  12. Neural Network Based Retrieval of Atmospheric Temperature Profile Using AMSU-A Observations

    2014-01-01

    Full Text Available The present study describes artificial neural network (ANN based approach for the retrieval of atmospheric temperature profiles from AMSU-A microwave temperature sounder. The nonlinear relationship between the temperature profiles and satellite brightness temperatures dictates the use of ANN, which is inherently nonlinear in nature. Since latitudinal variation of temperature is dominant one in the Earth’s atmosphere, separate network configurations have been established for different latitudinal belts, namely, tropics, mid-latitudes, and polar regions. Moreover, as surface emissivity in the microwave region of electromagnetic spectrum significantly influences the radiance (or equivalently the brightness temperature at the satellite altitude, separate algorithms have been developed for land and ocean for training the networks. Temperature profiles from National Center for Environmental Prediction (NCEP analysis and brightness temperature observations of AMSU-A onboard NOAA-19 for the year 2010 have been used for training of the networks. Further, the algorithm has been tested on the independent dataset comprising several months of 2012 AMSU-A observations. Finally, an error analysis has been performed by comparing retrieved profiles with collocated temperature profiles from NCEP. Errors in the tropical region are found to be less than those in the mid-latitude and polar regions. Also, in each region the errors over ocean are less than the corresponding ones over land.

    Brightness temperature observations from Microwave Sounding Unit and Advanced Microwave Sounding Unit-A (AMSU-A) on board National Oceanic and Atmospheric Administration (NOAA) satellites have been widely utilized for estimating the global climate trend in the troposphere and stratosphere. A common approach for deriving the trend is linear regression, which implicitly assumes the trend being a straight line over the whole length of a time series and is often highly sensitive to the data record length. This study explores a new adaptive and temporally local data analysis method - Ensemble Empirical Mode Decomposition (EEMD) - for estimating the global trends. In EEMD, a non-stationary time series is decomposed adaptively and locally into a sequence of amplitude-frequency modulated oscillatory components and a time-varying trend. The AMSU-A data from the NOAA-15 satellite over the time period from October 26, 1998 to August 7, 2010 are employed for this study. Using data over Amazon rainforest areas, it is shown that channel 3 is least sensitive to the orbital drift among four AMSU-A surface sensitive channels. The decadal trends of AMSU-A channel 3 and other eight channels in the troposphere and stratosphere are deduced and compared using both methods. It is shown that the decadal climate trends of most AMSU-A channels are nonlinear except for channels 3-4 in Northern Hemisphere only and channels 12-13. Although the decadal trend variation of the global average brightness temperature is no more than 0.2 K, the regional decadal trend variation could be more (less) than 3 K (-3 K) in high latitudes and over high terrains.

    Back propagation neural networks are used to retrieve atmospheric temperature profiles from NOAA-16 Advanced Microwave Sounding Unit-A (AMSU-A) measurements over East Asia. The collocated radiosonde observation and AMSU-A data over land in 2002-2003 are used to train the network, and the data over land in 2004 are used to test the network. A comparison with the multi-linear regression method shows that the neural network retrieval method can significantly improve the results in all weather conditions.When an offset of 0.5 K or a noise level of +0.2 K is added to all channels simultaneously, the increase in the overall root mean square (RMS) error is less than 0.1 K. Furthermore, an experiment is conducted to investigate the effects of the window channels on the retrieval. The results indicate that the brightness temperatures of window channels can provide significantly useful information on the temperature retrieval near the surface. Additionally, the RMS errors of the profiles retrieved with the trained neural network are compared with the errors from the International Advanced TOVS (ATOVS) Processing Package (IAPP).It is shown that the network-based algorithm can provide much better results in the experiment region and comparable results in other regions. It is also noted that the network can yield remarkably better results than IAPP at the low levels and at about the 250-hPa level in summer skies over ocean. Finally,the network-based retrieval algorithm developed herein is applied in retrieving the temperature anomalies of Typhoon Rananim from AMSU-A data.

    Korea Institute of Atmospheric Prediction Systems (KIAPS) has successfully implemented Local Ensemble Transform Kalman Filter (LETKF; Hunt et al. 2007) data assimilation system to NCAR CAM-Spectral Element model. This model has the same grid structure on the cubed sphere as KIAPS-Global Model now developing without any singularity, and has a strong advantage on the flexibility and scalability in the future high performance computing environment. The KIAPS-LETKF system (Kang et al. 2013) has also adopted most advanced data assimilation techniques such as an adaptive multiplicative inflation (Miyoshi 2012), an estimation of ensemble forecast sensitivity to observations (EFSO; Kalnay et al. 2012) and proactive quality control (PQC; Ota et al. 2013). With those promising tools in the KIAPS-LETKF system, we plan to assimilate conventional data as well as various remote sensing data such as AMSU-A, IASI, GPS RO, which an observation preprocessing team at KIAPS has processed. In this study, we will present our assimilation strategy of AMSU-A radiance data from NOAA and MetOp satellites and show preliminary results at the conference. As an observation operator for satellite radiance data, the Radiative Transfer Model for the TIROS Operational Vertical Sounder (RTTOV) version 10.2 (Saunders et al. 2012) has been installed.

    Two sets of assimilation experiments on a landfalling typhoon--Typhoon Dan (1999) over the western North Pacific were designed to compare the performances of two kinds of variational data assimilation schemes that are the 3-Dimensional Variational data assimilation of Mapped observation (3DVM) and the 4-dimensional variational data assimilation (4DVar). Results show that: (1) both the 3DVM and 4DVar successfully improved the simulations of typhoon intensity and track incorporating the satellite AMSU-A retrieved temperature and wind data into the initial conditions, and the 3DVM more significantly due to the flow-dependent of background error covariance matrix and observation error covariance matrix like 3- dimensional variational data assimilation (3DVar) circle; (2) inclusions of extra model integration iterations at each observation time in the 3DVM make it more consistent with prediction model; (3) the 3DVM is much more time-saving due to the exclusion of the adjoint technique in it.

    2006-01-01

    Full Text Available Two-dimensional radiance maps from Channel 9 (~60–90 hPa of the Advanced Microwave Sounding Unit (AMSU-A, acquired over southern Scandinavia on 14 January 2003, show plane-wave-like oscillations with a wavelength λh of ~400–500 km and peak brightness temperature amplitudes of up to 0.9 K. The wave-like pattern is observed in AMSU-A radiances from 8 overpasses of this region by 4 different satellites, revealing a growth in the disturbance amplitude from 00:00 UTC to 12:00 UTC and a change in its horizontal structure between 12:00 UTC and 20:00 UTC. Forecast and hindcast runs for 14 January 2003 using high-resolution global and regional numerical weather prediction (NWP models generate a lower stratospheric mountain wave over southern Scandinavia with peak 90 hPa temperature amplitudes of ~5–7 K at 12:00 UTC and a similar horizontal wavelength, packet width, phase structure and time evolution to the disturbance observed in AMSU-A radiances. The wave's vertical wavelength is ~12 km. These NWP fields are validated against radiosonde wind and temperature profiles and airborne lidar profiles of temperature and aerosol backscatter ratios acquired from the NASA DC-8 during the second SAGE III Ozone Loss and Validation Experiment (SOLVE II. Both the amplitude and phase of the stratospheric mountain wave in the various NWP fields agree well with localized perturbation features in these suborbital measurements. In particular, we show that this wave formed the type II polar stratospheric clouds measured by the DC-8 lidar. To compare directly with the AMSU-A data, we convert these validated NWP temperature fields into swath-scanned brightness temperatures using three-dimensional Channel 9 weighting functions and the actual AMSU-A scan patterns from each of the 8 overpasses of this region. These NWP-based brightness temperatures contain two-dimensional oscillations due to this resolved stratospheric mountain wave that have an amplitude, wavelength

    Full Text Available Using a simplified model of in-orbit radiance acquisition by the Advanced Microwave Sounding Unit (AMSU-A, we derive three-dimensional temperature weighting functions for Channel 9 measurements (peaking at ~60–90 hPa at all 30 cross-track beam positions and use them to investigate the sensitivity of these radiances to gravity waves. The vertical widths of the weighting functions limit detection to waves with vertical wavelengths of ≳10 km, with slightly better vertical wavelength sensitivity at the outermost scan angles due to the limb effect. Fourier Transforms of two-dimensional cross-track weighting functions reveal optimal sensitivity to cross-track wavelengths at the near-nadir scan angles, where horizontal measurement footprints are smallest. This sensitivity is greater for the AMSU-A on the Aqua satellite than for the identical instruments on the NOAA meteorological satellites, due to a lower orbit altitude and thus smaller horizontal footprints from antenna spreading. Small cross-track asymmetries in the radiance response to gravity waves are found that peak at the mid-range scan angles, with more symmetric responses at near-nadir and far off-nadir scan angles. Three-dimensional simulations show gravity wave oscillations imaged in horizontal AMSU-A radiance maps swept out by the scan pattern and satellite motion. A distorting curvature is added to imaged wave phase lines due to vertical variations in weighting function peaks with cross-track scan angle. This wave distortion is analogous to the well-known "limb darkening" and "limb brightening" of microwave radiances acquired from purely vertical background temperature profiles by cross-track scanners. Waves propagating along track are more visible in these images at the outermost scan angles than those propagating cross track, due to oversampling and narrower widths of the horizontal measurement footprints in the along track direction. Based on nominal noise floors and representative

    Atmospheric temperature is one of the most important climate variables. This observational study presents detailed descriptions of the temperature variability imprinted in the 9-year brightness temperature data acquired by the Advanced Microwave Sounding Unit-Instrument A (AMSU-A) aboard Aqua since September 2002 over tropical oceans. A non-linear, adaptive method called the Ensemble Joint Multiple Extraction has been employed to extract the principal modes of variability in the AMSU-A/Aqua data. The semi-annual, annual, quasi-biennial oscillation (QBO) modes and QBO-annual beat in the troposphere and the stratosphere have been successfully recovered. The modulation by the El Niño/Southern oscillation (ENSO) in the troposphere was found and correlates well with the Multivariate ENSO Index. The long-term variations during 2002-2011 reveal a cooling trend (-0.5 K/decade at 10 hPa) in the tropical stratosphere; the trend below the tropical tropopause is not statistically significant due to the length of our data. A new tropospheric near-annual mode (period ~1.6 years) was also revealed in the troposphere, whose existence was confirmed using National Centers for Environmental Prediction Reanalysis air temperature data. The near-annual mode in the troposphere is found to prevail in the eastern Pacific region and is coherent with a near-annual mode in the observed sea surface temperature over the Warm Pool region that has previously been reported. It remains a challenge for climate models to simulate the trends and principal modes of natural variability reported in this work.

One month experiments in July 2012 and impacts of the DA on temperature and moisture forecasts at the surface and four vertical layers, which over the western United States have been investigated. The four layers include lower troposphere (LT from 800 to 1000 hPa}, middle troposphere (MT from 400 to 800 hPa, upper troposphere (UT from 200 to 400 hPa and lower stratosphere (LS from 50 to 200 hPa. The results show that the regional GSI/WRF system is underestimating the observed temperature in the LT and overestimating in the UT and LS. The MW DA reduced the forecast bias from the MT to the LS within 30 h forecasts, and the CON DA kept a smaller forecast bias in the LT for 2-day forecasts. The largest RMS error is observed in the LT and at the surface (SFC. Compared to the CTRL, the MW DA made the most positive contribution in the UT and LS, and the CON DA mainly improved the temperature forecasts at the SFC. However, the IR DA made a negative contribution in the LT. Most of the observed humidity in the different vertical layers is overestimated in the humidity forecasts except in the UT. The smallest bias in the humidity forecast occurred at the SFC and UT. The DA experiments apparently reduced the bias from the LT to UT, especially for the IR DA experiment, but the RMS errors are not reduced in the humidity forecasts. Compared to the CTRL, the IR DA experiment has a larger RMS error in the moisture forecast although the smallest bias is found

    The question of whether a medical care unit is an appropriate tool for outpatient care has been discussed for a long time. Our aim is to investigate whether the MCU is an effective instrument for outpatient care and adequate performance-related remuneration. This retro- and prospective overview of the work included statements on legal foundations for medical care units, for reimbursement of services in medical care units, the development of medical care centres in Germany and a listing of the specific advantages and disadvantages of an MCU. This article focuses on the generally applicable facts and complements them with examples from general, visceral and vascular surgery. The main quantitative data on medical centre statistics come from different publications of the National Association of Statutory Health Insurance for Physicians. From a legal point of view the instrument MCU allows the participating of ambulatory and stationary care in the framework of medical care contracts. This has been especially extended for stationary applications, including the spectrum of possibilities that can contribute under certain circumstances for the provision of medical care in underdeveloped regions. Freelancers can benefit primarily from financial risk and minimising bureaucratic routine. The remuneration for services performed in the MCU is analogous to that of other ambulatory care providers. Basically, there are no disadvantages, but a greater design freedom and opportunities for the generation of aggregates are visible. The number of MCU in Germany has quadrupled in the last five years, indicating an establishment of an outpatient care landscape. MCU offers from the patient's perspective, providers and policy specific advantages and disadvantages. Indeed the benefits outweigh the disadvantages, but this is not yet verified by qualitative studies. The question of the appropriateness of medical care units as outpatient care instrumentation must be considered differentially

    Full Text Available This paper presents results of the study of feed quality and its effect on the performance of the fluid catalytic cracking unit using Port-Harcourt Refinery Company (PHRC as a case study. The important feed qualities used are the hydrocarbon content and a hydrotreated feed. Data on the feed properties used in PHRC were collected and a product mass balance was carried out on the fluid catalytic cracking unit. Conversion and gasoline yield of the unit were found to be 73.43 vol% and 52.07 vol% respectively. On comparison with cracking of aromatic feed, from literature, with 61.3 vol% conversion and 45.64 vol% gasoline yields, the feed is said to be paraffinic because of its higher conversion and gasoline yield. On comparison with that collected for hydrotreated feed, 80.62 vol% conversion and 63.9 vol% gasoline yield, it is concluded that feed hydrotreating increases conversion and gasoline yield by a significant amount.

  5. Application of ATOVS Microwave Radiance Assimilation to Rainfall Prediction in Summer 2004

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    Experiments are performed in this paper to understand the influence of satellite radiance data on the initial field of a numerical prediction system and rainfall prediction. First, Advanced Microwave Sounder Unit A (AMSU-A) and Unit B (AMSU-B) radiance data are directly used by three-dimensional variational data assimilation to improve the background field of the numerical model. Then, the detailed effect of the radiance data on the background field is analyzed. Secondly, the background field, which is formed by application of Advanced Television and Infrared Observation Satellite Operational Vertical Sounder (ATOVS) microwave radiance assimilation, is employed to simulate some heavy rainfall cases.The experiment results show that the assimilation of AMSU-A (B) microwave radiance data has a certain impact on the geopotential height, temperature, relative humidity and flow fields. And the impacts on the background field are mostly similar in the different months in summer. The heavy rainfall experiments reveal that the application of AMSU-A (B) microwave radiance data can improve the rainfall prediction significantly. In particular, the AMSU-A radiance data can significantly enhance the prediction of rainfall above 10 mm within 48 h, and the AMSU-B radiance data can improve the prediction of rainfall above 50 mm within 24 h. The present study confirms that the direct assimilation of satellite radiance data is an effective way to improve the prediction of heavy rainfall in the summer in China.

    Full Text Available This study aimed to investigate the kinematic and kinetic changes when resistance is applied in horizontal and vertical directions, produced by using different percentages of body weight, caused by jumping movements during a dynamic warm-up. The group of subjects consisted of 35 voluntary male athletes (19 basketball and 16 volleyball players; age: 23.4 ± 1.4 years, training experience: 9.6 ± 2.7 years; height: 177.2 ± 5.7 cm, body weight: 69.9 ± 6.9 kg studying Physical Education, who had a jump training background and who were training for 2 hours, on 4 days in a week. A dynamic warm-up protocol containing seven specific resistance movements with specific resistance corresponding to different percentages of body weight (2%, 4%, 6%, 8%, 10% was applied randomly on non consecutive days. Effects of different warm-up protocols were assessed by pre-/post- exercise changes in jump height in the countermovement jump (CMJ and the squat jump (SJ measured using a force platform and changes in hip and knee joint angles at the end of the eccentric phase measured using a video camera. A significant increase in jump height was observed in the dynamic resistance warm-up conducted with different percentages of body weight (p 0.05. In jump movements before and after the warm-up, while no significant difference between the vertical ground reaction forces applied by athletes was observed (p>0.05, in some cases of resistance, a significant reduction was observed in hip and knee joint angles (p<0.05. The dynamic resistance warm-up method was found to cause changes in the kinematics of jumping movements, as well as an increase in jump height values. As a result, dynamic warm-up exercises could be applicable in cases of resistance corresponding to 6-10% of body weight applied in horizontal and vertical directions in order to increase the jump performance acutely.

    The first of a new generation of microwave sounders was launched aboard the Suomi-National Polar-Orbiting Partnership satellite in October 2011. The Advanced Technology Microwave Sounder (ATMS) combines the capabilities and channel sets of three predecessor sounders into a single package to provide information on the atmospheric vertical temperature and moisture profiles that are the most critical observations needed for numerical weather forecast models. Enhancements include size/mass/power approximately one third of the previous total, three new sounding channels, the first space-based, Nyquist-sampled cross-track microwave temperature soundings for improved fusion with infrared soundings, plus improved temperature control and reliability. This paper describes the ATMS characteristics versus its predecessor, the advanced microwave sounding unit (AMSU), and presents the first comprehensive evaluation of key prelaunch and on-orbit performance parameters. Two-year on-orbit performance shows that the ATMS has maintained very stable radiometric sensitivity, in agreement with prelaunch data, meeting requirements for all channels (with margins of 40% for channels 1-15), and improvements over AMSU-A when processed for equivalent spatial resolution. The radiometric accuracy, determined by analysis from ground test measurements, and using on-orbit instrument temperatures, also shows large margins relative to requirements (specified as ATMS is especially important for this first proto-flight model unit of what will eventually be a series of ATMS sensors providing operational sounding capability for the U.S. and its international partners well into the next decade.

    Medication errors have long been considered critical in global health care systems. However, few studies have been conducted to explore the effects of nursing unit structure on medication errors. The purpose of this study, therefore, was to determine the effects of structural factors on medication errors in nursing units. A total of 977 staff nurses and 62 head nurses participated in this cross-sectional design study. The findings show that professional autonomy (β = .53, t = 6.03, p nursing experts (β = .52, t = 5.99, p medication error rates. This study shows that the structural factors influence medication administration and the mechanistic approach is specifically in relation of low medication error rates. The author suggests that head nurses should consider strategies that require adjustments to unit control mechanisms.

    This paper reports the development of a millimeter-wave space-borne atmospheric Temperature Sounding Unit (TSU) in Indian Space Research Organization (ISRO). This is ISRO's first leap towards millimeter-wave technology. The sensor has several new accomplishments to its credit which include among others, the philosophy of sounding channel selection, the new assortment of temperature sounding channels, simultaneous observation of both polarizations of all channels, compact dual-band scanning Gregorian reflector antenna, indigenously developed black-body target for in-orbit calibration, in-house developed millimeter-wave RF front-end and pre-detection automatic gain control method. The prime feature of this instrument is its unique set of channels which can profile the earth's atmosphere from surface to 40 km altitude with vertical resolution ranging from less than a km near surface to +/-2.5 km at 30km altitude. The channels are predominantly off-resonant frequencies in the 50―60 GHz O2 absorption spectrum which offer near-uniform attenuation and hence more channel-bandwidth and better temperature sensitivity and yet have adequate overlap of their weighting functions to achieve the desired vertical resolution. These channels are different and have fewer bands from what has been flown in all earlier sounding missions worldwide e.g. AMSU-A, SSMIS, ATMS etc. The TSU radiometer has been characterized thoroughly using ingenious methods such as low-power active RF energizing along with frequency sweep. This is a compact, low-mass, low-power instrument and has been configured for the ISRO mini-satellite (IMS-2) bus. The flight model with improved hardware performance is being built and a suitable opportunity of flying it is being explored.

    This project sought to identify factors contributing to a healthy Army National Guard (ARNG) unit. Its results were intended to contribute to a computerized forecasting model under development at Oak Ridge National Laboratory. The model, the ARNG Regional Recruiting Potential Model (RRPM), forecasts locations of successful new or modified Guard units. The study was expected to enhance the understanding of what constituents a healthy Guard unit. A Delphi approach was used to define criteria for healthy Guard units and to elicit rankings of those criteria. Two sets of telephone interviews were conducted with a sample of 102 individuals-two battalion-level administrative officers, or their equivalents, in each state in Washington, DC. During these telephone calls, the phrase unit supportability'' was used to express the notion of a healthy unit. The first set of interviews obtained background information and respondents' ideas of the criteria that lead to unit supportability and to a lack of supportability. The data were analyzed to develop a list of ten criteria for unit supportability. In the second interview, the same respondents were asked to rank those criteria in order of importance.

    This paper is a synthesis of the available literature on occupational therapy interventions performed in the adult intensive care unit (ICU). The databases of Ovid MEDLINE, Embase, the Cochrane Library, ClinicalTrials.gov and CINAHL databases were systematically searched from inception through August 2016 for studies of adults who received occupational therapy interventions in the ICU. Of 1,938 citations reviewed, 10 studies met inclusion criteria. Only one study explicitly discussed occupational therapy interventions performed and only one study specifically tested the efficacy of occupational therapy. Future research is needed to clarify the specific interventions and role of occupational therapy in the ICU and the efficacy of these interventions.

