    To describe methods to determine sample sizes in surveys using open-ended questions and to assess how resampling methods can be used to determine data saturation in these surveys. We searched the literature for surveys with open-ended questions and assessed the methods used to determine sample size in 100 studies selected at random. Then, we used Monte Carlo simulations on data from a previous study on the burden of treatment to assess the probability of identifying new themes as a function of the number of patients recruited. In the literature, 85% of researchers used a convenience sample, with a median size of 167 participants (interquartile range [IQR] = 69-406). In our simulation study, the probability of identifying at least one new theme for the next included subject was 32%, 24%, and 12% after the inclusion of 30, 50, and 100 subjects, respectively. The inclusion of 150 participants at random resulted in the identification of 92% themes (IQR = 91-93%) identified in the original study. In our study, data saturation was most certainly reached for samples >150 participants. Our method may be used to determine when to continue the study to find new themes or stop because of futility.

    2015-08-01

    Citizens’ opinions are crucial for action on climate change, but are, owing to the complexity of the issue, diverse and potentially unformed. We contribute to the understanding of public views on climate change and to knowledge needed by decision-makers by using a new approach to analyse answers to the open survey question `what comes to mind when you hear the words `climate change’?’. We apply automated text analysis, specifically structural topic modelling, which induces distinct topics based on the relative frequencies of the words used in 2,115 responses. From these data, originating from the new, nationally representative Norwegian Citizen Panel, four distinct topics emerge: Weather/Ice, Future/Impact, Money/Consumption and Attribution. We find that Norwegians emphasize societal aspects of climate change more than do respondents in previous US and UK studies. Furthermore, variables that explain variation in closed questions, such as gender and education, yield different and surprising results when employed to explain variation in what respondents emphasize. Finally, the sharp distinction between scepticism and acceptance of conventional climate science, often seen in previous studies, blurs in many textual responses as scepticism frequently turns into ambivalence.

    2012-10-01

    To analyse the patients' inclination to comment in generic patient surveys, and to evaluate how these comments were received and used for quality improvement by the hospitals. The study is based on quantitative and qualitative data from four rounds of patient satisfaction surveys from 1999 to 2006. The open-ended questions and their applicability were evaluated by hospital and department management teams in a survey and by hospital employees and leaders, in semi-structured interviews. Eight public hospitals in a Danish county (amt). In this study, the participants were 75 769 patients, 173 department/hospital management teams, and 24 hospital employees and leaders. Questionnaires with open-ended questions to patients and hospital/department management teams. Semi-structured interviews with hospital employees and leaders. Main outcome measure The number of comments from patients and the usefulness of the comments as perceived by employees and leaders. A total of 76% of the patients chose to add one or more comments to their questionnaires. The patients' inclination to comment increased over time. The patient's inclination to comment was highest for the most and the least satisfied patients. The comment-gathering was viewed as 'Very useful' or 'Useful' by 80.7% of the department management teams (31 responses). To gather comments and to forward these to small organizational entities seems to make patient satisfaction measurements more informative and patient-centred. The wording of the open-ended questions, the number of questions and an appeal in the cover letter appear to be important in relation to the patient's inclination to comment.

  9. Study of the polysemic term of minerality in wine: Segmentation of consumers based on their textual responses to an open-ended survey.

    2016-12-01

    Over the past 20years, the word "minerality" has been increasingly used in the description of wines. However, a precise definition of the concept of minerality appears to be inexistent, and no consensual meaning, even among wine professionals, can be identified. Although this word usage seems to spread out from wine professionals to consumers, research on what consumers assume about minerality is scarce. This paper aims to study the various concepts about minerality held by consumers by using an open-ended questionnaire. A total of 1697 French-speaking consumers responded to an online survey and their free answers were analysed using statistical textual methods. The clustering around latent variables (CLV) method was used, taking into account both the lexicon used and the personal characteristics of consumers to classify them. Word associativities were then computed by means of renormalized Markov associativities, generating textual networks associated to each group, as well as to personal characteristics of the consumers. Typically, the most inexperienced consumers confess to have never heard about minerality in wine. Then, young women, also endowed with little wine competences, mainly associate minerality to mineral ions as those found in bottled water. Slightly older consumers embed the concept of minerality into the idea of terroir. Finally, the most experienced consumers refer to sensory perceptions such as gunflint or acidity. Those findings are consistent with a lexical innovation process, diffusing from wine professionals to consumers, referring to the mineral kingdom (as opposed to animal or vegetal), and aiming to stress that the style of their wines has changed towards more subtlety. Beyond the specific minerality issue investigated in this paper, the methodology (CLV approach used in conjunction with renormalized Markov associativities) demonstrates its ability to generate informative clusters of textual networks, highlighting the cores of prototypical

    Crowdsourcing is the primary means to generate training data at scale, and when combined with sophisticated machine learning algorithms, crowdsourcing is an enabler for a variety of emergent automated applications impacting all spheres of our lives. This paper surveys the emerging field of formally reasoning about and optimizing open-ended crowdsourcing, a popular and crucially important, but severely understudied class of crowdsourcing—the next frontier in crowdsourced data management. The underlying challenges include distilling the right answer when none of the workers agree with each other, teasing apart the various perspectives adopted by workers when answering tasks, and effectively selecting between the many open-ended operators appropriate for a problem. We describe the approaches that we’ve found to be effective for open-ended crowdsourcing, drawing from our experiences in this space. PMID:28951893

  11. Semi-automated categorization of open-ended questions

    2016-08-01

    Full Text Available Text data from open-ended questions in surveys are difficult to analyze and are frequently ignored. Yet open-ended questions are important because they do not constrain respondents’ answer choices. Where open-ended questions are necessary, sometimes multiple human coders hand-code answers into one of several categories. At the same time, computer scientists have made impressive advances in text mining that may allow automation of such coding. Automated algorithms do not achieve an overall accuracy high enough to entirely replace humans. We categorize open-ended questions soliciting narrative responses using text mining for easy-to-categorize answers and humans for the remainder using expected accuracies to guide the choice of the threshold delineating between “easy” and “hard”. Employing multinomial boosting avoids the common practice of converting machine learning “confidence scores” into pseudo-probabilities. This approach is illustrated with examples from open-ended questions related to respondents’ advice to a patient in a hypothetical dilemma, a follow-up probe related to respondents’ perception of disclosure/privacy risk, and from a question on reasons for quitting smoking from a follow-up survey from the Ontario Smoker’s Helpline. Targeting 80% combined accuracy, we found that 54%-80% of the data could be categorized automatically in research surveys.

    Quality in higher education is widely controlled through surveys asking students to evaluate teaching. However, control of quality does not necessarily lead to enhancement of quality. Drawing on accounting research and a case study, a measurement-based and open-ended quality control system...... emphasising quality enhancement is suggested. The case shows how interactive use of performance measurement can lead to more engaged and enabling dialogue amongst involved actors concerning quality enhancement, however institutionalised beliefs regarding course evaluation systems makes a change challenging...

    Conceptual design studies on fusion reactors based upon open-ended confinement schemes, such as the tandem mirror and rf plugged cusp, have been carried out in Japan. These studies may be classified into two categories: near-term devices (Fusion Engineering Test Facility), and long-term fusion power recators. In the first category, a two-component cusp neutron source was proposed. In the second category, the GAMMA-R, a tandem-mirror power reactor, and the RFC-R, an axisymetric mirror and cusp, reactor studies are being conducted at the University of Tsukuba and the Institute of Plasma Physics. Mirror Fusion Engineering Facility parameters and a schematic are shown. The GAMMA-R central-cell design schematic is also shown

    2011-07-01

    Full Text Available Quantitative Literacy (QL has been described as the skill set an individual uses when interacting with the world in a quantitative manner. A necessary component of this interaction is communication. To this end, assessments of QL have included open-ended items as a means of including communicative aspects of QL. The present study sought to examine whether such open-ended items typically measured aspects of quantitative communication, as compared to mathematical communication, or mathematical skills. We focused on public-released items and rubrics from four of the most widely referenced assessments: the Third International Mathematics and Science Study (TIMSS-95: the National Adult Literacy Survey (NALS; now the National Assessment of Adult Literacy, NAAL in 1985 and 1992, the International Adult Literacy Skills (IALS beginning in 1994; and the Program for International Student Assessment (PISA beginning in 2000. We found that open-ended item rubrics in these QL assessments showed a strong tendency to assess answer-only responses. Therefore, while some open-ended items may have required certain levels of quantitative reasoning to find a solution, it is the solution rather than the reasoning that was often assessed.

    2008-12-01

    Motivated by the need to support language-based communication between robots and their human users, as well as grounded symbolic reasoning, this paper presents a learning architecture that can be used by robotic agents for long-term and open-ended category acquisition. To be more adaptive and to improve learning performance as well as memory usage, this learning architecture includes a metacognitive processing component. Multiple object representations and multiple classifiers and classifier combinations are used. At the object level, the main similarity measure is based on a multi-resolution matching algorithm. Categories are represented as sets of known instances. In this instance-based approach, storing and forgetting rules optimise memory usage. Classifier combinations are based on majority voting and the Dempster-Shafer evidence theory. All learning computations are carried out during the normal execution of the agent, which allows continuous monitoring of the performance of the different classifiers. The measured classification successes of the individual classifiers support an attentional selection mechanism, through which classifier combinations are dynamically reconfigured and a specific classifier is chosen to predict the category of a new unseen object. A simple physical agent, incorporating these learning capabilities, is used to test the approach. A long-term experiment was carried out having in mind the open-ended nature of category learning. With the help of a human mediator, the agent incrementally learned 68 categories of real-world objects visually perceivable through an inexpensive camera. Various aspects of the approach are evaluated through systematic experiments.

    Efficient mass transport through porous networks is essential for achieving rapid response times in sensing applications utilizing porous materials. In this work, we show that open-ended porous membranes can overcome diffusion challenges experienced by closed-ended porous materials in a microfluidic environment. A theoretical model including both transport and reaction kinetics is employed to study the influence of flow velocity, bulk analyte concentration, analyte diffusivity, and adsorption rate on the performance of open-ended and closed-ended porous sensors integrated with flow cells. The analysis shows that open-ended pores enable analyte flow through the pores and greatly reduce the response time and analyte consumption for detecting large molecules with slow diffusivities compared with closed-ended pores for which analytes largely flow over the pores. Experimental confirmation of the results was carried out with open- and closed-ended porous silicon (PSi) microcavities fabricated in flow-through and flow-over sensor configurations, respectively. The adsorption behavior of small analytes onto the inner surfaces of closed-ended and open-ended PSi membrane microcavities was similar. However, for large analytes, PSi membranes in a flow-through scheme showed significant improvement in response times due to more efficient convective transport of analytes. The experimental results and theoretical analysis provide quantitative estimates of the benefits offered by open-ended porous membranes for different analyte systems.

    Post, R.F.; Ryutov, D.D.

    1995-05-01

    Magnetic confinement systems that use externally generated magnetic fields can be divided topologically into two classes: ''closed'' and 'open''. The tokamak, the stellarator, and the reversed-field-pinch approaches are representatives of the first category, while mirror-based systems and their variants are of the second category. While the recent thrust of magnetic fusion research, with its emphasis on the tokamak, has been concentrated on closed geometry, there are significant reasons for the continued pursuit of research into open-ended systems. The paper discusses these reasons, reviews the history and the present status of open-ended systems, and suggests some future directions for the research

  12. A Computational Analysis Model for Open-ended Cognitions

    Science.gov (United States)

    Morita, Junya; Miwa, Kazuhisa

    In this paper, we propose a novel usage for computational cognitive models. In cognitive science, computational models have played a critical role of theories for human cognitions. Many computational models have simulated results of controlled psychological experiments successfully. However, there have been only a few attempts to apply the models to complex realistic phenomena. We call such a situation ``open-ended situation''. In this study, MAC/FAC (``many are called, but few are chosen''), proposed by [Forbus 95], that models two stages of analogical reasoning was applied to our open-ended psychological experiment. In our experiment, subjects were presented a cue story, and retrieved cases that had been learned in their everyday life. Following this, they rated inferential soundness (goodness as analogy) of each retrieved case. For each retrieved case, we computed two kinds of similarity scores (content vectors/structural evaluation scores) using the algorithms of the MAC/FAC. As a result, the computed content vectors explained the overall retrieval of cases well, whereas the structural evaluation scores had a strong relation to the rated scores. These results support the MAC/FAC's theoretical assumption - different similarities are involved on the two stages of analogical reasoning. Our study is an attempt to use a computational model as an analysis device for open-ended human cognitions.

  14. Vortex formation at the open end of an acoustic waveguide

    Martinez Del Rio, Leon; Rendon, Pablo L.; Malaga, Carlos; Zenit, Roberto

    2017-11-01

    For high enough levels of acoustic pressure inside a cylindrical tube, a nonlinear mechanism is responsible for the formation of annular vortices at the open end of the tube, which results in energy loss. Higher sound pressure levels in the tube lead, in turn, to larger values of the acoustic velocity at the exit, and thus to higher Reynolds numbers. It has been observed [Buick et al., 2011] that, provided the magnitude of the acoustic velocity is large enough, two nonlinear regimes are possible: in the first regime, the vorticity appears only in the immediate vicinity of the tube; for higher velocities, vortex rings are formed at the open end of the tube and are advected outwards. We use a Lattice Boltzmann Method (LBM) to simulate the velocity and the pressure fields at the exit of the tube in 3D, with Reynolds numbers based on the acoustic boundary layer thickness 18 >Rδ > 1.8 . We also conduct experiments with phase-locked particle image velocimetry (PL-PIV) 2D within a range of 25.5 >Rδ > 10.2 . Experimental and numerical results are compared for a range of Womersley numbers. The effects of varying both the tube geometry and the end shape are addressed.

    The sequence used for collecting quantitative and qualitative data in concurrent mixed-methods research may influence participants' responses. Empirical evidence is needed to determine if the order of data collection in concurrent mixed methods research biases participants' responses to closed and open-ended questions. To examine the influence of the quantitative-qualitative sequence on responses to closed and open-ended questions when assessing the same variables or aspects of a phenomenon simultaneously within the same study phase. A descriptive cross-sectional, concurrent mixed-methods design was used to collect quantitative (survey) and qualitative (interview) data. The setting was a large multi-site health care centre in Canada. A convenience sample of 50 registered nurses was selected and participated in the study. Participants were randomly assigned to one of two sequences for data collection, quantitative-qualitative or qualitative-quantitative. Independent t-tests were performed to compare the two groups' responses to the survey items. Directed content analysis was used to compare the participants' responses to the interview questions. The sequence of data collection did not greatly affect the participants' responses to the closed-ended questions (survey items) or the open-ended questions (interview questions). The sequencing of data collection, when using both survey and semi-structured interviews, may not bias participants' responses to closed or open-ended questions. Additional research is required to confirm these findings. Copyright © 2011 Elsevier Ltd. All rights reserved.

  16. Discontinuous phase transition in an open-ended Naming Game

    International Nuclear Information System (INIS)

    Crokidakis, Nuno; Brigatti, Edgardo

    2015-01-01

    In this work we study on a 2D square lattice a recent version of the Naming Game, an agent-based model used for describing the emergence of linguistic structures. The system is open-ended and agents can invent new words throughout the evolution of the game, picking them up from a pool characterised by a Gaussian distribution with standard deviation σ. The model displays a nonequilibrium phase transition at a critical point σ c  ≈ 25.6, which separates an absorbing consensus state from an active fragmented state where agents continuously exchange different words. The finite-size scaling analysis of our simulations strongly suggests that the phase transition is discontinuous. (paper)

    2013-10-23

    Vocal learning in birds is typically restricted to a sensitive period early in life, with the few exceptions reported in songbirds and parrots. Here, we present evidence of open-ended vocal learning in a hummingbird, the third avian group with vocal learning. We studied vocalizations at four leks of the long-billed hermit Phaethornis longirostris during a four-year period. Individuals produce a single song repertoire, although several song-types can coexist at a single lek. We found that nine of 49 birds recorded on multiple days (18%) changed their song-type between consecutive recordings. Three of these birds replaced song-types twice. Moreover, the earliest estimated age when song replacement occurred ranged from 186 to 547 days (mean = 307 days) and all nine birds who replaced song-types produced a crystallized song before replacement. The findings indicate that song-type replacement is distinct from an initial early learning sensitive period. As half of lekking males do not survive past the first year of life in this species, song learning may well extend throughout the lifespan. This behaviour would be convergent to vocal learning programmes found in parrots and songbirds.

  19. Open-Ended Coaxial Dielectric Probe Effective Penetration Depth Determination

    2016-01-01

    We have performed a series of experiments which demonstrate the effect of open-ended coaxial diameter on the depth of penetration. We used a two layer configuration of a liquid and movable cylindrical piece of either Teflon or acrylic. The technique accurately demonstrates the depth in a sample for which a given probe diameter provides a reasonable measure of the bulk dielectric properties for a heterogeneous volume. In addition we have developed a technique for determining the effective depth for a given probe diameter size. Using a set of simulations mimicking four 50 Ω coaxial cable diameters, we demonstrate that the penetration depth in both water and saline has a clear dependence on probe diameter but is remarkably uniform over frequency and with respect to the intervening liquid permittivity. Two different 50 Ω commercial probes were similarly tested and confirm these observations. This result has significant implications to a range of dielectric measurements, most notably in the area of tissue property studies. PMID:27346890

    The detection of freeze/thaw (F/T) physical state of soil is one of the main objectives of the SMAP mission as well as one of the secondary objectives of the SMOS mission. Annual F/T cycles have substantial impacts on surface energy budgets, permafrost conditions, as well as forest water and carbon dynamics. It has been shown that spaceborne L-band passive radiometry is a promising tool to monitor F/T due to the substantial differences between the permittivity of water and ice at these frequencies. However, the decoupling of the signal between soil and vegetation components remains challenging for all microwave remote sensing applications at various spatial scales. Radiative transfer models in the microwave domain are generally poorly parameterized to consider the non-negligible contribution of vegetation. The main objective of this research is to assess the skill of a recently developed Open-Ended Coaxial Probe (OECP) to measure the complex microwave permittivity of vegetation and soils and to derive a relation between the impact of vegetation on the microwave signal and the vegetation permittivity that could serve as a validation tool for soil models especially in frozen state. Results show that the OECP is a suitable tool to infer the radial profile of the complex permittivity in L-band of trees. A clear distinction can be made between the dielectric characterization of the sapwood where the permittivity is high because of the high permittivity of water but decrease with depth, and the heartwood where the permittivity is low and relatively constant. The seasonal cycle of the F/T state of the vegetation can also be observed since it is strongly correlated with the permittivity of the wood. The permittivity of a tree over the winter season is very low and homogenous since the permittivity of ice is significantly lower than water and the sap flow is negligible. The fluctuation of the frozen and thawed permittivity for different tree species was evaluated, focusing

    2015-05-01

    Teachers in many parts of the world are mandated reporters of child abuse and maltreatment but very little is known concerning how they question children in suspicious circumstances. Teachers (n=36), who had previously participated in a mock interview scenario designed to characterize their baseline use of various question-types when attempting to elicit sensitive information from children, were given online training in choosing effective questions. They engaged in simulated interviews with a virtual avatar several times in one week and then participated in a mock interview scenario. The amount and proportion of open-ended questions they used increased dramatically after training. The overall number of questions, and amount and proportions of specific and leading questions decreased. In particular, large decreases were observed in more risky yes-no and other forced-choice questions. Given that most teachers may feel the need to ask a child about an ambiguous situation at some point during their careers it is worthwhile to incorporate practice asking effective questions into their training, and the present research suggests that an e-learning format is effective. Additionally, effective questions encourage the development of narrative competence, and we discuss how teachers might include open-ended questions during regular classroom learning.

  5. Learning autonomy in two or three steps: linking open-ended development, authority, and agency to motivation.

    2013-01-01

    In this paper we connect open-ended development, authority, agency, and motivation through (1) an analysis of the demands of existing in a complex world and (2) environmental appraisal in terms of affordance content and the complexity to select appropriate behavior. We do this by identifying a coherent core from a wide range of contributing fields. Open-ended development is a structured three-step process in which the agent first learns to master the body and then aims to make the mind into a reliable tool. Preconditioned on success in step two, step three aims to effectively co-create an optimal living environment. We argue that these steps correspond to right-left-right hemispheric dominance, where the left hemisphere specializes in control and the right hemisphere in exploration. Control (e.g., problem solving) requires a closed and stable world that must be maintained by external authorities or, in step three, by the right hemisphere acting as internal authority. The three-step progression therefore corresponds to increasing autonomy and agency. Depending on how we appraise the environment, we formulate four qualitatively different motivational states: submission, control, exploration, and consolidation. Each of these four motivational states has associated reward signals of which the last three-successful control, discovery of novelty, and establishing new relations-form an open-ended development loop that, the more it is executed, helps the agent to become progressively more agentic and more able to co-create a pleasant-to-live-in world. We conclude that for autonomy to arise, the agent must exist in a (broad) transition region between order and disorder in which both danger and opportunity (and with that open-ended development and motivation) are defined. We conclude that a research agenda for artificial cognitive system research should include open-ended development through intrinsic motivations and ascribing more prominence to right hemispheric strengths.

  10. Survey of state legislative programs that include passive solar energy

    Energy Technology Data Exchange (ETDEWEB)

    Weiss, S

    1979-06-01

    This report surveys and evaluates state-level solar-incentive programs, including passive solar energy. The range of programs examined focuses on financial and legal incentives designed to speed the implementation of solar heating, cooling, and hot water systems. They have been evaluated by probing the wording of the incentive legislation and by interviewing state program administrators in each state to determine: (1) the extent, if any, of passive inclusion in solar-incentive programs, and (2) the level of success that various implementation techniques have achieved for encouraging passive solar designs as opposed to the more-commonly-understood active systems. Because no states have initiated incentive legislation designed exclusively to encourage passive solar techniques, it has been essential to determine whether legislative programs explicitly or implicitly include passive solar or if they explicitly exclude it.

    Alcohol's function as a regulator of emotions has long been denoted in figures of speech, most famously 'in vino, veritas' (in wine, truth). In contrast, we ask whether an individual's self-reported alcohol consumption and related attitudes can be correlated with the words they use to write about alcohol. Participants completed an open-ended essay as part of a survey on alcohol attitudes and behaviors. We used a computerized technique, the Meaning Extraction Method, to summarize the responses into thematic tropes, and correlated these with quantitative measurements of demographics, attitudes and behaviors. Participants were recruited using a random population postal survey in the UK (n=1001). Principal components analysis identified regular co-occurring words, to locate themes in the responses. Seven themes were identified that corresponded to both negative and positive aspects of alcohol consumption ranging from concern for the influence of alcohol on others (e.g., children and family) to participants' own enjoyment of alcohol (e.g., social drinking). Small but significant correlations suggested a relationship between the essay responses and individual consumption patterns and attitudes. Copyright © 2013 Elsevier Ltd. All rights reserved.

    We present the theory and implementation of an open-ended framework for electric response properties at the level of Hartree-Fock and Kohn-Sham density functional theory that includes effects from the molecular environment modeled by the polarizable embedding (PE) model. With this new state-of-the-art multiscale functionality, electric response properties to any order can be calculated for molecules embedded in polarizable atomistic molecular environments ranging from solvents to complex heterogeneous macromolecules such as proteins. In addition, environmental effects on multiphoton absorption (MPA) properties can be studied by evaluating single residues of the response functions. The PE approach includes mutual polarization effects between the quantum and classical parts of the system through induced dipoles that are determined self-consistently with respect to the electronic density. The applicability of our approach is demonstrated by calculating MPA strengths up to four-photon absorption for the green fluorescent protein. We show how the size of the quantum region, as well as the treatment of the border between the quantum and classical regions, is crucial in order to obtain reliable MPA predictions.

    We describe the content and outcomes of the First Workshop on Open-Ended Evolution: Recent Progress and Future Milestones (OEE1), held during the ECAL 2015 conference at the University of York, UK, in July 2015. We briefly summarize the content of the workshop's talks, and identify the main themes that emerged from the open discussions. Two important conclusions from the discussions are: (1) the idea of pluralism about OEE-it seems clear that there is more than one interesting and important kind of OEE; and (2) the importance of distinguishing observable behavioral hallmarks of systems undergoing OEE from hypothesized underlying mechanisms that explain why a system exhibits those hallmarks. We summarize the different hallmarks and mechanisms discussed during the workshop, and list the specific systems that were highlighted with respect to particular hallmarks and mechanisms. We conclude by identifying some of the most important open research questions about OEE that are apparent in light of the discussions. The York workshop provides a foundation for a follow-up OEE2 workshop taking place at the ALIFE XV conference in Cancún, Mexico, in July 2016.

Rich play can be described as ongoing play that changes over time in character, form and nature. This paper elaborates on our initial insights on how rules and goals develop from interaction opportunities of the system, based on two pilot studies with an interactive play environment for open-ended play. Furthermore we will discuss the roles of feedback and adaptation mechanisms in the environment. Those system properties will change the interaction opportunities to match with the current situation in the play environment and to support richness in play.

    2016-12-21

    The study of high-order absorption properties of molecules is a field of growing importance. Quantum-chemical studies can help design chromophores with desirable characteristics. Given that most experiments are performed in solution, it is important to devise a cost-effective strategy to include solvation effects in quantum-chemical studies of these properties. We here present an open-ended formulation of self-consistent field (SCF) response theory for a molecular solute coupled to a polarizable continuum model (PCM) description of the solvent. Our formulation relies on the open-ended, density matrix-based quasienergy formulation of SCF response theory of Thorvaldsen, et al., [J. Chem. Phys., 2008, 129, 214108] and the variational formulation of the PCM, as presented by Lipparini et al., [J. Chem. Phys., 2010, 133, 014106]. Within the PCM approach to solvation, the mutual solute-solvent polarization is represented by means of an apparent surface charge (ASC) spread over the molecular cavity defining the solute-solvent boundary. In the variational formulation, the ASC is an independent, variational degree of freedom. This allows us to formulate response theory for molecular solutes in the fixed-cavity approximation up to arbitrary order and with arbitrary perturbation operators. For electric dipole perturbations, pole and residue analyses of the response functions naturally lead to the identification of excitation energies and transition moments. We document the implementation of this approach in the Dalton program package using a recently developed open-ended response code and the PCMSolver libraries and present results for one-, two-, three-, four- and five-photon absorption processes of three small molecules in solution.

Open-ended approach strongly supports the use of computer software in learning, because the goal of open-ended learning is to help developing creative activities and mathematical mindset of students through problem solving simultaneously. In other words, creative activities and mathematical mindset of students should be developed as much as possible in accordance with the ability of spatial ability of each student. Spatial ability is the ability of students in constructing and representing geometry models. This study aims to determine the improvement of spatial ability of junior high school students who obtained learning with open-ended approach aided by Cabri 3D. It adopted a quasi-experimental method with the non-randomized control group pretest-posttest design and the 2×3 factorial model. The instrument of the study is spatial ability test. Based on analysis of the data, it is found that the improvement of spatial ability of students who received open-ended learning aided by Cabri 3D was greater than students who received expository learning, both as a whole and based on the categories of students’ initial mathematical ability.

    Full Text Available Resolution of high intensity focused ultrasound (HIFU focusing is limited by the wave diffraction. We have developed a spherical cavity transducer with two open ends to improve the focusing precision without sacrificing the acoustic intensity (App Phys Lett 2013; 102: 204102. This work aims to theoretically and experimentally investigate the frequency dependence of the acoustic field generated from the spherical cavity transducer with two open ends. The device emits high intensity ultrasound at the frequency ranging from 420 to 470 kHz, and the acoustic field is measured by a fiber optic probe hydrophone. The measured results shows that the spherical cavity transducer provides high acoustic intensity for HIFU treatment only in its resonant modes, and a series of resonant frequencies can be choosen. Furthermore, a finite element model is developed to discuss the frequency dependence of the acoustic field. The numerical simulations coincide well with the measured results.

  13. The Solving of Problems in Chemistry: the more open-ended problems

    Reid, Norman; Yang, Mei-Jung

    2002-01-01

    Most problem solving in chemistry tends to be algorithmic in nature, while problems in life tend to be very open ended. This paper offers a simple classification of problems and seeks to explore the many factors which may be important in the successful solving of problems. It considers the place of procedures and algorithms. It analyses the role of long-term memory, not only in terms of what is known, but how that knowledge was acquired. It notes the great importance of the limitations of working memory space and the importance of confidence which comes from experience. Finally, various psychological factors are discussed. This paper argues that solving open-ended problems is extremely important in education and that offering learners experience of this in a group work context is a helpful way forward.

    2012-01-01

    Full Text Available This article presents a reflexive analysis of two transcripts of an open-ended interview and argues for transparency in transcribing processes and outcomes. By analyzing ways in which a researcher's theories become consequential in producing and using transcripts of an open-ended interview, this paper makes visible the importance of examining and presenting theoretical bases of transcribing decisions. While scholars across disciplines have argued that transcribing is a theoretically laden process (GREEN, FRANQUIZ & DIXON, 1997; KVALE & BRINKMAN, 2009, few have engaged in reflexive analyses of the data history to demonstrate the consequences particular theoretical and methodological approaches pose in producing knowledge claims and inciting dialogues across traditions. The article demonstrates how theory-method-claim relationships in transcribing influence research transparency and warrantability. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1201146

    2018-01-01

    Is undecidability a requirement for open-ended evolution (OEE)? Using methods derived from algorithmic complexity theory, we propose robust computational definitions of open-ended evolution and the adaptability of computable dynamical systems. Within this framework, we show that decidability imposes absolute limits on the stable growth of complexity in computable dynamical systems. Conversely, systems that exhibit (strong) open-ended evolution must be undecidable, establishing undecidability as a requirement for such systems. Complexity is assessed in terms of three measures: sophistication, coarse sophistication, and busy beaver logical depth. These three complexity measures assign low complexity values to random (incompressible) objects. As time grows, the stated complexity measures allow for the existence of complex states during the evolution of a computable dynamical system. We show, however, that finding these states involves undecidable computations. We conjecture that for similar complexity measures that assign low complexity values, decidability imposes comparable limits on the stable growth of complexity, and that such behavior is necessary for nontrivial evolutionary systems. We show that the undecidability of adapted states imposes novel and unpredictable behavior on the individuals or populations being modeled. Such behavior is irreducible. Finally, we offer an example of a system, first proposed by Chaitin, that exhibits strong OEE.

    This study aims to find out students metacognition difficulty during solving open-ended problem in mathematics. It focuses on analysing the metacognition difficulty of students with visual-spatial intelligence in solving open-ended problem. A qualitative research with case study strategy is used in this study. Data in the form of visual-spatial intelligence test result and recorded interview during solving open-ended problems were analysed qualitatively. The results show that: (1) students with high visual-spatial intelligence have no difficulty on each metacognition aspects, (2) students with medium visual-spatial intelligence have difficulty on knowledge aspect on strategy and cognitive tasks, (3) students with low visual-spatial intelligence have difficulty on three metacognition aspects, namely knowledge on strategy, cognitive tasks and self-knowledge. Even though, several researches about metacognition process and metacognition literature recommended the steps to know the characteristics. It is still important to discuss that the difficulties of metacognitive is happened because of several factors, one of which on the characteristics of student’ visual-spatial intelligence. Therefore, it is really important for mathematics educators to consider and pay more attention toward students’ visual-spatial intelligence and metacognition difficulty in designing better mathematics learning.

  20. Determining the Response Behaviors of Middle School Students for Open-Ended Questions

    2017-04-01

    Full Text Available When the literature for measurement and evaluation in education is reviewed, research related to student achievement are mainly outcome-oriented rather than process-oriented. Researchers pay attention to the responses that a student constructs or chooses, and ignore the cognitive processes that forces students to construct or choose that specific response. Recognizing the cognitive processes a student uses in responding to a question affects the item construction process and psychometric audit on items. Response behavior is a result of a cognitive process used to respond to a question and is accepted as an indicator of student cognitive competence. This study aims to determine the students’ response behaviors for open-ended questions. The study group consisted of 70 students from the 5th grade studying during the 2015-2016 education year spring term in the Cankaya and Mamak districts of Ankara province, Turkey. An authentic achievement test which consisted of eight open-ended questions is used as the data collection tool. Students are asked to write in detail how they construct their response in their mind in the blank space set aside after each question. Data is analyzed via grouping students’ response behaviors and expert opinions. Research findings revealed that students perform 14 different response behaviors for open-ended questions. These behaviors are themed as responses constructed directly from the text, responses constructed by interpreting the text, and responses constructed by linking real life and the text.

  3. Toward an Open-Ended BCI: A User-Centered Coadaptive Design.

    Science.gov (United States)

    Dhindsa, Kiret; Carcone, Dean; Becker, Suzanna

    2017-10-01

    Brain-computer interfaces (BCIs) allow users to control a device by interpreting their brain activity. For simplicity, these devices are designed to be operated by purposefully modulating specific predetermined neurophysiological signals, such as the sensorimotor rhythm. However, the ability to modulate a given neurophysiological signal is highly variable across individuals, contributing to the inconsistent performance of BCIs for different users. These differences suggest that individuals who experience poor BCI performance with one class of brain signals might have good results with another. In order to take advantage of individual abilities as they relate to BCI control, we need to move beyond the current approaches. In this letter, we explore a new BCI design aimed at a more individualized and user-focused experience, which we call open-ended BCI. Individual users were given the freedom to discover their own mental strategies as opposed to being trained to modulate a given brain signal. They then underwent multiple coadaptive training sessions with the BCI. Our first open-ended BCI performed similarly to comparable BCIs while accommodating a wider variety of mental strategies without a priori knowledge of the specific brain signals any individual might use. Post hoc analysis revealed individual differences in terms of which sensory modality yielded optimal performance. We found a large and significant effect of individual differences in background training and expertise, such as in musical training, on BCI performance. Future research should be focused on finding more generalized solutions to user training and brain state decoding methods to fully utilize the abilities of different individuals in an open-ended BCI. Accounting for each individual's areas of expertise could have important implications on BCI training and BCI application design.

