment. Young ED patients preferred to first search the internet for information, whereas older patients first asked physicians for help. Side effects of treatment were the greatest concern, especially for older patients. Physicians and the internet are frequently consulted for ED information and therapy. On the basis of these survey results, we believe that physicians in China should enhance health education about ED, especially via the internet.

  17. Why eat at fast-food restaurants: reported reasons among frequent consumers. (United States)

    Rydell, Sarah A; Harnack, Lisa J; Oakes, J Michael; Story, Mary; Jeffery, Robert W; French, Simone A


    A convenience sample of adolescents and adults who regularly eat at fast-food restaurants were recruited to participate in an experimental trial to examine the effect of nutrition labeling on meal choices. As part of this study, participants were asked to indicate how strongly they agreed or disagreed with 11 statements to assess reasons for eating at fast-food restaurants. Logistic regression was conducted to examine whether responses differed by demographic factors. The most frequently reported reasons for eating at fast-food restaurants were: fast food is quick (92%), restaurants are easy to get to (80%), and food tastes good (69%). The least frequently reported reasons were: eating fast food is a way of socializing with family and friends (33%), restaurants have nutritious foods to offer (21%), and restaurants are fun and entertaining (12%). Some differences were found with respect to the demographic factors examined. It appears that in order to reduce fast-food consumption, food and nutrition professionals need to identify alternative quick and convenient food sources. As motivation for eating at fast-food restaurants appears to differ somewhat by age, sex, education, employment status, and household size, tailored interventions could be considered.

    Apoptosis signal-regulating kinase-1 (ASK1) is the mitogen-activated protein kinase kinase kinase (MAPKKK) and participates in the various central nervous system (CNS) signaling pathways. In cerebral ischemia, vascular permeability in the brain is an important issue because regulation failure of it results in edema formation and blood-brain barrier (BBB) disruption. To determine the role of ASK1 on vascular permeability and edema formation following cerebral ischemia, we first investigated ASK1-related gene expression using microarray analyses of ischemic brain tissue. We then measured protein levels of ASK1 and vascular endothelial growth factor (VEGF) in brain endothelial cells after hypoxia injury. We also examined protein expression of ASK1 and VEGF, edema formation, and morphological alteration through cresyl violet staining in ischemic brain tissue using ASK1-small interference RNA (ASK1-siRNA). Finally, immunohistochemistry was performed to examine VEGF and aquaporin-1 (AQP-1) expression in ischemic brain injury. Based on our findings, we propose that ASK1 is a regulating factor of vascular permeability and edema formation in cerebral ischemia.

  11. Mining Frequent Generalized Itemsets and Generalized Association Rules Without Redundancy

    Institute of Scientific and Technical Information of China (English)

    Daniel Kunkle; Donghui Zhang; Gene Cooperman


    This paper presents some new algorithms to efficiently mine max frequent generalized itemsets (g-itemsets) and essential generalized association rules (g-rules). These are compact and general representations for all frequent patterns and all strong association rules in the generalized environment. Our results fill an important gap among algorithms for frequent patterns and association rules by combining two concepts. First, generalized itemsets employ a taxonomy of items, rather than a fiat list of items. This produces more natural frequent itemsets and associations such as (meat, milk) instead of (beef, milk), (chicken, milk), etc. Second, compact representations of frequent itemsets and strong rules, whose result size is exponentially smaller, can solve a standard dilemma in mining patterns: with small threshold values for support and confidence, the user is overwhelmed by the extraordinary number of identified patterns and associations; but with large threshold values, some interesting patterns and associations fail to be identified. Our algorithms can also expand those max frequent g-itemsets and essential g-rules into the much larger set of ordinary frequent g-itemsets and strong g-rules. While that expansion is not recommended in most practical cases, we do so in order to present a comparison with existing algorithms that only handle ordinary frequent g-itemsets. In this case, the new algorithm is shown to be thousands, and in some cases millions, of the time faster than previous algorithms. Further, the new algorithm succeeds in analyzing deeper taxonomies, with the depths of seven or more. Experimental results for previous algorithms limited themselves to taxonomies with depth at most three or four. In each of the two problems, a straightforward lattice-based approach is briefly discussed and then a classificationbased algorithm is developed. In particular, the two classification-based algorithms are MFGI_class for mining max frequent g-itemsets and EGR

  15. Efficient Incremental Maintenance of Frequent Patterns with FP-Tree

    Institute of Scientific and Technical Information of China (English)

    Xiu-Li Ma; Yun-Hai Tong; Shi-Wei Tang; Dong-Qing Yang


    Mining frequent patterns has been studied popularly in data mining area. However, little work has been done on mining patterns when the database has an influx of fresh data constantly. In these dynamic scenarios, efficient maintenance of the discovered patterns is crucial. Most existing methods need to scan the entire database repeatedly, which is an obvious disadvantage. In this paper, an efficient incremental mining algorithm, Incremental-Mining (IM), is proposed for maintenance of the frequent patterns when new incremental data come. Based on the frequent pattern tree (FP-tree) structure, IM gives a way to make the most of the things from the previous mining process, and requires scanning the original data once at most. Furthermore, IM can identify directly the differential set of frequent patterns, which may be more informative to users. Moreover, IM can deal with changing thresholds as well as changing data, thus provide a full maintenance scheme. IM has been implemented and the performance study shows it outperforms three other incremental algorithms: FUP, DB-tree and re-running frequent pattern growth (FP-growth).

  16. Extracting Frequent Connected Subgraphs from Large Graph Sets

    Wei Wang; Qing-Qing Yuan; Hao-Feng Zhou; Ming-Sheng Hong; Bai-Le Shi


    Mining frequent patterns from datasets is one of the key success of data mining research. Currently, most of the studies focus on the data sets in which the elements are independent, such as the items in the marketing basket.. However, the objects in the real world often have close relationship with each other. How to extract frequent patterns from these relations is the objective of this paper. The authors use graphs to model the relations, and select a simple type for analysis. Combining the graph theory and algorithms to generate frequent patterns, a new algorithm called Topology, which can mine these graphs efficiently, has been proposed. The performance of the algorithm is evaluated by doing experiments with synthetic datasets and real data. The experimental results show that Topology can do the job well. At the end of this paper, the potential improvement is mentioned.

  17. Significant Interval and Frequent Pattern Discovery in Web Log Data

    CERN Document Server

    Saxena, Kanak


    There is a considerable body of work on sequence mining of Web Log Data. We are using One Pass frequent Episode discovery (or FED) algorithm, takes a different approach than the traditional apriori class of pattern detection algorithms. In this approach significant intervals for each Website are computed first (independently) and these interval used for detecting frequent patterns/Episode and then the Analysis is performed on Significant Intervals and frequent patterns That can be used to forecast the user's behavior using previous trends and this can be also used for advertising purpose. This type of applications predicts the Website interest. In this approach, time-series data are folded over a periodicity (day, week, etc.) Which are used to form the Interval? Significant intervals are discovered from these time points that satisfy the criteria of minimum confidence and maximum interval length specified by the user.

  18. Discovering Frequent Subtrees from XML Data Using Neural Networks

    Institute of Scientific and Technical Information of China (English)


    By rapid progress of network and storage technologies, a huge amount of electronic data such as Web pages and XML has been available on Internet. In this paper, we study a data-mining problem of discovering frequent ordered sub-trees in a large collection of XML data, where both of the patterns and the data are modeled by labeled ordered trees. We present an efficient algorithm of Ordered Subtree Miner(OSTMiner) based on two- layer neural networks with Hebb rule, that computes all ordered sub-trees appearing in a collection of XML trees with frequent above a user-specified threshold using a special structure EM-tree. In this algorithm, EM-tree is used as an extended merging tree to supply scheme information for efficient pruning and mining frequent sub-trees. Experiments results showed that OSTMiner has good response time and scales well.

  20. A Frame Work for Frequent Pattern Mining Using Dynamic Function

    Directory of Open Access Journals (Sweden)

    Sunil Joshi


    Full Text Available Discovering frequent objects (item sets, sequential patterns is one of the most vital fields in data mining. It is well understood that it require running time and memory for defining candidates and this is the motivation for developing large number of algorithm. Frequent patterns mining is the paying attention research issue in association rules analysis. Apriori algorithm is a standard algorithm of association rules mining. Plenty of algorithms for mining association rules and their mutations are projected on the foundation of Apriori Algorithm. Most of the earlier studies adopted Apriori-like algorithms which are based on generate-and-test candidates theme and improving algorithm approach and formation but no one give attention to the structure of database. Several modifications on apriori algorithms are focused on algorithm Strategy but no one-algorithm emphasis on least transaction and more attribute representation of database. We presented a new research trend on frequent pattern mining in which generate Transaction pair to lighten current methods from the traditional blockage, providing scalability to massive data sets and improving response time. In order to mine patterns in database with more columns than rows, we proposed a complete framework for the frequent pattern mining. A simple approach is if we generate pair of transaction instead of item id where attributes are much larger then transaction so result is very fast. Newly, different works anticipated a new way to mine patterns in transposed databases where there is a database with thousands of attributes but merely tens of stuff. We suggest a novel dynamic algorithm for frequent pattern mining in which generate transaction pair and for generating frequent pattern we find out by longest common subsequence using dynamic function. Our solutions give result more rapidly. A quantitative investigation of these tradeoffs is conducted through a wide investigational study on artificial and

    We propose an efficient hybrid algorithm WDHP in this paper for mining frequent access patterns.WDHP adopts the techniques of DHP to optimize its performance, which is using hash table to filter candidate set and trimming database.Whenever the database is trimmed to a size less than a specified threshold, the algorithm puts the database into main memory by constructing a tree, and finds frequent patterns on the tree.The experiment shows that WDHP outperform algorithm DHP and main memory based algorithm WAP in execution efficiency.

  4. Mining Frequent Itemsets from Online Data Streams: Comparative Study

    Directory of Open Access Journals (Sweden)

    HebaTallah Mohamed Nabil


    Full Text Available Online mining of data streams poses many new challenges more than mining static databases. In addition to the one-scan nature, the unbounded memory requirement, the high data arrival rate of data streams and the combinatorial explosion of itemsets exacerbate the mining task. The high complexity of the frequent itemsets mining problem hinders the application of the stream mining techniques. In this review, we present a comparative study among almost all, as we are acquainted, the algorithms for mining frequent itemsets from online data streams. All those techniques immolate with the accuracy of the results due to the relatively limited storage, leading, at all times, to approximated results.

  5. Frequent rhabdomyolysis in anti-NMDA receptor encephalitis. (United States)

    The aim of this study was to analyze the clinical presentation and provocation factors of rhabdomyolysis in anti-NMDAR encephalitis. Among the 16 patients with anti-NMDAR encephalitis in our institutional cohort, nine patients had elevated CK enzyme levels and clinical evidence of rhabdomyolysis. Rhabdomyolysis was more frequent after immunotherapy. The use of dopamine receptor blocker (DRB) increased the risk of rhabdomyolysis. None of the patients without rhabdomyolysis received DRBs. Rhabdomyolysis is a frequent complication in anti-NMDAR encephalitis and more common after immunotherapy and the use of DRBs increases the risk. Therefore, DRBs should be administered carefully in patients with anti-NMDAR encephalitis.

  6. AskHERMES: An online question answering system for complex clinical questions. (United States)

    Cao, YongGang; Liu, Feifan; Simpson, Pippa; Antieau, Lamont; Bennett, Andrew; Cimino, James J; Ely, John; Yu, Hong


    Clinical questions are often long and complex and take many forms. We have built a clinical question answering system named AskHERMES to perform robust semantic analysis on complex clinical questions and output question-focused extractive summaries as answers. This paper describes the system architecture and a preliminary evaluation of AskHERMES, which implements innovative approaches in question analysis, summarization, and answer presentation. Five types of resources were indexed in this system: MEDLINE abstracts, PubMed Central full-text articles, eMedicine documents, clinical guidelines and Wikipedia articles. We compared the AskHERMES system with Google (Google and Google Scholar) and UpToDate and asked physicians to score the three systems by ease of use, quality of answer, time spent, and overall performance. AskHERMES allows physicians to enter a question in a natural way with minimal query formulation and allows physicians to efficiently navigate among all the answer sentences to quickly meet their information needs. In contrast, physicians need to formulate queries to search for information in Google and UpToDate. The development of the AskHERMES system is still at an early stage, and the knowledge resource is limited compared with Google or UpToDate. Nevertheless, the evaluation results show that AskHERMES' performance is comparable to the other systems. In particular, when answering complex clinical questions, it demonstrates the potential to outperform both Google and UpToDate systems. AskHERMES, available at, has the potential to help physicians practice evidence-based medicine and improve the quality of patient care. Copyright © 2011 Elsevier Inc. All rights reserved.

