    2014-01-01

    NASA's Space Communications and Navigation Testbed was installed on an external truss of the International Space Station in 2012. The testbed contains several software-defined radios (SDRs), including the Jet Propulsion Laboratory (JPL) SDR, which underwent performance testing throughout 2013 with NASAs Tracking and Data Relay Satellite System (TDRSS). On-orbit testing of the JPL SDR was conducted at S-band with the Glenn Goddard TDRSS waveform and compared against an extensive dataset collected on the ground prior to launch. This paper will focus on the development of a waveform power estimator on the ground post-launch and discuss the performance challenges associated with operating the power estimator in space.

    2015-01-01

    The Space Communications and Navigation (SCaN) Testbed project completed installation and checkout testing of a new S-Band ground station at the NASA Glenn Research Center in Cleveland, Ohio in 2015. As with all ground stations, a key alignment process must be conducted to obtain offset angles in azimuth (AZ) and elevation (EL). In telescopes with AZ-EL gimbals, this is normally done with a two-star alignment process, where telescope-based pointing vectors are derived from catalogued locations with the AZ-EL bias angles derived from the pointing vector difference. For an antenna, the process is complicated without an optical asset. For the present study, the solution was to utilize the gimbal control algorithms closed-loop tracking capability to acquire the peak received power signal automatically from two distinct NASA Tracking and Data Relay Satellite (TDRS) spacecraft, without a human making the pointing adjustments. Briefly, the TDRS satellite acts as a simulated optical source and the alignment process proceeds exactly the same way as a one-star alignment. The data reduction process, which will be discussed in the paper, results in two bias angles which are retained for future pointing determination. Finally, the paper compares the test results and provides lessons learned from the activity.

    The aim was to explore the major concerns of specialist nurses pertaining to academic learning during their education and initial professional career. Specialist nursing education changed in tandem with the European educational reform in 2007. At the same time, greater demands were made on the healthcare services to provide evidence-based and safe patient-care. These changes have influenced specialist nursing programmes and consequently the profession. Grounded Theory guided the study. Data were collected by means of a questionnaire with open-ended questions distributed at the end of specialist nursing programmes in 2009 and 2010. Five universities were included. Further, individual, pair and group interviews were used to collect data from 12 specialist nurses, 5-14 months after graduation. A major concern for specialist nurses was that academic learning should be "meaningful" for their professional future. The specialist nurses' "meaningful academic learning process" was characterised by an ambivalence of partly believing in and partly being hesitant about the significance of academic learning and partly receiving but also lacking support. Specialist nurses were influenced by factors in two areas: curriculum and healthcare context. They felt that the outcome of contribution to professional confidence was critical in making academic learning meaningful.

    A major concern of a university satellite mission is to download the payload and the telemetry data from a satellite. While the ground station antennas are in general easy and with limited afford to procure, the receiving unit is most certainly not. The flexible and low-cost software-defined radio (SDR) transceiver "BladeRF" is used to receive the QPSK modulated and CCSDS compliant coded data of a satellite in the HAM radio S-band. The control software is based on the Open Source program GNU Radio, which also is used to perform CCSDS post processing of the binary bit stream. The test results show a good performance of the receiving system.

    1994-08-01

    A geosynchronous satellite system capable of providing many channels of digital audio radio service (DARS) to mobile platforms within the contiguous United States using S-band radio frequencies is being implemented. The system is designed uniquely to mitigate both multipath fading and outages from physical blockage in the transmission path by use of satellite spatial diversity in combination with radio frequency and time diversity. The system also employs a satellite orbital geometry wherein all mobile platforms in the contiguous United States have elevation angles greater than 20 deg to both of the diversity satellites. Since implementation of the satellite system will require three years, an emulation has been performed using terrestrial facilities in order to allow evaluation of DARS capabilities in advance of satellite system operations. The major objective of the emulation was to prove the feasibility of broadcasting from satellites 30 channels of CD quality programming using S-band frequencies to an automobile equipped with a small disk antenna and to obtain quantitative performance data on S-band propagation in a satellite spatial diversity system.

    2011-01-10

    Communication between primary care physicians (PCPs) and specialists regarding referrals and consultations is often inadequate, with negative consequences for patients. We examined PCPs' and specialists' perceptions of communication regarding referrals and consultations. We then identified practice characteristics associated with reported communication. We analyzed the nationally representative 2008 Center for Studying Health System Change Health Tracking Physician Survey of 4720 physicians providing at least 20 hours per week of direct patient care. Outcome measures were physician reports of communication regarding referrals and consultations. Perceptions of communication regarding referrals and consultations differed. For example, 69.3% of PCPs reported "always" or "most of the time" sending notification of a patient's history and reason for consultation to specialists, but only 34.8% of specialists said they "always" or "most of the time" received such notification. Similarly, 80.6% of specialists said they "always" or "most of the time" send consultation results to the referring PCP, but only 62.2% of PCPs said they received such information. Physicians who did not receive timely communication regarding referrals and consultations were more likely to report that their ability to provide high-quality care was threatened. The 3 practice characteristics associated with PCPs and specialists reporting communication regarding referrals and consultations were "adequate" visit time with patients, receipt of quality reports regarding patients with chronic conditions, and nurse support for monitoring patients with chronic conditions. These modifiable practice supports associated with communication between PCPs and specialists can help inform the ways that resources are focused to improve care coordination.

    2012-08-28

    The S-Band loads on the current SLAC linac RF system were designed, in some cases, 40+ years ago to terminate 2-3 MW peak power into a thin layer of coated Kanthal material as the high power absorber [1]. The technology of the load design was based on a flame-sprayed Kanthal wire method onto a base material. During SLAC linac upgrades, the 24 MW peak klystrons were replaced by 5045 klystrons with 65+ MW peak output power. Additionally, SLED cavities were introduced and as a result, the peak power in the current RF setup has increased up to 240 MW peak. The problem of reliable RF peak power termination and RF load lifetime required a careful study and adequate solution. Results of our studies and three designs of S-Band RF load for the present SLAC RF linac system is discussed. These designs are based on the use of low conductivity materials.

  14. Suppression of Clutter Near Port by S-Band Radar

    Science.gov (United States)

    Ishii, Seishiro; Sayama, Syuji

    It was reported that various radar clutters obey a Weibull distribution under certain conditions. To suppress such Weibull-distributed clutter, a new adaptive method was proposed by the present authors. In this method, the parameters of the Weibull distribution and the threshold level for an adaptive Constant False Alarm Rate (CFAR) detector are determined by calculating the variance after it passed through a logarithmic amplifier. To apply this new method to practical problems observed by an S-band radar, computer simulation were made for a finite number of samples in order to obtain the CFAR maintenance in Weibull radar clutter which was including sea clutter and ground clutter from a variety of terrain near the port. Finally an improvement value of target-to-clutter ratio 49.5dB was obtained for the detection of ships embedded in sea clutter near the port.

    Various aspects of the shuttle orbiter S-band network communication system, the S-band payload communication system, and the Ku-band communication system are considered. A method is proposed for obtaining more accurate S-band antenna patterns of the actual shuttle orbiter vehicle during flight because the preliminary antenna patterns using mock-ups are not realistic that they do not include the effects of additional appendages such as wings and tail structures. The Ku-band communication system is discussed especially the TDRS antenna pointing accuracy with respect to the orbiter and the modifications required and resulting performance characteristics of the convolutionally encoded high data rate return link to maintain bit synchronizer lock on the ground. The TDRS user constraints on data bit clock jitter and data asymmetry on unbalanced QPSK with noisy phase references are included. The S-band payload communication system study is outlined including the advantages and experimental results of a peak regulator design built and evaluated by Axiomatrix for the bent-pipe link versus the existing RMS-type regulator. The nominal sweep rate for the deep-space transponder of 250 Hz/s, and effects of phase noise on the performance of a communication system are analyzed.

    We present an overview of the “KIFF” project, which provides ultra-deep K s -band imaging of all six of the Hubble Frontier Fields clusters, Abell 2744, MACS-0416, Abell S1063, Abell 370, MACS-0717, and MACS-1149. All of these fields have recently been observed with large allocations of Directors’ Discretionary Time with the Hubble and Spitzer telescopes, covering 0.4\\lt λ \\lt 1.6 μ {{m}} and 3.6-4.5 μ {{m}}, respectively. VLT/HAWK-I integrations of the first four fields reach 5σ limiting depths of {K}s˜ 26.0 (AB, point sources) and have excellent image quality (FWHM ˜ 0.″4). The MACS-0717 and MACS-1149 fields are observable from the northern hemisphere, and shorter Keck/MOSFIRE integrations on those fields reach limiting depths of K s = 25.5 and 25.1, with a seeing FWHM of ˜ 0.″4 and 0\\buildrel{\\prime\\prime}\\over{.} 5. In all cases the K s -band mosaics cover the primary cluster and parallel HST/ACS+WFC3 fields. The total area of the K s -band coverage is 490 arcmin2. The K s -band at 2.2 μ {{m}} crucially fills the gap between the reddest HST filter (1.6 μ {{m}} ˜ H band) and the IRAC 3.6 μ {{m}} passband. While reaching the full depths of the space-based imaging is not currently feasible from the ground, the deep K s -band images provide important constraints on both the redshifts and the stellar population properties of galaxies extending well below the characteristic stellar mass across most of the age of the universe, down to and including the redshifts of the targeted galaxy clusters (z≲ 0.5). Reduced, aligned mosaics of all six survey fields are provided.

    2016-07-01

    Full Text Available Radar backscatter from forest canopies is related to forest cover, canopy structure and aboveground biomass (AGB. The S-band frequency (3.1–3.3 GHz lies between the longer L-band (1–2 GHz and the shorter C-band (5–6 GHz and has been insufficiently studied for forest applications due to limited data availability. In anticipation of the British built NovaSAR-S satellite mission, this study evaluates the benefits of polarimetric S-band SAR for forest biophysical properties. To understand the scattering mechanisms in forest canopies at S-band the Michigan Microwave Canopy Scattering (MIMICS-I radiative transfer model was used. S-band backscatter was found to have high sensitivity to the forest canopy characteristics across all polarisations and incidence angles. This sensitivity originates from ground/trunk interaction as the dominant scattering mechanism related to broadleaved species for co-polarised mode and specific incidence angles. The study was carried out in the temperate mixed forest at Savernake Forest and Wytham Woods in southern England, where airborne S-band SAR imagery and field data are available from the recent AirSAR campaign. Field data from the test sites revealed wide ranges of forest parameters, including average canopy height (6–23 m, diameter at breast-height (7–42 cm, basal area (0.2–56 m2/ha, stem density (20–350 trees/ha and woody biomass density (31–520 t/ha. S-band backscatter-biomass relationships suggest increasing backscatter sensitivity to forest AGB with least error between 90.63 and 99.39 t/ha and coefficient of determination (r2 between 0.42 and 0.47 for the co-polarised channel at 0.25 ha resolution. The conclusion is that S-band SAR data such as from NovaSAR-S is suitable for monitoring forest aboveground biomass less than 100 t/ha at 25 m resolution in low to medium incidence angle range.

    The Space Shuttle STS-3 mission carried a Plasma Diagnostics Package (PDP) whose instrumentation included an S-band antenna and detector. The PDP was maneuvered by the Remote Manipulator System arm through a computer controlled sequence in the Orbiter's X-Z plane, above the quad and hemi S-band communications antennas. Antenna field strength measurements were conducted during transmitter high power modes, and the results were compared to ground full scale measurements and predictions. A field strength 4.8 + or - 3 dB higher than predicted is noted. This RF field is primarily due to the quad PM transmitter, whose power output of 115 W compares with 15 W for the hemi.

    The development of adequate modulators for high peak power klystrons is one of the focus points for linear collider R&D programs. For the DESY/THD S-band linear collider study 150 MW rf-pulse power at 50 Hz repetition rate and 3 μs pulse duration is required [1]. Two different modulator schemes are under investigation. One is the conventional line type pulser, using a pulse forming network and a step up transformer, the other one is a hard tube pulser, using a dc power source at the full klystron voltage and a switch tube. This paper is focused on the modulator development for the S-band Test Linac at DESY. After a short overview over the test linac and a brief description of the 150 MW S-band klystron the circuitry of the line type pulse (LTP) is given. A hard tube pulser (HTP), which switches the high voltage directly from a storage capacitor to the klystron, has been built up at DESY. Circuitry and the results of the commissioning of the switch tube are reported.

    Modeling carried out demonstrates possibility of generation of gigawatt power level S band microwave pulse with duration of several nanoseconds using superradiation of short electron beam moving along slow-wave periodical structure. A 10 ns / 500 keV / 5 kA accelerator of Kanazawa University can be used in such experiments. It is shown that significant increasing peak power can be obtained by optimization of voltage and current pulses waveforms. Required increasing of electron energy and current by the end of electron pulse can be achieved by using self-acceleration of a short beam passing through a system of passive cavities. (author)

  5. Ranging and target detection performance through lossy media using an ultrawideband S-band through-wall sensing noise radar

    Smith, Sonny; Narayanan, Ram M.

    2013-05-01

    An S-band noise radar has been developed for through-wall ranging and tracking of targets. Ranging to target is achieved by the cross-correlation between the time-delayed reflected return signal and the replica of the transmit signal; both are bandlimited ultrawideband (UWB) noise signals. Furthermore, successive scene subtraction allows for target tracking using the range profiles created by the cross-correlation technique. In this paper, we explore the performance of the radar system for target detection through varied, lossy media (e.g. a 4-inch thick brick wall and an 8-inch thick cinder-block wall) via correlation measurements using the S-band radar system. Moreover, we present a qualitative analysis of the S-band noise radar as operated under disparate testing configurations (i.e. different walls, targets, and distances.) with different antennas (e.g. dual polarized horns, helical antennas with different ground planes, etc.). In addition, we discuss key concepts of the noise radar design, considerations for an antenna choice, as well as experimental results for a few scenarios.

    The isolation between the upper S-band quad antenna and the S-band payload antenna on the shuttle orbiter is calculated using a combination of plane surface and curved surface theories along with worst case values. A minimum value of 60 db isolation is predicted based on recent antenna pattern data, antenna locations on the orbiter, curvature effects, dielectric covering effects and edge effects of the payload bay. The calculated value of 60 db is significantly greater than the baseline value of 40 db. Use of the new value will result in the design of smaller, lighter weight and less expensive filters for S-band transponder and the S-band payload interrogator.

    A gain-flattened S-band erbium-doped fiber amplifier (EDFA) using standard erbium-doped fiber (EDF) is proposed and experimentally demonstrated. The proposed amplifier with two-stage double-pass configuration employs two C-band suppressing filters to obtain the optical gain in S-band. The amplifier provides a maximum signal gain of 41.6 dB at 1524 nm with the corresponding noise figure of 3.8 dB. Furthermore, with a well-designed short-pass filter as a gain flattening filter (GFF), we are able to develop the S-band EDFA with a flattened gain of more than 20 dB in 1504-1524 nm. In the experiment, the two-stage double-pass amplifier configuration improves performance of gain and noise figure compared with the configuration of single-stage double-pass S-band EDFA.

    provide single, dual, compact and quasi-quad polarization imaging modes. Centre frequency for S-band SAR is 3200MHz with highest bandwidth of 75MHz. S-Band SAR utilizes 24 transmit receive modules (T/R Modules) to illuminate >240kms swath during transmit event and digital beam forming (DBF) on receive to reduce data rate by combining 24 receive channels and enhance SNR of the system. This paper provides details of S-band SAR system design, configuration and realization which is a challenging task since both L-band and S-band radars need to operate at same PRF and clock reference during simultaneous imaging operation. Further to this, SweepSAR technique demands PRF dithering (changing) to avoid dead gaps in the swath due to receive echo conflicting with transmit event.

    Full Text Available Assessments of forest cover, forest carbon stocks and carbon emissions from deforestation and degradation are increasingly important components of sustainable resource management, for combating biodiversity loss and in climate mitigation policies. Satellite remote sensing provides the only means for mapping global forest cover regularly. However, forest classification with optical data is limited by its insensitivity to three-dimensional canopy structure and cloud cover obscuring many forest regions. Synthetic Aperture Radar (SAR sensors are increasingly being used to mitigate these problems, mainly in the L-, C- and X-band domains of the electromagnetic spectrum. S-band has not been systematically studied for this purpose. In anticipation of the British built NovaSAR-S satellite mission, this study evaluates the benefits of polarimetric S-band SAR for forest characterisation. The Michigan Microwave Canopy Scattering (MIMICS-I radiative transfer model is utilised to understand the scattering mechanisms in forest canopies at S-band. The MIMICS-I model reveals strong S-band backscatter sensitivity to the forest canopy in comparison to soil characteristics across all polarisations and incidence angles. Airborne S-band SAR imagery over the temperate mixed forest of Savernake Forest in southern England is analysed for its information content. Based on the modelling results, S-band HH- and VV-polarisation radar backscatter and the Radar Forest Degradation Index (RFDI are used in a forest/non-forest Maximum Likelihood classification at a spatial resolution of 6 m (70% overall accuracy, κ = 0.41 and 20 m (63% overall accuracy, κ = 0.27. The conclusion is that S-band SAR such as from NovaSAR-S is likely to be suitable for monitoring forest cover and its changes.

    Specialist bibliographic databases offer essential online tools for researchers and authors who work on specific subjects and perform comprehensive and systematic syntheses of evidence. This article presents examples of the established specialist databases, which may be of interest to those engaged in multidisciplinary science communication. Access to most specialist databases is through subscription schemes and membership in professional associations. Several aggregators of information and database vendors, such as EBSCOhost and ProQuest, facilitate advanced searches supported by specialist keyword thesauri. Searches of items through specialist databases are complementary to those through multidisciplinary research platforms, such as PubMed, Web of Science, and Google Scholar. Familiarizing with the functional characteristics of biomedical and nonbiomedical bibliographic search tools is mandatory for researchers, authors, editors, and publishers. The database users are offered updates of the indexed journal lists, abstracts, author profiles, and links to other metadata. Editors and publishers may find particularly useful source selection criteria and apply for coverage of their peer-reviewed journals and grey literature sources. These criteria are aimed at accepting relevant sources with established editorial policies and quality controls.

    2009-10-01

    K+-Na+ ion-exchanged channel waveguide amplifiers have been fabricated in Tm3+-doped acid-resistant aluminum germanate glasses. The optical and relative gains of a 3.15-cm-long waveguide channel were achieved to be 4.05 and 2.29 dB at 1.482 μm wavelength under 110 mW 793 nm laser excitation, respectively. After compensating the propagation loss, an internal gain of 1.50 dB and a remarkable gain coefficient of 0.48 dB/cm were obtained, which reveals a definite S-band signal amplification in the low phonon energy glass waveguide. As an expectation, UV-radiation-sensitive glass waveguide should promote the developments of gain-flatten S-band waveguide amplifiers, infrared UV-writing grating waveguide lasers, and compact multifunctional integrated optical devices.

    New short-wavelength SASE light sources will require very bright electron beams, brighter in some cases than is now possible. One method for improving brightness involves the careful shaping of the electron bunch to control the degrading effects of its space charge forces. We study this experimentally in an S-band system, by using an acousto-optical programmable dispersive filter to shape the photocathode laser pulse that drives the RF photoinjector. We report on the efficacy of shaping from the IR through the UV, and the effects of shaping on the electron beam dynamics.

    Damping cells for the higher order modes are necessary for the S-band linear collider to minimize BBU (Beam-Break-Up). The construction of the damper cells has to take into account the different field geometries of the higher order modes. So two different types of dampers have been designed: a wall slotted an an iris slotted cell. In order to optimize the two types of damping cells with respect to damping strength, impedance matching between coupling system and waveguide dampers and between d...

    @@ We have synchronized a 102-MHz ultrafast self-mode-locked Ti:sapphire laser to a 2856-MHz rf source with the sample-locking technology. The relative root-mean-square time-jitter is 0.57ps and the maximum time jitter is 2.60ps. This is the first time that synchronization between the ultrafast laser pulse and the s-band microwave has been accomplished in China. Potential applications include synchronization of lasers and rf power sources in particle accelerator experiments and high-resolution pump-probe experiments.

    Mental health peer specialists are individuals with serious mental illnesses who receive training to use their lived experiences to help others with serious mental illnesses in clinical settings. This Open Forum discusses the state of the research for mental health peer specialists and suggests a research agenda to advance the field. Studies have suggested that peer specialists vary widely in their roles, settings, and theoretical orientations. Theories of action have been proposed, but none have been tested. Outcome studies have shown benefits of peer specialists; however, many studies have methodological shortcomings. Qualitative descriptions of peer specialists are plentiful but lack grounding in implementation science frameworks. A research agenda advancing the field could include empirically testing theoretical mechanisms of peer specialists, developing a measure of peer specialist fidelity, conducting more rigorous outcomes studies, involving peer specialists in executing the research, and assessing various factors that influence implementing peer specialist services and testing strategies that could address those factors.

    The original ALHAMBRA catalogue contained over 400,000 galaxies selected using a synthetic F814W image, to the magnitude limit AB(F814W)$\\approx$24.5. Given the photometric redshift depth of the ALHAMBRA multiband data (=0.86) and the approximately $I$-band selection, there is a noticeable bias against red objects at moderate redshift. We avoid this bias by creating a new catalogue selected in the $K_s$ band. This newly obtained catalogue is certainly shallower in terms of apparent magnitude, but deeper in terms of redshift, with a significant population of red objects at $z>1$. We select objects using the $K_s$ band images, which reach an approximate AB magnitude limit $K_s \\approx 22$. We generate masks and derive completeness functions to characterize the sample. We have tested the quality of the photometry and photometric redshifts using both internal and external checks. Our final catalogue includes $\\approx 95,000$ sources down to $K_s \\approx 22$, with a significant tail towards high redshift. We have ...

    Measurement of the bunch structure of a pico-second single bunch was performed using a femto-second streak camera at the S-band linear accelerator of the University of Tokyo. The aim of this research is to investigate the feasibility of the generation of a femto-second single bunch at the S-band linac. The details of the bunch structure and energy spectrum of an original single bunch were precisely investigated in several operation modes where the RF phases in accelerating tubes and a prebuncher were varied. The femto-second streak camera was utilized to measure the bunch structure by one shot via Cherenkov radiation emitted by the electrons in the bunch. Next, an experiment for magnetic pulse compression of the original single bunch was carried out. Pulse shapes of the compressed bunchs for different energy modulation were also obtained by measuring Cherenkov radiation by one shot using the femto-second streak camera. Prior to the experiment, numerical tracking analysis to determine operating parameters for the magnetic pulse compression was also done. Measured pulse widths were compared with calculated ones. Finally, a 2 ps (full width at half maximum; FWHM) single bunch with an electric charge of 0.3 nC could be generated by the magnetic pulse compression. ((orig.))

    A passively Q-switched S-band fiber laser using Molybdenum Diselenide (MoSe2) saturable absorber (SA) is proposed and demonstrated. The SA is fabricated by depositing MoSe2 onto two fiber ferrules using the drop-cast method before heating and connecting the two fiber ferrules to form the SA. The passively Q-switched fiber laser designed using the MoSe2 SA has an operational range of 1491.0-1502.0 nm. The output pulse train has a pulse-width ranging from 2.0 μs to 1.0 μs and corresponding repetition rate of between 34.5 kHz and 90 kHz with increasing pump powers, as well as a signal-to-noise of about 35.97 dB. The peak performance of the proposed laser is between 1480.0 and 1490.0 nm, corresponding to the first peak gain region with the S-band.

    The Assembly and Contingency Radio Frequency Group (ACRFG) onboard the International Space Station (ISS) is used for command and control communications and transmits (45 dBm or 32 watts) and receives at S-band. The system is nominally pressurized with gaseous helium (He) and nitrogen (N2) at 8 pounds per square inch absolute (psia). MacDonald, Dettwiler and Associates Ltd. (MDA) was engaged to analyze the operational characteristics of this unit in an effort to determine if the anomalous behavior was a result of a corona event. Based on this analysis, MDA did not recommend continued use of this ACRFG. The NESC was requested to provide expert support in the area of high-voltage corona and multipactoring in an S-Band RF system and to assess the probability of corona occurring in the ACRFG during the planned EVA. The NESC recommended minimal continued use of S/N 002 ACRFG until a replacement unit can be installed. Following replacement, S/N 002 will be subjected to destructive failure analysis in an effort to determine the proximate and root cause(s) of the anomalous behavior.

    2005-01-01

    @@ An efficient and low noise short wavelength band erbium-doped fibre amplifier (S-band EDFA) is proposed and demonstrated using double-pass configuration. This amplifier provides a gain of 1500 nm signal as high as 26.9 dB,which is 9.6 dB higher than the two-stage single-pass amplifier. The corresponding noise figure obtained is 7.5 dB,which is of the same level as in the single-pass amplifier and more than 2dB lower than the previously reported double-pass amplifier [IEICE Electron. Express 2 (2005) 182]. The gain enhancement is due to the double pass-propagation of the test signal in the second stage, which increases the effective erbium-doped fibre (EDF)length. The low noise is attributed to the optical circulator between EDFs, which prevents the backward amplified spontaneous emission from propagating into the input part of the amplifier. The proposed amplifier is expected to play an important role in the development of a practical S-band EDFA.

    This study presents a comprehensive comparison of radar altimetry signatures at Ka-, Ku-, C-, and S-bands using SARAL, ENVISAT and Jason-2 data over the major bioclimatic zones, soil and vegetation types encountered in West-Africa, with an emphasis on the new information at Ka-band provided by the recently launched SARAL-Altika mission. Spatio-temporal variations of the radar altimetry responses were related to changes in surface roughness, land cover and soil wetness. Analysis of time series of backscattering coefficients along the West African bioclimatic gradient shows that radar echoes at nadir incidence are well correlated to soil moisture in semi-arid savannah environments. Radar altimeters are able to detect the presence of water even under a dense canopy cover at all frequencies. But only measurements at Ka-band are able to penetrate underneath the canopy of non-inundated tropical evergreen forests.

    The activities with the compact X-ray source are attracting more attention, particularly for the applications of the source in medical fields. We propose the fabrication of a compact X-ray source using the SAMEER electron linear accelerator and the KEK laser undulator X-ray source (LUCX) technologies. The linac developed at SAMEER is a standing wave side-coupled S-band linac operating in the {pi}/2 mode. In the proposed system, a photocathode RF gun will inject bunches of electrons in the linac to accelerate and achieve a high-energy, low-emittance beam. This beam will then interact with the laser in the laser cavity to produce X-rays of a type well suited for various applications. The side-coupled structure will make the system more compact, and the {pi}/2 mode of operation will enable a high repetition rate operation, which will help to increase the X-ray yield.

    1986-12-01

    An intersite tracking campaign was organized, with 4 S-band stations, for a period of 1 wk to show how the most precise orbit can be computed with the operational software. This precise orbit served as a reference in order to evaluate what can be achieved with one single station with range and angular measurements (a typical configuration used for stationkeeping of geostationary satellites). Orbit computation implied numerical integration with gravitational (Earth, Moon, and Sun) and solar radiation pressure as forces acting on the satellite. Arc lengths of 2 days gave initial state vectors which were compared every day. A precision of 10 m is achieved. However, an analysis of the influence of several parameters entering the orbit computations reveals that the absolute accuracy is of the order of 100 m, since modeling perturbations were neglected in the operational software (polar motion for example). This reference orbit allows estimation of systematic errors for other tracking antennas.