    Full Text Available In this paper the problem of radiation from the open end of a semi-infinite circular metallic waveguide with perfectly conducting walls and a thin internal low-conducting metal coating is considered. Electromagnetic fields are generated by the ultrarelativistic point charge moving along the axis of the waveguide. The far fields of radiation are obtained using the near-field to far-field recovery technique. The technique is extended for the nonmonochromatic waves. It is shown that the radiation has a narrow-band and narrow-directional character.

    2018-01-01

    Feedback deals with giving information to students related to their task which is done through score of their achievement, reaction, and comments. Considering its hierarchy, task difficulty level consists of low, middle and high levels. The difficulty level of open-ended questions is middle to high. Open-ended question is a good way to train students’ knowledge. This research is a descriptive research which aims at describing teacher’s learning management, students’ activities, students’ learning achievement, and students’ responses in mathematic learning using OEQGF. The subject was a teacher of mathematics who teaches eighth graders, and students themselves. The research design used is one shot case study. The result shows that: management learning has been very well implemented by the teacher; every students’ activity has been carried out by students; the students’ learning achievement have reached the criteria of completeness, and the students’ responses can be considered as positive. Therefore, it can be concluded that mathematic learning using OEQGF is effective.

    Critical thinking plays an important role for students in solving open-ended problems. This research aims at describing student’s critical thinking in solving open-ended problems based on Keirsey’s personality types, namely rational, idealist, guardian, and artisan. Four students, with the higher rank in the mathematics’ test and representing each type of Keirsey personality, were selected as the research subjects. The data were collected from the geometry problem and interviews. The student’s critical thinking is described based on the FRISCO criteria. The result underlines that rational and idealist students fulfilled all FRISCO criteria, and but not for guardian and artisan students. Related to the inference criteria, guardian and artisan students could not make reasonable conclusions and connect the concepts. Related to the reason of criteria, rational student performed critical thinking by providing logical reason that supported his strategy to solve the problem. In contrast, the idealist student provided subjective reason. This results suggest that teachers should frequently train the students’ logical thinkingin every lesson and activity to develop student’s critical thinking and take the student’s personality character into account, especially for guardian and artisan students.

    Williams, Shawn

    2016-01-01

    Job stress and emotional exhaustion have been shown to have a negative impact on the helping professional. The development and causal relations of job stress and emotional exhaustion are rather unclear in the chiropractic profession. The objective of this study is to understand the main sources of occupational stress and emotional exhaustion among doctors of chiropractic. Analysis of the written responses to web-based open-ended questionnaire was performed using an interpretive research methodology. Additionally, cross tabulation and Chi square statistical tests were conducted to match and couple the demographic data with the categorical themes. Fourteen professional stress categories emerged from the 970 completed surveys. "Managed Care Organization regulation", "Managed Care reimbursement" and "Scope of Practice Issues" were the most common stressors that negatively influenced chiropractors' professional and personal lives. The results of the categorical analysis suggests that age, marital status, number of years in practice and location of practice may have an influence on the category of stress reported by chiropractors. The qualitative approach revealed common, conventional and culture-specific job stressors in doctors of chiropractic. Notably, these findings suggest an association between third-party payer influences (increased regulation/decreased reimbursement) with that of increased job stress. Further research will be undertaken to refine the stress and satisfaction parameters and address stress interventions.

    2016-04-01

    This paper presents the results of an experimental teaching carried out on 12-year-old students. An open-ended task was given to them and they had not been taught the algorithmic process leading to the solution. The formal solution to the problem refers to a system of two linear equations with two unknown quantities. In this mathematical activity, students worked cooperatively. They discussed their discoveries in groups of four and then presented their answers to the whole class developing a rich communication. This study describes the characteristic arguments that represent certain different forms of reasoning that emerged during the process of justifying the solutions of the problem. The findings of this research show that within an environment conducive to creativity, which encourages collaboration, exploration and sharing ideas, students can be engaged in developing multiple mathematical strategies, posing new questions, creating informal proofs, showing beauty and elegance and bringing out that problem solving is a powerful way of learning mathematics.

    Full Text Available Weblogs and life journals are popular forms of reflecting and reporting online about one's everyday life. In this article the author examines whether solicited online diaries can be used in qualitative research. She discusses advantages and disadvantages of the online research, diaries as a source of data, and narration as a method. The discussion is exemplified by the presentation of an online diary study conducted in two parts in the spring and autumn of 2009 with students from Tartu, Narva, and Tallinn, Estonia. This article shows the illuminating potential and richness of solicited online diaries applied in an open-ended, qualitative understanding as a way to investigate everyday life. At the same time, the main challenges are presented and discussed.

  17. Formal Definitions of Unbounded Evolution and Innovation Reveal Universal Mechanisms for Open-Ended Evolution in Dynamical Systems.

    Open-ended evolution (OEE) is relevant to a variety of biological, artificial and technological systems, but has been challenging to reproduce in silico. Most theoretical efforts focus on key aspects of open-ended evolution as it appears in biology. We recast the problem as a more general one in dynamical systems theory, providing simple criteria for open-ended evolution based on two hallmark features: unbounded evolution and innovation. We define unbounded evolution as patterns that are non-repeating within the expected Poincare recurrence time of an isolated system, and innovation as trajectories not observed in isolated systems. As a case study, we implement novel variants of cellular automata (CA) where the update rules are allowed to vary with time in three alternative ways. Each is capable of generating conditions for open-ended evolution, but vary in their ability to do so. We find that state-dependent dynamics, regarded as a hallmark of life, statistically out-performs other candidate mechanisms, and is the only mechanism to produce open-ended evolution in a scalable manner, essential to the notion of ongoing evolution. This analysis suggests a new framework for unifying mechanisms for generating OEE with features distinctive to life and its artifacts, with broad applicability to biological and artificial systems.

    There are numerous challenges in including patients in a core outcome set (COS) study, these can vary depending on the patient group. This study describes current efforts to include patients in the development of COS, with the aim of identifying areas for further improvement and study. Using the COMET database, corresponding authors of COS projects registered or published from 1 January 2013 to 2 February 2017 were invited via a personalised email to participate in a short online survey. The survey and emails were constructed to maximise the response rate by following the academic literature on enhancing survey responses. Personalised reminder emails were sent to non-responders. This survey explored the frequency of patient input in COS studies, who was involved, what methods were used and whether or not the COS development was international. One hundred and ninety-two COS developers were sent the survey. Responses were collected from 21 February 2017 until 7 May 2017. One hundred and forty-six unique developers responded, yielding a 76% response rate and data in relation to 195 unique COSs (as some developers had worked on multiple COSs). Of focus here are their responses regarding 162 COSs at the published, completed or ongoing stages of development. Inclusion of patient participants was indicated in 87% (141/162) of COSs in the published completed or ongoing stages and over 94% (65/69) of ongoing COS projects. Nearly half (65/135) of COSs included patient participants from two or more countries and 22% (30/135) included patient participants from five or more countries. The Delphi survey was reported as being used singularly or in combination with other methods in 85% (119/140) of projects. Almost a quarter (16/65) of ongoing studies reported using a combination of qualitative interviews, Delphi survey and consensus meeting. These findings indicated that the Delphi survey is the most popular method of facilitating patient participation, while the combination of

    Full Text Available As the importance of embodiment emerges for psychology, there is a need to advance methodology for measuring the dynamics of movement in an open-ended fashion. Such a tool should be versatile across contexts and track spontaneous and natural movement with minimal constraints. We test the feasibility of a method for measuring whole-body movement over time that attempts to meet this need. We use a motion capture system comprised of two Microsoft Kinect version 2.0 cameras and iPiSoft Motion Capture software, and compare its estimates of magnitude rotational velocity and whole-body movement complexity (multivariate multiscale sample entropy; MMSE to that of a gold standard motion capture system across a variety of movement sequences. The candidate system satisfactorily estimated the instantaneous velocity of 13 body segments in agreement with the gold standard system across movement sequences demonstrating initial feasibility of this process. Summary calculations of velocity by sequence and MMSE calculations were also in high agreement with the gold standard, crucially suggesting that the candidate system could pick up on the complex dynamics of movement over time. The candidate system was feasible and demonstrates preliminary validity for general use in the tracking of continuous human movement for clinical and experimental psychology. We also provide R code and sample data for the importing and processing of movement data exported from iPiSoft Motion Capture Studio.

    The steam generators of a double pool type liquid metal fast breeder reactor (LMFBR) are used in a large sodium pool which is formed between the primary vessel and the secondary vessel and accommodates the entire secondary heat transport system. Therefore, if there is a sodium-water reaction event in the steam generator, it becomes important to evaluate the pressure rises at the walls of the primary and secondary vessels as well as those at the other secondary components. An experimental study was performed, focusing on the propagation of the initial pressure spike of the-sodium-water reaction from the bottom end of the steam generator to the sodium pool. Pressure wave propagation from inside of a pipe to an open space through the pipe end was measured. Two kinds of pressure propagation media, water and air, ensured a wide range of experimental conditions. The experimental results revealed that the pressure attenuation at the open end of a pipe can be put in order using the concept of inertial length, and that the dimensionless inertial length, i.e., the inertial length divided by the half wave length of the pressure pulse, is proportional to the square of the dimensionless diameter. These results provide a prediction method for a pressure rise by the initial pressure spike in the secondary sodium pool of the Double Pool LMFBR

    Women in Nuclear-Korea (WINK) surveyed the public understanding on various energy resources in early September 2006 to offer the result for establishment of the nuclear communication policy. The reason why this survey includes other energy resources is because the previous works are only limited on nuclear energy, and also aimed to know the public's opinion on the present communication skill of nuclear energy for the public understanding. The present study is purposed of having data how public understands nuclear energy compared to other energies, such as fossil fuels, hydro power, and other sustainable energies. The data obtained from this survey have shown different results according to the responded group; age, gender, residential area, etc. Responded numbers are more than 2,000 of general public and university students. The survey result shows that nuclear understanding is more negative in women than in men, and is more negative in young than older age

    Nitrate (NO3 -) is an ergogenic nutritional supplement that is widely used to improve physical performance. However, the effectiveness of NO3 - supplementation has not been systematically investigated in individuals with different physical fitness levels. The present study analysed whether different fitness levels (non-athletes v. athletes or classification of performance levels), duration of the test used to measure performance (short v. long duration) and the test protocol (time trials v. open-ended tests v. graded-exercise tests) influence the effects of NO3 - supplementation on performance. This systematic review and meta-analysis was conducted and reported according to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. A systematic search of electronic databases, including PubMed, Web of Science, SPORTDiscus and ProQuest, was performed in August 2017. On the basis of the search and inclusion criteria, fifty-four and fifty-three placebo-controlled studies evaluating the effects of NO3 - supplementation on performance in humans were included in the systematic review and meta-analysis, respectively. NO3 - supplementation was ergogenic in non-athletes (mean effect size (ES) 0·25; 95 % CI 0·11, 0·38), particularly in evaluations of performance using long-duration open-ended tests (ES 0·47; 95 % CI 0·23, 0·71). In contrast, NO3 - supplementation did not enhance the performance of athletes (ES 0·04; 95 % CI -0·05, 0·15). After objectively classifying the participants into different performance levels, the frequency of trials showing ergogenic effects in individuals classified at lower levels was higher than that in individuals classified at higher levels. Thus, the present study indicates that dietary NO3 - supplementation improves physical performance in non-athletes, particularly during long-duration open-ended tests.

    This qualitative study examines membership processes in groups operating in an uncertain environment that prevents them from fully predefining new members' roles. I describe how nine elite high-end, cutting-edge culinary groups in the U.S. and Europe, ranging from innovative restaurants to culinary R&D groups, use negotiated joining-a previously undocumented process-to systematically construct and fill these emergent, open-ended roles. I show that negotiated joining is a consistently patterned, iterative process that begins with a role that both aspirant and target group explicitly understand to be provisional. This provisional role is then jointly modified and constructed by the aspirant and target group through repeated iterations of proposition, validation through trial and evaluation, and selective integration of validated role components. The initially provisional role stabilizes and the aspirant achieves membership if enough role components are validated; otherwise the negotiated joining process is abandoned. Negotiated joining allows the aspirant and target group to learn if a mutually desirable role is likely and, if so, to construct such a role. In addition, the provisional roles in negotiated joining can support absorptive capacity by allowing novel role components to enter target groups through aspirants' efforts to construct stable roles for themselves, while the internal adjustment involved in integrating newly validated role components can have the unintended side effect of supporting adaptation by providing opportunities for the groups to use these novel role components to modify their role structure and goals to suit a changing and uncertain environment. Negotiated joining thus reveals role ambiguity's hitherto unexamined beneficial consequences and provides a foundation for a contingency theory of new-member acquisition.

    Dielectric spectroscopy is a measurement technique to characterize the interaction between electromagnetic energy and macroscopic samples as a function of frequency. It is based on the measurement of complex permittivity plus conductivity and it has shown to be very useful to provide information about internal structure of matter. It has some advantages over others like optical or chemical analysis: it is very fast, easy to implement, requires little or no preparation of the sample, it can be non-destructive and/or minimally intrusive. In this paper the development of a dielectric spectroscopy system for the microwave frequency range (50 MHz-20 GHz), using an open-ended coaxial probe as sensor, is described. The complete system includes a vector network analyzer, a microwave coaxial cable, the probe, a sample holder and a computer to automate measurements and further data processing. This system has been used to measure some liquid and solid materials such as alcohol, water and Teflon. The real and imaginary parts of permittivity as function of frequency, for several sugarcane alcohol and deionised water mixtures, tequilas and Teflon samples are given. Measurement repeatability and accuracy considerations were taken and it was identified that uncertainty of reference standards and system repeatability are the most important error sources. Also, it was found that open-ended coaxial probe technique is appropriate for measuring not only liquids but also solid materials. Some of the obtained results were compared to those reported in literature and good convergence was observed.

    Full Text Available The present study investigated the extent to which an instructional framework of integrating strategy instruction (open-ended strategy and fill-in-the blanks strategy with motivation- support affected on reading result for young EFL learners. The central area of exploration included a comparison among three approaches to reading instruction: First, fill-in-the blanks strategy intervention; second, open-ended strategy intervention; and last, a control group which received the conventional reading strategies. The participants were sampled from amongst a group of seventy-seven pre-intermediate EFL learners in a language school in Tehran- Iran based on convenient sampling technique. For the sake of measurement, the researchers administered PET and CELT along with reading strategy based-test to quantify the participants’ current level of knowledge as well as the degree of achievement after treatment. For measurement’s sake, different types of tests such as PET, reading comprehension test (CELT, and reading strategy based- test were employed to quantify the participants’ current level of knowledge as well as the degree of achievement before and after instruction. The result of the present study indicated that the experimental groups had a significant improvement over the control group. Also, the level of learners’ reading engagement during classroom work mediated the instructional effects on reading outcomes. The results of this study can be to the benefit of both EFL and ESL teachers to teach reading comprehension using the student's critical mind as well as critical involvement in the reading tasks.

  16. A Possible Link between Supra-Second Open-Ended Timing Sensitivity and Obsessive-Compulsive Tendencies.

    One of the main characteristics of obsessive-compulsive disorder (OCD) is the persistent feeling of uncertainty, affecting many domains of actions and feelings. It was recently hypothesized that OCD uncertainty is related to attenuated access to internal states. As supra-second timing is associated with bodily and interoceptive awareness, we examined whether supra-second timing would be associated with OC tendencies. We measured supra-second (~9 s) and sub-second (~450 ms) timing along with control non-temporal perceptual tasks in a group of 60 university students. Supra-second timing was measured either with fixed criterion tasks requiring to temporally discriminate between two predefined fixed interval durations (9 vs. 9.9 s), or with an open-ended task requiring to discriminate between 9 s and longer intervals which were of varying durations that were not a priori known to the participants. The open-ended task employed an adaptive Bayesian procedure that efficiently estimated the duration difference required to discriminate 9 s from longer intervals. We also assessed symptoms of OCD, depression, and anxiety. Open-ended supra-second temporal sensitivity was correlated with OC tendencies, as predicted (even after controlling for depression and anxiety), whereas the other tasks were not. Higher OC tendencies were associated with lower timing sensitivity to 9 s intervals such that participants with higher OC tendency scores required longer interval differences to discriminate 9 s from longer intervals. While these results need to be substantiated in future research, they suggest that open-ended timing tasks, as those encountered in real-life (e.g., estimating how long it would take to complete a task), might be adversely affected in OCD.

    this course by cooperative take-home examinations. Students can discuss problems but their answers must be their own. This format allows more realistic and complex questions, although there are limits to the sophistication level that is achievable. Typical questions might include simulating the spectra that result for different pH and reagent concentrations when Cd2+, a chelating agent, and a complexation indicator are mixed. The question uses concepts that appeared in the first research paper exercise, but it requires reformulating it in a different context. Students report that the examinations are a reliable indicator of their comprehension and problem-solving skills. Correlation plots of cooperative vs. traditional examination results show no significant differences. Spreadsheets Spreadsheet programs have become recognized as very powerful devices for teaching in analytical chemistry because they provide the power required to tackle complex equilibria. At the same time, they are accessible to the unsophisticated student and they are important tools for a student to master. The spreadsheet programs are used in both lecture and laboratory contexts. Exercises are assigned that increase student proficiency gradually. Starting from a simple successive approximation exercise, students advance to creating species distribution functions (alpha-plots) for weak acids and then to modeling a titration curve including nonideality corrections. They also use computers for data acquisition in conjunction with a scanning spectrophotometer and data analysis of the overlapping spectra in a two-component mixture. Open-Ended Laboratory Projects The open-ended projects are the heart of the course. They have well-defined goals, but students are free to use their own creativity in reaching the goals. A listing of projects that have been used in the course is given in Table 1. The measurement of the pKa of an indicator and the development of a spectroscopic pH meter were projects used in

    To evaluate the radiation dose in routine multidetector computed tomography (MDCT) examinations in Italian population. This was a retrospective multicentre study included 5,668 patients from 65 radiology departments who had undergone common CT protocols: head, chest, abdomen, chest–abdomen–pelvis (CAP), spine and cardiac. Data included patient characteristics, CT parameters, volumetric CT dose index (CTDIvol) and dose length product (DLP) for each CT acquisition phase. Descriptive statistics were calculated, and a multi-regression analysis was used to outline the main factors affecting exposure. The 75th percentiles of CTDIvol (mGy) and DLP (mGy cm) for whole head were 69 mGy and 1,312 mGy cm, respectively; for chest, 15 mGy and 569 mGy cm; spine, 42 mGy and 888 mGy cm; cardiac, 7 mGy and 131 mGy cm for calcium score, and 61 mGy and 1,208 mGy cm for angiographic CT studies. High variability was present in the DLP of abdomen and CAP protocols, where multiphase examinations dominated (71 % and 73 % respectively): for abdomen, 18 mGy, with 555 and 920 mGy cm in abdomen and abdomen–pelvis acquisitions respectively; for CAP, 17 mGy, with 508, 850 and 1,200 mGy cm in abdomen, abdomen–pelvis and CAP acquisitions respectively. The results of this survey could help in the definition of updated diagnostic reference levels (DRL). • Radiation dose associated with multidetector CT (MDCT) is an important health issue. • This national survey assessed dose exposures of 5,668 patients undergoing MDCT. • Dose indices correlate with BMI, voltage, rotation time, pitch and tube current. • These results may contribute to an update of national diagnostic reference levels.

    Full Text Available Teaching and learning is fundamentally a two-way affair the teacher transferring knowledge and the learner making meaning from the knowledge. Teaching becomes complete when the learner acquires the knowledge transferred and applies it appropriately to real life situations. However in Ghana teaching and learning has undergone a lot of alteration coupled with both negative and positive effects. In Wa Polytechnic teaching and learning has seen little or no improvement with regards to information and communication Technology ICT making it difficult for students to acquire 21st century skills and be part of the digitally connected ecosystem. Active classroom participation and engagement information sharing communication collaboration coupled with large class sizes have been a problem for teachers and students in Wa Polytechnic hence the need to conduct a study to identify productive solutions that enhance students participation and engagement in the classroom. The study investigates the role of ICT in augmenting active participation and engagement of students in the classroom via open-ended response systems. The study was conducted using Educational Design Research EDR methods. A critical analysis was done by studying the responses of the respondents which identified three forms of students classroom participation and engagement verbal classroom participation non-verbal classroom participation and after classroom teaching and learning activities. Smart phones laptop tablet iPad and regular cellular phone were the predominant devices used by students for other purpose rather than teacher-led class activities. When students were made to actively participate in the classroom using the devices as open-ended response system students engagement and their ability to contribute during lectures appreciated comparatively. It was however evident that open-ended response system was effective tool to manage large class sizes as students who were timid could

    Full Text Available This study explores the effect of incorporating an Open-Ended Design Experience (OEDE into an undergraduate materials science laboratory taken by third-year mechanical engineering students. The focus of the OEDE was carbon fiber reinforced plastics and sandwich structures. The results indicate that the incorporation of OEDE’s in laboratory courses produces significant benefits in terms of student engagement, participation, and perception of competence. In addition, the OEDE was found to enhance students’ ability to apply related concepts as compared to non-OEDE lab activities. The authors conclude that the incorporation of OEDE’s can increase the effectiveness of engineering laboratory courses.

    It is rare that epidemiological surveys of patients with major trauma include both those admitted to the emergency department and those sent for medico-legal autopsy. The main aim of the present population-based study of major trauma was to examine the importance of medico-legal autopsy data. A new injury severity score (NISS)>15 or lethal outcome was used as criteria for major trauma and to identify patients at the emergency, anaesthesiology and forensic departments and/or being within the jurisdiction of the Malmö police authority and subjected to a medico-legal autopsy between 2011 and 2013. According to Swedish legislation all trauma related deaths should be reported to the police who refer these cases for medico-legal autopsy. Among the 174 individuals included, 92 (53%) died and 81 (47%) underwent medico-legal autopsy. One hundred twenty-six patients were primarily admitted to hospital and 48 died before admission to hospital and were sent directly for medico-legal autopsy. Forty-four in-hospital deaths occurred, of whom 33 (75%) were sent to medico-legal autopsy.

The high proportion of positive toxicological findings among fatalities examined at medico-legal autopsy implies that toxicology screening should be routine in major trauma patients, in order to improve treatment and prevention.

    To evaluate the radiation dose in routine multidetector computed tomography (MDCT) examinations in Italian population. This was a retrospective multicentre study included 5,668 patients from 65 radiology departments who had undergone common CT protocols: head, chest, abdomen, chest-abdomen-pelvis (CAP), spine and cardiac. Data included patient characteristics, CT parameters, volumetric CT dose index (CTDI{sub vol}) and dose length product (DLP) for each CT acquisition phase. Descriptive statistics were calculated, and a multi-regression analysis was used to outline the main factors affecting exposure. The 75th percentiles of CTDI{sub vol} (mGy) and DLP (mGy cm) for whole head were 69 mGy and 1,312 mGy cm, respectively; for chest, 15 mGy and 569 mGy cm; spine, 42 mGy and 888 mGy cm; cardiac, 7 mGy and 131 mGy cm for calcium score, and 61 mGy and 1,208 mGy cm for angiographic CT studies. High variability was present in the DLP of abdomen and CAP protocols, where multiphase examinations dominated (71 % and 73 % respectively): for abdomen, 18 mGy, with 555 and 920 mGy cm in abdomen and abdomen-pelvis acquisitions respectively; for CAP, 17 mGy, with 508, 850 and 1,200 mGy cm in abdomen, abdomen-pelvis and CAP acquisitions respectively. The results of this survey could help in the definition of updated diagnostic reference levels (DRL). (orig.)

    Full Text Available Rotor speed and twist per metres (tpm are two key parameters in open-end rotor spinning of cotton yarns. High spinning productivity can be obtained by keeping the rotor speed high and twist level as low as possible. However, too high rotor speed may result in yarn imperfections and too low twist level may result in lower tenacity yarns. This study aimed at optimising the multiple yarn characteristics in open-end rotor spinning using the Taguchi method and the grey relational analysis. Cotton yarn samples of 30 tex were produced on rotor spinning machine with different twist levels (i.e. 500, 550, 600 and 700 tpm at different rotor speeds (i.e. 70,000, 80,000, 90,000 and 100,000 rpm according to the Taguchi design of experiment. Optimal spinning process parameters were determined using the grey relational grade as the performance index. It was concluded that for the cotton fibres and yarn count used in this study, optimum properties of the yarns could be obtained at 90,000 rpm rotor speed and 700 tpm.

    We tried to analyze synthetically teachers' view points associated with health education and roles of school lunch in primary education. For this purpose, a survey using an open-ended questionnaire consisting of eight items relating to health education in the school curriculum was carried out in 100 teachers of ten public primary schools. Subjects were asked to describe their view regarding the following eight items: 1) health and physical guidance education, 2) school lunch guidance education, 3) pupils' attitude toward their own health and nutrition, 4) health education, 5) role of school lunch in education, 6) future subjects of health education, 7) class room lesson related to school lunch, 8) guidance in case of pupil with unbalanced dieting and food avoidance. Subjects described their own opinions on an open-ended questionnaire response sheet. Keywords in individual descriptions were selected, rearranged and classified into categories according to their own meanings, and each of the selected keywords were used as the dummy variable. To assess individual opinions synthetically, a principal component analysis was then applied to the variables collected through the teachers' descriptions, and four factors were extracted. The results were as follows. 1) Four factors obtained from the repeated principal component analysis were summarized as; roles of health education and school lunch program (the first principal component), cooperation with nurse-teachers and those in charge of lunch service (the second principal component), time allocation for health education in home-room activity and lunch time (the third principal component) and contents of health education and school lunch guidance and their future plan (the fourth principal component). 2) Teachers regarded the role of school lunch in primary education as providing daily supply of nutrients, teaching of table manners and building up friendships with classmates, health education and food and nutrition

    2017-12-01

    Findings conflict as to whether thin-ideal media affect women's body satisfaction. Meta-analyses of experimental studies reveal small or null effects, but many women endorse appearance-related media pressure in surveys. Using a novel approach, two samples of women (Ns=656, 770) were exposed to bikini models, fashion models, or control conditions and reported the effects of the images their body image. Many women reported the fashion/bikini models made them feel worse about their stomachs (57%, 64%), weight (50%, 56%), waist (50%, 56%), overall appearance (50%, 56%), muscle tone (46%, 52%), legs (45%, 48%), thighs (40%, 49%), buttocks (40%, 43%), and hips (40%, 46%). In contrast, few women (1-6%) reported negative effects of control images. In open-ended responses, approximately one-third of women explicitly described negative media effects on their body image. Findings revealed that many women perceive negative effects of thin-ideal media in the immediate aftermath of exposures in experimental settings. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The current study adopted a participant-informed, "bottom-up," qualitative approach to identifying perceived effects of pornography on the couple relationship. A large sample (N = 430) of men and women in heterosexual relationships in which pornography was used by at least one partner was recruited through online (e.g., Facebook, Twitter, etc.) and offline (e.g., newspapers, radio, etc.) sources. Participants responded to open-ended questions regarding perceived consequences of pornography use for each couple member and for their relationship in the context of an online survey. In the current sample of respondents, "no negative effects" was the most commonly reported impact of pornography use. Among remaining responses, positive perceived effects of pornography use on couple members and their relationship (e.g., improved sexual communication, more sexual experimentation, enhanced sexual comfort) were reported frequently; negative perceived effects of pornography (e.g., unrealistic expectations, decreased sexual interest in partner, increased insecurity) were also reported, albeit with considerably less frequency. The results of this work suggest new research directions that require more systematic attention.

    Full Text Available In 264 adult acute diarrhea cases with moderate course it was analyzed both symptoms and agents detected by different methods: in 91 cases (examined in the period of shigellosis high incidence level — by culture and serologic (specific antibodies detection methods to detect Shigella spp. and Salmonella spp. plus ELISA method to detect rotavirus antigen in feces; in 173 cases (examined in the period of shigellosis low incidence level — by above mentioned methods plus PCR based method. Data obtained in the period of shigellosis high incidence level have shown that there has been no significant difference in clinical scores (including colitis frequency between cases positive only for rotavirus antigen and those positive both for rotavirus antigen and Shigella spp. culture. That let suspect that acute diarrhea had been likely to be caused by association of rotavirus with any bacterial agent undetected by the methods used. PCR-based diagnostic method additionally used (in the period of shigellosis low incidence level resulted in detection of Campylobacter spp. accounted for campilobacteriosis as mono infection in 20,8% cases and as mixed infection (in association with other enteropatho-gens — in 4% cases. In cases with colitis the additional usage of PCR-based diagnostic method resulted in Salmonella spp. and Campylobacter spp. detection in every third case, Shigella spp. and agent association detection — in every fifth case. The target analysis of enteropathogens detected in 15 cases positive for rotavirus (examined in the period of shigellosis low incidence level has shown that in 6 of them there has been detected association of rotavirus with other agents predominantly bacterial ones (in 5 of 6 cases. So, the PCR method might be quite useful to broaden the spectrum of detected enteropathogens in adult acute diarrhea cases especially in those with colitis syndrome available.

    2015-01-01

    Full Text Available Numerical and experimental investigations of the flow and heat transfer in open-ended channel formed by the double skin façade have been undertaken in order to improve understanding of the phenomena and to apply it to passive cooling of building integrated photovoltaic systems. Both uniform heating and non-uniform heating configurations in which heat sources alternated with unheated zones on both skins were studied. Different periodic and asymmetric heating modes have been considered for the same aspect ratio 1/15 of wall distance to wall height and for periodicity 1/15 and 4/15 of heated/unheated zones and heat input, 220 W/m2. In computational study three dimensional transient LES simulation was carried out. It is shown that in comparison to uniformly heating configuration, non-uniformly heating configuration enhances both convective heat transfer and chimney effect.

    We introduce an algorithm to solve the secular equation that arises in the time independent multimode expansion of the quadratic vibronic coupling problem in parallel. The implementation can handle expansions of arbitrary length, with the open-ended character of the algorithm achieved through the use of fine grained parallelism to partition the trial vectors. The characteristics of the algorithm are discussed and its utility is illustrated by determining a model photoelectron spectrum of the ethoxy radical (C 2 H 5 O) using a vibronic expansion involving more than 1 billion vibronic basis states. This calculation also represents the first determination of a photoelectron spectrum obtained using a diabatic Hamiltonian obtained with a recently introduced ab initio surface reshaping procedure

    2013-09-01

    People with intellectual disabilities and their families are increasingly being asked to provide input into the services they receive. Under the aegis of the United Nation Convention of the Rights of Persons with Disabilities, support plans crucially depend on a participant's articulation of his or her preferences and life goals. Yet, research highlighting the strengths and weaknesses of different methodological approaches has not been published. This study compared the results of a suite of qualitative methods (questionnaire, focus group, semi-structured interview, "case in point" ethnographic observation, photographic images, and carer proxy response) by identifying the advantages and disadvantages of each method employed. It also foregrounds an effective mix of methods that is likely to produce an adequate representation of the views of people with disabilities within the context of open-ended exploratory questions.

  16. Experimental Investigation of Damage and Fracture Mechanisms Controlling the Performance of Full Aperture Easy Open Ends for Food Containers

    2011-05-01

    Can manufacturers produce hundreds of millions of cans annually, increasingly, food cans are being opened by lifting a tab on the can end that initiates a fracture, which then propagates around a circumferential score. The damage and fracture mechanisms that lead to crack initiation and propagation in the opening process, however, are not fully understood, therefore optimisation of easy open end scores is largely based on trial and error. This paper presents an experimental analysis that concentrates on the combined shear and bending forces as applied to the particular industrial method concerning full aperture easy open ends. The influence of a gradually increasing gap measured between the score and shear force location on traditional groove geometries and depths are examined for two different packaging steels. Earlier studies have shown that the complete opening cycle depends on fracture modes I, II & III as well as their combination. Experimental results for Modes I, II & III will be presented, however attention will focus on the behaviour of the initial fracture point, whereby prior investigations have shown it to be influenced primarily by mode II shearing. After initial specimen manufacture, where the score is formed by pressing a punch into a thin steel sheet the predeformed scored specimens are loaded in shear to simulate the local stress field found during the initial opening phase. Experiments have been completed using a novel Mode II experimental technique that has been designed for use in the majority of commercially available tensile test machines. Experimental results indicate that opening forces can change radically with different gap sizes and that there is considerable potential for the industrialised process of can end manufacture to be optimised through the efficient management and control of the can ends dimensional parameters.