  7. Coital frequency and infertility: which male factors predict less frequent coitus among infertile couples? (United States)

    Perlis, Nathan; Lo, Kirk C; Grober, Ethan D; Spencer, Leia; Jarvi, Keith


    To determine the coital frequency among infertile couples and which factors are associated with less frequent coitus. Cross-sectional study. Tertiary-level male infertility clinic. A total of 1,298 infertile men. Administration of computer-based survey, semen analysis, and serum hormone evaluation. Monthly coital frequency. A total of 1,298 patients presented to clinic for infertility consultation and completed the computer-based survey. The median male age was 35 years (interquartile range [IQR] 32-39 years) and the median duration of infertility was 2 years (IQR 1-4 years) before consultation. Median monthly coital frequency was seven (IQR 5-10; range 0-40); 24% of couples were having intercourse ≤ 4 times per month. Overall, 0.6%, 2.7%, 4.8%, 5.8%, and 10.8% of the men reported having intercourse 0, 1, 2, 3, and 4 times per month, respectively. When simultaneously taking into account the influence of age, libido, erectile function, and semen volume on coital frequency, older patients had 1.05 times higher odds (per year of age) of less frequent coitus (odds ratio 1.05, 95% confidence interval 1.03-1.08). In addition, patients with better erectile function had 1.12 times higher odds (per point on Sexual Health Inventory for Men scale) of more frequent coitus (odds ratio 1.12, 95% confidence interval 1.09-1.18). Similar to the general population, most infertile couples report having coitus more than four times per month. Older male age and erectile dysfunction are independent risk factors for less frequent coitus among infertile men, which could have an impact on fertility. Coital frequency should be considered in infertility assessments. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

  16. Frequent visitors at the psychiatric emergency room - A literature review. (United States)

    Schmidt, Manuela


    Frequent visitors at the psychiatric emergency room (PER) constitute a small subgroup of patients, yet they are responsible for a disproportionate number of visits and thus claim considerable resources. Their needs are often left unmet and their repetitive visits reflect their dissatisfaction as well as that of PERs' staff. Motivated by these dilemmas, this study systematically reviews the literature about frequent visitors at PER and seeks to answer two questions: What characterizes frequent visitors at PER in the literature? and What characterizes PER in the literature? Based on 29 studies, this paper offers answers to the two questions based on a strength weakness opportunities and threats (SWOT) analysis. The results of the review and subsequent analysis of the literature revealed the multiplicity and complexity of frequent visitors' characteristics and how they appear to converge. Commonalities were more difficult to identify in PER characteristics. In some cases, this happened because the characteristics were poorly described or were context specific. As a result, it was not easy to compare the studies on PER. Based on SWOT and the findings of the analysis, the paper proposes new venues of research and suggests how the field of mental health might develop by taking into account its opportunities and threats.

  17. GRAMI: Generalized Frequent Subgraph Mining in Large Graphs

    KAUST Repository

    El Saeedy, Mohammed El Sayed


    Mining frequent subgraphs is an important operation on graphs. Most existing work assumes a database of many small graphs, but modern applications, such as social networks, citation graphs or protein-protein interaction in bioinformatics, are modeled as a single large graph. Interesting interactions in such applications may be transitive (e.g., friend of a friend). Existing methods, however, search for frequent isomorphic (i.e., exact match) subgraphs and cannot discover many useful patterns. In this paper we propose GRAMI, a framework that generalizes frequent subgraph mining in a large single graph. GRAMI discovers frequent patterns. A pattern is a graph where edges are generalized to distance-constrained paths. Depending on the definition of the distance function, many instantiations of the framework are possible. Both directed and undirected graphs, as well as multiple labels per vertex, are supported. We developed an efficient implementation of the framework that models the frequency resolution phase as a constraint satisfaction problem, in order to avoid the costly enumeration of all instances of each pattern in the graph. We also implemented CGRAMI, a version that supports structural and semantic constraints; and AGRAMI, an approximate version that supports very large graphs. Our experiments on real data demonstrate that our framework is up to 3 orders of magnitude faster and discovers more interesting patterns than existing approaches.

  20. Results of a dosimetry study in the European Community on frequent X ray examinations in infants

    Energy Technology Data Exchange (ETDEWEB)

    Schneider, K.; Fendel, H.; Bakowski, C. (Muenchen Univ. (Germany). Kinderklinik) (and others)


    This Europe-wide dosimetry study, covering 89 departments in 11 EC countries, measured entrance surface dose (ESD) using TLDs, and surveyed X ray equipment and radiographic techniques used for frequent paediatric X ray examinations of the chest, abdomen, pelvis, skull and spine. The survey was limited to infants (10 months, 4 months and prematures of [approx] 1 kg). Data analysis showed widely differing radiographic techniques. This was one of the reasons for the large variations in ESD of an order of magnitude of 1:50. A substantial number of departments used either very old X ray generators and/or techniques poorly suited for paediatric radiology. Significant dose reduction was seen when recommended guidelines for good radiographic technique were followed. This study emphasises the necessity for the adherence to easily followed guidelines for the improvement of training and equipment in paediatric radiology. (author).

  3. How to Ask for a Favor: A Case Study on the Success of Altruistic Requests

    CERN Document Server

    Althoff, Tim; Jurafsky, Dan


    Requests are at the core of many social media systems such as question & answer sites and online philanthropy communities. While the success of such requests is critical to the success of the community, the factors that lead community members to satisfy a request are largely unknown. Success of a request depends on factors like who is asking, how they are asking, when are they asking, and most critically what is being requested, ranging from small favors to substantial monetary donations. We present a case study of altruistic requests in an online community where all requests ask for the very same contribution and do not offer anything tangible in return, allowing us to disentangle what is requested from textual and social factors. Drawing from social psychology literature, we extract high-level social features from text that operationalize social relations between recipient and donor and demonstrate that these extracted relations are predictive of success. More specifically, we find that clearly communic...

    Jasmonates are a new class of plant hormones that play important roles in plant development and plant defense. The COI1 gene was previously shown to be required for jasmonate- regulated plant fertility and defense. We demonstrated for the first time that COI1 interacts with the Arabidopsis SKP1-LIKE1 (ASK1) to form a complex that is required for jasmonate action in planta. Functional analysis by antisense strategy showed that ASK1 is involved in male fertility.

  8. Information-seeking behaviors of medical students: a classification of questions asked of librarians and physicians. (United States)

    Wildemuth, B M; de Bliek, R; Friedman, C P; Miya, T S


    To solve a problem, a person often asks questions of someone with more expertise. This paper reports on a study of the types of questions asked and how the experts are chosen. In the study, sixty-three first-year medical students responded to clinical scenarios, each describing a patient affected by a toxin and asking questions concerning the identity of the toxin and its characteristics. After answering those questions, the students were asked to imagine that they had access to a medical reference librarian and an internist specializing in toxicology. The students then generated two questions for each expert about each clinical scenario. Each question was categorized according to the type of information requested, and the frequency of each type of question was calculated. The study found that students most often asked for the identification of the toxin(s), references about the scenario, or the effects of the toxin; an explanation of the patient's symptoms; or a description of the appropriate treatment. Students were more likely to address questions on the identity of the toxin and references to the hypothetical librarian; they were more likely to ask the internist for explanations of the symptoms and descriptions of the treatment. The implications of these results for the design of information and educational systems are discussed.

  10. Evidence for frequent incest in a cooperatively breeding mammal. (United States)

    Nichols, H J; Cant, M A; Hoffman, J I; Sanderson, J L


    As breeding between relatives often results in inbreeding depression, inbreeding avoidance is widespread in the animal kingdom. However, inbreeding avoidance may entail fitness costs. For example, dispersal away from relatives may reduce survival. How these conflicting selection pressures are resolved is challenging to investigate, but theoretical models predict that inbreeding should occur frequently in some systems. Despite this, few studies have found evidence of regular incest in mammals, even in social species where relatives are spatio-temporally clustered and opportunities for inbreeding frequently arise. We used genetic parentage assignments together with relatedness data to quantify inbreeding rates in a wild population of banded mongooses, a cooperatively breeding carnivore. We show that females regularly conceive to close relatives, including fathers and brothers. We suggest that the costs of inbreeding avoidance may sometimes outweigh the benefits, even in cooperatively breeding species where strong within-group incest avoidance is considered to be the norm.

  11. Efficient Support Coupled Frequent Pattern Mining Over Progressive Databases

    CERN Document Server

    Keshavamurthy, B N; Toshniwal, Durga; 10.5121/ijdms.2010.2205


    There have been many recent studies on sequential pattern mining. The sequential pattern mining on progressive databases is relatively very new, in which we progressively discover the sequential patterns in period of interest. Period of interest is a sliding window continuously advancing as the time goes by. As the focus of sliding window changes, the new items are added to the dataset of interest and obsolete items are removed from it and become up to date. In general, the existing proposals do not fully explore the real world scenario, such as items associated with support in data stream applications such as market basket analysis. Thus mining important knowledge from supported frequent items becomes a non trivial research issue. Our proposed novel approach efficiently mines frequent sequential pattern coupled with support using progressive mining tree.

    In this paper, a new algorithm HCOUNT + is proposed to find frequent items over data stream based on the HCOUNT algorithm. The new algorithm adopts aided measures to improve the precision of HCOUNT greatly. In addition,HCOUNT + is introduced to time critical applications and a novel sliding windows-based algorithm SL-HCOUNT + is proposed to mine the most frequent items occurring recently.This algorithm uses limited memory (nB · (1 +α) · e/ε·In(-M/lnρ)(α<1) counters), requires constant processing time per packet (only (1+α) · ln(-M/lnρ(α<1)) counters are updated), makes only one pass over the streaming data,and is shown to work well in the experimental results.

    We previously reported an association between dyslipidemia and endometrial cancers. Osteoporosis is also reported to relate with some cancers. A common etiologic event has been proposed between dyslipidemia and osteoporosis. However, the pattern of interrelationships among dyslipidemia, osteoporosis and endometrial cancer is not well understood. To improve the quality of life of endometrial cancer survivors, these relationships should be determined. This study included 179 Japanese menopausal women who underwent bilateral salpingo-oophorectomy, including 114 women with incident endometrial cancer and 65 without endometrial cancer. The women were categorized according to dyslipidemia status. Bone mineral density was measured and compared between groups. Osteoporosis was statistically more frequent in women with hypertriglyceridemia who did not have endometrial cancer. In contrast, osteoporosis was statistically less frequent in women with hypertriglyceridemia who had endometrial cancer. In this cross-sectional study in a Japanese population, osteoporosis was associated with hypertriglyceridemia in post-menopausal women without endometrial cancer, but was less frequent in endometrial cancer survivors with hypertriglyceridemia.

  19. Incremental Frequent Subgraph Mining on Large Evolving Graphs

    KAUST Repository

    Abdelhamid, Ehab


    Frequent subgraph mining is a core graph operation used in many domains, such as graph data management and knowledge exploration, bioinformatics and security. Most existing techniques target static graphs. However, modern applications, such as social networks, utilize large evolving graphs. Mining these graphs using existing techniques is infeasible, due to the high computational cost. In this paper, we propose IncGM+, a fast incremental approach for continuous frequent subgraph mining problem on a single large evolving graph. We adapt the notion of “fringe” to the graph context, that is the set of subgraphs on the border between frequent and infrequent subgraphs. IncGM+ maintains fringe subgraphs and exploits them to prune the search space. To boost the efficiency, we propose an efficient index structure to maintain selected embeddings with minimal memory overhead. These embeddings are utilized to avoid redundant expensive subgraph isomorphism operations. Moreover, the proposed system supports batch updates. Using large real-world graphs, we experimentally verify that IncGM+ outperforms existing methods by up to three orders of magnitude, scales to much larger graphs and consumes less memory.

