    Full Text Available Space weather effects can strongly influence high-frequency (HF communications by changing the ionospheric environment through which the radio waves propagate. Since many systems utilize HF communications, the ability to make real-time assessments of propagation conditions is an important part of space weather monitoring systems. In this paper, we present new techniques for measuring high-latitude HF communications link parameters using data from SuperDARN radars. These techniques use ground-scatter returns to define the variation in skip distance with frequency. From these data, the maximum usable frequency (MUF as a function of range is determined and ionospheric critical frequencies are estimated. These calculations are made in near-real-time and the results are made available on the World Wide Web. F-region critical frequencies calculated using this method show good agreement with ionosonde data.Key words.

    Communication among physicians, staff, and patients is a critical element in patient safety. Effective communication skills can be taught and improved through training and awareness. The practice of family medicine allows for long-term relationships with patients, which affords opportunities for ongoing, high-quality communication. There are many barriers to effective communication, including patient factors, clinician factors, and system factors, but tools and strategies exist to address these barriers, improve communication, and engage patients in their care. Use of universal precautions for health literacy, appropriate medical interpreters, and shared decision-making are evidence-based tools that improve communication and increase patient safety.

    The 2015 Institute of Medicine report on diagnostic error has placed a national spotlight on the importance of improving communication among clinicians and between clinicians and patients [1]. The report emphasizes the critical role that communication plays in patient safety and outlines ways that pathologists can support this process. Despite recognition of communication as an essential element in patient care, pathologists currently undergo limited (if any) formal training in communication skills. To address this gap, we at the University of Washington Medical Center developed communication training with the goal of establishing best practice procedures for effective pathology communication. The course includes lectures, role playing, and simulated clinician-pathologist interactions for training and evaluation of pathology communication performance. Providing communication training can help create reliable communication pathways that anticipate and address potential barriers and errors before they happen. © 2016 American Medical Association.

    TeenSmart International harnesses the power and flexibility of technology to empower youth to take personal responsibility for their health and lifestyle choices. Access to the Internet via mobile phones is often cheaper than paying to connect to a wired broadband service, and in rural areas, mobile networks may be the only means of accessing the Internet. This study assessed the feasibility, acceptability, and impact of "cues to action" or brief motivating cell phone text messages to improve adolescent family communication and relationships. A quasi-experimental design using a voluntary sample of 100 Nicaraguan youth at high risk for poor family communication participated. Pre- and posttest quantitative measures using Student t statistical analysis, a focus group, and a participant testimony provided the evaluation evidence. Findings suggest that there are economic and motivational barriers to the use of text messages, but when barriers are eliminated, the behavioral results are positive. Youth who received two weekly text messages over a 6-month period demonstrated statistically significant improvements in family communication perceptions, attitudes, and behaviors, strengthening their family communications and relationships. Brief and personalized text messaging "cues to action" may be a cost-effective intervention to improve adolescent healthy lifestyle behaviors.

  10. Clinical trials update from the Heart Failure Society of America Meeting 2009: FAST, IMPROVE-HF, COACH galectin-3 substudy, HF-ACTION nuclear substudy, DAD-HF, and MARVEL-1.

    This article presents findings and a commentary on late-breaking trials presented during the meeting of the Heart Failure Society of America in September 2009. Unpublished reports should be considered as preliminary, since analyses may change in the final publication. The FAST trial showed somewhat better performance of intrathoracic impedance for prediction of deterioration in patients with heart failure (HF) when compared with daily weighing. The IMPROVE-HF study reported the benefits of education on the management of patients with systolic HF. Galectin-3 appeared a useful method for improving risk stratification of patients with chronic HF in a substudy of the COACH trial. A nuclear substudy of the HF-ACTION trial failed to demonstrate that resting myocardial perfusion imaging, a measure of myocardial scar and viability, was clinically useful. A small randomized controlled trial (DAD-HF) suggested that the use of low-dose dopamine in patients with acutely decompensated HF was associated with less deterioration in renal function and less hypokalaemia. The MARVEL-1 trial raises further concerns about the safety of myoblast transplantation in ischaemic HF.

  11. Conduction Mechanism and Improved Endurance in HfO2-Based RRAM with Nitridation Treatment

    A nitridation treatment technology with a urea/ammonia complex nitrogen source improved resistive switching property in HfO2-based resistive random access memory (RRAM). The nitridation treatment produced a high performance and reliable device which results in superior endurance (more than 109 cycles) and a self-compliance effect. Thus, the current conduction mechanism changed due to defect passivation by nitrogen atoms in the HfO2 thin film. At a high resistance state (HRS), it transferred to Schottky emission from Poole-Frenkel in HfO2-based RRAM. At low resistance state (LRS), the current conduction mechanism was space charge limited current (SCLC) after the nitridation treatment, which suggests that the nitrogen atoms form Hf-N-Ox vacancy clusters (Vo +) which limit electron movement through the switching layer.

    In this paper, we investigate an Al 2 O 3 /HfSiO stack as the blocking layer of a metal—oxide—nitride—oxide—silicon-type (MONOS) memory capacitor. Compared with a memory capacitor with a single HfSiO layer as the blocking layer or an Al 2 O 3 /HfO 2 stack as the blocking layer, the sample with the Al 2 O 3 /HfSiO stack as the blocking layer shows high program/erase (P/E) speed and good data retention characteristics. These improved performances can be explained by energy band engineering. The experimental results demonstrate that the memory device with an Al 2 O 3 /HfSiO stack as the blocking layer has great potential for further high-performance nonvolatile memory applications.

  14. Improved method for Hf separation from silicate rocks for isotopic analysis using Ln-spec resin column

    International Nuclear Information System (INIS)

    Shinjo, Ryuichi; Ginoza, Yuko; Meshesha, Daniel

    2010-01-01

    An improved chemical separation method for Hf isotope ratio measurement using both the thermal ionization mass spectrometer (TIMS) and the multiple collector-inductively coupled plasma-mass spectrometer (MC-ICP-MS) is presented in this paper. In the first column (2.5-ml Eichrom Ln-spec resin), Hf cut was collected with 2M HCl-0.2M HF after washing the major elements, HREE, Ti, Nb, and Zr. For further Hf purification, the second column (1-ml Ln-spec resin) chemistry was conducted in a manner similar to that of the first column. The first column is designed for treatment with a 0.5-g silicate rock sample for TIMS analysis. Thus, because the Hf amount required for MC-ICP-MS analysis is much lesser than that required for TIMS analysis, the column chemistry for MC-ICP-MS analysis can be scaled down, depending on the amount of digested sample. Although there is a need to improve the TIMS technique, the TIMS Hf data obtained for geological reference rocks and Ethiopian flood basalts after the application of the proposed separation methods are consistent, within analytical error, with the previously reported data obtained using the MC-ICP-MS. The advantages of the proposed method include a reduction in the amount of reagents used (hence, a consequent reduction in the blank contribution), reduction in the time required, and a simplified preparation requiring a fewer number of acids.

    ENGLISH ABSTRACT: Communication between manufacturing robots and autonomous vehicles in the industrial environment is important, sinceinstructions and information are crucial for communication between the control station and the robot station. Information is required between different manufacturing robots for optimal performance and dedication to industrial tasks within the environment. Failures in communication could cause robots to be a safety hazard or to perform tasks that are not required. This article shows how communication was improved with the use of the Robotics Communication Protocol (RCP and an extension of this protocol.

  16. Analysis of the Effect of Electron Density Perturbations Generated by Gravity Waves on HF Communication Links

    2017-12-01

    In the present work, ray tracing of high frequency (HF) signals in ionospheric disturbed conditions is analyzed, particularly in the presence of electron density perturbations generated by gravity waves (GWs). The three-dimensional numerical ray tracing code by Jones and Stephenson, based on Hamilton's equations, which is commonly used to study radio propagation through the ionosphere, is used. An electron density perturbation model is implemented to this code based upon the consideration of atmospheric GWs generated at a height of 150 km in the thermosphere and propagating up into the ionosphere. The motion of the neutral gas at these altitudes induces disturbances in the background plasma which affects HF signals propagation. To obtain a realistic model of GWs in order to analyze the propagation and dispersion characteristics, a GW ray tracing method with kinematic viscosity and thermal diffusivity was applied. The IRI-2012, HWM14 and NRLMSISE-00 models were incorporated to assess electron density, wind velocities, neutral temperature and total mass density needed for the ray tracing codes. Preliminary results of gravity wave effects on ground range and reflection height are presented for low-mid latitude ionosphere.

    Oxide dispersed (OD) {beta}-NiAl coatings and OD-free {beta}-NiAl coatings were deposited onto a Hf-containing Ni-based superalloy by electron beam physical vapor deposition (EB-PVD). Excessive enrichment of Hf was found in the TGO on the OD-free coating due to outward diffusion of Hf from the superalloy, causing accelerated TGO thickening and spalling. The OD-coating effectively prevented Hf from outward diffusion. Only small amount of Hf diffused to the coating surface and improved the TGO adherence by virtue of the reactive element effect. The OD-coating exhibited an improved oxidation resistance as compared to the OD-free coating.

    Nursing communication has become more important than ever before because quality of nursing services largely depends on the quality of communication in a very competitive health care environment. This article was to introduce ways to improve nursing communication using conversation analysis. This was a review study on conversation analysis, critically examining previous studies in nursing communication and interpersonal relationships. This study provided theoretical backgrounds and basic assumptions of conversation analysis which was influenced by ethnomethodology, phenomenology, and sociolinguistic. In addition, the characteristics and analysis methods of conversation analysis were illustrated in detail. Lastly, how conversation analysis could help improve communication was shown, by examining researches using conversation analysis not only for ordinary conversations but also for extraordinary or difficult conversations such as conversations between patients with dementia and their professional nurses. Conversation analysis can help in improving nursing communication by providing various structures and patterns as well as prototypes of conversation, and by suggesting specific problems and problem-solving strategies in communication.

  5. Improving communication between nuclear communities

    1995-01-01

    of an agreement between Paks Nuclear Power Station and several mayors of neighbouring villages. The mayors formed an Association for Social Control and Information, called in Hungarian TEIT. Steady flow of information on the plant reaches these villages. A round-the-clock background radiation monitoring station was also set up for the public in the near downwind town of Kalocsa, showing the situation every 10 minutes. Another anti-nuclear approach is to build up a 'Pavlovian type of conditioned reflex' in the population to make them afraid of nuclear energy. For example, Hungary is far from the sea, has no real nuclear problems, but you will find in Hungarian papers news on a sunken Soviet submarine. While not overlooking and underestimating the danger of such sunken submarine(s) it is worth mentioning that, such reports in our press in 1994 were three times greater than in 1992. It is important to recognize that in the former Soviet-influenced areas there are no basically professional nuclear communicators as compared to the Western countries. Therefore, I suggest, that a communication system be created by the nuclear community, probably named WANIS, World Association of Nuclear Information Specialists. A two-way International electronic mail system - built up similar to those run by the anti-nuclear forces - should help nuclear communicators of Central and Eastern Europe to exchange arguments and tactics against everyday arguments raised by anti-nuclear militants. In other words, a common armoury of arguments, I call 'Inter lingua Nucleare', should be created within the nuclear community to improve the countering of misleading, hostile statements and actions. In Hungary, the Hungarian Nuclear Society has launched a corrective programme. If very severely distorted opinions on nuclear electricity production or on nuclear techniques or on radiation appear in the media, the concerned Learned Societies (e.g. Energy, Nuclear Medicine, Food Science, Radiation Protection

    When the ionized upper atmosphere of the earth is illuminated by high-power HF radio waves at appropriate frequencies, the temperature of electrons in the ionosphere can be raised substantially. In addition, radio waves with sufficient energy cause parametric instabilities that generate a spectrum of intense plasma waves. Observations of these phenomena have produced new understanding of plasma processes. One consequence of heating and plasma wave generation is that irregularities are formed in the electron distribution which are aligned with the earth's magnetic field. Because of this, a scatterer of large radar cross section is produced, which scatters HF through UHF communication signals over long distance paths, that would not otherwise be normally possible by ionospheric means. Results of radio, radar, communication, and photometric experiments that explored the characteristics of the volume of ionosphere which has been intentionally modified, temporarily, above facilities near Boulder (Platteville), Colo., and at Arecibo, Puerto Rico are summarized

    2017-08-01

    HfO2 as a gate dielectric enables high electric field operation of SiC MIS structure and as gas sensor HfO2/SiC capacitors offer higher sensitivity than SiO2/SiC capacitors. The issue of higher density of oxygen vacancies and associated higher leakage current necessitates better passivation of HfO2/SiC interface. Effect of post deposition annealing in N2O plasma and post metallization annealing in forming gas on the structural and electrical characteristics of Pd/HfO2/SiC MIS capacitors are reported in this work. N2O plasma annealing suppresses crystallization during high temperature annealing thereby improving the thermal stability and plasma annealing followed by rapid thermal annealing in N2 result in formation of Hf silicate at the HfO2/SiC interface resulting in order of magnitude lower density of interface states and gate leakage current. Post metallization annealing in forming gas for 40 min reduces interface state density by two orders while gate leakage current density is reduced by thrice. Post deposition annealing in N2O plasma and post metallization annealing in forming gas are observed to be effective passivation techniques improving the electrical characteristics of HfO2/SiC capacitors.

    The aim of this study was to develop an evidence-based communication skills training workshop to improve the communication skills of critical care fellows. Pulmonary and critical care fellows (N = 38) participated in a 3-day communication skills workshop between 2008 and 2010 involving brief didactic talks, faculty demonstration of skills, and faculty-supervised small group skills practice sessions with simulated families. Skills included the following: giving bad news, achieving consensus on goals of therapy, and discussing the limitations of life-sustaining treatment. Participants rated their skill levels in a pre-post survey in 11 core communication tasks using a 5-point Likert scale. Of 38 fellows, 36 (95%) completed all 3 days of the workshop. We compared pre and post scores using the Wilcoxon signed rank test. Overall, self-rated skills increased for all 11 tasks. In analyses by participant, 95% reported improvement in at least 1 skill; with improvement in a median of 10 of 11 skills. Ninety-two percent rated the course as either very good/excellent, and 80% recommended that it be mandatory for future fellows. This 3-day communication skills training program increased critical care fellows' self-reported family meeting communication skills. Copyright © 2014 Elsevier Inc. All rights reserved.

    Although antiretroviral therapy has increased the survival of HIV-positive patients, traditional approaches to improving medication adherence have failed consistently. Acknowledging the role of communication in health behavior, we conducted a qualitative study to learn about patients' HIV treatment adherence experiences and to identify which communication strategies might influence adherence. Findings indicate that five constructs--cultural beliefs/language, stigma, cues to action, self-efficacy, and mood state--are potentially modifiable by improved communication. Results will be used to create a direct marketing campaign targeted to HIV-infected patients. Copyright © Taylor & Francis Group, LLC

    Nd2Fe14B-type permanent magnets have been widely applied in various fields such as wind power, voice coil motors, and medical instruments. The large temperature dependence of coercivity, however, limits their further applications. We have systematically investigated the magnetic properties, thermal stabilities and coercivity mechanisms of the (Pr0.2Nd0.8)13Fe81-xB6Hfx (x=0, 0.5) nanocrystalline magnets fabricated by a spark plasma sintering (SPS) technique. The results indicate that the influence of Hf addition is significant on magnetic properties and thermal stabilities of the (PrNd)2Fe14B-type sintered magnets. It is shown that the sample with x = 0.5 at 300 K has much higher coercivity and remanent magnetization than those counterparts without Hf. The temperature coefficients of remanence (α) and coercivity (β) of the (Pr0.2Nd0.8)13Fe81-xB6Hfx magnets are improved significantly from -0.23 %/K, -0.57 %/K for the sample at x = 0 to -0.17 %/K, -0.49 %/K for the sample at x = 0.5 in the temperature range of 300-400 K. Furthermore, it is found out that the domain wall pinning mechanism is more likely responsible for enhancing the coercivity of the (Pr0.2Nd0.8)13Fe81-xB6Hfx magnets.

    To capture communication patterns in operating room (OR) management to characterize the information needs of OR coordination. Technological applications can be used to change system processes to improve communication and information access, thereby decreasing errors and adverse events. The successful design of such applications relies on an understanding of communication patterns among healthcare professionals. Charge nurse communication was observed and documented at four OR suites at three tertiary hospitals. The data collection tool allowed rapid coding of communication patterns in terms of duration, mode, target person, and the purpose of each communication episode. Most (69.24%) of the 2074 communication episodes observed occurred face to face. Coordinating equipment was the most frequently occurring purpose of communication (38.7%) in all suites. The frequency of other purposes in decreasing order were coordinating patient preparedness (25.7%), staffing (18.8%), room assignment (10.7%), and scheduling and rescheduling surgery (6.2%). The results of this study suggest that automating aspects of preparing patients for surgery and surgical equipment management has the potential to reduce information exchange, decreasing interruptions to clinicians and diminishing the possibility of adverse events in the clinical setting.

    For the first time, it is demonstrated that nanoscale HfO2 surface passivation layers formed by atomic layer deposition (ALD) significantly improve the performance of Li ion batteries with SnO2-based anodes. Specifically, the measured battery capacity at a current density of 150 mAg -1 after 100 cycles is 548 and 853 mAhg-1 for the uncoated and HfO2-coated anodes, respectively. Material analysis reveals that the HfO2 layers are amorphous in nature and conformably coat the SnO2-based anodes. In addition, the analysis reveals that ALD HfO2 not only protects the SnO2-based anodes from irreversible reactions with the electrolyte and buffers its volume change, but also chemically interacts with the SnO2 anodes to increase battery capacity, despite the fact that HfO2 is itself electrochemically inactive. The amorphous nature of HfO2 is an important factor in explaining its behavior, as it still allows sufficient Li diffusion for an efficient anode lithiation/delithiation process to occur, leading to higher battery capacity. © 2014 WILEY-VCH Verlag GmbH & Co.

    This paper reports the simultaneous improvements in erase speed and data retention characteristics in flash memory using a stacked HfO 2 /Ta 2 O 5 charge-trapping layer. In comparison to a memory capacitor with a single HfO 2 trapping layer, the erase speed of a memory capacitor with a stacked HfO 2 /Ta 2 O 5 charge-trapping layer is 100 times faster and its memory window is enlarged from 2.7 to 4.8 V for the same ±16 V sweeping voltage range. With the same initial window of ΔV FB = 4 V, the device with a stacked HfO 2 /Ta 2 O 5 charge-trapping layer has a 3.5 V extrapolated 10-year retention window, while the control device with a single HfO 2 trapping layer has only 2.5 V for the extrapolated 10-year window. The present results demonstrate that the device with the stacked HfO 2 /Ta 2 O 5 charge-trapping layer has a strong potential for future high-performance nonvolatile memory application

    Highlights: • Post deposition annealing (PDA) and post metallization annealing (PMA) on the electrical characteristics of Pd/HfO{sub 2}/6H-SiC MIS capacitors. • Post deposition N{sub 2}O plasma annealing inhibits crystallization of HfO{sub 2} during high temperature annealing. • Plasma annealing followed by RTA in N{sub 2} results in formation of hafnium silicate at the HfO{sub 2}-SiC interface. • PDA reduces interface state density (D{sub it}) and gate leakage current density (J{sub g}) by order. • PMA in forming gas for 40 min results in better passivation and reduces D{sub it} by two orders and J{sub g} by thrice. - Abstract: HfO{sub 2} as a gate dielectric enables high electric field operation of SiC MIS structure and as gas sensor HfO{sub 2}/SiC capacitors offer higher sensitivity than SiO{sub 2}/SiC capacitors. The issue of higher density of oxygen vacancies and associated higher leakage current necessitates better passivation of HfO{sub 2}/SiC interface. Effect of post deposition annealing in N{sub 2}O plasma and post metallization annealing in forming gas on the structural and electrical characteristics of Pd/HfO{sub 2}/SiC MIS capacitors are reported in this work. N{sub 2}O plasma annealing suppresses crystallization during high temperature annealing thereby improving the thermal stability and plasma annealing followed by rapid thermal annealing in N{sub 2} result in formation of Hf silicate at the HfO{sub 2}/SiC interface resulting in order of magnitude lower density of interface states and gate leakage current. Post metallization annealing in forming gas for 40 min reduces interface state density by two orders while gate leakage current density is reduced by thrice. Post deposition annealing in N{sub 2}O plasma and post metallization annealing in forming gas are observed to be effective passivation techniques improving the electrical characteristics of HfO{sub 2}/SiC capacitors.

  20. Improving together: collaborative learning in science communication

    2015-04-01

    Most scientists today recognise that science communication is an important part of the scientific process. Despite this recognition, science writing and communication are generally taught outside the normal academic schedule. If universities offer such courses, they are generally short-term and intensive. On the positive side, such courses rarely fail to motivate. At no fault of their own, the problem with such courses lies in their ephemeral nature. The participants rarely complete a science communication course with an immediate and pressing need to apply these skills. And so the skills fade. We believe that this stalls real progress in the improvement of science communication across the board. Continuity is one of the keys to success! Whilst we wait for the academic system to truly integrate science communication, we can test and develop other approaches. We suggest a new approach that aims to motivate scientists to continue nurturing their communication skills. This approach adopts a collaborative learning framework where scientists form writing groups that meet regularly at different institutes around the world. The members of the groups learn, discuss and improve together. The participants produce short posts, which are published online. In this way, the participants learn and cement basic writing skills. These skills are transferrable, and can be applied to scientific articles as well as other science communication media. In this presentation we reflect on an ongoing project, which applies a collaborative learning framework to help young and early career scientists improve their writing skills. We see that this type of project could be extended to other media such as podcasts, or video shorts.

A concept of the wide-band multifunctional direction finder with integrated intercept and direction finding functions is presented. The direction finder should provide complete surveillance of the HF range and interception with direction finding of all active signals in given frequency range which are not shorter than 10 ms. The direction finder is the key element of the future automated radio reconnaissance system for the HF range, that should provide a complete insight of the signal activities in the HF range, which the existing communication intelligence system does not provide.

    2015-01-01

    The 'design for human factors' grounded theory explains 'how' human factors (HF) went from a reactive, after-injury programme in safety, to being proactively integrated into each step of the production design process. In this longitudinal case study collaboration with engineers and HF Specialists in a large electronics manufacturer, qualitative data (e.g. meetings, interviews, observations and reflections) were analysed using a grounded theory methodology. The central tenet in the theory is that when HF Specialists acclimated to the engineering process, language and tools, and strategically aligned HF to the design and business goals of the organisation, HF became a means to improve business performance. This led to engineers 'pulling' HF Specialists onto their team. HF targets were adopted into engineering tools to communicate HF concerns quantitatively, drive continuous improvement, visibly demonstrate change and lead to benchmarking. Senior management held engineers accountable for HF as a key performance indicator, thus integrating HF into the production design process. Practitioner Summary: Research and practice lack explanations about how HF can be integrated early in design of production systems. This three-year case study and the theory derived demonstrate how ergonomists changed their focus to align with design and business goals to integrate HF into the design process.

    In this work, amorphous indium-gallium-zinc oxide thin-film transistors (a-IGZO TFTs) with a HfO2 gate insulator and CF4 plasma treatment was demonstrated for the first time. Through the plasma treatment, both the electrical performance and reliability of the a-IGZO TFT with HfO2 gate dielectric were improved. The carrier mobility significantly increased by 80.8%, from 30.2 cm2/V∙s (without treatment) to 54.6 cm2/V∙s (with CF4 plasma treatment), which is due to the incorporated fluorine not only providing an extra electron to the IGZO, but also passivating the interface trap density. In addition, the reliability of the a-IGZO TFT with HfO2 gate dielectric has also been improved by the CF4 plasma treatment. By applying the CF4 plasma treatment to the a-IGZO TFT, the hysteresis effect of the device has been improved and the device’s immunity against moisture from the ambient atmosphere has been enhanced. It is believed that the CF4 plasma treatment not only significantly improves the electrical performance of a-IGZO TFT with HfO2 gate dielectric, but also enhances the device’s reliability.

    An enhanced time out is an improved communication process initiated to prevent such surgical errors as wrong-site, wrong-procedure, or wrong-patient surgery. The enhanced time out at my facility mandates participation from all members of the surgical team and requires designated members to respond to specified time out elements on the surgical safety checklist. The enhanced time out incorporated at my facility expands upon the safety measures from the World Health Organization's surgical safety checklist and ensures that all personnel involved in a surgical intervention perform a final check of relevant information. Initiating the enhanced time out at my facility was intended to improve communication and teamwork among surgical team members and provide a highly reliable safety process to prevent wrong-site, wrong-procedure, and wrong-patient surgery.

    The mode specific reactivity of the F + CHD{sub 3} → HF + CD{sub 3} reaction is investigated using an eight-dimensional quantum dynamical model on a recently developed ab initio based full-dimensional potential energy surface. Our results indicate prominent resonance structures at low collision energies and absence of an energy threshold in reaction probabilities. It was also found that excitation of the C–D stretching or CD{sub 3} umbrella mode has a relatively small impact on reactivity. On the other hand, the excitation of the C–H vibration (v{sub 1}) in CHD{sub 3} is shown to significantly increase the reactivity, which, like several recent quasi-classical trajectory studies, is at odds with the available experimental data. Possible sources of the disagreement are discussed.

    A GaN/Al 0.3 Ga 0.7 N/AlN/GaN high-electron mobility transistor utilizing a field plate (with a 0.3 μm overhang towards the drain and a 0.2 μm overhang towards the source) over a 165-nm sputtered HfO 2 insulator (HfO 2 -FP-HEMT) is fabricated on a sapphire substrate. Compared with the conventional field-plated HEMT, which has the same geometric structure but uses a 60-nm SiN insulator beneath the field plate (SiN-FP-HEMT), the HfO 2 -FP-HEMT exhibits a significant improvement of the breakdown voltage (up to 181 V) as well as a record field-plate efficiency (up to 276 V/μm). This is because the HfO 2 insulator can further improve the modulation of the field plate on the electric field distribution in the device channel, which is proved by the numerical simulation results. Based on the simulation results, a novel approach named the proportional design is proposed to predict the optimal dielectric thickness beneath the field plate. It can simplify the field-plated HEMT design significantly. (condensed matter: electronic structure, electrical, magnetic, and optical properties)

    Light-emitting diodes (LEDs) based on ZnO were fabricated on a p-Si substrate by using a pulsed laser deposition system. Significant electroluminescence (EL) improvement was demonstrated with the insertion of an HfO{sub 2} electron blocking layer (EBL) in n-ZnO/p-Si heterojunctions. Distinct near-band-edge emission at around 392 nm accompanying by a broadly strong visible emission was achieved when a proper thickness of HfO{sub 2} EBL was used. Current-voltage and capacitance-voltage measurements confirmed that a proper thickness of the HfO{sub 2} EBL can effectively balance the injection of electrons and holes, resulting in an increase of radiative recombination in the ZnO active layer and thus enhancing the EL performance of the devices. Five independent emissions corresponding to five different transition processes were proposed to clarify the EL origination of the n-ZnO/HfO{sub 2}/p-Si heterojunction LEDs by Gaussian deconvolutions. It is hoped that results in this work should be helpful for the development of ZnO-based LEDs that can integrate ZnO with the Si planar technology.

    Magnetic properties of melt spun Co{sub 86.5}Hf{sub 10.5}MB{sub 2} ribbons with refractory elements substitution (M=Cr, Nb, Ti, Zr) have been studied. For ternary Co{sub 86.5}Hf{sub 11.5}B{sub 2} ribbon, permanent magnetic properties of B{sub r}=0.71 T, {sub i}H{sub c}=192 kA/m, and (BH){sub max}=34.4 kJ/m{sup 3} are obtained, and they are significantly improved to B{sub r}=0.73–0.76 T, {sub i}H{sub c}=136–216 kA/m and (BH){sub max}=38.4–52.8 kJ/m{sup 3} with M substitution. Summarized with the results of x-ray diffraction refinement, thermal magnetic analysis, and transmission electron microscopy, the Co{sub 86.5}Hf{sub 10.5}MB{sub 2} nanocomposites following the optimal crystallization treatment mainly consist of orthorhombic 7:1 and face-center-cubic Co phases. Fine microstructure with average grain size in the range of 12.5−19.6 nm promotes exchange coupling effect between magnetic grains, thus improving permanent magnetic properties. The magnetic field dependence of coercivity reveals that coercivity of the studied Co{sub 86.5}Hf{sub 10.5}MB{sub 2} nonocomposites is mainly governed by the reverse domain nucleation mechanism. - Highlights: • M substitution refines the grain size. • M substitution strengthens the exchange coupling effect between grains. • M substitution improves hard magnetic properties of Co{sub 86.5}Hf{sub 10.5}MB{sub 2} ribbons. • The coercivity is mainly governed by the reverse domain nucleation mechanism. • Co{sub 86.5}Hf{sub 10.5}MB{sub 2} ribbons are relevant candidate for RE free permanent magnets.

    Sacubitril/valsartan is an angiotensin receptor-neprilysin inhibitor indicated for the treatment of patients with chronic heart failure (HF) with reduced ejection fraction; however, its mechanism of benefit remains unclear. Biomarkers that are linked to ventricular remodeling, myocardial injury, and fibrosis may provide mechanistic insight and important clinical guidance regarding sacubitril/valsartan use. This 52-week, multicenter, open-label, single-arm study is designed to (1) correlate biomarker changes with cardiac remodeling parameters, cardiovascular outcomes, and patient-reported outcome data and (2) determine short- and long-term changes in concentrations of biomarkers related to potential mechanisms of action and effects of sacubitril/valsartan therapy. Approximately 830 patients with HF with reduced ejection fraction will be initiated and titrated on sacubitril/valsartan according to United States prescribing information. Primary efficacy end points include the changes in N-terminal pro-B-type natriuretic peptide concentrations and cardiac remodeling from baseline to 1 year. Secondary end points include changes in concentrations of N-terminal pro-B-type natriuretic peptide and remodeling to 6 months, and changes in patient-reported outcomes using the Kansas City Cardiomyopathy Questionnaire-23 from baseline to 1 year. In addition, several other relevant biomarkers will be measured. Biomarker changes relative to the number of cardiovascular events in 12 months will also be assessed as exploratory end points. Results from the Prospective Study of Biomarkers, Symptom Improvement, and Ventricular Remodeling During Sacubitril/Valsartan Therapy for Heart Failure (PROVE-HF) will help establish a mechanistic understanding of angiotensin receptor-neprilysin inhibitor therapeutic benefits and provide clinicians with clarity on how to interpret information on biomarkers during treatment (PROVE-HF ClinicalTrials.gov identifier: NCT02887183).

    the world use low-bandwidth connections. Communicating science effectively includes efficient delivery of the information to the reader. To meet this criteria, responsive designs should also incorporate "mobile first" elements such as serving ideal image sizes (a low resolution cell phone does not need to receive a large desktop image) and a focus on fast, readable content delivery. The technical implementation of responsive web design is constantly changing as new web standards and approaches become available. However, fundamental design principles such as grid layouts, clear typography, and proper use of white space should be an important part of content delivery within any responsive design. This presentation will discuss current responsive design approaches for improving scientific communication across multiple devices, operating systems, and bandwidth capacities. The presentation will also include example responsive designs for scientific papers and websites. Implementing a responsive design approach with a focus on content and fundamental design principles is an important step to ensuring scientific information remains clear and accessible as screens and devices continue to evolve.

    Background Although it is taken for granted that history-taking and communication skills are learnable, this learning process should be confirmed by rigorous studies, such as randomized pre- and post-comparisons. The purpose of this paper is to analyse whether a communication course measurably improves the communicative competence of third-year medical students at a German medical school and whether technical or emotional aspects of communication changed differently. Method A sample of 32 randomly selected students performed an interview with a simulated patient before the communication course (pre-intervention) and a second interview after the course (post-intervention), using the Calgary-Cambridge Observation Guide (CCOG) to assess history taking ability. Results On average, the students improved in all of the 28 items of the CCOG. The 6 more technically-orientated communication items improved on average from 3.4 for the first interview to 2.6 in the second interview (p communication skills were not correlated (Pearson’s r = 0.03; n.s.). Conclusions Our communication course measurably improved communication skills, especially for female students. These improvements did not depend predominantly on an extension of the interview time. Obviously, “technical” aspects of communication can be taught better than “emotional” communication skills. PMID:22947372

    Objective. To examine whether standardized patient encounters led to an improvement in a student pharmacist-patient communication assessment compared to traditional active-learning activities within a classroom setting. Methods. A quasi-experimental study was conducted with second-year pharmacy students in a drug information and communication skills course. Student patient communication skills were assessed using high-stakes communication assessment. Results. Two hundred and twenty students' data were included. Students were significantly more likely to have higher scores on the communication assessment when they had higher undergraduate GPAs, were female, and taught using standardized patients. Similarly, students were significantly more likely to pass the assessment on the first attempt when they were female and when they were taught using standardized patients. Conclusion. Incorporating standardized patients within a communication course resulted in improved scores as well as first-time pass rates on a communication assessment than when using different methods of active learning.

    Use of effective interpersonal communication strategies by nurses in both personal and professional settings, may reduce stress, promote wellness, and therefore, improve overall quality of life. This article briefly explores the concept of interpersonal communication as it relates to Maslow's hierarchy of human needs; describes personal variables and the interaction of internal and external variables that can impact communication; and discusses possible causes and consequences of ineffective communication. Drawing on both the literature and experiences as a longtime provider of care in the mental health field, the author offers multiple practical strategies, with specific examples of possible responses for effective communication. Recommendations in this article are intended for nurses to consider as they seek healthy communication strategies that may be useful in both their personal and professional lives.

  14. Ultrathin HfON/SiO2 dual tunneling layer for improving the electrical properties of metal–oxide–nitride–oxide–silicon memory

    International Nuclear Information System (INIS)

    Liu, L.; Xu, J.P.; Chen, J.X.; Ji, F.; Huang, X.D.; Lai, P.T.

    2012-01-01

    A high-k gate stack structure with ultrathin HfON/SiO 2 as dual tunneling layer (DTL), AlN as charge storage layer (CSL) and HfAlO as blocking layer (BL) is proposed to make a charge-trapping-type metal–oxide–nitride–oxide–silicon non-volatile memory device by employing in-situ sputtering method. The validity of the structure is examined and confirmed by transmission electron microscopy. The memory window, program/erase, endurance and retention properties are investigated and compared with similar gate stack structure with Si 3 N 4 /SiO 2 as DTL, HfO 2 as CSL and Al 2 O 3 as BL. Results show that a large memory window of 3.55 V at a program/erase (P/E) voltage of + 8 V/− 15 V, high P/E speed, and good endurance and retention characteristic can be achieved using the Au/ HfAlO/AlN/(HfON/SiO 2 )/Si gate stack structure. The main mechanisms lie in the enhanced electron injection through the ultrathin high-k HfON/SiO 2 DTL with suitable band offset, high trapping efficiency of the high-k AlN material, and effective blocking role of the high-k HfAlO BL. - Highlights: ► An Au/HfAlO/AlN/(HfON/SiO 2 )/Si high-k gate stack structure is proposed. ► A band-engineered dual tunneling layer (HfON/SiO 2 ) is proposed and prepared. ► A good trade-off among the memory characteristics is obtained. ► In-situ sputtering method is employed to fabricate the gate stack structure.

  15. Improving Communication Skills in Early Career Scientists

    2013-12-01

    The AGU fall meeting is a time for scientists to share what we have been hard at work on for the past year, to share our trials and tribulations, and of course, to share our science (we hope inspirational). In addition to sharing, the AGU fall meeting is also about collaboration as it brings old and new colleagues together from diverse communities across the planet. By sharing our ideas and findings, we build new relationships with the potential to cross boundaries and solve complex and pressing environmental issues. With ever emerging and intensifying water scarcity, extreme weather, and water quality issues across the plant, it is especially important that scientists like us share our ideas and work together to put these ideas into action. My vision of the future of water sciences embraces this fact. I believe that better training is needed to help early career scientists, like myself, build connections within and outside of our fields. First and foremost, more advanced training in effective storytelling concepts and themes may improve our ability to provide context for our research. Second, training in the production of video for internet-based media (e.g. YouTube) may help us bring our research to audiences in a more personalized way. Third, opportunities to practice presenting at highly visible public events such as the AGU fall meeting, will serve to prepare early career scientists for a variety of audiences. We hope this session, ';Water Sciences Pop-Ups', will provide the first steps to encourage and train early career scientists as they share and collaborate with scientists and non-scientists around the world.

    The effects of atomic layer deposition (ALD) conditions for the HfO2 gate insulators (GI) on the device characteristics of the InGaZnO (IGZO) thin film transistors (TFTs) were investigated when the ALD temperature and Hf precursor purge time were varied to 200, 225, and 250 °C, and 15 and 30 s, respectively. The HfO2 thin films showed low leakage current density of 10-8 A cm-2, high dielectric constant of over 20, and smooth surface roughness at all ALD conditions. The IGZO TFTs using the HfO2 GIs showed good device characteristics such as a saturation mobility as high as 11 cm2 V-1 s-1, a subthreshold swing as low as 0.10 V/dec, and all the devices could be operated at a gate voltage as low as  ±3 V. While there were no marked differences in transfer characteristics and PBS stabilities among the fabricated devices, the NBIS instabilities could be improved by increasing the ALD temperature for the formation of HfO2 GIs by reducing the oxygen vacancies within the IGZO channel.

  18. A Wireless Text Messaging System Improves Communication for Neonatal Resuscitation.

    Hughes Driscoll, Colleen A; Schub, Jamie A; Pollard, Kristi; El-Metwally, Dina

    Handoffs for neonatal resuscitation involve communicating critical delivery information (CDI). The authors sought to achieve ≥95% communication of CDI during resuscitation team requests. CDI included name of caller, urgency of request, location of delivery, gestation of fetus, status of amniotic fluid, and indication for presence of the resuscitation team. Three interventions were implemented: verbal scripted handoff, Spök text messaging, and Engage text messaging. Percentages of CDI communications were analyzed using statistical process control. Following implementation of Engage, the communication of all CDI, except for indication, was ≥95%; communication of indication occurred 93% of the time. Control limits for most CDI were narrower with Engage, indicating greater reliability of communication compared to the verbal handoff and Spök. Delayed resuscitation team arrival, a countermeasure, was not higher with text messaging compared to verbal handoff ( P = 1.00). Text messaging improved communication during high-risk deliveries, and it may represent an effective tool for other delivery centers.

    The use of a new HF-resistant tandem spray chamber arrangement consisting of a cyclonic spray chamber and a Scott-type spray chamber made from PFA and PEEK provides a straightforward approach for improving the performance of inductively coupled-mass spectrometry (ICP-MS). The characteristics of the tandem spray chamber were critically evaluated against a PEEK cyclonic and a PFA Scott-type spray chamber, respectively. Sensitivity across the entire mass range was increased by about three times compared to the conventional setup utilizing only one spray chamber. Precision of the results, especially at low signal intensities, improved by 160% and 31% compared to the cyclonic and Scott-type spray chamber, respectively. Using the tandem spray chamber, the oxide formation rate was lowered by about 50%. Signals as low as 30 counts could be determined under routine measurement conditions with a RSD of 2.4% thus allowing to precisely quantify small concentration differences at the ng l -1 concentration level. The excellent precision (0.02-0.07%) of 206 Pb / 207 Pb and 206 Pb / 208 Pb ratios determined in pore water samples was rather limited by the instrumental capabilities of the single collector ICP-MS instrument than by the performance of the tandem spray chamber

    Skilled physician communication is a key component of patient experience. Large-scale studies of exposure to communication skills training and its impact on patient satisfaction have not been conducted. We aimed to examine the impact of experiential relationship-centered physician communication skills training on patient satisfaction and physician experience. This was an observational study. The study was conducted at a large, multispecialty academic medical center. Participants included 1537 attending physicians who participated in, and 1951 physicians who did not participate in, communication skills training between 1 August 2013 and 30 April 2014. An 8-h block of interactive didactics, live or video skill demonstrations, and small group and large group skills practice sessions using a relationship-centered model. Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS), Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CGCAHPS), Jefferson Scale of Empathy (JSE), Maslach Burnout Inventory (MBI), self-efficacy, and post course satisfaction. Following the course, adjusted overall CGCAHPS scores for physician communication were higher for intervention physicians than for controls (92.09 vs. 91.09, p communication scores (83.95 vs. 82.73, p = 0.22). Physicians reported high course satisfaction and showed significant improvement in empathy (116.4 ± 12.7 vs. 124 ± 11.9, p communication skills training improved patient satisfaction scores, improved physician empathy, self-efficacy, and reduced physician burnout. Further research is necessary to examine longer-term sustainability of such interventions.

