    Patient-centered health care recognizes that adolescents and parents are stakeholders in adolescent health. We investigate adolescent and parent interest in receiving information about health topics and parent-teen communication from clinicians. Ninety-one parent-adolescent dyads in one practice completed individual interviews. Items assessed levels of interest in receiving health and health communication information from the adolescent's doctor about 18 topics, including routine, mental health, sexual health, substance use, and injury prevention issues. Analyses tested differences between parents and adolescents, within-dyad correlations, and associations with adolescent gender and age. Most parents were female (84%). Adolescents were evenly divided by gender; 36 were aged 12-13 years, 35 were aged 14-15 years, and 20 were aged 16-17 years. Adolescent race reflected the practice population (60% black; 35% white). The vast majority of parents and adolescents reported moderate or high levels of interest in receiving information about all 18 health issues and information to increase parent-teen communication about these topics. Parents' interest in receiving information varied by adolescent age when the expected salience of topics varied by age (e.g., acne, driving safety), whereas adolescents reported similar interest regardless of age. Adolescent gender influenced parent and adolescent interest. Level of interest in receiving information from doctors within adolescent-parent pairs was not significantly correlated for one-half of topics. Parents and adolescents want health care professionals to help them learn and talk about a wide range of adolescent health topics. Feasible primary care interventions that effectively improve parent-teen health communication, and specific adolescent health outcomes are needed.

    Medical student exposure to cardiothoracic surgery has been facilitated by many scholarship opportunities. This study reviews the long-term interest of students at our institution who have received such support. After the first or second year of medical school, participants were selected to receive scholarships for clinical or research activities in cardiothoracic surgery ranging from 4 to 8 weeks in duration. These were funded by the American Association for Thoracic Surgery, Society of Thoracic Surgeons, Southern Thoracic Surgical Association, or a private family donor. Over time, each student's scholarship type, current interest in cardiothoracic surgery, and current education or career status was prospectively monitored in an institutional database. Since 1999, 45 students received scholarships. Eight (18%) were funded by the American Association for Thoracic Surgery, two (4%) by The Society of Thoracic Surgeons one (2%) by the Southern Thoracic Surgical Association, and 34 (76%) by private donors. The median follow-up of graduated students is 7 years. Of the 20 (44%) with an active current interest in cardiothoracic surgery, 2 are faculty, 1 is a fellow, 1 is in an integrated 6-year program, 11 are in general surgery residency and are planning to apply to cardiothoracic surgery fellowship, and the remaining 5 are in medical school and planning a cardiothoracic surgery career. Of all former medical students who received cardiothoracic surgery research scholarships and who have now made a career choice, 17.4% chose cardiothoracic surgery. More than one-third of medical students who received scholarships in cardiothoracic surgery maintained their interest over time, and more than half maintained interest in a surgical field. Although long-term data are scarce, it remains critical to foster mentoring relationships with students over time to guide their career choices. Copyright © 2015 The Society of Thoracic Surgeons.

    There is great interest in leveraging technology, including cell phones and computers, to improve healthcare. A range of e-health applications pertaining to mental health such as messaging for prescription refill or mobile device videoconferencing are becoming more available, but little is known about the mental health patient's interest in using these newer applications. We mailed a survey to 300 patients seen in the general mental health clinic of a local Veterans Affairs Medical Center. Survey questions focused on interest in use of cell phones, tablets, and other computers in patients' interactions with the healthcare system. A total of 74 patients, primarily treated for depression, post-traumatic stress disorder, or anxiety disorders, returned completed surveys. Nearly all reported having a cell phone (72/74, 97%), but fewer than half reported having a smartphone (35/74, 47%). Overall, a substantial majority (64/74, 86%) had access to an Internet-capable device (smartphone or computer, including tablets). Respondents appeared to prefer computers to cell phones for some health-related communications, but did not express differential interest for other tasks (such as receiving appointment reminders). Interest in use was higher among younger veterans. Most veterans with a mental health diagnosis have access to technology (including cell phones and computers) and are interested in using that technology for some types of healthcare-related communications. While there is capacity to utilize information technology for healthcare purposes in this population, interests vary widely, and a substantial minority does not have access to relevant devices. Although interest in using computers for health-related communication was higher than interest in using cell phones, single-platform technology-based interventions may nonetheless exclude crucial segments of the population.

    Methadone maintenance therapy (MMT) is crucial for HIV prevention and treatment in people who inject opioids. In Malaysia, a large proportion of the prison population is affected by both HIV and opioid use disorders. This study assessed individual preferences and factors associated with interest in receiving MMT among male prisoners meeting criteria for opioid dependence in Malaysia. A convenience sample of 96 HIV-positive and 104 HIV-negative incarcerated men who met pre-incarceration criteria for opioid dependence was interviewed using a structured questionnaire to examine participant characteristics and attitudes toward MMT. Factors associated with interest in prison-based MMT initiation were identified using logistic regression analysis. Among all participants, 85 (42.5%) were interested in receiving MMT within prison. Independent correlates of interest in prison-based MMT were being previously married (AOR=4.15, 95% CI: 1.15, 15.02), previously incarcerated (AOR=5.68, 95% CI: 1.54, 21.02), depression (AOR=3.66, 95% CI: 1.68, 7.98), daily heroin use in the 30days prior to incarceration (AOR=5.53, 95% CI: 1.65, 18.58), and more favorable attitudes toward MMT (AOR=19.82, 95% CI: 6.07, 64.74). Overall, interest in receiving prison-based MMT was low, and was associated with adverse social, mental health, and drug use consequences. Incarceration provides a unique opportunity to initiate MMT for those who need it, however, optimal scale-up efforts must be systemic and address modifiable factors like improving attitudes toward and motivation for MMT. Informed or shared decision-making tools may be useful in improving expectations and acceptability of MMT. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Mobile health (mHealth) refers to the use of mobile technology (e.g., smartphones) and software (i.e., applications) to facilitate or enhance health care. Several mHealth programs act as either stand-alone aids for Veterans with post-traumatic stress disorder (PTSD) or adjuncts to conventional psychotherapy approaches. Veterans enrolled in a Veterans Affairs outpatient treatment program for PTSD (N = 188) completed anonymous questionnaires that assessed Veterans' access to mHealth-capable devices and their utilization of and interest in mHealth programs for PTSD. The majority of respondents (n = 142, 76%) reported having access to a cell phone or tablet capable of running applications, but only a small group (n = 18) reported use of existing mHealth programs for PTSD. Age significantly predicted ownership of mHealth devices, but not utilization or interest in mHealth applications among device owners. Around 56% to 76% of respondents with access indicated that they were interested in trying mHealth programs for such issues as anger management, sleep hygiene, and management of anxiety symptoms. Findings from this sample suggest that Veterans have adequate access to, and interest in, using mHealth applications to warrant continued development and evaluation of mobile applications for the treatment of PTSD and other mental health conditions.

This study demonstrates the impact results of this choice for the company and for the shareholders. The company will have a fiscal tax advantage with the use of JSCP, as the tax base for income and social contribution is reduced after the deduction of interest on capital as a financial expense.

  11. Rapid stress system drives chemical transfer of fear from sender to receiver.

    Directory of Open Access Journals (Sweden)

    Jasper H B de Groot

    Full Text Available Humans can register another person's fear not only with their eyes and ears, but also with their nose. Previous research has demonstrated that exposure to body odors from fearful individuals elicited implicit fear in others. The odor of fearful individuals appears to have a distinctive signature that can be produced relatively rapidly, driven by a physiological mechanism that has remained unexplored in earlier research. The apocrine sweat glands in the armpit that are responsible for chemosignal production contain receptors for adrenalin. We therefore expected that the release of adrenalin through activation of the rapid stress response system (i.e., the sympathetic-adrenal medullary system is what drives the release of fear sweat, as opposed to activation of the slower stress response system (i.e., hypothalamus-pituitary-adrenal axis. To test this assumption, sweat was sampled while eight participants prepared for a speech. Participants had higher heart rates and produced more armpit sweat in the fast stress condition, compared to baseline and the slow stress condition. Importantly, exposure to sweat from participants in the fast stress condition induced in receivers (N = 31 a simulacrum of the state of the sender, evidenced by the emergence of a fearful facial expression (facial electromyography and vigilant behavior (i.e., faster classification of emotional facial expressions.

    2005-03-01

    The overall purpose of this preliminary study to a clinical trial is to explore the feasibility of recruiting men receiving androgen ablation therapy (AAT) for locally advanced prostate cancer to a future strength training study for the prevention of osteoporosis. The threefold specific purpose of this comparative and correlational study is to (a) describe the prevalence of risk factors for osteoporosis, (b) compare functional status and symptom distress between those interested and not interested in a future strength training study, and (c) examine relationships among self-efficacy for strength training, functional status, symptom distress, years since cancer diagnosis, and cumulative dose of AAT in this at-risk population. Data were obtained from 40 Caucasian men (mean age = 75.8 years) with locally advanced prostate cancer, capable of self-care, and receiving AAT. The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaires (QLQ) EORTC QLQ-C30 and EORTC QLQ-PR25 (prostate cancer specific) were used to measure functional status and symptom distress. A 6-item, investigator-developed questionnaire was used to measure self-efficacy for learning and overcoming barriers to strength training. The majority of these men had multiple risk factors for osteoporosis, in addition to receiving AAT, and had not completed bone mineral density (BMD) testing. A high percentage (67.5%) expressed interest in a future strength training protocol for osteoporosis prevention; functional status and symptom distress did not appear to influence this interest. Several aspects of functional status and symptom distress were significantly related to self-efficacy for learning and overcoming barriers to strength training. Years since cancer diagnosis and cumulative dose of AAT were not significantly related to self-efficacy for strength training, but age was related. This study informs a planned future experimental study by establishing the recruitment

  13. Do Patients with Advanced Cancer and Unmet Palliative Care Needs Have an Interest in Receiving Palliative Care Services?

    Abstract Background: It is not known whether unmet palliative care needs are associated with an interest in palliative care services among patients with advanced cancer receiving ongoing oncology care. Objective: To assess the association between unmet palliative care needs and patient interest in subspecialty palliative care services. Design: Cross-sectional telephone survey. Subjects and setting: One hundred sixty-nine patients with advanced cancer receiving care from 20 oncologists at two academic cancer centers. Measurements: Surveys assessed palliative care needs in six domains. Patients were read a description of palliative care and then asked three questions about their current interest in subspecialty palliative care services (perceived need, likelihood of requesting, willingness to see if their oncologist recommended; all outcomes on 0–10 Likert scale). Results: The vast majority of patients described unmet palliative care needs, most commonly related to psychological/emotional distress (62%) and symptoms (62%). In fully adjusted models accounting for clustering by oncologist, unmet needs in these domains were associated with a higher perceived need for subspecialty palliative care services (psychological/emotional needs odds ratio [OR] 1.30; 95% confidence interval [CI] 1.06–1.58; p=0.01; symptom needs OR 1.27; 95% CI 1.01–1.60; p=0.04). There was no significant association between unmet needs and likelihood of requesting palliative care services. Willingness to see palliative care if oncologist recommended was high (mean 8.6/10, standard deviation [SD] 2). Conclusion: Patients with advanced cancer and unmet symptom and psychological/emotional needs perceive a high need for subspecialty palliative care services but may not request them. Efforts to increase appropriate use of subspecialty palliative care for cancer may require oncologist-initiated referrals. PMID:24673544

    The implementation of rapid HIV testing in Brazil began in 2006 for specific groups, and from 2009 was extended to the Counseling and Testing Centers (CTC) in certain Brazilian capitals. The aim of this study was to compare two groups of individuals: those diagnosed with HIV infection by conventional testing and those diagnosed with rapid testing, with respect to: the waiting time before receiving medical care, the time of the first laboratory tests and the virological, immune and clinical status. This is a cross-sectional study to compare a group with individuals diagnosed by conventional testing (2006-2008) and another with those diagnosed by rapid testing (2010-2011).The median time between blood collection and diagnosis of HIV in the conventional test group was 76 days, while in the rapid test group 94.2% of the subjects received their results on the same day of blood collection (p test group, the median period of time before the first consultation with an infectious disease specialist was 99 days, and for the rapid test group the time was 14 days (p test group (p test group (472) was higher than in the conventional test group (397) (p = 0.01). The introduction of rapid HIV testing as a diagnostic strategy has reduced the waiting times for medical care and laboratory tests and also allowed earlier diagnosis of HIV infection than with the conventional test.

    Despite the strong correlation between HIV and corrections, testing and prevention efforts have largely been ignored among community corrections populations. The current study is a secondary analysis to compare characteristics of individuals under community corrections supervision who completed rapid HIV testing with those who refused such testing (N = 2,382) in Baltimore, Maryland, and Providence, Rhode Island. Results indicate that the following variables were significantly associated with the receipt of rapid HIV testing: being female (p = .024), Black race (p = .004), homeless (p = .016), early age of crime onset (p = .001), more drug use during the past 90 days (p = .033), and previously tested for hepatitis C virus/hepatitis B virus (p = .024). Such findings make it especially important that individuals under community supervision be linked with services in the community to ensure that HIV testing and health care planning occur simultaneously. © The Author(s) 2016.

    For successful long-term asthma care, self-management education is a cornerstone. Little is known about associations between patients' interest in education, asthma control and care delivery. We compared patients' characteristics, asthma control and patients' perspective about asthma care in subjects with and without interest in asthma education. Moreover, we assessed reasons, why patients denied participating in asthma education. Baseline data of 223 patients with asthma (age 43 ± 12 years, 38% male, 58% non-smokers, 13% current smokers), who participated in a multicentre longitudinal controlled study, are reported. At baseline, patients completed the Asthma Control Test (ACT), the Patient Assessment Chronic Illness Care questionnaire (PACIC 5A) and stated their interest in an asthma education programme. Overall, 34% of all participants showed uncontrolled asthma. One hundred and twenty-five (56%) patients were interested in education. Compared to patients without interest, they were characterised by male gender (p = 0.013), worse asthma control (p < 0.001), and perception of lower quality of chronic asthma care delivery, in particular lower self-management support (p < 0.001). Main reasons for rejecting asthma education were having sufficient asthma knowledge, having only mild asthma, receiving adequate medical support and lack of time. More than half of the patients were interested in asthma education. Interest was associated with worse asthma control and lower receipt of care according to the Chronic Care Model. Considering these aspects, this approach may help to improve care quality and allow targeting interventions to those patients who are interested in becoming active participants in their care and who might benefit most.

    Research indicates up to one-third of rapid response team calls relate to end-of-life symptoms. The CriSTAL criteria were developed as a screening tool to identify high risk of death within three months. The primary purpose of this pilot study was to investigate the timing of palliative care referrals in patients receiving rapid response team services, and patients' CriSTAL criteria score on admission. The potential feasibility of using the CriSTAL tool to stimulate earlier Palliative Care Team (PCT) referral served as an underlying goal, and investigation of a relationship between specific CriSTAL criteria and the prediction of in-hospital death was a secondary objective. A retrospective chart review of rapid response calls made in 2015 was used to identify patient risk of death on admission based on the CriSTAL criteria. The presence and timing of PCT referral as well as patient survival status to hospital discharge were documented for comparison. A sample of 183 charts from 584 inpatients involved in over 600 RRT events recorded in 2015. The study was undertaken in a 676-bed teaching hospital in the Midwestern U.S. Ninety-one patients died during the hospital stay while 92 patients from the 493 individuals who survived were randomly selected for full analysis. Applying CriSTAL criteria to the 141 individuals aged 50 years or older indicated that frailty (OR=1.43, 95%CI 1.08-1.89, p=0.012), being a male (OR=3.14; 95%CI 1.40-7.05, p=0.006), and the presence of two or more comorbidities (OR=3.71, 95%CI 1.67-8.24, p=0.001) were the most significant predictors of in-hospital death after adjusting for age. A CriSTAL score of 6 was the optimal cut-off for high-risk of in-hospital death. Palliative care consultations within the high-risk population occurred for 45.2% of the deceased and 40.4% of the survivors. Consultation often occurred within two days of the RRT event and many patients (46.8%) died within one day of the consultation. A positive relationship was found

    This paper examines the awareness and use of nonoccupational HIV post-exposure prophylaxis (nPEP) in Spain, and the factors that influence this awareness. Between June 2009 and July 2010, a mobile unit offered free, rapid HIV tests in a number of Spanish cities. A total of 2545 people were passively recruited and tested, and answered a self-administered questionnaire containing sociodemographic, behavioural and nPEP-related questions. Bivariate and multivariate analyses were performed, stratifying by gender/sexual behaviour. Some 34% of the responders were men who have sex with men (MSM), 30% were men who have sex exclusively with women (MSW), and 35% were women. Approximately 26% were foreigners, 46% had a university degree, and 51% had previously taken an HIV test. Overall, 22% were aware of nPEP. Only 2% had ever used it; 70% of these after high-risk sexual intercourse. Awareness was higher among MSM (34%) than women (16%) and MSW (15%). Multivariate analysis showed a lack of nPEP awareness to be associated with being born in Latin America, while awareness increased with the number of previous HIV tests among women and MSW. In MSM, awareness was also associated with having a university degree, the degree of interaction with gay culture, number of partners, and use of the internet as the main way of meeting partners. nPEP awareness in the studied population was unacceptably low. The promotion of its availability should be made a major objective of prevention programmes, as a complementary measure to condom use. © 2012 British HIV Association.

  3. Optimizing end-to-end system performance for millimeter and submillimeter spectroscopy of protostars : wideband heterodyne receivers and sideband-deconvolution techniques for rapid molecular-line surveys

    Science.gov (United States)

    Sumner, Matthew Casey

    This thesis describes the construction, integration, and use of a new 230-GHz ultra-wideband heterodyne receiver, as well as the development and testing of a new sideband-deconvolution algorithm, both designed to enable rapid, sensitive molecular-line surveys. The 230-GHz receiver, known as Z-Rex, is the first of a new generation of wideband receivers to be installed at the Caltech Submillimeter Observatory (CSO). Intended as a proof-of-concept device, it boasts an ultra-wide IF output range of sim 6 - 18 GHz, offering as much as a twelvefold increase in the spectral coverage that can be achieved with a single LO setting. A similarly wideband IF system has been designed to couple this receiver to an array of WASP2 spectrometers, allowing the full bandwidth of the receiver to be observed at low resolution, ideal for extra-galactic redshift surveys. A separate IF system feeds a high-resolution 4-GHz AOS array frequently used for performing unbiased line surveys of galactic objects, particularly star-forming regions. The design and construction of the wideband IF system are presented, as is the work done to integrate the receiver and the high-resolution spectrometers into a working system. The receiver is currently installed at the CSO where it is available for astronomers' use. In addition to demonstrating wideband design principles, the receiver also serves as a testbed for a synthesizer-driven, active LO chain that is under consideration for future receiver designs. Several lessons have been learned, including the importance of driving the final amplifier of the LO chain into saturation and the absolute necessity of including a high-Q filter to remove spurious signals from the synthesizer output. The on-telescope performance of the synthesizer-driven LO chain is compared to that of the Gunn-oscillator units currently in use at the CSO. Although the frequency agility of the synthesized LO chain gives it a significant advantage for unbiased line surveys, the cleaner

  4. Communication and common interest.

    Directory of Open Access Journals (Sweden)

    Peter Godfrey-Smith

    Full Text Available Explaining the maintenance of communicative behavior in the face of incentives to deceive, conceal information, or exaggerate is an important problem in behavioral biology. When the interests of agents diverge, some form of signal cost is often seen as essential to maintaining honesty. Here, novel computational methods are used to investigate the role of common interest between the sender and receiver of messages in maintaining cost-free informative signaling in a signaling game. Two measures of common interest are defined. These quantify the divergence between sender and receiver in their preference orderings over acts the receiver might perform in each state of the world. Sampling from a large space of signaling games finds that informative signaling is possible at equilibrium with zero common interest in both senses. Games of this kind are rare, however, and the proportion of games that include at least one equilibrium in which informative signals are used increases monotonically with common interest. Common interest as a predictor of informative signaling also interacts with the extent to which agents' preferences vary with the state of the world. Our findings provide a quantitative description of the relation between common interest and informative signaling, employing exact measures of common interest, information use, and contingency of payoff under environmental variation that may be applied to a wide range of models and empirical systems.

    To develop a matrix model for the prediction of rapid radiographic progression (RRP) in subpopulations of patients with recent-onset rheumatoid arthritis (RA) receiving different dynamic treatment strategies. Data from 465 patients with recent-onset RA randomised to receive initial monotherapy or combination therapy were used. Predictors for RRP (increase in Sharp-van der Heijde score > or =5 after 1 year) were identified by multivariate logistic regression analysis. For subpopulations, the estimated risk of RRP per treatment group and the number needed to treat (NNT) were visualised in a matrix. The presence of autoantibodies, baseline C-reactive protein (CRP) level, erosion score and treatment group were significant independent predictors of RRP in the matrix. Combination therapy was associated with a markedly reduced risk of RRP. The positive and negative predictive values of the matrix were 62% and 91%, respectively. The NNT with initial combination therapy to prevent one patient from RRP with monotherapy was in the range 2-3, 3-7 and 7-25 for patients with a high, intermediate and low predicted risk, respectively. The matrix model visualises the risk of RRP for subpopulations of patients with recent-onset RA if treated dynamically with initial monotherapy or combination therapy. Rheumatologists might use the matrix for weighing their initial treatment choice.

    Full Text Available In recent years, there has been increased global awareness of Islamic finance. This topic is mainly opened with respect to the great financial crisis that mostly hit the banking system and the financial markets and caused many bank bankruptcies and state interventions. This paper analyzes the basic principles of Islamic banking. The absolute prohibition of receiving and giving interest (Riba and profit-and-loss sharing (PLS paradigms are elaborated in detail; they are primarily based on mudarabah (profit-sharing and musyarakah (joint venture concepts which nowadays are becoming an accepted way of doing business in several Western multinational banks. An overall comparison of the advantages of Islamic vs. conventional banking is also given. Islamic finance technology solutions have matured and they will face various challenges in the following decades, due to conventional banks offering, increasingly, Islamic products. The need for a more comprehensive environment and regulatory framework is emphasized, so that Islamic banking development can be ensured.

    2014-01-01

    Multiple-input multiple-output (MIMO) systems can increase the spectral efficiency in wireless communications. However, the interference becomes the major drawback that leads to high computational complexity at both transmitter and receiver. In particular, the complexity of MIMO receivers can be prohibitively high. As an efficient mathematical tool to devise low complexity approaches that mitigate the interference in MIMO systems, lattice reduction (LR) has been widely studied and employed over the last decade. The co-authors of this book are world's leading experts on MIMO receivers, and here they share the key findings of their research over years. They detail a range of key techniques for receiver design as multiple transmitted and received signals are available. The authors first introduce the principle of signal detection and the LR in mathematical aspects. They then move on to discuss the use of LR in low complexity MIMO receiver design with respect to different aspects, including uncoded MIMO detection...

    An improved long-life design for solar energy receivers provides for greatly reduced thermally induced stress and permits the utilization of less expensive heat exchanger materials while maintaining receiver efficiencies in excess of 85% without undue expenditure of energy to circulate the working fluid. In one embodiment, the flow index for the receiver is first set as close as practical to a value such that the Graetz number yields the optimal heat transfer coefficient per unit of pumping energy, in this case, 6. The convective index for the receiver is then set as closely as practical to two times the flow index so as to obtain optimal efficiency per unit mass of material.

