    Background: One important factor in growth, progress, and increase in work efficiency of employees of any enterprise is to make considerable effort. Supreme leader of the Islamic Republic of Iran also addressed the issue of need for more efforts. The goal of this study was to determine the association of perceived organizational justice and organizational expectations with efforts of nurses to provide a suitable model. Materials and Methods: The current study was a descriptive study. The study group consists of all nurses who worked in hospitals of Isfahan. Due to some limitations all nurses of the special unit, surgery wards and operating room were questioned. The data collection tools were the Organizational Justice Questionnaire, organizational expectations questionnaire, and double effort questionnaire. Content validity of the mentioned questionnaires was confirmed after considering the experts’ comments. The reliability of these questionnaires, using the Cronbach’s alpha, were 0.79, 0.83 and 0.92, respectively. The Pearson correlation and the structural equation model were used for the analysis of data. Findings There was a significant correlation between the perceived organizational justice and the double effort of nurses during the surgery of patients. Correlation of the expectation from job, usefulness of job, and its attractiveness with double effort of nurses before the surgery was also statistically significant. Moreover, it was shown that the root of the mean square error of estimation (RMSEA) was 0.087, the fitted goodness index (GFI) was 0.953, the value of chi-square was 268.5, and the model was statistically significant (p < 0.001). Conclusions: Today Justice is an essential need for human life and its importance in organizations and social life of individuals is evident. PMID:23833614

  5. Expected performance of m-solution backtracking

    1986-01-01

    This paper derives upper bounds on the expected number of search tree nodes visited during an m-solution backtracking search, a search which terminates after some preselected number m problem solutions are found. The search behavior is assumed to have a general probabilistic structure. The results are stated in terms of node expansion and contraction. A visited search tree node is said to be expanding if the mean number of its children visited by the search exceeds 1 and is contracting otherwise. It is shown that if every node expands, or if every node contracts, then the number of search tree nodes visited by a search has an upper bound which is linear in the depth of the tree, in the mean number of children a node has, and in the number of solutions sought. Also derived are bounds linear in the depth of the tree in some situations where an upper portion of the tree contracts (expands), while the lower portion expands (contracts). While previous analyses of 1-solution backtracking have concluded that the expected performance is always linear in the tree depth, the model allows superlinear expected performance.

    2012-01-01

    The Magnetospheric Multiscale (MMS) mission consists of four formation-flying spacecraft placed in highly eccentric elliptical orbits about the Earth. The primary scientific mission objective is to study magnetic reconnection within the Earth s magnetosphere. The baseline navigation concept is the independent estimation of each spacecraft state using GPS pseudorange measurements (referenced to an onboard Ultra Stable Oscillator) and accelerometer measurements during maneuvers. State estimation for the MMS spacecraft is performed onboard each vehicle using the Goddard Enhanced Onboard Navigation System, which is embedded in the Navigator GPS receiver. This paper describes the latest efforts to characterize expected navigation flight performance using upgraded simulation models derived from recent analyses.

  8. An opportunity cost model of subjective effort and task performance

    2013-01-01

    Why does performing certain tasks cause the aversive experience of mental effort and concomitant deterioration in task performance? One explanation posits a physical resource that is depleted over time. We propose an alternate explanation that centers on mental representations of the costs and benefits associated with task performance. Specifically, certain computational mechanisms, especially those associated with executive function, can be deployed for only a limited number of simultaneous tasks at any given moment. Consequently, the deployment of these computational mechanisms carries an opportunity cost – that is, the next-best use to which these systems might be put. We argue that the phenomenology of effort can be understood as the felt output of these cost/benefit computations. In turn, the subjective experience of effort motivates reduced deployment of these computational mechanisms in the service of the present task. These opportunity cost representations, then, together with other cost/benefit calculations, determine effort expended and, everything else equal, result in performance reductions. In making our case for this position, we review alternate explanations both for the phenomenology of effort associated with these tasks and for performance reductions over time. Likewise, we review the broad range of relevant empirical results from across subdisciplines, especially psychology and neuroscience. We hope that our proposal will help to build links among the diverse fields that have been addressing similar questions from different perspectives, and we emphasize ways in which alternate models might be empirically distinguished.

    1987-08-01

    The present study was designed to investigate the effect on performance of the relationship between teacher expectancy and self-expectancy. For the induced expectancy, a random half of 96 high school students enrolled in a four-week summer language course of a Christian association were described to the instructors as having high success potential. The remaining trainees served as controls. Correct scores on the learning task, instructor ratings of behavior and attitude of the instructors were measured on three sessions of the course. Ratings of teacher's behavior were factor-analyzed and four interpretable factors emerged: Support, Caring, Attention, and Tutoring. The induced expectancy and specific levels of self-expectancy had significant effects on the subjects' performance and ratings of the instructor. It was concluded that self-expectancy mediates the effects of teacher expectancy on learning performance. Implications of these results for the Pygmalion effect were discussed. PMID:3450908

    2010-01-01

    Context: Good health is the most important outcome of health care, and healthy life expectancy (HLE), an intuitive and meaningful summary measure combining the length and quality of life, has become a standard in the world for measuring population health. Methods: This article critically reviews the literature and practices around the world for measuring and improving HLE and synthesizes that information as a basis for recommendations for the adoption and adaptation of HLE as an outcome measure in the United States. Findings: This article makes the case for adoption of HLE as an outcome measure at the national, state, community, and health care system levels in the United States to compare the effectiveness of alternative practices, evaluate disparities, and guide resource allocation. Conclusions: HLE is a clear, consistent, and important population health outcome measure that can enable informed judgments about value for investments in health care. PMID:20377757

  15. Ankle moment generation and maximum-effort curved sprinting performance.

    2012-11-15

    Turning at high speed along acute curves is crucial for athletic performance. One determinant of curved sprinting speed is the ground reaction force that can be created by the supporting limb; the moment generated at the ankle joint may influence such force generation. Body lean associated with curved sprints positions the ankle joints in extreme in-/eversion, and may hinder the ankle moment generation. To examine the influence of ankle moment generation on curved sprinting performance, 17 male subjects performed maximum-effort curved sprints in footwear with and without a wedge. The wedged footwear was constructed with the intention to align the ankle joints closer to their neutral frontal-plane configuration during counter-clockwise curved sprints so greater joint moments might be generated. We found, with the wedged footwear, the average eversion angle of the inside leg ankle was reduced, and the plantarflexion moment generation increased significantly. Meanwhile, the knee extension moment remained unchanged. With the wedged footwear, stance-average centripetal ground reaction force increased significantly while no difference in the vertical ground reaction force was detected. The subjects created a greater centripetal ground reaction impulse in the wedged footwear despite a shortened stance phase when compared to the control. Stance-average curved sprinting speed improved by 4.3% with the wedged footwear. The changes in ankle moment and curved sprinting speed observed in the current study supports the notion that the moment generation at the ankle joint may be a performance constraint for curved sprinting.

  18. Expectations developed over multiple timescales facilitate visual search performance

    2015-01-01

    Our perception of the world is strongly influenced by our expectations, and a question of key importance is how the visual system develops and updates its expectations through interaction with the environment. We used a visual search task to investigate how expectations of different timescales (from the last few trials to hours to long-term statistics of natural scenes) interact to alter perception. We presented human observers with low-contrast white dots at 12 possible locations equally spaced on a circle, and we asked them to simultaneously identify the presence and location of the dots while manipulating their expectations by presenting stimuli at some locations more frequently than others. Our findings suggest that there are strong acuity differences between absolute target locations (e.g., horizontal vs. vertical) and preexisting long-term biases influencing observers' detection and localization performance, respectively. On top of these, subjects quickly learned about the stimulus distribution, which improved their detection performance but caused increased false alarms at the most frequently presented stimulus locations. Recent exposure to a stimulus resulted in significantly improved detection performance and significantly more false alarms but only at locations at which it was more probable that a stimulus would be presented. Our results can be modeled and understood within a Bayesian framework in terms of a near-optimal integration of sensory evidence with rapidly learned statistical priors, which are skewed toward the very recent history of trials and may help understanding the time scale of developing expectations at the neural level.

    We recently introduced the idea of self-consistent performance requirements for MPI communication. Such requirements provide a means to ensure consistent behavior of an MPI library, thereby ensuring a degree of performance portability by making it unnecessary for a user to perform implementation-dependent optimizations by hand. For the collective operations in particular, a large number of such rules could sensibly be formulated, without making hidden assumptions about the underlying communication system or otherwise constraining the MPI implementation. In this paper, we extend this idea to the realm of parallel I/O (MPI-IO), where the issues are far more subtle. In particular, it is not always possible to specify performance requirements without making assumptions about the implementation or without a priori knowledge of the I/O access pattern. For such cases, we introduce the notion of performance expectations, which specify the desired behavior for good implementations of MPI-IO. I/O performance requirements as well as expectations could be automatically checked by an appropriate benchmarking tool.

    Human hands play a significant role during extravehicular activity (EVA) missions and Neutral Buoyancy Lab (NBL) training events, as they are needed for translating and performing tasks in the weightless environment. It is because of this high frequency usage that hand- and arm-related injuries and discomfort are known to occur during training in the NBL and while conducting EVAs. Hand-related injuries and discomforts have been occurring to crewmembers since the days of Apollo. While there have been numerous engineering changes to the glove design, hand-related issues still persist. The primary objectives of this study are therefore to: 1) document all known EVA glove-related injuries and the circumstances of these incidents, 2) determine likely risk factors, and 3) recommend ergonomic mitigations or design strategies that can be implemented in the current and future glove designs. METHODS: The investigator team conducted an initial set of literature reviews, data mining of Lifetime Surveillance of Astronaut Health (LSAH) databases, and data distribution analyses to understand the ergonomic issues related to glove-related injuries and discomforts. The investigation focused on the injuries and discomforts of U.S. crewmembers who had worn pressurized suits and experienced glove-related incidents during the 1980 to 2010 time frame, either during training or on-orbit EVA. In addition to data mining of the LSAH database, the other objective of the study was to find complimentary sources of information such as training experience, EVA experience, suit-related sizing data, and hand-arm anthropometric data to be tied to the injury data from LSAH. RESULTS: Past studies indicated that the hand was the most frequently injured part of the body during both EVA and NBL training. This study effort thus focused primarily on crew training data in the NBL between 2002 and 2010. Of the 87 recorded training incidents, 19 occurred to women and 68 to men. While crew ages ranged from thirties to fifties, the age category most affected was in the forties range. Incident rate calculations (incidents per 100 training runs) revealed that the 2002, 2003, and 2004 time periods registered the highest reported incident rate levels (3.4, 6.1, and 4.1 respectively) when compared to the following years (all = 1.0). In addition to general hand-arm discomfort being the highest reported result from training, specific types of hand injuries or symptoms included erythema, fingernail delamination, abrasions, muscle soreness/fatigue, paresthesia, bruising, blanching, and edema. Specific body locations most affected by hand injuries included the metacarpophalangeal joints, fingernails, finger crotches, fingers in general, interphalangeal joints, and fingertips. Causes of injuries reported in the LSAH data were primarily attributed to the forces that the gloved hands were exposed to due to hand intensive tasks and/or poor glove sizing. DISCUSSION: Although the age data indicate that most injuries are reported by male crewmembers in their forties, that is also the dominant gender and age range of most EVA crew therefore it is not an unexpected finding. Age and gender analysis will continue as more details on the uninjured population is accrued. While there is a reasonable mechanism to link training quantity to injury, the results were inconsistent and point to the need for a consistent method of suit-related injury screening and documentation. For instance, the high-incident rate levels for the years 2002 to 2004 could be attributed to a comprehensive medical review of crewmembers post-NBL EVA training that occurred from July 19, 2002 to January 16, 2004. Furthermore, there could have been increased awareness from an investigation at the NBL. These investigations may have temporarily increased the fidelity of reported injuries and discomforts during these dates as compared to surrounding years, when injury signs and symptom were no longer actively being investigated but rather voluntarily reported. Data mining for possible mechanistic factors continues and include

    The Vegetation Canopy Lidar (VCL) mission, expected to launch in the spring of 2002, will carry a unique Multi-Beam Laser Altimeter (MBLA) instrument designed to observe vegetative canopy structure for a nominal mission duration of 2 years. The VCL MBLA is a three-beam instrument where each laser is capable of producing returns with 30-m along-track spacing and 25-m-diameter footprints. Identifying the precise location of the point on the Earth's surface from which the laser energy reflects is a critical issue in the validation and application of the data. The resultant geolocation accuracy is dependent on the performance of many components of the VCL system including: laser pulse round trip travel time observation to surface, navigation tracking data, attitude determination system data, timing, laser pointing and body orientation stability, knowledge of instrument and navigation tracking point positions, media and geophysical corrections. Additionally, it is critical to calibrate on-orbit instrument parameters including pointing and range corrections. The geolocation and calibration methodology and algorithms will be summarized. A detailed geolocation error analysis identifying the contributions from each system component, along with the resultant expected geolocation accuracy, will be presented. A brief discussion of the operational geolocation process will also be presented. Science and data validation implications from geolocation performance will be summarized.

    The Large Hadron Collider (LHC) at CERN promises a major step forward in the understanding of the fundamental nature of matter. The ATLAS experiment is a general-purpose detector for the LHC, whose design was guided by the need to accommodate the wide spectrum of possible physics signatures. The major remit of the ATLAS experiment is the exploration of the TeV mass scale where groundbreaking discoveries are expected. In the focus are the investigation of the electroweak symmetry breaking and linked to this the search for the Higgs boson as well as the search for Physics beyond the Standard Model. In this report a detailed examination of the expected performance of the ATLAS detector is provided, with a major aim being to investigate the experimental sensitivity to a wide range of measurements and potential observations of new physical processes. An earlier summary of the expected capabilities of ATLAS was compiled in 1999 [1]. A survey of physics capabilities of the CMS detector was published in [2]. The design of the ATLAS detector has now been finalised, and its construction and installation have been completed [3]. An extensive test-beam programme was undertaken. Furthermore, the simulation and reconstruction software code and frameworks have been completely rewritten. Revisions incorporated reflect improved detector modelling as well as major technical changes to the software technology. Greatly improved understanding of calibration and alignment techniques, and their practical impact on performance, is now in place. The studies reported here are based on full simulations of the ATLAS detector response. A variety of event generators were employed. The simulation and reconstruction of these large event samples thus provided an important operational test of the new ATLAS software system. In addition, the processing was distributed world-wide over the ATLAS Grid facilities and hence provided an important test of the ATLAS computing system - this is the origin of the expression 'CSC studies' ('computing system commissioning'), which is occasionally referred to in these volumes. The work reported does generally assume that the detector is fully operational, and in this sense represents an idealised detector: establishing the best performance of the ATLAS detector with LHC proton-proton collisions is a challenging task for the future. The results summarised here therefore represent the best estimate of ATLAS capabilities before real operational experience of the full detector with beam. Unless otherwise stated, simulations also do not include the effect of additional interactions in the same or other bunch-crossings, and the effect of neutron background is neglected. Thus simulations correspond to the low-luminosity performance of the ATLAS detector. This report is broadly divided into two parts: firstly the performance for identification of physics objects is examined in detail, followed by a detailed assessment of the performance of the trigger system. This part is subdivided into chapters surveying the capabilities for charged particle tracking, each of electron/photon, muon and tau identification, jet and missing transverse energy reconstruction, b-tagging algorithms and performance, and finally the trigger system performance. In each chapter of the report, there is a further subdivision into shorter notes describing different aspects studied. The second major subdivision of the report addresses physics measurement capabilities, and new physics search sensitivities. Individual chapters in this part discuss ATLAS physics capabilities in Standard Model QCD and electroweak processes, in the top quark sector, in b-physics, in searches for Higgs bosons, supersymmetry searches, and finally searches for other new particles predicted in more exotic models.

    Human hands play a significant role during Extravehicular Activity (EVA) missions and Neutral Buoyancy Lab (NBL) training events, as they are needed for translating and performing tasks in the weightless environment. Because of this high frequency usage, hand and arm related injuries are known to occur during EVA and EVA training in the NBL. The primary objectives of this investigation were to: 1) document all known EVA glove related injuries and circumstances of these incidents, 2) determine likely risk factors, and 3) recommend interventions where possible that could be implemented in the current and future glove designs. METHODS: The investigation focused on the discomforts and injuries of U.S. crewmembers who had worn the pressurized Extravehicular Mobility Unit (EMU) spacesuit and experienced 4000 Series or Phase VI glove related incidents during 1981 to 2010 for either EVA ground training or in-orbit flight. We conducted an observational retrospective case-control investigation using 1) a literature review of known injuries, 2) data mining of crew injury, glove sizing, and hand anthropometry databases, 3) descriptive statistical analyses, and finally 4) statistical risk correlation and predictor analyses to better understand injury prevalence and potential causation. Specific predictor statistical analyses included use of principal component analyses (PCA), multiple logistic regression, and survival analyses (Cox proportional hazards regression). Results of these analyses were computed risk variables in the forms of odds ratios (likelihood of an injury occurring given the magnitude of a risk variable) and hazard ratios (likelihood of time to injury occurrence). Due to the exploratory nature of this investigation, we selected predictor variables significant at p=0.15. RESULTS: Through 2010, there have been a total of 330 NASA crewmembers, from which 96 crewmembers performed 322 EVAs during 1981-2010, resulting in 50 crewmembers being injured inflight and 44 injured during 11,704 ground EVA training events. Of the 196 glove related injury incidents, 106 related to EVA and 90 to EVA training. Over these 196 incidents, 277 total injuries (126 flight; 151 training) were reported and were then grouped into 23 types of injuries. Of EVA flight injuries, 65% were commonly reported to the hand (in general), metacarpophalangeal (MCP) joint, and finger (not including thumb) with fatigue, abrasion, and paresthesia being the most common injury types (44% of total flight injuries). Training injuries totaled to more than 70% being distributed to the fingernail, MCP joint, and finger crotch with 88% of the specific injuries listed as pain, erythema, and onycholysis. Of these training injuries, when reporting pain or erythema, the most common location was the index finger, but when reporting onycholysis, it was the middle finger. Predictor variables specific to increased risk of onycholysis included: female sex (OR=2.622), older age (OR=1.065), increased duration in hours of the flight or training event (OR=1.570), middle finger length differences in inches between the finger and the EVA glove (OR=7.709), and use of the Phase VI glove (OR=8.535). Differentiation between training and flight and injury reporting during 2002-2004 were significant control variables. For likelihood of time to first onycholysis injury, there was a 24% reduction in rate of reporting for each year increase in age. Also, more experienced crewmembers, based on number of EVA flight or training events completed, were less likely to report an onycholysis injury (3% less for every event). Longer duration events also found reporting rates to occur 2.37 times faster for every hour of length. Crewmembers with larger hand size reported onycholysis 23% faster than those with smaller hand size. Finally, for every 1/10th of an inch increase in difference between the middle finger length and the glove, the rate of reporting increased by 60%. DISCUSSION: One key finding was that the Series 4000 glove had a lower injury risk than the Phase VI, which provides a platform for

  20. The Expected Performance from the NASA OCO-2 Mission

    NASA Astrophysics Data System (ADS)

    Crisp, D.; Eldering, A.; Gunson, M. R.; Pollock, H.

    2013-12-01

    The NASA Orbiting Carbon Observatory-2 (OCO-2) will be launched from Vandenberg Air Force Base on a Delta-II 7320 launch vehicle as early as 1 July 2014. Once deployed in the 705-km Afternoon Constellation (A-Train), it will collect the measurements needed to estimate the column-averaged, atmospheric carbon dioxide (CO2) dry air mole fraction (XCO2) with improved precision, resolution, and coverage. The OCO-2 spacecraft carries and points a 3-channel, imaging, grating spectrometer that collects high resolution spectra of reflected sunlight in the 765 nm O2 A-band and in the CO2 bands centered near 1610 and 2060 nm. These spectral ranges overlap those used by the Japanese Greenhouse gases Observing SATellite (GOSAT) TANSO-FTS, the current standard in space-based XCO2 measurements. The OCO-2 instrument performance was extensively characterized during pre-launch testing, facilitating comparisons with the TANSO-FTS. OCO-2 has slightly lower spectral resolution, but the far wings of its instrument line shape functions decay more rapidly, such that it yields similar spectral contrast within O2 and CO2 bands. The instruments have similar continuum signal to noise ratios (SNR) for bright scenes, but the OCO-2 instrument has higher SNR at low light levels associated with absorption lines or dark surfaces. The OCO-2 spectrometers will collect 24 soundings per second, yielding up to a million soundings per day over the sunlit hemisphere. For routine operations, the OCO-2 instrument boresight will be pointed at the local nadir or at the 'glint spot,' where sunlight is specularly reflected from the surface. Nadir observations provide the best spatial resolution and are expected to yield more cloud-free soundings. Glint observations will have much better SNR over dark, ocean surfaces. The nominal plan is to alternate between glint and nadir observations on successive 16-day ground-track repeat cycles, so that the entire sunlit hemisphere is sampled in both modes at 32-day intervals. The instrument's rapid sampling, small (< 3 km2) sounding footprint, and high SNR, combined with the spacecraft's ability to point the instrument's aperture toward the glint spot over the entire sunlit hemisphere, are expected to provide more complete coverage of the ocean, cloudy regions, and high latitude continents. While the OCO-2 measurement capabilities provide opportunities to improve the XCO2 precision, resolution, and coverage, they also pose some formidable challenges for calibration, retrieval, and validation. To fully exploit this instrument's capabilities, the 24,000 spectral/spatial channels must be cross-calibrated to within a fraction of 1%. Substantial increases in algorithm speed and more efficient data screening techniques are needed to fully utilize the much larger data volume. Finally, a comprehensive validation program will be needed to ensure the accuracy of the retrieved XCO2 estimates. This presentation will summarize the OCO-2 measurement capabilities and observation strategies, and the methods adopted to address these challenges.

    Participants were presented an easy or difficult mental addition task and led to believe that they could win a traditionally masculine incentive by meeting a certain performance standard. As expected, blood pressure and heart rate responses during the work period were stronger under difficult conditions than easy ones among men but low under both difficulty conditions among women. Findings support the suggestion from a conceptual analysis grounded in motivation intensity theory that gender differences in cardiovascular response could be partially understood in terms of effort processes that occur where men and women place different value on available performance incentives.