    267 undergraduate students in an interdisciplinary environmental sustainability course were divided into 66 groups for the duration of the semester. The formation of the groups proceeded by first assigning all of the science majors to groups in a random order. This was followed by assigning the engineering majors, the liberal arts majors, and finally the business majors in turn. After all of the students had been assigned to a group, every group had at least one engineering student and one science student. 11 groups had a liberal arts student but no business student. 26 groups had a business student but no liberal arts student. 29 groups were composed of students from all four majors. During the semester, the groups created an environmental action plan to address one of Singapore's major sustainability concerns: food. In service of the course's emphasis on interdisciplinary communication, the groups were required to create a video to support their environmental action plan. The evaluation method for the videos built on our prior work with rubrics (Hartman & Goodkin, 2016). While we provided a number of examples of videos communicating environmental action plans, students were not prescribed a particular format for their video. To the consternation of some students, the instructor deliberately left the video assessment open-ended. After the semester ended, a researcher coded all 66 videos for the food sustainability issues they identified, their proposed solutions, and their video approach. Approaches included animations, virtual handwriting/drawing, role-playing, PowerPoint presentations, and picture slideshows. Given the open-ended nature of the video project, we hypothesized that groups would converge on approaches that at least one team member was familiar with. We knew from prior work with the business school, that its students engage in role-play activities fairly frequently. Teams with a business major and without a liberal arts major adopted the role

    This study aimed at estimating the consumer's willingness to pay (WTP) more for value-added pomegranate juice using the contingent valuation method (CVM). The WTP was estimated applying the open-ended elicitation technique with 454 consumers in two supermarkets located in Rio de Janeiro, Brazil. The average consumer's WTP more for pomegranate juice was estimated in R$2.04 (Brazilian currency) and the income elasticity coefficient at the midpoint was 0.19, i.e., a 10% increase in consumer income will increase, on average, 1.9% the WTP of pomegranate juice (ceteris paribus). Therefore, the income elasticity coefficient was considered inelastic, once an increase in income would have low effect on the WTP for these consumers. The results indicated that the consumers were interested in acquiring a non-traditional juice processed using a technology that preserves vitamins and antioxidants, maintains the flavor of "fresh juice" without colorants and preservatives, despite the pomegranate is not part of the Brazilian diet.

    2018-01-01

    Open End Winding Induction Motors (OEWIM) are popular for electric vehicles, ship propulsion applications due to less DC link voltage. Electric vehicles, ship propulsions require ripple free torque. In this article, an enhanced three-level voltage switching state scheme for direct torque controlled OEWIM drive is implemented to reduce torque and flux ripples. The limitations of conventional Direct Torque Control (DTC) are: possible problems during low speeds and starting, it operates with variable switching frequency due to hysteresis controllers and produces higher torque and flux ripple. The proposed DTC scheme can abate the problems of conventional DTC with an enhanced voltage switching state scheme. The three-level inversion was obtained by operating inverters with equal DC-link voltages and it produces 18 voltage space vectors. These 18 vectors are divided into low and high frequencies of operation based on rotor speed. The hardware results prove the validity of proposed DTC scheme during steady-state and transients. From simulation and experimental results, proposed DTC scheme gives less torque and flux ripples on comparison to two-level DTC. The proposed DTC is implemented using dSPACE DS-1104 control board interface with MATLAB/SIMULINK-RTI model.

    Full Text Available This paper presents a new dual circularly polarized feed that provides good axial ratio over wide angles and low cross-polarized radiation in backward direction. A circular waveguide open end is fed with two orthogonally polarized waves in phase quadrature by a pair of printed crossed dipoles and a compact connectorized quadrature hybrid coupler. The waveguide aperture is loaded with a dielectric cylinder to reduce the cross-polarization beyond 90 degrees off the boresight. The fabricated feed has, at 5.5 GHz, 6.33-dBic copolarized gain, 3-dB beamwidth of 106°, 10-dB beamwidth of 195°, 3-dB axial ratio beamwidth of 215°, maximum cross-polarized gain of −21.4 dBic, and 27-dB port isolation. The reflection coefficient of the feed is less than −10 dB at 4.99–6.09 GHz.

    High-intensity focused ultrasound (HIFU) has become an attractive therapeutic tool for noninvasive tumor treatment. The key component of HIFU systems is the acoustic transducer, which generates a focal region of high-intensity focused ultrasonic energy. A key determinant of safety in HIFU treatment is the size of the focal region. To achieve subwavelength focusing, we previously investigated the feasibility of an ultrasonic spherical cavity resonator (USCR) with two open ends. To further investigate the properties of the USCR, experiments and simulations were performed to comprehensively characterize the acoustic field generated. The emphasis was on the field formation process, the pressure distribution, the frequency dependence, and the acoustic nonlinearity. As a novel simulation approach, an axisymmetric isothermal multi-relaxation-time lattice Boltzmann method (MRT-LBM) model was used to numerically analyze the acoustic field. The reliability of this model was verified by comparing the results generated with those from experiments. The MRT-LBM model gave new insight into conventional acoustic numerical simulations and provided significant indications for USCR parameter optimization. The USCR demonstrated its feasibility for application in HIFU treatment or in other fields that demand high-precision focusing.

    Compliance with safety guidelines prescribed in terms of maximum electromagnetic power absorption (specific absorption rate or SAR) for any 1- or 10-g of tissue is required for all newly introduced personal wireless devices such as wireless PCs. The prescribed SAR measuring system is a planar phantom with a relatively thin base of thickness 2.0 mm filled with a lossy fluid to simulate dielectric properties of the tissues. A well-characterized, broadband irradiator is required for SAR system validation or submerged E-field probe calibration for the Wi-Fi frequencies in the 5-6 GHz band. We describe an open-ended waveguide system that may be used for this purpose. Using a fourth-order polynomial least-squares fit to the experimental data gives SAR variations close to the bottom surface of the phantom that are in excellent agreement with those obtained using the finite-difference time-domain (FDTD) numerical method. The experimentally determined peak 1- and 10-g SARs are within 1 to 2% of those obtained using the FDTD both at 5.25 and 5.8 GHz

    Canine tick-borne apicomplexan parasites have emerged in recent years, showing a wider geographic distribution and increased global prevalence. A reverse line blot assay was performed on 219 blood samples collected from domestic dogs for simultaneous detection of all named canine piroplasm species as well as Hepatozoon canis. Ten samples hybridized to the Theileria/Babesia and Babesia catch all probes but did not hybridize to any species-specific probe tested, suggesting the presence of an unrecognized Babesia species or genotype. Sequencing results showed 91.5%, 91.9%, 92.4%, 92.4%, and 89.2% similarity to B. canis, B. vogeli, B. rossi, B. gibsoni, and B. conradae, respectively. The highest homology (98.1-98.5%) observed was with unnamed Babesia sp. isolates (Ludhiana and Malbazar) described in dogs, Babesia sp. of buffalo origin, Babesia sp. Kashi 2, and Babesia orientalis, along with Babesia occultans of cattle origin. The partial cox1 sequence indicated that this isolate was most similar to Babesia sp. 1 HG-2012, with an identity of 86.5%. The survey revealed high prevalence of haemoprotozoans in domestic dogs (57.5%, CI 50.7-64.2), with Hepatozoon canis the most prevalent (54.3%, CI 47.5-61.117%), followed by Babesia sp. (4.6%, CI 2.2-8.2), B. vogeli (1.4%; CI 0.3-3.9), and B. canis (0.4%, CI 0-2.5). Combined infection of Hepatozoon canis and Babesia sp. was detected in five (2.3%, CI 0.7-5.2) samples and of H. canis and B. vogeli in two (0.9%, CI 0.1-3.2) dogs. The study contributes insight into the distribution and phylogenetic diversity of canine piroplasms in Turkey. Copyright © 2017 Elsevier Ltd. All rights reserved.

    often closed-ended. The outcomes are known in advance and students replicate procedures recommended by the teacher. Over the years, I have come to appreciate the great opportunities created by allowing students investigative freedom in physics laboratories. I have realized that a laboratory environment in which students are free to conduct investigations using procedures of their own design can provide them with varied and rich opportunities for discovery. This paper describes what open-ended laboratory investigations have added to my high school physics classes. I will provide several examples of open-ended laboratories and discuss the benefits they conferred on students and teacher alike.

    Squeeze film dampers (SFD) provide load isolation and attenuate rotor vibrations in high speed turbomachinery. Operating parameters such as whirl frequency, amplitude of journal motion, and value of external pressure supply determine the SFD dynamic force response and its dissipation of mechanical energy. Measurements of pressure fields and fluid film forces in a fully submerged open-end squeeze film damper are presented for tests with rotor speeds to 5,000 cpm and low supply pressures. The damper has a clearance of 381 {micro}m (0.015 in.) and the journal describes circular centered orbits of amplitudes ranging from 30 to 50% of the bearing clearance. Experimental film pressures depict a vapor cavitation (close to zero absolute pressure) zone increasing in extent as the whirl frequency increases. Estimated fluid film forces from the measured pressure profiles are found to be proportional to whirl speed and lubricant viscosity. Test cross-coupled damping coefficients (C{sub rt}) are smaller than predicted values based on the short-length bearing model with a {pi} film cavitation assumption. The direct damping coefficients (C{sub tt}) are larger than theoretical values, especially at low frequencies where the dynamic cavitation region has not grown to half the circumferential flow extent. The experiments demonstrate the viscous character of the fluid film forces in a SFD test apparats where fluid inertia effects are minimal (squeeze film Reynolds number less than one). On the other hand, the extent of the cavitation zone appears to be dominant on the generation of fluid film forces.

  13. Comparisons of an open-ended vs. forced-choice 'mind reading' task: implications for measuring perspective-taking and emotion recognition.

    Directory of Open Access Journals (Sweden)

    Tracy G Cassels

    Full Text Available Perspective-taking and emotion recognition are essential for successful social development and have been the focus of developmental research for many years. Although the two abilities often overlap, they are distinct and our understanding of these abilities critically rests upon the efficacy of existing measures. Lessons from the literature differentiating recall versus recognition memory tasks led us to hypothesize that an open-ended emotion recognition measure would be less reliant on compensatory strategies and hence a more specific measure of emotion recognition abilities than a forced-choice task. To this end, we compared an open-ended version of the Reading the Mind in the Eyes Task with the original forced-choice version in two studies: 118 typically-developing 4- to 8-year-olds (Study 1 and 139 5- to 12-year-olds; 85 typically-developing and 54 with learning disorders (Study 2. We found that the open-ended version of the task was a better predictor of empathy and more reliably discriminated typically-developing children from those with learning disorders. As a whole, the results suggest that the open-ended version is a more sensitive measure of emotion recognition specifically.

  14. Open-Ended Waveguide Measurement and Numerical Simulation of the Reflectivity of Petri Dish Supported Skin Cell Monolayers in the mm-wave Range

    Beneduci, Amerigo; Chidichimo, Giuseppe

    2012-05-01

    Open-ended waveguide reflectometry is a promising tool for permittivity and other material properties calculation at mm-waves (30-300 GHz). Measurement of the reflection coefficient does not require sample manipulation, allowing in vivo and in vitro non destructive studies on cells. Here we used this technique for measuring the power reflection coefficient (reflectivity) of water and Petri dish supported human skin melanoma and keratinocyte cell cultures, in the 53-72 GHz frequency range. The dependence of the reflectivity on polystyrene or glass thickness of the Petri base plate and on the cell layer thickness was analyzed. Permittivity data were then easily retrieved by using a plane wave-dominant mode approach for formulating the reflectivity at the aperture of the flange-mounted open-ended rectangular waveguide probe. Limits and validity of such an approximate approach were analyzed and compared with full-wave near field formulations for which magnitude and phase of the reflection coefficient must be measured and solved using complicated systems of integral equations and extensive numerical calculation. Finally, Petri dish reflectivity measured by the open-ended waveguide method was compared with that numerically simulated under far-field exposure conditions used in a large number of in vitro studies. Such an analysis showed that, under certain conditions, open-ended reflectivity values approach the far field ones.

    Full Text Available Mathematics is globally valued for use by an individual and society. It plays a significant role in the development of modern science and technology. Despite its importance students motivation to learn and achievement at national examinations globally and at the KCSE mathematics examination in Kenya particularly has been dismal over the years. The learners low achievement in the subject has been attributed to the didactic teaching methods that the teachers use among other factors. The study of geometry in Mathematics poses a number of difficulties to learners which are different in nature from those of arithmetic and algebra. This is because geometry is primarily abstract in nature. The purpose of this study was to determine the effects of Open Ended Teaching and Learning Approach OETLA on Secondary School students mathematics achievement in learning Three Dimensional Geometry 3DG. The study employed Solomon four non-equivalent control group design. The two experimental groups E1amp E2 received OETLA treatment while the control groups C1ampC2 were taught using the conventional teaching and learning methods. Only E1amp C1 took a pre-test and a post test for all the groups. The target population for this study was form four 17 year old students of secondary schools in Marani Sub County in Kisii County. Purposive sampling was used to obtain the four county mixed-sex secondary schools for the study. A total of 152 students formed the sample size. Students Mathematics Achievement Test SMAT was used to collect data. The instruments were validated by three experts from the department of curriculum and instruction of Egerton University and three Secondary School Mathematics Heads of Department. The reliability of the instruments were established using Cronbachs Alpha. A reliability coefficient of 0.92 was obtained and thus considered acceptable. The SMAT was administered to two groups as a pretest before the treatment and as a posttest to all the four

    Montgomery, Ellen Williamson

    The Martinello Open-ended Science Task (MOST), a performance assessment of children's scientific thinking, was subjected to tests of reliability and validity and to factor analysis. Results indicated that the MOST is capable of yielding scores that are (1) stable over time, (2) related to criterion scores, and (3) sensitive to instruction designed to improve students' scientific thinking skills. The past fifteen years have seen the development of a variety of assessment techniques designed as alternatives to norm-referenced, standardized science achievement tests. The MOST was developed as a diagnostic tool to measure children's observational and inferential thinking skills with minimal time and resource requirements. Students' responses to questions about an unfamiliar natural object presented to them are coded for the number of occurrences of descriptors, metaphors, incorrect inferences, correct inferences, information-seeking questions, and hypothesis-testing questions, yielding six scale scores and a grand total. Data for the study came from the evaluation of the Minority Mathematics and Science Education Cooperative (MMSEC), a federally funded teacher training project designed to improve science and mathematics instruction. Elementary students (n = 230) from four elementary schools, one participating in MMSEC and one control school in each of two urban Texas cities, completed the MOST in Year One of the study. A subset of these subjects (n = 172) was recovered for a second administration of the MOST in the spring of Year Two. Standardized science achievement test scores were available for a subsample of these students. Significant test/retest reliability was identified for the MOST Grand Total and three of its scales. Significant criterion-related validity evidence was provided by Year One data only. Evidence of predictive validity was found for the combined subjects and the control group taken alone. Construct validity (instructional sensitivity) evidence was

    The LAMOST spectral survey provides a rich databases for studying stellar spectroscopic properties and chromospheric activity. We cross-matched a total of 105,287 periodic variable stars from several photometric surveys and databases (CSS, LINEAR, Kepler, a recently updated eclipsing star catalogue, ASAS, NSVS, some part of SuperWASP survey, variable stars from the Tsinghua University-NAOC Transient Survey, and other objects from some new references) with four million stellar spectra published in the LAMOST data release 2 (DR2). We found 15,955 spectra for 11,469 stars (including 5398 eclipsing binaries). We calculated their equivalent widths (EWs) of their Hα, Hβ, Hγ, Hδ and Caii H lines. Using the Hα line EW, we found 447 spectra with emission above continuum for a total of 316 stars (178 eclipsing binaries). We identified 86 active stars (including 44 eclipsing binaries) with repeated LAMOST spectra. A total of 68 stars (including 34 eclipsing binaries) show chromospheric activity variability. We also found LAMOST spectra of 12 cataclysmic variables, five of which show chromospheric activity variability. We also made photometric follow-up studies of three short period targets (DY CVn, HAT-192-0001481, and LAMOST J164933.24+141255.0) using the Xinglong 60-cm telescope and the SARA 90-cm and 1-m telescopes, and obtained new BVRI CCD light curves. We analyzed these light curves and obtained orbital and starspot parameters. We detected the first flare event with a huge brightness increase of more than about 1.5 magnitudes in R filter in LAMOST J164933.24+141255.0.

  19. Computer-Assisted, Self-Interviewing (CASI Compared to Face-to-Face Interviewing (FTFI with Open-Ended, Non-Sensitive Questions

    John Fairweather PhD

    2012-07-01

    Full Text Available This article reports results from research on cultural models, and assesses the effects of computers on data quality by comparing open-ended questions asked in two formats—face-to-face interviewing (FTFI and computer-assisted, self-interviewing (CASI. We expected that for our non-sensitive topic, FTFI would generate fuller and richer accounts because the interviewer could facilitate the interview process. Although the interviewer indeed facilitated these interviews, which resulted in more words in less time, the number of underlying themes found within the texts for each interview mode was the same, thus resulting in the same models of national culture and innovation being built for each mode. Our results, although based on an imperfect research design, suggest that CASI can be beneficial when using open-ended questions because CASI is easy to administer, capable of reaching more efficiently a large sample, and able to avoid the need to transcribe the recorded responses.

    To evaluate the true necessity of open end ureteral catheter insertion in patients with moderate to severe pelvicalyceal system dilation treated with percutaneous nephrolithotomy (PNL) under sonographic guidance. 50 cases treated with PNL under sonographic guidance in prone position for solitary obstructing renal stones were evaluated. Patients were randomly divided into two groups; Group 1: Patients in whom a open end ureteral catheter was inserted prior to the procedure; Group 2: Patients receiving no catheter before PNL. In addition to the duration of the procedure as a whole and also all relevant stages as well, radiation exposure time, hospitalization period, mean nephrostomy tube duration, mean drop in Hb levels and all intra and postoperative complications have been evaluated. Mean size of the stones was 308.5 ± 133.2 mm2. Mean total duration of the PNL procedure in cases with open end ureteral catheter was significantly longer than the other cases (p < 0.001). Evaluation of the outcomes of the PNL procedures revealed no statistically significant difference between two groups regarding the stone-free rates (86% vs 84%). Additionally, there was no significant difference with respect to the duration of nephrostomy tube, hospitalization period and secondary procedures needed, complication rates as well as the post-operative Hb drop levels in both groups (p = 0.6830). Our results indicate that the placement of an open end ureteral catheter prior to a PNL procedure performed under sonographic access may not be indicated in selected cases presenting with solitary obstructing renal pelvic and/or calyceal stones.

    Dye-sensitized solar cells (DSSCs) were fabricated using open-ended freestanding TiO₂ nanotube arrays functionalized with Ag nanoparticles (NPs) in the channel to create a plasmonic effect, and then coated with large TiO₂ NPs to create a scattering effect in order to improve energy conversion efficiency. Compared to closed-ended freestanding TiO₂ nanotube array-based DSSCs without Ag or large TiO₂ NPs, the energy conversion efficiency of closed-ended DSSCs improved by 9.21% (actual efficiency, from 5.86% to 6.40%) with Ag NPs, 6.48% (actual efficiency, from 5.86% to 6.24%) with TiO₂ NPs, and 14.50% (actual efficiency, from 5.86% to 6.71%) with both Ag NPs and TiO₂ NPs. By introducing Ag NPs and/or large TiO₂ NPs to open-ended freestanding TiO₂ nanotube array-based DSSCs, the energy conversion efficiency was improved by 9.15% (actual efficiency, from 6.12% to 6.68%) with Ag NPs and 8.17% (actual efficiency, from 6.12% to 6.62%) with TiO₂ NPs, and by 15.20% (actual efficiency, from 6.12% to 7.05%) with both Ag NPs and TiO₂ NPs. Moreover, compared to closed-ended freestanding TiO₂ nanotube arrays, the energy conversion efficiency of open-ended freestanding TiO₂ nanotube arrays increased from 6.71% to 7.05%. We demonstrate that each component-Ag NPs, TiO₂ NPs, and open-ended freestanding TiO₂ nanotube arrays-enhanced the energy conversion efficiency, and the use of a combination of all components in DSSCs resulted in the highest energy conversion efficiency.

    Patient information leaflets (PILs) are required with all licensed medicines throughout the European Union (EU) and they must include information about all side effects and their likelihood. This has led to criticism of a lack of balance, with little information included about potential benefits. Recent European Medicines Agency guidance proposed the inclusion of benefit information, and this study examined the current prevalence and type of such information in PILs in the EU. A survey and content analysis of the English translation of PILs in the EUwas carried out. Random quota sampling was used on the most frequently dispensed (n = 50) and newly licensed medicines (n = 50) in 2011/2. Leaflets were searched for benefit information meeting predefined criteria, and data synthesised and categorised into 10 categories. Eighty-five (85%) leaflets described how the medicine works, with 45 providing information about the rationale for treatment (more commonly for newly licensed (32/50) than most commonly dispensed medicines (13/50; P information. Current PILs do not appropriately communicate information about benefit. At the basic level, around a half did not include information about treatment rationale or whether the treatment was to treat symptoms, curative or preventative. However, for true informed decision making, patients need quantitative information about benefits and none of the leaflets provided this. © 2016 Royal Pharmaceutical Society.

    Full Text Available Many native chili varieties are becoming extinct due to the lack of economic incentives for farmers to their continued cultivation in Peru. A potential high value pro-poor market for selling native chilies is the international tourism segment. The objectives of this research were to assess the acceptability of the potential introduction of dried native chilies in the international tourism segment by identifying the motivations for buying dried chilies as souvenirs, and then by evaluating the factors influencing the price premiums’ magnitudes related to different label information conditions, such as information about the farmer community, traditional cooking recipes, organic certification, and Fairtrade certification. A face-to-face survey was conducted with 200 international tourists at the airport in Cuzco, Peru. The data were analyzed using a probit and tobit models with sample selection. The results suggest that dried native chilies would have a relatively good acceptance among international tourists. About 62% of the respondents indicated they would buy dried native chilies, and of them, 62%–74% would pay an average price premium ranging from S/1.16–1.58 for different label information conditions. Nevertheless specific marketing campaigns should be designed for different types of international tourists in order to maximize the economic benefits for small-holder farmers.

    Serum thyroid hormone concentration is regulated through the hypothalamic-pituitary-thyroid axis. This study aimed to clarify the relationships between thyroid hormone regulation and ultrasonographic findings in subjects with thyroid nodules detected during thyroid ultrasound examination for the Fukushima Health Management Survey. As of October 31, 2014, a total of 296,253 subjects, who had been living in Fukushima Prefecture at the time of the Fukushima nuclear power plant accident and were aged ≤18 years on March 11, 2011, participated in two concurrent screening programs. In the primary screening, thyroid nodules were detected in 2241 subjects. A secondary confirmatory thyroid ultrasound examination and blood sampling for thyroid function tests were performed on 2004 subjects. The subjects were reassessed and classified into disease-free subjects (Group 1), subjects with cysts only (Group 2), subjects with nodules (Group 3), and subjects with malignancy or suspected malignancy (Group 4). Serum concentrations of free triiodothyronine (fT3), free thyroxine (fT4), thyrotropin (TSH), thyroglobulin, and the fT3/fT4 ratio were classified according to the diagnoses. Inverse relationships between age and log TSH values (Spearman's correlation r = -0.311, p = 0.015), serum fT3 concentration (r = -0.688, p < 0.001), and the fT3/fT4 ratio (r = -0.520, p < 0.001) were observed in Group 1. When analysis of covariance with Bonferroni post hoc comparisons was used in the four groups, the log TSH values were significantly lower in both Group 3 and Group 4 compared with Group 1 and Group 2 after correcting for age (p < 0.001; Group 1 vs. Group 3, p = 0.016; Group 1 vs. Group 4, p = 0.022; Group 2 vs. Group 3, p = 0.001; Group 2 vs. Group 4, p = 0.008). However, no significant differences were observed between the four groups regarding levels of fT3, fT4, fT3/fT4 ratio, and thyroglobulin (p = 0.304, 0.340, 0.208, and 0

    Use of open-ended Problem-Based Learning (PBL) in biology classrooms has been limited by the difficulty in designing problem scenarios such that the content learned in a course can be predicted and controlled, the lack of familiarity of this method of instruction by faculty, and the difficulty in assessment. Here we present the results of a study in which we developed a team-based interdisciplinary course that combined the fields of biology and civil engineering across three years. We used PBL scenarios as the only learning tool, wrote the problem scenarios, and developed the means to assess these courses and the results of that assessment. Our data indicates that PBL changed students' perception of their learning in content knowledge and promoted a change in students' learning styles. Although no statistically significant improvement in problem-solving skills and critical thinking skills was observed, students reported substantial changes in their problem-based learning strategies and critical thinking skills.

    Full Text Available Mutual funds are one of the key suppliers of liquidity in Romanian capital market. This paper uses quarterly data on Romanian open-end funds starting with 2006 until 2010. We find that significant negative flows (outflows were registered beginning with the end of 2007 (equity funds, during 2008 (equity funds, balanced funds, other funds and bond funds in the last 2 quarters of the year and from 2009 to 2010 (in the case of money market funds. There is evidence that the changing market conditions attract differently the incoming flows in these mutual funds. This is the reason why such perturbations affect investors’ confidence for these investment vehicles and impose the reorientation of the investment funds and of their investors to other alternatives in order to preserve their capital.

    Problems were surveyed and evaluated with respect to solar tracking mechanisms and rotary joints for coolant piping. An analytical development of celestial mechanics, one- and two-axis tracking configurations and the effect of tracking accuracy versus collector efficiency are reported. Daily operational requirements and tracking modes were defined and evaluated. A literature and patent search on solar tracking technology was performed. Tracking system and control system performance specifications were determined. Alternative conceptual tracking approaches were defined and a cost and performance evaluation of a mechanical tracking concept was performed. Fluid coupling service specifications were determined. The cost and performance of several types of actuators and error detectors were evaluated with respect to solar tracking mechanisms.

    1981-04-01

    The United States Department of Energy (DOE), formerly the US ERDA, has initiated a nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR). This program is part of the US National Uranium Resource Evaluation, designed to provide an improved estimate for the availability and economics of nuclear fuel resources and make available to industry information for use in exploration and development of uranium resources. The Los Alamos National Laboratory is responsible for completing the HSSR in Rocky Mountain states of New Mexico, Colorado, Wyoming, and Montana and in the state of Alaska. This report contains a compilation of 100 prime references on uranium hydrogeochemical and stream sediment reconnaissance as internationally practiced prior to 1977. The major emphasis in selection of these references was directed toward constructing a HSSR program with the purpose of identifying uranium in the Los Alamos National Laboratory area of responsibility. The context of the annotated abstracts are the authors' concept of what the respective article contains relative to uranium geochemistry and hydrogeochemical and stream sediment surveying. Consequently, in many cases, significant portions of the original articles are not discussed. The text consists of two parts. Part I contains 100 prime references, alphabetically arranged. Part II contains 60 select annotated abstracts, listed in chronological order

    To assess how authors would describe their contribution to the submitted manuscript without reference to or requirement to satisfy authorship criteria of the International Committee of Medical Journal Editors (ICMJE), we analyzed responses of authors to an open-ended question "Why do you think you should be the author on this manuscript?". Responses of authors (n=1425) who submitted their manuscripts (n=345) to the Croatian Medical Journal, an international general medical journal, from March 2009 until July 2010 were transcribed and matched to ICMJE criteria. Statements that could not be matched were separately categorized. Responses according to the number of authors or their byline position on the manuscript were analyzed using Mann-Whitney U test and Moses test of extreme reactions. The number of authors per manuscript ranged from 1 to 26 (median=4, IQR=3-6), with the median of 2 contributions per author (IQR=2-3). Authors' responses could be matched to the ICMJE criteria in 1116 (87.0%) cases. Among these, only 15.6% clearly declared contributions from all 3 ICMJE criteria; however, if signing of the authorship form was taken as the fulfillment of the third ICMJE criterion, overall fraction of deserving authorship was 54.2%. Non-ICMJE contributions were declared by 98 (7.6%) authors whose other contributions could be matched to ICMJE criteria, and by 116 (13.0%) authors whose contributions could not be matched to ICMJE criteria. The most frequently reported non-ICMJE contribution was literature review. Authors on manuscripts with more than 8 authors declared more contributions than those on manuscript with 8 or fewer authors: median 2, IQR 1-4, vs. median 2, IQR 1-3, respectively (Mann Whitney U test, p=0.001; Moses Test of Extreme Reactions, pauthors (n=9; 31.0%) reported contributions that could not be matched to any ICMJE criterion.

    2017-06-01

    In November 2010 the United Nations General Assembly set up a working group to strengthen the protection of human rights for older persons (UN Open-ended Working Group on Ageing) with the United Nations Resolution A/C.3/65/L.8/Rev.1. In December 2016 the members of the working group met for the seventh time and discussed how they can approach the fulfillment of the mandate. In addition to better implementation, the strengthening of rights can consist of closing existing gaps or further differentiation of the rights in order to give the member states better guidance on how to implement them. To improve the human rights of older persons a task of the members of the working group would be to examine the existing rights and, where possible, adjust them to the real needs of the group. One of the major challenges facing the working group is already apparent: who belongs to the group of older persons and how could the group be described? This article deals with the presentation of the international process, new developments at the regional level and the attitudes of the member states and the civil society. A further aim is to present the possibilities and effects of a comprehensive legally binding instrument.

  18. The Use of Open-Ended Problem-Based Learning Scenarios in an Interdisciplinary Biotechnology Class: Evaluation of a Problem-Based Learning Course Across Three Years†

    2012-01-01

    Use of open-ended Problem-Based Learning (PBL) in biology classrooms has been limited by the difficulty in designing problem scenarios such that the content learned in a course can be predicted and controlled, the lack of familiarity of this method of instruction by faculty, and the difficulty in assessment. Here we present the results of a study in which we developed a team-based interdisciplinary course that combined the fields of biology and civil engineering across three years. We used PBL scenarios as the only learning tool, wrote the problem scenarios, and developed the means to assess these courses and the results of that assessment. Our data indicates that PBL changed students’ perception of their learning in content knowledge and promoted a change in students’ learning styles. Although no statistically significant improvement in problem-solving skills and critical thinking skills was observed, students reported substantial changes in their problem-based learning strategies and critical thinking skills.

    Questionnaire development, validation and completion. Develop comprehensive survey of sexuality issues including validated self-report versions of the International Spinal Cord Injury male sexual function and female sexual and reproductive function basic data sets (SR-iSCI-sexual function). People with spinal cord damage (SCD) living in the community, Australia from August 2013 to June 2014. An iterative process involving rehabilitation medicine clinicians, a nurse specialising in sexuality issues in SCD and people with SCD who developed a comprehensive survey that included the SR-iSCI-sexual function. Participants recruitment through spinal rehabilitation review clinic and community organisations that support people with SCD. Surveys completed by 154 people. Most were male (n=101, 65.6%). Respondents' median age was 50 years (interquartile range (IQR) 38-58), and they were a median of 10 years (IQR 4-20) after the onset of SCD. Sexual problems unrelated to SCD were reported by 12 (8%) respondents, and 114 (n=75.5%) reported sexual problems because of SCD. Orgasms were much less likely (χ(2)=13.1, P=0.006) to be normal in males (n=5, 5%) compared with females (n=11, 22%). Males had significantly worse (χ(2)=26.0, P=0.001) psychogenic genital functioning (normal n=9, 9%) than females (normal n=13, 26%) and worse (χ(2)=10.8, P=0.013) reflex genital functioning. Normal ejaculation was reported in only three (3%) men. Most (n=26, 52%) women reported reduced or absent menstruation pattern since SCD. The SR-iSCI-sexual function provides a useful tool for researchers and clinicians to collect information regarding patient-reported sexual functioning after SCD and to facilitate comparative studies.

  2. Developing a weighting strategy to include mobile phone numbers into an ongoing population health survey using an overlapping dual-frame design with limited benchmark information.

    In 2012 mobile phone numbers were included into the ongoing New South Wales Population Health Survey (NSWPHS) using an overlapping dual-frame design. Previously in the NSWPHS the sample was selected using random digit dialing (RDD) of landline phone numbers. The survey was undertaken using computer assisted telephone interviewing (CATI). The weighting strategy needed to be significantly expanded to manage the differing probabilities of selection by frame, including that of children of mobile-only phone users, and to adjust for the increased chance of selection of dual-phone users. This paper describes the development of the final weighting strategy to properly combine the data from two overlapping sample frames accounting for the fact that population benchmarks for the different sampling frames were not available at the state or regional level. Estimates of the number of phone numbers for the landline and mobile phone frames used to calculate the differing probabilities of selection by frame, for New South Wales (NSW) and by stratum, were obtained by apportioning Australian estimates as none were available for NSW. The weighting strategy was then developed by calculating person selection probabilities, selection weights, applying a constant composite factor to the dual-phone users sample weights, and benchmarking to the latest NSW population by age group, sex and stratum. Data from the NSWPHS for the first quarter of 2012 was used to test the weighting strategy. This consisted of data on 3395 respondents with 2171 (64%) from the landline frame and 1224 (36%) from the mobile frame. However, in order to calculate the weights, data needed to be available for all core weighting variables and so 3378 respondents, 2933 adults and 445 children, had sufficient data to be included. Average person weights were 3.3 times higher for the mobile-only respondents, 1.3 times higher for the landline-only respondents and 1.7 times higher for dual-phone users in the mobile frame

    The methodology commonly used to estimate disease burden, featuring ratings of severity of individual conditions, has been criticized for ignoring co-morbidity. A methodology that addresses this problem is proposed and illustrated here with data from the World Health Organization World Mental Health Surveys. Although the analysis is based on self-reports about one's own conditions in a community survey, the logic applies equally well to analysis of hypothetical vignettes describing co-morbid condition profiles. Face-to-face interviews in 13 countries (six developing, nine developed; n=31 067; response rate=69.6%) assessed 10 classes of chronic physical and nine of mental conditions. A visual analog scale (VAS) was used to assess overall perceived health. Multiple regression analysis with interactions for co-morbidity was used to estimate associations of conditions with VAS. Simulation was used to estimate condition-specific effects. The best-fitting model included condition main effects and interactions of types by numbers of conditions. Neurological conditions, insomnia and major depression were rated most severe. Adjustment for co-morbidity reduced condition-specific estimates with substantial between-condition variation (0.24-0.70 ratios of condition-specific estimates with and without adjustment for co-morbidity). The societal-level burden rankings were quite different from the individual-level rankings, with the highest societal-level rankings associated with conditions having high prevalence rather than high individual-level severity. Plausible estimates of disorder-specific effects on VAS can be obtained using methods that adjust for co-morbidity. These adjustments substantially influence condition-specific ratings.