  20. Handling Dynamic Weights in Weighted Frequent Pattern Mining (United States)

    Ahmed, Chowdhury Farhan; Tanbeer, Syed Khairuzzaman; Jeong, Byeong-Soo; Lee, Young-Koo

    Even though weighted frequent pattern (WFP) mining is more effective than traditional frequent pattern mining because it can consider different semantic significances (weights) of items, existing WFP algorithms assume that each item has a fixed weight. But in real world scenarios, the weight (price or significance) of an item can vary with time. Reflecting these changes in item weight is necessary in several mining applications, such as retail market data analysis and web click stream analysis. In this paper, we introduce the concept of a dynamic weight for each item, and propose an algorithm, DWFPM (dynamic weighted frequent pattern mining), that makes use of this concept. Our algorithm can address situations where the weight (price or significance) of an item varies dynamically. It exploits a pattern growth mining technique to avoid the level-wise candidate set generation-and-test methodology. Furthermore, it requires only one database scan, so it is eligible for use in stream data mining. An extensive performance analysis shows that our algorithm is efficient and scalable for WFP mining using dynamic weights.

  5. Ask an anatomist: Identifying global trends, topics and themes of academic anatomists using twitter. (United States)

    Marsland, Madeleine J; Lazarus, Michelle D


    Social media (SoMe) is increasingly used in higher education (HE) to access knowledge and enable global communication. The SoMe platform Twitter(®) is particularly beneficial in these contexts because it is readily accessible, easily searchable (via hashtags) and global. Given these advantages, the twitter platform @AskAnatomist was created to foster a global weekly tweet chat, where students and academics from can ask and address anatomy-related questions. The aim of this study was to identify themes arising in the early stages of the @AskAnatomy Twitter community to gain insights into current needs/key areas for academic anatomists, students, and other followers. A qualitative analysis of tweets including the hashtag #AnatQ, (the associated @AskAnatomist hashtag), was undertaken to achieve this aim. Thematic analysis revealed three core themes arising in the formative stages of the @AskAnatomist Twitter site: (1) anatomical education modalities, (2) specific anatomy content, and (3) research motivations. These themes reveal controversies within the field of anatomical sciences, areas for potential education resource improvement and research, as well as the humor of anatomists. Though the original intent of the @AskAnatomist site was to engage the general public in anatomy content and knowledge, tweet analysis suggests that academic anatomists were the primary active "tweeters". Interestingly, this analysis reveals that the @AskAnatomist site progressed into a web-based community of practice (CoP), suggesting an additional benefit of SoMe communities in the field of anatomy. © 2017 American Association of Anatomists.

    Full Text Available The effect of frequent examinations on the students' learning has had inconsistent results. This study aimed to assess the effectiveness of frequent announced quizzes on the learning of a representative sample of Iranian medical students.This experimental study was conducted among 37 fifth semester medical students who had taken the course in Protozoology and Helminthology, in which the same basic information were provided about different types of protozoa and worms. Initially, in the teaching of helminthology, ten routine sessions were handled with lectures and interactive questions and answers. Then at the beginning of the protozoology topic in the beginning of all of the next 9 sessions, the students were informed that they will have a quiz at the end of each session. At the end of the semester, the total scores of quizzes were compared with the mean final scores of protozoology and helminthology using paired t and repeated measure tests.The mean final scores of the protozoology lesson were not significantly different from that of the helminthology (10.45 ± 2.75 vs.11.25 ± 2.56 on the scale of 20, respectively, P=0.13. There was no significant difference in the mean score of the five quizzes compared with the mean final term score of protozoology. The overall mean scores in the helminthology lesson (11.25±2.56, protozoology lesson (10.45±2.75, and the quizzes (9.16 ± 3.55 were significantly different (P <0.0001.Frequent announced quizzes were not effective on increasing the medical students' motivation and learning.

  7. The Moderating Effect of Frequent Singing on Voice Aging. (United States)

    Lortie, Catherine L; Rivard, Julie; Thibeault, Mélanie; Tremblay, Pascale


    The effects of aging on voice production are well documented, including changes in loudness, pitch, and voice quality. However, one important and clinically relevant question that remains concerns the possibility that the aging of voice can be prevented or at least delayed through noninvasive methods. Indeed, discovering natural means to preserve the integrity of the human voice throughout aging could have a major impact on the quality of life of elderly adults. The objective of this study was therefore to examine the potentially positive effect of singing on voice production. To this aim, a group of 72 healthy nonsmoking adults (20-93 years old) was recruited and separated into three groups based on their singing habits. Several voice parameters were assessed (fundamental frequency [f0] mean, f0 standard deviation [SD], f0 minimum and f0 maximum, mean amplitude and amplitude SD, jitter, shimmer, and harmonic-to-noise ratio) during the sustained production of vowel /a/. Other parameters were assessed during standardized reading passage (speaking f0, speaking f0 SD). As was expected, age effects were found on most acoustic parameters with significant sex differences. Importantly, moderation analyses revealed that frequent singing moderates the effect of aging on most acoustic parameters. Specifically, in frequent singers, there was no decrease in the stability of pitch and amplitude with age, suggesting that the voice of frequent singers remains more stable in aging than the voice of non-singers, and more generally, providing empirical evidence for a positive effect of singing on voice in aging.

  11. Quantifying bid-ask spreads in the Chinese stock market using limit-order book data. Intraday pattern, probability distribution, long memory, and multifractal nature (United States)

    Gu, G.-F.; Chen, W.; Zhou, W.-X.


    The statistical properties of the bid-ask spread of a frequently traded Chinese stock listed on the Shenzhen Stock Exchange are investigated using the limit-order book data. Three different definitions of spread are considered based on the time right before transactions, the time whenever the highest buying price or the lowest selling price changes, and a fixed time interval. The results are qualitatively similar no matter linear prices or logarithmic prices are used. The average spread exhibits evident intraday patterns consisting of a big L-shape in morning transactions and a small L-shape in the afternoon. The distributions of the spread with different definitions decay as power laws. The tail exponents of spreads at transaction level are well within the interval (2,3) and that of average spreads are well in line with the inverse cubic law for different time intervals. Based on the detrended fluctuation analysis, we found the evidence of long memory in the bid-ask spread time series for all three definitions, even after the removal of the intraday pattern. Using the classical box-counting approach for multifractal analysis, we show that the time series of bid-ask spread do not possess multifractal nature.

  13. Analyzing the Number of Varieties in Frequently Found Flows (United States)

    Shomura, Yusuke; Watanabe, Yoshinori; Yoshida, Kenichi

    Abnormal traffic that causes various problems on the Internet, such as P2P flows, DDoS attacks, and Internet worms, is increasing; therefore, the importance of methods that identify and control abnormal traffic is also increasing. Though the application of frequent-itemset-mining techniques is a promising way to analyze Internet traffic, the huge amount of data on the Internet prevents such techniques from being effective. To overcome this problem, we have developed a simple frequent-itemset-mining method that uses only a small amount of memory but is effective even with the large volumes of data associated with broadband Internet traffic. Using our method also involves analyzing the number of distinct elements in the itemsets found, which helps identify abnormal traffic. We used a cache-based implementation of our method to analyze actual data on the Internet and demonstrated that such an implementation can be used to provide on-line analysis of data while using only a small amount of memory.

  14. Functional Aerophagia in Children: A Frequent, Atypical Disorder

    Directory of Open Access Journals (Sweden)

    Giuliana Morabito


    Full Text Available Aerophagia is a functional gastrointestinal disorder characterized by repetitive air swallowing, abdominal distension, belching and flatulence. Pathologic aerophagia is a condition caused by the swallowing of excessive volumes of air with associated various gastrointestinal symptoms, such as burping, abdominal cramps, flatulence and a reduced appetite. It is a clinical entity that can simulate pediatric gastrointestinal motility disorders, such as gastroparesis, megacolon and intestinal pseudo-obstruction, and presents more frequently in children with mental retardation. Early recognition and diagnosis of functional aerophagia or pathologic aerophagia is required to avoid unnecessary, expensive diagnostic investigations or serious clinical complications. Functional aerophagia is frequent in the adult population, but rarely discussed in the pediatric literature. We present two pediatric clinical cases with a history of functional constipation in whom gaseous abdominal distension was the most important symptom. Mechanical intestinal obstruction, chronic intestinal pseudo-obstruction, malabsorption and congenital aganglionic megacolon were ruled out. Extensive gaseous abdominal distension was due to aerophagia, and treatment consisted of parents' reassurance and psychological counseling.

  15. Frequent chromatin rearrangements in myelodysplastic syndromes--what stands behind? (United States)

    Pagáčová, E; Falk, M; Falková, I; Lukášová, E; Michalová, K; Oltová, A; Raška, I; Kozubek, S


    Myelodysplastic syndromes (MDS) represent a clinically and genetically heterogeneous group of clonal haematopoietic diseases characterized by a short survival and high rate of transformation to acute myeloid leukaemia (AML). In spite of this variability, MDS is associated with typical recurrent non-random cytogenetic defects. Chromosomal abnormalities are detected in the malignant bone-marrow cells of approximately 40-80 % of patients with primary or secondary MDS. The most frequent chromosomal rearrangements involve chromosomes 5, 7 and 8. MDS often shows presence of unbalanced chromosomal changes, especially large deletions [del(5), del(7q), del(12p), del(18q), del(20q)] or losses of whole chromosomes (7 and Y). The most typical cytogenetic abnormality is a partial or complete deletion of 5q- that occurs in roughly 30 % of all MDS cases either as the sole abnormality or in combination with other aberrations as a part of frequently complex karyotypes. The mechanisms responsible for the formation of MDS-associated recurrent translocations and complex karyotypes are unknown. Since some of the mentioned aberrations are characteristic for several haematological malignancies, more general cellular conditions could be expected to play a role. In this article, we introduce the most common rearrangements linked to MDS and discuss the potential role of the non-random higher-order chromatin structure in their formation. A contribution of the chromothripsis - a catastrophic event discovered only recently - is considered to explain how complex karyotypes may occur (during a single event).

    Full Text Available Query sensitive summarization aims at extracting the query relevant contents from web documents. Web page segmentation focuses on reducing the run time overhead of the summarization systems by grouping the related contents of a web page into segments. At query time, query relevant segments of the web page are identified and important sentences from these segments are extracted to compose the summary. DOM tree structures of the web documents are utilized to perform the segmentation of the contents. Leaf nodes of DOM tress are merged to form segments according to the statistical and linguistic similarity measure. The proposed system has been evaluated by intrinsic approach making use of user satisfaction index. The performance of the system is compared with summarization without using preprocessed segments. Performance of this system is more promising than the other measures like cosine similarity, jaccard measure which make use of sparse term-frequent vectors, since the most frequent term sets are considered to measure the relevance. Relevant segments alone need to be processed at run time for summarization which reduces the time complexity of the summarization process.

  17. Common pharmacophore identification using frequent clique detection algorithm. (United States)

    Podolyan, Yevgeniy; Karypis, George


    The knowledge of a pharmacophore, or the 3D arrangement of features in the biologically active molecule that is responsible for its pharmacological activity, can help in the search and design of a new or better drug acting upon the same or related target. In this paper, we describe two new algorithms based on the frequent clique detection in the molecular graphs. The first algorithm mines all frequent cliques that are present in at least one of the conformers of each (or a portion of all) molecules. The second algorithm exploits the similarities among the different conformers of the same molecule and achieves an order of magnitude performance speedup compared to the first algorithm. Both algorithms are guaranteed to find all common pharmacophores in the data set, which is confirmed by the validation on the set of molecules for which pharmacophores have been determined experimentally. In addition, these algorithms are able to scale to data sets with arbitrarily large number of conformers per molecule and identify multiple ligand binding modes or multiple binding sites of the target.

  18. Fever of unknown origin: Most frequent causes in adults patients. (United States)

    Popovska-Jovicić, Biljana; Canović, Predrag; Gajović, Olgica; Raković, Ivana; Mijailović, Zeljko


    The differential diagnosis of fever of unknown origin (FUO) includes more than 200 different diseases and conditions. The aim of this study was to identify the most frequent causes of FUO among adult patients according to gender and age. The study included 74 patients examined from June 2010 to June 2013 at the Infectious Disease Clinic, Clinical Center Kragujevac in Serbia, according to the defined criteria for FUO. The patients were divided according to the diagnosis into four groups: infectious, malignant, rheumatic and "other diseases". A cause of febricity could not be estabilshed in a portion of subjects, and they comprised the group of undiagnosed cases. Infectious diseases were dominant in the study, followed by rheumatic diseases, which were most frequently found in women and the elderly. The diseases recognised as the most common causes of febricity were subacute thyroiditis, subacute endocarditis, Still's disease, rheumatic polymyalgia with or without temporal arteritis, and cytomegalovirus infection. In 44% of the patients, the final diagnosis was composed of only six clinical entities. The importance of establishing the diagnosis of rheumatic disease is especially emphasised, in line with other authors' research indicating the number of these diseases is on the rise. The diagnostic approach to FUO should always be directed to the known frequency of diseases.