    2010-03-01

    The wet etching properties of a HfSiON high-k dielectric in HF-based solutions are investigated. HF-based solutions are the most promising wet chemistries for the removal of HfSiON, and etch selectivity of HF-based solutions can be improved by the addition of an acid and/or an alcohol to the HF solution. Due to densification during annealing, the etch rate of HfSiON annealed at 900 °C for 30 s is significantly reduced compared with as-deposited HfSiON in HF-based solutions. After the HfSiON film has been completely removed by HF-based solutions, it is not possible to etch the interfacial layer and the etched surface does not have a hydrophobic nature, since N diffuses to the interface layer or Si substrate formation of Si-N bonds that dissolves very slowly in HF-based solutions. Existing Si-N bonds at the interface between the new high-k dielectric deposit and the Si substrate may degrade the carrier mobility due to Coulomb scattering. In addition, we show that N2 plasma treatment before wet etching is not very effective in increasing the wet etch rate for a thin HfSiON film in our case.

    This article describes a novel communication audit conducted with those concerned with the practice placements of pre-registration Nursing students. The study, uniquely, addressed all who were involved in communication concerning placement in what is described as an organisational analysis. The aim of the audit was to identify levels of satisfaction and dissatisfaction with present communication processes and to identify points for improvement. The audit used the Hogard-Barker Communication Audit of Practice a customized version of a well established tool, devised to cover issues relevant to practice placements. A key feature of the tool is the opportunity for participants to identify the amount of communication they are receiving on particular topics and issues against the amount they would like to receive. Participants in the audit included students, assessor mentors, ward managers, clinical facilitators and link tutors. Overall there was considerable dissatisfaction with what was perceived to be the insufficient amount of communication received on a number of topics including allocations, the curriculum, students' learning outcomes and commitments in terms of college work. In addition to identifying points for improvement the audit provides a baseline against which progress can be assessed through a future audit.

    Effective communication, co-operation and teamwork have been identified as key determinants of patient safety. SBAR (Situation, Background, Assessment and Recommendation) is a communication tool recommended by the World Health Organization and the UK National Health Service. SBAR is a structured method for communicating critical information that requires immediate attention and action, contributing to effective escalation of management and increased patient safety. To our knowledge, this is the first study showing use of SBAR in South Africa (SA). To determine the effectiveness of adopting the SBAR communication tool in an acute clinical setting in SA. In the first phase of this study, neonatal nurses and doctors at Groote Schuur Hospital, Cape Town, were gathered in a focus group and given a questionnaire asking about communication in the neonatal department. Neonatal nurses and doctors were then trained to use SBAR. A telephone audit demonstrated an increase in SBAR use by registrars from 29% to 70% when calling consultants for help. After training, the majority of staff agreed that SBAR had helped with communication, confidence, and quality of patient care. There was qualitative evidence that SBAR led to greater promptness in care of acutely ill patients. Adopting SBAR was associated with perceived improvement in communication between professionals and in the quality and safety of patient care. It is suggested that this simple tool be introduced to many other hospitals in SA.

    When oncology nurses have strong communication skills, they play a pivotal role in influencing patient satisfaction, adherence to plans of care, and overall clinical outcomes. However, research studies indicate that nurses tend to keep communication with patients and families at a superficial, nontherapeutic level. Processes for teaching goals-of-care communication skills and for implementing skills into clinical practice are not clearly defined. Nurses at a large comprehensive cancer center recognized the need for help with this skill set and sought out communication experts to assist in providing the needed education. An educational project was developed to improve therapeutic communication skills in oncology nurses during goals-of-care discussions and giving bad news. The program was tailored to nurses and social workers providing care to patients in a busy, urban, academic, outpatient oncology setting. Program topics included exploring the patient's world, eliciting hopes and concerns, and dealing with conflict about goals. Sharing and discussing specific difficult questions and scenarios were encouraged throughout the program. The program was well attended and well received by oncology nurses and social workers. Participants expressed interest in the continuation of communication programs to further enhance skills.

    Increased exposure to volcanic hazard, particularly at vulnerable small islands, is driving an urgent and growing need for improved communication between monitoring scientists, emergency managers and the media, in advance of and during volcanic crises. Information gathering exercises undertaken on volcanic islands (Guadeloupe, St. Vincent and Montserrat) in the Lesser Antilles (eastern Caribbean), which have recently experienced - or are currently experiencing - volcanic action, have provided the basis for the compilation and publication of a handbook on Communication During Volcanic Emergencies, aimed at the principal stakeholder groups. The findings of the on-island surveys point up the critical importance of (1) bringing together monitoring scientists, emergency managers, and representatives of the media, well in advance of a volcanic crisis, and (2), ensuring that procedures and protocols are in place that will allow, as far as possible, effective and seamless cooperation and coordination when and if a crisis situation develops. Communication During Volcanic Emergencies is designed to promote and encourage both of these priorities through providing the first source-book addressing working relationships and inter-linkages between the stakeholder groups, and providing examples of good and bad practice. While targeting the volcanic islands of the eastern Caribbean, the source-book and its content are largely generic, and the advice and guidelines contained therein have equal validity in respect of improving communication before and during crises at any volcano, and have application to the communication issue in respect of a range of other geophysical hazards.

Studies suggest that these conversations are associated with improved outcomes for patients and their families, enhanced clinician satisfaction, and lower health care costs; however, the role of primary care clinicians in driving conversations about goals and priorities in serious illness is not well defined. To present a review of a structured search of the evidence base about communication in serious illness in primary care. MEDLINE was searched, via PubMed, on January 19, 2016, finding 911 articles; 126 articles were reviewed and selected titles were added from bibliography searches. Review of the literature informed 2 major topic areas: the role of primary care in communication about serious illness and clinician barriers and system failures that interfere with effective communication. Literature regarding the role that primary care plays in communication focused primarily on the ambiguity about whether primary care clinicians or specialists are responsible for initiating conversations, the benefits of primary care clinicians and specialists conducting conversations, and the quantity and quality of discussions. Timely and effective communication about serious illness in primary care is hampered by key clinician barriers, which include deficits in knowledge, skills, and attitudes; discomfort with prognostication; and lack of clarity about the appropriate timing and initiation of conversations. Finally, system failures in coordination, documentation, feedback, and quality improvement contribute to lack of conversations. Clinician and system barriers will challenge primary care clinicians and institutions to meet the needs of patients with serious illness. Ensuring that conversations about goals and values occur at the appropriate time for seriously ill patients will

    The subjects under investigation were the ''Shift book'', ''Simulation book'', and ''Technical and organisational changes and their records''. It was intended to analyse both the communication processes and the associated written documentation in order to determine areas for potential improvement and possibilities for standardization. Information was obtained by interviewing shift members and their supervisors, by general observation, and by compilation and evaluation of the extensive dokumentation. Assessment criteria were developed on a scientific basis and in the course of the investigation, in particular from ergonomic findings, as well as from standards and regulations and comparison between the plants. General practical suggestions were developed for the improvement of the communication forms and the formal design of the documents and their contents. The transfer of the recommendations to practical use in the plants presupposes the consideration of plant-specific frames of reference. The report includes a compilation and listing of suggestions for improvement in topical subdivisions. (orig.) [de

    The literature suggests that many individuals diagnosed with Autism Spectrum Disorder (ASD) experience challenges with recognizing and describing emotions in others, which may result in difficulties with the verbal expression of empathy during communication. Thus, there is a need for intervention techniques targeting this area. Using a multiple baseline across participants design, this study examined the effectiveness of a video-feedback intervention with a visual framework component to improve verbal empathetic statements and questions during conversation for adults with ASD. Following intervention, all participants improved in verbal expression of empathetic statements and empathetic questions during conversation with generalization and maintenance of gains. Furthermore, supplemental assessments indicated that each participant improved in their general level of empathy and confidence in communication skills.

  10. Communication Styles of Interactive Tools for Self-Improvement.

    Niess, Jasmin; Diefenbach, Sarah

    Interactive products for self-improvement (e.g., online trainings to reduce stress, fitness gadgets) have become increasingly popular among consumers and healthcare providers. In line with the idea of positive computing, these tools aim to support their users on their way to improved well-being and human flourishing. As an interdisciplinary domain, the design of self-improvement technologies requires psychological, technological, and design expertise. One needs to know how to support people in behavior change, and one needs to find ways to do this through technology design. However, as recent reviews show, the interlocking relationship between these disciplines is still improvable. Many existing technologies for self-improvement neglect psychological theory on behavior change, especially motivational factors are not sufficiently considered. To counteract this, we suggest a focus on the dialog and emerging communication between product and user, considering the self-improvement tool as an interactive coach and advisor. The present qualitative interview study (N = 18) explored the user experience of self-improvement technologies. A special focus was on the perceived dialog between tool and user, which we analyzed in terms of models from communication psychology. Our findings show that users are sensible to the way the product "speaks to them" and consider this as essential for their experience and successful change. Analysis revealed different communication styles of self-improvement tools (e.g., helpful-cooperative, rational-distanced, critical-aggressive), each linked to specific emotional consequences. These findings form one starting point for a more psychologically founded design of self-improvement technology. On a more general level, our approach aims to contribute to a better integration of psychological and technological knowledge, and in consequence, supporting users on their way to enhanced well-being.

    Full Text Available This research can be described as an experimental quantitative one including: a strategy training; two homogenous experimental groups with different levels of proficiency; and two homogenous control groups. The subjects are 60 Spanish high school students, who have been selected after taking the Oxford Quick Placement-Test. The study aims at investigating the possible relationship between the effect of the strategy training and the subjects' level of proficiency. It is also designed to analyze the effect of the training on the use of communication strategies in the written medium. It is meant to study the effect of the strategy training on the subjects' writing skill in English. The results show that the students' level of proficiency exerts a strong effect on the subjects' use of written communication strategies (CSs and on their strategy preference in written production. They also demonstrate how strategy training improves the subjects' written communication ability.

    Difficult conversations in medical care often occur between physicians and patients' surrogates, individuals entrusted with medical decisions for patients who lack the capacity to make them. Poor communication between patients' surrogates and physicians may exacerbate anxiety and guilt for surrogates, and may contribute to physician stress and burnout. This pilot study assesses the effectiveness of an experiential learning workshop that was conducted in a clinical setting, and aimed at improving resident physician communication skills with a focus on surrogate decision-making. From April through June 2016, we assessed internal medicine residents' baseline communication skills through an objective structured clinical examination (OSCE) with actors representing standardized surrogates. After an intensive, 6-hour communication skills workshop, residents were reassessed via an OSCE on the same day. A faculty facilitator and the surrogate evaluated participants' communication skills via the expanded Gap Kalamazoo Consensus Statement Assessment Form. Wilcoxon signed rank tests (α of .05) compared mean pre- and postworkshop scores. Of 44 residents, 33 (75%) participated. Participants' average preworkshop OSCE scores ( M  = 3.3, SD = 0.9) were significantly lower than postworkshop scores ( M  = 4.3; SD = 0.8; Z  = 4.193; P  decision-making benefit from focused interventions. Our pilot assessment of a workshop showed promise, and additionally demonstrated the feasibility of bringing OSCEs and simulated encounters into a busy clinical practice.

    Patient portals (ie, secure web-based services for patient health record access) and secure messaging to health care professionals are gaining popularity slowly. Advantages of web portals include timely communication and instruction, access to appointments and other services, and high patient satisfaction. Limitations include inappropriate use, security considerations, organizational costs, and exclusion of patients who are uncomfortable with or unable to use computers. Attention to the organization's strategic plan and office policies, patient and staff expectations, workflow and communication integration, training, marketing, and enrollment can facilitate optimal use of this technology. Other communication technologies that can enhance patient care include automated voice or text reminders and brief electronic communications. Social media provide another method of patient outreach, but privacy and access are concerns. Incorporating telehealthcare (health care provided via telephone or Internet), providing health coaching, and using interactive health communication applications can improve patient knowledge and clinical outcomes and provide social support.

    Clients' acceptance and adherence with orthoses can be influenced by a clinician's communication skills. In this clinical note, we describe two communication techniques, in the context of therapeutic footwear. Person-centred communication involves engaging with and listening to the attitudes of the client towards their condition, as well as discussing acceptance and expectations, in a structured consultation. Building a relationship is crucial and requires clients to feel heard and understood. An important influence on the acceptance and adherence is that a client makes a conscious decision to receive their device. This active receipt can be facilitated through shared decision making, wherein clinicians give clear, relevant and meaningful examples, based on clinical evidence, and ensure this is understood. Two communication techniques for clinicians providing therapeutic footwear are described. These can be adapted for use with provision of other assistive technologies to improve client acceptance and adherence. Clinical relevance Small changes in how clinicians communicate to their clients in daily practice can have a big influence on the subsequent acceptance and adherence with therapeutic footwear and indeed other prescribed assistive technologies.

    To conduct a systematic review of the literature to identify, describe and assess interventions of information and communication technology on the processes of communication and associated patient outcomes within hospital settings. Studies published from the years 1996 to 2010 were considered and were selected if they described an evaluation of information and communication technology interventions to improve clinical communication within hospitals. Two authors abstracted data from full text articles, and the quality of individual articles were appraised. Results of interventions were summarized by their effect. There were 18 identified studies that evaluated the use of interventions that included alphanumeric paging, hands-free communication devices, mobile phones, smartphones, task management systems and a display based paging system. Most quantitative studies used a before and after study design and were of lower quality. Of all the studies, there was only one prospective randomized study, but this study used only simulated communication events. Quantitative studies identified improved perceptions of communication and some improvement in communication metrics. Qualitative studies described improvements in efficiency of communication but also issues of loss of control and reliability. Despite the rapid advancement in information and communications technology over the last decade, there is limited evidence suggesting improvements in the ability of health professionals to communicate effectively. Given the critical nature of communication, we advocate further evaluation of information and communication technology designed to improve communication between clinicians. Outcome measures should include measures of patient-oriented outcomes and efficiency for clinicians. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Three coding schemes designed for improved data communication are evaluated. Four block codes are evaluated relative to a quality function, which is a function of both the amount of data rejected and the error rate. The Viterbi maximum likelihood decoding algorithm as a decoding procedure is reviewed. This evaluation is obtained by simulating the system on a digital computer. Short constraint length rate 1/2 quick-look codes are studied, and their performance is compared to general nonsystematic codes.

    Interdisciplinary communication at a Veterans Affairs (VA) academic teaching hospital is largely dependent on alphanumeric paging, which has limitations as a result of one-way communication and lack of reliable physician identification. Adverse patient outcomes related to difficulty contacting the correct consulting provider in a timely manner have been reported. House officers were surveyed on the level of satisfaction with the current VA communication system and the rate of perceived adverse patient outcomes caused by potential delays within this system. Respondents were then asked to identify the ideal paging system. These results were used to develop and deploy a new Web site. A postimplementation survey was repeated 1 year later. This study was conducted as a quality improvement project. House officer satisfaction with the preintervention system was 3%. The majority used more than four modalities to identify consultants, with 59% stating that word of mouth was a typical source. The preferred mode of paging was the university hospital paging system, a Web-based program that is used at the partnering academic institution. Following integration of VA consulting services within the university hospital paging system, the level of satisfaction improved to 87%. Significant decreases were seen in perceived adverse patient outcomes (from 16% to 2%), delays in patient care (from 90% to 16%), and extended hospitalizations (from 46% to 4%). Our study demonstrates significant improvement in physician satisfaction with a newly implemented paging system that was associated with a decreased perceived number of adverse patient events and delays in care.

    Worldwide, programs to improve udder health are implemented using communication tools and methods that inform and persuade dairy farmers. This study evaluated 2 communication strategies used in a mastitis control program in the Netherlands. To improve farmers' udder health management, tools such as instruction cards, treatment plans, checklists and software were developed following an argument-based comprehensive "central route." These tools were used during on-farm study group meetings for farmers organized by veterinarians and also during individual veterinarian-farmer interactions. The second strategy aimed at adopting a single management practice to increase the use of milking gloves during milking. This approach followed a straightforward "peripheral" route that used implicit persuasion techniques. Results of an online survey of 374 Dutch dairy farmers showed that most farmers were able and willing to use the educational management tools to increase udder health on their farms. They evaluated the tools positively regardless of the mastitis problems on their farms. This seems to indicate that the central route of communication is most effective when farmers are motivated to work on udder health in general. Results of repeated random telephone surveys before, during, and after the campaign on the use of milking gloves showed that the use of gloves increased from 20.9 to 42.0% of the respondents. Respondents' opinions about milking gloves also changed favorably, indicating that a relatively short peripheral campaign on a single action can have a sustained effect on farmers' behavior. Both communication strategies seem to be potentially successful in disseminating knowledge to a specific target group of farmers and in changing that group's behavior. However, to reach as many farmers as possible, the strategies should be combined. When optimizing these strategies, both the farmers' motivation to work on udder health and the aim of the campaign should be considered

    Nurses communicating with patients who are unable to speak often lack access to tools and technologies to support communication. Although mobile communication technologies are ubiquitous, it is not known whether their use to support communication is feasible on a busy hospital ward. The aim of this study was to determine the views of hospital nurses on the feasibility of using mobile communication technologies to support nurse-patient communication with individuals who have communication impairments. This study involved an online survey followed by a focus group, with findings analyzed across the two data sources. Nurses expected that mobile communication devices could benefit patient care but lacked access to these devices, encountered policies against use, and held concerns over privacy and confidentiality. The use of mobile communication technologies with patients who have communication difficulties is feasible and may lead to improvements in communication and care, provided environmental barriers are removed and facilitators enhanced.

    We elected to explore emerging consumer technologies that can be adopted to improve and facilitate image and data communication in medical and clinical environment. The wide adoption of new communication paradigm such as instant messaging, chatting and direct emailing can be integrated in specific applications. The increasing capacity of portable and hand held devices such as iPod music players offer an attractive alternative for data storage that exceeds the capabilities of traditional offline storage media such as CD or even DVD. We adapted medical image display and manipulation software called OSIRIX to integrate different innovative technologies facilitating the communication and data transfer between remote users. We integrated email and instant messaging features to the program allowing users to instantaneously email an image or a set of images that are displayed on the screen. Using iChat instant messaging application from Apple a user can share the content of his screen with a remote correspondent and communicate in real time using voice and video. To provide convenient mechanism for exchange of large data sets the program can store the data in DICOM format on CD or DVD, but was also extended to use the large storage capacity of iPod hard disks as well as Apple"s online storage service "dot Mac" that users can subscribe to benefit from scalable secure storage that accessible from anywhere on the internet. The adoption of these innovative technologies is likely to change the architecture of traditional picture archiving and communication systems and provide more flexible and efficient means of communication.

    Vaccination is a cost-effective public health measure and is central to the Millennium Development Goal of reducing child mortality. However, childhood vaccination coverage remains sub-optimal in many settings. While communication is a key feature of vaccination programmes, we are not aware of any comprehensive approach to organising the broad range of communication interventions that can be delivered to parents and communities to improve vaccination coverage. Developing a classification system (taxonomy) organised into conceptually similar categories will aid in: understanding the relationships between different types of communication interventions; facilitating conceptual mapping of these interventions; clarifying the key purposes and features of interventions to aid implementation and evaluation; and identifying areas where evidence is strong and where there are gaps. This paper reports on the development of the 'Communicate to vaccinate' taxonomy. The taxonomy was developed in two stages. Stage 1 included: 1) forming an advisory group; 2) searching for descriptions of interventions in trials (CENTRAL database) and general health literature (Medline); 3) developing a sampling strategy; 4) screening the search results; 5) developing a data extraction form; and 6) extracting intervention data. Stage 2 included: 1) grouping the interventions according to purpose; 2) holding deliberative forums in English and French with key vaccination stakeholders to gather feedback; 3) conducting a targeted search of grey literature to supplement the taxonomy; 4) finalising the taxonomy based on the input provided. The taxonomy includes seven main categories of communication interventions: inform or educate, remind or recall, teach skills, provide support, facilitate decision making, enable communication and enhance community ownership. These categories are broken down into 43 intervention types across three target groups: parents or soon-to-be-parents; communities, community

  6. Revised scoring and improved reliability for the Communication Patterns Questionnaire.

    The Communication Patterns Questionnaire (CPQ; Christensen, 1987) is a widely used self-report measure of couple communication behavior and is well validated for assessing the demand/withdraw interaction pattern, which is a robust predictor of poor relationship and individual outcomes (Schrodt, Witt, & Shimkowski, 2014). However, no studies have examined the CPQ's factor structure using analytic techniques sufficient by modern standards, nor have any studies replicated the factor structure using additional samples. Further, the current scoring system uses fewer than half of the total items for its 4 subscales, despite the existence of unused items that have content conceptually consistent with those subscales. These characteristics of the CPQ have likely contributed to findings that subscale scores are often troubled by suboptimal psychometric properties such as low internal reliability (e.g., Christensen, Eldridge, Catta-Preta, Lim, & Santagata, 2006). The present study uses exploratory and confirmatory factor analyses on 4 samples to reexamine the factor structure of the CPQ to improve scale score reliability and to determine if including more items in the subscales is warranted. Results indicate that a 3-factor solution (constructive communication and 2 demand/withdraw scales) provides the best fit for the data. That factor structure was confirmed in the replication samples. Compared with the original scales, the revised scales include additional items that expand the conceptual range of the constructs, substantially improve reliability of scale scores, and demonstrate stronger associations with relationship satisfaction and sensitivity to change in therapy. Implications for research and treatment are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  7. Reliability Improved Cooperative Communication over Wireless Sensor Networks

    Full Text Available With the development of smart devices and connection technologies, Wireless Sensor Networks (WSNs are becoming increasingly intelligent. New or special functions can be obtained by receiving new versions of program codes to upgrade their software systems, forming the so-called smart Internet of Things (IoT. Due to the lossy property of wireless channels, data collection in WSNs still suffers from a long delay, high energy consumption, and many retransmissions. Thanks to wireless software-defined networks (WSDNs, software in sensors can now be updated to help them transmit data cooperatively, thereby achieving more reliable communication. In this paper, a Reliability Improved Cooperative Communication (RICC data collection scheme is proposed to improve the reliability of random-network-coding-based cooperative communications in multi-hop relay WSNs without reducing the network lifetime. In WSNs, sensors in different positions can have different numbers of packets to handle, resulting in the unbalanced energy consumption of the network. In particular, nodes in non-hotspot areas have up to 90% of their original energy remaining when the network dies. To efficiently use the residual energy, in RICC, high data transmission power is adopted in non-hotspot areas to achieve a higher reliability at the cost of large energy consumption, and relatively low transmission power is adopted in hotspot areas to maintain the long network lifetime. Therefore, high reliability and a long network lifetime can be obtained simultaneously. The simulation results show that compared with other scheme, RICC can reduce the end-to-end Message Fail delivering Ratio (MFR by 59.4%–62.8% under the same lifetime with a more balanced energy utilization.

    Medical stores management in hospitals is a tedious and time consuming chore with limited resources tasked for the purpose and poor penetration of Information Technology. The process of automation is slow paced due to various inherent factors and is being challenged by the increasing inventory loads and escalating budgets for procurement of drugs. We carried out an indepth case study at the Medical Stores of a tertiary care health care facility. An iterative six step Quality Improvement (QI) process was implemented based on the Plan-Do-Study-Act (PDSA) cycle. The QI process was modified as per requirement to fit the medical stores management model. The results were evaluated after six months. After the implementation of QI process, 55 drugs of the medical store inventory which had expired since 2009 onwards were replaced with fresh stock by the suppliers as a result of effective communication through upgraded database management. Various pending audit objections were dropped due to the streamlined documentation and processes. Inventory management improved drastically due to automation, with disposal orders being initiated four months prior to the expiry of drugs and correct demands being generated two months prior to depletion of stocks. The monthly expense summary of drugs was now being done within ten days of the closing month. Improving communication systems within the hospital with vendor database management and reaching out to clinicians is important. Automation of inventory management requires to be simple and user-friendly, utilizing existing hardware. Physical stores monitoring is indispensable, especially due to the scattered nature of stores. Staff training and standardized documentation protocols are the other keystones for optimal medical store management.

  10. Improving Climate Communication through Comprehensive Linguistic Analyses Using Computational Tools

    2014-12-01

    An important lesson on climate communication research is that there is no single way to reach out and inform the public. Different groups conceptualize climate issues in different ways and different groups have different values and assumptions. This variability makes it extremely difficult to effectively and objectively communicate climate information. One of the main challenges is the following: How do we acquire a better understanding of how values and assumptions vary across groups, including political groups? A necessary starting point is to pay close attention to the linguistic content of messages used across current popular media sources. Careful analyses of that information—including how it is realized in language for conservative and progressive media—may ultimately help climate scientists, government agency officials, journalists and others develop more effective messages. Past research has looked at partisan media coverage of climate change, but little attention has been given to the fine-grained linguistic content of such media. And when researchers have done detailed linguistic analyses, they have relied primarily on hand-coding, an approach that is costly, labor intensive, and time-consuming. Our project, building on recent work on partisan news media (Gann & Matlock, 2014; under review) uses high dimensional semantic analyses and other methods of automated classification techniques from the field of natural language processing to quantify how climate issues are characterized in media sources that differ according to political orientation. In addition to discussing varied linguistic patterns, we share new methods for improving climate communication for varied stakeholders, and for developing better assessments of their effectiveness.

  11. Improving emotive communication: verbal, prosodic and kinesic conflictavoidance techniques

    Full Text Available Industrial language programme developers who wish to improve emotive communication and reduce supervisor-worker conflicts can profit from recent research by interactional psychologists, social psychologists and investigators of nonverbal communication. Three emotive aspects of speech are central to conflict-avoidance: levels of assertiveness, interpersonal involvement and emotional intensity. In face-to-face speech these are signalled by various verbal, vocal and kinesic activities. Conflict-avoidance is largely a matter of impression management. A supervisor who wishes to avoid unnecessary conflicts actively maintains a supportive communicative environment. When delivering positive messages he is assertive, interpersonally involved, and more emotional than usual. When delivering negative messages he is relatively nonassertive, impersonal and unemotional. Multimodal techniques for avoiding conflicts in various industrial settings are discussed in the paper. Die samestellers van industriele taalprogramme wat daarna mik om emotiewe kommunikasie te verbeter en om opsiener/werker-konflik te verminder, sal baat vind by resente navorsing deur interaksie-psigoloe, sosiale psigoloe en ondersoekers na nie-verbale kommunikasie. Drie emotiewe aspekte van spraak staan sentraal in die vermyding van konflik: vlakke van selfgelding, interpersoonlike betrokkenheid en emosionele intensiteit. In gesprekke van aangesig tot aangesig word hierdie aspekte oorgedra deur verskeie verbale, vokale en kinestetiese aktiwiteite. Om konflik te vermy hang in 'n groot mate saam met die skep van 'n positiewe indruk. 'n Opsiener wat graag onnodige konflik wil vermy, skep op aktiewe wyse 'n ondersteunende kommunikatiewe omgewing. Wanneer hy positiewe boodskappe oordra, doen hy dit met gesag, hy is interpersoonlik betrokke en meer emosioneel as gewoonlilc Met die oordra van negatiewe boodskappe is hy relatief onaanmatigend, onpersoonlik en onemosioneel.

    While many undergraduate Atmospheric Science departments are expanding their curriculums to focus on the science of climate change, often overlooked is the need to educate students about how this topic can be effectively communicated to others. It has become increasingly difficult for young scientists to comfortably discuss this polarizing topic with people outside of the classroom. To address this, Atmospheric Science faculty at Lyndon State College are providing undergraduate students the opportunity to practice this important skill by reaching out to the local community. Over the past year, students have been meeting regularly to discuss climate change and its impacts, and to present this information to the general public at local schools and organizations. The group was organized with the primary goal of teaching undergraduate students about effective ways to communicate basic climate science to nonscientists, but to also improve public understanding of anthropogenic climate change while starting a conversation among young people in the community. We will identify lessons learned after one year, discuss effective strategies, and summarize student feedback.

  13. Improved Sparse Channel Estimation for Cooperative Communication Systems

    2012-01-01

    Full Text Available Accurate channel state information (CSI is necessary at receiver for coherent detection in amplify-and-forward (AF cooperative communication systems. To estimate the channel, traditional methods, that is, least squares (LS and least absolute shrinkage and selection operator (LASSO, are based on assumptions of either dense channel or global sparse channel. However, LS-based linear method neglects the inherent sparse structure information while LASSO-based sparse channel method cannot take full advantage of the prior information. Based on the partial sparse assumption of the cooperative channel model, we propose an improved channel estimation method with partial sparse constraint. At first, by using sparse decomposition theory, channel estimation is formulated as a compressive sensing problem. Secondly, the cooperative channel is reconstructed by LASSO with partial sparse constraint. Finally, numerical simulations are carried out to confirm the superiority of proposed methods over global sparse channel estimation methods.

    Full Text Available The article deals with the problem of developing listening skills for improving foreign language communicative competence. The practical value of using an authentic foreign language text at a foreign language lesson is determined. The ways of the use of the English language recordings in the educational process of students are outlined. It is found out that tracks with foreign information should be used only in the certain methodical situations. Multimedia helps effectively a teacher to achieve outlined objectives of improving foreign language communicative competence for multiple repetition of a speech model for making permanent listening item of language units. The basic stages of work with foreign language recordings are determined: teaching a foreign language listening (teaching to listen and understand the foreign language track means to overcome the methodological difficulties that require a certain amount of time and special training. This is explained by the fact that there are lots of difficulties on the way of understanding a foreign language: an unusual speed of speech, presence of unknown vocabulary, specific rhythms and melody; teaching a foreign language speech with the special models pronounced by foreign speakers (teaching students to practical mastery of a foreign language is intrinsically linked with involvement into the educational process of original English tracks, those are made by highly skilled experts (foreign speakers; learning a new vocabulary due to a dialogue, an extract of a play or a conversation, songs, prose and poetry (it is noted that the students’ interest of learning foreign language songs and poems is extremely high, and it primarily promotes strong learning; analysing the recorded students’ speech (fixing student’s speech and analysing their mistakes is very important at any stage of learning a foreign language for self-control and self-correction.

  15. The hazard communication of fragrance allergens must be improved.

    2013-07-01

    Contact allergy is a global health problem that could be alleviated considerably if the general public could reduce contact to sensitizers. Efficient hazard communication would be a valuable instrument to achieve this. What do current regulations concerning fragrance sensitizers in cosmetic products in Europe contribute? For example, there are bans and restrictions according to the Cosmetic Regulation, there is the "26 allergens rule" that requires that the names of some allergenic fragrance ingredients are listed on the containers, there is labeling and classification of hazardous products according to Regulation 1272/2008, and there is the regulation concerning the registration, evaluation, authorization and restriction of chemicals (REACH). Do these regulations increase consumer protection by suitable hazard communication instruments? Four main problems were identified. First, according to the 26 allergens rule, consumers carry a very large part of the responsibility for risk reduction management. They need to be capable and motivated to recognize the names of strong allergens listed in the ingredient list and decide for themselves whether they want to run the risk or not, provided that they are aware of their responsibility. Second, cosmetic products do not need to be classified and labeled like other consumer goods, according to the European Commission Regulation 1272/2008, if they contain hazardous substances. Third, some pictograms for hazardous substances, for example, the exclamation mark for sensitizers, are not well understood by the majority of the general public. Fourth, very often, the design of cosmetic containers implies health and well being, even if the respective products contain sensitizers or other hazardous substances. Against this background, the following improvements are proposed: 1) the 26 allergens rule needs revision, 2) the exception for cosmetic products from labeling and classification should be abolished, 3) a new self

    2015-01-01

    Although many pediatric intensive care units (PICUs) use beside communication sheets (BCSs) to highlight daily goals, the optimal format is unknown. A site-specific BCS could improve both PICU communication and compliance completing the BCS. Via written survey, PICU staff at an academic children's hospital provided recommendations for improving and revising an existing BCS. Pre- and post-BCS revision, PICU staff were polled regarding PICU communication and BCS effectiveness, and daily compliance for completing the BCS was monitored. After implementation of the revised BCS, staff reporting "excellent" or "very good" day-to-day communication within the PICU increased from 57% to 77% (P = .02). Compliance for completing the BCS also increased significantly (75% vs 83%, P = .03). Introduction of a focused and concise BCS tailored to a specific PICU leads to improved perceptions of communication by PICU staff and increased compliance completing the daily BCS. © The Author(s) 2014.

    The prediction performances of several climatological models, including the ionospheric conductivity and electron density model, RADAR C, and Ionospheric Communications Analysis and Predictions Program, are evaluated for different regions and sunspot number inputs. Particular attention is given to the near-real-time (NRT) predictions associated with single-station updates. It is shown that a dramatic improvement can be obtained by using single-station ionospheric data to update the driving parameters for an ionospheric model for NRT predictions of f(0)F2 and other ionospheric and HF circuit parameters. For middle latitudes, the improvement extends out thousands of kilometers from the update point to points of comparable corrected geomagnetic latitude. 10 refs

    Concern over the frequency of unintended harm to patients has focused attention on the importance of teamwork and communication in avoiding errors. This has led to experiments with teamwork training programmes for clinical staff, mostly based on aviation models. These are widely assumed to be effective in improving patient safety, but the extent to which this assumption is justified by evidence remains unclear. A systematic literature review on the effects of teamwork training for clinical staff was performed. Information was sought on outcomes including staff attitudes, teamwork skills, technical performance, efficiency and clinical outcomes. Of 1036 relevant abstracts identified, 14 articles were analysed in detail: four randomized trials and ten non-randomized studies. Overall study quality was poor, with particular problems over blinding, subjective measures and Hawthorne effects. Few studies reported on every outcome category. Most reported improved staff attitudes, and six of eight reported significantly better teamwork after training. Five of eight studies reported improved technical performance, improved efficiency or reduced errors. Three studies reported evidence of clinical benefit, but this was modest or of borderline significance in each case. Studies with a stronger intervention were more likely to report benefits than those providing less training. None of the randomized trials found evidence of technical or clinical benefit. The evidence for technical or clinical benefit from teamwork training in medicine is weak. There is some evidence of benefit from studies with more intensive training programmes, but better quality research and cost-benefit analysis are needed.

  1. A communication strategy to improve nutrition in Indonesia.

    Griffiths, M; Nobbe, E

    1985-01-01

    As an experimental project, the Nutrition Communication and Behavior Change Component (NCBC) of the Indonesian Nutrition Development Program (UPGK) showed how social marketing could further the national program's goal of significantly improving the nutrition of Indonesia's young children and pregnant and nursing women. The social marketing approach successfully developed nutrition communication materials that were responsive to the needs, desires, and resources of the communities, particularly of the mothers and volunteer nutrition workers. Between 1977-79 Dr. I.B. Mantra, NCBC Director, established administrative and community infrastructures modeled after UPGK in 5 culturally diverse areas in Indonesia. In mid-1979, with technical assistance from Manoff International, the project departed from the approach of the national plan and embarked upon an unprecedented course with the formative evaluation of educational messages and a communication strategy. The success of the NCBC Component was to be judged by whether education -- as the sole intervention -- could produce significant improvements in the nutritional status of children and the improved nutrient intake of pregnant and lactating women in project communities. The 1st step was to design and execute qualitative research on the health and nutritional problems of children under 3 and pregnant and nursing women, consisting of in-depth household interviews, concept testing with mothers, and focus group interviews with kaders and community opinion leaders. Surveying was based on issues identified earlier by the Ministry of Health as most severe for the population overall. The qualitative investigation identified the need for change or reinforcement in particular nutrition-related behaviors. The target audience of mothers was segmented according to their needs during designated maternal stages and by the age-related dietary needs of their children under 3 years of age. This meant that only the most useful

    Despite being among the best academically prepared of the country, many medical students have difficulties to communicate in writing. In 2005, the School of Medicine at the Pontificia Universidad Católica de Chile introduced a writing workshop in the undergraduate curriculum, to enhance the students' writing skills. To describe the workshop and its impact on the writing skills of 3 cohorts of students. This 30-h workshop used a participative methodology with emphasis on deliberate practice and feedback. Students worked in small groups with a faculty member specially trained in writing. The qualities of the essays written before and after the workshop were compared. Essays were rated by a professional team that used an analytic rubric to measure formal aspects of text writing as well as more complex thinking processes. There was a significant improvement in the quality of the texts written after the workshop; the main changes occurred in argumentation, and in paragraph and text structure. This improvement was inversely proportional to the initial level of performance, and independent of gender. A writing workshop based on deliberate practice and personalized feedback is effective to enhance the writing proficiency of medical students. Due to its design, this workshop could be useful for students of other careers and universities.

    There is increasing pressure for neuroscientists to communicate their research and the societal implications of their findings to the public. Communicating science is challenging and the transformation of communication by digital and interactive media makes the challenge even greater. To successfully facilitate dialogue with the public in this new media landscape we suggest three courses of action for the neuroscience community: a cultural shift that explicitly recognizes and rewards public outreach, the identification and development of neuroscience communication experts, and ongoing empirical research on public communication of neuroscience.

    The long-lived 176Lu-176Hf and 147Sm-143Nd radioisotope systems are commonly used chronometers, but when applied to meteorites, they can reveal disturbances. Specifically, Lu-Hf isochrons commonly yield dates up to ∼300 Myr older than the solar system and varying initial 176Hf/177Hf values. We investigated this problem by attempting to construct mineral and whole rock isochrons for eucrites and angrites. Meteorites from different parent bodies exhibit similar disturbance features suggesting that a common process is responsible. Minerals scatter away from isochron regressions for both meteorite classes, with low-Hf phases such as plagioclase and olivine typically being most displaced above (or left of) reference isochrons. Relatively Hf-rich pyroxene is less disturbed but still to the point of steepening Lu-Hf errorchrons. Using our Lu-Hf and Sm-Nd data, we tested various Hf and Lu redistribution scenarios and found that decoupling of Lu/Hf from 176Hf/177Hf must postdate the accumulation of significant radiogenic 176Hf. Therefore early irradiation or diffusion cannot explain the excess 176Hf. Instead, disturbed meteorite isochrons are more likely caused by terrestrial weathering, contamination, or common laboratory procedures. The partial dissolution of phosphate minerals may predominantly remove rare earth elements including Lu, leaving relatively immobile and radiogenic Hf behind. Robust Lu-Hf (and improved Sm-Nd) meteorite geochronology will require the development of chemical or physical methods for removing unsupported radiogenic Hf and silicate-hosted terrestrial contaminants without disturbing parent-daughter ratios.