    As financial pressures drive health care to be more cost-effective and efficient, performing procedures outside the main operating room (MOR) is becoming more common. Pediatric sedation units (PSU) have proven both effective and safe at providing anesthesia for children. However, there is limited data available regarding the PSU and its potential application in pediatric otolaryngology. To evaluate the experience of performing pediatric outpatient procedures in a PSU through a parental satisfaction survey. Pediatric otolaryngology procedures performed in the PSU were prospectively recorded in a database. A prospective survey analysis was performed that measured parental satisfaction with scheduling/registration for surgery, nursing care, surgeon care, facility environment, timing/duration, and overall satisfaction. Parents completed this survey for outpatient procedures performed in either the PSU or in the MOR. The same attending surgeon was involved in all cases, with the only independent variable being the location of the surgery. Fifty surveys were collected for each group, and the surveys scores were statistically compared using nonparametric statistical analysis. Parental satisfaction was high in both the PSU and OR, with mean overall satisfaction scores of 4.8 and 4.9 (respectively) on an ordinal scale from 1 to 5. Parents reported greater clarity in preoperative information in the MOR (mean 4.8) compared to the PSU (mean 4.6) (pparents reported that MOR procedures started on time more often than those in the PSU (90-64%, pparent survey has identified education prior to surgery and timeliness of surgery as two areas to improve to meet the satisfaction standard provided by the OR.

    Electrosurgery is a popular surgical technique in which high-frequency, low-voltage electrical energy produced by an electrosurgical unit is used to excise abnormal tissue with hemostasis. In this study, electrosurgical units were critically evaluated for safety, electrical specifications, design, and performance characteristics. Quantitative electrical specification and histologic thermal artifact measurements and qualitative observations were recorded for 13 electrosurgical units representing 11 manufacturers. The Aspen Sabre 180 and Laerscope e10 were considered exemplary units based on safety criteria alone. Cut-mode thermal artifact was less than 10 microns for the Cooper Leep 6000, Laserscope e10, and Utah Finesse. A maximum fulguration distance of greater than 0.5 mm was demonstrated by the Gyne-Tech Autolepe 2000 and 4000, Laserscope e10, and the Elmed ESU 30. For gynecologic electrosurgery, the Aspen Sabre 180 and Laserscope e10 were rated best, followed closely by the Utah Finesse and Finesse II and the Gyne-Tech Autolepe 4000. Dermatologic electrosurgery may be well accomplished with many of the electrosurgical units, except as noted.

    Full Text Available Introduction: Noise pollution in hospital wards can arise from a wide range of sources including medical devices, air-conditioning systems and conversations among the staffs. Noise in intensive care units (ICUs can disrupt patients’ sleep pattern and may have a negative impact on cognitive performance. Material and methods: In this review article, we searched through PubMed and Google Scholar, using [noise and (ICU or “intensive care unit”] as keyword to find studies related to noise pollution in ICUs. In total, 250 studies were found among which 35 articles were included. Results: The majority of the reviewed studies showed that noise pollution levels were higher in ICUs than the level recommend by The United States Environmental Protection Agency and World Health Organization. Noise pollution was mostly caused by human activity and operating equipments in ICUs and other hospital wards.  Conclusion: As the results indicated, identifying, monitoring and controlling noise sources, as well as educating the hospital staffs about the negative effects of noise on patients’ health, can be highly effective in reducing noise pollution.

    Antimicrobial therapies in the Intensive Care Unit (ICU) need to be appropriate in both their antimicrobial cover and duration. We performed a prospective observational study of admissions to our semi-closed ICU over a three-month period and recorded the indications for antimicrobial therapy, agents used, duration of use, changes in therapy and reasons for changes in therapy. A change in therapy was defined as the initiation or discontinuation of an antimicrobial agent. There were 51 patients admitted during the three-month study period and all received antimicrobial therapy. There were 135 changes in antimicrobial therapy. 89 (66%) were made by the ICU team and 32 (24%) were made by the primary team. Changes were made due to a deterioration or lack of clinical response in 41 (30%) cases, due to the completion of prescribed course in 36 (27%) cases, and in response to a sensitivity result in 25 (19%) cases. Prophylactic antibiotic courses (n=24) were of a duration greater than 24 hours in 15 (63%) instances. In conclusion, the majority of changes in antimicrobial therapy were not culture-based and the duration of surgical prophylaxis was in excess of current recommended guidelines.

    Pervasive computing research is introducing new perspectives in a wide range of applications, including healthcare domain. In this study we explore the possibility to realize a prototype of a system for unobtrusive recording and monitoring of multiple biological parameters on premature newborns hospitalized in the Neonatal Intensive Care Unit (NICU). It consists of three different units: a sensitized belt for Electrocardiogram (ECG) and chest dilatation monitoring, augmented with extrinsic transducers for temperature and respiratory activity measure, a device for signals pre-processing, sampling and transmission through Bluetooth(R) (BT) technology to a remote PC station and a software for data capture and post-processing. Preliminary results obtained by monitoring babies just discharged from the ward demonstrated the feasibility of the unobtrusive monitoring on this kind of subjects and open a new scenario for premature newborns monitoring and developmental cares practice in NICU.

    1997-01-01

    Music performance provides a rich domain for study of both cognitive and motor skills. Empirical research in music performance is summarized, with particular emphasis on factors that contribute to the formation of conceptual interpretations, retrieval from memory of musical structures, and transformation into appropriate motor actions. For example, structural and emotional factors that contribute to performers' conceptual interpretations are considered. Research on the planning of musical sequences for production is reviewed, including hierarchical and associative retrieval influences, style-specific syntactic influences, and constraints on the range of planning. The fine motor control evidenced in music performance is discussed in terms of internal timekeeper models, motor programs, and kinematic models. The perceptual consequences of music performance are highlighted, including the successful communication of interpretations, resolution of structural ambiguities, and concordance with listeners' expectations. Parallels with other domains support the conclusion that music performance is not unique in its underlying cognitive mechanisms.

    Delirium is often unrecognized in ICU patients and associated with poor outcome. Screening for ICU delirium is recommended by several medical organizations to improve early diagnosis and treatment. The Confusion Assessment Method for the ICU (CAM-ICU) has high sensitivity and specificity for delirium when administered by research nurses. However, test characteristics of the CAM-ICU as performed in routine practice are unclear. To investigate the diagnostic value of the CAM-ICU in daily practice. Teams of three delirium experts including psychiatrists, geriatricians, and neurologists visited 10 ICUs twice. Based on cognitive examination, inspection of medical files, and Diagnostic and Statistic Manual of Mental Disorders, 4th edition, Text Revision criteria for delirium, the expert teams classified patients as awake and not delirious, delirious, or comatose. This served as a gold standard to which the CAM-ICU as performed by the bedside ICU-nurses was compared. Assessors were unaware of each other's conclusions. Fifteen delirium experts assessed 282 patients of whom 101 (36%) were comatose and excluded. In the remaining 181 (64%) patients, the CAM-ICU had a sensitivity of 47% (95% confidence interval [CI], 35%-58%); specificity of 98% (95% CI, 93%-100%); positive predictive value of 95% (95% CI, 80%-99%); and negative predictive value of 72% (95% CI, 64%-79%). The positive likelihood ratio was 24.7 (95% CI, 6.1-100) and the negative likelihood ratio was 0.5 (95% CI, 0.4-0.8). Specificity of the CAM-ICU as performed in routine practice seems to be high but sensitivity is low. This hampers early detection of delirium by the CAM-ICU.

    Providing high-quality care to every patient is challenging, particularly in critical care units (CCUs). However, this standard can be achieved through organizational learning. Unfortunately, the process of organizational learning in CCUs is not well understood. The objective of this study is to describe the developmental progression of a cardiac intensive care unit (CICU) to reach its current state of reliably excellent clinical performance. The method selected for this study was a learning history. A total of 43 individuals with experience working on the CICU participated in small group interviews. Participants included nurses, surgeons, unit clerks, administrators, nursing assistants, a pharmacist, a respiratory therapist, and an administrative assistant. Relevant artifacts, including unit performance data, were also gathered to complement interview data. The CICU progressed through 4 distinct developmental stages to reach its current state. The CICU's early development involved establishing psychological safety on the unit, which prepared the unit for increased accountability, improved performance, and the pursuit of reliability. The findings validate the relationship between psychological safety and organizational learning, offer insight into how CCUs become high-reliability organizations, and provide clinical leaders with guidance for achieving high reliability in their organizations. The findings also help validate the American Association of Critical-Care Nurses position that a healthy work environment is essential to achieving clinical excellence. Critical care unit teams should use these findings as a framework for collective reflection and planning to achieve their desired future. Further research is needed to validate the applicability of these findings and to continue building the evidence base for organizational learning in hospital units.

    This article deals with how an aesthetic performance is enacted and coordinated by a performance group attracting attention and engaging commuters in a public space. Multimodal interactional resources and the way they are coordinated by interactants are investigated, and include verbal and non......-verbal actions, gaze orientation, active and static interactional strategies and props. From the data investigated, it seems that the performance act is divided into different stages which each calls for different strategies: the group's initiation of the entire performance act reveals that the group stand out...... as uncoordinated and it may have a significance for whether the 'street' performers manage to stay in character or not. Once attention from commuters is obtained, a continued gaze from these commuters opens up for subsequent interaction, which then ultimately may result in the successful handing over of a card...

    Full Text Available This paper presents a theoretical and empirical analysis of the relationship between human resource management (HRM and organizational performance. Theoretically, we discuss the importance of HRM for the development of resources and its impact on business performance. Empirically, we evaluated articles published on Brazilian academic journals that addressed such relationships. The results showed a lack of studies conducted at this intersection. From the universe of 2,469 articles, only 16 (0.6% sought to relate HRM and organizational performance. We observed a dominance of isolated HR practices, which does not consider HRM as a system, and of operational performance measures, relative to financial and efficiency variables. Most studies show a positive relationship between HRM practices and performance, in line with the literature. However, we point out some methodological issues, such as the difficulty of isolating the HR practices from its context, the failure to consider the temporality of this relationship, and the comparison between companies from different industries.

    The time of admission to a hospital, especially when unplanned, has been reported as the most stressful moment of hospitalization for both parents and children (Odievre, 2001). This qualitative study explored parents and hospital staff's perceptions and experiences related to the process of admission to a pediatric unit. Focus groups, two with parents (total n = 12) and one with health care professionals (n = 6), were conducted, and content analysis inspired by Graneheim and Lundman (2004) was performed. Parents identified four categories of perceptions: 1) management of an uncertain situation at the time of admission, 2) feelings related to the child's illness, 3) parent perception of professional's performance, and 4) parent experience of their role. Health care professionals identified two categories: 1) hospital admission as a continuous care process, and 2) undertaking improvements in the admission process. A common theme emerged about the importance of parents' trust in professionals in order to build a therapeutic relationship. Findings underscore the need for strategies to improve the hospital pediatric admission process based on a parent-professional relationship of trust and confidence through continuous quality communication and support. These strategies would include providing a nurse in charge of the admission process to assure continuity of care throughout the child's hospitalization.

    The quantification of knowledge related to the terrain and the landuse/landcover of administrative units in Southern Greece (Peloponnesus) is performed from the CGIAR-CSI SRTM digital elevation model and the CORINE landuse/landcover database. Each administrative unit is parametrically represented by a set of attributes related to its relief. Administrative units are classified on the basis of K-means cluster analysis in an attempt to see how they are organized into groups and cluster derived geometric signatures are defined. Finally each cluster is parametrically represented on the basis of the occurrence of the Corine landuse/landcover classes included and thus, landcover signatures are derived. The geometric and the landuse/landcover signatures revealed a terrain dependent landuse/landcover organization that was used in the assessment of the forest fires impact at moderate resolution scale.

    The intensive care units must be prepared for a possible disaster, whether internal or external, in case it becomes necessary to evacuate the in-patients. They must have an Emergency and Self-protection Plan that includes the patient evacuation criteria and this must be known by all the personnel who work in the service. For that reason, the patients must be triaged, based on their attention priorities, according to their survival possibilities. Having an evacuation, known by all the personnel and updated by means of the performance of periodic drills, should be included as a quality indicator that must be met, since this would achieve better attention to the patient in case of a disaster situation requiring the evacuation of the ICU.

    Congestion in the postanesthesia care unit (PACU) leads to the formation of waiting queues for patients being transferred after surgery, negatively affecting hospital resources. As patients recover in the operating room, incoming surgeries are delayed. The purpose of this study was to establish the impact of this phenomenon in multiple settings. An operational mathematical study based on the queuing theory was performed. Average queue length, average queue waiting time, and daily queue waiting time were evaluated. Calculations were based on the mean patient daily flow, PACU length of stay, occupation, and current number of beds. Data was prospectively collected during a period of 2 months, and the entry and exit time was recorded for each patient taken to the PACU. Data was imputed in a computational model made with MS Excel. To account for data uncertainty, deterministic and probabilistic sensitivity analyses for all dependent variables were performed. With a mean patient daily flow of 40.3 and an average PACU length of stay of 4 hours, average total lost surgical opportunity time was estimated at 2.36 hours (95% CI: 0.36-4.74 hours). Cost of opportunity was calculated at $1592 per lost hour. Sensitivity analysis showed that an increase of two beds is required to solve the queue formation. When congestion has a negative impact on cost of opportunity in the surgical setting, queuing analysis grants definitive actions to solve the problem, improving quality of service and resource utilization.

    Adherents of performance theory emphasize the constitutive and transformative potential of rituals with respect to patterns of social organization and authority. For them, rituals “not only mean something, but also do something, particularly the way they construct and inscribe power relationships......” (Bell 1997). This contribution focuses on the role of ritual in postcolonial identity constitution and the performative authentication of political power and social authority in Taiwan. Since the middle of the 1990s, traditionalist performances have been on the rise on the island. Generously subsidized...... at the contemporary rituals of the Taroko and Ami, which are characterized by the above mentioned dynamics, I argue that rituals publicly performed by aborigines today amalgamate different levels of meaning.

    This study was undertaken to improve the performance of a Chemotherapy Treatment Unit by increasing the throughput and reducing the average patient's waiting time. In order to achieve this objective, a scheduling template has been built. The scheduling template is a simple tool that can be used to schedule patients' arrival to the clinic. A simulation model of this system was built and several scenarios, that target match the arrival pattern of the patients and resources availability, were designed and evaluated. After performing detailed analysis, one scenario provide the best system's performance. A scheduling template has been developed based on this scenario. After implementing the new scheduling template, 22.5% more patients can be served. 1. CancerCare Manitoba is a provincially mandated cancer care agency. It is dedicated to provide quality care to those who have been diagnosed and are living with cancer. MacCharles Chemotherapy unit is specially built to provide chemotherapy treatment to the cancer patients of Winnipeg. In order to maintain an excellent service, it tries to ensure that patients get their treatment in a timely manner. It is challenging to maintain that goal because of the lack of a proper roster, the workload distribution and inefficient resource allotment. In order to maintain the satisfaction of the patients and the healthcare providers, by serving the maximum number of patients in a timely manner, it is necessary to develop an efficient scheduling template that matches the required demand with the availability of resources. This goal can be reached using simulation modelling. Simulation has proven to be an excellent modelling tool. It can be defined as building computer models that represent real world or hypothetical systems, and hence experimenting with these models to study system behaviour under different scenarios.1, 2 A study was undertaken at the Children's Hospital of Eastern Ontario to identify the issues behind the long waiting

    Full Text Available Abstract Background In view of the close relationship of Portugal with African countries, particularly former Portuguese colonies, the diagnosis of malaria is not a rare thing. When a traveller returns ill from endemic areas, malaria should be the number one suspect. World Health Organization treatment guidelines recommend that adults with severe malaria should be admitted to an intensive care unit (ICU. Methods Severe cases of malaria in patients admitted to an ICU were reviewed retrospectively (1990-2011 and identification of variables associated with in-ICU mortality performed. Malaria prediction score (MPS, malaria score for adults (MSA, simplified acute physiology score (SAPSII and a score based on WHO's malaria severe criteria were applied. Statistical analysis was performed using StataV12. Results Fifty nine patients were included in the study, all but three were adults; 47 (79,6% were male; parasitaemia on admission, quantified in 48/59 (81.3% patients, was equal or greater than 2% in 47 of them (97.9%; the most common complications were thrombocytopaenia in 54 (91.5% patients, associated with disseminated intravascular coagulation (DIC in seven (11.8%, renal failure in 31 (52.5% patients, 18 of which (30.5% oliguric, shock in 29 (49.1% patients, liver dysfunction in 27 (45.7% patients, acidaemia in 23 (38.9% patients, cerebral dysfunction in 22 (37.2% patients, 11 of whom with unrousable coma, pulmonary oedema/ARDS in 22 (37.2% patients, hypoglycaemia in 18 (30.5% patients; 29 (49.1% patients presented five or more dysfunctions.

    This paper introduces a new bio-assessment tool, the mini-mobile environmental monitoring unit (MMU). The MMU is a portable, lightweight, energy-efficient, miniaturized laboratory that provides a low-flow system for on-site exposure of aquatic animals to local receiving waters in a protected, controllable environment. Prototypes of the MMU were tested twice in week-long studies conducted during the summers of 2008 and 2009, and in a 12-day study in 2010. In 2008, fathead minnows and polar organic chemical integrative samplers (POCIS) were deployed downstream from the Hastings, Nebraska wastewater treatment plant (WWTP), a waterway known to contain estrogenic contaminants in biologically active concentrations. In 2009, minnows and POCIS were deployed downstream, upstream and within the Grand Island, Nebraska WWTP, a site where the estrogenic contaminants had been detected, but were found at levels below those necessary to directly impact fish. In 2010, an advanced prototype was tested at the Sauk Center, Minnesota WWTP to compare its performance with that of traditional fish exposure methods including caged fish and static-renewal laboratory testing of effluent. Results from the prototype illustrate the capabilities of the MMU and offer an inexpensive monitoring tool to integrate the effects of pollutant sources with temporally varying composition and concentration.

    We evaluated the epidemiology of Candida bloodstream infections in the neonatal intensive care unit (NICU) of an Italian university hospital during a 9-year period as a means of quantifying the burden of infection and identifying emerging trends. Clinical data were searched for in the microbiological laboratory database. For comparative purposes, we performed a review of NICU candidemia. Forty-one candidemia cases were reviewed (overall incidence, 3.0 per 100 admissions). Candida parapsilosis sensu stricto (58.5%) and C. albicans (34.1%) were the most common species recovered. A variable drift through years was observed; in 2015, 75% of the cases were caused by non-albicans species. The duration of NICU hospitalization of patients with non-albicans was significantly longer than in those with C. albicans (median days, 10 versus 12). Patients with non-albicans species were more likely to have parenteral nutrition than those with C. albicans (96.3% versus 71.4%). Candida albicans was the dominant species in Europe and America (median, 55% and 60%; resp.); non-albicans species predominate in Asia (75%). Significant geographic variation is evident among cases of candidemia in different parts of the world, recognizing the importance of epidemiological data to facilitate the treatment.

    Sedatives are commonly used for mechanically ventilated patients in intensive care units (ICU). However, a variety of sedatives are available and their efficacy and safety have been compared in numerous trials with inconsistent results. To resolve uncertainties regarding usefulness of these sedatives, we performed a systematic review and network meta-analysis. Randomized controlled trials comparing sedatives in mechanically ventilated ICU patients were included. Graph-theoretical methods were employed for network meta-analysis. A total of 51 citations comprising 52 RCTs were included in our analysis. Dexmedetomidine showed shorter MV duration than lorazepam (mean difference (MD): 68.7; 95% CI: 18.2–119.3 hours), midazolam (MD: 10.2; 95% CI: 7.7–12.7 hours) and propofol (MD: 3.4; 95% CI: 0.9–5.9 hours). Compared with dexmedetomidine, midazolam was associated with significantly increased risk of delirium (OR: 2.47; 95% CI: 1.17–5.19). Our study shows that dexmedetomidine has potential benefits in reducing duration of MV and lowering the risk of delirium. PMID:28322337

    Full Text Available Objective: Ventilator-associated pneumonia (VAP is the most common nosocomial infection in the intensive care units (ICUs. It causes prolonged hospital stay and increases mortality. In this study, we aimed to investigate the rate of VAP, causative microorganisms, and their antibiotic susceptibilities in anaesthesiology and reanimation ICU (ARICU. Material and Method: This retrospective study included patients who were admitted to 12-bed ARICU between January 2013 and December 2014. The detection of VAP was done according to Centers for Disease Control and Prevention criteria. The rate of VAP, VAP ratio, and ventilator utilization ratio (VUR were calculated according to guidelines of Turkish National Infection Surveillance Control Group. Endotracheal aspiration samples were collected and cultivated. The identification of the isolates was performed by using VITEK-2 automated system. Antibiotic susceptibilities were determined by the disc diffusion method according to the Clinical and Laboratory Standards Institute criteria. Results: VAP was determined in 16 of 359 patients who required invasive mechanic ventilation for longer than 48 hours and hospitalized in ARICU. VUR was 65%, VAP ratio was 4.5% and the rate of VAP was 3.3 per 1000 ventilator days. Seventeen microorganisms were isolated from endotracheal aspiration samples, including Acinetobacter baumannii (n=6, Pseudomonas aeruginosa (n=4, methicillin-resistant Staphylococcus aureus (n=4, Klebsiella pneumoniae, Enterobacter cloacae and Serratia marcescens. The most sensitive antibiotics for microorganisms are listed as follows; Acinetobacter baumannii: colistin, Pseudomonas aeruginosa: amikacin, carbapenems; Methicillin-resistant Staphylococcus aureus: linezolid, teicoplanin, vancomycin, trimethoprim sulfamethoxazole; Klebsiella and Enterobacteriaceae species: carbapenems, trimethoprim sulfamethoxazole, gentamicin. Conclusion: Intermittent analyses and antibiotic susceptibilities of VAP

    During a period of 3 months an infection survey was carried out in 4 intensive care units (ICUs), 2 in Vienna, Austria, and one each in Ulm and Münster, Federal Republic of Germany, using a common protocol. A total of 329 patients was monitored prospectively. This pilot study was performed to evaluate the usefulness of parameters included in the monitoring form. It was attempted to characterize the patient populations of the four units. Mean duration of stay (1-12 days), mortality (8-26%), leading diagnosis upon admission, intubation rate (41-91%) and use of pulmonary artery catheter (12-35%) were distinctly different. The rate of patients admitted already with an infection was 9-43%, septicemia was diagnosed in up to 27% of the diseased. The rate of infection acquired in the unit was between 12 and 37%, the most frequent types were bronchopneumonia, septicemia and urinary tract infection. When septicemia patients were compared to non-septicemia patients who had been admitted for more than 3 days, it appeared that the latter stayed significantly shorter at the ICU and showed less frequently bronchopneumonia or urinary tract infection at the time of admission. Septicemia patients acquired more frequently additional infections like broncho-pneumonia or urinary tract infection while staying at the ICU. The median day of onset of septicemia was the fifth day and only in a quarter of cases diagnosis could be supported by a positive blood culture. The use of antibiotics in the 4 ICUs is compared and shows marked differences. Based upon experience with this type of infection survey a new modified protocol is introduced, which displays the time course of documented events.