  19. Graph Based New Approach for Frequent Pattern Mining

    Directory of Open Access Journals (Sweden)

    Anurag Choubey


    Full Text Available Association rule mining is a function of data mining research domain and frequent pattern mining is anessential part of it. Most of the previous studies on mining frequent patterns based on an Apriori approach, which required more number of database scans and operations for counting pattern supports in the database. Since the size of each set of transaction may be massive that it makes difficult to perform traditional data mining tasks. This research intends to propose a graph structure that captures only those itemsets that needs to define a sufficiently immense dataset into a submatrix representing important weights and does not give any chance to outliers. We have devised a strategy that covers significant facts of data by drilling down the large data into a succinct form of an Adjacency Matrix at different stages of mining process. The graph structure is so designed that it can be easily maintained and the trade off in compressing the large data values is reduced. Experimental results show the effectiveness of our graphbased approach.

  20. Substance use treatment barriers for patients with frequent hospital admissions. (United States)

    Raven, Maria C; Carrier, Emily R; Lee, Joshua; Billings, John C; Marr, Mollie; Gourevitch, Marc N


    Substance use (SU) disorders adversely impact health status and contribute to inappropriate health services use. This qualitative study sought to determine SU-related factors contributing to repeated hospitalizations and to identify opportunities for preventive interventions. Fifty Medicaid-insured inpatients identified by a validated statistical algorithm as being at high-risk for frequent hospitalizations were interviewed at an urban public hospital. Patient drug/alcohol history, experiences with medical, psychiatric and addiction treatment, and social factors contributing to readmission were evaluated. Three themes related to SU and frequent hospitalizations emerged: (a) barriers during hospitalization to planning long-term treatment and follow-up, (b) use of the hospital as a temporary solution to housing/family problems, and (c) unsuccessful SU aftercare following discharge. These data indicate that homelessness, brief lengths of stay complicating discharge planning, patient ambivalence regarding long-term treatment, and inadequate detox-to-rehab transfer resources compromise substance-using patients' likelihood of avoiding repeat hospitalization. Intervention targets included supportive housing, detox-to-rehab transportation, and postdischarge patient support.

  1. The difficulties of interprofessional teamwork in diabetes care: a questionnaire survey. (United States)

    Kishimoto, Miyako; Noda, Mitsuhiko


    Diabetes is a multifactorial disease and its nature means that interprofessional teamwork is essential for its treatment. However, in general, interprofessional teamwork has certain problems that impede its function. To clarify these problems in relation to diabetes care, a questionnaire survey was conducted. The participants who were involved in diabetes-related educational seminars, and medical personnel who were engaged in diabetes care from the National Center for Global Health and Medicine, were asked to complete the questionnaire about perceptions of, and satisfaction with, interprofessional teamwork across multiple health care providers, who were actually involved in diabetes care. From 456 people who were asked to take the questionnaire, 275 people answered. The percentages of the respondents according to profession who considered multidisciplinary teamwork sufficient were as follows: physicians, 20.5%; nurses, 12.7%; registered dietitians, 29.6%; pharmacists, 21.9%; physiotherapists, 18.2%; and clinical laboratory technicians 15.4%. Insufficient interprofessional communication and inconsistency in motivation levels among staff were frequently cited as causes of insufficient teamwork. All professions considered interprofessional meetings or conferences necessary and essential for teamwork. The survey revealed that interprofessional teamwork in diabetes care is currently insufficient. Continuous efforts to change each profession's perceptions about interprofessional teamwork and efforts to improve the quality of interprofessional meetings are necessary.

  2. Directly Printable Organic ASK Based Chipless RFID Tag for IoT Applications

    Directory of Open Access Journals (Sweden)

    A. Habib


    Full Text Available A chipless RFID tag with unique ASK encoding technique is presented in this paper. The coding efficiency is enhanced regarding tag capacity. The amplitude varia¬tions of the backscattered RFID signal is used for encoding data instead of OOK. Strips of different widths are used to have amplitude variations. The ASK technique is applied using three different substrates of Kapton®HN, PET, and paper. To incorporate ASK technique, dual polarized rhombic shaped resonators are designed. These tags operate in the frequency range of 3.1–10.6 GHz with size of 70 × 42 mm^2. The presented tags are flexible and offer easy printability. The paper-based decomposable organic tag appears as an ultra low-cost solution for wide scale tracking. This feature enables them to secure a prominent position in the emerging fields of IoT and green electronics.

  3. Are we sending the wrong message when we ask health care workers to wash their hands? (United States)

    Kurtz, Sharon L


    When asking healthcare workers to wash their hands, perhaps a better message would be to ask them not to transmit diseases. This changes the emphasis from a single act of adherence to a concept of behavior change. Proper hand hygiene, proper use of personal protective equipment, and cough etiquette are the means to an end, to stop the transfer to organisms and disease, but not the ultimate goal itself. The ultimate goal is to stop the transmission of diseases and ultimately to decrease the occurrence of healthcare associated infections.

  4. A Dynamic Analysis of Bid-Ask Spreads with Multiple Trade Sizes


    Shino Takayama; Han Ozsoylev


    This paper studies how the trade size and the historical sequence of trades affect bid-ask spreads, investors’ trading strategies, and the market maker’s learning process in a multi-period economy. First, we show that there is a nonzero cut-off size below which informed traders never buy or sell, and that larger trade sizes have positive bid-ask spreads, while smaller sizes do not. Then, we prove that the cut-off size decreases stochastically . We also derive the functional relationship betwe...

  5. The operationalisation of religion and world view in surveys of nurses' attitudes toward euthanasia and assisted suicide. (United States)

    Gielen, Joris; Van den Branden, Stef; Broeckaert, Bert


    Most quantitative studies that survey nurses' attitudes toward euthanasia and/or assisted suicide, also attempt to assess the influence of religion on these attitudes. We wanted to evaluate the operationalisation of religion and world view in these surveys. In the Pubmed database we searched for relevant articles published before August 2008 using combinations of search terms. Twenty-eight relevant articles were found. In five surveys nurses were directly asked whether religious beliefs, religious practices and/or ideological convictions influenced their attitudes, or the respondents were requested to mention the decisional basis for their answers on questions concerning end-of-life issues. In other surveys the influence of religion and world view was assessed indirectly through a comparison of the attitudes of different types of believers and/or non-believers toward euthanasia or assisted suicide. In these surveys we find subjective religious or ideological questions (questions inquiring about the perceived importance of religion or world view in life, influence of religion or world view on life in general, or how religious the respondents consider themselves) and objective questions (questions inquiring about religious practice, acceptance of religious dogmas, and religious or ideological affiliation). Religious or ideological affiliation is the most frequently used operationalisation of religion and world view. In 16 surveys only one religious or ideological question was asked. In most articles the operationalisation of religion and world view is very limited and does not reflect the diversity and complexity of religion and world view in contemporary society. Future research should pay more attention to the different dimensions of religion and world view, the religious plurality of Western society and the particularities of religion in non-Western contexts.

  6. Frequent occurrence of uniparental disomy in colorectal cancer

    DEFF Research Database (Denmark)

    Andersen, Claus Lindbjerg; Wiuf, Carsten; Kruhøffer, Mogens;


    , consisting of 17 normal mucosa and 66 adenocarcinoma samples. The transcriptional analysis revealed an unchanged expression level in areas with intact copy number, including regions with uniparental disomy, and a reduced expression level in the LOH regions representing factual losses (including 5q, 8p and 17......) and lymph node metastasis status (gain of 7q and 13q). Another subset of the identified alterations was shown to represent intratumor heterogeneity. In conclusion, we demonstrate that uniparental disomy is frequent in CRC, and identify genomic alterations associated with TP53 inactivation and lymph node...... LOH regions showed no evidence of a reduced copy number, indicating the presence of uniparental structures. The distribution of these structures was non-random, primarily involving 8q, 13q and 20q. This finding was supported by analysis of an independent set of array-based transcriptional profiles...

  7. Personality Profiles and Frequent Heavy Drinking in Young Adulthood. (United States)

    Zhang, Jieting; Bray, Bethany C; Zhang, Minqiang; Lanza, Stephanie T


    Few studies examining the link between personality and alcohol use have adopted a comprehensive modeling framework to take into account individuals' profiles across multiple personality traits. In this study, latent profile analysis (LPA) was applied to a national sample of young adults in the United States to identify subgroups defined by their profiles of mean scores on the Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness personality factors. Personality profiles were then used to predict heavy drinking. Five profiles were identified: Reserved, Rigid, Confident, Ordinary, and Resilient. Compared to individuals in the Ordinary profile, those with Reserved and Resilient profiles were at increased risk of frequent heavy drinking. These findings suggest which comprehensive personality profiles may place individuals at risk for problematic alcohol-related outcomes.

  8. Mining φ-Frequent Itemset Using FP-Tree

    Institute of Scientific and Technical Information of China (English)


    The problem of association rule mining has gained considerableprominence in the data mining community for its use as an important tool of knowledge discovery from large-scale databases. And there has been a spurt of research activities around this problem. However, traditional association rule mining may often derive many rules in which people are uninterested. This paper reports a generalization of association rule mining called φ-association rule mining. It allows people to have different interests on different itemsets that are the need of real application. Also, it can help to derive interesting rules and substantially reduce the amount of rules. An algorithm based on FP-tree for mining φ-frequent itemset is presented. It is shown by experiments that the proposed method is efficient and scalable over large databases.

  9. Frequent itemsets mining for database auto-administration

    CERN Document Server

    Aouiche, Kamel; Gruenwald, Le


    With the wide development of databases in general and data warehouses in particular, it is important to reduce the tasks that a database administrator must perform manually. The aim of auto-administrative systems is to administrate and adapt themselves automatically without loss (or even with a gain) in performance. The idea of using data mining techniques to extract useful knowledge for administration from the data themselves has existed for some years. However, little research has been achieved. This idea nevertheless remains a very promising approach, notably in the field of data warehousing, where queries are very heterogeneous and cannot be interpreted easily. The aim of this study is to search for a way of extracting useful knowledge from stored data themselves to automatically apply performance optimization techniques, and more particularly indexing techniques. We have designed a tool that extracts frequent itemsets from a given workload to compute an index configuration that helps optimizing data acce...

  10. Influence of frequent nocturnal home hemodialysis on food preference. (United States)

    Ipema, Karin; Franssen, Casper; van der Schans, Cees; Smit, Lianne; Noordman, Sabine; Haisma, Hinke


    Dialysis patients frequently report a change of taste that is reversible after renal transplantation, suggesting that uremic toxins may negatively influence taste. Currently, frequent nocturnal home hemodialysis (NHHD) is the most effective method of hemodialysis, and is associated with the lowest levels of uremic toxins. We studied preferences for various foods as an indicator of taste perception. We questioned whether food preference differs between NHHD patients and those on conventional hemodialysis. In this transverse, cross-sectional pilot study, we assessed food preference by means of a questionnaire for patients on NHHD (n=6; 8 hours of dialysis per night, for 5 or 6 nights a week) and 3 age-matched and sex-matched control groups: chronic home hemodialysis patients (HHD; n=9; 4 to 5 hours of dialysis per day, 3 days a week), chronic in-center hemodialysis patients (CHD; n=18; 4 to 5 hours of dialysis per day, 3 days a week), and healthy control subjects (HC; n=23). Mean scores for food preference did not differ between groups (P=.32). Similarly, the preference for product groups did not differ between groups. On an individual product level, we found only minor differences. The NHHD patients had a preference for savory snacks, as did the HC and CHD groups, whereas the HHD group had a preference for sweet snacks (P food preference. The change in taste reported by NHHD patients is not related to their particular food preferences. Copyright (c) 2010 National Kidney Foundation, Inc. Published by Elsevier Inc. All rights reserved.