  5. Communicating about nuclear events: Some suggestions to improve INES

    International Nuclear Information System (INIS)

    Kermisch, Céline; Labeau, Pierre-Etienne

    2013-01-01

    This paper provides a critical analysis of the International Nuclear and Radiological Event Scale (INES) and its use, both from an epistemic and an ethical perspective. As very few papers have been dedicated to this subject, our critical analysis is mainly based on the INES 2009 User's Manual and on technical information issued by different nuclear agencies. Our critical analysis leads to suggest several elements, which could contribute to the improvement of the INES scale and thereby to a better communication about nuclear events. First, we show that multiple criteria are used to assign an INES rating, which could lead to an insufficient differentiation between events. In order to avoid this issue, we suggest to clarify the criteria that are used to assess the level of the event. Then, we show that level 7 of the INES scale is ill-defined as it does not allow to properly take differences in severity between disasters into account. In this regard, we recommend to use an open scale instead. Moreover, we highlight the fact that INES is able to take into account neither events with long-term evolution nor events involving multiple initiators. In this respect, we suggest providing additional guidelines and reflecting about the data on which to rely, in order to assess an INES level. Furthermore, we reflect on who should be rating a nuclear event and we recommend that, for severe events, an independent and plural agency should be in charge. Finally, we show why INES appears to be insufficient for a global communication, and we suggest to complement the INES rating with additional information in parallel. -- Highlights: •We provide a critical analysis of the INES scale and suggestions to improve it. •The rating criteria should be clarified to allow differentiation between events. •An open scale should be used to differentiate between level-7 accidents. •Additional guidelines should be provided for complex and evolving events. •We provide suggestions to satisfy

    Summoning is a key component of communication between obstetrics and neonatal resuscitation team (NRT) in advance of deliveries. A paging system is a commonly used summoning tool. The timeliness and information contained in the page help NRT to optimally prepare for postdelivery infant care. Our aim was to increase the frequency that summoning pages contained gestational age and reason for NRT attendance to >90%. At baseline, 8% of pages contained gestational age and 33% of pages contained a reason for NRT attendance. Sequential Plan-Do-Study-Act cycles were used as our model for quality improvement. During the 8-month improvement period, the per cent of pages increased to 97% for gestational age and 97% for reason for NRT attendance. Measures of page timeliness, our balancing measure, did not change. Summoning communication between obstetric and NRT is crucial for optimal perinatal outcomes. The active involvement of all stakeholders throughout the project resulted in the development of a standardised paging tool and a more informative paging process, which is a key communication tool used in many centres.

    The HF laser is an attractive candidate driver for a large-system ICF scientific demonstration facility, for an ICF experimental power reactor and for a commercial laser--fusion power reactor. Previous accomplishments of the program have included demonstrations of high efficiency and high energy capability, efficient energy extraction from HF amplifiers, good beam quality and focusability, and short-pulse generation and amplification. In the reporting period, beam quality has been determined to be near-diffraction limited for a short pulsewidth (6 ns to 25 ns) oscillator-amplifier chain, suppression of amplified spontaneous emission has been demonstrated on an individual spectral line, high-pressure characteristics have been determined for the Phoenix I amplifier, and detailed comparisions between the kinetic code and experiments have been made. Details of two major upcoming experiments are also included. The first is energy extraction and beam quality measurements on the Phoenix I amplifier operating under saturated output power conditions. The second experiment, using a newly designed amplifier (Phoenix II), is designed to demonstrate the concept of angular-multiplexing: a pulse width-compression scheme

    We report the results of experimentally investigated dependences of temporal, spectral and spatial characteristics of an inductive HF-laser generation on the pump conditions. Gas mixtures H{sub 2} – F{sub 2}(NF{sub 3} or SF6{sub 6}) and He(Ne) – H{sub 2} – F{sub 2}(NF{sub 3} or SF{sub 6}) were used as active media. The FWHM pulse duration reached 0.42 μs. This value corresponded to a pulsed power of 45 kW. For the first time, the emission spectrum of an inductive HF laser was investigated, which consisted of seven groups of bands with centres around the wavelengths of 2732, 2736, 2739, 2835, 2837, 2893 and 2913 nm. The cross section profile of the laser beam was a ring with a diameter of about 20 mm and width of about 5 mm. Parameters of laser operation in the repetitively pulsed regime were sufficiently stable. The amplitude instability of light pulses was no greater than 5% – 6%. (lasers)

    To explore hospital leaders' perceptions of organisational factors as barriers and/or facilitators in improving inpatient-outpatient (IP-OP) communication. Semistructured in-person interviews. Constant comparative method of qualitative data. Inpatient psychiatry units in 33 general medical/surgical and specialty psychiatric hospitals in California and Massachusetts (USA). Psychiatry chair/chief, service director or medical director. Importance to leadership, resources, organisational structure and culture. A majority of hospital leaders rated the IP-OP communication objective as highly or moderately important. Hospitals with good IP-OP communication had structures in place to support communication or had changed/implemented new procedures to enhance communication, and anticipated clinicians would 'buy in' to the goal of improved communication. Hospitals reporting no improvement efforts were less likely to have structures supporting IP-OP communication, anticipated resistance among clinicians and reported a need for technological resources such as electronic health records, integrated IT and secure online communication. Most leaders reported a need for additional staff time and information, knowledge or data. For many hospitals, successfully improving communication will require overcoming organisational barriers such as cultures not conducive to change and lack of resources and infrastructure. Creating a culture that values communication at discharge may help improve outcomes following hospitalisation, but changes in healthcare delivery in the past few decades may necessitate new strategies or changes at the systems level to address barriers to effective communication.

    Full Text Available BACKGROUND: In the context of interacting activities requiring close-body contact such as fighting or dancing, the actions of one agent can be used to predict the actions of the second agent. In the present study, we investigated whether interpersonal predictive coding extends to interactive activities--such as communicative interactions--in which no physical contingency is implied between the movements of the interacting individuals. METHODOLOGY/PRINCIPAL FINDINGS: Participants observed point-light displays of two agents (A and B performing separate actions. In the communicative condition, the action performed by agent B responded to a communicative gesture performed by agent A. In the individual condition, agent A's communicative action was substituted with a non-communicative action. Using a simultaneous masking detection task, we demonstrate that observing the communicative gesture performed by agent A enhanced visual discrimination of agent B. CONCLUSIONS/SIGNIFICANCE: Our finding complements and extends previous evidence for interpersonal predictive coding, suggesting that the communicative gestures of one agent can serve as a predictor for the expected actions of the respondent, even if no physical contact between agents is implied.

    Effective communication is needed for optimal cancer pain management. This study assessed the efficacy of a general communication skills training program for oncology nurses on communication about pain management. A total of 115 nurses were randomly assigned to a training group (TG) or control group (CG). The assessment included the recording of interviews with a simulated cancer patient at baseline for both groups and after training (TG) or 3 months after baseline (CG). Two psychologists rated the content of interview transcripts to assess cancer pain management communication. Group-by-time effects were measured using a generalized estimating equation. Trained nurses asked the simulated patient more questions about emotions associated with pain (relative rate [RR] = 4.28, p = 0.049) and cognitions associated with pain treatment (RR = 3.23, p management (RR = 0.40, p = 0.006) compared with untrained nurses. The general communication skills training program improved only a few of the communication strategies needed for optimal cancer pain management in nursing. General communication skills training programs should be consolidated using specific modules focusing on communication skills related to cancer pain management.

    This paper describes how design science theory and methods and use of artificial intelligence (AI) components can improve the effectiveness of health communication. We identified key weaknesses of traditional health communication and features of more successful eHealth/AI communication. We examined characteristics of the design science paradigm and the value of its user-centered methods to develop eHealth/AI communication. We analyzed a case example of the participatory design of AI components in the ChronologyMD project intended to improve management of Crohn's disease. eHealth/AI communication created with user-centered design shows improved relevance to users' needs for personalized, timely and interactive communication and is associated with better health outcomes than traditional approaches. Participatory design was essential to develop ChronologyMD system architecture and software applications that benefitted patients. AI components can greatly improve eHealth/AI communication, if designed with the intended audiences. Design science theory and its iterative, participatory methods linked with traditional health communication theory and methods can create effective AI health communication. eHealth/AI communication researchers, developers and practitioners can benefit from a holistic approach that draws from theory and methods in both design sciences and also human and social sciences to create successful AI health communication.

    This study was conducted to explore the effects of an event history calendar (EHC) approach on adolescent sexual risk communication and sexual activity. Adolescent school-linked health clinic patients (n = 30) who reported sexual activity self-administered the EHC that was used by nurse practitioners (NPs; n = 2) during a clinic visit. Immediately pre- and post-visit, and at 1 and 3 months, adolescents reported sexual risk behaviors and perceptions about EHC communication on questionnaires and by interview. NPs reported their perceptions of EHCs by questionnaire after the visit and poststudy interview. The EHC approach facilitated communication and adolescent awareness of their risk behaviors. Scores increased on Amount of Communication, t(29) = 8.174, p Communication, t(29) = 3.112, p = .004; Client Involvement in Decision Making, t(29) = 3.901, p = .001, and Client Satisfaction with Interpersonal Style, t(29) = 3.763, p = .001. Adolescents reported decreased sexual intercourse at 1 month, p = .031. School nurses could use the EHC approach to facilitate adolescent communication and tailoring of interventions.

    Many physicians struggle to communicate with patients with chronic, non-malignant pain (CNMP). Through the use of a Web module, the authors aimed to improve faculty participants' communication skills knowledge and confidence, use of skills in clinical practice, and actual communication skills. The module was implemented for faculty development among clinician-educators with university faculty appointments, outpatient clinical practices, and teaching roles. Participants completed the Collaborative Opioid Prescribing Education Risk Evaluation and Mitigation Strategy (COPE-REMS®) module, a free Web module designed to improve provider communication around opioid prescribing. Main study outcomes were improvements in CNMP communication knowledge, attitudes, and skills. Skills were assessed by comparing a subset of participants' Observed Structured Clinical Exam (OSCE) performance before and after the curriculum. Sixty-two percent of eligible participants completed the curriculum in 2013. Knowledge-based test scores improved with curriculum completion (75% vs. 90%; P communication skills on the OSCE improved after the curriculum (mean 67% vs. 79%, P = 0.03). Experienced clinician-educators improved their communication knowledge, attitudes, and skills in managing patients with CNMP after implementation of this curriculum. The improvements in attitudes were sustained at six months. A Web-based curriculum such as COPE-REMS® may be useful for other programs seeking improvement in faculty communication with patients who have CNMP. © 2016 American Academy of Pain Medicine.

    2018-01-01

    Full Text Available Computer-supported collaborative learning facilitates the extension of second language acquisition into social practice. Studies on its achievement effects speak directly to the pedagogical notion of treating communicative practice in synchronous computer-mediated communication (SCMC: real-time communication that takes place between human beings via the instrumentality of computers in forms of text, audio and video communication, such as live chat and chatrooms as socially-oriented meaning construction. This review begins by considering the adoption of social interactionist views to identify key paradigms and supportive principles of computer-supported collaborative learning. A special focus on two components of communicative competence is then presented to explore interactional variables in synchronous computer-mediated communication along with a review of research. There follows a discussion on a synthesis of interactional variables in negotiated interaction and co-construction of knowledge from psycholinguistic and social cohesion perspectives. This review reveals both possibilities and disparities of language socialization in promoting intersubjective learning and diversifying the salient use of interactively creative language in computer-supported collaborative learning environments in service of communicative competence.

    2015-11-01

    Thousands of people die annually in hospitals because of poor communication and teamwork between health care team members. Standardized tools and strategies help increase the amount and quality of communication. Two structured communication methods include implementing huddles and the use of the situation, background, assessment, and recommendation (SBAR) communication framework. To improve communication among nurse practitioners and registered nurses within a pediatric emergency department, a performance-improvement project with the structured processes of a joint patient evaluation and huddle was implemented. Data were gathered from 32 nurses and 2 nurse practitioners using structured observation and pre- and post-implementation surveys. The following outcomes were measured: presence or absence of joint patient evaluation and SBAR-guided huddle, verbalization of treatment plan, communication, teamwork, and nurse satisfaction. Eighty-three percent of patient encounters included a joint evaluation. A huddle structured with SBAR was conducted 86% of the time. Registered nurses and nurse practitioners verbalized patients' treatment plans in 89% of cases and 97% of cases, respectively. Improved teamwork, communication, and nursing satisfaction scores were demonstrated among the nurse practitioners and registered nurses. This project showed the feasibility of a simple and inexpensive joint nurse practitioner-registered nurse patient evaluation followed by a structured huddle, which improved communication, teamwork, and nurse satisfaction scores. This performance-improvement project has the potential to enhance efficiency by reducing redundancy, as well as to improve patient safety through the use of structured communication techniques.

    Effective interdisciplinary communication is important to achieve better quality in health care. The aims of this study were to compare conventional and complementary providers' experience of communication about complementary therapies and conventional medicine with their cancer patients, and to investigate how they experience interdisciplinary communication and cooperation. This study analyzed data from a self-administrated questionnaire. A total of 606 different health care providers, from four counties in Norway, completed the questionnaire. The survey was developed to describe aspects of the communication pattern among oncology doctors, nurses, family physicians and complementary therapists (acupuncturists, massage therapists and reflexologists/zone-therapists). Between-group differences were analyzed using chi-square, ANOVA and Fisher's exact tests. Significance level was defined as p communication with their cancer patients regarding complementary therapies. While complementary therapists advised their patients to apply both complementary and conventional modalities, medical doctors were less supportive of their patients' use of complementary therapies. Of conventional providers, nurses expressed more positive attitudes toward complementary therapies. Opportunities to improve communication between conventional and complementary providers were most strongly supported by complementary providers and nurses; medical doctors were less supportive of such attempts. A number of doctors showed lack of respect for complementary therapists, but asked for more research, guidelines for complementary modalities and training in conventional medicine for complementary therapists. For better quality of care, greater communication about complementary therapy use is needed between cancer patients and their conventional and complementary providers. In addition, more communication between conventional and complementary providers is needed. Nurses may have a crucial role in

    Failure to successfully communicate maintenance activities, abnormal conditions, emergency response procedures, process hazards, and hundreds of other items of critical information can lead to disaster, regardless of the thoroughness of the process safety management system. Therefore, a well-functioning process safety program depends on maintaining successful communication interfaces between each involved employee or stakeholder and the many other employees or stakeholders that person must interact with. The authors discuss a process to identify the critical 'Interfaces' between the many participants in a process safety management system, and then to establish a protocol for each critical interface

    To pilot an evidence-based communication skills model (SAGE & THYME) with UK District Nurses (DNs) who visit patients with advanced cancer early in the dying trajectory. Evidence suggests that DNs lack confidence in communication skills and in assessing cancer patients' psycho-social needs; also that they lack time. SAGE & THYME is a highly structured model for teaching patient centred interactions. It addresses concerns about confidence and time. Mixed methods. 33 DNs were trained in SAGE & THYME in a three hour workshop and interviewed in focus groups on three occasions: pre-training, immediately post-training and two months post-training. Questionnaires measuring perceived outcomes of communication, confidence in communication and motivation to use SAGE & THYME were administered at the focus groups. SAGE & THYME provided a structure for conversations and facilitated opening and closing of interactions. The main principle of patient centeredness was reportedly used by all. Knowledge about communication behaviours helpful to patients improved and was sustained two months after training. Increased confidence in communication skills was also sustained. Motivation to use SAGE & THYME was high and remained so at two months, and some said the model saved them time. Challenges with using the model included controlling the home environment and a change in style of communication which was so marked some DNs preferred to use it with new patients. Training DNs in SAGE & THYME in a three hour workshop appears to be a promising model for improving communication skills when working with cancer patients. Crown Copyright © 2015.

    Inadequate communication between medical teams and families can lead to errors and poor-quality care. The objective was to understand why communication between the clinical team and families was not occurring consistently in the pediatric intensive care unit and improve the system using a multidisciplinary improvement team including a family advisor. This improvement project used Lean Six Sigma. The team observed updates and collected documented communication, survey, interview, and focus group data from families and staff. Root causes of failures included lack of assigned responsibility, lack of defined daily update, and lack of a daily communication standard. Process changes were implemented, resulting in an increased mean documented communication rate from 13% pre intervention to 65% post intervention that was sustained for more than 2 years (P < .001). Including a family advisor as an equal member of an improvement team provides family empowerment and a greater chance of success in complex areas. © The Author(s) 2015.

  10. How do Australian Small and Medium Enterprises Communicate their Environmental Improvement Activities Online?

    Directory of Open Access Journals (Sweden)

    Craig Parker

    2011-03-01

    Full Text Available There have been calls in the IS/eBusiness literature for research on "green" IS/IT in a Small and Medium Enterprises (SMEs context. The Corporate Social Responsibility (CSR literature has neglected the issue of how SMEs can use websites to communicate their environmental improvement activities. This paper links these two previously separate disciplines by reporting on a content analysis of 443 Australian SME websites from four industry sectors to identify if and how they use websites to communicate their environmental improvement activities. The study found that 47 websites were communicating such activities in some form. A detailed analysis was undertaken of these 47 websites to identify emergent themes relating to how these SMEs were communicating their environmental improvement activities. These themes resulted in a reconceptualisation of the traditional "4 Ps" of marketing for online communication of environmental improvement activities by SMEs: profile; product; process and prominence.

    Communication problems impede effective symptom management during chemotherapy. The primary aim of this pilot randomized controlled trial was to test the effects of a personal digital assistant-delivered communication intervention on pain, depression, and fatigue symptoms among breast cancer patients undergoing chemotherapy. Secondary aims included assessment of 1) study feasibility, 2) patient and clinician responses to study participation, and 3) intervention effects on health-related quality of life (HRQoL) and communication self-efficacy. Intervention group participants (n = 27) completed symptom inventories at baseline, once per week during treatment, and at posttreatment. Depending on symptom severity, they viewed race-concordant videos on how to communicate about pain, depression and/or fatigue, using the personal digital assistant. Symptom records were tracked and shared with clinicians. Control group participants (n = 23) received usual care. Longitudinal random effects modeling assessed the changes in average symptom scores over time. Descriptive statistics assessed study feasibility and intervention effects on HRQoL and communication self-efficacy. Postintervention focus groups, interviews, and surveys assessed responses to study participation. Mean age of the participants was 51.0 years; 42 participants (84%) were white. In comparison with control, intervention group participants reported lower average pain severity over time (P = .015). Mean pain interference scores over time were marginally different between groups (P = .07); mean depression and fatigue scores over time were statistically nonsignificant. Feasibility outcomes and perspectives about study participation were positive. Mean pre-post decreases in HRQoL were generally higher among intervention group participants; pre-post changes in communication self-efficacy were equivalent. Mixed findings of the study indicate the need for future research.

  14. On eliminating synchronous communication in molecular simulations to improve scalability

    Science.gov (United States)

    Straatsma, T. P.; Chavarría-Miranda, Daniel G.

    2013-12-01

    Molecular dynamics simulation, as a complementary tool to experimentation, has become an important methodology for the understanding and design of molecular systems as it provides access to properties that are difficult, impossible or prohibitively expensive to obtain experimentally. Many of the available software packages have been parallelized to take advantage of modern massively concurrent processing resources. The challenge in achieving parallel efficiency is commonly attributed to the fact that molecular dynamics algorithms are communication intensive. This paper illustrates how an appropriately chosen data distribution and asynchronous one-sided communication approach can be used to effectively deal with the data movement within the Global Arrays/ARMCI programming model framework. A new put_notify capability is presented here, allowing the implementation of the molecular dynamics algorithm without any explicit global or local synchronization or global data reduction operations. In addition, this push-data model is shown to very effectively allow hiding data communication behind computation. Rather than data movement or explicit global reductions, the implicit synchronization of the algorithm becomes the primary challenge for scalability. Without any explicit synchronous operations, the scalability of molecular simulations is shown to depend only on the ability to evenly balance computational load.

    Bishop, Tara F; Press, Matthew J; Mendelsohn, Jayme L; Casalino, Lawrence P

    2013-08-01

    Because electronic communication is quick, convenient, and inexpensive for most patients, care that is truly patient centered should promote the use of such communication between patients and providers, even using it as a substitute for office visits when clinically appropriate. Despite the potential benefits of electronic communication, fewer than 7 percent of providers used it in 2008. To learn from the experiences of providers that have widely incorporated electronic communication into patient care, we interviewed leaders of twenty-one medical groups that use it extensively with patients. We also interviewed staff in six of those groups. Electronic communication was widely perceived to be a safe, effective, and efficient means of communication that improves patient satisfaction and saves patients time but that increases the volume of physician work unless office visits are reduced. Practice redesign and new payment methods are likely necessary for electronic communication to be more widely used in patient care.

    Full Text Available Communication may be considered an important management tool. Internal communication is notan invention in management, but a basic need. Informing people - or even better, involving them – it is notonly in the employees’ best interest. The Company may take advantage of this state of affairs in several ways:informed employees know what they do, and especially why. They understand the company’s objectives andhow they can achieve them more effectively. A good working environment is in the best interest of everyresponsible employer, for that is a source of increased efficiency. Informed employees are generally morecontent with their professional status; they have a contextualized sense of their personal and professionalvalue and they show more responsibility. Their personal orientation is much better aligned with the companyand it may contribute significantly to achieving its business objectives. To inform people is a good thing, butto involve them it is even better. Involvement is the living proof of the difference between a good employerand a great one. This information can help in attracting good quality staff and it creates support fromemployees in terms of recruitment and sales, it generates passion, satisfaction at work and it reduces theabsenteeism; it provides opportunities for personal growth and development, it creates a sense of communityand an open and honest organizational culture.

    2007-12-01

    A broadband probe-fed microstrip antenna with E-shaped patch on a single-layer air substrate is investigated. Bandwidth enhancement of the antenna is achieved by inserting two parallel slots into its radiating patch. The effects of the antenna parameters are analyzed, and their optimal values for broadband operation are obtained. The design parameters are formulated as a function of the center frequency, and the empirical equations are validated by simulation. A 51.5% enhanced E patch antenna for modern wireless communications (Personal Communications Service, Digital Cellular System, Universal Mobile Telecommunications System, Wireless Local Area Network 802.11 b/g, and Bluetooth) is designed, simulated, fabricated, and measured. A comparison between simulated and measured results is presented, and it showed satisfactory agreement. Moreover, the effect of incorporating more parallel slots into the radiating patch is investigated. The antenna is designed and simulated for different scenarios (four slots, six slots, and eight slots), where a bandwidth of 57% is achieved in the eight-slot design.

    2009-01-01

    In the last years new type Cu-Hf-Al ternary alloys were developed with high glass forming ability and ductility. The addition of Al to Cu-Hf alloys results in improvements in glass formation, thermal stability and mechanical properties of these alloys. We have investigated new Cu-based bulk amorphous alloys in Cu-Hf-Al ternary system. The alloys with Cu 49 Hf 42 Al 9 , Cu 46 Hf 45 Al 9 , Cu 50 Hf 42.5 Al 7.5 and Cu 50 Hf 45 Al 5 compositions were prepared by arc melting. The samples were made by centrifugal casting and were investigated by X-ray diffraction method. Thermodynamic properties were examined by differential scanning calorimetry and the structure of the crystallising phases by scanning electron microscopy. The determination of liquidus temperatures of alloys were measured by differential thermal analysis.

  9. Improving a Power Line Communications Standard with LDPC Codes

    Hsu Christine

    2007-01-01

    Full Text Available We investigate a power line communications (PLC scheme that could be used to enhance the HomePlug 1.0 standard, specifically its ROBO mode which provides modest throughput for the worst case PLC channel. The scheme is based on using a low-density parity-check (LDPC code, in lieu of the concatenated Reed-Solomon and convolutional codes in ROBO mode. The PLC channel is modeled with multipath fading and Middleton's class A noise. Clipping is introduced to mitigate the effect of impulsive noise. A simple and effective method is devised to estimate the variance of the clipped noise for LDPC decoding. Simulation results show that the proposed scheme outperforms the HomePlug 1.0 ROBO mode and has lower computational complexity. The proposed scheme also dispenses with the repetition of information bits in ROBO mode to gain time diversity, resulting in 4-fold increase in physical layer throughput.

    2017-11-01

    To pilot a brief individualized feedback intervention to improve the communication skills of parents with an adolescent with type 1 diabetes. Parent-adolescent dyads (N = 79) discussed a diabetes-related problem, while an interventionist rated the parent's communication skills to give feedback to the parents. Parents were then randomized to a brief feedback session to target person-centered communication skills or an educational session. Dyads discussed another diabetes care problem to assess for change in communication skills. Independent raters coded parent communication skills from video recordings to rate behaviors in the service of examining possible changes in communication skills. Dyads completed ratings of perceived closeness and empathy after each conversation. Controlling for overall positive communication at baseline, parents who received feedback showed more improvement in specific person-centered communication skills than parents in the control group. Adolescents in the feedback group reported greater increases in parental empathy and intimacy from pre- to postmanipulation than the control. The feedback intervention showed preliminary efficacy for increasing person-centered communication skills and perceived empathy and intimacy. © The Author 2017.

    2017-04-01

    Professional communication skills have a significant impact on dental patient satisfaction and health outcomes. Communication skills training has been shown to improve the communication skills of dental students. Therefore, strengthening communication skills training in dental education shows promise for improving dental patient satisfaction and outcomes. The aim of this study was to facilitate the development of dental communication skills training through a scoping review with compilation of a list of considerations, design of an example curriculum, and consideration of barriers and facilitators to adoption of such training. A search to identify studies of communication skills training interventions and programs was conducted. Search queries were run in three databases using both text strings and controlled terms (MeSH), yielding 1,833 unique articles. Of these, 35 were full-text reviewed, and 17 were included in the final synthesis. Considerations presented in the articles were compiled into 15 considerations. These considerations were grouped into four themes: the value of communication skills training, the role of instructors, the importance of accounting for diversity, and the structure of communication skills training. An example curriculum reflective of these considerations is presented, and consideration of potential barriers and facilitators to implementation are discussed. Application and evaluation of these considerations are recommended in order to support and inform future communication skills training development.

    Communication between physicians and patients is particularly challenging when patients do not speak the local language (in Switzerland, they are known as allophones). To assess the effectiveness of an intervention to improve communication skills of physicians who deal with allophone patients. 'Before-and-after' intervention study, in which both patients (allophone and francophone) and physicians completed visit-specific questionnaires assessing the quality of communication. Two consecutive samples of patients attending the medical outpatient clinic of a teaching hospital in French-speaking Switzerland. The intervention consisted of training physicians in communicating with allophone patients and working with interpreters. French-speaking patients served as the control group. The outcomes measured were: patient satisfaction with care received and with communication during consultation; and provider (primary care physician) satisfaction with care provided and communication during consultation. At baseline, mean scores of patients' assessments of communication were lower for allophone than for francophone patients. At follow-up, five out of six of the scores of allophone patients showed small increases (P French-speaking patients: explanations given by physician; respectfulness of physician; communication; overall process of the consultation; and information about future care. In contrast, physicians' assessments did not change significantly. Finally, after the intervention, the proportion of consultations with allophone patients in which professional interpreters were present increased significantly from 46% to 67%. The quality of communication as perceived by allophone patients can be improved with specific training aimed at primary care physicians.

    2018-03-01

    Rice University's bioengineering department incorporates written, oral, and visual communication instruction into its undergraduate curriculum to aid student learning and to prepare students to communicate their knowledge and discoveries precisely and persuasively. In a tissue culture lab course, we used a self- and peer-review tool called Calibrated Peer Review™ (CPR) to diagnose student learning gaps in visual communication skills on a poster assignment. We then designed an active learning intervention that required students to practice the visual communication skills that needed improvement and used CPR to measure the changes. After the intervention, we observed that students performed significantly better in their ability to develop high quality graphs and tables that represent experimental data. Based on these outcomes, we conclude that guided task practice, collaborative learning, and calibrated peer review can be used to improve engineering students' visual communication skills.

    2014-01-01

    The objectives of this study were to evaluate the effectiveness of Project CLEAR!, a novel simulation-based training program designed to instill Crew Resource Management (CRM) as the communication standard and to create a service-focused environment in the emergency department (ED) by standardizing the patient encounter. A survey-based study compared physicians' and nurses' perceptions of the quality of communication before and after the training program. Surveys were developed to measure ED staff perceptions of the quality of communication between staff members and with patients. Pretraining and posttraining survey results were compared. After the training program, survey scores improved significantly on questions that asked participants to rate the overall communication between staff members and between staff and patients. A simulation-based training program focusing on CRM and standardizing the patient encounter improves communication in the ED, both between staff members and between staff members and patients.

    Full Text Available Effective communication is the wish of every intelligent organization. In today’s society, modern communication means saved time, reduced costs, multiplied resources. Communication can be improved early in the development. Heredity of communication can be an excuse, a brake but also a mean of focus personal resources early in child development. To establish the link between communication and heredity was conducted a study at a nursery school in Sibiu. It have been questioned a number of 98 adults and 45 children, using questionnaires for the evaluation of social and communication skills, attention to detail and distributive, and tolerance to change, carried out by researchers from United Kingdom. Adults who have significant problems of communication, have children with communication problems. The results slightly above average obtained by some adults do not always correlate with slightly different results of the children. Another conclusion is that communication ability has a social and cultural coordinated. The correlations have been established between the responses of children and adults, but cannot identify precisely, slightly above average for the cases, which is the incidence of occurrence of communication problems.

  20. Does the inclusion of 'professional development' teaching improve medical students' communication skills?

    Science.gov (United States)

    2011-01-01

    Background This study investigated whether the introduction of professional development teaching in the first two years of a medical course improved students' observed communication skills with simulated patients. Students' observed communication skills were related to patient-centred attitudes, confidence in communicating with patients and performance in later clinical examinations. Methods Eighty-two medical students from two consecutive cohorts at a UK medical school completed two videoed consultations with a simulated patient: one at the beginning of year 1 and one at the end of year 2. Group 1 (n = 35) received a traditional pre-clinical curriculum. Group 2 (n = 47) received a curriculum that included communication skills training integrated into a 'professional development' vertical module. Videoed consultations were rated using the Evans Interview Rating Scale by communication skills tutors. A subset of 27% were double-coded. Inter-rater reliability is reported. Results Students who had received the professional development teaching achieved higher ratings for use of silence, not interrupting the patient, and keeping the discussion relevant compared to students receiving the traditional curriculum. Patient-centred attitudes were not related to observed communication. Students who were less nervous and felt they knew how to listen were rated as better communicators. Students receiving the traditional curriculum and who had been rated as better communicators when they entered medical school performed less well in the final year clinical examination. Conclusions Students receiving the professional development training showed significant improvements in certain communication skills, but students in both cohorts improved over time. The lack of a relationship between observed communication skills and patient-centred attitudes may be a reflection of students' inexperience in working with patients, resulting in 'patient-centredness' being an abstract concept

    ICT becomes a key element to improve industrial infrastructure efficiency and sustainable economic productivity. This study aims to analysis the impact of regional improvement on information and communication development in Indonesia. This research is a correlational study. Population of this research include 151 regions in Indonesia. By using a total sampling, there were 151 sample regions. The results show there are the strong impact of regional growth on increasing Gross Regional Domestic Product (GRDP) of information and communication. It can be seen from all regional improvement sub variables that have a high correlation in increasing GRDP of Information and Communication in Indonesia. Only two sub-variables that have low correlation to GRDP of Information and Communication variable i.e. GRDP of Agriculture, Forestry and Fishing (0.01) and GRDP of Mining and Quarrying (0.04). The correlation coefficient (R) is 0.981, means the variable of information and communication GRDP has a very strong correlation with regional growth variable. Thus the value of Adjusted R Square is 95.8%, means there are impact of regional growth variables in increasing GRDPof Information and Communication, while the increase of 4.2% of Information and Communication GRDP is influenced by other factors aside from regional improvement.

    HF-START (HF Simulator Targeting for All-users' Regional Telecommunications) is a user-friendly simulator developed to meet the needs of space weather users. Prediction of communications failure due to space weather disturbances is of high priority. Space weather users from various backgrounds with high economic impact, i.e. airlines, telecommunication companies, GPS-related companies, insurance companies, international amateur radio union, etc., recently increase. Space weather information provided by Space Weather Information Center of NICT is, however, too professional to be understood and effectively used by the users. To overcome this issue, I try to translate the research level data to the user level data based on users' needs and provide an immediate usable data. HF-START is positioned to be a space weather product out of laboratory based truly on users' needs. It is originally for radio waves in HF band (3-30 MHz) but higher frequencies up to L band are planned to be covered. Regional ionospheric data in Japan and southeast Asia are employed as a reflector of skywave mode propagation. GAIA (Ground-to-topside model of Atmosphere and Ionosphere for Aeronomy) model will be used as ionospheric input for global simulation. To evaluate HF-START, an evaluation campaign for Japan region will be launched in coming months. If the campaign successes, it will be expanded to southeast Asia region as well. The final goal of HF-START is to provide the near-realtime necessary radio parameters as well as the warning message of radio communications failure to the radio and space weather users.

    To improve physician/patient communication and familiarize surgeons with contemporary skills for and metrics assessing communication, courses were developed to provide academic general surgery residents and faculty with a toolkit of information, behaviors, and specific techniques. If academic faculty are expected to mentor residents in communication and residents are expected to learn good communication skills, then both should have the necessary education to accomplish such a goal. Didactic lectures introduced current concepts of physician-patient communication including information on better patient care, fewer malpractice suits, and the move toward transparency of communication metrics. Next, course participants viewed and critiqued "Surgi-Drama" videos, with actors simulating "before" and "after" physician-patient communication scenarios. Finally, participants were provided with a "toolkit" of techniques for improving physician-patient communication including "2-3-4"-a semiscripted short communication tool residents and other physicians can use in patient encounters-and a number of other acronymic approaches. Each participant was asked to complete an anonymous evaluation to assess course content satisfaction. Overall, 86% of residents participated (68/79), with a 52% response rate (35/68) for the evaluation tool. Overall, 88% of faculty participated (84/96), with an 84% response rate (71/84). Residents voiced satisfaction with all domains. For faculty, satisfaction was quantitatively confirmed (Likert score 4 or 5) in 4 of 7 domains, with the highest satisfaction in "communication of goals" and "understanding of the HCAHPS metric." The percentage of "top box" Doctor Communication Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores and national percentile ranking showed a sustained increase more than 1 and 2 years from the dates of the courses. The assessment of communication skills is increasing in importance in the practice of

    In HIV-infected individuals, impaired mitochondrial function may contribute to cardiometabolic disease as well as to fatigue and frailty. Aerobic exercise improves total body energy reserves; however, its impact at the cellular level is unknown. We assessed alterations in cellular bioenergetics in peripheral blood mononuclear cells (PBMC) before and after a 12-week aerobic exercise study in sedentary HIV-infected subjects on stable antiretroviral therapy who successfully completed a 12-week aerobic exercise program. In this prospective study, participants underwent supervised 20-40 min of light aerobic exercise (walking or jogging) performed three times per week for 12 weeks, gradually increasing to maintain an intensity of 50%-80% of heart rate reserve. Maximal aerobic capacity (VO 2MAX ) was assessed by a graded exercise test on a cycle ergometer before and after completion of the study. PBMC from compliant subjects (attended at least 70% of exercise sessions) were assessed for mitochondrial respiration using the Seahorse XF24 Bio-Analyzer. Seven of 24 enrolled subjects were compliant with the exercise regimen. In these individuals, a significant increase (p = .04) in VO 2MAX over 12 weeks was found with a median increase of 14%. During the same interval, a 2.45-fold increase in PBMC mitochondrial respiratory capacity (p = .04), a 5.65-fold increase in spare respiratory capacity (p = .01), and a 3.15-fold (p = .04) increase in nonmitochondrial respiration was observed. Aerobic exercise improves respiration at the cellular level. The diagnostic and prognostic value of such improved cellular respiration in the setting of chronic HIV warrants further investigation.

    Substantial evidence in critical care literature identifies a lack of quality and quantity of communication between patients, families, and clinicians while in the intensive care unit. Barriers include time, multiple caregivers, communication skills, culture, language, stress, and optimal meeting space. For patients who are chronically critically ill, the need for a structured method of communication is paramount for discussion of goals of care. The objective of this quality improvement project was to identify barriers to communication, then develop, implement, and evaluate a process for semistructured family meetings in a 9-bed respiratory care unit. Using set dates and times, family meetings were offered to patients and families admitted to the respiratory care unit. Multiple avenues of communication were utilized to facilitate attendance. Utilizing evidence-based family meeting literature, a guide for family meetings was developed. Templates were developed for documentation of the family meeting in the electronic medical record. Multiple communication barriers were identified. Frequency of family meeting occurrence rose from 31% to 88%. Staff satisfaction with meeting frequency, meeting length, and discussion of congruent goals of care between patient/family and health care providers improved. Patient/family satisfaction with consistency of message between team members; understanding of medications, tests, and dismissal plan; and efficacy to address their concerns with the medical team improved. This quality improvement project was implemented to address the communication gap in the care of complex patients who require prolonged hospitalizations. By identifying this need, engaging stakeholders, and developing a family meeting plan to meet to address these needs, communication between all members of the patient's care team has improved.

    The scientist's primary incentive is publication. In the present culture, open practices do not increase chances of publication, and they often require additional work. Practicing the abstract scientific values of openness and reproducibility thus requires behaviors in addition to those relevant for the primary, concrete rewards. When in conflict, concrete rewards are likely to dominate over abstract ones. As a consequence, the reward structure for scientists does not encourage openness and reproducibility. This can be changed by nudging incentives to align scientific practices with scientific values. Science will benefit by creating and connecting technologies that nudge incentives while supporting and improving the scientific workflow. For example, it should be as easy to search the research literature for my topic as it is to search the Internet to find hilarious videos of cats falling off of furniture. I will introduce the Center for Open Science (http://centerforopenscience.org/) and efforts to improve openness and reproducibility such as http://openscienceframework.org/. There will be no cats.

    The potential for model-data synthesis is growing in importance as we enter an era of 'big data', greater connectivity and faster computation. Realizing this potential requires that the research community broaden its perspective about how and why they interact with models. Models can be viewed as scaffolds that allow data at different scales to inform each other through our understanding of underlying processes. Perceptions of relevance, accessibility and informatics are presented as the primary barriers to broader adoption of models by the community, while an inability to fully utilize the breadth of expertise and data from the community is a primary barrier to model improvement. Overall, we promote a community-based paradigm to model-data synthesis and highlight some of the tools and techniques that facilitate this approach. Scientific workflows address critical informatics issues in transparency, repeatability and automation, while intuitive, flexible web-based interfaces make running and visualizing models more accessible. Bayesian statistics provides powerful tools for assimilating a diversity of data types and for the analysis of uncertainty. Uncertainty analyses enable new measurements to target those processes most limiting our predictive ability. Moving forward, tools for information management and data assimilation need to be improved and made more accessible. © 2013 John Wiley & Sons Ltd.

    1978-01-01

    The basic methods for extracting and determining Zr(4) and Hf(4) are described. Diantipyrinemethane and its alkyl homologs selectively extract Zr and Hf from HNO 3 solutions in the presence of nitrates. Zr is selectively extracted with tetraethyldiamide of heptyl phosphoric acid (in benzene) as well as with 2-thenoyltrifluoroacetone (in an acid). The latter reagents is suitable for rapid determination of 95 Zr in a mixture with 95 Nb and other fragments. The complexometric determination of Zr is based on formation of a stable complex of Zr with EDTA. The titration is carried out in the presence of n-sulfobenzene-azo-pyrocatechol, eriochrome black T. The determination is hindered by Hf, fluoride-, phosphate-, oxalate- and tartrate-ions. The method is used for determining Zr in zircon and eudialyte ore. Zr is determined photometrically with the aid of xylenol orange, arsenazo 3 and pyrocatechol violet (in phosphorites). Hf is determined in the presence of Zr photometrically with the aid of xylenol orange or methyl-thymol blue. The method is based on Zr being masked with hydrogen peroxide in the presence of sulfate-ions

  19. Communicate to vaccinate”: the development of a taxonomy of communication interventions to improve routine childhood vaccination

    Science.gov (United States)

    2013-01-01

    Background Vaccination is a cost-effective public health measure and is central to the Millennium Development Goal of reducing child mortality. However, childhood vaccination coverage remains sub-optimal in many settings. While communication is a key feature of vaccination programmes, we are not aware of any comprehensive approach to organising the broad range of communication interventions that can be delivered to parents and communities to improve vaccination coverage. Developing a classification system (taxonomy) organised into conceptually similar categories will aid in: understanding the relationships between different types of communication interventions; facilitating conceptual mapping of these interventions; clarifying the key purposes and features of interventions to aid implementation and evaluation; and identifying areas where evidence is strong and where there are gaps. This paper reports on the development of the ‘Communicate to vaccinate’ taxonomy. Methods The taxonomy was developed in two stages. Stage 1 included: 1) forming an advisory group; 2) searching for descriptions of interventions in trials (CENTRAL database) and general health literature (Medline); 3) developing a sampling strategy; 4) screening the search results; 5) developing a data extraction form; and 6) extracting intervention data. Stage 2 included: 1) grouping the interventions according to purpose; 2) holding deliberative forums in English and French with key vaccination stakeholders to gather feedback; 3) conducting a targeted search of grey literature to supplement the taxonomy; 4) finalising the taxonomy based on the input provided. Results The taxonomy includes seven main categories of communication interventions: inform or educate, remind or recall, teach skills, provide support, facilitate decision making, enable communication and enhance community ownership. These categories are broken down into 43 intervention types across three target groups: parents or soon

    Cultural diversity between residents and staff is significant in aged care homes in many developed nations in the context of international migration. This diversity can be a challenge to achieving effective cross-cultural communication. The aim of this study was to critically examine how staff and residents initiated effective cross-cultural communication and social cohesion that enabled positive changes to occur. A critical hermeneutic analysis underpinned by Giddens' Structuration Theory was applied to the study. Data were collected by interviews with residents or their family and by focus groups with staff in four aged care homes in Australia. Findings reveal that residents and staff are capable of restructuring communication via a partnership approach. They can also work in collaboration to develop communication resources. When staff demonstrate cultural humility, they empower residents from culturally and linguistically diverse backgrounds to engage in effective communication. Findings also suggest that workforce interventions are required to improve residents' experiences in cross-cultural care. This study challenges aged care homes to establish policies, criteria and procedures in cross-cultural communication. There is also the challenge to provide ongoing education and training for staff to improve their cross-cultural communication capabilities. © 2017 John Wiley & Sons Ltd.