    The TOPEX/Poseidon (T/P) mission, launched during the summer of 1992, has the requirement that the radial component of its orbit must be computed to an accuracy of 13 cm root-mean-square (rms) or better, allowing measurements of the sea surface height to be computed to similar accuracy when the satellite height is differenced with the altimeter measurements. This will be done by combining precise satellite tracking measurements with precise models of the forces acting on the satellite. The Space Geodesy Branch at Goddard Space Flight Center (GSFC), as part of the T/P precision orbit determination (POD) Team, has the responsibility within NASA for the T/P precise orbit computations. The prelaunch activities of the T/P POD Team have been mainly directed towards developing improved models of the static and time-varying gravitational forces acting on T/P and precise models for the non-conservative forces perturbing the orbit of T/P such as atmospheric drag, solar and Earth radiation pressure, and thermal imbalances. The radial orbit error budget for T/P allows 10 cm rms error due to gravity field mismodeling, 3 cm due to solid Earth and ocean tides, 6 cm due to radiative forces, and 3 cm due to atmospheric drag. A prelaunch assessment of the current modeling accuracies for these forces indicates that the radial orbit error requirements can be achieved with the current models, and can probably be surpassed once T/P tracking data are used to fine tune the models. Provided that the performance of the T/P spacecraft is nominal, the precise orbits computed by the T/P POD Team should be accurate to 13 cm or better radially.

    2016-03-01

    Physical work demands and posture constraint from operating microscopes may adversely affect microsurgeon health and performance. Alternative video displays were developed to reduce posture constraints. Their effects on postures, perceived efforts, and performance were compared with the microscope. Sixteen participants performed microsurgery skill tasks using both stereo and non-stereoscopic microscopes and video displays. Results showed that neck angles were 9-13° more neutral and shoulder flexion were 9-10° more elevated on the video display than the microscope. Time observed in neck extension was higher (30% vs. 17%) and neck movements were 3x more frequent on the video display than microscopes. Ratings of perceived efforts did not differ among displays, but usability ratings were better on the microscope than the video display. Performance times on the video displays were 66-110% slower than microscopes. Although postures improved, further research is needed to improve task performance on video displays. PMID:26585502

    2013-01-01

    The purpose of this study was to investigate the effects of using different types of media on physical performance and perceived exertion. This study was divided into two parts. In Part 1, we examined the effects of different combination of audio and video interventions on physical performance and rating of perceived effort (RPE). We recruited 20 collegiate students who performed a 12-minute cycling task (where they were asked to bike as hard as possible) under 4 conditions (music, video, music and video, and control) in a randomized order. Results indicated participants in the 2 media groups (music & audio) reported a significantly lower score for RPE. In addition, there was also an effect of media type where participants in music condition perceived less effort on the cycling task compared to the video condition. Part 2 examined how music preference influenced physical performance, but used a running task (where they were asked to run as hard as possible), and by recruiting a much larger sample. Seventy-five students were assigned into 5 groups (high preference and high motivation, high preference and low motivation, low preference and low motivation, low preference and high motivation, and control) based on responses on the Brunel Music Rating Inventory (BMRI. Results showed that music preference, but not its motivational quality, had a significant effect on physical performance. Overall, these results show that listening to music, and in particular preferred music increases physical performance and reduces perceived effort. Key Points Among different sensory stimulations, music can enhance physical performance more strongly than video. In addition to the motivational level of the music, music preference can also influence the physical performance of aerobic exercise participants. PMID:24149142

  3. [Choking under pressure: Positive public expectations and performance in a motor task].

    PubMed

    Strauss, B

    1997-01-01

    According to Baumeister (e.g. 1985) "choking under pressure" means showing a suboptimal performance when under pressure, despite a high motivation to perform well. Factors that can exert pressure on performers ("pressure variables") include competition, the reward to be gained, the expectation of negative consequences, the presence of spectators etc. However, "choking" can also occur when public expectations (e.g., of the audience) are positive. Baumeister et al. (1985) showed this in two experiments. In the present study an experimental design (a 2 x 2 design) was developed to examine this question in a sport context. Under various conditions of public expectations ("positive" vs "no") and private expectations ("positive" vs "negative"), 60 university students repeatedly had to do a motor task on a rowing ergometer. The main results were: When the public expects success, but not the performing person, then the level of performance decreases. Under the condition of "public expectation of success" a better performance was only shown when the private and the public expectations corresponded with each other. PMID:9577226

    Objective Type 2 diabetes mellitus (T2DM) is associated with high levels of disability and mortality. Regular exercise prevents premature disability and mortality, but people with T2DM are generally sedentary for reasons that are not fully established. We previously observed that premenopausal women with T2DM report greater effort during exercise than their counterparts without diabetes, as measured by the Rating of Perceived Exertion (RPE) scale. We hypothesized that RPE is greater in older women with T2DM versus no T2DM. Research design and methods We enrolled overweight, sedentary women aged 50–75?years with (n=26) or without T2DM (n=28). Participants performed submaximal cycle ergometer exercise at 30?W and 35% of individually-measured peak oxygen consumption (35% VO2peak). We assessed exercise effort by RPE (self-report) and plasma lactate concentration. Results VO2peak was lower in T2DM versus controls (p=0.003). RPE was not significantly greater in T2DM versus controls (30?W: Control, 10.4±3.2, T2DM, 11.7±2.3, p=0.08; 35% VO2peak: Control, 11.1±0.5, T2DM, 12.1±0.5, p=0.21). However, lactate was greater in T2DM versus controls (p=0.004 at 30?W; p<0.05 at 35% VO2peak). Greater RPE was associated with higher lactate, higher heart rate, and a hypertension diagnosis (p<0.05 at 30?W and 35% VO2peak). Conclusions Taken together, physiological measures of exercise effort were greater in older women with T2DM than controls. Exercise effort is a modifiable and thereby targetable end point. In order to facilitate regular exercise, methods to reduce exercise effort in T2DM should be sought. Trial number NCT00785005. PMID:26464803

  7. Effort, symptom validity testing, performance validity testing and traumatic brain injury

    2014-01-01

    Abstract Background: To understand the neurocognitive effects of brain injury, valid neuropsychological test findings are paramount. Review: This review examines the research on what has been referred to a symptom validity testing (SVT). Above a designated cut-score signifies a ‘passing’ SVT performance which is likely the best indicator of valid neuropsychological test findings. Likewise, substantially below cut-point performance that nears chance or is at chance signifies invalid test performance. Significantly below chance is the sine qua non neuropsychological indicator for malingering. However, the interpretative problems with SVT performance below the cut-point yet far above chance are substantial, as pointed out in this review. This intermediate, border-zone performance on SVT measures is where substantial interpretative challenges exist. Case studies are used to highlight the many areas where additional research is needed. Historical perspectives are reviewed along with the neurobiology of effort. Reasons why performance validity testing (PVT) may be better than the SVT term are reviewed. Conclusions: Advances in neuroimaging techniques may be key in better understanding the meaning of border zone SVT failure. The review demonstrates the problems with rigidity in interpretation with established cut-scores. A better understanding of how certain types of neurological, neuropsychiatric and/or even test conditions may affect SVT performance is needed. PMID:25215453

    2012-03-01

    This study examined the effect of rear-wheel camber on maximal effort wheelchair mobility performance. 14 highly trained wheelchair court sport athletes performed a battery of field tests in 4 standardised camber settings (15°, 18°, 20°, 24°) with performance analysed using a velocometer. 20 m sprint times reduced in 18° (5.89±0.47 s, P=0.011) and 20° camber (5.93±0.47 s, P=0.030) compared with 24° (6.05±0.45 s). Large effect sizes revealed that 18° camber enabled greater acceleration over the first 2 (r=0.53, 95% CI=0.004 to 0.239) and 3 (r=0.59, 95% CI=0.017 to 0.170) pushes compared with 24°. Linear mobility times significantly improved (P?0.05) in 15° (16.08±0.84 s), 18° (16.06±0.97 s) and 20° (16.22±0.84 s) camber compared with 24° (16.62±1.10 s). Although no statistically significant main effect of camber was revealed, large effect sizes (r=0.72, 95% CI=0.066 to 0.250) demonstrated that 18° camber reduced times taken to perform the manoeuvrability drill compared with 15°. It was concluded that 18° camber was the best performing setting investigated given its superior performance for both linear and non-linear aspects of mobility, whereas 24° camber impaired linear performance. This was likely to be due to the greater drag forces experienced. Subsequently, athletes would be recommended to avoid 24° camber and young or inexperienced athletes in particular may benefit from selecting 18° as a starting point due to its favourable performance for all aspects of mobility performance in the current study.

  11. The benefit of expecting no conflict - Stronger influence of self-generated than cue-induced conflict expectations on Stroop performance.

    PubMed

    Kemper, Maike; Gaschler, Robert; Schwager, Sabine; Schubert, Torsten

    2016-01-01

    The role of expectations in sequential adaptation to cognitive conflict has been debated controversially in prior studies. On the one hand, a sequential congruency effect (SCE) has been reported for trials in which participants expect a repetition of conflict level. On the other hand, conflict level expectations vs. the SCE have been shown to develop differentially across runs of trials with the same conflict level, arguing against the theory that the SCE is purely driven by expectation. The current verbal Stroop experiment addresses this controversy by two means. First, we tested which specific type of expectation (cue-induced expectations vs. self-generated predictions) might affect the SCE. Second, we assessed the impact of expectation on the SCE as well as the development of SCE and expectation with congruency level run length in one design. We observed a dissociation between expectations and SCE, demonstrating that the SCE is not exclusively driven by expectations. At the same time, we found evidence that (self-generated) expectations do have an impact on the SCE. Our data document especially high performance for one specific combination of task events: congruent trial accompanied by congruent prediction and conflict level repetition. Our results are in line with theories attributing conflict adaptation effects to the "adaption to the lack of conflict". We discuss our results in a broader context of theories about conflict monitoring. PMID:26649453

  12. Economy of effort in different speaking conditions. II. Kinematic performance spaces for cyclical and speech movements.

    PubMed

    Perkell, Joseph S; Zandipour, Majid

    2002-10-01

    This study was designed to test the hypothesis that the kinematic manipulations used by speakers in different speaking conditions are influenced by kinematic performance limits. A range of kinematic parameter values was elicited by having seven subjects produce cyclical CV movements of lips, tongue blade and tongue dorsum (/ba/, /da/, /ga/), at rates ranging from 1 to 6 Hz. The resulting measures were used to establish speaker- and articulator-specific kinematic performance spaces, defined by movement duration, displacement and peak speed. These data were compared with speech movement data produced by the subjects in several different speaking conditions in the companion study (Perkell et al., 2002). The amount of overlap of the speech data and cyclical data varied across speakers, from almost no overlap to complete overlap. Generally, for a given movement duration, speech movements were larger than cyclical movements, indicating that the speech movements were faster and were produced with greater effort, according to the performance space analysis. It was hypothesized that the cyclical movements of the tongue and lips were slower than the speech movements because they were more constrained by (coupled to) the relatively massive mandible. To test this hypothesis, a comparison was made of cyclical movements in maxillary versus mandibular frames of reference. The results indicate that the cyclical movements were not strongly constrained by mandible movements. The overall results generally indicate that the cyclical task did not succeed in defining the upper limits of kinematic performance spaces within which the speech data were confined. Thus, the hypothesis that performance limits influence speech kinematics could not be tested effectively. The differences between the speech and cyclical movements may be due to other factors, such as differences in speakers' "skill" with the two types of movement, or the size of the movements--the speech movements were larger, probably because of a well-defined target for the primary, stressed vowel.

  17. Participation in multilateral effort to develop high performance integrated CPC evacuated collectors

    1992-05-01

    The University of Chicago Solar Energy Group has had a continuing program and commitment to develop an advanced evacuated solar collector integrating nonimaging concentration into its design. During the period from 1985-1987, some of our efforts were directed toward designing and prototyping a manufacturable version of an Integrated Compound Parabolic Concentrator (ICPC) evacuated collector tube as part of an international cooperative effort involving six organizations in four different countries. This 'multilateral' project made considerable progress towards a commercially practical collector. One of two basic designs considered employed a heat pipe and an internal metal reflector CPC. We fabricated and tested two large diameter (125 mm) borosilicate glass collector tubes to explore this concept. The other design also used a large diameter (125 mm) glass tube but with a specially configured internal shaped mirror CPC coupled to a U-tube absorber. Performance projections in a variety of systems applications using the computer design tools developed by the International Energy Agency (IEA) task on evacuated collectors were used to optimize the optical and thermal design. The long-term goal of this work continues to be the development of a high efficiency, low cost solar collector to supply solar thermal energy at temperatures up to 250 C. Some experience and perspectives based on our work are presented and reviewed. Despite substantial progress, the stability of research support and the market for commercial solar thermal collectors were such that the project could not be continued. A cooperative path involving university, government, and industrial collaboration remains the most attractive near term option for developing a commercial ICPC.

    2015-01-01

    Objective. Stress-reducing therapies help maintain cognitive performance during stress. Aromatherapy is popular for stress reduction, but its effectiveness and mechanism are unclear. This study examined stress-reducing effects of aromatherapy on cognitive function using the go/no-go (GNG) task performance and event related potentials (ERP) components sensitive to stress. The study also assessed the importance of expectancy in aromatherapy actions. Methods. 81 adults were randomized to 3 aroma groups (active experimental, detectable, and undetectable placebo) and 2 prime subgroups (prime suggesting stress-reducing aroma effects or no-prime). GNG performance, ERPs, subjective expected aroma effects, and stress ratings were assessed at baseline and poststress. Results. No specific aroma effects on stress or cognition were observed. However, regardless of experienced aroma, people receiving a prime displayed faster poststress median reaction times than those receiving no prime. A significant interaction for N200 amplitude indicated divergent ERP patterns between baseline and poststress for go and no-go stimuli depending on the prime subgroup. Furthermore, trends for beneficial prime effects were shown on poststress no-go N200/P300 latencies and N200 amplitude. Conclusion. While there were no aroma-specific effects on stress or cognition, these results highlight the role of expectancy for poststress response inhibition and attention. PMID:25802539

    2011-06-01

    Research has shown that 2 major facets of perfectionism can be differentiated: perfectionistic strivings and perfectionistic concerns. In order to investigate how these different facets of perfectionism are related to coping, effort, achievement, and performance anxiety in musicians, we asked 275 professional and amateur Japanese musicians to complete measures of perfectionism traits, perfectionism cognitions, coping style, effort, achievement, and performance anxiety. While both facets of perfectionism showed a similar pattern of correlation with coping measures, they were differently associated with effort, achievement, and performance anxiety. In addition, results of hierarchical regression analysis showed the incremental validity of perfectionism cognitions in explaining variance in performance anxiety above the variance explained by other variables, such as trait perfectionism. These findings demonstrate that perfectionism in musicians has both positive and negative elements. PMID:21477982

  2. When sad groups expect to meet again: interactive affective sharing and future interaction expectation as determinants of work groups' analytical and creative task performance.

    PubMed

    2013-12-01

    The present study examines the moderating role of future interaction expectation in the relationship between affective sharing and work groups' task performance. We argue that group affect, a group defining characteristic, becomes more salient to its members when it is interactively shared, and that the anticipation of future interaction may strengthen the effects of group defining characteristics on subsequent group member behaviour. As a consequence, interactive sharing (vs. non-interactive sharing) of negative affect is more likely to influence work group outcomes when group members expect to meet again. Results from a laboratory experiment with 66 three-person work groups indeed show that interactively shared (vs. non-interactively shared) negative affect facilitated work groups' analytical task performance, whereas it inhibited performance on a creative fluency task when groups have expectations of future interaction and not when they do not have such expectations. The discussion focuses on how these results add to theory on group affect and contribute to insights in the effects of future interaction expectation. PMID:23046393

    2010-12-03

    Several lunar missions are planned ahead and there is an increasing demand for efficient photovoltaic power generation in the moon. The knowledge of solar cell operation in the lunar surface obtained during early seventies need to be updated considering current views on solar variability and emerging space solar cell technologies. In this paper some aspects of the solar cell performance expected under variable lunar radiation environment during future space missions to moon are addressed. We have calculated relative power expected from different types of solar cells under extreme solar proton irradiation conditions and high lunar daytime temperature. It is also estimated that 2-3 % of annual solar cell degradation is most probable during the future lunar missions. We have also discussed photovoltaic power generation in long term lunar bases emphasizing technological needs such as sunlight concentration, solar cell cooling and magnetic shielding of radiation for improving the efficiency of solar cells in the lunar environment.

    Effort tests have become commonplace within medico-legal and forensic contexts and their use is rising within clinical settings. It is recognized that some patients may fail effort tests due to cognitive impairment and not because of poor effort. However, investigation of the base rate of failure among clinical populations other than dementia is limited. Forty-seven clinical participants were recruited and comprised three subgroups: acute brain injury (N = 11), community brain injury (N = 20), and intractable epilepsy (N = 16). Base rates of failure on the Word Memory Test (WMT; Green, 2003 ) and six other less well-validated measures were investigated. A significant minority of patients failed effort tests according to standard cutoff scores, particularly patients with severe traumatic brain injury and marked frontal-executive features. The WMT was able to identify failures associated with significant cognitive impairment through the application of profile analysis and/or lowered cutoff levels. Implications for clinical assessment, effort test interpretation, and future research are discussed. PMID:25084843

  6. Non-conscious visual cues related to affect and action alter perception of effort and endurance performance

    The psychobiological model of endurance performance proposes that endurance performance is determined by a decision-making process based on perception of effort and potential motivation. Recent research has reported that effort-based decision-making during cognitive tasks can be altered by non-conscious visual cues relating to affect and action. The effects of these non-conscious visual cues on effort and performance during physical tasks are however unknown. We report two experiments investigating the effects of subliminal priming with visual cues related to affect and action on perception of effort and endurance performance. In Experiment 1 thirteen individuals were subliminally primed with happy or sad faces as they cycled to exhaustion in a counterbalanced and randomized crossover design. A paired t-test (happy vs. sad faces) revealed that individuals cycled significantly longer (178 s, p = 0.04) when subliminally primed with happy faces. A 2 × 5 (condition × iso-time) ANOVA also revealed a significant main effect of condition on rating of perceived exertion (RPE) during the time to exhaustion (TTE) test with lower RPE when subjects were subliminally primed with happy faces (p = 0.04). In Experiment 2, a single-subject randomization tests design found that subliminal priming with action words facilitated a significantly longer TTE (399 s, p = 0.04) in comparison to inaction words. Like Experiment 1, this greater TTE was accompanied by a significantly lower RPE (p = 0.03). These experiments are the first to show that subliminal visual cues relating to affect and action can alter perception of effort and endurance performance. Non-conscious visual cues may therefore influence the effort-based decision-making process that is proposed to determine endurance performance. Accordingly, the findings raise notable implications for individuals who may encounter such visual cues during endurance competitions, training, or health related exercise. PMID:25566014

    The CoRoT space mission, scheduled for launch in December 2006, has two primary science goals: asteroseismology and the detection of planetary transits, the latter being the subject of this contribution. Given its expected photometric performance and its 150 day observing window, CoRoT will detect planets with periods up to 75 days and radii down to 2 Earth radii. To prepare for the data analysis and evaluate the detection limits of the mission, a number of blind exercises to detect planets in simulated light curves have been carried out within the CoRoT exoplanet community, and their results to date are summarized here.

    We study the expected performance of building a neutrino telescope, which targets at energy greater than $10^{14}$ eV utilizing a mountain to interact with neutrinos. The telescope's efficiency in converting neutrinos into leptons is first examined. Then using a potential site on the Big Island of Hawaii, we estimate the acceptance of the proposed detector. The neutrino flux limit at event rate 0.3/year/half decade of energy is estimated to be comparable to that of AMANDA neutrino flux limit at above $10^{16}$ eV.

    During Servicing Mission 3B for the Hubble Space Telescope, a reverse-Brayton cycle turbine cooler will be installed in conjunction with a new external radiator to recool the Near Infrared Camera Multi-Object Spectrometer's (NICMOS) MgCdTe focal plane arrays to operational temperatures of approximately 75K. The new NICMOS Cooling System (NCS) will circulate cold Neon gas through the cooling coils in the NICMOS cryostat (originally used to freeze out the now depleted solid Nitrogen cryogen). Today, NICMOS remains passively functional, and should return to full usability with all observing modes intact with the advent of the NCS. Here, we report on the expectations for the performance of NICMOS once integrated with and cooled by the NCS based on an extensive series of flight and ground experiments and our experience with flight spare detectors operated at these temperatures. We discuss the results from the shuttle-born HOST mission, laboratory experiments at the Steward Observatory NICMOS detector Laboratory emulating the on-orbit warm-up of the detectors, and system level and electro-magnetic susceptibility and interference tests at the Goddard Space Flight Center. From these, and our experience with the NICMOS both during its pre-launch testing and calibration, and on-orbit use during HST Cycle 7, we re-evaluate expectations for systemic read-noise, dark currents, thermal backgrounds, quantum efficiencies, and optical and mechanical stability of the instrument platform. We discuss the expected changes in these characteristics, with respect to HST Cycle 7, both in terms of established performance metrics and their effects on the formulation and conduction of effective observational strategies for conducting NICMOS science observations. This work is supported, in part, by NASA grant NAG5-3042 to the NICMOS Instrument Definition Team.

    2012-02-01

    Successful adaptation to the environment requires the learning of stimulus-response-outcome associations. Such associations can be learned actively by trial and error or by observing the behaviour and accompanying outcomes in other persons. The present study investigated similarities and differences in the neural mechanisms of active and observational learning from monetary feedback using functional magnetic resonance imaging. Two groups of 15 subjects each - active and observational learners - participated in the experiment. On every trial, active learners chose between two stimuli and received monetary feedback. Each observational learner observed the choices and outcomes of one active learner. Learning performance as assessed via active test trials without feedback was comparable between groups. Different activation patterns were observed for the processing of unexpected vs. expected monetary feedback in active and observational learners, particularly for positive outcomes. Activity for unexpected vs. expected reward was stronger in the right striatum in active learning, while activity in the hippocampus was bilaterally enhanced in observational and reduced in active learning. Modulation of activity by prediction error (PE) magnitude was observed in the right putamen in both types of learning, whereas PE related activations in the right anterior caudate nucleus and in the medial orbitofrontal cortex were stronger for active learning. The striatum and orbitofrontal cortex thus appear to link reward stimuli to own behavioural reactions and are less strongly involved when the behavioural outcome refers to another person's action. Alternative explanations such as differences in reward value between active and observational learning are also discussed. PMID:22074898

    2013-01-01

    Existing muon detectors will face new operating challenges after the HL-LHC upgrade, and various actions are planned to mitigate the expected problems. The main issues are muon chambers reaching rate limits, high occupancy, high dead time, and chambers ageing due to radiation or accumulated charge. It being impossible to rebuild an entire muon system even during a long shutdown, only targeted detector upgrades of specific problematic regions are envisaged. In this talk the main issues related to detector and systems longevity will be covered, and the strategies that the different experiments are planning in order to maintain the performance of their systems at the present level in face of the harsher conditions will be outlined.