  18. Receiver Gain Modulation Circuit

    Science.gov (United States)

    Jones, Hollis; Racette, Paul; Walker, David; Gu, Dazhen

    2011-01-01

    A receiver gain modulation circuit (RGMC) was developed that modulates the power gain of the output of a radiometer receiver with a test signal. As the radiometer receiver switches between calibration noise references, the test signal is mixed with the calibrated noise and thus produces an ensemble set of measurements from which ensemble statistical analysis can be used to extract statistical information about the test signal. The RGMC is an enabling technology of the ensemble detector. As a key component for achieving ensemble detection and analysis, the RGMC has broad aeronautical and space applications. The RGMC can be used to test and develop new calibration algorithms, for example, to detect gain anomalies, and/or correct for slow drifts that affect climate-quality measurements over an accelerated time scale. A generalized approach to analyzing radiometer system designs yields a mathematical treatment of noise reference measurements in calibration algorithms. By treating the measurements from the different noise references as ensemble samples of the receiver state, i.e. receiver gain, a quantitative description of the non-stationary properties of the underlying receiver fluctuations can be derived. Excellent agreement has been obtained between model calculations and radiometric measurements. The mathematical formulation is equivalent to modulating the gain of a stable receiver with an externally generated signal and is the basis for ensemble detection and analysis (EDA). The concept of generating ensemble data sets using an ensemble detector is similar to the ensemble data sets generated as part of ensemble empirical mode decomposition (EEMD) with exception of a key distinguishing factor. EEMD adds noise to the signal under study whereas EDA mixes the signal with calibrated noise. It is mixing with calibrated noise that permits the measurement of temporal-functional variability of uncertainty in the underlying process. The RGMC permits the evaluation of EDA by

  20. Diversity of MMSE MIMO Receivers

    CERN Document Server

    Mehana, Ahmed Hesham

    2011-01-01

    In most MIMO systems, the family of waterfall error curves, calculated at different spectral efficiencies, are asymptotically parallel at high SNR. In other words, most MIMO systems exhibit a single diversity value for all {\\em fixed} rates. The MIMO MMSE receiver does not follow this pattern and exhibits a varying diversity in its family of error curves. This effect cannot be captured by DMT analysis, due to the fact that all fixed rates correspond to the same multiplexing gain, thus they cannot be differentiated within DMT analysis. This work analyzes this interesting behavior of the MMSE MIMO receiver and produces the MMSE MIMO diversity at each rate. The diversity of the quasi-static flat-fading MIMO channel consisting of any arbitrary number of transmit and receive antennas is fully characterized, showing that full spatial diversity is possible for all antenna configurations if and only if the rate is within a certain bound which is a function of the number of antennas. For other rate brackets, the avail...

  2. Mitigation Technique for Receiver Performance Variation of Multi-Color Channels in Visible Light Communication

    Directory of Open Access Journals (Sweden)

    Yeong Min Jang

    2011-06-01

    Full Text Available “Green” and energy-efficient wireless communication schemes have recently experienced rapid development and garnered much interest. One such scheme is visible light communication (VLC which is being touted as one of the next generation wireless communication systems. VLC allows communication using multi-color channels that provide high data rates and illumination simultaneously. Even though VLC has many advantageous features compared with RF technologies, including visibility, ubiquitousness, high speed, high security, harmlessness for the human body and freedom of RF interference, it suffers from some problems on the receiver side, one of them being photo sensitivity dissimilarity of the receiver. The photo sensitivity characteristics of a VLC receiver such as Si photo-detector depend on the wavelength variation. The performance of the VLC receiver is not uniform towards all channel colors, but it is desirable for receivers to have the same performance on each color channel. In this paper, we propose a mitigation technique for reducing the performance variation of the receiver on multi-color channels. We show received power, SNR, BER, output current, and outage probability in our simulation for different color channels. Simulation results show that, the proposed scheme can reduce the performance variation of the VLC receiver on multi-color channels.

    This book demonstrates how to design a wideband receiver operating in current mode, in which the noise and non-linearity are reduced, implemented in a low cost single chip, using standard CMOS technology.  The authors present a solution to remove the transimpedance amplifier (TIA) block and connect directly the mixer’s output to a passive second-order continuous-time Σ∆ analog to digital converter (ADC), which operates in current-mode. These techniques enable the reduction of area, power consumption, and cost in modern CMOS receivers.

  4. Biconical receiving antenna

    Grimes, Dale M.

    1982-05-01

    The modal solution to a biconical receiving antenna with arbitrary arm angles and lengths is presented in the form of sums over special functions; sums which are exact in the sense that no electromagnetic approximations are made. The antenna load is confined within a sphere of small radius centered at the apices of the cones. The analytical formulation is presented, along with solutions for ψ very small and very large, and certain selected numerical data. The general solution permits calculation of all detailed fields near and far, both receiving and transmitting current modes on the antenna arms and caps and the power and the momentum absorbed by the antenna from an incoming plane wave. It is shown that the receiving current modes are necessary for electromagnetic momentum to be conserved during power reception. Detailed calculation of comparative receiving and transmitting admittances confirms that they are identical, as predicted by the reciprocity theorem. The radiation patterns, however, for retransmission during reception and for transmission differ.

  6. Rangifer and human interests

    Directory of Open Access Journals (Sweden)

    David G. Anderson

    2000-03-01

    Full Text Available This article reviews biological and anthropological literatute on wild and tame Rangifer to demonstrate the powerful effect that this species has had on the imaginations of biologists, social scientists and local hunters. Through identifying a general 'human interest' in Rangifer, the author argues that there is great potential for these three communities to work together. To demonstrate this idea, the paper reviews several examples of successful and unsuccessful 'alliances' between local peoples and both natural and social scientists which have had a fundamental impact upon the history of these sciences. The paper examines recent theorerical models which suggest that human action is a major factor in the behaviour and ecology of the animals. The paper also analyses the ideas of many indigenous people for whom there is no categorical difference between semi-domesticated, semi-sedentary and migratory Rangifer through comparison with many 'anomalous' texts in English and Russian language wildlife biology. By reviewing the history of scholarly interest in Rangifer, the author argues that contemporary models of Rangifer behaviour and identity could be 'revitalised' and 'recalibrated' through the establishment of that dialogue between scientists and local peoples which so characterised the 19th century. Such a dialogue, it is argued, would help mediate many of the political conflicts now appearing in those districts where Rangifer migrate.

    For a few years now, there has been a high interest in monitoring the global ship traffic from space. A few satellite, capable of listening for ship borne AIS transponders have already been launched, and soon the AAUSAT3, carrying two different types of AIS receivers will also be launched. One...... of the AIS receivers onboard AAUSAT3 is an SDR based AIS receiver. This paper serves to describe the background of the AIS system, and how the SDR based receiver has been integrated into the AAUSAT3 satellite. Amongst some of the benefits of using an SDR based receiver is, that due to its versatility, new...... detection algorithms are easily deployed, and it is easily adapted the new proposed AIS transmission channels....

  8. Globalization, values, interests

    2003-01-01

    Full Text Available The nature of the international politics, after the Cold War directed by the U.S. as the only current super-power, are considered in the text. The author’s intention is to stress the main points of divergence between moralistic-valuable rhetoric and the foreign policy practice of the U.S. In that sense, the examples of the American stand, i.e. the active treatment of the Yugoslav crisis, on the one hand, and the crisis in the Persian Gulf, on the other hand, is considered. The author’s conclusion is that the foreign policy of the only current super-power is still directed by interests rather then by values. In the concluding part, the author presents an anthropologic argument in favor of reestablishing "balance of power" as the only guarantee for peace and stability of the world.

    waves behave in the air spaces leading to the interior surfaces of eardrums. A linear mathematical model with well-defined inputs is used for exploring how the directionality varies with the binaural directional cues and the amplitude and phase gain of the sound pathway to the inner surface...... of such pressure difference receiving ears have been hampered by lack of suitable experimental methods. In this review, we review the methods for collecting reliable data on the binaural directional cues at the eardrums, on how the eardrum vibrations depend on the direction of sound incidence, and on how sound...

    Full Text Available Abstract A large number of randomized clinical trials with important health outcomes are completed each year. Those with favorable findings are typically reported and published rapidly, while the publication of those with unfavorable results is often delayed or given a positive "spin." This observation applies primarily to industry-sponsored trials. Our objectives are to discuss the responsibility of pharmaceutical firms to the public with respect to timely, complete, and unbiased information from all randomized clinical trials and to propose solutions for improvements. We believe that in addition to financial obligations to their shareholders, pharmaceutical companies have social responsibilities to the public and to health care providers. However, private markets do not reward or compel optimal disclosure of drug safety or inferiority information on a voluntary basis. A problem which has not previously been identified relates to non-comparability of drugs. A case report from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT illustrates how public interests may be violated due to failure to inform about drug inferiority. The current system for dissemination of relevant medical information could be improved if all involved parties collaborated fully. However, full disclosure of trial results is unlikely when research results are unfavorable to the firm. We conclude that expanded government regulations will be required for a satisfactory solution to the problem.

  12. ICPD: in whose interest?

    Science.gov (United States)

    Shiva, M

    1994-06-01

    The International Conference on Population and Development (ICPD) is set for September 1994. Arms control and control of military interests are as crucial as population control. The expenditure on the military and arms should go to social measures and true socioeconomic development. Women are leading the movement against war and towards peace. Women make up 70% of current refugees of ethnic conflicts. The conquest of free trade with little or no restriction and globalization trends forces developing countries to accept nonessential luxury items which tend to be irrational, hazardous consumer articles and technologies from industrialized countries. The privileged elite in developing countries and the industrialized countries overconsume, while the basic needs of the poor majority are not being met. The rich view the poor as a global threat and a threat for environmental degradation. They believe that free trade will solve all problems, yet it only marginalizes the poor and the vulnerable. The pattern of overconsumption is the threat. The poor are characterized as demons responsible for the population explosion. Women are angry that population control policies are attempts to control women's fertility. Specifically, most contraceptive technologies and most family planning programs target women. Male responsibility is ignored. Religious fundamentalists tell women not to become pregnant, not to use contraception, and not to seek abortion, yet they allow male sex behavior, e.g., sexual violence. This attitude leaves women vulnerable to unwanted pregnancies, sexually transmitted diseases, and AIDS. Developing countries should be concerned about chapter III on Population, Environment, and Development in the ICPD text. Most countries, including India, have formed a consensus on this chapter. The Vatican and some Latin American countries have objections, however. The meeting in Cairo will likely continue to promote the view that the fertility of women in developing

    Objectives: A gluten-free diet is the treatment for celiac disease, but pharmaceutical agents are being developed. The level of interest amongst patients in using a medication to treat celiac disease is unknown. This study examined the level of interest amongst patients in medication to treat celiac disease. Methods: A questionnaire was distributed to celiac disease patients and data were collected on demographics, presentation, and interest in medication. Three validated celiac disease-specific instruments were incorporated: Celiac Disease Associated Quality of Life, the Celiac Symptom Index, and the Celiac Dietary Adherence Test. Results: Responses were received from 365 individuals with biopsy-proven celiac disease. Respondents were 78% (n = 276) female, 48% (n = 170) over 50 years of age, and experienced a classical (diarrhea predominant) presentation in 44% (n = 154). Of the 339 individuals answering the question regarding use of a medication to treat celiac disease, 66% were interested. Interest was greatest in older individuals (71% >50 years of age versus 60% celiac disease are interested in using a medication. Interest was highest among men, older individuals, frequent restaurant customers, individuals dissatisfied with their weight or concerned with the cost of a gluten-free diet, and those with a worse quality of life.

  7. EDITORIAL: Interesting times

    Dobson Honorary Editor, Ken

    1996-01-01

    `May you live in interesting times' - old Chinese curse. First, many thanks to John Avison, the retiring Honorary Editor, for his hard work over the last five years, and the steady development in style and content under his stewardship. I can only hope to live up to the standards that he set. The next five years will take us into a new millenium, an event preceded - in England and Wales at least - by a period of stability, reflection and consolidation in education. Or so we are told - but whether such a self-denying ordinance will actually be maintained by the Government both before and after an election in 1997 remains to be seen. Nevertheless, we shall be thankful for any mercies, however small, that permit forward thinking rather than instant response. One of the things that readers of a journal called Physics Education should be thinking about is the continued decline in the numbers of students studying physics post-16. This is not a purely local phenomenon; most European countries are finding a similar decline. There are exceptions, of course: in Scotland numbers studying physics for Highers are increasing. Is such a decline a good thing or a bad thing? Only a minority of post-16 physics students go on to use the bulk of what they have learned in further studies or vocations. Does a knowledge and understanding of physics contribute to the mental well-being and cultural level - let alone material comfort - of any except those who use physics professionally? Is physics defensible as a contribution to the mental armoury of the educated citizen - compared with chemistry, biology - or Latin, say? Or should one rephrase that last question as `Is physics as we teach it today defensible...?' Such questions, and many others no doubt, may well be in the mind of the new Curriculum Officer appointed by the Institute of Physics `to engage in a wide-ranging consultation throughout the entire physics community on the nature and style of post-16 physics programmes, with a

  8. Anchorage Receives Record Snowfall

    Science.gov (United States)

    2002-01-01

    The forecast called for flurries, but the snow accumulated on the ground in Anchorage, Alaska, at the rate of 2 inches per hour (5 cm per hour) for much of Saturday, March 16, 2002. By the time the winter storm passed on Sunday afternoon, Anchorage had received 28.6 inches (72.6 cm) of snow, surpassing by far the previous record of 15.6 inches (39.6 cm) set on December 29, 1955. Flights were canceled and schools were closed as a result of the storm. This true-color image of Alaska was acquired by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), flying aboard the OrbView-2 satellite, on March 18. It appears another large, low-pressure system is heading toward the Anchorage region, which could bring substantially more snowfall. The low-pressure system can be identified by the characteristic spiral pattern of clouds located off Alaska's southwestern coast in this scene.

  12. Conflict of interests, vested interests and health research.

    Science.gov (United States)

    Little, M

    2000-11-01

    This paper examines conflict of interest as it may arise in the activities of research advisory committees and ethical review committees. It distinguishes between vested interests and true conflict of interest. It also examines the ways in which stakeholdings differ from vested interests and conflicting interests differ from conflicts of interest. It explores the overlapping terrain of corruption and conflict of interest. The paper further examines the ways in which scientists, communities and the subjects of medical research all have legitimate stakeholdings in medical research. Each group thus has differently vested interests in the outcomes of the research. The vested interests of medical scientists are particularly complex because scientists have moral commitments to the welfare of patients that may compete with professional and personal interests in the outcome of research performed on those patients as research subjects. The more these interests diverge, the more opportunity will arise for conflict of interest. These observations have implications for the constitution of research advisory and ethical review committees, and the ways in which their discussions are conducted. Some practical help with protocols of discussion can be gained from philosophical and management writings.

  14. Building and Testing a Portable VLF Receiver

    Science.gov (United States)

    McLaughlin, Robert; Krause, L.

    2014-01-01

    Unwanted emissions or signal noise is a major problem for VLF radio receivers. These can occur from man made sources such as power line hum, which can be prevalent for many harmonics after the fundamental 50 or 60 Hz AC source or from VLF radio transmissions such as LORAN, used for navigation and communications. Natural emissions can also be detrimental to the quality of recordings as some of the more interesting natural emissions such as whistlers or auroral chorus may be drowned out by the more common sferic emissions. VLF receivers must selectively filter out unwanted emissions and amplify the filtered signal to a record-able level without degrading the quality.

  15. Four models of family interests.

    Science.gov (United States)

    Groll, Daniel

    2014-10-01

    In this article, I distinguish between 4 models for thinking about how to balance the interests of parents, families, and a sick child: (1) the oxygen mask model; (2) the wide interests model; (3) the family interests model; and (4) the direct model. The oxygen mask model - which takes its name from flight attendants' directives to parents to put on their own oxygen mask before putting on their child's - says that parents should consider their own interests only insofar as doing so is, ultimately, good for the sick child. The wide interests model suggests that in doing well by my child I am at the very same time doing well by myself. My interests can, and plausibly do, encompass the interests of others; they are, to that extent, wide. There is, then, no sharp separation between the interests of the sick child and the interests of other family members. In the family interests model, families themselves are seen as having interests that are neither identical to the sum, nor a simple function, of the interests of individual family members. The family has goals, values, and aspirations that are essentially corporate rather than individual. According to this model, these family interests can explain why sacrifices can sometimes be demanded of some family members for the sake of others in a medical setting. Finally, the direct model takes a simpler view of family members' interests; it claims that these interests matter simply on their own and should be taken into account in making treatment decisions for a sick child. This model openly considers the competing interests that parents and other family members often have when caring for a sick child, and advocates for weighing those interests when making decisions for and about the sick child. While there is room for all four models at the bedside, I argue that the direct model should be highlighted in clinical decision-making. Copyright © 2014 by the American Academy of Pediatrics.

  16. What is interesting? Exploring the appraisal structure of interest.

    Science.gov (United States)

    Silvia, Paul J

    2005-03-01

    Relative to other emotions, interest is poorly understood. On the basis of theories of appraisal process and structure, it was predicted that interest consists of appraisals of novelty (factors related to unfamiliarity and complexity) and appraisals of coping potential (the ability to understand the new, complex thing). Four experiments, using in vivo rather than retrospective methods, supported this appraisal structure. The findings were general across measured and manipulated appraisals, interesting stimuli (random polygons, visual art, poetry), and measures of interest (self-reports, forced-choice, behavioral measures). Furthermore, the appraisal structure was specific to interest (it did not predict enjoyment, a related positive emotion), and appraisals predicted interest beyond relevant traits (curiosity, openness). The appraisal perspective offers a powerful way of construing the causes of interest. Copyright 2005 APA, all rights reserved.

    1998-10-01

    Ever-growing global competition forces manufacturers to deliver more competitive products with better quality, lower price and in short time. One of the most important and challenging tasks faced by value-added product manufacturing industry is substantial reduction of product development time. Rapid prototyping technologies have received significant interests from both research and industrial communities. Due to the model accuracy, integrity and strength problems, their applications are limited. The most common sources of errors in the rapid prototyping and manufacturing systems including Cubital machines can be categorized as mathematical, process-related or material- related errors. In this paper, we present an analysis of accuracy of a Cubital Solider 4600 machine and an application on pattern and mould design and manufacturing. The experimental study determines the relationships between the machine accuracy and dimensions and parameter setting, which can be used to control the accuracy of parts to be built.

    2014-07-01

    Full Text Available Rapid prototyping has received considerable interest with the introduction of affordable rapid prototyping machines. These machines can be used to manufacture physical models from three-dimensional digital mesh models. In this paper, we compare the results obtained with a new, affordable, rapid prototyping machine, and a traditional professional machine. Two separate data sets are used for this, both of which were acquired using terrestrial laser scanning. Both of the machines were able to produce complex and highly detailed geometries in plastic material from models based on terrestrial laser scanning. The dimensional accuracies and detail levels of the machines were comparable, and the physical artifacts caused by the fused deposition modeling (FDM technique used in the rapid prototyping machines could be found in both models. The accuracy of terrestrial laser scanning exceeded the requirements for manufacturing physical models of large statues and building segments at a 1:40 scale.

  5. Cryonics in the Courtroom: Which Interests? Whose Interests?

    In an apparent international first, the High Court has allowed a terminally ill 14-year-old to be cryopreserved after her death. The patient, JS, requested this, as she hoped one day to be reanimated and cured. Jackson J focused on the welfare (or best interests) of JS as she approached the end of her life and particularly on her (apparently) competent wish to be cryopreserved. I consider the interests involved in a decision to undergo cryonics, specifically exploring which interests and whose interests are engaged. Starting with autonomy interests, the judgment implicitly supported a relational account of autonomy, but was dominated by a subjective interpretation of autonomy, which prioritized JS's wishes. Questions nevertheless arise about whether the dying person is entitled to legislate for the reanimated person he or she might become. Temporal concerns also feature when we interpret welfare in terms of happiness, because the dying person and the (potential) future reanimated person might have different interests at different times. Finally, I widen the analysis to accommodate the interests of others, by exploring whether cryonics is in, or contrary to, the public interest. Utilizing different accounts of the public interest, I argue that the case for cryonics is not entirely made out. These observations on autonomy, happiness and the public interest combine to suggest that, although there may not be a decisive case for denying a wish like JS's, there is a case for caution, at least while we seek to clarify and resolve the different interests in issue. © The Author 2017.

    2007-12-01

    Engineering programs have been less successful than other professions in achieving gender equity. Analyses of gender differences in the attitudes and interests of engineering students may help illuminate ways to combat the underrepresentation of women in engineering. This study examined data collected from 863 engineering students who attended 15 American universities from fall 2005 through spring 2006 using an online survey. The survey was designed to understand the backgrounds, academic preparation, motivation, interests, and attitudes of engineering students. To determine whether males and females received different academic preparation prior to entering engineering, the survey examined participants' mathematics, science, and technical coursework taken in high school. The questions probed students' comfort and interest level in mathematics, science, and technology/engineering and investigated student interest in the three fundamental engineering activities by asking 49 design, build, and analyze questions on topics covering a variety of engineering disciplines. A combination of question formats was used including pre-categorized demographic information, 5-point Likert scales, and open-ended responses. Gender similarities and differences were identified and their implications were considered for the recruitment and retention of engineers. Female engineering students in this study were equally or better prepared than males to major in engineering based on the number and types of science and mathematics classes taken in high school. However, statistically significant gender differences were found in the attitudes and interests of engineering students. The difference in the comfort level, interest in learning, being able to demonstrate, or in performing stem skills depended on the question topic rather than gender. The areas with the highest comfort and interest level were often different for females and males. Several topics and curriculum areas of high interest to

    Patients with advanced cancer receiving palliative care often experience severe physical and psychosocial symptoms. However, there are limited resources for psychological and emotional support. Expressive writing has shown decreased anxiety level in young and healthy people suffering from a number of stressors. The purpose of this study was to determine the feasibility of expressive writing in patients receiving palliative care and the most suitable outcomes of expressive writing in this patient population. In this pilot study, patients were randomly assigned to either the expressive writing group (EW) or the neutral writing group (NW). Anxiety level before and after the writing session was compared between the two groups. Writing materials were content analyzed using standard qualitative research methods. A total of 24 patients (12 in EW and 12 in NW) were enrolled in the study between October 2006 and January 2007. Although the majority of patients (83%-100%) were able to complete all baseline assessments, poor adherence was observed during the follow-ups. Only 8% of patients completed the 2-week study. There was no significant difference in the State-Trait Anxiety Inventory (STAI) State-Anxiety scores at baseline, before and after each writing session between the EW and NW groups. Our rapid accrual suggests that palliative care patients are interested in participating in studies such as expressive writing. The high level of adherence to the baseline assessments indicates that these assessments were not particularly difficult for our patients to complete. Future studies may need to include patients with better performance status, better patient education, means of emotional expression (i.e., audio recording, telephone interview) and improved adherence. We conclude that clinical trials of expressive writing in the palliative care setting are not feasible unless they undergo major modification in methods compared to those previous reported in other patient

  3. Interests diffusion in social networks

    2015-10-01

    We provide a model for diffusion of interests in Social Networks (SNs). We demonstrate that the topology of the SN plays a crucial role in the dynamics of the individual interests. Understanding cultural phenomena on SNs and exploiting the implicit knowledge about their members is attracting the interest of different research communities both from the academic and the business side. The community of complexity science is devoting significant efforts to define laws, models, and theories, which, based on acquired knowledge, are able to predict future observations (e.g. success of a product). In the mean time, the semantic web community aims at engineering a new generation of advanced services by defining constructs, models and methods, adding a semantic layer to SNs. In this context, a leapfrog is expected to come from a hybrid approach merging the disciplines above. Along this line, this work focuses on the propagation of individual interests in social networks. The proposed framework consists of the following main components: a method to gather information about the members of the social networks; methods to perform some semantic analysis of the Domain of Interest; a procedure to infer members' interests; and an interests evolution theory to predict how the interests propagate in the network. As a result, one achieves an analytic tool to measure individual features, such as members' susceptibilities and authorities. Although the approach applies to any type of social network, here it is has been tested against the computer science research community. The DBLP (Digital Bibliography and Library Project) database has been elected as test-case since it provides the most comprehensive list of scientific production in this field.