    2011-01-01

    An S-band cavity BPM is designed for a new injector in National Synchrotron Radiation Laboratory. A re-entrant position cavity is tuned to the TM110 mode as position cavity. Cut-through waveguides are used as pickups to suppress the monopole signal. Theoretical resolution of this design is 31 nm. A prototype cavity BPM system is manufactured for off-line cold tests. The wire scanning method is used to calibrate the BPM and estimate the performance of the on-line BPM system. A cross-talk problem has been detected during the cold test. Racetrack cavity BPM design can be used to suppress the cross-talk. With the nonlinear effect being ignored, transform matrix can be used to correct cross-talk. Analysis of cold test results shows that the position resolution of prototype BPM is better than 3 μm.

    2014-09-01

    As an electron beam injector of X-ray free-electron lasers (FELs), photoinjectors have been developed for the past few decades. Such an injector starting with a photocathode RF gun provides high brightness beams and therefore it is being adopted as an injector of X-ray FELs. In this paper we show how to improve photoinjector performance in terms of emittance and repetition rates by means of injector components optimization, especially with the gun. Transverse emittance at the end of an injector is reduced by optimizing the gun design, gun solenoid position, and accelerating section position. The repetition rate of an injector mainly depends on the gun. It is discussed that a repetition rate of 1 kHz at a normal-conducting S-band photoinjector is feasible by adopting a coaxial RF coupler and improving cooling-water channels surrounding the gun.

    The S-band radars of the Meteorological Research Institute (IPMet) in Bauru and Presidente Prudente are situated within major sugar cane producing regions in the State of São Paulo, where the sugar cane is harvested from April until November, generally by burning sectors of the plantations prior to manual harvesting, resulting in large quantities of aerosols being emitted into the atmosphere, not only negatively affecting local towns, but also regions much further away. In the absence of rain during the dry winter season, the actual fires and subsequent plumes can be observed by IPMet's S-band Doppler radars within their 240 km quantitative ranges, deploying a special scanning cycle which was configured to provide a better vertical resolution up to the anticipated detectable top of the plumes (10 elevations from 10,0° down to 0,3°; resolution of 250 m in range and 1° in azimuth; 7,5 min per volume scan). During August 2010, a one-month multi-disciplinary pilot study was executed with two-fold objectives in two separate regions of the Bauru radar range: to verify the onset of the actual fire and quantify the combustion process and to characterize the effects of those emissions on the atmosphere. The TITAN (Thunderstorm Identification, Tracking, Analysis and Nowcasting) Software was deployed to determine the intensity of the initial fire (based on radar reflectivity in dBZ), and subsequently the horizontal and vertical dimensions of the smoke plume and the velocity of dispersion. The thresholds used for tracking the smoke envelopes were 10 dBZ with a minimum volume of 2 km3, but the position and extent of already diluted plumes could be identified up to 100-150 km range at -6 dBZ. Samples of the biomass material were collected to characterize and quantify the fuel mass before and after burning, which could be related to the fire intensity and subsequent aerosol density of the smoke plume (experimental site ca 50 km east of Bauru).

    This study aims to explain the development of S-band photocathode RF guns at Tsinghua University, with especial attention on the progress of guns developed after 2011. Two types of RF guns were developed based on the BNL/SLAC/UCLA gun prior 2011. These guns have been operated as electron sources for Tsinghua Thomson scattering X-ray source (TTX), MeV ultrafast electron diffraction, and Shanghai deep ultraviolet FEL test facility. Based on our operation experiences and other gun modifications worldwide, numerous improvements have been proposed, and seven third-type guns have been designed and fabricated since 2011. Cold tests of all third-type guns have been completed, confirming a significantly improved quality factor and mode separation. The first third-type gun has been installed on TTX and operated for four years, demonstrating high gradient, low dark current, stable quantum efficiency, and small emittances. The optimal transverse emittance was εx = 0.56 mm mrad , εy = 0.66 mm mrad for 200 pC with a peak current of 25 A, and εx = 0.78 mm mrad , εy = 0.92 mm mrad for 500 pC with a peak current of 62.5 A under a 110 MV/m gun gradient.

The relative geometry of the network with respect to the satellites was an opportunity to show how the most precise orbit can be computed with the operational software. This precise orbit served as a reference to evaluate what can be achieved with one station with range and angular measurements, a typical configuration used for stationkeeping of geostationary satellites. Orbit computation implied numerical integration with gravitational (Earth, Moon, and Sun) and solar radiation pressure forces acting on the satellite. Arc lengths of 2 days gave initial state vectors which were compared every day. Precision of 10 m is achieved. However, an analysis of the influence of parameters in the orbit computations reveals that the absolute accuracy is of the order of 100 m, since modeling perturbations were neglected in the operational software (e.g., polar motion). In a relative sense, the reference orbit allows estimation of systematic errors for other tracking antennas.

    A deep K_s-band photometric catalogue of galaxies at the core of the rich, nearby Norma cluster (ACO3627) is presented. The survey covers about 45 by 45 square arcmin (slightly less than 1/3 Abell radius), which corresponds to approx. 0.8 Mpc^2 at the adopted distance (v_cmb/H0) of 70 Mpc of this cluster. The survey is estimated to be complete to a magnitude of M_Ks <~ -19.5 mag. This extends into the dwarf regime, 6 magnitudes below M_Ks*. The catalogue contains 390 objects, 235 of which are classified as likely or definite galaxies and 155 as candidate galaxies. The Ks-band luminosity function (LF) is constructed from the photometric sample, using a spectroscopic subsample to correct for fore- and background contamination. We fit a Schechter function with a characteristic magnitude of M_Ks* = -25.39 \\pm 0.80 mag and faint-end slope of alpha = -1.26 \\pm 0.10 to the data. The shape of the LF is similar to those found in previous determinations of the cluster LF, in both optical and near infrared. The Schec...

    Photocathode RF guns have been developed in many laboratories for generating high quality electron beams for free-electron lasers based on linear accelerators. Such guns can generate electron beams with an exceptionally high peak current as well as a small transverse emittance. Their applications have been recently expanded for ultrafast electron diffraction, coherent terahertz radiation, and X-ray or γ-ray radiation by Compton scattering. In this paper, we design an S-band normal-conducting gun with capabilities of high quality beam generation and high repetition rate operation. The RF design and thermal analysis of the gun cavity and coupler are introduced. Optimal position of the gun focusing solenoid for low emittance beam generation is found by performing particle tracking simulations. Then, the gun system is designed to be able to afford the optimal solenoid position. The cooling-water channel surrounding the gun cavity and coupler is designed and analyzed numerically. The pressure in the gun is simulated with a vacuum model containing the detailed inner structure of the gun. An injector for a free-electron laser application is designed by using this gun and the beam dynamics simulation is shown. A cold test with a prototype gun for confirmation of the RF design is reported.

    A Q-switched S-band thulium fluoride fiber (TFF) driven by a 1400 nm laser diode is proposed and demonstrated. The TFF has the advantage of being pumped at 1400 nm, which is an easily available and relatively low-cost pump source, as opposed to conventional pumping at 1050 nm. It has a gain profile from 1440 nm to 1520 nm, and Q-switching is realized with the use of a thin film graphene saturable absorber. The Q-switched TFF laser exhibits a maximum repetition rate and minimum pulse width of 36.3 kHz and 3.2 µs respectively, as well as an average output power and pulse energy of 0.76 mW and 20.9 nJ at a maximum pump power of 230.4 mW. The output pulses are highly stable, and to the best knowledge of the authors this is the first demonstration of a Q-switched TFF laser pumped at 1400 nm.

    The inflatable antenna for CubeSat is a 1 meter antenna reflector designed with one side reflective Mylar, another side clear Mylar with a patch antenna at the focus. The development of this technology responds to the increasing need for more capable communication systems to allow CubeSats to operate autonomously in interplanetary missions. An initial version of the antenna for the S-Band was developed and tested in both anechoic chamber and vacuum chamber. Recent developments in transceivers and amplifiers for CubeSat at X-band motivated the extension from the S-Band to the X-Band. This paper describes the process of extending the design of the antenna to the X-Band focusing on patch antenna redesign, new manufacturing challenges and initial results of experimental tests.

  11. On the origin of the ionosphere at Moon : a study using results from Chandrayaan-I S-band radio occultation experiment and a photochemical model

    2016-07-01

    Using Chandrayaan-1 communication link between orbiter and ground (S-band frequency), the presence of ionosphere at Moon has been explored using Radio Occultation technique. Results obtained from the observations conducted between July 30 and August 14, 2009 show evidence for a possible existence of the Ionosphere at Moon. A few seconds before the occultation of Chandrayaan-1 radio signals, extra fluctuation in the rate of change of difference between the theoretically estimated Doppler and observed Doppler was observed. The fluctuation was more pronounced when the probing radio waves were crossing through the day-night terminator. Using standard onion-peeling technique to invert the phase changes in radio signals to the refractivity of the medium, we estimated the bending angle and hence the electron density profiles for the Lunar medium. The estimated electron density near the Lunar surface was of the order of 400 - 1000 cm ^{-3} which decreased monotonically with increasing altitude till about 40 km above the surface where it became negligible. The observed electron density was compared with the results from a model which was developed based on CHACE measurements abroad Moon Impact Probe of Chandrayaan-I. The model included the photo chemical reactions and solar wind interactions of the lunar plasma. We propose that the ionosphere over Moon could have molecular origin with H _{2}O ^{+},CO_{2} ^{+} and H_{3}O ^{+} as dominant ions.

  14. Development of new S-band RF window for stable high-power operation in linear accelerator RF system

    2017-09-01

    For stable high-power operation, a new RF window is developed in the S-band linear accelerator (Linac) RF systems of the Pohang Light Source-II (PLS-II) and the Pohang Accelerator Laboratory X-ray Free-Electron Laser (PAL-XFEL). The new RF window is designed to mitigate the strength of the electric field at the ceramic disk and also at the waveguide-cavity coupling structure of the conventional RF window. By replacing the pill-box type cavity in the conventional RF window with an overmoded cavity, the electric field component perpendicular to the ceramic disk that caused most of the multipacting breakdowns in the ceramic disk was reduced by an order of magnitude. The reduced electric field at the ceramic disk eliminated the Ti-N coating process on the ceramic surface in the fabrication procedure of the new RF window, preventing the incomplete coating from spoiling the RF transmission and lowering the fabrication cost. The overmoded cavity was coupled with input and output waveguides through dual side-wall coupling irises to reduce the electric field strength at the waveguide-cavity coupling structure and the possibility of mode competitions in the overmoded cavity. A prototype of the new RF window was fabricated and fully tested with the Klystron peak input power, pulse duration and pulse repetition rate of 75 MW, 4.5 μs and 10 Hz, respectively, at the high-power test stand. The first mass-produced new RF window installed in the PLS-II Linac is running in normal operation mode. No fault is reported to date. Plans are being made to install the new RF window to all S-band accelerator RF modules of the PLS-II and PAL-XFEL Linacs. This new RF window may be applied to the output windows of S-band power sources like Klystron as wells as the waveguide windows of accelerator facilities which operate in S-band.

    While there is no proven cure for lipoedema, early detection is key as specialist treatments, complemented by self-management techniques, can improve symptoms and prevent progression. There is no universal approach as the correct treatment or treatments will depend on each patient's particular circumstances; however, when chosen early and appropriately, interventions can provide huge benefits. The most common treatments in the management of lipoedema include compression, manual lymphatic drainage (MLD), tumescent liposuction, intermittent pneumatic compression therapy (IPC), kinesio taping, deep oscillation therapy, and cognitive behavioural therapy (CBT).

    In this Letter, the authors fabricate for the first time MEMS fractal capacitors possessing two layers and compare their performance characteristics with the conventional parallel-plate capacitor and previously reported state-of-the-art single-layer MEMS fractal capacitors. Explicitly, a capacitor with a woven structure and another with an interleaved configuration were fabricated in the standard PolyMUMPS surface micromachining process and tested at S-band frequencies. The self-resonant frequencies of the fabricated capacitors were close to 10GHz, which is better than that of the parallel-plate capacitor, which measured only 5.5GHz. Further, the presented capacitors provided a higher capacitance when compared with the state-of-the-art-reported MEMS fractal capacitors created using a single layer at the expense of a lower quality factor. © 2012 The Institution of Engineering and Technology.

    We describe the geometry, architecture, dark- and optical performance of ultra-low-noise transition edge sensors as THz detectors for the SAFARI instrument. The TESs are fabricated from superconducting Mo/Au bilayers coupled to impedance-matched superconducting β-phase Ta thin-film absorbers. The detectors have phonon-limited dark noise equivalent powers of order 0.5 - 1.0 aW/ √ Hz and saturation powers of order 20 - 40 fW. The low temperature test configuration incorporating micro-machined backshorts is also described, and construction and typical performance characteristics for the optical load are shown. We report preliminary measurements of the optical performance of these TESs for two SAFARI bands; L-band at 110 - 210 μm and S-band 34 - 60 μm .

    A nonzero intermediate frequency (IF) likelihood acquisition scheme designed for S-band Single Access (SSA) link of China's Tracking and Data Relay Satellite S y stem (CTDRSS) is introduced. The received signal is downconv erted to IF, and then direct sampled in IF using a 1-bit A/D. After the digital i zation, the sampled data is detected using a hybrid likelihood acquisition schem e. Using this structure, large noise figure of the analog mixer or active filter s, amplitude and phase imbalance between low-frequency in-phase and quandratur e- phase channel can be avoided. An easy designing algorithm of the acquisition sch eme is also derived. The performance and algorithm are verified by computer simu lation.

    Science.gov (United States)

    Stevens, S; Moors, M

    2013-01-01

    Independent medical specialists in the Netherlands are treated as entrepreneurs for tax purposes and therefore enjoy tax benefits. A change in the legal relationship between medical specialists and hospitals is foreseen in 2015. Independent medical specialists will then no longer be considered to be entrepreneurs. This could negatively affect their tax position. The Dutch government has adopted a policy aimed at controlling expenses arising from medical specialists' fees. According to this policy, the formation of regional practices or mega-practices of specialists will be discouraged. In contrast, the current fiscal legislation encourages medical specialists to incorporate their practice into regional practices or mega-practices or to become shareholders of their hospitals. It has been proposed that fiscal benefits be linked to certain aspects of entrepreneurship, such as investing in medical equipment or employing medical personnel.

    2012-01-01

    Ergonomics is a holistic discipline encompassing a wide range of special interest groups. The role of an ergonomics consultant is to provide integrated solutions to improve comfort, safety and productivity. In Australia, there are two types of consultants--generalists and specialists. Both have training in ergonomics but specialist knowledge may be the result of previous education or work experience. This paper presents three projects illustrating generalist and specialist (visual ergonomics) consultancy: development of a vision screening protocol, solving visual discomfort in an office environment and solving postural discomfort in heavy industry. These case studies demonstrate how multiple ergonomics consultants may work together to solve ergonomics problems. It also describes some of the challenges for consultants, for those engaging their services and for the ergonomics profession, e.g. recognizing the boundaries of expertise, sharing information with business competitors, the costs-benefits of engaging multiple consultants and the risk of fragmentation of ergonomics knowledge and solutions. Since ergonomics problems are often multifaceted, ergonomics consultants should have a solid grounding in all domains of ergonomics, even if they ultimately only practice in one specialty or domain. This will benefit the profession and ensure that ergonomics remains a holistic discipline.

  5. A High-Resolution S-band Down-Converting Digital Phase Detector for SASE FEL Use

    CERN Document Server

    2004-01-01

    Each of the rf phase detectors in the Advanced Photon Source linac consists of a module that down converts from S-band to 20 MHz followed by an analog I/Q detector. Phase is calculated from one digitized sample per pulse each of I and Q. The resulting data has excellent long-term stability but is noisy enough so that a number of samples must be averaged to get a usable reading. The more recent requirement to support a SASE FEL has presented the need to accurately resolve the relative phase of a single pulse. Replacing analog detection with digital sampling and replacing internal intermediate frequency reference oscillators with a lower noise external oscillator were used to control the two largest components of noise. The implementation of a central, ultralow noise reference oscillator and a distribution system capable of maintaining the low phase noise is described, together with the results obtained to date. The principal remaining technical issue is determining the processing power required as a function o...

  9. A feasibility study of high intensity positron sources for the S-band and TESLA linear colliders

    Energy Technology Data Exchange (ETDEWEB)

    Glantz, R.

    1997-10-01

    Future high energy linear colliders require luminosities above 10{sup 33} cm{sup -2}s{sup -1}. Therefore beam intensities have to be provided up to two orders of magnitude higher than achieved at present. It is comparably simple to reach high electron intensities. Positron intensities in this range, however, are difficult to realize with conventional positron sources. A new method of positron production was proposed in 1979 by V.E. Balakin and A.A. Mikhailichenko. The photons, necessary for pair production, are not generated by bremsstrahlung but by high energy electrons passing through an undulator. Based on this principle, a high intensity, unpolarized and polarized positron source for linear colliders was developed by K.Floettmann. In the present work, the requirements derived by K.Floettmann are used to study the feasibility of both the polarized and the unpolarized positron source. For economical reasons it is advantageous to use the beam after the interaction for positron production. In the main part of the present work a beam line is developed which guarantees a stable operation of the unpolarized wiggler-based positron source for the S-Band and TESLA linear collider. The requirements on the electron beam emittances are much higher for the polarized undulator-based source. For TESLA it is shown, that an operation of the polarized source is possible for design interactions. For a stable operation, taking into account perturbations at the interaction point, further investigations are necessary. For the SBLC, an operation of the polarized source is not possible with the present design.

    LRO has been in a polar lunar orbit for 7 year since it was launched in June 2009. Seven instruments are onboard LRO to perform a global and detailed geophysical, geological and geochemical mapping of the Moon, some of which have very high spatial resolution. To take full advantage of the high resolution LRO datasets from these instruments, the spacecraft orbit must be reconstructed precisely. The baseline LRO tracking was the NASA's White Sands station in New Mexico and a commercial network, the Universal Space Network (USN), providing up to 20 hours per day of almost continuous S-band radio frequency link to LRO. The USN stations produce S-band range data with a 0.4 m precision and Doppler data with a 0.8 mm/s precision. Using the S-band tracking data together with the high-resolution gravity field model from the GRAIL mission, definitive LRO orbit solutions are obtained with an accuracy of 10 m in total position and 0.5 m radially. Confirmed by the 0.50-m high-resolution NAC images from the LROC team, these orbits well represent the LRO orbit "truth". In addition to the S-band data, one-way Laser Ranging (LR) to LRO provides a unique LRO optical tracking dataset over 5 years, from June 2009 to September 2014. Ten international satellite laser ranging stations contributed over 4000 hours LR data with the 0.05 - 0.10 m normal point precision. Another set of high precision LRO tracking data is provided by the Deep Space Network (DSN), which produces radiometric tracking data more precise than the USN S-band data. In the last two years of the LRO mission, the temporal coverage of the USN data has decreased significantly. We show that LR and DSN data can be a good supplement to the baseline tracking data for the orbit reconstruction.

    Adequate nutritional support includes many different aspects, but poor understanding of clinical nutrition by health care professionales often results in an inadequate prescription. A study was conducted to compare enteral and parenteral nutritional support plans prescribed by specialist and non-specialist physicians. Non-specialist physicians recorded anthropometric data from only 13.3% of patients, and none of them performed nutritional assessments. Protein amounts provided by non-specialist physicians were lower than estimated based on ESPEN (10.29g of nitrogen vs 14.62; P<.001). Differences were not statistically significant in the specialist group (14.88g of nitrogen; P=.072). Calorie and glutamine provision and laboratory controls prescribed by specialists were significantly closer to those recommended by clinical guidelines. Nutritional support prescribed by specialists in endocrinology and nutrition at San Pedro de Alcántara Hospital was closer to clinical practice guideline standards and of higher quality as compared to that prescribed by non-specialists.

    Koerner, M. A.

    1984-01-01

    A new DSN RF system is being developed that transmits at X-band and receive at both X-band and S-band. End-to-end tests are planned to measure the phase stability of this system. Equations for the phase transfer functions between the error sources in the system and the X-band and S-band Doppler extractor outputs are derived. This analysis considers both test modes, using a test translator, and actual spacecraft tracking where the spacecraft is at some distance from the DSN station. The results indicate that the proposed end-to-end tests will not accurately reflect the error that occurs during actual spacecraft tracking.

    The S-band Polarisation All-Sky Survey has observed the entire southern sky using the 64-m Parkes radio telescope at 2.3 GHz with an effective bandwidth of 184 MHz. The surveyed sky area covers all declinations δ ⩽ 0°. To analyse compact sources, the survey data have been re-processed to produce a set of 107 Stokes I maps with 10.75 arcmin resolution and the large scale emission contribution filtered out. In this paper, we use these Stokes I images to create a total intensity southern-sky extragalactic source catalogue at 2.3 GHz. The source catalogue contains 23 389 sources and covers a sky area of 16 600 deg2, excluding the Galactic plane for latitudes |b| Sky Survey source positions are typically accurate to within 35 arcsec. At a flux density of 225 mJy, the S-band Polarisation All-Sky Survey source catalogue is more than 95% complete, and 94% of S-band Polarisation All-Sky Survey sources brighter than 500 mJy beam-1 have a counterpart at lower frequencies.

  1. [New business model for medical specialists].

    Science.gov (United States)

    Houwen, L G H J Louis

    2013-01-01

    The reforms in the field of medical specialist care have important implications for the professional practice of medical specialists and their working relationship with the hospital. This leads to a considerable amount of pressure placed upon the way physicians have traditionally practiced their liberal professions, which is by forming partnerships and practicing from within the hospitals based on an admission agreement. As of 2015, the tax benefits for entrepreneurs will be abolished and the formation of regional partnerships will be discouraged. These developments not only pose threats but also offer opportunities for both the entrepreneurial medical specialist and the innovative hospital. In this article, the prospect of a future business model for specialist medical care will be outlined and explored by proposing three new organizational forms. The central vision of this model is that physicians who wish to retain their status of liberal professional practitioners in the twenty-first century should be more involved in the ownership structure of hospitals. The social importance of responsible patient care remains paramount.

    Goodnough, Lawrence Tim; Murphy, Michael F

    2016-12-01

    The changing focus of transfusion medicine (TM) toward the hospital rather than the blood center and the involvement of TM specialists in a wide range of patient blood management and other specialist activities in the hospital, rather than just blood bank activities, means that the training of the transfusion specialists of the future should be under constant review. We provide overviews of the current training programs of the Accreditation Council for Graduate Medical Education in the United States and the Joint Royal Colleges of Physicians Training Board in the United Kingdom, along with specific descriptions of our own training programs at Stanford and Oxford. The numbers of TM fellows in training annually in the United States and of those who attempt to attain board certification have increased substantially over the last 20 years, despite the profound reduction in blood utilization since 2009. These trends reflect increasing job and career opportunities in new activities, such as patient blood management at hospital-based transfusion services. This trend has been seen to a lesser extent in the United Kingdom, although the focus of TM is similarly switching to hospital-based transfusion services. Based on current trends, transfusion medicine is a growing and robust specialty in the United States but perhaps less so in the United Kingdom, increasingly with hospital-centered job opportunities for improving blood utilization and clinical outcomes. Establishing pediatric TM training programs and improving research training are further opportunities for training TM specialists. © 2016 AABB.

    2013-08-01

    This letter describes the fabrication and characterization of a fluidic patch antenna operating at the S-band frequency (4 GHz). The antenna prototype is composed of a nanocomposite material made by a liquid metal alloy (eutectic gallium indium) blended with single-wall carbon-nanotube (SWNTs). The nanocomposite is then enclosed in a polymeric substrate by employing the UV-assisted direct-writing technology. The fluidic antennas specimens feature excellent performances, in perfect agreement with simulations, showing an increase in the electrical conductivity and reflection coefficient with respect to the SWNTs concentration. The effect of the SWNTs on the long-term stability of antenna's mechanical properties is also demonstrated.

    2017-07-01

    Full Text Available Purpose: In the resent years the healthcare system has moved to inter-professional, cross-disciplinary, multi-person approach where the communications are very important for ensuring patient safety. Communication in health organisations needs to be studied and analysed deeply and comprehensively because the future of an organisation often depends on good communication. The purpose of this study is to investigate and analyse the reasons for ineffective communication between medical specialists in the teams they work in. Materials and Methods: A questionnaire method is used. Through a survey over a period of 12 months (from 01. 12. 2014 to 01. 12. 2015 at the Escullap Hospital in Pazardzhik, DCC 18 - Sofia, St. Mina Hospital in Plovdiv, MHAT – Plovdiv, DCC 1 in Haskovo, UMHAT in Stara Zagora, DCC 3 in Varna and MHAT – Parvomay, was studied and analyzed the opinion of medical specialists on the effectiveness of communication within the team they work in. The survey includes 477 medical specialists. Results and conclusions: According to 41.1% of the respondents, the communication in the team they work in is insufficiently effective. Most of the respondents (39.8% find their colleagues responsible for the ineffective communication, followed by those who seek the cause for poor communication in the management of the health care facility (27.6%. The leading cause of poor communication in the team according to the study participants is the inequality between the characters of the colleagues (41.9%. According to the majority of respondents (28.3%, improvements in facilities and wage increases (27.3% would be essential to improve communication within the team they work in. Recommendations have been formulated to improve communication among medical specialists.

  17. The predictability of phytophagous insect communities: host specialists as habitat specialists.

    Directory of Open Access Journals (Sweden)

    Jörg Müller

    Full Text Available The difficulties specialized phytophagous insects face in finding habitats with an appropriate host should constrain their dispersal. Within the concept of metacommunities, this leads to the prediction that host-plant specialists should sort into local assemblages according to the local environmental conditions, i.e. habitat conditions, whereas assemblages of host-plant generalists should depend also on regional processes. Our study aimed at ranking the importance of local environmental factors and species composition of the vegetation for predicting the species composition of phytophagous moth assemblages with either a narrow or a broad host range. Our database consists of 351,506 specimens representing 820 species of nocturnal Macrolepidoptera sampled between 1980 and 2006 using light traps in 96 strict forest reserves in southern Germany. Species were grouped as specialists or generalists according to the food plants of the larvae; specialists use host plants belonging to one genus. We used predictive canonical correspondence and co-correspondence analyses to rank the importance of local environmental factors, the species composition of the vegetation and the role of host plants for predicting the species composition of host-plant specialists and generalists. The cross-validatory fit for predicting the species composition of phytophagous moths was higher for host-plant specialists than for host-plant generalists using environmental factors as well as the composition of the vegetation. As expected for host-plant specialists, the species composition of the vegetation was a better predictor of the composition of these assemblages than the environmental variables. But surprisingly, this difference for specialized insects was not due to the occurrence of their host plants. Overall, our study supports the idea that owing to evolutionary constraints in finding a host, host-plant specialists and host-plant generalists follow two different models of

    2008-01-01

    Grounded cognition rejects traditional views that cognition is computation on amodal symbols in a modular system, independent of the brain's modal systems for perception, action, and introspection. Instead, grounded cognition proposes that modal simulations, bodily states, and situated action underlie cognition. Accumulating behavioral and neural evidence supporting this view is reviewed from research on perception, memory, knowledge, language, thought, social cognition, and development. Theories of grounded cognition are also reviewed, as are origins of the area and common misperceptions of it. Theoretical, empirical, and methodological issues are raised whose future treatment is likely to affect the growth and impact of grounded cognition.