    A new hadron blind detector (HBD) for electron identification in high density hadron environment has been installed in the PHENIX experiment at RHIC in the fall of 2006. The HBD will identify low momentum electron-positron pairs to reduce the combinatorial background in the e{sup +}e{sup -} mass spectrum, mainly in the region below 1 GeV/c2. The HBD is a windowless proximity-focusing Cherenkov detector with a radiator length of 50 cm, a CsI photocathode and three layers of gas electron multipliers (GEM). Pure CF4 is used as a radiator and a detector gas. This proceeding describes the construction details and the expected performance of the HBD.

    The differentiation among {open_quotes}rightsizing,{close_quotes} {open_quotes}downsizing,{close_quotes} and {open_quotes}reengineering{close_quotes} has been lost by many organizations. Also, unfortunately of late, the approaches to improved competitiveness and worker productivity are being viewed, by many companies, as neither worth the effort nor achieving the desired results. In some cases, the effort may actually create more negative results. This type of negative perception has been documented in a variety of sources that include the following: (1) less than half the companies reporting improvements in operating profits after the cuts were made, (2) the processes resulting in significantly degraded morale among more than 75% of the employees, (3) less than one-third of organizations reporting improvements in worker productivity, and (4) even Michael Hammer (the reengineering {open_quotes}guru{close_quotes}) believing that more than 50% and maybe as much as 70% of the organizations do not achieve the intended results. This paper describes an integrated organizational review process that was applied within a nuclear utility that did achieve the desired results.

    2014-12-01

    The NOAA/DSCOVR satellite is expected to launch in January, 2015 and replace the NASA/ACE satellite as the L1 Sentinel in early Summer, 2015. Having relied on ACE to provide critical warnings of geomagnetic storms since 1998, it is important for the space weather community to understand how DSCOVR will perform relative to ACE in real-time operations. The WIND/SWE instrument is sufficiently similar to the DSCOVR Faraday Cup that it can be used as a proxy for DSCOVR, with some caveats. We compare the ACE/SWEPAM and WIND/SWE observations for all geomagnetic storm events meeting the criteria of severe or extreme. We also examine time periods where ACE data were compromised by solar energetic particles. We find that DSCOVR will provide a more robust data stream than was provided by ACE during solar cycle 23. We will briefly address the magnetometer, supra-thermal particle measurements, and relativistic proton measurements provided by ACE, of which only the magnetometer is retained on DSCOVR. We also demonstrate that lead time for geomagnetic storm notifications to customers far exceeds the L1 to Earth delay time.

    CERN (European Center for Nuclear Research) is a global laboratory that studies proton and heavy ion collisions at the Large Hadron Collider (LHC). ALICE (A Large Ion Collider Experiment) is one of four large experiments of the LHC. ALICE is dedicated to the study of the transition of matter to Quark Gluon Plasma in heavy ion collisions. In the present ALICE detector there are two sub-detectors, (the T0 and V0), that provide minimum bias trigger, multiplicity trigger, beam-gas event rejection, collision time for the Time of Flight detector (TOF), on line multiplicity and event plane determination. In order to adapt these functionalities to the collision rates expected for the LHC upgrade of 2018, it is planned to replace these systems by a single detector system, called the Fast Interaction Trigger (FIT). Two sensor technologies are proposed for FIT, they represent improvements of the current T0 and V0 detectors (T0-Plus and V0-Plus). In this presentation we describe the performance parameters of the FIT upgrade; show the proposed characteristics of the T0-Plus and the simulations that support the conceptual design of this detector. This material is based upon work supported by the National Science Foundation under grants NSF-PHY-0968903 and NSF-PHY-1305280.

    2016-01-01

    To achieve long-pulse tokamak operation, sufficient current drive and self-generated current are required, with the challenges of the exhaust of the heat from the divertor plates. Experiments have proven that lower hybrid current drive (LHCD) can broaden the divertor power footprint and cause the splitting of the strike point current and hence reduce the peak heat flux on the divertors. Edge localized mode (ELM) mitigation can be realized by supersonic molecule beam injection (SMBI), modulated LHCD, lithium granule and aerosol injection, as well as resonant magnetic perturbation (RMP). Enhanced transport by an electrostatic edge coherent mode at the pedestal region is observed in the ELM mitigated plasmas by LHCD. Long-pulse H-mode plasmas in the small ELMy regime have been demonstrated by a combination of ELM mitigation techniques and the optimization of the plasma confinement performance. These newly achieved H-mode scenarios by using features of LHCD in the control of steady-state peak heat flux and transient heat flux due to ELMs may offer a promising regime for further EAST long-pulse high-performance operation and be applicable to ITER.

    Networks of no-take marine reserves (NTMRs) are widely advocated for preserving exploited fish stocks and for conserving biodiversity. We used underwater visual surveys of coral reef fish and benthic communities to quantify the short- to medium-term (5 to 30 years) ecological effects of the establishment of NTMRs within the Great Barrier Reef Marine Park (GBRMP). The density, mean length, and biomass of principal fishery species, coral trout (Plectropomus spp., Variola spp.), were consistently greater in NTMRs than on fished reefs over both the short and medium term. However, there were no clear or consistent differences in the structure of fish or benthic assemblages, non-target fish density, fish species richness, or coral cover between NTMR and fished reefs. There was no indication that the displacement and concentration of fishing effort reduced coral trout populations on fished reefs. A severe tropical cyclone impacted many survey reefs during the study, causing similar declines in coral cover and fish density on both NTMR and fished reefs. However, coral trout biomass declined only on fished reefs after the cyclone. The GBRMP is performing as expected in terms of the protection of fished stocks and biodiversity for a developed country in which fishing is not excessive and targets a narrow range of species. NTMRs cannot protect coral reefs directly from acute regional-scale disturbance but, after a strong tropical cyclone, impacted NTMR reefs supported higher biomass of key fishery-targeted species and so should provide valuable sources of larvae to enhance population recovery and long-term persistence.

    The role of structural shielding mass in the design, verification, and in-flight performance of International Space Station (ISS), in both the natural and induced orbital ionizing radiation (IR) environments, is reported. Detailed consideration of the effects of both the natural and induced ionizing radiation environment during ISS design, development, and flight operations has produced a safe, efficient manned space platform that is largely immune to deleterious effects of the LEO ionizing radiation environment. The assumption of a small shielding mass for purposes of design and verification has been shown to be a valid worst-case approximation approach to design for reliability, though predicted dependences of single event effect (SEE) effects on latitude, longitude, SEP events, and spacecraft structural shielding mass are not observed. The Figure of Merit (FOM) method over predicts the rate for median shielding masses of about 10g/cm(exp 2) by only a factor of 3, while the Scott Effective Flux Approach (SEFA) method overestimated by about one order of magnitude as expected. The Integral Rectangular Parallelepiped (IRPP), SEFA, and FOM methods for estimating on-orbit (Single Event Upsets) SEU rates all utilize some version of the CREME-96 treatment of energetic particle interaction with structural shielding, which has been shown to underestimate the production of secondary particles in heavily shielded manned spacecraft. The need for more work directed to development of a practical understanding of secondary particle production in massive structural shielding for SEE design and verification is indicated. In contrast, total dose estimates using CAD based shielding mass distributions functions and the Shieldose Code provided a reasonable accurate estimate of accumulated dose in Grays internal to the ISS pressurized elements, albeit as a result of using worst-on-worst case assumptions (500 km altitude x 2) that compensate for ignoring both GCR and secondary particle production in massive structural shielding.

    2009-01-01

    Background The purpose of this study was to assess the between-day reliability of the electromechanical delay (EMD) of selected neck muscles during the performance of maximal isometric contractions in five different directions. Methods Twenty-one physically active males participated in two testing sessions separated by seven to eight days. Using a custom-made fixed frame dynamometer, cervical force and surface electromyography (EMG) were recorded bilaterally from the splenius capitis, upper trapezius and sternocleidomastoid muscles during the performance of efforts in extension, flexion, left and right lateral bending, and protraction. The EMD was extracted using the Teager-Kaiser Energy Operator. Reliability indices calculated for each muscle in each testing direction were: the difference in scores between the two testing sessions and corresponding 95% confidence intervals, the standard error of measurement (SEM) and intra-class correlation coefficients (ICC). Results EMD values showed no evidence of systematic difference between the two testing sessions across all muscles and testing directions. The SEM for extension, flexion and lateral bending efforts ranged between 2.5 ms to 4.8 ms, indicating a good level of measurement precision. For protraction, SEM values were higher and considered to be imprecise for research and clinical purposes. ICC values for all muscles across all testing directions ranged from 0.23 to 0.79. Conclusion EMD of selected neck muscles can be measured with sufficient precision for the assessment of neck muscle function in an athletic population in the majority of directions tested.

    Lessons learned from the Atmospheric Infrared Sounder (AIRS) and the Moderate Resolution Imaging Spectroradiometer (MODIS) projects highlight areas where further technology development is needed to address future land, ocean and atmospheric measurement needs. Although not established as requirements at this time, it is anticipated that scientists will expect improvements in the areas of spatial, spectral, radiometric, polarimetric, temporal and calibration performance for future sensors. This paper addresses each of these performance areas and provides lessons learned from MODIS and AIRS. We also present expectations in performance of the system based on information from NASA Instrument Incubator Program and industry reports. Tradeoffs are presented vs orbit altitude (LEO, ME0 and GEO) and provide a 'systems' perspective to future measurement concepts.

    2011-01-01

    Long-term solutions for the disposal of toxic wastes usually involve isolation of the wastes in a deep subsurface geologic environment. In the case of spent nuclear fuel, if radionuclide leakage occurs from the engineered barrier, the geological medium represents the ultimate barrier that is relied upon to ensure safety. Consequently, an evaluation of radionuclide travel times from a repository to the biosphere is critically important in a performance assessment analysis. In this study, we develop a travel time framework based on the concept of groundwater lifetime expectancy as a safety indicator. Lifetime expectancy characterizes the time that radionuclides will spend in the subsurface after their release from the repository and prior to discharging into the biosphere. The probability density function of lifetime expectancy is computed throughout the host rock by solving the backward-in-time solute transport adjoint equation subject to a properly posed set of boundary conditions. It can then be used to defi...

    1992-01-01

    A high resolution telescope for imaging cosmic x ray sources in the MeV region, with an angular resolution better than 0.5 deg is being developed as balloon-borne payload. The instrument consists of a 3-D liquid xenon TPC as x ray detector, coupled with a coded aperture at a distance of 1 meter. A study of the actual source distribution of the 1.809 MeV line from the decay of Al-26 and the 511 keV positron-electron annihilation line is among the scientific objectives, along with a search for new x ray sources. The telescope design parameters and expected minimum flux sensitivity to line and continuum radiation are presented. The unique capablity of the LXe-TPC as a Compton Polarimeter is also discussed.

    Invasive species are a universal global problem, but the information to identify them, manage them, and prevent invasions is stored around the globe in a variety of formats. The Global Invasive Species Information Network is a consortium of organizations working toward providing seamless access to these disparate databases via the Internet. A distributed network of databases can be created using the Internet and a standard web service protocol. There are two options to provide this integration. First, federated searches are being proposed to allow users to search "deep" web documents such as databases for invasive species. A second method is to create a cache of data from the databases for searching. We compare these two methods, and show that federated searches will not provide the performance and flexibility required from users and a central cache of the datum are required to improve performance.

    2008-07-08

    The effects of local geology on ground-motion amplification and building damage were studied in Palestine-West Bank. Nakamura's method of microtremor analysis was applied in this study. The measurements showed significantly higher amplification in the frequency range of building vulnerability in different parts of Nablus city. This finding is consistent with the distribution of the earthquake damage grades in the urban areas struck by the 11 February 2004 earthquake (ML = 5.2) with a focal depth of 17 km beneath the northeastern part of the Dead Sea Basin. Quite large differences in amplification between around 1 and 9 were computed between the eastern and western rims of the city. The downtown built in the central part of the city on soft clay, marl and valley deposits, whereas the northern and southern parts of urban areas in Nablus city lying on mountains consist of consolidated carbonates bedrock. In the central part of the city and at the rims, where the thickness of fluvial deposits and soft formations is about 15 m, amplifications between 6.74 and 8.67 for dominant natural period range of 0.8-1.1 sec were obtained. On the southern and northern mountains, which are located on limestone rocks covered with a thin layer of soil, the amplification in the same frequency range was low. Calculating the natural period of the existing common buildings (T{sub b}) in the studied area (buildings with 10-12 stories), by using the dynamic analysis method. The values of T{sub b} obtained were much closed to the site dominant natural period (Ts). The findings of this study indicate that the expected differences in damage grades for urban areas in Nablus city could be attributed to variations in the thickness and physical properties of Tertiary-Quaternary sediments, which appear to be rather heterogeneous.

  5. Case Study of Expected Seismic Performance of an Instrumented Steel Moment Frame Building

    Amore, Enzo D'; Astaneh-Asl, Abolhassan

    2008-07-08

    A relevant number of modern welded steel structures suffered unexpected damage during the January 1994 Northridge earthquake. The damage of welded special moment resisting frames (W-SMRJF) typically involved the brittle fracture in the welded girder to column connection areas. In the aftermath of the Northridge earthquake the research and structural engineering communities addressed the issue of the seismic safety of damaged and undamaged W-SMRF's. However, even though seismic design codes in the United States were significantly revised after the Northridge quake, still there are hundreds of existing W-Serf's in the US and in other countries, designed and detailed according to pre-Northridge criteria. This work is a case study on seismic response of a W-SMRF instrumented by the California Strong Motion Instrumentation Program (CSMIP) which was shaken during the 1987 Whittier, 1991 Sierra Madre and 1994 Northridge earthquakes. A detailed finite element model of the structure is developed to analyze the building dynamic response during recorded strong motions. Model accuracy was assessed by comparing prediction of the analytical model with actual CSMIP response records. In order to assess its vulnerability in response to future and possibly stronger earthquakes, nonlinear analyses were conducted subjecting the model to the Newhall and Sylmar records of the 1994 Northridge and to the 1995 Kobe earthquakes. Analysis results show that the structure behaved linearly during these earthquakes. The predicted response to larger and more severe ground motions show that plastic deformation occur at many column ends and inelastic deformation demands exceed the expected capacity of the welded pre-Northridge beam-to-column connections.

  6. Special Report on the "Department of Energy's Efforts to Meet Accountability and Performance Reporting Objectives of the American Recovery and Reinvestment Act"

    SciTech Connect

    2009-09-01

    The purpose of the American Recovery and Reinvestment Act of 2009 (Recovery Act) was to jumpstart the U.S. economy, create or save millions of jobs, spur technological advances in health and science, and invest in the Nation's energy future. The Department of Energy will receive an unprecedented $38 billion in Recovery Act funding to support a variety of science, energy, and environmental initiatives. The Recovery Act requires transparency and accountability over these funds. To this end, the Office of Management and Budget (OMB) issued guidance requiring the Department to compile and report a wide variety of funding, accounting, and performance information. The Department plans to leverage existing information systems to develop accounting and performance information that will be used by program managers and ultimately reported to Recovery.gov, the government-wide source of Recovery Act information, and to OMB. The Department's iManage iPortal, a system that aggregates information from a number of corporate systems, will serve as the main reporting gateway for accounting information. In addition, the Department plans to implement a methodology or system that will permit it to monitor information reported directly to OMB by prime funding recipients. Furthermore, performance measures or metrics that outline expected outcomes are being developed, with results ultimately to be reported in a recently developed Department-wide system. Because of the significance of funds provided and their importance to strengthening the Nation's economy, we initiated this review to determine whether the Department had taken the steps necessary to ensure that Recovery Act funds can be appropriately tracked and are transparent to the public, and whether the benefits of the expenditures can be properly measured and reported clearly, accurately, and in a timely manner. Although not yet fully mature, we found that the Department's efforts to develop, refine, and apply the control structure needed to ensure accurate, timely, and reliable reporting to be both proactive and positive. We did, however, identify certain issues relating to Recovery Act performance management, accounting and reporting accuracy, and timeliness that should be addressed and resolved. In particular, at the time of our review: (1) Program officials had not yet determined whether existing information systems will be able to process anticipated transaction increases associated with the Recovery Act; (2) System modifications made to the Department's performance management system to accommodate Recovery Act performance measures had not yet been fully tested and verified; (3) The ability of prime and sub-recipients to properly segregate and report both accounting and performance information had not been determined; (4) There was a lack of coordination between Headquarters organizations related to aspects of Recovery Act reporting. For example, we observed that the Offices of Fossil Energy and Program, Analysis and Evaluation were both involved in developing job creation estimates that could yield significantly different results; and, (5) A significant portion (91 of 142, or 64 percent) of the performance measures developed for the Recovery Act activities were not quantifiable. In some instances, Project Operating Plans had not been finalized and we were not able to verify that all needed performance measures had been developed. Furthermore, the Department had not developed specific metrics to measure federal and contractor jobs creation and retention, an essential Recovery Act objective. The Department had devoted a great deal of time and resources to identifying and mitigating Recovery Act-related risks. For example, the Department developed a risk assessment tool that is intended to assist programs in identifying risks that can prevent its Recovery Act projects from meeting their intended goals. We also found that program staff and management officials at multiple levels were actively engaged in designing Recovery Act-related control and accountability programs. These efforts ra

    A basic bacteriology course was offered in two successive academic years, first in a conventional format and subsequently as a “hybrid” course. The latter combined (i) online presentation of content, (ii) an emphasis on online resources, (iii) thrice-weekly, face-to-face conversations to advance understanding, and (iv) frequent student postings on an electronic discussion board. We compared the two courses through statistical analysis of student performances on the final examinations and the course overall and student assessment of teaching. The data indicated that there was no statistical difference in performance on the final examinations or the course overall. Responses on an instrument of evaluation revealed that students less strongly affirmed the following measures in the hybrid course: (i) The amount of work was appropriate for the credit received, (ii) Interactions between students and instructor were positive, (iii) I learned a great deal in this course, and (iv) I would recommend this course to other students. We recommend clear direction about active learning tasks and relevant feedback to enhance learning in a hybrid course. PMID:23653558

    The Advanced Stirling Radioisotope Generator (ASRG) will enable various missions such as small body sample return, atmospheric missions around Venus, as well as long - duration deep space missions. Analysis of the temperature distributions are performed on an Advanced Stirling Convertor, and the results are compared with available experimental measurements. This analysis includes applied environmental conditions that are similar to those that will be experienced while the convertor is in operation. The applied conditions represent a potential mission profile including pre-takeoff sterilization, launch, transit, and return. The results focus on the anticipated peak temperatures of the magnets in the linear alternator. These results confirm that the ASC can support future missions to deep space targets, extreme environment landers, as well as more conventional goals.

    EXIST is being studied as the Black Hole Finder Probe, one of the 3 Einstein Probe missions under NASA's Beyond Einstein program. The major science goals for EXIST include highly sensitive full-sky hard X-ray survey in a very wide energy band of 5-600 keV. The scientific requirements of wide energy band (10-600 keV for the High Energy Telescope considered for EXIST) and large field of view (approximately 130 deg x 60 deg in the current design, incorporating an array of 18 contiguous very large area coded aperture telescopes) presents significant imaging challenges. The requirement of achieving high imaging sensitivity puts stringent limits on the uniformity and knowledge of systematics for the detector plane. In order to accomplish the ambitious scientific requirements of EXIST, it is necessary to implement many novel techniques. Here we present the initial results of our extensive Monte-Carlo simulations of coded mask imaging for EXIST to estimate the performance degradation due to various factors affecting the imaging such as the non-ideal detector plane and bright partially coded sources.

    Observations of meteors in the atmosphere of the Earth have a long historic tradition and brought up knowledge of meteoroid population and streams in near Earth space (amongst others). Only recently observations of meteoroid impacts on the dark side of the Moon became technically possible. Since the first confirmed Earth based observation of a lunar impact flash in 1999 [e.g.2] more than 50 impact flashes have been registered [1]. Meteoroids bombarding the Moon are not slowed down by an atmosphere and impact with high velocities of up to 70 km/s, causing a light flash of about 10 to 100 ms duration. Continuous observations of the dark hemisphere of the Moon enable the possibility to improve data of the meteoroid population as well as to determine impact time and location which can be used for seismic analysis and interior structure determination. Therefore, it is important to study the various system parameters that determine the possibility of a successful lunar impact flash detection, which we have implemented by numeric simulations. In particular, we want to evaluate the performance of the camera head of the SPOSH camera system [3] attached to a telescope.

    The Insight NASA Discovery mission, led by the Jet Propulsion Laboratory, will deploy in September 2016 a very broadband seismometer on the Mars surface, SEIS (Seismic Experiment for Interior Structure). It is a hybrid 3-axes instrument, which encloses 3 very broadband oblique sensors and 3 short period sensors. The sensor assembly and its wind and thermal shield will by deployed on the Mars surface from the Phoenix-like spacecraft by a robotic arm (IDS). The acquisition system will be hosted in the spacecraft warm electronics box, and connected to the deployed sensor assembly by a tether. The SEIS experiment is provided by CNES, the French Space Agency that makes the coordination of a wide consortium including IPGP of Paris (SEIS PI Institution), Imperial College of London, Oxford University, MPS of Göttingen, ETH of Zürich, ISAE from Toulouse and the Jet Propulsion Laboratory of Pasadena. In addition to the seismometer, the Insight payload will also include a suite of instruments complementary to the seismometer, such as a precision temperature sensor, a micro-barometer, a magnetometer and a wind sensor, making it the first geophysical multi-parameter station on another planet. A heat flow sensor and geodetic measurements will provide additional science measurements, in order to constrain the internal structure of Mars. Several challenges have been overcome to design and realize the planetary seismometer, which will exhibit a noise of about 10-9 m/s2/sqrt(Hz) in its seismic bandwidth bandwidth (0.01-1 Hz) for the very broadband component. These challenges include a very efficient insulation from the external temperature variations, and a finely crafted mechanical design to keep the extreme sensitivity of the seismometer, while allowing enough robustness for the harsh mechanical environment encountered during the launch and landing sequences. Also, specific attention has been paid to understanding the various environment contributions to the noise figure. A discussion will be presented, on how to understand the seismometer performance figure in a changing environment, and how to secure the mission science goals in the challenging environment of the Mars surface.