    1989-06-01

    This paper examines the impact of post-1945 migration into Western, Middle, and Northern Europe from Southern Europe, Turkey, and Northern Africa, and migration to the traditional immigration countries by Asian and Latin American immigrants, on the social structures of receiving countries. Between 1955 and 1974, 1) traditional migration to the US and Australia became less important for European countries while traditional receiving countries accepted many immigrants from developing countries; and 2) rapid economic revival in Western and Northern Europe caused a considerable labor shortage which was filled by migrant workers especially from Southern Europe, Turkey, and Northern Africa, who stayed only until they reached their economic goals. Since 1974, job vacancies have declined and unemployment has soared. This employment crisis caused some migrants 1) to return to their countries of origin, 2) to bring the rest of their families to the receiving country, or 3) to lengthen their stay considerably. The number of refugees has also significantly increased since the mid-970s, as has the number of illegal migrants. After the mid-1970s, Europe began to experience integration problems. The different aspects of the impact of migration on social structures include 1) improvement of the housing situation for foreigners, 2) teaching migrants the language of the receiving country, 3) solving the unemployment problem of unskilled migrants, 4) improvement of educational and vocational qualifications of 2nd generation migrants, 5) development of programs to help unemployed wives of migrants to learn the language and meet indigenous women, 6) encouraging migrants to maintain their cultural identity and assisting them with reintegration if they return to their original country, 7) coping with the problems of refugees, and 8) solving the problems of illegal migration. Almost all receiving countries now severely restrict further immigration. [Those policies should result in

    The years of residency are the pillars of the subsequent practice in every medical specialty. The aim of our study is to evaluate the current situation, degree of involvement, main interests, and perceived quality of the training received by Spanish residents of neurology, specifically in the area of headache. A self-administered survey was designed by the Headache Study Group of the Spanish Society of Neurology (GECSEN) and was sent via e-mail to all residents who were members of the Society as of May 2015. Fifty-three residents completed the survey (N = 426, 12.4%): 6% were first year residents, 25.5% second year, 23.5% third year, and 45% fourth year residents, all from 13 different Spanish autonomous communities. The areas of greatest interest are, in this order: Vascular neurology, headache, and epilepsy. Of them, 85% believe that the area of headache is undervalued. More than half of residents (52.8%) do not rotate in specific Headache Units and only 35.8% complete their training dominating anaesthetic block and toxin infiltration techniques. Of them, 81.1% believe that research is scarce or absent; 69.8% have never made a poster/presentation, 79.3% have not published and only 15% collaborate on research projects in this area. Lastly, 40% believe that they have not received adequate training. Headache is among the areas that interest our residents the most; however, we believe that we must improve their training both at a patient healthcare level and as researchers. Thus, increasing the number of available courses, creating educational web pages, involving residents in research, and making a rotation in a specialised unit mandatory are among the fundamental objectives of the GECSEN.

    Full Text Available The Galileo system introduces an extremely wideband civil E5 signal for high precision navigation. The structure of the receiver for the E5 signal is complicated due to the signal complexity and the large bandwidth. It is possible to process the whole E5 signal or process separately E5a and E5b parts combining obtained results afterwards (we call here such method as piece-wise processing. The second procedure has three times worse standard deviation of the pseudorange then first one. The main goal of the paper is to present a design of an E5 receiver which we will call the economic E5 receiver (ecoE5. It is built from jointly controlled correlators for the processing of the E5a and E5b signals which are parts of the E5 signal. Control of these partial E5a and E5b correlators is realized by only one delay and one phase lock loops. The performance, i.e. the pseudorange noise and multipath errors, of the receiver equipped with the ecoE5, is only slightly worse (the standard deviation of the pseudorange noise is 10 - 20% larger than the performance of the optimal E5 receiver and it is much better than the performance of the receiver combining the piecewise (E5a and E5b measurements. The ecoE5 receiver hardware demands are about one quarter of the hardware demands of the classical E5 receiver.

  1. Rapidly rotating red giants

    Science.gov (United States)

    Gehan, Charlotte; Mosser, Benoît; Michel, Eric

    2017-10-01

    Stellar oscillations give seismic information on the internal properties of stars. Red giants are targets of interest since they present mixed modes, wich behave as pressure modes in the convective envelope and as gravity modes in the radiative core. Mixed modes thus directly probe red giant cores, and allow in particular the study of their mean core rotation. The high-quality data obtained by CoRoT and Kepler satellites represent an unprecedented perspective to obtain thousands of measurements of red giant core rotation, in order to improve our understanding of stellar physics in deep stellar interiors. We developed an automated method to obtain such core rotation measurements and validated it for stars on the red giant branch. In this work, we particularly focus on the specific application of this method to red giants having a rapid core rotation. They show complex spectra where it is tricky to disentangle rotational splittings from mixed-mode period spacings. We demonstrate that the method based on the identification of mode crossings is precise and efficient. The determination of the mean core rotation directly derives from the precise measurement of the asymptotic period spacing ΔΠ1 and of the frequency at which the crossing of the rotational components is observed.

These receivers are based on the low-barrier Schottky diodes. The approach to the design of the receivers on the basis of delta-doped low-barrier Schottky diodes with beam leads without bias is especially actively developing because for uncooled receivers of the microwave radiation these diodes have virtually no competition. The purpose of this work is to improve the main parameters and characteristics that determine the practical relevance of the receivers of mid-infrared electromagnetic radiation at the operating room temperature by modifying the electrodes configuration of the diode and optimizing the distance between them. Proposed original design solution of the integrated receiver of mid-infrared radiation on the basis of the low-barrier Schottky diodes with beam leads allows to effectively adjust its main parameters and characteristics. Simulation of the electromagnetic characteristics of the proposed receiver by using the software package HFSS with the basic algorithm of a finite element method which implemented to calculate the behavior of electromagnetic fields on an arbitrary geometry with a predetermined material properties have shown that when the inner parts of the electrodes of the low-barrier Schottky diode is performed in the concentric elliptical convex-concave shape, it can be reduce the reflection losses to -57.75 dB and the standing wave ratio to 1.003 while increasing the directivity up to 23 at a wavelength of 6.09 μm. At this time, the rounded radii of the inner parts of the anode and cathode electrodes are equal 212 nm and 318 nm respectively and the gap setting between them is 106 nm. These parameters will improve the efficiency of the developed infrared optical-promising and electronic equipment for various purposes intended for work in the mid-infrared wavelength range.

    Spiridon, Alex; Benzel, Dave; Dowla, Farid U.; Nekoogar, Faranak; Rosenbury, Erwin T.

    2007-12-04

    A novel technique and structure that maximizes the extraction of information from reference pulses for UWB-TR receivers is introduced. The scheme efficiently processes an incoming signal to suppress different types of UWB as well as non-UWB interference prior to signal detection. Such a method and system adds a feedback loop mechanism to enhance the signal-to-noise ratio of reference pulses in a conventional TR receiver. Moreover, sampling the second order statistical function such as, for example, the autocorrelation function (ACF) of the received signal and matching it to the ACF samples of the original pulses for each transmitted bit provides a more robust UWB communications method and system in the presence of channel distortions.

    Full Text Available The article scrutinizes the notion of feedback applicable in classrooms where team teaching is provided. The experience of giving and receiving feedback has been a good practice in cooperation between a U.S. Peace Corps volunteer and a Ukrainian counterpart. Giving and receiving feedback is an effective means of classroom observation that provides better insight into the process of teaching a foreign language. The article discusses the stages of feedback and explicates the notion of sharing experience between two teachers working simultaneously in the same classroom. The guidelines for giving and receiving feedback have been provided as well as the most commonly used vocabulary items have been listed. It has been proved that mutual feedback leads to improving teaching methods and using various teaching styles and techniques.

    2017-01-01

    A journalist reports to a voter on an unknown, policy-relevant state. Competing special interests can make claims that contradict the facts but seem credible to the voter. A reputational incentive to avoid taking sides leads the journalist to report special interests’ claims to the voter. In equilibrium, the voter can remain uninformed even when the journalist is perfectly informed. Communication is improved if the journalist discloses her partisan leanings. The model provides an account of persistent public ignorance on climate change that is consistent with narrative and quantitative evidence. PMID:28725092

  16. Scintillation-Hardened GPS Receiver

    Stephens, Donald R.

    2015-01-01

    CommLargo, Inc., has developed a scintillation-hardened Global Positioning System (GPS) receiver that improves reliability for low-orbit missions and complies with NASA's Space Telecommunications Radio System (STRS) architecture standards. A software-defined radio (SDR) implementation allows a single hardware element to function as either a conventional radio or as a GPS receiver, providing backup and redundancy for platforms such as the International Space Station (ISS) and high-value remote sensing platforms. The innovation's flexible SDR implementation reduces cost, weight, and power requirements. Scintillation hardening improves mission reliability and variability. In Phase I, CommLargo refactored an open-source GPS software package with Kalman filter-based tracking loops to improve performance during scintillation and also demonstrated improved navigation during a geomagnetic storm. In Phase II, the company generated a new field-programmable gate array (FPGA)-based GPS waveform to demonstrate on NASA's Space Communication and Navigation (SCaN) test bed.

    2016-01-01

    An optical correlation receiver is described that provides ultra-precise distance and/or time/pulse-width measurements even for weak (single photons) and short (femtosecond) optical signals. A new type of optical correlation receiver uses a fourth-order (intensity) interferometer to provide micron distance measurements even for weak (single photons) and short (femtosecond) optical signals. The optical correlator uses a low-noise-integrating detector that can resolve photon number. The correlation (range as a function of path delay) is calculated from the variance of the photon number of the difference of the optical signals on the two detectors. Our preliminary proof-of principle data (using a short-pulse diode laser transmitter) demonstrates tens of microns precision.

  1. FDAMA Section 114: Why the Renewed Interest?

    Science.gov (United States)

    Perfetto, Eleanor M; Burke, Laurie; Oehrlein, Elisabeth M; Gaballah, Mena

    2015-05-01

    The FDA regulates the use of information by biopharmaceutical companies in their promotional activities. Section 114 of the Food and Drug Administration Modernization Act of 1997 (FDAMA) was specifically designed to allow companies to more readily disseminate health care economic information (HCEI) to those who need it for formulary decision making. However, very little HCEI has been distributed promotionally under this provision over the past 17 years. There are recent discussions by stakeholders regarding the need for updates, revisions, or guidance regarding Section 114.In light of recent renewed interest in Section 114 of the FDAMA, the purpose of this commentary is to equip managed care decision makers with the information they need to understand and respond to industry communications that are governed by Section 114. This commentary reviews and synthesizes the regulatory history and language of the statute and changes to the promotion regulation generated by Section 114. It explores the reasons for the section's limited use to date, for recent renewed interest, and why changes by various stakeholders are suggested at this time. Also discussed is what managed care pharmacists need to know about Section 114, and suggestions are included regarding the active role pharmacists can play in this change process. Renewed interest in FDAMA Section 114 appears to stem largely from the increasingly visible and growing interest in comparative effectiveness research, the emergence of "big data," the expanding range of data sources available for deriving HCEI, and recent court decisions that might indicate a change in the regulatory environment. Various stakeholders are proposing recommendations regarding changes to FDAMA Section 114. Managed care pharmacists should be aware that companies are restricted when communicating HCEI promotional messages; this may mean seeing the use of FDAMA Section 114 as the "competent and reliable" effectiveness standard in promotion.

  2. Omnidirectional free-space optical receiver architecture

    Science.gov (United States)

    Murshid, Syed H.; Lovell, Gregory L.; Finch, Michael F.

    2013-05-01

    Free Space Optical (FSO) communication is the fusion of wireless technology and optical fiber communications systems. It has the potential of providing fiber optic data rates without the physical restraints of optical fiber cables. This endeavor presents a novel receiver structure with potential for omnidirectional free space optical communications. Interesting approaches for accomplishing omnidirectional free space lasercomm such as direct detection and solar blind non-line of sight UV scattering have been reported over the last few years. However, these technologies have resulted in limited distances of the order of 10 to 100 meters and data rates often limited to less than 1 Mb/s. This endeavor reports the architecture of an omnidirectional receiver setup by integrating an off the shelf detector and a fiber bundle, where the fiber bundle couples omnidirectional photons within its field of view and delivers these photons to the detector. The coupling of light from all directions into a detector is regulated by the cone of the acceptance angle of the fiber. Multiple fibers with overlapping acceptance angles provide the necessary coverage that may be needed to extract the optical signal from the free space optical channel. Simulated results showing the normalized power pattern of the system is presented to demonstrate omnidirectional potential of the structure. Theoretical power level versus distance plot for an FSO System employing On-O Keying (OOK) is also presented.

    To investigate the effects of non-inherited maternal antigen (NIMA) on clinical outcomes and immune recovery, especially of regulatory T cells (Tregs), in patients who underwent unmanipulated haploidentical transplantation. A retrospective cohort (n = 57) and a prospective cohort (n = 88) were included. All patients received haploidentical allografts from sibling donors. Reconstitution of immune subsets, including Tregs, was determined using multicolor flow cytometry. In the retrospective cohort, the cumulative incidence of grades II-IV acute GVHD in patients with NIMA-mismatched donors was significantly lower than that of cases with NIPA-mismatched donors (14.8% vs. 43.30%, p = 0.018). Patients with higher percentages of CD4 + CD25 + CD45RA + T cells (naive Tregs) within CD4 + T cells recovered on day 30 (≥1.55%) experienced a significantly lower incidence of grades II-IV acute GVHD than that of cases with lower percentages of naive Tregs (NIMA mismatch and the percentages of naive Tregs were associated with the incidence of grades II-IV acute GVHD [ p = 0.050, and 0.031, respectively]. In the prospective cohort, the association of NIMA mismatch [HR = 0.365, 95% CI, 0.169-0.786, p = 0.010] or higher percentages of naive Tregs recovered on day 30 (≥1.55%) [HR = 0.114, 95% CI, 0.027-0.479, p = 0.003] with a lower cumulative incidence of grades II-IV acute GVHD was further demonstrated. No effects of NIMA mismatch on chronic GVHD, transplant-related mortality, relapse, disease-free survival, or overall survival were found. Our results confirmed the role of NIMA mismatch in acute GVHD and provided the first demonstration, based on clinical data, that recovered Tregs may be involved in the effects of NIMA on acute GVHD in a haploidentical transplant setting.

    Andersen, Jørgen Bach; Frandsen, Aksel

    2005-01-01

    A receiving antenna with a matched load will always scatter some power. This paper sets an upper and a lower bound on the absorption efficiency (absorbed power over sum of absorbed and scattered powers), which lies between 0 and 100% depending on the directivities of the antenna and scatter...... patterns. It can approach 100% as closely as desired, although in practice this may not be an attractive solution. An example with a small endfire array of dipoles shows an efficiency of 93%. Several examples of small conical horn antennas are also given, and they all have absorption efficiencies less than...

    Full Text Available While pulmonary tuberculosis (PTB remains an important public health issue worldwide, there is an emerging interest in non-tuberculous mycobacteria (NTM which is responsible for opportunistic infections of the respiratory tract as well as other anatomical sites in both developed and developing countries. In this context the one goal of the clinical mycobacteriology laboratories is to provide physicians with an accurate identification of the mycobacterium as rapidly as possible. During the last ten years, several lines of laboratory tools have been developed in order to speed the isolation and identification of mycobacteria from clinical specimens. Chiefly, the composition of culture medium was renewed along with the protocol of incubation in order to recover Mycobacterium tuberculosis (MTB micro-colonies as soon as 48 h after the inoculation of the specimen. MALDI-TOF rapid identification is clearly the tool to be implemented in the laboratory for the rapid identification of the micro-colonies. Also, molecular tools and genomics are necessary in order to depict new mycobacteria species, including those of the Mycobacterium abscessus complex and the Mycobacterium avium complex. All these tools and their connections will be presented during this conference.

  9. Common approach to common interests

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2001-06-01

    In referring to issues confronting the energy field in this region and options to be exercised in the future, I would like to mention the fundamental condition of the utmost importance. That can be summed up as follows: any subject in energy area can never be solved by one country alone, given the geographical and geopolitical characteristics intrinsically possessed by energy. So, a regional approach is needed and it is especially necessary for the main players in the region to jointly address problems common to them. Though it may be a matter to be pursued in the distant future, I am personally dreaming a 'Common Energy Market for Northeast Asia,' in which member countries' interests are adjusted so that the market can be integrated and the region can become a most economically efficient market, thus formulating an effective power to encounter the outside. It should be noted that Europe needed forty years to integrate its market as the unified common market. It is necessary for us to follow a number of steps over the period to eventually materialize our common market concept, too. Now is the time for us to take a first step to lay the foundation for our descendants to enjoy prosperity from such a common market.

    CERN Document Server

    Jamin, Olivier

    2014-01-01

    This book discusses the trade-offs involved in designing direct RF digitization receivers for the radio frequency and digital signal processing domains.  A system-level framework is developed, quantifying the relevant impairments of the signal processing chain, through a comprehensive system-level analysis.  Special focus is given to noise analysis (thermal noise, quantization noise, saturation noise, signal-dependent noise), broadband non-linear distortion analysis, including the impact of the sampling strategy (low-pass, band-pass), analysis of time-interleaved ADC channel mismatches, sampling clock purity and digital channel selection. The system-level framework described is applied to the design of a cable multi-channel RF direct digitization receiver. An optimum RF signal conditioning, and some algorithms (automatic gain control loop, RF front-end amplitude equalization control loop) are used to relax the requirements of a 2.7GHz 11-bit ADC. A two-chip implementation is presented, using BiCMOS and 65nm...

  20. Low Complexity Receiver Design for MIMO-Radar

    KAUST Repository

    Ahmed, Sajid

    2012-09-08

    In this work, an algorithm for the multiple-input multiple-output (MIMO) radar is proposed. It has low computational complexity compared to the available schemes, and relatively low side-lobe-levels in the receive beampattern compared to the phased-array and MIMO-radar. In the proposed algorithm, the received signal vector of MIMO-radar is divided into sub-vectors, and each sub-vector is multiplied with the corresponding weight vector. The number of sub-vectors and weight vectors are optimally found to maximise the received signal power from the target of interest direction. The proposed scheme can be effectively applied in passive radars to minimise the side-lobe levels and place deep nulls for interferers in the receive beampattern. Simulation results show that the proposed scheme has relatively lower side lobe levels and better detection capabilities compared to MIMO-radar and phased-array.

  1. Rapid Airplane Parametric Input Design (RAPID)

    Science.gov (United States)

    Smith, Robert E.

    1995-01-01

    RAPID is a methodology and software system to define a class of airplane configurations and directly evaluate surface grids, volume grids, and grid sensitivity on and about the configurations. A distinguishing characteristic which separates RAPID from other airplane surface modellers is that the output grids and grid sensitivity are directly applicable in CFD analysis. A small set of design parameters and grid control parameters govern the process which is incorporated into interactive software for 'real time' visual analysis and into batch software for the application of optimization technology. The computed surface grids and volume grids are suitable for a wide range of Computational Fluid Dynamics (CFD) simulation. The general airplane configuration has wing, fuselage, horizontal tail, and vertical tail components. The double-delta wing and tail components are manifested by solving a fourth order partial differential equation (PDE) subject to Dirichlet and Neumann boundary conditions. The design parameters are incorporated into the boundary conditions and therefore govern the shapes of the surfaces. The PDE solution yields a smooth transition between boundaries. Surface grids suitable for CFD calculation are created by establishing an H-type topology about the configuration and incorporating grid spacing functions in the PDE equation for the lifting components and the fuselage definition equations. User specified grid parameters govern the location and degree of grid concentration. A two-block volume grid about a configuration is calculated using the Control Point Form (CPF) technique. The interactive software, which runs on Silicon Graphics IRIS workstations, allows design parameters to be continuously varied and the resulting surface grid to be observed in real time. The batch software computes both the surface and volume grids and also computes the sensitivity of the output grid with respect to the input design parameters by applying the precompiler tool

    Few systematic assessment tools are available to organ procurement organizations (OPOs) for evaluating donation climates of hospitals in their donation service areas (DSAs). The Rapid Assessment of hospital Procurement barriers in Donation (RAPiD) was developed for OPO hospital development staff to assess the organ donation climate of hospitals. To implement a national test of the RAPiD to examine its efficacy and usability by OPO hospital development staff. Two-arm randomized design, comparing implementation of RAPiD protocol between qualitatively trained researchers (n = 7) and OPO hospital development staff (n = 24); all evaluators received the same training assessments of high-yield hospitals. A total of 77 hospitals in DSAs of 8 OPOs. A total of 2552 health-care providers (HCPs) in high organ donor potential units. Twenty-four donation-related attitudes, knowledge, and behaviors. More HCPs interviewed in the autonomous condition were positive toward the concept of organ donation. However, HCPs in the assisted condition were more candid about and critical of the OPO. As for knowledge, fewer HCPs in the autonomous condition reported familiarity with the donation process, need for donors, and generally accepted timely referral criteria. With respect to behaviors, more respondents in the autonomous condition reported frequent or occasional contact with the OPO and routine or occasional referral criteria use. Due to issues of bias, inadequate research experience, conflicts of interest, and ongoing OPO hospital development initiatives, the RAPiD's usability by OPO-based hospital development staff is questionable and not recommended in its current form. A next generation of the RAPiD is described for future consideration. © 2016, NATCO.

  3. Binary classification of items of interest in a repeatable process

    2015-01-06

    A system includes host and learning machines. Each machine has a processor in electrical communication with at least one sensor. Instructions for predicting a binary quality status of an item of interest during a repeatable process are recorded in memory. The binary quality status includes passing and failing binary classes. The learning machine receives signals from the at least one sensor and identifies candidate features. Features are extracted from the candidate features, each more predictive of the binary quality status. The extracted features are mapped to a dimensional space having a number of dimensions proportional to the number of extracted features. The dimensional space includes most of the passing class and excludes at least 90 percent of the failing class. Received signals are compared to the boundaries of the recorded dimensional space to predict, in real time, the binary quality status of a subsequent item of interest.

    2005-06-01

    This work presents a simple differentially BPSK receiver front-end using a novel schema without the need of an explicit carrier recovery system. The main principle of operation is the conversion of the incoming BPSK signal into an ASK signal having the same modulation pattern. Two versions of the system have been designed. One is intended to work at the 433.92 MHz ISM band and the other at 2 GHz frequency band. Accordingly, two prototypes of the system core, the BPSK to ASK converter circuit, have been implemented and tested. First a hybrid version for the low frequency operation and, second a multi chip module (MCM) for the 2 GHz frequency band. The system performance has been evaluated using Agilent Technologies Advanced Design System (ADS) platform. The ability to jointly perform system, circuit and EM simulations and co-simulations is the main advantage of this design tool. Obtained results indicate that modulation rates up to 20 Mbits/s for the hybrid version and up to 80 Mbits/s for the MCM version can be reached.

    Patient advocacy organizations (PAOs) are influential health care stakeholders that provide direct counseling and education for patients, engage in policy advocacy, and shape research agendas. Many PAOs report having financial relationships with for-profit industry, yet little is known about the nature of these relationships. To describe the nature of industry funding and partnerships between PAOs and for-profit companies in the United States. A survey was conducted from September 1, 2013, to June 30, 2014, of a nationally representative random sample of 439 PAO leaders, representing 5.6% of 7865 PAOs identified in the United States. Survey questions addressed the nature of their activities, their financial relationships with industry, and the perceived effectiveness of their conflict of interest policies. Amount and sources of revenue as well as organizational experiences with and policies regarding financial conflict of interest. Of the 439 surveys mailed to PAO leaders, 289 (65.8%) were returned with at least 80% of the questions answered. The PAOs varied widely in terms of size, funding, activities, and disease focus. The median total revenue among responding organizations was $299 140 (interquartile range, $70 000-$1 200 000). A total of 165 of 245 PAOs (67.3%) reported receiving industry funding, with 19 of 160 PAOs (11.9%) receiving more than half of their funding from industry. Among the subset of PAOs that received industry funding, the median amount was $50 000 (interquartile range, $15 000-$200 000); the median proportion of industry support derived from the pharmaceutical, device, and/or biotechnology sectors was 45% (interquartile range, 0%-100%). A total of 220 of 269 respondents (81.8%) indicated that conflicts of interest are very or moderately relevant to PAOs, and 94 of 171 (55.0%) believed that their organizations' conflict of interest policies were very good. A total of 22 of 285 PAO leaders (7.7%) perceived pressure to conform

  8. RAPID3? Aptly named!

    Science.gov (United States)

    Berthelot, J-M

    2014-01-01

    The RAPID3 score is the sum of three 0-10 patient self-report scores: pain, functional impairment on MDHAQ, and patient global estimate. It requires 5 seconds for scoring and can be used in all rheumatologic conditions, although it has mostly been used in rheumatoid arthritis where cutoffs for low disease activity (12/30) have been set. A RAPID3 score of ≤ 3/30 with 1 or 0 swollen joints (RAPID3 ≤ 3 + ≤ SJ1) provides remission criteria comparable to Boolean, SDAI, CDAI, and DAS28 remission criteria, in far less time than a formal joint count. RAPID3 performs as well as the DAS28 in separating active drugs from placebos in clinical trials. RAPID3 also predicts subsequent structural disease progression. RAPID3 can be determined at short intervals at home, allowing the determination of the area under the curve of disease activity between two visits and flare detection. However, RAPID3 should not be seen as a substitute for DAS28 and face to face visits in routine care. Monitoring patient status with only self-report information without a rheumatologist's advice (including joints and physical examination, and consideration of imaging and laboratory tests) may indeed be as undesirable for most patients than joint examination without a patient questionnaire. Conversely, combining the RAPID3 and the DAS28 may consist in faster or more sensitive confirmation that a medication is effective. Similarly, better enquiring of most important concerns of patients (pain, functional status and overall opinion on their disorder) should reinforces patients' confidence in their rheumatologist and treatments.