    In a 2-part study, we first examined the results of 71 surveyed physicians who provided responses on how they address the management of patients who maintained either a pacemaker or a defibrillator during radiation treatment. Second, a case review study is presented involving 112 medical records reviewed at 18 institutions to determine whether there was a change in the radiation prescription for the treatment of the target cancer, the method of radiation delivery, or the method of radiation image acquisition. Statistics are provided to illustrate the level of administrative policy; the level of communication between radiation oncologists and heart specialists; American Joint Committee on Cancer (AJCC) staging and classification; National Comprehensive Cancer Network (NCCN) guidelines; tumor site; patient׳s sex; patient׳s age; device type; manufacturer; live monitoring; and the reported decisions for planning, delivery, and imaging. This survey revealed that 37% of patient treatments were considered for some sort of change in this regard, whereas 59% of patients were treated without regard to these alternatives when available. Only 3% of all patients were identified with an observable change in the functionality of the device or patient status in comparison with 96% of patients with normal behavior and operating devices. Documented changes in the patient׳s medical record included 1 device exhibiting failure at 0.3-Gy dose, 1 device exhibiting increased sensor rate during dose delivery, 1 patient having an irregular heartbeat leading to device reprogramming, and 1 patient complained of twinging in the chest wall that resulted in a respiratory arrest. Although policies and procedures should directly involve the qualified medical physicist for technical supervision, their sufficient involvement was typically not requested by most respondents. No treatment options were denied to any patient based on AJCC staging, classification, or NCCN practice standards. Copyright

    J Rasmus Nielsen

    Full Text Available Trawl survey data with high spatial and seasonal coverage were analysed using a variant of the Log Gaussian Cox Process (LGCP statistical model to estimate unbiased relative fish densities. The model estimates correlations between observations according to time, space, and fish size and includes zero observations and over-dispersion. The model utilises the fact the correlation between numbers of fish caught increases when the distance in space and time between the fish decreases, and the correlation between size groups in a haul increases when the difference in size decreases. Here the model is extended in two ways. Instead of assuming a natural scale size correlation, the model is further developed to allow for a transformed length scale. Furthermore, in the present application, the spatial- and size-dependent correlation between species was included. For cod (Gadus morhua and whiting (Merlangius merlangus, a common structured size correlation was fitted, and a separable structure between the time and space-size correlation was found for each species, whereas more complex structures were required to describe the correlation between species (and space-size. The within-species time correlation is strong, whereas the correlations between the species are weaker over time but strong within the year.

  7. A malacological survey in the Manso Power Plant, State of Mato Grosso, Brazil: new records of freshwater snails, including transmitters of schistosomiasis and exotic species

    Full Text Available Introduction Schistosomiasis is a parasitic disease of public health concern in Brazil, and the construction of hydroelectric dams, in addition to increasing permanent human settlement and tourism, has created conditions suitable for the establishment of mollusks that can transmit schistosomiasis. Such areas require a number of actions to prevent the establishment of schistosomiasis. This paper reports on a freshwater malacological survey carried out in the geographical area of the Manso Power Plant. Methods Mollusks were collected in 18 municipalities in the State of Mato Grosso between February 2002 and February 2004 (qualitative study and from April 2009 to February 2011 (quantitative study. Results Thirty-one species of mollusks were collected, including newly recorded species (Antillorbis nordestensis and Burnupia ingae. In addition, the geographic distributions of known species, including Biomphalaria straminea, a snail vector of Schistosoma mansoni, were expanded. A total of 4,507 specimens were collected in the APM Manso reservoir (Usina Hidrelétrica de Aproveitamento Múltiplo de Manso during the quantitative study, and Biomphalaria amazonica was found in six of the 10 localities analyzed. The Afroasiatic species Melanoides tuberculata, introduced after February 2009, was the dominant species (relative abundance 94.96%. Conclusions The study area is epidemiologically important due to the occurrence of B. straminea and B. amazonica, which are vectors of schistosomiasis, and M. tuberculata, a snail host of Centrocestus formosanus, which is responsible for centrocestiasis transmission. Observations of M. tuberculata and the exotic freshwater clams Corbicula fluminea and Corbicula largillierti raise concerns about biodiversity.

    While many librarians have been asked to participate in systematic reviews with researchers, often these researchers are not familiar with the systematic review process or the appropriate role for librarians. The purpose of this study was to identify the challenges and barriers that librarians face when collaborating on systematic reviews. To take a wider view of the whole process of collaborating on systematic reviews, the authors deliberately focused on interpersonal and methodological issues other than searching itself. To characterize the biggest challenges that librarians face while collaborating on systematic review projects, we used a web-based survey. The thirteen-item survey included seventeen challenges grouped into two categories: methodological and interpersonal. Participants were required to indicate the frequency and difficulty of the challenges listed. Open-ended questions allowed survey participants to describe challenges not listed in the survey and to describe strategies used to overcome challenges. Of the 17 challenges listed in the survey, 8 were reported as common by over 40% of respondents. These included methodological issues around having too broad or narrow research questions, lacking eligibility criteria, having unclear research questions, and not following established methods. The remaining challenges were interpersonal, including issues around student-led projects and the size of the research team. Of the top 8 most frequent challenges, 5 were also ranked as most difficult to handle. Open-ended responses underscored many of the challenges included in the survey and revealed several additional challenges. These results suggest that the most frequent and challenging issues relate to development of the research question and general communication with team members. Clear protocols for collaboration on systematic reviews, as well as a culture of mentorship, can help librarians prevent and address these challenges.

    Anxiety and depression are common in the perinatal period. Telephone interventions, including telephone peer support and counselling, have been developed to support those experiencing perinatal mental illness. PANDA Post and Antenatal Depression Association provides support to women and men experiencing perinatal mental illness via the Australian National Perinatal Depression Helpline, encompassing both volunteer peer support and professional counselling. This study aimed to explore the experiences of callers to the Helpline. A cross-sectional survey design was used. All new callers from 1(st) May to 30(th) September 2013 were invited to participate. The survey, adapted from a previous survey of PANDA callers, included 23 questions using Likert-type scales, demographic and open-ended questions. Thematic network analysis was undertaken for responses to open-ended questions. 124 responses were received (124/405; 30% response). The majority of callers had called the Helpline regarding themselves (90%), with over one third (33%) of all callers seeking crisis support and help. Ninety-nine per cent of respondents 'agreed' or 'strongly agreed' that staff and/or volunteers understood their concerns, and 97% 'agreed' or 'strongly agreed' that overall PANDA had helped them. Callers described the PANDA service as uniquely tailored to the perinatal period, providing accessible, non-judgemental understanding and support, with a global theme from open-ended comments describing PANDA as 'a safe space to be heard and receive support without judgement'. Recommendations for service changes included increased hours of availability. Callers reported positive experiences of accessing support from the PANDA National Perinatal Depression Helpline. The Helpline was described as an accessible and acceptable telephone support for individuals experiencing perinatal mental illness. Recommendations for changes to the service included an increase in hours of operation to enable greater

    An aerial radiological survey was conducted of major sections of the Tonopah Test Range (TTR) in central Nevada from August through October 1993. The survey consisted of aerial measurements of both natural and man-made gamma radiation emanating from the terrestrial surface. The initial purpose of the survey was to locate depleted uranium (detecting 238 U) from projectiles which had impacted on the TTR. The examination of areas near Cactus Springs Ranch (located near the western boundary of the TTR) and an animal burial area near the Double Track site were secondary objectives. When more widespread than expected 241 Am contamination was found around the Clean Slates sites, the survey was expanded to cover the area surrounding the Clean Slates and also the Double Track site. Results are reported as radiation isopleths superimposed on aerial photographs of the area

    A daily mineral supplement is useful for those who are at risk of a deficiency. Some Western reports suggest that mineral supplement users have healthy behaviors and are not mineral-deficient. It is unknown whether the same phenomenon is observed in Japan where there is a different dietary culture. The aim of this study was to examine the characteristics of personal behaviors including food consumption nationwide among mineral supplement users from the National Health and Nutrition Survey in Japan 2003-2010. Data were obtained from 16,275 adults aged 20-59 years who completed sociodemographic, health status, and 1-day household dietary assessments. Supplement users were compared with non-users. Logistic regression models were utilized to identify the characteristics of food consumption and calcium and iron supplement use, using the medium intake group as a reference. Overall, 2.1% and 1.4% of adults reported using calcium supplements and iron supplements, respectively. Calcium supplement users were more likely to be physically active, non-smokers, and eat less fat compared with non-users. Furthermore, they were more likely than non-users to consume a higher intake of calcium from foods such as tea, vegetables, seaweeds, and fruits. Iron supplement users were more likely than non-users to be non-smokers. These individuals tended to have a high intake of seaweeds and fruits. Japanese adults who had healthier behaviors were more likely to use mineral supplements, especially calcium. Mineral supplement users tended to choose healthy foods such as seaweeds and fruits, without considering their overall mineral consumption.

    The accuracy of dietary assessments has emerged as a major concern in nutritional epidemiology and new dietary assessment tools using computer technology to increase accuracy have been developed in many countries. The purpose of this study was to develop a web-based computer-assisted personal interview system (CAPIS) for conducting dietary assessment and to evaluate its practical utilization among Koreans. The client software was developed using Microsoft's ClickOnce technology, which allows communication with a database system via an http server to add or retrieve data. The system consists of a tracking system for the subject and researcher, a data-input system during the interview, a calculation system for estimating food and nutrient intake, a data-output system for presenting the results, and an evaluation system for assessing the adequacy of nutrient and food intake. Databases of the nutrient composition of common food (n = 3,642), recipes for common dishes (n = 1,886), and photos of serving sizes for food and dishes (n = 4,152) were constructed, and logical processes for data collection, calculation, and output were developed. The functionality, on-site applicability, and efficiency of CAPIS were evaluated in a convenience sample of 181 participants (61 males, 120 females; aged 24 to 85) by comparing with manual 24 hour recall method with paper questionnaire. The CAPIS was functioned adequately in the field survey in terms of completeness of function, security, and compliance of researcher and subjects. Regarding on-site applicability, 23.2%, 32.6%, 35.4%, and 43.7% of subjects reported that CAPIS was easier to recall their diet, to estimate the amount consumed, to communicate with the interviewer, and to concentrate on the interview than the manual method with paper questionnaire, respectively. Although CAPIS required more interview time (9 min 42 sec) compared to the manual method (7 min 30 sec), it saved time and cost for data coding and entry (15 min 35

    Occupation is key in socioeconomic research. As in other survey modes, most web surveys use an open-ended question for occupation, though the absence of interviewers elicits unidentifiable or aggregated responses. Unlike other modes, web surveys can use a search tree with an occupation database.

    A general overview of the wildlife associated with riparian habitats at Syncrude's proposed Aurora Mine, located 70 km northeast of Fort McMurray, Alberta on the east side of the Athabasca River, was presented. The area is underlain by bitumen and is being considered for bitumen extraction and production of synthetic crude oil. Two surveys were conducted with the help of experienced trappers from the community at Fort McKay. One was an aerial survey on November 3, 1995, the other a ground survey on November 29-30, 1995. The two surveys yielded 248 observed tracks on four 500 metre transects. The study area was comprised of boreal forest with natural drainage via Stanley Creek into the Muskeg River and via Fort Creek into the Athabasca River. Beavers, fox, weasel, mink, rabbit, wolf, moose, deer, ptarmigan, sharp-tailed grouse and ruffed grouse, lynx, coyote, river otter and mice were associated with riparian habitat on the study area. There was no sign of muskrat in the study area. It was concluded that in order to develop an understanding of reclamation alternatives for mined areas in the region, future detailed examination of the site should be approached through the integration of traditional ecological knowledge and conventional scientific methodology. 26 refs., 12 tabs., 2 figs

    We have completed a 350 MHz Drift-scan Survey using the Robert C. Byrd Green Bank Telescope with the goal of finding new radio pulsars, especially millisecond pulsars that can be timed to high precision. This survey covered {approx}10,300 deg{sup 2} and all of the data have now been fully processed. We have discovered a total of 31 new pulsars, 7 of which are recycled pulsars. A companion paper by Boyles et al. describes the survey strategy, sky coverage, and instrumental setup, and presents timing solutions for the first 13 pulsars. Here we describe the data analysis pipeline, survey sensitivity, and follow-up observations of new pulsars, and present timing solutions for 10 other pulsars. We highlight several sources-two interesting nulling pulsars, an isolated millisecond pulsar with a measurement of proper motion, and a partially recycled pulsar, PSR J0348+0432, which has a white dwarf companion in a relativistic orbit. PSR J0348+0432 will enable unprecedented tests of theories of gravity.

    This study surveyed 188 music therapy educators regarding their views and use of feminist pedagogy and feminist music therapy. The purpose of this study was two-fold: (a) to determine how many music therapy educators used feminist pedagogy and (b) to determine if there was a relationship between the use of feminist pedagogy and academic rank of the participants. Seventy-two participants responded to this study, with 69 participants included for data analysis. Stake and Hoffman's (2000) feminist pedagogy survey was adapted for this study, examining four subscales of feminist pedagogy: (a) participatory learning, (b) validation of personal experience/development of confidence, (c) political/ social activism, and (d) critical thinking/open-mindedness. The results revealed that 46% (n=32) of participants identified as feminist music therapists and 67% (n=46) of participants identified as using feminist pedagogy. Results of a mixed analysis of variance revealed a statistically significant difference within the four survey subscales (p<.0001), no significant difference (p=.32) for academic rank, and no significant interaction (p=.08) of academic rank and the four survey subscales. Tukey's post hoc analysis of the data indicated that the survey subscale measuring political activism (p<.0001) was significantly lower than the other three survey subscales. In addition, a qualitative analysis on open-ended responses is also included. Discussion of the results, limitations, and areas for future research are addressed.

    2014-01-01

    Midwifery in the United States suffers from a lack of diversity. More than 91% of midwives are white, and more than 98% are women. Little research has explored the experiences of midwives who are men or transgender. Invitation to an Internet survey was sent to the membership of the American College of Nurse-Midwives. Thirty-one participants who identified as men or transgender completed the survey, which included quantitative and open-ended questions about the impact of gender on education and practice. Data analysis of qualitative responses used qualitative description methodology to identify common themes. Four themes described participating men's experiences of education and practice of midwifery. Challenges included feeling singled out as different and being excluded. Supportive factors came from the social support of family, friends, colleagues, and patients, as well as from taking pride in one's work as a midwife. Midwives who identify as transgender described the challenges of others' confusion about their gender, having to hide their true gender identity, and struggling with the resulting loneliness. This survey highlights the challenges faced by midwives who are men or transgender in education and practice. Midwifery values of respect and acceptance for all women and families need to be applied internally to all members of the profession. This will support increased diversity and openness in midwifery. © 2014 by the American College of Nurse‐Midwives.

    This study investigated the association between allergic diseases and comorbid ophthalmologic diseases. We enrolled 14 776 participants who were at least 19 years of age. Multiple logistic regression analyses were used to evaluate the odds ratios for cataracts and glaucoma according to the presence of allergic diseases. Atopic dermatitis was not associated with the development of cataracts and glaucoma. However, asthma and allergic rhinitis were significantly associated with cataracts (hazard ratio [HR] = 1.511, 95% confidence interval [CI] = 1.120-2.039 and HR = 1.565, 95% CI = 1.192-2.054, respectively). This study examined a nationwide, population-based survey, and concluded that cataracts were significantly associated with asthma and allergic rhinitis but not with atopic dermatitis. Efforts should be made to reduce the risk of ophthalmologic complications when treating patients with allergic diseases. © 2018 Japanese Dermatological Association.

    The extent to which health sciences librarians are engaged in research is a little-studied question. This study assesses the research activities and attitudes of Medical Library Association (MLA) members, including the influence of work affiliation. An online survey was designed using a combination of multiple-choice and open-ended questions and distributed to MLA members. Responses were analyzed using descriptive statistics, content analysis, and significance testing. The authors used statistical tools and categorized open-ended question topics by the constant comparative method, also applying the broad subject categories used in a prior study. Pearson's chi-square analysis was performed on responses to determine significant differences among respondents employed in three different institutional environments. Analysis showed that 79% of respondents read research articles at least once a month; 58% applied published research studies to practice; 44% had conducted research; 62% reported acting on research had enhanced their libraries; 38% had presented findings; and 34% had authored research articles. Hospital librarians were significantly less likely than academic librarians to have participated in research activities. Highly ranked research benefits, barriers, and competencies of health sciences librarians are described. Findings indicate that health sciences librarians are actively engaged in research activities. Practice implications for practitioners, publishers, and stakeholders are discussed. Results suggest that practitioners can use published research results and results from their own research to affect practice decisions and improve services. Future studies are needed to confirm and extend these findings, including the need for intervention studies to increase research and writing productivity.

    In 2008 a new clinical anatomy curriculum with integrated medical imaging component was introduced into the University of Sydney Medical Program. Medical imaging used for teaching the new curriculum included normal radiography, MRI, CT scans, and ultrasound imaging. These techniques were incorporated into teaching over the first two years of the program as a part of anatomy practical sessions, in addition to dedicated lectures and tutorials given by imaging specialists. Surveys were conducted between 2009 and 2012 to evaluate the student acceptance of the integration. Students were asked to rate individual activities as well as provide open-ended comments. The number of students who responded to the surveys varied from 40% to 98%. Over 90% of the respondents were satisfied with the overall quality of teaching in the anatomy units. In summary, 48% to 63% of the responding students thought that the specialist imaging lectures helped them learn effectively; 72% to 77% of students thought that the cross-sectional practical sessions helped them to better understand the imaging modalities of CT, MRI, and ultrasound; 76% to 80% of students considered hands-on ultrasound session to be useful in understanding the application of ultrasound in abdominal imaging. The results also revealed key similarities and differences in student perceptions of the new integrated curriculum for students with both a high and low prior exposure to anatomy. Further evaluation will aid in refining the integrated medical imaging program and providing its future direction. © 2014 American Association of Anatomists.

    To promote the succession of history of and the creative use of industrial science technologies, the paper made lists and databases of the articles of industrial technology museums and material halls in Japan. Record/preservation and collection/systematization of history of the industrial technology is useful for forming bases necessary for promotion of future research/development and international contribution. Museums and material halls are the fields for making comprehensive and practical activities. The data were made as one of the basic databases as the first step for promoting activities for examining the technical succession situation in a long term range continuously and systematically. In the classification of the data, the energy relation was divided into electric power, nuclear power, oil, coal, gas and energy in general. Others were classified into metal/mine, electricity/electronics/communication, chemistry/food, ship building/heavy machinery, printing/precision instrument, and textile/spinning. Moreover, the traffic relation was classified into railroad, automobiles/two-wheeled vehicles, airline/space, and ships. Items were also set of life relation, civil engineering/architecture, and general. The total number of the museums for the survey reached 208.

    Field survey was made on the current state of and issues on energy in Vietnam. In Vietnam, firewood is in wide use as non-commercial energy, and sums to a half of total energy consumption. Other energies such as hydroelectric power, petroleum, natural gas and coal are self-sustainable. Commercial energy consumption in 1995 is estimated at 10,070,000t in oil equivalent, which is broken down into 23% for coal, 42% in oil, 5% for natural gas and 30% for electricity. Abundant water resources will form the mainstay of future electric power supply. Commercial production of oil started in 1986 becoming an oil exporting country. Several promising natural gas fields were discovered as the result of the exploration by foreign capital. Coal deposits are estimated to be nearly 3.5 billion tons, and most of them are anthracite. Electric power demand is growing at a higher rate than the economic growth of Vietnam. The growth rate of electric power demand is set to be 1.3 times that of GDP. Since construction funds for new plants cannot be satisfied with the national budget and domestic investment alone, the country is expecting foreign capitals. 21 figs., 36 tabs.

    The intended meaning behind responses to standard questions posed in large-scale health surveys are not always well understood. Systematic follow-up studies, particularly those which pose a few repeated questions followed by open-ended discussions, are well positioned to gauge stability and consistency of data and to shed light on the intended meaning behind survey responses. Such follow-up studies require extensive coordination and face challenges in protecting respondent confidentiality during the process of recontacting and reinterviewing participants. We describe practical field strategies for undertaking a mixed methods follow-up study during a large-scale health survey. The study was designed as a mixed methods follow-up study embedded within the 2014 Ghana Demographic and Health Survey (GDHS). The study was implemented in 13 clusters. Android tablets were used to import reference data from the parent survey and to administer the questionnaire, which asked a mixture of closed- and open-ended questions on reproductive intentions, decision-making, and family planning. Despite a number of obstacles related to recontacting respondents and concern about respondent fatigue, over 92 percent of the selected sub-sample were successfully recontacted and reinterviewed; all consented to audio recording. A confidential linkage between GDHS data, follow-up tablet data, and audio transcripts was successfully created for the purpose of analysis. We summarize the challenges in follow-up study design, including ethical considerations, sample size, auditing, filtering, successful use of tablets, and share lessons learned for future such follow-up surveys.

  18. Research on Control Strategies of an Open-End Winding Permanent Magnet Synchronous Driving Motor (OW-PMSM-Equipped Dual Inverter with a Switchable Winding Mode for Electric Vehicles

    Directory of Open Access Journals (Sweden)

    Liang Chu

    2017-05-01

    Full Text Available An open-end winding permanent magnet synchronous motor (PMSM has a larger range of speed regulation than normal PMSM with the same DC voltage, and the control method is more flexible. It can also manage energy distribution between two power sources without a DC/DC converter. This paper aims at an electric vehicle equipped with OW-PMSM drive system with dual power sources and dual inverters; based on analyzing the external characteristics of each winding mode, we propose a winding mode switching strategy whose torque saturation judgmental algorithm, which is insensitive to motor’s parameters, could automatically realize upswitching of the winding mode. The proposed multi-level current hysteresis modulation algorithm could set the major power source and switch it at any time in independent mode, which accomplishes energy distribution between two power sources; its two control methods, low switching frequency method and high power difference method, could achieve different energy distribution effects. Simulation results confirm the validity and effectiveness of the winding mode switching strategy and current modulation method. They also show that an electric vehicle under the proposed control methods has better efficiency than one equipped with a traditional OW-PMSM drive system under traditional control.

    Sonographer practitioner development involves the expansion and extension of the sonographer role to include reporting on ultrasound examinations. Australian sonographers have not seen the same degree of role extension and expansion as their counterparts in the United Kingdom, despite increasing levels of discussion regarding sonographer practitioner development. The aim of this study was to determine if Australian sonographers want to extend their professional role and what they consider are the important issues associated with role extension. This paper reports on qualitative data derived from a survey of Australian sonographers and investigates if Australian sonographers are interested in extending and expanding their professional role and responsibilities and, if they do, what might be necessary or desirable from a professional point of view for this change to occur. A survey was mailed to all members of the Australian Sonographers Association (ASA) in October 2006. The 31-item survey included 28 closed-ended and 3 opened-ended items to provide both quantitative and qualitative data. The quantitative data will be reported separately. Qualitative data was derived from responses to the opened-ended questions, which asked respondents to elaborate on their attitudes and feelings about role extension and development. Analysis used Nvivo7 software to aid in uncovering common themes from the qualitative data. The analysis focused on the reported incentives or motivations for becoming a sonographer practitioner as well as disincentives or perceived hurdles that would discourage respondents from becoming sonographer practitioners. The three most reported incentives or motivations for becoming a sonographer practitioner were professional recognition, remuneration and increased knowledge. The three most commonly reported disincentives or perceived hurdles that would discourage respondents from becoming sonographer practitioners were legal issues, insurance and further

    A positive patient safety culture (PSC) is one of the most critical components to improve healthcare quality and safety. The Hospital Survey on Patient Safety Culture (HSOPS), developed by the US Agency for Healthcare Research and Quality, has been used to assess PSC in 31 countries. However, little is known about the impact of nurse working hours on PSC. We hypothesized that long nurse working hours would deteriorate PSC, and that the deterioration patterns would vary between countries. Moreover, the common trends observed in Japan, the US and Chinese Taiwan may be useful to improve PSC in other countries. The purpose of this study was to clarify the impact of long nurse working hours on PSC in Japan, the US, and Chinese Taiwan using HSOPS. The HSOPS questionnaire measures 12 sub-dimensions of PSC, with higher scores indicating a more positive PSC. Odds ratios (ORs) were calculated using a generalized linear mixed model to evaluate the impact of working hours on PSC outcome measures (patient safety grade and number of events reported). Tukey's test and Cohen's d values were used to verify the relationships between nurse working hours and the 12 sub-dimensions of PSC. Nurses working ≥60 h/week in Japan and the US had a significantly lower OR for patient safety grade than those working Japan and Chinese Taiwan. Patient safety grade deteriorated and the number of events reported increased with long working hours. Among the 12 sub-dimensions of PSC, long working hours had an impact on 'staffing' and 'teamwork within units' in Japan, the US and Chinese Taiwan.

Positive effects reported with ecigarettes included their usefulness to quit smoking, and the benefits of abstinence from smoking (less coughing, improved breathing, better physical fitness. Respondents also enjoyed the flavour of ecigarettes and the sensation of inhalation. Side effects included dryness of the mouth and throat. Respondents complained about the frequent technical failures of ecigarettes and had some concerns about the possible toxicity of the devices and about their future legal status. Conclusions Ecigarettes were used mainly to quit smoking, and may be helpful for this purpose, but several respondents were concerned about potential toxicity. There are very few published studies on ecigarettes and research is urgently required, particularly on the efficacy and toxicity of these devices.

    Full Text Available Background Respondent fatigue, also known as survey fatigue, is a common problem in the collection of survey data. Factors that are known to influence respondent fatigue include survey length, survey topic, question complexity, and open-ended question type. There is a great deal of interest in understanding the drivers of physician survey responsiveness due to the value of information received from these practitioners. With the recent explosion of mobile smartphone technology, it has been possible to obtain survey data from users of mobile applications (apps on a question-by-question basis. The author obtained basic demographic survey data as well as survey data related to an anesthesiology-specific drug called sugammadex and leveraged nonresponse rates to examine factors that influenced respondent fatigue. Methods Primary data were collected between December 2015 and February 2017. Surveys and in-app analytics were collected from global users of a mobile anesthesia calculator app. Key independent variables were user country, healthcare provider role, rating of importance of the app to personal practice, length of time in practice, and frequency of app use. Key dependent variable was the metric of respondent fatigue. Results Provider role and World Bank country income level were predictive of the rate of respondent fatigue for this in-app survey. Importance of the app to the provider and length of time in practice were moderately associated with fatigue. Frequency of app use was not associated. This study focused on a survey with a topic closely related to the subject area of the app. Respondent fatigue rates will likely change dramatically if the topic does not align closely. Discussion Although apps may serve as powerful platforms for data collection, responses rates to in-app surveys may differ on the basis of important respondent characteristics. Studies should be carefully designed to mitigate fatigue as well as powered with the

    In recent decades, the term student housing has been highlighted as a body of knowledge in housing studies. In providing better quality of life, student housing evolved into a critical agenda in developing higher education learning. This research paper aims to discuss on a pilot study examining student housing preferences among university and college students should they reside off-campus. The research aims at identifying the attributes of off-campus student housing preferences to give a significant input for the development of an off-campus student housing preferences conceptual framework. This research is a cross-sectional study in which survey participants are currently-enrolled students throughout the period of survey. During this pilot study, questionnaires were distributed among university students in Shah Alam, Selangor in Malaysia. A total of 86 survey questionnaires were collected, consisting of questions reflecting students' background, Likert scale questions to specify their preferences, and open-ended questions. This preliminary pilot result shows that the 46 variables student housing preferences have a good reliability and validity. The outcomes from this research provide insight into students' preferences on how off-campus housing should be developed. Since Selangor is divided into various districts with a plethora of different local contexts including different university campuses, there is a need for further study to avoid generalization.

    Deep-water hermit crabs of the family Parapaguridae can be abundant (up to 20 kg or 1000 hermit crab individuals per haul) in the trawl bycatch collected during South African demersal abundance research surveys. Until recently, only two parapagurid species had been recognized in the bycatch; Parapagurus bouvieri Stebbing, 1910, and Sympagurus dimorphus (Studer, 1883). Detailed examination of numerous samples of parapagurid specimens from research surveys revealed the existence of a third, undescribed species previously confounded with S. dimorphus , but in fact belonging to a different genus. This new species, Paragiopagurus atkinsonae sp. n. is the 25 th in the genus Paragiopagurus Lemaitre, 1996, and has been found only in a small region on the West Coast shelf of South Africa, at depths of 199-277 m. The species is herein fully described and illustrated, including colour images, µCT scans of selected body parts, and CO1 barcode data. The new species is morphologically most similar to P. ventilatus Lemaitre, 2004, a species associated with hydrothermal vents, but differs in armature of the fourth antennal segment (armed with a spine on the dorsolateral distal angle vs. unarmed in P. ventilatus ); setation of the antennal flagella (nearly naked vs. with dense setae in P. ventilatus ); plumose setation on the third maxillipeds and basal segments of chelipeds (absent vs. present in P. ventilatus ); number of rows of scales on the propodal rasp of pereopod 4 (two or three rows vs. one row in P. ventilatus ); and degree of telson asymmetry (weakly asymmetrical vs. strongly asymmetrical in P. ventilatus ). Paragiopagurus atkinsonae sp. n. is superficially similar to S. dimorphus , with males of the two species showing the same extreme degree of sexual dimorphism on the right cheliped, general light orange colouration, and frequent use of colonial zoanthid carcinoecia for pleonal protection.

    2016-03-01

    There are concerns about prisoners and detainees not having equal access to end-of-life care while in prison. There is a lack of existing literature about the standards of end-of-life care in UK prisons. The aim of this study was to investigate the views of current and former prison nurses with regard to the end-of-life care being provided in UK prisons. Prison nurses were invited to participate in an online survey and asked about their role in the prison, prisoners' access to healthcare facilities, and any barriers and good practices to end-of-life care. The survey included open-ended and closed questions. The closed questions were analysed using descriptive statistics. The open-ended responses were coded and grouped into themes. 31 (N=31) prison nurses responded to the survey. The reported barriers to end-of-life care included some prison regimes, lack of appropriate care and visiting facilities, lack of privacy and inadequate visiting hours. Respondents also reported examples of good practice, including having access to specialist palliative care and specialist equipment, and being able to receive visits from family and friends. The findings suggest that there is considerable variability in the end-of-life care provided to prisoners in the UK. Further research is needed in order to reduce the health inequalities and improve the quality of end-of-life care experienced by prisoners in the UK. Published by the BMJ Publishing Group Limited.

    The Parkland Airshed Management Zone (PAMZ) was established in Alberta in 1997 as a non-profit society to implement a zonal approach to monitoring and managing air quality. In 1999, the Human Health Committee was established as a subcommittee of PAMZ with the intent of carrying out a public survey of opinions about air quality and health in the David Thompson Health Region (DTHR). A total of 1570 households were contacted in the fall 2000 survey, of which 469 responded. The survey was divided into the following four parts: (1) air quality and health, (2) activities affecting air quality, (3) strategies to address air quality issues, and (4) demographics. A total of 31 questions were asked, including two open-ended questions. Results of the survey indicate that about 40 per cent of the respondents believe that current air quality in Alberta is having an impact on their health. When asked about how much attention should be given to examining the impacts of various activities upon air quality, the strongest support was for looking at the oil and gas sector and at indoor air quality in the workplace. Almost equal preference was expressed for either regulation or further research as a strategy to improve air quality. tabs., figs.

    2010-11-01

    Editors of scientific literature rely heavily on peer reviewers to evaluate the integrity of research conduct and validity of findings in manuscript submissions. The purpose of this study was to describe the ethical concerns of reviewers of nursing journals. This descriptive cross-sectional study was an anonymous online survey. The findings reported here were part of a larger investigation of experiences of reviewers. Fifty-two editors of nursing journals (six outside the USA) agreed to invite their review panels to participate. A 69-item forced-choice and open-ended survey developed by the authors based on the literature was pilot tested with 18 reviewers before being entered into SurveyMonkey(TM). A total of 1675 reviewers responded with useable surveys. Six questions elicited responses about ethical issues, such as conflict of interest, protection of human research participants, plagiarism, duplicate publication, misrepresentation of data and 'other'. The reviewers indicated whether they had experienced such a concern and notified the editor, and how satisfied they were with the outcome. They provided specific examples. Approximately 20% of the reviewers had experienced various ethical dilemmas. Although the majority reported their concerns to the editor, not all did so, and not all were satisfied with the outcomes. The most commonly reported concern perceived was inadequate protection of human participants. The least common was plagiarism, but this was most often reported to the editor and least often led to a satisfactory outcome. Qualitative responses at the end of the survey indicate this lack of satisfaction was most commonly related to feedback provided on resolution by the editor. The findings from this study suggest several areas that editors should note, including follow up with reviewers when they identify ethical concerns about a manuscript.