    NextGen operations are associated with a variety of changes to the national airspace system (NAS) including changes to the allocation of roles and responsibilities among operators and automation, the use of new technologies and automation, additional information presented on the flight deck, and the entire concept of operations (ConOps). In the transition to NextGen airspace, aviation and air operations designers need to consider the implications of design or system changes on human performance and the potential for error. To ensure continued safety of the NAS, it will be necessary for researchers to evaluate design concepts and potential NextGen scenarios well before implementation. One approach for such evaluations is through human performance modeling. Human performance models (HPMs) provide effective tools for predicting and evaluating operator performance in systems. HPMs offer significant advantages over empirical, human-in-the-loop testing in that (1) they allow detailed analyses of systems that have not yet been built, (2) they offer great flexibility for extensive data collection, (3) they do not require experimental participants, and thus can offer cost and time savings. HPMs differ in their ability to predict performance and safety with NextGen procedures, equipment and ConOps. Models also vary in terms of how they approach human performance (e.g., some focus on cognitive processing, others focus on discrete tasks performed by a human, while others consider perceptual processes), and in terms of their associated validation efforts. The objectives of this research effort were to support the Federal Aviation Administration (FAA) in identifying HPMs that are appropriate for predicting pilot performance in NextGen operations, to provide guidance on how to evaluate the quality of different models, and to identify gaps in pilot performance modeling research, that could guide future research opportunities. This research effort is intended to help the FAA evaluate pilot modeling efforts and select the appropriate tools for future modeling efforts to predict pilot performance in NextGen operations.

    The inner drift chamber of the BESIII is encountering serious aging problem after five year's running. For the first layer, the decrease in gas gain is about 26% from 2009 to 2013. The upgrade of the inner tracking detector has become an urgent problem for the BESIII experiment. An inner tracker using CMOS pixel sensors is an important candidate because of its great advantages on spatial resolution and radiation hardness. In order to carry out a Monte Carlo study on the expected performance, a Geant4-based full simulation for the silicon pixel detector has been implemented. The tracking method combining the silicon pixel inner tracker and outer drift chamber has been studied and a preliminary reconstruction software was developed. The Monte Carlo study shows that the performances including momentum resolution, vertex resolution and the tracking efficiency are significantly improved due to the good spatial resolution and moderate material budget of the silicon pixel detector.

    2013-08-01

    The Silicon Vertex Tracker (SVT) of the new SuperB collider will be composed of 6 different detector layers [1]. The innermost layer (L0) will be composed by striplets or pixels [2]; the other 5 detector layers will be double-sided long-strip detectors. The strip geometries and the foreseen hit-rates will change according to the different layers. As a consequence, different optimization of the analog read-out electronics is needed in order to provide high detection-efficiency and low noise level in the different layers. Two readout ASICs are currently developed, one for layers 0-3, another for layers 4 and 5; they differ mainly in the analog front-end. In this work, we present the design and the expected performances of the analog front-end for layers 4 and 5. For these layers, the strip detectors show a very high stray capacitance and high series resistance. In this condition, the noise optimization is our primary concern. A necessary compromise on the best peaking time to achieve an acceptable noise level together with efficiency and timing accuracy has been found. We will present the design of preamplifier and shaper and the results of simulation of noise performance and efficiency (with the expected background rates). In addition, the design of the time-over-threshold and its use to correct the time-walk of the event trigger is discussed as well as the achievable timing accuracy of the circuit.

  19. Performance Expectations of Closed-Brayton-Cycle Heat Exchangers in 100-kWe Nuclear Space Power Systems

    Barrett, Michael J.

    2003-01-01

    Performance expectations of closed-Brayton-cycle heat exchangers to be used in 100-k We nuclear space power systems were forecast. Proposed cycle state points for a system supporting a mission to three of Jupiter's moons required effectiveness values for the heat-source exchanger, recuperator and rejection exchanger (gas cooler) of 0.98, 0.95, and 0.97, respectively. Performance parameters such as number of thermal units (Ntu), equivalent thermal conductance (UA), and entropy generation numbers (Ns) varied from 11 to 19, 23 to 39 kW/K, and 0.019 to 0.023 for some standard heat exchanger configurations. Pressure-loss contributions to entropy generation were significant; the largest frictional contribution was 114% of the heat transfer irreversibility. Using conventional recuperator designs, the 0.95 effectiveness proved difficult to achieve without exceeding other performance targets; a metallic, plate-fin counterflow solution called for 15% more mass and 33% higher pressure-loss than the target values. Two types of gas-coolers showed promise. Single-pass counterflow and multipass cross-counterflow arrangements both met the 0.97 effectiveness requirement. Potential reliability-related advantages of the cross-counterflow design were noted. Cycle modifications, enhanced heat transfer techniques and incorporation of advanced materials were suggested options to reduce system development risk. Carbon-carbon sheeting or foam proved an attractive option to improve overall performance.

Using conventional recuperator designs, the 0.95 effectiveness proved difficult to achieve without exceeding other performance targets; a metallic, plate-fin counterflow solution called for 15% more mass and 33% higher pressure-loss than the target values. Two types of gas-coolers showed promise. Single-pass counterflow and multipass cross-counterflow arrangements both met the 0.97 effectiveness requirement. Potential reliability-related advantages of the cross-countefflow design were noted. Cycle modifications, enhanced heat transfer techniques and incorporation of advanced materials were suggested options to reduce system development risk. Carbon-carbon sheeting or foam proved an attractive option to improve overall performance.

    The objective of this study was to examine the effect of caffeine on judo performance, perceived exertion, and plasma lactate response when ingested during recovery from a 5-day weight loss period. Six judokas performed two cycles of a 5-day rapid weight loss procedure to reduce their body weight by ~5%. After weigh-in, subjects re-fed and rehydrated over a 4-h recovery period. In the third hour of this "loading period", subjects ingested a capsule containing either caffeine (6 mg·kg-1) or placebo. One hour later, participants performed three bouts of a judo fitness test with 5-min recovery periods. Perceived exertion and plasma lactate were measured before and immediately after each test bout. Body weight was reduced in both caffeine and placebo conditions after the weight loss period (-3.9% ± 1.6% and -4.0% ± 2.3% from control, respectively, p < 0.05). At three hours after weigh-in, body weight had increased with both treatments but remained below the control (-3.0% ± 1.3% and -2.7% ± 2.2%). There were no significant differences in the number of throws between the control, caffeine or placebo groups. However, plasma lactate was systemically higher and perceived exertion lower in the subjects who ingested caffeine compared to either the control or placebo subjects (p < 0.05). In conclusion, caffeine did not improve performance during the judo fitness test after a 5-day weight loss period, but reduced perceived exertion and increased plasma lactate. PMID:25054553

    This study examines the role of teachers' expectations in the association between children's socio-economic background and achievement outcomes. Furthermore, the role of children's ethnicity in moderating this mediated relation is investigated. In the present study, 3,948 children from kindergarten are examined. Data are analysed by means of structural equation modeling. First, results show that teachers' expectations mediate the relation between children's SES and their later language and math achievement, after controlling for children's ethnicity, prior achievement and gender. This result indicates that teachers may exacerbate individual differences between children. Second, children's ethnicity moderates the mediation effect of teachers' expectations with respect to math outcomes. The role of teachers' expectations in mediating the relation between SES and math outcomes is stronger for majority children than for minority children. PMID:22506023

    Self-reflective performance review and expert evaluation are features of Western music performance practice. While music is usually the focus, visual information provided by performing musicians’ expressive bodily behaviors communicates expressiveness to musically trained and untrained observers. Yet, within a seemingly homogenous group, such as one of musically trained individuals, diversity of experience exists. Individual differences potentially affect perception of the subtleties of expressive performance, and performers’ effective communication of their expressive intentions. This study aimed to compare self- and other expert musicians’ perception of expressive bodily behaviors observed in marimba performance. We hypothesized that analyses of expressive bodily behaviors differ between expert musicians according to their specialist motor expertise and familiarity with the music. Two professional percussionists and experienced marimba players, and one professional classical singer took part in the study. Participants independently conducted Laban effort-shape analysis – proposing that intentions manifest in bodily activity are understood through shared embodied processes – of a marimbists’ expressive bodily behaviors in an audio-visual performance recording. For one percussionist, this was a self-reflective analysis. The work was unfamiliar to the other percussionist and singer. Perception of the performer’s expressive bodily behaviors appeared to differ according to participants’ individual instrumental or vocal motor expertise, and familiarity with the music. Furthermore, individual type of motor experience appeared to direct participants’ attention in approaching the analyses. Findings support forward and inverse perception–action models, and embodied cognitive theory. Implications offer scientific rigor and artistic interest for how performance practitioners can reflectively analyze performance to improve expressive communication. PMID:25400601

  9. Assessing performance enhancing tools: experiences with the open performance review and appraisal system (OPRAS) and expectations towards payment for performance (P4P) in the public health sector in Tanzania

    PubMed Central

    2012-01-01

    Background Health workers’ motivation is a key determinant of the quality of health services, and poor motivation has been found to be an obstacle to service delivery in many low-income countries. In order to increase the quality of service delivery in the public sector in Tanzania, the Open Performance Review and Appraisal System (OPRAS) has been implemented, and a new results-based payment system, Payment for performance (P4P) is introduced in the health sector. This article addresses health workers’ experiences with OPRAS, expectations towards P4P and how lessons learned from OPRAS can assist in the implementation of P4P. The broader aim is to generate knowledge on health workers’ motivation in low-income contexts. Methods A qualitative study design has been employed to elicit data on health worker motivation at a general level and in relation to OPRAS and P4P in particular. Focus group discussions (FGDs) and in-depth interviews (IDIs) have been conducted with nursing staff, clinicians and administrators in the public health sector in a rural district in Tanzania. The study has an ethnographic backdrop based on earlier long-term fieldwork in Tanzania. Results Health workers evaluated OPRAS and P4P in terms of the benefits experienced or expected from complying with the tools. The study found a general reluctance towards OPRAS as health workers did not see OPRAS as leading to financial gains nor did it provide feedback on performance. Great expectations were expressed towards P4P due to its prospects of topping up salaries, but the links between the two performance enhancing tools were unclear. Conclusions Health workers respond to performance enhancing tools based on whether the tools are found appropriate or yield any tangible benefits. The importance placed on salary and allowances forms the setting in which OPRAS operates. The expected addition to the salary through P4P has created a vigorous discourse among health workers attesting to the importance of the salary for motivation. Lessons learned from OPRAS can be utilized in the implementation of P4P and can enhance our knowledge on motivation and performance in the health services in low-income contexts such as Tanzania.

    Park, Y -J; Normani, S D; Sykes, J F; Sudicky, E A

    2011-01-01

    Cornaton et al. [2007] introduced the concept of lifetime expectancy as a performance measure of the safety of subsurface repositories, based upon the travel time for contaminants released at a certain point in the subsurface to reach the biosphere or compliance area. The methodologies are applied to a hypothetical but realistic Canadian Shield crystalline rock environment, which is considered to be one of the most geologically stable areas on Earth. In an approximately 10\\times10\\times1.5 km3 hypothetical study area, up to 1000 major and intermediate fracture zones are generated from surface lineament analyses and subsurface surveys. In the study area, mean and probability density of lifetime expectancy are analyzed with realistic geologic and hydrologic shield settings in order to demonstrate the applicability of the theory and the numerical model for optimally locating a deep subsurface repository for the safe storage of spent nuclear fuel. The results demonstrate that, in general, groundwater lifetime exp...

    The New Horizons (NH) payload includes a Radio Science Experiment (REX) for investigating key characteristics of Pluto and Charon during the upcoming flyby in July 2015. REX flight equipment augments the NH radio transceiver used for spacecraft communications and tracking. The REX hardware implementation requires 1.6 W and 160 g. This presentation will focus on the final design and the predicted performance of two high-priority observations. First, REX will receive signals from a pair of 70-m antennas on Earth - each transmitting 20 kW at 4.2-cm wavelength - during a diametric radio occultation by Pluto. The data recorded by REX will reveal the surface pressure, the temperature structure of the lower atmosphere, and the surface radius. Second, REX will measure the thermal emission from Pluto at 4.2-cm wavelength during two linear scans across the disk at close range when both the dayside and the nightside are visible, allowing the surface temperature and its spatial variations to be determined. Both scans extend from limb to limb with a resolution of about 10 pixels; one bisects Pluto whereas the second crosses the winter pole. We will illustrate the capabilities of REX by reviewing the method of analysis and the precision achieved in a lunar occultation observed by New Horizons in May 2011. Re-analysis of radio occultation measurements by Voyager 2 at Triton is also under way. More generally, REX objectives include a radio occultation search for Pluto's ionosphere; examination of Charon through both radio occultation and radiometry; a search for a radar echo from Pluto's surface; and improved knowledge of the Pluto system mass and the Pluto-Charon mass ratio from a combination of two-way and one-way Doppler frequency measurements.

    1994-12-01

    On October 18, 1991, the IEEE-USA produced an entity statement which endorsed the vital importance of the High Performance Computer and Communications Act of 1991 (HPCC) and called for the rapid implementation of all its elements. Efforts are now underway to develop a Computer Based Patient Record (CBPR), the National Information Infrastructure (NII) as part of the HPCC, and the so-called `Patient Card'. Multiple legislative initiatives which address these and related information technology issues are pending in Congress. Clearly, a national information system will greatly affect the way health care delivery is provided to the United States public. Timely and reliable information represents a critical element in any initiative to reform the health care system as well as to protect and improve the health of every person. Appropriately used, information technologies offer a vital means of improving the quality of patient care, increasing access to universal care and lowering overall costs within a national health care program. Health care reform legislation should reflect increased budgetary support and a legal mandate for the creation of a national health care information system by: (1) constructing a National Information Infrastructure; (2) building a Computer Based Patient Record System; (3) bringing the collective resources of our National Laboratories to bear in developing and implementing the NII and CBPR, as well as a security system with which to safeguard the privacy rights of patients and the physician-patient privilege; and (4) utilizing Government (e.g. DOD, DOE) capabilities (technology and human resources) to maximize resource utilization, create new jobs and accelerate technology transfer to address health care issues.

    2002-01-01

    On 15 October 1997 at 4:43 AM EDT, the Cassini spacecraft was successfully launched on a Titan IVB/Centaur on a mission to explore the Saturnian system. It carried three Radioisotope Thermoelectric Generators (RTGs) and 117 Light Weight Radioisotope Heater Units (LWRHUs). As part of the joint National Aeronautics and Space Administration (NASA)/U.S. Department of Energy (DoE) safety effort, a contingency plan was prepared to address the unlikely events of an accidental suborbital reentry or out-of-orbital reentry. The objective of the plan was to develop procedures to predict, within hours, the Earth impact footprints (EIFs) for the nuclear heat sources released during the atmospheric reentry. The footprint predictions would be used in subsequent notification and recovery efforts. As part of a multi-agency team, The Johns Hopkins University Applied Physics Laboratory (JHU/APL) had the responsibility to predict the EIFs of the heat sources after a reentry, given the heat sources' release conditions from the main spacecraft. (No ablation burn-through of the heat sources' aeroshells was expected, as a result of earlier testing.) JHU/APL's other role was to predict the time of reentry from a potential orbital decay. The tools used were a three degree-of-freedom trajectory code, a database of aerodynamic coefficients for the heat sources, secure links to obtain tracking data, and a high fidelity special perturbation orbit integrator code to predict time of spacecraft reentry from orbital decay. In the weeks and days prior to launch, all the codes and procedures were exercised. Notional EIFs were derived from hypothetical reentry conditions. EIFs predicted by JHU/APL were compared to those by JPL and US SPACECOM, and were found to be in good agreement. The reentry time from orbital decay for a booster rocket for the Russian Progress M-36 freighter, a cargo ship for the Mir space station, was predicted to within 5 minutes more than two hours before reentry. For the Cassini launch, JHU/APL's on-station real-time launch contingency activities were implemented. Live news from NASA Select TV of a successful Cassini launch and interplanetary injection precluded any further contingency actions. The Cassini launch contingency effort contributed to mission safety and demonstrated successful cooperation between several agencies. .

  1. Implicit fear and effort-related cardiac response.

    Chatelain, Mathieu; Gendolla, Guido H E

    2015-10-01

    Based on the Implicit-Affect-Primes-Effort (IAPE) model (Gendolla, 2012, 2015), two experiments tested the impact of fear primes on effort-related cardiac response. The main dependent variable was reactivity of cardiac pre-ejection period (PEP) during the performance of cognitive tasks. The IAPE model predicts that activation of implicit fear and sadness results in stronger PEP responses during task performance than activation of implicit happiness or anger. To test this, Experiment 1 exposed participants to masked facial expressions of fear, anger, or happiness while they performed a cognitive "parity task". As expected, PEP responses in the implicit fear condition were stronger than in both the implicit anger and happiness conditions. Experiment 2 conceptually replicated the implicit fear effect and revealed, as expected, stronger PEP responses for implicit fear and sadness than implicit anger during a "mental concentration" task. The findings provide the first evidence for the systematic impact of implicit fear on effort-related cardiac response and complete the existing evidence for the IAPE model. PMID:26325221

  2. Relief expectation and sleep.

    Laverdure-Dupont, Danièle; Rainville, Pierre; Montplaisir, Jacques; Lavigne, Gilles

    2010-01-01

    Originally, a role for sleep in learning and memory has been advocated following the observation of sleep-dependent performance enhancements at simple procedural tasks. With the investigation of a variety of cognitive and behavioral abilities, multiple stages of memory were further suggested to benefit from the off-line reprocessing believed to occur during specific sleep stages. In particular, REM sleep has been implicated in the integration of new information into associative networks as well as in the abstraction and generalization of implicit rules allowing adaptive behaviors. In a recent study, we extended these observations by demonstrating that the mediating effect of expectation on placebo-induced analgesia is strengthened by sleep, and that the individual amount of REM sleep is predictive of the relief expected on the next morning. However, this relation is strongly modulated by the level of concordance between expectations and sensory information available prior to sleep. As placebo responses derive from the learned association between contextual cues and subsequent relief, these results are discussed in relation to the proposed roles of REM sleep in the integrative stages of memory processing. In light of the responsiveness of REM sleep to waking events, its expression is also proposed to reflect the cognitive demand associated with the offline reprocessing of information necessary for the assimilation of new expectations to one's belief system.

    The Telemetry Agile Manufacturing Effort (TAME) is an agile enterprising demonstration sponsored by the US Department of Energy (DOE). The project experimented with new approaches to product realization and assessed their impacts on performance, cost, flow time, and agility. The purpose of the project was to design the electrical and mechanical features of an integrated telemetry processor, establish the manufacturing processes, and produce an initial production lot of two to six units. This paper outlines the major methodologies utilized by the TAME, describes the accomplishments that can be attributed to each methodology, and finally, examines the lessons learned and explores the opportunities for improvement associated with the overall effort. The areas for improvement are discussed relative to an ideal vision of the future for agile enterprises. By the end of the experiment, the TAME reduced production flow time by approximately 50% and life cycle cost by more than 30%. Product performance was improved compared with conventional DOE production approaches.

    Motivational theories of choice focus on the influence of goal values and strength of reinforcement to explain behavior. By contrast relatively little is known concerning how the cost of an action, such as effort expended, contributes to a decision to act. Effort-based decision making addresses how we make an action choice based on an integration of action and goal values. Here we review behavioral and neurobiological data regarding the representation of effort as action cost, and how this impacts on decision making. Although organisms expend effort to obtain a desired reward there is a striking sensitivity to the amount of effort required, such that the net preference for an action decreases as effort cost increases. We discuss the contribution of the neurotransmitter dopamine (DA) toward overcoming response costs and in enhancing an animal's motivation toward effortful actions. We also consider the contribution of brain structures, including the basal ganglia and anterior cingulate cortex, in the internal generation of action involving a translation of reward expectation into effortful action.

    The Transiting Exoplanet Survey Satellite (TESS) will launch in 2017 as a NASA Explorer mission, and will discover hundreds of new small planets transiting nearby, bright stars. As has been the case with Kepler, understanding and limiting systematic noise sources will be key to squeezing the best photometric precision out of the TESS instrument. I will describe our efforts at MIT to minimize such systematics, speaking both generally and in regard to one very specific challenge: mitigating the scourge of cosmic rays passing through TESS's thick CCD detectors. I will present the current data collection strategy and its expected performance in light of these known error sources, and I will share detailed simulations of what the TESS survey data will be like. Harnessing the unique opportunity offered by this focus meeting, I hope to solicit feedback from the ExoStats community on what additional lessons from Kepler should be considered in advance of the launch of TESS.

    2007-04-01

    A deep geologic repository for high level radioactive waste is under development by the U.S. Department of Energy at Yucca Mountain (YM), Nevada. As mandated in the Energy Policy Act of 1992, the U.S. Environmental Protection Agency (EPA) has promulgated public health and safety standards (i.e., 40 CFR Part 197) for the YM repository, and the U.S. Nuclear Regulatory Commission has promulgated licensing standards (i.e., 10 CFR Parts 2, 19, 20, etc.) consistent with 40 CFR Part 197 that the DOE must establish are met in order for the YM repository to be licensed for operation. Important requirements in 40 CFR Part 197 and 10 CFR Parts 2, 19, 20, etc. relate to the determination of expected (i.e., mean) dose to a reasonably maximally exposed individual (RMEI) and the incorporation of uncertainty into this determination. This presentation describes and illustrates how general and typically nonquantitive statements in 40 CFR Part 197 and 10 CFR Parts 2, 19, 20, etc. can be given a formal mathematical structure that facilitates both the calculation of expected dose to the RMEI and the appropriate separation in this calculation of aleatory uncertainty (i.e., randomness in the properties of future occurrences such as igneous and seismic events) and epistemic uncertainty (i.e., lack of knowledge about quantities that are poorly known but assumed to have constant values in the calculation of expected dose to the RMEI).

    Both the new high temperature superconductors (HTS) and the low temperature superconductors (LTS) are important components of Navy's total plan to integrate superconductivity into field operational systems. Fundamental research is an important component of the total Navy program and focuses on the HTS materials. Power applications (ship propulsion, etc.) use LTS materials while space applications (MMW electronics, etc.) use HTS materials. The Space Experiment being conducted at NRL will involve space flight testing of HTS devices built by industry and will demonstrate the ability to engineer and space qualify these devices for systems use. Another important component of the Navy's effort is the development of Superconducting Quantum Interference Device (SQUID) magnetometers. This program will use LTS materials initially, but plans to implement HTS materials as soon as possible. Hybrid HTS/LTS systems are probable in many applications. A review of the status of the Navy's HTS materials research is given as well as an update on the Navy's development efforts in superconductivity, with particular emphasis on the related SDIO sponsored program on HTS applications.