    Full Text Available A S. mansoni adult worm cDNA expression library was screened with sera from baboons in a early phase after infection. The clones that were positive with the early infection sera were examined for reactivity with pre-infection sera and heterologous infection sera. In order to discriminate a positive antibody reaction from the reactivity due to residual anti-E. coli antibodies, an unrelated cDNA clone was plated with the positive clone. The unrelated clone provided the negative background and the contrast necessary to discern a positive antibody reaction. In this way, we were able to eliminate selected clones that were positive with the pre-infection sera or heterologous infection sera. This characterization of the expression library clones enabled us to quickly target only clones with the desired pattern of antibody reactivity for sequencing, subcloning, and expressingUma biblioteca de expressão de cDNA de verme adulto de S. mansoni foi selecionada utilizando-se soros de macacos babuínos em fase inicial da infecção. Os clones que reagiram positivamente com os soros de infecção recente foram examinados quanto à reatividade contra soros normais e soros de infecção heteróloga. Com a finalidade de se conseguir melhor discriminação entre reatividade positiva com o anticorpo específico e aquela devido aos anticorpos anti-E. coli residuais, um clone de cDNA não relacionado ao S. mansoni foi plaqueado em mistura com o clone positivo. O plano de fundo negativo proporcionado pelo clone não relacionado forneceu o contraste necessário para discriminar a reação positiva específica. Esta metodologia de caracterização dos clones de expressão permite alcançar rapidamente os clones que apresentam o perfil de reatividade desejada, para posterior sequenciamento, subclonagem e expressão

  11. [Rapid diagnostic test for malaria].

    Science.gov (United States)

    Houzé, S

    2017-02-01

    The rapid diagnostic tests (RDTs) whose main interest lies in their implementation without special equipment by unskilled personnel have grown significantly over the past fifteen years to diagnose malaria. They rely on the detection of specific Plasmodium proteins, PfHRP2, pLDH and aldolase. If the detection of PfHRP2 has very good sensitivity for the diagnosis of Plasmodium falciparum malaria, the detection of pLDH or aldolase is less efficient for other species, leaving its place to the reference microscopic diagnosis. RDT could not generally be used to monitor therapeutic efficacy because they can remain positive after clinical and parasitological cure. Furthermore, the development of the use of these tests has highlighted the need for quality assurance programs to monitor their production as their use.

  12. Self-interest and pro-environmental behaviour

    Evans, Laurel; Maio, Gregory R.; Corner, Adam; Hodgetts, Carl J.; Ahmed, Sameera; Hahn, Ulrike

    2013-02-01

    Inspired by the principles used to market physical products, campaigns to promote pro-environmental behaviour have increasingly emphasized self-interested (for example, economic) reasons for engaging with a self-transcendent cause (that is, protecting the environment). Yet, psychological evidence about values and behaviour suggests that giving self-interested reasons, rather than self-transcending reasons, to carry out a self-transcending action should be ineffective at increasing self-transcending behaviour more generally. In other words, such a campaign may fail to cause spillover, or an increase in other, different environmental behaviours. Here we show that recycling rates are dependent on the information participants receive about a separate environmental behaviour, car-sharing (carpooling in the USA). In two experiments, we found that recycling was significantly higher than control when participants received environmental information about car-sharing, but was no different from control when they received financial information or (in experiment 2) received both financial and environmental information. Our results suggest that, congruent with value theory, positive spillover from one environmental message to another behaviour (car-sharing to recycling) may occur primarily when self-transcending reasons alone are made salient.

  13. Rapid generalization in phonotactic learning

    Directory of Open Access Journals (Sweden)

    Tal Linzen

    2017-10-01

    Full Text Available Speakers judge novel strings to be better potential words of their language if those strings consist of sound sequences that are attested in the language. These intuitions are often generalized to new sequences that share some properties with attested ones: Participants exposed to an artificial language where all words start with the voiced stops [b] and [d] will prefer words that start with other voiced stops (e.g., [g] to words that start with vowels or nasals. The current study tracks the evolution of generalization across sounds during the early stages of artificial language learning. In Experiments 1 and 2, participants received varying amounts of exposure to an artificial language. Learners rapidly generalized to new sounds: In fact, following short exposure to the language, attested patterns were not distinguished from unattested patterns that were similar in their phonological properties to the attested ones. Following additional exposure, participants showed an increasing preference for attested sounds, alongside sustained generalization to unattested ones. Finally, Experiment 3 tested whether participants can rapidly generalize to new sounds based on a single type of sound. We discuss the implications of our results for computational models of phonotactic learning.

    2013-01-01

    Full Text Available Severe cutaneous reactions with potentially fatal outcomes can have many different causes. The Stevens-Johnson syndrome (SJS and toxic epidermal necrolysis (TEN are rare. They are characterized by a low incidence but high mortality, and drugs are most commonly implicated. Urgent active therapy is required. Prompt recognition and withdrawal of suspect drug and rapid intervention can result in favourable outcome. No further international guidelines for treatment exist, and much of the treatment relies on old or experimental concepts with no scientific evidence. We report on a 54-year-old man experiencing rapidly developing drug-induced severe TEN and presented multiorgan failure involving the respiratory and circulatory system, coagulopathy, and renal insufficiency. Detachment counted 30% of total body surface area (TBSA. SCORTEN = 5, indicating a mortality rate >90%. The patient was sedated and mechanically ventilated, supported with fluids and inotropes to maintain a stable circulation. Component therapy was guided by thromboelastography (TEG. The patient received plasmapheresis, and shock reversal treatment was initiated. He was transferred to a specialized intensive care burn unit within 24 hours from admittance. The initial care was continued, and hemodialysis was started. Pulmonary, circulatory, and renal sequelae resolved with intensive care, and re-epithelialization progressed slowly. The patient was discharged home on hospital day 19.

An interesting pattern emerged. While the level of interest in astrology remained relatively stable over the course of two centuries, interest in phrenology rose rapidly in the early 1800s but then declined. Reasons for this pattern are discussed.

  1. Pricing real estate index options under stochastic interest rates

    Gong, Pu; Dai, Jun

    2017-08-01

    Real estate derivatives as new financial instruments are not merely risk management tools but also provide a novel way to gain exposure to real estate assets without buying or selling the physical assets. Although real estate derivatives market has exhibited a rapid development in recent years, the valuation challenge of real estate derivatives remains a great obstacle for further development in this market. In this paper, we derive a partial differential equation contingent on a real estate index in a stochastic interest rate environment and propose a modified finite difference method that adopts the non-uniform grids to solve this problem. Numerical results confirm the efficiency of the method and indicate that constant interest rate models lead to the mispricing of options and the effects of stochastic interest rates on option prices depend on whether the term structure of interest rates is rising or falling. Finally, we have investigated and compared the different effects of stochastic interest rates on European and American option prices.

  3. Receiver buffer requirement for video streaming over TCP

    Science.gov (United States)

    Kim, Taehyun; Ammar, Mostafa H.

    2006-01-01

    TCP is one of the most widely used transport protocols for video streaming. However, the rate variability of TCP makes it difficult to provide good video quality. To accommodate the variability, video streaming applications require receiver-side buffering. In current practice, however, there are no systematic guidelines for the provisioning of the receiver buffer, and smooth playout is insured through over-provisioning. In this work, we are interested in memory-constrained applications where it is important to determine the right size of receiver buffer in order to insure a prescribed video quality. To that end, we characterize video streaming over TCP in a systematic and quantitative manner. We first model a video streaming system analytically and derive an expression of receiver buffer requirement based on the model. Our analysis shows that the receiver buffer requirement is determined by the network characteristics and desired video quality. Experimental results validate our model and demonstrate that the receiver buffer requirement achieves desired video quality.

    1998-05-09

    The direct connection of information, captured in forms such as CAD databases, to the factory floor is enabling a revolution in manufacturing. Rapid response to very dynamic market conditions is becoming the norm rather than the exception. In order to provide economical rapid fabrication of small numbers of variable products, one must design with manufacturing constraints in mind. In addition, flexible manufacturing systems must be programmed automatically to reduce the time for product change over in the factory and eliminate human errors. Sensor based machine control is needed to adapt idealized, model based machine programs to uncontrolled variables such as the condition of raw materials and fabrication tolerances.

    1988-01-01

    New Nb-base alloys are of interest for aerospace structural applications at high temperatures, viz, 800 to 1650 C. Fundamental information regarding the effects of rapid solidification in achieving greatly refined microstructures, extended solid solubility, suppression of embrittling equilibrium phases, and formation of new phases is desired in a number of Nb-X alloys. The microstructures and selected properties of Nb-Si and other Nb-base alloys are presented for materials both rapidly quenched from the equilibrium liquidus and rapidly solidified following deep supercooling. Electromagnetic levitation was used to achieve melting and supercooling in a containerless inert gas environment. A variety of solidification conditions were employed including splatting or drop casting of supercooled samples. The morphology and composition of phases formed are discussed in terms of both solidification history and bulk composition.

    1990-06-01

    Test-retest reliability data gathered from 83 sources (62 independent samples) were analyzed using a multiple-regression method to estimate the effects of several factors on the temporal stability of occupational interest inventories. Seven self-report inventories were examined--the Act Interest Inventory, the Career Assessment Inventory, the California Occupational Preference System Interest Survey, the Strong Vocational Interest Blank, and the Strong-Campbell Interest Inventory, Form T325 of the Strong Vocational Interest Blank. Samples encompassed a wide range of subjects. Subjects' ages and retest intervals were significant predictors of reliability. Number of items and homogeneity had anomalous relations with stability. Subjects' sex and sample size did not significantly affect reliability. A summary table provides expected reliability coefficients tabulated for combinations of age by test-retest interval.

    2004-09-01

    This report describes both a general methodology and some specific examples of passive radio receivers. A passive radio receiver uses no direct electrical power but makes sole use of the power available in the radio spectrum. These radio receivers are suitable as low data-rate receivers or passive alerting devices for standard, high power radio receivers. Some zero-power radio architectures exhibit significant improvements in range with the addition of very low power amplifiers or signal processing electronics. These ultra-low power radios are also discussed and compared to the purely zero-power approaches.

  19. Investigating Situational Interest in Primary Science Lessons

    2015-12-01

    Pupils' interest has been one of the major concerns in science education research because it can be seen as a gateway to more personalised forms of interest and motivation. However, methods to investigate situational interest in science teaching and learning are not broadly examined. This study compares the pupils' observed situational interest and their expressed situational interest. One class of Finnish fourth-graders (N = 22, age 9-10 years) participated in a heat transfer lesson. The lesson encompassed an interactive demonstration with a thermal camera, teacher-led discussions and the conduct and presentation of a collaborative inquiry task. Pupils expressed their interest levels (scale: 1 = very boring, 5 = very interesting) by using an electronic response system called a 'clicker'. The measurement took place 15 times during the lesson, with 1 measurement being just a rehearsal. The lesson was video recorded, and visible aspects of interest at the measurement time points were analysed. Reported and observational data were compared. In most cases, the observations did not yield data compatible with the pupils' own evaluations, indicating that most pupils' expressed interest is not easily interpreted through observation of their facial expressions and behaviour. In general, the interest of the group as a whole seems to diminish during the lesson. We argue that in order to maintain and increase pupils' interest, their evaluations should be taken into account in lesson planning. Video-based research might also be further enriched and validated by employing the participants' own expressions. The clicker is a suitable means of collecting primary pupils' experiences concerning their interest levels.

    Conflict of interest is common in the practice of medicine, and likely more so in the practice of sports medicine at the highest levels of competition. Two areas where conflict of interest frequently manifest in sports medicine are confidentiality and clinical decision making. Confidentiality can be challenging by the team physician's dual responsibilities to the player-patient and the team. Clinical decision making, traditionally associated with a patient's long term health interests, can be complicated by short term interests rooted in pursuit of winning. These issues are reviewed, hopefully to increase awareness in clinicians who find themselves in these unique situations. Copyright © 2016 Elsevier Inc. All rights reserved.

  4. Rapid Detection of Pathogens

    Energy Technology Data Exchange (ETDEWEB)

    David Perlin

    2005-08-14

    Pathogen identification is a crucial first defense against bioterrorism. A major emphasis of our national biodefense strategy is to establish fast, accurate and sensitive assays for diagnosis of infectious diseases agents. Such assays will ensure early and appropriate treatment of infected patients. Rapid diagnostics can also support infection control measures, which monitor and limit the spread of infectious diseases agents. Many select agents are highly transmissible in the early stages of disease, and it is critical to identify infected patients and limit the risk to the remainder of the population and to stem potential panic in the general population. Nucleic acid-based molecular approaches for identification overcome many of the deficiencies associated with conventional culture methods by exploiting both large- and small-scale genomic differences between organisms. PCR-based amplification of highly conserved ribosomal RNA (rRNA) genes, intergenic sequences, and specific toxin genes is currently the most reliable approach for bacterial, fungal and many viral pathogenic agents. When combined with fluorescence-based oligonucleotide detection systems, this approach provides real-time, quantitative, high fidelity analysis capable of single nucleotide allelic discrimination (4). These probe systems offer rapid turn around time (<2 h) and are suitable for high throughput, automated multiplex operations that are critical for clinical diagnostic laboratories. In this pilot program, we have used molecular beacon technology invented at the Public health Research Institute to develop a new generation of molecular probes to rapidly detect important agents of infectious diseases. We have also developed protocols to rapidly extract nucleic acids from a variety of clinical specimen including and blood and tissue to for detection in the molecular assays. This work represented a cooperative research development program between the Kramer-Tyagi/Perlin labs on probe development

    Full Text Available The evidence for Juan Ramon's interest in Pater, which began around 1920 and was still active twenty years later, is discussed in this paper. Pater's view of death and dying and his attitude toward the decadent persona are described in so far as they indicate the spiritual affinity that exists between him and Juan Ramón. Pater's aesthetic idealism, and the presence of similar ideals in Juan Ramon's own work are then examined. The second part of the paper concentrates on the great interest Juan Ramón took in Pater's evocation of the Mona Lisa. The potential impact of the aesthetic idealism inherent in this passage, its Platonism in particular, receives special analysis in the light of Espacio , and in consideration of Juan Ramon's 1943 remark: "I am, have been, and always will be a Platonist."

    The aim of the present mixed-method study was to investigate task-based situational interest of sixth grade students (n = 46), between 12 and 14 years old, during an eight-week engineering design programme in a Science & Technology-class. Students' interests were investigated by means of a descriptive interpretative analysis of qualitative data from classroom observations and informal interviews. The analysis was complemented by a self-report survey to validate findings and determine prevalence. The analysis revealed four main sources of interest: designing inventions, trial-and-error experimentation, achieved functionality of invention, and collaboration. These sources differ in terms of stimuli factors, such as novelty, autonomy (choice), social involvement, self-generation of interest, and task goal orientation. The study shows that design tasks stimulated interest, but only to the extent that students were able to self-regulate their learning strategies.

    2014-01-01

    A randomized control trial comparing two social communication treatments for children with autism spectrum disorder examined the effect of treatment on object interest. Thirty-two children, 18–60 months, were randomly assigned to the Picture Exchange Communication System (PECS) or Responsive Education and Prelinguistic Milieu Teaching (RPMT) condition. Assessment of object interest was conducted in an unstructured play session with different toys, activities, adult, and location than experienced in treatment. Results indicated children in the RPMT condition showed greater increases in object interest as compared to children in the PECS condition. Because child characteristics such as interest in objects may influence response to interventions using object play as contexts for treatment, it is important to improve our understanding of whether intervention can affect object interest.

    2009-11-01

    Increasing numbers of patients are expressing an interest in mesotherapy as a method of reducing body fat. Cutaneous infections due to rapidly growing mycobacteria are a common complication of such procedures. We followed up patients who had developed cutaneous infections after undergoing mesotherapy during the period October 2006-January 2007. Sixteen patients were infected after mesotherapy injections performed by the same physician. All patients presented with painful, erythematous, draining subcutaneous nodules at the injection sites. All patients were treated with surgical drainage. Microbiological examination was performed on specimens that were obtained before and during the surgical procedure. Direct examination of skin smears demonstrated acid-fast bacilli in 25% of the specimens that were obtained before the procedure and 37% of the specimens obtained during the procedure; culture results were positive in 75% of the patients. Mycobacterium chelonae was identified in 11 patients, and Mycobacterium frederiksbergense was identified in 2 patients. Fourteen patients were treated with antibiotics, 6 received triple therapy as first-line treatment (tigecycline, tobramycin, and clarithromycin), and 8 received dual therapy (clarithromycin and ciprofloxacin). The mean duration of treatment was 14 weeks (range, 1-24 weeks). All of the patients except 1 were fully recovered 2 years after the onset of infection, with the mean time to healing estimated at 6.2 months (range, 1-15 months). This series of rapidly growing mycobacterial cutaneous infections highlights the difficulties in treating such infections and suggests that in vitro susceptibility to antibiotics does not accurately predict their clinical efficacy.

    Full Text Available Access to microcredit can have a beneficial effect on the well-being of low-income households excluded from the traditional banking system. It allows this population to receive affordable financial services to help them to meet their needs and to improve their living conditions. However to provide access to credit, microfinance institutions should ensure not only their social mission but also commercial and financial mission to enable the institution to perpetuate and become self-sufficient. To this end, MFIs (microfinance institutions must apply an interest rate that covers their costs and risk, while generating profits, Also microentrepreneurs need, to this end, to ensure the profitability of their activities. This paper presents the microfinance sector in Morocco. It focuses then on the interest rate applied by the Moroccan microfinance institutions; it provides also a comparative study between Morocco and other comparable countries in terms of interest rates charged to borrowers. Finally, this article presents a stochastic model of the interest rate in microcredit built in random loan repayment periods and on a real example of the program of loans of microfinance institution in Morocco

    Studies were performed using data collected from an array of 50 seismic stations in Southern Peru. The seismic array runs perpendicular to the trench between Mollendo and Juliaca and is part of a UCLA CENS (Center for Embedded Networked Systems) project. This area is of interest because Southern Peru represents a transition between subduction with a dip angle of around 30 degrees and shallow subduction to the north. The current line is located in a region with steeper subduction while a second line is planned between Cusco and Juliaca to study the transition between flat and steep subduction. A third line from Cusco to the coast will study the region with shallow subduction. Based on teleseismic receiver functions (RFs), the crustal thickness gradually thickens to a depth of approximately 70km beneath the Altiplano. A mid-crustal structure has also been observed at a depth of close to 40km. This may represent a remnant of the original Moho before the rapid uplift of the Altiplano, or may indicate some type of underplating episode. Images also show the subducting slab, which is best imaged by RFs based on PKP phases. Additional information on the subducted slab and overlying crust is being sought from PP phases, S-wave RFs, and undersided reflections. The goal of this study is to compare the structure and properties of the “normally” subducting slab with the “flat” slab the will be imaged on the third line.

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

    I will present results from the 1.5Ms XMM-Newton observing campaign on the most X-ray variable AGN, IRAS 13224-3809. We find a series of nine absorption lines with a velocity of 0.24c from an ultra-fast outflow. For the first time, we are able to see extremely rapid variability of the UFO features, and can link this to the X-ray variability from the inner accretion disk. We find a clear flux dependence of the outflow features, suggesting that the wind is ionized by increasing X-ray emission.

    In order to support advanced manufacturing, Sandia has acquired the capability to produce plastic prototypes using stereolithography. Currently, these prototypes are used mainly to verify part geometry and ``fit and form`` checks. This project investigates methods for rapidly testing these plastic prototypes, and inferring from prototype test data actual metal part performance and behavior. Performances examined include static load/stress response, and structural dynamic (modal) and vibration behavior. The integration of advanced non-contacting measurement techniques including scanning laser velocimetry, laser holography, and thermoelasticity into testing of these prototypes is described. Photoelastic properties of the epoxy prototypes to reveal full field stress/strain fields are also explored.

  16. The declining interest in an academic career.

    Directory of Open Access Journals (Sweden)

    Michael Roach

    Full Text Available There is increasing evidence that science & engineering PhD students lose interest in an academic career over the course of graduate training. It is not clear, however, whether this decline reflects students being discouraged from pursuing an academic career by the challenges of obtaining a faculty job or whether it reflects more fundamental changes in students' career goals for reasons other than the academic labor market. We examine this question using a longitudinal survey that follows a cohort of PhD students from 39 U.S. research universities over the course of graduate training to document changes in career preferences and to explore potential drivers of such changes. We report two main results. First, although the vast majority of students start the PhD interested in an academic research career, over time 55% of all students remain interested while 25% lose interest entirely. In addition, 15% of all students were never interested in an academic career during their PhD program, while 5% become more interested. Thus, the declining interest in an academic career is not a general phenomenon across all PhD students, but rather reflects a divergence between those students who remain highly interested in an academic career and other students who are no longer interested in one. Second, we show that the decline we observe is not driven by expectations of academic job availability, nor by related factors such as postdoctoral requirements or the availability of research funding. Instead, the decline appears partly due to the misalignment between students' changing preferences for specific job attributes on the one hand, and the nature of the academic research career itself on the other. Changes in students' perceptions of their own research ability also play a role, while publications do not. We discuss implications for scientific labor markets, PhD career development programs, and science policy.

    A current debate about conflicts of interest related to biomedical research is to question whether the focus on financial conflicts of interest overshadows "nonfinancial" interests that could put scientific judgment at equal or greater risk of bias. There is substantial evidence that financial conflicts of interest such as commercial sponsorship of research and investigators lead to systematic biases in scientific research at all stages of the research process. Conflation of "conflicts of interest" with "interests" in general serves to muddy the waters about how to manage conflicts of interest. We call for heightened disclosure of conflicts of interest and policy action beyond disclosure as the sole management strategy. We propose a different strategy to manage interests more broadly to ensure fair representation and accountability.

    2014-01-01

    Objective: Our paper presents findings from the first population survey of stigma in Canada using a new measure of stigma. Empirical objectives are to provide a descriptive profile of Canadian’s expectations that people will devalue and discriminate against someone with depression, and to explore the relation between experiences of being stigmatized in the year prior to the survey among people having been treated for a mental illness with a selected number of sociodemographic and mental health–related variables. Method: Data were collected by Statistics Canada using a rapid response format on a representative sample of Canadians (n = 10 389) during May and June of 2010. Public expectations of stigma and personal experiences of stigma in the subgroup receiving treatment for a mental illness were measured. Results: Over one-half of the sample endorsed 1 or more of the devaluation discrimination items, indicating that they believed Canadians would stigmatize someone with depression. The item most frequently endorsed concerned employers not considering an application from someone who has had depression. Over one-third of people who had received treatment in the year prior to the survey reported discrimination in 1 or more life domains. Experiences of discrimination were strongly associated with perceptions that Canadians would devalue someone with depression, younger age (12 to 15 years), and self-reported poor general mental health. Conclusions: The Mental Health Experiences Module reflects an important partnership between 2 national organizations that will help Canada fulfill its monitoring obligations under the United Nations Convention on the Rights of Persons with Disabilities and provide a legacy to researchers and policy-makers who are interested in monitoring changes in stigma over time.

    Full Text Available Abstract Background Among the greatest challenges for biology in the 21st century is inference of the tree of life. Interest in, and progress toward, this goal has increased dramatically with the growing availability of molecular sequence data. However, we have very little sense, for any major clade, of how much progress has been made in resolving a full tree of life and the scope of work that remains. A series of challenges stand in the way of completing this task but, at the most basic level, progress is limited by data: a limited fraction of the world's biodiversity has been incorporated into a phylogenetic analysis. More troubling is our poor understanding of what fraction of the tree of life is understood and how quickly research is adding to this knowledge. Here we measure the rate of progress on the tree of life for one clade of particular research interest, the vertebrates. Results Using an automated phylogenetic approach, we analyse all available molecular data for a large sample of vertebrate diversity, comprising nearly 12,000 species and 210,000 sequences. Our results indicate that progress has been rapid, increasing polynomially during the age of molecular systematics. It is also skewed, with birds and mammals receiving the most attention and marine organisms accumulating far fewer data and a slower rate of increase in phylogenetic resolution than terrestrial taxa. We analyse the contributors to this phylogenetic progress and make recommendations for future work. Conclusions Our analyses suggest that a large majority of the vertebrate tree of life will: (1 be resolved within the next few decades; (2 identify specific data collection strategies that may help to spur future progress; and (3 identify branches of the vertebrate tree of life in need of increased research effort.