  11. Ganglion Cells Are Frequently Present in Pediatric Mucosal Colorectal Biopsies. (United States)

    Kovach, Alexandra E; Pacheco, M Cristina


    Hirschsprung disease (HD) rarely presents as chronic constipation after the newborn period. At our institution, calretinin immunohistochemistry (CAL) is frequently requested by clinicians on rectal mucosal biopsies (RMBs) taken during colonoscopy in older children in whom suspicion for HD is low. We hypothesized that review of these biopsies would frequently reveal ganglion cells (GCs). We reviewed features of mucosal biopsies (November 2013 to September 2015) from children ≥1 year of age on which clinicians had requested CAL on at least one specimen. A total of 93 biopsies with paired CAL from 83 patients were suitable for study (ages 1-18 years, M:F 1.2). Submitted clinical indication was constipation in 62 patients (75%). GCs were found within or subjacent to muscularis mucosa in 63 biopsies (68%), 12 (19%) of which were designated from a specific anatomic site, eg, 2 or 3 cm. In 25 of 63 (40%) cases, GCs were identified on one of the first 3 sections (median 5th, range 1st-54th). Forty-six cases (73%) contained no or 1 mm of SM, and 21 (70%) had no SM. CAL was positive in 28 (93%) and equivocal/weak in 2 (7%); no additional work-up for HD was pursued. The data suggest that H&E sections of RMBs can exclude HD at a specified site in many cases and provide the basis for a future study examining the utility of CAL in RMBs without SM as a means for excluding HD.

  12. Gastrocnemius tendinosis--A frequent finding on MRI knee examination. (United States)

    Jawahar, Anugayathri; Lu, Yanan; Okur, Gokcan; Kliethermes, Stephanie; Lomasney, Laurie


    Gastrocnemius tendinosis (GT) is one potential cause for posterior knee pain, commonly overlooked on clinical examinations and imaging. This study assesses the frequency of GT on MR imaging in a convenience sample based on a database search and associations with other articular pathologies and clinical findings. With IRB approval, retrospective review was completed on 300 randomly selected MR knee exams performed from February 2009 to June 2010. Following de-identification, axial T2 and sagittal PD images, with or without fat suppression, were reviewed by 2 radiologists. The gastrocnemius tendon femoral attachments were graded as normal, mild (few cysts, thickening, intermediate signal) or severe GT (multiple cysts, marrow edema, tear). Select associated MR findings of internal derangement were documented. Clinical charts were reviewed for clinical presentation, physical exam findings, and select demographics. The inter-observer reliability for presence/grading of GT was very high (kappa statistic=0.97). Frequency of GT was 50.33%, most frequently involving medial head of gastrocnemius (63.6%). Grades of GT were 41.7% and 17.2% for mild and severe respectively. Univariate analysis showed statistically significant relationship between grade of GT with arthrosis (p=0.05) and clinical joint effusion (p=0.02). Multivariate analysis showed higher odds of severe GT for individuals with medial plus lateral GT. Statistical significance was noted for presence of both GT and ACL tear (13.9%; p=0.02). Significant findings of our analysis included GT presented with predominant involvement of medial head of gastrocnemius tendon, mild in severity, strong association with ACL tear, presented frequently as posterior knee pain, limited joint motion and clinical joint effusion. However, there was no statistically significant association between demographic features and medical comorbidities in the patients. Increased understanding of frequency of GT allows more accurate reporting of

  13. Tips for a physician in getting the right job, part XII: general questions for the applicant to ask. (United States)

    Harolds, Jay A


    The type and caliber of the questions asked by a job hunter is one of the ways an interviewer will evaluate the candidate. Questions that show poor preparation should not be asked, such as failure to read what the employer sent to the job seeker or not doing elementary research on the practice, the organization, or the community. Asking about insignificant details also is not helpful. Not having any good questions to ask is a negative in an interview. This article discusses many possible important questions for the applicant to ask during an interview.

  14. Epidemiology of frequent attenders: a 3-year historic cohort study comparing attendance, morbidity and prescriptions of one-year and persistent frequent attenders

    Directory of Open Access Journals (Sweden)

    ter Riet Gerben


    Full Text Available Abstract Background General Practitioners spend a disproportionate amount of time on frequent attenders. So far, trials on the effect of interventions on frequent attenders have shown negative results. However, these trials were conducted in short-term frequent attenders. It would be more reasonable to target intervention at persistent frequent attenders. Typical characteristics of persistent frequent attenders, as opposed to 1-year frequent attenders and non-frequent attenders, may generate hypotheses regarding modifiable factors on which new randomized trials may be designed. Methods We used the data of all 28,860 adult patients from 5 primary healthcare centers. Frequent attenders were patients whose attendance rate ranked in the (age and sex adjusted top 10 percent during 1 year (1-year frequent attenders or 3 years (persistent frequent attenders. All other patients on the register over the 3-year period were referred to as non-frequent attenders. The lists of medical problems coded by the GP using the International Classification of Primary Care (ICPC were used to assess morbidity. First, we determined which proportion of 1-year frequent attenders was still a frequent attender during the next two consecutive years and calculated the GPs' workload for these patients. Second, we compared morbidity and number of prescriptions for non-frequent attenders, 1-year frequent attenders and persistent frequent attenders. Results Of all 1-year frequent attenders, 15.4% became a persistent frequent attender equal to 1.6% of all patients. The 1-year frequent attenders (3,045; 10.6% were responsible for 39% of the face-to-face consultations; the 470 patients who would become persistent frequent attenders (1.6% were responsible for 8% of all consultations in 2003. Persistent frequent attenders presented more social problems, more psychiatric problems and medically unexplained physical symptoms, but also more chronic somatic diseases (especially diabetes

  15. A novel function of peroxiredoxin 1 (Prx-1) in apoptosis signal-regulating kinase 1 (ASK1)-mediated signaling pathway. (United States)

    Kim, So Yong; Kim, Tae Jin; Lee, Ki-Young


    We report a novel function of peroxiredoxin-1 (Prx-1) in the ASK1-mediated signaling pathway. Prx-1 interacts with ASK1 via the thioredoxin-binding domain of ASK1 and this interaction is highly inducible by H2O2. However, catalytic mutants of Prx1, C52A, C173A, and C52A/C173A, could not undergo H2O2 inducible interactions, indicating that the redox-sensitive catalytic activity of Prx-1 is required for the interaction with ASK1. Prx-1 overexpression inhibited the activation of ASK1, and resulted in the inhibition of downstream signaling cascades such as the MKK3/6 and p38 pathway. In Prx-1 knockdown cells, ASK1, p38, and JNK were quickly activated, leading to apoptosis in response to H2O2. These findings suggest a negative role of Prx-1 in ASK1-induced apoptosis.

  16. Survey-related experiential and attitudinal correlates of future health survey participation: results of a statewide survey. (United States)

    Beebe, Timothy J; Jenkins, Sarah M; Anderson, Kari J; Davern, Michael E


    To determine the survey-related experiential and attitudinal correlates of future health-related survey participation. From July 21, 2005, through October 25, 2005, we conducted a mixed-mode mail and telephone survey of 1636 noninstitutionalized Minnesota residents aged 18 years or older. The overall response rate was 49%. We examined the unadjusted effect of each independent variable on the likelihood of future participation in health-related surveys using univariate logistic regression and discerned the relative contribution of the different variables with multivariate logistic regression analysis. Respondents were asked to complete an average of 4.5 different surveys in the year before the current survey; approximately a quarter of the respondents perceived these surveys to be burdensome. The likelihood of future participation in health-related surveys was negatively related to good health status, a busy schedule, and perceptions that the surveys were too long. Respondents were more than twice as likely to indicate that they would participate in a future health-related survey if they knew the organization doing the survey. For health-related surveys, investigators should remain mindful of people's busy schedules and keep their surveys as short as possible. Further research is needed to clarify whether the decision to participate in a survey hinges more on knowing the organization paying to have a survey performed (the sponsor) or the survey vendor collecting the data.

    Dufresne, R J; Leonard, W J; Mestre, J P


    The ASK-IT/Assessing-to-Learn (A2L) project is an attempt to bring a strategic approach to learning, instruction, and communication. ASK-IT/A2L seeks to integrate formative assessment and classroom response system use with physics instruction at both the high school and college levels. In this guide, we present a structure for discussing the new mindset students need in an ASK-IT/A2L classroom, consisting of twelve "habits of mind" for students to develop. To help teachers plan instruction, we present a model of five stages of cognitive development that most students need to follow to develop desirable knowledge and skills. We show how a typical lesson might be organized around "items," the smallest unit of ASK-IT/A2L lesson planning: questions, problems, or tasks given to students to work on individually or in groups. To help with item creation, we present our model-based design paradigm and suggest tips for avoiding common pitfalls and ways to match up cognitive goals with habits of mind. Finally, we apply ...

  19. Low-cost coherent UDWDM-PON by hybrid DBPSK/ASK-2 modulation (United States)

    Li, Yuan; Deng, Zhuanhua; Hu, Rong; li, Cai; Li, Wei; Yuan, Zhilin; Yu, Shaohua


    The coherent ultra-dense wavelength division multiplexed passive optical network (UDWDM-PON) has been widely studied recently, in which the envelop detection based coherent reception of on-off keying (OOK) signal has been shown to possess both high receiver sensitivity and tolerance against laser linewidth/chirp. In order to increase the spectral efficiency (SE) to 2 bit/s/Hz, researchers formulated a hybrid DBPSK/ASK-2 modulation using the silicon Mach-Zehnder modulator (MZM), where both amplitude and phase modulation are employed. The experimental result shows that the proposed DBPSK/ASK-2 modulation is of better performance than PAM-4 at the same SE of 2 bit/s/Hz. When the low-cost silicon MZM and DFB laser of 4-MHz linewidth are employed, the receiver sensitivity of DBPSK/ASK-2 exceeds that of the PAM-4 by about 5.7 dB. This work can achieve about -46 dBm receiver sensitivity at 2.5 GBaud after transmission over 80-km standard single mode fiber (SSMF). The proposed DBPSK/ASK-2 modulation using low-cost silicon MZM and DFB laser is considered as a practical and reliable method for the future UDWDM-PON at the SE of 2 bit/s/Hz.

  5. Implementing Ask Me 3 to improve African American patient satisfaction and perceptions of physician cultural competency. (United States)

    Michalopoulou, Georgia; Falzarano, Pamela; Arfken, Cynthia; Rosenberg, David


    Improve African American patient satisfaction and perceptions of physician cultural competency through the implementation of Ask Me 3 pamphlet which encourages patients to ask questions of physicians. Intervention participants received the pamphlet prior to their visit with the physician. Analysis evaluated differences in patient satisfaction and perceptions of physician cultural competency between intervention participants and controls. Intervention participants who saw their regular physician reported higher satisfaction. All found the questions to be helpful and reported knowing more about their medical condition or illness after the visit. The Ask Me 3 pamphlet is a low cost and logistically feasible tool that could be readily implemented in medical settings to facilitate physician-patient interaction. Improved satisfaction with the visit was found when the pamphlet was implemented during visits with a regular physician. Thus, our research findings suggest implementation of the Ask Me 3 pamphlet has the potential to improve health care behaviors and health outcomes and may ultimately lead to a reduction in health care disparities.

  7. Bid-Ask Spreads, Trading Volume and Return Volatility: Intraday Evidence from Indian Stock Market

    Directory of Open Access Journals (Sweden)

    Rashmi Ranjan Paital


    Full Text Available This paper empirically examines the relationship between stock return volatility, trading volume and bid-ask spread within the scope of mixture of distribution hypothesis (MDH and sequential information arrival hypothesis (SIAH in the Indian stock market using high frequency 5-minute data set over the period of 2 July 2012 to 31 December 2012. This is the first kind of study in India using bid-ask spread as an additional information variable along with trading volume to investigate the relationship with stock return volatility. Our empirical findings provide evidence of a positive contemporaneous relationship between return volatility and trading volume, and also between return volatility and bid-ask spread. Moreover, the results of Granger causality test show that the information content of trading volume and bid-ask spread are useful for predicting stock return volatility. Our results indicate that information arrival to investors tends to follow a sequential rather than a simultaneous process. This finding is consistent with the sequential information arrival hypothesis and contradicts the mixture of distribution hypothesis.