    Effective communication is critical to patient satisfaction, outcomes of care and malpractice prevention. Surgeons need particularly effective communication skills to discuss complicated procedures and help patients make informed choices. We conducted a systematic review of the literature on surgeon-patient communication. Searches were conducted in MEDLINE, PsycINFO, and Sociological Abstract. Two reviewers screened citations and full-text articles. Quality was appraised using the Critical Appraisal Skills Program tool. Studies were categorized into content of communication, patient satisfaction, relationship of communication to malpractice, and duration of visits. 2794 citations and 74 full-text articles, 21 studies and 13 companion reports were included. Surgeons spent the majority of their time educating patients and helping them to make choices. Surgeons were generally thorough in providing details about surgical conditions and treatments. Surgeons often did not explore the emotions or concerns of patients. Potential areas of improvement included discussing some elements of informed decision making, and expressing empathy. Surgeons can enhance their communication skills, particularly in areas of relative deficiency. Studies in primary care demonstrate communication programs are effective in teaching these skills. These can be adapted to surgical training and ultimately lead to improved outcomes and satisfaction with care. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    We investigate the robustness of complex communication networks on allocating redundancy links. The protecting key nodes (PKN) strategy is proposed to improve the robustness of complex communication networks against intentional attack. Our numerical simulations show that allocating a few redundant links among key nodes using the PKN strategy will significantly increase the robustness of scale-free complex networks. We have also theoretically proved and demonstrated the effectiveness of the PKN strategy. We expect that our work will help achieve a better understanding of communication networks. (paper)

    For the Cooperative Adaptive Cruise Control (CACC) Algorithm, existing research studies mainly focus on how inter-vehicle communication can be used to develop CACC controller, the influence of the communication delays and lags of the actuators to the string stability. However, whether the string stability can be guaranteed when inter-vehicle communication is invalid partially has hardly been considered. This paper presents an improved CACC algorithm based on the sliding mode control theory and analyses the range of CACC controller parameters to maintain string stability. A dynamic model of vehicle spacing deviation in a platoon is then established, and the string stability conditions under improved CACC are analyzed. Unlike the traditional CACC algorithms, the proposed algorithm can ensure the functionality of the CACC system even if inter-vehicle communication is partially invalid. Finally, this paper establishes a platoon of five vehicles to simulate the improved CACC algorithm in MATLAB/Simulink, and the simulation results demonstrate that the improved CACC algorithm can maintain the string stability of a CACC platoon through adjusting the controller parameters and enlarging the spacing to prevent accidents. With guaranteed string stability, the proposed CACC algorithm can prevent oscillation of vehicle spacing and reduce chain collision accidents under real-world circumstances. This research proposes an improved CACC algorithm, which can guarantee the string stability when inter-vehicle communication is invalid.

    Important gaps are observed in clinicians' communication with patients and families about psychiatric disorders such as schizophrenia. Communication skills can be taught, and models for education in these skills have been developed in other fields of medicine, such as oncology, providing a framework for training communication skills relevant to psychiatric practice. This study evaluated a pilot communication skills education program for psychiatry trainees, focusing on discussing schizophrenia diagnosis and prognosis. Communication skills training modules were developed based on an existing theoretical framework (ComSkil), adapted for discussing a schizophrenia diagnosis and prognosis. Pre-post training rating of self-reported confidence in a range of communication tasks was obtained, along with trainee views on the training methods. Thirty-eight participants completed the training. Significant improvements in confidence were reported post training for discussing schizophrenia prognosis, including an increased capacity to critically evaluate their own communication skills. Participants reported high levels of satisfaction with the program. This preliminary study provides support for the translation of a well-established educational model to psychiatric training addressing core clinical communication tasks and provides the foundation for the development of a more comprehensive evaluation and an extended curriculum regarding other aspects of care for patients with schizophrenia: ongoing management and recovery, dealing with conflict, and conducting a family interview.

    Purpose: To compare the content, clarity, and clinical usefulness of conventional (ie, free-form) and structured radiology reports of body computed tomographic (CT) scans, as evaluated by referring physicians, attending radiologists, and radiology fellows at a tertiary care cancer center. Materials and Methods: The institutional review board approved the study as a quality improvement initiative; no written consent was required. Three radiologists, three radiology fellows, three surgeons, and two medical oncologists evaluated 330 randomly selected conventional and structured radiology reports of body CT scans. For nonradiologists, reports were randomly selected from patients with diagnoses relevant to the physician’s area of specialization. Each physician read 15 reports in each format and rated both the content and clarity of each report from 1 (very dissatisfied or very confusing) to 10 (very satisfied or very clear). By using a previously published radiology report grading scale, physicians graded each report’s effectiveness in advancing the patient’s position on the clinical spectrum. Mixed-effects models were used to test differences between report types. Results: Mean content satisfaction ratings were 7.61 (95% confidence interval [CI]: 7.12, 8.16) for conventional reports and 8.33 (95% CI: 7.82, 8.86) for structured reports, and the difference was significant (P radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11101913/-/DC1 PMID:21518775

    The InBox messaging system is an internal, electronic program used at Mayo Clinic, Rochester, MN, to facilitate the sending, receiving, and answering of patient-specific messages and alerts. A standardized InBox was implemented in the Division of General Internal Medicine to decrease the time physicians, physician assistants, and nurse practitioners (clinicians) spend on administrative tasks and to increase efficiency. Clinicians completed surveys and a preintervention InBox pilot test to determine inefficiencies related to administrative burdens and defects (message entry errors). Results were analyzed using Pareto diagrams, value stream mapping, and root cause analysis to prioritize administrative-burden inefficiencies to develop a new, standardized InBox. Clinicians and allied health staff were the target of this intervention and received standardized InBox training followed by a postintervention pilot test for clinicians. Sixteen of 28 individuals (57%) completed the preintervention survey. Twenty-eight clinicians participated in 2 separate 8-day pilot tests (before and after intervention) for the standardized InBox. The number of InBox defects was substantially reduced from 37 (Pilot 1) to 7 (Pilot 2). Frequent InBox defects decreased from 25% to 10%. More than half of clinicians believed the standardized InBox positively affected their work, and 100% of clinicians reported no negative affect on their work. This project demonstrated the successful implementation of the standardized InBox messaging system. Initial assessments show substantial reduction of InBox entry defects and administrative tasks completed by clinicians. The findings of this project suggest increased clinician and allied health staff efficiency, satisfaction, improved clinician work-life balance, and decreased clinician burden caused by administrative tasks.

    Different applications of radio systems are based on the implementation of antenna arrays. Classically, radio direction

    finding operates with a multi channel receiving system connected to an array of receiving antennas. More

    recently, MIMO architectures have been proposed to increase the capacity of radio links by the use of antenna

    arrays at both the transmitter and receiver.

    The first part of this paper describes some novel experimental work carried out to examine the feasibility of applying

    MIMO techniques for communications within the HF radio band. A detailed correlation analysis of a variety

    of different antenna array configurations is presented. The second section of the paper also deals with HF

    MIMO communications, focusing on the problem from a modelling point of view. The third part presents a sensitivity

    analysis of different antenna array structures for HF direction finding applications. The results demonstrate

    that when modelling errors, heterogeneous antenna arrays are more robust in comparison to homogeneous structures

    The discharge letter is the primary means of communication at patient discharge, yet discharge letters are often not completed on time. A multifaceted intervention was performed to improve communication in patient hand-off from the intensive care unit (ICU) to the wards by improving the timeliness of discharge letters. A management directive was operationalised by a working group of ICU staff in a longitudinal before-after study. The intervention consisted of (a) changing policy to require a letter for use as a transfer note at the time of ICU discharge, (b) changing the assignment of responsibility to an automatic process, (c) leveraging positive peer pressure by making the list of patients in need of letters visible to colleagues and (d) provision of decision support, through automatic copying of important content from the patient record to the letter and email reminders if letters were not written on time. Statistical process control charts were used to monitor the longitudinal effect of the intervention. The intervention resulted in a 77.9% absolute improvement in the proportion of patients with a complete transfer note at the time of discharge, and an 85.2% absolute improvement in the number of discharge letters written. Statistical process control shows that the effect was sustained over time. A multifaceted intervention can be highly effective for improving discharge communication from the ICU.

    Crew Resource Management (CRM) is a team-building communication process first implemented in the aviation industry to improve safety. It has been used in health care, particularly in surgical and intensive care settings, to improve team dynamics and reduce errors. We adapted a CRM process for implementation in the trauma resuscitation area. An interdisciplinary steering committee developed our CRM process to include a didactic classroom program based on a preimplementation survey of our trauma team members. Implementation with new cultural and process expectations followed. The Human Factors Attitude Survey and Communication and Teamwork Skills assessment tool were used to design, evaluate, and validate our CRM program. The initial trauma communication survey was completed by 160 team members (49% response). Twenty-five trauma resuscitations were observed and scored using Communication and Teamwork Skills. Areas of concern were identified and 324 staff completed our 3-hour CRM course during a 3-month period. After CRM training, 132 communication surveys and 38 Communication and Teamwork Skills observations were completed. In the post-CRM survey, respondents indicated improvement in accuracy of field to medical command information (p = 0.029); accuracy of emergency department medical command information to the resuscitation area (p = 0.002); and team leader identity, communication of plan, and role assignment (p = 0.001). After CRM training, staff were more likely to speak up when patient safety was a concern (p = 0.002). Crew Resource Management in the trauma resuscitation area enhances team dynamics, communication, and, ostensibly, patient safety. Philosophy and culture of CRM should be compulsory components of trauma programs and in resuscitation of injured patients. Copyright © 2014 American College of Surgeons. Published by Elsevier Inc.

    The increasing size and complexity of US dairy farms could make it more difficult for a veterinary practitioner to effectively communicate protocol recommendations for prevention or treatment on the farm. A continuing education workshop was set up based on the results of research on dairy organizational communication on dairy farms, which resulted in a tool to assess dairy communication structure and flow. The workshop specifically focused on communication structure and whom to talk to when implementing health care changes in calf rearing. In addition, modern methods of veterinary-client communication knowledge and skills were provided. Primary outcomes of the workshops were to obtain feedback from participants about research findings and the communication model, to improve awareness about the complexity of communication structures on dairy farms, and to change participants' knowledge and skills associated with on-farm communication by providing communication theory and skills and an approach to evaluate and improve dairy organizational communication. Of the 37 participants completing the pre-program assessment, most recognized a need for themselves or their practice to improve communication with clients and farm employees. After the program, most participants were confident in their new communication skills and would consider using them. They highlighted specific new ideas they could apply in practice, such as conducting a "communication audit." The results from the assessment of this communication workshop, focused on dairy veterinarians, highlighted the need for communication training in this sector of the profession and practitioners' desire to engage in this type of training.

    Effective communication is a requirement in the teamwork necessary for improved coordination to deliver patient-centered, value-based cancer care. Communication is particularly important when care providers are geographically distributed or work across organizations. We review organizational and teams research on communication to highlight psychological safety as a key determinant of high-quality communication within teams. We first present the concept of psychological safety, findings about its communication effects for teamwork, and factors that affect it. We focus on five factors applicable to cancer care delivery: familiarity, clinical hierarchy-related status differences, geographic dispersion, boundary spanning, and leader behavior. To illustrate how these factors facilitate or hinder psychologically safe communication and teamwork in cancer care, we review the case of a patient as she experiences the treatment-planning process for early-stage breast cancer in a community setting. Our analysis is summarized in a key principle: Teamwork in cancer care requires high-quality communication, which depends on psychological safety for all team members, clinicians and patients alike. We conclude with a discussion of the implications of psychological safety in clinical care and suggestions for future research.

    Transferring patients from the ward of their specialty or consultant is described as boarding. 1 Boarding patients is becoming increasingly prevalent due to greater pressure on hospital capacity. This practice compromises patient safety through delayed investigations, prolonged hospital stays, and increased risk of hospital-acquired infections. 1 2 We evaluated how regularly boarded patients were reviewed, and how effectively information regarding their management was communicated from their primary specialty to ward staff. We aimed to improve the frequency of patient reviews by ensuring that each patient was reviewed every weekday and increase communication between primary specialty, and medical and nursing teams by 20% from baseline during the data collection period. The project was based in the Otolaryngology ward in Ninewells Hospital, Dundee, where there was a high prevalence of boarded patients. Baseline data showed a clear deficit in communication between the primary specialty and ward staff with only 31% of patient reviews being communicated to ward doctors. We designed and implemented a communication tool, in the form of a sticker, to be inserted into patients' medical notes for use by the primary specialty. Implementation of the sticker improved communication between teams as stickers were completed in 93% of instances. In 88% of patient reviews, the junior doctor was informed of the management plan, showing a large increase from baseline. Through PDSA cycles, we aimed to increase the sustainability and reliability of the sticker; however, we faced challenges with sustainability of sticker insertion. We aim to engage more stakeholders to raise awareness of the problem, brainstorm solutions together, and review the production and implementation of stickers with senior hospital management to discuss the potential use of this tool within practice. There is potentially a large scope for utilisation of this communication tool on a local level, which we hope

    Efficient and effective communication between providers is critical to quality patient care within a hospital system. Hands free communication devices (HFCD) allow instantaneous, closed-loop communication between physicians and other members of a multidisciplinary team, providing a communication advantage over traditional pager systems. HFCD have been shown to decrease emergency room interruptions, improve nursing communication, improve speed of information flow, and eliminate health care waste. We evaluated the integration of an HFCD with an existing alphanumeric paging system on an acute inpatient medicine service. We conducted a prospective, observational, survey-based study over twenty-four weeks in an academic tertiary care center with attending physicians and residents. Our intervention involved the implementation of an HFCD alongside the existing paging system. Fifty-six pre and post surveys evaluated the perception of improvement in communication and the integration of the HFCD into existing workflow. We saw significant improvements in the ability of an HFCD to help physicians communicate thoughts clearly, communicate thoughts effectively, reach team members, reach ancillary staff, and stay informed about patients. Physicians also reported better workflow integration during admissions, rounds, discharge, and teaching sessions. Qualitative data from post surveys demonstrated that the greatest strengths of the HFCD included the ability to reach colleagues and staff quickly, provide instant access to individuals of the care team, and improve overall communication. Integration of an instantaneous, hands free, closed loop communication system alongside the existing pager system can provide improvements in the perceptions of communication and workflow integration in an academic medicine service. Future studies are needed to correlate these subjective findings with objective measures of quality and safety.

    Although visual functions have been proposed to be enhanced in deaf individuals, empirical studies have not yet established clear evidence on this issue. The present study aimed to determine whether deaf children with diverse communication modes had superior visual memory and whether their performance was improved by the use of differential outcomes. Severely or profoundly deaf children who employed spoken Spanish, Spanish Sign Language (SSL), and both spoken Spanish and SSL modes of communication were tested in a delayed matching-to-sample task for visual working memory assessment. Hearing controls were used to compare performance. Participants were tested in two conditions, differential outcome and non-differential outcome conditions. Deaf groups with either oral or SSL modes of communication completed the task with less accuracy than bilingual and control hearing children. In addition, the performances of all groups improved through the use of differential outcomes. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2010-01-01

    Given the recent problem of climate change, nuclear power has become perhaps the world's most important energy source. In Japan, however, it is difficult to build new nuclear facilities. One of the reasons for such difficulty lies in problems in risk communication. In this study, a support method has been proposed to improve mutual understanding in risk communication. The authors paid especial attention at the learning effect of debating and the benefits of employing a debate support system. A laboratory experiment including 30 university students was conducted in order to evaluate the proposed method. Results showed that the use of the system could improve mutual understanding especially with respect to the factors of risk 'reduction measures' and 'accident management'. In addition, it was found that using the system and debating from 'opposite positions' could improve subjective mutual understanding; however, this practice showed no effectiveness in terms of improving objective mutual understanding.

    Improved switching characteristics were obtained from high-κ oxides AlOx, GdOx, HfOx, and TaOx in IrOx/high-κx/W structures because of a layer that formed at the IrOx/high-κx interface under external positive bias. The surface roughness and morphology of the bottom electrode in these devices were observed by atomic force microscopy. Device size was investigated using high-resolution transmission electron microscopy. More than 100 repeatable consecutive switching cycles were observed for positive-formatted memory devices compared with that of the negative-formatted devices (only five unstable cycles) because it contained an electrically formed interfacial layer that controlled 'SET/RESET' current overshoot. This phenomenon was independent of the switching material in the device. The electrically formed oxygen-rich interfacial layer at the IrOx/high-κx interface improved switching in both via-hole and cross-point structures. The switching mechanism was attributed to filamentary conduction and oxygen ion migration. Using the positive-formatted design approach, cross-point memory in an IrOx/AlOx/W structure was fabricated. This cross-point memory exhibited forming-free, uniform switching for >1,000 consecutive dc cycles with a small voltage/current operation of ±2 V/200 μA and high yield of >95% switchable with a large resistance ratio of >100. These properties make this cross-point memory particularly promising for high-density applications. Furthermore, this memory device also showed multilevel capability with a switching current as low as 10 μA and a RESET current of 137 μA, good pulse read endurance of each level (>105 cycles), and data retention of >104 s at a low current compliance of 50 μA at 85°C. Our improvement of the switching characteristics of this resistive memory device will aid in the design of memory stacks for practical applications.

  7. Application of HF Radar in Hazard Management

    Mal Heron

    2016-01-01

    Full Text Available A review is given of the impact that HF radars are having on the management of coastal hazards. Maps of surface currents can be produced every 10–20 minutes which, in real time, improve navigation safety in restricted areas commonly found near ports and harbours. The time sequence of surface current maps enables Lagrangian tracking of small parcels of surface water, which enables hazard mitigation in managing suspended sediments in dredging, in emergency situations where flotsam and other drifting items need to be found, and in pollution control. The surface current measurement capability is used to assist tsunami warnings as shown by the phased-array data from Chile following the Great Tohoku Earthquake in 2011. The newly launched Tsunami Warning Center in Oman includes a network of phased-array HF radars to provide real-time tsunami monitoring. Wind direction maps can be used to locate the position of cold fronts in the open ocean and to monitor the timing and strength of sea-breeze fronts in key locations.

    Objective. To design and implement a series of activities focused on developing interprofessional communication skills and to assess the impact of the activities on students' attitudes and achievement of educational goals. Design. Prior to the first pharmacy practice skills laboratory session, pharmacy students listened to a classroom lecture about team communication and viewed short videos describing the roles, responsibilities, and usual work environments of four types of health care professionals. In each of four subsequent laboratory sessions, students interacted with a different standardized health care professional role-played by a pharmacy faculty member who asked them a medication-related question. Students responded in verbal and written formats. Assessment. Student performance was assessed with a three-part rubric. The impact of the exercise was assessed by conducting pre- and post-intervention surveys and analyzing students' performance on relevant Center for the Advancement of Pharmacy Education (CAPE) outcomes. Survey results showed improvement in student attitudes related to team-delivered care. Students' performance on the problem solver and collaborator CAPE outcomes improved, while performance on the educator outcome worsened. Conclusions. The addition of an interprofessional communication activity with standardized health care professionals provided the opportunity for students to develop skills related to team communication. Students felt the activity was valuable and realistic; however, analysis of outcome achievement from the exercise revealed a need for more exposure to team communication skills.

  9. Assistive Technologies for Improving Communication of Hearing Impairment in the Higher Education in Panama

    2016-12-01

    Full Text Available The ability to communicate, specifically the gift of hearing, is a necessity often taken for granted. A lack of sense of hearing affects the intellectual and emotional development of the human being who suffers from it. It prevents the fluid exchange of knowledge, thoughts and ideas that allow personal growth and development. This article emerges due to an interest in providing assistive technologies that can be considered to improve communication among hearing impaired and normal hearing listeners in the class-room of a higher education level in the Republic of Panama. Information has been compiled from various primary and secondary sources highlighting the communication problem facing this group of disabled people. Information about the situation of hearing impairment, laws, organizations, the reality with the higher education system, and finally, we will talk about Information and Communication Technologies (TICs that will work as technology support in order to improve communication in the classroom in higher education among normal-hearing and deaf people.

  10. Improving together: collaborative learning in science communication, ClimateSnack case study

    Heuzé, C.; Reeve, M. A.

    2016-02-01

    Most scientists today recognize that science communication is an important part of the scientific process, yet science writing and communication are often taught outside the normal academic schedule. If universities offer such courses, they are generally intensive but short-term: the participants rarely complete a science communication course with an immediate and pressing need to apply these skills. So the skills fade, stalling real progress in science communication. Continuity is key to success! Whilst waiting for the academic system to truly integrate science communication, other methods can be tested. ClimateSnack / SciSnack is a new approach that aims to motivate scientists to develop their communication skills. It adopts a collaborative learning framework where scientists voluntarily form writing groups that meet regularly at different institutes around the world. The members of the groups learn, discuss and improve together. The participants produce short posts, which are published online, where they are further discussed and improved by the global ClimateSnack community. This way, the participants learn and cement basic science communication skills. These skills are transferrable, and can be applied both to scientific articles and broader science media. Some writing groups are highly productive, while others exist no more. The reasons for success are here investigated with respect to issues both internal and external to the different groups, in particular leadership strategies. Possible further development, in particular using the online community, is suggested. ClimateSnack is one solution to fill the critical gap left by a lack of adequate teaching in early-career scientists' curriculum.

    Interprofessional communication and collaboration are promoted by policymakers as fundamental building blocks for improving patient safety and meeting the demands of increasingly complex care. This paper reports qualitative findings of an interprofessional intervention designed to improve communication and collaboration between different professions in general internal medicine (GIM) hospital wards in Canada. The intervention promoted self-introduction by role and profession to a collaborating colleague in relation to the shared patient, a question or communication regarding the patient, to be followed by an explicit request for feedback from the partner professional. Implementation and uptake of the intervention were evaluated using qualitative methods, including 90 hours of ethnographic observations and interviews collected in both intervention and comparison wards. Documentary data were also collected and analysed. Fieldnotes and interviews were transcribed and analysed thematically. Our findings suggested that the intervention did not produce the anticipated changes in communication and collaboration between health professionals, and allowed us to identify barriers to the implementation of effective collaboration interventions. Despite initially offering verbal support, senior physicians, nurses, and allied health professionals minimally explained the intervention to their junior colleagues and rarely role-modelled or reiterated support for it. Professional resistances as well as the fast paced, interruptive environment reduced opportunities or incentive to enhance restrictive interprofessional relationships. In a healthcare setting where face-to-face spontaneous interprofessional communication is not hostile but is rare and impersonal, the perceived benefits of improvement are insufficient to implement simple and potentially beneficial communication changes, in the face of habit, and absence of continued senior clinician and management support.

    Written and verbal communication skills are important skills for all physicians. While verbal skills are taught and assessed in medical school, medical students report limited instruction in written communication skills. This study examined the impact of a curriculum delivered during a 6-week clinical rotation in Internal Medicine on the objective assessment of medical students' written communication skills. The curriculum consisted of two educational programmes: a medical student communication tutorial and a resident feedback workshop. The study was conducted from March 2012 to January 2013 at McMaster University in Hamilton, Ontario, Canada. The study featured three arms: (1) control, (2) medical student communication tutorial alone and (3) student tutorial and resident feedback workshop. Data were collected on 126 students during 6-week Internal Medicine clerkship rotations. Students' written consultation notes were collected prior to the educational programmes and at 6 weeks. Blinded faculty assessors used an independently validated Assessment Checklist to evaluate consultation notes. Consultation note scores improved from week 1 to week 6 across all study arms. However, the change was statistically significant only in arm 3, featuring both the medical student tutorial and the resident feedback workshop, with mean scores improving from 4.75 (SD=1.496) to 5.56 (SD=0.984) out of 7. The mean difference between week 1 and week 6 was significantly different (0.806, p=0.002, 95% CI 0.306 to 1.058). The combination of a resident feedback workshop with medical student written communication tutorial improves objective evaluations of consultation note scores over student tutorial alone.

  15. Science and Improv: Saying "YES" to Creative Collaboration and Scintillating Communication

    2015-12-01

    Communicating research results to a non-specialist audience can be challenging. Strategies that work well in lab group meetings, such as using acronyms and jargon, may fall flat with 7th graders or Congressional staffers. Empowering real-world audiences with our stories helps raise awareness and inform decision-making, whether it's related to family food purchases or national policy. Ideally, we scientists, engineers and researchers directly connect with our audiences, responding spontaneously and actively, distilling our messages into conversational morsels that resonate with them. One tool that I have found useful is deeply rooted in the "tao" of improvisational theater. Why improv? Improv is dancing as if no one is watching, baking from scratch, and playing jazz flute. Improv is Iron Chef, MacGyver with a license to thrill, or the game-winning play. Research is inspired improvisation. And improv can teach us a lot about how to play, how to feel comfortable and present even while flailing, and how to truly listen. Effective science communicators listen. In fact, therein lies the power of "yes …", a building block of improvisational theater. "Yes …" is both collaborative ("yes, and …") and innovative ("yes, because …"), and investment in an attitude of saying "yes …" demonstrates an intent to listen. Improv is not any one specific thing so much as a process by which we do things. Skills that strengthen communication, such as spontaneity, authenticity and connectivity, are honed through philosophies inherent in improv. This presentation highlights improv-based activities that enhance science communication with purpose, vividness, and emotion.

    Lateral parotidectomy is a demanding surgical procedure and requires a large number of instruments with a high frequency (HF) of alternating. Many functions, such as preparing, spreading, coagulating and cutting could be combined by using scissors with an integrated function of bipolar coagulation. This study has targeted an investigation of technical application, influence on surgery time, frequency of HF application and change of instruments. In the period between 01 April 2011 and 30 September 2012 (18 months) 35 procedures of lateral parotidectomy in 35 patients were investigated. In all cases lateral parotidectomy was carried out with a similar technique (modified extracapsular preparation). Workflow data were used from a control group in the period between 01 January 2009 and 31 December 2010 (24 months). The following parameters from both groups were documented and evaluated: incision-suture times (subdivided into nine sections of the procedure), change of instruments, period of application for HF function and early facial nerve function (6 h and 6 days after surgery according to House-Brackmann). Additionally, in the HF+ group a questionnaire that facilitated subjective evaluation of instruments was analyzed. It was possible to perform the surgery in both groups with neither technical nor surgical intraoperative complications. Incision-suture times showed an average reduction of 31.6 min (34.8 %) in the HF+ group. There was a reduction in the change of instruments compared to a conventional group (CONV) by up to 62.7 %. With the deployment of HF scissors there was a clear increase in the use of HF surgery by more than 100 % when comparing incision-suture times. Evaluation of both groups according to House-Brackmann showed a similar postoperative facial nerve function. The surgeons involved were of the opinion that in all 35 surgeries with HF scissors the intervention was easier and more comfortable. The use of HF scissors is appropriate for parotid gland

    Ineffective communication of infection control requirements during transitions of care is a potential cause of non-compliance with infection control precautions by healthcare personnel. In this study, interventions to enhance communication during inpatient transfers between wards and radiology were implemented, in the attempt to improve adherence to precautions during transfers. Two interventions were implemented, comprising (i) a pre-transfer checklist used by radiology porters to confirm a patient's infectious status; (ii) a coloured cue to highlight written infectious status information in the transfer form. The effectiveness of the interventions in promoting adherence to standard precautions by radiology porters when transporting infectious patients was evaluated using a randomised crossover trial at a teaching hospital in Australia. 300 transfers were observed over a period of 4 months. Compliance with infection control precautions in the intervention groups was significantly improved relative to the control group (p group was 38%. Applying the coloured cue resulted in a compliance rate of 73%. The pre-transfer checklist intervention achieved a comparable compliance rate of 71%. When both interventions were applied, a compliance rate of 74% was attained. Acceptability of the coloured cue was high, but adherence to the checklist was low (40%). Simple measures to enhance communication through the provision of a checklist and the use a coloured cue brought about significant improvement in compliance with infection control precautions by transport personnel during inpatient transfers. The study underscores the importance of effective communication in ensuring compliance with infection control precautions during transitions of care.

  19. The rotational excitation of HF by H

    Desrousseaux, Benjamin; Lique, François

    2018-06-01

    The HF molecule is a key tracer of molecular hydrogen in diffuse interstellar medium (ISM). Accurate modelling of the HF abundance in such media requires one to model its excitation by both radiation and collisions. In diffuse ISM, the dominant collisional partners are atomic and molecular hydrogen. We report quantum time-independent calculations of collisional cross-sections and rate coefficients for the rotational excitation of HF by H. The reactive hydrogen exchange channels are taken into account in the scattering calculations. For the first time, HF-H rate coefficients are provided for temperature ranging from 10 to 500 K. The strongest collision-induced rotational HF transitions are those with Δj = 1, and the order of magnitude of the new HF-H rate coefficients is similar to that of the HF-H2 ones previously computed. As a first application, we simulate the excitation of HF by both H and H2 in typical diffuse ISM. We show that, depending on the rotational transition, hydrogen atoms increase or decrease the simulated excitation temperatures compared to collisional excitation only due to H2 molecules. Such results suggest that the new HF-H collisional data have to be used for properly modelling the abundance of HF in diffuse ISM.

    Science.gov (United States)

    Cooke, Marcia

    2016-07-01

    Ineffective communication among the health care team is a leading cause of errors in the patient care setting. Studies assessing training related to communication and teamwork in the clinical team are prevalent, however, teamwork training at the administrative level is lacking. This includes individuals in leadership positions such as health care risk managers. The purpose was to determine the impact of an educational intervention on the knowledge and attitudes related to communication and teamwork in the health care risk management population. The educational intervention was an adaptation of a national teamwork training program and incorporated didactic content as well as video vignettes and small group activities. Measurement of knowledge and attitudes were used to determine the impact of the education program. Knowledge and attitudes were assessed pre- and postcourse. Findings indicate that teamwork education tailored to the needs of the specific audience resulted in knowledge gained and improved attitudes toward the components of teamwork. The attitudes that most significantly improved were related to team structure and situation monitoring. There was no improvement in participants' attitudes toward leadership, mutual support, and communication. Team training has been shown to improve safety culture, patient satisfaction, and clinical outcomes. Including risk managers in training on teamwork, communication, and collaboration can serve to foster a common language among clinicians and management. In addition, a measurement related to implementation in the health care setting may yield insight into the impact of training. Qualitative measurement may allow the researcher to delve deeper into how these health care facilities are using team training interventions. © 2016 American Society for Healthcare Risk Management of the American Hospital Association.

    2013-12-01

    The aim of this systematic review was to assess the impact of surgical safety checklists on the quality of teamwork and communication in the operating room (OR). Safety checklists have been shown to impact positively on patient morbidity and mortality following surgery, but it is unclear whether this clinical improvement is related to an improvement in OR teamwork and communication. A systematic search strategy of MEDLINE, EMBASE, PsycINFO, Google Scholar, and the Cochrane Database for Systematic Reviews was undertaken to obtain relevant articles. After de-duplication and the addition of limits, 315 articles were screened for inclusion by 2 researchers and all articles meeting a set of prespecified inclusion criteria were retained. Information regarding the type of checklist, study design, assessment tools used, outcomes, and study limitations was extracted. Twenty articles formed the basis of this systematic review. All articles described an empirical study relating to a case-specific safety checklist for surgery as the primary intervention, with some measure of change/improvement in teamwork and/or communication relating to its use. The methods for assessing teamwork and communication varied greatly, including surveys, observations, interviews, and 360° assessments. The evidence suggests that safety checklists improve the perceived quality of OR teamwork and communication and reduce observable errors relating to poor team skills. This is likely to function through establishing an open platform for communication at the start of a procedure: encouraging the sharing of critical case-related information, promoting team coordination and decision making, flagging knowledge gaps, and enhancing team cohesion. However, the evidence would also suggest that when used suboptimally or when individuals have not bought in to the process, checklists may conversely have a negative impact on the function of the team. Safety checklists are beneficial for OR teamwork and

    Recently, Chou et al. (Electron Commer Res 14:349-367, 2014) presented a novel controlled quantum secure direct communication protocol which can be used for online shopping. The authors claimed that their protocol was immune to the attacks from both external eavesdropper and internal betrayer. However, we find that this protocol is vulnerable to the attack from internal betrayer. In this paper, we analyze the security of this protocol to show that the controller in this protocol is able to eavesdrop the secret information of the sender (i.e., the customer's shopping information), which indicates that it cannot be used for secure online shopping as the authors expected. Accordingly, an improvement of this protocol, which could resist the controller's attack, is proposed. In addition, we present another protocol which is more appropriate for online shopping. Finally, a discussion about the difference in detail of the quantum secure direct communication process between regular quantum communications and online shopping is given.

    Full Text Available Anxiety and inadequate motivation due to misapplication of some language teaching methodologies and learning materials have been shown to affect the Willingness to Communicate of students in EFL programs. This study used a Project-Based Language Learning to improve learning motivation and content relevance. Students were grouped into pairs to conduct fieldwork activities on their chosen topics and learned the English language that was suitable for describing their activities and outcomes. They interacted with content and peers through Web 2.0 environments. In the classroom, they engaged in communicative tasks in a jigsaw format and presented their projects where their peers used an online rubric and forum to give feedback. They also participated in a speech contest with peers outside their class or from another university in order to broaden their confidence. Findings from this study show that students were able to develop the language and evaluation skills for presentation. Additionally, they indicated a reduction in communication anxiety.

    In this letter, the effects of pre-CF 4 plasma treatment on Si for sputtered HfO 2 gate dielectrics are investigated. The significant fluorine was incorporated at the HfO 2 /Si substrate interface for a sample with the CF 4 plasma pretreatment. The Hf silicide was suppressed and Hf-F bonding was observed for the CF 4 plasma pretreated sample. Compared with the as-deposited sample, the effective oxide thickness was much reduced for the pre-CF 4 plasma treated sample due to the elimination of the interfacial layer between HfO 2 and Si substrate. These improved characteristics of the HfO 2 gate dielectrics can be explained in terms of the fluorine atoms blocking oxygen diffusion through the HfO 2 film into the Si substrate

    Communication is key to disaster risk management before, during and after a hazardous event occurs. In this study we used a participatory design approach to increase disaster preparedness levels around Turrialba volcano (Costa Rica) in collaboration with local communities. We organised five participatory workshops in communities around Turrialba volcano, 2 in February 2014 and a further 3 in May 2014. A total of 101 people attended and participants included the general public, decision makers and relevant government employees. The main finding of the workshops was that people want more information, specifically regarding 1) the activity level at the volcano and 2) how to prepare. In addition, the source of information was identified as an important factor in communication, with credibility and integrity being key. This outcome highlights a communication gap between the communities at risk and the institutions monitoring the volcano, who publish their scientific results monthly. This strong and explicitly expressed desire for more information should be acknowledged and responded to. However, this gives rise to the challenge of how to communicate: how to change the delivery and/or content of the messages already disseminated for greater effectiveness. In our experience, participatory workshops provide a successful mechanism for effective communication. However, critically evaluating the workshops reveals a number of challenges and opportunities, with the former arising from human, cultural and resource factors, specifically the need to develop people's capacity to participate, whereas the latter is predominantly represented by participant empowerment. As disasters are mostly felt at individual, household and community levels, improving communication, not at but with these stakeholders, is an important component of a comprehensive disaster resilience strategy. This work provides an initial insight into the potential value of participatory design approaches for

    Effective and timely communication is important for any surgical specialty to function. The use of smartphones is prevalent amongst doctors. Numerous smartphone applications offer the potential for fast and cost-effective communication. WhatsApp is a commonly used application that is free, easy to use, and capable of text and multimedia messaging. We report on the use of WhatsApp over a six month period in our unit. WhatsApp communication between non-consultant members of an orthopaedic team over a six-month period was analysed. Both the phones and the WhatsApp application were password-protected, and patient details were anonymised. A series of 20 communications using the hospital pager system and the telephone system were also analysed. A total of 5,492 messages were sent during the six-month period and were part of 1,916 separate communication events. The vast majority of messages, 5,090, were related to patient care. A total of 195 multimedia messages were sent and these included images of radiographs and wounds. When using the hospital telephones, the length of time spent on a communication averaged 5.78 minutes and using the hospital pager system averaged 7.45 minutes. Using the WhatsApp messaging system has potentially saved up to 7,664 minutes over the study period. All participants found WhatsApp easy to use and found it to be more efficient than the traditional pager system Conclusion: Compared to the traditional pager systems, the use of WhatsApp is easy, inexpensive, and reliable and can help improve the efficiency of communication within a surgical team.

    Historically, joint effort has been put on observing open ocean, organizing, homogenizing, sharing and reinforcing the impact of the acquired information based on one technology: ARGO with profilers Argo floats, EuroSites, ESONET-NoE, FixO3 for deep water platforms, Ferrybox for stations in ships of opportunities, and GROOM for the more recent gliders. This kind of networking creates synergies and makes easier the implementation of this source of data in the European Data exchange services like EMODnet, ROOSs portals, or any applied services in the Blue economy. One main targeted improvement in the second phase of EMODnet projects is the assembling of data along coastline. In that sense, further coordination is recommended between platform operators around a specific technology in order to make easier the implementation of the data in the platforms (4th EuroGOOS DATAMEQ WG). HF radar is today recognized internationally as a cost-effective solution to provide high spatial and temporal resolution current maps (depending on the instrument operation frequency, covering from a few kilometres offshore up to 200 km) that are needed for many applications for issues related to ocean surface drift or sea state characterization. Significant heterogeneity still exists in Europe concerning technological configurations, data processing, quality standards and data availability. This makes more difficult the development of a significant network for achieving the needed accessibility to HF Radar data for a pan European use. EuroGOOS took the initiative to lead and coordinate activities within the various observation platforms by establishing a number of Ocean Observing Task Teams such as HF-Radars. The purpose is to coordinate and join the technological, scientific and operational HF radar communities at European level. The goal of the group is on the harmonization of systems requirements, systems design, data quality, improvement and proof of the readiness and standardization of

  11. Control Strategies for Improving Energy Efficiency and Reliability in Autonomous Microgrids with Communication Constraints

    Directory of Open Access Journals (Sweden)

    Francisco Martins Portelinha Júnior

    2017-09-01

    Full Text Available Microgrids are a feasible path to deploy smart grids, an intelligent and highly automated power system. Their operation demands a dedicated communication infrastructure to manage, control and monitor the intermittent sources of energy and loads. Therefore, smart devices will be connected to support the growth of grid smartness increasing the dependency on communication networks, which consumes a high amount of power. In an energy-limited scenario, one of the main issues is to enhance the power supply time. Therefore, this paper proposes a hybrid methodology for microgrid energy management, integrated with a communication infrastructure to improve and to optimize islanded microgrid operation at maximum energy efficiency. The hybrid methodology applies some control management rules, such as intentional load shedding, priority load management, and communication energy saving. These energy saving rules establish a trade-off between increasing microgrid energy availability and communication system reliability. To achieve a compromised solution, a continuous time Markov chain model describes the impact of energy saving policies into system reliability. The proposed methodology is simulated and tested with the help of the modified IEEE 34 node test-system.