  4. Variable velocity in solar external receivers

    One of the major problems in solar external receivers is tube overheating, which accelerates the risk of receiver failure. It can be solved implementing receivers with high number of panels. However, it exponentially increases the pressure drop in the receiver and the parasitic power consumption of the Solar Power Tower (SPT), reducing the global efficiency of the SPT. A new concept of solar external receiver, named variable velocity receiver, is able to adapt their configuration to the different flux density distributions. A set of valves allows splitting in several independent panels those panels in which the wall temperature is over the limit. It increases the velocity of the heat transfer fluid (HTF) and its cooling capacity. This receiver does not only reduce the wall temperature of the tubes, but also simplifies the control of the heliostat field and allows to employ more efficient aiming strategies. In this study, it has been shown that variable velocity receiver presents high advantages with respect to traditional receiver. Nevertheless, more than two divisions per panels are not recommendable, due to the increment of the pressure drop over 70 bars. In the design point (12 h of the Spring Equinox), the use of a variable number of panels between 18 and 36 (two divisions per panel), in a SPT similar to Gemasolar, improves the power capacity of the SPT in 5.7%, with a pressure drop increment of 10 bars. Off-design, when the flux distribution is high and not symmetric (e.g. 10-11 h), the power generated by the variable velocity receiver is 18% higher than the generated by the traditional receiver, at these hours the pressure drop increases almost 20 bars.

  5. Rapid mineralocorticoid receptor trafficking.

    Gekle, M; Bretschneider, M; Meinel, S; Ruhs, S; Grossmann, C

    2014-03-01

    The mineralocorticoid receptor (MR) is a ligand-dependent transcription factor that physiologically regulates water-electrolyte homeostasis and controls blood pressure. The MR can also elicit inflammatory and remodeling processes in the cardiovascular system and the kidneys, which require the presence of additional pathological factors like for example nitrosative stress. However, the underlying molecular mechanism(s) for pathophysiological MR effects remain(s) elusive. The inactive MR is located in the cytosol associated with chaperone molecules including HSP90. After ligand binding, the MR monomer rapidly translocates into the nucleus while still being associated to HSP90 and after dissociation from HSP90 binds to hormone-response-elements called glucocorticoid response elements (GREs) as a dimer. There are indications that rapid MR trafficking is modulated in the presence of high salt, oxidative or nitrosative stress, hypothetically by induction or posttranslational modifications. Additionally, glucocorticoids and the enzyme 11beta hydroxysteroid dehydrogenase may also influence MR activation. Because MR trafficking and its modulation by micro-milieu factors influence MR cellular localization, it is not only relevant for genomic but also for nongenomic MR effects.

    US industry is fighting to maintain its competitive edge in the global market place. Today markets fluctuate rapidly. Companies, to survive, have to be able to respond with quick-to-market, improved, high quality, cost efficient products. The way products are developed and brought to market can be improved and made more efficient through the proper incorporation of emerging technologies. The RRM project was established to leverage the expertise and resources of US private industries and federal agencies to develop, integrate, and deploy new technologies that meet critical needs for effective product realization. The RRM program addressed a needed change in the US Manufacturing infrastructure that will ensure US competitiveness in world market typified by mass customization. This project provided the effort needed to define, develop and establish a customizable infrastructure for rapid response product development design and manufacturing. A major project achievement was the development of a broad-based framework for automating and integrating the product and process design and manufacturing activities involved with machined parts. This was accomplished by coordinating and extending the application of feature-based product modeling, knowledge-based systems, integrated data management, and direct manufacturing technologies in a cooperative integrated computing environment. Key technological advancements include a product model that integrates product and process data in a consistent, minimally redundant manner, an advanced computer-aided engineering environment, knowledge-based software aids for design and process planning, and new production technologies to make products directly from design application software.

    The news media is frequently criticised for failing to support the goals of government health campaigns. But is this necessarily the purpose of the media? We suggest that while the media has an important role in disseminating health messages, it is a mistake to assume that the media should serve the interests of government as it has its own professional ethics, norms, values, structures and roles that extend well beyond the interests of the health sector, and certainly beyond those of the government. While considerable attention has been given to the ways in which uncritical publication of industry perspectives by news media can negatively impact on public understandings of health and health behaviours, we would argue that it is equally important that journalists not become the 'lapdogs' of government interests. Further, we suggest that the interests of public health may be served more by supporting the ongoing existence of an independent media than by seeking to overdetermine its purpose or scope.

  11. Does interest broaden or narrow attentional scope?

    Science.gov (United States)

    Sung, Billy; Yih, Jennifer

    2015-08-10

    Theory proposes that interest is a positive emotion that may either broaden attention to facilitate processing of new information, or narrow attention to preserve engagement with new information. To our knowledge, no research has directly examined the effect of interest on attentional scope. Across four experiments, we show that traits associated with the propensity to experience interest-specifically, trait curiosity and internal boredom proneness-are associated with a narrower scope of attention. We also find that, instead of broadening, interest actually narrows attentional scope in comparison to a neutral state and awe. Challenging the conventional notion that all positive emotions broaden cognition and attention, our findings suggest that specific emotions influence attention in ways that extend beyond a general emotional valence effect.

    Guarato, Francesco; Andrews, Heather; Windmill, James F.; Jackson, Joseph; Gachagan, Anthony

    An ultrasonic localization method for a sonar system equipped with an emitter and two directional receivers and inspired by bat echolocation uses knowledge of the beam pattern of the receivers to estimate target orientation. Rousettus leschenaultii's left ear constitutes the model for the design of the optimal receiver for this sonar system and 3D printing was used to fabricate receiver structures comprising of two truncated cones with an elliptical external perimeter and a parabolic flare rate in the upper part. Measurements show one receiver has a predominant lobe in the same region and with similar attenuation values as the bat ear model. The final sonar system is to be mounted on vehicular and aerial robots which require remote control for motion and sensors for estimation of each robot's location.

  14. High dynamic, low volume GPS receiver

    1983-01-01

    A new GPS receiver concept and design are presented to meet the high dynamic and low volume requirements for range applications in missiles and drones. The receiver has the potential to satisfy all range requirements with one basic receiver, which has significant potential economic benefit over the alternate approach of using a family of receivers, each tailored for specific applications. The main new concept is to use approximate maximum likelihood estimates of pseudo range and range-rate, rather than tracking with carrier phase locked loops and code delay locked loops. Preliminary analysis indicates that receivers accelerating at 50 g or more can track with position errors due to acceleration of approximately 0.2 m/g, or 10 m at 50 g. Implementation is almost entirely digital to meet the low volume requirements.

    Hojat, Mohammadreza; Zuckerman, Marvin

    2008-01-01

    Research on the relationship between personality and specialty interest is important because of its implications in student career counseling and in forecasting future specialty distribution. This study was designed to test the following hypotheses: 1. Students interested in 'surgical' specialties would obtain higher scores on a measure of 'impulsive sensation seeking' and lower scores on a measure of 'neuroticism-anxiety'. 2. Students interested in 'hospital-based' specialties would score lower on a measure of 'sociability' whereas those interested in 'primary care' would score higher on this measure. In addition to these two hypotheses, gender differences on personality were also examined. Study participants were 1,076 students who matriculated at Jefferson Medical College between 2002 to 2006. A short version of the Zuckerman-Kuhlman personality questionnaire (ZKPQ) measuring five personality factors of 'impulsive sensation Seeking', 'neuroticism-anxiety', 'aggression-hostility', 'sociability', and 'activity' was completed by research participants at the beginning of medical school. Students were also asked to note their specialty interests. Multivariate statistical analyses confirmed the first and partially confirmed the second research hypotheses. Results also showed that men scored higher on 'impulsive sensation seeking,' and women outscored men in the 'neuroticism-Anxiety' and 'activity' scales. Findings suggest that information about the personalities of medical students can help to predict their career interests. Implications for career counseling are discussed.

    Social Signal Processing is an emergent area of research that focuses on the analysis of social constructs. Dominance and interest are two of these social constructs. Dominance refers to the level of influence a person has in a conversation. Interest, when referred in terms of group interactions, can be defined as the degree of engagement that the members of a group collectively display during their interaction. In this paper, we argue that only using behavioral motion information, we are able to predict the interest of observers when looking at face-to-face interactions as well as the dominant people. First, we propose a simple set of movement-based features from body, face, and mouth activity in order to define a higher set of interaction indicators. The considered indicators are manually annotated by observers. Based on the opinions obtained, we define an automatic binary dominance detection problem and a multiclass interest quantification problem. Error-Correcting Output Codes framework is used to learn to rank the perceived observer's interest in face-to-face interactions meanwhile Adaboost is used to solve the dominant detection problem. The automatic system shows good correlation between the automatic categorization results and the manual ranking made by the observers in both dominance and interest detection problems.

  17. One editor's views on conflict of interest.

    Rumsey, T S

    1999-09-01

    The purpose of this article is to discuss the importance of recognizing conflict of interest or bias situations in the peer review and publication process of research papers and to identify some important guidelines or policies that help to minimize these situations. Communication of thoughts, ideas, and information is the basis of how we function as a society. Communicating research results requires us to clearly and accurately communicate all aspects of the research process, including the appropriate interpretation of results. A working definition for conflict of interest or bias with regard to publishing research results is that conflict of interest is a situation in which personal benefit (either direct or indirect) takes priority over the clarity and(or) accuracy of reporting research. These situations are ethical issues and can represent either real or assumed situations. It is true that the review and publication process is not perfect; thus, some bias probably is always present and can be brought to the review and publication process by either the author or those responsible for the process. However, conflict of interest or bias that detracts from the objective evaluation of research or the integrity of a scientific journal is inappropriate. Conflict of interest or bias situations can occur at all levels of the review and publication process and should be dealt with on a factual basis. This article describes several situations as examples and several important guidelines that help minimize the occurrence of conflict of interest or bias.

  18. [Potential conflicts of interest in biomedical publications].

    Science.gov (United States)

    García-Vigil, José Luis

    2014-01-01

    In human communication and personal relations, there is the possibility of dissent and have a conflict related to the perception or acceptance of the content of a message. To reach an agreement, it is important that the communication between people is horizontal and bidirectional while the issue is being discussed, in order to bring together the interlocutors' expectations and interests. In the administration of services and goods, friendship and nepotism have been the most frequent forms of potential conflicts of interest. These behaviors arise when a person, like a civil servant or employee, feels influenced by personal considerations when he is doing his work and when he is making decisions. The conflict of perceived interested can be so harmful to the reputation and confidence of an organization, as the real existence of a conflict of interest. In some countries, the law obliges organisms to have codes of ethics that cover these aspects. Thus, it is desirable the incorporation of ethical principles and "moral competences" in the curricula of health professionals. Actually, in medicine and biomedical investigation, conflicts of interest are a condition related to clinicians and researchers, who distort their results and work to obtain personal or financial benefits. In the generation and transmission of knowledge, the circumstances determine if a conflict of interest exists, not the methodology, either the results of the investigation, not even the technology used on their diffusion.

  20. Overcoming the Challenges of BeiDou Receiver Implementation

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available Global Navigation Satellite System (GNSS-based positioning is experiencing rapid changes. The existing GPS and the GLONASS systems are being modernized to better serve the current challenging applications under harsh signal conditions. These modernizations include increasing the number of transmission frequencies and changes to the signal components. In addition, the Chinese BeiDou Navigation Satellite system (BDS and the European Galileo are currently under development for global operation. Therefore, in view of these new upcoming systems the research and development of GNSS receivers has been experiencing a new upsurge. In this article, the authors discuss the main functionalities of a GNSS receiver in view of BDS. While describing the main functionalities of a software-defined BeiDou receiver, the authors also highlight the similarities and differences between the signal characteristics of the BeiDou B1 open service signal and the legacy GPS L1 C/A signal, as in general they both exhibit similar characteristics. In addition, the authors implement a novel acquisition technique for long coherent integration in the presence of NH code modulation in BeiDou D1 signal. Furthermore, a simple phase-preserved coherent integration based acquisition scheme is implemented for BeiDou GEO satellite acquisition. Apart from the above BeiDou-specific implementations, a novel Carrier-to-Noise-density ratio estimation technique is also implemented in the software receiver, which does not necessarily require bit synchronization prior to estimation. Finally, the authors present a BeiDou-only position fix with the implemented software-defined BeiDou receiver considering all three satellite constellations from BDS. In addition, a true multi-GNSS position fix with GPS and BDS systems is also presented while comparing their performances for a static stand-alone code phase-based positioning.

  1. Why Having a (Nonfinancial) Interest Is Not a Conflict of Interest

    OpenAIRE

    Bero, Lisa A.; Grundy, Quinn

    2016-01-01

    A current debate about conflicts of interest related to biomedical research is to question whether the focus on financial conflicts of interest overshadows "nonfinancial" interests that could put scientific judgment at equal or greater risk of bias. There is substantial evidence that financial conflicts of interest such as commercial sponsorship of research and investigators lead to systematic biases in scientific research at all stages of the research process. Conflation of "conflicts of int...

  4. Financial conflicts of interest in science.

    Science.gov (United States)

    Sax, Joanna K

    2012-01-01

    This Article proposes a new direction for addressing financial conflicts of interest, which plague biomedical research and threaten scientific integrity. This Article descriptively states the controversy surrounding financial conflicts of interest by explaining how these conflicts arise and the damage that can be created as a result. By describing the scientific process, the Article explains that changes to the academic environment may allow the public-private interaction to proceed, without creating the problems associated with financial conflicts of interest. Financial conflicts of interest are created when the profit-seeking motive of a private funding source unduly influences an academic scientist's primary responsibilities. The problem with financial conflicts of interest has grown since the passage of the Bayh-Dole Act in 1980. The cornerstone of current policies to address financial conflicts of interest is disclosure, which is inadequate and unsatisfying. The analysis herein changes the trajectory of current approaches in this area by proposing that an analysis of the underlying environment and behavior leading to conflicts of interest must be considered. This Article proposes the use of behavioral economics to craft a policy that effectively addresses conflicts of interest. To this end, this Article applies research from the field of psychology to understand both the environment of academic scientists as well as to begin to understand how academic scientists make decisions. Drawing on psychology literature, this article proposes that academic scientists may experience cognitive dissonance when faced with a situation in which a conflict of interest may arise. This helps to understand why an academic scientist may make a decision that creates a conflict of interest. In addition, this Article utilizes the results of an empirical study conducted by myself and a colleague. In this study, we asked faculty at five medical schools to respond to an anonymous survey

    A survey is given on the progress of fast chemical separation procedures during the last few years. Fast, discontinuous separation techniques are illustrated by a procedure for niobium. The use of such techniques for the chemical characterization of the heaviest known elements is described. Other rapid separation methods from aqueous solutions are summarized. The application of the high speed liquid chromatography to the separation of chemically similar elements is outlined. The use of the gas jet recoil transport method for nuclear reaction products and its combination with a continuous solvent extraction technique and with a thermochromatographic separation is presented. Different separation methods in the gas phase are briefly discussed and the attachment of a thermochromatographic technique to an on-line mass separator is shown. (45 refs).

The compensation algorithm is enhanced by considering the deviations between the stamped and designed components. The FEM model validation has been performe...

  9. Fundamentals of GPS Receivers A Hardware Approach

    CERN Document Server

    Doberstein, Dan

    2012-01-01

    While much of the current literature on GPS receivers is aimed at those intimately familiar with their workings, this volume summarizes the basic principles using as little mathematics as possible, and details the necessary specifications and circuits for constructing a GPS receiver that is accurate to within 300 meters. Dedicated sections deal with the features of the GPS signal and its data stream, the details of the receiver (using a hybrid design as exemplar), and more advanced receivers and topics including time and frequency measurements. Later segments discuss the Zarlink GPS receiver chip set, as well as providing a thorough examination of the TurboRogue receiver, one of the most accurate yet made. Guiding the reader through the concepts and circuitry, from the antenna to the solution of user position, the book’s deployment of a hybrid receiver as a basis for discussion allows for extrapolation of the core ideas to more complex, and more accurate designs. Digital methods are used, but any analogue c...

  10. To Internationalize Rapidly from Inception: Crowdsource

    Directory of Open Access Journals (Sweden)

    Nirosh Kannangara

    2012-10-01

    Full Text Available Technology entrepreneurs continuously search for tools to accelerate the internationalization of their startups. For the purpose of internationalizing rapidly from inception, we propose that technology startups use crowdsourcing to internalize the tacit knowledge embodied in members of a crowd distributed across various geographies. For example, a technology startup can outsource to a large crowd the definition of a customer problem that occurs across various geographies, the development of the best solution to the problem, and the identification of attractive business expansion opportunities. In this article, we analyze how three small firms use crowdsourcing, discuss the benefits of crowdsourcing, and offer six recommendations to technology entrepreneurs interested in using crowdsourcing to rapidly internationalize their startups from inception.

    Science.gov (United States)

    Kupferman, Judy; Arnon, Shlomi

    2018-01-01

    Vortex light beams can provide a tremendous alphabet for encoding information. We derive a symbol decoding algorithm for a direct detection matrix detector vortex beam receiver using Laguerre Gauss (LG) modes, and develop a mathematical model of symbol error rate (SER) for this receiver. We compare SER as a function of signal to noise ratio (SNR) for our algorithm and for the Pearson correlation algorithm. To our knowledge, this is the first comprehensive treatment of a decoding algorithm of a matrix detector for an LG receiver.

  13. Exploiting Redundancy in an OFDM SDR Receiver

    Directory of Open Access Journals (Sweden)

    Tomas Palenik

    2009-01-01

    Full Text Available Common OFDM system contains redundancy necessary to mitigate interblock interference and allows computationally effective single-tap frequency domain equalization in receiver. Assuming the system implements an outer error correcting code and channel state information is available in the receiver, we show that it is possible to understand the cyclic prefix insertion as a weak inner ECC encoding and exploit the introduced redundancy to slightly improve error performance of such a system. In this paper, an easy way to implement modification to an existing SDR OFDM receiver is presented. This modification enables the utilization of prefix redundancy, while preserving full compatibility with existing OFDM-based communication standards.

    A Sandia project currently uses an outdated Magnavox 6400 Global Positioning System (GPS) receiver as the core of its navigation system. The goal of this study was to analyze the performance of the current GPS receiver compared to newer, less expensive models and to make recommendations on how to improve the performance of the overall navigation system. This paper discusses the test methodology used to experimentally analyze the performance of different GPS receivers, the test results, and recommendations on how an upgrade should proceed. Appendices contain detailed information regarding the raw data, test hardware, and test software.

    1990-01-01

    This study replicated another by Hanson and Chater (1983) that investigated the relationship between interest in management roles and personality, demographic, and career background characteristics of female nurses. For the present study, 128 sophomore, senior, and master's degree students were asked to participate and a self-selected convenience sample of 69 was obtained. Three instruments were used: The Vocational Preference Inventory (VPI), to measure personality traits; a demographic data questionnaire, to measure demographic variables; and the Strong-Campbell Interest Inventory, to measure managerial interests. The total sample of nurses exhibited an artistic-social-intellectual profile. The subhypothesis that nurses of different education levels would exhibit different personality profiles was supported. Analysis of VPI scores demonstrated a statistically significant association between higher educational levels of nurses and higher acquiescence scores, (F = 5.1729 with a significance level of 0.0082). Analysis of variance of Vocational Preference Inventory scale scores showed a statistically significant association between nurses interested in management and higher scores on the enterprising attribute (F = 5.7753 with a significance level of 0.0266). No significant difference was found between management and nonmanagement interest groups in demographic and career characteristics. The findings of this study contribute more insight and knowledge about nurses who select management and administrative roles.

  17. Violence on television. Unpleasant, interesting or morbid?

    Directory of Open Access Journals (Sweden)

    C Fernández Villanueva

    2013-10-01

    Full Text Available Introduction: Many research studies have contributed to the study of the effects of violence on TV, but very few of them have paid attention to the reasons why violence arouses interest or rejection among viewers. The objective of this article is to analyse the discourses, arguments and moral criteria used by the audience to justify their interest or disinterest in TV violence. Methods: The study is based on 16 focus groups carried out in Madrid and segmented by sex, age and education level. Results: The study indicates that audience’s attitudes towards representations of violence on TV range from rejection to morbid interest, including intolerance, lack of interest and self-protection. These attitudes vary depending on whether the representations of violence are real or fictional. Conclusions: The results contradict the popular idea that TV audiences are generally attracted to the TV representations of violence and indicate that this “emotional interest” in violence is actually accompanied by an interest in learning about this phenomenon and developing ethical reflections.

    2016-01-01

    Considering the reported lack of interest in the STEM-domain and the consequential difficulties in recruiting talented and interested young academics, the development of effective enrichment measures is indispensable. This requires a precise picture of students' interests. The paper presents an approach to characterize interest profiles in explicitly science-related activities. Adapting Holland's RIASEC-model, an instrument was developed and tested which allows the description of interest in activities along Holland's dimensions (and a seventh dimension networking) within the confined science domain. The findings of a study with N = 247 students (age cohorts 12-19 years) uncovered interest differences for the environments school, enrichment, and (prospective) vocation. The mutual importance of the performed activity and the environment the activity is performed in is confirmed by a cross-classified model. Contrasting different subgroups revealed multiple results, e.g., girls showed more interest in artistic and social activities within the science domain. High achieving students showed more interest in science-related activities in all dimensions. In conclusion, using our adapted model, students' interest structure can be described in a differentiated manner. This could lay the foundation for further analyses of students' interest profiles and thereby contribute to future development of effective and congruent enrichment measures, thus enhancing interest in science.

  20. Syskill & Webert: Identifying interesting web sites

    Energy Technology Data Exchange (ETDEWEB)

    Pazzani, M.; Muramatsu, J.; Billsus, D. [Univ. of California, Irvine, CA (United States)

    1996-12-31

    We describe Syskill & Webert, a software agent that learns to rate pages on the World Wide Web (WWW), deciding what pages might interest a user. The user rates explored pages on a three point scale, and Syskill & Webert learns a user profile by analyzing the information on each page. The user profile can be used in two ways. First, it can be used to suggest which links a user would be interested in exploring. Second, it can be used to construct a LYCOS query to find pages that would interest a user. We compare six different algorithms from machine learning and information retrieval on this task. We find that the naive Bayesian classifier offers several advantages over other learning algorithms on this task. Furthermore, we find that an initial portion of a web page is sufficient for making predictions on its interestingness substantially reducing the amount of network transmission required to make predictions.

  1. Enhancing Students’ Interest through Mathematics Learning

    Science.gov (United States)

    Azmidar, A.; Darhim, D.; Dahlan, J. A.

    2017-09-01

    A number of previous researchers indicated that students’ mathematics interest still low because most of them have perceived that mathematics is very difficult, boring, not very practical, and have many abstract theorems that were very hard to understand. Another cause is the teaching and learning process used, which is mechanistic without considering students’ needs. Learning is more known as the process of transferring the knowledge to the students. Let students construct their own knowledge with the physical and mental reflection that is done by activity in the new knowledge. This article is literature study. The purpose of this article is to examine the Concrete-Pictorial-Abstract approach in theoretically to improve students’ mathematics interest. The conclusion of this literature study is the Concrete-Pictorial-Abstract approach can be used as an alternative to improve students’ mathematics interest.

    Several major conceptual design studies of solar central receiver systems and components were completed in the last year. The results of these studies were used to compare the projected cost of electric power generation using central receiver systems with that of more conventional power generation. The cost estimate for a molten salt central receiver system is given. Levelized busbar energy cost is shown as a function of annual capacity factor indicating the fraction of the cost due to each of the subsystems. The estimated levelized busbar energy cost for a central receiver (70 to 90 mills per kilowatt hour) is compared with the levelized busbar energy cost for a new coal fired Rankine cycle plant. Sensitivities to the initial cost of coal and the delta fuel escalation are shown.