    The increase in survival of children with severe diseases has led to the rise of children with chronic diseases, sometimes with lifelong disabilities. In 2008, a unit for the specific care of medically complex children (MCC) was created in Hospital La Paz. To describe the work and care activities of this Unit. Patients and methods An analysis was performed on all discharge reports of the Unit between January 2014 and July 2016. The MCC Unit has 6 beds and daily outpatient clinic. A total of 1,027 patients have been treated since the creation of the unit, with 243 from 2014. The median age was 24.2 months (IQ: 10.21-84.25). The large majority (92.59%) have multiple diseases, the most frequent chronic conditions observed were neurological (76.95%), gastrointestinal (63.78%), and respiratory diseases (61.72%). More than two-thirds (69.54%) of MCC are dependent on technology, 53.49% on respiratory support, and 35.80% on nutritional support. Hospital admission rates have increased annually. There have been 403 admissions since 2014, of which 8.93% were re-admissions within 30 days of hospital discharge. The median stay during 2014-2016 was 6 days (IQ: 3-14). The occupancy rate has been above 100% for this period. Currently, 210 patients remain on follow-up (86.42%), and 11 children (4.53%) were discharged to their referral hospitals. The mortality rate is 9.05% (22 deaths). The main condition of these 22 patients was neurological (9 patients). Infectious diseases were the leading cause of death. MCC should be treated in specialized units in tertiary or high-level hospitals. Copyright © 2016 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

    Full Text Available Abstract Background Fenoldopam mesylate is a highly selective dopamine-1 receptor agonist approved for the treatment of hypertensive emergencies that may have a role at low doses in preserving renal function in those at high risk for or with acute kidney injury (AKI. There is no data on low-dose fenoldopam in the burn population. The purpose of our study was to describe our use of low-dose fenoldopam (0.03-0.09 μg/kg/min infusion in critically ill burn patients with AKI. Methods We performed a retrospective analysis of consecutive patients admitted to our burn intensive care unit (BICU with severe burns from November 2005 through September 2008 who received low-dose fenoldopam. Data obtained included systolic blood pressure, serum creatinine, vasoactive medication use, urine output, and intravenous fluid. Patients on concomitant continuous renal replacement therapy were excluded. Modified inotrope score and vasopressor dependency index were calculated. One-way analysis of variance with repeated measures, Wilcoxson signed rank, and chi-square tests were used. Differences were deemed significant at p Results Seventy-seven patients were treated with low-dose fenoldopam out of 758 BICU admissions (10%. Twenty (26% were AKI network (AKIN stage 1, 14 (18% were AKIN stage 2, 42 (55% were AKIN stage 3, and 1 (1% was AKIN stage 0. Serum creatinine improved over the first 24 hours and continued to improve through 48 hours (p p p p = NS. Modified inotrope score and vasopressor dependency index both decreased over 48 hours (p p = 0.0012. Conclusions These findings suggest that renal function was preserved and that urine output improved without a decrease in systolic blood pressure, increase in vasoactive medication use, or an increase in resuscitation requirement in patients treated with low-dose fenoldopam. A randomized controlled trial is required to establish the efficacy of low-dose fenoldopam in critically ill burn patients with AKI.

    Propofol is not licensed for sedation in pediatric intensive care medicine mainly due to the risk of propofol infusion syndrome. Nevertheless, it is applied by many pediatric intensive care units. The aim of this national survey was to asses the current use of propofol in pediatric intensive care units in Germany. We performed a nationwide survey. The questionnaire assessed the intensive care unit type, patient numbers, dosing, duration, age and time limits, indications, side effects, and institutional protocols for propofol usage. Pediatric intensive care units in Germany. Questionnaire about routine use of propofol sent to 214 pediatric departments. None. One hundred ninety-four questionnaires (90.7%) were returned, ten had to be censored. The final analysis comprised 184 questionnaires (134 pediatric/neonatal intensive care units, 28 pediatric intensive care units, 22 neonatal intensive care units). Seventy-nine percent of intensive care units (n = 145 of 184) used propofol in children under the age of 16 yrs. Of these, 98% were for bolus application (n = 142 of 145), 78% for infusion ≥3 hrs (n = 113 of 145), and 33% for infusion >3 hrs (n = 48 of 145). A lower age limit was applied by 52% (n = 75 of 145) and a dose limit by 51% (n = 74 of 145). The median dose limit was 4 mg/kg/hr; 48% (n = 70 of 145) used 3 mg/kg/hr or less. A time limit was applied by 98% (n = 46 of 47), 70% (n = 33 of 47) used it for ≤24 hrs, and 30% (n = 15 of 47) for >24 hrs. MAIN INDICATIONS FOR PROPOFOL APPLICATION WERE: difficult sedation (44%), postoperative ventilation (43%), and difficult extubation (30%). Seven cases of propofol infusion syndrome were reported by seven centers. This study shows that propofol is used off-license by many pediatric intensive care units in Ge. The majority of users has adopted tightly controlled regimens for propofol sedation, and limits the dose to ≤3-4 mg/kg/hr and the maximum application time to 24-48 hrs.

    This study demonstrates the added benefits of assimilating the Advanced Technology Microwave Sounder (ATMS) radiances from the Suomi-NPP satellite in the NCMRWF Unified Model (NCUM). ATMS is a cross-track scanning microwave radiometer inherited the legacy of two very successful instrument namely, Advanced Microwave Sounding Unit-A (AMSU-A) and Microwave Humidity Sounder (MHS). ATMS has 22 channels: 11 temperature sounding channels around 50-60 GHz oxygen band and 6 moisture sounding channels around the 183GHz water vapour band in addition to 5 channels sensitive to the surface in clear conditions, or to water vapour, rain, and cloud when conditions are not clear (at 23, 31, 50, 51 and 89 GHz). Before operational assimilation of any new observation by NWP centres it is standard practice to assess data quality with respect to NWP model background (short-forecast) fields. Quality of all channels is estimated against the model background and the biases are computed and compared against that from the similar observations. The impact of the ATMS data on global analyses and forecasts is tested by adding the ATMS data in the NCUM Observation Processing system (OPS) and 4D-Var variational assimilation (VAR) system. This paper also discusses the pre-operational numerical experiments conducted to assess the impact of ATMS radiances in the NCUM assimilation system. It is noted that the performance of ATMS is stable and it contributes to the performance of the model, complimenting observations from other instruments.

    In this research, satellite observation data were assimilated into Weather Research and Forecasting Model (WRF) by using Three-dimensional Variational Data Assimilation System (3DVAR) to analyze its impacts on heavy rainfall forecasts. The weather case for this research was during 13-18 September 2015. Tropical cyclone VAMCO, forming in South China Sea near with Vietnam, moved on west direction to the Northeast of Thailand. After passed through Vietnam, the tropical cyclone was become to depression and there was heavy rainfall throughout the area of Thailand. Observation data, used in this research, included microwave radiance observations from the Advanced Microwave Sounding Unit-A (AMSU-A), infrared radiance observations from Infrared Atmospheric Sounding Interferometer (IASI), and GPS radio occultation (RO) from the COSMIC and CHAMP missions. The experiments were designed in five cases, namely, 1) without data assimilation (CTRL); 2) with only RO data (RO); 3) with only AMSU-A data (AMSUA); 4) with only IASI data (IASI); and 5) with all of RO, AMSU-A and IASI data assimilation (ALL). Then all experiment results would be compared with both NCEP FNL (Final) Operational Global Analysis and the observation data from Thai Meteorological Department weather stations. The experiments result demonstrated that with microwave (AMSU-A), infrared (IASI) and GPS radio occultation (RO) data assimilation can produce the positive impact on analyses and forecast. All of satellite data assimilations have corresponding positive effects in term of temperature and humidity forecasting, and the GPS-RO assimilation produces the best of temperature and humidity forecast biases. The satellite data assimilation has a good impact on temperature and humidity in lower troposphere and vertical distribution that very helpful for heavy rainfall forecast improvement.

    Full Text Available Soil collapse occurs when increased moisture causes chemical or physical bonds between the soil particles to weaken, which allows the structure of the soil to collapse. Collapsible soils are generally low-density, fine-grained combinations of clay and sand left by mudflows that have dried, leaving tiny air pockets. When the soil is dry, the cemented materials are strong enough to bond the sand particles together. When natural soil becomes wet, moisture alters the cementation structure and the soil’s strength is compromised, causing collapse or subsidence. Based on soil type and density, the potential for encountering collapsible soils throughout most of the project alignment is low. Conditions in arid and semi-arid climates like Borg El Arab, near Alexandria Egypt favor the formation of the most problematic collapsible soils. The behavior and performance of compacted sand replacement over treated collapsible soil by pre-wetting and compaction are investigated in the current study. Field investigation was performed in the form of plate loading tests conducted on compacted sand replacement over improved collapsible soil. Field plate load tests program was developed to explore the effect of compacted sand replacement thickness on collapsibility potential. Treated collapsible soil was replaced with imported cohesionless soil with variable thickness up to footing width. Results proved that the improvement of collapsible soils by sand/crushed stone replacement is possible to control/mitigate their risk potentials against sudden settlement when exposed to water. Replacement soil increases the rate and reduces the amount of footing settlement. For compacted collapsible soils, partial replacement by compacted sand/crushed stone layers decreases collapsibility potential risk. Results also, introduce the development of practical, economical and environmentally safe geochemical methods for collapsible soil stabilization and collapsible risk mitigation.

    Within the United States, close to 45 million youths between the ages of 6 and 18 participate in some form of organized sports. While recent reviews have shown the positive effects of youth sport participation on youth health, there are also several negative factors surrounding the youth sport environment. To date, a comprehensive review of the negative physical and psychological effects of organized sport on youth has not been done and little thus far has documented the effect organized sport has on other players within a family, particularly on parents and siblings. Therefore the purpose of this paper is to conduct a review of studies on the negative effects of organized sport on the youth athlete and their parents and siblings. Articles were found by searching multiple databases (Physical Education Index and Sociology, Psychology databases (Proquest), SPORTDiscus and Health, History, Management databases (EBSCOhost), Science, Social Science, Arts and Humanities on Web of Science (ISI), SCOPUS and Scirus (Elsevier). Results show the darker side of organized sport for actors within the family unit. A model is proposed to explain under which circumstances sport leads to positive versus negative outcomes, ideas for future research are drawn and recommendations are made to optimize the youth sport experience and family health.

    Vetter, J S; Worley, P

    2002-07-24

    Traditional techniques for performance analysis provide a means for extracting and analyzing raw performance information from applications. Users then reason about and compare this raw performance data to their performance expectations for important application constructs. This comparison can be tedious, difficult, and error-prone for the scale and complexity of today's architectures and software systems. To address this situation, we present a methodology and prototype that allows users to assert performance expectations explicitly in their source code using performance assertions. As the application executes, each performance assertion in the application collects data implicitly to verify the assertion. By allowing the user to specify a performance expectation with individual code segments, the runtime system can jettison raw data for measurements that pass their expectation, while reacting to failures with a variety of responses. We present several compelling uses of performance assertions with our operational prototype including raising a performance exception, validating a performance model, and adapting an algorithm to an architecture empirically at runtime.

    2017-05-01

    Pocket ultrasonography may enhance patient diagnosis and care. We sought to assess pocket ultrasound in detecting common conditions in the coronary care unit (CCU) compared to portable daily chest radiography (CXR) and conventional transthoracic echocardiography (TTE). An experienced pocket ultrasound user performed a pocket ultrasound examination for interstitial edema, pneumonia, central line seen in the right ventricle, pleural and pericardial effusions, left atrial enlargement, and cardiomegaly. Data were blindly compared to the radiologist CXR interpretation and cardiologist TTE interpretation. A total of 102 CXR and pocket ultrasound examinations were performed in 66 patients. The most common CXR indication was "interval change" (37%) and finding central line (65%). Pocket ultrasound demonstrated overall good concordance with CXR ranging from 77% for pleural effusion to 92% for pneumonia. Additionally, the pocket ultrasound examination appeared to anticipate resolution of pulmonary edema prior to the CXR. Compared to TTE, pocket ultrasound had excellent sensitivity for cardiac findings with values ranging from 85% for left atrial enlargement to 100% for cardiomegaly, but limited specificity of cardiomegaly at just 51%. In the CCU, bedside pocket ultrasound reliably diagnoses common conditions identified by CXR with the advantage of lack of ionizing radiation and the suggestion of detecting the resolution of pulmonary edema prior to CXR. Pitfalls include only modest concordance for pleural effusions and limited specificity for cardiomegaly. Larger, multicenter studies are needed to determine whether pocket ultrasound can reduce routine daily CXR in the CCU and other intensive care settings. © 2017, Wiley Periodicals, Inc.

    Composite indices are single measures that combine the strengths of two or more individual measures and provide broader, easy-to-use measures for evaluation of provider performance and comparisons across units and hospitals to support quality improvement. The study objective was to develop a unit-level inpatient composite nursing care quality performance index-the Pressure Ulcer and Fall Rate Quality Composite Index. Two-phase measure development study. 5144 patient care units in 857 United States hospitals participating in the National Database of Nursing Quality Indictors(®) during the year 2013. The Pressure Ulcer and Fall Rate Quality Composite Index was developed in two phases. In Phase 1 the formula was generated using a utility function and generalized penalty analysis. Experts with experience in healthcare quality measurement provided the point of indicator equivalence. In Phase 2 initial validity evidence was gathered based on hypothesized relationships between the Pressure Ulcer and Fall Rate Quality Composite Index and other variables using two-level (unit, hospital) hierarchical linear mixed modeling. The Pressure Ulcer and Fall Rate Quality Composite Index=100-PUR-FR, where PUR is pressure ulcer rate and FR is total fall rate. Higher scores indicate better quality. Bland-Altman plots demonstrated agreement between pairs of experts and provided evidence for inter-rater reliability of the formula. The validation process demonstrated that higher registered nurse skill mix, higher percent of registered nurses with a baccalaureate in nursing or higher degree, higher percent of registered nurses with national specialty certification, and lower percent of hours supplied by agency staff were significantly associated with higher Pressure Ulcer and Fall Rate Quality Composite Index scores. Higher percentages of unit patients at risk for a hospital-acquired pressure ulcer and higher unit rates of physical restraint use were not associated with higher Pressure

    An outbreak of carbapenem-resistant Acinetobacter baumannii (CRAb) occurred in an interdisciplinary intensive care unit, affecting 10 patients. Within hours of recognition of the spread of CRAb an intervention team was instituted for collection of available data, decision-making, communication and monitoring of all interventions performed, including cohorting, temporary stop of admissions, staff education, and enforcement of infection control measures. An area was defined for cohortation of patients colonized with CRAb, with a separate nursing team and a second set of mobile equipment. New transmissions were no longer observed after only four days into the institution of enhanced infection control measures. Copyright © 2015 The Healthcare Infection Society.

ESBL-E were found in the feces of 65 (13.6% patients in phase 2. The antimicrobial use density values (expressed as defined daily doses per 1,000 bed-days were not significantly different between the two phases for fluoroquinolones (7 vs. 10, p = 0.376, third-generation cephalosporins (24.2 vs. 29.5, p = 0.724, tazobactam/ piperacillin (44.6 vs. 57.3, p = 0.489, and carbapenems (73 vs. 55.5, p = 0.222. Moreover, there were no significant differences in ICU mortality and length of stay (11.5% vs. 9.8%, p = 0.412, and 9 vs. 10 days, p = 0.28, respectively. Conclusions Stool culture seemed ineffective in improving the antimicrobial use density of broad-spectrum antimicrobials, clinical outcomes, and ICU length of stay, and is not recommended for surveillance of ESBL-E in a non-outbreak situation.

    There has been a recent rapid growth in the number of psychology courses offered online through institutions of higher education. The American Psychological Association has highlighted the importance of ensuring the effectiveness of online psychology courses (Halonen et al., 2013). Despite this, there have been inconsistent findings regarding student grades, satisfaction, and retention in online psychology units. Equivalency Theory (Simonson, 1999; Simonson et al., 1999) posits that online and classroom-based learners will attain equivalent learning outcomes when equivalent learning experiences are provided. We present a study of an online introductory psychology unit designed to provide equivalent learning experiences to the pre-existing face-to-face version of the unit. Using quasi-experimental methods, academic performance, student feedback, and retention data from 866 Australian undergraduate psychology students were examined to assess whether the online unit developed to provide equivalent learning experiences produced comparable outcomes to the ‘traditional’ unit delivered face-to-face. Student grades did not significantly differ between modes of delivery, except for a group-work based assessment where online students performed more poorly. Student satisfaction was generally high in both modes of the unit, with group-work the key source of dissatisfaction in the online unit. The results provide partial support for Equivalency Theory. The group-work based assessment did not provide an equivalent learning experience for students in the online unit highlighting the need for further research to determine effective methods of engaging students in online group activities. Consistent with previous research, retention rates were significantly lower in the online unit, indicating the need to develop effective strategies to increase online retention rates.

    Full Text Available Abstract Background Health systems in low and middle income countries are struggling to improve efficiency in the functioning of health units of which workforce is one of the most critical building blocks. In India, Rogi Kalyan Samiti (RKS was established at every health unit as institutions of local decision making in order to improve productive efficiency and quality. Measuring efficiency of health units is a complex task. This study aimed at assessing the perception (opinion and satisfaction of health workers about influence of RKS on improving efficiency of peripheral decision making health units (DMHU; examining differences between priority and non-priority set-ups; identifying predictors of satisfaction at work; and discussing suggestions to improve performance. Methods Following a cross-sectional, comparative study design, 130 health workers from 30 institutions were selected through a multi-stage stratified random sampling. A semi-structured questionnaire was administered to assess perception and opinion of health workers about influence of RKS on efficiency of decision making at local level, motivation and performance of staff, and availability of funds; improvement of quality of services, and coordination among co-workers; and participation of community in local decision making. Three districts with highest infant mortality rate (IMR, one each, from 3 zones of Odisha and 3 with lowest IMR were selected on the basis of IMR estimates of 2011. The former constituted priority districts (PD and the latter, non-priority districts (NPD. Composite scores were developed and compared between PD and NPD. Adjusted linear regression was conducted to identify predictors of satisfaction at work. Results A majority of respondents felt that RKS was efficient in decision making that resulted in improvement of all critical parameters of health service delivery, including quality; this was significantly higher in PD. Further, higher proportion of

    Full Text Available This paper argues for the inclusion of surgery within the canon of performance science. The world of medicine presents rich, complex but relatively under-researched sites of performance. Performative aspects of clinical practice are overshadowed by a focus on the processes and outcomes of medical care, such as diagnostic accuracy and the results of treatment. The primacy of this ‘clinical’ viewpoint - framed by clinical professionals as the application of medical knowledge - hides resonances with performance in other domains. Yet the language of performance is embedded in the culture of surgery - surgeons ‘perform’ operations, work in an operating ‘theatre’ and use ‘instruments’. This paper asks what might come into view if we take this performative language at face value and interrogate surgery from the perspective of performance science. It addresses the following questions: 1.To what extent and in what ways can surgical practice (both consultation and operation be considered as performance?2.How does comparison with two domains domains of non-surgical performance (close-up magic and puppetry illuminate understanding of surgical practice as performance?3.In what ways might including surgery within the canon of performance studies enrich the field of performance science?Two detailed case studies over 5 years with magicians (71.5 hours contact time and puppeteers (50.5 hours contact time identified performative aspects of surgical practice from the perspectives of professionals (as individuals or in groups and audiences. Physical simulation provided a means for non-clinicians to access and experience elements of the surgical world, acting as a prompt for discussion. Thematic analysis was used to establish themes and sub-themes.Key themes were: 1 clinical consultation can be viewed as ‘close-up live performance with a very small audience’ and 2 operative surgery can be viewed as ‘reading bodies within a dextrous team

    Infill drilling of wells on a uniform spacing, without regard to reservoir performance and characterization, must become a process of the past. Such efforts do not optimize reservoir development as they fail to account for the complex nature of reservoir heterogeneities present in many low permeability carbonate reservoirs. New and emerging technologies such as cross-borehole tomography, geostatistical modeling, and rigorous decline type curve analysis can be used to quantify reservoir quality and the degree of interwell communication. These results can be used to develop a 3-D simulation model for prediction of infill locations. In this work, the authors will demonstrate the application of reservoir surveillance techniques to identify additional reservoir ``pay`` zones, and to monitor pressure and preferential fluid movement in the reservoir. These techniques are: long-term production and injection data analysis, pressure transient analysis, and advanced open and cased hole well log analysis. The major contribution of this paper is the summary of cost effective reservoir characterization and management tools that will be helpful to both independent and major operators for the optimal development of heterogeneous, low permeability carbonate reservoirs such as the North Robertson (Clearfork) Unit.