    Rukiye Aydın FEBO


    Full Text Available Objectives: To compare the level of conjunctival changes using conjunctival impression cytology in wearers of frequent replacement hydrogel (FRHL and frequent replacement silicone hydrogel contact lens FRSHL. Materials and Methods: Forty-two contact lens users who were seen at the Cornea and Contact Lens Unit, Department of Ophthalmology, Dokuz Eylül University were evaluated in this study. The first group consisted of wearers of FRHL used for minimum one year and maximum five years. The second group consisted of wearers who used FRSHL for minimum one year and maximum 5 years. Twenty healthy individuals with no contact lens history were included in the control group. Conjunctival impression cytology was applied to all contact lens users and the control group in order to evaluate the conjunctival changes, and the results of impression cytology were graded by the Nelson’s method. Results: In the comparison of the groups according to impression cytology scoring, there was no difference between the users of FRHL and FRSHL. Similar amounts of squamous metaplasia and goblet cell loss were encountered in both groups. Nonetheless, impression cytology grading was significantly lower in the control group than in the other two groups. Conclusion: In conclusion, the use of FRHL and FRSHL for over a year causes some histological changes in the conjunctiva such as squamous metaplasia and goblet cell loss eventually leading to dry eye symptoms. However, no differences were determined between FRHL and FRSHL users with regard to severity of conjunctival changes. (Turk J Ophthalmol 2014; 44: 47-52

  10. ASK1 Inhibitor Halts Progression of Diabetic Nephropathy in Nos3-Deficient Mice. (United States)

    Tesch, Greg H; Ma, Frank Y; Han, Yingjie; Liles, John T; Breckenridge, David G; Nikolic-Paterson, David J


    p38 mitogen-activated protein kinase (MAPK) signaling promotes diabetic kidney injury. Apoptosis signal-regulating kinase (ASK)1 is one of the upstream kinases in the p38 MAPK-signaling pathway, which is activated by inflammation and oxidative stress, suggesting a possible role for ASK1 in diabetic nephropathy. In this study, we examined whether a selective ASK1 inhibitor can prevent the induction and progression of diabetic nephropathy in mice. Diabetes was induced in hypertensive endothelial nitric oxide synthase (Nos3)-deficient mice by five low-dose streptozotocin (STZ) injections. Groups of diabetic Nos3(-/-) mice received ASK1 inhibitor (GS-444217 delivered in chow) as an early intervention (2-8 weeks after STZ) or late intervention (weeks 8-15 after STZ). Control diabetic and nondiabetic Nos3(-/-) mice received normal chow. Treatment with GS-444217 abrogated p38 MAPK activation in diabetic kidneys but had no effect upon hypertension in Nos3(-/-) mice. Early intervention with GS-444217 significantly inhibited diabetic glomerulosclerosis and reduced renal dysfunction but had no effect on the development of albuminuria. Late intervention with GS-444217 improved renal function and halted the progression of glomerulosclerosis, renal inflammation, and tubular injury despite having no effect on established albuminuria. In conclusion, this study identifies ASK1 as a new therapeutic target in diabetic nephropathy to reduce renal inflammation and fibrosis independent of blood pressure control. © 2015 by the American Diabetes Association.

    袁鼎荣; 张师超


    The problem of mining frequent set is a key issue in data mining. In this paper, a new method of miningfrequent set based on the frequent link is proposed. The algorithm constructs alternate frequent link from the transac-tion, the alternate link is yielded by adding up the alternate frequent link which constructed by scanning the transac-tion database in proper order. The frequent link that comprises all the information is constructed with the frequentnode which is selected according requirement. Our algorithm need to scan the transaction database only once and easysupervises the change of frequent set in order to guarantee the right of association rule.

    Pedro Magalhães


    Full Text Available Chest pain is one of the most frequent patient’s complaints. The commonest underlying causes are well known, but, sometimes, in some clinical scenarios, it is necessary to consider other diagnoses. We report a case of a 68-year-old Caucasian male, chronically hypertensive, who complained of recurrent episodes of chest pain and fever with elevated acute phase reactants. The first investigation was negative for some of the most likely diagnosis and he quickly improved with anti-inflammatory drugs. Over a few months, his symptoms continued to recur periodically, his hypertension was aggravated, and he developed headaches and lower limbs claudication. After a temporal artery biopsy that was negative for vasculitis, he underwent a positron emission tomography suggestive of Takayasu Arteritis. Takayasu Arteritis is a rare chronic granulomatous vasculitis of the aorta and its first-order branches affecting mostly females up to 50 years old. Chest pain is experienced by >40% of the patients and results from the inflammation of the aorta, pulmonary artery, or coronaries.

  14. Gnathostomiasis in a patient who frequently consumes sushi. (United States)

    Jarell, Abel D; Dans, Michael J; Elston, Dirk M; Mathison, Blaine A; Ruben, Beth S


    A 45-year-old woman presented for evaluation of a solitary pruritic nodule on the abdomen that suddenly appeared 3 weeks before. She was healthy without a significant medical history, travel history, exposures, medications, or pets. She reported that she consumed sushi at least weekly in the city of San Francisco. A punch biopsy revealed a superficial and deep perivascular and interstitial infiltrates consisting of lymphocytes, plasma cells, and many eosinophils. Most notably, there was a parasite centered in the reticular dermis with prominent lateral chords, a well-developed muscular esophagus, and an intestine that contained a brush border and multinucleate cells. Evaluation of these histological sections by the Centers for Disease Control and Prevention determined the parasite to be a nematode of the genus Gnathostoma. The patient underwent a systemic work-up for gnathostomiasis, including imaging, and no other abnormalities were found. She completed a 3-week course of albendazole and has remained asymptomatic since the biopsy of her abdominal lesion. Although gnathostomiasis is often a systemic illness, this patient did well with apparently only localized cutaneous disease. Gnathostomiasis should be considered in patients who present with nonspecific papules and nodules, especially when there is a history of frequent consumption of raw fish.

  15. Salt tolerance evolves more frequently in C4 grass lineages. (United States)

    Bromham, L; Bennett, T H


    Salt tolerance has evolved many times in the grass family, and yet few cereal crops are salt tolerant. Why has it been so difficult to develop crops tolerant of saline soils when salt tolerance has evolved so frequently in nature? One possible explanation is that some grass lineages have traits that predispose them to developing salt tolerance and that without these background traits, salt tolerance is harder to achieve. One candidate background trait is photosynthetic pathway, which has also been remarkably labile in grasses. At least 22 independent origins of the C4 photosynthetic pathway have been suggested to occur within the grass family. It is possible that the evolution of C4 photosynthesis aids exploitation of saline environments, because it reduces transpiration, increases water-use efficiency and limits the uptake of toxic ions. But the observed link between the evolution of C4 photosynthesis and salt tolerance could simply be due to biases in phylogenetic distribution of halophytes or C4 species. Here, we use a phylogenetic analysis to investigate the association between photosynthetic pathway and salt tolerance in the grass family Poaceae. We find that salt tolerance is significantly more likely to occur in lineages with C4 photosynthesis than in C3 lineages. We discuss the possible links between C4 photosynthesis and salt tolerance and consider the limitations of inferring the direction of causality of this relationship.

  16. Determining frequent patterns of copy number alterations in cancer.

    Directory of Open Access Journals (Sweden)

    Franck Rapaport

    Full Text Available Cancer progression is often driven by an accumulation of genetic changes but also accompanied by increasing genomic instability. These processes lead to a complicated landscape of copy number alterations (CNAs within individual tumors and great diversity across tumor samples. High resolution array-based comparative genomic hybridization (aCGH is being used to profile CNAs of ever larger tumor collections, and better computational methods for processing these data sets and identifying potential driver CNAs are needed. Typical studies of aCGH data sets take a pipeline approach, starting with segmentation of profiles, calls of gains and losses, and finally determination of frequent CNAs across samples. A drawback of pipelines is that choices at each step may produce different results, and biases are propagated forward. We present a mathematically robust new method that exploits probe-level correlations in aCGH data to discover subsets of samples that display common CNAs. Our algorithm is related to recent work on maximum-margin clustering. It does not require pre-segmentation of the data and also provides grouping of recurrent CNAs into clusters. We tested our approach on a large cohort of glioblastoma aCGH samples from The Cancer Genome Atlas and recovered almost all CNAs reported in the initial study. We also found additional significant CNAs missed by the original analysis but supported by earlier studies, and we identified significant correlations between CNAs.

  17. Hypervascularity is more frequent in medullary thyroid carcinoma (United States)

    Lai, Xingjian; Liu, Meijuan; Xia, Yu; Wang, Liang; Bi, Yalan; Li, Xiaoyi; Zhang, Bo; Yang, Meng; Dai, Qing; Jiang, Yuxin


    Abstract This study was designed to retrospectively compare the sonographic features of medullary thyroid carcinoma (MTC) and the features of papillary thyroid carcinoma (PTC). A total of 97 patients with 127 MTCs between January 2000 and January 2016 and 107 consecutive patients with 132 PTCs were included in this study. Two radiologists retrospectively determined the sonographic features and compared the findings of MTCs and PTCs. Compared with the patients with PTCs, the patients with MTCs were older (46.9 years vs 42.9 years, P = 0.016) and the male proportion was higher (53.6% vs 33.6%, P = 0.005). Most of the MTCs had an irregular shape (72.4%), a length/width ratio hypoechogenicity (96.9%), heterogeneous echotexture (76.4%), no cystic change (78.7%), calcification (63.8%), and hypervascularity (72.4%). There was no significant difference in the boundary, peripheral halo ring, echogenicity, and calcification between the MTCs and PTCs. However, compared with the PTCs, a larger size (2.2 vs 1.2 cm, P hypoechogenicity, the presence of microcalcifications, and increased intranodular vascularity. However, MTCs tend to possess these suspicious sonographic features less often than PTCs, with the exception of hypervascularity, which was more frequent in MTCs. PMID:27930537

  19. Evidence and Implications of Frequent Fires in Ancient Shrub Tundra

    Energy Technology Data Exchange (ETDEWEB)

    Higuera, P E; Brubaker, L B; Anderson, P M; Brown, T A; Kennedy, A T; Hu, F S


    Understanding feedbacks between terrestrial and atmospheric systems is vital for predicting the consequences of global change, particularly in the rapidly changing Arctic. Fire is a key process in this context, but the consequences of altered fire regimes in tundra ecosystems are rarely considered, largely because tundra fires occur infrequently on the modern landscape. We present paleoecological data that indicate frequent tundra fires in northcentral Alaska between 14,000 and 10,000 years ago. Charcoal and pollen from lake sediments reveal that ancient birchdominated shrub tundra burned as often as modern boreal forests in the region, every 144 years on average (+/- 90 s.d.; n = 44). Although paleoclimate interpretations and data from modern tundra fires suggest that increased burning was aided by low effective moisture, vegetation cover clearly played a critical role in facilitating the paleo-fires by creating an abundance of fine fuels. These records suggest that greater fire activity will likely accompany temperature-related increases in shrub-dominated tundra predicted for the 21st century and beyond. Increased tundra burning will have broad impacts on physical and biological systems as well as land-atmosphere interactions in the Arctic, including the potential to release stored organic carbon to the atmosphere.

  20. [Frequent causes of diarrhea: celiac disease and lactose intolerance]. (United States)

    Jankowiak, Carsten; Ludwig, Diether


    Celiac disease and lactose intolerance are both relatively frequent diseases with symptoms occurring after ingestion of certain food components. In celiac disease wheat gluten and related proteins of other cereals induce an inflammatory disease of the small intestine in predisposed individuals, leading to gastrointestinal and extraintestinal symptoms. Moreover, there is an association with many other diseases and besides classic symptoms (diarrhea, weight loss, malabsorption) atypical courses with less or lacking gastrointestinal symptoms exist. The prevalence is about 1 : 100 (Europe, USA) and higher than supposed earlier. Diagnostic criteria include serologic tests (tissue transglutaminase antibody, endomysial antibody) and characteristic small bowel histology (lymphocytic infiltration, villous atrophy). Therapy is a strict and lifelong gluten-free diet. Rarely, refractory disease or lack of compliance are associated with increased risk of malignancy and worse prognosis. Lactose intolerance is attributed to low intestinal lactase levels, due to reduced genetic expression or mucosal injury and consequent intolerance to dairy products. The frequency is varying in different ethnic groups, occurring in 10-15% of Northern European people. Intensity of clinical symptoms (diarrhea, abdominal pain, bloating) depends on the amount of ingested lactose and individual activity of intestinal lactase. The capacity of lactose malabsorption can be measured using the noninvasive lactose breath hydrogen test. The treatment is based on a reduced dietary lactose intake or in case of secondary form treatment of the underlying disease.