  1. Impulse response characterization of the propagation and scattering environment in through-wall applications using an S-band noise radar

    Science.gov (United States)

    Smith, Sonny; Narayanan, Ram M.

    2012-06-01

    An ultrawideband (UWB) random noise radar operating at S-Band has been developed for through-wall detection, ranging, tracking, and imaging of targets. The system transmits a bandlimited UWB noise signal and accomplishes detection by cross-correlating the reflected signal with a time-delayed replica of the transmit signal. Noise radars have been found eminently suitable for most though-wall radar applications. Yet, in such scenarios, the antennas and the barrier (i.e. the wall) cause distortions in the return signal due to their frequency-dependent radiation and loss characteristics, respectively. In this paper, we explore the feasibility of characterizing the impulse response of various barriers and obstructions via measurements with the S-Band noise radar. As is well known, the entire operation of a linear system (e.g., antenna or barrier) can be captured in its impulse response h(t), i.e. the output of the system when excited by an impulse function at its input, δ(t). Thus, impulse response testing, generally, provides a complete diagnosis of the system over its entire mode of operation. This paper will present results on our impulse response characterization of the propagation and scattering environment through a barrier by the atypical method of cross correlation of noise signals. In addition, we will introduce a simple electromagnetic forward model for wall propagation and accompanying simulations.

    While e-learning has become an important tool in teaching medical students, the training of specialists in medical imaging is still dominated by lecture-based courses. To assess the potential of e-learning in specialist education in medical imaging. An existing lecture-based five-day course in Clinical Nuclear Medicine (NM) was enhanced by e-learning resources and activities, including practical exercises. An anonymized survey was conducted after participants had completed and passed the multiple choice electronic course examination. Twelve out of 15 course participants (80%) responded. Overall satisfaction with the new course format was high, but 25% of the respondents wanted more interactive elements such as discussions and practical exercises. The importance of lecture handouts and supplementary online material such as selected original articles and professional guidelines was affirmed by all the respondents (92% fully, 8% partially), while 75% fully and 25% partially agreed that the lectures had been interesting and relevant. E-learning represents a hitherto unrealized potential in the education of medical specialists. It may expedite training of medical specialists while at the same time containing costs.

The title 'clinical nurse specialist' (CNS) is used widely within health care services and describes a multitude of roles and service provision. Lack of role clarity impacts upon human resources, service delivery and the post holder. Patients, carers and health care professionals were invited to participate in focus groups. Groups sought information about the services provided by the CNS. The research adopted a grounded theory approach in order to generate a locally recognizable description of the services. From the data analysis eight technical services carried out by the CNSs emerged. Analysis also identified three areas where the CNS provided added value. The findings are discussed in relation to relevant literature. Recommendations are made concerning effective and efficient use of this important staff resource.

    Tingle, John; McHale, Jean

    Nurses are increasingly concerned with legal and ethical dilemmas in clinical decision-making. The law impacts across a wide range of issues in nursing practice. It is important for healthcare professionals to be aware of the way in which the law regulates their professional practice. In this article John Tingle and Jean McHale introduce a new series of articles on law for nurses. The series will feature contributions by legal academics who are specialists in the area of healthcare law. The series will outline basic issues such as the English legal system. It will then consider a wide range of issues, including nursing negligence, legal issues of expanded role, patient safety, consent to treatment, adults lacking mental capacity, mental health law, end-of-life decision-making, law and nursing research, resource allocation law and human rights.

    District nurse (DN) care delivery has undergone substantial change in recent years due to changing demographics and service delivery demands that have called for a move of care delivery from secondary to primary care. The title District Nurse is recorded with the Nursing and Midwifery Council (NMC) on completion of the Specialist Practice Qualification in District Nursing (SPQ DN), which purports to be a 'transformational' course that prepares future caseload holders to manage their team and prioritise care delivery effectively. This article explores the need for assertiveness skills in this role in response to Australian research, and outlines the pedagogic interventions implemented during the SPQ DN course to enhance this skill. Assertiveness scores were monitored for the duration of the course and demonstrated a significant increase-a topic that is now the subject of a future, funded study.

    There is growing demand to contain health care costs and to reassess the value of medical services. The traditional hospital, academic, and research roles of the infectious disease (ID) specialist are threatened, yet there is an increasing need for expertise because of growing antimicrobial resistance and emerging pathogens. Opportunities exist to develop and expand services for the care of patients infected with human immunodeficiency virus and in infection control, epidemiology, outcomes research, outpatient intravenous therapy, and resource management. It is important for ID physicians to appreciate the principles involved in managed care and the areas in which ID services can be valuable. To be effective, physicians need to know about tools such as practice guidelines, physician profiling, outcomes monitoring, computerized information management, risk sharing, networking, and marketing, as well as related legal issues. With a positive attitude toward learning, application, and leadership, ID physicians can redefine their role and expand their services through managed care.

    Full Text Available BACKGROUND: The inherent complexity of statistical methods and clinical phenomena compel researchers with diverse domains of expertise to work in interdisciplinary teams, where none of them have a complete knowledge in their counterpart's field. As a result, knowledge exchange may often be characterized by miscommunication leading to misinterpretation, ultimately resulting in errors in research and even clinical practice. Though communication has a central role in interdisciplinary collaboration and since miscommunication can have a negative impact on research processes, to the best of our knowledge, no study has yet explored how data analysis specialists and clinical researchers communicate over time. METHODS/PRINCIPAL FINDINGS: We conducted qualitative analysis of encounters between clinical researchers and data analysis specialists (epidemiologist, clinical epidemiologist, and data mining specialist. These encounters were recorded and systematically analyzed using a grounded theory methodology for extraction of emerging themes, followed by data triangulation and analysis of negative cases for validation. A policy analysis was then performed using a system dynamics methodology looking for potential interventions to improve this process. Four major emerging themes were found. Definitions using lay language were frequently employed as a way to bridge the language gap between the specialties. Thought experiments presented a series of "what if" situations that helped clarify how the method or information from the other field would behave, if exposed to alternative situations, ultimately aiding in explaining their main objective. Metaphors and analogies were used to translate concepts across fields, from the unfamiliar to the familiar. Prolepsis was used to anticipate study outcomes, thus helping specialists understand the current context based on an understanding of their final goal.

    2009-01-01

    Full Text Available Abstract Background Medical specialists are often seen as the first prescribers of new drugs. However, the extent to which specialists influence new drug prescribing in primary care is largely unknown. Methods This study estimates the influence of medical specialists on new drug prescribing in primary care shortly after market introduction. The influence of medical specialists on prescribing of five new drugs was measured in a cohort of 103 GPs, working in 59 practices, over the period 1999 until 2003. The influence of medical specialists on new drug prescribing in primary care was assessed using three outcome measures. Firstly, the proportion of patients receiving their first prescription for a new or reference drug from a specialist. Secondly, the proportion of GPs prescribing new drugs before any specialist prescribes to their patients. Thirdly, we compared the time until the GP's first own prescribing between GPs who waited for prescriptions from specialists and those who did not. Results The influence of specialists showed considerable differences among the new drugs studied. The proportion of patients receiving their first prescription from a specialist was greatest for the combination salmeterol/fluticasone (60.2%, and lowest for rofecoxib (23.0%. The proportion of GPs prescribing new drugs before waiting for prescriptions from medical specialists ranged from 21.1% in the case of esomeprazole to 32.9% for rofecoxib. Prescribing new drugs by specialists did not shorten the GP's own time to prescribing. Conclusion This study shows that the influence of medical specialists is clearly visible for all new drugs and often greater than for the existing older drugs, but the rapid uptake of new drugs in primary care does not seem specialist induced in all cases. GPs are responsible for a substantial amount of all early prescriptions for new drugs and for a subpopulation specialist endorsement is not a requisite to initiate in new drug prescribing

    2010-01-01

    The main objective of this study was to analyze pharmacy specialists' attitudes toward the quality of pharmaceutical services at Lithuanian community pharmacies. Between April and June 2009, a total of 471 Lithuanian community pharmacy specialists completed a questionnaire designed to evaluate their attitudes toward the quality of pharmaceutical services at community pharmacies. The main dimensions of pharmaceutical service quality were extracted by principal component analysis. Two main dimensions of pharmaceutical service quality were extracted: pharmacotherapeutic aspects (provision of information about drug therapy, possible side effects, health promotion, the amount of time spent with a patient, and the ascertainment that a patient understood the provided information) and socioeconomic aspects (considering patient's needs and financial capabilities, making a patient confident with the services provided). Pharmacy specialists evaluated the quality of both dimensions positively, but the quality of the first dimension was rated significantly worse than that of the second dimension. The attitudes of pharmacy specialists working at independent pharmacies were more positive toward pharmacotherapeutic aspects as compared to the specialists working at chain or state pharmacies. Pharmacotherapeutic aspects were rated better by pharmacy specialists, aged ≥ 55 years, than those younger than 45 years. Moreover, the attitudes of 45-54-year-old pharmacy specialists toward the socioeconomic aspects were more positive as compared with those of 35-44-year olds. Pharmacists rated the socioeconomic aspects of pharmaceutical service quality worse as compared with pharmacy technicians. The attitudes of pharmacy specialists working at pharmacies with 6-9 specialists were more negative toward pharmacotherapeutic aspects than those of the pharmacies with 1-2 specialists. Pharmacy specialists working at pharmacies with ≥ 10 specialists reported lower scores of socioeconomic

    The Moon radiates energy at infrared and microwave wavelengths, in addition to reflecting sunlight at optical wavelengths. As a result, an antenna pointed at or near the Moon will cause an increase in receiver noise temperature that needs to be accounted for in telemetry, radio science, or ranging link budgets. The Deep Space Network may be required to use its antennas in future lunar robotic or human missions, and thus it is important to understand the nature of this temperature increase as a function of observing frequency, lunar phase, and angular offset of the antenna beam from the center of the lunar disk. This article quantifies such a set of measurements acquired at DSS 13, a 34-m-diameter research and development beam-waveguide antenna located at Goldstone, California, at three different telecommunication frequencies, S-band (2.3 GHz), X-band (8.4 GHz), and Ka-band (32 GHz), over a wide range of lunar phase, for both disk-centered and limb-centered positions of the antenna beam.

    Heart rhythm (HR) management is rapidly developing as a subspecialty within cardiology and it is imperative to promote and ensure sufficient and homogeneous training and qualification among professionals in Europe. This encouraged the European Society of Cardiology, through the European Heart Rhythm Association (EHRA), to organize a European Core Curriculum for the HR specialist through the following: definition of the scope of the HR speciality (Syllabus), development of minimum standards and objectives for training in HR management (Curriculum), development of a model to certify HR professionals and teaching units (Accreditation), and development of a Registry for European HR accredited professionals and teaching units and their activity (Registries). The duration of the training period should be of a minimum of 2 years following general cardiology training. During this period, the trainee must develop the required knowledge, practical skills, behaviours, and attitudes to manage HR patients. The trainee must be involved in a minimum number of different procedures and achieve specified levels of competence. The training centre should be integrated within a full-service cardiology department. Assessment of the trainee and the training programmes should include reports by the training programme supervisor and the national society HR organizations, a logbook of procedures, written examinations, and assessment of professionalism. The EHRA presently requires the trainee to pass the EHRA accreditation exams (invasive EP and cardiac pacing and ICDs). Continuous learning and practice are required to maintain standards and practice because substantial changes may occur in clinical practice or the health-care environment.

    Full Text Available According to the National programme of agriculture and rural areas (2003. it is pointed out that the social-economic development of rural areas is remarkably interfered by their unsuitable educational structure and puts them behind with city inhabitants. It is also pointed out that the offer of programmes for professional development of education and improvement due to specific needs for education of adult rural population (especially farmers is proportionately low. Therefore, general needs for improvement of educational structure of farmers and rural population are extended, especially through the system of permanent professional education and improvement for requirements of family farming and rural population as are specialist seminars at College of Agriculture in Križevci for farmers. Such training colleges have been conducting here since 2004. Until now, 298 trainees have finished such form of education. They were organised in collaboration with 9 agricultural associations. Sex, age and educational structure of trainees as well as average number of people engaged in farming for 213 trainees organized in collaboration with 6 agricultural associations were analysed by this study. They finished training colleges during 2004th and 2005th year. Analysed data was obtained from questionnaire that summaries the most frequent comments and suggestions as the most important guidance for further organisation of such form of education.

    Mental health peer specialists develop peer-to-peer relationships of trust with clients to improve their health and well-being, functioning in ways similar to community health workers. Although the number of peer specialists in use has been increasing, their role in care teams is less defined than that of the community health worker. This qualitative study explored how the peer specialist role is defined across different stakeholder groups, the expectations for this role and how the peer specialist is utilised and integrated across different types of mental health services. Data were collected through interviews and focus groups conducted in Massachusetts with peer specialists (N = 44), their supervisors (N = 14) and clients (N = 10) between September 2009 and January 2011. A consensus coding approach was used and all data outputs were reviewed by the entire team to identify themes. Peer specialists reported that their most important role is to develop relationships with clients and that having lived mental health experience is a key element in creating that bond. They also indicated that educating staff about the recovery model and peer role is another important function. However, they often felt a lack of clarity about their role within their organisation and care team. Supervisors valued the unique experience that peer specialists bring to an organisation. However, without a defined set of expectations for this role, they struggled with training, guiding and evaluating their peer specialist staff. Clients reported that the shared lived experience is important for the relationship and that working with a peer specialist has improved their mental health. With increasing support for person-centred integrated healthcare delivery models, the demand for mental health peer specialist services will probably increase. Therefore, clearer role definition, as well as workforce development focused on team orientation, is necessary for peer specialists to be fully integrated

    Full Text Available Although recent research suggests that the selective nature of new media helps foster issue specialists, little empirical evidence has been documented, mostly due to theoretical and methodological limitations. Extending the concept of issue publics, the present study proposes a method to estimate the degree to which an individual is a specialist- or a generalist-type citizen. Applying the method to the 2008 American National Election Studies data, the study reveals various characteristics of specialists and generalists. The results indicate that specialist-type citizens are positively associated with online news use, but negatively associated with conventional news media, such as television, newspaper, and radio. The implications of the growth of specialists as well as the validity of the proposed method are discussed.

    The American College of Clinical Pharmacy and other stakeholder organizations seek to advance clinical pharmacist practitioners, educators, and researchers. Unfortunately, there remains an inadequate supply of residency-trained clinical specialists to meet the needs of our health care system, and nonspecialists often are called on to fill open specialist positions. The impact of clinical pharmacy specialists on pharmacotherapy outcomes in both acute care and primary care settings demonstrates the value of these specialists. This commentary articulates the need for postgraduate year two (PGY2)-trained clinical specialists within the health care system by discussing various clinical and policy rationales, interprofessional support, economic justifications, and their impact on quality of care and drug safety. The integrated practice model that has grown out of the American Society of Health-System Pharmacists Pharmacy Practice Model Initiative (PPMI) could threaten the growth and development of future clinical specialists. Therefore, the ways in which PGY2-trained clinical pharmacist specialists are deployed in the PPMI require further consideration. PGY2 residencies provide education and training opportunities that cannot be achieved in traditional professional degree programs or postgraduate year one residencies. These specialists are needed to provide direct patient care to complex patient populations and to educate and train pharmacy students and postgraduate residents. Limitations to training and hiring PGY2-trained clinical pharmacy specialists include site capacity limitations and lack of funding. A gap analysis is needed to define the extent of the mismatch between the demand for specialists by health care systems and educational institutions versus the capacity to train clinical pharmacists at the specialty level. © 2014 Pharmacotherapy Publications, Inc.

    The purpose of the study is to examine the issue of smoking among patients of selected clinics of the Miedzylesie Specialist Hospital in Warsaw, assessment of nicotine addiction of smokers and motivation to give up smoking. The survey was carried out in June and July 2009 after obtaining the consent of the Director of Miedzylesie Specialist Hospital in Warsaw. The survey was participated in by 100 patients of selected specialist clinics. The survey was carried out on the basis of a questionnaire consisting of 7 questions. Furthermore, the "Test of motivation to give up smoking" (Schneider's test) and the "Assessment of nicotine addiction level" (Fagerström's test), published in the "Consensus regarding recognition and treatment of nicotine addiction", were used. When processing data, the descriptive statistics were applied. Those surveyed included 53 former cigarette smokers 47 active smokers and. In the group of former smokers, 19 people still were exposed to passive smoking. In the past, the problem regarded 41 people. Thirty former smokers smoked cigarettes among non-smokers, including young children (18 people) and when pregnant and breastfeeding (2 people). Also 30 respondents smoked despite medical contraindications and bad conscience. For 27 people, expenditures on cigarettes constituted a considerable burden of their respective household budgets, and 20 said that it was a significant item in their expenditures. Smokers have been smoking cigarettes for 30 years, on average 20 cigarettes a day. Those patients began to smoke at the age of 20. Thirty one active smokers exposed other people to passive smoking and 38 respondents smoked cigarettes despite medical contraindications and with bad conscience. For 22 people, expenditures related to smoking are a considerable burden of the household budget and for 21 people, it is a significant expenditure. Almost one half of the patients smoke cigarettes although they should brake off smoking for medical reasons. Most

    In 1997 the Royal College of Paediatrics and Child Health introduced portfolios to guide and monitor the learning of specialist registrars. We studied their value for assessment. Using Bigg's SOLO criteria we devised a marking scheme based on 6 domains of competence: clinical, communication, teaching and learning, ethics and attitudes, management and evaluation, and creation of evidence. We rated portfolios according to quality of evidence presented and expectations by year of training. We similarly assessed trainee performance in the annual record of in-training assessment (RITA) interview. Specific advice based on the results of the first portfolio assessments was circulated to all trainees, instructing them to increase the structure and decrease the bulk of portfolios. A second sample of portfolios was reviewed a year later, using similar evaluations, to determine the effects. A total of 76 portfolios were assessed in year 1 by a single rater; 30 portfolios were assessed in year 2 by 2 independent raters. The quality of documentation improved from year 1 to year 2 but there was no significant increase in portfolio scores. The inter-rater correlation coefficient of the portfolio assessment method was 0.52 (Cohen's kappa 0.35). The inter-rater correlation coefficient of the RITA interview was 0.71 (Cohen's kappa 0.38). There was moderate inter-assessment correlation between portfolios and RITA interviews (kappa 0.26 in year 1 and 0.29 in year 2). Generalisability analysis suggested that 5 successive ratings by a single observer or independent ratings by 4 observers on the same occasion would be needed to yield a generalisability coefficient > 0.8 for overall portfolio rating. This method of portfolio assessment is insufficiently reliable as a sole method for high stakes, single-instance assessment, but has a place as part of a triangulation process. Repeated portfolio assessment by paired observers would increase reliability. Longer term studies are required to

    The COMIS workshop (Conjunction of Multizone Infiltration Specialists) was a joint research effort to develop a multizone infiltration mode. This workshop (October 1988--September 1989) was hosted by the Energy Performance of Buildings Group at Lawrence Berkeley Laboratory's Applied Science Division. The task of the workshop was to develop a detailed multizone infiltration program taking crack flow, HVAC-systems, single-sided ventilation and transport mechanism through large openings into account. This work was accomplished not by investigating into numerical description of physical phenomena but by reviewing the literature for the best suitable algorithm. The numerical description of physical phenomena is clearly a task of IEA-Annex XX Air Flow Patterns in Buildings,'' which will be finished in September 1991. Multigas tracer measurements and wind tunnel data will be used to check the model. The agenda integrated all participants' contributions into a single model containing a large library of modules. The user-friendly program is aimed at researchers and building professionals. From its announcement in December 1986, COMIS was well received by the research community. Due to the internationality of the group, several national and international research programmes were co-ordinated with the COMIS workshop. Colleagues for France, Italy, Japan, The Netherlands, People's Republic of China, Spain, Sweden, Switzerland, and the United States of America were working together on the development of the model. Even though this kind of co-operation is well known in other fields of research, e.g., high energy physics; for the field of building physics it is a new approach. This document contains an overview about infiltration modelling as well as the physics and the mathematics behind the COMIS model. 91 refs., 38 figs., 9 tabs.

    针对麦穗出现后小麦生长期的微波散射特性,基于矢量辐射传输理论(VRT),建立了小麦S波段多层后向散射模型。模型把小麦冠层划分为麦穗层、麦秆叶层和土壤层,并基于能量守恒的矢量辐射传输理论,对电磁波强度的反射、吸收和传输进行了分析,采用5项后向散射贡献构成冠层总后向散射。模型的解析首先采用先进积分方程模型(AIEM)对土壤粗糙面的后向散射进行模拟,然后利用消光矩阵和相矩阵分别计算散射能量的衰减和散射方向的变化,最后利用Mueller矩阵获得最终的解析解。该文选用2011年川西实验场测量的小麦S波段散射数据对构建的模型进行验证与分析,模型的模拟值与实测值吻合较好。研究结果表明麦穗出现后对小麦冠层后向散射影响较大,建模时有必要单独考虑麦穗的影响。%The paper presents a multiple layers backscatter model of wheat for S-band based on vector radiative transfer (VRT) theory, which focuses on the microwave character of wheat at the growth stage that wheat ears appeared. The scattered, absorbed and transferred electromagnetic intensity is analyzed based on the law of energy conservation of VRT, and the wheat canopy is divided into three layers, the ears layer, the stem and leaf layer and the soil layer. Furthermore, the total backscatter is composed by using five back-scattering contributions. An advanced integral equation model (AIEM) is applied to simulate the soil backscatter. The extinction and phase matrices are used to compute the scattering intensity decayed and transferred. In addition, Mueller matrix is used to obtain the backscatter values. The backscatter of S-band, which was measured at the West Sichuan Experiment Location in 2011, is applied to analyze and verify the model. The results show the simulated values agreed well with the measured data, and the wheat ears should be taken into account in

    To explore health care provider (HCP) perspectives on the coordination of cancer care between FPs and cancer specialists. Qualitative study using semistructured telephone interviews. Canada. A total of 58 HCPs, comprising 21 FPs, 15 surgeons, 12 medical oncologists, 6 radiation oncologists, and 4 GPs in oncology. This qualitative study is nested within a larger mixed-methods program of research, CanIMPACT (Canadian Team to Improve Community-Based Cancer Care along the Continuum), focused on improving the coordination of cancer care between FPs and cancer specialists. Using a constructivist grounded theory approach, telephone interviews were conducted with HCPs involved in cancer care. Invitations to participate were sent to a purposive sample of HCPs based on medical specialty, sex, province or territory, and geographic location (urban or rural). A coding schema was developed by 4 team members; subsequently, 1 team member coded the remaining transcripts. The resulting themes were reviewed by the entire team and a summary of results was mailed to participants for review. Communication challenges emerged as the most prominent theme. Five key related subthemes were identified around this core concept that occurred at both system and individual levels. System-level issues included delays in medical transcription, difficulties accessing patient information, and physicians not being copied on all reports. Individual-level issues included the lack of rapport between FPs and cancer specialists, and the lack of clearly defined and broadly communicated roles. Effective and timely communication of medical information, as well as clearly defined roles for each provider, are essential to good coordination of care along the cancer care trajectory, particularly during transitions of care between cancer specialist and FP care. Despite advances in technology, substantial communication challenges still exist. This can lead to serious consequences that affect clinical decision making

  4. Classification and modeling of human activities using empirical mode decomposition with S-band and millimeter-wave micro-Doppler radars

    The ability to identify human movements can be an important tool in many different applications such as surveillance, military combat situations, search and rescue operations, and patient monitoring in hospitals. This information can provide soldiers, security personnel, and search and rescue workers with critical knowledge that can be used to potentially save lives and/or avoid a dangerous situation. Most research involving human activity recognition is focused on using the Short-Time Fourier Transform (STFT) as a method of analyzing the micro-Doppler signatures. Because of the time-frequency resolution limitations of the STFT and because Fourier transform-based methods are not well-suited for use with non-stationary and nonlinear signals, we have chosen a different approach. Empirical Mode Decomposition (EMD) has been shown to be a valuable time-frequency method for processing non-stationary and nonlinear data such as micro-Doppler signatures and EMD readily provides a feature vector that can be utilized for classification. For classification, the method of a Support Vector Machine (SVMs) was chosen. SVMs have been widely used as a method of pattern recognition due to their ability to generalize well and also because of their moderately simple implementation. In this paper, we discuss the ability of these methods to accurately identify human movements based on their micro-Doppler signatures obtained from S-band and millimeter-wave radar systems. Comparisons will also be made based on experimental results from each of these radar systems. Furthermore, we will present simulations of micro-Doppler movements for stationary subjects that will enable us to compare our experimental Doppler data to what we would expect from an "ideal" movement.

  5. The reflectivity in the S-band and the broadband ultrasonic spectroscopy as new tools for the study of water relations in Vitis vinifera L.

    The large water requirements of Vitis vinifera L. together with an increase in temperature and drought events imply the need for irrigation in the driest areas of its distribution range. Generous watering may reduce grape quality so irrigation should be precisely regulated through the development of new methods of accurate irrigation scheduling based on plant 'stress sensing'. Two new methods, the reflectivity in the S-band and the broadband ultrasonic spectroscopy, can be used as non-invasive and reproducible techniques for the study of plant water relations in V. vinifera. On one hand, the measurement of reflectance at frequencies around 2.4 GHz gives an excellent accuracy when the changes in the existing area (S) between two reflectance curves are correlated with the relative water content (RWC). On the other hand, an improvement of the broadband ultrasonic spectroscopy based on the enlargement of the analysis frequency window provides, apart from the determination of the turgor loss point (TLP), additional information about the leaves without additional computational cost or additional leaf information requirements. Before TLP, the frequency associated with the maximum transmittance (f/f(o)), the macroscopic elastic constant of the leaf in the Z direction (c(33)) and, specially, the variation of the attenuation coefficient with the frequency (n), were highly correlated with changes in RWC. Once turgor is lost, a shift in the parameters directly related to the attenuation of the signal was also observed. The use of both techniques allows for a more convincing knowledge of the water status in V. vinifera.

    To identify ways to improve cancer care for older patients, we set out to examine how older patients in the Netherlands are currently being evaluated prior to oncological treatment and to explore the potential obstacles in the incorporation of a geriatric evaluation, using a web-based survey sent to Dutch medical oncology specialists and oncology nursing specialists. The response rate was 34% (183 out of 544). Two-thirds of respondents reported that a geriatric evaluation was being used, although primarily on an ad hoc basis only. Most respondents expressed a desire for a routine evaluation or more intensive collaboration with the geriatrician and 86% of respondents who were not using a geriatric evaluation expressed their interest to do so. The most important obstacles were a lack of time or personnel and insufficient availability of a geriatrician to perform the assessment. Thus, over 30% of oncology professionals in the Netherlands express an interest in geriatric oncology. Important obstacles to a routine implementation of a geriatric evaluation are a lack of time, or insufficient availability of geriatricians; this could be overcome with policies that acknowledge that quality cancer care for older patients requires the investment of time and personnel.