    A series of metal free Tetrathienoacene-based (TTA-based) organic dyes are designed and investigated as sensitizers for application in dye sensitized solar cells (DSSCs). Density function theory and time dependent density function theory calculations were performed on these dyes at vacuum and orthodichlorobenzene as the solvent. Effects of changing π-conjugation bridges and different functional groups in acceptor and donor units were investigated. UV-Vis absorption spectra were simulated to show the wavelength shifting and absorption properties. Inserting nitro and acyl chloride functional groups in acceptor and NH2 in donor units leads to the reduction of HOMO-LUMO gap by lowering the lowest unoccupied molecular orbital (LUMO) energy level and raising the highest occupied molecular orbital (HOMO) energy level and the increase in effective parameters in DSSC' efficiency. The results show that changing spacer units from thiophene to furan has a great effect on electronic structure and absorption spectra. Investigation of the electron distributions of frontier orbitals shows the HOMO and LUMO localization in donor and acceptor, respectively. Some key parameters that were studied here include light harvesting efficiency, free energy of electron injection and open circuit photo-voltage.

    A multicentre study in five postanaesthesia care units (PACUs) was performed to investigate patient and staff opinion of a specially designed music environment (DME), related to geographical location. Patients (325) and staff (91) described their opinion by means of a questionnaire-anonymously in the case of staff. Patients were not asked beforehand for permission to play music. Amongst patients 267 (83%) found the sound environment with DME pleasant or very pleasant, 26 (6%) found it unpleasant, whereas 32 (11%) answered "no opinion". The opinion of the patients did not differ significantly with geographical location. A strong correlation (P<0.05) between a positive attitude towards DME and degree of relaxation and satisfaction with stay was found. The staff had an equally positive attitude towards the DME; but theirs varied significantly with location. The opinion of the staff was more similar concerning the beneficial effect on working conditions and distress, but varied still significantly. The opinion of the staff had no demonstrable impact on that of the patients.

    Pressure injuries (PIs) create a significant burden in the health care system. Up to 49% of critically ill patients develop PIs. Identifying and understanding potential risk factors is essential to the provision of effective targeted prevention strategies to mitigate risk. The objectives of this review are to identify patient-centred clinical factors that may be associated with PI development in the adult intensive care environment and to determine the effect size of the relationship between identified factors and PI development in this unique population. The review will follow the PRISMA reporting guidelines for systematic reviews. Electronic databases (Cochrane; PubMed/MEDLINE; CINAHL (EBSCOhost); Embase; Scopus; PsycINFO; Proquest; Networked Digital Library of Theses and Dissertations; Australian Digital Theses Program, Grey literature, Google scholar, and Clinical Trial Registries) will be systematically searched. A suite of search terms will identify articles that have examined the patient-centred risk factors for PI development in adult intensive care units. The search strategy will be designed to retrieve studies published since inception to 2016 in English language. Quality of the studies will be assessed by using an assessment framework designed to appraise quality in prognostic studies and methodological considerations in the analysis and publication of observational studies. Screening, study selection process, and data extraction will be undertaken by two independent reviewers. Disagreement will be resolved by discussion and, if required, a third independent reviewer. Clinical and methodological heterogeneity across studies will be assessed and, if possible, meta-analyses will be performed. The evidence synthesis arising from this review will identify person-centred risk factors that are associated with PI development among critically ill patients in intensive care. Findings from this review will demonstrate potential patient risk factors that may

    Full Text Available Abstract Background The incidence of fungal healthcare-associated infection (HAI has increased in a major teaching hospital in the northern part of Taiwan over the past decade, especially in the intensive care units (ICUs. The purpose of this study was to determine the factors that were responsible for the outbreak and trend in the ICU. Methods Surveillance fungal cultures were obtained from “sterile” objects, antiseptic solutions, environment of infected patients and hands of medical personnel. Risk factors for comparison included age, gender, admission service, and total length of stay in the ICU, Acute Physiology and Chronic Health Evaluation (APACHE II scores at admission to the ICU, main diagnosis on ICU admission, use of invasive devices, receipt of hemodialysis, total parenteral nutrition (TPN use, history of antibiotic therapy before HAI or during ICU stay in no HAI group, and ICU discharge status (ie, dead or alive. Univariable analysis followed by multiple logistic regression analysis was performed to identify the independent risk factors for ICU fungal HAIs and ICU mortality.

    Full Text Available The purpose of this paper is to explore the New Testament as performance literature. Recent scholarship has brought to the fore the importance of interpreting the New Testament in the context of the oral cultures of the first century. This leads us to ask about the oral/performance dynamics of the “writings” now in the New Testament canon. The paper is comprised of three parts. Part 1 offers some reasons why the New Testament writings, if they are to be appropriately interpreted in their original oral context, must be treated as performance literature. Part 2 outlines performance criticism as a methodology for this task—constructing first-century scenarios of performance as a context for interpretation, reorienting and expanding methodological approaches to the New Testament as oral literature, and employing contemporary performance as a research tool. Part 3 represents the bulk of the paper, laying out in detail the idea of performance as research, arguing that what we can learn from contemporary performances may help us interpret the New Testament writings in the context of the oral cultures of the first century.

    The beneficial effect of corticosteroids has been well established, particularly in patients free of infection with the human immunodeficiency virus. In intensive care units, the high risks of infection to which patients are exposed specifically could offset the neurological benefit of corticosteroids. The purpose of the study was to assess the effects of corticosteroids in adult patients with tuberculous meningitis admitted to intensive care unit. Retrospective cohort study including all adult patients admitted to intensive care unit for tuberculous meningitis between January 1993 and December 2005. A propensity score case matching was performed using a multivariable logistic regression model, and matched pairs were examined for baseline characteristics and outcome by using conditional regression model. A multivariate Cox's proportional hazard model was used to assess the effects of corticosteroids in all patients adjusting for propensity score. The primary outcome was mortality at 60 days and the secondary outcome was the density of incidence of nosocomial infections. Two hundred and seventy patients were included. The mean age was 38+/-17 years, and the Glasgow coma scale was 12+/-3. The overall mortality was 43.3%. Ninety-four patients who had received corticosteroids were matched to 94 patients untreated with corticosteroids by the propensity score. The baseline characteristics were similar in the two groups except for hydrocephalus, which was more frequent in the group corticosteroids. The mortality rate was 47.9% in group Corticosteroids and 52.1% in group No corticosteroids (P=0.77). The case fatality rate in stage III patients, according to the British Medical Research Council criteria, was 61.5% in the group Corticosteroids versus 74.1% in the group No corticosteroids (P=0.33). Nosocomial infections were observed in 19.1 by 1000 days patient in group Corticosteroids versus 16.1 by 1000 days patient in group No corticosteroids (P=0.4). The outcome in all

    Background Stroke is a major cause of disability in older adults, but the evidence around post-acute treatment is limited and heterogeneous. We aimed to identify profiles of older adult stroke survivors admitted to intermediate care geriatric rehabilitation units. Methods We performed a cohort study, enrolling stroke survivors aged 65 years or older, admitted to 9 intermediate care units in Catalonia-Spain. To identify potential profiles, we included age, caregiver presence, comorbidity, pre-stroke and post-stroke disability, cognitive impairment and stroke severity in a cluster analysis. We also proposed a practical decision tree for patient’s classification in clinical practice. We analyzed differences between profiles in functional improvement (Barthel index), relative functional gain (Montebello index), length of hospital stay (LOS), rehabilitation efficiency (functional improvement by LOS), and new institutionalization using multivariable regression models (for continuous and dichotomous outcomes). Results Among 384 patients (79.1±7.9 years, 50.8% women), we identified 3 complexity profiles: a) Lower Complexity with Caregiver (LCC), b) Moderate Complexity without Caregiver (MCN), and c) Higher Complexity with Caregiver (HCC). The decision tree showed high agreement with cluster analysis (96.6%). Using either linear (continuous outcomes) or logistic regression, both LCC and MCN, compared to HCC, showed statistically significant higher chances of functional improvement (OR = 4.68, 95%CI = 2.54–8.63 and OR = 3.0, 95%CI = 1.52–5.87, respectively, for Barthel index improvement ≥20), relative functional gain (OR = 4.41, 95%CI = 1.81–10.75 and OR = 3.45, 95%CI = 1.31–9.04, respectively, for top Vs lower tertiles), and rehabilitation efficiency (OR = 7.88, 95%CI = 3.65–17.03 and OR = 3.87, 95%CI = 1.69–8.89, respectively, for top Vs lower tertiles). In relation to LOS, MCN cluster had lower chance of shorter LOS than LCC (OR = 0.41, 95%CI = 0.23–0

    Full Text Available Patients with idiopathic inflammatory myopathies (IIMs are sometimes complicated with life-threatening conditions requiring intensive care unit (ICU admission. In the past, owing to the low incidence of IIM, little was known about such patients. Our aim was to investigate the clinical features and outcomes of these patients and identify their risk factors for mortality.A retrospective study was performed of IIM patients admitted over an 8-year period to the medical ICU of a tertiary referral center in China. We collected data regarding demographic features, IIM-related clinical characteristics, reasons for admission, organ dysfunction, and outcomes. Independent predictors of ICU mortality were identified through multivariate logistic regression analysis.Of the 102 patients in our cohort, polymyositis (PM, dermatomyositis (DM, and clinically amyopathic dermatomyositis (CADM accounted for 23.5%, 64.7%, and 11.7% respectively. The median duration from the onset of IIM to ICU admission was 4.3 months (interquartile range [IQR], 2.6-9.4 months. Reasons for ICU admission were infection alone (39.2%, acute exacerbation of IIM alone (27.5%, the coexistence of both (27.5%, or other reasons (5.8%. Pneumonia accounted for 97% of the infections; 63.2% of infections with documented pathogens were caused by opportunistic agents. Rapid progressive interstitial lung disease (RP-ILD was responsible for 87.5% of acute exacerbation of IIM. The median Acute Physiology and Chronic Health Evaluation II (APACHE II score on ICU day 1 was 17 (IQR 14-20. On ICU admission, acute respiratory failure (ARF was the most common type (80.4% of organ failure. The mortality rate in the ICU was 79.4%. Factors associated with increased ICU mortality included a diagnosis of DM (including CADM, a high APACHE II score, the presence of ARF, a decreased PaO2/FiO2 ratio, and a low lymphocyte count at the time of ICU admission.The outcome of IIM patients admitted to the ICU was extremely

    Objectives. The goal of the study was to improve prediction of longitudinal flight simulator performance by studying cognitive factors that may moderate the influence of chronological age. Method. We examined age-related change in aviation performance in aircraft pilots in relation to baseline cognitive ability measures and aviation expertise. Participants were aircraft pilots (N = 276) aged 40–77.9. Flight simulator performance and cognition were tested yearly; there were an average of 4.3 (± 2.7; range 1–13) data points per participant. Each participant was classified into one of the three levels of aviation expertise based on Federal Aviation Administration pilot proficiency ratings: least, moderate, or high expertise. Results. Addition of measures of cognitive processing speed and executive function to a model of age-related change in aviation performance significantly improved the model. Processing speed and executive function performance interacted such that the slowest rate of decline in flight simulator performance was found in aviators with the highest scores on tests of these abilities. Expertise was beneficial to pilots across the age range studied; however, expertise did not show evidence of reducing the effect of age. Discussion. These data suggest that longitudinal performance on an important real-world activity can be predicted by initial assessment of relevant cognitive abilities. PMID:21586627

    Our culture seems to be endlessly fascinated with its stars in entertainment, athletics, politics, and business, and holds fast to the idea that extraordinary talent accounts for an individual's extraordinary performance. At first glance, managing a star performer in your medical practice may seem like it would be an easy task. However, there's much more to managing a star performer than many practice managers realize. The concern is how to keep the star performer happy and functioning at a high level without detriment to the rest of the medical practice team. This article offers tips for practice managers who manage star performers. It explores ways to keep the star performer motivated, while at the same time helping the star performer to meld into the existing medical practice team. This article suggests strategies for redefining the star performer's role, for holding the star performer accountable for his or her behavior, and for coaching the star performer. Finally, this article offers practical tips for keeping the star performer during trying times, for identifying and cultivating new star performers, and for managing medical practice prima donnas.

    Traditionally, the performance of adaptive antenna systems is measured using automated antenna array pattern measuring equipment. This measurement equipment produces a plot of the receive gain of the antenna array as a function of angle. However, communications system users more readily accept and understand bit error rate (BER) as a performance measure. The work reported on here was conducted to characterize adaptive antenna receiver performance in terms of overall communications system performance using BER as a performance measure. The adaptive antenna system selected for this work featured a linear array, least mean square (LMS) adaptive algorithm and a high speed phase shift keyed (PSK) communications modem.

  18. Untangling Performance from Success

    CERN Document Server

    Yucesoy, Burcu

    2015-01-01

    Fame, popularity and celebrity status, frequently used tokens of success, are often loosely related to, or even divorced from professional performance. This dichotomy is partly rooted in the difficulty to distinguish performance, an individual measure that captures the actions of a performer, from success, a collective measure that captures a community's reactions to these actions. Yet, finding the relationship between the two measures is essential for all areas that aim to objectively reward excellence, from science to business. Here we quantify the relationship between performance and success by focusing on tennis, an individual sport where the two quantities can be independently measured. We show that a predictive model, relying only on a tennis player's performance in tournaments, can accurately predict an athlete's popularity, both during a player's active years and after retirement. Hence the model establishes a direct link between performance and momentary popularity. The agreement between the performa...

This complex and relative performance could be due to such things as product innovation, management quality, work organization, some other factors can be a cause even if they are not directly observed by the researcher. The critical need for the management individuals/group to continuously improve their firm/company’s efficiency and effectiveness, the need for the managers to know which are the success factors and the competitiveness determinants determine consequently, what performance measures are most critical in determining their firm’s overall success. Benchmarking, when done properly, can accurately identify both successful companies and the underlying reasons for their success. Innovation and benchmarking firm level performance are critical interdependent activities. Firm level variables, used to infer performance, are often interdependent due to operational reasons. Hence, the managers need to take the dependencies among these variables into account when forecasting and benchmarking performance. This paper studies firm level performance using financial ratio and other type of profitability measures. It uses econometric models to describe and then propose a method to forecast and benchmark performance.

  20. Managing employee performance.

    Science.gov (United States)

    McConnell, Charles R

    2004-01-01

    Performance management consists of significantly more than periodic evaluation of performance. It is the art and science of dealing with employees in a manner intended to positively influence their thinking and behavior to achieve a desired level of performance. It is essential for the manager to always model positive behavior concerning performance; what one does or says as a manager always has an influence on others. The kinds of employee behavior most likely encountered relative to performance management efforts stem from resistance to change and lack of complete understanding of what is expected. Employee participation must be elicited whenever possible for performance improvement; as far as the inner working details of a specific job are concerned, there is no one who knows the job better than the person who does it everyday. For each task to be done, an employee needs to know what output is expected, how this output will be measured, and what standards are applied in assessing the output. Managing employee performance requires ongoing contact with each employee, regular feedback, and whatever coaching, counseling, and training are necessary to bring an employee back on track when a problem appears. Sustaining efficient and effective employee performance requires the manager's ongoing attention and involvement.

    In a previous study we demonstrated that listening to a pleasant music while performing an academic test helped students to overcome stress, to devote more time to more stressful and more complicated task and the grades were higher. Yet, there remained ambiguities as for the causes of the higher test performance of these students: do they perform better because they hear music during their examinations, or would they perform better anyway because they are more gifted/motivated? This motivated the current study as a preliminary step toward that general question: Do students who like/perform music have better grades than the others? Our results confirmed this hypothesis: students studying music have better grades in all subjects.

  12. Professional performance in school

    Rubio, J. F.

    2012-01-01

    Full Text Available Professional performance in education is now calling the attention of researcher due to its role in the professionalizing process intended to increase international education standards. In this article the term professional performance is examined from the two socio-historic traditional roles involved in training the individuals as a bio-psychic and social entity: teachers and executive. By means of scientific methods, the author gives the theoretical grounds connecting professional performance, learning and individual capacity of using them in solving problem at his labor position. The professional performance is regarded as a human value that stimulates the activity. By predicting educational alternatives, the paper portraits a model of professional performance in education, referring the necessary actions needed for achieving the goals of education. Searching and discussing such alternatives leads to reinterpret professional problems and to find out ways of improving educational standards.

  13. Listening to Musical Performers

    Directory of Open Access Journals (Sweden)

    Aron Edidin

    2016-01-01

    Full Text Available In the philosophy of music and in musicology, apart from ethnomusicology, there is a long tradition of focus on musical compositions as objects of inquiry. But in both disciplines, a body of recent work focuses on the place of performance in the making of music. Most of this work, however, still takes for granted that compositions, at least in Western art music, are the primary objects of aesthetic attention. In this paper I focus on aesthetic attention to the performing activity itself. I begin by roughly characterizing what is involved in attending to the performing activity of musical performers. I then argue that such attention is essential to the full appreciation of the central compositions of the Western art music canon. Finally, I argue that, often enough, recordings provide a suitable vehicle for this sort of attention; listeners to recordings can use them to listen to musical performance.

  14. Caffeine and Performance.

    Science.gov (United States)

    Yarnell, Angela M; Deuster, Patricia A

    The role of caffeine in enhancing performance has been studied for years, and there is no doubt that caffeine can be performance enhancing. Also, a wealth of information allows for an interesting distinction between physical and cognitive performance. Most adults in America consume moderate doses of caffeine in various forms on a daily basis as caffeine is typically found in coffee, tea, soft drinks, dietary supplements, energy drinks, energy shots, and chocolate, as well as over-the-counter pills and gums. Although caffeine is readily available and widely consumed, when using it to enhance performance, a few factors should be considered. The authors discuss caffeine use among Servicemembers, its properties and effects on physical and cognitive performance, how to use it to optimize performance, and, finally, some of safety and regulatory considerations. The bottom line is that all individuals do not respond the same way to caffeine and their response depends on how the body uses and breaks down caffeine. Thus, as a user, you should monitor your own responses and performance changes when using caffeine based on the general recommendations provided. 2016.

  15. Precision performance lamp technology

    Bell, Dean A.; Kiesa, James E.; Dean, Raymond A.

    1997-09-01

    A principal function of a lamp is to produce light output with designated spectra, intensity, and/or geometric radiation patterns. The function of a precision performance lamp is to go beyond these parameters and into the precision repeatability of performance. All lamps are not equal. There are a variety of incandescent lamps, from the vacuum incandescent indictor lamp to the precision lamp of a blood analyzer. In the past the definition of a precision lamp was described in terms of wattage, light center length (LCL), filament position, and/or spot alignment. This paper presents a new view of precision lamps through the discussion of a new segment of lamp design, which we term precision performance lamps. The definition of precision performance lamps will include (must include) the factors of a precision lamp. But what makes a precision lamp a precision performance lamp is the manner in which the design factors of amperage, mscp (mean spherical candlepower), efficacy (lumens/watt), life, not considered individually but rather considered collectively. There is a statistical bias in a precision performance lamp for each of these factors; taken individually and as a whole. When properly considered the results can be dramatic to the system design engineer, system production manage and the system end-user. It can be shown that for the lamp user, the use of precision performance lamps can translate to: (1) ease of system design, (2) simplification of electronics, (3) superior signal to noise ratios, (4) higher manufacturing yields, (5) lower system costs, (6) better product performance. The factors mentioned above are described along with their interdependent relationships. It is statistically shown how the benefits listed above are achievable. Examples are provided to illustrate how proper attention to precision performance lamp characteristics actually aid in system product design and manufacturing to build and market more, market acceptable product products in the

    2001-12-01

    Evidence suggests that the effect of fasting on performance is not uniform, but it is dependent on the basal nutritional status of the subject. Breakfast consumption has a short-term effect in improving selected learning skills, especially work memory. School breakfast programmes have a positive effect on the nutritional status of children, on school attendance and probably on dropout rates. The effect of breakfast consumption on school performance depends on the interaction between the programme, student characteristics (malnutrition) and school organisation. Unless the school setting guarantees a minimum quality standard, the benefits of breakfast consumption will not be evident in performance in complex areas like language or maths.

    This paper provides a critical analysis of New Zealand's Performance Based Research Fund (PBRF). The first section sketches the development and implementation of the PBRF. The second section evaluates the scheme, concentrating on three themes: the relationship between privatization, competition and research performance; the standardization of research; and motivations for research. The paper acknowledges the thorough work completed by the Tertiary Education Advisory Commission and other policy groups in laying the foundation for the adoption of performance-based research funding in New Zealand. It is argued, however, that when viewed in its larger context, the PBRF constitutes a continuation of neoliberal trends already well established in New Zealand's tertiary education system.

    The importance of the performance of threads libraries is growing as clusters of shared memory machines become more popular POSIX threads, or Pthreads, is an industry threads library standard. We have implemented the first Pthreads benchmark suite. In addition to measuring basic thread functions, such as thread creation, we apply the L.ogP model to standard Pthreads communication mechanisms. We present the results of our tests for several hardware platforms. These results demonstrate that the performance of existing Pthreads implementations varies widely; parts of nearly all of these implementations could be further optimized. Since hardware differences do not fully explain these performance variations, optimizations could improve the implementations. 2. Incorporating Threads Benchmarks into SKaMPI is an MPI benchmark suite that provides a general framework for performance analysis [7]. SKaMPI does not exhaustively test the MPI standard. Instead, it

  13. Measures of rowing performance.

    Smith, T Brett; Hopkins, Will G

    2012-04-01

    Accurate measures of performance are important for assessing competitive athletes in practi~al and research settings. We present here a review of rowing performance measures, focusing on the errors in these measures and the implications for testing rowers. The yardstick for assessing error in a performance measure is the random variation (typical or standard error of measurement) in an elite athlete's competitive performance from race to race: ∼1.0% for time in 2000 m rowing events. There has been little research interest in on-water time trials for assessing rowing performance, owing to logistic difficulties and environmental perturbations in performance time with such tests. Mobile ergometry via instrumented oars or rowlocks should reduce these problems, but the associated errors have not yet been reported. Measurement of boat speed to monitor on-water training performance is common; one device based on global positioning system (GPS) technology contributes negligible extra random error (0.2%) in speed measured over 2000 m, but extra error is substantial (1-10%) with other GPS devices or with an impeller, especially over shorter distances. The problems with on-water testing have led to widespread use of the Concept II rowing ergometer. The standard error of the estimate of on-water 2000 m time predicted by 2000 m ergometer performance was 2.6% and 7.2% in two studies, reflecting different effects of skill, body mass and environment in on-water versus ergometer performance. However, well trained rowers have a typical error in performance time of only ∼0.5% between repeated 2000 m time trials on this ergometer, so such trials are suitable for tracking changes in physiological performance and factors affecting it. Many researchers have used the 2000 m ergometer performance time as a criterion to identify other predictors of rowing performance. Standard errors of the estimate vary widely between studies even for the same predictor, but the lowest

    2005-11-01

    Education is one of the most important aspects of human resource development. Poor school performance not only results in the child having a low self-esteem, but also causes significant stress to the parents. There are many reasons for children to under perform at school, such as, medical problems, below average intelligence, specific learning disability, attention deficit hyperactivity disorder, emotional problems, poor socio-cultural home environment, psychiatric disorders and even environmental causes. The information provided by the parents, classroom teacher and school counselor about the child's academic difficulties guides the pediatrician to form an initial diagnosis. However, a multidisciplinary evaluation by an ophthalmologist, otolaryngologist, counselor, clinical psychologist, special educator, and child psychiatrist is usually necessary before making the final diagnosis. It is important to find the reason(s) for a child's poor school performance and come up with a treatment plan early so that the child can perform up to full potential.