Pre- and posttrial questionnaires were administered to assess producer attitudes. We found that the monthly analysis reports were used in the management of the dairy farms and were found to be a useful management tool. The majority of producers indicated a willingness to pay, on average, $6.86/cow/year for such a service. PMID:17423946

    After the introduction of a law prohibiting the start-up of any new nuclear power plant until the utility had shown that the waste produced by the plant could be taken care of in an absolutely safe way, the Swedish nuclear utilities in December 1976 embarked on the Nuclear Fuel Safety Project, which in November 1977 presented a first report, Handling of Spent Nuclear Fuel and Final Storage of Vitrified Waste (KBS-I), and in November 1978 a second report, Handling and Final Storage of Unreprocessed Spent Nuclear Fuel (KBS II). These summary reports were supported by 120 technical reports prepared by 450 experts. The project engaged 70 private and governmental institutions at a total cost of US $15 million. The KBS-I and KBS-II reports are summarized in this document, as are also continued waste research efforts carried out by KBS, SKBF, PRAV, ASEA and other Swedish organizations. The KBS reports describe all steps (except reprocessing) in handling chain from removal from a reactor of spent fuel elements until their radioactive waste products are finally disposed of, in canisters, in an underground granite depository. The KBS concept relies on engineered multibarrier systems in combination with final storage in thoroughly investigated stable geologic formations. This report also briefly describes other activities carried out by the nuclear industry, namely, the construction of a central storage facility for spent fuel elements (to be in operation by 1985), a repository for reactor waste (to be in operation by 1988), and an intermediate storage facility for vitrified high-level waste (to be in operation by 1990). The R and D activities are updated to September 1981.

  14. When is irony effortful?

    Spotorno, Nicola; Noveck, Ira A

    2014-08-01

    Whereas some studies indicate that ironic-as opposed to literal-readings of utterances take longer to process, others indicate that the 2 are processed at comparable speeds. We propose that mindreading processes are at least partly responsible for the mixed results, as we present 3 experiments that include stories having a target utterance with either an Ironic or Literal reading. Experiment 1 replicates earlier findings (Spotorno, Koun, Prado, Van Der Henst, & Noveck, 2012) showing that ironic readings take longer than literal ones when fillers include decoys, stories that call for an ironic remark but present a banal utterance instead and thus diffuse participants' expectations for irony. Starting with Experiment 2, decoys are removed, leading to effects that are arguably revealing of Theory of Mind processes. One is an Early-Late effect, which occurs when ironic utterances are read as readily as literal ones in the 2nd half of an experimental session, creating "mixed" results in the laboratory. In Experiment 3, we further added antecedents before a critical event so that, later, the target utterance would be echoing an explicitly stated thought and would facilitate irony comprehension (Gibbs, 1986; Sperber & Wilson, 1981). Results reveal an Early-Late effect here, too. Further evidence of Theory of Mind activity follows from analyses of participants' Social Skill subscale scores in the Autism-Spectrum Quotient (Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001). Socially inclined participants are more likely than the socially disinclined to use a story's negative event to portend the arrival of an irony; in contrast, socially disinclined participants appear more reactive than the socially inclined to explicit antecedents.

    NASA developed the Earth Observing System (EOS) during the 1990'S. At the Land Processes Distributed Active Archive Center (LP DAAC), located at the USGS EROS Data Center, the EOS Data and Information System (EOSDIS) is required to support heritage missions as well as Landsat 7, Terra, and Aqua. The original system concept of the early 1990'S changed as each community had its say - first the managers, then engineers, scientists, developers, operators, and then finally the general public. The systems at the LP DAAC - particularly the largest single system, the EOSDIS Core System (ECS) - are changing as experience accumulates, technology changes, and each user group gains influence. The LP DAAC has adapted as contingencies were planned for, requirements and therefore plans were modified, and expectations changed faster than requirements could hope to be satisfied. Although not responsible for Quality Assurance of the science data, the LP DAAC works to ensure the data are accessible and useable by influencing systems, capabilities, and data formats where possible, and providing tools and user support as necessary. While supporting multiple missions and instruments, the LP DAAC also works with and learns from multiple management and oversight groups as they review mission requirements, system capabilities, and the overall operation of the LP DAAC. Stakeholders, including the Land Science community, are consulted regularly to ensure that the LP DAAC remains cognizant and responsive to the evolving needs of the user community. Today, the systems do not look or function as originally planned, but they do work, and they allow customers to search and order of an impressive amount of diverse data.

    de Morree, Helma M; Marcora, Samuele M

    2010-12-01

    It is a common observation that exertion of effort is associated with a specific facial expression. However, this facial expression has never been quantified during physical tasks and its relationship with effort is unknown. The aims of the present study were to measure frowning muscle activity during a physical task with electromyography (EMG) and to investigate the relationship between facial EMG and effort. Effort was experimentally manipulated by increasing task difficulty and inducing muscle weakness. Twenty men performed leg extensions with four relative workloads. The fatigue group (n=10) repeated the leg extensions after fatiguing eccentric exercise, and the control group repeated just the leg extensions. Facial EMG amplitude, ratings of perceived effort (RPE), and leg EMG amplitude increased significantly with increasing task difficulty and with muscle fatigue. Facial EMG, RPE, and leg EMG all correlated significantly. The results suggest that frowning muscle activity reflects effort during physical tasks. PMID:20832447

  3. Cognitive effort: A neuroeconomic approach.

    PubMed

    Westbrook, Andrew; Braver, Todd S

    2015-06-01

    Cognitive effort has been implicated in numerous theories regarding normal and aberrant behavior and the physiological response to engagement with demanding tasks. Yet, despite broad interest, no unifying, operational definition of cognitive effort itself has been proposed. Here, we argue that the most intuitive and epistemologically valuable treatment is in terms of effort-based decision-making, and advocate a neuroeconomics-focused research strategy. We first outline psychological and neuroscientific theories of cognitive effort. Then we describe the benefits of a neuroeconomic research strategy, highlighting how it affords greater inferential traction than do traditional markers of cognitive effort, including self-reports and physiologic markers of autonomic arousal. Finally, we sketch a future series of studies that can leverage the full potential of the neuroeconomic approach toward understanding the cognitive and neural mechanisms that give rise to phenomenal, subjective cognitive effort.

    The GLAST Burst Monitor (GBM) will enhance LAT observations of GRBs by extending the spectral coverage from the LAT threshold down to {approx}8 keV, and will provide a trigger for re-orienting the spacecraft to observe delayed emission from selected bursts outside the LAT field of view. GBM consists of twelve NaI scintillation detectors operating in the 8 keV to 1 MeV energy range and two BGO scintillation detectors operating in the 150 keV to 30 MeV energy range. Detector resolution, effective area, and angular response have been determined by calibrations. Analyses indicate that the on-board burst threshold will be {approx}0.7 photons cm{sup -2}s{sup -1} and the on-board burst localization accuracy will typically be better than 8 deg.

  8. Prior expectations facilitate metacognition for perceptual decision.

    PubMed

    Sherman, M T; Seth, A K; Barrett, A B; Kanai, R

    2015-09-01

    The influential framework of 'predictive processing' suggests that prior probabilistic expectations influence, or even constitute, perceptual contents. This notion is evidenced by the facilitation of low-level perceptual processing by expectations. However, whether expectations can facilitate high-level components of perception remains unclear. We addressed this question by considering the influence of expectations on perceptual metacognition. To isolate the effects of expectation from those of attention we used a novel factorial design: expectation was manipulated by changing the probability that a Gabor target would be presented; attention was manipulated by instructing participants to perform or ignore a concurrent visual search task. We found that, independently of attention, metacognition improved when yes/no responses were congruent with expectations of target presence/absence. Results were modeled under a novel Bayesian signal detection theoretic framework which integrates bottom-up signal propagation with top-down influences, to provide a unified description of the mechanisms underlying perceptual decision and metacognition.

  9. An investigation of gender and grade-level differences in middle school students' attitudes about science, in science process skills ability, and in parental expectations of their children's science performance

    White, Terri Renee'

    The primary purpose of the study was to examine different variables (i.e. science process skill ability, science attitudes, and parents' levels of expectation for their children in science, which may impinge on science education differently for males and females in grades five, seven, and nine. The research question addressed by the study was: What are the differences between science process skill ability, science attitudes, and parents' levels of expectation in science on the academic success of fifth, seventh, and ninth graders in science and do effects differ according to gender and grade level? The subjects included fifth, seven, and ninth grade students ( n = 543) and their parents (n = 474) from six rural, public elementary schools and two rural, public middle schools in Southern Mississippi. A two-way (grade x gender) multivariate analysis of variance (MANOVA) was used to determine the differences in science process skill abilities of females and males in grade five, seven, and nine. An additional separate two-way multivariate analysis of variance (grade x gender) was also used to determine the differences in science attitudes of males and females in grade five, seven, and nine. A separate analysis of variance (PPSEX [parent's gender]) with the effects being parents' gender was used to determine differences in parents' levels of expectation for their childrens' performance in science. An additional separate analysis of variance (SSEX [student's gender]) with the effects being the gender of the student was also used to determine differences in parents' levels of expectation for their childrens' performance in science. Results of the analyses indicated significant main effects for grade level (p < .001) and gender (p < .001) on the TIPS II. There was no significant grade by gender interaction on the TIPS II. Results for the TOSRA also indicated a significant main effect for grade (p < .001) and the interaction of grade by sex ( p < .001). On variable ATT 5 (enjoyment of science lessons), males' attitudes toward science decreased across the grade levels; whereas, females decreased from grade five to seven, but showed a significant increase from grade seven to nine. Results from the analysis of variance with the parent's gender as the main effect showed no significant difference. The analysis of variance with student's gender as the main effect showed no significant difference.

    The design complexity of a software system may be characterized within a refinement level (e.g., data flow among modules), or between refinement levels (e.g., traceability between the specification and the design). We analyzed an existing set of data from NASA's Software Engineering Laboratory to test whether changing software modules with high design complexity requires more personnel effort than changing modules with low design complexity. By analyzing variables singly, we identified strong correlations between software design complexity and change effort for error corrections performed during the maintenance phase. By analyzing variables in combination, we found patterns which identify modules in which error corrections were costly to perform during the acceptance test phase.

    There are numerous problems with the hypothesis that brain dopamine (DA) systems, particularly in the nucleus accumbens, directly mediate the rewarding or primary motivational characteristics of natural stimuli such as food. Research and theory related to the functions of mesolimbic DA are undergoing a substantial conceptual restructuring, with the traditional emphasis on hedonia and primary reward yielding to other concepts and lines of inquiry. The present review is focused upon the involvement of nucleus accumbens DA in behavioral activation and effort-related processes. Viewed from the framework of behavioral economics, the effects of accumbens DA depletions and antagonism on food-reinforced behavior are highly dependent upon the work requirements of the instrumental task, and DA depleted rats are more sensitive to increases in response costs (i.e., ratio requirements). Moreover, interference with accumbens DA transmission exerts a powerful influence over effort-related choice behavior. Rats with accumbens DA depletions or antagonism reallocate their instrumental behavior away from food-reinforced tasks that have high response requirements, and instead these rats select a less-effortful type of food-seeking behavior. Nucleus accumbens DA and adenosine interact in the regulation of effort-related functions, and other brain structures (anterior cingulate cortex, amygdala, ventral pallidum) also are involved. Studies of the brain systems regulating effort-based processes may have implications for understanding drug abuse, as well as energy-related disorders such as psychomotor slowing, fatigue or anergia in depression and other neurological disorders.

    1993-01-01

    Aerospace is the leading positive contributor to this country's balance of trade, derived largely from the sale of U.S. commercial aircraft around the world. This powerfully favorable economic situation is being threatened in two ways: (1) the U.S. portion of the commercial transport market is decreasing, even though the worldwide market is projected to increase substantially; and (2) expenditures are decreasing for military aircraft, which often serve as proving grounds for advanced aircraft technology. To retain a major share of the world market for commercial aircraft and continue to provide military aircraft with unsurpassed performance, the U.S. aerospace industry faces many technological challenges. The field of applied aerodynamics is necessarily a major contributor to efforts aimed at meeting these technological challenges. A number of emerging research results that will provide new opportunities for applied aerodynamicists are discussed. Some of these have great potential for maintaining the high value of contributions from applied aerodynamics in the relatively near future. Over time, however, the value of these contributions will diminish greatly unless substantial investments continue to be made in basic and applied research efforts. The focus: to increase understanding of fluid dynamic phenomena, identify new aerodynamic concepts, and provide validated advanced technology for future aircraft.

    Many people with schizophrenia exhibit avolition, a difficulty initiating and maintaining goal-directed behavior, considered to be a key negative symptom of the disorder. Recent evidence indicates that patients with higher levels of negative symptoms differ from healthy controls in showing an exaggerated cost of the physical effort needed to obtain a potential reward. We examined whether patients show an exaggerated avoidance of cognitive effort, using the demand selection task developed by Kool, McGuire, Rosen, and Botvinick (Journal of Experimental Psychology. General, 139, 665-682, 2010). A total of 83 people with schizophrenia or schizoaffective disorder and 71 healthy volunteers participated in three experiments where instructions varied. In the standard task (Experiment 1), neither controls nor patients showed expected cognitive demand avoidance. With enhanced instructions (Experiment 2), controls demonstrated greater demand avoidance than patients. In Experiment 3, patients showed nonsignificant reductions in demand avoidance, relative to controls. In a control experiment, patients showed significantly reduced ability to detect the effort demands associated with different response alternatives. In both groups, the ability to detect effort demands was associated with increased effort avoidance. In both groups, increased cognitive effort avoidance was associated with higher IQ and general neuropsychological ability. No significant correlations between demand avoidance and negative symptom severity were observed. Thus, it appears that individual differences in general intellectual ability and effort detection are related to cognitive effort avoidance and likely account for the subtle reduction in effort avoidance observed in schizophrenia.

    2015-01-01

    Social scientists have drawn attention to the role of hype and optimistic visions of the future in providing momentum to biomedical innovation projects by encouraging innovation alliances. In this article, we show how less optimistic, uncertain, and modest visions of the future can also provide innovation projects with momentum. Scholars have highlighted the need for clinicians to carefully manage the expectations of their prospective patients. Using the example of a pioneering clinical team providing deep brain stimulation to children and young people with movement disorders, we show how clinicians confront this requirement by drawing on their professional knowledge and clinical expertise to construct visions of the future with their prospective patients; visions which are personalized, modest, and tainted with uncertainty. We refer to this vision-constructing work as recalibration, and we argue that recalibration enables clinicians to manage the tension between the highly optimistic and hyped visions of the future that surround novel biomedical interventions, and the exigencies of delivering those interventions in a clinical setting. Drawing on work from science and technology studies, we suggest that recalibration enrolls patients in an innovation alliance by creating a shared understanding of how the “effectiveness” of an innovation shall be judged.

  5. Expectations and speech intelligibility.

    PubMed

    Babel, Molly; Russell, Jamie

    2015-05-01

    Socio-indexical cues and paralinguistic information are often beneficial to speech processing as this information assists listeners in parsing the speech stream. Associations that particular populations speak in a certain speech style can, however, make it such that socio-indexical cues have a cost. In this study, native speakers of Canadian English who identify as Chinese Canadian and White Canadian read sentences that were presented to listeners in noise. Half of the sentences were presented with a visual-prime in the form of a photo of the speaker and half were presented in control trials with fixation crosses. Sentences produced by Chinese Canadians showed an intelligibility cost in the face-prime condition, whereas sentences produced by White Canadians did not. In an accentedness rating task, listeners rated White Canadians as less accented in the face-prime trials, but Chinese Canadians showed no such change in perceived accentedness. These results suggest a misalignment between an expected and an observed speech signal for the face-prime trials, which indicates that social information about a speaker can trigger linguistic associations that come with processing benefits and costs.

Given limitations on conservation spending, managers must choose from strategies that range from managing just one subpopulation and risking all other subpopulations to managing all subpopulations equally and poorly, thereby risking the loss of all subpopulations. We took an economic approach to this problem in an effort to discover a simple rule of thumb for optimally allocating conservation effort among subpopulations. This rule was derived by maximizing the expected number of extant subpopulations remaining given n subpopulations are actually managed. We also derived a spatiotemporally optimized strategy through stochastic dynamic programming. The rule of thumb suggested that more subpopulations should be managed if the budget increases or if the cost of reducing local extinction probabilities decreases. The rule performed well against the exact optimal strategy that was the result of the stochastic dynamic program and much better than other simple strategies (e.g., always manage one extant subpopulation or half of the remaining subpopulation). We applied our approach to the allocation of funds in 2 contrasting case studies: reduction of poaching of Sumatran tigers (Panthera tigris sumatrae) and habitat acquisition for San Joaquin kit foxes (Vulpes macrotis mutica). For our estimated annual budget for Sumatran tiger management, the mean time to extinction was about 32 years. For our estimated annual management budget for kit foxes in the San Joaquin Valley, the mean time to extinction was approximately 24 years. Our framework allows managers to deal with the important question of how to allocate scarce conservation resources among subpopulations of any threatened species. PMID:18477029

  12. Analysis Efforts Supporting NSTX Upgrades

    The National Spherical Torus Experiment (NSTX) is a low aspect ratio, spherical torus (ST) configuration device which is located at Princeton Plasma Physics Laboratory (PPPL) This device is presently being updated to enhance its physics by doubling the TF field to 1 Tesla and increasing the plasma current to 2 Mega-amperes. The upgrades include a replacement of the centerstack and addition of a second neutral beam. The upgrade analyses have two missions. The first is to support design of new components, principally the centerstack, the second is to qualify existing NSTX components for higher loads, which will increase by a factor of four. Cost efficiency was a design goal for new equipment qualification, and reanalysis of the existing components. Showing that older components can sustain the increased loads has been a challenging effort in which designs had to be developed that would limit loading on weaker components, and would minimize the extent of modifications needed. Two areas representing this effort have been chosen to describe in more details: analysis of the current distribution in the new TF inner legs, and, second, analysis of the out-of-plane support of the existing TF outer legs.

    The DarkLight (Detecting A Resonance Kinematically with eLectrons Incident on a Gaseous Hydrogen Target) experiment at Jefferson Lab intends to study the process e- p -->e- pA' , with A' being a hidden gauge boson decaying to e-e+ . DarkLight will explore the A' mass region 10-100 MeV with sensitivity to couplings as low as ?' /?EM ~10-7 with 1 ab-1 of data. The complete kinematic information provided by the DarkLight detector also permits a search for an invisibly decaying A'. In contrast to the numerous visible decay searches, both attempted and planned, there is considerably less data for the invisible decay. Furthermore, the limited data for invisibles' searches is from beam-dump and indirect decays, making this a unique measurement. This talk will focus on the invisibles effort for DarkLight, covering both the related physics and necessary instrumentation. DOE DE-SC0003884.

  2. Canadian efforts to prevent and control hypertension.

    2010-01-01

    Suboptimum blood pressure is estimated to be the leading risk factor for death worldwide and is associated with 13.5% of deaths globally. The clinical diagnosis of hypertension affects one in four adults globally and is expected to increase by 60% between 2000 and 2025. Clearly, global efforts to prevent and control hypertension are important health issues. While Canada had a prevalence of hypertension similar to that of the United States in the early 1990 s, the treatment and control rate was only 13% compared with 25% in the United States. A national strategic plan was developed, and a coalition of organizations and health care professional and scientist volunteers actively implemented parts of the strategy. Specific initiatives that have evolved include the development of hypertension knowledge translation programs for health professionals, the public and people with hypertension, an outcomes research program to assess the impact of hypertension and guide national-, regional- and community-based knowledge translation interventions, and a program to reduce the prevalence of hypertension by decreasing sodium additives in food. These initiatives have relied on the active involvement of health care professional volunteers, health care professional and scientific organizations and various government departments. There have been large increases in the diagnosis and treatment of hypertension, with corresponding reductions in cardiovascular disease and total mortality associated with the start of the hypertension initiatives. As a result, Canada is becoming recognized as a world leader in the prevention, treatment and control of hypertension. PMID:20847986

  3. Control of robotic assistance using poststroke residual voluntary effort.

    Poststroke hemiparesis limits the ability to reach, in part due to involuntary muscle co-activation (synergies). Robotic approaches are being developed for both therapeutic benefit and continuous assistance during activities of daily living. Robotic assistance may enable participants to exert less effort, thereby reducing expression of the abnormal co-activation patterns, which could allow participants to reach further. This study evaluated how well participants could perform a reaching task with robotic assistance that was either provided independent of effort in the vertical direction or in the sagittal plane in proportion to voluntary effort estimated from electromyograms (EMG) on the affected side. Participants who could not reach targets without assistance were enabled to reach further with assistance. Constant anti-gravity force assistance that was independent of voluntary effort did not reduce the quality of reach and enabled participants to exert less effort while maintaining different target locations. Force assistance that was proportional to voluntary effort on the affected side enabled participants to exert less effort and could be controlled to successfully reach targets, but participants had increased difficulty maintaining a stable position. These results suggest that residual effort on the affected side can produce an effective command signal for poststroke assistive devices. PMID:25373107

  4. Rain Hampers Tsunami Relief Efforts

    NASA Technical Reports Server (NTRS)

    2005-01-01

    The cleanup and relief efforts from the recent tsunamis continue in coastal communities that were ravaged by the waves all across the Indian Ocean. Heavy rains have further complicated the matter and added to the misery in parts of eastern Sri Lanka. Between December 28, 2004, and January 5, 2005, up to 10 to 15 inches of rain may have fallen along the southeast coast of the island, and as much as 20 inches (red areas) fell just offshore. This rainfall map was created by the TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center, which monitors rainfall over the global tropics. The map shows that many other regions around the Indian Ocean were also affected by the rains, including Malaysia and parts of Sumatra. The heaviest rains fell on December 31 and January 4. The rains were likely the result of a combination of the northeast monsoon interacting with the topography and an active phase of what is known as the Madden-Julian Oscillation (MJO) (or 30-60 day oscillation). The MJO is a large-scale disturbance that propagates eastward from the Indian Ocean into the West Pacific Ocean, bringing extended periods of unsettled weather with it. Individual convective complexes within the MJO can last on the order of a day. TRMM is a joint mission between NASA and the Japanese space agency JAXA.

  10. The expected value of control: An integrative theory of anterior cingulate cortex function

    PubMed Central

    Shenhav, Amitai; Botvinick, Matthew M.; Cohen, Jonathan D.

    2013-01-01

    Summary The dorsal anterior cingulate cortex (dACC) has a near-ubiquitous presence in the neuroscience of cognitive control. It has been implicated in a diversity of functions, from reward processing and performance monitoring to the execution of control and action selection. Here, we propose that this diversity can be understood in terms of a single underlying function: allocation of control based on an evaluation of the expected value of control (EVC). We present a normative model of EVC that integrates three critical factors: the expected payoff from a controlled process, the amount of control that must be invested to achieve that payoff, and the cost in terms of cognitive effort. We propose that dACC integrates this information, using it to determine whether, where and how much control to allocate. We then consider how the EVC model can explain the diverse array of findings concerning dACC function. PMID:23889930

    Engle-Friedman, Mindy

    2014-12-01

    Sleep loss appears to affect the capacity for performance and access to energetic resources. This paper reviews research examining the physical substrates referred to as resource capacity, the role of sleep in protecting that capacity and the reaction of the system as it attempts to respond with effort to overcome the limitations on capacity caused by sleep loss. Effort is the extent to which an organism will exert itself beyond basic levels of functioning or attempt alternative strategies to maintain performance. The purpose of this review is to bring together research across sleep disciplines to clarify the substrates that constitute and influence capacity for performance, consider how the loss of sleep influences access to those resources, examine cortical, physiological, perceptual, behavioral and subjective effort responses and consider how these responses reflect a system reacting to changes in the resource environment. When sleep deprived, the ability to perform tasks that require additional energy is impaired and the ability of the system to overcome the deficiencies caused by sleep loss is limited. Taking on tasks that require effort including school work, meal preparation, pulling off the road to nap when driving drowsy appear to be more challenging during sleep loss. Sleep loss impacts the effort-related choices we make and those choices may influence our health and safety. PMID:26483932

    1987-01-01

    The validity of the spectral analysis of sinus arrhythmia as a measure of mental effort was investigated using a computer simulation of a hovercraft piloted along a river as the experimental task. Strong correlation was observed between the subjective effort-ratings and the heart-rate variability (HRV) power spectrum between 0.06 and 0.14 Hz. Significant correlations were observed not only between subjects but, more importantly, within subjects as well, indicating that the spectral analysis of HRV is an accurate measure of the amount of effort being invested by a subject. Results also indicate that the intensity of effort invested by subjects cannot be inferred from the objective ratings of task difficulty or from performance.