  9. Nuclear Hyperfine and Quadrupole Tensor Characterization of the Nitrogen Hydrogen Bond Donors to the Semiquinone of the QB Site in Bacterial Reaction Centers: A Combined X- and S-Band 14,15N ESEEM and DFT Study

    2015-01-01

    The secondary quinone anion radical QB– (SQB) in reaction centers of Rhodobacter sphaeroides interacts with Nδ of His-L190 and Np (peptide nitrogen) of Gly-L225 involved in hydrogen bonds to the QB carbonyls. In this work, S-band (∼3.6 GHz) ESEEM was used with the aim of obtaining a complete characterization of the nuclear quadrupole interaction (nqi) tensors for both nitrogens by approaching the cancelation condition between the isotropic hyperfine coupling and 14N Zeeman frequency at lower microwave frequencies than traditional X-band (9.5 GHz). By performing measurements at S-band, we found a dominating contribution of Nδ in the form of a zero-field nqi triplet at 0.55, 0.92, and 1.47 MHz, defining the quadrupole coupling constant K = e2qQ/4h = 0.4 MHz and associated asymmetry parameter η = 0.69. Estimates of the hyperfine interaction (hfi) tensors for Nδ and Np were obtained from simulations of 1D and 2D 14,15N X-band and three-pulse 14N S-band spectra with all nuclear tensors defined in the SQB g-tensor coordinate system. From simulations, we conclude that the contribution of Np to the S-band spectrum is suppressed by its strong nqi and weak isotropic hfi comparable to the level of hyperfine anisotropy, despite the near-cancelation condition for Np at S-band. The excellent agreement between our EPR simulations and DFT calculations of the nitrogen hfi and nqi tensors to SQB is promising for the future application of powder ESEEM to full tensor characterizations.

    Full Text Available In this study we apply the versatile/specialist offender debate to the research of intimate partner violence. We propose the existence of two types of imprisoned male batterers: the generalist and the specialist batterer. The individual, family, and community characteristics of these types of batterers are further explored in 110 imprisoned males in the Penitentiary of Villabona (Spain. As for the individual characteristics, results indicate that the generalist batterer present higher levels of psychopathology (specially antisocial and borderline personality, sexist attitudes, and substance dependence. Specialist batterers presented higher levels of conflict in their family of origin. Finally, generalist batterers reported coming from more socially disordered communities and showed lower levels of participation and integration in these communities than the specialist batterer. These results suggest that the classical distinctions among batterers based on psychopathology and context of violence (whether general or family only might be of little utility when applied to imprisoned male batterers.

    A cavity-type beam position monitor (BPM) has been developed for a compact terahertz (THz) free-electron laser (FEL) system and ultra-short pulsed electron Linac system at the Korea Atomic Energy Research Institute (KAERI). Compared with other types of BPMs, the cavity-type BPM has higher sensitivity and faster response time even at low charge levels. When electron beam passes through the cavity-type BPM, it excites the dipole mode of the cavity of which amplitude depends linearly on the beam offset from the center of the cavity. Signals from the BPM were measured as a function of the beam offset by using an oscilloscope. The microtron accelerator for the KAERI THz FEL produces the electron beam with an energy of 6.5 MeV and pulse length of 5 μs with a micropulse of 10-20 ps at the frequency of 2.801 GHz. The macropulse beam current is 40 mA. Because the microtron provides multi-bunch system, output signal would be the superposition of each single bunch. So high output signal can be obtained from superposition of each single bunch. The designed position resolution of the cavity-type BPM in multi-bunch is submicron. Our cavity-type BPM is made of aluminum and vacuum can be maintained by indium sealing without brazing process, resulting in easy modification and cost saving. The resonance frequency of the cavity-type BPM is 2.803 GHz and the cavity-type BPM dimensions are 200 × 220 mm (length × height) with a pipe diameter of 38 mm. The measured position sensitivity was 6.19 (mV/mm)/mA and the measured isolation between the X and Y axis was -39 dB. By measuring the thermal noise of system, position resolution of the cavity-type BPM was estimated to be less than 1 μm. In this article, we present the test results of the S-band cavity-type BPM and prove the feasibility of the beam position measurement with high resolution using this device.

Using a multinomial model based on estimated species relative abundance in two habitats, our method minimizes bias due to differences in sampling intensities between two habitat types...... as well as bias due to insufficient sampling within each habitat. The method permits a robust statistical classification of habitat specialists and generalists, without excluding rare species a priori. Based on a user-defined specialization threshold, the model classifies species into one of four groups...... fraction (57.7%) of bird species with statistical confidence. Based on a conservative specialization threshold and adjustment for multiple comparisons, 64.4% of tree species in the full sample were too rare to classify with confidence.

    Hepatitis B is a viral infection primarily affecting people from culturally diverse communities in Australia. While vaccination prevents infection, there is increasing mortality resulting from liver damage associated with chronic infection. Deficits in the national policy and clinical response to hepatitis B result in a low diagnosis rate, inadequate testing and diagnosis processes, and poor access to hepatitis B treatment services. While research identifies inadequate hepatitis B knowledge among people with the virus and primary health care workers, this project sought to identify how specialist clinicians in Australia negotiate cultural diversity, and provide often complex clinical information to people with hepatitis B. A vignette was developed and presented to thirteen viral hepatitis specialist clinicians prior to an electronically recorded interview. Recruitment continued until saturation of themes was reached. Data were thematically coded into themes outlined in the interview schedule. Ethical approval for the research was provided by the La Trobe University Human Research Ethics Committee. Key messages provided to patients with hepatitis B by clinical specialists were identified. These messages were not consistently provided to all patients with hepatitis B, but were determined on perceptions of patient knowledge, age and highest educational level. While the vignette stated that English was not an issue for the patient, most specialists identified the need for an interpreter. Combating stigma related to hepatitis B was seen as important by the specialists and this was done through normalising the virus. Having an awareness of different cultural understandings about hepatitis B specifically, and health and well-being generally, was noted as a communication strategy. Key core competencies need to be developed to deliver educational messages to people with hepatitis B within clinical encounters. The provision of adequate resources to specialist clinics will

    Prey choice is often evaluated at the species or population level.Here,we analyzed the diet of octopuses of different populations with the aim to assess the importance of individual feeding habits as a factor affecting prey choice.Two methods were used,an assessment of the extent to which an individual octopus made choices of species representative of those population (PSi and IS) and 25% cutoff values for number of choices and percentage intake of individual on their prey.In one population of Octopus cf vulgaris in Bermuda individuals were generaiist by IS=0.77,but most chose many prey of the same species,and were specialists on it by >75% intake.Another population had a wider prey selection,still generalist with PSi=0.66,but two individuals specialized by choices.In Bonaire,there was a wide range of prey species chosen,and the population was specialists by IS=0.42.Individual choices revealed seven specialists and four generalists.A population of Octopus cyanea in Hawaii all had similar choices of crustaceans,so the population was generalist by IS with 0.74.But by individual choices,three were considered a specialist.A population of Enteroctopus dofleini from Puget Sound had a wide range of preferences,in which seven were also specialists,IS=0.53.By individual choices,thirteen were also specialists.Given the octopus specialty of learning during foraging,we hypothesize that both localized prey availability and individual personality differences could influence the exploration for prey and this translates into different prey choices across individuals and populations showed in this study.

    The Society for Academic Specialists in General Obstetrics and Gynecology was recently formed to meet the professional needs of general obstetrician-gynecologists (ob-gyns) in academic settings. Historically there has been little communication and poor networking among this group, largely as a result of lack of infrastructure. Until the Society for Academic Specialists in General Obstetrics and Gynecology, there has been no common venue to unite academic specialists nor a means to identify colleagues and develop professional relationships. The Society is creating avenues for communication and collaboration among general ob-gyn faculty across institutions. The Society for Academic Specialists in General Obstetrics and Gynecology is hosting national meetings, conducting workshops and webinars, and developing other media to promote research training, share administrative skills, and help members to become more effective educators. One major focus of the new organization is to provide resources to facilitate faculty development. Formation of the Society for Academic Specialists in General Obstetrics and Gynecology is particularly timely given that ob-gyns, without subspecialty fellowship training, have assumed major roles in academic departments. Their contribution to educational, scholarly, and clinical responsibilities is a significant benefit to the well-being of the departments of obstetrics and gynecology. In turn, the role of educator and scholar is of value to the general academic ob-gyn. The Society for Academic Specialists in General Obstetrics and Gynecology will help academic faculty and their institutions by filling current gaps in professional and career development, which should improve scholarship, enhance retention, and improve the ability for academic departments to fulfill their educational and clinical missions.

    Full Text Available Background Rare or narrowly endemic organisms are difficult to monitor and conserve when their total distribution and habitat preferences are incompletely known. One method employed in determining distributions of these organisms is species distribution modeling (SDM. Methods Using two species of narrowly endemic burrowing crayfish species as our study organisms, we sought to ground validate Maxent, a commonly used program to conduct SDMs. We used fine scale (30 m resolution rasters of pertinent habitat variables collected from historical museum records in 2014. We then ground validated the Maxent model in 2015 by randomly and equally sampling the output from the model. Results The Maxent models for both species of crayfish showed positive relationships between predicted relative occurrence rate and crayfish burrow abundance in both a Receiver Operating Characteristic and generalized linear model approach. The ground validation of Maxent led us to new populations and range extensions of both species of crayfish. Discussion We conclude that Maxent is a suitable tool for the discovery of new populations of narrowly endemic, rare habitat specialists and our technique may be used for other rare, endemic organisms.

    2016-05-01

    The entrance of newly qualified medical specialists into daily practice is considered to be a stressful period in which curriculum support is absent. Although engaging in both personal and professional learning and development activities is recognized fundamental for lifelong professional competence, research on medical professionals' entrance into practice is scarce. This research aims to contribute to the framework of medical professionals' informal learning and outlines the results of an exploratory study on the nature of learning in daily practice beyond postgraduate training. Eleven newly qualified physicians from different specialized backgrounds participated in a phenomenographic study, using a critical incident method and a grounded theory approach. Results demonstrated that learning in the workplace is, to a large extent, informal and associated with a variety of learning experiences. Analysis shows that experiences related to diagnostics and treatments are important sources for learning. Furthermore, incidents related to communication, changing roles, policy and organization offer learning opportunities, and therefore categorized as learning experiences. A broad range of learning activities are identified in dealing with these learning experiences. More specifically, actively engaging in actions and interactions, especially with colleagues of the same specialty, are the most mentioned. Observing others, consulting written sources, and recognizing uncertainties, are also referred to as learning activities. In the study, interaction, solely or combined with other learning activities, are deemed as very important by specialists in the initial entrance into practice. These insights can be used to develop workplace structures to support the entrance into practice following postgraduate training.

    Piasecki, Marie; Welch, Bryan; Mueller, Carl

    2015-01-01

    In 2015, the Space Communications and Navigation (SCaN) Testbed project completed an S-Band ground station located at the NASA Glenn Research Center in Cleveland, Ohio. This S-Band ground station was developed to create a fully characterized and controllable dynamic link environment when testing novel communication techniques for Software Defined Radios and Cognitive Communication Systems. In order to provide a useful environment for potential experimenters, it was necessary to characterize various RF devices at both the component level in the laboratory and at the system level after integration. This paper will discuss some of the laboratory testing of the ground station components, with a particular focus emphasis on the near-field measurements of the antenna. It will then describe the methodology for characterizing the installed ground station at the system level via a Tracking and Data Relay Satellite (TDRS), with specific focus given to the characterization of the ground station antenna pattern, where the max TDRS transmit power limited the validity of the non-noise floor received power data to the antenna main lobe region. Finally, the paper compares the results of each test as well as provides lessons learned from this type of testing methodology.

  9. Subject Specialist Mentors in the Lifelong Learning Sector: The Subject Specialist Mentor Model; is it working? A case study approach

    Directory of Open Access Journals (Sweden)

    Bailey, Wayne

    2011-01-01

    Full Text Available This short article explores whether using a mentoring model supports our Subject Specialist Mentors (SSMs with their role of mentoring trainees on Initial Teacher Training (ITT courses. Although there are many mentoring models to choose from, our model is based around mentoring within the Lifelong Learning Sector (LLS where trainees need support for their subject specialism as well as their generic teaching skills. The main focus is the use of coaching and mentoring skills taking into consideration guiding, supporting and challenging the trainee during the lifetime of the mentor/trainee relationship. The SSMs found that using our model as a tool helped to structure meetings and to ensure that the trainee had the necessary support to enable them to become proficient, competent subject specialist teachers. In conclusion, it was found that there is a need for the use of a model or a framework to help the Subject Specialist Mentor (SSM with such an important role.

  17. Seed dispersal by specialist versus generalist foragers: the plant's perspective

    Science.gov (United States)

    Larson, D.L.

    1996-01-01

    I examined the seed dispersal ecology of the stem parasitic plant, desert mistletoe (Phoradendron californicum, Viscaceae), with the objectives of (1) determining the relative effectiveness of specialist and generalist foragers for seed dispersal, (2) determining the extent to which desert mistletoe fruiting characteristics correspond to those predicted for plants attracting specialist versus generalist foragers, and (3) examining the potential consequences of the observed dispersal strategy for mistletoe reproduction. Three species of birds, phainopepla, Gila woodpecker, and northern mockingbird, fed on desert mistletoe at my study site. The specialist, phainopepla, was the most abundant and the most likely to perch in host species, where defecated seeds had a greater probability of lodging in a site suitable for establishment. Gila woodpeckers, although abundant, spent little time in host plants, thus dooming most of the seeds they consumed. Mockingbirds may disperse a small number of seeds, but were abundant enough to consume only a small portion of the available fruits. As expected for plants attracting specialist frugivores, mistletoes produced fruits throughout the 6-month season in which phainopeplas reside in the Sonoran desert. Contrary to expectation, numbers of fruits produced far exceeded the amount that could be consumed by the frugivores at my study site. Fruit crop size was positively related to absolute fruit removal, but not to proportional removal at the scale of the entire study site. However, crop size was positively related to proportional removal within the neighborhood of mistletoes occupying an individual host tree. Frugivores were attracted to infected hosts, host attractiveness increased, although proportional removal of fruit declined, with number of female mistletoes. The observed dispersal ecology of desert mistletoe suggests the likelihood of increasingly clumped distributions of mistletoe plants, as more and more seeds are deposited

  18. Asthma consultations with specialists: what do the pediatricians seek?

    Poowuttikul, Pavadee; Kamat, Deepak; Thomas, Ronald; Pansare, Milind

    2011-01-01

    "Expert Panel Report 3 (EPR-3): Guidelines for the Diagnosis and Management of Asthma" includes guidelines for referral to an asthma specialist. Because most cases of asthma are managed by primary care physicians, we intended to explore the referral practices of pediatricians managing childhood asthma. This study was designed to identify important considerations by pediatricians while referring a child to an asthma specialist. An electronic survey was sent to 1200 graduated pediatricians enlisted in the Michigan Chapter, American Academy of Pediatrics directory. The questions explored asthma disease characteristics, physician preferences when referring children with asthma, and reasons and barriers for asthma consultations. All responses were collected anonymously. We received 240/1200 (20%) questionnaires. The majority of pediatricians considered referral to a specialist if a child had severe persistent asthma (201/236 [85.2%]) or had a single life-threatening asthma event (188/229 [82.1%]). The top two likely reasons of referral included poor asthma control (200/224 [89.3%]) and unclear diagnosis (139/224 [62.1%]). We found 74/219 (33.8%) preferred consultation to a pediatric pulmonologist when compared with 93/219 (42.5%) allergists. We found the minority of pediatricians "always" recommended referral to a specialist for the following reasons: allergy skin testing (30/222 [13.5%]), possible allergen immunotherapy (54/223 [24.2%]), and spirometry (26/221 [11.8%]). The major barrier for childhood asthma specialist consultations was issues with medical insurance coverage (137/205 [66.8%]). Allergists have to educate primary care providers about the importance of allergen control, role of allergen immunotherapy, and updating current asthma treatment guidelines when treating a child with allergic asthma.

    The authors present a method for measuring the temperature-depth profile in a lossy material by applying Kalman algorithm to radiometric signals. The method employs a correlation microwave radiometer. It uses both short-range weighting functions and the delay times of the correlator. An experimental verification of this new thermal inversion approach is presented. The thermal noise is received in the microwave domain, by a S band radiometer by using an automatic experimental bench. A feature of this method is that it can be used in biomedical applications.

    2015-08-01

    General contextOne hundred years ago, almost nobody imagine a life without stars every night even in the urban areas. Now, to see a starry sky is a special event for urban citizens.It is possible to see the stars even inside cities? Yes, but for that we need star parks and lighting specialists as partners.Educational aspectThe citizens must be able to identify the planets, constellations and other celestial objects in their urban residence. This is part of a basic education. The number of the people living in the urban area who never see the main constellations or important stars increase every year. We must do something for our urban community.What is an urban star park?An urban public park where we can see the main constellations can be considered an urban star park. There can be organized a lot of activities as practical lessons of astronomy, star parties, etc.Classification of the urban star parksA proposal for classification of the urban star parks taking in consideration the quality of the sky and the number of the city inhabitants:Two categories:- city star parks for cities with inhabitants- metropolis star parks for cities with > 100.000 inhabitantsFive levels of quality:- 1* level = can see stars of at least 1 magnitude with the naked eyes- 2* level = at least 2 mag- 3* level = at least 3 mag- 4* level= at least 4 mag- 5* level = at least 5 magThe urban star urban park structure and lighting systemA possible structure of a urban star park and sky-friend lighting including non-electric illumination are descripted.The International Commission on IlluminationA description of this structure which has as members national commissions from all over the world.Dark-sky activists - lighting specialistsNational Commissions on Illumination organize courses of lighting specialist.

    Science.gov (United States)

    Danilova, K V; Razdorskaia, I M

    2014-01-01

    The objective of the present work was to study the stereotypes of addressing such a serious medical problem as the treatment of allergic rhinitis by practicing physicians and the development of criteria for the priority choice of pharmaceutical products to be prescribed to the patients presenting with this pathology. This pharmacoepidemiological investigation was designed to elucidate the preferences shown by specialists dealing with this disease. The special questionnaire was developed to collect and analyse the opinions of otorhinolaryngologists and allergologists. The study has demonstrated that both therapy of allergic rhinitis and preferences of specialists conform with the respective international standards. However, the study revealed the lack of the adequate communicative and informational interactions between two basic components of the healthcare system, viz. doctors and pharmacists. The authors emphasize the necessity to optimize professional approaches to the management of allergic rhinitis.

    2012-01-01

    Valve disease is common and is increasing in prevalence as the population ages. The delivery of appropriate management is not always straightforward, and better ways of organizing care are required. Here, the argument is made for a specialist multidisciplinary valve clinic, while a description is provided of the authors' model clinic, which incorporates a specialist cardiologist in addition to sonographers and a nurse who carry out the surveillance services. The clinic is based at a cardiothoracic center and one district hospital, but could be generalized. Previous audits have shown that this model can reduce the number of patients seen by a cardiologist, thus improving the safety and quality of treatment compared to conventional clinics.

  6. Defining the unique role of the specialist district nurse practitioner.

    Due to the reorganization of primary care trusts across the country, certain trusts proposed a reduction in the specialist district nurse practitioner numbers in favour of less qualified community nurses and health care assistants. Such proposals in one PCT were blocked, partly in response to documentation compiled by practitioners at the sharp end of nursing practice. With the new agenda of practice based commissioning, it is imperative that commissioners and management alike are aware of the scope of specialist district nurse practitioners. This is the first of a series of articles looking at specific case histories where the role of the district nurse is highlighted. It is the intention to stress the importance of the clinical expertise and confidence required by the district nurse to care for patients with complex needs in the community.

    2012-05-01

    Over the past few years, sports-related concussion has received significant media attention making it one of the most, if not highest profile neurological disorder. Thirty-one states now have passed sports concussion laws, with 14 states pending legislation. Most concussions are managed by primary care physicians, ie, family practice trained sports medicine physicians and pediatricians. Symptoms are usually short lived and do not require treatment. The one exception is headache, which is usually present from onset and is often the last symptom to resolve. Headache is the most common reason for referral to a specialist, and therefore it is imperative that the headache specialist have at least a basic understanding of all aspects of sports concussion as they are likely going to be called upon to evaluate these athletes, especially the more refractory cases.

    The purpose of this study was to assess role characteristics of clinical nurse specialists (CNSs) with prescriptive authority in Oregon 10 years after passage of Senate Bill 460. Factors examined included role preparation and mentorship, use and maintenance of authority, prescribing benefits and barriers, and types of drugs/nondrugs prescribed. This study was a descriptive survey using both quantitative and qualitative analysis. The sample was obtained from a list provided on June 13, 2014, by the Oregon State Board of Nursing of all CNSs in Oregon who had ever been granted prescriptive authority (n = 40). Twenty-nine with active authority, 7 with expired authority, and 4 with inactive status were sampled. E-mail distribution with Qualtrics software was released on June 27, 2014. Reminder e-mails were sent at 1 and 2 weeks. Of the 38 e-mails successfully delivered, 23 responses were received for a total response rate of 60%. Clinical nurse specialists successfully maintained their authority in Oregon and felt well prepared for their role. Their prescribing mentorship included nurse and nonnurse prescribers. They were most likely to have ever prescribed psychiatric, noncontrolled analgesics and durable medical equipment. They most frequently prescribed nutrition/electrolytes/fluids, durable medical equipment, and controlled analgesics. Lapse in authority was attributed to constraints regarding certification or credentialing in the role. Clinical nurse specialists uniformly expressed benefits from prescriptive authority. There were no differences in perceptions of preparation based on type of mentorship or educational modality for completion of prescribing requirements. There were systems barriers including lack of employer and colleague support to use of authority. Durable medical equipment authority is important to the CNS role. Clinical nurse specialists valued and maintained their prescriptive authority despite barriers. Further research is recommended to support

  14. The opinions of Finnish specialist physicians on social security system

    Directory of Open Access Journals (Sweden)

    2008-03-01

    Full Text Available

    Background: We can argue that opinions are considered to be part of the physician’s professional identity. Professional identity has been considered a result of learning. After graduation physicians usually continue to study to gain a specialisation, and we can assume that this process affects their opinions because every specialty has its own “cultural climate”. Also, specialists have different views towards the welfare state because, for example, of the fact that they work with different types of population groups.

    Aim of the study: In this article we will describe how specialists feel about the current level of social security in Finland.

    Methods: The empirical analysis in our study is based on postal survey. The 2000 working age physicians’ random survey sample was picked from the register of the Finnish Medical Association (n=1092, response rate 54,6 %. The whole questionnaire included questions dealing with social security, health policy and health care system. The data was analysed using means and multinomial logistic regression analysis.

    Results: This study shows that surgeons and radiologists are the most critical of social security. These groups often think that social security is excessive. In contrast, psychiatrists show a stronger tendency to support social security. All in all, Finnish specialists are more critical of the social security system than are nonspecialised physicians.

    Conclusions: There are many similarities between Nordic countries when we look at the historical role of medical profession. We can also assume that specialist physicians' opinions on social security are quite similar compared to those of other Nordic countries.

    Orthodontics is the most widely practised form of specialist dentistry in New Zealand. To date, no known qualitative research has been published examining the work-life balance of practitioners. The aim of this study was to investigate the working lives and work-life balance of NZ orthodontists in order to generate an understanding of the reality of orthodontic specialist practice and its effects on orthodontists' professional and personal lives. Semi-structured interviews were conducted involving 19 practising orthodontists (four females, 15 males; mean age 50 years) from throughout New Zealand and selected for maximum variation in the sample. Transcribed interviews were analysed for themes using an applied grounded theory approach. A core category of 'practising orthodontist' was derived, and related themes were grouped under the sub-categories of: (a) NZ orthodontic specialist practice; (b) NZ specialist orthodontists; and (c) Work-life balance. The present paper reports on the final sub-category. Themes emerging from the work-life sub-category were further divided into two sub-themes of 'work' and 'life'. Themes in the 'work' subgroup included time off, injuries and illness, regrets, personality traits, job stress and criticism, establishing a practice, peer support and contact, and success in orthodontics. Themes in the 'life' sub-group were personal development, family life, life balance and interests outside work, and financial security. This was the first qualitative investigation of the orthodontic profession in New Zealand. The findings provided a valuable insight into the working lives of New Zealand orthodontists and effects on their day-today lives. It will be revealing and interesting to observe how the modernisation of orthodontic practice will affect the work-life balance of New Zealand orthodontists in the future.

    2011-01-01

    This article discusses a practical, evidence-based approach to the diagnosis and management of liver cirrhosis by focusing on etiology, severity, presence of complications, and potential home-managed treatments. Relevant literature from 1985 to 2010 (PubMed) was reviewed. The search criteria were peer-reviewed full papers published in English using the following MESH headings alone or in combination: "ascites", "liver fibrosis","cirrhosis", "chronic hepatitis", "chronic liver disease","decompensated cirrhosis", "hepatic encephalopathy","hypertransaminasemia", "liver transplantation" and "portal hypertension". Forty-nine papers were selected based on the highest quality of evidence for each section and type (original, randomized controlled trial, guideline, and review article), with respect to specialist setting (Gastroenterology,Hepatology, and Internal Medicine) and primary care. Liver cirrhosis from any cause represents an emerging health issue due to the increasing prevalence of the disease and its complications worldwide. Primary care physicians play a key role in early identification of risk factors, in the management of patients for improving quality and length of life, and for preventing complications.Specialists, by contrast, should guide specific treatments, especially in the case of complications and for selecting patient candidates for liver transplantation. An integrated approach between specialists and primary care physicians is essential for providing better outcomes and appropriate home care for patients with liver cirrhosis.

  18. Caring for cancer patients on non-specialist wards.

    Gill, Finola

    2012-02-01

    As cancer is the leading cause of death worldwide, every nurse will be required to care for patients with the condition at some point in his\\/her career. However, non-specialized oncology nurses are often ill-prepared to nurse patients suffering from cancer. This literature review aims to provide an overview of current trends and developments in cancer care nursing in an attempt to identify the range of previous research pertaining to caring for patients with cancer on non-specialist wards. The review finds that non-specialized cancer nurses report a lack of education and training with regard to cancer care and cancer treatments, which acts as a barrier to providing quality nursing care. Emotional and communication issues with patients and their families can also cause non-specialist nurses significant distress. International research has shown that specialist oncology nurses make a considerable difference to physical and psychosocial patient care. It is therefore paramount that non-speciality nurses\\' educational needs are met to develop clinical competence and to provide supportive holistic care for both patients and their families.

  19. What are the roles of clinical nurses and midwife specialists?

    Science.gov (United States)

    Wickham, Sheelagh

    Research shows the increasing part the Clinical Nurse Specialist (CNS) plays in healthcare today. But what does a CNS actually do in their day-to day-work? This study, set in the Republic of Ireland, aimed to explore the CNS and clinical midwife specialist (CMS) roles in practice. Quantitative methodology was used to explore the roles and activities of the CNS and CMS. Following ethics approval, a valid and reliable questionnaire was circulated to the total population of CNS/CMS in Ireland. The data were analysed using SPSS. This study articulates the individual role elements and activity level. The findings show the CNS/CMS to be active in the roles of researcher, educator, communicator, change agent, leader and clinical specialist, but the level of activity varies between different roles and individual role elements. The CNS/CMS is seen as a valuable resource in health care today and has potential to have a positive effect on patient care. The majority of CNS/CMSs are active in varying roles but the analysis shows lesser activity in some areas, such as research. The findings merit further study on role activity and possible variables that influence role activity.