    The optimization of the Athena mission, the ESA's large X-ray observatory for 2028, is a key challenge. Critical elements for achieving the scientific performances are obviously the two instruments and the optics. However, additional aspects related to the overall mission performances are crucial as well, including the particle background environment (separate presentation), the calibration, the response time to Target of Opportunity requests, the functionality of the science ground segment, and the available high-quality data analysis tools. In addition, the full performance of the satellite will be modeled by an end-to-end simulator. In this presentation we will give an overview of the various systems and also present the Mock Observing Plan that is used to optimize the mission. The work presented in this contribution is based on a collective effort of the Athena science community and is coordinated by the Athena Mission Performance Working Group.

    Full Text Available Faced with the perceived need to redefine education for more economic utilitarian purposes, as well as to encourage compliance with government policies, Australia, like many other Anglophone nations, has engaged in numerous policy shifts resulting in performativity practices becoming commonplace in the educational landscape. A series of interviews with teachers from Queensland, Australia, in which they revealed their experiences of professionalism are examined archaeologically to reveal how they enact their roles in response to this performative agenda. Findings suggest that while there is some acceptance among teachers of the performative discourse, there is increasing resistance, which permits the construction of alternative or counter-discourses to the currently internationally pervasive performative climate.

    2014-02-01

    Full Text Available Orientation: Employees are a source of competitive advantage for organisations and human resource management seek to promote employee efficiency. One of the tools organisations utilise to achieve this goal is performance appraisals.Research purpose: The purpose of this study was to investigate the weaknesses in performance appraisal and to determine whether it is politicised in the North West Department of Health and Social Development in South Africa.Motivation for study: Many organisations either ignore the existence of politics in the appraisal process or assume that its impact can be minimised if they refine their appraisal instruments. Executives admit that, in appraising others, they often intentionally avoid meeting the goal of accuracy in favour of achieving goals that have more to do with exercising discretion and maintaining departmental effectiveness. Ironically, these same executives lament that the appraisals they receive often do not accurately represent their abilities and performance (Gioia & Longenecker, 1994.Research approach, design and method: Self-administered questionnaires were used as a means of collecting data and analysis was done through the use of the Statistical Package for the Social Sciences (SPSS.Main findings: The results of the study showed that respondents believe that performance appraisals are highly politicised.Practical/managerial implications: If used effectively, performance appraisals may improve employee productivity and efficiency as well as motivation and performance. However, if performance appraisal is perceived as unfair and political, it can diminish rather than enhance employee attitudes and performance.Contribution: Amongst others, it is recommended that managers should consider separating assessment for development and assessment for rewards.

  8. RAJA Performance Suite

    2017-09-01

    The RAJA Performance Suite is designed to evaluate performance of the RAJA performance portability library on a wide variety of important high performance computing (HPC) algorithmic lulmels. These kernels assess compiler optimizations and various parallel programming model backends accessible through RAJA, such as OpenMP, CUDA, etc. The Initial version of the suite contains 25 computational kernels, each of which appears in 6 variants: Baseline SequcntiaJ, RAJA SequentiaJ, Baseline OpenMP, RAJA OpenMP, Baseline CUDA, RAJA CUDA. All variants of each kernel perform essentially the same mathematical operations and the loop body code for each kernel is identical across all variants. There are a few kernels, such as those that contain reduction operations, that require CUDA-specific coding for their CUDA variants. ActuaJ computer instructions executed and how they run in parallel differs depending on the parallel programming model backend used and which optimizations are perfonned by the compiler used to build the Perfonnance Suite executable. The Suite will be used primarily by RAJA developers to perform regular assessments of RAJA performance across a range of hardware platforms and compilers as RAJA features are being developed. It will also be used by LLNL hardware and software vendor panners for new defining requirements for future computing platform procurements and acceptance testing. In particular, the RAJA Performance Suite will be used for compiler acceptance testing of the upcoming CORAUSierra machine {initial LLNL delivery expected in late-2017/early 2018) and the CORAL-2 procurement. The Suite will aJso be used to generate concise source code reproducers of compiler and runtime issues we uncover so that we may provide them to relevant vendors to be fixed.

    The practice of project management has gained enormous importance over the past several years in various business industries. “In industries as diverse as pharmaceuticals, software, and aerospace, projects drive business” (Wheatley). This gain of importance can be attributed to the magnitude of the impact project performance results in terms of time, cost, and scope have over the project performing entity. “On the basis of data released by the Bureau of Economic Analysis, part of the US De...

    The sharing economy converges around activities facilitated through digital platforms that enable peer-to-peer access to goods and services. It constitutes an apparent paradox, framed as both part of the capitalist economy and as an alternative. This duplicity necessitates focusing on the performances of the sharing economy: how it simultaneously constructs diverse economic activities whilst also inviting the deconstruction of ongoing practices of dominance. Such performances hold open the qu...

    B and W Protec, Inc. (BWP) is responsible for implementing the Performance Assurance Program for the Project Hanford Management Contract (PHMC) in accordance with DOE Order 470.1, Safeguards and Security Program (DOE 1995a). The Performance Assurance Program applies to safeguards and security (SAS) systems and their essential components (equipment, hardware, administrative procedures, Protective Force personnel, and other personnel) in direct support of Category I and H special nuclear material (SNM) protection. Performance assurance includes several Hanford Site activities that conduct performance, acceptance, operability, effectiveness, and validation tests. These activities encompass areas of training, exercises, quality assurance, conduct of operations, total quality management, self assessment, classified matter protection and control, emergency preparedness, and corrective actions tracking and trending. The objective of the Performance Assurance Program is to capture the critical data of the tests, training, etc., in a cost-effective, manageable program that reflects the overall effectiveness of the program while minimizing operational impacts. To aid in achieving this objective, BWP will coordinate the Performance Assurance Program for Fluor Daniel Hanford, Inc. (FDH) and serve as the central point for data collection.

  19. Knowledge and motor performance.

    Science.gov (United States)

    Kerr, R; Boucher, J L

    1992-06-01

    Traditionally, motor skill acquisition has implied that the performance of a given individual on a particular skill is dependent on the amount of prior practice of that skill. However, concepts such as schema theory, or kinetic formulae, or the strategic allocation of resources imply that, even when practising specific skills, performers gain knowledge about their own motor performance which can be used or applied to related or novel situations. An attempt was made to relate the performance of a complex psychomotor task to differing levels of motor skill expertise or knowledge (athlete and nonathlete). 20 subjects performed (1600 responses) on a novel pursuit or tracking task. Analysis indicated that the athletes performed significantly better. Their main advantage appeared to be more in their ability to control and produce fast, accurate movements than in their decision-making. Accepting Henry and Rogers' 1960 proposition that there is no such thing as a general motor ability or coordination factor does not imply that the only alternative is for all motor skills to be specific. It is argued that the differences in the present study arose from the athletes' greater knowledge (schema, kinetic formulae) related to their understanding of their own motor capabilities.

  20. Hydration and physical performance.

    Science.gov (United States)

    Murray, Bob

    2007-10-01

    There is a rich scientific literature regarding hydration status and physical function that began in the late 1800s, although the relationship was likely apparent centuries before that. A decrease in body water from normal levels (often referred to as dehydration or hypohydration) provokes changes in cardiovascular, thermoregulatory, metabolic, and central nervous function that become increasingly greater as dehydration worsens. Similarly, performance impairment often reported with modest dehydration (e.g., -2% body mass) is also exacerbated by greater fluid loss. Dehydration during physical activity in the heat provokes greater performance decrements than similar activity in cooler conditions, a difference thought to be due, at least in part, to greater cardiovascular and thermoregulatory strain associated with heat exposure. There is little doubt that performance during prolonged, continuous exercise in the heat is impaired by levels of dehydration >or= -2% body mass, and there is some evidence that lower levels of dehydration can also impair performance even during relatively short-duration, intermittent exercise. Although additional research is needed to more fully understand low-level dehydration's effects on physical performance, one can generalize that when performance is at stake, it is better to be well-hydrated than dehydrated. This generalization holds true in the occupational, military, and sports settings.

  1. Phospholipids and sports performance

    Directory of Open Access Journals (Sweden)

    Purpura Martin

    2007-07-01

    Full Text Available Abstract Phospholipids are essential components of all biological membranes. Phosphatidylcholine (PC and Phosphatidylserine (PS are Phosphatidyl-phospholipids that are required for normal cellular structure and function. The participation in physical activity often challenges a variety of physiological systems; consequently, the ability to maintain normal cellular function during activity can determine sporting performance. The participation in prolonged intense exercise has been shown to reduce circulatory choline concentrations in some individuals. As choline is a pre-cursor to the neurotransmitter Acetylcholine, this finding has encouraged researchers to investigate the hypothesis that supplementation with PC (or choline salts could enhance sporting performance. Although the available data that evaluates the effects of PC supplementation on performance are equivocal, acute oral supplementation with PC (~0.2 g PC per kg body mass has been demonstrated to improve performance in a variety of sporting activities where exercise has depleted circulatory choline concentrations. Short term oral supplementation with soy-derived PS (S-PS has been reported to attenuate circulating cortisol concentrations, improve perceived well-being, and reduce perceived muscle soreness after exercise. More recently, short term oral supplementation (750 mg per day of S-PS for 10 days has been demonstrated to improve exercise capacity during high intensity cycling and tended to increase performance during intermittent running. Although more research is warranted to determine minimum dietary Phospholipid requirements for optimal sporting performance, these findings suggest that some participants might benefit from dietary interventions that increase the intakes of PC and PS.

    Repository performance confirmation links the technical bases of repository science and societal acceptance. This paper explores the myriad aspects of what has been labeled performance confirmation in U.S. programs, which involves monitoring as a collection of distinct activities combining technical and social significance in radioactive waste management. This paper is divided into four parts: (1) A distinction is drawn between performance confirmation monitoring and other testing and monitoring objectives; (2) A case study illustrates confirmation activities integrated within a long-term testing and monitoring strategy for Yucca Mountain; (3) A case study reviews compliance monitoring developed and implemented for the Waste Isolation Pilot Plant; and (4) An approach for developing, evaluating and implementing the next generation of performance confirmation monitoring is presented. International interest in repository monitoring is exhibited by the European Commission Seventh Framework Programme 'Monitoring Developments for Safe Repository Operation and Staged Closure' (MoDeRn) Project. The MoDeRn partners are considering the role of monitoring in a phased approach to the geological disposal of radioactive waste. As repository plans advance in different countries, the need to consider monitoring strategies within a controlled framework has become more apparent. The MoDeRn project pulls together technical and societal experts to assimilate a common understanding of a process that could be followed to develop a monitoring program. A fundamental consideration is the differentiation of confirmation monitoring from the many other testing and monitoring activities. Recently, the license application for Yucca Mountain provided a case study including a technical process for meeting regulatory requirements to confirm repository performance as well as considerations related to the preservation of retrievability.

    The energy performance of buildings are intimately connected to the energy performance of building envelopes. The better we understand the relation between the quality of the envelope and the energy consumption of the building, the better we can improve both. We have to consider not only heating but all service energies related to the human comfort in the building, such as cooling, ventilation, lighting as well. The complexity coming from this embracing approach is not to be underestimated. It is less and less possible to realted simple characteristic performance indicators of building envelopes (such as the U-value) to the overall energy performance. On the one hand much more paramters (e.g. light transmittance) come into the picture we have to assess the product quality in a multidimensional world. Secondly buildings more and more have to work on a narrow optimum: For an old, badly insulated building all solar gains are useful for a high-performance building with very good insulation and heat recovery systems in the ventilation overheating becomes more likely. Thus we have to control the solar gains, and sometimes we need high gains, sometimes low ones. And thirdly we see that the technology within the building and the user patterns and interactions as well influence the performance of a building envelope. The aim of this project within IEA Task27 was to improve our knowledge on the complex situation and also to give a principal approach how to assess the performance of the building envelope. The participants have contributed to this aim not pretending that we have reached the end. (au)

    The leading indicators of business performance cannot be found in financial data alone. Quality, customer satisfaction, innovation, market share--metrics like these often reflect a company's economic condition and growth prospects better than its reported earnings do. Depending on an accounting department to reveal a company's future will leave it hopelessly mired in the past. More and more managers are changing their company's performance measurement systems to track nonfinancial measures and reinforce new competitive strategies. Five activities are essential: developing an information architecture; putting the technology in place to support this architecture; aligning bonuses and other incentives with the new system; drawing on outside resources; and designing an internal process to ensure the other four activities occur. New technologies and more sophisticated databases have made the change to nonfinancial performance measurement systems possible and economically feasible. Industry and trade associations, consulting firms, and public accounting firms that already have well-developed methods for assessing market share and other performance metrics can add to the revolution's momentum--as well as profit from the business opportunities it presents. Every company will have its own key measures and distinctive process for implementing the change. But making it happen will always require careful preparation, perseverance, and the conviction of the CEO that it must be carried through. When one leading company can demonstrate the long-term advantage of its superior performance on quality or innovation or any other nonfinancial measure, it will change the rules for all its rivals forever.

  5. Ketones and Human Performance.

    Science.gov (United States)

    Scott, Jonathan M; Deuster, Patricia A

    Everyone is seeking nutritional strategies that might benefit performance. One approach receiving much attention is ketones, or ketosis. Ketones are very simple compounds made of hydrogen, carbon, and oxygen, and ketosis is a metabolic state whereby the body uses predominantly ketones. Ketosis can be achieved by fasting for longer than 72 hours or by following a very lowcarbohydrate, high-fat diet (ketogenic diet) for several days to weeks. Alternatively, ketone supplements purportedly induce ketosis rapidly and do not require strict adherence to any specific type of diet; however, much of the touted benefits are anecdotal. A potential role for ketosis as a performance enhancer was first introduced in 1983 with the idea that chronic ketosis without caloric restriction could preserve submaximal exercise capability by sparing glycogen or conserving the limited carbohydrate stores. Few human studies on the effects of a ketogenic diet on performance have yielded positive results, and most studies have yielded equivocal or null results, and a few negative results. Many questions about ketones relevant to Special Operations Forces (SOF) remain unanswered. At present, a ketogenic diet and/or a ketone supplement do not appear confer performance benefits for SOF. Instead, Operators should engage with their unit dietitian to develop individualized nutritional strategies based on unique mission requirements. The authors review the concept of a ketogenic diet, describe some potential benefits and risks of ketosis, review the performance literature and how to measure ketone status, and then summarize the landscape in 2017. 2017.

  6. Cognitive performance and dehydration.

    Adan, Ana

    No matter how mild, dehydration is not a desirable condition because there is an imbalance in the homeostatic function of the internal environment. This can adversely affect cognitive performance, not only in groups more vulnerable to dehydration, such as children and the elderly, but also in young adults. However, few studies have examined the impact of mild or moderate dehydration on cognitive performance. This paper reviews the principal findings from studies published to date examining cognitive skills. Being dehydrated by just 2% impairs performance in tasks that require attention, psychomotor, and immediate memory skills, as well as assessment of the subjective state. In contrast, the performance of long-term and working memory tasks and executive functions is more preserved, especially if the cause of dehydration is moderate physical exercise. The lack of consistency in the evidence published to date is largely due to the different methodology applied, and an attempt should be made to standardize methods for future studies. These differences relate to the assessment of cognitive performance, the method used to cause dehydration, and the characteristics of the participants.

    A system for labelling buildings in a manner similar to product labelling already well established with respect to goods and materials in general, was proposed. The system envisaged would differ from existing labelling systems in that it would follow the principles incorporated into `Green Building Challenge `98`, (GBC`98) The GBC`98 is a two-year process of international building performance assessment, whose goal is to inform the international community of scientists, designers and builders about advances in green building performance. GBC`98 also aims to test and demonstrate an improved method for measuring building performance, establish international benchmarks for building performance while respecting regional and technical diversity, showcase `best-practice` examples of green buildings around the world, document successful elements in individual green buildings and offer direction to participating countries in the development of regionally sensitive assessment models. The genesis of GBC`98, its potential applications as a second generation tool for eco-labeling of buildings was summarized, along with a review of existing building performance assessment systems. 4 refs.

    Implementation of a Total Quality Management (TQM) approach to engineering work required the development of a system of metrics which would serve as a meaningful management tool for evaluating effectiveness in accomplishing project objectives and in achieving improved customer satisfaction. A team effort was chartered with the goal of developing a system of engineering performance metrics which would measure customer satisfaction, quality, cost effectiveness, and timeliness. The approach to developing this system involved normal systems design phases including, conceptual design, detailed design, implementation, and integration. The lessons teamed from this effort will be explored in this paper. These lessons learned may provide a starting point for other large engineering organizations seeking to institute a performance measurement system accomplishing project objectives and in achieving improved customer satisfaction. To facilitate this effort, a team was chartered to assist in the development of the metrics system. This team, consisting of customers and Engineering staff members, was utilized to ensure that the needs and views of the customers were considered in the development of performance measurements. The development of a system of metrics is no different than the development of any type of system. It includes the steps of defining performance measurement requirements, measurement process conceptual design, performance measurement and reporting system detailed design, and system implementation and integration.

  13. Expert status and performance.

    Directory of Open Access Journals (Sweden)

    Mark A Burgman

    Full Text Available Expert judgements are essential when time and resources are stretched or we face novel dilemmas requiring fast solutions. Good advice can save lives and large sums of money. Typically, experts are defined by their qualifications, track record and experience. The social expectation hypothesis argues that more highly regarded and more experienced experts will give better advice. We asked experts to predict how they will perform, and how their peers will perform, on sets of questions. The results indicate that the way experts regard each other is consistent, but unfortunately, ranks are a poor guide to actual performance. Expert advice will be more accurate if technical decisions routinely use broadly-defined expert groups, structured question protocols and feedback.

Cryogenic layered target implosions and experiments with surrogate targets produce an abundance of capsule performance data including implosion velocity, remaining ablator mass, times of peak x-ray and neutron emission, core image size, core symmetry, neutron yield, and x-ray spectra. We have attempted to match the integrated data set with capsule-only simulations by adjusting the drive and other physics parameters within expected uncertainties. The simulations include interface roughness, time-dependent symmetry, and a model of mix. We were able to match many of the measured performance parameters for a selection of shots.

    Full Text Available Performance measurement systems are an extremely important part of the control and management actions, because in this way a company can determine its business potential, its market power, potential and current level of business efficiency. The significance of measurement consists in influencing the relationship between the results of reproduction (total volume of production, value of production, total revenue and profit and investments to achieve these results (factors of production spending and hiring capital in order to achieve the highest possible quality of the economy. (The relationship between the results of reproduction and investment to achieve them quantitatively determines economic success as the quality of the economy.

    Full Text Available Digital literature is a complex assemblage of related elements –material, spatial, linguistic, performative, textual, cultural, social– each of which is at one time interdependent and detached. This article discusses the literary creation within the cyberculture from the performativity point of view in relation to the textual apparatus. This is done through the analysis of a selection of performances where physical corporeality has a collaborative function with the body to a greater or lesser degree. Therefore, this physical feature can not only change, but stand at three possible and hybridizable axes: 1 the digital text as protagonist, 2 the digital text as counterpart, and 3 the digital text as site.

    In last 50 years, the field of scientific computing has seen a rapid change of vendors, architectures, technologies and the usage of systems. Despite all these changes the evolution of performance on a large scale however seems to be a very steady and continuous process. Moore's Law is often cited in this context. If the authors plot the peak performance of various computers of the last 5 decades in Figure 1 that could have been called the supercomputers of their time they indeed see how well this law holds for almost the complete lifespan of modern computing. On average they see an increase in performance of two magnitudes of order every decade.

    Full Text Available Mindfulness in sports is a recent field. While sport psychology relied mainly on “second wave” cognitive-behavioural interventions for the last four decades, a new approach has recently been developed in sport psychology including mindfulness: a “third wave” approach. This new approach assumes that ideal performance is a state that is not based on self-control or change in behaviour, but rather a state that arises from recognition and acceptance of thoughts, emotions and bodily sensations. Practicing mindfulness allows learns to observe and accept the thoughts, emotions, and body sensations, without making any attempt to eliminate or modify them. This paper reviews the main programs of mindfulness in sport performance both from the “third wave”: Mindful Sport Performance Enhancement (MSPE and Mindfulness-Acceptance-Commitment(MAC.