    To identify factors limiting the effectiveness of communication between Aboriginal patients with end-stage renal disease and healthcare workers, and to identify strategies for improving communication. Qualitative study, gathering data through (a) videotaped interactions between patients and staff, and (b) in-depth interviews with all participants, in their first language, about their perceptions of the interaction, their interpretation of the video record and their broader experience with intercultural communication. A satellite dialysis unit in suburban Darwin, Northern Territory. The interactions occurred between March and July 2001. Aboriginal patients from the Yolngu language group of north-east Arnhem Land and their medical, nursing and allied professional carers. Factors influencing the quality of communication. A shared understanding of key concepts was rarely achieved. Miscommunication often went unrecognised. Sources of miscommunication included lack of patient control over the language, timing, content and circumstances of interactions; differing modes of discourse; dominance of biomedical knowledge and marginalisation of Yolngu knowledge; absence of opportunities and resources to construct a body of shared understanding; cultural and linguistic distance; lack of staff training in intercultural communication; and lack of involvement of trained interpreters. Miscommunication is pervasive. Trained interpreters provide only a partial solution. Fundamental change is required for Aboriginal patients to have significant input into the management of their illness. Educational resources are needed to facilitate a shared understanding, not only of renal physiology, disease and treatment, but also of the cultural, social and economic dimensions of the illness experience of Aboriginal people.

    The effects of HfB2 and HfN additions on the microstructures and mechanical properties of TiB2-based ceramic tool materials were investigated. The results showed that the HfB2 additive not only can inhibit the TiB2 grain growth but can also change the morphology of some TiB2 grains from bigger polygons to smaller polygons or longer ovals that are advantageous for forming a relatively fine microstructure, and that the HfN additive had a tendency toward agglomeration. The improvement of flexural strength and Vickers hardness of the TiB2-HfB2 ceramics was due to the relatively fine microstructure; the decrease of fracture toughness was ascribed to the formation of a weaker grain boundary strength due to the brittle rim phase and the poor wettability between HfB2 and Ni. The decrease of the flexural strength and Vickers hardness of the TiB2-HfN ceramics was due to the increase of defects such as TiB2 coarse grains and HfN agglomeration; the enhancement of fracture toughness was mainly attributed to the decrease of the pore number and the increase of the rim phase and TiB2 coarse grains. The toughening mechanisms of TiB2-HfB2 ceramics mainly included crack bridging and transgranular fracture, while the toughening mechanisms of TiB2-HfN ceramics mainly included crack deflection, crack bridging, transgranular fracture, and the core-rim structure.

    One technique for ensuring continuity of wireless communication services and keeping a smooth transition on mobile communication networks is the soft handover technique. In the Soft Handover (SHO) technique the inclusion and reduction of Base Station from the set of active sets is determined by initiation triggers. One of the initiation triggers is based on the strong reception signal. In this paper we observed the influence of parameters of large-scale radio propagation models to improve the performance of mobile communications. The observation parameters for characterizing the performance of the specified mobile system are Drop Call, Radio Link Degradation Rate and Average Size of Active Set (AS). The simulated results show that the increase in altitude of Base Station (BS) Antenna and Mobile Station (MS) Antenna contributes to the improvement of signal power reception level so as to improve Radio Link quality and increase the average size of Active Set and reduce the average Drop Call rate. It was also found that Hata’s propagation model contributed significantly to improvements in system performance parameters compared to Okumura’s propagation model and Lee’s propagation model.

    Nephrology fellows need expertise navigating challenging conversations with patients throughout the course of advanced kidney disease. However, evidence shows that nephrologists receive inadequate training in this area. This study assessed the effectiveness of an educational quality improvement intervention designed to enhance fellows' communication with patients who have advanced kidney disease. Quality improvement project. Full-day annual workshops (2013-2014) using didactics, discussion, and practice with simulated patients. Content focused on delivering bad news, acknowledging emotion, discussing care goals in dialysis decision making when prognosis is uncertain, and addressing dialysis therapy withdrawal and end of life. Participants were first-year nephrology fellows from 2 Harvard-affiliated training programs (N=26). Study assessed the effectiveness of an intervention designed to enhance fellows' communication skills. Primary outcomes were changes in self-reported patient communication skills, attitudes, and behaviors related to discussing disease progression, prognostic uncertainty, dialysis therapy withdrawal, treatments not indicated, and end of life; responding to emotion; eliciting patient goals and values; and incorporating patient goals into recommendations. Surveys measured prior training, pre- and postcourse perceived changes in skills and values, and reported longer term (3-month) changes in communication behaviors, using both closed- and open-ended items. Response rates were 100% (pre- and postsurveys) and 68% (follow-up). Participants reported improvement in all domains, with an overall mean increase of 1.1 (summed average scores: precourse, 2.8; postcourse, 3.9 [1-5 scale; 5 = "extremely well prepared"]; Pskills taught, such as "Ask-Tell-Ask" and using open-ended questions. Self-reported data may overestimate actual changes; small sample size and the programs' affiliation with a single medical school may limit generalizability. A day

    This report describes an evaluation of NRC generic communications with industry concerning safety related issues of commercial nuclear power plandts. The analysis builds on the findings presented in the 1986 Office of Analysis and Evaluation of Operational Data (AEOD) Special Study Report, ''An Overview of Nuclear Power Plant Operating Experience Feedback Programs'' (AEOD/S602). The primary objective of the report is to present practical recommendations for improving NRC's documents and generic communications system. The report is based upon a systematic review and evaluation of NRC and industry operating experience documents. It also includes an analysis of interviews with licensee personnel at five utilities and their nuclear power plants. NRC regional and headquarters managers and staff were also interviewed for the study. NRC and licensee personnel interviewed are generally satisfied with the current NRC-industry communications system; however, several problems and potential solutions to those problems are identified in this study. The report makes seven major recommendations for improvement in the effectiveness of NRC-industry generic communications about nuclear power plant operating experience

    In Europe today, institutions, media and the general public exchange information about ionizing radiation and associated risks. However, communication about ionising radiation with the general public has to be further improved, as has been previously highlighted by international responses to the 2011 accident in Japan. This article reports the main activities and findings in this field from the following three FP7 projects: EAGLE, PREPARE and OPERRA and discussed by a broad spectrum of stakeholders at the conference RICOMET 2015. These projects, among other aims, also investigate how communication about ionising radiation in different fields could be improved and harmonised, how radiological risks are perceived, how to encourage ethical considerations in all fields of nuclear applications and what kind of transdisciplinary research is needed. The projects relate to several domains; the first relates to education, training and communication, the second to nuclear emergency preparedness and response, and the third to research and development in the radiation protection field. Incorporation of stakeholder engagement activities such as the RICOMET conference broadens social and ethical aspects and takes them into account during coordination activities as well as during core scientific and nuclear research and development performed in the projects. These activities offered opportunities for moving closer to a citizen-centred ideal of risk communication in particular and nuclear research and development in general.

    More attention has been paid to ternary Ti-Ni-Hf high-temperature shape memory alloys (SMAs) due to their high phase transformation temperatures, good thermal stability and low cost. However, the Ti-Ni-Hf alloys have been found to have low ductility and only about 3% shape memory effect and these have hampered their applications. It is well known that there are three methods to improve the shape memory properties of high-temperature SMAs: (a) cold rolling + annealing; (b) adding another element to the alloy; (c) aging. These methods are not suitable to improve the properties of Ti-Ni-Hf alloys. In this paper, a method of conditioning Ni-rich Ti-Ni-Hf alloys as high-temperature SMAs by aging is presented. For Ni-rich Ti 80-x Ni x Hf 20 alloys (numbers indicate at.%) the phase transformation temperatures are on average increased by more than 100 K by aging at 823 K for 2 h. Especially for those alloys with Ni contents less than 50.6 at.%, the martensitic transformation start temperatures (M s ) are higher than 473 K after aging. Transmission electron microscopy shows the presence of (Ti + Hf) 3 Ni 4 precipitates after aging. Compared with the precipitation of Ti 3 Ni 4 particles in Ni-rich Ti-Ni alloys, the precipitation of (Ti + Hf) 3 Ni 4 particles in Ni-rich Ti-Ni-Hf alloys needs higher temperatures and longer times

    To improve communication during daily cardiac ICU multidisciplinary rounds. Quality improvement methodology. Twenty-five-bed cardiac ICUs in an academic free-standing pediatric hospital. All patients admitted to the cardiac ICU. Implementation of visual display of patient daily goals through a write-down and read-back process. The Rounds Effectiveness Assessment and Communication Tool was developed based on the previously validated Patient Knowledge Assessment Tool to evaluate comprehension of patient daily goals. Rounds were assessed for each patient by the bedside nurse, nurse practitioner or fellow, and attending physician, and answers were compared to determine percent agreement per day. At baseline, percent agreement for patient goals was only 62%. After initial implementation of the daily goal write-down/read-back process, which was written on paper by the bedside nurse, the Rounds Effectiveness Assessment and Communication Tool survey revealed no improvement. With adaptation of the intervention so goals were written on whiteboards for visual display during rounds, the percent agreement improved to 85%. Families were also asked to complete a survey (1-6 Likert scale) of their satisfaction with rounds and understanding of daily goals before and after the intervention. Family survey results improved from a mean of 4.6-5.7. Parent selection of the best possible score for each question was 19% at baseline and 75% after the intervention. Visual display of patient daily goals via a write-down/read-back process improves comprehension of goals by all team members and improves parent satisfaction. The daily goal whiteboard facilitates consistent development of a comprehensive plan of care for each patient, fosters goal-directed care, and provides a checklist for providers and parents to review throughout the day.

    Achieving health literacy is a critical step to improving health outcomes and the health of a nation. However, there is a lack of research on health literacy in low-resource countries, where maternal health outcomes are at their worst. To examine the usefulness and feasibility of providing focused antenatal care (FANC) in a group setting using picture cards to improve patient-provider communication, patient engagement, and improve health literacy. An exploratory, mixed methods design was employed to gather pilot data using the Health Literacy Skills Framework. A busy urban district hospital in the Ashanti Region of Ghana was used to gather data during 2014. A facility-driven convenience sample of midwives (n=6) aged 18 years or older, who could speak English or Twi, and had provided antenatal care at the participating hospital during the previous year prior to the start of the study participated in the study. Data were collected using pre-test and post-test surveys, completed three months after the group FANC was implemented. A semi-structured focus group was conducted with four of the participating midwives and the registered nurse providing support and supervision for the study (n=5) at the time of the post-test. Data were analyzed concurrently to gain a broad understanding of patient communication, engagement, and group FANC. There were no significant differences in the mean communication (t(df=3)=0.541, p=0.626) and engagement (t(df=3)=-0.775, p=0.495) scores between the pre- and post-test. However, the focus group revealed the following themes: (a) improved communication through the use of picture cards; (b) enhanced information sharing and peer support through the facilitated group process and; and (c) an improved understanding of patient concerns. The improved communication noted through the use of picture cards and the enhanced information sharing and peer support elicited through the group FANC undoubtedly provided patients with additional tools to invoke

    Abstract—In a recent paper [1] the filter bank multicarrier spread spectrum (FB-MC-SS) waveform was proposed for wideband spread spectrum HF communications. A significant benefit of this waveform is robustness against narrow and partial band interference. Simulation results in [1] demonstrated good performance in a wideband HF channel over a wide range of conditions. In this paper we present a theoretical analysis of the bit error probably for this system. Our analysis tailors the results from [2] where BER performance was analyzed for maximum ration combining systems that accounted for correlation between subcarriers and channel estimation error. Equations are give for BER that closely match the simulated performance in most situations.

    This report describes the findings of an investigation into selected communication means for control room personnel in nuclear power stations. The study can be seen as a contribution to the systematic analysis of major problem areas which were identified in the general study 'Human factors in the nuclear power plant'. The subjects under investigation were the 'Shift book', 'Simulation book', and 'Technical and organisational changes and their records'. It was intended to analyse both the communication, processes and the associated written documentation in order to determine areas for potential improvement and possibilities for standardization. Information was obtained by interviewing shift members and their supervisors, by general observation, and by compilation and evaluation of the extensive dokumentation. Assessment criteria were developed on a scientific basis and in the course of the investigation, in particular from ergonomic findings, as well as from standards and regulations and comparison between the plants. General practical suggestions were developed for the improvement of the communication forms and the formal design of the documents and their contents. The transfer of the recommendations to practical use in the plants presupposes the consideration of plant-specific frames of reference. The report includes a compilation and listing of suggestions for improvement in topical subdivisions. (orig.) [de

    The transfer of care for hospitalized patients between inpatient physicians is routinely mediated through written and verbal communication or "sign-out". This study aims to describe how communication failures during this process can lead to patient harm. In interviews employing critical incident technique, first year resident physicians (interns) described (1) any adverse events or near misses due to suboptimal preceding patient sign-out; (2) the worst event due to suboptimal sign-out in which they were involved; and (3) suggestions to improve sign-out. All data were analyzed and categorized using the constant comparative method with independent review by three researchers. Twenty six interns caring for 82 patients were interviewed after receiving sign-out from another intern. Twenty five discrete incidents, all the result of communication failures during the preceding patient sign-out, and 21 worst events were described. Inter-rater agreement for categorization was high (kappa 0.78-1.00). Omitted content (such as medications, active problems, pending tests) or failure-prone communication processes (such as lack of face-to-face discussion) emerged as major categories of failed communication. In nearly all cases these failures led to uncertainty during decisions on patient care. Uncertainty may result in inefficient or suboptimal care such as repeat or unnecessary tests. Interns desired thorough but relevant face-to-face verbal sign-outs that reviewed anticipated issues. They preferred legible, accurate, updated, written sign-out sheets that included standard patient content such as code status or active and anticipated medical problems. Communication failures during sign-out often lead to uncertainty in decisions on patient care. These may result in inefficient or suboptimal care leading to patient harm.

    Limited disease knowledge is frequently the cause of disease-related anxiety in myocardial infarction patients. The ability to communicate effectively serves multiple purposes in the professional nursing practice. By communicating effectively with myocardial infarction patients, nurses may help reduce their anxiety by keeping them well informed about their disease and teaching them self-care strategies. This research evaluates the communication skills of nurses following scenario-based simulation education in the context of communication with myocardial infarction patients. This study used an experimental design and an educational intervention. The target population comprised nurses of medicine (clinical qualified level N to N2 for nursing) working at a municipal hospital in Taipei City, Taiwan. A total 122 participants were enrolled. Stratified block randomization divided participants into an experimental group and a control group. The experimental group received clinical scenario-based simulation education for communication. The control group received traditional class-based education for communication. Both groups received a pre-test and a Communication Skills Checklist post-test assessment. Results were analyzed using SPSS 17.0 for Windows software. A t-test showed significant increases in communication skills (p skills following the education intervention. The results indicate that clinical scenario-based simulation education for communication is significantly more effective than traditional class-based education in enhancing the ability of nurses to communicate effectively with myocardial infarction patients.

    Patients often do not fully understand medical information discussed during office visits. This can result in lack of adherence to recommended treatment plans and poorer health outcomes. We developed and implemented a program utilizing an encounter form, which provides structure to the medical interaction and facilitates bidirectional communication and informed decision-making. We conducted a prospective quality improvement intervention at a large tertiary-care academic medical center utilizing the encounter form and studied the effect on patient satisfaction, understanding and confidence in communicating with physicians. The intervention included 108 patients seen by seven physicians in five sub-specialties. Ninety-eight percent of patients were extremely satisfied (77%) or somewhat satisfied (21%) with the program. Ninety-six percent of patients reported being involved in decisions about their care and treatments as well as high levels of understanding of medical information that was discussed during visit. Sixty-nine percent of patients reported that they shared the encounter form with their families and friends. Patients' self-confidence in communicating with their doctors increased from a score of 8.1 to 8.7 post-intervention (P-value = 0.0018). When comparing pre- and post-intervention experiences, only 38% of patients felt that their problems and questions were adequately addressed by other physicians' pre-intervention, compared with 94% post-intervention. We introduced a program to enhance physician-patient communication and found that patients were highly satisfied, more informed and more actively involved in their care. This approach may be an easily generalizable approach to improving physician-patient communication at outpatient visits.

    Full Text Available Abstract Background Effective provider-parent communication can improve childhood vaccination uptake and strengthen immunisation services in low- and middle-income countries (LMICs. Building capacity to improve communication strategies has been neglected. Rigorous research exists but is not readily found or applicable to LMICs, making it difficult for policy makers to use it to inform vaccination policies and practice. The aim of this project is to build research knowledge and capacity to use evidence-based strategies for improving communication about childhood vaccinations with parents and communities in LMICs. Methods and design This project is a mixed methods study with six sub-studies. In sub-study one, we will develop a systematic map of provider-parent communication interventions for childhood vaccinations by screening and extracting data from relevant literature. This map will inform sub-study two, in which we will develop a taxonomy of interventions to improve provider-parent communication around childhood vaccination. In sub-study three, the taxonomy will be populated with trial citations to create an evidence map, which will also identify how evidence is linked to communication barriers regarding vaccination. In the project's fourth sub-study, we will present the interventions map, taxonomy, and evidence map to international stakeholders to identify high-priority topics for systematic reviews of interventions to improve parent-provider communication for childhood vaccination. We will produce systematic reviews of the effects of high-priority interventions in the fifth sub-study. In the sixth and final sub-study of the project, evidence from the systematic reviews will be translated into accessible formats and messages for dissemination to LMICs. Discussion This project combines evidence mapping, conceptual and taxonomy development, priority setting, systematic reviews, and knowledge transfer. It will build and share concepts, terms

    Modern dielectrics in combination with appropriate metal electrodes have a great potential to solve many difficulties associated with continuing miniaturization process in the microelectronic industry. One significant branch of microelectronics incorporates dynamic random access memory (DRAM) market. The DRAM devices scaled for over 35 years starting from 4 kb density to several Gb nowadays. The scaling process led to the dielectric material thickness reduction, resulting in higher leakage current density, and as a consequence higher power consumption. As a possible solution for this problem, alternative dielectric materials with improved electrical and material science parameters were intensively studied by many research groups. The higher dielectric constant allows the use of physically thicker layers with high capacitance but strongly reduced leakage current density. This work focused on deposition and characterization of thin insulating layers. The material engineering process was based on Si cleanroom compatible HfO 2 thin films deposited on TiN metal electrodes. A combined materials science and dielectric characterization study showed that Ba-added HfO 2 (BaHfO 3 ) films and Ti-added BaHfO 3 (BaHf 0.5 Ti 0.5 O 3 ) layers are promising candidates for future generation of state-of-the-art DRAMs. In especial a strong increase of the dielectric permittivity k was achieved for thin films of cubic BaHfO 3 (k∝38) and BaHf 0.5 Ti 0.5 O 3 (k∝90) with respect to monoclinic HfO 2 (k∝19). Meanwhile the CET values scaled down to 1 nm for BaHfO 3 and ∝0.8 nm for BaHf 0.5 Ti 0.5 O 3 with respect to HfO 2 (CET=1.5 nm). The Hf 4+ ions substitution in BaHfO 3 by Ti 4+ ions led to a significant decrease of thermal budget from 900 C for BaHfO 3 to 700 C for BaHf 0.5 Ti 0.5 O 3 . Future studies need to focus on the use of appropriate metal electrodes (high work function) and on film deposition process (homogeneity) for better current leakage control. (orig.)

    There are many islands (or reefs) in the South China Sea. The hydrological properties (currents and waves) around the islands are highly spatially variable compared to those of coastal region of mainland, because the shorelines are more complex with much smaller scale, and the topographies are step-shape with a much sharper slope. The currents and waves with high spatial variations may destroy the buildings or engineering on shorelines, or even influence the structural stability of reefs. Therefore, it is necessary to establish monitoring systems to obtain the high-resolution hydrological information. This study propose a plan for developing a hydrological monitoring system based on HF radar on the shoreline of a typical island in the southern South China Sea: firstly, the HF radar are integrated with auxiliary equipment (such as dynamo, fuel tank, air conditioner, communication facilities) in a container to build a whole monitoring platform; synchronously, several buoys are set within the radar visibility for data calibration and validation; and finally, the current and wave observations collected by the HF radar are assimilated with numerical models to obtain long-term and high-precision reanalysis products. To test the feasibility of this plan, our research group has built two HF radar sites at the western coastal region of Guangdong Province. The collected data were used to extract surface current information and assimilated with an ocean model. The results show that the data assimilation can highly improve the surface current simulation, especially for typhoon periods. Continuous data with intervals between 6 and 12 hour are the most suitable for ideal assimilations. On the other hand, the test also reveal that developing similar monitoring system on island environments need advanced radars that have higher resolutions and a better performance for persistent work.

    Communication in the intensive care unit (ICU) is an important component of quality ICU care. In this report, we evaluate the long-term effects of a quality improvement (QI) initiative, based on the VALUE communication strategy, designed to improve communication with family members of critically ill patients. We implemented a multifaceted intervention to improve communication in the ICU and measured processes of care. Quality improvement components included posted VALUE placards, templated progress note inclusive of communication documentation, and a daily rounding checklist prompt. We evaluated care for all patients cared for by the intensivists during three separate 3 week periods, pre, post, and 3 years following the initial intervention. Care delivery was assessed in 38 patients and their families in the pre-intervention sample, 27 in the post-intervention period, and 41 in follow-up. Process measures of communication showed improvement across the evaluation periods, for example, daily updates increased from pre 62% to post 76% to current 84% of opportunities. Our evaluation of this quality improvement project suggests persistence and continued improvements in the delivery of measured aspects of ICU family communication. Maintenance with point-of-care-tools may account for some of the persistence and continued improvements. Copyright © 2014 Elsevier Inc. All rights reserved.

    Despite the high burden and poor rates of treatment associated with mental illness and substance use disorders, public support for allocating resources to improving treatment for these disorders is low. A growing body of research suggests that effective policy communication strategies can increase public support for policies benefiting people with these conditions. In October 2015, the Center for Mental Health and Addiction Policy Research at Johns Hopkins University convened an expert forum to identify what is currently known about the effectiveness of such policy communication strategies and produce recommendations for future research. One of the key conclusions of the forum was that communication strategies using personal narratives to engage audiences have the potential to increase public support for policies benefiting persons with mental illness or substance use disorders. Specifically, narratives combining personal stories with depictions of structural barriers to mental illness and substance use disorder treatment can increase the public's willingness to invest in the treatment system. Depictions of mental illness and violence significantly increase public stigma toward people with mental illness and are no more effective in increasing willingness to invest in mental health services than nonstigmatizing messages about structural barriers to treatment. Future research should prioritize development and evaluation of communication strategies to increase public support for evidence-based substance use disorder policies, including harm reduction policies-such as needle exchange programs-and policies expanding treatment.

    This study examined the effect of a theoretically grounded, tailored education-coaching intervention to help patients more effectively discuss their pain-related questions, concerns, and preferences with physicians. Grounded in social-cognitive and communication theory, a tailored education-coaching (TEC) intervention was developed to help patients learn pain management and communication skills. In a RCT, 148 cancer patients agreed to have their consultations audio-recorded and were assigned to the intervention or a control group. The recordings were used to code for patients' questions, acts of assertiveness, and expressed concerns and to rate the quality of physicians' communication. Patients in the TEC group discussed their pain concerns more than did patients in the control group. More active patients also had more baseline pain and interacted with physicians using participatory decision-making. Ratings of physicians' information about pain were higher when patients talked more about their pain concerns. The study demonstrates the efficacy of a theoretically grounded, coaching intervention to help cancer patients talk about pain control. Coaching interventions can be effective resources for helping cancer patients communicate about their pain concerns if they are theoretically grounded, can be integrated within clinical routines, and lead to improve health outcomes.

    Factors influencing access to health care among people with disabilities (PWD) include: attitudes of health care providers and the public, physical barriers, miscommunication, income level, ethnic/minority status, insurance coverage, and lack of information tailored to PWD. Reducing health care disparities in a population with complex needs requires implementation at the primary, secondary and tertiary levels. This review article discusses common barriers to health care access from the patient and provider perspective, particularly focusing on communication barriers and how to address and ameliorate them. Articles utilized in this review were published from 2005 to present in MEDLINE and CINAHL and written in English that focused on people with disabilities. Topics searched for in the literature include: disparities and health outcomes, health care dissatisfaction, patient-provider communication and access issues. Ineffective communication has significant impacts for PWD. They frequently believe that providers are not interested in, or sensitive to their particular needs and are less likely to seek care or to follow up with recommendations. Various strategies for successful improvement of health outcomes for PWD were identified including changing the way health care professionals are educated regarding disabilities, improving access to health care services, and enhancing the capacity for patient centered care.

    To improve communication between doctors and nurses after hours, by developing a tool to display ward tasks, allowing staff to prioritise their work, without constant interruption from pagers (beepers). Middlemore Hospital, a large metropolitan 800-bed hospital in Auckland, New Zealand. Introduction of computerised system (Task Manager) to identify, allocate and complete after-hours tasks. In the first 6 months 21,000 tasks have been completed in Task Manager. Paging of junior doctors has decreased by over 30% and there is broad acceptance of the tool by both nursing and medical staff. Task Manager has collected real-time data on the type of after hours tasks (nearly 50% are phlebotomy-related tasks), busy times of the day (1600 hours to 2400 hours) and who is performing most of the tasks. Task Manager is a simple yet powerful tool for prioritising routine tasks after hours. It allows staff to quickly create tasks, and communicate effectively with other members of the team. It has reduced the frequency of junior doctors paging so that they can continue their work with fewer interruptions. Whilst it was introduced to improve effective communication after hours, it has become apparent that there are multiple 'tasks' that are ordered in a multitude of ways in our hospital and many could be served by Task Manager.

    Close collaboration between specialists from diverse backgrounds and working in different scientific domains is an effective strategy to overcome challenges in areas that interface between biology, chemistry, physics and engineering. Communication in such collaborations can itself be challenging.  Even when projects are successfully concluded, resulting publications - necessarily multi-authored - have the potential to be disjointed. Few, both in the field and outside, may be able to fully understand the work as a whole. This needs to be addressed to facilitate efficient working, peer review, accessibility and impact to larger audiences. We are an interdisciplinary team working in a nascent scientific area, the repurposing of DNA as a storage medium for digital information. In this note, we highlight some of the difficulties that arise from such collaborations and outline our efforts to improve communication through a glossary and a controlled vocabulary and accessibility via short plain-language summaries. We hope to stimulate early discussion within this emerging field of how our community might improve the description and presentation of our work to facilitate clear communication within and between research groups and increase accessibility to those not familiar with our respective fields - be it molecular biology, computer science, information theory or others that might become relevant in future. To enable an open and inclusive discussion we have created a glossary and controlled vocabulary as a cloud-based shared document and we invite other scientists to critique our suggestions and contribute their own ideas.

    2010-03-01

    Chronic obstructive pulmonary disease (COPD) and chronic heart failure (HF) are common clinical conditions that share tobacco as a risk factor. Our aim was to evaluate the prognostic impact of COPD on HF patients. The Norwegian Heart Failure Registry was used. The study included 4132 HF patients (COPD, n = 699) from 22 hospitals (mean follow-up, 13.3 months). COPD patients were older, more often smokers and diabetics, less often on beta-blockers and had a higher heart rate. They were more often in New York Heart Association (NYHA) Class III or IV (COPD, 63%; no COPD, 51%), although left ventricular ejection fraction (LVEF) distribution was similar. COPD independently predicted death (adjusted hazard ratio [HR], 1.188; 95% CI: 1.015 to 1.391; P = 0.03) along with age, creatinine, NYHA Class III/IV (HR, 1.464; 95% CI: 1.286 to 1.667) and diabetes. beta-blockers at baseline were associated with improved survival in patients with LVEF < or =40% independently of COPD. COPD is associated with a poorer survival in HF patients. COPD patients are overrated in terms of NYHA class in comparison with patients with similar LVEF. Nonetheless, NYHA class remains the strongest predictor of death in these patients. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    The variation of positron lifetime and oxygen stoichiometry as a function of quench temperature has been measured in undoped and 0.5at%, 0.75at%, and 1.0 at% Hf doped YBCO. In both the undoped and Hf doped samples, the lifetime decreases and the oxygen content increases as the quench temperature is lowered from 900degC to 300degC. The lifetime in the tetragonal phase (900degC) decreases with the increase in Hf content, whereas in the orthorhombic phase (450degC) it increases. The difference in lifetime between the tetragonal and orthorhombic phases decreases with the increase in the Hf content. These trends are discussed in terms of the influence of Hf doping on the oxygen content and the positron density distribution in YBCO

    Effective communication between providers and patients and their surrogates in the intensive care unit (ICU) is crucial for delivery of high-quality care. Despite the identification of communication as a key education focus by the American Board of Internal Medicine, little emphasis is placed on teaching trainees how to effectively communicate in the ICU. Data are conflicting on the best way to teach residents, and institutions vary on their emphasis of communication as a key skill. There needs to be a cultural shift surrounding the education of medical residents in the ICU: communication must be treated with the same emphasis, precision, and importance as placing a central venous catheter in the ICU. We propose that high-stakes communications between physicians and patients or their surrogates must be viewed as a medical procedure that can be taught, assessed, and quality controlled. Medical residents require training, observation, and feedback in specific communication skill sets with the goal of achieving mastery. It is only through supervised training, practice in real time, observation, and feedback that medical residents can become skillful practitioners of communication in the ICU.

    We have redesigned a tried-and-true laboratory exercise into an inquiry-based team activity exploring microbial growth control, and implemented this activity as the basis for preparing a scientific poster in a large, multi-section laboratory course. Spanning most of the semester, this project culminates in a poster presentation of data generated from a student-designed experiment. Students use and apply the scientific method and improve written and verbal communication skills. The guided inquiry format of this exercise provides the opportunity for student collaboration through cooperative learning. For each learning objective, a percentage score was tabulated (learning objective score = points awarded/total possible points). A score of 80% was our benchmark for achieving each objective. At least 76% of the student groups participating in this project over two semesters achieved each learning goal. Student perceptions of the project were evaluated using a survey.

    We have redesigned a tried-and-true laboratory exercise into an inquiry-based team activity exploring microbial growth control, and implemented this activity as the basis for preparing a scientific poster in a large, multi-section laboratory course. Spanning most of the semester, this project culminates in a poster presentation of data generated from a student-designed experiment. Students use and apply the scientific method and improve written and verbal communication skills. The guided inquiry format of this exercise provides the opportunity for student collaboration through cooperative learning. For each learning objective, a percentage score was tabulated (learning objective score = points awarded/total possible points). A score of 80% was our benchmark for achieving each objective. At least 76% of the student groups participating in this project over two semesters achieved each learning goal. Student perceptions of the project were evaluated using a survey. Nearly 90% of participating students felt they had learned a great deal in the areas of formulating a hypothesis, experimental design, and collecting and analyzing data; 72% of students felt this project had improved their scientific writing skills. In a separate survey, 84% of students who responded felt that peer review was valuable in improving their final poster submission.

    The students' communication skills in English have improved after introducing Extensive Reading courses into the curriculum of Electrical and Electronic Engineering Department. The students' average TOEIC scores, which used to be far lower than the ones of students in other educational institutions, have increased in recent two years. The students who used to avoid learning English have welcomed extensive reading of graded readers for foreign learners and books for native children of English. This is because the extensive reading causes less stress and it is enjoyable. The students who have read more than 0.2 million words of English texts have faster reading speed and more confidence in reading. They seem to change their reading style from English-to-Japanese translation (and comprehension in Japanese) to direct comprehension in English. Their listening comprehension is also improved. Extensive reading is an effective educational method to improve English communication skills of engineering students, and it also becomes a useful method of continuous education for engineers in need of improving their skills.

  15. The Research on Improved Companding Transformation for Reducing PAPR in Underwater Acoustic OFDM Communication System

    2016-01-01

    Full Text Available To solve the problem of the high peak-to-average power ratio (PAPR in Orthogonal Frequency Division Multiplexing (OFDM for the underwater acoustic communication system, the paper offers a method of reducing PAPR which combines the amplitude limiting and the improved nonlinear transformation. Traditional amplitude limiting technique can reduce PAPR in OFDM system effectively, at the cost of reducing the bit error rate (BER. However the companding transformation has far less computation complexity than SLM or PTS technologies and can improve the BER performance compared to the amplitude limiting technique simultaneously. The paper combines these two kinds of techniques, takes full use of advantages of the two method, and puts forward a low-complexity scheme choosing parameters that are more appropriate to the underwater acoustic field, with the result of improved BER performance even in lower SNR. Both simulation and experiment results show that the new method which combines clipping and companding transformation can effectively reduce the PAPR in the underwater acoustic OFDM communication system and improve the BER performance simultaneously.

    2016-12-01

    In order to better communicate relevant scientific knowledge to policy- and decision makers, Stockholm University and the Baltic Sea 2020 Foundation partnered to create Baltic Eye in 2014. Seven scientists and two communicators constitute the core team of this initiative. The team integrates communications with scientific analysis and synthesis of Baltic Sea environmental issues. In the past year, the team has focused on two main issues: fisheries management and microplastics. Baltic Sea cod stocks are in poor condition, with large numbers of small individuals. Baltic Eye recommended improvements to the European Union's multiannual fisheries plan to better align with ecosystem-based management principles: prioritization of cod stock recovery, greater consideration of natural variability of temperature and salinity (which affects cod spawning success), and inclusion of mechanisms to adjust quotas in the event of major environmental changes. Communications included policy briefs and debate articles targeted to the European Parliament, national government ministries, and non-governmental organizations. Every year, up to 40 tons of microplastics from personal care products are released in the Baltic Sea catchment. Baltic Eye raised awareness of the issue and made recommended ways to reduce microplastic emissions. Communications included a public presentation to journalists, politicians, and representatives of Swedish government ministries. A policy brief was provided Heads of Delegates of the Helsinki Commission (for protrection of the Baltic Sea environment) in advance of a meeting to develop a plan of action for marine litter. Researchers were interviewed for radio, TV, and print media in Sweden, Finland, and Germany. Next steps are to engage with multinational manufacturers about plans to voluntarily phase out microplastics in personal care products.

    Teamwork and communication often play a role in adverse clinical events. Due to the multidisciplinary and time-sensitive nature of trauma care, the effects of teamwork and communication can be especially pronounced in the treatment of the acutely injured patient. Our hypothesis was that an in situ trauma simulation (ISTS) program (simulating traumas in the trauma bay with all members of the trauma team) could be implemented in an emergency department (ED) and that this would improve teamwork and communication measured in the clinical setting. This was an observational study of the effect of an ISTS program on teamwork and communication during trauma care. The authors observed a convenience sample of 39 trauma activations. Cases were selected by their presenting to the resuscitation bay of a Level I trauma center between 09:00 and 16:00, Monday through Thursday, during the study period. Teamwork and communication were measured using the previously validated Clinical Teamwork Scale (CTS). The observers were three Trauma Nursing Core Course certified RNs trained on the CTS by observing simulated and actual trauma cases and following each of these cases with a discussion of appropriate CTS scores with two certified Advanced Trauma Life Support instructors/emergency physicians. Cases observed for measurement were scored in four phases: 1) preintervention phase (baseline); 2) didactic-only intervention, the phase following a lecture series on teamwork and communication in trauma care; 3) ISTS phase, real trauma cases scored during period when weekly ISTSs were performed; and 4) potential decay phase, observations following the discontinuation of the ISTSs. Multirater agreement was assessed with Krippendorf's alpha coefficient; agreement was excellent (mean agreement = 0.92). Nonparametric procedures (Kruskal-Wallis) were used to test the hypothesis that the scores observed during the various phases were different and to compare each individual phase to baseline scores

  18. Improved achievable secrecy rate of visible light communication with cooperative jamming

    2016-02-25

    In this paper we study the problem of securing a visible light communication (VLC) link against passive eavesdropping, with the help of a (friendly) jammer. Differently from radio frequency (RF) communications, VLC imposes a peak amplitude constraint on the input distribution which renders Gaussian inputs not admissible. We provide an achievable secrecy rate that improves upon a recently established one in a concurrent work by Mostafa and Lampe. Our scheme follows from both the secrecy capacity result by Wyner and the artificial noise scheme by Goel and Negi, but using truncated Gaussian input distributions instead of uniform ones. Via numerical results, we show that our secrecy rate outperforms the concurrent rate in different settings. © 2015 IEEE.

    Liu, Zhi-Hao; Chen, Han-Wu

    2018-02-01

    As we know, the information leakage problem should be avoided in a secure quantum communication protocol. Unfortunately, it is found that this problem does exist in the large payload bidirectional quantum secure direct communication (BQSDC) protocol (Ye Int. J. Quantum. Inf. 11(5), 1350051 2013) which is based on entanglement swapping between any two Greenberger-Horne-Zeilinger (GHZ) states. To be specific, one half of the information interchanged in this protocol is leaked out unconsciously without any active attack from an eavesdropper. Afterward, this BQSDC protocol is revised to the one without information leakage. It is shown that the improved BQSDC protocol is secure against the general individual attack and has some obvious features compared with the original one.

    Human papillomavirus (HPV) vaccination rates lag behind vaccination rates for other adolescent vaccines; a bundled intervention may improve HPV vaccination rates. Our objective is to evaluate the impact of quality improvement (QI) training plus a bundled practice-based intervention (provider prompts plus communication skills training plus performance feedback) on improving HPV vaccinations in pediatric resident continuity clinics. Staff and providers in 8 resident clinics participated in a 12-month QI study. The intervention included training to strengthen provider communication about the HPV vaccine. Clinics also implemented provider prompts, received monthly performance feedback, and participated in learning collaborative calls. The primary outcome measure was eligible visits with vaccination divided by vaccine-eligible visits (captured HPV vaccination opportunities). Practices performed chart audits that were fed into monthly performance feedback on captured HPV vaccination opportunities. We used conditional logistic regression (conditioning on practice) to assess captured vaccination opportunities, with the time period of the study (before and after the QI intervention) as the independent variable. Overall, captured opportunities for HPV vaccination increased by 16.4 percentage points, from 46.9% to 63.3%. Special cause was demonstrated by centerline shift, with 8 consecutive points above the preintervention mean. On adjusted analyses, patients were more likely to receive a vaccine during, versus before, the intervention (odds ratio: 1.87; 95% confidence interval: 1.54-2.28). Captured HPV vaccination rates improved at both well-child and other visits (by 11.7 and 13.0 percentage points, respectively). A bundled intervention of provider prompts and training in communication skills plus performance feedback increased captured opportunities for HPV vaccination.

    Full Text Available Referral of patients to hospitals, specialists and other institutions is an essential part of primary health care. Patients are referred to specialists when investigation or therapeutic options are exhausted in primary care or when opinion or advice is needed from them. Referral has considerable implications for patients, health care system and health care costs. Good communication between primary and secondary care is essential for the smooth running of any health care system. Referral and reply letters are the sole means of communication between doctors most of the time and breakdown in communication could lead to poor continuity of care, delayed diagnoses, polypharmacy, increased litigation risk and unnecessary testing. A referral letter also helps to avoid patient dissatisfaction and loss of confidence in family physician. Studies of referral letters have reported that specialists are dissatisfied with their quality and content. Inclusion of letter writing skills in the medical curriculum, peer assessment and feedback have shown to improve the quality of referral letters. . Form letters have shown to enhance information content and communication in referral process. In Sri Lanka referral letters are usually hand written and frequent complaints are that these letters do not contain adequate information and retrieval of information is a problem due to poor legibility and clarity. Sometimes Primary care doctors refer patients to hospitals and specialists with only verbal instructions. To address these short comings this form letter was introduced. Based on the guidelines and systematic review of published articles, items of information to be included were decided. Printed forms of the letter are kept in the practice and the doctor has to just fill up relevant information under each heading. The objectives of introducing this structured referral letter was to improve the quality and standard of referral letters and save time for both general

    Several key medical and oncologic professional societies have endorsed the importance of physician communication as a quality improvement metric. Despite this clear message, there remain substantial barriers to communication skills training (CST) in oncologic specialties. Herein, we describe the major barriers to communications training and propose standardized patient (SP) programs as efficient and strategic starting points and as expansion opportunities for new and existing CSTs.