  1. Differentiating between a consultant nurse and a clinical nurse specialist.

    Science.gov (United States)

    Maylor, Miles

    With the introduction of nurse consultants, and regulation of the use of the designation 'specialist nurse', experienced practitioners such as clinical nurse specialists have seen their position eroded. Nurse consultants are a new NHS-employment category, and are expected to be at the top rank of the profession both in status and in salary. However, this article argues that nurses at various levels have the same core functions, and that these do not differ for nurse consultants. Distinguishing between practitioners that might have the same job description could be better done by measuring outcomes. More care needs to be taken over the use of words such as 'expert', which is used differently in different contexts, and it is suggested that competencies be developed by which to measure the effects of expertise. Although nurse consultant appointments are often driven by various political directives and they are employed to meet local and national priorities, difficult issues need to be faced. First, if nurse consultant jobs are the top of the clinical career ladder, will clinical nurse specialists (CNSs) need to accept a lower rung on it? Further, perhaps the title CNS should become obsolete or be regulated? Can CNSs claim parity of pay using the 'Agenda for Change' framework?

  2. From Humanizing the Educational Process to Professionally Mobile Specialists Training

    Directory of Open Access Journals (Sweden)

    T. A. Fugelova

    2012-01-01

    Full Text Available Training professional mobile specialists capable of responding flexibly to dynamic changes in society is considered to be the most important issue of the modern educational system. The paper justifies the idea that technical universities should take responsibility for solving this problem by means of humanization of technical education, which implies reconsidering its values and general notions. For overcoming the technocratic trends, the author recommends to cultivate the value of professionalism in the humanization context.Professionalism is defined by using the «professional service» idea as a «purpose acknowledgment, supertask, even a mission». The main components of the above attitude lie in finding the harmony with the world and its basic values. Therefore, technical universities face the challenge of training people of intelligence with a high moral and business responsibility. The basic value of such a person is regarded as «dedication to the cause» - the constant desire to improve the world and leave behind them- selves something of value to society. For training such specialists, the educational process should provide teachers dialogue and collaboration with students to facilitate the process of self-determination and self-development of the prospective specialists

    2009-01-01

    Several concurrent circumstances have created an impression through the media of a presumed lack of specialists in Spain, which has one of the highest densities of doctors per population in the world: simultaneous creation of jobs in many newly built hospitals; accepting garbage contracts (for months, half/thirds of days, shifts) in relevant hospitals rather than moving to unattractive positions; full dedication to the field of public or private healthcare rather than matching them; bad public healthcare working conditions (low wages, excessive healthcare pressure, lack of respect from the public and from healthcare managers, shifts, scarce professional promotion, difficult family reunification); decreased mobility due to insulation of the markets as a result of decentralization of healthcare by regions. There is no shortage of specialists in otolaryngology, but instead there are sporadic inequalities in their geographical distribution. The current number of positions as training doctors offered annually is higher at the moment than the demand of the Spanish society, for specialists who have adapted smoothly to the requirements of the new medical practice: clinical management, care quality, technology-based efficiency, evidence-based medicine. The modification of working conditions through higher flexibility in the working models and an increase of salaries based on activity and quality will show that the otolaryngology workforce which is generated with the current offer can assume the present and future demand. A high quality of specialized otolaryngology training is the substrate to be improved, so that future otolaryngology specialists will be able to face health challenges without unduly increasing their number.

    2009-12-01

    We used DNA microarrays to measure transcription and iTRAQ 2D liquid chromatography-mass spectrometry/mass spectrometry (a mass-tag labeling proteomic technique) to measure protein expression in 14 strains of Escherichia coli adapted for hundreds of generations to growth-limiting concentrations of either lactulose, methylgalactoside, or a 72:28 mixture of the two. The two ancestors, TD2 and TD10, differ only in their lac operons and have similar transcription and protein expression profiles. Changes in transcription and protein expression are observed at 30-250 genes depending on the evolved strain. Lactulose specialists carry duplications of the lac operon and show increased transcription and translation at lac. Methylgalactoside specialists are galS(-) and so constitutively transcribe and translate mgl, which encodes a transporter of methylgalactoside. However, there are two strains that carry lac duplications, are galS(-), and show increased transcription and translation at both operons. One is a generalist, the other a lactulose specialist. The generalist fails to sweep to fixation because its lac(+), galS(+) competitor expresses the csg adhesin and sticks to the chemostat wall, thereby preventing complete washout. Transcription and translation are sometimes decoupled. Lactulose-adapted strains show increased protein expression at fru, a fructose transporter, without evidence of increased transcription. This suggests that fructose, produced by the action of beta-galactosidase on lactulose, may leach from cells before being recouped. Reduced expression, at "late" flagella genes and the constitutive gat operon, is an adaptation to starvation. A comparison with two other long-term evolution experiments suggests that certain aspects of adaptation are predictable, some are characteristic of an experimental system, whereas others seem erratic.

    KENNEDY SPACE CENTER, FLA. -- STS-84 Mission Specialist Carlos I. Noriega prepares to enter the Space Shuttle Atlantis at Launch Pad 39A with help from white room closeout crew members. The fourth Shuttle mission of 1997 will be the sixth docking of the Space Shuttle with the Russian Space Station Mir. The commander is Charles J. Precourt. The pilot is Eileen Marie Collins. The five mission specialists are C. Michael Foale, Carlos I. Noriega, Edward Tsang Lu, Jean-Francois Clervoy of the European Space Agency and Elena V. Kondakova of the Russian Space Agency. The planned nine-day mission will include the exchange of Foale for U.S. astronaut and Mir 23 crew member Jerry M. Linenger, who has been on Mir since Jan. 15. Linenger transferred to Mir during the last docking mission, STS-81; he will return to Earth on Atlantis. Foale is slated to remain on Mir for about four months until he is replaced in September by STS-86 Mission Specialist Wendy B. Lawrence. During the five days Atlantis is scheduled to be docked with the Mir, the STS-84 crew and the Mir 23 crew, including two Russian cosmonauts, Commander Vasily Tsibliev and Flight Engineer Alexander Lazutkin, will participate in joint experiments. The STS-84 mission also will involve the transfer of more than 7,300 pounds of water, logistics and science equipment to and from the Mir. Atlantis is carrying a nearly 300-pound oxygen generator to replace one of two Mir units which have experienced malfunctions. The oxygen it generates is used for breathing by the Mir crew.

    Coastal marshes are one of the world's most productive ecosystems. Consequently, they have been heavily used by humans for centuries, resulting in ecosystem loss. Direct human modifications such as road crossings and ditches and climatic stressors such as sea-level rise and extreme storm events have the potential to further degrade the quantity and quality of marsh along coastlines. We used an 18-year marsh-bird database to generate population trends for 5 avian species (Rallus crepitans, Tringa semipalmata semipalmata, Ammodramus nelsonii subvirgatus, Ammodramus caudacutus, and Ammodramus maritimus) that breed almost exclusively in tidal marshes, and are potentially vulnerable to marsh degradation and loss as a result of anthropogenic change. We generated community and species trends across 3 spatial scales and explored possible drivers of the changes we observed, including marsh ditching, tidal restriction through road crossings, local rates of sea-level rise, and potential for extreme flooding events. The specialist community showed negative trends in tidally restricted marshes (-2.4% annually from 1998 to 2012) but was stable in unrestricted marshes across the same period. At the species level, we found negative population trends in 3 of the 5 specialist species, ranging from -4.2% to 9.0% annually. We suggest that tidal restriction may accelerate degradation of tidal marsh resilience to sea-level rise by limiting sediment supply necessary for marsh accretion, resulting in specialist habitat loss in tidally restricted marshes. Based on our findings, we predict a collapse of the global population of Saltmarsh Sparrows (A. caudacutus) within the next 50 years and suggest that immediate conservation action is needed to prevent extinction of this species. We also suggest mitigation actions to restore sediment supply to coastal marshes to help sustain this ecosystem into the future.

    2015-01-01

    The Space Communications and Navigation (SCAN) Testbed was a Software Defined Radio (SDR)-based payload launched to the International Space Station (ISS) in July of 2012. The purpose of the SCAN Testbed payload was to investigate the applicability of SDRs to NASA space missions in an operational space environment, which means that a proper model for system performance in said operational space environment is a necessary condition. The SCAN Testbed has line-of-sight connections to various ground stations with its S-Band Earth-facing Near-Earth Network Low Gain Antenna (NEN-LGA). Any previous efforts to characterize the NEN-LGA proved difficult, therefore, the NASA Glenn Research Center built its own S-Band ground station, which became operational in 2015, and has been successfully used to characterize the NEN-LGAs in-situ pattern measurements. This methodology allows for a more realistic characterization of the antenna performance, where the pattern oscillation induced by the complex ISS ground plane, as well as shadowing effects due to ISS structural blockage are included into the final performance model. This paper describes the challenges of characterizing an antenna pattern in this environment. It will also discuss the data processing, present the final antenna pattern measurements and derived model, as well as discuss various lessons learned.

Any previous efforts to characterize the NEN-LGA proved difficult, therefore, the NASA Glenn Research Center built its own S-Band ground station, which became operational in 2015, and has been used successfully to characterize the NEN-LGA's in-situ pattern measurements. This methodology allows for a more realistic characterization of the antenna performance, where the pattern oscillation induced by the complex ISS ground plane, as well as shadowing effects due to ISS structural blockage are included into the final performance model. This paper describes the challenges of characterizing an antenna pattern in this environment. It will also discuss the data processing, present the final antenna pattern measurements and derived model, as well as discuss various lessons learned

  1. What Proportion of Terminally Ill and Dying People Require Specialist Palliative Care Services?

    Directory of Open Access Journals (Sweden)

    Donna M. Wilson

    2014-01-01

    Full Text Available Currently, around 55 million people die each year worldwide. That number is expected to increase rapidly with accelerating population aging. Despite growth in the number of palliative care specialists and specialist services in most countries, the prospect of an increasing number of terminally ill and dying persons is daunting. This paper attempts to answer the question: what proportion of terminally ill and dying persons require specialist palliative care services? To address this question and highlight which persons require specialist palliative care, the current state of access to specialist palliative care services and specialists in Canada and other countries is highlighted, along with available evidence-based information on specialist services utilization and the care needs of terminally ill and dying persons. Current evidence and information gaps reveal that this question cannot be answered now, but it should be answered in advance of a crisis of unmet end-of-life care needs with the rising death toll.

    This report consists of the Proceedings of the Specialists' Meeting on High Energy Nuclear Data. The meeting was held on October 3-4, 1991, at the Tokai Research Establishment, Japan Atomic Energy Research Institute with the participation of forty-odd specialists, who were the evaluators, theorists, experimentalists, and users of high energy nuclear data including the members of Japanese Nuclear Data Committee. The need of the nuclear data in the high energy region up to a few GeV was stressed in the meeting for many applications, such as spallation neutron sources for radioactive waste treatment, accelerator shielding design, medical isotope production, radiation therapy, the effects of space radiation on astronauts and their equipment, and the cosmic history of meteorites and other galactic substances. Although the neutron nuclear data below 20 MeV have been well evaluated for fission and fusion reactor applications, the nuclear data in the high energy region have never been prepared in Japan. With the view of producing an evaluated high energy nuclear data file, theoretical models and codes, available and necessary measurements, needs of nuclear data, and various applications were reviewed and discussed. The consensus, that the wide collaboration was necessary to produce the evaluated file and should be established, has been obtained.

    In the training process, there is a tension between the work life and home life of trainees. This study explored both the personal impact and the opportunity costs of training from the Specialist Paediatric Registrar (SPR) perspective. The survey explored 1) career progression2) perceived functional effectiveness at work 3) psychological impact of hospital based training and 4) the personal and social cost of training. Fifty-three (71%) SPRs responded of whom 47 (89%)were married or in long term relationships. Seventy-five percent of trainees had a definite career plan with 86% intending to undertake fellowship training. Seventy percent believed they were efficient time managers but 53% had difficulty in making time for academic pursuits and fifty percent experienced negative feelings, which lingered after work and interfered with their relationships at home. Seventy-four percent stated training was undertaken at significant personal cost with only 21% achieving a very satisfactory work\\/life balance. To address these difficulties trainee wellbeing should be addressed at the Basic Specialist Training (BST) level and the career path clearly explained outlining the challenges that are likely to be encountered.

    Healthcare professional engagement is increasing. This study aims to identify levels of adoption and engagement of several social media platforms by a large international cohort of hernia surgery specialists. Hernia specialists attending the 38th International Congress of the European Hernia Society were identified. A manual search was then performed on Twitter, ResearchGate, and LinkedIn to identify those who had named accounts. Where accounts were identified, data on markers of utilisation were assessed. 759 surgeons (88.5% male) from 57 countries were identified. 334 surgeons (44%) engaged with a social media platform. 39 (5.1%) had Twitter accounts, 189 (24.9%) had ResearchGate accounts and 265 (34.9%) had LinkedIn accounts. 137 surgeons (18.1%) had accounts on 2 or more social media platforms. There was no gender association with social media account ownership (p > 0.05). Engagement in one social media platform was associated with increased engagement and utilisation on other platforms; LinkedIn users were more likely to have Twitter accounts (p social media amongst Hernia surgeons is similar to other surgical specialities. Geographical variation in SM engagement is seen. Engagement with one SM platform is associated with presence on multiple platforms.

    2017-01-01

    Nectar yeasts are common inhabitants of insect-pollinated flowers but factors determining their distribution are not well understood. We studied the influence of host identity, environmental factors related to pollution/urbanization, and the distance to a target beehive on local distribution of nectar yeasts within Robinia pseudoacacia L. and Tilia tomentosa Moench in Berlin, Germany. Nectar samples of six individuals per species were collected at seven sites in a 2 km radius from each target beehive and plated on YM-Agar to visualise the different morphotypes, which were then identified by sequencing a section of the 26S rDNA gene. Multivariate linear models were used to analyze the effects of all investigated factors on yeast occurrence per tree. Yeast distribution was mainly driven by host identity. The influence of the environmental factors (NO2, height of construction, soil sealing) strongly depended on the radius around the tree, similar to the distance of the sampled beehive. Incidence of specialist nectar-borne yeast species decreased with increasing pollution/urbanization index. Given that specialist yeast species gave way to generalist yeasts that have a reduced dependency on pollinators for between-flower dispersal, our results indicate that increased urbanization may restrict the movement of nectar-specialized yeasts, via limitations of pollinator foraging behavior.

    2008-03-01

    Full Text Available Abstract Background Specialist nurses may play an important role in helping to improve the experiences of patients with prostate cancer, however there is concern that the specialist nurse role is under threat in the UK due to financial pressures in the NHS. This study explored the role and value of specialist nurses in prostate cancer care via a survey and patient interviews. Methods This paper reports findings from two studies. A survey of patients from three hospitals across the UK (289/481, 60%, investigated whether patients who saw a specialist nurse had different experiences of information provision and involvement in decision-making, to those who did not. Qualitative interviews were also carried out with 35 men recently tested or treated for prostate cancer, recruited from two hospitals in the UK. Interviews explored patients' views on the role and value of the specialist nurse. Results Survey findings indicated that patients who saw a specialist nurse had more positive experiences of receiving written information about tests and treatment, and about sources of advice and support, and were more likely to say they made the treatment decision themselves. In interviews, patients described specialist nurse input in their care in terms of providing information and support immediately post-diagnosis, as well as being involved in ongoing care. Two key aspects of the specialist nurse role were seen as unique: their availability to the patient, and their ability to liaise between the patient and the medical system. Conclusion This study indicates the unique role that specialist nurses play in the experience of patients with prostate cancer, and highlights the importance of maintaining specialist nurse roles in prostate cancer care.

  13. Liquefaction, flow, and associated ground failure

    Science.gov (United States)

    Youd, T. Leslie

    1973-01-01

    Ambiguities in the use of the term liquefaction and in defining the relation between liquefaction and ground failure have led to encumbered communication between workers in various fields and between specialists in the same field, and the possibility that evaluations of liquefaction potential could be misinterpreted or misapplied. Explicit definitions of liquefaction and related concepts are proposed herein. These definitions, based on observed laboratory behavior, are then used to clarify the relation between liquefaction and ground failure. Soil liquefaction is defined as the transformation of a granular material from a solid into a liquefied state as a consequence of increased pore-water pressures. This definition avoids confusion between liquefaction and possible flow-failure conditions after liquefaction. Flow-failure conditions are divided into two types: (1) unlimited flow if pore-pressure reductions caused by dilatancy during flow deformation are not sufficient to solidify the material and thus arrest flow, and (2) limited flow if they are sufficient to solidify the material after a finite deformation. After liquefaction in the field, unlimited flow commonly leads to flow landslides, whereas limited flow leads at most to lateral-spreading landslides. Quick-condition failures such as loss of bearing capacity form a third type of ground failure associated with liquefaction.

    Wang, Shou-Yu; Windsor, Carol; Yates, Patsy

    2012-02-01

    Grounded theory, first developed by Glaser and Strauss in the 1960s, was introduced into nursing education as a distinct research methodology in the 1970s. The theory is grounded in a critique of the dominant contemporary approach to social inquiry, which imposed "enduring" theoretical propositions onto study data. Rather than starting from a set theoretical framework, grounded theory relies on researchers distinguishing meaningful constructs from generated data and then identifying an appropriate theory. Grounded theory is thus particularly useful in investigating complex issues and behaviours not previously addressed and concepts and relationships in particular populations or places that are still undeveloped or weakly connected. Grounded theory data analysis processes include open, axial and selective coding levels. The purpose of this article was to explore the grounded theory research process and provide an initial understanding of this methodology.

    Through a combination of experimentation and calculation the components of a novel room temperature dry load were successfully fabricated. These components included lossy ceramic cylinders of various lengths, thicknesses, and percent of silicon carbide (SiC). The cylinders were then assembled into stainless steel compression rings by differential heating of the parts and a special fixture. Post machining of this assembly provided a means for a final weld. The ring assemblies were then measured for S-parameters, individually and in pairs using a low-cost TE10 rectangular to TE01 circular waveguide adapter specially designed to be part of the final load assembly. Matched pairs of rings were measured for assembly into the final load and a sliding short designed and fabricated to assist in determining the desired short location in the final assembly. The plan for the project was for Muons, Inc. to produce prototype loads for long-term testing at SLAC. The STTR funds for SLAC were to upgrade and operate their test station to ensure that the loads would satisfy their requirements. Phase III was to be the sale to SLAC of loads that Muons, Inc. would manufacture. However, an alternate solution that involved a rebuild of the old loads, reduced SLAC budget projections, and a relaxed time for the replacement of all loads meant that in-house labor will be used to do the upgrade without the need for the loads developed in this project. Consequently, the project was terminated before the long term testing was initiated. However, SLAC can use the upgraded test stand to compare the long-term performance of the ones produced in this project with their rebuilt loads when they are available.

    Treister, N W

    1997-01-01

    Marketing means more than just communicating or advertising to potential patients; marketing means identifying your customers and working to meet or exceed their expectations. There are five key areas of a marketing plan: (1) Establish the foundation, beginning with your mission statement; (2) Assess your marketing environment by internal and external research; (3) Target your efforts, looking at image and perception; (4) Develop your particular mix of product, price, place of distribution, and promotion; and (5) implement and evaluate your marketing process. This article discusses the importance of a marketing plan for the medical specialist and highlights the features unique to a practice working in a system of capitated reimbursement. Applying these principles will help to demonstrate added value, protect the fundamental role of the patient-physician relationship, ensure that our efforts are aligned with professional missions and goals, and ultimately increase profitability and professional success.

    This study investigated the injuries sustained by an Australian specialist police division. Injury records spanning four-years were analyzed. The role being performed when the injury occurred, injury cause, body part injured, and injury-related costs were quantified. The percentage of personnel injured multiple times was documented. One hundred and thirty eight personnel reported injuries, 58 of these on multiple occasions. This resulted in 229 injuries and 76 claims being raised. Half of the injuries occurred during operational policing tasks, however training activities accounted for >30% of injuries. The most common injury was strain/sprain, and upper body injuries were 2.5-times more common than lower-body or torso injuries. 1107 shifts were lost, and injuries cost the organization $487,159 (Australian Dollars) over the four-year period. The injury costs (both financial and in manpower) may prompt policy makers to review the current training and post-injury rehabilitation protocols.

    2017-02-01

    The world of medicine is becoming from year to year more complex. This necessitates efficient learning processes, which incorporate the principles of adult education but with unchanged periods of further education. The subject matter must be processed, organized, visualized, networked and comprehended. The learning process should be voluntary and self-driven with the aim of learning the profession and becoming an expert in a specialist field. Learning is an individual process. Despite this, the constantly cited learning styles are nowadays more controversial. An important factor is a healthy mixture of blended learning methods, which also use new technical possibilities. These include a multitude of e‑learning options and simulations, which partly enable situative learning in a "shielded" environment. An exemplary role model of the teacher and feedback for the person in training also remain core and sustainable aspects in medical further education.

    Brown, Rachel; Jubb, Mags

    2016-11-08

    Healthcare play specialists (HPSs) provide therapeutic play programmes for children in healthcare settings. Each HPS student must have a mentor in practice, but most HPSs have received no formal training for their role. This article explores mentoring in the HPS service at Guy's and St Thomas' NHS Foundation Trust. A study day for HPSs was arranged to share best practice and discuss the challenges of mentoring students. Stronger links were built between the higher education institute that delivers the training to HPS students and the trust, and the HPSs were provided with a deeper understanding of what was required of them in their mentoring role. HPSs highlighted the importance of a yearly update on mentoring students.

    Vollman, K M; Stewart, K H

    1996-05-01

    The clinical nurse specialist (CNS) is in an excellent position to lead and design the necessary changes required in acute, chronic, and home care settings to meet the economic and legislative agendas to reshape health-care delivery. In this article, the authors, through the use of examples, outline key quality characteristics of a successful unit-based, system-focused model of CNS practice. Clearly, the benefits obtained from the outcomes of a traditional CNS role make a significant contribution to the profession of nursing and to the public. Without the CNS role, the opportunity for system change and the development and nurturing of the front-line health-care worker may be lost.

  7. Advance directives: the clinical nurse specialist as a change agent.

    Meehan, Karen Anne

    2009-01-01

    The purpose of this article is to describe the impact the clinical nurse specialist (CNS) has on the advance directive process within the cardiac surgery patient population. As a change agent, the CNS needs to be able to increase the number of advance directives obtained and increase the provision of dignified, self-directed, quality patient care. With requirements from The Joint Commission and the Patient Self-determination Act, the change in process must take place to ensure that healthcare professionals are doing all they can do to carry out a patient's wishes. The 6-Source Influencer Model is applied to a case study to illustrate the role of the CNS as a change agent. Following this model, the CNS can facilitate lasting institutional change in the advance directive process. Based on the example, it is possible that a CNS can act as a change agent for other patient populations within the healthcare setting.

  8. Learning Abilities and Disabilities: Generalist Genes, Specialist Environments.

    Kovas, Yulia; Plomin, Robert

    2007-10-01

    Twin studies comparing identical and fraternal twins consistently show substantial genetic influence on individual differences in learning abilities such as reading and mathematics, as well as in other cognitive abilities such as spatial ability and memory. Multivariate genetic research has shown that the same set of genes is largely responsible for genetic influence on these diverse cognitive areas. We call these "generalist genes." What differentiates these abilities is largely the environment, especially nonshared environments that make children growing up in the same family different from one another. These multivariate genetic findings of generalist genes and specialist environments have far-reaching implications for diagnosis and treatment of learning disabilities and for understanding the brain mechanisms that mediate these effects.

    We do not know what factors influence residents' perceived satisfaction during their training. The aim of this study was to analyze the satisfaction of specialists with their training and its associated factors. This was a cross-sectional study using self-completion surveys of residents in training at the Clinic Hospital San Carlos for the courses conducted in 2006, 2009, 2010 and 2012. The study's dependent variable was overall satisfaction with the training; the independent factors were demographic and occupational characteristics, variables related to healthcare, teaching and research activity. The total participation percentage was 83.7% (1,424/1,701), and the mean age was 28.4 years (SD, 3.2 years). The overall satisfaction percentage was 75.2%. The factors statistically associated with overall satisfaction in the multivariate analysis were the involvement of the teaching staff (tutors and assistants) in the training, greater satisfaction in medical versus surgical specialties, the year of residence, the facilities for completing the thesis, working less than 40 h a week, adequate time to perform daily tasks, appropriate number of department meetings and not having a previous specialty. the activities related to research and teaching are associated with the overall satisfaction of residents. The routine activity factors most closely associated with satisfaction were the time available and the work hours. More studies are necessary to understand the impact of resident satisfaction on care quality and in their activity as future specialists. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    2009-01-01

    To validate the 75 core National Association of Clinical Nurse Specialists' (NACNS) clinical nurse specialist (CNS) competencies among practicing CNSs. Specific aims were to (a) determine the extent to which 75 core CNS competencies were used in current CNS practice, (b) determine the importance of those competencies to practicing CNSs, and (c) identify gaps between CNS core competencies and role expectations in current practice. A survey design was used with both paper-and-pencil and online instruments. The survey included 150 items and three open-ended questions. A convenience sampling method was used, which targeted practicing CNSs. Respondents (N=505) were practicing CNSs who entered the field as RNs between 1956 and 2006. The survey had a high degree of internal consistency reliability (0.967%) between the subscales. The 75 NACNS core competencies were found to be useful and important for CNSs. A few gaps were identified between CNS core competencies and CNS role expectations in current practice. No one method for validating competencies will be satisfactory for all situations; however, the processes and methods used in this study were well suited to accomplish the goal of validating CNS core competencies. The process described here may be instructive to leaders of other national and international professional organizations interested in developing and evaluating competencies. Core competencies are useful and important to currently practicing CNSs. The CNS role is growing internationally. Core CNS competencies can be a framework for CNS role development, education, and practice. As described here, a competency validation survey is one way to assure that CNSs are meeting healthcare needs.

    The training period in neurophysiology is a substantial part of the Neurology Specialist Program in Spain. The National Neurology Committee (La Comisión Nacional de Neurología (CNN), which is the body reporting to the Ministries of Health and Education, must ensure compliance to the Program. During the first trimester of 2008, the CNN sent a questionnaire, in which there was a question asking about this training period, to each of the managers of the 69 teaching units accredited for neurology training in Spain, for them to answer. Of the 69 questionnaires issued, 49 were received completed, which was a response rate of 71%. The neurophysiology training period of the neurology specialist program in Spain was carried out in the same hospital in 44 teaching unit (90%): the remaining 5 sent their neurology trainees to 4 different hospitals. The Unit that carried out the neurophysiology training period was incorporated into the Neurology Department in 27 (55%) cases, and the formula was mixed in 3 (6%). A total of 69% of tutors were satisfied with the training, but was 90% in the hospitals where the unit was integrated into Neurology, and was 65% where this relationship did not exist. The neurologists in training were informed about EEG in 49% of education units, performed EMG/ENG 57%, and informed about evoked potentials in 35% after their training period. Although the level of satisfaction is high, the level of responsibility assumed by the neurologists in training during their rotation into neurophysiology does not appear to comply to the demands laid out in the training program, particularly in these units not integrated into Neurology Departments.