    The objective of this study was to determine what aspects of prehospital pediatric airway management may contribute to patient safety events. We conducted a 3-phase Delphi survey in prehospital professionals across the United States to identify potential contributors to patient safety events. Respondents ranked how likely factors were to contribute on a 9-point Likert-type scale and were allowed to elaborate through open-ended questions. Analysis was conducted using a mixed-methods approach, including Likert-type responses and open-ended questions which were analyzed for specific themes. All 3 phases of the survey were completed by 492 participants; 50.8% of respondents were paramedics, 22% were emergency medical technician-basics/first responders, and 11.4% were physicians. Seventy-five percent identified lack of experience with advanced airway management, and 44% identified medical decision making regarding airway interventions as highly likely to lead to safety events. Within the domain of technical skills, advanced airway management was ranked in the top 3 contributors to safety events by 71% of participants, and bag-mask ventilation by 18%. Qualitative analysis of questions within the domains of equipment and technical skills identified endotracheal intubation as the top contributor to safety events, with bag-mask ventilation second. In the domains of assessment and decision making, respiratory assessment and knowing when to perform an advanced airway were ranked most highly. This national Delphi survey identified lack of experience with pediatric airway management and challenges in decision making in advanced airway management as high risk for safety events, with endotracheal intubation as the most likely of these.

    The International Classification of Functioning, Disability and Health Children and Youth version (ICF-CY) (WHO) may serve as a tool for the application of holistic models of oral health. The ICF-CY Global Oral Health Survey explored international professional opinion regarding factors relating to child oral health, including social environment, functioning, activity, and participation. Networking resulted in 514 professionals from 81 countries registering for a two-round Delphi survey online. Participants were pooled into 18 groups according to six WHO world regions and three professional groups. In a randomized stratification process, eight from each pool (n = 144) completed the survey. The first round consisted of eight open-ended questions. Open-expression replies were analysed for meaningful concepts and linked using established rules to the ICF-CY. In the second round, items were rated for their relevance to oral health (86% response rate). A total of 86 ICF-CY items and 31 other factors were considered relevant to child oral health and function by at least 80% of professionals. The ICF-CY can describe the holistic experience of oral health in children from the professional perspective. The data from this study will contribute to the development of an ICF-CY Core Set in Oral Health. © 2015 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To identify key attributes of effective disaster/mass casualty first responders and leaders, thereby informing the ongoing development of a capable disaster health workforce. We surveyed emergency response practitioners attending a conference session, the EMS State of the Science: A Gathering of Eagles. We used open-ended questions to ask participants to describe key characteristics of successful disaster/mass casualty first responders and leaders. Of the 140 session attendees, 132 (94%) participated in the survey. All responses were categorized by using a previously developed framework. The most frequently mentioned characteristics were related to incident command/disaster knowledge, teamwork/interpersonal skills, performing one's role, and cognitive abilities. Other identified characteristics were related to communication skills, adaptability/flexibility, problem solving/decision-making, staying calm and cool under stress, personal character, and overall knowledge. The survey findings support our prior focus group conclusion that important characteristics of disaster responders and leaders are not limited to the knowledge and skills typically included in disaster training. Further research should examine the extent to which these characteristics are consistently associated with actual effective performance of disaster response personnel and determine how best to incorporate these attributes into competency models, processes, and tools for the development of an effective disaster response workforce.

    The energy-saving and other global environmental technologies are surveyed by collecting relevant information from various institutes, both abroad and domestic, to contribute to development of ceramic gas turbines. USA has announced a climate change plan, based on the five principles, to promote utilization of high-efficiency technologies and development of new clean technologies. UK is promoting to improve energy efficiency, along with liberalization of its energy markets. Germany concentrates its efforts in the 'Program for Energy Research and Energy Technologies.' France places emphasis on prevention of air pollution and rational use of energy. The R and D trends at public institutes, e.g., universities, for global environmental technologies are surveyed, from which a total of 14 themes are extracted as the seed technologies. At the same time, a total of 9 techniques potentially applicable to the seeds are extracted by mainly reviewing JICST and patent information, and assessed. The R&D trends of the IPCC-related researchers are also surveyed, but provide no theme directly applicable to the seeds. Most of the related themes at the private and public institutes surveyed, both domestic and abroad, are concentrated on carbon dioxide. (NEDO)

    Little is known about the environmental and organisational determinants of workplace violence in correctional health settings. This paper describes the views of health professionals working in these settings on the factors influencing workplace violence risk. All employees of a large correctional health service in New South Wales, Australia, were invited to complete an online survey. The survey included an open-ended question seeking the views of participants about the factors influencing workplace violence in correctional health settings. Responses to this question were analysed using qualitative thematic analysis. Participants identified several factors that they felt reduced the risk of violence in their workplace, including: appropriate workplace health and safety policies and procedures; professionalism among health staff; the presence of prison guards and the quality of security provided; and physical barriers within clinics. Conversely, participants perceived workplace violence risk to be increased by: low health staff-to-patient and correctional officer-to-patient ratios; high workloads; insufficient or underperforming security staff; and poor management of violence, especially horizontal violence. The views of these participants should inform efforts to prevent workplace violence among correctional health professionals.

    In 2015, an interdisciplinary group of psychosocial experts developed The Standards of Psychosocial Care for Children with Cancer and Their Families. This paper presents data from a national survey of pediatric oncology social workers and their experiences in delivering psychosocial care to children and families. In total, 107 social workers from 81 cancer institutions participated in a 25-item online survey that mirrored the 15 Standards for Psychosocial Care. Both closed and open-ended questions were included. Social work participants reported that psychosocial support is being provided at most cancer centers surveyed, primarily by social workers and child life specialists, addressing adaptation to the cancer diagnosis, treatment, and transitions into survivorship or end-of-life care and bereavement. While social workers reported offering comprehensive services throughout the cancer trajectory, many of the 2015 Standards are not being systematically implemented. Areas for improvement include funding for psychosocial support staff and programs, incorporation of standardized assessment measures, assessment for financial burden throughout treatment and beyond, consistent access to psychology and psychiatry, integrated care for parents and siblings, and more inclusion of palliative care services from time of diagnosis.

    First and second molars in the lower jaw are the most commonly missing teeth. As in other jaw regions with tooth loss, implant therapy is an attractive concept. Owing to the wide dimension of the molar teeth, wide implants seem to be a natural choice. However, wide implants in posterior mandibular regions sometimes present a problem. As an oxidized surface seems to facilitate implant integration and to result in a stronger fixation to bone, it was hypothesized that this surface would improve the performance of wide implants in posterior mandibles. As high initial stability most often is achieved in this region, it was hypothesized that the load per se is not a problem. The purpose of the present study is to evaluate immediate loading of Brånemark System TiUnite Wide-Platform implants (Nobel Biocare AB, Gothenburg, Sweden) supporting single molar crowns in the lower jaw. The study includes 44 patients treated in three separate private dental offices between March 2001 and June 2002. A total of 50 implants were placed, and all implants have passed the 6-month follow-up; 24 have been followed up for 1 year. All implants were provided with provisional crowns in centric occlusion at the time of surgery. No implant has been lost. Marginal bone levels were found in accordance with normal biologic width requirements. Resonance frequency analysis showed high and consistent implant stability. No biomechanical problems were found associated with the use of wide implants, and the potential physiologic problem in dense mandibular bone was eliminated. Although limited by being a short-term study, the result encourages immediate loading of single Brånemark System TiUnite Wide-Platform implants placed in the molar regions in the lower jaw.

    The aim of this study was to assess healthcare provider perspectives on barriers to medication adherence and to discover recommendations for interventions among providers of pediatric solid-organ transplant patients. An anonymous online survey was administered to a multidisciplinary pool of pediatric transplant providers from February 2015 to March 2016. It consisted of 15 questions regarding transplant providers' attitudes, clinical practice, and beliefs pertaining to medication adherence among teenage solid-organ transplant recipients. Data were analyzed using descriptive statistics. Responses to open-ended questions were coded and categorized into themes. One hundred ten surveys were completed by providers specializing in pediatric heart, kidney, liver, lung, and/or intestinal transplantation. Commonly cited reasons for poor adherence were forgetting/poor planning (94%), the desire to be normal (86%), lack of support (86%), and poor parental monitoring (79%). Suggestions to improve adherence included increasing peer and family support, providing education, and incorporating technology into adherence regimens. Barriers to adherence in transplant patients are recognized by providers and are both similar to and disparate from patient and family identified barriers published in the literature. Providers recognize the importance of education, social support, and technologically driven interventions on improving outcomes in the transplant population. © 2017 John Wiley & Sons A/S.

    We sought to evaluate how neurologists approach situations in which families request prolonged organ support after declaration of death by neurologic criteria (DNC). We surveyed 938 members of the American Academy of Neurology (AAN) who treat critically ill patients, including 50% who practice in states with accommodation exceptions (states that require religious or moral beliefs to be taken into consideration when declaring death or discontinuing organ support: California, Illinois, New Jersey, New York), and 50% who practice in nonaccommodation states. The survey was completed by 201/938 individuals (21% response rate), 96 of whom were from accommodation states and 105 of whom were from nonaccommodation states. Both groups reported encountering situations in which families requested continuation of organ support after DNC (48% from accommodation states and 46% from nonaccommodation states). In a hypothetical scenario where a request is made to continue organ support after DNC (outside of organ donation), 48% of respondents indicated they would continue support due to fear of litigation. In reply to an open-ended question, respondents requested that the AAN generate guidelines and advocate to codify laws regarding organ support after DNC, and to improve public and physician education on DNC. Our findings suggest that it is relatively common for neurologists who treat critically ill patients to encounter families who object to discontinuation of organ support after DNC at some point during their career. It would be beneficial for physicians, families, and society to rely on clear medicolegal guidelines on management of this situation. © 2016 American Academy of Neurology.

    A method to determine total phosphorus (TP) in the same digests prepared for total Kjeldahl nitrogen (TKN) determinations is desribed. The batch, high-temperature (block digester), HG(II)-catalyzed digestion step is similar to U.S. Geological Survey methods I-2552-85/I-4552-85 and U.S. Environmental Protection Agency method 365.4 except that sample and reagent volumes are halved. Prepared digests are desolvated at 220 degrees Celsius and digested at 370 degrees Celsius in separate block digesters set at these temperatures, rather than in a single, temperature-programmed block digester. This approach is used in the method escribed here, which permits 40 calibrants, reference waters, and smaples to be digested and resolvated in about an hour. Orthophosphate ions originally present in samples, along with those released during the digestion step, are determined colorimetrically at a rate of 90 tests per hour by an automated version of the phosphoantimonylmolybdenum blue procedure. About 100 microliters of digest are required per determination. The upper concentration limit is 2 milligrams per liter (mg/L) with a method detection limt of 0.01 mg/L. Repeatability for a sample containing approximately 1.6 mg/L of TP in a high suspended-solids matrix is 0.7 percent. Between-day precision for the same sample is 5.0 percent. A dialyzer in the air-segmented continuous flow analyzer provides on-line digest cleanup, eliminated particulates that otherwise would interfere in the colorimetric finish. An single-channel analyzer can process the resolvated digests from two pairs of block digesters each hour. Paired t-test analysis of TP concentrations for approximately 1,600 samples determined by the new method (U.S. Geologial Survey methods I-2610-91 and I-4610-91) and the old method (U.S. Geological Survey methods I-2600-85 and I-4600-85) revealed positive bias in the former of 0.02 to 0.04 mg/L for surface-water samples in agreement with previous studies.

    There are many commonplace examples of waves moving along a curved path in an inhomogeneous media. There are reports of a simple lecture demonstration of light bending in a sugar solution being used to motivate students in physics, geophysics, and acoustics courses. For those students who wish to pursue this topic we discuss many avenues of additional research. With relatively simple equipment one can measure the index of refraction n (y,t) and its first and second spatial derivatives as well as the time dependence. The analysis can be approached from a generalization of Snell's law, the equations for the eikonal, Fermat's principle, and the classical approximation and analogies with trajectories of particles

    At present, three modern types of mirror machines for plasma confinement and heating exist in Novosibirsk (Multi-mirror,-GOL-3, Gas Dynamic Trap,-GDT, and Tandem Mirror,- AMBAL-M). From the engineering point of view all these systems are very attractive because of simple axisymmetric geometry of magnetic configurations. In this paper, the status of GOL-3 and GDT machines is presented. The most crucial experiments for the mirror concept are described such as a demonstration of different principles of suppression of longitudinal electron heat conductivity (GDT, GOL-3), finding of MHD stable regimes of confinement of high β (more than 0.4) plasma in axisymmetric geometry of magnetic field, an effective heating of a dense plasma (of order of 10 21 m-3) by high current relativistic electron beam (GOL-3), etc. In the case of multi-mirror geometry (GOL-3) significant increase of confinement time of hot plasma (up to several tens times) was obtained in comparison with single mirror geometry. Besides, electron heating (up to 2 keV) in result of high current electron beam — plasma interaction, the heating of ions (up to 2 keV) was discovered in the multi-mirror geometry (55 mirror cells with total length of the trap equal to 12 meters). There was no any effect of ion heating in the single mirror geometry. The reasons of appearance of the ion heating in multi-mirror geometry are discussed. It should be mentioned that on the basis of the GOL-3 and GDT one can obtain an important information for ITER and for future fusion program. In the case of GOL-3 the longitudinal energy density flux of plasma after heating by REB can be so high as 50 MJ/m2. A lot of experiments can be made on plasma-wall interaction (evaporation, erosion and ionization of wall material, propagation of the impurity ions along magnetic field lines at long distances, etc). Some of these experiments are described in this paper. Using principle of confinement of "warm" collisional plasma placed in gas dynamic trap (GDT) together with oblique injection of fast atoms of D and T one can create a powerful 14 MeV neutron source for constructed materials tests of future fusion reactors with a moderate irradiation area (about 1 square meter) and, accordingly, with low tritium consumption. It should be mentioned that there is no one candidate to the plasma based neutron source with such moderate consumption of tritium (about 150 gram/year) and electric power (60 MW). The experimental results with NB injection of 4 MW are described and the experiments of the next step (GDT-U) with 10 MW injection are discussed.

    Significant progress of the simplest axisymmetric magnetic systems for plasma confinement and heating is described. Two of such systems are presented in this paper: multi mirror (GOL-3) and gas dynamic (GDT) traps. In the GOL-3 case the temperatures T e ∼T∼2 keV were obtained in a dense (of order of 10 21 m -3 ) plasma and the maximum value of nτ E ∼2·10 18 m -3 s was achieved. Any physical limitations which could prevent from further grow of plasma parameters did not find out. The most important results obtained in the experiments on GDT are described. A new step (GDT-U) has been prepared and the first preliminary experiments with quasi-stationary plasma heating have started. According to calculations, the parameters of the GDT-U should demonstrate the feasibility of 'moderate' (0.5 MW/m 2 ) 14 MeV neutron source for structural materials tests of fusion reactor

From the engineering point of view all these systems are very attractive because of simple axi-symmetric geometry of magnetic configurations. In this paper, the status of GOL-3 and GDT machines is presented. The most crucial experiments for the mirror concept are described, i.e. the demonstration of different principles for the suppression of electron heat conductivity (in GDT and GOL-3), finding of MHD-stable regimes for the confinement of high b (> 0.4) plasma in axi-symmetric geometry of the magnetic field, an effective heating of a dense (of the order of 10 21 m -3 ) plasma by high-current relativistic electron beam (in GOL-3), etc. In the case of multi-mirror geometry (GOL-3) a significant increase in confinement time of hot plasma (up to several tens times) was observed in a comparison with single-mirror geometry. Besides electron heating (up to 2 keV) the heating of ions (up to 2 keV) was discovered in the multi-mirror geometry (55 mirror cells of the total length of the trap equal to 12 meters), as a result of the interaction of high-current electron beam with plasma. There was no effect of the ion heating in the single-mirror geometry. The reasons of the appearance of the ion heating in the multi-mirror configuration are discussed. It should especially be mentioned that on the basis of the GDT experiment it is possible to make a very important intermediate step. Using 'warm' plasma and oblique injection of fast atoms of deuterium and tritium one can create a powerful 14-MeV neutron source with a moderate irradiation area for material tests (e.g. about 1 square meter), and with a low tritium consumption. It should also be mentioned that there is no other candidate for the construction of a plasma-based neutron source with such low tritium consumption (about 150 grams/year). (author)

  19. Eight year experience in open ended instrumentation laboratory

    2015-10-01

    When designing laboratory courses in a Physics Major we consider a range of objectives: teaching Physics; developing lab competencies; instrument control and data acquisition; learning about measurement errors and error propagation; an introduction to project management; team work skills and scientific writing. But nowadays we face pressure to decrease laboratory hours due to the cost involved. Many universities are replacing lab classes for simulation activities, hiring PhD. and master students to give first year lab classes, and reducing lab hours. This leads to formatted lab scripts and poor autonomy of the students, and failure to enhance creativity and autonomy. In this paper we present our eight year experience with a laboratory course that is mandatory in the third year of Physics and Physical Engineering degrees. Since the students had previously two standard laboratory courses, we focused on teaching instrumentation and giving students autonomy. The course is divided in two parts: one third is dedicated to learn computer controlled instrumentation and data acquisition (based in LabView); the final 2/3 is dedicated to a group project. In this project, the team (2 or 3 students) must develop a project and present it in a typical conference format at the end of the semester. The project assignments are usually not very detailed (about two or three lines long), giving only general guidelines pointing to a successful project (students often recycle objectives putting forward a very personal project); all of them require assembling some hardware. Due to our background, about one third of the projects are related to Optics.

  20. Control of open end plasma flow utilizing orbital stochasticity

    Hojo, Hitoshi

    1995-01-01

    It has been known that the control of plasma outside the confinement region of diverter plasma and others in a magnetic field confinement device is very important for improveing the confinement of bulk plasma. The control of plasma outside a confinement region bears two roles, one is the reduction of the thermal load on a diverter plate and others due to the plasma particles lost from the confinement region, and another is the restriction of the back flow of cold plasma and impurities generated outside the confinement region to a bulk plasma region. In this study, the new method of controlling plasma outside a confinement region called magnetic diverter is considered. To the plasma particles advancing along magnetic force lines, the reflection and capture of the plasma particles occur in the region of orbital stochasticity, and the thermal load on an end plate and the reverse flow to a bulk plasma region are restricted. The numerical computation model used regarding the particle control utilizing the orbital stochasticity and the results of calculating the orbit of plasma particles in a magnetic field are reported.

    We study a modified version of the naming game, a recently introduced model which describes how shared vocabulary can emerge spontaneously in a population without any central control. In particular, we introduce a mechanism that allows a continuous interchange with the external inventory of words. A playing strategy, influenced by the hierarchical structure that individuals’ reputation defines in the community, is implemented. We analyze how these features influence the convergence times, the cognitive efforts of the agents, and the scaling behavior in memory and time.

    The use of social media and social networking sites has become increasingly common by the current generation of students. Colleges and universities are using social media and social networking sites to advertise, engage and recruit prospective students. The purpose of this study was to evaluate how social media is being used in dental hygiene program admissions and policy. Researchers developed a survey instrument investigating the use of social media. The survey included questions about demographic information, personal use of social media, program use of social media, social media use in admissions and social media policies. An email was sent to 321 dental hygiene program directors asking them to complete the survey. All participants were provided 4 weeks to complete the survey, and 2 reminder emails were sent. A total of 155 responses were received (48.3% response rate). While 84% of respondents indicated their program had a web page, only 20% had an official Facebook page for the program and 2% had a Twitter page. Thirty-five percent had a program policy specifically addressing the use of social media and 31% indicated that their university or institution had a policy. Only 4% of programs evaluate a potential student's Internet presence, mostly by searching on Facebook. Statistically significant differences (p≤0.05) were noted between those respondents with more personal social media accounts and those with fewer accounts, as those with more accounts were more likely to evaluate a potential student's Internet presence. Open ended responses included concern about social media issues, but some uncertainty on how to handle social media in the program. The concern for social media and professionalism was evident and more research and discussion in this area is warranted. Social media is currently being used in a variety of ways in dental hygiene programs, but not in the area of admissions. There is some uncertainty about the role social media should play in a

    Background Prenatal and early life risk factors are associated with childhood obesity. Alaska Native children have one of the highest prevalences of childhood obesity of all US racial/ethnic groups. Methods Using the Pregnancy Risk Assessment Monitoring System (PRAMS) and the follow-up survey at 3 years of age (CUBS), we evaluated health, behavioral, lifestyle and nutritional variables in relation to obesity (95th percentile for body mass index (BMI)) at 3 years of age. Multivariate logistic regression modeling was conducted using Stata 12.0 to evaluate independent risk factors for obesity in non-Native and Alaska Native children. Results We found an obesity prevalence of 24.9% in all Alaskan and 42.2% in Alaska Native 3 year olds. Among Alaska Native children, obesity prevalence was highest in the Northern/Southwest part of the state (51.6%, 95%CI (42.6-60.5)). Independent predictive factors for obesity at age 3 years in Alaska non-Native children were low income (obesity (OR 2.01, 95%CI 1.01-4.01) and longer duration of breastfeeding was protective (OR 0.95, 95%CI 0.91-0.995). Among Alaska Native children, predictive factors were witnessing domestic violence/abuse as a 3 year-old (OR 2.28, 95%CI 1.17-7.60). Among obese Alaska Native children, there was an increased daily consumption of energy dense beverages in the Northern/Southwest region of the state, which may explain higher rates of obesity in this part of the state. Conclusions The high prevalence of obesity in Alaska Native children may be explained by differences in lifestyle patterns and food consumption in certain parts of the state, specifically the Northern/Southwest region, which have higher consumption of energy dense beverages.

    Although pediatrician-reported relevance of Canadian cardiology-specific objectives has been studied, similar data are not available for the 2016 American Board of Pediatrics (ABP) cardiology-specific objectives. This study asked Kentucky trainees, pediatricians, and pediatric cardiologists to identify "most important" content within these objectives. This cross-sectional study used an original, online survey instrument based on the 2016 ABP cardiology-specific objectives. We collected quantitative data (numerical indications of importance) and qualitative data (open-ended replies regarding missing content and difficulty in teaching and learning). Respondents indicated the top two choices of most important items within eight content areas. Descriptive statistics (frequencies and percentages) and chi-square analysis were calculated. Content within categories was organized using naturally occurring "clusters" and "gaps" in scores. Common themes among open-ended qualitative responses were identified using Pandit's version of Glaser and Strauss Grounded theory (constant comparison). Of the 136 respondents, 23 (17%) were residents, 15 (11%) fellows, 85 (62%) pediatricians, and 13 (10%) pediatric cardiologists. Of attendings, 80% reported faculty/gratis faculty status. Naturally occurring clusters in respondent-designated importance resulted in ≤3 "most selected" objectives per content area. Objectives in "most selected" content pertained to initial diagnosis (recognition of abnormality/disease) (n = 16), possible emergent/urgent intervention required (n = 14), building a differential (n = 8), and planning a workup (n = 4). Conversely, themes for "least selected" content included comanagement with subspecialist (n = 15), knowledge useful in patient-family communication (n = 9), knowledge that can be referenced (as needed) (n = 7), and longitudinal/follow-up concerns (n = 5). This study demonstrated the utility of an online survey

    Global warming has significant negative consequences for human health, with some groups at greater risk than others. The extent to which the public is aware of these risks is unclear; the limited extant research has yielded discrepant findings. This paper describes Americans' awareness of the health effects of global warming, levels of support for government funding and action on the issue, and trust in information sources. We also investigate the discrepancy in previous research findings between assessments based on open- versus closed-ended questions. A nationally representative survey of US adults (N = 1275) was conducted online in October 2014. Measures included general attitudes and beliefs about global warming, affective assessment of health effects, vulnerable populations and specific health conditions (open- and closed-ended), perceived risk, trust in sources, and support for government response. Most respondents (61%) reported that, before taking the survey, they had given little or no thought to how global warming might affect people's health. In response to a closed-ended question, many respondents (64%) indicated global warming is harmful to health, yet in response to an open-ended question, few (27%) accurately named one or more specific type of harm. In response to a closed-ended question, 33% indicated some groups are more affected than others, yet on an open-ended question only 25% were able to identify any disproportionately affected populations. Perhaps not surprising given these findings, respondents demonstrated only limited support for a government response: less than 50% of respondents said government should be doing more to protect against health harms from global warming, and about 33% supported increased funding to public health agencies for this purpose. Respondents said their primary care physician is their most trusted source of information on this topic, followed by the Centers for Disease Control and Prevention, the World Health

    Full Text Available The use of a participant survey, administered at the outset of an online course, can provide information useful in the management of the learning environment and in its subsequent redesign. Such information can clarify participants’ prior experience, expectations, and demographics. But the very act of enquiring about the learner also signals the instructor’s social presence, relational interest, and desire to enter into an authentic dialogue. This study examines the use of participant surveys in online management courses. The first section discusses the informational bridges that this instrument provides. The second section considers survey responses to open-ended questions dealing with student sentiments. This analysis suggests that the survey plays a valuable part in accentuating social presence and in initiating relational bridges with participants.

    This report presents precision and accuracy data for volatile organic compounds (VOCs) in the nanogram-per-liter range, including aromatic hydrocarbons, reformulated fuel components, and halogenated hydrocarbons using purge and trap capillary-column gas chromatography/mass spectrometry. One-hundred-four VOCs were initially tested. Of these, 86 are suitable for determination by this method. Selected data are provided for the 18 VOCs that were not included. This method also allows for the reporting of semiquantitative results for tentatively identified VOCs not included in the list of method compounds. Method detection limits, method performance data, preservation study results, and blank results are presented. The authors describe a procedure for reporting low-concentration detections at less than the reporting limit. The nondetection value (NDV) is introduced as a statistically defined reporting limit designed to limit false positives and false negatives to less than 1 percent. Nondetections of method compounds are reported as ?less than NDV.? Positive detections measured at less than NDV are reported as estimated concentrations to alert the data user to decreased confidence in accurate quantitation. Instructions are provided for analysts to report data at less than the reporting limits. This method can support the use of either method reporting limits that censor detections at lower concentrations or the use of NDVs as reporting limits. The data-reporting strategy for providing analytical results at less than the reporting limit is a result of the increased need to identify the presence or absence of environmental contaminants in water samples at increasingly lower concentrations. Long-term method detection limits (LTMDLs) for 86 selected compounds range from 0.013 to 2.452 micrograms per liter (?g/L) and differ from standard method detection limits (MDLs) in that the LTMDLs include the long-term variance of multiple instruments, multiple operators, and multiple

    Background Eliciting cancer survivors’ priorities is essential to address the specific needs of cancer survivor subgroups. Objective To describe long-term rectal cancer survivors’ greatest challenges related to treatment. Design Observational study with cross-sectional survey. Setting Members of Kaiser Permanente, Northern California and Northwest health plans. Patients A survey was mailed to long-term (≥5 years post diagnosis) rectal cancer survivors who had an anastomosis, temporary ostomy, or permanent ostomy. Main Outcome Measures An open-ended question about the greatest challenge related to cancer surgery. We categorized responses using a grounded theory approach with double coding for reliability. Bonferroni-adjusted X2 values were used to assess differences in the proportions of subgroups who mentioned challenges within each response category. Results The survey completion rate was 61% (577/953); 76% (440/577) of participants responded to the greatest challenge question. Respondents’ greatest challenges were bowel/ostomy management (reported by 44%), negative psychosocial effects (37%), late effects of treatment (21%), comorbidities and aging (13%), postoperative recovery (5%), and negative health care experiences (5%). Survivors with temporary ostomy or anastomosis were more likely than survivors with permanent ostomy to report late effects (pchallenges that may not be anticipated during treatment decision-making. Limitations Generalizability is restricted by the lack of ethnically and racially diverse, uninsured (non-Medicare-eligible population), and non-English-speaking participants. Because the survey was cross-sectional and included respondents at different times since diagnosis, we could not adequately address changes in the greatest challenges over time. PMID:27749476

  14. On-the-Job Ethics – Proximity Morality Forming in Medical School: A grounded theory analysis using survey data

    Directory of Open Access Journals (Sweden)

    Hans O. Thulesius, MD, Ph.D.

    2009-03-01

    Full Text Available On-the-job-ethics exist in all businesses and can also be called proximity morality forming. In this paper we propose that medical students take a proximity morality stance towards ethics education at medical school. This means that they want to form physician morality “on the job” instead of being taught ethics like any other subject. On-the-job-ethics for medical students involves learning ethics that is used when practicing ethics. Learning ethics includes comprehensive ethics courses in which quality lectures provide ethics grammar useful for the ethics practicing in attitude exercises and vignette reflections in tutored group discussions. On-the-job-ethics develops professional identity, handles diversity of religious and existential worldviews, trains students described as ethically naive, processes difficult clinical experiences, and desists negative role modeling from physicians in clinical or teaching situations. This grounded theory analysis was made from a questionnaire survey on attitudes to ethics education with 409 Swedish medical students participating. We analyzed over 8000 words of open-ended responses and multiplechoice questions using classic grounded theory procedures, but also compared questionnaire data using statistics such as multiple regression models. The paper gives an example of how grounded theory can be used with a limited amount of survey data.

    Involving patients and the public in research prioritisation is important. Cochrane Airways works with authors to produce systematic reviews of evidence related to chronic airways disease. Cochrane Airways has undertaken activities to identify research priorities, including workshops with stakeholders and consultation with experts. We present the findings of an online survey, designed to align our work with the priorities of people affected by asthma. We promoted a survey comprising open-ended questions via social media to people affected by asthma. We compiled the free-text responses and conducted an exploratory thematic analysis to identify important barriers and facilitators to asthma control. We triangulated findings with other research prioritisation activities to produce new review questions. We received 57 survey responses. Eight main themes emerged, most encompassing both facilitators and barriers: attitudes and knowledge; financial costs; environmental factors and triggers; healthcare systems; lifestyle factors; medication; self-care; and support. Barriers were more frequently mentioned than facilitators and many related to healthcare systems. These findings offer valuable insights into the challenges faced by individuals affected by asthma in the UK, and possibly further afield. We developed a list of priority reviews based on what was said by people in this survey and at a workshop. This demonstrates the real impact that people affected by asthma have on the research agenda of Cochrane Airways. Over the next 2-3 years we will produce reviews that address some of these questions hopefully leading to health benefits.

    The concept of oral health is frequently reduced to the absence of disease, despite existing conceptual models exploring the wider determinants of oral health and quality of life. The International Classification of Functioning, Disability and Health (ICF) (WHO) is designed to qualify functional, social and environmental aspects of health. This survey aimed to reach a consensual description of adult oral health, derived from the ICF using international professional opinion. The Global Oral Health Survey involved a two-round, online survey concerning factors related to oral health including functioning, participation and social environment. Four hundred eighty-six oral health professionals from 74 countries registered online. Professionals were pooled into 18 groups of six WHO world regions and three professional groups. In a randomised stratification process, eight professionals from each pool (n=144) completed the survey. The first round consisted of eight open-ended questions. Open expression replies were analysed for meaningful concepts and linked using established rules to the ICF. In Round 2, items were rated for their relevance to oral health (88% response rate). Eighty-nine ICF items and 30 other factors were considered relevant by at least 80% of participants. International professionals reached consensus on a holistic description of oral health, which could be qualified and quantified using the ICF. These results represent the first step towards developing an ICF Core Set in Oral Health, which would provide a practical tool for reporting outcome measures in clinical practice, for research and epidemiology, and for the improvement of interdisciplinary communication regarding oral health. Professional consensus reached in this survey is the foundation stone for developing an ICF Core Set in Oral Health, allowing the holistic aspects of oral health to be qualified and quantified. This tool is necessary to widen our approach to clinical decision making

    The purpose of this survey was to investigate neonatal nurses' perceptions of knowledge and practice in pain assessment and management. A convenience sample consisted of 237 neonatal nurses with a membership in National Association of Neonatal Nurses (NANN) and neonatal nurses in Connecticut who were not NANN members. A researcher-developed questionnaire, including 36 questions with Likert scale and 2 open-ended questions, was used. The nurses were knowledgeable, and about 50% felt that they received adequate training and continuing education on pain. Participants reported the use of pain assessment tools (81%) and felt confident in uses of pharmacologic (83%) and nonpharmacologic interventions (79%). More than half felt that the pain tool used in their unit was appropriate for neonates (65%) and was an accurate measure (60%). Fewer than half reported that pain was well managed (44%) and that their pain protocols were research evidence based (43%). Nurses' perceptions of well-managed pain were significantly correlated with training, use of appropriate and accurate pain tools, and clear and research-based protocols. Barriers to effective pain management emerged as resistance to change, lack of knowledge, perceived fear of side effects of pain medication and incorrect interpretation of pain signals, lack of time, and lack of trust in the pain assessment tools. Gaps exist in knowledge, evidence, and practice in neonatal assessment and management.