    This is an attempt to develop a biotelemetry receiver using digital signal processing technology and techniques. The receiver developed in this work is based on recovering signals that have been encoded using either Pulse Position Modulation (PPM) or Pulse Code Modulation (PCM) technique. A prototype has been developed using state-of-the-art digital signal processing technology. A Printed Circuit Board (PCB) is being developed based on the technique and technology described here. This board is intended to be used in the UCSF Fetal Monitoring system developed at NASA. The board is capable of handling a variety of PPM and PCM signals encoding signals such as ECG, temperature, and pressure. A signal processing program has also been developed to analyze the received ECG signal to determine heart rate. This system provides a base for using digital signal processing in biotelemetry receivers and other similar applications.

    The Validation Demonstration establishes that the high dynamic Global Positioning System (GPS) receiver concept developed at JPL meets the dynamic tracking requirements for range instrumentation of missiles and drones. It was demonstrated that the receiver can track the pseudorange and pseudorange rate of vehicles with acceleration in excess of 100 g and jerk in excess of 100 g/s, dynamics ten times more severe than specified for conventional High Dynamic GPS receivers. These results and analytic extensions to a complete system configuration establish that all range instrumentation requirements can be met. The receiver can be implemented in the 100 cu in volume required by all missiles and drones, and is ideally suited for transdigitizer or translator applications.

    Walcott, Brian P; Sheth, Sameer A; Nahed, Brian V; Coumans, Jean-Valery

    2012-01-01

    Medical studies are more likely to report favorable findings when a conflict of interest is declared. We aim to quantify and determine the effect of author disclosure of conflict of interest on scientific reporting. Abstracts from an international spine research meeting (North American Spine Society 2010) were selected that specifically evaluated a device, biologic, or proprietary procedure. They were then made anonymous to reviewers. An item of interest was established in each of the abstracts in order to standardize evaluation. Next, three blinded reviewers independently rated the abstracts as favorable, neutral, or unfavorable with regard to the item of interest. Additionally, the blinded reviewers attempted to predict whether a related disclosure was made. The meeting disclosure index was used to tabulate the minimum US dollar value attributable to disclosures. Of the 344 total abstracts, 76 met inclusion criteria. In 79%, a related conflict of interest was reported. The amount of the disclosure was incompletely reported in 30% of cases. Where available, it averaged a cumulative minimum of $219,634 USD per abstract. The results of the abstracts were judged to be favorable, neutral, and unfavorable in 63%, 32% and 5% of abstracts, respectively. There was no correlation between the presence of a related disclosure and the findings of the studies (p = 0.81), although interpretation of this is limited by a small sample size and an overall apparent bias to report favorable studies. Additionally, the blinded reviewers were unable to predict whether a related disclosure was made (p = 0.40). No association existed between the presence of a related disclosure and the results of the studies. While the actual compliance with reporting a potential conflict of interest is unable to be determined, the value amount related to the disclosures made was inadequately reported according to meeting guidelines.

    Financial relationships in academic research can create institutional conflicts of interest (COIs) because the financial interests of the institution or institutional officials may inappropriately influence decision-making. Strategies for dealing with institutional COIs include establishing institutional COI committees that involve the board of trustees in conflict review and management, developing policies that shield institutional decisions from inappropriate influences, and establishing private foundations that are independent of the institution to own stock and intellectual property and to provide capital to start-up companies.

    2007-01-01

    The use of rapid response teams is a relatively new approach for decreasing or eliminating codes in acute care hospitals. Based on the principles of a code team for cardiac and/or respiratory arrest in non-critical care units, the rapid response teams have specially trained nursing, respiratory, and medical personnel to respond to calls from general care units to assess and manage decompensating or rapidly changing patients before their conditions escalate to a full code situation. This article describes the processes used to develop a rapid response team, clinical indicators for triggering a rapid response team call, topics addressed in an educational program for the rapid response team members, and methods for evaluating effectiveness of the rapid response team.

  19. Rapid temporal recalibration to visuo-tactile stimuli.

    Science.gov (United States)

    Lange, Joachim; Kapala, Katharina; Krause, Holger; Baumgarten, Thomas J; Schnitzler, Alfons

    2017-11-15

    For a comprehensive understanding of the environment, the brain must constantly decide whether the incoming information originates from the same source and needs to be integrated into a coherent percept. This integration process is believed to be mediated by temporal integration windows. If presented with temporally asynchronous stimuli for a few minutes, the brain adapts to this new temporal relation by recalibrating the temporal integration windows. Such recalibration can occur even more rapidly after exposure to just a single trial of asynchronous stimulation. While rapid recalibration has been demonstrated for audio-visual stimuli, evidence for rapid recalibration of visuo-tactile stimuli is lacking. Here, we investigated rapid recalibration in the visuo-tactile domain. Subjects received visual and tactile stimuli with different stimulus onset asynchronies (SOA) and were asked to report whether the visuo-tactile stimuli were presented simultaneously. Our results demonstrate visuo-tactile rapid recalibration by revealing that subjects' simultaneity reports were modulated by the temporal order of stimulation in the preceding trial. This rapid recalibration effect, however, was only significant if the SOA in the preceding trial was smaller than 100 ms, while rapid recalibration could not be demonstrated for SOAs larger than 100 ms. Since rapid recalibration in the audio-visual domain has been demonstrated for SOAs larger than 100 ms, we propose that visuo-tactile recalibration works at shorter SOAs, and thus faster time scales than audio-visual rapid recalibration.

    Full Text Available With the rapid development of the tourist hotel, the hotel has many problems in the protection of employee rights and interests. To enhance the importance that hotel managers attach to the protection of em-ployee’s rights and interests, and strengthen the hotel employees’ consciousness in rights protection, this paper regards the China’s tourist hotel employees as research objects, discusses the problems and causes in the process of protecting the tourist hotel employee rights and interests, and proposes solutions with the basic idea of “dis-covering, analyzing and solving problems”.

  1. Problems of rapid growth.

    Kim, T D

    South Korea's export-oriented development strategy has achieved a remarkable growth record, but it has also brought 2 different problems: 1) since the country's exports accounted for about 1% of total world export volume, the 1st world has become fearful about Korea's aggressive export drive; and 2) the fact that exports account for over 30% of its total gross national product (GNP) exposes the vulnerability of South Korea's economy itself. South Korea continues to be a poor nation, although it is rated as 1 of the most rapidly growing middle income economies. A World Bank 1978 report shows Korea to be 28th of 58 middle income countries in terms of per capita GNP in 1976. Of 11 newly industrializing countries (NIC), 5 in the European continent are more advanced than the others. A recent emphasis on the basic human needs approach has tended to downgrade the concept of GNP. Korea has only an abundant labor force and is without any natural resources. Consequently, Korea utilized an export-oriented development strategy. Oil requirements are met with imports, and almost all raw materials to be processed into exportable products must be imported. To pay import bills Korea must export and earn foreign exchange. It must be emphasized that foreign trade must always be 2-way traffic. In order to export more to middle income countries like Korea, the countries of the 1st world need to ease their protectionist measures against imports from developing countries.

    Method and system for rapid and accurate determination of each of a sequence of unknown polymer components, such as nucleic acid components. A self-assembling monolayer of a selected substance is optionally provided on an interior surface of a pipette tip, and the interior surface is immersed in a selected liquid. A selected electrical field is impressed in a longitudinal direction, or in a transverse direction, in the tip region, a polymer sequence is passed through the tip region, and a change in an electrical current signal is measured as each polymer component passes through the tip region. Each of the measured changes in electrical current signals is compared with a database of reference electrical change signals, with each reference signal corresponding to an identified polymer component, to identify the unknown polymer component with a reference polymer component. The nanopore preferably has a pore inner diameter of no more than about 40 nm and is prepared by heating and pulling a very small section of a glass tubing.

  3. Using Situational Interest to Enhance Individual Interest and Science-Related Behaviours

    Palmer, David; Dixon, Jeanette; Archer, Jennifer

    2017-08-01

    Situational interest is a relatively transient reaction to highly stimulating factors in the immediate environment, whereas individual interest is a relatively long-term preference for a particular subject or activity. It has been proposed that regular experiences of situational interest in a subject may eventually lead to the development of individual interest in that subject. Importantly, this should also result in an increase in behaviours related to that domain. For example, a student who develops an individual interest in science would be expected to spend more time on science-related activities such as reading about science, talking with other people about science, or watching science shows on TV. However, the extent to which this does happen has not yet been established. The purposes of this study were to find out whether regular experiences of situational interest in science classes can enhance individual interest in science and whether there is an associated increase in science-related activities. The participants were primary teacher education students who were enrolled in a semester-length science course. Data were collected using a survey, an interest inventory, open-ended questionnaires and interviews. It was found that regular experiences of situational interest during the course were associated with positive changes in individual interest in science and increased participation in science-related activities. These changes remained relatively stable over a delay period of 10 months after the end of the course.

  11. Teachers’ knowledge for teaching compound interest

    Directory of Open Access Journals (Sweden)

    Craig Pournara

    2013-09-01

    Full Text Available There is increasing acknowledgement that teachers’ knowledge for teaching mathematics is multifaceted and topic specific. Given the paucity of research on the teaching and learning of financial mathematics in general, little can be known about teachers’ knowledge for teaching compound interest. However, since financial mathematics is a component of the school curriculum in South Africa, and an important element of financial literacy more broadly, attention needs to be given to knowledge for teaching financial mathematics, and compound interest in particular. Drawing from a larger study in which the author taught a financial mathematics course to pre-service secondary mathematics teachers, a theoretical elaboration is provided of the underlying mathematics of compound interest, and connections with the world of banking. Based on findings from the study, two key student errors are identified: the over-generalisation of linear thinking in multiplicative scenarios, and the over-generalisation of reversible operations in percentage-change scenarios. Taken together, teachers’ knowledge of relevant mathematics, of the banking context and of learners’ conceptions will contribute to building a knowledge-base for teachers’ knowledge for teaching compound interest.

    González, María de la O; Jareño, Francisco; Skinner, Frank S

    2016-01-01

    We examine investor behavior under interest and inflation risk in different scenarios. To that end, we analyze the relation between stock returns and unexpected changes in nominal and real interest rates and inflation for the US stock market. This relation is examined in detail by breaking the results down from the US stock market level to sector, sub-sector, and to individual industries as the ability of different industries to absorb unexpected changes in interest rates and inflation can vary by industry and by contraction and expansion sub-periods. While most significant relations are conventionally negative, some are consistently positive. This suggests some relevant implications on investor behavior. Thus, investments in industries with this positive relation can form a safe haven from unexpected changes in real and nominal interest rates. Gold has an insignificant beta during recessionary conditions hinting that Gold can be a safe haven during recessions. However, Gold also has a consistent negative relation to unexpected changes in inflation thereby damaging the claim that Gold is a hedge against inflation.

  19. Collaborative Filtering Recommendation on Users' Interest Sequences.

    Directory of Open Access Journals (Sweden)

    Weijie Cheng

    Full Text Available As an important factor for improving recommendations, time information has been introduced to model users' dynamic preferences in many papers. However, the sequence of users' behaviour is rarely studied in recommender systems. Due to the users' unique behavior evolution patterns and personalized interest transitions among items, users' similarity in sequential dimension should be introduced to further distinguish users' preferences and interests. In this paper, we propose a new collaborative filtering recommendation method based on users' interest sequences (IS that rank users' ratings or other online behaviors according to the timestamps when they occurred. This method extracts the semantics hidden in the interest sequences by the length of users' longest common sub-IS (LCSIS and the count of users' total common sub-IS (ACSIS. Then, these semantics are utilized to obtain users' IS-based similarities and, further, to refine the similarities acquired from traditional collaborative filtering approaches. With these updated similarities, transition characteristics and dynamic evolution patterns of users' preferences are considered. Our new proposed method was compared with state-of-the-art time-aware collaborative filtering algorithms on datasets MovieLens, Flixster and Ciao. The experimental results validate that the proposed recommendation method is effective and outperforms several existing algorithms in the accuracy of rating prediction.

    Full Text Available In this paper I will discuss Milton Friedman’s thesis that the social responsibilityof business is to maximize the shareholders’ profit. I examine the underlyingassumption of self-interest and argue, contrary to the neoliberal thesis ofderegulation, that the profit motive must be constrained by strong state regulations.Furthermore it facilitates keeping the division between business andgovernment intact. The financial crisis shows that the emphasis on a profitmotive without the external constraints of tight regulations has serious implicationsfor the trustworthiness of business. In the latter part of the paper I willdiscuss trust in relation to self-interest. The overemphasis on self-interest isparticularly unfortunate in connection with business, and not least the financialsector, as this institution is grounded in trust, without which it cannot survive.Seen from this angle, it can be claimed that a business model, celebratingprimarily self-interest, profit-motive and deregulation, is not going to be sustainablein the long run.http://dx.doi.org/10.5324/eip.v3i2.1719

    Jox, R J

    2011-10-01

    Treatment decisions for patients in the vegetative state often have to be based on the patient's best interests, if the patient's will is not known. Physicians are, however, highly uncertain what kind of treatment is in such a difficult situation the patient's best interests. This article presents new insights from neuroscience and shows how treatment decision making should proceed to reach an ethically justified decision. Pivotal elements are a careful diagnosis using validated behavioural scales, an informed judgment about the existence of awareness and sentience, and an early prognostic assessment. As new imaging techniques and treatment options are not yet clinical standard due to low evidence, the best interests have to be judged in the context of uncertainty. The leading question should be whether the preferred treatment goal can be achieved with a realistic probability and a justifiable benefit-harm-ratio. This has to be judged for the individual patient, considering his personality and communicating with the family members. There cannot be a general answer to the question of best interests in the vegetative state, but only an individual answer in shared responsibility and based on the particular features of a special case. © Georg Thieme Verlag KG Stuttgart · New York.

    Fusion promises to provide clean and safe energy, and a considerable amount of research effort is underway to turn this aspiration intoreality. This work focuses on a building block for analyzing data produced from the simulation of microturbulence in magnetic confinementfusion devices: the task of efficiently extracting regions of interest. Like many other simulations where a large amount of data are produced,the careful study of ``interesting'' parts of the data is critical to gain understanding. In this paper, we present an efficient approach forfinding these regions of interest. Our approach takes full advantage of the underlying mesh structure in magnetic coordinates to produce acompact representation of the mesh points inside the regions and an efficient connected component labeling algorithm for constructingregions from points. This approach scales linearly with the surface area of the regions of interest instead of the volume as shown with bothcomputational complexity analysis and experimental measurements. Furthermore, this new approach is 100s of times faster than a recentlypublished method based on Cartesian coordinates.

    2014-03-01

    The Accreditation Council for Graduate Medical Education (ACGME) has established communication as a core competency for physicians in training. However, data suggest that most pediatric residents perceive inadequate training in the delivery of bad news and the majority of former trainees in pediatric oncology received no formal training in the delivery of bad news during fellowship. The study examines communication training in ACGME accredited US pediatric hematology-oncology (PHO) fellowship programs. An online survey was distributed to 315 PHO fellows in training via the American Society of Pediatric Hematology/Oncology (ASPHO) fellow email registry. Each fellow received an initial request to participate and 2 reminders, while participation was encouraged through a random incentive drawing. One hundred and ten fellows (35%) responded. Eighty percent of respondents perceived communication training to be important to fellow education, however only 32% reported receiving communication training (other than direct observation). The most common reported teaching method of fellowship communication training was formal lecture (42%). Twenty-three percent of respondents reported neither communication training nor frequent feedback on their communication skills from faculty observation. This same group was the least satisfied with their programs' approach to teaching communication (P training in PHO fellowships despite ACGME requirements and fellows' interest in this training. Didactic learning remains the most frequently described training method, yet educational theory identifies the limitation of didactic lectures alone. Communication training employing novel teaching methods and emphasizing communication challenges identified by fellows should be developed and evaluated. © 2013 Wiley Periodicals, Inc.

    A digital coherent receiver technique for an onboard receiver for use in a future space optical communication system is investigated. Digital coherent technologies comprising coherent detection and digital signal processing are confirmed to possibly increase the signal speed, improve the receiver sensitivity, and extend tolerance for the Doppler frequency shift. As a facet of expandability, the concept of a multichannel-rate receiver using a digital coherent technique is introduced. Experimental results using 2.5 Gbps DBPSK signal light demodulation are presented together with future issues involved in implementation. This study confirms that the digital coherent receiver has higher expandability than other detection techniques.

  18. Rapid mixing kinetic techniques.

    Science.gov (United States)

    Martin, Stephen R; Schilstra, Maria J

    2013-01-01

    Almost all of the elementary steps in a biochemical reaction scheme are either unimolecular or bimolecular processes that frequently occur on sub-second, often sub-millisecond, time scales. The traditional approach in kinetic studies is to mix two or more reagents and monitor the changes in concentrations with time. Conventional spectrophotometers cannot generally be used to study reactions that are complete within less than about 20 s, as it takes that amount of time to manually mix the reagents and activate the instrument. Rapid mixing techniques, which generally achieve mixing in less than 2 ms, overcome this limitation. This chapter is concerned with the use of these techniques in the study of reactions which reach equilibrium; the application of these methods to the study of enzyme kinetics is described in several excellent texts (Cornish-Bowden, Fundamentals of enzyme kinetics. Portland Press, 1995; Gutfreund, Kinetics for the life sciences. Receptors, transmitters and catalysis. Cambridge University Press, 1995).There are various ways to monitor changes in concentration of reactants, intermediates and products after mixing, but the most common way is to use changes in optical signals (absorbance or fluorescence) which often accompany reactions. Although absorbance can sometimes be used, fluorescence is often preferred because of its greater sensitivity, particularly in monitoring conformational changes. Such methods are continuous with good time resolution but they seldom permit the direct determination of the concentrations of individual species. Alternatively, samples may be taken from the reaction volume, mixed with a chemical quenching agent to stop the reaction, and their contents assessed by techniques such as HPLC. These methods can directly determine the concentrations of different species, but are discontinuous and have a limited time resolution.

    2004-09-01

    A single rate multicast congestion control for streaming media applications called Binomial congestion control At Receivers for Multicast (BARM) is proposed. Combining aspects of window-based and rate-based congestion control, the protocol shifts most of the congestion control mechanisms to multicast receivers. The main features of BARM are as follows. (1) The protocol adopts binomial algorithm (k=l=0.5, α=0.28, β=0.2 for our implementation) to adjust congestion window, which not only provides TCP-friendliness but decreases abrupt rate fluctuations, making it suitable for real time streaming media multicast applications. (2) The binomial algorithm is executed at the receivers instead of at the sender; to do this, a congestion window is maintained and updated separately by each receiver. Hence the protocol not only has a better scalability but reduces the burden of the sender significantly and is suitable to Client/Server model. (3) The congestion window is converted to the expected receiving rate which is then fed back to the sender if permitted. Compared to window feedback scheme, rate feedback scheme is simpler and increases the scalability. (4) The representative approach is used to suppress the feedback implosion. Simulations results indicate that BARM shows good fairness, TCP-friendliness, smoothness, scalability, and acceptable responsiveness.

  1. Chiral Receiving Antenna With Low Backscattering Levels

    CERN Document Server

    Karilainen, Antti O

    2011-01-01

    Receiving antennas absorb power from incident waves, but they also re-radiate some power into surrounding space. If a receiving antenna is to be used as a sensor which should not disturb the object under study, it should scatter as little power as possible in the receiving direction. We propose to use a chiral element composed of two orthogonal chiral particles as a low-scattering sensor.The element can transmit and receive circular polarization in all directions with the Huygens' pattern. We derive the vector effective length for the antenna using the small dipole approximation for the chiral particles. We observe that the element does not backscatter, regardless of the polarization, when the incidence direction is normal to the plane of the particles. Scattered fields, scattered axial ratio, and the scattering cross section are presented. We show that the zero-backscattering property holds also for the antenna element when it is capable to receive all the available power with conjugate loading. The approxim...

Patients who had received E.C.T. were compared with those who did not receive tis treatment. The results showed that a high proportion (21%) had received E.C.T. In comparison with patients not receiving E.C.T., E.C.T. recipients were significantly older, more often female, had greater number of previous admissions, greater incidence of violent behaviour, and longer stays in hospital. E.C.T. patients did not differ from others on social class, education, and marital status, nor was E.C.T. prescribed more often to patients who had demonstrated suicidal behaviour, even if they had a diagnosis of depression. E.C.T. and non E.C.T. patients received an equal number of psychotropic drugs.

    manufacturing. The cost and design goals for the project were met with this task, but the most interesting results had to do with defining the failure modes and looking at a “shakedown analysis” of the combined creep-fatigue failure. A separate task also looked at improving the absorber coatings on the receiver tubes that would improve the efficiency of the receiver. Significant progress was made on developing a novel paint with a high absorptivity that was on par with the current Pyromark, but shows additional potential to be optimized further. Although the coating did not meet the emissivity goals, preliminary testing the new paint shows potential to be much more durable, and potential to improve the receiver efficiency through a higher average absorptivity over the lifetime. Additional coatings were also designed and modeled results meet the project goals, but were not tested. Testing for low cycle fatigue of the full length receiver tubes was designed and constructed, but is still currently undergoing testing. A novel small heliostat was developed through an extensive brainstorming and down select. The concept was then detailed further with inputs from component testing and eventually a full prototype was built and tested. This task met or exceeded the accuracy and structure goals and also beat the cost goal. This provides a significant solar field costs savings for Abengoa that will be developed further to be used in future commercial plants. Ultimately the $0.09/kWhe (real 2009 $) and 6,400 hours goals of the project were met.

    1976-09-01

    A model for a windowed, high-temperature cavity receiver of the heated-air type is developed and used to evaluate the greenhouse effect as a method for obtaining high receiver operating efficiencies. The effects on receiver efficiency of varying the window cutoff wavelength, the amount of absorption in the window pass-band, the cavity operating temperature, and the number of windows are determined. Single windowed cavities are found to offer theoretical efficiencies comparable to windowless ones, while multiple windowed units are found to suffer from low operating efficiencies due to losses resulting from reflections at each window/air interface. A ''first order'' examination is made of the feasibility of air cooling the window to assure its survival. This appears possible if a proper combination of cooling technique and window material characteristics is selected.

    Full Text Available To solve various problems of the Internet, content centric networking (CCN, one of information centric networking architectures (ICN, provides both an in-network content caching scheme and a built-in content verification scheme. However, a user is still asked to generate many request messages when retrieving fragmented content through CCN. This model can seriously increase the amount of network traffic. Furthermore, when receiving content, a user is asked to verify the received content before using it. This verification process can cause a serious service delay. To improve such inefficiencies, this paper proposes a transmission process to handle request messages at one time. Also, it suggests an efficient content verification method using both hash chains and Merkel-hash tree.

    The laboratory, as a diagnostic department in the hospital, plays an important role in the treatment and prevention of diseases. Paying attention to patients' preferences for communication of test results may provide a better and more responsive system for delivering these results. This study aimed to identify patient preferences regarding receiving their laboratory test results electronically and to identify the reasons behind their choice. Descriptive-analytical study. This study was carried out in 2015 with 200 patients who had access to the internet and had been referred at least once previously to the hospital laboratory department to receive their test results. Data were collected through an expert-validated questionnaire, and its reliability was confirmed by test-retest (P = .8). Data were analyzed using χ2 and marginal independence SPSS and R software. Ninety-eight percent of participants preferred to be notified by short message service when their test results were ready. All participants preferred to receive their test results online, and 82.5% (n = 165) preferred to receive both normal and abnormal test results this way. The main reason for receiving results online was time savings, which was reported by 77% of participants, followed by lowering the chance of missing the results (31%). About 40% of participants thought e-mail notification was more secure than accessing the results through a hospital website. Findings showed that although patients wanted to benefit from online services for receiving their test results, they were concerned about confidentiality and security. Before using online technologies, security measures necessary to protect patient privacy and to gain the trust of patients should be defined.

    An avalanche photodiode (APD) array for ground-based optical communications receivers is investigated for the reception of optical signals through the turbulent atmosphere. Kolmogorov phase screen simulations are used to generate realistic spatial distributions of the received optical field. It is shown that use of an APD array for pulse-position modulation detection can improve performance by up to 4 dB over single APD detection in the presence of turbulence, but that photon-counting detector arrays yield even greater gains.