  17. Communication, concepts and grounding.

    Science.gov (United States)

    van der Velde, Frank

    2015-02-01

    This article discusses the relation between communication and conceptual grounding. In the brain, neurons, circuits and brain areas are involved in the representation of a concept, grounding it in perception and action. In terms of grounding we can distinguish between communication within the brain and communication between humans or between humans and machines. In the first form of communication, a concept is activated by sensory input. Due to grounding, the information provided by this communication is not just determined by the sensory input but also by the outgoing connection structure of the conceptual representation, which is based on previous experiences and actions. The second form of communication, that between humans or between humans and machines, is influenced by the first form. In particular, a more successful interpersonal communication might require forms of situated cognition and interaction in which the entire representations of grounded concepts are involved.

    Strong earthquake ground motion records are fundamental in engineering applications. Ground motion time series are used in response-history dynamic analysis of structural or geotechnical systems. In such analysis, the validity of predicted responses depends on the validity of the input excitations. Ground motion records are also used to develop ground motion prediction equations(GMPEs) for intensity measures such as spectral accelerations that are used in response-spectrum dynamic analysis. Despite the thousands of available strong ground motion records, there remains a shortage of records for large-magnitude earthquakes at short distances or in specific regions, as well as records that sample specific combinations of source, path, and site characteristics.

    Metz, P. D.

    The feasibility of ground coupling for various heat pump systems was investigated. Analytical heat flow models were developed to approximate design ground coupling devices for use in solar heat pump space conditioning systems. A digital computer program called GROCS (GRound Coupled Systems) was written to model 3-dimensional underground heat flow in order to simulate the behavior of ground coupling experiments and to provide performance predictions which have been compared to experimental results. GROCS also has been integrated with TRNSYS. Soil thermal property and ground coupling device experiments are described. Buried tanks, serpentine earth coils in various configurations, lengths and depths, and sealed vertical wells are being investigated. An earth coil used to heat a house without use of resistance heating is described.

    With the global decline of in situ snow measurements for hydrometeorological applications, there is an evolving need to find alternative ways to collect localized measurements of snow. The Snowtweets Project is an experiment aimed at providing a way for people interested in making snow measurements to quickly broadcast their measurements to the internet. The goal of the project is to encourage specialists and non-specialists alike to share simple snow depth measurements through widely available social networking sites. We are currently using the rapidly growing microblogging site Twitter (www.twitter.com) as a broadcasting vehicle to collect the snow depth measurements. Using 140 characters or less, users "tweet" their snow depth from their location through the Twitter website. This can be done from a computer or smartphone with internet access or through SMS messaging. The project has developed a Snowtweets web application that interrogates Twitter by parsing the 140 character string to obtain a geographic position and snow depth. GeoRSS and KML feeds are available to visualize the tweets in GoogleEarth or they can be viewed in our own visualiser, Snowbird. The emphasis is on achieving wide coverage to increase the number of microblogs. Furthermore, after some quality control filters, the project is able to combine the broadcast snow depths with traditional and objective satellite remote sensing-based observations or hydrologic model estimates. Our site, snowcore.uwaterloo.ca, was launched in July 2009 and is ready for the 2009-2010 northern hemisphere winter. We invite comments from experienced community participation projects to help improve our product.

    As an important electron source, Micro-Pulse electron Gun (MPG) which is qualified for producing high average current, short pulse, low emittance electron bunches steadily holds promise to use as an electron source of Coherent Smith-Purcell Radiation (CSPR), Free Electron Laser (FEL). The stable output of S-band MPG has been achieved in many labs. To establish reliable foundation for the future application of it, the propagation of picosecond electron bunch produced by MPG should be studied in detail. In this article, the MPG which was working on the rising stage of total effective Secondary Electron Yield (SEY) curve was introduced. The self-bunching mechanism was discussed in depth both in the multipacting amplifying state and the steady working state. The bunch length broadening induced by the longitudinal space-charge (SC) effects was investigated by different theoretical models in different regions. The 2D PIC codes MAGIC and beam dynamic codes TraceWin simulations were also performed in the propagation. The result shows an excellent agreement between the simulation and the theoretical analysis for bunch length evolution.

    2014-01-01

    The purpose of this article was to describe the history and leadership dimensions of the role of resuscitation process manager and provide specific examples of how this role is implemented at a Midwest medical center. In 1992, a medical center in the Midwest needed a nurse to manage resuscitation care. This role designation meant that this nurse became central to all quality improvement efforts in resuscitation care. The role expanded as clinical resuscitation guidelines were updated and as the medical center grew. The role became known as the critical care clinical nurse specialist as resuscitation process manager. This clinical care nurse specialist was called a manager, but she had no direct line authority, so she accomplished her objectives by forming a multitude of collaborative networks. Based on a framework by Finkelman, the manager role incorporated specific leadership abilities in quality improvement: (1) coordination of medical center-wide resuscitation, (2) use of interprofessional teams, (3) integration of evidence into practice, and (4) staff coaching to develop leadership. The manager coordinates resuscitation care with the goals of prevention of arrests if possible, efficient and effective implementation of resuscitation protocols, high quality of patient and family support during and after the resuscitation event, and creation or revision of resuscitation policies for in-hospital and for ambulatory care areas. The manager designs a comprehensive set of meaningful and measurable process and outcome indicators with input from interprofessional teams. The manager engages staff in learning, reflecting on care given, and using the evidence base for resuscitation care. Finally, the manager role is a balance between leading quality improvement efforts and coaching staff to implement and sustain these quality improvement initiatives. Revisions to clinical guidelines for resuscitation care since the 1990s have resulted in medical centers developing improved

    Radiotherapy practitioners may be best placed to undertake qualitative research within the context of cancer, due to specialist knowledge of radiation treatment and sensitivity to radiotherapy patient's needs. The grounded theory approach to data collection and analysis is a unique method of identifying a theory directly based on data collected within a clinical context. Research for radiotherapy practitioners is integral to role expansion within the government's directive for evidence-based practice. Due to the paucity of information on qualitative research undertaken by radiotherapy radiographers, this article aims to assess the potential impact of qualitative research on radiotherapy patient and service outcomes.

    Whitfield, J D; Biamonte, J D

    2012-01-01

    Designing and optimizing cost functions and energy landscapes is a problem encountered in many fields of science and engineering. These landscapes and cost functions can be embedded and annealed in experimentally controllable spin Hamiltonians. Using an approach based on group theory and symmetries, we examine the embedding of Boolean logic gates into the ground state subspace of such spin systems. We describe parameterized families of diagonal Hamiltonians and symmetry operations which preserve the ground state subspace encoding the truth tables of Boolean formulas. The ground state embeddings of adder circuits are used to illustrate how gates are combined and simplified using symmetry. Our work is relevant for experimental demonstrations of ground state embeddings found in both classical optimization as well as adiabatic quantum optimization.

    The purpose of this article was to describe a collaborative clinical nurse specialist (CNS) project to enhance the patient education provided by registered nurses across 7 medical nursing units in an acute care hospital. Electronic data reviews assisted the medical CNSs with identifying a deficit in using appropriate education plans and documentation of patient education. The interventions implemented included the creation of new patient education brochures, updating the electronic system to enhance nurses' ability to provide patient education materials and to simplify documentation, creating a video-on-demand education channel, and ensuring that patient education materials were easily accessible. Postassessment results showed that nurses' reported use of disease-specific education plan increased 33%. The staff's perception of the importance of documenting patient education provided also increased 9%. This project demonstrates CNSs' ability to design, develop, and implement a systematic and structured process to promote a consistent way for medical nurses to utilize the best disease-specific patient education resources. : With hospital stays being shorter and patients more acutely ill, partnering with the patients in learning how to manage their care as they transition from the hospital to home is key to help prevent hospital readmissions.

    Heart rhythm (HR) management is rapidly developing as a subspecialty within cardiology, and it is imperative to promote and ensure sufficient and homogeneous training and qualification amongst professionals in Europe. This has led the European Society of Cardiology, through the European Heart Rhythm Association (EHRA), to organize a European Core Curriculum for the HR specialist through the following: definition of the scope of the HR speciality (Syllabus), development of minimum standards and objectives for training in HR management (Curriculum), development of a model to certify HR professionals and teaching units (Accreditation), and development of a Registry for European HR accredited professionals and teaching units and its activity (Registries). The duration of the training period should be of a minimum of 2 years following general cardiology training. During this period, the trainee must develop the required knowledge, practical skills, behaviours, and attitudes to manage HR patients. The trainee must be involved in a minimum number of different procedures and achieve specified levels of competence. The training centre should be integrated within a full-service cardiology department. Assessment of the trainee and the training programmes should include reports by the training programme supervisor and the national society HR organizations, a logbook of procedures, written examinations, and assessment of professionalism. The EHRA presently requires the trainee to pass the EHRA accreditation exams (invasive EP and cardiac pacing and ICDs). Continuous learning and practice are required to maintain standards and practice and because substantial changes may occur in clinical practice or the health-care environment.

  16. [Specialist pharmacist training from the viewpoint of sports pharmacology].

    When athletes consult sports outpatient or orthopedic clinics it is possible to undergo drug treatment with the medical staff having prior knowledge of that patient being an athlete. However, if athletes seek any other diagnosis and treatment as an ordinary patient, the possibility of medical staff realizing the potential for imposing a doping issue on the athlete is extremely low. As a result, if the athlete fails to provide medical staff with information regarding anti-doping regulations when receiving clinical treatment, drug treatment administered as part of medical practices could be viewed as doping, resulting in the athlete being disciplined. In order to avoid this, pharmacist should participate in training in order to be able to provide information for anti-doping purposes. It is my personal opinion that knowledge regarding anti-doping is something that should be shared by all pharmacists, as pharmacists are educated in the fields of pharmacology and pharmacokinetics during the pharmacy education process, and sports pharmacology is a part of this. However, in order for pharmacists to understand sports pharmacology, it is necessary to provide education not only on the benefits and adverse effects of pharmaceutical products, but also on the concept of banned substances. It can be considered one of the pharmacist's duties to protect athletes who purchase drugs at a pharmacy or consult medical institutions as patients. With this, I would like to propose considering the potential for introducing sports pharmacology to pharmaceutical education, and specialist pharmacist training in the sports spectrum.

  17. An evaluation of teamwork within a specialist palliative care unit.

    2002-11-01

    This small-scale 10-month study evaluated teamworking within a specialist palliative care team. The study aims were to: collect, analyse and summarize information on how team members perceive teamworking; compare team members' perceptions after a teambuilding workshop; and to evaluate the longer term effect of this training on the team. A group of practitioners from a local Marie Curie Cancer Care Centre was selected and included members from all available disciplines. A piloted questionnaire was used to obtain qualitative and quantitative input. The team as a whole scored themselves above average on almost all counts. Following the teambuilding workshop significant improvement was seen in areas such as role appreciation and communication but not all improvements were long lasting. A perception of understaffing was noted as being one of the largest negative influences on teamwork whereas the setting and maintaining of agreed team objectives and having sufficient education opportunity were positive influences. Although teambuilding sessions appear to have the potential to produce the desired benefits, they should not be initiated at a time when staff already feel anxiety over their workload.

    This study evaluated three domains of job burnout (emotional exhaustion, depersonalization, and personal accomplishment) and factors associated with burnout in a national sample of peer specialists (PSs) employed at 138 Veterans Health Administration (VHA) health care systems in 49 states. Data were drawn from an observational study in which participants (N=152) completed online, self-report surveys about their mental health recovery, quality of life, and employment experiences at baseline, six months, and 12 months. Levels of burnout were analyzed at each time point, and regression analyses that controlled for baseline levels identified potential predictors of burnout (demographic, clinical, and employment characteristics) at six and 12 months. Compared with previously published burnout levels of other mental health workers in the VHA, PSs reported similar levels of emotional exhaustion, depersonalization, and personal accomplishment. At baseline, increased burnout was correlated with white race, fewer hours providing direct services, greater psychiatric symptoms, and lower self-efficacy. However, analyses did not reveal strong predictors of burnout scores at six or 12 months. In the first study to prospectively examine job burnout among PSs employed by the VHA, results illustrate the nuanced experience of burnout over a 12-month period and suggest the need for replication and further research on employment experiences of this emerging workforce.

  19. River Cetaceans and Habitat Change: Generalist Resilience or Specialist Vulnerability?

    Full Text Available River dolphins are among the world’s most threatened mammals, and indeed the baiji (Lipotes vexillifer, a species endemic to China's Yangtze River, is likely extinct. Exploitation for products such as meat, oil, and skins has been a lesser feature in the population histories of river dolphins compared to most large mammals. Habitat factors are therefore of particular interest and concern. In this paper we attempt to describe the population-level responses of river dolphins to habitat transformation. We find circumstantial but compelling evidence supporting the view that, at a local scale, river dolphins are opportunists (generalists capable of adapting to a wide range of habitat conditions while, at a river basin scale, they are more appropriately viewed as vulnerable specialists. The same evidence implies that the distributional responses of river dolphins to basinwide ecological change can be informative about their extinction risk, while their local behaviour patterns may provide important insights about critical ecological attributes. Empirical studies are needed on the ecology of river cetaceans, both to inform conservation efforts on behalf of these threatened animals and to help address broader concerns related to biodiversity conservation and the sustainability of human use in several of the world's largest river systems.

    2006-01-01

    AIM: To find out whether there are differences in attitudes about colorectal cancer (CRC) screening among gastrointestinal (GI) specialists and general practitioners (GPs) and which method is preferred in a national screening programMETHODS: Four hundred and twenty Dutch GI specialists in the Netherlands and 400 GPs in Amsterdam were questioned in 2004. Questions included demographics, affiliation, attitude towards screening both for the general population and themselves, methods of screening, family history and individual risk.RESULTS: Eighty-four percent of the GI specialists returned the questionnaire in comparison to 32% of the GPs (P < 0.001). Among the GI specialists, 92% favoured population screening whereas 51% of GPs supported population screening (P < 0.001). Of the GI specialists 95% planned to be screened themselves, while 30%of GPs intended to do so (P < 0.001). Regarding the general population, 72% of the GI specialists preferred colonoscopy as the screening method compared to 27% of the GPs (P < 0.001). The method preferred for personal screening was colonoscopy in 97% of the GI specialists, while 29% of the GPs favoured colonoscopy (P < 0.001).CONCLUSION: Screening for CRC is strongly supported by Dutch GI specialists and less by GPs. The major health issue is possibly misjudged by GPs. Since GPs play a crucial role in a successful national screening program, CRC awareness should be realized by increasing knowledge about the incidence and mortality, thus increasing awareness of the need for screening among GPs.

  2. Modeling fraud detection and the incorporation of forensic specialists in the audit process

    DEFF Research Database (Denmark)

    Sakalauskaite, Dominyka

    Financial statement audits are still comparatively poor in fraud detection. Forensic specialists can play a significant role in increasing audit quality. In this paper, based on prior academic research, I develop a model of fraud detection and the incorporation of forensic specialists in the audit...... process. The intention of the model is to identify the reasons why the audit is weak in fraud detection and to provide the analytical framework to assess whether the incorporation of forensic specialists can help to improve it. The results show that such specialists can potentially improve the fraud...... detection in the audit, but might also cause some negative implications. Overall, even though fraud detection is one of the main topics in research there are very few studies done on the subject of how auditors co-operate with forensic specialists. Thus, the paper concludes with suggestions for further...

  3. Personal view: randomized controlled trials in epilepsy specialist nursing: the seduction of content by form.

    Science.gov (United States)

    Brown, Stephen

    2002-04-01

    Research into the effectiveness of epilepsy specialist nursing needs to take into account a number of factors, which have not been adequately addressed in previous studies. Nursing outcome measures are different to medical ones and it is inappropriate to confuse these. Specialist nurses affect the whole culture of a service, and their impact on service quality may go beyond that of their individual patient contacts. Thus randomized studies within a service that already has specialist nurses may not give valid results. Some service users will benefit more from direct contact with a specialist nurse than others, and people who give informed consent to take part in randomized controlled trials might not be representative of those who would benefit most from specialist nurse access. The stampede for level one evidence risks failing to address the issues properly by overvaluing research process (form) against its appropriateness (content), yet there remain great opportunities for good quality research in this area.

    2006-12-01

    Full Text Available Abstract Background Collaboration between general practitioners (GPs and specialists has been the focus of many collaborative care projects during the past decade. Unfortunately, quite a number of these projects failed. This raises the question of what motivates medical specialists to initiate and continue participating with GPs in new collaborative care models. The following question is addressed in this study: What motivates medical specialists to initiate and sustain new models for collaborating with GPs? Methods We conducted semi-structured interviews with eighteen medical specialists in the province of Groningen, in the North of The Netherlands. The sampling criteria were age, gender, type of hospital in which they were practicing, and specialty. The interviews were recorded, fully transcribed, and analysed by three researchers working independently. The resulting motivational factors were grouped into categories. Results 'Teaching GPs' and 'regulating patient flow' (referrals appeared to dominate when the motivational factors were considered. In addition, specialists want to develop relationships with the GPs on a more personal level. Most specialists believe that there is not much they can learn from GPs. 'Lack of time', 'no financial compensation', and 'no support from colleagues' were considered to be the main concerns to establishing collaborative care practices. Additionally, projects were often experienced as too complex and time consuming whereas guidelines were experienced as too restrictive. Conclusion Specialists are particularly interested in collaborating because the GP is the gatekeeper for access to secondary health care resources. Specialists feel that they are able to teach the GPs something, but they do not feel that they have anything to learn from the GPs. With respect to professional expertise, therefore, specialists do not consider GPs as equals. Once personal relationships with the GPs have been established, an

    2009-01-01

    Full Text Available Background: Fine needle aspiration biopsy (FNAB is a simple, sensitive, quick and inexpensive method in which operator experience is essential for obtaining the best results. Methods: A descriptive study in which the aspiration biopsy cases of the Pathology and Cytopathology Service of the University Hospital of the UANL (2003-2005 were analyzed. These were divided into three study groups: Group 1, FNAB performed by a pathologist; Group 2, FNAB performed by specialists who are not pathologists, Group 3, FNAB guided by an imaging study with immediate evaluation by a pathologist. The samples were classified as adequate and inadequate for diagnosis, the organ, the size and characteristics of the lesions were taken into consideration. Results: A total of 1905 FNAB were included. In Group 1: 1347 were performed of which 1242 (92.2% were adequate and 105 (7.7% were inadequate. Of the 237 from Group 2, 178 were adequate (75.1% and 59 inadequate (24.8%; in Group 3 there were 321 of which 283 (88.1% were adequate and 38 (11.8% inadequate. A statistically significant difference was found between FNAB performed by Group 1 (p< 0.001 and the other groups. A multivariate analysis was done where the organ punctured, the study groups, the size and characteristics of the lesion by study group were compared, finding that the most important variable was the person who performed the procedure. Conclusion: The experience and training of the person performing the aspiration biopsy, as well as immediate evaluation of the material when it is guided, substantially reduces the number of inadequate samples, improving the sensitivity of the method as well as reducing the need for open biopsies to reach a diagnosis.

    2013-01-01

    Research on the correlation between personality and students' specialty choice is helpful in their career counselling process and in predicting the future distribution of the specialties in a country. This study is the first of its kind in the Arab world. The research questions were: (1) What is the influence of gender on the personality profiles of medical students? (2) What are the personality profiles of students categorized according to their preferred specialist choices? (3) What are the preferred career choices of students categorized according to the stage of their medical education? A cross-sectional study was performed at King Khalid University Medical School including 590 students during the academic year 2010-2011. A long version of the Zuckerman-Kuhlman personality questionnaire measuring five personality factors was used. Students were also asked for their specialty interests. Students were asked by means of a written questionnaire. Study response was 92.5%. Surgery was the single most popular specialty amongst both male and female students. Males had significantly higher scores on the 'impulsive sensation seeking' scale and students preferring a surgery specialty had the highest score on the 'impulsive sensation seeking', 'neuroticism-anxiety', 'aggression-hostility' and 'sociability' scales. Hospital-based, surgical and primary care specialties became more popular as students progressed through their undergraduate years. Different personality types have distinct preferences in medical students' choice of careers. Personality and specialty choice research can enhance career counselling of medical students and fresh graduates. This also has implications for predicting the specialty distribution of the future health careers.

    Workplace-based assessments should provide a reliable measure of trainee performance, but have met with mixed success. We proposed that using an entrustability scale, where supervisors scored trainees on the level of supervision required for the case would improve the utility of compulsory mini-clinical evaluation exercise (CEX) assessments in a large anaesthesia training program. We analysed mini-CEX scores from all Australian and New Zealand College of Anaesthetists trainees submitted to an online database over a 12-month period. Supervisors' scores were adjusted for the expected supervision requirement for the case for trainees at different stages of training. We used generalisability theory to determine score reliability. 7808 assessments were available for analysis. Supervision requirements decreased significantly (P  0.7) with a feasible number of assessments. Adjusting scores against the expected supervision requirement considerably improved reliability, with G > 0.8 achieved with only nine assessments. Three per cent of trainees generated average mini-CEX scores below the expected standard. Using an entrustment scoring system, where supervisors score trainees on the level of supervision required, mini-CEX scores demonstrated moderate reliability within a feasible number of assessments, and evidence of validity. When scores were adjusted against an expected standard, underperforming trainees could be identified, and reliability much improved. Taken together with other evidence on trainee ability, the mini-CEX is of sufficient reliability for inclusion in high stakes decisions on trainee progression towards independent specialist practice. © The Author 2017.

    Full Text Available Introduction: Quality of life (QOL of emergency medicine specialists can be effective in providing services to patients. The aim of the present study was evaluating the lifestyle of emergency medicine practitioners, understanding their problems, and addressing the solutions to enhance and improve their lifestyles, in teaching hospitals in Iran. Method: This descriptive cross-sectional study was conducted on emergency medicine physicians in 10 teaching hospitals of Iran in 2011. Emergency physicians with at least three years of experience who interested in the study, were enrolled in the project. All participants filled out the consent form and QOL questionnaires, then underwent physical examinations and some medical laboratory tests. Categorical variables were reported as percentages, while continuous variables expressed as means and standard deviations. p <0.05 was considered statistically significant. Results: Totally, 100 subjects participated in the study, of whom 48 were male. The mean and standard deviation of the physicians’ age were 38.7±5.1 years. 43% of physicians had an average QOL, while 37% good. 96% of studied physicians had a good condition regarding habitual history, while 93% of them had a poor condition in performing screening tests. Exercise program and personal health in individuals with normal BMI were correlated with higher levels of QOL. BMI was higher in 40-50 years old subjects than youngers. Hypertension was present in five cases (5%, hypercholesterolemia in six (6%, hypertriglyceridemia in six (6%, increased LDL in four (4%, low HDL in four (4%, and impaired FBS in 4 (4%. Conclusion: The findings showed that 63% of studied emergency physicians had an average level of QOL and other ones good. The majority of physicians had undesirable situation regarding the performance of screening tests.

  14. Geographic variation in resource use by specialist versus generalist butterflyfishes

    Lawton, Rebecca J.

    2011-11-14

    Localised patterns of resource use can be constrained by multiple factors. Comparison of resource use at multiple locations with differing resource availability can allow fundamental specialists to be distinguished from species that simply feed predominantly on prey types that are locally abundant. This study investigates geographic variation in the feeding ecology of coral-feeding butterflyfishes to examine whether patterns of resource use and levels of dietary specialisation vary among distinct locations, corresponding with changes in resource availability. Our specific aims were to investigate whether the dietary niche breadth of four butterflyfishes varies among five geographically separated locations and assess whether each species utilises similar resources in each location. Resource availability and dietary composition of four butterflyfishes were quantified at three sites across each of five geographic locations throughout the Pacific. Niche breadth, niche overlap, and resource selection functions were calculated for each species at each site and compared among locations. Availability of dietary resources varied significantly among locations and sites. Chaetodon vagabundus, C. citrinellus and C. lunulatus had low levels of dietary specialisation and used different resources in each location. Chaetodon trifascialis had high levels of dietary specialisation and used the same few resources in each location. Our results indicate that relative levels of dietary specialisation among different butterflyfishes do hold at larger spatial scales, however, geographical variation in the dietary composition of all butterflyfishes indicates that prey availability has a fundamental influence on dietary composition. Highly specialised species such as C. trifascialis will be highly vulnerable to coral loss as they appear to be largely inflexible in their dietary composition. However, the increased feeding plasticity observed here for C. trifascialis suggests this species may

    One of the first requisites for the intelligent planning of utilization and control of water and for the administration of laws relating to its use is data on the quantity, quality, and mode of occurrence of the available supplies. The collection, evaluation and interpretation, and publication of such data are among the primary functions of the U.S. Geological Survey. Since 1895 the Congress has made appropriations to the Survey for investigation of the water resources of the Nation. In 1929 the Congress adopted the policy of dollar-for-dollar cooperation with the States and local governmental agencies in water-resources investigations of the U.S. Geological Survey. In 1937 a program of ground-water investigations was started in cooperation with the Oklahoma Geological Survey, and in 1949 this program was expanded to include cooperation with the Oklahoma Planning and Resources Board. In 1957 the State Legislature created the Oklahoma Water Resources Board as the principal State water agency and it became the principal local cooperator. The Ground Water Branch of the U.S. Geological Survey collects, analyzes, and evaluates basic information on ground-water resources and prepares interpretive reports based on those data. Cooperative ground-water work was first concentrated in the Panhandle counties. During World War II most work was related to problems of water supply for defense requirements. Since 1945 detailed investigations of ground-water availability have been made in 11 areas, chiefly in the western and central parts of the State. In addition, water levels in more than 300 wells are measured periodically, principally in the western half of the State. In Oklahoma current studies are directed toward determining the source, occurrence, and availability of ground water and toward estimating the quantity of water and rate of replenishment to specific areas and water-bearing formations. Ground water plays an important role in the economy of the State. It is

    Full Text Available The issue of whether to establish Specialist Chambers within the Kosovo justice system for alleged war crimes committed in Kosovo has been, arguably, one of the most heated debates not only from a political and social point of view, but also from a legal one. While the required amendments in the Constitution and several laws of Kosovo necessary to establish the Specialist Chambers in furtherance of the agreement dated 14 April 2014 between the Republic of Kosovo and the European Union on the Mission of the European Union Rule of Law Mission in Kosovo (“EULEX” will certainly create heated debates in the political level, one may argue that the legal issues that are expected to be encountered when the Specialist Chambers will be operational, may be even more pressing. This is in consideration of the peculiar nature of the Specialist Chambers, which are meant to have their basis within the laws of Kosovo, but at the same time, be independent from them and from control of Kosovo authorities. The purpose of this article is to delineate the possible legal issues that might confront the Specialist Chambers of Kosovo. Its main argument is that, while the Specialist Chambers seem to follow the experience of other hybrid internationalised courts, it still differs from them in some aspects. The challenges that the new Specialist Chambers may need to tackle deal with its jurisdiction and position within the Kosovo Judicial system, and its legitimacy and legal basis.

  18. Factors supporting good partnership working between generalist and specialist palliative care services: a systematic review.