    In the US, once a medical device is made available for use, several requirements have been established by the US Food and Drug Administration (FDA) to ensure ongoing post-market surveillance of device safety and effectiveness. Our objective was to determine how commonly medical device manufacturers initiate post-market clinical studies or augment FDA post-market surveillance requirements for higher-risk devices that are most often approved via the FDA's pre-market approval (PMA) pathway. We conducted a cross-sectional survey of 47 manufacturers with operations in California, Minnesota, and Massachusetts who market devices approved via the PMA pathway. Among 22 respondents (response rate =47%), nearly all self-reported conducting post-market clinical research studies, commonly between 1 and 5; only 1 respondent reported never conducting post-market clinical research studies. While manufacturers most often engaged in these studies to satisfy FDA requirements, other reasons were reported, including performance monitoring and surveillance and market acceptance initiatives. Risks of conducting and not conducting post-market clinical research studies were described through open-ended response to questions. Medical device manufacturers commonly initiate post-market clinical studies at the request of the FDA. Clinical data from these studies should be integrated into national post-market surveillance initiatives.

    Research in an emergency setting such as that with an acute cardiovascular event is challenging because the window of opportunity to treat may be short and may preclude time to obtain informed consent from the patient or their representative. Some perceive that requiring informed consent in emergency situations has limited improvements in care. Vulnerable populations including minorities or residents of low-income countries are at greatest risk of need for resuscitation. Lack of enrollment of such patients would increase uncertainties in treatment benefit or harm in those at greater risk of need for resuscitation. We sought to assess international variation in policies and procedures related to exception from informed consent (EFIC) or deferred consent for emergency research. A brief survey instrument was developed and modified by consensus among the investigators. Included were multiple choice and open-ended responses. The survey included an illustrative example of a hypothetical randomized study. Elicited information included the possibility of conducting such a study in the respondent's country, as well as approvals required to conduct the study. The population of interest was emergency physicians or other practitioners of acute cardiovascular event research. Usable responses were obtained from 44 countries (76% of surveyed). Community opposition to EFIC was noted in 6 (14%) countries. Emergency Medical Services (EMS) providers in 8 (20%) countries were judged unable or unwilling to participate. A majority of countries (36, 82%) required approval by a Research Ethics Committee or similar. Government approval was required in 25 (57%) countries. There is international variation in practices and policies related to consent for emergency research. There is an ongoing need to converge regulations based on the usefulness of multinational emergency research to benefit both affluent and disadvantaged populations. Copyright © 2015.

    The HITECH Act of 2009 enabled the Centers for Medicare & Medicaid Services (CMS) to provide financial incentives to health care providers who demonstrate "meaningful use" (MU) of their electronic health records (EHRs). Despite stakeholder involvement in the rule-making phase, formal input about the MU program from a cross section of providers has not been reported since incentive payments began. To examine the perspectives and experiences of a random sample of health care professionals eligible for financial incentives (eligible professionals or EPs) for demonstrating meaningful use of their EHRs. It was hypothesized that EPs actively participating in the MU program would generally view the purported benefits of MU more positively than EPs not yet participating in the incentive program. Survey data were collected by mail from a random sample of EPs in Washington State and Idaho. Two follow-up mailings were made to non-respondents. The sample included EPs who had registered for incentive payments or attested to MU (MU-Active) and EPs not yet participating in the incentive program (MU-Inactive). The survey assessed perceptions of general realities and influences of MU on health care; views on the influence of MU on clinics; and personal views about MU. EP opinions were assessed with close- and open-ended items. Close-ended responses indicated that MU-Active providers were generally more positive about the program than MU-Inactive providers. However, the majority of respondents in both groups felt that MU would not reduce care disparities or improve the accuracy of patient information. The additional workload on EPs and their staff was viewed as too great a burden on productivity relative to the level of reimbursement for achieving MU goals. The majority of open-ended responses in each group reinforced the general perception that the MU program diverted attention from treating patients by imposing greater reporting requirements. Survey results indicate the need by

  3. Themes Underlying Australian General Practitioner Views towards Chiropractic and Osteopathy: An Assessment of Free Text Data from a Cross-Sectional Survey

    Full Text Available The Australian chiropractic and osteopathic professions underwent a period of significant transformation between 1960 and 2000. This resulted in an improvement in the views held by the medical profession towards the two professions. However, a recent survey of Australian general practitioners (GPs reported that a number of GPs still hold negative views towards chiropractors and osteopaths. This paper examines these views from the perspective of critical realism and explores the generative mechanisms that can influence the willingness of health practitioners to collaborate over patient care. A qualitative analysis of open-ended responses to a survey of 630 Australian GPs was conducted. Unfavourable attitudes of GPs towards chiropractors and osteopaths included perceived lack of safety, efficacy, and inadequacy of training, despite chiropractic’s and osteopathy’s reliance on the same evidence base and similar training to those of other manual therapy professions such as physiotherapy. These attitudes may be underpinned by the professional biases against chiropractic and osteopathy that continue to marginalise the professions within the Australian healthcare system. Continued investment in the research base for chiropractic and osteopathic practice is required, along with raising the awareness of GPs about the education and skills of chiropractors and osteopaths.

    Engineering surveying involves determining the position of natural and man-made features on or beneath the Earth's surface and utilizing these features in the planning, design and construction of works. It is a critical part of any engineering project. Without an accurate understanding of the size, shape and nature of the site the project risks expensive and time-consuming errors or even catastrophic failure.Engineering Surveying 6th edition covers all the basic principles and practice of this complex subject and the authors bring expertise and clarity. Previous editions of this classic text have given readers a clear understanding of fundamentals such as vertical control, distance, angles and position right through to the most modern technologies, and this fully updated edition continues that tradition.This sixth edition includes:* An introduction to geodesy to facilitate greater understanding of satellite systems* A fully updated chapter on GPS, GLONASS and GALILEO for satellite positioning in surveying* Al...

    Community health worker motivation is an important consideration for improving performance and addressing maternal, newborn, and child health in low and middle-income countries. Therefore, identifying health system interventions that address motivating factors in resource-strained settings is essential. This study is part of a larger implementation research project called Nigraan, which is intervening on supportive supervision in the Lady Health Worker Programme to improve community case management of pneumonia and diarrhea in rural Pakistan. This study explored the motivation of Lady Health Supervisors, a cadre of community health workers, with particular attention to their views on supportive supervision. Twenty-nine lady health supervisors enrolled in Nigraan completed open-ended structured surveys with questions exploring factors that affect their motivation. Thematic analysis was conducted using a conceptual framework categorizing motivating factors at individual, community, and health system levels. Supportive supervision, recognition, training, logistics, and salaries are community and health system motivating factors for lady health supervisors. Lady health supervisors are motivated by both their role in providing supportive supervision to lady health workers and by the supervisory support received from their coordinators and managers. Family support, autonomy, and altruism are individual level motivating factors. Health system factors, including supportive supervision, are crucial to improving lady health supervisor motivation. As health worker motivation influences their performance, evaluating the impact of health system interventions on community health worker motivation is important to improving the effectiveness of community health worker programs.

    Customer orientation has gained increasing attention in healthcare. A customer satisfaction survey is one way to raise areas and topics for quality improvement. However, it seems that customer satisfaction surveys have not resulted in quality improvement in healthcare. This article reports how the authors' university hospital laboratory has used customer satisfaction surveys targeted at the health centres in their hospital district. Closed-ended statements of the questionnaire were planned to cover the essential aspects of laboratory services. In addition, an open-ended question asked what was considered to be the most important problem in services. The questionnaires were sent to the medical directors of the health centres. The open-ended question proved to be very useful because the responses specified the main problems in service. Based on the responses, selected dissatisfied customers were contacted to specify their responses and possible corrective actions were taken. It is concluded that a satisfaction survey can be used as a screening tool to identify topics of dissatisfaction. In addition, further clarifications with selected customers are needed to specify the causes for their dissatisfaction and to undertake proper corrective actions. PMID:20205616

    Full Text Available Previous research has shown that offering respondents their preferred mode can increase response rates, but the effect of doing so on how respondents process and answer survey questions (i.e., measurement is unclear. In this paper, we evaluate whether changes in question format have different effects on data quality for those responding in their preferred mode than for those responding in a non-preferred mode for three question types (multiple answer, open-ended, and grid. Respondents were asked about their preferred mode in a 2008 survey and were recontacted in 2009. In the recontact survey, respondents were randomly assigned to one of two modes such that some responded in their preferred mode and others did not. They were also randomly assigned to one of two questionnaire forms in which the format of individual questions was varied. On the multiple answer and open-ended items, those who answered in a non-preferred mode seemed to take advantage of opportunities to satisfice when the question format allowed or encouraged it (e.g., selecting fewer items in the check-all than the forced-choice format and being more likely to skip the open-ended item when it had a larger answer box, while those who answered in a preferred mode did not. There was no difference on a grid formatted item across those who did and did not respond by their preferred mode, but results indicate that a fully labeled grid reduced item missing rates vis-à-vis a grid with only column heading labels. Results provide insight into the effect of tailoring to mode preference on commonly used questionnaire design features.

    A worldwide internet survey was conducted (1) to identify problems of individuals with traumatic brain injury (TBI) addressed by health professionals and (2) to summarize these problems using the International Classification of Functioning, Disability and Health (ICF). A pool of professionals involved in the TBI rehabilitation process that included physicians, nurses, physical therapists, occupational therapists, social workers and psychologists were surveyed to identify problems in functioning and contextual factors of individuals with TBI using open-ended questions. All answers were translated ("linked") to the ICF based on established rules. The frequencies of the linked ICF categories were reported stratified based on context. One-hundred thirty seven professionals from the six World Health Organization regions identified 5656 concepts. 92.66% could be linked to the ICF; 33.03% were related to the domain of body functions, 27.28% to activities and participation, 10.98% to structures and 21.38% to environmental factors. The complexity of TBI was described through the identification of a wide variety of ICF categories. ICF language proved to be a neutral framework allowing the comparison of answers between different professionals in different world regions. People that suffered a traumatic brain injury (TBI) may have a variety of sequelae that impair functioning. The International Classification of Functioning, Disability and Health (ICF) can help in providing information regarding the identification of patients problems and needs as well as planning, implementing and coordinating the rehabilitation process. The ICF provides a frame of reference process illustrated as the rehabilitation cycle that can help during the rehabilitation process in goal setting bringing together the clinicians' and patient's perspectives in a patient oriented biopsychosocial approach. In the field of TBI rehabilitation, activity limitations and participation restrictions are broadly

    Sudden infant death syndrome (SIDS) is a major cause of death among children aged pediatricians' regarding risk factors for SIDS, their familiarity with the first Brazilian SIDS campaign launched in 2009, and self-reported changes in practices following this campaign. Active members of the Brazilian Society for Pediatrics who had been in practice for at least two years at the time of the campaign were invited. Pediatricians answered an online survey including eight multiple-choice questions and one open-ended question. Invitees were chosen by chance draw to reflect the geographic distribution of pediatricians in the five regions of the country. The survey was answered by 1654 pediatricians (mean [SD] age: 46 [11.5] years; mean [SD] professional practice time: 20.2 [11.52] years). Bedding items (77.7%), prone sleeping position (72.9%), bed sharing (66.3%), and smoking (59.2%) were recognized as risk factors for SIDS. Most pediatricians (88.2%) were familiar with the campaign, and 84.7% were aware of the current recommendation of supine sleeping position to prevent SIDS. The effectiveness of the first Brazilian SIDS campaign could be measured by a change in practice; before the campaign, 67.5% recommended lateral position and 23.1% the supine, and after the campaign, 76.2% recommended supine and 10.4% lateral. However, 12.8% still recommend prone position. The majority of pediatricians changed their advice to parents after the educational campaign and became familiar with risk factors for SIDS. Continuous educational campaigns focusing on physicians resistant to changing practices should be provided. Copyright © 2016 Elsevier B.V. All rights reserved.

    Although nurse practitioners (NPs) play a critical role in the delivery of reproductive health services in Canada, there is a paucity of published information regarding the reproductive health education provided in their training programs. Our study aimed to understand better the didactic and curricular coverage of abortion in Canadian NP programs. In 2014, we conducted a 3-contact, bilingual (English-French) mailed survey to assess the coverage of, time dedicated to and barriers to inclusion of 17 different areas of reproductive health, including abortion. We also asked respondents to speculate on whether or not mifepristone would be incorporated into the curriculum if approved by Health Canada for early abortion. We analyzed our results with descriptive statistics and used inductive techniques to analyze the open-ended questions for content and themes. Sixteen of 23 (70%) program directors or their designees returned our survey. In general, abortion-related topics received less coverage than contraception, ectopic pregnancy management and miscarriage management. Fifty-six percent of respondents reported that their program did not offer information about first-trimester abortion procedures and/or post-abortion care in the didactic curriculum. Respondents expressed interest in incorporating mifepristone/misoprostol into NP education and training. Reproductive health issues receive uneven and often inadequate curricular coverage in Canadian NP programs. Identifying avenues to expand education and training on abortion appears warranted. Embarking on curricular reform efforts is especially important given the upcoming introduction of mifepristone into the Canadian health system for early abortion. Our findings draw attention to the need to integrate abortion-related content into NP education and training programs. The approval of Mifegymiso® may provide a window of opportunity to engage in curriculum reform efforts across the health professions in Canada. Copyright

    Several environmental survey design issues are discussed and illustrated with surveys designed by Research Triangle Institute statisticians. Issues related to sampling and nonsampling errors are illustrated for indoor air quality surveys, radon surveys, pesticide surveys, and occupational and personal exposure surveys. Sample design issues include the use of auxiliary information (e.g. for stratification), and sampling in time. We also discuss the reduction and estimation of nonsampling errors, including nonresponse and measurement bias

    Cosmetic plants and their uses have often been neglected in ethnobotanical surveys which focus mainly on plants with medicinal or food uses. Thus, this survey was carried out to specifically investigate cosmetics in a small community and to establish a cosmetopoeia, based on the model of pharmacopoeia for medicinal plants. The geographic spread of the survey covered the Marquesas Islands, one of the five archipelagos of French Polynesia (Pacific Ocean). This archipelago was also recently investigated for its pharmacopoeia. This survey is based on individual interviews of Marquesan informants on the islands of Tahiti (Society archipelago) and Nuku Hiva (Marquesas archipelago). The methodological approach was semi-directive with open-ended questions based on cosmetic criteria (application area, cosmetic use, plant). Before each interview, researchers and the informant signed a Prior Informed Consent (PIC). Quantitative analyses were performed using basic statistics and the indice of Fidelity Level (FL). Twenty-eight informants from five of the six inhabited Marquesan islands were interviewed and yielded more than 500 cosmetic recipes. Marquesan cosmetopoeia included 79 plant taxa, of which 5% are Marquesan endemics, 23% are indigenous, 28% are Polynesian introductions and 44% are modern introductions. Among the introduced species, half were cultivated whereas the other half were weedy species. Most of the plants were abundant and only eight species were considered rare, of which four were Marquesan endemics. Main cosmetic plants were identified through informant citations and fidelity levels, and included Calophyllum inophyllum, Cananga odorata, Citrus aurantiifolia, Cocos nucifera, Curcuma longa, Gardenia taitensis, Mentha spp., Ocimum basilicum, Rauvolfia nukuhivensis and Santalum insulare var. marchionense. The most referred application areas were skin, hair and private parts whereas the main cosmetic uses were perfume, hydration, medicinal care and healing

    Gestational diabetes mellitus (GDM) is one of the most common pregnancy disorders; however, if well managed, women with GDM experience similar pregnancy outcomes to those without. Currently, there is limited evidence on actual management practices across Australia or how multidisciplinary teams interact to optimise care. To examine the current screening, diagnostic, task and role perceptions and management practices, as reported by members of the GDM multidisciplinary team. A 64-item electronic survey containing multiple choice, Likert scale and open-ended questions was developed for this cross-sectional observational study and advertised through health professional organisations and Queensland Health facilities in May and June, 2017. The 183 survey respondents included 45 diabetes educators, 43 dietitians, 21 endocrinologists/diabetes specialists, 14 obstetricians and 21 midwives. Although almost 90% reported using updated diagnostic guidelines, less than two-thirds used GDM management guidelines. While 68% reported using the same blood glucose targets for GDM management, there was variation to what criteria prompted the commencement of medication to control blood glucose levels. There was a good consensus concerning the health professional responsible for tasks such as medical nutrition therapy, gestational weight gain and self-blood glucose monitoring education and ultrasound use. Other tasks appeared to be the role of almost any member of the GDM multidisciplinary team. The survey results indicate there is a need for consistent evidence on how to best manage GDM and that role identity, access to specialist knowledge and best practice need to be clearly defined within GDM models of care. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

  9. Development of an Introductory Oceanography Concept Inventory Survey

    2008-12-01

    Concept inventories are one type of assessment that can be used to evaluate whether a student has an accurate and working knowledge of a specific set of concepts. Although such assessment tools have been developed in astronomy, biology, chemistry, engineering, fluid mechanics, geology, and physics, none has been available. Our development of an Introductory Oceanography Concept Inventory Survey (IO-CIS) serves to fill this gap. Much of the development of the IO-CIS utilized students enrolled in the Spring 2008 Introduction to Oceanography course taught at the University of Colorado at Boulder. The first step in the development of IO-CIS involved the identification and selection of the critical concepts to be addressed in the course and the survey. Next, learning goals were defined for each critical concept. These learning goals then provided the basis for framing open-ended questions that were administered to students in pre-module in-class Concept Inventory Exercises (CIEs). These open-ended questions each underwent validation and revision with expert and novice input prior to being administered in a CIE. Each CIE comprised 4-5 open-ended questions, which each contained 1-4 parts. During the semester, 4 different CIEs were administered, with the number of respondents for each CIE ranging from 57-134. Student responses were then binned according to misconceptions and alternate conceptions, tallied, and "distractors" were written based on the most popular bins using the same language employed by students in their responses. Student responses were also used as part of the validation process to ensure that the questions were interpreted by students in the manner intended. Student responses were also used as a basis to discard particular questions from inclusion in the overall IO-CIS. After the initial IO-CIS questions and distractors had been designed as described above, 23 one-on-one student interviews were conducted as part of the validation process. As a result of

    Multidisciplinary care is advocated as best practice in cancer care. Relatively little is documented about multidisciplinary team (MDT) meeting functioning, decision making and the use of evidence to support decision making in Australia. This descriptive study aimed to examine team functioning, the role of team meetings and evidence use in MDTs whose institutions are members of Sydney Catalyst Translational Cancer Research Centre. We designed a structured 40-item survey instrument about topics that included meeting purpose, organization, resources and documentation; caseload estimates; use of evidence and quality assurance; patient involvement and supportive care needs; and open-ended items about the MDTs strengths and weaknesses. Participants were invited to participate via email and the survey was administered online. Data were analyzed using descriptive and comparative statistics. Thirty-seven MDTs from seven hospitals participated (100% response) and represented common (70%) and rare tumor groups (30%). MDT meeting purpose was reported as treatment (100%) or diagnostic decision making (88%), or for education purposes (70%). Most MDTs based treatment decisions on group consensus (92%), adherence to clinical practice guidelines (57%) or other evidence-based medicine sources (33%). The majority of MDTs discussed only a proportion of new patients at each meeting emphasizing the importance of educational aspects for other cases. Barriers exist in the availability of data to enable audit and reflection on evidence-based practice. MDT strengths included collaboration and quality discussion about patients. MDT meetings focus on treatment decision making, with group consensus playing a significant role in translating research evidence from guidelines into clinical decision making. With a varying proportion of patients discussed in each MDT meeting, a wider audit of multidisciplinary care would enable more accurate assessments of whether treatment recommendations are in

    To systematically assess views on contributions and future activities for long-term research in ecology and evolution (LTREE), we conducted and here provide data responses and associated metadata for a survey of ecological and evolutionary scientists. The survey objectives were to: (1) Identify and prioritize research questions that are important to address through long-term, ecological field experiments; and (2) understand the role that these experiments might play in generating and applying ecological and evolutionary knowledge. The survey was developed adhering to the standards of the American Association for Public Opinion Research. It was administered online using Qualtrics Survey Software. Survey creation was a multi-step process, with questions and format developed and then revised with, for example, input from an external advisory committee comprising senior and junior ecological and evolutionary researchers. The final questionnaire was released to ~100 colleagues to ensure functionality and then fielded 2 d later (January 7 th , 2015). Two professional societies distributed it to their membership, including the Ecological Society of America, and it was posted to three list serves. The questionnaire was available through February 8th 2015 and completed by 1,179 respondents. The distribution approach targeted practicing ecologists and evolutionary biologists in the U.S. Quantitative (both ordinal and categorical) closed-ended questions used a predefined set of response categories, facilitating direct comparison across all respondents. Qualitative, open-ended questions, provided respondents the opportunity to develop their own answers. We employed quantitative questions to score views on the extent to which long-term experimental research has contributed to understanding in ecology and evolutionary biology; its role compared to other approaches (e.g., short-term experiments); justifications for and caveats to long-term experiments; and the relative importance

    To identify relevant aspects of functioning, disability, and contextual factors for adults with hearing loss (HL) from hearing health professional perspective summarized using the ICF classification as reference tool. Internet-based cross-sectional survey using open-ended questions. Responses were analysed using a simplified content analysis approach to link concept to ICF categories according to linking rules. Hearing health professionals (experts) recruited through e-mail distribution lists of professional organizations and personal networks of ICF core set for hearing loss steering committee members. Stratified sampling according to profession and world region enhanced the international and professional representation. Sixty-three experts constituted the stratified sample used in the analysis. A total of 1726 meaningful concepts were identified in this study, resulting in 209 distinctive ICF categories, with 106 mentioned by 5% or more of respondents. Most categories in the activities & participation component related to communication, while the most frequent environmental factors related to the physical environment such as hearing aids or noise. Mental functions, such as confidence or emotional functions were also frequently highlighted. More than half (53.3%) of the entire ICF classification categories were included in the expert survey results. This emphasizes the importance of a multidimensional tool, such as the ICF, for assessing persons with hearing loss.

    The study gives a survey of the factors most frequently mentioned in the literature as factors likely to adversely affect a pregnancy. One essential aspect is the discussion of those factors that can be counted among the causes of malformations, as among others, prenatal radiation exposure. The study prepared within the framework of the research project 'Radiobiological environmental monitoring in Bavaria' is intended to serve as a basis for a retrospective and prospective evaluation of infant mortality, perinatal conditions and occurrence of malformations in Bavaria, with the principal idea of drawing up an environment - related health survey. The study therefore, in addition to ionizing radiation also takes into account other detectable risks within the ecologic context, as e.g. industrial installations, refuse incineration plants or waste dumps, or urbanity.

    2016-11-01

    Full Text Available Introduction: The extent to which health sciences librarians are engaged in research is a little-studied question. This study assesses the research activities and attitudes of Medical Library Association (MLA members, including the influence of work affiliation. Methods: An online survey was designed using a combination of multiple-choice and open-ended questions and distributed to MLA members. Responses were analyzed using descriptive statistics, content analysis, and significance testing. The authors used statistical tools and categorized openended question topics by the constant comparative method, also applying the broad subject categories used in a prior study. Pearson’s chi-square analysis was performed on responses to determine significant differences among respondents employed in three different institutional environments. Results: Analysis showed that 79% of respondents read research articles at least once a month; 58% applied published research studies to practice; 44% had conducted research; 62% reported acting on research had enhanced their libraries; 38% had presented findings; and 34% had authored research articles. Hospital librarians were significantly less likely than academic librarians to have participated in research activities. Highly ranked research benefits, barriers, and competencies of health sciences librarians are described. Conclusions: Findings indicate that health sciences librarians are actively engaged in research activities. Practice implications for practitioners, publishers, and stakeholders are discussed. Results suggest that practitioners can use published research results and results from their own research to affect practice decisions and improve services. Future studies are needed to confirm and extend these findings, including the need for intervention studies to increase research and writing productivity.

    The United States Geological Survey (USGS) has contracted with the Institute of Oceanographic Sciences (IOS) to charter the research vessel Farnella. The project is to map the ocean floor at depths greater than 500 m along the recently established United States Exclusive Economic Zone (EEZ). The short range objectives include obtaining seafloor contours along the deep sea thermal spring zones in the Pacific Ocean basin. Should any of the zones prove economic for their sulfide mineral deposits, the charts should be of value to industry for years to come.

    The role of a dentist is not only to examine and treat the oral diseases but also to assist the legal authorities by means of its branch-forensic odontology. Through forensic odontology, a dentist plays a very important role in crime investigation of any type. To analyze the knowledge, awareness, and interest of forensic odontology among the dental teaching staff who are working in the dental colleges within the Delhi NCR. A questionnaire of 12 questions (both open-ended and close-ended) was prepared and the survey was conducted with 200 dental teaching staff. A sufficient knowledge but poor awareness and interest among the dental teaching staff was observed. The study highlighted that although dental teaching staff themselves have sound knowledge regarding forensic odontology, their awareness and interest need to be upgraded on a regular basis. The success of acquiring such extensive knowledge would be valid if better job opportunities in these fields would be increased.

    Clinical skill development is essential to nurse education. Clinical skills are frequently taught in higher education institutions using clinical simulation. It is unclear if clinical skills are subsequently consolidated and developed in clinical placements. The aim of this survey was to evaluate pre-registration student nurses perceptions of the frequency of opportunities to practise, the level of supervision and assessment of, clinical skills in their clinical placements. This was a cross-sectional survey design using an online, self-report questionnaire including a Likert-type scale and open ended comments. Four hundred and twenty one students, from all year groups, from a university in the south of England on a wide variety of clinical placements participated. Participants evaluated the frequency of opportunity to practise, level of supervision and assessment of and feedback on performance of specific clinical skills. Clinical skills evaluated were measurement of vital signs, aseptic non-touch technique, assisting with eating and drinking, and assisting with comfort and hygiene. Data were analysed utilising Statistical Package for the Social Sciences Version 19. The frequency of opportunities to practise skills in clinical placement was variable with some participants reporting that they never had opportunity to practise essential skills. Similarly the level of supervision and assessment was also inconsistent suggesting that participants frequently practised clinical skills unsupervised without being assessed as competent. Inconsistencies in clinical skill development may lead to graduates who are not work ready and as a result, insufficient clinical competence potentially leads to unsafe practice and poor patient care.

    The current cross-cultural study investigated grief reactions of bereaved individuals following the death of a pet. We used qualitative methodology to compare, analyze, and report responses of U.S. and French Canadian participants to the last open-ended question on our online pet loss survey. We explored the degree to which our data illustrated pet loss as disenfranchised grief and asked whether there are differences and commonalities in the expression of grief between the two samples. Four major themes emerged: lack of validation and support; intensity of loss; nature of the human pet relationship; and continuing bonds. Findings confirm that, for both the U.S. and French Canadian participants, pet loss is often disenfranchised grief and there are ways to facilitate expressions of grief. Many participants wrote that the survey was therapeutic. Our survey allowed participants to express their grief in an anonymous, safe way by serving as empathic bridging and a willingness to help others.

    Full Text Available Joseph S Ross, Katrina L Blount, Jessica D Ritchie, Beth Hodshon, Harlan M Krumholz Center for Outcomes Research and Evaluation, Yale-New Haven Hospital, New Haven, CT, USA Background: In the US, once a medical device is made available for use, several requirements have been established by the US Food and Drug Administration (FDA to ensure ongoing post-market surveillance of device safety and effectiveness. Our objective was to determine how commonly medical device manufacturers initiate post-market clinical studies or augment FDA post-market surveillance requirements for higher-risk devices that are most often approved via the FDA's pre-market approval (PMA pathway. Methods and results: We conducted a cross-sectional survey of 47 manufacturers with operations in California, Minnesota, and Massachusetts who market devices approved via the PMA pathway. Among 22 respondents (response rate =47%, nearly all self-reported conducting post-market clinical research studies, commonly between 1 and 5; only 1 respondent reported never conducting post-market clinical research studies. While manufacturers most often engaged in these studies to satisfy FDA requirements, other reasons were reported, including performance monitoring and surveillance and market acceptance initiatives. Risks of conducting and not conducting post-market clinical research studies were described through open-ended response to questions. Conclusion: Medical device manufacturers commonly initiate post-market clinical studies at the request of the FDA. Clinical data from these studies should be integrated into national post-market surveillance initiatives. Keywords: FDA, PMA pathway, post-market surveillance

    As demand for nurses and other health professionals continues to outstrip supply it is important to understand what motivates individuals to join a non-medical health profession. The objectives of this study were to investigate students' reasons for choosing a particular nursing specialism, midwifery or other non-medical health profession, and to compare motivation factors across professions, gender, age, level of award, prior qualifications, prior experience and over time. A prospective follow-up study collected survey responses at the beginning and end of pre-qualifying professional programmes. The study took place in one large United Kingdom faculty. The study participants were 775 first-year students undertaking non-medical health professional programmes and 393 qualifying students. An open-ended question was included in a self-completed questionnaire administered at entry and at qualification. Content analysis identified themes. Altruism was the most frequently cited reason for wishing to join a non-medical health profession, followed by personal interest/abilities, professional values/rewards, and prior experience of the area. Students entering nursing were less likely to cite an altruistic motivation than those entering other non-medical health professions (chi(2)=21.61, df=1, pvalues/rewards (chi(2)=20.38, df=8, p=0.009). Students on degree level programmes were more likely to report altruism than those on diploma level courses (chi(2)=17.37, df=1, pvalues/rewards (chi(2)=6.67, p=0.010) decreased over time. Findings suggest that although a service orientation remains a key factor in choosing nursing, students also look for a career which matches their interests and attributes, as well as offering professional values and rewards. Nursing may be in danger of losing service orientated recruits to other non-medical health professions.