    Technical communicators are concerned that if they employ public relations (PR) techniques, they somehow compromise their work. They believe PR equates with type. However, to those of us in the field, PR means simply how people relate. Knowing PR techniques gives one a better understanding of human factors and interactions; using the techniques improves the chances for communication to occur. If technical communications are willing to learn PR techniques, they will gain strong tools to use to strengthen their messages.

  6. Enhancement of Endurance in HfO2-Based CBRAM Device by Introduction of a TaN Diffusion Blocking Layer

    KAUST Repository

    Chand, Umesh

    2017-08-05

    We propose a new method to improve resistive switching properties in HfO2 based CBRAM crossbar structure device by introducing a TaN thin diffusion blocking layer between the Cu top electrode and HfO2 switching layer. The Cu/TaN/HfO2/TiN device structure exhibits high resistance ratio of OFF/ON states without any degradation in switching during endurance test. The improvement in the endurance properties of the Cu/TaN/HfO2/TiN CBRAM device is thus attributed to the relatively low amount of Cu migration into HfO2 switching layer.

    Effective communication is critical to successful large-scale change. Yet, in our experience, communications strategies are not formally incorporated into quality improvement (QI) frameworks. The 1000 Lives Campaign ('Campaign') was a large-scale national QI collaborative that aimed to save an additional 1000 lives and prevent 50 000 episodes of harm in Welsh health care over a 2-year period. We use the Campaign as a case study to describe the development, application, and impact of a communications strategy embedded in a large-scale QI initiative. A comprehensive communications strategy guided communications work during the Campaign. The main aims of the communications strategy were to engage the hearts and minds of frontline National Health Service (NHS) staff in the Campaign and promote their awareness and understanding of specific QI interventions and the wider patient safety agenda. We used qualitative and quantitative measures to monitor communications outputs and assess how the communications strategy influenced awareness and knowledge of frontline NHS staff. The communications strategy facilitated clear and consistent framing of Campaign messages and allowed dissemination of information related to the range of QI interventions. It reaffirmed the aim and value of the Campaign to frontline staff, thereby promoting sustained engagement with Campaign activities. The communications strategy also built the profile of the Campaign both internally with NHS organizations across Wales and externally with the media, and played a pivotal role in improving awareness and understanding of the patient safety agenda. Ultimately, outcomes from the communications strategy could not be separated from overall Campaign outcomes. Systematic and structured communications can support and enhance QI initiatives. From our experience, we developed a 'communications bundle' consisting of six core components. We recommend that communications bundles be incorporated into existing QI

    radio systems. From the point of view Working Group 2 of the COST 296 Action, interest lies with effects associated

    with propagation via the ionosphere of signals within the HF band. Several aspects are covered in this paper:

    a The directions of arrival and times of flight of signals received over a path oriented along the trough have

    been examined and several types of propagation effects identified. Of particular note, combining the HF observations

    with satellite measurements has identified the presence of irregularities within the floor of the trough that

    result in propagation displaced from the great circle direction. An understanding of the propagation effects that

    result in deviations of the signal path from the great circle direction are of particular relevance to the operation

    of HF radiolocation systems.

    b Inclusion of the results from the above mentioned measurements into a propagation model of the northerly

    ionosphere (i.e. those regions of the ionosphere located poleward of, and including, the mid-latitude trough

    and the use of this model to predict the coverage expected from transmitters where the signals impinge on the

The electrical properties of metal-oxide-semiconductor capacitor fabricated with atomic-layer-deposited HfO{sub 2} film as a gate insulator were examined, and were compared with the similar devices with S passivation using a wet process – (NH{sub 4}){sub 2}S solution treatment. The H{sub 2}S annealing provided solid S passivation with the strong resistance against oxidation compared with the (NH{sub 4}){sub 2}S solution treatment, although S profiles at the interface of HfO{sub 2}/InP were similar. The decrease in electrical thickness of the gate insulator by S passivation was similar for both methods. However, the H{sub 2}S annealing was more effective to suppress interface state density near the valence band edge, because thermal energy during the annealing resulted in stronger S bonding and InP surface reconstruction. Moreover, the flatband voltage shift by constant voltage stress was lower for the device with H{sub 2}S annealing.

    In 2002, the Institute of Medicine called for the introduction of information technologies in health care settings to improve quality of care. We conducted a review of hospital charts of women who delivered before and after the implementation of an intranet-based computerized prenatal record in an inner-city practice. Our objective was to assess whether the use of this record improved communication among the outpatient office, the ultrasonography unit, and the labor floor. The charts of patients who delivered in August 2002 and August 2003 and received their prenatal care at the Comprehensive Family Care Center at Montefiore Medical Center were analyzed. Data collected included the presence of a copy of the prenatal record in the hospital chart, the date of the last documented prenatal visit, and documentation of any prenatal ultrasonograms performed. Forty-three charts in each group were available for review. The prenatal chart was absent in 16% of the charts of patients from August 2002 compared with only 2% in August 2003 charts (P intranet-based prenatal chart significantly improves communication among providers.

    To (1) develop a systems-level quality improvement tool targeting communicative access to information and decision-making for stroke patients with language disorders; and (2) evaluate the resulting tool-the Communicative Access Measures for Stroke (CAMS). Survey development and evaluation was in line with accepted guidelines and included item generation and reduction, survey formatting and composition, pretesting, pilot testing, and reliability assessment. Development and evaluation were carried out in hospital and community agency settings. The project used a convenience sample of 31 participants for the survey development, and 63 participants for the CAMS reliability study (broken down into 6 administrators/managers, 32 frontline staff, 25 participants with aphasia). Eligible participants invited to the reliability study included individuals from 45 community-based organizations in Ontario as well as 4400 individuals from communities of practice. Not applicable. Data were analyzed using kappa statistics and intraclass correlations for each item score on all surveys. A tool, the CAMS, comprising 3 surveys, was developed for health facilities from the perspectives of (1) administrators/policymakers, (2) staff/frontline health care providers, and (3) patients with aphasia (using a communicatively accessible version). Reliability for items on the CAMS-Administrator and CAMS-Staff surveys was moderate to high (kappa/intraclass correlation coefficients [ICCs], .54-1.00). As expected, reliability was lower for the CAMS-Patient survey, with most items having ICCs between 0.4 and 0.6. These findings suggest that CAMS may provide useful quality improvement information for health care facilities with an interest in improving care for patients with stroke and aphasia.

    The time delay and/or phase of a communication signal received by a digital communication receiver can be estimated based on a convolutional decoding operation that the communication receiver performs on the received communication signal. If the original transmitted communication signal has been spread according to a spreading operation, a corresponding despreading operation can be integrated into the convolutional decoding operation.

    To define the target domains of culture-improvement interventions, to assess the impact of these interventions on surgical culture and to determine whether culture improvements lead to better patient outcomes and improved healthcare efficiency. Healthcare systems are investing considerable resources in improving workplace culture. It remains unclear whether these interventions, when aimed at surgical care, are successful and whether they are associated with changes in patient outcomes. PubMed, Cochrane, Web of Science and Scopus databases were searched from January 1980 to January 2015. We included studies on interventions that aimed to improve surgical culture, defined as the interpersonal, social and organisational factors that affect the healthcare environment and patient care. The quality of studies was assessed using an adapted tool to focus the review on higher-quality studies. Due to study heterogeneity, findings were narratively reviewed. The 47 studies meeting inclusion criteria (4 randomised trials and 10 moderate-quality observational studies) reported on interventions that targeted three domains of culture: teamwork (n=28), communication (n=26) and safety climate (n=19); several targeted more than one domain. All moderate-quality studies showed improvements in at least one of these domains. Two studies also demonstrated improvements in patient outcomes, such as reduced postoperative complications and even reduced postoperative mortality (absolute risk reduction 1.7%). Two studies reported improvements in healthcare efficiency, including fewer operating room delays. These findings were supported by similar results from low-quality studies. The literature provides promising evidence for various strategies to improve surgical culture, although these approaches differ in terms of the interventions employed as well as the techniques used to measure culture. Nevertheless, culture improvement appears to be associated with other positive effects, including

    Full Text Available Advances in communication networks have enabled organization to send confidential data such as digital images over wireless networks. However, the broadcast nature of wireless communication channel has made it vulnerable to attack from eavesdroppers. We have developed a hybrid cryptography technique, and we present its application to digital images as a means of improving the security of digital image for transmission over wireless communication networks. The hybrid technique uses a combination of a symmetric (Data Encryption Standard and asymmetric (Rivest Shamir Adleman cryptographic algorithms to secure data to be transmitted between different nodes of a wireless network. Three different image samples of type jpeg, png and jpg were tested using this technique. The results obtained showed that the hybrid system encrypt the images with minimal simulation time, and high throughput. More importantly, there is no relation or information between the original images and their encrypted form, according to Shannon’s definition of perfect security, thereby making the system much more secure.

    2013-07-01

    The purpose of the article is to describe the experience of selecting, developing, and implementing a pharmacy department intranet site with commentary regarding application to other institutions. Clinical practitioners and supporting staff need an effective, efficient, organized, and user-friendly communication tool to utilize and relay information required to optimize patient care. To create a functional and user-friendly department intranet site, department leadership and staff should be involved in the process from selection of product through implementation. A product that supports both document storage management and communication delivery and has the capability to be customized to provide varied levels of site access is desirable. The designation of an intranet site owner/developer within the department will facilitate purposeful site design and site maintenance execution. A well-designed and up-to-date site along with formal end-user training are essential for staff adoption and continued utilization. Development of a department intranet site requires a considerable time investment by several members of the department. The implementation of an intranet site can be an important step toward achieving improved communications. Staff utilization of this resource is key to its success.

    Modern medical management requires constant quality improvement of the various instruments used for surgical procedures. Higher quality, less complicated handling, and reduced maintenance are all desirable qualities. However, any improvements in instrumentation require that surgeons must clearly understand the application of the device by adherence to the manufacturer's instructions. The weakness of this one-way information flow depends on the low interest among medical personnel for post-purchase reassessment. Service industries have research departments to investigate the post-purchase behavior of customers, and service recovery is considered essential to retain customers after service failure. All service providers can suffer service failures, and even the best providers may make errors in delivering service. Such an approach has been increasingly adopted in the risk management at medical institutions. We report our clinical trials of the post-purchase reassessment and product improvement of surgical instrumentation. Medical personnel reassessed the use of a newly developed endoscope holder based on the manufacturer's manual and made recommendations for possible improvements, which were examined by the manufacturer. Simple but important improvement was achieved for reducing the instability and uncertainty of instrument fixation. This bi-directional post-purchase communication between medical personnel and manufacturers can improve risk management in medical institutions.

    This article discusses the speaker identification for the improvement of the security communication between law enforcement units. The main task of this research was to develop the text-independent speaker identification system which can be used for real-time recognition. This system is designed for identification in the open set. It means that the unknown speaker can be anyone. Communication itself is secured, but we have to check the authorization of the communication parties. We have to decide if the unknown speaker is the authorized for the given action. The calls are recorded by IP telephony server and then these recordings are evaluate using classification If the system evaluates that the speaker is not authorized, it sends a warning message to the administrator. This message can detect, for example a stolen phone or other unusual situation. The administrator then performs the appropriate actions. Our novel proposal system uses multilayer neural network for classification and it consists of three layers (input layer, hidden layer, and output layer). A number of neurons in input layer corresponds with the length of speech features. Output layer then represents classified speakers. Artificial Neural Network classifies speech signal frame by frame, but the final decision is done over the complete record. This rule substantially increases accuracy of the classification. Input data for the neural network are a thirteen Mel-frequency cepstral coefficients, which describe the behavior of the vocal tract. These parameters are the most used for speaker recognition. Parameters for training, testing and validation were extracted from recordings of authorized users. Recording conditions for training data correspond with the real traffic of the system (sampling frequency, bit rate). The main benefit of the research is the system developed for text-independent speaker identification which is applied to secure communication between law enforcement units.

    Researchers and clinicians are concerned about the impact of electronic health record use and patient-centered communication. Training about patient-centered clinical communication skills with the electronic health record may help clinicians adapt and remain patient-centered. We developed an interactive workshop eliciting challenges and opportunities of working with the electronic health record in clinical practice, introduction of specific patient-centered behaviors and mindful practice techniques, and video demonstrating contrasts in common behavior and "better practices." One hundred thirty-nine resident physicians and faculty supervisors in five residency training programs at the University of Rochester Medical Center participated in the workshops. Participants were asked to complete an 11-item survey of behaviors related to their use of the electronic health record prior to training and after attending training. We used paired t-tests to assess changes in self-reported behavior from pre-intervention to post-intervention. We trained 139 clinicians in the workshops; 110 participants completed the baseline assessment and 39 completed both the baseline and post-intervention assessment. Data from post-curriculum respondents found a statistically significant increase in "I told the patient when turning my attention from the patient to the computer," from 60% of the time prior to the training to 70% of the time after. Data from our program evaluation demonstrated improvement in one communication behavior. Sample size limited the detection of other changes; further research should investigate effective training techniques for patient-centered communication while using the electronic health record. © The Author(s) 2016.

    There is increasing interest in the use of information and communication technologies to improve how clinicians communicate in hospital settings. We implemented a communication system with support for physician handover and secure messaging on 2 general internal medicine wards. We measured usage and surveyed physicians and nurses on perceptions of the system's effects on communication. Between May 2011 and August 2012, a clinical teaching team received, on average, 14.8 messages per day through the system. Messages were typically sent as urgent (69.1%) and requested a text reply (76.5%). For messages requesting a text reply, 8.6% did not receive a reply. For those messages that did receive a reply, the median response time was 2.3 minutes, and 84.5% of messages received a reply within 15 minutes. Of those who completed the survey, 95.3% were medical residents (82 of 86) and 81.7% were nurses (83 of 116). Medical trainees (82.8%) and nursing staff (78.3%) agreed or strongly agreed that the system helped to speed up their daily work tasks. Overall, 67.1% of the trainees and 73.2% of nurses agreed or strongly agreed that the system made them more accountable in their clinical roles. Only 35.8% of physicians and 26.3% of nurses agreed or strongly agreed that the system was useful for communicating complex issues. In summary, with a system designed to improve communication, we found that there was high uptake and that users perceived that the system improved efficiency and accountability but was not appropriate for communicating complex issues. © 2014 Society of Hospital Medicine.

    The International Federation of Gynecology and Obstetrics (FIGO) supported the Nepal Society of Obstetricians and Gynaecologists (NESOG) to help influence national health policy and practice through FIGO's Leadership in Obstetrics and Gynecology for Impact and Change (LOGIC) Initiative in Maternal and Newborn Health. An Organizational Capacity Improvement Framework, developed by the Society of Obstetricians and Gynaecologists of Canada (SOGC), was used to evaluate NESOG's initial baseline organizational capacity in 2010. Communication among NESOG members was rated as moderate (39%). Several initiatives, such as the use of high-speed internet access, group SMS texts and emails for information sharing, member profile updates, use of social media, and regular updates to the NESOG website were examples of interventions that resulted in improved participation of members in NESOG's activities. Members were impressively active in reciprocating via Facebook, and via participation in online voting in the NESOG elections (84%). Copyright © 2014. Published by Elsevier Ireland Ltd.

  5. An Improved Fruit Fly Optimization Algorithm Inspired from Cell Communication Mechanism

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Fruit fly optimization algorithm (FOA invented recently is a new swarm intelligence method based on fruit fly’s foraging behaviors and has been shown to be competitive with existing evolutionary algorithms, such as particle swarm optimization (PSO algorithm. However, there are still some disadvantages in the FOA, such as low convergence precision, easily trapped in a local optimum value at the later evolution stage. This paper presents an improved FOA based on the cell communication mechanism (CFOA, by considering the information of the global worst, mean, and best solutions into the search strategy to improve the exploitation. The results from a set of numerical benchmark functions show that the CFOA outperforms the FOA and the PSO in most of the experiments. Further, the CFOA is applied to optimize the controller for preoxidation furnaces in carbon fibers production. Simulation results demonstrate the effectiveness of the CFOA.

    In recent years, climate impact assessments of relevance to the agricultural and forestry sectors have received considerable attention. Current ecosystem models commonly capture the effect of a warmer climate on biomass production, but they rarely sufficiently capture potential losses caused by pests, pathogens and extreme weather events. In addition, alternative management regimes may not be integrated in the models. A way to improve the quality of climate impact assessments is to increase the science-stakeholder collaboration, and in a two-way dialog link empirical experience and impact modelling with policy and strategies for sustainable management. In this paper we give a brief overview of different ecosystem modelling methods, discuss how to include ecological and management aspects, and highlight the importance of science-stakeholder communication. By this, we hope to stimulate a discussion among the science-stakeholder communities on how to quantify the potential for climate change adaptation by improving the realism in the models.

    We analyze the security of a quantum secure direct communication and authentication protocol based on single photons. We first give an impersonation attack on the protocol. The cryptanalysis shows that there is a gap in the authentication procedure of the protocol so that an opponent can reveal the secret information by an undetectable attempt. We then propose an improvement for the protocol and show it closes the gap by applying a mutual authentication procedure. In the improved protocol single photons are transmitted once in a session, so it is easy to implement as the primary protocol. Furthermore, we use a novel technique for secret order rearrangement of photons by which not only quantum storage is eliminated also a secret key can be reused securely. So the new protocol is applicable in practical approaches like embedded system devices.

    2017-05-01

    Inter-satellite optical wireless communication (IsOWC) systems can be chosen over existing microwave satellite systems for deploying in space in the future due to their high bandwidth, small size, light weight, low power and low cost. However, the IsOWC system suffers from various attenuations due to weather conditions, turbulence or scintillations which limit its performance and decreases its availability. So, in order to improve the performance, IsOWC system using directly modulated laser source is proposed in this work. The system is designed and evaluated to be suitable for high data rate transmissions up to 10 Gbps. The performance of the system is investigated in order to reduce the cost and complexity of link and improving the quality of information signal. Further the proposed IsOWC system is analysed using BER analyser, power meter and oscilloscope Visualizer.

  10. Communicating Eco-Friendly Benefits: Why Accidental Improvements May Be Better Received by Consumers

    Directory of Open Access Journals (Sweden)

    Newman George E.

    2016-05-01

    Full Text Available Doing good does not necessarily imply doing well for a company. Ironically, in the case of green products it can even be quite the contrary. Deliberately enhancing a product with environmental benefits to make it more appealing may actually lead to a decrease in consumer interest because consumers suspect that quality was reduced on other dimensions. Even explicitly stating that the company cares about both the environment and quality is not sufficient to overcome consumers’ skepticism, according to our experiments. Fortunately, there are ways to communicate environmental improvements successfully. Companies improving a basic product feature like making something more eco-friendly should either position the improvement as unintended or emphasize that the primary goal is improving the quality of the product. Focusing on eco-conscious market segments also helps to avoid harm and might even be beneficial. Improvements on dimensions that are not inherent to a product’s composition, like fair trade or other social benefits, turned out to be less critical in the experiments.

    2017-09-01

    This paper explains and demonstrates the pilot application of Triangulated Proxy Reporting (TPR); a practical technique for enhancing communication around people who have severe cognitive impairment (SCI). An introduction explains SCI and how this impacts on communication; and consequently on quality of care and quality of life. This is followed by an explanation of TPR and its origins in triangulation research techniques. An illustrative vignette explicates its utility and value in a group home for a resident with profound multiple disabilities. The Discussion and Conclusion sections propose the wider application of TPR for different cohorts of people with SCIs, their communication partners and service providers. TPR presents as a practical technique for enhancing communication interactions with people who have SCI. The paper demonstrates the potential of the technique for improving engagement amongst those with profound multiple disabilities, severe acquired brain injury and advanced dementia and their partners in and across different care settings. Implications for Rehabilitation Triangulated Proxy Reporting (TPR) shows potential to improve communications between people with severe cognitive impairments and their communication partners. TPR can lead to improved quality of care and quality of life for people with profound multiple disabilities, very advanced dementia and severe acquired brain injury, who otherwise are very difficult to support. TPR is a relatively simple and inexpensive technique that service providers can incorporate into practice to improving communications between clients with severe cognitive impairments, their carers and other support professionals.

    The technological advance has generated increasing demand for materials that can be used under high temperature, what includes intermetallic MR-Si-B (MR = refractory metal) alloys with multiphase structures, that can also be applied in oxide environments. Thus, this work had for objective the micro hardness study of the Hf-Si-B system alloys, heat treated at 1600 deg C, in the Hf rich region. Hf-Si-B alloys had been produced with blades of Hf (min. 99.8%), Si (min. 99.998%) and B (min. 99.5%), in the voltaic arc furnace and heat treated at 1600 deg C under argon atmosphere. The relationship of the phases had been previously identified by X-ray diffraction and contrast in backscattered electron imaging mode. The alloys had their hardness analyzed by method Vickers (micro hardness) with load of 0.05 kgf and 0.2 kgf and application time of 20 s. The results, obtained from the arithmetic mean of measurements for each alloy on the heterogeneous region, showed a mean hardness of 11.08 GPA, with small coefficient of variation of 3.8%. The borides HfB2 (19.34 GPa) e HfB - 11.76 GPa, showed the hardness higher than the silicides Hf2Si (8.57 GPa), Hf5Si3 (9.63 GPa), Hf3Si2 (11.66 GPa), Hf5Si4 (10.00 GPa), HfSi (10.02 GPa) e HfSi2 (8.61 GPa).

    We developed a novel individualised training program regarding end-of-life communication, designed to be time effective for busy junior-doctors working in hospital settings. We aimed to pilot this brief individualised training program with junior-doctors to explore its acceptability, feasibility and effect on the doctors' confidence, communication skills, attitudes towards psychosocial care and burnout. The content of the training intervention was informed by a systematic literature review and evidence-based clinical practice guidelines regarding end-of-life communication. The intervention was based on sound educational principles and involved three one-hour teaching sessions over a three-week period, including two individual sessions with an expert facilitator and simulated patient/caregiver. In addition, participants received written and audiovisual take-home learning materials. PARTICIPANTS were videotaped consulting with a simulated patient/caregiver pre/post training to assess the impact of the course on their communication behaviours. PARTICIPANTS completed de-identified questionnaires pre/post training, including self-assessed confidence, attitudes to psychosocial care, and the Maslach Burnout inventory. PARTICIPANTS included 22 junior-doctors from a large teaching hospital in Sydney, Australia. All participants reported that the training was useful, had been helpful for their communication with patients and that they would recommend the training to others. Significant improvements were found in participants' communication skills (in seven out of 21 specific and all three global communication behaviours assessed, range P=0.02 to confidence in communicating about relevant topics (P<0.001), attitudes towards psychosocial care (P=0.03) and sense of personal accomplishment (P=0.043). There were no overall differences in participants' burnout levels. This intervention shows promise and warrants further formal evaluation.

    2013-01-01

    Background and purpose: Optimizing communication between radiotherapy team members and patients and between colleagues requires training. This study applies a randomized controlled design to assess the efficacy of a 38-h communication skills training program. Material and methods: Four radiotherapy teams were randomly assigned either to a training program or to a waiting list. Team members’ communication skills and their self-efficacy to communicate in the context of an encounter with a simulated patient were the primary endpoints. These encounters were scheduled at the baseline and after training for the training group, and at the baseline and four months later for the waiting list group. Encounters were audiotaped and transcribed. Transcripts were analyzed with content analysis software (LaComm) and by an independent rater. Results: Eighty team members were included in the study. Compared to untrained team members, trained team members used more turns of speech with content oriented toward available resources in the team (relative rate [RR] = 1.38; p = 0.023), more assessment utterances (RR = 1.69; p < 0.001), more empathy (RR = 4.05; p = 0.037), more negotiation (RR = 2.34; p = 0.021) and more emotional words (RR = 1.32; p = 0.030), and their self-efficacy to communicate increased (p = 0.024 and p = 0.008, respectively). Conclusions: The training program was effective in improving team members’ communication skills and their self-efficacy to communicate in the context of an encounter with a simulated patient. Future study should assess the effect of this training program on communication with actual patients and their satisfaction. Moreover a cost-benefit analysis is needed, before implementing such an intensive training program on a broader scale

    A preliminary assessment of accuracy of a two-sites shore-based HF Radar network along the Venice Lagoon littoral was attempted by means of comparison with a 57.5 day-long ADCP current time series for the period September-October 2002. Results showed that radar measurements were accurate ( O . The main differences between the HF radar and surface ADCP currents can be explained in terms of random errors affecting the measurement technique and the daily sea breeze forcing, since low-pass filtering of current time series significantly improved the correlation and decreased the RMS of the differences between the two measured data set. Comparison of the semidiurnal (M2, S2) tidal band suggested good agreement between tidal ellipse amplitudes. Wind forcing on a daily time-scale (sea-breeze) was associated with larger differences between radar and ADCP currents at a diurnal band due to the presence of a vertical shear in the surface layer

    When planning a picture archiving and communications system (PACS) implementation and determining which equipment will be implemented in earlier and later phases, collection and analysis of selected data will aid in setting implementation priorities. If baseline data are acquired relative to performance objectives, the same information used for implementation planning can be used to measure performance improvement and outcomes. The main categories of data to choose from are: (1) financial data; (2) productivity data; (3) operational parameters; (4) clinical data; and (5) information about customer satisfaction. In the authors' experience, detailed workflow data have not proved valuable in measuring PACS performance and outcomes. Reviewing only one category of data in planning will not provide adequate basis for targeting operational improvements that will lead to the most significant gains. Quality improvement takes into account all factors in production: human capacity, materials, operating capital and assets. Once we have identified key areas of focus for quality improvement in each phase, we can translate objectives into implementation requirements and finally into detailed functional and performance requirements. Here, Integration Resources reports its experience measuring PACS performance relative to phased implementation strategies for three large medical centers. Each medical center had its own objectives for overcoming image management, physical/geographical, and functional/technical barriers. The report outlines (1) principal financial and nonfinancial measures used as performance indicators; (2) implementation strategies chosen by each of the three medical centers; and (3) the results of those strategies as compared with baseline data.

    Effective doctor-patient communication is essential for establishing a successful doctor-patient relationship and implementing high-quality health care. In this study, a novel urinary system-simulating physical model was designed and fabricated, and its content validity for improving doctor-patient communication was examined by conducting a randomized controlled trial in which this system was compared with photographs. A total of 240 inpatients were randomly selected and assigned to six doctors for treatment. After primary diagnosis and treatment had been determined, these patients were randomly divided into the experimental group and the control group. Patients in the experimental group participated in model-based doctor-patient communication, whereas control group patients received picture-based communication. Within 30 min after this communication, a Demographic Information Survey Scale and a Medical Interview Satisfaction Scale (MISS) were distributed to investigate patients' demographic characteristics and their assessments of total satisfaction, distress relief, communication comfort, rapport, and compliance intent. The study results demonstrated that the individual groups were comparable with respect to demographic variables but that relative to patients in the picture-based communication group, patients in the model-based communication group had significantly higher total satisfaction scores and higher ratings for distress relief, communication comfort, rapport, and compliance intent. These results indicate that the physical model is more effective than the pictures at improving doctor-patient communication and patient outcomes. The application of the physical model in doctor-patient communication is helpful and valuable and therefore merits widespread clinical popularization.

    Since the launch of the Global Polio Eradication Initiative (GPEI) in 1988, there has been a tremendous progress in the reduction of cases of poliomyelitis. The world is on the verge of achieving global polio eradication and in May 2013, the 66th World Health Assembly endorsed the Polio Eradication and Endgame Strategic Plan (PEESP) 2013-2018. The plan provides a timeline for the completion of the GPEI by eliminating all paralytic polio due to both wild and vaccine-related polioviruses. We reviewed how GPEI supported communicable disease surveillance in seven of the eight countries that were documented as part of World Health Organization African Region best practices documentation. Data from WHO African region was also reviewed to analyze the performance of measles cases based surveillance. All 7 countries (100%) which responded had integrated communicable diseases surveillance core functions with AFP surveillance. The difference is on the number of diseases included based on epidemiology of diseases in a particular country. The results showed that the polio eradication infrastructure has supported and improved the implementation of surveillance of other priority communicable diseases under integrated diseases surveillance and response strategy. As we approach polio eradication, polio-eradication initiative staff, financial resources, and infrastructure can be used as one strategy to build IDSR in Africa. As we are now focusing on measles and rubella elimination by the year 2020, other disease-specific programs having similar goals of eradicating and eliminating diseases like malaria, might consider investing in general infectious disease surveillance following the polio example.

    2012-01-01

    This paper presents a conceptual framework that can support efforts to integrate human factors (HF) into the work system design process, where improved and cost-effective application of HF is possible. The framework advocates strategies of broad stakeholder participation, linking of performance and health goals, and process focussed change tools that can help practitioners engage in improvements to embed HF into a firm's work system design process. Recommended tools include business process mapping of the design process, implementing design criteria, using cognitive mapping to connect to managers' strategic goals, tactical use of training and adopting virtual HF (VHF) tools to support the integration effort. Consistent with organisational change research, the framework provides guidance but does not suggest a strict set of steps. This allows more adaptability for the practitioner who must navigate within a particular organisational context to secure support for embedding HF into the design process for improved operator wellbeing and system performance. There has been little scientific literature about how a practitioner might integrate HF into a company's work system design process. This paper proposes a framework for this effort by presenting a coherent conceptual framework, process tools, design tools and procedural advice that can be adapted for a target organisation.

    Although effective communication with families of critically ill patients is a vital component of quality care, training in this field is neglected. The article aims to validate communication skills training program for anesthesiology residents in the intensive care set up. Ten anesthesia residents, following 3 months of Intensive Care Unit (ICU) rotation, had 4 hours of lectures and one day simulation-based communication skills training with families of critically ill patients. Participants completed an attitude questionnaire over 3 time periods--before training [t1], immediately following training (t2) and three months following training (t3). The participants' communication skills were assessed by two blinded independent observers using the SEGUE framework while performing a simulation-based scenario at t1 and t3. Seven participants finished the study protocol. Participants ndicated communication importance as 3.68 +/- 0.58 (t1), 4.05 +/- 0.59 (t2), 4.13 +/- 0.64 (t3); their communication ability as 3.09 +/- 0.90 (t1), 3.70 +/- 0.80 (t2), 3.57 +/- 0.64 (t3); the contribution of lecture to communication 3.04 +/- 0.43 (t1), 3.83 +/- 0.39 (t2), 3.87 +/- 0.51 (t3), and contribution of simulation training to communication 3.00 +/- 0.71 (t1), 4.04 +/- 0.52 (t2), 3.84 +/- 0.31 (t3). The differences did not reach statistical significance. Objective assessment of the communication skills using the SEGUE framework indicated that 6/7 participants improved their communication skills, with communication ability before training at 2.66 +/- 0.83 and 1 month following training it was 3.38 +/- 0.78 (p = 0.09). This preliminary study demonstrates the value of communication skills training in the intensive care environment.

    To provide adequate nursing care it is important for nursing staff to communicate effectively with people with dementia. Due to their limited communication skills, people with dementia have difficulties in understanding communication and expressing themselves verbally. Nursing staff members often report communication difficulties with people with dementia, which emphasises the urgent need for interventions to improve their communication with people in this specific target group. To provide an up-to-date overview of communication interventions that are applicable during daily nursing care activities, irrespective of care setting, and to describe the effects on communication outcomes in people with dementia and nursing staff. Systematic literature review DATA SOURCES: The Cochrane Library, CINAHL, PsycINFO, and Pubmed databases were searched for all articles published until the 23rd of February 2016. Papers were included, if: (1) interventions focused on communication between nursing staff and people with dementia and were applicable during daily nursing care; (2) studies were (randomised) controlled trials; (3) papers were written in English, Dutch, or German. Data were extracted on content and communication outcomes of interventions, and on methodological quality of the studies. The data extraction form and methodological quality checklist were based on the Method Guidelines for Systematic Reviews for the Cochrane Back Review Group. Six studies on communication interventions were included. All of the studies incorporated a communication skills training for nursing staff with a broad range in frequency, duration and content. In addition, there was wide variation in the communication outcome measures used. Four studies measured non-verbal communication, all found positive effects on at least some of the communication outcomes. Four studies measured verbal communication, of which three found positive effects on at least one of the measured outcomes. Methodological

  9. Mechanisms and selectivity for etching of HfO2 and Si in BCl3 plasmas

    The authors have investigated plasma etching of HfO 2 , a high dielectric constant material, and poly-Si in BCl 3 plasmas. Etching rates were measured as a function of substrate temperature (T s ) at several source powers. Activation energies range from 0.2 to 1.0 kcal/mol for HfO 2 and from 0.8 to 1.8 kcal/mol for Si, with little or no dependence on source power (20-200 W). These low activation energies suggest that product removal is limited by chemical sputtering of the chemisorbed Hf or Si-containing layer, with a higher T s only modestly increasing the chemical sputtering rate. The slightly lower activation energy for HfO 2 results in a small improvement in selectivity over Si at low temperature. The surface layers formed on HfO 2 and Si after etching in BCl 3 plasmas were also investigated by vacuum-transfer x-ray photoelectron spectroscopy. A thin boron-containing layer was observed on partially etched HfO 2 and on poly-Si after etching through HfO 2 films. For HfO 2 , a single B(1s) feature at 194 eV was ascribed to a heavily oxidized species with bonding similar to B 2 O 3 . B(1s) features were observed for poly-Si surfaces at 187.6 eV (B bound to Si), 189.8 eV, and 193 eV (both ascribed to BO x Cl y ). In the presence of a deliberately added 0.5% air, the B-containing layer on HfO 2 is largely unaffected, while that on Si converts to a thick layer with a single B(1s) peak at 194 eV and an approximate stoichiometry of B 3 O 4 Cl

  10. Storytelling in the context of vaccine refusal: a strategy to improve communication and immunisation.

    The December 2014 outbreak of measles in California impacted over 100 children and served as a reminder that this disease still plagues the USA, even 50 years following the first licensed vaccine. Refusal of vaccination is a complicated and multifaceted issue, one that clearly demands a closer look by paediatricians and public health officials alike. While medical doctors and scientists are trained to practice 'evidence-based medicine', and studies of vaccine safety and efficacy speak the language of statistics, there is reason to believe that this is not the most effective strategy for communicating with all groups of parents. Herein, we consider other methods such as narrative practices that employ stories and appeal more directly to parents. We also examine how doctors are trained to disseminate information and whether there are reasonable supplementary methods that could be used to improve vaccine communication and ultimately immunisation rates.

    2017-11-01

    Crew Resource Management (CRM), a method focused on the management of human error and risk reduction, has shown promise in reducing communication failure in health care. The purpose of this project was to develop a virtual training program in CRM principles of effective leadership and followership, and evaluate the applicability to nurses working in the hospital setting. The intervention included the development of a virtual CRM training program consisting of a self-learning module and virtual simulation. Beta testing of the module was conducted by six nurses, followed by an evaluation of the training program by nurses (n = 5) in a general medicine department. Nurses reported the overall program to be worthwhile (X̄= 5; SD = 0.5), with great applicability to nursing care (X̄= 4.5, SD = 0.5). Nurses completing the simulation activity reported strong agreement to CRM applicability and training effectiveness. The CRM training module proved to be applicable to nursing care and is ready for widespread use to improve patient care and communication. J Contin Educ Nurs. 2017;48(11):525-532.

  12. SEE: improving nurse-patient communications and preventing software piracy in nurse call applications.

    2012-06-01

    Nurse call system is an electrically functioning system by which patients can call upon from a bedside station or from a duty station. An intermittent tone shall be heard and a corridor lamp located outside the room starts blinking with a slow or a faster rate depending on the call origination. It is essential to alert nurses on time so that they can offer care and comfort without any delay. There are currently many devices available for a nurse call system to improve communication between nurses and patients such as pagers, RFID (radio frequency identification) badges, wireless phones and so on. To integrate all these devices into an existing nurse call system and make they communicate with each other, we propose software client applications called bridges in this paper. We also propose a window server application called SEE (Supervised Event Executive) that delivers messages among these devices. A single hardware dongle is utilized for authentication and copy protection for SEE. Protecting SEE with securities provided by dongle only is a weak defense against hackers. In this paper, we develop some defense patterns for hackers such as calculating checksums in runtime, making calls to dongle from multiple places in code and handling errors properly by logging them into database.

  13. Engineering Ethics Education on the Basis of Continuous Education to Improve Communication Ability

    Science.gov (United States)

    Takahara, Kenji; Kajiwara, Toshinori

    The paper proposes the engineering ethics education method for students on the basis of continuous education to improve communication ability. First, through a debate, the students acquire the fundamental skills required to marshal their arguments, to construct the rebuttals and to summarize the debates. Secondly, the students study the fundamental techniques to make a presentation on technical subjects related to electrical engineering. Following these classes, in the lecture of engineering ethics, the students probe the cause of each accident and consider the better means for avoiding such an accident, each other. In most cases, the students can express right and commonsensical opinions from an ethical standpoint. However, they can hardly make judgments when the situations such as the human relations in the above accidents are set concretely. During the engineering ethics class, the students come to know that human relations behind the case make the ethical matters more complicated. Furthermore, they come to understand that facilitating daily communications with co-workers and/or bosses is very important in order to avoid the accidents. The recognition of the students is just the results of the continuous education through three years. It can be said that the engineering ethics education thus constructed makes the students raise such spontaneous awareness and their ethical qualities as engineers.

    The purpose of this pilot study was to explore the impact of a certified nurse's aide (CNA)-led interdisciplinary teamwork and communication intervention on perceived quality of work environment and six-month job intentions. CNAs are frequently excluded from team communication and decision-making, which often leads to job dissatisfaction with high levels of staff turnover. Using a mixed quantitative and qualitative approach with pre- post-program design, the intervention utilized the strategy of debriefing from the national patient safety initiative, TeamSTEPPS. Inherent in the program design, entitled Long Term Care (LTC) Team Talk, was the involvement of the CNAs in the development of the intervention as an empowering process on two wings of a transitional care unit in a long-term care facility in upstate NY. CNAs' perceptions of work environment quality were measured using a Quality of Work Life (QWL) instrument. Additionally, job turnover intent within six months was assessed. Results indicated improved scores on nearly all QWL subscales anticipated to be impacted, and enhanced perceived empowerment of the CNAs on each wing albeit through somewhat different experiential processes. The program is highly portable and can potentially be implemented in a variety of long-term care settings. Copyright © 2014 Mosby, Inc. All rights reserved.

    A participatory ergonomics programme was implemented in an automotive parts manufacturing factory in which an ergonomics change team was formed, composed of members from management, the organized labour union and the research team. It was hypothesized that the participatory nature of this change process would result in enhanced worker perceptions of workplace communication dynamics, decision latitude and influence, which in conjunction with anticipated mechanical exposure reductions would lead to reduced worker pain severity. Utilizing a sister plant in the corporation as a referent group, a quasi-experimental design was employed with a longitudinal, repeat questionnaire approach to document pre-post intervention changes. Nine participatory activities (psychosocial interventions) were implemented as part of the process. Communication dynamics regarding ergonomics were significantly enhanced at the intervention plant compared to the referent plant. However, there were no significantly different changes in worker perceptions of decision latitude or influence between the two plants, nor did pain severity change. Possible explanations for these results include limited intervention intensity, context and co-intervention differences between the two plants, high plant turnover reducing the statistical power of the study and lack of sensitivity and specificity in the psychosocial measures used. Further research should include the development of psychosocial tools more specific to participatory ergonomic interventions and the assessment of the extent of change in psychosocial factors that might be associated with improvements in pain.