    Under the sponsorship of the Office of Naval Research, The Naval Surface Warfare Center (NSWC) is the focal point for exploratory battery development within the US Navy. NSWC is responsible for identifying naval power needs not met by existing technology. To accomplish this, the authors conduct a biennial power source survey to assess the technology gap between state-of-the-art battery performance and mid-to-long term fleet needs. Once Navy power requirements have been identified, high payoff technologies are developed to meet them. During the 1993 survey, the authors identified four Navy systems requiring battery developments, namely sonobuoys, mines, underwater vehicles and torpedoes. Power supply inadequacies were found to be the result of two important factors, a shift in Navy focus from deep ocean waters to the more complex, littoral (coastal) environments, and an increased emphasis on the cost effectiveness of a system in an era of reduced military budgets. The survey revealed the following issues: (1) future sonobuoys will require significantly greater power than the presently used lithium/sulfur dioxide batteries can provide; (2) there is concern in the mine community over the future availability of specific batteries; (3) in the case of underwater vehicles (including torpedo targets), there is a desire for a more cost-effective power source having a greater energy density than the presently used silver oxide/zinc cells; (4) enhanced energy density was requested by the torpedo community to provide increased operational time. As expected, safety and environmental issues were of concern to participants responding to the survey. This paper will discuss the recommendations of the power needs survey and summarize efforts underway to implement them.

    The importance of evaluating effort in neuropsychological assessments has been widely acknowledged, but measuring effort in the context of dementia remains challenging due to the impact of dementia severity on effort measure scores. Two embedded measures have been developed for the repeatable battery for the assessment of neuropsychological status (RBANS; Randolph, C., Tierney, M. C., Mohr, E., & Chase, T. N. (1998). The repeatable battery for the assessment of neuropsychological status (RBANS): Preliminary clinical validity. Journal of Clinical and Experimental Neuropsychology, 20 (3), 310-319): the Effort Index (EI; Silverberg, N. D., Wertheimer, J. C., & Fichtenberg, N. L. (2007). An effort index for the repeatable battery for the assessment of neuropsychological status (RBANS). Clinical Neuropsychologist, 21 (5), 841-854) and the Effort Scale (ES; Novitski, J., Steele, S., Karantzoulis, S., & Randolph, C. (2012). The repeatable battery for the assessment of neuropsychological status effort scale. Archives of Clinical Neuropsychology, 27 (2), 190-195). We explored failure rates on these effort measures in a non-litigating mixed dementia sample (N = 145). Failure rate on the EI was high (48%) and associated with dementia severity. In contrast, failure on the ES was 14% but differed based on type of dementia. ES failure was low (4%) when dementia was due to Alzheimer disease (AD), but high (31%) for non-AD dementias. These data raise concerns about use of the RBANS embedded effort measures in dementia evaluations. PMID:25472686

    2014-01-01

    This study investigates the channel coordination issue of a supply chain with a risk-neutral manufacturer and a loss-averse retailer facing stochastic demand that is sensitive to sales effort. Under the loss-averse newsvendor setting, a distribution-free gain/loss-sharing-and-buyback (GLB) contract has been shown to be able to coordinate the supply chain. However, we find that a GLB contract remains ineffective in managing the supply chain when retailer sales efforts influence the demand. To effectively coordinate the channel, we propose to combine a GLB contract with sales rebate and penalty (SRP) contract. In addition, we discover a special class of gain/loss contracts that can coordinate the supply chain and arbitrarily allocate the expected supply chain profit between the manufacturer and the retailer. We then analyze the effect of loss aversion on the retailer's decision-making behavior and supply chain performance. Finally, we perform a numerical study to illustrate the findings and gain additional insights. PMID:25197696

    2014-01-01

    Functional imaging studies frequently report that the hippocampus is engaged by successful episodic memory retrieval. However, considering that concurrent encoding of the background environment occurs during retrieval and influences medial temporal lobe activity, it is plausible that hippocampal encoding functions are reduced with increased attentional engagement during effortful retrieval. Expanding upon evidence that retrieval efforts suppress activity in hippocampal regions implicated in encoding, this study examines the influence of retrieval effort on encoding performance and the interactive effects of encoding and retrieval on hippocampal and neocortical activity. Functional magnetic resonance imaging was conducted while subjects performed a word recognition task with incidental picture encoding. Both lower memory strength and increased search duration were associated with encoding failure and reduced hippocampal and default network activity. Activity in the anterior hippocampus tracked encoding, which was more strongly deactivated when incidental encoding was unsuccessful. These findings highlight potential contributions from background encoding processes to hippocampal activations during neuroimaging studies of episodic memory retrieval. PMID:23378272

    2014-01-01

    Background Laryngeal allotransplantation (LA) is a technique involving transplantation of a deceased donor's larynx into a recipient, and it may be substituted for conventional laryngeal reconstruction. There are widely different views on LA, as the recipient is administered continuous, potentially life-threatening, immunosuppressive therapy for a functional or aesthetic result, which is not directly related to life extension. The purpose of this study was to analyze the difference in risk acceptance and expectations of LA between four population groups. Methods A survey was performed to examine patients' risk acceptance and expectations of LA. The survey included 287 subjects in total (general public, n=100; kidney transplant recipients, n=53; post-laryngectomy patients, n=34; doctors, n=100), using a Korean translated version of the louisville instrument for transplantation (LIFT) questionnaire. Results All four groups responded differently at various levels of their perception in risk acceptance and expectations. The kidney transplant recipients reported the highest risk acceptance and expectations, and the doctor group the lowest. Conclusions This study examined the disparate perception between specific population groups of the risks and benefits of using LA for the promotion of the quality of life. By addressing the information gaps about LA in the different populations that have been highlighted from this survey, we suggest that LA can become a more viable alternative to classical surgery with resultant improved quality of life for patients.

  9. Software Faults Fixing Effort: Analysis and Prediction

    2014-01-01

    Software developers spend significant amount of their time fixing faults. However, not many papers have addressed the effort needed to fix software faults. This paper is focused on comprehensive analysis of the fix implementation effort and factors that affect it, as well as on predicting the level of effort based on information recorded in software change requests. The work is based on data related to 1200 failures, extracted from the change tracking system of a large NASA mission. Our results show that (1) 83% of the total fix implementation effort was associated with only 20% of failures. (2) Both safety critical failures and post-release failures required three times more effort to fix compared to non-critical and pre-release counterparts, respectively. (3) Failures with fixes spread across multiple components and/or across multiple types of software artifacts required more effort. The spread across artifacts was more costly than spread across components. (4) Surprisingly, some types of faults associated with later life-cycle did not require significant effort, especially if only one type of artifact was fixed. (5) The level of fix implementation effort was predicted with 73% accuracy. The medium level fix implementation effort was classified more successfully than both low and high levels.

  14. Efforts to emulate human milk oligosaccharides.

    Espinosa, Rosa María; Taméz, Martha; Prieto, Pedro

    2007-10-01

    Research on human milk oligosaccharides (HMO) began with the characterisation of their chemical structures and is now focused on the elucidation of their biological roles. Previously, biological effects could only be investigated with fractions or structures isolated from breast milk; consequently, clinical observations were limited to comparisons between outcomes from breast-fed infants and their formula-fed counterparts. In some cases, it was inferred that the observed differences were caused by the presence of HMO in breast milk. Presently, analytical techniques allow for the fast analysis of milk samples, thus providing insights on the inherent variability of specimens. In addition, methods for the synthesis of HMO have provided single structures in sufficient quantities to perform clinical studies with oligosaccharide-supplemented formulae. Furthermore, studies have been conducted with non-mammalian oligosaccharides with the purpose of assessing the suitability of these structures to functionally emulate HMO. Taken together, these developments justify summarising current knowledge on HMO to further discussions on efforts to emulate human milk in regard to its oligosaccharide content. The present account summarises published data and intends to provide an historical context and to illustrate the state of the field. PMID:17922965

    2013-12-01

    The lack of initiative, drive or effort in patients with schizophrenia is linked to marked functional impairments. However, our assessment of effort and motivation is crude, relying on clinical rating scales based largely on patient recall. In order to better understand the neurobiology of effort in schizophrenia, we need more rigorous measurements of this construct. In the behavioural neuroscience literature, decades of work has been carried out developing various paradigms to examine the neural underpinnings of an animal's willingness to expend effort for a reward. Here, we shall review this literature on the nature of paradigms used in rodents to assess effort, as well as those used in humans. Next, the neurobiology of these effort-based decisions will be discussed. We shall then review what is known about effort in schizophrenia, and what might be inferred from experiments done in other human populations. Lastly, we shall discuss future directions of research that may assist in shedding light on the neurobiology of effort cost computations in schizophrenia. PMID:24035741

    2015-09-01

    Low IQ has recently been shown to predict neuropsychological effort test failure in healthy and neurological populations. Although low IQ is common in schizophrenia (SZ), its effect on effort test performance remains unclear in this population. The current study examined the role of IQ in effort test performance in a sample of 60 outpatients with SZ and 30 demographically matched healthy controls (CN). Participants were administered a battery of neuropsychological tests, and insufficient effort was calculated using two embedded effort indices: the Reliable Digit Span Effort Index and the Finger Tapping Effort Index. Results indicated that 16.1% of SZ patients and 0% CN failed both effort measures and that 32.1% of SZ and 3.3% of CN failed one measure. In SZ, IQ in the <70 or 70-79 range was associated with the highest rates of falling below the effort cut-off scores; however, patients with IQs in the low-average or higher range (>80) did not fall below effort cut-offs. Findings suggest that low IQ is a significant predictor of insufficient effort during neuropsychological test performance in schizophrenia, calling into question the validity of neuropsychological effort testing in SZ patients with low IQ.

  5. The Martyrdom Effect: When Pain and Effort Increase Prosocial Contributions

    PubMed Central

    Olivola, Christopher Y; Shafir, Eldar

    2013-01-01

    Most theories of motivation and behavior (and lay intuitions alike) consider pain and effort to be deterrents. In contrast to this widely held view, we provide evidence that the prospect of enduring pain and exerting effort for a prosocial cause can promote contributions to the cause. Specifically, we show that willingness to contribute to a charitable or collective cause increases when the contribution process is expected to be painful and effortful rather than easy and enjoyable. Across five experiments, we document this “martyrdom effect,” show that the observed patterns defy standard economic and psychological accounts, and identify a mediator and moderator of the effect. Experiment 1 showed that people are willing to donate more to charity when they anticipate having to suffer to raise money. Experiment 2 extended these findings to a non-charity laboratory context that involved real money and actual pain. Experiment 3 demonstrated that the martyrdom effect is not the result of an attribute substitution strategy (whereby people use the amount of pain and effort involved in fundraising to determine donation worthiness). Experiment 4 showed that perceptions of meaningfulness partially mediate the martyrdom effect. Finally, Experiment 5 demonstrated that the nature of the prosocial cause moderates the martyrdom effect: the effect is strongest for causes associated with human suffering. We propose that anticipated pain and effort lead people to ascribe greater meaning to their contributions and to the experience of contributing, thereby motivating higher prosocial contributions. We conclude by considering some implications of this puzzling phenomenon. Copyright © 2011 John Wiley & Sons, Ltd. PMID:23559692

  6. Not all effort is equal: the role of the anterior cingulate cortex in different forms of effort-reward decisions

    2014-01-01

    The rat anterior cingulate cortex (ACC) mediates effort-based decision making when the task requires the physical effort of climbing a ramp. Normal rats will readily climb a barrier leading to high reward whereas rats with ACC lesions will opt instead for an easily obtained small reward. The present study explored whether the role of ACC in cost-benefit decisions extends beyond climbing by testing its role in ramp climbing as well as two novel cost-benefit decision tasks, one involving the physical effort of lifting weights and the other the emotional cost of overcoming fear (i.e., “courage”). As expected, rats with extensive ACC lesions tested on a ramp-climbing task were less likely to choose a high-reward/high-effort arm than sham controls. However, during the first few trials, lesioned rats were as likely as controls to initially turn into the high-reward arm (HRA) but far less likely to actually climb the barrier, suggesting that the role of the ACC is not in deciding which course of action to pursue, but rather in maintaining a course of action in the face of countervailing forces. In the effort-reward decision task involving weight lifting, some lesion animals behaved like controls while others avoided the HRA. However, the results were not statistically significant and a follow-up study using incremental increasing effort failed to show any difference between lesion and control groups. The results suggest that the ACC is not needed for effort-reward decisions involving weight lifting but may affect motor abilities. Finally, a courage task explored the willingness of rats to overcome the fear of crossing an open, exposed arm to obtain a high reward. Both sham and ACC-lesioned animals exhibited equal tendencies to enter the open arm. However, whereas sham animals gradually improved on the task, ACC-lesioned rats did not. Taken together, the results suggest that the role of the ACC in effort-reward decisions may be limited to certain tasks. PMID:24478659

  8. Reproductive effort and success of wild female mallards: does male quality matter?

    In accordance with the differential allocation hypothesis, females are expected to increase their reproductive investment when mated to high-quality males. In waterfowl, reproductive, investment increased when captive female mallards (Anas platyrhynchos) were mated to more attractive males, but information for wild ducks is lacking. Studies of waterfowl mating systems have focused primarily on the importance of plumage coloration of males and female mate choice, whereas investigations of reproductive ecology examine female attributes and virtually ignore the role of males in investment decisions. Here, we used unique data for 253 pairs of wild mallards to test whether females mated to high-quality males would increase reproductive effort and reproduce more successfully. We derived measurements of female and male body size and condition, and indices of male plumage quality, and related these traits to patterns of reproductive effort and performance of females. Consistent with predictions, yearling females nested earlier and had higher nest survival when mated to males with better plumage scores. Furthermore, when paired with larger bodied males, yearling females renested more often, and nest and brood survival increased among older females. Although the strength of male effects varied with breeding stage and female age or experience, this is one of a few studies to demonstrate an additive effect of male quality on investment and success of females, in free-ranging birds.

    The study had two primary objectives. The first was to determine whether sleep loss results in a preference for tasks demanding minimal effort. The second was to evaluate the quality of performance when participants, under conditions of sleep loss, have control over task demands. In experiment 1, using a repeated-measures design, 50 undergraduate college students were evaluated, following one night of no sleep loss and one night of sleep loss. The Math Effort Task (MET) presented addition problems via computer. Participants were able to select additions at one of five levels of difficulty. Less-demanding problems were selected and more additions were solved correctly when the participants were subject to sleep loss. In experiment 2, 58 undergraduate college students were randomly assigned to a no sleep deprivation or a sleep deprivation condition. Sleep-deprived participants selected less-demanding problems on the MET. Percentage correct on the MET was equivalent for both the non-sleep-deprived and sleep-deprived groups. On a task selection question, the sleep-deprived participants also selected significantly less-demanding non-academic tasks. Increased sleepiness, fatigue, and reaction time were associated with the selection of less difficult tasks. Both groups of participants reported equivalent effort expenditures; sleep-deprived participants did not perceive a reduction in effort. These studies demonstrate that sleep loss results in the choice of low-effort behavior that helps maintain accurate responding. PMID:12753348

    Humans possess a developmentally precocious and evolutionarily ancient approximate number system (ANS) whose sensitivity correlates with uniquely human symbolic arithmetic skills. Recent studies suggest that ANS training improves symbolic arithmetic, but such studies may engender performance expectations in their participants that in turn produce the improvement. Here, we assessed 6- to 8-year-old children's expectations about the effects of numerical and non-numerical magnitude training, as well as states of satiety and restfulness, in the context of a study linking children's ANS practice to their improved symbolic arithmetic. We found that children did not expect gains in symbolic arithmetic after exercising the ANS, although they did expect gains in ANS acuity after training on any magnitude task. Moreover, children expected gains in symbolic arithmetic after a good night's sleep and their favourite breakfast. Thus, children's improved symbolic arithmetic after ANS training cannot be explained by their expectations about that training. PMID:26399713

    2014-01-01

    Two studies examined how effort invested in a task shapes the affective predictions related to potential success in that task, and the mechanism underlying this relationship. In Study 1, PhD students awaiting an editorial decision about a submitted manuscript estimated the effort they had invested in preparing that manuscript for submission and how happy they would feel if it were accepted. Subjective estimates of effort were positively related to participants' anticipated happiness, an effect mediated by the higher perceived quality of one's work. In other words, the more effort one though having invested, the happier one expected to feel if it were accepted, because one expected a higher quality manuscript. We replicated this effect and its underlying mediation in Study 2, this time using an experimental manipulation of effort in the context of creating an advertising slogan. Study 2 further showed that participants mistakenly thought their extra efforts invested in the task had improved the quality of their work, while independent judges had found no objective differences in quality between the outcomes of the high- and low-effort groups. We discuss the implications of the relationship between effort and anticipated emotions and the conditions under which such relationship might be functional. PMID:25028961

  17. Malaria epidemic expected in Mozambique.

    2000-03-11

    Health experts fear epidemics of several infectious diseases in Mozambique as floods recede and mosquitoes begin breeding. According to Pierre Kahozi of WHO, malaria is already endemic in the region but there are fears that a much greater outbreak might occur. Scores of suspected cases of cholera were reported and more are expected, along with cases of other diarrheal conditions. Neil Cameron, chief director of communicable diseases at the health department in South Africa, said that more cases are expected within a month when the breeding cycle of mosquitoes is renewed. He reported that the number of malaria cases in South Africa increased from 12,000 in 1995 to 50,000 in 1999, and a number of people had been dying from this disease. The increase could be attributed partly to climatic changes and resistance to certain drugs. DDT had been used in the past to control mosquitoes, and it¿s possible that it will be used again in Mozambique. The issues involved in tackling malaria are now being considered as part of a special development initiative on infectious diseases that is being undertaken jointly by the health departments of three countries: South Africa, Mozambique, and Swaziland.

    2007-01-01

    This research aimed to test the relative value of developing and using job-specific facets of effort and testing them using J. Siegrist's (1996) effort-reward imbalance (ERI) theory to extend understanding of how one might determine job strain in urban bus driving. In addition, the interactive effects of the ERI model are further investigated to address the lack of research into the relationships of the model's constructs. Using focus groups and published papers, a measure of bus driver effort was created, which was subsequently completed by 186 male U.K. bus drivers as part of a questionnaire study. The results were factor analyzed to create 4 facets of effort, which demonstrated additional variance in predicting strain, above and beyond J. Siegrist's original effort construct. One facet, workload and fatigue, was observed to be a particularly important contributor to strain. The analyses further indicated that the ERI model's assumptions that ERI creates job strain could not be completely upheld, although poorer levels of reward and higher levels of overcommitment were strong main predictors of job strain. Research and applied implications are considered. PMID:17257066

    Summary Background To plan for pensions and health and social services, future mortality and life expectancy need to be forecast. Consistent forecasts for all subnational units within a country are very rare. Our aim was to forecast mortality and life expectancy for England and Wales' districts. Methods We developed Bayesian spatiotemporal models for forecasting of age-specific mortality and life expectancy at a local, small-area level. The models included components that accounted for mortality in relation to age, birth cohort, time, and space. We used geocoded mortality and population data between 1981 and 2012 from the Office for National Statistics together with the model with the smallest error to forecast age-specific death rates and life expectancy to 2030 for 375 of England and Wales' 376 districts. We measured model performance by withholding recent data and comparing forecasts with this withheld data. Findings Life expectancy at birth in England and Wales was 79·5 years (95% credible interval 79·5–79·6) for men and 83·3 years (83·3–83·4) for women in 2012. District life expectancies ranged between 75·2 years (74·9–75·6) and 83·4 years (82·1–84·8) for men and between 80·2 years (79·8–80·5) and 87·3 years (86·0–88·8) for women. Between 1981 and 2012, life expectancy increased by 8·2 years for men and 6·0 years for women, closing the female–male gap from 6·0 to 3·8 years. National life expectancy in 2030 is expected to reach 85·7 (84·2–87·4) years for men and 87·6 (86·7–88·9) years for women, further reducing the female advantage to 1·9 years. Life expectancy will reach or surpass 81·4 years for men and reach or surpass 84·5 years for women in every district by 2030. Longevity inequality across districts, measured as the difference between the 1st and 99th percentiles of district life expectancies, has risen since 1981, and is forecast to rise steadily to 8·3 years (6·8–9·7) for men and 8·3 years (7·1–9·4) for women by 2030. Interpretation Present forecasts underestimate the expected rise in life expectancy, especially for men, and hence the need to provide improved health and social services and pensions for elderly people in England and Wales. Health and social policies are needed to curb widening life expectancy inequalities, help deprived districts catch up in longevity gains, and avoid a so-called grand divergence in health and longevity.

  20. Contrasting responses of male and female foraging effort to year-round wind conditions.

    There is growing interest in the effects of wind on wild animals, given evidence that wind speeds are increasing and becoming more variable in some regions, particularly at temperate latitudes. Wind may alter movement patterns or foraging ability, with consequences for energy budgets and, ultimately, demographic rates. These effects are expected to vary among individuals due to intrinsic factors such as sex, age or feeding proficiency. Furthermore, this variation is predicted to become more marked as wind conditions deteriorate, which may have profound consequences for population dynamics as the climate changes. However, the interaction between wind and intrinsic effects has not been comprehensively tested. In many species, in particular those showing sexual size dimorphism, males and females vary in foraging performance. Here, we undertook year-round deployments of data loggers to test for interactions between sex and wind speed and direction on foraging effort in adult European shags Phalacrocorax aristotelis, a pursuit-diving seabird in which males are c. 18% heavier. We found that foraging time was lower at high wind speeds but higher during easterly (onshore) winds. Furthermore, there was an interaction between sex and wind conditions on foraging effort, such that females foraged for longer than males when winds were of greater strength (9% difference at high wind speeds vs. 1% at low wind speeds) and when winds were easterly compared with westerly (7% and 4% difference, respectively). The results supported our prediction that sex-specific differences in foraging effort would become more marked as wind conditions worsen. Since foraging time is linked to demographic rates in this species, our findings are likely to have important consequences for population dynamics by amplifying sex-specific differences in survival rates.