    Full Text Available Introduction: Most human orofacial infections originate from odontogenic infections and prescribing antibiotics has become a ubiquitous phenomenon. The World Health Organization (WHO has recognized the inappropriate, indiscriminate, and irrational use of antibiotics leading to antibiotic resistance as a global problem. Objective: The objective of this survey is to compare the antibiotic prescription pattern and the awareness of antibiotic resistance among Bachelor of Dental Surgery (BDS practitioners and pediatric dentists. Materials and methods: A hundred BDS practitioners and 100 pediatric dentists included in the study were given a questionnaire containing both open-ended and closed-ended questions. The questionnaire comprised information pertaining to antibiotic prescription for most common oral conditions, commonly prescribed antibiotics, their dosage, etc. Results: The majority of the practitioners prescribed antibiotics for managing oral diseases. On comparing the prescription patterns between the BDS practitioners and pediatric dentists, there was an overprescription in the BDS group for many conditions, which was statistically significant. Amoxicillin was the most commonly prescribed drug in both the groups. In the presence of an anaerobic infection, the most preferred drug was a combination of amoxicillin and clavulanic acid with metronidazole. With regard to the duration of antibiotic prescription, 74% BDS practitioners prescribed antibiotics as a 3-day course and 60% pediatric dentists resorted to a 5-day course, which was statistically significant. The awareness regarding antibiotic prophylaxis and antibiotic resistance was found to be adequate in both the groups. However, there was a general lack of awareness with regard to the guidelines for antibiotic prescribing in both the groups. Conclusion: Practitioners should prescribe antibiotics in accordance with the guidelines to curb antibiotic resistance, an emerging public health

    OBJECTIVE--To determine the views of directors of public health on the importance of housing for public health and their departments' and health authorities' participation in housing issues. DESIGN--Postal self administered questionnaire survey. SETTING--All district health authorities in England and health boards in Wales, Scotland, and Northern Ireland. SUBJECTS--All 221 district directors of public health in England and chief administrative medical officers in Wales, Scotland, and Northern Ireland. MAIN OUTCOME MEASURE--Response to questionnaire consisting of fixed and open ended questions on housing issues. RESULTS--The response rate was 89% (196/221). Housing was perceived as a major health problem by 33% (65/196) of directors. Positive responses were most likely from inner city districts. In 47% (93/196) of departments there was a formal time commitment to housing issues with a median time of one session/week (range one per month to 10 per week). The main function was allocation of medical priority for public sector rehousing. Overall, 73% (144/196) reported some participation in this process. Reported participation in joint care planning and links with non-statutory housing organisations were uncommon. 53% (104/196) of directors had included housing issues in their annual health report. In 16% (32/196) of districts specific services for the homeless had been set up. CONCLUSIONS--Although concern about the impact of current housing policy on public health was shown by a substantial number of directors, the main activity was still allocation of medical priority despite a background of increasing housing need and homelessness. The underlying need is for greater advocacy to produce a healthy housing policy for all, and the annual public health report could be used to promote this objective. PMID:1995137

    Full Text Available Abstract Background National public health associations (PHAs are key partners with governments and communities to improve, protect and promote the public’s health. Governance and organizational capacity are among the key determinants of a PHA’s effectiveness as an advocate for appropriate public health policies and practice. Methods During 2014, the World Federation of Public Health Associations (WFPHA conducted an on-line survey of its 82 PHA members, to identify the state of organizational governance of national public health associations, as well as the factors that influence optimal organizational governance. The survey consisted of 13 questions and focused on the main elements of organizational governance: cultivating accountability; engaging stakeholders; setting shared direction; stewarding resources; and, continuous governance enhancement. Four questions included a qualitative open-ended response for additional comments. The survey data were analyzed using Microsoft Excel. The qualitative data was analyzed using thematic content analysis Results Responses were received from 62 PHAs, constituting a 75.6 % response rate. The two most important factors that support governance effectiveness were a high degree of integrity and ethical behavior of the PHA’s leaders (77 % and the competence of people serving on the PHA’s governing body (76 %. The lack of financial resources was considered as the most important factor that negatively affected organizational governance effectiveness (73 %. The lack of mentoring for future PHA leaders; ineffective or incompetent leadership; lack of understanding about good governance practices; and lack of accurate information for strategic planning were identified as factors influencing PHA governance effectiveness. Critical elements for PHA sustainability included diversity, gender-responsiveness and inclusive governance practices, and strategies to build the future generation of public health

    Cluster randomized trials (CRTs) complicate the interpretation of standard research ethics guidelines for several reasons. For one, the units of allocation, intervention, and observation often may differ within a single trial. In the absence of tailored and internationally accepted ethics guidelines for CRTs, researchers and research ethics committees have no common standard by which to judge ethically appropriate practices in CRTs. Moreover, lack of familiarity with and consideration of the unique features of the CRT design by research ethics committees may cause difficulties in the research ethics review process, and amplify problems such as variability in the requirements and decisions reached by different research ethics committees. We aimed to characterize research ethics review of CRTs, examine investigator experiences with the ethics review process, and assess the need for ethics guidelines for CRTs. An electronic search strategy implemented in MEDLINE was used to identify and randomly sample 300 CRTs published in English language journals from 2000 to 2008. A web-based survey with closed- and open-ended questions was administered to corresponding authors in a series of six contacts. The survey response rate was 64%. Among 182 of 285 eligible respondents, 91% indicated that they had sought research ethics approval for the identified CRT, although only 70% respondents reported research ethics approval in the published article. Nearly one-third (31%) indicated that they have had to meet with ethics committees to explain aspects of their trials, nearly half (46%) experienced variability in the ethics review process in multijurisdictional trials, and 38% experienced negative impacts of the ethics review process on their trials, including delays in trial initiation (28%), increased costs (10%), compromised ability to recruit participants (16%), and compromised methodological quality (9%). Most respondents (74%; 95% confidence interval (CI): 67%-80%) agreed or

    This chapter deals with the radiotherapy and cytotoxic chemotherapy of the malignant lymphomas. Included within this group are Hodgkin's disease, non-Hodgkin's lymphoma, mycosis fungoides, and chronic lymphatic leukaemia. A further section deals with the myeloproliferative disorders, including granulocytic leukaemia, polycythaemia vera, and primary thrombocythaemia. Excluded are myeloma and reticulum cell sarcoma of bone and acute leukaemia. With regard to Hodgkin's disease, the past 25 years have seen general recognition of the curative potential of radiotherapy, at least in the local stages, and, more recently, awareness of the ability to achieve long-term survival after combination chemotherapy in generalised or in recurrent disease. At the same time the importance of staging has become appreciated and the introduction of procedures such as lymphography, staging laparotomy, and computer tomography (CT) has enormously increased its reliability. Advances have not been so dramatic in the complex group of non-Hodgkins's lymphomas, but are still very real

    This study aimed to examine levels of social anxiety, anxiety and depression reported by people with alopecia as a result of a dermatological condition and associations with wig use. The study also sought to report on experiences of wearing wigs in social situations and the relationship with social confidence. A cross-sectional survey was sent by email to the Alopecia UK charity mailing list and advertised on social media. Inclusion criteria were a diagnosis of alopecia, aged 13 or above and sufficient English to complete the survey. Exclusion criteria included experiencing hair loss as a result of chemotherapy treatment or psychological disorder. Participants (n=338) were predominantly female (97.3%), Caucasian (93.5%) and aged between 35 and 54 years (49.4%) with a diagnosis of alopecia areata (82.6%). The Social Phobia Inventory measured symptoms of social anxiety, and the Hospital Anxiety and Depression Scale was used to measure symptoms of anxiety and depression. Survey questions were designed to measure the use of wigs. Open-ended questions enabled participants to comment on their experiences of wearing wigs. Clinically significant levels of social anxiety (47.5%), anxiety (35.5%) and depression (29%) were reported. Participants who reported worries about not wearing a wig reported significantly higher levels of depression: t(103)=3.40, p≤0.001; anxiety: t(109)=4.80, p≤0.001; and social anxiety: t(294)=3.89, p≤0.001. Wearing wigs was reported as increasing social confidence; however, the concealment it afforded was also reported as both reducing fear of negative evaluation and maintaining anxiety. Overall, 46% of participants reported that wearing a wig had a positive impact on their everyday life with negative experiences related to fears of the wig being noticed. Psychological interventions alongside wig provision would be beneficial for people living with alopecia. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

    Many, thanks to the hundreds of people who took the time to reply to the CERN Courier readership survey questionnaire published in our May issue. Bringing out a monthly journal is a lonely business. Issue after issue goes out, and the only response is when there's an occasional factual error. Send out a readership survey and a faint echo comes back. Most striking was the sheer enthusiasm of the replies. Despite the current erosion of support in the US (see page 2), subatomic physics has significant world-wide box-office appeal. Most important was to find out who our readers are. 61% of the replies came from Europe, 21% from the USA, 14% from elsewhere, (including the former Soviet Union), and 4% from inside CERN. Not surprisingly, the main audience (37%) is in the high energy physics sector. Then comes teaching (31%), followed closely by accelerators operations and design (12%) and industry (11%). Apart from detailed breakdowns of readership and feedback on the journal's content and style, the replies revealed several major features. Firstly, the CERN Courier is widely read and appreciated. There are a lot of people outside the immediate research field who want to keep broadly up to date with the latest developments in high energy physics and related fields, without getting too involved in details. It was gratifying to receive replies from far-flung places (Nepal, Indonesia,....), and learn how much distant readers appreciate getting such regular information. 'It helps us feel part of the world scene,' was a typical such reply, from Australia. Despite jet airplanes, fax and electronic mail, our planet is still big

    Competency in evidence-based practice (EBP) is a requirement for graduate nurses. Despite a growing body of research exploring the EBP profiles of students, little research has explored the EBP profiles of nurse educators. To explore: the differences/similarities in the EBP profiles of US and UK clinical and academic faculty; the barriers nurse educators experience when teaching EBP; the impact of postgraduate education on EBP profile and; what nurse educators perceive "success" in implementing and teaching EBP to be. A cross-sectional online survey design was employed. Two Universities delivering undergraduate nursing education in the US and UK, in partnership with large hospital systems, small community hospitals, community settings, and independent sector health organisations. Eighty-one nurse educators working in academic and clinical contexts in the US and UK (US academic=12, US clinical=17, UK academic=9, UK clinical=43) were recruited opportunistically. Participants were emailed a weblink to an online survey, comprising demographic questions, the Evidence-Based Practice Questionnaire and open-ended questions about EBP barriers, facilitators and successes. Quantitative results indicated that academic faculty scored significantly higher on knowledge and skills of EBP, than clinical faculty, but revealed no other significant differences on EBP use or attitudes, or between US and UK professionals. Participants with postgraduate training scored significantly higher on EBP knowledge/skills, but not EBP attitudes or use. Qualitative findings identified key themes relating to EBP barriers and facilitators, including: Evidence-, organisational-, and teaching-related issues. Perceptions of successes in EBP were also described. Nurse educators working in the UK and US face similar EBP barriers to teaching and implementation, but view it positively and use it frequently. Clinical staff may require extra support to maintain their EBP knowledge and skills in

    Japan's stagnant economy has produced increasing income disparities, and the effect of poverty on health and health-care utilization is a significant issue. Co-payments could be a trade-off for patients when seeking medical care and limit health-care utilization. We sought primary care physicians' experiences in dealing with financially deprived patients and their perspectives about reducing co-payments by low-income patients. We used a convergent mixed-methods approach in a mail survey; it was distributed to 1989 primary care physicians practicing in areas with the highest proportions of socially disadvantaged individuals in Tokyo. The survey items included an open-ended question, seeking the participants' perspectives about reducing co-payments by low-income patients from the current 30%, and closed questions, asking their experience of patient behavior related to financial burdens during the previous 6 months. We analyzed the responses of 365 physicians. Sixty-two percent of the primary care physicians agreed with lowering co-payments for financially deprived patients; however, the remainder disagreed or were uncertain. Those who disagreed were less likely to have experienced patient behavior related to financial burdens. The participants suggested challenges and potential measures for reducing co-payments by low-income patients in light of tight governmental financial resources and rapidly increasing health-care expenditures in Japan. The physicians were also concerned about the moral hazard in health-care utilization among patients receiving social welfare who obtain care at no cost. From their experience in having dealt with low-income patients, the majority of physicians were positive about lowering co-payments by such patients; the remainder were negative or uncertain. It may be necessary to raise awareness of patients' socioeconomic status among primary care physicians as a possible deterrent for seeking care. To maintain health-care equity, policy makers

    Nutrition leaders surmised graduate medical nutrition education was not well addressed because most medical and surgical specialties have insufficient resources to teach current nutrition practice. A needs assessment survey was constructed to determine resources and commitment for nutrition education from U.S. graduate medical educators to address this problem. An online survey of 36 questions was sent to 495 Accreditation Council for Graduate Medical Education (ACGME) Program Directors in anesthesia, family medicine, internal medicine, pediatrics, obstetrics/gynecology, and general surgery. Demographics, resources, and open-ended questions were included. There was a 14% response rate (72 programs), consistent with similar studies on the topic. Most (80%) of the program directors responding were from primary care programs, the rest surgical (17%) or anesthesia (3%). Program directors themselves lacked knowledge of nutrition. While some form of nutrition education was provided at 78% of programs, only 26% had a formal curriculum and physicians served as faculty at only 53%. Sixteen programs had no identifiable expert in nutrition and 10 programs stated that no nutrition training was provided. Training was variable, ranging from an hour of lecture to a month-long rotation. Seventy-seven percent of program directors stated that the required educational goals in nutrition were not met. The majority felt an advanced course in clinical nutrition should be required of residents now or in the future. Nutrition education in current graduate medical education is poor. Most programs lack the expertise or time commitment to teach a formal course but recognize the need to meet educational requirements. A broad-based, diverse universal program is needed for training in nutrition during residency. © 2015 American Society for Parenteral and Enteral Nutrition.

    Survey research is a unique methodology that can provide insight into individuals' perspectives and experiences and can be collected on a large population-based sample. Specifically, in plastic surgery, survey research can provide patients and providers with accurate and reproducible information to assist with medical decision-making. When using survey methods in research, researchers should develop a conceptual model that explains the relationships of the independent and dependent variables. The items of the survey are of primary importance. Collected data are only useful if they accurately measure the concepts of interest. In addition, administration of the survey must follow basic principles to ensure an adequate response rate and representation of the intended target sample. In this article, the authors review some general concepts important for successful survey research and discuss the many advantages this methodology has for obtaining limitless amounts of valuable information.

    This paper provides a brief history of Canadian health surveys and a review of health or health-related surveys from the first national household survey in 1950/51 to the present time. Surveys have evolved from collecting information on health care utilization, health status and some risk behaviours to a wider range of health determinants following the 1974 Lalonde report. In addition to the occasional cross-sectional surveys, there are periodic surveys, longitudinal surveys, school-based surveys and surveys based on subgroups in the population or specific topic areas. The survey review is presented in the following four tables: Table 1 summarizes national surveys including such information as the date(s) and frequency of data collection, topic areas, target population, sample size and response rate for each survey; Table 2 provides the same information for provincial surveys; both tables point to Table 3, which supplements the previous information with survey sponsors and contacts; Table 4 provides similar information for commercial surveys. This reference, which will be updated periodically, is intended to act as a source of information and support in the development of new surveys.

    Full Text Available Abstract Background In Quebec, the influenza A (H1N1 pandemic was managed using a top-down style that left many involved players with critical views and frustrations. We aimed to describe physicians' perceptions - infectious diseases specialists/medical microbiologists (IDMM and public health/preventive medicine specialists (PHPMS - in regards to issues encountered with the pandemics management at the physician level and highlight suggested improvements for future healthcare emergencies. Methods In April 2010, Quebec IDMM and PHPMS physicians were invited to anonymously complete a web-based learning needs assessment. The survey included both open-ended and multiple-choice questions. Descriptive statistics were used to report on the frequency distribution of multiple choice responses whereas thematic content analysis was used to analyse qualitative data generated from the survey and help understand respondents' experience and perceptions with the pandemics. Results Of the 102 respondents, 85.3% reported difficulties or frustrations in their practice during the pandemic. The thematic analysis revealed two core themes describing the problems experienced in the pandemic management: coordination and resource-related difficulties. Coordination issues included communication, clinical practice guidelines, decision-making, roles and responsibilities, epidemiological investigation, and public health expert advisory committees. Resources issues included laboratory resources, patient management, and vaccination process. Conclusion Together, the quantitative and qualitative data suggest a need for improved coordination, a better definition of roles and responsibilities, increased use of information technologies, merged communications, and transparency in the decisional process. Increased flexibility and less contradiction in clinical practice guidelines from different sources and increased laboratory/clinical capacity were felt critical to the proper

    Full Text Available Screening for atrial fibrillation (AF in primary care has been recommended; however, the views of healthcare professionals (HCPs are not known. This study aimed to determine the opinions of HCP about the feasibility of implementing screening within a primary care setting.A cross-sectional mixed methods census survey of 418 HCPs from 59 inner-city practices (Nottingham, UK was conducted between October-December 2014. Postal and web-surveys ascertained data on existing methods, knowledge, skills, attitudes, barriers and facilitators to AF screening using Likert scale and open-ended questions. Responses, categorized according to HCP group, were summarized using proportions, adjusting for clustering by practice, with 95% C.Is and free-text responses using thematic analysis.At least one General Practitioner (GP responded from 48 (81% practices. There were 212/418 (51% respondents; 118/229 GPs, 67/129 nurses [50 practice nurses; 17 Nurse Practitioners (NPs], 27/60 healthcare assistants (HCAs. 39/48 (81% practices had an ECG machine and diagnosed AF in-house. Non-GP HCPs reported having less knowledge about ECG interpretation, diagnosing and treating AF than GPs. A greater proportion of non-GP HCPs reported they would benefit from ECG training specifically for AF diagnosis than GPs [proportion (95% CI GPs: 11.9% (6.8-20.0; HCAs: 37.0% (21.7-55.5; nurses: 44.0% (30.0-59.0; NPs 41.2% (21.9-63.7]. Barriers included time, workload and capacity to undertake screening activities, although training to diagnose and manage AF was a required facilitator.Inner-city general practices were found to have adequate access to resources for AF screening. There is enthusiasm by non-GP HCPs to up-skill in the diagnosis and management of AF and they may have a role in future AF screening. However, organisational barriers, such as lack of time, staff and capacity, should be overcome for AF screening to be feasibly implemented within primary care.

    Exoskeleton technology has potential benefits for wheelchair users' health and mobility. However, there are practical barriers to their everyday use as a mobility device. In particular, challenges related to travelling longer distances and transitioning between using a wheelchair and exoskeleton walking may present significant deterrents to regular exoskeleton use. In an effort to remove these barriers, a combined exoskeleton-wheelchair concept ('COMBO') has been proposed, which aims to achieve the benefits of both these mobility technologies. Given the inherent importance of including user-stakeholder opinions when designing an assistive technology solution, a study was undertaken to explore the perspectives of wheelchair users and healthcare professionals on the proposed conceptual design of the COMBO. An online survey with quantitative and qualitative components was conducted with wheelchair users and healthcare professionals working directly with individuals with mobility impairments. Respondents rated whether they would use or recommend a COMBO for four potential reasons. Nine design features were rated and compared in terms of their importance. Content analysis was used to analyze data from an open-ended question regarding additional perceptions about using or recommending a COMBO. A total of 481 survey responses were analyzed, 354 from wheelchair users and 127 from healthcare professionals. Potential health benefits was the most highly rated reason for potential use or recommendation of a COMBO. Of the 9 design features, 2 had a median rating of very important: inclusion of a fall-protection mechanism, and the ability for the operator to use their hands while standing. Qualitative findings indicated that health and physical benefits, use for daily life activities, and psychosocial benefits were important considerations in whether to use or recommend the COMBO. This study captures the opinions and perspectives of two stakeholder groups for an exoskeleton

    Full Text Available Abstract Background Although the mandate of recreational facilities is to enhance well-being, many offer foods inconsistent with recommendations for healthy eating. Little is known regarding recreational facility food environments and how they might be improved, as few studies exist. The Alberta Nutrition Guidelines for Children and Youth (ANGCY are intended to ensure access to healthy food choices in schools, childcare and recreational facilities. This study investigated awareness, adoption and implementation of the ANGCY among recreational facilities in Alberta, Canada, one year following their release. Methods A cross-sectional telephone survey was conducted from June - December, 2009 (n = 151 with managers of publicly funded recreational facilities that served food. The questionnaire included 10 closed and 7 open ended questions to assess the organizational priority for healthy eating, awareness, adoption and implementation of the ANGCY. Chi-squared tests examined quantitative variables, while qualitative data were analysed using directed content analysis. Greenhalgh's model of diffusion of complex innovations within health service organizations constituted the theoretical framework for the study. Results One half of respondents had heard of the ANGCY, however their knowledge of them was limited. Although 51% of facilities had made changes to improve the nutritional quality of foods offered in the past year, only a small fraction (11% of these changes were motivated by the ANGCY. At the time of the survey, 14% of facilities had adopted the ANGCY and 6% had implemented them. Barriers to adoption and implementation were primarily related to perceived negative attributes of the ANGCY, the inner (organizational context, and negative feedback received during the implementation process. Managers strongly perceived that implementing nutrition guidelines would limit their profit-making ability. Conclusions If fully adopted and implemented, the ANGCY

    Direct-to-consumer advertising (DDTCA) of medications, a marketing tool used by the pharmaceutical industry to increase patient awareness of products, affects both consumer behavior and, ultimately, physician prescribing practices. Billions of dollars are budgeted each year for DTCA, and its influence is far-reaching. However, little information is available about patient-initiated physician interactions in which television-bbased DTCA has played a role in consumer behavior. The objective of this study was to explore the influence of television-based DTCA on treatment changes in patient-initiated medication use. A 68-item survey instrument consisting of dichotomous, multiple-choice, and open-ended questions was constructed and sent to a convenience sample of US residents during 3 consecutive months ending in February 2005. The survey, which was accessed through an Internet link provided in the e-mail, was designed to capture data about patient perceptions and behaviors regarding television-based DTCA of prescription medications used for seasonal allergy and asthma as well as demographic information. Inferential and descriptive analyses were performed. Key tests included Crosstabs analysis and normal approximation to the binomial test with the z score. Surveys were sent to 2500 individuals. A total of 427 valid surveys were returned for a 17.1% response rate. Of the 402 respondents (94.1%) who stated that they had seen DTCA for seasonal allergy medication, 50 (12.4%) said they had discussed the advertised medication with their physician and 22 of those discussions (44.0%) resulted in a change in treatment. Three hundred forty-two respondents (80.1%) stated that they had viewed DTCA for prescription asthma medications, and 23 of those respondents (6.7%) said that they had discussed the brand of asthma medication viewed on television with their physician. Those discussions resulted in a change in treatment for 9 respondents (39.1%). Within th his limited, self

    Sleepio is a proven digital sleep improvement program based on cognitive behavioral therapy techniques. Users have the option to join an online community that includes weekly expert discussions, peer-to-peer discussion forums, and personal message walls. The aim of this study was to conduct an online survey to (1) explore the reasons for deciding to engage with the Sleepio online community, (2) explore the potential benefits arising from engagement with the online community, and (3) identify and describe any problematic issues related to use of the online community. We developed an online survey and posted an invitation to the community discussion forum inviting users to participate. In addition, we sent an email invitation to 970 individuals who had previously or were currently working through the Sleepio program to participate in this study. In total, 100 respondents (70/100, 70% female; mean age 51 years, range 26-82 years) completed the online survey. Most respondents had started Sleepio with chronic sleep problems (59/100, 59% up to 10 years; 35/100, 35% >10 years) and had actively engaged with the online community (85/100, 85%) had made a discussion or wall post). At the time of the survey, respondents had used Sleepio for a median of 12 weeks (range from 3 weeks to 2 years). We analyzed responses to the open-ended questions using thematic analysis. This analysis revealed 5 initial drivers for engagement: (1) the desire to connect with people facing similar issues, (2) seeking personalized advice, (3) curiosity, (4) being invited by other members, and (5) wanting to use all available sleep improvement tools. Advantages of engagement included access to continuous support, a reduced sense of isolation, being part of a nonjudgmental community, personalized advice, positive comparisons with others, encouragement to keep going, and altruism. We found 5 potential disadvantages: design and navigation issues, uncertain quality of user-generated content, negative

    Survey was made on residential waste treatment in Shanghai city. Shanghai city with nearly 13 million registered residents produces on average 10,000-11,000 tons/day residential solid wastes. Such wastes are basically disposed by land filling. A landfill site has a current disposal capacity of 7,500 tons/day, and is scheduled to be expanded up to 9,000 tons/day. Problems of waste disposal in Shanghai city are as follows: transportation of wastes collected in the city by trucks, transportation through transit stations to the landfill site by ships, and high disposal cost. Shanghai Environmental Sanitation Bureau is pursuing researches on recycling of wastes, reduction of wastes and harmless treatment in place of conventional land filling. As the survey result, adoption of complete separate collection of wastes is basically important, and application of the latest technologies such as combustion treatment for every waste, heat use, gasification fusion furnace, and RDF (refuse derived fuel) for coal-firing boilers should be considered. 86 figs., 18 tabs.

    Background Surveys are frequently used to collect data. Although paper surveys are commonly used, online surveys are gaining in popularity, with the inclusion of open-ended questions (OEQs) allowing respondents to freely express their views. Little is known about how Filipino-Australian migrants respond to surveys. There is some concern about the usefulness of OEQs administered to culturally and linguistically diverse migrants, who may have limited capacity to articulate their thoughts in writing. Aim To examine the responses of Filipino-Australian migrants to a survey. Discussion A total of 552 respondents were recruited, of whom 428 (78%) completed the questionnaire online. The overall response rate to the OEQs was 69%, with higher completion rates among those given a paper-based questionnaire and those with university educations. Conclusion Filipino migrants with functional English language skills responded well to the online survey. Paper-based administration elicited more OEQ responses, which is attributed to greater interaction between participants and researchers. Those with university educations may have more capacity to express themselves in English and were therefore more likely to complete the OEQs. Implications for practice The high response rate obtained in this study suggests that among Filipino-Australian migrants who rated their English language skills and educational level highly, the translation of OEQs may not be necessary. This has important implications for resources in research. Face-to-face interaction between participants and researchers is an important strategy for increasing the rates of response to OEQs.

    Since many decades in France, the most important part of ambulatory health care expenditure is represented by drug consumption. By the fact, French patient is indeed the greatest world consumer of pharmaceuticals treatments. Therefore, the regulation authorities by successive strategies, attempt to limit or even restrict market access for new drugs in the health care sector secured by public social insurance coverage. Common objectives are to assess the reimbursement to scientific studies and to fix the price of therapeutics at an acceptable level for both industries and government. New trends try then to determine recently the drug price in a dual approach, as a component of global and effective contract, including performance and outcome. The first diffusion authorization is diffusion concerned, but this concept takes into account the eventual success of new produces in long-term survey. Signed for a fixed period as reciprocal partnership between regulation authorities and pharmaceutics industries, the contract integrates two dimensions of incertitude. The first one is represented by the strategy of new treatments development according to efficacy and adapted price, and the second one is linked to the result of diffusion and determines adapted rules if eventual non-respects of the previous engagement are registered. This paper discusses problems related to this new dimension of incertitude affected by conditional drug prices in market access strategy and the adapted follow-up of new treatment diffusion fixed by "outcome" contract between French regulation administration and pharmaceutics industries in our recent economic context.

    Instruments to assess quality of maternity care in Central and Eastern European (CEE) region are scarce, despite reports of poor doctor-patient communication, non-evidence-based care, and informal cash payments. We validated and tested an online questionnaire to study maternity care experiences among Hungarian women. Following literature review, we collated validated items and scales from two previous English-language surveys and adapted them to the Hungarian context. An expert panel assessed items for clarity and relevance on a 4-point ordinal scale. We calculated item-level Content Validation Index (CVI) scores. We designed 9 new items concerning informal cash payments, as well as 7 new "model of care" categories based on mode of payment. The final questionnaire (N = 111 items) was tested in two samples of Hungarian women, representative (N = 600) and convenience (N = 657). We conducted bivariate analysis and thematic analysis of open-ended responses. Experts rated pre-existing English-language items as clear and relevant to Hungarian women's maternity care experiences with an average CVI for included questions of 0.97. Significant differences emerged across the model of care categories in terms of informal payments, informed consent practices, and women's perceptions of autonomy. Thematic analysis (N = 1015) of women's responses identified 13 priority areas of the maternity care experience, 9 of which were addressed by the questionnaire. We developed and validated a comprehensive questionnaire that can be used to evaluate respectful maternity care, evidence-based practice, and informal cash payments in CEE region and beyond.

    The Research Prioritization Task Force of the National Action Alliance for Suicide Prevention conducted a stakeholder survey including 716 respondents from 49 U.S. states and 18 foreign countries. To conduct a qualitative analysis on responses from individuals representing four main stakeholder groups: attempt and loss survivors, researchers, providers, and policy/administrators. This article focuses on a qualitative analysis of the early-round, open-ended responses collected in a modified online Delphi process, and, as an illustration of the research method, focuses on analysis of respondents' views of the role of life and emotional skills in suicide prevention. Content analysis was performed using both inductive and deductive code and category development and systematic qualitative methods. After the inductive coding was completed, the same data set was re-coded using the 12 Aspirational Goals (AGs) identified by the Delphi process. Codes and thematic categories produced from the inductive coding process were, in some cases, very similar or identical to the 12 AGs (i.e., those dealing with risk and protective factors, provider training, preventing reattempts, and stigma). Other codes highlighted areas that were not identified as important in the Delphi process (e.g., cultural/social factors of suicide, substance use). Qualitative and mixed-methods research are essential to the future of suicide prevention work. By design, qualitative research is explorative and appropriate for complex, culturally embedded social issues such as suicide. Such research can be used to generate hypotheses for testing and, as in this analysis, illuminate areas that would be missed in an approach that imposed predetermined categories on data.

    General internal medicine (GIM) careers are increasingly viewed as challenging and unsustainable. We aimed to assess academic GIM worklife and determine remediable predictors of stress and burnout. We conducted an email survey. Physicians, nurse practitioners, and physician assistants in 15 GIM divisions participated. A ten-item survey queried stress, burnout, and work conditions such as electronic medical record (EMR) challenges. An open-ended question assessed stressors and solutions. Results were categorized into burnout, high stress, high control, chaos, good teamwork, high values alignment, documentation time pressure, and excessive home EMR use. Frequencies were determined for national data, Veterans Affairs (VA) versus civilian populations, and hospitalist versus ambulatory roles. A General Linear Mixed Model (GLMM) evaluated associations with burnout. A formal content analysis was performed for open-ended question responses. Of 1235 clinicians sampled, 579 responded (47 %). High stress was present in 67 %, with 38 % burned out (burnout range 10-56 % by division). Half of respondents had low work control, 60 % reported high documentation time pressure, half described too much home EMR time, and most reported very busy or chaotic workplaces. Two-thirds felt aligned with departmental leaders' values, and three-quarters were satisfied with teamwork. Burnout was associated with high stress, low work control, and low values alignment with leaders (all p teamwork than ambulatory clinicians and fewer hospitalists noted documentation time pressure (both p < 0.001). Key themes from the qualitative analysis were short visits, insufficient support staff, a Relative Value Unit mentality, documentation time pressure, and undervaluing education. While GIM divisions overall demonstrate high stress and burnout, division rates vary widely. Sustainability efforts within GIM could focus on visit length, staff support, schedule control, clinic chaos, and EMR stress.

    Checklists can mitigate a multitude of high-cost mistakes in fields ranging from surgery to aviation. As part of a standard protocol, checklists may provide many benefits, including improved equity and communication among team members and more efficient integration of different processes during complex tasks. Mostly, though, checklists serve as easy, efficient means to remind professionals of what they already know but can easily forget. By improving processes, checklists can reduce procedural errors, miscommunications, and even deaths. Although the stakes of writing a survey are rarely as high as they are for performing surgery or piloting a plane, checklists can improve the quality of surveys in medical education. In this Perspective, the authors propose a survey checklist to serve the same core function as surgical checklists-to reduce error. That is, a survey checklist can help medical education practitioners and researchers gather more accurate responses. Designers can use the checklist in the appendix to guide item creation processes or to help evaluate the quality of existing surveys. The checklist focuses on formulating items, crafting response options, and formatting/organizing the whole survey.

    Full Text Available Minority protection is an important, though difficult, issue in company law, and a subtle balance must be struck between the legitimate interests of the majority and minority shareholder(s. The rules on minority protection in the context of the Cross-border Mergers Directive, which was recently adopted and should have been transposed into Member States’ national law towards the end of 2007, are examined in this paper. The authors analyse how minority shareholders are protected within the scope of this Directive and how some of the Member States (such as Germany, Italy, Belgium and the Netherlands have transposed or will transpose some of these protective provisions. The different levels of minority protection (information rights, consultation rights, rights to challenge majority decisions and other specific rights are considered, as well as which types of shareholders can benefit from such protection, and why they should be afforded protection. With respect to the last question, the authors conclude that the change in corporate law encountered especially by the shareholders of the disappearing company seems to be the major rationale underlying the European legislator's decision to introduce minority protection (but not oblige Member States to do so. The authors submit that this reflects too narrow a vision on the need for minority protection because it ignores the fact that the change of the corporate form as a consequence of a merger is in itself sufficient rationale for protecting minority shareholders. It remains somewhat of a mystery as to why the European legislator, while confirming that a cross-border merger should be subject to the same rules as a national merger, has created one possible and very vague exception to that rule.

  19. Conscious Augmentation of Creative State Enhances “Real” Creativity in Open-Ended Analogical Reasoning

    Humans have an impressive ability to augment their creative state (i.e., to consciously try and succeed at thinking more creatively). Though this “thinking cap” phenomenon is commonly experienced, the range of its potential has not been fully explored by creativity research, which has often focused instead on creativity as a trait. A key question concerns the extent to which conscious augmentation of state creativity can improve creative reasoning. Although artistic creativity is also of great interest, it is creative reasoning that frequently leads to innovative advances in science and industry. Here, we studied state creativity in analogical reasoning, a form of relational reasoning that spans the conceptual divide between intelligence and creativity and is a core mechanism for creative innovation. Participants performed a novel Analogy Finding Task paradigm in which they sought valid analogical connections in a matrix of word-pairs. An explicit creativity cue elicited formation of substantially more creative analogical connections (measured via latent semantic analysis). Critically, the increase in creative analogy formation was not due to a generally more liberal criterion for analogy formation (that is, it appeared to reflect “real” creativity rather than divergence at the expense of appropriateness). The use of an online sample provided evidence that state creativity augmentation can be successfully elicited by remote cuing in an online environment. Analysis of an intelligence measure provided preliminary indication that the influential “threshold hypothesis,” which has been proposed to characterize the relationship between intelligence and trait creativity, may be extensible to the new domain of state creativity.

    2015-11-01

    Recently, there has been a trend towards adding a multidisciplinary or multicultural element to traditional monodisciplinary project courses in computing and engineering. In this article, we examine the implications of multidisciplinarity for students' learning experiences during a one-semester project course for real customers. We use a qualitative research approach and base our analysis on students' learning reports on three instances of a project course titled Multidisciplinary working life project. The main contribution of this article is the unified theoretical picture of the learning mechanisms stemming from multidisciplinarity. Our main conclusions are that (1) students generally have a positive view of multidisciplinarity; (2) multidisciplinary teams enable students to better identify their own expertise, which leads to increased occupational identity; and (3) learning experiences are not fixed, as team spirit and student attitude play an important role in how students react to challenging situations arising from introduction of the multidisciplinarity.

    A survey supported by SEMATECH and administered by David Powell Consulting was sent to semiconductor industry leaders to gather information about the mask industry as an objective assessment of its overall condition. The survey was designed with the input of semiconductor company mask technologists and merchant mask suppliers. 2012 marks the 11th consecutive year for the mask industry survey. This year's survey and reporting structure are similar to those of the previous years with minor modifications based on feedback from past years and the need to collect additional data on key topics. Categories include general mask information, mask processing, data and write time, yield and yield loss, delivery times, and maintenance and returns. Within each category are multiple questions that result in a detailed profile of both the business and technical status of the mask industry. Results, initial observations, and key comparisons between the 2011 and 2012 survey responses are shown here, including multiple indications of a shift towards the manufacturing of higher end photomasks.

    Background Cluster randomized trials (CRTs) present unique ethical challenges. In the absence of a uniform standard for their ethical design and conduct, problems such as variability in procedures and requirements by different research ethics committees will persist. We aimed to assess the need for ethics guidelines for CRTs among research ethics chairs internationally, investigate variability in procedures for research ethics review of CRTs within and among countries, and elicit research ethics chairs’ perspectives on specific ethical issues in CRTs, including the identification of research subjects. The proper identification of research subjects is a necessary requirement in the research ethics review process, to help ensure, on the one hand, that subjects are protected from harm and exploitation, and on the other, that reviews of CRTs are completed efficiently. Methods A web-based survey with closed- and open-ended questions was administered to research ethics chairs in Canada, the United States, and the United Kingdom. The survey presented three scenarios of CRTs involving cluster-level, professional-level, and individual-level interventions. For each scenario, a series of questions was posed with respect to the type of review required (full, expedited, or no review) and the identification of research subjects at cluster and individual levels. Results A total of 189 (35%) of 542 chairs responded. Overall, 144 (84%, 95% CI 79 to 90%) agreed or strongly agreed that there is a need for ethics guidelines for CRTs and 158 (92%, 95% CI 88 to 96%) agreed or strongly agreed that research ethics committees could be better informed about distinct ethical issues surrounding CRTs. There was considerable variability among research ethics chairs with respect to the type of review required, as well as the identification of research subjects.