    Full Text Available Understanding the short- and long-term impacts of a biomonitoring and exposure project and reporting personal results back to study participants is critical for guiding future efforts, especially in the context of environmental justice. The purpose of this study was to evaluate learning outcomes from environmental communication efforts and whether environmental health literacy goals were met in an environmental justice community. We conducted 14 interviews with parents who had participated in the University of Arizona’s Metals Exposure Study in Homes and analyzed their responses using NVivo, a qualitative data management and analysis program. Key findings were that participants used the data to cope with their challenging circumstances, the majority of participants described changing their families’ household behaviors, and participants reported specific interventions to reduce family exposures. The strength of this study is that it provides insight into what people learn and gain from such results communication efforts, what participants want to know, and what type of additional information participants need to advance their environmental health literacy. This information can help improve future report back efforts and advance environmental health and justice.

    The discharge letter is a key component of the communication pathway between the hospital and primary care. Accuracy and timeliness of delivery are crucial to ensure continuity of patient care. Electronic discharge summaries (EDS) and prescriptions have been shown to improve quality of discharge information for general practitioners (GPs). The aim of this study was to evaluate the effect of a new EDS on GP satisfaction levels and accuracy of discharge diagnosis. A GP survey was carried out whereby semi-structured interviews were conducted with 13 GPs from three primary care centres who receive a high volume of discharge letters from the hospital. A chart review was carried out on 90 charts to compare accuracy of ICD-10 coding of Non-Consultant Hospital Doctors (NCHDs) with that of trained Hopital In-Patient Enquiry (HIPE) coders. GP satisfaction levels were over 90 % with most aspects of the EDS, including amount of information (97 %), accuracy (95 %), GP information and follow-up (97 %) and medications (91 %). 70 % of GPs received the EDS within 2 weeks. ICD-10 coding of discharge diagnosis by NCHDs had an accuracy of 33 %, compared with 95.6 % when done by trained coders (p communication with primary care. It has led to a very high satisfaction rating with GPs. ICD-10 coding was found to be grossly inaccurate when carried out by NCHDs and it is more appropriate for this task to be carried out by trained coders.

    The use of Computer Aided Dispatch (CAD) for information exchange between the corporate information network and the field personnel of the CU Gas Group was described. CAD was described as two interconnected systems; a large mainframe software system which interfaces with the radio transmission system as well as the Customer Information System (CIS), and a mini computer system which consists of mobile data terminals (MDTs), the radio hardware and the software necessary to communicate with the MDTs. Further details were given on the functionality of both the mainframe, as well as the mini computer system. Some of the functions performed by the CAD include call taking, employee calendar, work assignment, filling work, dispatching, reporting, correcting errors, providing order status information, fleet monitoring, appointments, and many others. The implementation process, the challenges faced by the communications team and their interactions with the organization was also described. The most important benefit was claimed to be improved customer service. The significance of that to corporate strategy was stressed

    Talking about sexual health can be a challenge for some older women. This project was initiated to identify key factors that improve communication between aging women and their primary care providers. A sample of women (aged 60+) completed an online survey regarding their intent to communicate with a provider about sexual health. Using the integrative model of behavioral prediction as a guide, the survey instrument captured data on attitudes, perceived norms, self-efficacy, and intent to communicate with a provider about sexual health. Data were analyzed using structural equation modeling. Self-efficacy and perceived norms were the most important factors predicting intent to communicate for this sample of women. Intent did not vary with race, but mean scores of the predictors of intent varied for African American and White women. Results can guide practice and intervention with ethnically diverse older women who may be struggling to communicate about their sexual health concerns. © The Author(s) 2013.

    Deploying an intentional daily management process is a key part to create high-reliability culture. Key components described in the literature for a successfully daily management process include leadership standard work, visual controls, daily accountability processes, and the discipline to stick to the process over the long term. We believe that the institution of a daily readiness huddle has helped us better coordinate and communicate as a department and improved our ability to deliver imaging services on a daily basis. The daily readiness huddle has enabled us to more rapidly identify issues and has brought accountability to seeing solutions to those issues brought to fruition. In addition, it has helped with team building, including between the radiologists and the nonphysician staff. Copyright © 2017 Elsevier Inc. All rights reserved.

    A new, improved importance sampling (IIS) approach to simulation is considered. Some basic concepts of IS are introduced, and detailed evolutions of simulation estimation variances for Monte Carlo (MC) and IS simulations are given. The general results obtained from these evolutions are applied to the specific previously known conventional importance sampling (CIS) technique and the new IIS technique. The derivation for a linear system with no signal random memory is considered in some detail. For the CIS technique, the optimum input scaling parameter is found, while for the IIS technique, the optimum translation parameter is found. The results are generalized to a linear system with memory and signals. Specific numerical and simulation results are given which show the advantages of CIS over MC and IIS over CIS for simulations of digital communications systems.

    Recently Bu and Wang [Bu S, Wang B-H. Chaos, Solitons and Fractals 2004;19(4):919-24] proposed a simple modulation method aiming to improve the security of chaos-based secure communications against return-map-based attacks. Soon this modulation method was independently cryptanalyzed by Chee et al. [Chee CY, Xu D, Bishop SR. Chaos, Solitons and Fractals 2004;21(5):1129-34], Wu et al. [Wu X, Hu H, Zhang B.

As an enhancement to the Bu-Wang method, an improving scheme was suggested by Wu et al. by removing the relationship between the modulating function and the zero-points. The present paper points out that the improved scheme proposed by Wu et al. is still insecure against a new attack. Compared with the existing attacks, the proposed attack is more powerful and can also break the original Bu-Wang scheme. Furthermore, it is pointed out that the security of the modulation-based schemes proposed by Wu et al. is not so satisfactory from a pure cryptographical point of view. The synchronization performance of this class of modulation-based schemes is also discussed

    Ensuring that written materials used in behavioral interventions are clear is important to support behavior change. This study used the Clear Communication Index (CCI) to assess the original and revised versions of three types of written participant materials from the SIPsmartER intervention. Materials were revised based on original scoring. Scores for the entire index were significantly higher among revised versions than originals (57% versus 41%, p < 0.001); however, few revised materials (n = 2 of 53) achieved the benchmark of ≥90%. Handouts scored higher than worksheets and slide sets for both versions. The proportion of materials scored as having "a single main message" significantly increased between versions for worksheets (7% to 57%, p = 0.003) and slide sets (33% to 67%, p = 0.004). Across individual items, most significant improvements were in Core, with four-items related to the material having a single main message. Findings demonstrate that SIPsmartER's revised materials improved after CCI-informed edits. They advance the evidence and application of the CCI, suggesting it can be effectively used to support improvement in clarity of different types of written materials used in behavioral interventions. Implications for practical considerations of using the tool and suggestions for modifications for specific types of materials are presented.

    Documentation of urgent referrals to neurosurgical units and communication with referring hospitals is critical for effective handover and appropriate continuity of care within a tertiary service. Referrals to our neurosurgical unit were audited and we found that the majority of referrals were not documented and this led to more calls to the on-call neurosurgery registrar regarding old referrals. We implemented a new referral system in an attempt to improve documentation of referrals, communication with our referring hospitals and to professionalise the service we offer them. During a 14-day period, number of bleeps, missed bleeps, calls discussing new referrals and previously processed referrals were recorded. Whether new referrals were appropriately documented and referrers received a written response was also recorded. A commercially provided secure cloud-based data archiving telecommunications and database platform for referrals was subsequently introduced within the Trust and the questionnaire repeated during another 14-day period 1 year after implementation. Missed bleeps per day reduced from 16% (SD ± 6.4%) to 9% (SD ± 4.8%; df = 13, paired t-tests p = 0.007) and mean calls per day clarifying previous referrals reduced from 10 (SD ± 4) to 5 (SD ± 3.5; df = 13, p = 0.003). Documentation of new referrals increased from 43% (74/174) to 85% (181/210), and responses to referrals increased from 74% to 98%. The use of a secure cloud-based data archiving telecommunications and database platform significantly increased the documentation of new referrals. This led to fewer missed bleeps and fewer calls about old referrals for the on call registrar. This system of documenting referrals results in improved continuity of care for neurosurgical patients, a significant reduction in risk for Trusts and a more efficient use of Registrar time.

    Empirically based couple therapy results in significant improvements in relationship satisfaction for the average couple; however, further research is needed to identify mediators that lead to change and to ensure that improvements in mediators predict subsequent-not just concurrent-relationship satisfaction. In addition, given that much of the current literature on couple therapy examines outcomes in a research environment, it is important to examine mediators in a treatment-as-usual setting. To address these questions, 161 heterosexual couples (322 individuals) received treatment-as-usual couple therapy at one of two Veteran Administration Medical Centers (M = 5.0 and 13.0 sessions at the two sites) and were assessed before every session. The majority of couples were married (85%) and had been together for a median of 7.8 years (SD = 13). Participants were primarily White, non-Hispanic (69%), African American (21%), and White, Hispanic/Latino (8%). Individuals' own self-reported improvements in communication, emotional closeness, and psychological distress (but not frequency of behaviors targeted in treatment) mediated the effect of treatment on their subsequent relationship satisfaction. When all significant mediators were examined simultaneously, improvements in men's and women's emotional closeness and men's psychological distress independently mediated subsequent relationship satisfaction. In contrast, improvements in earlier relationship satisfaction mediated the effect of treatment only on subsequent psychological distress. This study identifies unique mediators of treatment effects and shows that gains in mechanisms predict subsequent relationship satisfaction. Future investigations should focus on the role of emotional closeness and psychological distress-constructs that have often been neglected-in couple therapy.

    Full Text Available Abstract Background This paper describes the community engagement process undertaken to ascertain the focus, development and implementation of an intervention to improve iodised salt consumption in rural communities in North West Pakistan. The Jirga is a traditional informal structure, which gathers men respected within their community and acts in a governing and decision-making capacity in the Pukhtoon culture. The Jirga system had a dual purpose for the study: to access men from the community to discuss the importance of iodised salt, and as an engagement process for the intervention. Methods A number of qualitative data collection activities were undertaken, with Jirga members and their wives, male and female outreach workers and two groups of women, under and over 40 years old. The aim of these was to highlight the communication channels and levers of influence on health behaviour, which were multiple and complex and all needed to be taken into consideration in order to ensure successful and locally sensitive community engagement. Results Communication channels are described within local families and the communities around them. The key influential role of the Jirga is highlighted as linked both to the standing of its members and the community cohesion ethos that it embodies. Engaging Jirga members in discussions about iodised salt was key in designing an intervention that would activate the most influential levers to decision making in the community. Gendered decision-making processes within the household have been highlighted as restricting women’s autonomy. Whilst in one respect our data confirm this, a more complex hierarchy of decisional power has been highlighted, whereby the concept of ‘wisdom’- an amalgamation of age, experience and education- presents important possibilities. Community members with the least autonomy are the youngest uneducated females, who rely on a web of socially and culturally determined ways to influence

    The effect of room temperature ozone oxidation treatment on thin HfSiO film grown by atomic layer deposition (ALD) has been investigated. The optical and electrical properties with different post-ozone oxidation time were characterized. The evolution of ozone interacting with HfSiO films was clearly illuminated. Ozone can repair the lossy chemical bonds and vacancies, resulting in the improvement of packing density and polarizability of HfSiO films. With more ozone entering the HfSiO films, the refractive index, dielectric constant, and interfacial properties can be greatly upgraded. Furthermore, the frequency dispersion of ALD-HfSiO film can be improved after O 3 treatment time for 8 min. (orig.)

    Few research studies have examined longitudinal improvements in oral communication skills and quality of peer relationships of children with implants. Moreover, although the emerging literature suggests that improvement in social functioning follows improvement in oral communication, it is still unknown what factors enhance or impede the relations between these constructs. Based on parent interviews, the current study examined the long-term improvements in speech and oral language skills and relationships with hearing peers in 19 implanted children. Results demonstrate that on average, children continue to improve in oral communication skills and quality of peer relationships even years after implantation, especially those with initial poorer skills. While oral communication ability and quality of peer relationships are strongly associated at each time point, gains in these two variables are associated only for some of the children. Other factors, including self-confidence and peer acceptance, seem to moderate this relationship. Qualitative data are presented to illustrate these relations among variables and to assist in theory building. The results highlight the need for more specific examination of various developmental periods in combination with the progress of oral communication and peer relationships among children with implants. © 2013 John Wiley & Sons Ltd.

    Full Text Available Woojung Lee, Youran Noh, Hyeonjin Kang, Song Hee Hong Research Institute of Pharmaceutical Sciences, College of Pharmacy, Seoul National University, Seoul, Korea Background: Understanding how patient–physician communication affects patients’ medication experience would help hypertensive patients maintain their regular long-term medication therapy. This study aimed to examine whether patient–physician communication (information and interpersonal treatment affects patients’ medication experience directly or indirectly through changing medication adherence for each of the two communication domains.Methods: A self-administered cross-sectional survey was conducted for older patients who had visited a community senior center as a member. Two communication domains were assessed using two subscales of the Primary Care Assessment Survey. Medication adherence and experience were measured using the Morisky Medication Adherence Scale and a five-point Likert scale, respectively. Mediatory effects were assessed via Baron and Kenny’s procedure and a Sobel test. Results: Patient–physician communication had a positive prediction on patients’ medication experience (β=0.25, P=0.03, and this was fully mediated by medication adherence (z=3.62, P<0.001. Of the two components of patient–physician communication, only informative communication showed a mediatory effect (z=2.21, P=0.03. Conclusion: Patient–physician communication, specifically informative communication, had the potential to improve patients’ medication experience via changes in medication adherence. This finding can inform health care stakeholders of the mediatory role of medication adherence in ensuring favorable medication experience for older hypertensive patients by fostering informative patient–physician communication.

    1982-01-01

    There were four basic questions addressed in this report that relate to the HF interaction in the environment. As to whether HF hydrates in the vapor phase and what the rate of that hydration is, there seems ample evidence that HF hydrates readily in the vapor phase and the rate of that hydration is very fast, i.e., dHF/dt greater than or equal to 25 torr sec -1 . Concerning under what conditions condensation of the hydrate will occur and whether a third body is required for condensation, it was found that HF does effect the dew point or condensation of water and data was presented indicating the extent of that effect. It was also determined that condensation will occur without a third body present. Thus, in attempting to model an HF release for the Safety Analysis Report the hydration of HF and the subsequent heat released may be treated as occurring instantaneously; but the ultimate disposition of the HF will be strongly dependent upon the environmental conditions at the time of the release

    This review introduces the concept of culture-sensitive health communication. The basic premise is that congruency between the recipient's cultural characteristics and the respective message will increase the communication's effectiveness. Culture-sensitive health communication is therefore defined as the deliberate and evidence-informed adaptation of health communication to the recipients' cultural background in order to increase knowledge and improve preparation for medical decision making and to enhance the persuasiveness of messages in health promotion. To achieve effective health communication in varying cultural contexts, an empirically and theoretically based understanding of culture will be indispensable. We therefore define culture, discuss which evolutionary and structural factors contribute to the development of cultural diversity, and examine how differences are conceptualized as scientific constructs in current models of cultural differences. In addition, we will explicate the implications of cultural differences for psychological theorizing, because common constructs of health behavior theories and decision making, such as attitudes or risk perception, are subject to cultural variation. In terms of communication, we will review both communication strategies and channels that are used to disseminate health messages, and we will discuss the implications of cultural differences for their effectiveness. Finally, we propose an agenda both for science and for practice to advance and apply the evidence base for culture-sensitive health communication. This calls for more interdisciplinary research between science and practice but also between scientific disciplines and between basic and applied research. © The Author(s) 2015.

    Nowak, Glen J; Shen, Angela K; Schwartz, Jason L

    2017-10-09

    Vaccines have much relevance and promise for improving adult health in the United States, but to date, overall use and uptake remain far below desired levels. Many adults have not received recommended vaccinations and many healthcare providers do not strongly and actively encourage their use with patients. This has led some public health and medical experts to conclude that adult vaccines are severely undervalued by the U.S. public and healthcare providers and to call for campaigns and communication-based efforts to foster increased appreciation, and in turn, higher adult immunization rates. A narrative integrative review that draws upon the vaccine valuation and health communication literatures is used to develop a framework to guide campaign and communication-based efforts to improve public, provider, and policymakers' assessment of the value of adult vaccination. The review does this by: (1) distinguishing social psychological value from economic value; (2) identifying the implications of social psychological value considerations for adult vaccination-related communication campaigns; and (3) using five core health communication considerations to illustrate how social psychological notions of value can be integrated into campaigns or communication that are intended to improve adult vaccination value perceptions and assessments, and in turn, motivate greater support for and uptake of recommended adult vaccines.

    High sensitivity experiments with {sup 48}Ca, {sup 18}O and {sup 9}Be induced reactions using the ESSA-30, TESSA-3 and NORDBALL arrays have provided extensive new information on the high spin level structures of {sup 174}Hf and {sup 175}Hf. During the series of experiments, several new bands have been found and most known bands have been extended considerably. Spin and excitation energy ranges for {sup 174}Hf are now {approx} 35 {Dirac_h} and {approx} 13 MeV, respectively, and for {sup 175}Hf ranges are {approx} 30 {Dirac_h} and {approx} 7 MeV. respectively. Several new high-K structures have been found in {sup 174}Hf and the structure of these and the already known high-K bands in both nuclei together with the new Tilted Axis Cranking approach might explain the small K-hindrances observed for K-isomers in this region.

    Full Text Available Abstract High frequency (HF band has both military and civilian uses. It can be used either as a primary or backup communication link. Automatic modulation classification (AMC is of an utmost importance in this band for the purpose of communications monitoring; e.g., signal intelligence and spectrum management. A widely used method for AMC is based on pattern recognition (PR. Such a method has two main steps: feature extraction and classification. The first step is generally performed in the presence of channel noise. Recent studies show that HF noise could be modeled by Gaussian or bi-kappa distributions, depending on day-time. Therefore, it is anticipated that change in noise model will have impact on features extraction stage. In this article, we investigate the robustness of well known digitally modulated signal features against variation in HF noise. Specifically, we consider temporal time domain (TTD features, higher order cumulants (HOC, and wavelet based features. In addition, we propose new features extracted from the constellation diagram and evaluate their robustness against the change in noise model. This study is targeting 2PSK, 4PSK, 8PSK, 16QAM, 32QAM, and 64QAM modulations, as they are commonly used in HF communications.

    In this paper, we propose a performance improvement and cost-efficient discrete Hartley transform (DHT)-based asymmetrically clipped optical orthogonal frequency division multiplexing (ACO-OFDM) scheme for visible light communications (VLC). The simple one-dimensional modulation constellation and simplified encoding structure reduce the complexity of system considerably. The DHT-spreading technique is employed to reduce peak-to-average power ratio (PAPR) of ACO-OFDM signals. Moreover, the intra-symbol frequency-domain averaging (ISFA) technique is used to increase the accuracy of channel estimation by removing the effect of ambient noise in the VLC channel effectively. To verify the feasibility of the proposed scheme, we study its performance via simulation. This scheme reduces the requirement to the resolution of DAC and increases the tolerance to the nonlinear characteristics of LED, both of which are cost-efficient. At forward error correction (FEC) limit (BER = 1 × 10-3), simulation results illustrate that compared with DHT-based ACO-OFDM without the ISFA technique, our scheme has 3.2 dB and 2.7 dB improvement of the required Eb /N0 when BPSK and 4-PAM are modulated, respectively.

    Full Text Available This study aims to improve students’ speaking skills using the combined strategies of communication game, recorded role play and peer feedback activities. This action research took place at an English institution in Jakarta, Indonesia and collected the data by observing the learning process with the collaborator, analyzing the video during the class, making field notes, conducting tests (pretest and post test and interviewing students. There were three cycles in this study. Results of the tests showed that students’ speaking skills improved. The mean score of pre-test was 3.1, while the mean score of post-test in cycle one was 3.3, cycle two 3.5 and cycle three 3.6. Based on the interview, all students were interested in and excited about the use of the three strategies above. However, there was a problem with the implementation of peer feedback activities; it was time consuming. The results of this study can not only promote an idea for EFL teachers to use the strategies as an alternative approach to teaching speaking skills but also inspire EFL teachers to be more creative in using these three strategies

    In recent years, the demand for high-capacity communication has grown, and fiber-optic transmission is being used in wired communications to meet this demand. Similarly, free-space optics (FSO), which is an optical wireless communication technology that uses laser light, has attracted much attention and has been considered as a suitable alternative to satisfy this demand in wireless communications. Free-space optical communication uses a hundred THz frequency band and allows for high-speed and radio-regulation free transmission, which may provide a solution for the current shortage of radio frequency bands.

    To reduce the incidence of retained vaginal swabs and near misses. A review of previous retained swab incidents and near misses in a large maternity unit identified handovers and transfers as a key point of vulnerability. Interventions were introduced to improve communication at handover from the delivery suite to theatre and from theatre to the high dependency unit. Process data was collected to monitor compliance. The outcome measures were the incidence of retained swab never events and the incidence of near misses. Chi-squared analysis was used to test the significance of the results. For transfers from delivery suite to theatre, verbal handover significantly increased from 28.8% to 75.6% (ptransfers to theatre post-intervention: in 88 (30.2%) of these transfers a vaginal swab was already in situ. In 70/88 (79.5%) of cases the presence of the swab was communicated to theatre staff in three ways (verbally, written and transfer of opened swab packets) according to the new policy. In the post-intervention period there were 56 women transferred from theatre to the high-dependency unit with a vaginal pack in situ: 52 (92.9%) of these women had a sticker in place serving as a constant reminder of the presence of the vaginal pack to staff. Following a baseline of four near misses in two months, there has been only one near miss in the 15 months since the interventions were implemented, (33.3% vs. 1.1%, pcommunication at handover and transfer can reduce the incidence of retained vaginal swabs and near misses. Further work is needed to raise the profile of swab counting in maternity settings: swab counting needs to be the responsibility of all disciplines, not just the responsibility of theatre staff.

    Full Text Available This paper brings together two bodies of literature around knowledge management (KM as enterprise integration (EI and organisational ontology and epistemology as philosophy, in order to develop an extended KM approach to the development of bushfire preparedness material in the Australian context. Knowledge Management (KM in enterprise integration (EI practice manifests as process-centric electronic document and records management solutions. Knowledge creation and organisational epistemology is viewed as a social process, but this is often left unrepresented by KM processes. The body of literature on KM tends to focus on organisational functionality and organisational KM that is based on EI ontology tends to be restricted by organisational functionality and process models. We argue that developing the KM-Model using subjectivist epistemology has a significant role in KM and organisational studies for emergency and disaster agencies. As part of the Bushfire Cooperative Research Centre (CRC ‘Effective Communication and Communities’ project, bushfire communication materials were collected from all Australian States and Territories and analysed using NVivo, representing a knowledge base. Data sources including semi-structured interviews with bushfire agency staff, residents in bushfire-prone localities. Interview data was analysed using thematic analysis, and emergent themes were represented using UML as a platform independent representation of the extended knowledge domain that is capable of representation in a digital space. This work unites organisational ontology, organisational epistemology and EI; the different manifestations of KM. We theorise about how organisational epistemology itself forms as part of the knowledge, where currently there is a lacking of a satisfactory end-to-end framework. The KM lifecycle, therefore, is extended by incorporating the social research processes as part of organisational epistemology to include external

    Communication in the intensive care unit (ICU) often falls short of patient and family needs, putting them at risk for significant physical and emotional harm. As electronic patient portals rapidly evolve, one designed specifically for the ICU might potentially enhance communication among patients, family members, and clinicians; however, the views of frontline ICU staff on such technology are unknown. To identify clinician perspectives on the current state of communication among patients, families, and clinicians in the ICU, and assess their views on whether and how an electronic portal may address existing communication deficits and improve care. Three focus groups comprised altogether of 26 clinicians from 6 ICUs, representing several disciplines in an academic medical center in Boston, Massachusetts. Transcripts were analyzed inductively for major themes using grounded theory. We identified seven themes reflecting clinician perspectives on communication challenges and desired portal functionality: (1) comprehension and literacy; (2) results and updates; (3) patient and family preferences; (4) interclinician communication; (5) family informational needs; (6) the ICU as an unfamiliar environment; and (7) enhancing humanism through technology. Each theme included current gaps in practice, potential benefits and concerns related to an ICU communication portal, and participant recommendations. Benefits included enhanced education, patient/family engagement, and clinician workflow. Challenges included the stress and uncertainty of ICU care, fear of technology replacing human connection, existing interclinician communication failures, and the tension between informing families without overwhelming them. Overall, clinicians were cautiously supportive of an electronic portal to enhance communication in the ICU and made several specific recommendations for design and implementation. As new technologies expand opportunities for greater transparency and participation in

    The final structure of HfO2 films grown by atomic layer deposition (ALD) after reaction with OH- ions has been analyzed by DFT (density functional theory). The interaction of the precursors: HfCl4 (hafnium tetrachloride), HfI4 (hafnium tetraiodide), TEMA-Hf (tetrakis-ethylmethylamino hafnium), and TDMA-Hf (tetrakis-dimethylamino hafnium) with HO-H was studied employing the B3LYP (Becke 3-parameter, Lee-Yang-Parr) hybrid functional and the PBE (Perdew-Burke-Ernzerhof) generalized gradient functional. The structural evolution at the Si(100) surface has been analyzed by LDA (local density approximation). The structural parameters: bond length and bond angle, and the vibrational parameters for the optimized structures are also reported. The presence of hafnium silicate at the interface was detected. The infrared spectra and structural parameters obtained in this work agree with previously reported experimental results.

    Patients with peripheral arterial disease (PAD) have lower functional capacity and worse clinical outcomes than age and gender matched patients. Few data exist on the relationship of PAD with functional and clinical outcomes in heart failure (HF) patients. We sought to compare HF patients with and without PAD for baseline functional capacity, response to exercise training, and clinical outcomes. HF-ACTION was a randomized controlled trial comparing usual care to structured exercise training plus usual care in HF patients with an ejection fraction ≤ 35% and NYHA class II – IV heart failure symptoms. Cardiopulmonary exercise (CPX) testing occurred at enrollment, 3 months, and 1 year. Clinical follow-up occurred up to 4 years. Of the 2331 HF-ACTION patients, 157 (6.8%) had PAD. At baseline, HF patients with PAD had a lower exercise duration (8.0 vs. 9.8 minutes, p<0.001), lower peak oxygen consumption (VO2) (12.5 vs. 14.6 mL/kg/min, p<0.001), and shorter six minute walking distance (306 vs. 371 meters, p<0.001) compared to HF patients without PAD. At three months, HF patients with PAD had less improvement on CPX testing [exercise duration (0.5 vs. 1.1 minutes; p=0.002) and peak VO2 (mean change; 0.1 vs. 0.6 mL/kg/min; p=0.04)] compared to HF patients without PAD. PAD was an independent predictor of all-cause death or hospitalization [hazard ratio (95% CI); 1.31 (1.06 – 1.62), p=0.011]. PAD patients with HF have depressed baseline exercise capacity and decreased response to exercise training. In conclusion, PAD is an independent predictor of all-cause death or hospitalization in HF patients. PMID:21565325

    Multimorbidity in heart failure (HF), defined as HF of any aetiology and multiple concurrent conditions that require active management, represents an emerging problem within the ageing HF patient population worldwide. To inform this position paper, we performed: 1) an initial review of the literature identifying the ten most common conditions, other than hypertension and ischaemic heart disease, complicating the management of HF (anaemia, arrhythmias, cognitive dysfunction, depression, diabetes, musculoskeletal disorders, renal dysfunction, respiratory disease, sleep disorders and thyroid disease) and then 2) a review of the published literature describing the association between HF with each of the ten conditions. From these data we describe a clinical framework, comprising five key steps, to potentially improve historically poor health outcomes in this patient population. We identified five key steps (ARISE-HF) that could potentially improve clinical outcomes if applied in a systematic manner: 1) Acknowledge multimorbidity as a clinical syndrome that is associated with poor health outcomes, 2) Routinely profile (using a standardised protocol - adapted to the local health care system) all patients hospitalised with HF to determine the extent of concurrent multimorbidity, 3) Identify individualised priorities and person-centred goals based on the extent and nature of multimorbidity, 4) Support individualised, home-based, multidisciplinary, case management to supplement standard HF management, and 5) Evaluate health outcomes well beyond acute hospitalisation and encompass all-cause events and a person-centred perspective in affected individuals. We propose ARISE-HF as a framework for improving typically poor health outcomes in those affected by multimorbidity in HF. Copyright © 2016 The Authors. Published by Elsevier Ireland Ltd..

    To improve staff perception of the quality of the patient admission process from obstetric triage to the labor and delivery unit through standardization. Preassessment and postassessment online surveys. A 13-bed labor and delivery unit in a quaternary care, Magnet Recognition Program, academic medical center in Pennsylvania. Preintervention (n = 100), postintervention (n = 52), and 6-month follow-up survey respondents (n = 75) represented secretaries, registered nurses, surgical technicians, certified nurse-midwives, nurse practitioners, maternal-fetal medicine fellows, anesthesiologists, and obstetric and family medicine attending and resident physicians from triage and labor and delivery units. We educated staff and implemented interventions, an admission huddle and safety time-out whiteboard, to standardize the admission process. Participants were evaluated with the use of preintervention, postintervention, and 6-month follow-up surveys about their perceptions regarding the admission process. Data tracked through the electronic medical record were used to determine compliance with the admission huddle and whiteboards. A 77% reduction (decrease of 49%) occurred in the perception of incomplete patient admission processes from baseline to 6-month follow-up after the intervention. Postintervention and 6-month follow-up survey results indicated that 100% of respondents responded strongly agree/agree/neutral that the new admission process improved communication surrounding care for patients. Data in the electronic medical record indicated that compliance with use of admission huddles and whiteboards increased from 50% to 80% by 6 months. The new patient admission process, including a huddle and safety time-out board, improved staff perception of the quality of admission from obstetric triage to the labor and delivery unit.

    Postdischarge emergency department (ED) communication with family physicians is often suboptimal and negatively impacts patient care. We designed and piloted an online notification system that electronically alerts family physicians of patient ED visits and provides access to visitspecific laboratory and diagnostic information. Nine (of 10 invited) high-referring family physicians participated in this single ED pilot. A prepilot chart audit (30 patients from each family physician) determined the baseline rate of paper-based record transmission. A webbased communication portal was designed and piloted by the nine family physicians over 1 year. Participants provided usability feedback via focus groups and written surveys. Review of 270 patient charts in the prepilot phase revealed a 13% baseline rate of handwritten chart and a 44% rate of any information transfer between the ED and family physician offices following discharge. During the pilot, participant family physicians accrued 880 patient visits. Seven and two family physicians accessed online records for 74% and 12% of visits, respectively, an overall 60.7% of visits, corresponding to an overall absolute increase in receipt of patient ED visit information of 17%. The postpilot survey found that 100% of family physicians reported that they were ''often'' or ''always'' aware of patient ED visits, used the portal ''always'' or ''regularly'' to access patients' health records online, and felt that the web portal contributed to improved actual and perceived continuity of patient care. Introduction of a web-based ED visit communication tool improved ED-family physician communication. The impact of this system on improved continuity of care, timeliness of follow-up, and reduced duplication of investigations and referrals requires additional study.

    This ethnography explores communication around critically ill surgical patients in three surgical intensive care units (ICUs) in Canada. A boundary framework is used to articulate how surgeons', intensivists', and nurses' communication practices shape and are shaped by their respective disciplinary perspectives and experiences. Through 50 hours of observations and 43 interviews, these health care providers are found to engage in seven communication behaviors that either mitigate or magnify three contested symbolic boundaries: expertise, patient ownership, and decisional authority. Where these boundaries are successfully mitigated, experiences of collaborative, high-quality patient care are produced; by contrast, boundary magnification produces conflict and perceptions of unsafe patient care. Findings reveal that high quality and safe patient care are produced through complex social and cultural interactions among surgeons, intensivists, and nurses that are also expressions of knowledge and power. This enhances our understanding of why current quality improvement efforts targeting communication may be ineffective. © The Author(s) 2015.

    Interprofessional care is critical for patients at the end of life (EOL), but programs to teach communication skills to medical and nursing students are rare. The aims of this study were to determine whether an interprofessional workshop improves (1) student attitudes toward teamwork and (2) self-efficacy for communicating in difficult situations. Nursing and medical students attended a workshop with collaborative role play of an EOL conversation. Before the workshop, students showed different attitudes toward teamwork and collaboration and varying levels of confidence about communication skills. After the workshop, both groups reported more positive attitudes toward teamwork but a mixed picture of confidence in communication. Experiential interprofessional education workshops enhance perceptions about the benefits of teamwork, but further teaching and evaluation methods are needed to maximize the effectiveness. © The Author(s) 2014.

    2014-10-01

    The electroforming process of Ti/HfOx stacked RRAM devices is removed via the combination of low temperature atomic layer deposition and post metal annealing. The Pt/Ti/HfOx/Pt RRAM devices show a forming-free bipolar resistive switching behavior. By x-ray photoelectron emission spectroscopy analysis, it is found that there are many oxygen vacancies and nonlattice oxygen pre-existing in the HfOx layer that play a key role in removing the electroforming process. In addition, when the thickness ratio of the Ti and HfOx layer is 1, the uniformity of the switching parameters of Pt/Ti/HfOx/Pt devices is significantly improved. The OFF/ON window maintains about 100 at the read voltage of 0.1 V.

    As the number of patients with complex healthcare needs grows, inter-professional collaboration between primary care professionals must be constantly optimized. General practitioners (GPs) and community nurses (CNs) are key professions in primary care; however, poor GP-CN communication is common, and research into the factors influencing its quality is limited. To explore patient-related GP-CN communication and facilitating and hindering factors, and to identify strategies to enhance this communication. A qualitative focus group design was used to identify the facilitating and hindering factors and strategies for improvement. In a Dutch primary care setting, 6 mono-professional focus group interviews (3 meetings of 13 GPs; 3 meetings of 18 CNs) were organized between June 2015 and April 2016, recorded and transcribed verbatim. Two independent researchers performed the coding of these interviews, identifying their categories and themes. Results show that, despite the regular contact between GPs and CNs, communication was generally perceived as poor in effectiveness and efficiency by both professions. Mutual trust was considered the most important facilitating factor for effective communication. Profession-specific factors (e.g. differences in responsibility and profession-specific language) and organizational factors (e.g. lack of shared care plans, no in-person communication, lack of time) may be of influence on communication. Participants' suggestions for improvement included organizing well-structured and reimbursed team meetings and facilitating face-to-face contact. GP-CN patient-related communication benefits most from trusting inter-personal relationships. Inter-professional training programmes should address both professional and organizational factors and should be evaluated for their effect on quality of care.

    In this paper, we introduce an intelligent driver assistance system to reduce fuel consumption in heavy duty vehicles irrespective of the driving style of the driver. We specifically study the potential of V2I and V2V communications to reduce fuel consumption in heavy duty trucks. Most ITS communications today are oriented towards vehicle safety, with communications strategies and hardware that tend to focus on low latency. This has resulted in technologies emerging with a relatively limited range for the communications. For fuel economy, it is expected that most benefits will be derived with greater communications distances, at the scale of many hundred meters or several kilometers, due to the large inertia of heavy duty vehicles. It may therefore be necessary to employ different communications strategies for ITS applications aimed at fuel economy and other environmental benefits than what is used for safety applications in order to achieve the greatest benefits.

    High-κ HfO x N y and HfO 2 films are applied to amorphous InGaZnO (a-IGZO) devices as gate dielectric using radio-frequency reactive sputtering. The electrical characteristics and reliability of a-IGZO metal–insulator–semiconductor (MIS) capacitors and thin-film transistors (TFTs) are then investigated. Experimental results indicate that the nitrogen incorporation into HfO 2 can effectively improve the interface quality and enhance the reliability of the devices. Electrical properties with an interface-state density of 5.2 × 10 11 eV −1 cm −2 , capacitance equivalent thickness of 1.65 nm, gate leakage current density of 3.4 × 10 −5 A cm −2 at V fb +1 V, equivalent permittivity of 23.6 and hysteresis voltage of 110 mV are obtained for an Al/HfO x N y /a-IGZO MIS capacitor. Superior performance of HfO x N y /a-IGZO TFTs has also been achieved with a low threshold voltage of 0.33 V, a high saturation mobility of 12.1 cm 2 V −1 s −1 and a large on–off current ratio up to 7 × 10 7 (W/L = 500/20 µm) at 3 V

    The 178m2 Hf(16+) isomeric state has a 31-yr half life and could pose serious radioactive problems in nuclear fusion reactors if its production in 14 MeV neutron-induced reactions is significant. We present statistical/preequilibrium model calculations for the production of this isomer in the 179 Hf(n, 2n) 178m2 Hf reaction, as well as the 25-days 12.5 - isomer in the 179 Hf(n,n') 179m2 Hf reaction, using two different preequilibrium models: the exciton model and the Feshbach-Kerman-Koonin (FKK) theory. Our calculations which use the exciton model agree well with measurements, but those with the FKK theory underestimate measurements. Our calculations axe the first to probe angular momentum transfer effects in the FKK theory and suggest that, as it is presently applied, high spin-transfer reactions are underestimated. We suggest modifications to the FKK statistical averaging procedure which may result in an improved agreement with experiment

    The art of communication involves understanding the needs of the person with whom one is interacting. The radiologist must be an expediter and a consultant. Face-to-face, eyeball-to-eyeball communication is almost always best. Nonverbal communication must be aligned with verbal principles. The radiologist must build trust to have successful communication and fulfill the role of a consultant who adds value to a child's health care. This occurs most easily by increased visibility and face-to-face discussion. (orig.)

    The performance of coherent free-space optical (CFSO) communication with phase modulation is limited by both phase fluctuations and intensity scintillations induced by atmospheric turbulence. To improve the system performance, one effective way is to use digital phase estimation. In this paper, a CFSO communication system with quadrature phase-shift keying modulation is studied. With consideration of the effects of log-normal amplitude fluctuations and Gauss phase fluctuations, a two-stage Mth power carrier phase estimation (CPE) scheme is proposed. The simulation results show that the phase noise can be suppressed greatly by this scheme, and the system symbol error rate performance with the two-stage Mth power CPE can be three orders lower than that of the single-stage Mth power CPE. Therefore, the two-stage CPE we proposed can contribute to the performance improvements of the CFSO communication system and has determinate guidance sense to its actual application.

    New technology provides new possibilities to study geospace and 3D ionosphere by using spacecraft and computer simulations. A type of nanosatellites, CubeSats, provide a cost effective possibility to provide in-situ measurements in the ionosphere. Moreover, combined CubeSat observations with ground-based observations gives a new view on auroras and associated electromagnetic phenomena. Especially joint and active CubeSat - ground based observation campaigns enable the possibility of studying the 3D structure of the ionosphere. Furthermore using several CubeSats to form satellite constellations enables much higher temporal resolution. At the same time, increasing computation capacity has made it possible to perform simulations where properties of the ionosphere, such as propagation of the electromagnetic waves in the medium frequency, MF (0.3-3 MHz) and high frequency, HF (3-30 MHz), ranges is based on a 3D ionospheric model and on first-principles modelling. Electromagnetic waves at those frequencies are strongly affected by ionospheric electrons and, consequently, those frequencies can be used for studying the plasma. On the other hand, even if the ionosphere originally enables long-range telecommunication at MF and HF frequencies, the frequent occurrence of spatiotemporal variations in the ionosphere disturbs communication channels, especially at high latitudes. Therefore, study of the MF and HF waves in the ionosphere has both a strong science and technology interests. We introduce recently developed simulation models as well as measuring principles and techniques to investigate the arctic ionosphere by a polar orbiting CubeSat whose novel AM radio instrument measures HF and MF waves. The cubesat, which contains also a white light aurora camera, is planned to be launched in late 2017 (http://www.suomi100satelliitti.fi/eng). The new models are (1) a 3D ray tracing model and (2) a 3D full kinetic electromagnetic simulation. We also introduce how combining of the

    As shown in the famous EPR paper (Einstein, Podolsky e Rosen, 1935), Quantum Mechanics is non-local. The Bell theorem and the experiments by Aspect and many others, ruled out the possibility of explaining quantum correlations between entangled particles using local hidden variables models (except for implausible combinations of loopholes). Some authors (Bell, Eberhard, Bohm and Hiley) suggested that quantum correlations could be due to superluminal communications (tachyons) that propagate isotropically with velocity v t > c in a preferred reference frame. For finite values of v t , Quantum Mechanics and superluminal models lead to different predictions. Some years ago a Geneva group and our group did experiments on entangled photons to evidence possible discrepancies between experimental results and quantum predictions. Since no discrepancy was found, these experiments established only lower bounds for the possible tachyon velocities v t . Here we propose an improved experiment that should lead us to explore a much larger range of possible tachyon velocities V t for any possible direction of velocity V-vector of the tachyons preferred frame.