    João Antonio Telles

    Full Text Available Teletandem is a virtual autonomous VoIP2technology-based context (webcam images, voice and text. Within this context, two students help each other learn their native (or other language through intercultural and linguistic collaboration. Performative Theory can shed light on the constitution of these students' national identities, as they engage in linguistic performances of marking and discussing differences between their countries during teletandem. Based on critical approaches to discourse and intercultural communication, my analysis shows that this online intercultural contact opens innovative possibilities for foreign language teachers to promote intercultural contact with "the different". However, without teacher mediation, teletandem interactions may fall into shallow performances of sedimented and pre-given representations of self and other. Subsequently, this article concludes with a discussion of relevant pedagogical points for foreign language teachers.

    Iwamoto, Shoichi; Hirata, Koichi; Toda, Fujio

    We have developed five kinds of high- and low-temperature differential Stirling engines and their engine performance was investigated experimentally. In order to determine the parameters that affect engine performance, experimental results were discussed and compared with results calculated using analytical methods. We show an arranging method for the experimental results, and consider the performance of general Stirling engines. After using the arranging method with nondimensional numbers obtained by a dimensional analysis, a prediction method, which is used at the early design stage, is formulated. One of the nondimensional numbers in this prediction method is calculated based on engine specifications, including the properties of the working gas. The prediction method can predict engine speed, output power, the effect of working gas and operating conditions.

    A clinical link exists between severe dehydration and cognitive performance. Using rapid and severe water loss induced either by intense exercise and/or heat stress, initial studies suggested there were alterations in short-term memory and cognitive function related to vision, but more recent studies have not all confirmed these data. Some studies argue that water loss is not responsible for the observations made, and studies compensating water losses have failed to prevent the symptoms. Studies in children have suggested that drinking extra water helps cognitive performance, but these data rely on a small number of children. In older adults (mean age around 60) the data are not strong enough to support a relationship between mild dehydration and cognitive function. Data on frail elderly and demented people are lacking. Methodological heterogeneity in these studies are such that the relationship between mild dehydration and cognitive performance cannot be supported.

    2007-10-01

    Human neuropsychology investigates brain-behavior relationships, using objective tools (neurological tests) to tie the biological and behavior aspects together. The use of neuropsychological assessment tools in assessing potential effects of dehydration is a natural progression of the scientific pursuit to understand the physical and mental ramifications of dehydration. It has long been known that dehydration negatively affects physical performance. Examining the effects of hydration status on cognitive function is a relatively new area of research, resulting in part from our increased understanding of hydration's impact on physical performance and advances in the discipline of cognitive neuropsychology. The available research in this area, albeit sparse, indicates that decrements in physical, visuomotor, psychomotor, and cognitive performance can occur when 2% or more of body weight is lost due to water restriction, heat, and/or physical exertion. Additional research is needed, especially studies designed to reduce, if not remove, the limitations of studies conducted to date.

    2003-01-01

    Participants received 1 of 3 instructional sets designed to manipulate their performance standards (i.e., criteria used to evaluate hypnotic performance): (a) stringent set (n = 33), these subjects were told that responsive subjects respond immediately to hypnosis and imagine realistically, (b) lenient set (n = 30), these subjects were told that responsive subjects do not necessarily respond immediately or imagine realistically, and (c) control set (n = 34), standard prehypnotic information. As expected, compared to controls, stringent set participants were less responsive to hypnosis, as indexed by measures of actual and estimated suggestibility, subjective involvement, involuntariness, quickness of responding, satisfaction, and imaginative ability. Stringent set participants estimated they passed fewer suggestions, were less satisfied with their performance, and reported less subjective involvement than individuals in the lenient condition.

    The LHCb detector is a forward spectrometer at the Large Hadron Collider (LHC) at CERN. The experiment is designed for precision measurements of CP violation and rare decays of beauty and charm hadrons. In this paper the performance of the various LHCb sub-detectors and the trigger system are described, using data taken from 2010 to 2012. It is shown that the design criteria of the experiment have been met. The excellent performance of the detector has allowed the LHCb collaboration to publish a wide range of physics results, demonstrating LHCb's unique role, both as a heavy flavour experiment and as a general purpose detector in the forward region.

  12. Creating sustainable performance.

    Science.gov (United States)

    Spreitzer, Gretchen; Porath, Christine

    2012-01-01

    What makes for sustainable individual and organizational performance? Employees who are thriving-not just satisfied and productive but also engaged in creating the future. The authors found that people who fit this description demonstrated 16% better overall performance, 125% less burnout, 32% more commitment to the organization, and 46% more job satisfaction than their peers. Thriving has two components: vitality, or the sense of being alive and excited, and learning, or the growth that comes from gaining knowledge and skills. Some people naturally build vitality and learning into their jobs, but most employees are influenced by their environment. Four mechanisms, none of which requires heroic effort or major resources, create the conditions for thriving: providing decision-making discretion, sharing information about the organization and its strategy, minimizing incivility, and offering performance feedback. Organizations such as Alaska Airlines, Zingerman's, Quicken Loans, and Caiman Consulting have found that helping people grow and remain energized at work is valiant on its own merits-but it can also boost performance in a sustainable way.

  16. Insights Through Performative Approaches

    2008-05-01

    Full Text Available This script aims to explore how performative approaches can be used to enhance the understanding of social situations by going beyond the presenting or outermost layer of a problem. The script evolves in six acts and focuses on a group of academics and consultants who meet to develop a theoretical understanding of performative approaches, to experiment with performative approaches by applying them to a consulting case, and finally to reflect on the learning experiences and the understanding of social situations implicit in the case. We found that with traditional scientific methods it may be difficult to understand the underlying—often unconscious—dynamics, emotions and resistances within social situations. Using performative approaches opens up the possibility to gain an understanding of the social situation beyond the rational and cognitive level. In particular, the use of creative approaches like painting, role-plays or fairy tales may allow new and alternative perspectives and interpretations of a social situation to emerge. The script concludes with practical implications for action research in the context of organizational consulting and development. URN: urn:nbn:de:0114-fqs0802444

    1994-01-01

    The objective of this contract was the investigation of the potential performance gains that would result from an upgrade of the Space Station Freedom (SSF) Data Management System (DMS) Embedded Data Processor (EDP) '386' design with the Intel Pentium (registered trade-mark of Intel Corp.) '586' microprocessor. The Pentium ('586') is the latest member of the industry standard Intel X86 family of CISC (Complex Instruction Set Computer) microprocessors. This contract was scheduled to run in parallel with an internal IBM Federal Systems Company (FSC) Internal Research and Development (IR&D) task that had the goal to generate a baseline flight design for an upgraded EDP using the Pentium. This final report summarizes the activities performed in support of Contract NAS2-13758. Our plan was to baseline performance analyses and measurements on the latest state-of-the-art commercially available Pentium processor, representative of the proposed space station design, and then phase to an IBM capital funded breadboard version of the flight design (if available from IR&D and Space Station work) for additional evaluation of results. Unfortunately, the phase-over to the flight design breadboard did not take place, since the IBM Data Management System (DMS) for the Space Station Freedom was terminated by NASA before the referenced capital funded EDP breadboard could be completed. The baseline performance analyses and measurements, however, were successfully completed, as planned, on the commercial Pentium hardware. The results of those analyses, evaluations, and measurements are presented in this final report.

    During May and June 2003, the U.S. Geological Survey installed monitoring wells and collected data to characterize the effectiveness of natural attenuation processes for remediating petroleum-contaminated ground water at Operable Unit A of the former Naval complex on Adak Island, Alaska. In addition, the evidence for petroleum biodegradation in ground water was evaluated at selected petroleum sites, plans for future natural attenuation monitoring were suggested for the selected petroleum sites, and the natural attenuation monitoring strategy for the Downtown area of Adak Island was reviewed and refinements were suggested. U.S. Geological Survey personnel measured water levels and collected ground-water samples from about 100 temporary boreholes and 50 monitoring wells. Most samples were analyzed on-site for concentrations of selected petroleum compounds and natural attenuation parameters such as dissolved oxygen, ferrous iron, and carbon dioxide. The U.S. Geological Survey evaluated the data on-site, selected new monitoring well locations, and installed, developed, and sampled 10 monitoring wells. The review and suggestions for the natural attenuation monitoring strategy focused on how to better achieve monitoring objectives specified in the Record of Decision for Adak Island petroleum sites. To achieve the monitoring objective of verifying that natural attenuation is occurring, the monitoring plans for each monitored natural attenuation site need to include sampling of at least one strategically placed well at the downgradient margin of the contaminant plume margin, preferably where contaminant concentrations are detectable but less than the cleanup level. Collection of natural attenuation parameter data and sampling background wells is no longer needed to achieve the monitoring objective of demonstrating the occurrence of natural attenuation. To achieve the objective of monitoring locations where chemical concentrations exceed specified cleanup levels, at least

    Human factors is a critical discipline for human spaceflight. Nearly every human factors research area is relevant to space exploration -- from the ergonomics of hand tools used by astronauts, to the displays and controls of a spacecraft cockpit or mission control workstation, to levels of automation designed into rovers on Mars, to organizational issues of communication between crew and ground. This chapter focuses more on the ways in which the space environment (especially altered gravity and the isolated and confined nature of long-duration spaceflight) affects crew performance, and thus has specific novel implications for human factors research and practice. We focus on four aspects of human performance: neurovestibular integration, motor control and musculo-skeletal effects, cognitive effects, and behavioral health. We also provide a sampler of recent human factors studies from NASA.

The analysis shows information in the MIR may be used to improve tape subsystem operations. Most notably, we found the MIR information to be helpful in determining whether the drive or tape was most suspect given a read or write error, and for helping identify which tapes should not be reused given their history of read or write errors. We also explored using the MIR Assisted Search to order file retrieval requests. We found that MIR Assisted Search may be used to reduce the time needed to retrieve collections of files from a tape volume.

  17. Neurology of musical performance.

    Science.gov (United States)

    Altenmüller, Eckart

    2008-08-01

    Performing music at a professional level requires the integration of multimodal sensory and motor information and precise monitoring of the performance via auditory feedback. In the context of Western classical music, musicians are forced to reproduce highly controlled movements almost perfectly with a high reliability. These specialised sensorimotor skills are acquired during extensive training periods over many years. The superior skills of musicians are mirrored in functional and structural plastic adaptations of sensorimotor and auditory systems of the brain. Auditory-sensorimotor integration, for example, is accompanied by rapid modulations of neuronal connectivity in the time range of 20 minutes. Finally, dysfunctional plasticity in musicians, known as musician's dystonia, leads to deterioration of extensively trained fine motor skills. Musician's dystonia may be caused by training induced dysplasticity with pathological fusion of central nervous representations in sensorimotor cortical and subcortical brain regions.

    van Dam, M A

    2004-05-26

    Characterizing an adaptive optics (AO) system refers to understanding its performance and limitations. The goal of an AO system is to correct wavefront aberrations. The uncorrected aberrations, called the residual errors and referred to in what follows simply as the errors, degrade the image quality in the science camera. Understanding the source of these errors is a great aid in designing an AO system and optimizing its performance. This chapter explains how to estimate the wavefront error terms and the relationship between the wavefront error and the degradation of the image. The analysis deals with the particular case of a HartmannShack wavefront sensor (WFS) and a continuous deformable mirror (DM), although the principles involved can be applied to any AO system.

    Materials and structures used for flat plate solar collectors and evacuated tubular collectors were examined relative to their overall performance to project effectiveness for building heating and cooling and the feasibility of use for generating industrial process heat. Thermal efficiencies were calculated for black paint single glazed, selective surface single glazed, and selective surface double glazed flat plate collectors. The efficiencies of a single tube and central tube accompanied by two side tube collectors were also studied. Techniques for extending the lifetimes of the collectors were defined. The selective surface collectors proved to have a performance superior to other collectors in terms of the average annual energy delivered. Addition of a black chrome-coated fin system to the evacuated collectors produced significant collection efficiency increases.

  15. ATR performance modeling concepts

    Ross, Timothy D.; Baker, Hyatt B.; Nolan, Adam R.; McGinnis, Ryan E.; Paulson, Christopher R.

    2016-05-01

    Performance models are needed for automatic target recognition (ATR) development and use. ATRs consume sensor data and produce decisions about the scene observed. ATR performance models (APMs) on the other hand consume operating conditions (OCs) and produce probabilities about what the ATR will produce. APMs are needed for many modeling roles of many kinds of ATRs (each with different sensing modality and exploitation functionality combinations); moreover, there are different approaches to constructing the APMs. Therefore, although many APMs have been developed, there is rarely one that fits a particular need. Clarified APM concepts may allow us to recognize new uses of existing APMs and identify new APM technologies and components that better support coverage of the needed APMs. The concepts begin with thinking of ATRs as mapping OCs of the real scene (including the sensor data) to reports. An APM is then a mapping from explicit quantized OCs (represented with less resolution than the real OCs) and latent OC distributions to report distributions. The roles of APMs can be distinguished by the explicit OCs they consume. APMs used in simulations consume the true state that the ATR is attempting to report. APMs used online with the exploitation consume the sensor signal and derivatives, such as match scores. APMs used in sensor management consume neither of those, but estimate performance from other OCs. This paper will summarize the major building blocks for APMs, including knowledge sources, OC models, look-up tables, analytical and learned mappings, and tools for signal synthesis and exploitation.

In Experiment 1, college students (n = 20 carried out 2- and 3-digit addition and multiplication problems under time pressure. In Experiment 2, experienced golfers (n = 12, also college students, putted toward a target from nine different locations. Within each experiment, we analyzed the same responses using different methods. For the arithmetic tasks, accuracy information (mean absolute deviation from the correct answer, MAD using a coherence criterion was available; for golf, accuracy information using a correspondence criterion (mean deviation from the target, also MAD was available. We ranked the performances of the participants according to each measure, then compared the orders using Spearman's rextsubscript{s}. For mental calculation, the CWS order correlated moderately (rextsubscript{s} =.46 with that of MAD. However, a different coherence criterion, degree of model fit, did not correlate with either CWS or accuracy. For putting, the ranking generated by CWS correlated .68 with that generated by MAD. Consensual answers were also available for both experiments, and the rankings they generated correlated highly with those of MAD. The coherence vs. correspondence distinction did not map well onto criteria for performance evaluation.

    Although the positive effects of implementing a human performance approach to operations can be hard to quantify, many organizations and industry areas are finding tangible benefits to such a program. Recently, a unique mentoring program was established and implemented focusing on improving the performance of managers, supervisors, and work crews, using the principles of Human Performance Improvement (HPI). The goal of this mentoring was to affect behaviors and habits that reliably implement the principles of HPI to ensure continuous improvement in implementation of an Integrated Safety Management System (ISMS) within a Conduct of Operations framework. Mentors engaged with personnel in a one-on-one, or one-on-many dialogue, which focused on what behaviors were observed, what factors underlie the behaviors, and what changes in behavior could prevent errors or events, and improve performance. A senior management sponsor was essential to gain broad management support. A clear charter and management plan describing the goals, objectives, methodology, and expected outcomes was established. Mentors were carefully selected with senior management endorsement. Mentors were assigned to projects and work teams based on the following three criteria: 1) knowledge of the work scope; 2) experience in similar project areas; and 3) perceived level of trust they would have with project management, supervision, and work teams. This program was restructured significantly when the American Reinvestment and Recovery Act (ARRA) and the associated funding came to an end. The program was restructured based on an understanding of the observations, attributed successes and identified shortfalls, and the consolidation of those lessons. Mentoring the application of proven methods for improving human performance was shown effective at increasing success in day-to-day activities and increasing confidence and level of skill of supervisors. While mentoring program effectiveness is difficult to

    We conducted an internet survey targeting healthcare providers in intensive care units (ICUs) in Japan and received 318 responses. Eighteen percent of respondents replied that full-time physical therapists (PTs) exist in their ICUs. Practicing sitting upright or sitting in a chair is frequently performed, while standing and walking are occasionally performed for patients undergoing mechanical ventilation. However, only 16 % of respondents use staged rehabilitation protocols. This preliminary survey suggests that full-time involvement of PTs in the ICU and introduction of rehabilitation protocols may not be common in Japanese ICUs.

    Talcott, Stephen

    High performance liquid chromatography (HPLC) has many applications in food chemistry. Food components that have been analyzed with HPLC include organic acids, vitamins, amino acids, sugars, nitrosamines, certain pesticides, metabolites, fatty acids, aflatoxins, pigments, and certain food additives. Unlike gas chromatography, it is not necessary for the compound being analyzed to be volatile. It is necessary, however, for the compounds to have some solubility in the mobile phase. It is important that the solubilized samples for injection be free from all particulate matter, so centrifugation and filtration are common procedures. Also, solid-phase extraction is used commonly in sample preparation to remove interfering compounds from the sample matrix prior to HPLC analysis.

    Most of the important physics processes to be studied in the international linear collider (ILC) experiment have multi-jets in the final state. In order to achieve better jet energy resolution, the so-called particle flow algorithm (PFA) will be employed and there is a general consensus that PFA derives overall ILC detector design. Four detector concepts for the ILC experiment have been proposed so far in the world; the GLD detector that has a large inner calorimeter radius, which is considered to have an advantage for a PFA, is one of them. In this paper, general scheme and performance of the GLD-PFA will be presented.

In spite of this, there does not yet exist a monograph that analyzes, describes, and explains sporting performance from the point of view of aleatorism as part of the theory of sport and physical culture. Unfortunately, no monograph has developed this issue in a multi-aspectual, holistic, culturological, and philosophical way, dealing with its axiological values (aesthetic and praxeological. This applies to the relations between this phenomenon and the mechanisms that bring about the development and growth of interest in the social dimension.

    Photothermal field performance in flat plate solar collectors was predicted. An analytical model which incorporates the measured dependency between transmittance loss and UV and temperature exposure levels was developed. The model uses SOLMET weather data extrapolated to 30 years for various sites and module mounting configurations. It is concluded that the temperature is the key to photothermally induced transmittance loss. The sensitivity of transmittance loss to UV level is nonlinear with minimum in curve near one sun. The ethylene vinyl acetate (EVA) results are consistent with 30 year life allocation.

    Full Text Available The term performativity and its inflexions have been applied to several concepts in the field of educational research. In this study, we trace the dissemination of the word performativity and its correlates, starting from the meanings attributed to the term by Stephen Ball, in his analysis of contemporary educational policies, but also using the theories of Jacques Derrida and Judith Butler, who used these terms to refer to social processes of signification and identification, and also references made to the term in studies of Anthropology, Arts, Political Science, Linguistics, Philosophy and Physics. On top of that, we researched studies in the field of academic education, examining articles from journals and other periodicals published over the last five years, in order to discuss the various meanings attributed to the term within the educational field. We present, in this paper, a synthesis of our investigations, highlighting the affirmations, negations and truth effects that can be construed from the use of these terms in educational research, in particular when approaching current educational policies.

    Full Text Available Was Plato the first philosophical dramatist to explore philosophical ideas through dramatic content, introducing dramatic structures currently in line with contemporary theatre? If Plato was an influential figure for philosophers as well as theatre-makers, it can arguably be said that he was a silent pioneer in creating the newly defined discipline of Performance Philosophy. There is an obvious polarity between performance and philosophy since both disciplines are on the quest of exploring and presenting what life is. At least this can be said of ancient Greek and Roman philosophy. Conceived as “biou techne” the art of living, Greek and Roman philosophers, especially the Epicureans, Stoics and Skeptics, saw philosophy as a way of conceiving what a good life is (a life worth living and pursuing its practical realization for the attainment of eudemonia. Plato was arguably the first significant philosopher to explore philosophical ideas through dramatic content, introducing dramatic structures currently in line with contemporary theatre views. As such, he can be seen as an influential figure for theatre makers as well as for philosophers. Plato’s artistic intention was to uncover the artist that lacked substance and support the knowledgeable creative philosophical mind that besides instant emotional pleasure has to contribute in social development.

    The goal for this project is to thoroughly characterize the thermal performance of state-of-the-art (SOA) in-production automotive power electronics and electric motor thermal management systems. Information obtained from these studies will be used to: evaluate advantages and disadvantages of different thermal management strategies; establish baseline metrics for the thermal management systems; identify methods of improvement to advance the SOA; increase the publicly available information related to automotive traction-drive thermal management systems; help guide future electric drive technologies (EDT) research and development (R&D) efforts. The thermal performance results combined with component efficiency and heat generation information obtained by Oak Ridge National Laboratory (ORNL) may then be used to determine the operating temperatures for the EDT components under drive-cycle conditions. In FY16, the 2012 Nissan LEAF power electronics and 2014 Honda Accord Hybrid power electronics thermal management system were characterized. Comparison of the two power electronics thermal management systems was also conducted to provide insight into the various cooling strategies to understand the current SOA in thermal management for automotive power electronics and electric motors.

  20. Exercise performance of reptiles.

    Bennett, A F

    1994-01-01

    From the vantage point of thirty years of study, we can sketch the general features of activity capacity and performance ability in reptiles. Extant reptilian groups all share low levels of maintenance metabolism and ectothermy, with their consequent advantages (Pough, 1980) and disadvantages. Among the latter is a limited capacity to expand aerobic metabolism, limited in comparison to the relatively great costs of terrestrial locomotion. Particularly at low body temperatures, reptiles outstrip their aerobic capacities with any exercise more intense than a slow walk. Anaerobic metabolism, particularly anaerobic glycolysis, can be used to fuel bursts of intense activity. As a consequence, however, physiological disruption and exhaustion are entailed. Under field conditions, many reptiles alternate long periods of quiescence or slow movement with very brief bursts of exertion. Other ectotherms with a similar pattern of metabolism have been shown thereby to extend performance beyond that supportable by either aerobic or anaerobic metabolism alone (Weinstein and Full, 1992). Even with careful alternation between these metabolic modes, reptiles remain particularly prone to exhaustion during vigorous activity, as least as judged by our mammalian frame of reference. Their capacities for burst activity and exertion have been shown, at least in some species, to be important determinants of their natural survival.