    2012-05-01

    The care that most people receive at the end of their lives is provided not by specialist palliative care professionals but by generalists such as GPs, district nurses and others who have not undertaken specialist training in palliative care. A key focus of recent UK policy is improving partnership working across the spectrum of palliative care provision. However there is little evidence to suggest factors which support collaborative working between specialist and generalist palliative care providers. To explore factors that support partnership working between specialist and generalist palliative care providers. Systematic review. A systematic review of studies relating to partnership working between specialist and generalist palliative care providers was undertaken. Six electronic databases were searched for papers published up until January 2011. Of the 159 articles initially identified, 22 papers met the criteria for inclusion. Factors supporting good partnership working included: good communication between providers; clear definition of roles and responsibilities; opportunities for shared learning and education; appropriate and timely access to specialist palliative care services; and coordinated care. Multiple examples exist of good partnership working between specialist and generalist providers; however, there is little consistency regarding how models of collaborative working are developed, and which models are most effective. Little is known about the direct impact of collaborative working on patient outcomes. Further research is required to gain the direct perspectives of health professionals and patients regarding collaborative working in palliative care, and to develop appropriate and cost-effective models for partnership working.

    Delayed access to specialist care for emergency patients is associated with increased risk of morbidity and mortality, and increased patient anxiety. (1) To provide timelier access to inpatient and urgent outpatient specialist care for emergency patients. (2) To influence multiple stakeholders to modify their traditional practices and sustain changes. National University Hospital of Singapore, an academic medical centre with 997 beds in Singapore and over 34 sub-specialties. A set of six interventions was implemented to meet three goals: (1) provide timely access to urgent outpatient specialist care requested by the emergency department ED; (2) increase early inpatient discharges (in order to better match timing of emergency admissions); and (3) provide earlier defined care by inpatient specialists at the ED. An eight-step organisational change management plan was implemented to ensure all specialties complied with the changes. The goals were achieved. (1) Specialist outpatient appointments given within the timeframe requested by the ED doctor increased from 51.7% to 80.8%. (2) Early discharges increased from 11.9% to 26.6% and were sustained at 27.2%. (3) 84% of eligible patients received earlier defined specialist care at the ED. The change management achieved excellent clinician compliance rates ranging from 84% to 100%. However the median wait for admission remained unchanged. The interventions reduced the time for ED patients to access specialist outpatient and inpatient care. The systematic organisational change management approach resulted in sustained compliance.

    2006-10-01

    Full Text Available Abstract Background Although medical specialists traditionally hold negative views towards working part-time, the practice of medicine has evolved. Given the trend towards more part-time work and that there is no evidence that it compromises the quality of care, attitudes towards part-time work may have changed as well in recent years. The aim of this paper was to examine the possible changes in attitudes towards part-time work among specialists in internal medicine between 1996 and 2004. Moreover, we wanted to determine whether these attitudes were associated with individual characteristics (age, gender, investments in work and whether attitudes of specialists within a partnership showed more resemblance than specialists' attitudes from different partnerships. Methods Two samples were used in this study: data of a survey conducted in 1996 and in 2004. After selecting internal medicine specialists working in general hospitals in The Netherlands, the sample consisted of 219 specialists in 1996 and 363 specialists in 2004. They were sent a questionnaire, including topics on the attitudes towards part-time work. Results Internal medicine specialists' attitudes towards working part-time became slightly more positive between 1996 and 2004. Full-time working specialists in 2004 still expressed concerns regarding the investments of part-timers in overhead tasks, the flexibility of task division, efficiency, communication and continuity of care. In 1996 gender was the only predictor of the attitude, in 2004 being a full- or a part-timer, age and the time invested in work were associated with this attitude. Furthermore, specialists' attitudes were not found to cluster much within partnerships. Conclusion In spite of the increasing number of specialists working or preferring to work part-time, part-time practice among internal medicine specialists seems not to be fully accepted. The results indicate that the attitudes are no longer gender based, but are

    Rajka Bračun Sova

    2015-12-01

    Full Text Available Since Bourdieu, it has been argued that art appreciation requires “knowledge”. The focus of this qualitative study was to examine art appreciation as a learned competence by exploring two different groups of museum visitors: art specialists and art non-specialists. The research was conducted at Moderna galerija in Ljubljana. Twenty-three adults were recruited and accompanied during their visit to the museum. Participants were requested to “think out loud”, which meant to talk about what they saw, thought, and felt about the artworks. There was a short interview conducted with each participant before entering the museum to gain insight into their art-related and museum-visiting experience. The analysis of the data revealed that some processes of art appreciation were similar within the two groups. Both art specialists and art non-specialists interact with museum objects physically and intellectually; they see contents and formal qualities as a whole; they respond emotionally to artworks; appreciation includes their personal experience; they search museum interpretation/information for their understanding. Some noticeable differences were found. Art specialists respond to artworks with more understanding and are willing to put more effort into art appreciation, whereas art non-specialists respond with less understanding and put less effort into art appreciation. This paper focuses on the differences between the two groups; reflective and spontaneous appreciation of art, objective and subjective appreciation of art and the effort put into art appreciation. The paper ends with a discussion of the implications of the study for the teaching of art and museum education.

  9. Specialist geriatric services: A necessity within the radiotherapy workforce

    2016-06-01

    Full Text Available A large proportion of cancer patients receiving outpatient chemotherapy and radiotherapy services are more than 70 years old. For this subgroup of patients, a general clinical evaluation may not be sufficient to determine an individual’s treatment strategy as there are other non-stand¬ard medical issues that concern the elderlies such as polypharmacy, the need for extra social care, and accessibility to information[1]. In addition, these patients also have increased risks of reduced mobility, as well as emotional and financial difficulties.Therefore, it is necessary to incorporate geriatric as-sessment (GA into routine medical practice in order to improve individualized care[2,3]. Geriatric assessment is a comprehensive process that evaluates a senior patient’s medical, emotional, social and functional capacity[4]. In the current issue of AMOR, Louise Hogan and Anita O’Donovan from Trinity College Dublin evaluated the experience of elderly patients who used radiotherapy services in Ireland[5]. This was conducted through a number of questions directed at a focus group of elderly cancer patients, assessing different spheres of social dif-ficulties associated with undergoing radiotherapy in this age group.They found that it is important to focus on providing essential information to patients in a calm setting at an appropriate time. They also recommended establishing proper support groups for elderly patients receiving radiotherapy, as well as encouraging one-to-one discus-sions between patients and members of the healthcare team regarding possible side effects of treatment.In conclusion, it is evident that specialist geriatric services within radiotherapy departments are a necessity, given the large number of elderly patients receiving radi-otherapy and the specificity of their medical and social needs. It is also believed that a treatment strategy based on a personalized GA for elderly patients will improve the overall treatment efficacy

    2017-06-01

    Full Text Available One of the things that drew me to grounded theory from the beginning was Glaser and Strauss’ assertion in The Discovery of Grounded Theory that it was useful as a “theoretical foothold” for practical applications (p. 268. From this, when I was a Ph.D student studying under Glaser and Strauss in the early 1970s, I devised a GT based approach to action I later came to call “grounded action.” In this short paper I’ll present a very brief sketch of an anger management program I developed in 1992, using grounded action. I began my research by attending a two-day anger management training workshop designed for training professionals in the most commonly used anger management model. Like other intervention programs I had seen, this model took a psychologizing and pathologizing approach to the issue. Following this, I sat through the full course of an anger management program that used this model, observing the reactions of the participants and the approach of the facilitator. Following each session I conducted open-ended interviews with most of the participants, either individually or in groups of two or three. I had also done previous research in counseling and social work contexts that turned out to be very relevant to an anger management program design.

Through simulation by HFSS software, in case of 10 dBW radiation power, the phased-array antenna’s EIRP can be larger than 15 dBW in any azimuth of 360o with the large scanning angle of ±80o. Meanwhile, the simulated axial ratio of normal direction is flat in the working band and lower than 0.5 dB. The antenna was assembled and measured. Results show that EIRP is larger than 15 dBW in all the scanning range. Meanwhile, the measured axial ratio of normal direction is flat and lower than 1 dB in the working band. All the measured data matches well with the simulation.

    A prototype space-based cloud radar has been developed and was installed on an airplane to observe a precipitation system over Tianjin,China in July 2010.Ground-based S-band and Ka-band radars were used to examine the observational capability of the prototype. A cross-comparison algorithm between different wavelengths,spatial resolutions and platform radars is presented.The reflectivity biases,correlation coefficients and standard deviations between the radars are analyzed.The equivalent reflectivity bias between the S- and Ka-band radars were simulated with a given raindrop size distribution.The results indicated that reflectivity bias between the S- and Ka-band radars due to scattering properties was less than 5 dB,and for weak precipitation the bias was negligible. The prototype space-based cloud radar was able to measure a reasonable vertical profile of reflectivity,but the reflectivity below an altitude of 1.5 km above ground level was obscured by ground clutter.The measured reflectivity by the prototype space-based cloud radar was approximately 10.9 dB stronger than that by the S-band Doppler radar (SA radar),and 13.7 dB stronger than that by the ground-based cloud radar.The reflectivity measured by the SA radar was 0.4 dB stronger than that by the ground-based cloud radar.This study could provide a method for the quantitative examination of the observation ability for space-based radars.

    This article describes a study that used a qualitative approach, purposive sampling and semi-structured telephone interviews conducted with specialist palliative care nurses from six rural community teams in England. The study investigated how services were organised and the issues of delivering specialist palliative nursing care in a rural area. Qualitative content analysis was used to analyse the data. The findings showed many similarities in that the majority of patients in rural areas were not accessing hospice services and there was a greater reliance on care at home. However, the challenges in delivering care ranged from managing patient expectations, geographical distance, lack of technology to support remote working and education for the specialist palliative care teams. The study makes specific recommendations for rural community specialist palliative care teams.

    Contracting in private sector is promoted in developing countries facing human resources shortages as a challenge to reduce maternal mortality. This study explored provision, practice, performance, barriers to execution and views about contracting in specialists for emergency obstetric care (EmOC) in rural India. Facility survey was conducted in all secondary and tertiary public health facilities (44) in three heterogeneous districts in Maharashtra state of India. Interviews (42) were conducted with programme managers and district and block level officials and with public and private EmOC specialists. Locations of private obstetricians in the study districts were identified and mapped. Two schemes, namely Janani Suraksha Yojana and Indian Public Health standards (IPHS) provided for contracting in EmOC specialists. The IPHS provision was chosen for use mainly due to greater sum for contracting in (US $ 30/service episode vs.300 US$/month). The positions of EmOC specialists were vacant in 83% of all facilities that hence had a potential for contracting in EmOC specialists. Private specialists were contracted in at 20% such facilities. The contracting in of specialists did not greatly increase EmOC service outputs at facilities, except in facilities with determined leadership. Contracting in specialists was useful for non emergency conditions, but not for obstetric emergencies. The contracts were more of a relational nature with poor monitoring structures. Inadequate infrastructure, longer distance to private specialists, insufficient financial provision for contracting in, and poor management capacities were barriers to effective implementation of contracting in. Dependency on the private sector was a concern among public partners while the private partners viewed contracting in as an opportunity to gain experience and credibility. Density and geographic distribution of private specialists are important influencing factors in determining feasibility and use of

  11. Part-time and full-time medical specialists, are there differences in allocation of time?

    Directory of Open Access Journals (Sweden)

    2006-03-01

    Full Text Available Abstract Background An increasing number of medical specialists prefer to work part-time. This development can be found worldwide. Problems to be faced in the realization of part-time work in medicine include the division of night and weekend shifts, as well as communication between physicians and continuity of care. People tend to think that physicians working part-time are less devoted to their work, implying that full-time physicians complete a greater number of tasks. The central question in this article is whether part-time medical specialists allocate their time differently to their tasks than full-time medical specialists. Methods A questionnaire was sent by mail to all internists (N = 817, surgeons (N = 693 and radiologists (N = 621 working in general hospitals in the Netherlands. Questions were asked about the actual situation, such as hours worked and night and weekend shifts. The response was 53% (n = 411 for internists, 52% (n = 359 for surgeons, and 36% (n = 213 for radiologists. Due to non-response on specific questions there were 367 internists, 316 surgeons, and 71 radiologists included in the analyses. Multilevel analyses were used to analyze the data. Results Part-time medical specialists do not spend proportionally more time on direct patient care. With respect to night and weekend shifts, part-time medical specialists account for proportionally more or an equal share of these shifts. The number of hours worked per FTE is higher for part-time than for full-time medical specialists, although this difference is only significant for surgeons. Conclusion In general, part-time medical specialists do their share of the job. However, we focussed on input only. Besides input, output like the numbers of services provided deserves attention as well. The trend in medicine towards more part-time work has an important consequence: more medical specialists are needed to get the work done. Therefore, a greater number of medical specialists

  16. Can plant resistance to specialist herbivores be explained by plant chemistry or resource use strategy?

    Science.gov (United States)

    Kirk, Heather; Vrieling, Klaas; Pelser, Pieter B; Schaffner, Urs

    2012-04-01

    At both a macro- and micro-evolutionary level, selection of and performance on host plants by specialist herbivores are thought to be governed partially by host plant chemistry. Thus far, there is little evidence to suggest that specialists can detect small structural differences in secondary metabolites of their hosts, or that such differences affect host choice or performance of specialists. We tested whether phytochemical differences between closely related plant species are correlated with specialist host choice. We conducted no-choice feeding trials using 17 plant species of three genera of tribe Senecioneae (Jacobaea, Packera, and Senecio; Asteraceae) and a more distantly related species (Cynoglossum officinale; Boraginaceae) containing pyrrolizidine alkaloids (PAs), and four PA-sequestering specialist herbivores of the genus Longitarsus (Chrysomelidae). We also assessed whether variation in feeding by specialist herbivores is attributable to different resource use strategies of the tested plant species. Plant resource use strategy was quantified by measuring leaf dry matter content, which is related to both plant nutritive value and to plant investment in quantitative defences. We found no evidence that intra-generic differences in PA profiles affect feeding by specialist herbivores. Instead, our results indicate that decisions to begin feeding are related to plant resource use strategy, while decisions to continue feeding are not based on any plant characteristics measured in this study. These findings imply that PA composition does not significantly affect host choice by these specialist herbivores. Leaf dry matter content is somewhat phylogenetically conserved, indicating that plants may have difficulty altering resource use strategy in response to selection pressure by herbivores and other environmental factors on an evolutionary time scale.

  2. Infrasonic induced ground motions

    Science.gov (United States)

    Lin, Ting-Li

    On January 28, 2004, the CERI seismic network recorded seismic signals generated by an unknown source. Our conclusion is that the acoustic waves were initiated by an explosive source near the ground surface. The meteorological temperature and effective sound speed profiles suggested existence of an efficient near-surface waveguide that allowed the acoustic disturbance to propagate to large distances. An explosion occurring in an area of forest and farms would have limited the number of eyewitnesses. Resolution of the source might be possible by experiment or by detailed analysis of the ground motion data. A seismo-acoustic array was built to investigate thunder-induced ground motions. Two thunder events with similar N-wave waveforms but different horizontal slownesses are chosen to evaluate the credibility of using thunder as a seismic source. These impulsive acoustic waves excited P and S reverberations in the near surface that depend on both the incident wave horizontal slowness and the velocity structure in the upper 30 meters. Nineteen thunder events were chosen to further investigate the seismo-acoustic coupling. The consistent incident slowness differences between acoustic pressure and ground motions suggest that ground reverberations were first initiated somewhat away from the array. Acoustic and seismic signals were used to generate the time-domain transfer function through the deconvolution technique. Possible non-linear interaction for acoustic propagation into the soil at the surface was observed. The reverse radial initial motions suggest a low Poisson's ratio for the near-surface layer. The acoustic-to-seismic transfer functions show a consistent reverberation series of the Rayleigh wave type, which has a systematic dispersion relation to incident slownesses inferred from the seismic ground velocity. Air-coupled Rayleigh wave dispersion was used to quantitatively constrain the near-surface site structure with constraints afforded by near-surface body

    Full Text Available Higher utilization of complementary and alternative medicine (CAM is commonly explained by dissatisfaction or disappointment with conventional medical treatment. To explore, at two points in time in Israel, the associations between six domains of satisfaction (attitude, length of visits, availability, information sharing, perceived quality of care and overall with conventional family physicians' and specialists' services and the likelihood of consulting CAM providers. This is a secondary analysis of interviews, which were conducted with 2000 persons in 1993 and 2500 persons in 2000, representing the Israeli Jewish urban population aged 45–75 in those years. Bivariate and multivariate analyses were used in the investigation. In 1993, users of CAM were less satisfied than non-users with both family physicians' and specialists' care. Lower satisfaction with the attitude of, the amount of information sharing by and in general with family physicians, and with the length of visits and perceived quality of care of specialists were significantly associated with CAM use. In 2000, lower satisfaction with specialists' attitude, length of visits, availability and in general was significantly related to the use of CAM. Lower satisfaction with family physicians and specialists is significantly associated with consulting CAM providers. However, with CAM becoming a mainstream medical care specialty in its own, lower satisfaction with conventional medicine specialists becomes the most important factor.

    Full Text Available Subject specialists are important assets in academic and research libraries. They possess not only the specialized knowledge of a particular subject field, but also the skills in library and information services. Looming shortage of qualified subject specialists resulting from the retirement of current professionals, most likely the baby-boomer generation, persuasively suggests that education and training are in urgent need of rethinking. This empirical study was conducted within the context of Library and Information Science education and academic librarianship in North America. Survey, content analysis, and focus group were employed as data collection methods. This study aims to analyze the status of LIS education for subject specialists, education needs and personal attributes of subject specialists, and the qualifications and responsibilities of becoming subject specialists. The goal of the study is to understand the knowledge, skills, and attitude of becoming subject specialists. Results of the study may provide insight into planning of formal curriculum and on-the-job training. [Article content in Chinese

    Full Text Available Germany is facing a shortage of young family doctors. In search of possible reasons the aim of this study was to explore the perception of specialists on family doctors. Within a qualitative study 16 medical specialists from different fields in hospital and outpatient care setting were interviewed. Interviews were analysed using qualitative content analysis according to Mayring. Most of the interviewed specialists have a positive view on family doctors although a certain depreciative assumption is resonated in a number of statements. According to the specialists, family doctors enjoy a high status in public, even if social processes of change may have a negative influence on their rather old-fashioned image. Specialists find that family medicine is underrepresented in university education suffering from an upgrading of specialized disciplines. Altogether the majority of the interviewed specialists certify family doctors in Germany a positive image. Lecturer in medical education and training should be aware of their key role in the career choices of young trainees and avoid degradation or upgrading of certain medical disciplines. Interlinked measures on different levels focusing on the improvement of working conditions and representation at the universities would be needed to regain attractiveness for the family doctor's profession as a career choice for young doctors.

    The Dutch postgraduate medical training has been revised to focus on seven competencies. The role as manager is one of these competencies. Recent studies show that this competency receives little attention during the residency training. In an earlier study, we discovered that residents perceived their competency as managers to be moderate. In this study, we investigated how medical specialists perceived the managerial competencies of medical residents and their need for management education. In September 2010, a 46-item questionnaire was designed which examined medical specialists' perceptions of the competency and needs of residents in the field of medical management. Two hundred ninety-eight specialists were invited via email to participate. Hundred twenty-nine specialists (43.3%) responded to our survey. They rated the residents' competencies in contract negotiating skills, knowledge of the healthcare system, and specialist department poorly. They felt that residents were competent in updating their medical knowledge. Ninety-four percent reported a need for training in management among residents. Preferred topics were time management and healthcare organization. The preferred training method was a workshop given during residency by an extramural expert. Dutch medical specialists perceive the management competencies of residents in some areas to be inadequate. They feel that training in medical management during residency is necessary.

    AN EMPIRICAL INVESTIGATION OF DIFFERENCES BETWEEN MATHEMATICS SPECIALISTS AND NON-SPECIALISTS AT THE HIGH-SCHOOL LEVEL in Cyprus - The data obtained from high-school seniors for the Third International Mathematics and Science Study (TIMSS) for the country of Cyprus appear to be contradictory. Although Cypriot students did not perform well in mathematics in elementary school, middle school, and in the non-advanced sectors of high school, students in advanced mathematics courses in high school managed to perform exceptionally well. In seeking to account for this apparent disparity, the present study examines the differences between mathematics specialists and non-specialists at the high-school level and discusses the implications that these have for teaching practice. It shows how students educated in an environment that might not be optimal for producing high-achieving students in mathematics and science in elementary and middle school (according to the TIMSS) might nonetheless manage to excel in these fields at the end of their schooling. In conclusion, the authors address the implications of their study for similar educational systems in other developing countries.

    2002-01-01

    Typically, ground staff scheduling is centrally planned for each terminal in an airport. The advantage of this is that the staff is efficiently utilized, but a disadvantage is that staff spends considerable time walking between stands. In this paper a decentralized approach for ground staff...... scheduling is investigated. The airport terminal is divided into zones, where each zone consists of a set of stands geographically next to each other. Staff is assigned to work in only one zone and the staff scheduling is planned decentralized for each zone. The advantage of this approach is that the staff...... work in a smaller area of the terminal and thus spends less time walking between stands. When planning decentralized the allocation of stands to flights influences the staff scheduling since the workload in a zone depends on which flights are allocated to stands in the zone. Hence solving the problem...

    We present an overview of results obtained from IBIS ground calibrations. The spectral and spatial characteristics of the detector planes and surrounding passive materials have been determined through a series of calibration campaigns. Measurements of pixel gain, energy resolution, detection uniformity, efficiency and imaging capability are presented. The key results obtained from the ground calibration have been: - optimization of the instrument tunable parameters, - determination of energy linearity for all detection modes, - determination of energy resolution as a function of energy through the range 20 keV - 3 MeV, - demonstration of imaging capability in each mode, - measurement of intrinsic detector non-uniformity and understanding of the effects of passive materials surrounding the detector plane, and - discovery (and closure) of various leakage paths through the passive shielding system.

    2011-05-01

    Many models for the acoustical properties of rigid-porous media require knowledge of parameter values that are not available for outdoor ground surfaces. The relationship used between tortuosity and porosity for stacked spheres results in five characteristic impedance models that require not more than two adjustable parameters. These models and hard-backed-layer versions are considered further through numerical fitting of 42 short range level difference spectra measured over various ground surfaces. For all but eight sites, slit-pore, phenomenological and variable porosity models yield lower fitting errors than those given by the widely used one-parameter semi-empirical model. Data for 12 of 26 grassland sites and for three beech wood sites are fitted better by hard-backed-layer models. Parameter values obtained by fitting slit-pore and phenomenological models to data for relatively low flow resistivity grounds, such as forest floors, porous asphalt, and gravel, are consistent with values that have been obtained non-acoustically. Three impedance models yield reasonable fits to a narrow band excess attenuation spectrum measured at short range over railway ballast but, if extended reaction is taken into account, the hard-backed-layer version of the slit-pore model gives the most reasonable parameter values.

    Advances in mobile technology mean vets are now commonly presented with videos of paroxysmal events by clients, but the consistency of the interpretation of these videos has not been investigated. The objective of this study was to investigate the level of agreement between vets (both neurology specialists and non-specialists) on the description and classification of videos depicting paroxysmal events, without knowing any results of diagnostic workup. An online questionnaire study was conducted, where participants watched 100 videos of dogs and cats exhibiting paroxysmal events and answered questions regarding: epileptic seizure presence (yes/no), seizure type, consciousness status, and the presence of motor, autonomic and neurobehavioural signs. Agreement statistics (percentage agreement and kappa) calculated for each variable, with prevalence indices calculated to aid their interpretation. Only a fair level of agreement (κ = 0.40) was found for epileptic seizure presence. Overall agreement of seizure type was moderate (κ = 0.44), with primary generalised seizures showing the highest level of agreement (κ = 0.60), and focal the lowest (κ =0.31). Fair agreement was found for consciousness status and the presence of autonomic signs (κ = 0.21-0.40), but poor agreement for neurobehavioral signs (κ = 0.16). Agreement for motor signs ranged from poor (κ = ≤ 0.20) to moderate (κ = 0.41-0.60). Differences between specialists and non-specialists were identified. The relatively low levels of agreement described here highlight the need for further discussions between neurology experts regarding classifying and describing epileptic seizures, and additional training of non-specialists to facilitate accurate diagnosis. There is a need for diagnostic tools (e.g. electroencephalogram) able to differentiate between epileptic and non-epileptic paroxysms.

    BACKGROUND Hypertension is common in patients with atrial fibrillation (AF) and is an important cause of stroke. OBJECTIVES To determine how effectively hypertension is managed among specialist-treated outpatients with AF. METHODS Investigators reviewed the charts of patients with a diagnosis of AF cared for by medical specialists to determine the change in blood pressure, patterns of antihypertensive drug use and the role of the specialist in the management of hypertension. RESULTS Of 209 patients with AF, 118 had a history of hypertension or an office blood pressure greater than 140/90 mmHg. Blood pressure was measured at 73% of all visits. Hypertension was identified as an important problem in 57% of patients and antihypertensive therapy was either initiated or suggested in 77%. One year after the initial specialist visit, systolic blood pressure was significantly lower (140±20 mmHg at one year versus 148±23 mmHg initially; P=0.015); however, there was no change in diastolic blood pressure (80±12 mmHg at one year versus 81±16 mmHg initially; P=0.602) and only 50% of patients had a blood pressure less than 140/90 mmHg. In contrast, the percentage of patients receiving warfarin increased from 46% to 78% (P=0.0001). CONCLUSIONS In patients treated by specialists for AF, systolic blood pressure is significantly reduced during follow-up; however, 50% of patients continue to have suboptimal blood pressure control. In many patients, hypertension is not identified as an important comorbid illness and antihypertensive therapy is neither recommended nor initiated by the specialist. Greater specialist involvement in the identification and treatment of hypertension in patients with AF could lead to an important, additional reduction in stroke. PMID:16685312

    In Australia and New Zealand, a critical mass of academic and clinical leadership in Adolescent Medicine has helped advance models of clinical services, drive investments in teaching and training, and strengthen research capacity over the past 30 years. There is growing recognition of the importance of influencing the training of adult physicians as well as paediatricians. The Royal Australasian College of Physicians (RACP) is responsible for overseeing all aspects of specialist physician training across the two countries. Following advocacy from adolescent physicians, the RACP is advancing a three-tier strategy to build greater specialist capacity and sustain leadership in adolescent and young adult medicine (AYAM). The first tier of the strategy supports universal training in adolescent and young adult health and medicine for all basic trainees in paediatric and adult medicine through an online training resource. The second and third tiers support advanced training in AYAM for specialist practice, based on an advanced training curriculum that has been approved by the RACP. The second tier is dual training; advanced trainees can undertake 2 years training in AYAM and 2 years training in another area of specialist practice. The third tier consists of 3 years of advanced training in AYAM. The RACP is currently seeking formal recognition from the Australian Government to have AYAM accredited, a process that will be subsequently undertaken in New Zealand. The RACP is expectant that the accreditation of specialist AYAM physicians will promote sustained academic and clinical leadership in AYAM to the benefit of future generations of young Australasians.

    Plants use a diverse mix of defenses against herbivores, including multiple secondary metabolites, which often affect herbivores synergistically. Chemical defenses also can affect natural enemies of herbivores via limiting herbivore populations or by affecting herbivore resistance to parasitoids. In this study, we performed feeding experiments to examine the synergistic effects of imides and amides (hereafter "amides") from Piper cenocladum and P. imperiale on specialist (Eois nympha, Geometridae) and generalist (Spodoptera frugiperda, Noctuidae) lepidopteran larvae. Each Piper species has three unique amides, and in each experiment, larvae were fed diets containing different concentrations of single amides or combinations of the three. The amides from P. imperiale had negative synergistic effects on generalist survival and specialist pupal mass, but had no effect on specialist survival. Piper cenocladum amides also acted synergistically to increase mortality caused by parasitoids, and the direct negative effects of mixtures on parasitoid resistance and pupal mass were stronger than indirect effects via changes in growth rate and approximate digestibility. Our results are consistent with plant defense theory that predicts different effects of plant chemistry on generalist versus adapted specialist herbivores. The toxicity of Piper amide mixtures to generalist herbivores are standard bottom-up effects, while specialists experienced the top-down mediated effect of mixtures causing reduced parasitoid resistance and associated decreases in pupal mass.