    2017-06-01

    Full Text Available In this paper, chaos based interleavers are proposed for the performance improvement of Interleave Division Multiple Access (IDMA henceforth for future radio communication (FRC requirements. ‘IDMA’ can be mean as the modified case of direct sequence code division multiple access (DS-CDMA with the same spreading sequences and user specific interleavers for distinguishing the users in multi-user environment. In IDMA systems, the roles of interleavers are pre-eminent and an efficient interleaver contributes in optimizing the system performance. Random interleaver is the popular and basic taxonomy in IDMA. The performance of chaos based interleavers is compared to random interleaver. Simulation results authenticate the performance of chaos based IDMA. Further the proposed chaotic map-interleavers have the less computational complexity and efficient in bandwidth compared to the existing prevailing interleaver algorithms in the domain. The IDMA system model uses a BPSK modulation and repetition coder with a code rate of ½. The system is simulated in MATLAB and results show the BER superiority of chaotic interleaver based IDMA without the need of extra storage resources and less computational complexity.

    The application of digital image processing to improve man-machine communication in a nuclear reactor control room is illustrated. At the Hanford N Reactor, operated by UNC Nuclear Industries for the United States Department of Energy, in Richland, Washington, digital image processing is applied to flow, temperature, and tube power data. Color displays are used to present the data in a clear and concise fashion. Specific examples are used to demonstrate the capabilities and benefits of digital image processing of reactor data. N Reactor flow and power maps for routine reactor operations and for perturbed reactor conditions are displayed. The advantages of difference mapping are demonstrated. Image processing techniques have also been applied to results of analytical reactor models; two examples are shown. The potential of combining experimental and analytical information with digital image processing to produce predictive and adaptive reactor core models is discussed. The applications demonstrate that digital image processing can provide new more effective ways for control room personnel to assess reactor status, to locate problems and explore corrective actions. 10 figures

    The magnetic hyperfine fields at 181 Ta ion-probe sites in the HfFe 2 polycrystalline binary compound were measured using the time-differential perturbed angular correlation (TDPAC) method. Measurements were performed in the absence of polarizing external magnetic field, at room temperature. The existence of two different structures, dominant cubic MgCu 2 -type and hexagonal MgZn 2 -type in our HfFe 2 sample was refined. Both structures are ferromagnetic with Curie temperatures, which differ significantly (588 K for MgCu 2 and 427 K for MgZn 2 ). The corresponding values of hyperfine fields are H hf 13.8±0.1 T for MgCu 2 -type structure and H hf = 8.0±0.2 T for MgZn 2 -type structure. Calculations using LAPW-Wien 97 program package are in progress and preliminary results are in good agreement with experiment. The analysis includes qualitative explanation of the exchange interactions mechanism between magnetic dipole moment of the observed 181 Ta ion-probe and magnetic dipole moments of the nearest neighbours on the corresponding coordination polyhedra. All these results will be published recently. (author)

    Communication is increasingly recognized as a core skill for veterinary practitioners, and in recent years, attention to communication competency and skills training has increased. To gain an up-to-date assessment of the current state of veterinary communication skills and training, we conducted a survey among veterinary practitioners in the United Kingdom and United States in 2012/2013. The questionnaire was used to assess the current state, relevance, and adequacy of veterinary communication skills among veterinary practitioners, to assess interest in further training, and to understand perceived challenges in communicating with clients. There was an overall response rate of 29.6% (1,774 of 6,000 recipients), with a higher response rate for UK-based practitioners (39.7%) than practitioners in the US (19.5%). Ninety-eight percent of respondents agreed that communication skills were as important as or more important than clinical knowledge. Forty-one percent of respondents had received formal veterinary communication skills training during veterinary school, and 47% had received training post-graduation. Thirty-five percent said their veterinary communication skills training during veterinary school prepared them well or very well for communicating with clients about the health of their pets, compared to 61% of those receiving post-graduate training. Forty percent said they would be interested in further veterinary communication skills training, with the preferred methods being simulated consultations and online training. While there has been increased emphasis on communication skills training during and after veterinary school, there is a need for more relevant and accessible training.

    Nurses function as central figures of health teams, coordinating direct care and communication between team members, patients, and their families. The importance of nurses to health care cannot be understated, but neither can the environmental struggles nurses routinely encounter in their jobs. Organizational communication and nursing scholarship show conflict and stress as two visible and ongoing challenges. This case study aims to (a) explore the ways conflict communication and communicative stress are experienced and endure in nursing and (b) understand how nurses discursively (mis)manage conflict and stress. Open-ended survey comments from nurses (N = 135) employed at a large teaching and research hospital were qualitatively analyzed. Weick's model of organizing, specifically his notion of communication cycles, emerged as a conceptual lens helpful for understanding cyclical conflict and stress. Results show that exclusionary communication, specifically nonparticipatory and unsupportive messages, contribute to nurse conflict and stress. Nurses tend to (mis)manage conflict and stress using respectful and disrespectful discourse. These communication patterns can facilitate or prohibit positive change. Metaphorically, nurse communicative conflict and stress can be depicted as fire. Relationships can go up in flames due to out-of-control fires in the form of destructive conflict. However, conflict and stress, like fire, can be harnessed for positive ends such as organizational decision making and innovation. Findings suggest conveying respect may help nurses manage and even avoid flames of conflict and stress. Solutions are offered to mitigate the effects of conflict and stress while developing respectful organizational cultures.

    This paper presents an exploratory case study of clinician-patient communications in a specific clinical environment. It describes how intensive care unit (ICU) clinicians' technical and social categorizations of patients and families shape the flow of communication in these acute care settings. Drawing on evidence from a year-long ethnographic study of four ICUs, we develop a typology of patients and families as viewed by the clinicians who care for them. Each type, or category, of patient is associated with differing communication strategies, with compliant patients and families engaged in greater depth. In an era that prioritizes patient engagement through communication for all patients, our findings suggest that ICU teams need to develop new strategies for engaging and communicating with not just compliant patients and families, but those who are difficult as well. We discuss innovative methods for developing such strategies.

    Patient-physician communication should be based on plain and simple language. Despite communication skill trainings in undergraduate medical curricula medical students and physicians are often still not aware of using medical jargon when communicating with patients. The aim of this study was to compare linguistic communication skills of undergraduate medical students who voluntarily translate medical documents into plain language with students who do not participate in this voluntary task. Fifty-nine undergraduate medical students participated in this study. Twenty-nine participants were actively involved in voluntarily translating medical documents for real patients into plain language on the online-platform https://washabich.de (WHI group) and 30 participants were not (non-WHI group). The assessment resembled a virtual consultation hour, where participants were connected via skype to six simulated patients (SPs). The SPs assessed participants' communication skills. All conversations were transcribed and assessed for communication skills and medical correctness by a blinded expert. All participants completed a self-assessment questionnaire on their communication skills. Across all raters, the WHI group was assessed significantly (p = .007) better than the non-WHI group regarding the use of plain language. The blinded expert assessed the WHI group significantly (p = .018) better regarding the use of stylistic devices of communication. The SPs would choose participants from the WHI group significantly (p = .041) more frequently as their personal physician. No significant differences between the two groups were observed with respect to the medical correctness of the consultations. Written translation of medical documents is associated with significantly more frequent use of plain language in simulated physician-patient encounters. Similar extracurricular exercises might be a useful tool for medical students to enhance their communication skills with

    Background: Radiographers can have a marked impact on the way patients deal with their illness because they are often one of the first health professionals that patients see. Therefore, it is essential that radiographers have effective communication skills and are able to provide patients with the information they require. The purpose of this study was to test whether the introduction of additional education on communication and history taking improved students' communication skills. Methods: A short program on communication skills and history taking was introduced to third year undergraduate students prior to a clinical placements period. Three workshops were run; the third included a role play exercise using professional actors as simulated patients. Students completed questionnaires at baseline, following the three workshops and after their subsequent clinical placement. Descriptive statistics were calculated and logistic regression Generalized Estimating Equations models were fitted to test for differences over time in students' confidence levels. Results: Twenty-seven out of 36 students completed the baseline and final surveys. Students indicated they were highly satisfied with the workshops provided. Statistically significant differences were observed for seven items relating to student's confidence levels in communicating with patients after they had participated in the workshops and their subsequent clinical placement. Conclusion: The use of communication skills workshops involving actor/patients is an effective method of assisting students to develop their communication and history taking skills. This program has now been implemented into the mentioned undergraduate course and it is recommended that radiography students at other institutions be provided with the opportunity to develop their communication and history taking skills.

    Full Text Available Communication between management and employees is very important in organizations. However, communication problems might be more felt in any media organization as a whole and in the local media staff in particular. It’s obvious that news workers have everyday communicative interaction with different newsmakers. The article deals with the study and analysis of the communicative interaction between the local editorial creative staff members. Internal and external organizational understanding data are considered. It is determined that the level of organizational communication development influences the local editorial success and employees’ performance. Mutual understanding as the basic criterion of effective communication has several forms. The subject of our study is organizational understanding, that is, a special type of editorial staff relationship which is limited by the boundaries of the organization and is essential for its successful functioning and development. The analysis of empirical data allowed to identify the main problematic aspects and to work out the recommendations for vertical and horizontal communication development.

    Traditional communication theory and research methods provide valuable guidance about designing and evaluating health communication programs. However, efforts to use health communication programs to educate, motivate, and support people to adopt healthy behaviors often fail to meet the desired goals. One reason for this failure is that health promotion issues are complex, changeable, and highly related to the specific needs and contexts of the intended audiences. It is a daunting challenge to effectively influence health behaviors, particularly culturally learned and reinforced behaviors concerning lifestyle factors related to diet, exercise, and substance (such as alcohol and tobacco) use. Too often, program development and evaluation are not adequately linked to provide rapid feedback to health communication program developers so that important revisions can be made to design the most relevant and personally motivating health communication programs for specific audiences. Design science theory and methods commonly used in engineering, computer science, and other fields can address such program and evaluation weaknesses. Design science researchers study human-created programs using tightly connected build-and-evaluate loops in which they use intensive participatory methods to understand problems and develop solutions concurrently and throughout the duration of the program. Such thinking and strategies are especially relevant to address complex health communication issues. In this article, the authors explore the history, scientific foundation, methods, and applications of design science and its potential to enhance health communication programs and their evaluation.

    Resistive random access memory (ReRAM) devices with a HfO2 dielectric layer have been studied extensively owing to the good reproducibility of their SET/RESET switching properties. Furthermore, it was reported that a thin Hf layer next to a HfO2 layer stabilized switching properties because of the oxygen scavenging effect. In this work, we studied the Hf thickness dependence of the resistance switching characteristics of a Ti/Hf/HfO2/Au ReRAM device. It is found that the optimum Hf thickness is approximately 10 nm to obtain good reproducibility of SET/RESET voltages with a small RESET current. However, when the Hf thickness was very small (∼2 nm), the device failed after the first RESET process owing to the very large RESET current. In the case of a very thick Hf layer (∼20 nm), RESET did not occur owing to the formation of a leaky dielectric layer. We observed the occurrence of multiple resistance states in the RESET process of the device with a Hf thickness of 10 nm by increasing the RESET voltage stepwise.

    In order to improve the electrochemical performance of the positive graphite felt electrode in vanadium flow redox battery, a novel method is developed to effectively modify the graphite felt by combination of etching of HF and oxidation of H2O2. After the etching of HF for the graphite felt at ambient temperature, abundant oxygen-containing functional groups were further introduced on the surface of graphite felt by hydrothermal treatment using H2O2 as oxidant. Benefiting from the surface etching and introduction of functional groups, mass transfer and electrode process can be improved significantly on the surface of graphite felt. VO2+/VO2+ redox reaction on the graphite felt modified by HF and H2O2 jointly (denote: GF-HF/H2O2) exhibits superior electrochemical kinetics in comparison with the graphite felt modified by single HF or H2O2 treatment. The cell using GF-HF/H2O2 as the positive electrode was assembled and its electrochemical properties were evaluated. The increase of energy efficiency of 4.1% for GF-HF/H2O2 at a current density of 50 mA cm-2 was obtained compared with the pristine graphite felt. The cell using GF-HF/H2O2 also demonstrated higher discharge capacity. Our study revealed that HF/H2O2 treatment is an efficient method to enhance the electrochemical performance of graphite felt, further improving the comprehensive energy storage performance of the vanadium flow redox battery.

    Full Text Available Background: Communication is a process that allows us to interact with other people. Medical professionals need to possess good communication skills for history taking, diagnosis, and treatment. Communicative skills are hardly taught in medical schools of India. The students are expected to learn them on their own. To address this issue, we introduced communicative skills training (CST for medical interns. Objective: Primary – To determine the effectiveness of CST in improving history taking on sensitive issues by medical interns. Secondary – To improve patients' satisfaction through improved communicative skills. Materials and Methods: This was a randomized control study carried out on medical interns at Jamnagar. The interns were randomized to either Group A or Group B. Intervention in the form of CST was given to Group A while Group B was control. The topic of CST was “eliciting sexual history.” Assessment of participants was done by pre- and post-intervention objective structured clinical examination. For ethical reasons, Group B was also given CST by experts after completion of our study but their results were not included for analysis. Results: Although mean scores increased in both the groups, (from 6.4 to 13.4 in the intervention group and from 6.5 to 7.5 in controls, the percent increase was much larger in the intervention group than controls (109% vs. 15%. Students gave a positive feedback to CST. Opinion of teachers was favoring CST. Among the patients allotted to intervention group, 83% were satisfied. Conclusion: CST imparted to medical interns helps in improving doctor–patient relationship.

    Health care providers must effectively function in highly skilled teams in a collaborative manner, but there are few interprofessional training strategies in place. Interprofessional education (IPE) using simulation technology has gained popularity to address this need because of its inherent ability to impact learners' cognitive frames and promote peer-to-peer dialog. Provider attitudes toward teamwork have been directly linked to the quality of patient care. Investigators implemented a simulation-enhanced IPE intervention to improve staff attitudes toward teamwork and interprofessional communication in the emergency department setting. The 3-hour course consisted of a didactic session highlighting teamwork and communication strategies, 2 simulation scenarios on septic shock and cardiac arrest, and structured debriefing directed at impacting participant attitudes to teamwork and communication. This was a survey-based observational study. We used the TeamSTEPPS Teamwork Attitudes Questionnaire immediately before and after the session as a measurement of attitude change as well as the Hospital Survey on Patient Safety Culture before the session and 1 year after the intervention for program impact at the behavior level. Seventy-two emergency department nurses and resident physicians participated in the course from July to September 2012. Of the 5 constructs in TeamSTEPPS Teamwork Attitudes Questionnaire, 4 had a significant improvement in scores-6.4%, 2.8%, 4.0%, and 4.0% for team structure, leadership, situation monitoring, and mutual support, respectively (P teamwork and communication showed a significant improvement-20.6%, 20.5%, and 23.9%, for frequency of event reporting, teamwork within hospital units, and hospital handoffs and transitions, respectively (P = 0.028, P = 0.035, and P = 0.024, respectively).

    During the past two years, significant steps have been made in Europe for achieving the needed accessibility to High Frequency Radar (HFR) data for a pan-European use. Since 2015, EuroGOOS Ocean Observing Task Teams (TT), such as HFR TT, are operational networks of observing platforms. The main goal is on the harmonization of systems requirements, systems design, data quality, improvement and proof of the readiness and standardization of HFR data access and tools. Particular attention is being paid by HFR TT to converge from different projects and programs toward those common objectives. First, JERICO-NEXT (Joint European Research Infrastructure network for Coastal Observatory - Novel European eXpertise for coastal observaTories, H2020 2015 Programme) will contribute on describing the status of the European network, on seeking harmonization through exchange of best practices and standardization, on developing and giving access to quality control procedures and new products, and finally on demonstrating the use of such technology in the general scientific strategy focused by the Coastal Observatory. Then, EMODnet (European Marine Observation and Data Network) Physics started to assemble HF radar metadata and data products within Europe in a uniform way. This long term program is providing a combined array of services and functionalities to users for obtaining free of charge data, meta-data and data products on the physical conditions of European sea basins and oceans.

    This paper explores risk communications concepts that could be used by Federal and state governments to help the public understand how government officials rely on risk analysis and management to ensure that shipments of spent fuel and other radioactive wastes take place in a safe, secure manner that merits public confidence. A key focus in the communication concepts put forward in the paper is the relationship between understanding and validating the public's concerns and explaining how those concerns are being addressed by current safety requirements and practices. The authors will recommend best practices to state and Federal officials that have the responsibility for communicating with the public about radioactive waste transportation. The paper will also suggest ways to bring these state and federal co-regulators together to communicate more effectively and to speak with one voice on the issue of shipment safety. (authors)

    Although the use of telepractice in speech-language therapy for assessment purposes is well documented, its effectiveness and potential for rehabilitation in poststroke aphasia remain largely unknown. The purpose of this study was to investigate the effectiveness of a remotely delivered synchronous pragmatic telespeech language therapy for improving functional communication in aphasia. A pre-/post-test design was chosen in which each participant was his or her own control. Using a telerehabilitation platform and software (Oralys TeleTherapy) based on the Promoting Aphasics' Communicative Effectiveness (PACE) approach, 20 participants with chronic poststroke aphasia received 9 speech therapy sessions over a 3-week period. Teletreatment with the PACE pragmatic rehabilitation approach led to improvements in functional communication, marked by (a) an increase in communication effectiveness, reflecting significantly improved autonomy in functional communication; (b) a decrease in communication exchange duration, meaning that the treatment made communication faster and more efficient; (c) a decrease in the number of communication acts, meaning that, after treatment, less information was needed to be efficiently understood by the communication partner; and (d) an increase in the number of different communication strategies used, meaning that the treatment fostered the use of a variety of alternative communication modes. This study provides additional arguments about the benefits of telerehabilitation for poststroke patients with aphasia. It showed that multimodal language therapy delivered through synchronous telerehabilitation had positive effects on functional communication in chronic aphasia.

    To enhance the efficiency of eavesdropping detection in the quantum secure direct communication protocol, an improved quantum secure direct communication protocol based on a four-particle Green-Horne-Zeilinger (GHZ) state is presented. In the protocol, the four-particle GHZ state is used to detect eavesdroppers, and quantum dense coding is used to encode the message. In the security analysis, the method of entropy theory is introduced, and two detection strategies are compared quantitatively by using the constraint between the information that the eavesdroppers can obtain and the interference that has been introduced. If the eavesdropper wants to obtain all the information, the detection rate of the quantum secure direct communication using an Einstein-Podolsky-Rosen (EPR) pair block will be 50% and the detection rate of the presented protocol will be 87%. At last, the security of the proposed protocol is discussed. The analysis results indicate that the protocol proposed is more secure than the others. (orig.)

    Family caregivers of cancer patients have a vital role in facilitating and sharing information about cancer, revealing a need to develop caregiver health literacy skills to support caregiver communication. The goal of this study was to investigate caregiver print materials and develop and assess a new caregiver communication resource titled A Communication Guide for Caregivers TM . Using a model of six domains of caregiver health literacy skills, print cancer education materials were collected and evaluated for caregiver communication support. A new caregiver communication resource was also developed and assessed by caregivers and healthcare providers. Caregivers reviewed content and assessed utility, relatability, and reading quality. Healthcare providers also assessed whether the material would be understandable and usable for cancer caregivers. Only three of the 28 print materials evaluated were written at the recommended sixth grade reading level and only five addressed all six caregiver health literacy skills. Readability scores for A Communication Guide for Caregivers TM were at the sixth grade level, and caregivers reported its contents were relatable, useful, and easy to read. Healthcare providers also rated the material as easy for patient/family members of diverse backgrounds and varying levels of literacy to understand and use. Existing print-based caregiver education materials do not address caregivers' health literacy skill needs and are aimed at a highly literate caregiving population. A Communication Guide for Caregivers TM meets health literacy standards and family caregiver and provider communication needs. The findings are relevant for healthcare professionals who provide cancer education. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Communication failures in healthcare teams are associated with medical errors and negative health outcomes. These findings have increased emphasis on training future health professionals to work effectively within teams. The Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) communication training model, widely employed to train healthcare teams, has been less commonly used to train student interprofessional teams. The present study reports the effectiveness of a simulation-based interprofessional TeamSTEPPS training in impacting student attitudes, knowledge and skills around interprofessional communication. Three hundred and six fourth-year medical, third-year nursing, second-year pharmacy and second-year physician assistant students took part in a 4 h training that included a 1 h TeamSTEPPS didactic session and three 1 h team simulation and feedback sessions. Students worked in groups balanced by a professional programme in a self-selected focal area (adult acute, paediatric, obstetrics). Preassessments and postassessments were used for examining attitudes, beliefs and reported opportunities to observe or participate in team communication behaviours. One hundred and forty-nine students (48.7%) completed the preassessments and postassessments. Significant differences were found for attitudes toward team communication (pteam structure (p=0.002), situation monitoring (pteams (pteam communication is important in patient safety. We demonstrate positive attitudinal and knowledge effects in a large-scale interprofessional TeamSTEPPS-based training involving four student professions.

    Using a tracer technique, self-diffusion of Er and Hf was measured over the approximate temperature interval of 1600 to 1970 0 C in pure and HfO 2 -doped polycryatalline Er 2 O 3 . Up to about 10 m/o HfO 2 dopant level, the Er self-diffusion coefficients followed a relationship based on cation vacancies. Above 10 m/o HfO 2 , deviation from this relationship occurred, apparently due to clustering of cation vacancies and oxygen interstitials around the dopant hafnia ion. The activation energy for the self-diffusion of Er in pure Er 2 O 3 was 82.2 Kcal/mole and increased with the HfO 2 dopant level present. Self-diffusion of Hf was measured in pure Er 2 O 3 having two impurity levels, and a separation of the grain boundary. The volume diffusion of Hf showed both extrinsic and intrinsic behavior with the transition temperature increasing with the impurity level present in Er 2 O 3 . The activation energy for Hf volume diffusion in the intrinsic region was high, i.e. 235 -+ 9.5 Kcal/mole. The grain boundary diffusion was apparently extrinsic over the entire temperature interval Very low Hf self diffusion rates were found in both pure and HfO 2 doped Er 2 O 3 compositions. Despite a clustering effect, the HfO 2 dopant increased the Hf volume diffusion coefficients

    Communication between university medical centers and general practitioners (GP) is becoming increasingly more important in supportive patient care. A survey among GPs was performed with the primary objective to assess their opinion on current workflow and communication between GPs and the university medical center. The GPs were asked to score (grades 1-6) their opinion on the current interdisciplinary workflow in the care of patients with brain tumors, thereby rating communication between a university medical center in general and the neuro-oncology outpatient center in particular. Questionnaires were sent to1000 GPs and the response rate was 15 %. The mean scored evaluation of the university medical center in general was 2.62 and of the neuro-oncological outpatient clinic 2.28 (range 1-6). The most often mentioned issues to be improved were easier/early telephone information (44 %) and a constantly available contact person (49 %). Interestingly, > 60 % of the GPs indicated they would support web-based tumor boards for interdisciplinary and palliative neuro-oncological care. As interdisciplinary care for neuro-oncology patients is an essential part of therapy, improvement of communication between GPs and university medical centers is indispensable. Integrating currently available electronic platforms under data protection aspects into neuro-oncological palliative care could be an interesting tool in order to establish healthcare networks and could find acceptance with GPs.

    Impacts of post-metallization annealing (PMA) on bipolar resistance switching of Ti/HfO x stacked films were investigated. A Ti capping film as a scavenging layer with assistance of PMA is used to tune the dielectric strength of the 10-nm-thick HfO x layer. The polycrystalline microstructure of 10-nm-thick HfO x seems immune to the temperature of PMA in this work. The initial resistance and forming voltage in the Ti/HfO x devices mitigate as the increment of the annealing temperature. With enough annealing temperature (>450 °C), the device shows a good on/off ratio, high temperature operation ability and robust endurance (>10 6 cycles). Through the reaction between Ti and HfO x at 500 °C, the abundant oxygen ions are depleted from the insulator and the left charge-defects building conductive percolative paths in the dielectric layer. The operation-polarity independence of the form-free HfO x device in initial state is demonstrated. The forming-free memory with initial low resistance of 800 Ω at 0.1 V can be operated with stable bipolar resistance switching via initially positive or negative voltage sweep. The formless device with 10 nm thick HfO x also exhibits excellent nonvolatile memory performances, including enough on/off ratio, improved HRS uniformity and good high temperature retention (3 × 10 4 s at 200 °C). The results of this work suggest that the PMA temperature will affect the memory window and cycling reliability of the Ti/HfO x -based resistive memory. Optimum temperature (450 °C) will improve the memory performance of the Ti/HfO x stacked layer. (paper)

    Preliminary study of data blending of surface current for Sunda Strait-Indonesia has been done using the analysis scheme of the Ensemble Transform Kalman Filter (ETKF). The method is utilized to combine radial velocity from HF Radar and u and v component of velocity from Global Copernicus - Marine environment monitoring service (CMEMS) model. The initial ensemble is based on the time variability of the CMEMS model result. Data tested are from 2 CODAR Seasonde radar sites in Sunda Strait and 2 dates such as 09 September 2013 and 08 February 2016 at 12.00 UTC. The radial HF Radar data has a hourly temporal resolution, 20-60 km of spatial range, 3 km of range resolution, 5 degree of angular resolution and spatial resolution and 11.5-14 MHz of frequency range. The u and v component of the model velocity represents a daily mean with 1/12 degree spatial resolution. The radial data from one HF radar site is analyzed and the result compared to the equivalent radial velocity from CMEMS for the second HF radar site. Error checking is calculated by root mean squared error (RMSE). Calculation of ensemble analysis and ensemble mean is using Sangoma software package. The tested R which represents observation error covariance matrix, is a diagonal matrix with diagonal elements equal 0.05, 0.5 or 1.0 m2/s2. The initial ensemble members comes from a model simulation spanning a month (September 2013 or February 2016), one year (2013) or 4 years (2013-2016). The spatial distribution of the radial current are analyzed and the RMSE values obtained from independent HF radar station are optimized. It was verified that the analysis reproduces well the structure included in the analyzed HF radar data. More importantly, the analysis was also improved relative to the second independent HF radar site. RMSE of the improved analysis is better than first HF Radar site Analysis. The best result of the blending exercise was obtained for observation error variance equal to 0.05 m2/s2. This study is

    Mobile device technology has revolutionized interpersonal communication, but the application of this technology to the physician-patient relationship remains limited due to concerns over patient confidentiality and the security of digital information. Nevertheless, there is a continued focus on improving communication between doctors and patients in all fields of medicine as a means of improving patient care. In this study, we implement a novel communications platform to demonstrate that instantaneously sharing perioperative information with surgical patients and members of their support networks can improve patient care and strengthen the physician-patient relationship. 423 consecutive patients scheduled to undergo elective surgical procedures were offered complimentary registration to a secure, web-based service designed to distribute perioperative updates to a group of recipients designated by each patient via Short Message Service (SMS) and/or email. Messages were created by attending surgeons and delivered instantaneously through the web-based platform. In the postoperative period, patients and their designated message recipients, as well as participating healthcare providers, were asked to complete a survey designed to assess their experience with the messaging system. Survey results were statistically analyzed to determine satisfaction rates. Of the qualifying 423 patients, 313 opted to enroll in the study. On average, patients selected a total of 3.5 recipients to receive perioperative updates. A total of 1,195 electronic messages were generated for distribution to designated recipients during the study period and delivered to recipients located around the world. There were no documented errors or failures in message delivery. Satisfaction surveys were completed by 190 users of the service (73 %). Respondents identified themselves as either patients (n = 48, 25.5 %), family/friends (n = 120, 63.8 %), or healthcare providers (n = 15, 12

    With the number of people with sight loss predicted to double to four million people in the UK by the year 2050, preventable visual loss is a significant public health issue. Sight loss is associated with an increased risk of falls, accidents and depression and evidence suggests that 50% of sight loss can be avoided. Timely diagnosis is central to the prevention of sight loss. Access to care can be a limiting factor in preventable cases. By improving referrals and access to hospital eye services it is possible to treat and minimise the number of patients with preventable sight loss and the impact this has on wider society. In 2005, NHS Fife took part in a flagship pilot funded by the Scottish government e-health department to evaluate the feasibility, safety, clinical effectiveness, and cost of electronic referral with images of patients directly from community optometrists to Hospital Eye Service (HES). The pilot study showed that electronic referral was feasible, fast, safe, and obviated the need for outpatient appointments in 128 (37%) patients with a high patient satisfaction. The results of the pilot study were presented and in May 2007, the electronic referral system was rolled out regionally in southeast Scotland. Referrals were accepted at a single site with vetting by a trained team and appointments were allocated within 48 hours. Following the implementation of electronic referral, waiting times were reduced from a median of 14 to 4 weeks. Significantly fewer new patients were seen (7462 vs 8714 [p electronic communication between community optometry practices and hospital eye departments. Five electronic forms were specifically designed for cataract, glaucoma, macula, paediatric and general ophthalmic disease. A Virtual Private Network was created which enabled optometrists to connect to the Scottish clinical information gateway system and send referrals to hospital and receive referral status feedback. Numerous hurdles have been encountered and overcome

    Full Text Available Effective information management is a success factor for business growth, but small and medium-sized enterprises (SMEs face challenges in transferring knowledge and information from one organizational unit to another. In this study of two case companies, participative business model development processes were designed to identify challenges and solutions in internal communication management. A service design approach based on CIMO logic (context, intervention, mechanism, and output showed that the participative business model technique and process can identify problems and challenges in internal communication management, as well as in the prioritization of actions. The process is a creative service design process including both divergent and convergent phases. The process increased motivation among personnel to find solutions, encouraged communication, and created joint understanding on how to solve problems. The technique helped to bring tacit information into use.

    Digital communication between government and citizens is pivotal to e-government. The Danish e-government initiative Digital Post aims to digitize all communications between government and citizens. We surveyed local government staff about how Digital Post affects the service delivered to citizens....... As much as 82% of the 448 respondents considered digital communication with citizens using Digital Post a good idea, yet 47% reported concrete incidents in which they perceived a decrease in service with Digital Post. This result shows the importance of distinguishing between the overall service...... relationship and the concrete incidents of which the service consists. We discuss interactions between the relationship level and the incident level of Digital Post on the basis of a content analysis of the respondents' incident descriptions....

    Full Text Available In an economy with a strong concurential character, organizations must capitalize the integrated marketing communication in the most effective way, to ensure the creation and maintenance of long-term relationships with current and potential customers. Building and managing the relationships with customers can have a direct and favourable effect on the efficiency of an organization's communication efforts. The integrated marketing communication identifies with the nowadays market dynamics and learns the organizations how easy can be to prosper in an environment where changes occur in an alarming way. Therefore, the purpose of this paper is to analyze the socio-demographic profile of the consumers of bread in Arges County, as well as the preferences and purchasing behaviour at the level of the market segments identified using the K-Means Cluster Analysis method.

    1998-01-01

    Policy makers, health care providers, and the general public need valid information about the benefits and harmful effects of drugs and technologies to be able to make rational choices in their acquisition, distribution, and use. Effective communication is important for quality choices of drugs and other technologies. In effective communication, the choice of messages and media must correspond to the culture and beliefs of the target groups to make them comprehend and adopt the conclusions. Messages must be presented on a regular basis. Most regulatory agencies do not have enough resources to mount effective communication programs. Private advertising agencies and other stakeholders have definite roles. Valid knowledge must be the basis of dialogues to reduce emotional disputes among various benefit groups in society.

    This systematic review examines the effectiveness of communication technology interventions on HPV vaccination initiation and completion. A comprehensive search strategy was used to identify existing randomized controlled trials testing the impact of computer-, mobile- or internet-based interventions on receipt of any dose of the HPV vaccine. Twelve relevant studies were identified with a total of 38,945 participants. The interventions were delivered using several different methods, including electronic health record (i.e. recall/reminder) prompts, text messaging, automated phone calls, interactive computer videos, and email. Vaccine initiation and completion was greater for technology-based studies relative to their control conditions. There is evidence that interventions utilizing communication technologies as their sole or primary mode for HPV vaccination intervention delivery may increase vaccination coverage. Communication technologies hold much promise for the future of HPV vaccination efforts, especially initiatives in practice-based settings. Copyright © 2017 Elsevier B.V. All rights reserved.

    2014-01-01

    Full Text Available Since 2010 a 2nd generation NOAA MF/HF radar, also referred to as the VIPIR ionosonde, has been operated at Hualien, Taiwan (23.8973°N, 121.5503°E. The Hualien VIPIR ionosonde is a modern ionospheric radar, fully digitizing complex signal records and using multiple parallel receiver channels for simultaneous signal measurements from multiple spaced receiving antennas. This paper considers radio direction finding based on interferometric phase measurements from a horizontal antenna array in the Hualien VIPIR ionosonde system. We applied the Hermite normal form method to solve the phase-measurement aliasing and least squares problems and improve the radio angle-of-arrival (AOA measurements. Backward ray-tracing simulation has been proposed to determine radio transmitter position. This paper presents a numerical, step by step ray-tracing method based on the IGRF superimposed onto a phenomenological ionospheric electron density model, the TaiWan Ionospheric Model (TWIM. The proposed methodology is successfully applied to locate two experimental HF radio transmitters at Longquan and Chungli with distance errors within 5 km and less than 5% of the great circle distances.

    2016-07-01

    Background Communication, particularly transmission of information between the surgical and nursing teams, has been identified as one of the most crucial determinants of patient outcomes. Nonetheless, transfer of information among and between the physician and nursing teams in the immediate postoperative period is often informal, verbal, and inconsistent. Methods An iterative process of multidisciplinary information gathering was undertaken to create a novel postoperative communication system (the "Pop-form"). Once developed, nurses were surveyed on multiple measures regarding the perceived likelihood that it would improve their ability to provide directed patient care. Data were quantified using a Likert scale (0-10), and statistically analyzed. Results The Pop-form records and transfers operative details, specific anatomic monitoring parameters, and senior physician contact information. Sixty-eight nurses completed surveys. The perceived usefulness of different components of the Pop-form system was as follows: 8.9 for the description of the procedure; 9.3 for the operative diagram; 9.4 for the monitoring details and parameters; and 9.4 for the direct contact information for the appropriate surgical team member. All respondents were in favor of widespread adoption of the Pop-form. Conclusion This uniform, visual communication system requires less than 1 minute to compose, yet formalizes and standardizes inter-team communication, and therefore shows promise for improving outcomes following microvascular free tissue transfer. We believe that this simple, innovative communication tool has the potential to be more broadly applied to many other health care settings.

    Failure to follow up and communicate test results to patients in outpatient settings may lead to diagnostic and therapeutic delays. Residents are less likely than attending physicians to report results to patients, and may face additional barriers to reporting, given competing clinical responsibilities. This study aimed to improve the rates of communicating test results to patients in resident ambulatory clinics. We performed an internal medicine, residency-wide, pre- and postintervention, quality improvement project using audit and feedback. Residents performed audits of ambulatory patients requiring laboratory or radiologic testing by means of a shared online interface. The intervention consisted of an educational module viewed with initial audits, development of a personalized improvement plan after Phase 1, and repeated real-time feedback of individual relative performance compared at clinic and program levels. Outcomes included results communicated within 14 days and prespecified "significant" results communicated within 72 hours. A total of 76 of 86 eligible residents (88%) reviewed 1713 individual ambulatory patients' charts in Phase 1, and 73 residents (85%) reviewed 1509 charts in Phase 2. Follow-up rates were higher in Phase 2 than Phase 1 for communicating results within 14 days and significant results within 72 hours (85% versus 78%, P  Communication of "significant" results was more likely to occur via telephone, compared with communication of nonsignificant results. Participation in a shared audit and feedback quality improvement project can improve rates of resident follow-up and communication of results, although communication gaps remained.

    Ceramic materials based on pure barium hafnate (BaHfO_3) have been obtained as a powder by the co-precipitation method. The powders obtained have a cubic structure that favors the thermoluminescent and optical properties, through which a better detection of the non-ionizing radiation is allowed. With these powders various tests were performed in the ultraviolet range at different exposure times. These thermoluminescent (Tl) studies were carried out using a Tl 3500 hand held reader which yielded a brightness curve that ranged from room temperature to the 350 degrees Celsius. This BaHfO_3 response exhibits a broad brightness curve with a single peak centered around 225 degrees Celsius. Finally, is reported that there are materials of barium hafnate (BaHfO_3) doped with some rare earths (Eu, Tb) which, instead of improving the performance of the powders, decrease it, so that the use of intrinsic barium hafnate is the most appropriate.

    This paper reports NMR measurements of the magnetic dipole moments of two high-K isomers, the 37/2-, 51.4 m, 2740 keV state in Hf177 and the 8-, 5.5 h, 1142 keV state in Hf180 by the method of on-line nuclear orientation. Also included are results on the angular distributions of γ transitions in the decay of the Hf177 isotope. These yield high precision E2/M1 multipole mixing ratios for transitions in bands built on the 23/2+, 1.1 s, isomer at 1315 keV and on the 9/2+, 0.663 ns, isomer at 321 keV. The new results are discussed in the light of the recently reported finding of systematic dependence of the behavior of the gR parameter upon the quasiproton and quasineutron make up of high-K isomeric states in this region.

    The electric field gradients (EFG) of the Hf 2 Fe intermetallic compound were calculated using the full-potential linearized augmented plain-wave (FP-LAPW) method as embodied in the WIEN 97 code. The obtained values are compared with other ab-initio calculations and on a qualitative basis with the previously reported experimental data obtained from TDPAC. The calculated results, -23.1.10 21 V/m 2 and 2.7.10 21 V/m 2 for Hf 48f and Fe 32e position, respectively, are in excellent agreement with experimental data (23.4.10 21 V/m 2 and 2.7.10 21 V/m 2 ), better than those reported in earlier calculations. The calculated EFG for Hf 16c position (4.2.10 21 V/m 2 ) is stronger than the experimental one (1.1.10 21 V/m 2 ).

    Certain structural changes in the Naval Material Command which resulted from a comparison of its operations to those of selected large-scale private sector companies are described. Central to the change was a reduction in the number of formal reports from systems commands to headquarters, and the provision of Program Management Assistance Teams (at the request of the program manager) to help resolve project problems. It is believed that these changes improved communication and information-processing, reduced program manager stress, and resulted in improved productivity.

    Should North American Scientists and Science Societies continue with current communication programs or is there a need for expanded and or altered roles in Science Communication? If current practices are working, why is discourse outside of science societies so often misinformed and distorted on environmental change issues that are clearly defined and described within the science community? Climate change is one example there is virtual unanimity and overwhelming evidence from the scientific community that the Earth is warming rapidly and humans are an important cause, but there is confusion in the media and the public, in part due to disinformation campaigns by greenhouse gas polluters and privately funded "Think Tanks." A summary discussion will be presented that addresses many of the ideas and issues brought forward by colleagues in science, science communication and education. Scientists and Science Societies must re-establish objectivity in science information communication to educators, the media and the public. Recommendations on directions will be a key outcome of this presentation.