  10. Rapid Active Sampling Package

    2010-01-01

    A field-deployable, battery-powered Rapid Active Sampling Package (RASP), originally designed for sampling strong materials during lunar and planetary missions, shows strong utility for terrestrial geological use. The technology is proving to be simple and effective for sampling and processing materials of strength. Although this originally was intended for planetary and lunar applications, the RASP is very useful as a powered hand tool for geologists and the mining industry to quickly sample and process rocks in the field on Earth. The RASP allows geologists to surgically acquire samples of rock for later laboratory analysis. This tool, roughly the size of a wrench, allows the user to cut away swaths of weathering rinds, revealing pristine rock surfaces for observation and subsequent sampling with the same tool. RASPing deeper (.3.5 cm) exposes single rock strata in-situ. Where a geologist fs hammer can only expose unweathered layers of rock, the RASP can do the same, and then has the added ability to capture and process samples into powder with particle sizes less than 150 microns, making it easier for XRD/XRF (x-ray diffraction/x-ray fluorescence). The tool uses a rotating rasp bit (or two counter-rotating bits) that resides inside or above the catch container. The container has an open slot to allow the bit to extend outside the container and to allow cuttings to enter and be caught. When the slot and rasp bit are in contact with a substrate, the bit is plunged into it in a matter of seconds to reach pristine rock. A user in the field may sample a rock multiple times at multiple depths in minutes, instead of having to cut out huge, heavy rock samples for transport back to a lab for analysis. Because of the speed and accuracy of the RASP, hundreds of samples can be taken in one day. RASP-acquired samples are small and easily carried. A user can characterize more area in less time than by using conventional methods. The field-deployable RASP used a Ni

    2010-10-01

    What processes best explain women's underrepresentation in science, math, and engineering fields in the U.S.? Do they also explain men's underrepresentation in the humanities? Two survey studies across two U.S. West Coast universities (N = 62; N = 614) addressed these questions in the context of two fields: one male-dominated (computer science) and the other female-dominated (English). Among a set of social predictors-including perceived similarity to the people in the field, social identity threats, and expectations of success-the best mediator of women's lower interest in computer science and men's lower interest in English was perceived similarity. Thus, changing students' social perceptions of how they relate to those in the field may help to diversify academic fields.

    Orloff, Teresa Lynn

    The goal of this study was to investigate the importance of five factors on the interest and persistence of females in science. The five factors were: (1) science teachers; (2) parents; (3) one-on-one mentoring; (4) summer and extracurricular science programs; and (5) the media (television, movies, radio, computers). Data was collected through 201 questionnaires distributed equally to three groups of scientists: (1) science teachers; (2) research faculty; and (3) community professionals. Data analysis consisted of nonparametric statistical tests of significance to determine which of the five factors are the most influential. The results of the data analysis revealed the relative order of importance of the five factors on the interest and persistence of females in science as: (1) Science teachers and (2) parents. (3) Summer/extracurricular science programs. (4) Mentors. (5) Media. Three conclusions were derived from this study. First, females are influenced more by people than programs. Unlike males, females define themselves in relation to other people. The people who have the most influence in young females are those people such as teachers and parents who have the most contact with young girls. Females feel safe in such relationships and with a sense of trust comes a feeling of confidence to pursue desires and interests. Second, females place importance on lasting relationships. The relationships that have the most influence on young females are those where trust and confidence have a chance to form over time. Women in the position of long term relationships with young girls such as teachers and parents, need to become active mentors in helping girls choose careers. Third, elementary teachers are not influential towards the interest and persistence of females in science. Many elementary teachers are not comfortable teaching science and therefore spend little time teaching science to their classes. Stronger emphasis in teacher education programs on science and

    Full Text Available In the conditions of globalization all the companies try to find the effective ways of maximizing their profit. One of the instruments is the system of the transfer pricing that helps to optimize the costs and allocate effective the resources of the company. Transfer pricing has detrimental effect on the economy of countries, though the governments use the regulations to minimize this effect on their economy. In this case the conflict of interests appears. Paper deals with an analysis of the functions and reasons of the economic agents which use the transfer prices to demonstrate the conflict of interests in transfer pricing. The purpose of the study is the determination of the best ways to solve the conflict situations in the process of transfer pricing according to the economic interests of the agents: company and government and within the company: headquarters and subsidiaries. The main point of resolving the conflict between company and government is to make clear regulations of transfer pricing for enterprises and productive relations between company and government. The methods to resolve the conflict within the company are: clear guidelines, decentralization and motivation for stuff members.

    Full Text Available This study’s main objective is to analyse an econometric model for forecasting purposes concerning the interest rate which is adopted as standard reference within the Brazilian economy, namely, the Actual-Selic rate, so as to verify the feasibility of performing short term predictions as to its variations. Thus the major variables that impact the Actual-Selic rate, such as price variations of agricultural and power commodities, national industrial production level, exchange rate and public sector net debt, are detailed. The modern macroeconomic approach describes the relevance of the Central Bank upon achievement of its goals so as to maintain the economic stability, amongst which lies the convergence of verified interest rates with the Selic rate target, as set forth by the Monetary Policy Committee (COPOM. Furthermore, this study poses to explain the relevance in forecasting, with a reasonable level of accuracy, the benchmark interest rate of Brazilian economy. The proposed model may be used to support decision making concerning investment strategies and as an additional tool for the monitoring of the achievement of macroeconomic policy objectives.

  5. Public healthcare interests require strict competition enforcement.

    Loozen, Edith M H

    2015-07-01

    Several countries have introduced competition in their health systems in order to maintain the supply of high quality health care in a cost-effective manner. The introduction of competition triggers competition enforcement. Since healthcare is characterized by specific market failures, many favor healthcare-specific competition enforcement in order not only to account for the competition interest, but also for the healthcare interests. The question is whether healthcare systems based on competition can succeed when competition enforcement deviates from standard practice. This paper analyzes whether healthcare-specific competition enforcement is theoretically sound and practically effective. This is exemplified by the Dutch system that is based on regulated competition and thus crucially depends on getting competition enforcement right. Governments are responsible for correcting market failures. Markets are responsible for maximizing the public healthcare interests. By securing sufficient competitive pressure, competition enforcement makes sure they do. When interpreted according to welfare-economics, competition law takes into account both costs and benefits specific market behavior may have for healthcare. Competition agencies and judiciary are not legitimized to deviate from standard evidentiary requirements. Dutch case law shows that healthcare-specific enforcement favors the healthcare undertakings concerned, but to the detriment of public health care. Healthcare-specific competition enforcement is conceptually flawed and counterproductive. In order for healthcare systems based on competition to succeed, competition enforcement should be strict.

    Mullick, Nirjhar; Buske, Stefan

    2014-05-01

    The receiver function method is a widely applied and powerful technique to obtain structural information of the crust and mantle. In its standard implementation, the depths to interfaces are interpreted from the arrival time delay of waves converted at these interfaces relative to the direct P waves. In recent times, common methods from exploration seismics (e.g. Kirchhoff prestack depth migration) have been used to image the converters instead. However, these methods are in principle not designed for receiver function imaging because of the usually non-uniform and less dense source-receiver coverage, which may lead to results dominated by significant migration noise. In this study, we present a new imaging technique that works by restricting the migration operator to the Fresnel zone in the vicinity of the conversion point at the converter. Both a synthetic test and an application to a real data set show great improvements of image quality over standard Kirchhoff migration results particularly in the case of less favorable source receiver geometry.

  13. Receiving Assistance and Local Food System Participation

    Directory of Open Access Journals (Sweden)

    Rebecca L. Som Castellano

    2017-02-01

    Full Text Available A body of literature has noted that local food systems (LFSs may not involve active participation by individuals with lower incomes. This is, in part, a function of racial and class hegemony, as well as physical and financial accessibility of LFSs. LFS institutions, such as farmers’ markets, have been working to facilitate receipt of food assistance programs, such as the Supplemental Nutrition Assistance Program (SNAP. Charitable assistance programs, such as food banks, have also been actively working to engage in LFSs, for example, by making local foods available. However, little research has explored the role that receiving public or charitable assistance can play in influencing LFS participation. In this article, I utilize quantitative and qualitative data collected from across the state of Ohio to examine the relationship between receiving assistance and LFS participation for women, who remain predominately responsible for food provisioning in the U.S., including among those who participate in LFSs. Quantitative results suggest that receiving assistance can increase participation in LFSs. Qualitative data provides more nuanced information about the importance of food assistance for women who want to participate in LFSs, and suggest that it is essential that food cooperatives and farmers’ markets are equipped to receive food assistance programs, such as SNAP, in order for women with lower incomes to participate in LFSs.

  1. What makes science interesting? Investigating middle school students' interest in school science

    Science.gov (United States)

    Swarat, Su L.

    Given the reasonable assumption that interest motivates learning, an important goal of science education ought to be to foster students' interest in science. Recent research, however, has reported a trend of low or declining interest in science among young students, which suggests that school science has not been effective in meeting this goal. A review of relevant literature reveals that current knowledge on what makes science interesting to students is very limited. This dissertation research is thus aimed at contributing to our understanding of what makes science interesting, and for whom, with a focus on school science. Using instructional episodes as the unit of analysis, this study investigated the effect of curricular elements, learning environment factors, and individual student characteristics on student interest. Using a mixed method approach involving large-scale questionnaires (quantitative) and in-depth in situ studies (qualitative), middle school students' interest both in hypothetical learning situations and as it occurs in actual science classrooms was examined. The findings indicate that when judging the interestingness of an instructional episode, students focus on the form of activity rather than content topics and learning goals. In particular, activities that allow students to be actively engaged (either physically or intellectually) elicit relatively high interest, whereas activities that are passive in nature tend to be perceived as uninteresting. From the individual perspective, students' motivation orientations seem to explain much of the between-individual differences, with students who prefer challenging learning situations and who care about scientific issues demonstrating higher interest in science.

  5. The performance analysis of linux networking - packet receiving

    Energy Technology Data Exchange (ETDEWEB)

    Wu, Wenji; Crawford, Matt; Bowden, Mark; /Fermilab

    2006-11-01

    The computing models for High-Energy Physics experiments are becoming ever more globally distributed and grid-based, both for technical reasons (e.g., to place computational and data resources near each other and the demand) and for strategic reasons (e.g., to leverage equipment investments). To support such computing models, the network and end systems, computing and storage, face unprecedented challenges. One of the biggest challenges is to transfer scientific data sets--now in the multi-petabyte (10{sup 15} bytes) range and expected to grow to exabytes within a decade--reliably and efficiently among facilities and computation centers scattered around the world. Both the network and end systems should be able to provide the capabilities to support high bandwidth, sustained, end-to-end data transmission. Recent trends in technology are showing that although the raw transmission speeds used in networks are increasing rapidly, the rate of advancement of microprocessor technology has slowed down. Therefore, network protocol-processing overheads have risen sharply in comparison with the time spent in packet transmission, resulting in degraded throughput for networked applications. More and more, it is the network end system, instead of the network, that is responsible for degraded performance of network applications. In this paper, the Linux system's packet receive process is studied from NIC to application. We develop a mathematical model to characterize the Linux packet receiving process. Key factors that affect Linux systems network performance are analyzed.

    2016-10-01

    In this dialogue with Monica Ridgeway and Randy Yerrick's Whose banner are we waving?: exploring STEM partnerships for marginalized urban youth, I engage the critical race theory (CRT) tenet of interest convergence. I first expand Derrick Bell's (1980) initial statement of interest convergence with subsequent scholarly work in this area. I then explore ways CRT in general and interest convergence specifically have been applied in the field of education. Using this framing, I examine how interest convergence may be shed new insights into Monica Ridgeway and Randy Yerrick's study. For example, the tenet of interest convergence is used to frame why it was beneficial for the White artist, Jacob, and the Achievement Scholars to collaborate in the service-learning mural. Then the idea of interest divergence is brought into explore the ways in which Jacob benefitted from his participation in the service learning project while the Achievement Scholars were left with an unfinished project which they had to problem solve. To conclude, I provide future directions for the application of interest convergence and divergence to issues facing science education.

    Full Text Available Reading is an important part of our daily life, and rapid responses to emotional words have received a great deal of research interest. Our study employed rapid serial visual presentation to detect the time course of emotional noun processing using event-related potentials. We performed a dual-task experiment, where subjects were required to judge whether a given number was odd or even, and the category into which each emotional noun fit. In terms of P1, we found that there was no negativity bias for emotional nouns. However, emotional nouns elicited larger amplitudes in the N170 component in the left hemisphere than did neutral nouns. This finding indicated that in later processing stages, emotional words can be discriminated from neutral words. Furthermore, positive, negative, and neutral words were different from each other in the late positive complex, indicating that in the third stage, even different emotions can be discerned. Thus, our results indicate that in a three-stage model the latter two stages are more stable and universal.

    Full Text Available A new consensus in the theory of monetary policy has been reached pointing to the pivotal role of interest rates that are set in accordance with central banks' reaction functions. The decisive criterion of assessing the Taylor rule, inflation and monetary targeting is not the macrotheoretic foundation of these concepts. They serve as "languages" coordinating heterogeneous beliefs among policy makers and private agents, and should also allow rule-based discretionary policies when markets are in need of leadership. Contrary to the ECB dogma, the Fed is right to have an eye on the risks of inflation and unemployment.

Qualitative descriptive design and focus groups. The Faculty of Medicine at the University of Toronto in Ontario. A total of 45 students in the undergraduate medical school program at the University of Toronto participated in this study. Approximately equal numbers of students from each year were represented in the sample. Focus groups were conducted to determine students' knowledge of, experiences with, and perspectives on the IgFM. The focus groups were audiotaped and transcribed verbatim. Transcripts were coded and analyzed for themes using qualitative content analysis. Data were collected until saturation of emerging themes was reached. The students were generally knowledgeable about the IgFM and many had attended IgFM events. The IgFM had different effects on students depending on their level of interest in family medicine (FM). For those already interested in FM, the IgFM helped to maintain and support that interest. For students still undecided about their career choices, the IgFM helped to support continued interest in FM by dispelling negative myths about the discipline, providing positive peer influences, and supplying information about careers in FM. For students not interested in FM, the IgFM provided helpful information about the discipline. Students also had many useful suggestions regarding the future direction of the IgFM. The IgFM has been successful in increasing medical student exposure to FM and in supporting students' interest in this discipline. Information from this study also provides strategies for future direction to the IgFM and other family medicine interest groups in Canada and the United States.

    2010-09-01

    The performance of a diagnostic test in the case of a binary predictor can be evaluated using the measures of sensitivity and specificity. However, in many instances, we encounter predictors that are measured on a continuous or ordinal scale. In such cases, it is desirable to assess performance of a diagnostic test over the range of possible cutpoints for the predictor variable. This is achieved by a receiver operating characteristic (ROC) curve that includes all the possible decision thresholds from a diagnostic test result. In this brief report, we discuss the salient features of the ROC curve, as well as discuss and interpret the area under the ROC curve, and its utility in comparing two different tests or predictor variables of interest.

    A comprehensive study of optical and mechanical properties of quartz glass (fused silica) with regard to application in high temperature solar receivers is presented. The dependence of rupture strength on different surface conditions as well as high temperature is analyzed, focussing particularly on damage by devitrification and sandblasting. The influence of typical types of contamination in combination with thermal cycling on the optical properties of fused silica is determined. Cleaning methods are compared regarding effectiveness on contamination-induced degradation for samples with and without antireflective coating. The FEM-aided design of different types of receiver windows and their support structure is presented. A large-scale production process has been developed for producing fused silica dome shaped windows (pressurized window) up to a diameter of 816 mm. Prototypes were successfully pressure-tested in a test bench and certified according to the European Pressure Vessel Directive.

  19. Physicians, social media, and conflict of interest.

    Decamp, Matthew

    2013-02-01

    Physicians and patients increasingly use social media technologies, such as Facebook, Twitter, and weblogs (blogs), both professionally and personally. Amidst recent reports of physician misbehavior online, as well as concerns about social media's potential negative effect on trust in the medical profession, several national-level physician organizations have created professional guidelines on social media use by physicians. Missing from these guidelines is adequate attention to conflict of interest. Some guidelines do not explicitly mention conflict of interest; others recommend only disclosure. Recommending disclosure fails to appreciate the unique features of social media that make adequate disclosure difficult to accomplish. Moreover, in emphasizing disclosure alone, current guidelines are inconsistent with medicine's general trend toward management or elimination, not just disclosure, of potential conflicts. Because social media sites typically rely on physicians' voluntary compliance with professional norms, physicians necessarily play a major role in shaping these norms' content and scope. To achieve the benefits of social media and ensure the veracity of social media content while preserving trust in the profession, physicians must reaffirm their commitment to disclose potential conflicts; advocate for better electronic disclosure mechanisms; and develop concrete management strategies-including, where necessary, the elimination of conflicts altogether.

  20. Social Inclusion Facilitates Interest in Mating

    Directory of Open Access Journals (Sweden)

    Christina M. Brown

    2009-01-01

    Full Text Available According to a life history framework, variability across an organism's lifespan necessitates trade-offs between behaviors that promote survival and those that promote reproduction. Adopting this perspective, the current work investigates how social acceptance or rejection can influence the differential priority placed on mating and survival motivations. Because social acceptance is an important survival-related cue (i.e., group living provides protection from predators and sharing of resources, we predicted that recent experiences of social acceptance should increase people's motivation to mate. In support of this prediction, Study 1 found that participants who were included in an electronic ball-toss game showed more interest in mating (regardless of the potential mate's attractiveness than excluded and control participants. In Study 2, participants who recalled an experience of social acceptance viewed sexual affiliation as more important than did participants in rejection and control conditions. Collectively, these results suggest an adaptive trade-off such that interest in mating increases upon satiation of affiliative needs. Furthermore, these findings demonstrate that the experience of social acceptance can have unique effects and should not be treated as the sole comparison condition when studying social rejection.

    Full Text Available Virtual reality and images conquer them permanently and irrevocably even children from the earliest age. For instance, I can say that as they grow departs books. So many young people arrive at teens refuse to read a book, even electronically. Children considered mandatory reading something imposed by adults and tries to escape, finding other concerns. They also have no motivation, the universe discovered through books hardly seems interesting, which is, in their opinion, obsolete. The environment in which I work led me to satisfy my curiosity namely that of finding out to what extent reading is among the priorities of young people today. This research considers the study of attitudes, behaviors, opinions and intentions of young people their interest in reading, be it physical or books in electronic format.

  2. Searching Trajectories by Regions of Interest

    KAUST Repository

    Shang, Shuo

    2017-03-22

    With the increasing availability of moving-object tracking data, trajectory search is increasingly important. We propose and investigate a novel query type named trajectory search by regions of interest (TSR query). Given an argument set of trajectories, a TSR query takes a set of regions of interest as a parameter and returns the trajectory in the argument set with the highest spatial-density correlation to the query regions. This type of query is useful in many popular applications such as trip planning and recommendation, and location based services in general. TSR query processing faces three challenges: how to model the spatial-density correlation between query regions and data trajectories, how to effectively prune the search space, and how to effectively schedule multiple so-called query sources. To tackle these challenges, a series of new metrics are defined to model spatial-density correlations. An efficient trajectory search algorithm is developed that exploits upper and lower bounds to prune the search space and that adopts a query-source selection strategy, as well as integrates a heuristic search strategy based on priority ranking to schedule multiple query sources. The performance of TSR query processing is studied in extensive experiments based on real and synthetic spatial data.

  3. A review of rapid solidification studies of intermetallic compounds

    Koch, C. C.

    1985-01-01

    A review of rapid solidification studies of high-temperature ordered intermetallic compounds is presented. Emphasis is on the nickel - and iron- aluminides which are of potential interest as structural materials. The nickel-base aluminides which have been rapidly solidified exhibit changes in grain size, compositional segregation, and degree of long range order (as reflected in APB size and distribution) which markedly affect mechanical properties. Some experiments indicate the formation of a metastable L1(2) phase in rapidly solidified Fe-(Ni,Mn)-Al-C alloys, while other work observes only a metastable fcc phase in the same composition range. The metastable phases and/or microstructures in both nickel and iron aluminides are destroyed by annealing at temperatures above 750 K, with subsequent degradation of mechanical properties. Rapid solidification studies of several other intermetallic compounds are briefly noted.

    2017-06-01

    To describe hypersensitivity reactions in patients receiving maintenance hemodialysis. PubMed search of articles published during the past 30 years with an emphasis on publications in the past decade. Case reports and review articles describing hypersensitivity reactions in the context of hemodialysis. Pharmacologic agents are the most common identifiable cause of hypersensitivity reactions in patients receiving hemodialysis. These include iron, erythropoietin, and heparin, which can cause anaphylactic or pseudoallergic reactions, and topical antibiotics and anesthetics, which lead to delayed-type hypersensitivity reactions. Many hypersensitivity reactions are triggered by complement activation and increased bradykinin resulting from contact system activation, especially in the context of angiotensin-converting enzyme inhibitor use. Several alternative pharmacologic preparations and dialyzer membranes are available, such that once an etiology for the reaction is established, recurrences can be prevented without affecting the quality of care provided to patients. Although hypersensitivity reactions are uncommon in patients receiving hemodialysis, they can be life-threatening. Moreover, considering the large prevalence of the end-stage renal disease population, the implications of such reactions are enormous. Most reactions are pseudoallergic and not mediated by immunoglobulin E. The multiplicity of potential exposures and the complexity of the environment to which patients on dialysis are exposed make it challenging to identify the precise cause of these reactions. Great diligence is needed to investigate hypersensitivity reactions to avoid recurrence in this high-risk population. Copyright © 2017 American College of Allergy, Asthma & Immunology.

    2016-05-01

    Alstom is developing concentrated solar power (CSP) utilizing 60/40wt% NaNO3-KNO3 molten salt as the working fluid in a tower receiver for the global renewable energy market. In the CSP power generation cycle, receivers undergo a daily cyclic operation due to the transient nature of solar energy. Development of robust and efficient start-up and shut-down procedures is critical to avoiding component failures due to mechanical fatigue resulting from thermal transients, thus maintaining the performance and availability of the CSP plant. The Molten Salt Central Receiver (MSCR) is subject to thermal transients during normal daily operation, a cycle that includes warmup, filling, operation, draining, and shutdown. This paper describes a study to leverage dynamic simulation and finite element analysis (FEA) in development of start-up, shutdown, and transient operation concepts for the MSCR. The results of the FEA also verify the robustness of the MSCR design to the thermal transients anticipated during the operation of the plant.

    Amiodarone is a commonly used antiarrhythmic drug. Hepatotoxicity following chronic oral administration occurs in 1% to 3% of patients. Hepatotoxicity following intravenous (IV) administration is infrequent but may be associated with dramatic increases in serum transaminases. We describe the incidence of liver toxicity among patients receiving IV amiodarone during a 5-year period. This was a single-center retrospective review of patients receiving IV amiodarone for any cause. The outcome measures were development of elevated serum transaminases and the relation of transaminitis to all-cause 30-day mortality. A total of 1510 patients received amiodarone intravenously between 2005 and 2011; 77 (5%) developed elevated liver enzymes. Enzyme elevation was divided into mild (100-300 IU/L), moderate (300-1000 IU/L), and severe (>1000 IU/L). The median alanine aminotransferase was 189 (37-10,006) IU/L and aspartate aminotransferase was 253 (84-12,005) IU/L. The 30-day mortality among those with transaminitis was 22%; however, no patient died of amiodarone-related liver disease. Amiodarone can cause severe elevation in liver enzymes. The incidence of severe transaminitis is low; deaths following IV amiodarone are rarely caused by drug-induced liver failure.

    Full Text Available New methodologies, engineering processes, and support environments are beginning to emerge for embedded signal processing systems. The main objectives are to enable defence industry to field state-of-the-art products in less time and with lower costs, including retrofits and upgrades, based predominately on commercial off the shelf (COTS components and the model-year concept. One of the cornerstones of the new methodologies is the concept of rapid prototyping. This is the ability to rapidly and seamlessly move from functional design to the architectural design to the implementation, through automatic code generation tools, onto real-time COTS test beds. In this paper, we try to quantify the term “rapid” and provide results, the metrics, from two independent benchmarks, a radar and sonar beamforming application subset. The metrics show that the rapid prototyping process may be sixteen times faster than a conventional process.