    2005-04-01

    Over the last seven years, a major debate has arisen over whether human cloning should remain legal in the United States. Given that this may be the 'first real global and simultaneous news story on biotechnology' (Einsiedel et al., 2002, p.313), nations around the world have struggled with the implications of this newly viable scientific technology, which is often also referred to as somatic cell nuclear transfer. Since the successful cloning of Dolly the sheep in 1997, and with increasing media attention paid to the likelihood of a successful human reproductive clone coupled with research suggesting the medical potential of therapeutic cloning in humans, members of the scientific community and Christian fundamentalist leaders have become increasingly vocal in the debate over U.S. policy decisions regarding human cloning (Wilmut, 2000). Yet despite a surfeit of public opinion polls and widespread opining in the news media on the topic of human cloning, there have been no empirical studies comparing the views of scientists and Christian fundamentalists in this debate (see Evans, 2002a for a recent study of opinion polls assessing religion and attitudes toward cloning). In order to further investigate the values that underlie scientists' and Christian fundamentalist leader's understanding of human cloning, as well as their differential use of language in communicating about this issue, we conducted an open-ended, exploratory survey of practicing scientists in the field of molecular biology and Christian fundamentalist pastors. We then analyzed the responses from this survey using qualitative discourse analysis. While this was not necessarily a representative sample (in quantitative terms, see Gaskell & Bauer, 2000) of each of the groups and the response rate was limited, this approach was informative in identifying both commonalities between the two groups, such as a focus on ethical concerns about reproductive cloning and the use of scientific terminology, as well

    Full Text Available Abstract Background Millions of child deaths and stillbirths are attributable to birth asphyxia, yet limited information is available to guide policy and practice, particularly at the community level. We surveyed selected policymakers, programme implementers and researchers to compile insights on policies, programmes, and research to reduce asphyxia-related deaths. Method A questionnaire was developed and pretested based on an extensive literature review, then sent by email (or airmail or fax, when necessary to 453 policymakers, programme implementers, and researchers active in child health, particularly at the community level. The survey was available in French and English and employed 5-point scales for respondents to rate effectiveness and feasibility of interventions and indicators. Open-ended questions permitted respondents to furnish additional details based on their experience. Significance testing was carried out using chi-square, F-test and Fisher's exact probability tests as appropriate. Results 173 individuals from 32 countries responded (44%. National newborn survival policies were reported to exist in 20 of 27 (74% developing countries represented, but respondents' answers were occasionally contradictory and revealed uncertainty about policy content, which may hinder policy implementation. Respondents emphasized confusing terminology and a lack of valid measurement indicators at community level as barriers to obtaining accurate data for decision making. Regarding interventions, birth preparedness and essential newborn care were considered both effective and feasible, while resuscitation at community level was considered less feasible. Respondents emphasized health systems strengthening for both supply and demand factors as programme priorities, particularly ensuring wide availability of skilled birth attendants, promotion of birth preparedness, and promotion of essential newborn care. Research priorities included operationalising

    Identifying timely and important research questions using relevant patient-reported outcomes (PROs) in surgery remains paramount in the current medical climate. The inaugural Patient-Reported Outcomes in Surgery (PROS) Conference brought together stakeholders in PROs research in surgery with the aim of creating a research agenda to help determine future directions and advance cross-disciplinary collaboration. To create a research agenda to help determine future directions and advance cross-disciplinary collaboration on the use of PROs in surgery. An iterative web-based interface was used to create a conference-based, modified Delphi survey for registrants at the PROS Conference (January 29-30, 2015), including surgeons, PRO researchers, payers, and other stakeholders. In round 1, research items were generated from qualitative review of responses to open-ended prompts. In round 2, items were ranked using a 5-point Likert scale; attendees were also asked to submit any new items. In round 3, the top 30 items and newly submitted items were redistributed for final ranking using a 3-point Likert scale. The top 20 items by mean rating were selected for the research agenda. An expert-generated research agenda on PROs in surgery. Of the 143 people registered for the conference, 137 provided valid email addresses. There was a wide range of attendees, with the 3 most common groups being plastic surgeons (28 [19.6%]), general surgeons (19 [13.3%]), and researchers (25 [17.5%]). In round 1, participants submitted 459 items, which were reduced through qualitative review to 53 distinct items across 7 themes of PROs research. A research agenda was formulated after 2 successive rounds of ranking. The research agenda identified 3 themes important for future PROs research in surgery: (1) PROs in the decision-making process, (2) integrating PROs into the electronic health record, and (3) measuring quality in surgery with PROs. The PROS Conference research agenda was created using a

    Context Research literacy and the practice of evidence based medicine (EBM) are important initiatives in complementary and alternative medicine (CAM), which requires cultural change within educational institutions for successful implementation. Objective To determine the self-assessed research and EBM perspectives of Chinese medicine Masters degree students at Pacific College of Oriental Medicine, New York campus (PCOM-NY). Design and Methods A survey with seventeen close-ended questions and one open-ended question was administered through Survey Monkey to students at PCOM-NY. Results The survey was sent to 420 Masters students and 176 (41.9%) responded. Students in all 4 years of the Masters degree indicated a generally high degree interest in, and support for the value of research. However increasing years (1 – 4) in the program was associated with lower interest post-graduation in research participation and entering the doctoral program, and 4th year students reported low levels of interest in having greater research content and training in their Masters degree programs. Students who responded to the open-ended question (23% of respondents) expressed enthusiasm for research and concerns about the relevance of research to Chinese medicine. Conclusions Consistent with findings in similar studies at CAM colleges, interest in research and EBM of the PCOM-NY Masters students appeared to decline with increasing years in the program. Concerns around paradigm and epistemological issues associated with research and EBM among Chinese medicine students and practitioners warrants further investigation, and may be an important challenge for integrative medicine.

    Research literacy and the practice of evidence-based medicine (EBM) are important initiatives in complementary and alternative medicine (CAM), which requires cultural change within educational institutions for successful implementation. To determine the self-assessed research and EBM perspectives of Chinese medicine Masters degree students at Pacific College of Oriental Medicine, New York campus (PCOM-NY). A survey with 17 close-ended questions and one open-ended question was administered through Survey Monkey to students at PCOM-NY. The survey was sent to 420 Masters students and 176 (41.9%) responded. Students in all four years of the Masters degree indicated a generally high degree of interest in, and support for the value of research. However, increasing years (one to four years) in the program was associated with lower interest in post-graduation research participation and entering the doctoral program, and the fourth year students reported low levels of interest in having greater research content and training in their Masters degree programs. Students who responded to the open-ended question (23% of respondents) expressed enthusiasm for research and concerns about the relevance of research in Chinese medicine. Consistent with findings in similar studies at CAM colleges, interest in research, and EBM of the PCOM-NY Masters students appeared to decline with increasing years in the program. Concerns around paradigm and epistemological issues associated with research and EBM among Chinese medicine students and practitioners warrants further investigation, and may be an important challenge for integrative medicine.

    Recent surveys suggest few emergency medicine (EM) training programs have formal evidence-based medicine (EBM) or journal club curricula. Our primary objective was to describe the methods of EBM training in Royal College of Physicians and Surgeons of Canada (RCPSC) EM residencies. Secondary objectives were to explore attitudes regarding current educational practices including e-learning, investigate barriers to journal club and EBM education, and assess the desire for national collaboration. A 16-question survey containing binary, open-ended, and 5-pt Likert scale questions was distributed to the 14 RCPSC-EM program directors. Proportions of respondents (%), median, and IQR are reported. The response rate was 93% (13/14). Most programs (85%) had established EBM curricula. Curricula content was delivered most frequently via journal club, with 62% of programs having 10 or more sessions annually. Less than half of journal clubs (46%) were led consistently by EBM experts. Four programs did not use a critical appraisal tool in their sessions (31%). Additional teaching formats included didactic and small group sessions, self-directed e-learning, EBM workshops, and library tutorials. 54% of programs operated educational websites with EBM resources. Program directors attributed highest importance to two core goals in EBM training curricula: critical appraisal of medical literature, and application of literature to patient care (85% rating 5 - "most importance", respectively). Podcasts, blogs, and online journal clubs were valued for EBM teaching roles including creating exposure to literature (4, IQR 1.5) and linking literature to clinical practice experience (4, IQR 1.5) (1-no merit, 5-strong merit). Five of thirteen respondents rated lack of expert leadership and trained faculty educators as potential limitations to EBM education. The majority of respondents supported the creation of a national unified EBM educational resource (4, IQR 1) (1-no support, 5- strongly

    Full Text Available Occupation is key in socioeconomic research. As in other survey modes, most web surveys use an open-ended question for occupation, though the absence of interviewers elicits unidentifiable or aggregated responses. Unlike other modes, web surveys can use a search tree with an occupation database. They are hardly ever used, but this may change due to technical advancements. This article evaluates a three-step search tree with 1,700 occupational titles, used in the 2010 multilingual WageIndicator web survey for UK, Belgium and Netherlands (22,990 observations. Dropout rates are high; in Step 1 due to unemployed respondents judging the question not to be adequate, and in Step 3 due to search tree item length. Median response times are substantial due to search tree item length, dropout in the next step and invalid occupations ticked. Overall the validity of the occupation data is rather good, 1.7-7.5% of the respondents completing the search tree have ticked an invalid occupation.

    2015-08-25

    The Worker Safety and Security Team (WSST) at Los Alamos National Laboratory holds an annual festival, WSST-fest, to engage workers and inform them about safety- and securityrelated matters. As part of the 2015 WSST-fest, workers were given the opportunity to participate in a survey assessing their engagement in their organizations and work environments. A total of 789 workers participated in the 23-question survey where they were also invited, optionally, to identify themselves, their organization, and to give open-ended feedback. The survey consisted of 23 positive statements (i.e. “My organization is a good place to work.”) with which the respondent could express a level of agreement. The text of these statements are provided in Table 1. The level of agreement corresponds to a 5-level Likert scale ranging from “Strongly Disagree” to “Strongly Agree.” In addition to assessing the overall positivity or negativity of the scores, the results were partitioned into several cohorts based on the response meta-data (self-identification, comments, etc.) to explore trends. Survey respondents were presented with the options to identify themselves, their organizations and to provide comments. These options suggested the following questions about the data set.

    Mixing survey administration modes has generated concern about the comparability of responses between modes. To explore the differences in respondent profiles, and responses between Internet and telephone questionnaires in a survey on respiratory diseases. The data were generated from a mixed Internet and telephone survey of respiratory diseases among children in Montreal (Quebec), in 2006. Comparison of 12 selected questions was performed after standardization for respondent education and income. Stratification of analysis on education and income categories was also performed for the questions with significantly divergent responses. Six questions showed significant differences in responses between modes after standardization. The largest differences among the closed-ended questions were observed for highly prevalent symptoms, dry cough during the night (difference of 9% for positive answer [PInternet and telephone responses to selected questions were not completely explained by socioeconomic disparities among the respondents. In a mixed-mode survey (Internet and telephone), caution should be used when formulating sensitive, complex, open-ended and long-ended questions, and those related to highly prevalent and nonspecific symptoms.

    2013-09-01

    A comprehensive survey was sent to merchant and captive mask shops to gather information about the mask industry as an objective assessment of its overall condition. 2013 marks the 12th consecutive year for this process. Historical topics including general mask profile, mask processing, data and write time, yield and yield loss, delivery times, maintenance, and returns were included and new topics were added. Within each category are multiple questions that result in a detailed profile of both the business and technical status of the mask industry. While each year's survey includes minor updates based on feedback from past years and the need to collect additional data on key topics, the bulk of the survey and reporting structure have remained relatively constant. A series of improvements is being phased in beginning in 2013 to add value to a wider audience, while at the same time retaining the historical content required for trend analyses of the traditional metrics. Additions in 2013 include topics such as top challenges, future concerns, and additional details in key aspects of mask masking, such as the number of masks per mask set per ground rule, minimum mask resolution shipped, and yield by ground rule. These expansions beyond the historical topics are aimed at identifying common issues, gaps, and needs. They will also provide a better understanding of real-life mask requirements and capabilities for comparison to the International Technology Roadmap for Semiconductors (ITRS).

    Full Text Available Background: A handful of medical schools in the U.S. are awarding medical degrees after three years. While the number of three-year pathway programs is slowly increasing there is little data on the opinions of medical education leaders on the need for shortening training. Purpose: To survey deans and program directors (PDs to understand the current status of 3-year medical degree programs and to elicit perceptions of the need for shortening medical school and the benefits and liabilities of 3-year pathway programs (3YPP. Methods: Online surveys were emailed to the academic deans of all U.S. medical schools and to a convenience sample of residency and fellowship PDs. Frequency distributions are reported for key survey items and content analysis was used to describe open-ended responses. Results: Of the respondents, 7% have a 3YPP, 4% were developing one, and 35% were considering development. In 2014, 47% of educational deans and 32% of PDs agreed that there may be a need to shorten medical school. From a list of benefits, both deans and PDs agreed that the greatest benefit to a 3YPP was debt reduction (68%. PDs and deans felt reduced readiness for independence, reduced exposure to complementary curricula regarding safety and quality improvement, premature commitment to a specialty, and burnout were all potential liabilities. From a list of concerns, PDs were concerned about depth of clinical exposure, direct patient care experience, ability to assume increased responsibility, level of maturity, and certainty regarding career choice. Conclusions: Over one-third of medical schools are considering the development of a 3YPP. While there may be benefits for a select group of students, concerns regarding maturity, depth of clinical exposure, and competency must be addressed for these programs to be well received.

    2016-05-26

    The European-study on Quantifying Utility of Investment in Protection from Tobacco (EQUIPT) project aimed to study transferability of economic evidence by co-creating the Tobacco Return On Investment (ROI) tool, previously developed in the United Kingdom, for four sample countries (Germany, Hungary, Spain and the Netherlands). The EQUIPT tool provides policymakers and stakeholders with customized information about the economic and wider returns on the investment in evidence-based tobacco control, including smoking cessation interventions. A Stakeholder Interview Survey was developed to engage with the stakeholders in early phases of the development and country adaptation of the ROI tool. The survey assessed stakeholders' information needs, awareness about underlying principles used in economic analyses, opinion about the importance, effectiveness and cost-effectiveness of tobacco control interventions, and willingness to use a Health Technology Assessment (HTA) tool such as the ROI tool. A cross sectional study using a mixed method approach was conducted among participating stakeholders in the sample countries and the United Kingdom. The individual questionnaire contained open-ended questions as well as single choice and 7- or 3-point Likert-scale questions. The results corresponding to the priority and needs assessment and to the awareness of stakeholders about underlying principles used in economic analysis are analysed by country and stakeholder categories. Stakeholders considered it important that the decisions on the investments in tobacco control interventions should be supported by scientific evidence, including prevalence of smoking, cost of smoking, quality of life, mortality due to smoking, and effectiveness, cost-effectiveness and budget impact of smoking cessation interventions. The proposed ROI tool was required to provide this granularity of information. The majority of the stakeholders were aware of the general principles of economic analyses used in

    2009-08-01

    This report describes the survey operation, survey and processing methods and the deliverables of an aerogeophysical survey in Olkiluoto area in May 2009. The survey was conducted by Geological Survey of Finland (GTK). The survey aircraft was a twin-engine Twin Otter operated by Finnish Aviation Academy (SIO) and owned by Natural Environment Research Council / British Geological Survey (NERC / BGS), with whom GTK has established a joint venture called Joint Airborne-geoscience Capability (JAC). The survey was conducted in May 2009 between May 5th and May 18th. The survey consists of ten separate survey flights and two magnetic calibration flights. The survey was based in Pori airport. Survey line spacing was 50 meters and nominal survey altitude was 30 meters. Measurements were completed in May 2009, and data processing and reporting was done in June 2009. Two cesium magnetometers installed onboard the aircraft (at the left wingtip and in a nose cone) were measuring the magnetic total field intensity during the survey flights. An automatic compensation unit corrected the aircraft attitude errors in the magnetic data in real time. The four-frequency electromagnetic (EM) unit included four transmitter coils with amplifiers in right wingtip and four receiver coils in left wingtip. Frequencies were 900 Hz, 3 kHz, 14 kHz and 24.5 kHz. The gamma spectrometer with two crystal packages (total volume 42 litres) measured the 256 channel energy spectra. In addition, auxiliary parameters such as flight altitude and aircraft attitude were also recorded simultaneously. Reference ground base station was used for recording the temporal variations in the magnetic field and also reference data for post-positioning of coordinate information. In the post-processing phase, heading correction, base station correction and microlevelling procedures were applied to the magnetic data. The EM data and radiometric data were corrected with calibration coefficients and levelled. The data was

  2. Survey of Hatching Spines of Bee Larvae Including Those of Apis mellifera (Hymenoptera: Apoidea).

    Rozen, Jerome G; Shepard Smith, Corey; Cane, James H

    2017-07-01

    This article explores the occurrence of hatching spines among bee taxa and how these structures enable a larva on hatching to extricate itself from the egg chorion. These spines, arranged in a linear sequence along the sides of the first instar just dorsal to the spiracles, have been observed and recorded in certain groups of solitary and cleptoparasitic bee taxa. After eclosion, the first instar remains loosely covered by the egg chorion. The fact that this form of eclosion has been detected in five families (Table 1 identifies four of the families. The fifth family is the Andrenidae for which the presence of hatching spines in the Oxaeinae will soon be announced.) of bees invites speculation as to whether it is a fundamental characteristic of bees, or at least of solitary and some cleptoparasitic bees. The wide occurrence of these spines has prompted the authors to explore and discover their presence in the highly eusocial Apis mellifera L. Hatching spines were indeed discovered on first instar A. mellifera. The honey bee hatching process appears to differ in that the spines are displayed somewhat differently though still along the sides of the body, and the chorion, instead of splitting along the sides of the elongate egg, seems to quickly disintegrate from the emerging first instar in association with the nearly simultaneous removal of the serosa that covers and separates the first instar from the chorion. Unexpected observations of spherical bodies of various sizes perhaps containing dissolving enzymes being discharged from spiracular openings during hatching may shed future light on the process of how A. mellifera effects chorion removal during eclosion. Whereas hatching spines occur among many groups of bees, they appear to be entirely absent in the Nomadinae and parasitic Apinae, an indication of a different eclosion process. © The Authors 2017.

    The paper contains a brief description of selected investigations carried out in the south Baltic coastal zone, with the particular focus on the history and recent activities conducted at the Coastal Research Station in Lubiatowo (CRS Lubiatowo), Poland. These activities comprise field investigations of nearshore hydrodynamic, lithodynamic, and morphodynamic processes. The study area is a sandy multi-bar shore with a mild slope, much exposed to the impact of waves approaching from NW-NE sector. The shore has a dissipative character which means that the wave energy is subject to gradual dissipation in the nearshore zone and only a small part of this energy is reflected by the shore. Due to the big wind fetch in N-NNE direction, the location of CRS Lubiatowo is favourable to registration of the maximum values of parameters of hydrodynamic and morphodynamic processes which occur in the Baltic during extreme storms.

    The authors conducted a survey examining (1) the current state of evidence-based medicine (EBM) curricula in US and Canadian medical schools and corresponding learning objectives, (2) medical educators' and librarians' participation in EBM training, and (3) barriers to EBM training. A survey instrument with thirty-four closed and open-ended questions was sent to curricular deans at US and Canadian medical schools. The survey sought information on enrollment and class size; EBM learning objectives, curricular activities, and assessment approaches by year of training; EBM faculty; EBM tools; barriers to implementing EBM curricula and possible ways to overcome them; and innovative approaches to EBM education. Both qualitative and quantitative methods were used for data analysis. Measurable learning objectives were categorized using Bloom's taxonomy. One hundred fifteen medical schools (77.2%) responded. Over half (53%) of the 900 reported learning objectives were measurable. Knowledge application was the predominant category from Bloom's categories. Most schools integrated EBM into other curricular activities; activities and formal assessment decreased significantly with advanced training. EBM faculty consisted primarily of clinicians, followed by basic scientists and librarians. Various EBM tools were used, with PubMed and the Cochrane database most frequently cited. Lack of time in curricula was rated the most significant barrier. National agreement on required EBM competencies was an extremely helpful factor. Few schools shared innovative approaches. Schools need help in overcoming barriers related to EBM curriculum development, implementation, and assessment. Findings can provide a starting point for discussion to develop a standardized competency framework.

The study design consisted of a written survey focusing on eight dimensions relating to practice: Interpersonal Skills, Confidence/Coping Skills, Professional Networks, Professional Practice Management, Professional Patient Management, Prevention, Holistic Care, and Self-Directed Learning. Part 1 of the survey required participants to choose from six possible responses on how well they believe their CM course has prepared them in relation to 41 statements about aspects of practice (1 = very inadequately through to 6 = very adequately). Part 2 consisted of nine open-ended questions. The study participants were final-year Bachelor degree CM and acupuncture students from Australian universities and privately operated educational institutions. ANALYSIS AND MAIN OUTCOME MEASURES: Part 1 of survey: mean scores on the eight dimensions of practice. Part 2 of survey: transcribed responses were imported into NVivo8. Each part of the questions was analyzed and grouped into broad themes. Seventy-one (71) of one hundred and seven (71/107) invited students (average age 29.4 years +/- 7.4 years) participated in the survey conducted in 2008. Mean scores on eight dimensions of clinical practice were as follows: Interpersonal Skills 3.9 (+/-1.1), Confidence/Coping Skills 4.0 (+/-0.8), Professional Networks 4.2 (+/-0.8), Professional Practice Management 4.2 (+/-0.8), Professional Patient Management 4.7 (+/-0.7), Prevention 4.6 (+/-0.7), Holistic Care 4.4 (+/-0.7), and Self-Directed Learning 4.6 (+/-0.6). There was no significant difference in mean scores across gender. Responses to Part 2 indicated a range of suggestions on the strengths of educational courses and how transition to clinical practice could be facilitated. In general, CM

    In Kenya, abortion is illegal under most circumstances, yet about 48 abortions per 1,000 women occurred in 2012. Given the stigma around abortion, little is known about the availability of safe abortion. Thus, we explored the feasibility and acceptability of using SMS mobile surveys to collect information about women's pregnancy and abortion histories in Kenya. We sent a one-time mobile survey to 500 18-24year old women who had opted-in to a 16,000-person mobile survey panel. Women elected to answer questions about pregnancy only (number of pregnancies, number of births, age at first pregnancy) or pregnancy and abortion (ever tried to obtain an abortion and whether medical treatment was sought for any complications). The final question for all survey versions was an open-ended question asking respondents how they felt answering these questions. 356 (71%) responded to the initial survey question and 333 (94%) consented to answer questions about pregnancy. Of these, 233 (70%) agreed to answer questions about just pregnancy and 76 (23%) agreed to answer questions about pregnancy and abortion. Three-quarters of respondents indicated that they had positive or neutral feelings about answering these questions over SMS. Lastly, all data was retrieved within 24h of survey distribution allowing for immediate analysis and dissemination. Women's willingness to share their pregnancy history suggests mobile surveys are a cost-effective and accessible method for gathering information on abortion in Kenya. Copyright © 2017 Elsevier B.V.

    2012-01-01

    A survey programme was initiated several years ago with the aim of estimating the incidence of naturally occurring radioactive material (NORM) exposure for workers in the oil and gas industry, gold mining, spas, and a tourist cavern in Argentina. This work presents the procedures, methods employed, and results to date from the survey, including protection and remedial actions recommended when deemed necessary. Radium isotope concentrations measured in some samples were well above the exemption values established by IAEA Standards. Elevated radon levels (above the action level established for workplaces) were detected in the gas facilities, the gold mine, and the tourist cavern. The pertinent authorities and the facilities were informed of the detected values in order to take actions to reduce concentrations. In terms of the spas, almost all values for geothermal waters were below the corresponding guidance levels. Some regulatory aspects for the management of NORM are suggested.

    To provide international consensus on the competencies required by healthcare professionals in order to provide specialist care for teenagers and young adults (TYA) with cancer. Modified e-Delphi survey. International, multicentre study. Experts were defined as professionals having worked in TYA cancer care for more than 12 months. They were identified through publications and professional organisations. Round 1, developed from a previous qualitative study, included 87 closed-ended questions with responses on a nine-point Likert scale and further open-ended responses to identify other skills, knowledge and attitudes. Round 2 contained only items with no consensus in round 1 and suggestions of additional items of competency. Consensus was defined as a median score ranging from 7 to 9 and strength of agreement using mean absolute deviation of the median. A total of 179 registered to be members of the expert panel; valid responses were available from 158 (88%) in round 1 and 136/158 (86%) in round 2. The majority of participants were nurses (35%) or doctors (39%) from Europe (55%) or North America (35%). All 87 items in round 1 reached consensus with an additional 15 items identified for round 2, which also reached consensus. The strength of agreement was mostly high for statements. The areas of competence rated most important were agreed to be: 'Identify the impact of disease on young people's life' (skill), 'Know about side effects of treatment and how this might be different to those experienced by children or older adults' (knowledge), 'Honesty' (attitude) and 'Listen to young people's concerns' (aspect of communication). Given the high degree of consensus, this list of competencies should influence education curriculum, professional development and inform workforce planning. Variation in strength of agreement for some competencies between professional groups should be explored further in pursuit of effective multidisciplinary team working. Published by the BMJ

    Dietitians are engaging with mobile health (mHealth) technologies, particularly with diet and nutrition apps in their patient care. Despite the plethora of apps available, the majority are not designed with a dietitian's input. The aim of this study was to identify the user preferences of dietitians in relation to tools, resources, and design features for smartphone health apps that would support their dietetic professional practice and their patients. As part of a larger international Web-based survey of health-app use among dietitians, three open-ended responses were included for specific exploration of app design features and additional resources or tools that could guide the development of apps for use in dietetic practice and patient care. Inductive thematic analysis of responses was conducted using the qualitative data analysis program, NVivo version 11 (QSR International Pty Ltd), to understand the design preferences and features valued by dietitians. The responses from 381 dietitian respondents were analyzed. Five key themes were identified. Dietitians wanted access to credible apps, suggesting that dietetic associations should have greater involvement in reviewing and endorsing evidence-based apps for use in dietary counseling. Improvements to the usability of apps, relating to their ease of use and design, were also raised, as self-monitoring of dietary behaviors using existing nutrition apps was deemed to be burdensome. Furthermore, apps providing dietitian-oriented support were favored, for example, those with the ability to streamline the dietary assessment process, so that dietitians could spend more time on dietary counseling and negotiating patient goals for dietary and lifestyle behavior change. Provision of patient-oriented support, such as functionality to tailor apps to patient-specific needs, was also considered important. Finally, respondents valued apps that could integrate into their work systems to enhance the quality of the dietitian

    ) experience with methods of protein purification; (iii) incorporation of appropriate controls into experiments; (iv) use of basic statistics in data analysis; (v) writing papers and grant proposals in accepted scientific style; (vi) peer review; (vii) oral presentation of results and proposals; and (viii) introduction to molecular modeling. Figure 1 illustrates the modular nature of the lab curriculum. Elements from each of the exercises can be separated and treated as stand-alone exercises, or combined into short or long projects. We have been able to offer the opportunity to use sophisticated molecular modeling in the final module through funding from an NSF-ILI grant. However, many of the benefits of the research proposal can be achieved with other computer programs, or even by literature survey alone. Figure 1.Design of project-based biochemistry laboratory. Modules (projects, or portions of projects) are indicated as boxes. Each of these can be treated independently, or used as part of a larger project. Solid lines indicate some suggested paths from one module to the next. The skills and knowledge required for protein purification and design are developed in three units: (i) an introduction to critical assays needed to monitor degree of purification, including an evaluation of assay parameters; (ii) partial purification by ion-exchange techniques; and (iii) preparation of a grant proposal on protein design by mutagenesis. Brief descriptions of each of these units follow, with experimental details of each project at the end of this paper. Assays for Lysozyme Activity and Protein Concentration (4 weeks) The assays mastered during the first unit are a necessary tool for determining the purity of the enzyme during the second unit on purification by ion exchange. These assays allow an introduction to the concept of specific activity (units of enzyme activity per milligram of total protein) as a measure of purity. In this first sequence, students learn a turbidimetric assay

    We present the first results of the SOAR Gravitational Arc Survey (SOGRAS). The survey imaged 47 clusters in two redshift intervals centered at z=0.27 and z=0.55, targeting the richest clusters in each interval. Images were obtained in the g', r' and i' bands with a median seeing of 0.83, 0.76 and 0.71 arcsec, respectively, in these filters. Most of the survey clusters are located within the Sloan Digital Sky Survey (SDSS) Stripe-82 region and all of them are in the SDSS footprint. We present the first results of the survey, including the 6 best strong lensing systems, photometric and morphometric catalogs of the galaxy sample, and cross matches of the clusters and galaxies with complementary samples (spectroscopic redshifts, photometry in several bands, X-ray and Sunyaev Zel'dovich clusters, etc.), exploiting the synergy with other surveys in Stripe-82. We apply several methods to characterize the gravitational arc candidates, including the Mediatrix method (Bom et al. 2012) and ArcFitting (Furlanetto et al. 2012), and for the subtraction of galaxy cluster light. Finally, we apply strong lensing inversion techniques to the best systems, providing constraints on their mass distribution. The analyses of a spectral follow-up with Gemini and the derived dynamical masses are presented in a poster submitted to this same meeting (Cibirka et al.). Deeper follow-up images with Gemini strengthen the case for the strong lensing nature of the candidates found in this survey.

    Project management is a critical skill for nurse informaticists who are in prominent roles developing and implementing clinical information systems. It should be included in the nursing informatics curriculum, as evidenced by its inclusion in informatics competencies and surveys of important skills for informaticists. The University of Pennsylvania School of Nursing includes project management in two of the four courses in the master's level informatics minor. Course content includes the phases of the project management process; the iterative unified process methodology; and related systems analysis and project management skills. During the introductory course, students learn about the project plan, requirements development, project feasibility, and executive summary documents. In the capstone course, students apply the system development life cycle and project management skills during precepted informatics projects. During this in situ experience, students learn, the preceptors benefit, and the institution better prepares its students for the real world.

    Exoskeleton technology has potential benefits for wheelchair users' health and mobility. However, there are practical barriers to their everyday use as a mobility device. To further understand potential exoskeleton use, and facilitate the development of new technologies, a study was undertaken to explore perspectives of wheelchair users and healthcare professionals on reasons for use of exoskeleton technology, and the importance of a variety of device characteristics. An online survey with quantitative and qualitative components was conducted with wheelchair users and healthcare professionals working directly with individuals with mobility impairments. Respondents rated whether they would use or recommend an exoskeleton for four potential reasons. Seventeen design features were rated and compared in terms of their importance. An exploratory factor analysis was conducted to categorize the 17 design features into meaningful groupings. Content analysis was used to identify themes for the open ended questions regarding reasons for use of an exoskeleton. 481 survey responses were analyzed, 354 from wheelchair users and 127 from healthcare professionals. The most highly rated reason for potential use or recommendation of an exoskeleton was health benefits. Of the design features, 4 had a median rating of very important: minimization of falls risk, comfort, putting on/taking off the device, and purchase cost. Factor analysis identified two main categories of design features: Functional Activities and Technology Characteristics. Qualitative findings indicated that health and physical benefits, use for activity and access reasons, and psychosocial benefits were important considerations in whether to use or recommend an exoskeleton. This study emphasizes the importance of developing future exoskeletons that are comfortable, affordable, minimize fall risk, and enable functional activities. Findings from this study can be utilized to inform the priorities for future

    The Southern H ii Region Discovery Survey is a survey of the third and fourth quadrants of the Galactic plane that will detect radio recombination line (RRL) and continuum emission at cm-wavelengths from several hundred H ii region candidates using the Australia Telescope Compact Array. The targets for this survey come from the WISE Catalog of Galactic H ii Regions and were identified based on mid-infrared and radio continuum emission. In this pilot project, two different configurations of the Compact Array Broad Band receiver and spectrometer system were used for short test observations. The pilot surveys detected RRL emission from 36 of 53 H ii region candidates, as well as seven known H ii regions that were included for calibration. These 36 recombination line detections confirm that the candidates are true H ii regions and allow us to estimate their distances.

    The Parenteral Drug Association conducted an anonymous global survey of quality culture in the pharmaceutical industry to determine whether there is a relationship between certain quality behaviors and certain quality attributes, and whether these quality attributes could be used as surrogates (or proxy variables) to assess quality culture. Other studies have shown that an unhealthy quality culture is a root cause of many quality or compliance issues seen by sites and organizations. Statistical analysis of survey data suggests that certain attributes are driving good behaviors, and the demographic data suggests that this relationship holds irrespective of the geographic location of the site. Executive survey respondents had a more optimistic view of the current state of quality culture than survey respondents at large, with cross-functional vision showing the biggest gap (P-value = 0.07, F-Test). The top five quality attributes that can serve as surrogates for quality culture were (1) Management communication that quality is everyone's responsibility, (2) Site has formal quality improvement objectives and targets, (3) Clear performance criteria for feedback and coaching, (4) Quality topics included in at least half of all-hands meetings, and (5) Collecting error prevention metrics. These identified mature quality attributes are related to management responsibility, and continual improvement of the pharmaceutical quality system sections of ICH Q10, and therefore may be amenable to be incorporated in audit programs or in regulatory inspections. Additional research and discussion is required to build a coherent approach, which the pharmaceutical industry and regulators can adopt. © PDA, Inc. 2015.