    2008-01-01

    Summary Objective To provide an overview of the expansion in public access to electronic biomedical information over the past two decades, with an emphasis on developments to which the U.S. National Library of Medicine contributed. Methods Review of the increasingly broad spectrum of web-accessible genomic data, biomedical literature, consumer health information, clinical trials data, and images. Results The amount of publicly available electronic biomedical information has increased dramatically over the past twenty years. Rising expectations regarding access to biomedical information were stimulated by the spread of the Internet, the World Wide Web, advanced searching and linking techniques. These informatics advances simplified and improved access to electronic information and reduced costs, which enabled inter-organizational collaborations to build and maintain large international information resources and also aided outreach and education efforts The demonstrated benefits of free access to electronic biomedical information encouraged the development of public policies that further increase the amount of information available.

    As the mechanisms of the associations between substance use and risky sex remain unclear, this study investigates the interactive roles of conflicts about casual sex and condom use and expectancies of the sexual effects of substances in those associations among gay men. Conflict interacted with expectancies to predict sexual behavior under the influence; low casual sex conflict coupled with high expectancies predicted the highest number of casual partners, and high condom use conflict and high expectancies predicted the highest number of unprotected sex acts. Results have implications for intervention efforts that aim to improve sexual decision-making and reduce sexual expectancies. PMID:23584507

  4. Anticipated effort in imagined self-rotation.

    Chronometric studies provide strong support that mental imagery recruits perceptual processes [Shepard and Cooper, 1982 Mental Images and Their Transformations (Cambridge, MA: MIT Press)]. Recent studies suggest that anticipated effort influences perception (Proffitt et al, 2003 Psychological Science 14 106-112). If anticipated effort influences perception and perception supports imagery, then anticipated effort may influence imagery. To examine the role of effort in mental imagery, participants in experiment 1 imagined self-rotation across two conditions of distance. Simulated rotation took 156 ms longer in larger settings, even though the amount of imagined angular rotation was the same in both settings. This finding suggests the start-to-goal arc is incorporated when imagining rotation through a given angle. Experiment 2 replicated the distance effect (232 ms) and added a variable for load. Simulated rotation took 167 ms longer with imaginary heavy loads. The results suggest that both spatial metrics and anticipated effort may play a role in the coding of mental imagery. PMID:19323138

  8. Seismic Modeling on a GPU with Modest Programming Effort

    2012-12-01

    We demonstrate an effective approach to porting a production code of anelastic wave propagation using a directive-based programming model, called Mint. Mint generated code realized about 80% of the performance of hand-coded CUDA on the Nvidia 200 and 400 series of GPUs. We think this performance gap is reasonable in light of the simplified programming model enjoyed by Mint's pragma-based model. Compared with writing CUDA by hand, Mint provides the flexibility to explore different performance variants of the same program through annotations and compiler options which saves considerable amount of programming effort. In this talk, we discuss how Mint enables the programmer to tune performance at a high level and evaluate various performance programming strategies realized by Mint programs and translator optimization options.

    2003-02-01

    This article presents the proceedings of a symposium at the 2002 RSA Meeting in San Francisco, organized by Reinout W. Wiers and Mark D. Wood. The symposium combined two topics of recent interest in studies of alcohol expectancies: cognitive mechanisms in expectancy challenge studies, and context-related changes of expectancies. With increasing recognition of the substantial role played by alcohol expectancies in drinking, investigators have begun to develop and evaluate expectancy challenge procedures as a potentially promising new prevention strategy. The two major issues addressed in the symposium were whether expectancy challenges result in changes in expectancies that mediate intervention (outcome relations), and the influence of simulated bar environments ("bar labs," in which challenges are usually done) on expectancies. The presentations were (1) An introduction, by Jack Darkes; (2) Investigating the utility of alcohol expectancy challenge with heavy drinking college students, by Mark D. Wood; (3) Effects of an expectancy challenge on implicit and explicit expectancies and drinking, by Reinout W. Wiers; (4) Effects of graphic feedback and simulated bar assessments on alcohol expectancies and consumption, by William R. Corbin; (5) Implicit alcohol associations and context, by Barry T Jones; and (6) A discussion by Kenneth J. Sher, who pointed out that it is important not only to study changes of expectancies in the paradigm of an expectancy challenge but also to consider the role of changing expectancies in natural development and in treatments not explicitly aimed at changing expectancies.

    1995-01-01

    Early basic research showed that increases in required response effort (or force) produced effects that resembled those produced by punishment. A recent study by Alling and Poling determined some subtle differences between the two behavior-change strategies, but also confirmed that increasing required effort is an effective response-reduction procedure with enduring effects. In this paper we summarize basic research on response effort and explore the role of effort in diverse applied areas including deceleration of aberrant behavior, attention deficit hyperactivity disorder, oral habits, health care appointment keeping, littering, indexes of functional disability, and problem solving. We conclude that renewed interest in response effort as an independent variable is justified because of its potent effects and because the political constraints imposed on punishment- and reinforcement-based procedures have yet to be imposed on procedures that entail manipulations of response effort.

    Decisions soon will be made which will set in motion the development of Qatar's huge North Dome gas field. The government and state company, Qatar General Petroleum Corp. (QGPC) is studying the results of 2 feasibility studies on the economics of LNG export, although initially North Dome exploitation will be aimed at the domestic market. Decisions on the nature and timing of the North Dome development are the most important that have had to be faced in the short 10-yr history of the small Gulf state. The country's oil production is currently running at approximately 500,000 bpd, with 270,000 bpd originating from 3 offshore fields. Output is expected to decline through 1990, and it generally is accepted that there is little likelihood of further major crude discoveries. Therefore, Qatar has to begin an adjustment from an economy based on oil to one based on gas, while adhering to the underlying tenets of long-term conservation and industrial diversification.

  15. Establishing Realistic Patient Expectations Following Total Knee Arthroplasty.

    PubMed

    Husain, Adeel; Lee, Gwo-Chin

    2015-12-01

    Nearly 20% of patients are dissatisfied following well-performed total knee arthroplasty with good functional outcomes. Surgeons must understand the drivers of dissatisfaction to minimize the number of unhappy patients following surgery. Several studies have shown that unfulfilled expectations are a principal source of patient dissatisfaction. Patients contemplating total knee arthroplasty expect pain relief, improved walking ability, return to sports, and improvement in psychological well-being and social interactions. However, patients are typically overly optimistic with regard to expected outcomes following surgery. Patient expectations and satisfaction can be influenced by age, socioeconomic factors, sex, and race. The interplay of these factors can be complex and specific to each person. Published data on clinical and functional outcomes show that persistence of symptoms, such as pain, stiffness, and failure to return to preoperative levels of function, are common and normal. Therefore, the surgeon needs to help the patient to establish realistic expectations. PMID:26493969

  16. Mapping Fishing Effort through AIS Data

    2015-01-01

    Several research initiatives have been undertaken to map fishing effort at high spatial resolution using the Vessel Monitoring System (VMS). An alternative to the VMS is represented by the Automatic Identification System (AIS), which in the EU became compulsory in May 2014 for all fishing vessels of length above 15 meters. The aim of this paper is to assess the uptake of the AIS in the EU fishing fleet and the feasibility of producing a map of fishing effort with high spatial and temporal resolution at European scale. After analysing a large AIS dataset for the period January-August 2014 and covering most of the EU waters, we show that AIS was adopted by around 75% of EU fishing vessels above 15 meters of length. Using the Swedish fleet as a case study, we developed a method to identify fishing activity based on the analysis of individual vessels’ speed profiles and produce a high resolution map of fishing effort based on AIS data. The method was validated using detailed logbook data and proved to be sufficiently accurate and computationally efficient to identify fishing grounds and effort in the case of trawlers, which represent the largest portion of the EU fishing fleet above 15 meters of length. Issues still to be addressed before extending the exercise to the entire EU fleet are the assessment of coverage levels of the AIS data for all EU waters and the identification of fishing activity in the case of vessels other than trawlers.

    The Galileo Teacher Training Program (GTTP) successfully named representatives in nearly 100 nations in 2009, the International Year of Astronomy (IYA2009). The challenge had just begun. The steps ahead are how to reach educators that might benefit from our program and how to help build a more fair and science literate society, a society in which good tools and resources for science education are not the privilege of a few. From 2010 on our efforts have been to strengthen the newly formed network and learn how to equally help educators and students around the globe. New partnerships with other strong programs and institutions are being formed, sponsorship schemes being outlined, new tools and resources being publicized, and on-site and video conference training conducted all over the world. Efforts to officially accredit a GTTP curriculum are on the march and a stronger certification process being outlined. New science topics are being integrated in our effort and we now seek to discuss the path ahead with experts in this field and the community of users, opening the network to all corners of our beautiful blue dot. The main aim of this article is to open the discussion regarding the urgent issue of how to reawaken student interest in science, how to solve the gender inequality in science careers, and how to reach the underprivileged students and open to them the same possibilities. Efforts are in strengthening the newly formed network and learning how to equally help educators and students around the globe.

  6. Expected geoneutrino signal at JUNO

    2015-12-01

    Constraints on the Earth's composition and on its radiogenic energy budget come from the detection of geoneutrinos. The Kamioka Liquid scintillator Antineutrino Detector (KamLAND) and Borexino experiments recently reported the geoneutrino flux, which reflects the amount and distribution of U and Th inside the Earth. The Jiangmen Underground Neutrino Observatory (JUNO) neutrino experiment, designed as a 20 kton liquid scintillator detector, will be built in an underground laboratory in South China about 53 km from the Yangjiang and Taishan nuclear power plants, each one having a planned thermal power of approximately 18 GW. Given the large detector mass and the intense reactor antineutrino flux, JUNO aims not only to collect high statistics antineutrino signals from reactors but also to address the challenge of discriminating the geoneutrino signal from the reactor background. The predicted geoneutrino signal at JUNO is terrestrial neutrino unit (TNU), based on the existing reference Earth model, with the dominant source of uncertainty coming from the modeling of the compositional variability in the local upper crust that surrounds (out to approximately 500 km) the detector. A special focus is dedicated to the 6° × 4° local crust surrounding the detector which is estimated to contribute for the 44% of the signal. On the basis of a worldwide reference model for reactor antineutrinos, the ratio between reactor antineutrino and geoneutrino signals in the geoneutrino energy window is estimated to be 0.7 considering reactors operating in year 2013 and reaches a value of 8.9 by adding the contribution of the future nuclear power plants. In order to extract useful information about the mantle's composition, a refinement of the abundance and distribution of U and Th in the local crust is required, with particular attention to the geochemical characterization of the accessible upper crust where 47% of the expected geoneutrino signal originates and this region contributes the major source of uncertainty.

  8. Expected results of Cassini Radio Science experiments

    NASA Astrophysics Data System (ADS)

    Castillo, J.; Rappaport, N.

    Cassini gravity radio science experiments scheduled from February 2005 to July 2008 are expected to improve our knowledge of the Saturnian system through direct measurements of gravity parameters performed in a multidisciplinary and comparative planetary science approach. In 2005, direct mass determination will be achieved for Enceladus, Hyperion, and Dione, as well as gravity field measurement of Rhea. Detection of an ocean suspected to lie within Titan is expected to happen by 2007. However, after the two first flybys scheduled in 2006, the determination of the dimensionless moment of inertia of this body will provide scientists with enough information to build detailed models to be compared with the Galilean satellites. Density determination of all major satellites will be performed through navigation passes scheduled throughout the tour. Accurate and independent determination of Saturn's high zonal harmonics up to degree 8 will provide crucial constraints on the interior of this giant planet by the end of the initial mission. Comparison of direct mass determination with values inferred from analytical theories is very important. Besides, density distribution sampling in the Saturnian system will provide new constraints on the models of evolution of Saturn's subnebula, as well as references for compared planetology with the Jovian satellites. This is particularly timely as a mission toward Jupiter is being scheduled in the frame of NASA New Frontiers program. Fresh geophysical observations of icy satellites and the finding or absence of a deep ocean within Titan will be crucial inputs for constraining numerical models of internal and external dynamics of this category of bodies. We will especially stress out the synergy between the information provided by the Radio Science Subsystems with the other instruments onboard Cassini to leverage our understanding of the phenomena responsible for the dynamics and evolution of the icy satellites.

    2010-06-01

    This study was designed to evaluate the association between BMI and classroom effort in third to fifth grade, ages seven through 12. Teachers, completely blinded and unaware of the study at the time of their classroom evaluations, provided reports of academic performance and effort. Boys and girls (n = 45), which are members of an ethnically diverse community, participated. In addition to classroom measures, height, weight, and percentage body fat were evaluated. A multiple regression model controlling for ethnicity, gender, and age revealed that increasing BMI scores had little association with academic performance but effort scores decreased significantly as BMI increased. This is the first study to show that elevations in BMI in children are associated with decreasing effort in an academic setting. Thus, BMI associated reductions in effort may result in suboptimal levels of performance in the academic setting as well as in other aspects of life. PMID:20388720

    The performance of Model Reference Adaptive Control (MRAC) is studied in numerical simulations with the objective of understanding the effects of differences between the plant and the reference model. MRAC is applied to two structural systems with adjustable error between the reference model and the actual plant. Performance indices relating to control effort and response characteristics are monitored in order to determine what effects small errors have on the control effort and performance of the two systems. It is shown that reasonable amounts of error in the reference model can cause dramatic increases in both the control effort and response magnitude (as measured by energy integrals) of the plant.

    2007-11-01

    Multiple scales reflecting student effort were developed using factor and scale analysis on data from an introductory physics course. This data included interactions with an on-line homework system. One of the scales displays many characteristics of a metric of the individual level of engagement in the course. This scale is shown to be a good predictor of performance on class exams and the Force Concept Inventory (FCI). Furthermore, normalized learning gains on the FCI are well predicted by this scale while pre-instructional FCI scores provide no additional predictive ability, agreeing with observations by Richard Hake. This scale also correlates strongly with epistemological beliefs that learning is related to effort and is the responsibility of the student. The factors that enter into this scale, writing and mastering expert-like problem-solving, are consistent with this being a measure of individual levels of class engagement.

    The NCAR effort is primarily focused on the analysis of a diverse suite of measurements taken at the southern end of the Salt Lake City Valley within the Jordan Narrows. These measurements include wind profiler, surface, lidar, radiosonde, multi-layered tether-sonde and sodar measurements. We are also collaborating with other VTMX investigators through linking our measurements within the Jordan Narrows with their investigations. The instrumentation was provided to interested VTMX investigators and was used extensively. Thus the NCAR data set played a large role in the results of the overall experiment. Our work under this proposal includes analysis of the observations, mesoscale modeling efforts in support of our VTMX analysis and general instrumentation development aimed at improving the measurement of vertical transport and mixing under stable conditions.

    Experimental efforts to develop a new procedure to measure char depth in carbon phenolic nozzle material are described. Using a Shor Type D Durometer, hardness profiles were mapped across post fired sample blocks and specimens from a fired rocket nozzle. Linear regression was used to estimate the char depth. Results are compared to those obtained from computed tomography in a comparative experiment. There was no significant difference in the depth estimates obtained by the two methods.

    Research in motivation and emotion has been increasingly influenced by the perspective that processes underpinning the motivated approach of rewarding goals are distinct from those underpinning enjoyment during reward consummation. This distinction recently inspired the construction of the Temporal Experience of Pleasure Scale (TEPS), a self-report measure that distinguishes trait anticipatory pleasure (pre-reward feelings of desire) from consummatory pleasure (feelings of enjoyment and gratification upon reward attainment). In a university community sample (N = 97), we examined the TEPS subscales as predictors of (1) the willingness to expend effort for monetary rewards, and (2) affective responses to a pleasant mood induction procedure. Results showed that both anticipatory pleasure and a well-known trait measure of reward motivation predicted effort-expenditure for rewards when the probability of being rewarded was relatively low. Against expectations, consummatory pleasure was unrelated to induced pleasant affect. Taken together, our findings provide support for the validity of the TEPS anticipatory pleasure scale, but not the consummatory pleasure scale. PMID:26115223

  7. Effects of resolving to change one's own behavior: expectations vs. experience.

    The "false-hope syndrome" suggests that unrealistic expectations are responsible for the cycle of repeated failure and renewed efforts at self-change characterizing many self-changers. Our hypotheses were that: (1) committing to a particular self-change task would inflate initial expectations, (2) participants would be unsuccessful relative to their expectations, and (3) more elevated expectations would lead to more negative outcomes. Participants were randomly assigned to either increase their physical activity or reduce their stress through meditating or were assigned to a no-change control group. In accordance with Hypotheses 1 and 2, exercise participants had more positive expectations about their resolutions immediately after committing to them, and both exercise and meditation participants were unsuccessful relative to their expectations. With respect to Hypothesis 3, however, having more positive expectations about one's resolution did not predict a worse outcome. PMID:19433147

  9. When is Deceptive Message Production More Effortful than Truth-Telling? A Baker’s Dozen of Moderators

    PubMed Central

    Burgoon, Judee K.

    2015-01-01

    Deception is thought to be more effortful than telling the truth. Empirical evidence from many quarters supports this general proposition. However, there are many factors that qualify and even reverse this pattern. Guided by a communication perspective, I present a baker’s dozen of moderators that may alter the degree of cognitive difficulty associated with producing deceptive messages. Among sender-related factors are memory processes, motivation, incentives, and consequences. Lying increases activation of a network of brain regions related to executive memory, suppression of unwanted behaviors, and task switching that is not observed with truth-telling. High motivation coupled with strong incentives or the risk of adverse consequences also prompts more cognitive exertion–for truth-tellers and deceivers alike–to appear credible, with associated effects on performance and message production effort, depending on the magnitude of effort, communicator skill, and experience. Factors related to message and communication context include discourse genre, type of prevarication, expected response length, communication medium, preparation, and recency of target event/issue. These factors can attenuate the degree of cognitive taxation on senders so that truth-telling and deceiving are similarly effortful. Factors related to the interpersonal relationship among interlocutors include whether sender and receiver are cooperative or adversarial and how well-acquainted they are with one another. A final consideration is whether the unit of analysis is the utterance, turn at talk, episode, entire interaction, or series of interactions. Taking these factors into account should produce a more nuanced answer to the question of when deception is more difficult than truth-telling.

    Recent years have witnessed a dynamic development of mammary gland imaging techniques, particularly ultrasonography and magnetic resonance imaging. A challenge related to these studies is the increase in the precision of the anatomical assessment of breast, particularly for early detection of subclinical lesions, performance of ultrasound- guided biopsy procedures, and accurate preoperative location of pathological lesions so as to optimize the surgical treatment. Ultrasound imaging is a primary and baseline diagnostic procedure the patient with suspected pathological lesions within breast is referred to by the surgeon. Lesions visualized in ultrasound scans are classified according to the BI-RADS US assessment categories. The successive categories (2 through 6) encompass individual pathological lesions, estimating the risk of malignancy and provide guidelines for further diagnostic and therapeutic management. This article described the important aspects of ultrasonographic imaging of focal lesions within the breasts as significant from the standpoint of surgical treatment of patients falling within BI-RADS US categories 3, 4, 5, and 6. Attention is drawn to the importance of ultrasound scans in the assessment of axillary fossa lymph nodes before the decision regarding the surgical treatment.

    This study aimed to examine the effects of arousal and expectation on eyewitness memory. We exposed 97 participants to an immersive eyewitness experience by creating four virtual reality stimulus environments. The participants were randomly assigned to one of four conditions: arousing and expected, arousing and unexpected, nonarousing and expected, and nonarousing and unexpected. The results revealed that memory performance for an arousing encounter was significantly lower than that for a nonarousing encounter, and that memory performance for an unexpected environment was significantly lower compared with an expected one. In addition, memory performance was lowest in the condition that was both arousing and unexpected. No interaction between arousal and expectation was found. PMID:25405783

    A conceptual framework was developed for assessing the sub-level of protection in 185 multiple-use marine protected areas (MPAs) in the English Channel through a survey on management effort. Data were retrieved from 153 MPAs: 4.56% were assigned low management effort, 83.70% were assigned medium management effort, and 11.76% were assigned high management effort. Overall, French MPAs performed better in terms of management effort than English MPAs and lack of consistency in ratings by different management bodies in England was found. Lack of correlation between management effort and conservation status within an available subset of 13 MPAs suggests that management may not be as influential a factor for the effective conservation of MPAs, especially in marine environments under heavy human pressure such as the English Channel. It is suggested that MPAs in such areas may therefore require an upgrade of their legal level of protection to be effective. PMID:25825075

  16. Cumulative assessment: strategic choices to influence students’ study effort

    2013-01-01

    Background It has been asserted that assessment can and should be used to drive students’ learning. In the current study, we present a cumulative assessment program in which test planning, repeated testing and compensation are combined in order to influence study effort. The program is aimed at helping initially low-scoring students improve their performance during a module, without impairing initially high-scoring students’ performance. We used performance as a proxy for study effort and investigated whether the program worked as intended. Methods We analysed students’ test scores in two second-year (n?=?494 and n?=?436) and two third-year modules (n?=?383 and n?=?345) in which cumulative assessment was applied. We used t-tests to compare the change in test scores of initially low-scoring students with that of initially high-scoring students between the first and second subtest and again between the combined first and second subtest and the third subtest. During the interpretation of the outcomes we took regression to the mean and test difficulty into account. Results Between the first and the second subtest in all four modules, the scores of initially low-scoring students increased more than the scores of initially high-scoring students decreased. Between subtests two and three, we found a similar effect in one module, no significant effect in two modules and the opposite effect in another module. Conclusion The results between the first two subtests suggest that cumulative assessment may positively influence students’ study effort. The inconsistent outcomes between subtests two and three may be caused by differences in perceived imminence, impact and workload between the third subtest and the first two. Cumulative assessment may serve as an example of how several evidence-based assessment principles can be integrated into a program for the benefit of student learning. PMID:24370117

    Stimulus expectation can modulate neural responses in early sensory cortical regions, with expected stimuli often leading to a reduced neural response. However, it is unclear whether this expectation suppression is an automatic phenomenon or is instead dependent on the type of task a subject is engaged in. To investigate this, human subjects were presented with visual grating stimuli in the periphery that were either predictable or non-predictable while they performed three tasks that differently engaged cognitive resources. In two of the tasks, the predictable stimulus was task-irrelevant and spatial attention was engaged at fixation, with a high load on either perceptual or working memory resources. In the third task, the predictable stimulus was task-relevant, and therefore spatially attended. We observed that expectation suppression is dependent on the cognitive resources engaged by a subjects’ current task. When the grating was task-irrelevant, expectation suppression for predictable items was visible in retinotopically specific areas of early visual cortex (V1-V3) during the perceptual task, but it was abolished when working memory was loaded. When the grating was task-relevant and spatially attended, there was no significant effect of expectation in early visual cortex. These results suggest that expectation suppression is not an automatic phenomenon, but dependent on attentional state and type of available cognitive resources. PMID:26098331

  18. Impact of health savings accounts on precautionary savings, demand for health insurance and prevention effort.

    Steinorth, Petra

    2011-03-01

    The paper examines the influence of health savings accounts (HSAs) on optimal savings, insurance demand and prevention effort over the course of a lifetime. This paper adds to the literature by investigating HSAs as both a form of insurance and as saving vehicle in an expected utility framework. Assuming no regulatory constraints on the deductible, we show that individuals voluntarily choose a positive deductible and increase their savings with HSAs. If the government-imposed minimum deductible becomes too great, however, individuals may instead choose to remain in traditional insurance. We determine the effect of HSAs on prevention effort. We find that an increased tax subsidy may worsen moral hazard issues. Assuming partial risk aversion to be less than or equal to one, individuals will either invest less in the health preservation effort and more money in the HSA or vice versa. However, they will never increase both effort and savings simultaneously as was intended when HSAs were introduced. PMID:21349595

    Human respiratory effort can be harvested to power wearable biosensors and mobile electronic devices. The very first step toward designing a harvester is to estimate available energy and power. This paper describes an estimation of the available power and energy due to the movements of the torso during breathing, using Doppler radar by detecting breathing rate, torso displacement, torso movement velocity and acceleration along the sagittal movement of the torso. The accuracy of the detected variables is verified by two reference methods. The experimental result obtained from a healthy female human subject shows that the available power from circumferential movement can be higher than the power from the sagittal movement.