  1. Nutrition and sports performance.

    Brotherhood, J R

    1984-01-01

    During the past 20 years there have been great developments in the scientific understanding of the role of nutrition in health and physical performance. Epidemiological and physiological studies have provided evidence that certain forms of dietary behaviour may be linked with an increased risk of developing disorders such as high blood pressure, coronary artery disease and some cancers. This has resulted in dietary recommendations that are intended to reduce the incidence of these disorders in the community. The science of nutrition in relation to sports performance has progressed from empirical studies investigating the effects of dietary manipulations, such as restriction and supplementation, to the direct investigation of the physiological basis of the specific nutritional demands of hard physical exercise. This review is based on the premise that it is "what comes out' rather than "what goes in', which provides the clues to ideal nutrition for athletic performance. Various aspects of the physical demands of athletic exercise are viewed as stresses that induce specific biochemical, and hence nutritional, strains in the athlete. Training is the predominant demand in the athletic lifestyle. This is characterised by acute bouts of high power output. During one hour of hard training an athlete may expend 30% of his or her total 24-hour energy output. These high power outputs have important implications for energy substrate and water requirements. Carbohydrate, specifically muscle glycogen, is an obligatory fuel for the high power outputs demanded by athletic sports. Muscle glycogen is a limiting factor in hard exercise because it is held in limited amounts, utilised rapidly by intense exercise, and fatigue occurs when it is depleted to low levels in the active muscles. Liver glycogen may also be exhausted by hard exercise and low blood glucose contributes to fatigue. High sweat rates are demanded during severe exercise and large water deficits commensurate with

  2. On Performance Skill Representation Framework

    Science.gov (United States)

    Furukawa, Koichi; Shimizu, Satoshi; Yoshinaga, Saori

    In this paper, we propose a framework for representing performance skill. Firstly, we notice the importance of performance skill representation. We introduce five different representation targets: performance tasks, performance rules, pre-shaping actions, dynamic integrity constraints, and performance states. Performance task description consists of a sequence of performance tasks and expressions. It acts as a goal description in planning. Performance rules describe model performance methods for given tasks including how to shape body parts and how to use various muscles. Pre-shaping action rules are similar to performance rules. Its role is to pre-shape in between consecutive tasks to prepare for the next task. Dynamic integrity constraints specify constraints to be satisfied during performance. They provide such general rules as prohibiting simultaneous strong activations of agonist and antagonist. Performance states are for describing real performance done by players including professionals and amateurs. The aim of the framework is to provide a uniform scheme for representing model performance methods given performance score such as music score. The representation framework will define targets of inducing formal skill rules as well as describing performance states automatically from biomechanical performance data. It also is related to a fundamental research issue of attributes finding/selection in discovering useful rules for skillful performance. We conclude our paper by stating future research direction.

    The thermal performance of a PCM thermal storage unit (TSU) is studied numerically and experimentally. The TSU under analysis consists of several flat slabs of phase change material (PCM) with melting temperature of -26.7 C. Liquid heat transfer fluid (HTF) passes between the slabs to charge and discharge the storage unit. A one dimensional mathematical model was employed to analyze the transient thermal behavior of the storage unit during the melting and freezing processes. The model takes into consideration the temperature variations in the wall along the flow direction of the HTF. The paper compares the experimental and numerical simulation results in terms of HTF outlet temperatures during the melting period. (orig.)

    A new detector to measure the machine induced background at large radii (1.8 m from beam axis) has been developed and installed in the CMS experiment at LHC. It consists of 40 modules, each comprising a quartz bar read out by a photomultiplier. Since Cherenkov radiation is emitted in a forward cone around the charged particle trajectory, these detectors can distinguish the directions of the machine induced background. The back-end consists of a microTCA readout with excellent time resolution. The performance of the detector modules measured in several test-beam campaigns will be reported. The installation in CMS is described, and first results about operating the detector during data taking is given.

    Purpose – The paper analyses how public buyers transition from procuring single products and services to procuring complex performance (PCP). The aim is to examine the change in the interactions between buyer and supplier, the emergence of value co-creation and the capability development during...... the transition process. Design/methodology/approach – A multiple, longitudinal case study method is used to examine the transition towards PCP. The study deploys rich qualitative data sets by combining semi-structured interviews, focus group meetings and organisational reports and documents. Findings...... – The transition towards PCP can be best described as a learning process which cumulates the knowledge and experience in the client-supplier interaction accompanied by changing contractual and relational capabilities. In public infrastructure this process is not initially motivated by the benefits of value co...

    The testing of a prototype of an automotive Stirling engine, the Mod II, is discussed. The Mod II is a one-piece cast block with a V-4 single-crankshaft configuration and an annular regenerator/cooler design. The initial testing of Mod II concentrated on the basic engine, with auxiliaries driven by power sources external to the engine. The performance of the engine was tested at 720 C set temperature and 820 C tube temperature. At 720 C, it is observed that the power deficiency is speed dependent and linear, with a weak pressure dependency, and at 820 C, the power deficiency is speed and pressure dependent. The effects of buoyancy and nozzle spray pattern on the heater temperature spread are investigated. The characterization of the oil pump and the operating cycle and temperature spread tests are proposed for further evaluation of the engine.

    1982-05-01

    The safety characteristics of the high-temperature gas-cooled reactor (HTGR) during normal and accident conditions are determined in part by HTGR fuel performance. During normal operation, less than 0.1% fuel failure occurs, primarily from defective particles. This low fuel failure fraction limits circulating activity to acceptable levels. During severe accidents, the radiological consequence is influenced by high-temperature fuel particle behavior. An empirical fuel failure model, supported by recent experimental data, is presented. The onset of significant fuel particle failure occurs at temperatures in excess of 1600/sup 0/C, and complete fuel failure occurs at 2660/sup 0/C. This indicates that the fuel is more retentive at higher temperatures than previously assumed. The more retentive nature of the fuel coupled with the high thermal capacitance of the core results in slow release of fission products from the core during severe accidents.

This concept it is understood as a micro-society with its own characteristics derived from the dynamic of socialization and training process. This research aims to investigate certain specific aspects of micro-sociology and emphasis on classroom culture. A relatively new concept is reflected by the normative consensus or the integrated system of values that belongs to the teachers, pupils and school, as a social entity. The integrative ensemble of values, class cohesion degree and training strategies are only a few of the aspects described by 62 pupils aged 17-18 years old, from a very prestigious school in Bucharest. The perception of pupils regarding our concept is the effect of the relational practices and training used constantly by the teachers. Those practices reflect the school’s focus mostly on cognitive performance.

    Full Text Available This paper studies the performance of concrete whose chief components are natural aggregate and an organic binder —a thermosetting polyester resin— denominated polymer concrete or PC. The material was examined macro- and microscopically and its basic physical and mechanical properties were determined using mercury porosimetry, scanning electron microscopy (SEM-EDAX, X-ray diffraction (XRD and strength tests (modulus of elasticity, stress-strain curves and ultimate strengths. According to the results of these experimental studies, the PC exhibited a low density (4.8%, closed pore system and a concomitantly continuous internal microstructure. This would at least partially explain its mechanical out-performance of traditional concrete, with average compressive and flexural strength values of 100 MPa and over 20 MPa, respectively. In the absence of standard criteria, the bending test was found to be a useful supplement to compressive strength tests for establishing PC strength classes.Este trabajo de investigación aborda el estudio de un hormigón de altas prestaciones, formado por áridos naturales y un aglomerante orgánico constituido por una resina termoestable poliéster, denominado hormigón polimérico HP.

    MPQC (Massively Parallel Quantum Chemistry) is a widely used computational quantum chemistry code. It is capable of performing a number of computations commonly occurring in quantum chemistry. In order to achieve better performance of MPQC, in this report we present a detailed performance analysis of this code. We then perform loop and memory access optimizations, and measure performance improvements by comparing the performance of the optimized code with that of the original MPQC code. We observe that the optimized MPQC code achieves a significant improvement in the performance through a better utilization of vector processing and memory hierarchies.

    The development of permanent lunar bases is constrained by performance of construction materials and availability of in-situ resources. Concrete seems a suitable construction material for the lunar environment, but water, one of its major components, is an extremely scarce resource on the Moon. This study explores an alternative to hydraulic concrete by replacing the binding mix of concrete (cement and water) with sulfur. Sulfur is a volatile element on the lunar surface that can be extracted from lunar soils by heating. Sulfur concrete mixes were prepared to investigate the effect of extreme environmental conditions on the properties of sulfur concrete. A hypervelocity impact test was conducted, having as its target a 5-cm cubic sample of sulfur concrete. This item consisted of JSC-1 lunar regolith simulant (65%) and sulfur (35%). The sample was placed in the MSFC Impact Test Facility s Micro Light Gas Gun target chamber, and was struck by a 1-mm diameter (1.4e-03 g) aluminum projectile at 5.85 km/s. In addition, HZTERN code, provided by NASA was used to study the effectiveness of sulfur concrete when subjected to space radiation.

    The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument onboard the National Aeronautics and Space Administration's Terra spacecraft has an along-track stereoscopic capability using its a near-infrared spectral band to acquire the stereo data. ASTER has two telescopes, one for nadir-viewing and another for backward-viewing, with a base-to-height ratio of 0.6. The spatial resolution is 15 m in the horizontal plane. Parameters such as the line-of-sight vectors and the pointing axis were adjusted during the initial operation period to generate Level-1 data products with a high-quality stereo system performance. The evaluation of the digital elevation model (DEM) data was carried out both by Japanese and U.S. science teams separately using different DEM generation software and reference databases. The vertical accuracy of the DEM data generated from the Level-1A data is 20 m with 95% confidence without ground control point (GCP) correction for individual scenes. Geolocation accuracy that is important for the DEM datasets is better than 50 m. This appears to be limited by the spacecraft position accuracy. In addition, a slight increase in accuracy is observed by using GCPs to generate the stereo data. ?? 2005 IEEE.

    The second OECD Review of Spain's environmental performance reviews Spain's progress in the context of OECD environmental strategy for the first decade of the 21st century in relation to its own policy objectives. It praises a number of achievements such as in commitments to climate change policies and developments of cogeneration and renewable energy sources. Although emissions of sulphur dioxide from the energy sector have fallen since 1990 they are still high when measured per capita and per unit of GDP. The OECD recommends further control of emissions of SOx, NOx, VOCs and NH{sub 3}. Subsidies such as compulsory purchase of domestic coal by electricity producers are set to increase. The report recommends the phasing out of environmental subsidies (which has begun) and making use of economic instruments to encourage efficient resource management and reduction of pollutants. Greenhouse gas emissions increased by 38% between 1990 and 2002 and the outlook for the next few years is pessimistic. 39 figs., 31 tabs.

    The major goals of this project is to develop a suite of diagnostics to probe magnetic fields generated by the dynamics of high velocity interpenetrating plasma flows relevant to astrophysical collisionless shocks. Collisionless shocks are common in the universe and are responsible for decelerating and thermalizing supersonic plasma flows and accelerating a fraction of the incident particles to high energies. When high velocity, low density, plasma flows interact in astrophysics, turbulent electrostatic and electromagnetic waves are generated due to plasma instabilities, such as the Weibel instability. This can lead to localized pockets of very strong magnetic field generation. The net result is that the plasmas stagnate in what is called a collisionless shock. Understanding these enigmatic interactions requires well-controlled laboratory experiments able to validate the theory and the simulations. Time and spatially resolved magnetic field diagnostics are key to probing these frontier plasma dynamics, relevant to both astrophysics and laboratory applications of plasma physics. This project will enable us to develop the necessary diagnostics for this experiment on NIF. Our team has vast experience in performing laser experiments, theory, simulations and diagnostic development and is ideally suited for carrying out this work.

    A suite of Sensor Data Records (SDRs) and Environment Data Records (EDRs) is generated from the Joint Polar Satellite System (JPSS) operational environmental satellite system. The products include atmospheric, ocean, land surface and cryospheric products from the Visible Infrared Imaging Radiometer Suite (VIIRS); atmospheric sounding products from the Cross-track Infrared Sounder (CrIS) and the Advance Technology Microwave Sounder (ATMS); and ozone products from the Ozone Mapping and Profiler Suite (OMPS). These EDRs undergo a rigorous validation process and algorithm updates to achieve a product maturity needed for end user applications. Since the successful launch of Suomi National Polar Partnership (SNPP) satellite in October 2011, significant progresses have been made on calibration and validation of the SNPP data products. By far all products were publicly available and most products were ready for operational evaluation. Most products also are expected to meet requirements and work is underway to reach validated maturity status and fully operational use. Further developments and improvements of the algorithms for J1 have been planned based on the JPSS requirements and lessons learned from SNPP. Sensitivity and impact studies are performed as sensor test data become available. For the majority of data products, no significant changes in sensor input and corresponding sensor degradation are expected. However, the J1 products will undergo the same rigorous calibration and validation process as the S-NPP products once the on-orbit data are available. The schedule for the maturity of the J1 data products however is expected to be accelerated compared to that for S-NPP as lessons learned from the S-NPP mission will be applied to the J1 satellite data. In the presentation, we will provide an overview of the latest SNPP data products' quality status and the plan forward for JPSS-1 algorithm updates.

    Full Text Available Abstract Background Non alcoholic fatty liver disease (NAFL consists in the accumulation of fat vacuoles in the cytoplasm of hepatocytes. Many etiologic factors are associated with NAFL, such as, the metabolic syndrome factors, medications, bariatric surgery, nutritional disorders. However, very little information is available on the clinical relevance of this disorder as a health problem in the general population. Methods and design The aim of the study is establish the risk factors most frequently associated with NAFL in a general adult population assigned to the primary care units and to investigate the relationship between each component of the metabolic syndrome and the risk of having a NAFL. A population based case-control, observational and multicenter study will be carried out in 18 primary care units from the "Area de Gestión del Barcelonés Nord y Maresme" (Barcelona attending a population of 360,000 inhabitants and will include 326 cases and 370 controls. Cases are defined as all subjects fulfilling the inclusion criteria and with evidence of fatty liver in an abdominal ultrasonography performed for any reason. One control will be randomly selected for each case from the population, matched for age, gender and primary care center. Controls with fatty liver or other liver diseases will be excluded. All cases and controls will be asked about previous hepatic diseases, consumption of alcohol, smoking and drugs, and a physical examination, biochemical analyses including liver function tests, the different components of the metabolic syndrome and the HAIR score will also be performed. Paired controls will also undergo an abdominal ultrasonography. Discussion This study will attempt to determine the factors most frequently associated with the presence of NAFL investigate the relationship between the metabolic syndrome and the risk of fatty liver and study the influence of the different primary care professionals in avoiding the evolution

  17. Cognitive performance modeling based on general systems performance theory.

    Kondraske, George V

    2010-01-01

    General Systems Performance Theory (GSPT) was initially motivated by problems associated with quantifying different aspects of human performance. It has proved to be invaluable for measurement development and understanding quantitative relationships between human subsystem capacities and performance in complex tasks. It is now desired to bring focus to the application of GSPT to modeling of cognitive system performance. Previous studies involving two complex tasks (i.e., driving and performing laparoscopic surgery) and incorporating measures that are clearly related to cognitive performance (information processing speed and short-term memory capacity) were revisited. A GSPT-derived method of task analysis and performance prediction termed Nonlinear Causal Resource Analysis (NCRA) was employed to determine the demand on basic cognitive performance resources required to support different levels of complex task performance. This approach is presented as a means to determine a cognitive workload profile and the subsequent computation of a single number measure of cognitive workload (CW). Computation of CW may be a viable alternative to measuring it. Various possible "more basic" performance resources that contribute to cognitive system performance are discussed. It is concluded from this preliminary exploration that a GSPT-based approach can contribute to defining cognitive performance models that are useful for both individual subjects and specific groups (e.g., military pilots).

    Biological treatment of synthetic wastewater containing Cu(II) ions was realized in an activated sludge unit with pre-adsorption of Cu(II) onto powdered waste sludge (PWS). Box-Behnken experimental design method was used to investigate Cu(II), chemical oxygen demand (COD) and toxicity removal performance of the activated sludge unit under different operating conditions. The independent variables were the solids retention time (SRT, 5-30 d), hydraulic residence time (HRT, 5-25 h), feed Cu(II) concentration (0-50 mg L(-1)) and PWS loading rate (0-4 g h(-1)) while percent Cu(II), COD, toxicity (TOX) removals and the sludge volume index (SVI) were the objective functions. The data were correlated with a quadratic response function (R2=0.99). Cu(II), COD and toxicity removals increased with increasing PWS loading rate and SRT while decreasing with the increasing feed Cu(II) concentration and HRT. Optimum conditions resulting in maximum Cu(II), COD, toxicity removals and SVI values were found to be SRT of 30 d, HRT 15 h, PWS loading rate 3 g h(-1) and feed Cu(II) concentration of less than 30 mg L(-1).

    Advanced access is an organizational model that has shown promise in improving timely access to primary care. In Quebec, it has recently been introduced in several family medicine units (FMUs) with a teaching mission. The objectives of this paper are to analyze the principles of advanced access implemented in FMUs and to identify which factors influenced their implementation. A multiple case study of four purposefully selected FMUs was conducted. Data included document analysis and 40 semistructured interviews with health professionals and staff. Cross-case comparison and thematic analysis were performed. Three out of four FMUs implemented the key principles of advanced access at various levels. One scheduling pattern was observed: 90% of open appointment slots over three- to four-week periods and 10% of prebooked appointments. Structural and organizational factors facilitated the implementation: training of staff to support change, collective leadership, and openness to change. Conversely, family physicians practicing in multiple clinical settings, lack of team resources, turnover of clerical staff, rotation of medical residents, and management capacity were reported as major barriers to implementing the model. Our results call for multilevel implementation strategies to improve the design of the advanced access model in academic teaching settings.

    results of this project also filled a data gap for plants firing PRB coal and configured with an SCR, SDA, and FF, as many new plants are being designed today. Another goal of the project was to evaluate, on a short-term basis, the mercury removal associated with coal additives and coal blending with western bituminous coal. The additive test showed that, at this site, the coal additive known as KNX was affective at increasing mercury removal while decreasing sorbent usage. Coal blending was conducted with two different western bituminous coals, and West Elk coal increased native capture from nominally 10% to 50%. Two additional co-benefits were discovered at this site. First, it was found that native capture increased from nominally 10% at full load to 50% at low load. The effect is believed to be due to an increase in mercury oxidation across the SCR caused by a corresponding decrease in ammonia injection when the plant reduces load. Less ammonia means more active oxidation sites in the SCR for the mercury. The second co-benefit was the finding that high ammonia concentrations can have a negative impact on mercury removal by powdered activated carbon. For a period of time, the plant operated with a high excess of ammonia injection necessitated by the plugging of one-third of the SCR. Under these conditions and at high load, the mercury control system could not maintain 90% removal even at the maximum feed rate of 3.5 lb/MMacf (pounds of mercury per million actual cubic feet). The plant was able to demonstrate that mercury removal was directly related to the ammonia injection rate in a series of tests where the ammonia rate was decreased, causing a corresponding increase in mercury removal. Also, after the SCR was refurbished and ammonia injection levels returned to normal, the mercury removal performance also returned to normal. Another goal of the project was to install a commercial-grade activated carbon injection (ACI) system and integrate it with new

    Full Text Available Abstract Background Limited data are available concerning patients admitted to the intensive care unit (ICU for severe haemoptysis. We reviewed a large series of patients managed in a uniform way to describe the clinical spectrum and outcome of haemoptysis in this setting, and better define the indications for bronchial artery embolisation (BAE. Methods A retrospective chart review of 196 patients referred for severe haemoptysis to a respiratory intermediate care ward and ICU between January 1999 and December 2001. A follow-up by telephone interview or a visit. Results Patients (148 males were aged 51 (± sd, 16 years, with a median cumulated amount of bleeding averaging 200 ml on admission. Bronchiectasis, lung cancer, tuberculosis and mycetoma were the main underlying causes. In 21 patients (11%, no cause was identified. A first-line bronchial arteriography was attempted in 147 patients (75%, whereas 46 (23% received conservative treatment. Patients who underwent BAE had a higher respiratory rate, greater amount of bleeding, persistent bloody sputum and/or evidence of active bleeding on fiberoptic bronchoscopy. When completed (n = 131/147, BAE controlled haemoptysis in 80% of patients, both in the short and long (> 30 days terms. Surgery was mostly performed when bronchial arteriography had failed and/or bleeding recurred early after completed BAE. Bleeding was controlled by conservative measures alone in 44 patients. The ICU mortality rate was low (4%. Conclusion Patients with evidence of more severe or persistent haemoptysis were more likely to receive BAE rather than conservative management. The procedure was effective and safe in most patients with severe haemoptysis, and surgery was mostly reserved to failure of arteriography and/or early recurrences after BAE.

    Introduction Maternal mortality is a potentially preventable public health issue. Maternal morbidity is increasingly of interest to aid the reduction of maternal mortality. Obstetric patients admitted to the intensive care unit (ICU) are an important part of the global burden of maternal morbidity. Social determinants influence health outcomes of pregnant women. Additionally, intimate partner violence has a great negative impact on women's health and pregnancy outcome. However, little is known about the contextual and social aspects of obstetric patients treated in the ICU. This study aimed to conduct a systematic review of the social determinants and exposure to intimate partner violence of obstetric patients admitted to an ICU. Methods and analysis A systematic search will be conducted in MEDLINE, CINAHL, ProQuest, LILACS and SciELO from 2000 to 2016. Studies published in English and Spanish will be identified in relation to data reporting on social determinants of health and/or exposure to intimate partner violence of obstetric women, treated in the ICU during pregnancy, childbirth or within 42 days of the end of pregnancy. Two reviewers will independently screen for study eligibility and data extraction. Risk of bias and assessment of the quality of the included studies will be performed by using the Critical Appraisal Skills Programme (CASP) checklist. Data will be analysed and summarised using a narrative description of the available evidence across studies. This systematic review protocol will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines. Ethics and dissemination Since this systematic review will be based on published studies, ethical approval is not required. Findings will be presented at La Trobe University, in Conferences and Congresses, and published in a peer-reviewed journal. Trial registration number CRD42016037492. PMID:27895065

    Full Text Available Background: Computerized medical information systems have been popularized over the last two decades to improve quality and safety, and for decreasing medical errors. Aim: To develop a clinician-friendly computer-based support system in the intensive care unit (ICU that incorporates recording, reminders, alerts, checklists and diagnostic differentials for common conditions encountered in critical care. Materials and Methods: This project was carried out at the Medical ICU CMC Hospital, Vellore, in collaboration with the Computer Science Department, VIT University. The first phase was to design and develop monitoring and medication sheets. Terminologies such as checklists (intervention list that pops up at defined times for all patients, reminders (intervention unique to each patient and alerts (time-based, value-based, trend-based were defined. The diagnostic and intervention bundles were characterized in the second phase. The accuracy and reliability of the software to generate alerts, reminders and diagnoses was tested in the third phase. The fourth phase will be to integrate this with the hospital information system and the bedside monitors. Results: Alpha testing was performed using six scenarios written by intensivists. The software generated real-time alerts and reminders and provided diagnostic differentials relevant to critical care. Predefined interventions for each diagnostic possibility appeared as pop-ups. Problems identified during alpha testing were rectified prior to beta testing. Conclusions: The use of a computer-assisted monitoring, recording and diagnostic system appears promising. It is envisaged that further software refinements following beta testing would facilitate the improvement of quality and safety in the critical care environment.