    To clarify the semiology of febrile seizures (FS) and to determine the frequency of FS with symptoms suggestive of focal onset. FS symptoms in children were reported within 24h of seizure onset by the parents using a structured questionnaire consisting principally of closed-ended questions. We focused on events at seizure commencement, including changes in behavior and facial expression, and ocular and oral symptoms. We also investigated the autonomic and motor symptoms developing during seizures. The presence or absence of focal and limbic features was determined for each patient. The associations of certain focal and limbic features with patient characteristics were assessed. Information was obtained on FS in 106 children. Various events were recorded at seizure commencement. Behavioral changes were observed in 35 children, changes in facial expression in 53, ocular symptoms in 78, and oral symptoms in 90. In terms of events during seizures, autonomic symptoms were recognized in 78, and convulsive motor symptoms were recognized in 68 children. Focal features were evident in 81 children; 38 children had two or more such features. Limbic features were observed in 44 children, 9 of whom had two or more such features. There was no significant relationship between any patient characteristic and the numbers of focal or limbic features. The semiology of FS varied widely among children, and symptoms suggestive of focal onset were frequent. FS of focal onset may be more common than is generally thought. Copyright © 2017 Elsevier Inc.

  2. Frequent gain and loss of functional transcription factor binding sites.

    Directory of Open Access Journals (Sweden)

    Scott W Doniger


    Full Text Available Cis-regulatory sequences are not always conserved across species. Divergence within cis-regulatory sequences may result from the evolution of species-specific patterns of gene expression or the flexible nature of the cis-regulatory code. The identification of functional divergence in cis-regulatory sequences is therefore important for both understanding the role of gene regulation in evolution and annotating regulatory elements. We have developed an evolutionary model to detect the loss of constraint on individual transcription factor binding sites (TFBSs. We find that a significant fraction of functionally constrained binding sites have been lost in a lineage-specific manner among three closely related yeast species. Binding site loss has previously been explained by turnover, where the concurrent gain and loss of a binding site maintains gene regulation. We estimate that nearly half of all loss events cannot be explained by binding site turnover. Recreating the mutations that led to binding site loss confirms that these sequence changes affect gene expression in some cases. We also estimate that there is a high rate of binding site gain, as more than half of experimentally identified S. cerevisiae binding sites are not conserved across species. The frequent gain and loss of TFBSs implies that cis-regulatory sequences are labile and, in the absence of turnover, may contribute to species-specific patterns of gene expression.

  3. Sampling circulating tumor cells for clinical benefits: how frequent? (United States)

    Leong, Sai Mun; Tan, Karen M L; Chua, Hui Wen; Tan, Doreen; Fareda, Delly; Osmany, Saabry; Li, Mo-Huang; Tucker, Steven; Koay, Evelyn S C


    Circulating tumor cells (CTCs) are cells shed from tumors or metastatic sites and are a potential biomarker for cancer diagnosis, management, and prognostication. The majority of current studies use single or infrequent CTC sampling points. This strategy assumes that changes in CTC number, as well as phenotypic and molecular characteristics, are gradual with time. In reality, little is known today about the actual kinetics of CTC dissemination and phenotypic and molecular changes in the blood of cancer patients. Herein, we show, using clinical case studies and hypothetical simulation models, how sub-optimal CTC sampling may result in misleading observations with clinical consequences, by missing out on significant CTC spikes that occur in between sampling times. Initial studies using highly frequent CTC sampling are necessary to understand the dynamics of CTC dissemination and phenotypic and molecular changes in the blood of cancer patients. Such an improved understanding will enable an optimal, study-specific sampling frequency to be assigned to individual research studies and clinical trials and better inform practical clinical decisions on cancer management strategies for patient benefits.

  4. Perceived recollection of frequent exposure to foods in childhood is associated with adulthood liking. (United States)

    Wadhera, Devina; Capaldi Phillips, Elizabeth D; Wilkie, Lynn M; Boggess, May M


    Food preferences and habits learned at a young age can influence adulthood dietary patterns and weight, but the mechanism remains to be elucidated. We investigated the effect of perceived recollections of early food experiences on current liking for those foods by 670 college students. We showed that the perceived recollection of frequent consumption of foods in childhood was significantly related to current liking for the vast majority of the foods, including nutritious foods such as vegetables. Similarly, parental encouragement and modeling was positively related with current liking, even for foods that were disliked in childhood. Additionally, perceived recollections of parental restriction or forced consumption were significantly negatively related with current liking. Lastly, we demonstrated that perceived recollections by college students of childhood eating practices were in moderate agreement with those of their parents, lending credibility to the retrospective survey methodology in determining long-term effects of exposure on current food habits. These findings show that the perceived recalled frequency of consumption of foods is one determinant of the food preferences of adults, demonstrating a long-term effect of frequency of exposure, a finding consistent with experimentally controlled short-term studies. Frequent exposure to foods in childhood could be a simple and effective way for parents and caregivers to instill healthy eating habits in children.

  5. Clinical Pharmacology of Frequently Used Intravenous Drugs During Bariatric Surgery in Adolescents. (United States)

    Vaughns, Janelle D; Ziesenitz, Victoria C; van den Anker, John N


    Obesity represents one of the most important public health issues according to the World Health Organization. Additionally, in a recent National Health and Nutrition Survey of 2011-2012, approximately 17 % of children and adolescents in the United States were considered obese. The obesity rate is higher within the adolescent age group as compared to preschool children. Childhood obesity is particularly problematic, because the co-morbid disease states which accompany obesity may require frequent pharmacotherapy and/ or surgical intervention. Despite the potential for increased pharmacotherapy among obese patients, there is a paucity of dosing guidelines for this special population. Optimal drug dosing in obese pediatric patients has not been sufficiently explored as the present data available are mostly specific for obese adults. In this review, we present an overview concerning what is currently known about the pharmacokinetics and pharmacogenetics of frequently used drugs including midazolam, fentanyl and its newer derivatives, morphine, ketamine, acetaminophen, dexmedetomidine and enoxaparin in obese adolescents undergoing bariatric surgery. We will also summarize the current dosing recommendations of anesthetic drugs in bariatric anesthesia.

  6. "They just asked me why I became homeless": "failure to ask" as a barrier to homeless women's ability to access services post-victimization. (United States)

    Huey, Laura; Broll, Ryan; Hryniewicz, Danielle; Fthenos, Georgios


    As "access brokers" to resources for their clients, homeless shelter workers are often in a position to aid victimized homeless women in securing medical and psychological services post-victimization. Given high rates of victimization within this population, we would expect that a routine part of a shelter's case management process would involve queries regarding victimization. Through in-depth qualitative interviews with 42 victimized homeless women in Chicago and Detroit, we sought to discover the extent to which such queries were pursued by staff at their current shelter. What we found is that women are seldom asked to provide a complete history that includes experiences of violent victimization and its effects. From these results, we make several recommendations aimed at improving homeless victims' access to services.

  7. Frequent underwater volcanism in the central Aegean Sea (United States)

    Huebscher, C.; Ruhnau, M.; Dehghani, G. A.


    The extinction of the Minoan culture in the mid second millennium BCE is a well known consequence of the Plinian eruption of Thera volcano (Santorini Island). Santorini is a member of the South Aegean arc forming a chain from the Gulf of Saronikos (Susaki, Egina, Poros, Methana) at West, to an area close to the Anatolian coast at East (Kos, Nisyros and minor islands), through the central part (Milos and Santorini island groups). Underwater volcanic activity was manifested historically only once. During 1649-1650 CE the Kolumbo underwater volcano evolved about 8 km northeast of Santorini. As a consequence of this eruption volcanic ash covered the entire Aegean area and a hazardous tsunami was triggered. Here we show by means of reflection seismic and magnetic data that underwater volcanism occurred more frequently in the central Aegean Sea than previously assumed. Seismic data show that Kolumbo constitutes of five vertically stacked cones of pyroclastic sediment plus at least four smaller cones on the flank of the volcano. The formation of Kolumbo started synchronous with Santorini Island. The entire volume of the Kolumbo pyroclastic cones is estimated to more than 15 cubic-kilometers. Several small-scale cones have been detected in the Anyhdros Basin some km north-east of Kolumbo, being previously interpreted as mud volcanoes by other authors. However, the similarity of seismic and magnetic signatures of these cones and Kolumbo strongly suggest that these cones were also created by underwater volcanism. Volcanic cones, Kolumbo and Santorini are situated along a NE-SW striking graben system that evolved during five extensional tectonic pulses in the Pliocene.

  8. Frequent occurrence of uniparental disomy in colorectal cancer. (United States)

    Andersen, Claus Lindbjerg; Wiuf, Carsten; Kruhøffer, Mogens; Korsgaard, Marianne; Laurberg, Søren; Ørntoft, Torben Falck


    We used SNP arrays to identify and characterize genomic alterations associated with colorectal cancer (CRC). Laser microdissected cancer cells from 15 adenocarinomas were investigated by Affymetrix Mapping 10K SNP arrays. Analysis of the data extracted from the SNP arrays revealed multiple regions with copy number alterations and loss of heterozygosity (LOH). Novel LOH areas were identified at chromosomes 13, 14 and 15. Combined analysis of the LOH and copy number data revealed genomic structures that could not have been identified analyzing either data type alone. Half of the identified LOH regions showed no evidence of a reduced copy number, indicating the presence of uniparental structures. The distribution of these structures was non-random, primarily involving 8q, 13q and 20q. This finding was supported by analysis of an independent set of array-based transcriptional profiles, consisting of 17 normal mucosa and 66 adenocarcinoma samples. The transcriptional analysis revealed an unchanged expression level in areas with intact copy number, including regions with uniparental disomy, and a reduced expression level in the LOH regions representing factual losses (including 5q, 8p and 17p). The analysis also showed that genes in regions with increased copy number (including 7p and 20q) were predominantly upregulated. Further analyses of the SNP data revealed a subset of the identified alterations to be specifically associated with TP53 inactivation (including 8q gain and 17p loss) and lymph node metastasis status (gain of 7q and 13q). Another subset of the identified alterations was shown to represent intratumor heterogeneity. In conclusion, we demonstrate that uniparental disomy is frequent in CRC, and identify genomic alterations associated with TP53 inactivation and lymph node status.

  9. 4SC-202 activates ASK1-dependent mitochondrial apoptosis pathway to inhibit hepatocellular carcinoma cells

    Energy Technology Data Exchange (ETDEWEB)

    Fu, Meili, E-mail: [Department of Infectious Disease, Linyi People' s Hospital, Linyi 276000 (China); Wan, Fuqiang [Department of Head and Neck Surgery, Linyi Tumor Hospital, Linyi 276000 (China); Li, Zhengling [Department of Nursing, Tengzhou Central People' s Hospital, Tengzhou 277500 (China); Zhang, Fenghua [Department of Operating Room, Linyi People' s Hospital, Linyi 276000 (China)


    The aim of the present study is to investigate the potential anti-hepatocellular carcinoma (HCC) cell activity by 4SC-202, a novel class I HDAC inhibitor (HDACi). The associated signaling mechanisms were also analyzed. We showed that 4SC-202 treatment induced potent cytotoxic and proliferation–inhibitory activities against established HCC cell lines (HepG2, HepB3, SMMC-7721) and patient-derived primary HCC cells. Further, adding 4SC-202 in HCC cells activated mitochondrial apoptosis pathway, which was evidenced by mitochondrial permeability transition pore (mPTP) opening, cytochrome C cytosol release and caspase-3/-9 activation. Inhibition of this apoptosis pathway, by caspase-3/-9 inhibitors, mPTP blockers, or by shRNA-mediated knockdown of cyclophilin-D (Cyp-D, a key component of mPTP), significantly attenuated 4SC-202-induced HCC cell death and apoptosis. Reversely, over-expression of Cyp-D enhanced 4SC-202's sensitivity in HCC cells. Further studies showed that 4SC-202 induced apoptosis signal-regulating kinase 1 (ASK1) activation, causing it translocation to mitochondria and physical association with Cyp-D. This mitochondrial ASK1-Cyp-D complexation appeared required for mediating 4SC-202-induced apoptosis activation. ASK1 stable knockdown by targeted-shRNAs largely inhibited 4SC-202-induced mPTP opening, cytochrome C release, and following HCC cell apoptotic death. Together, we suggest that 4SC-202 activates ASK1-dependent mitochondrial apoptosis pathway to potently inhibit human HCC cells. - Highlights: • 4SC-202 exerts potent anti-proliferative and cytotoxic activity against established/primary HCC cells. • SC-202-induced anti-HCC cell activity relies on caspase-dependent apoptosis activation. • 4SC-202 activates Cyp-D-dependent mitochondrial apoptosis pathway in HCC cells. • 4SC-202 activates ASK1 in HCC cells, causing it translocation to mitochondria. • Mitochondrial ASK1-Cyp-D complexation mediates 4SC-202's activity in HCC cells.