    Attitudes of teaching medical specialists are important in shaping medical students' attitudes toward psychiatry. Data on attitudes of teaching medical specialists of India toward psychiatry are limited. The aim was to study the attitude of teaching medical specialists of an academic medical center in East India toward psychiatry. This was a cross-sectional descriptive study. We administered attitude toward psychiatry-30 (ATP 30) scale to teaching medical specialists of the All India Institute of Medical Sciences, Bhubaneswar, based on convenience sampling. Of 104 specialists contacted, 88 returned the completed questionnaire. We carried out descriptive statistical analysis and expressed results in mean and standard deviation. We analyzed the association of demographic characteristics, specialization, and duration of professional experience with total ATP scores using Chi-square test. We used subgroup analysis to compare mean ATP scores in different demographic and professional groups. We used independent t-test and ANOVA for between group comparisons. The response rate was 84.62% with a mean ATP score of 88.60. Female gender and having a family member with mental illness was significantly associated with favorable ATP. Notable findings were that 97% of participants were favorable toward patients with psychiatric illness, 90% felt psychiatric interventions as effective whereas 87% found psychiatry unappealing and 52% said that they would not have liked to be a psychiatrist. While favorable attitudes toward patients with psychiatric illness and psychiatric interventions may mean better patient care; unfavorable attitudes toward psychiatry as a career choice may adversely affect postgraduate recruitment rates.

  3. Host plant invests in growth rather than chemical defense when attacked by a specialist herbivore.

    Plant defensive compounds may be a cost rather than a benefit when plants are attacked by specialist insects that may overcome chemical barriers by strategies such as sequestering plant compounds. Plants may respond to specialist herbivores by compensatory growth rather than chemical defense. To explore the use of defensive chemistry vs. compensatory growth we studied Brugmansia suaveolens (Solanaceae) and the specialist larvae of the ithomiine butterfly Placidina euryanassa, which sequester defensive tropane alkaloids (TAs) from this host plant. We investigated whether the concentration of TAs in B. suaveolens was changed by P. euryanassa damage, and whether plants invest in growth, when damaged by the specialist. Larvae feeding during 24 hr significantly decreased TAs in damaged plants, but they returned to control levels after 15 days without damage. Damaged and undamaged plants did not differ significantly in leaf area after 15 days, indicating compensatory growth. Our results suggest that B. suaveolens responds to herbivory by the specialist P. euryanassa by investing in growth rather than chemical defense.

    This study shows that, in an unregulated fee-setting environment, specialist physicians practise price discrimination on the basis of their patients' income status. Our results are consistent with profit maximisation behaviour by specialists. These findings are based on a large population survey that is linked to administrative medical claims records. We find that, for an initial consultation, specialist physicians charge their high-income patients AU$26 more than their low-income patients. While this gap equates to a 19% lower fees for the poorest patients (bottom 25% of the household income distribution), it is unlikely to remove the substantial financial barriers they face in accessing specialist care. There are large variations across specialties, with neurologists exhibiting the largest fee gap between the high-income and low-income patients. Several possible channels for deducing the patient's income are examined. We find that patient characteristics such as age, health concession card status and private health insurance status are all used by specialists as proxies for income status. These characteristics are particularly important to further practise price discrimination among the low-income patients but are less relevant for the high-income patients.

    2014-06-01

    Reflective practice was used as a process of self-inquiry and transformation in a PhD study of my specialist role in single and family homelessness. New to homelessness when I embarked on the study, there was little to guide my nursing practice and, notably, there was insufficient research evidence to demonstrate the effectiveness of specialist practice with homeless people. Through my reflexive narrative study, that research gap was addressed. The aim of the narrative was to inform the reader of the reflexive journey and my transformation as a specialist practitioner in homeless health care, and to invite readers to reflect on their own perceptions of homelessness along with the health needs of homeless people. Study findings illuminated the key ethical role that mainstream health professionals, including specialist community public health nurses (SCPHNs), have towards effective engagement to reduce suffering and prevent homeless people and families falling through the net of care. As my research progressed I metaphorically understood the specialist practitioner role as a clinical and strategic 'net-weaver' in a net of care between homeless people, multi-agency partnerships, community and acute health services, and in education.

    This paper describes the goals of the American Society of Health-System Pharmacists' Pharmacy Practice Model Initiative (PPMI) and its recommendations for health-system pharmacy practice transformation to meet future patient care needs and elevate the role of pharmacists as patient care providers. PPMI envisions a future in which pharmacists have greater responsibility for medication-related outcomes and technicians assume greater responsibility for product-related activities. Although the PPMI recommendations have elevated the level of practice in many settings, they also potentially affect existing clinical pharmacists, in general, and clinical pharmacy specialists, in particular. Moreover, although more consistent patient care can be achieved with an expanded team of pharmacist providers, the role of clinical pharmacy specialists must not be diminished, especially in the care of complex patients and populations. Specialist practitioners with advanced training and credentials must be available to model and train pharmacists in generalist positions, residents, and students. Indeed, specialist practitioners are often the innovators and practice leaders. Negotiation between hospitals and pharmacy schools is needed to ensure a continuing role for academic clinical pharmacists and their contributions as educators and researchers. Lessons can be applied from disciplines such as nursing and medicine, which have developed new models of care involving effective collaboration between generalists and specialists. Several different pharmacy practice models have been described to meet the PPMI goals, based on available personnel and local goals. Studies measuring the impact of these new practice models are needed.

  7. Educational clinical supervision: meeting the needs of specialist community practitioner students and professional practice.

    In light of the possible demise of the community practice teacher, this paper proposes that a specific system of educationally led clinical supervision would benefit learning, teaching and assessing in the practice elements of specialist community practitioner education. Such a system would be additional to models of clinical supervision currently utilized in practice. An educative supervisory relationship would foster those skills and attributes essential for specialist community practice, enabling students to move toward mature responsible practice. It would provide experience of supportive frameworks that could be later utilized in professional practice. Clinical supervision specifically tailored for specialist community practitioner education would enable equity across branches and could be delivered in a variety of settings without a supervisor having to be 'on-site', thus benefiting comparatively isolated students in practice nursing and occupational health. To work successfully, educationally led clinical supervision necessitates a joint response by educational institutions and those practices where specialist community students undertake assessed placements. Without such a system in place to support specialist community practitioner courses, the standard of education and future practice cannot be assured.

  8. Mistletoe specialist frugivores: latterday "Johnny Appleseeds" or self‑serving market gardeners?

    Many plants use birds to disperse their propagules, but mistletoes are especially reliant on their services. As aerial parasites, mistletoe seeds need to be deposited upon branches of suitable hosts, and mistletoe specialist frugivores (from eight different avian families) have long been regarded as their coevolved dispersers. Like the pioneer Johnny 'Appleseed' Chapman who established nurseries that helped open up land for settlement, these birds are considered benevolent dispersers of this keystone resource and often invoked as illustrative examples of mutualistic interactions. We have compared recent research on these specialists with studies of other birds with broader diets (generalists) which also disperse mistletoe seed. Rather than mutualists, we suggest that mistletoe specialist frugivores are better considered exploitative, with multiple lineages evolving independently to capitalize on this reliable, nutritious resource. Although mistletoe specialist frugivores are quantitatively important seed dispersers in some regions, their specialized diet restricts them to areas with high mistletoe densities, resulting in contagious dispersal patterns. By intensifying existing infections, mistletoe specialist frugivores increase their own medium-term food security-akin to market gardeners profiting from intensive cultivation. Exploring the ecological and evolutionary implications of this proposition, we evaluate the consequences of different dispersal patterns on mistletoe fitness and highlight the neglected role of dietary generalists in the stabilization of plant-animal interactions.

    2016-02-01

    There is little in the literature describing hospital specialist palliative care units (PCUs) within the NHS. This paper describes how specialist PCUs can be set up within and be entirely funded by the NHS, and outlines some of the challenges and successes of the units. Having PCUs within hospitals has offered patients increased choice over their place of care and death; perhaps not surprisingly leading to a reduced death rate in the acute hospital. However, since the opening of the PCUs there has also been an increased home death rate. The PCUs are well received by patients, families and other staff within the hospital. We believe they offer a model for excellence in cost-effective inpatient specialist palliative care within the NHS.

    The current global nursing shortage challenges the provision of a well qualified and sustainable health workforce to meet future population health needs. An identified area of concern for New Zealand reaching health policy targets in chronic conditions management and primary health care is an adequate specialist nurse workforce supply. This article explores the New Zealand context underpinning this concern and contends that effective workforce planning would be supported by the development of a single unified framework for specialist nursing practice in New Zealand. A consistent national framework has the potential to support accurate data collection and enable service providers to identify and plan transparent and transferable pathways for specialist nursing service provision and development. Advanced practice nursing frameworks assist in increasing productivity through building an evidence base about advanced practice, enhancing consistency and equity of expertise; supporting a reduction in role duplication; and enabling succession planning and sustainability.

    Anderson, Katharine A

    2011-01-01

    Many organizations rely on the skills of innovative individuals to create value, including academic and government institutions, think tanks, and knowledge-based firms. Roughly speaking, workers in these fields can be divided into two categories: specialists, who have a deep knowledge of a single area, and generalists, who have knowledge in a wide variety of areas. In this paper, I examine an individual's choice to be a specialist or generalist. My model addresses two questions: first, under what conditions does it make sense for an individual to acquire skills in multiple areas, and second, are the decisions made by individuals optimal from an organizational perspective? I find that when problems are single-dimensional, and disciplinary boundaries are open, all workers will specialize. However, when there are barriers to working on problems in other fields, then there is a tradeoff between the depth of the specialist and the wider scope of problems the generalist has available. When problems are simple, havi...

    The purpose of this study was to explore the perceptions and experiences of health care clinicians working in multidisciplinary teams that include specialist heart failure nurses when caring for the management of heart failure patients. We used a qualitative in-depth interview study nested in a broader ethnographic study of unplanned admissions in heart failure patients (HoldFAST). We interviewed 24 clinicians across primary, secondary, and community care in 3 locations in the Midlands, South Central, and South West of England. Within a framework of the role and contribution of the heart failure specialist nurse, our study identified 2 thematic areas that the clinicians agreed still represent particular challenges when working with heart failure patients. The first was communication with patients, in particular explaining the diagnosis and helping patients to understand the condition. The participants recognized that such communication was most effective when they had a long-term relationship with patients and families and that the specialist nurse played an important part in achieving this relationship. The second was communication within the team. Multidisciplinary input was especially needed because of the complexity of many patients and issues around medications, and the participants believed the specialist nurse may facilitate team communication. The study highlights the role of specialist heart failure nurses in delivering education tailored to patients and facilitating better liaison among all clinicians, particularly when dealing with the management of comorbidities and drug regimens. The way in which specialist nurses were able to be caseworkers for their patients was perceived as a method of ensuring coordination and continuity of care. © 2015 Annals of Family Medicine, Inc.

    The theoretical background in this chapter is science and technology studies and actor network theory, enabling investigation of heterogeneity, agency and perfor-mative effects through ‘symmetric’ analysis. The concept of design is defined as being imaginative and mindful to a number of actors...... in a network of humans and non-humans, highlighting that design objects and the designer as an authority are constructed throughout this endeavour. The illustrative case example is drawn from product development in a rubber valve factory in Jutland in Denmark. The key contribution to a general core of design...... research is an articulation of design activity taking place as a middle ground and as an intermixture between a ‘scientific’ regime of knowledge transfer and a capital ‘D’ ‘Designerly’ regime of authoring....

    Wind noise is a problem in seismic surveys and can mask the seismic signals at low frequency. This research investigates ground motions caused by wind pressure and shear stress perturbations on the ground surface. A prediction of the ground displacement spectra using the measured ground properties and predicted pressure and shear stress at the ground surface is developed. Field measurements are conducted at a site having a flat terrain and low ambient seismic noise. Triaxial geophones are deployed at different depths to study the wind-induced ground vibrations as a function of depth and wind velocity. Comparison of the predicted to the measured wind-induced ground displacement spectra shows good agreement for the vertical component but significant underprediction for the horizontal components. To validate the theoretical model, a test experiment is designed to exert controlled normal pressure and shear stress on the ground using a vertical and a horizontal mass-spring apparatus. This experiment verifies the linear elastic rheology and the quasi-static displacements assumptions of the model. The results indicate that the existing surface shear stress models significantly underestimate the wind shear stress at the ground surface and the amplitude of the fluctuation shear stress must be of the same order of magnitude as the normal pressure. Measurement results show that mounting the geophones flush with the ground provides a significant reduction in wind noise on all three components of the geophone. Further reduction in wind noise with depth of burial is small for depths up to 40 cm.

    IMPACT OF DISABILITY: A survey of general practitioners, rheumatology specialists, and tourism specialists conducted by NEGMA-LERADS Laboratories demonstrated that subjects with osteoarthritis avoid vacation trips more readily than recreational activities. VACATION TRIPS ARE STILL POSSIBLE: Certain tourism organisms have nevertheless developed specialized services for disabled persons. Special emphasis is placed on adequate preparation before the vacation trip. PROBLEMS WITH WALKING: Many persons disabled by osteoarthritis do not require a wheel chair, yet have difficulty walking long distances. It is important to recognize the specific disabilities related to osteoarthritis and their effects on grip force and/or ambulation.

    The Field of Competence (FOC) of specialists in Physical and Rehabilitation Medicine (PRM) in Europe follows uniform basic principles described in the White Book of PRM in Europe. An agreed basis of the field of competence is the European Board curriculum for the PRM-specialist certification. However, due to national traditions, different health systems and other factors, PRM practice varies between regions and countries in Europe. Even within a country the professional practice of the individual doctor may vary because of the specific setting he or she is working in. For that reason this paper aims at a comprehensive description of the FOC in PRM. PRM specialists deal with/intervene in a wide range of diseases and functional deficits. Their interventions include, prevention of diseases and their complications, diagnosis of diseases, functional assessment, information and education of patients, families and professionals, treatments (physical modalities, drugs and other interventions). PRM interventions are often organized within PRM programmes of care. PRM interventions benefit from the involvement of PRM specialists in research. PRM specialists have knowledge of the rehabilitation process, team working, medical and physical treatments, rehabilitation technology, prevention and management of complications and methodology of research in the field. PRM specialists are involved in reducing functional consequences of many health conditions and manage functioning and disability in the respective patients. Diagnostic skills include all dimensions of body functions and structures, activities and participation issues relevant for the rehabilitation process. Additionally relevant contextual factors are assessed. PRM interventions range from medication, physical treatments, psychosocial interventions and rehabilitation technology. As PRM is based on the principles of evidence-based medicine PRM specialist are involved in research too. Quality management programs for PRM

    Demand for palliative care services in Canada will increase owing to an aging population and the evolving role of palliative care in non-malignant illness. Increasing healthcare demands continue to shape the clinical nurse specialist (CNS) role, especially in the area of palliative care. Clinical nurse specialists bring specialized knowledge, skills and leadership to the clinical setting to enhance patient and family care. This paper highlights the clinical leadership role of the CNS as triage leader for a hospital-based palliative care consulting team. Changes to the team's referral and triage processes are emphasized as key improvements to team efficiency and timely access to care for patients and families.

    2009-06-01

    Full Text Available Abstract Background The growing prevalence of diabetes and heightened awareness of the benefits of early and intensive disease management have increased service demands and expectations not only of primary care physicians but also of diabetes specialists. While research has addressed issues related to referral into specialist care, much less has been published about the transition from diabetes specialists back to primary care. Understanding the concerns of family physicians related to discharge of diabetes care from specialist centers can support the development of strategies that facilitate this transition and result in broader access to limited specialist services. This study was undertaken to explore primary care physician (PCP perspectives and concerns related to reassuming responsibility for diabetes care after referral to a specialized diabetes center. Methods Qualitative data were collected through three focus groups. Sessions were audio-taped and transcribed verbatim. Data were coded and sorted with themes identified using a constant comparison method. The study was undertaken through the regional academic referral center for adult diabetes care in Ottawa, Canada. Participants included 22 primary care physicians representing a variety of referral frequencies, practice types and settings. Results Participants described facilitators and barriers to successful transition of diabetes care at the provider, patient and systems level. Major facilitators included clear communication of a detailed, structured plan of care, ongoing access to specialist services for advice or re-referral, continuing education and mentoring for PCPs. Identified provider barriers were gaps in PCP knowledge and confidence related to diabetes treatment, excessive workload and competing time demands. Systems deterrents included reimbursement policies for health professionals and inadequate funding for diabetes medications and supplies. At the PCP-patient interface

    2010-06-01

    Grounded Theory Methodology (GTM) is a widely cited research approach based upon symbolic interaction with a focus on interaction, action and processes. Relatively recently, Discursive Psychology; a language-based interaction research approach also based on symbolic interaction, emerged. At present Discursive Psychology is principally cited in the social sciences literature. Given Discursive Psychology's symbolic interaction foundations, what relevance does this approach have for evolving GTM? A number of methodological challenges were posed by a study looking at humour in Clinical Nurse Specialist-patient interactions. This paper will use the phenomenon of spontaneous humour in healthcare interactions to illustrate the potential for a new form of GTM drawing on discursive approaches; Discursive GTM. First, the challenges presented by a study looking at spontaneous humour in Clinical Nurse Specialist-patient interactions are presented. Second, the research approach adopted to meet these challenges - Discursive GTM (DGTM) - is explicated and the results of the study are outlined. Third, the different GTM approaches and Discursive Psychology are compared and contrasted in relation to the DGTM approach adopted. Finally, the challenges and tensions of using DGTM as well as the opportunities afforded by the use of naturally occurring data are reviewed. The authors contend that a DGTM approach may be appropriate in analyzing certain phenomena. In particular, we highlight the potential contribution of naturally occurring data as an adjunct to researcher-elicited data. Thus, when exploring particular phenomena, a DGTM approach may address the potentially under-developed symbolic interaction tenet of language.

    Although they are critical to models of coordinated care, the relationship and communication between primary care providers (PCPs) and cancer specialists throughout the cancer continuum are poorly understood. By using predefined search terms, the authors conducted a systematic review of the literature in 3 databases to examine the relationship and communication between PCPs and cancer specialists. Among 301 articles identified, 35 met all inclusion criteria and were reviewed in-depth. Findings from qualitative, quantitative, and disaggregated mixed-methods studies were integrated using meta-synthesis. Six themes were identified and incorporated into a preliminary conceptual model of the PCP-cancer specialist relationship: 1) poor and delayed communication between PCPs and cancer specialists, 2) cancer specialists' endorsement of a specialist-based model of care, 3) PCPs' belief that they play an important role in the cancer continuum, 4) PCPs' willingness to participate in the cancer continuum, 5) cancer specialists' and PCPs' uncertainty regarding the PCP's oncology knowledge/experience, and 6) discrepancies between PCPs and cancer specialists regarding roles. These data indicate a pervasive need for improved communication, delineation, and coordination of responsibilities between PCPs and cancer specialists. Future interventions aimed at these deficiencies may improve patient and physician satisfaction and cancer care coordination. CA Cancer J Clin 2017;67:156-169. © 2016 American Cancer Society.

  19. Integration of early specialist palliative care in cancer care and patient related outcomes: A critical review of evidence

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Conclusions: In adult oncology, there is evidence to suggest early specialist palliative care improves HRQOL, mood, treatment decision-making, health care utilization, advanced care planning, patient satisfaction, and end-of-life care. There is moderate evidence to support the role of early specialist palliative care intervention in improvement of symptoms, survival, and health-related communication. There is limited evidence at present to support role of early specialist palliative care interventions in pediatric and geriatric oncology. Qualitative studies on barriers and negative patient outcomes may provide useful insights toward restructuring early specialist palliative care interventions.

    The purpose was to describe the number, demographic characteristics, work patterns, exit rates, and work perceptions of nurses in Ontario, Canada, in 4 specialty classifications: advanced practice nurse (APN)-clinical nurse specialist (CNS), APN-other, primary healthcare nurse practitioner [RN(extended class [EC])], and registered nurse (RN) with specialty certification. The objectives were to (1) describe how many qualified nurses are available by specialty class; (2) create a demographic profile of specialist nurses; (3) determine the proportions of specialist and nonspecialist nurses who leave (a) direct patient care and (b) nursing practice annually; (4) determine whether specialist and nonspecialist nurses differ in their self-ratings of work environment, job satisfaction, and intention to remain in nursing. Employment patterns refer to nurses' employment status (eg, full-time, part-time, casual), work duration (ie, length of employment in nurses and in current role), and work transitions (ie, movement in and out of the nursing workforce, and movement out of current role). A longitudinal analysis of the Ontario nurses' registration database from 2005 to 2010 and a survey of specialist nurses in Canada was conducted. The setting was Canada. The database sample consisted of 3 specialist groups, consisting of RN(EC), CNS, and APN-other, as well as 1 nonspecialist RN staff nurse group. The survey sample involved 359 nurses who were classified into groups based on self-reported job title and RN specialty-certification status. Data sources included College of Nurses of Ontario registration database and survey data. The study measures were the Nursing Work Index, a 4-item measure of job satisfaction, and 1-item measure of intent to leave current job. Nurses registered with the College of Nurses of Ontario were tracked over the study period to identify changes in their employment status with comparisons made between nurses employed in specialist roles and those

    Full Text Available To meet a critical and growing need for emergency physicians and emergency medicine resources worldwide, physicians must be trained to deliver time-sensitive interventions and lifesaving emergency care. Currently, there is no globally recognized, standard curriculum that defines the basic minimum standards for specialist trainees in emergency medicine. To address this deficit, the International Federation for Emergency Medicine (IFEM convened a committee of international physicians, health professionals, and other experts in emergency medicine and international emergency medicine development to outline a curriculum for training of specialists in emergency medicine. This curriculum document represents the consensus of recommendations by this committee. The curriculum is designed to provide a framework for educational programs in emergency medicine. The focus is on the basic minimum emergency medicine educational content that any emergency medicine physician specialist should be prepared to deliver on completion of a training program. It is designed not to be prescriptive but to assist educators and emergency medicine leadership to advance physician education in basic emergency medicine no matter the training venue. The content of this curriculum is relevant not just for communities with mature emergency medicine systems but in particular for developing nations or for nations seeking to expand emergency medicine within the current educational structure. We anticipate that there will be wide variability in how this curriculum is implemented and taught. This variability will reflect the existing educational milieu, the resources available, and the goals of the institutions’ educational leadership with regard to the training of emergency medicine specialists.

    AIMS: To evaluate the impact of patient education by specialist nurses on patients' understanding of interventional procedures, their anxiety levels and satisfaction with the given information. MATERIALS AND METHODS: Sixty patients attending the radiology department for gastrointestinal interventional procedures were interviewed. Patients were assessed using a combination of categorical and visual analogue scales. Parameters were assessed on admission and after additional information had been given by specialist nurses. After the procedure patients were asked to rate the quality of information given and their overall satisfaction. RESULTS: Four of the 60 patients were excluded due to a Mini Mental Test score of <7. Only 35 (62.5%) claimed to have been given information by the referring consultant. Fifty-three patients received additional information before formally giving consent, 50 (96.2%) from the specialist nurses. Patient anxiety before and after information did not significantly change (p=0.52), but there was significant improvement in levels of satisfaction (p=0.001) and perceived understanding (p<0.001). Patients rated overall quality of information at an average of 9.2/10 and overall satisfaction was high (median=9.1/10). CONCLUSION: The use of specialist nurses to educate patients greatly increases patient understanding. The process of informed consent is improved and patient satisfaction is increased.

    2012-09-01

    There are many external influences in today's market force that impair the relationship between the pain medicine specialist and the patient, and ultimately prevent optimal quality of care. This article explores the ethical challenges facing the pain medicine specialist in today's increasingly "business" environment and will offer solutions for maintaining the professionalism of pain medicine. Four commonly encountered bioethical principles in the practice of pain medicine are reviewed: beneficence, nonmaleficence, justice, and autonomy. The following ethical challenges of the pain medicine specialist are reviewed: practicing outside ones specialty area, practice characteristics, the consultant role, the economic lure of aggressive intervention, not evaluating for and treating comorbid psychopathology, reimbursement pressures, workers' compensation, and use of unproven methods. Solutions offered include collegial associations, social responsibility, legislative initiatives, pain education, interdisciplinary evaluation and treatment, improved relationships with third-party payers, reduced racial disparities, and ethics education. Ethics is the "roadmap" that enables the pain medicine specialist to navigate the increasingly murky waters of practicing pain management today by maintaining the professionalism necessary to combat today's "business" pressures.

    2016-05-01

    Today's technology provides new ways of consulting between patients and medical specialists in health care, such as videoconferencing and web-messaging. In this systematic review we assessed the effects of e-consulting between medical specialists and patients. We searched MEDLINE, EMBASE, Psychlit and Cochrane Library for randomized clinical trials assessing the use of e-consulting methods (videoconferencing (VC) or web-messaging (WM)), as compared to conventional care (face-to-face (FF) or telephone consultations (TC)) in a medical specialist setting. We extracted patient-related, physician-related, cost, time and follow-up outcomes. We included 21 trials, of which 17 addressed VC compared to FF, two compared WM with FF, one VC with TC, and one WM with TC. Physicians appeared to prefer face-to-face consultations over videoconferencing. Patients appeared to be as satisfied with videoconferencing as with face-to-face contacts, but preferred videoconferencing and web-messaging over telephone consultations. Videoconferencing was more expensive regarding equipment, but saved patient-related costs in terms of time, transportation, and missed work. Variable results were found for consult time and follow-up visits. We cautiously conclude that e-consulting seems a feasible alternative to medical specialists' face-to-face follow-up or telephone appointments, but may be less suitable for initial consultations requiring physical examination.

    Competition for resources is thought to play a critical role in both the origins and maintenance of biodiversity. Although numerous laboratory evolution experiments have confirmed that competition can be a key driver of adaptive diversification, few have demonstrated its role in the maintenance of the resulting diversity. We investigate the conditions that favour the origin and maintenance of alternative generalist and specialist resource-use phenotypes within the same population. Previously, we confirmed that competition for hosts among φ6 bacteriophage in a mixed novel (non-permissive) and ancestral (permissive) host microcosm triggered the evolution of a generalist phenotype capable of infecting both hosts. However, because the newly evolved generalists tended to competitively exclude the ancestral specialists, coexistence between the two phenotypes was rare. Here, we show that reducing the relative abundance of the novel host slowed the increase in frequency of the generalist phenotype, allowing sufficient time for the specialist to further adapt to the ancestral host. This adaptation resulted in 'evolutionary rescue' of the specialists, preventing their competitive exclusion by the generalists. Thus, our results suggest that competition promotes both the origin and maintenance of biodiversity when it is strong enough to favour a novel resource-use phenotype, but weak enough to allow adaptation of both the novel and ancestral phenotypes to their respective niches.