  6. Performance Measurement and Faculty Pay

    In classic agency models, first best efficiency can't be achieved due to the trade-off between risk and incentives except that agency is risk neutral. Whereas if the principal's objective is not contractible,an alternative objective performance measurement which is contractible is always proposed. However, if the reaction of this objective performance measurement to agency's effort differs from that of the principal's objective, the agent would game performance measures, which leads to loss of efficiency, even if agency is risk neutral. By adding subjective weights on objective measures, or combination of subjective performance measurement with objective performance measurement, efficiency can be regained. Implications for faculty pay are also discussed.

    Full Text Available A task of evaluation of program performance often occurs in the process of design of computer systems or during iterative compilation. A traditional way to solve this problem is emulation of program execution on the target system. A modern alternative approach to evaluation of program performance is based on statistical modeling of program performance on a computer under investigation. This statistical method of modeling program performance called Velocitas was introduced in this work. The method and its implementation in the Adaptor framework were presented. Investigation of the method's effectiveness showed high adequacy of program performance prediction.

    2003-01-01

    The relationship between global performance of a typical helicopter and the airfoil environment, as represented by the airfoil angles of attack and Mach number, has been examined using the comprehensive analysis CAMRAD II. A general correspondence is observed between global performance parameters, such as rotor L/D, and airfoil performance parameters, such as airfoil L/D, the drag bucket boundaries, and the divergence Mach number. Effects of design parameters such as blade twist and rotor speed variation have been examined and, in most cases, improvements observed in global performance are also observed in terms of airfoil performance. The relations observed between global Performance and the airfoil environment suggests that the emphasis in airfoil design should be for good L/D, while the maximum lift coefficient performance is less important.

  10. Musical Formalism and Political Performances

    Jonathan A. Neufeld

    2009-01-01

    Full Text Available Musical formalism, which strictly limits the type of thing any description of the music can tell us, is ill-equipped to account for contemporary performance practice. If performative interpretations are in a position to tell us something about musical works—that is if performance is a kind of description, as Peter Kivy argues—then we have to loosen the restrictions on notions of musical relevance to make sense of performance. I argue that musical formalism, which strictly limits the type of thing any description of the music can tell us, is inconsistent with Kivy's quite compelling account of performance. This shows the difficulty that actual performances pose to overly rigid conceptions of music. Daniel Barenboim's unannounced performance of Wagner in Israel in 2001 shows that the problem of the boundaries of musical relevance is no mere philosophical puzzle. It is a pressing problem in the musical public sphere.

    Findley, H M; Giles, W F; Mossholder, K W

    2000-08-01

    Because appraisal-related interactions between supervisors and employees may influence more than task performance, the authors considered the potential effects of social and interpersonal processes in performance appraisal on contextual performance. They hypothesized that performance appraisal process and system facets were associated with employees' contextual performance as well as with their perceptions of appraisal accuracy. After controlling relevant variables, they found that appraisal process facets explained variance in contextual performance and perceived accuracy beyond that accounted for by the system facets. However, when the order of entry for the process and system variable sets was reversed, only for perceived appraisal accuracy, as hypothesized, did the system facets account for variance beyond that explained by the appraisal process facets.

  15. Operator performance in non-destructive testing: A study of operator performance in a performance test

    In the process industries there is a need of inspecting the integrity of critical components without disrupting the process. Such in-service inspections are typically performed with non-destructive testing (NDT). In NDT the task of the operator is to (based on diagnostic information) decide if the component can remain in service or not. The present study looks at the performance in NDT. The aim is to improve performance, in the long run, by exploring the operators' decision strategies and other underlying factors and to this way find out what makes some operators more successful than others. Sixteen operators performed manual ultrasonic inspections of four test pieces with the aim to detect (implanted) cracks. In addition to these performance demonstration tests (PDT), the operators performed independent ability tests and filled out questionnaires. The results show that operators who trust their gut feeling more than the procedure (when the two come to different results) and that at the same time have a positive attitude towards the procedure have a higher PDT performance. These results indicate the need for operators to be motivated and confident when performing NDT. It was also found that the operators who performed better rated more decision criteria higher in the detection phase than the operators who performed worse. For characterizing it was the other way around. Also, the operators who performed better used more time, both detecting and characterizing, than the operators who performed worse.

    The aim of the study was to assess whether adults admitted to hospitals with both Intensive Care Units (ICU) and Intermediate Care Units (IMCU) have lower in-hospital mortality than those admitted to ICUs without an IMCU. An observational multinational cohort study performed on patients admitted to participating ICUs during a four-week period. IMCU was defined as any physically and administratively independent unit open 24 hours a day, seven days a week providing a level of care lower than an ICU but higher than a ward. Characteristics of hospitals, ICUs and patients admitted to study ICUs were recorded. The main outcome was all-cause in-hospital mortality until hospital discharge (censored at 90 days). One hundred and sixty-seven ICUs from 17 European countries enrolled 5,834 patients. Overall, 1,113 (19.1%) patients died in the ICU and 1,397 died in hospital, with a total of 1,397 (23.9%) deaths. The illness severity was higher for patients in ICUs with an IMCU (median Simplified Acute Physiology Score (SAPS) II: 37) than for patients in ICUs without an IMCU (median SAPS II: 29, P hospital characteristics, the odds ratio of mortality was 0.63 (95% CI 0.45 to 0.88, P = 0.007) in favour of the presence of IMCU. The protective effect of the IMCU was absent in patients who were admitted for basic observation, for example, after surgery (odds ratio 1.15, 95% CI 0.65 to 2.03, P = 0.630) but was strong in patients admitted to an ICU for other reasons (odds ratio 0.54, 95% CI 0.37 to 0.80, P = 0.002). The presence of an IMCU in the hospital is associated with significantly reduced adjusted hospital mortality for adults admitted to the ICU. This effect is relevant for the patients requiring full intensive treatment. Clinicaltrials.gov NCT01422070. Registered 19 August 2011.

    Full Text Available Background: The patient-ventilator asynchrony is almost observed in all modes of ventilation, and this asynchrony affects lung mechanics adversely resulting in deleterious outcome. Innovations and advances in ventilator technology have been trying to overcome this problem by designing newer modes of ventilation. Pressure support ventilation (PSV is a commonly used flow-cycled mode where a constant pressure is delivered by ventilator. Proportional assist ventilation (PAV is a new dynamic inspiratory pressure assistance and is supposed to be better than PSV for synchrony and tolerance, but reports are still controversial. Moreover, most of these studies are conducted in chronic obstructive pulmonary disease patients with respiratory failure; the results of these studies may not be applicable to surgical patients. Thus, we proposed to do compare these two modes in surgical Intensive Care Unit (ICU patients as a randomized crossover study. Aims: Comparison of patient-ventilator asynchrony between PSV and PAV plus (PAV+ in surgical patients while weaning. Subjects and Methods: After approval by the Hospital Ethics Committee, we enrolled twenty patients from surgical ICU of tertiary care institute. The patients were ventilated with pressure support mode (PSV and PAV+ for 12 h as a crossover from one mode to another after 6 h while weaning. Results: Average age and weight of patients were 41.80 ± 15.20 years (mean ± standard deviation [SD] and 66.50 ± 12.47 (mean ± SD kg, respectively. Comparing the asynchronies between the two modes, the mean number of total asynchronous recorded breaths in PSV was 7.05 ± 0.83 and 4.35 ± 5.62, respectively, during sleep and awake state, while the same were 6.75 ± 112.24 and 10.85 ± 11.33 in PAV+. Conclusion: Both PSV and PAV+ modes of ventilation performed similarly for patient-ventilator synchrony in surgical patients. In surgical patients with acute respiratory failure, dynamic inspiratory pressure

    We propose a novel high-performance hardware architecture of processor for elliptic curve scalar multiplication based on the Lopez-Dahab algorithm over GF(2163) in polynomial basis representation. The processor can do all the operations using an efficient modular arithmetic logic unit, which includes an addition unit, a square and a carefully designed multiplication unit. In the proposed architecture, multiplication, addition, and square can be performed in parallel by the decomposition of computation. The point addition and point doubling iteration operations can be performed in six multiplications by optimization and solution of data dependency. The implementation results based on Xilinx Virtexll XC2V6000 FPGA show that the proposed design can do random elliptic curve scalar multiplication GF(2163) in 34.11 μs, occupying 2821 registers and 13 376 LUTs.

    , resistance has been noticed among ICU staff to applying physical training. The purpose of this study was to perform a literature review on the implications of pulmonary rehabilitation programs in the ICU. Articles were sought for in PubMed, Cochane, PEDro and SciELO databases, by means of key words"pulmonary rehabilitation", "intensive care", and"intensive therapy", in addition to studies suggested by experts. Seven articles (randomised clinical trials, cohort, and retrospective studies were assessed. All of them suggested benefits by pulmonary rehabilitation in the ICU, in addition to the absence of side effects. Main benefits were ambulation improvement, increase on strength of respiratory and skeletal muscles, plus improvement in activities of daily living. According to the studies analyzed, pulmonary rehabilitation in the ICU proves to be beneficial to patients, being a safe and well tolerated means of rehabilitation.

    2002-10-30

    We herein present the synthesis, crystal structure, and magnetic properties of a new heterometallic chain of MnIII and NiII ions, [Mn2(saltmen)2Ni(pao)2(py)2](ClO4)2 (1) (saltmen2- = N,N'-(1,1,2,2-tetramethylethylene) bis(salicylideneiminate) and pao- = pyridine-2-aldoximate). The crystal structure of 1 was investigated by X-ray crystallographic analysis: compound 1 crystallized in monoclinic, space group C2/c (No. 15) with a = 21.140(3) A, b = 15.975(1) A, c = 18.6212(4) A, beta = 98.0586(4) degrees , V = 6226.5(7) A3, and Z = 4. This compound consists of two fragments, the out-of-plane dimer [Mn2(saltmen)2]2+ as a coordination acceptor building block and the neutral mononuclear unit [Ni(pao)2(py)2] as a coordination donor building block, forming an alternating chain having the repeating unit [-Mn-(O)2-Mn-ON-Ni-NO-]n. In the crystal structure, each chain is well separated with a minimum intermetallic distance between Mn and Ni ions of 10.39 A and with the absence of interchain pi overlaps between organic ligands. These features ensure a good magnetic isolation of the chains. The dc and ac magnetic measurements were performed on both the polycrystalline sample and the aligned single crystals of 1. Above 30 K, the magnetic susceptibility of this one-dimensional compound was successfully described in a mean field approximation as an assembly of trimers (Mn...Ni...Mn) with a NiII...MnIII antiferromagnetic interaction (J = -21 K) connected through a ferromagnetic MnIII...MnIII interaction (J'). However, the mean field theory fails to describe the magnetic behavior below 30 K emphasizing the one-dimensional magnetic character of the title compound. Between 5 and 15 K, the susceptibility in the chain direction was fitted to a one-dimensional Ising model leading to the same value of J'. Hysteresis loops are observed below 3.5 K, indicating a magnet-type behavior. In the same range of temperature, combined ac and dc measurements show a slow relaxation of the magnetization

  3. Music in Kamigata Rakugo Performance

    Directory of Open Access Journals (Sweden)

    Catherine Hallett

    2014-01-01

    Full Text Available Rakugo is the Japanese tradition of staged comic storytelling presented by highly trained hanashika storytellers associated with small urban variety theatres called yose, found in the Kamigata and Edo regions. Although yose theatres are associated with spoken rather than musical events, music is an integral component of Kamigata rakugo performance. It is central both to the rendering of a storyteller’s performance and to creating the overall atmosphere in the yose theatre. This paper addresses the lack of detailed research on music in Kamigata rakugo performance, particularly in English. It demonstrates and documents the centrality of music in Kamigata rakugo performance, specifically the way that this music, which is rich in symbolism, aids a storyteller’s performance and is intrinsically bound up in the hierarchical structure of the storytellers and yose-bayashi ensemble musicians. It focuses on how the music functions in the performances, transmitting meanings and supporting the social structure of the ensemble.

    2017-04-01

    High performance control systems (HPCS) are advanced damping systems capable of high damping performance over a wide frequency bandwidth, ideal for mitigation of multi-hazards. They include active, semi-active, and hybrid damping systems. However, HPCS are more expensive than typical passive mitigation systems, rely on power and hardware (e.g., sensors, actuators) to operate, and require maintenance. In this paper, a life cycle cost analysis (LCA) approach is proposed to estimate the economic benefit these systems over the entire life of the structure. The novelty resides in the life cycle cost analysis in the performance based design (PBD) tailored to multi-level wind hazards. This yields a probabilistic performance-based design approach for HPCS. Numerical simulations are conducted on a building located in Boston, MA. LCA are conducted for passive control systems and HPCS, and the concept of controller robustness is demonstrated. Results highlight the promise of the proposed performance-based design procedure.

  19. Long-Term Carbon Injection Field Test for 90% Mercury Removal for a PRB Unit a Spray Dryer and Fabric Filter

    2009-04-30

    results of this project also filled a data gap for plants firing PRB coal and configured with an SCR, SDA, and FF, as many new plants are being designed today. Another goal of the project was to evaluate, on a short-term basis, the mercury removal associated with coal additives and coal blending with western bituminous coal. The additive test showed that, at this site, the coal additive known as KNX was affective at increasing mercury removal while decreasing sorbent usage. Coal blending was conducted with two different western bituminous coals, and West Elk coal increased native capture from nominally 10% to 50%. Two additional co-benefits were discovered at this site. First, it was found that native capture increased from nominally 10% at full load to 50% at low load. The effect is believed to be due to an increase in mercury oxidation across the SCR caused by a corresponding decrease in ammonia injection when the plant reduces load. Less ammonia means more active oxidation sites in the SCR for the mercury. The second co-benefit was the finding that high ammonia concentrations can have a negative impact on mercury removal by powdered activated carbon. For a period of time, the plant operated with a high excess of ammonia injection necessitated by the plugging of one-third of the SCR. Under these conditions and at high load, the mercury control system could not maintain 90% removal even at the maximum feed rate of 3.5 lb/MMacf (pounds of mercury per million actual cubic feet). The plant was able to demonstrate that mercury removal was directly related to the ammonia injection rate in a series of tests where the ammonia rate was decreased, causing a corresponding increase in mercury removal. Also, after the SCR was refurbished and ammonia injection levels returned to normal, the mercury removal performance also returned to normal. Another goal of the project was to install a commercial-grade activated carbon injection (ACI) system and integrate it with new

    Full Text Available The improvement of managerial decisions, the identification and the implementation of strategic niches allow the achievement of some performance higher levels, thus ensuring the stability of the organization and the consolidation of the position on the market, which is occupied. The analysis of a company evolution can demonstrate the importance of the integration of the performance measurement system within the objectives of the enterprise on long term, in order to use it as a warning system when the results obtained diverge from the established trajectory. As shown in the synthesis of the selected company evolution, the performance of the company isn't resumed, in a simplistic way, to superior financial-accounting results, to the stable financial equilibrium, to the capacity to generate the cash-flow needed in order to function and to be extended in perspective, but it aims all the non-financial and financial aspects of its activity. In-depth, understanding the performance term, the criteria which have to fulfil a company in order to be efficient, open new opportunities for managers, challenge them to improve new strategies of action. Each criterion shall submit to management a new area of interest, whose good management depend the marketing and development of the company. Given our aim/goal to demonstrate through a practical case how achieving and maintaining performance may be associated with a state of equilibrium, we can summarize the performance stability of a company in two words ”remanent performance” . The remanence quality distinguishes a short-term strategy from a long term strategy, between performance achievement and maintenance of a company’s performance. Remanence expresses that side of performance, consequence of a strategic, continuous, adaptive and proactive process.

    2008-01-01

    Full Text Available In this paper, we describe the construct of citizenship performance and briefly review some of the industrial and organizational psychology research on organizational citizenship. We discuss the history, the dimensionality, the antecedents, consequences and implications for practice, and also provide a critical analysis. The conclusions of this review are that citizenship performance is important for contemporary organizations and contemporary trends suggest it will continue to be important in the future. We encourage further research in the area of citizenship performance in other cultures beyond the US.

  12. Verifiable Network-Performance Measurements

    Argyraki, Katerina; Singla, Ankit

    2010-01-01

    In the current Internet, there is no clean way for affected parties to react to poor forwarding performance: when a domain violates its Service Level Agreement (SLA) with a contractual partner, the partner must resort to ad-hoc probing-based monitoring to determine the existence and extent of the violation. Instead, we propose a new, systematic approach to the problem of forwarding-performance verification. Our mechanism relies on voluntary reporting, allowing each domain to disclose its loss and delay performance to its neighbors; it does not disclose any information regarding the participating domains' topology or routing policies beyond what is already publicly available. Most importantly, it enables verifiable performance measurements, i.e., domains cannot abuse it to significantly exaggerate their performance. Finally, our mechanism is tunable, allowing each participating domain to determine how many resources to devote to it independently (i.e., without any inter-domain coordination), exposing a control...

  13. Psychological factors affecting equine performance

    Directory of Open Access Journals (Sweden)

    McBride Sebastian D

    2012-09-01

    Full Text Available Abstract For optimal individual performance within any equestrian discipline horses must be in peak physical condition and have the correct psychological state. This review discusses the psychological factors that affect the performance of the horse and, in turn, identifies areas within the competition horse industry where current behavioral research and established behavioral modification techniques could be applied to further enhance the performance of animals. In particular, the role of affective processes underpinning temperament, mood and emotional reaction in determining discipline-specific performance is discussed. A comparison is then made between the training and the competition environment and the review completes with a discussion on how behavioral modification techniques and general husbandry can be used advantageously from a performance perspective.

  14. HYPERBARIC OXYGENATION AND AEROBIC PERFORMANCE

    Full Text Available The continuing desire to improve performance, particularly at the national and international levels, has led to the use of ergogenic aids. Ergogenic aids are defined as 'a procedure or agent that provides the athlete with a competitive edge beyond that obtained via normal training methods'. Random drug testing has been implemented in an effort to minimize an athlete's ability to gain an unfair advantage. However, other means of improving performance have been tried. Blood doping has been used to enhance endurance performance by improving oxygen delivery to working muscles. As oxygen is carried in combination with the hemoglobin, it seems logical that increasing the number of red blood cells (RBC's in the body would increase the oxygen carrying capacity to the tissues and result in improved performance. The first experiments of removing and then reinfusing blood showed a significant improvement in performance time

  16. Performative Social Science and Psychology

    Directory of Open Access Journals (Sweden)

    Mary Gergen

    2010-11-01

    Full Text Available This article presents an overview of "Performative Social Science," which is defined as the deployment of different forms of artistic performance in the execution of a scientific project. Such forms may include art, theater, poetry, music, dance, photography, fiction writing, and multi-media applications. Performative research practices are in their developmental stage, with most of the major work appearing in the last two decades. Frequently based on a social constructionist metatheory, supporters reject a realist, or mapping view of representation, and explore varieties of expressive forms for constructing worlds relevant to the social sciences. The performative orientation often relies on a dramaturgical approach that encompasses value-laden, emotionally charged topics and presentations. Social scientists invested in social justice issues and political perspectives have been especially drawn to this approach. Performative social science invites productive collaborations among various disciplinary fields and between the sciences and arts. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1101119

    The technology performance level (TPL) assessments can be applied at all technology development stages and associated technology readiness levels (TRLs). Even, and particularly, at low TRLs the TPL assessment is very effective as it, holistically, considers a wide range of WEC attributes that determine the techno-economic performance potential of the WEC farm when fully developed for commercial operation. The TPL assessment also highlights potential showstoppers at the earliest possible stage of the WEC technology development. Hence, the TPL assessment identifies the technology independent “performance requirements.” In order to achieve a successful solution, the entirety of the performance requirements within the TPL must be considered because, in the end, all the stakeholder needs must be achieved. The basis for performing a TPL assessment comes from the information provided in a dedicated format, the Technical Submission Form (TSF). The TSF requests information from the WEC developer that is required to answer the questions posed in the TPL assessment document.

  20. OVERALL PERFORMANCE - BY CREATING VALUE

    2014-11-01

    Full Text Available Performance has received a fundamental role in an organization's framework given the context in which the competition for each market segment has become even tighter, and the globalization mechanisms eliminates the weaker ones. Performance doesn't require only measurement, but also has to be managed. Taking into consideration the evolution of aforementioned macro-economics it would develop the global performance, which meets besides the economical aspects, the social and environmental ones. The organizations have to face three types of key challenges when it comes to performance measurement: inclusion in the determination process of multiple framework measurements, with multiple indicators, the lack of uniform definitions, but also the lack of consistent applications - all these lead to a variable and trust-lacking measurement of a sustainable performance.