  12. Association of frequent use of food labels with weight loss behaviors among low-income reproductive-age women. (United States)

    Laz, Tabassum H; Rahman, Mahbubur; Berenson, Abbey B


    To examine whether frequent use of food labels is associated with weight loss behaviors among low-income reproductive-age women. A self-administered survey of 1245 women aged 16 to 40 years assessed the frequency of food label use and weight loss behaviors during the past 12 months. Multivariate logistic regression analyses were performed to examine the association between frequent use of food labels and weight loss behaviors after adjusting for confounders. Overall, 10.4% to 19.6% of women frequently used food labels to obtain information on different sections (ingredient list, nutrient claims, nutrition panel, serving size, or health claims), dietary components (calories, total fat, saturated fat, cholesterol, sodium/salt, fiber, sugar, vitamins, or minerals), and food products (desserts, snacks, frozen dinners, cereals, salad dressings, table spreads, or raw/processed meat). Women who used food labels frequently were more likely to engage in healthy weight loss behaviors compared to those who used them infrequently or did not use them at all. For example, the odds ratios (OR) and 95% confidence interval (CI) of "began to exercise/exercised more" for the 3 categories of food label use mentioned above were 2.24 and 1.65-3.04; 2.52 and 1.90-3.32; and 1.85 and 1.36-2.52, respectively. The odds of healthy weight loss behaviors were 2 to 4 times higher when food labels were used frequently to seek information on calories and nutrients such as total fat, saturated fat, or cholesterol. However, frequent food label users were also more likely to practice a few unhealthy weight loss behaviors, such as taking diet pills, medicines, herbs, or supplements without a prescription. Frequent use of food labels was associated with increased healthy weight loss behaviors among reproductive-age women, which can be incorporated into obesity preventive strategies with distinct awareness regarding unhealthy weight loss behaviors.

  13. Skin-lightening cosmetics: frequent, potentially severe adverse effects. (United States)


    Skin-lightening cosmetics are used by many women and men around the world. The products contain a variety of substances, which are often unknown to the users. Most of these products include topical corticosteroids, hydroquinone and mercury salts. Many other substances may be added. Several surveys and cohort studies, including several thousand individuals, have shown that regular application of skin-lightening cosmetics to large surface areas can have irreversible cutaneous adverse effects, such as patchy hyper- or hypopigmentation, skin atrophy, stretch marks and delayed wound healing, and can also mask or, on the contrary, promote or reactivate skin infections. Cases of skin cancer have been attributed to skin-lightening cosmetics. A Senegalese cohort study of 147 women showed a statistically significant increase in the risk of hypertension and diabetes linked to the use of skin-lightening agents. Other systemic adverse effects attributed to skin-lightening cosmetics include Cushing's syndrome, adrenal insufficiency, nephrotic syndrome, neurological disorders, and ocular disorders. Hypersensitivity reactions, including anaphylaxis, have also been attributed to these products. Many skin-lightening cosmetics contain substances that can harm the unborn child. For example, tretinoin is teratogenic while salicylic acid is feto-toxic. In practice, users are often unaware of the risk of severe adverse effects associated with skin-lightening cosmetics. Users should be informed of these adverse effects and encouraged to stop using these products, especially when skin disorders appear.

  14. What can we learn about postnatal care in Ghana if we ask the right questions? A qualitative study

    Directory of Open Access Journals (Sweden)

    Zelee Hill


    Full Text Available Background: There are increasing efforts to monitor progress in maternal and neonatal care, with household surveys the main mode of data collection. Postnatal care (PNC is considered a priority indicator yet few countries report on it, and the need to improve the construct validity associated with PNC questions is recognized. Objectives: To determine women's knowledge of what happens to the baby after delivery, women's comprehension of terms and question phrasing related to PNC, and issues with recall periods. Design: Forty qualitative interviews and four focus group discussions were conducted with mothers, and 10 interviews with health workers in rural Ghana. Data were collected on knowledge and recall of postnatal health checks and language used to describe these health checks. Results: Mothers required specific probing using appropriate language to report postnatal checks. They only had adequate knowledge of postnatal checks, which were easily observed or required asking them a question. Respondents reported that health workers rarely communicated with mothers about what they were doing, and most women did not know the purpose of the equipment used during health checks, such as why a thermometer was being used. Knowledge of neonatal checks in the first hours after a facility delivery was low if the mother and child were separated, or if the mother was tired or weak. Many women reported that they could remember events clearly, but long recall periods affected reporting for some, especially those who had multiple checks or for those with no problems. Conclusions: Direct questions about PNC or health checks are likely to underestimate coverage. Validity of inferences can be enhanced by using appropriate verbal probes during surveys on commonly performed checks that are clear and visible to the mother.

  15. Amplitude distribution of ionization jerks in ionization-chamber ASK-1 according long-term measurements (United States)

    Timofeev, Vladislav


    As part of the Yakut complex systems by measuring the intensity of cosmic rays has a unique device spherical - ionization chamber ASK-1 with a lead screen thickness of 12 cm. The camera allows you to explore the physical characteristics of the so-called "ionization jerks " - sharp increases ionization current caused by the passage through the device much ionizing particles of cosmic origin. Due to a large increase in current nuclear cascade "showers", formed mainly by particles of cosmic rays in the camera screen. Over the entire period of observation (50 years old) camera ASK-1 was registered 59125 aftershocks. Their nature and properties still does not sufficiently studied, especially in medium and large amplitudes.

  16. The rise of repeal: policy entrepreneurship and Don't Ask, Don't Tell. (United States)

    Neff, Christopher L; Edgell, Luke R


    We report on policy entrepreneurship by Servicemembers Legal Defense Network (SLDN) and how its legislative strategies used mini-windows of opportunity to shift Capitol Hill perspectives of Don't Ask, Don't Tell (DADT) from political plutonium to an emerging issue requiring a second look. Four phases in the legislative history of DADT are identified: radioactive, contested, emerging, and viable. In all, this article argues that SLDN's entrepreneurship focused on contesting congressional sensibilities to wait or defer on repeal, maintained that every discharge was damaging and transitioned toward a post-repeal mind set. Finally, we illustrate the importance of these transitions by comparing SLDN's 2004 estimated vote count for the introduction of the Military Readiness Enhancement Act with the final 2010 voting results on the Don't Ask, Don't Tell Repeal Act.

    Zhou, Qirui; Ma, Jun; Lu, Yang; Huang, Lingchen; Chen, Biao


    A novel evolution scheme from legacy TDM-PON to the next generation WDM-PON with DPSK/ASK orthogonal modulation is proposed. The new WDM-PON is added into the existing PON infrastructure and coexisting with the current TDM-PON. To eliminate any change requirement for the existing TDM-PON, DPSK is applied for WDM-PON downstream. Meanwhile, upstream remodualtion is applied to achieve colorless ONU in WDM-PON. The application of DPSK/ASK reduces both crosstalk from coexisting and remodulation. The experiment results show the crosstalk is very little. Good performance is achieved for both unchanged coexisting TDM-PON and WDM-PON upstream signals in our proposed scheme.

    Full Text Available Background: Some coincidental disorders with migrainehave been introduced that may have role in itspathogenesis or aggravation. In this study we determinedthe relative frequency of hyperlipidemia as a coincidentaldisorder in patients affected by migraine.Methods: A total of 102 migraine-affected patientsaccording to International Headache Society (HIS criteriaand 103 control subjects adjusted for age participated inthis case-control study. Their serum level of triglyceride,total cholesterol, low density lipoprotein cholesterol (LDL-Cand high density lipoprotein cholesterol (HDL-C weremeasured.Results: A total of 84 women and 18 men with mean age of34.9 ± 11.8 years and 79 women and 24 men with mean ageof 32.8 ± 5.7 years constituted case and control groups,respectively. The means of serum triglyceride, totalcholesterol, HDL-C and LDL-C levels in case and controlgroups were 177.0 ± 118.2 versus 108.7 ± 37.2 mg/dl(P = 0.0001, 186.2 ± 44.1 versus 152.9 ± 3.7 mg/dl(P = 0.0001, 49.9 ± 12.5 versus 46.1 ± 10.7 mg/dl (P = 0.023and 104.8 ± 33.7 versus 84.1 ± 34.0 mg/dl (P = 0.0001,respectively. The prevalence of hypertriglyceridemia andhypercholesterolemia in case and control groups were41.2% versus 18.4 % (P = 0.0001, and 36.3% versus 9.7%(P = 0.0001. According to multivariate analysis, odds ratioswere 3.11 (95% CI: 1.4 -6.6 and 17.4 (95% CI: 2.12-138.3,respectively. Odds ratio for low HDL-C was 0.2 (95% CI:0.08-0.49.Conclusion: Hypertriglyceridemia andhypercholesterolemia were more frequent inmigraineurs. Conversely, low HDL-C was less frequentamong the patients compared with non-migraineurs.

    Full Text Available Abstract Background Worldwide, acute leukemia is the most common type of childhood cancer. It is particularly common in the Hispanic populations residing in the United States, Costa Rica, and Mexico City. The objective of this study was to determine the incidence of acute leukemia in children who were diagnosed and treated in public hospitals in Mexico City. Methods Included in this study were those children, under 15 years of age and residents of Mexico City, who were diagnosed in 2006 and 2007 with leukemia, as determined by using the International Classification of Childhood Cancer. The average annual incidence rates (AAIR, and the standardized average annual incidence rates (SAAIR per million children were calculated. We calculated crude, age- and sex-specific incidence rates and adjusted for age by the direct method with the world population as standard. We determined if there were a correlation between the incidence of acute leukemias in the various boroughs of Mexico City and either the number of agricultural hectares, the average number of persons per household, or the municipal human development index for Mexico (used as a reference of socio-economic level. Results Although a total of 610 new cases of leukemia were registered during 2006-2007, only 228 fit the criteria for inclusion in this study. The overall SAAIR was 57.6 per million children (95% CI, 46.9-68.3; acute lymphoblastic leukemia (ALL was the most frequent type of leukemia, constituting 85.1% of the cases (SAAIR: 49.5 per million, followed by acute myeloblastic leukemia at 12.3% (SAAIR: 6.9 per million, and chronic myeloid leukemia at 1.7% (SAAIR: 0.9 per million. The 1-4 years age group had the highest SAAIR for ALL (77.7 per million. For cases of ALL, 73.2% had precursor B-cell immunophenotype (SAAIR: 35.8 per million and 12.4% had T-cell immunophenotype (SAAIR 6.3 per million. The peak ages for ALL were 2-6 years and 8-10 years. More than half the children (58.8% were

  20. Amiodarone-Induced Pulmonary Toxicity – A Frequently Missed Complication (United States)

    Sweidan, Alexander J.; Singh, Navneet K.; Dang, Natasha; Lam, Vinh; Datta, Jyoti


    INTRODUCTION Amiodarone is often used in the suppression of tachyarrhythmias. One of the more serious adverse effects includes amiodarone pulmonary toxicity (APT). Several pulmonary diseases can manifest including interstitial pneumonitis, organizing pneumonia, acute respiratory distress syndrome, diffuse alveolar hemorrhage, pulmonary nodules or masses, and pleural effusion. Incidence of APT varies from 5–15% and is correlated to dosage, age of the patient, and preexisting lung disease. DESCRIPTION A 56-year-old male with a past medical history of coronary artery disease and chronic obstructive pulmonary disease was admitted for a coronary artery bypass graft. Post-operatively, the patient was admitted to the ICU for ventilator management and continued to receive his home dose of amiodarone 400 mg orally twice daily, which he had been taking for the past 3 months. The patient was found to be hypoxemic with a PaO2 52 mmHg and bilateral infiltrates on chest x-ray. Patient also complained of new onset dyspnea. Physical exam found bilateral rhonchi with bibasilar crackles and subcutaneous emphysema along the left anterior chest wall. Daily chest x-rays showed worsening of bilateral interstitial infiltrates and pleural effusions. A chest high-resolution computed tomography on post-operative day 3 showed extensive and severe bilateral ground glass opacities. APT was suspected and amiodarone was discontinued. A course of oral prednisone without antibiotics was initiated, and after one week of treatment the chest film cleared, the PaO2 value normalized and dyspnea resolved. DISCUSSION APT occurs via cytotoxic T cells and indirectly by immunological reaction. Typically the lungs manifest a diffuse interstitial pneumonitis with varying degrees of fibrosis. Infiltrates with a ‘ground-glass’ appearance appreciated on HRCT are more definitive than chest x-ray. Pulmonary nodules can be seen, frequently in the upper lobes. These are postulated to be accumulations of