    2017-06-01

    Due to the improvement of the picture quality of closed-circuit television (CCTV), the demand for CCTV has increased rapidly and its market size has also increased. The current system structure of CCTV transfers compressed images without analysis received from CCTV to a control center. The compressed images are suitable for the evidence required for a criminal arrest, but they cannot prevent crime in real time, which has been considered a limitation. Thus, the present paper proposes a system implementation that can prevent crimes by applying a situation awareness system at the back end of the CCTV cameras for image acquisition to prevent crimes efficiently. In the system implemented in the present paper, the region of interest (ROI) is set virtually within the image data when a barrier, such as fence, cannot be installed in actual sites and unauthorized intruders are tracked constantly through data analysis and recognized in the ROI via the developed algorithm. Additionally, a searchlight or alarm sound is activated to prevent crime in real time and the urgent information is transferred to the control center. The system was implemented in the Raspberry Pi 2 board to be run in real time. The experiment results showed that the recognition success rate was 85% or higher and the track accuracy was 90% or higher. By utilizing the system, crime prevention can be achieved by implementing a social safety network.

    2007-05-01

    The biopsychosocial paradigm is now the main model when dealing with most human health disorders. One of the strengths of this model is that it encourages broader thinking when assessing and managing patients. It also encourages broader reading into areas not traditionally associated with manual therapy. Immunology and neuroscience are amongst the fastest growing medical sciences. These fields come together in the relatively new area of psychoneuroimmunolgy. This article examines some findings from these fields that are not widely discussed in the physical therapy professions. These findings are of relevance to many of the disciplines within the physical therapies. It is the authors aim to stimulate further interest in the relevant, yet often under explored areas of immunology and psychoneuroimmunology.

  18. Evolutionary medicine: its scope, interest and potential.

    Science.gov (United States)

    Stearns, Stephen C

    2012-11-07

    This review is aimed at readers seeking an introductory overview, teaching courses and interested in visionary ideas. It first describes the range of topics covered by evolutionary medicine, which include human genetic variation, mismatches to modernity, reproductive medicine, degenerative disease, host-pathogen interactions and insights from comparisons with other species. It then discusses priorities for translational research, basic research and health management. Its conclusions are that evolutionary thinking should not displace other approaches to medical science, such as molecular medicine and cell and developmental biology, but that evolutionary insights can combine with and complement established approaches to reduce suffering and save lives. Because we are on the cusp of so much new research and innovative insights, it is hard to estimate how much impact evolutionary thinking will have on medicine, but it is already clear that its potential is enormous.

    2013-01-01

    Three studies were designed to extend a combination of vested interest theory (VI) and the extended parallel process model of fear appeals (EPPM) to provide formative research for creating more effective disaster preparedness social action campaigns. The aim was to develop an effective VI scale for assessing individual awareness and 'vestedness' relevant to disaster preparedness. Typical preparedness behaviours are discussed with emphasis on earthquakes and tornados in particular. Brief overviews of VI and the EPPM are offered, and findings are presented from three studies (one dealing with earthquakes, and two with tornados) conducted to determine the factor structure of the key VI components involved, and to develop and test subscales derived from the two theories. The paper finishes with a discussion of future research needs and suggestions on how the new subscales may be applied in the design and execution of more effective disaster preparedness campaigns. © 2013 The Author(s).

    Dickinson State University organizes four Family Science Day events each fall during the months of September, October, November, and December. Activities are geared toward elementary-aged children to increase student engagement in the sciences. Offered on Saturday afternoons, each event focuses on a different science-related theme. Families can attend these events free of charge, and the kids participate in a large variety of hands-on activities that center around the event's theme. An important part of generating enthusiasm for a subject is making it interesting, and with young children art projects provide a great avenue to generate interest and enthusiasm. Such projects are fun and involve creativity, allowing the children a chance to express themselves. To this end, each of the Family Science Days includes one or more arts and crafts projects that result in a fun learning experience the children can take home. In November 2015 the art project involved creating a soil profile. The children were given a paper handout showing a soil profile sketch lined up beside a color photograph of a soil profile. They were also supplied with glue and several containers of different colored soils from surface and subsurface horizons. To create their art project, the children glued samples of soil onto their profile sketch, attempting to create a profile that looked similar to the color photograph. The handout also included fundamental information about each of the horizons shown. The children received this project with great enthusiasm. There were nine other science-based activities available at the Family Science Day when the soil art project was offered, and the art project was one of the most popular stops in the room. The children typically spent a good deal of time working on their art project, including asking questions about the various colored soils available to them and the basic properties of soil. Whether the popularity of the project came from the chance to be

    Making a conflict of interest declaration is now mandatory at continuing medical education CME accredited events. However, these declarations tend to be largely perfunctory. This study sought to better understand physician perceptions surrounding conflict of interest. The same PowerPoint (Microsoft, Canada) presentation (http://www.youtube.com/watch?v=mQSOvch7Yg0&feature=g-upl) was delivered at multiple University of Alberta and Royal College CME-accredited events to surgeons, internists, and learners. After each talk, the audience was invited to complete an anonymous, pretested, and standardized 5-point Likert scale (strongly disagree to strongly agree) questionnaire. A total of 136 surveys were analyzed from 31 surgeons, 49 internists, and 56 learners. In response to the question regarding whether by simply making a declaration, the speaker had provided adequate proof of any conflicts of interest, 71% of surgeons thought so, whereas only 35% of internists and 39% of learners agreed or strongly agreed (P = .004). Further probing this theme, the audience was asked whether a speaker must declare fees or monies received from industry for consulting, speaking, and research support. Once again there was a variance of opinion, with only 43% of surgeons agreeing or strongly agreeing with this statement; yet, 80% of internists and 71% of learners felt that such a declaration was necessary (P = .013). On the topic of believability (a speaker declaration makes him or her and the presentation more credible), the 3 groups were less polarized: 50% of surgeons, 41% of internists, and 52% of learners (P = .2) felt that this was the case. Although two thirds of surgeons (68%) and learners (66%) and nearly all internists (84%) felt that industry-sponsored research was biased, these differences were not significant (P = .2). Even when they are completely open and honest, conflict of interest declarations do not negate the biases inherent in a speaker's talk or research when it is

  2. STIMULATING STUDENT INTEREST IN DESIGN HISTORY CLASSES

    Full Text Available With history being an established course in design education and sparking creativity being one of design education’s primary objectives, questions arise as to: What forms of history teaching capture student interest? How can the lessons of history resonate with youth in ways that tie the past to the present? How can assignments spark excitement in students and engender a passion for the subject? And, where can faculty draw inspiration from in re-envisioning the role that history can play in their program and profession? Two interior design educators from the University of Minnesota share techniques, assignments, and pedagogies that respond to the above questions and help set a trajectory for both creatively teaching design history and sparking students’ interest and creative potential. Going beyond traditional methodologies and discourses around the teaching of history, these educators take a unique perspective and strive for a diverse set of objectives. Employing techniques such as digital games and free-hand sketching, they challenge students to engage with the material first hand. By tying a design project into a history course, they present students with the opportunity to conceive of ways to bridge the past, present, and future. Infusing history classes with creative and critical thinking that encompasses and responds to pressing social concerns reinforces the meaning of history classes and makes history relevant to students’ lives. Through this sharing, the authors aim to spark a dialogue across the disciplines around the teaching of history and makes history relevant to students’ lives. Through this sharing, the authors aim to spark a dialogue across the disciplines around the teaching of history and the renewed role it can play in design education.

    Tampere is third largest city in Finland and a regional centre. During 70's there occurred several communal mergers. Nowadays this local area has both strong and diversed identity - from wilderness and agricultural fields to high density city living. Outside the city center there are interesting geological points unknown for modern city settlers. There is even a local proverb, "Go abroad to Teisko!". That is the area the Hidden Treasures -student project is focused on. Our school Tammerkoski Upper Secondary School (or Gymnasium) has emphasis on visual arts. We are going to offer our art students scientific and artistic experiences and knowledge about the hidden treasures of Teisko area and involve the Teisko inhabitants into this project. Hidden treasures - Precambrian subduction zone and a volcanism belt with dense bed of gold (Au) and arsenic (As), operating goldmines and quarries of minerals and metamorphic slates. - North of subduction zone a homogenic precambrian magmastone area with quarries, products known as Kuru Grey. - Former ashores of post-glasial Lake Näsijärvi and it's sediments enabled the developing agriculture and sustained settlement. Nowadays these ashores have both scenery and biodiversity values. - Old cattle sheds and dairy buildings made of local granite stones related to cultural stonebuilding inheritance. - Local active community of Kapee, about 100 inhabitants. Students will discover information of these "hidden" phenomena, and rendering this information trough Enviromental Art Method. Final form of this project will be published in several artistic and informative geocaches. These caches are achieved by a GPS-based special Hidden Treasures Cycling Route and by a website guiding people to find these hidden points of interests.

    2017-10-01

    RapidIO (http://rapidio.org/) technology is a packet-switched high-performance fabric, which has been under active development since 1997. Originally meant to be a front side bus, it developed into a system level interconnect which is today used in all 4G/LTE base stations world wide. RapidIO is often used in embedded systems that require high reliability, low latency and scalability in a heterogeneous environment - features that are highly interesting for several use cases, such as data analytics and data acquisition (DAQ) networks. We will present the results of evaluating RapidIO in a data analytics environment, from setup to benchmark. Specifically, we will share the experience of running ROOT and Hadoop on top of RapidIO. To demonstrate the multi-purpose characteristics of RapidIO, we will also present the results of investigating RapidIO as a technology for high-speed DAQ networks using a generic multi-protocol event-building emulation tool. In addition we will present lessons learned from implementing native ports of CERN applications to RapidIO.

    Full Text Available Writing-to-learn assignments typically foster deep comprehension of learning contents. Journal writing, in particular, promotes the application of learning strategies, which promote learners’ comprehension, interest in a topic and ability to critically reflect on learning contents. Against this background, we conducted two longitudinal field studies. In Study 1, twenty-one students wrote learning journal entries after their biology lessons. After the intervention period, they showed better scores in comprehension, interest and critical reflection than the control class, in which students (n=25 completed other homework assignments. Mediation analyses revealed a domino effect: Journal writing improved comprehension, which led to raised interest, which resulted in superior critical reflection. Study 2 further investigated the role of learners’ interest in improving critical reflection. Students in the experimental condition (n=13 received a personal-utility prompt in addition to cognitive and metacognitive prompts to support journal writing. In the control group (n=11, students only received cognitive and metacognitive prompts. The experimental group showed higher interest scores after the intervention period and a better quality of critical reflections on a bio-ethical issue than the control group. Together, these studies illustrate the potentials of journal writing for improving learners’ comprehension, their interest and ability to critically reflect on complex scientific issues.

  6. Performance Driven Six-Port Receiver and Its Advantages over Low-IF Receiver Architecture

    2014-01-01

    Full Text Available This paper provides an extensive analysis of the performance of a six-port based direct conversion receiver (SPR in terms of signal quality, dynamic range, noise figure, ports matching, isolation, bandwidth, and cost. Calibration technique using multimemory polynomials has been adopted in order to improve the signal quality of the six-port receiver. The performances of the calibrated receiver are then compared with the performances of a commercially available I-Q demodulator used as a low-IF receiver. The main advantages and disadvantages of the SPR compared to the low-IF receiver are highlighted. The major advantages of the SPR come in terms of its available input frequency bandwidth and the low power requirement. The SPR system requires no external bias supply but suffers in terms of the available conversion gain. A better port matching of the SPR can be guaranteed over a wide frequency bandwidth, which mixer based receiver systems lack. The main component limiting the performance of a SPR is the diode detector. A faster and a better diode detector will alleviate some of the problems highlighted in this paper. The SPR system is calibratable and its error-vector-magnitude performance can be made better than the I-Q demodulator used as a low-IF receiver.

    The comet assay is a rapid, sensitive and relatively simple method for measuring DNA damage. A bibliometric study was performed to evaluate temporal and geographical trends, research quality and main areas of interest in scientific production in this field. A PubMed search strategy was developed and 7674 citations were retrieved in the period 1990-2013. Notably, the MeSH (Medical Subject Headings) term 'comet assay', officially introduced in 2000, is used by indexers only in two thirds of papers retrieved. Articles on the comet assay were published in 78 countries, spread over the 5 continents. The EU contributed the greatest output, producing >2900 articles with IF (42.0%) and totalling almost 10000 IF points, and was followed by USA. In the new millennium, research with this assay reached a plateau or slow decline in the most industrialised areas (USA, Germany, UK, Italy), while its use has boomed in emerging countries, with increases of 5- to 7-fold in the last 10 years in China, India and Brazil, for instance. This transition resulted in a slow decrease of scientific production quality, as the countries that increased their relative weight typically had lower mIFs. The most common MeSH terms used in papers using the comet assay referred to wide areas of interest, such as DNA damage and repair, cell survival and apoptosis, cancer and oxidative stress, occupational and environmental health. Keywords related to humans, rodents and cell culture were also frequently used. The top journal for the comet assay articles was found to be Mutation Research, followed by Mutagenesis. Most papers using the comet assay as a biomarker were published in genetic and toxicology journals, with a stress on environmental and occupational disciplines. © The Author 2014.

    We suggest a market design for rapid demand response in electricity markets. The solution consists of remotely controlled switches, meters, forecasting models as well as a flexible auction market to set prices and select endusers job by job. The auction market motivates truth-telling and makes...... it simple to involve the endusers in advance and to activate demand response immediately. The collective solution is analyzed and economic simulations are conducted for the case of Kenya. Kenya has been su ering from unreliable electricity supply for many years and companies and households have learned...... as the Transmission System Operator (TSO) requests demand response and the winning endusers are disconnected immediately if the TSO accepts the result of the auction. The endusers are compensated with a uniform auction price job by job and the Aggregator receives part of the surplus. The simulation captures...

  13. Receivers Gather Data for Climate, Weather Prediction

    Science.gov (United States)

    2012-01-01

    Signals from global positioning system (GPS) satellites are now being used for more than just location and navigation information. By looking at the radio waves from GPS satellites, a technology developed at NASA s Jet Propulsion Laboratory (JPL) not only precisely calculates its position, but can also use a technique known as radio occultation to help scientists study the Earth s atmosphere and gravity field to improve weather forecasts, monitor climate change, and enhance space weather research. The University Corporation for Atmospheric Research (UCAR), a nonprofit group of universities in Boulder, Colorado, compares radio occultation to the appearance of a pencil when viewed though a glass of water. The water molecules change the path of visible light waves so that the pencil appears bent, just like molecules in the air bend GPS radio signals as they pass through (or are occulted by) the atmosphere. Through measurements of the amount of bending in the signals, scientists can construct detailed images of the ionosphere (the energetic upper part of the atmosphere) and also gather information about atmospheric density, pressure, temperature, and moisture. Once collected, this data can be input into weather forecasting and climate models for weather prediction and climate studies. Traditionally, such information is obtained through the use of weather balloons. In 1998, JPL started developing a new class of GPS space science receivers, called Black Jack, that could take precise measurements of how GPS signals are distorted or delayed along their way to the receiver. By 2006, the first demonstration of a GPS radio occultation constellation was launched through a collaboration among Taiwan s National Science Council and National Space Organization, the U.S. National Science Foundation, NASA, the National Oceanic and Atmospheric Administration (NOAA), and other Federal entities. Called the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC

    In this letter, we develop optimal parameters for a structure which is suitable for the realization of a coherent quantum receiver. Conditions including predefined photon wavelength, strain, small Zeeman splitting of the electron levels, and large Zeeman effect for quantum-confined light holes are satisfied simultaneously for the structure based on the InGaAsP solid solutions. We are able to achieve designs with wavelengths of 1.3 and 1.55 μm that are desirable for optoelectronic applications.

    2014-01-01

    Purpose We surveyed parents to ascertain interest in newborn genomic testing and determine whether these queries would provoke refusal of conventional newborn screening (NBS). Methods After brief genetics orientation, parents rated their interest in receiving genomic testing for their healthy newborn on a 5-point Likert scale and answered questions about demographics and health history. We used logistic regression to explore factors associated with interest in genomic testing and tracked any subsequent rejection of NBS. Results We queried 514 parents within 48 hours after birth while still in the hospital (mean age (sd) 32.7 (6.4) years, 65.2% female, 61.2% white, 79.3% married). Parents reported being not at all (6.4%), a little (10.9%), somewhat (36.6%), very (28.0%) or extremely (18.1%) interested in genomic testing for their newborns. None refused conventional NBS. Married participants and those with health concerns about their infant were less interested in newborn genomic testing (p=0.012 and p=0.030, respectively). Mothers’ and fathers’ degree of interest was discordant (≥ 2 categories different) in 24.4% of couples. Conclusions Interest in newborn genomic testing was high among parents of healthy newborns and the majority of couples had similar levels of interest. Surveying parents about genomic sequencing did not prompt rejection of NBS. PMID:25474344

  19. Making space more interesting to elementary students

    Edlund, J.

    When in life do we take the big decision of deciding which path in our career we are going to take? Is this decision made from our experiences in school or is it taken before? Do our family or our friends hopes and dreams for us have any impact on our decision? These are questions that are useful for understanding why some people choose to work with science and why other has chosen another career. In my work to help the university to recruit new student to their master of science in space engineering programme, I have been visiting an elementary school and talked about different topics in space science. The pupils were very interested but when I did a survey of their dream jobs and future career I saw that most of them have hopes of a career that are based on their present talent and not on what education they are going to have. 11 out of 17 students that did this survey wanted to be some kind of artist or soccer professional. Only 4 of them had chosen a career that there are educations for. I do not think this is the situation only for this school, I think this situation is common for children I this age. Since the chance of being a pro in any sport is a really hard thing, probably the most of them have to give up their dream and chose a more realistic approach to their future career. This leaves us with a majority of the students that have not yet had their path chosen and hopefully with help of teachers and special lectures we can make science more attractive to them. This sound like an easy problem, since most of the students finds space really interesting. But there are some problems. The teachers do not have the kind of education, especially in elementary school that is needed for the kids to get proper answer to their questions. The solution is not easy. Should the teachers take more courses in physics and chemistry or should it be their responsibility to search for facts when these kinds of questions appear? I found that in some cases the student have

  20. Efficiency of the Receivable Rotation Ratio as a Measure of the Accounts Receivable Settlement Period

    2010-01-01

    Full Text Available Accounts receivable forecasting, due to a wide range of applications in a number of financial decisions, is an important area of a company’s financial forecasts. Estimation of accounts receivable involves finding solutions for two fundamental problems: forecasting the level of daily sales revenues and estimating the accounts receivable settlement period. This paper addresses the issue of constructing reliable models to be used in forecasting accounts receivable due on deliveries and services – the trend model and the simple regression model. The postulated models, together with a range of alternative methods suggested in the literature on the field, are tested to examine the quality of the resulting estimates of the A/R settlement period. The methods postulated in the paper prove to be functional – on the one hand, the results are reliable, on the other hand, the postulated models can be constructed using readily available data.

    To compare outcomes of pediatric patients treated with azithromycin compared with penicillin or cephalosporin. We hypothesized that azithromycin use would not be associated with increased cardiac mortality in the pediatric population. Retrospective cohort study from the Pediatric Health Information System database between 2008 and 2012. Patients Azithromycin was used in 5039 (6.1%); penicillin or cephalosporin was used in 77 943 (93.9%). Overall prevalence of antibiotic-associated CPR was 0.14%. Patients receiving a macrolide antibiotic had a lower prevalence of CPR compared with patients receiving a penicillin or cephalosporin (0.04% vs 0.14%, P = .04), and there was no difference in mortality. Multivariable analysis did not find an association between macrolide use and CPR. In contrast to recent adult studies, among children hospitalized for community-acquired pneumonia, azithromycin use was not associated with a greater prevalence of cardiac arrest compared with penicillin or cephalosporin use.

  2. Parabolic Trough Receiver Heat Loss Testing (Poster)

    Energy Technology Data Exchange (ETDEWEB)

    2007-03-01

    Parabolic trough receivers, or heat collection elements (HCEs), absorb sunlight focused by the mirrors and transfer that thermal energy to a fluid flowing within them. Thje absorbing tube of these receivers typically operates around 400 C (752 F). HCE manufacturers prevent thermal loss from the absorbing tube to the environment by using sputtered selective Cermet coatings on the absorber and by surrounding the absorber with a glass-enclosed evacuated annulus. This work quantifies the heat loss of the Solel UVAC2 and Schott PTR70 HCEs. At 400 C, the HCEs perform similarly, losing about 400 W/m of HCE length. To put this in perspective, the incident beam radiation on a 5 m mirror aperture is about 4500 W/m, with about 75% of that energy ({approx} 3400 W/m) reaching the absorber surface. Of the 3400 W/m on the absorber, about 3000 W/m is absorbed into the working fluid while 400 W/m is lost to the environment.

    Full Text Available The sudden growth of additive manufacturing is generating a renovated interest towards the field of rapid tooling. We propose a geometrical compensation method for rapid tools made by thermoset polyurethane. The method is based on the explicit FEM simulation coupled to a geometrical optimization algorithm for designing the stamping tools. The compensation algorithm is enhanced by considering the deviations between the stamped and designed components. The FEM model validation has been performed by comparing the results of a DOE done at different values of press force.

  18. Are dermatologists in private practice interested in teledermatological services?

    Diagnosing dermatologic skin conditions can be difficult, especially in pigmented skin lesions. Therefore, the consultation of an expert via teledermatology could prove vital. For this purpose, a rapid transfer of medical data including high resolution images is essential. This transfer can be performed with a variety of modern telecommunication technologies, including ISDN, highspeed-ISDN, Internet, and Intranet. As the levels of both communication software and camera-systems can be quite different, our survey investigated the equipment of 84 dermatologists in private practice. A questionnaire was distributed on computer equipment, operating system software, and any image documentation systems used, as well as required telecommunications equipment and possible applications of tele-dermatology. This survey showed a response rate of 54% and proves that dermatologists in private practice are interested in telemedicine services. Most dermatologists surveyed use Windows 95 operating software and 74% have access to modern ISDN modems or PC-cards. Dermatologists currently prefer applications with low-tech communication hardware and software requirements. Consultation of dermatological centers was the favored application with 59%. Our survey clearly demonstrates that a high percentage of dermatologists in private practice would use tele-dermatology. In our experience, for the excellence of this service an image documentation system is essential to provide the tele-dermatological expert with standardized images with constant illumination.

  19. Investigation for young adults’ interest in health

    Full Text Available Young adulthood is a critical period because it is the time when young people begin to live on their own, and adopt health behaviours which can influence their lifestyle and health status. In social practice there are many community belongings and community-based support systems and programs in health, which aim to increase young adults’ health literacy and offer learning possibilities and support services.The study focuses on the education and the literacy as determinants of health, several fields of health education and health promotion related to young adults, elements and determinants of health culture, the links between health and learning, adults’ interest and claims related to learning process, methods, topics. In my research I made a survey of learning methods and contents with the help of the analysis of the scientific literature and by questionnaires. I examined young adults’ (18 to 30 concepts of health and healthy lifestyle, motivations, forms of communication, learning methods and participation in community platforms of health. We use the results of this research to improve programs that support young people’s learning activities for health.

  20. Empirical evaluation of interest-level criteria

    Efficient association rule mining algorithms already exist, however, as the size of databases increases, the number of patterns mined by the algorithms increases to such an extent that their manual evaluation becomes impractical. Automatic evaluation methods are, therefore, required in order to sift through the initial list of rules, which the datamining algorithm outputs. These evaluation methods, or criteria, rank the association rules mined from the dataset. We empirically examined several such statistical criteria: new criteria, as well as previously known ones. The empirical evaluation was conducted using several databases, including a large real-life dataset, acquired from an order-by-phone grocery store, a dataset composed from www proxy logs, and several datasets from the UCI repository. We were interested in discovering whether the ranking performed by the various criteria is similar or easily distinguishable. Our evaluation detected, when significant differences exist, three patterns of behavior in the eight criteria we examined. There is an obvious dilemma in determining how many association rules to choose (in accordance with support and confidence parameters). The tradeoff is between having stringent parameters and, therefore, few rules, or lenient parameters and, thus, a multitude of rules. In many cases, our empirical evaluation revealed that most of the rules found by the comparably strict parameters ranked highly according to the interestingness criteria, when using lax parameters (producing significantly more association rules). Finally, we discuss the association rules that ranked highest, explain why these results are sound, and how they direct future research.