    Introduction: Smokers’ health-related outcome expectancies are associated with a number of important constructs in smoking research, yet there are no measures currently available that focus exclusively on this domain. This paper describes the development and evaluation of item banks for assessing the health expectancies of smoking. Methods: Using data from a sample of daily (N = 4,201) and nondaily (N = 1,183) smokers, we conducted a series of item factor analyses, item response theory analyses, and differential item functioning analyses (according to gender, age, and race/ethnicity) to arrive at a unidimensional set of health expectancies items for daily and nondaily smokers. We also evaluated the performance of short forms (SFs) and computer adaptive tests (CATs) to efficiently assess health expectancies. Results: A total of 24 items were included in the Health Expectancies item banks; 13 items are common across daily and nondaily smokers, 6 are unique to daily, and 5 are unique to nondaily. For both daily and nondaily smokers, the Health Expectancies item banks are unidimensional, reliable (reliability = 0.95 and 0.96, respectively), and perform similarly across gender, age, and race/ethnicity groups. A SF common to daily and nondaily smokers consists of 6 items (reliability = 0.87). Results from simulated CATs showed that health expectancies can be assessed with good precision with an average of 5–6 items adaptively selected from the item banks. Conclusions: Health expectancies of smoking can be assessed on the basis of these item banks via SFs, CATs, or through a tailored set of items selected for a specific research purpose. PMID:25118229

  4. Quadratic Programming for Allocating Control Effort

    2005-01-01

    A computer program calculates an optimal allocation of control effort in a system that includes redundant control actuators. The program implements an iterative (but otherwise single-stage) algorithm of the quadratic-programming type. In general, in the quadratic-programming problem, one seeks the values of a set of variables that minimize a quadratic cost function, subject to a set of linear equality and inequality constraints. In this program, the cost function combines control effort (typically quantified in terms of energy or fuel consumed) and control residuals (differences between commanded and sensed values of variables to be controlled). In comparison with prior control-allocation software, this program offers approximately equal accuracy but much greater computational efficiency. In addition, this program offers flexibility, robustness to actuation failures, and a capability for selective enforcement of control requirements. The computational efficiency of this program makes it suitable for such complex, real-time applications as controlling redundant aircraft actuators or redundant spacecraft thrusters. The program is written in the C language for execution in a UNIX operating system.

  6. Sidoarjo mudflow phenomenon and its mitigation efforts

    2009-12-01

    Hot mud first erupted in Siring village, Porong, Sidoarjo May 29th 2006. The mud first appeared approximately 200 meters from Banjarpanji-1 gas-drilling well. The mud volume increased day by day, from 5000 cubic meters per day on June 2006 to 50,000 cubic meters per day during the last of 2006, and then increased to 100,000-120,000 cubic meters per day during 2007. Flow still continues at a high rate. Moreover, as the water content has gone down, the clast content has gone up. Consequently, there is now the threat of large amounts of solid material being erupted throughout the area. Also, there is the issue of subsurface collapse and ground surface subsidence. The Indonesian government has set up a permanent team to support communities affected by the mudflow that has swamped a number of villages near LUSI. Toll roads, railway tracks and factories also have been submerged and over 35,000 people have been displaced to date. The Sidoarjo Mudflow Mitigation Agency [SMMA, BPLS (Indonesia)] replaces a temporary team called National Team PSLS which was installed for seven months and ended their work on 7 April 2007. BPLS was set up by Presidential Regulation No. 14 / 2007, and it will have to cover the costs related to the social impact of the disaster, especially outside the swamped area. BPLS is the central government institution designated to handle the disaster by coordination with both the drilling company and local (provincial and district) governments. It takes a comprehensive, integrated and holistic approach for its mission and challenges. Those are: 1) How to stop the mudflow, 2) How to mitigate the impacts of the mudflow, and 3) How to minimize the social, economic, environmental impacts, and infrastructure impacts. The mudflow mitigation efforts were constrained by dynamic geology conditions, as well as resistance to certain measures by residents of impacted areas. Giant dykes were built to retain the spreading mud, and the mudflow from the main vent was diverted into the Porong River through a mud pump system. Also we continuously monitor changes in eruption behavior and try to anticipate the consequences, particularly after the Ring Dyke (of main vent) collapsed and became useless in controlling the flow. In September 2009 spectacular eruption intensity with kick and wave developed and is continuing. Surface and subsurface investigations continue ceaselessly to try to understand the forces driving the eruption. There are no precedents for mitigation of such a large scale mud volcano in a densely populated area that seems destined to continue for a very long time. This makes all efforts to stop eruption together with the emergency efforts, which have to be conducted simultaneously with recovery and reconstruction efforts that cover all basic needs of people live in the area. This is why BPLS has to develop innovative and creative efforts, mainly by applying the basic principle of learning by doing.

  7. Rapid Expectation Adaptation during Syntactic Comprehension

    2013-01-01

    When we read or listen to language, we are faced with the challenge of inferring intended messages from noisy input. This challenge is exacerbated by considerable variability between and within speakers. Focusing on syntactic processing (parsing), we test the hypothesis that language comprehenders rapidly adapt to the syntactic statistics of novel linguistic environments (e.g., speakers or genres). Two self-paced reading experiments investigate changes in readers’ syntactic expectations based on repeated exposure to sentences with temporary syntactic ambiguities (so-called “garden path sentences”). These sentences typically lead to a clear expectation violation signature when the temporary ambiguity is resolved to an a priori less expected structure (e.g., based on the statistics of the lexical context). We find that comprehenders rapidly adapt their syntactic expectations to converge towards the local statistics of novel environments. Specifically, repeated exposure to a priori unexpected structures can reduce, and even completely undo, their processing disadvantage (Experiment 1). The opposite is also observed: a priori expected structures become less expected (even eliciting garden paths) in environments where they are hardly ever observed (Experiment 2). Our findings suggest that, when changes in syntactic statistics are to be expected (e.g., when entering a novel environment), comprehenders can rapidly adapt their expectations, thereby overcoming the processing disadvantage that mistaken expectations would otherwise cause. Our findings take a step towards unifying insights from research in expectation-based models of language processing, syntactic priming, and statistical learning. PMID:24204909

    Improvements in attentional performance are at the core of proposed mechanisms for stress reduction in mindfulness meditation practices. However, this claim can be questioned because no previous studies have actively manipulated test effort in control groups and controlled for effects of stress reduction per se. In a blinded design, 48 young, healthy meditation novices were randomly assigned to a mindfulness-based stress reduction (MBSR), nonmindfulness stress reduction (NMSR), or inactive control group. At posttest, inactive controls were randomly split into nonincentive and incentive controls, the latter receiving a financial reward to improve attentional performance. Pre- and postintervention, 5 validated attention paradigms were employed along with self-report scales on mindfulness and perceived stress and saliva cortisol samples to measure physiological stress. Attentional effects of MBSR, NMSR, and the financial incentive were comparable or significantly larger in the incentive group on all reaction-time-based measures. However, selective attention in the MBSR group improved significantly more than in any other group. Similarly, only the MBSR intervention improved the threshold for conscious perception and visual working memory capacity. Furthermore, stress-reducing effects of MBSR were supported because those in the MBSR group showed significantly less perceived and physiological stress while increasing their mindfulness levels significantly. We argue that MBSR may contribute uniquely to attentional improvements but that further research focusing on non-reaction-time-based measures and outcomes less confounded by test effort is needed. Critically, our data demonstrate that previously observed improvements of attention after MBSR may be seriously confounded by test effort and nonmindfulness stress reduction. PMID:21910559

  9. Goals and task difficulty expectations modulate striatal responses to feedback.

    DePasque Swanson, Samantha; Tricomi, Elizabeth

    2014-06-01

    The striatum plays a critical role in learning from reward, and it has been implicated in learning from performance-related feedback as well. Positive and negative performance-related feedback is known to engage the striatum during learning by eliciting a response similar to the reinforcement signal for extrinsic rewards and punishments. Feedback is an important tool used to teach new skills and promote healthful lifestyle changes, so it is important to understand how motivational contexts can modulate its effectiveness at promoting learning. While it is known that striatal responses scale with subjective factors influencing the desirability of rewards, it is less clear how expectations and goals might modulate the striatal responses to cognitive feedback during learning. We used functional magnetic resonance imaging to investigate the effects of task difficulty expectations and achievement goals on feedback processing during learning. We found that individuals who scored high in normative goals, which reflect a desire to outperform other students academically, showed the strongest effects of our manipulation. High levels of normative goals were associated with greater performance gains and exaggerated striatal sensitivity to positive versus negative feedback during blocks that were expected to be more difficult. Our findings suggest that normative goals may enhance performance when difficulty expectations are high, while at the same time modulating the subjective value of feedback as processed in the striatum.

    NASA's CALIPSO satellite mission provides an array of opportunities for teachers, students, and the general public. In developing our latest plan for education and public outreach, CALIPSO focused on efforts that would support students as scientists. CALIPSO EPO activities are aimed at inspiring young scientists through multiple avenues of potential contact, including: educator professional development, student-scientist mentoring, curriculum resource development, and public outreach through collaborative mission efforts. In this session, we will explore how these avenues complement one another and take a closer look at the development of the educator professional development activities. As part of CALIPSO's EPO efforts, we have developed the GLOBE Atmosphere Investigations Programs (AIP). The program encourages students to engage in authentic science through research on the atmosphere. The National Research Council (NRC) has emphasized the importance of teaching scientific inquiry in the National Science Education Standards (1996, 2000) and scientific practice in the recent Framework for K-12 Science Education (2011). In order to encourage student-centered science inquiry, teacher training utilizing GLOBE Atmosphere Investigations and GLOBE's Student Research Process are provided to middle and high school teachers to assist them in incorporating real scientific investigations into their classroom. Through participation in the program, teachers become a part of GLOBE (Global Learning and Observations to Benefit the Environment) - an international community of teachers, students, and scientists studying environmental science in over 24,000 schools around the world. The program uses NASA's satellites and the collection of atmosphere data by students to provide an engaging science learning experience for the students, and teachers. The GLOBE Atmosphere Investigations program offers year-long support to both teachers and students through direct involvement with NASA activities. The program provides teachers with a one-week summer professional development workshop, long-term teacher support through classroom visits, teacher access to GLOBE instrumentation, and research opportunities for students. Professional development is centered on student engagement through inquiry, opportunities for collaborative student research, and the GLOBE Program's atmosphere protocols and learning activities. Beyond the training week, teachers receive follow-up specifically addressing current opportunities for student engagement in current research and opportunities for students to present research findings. The first cohort of teachers completed the professional development workshop in July 2012. This session will summarize the planning and implementation details of the summer workshop, including schedule and materials. In addition to these details, we will share our evaluation of follow-up activities and survey results highlighting teachers' perceived barriers to implementing atmosphere investigations. These results will add to the discussion on effective programs aimed at inspiring young scientists.

    We studied the mechanisms of task preparation using a design that pitted task expectancy against task repetition. In one experiment, two simple cognitive tasks were presented in a predictable sequence containing both repetitions and non-repetitions. The typical task sequence was AABBAABB. Occasional violations of this sequence allowed us to measure the effects of valid versus invalid expectancy. With this design, we were able to study the effects of task expectancy, task repetition, and interaction.

    Alexander, P.

    1985-01-01

    A summary of directed-energy process technology for solar cells was presented. This technology is defined as directing energy or mass to specific areas on solar cells to produce a desired effect in contrast to exposing a cell to a thermal or mass flow environment. Some of these second generation processing techniques are: ion implantation; microwave-enhanced chemical vapor deposition; rapid thermal processing; and the use of lasers for cutting, assisting in metallization, assisting in deposition, and drive-in of liquid dopants. Advantages of directed energy techniques are: surface heating resulting in the bulk of the cell material being cooler and unchanged; better process control yields; better junction profiles, junction depths, and metal sintering; lower energy consumption during processing and smaller factory space requirements. These advantages should result in higher-efficiency cells at lower costs. The results of the numerous contracted efforts were presented as well as the application potentials of these new technologies.

    Satellite observations of global ocean chlorophyll span over two decades. However, incompatibilities between processing algorithms prevent us from quantifying natural variability. We applied a comprehensive reanalysis to the Coastal Zone Color Scanner (CZCS) archive, called the NOAA-NASA CZCS Reanalysis (NCR) Effort. NCR consisted of 1) algorithm improvement (AI), where CZCS processing algorithms were improved using modernized atmospheric correction and bio-optical algorithms, and 2) blending, where in situ data were incorporated into the CZCS AI to minimize residual errors. The results indicated major improvement over the previously available CZCS archive. Global spatial and seasonal patterns of NCR chlorophyll indicated remarkable correspondence with modern sensors, suggesting compatibility. The NCR permits quantitative analyses of interannual and interdecadal trends in global ocean chlorophyll.

    In its report, Acid Rain Invades Our National Parks, the National Parks and Conservation Association (NPCA) says acid rain is being detected at all 27 national park monitoring sites. In 1980, 87 national parks expressed concern in a NPCA survey over acid rain. Repolled in 1986, more than half of the respondents reported that no research on acid rain was under way. The NPCA report concludes that the alarm that was sounded in 1980 fell largely on deaf ears, and calls for the structural and scientific reorganization of the National Park Service. The National Audubon Society shares NPCA's dissatisfaction with federal efforts to tackle the problem of acid rain and has taken testing into its own hands. Through its Citizens Acid Rain Monitoring Network, Audubon volunteers have collected readings of acidity at 64 monitoring stations in 31 states since July.

    The movements of the torso due to normal breathing could be harvested as an alternative, and renewable power source for an ultra-low power electronic device. The same output signal could also be recorded as a physiological signal containing information about breathing, thus enabling self-powered wearable biosensors/harvesters. In this paper, the selection criteria for such a biosensor, optimization procedure, trade-offs, and challenges as a sensor and harvester are presented. The empirical data obtained from testing different modules on a mechanical torso and a human subject demonstrated that an electromagnetic generator could be used as an unobtrusive self-powered medical sensor by harvesting more power, offering reasonable amount of output voltage for rectification purposes, and detecting respiratory effort.

  4. NREL Quickens its Tech Transfer Efforts

    SciTech Connect

    2012-02-01

    Innovations and 'aha' movements in renewable energy and energy efficiency, while exciting in the lab, only truly live up to their promise once they find a place in homes or business. Late last year President Obama issued a directive to all federal agencies to increase their efforts to transfer technologies to the private sector in order to achieve greater societal and economic impacts of federal research investments. The president's call to action includes efforts to establish technology transfer goals and to measure progress, to engage in efforts to increase the speed of technology transfer and to enhance local and regional innovation partnerships. But, even before the White House began its initiative to restructure the commercialization process, the National Renewable Energy Laboratory had a major effort underway designed to increase the speed and impact of technology transfer activities and had already made sure its innovations had a streamlined path to the private sector. For the last three years, NREL has been actively setting commercialization goals and tracking progress against those goals. For example, NREL sought to triple the number of innovations over a five-year period that began in 2009. Through best practices associated with inventor engagement, education and collaboration, NREL quadrupled the number of innovations in just three years. Similar progress has been made in patenting, licensing transactions, income generation and rewards to inventors. 'NREL is known nationally for our cutting-edge research and companies know to call us when they are ready to collaborate,' William Farris, vice president for commercialization and technology transfer, said. 'Once a team is ready to dive in, they don't want be mired in paperwork. We've worked to make our process for licensing NREL technology faster; it now takes less than 60 days for us to come to an agreement and start work with a company interested in our research.' While NREL maintains a robust patent portfolio, often companies are looking to do more than just license a technology. These relationships are invaluable in successfully moving technologies from NREL to the marketplace. 'We may generate new and potentially valuable innovations, but our commercialization partners do the heavy work of building a successful business around our technology,' Farris said. Tools such as CRADAs (Cooperative Research and Development Agreements) allow NREL to continue working with companies to refine and develop technologies. And, working with businesses is an area where NREL excels. NREL is responsible for one quarter of the CRADAs in the DOE system. 'When you look at the results of our CRADA program, you can demonstrate that we are actively engaged with companies in collaborating on research and moving technologies to market,' Farris said. NREL is first among DOE labs with 186 active CRADAs. And last year, NREL also was first with the number of new CRADAs signed. 'Part of the success in our working with industry goes back to NREL's mission to grow and support new industries,' Farris added. 'NREL has basic research capabilities, but we are never going to be the ultimate producer of a commercial product. That is the role of the private sector.' Farris also credits the advocacy and support that the Office of Energy Efficiency and Renewable Energy at DOE provides for these technology transfer activities. 'EERE's support is critical to our success,' Farris said. To assist the private sector in moving a technology from the lab to the manufacturing line, NREL has a number of programs in place to give that first, or even final, nudge toward commercialization. For instance, the Commercialization Assistance Program helps startups overcome technical barriers by granting free access to 40 hours of work at the lab. Through the Innovation and Entrepreneurship Center, NREL also helps clean energy businesses develop strong links with the financial community, as well as other key stakeholders in the commercialization process. In March, NREL formally opened the Colorado Center for Renewable Ene

    The National Aeronautics and Space Administration (NASA) formally initiated the Space Launch System (SLS) development in September 2011, with the approval of the program s acquisition plan, which engages the current workforce and infrastructure to deliver an initial 70 metric ton (t) SLS capability in 2017, while using planned block upgrades to evolve to a full 130 t capability after 2021. A key component of the acquisition plan is a three-phased approach for the first stage boosters. The first phase is to complete the development of the Ares and Space Shuttle heritage 5-segment solid rocket boosters (SRBs) for initial exploration missions in 2017 and 2021. The second phase in the booster acquisition plan is the Advanced Booster Risk Reduction and/or Engineering Demonstration NASA Research Announcement (NRA), which was recently awarded after a full and open competition. The NRA was released to industry on February 9, 2012, with a stated intent to reduce risks leading to an affordable advanced booster and to enable competition. The third and final phase will be a full and open competition for Design, Development, Test, and Evaluation (DDT&E) of the advanced boosters. There are no existing boosters that can meet the performance requirements for the 130 t class SLS. The expected thrust class of the advanced boosters is potentially double the current 5-segment solid rocket booster capability. These new boosters will enable the flexible path approach to space exploration beyond Earth orbit (BEO), opening up vast opportunities including near-Earth asteroids, Lagrange Points, and Mars. This evolved capability offers large volume for science missions and payloads, will be modular and flexible, and will be right-sized for mission requirements. NASA developed the Advanced Booster Engineering Demonstration and/or Risk Reduction NRA to seek industry participation in reducing risks leading to an affordable advanced booster that meets the SLS performance requirements. Demonstrations and/or risk reduction efforts were required to be related to a proposed booster concept directly applicable to fielding an advanced booster. This paper will discuss, for the first time publicly, the contract awards and how NASA intends to use the data from these efforts to prepare for the planned advanced booster DDT&E acquisition as the SLS Program moves forward with competitively procured affordable performance enhancements.

    2014-02-12

    Systems engineering is an interdisciplinary approach and means to enable the realization of successful systems. In this study, systems engineering approach towards the performance monitoring of Emergency Diesel Generator (EDG) is presented. Performance monitoring is part and parcel of predictive maintenance where the systems and components conditions can be detected before they result into failures. In an effort to identify the proposal for addressing performance monitoring, the EDG boundary has been defined. Based on the Probabilistic Safety Analysis (PSA) results and industry operating experiences, the most critical component is identified. This paper proposed a systems engineering concept development framework towards EDG performance monitoring. The expected output of this study is that the EDG reliability can be improved by the performance monitoring alternatives through the systems engineering concept development effort.

  8. Musculoskeletal pain and effort-reward imbalance- a systematic review

    PubMed Central

    2014-01-01

    Background Musculoskeletal pain may be triggered by physical strains and psychosocial risk factors. The effort-reward imbalance model (ERI model) is a stress model which measures psychosocial factors in the working world. The question is whether workers with an effort-reward imbalance report musculoskeletal pain more frequently than those with no effort-reward imbalance. A systematic review using a best evidence synthesis approach was conducted to answer this question. Methods A literature search was conducted for the period from 1996 to 2012, using three databases (Pubmed, Embase and PsycINFO). The research criteria related to psychosocial, work-related stress as per the ERI model and to musculoskeletal pain. A quality score was developed using various quality criteria to assess the standard of the studies. The level of evidence was graded as in (Am J Ind Med 39:180–193, 2001). Results After applying the inclusion criteria, a total of 19 studies were included in the review: 15 cross-sectional studies, three prospective studies and one case–control study. 74% of all studies exhibited good methodological quality, 53% collected data using the original ERI questionnaire, and in 42% of the studies, there was adequate control for physical working conditions. Furthermore, different cut-off points were used to classify exposed and non-exposed individuals. On the basis of 13 studies with a positive, statistically significant association, a moderate level of evidence was inferred for the association between effort-reward imbalance and musculoskeletal pain. The evidence for a role of over-commitment and for its interaction with effort-reward imbalance was rated as inconclusive - on the basis of eight and five studies, respectively. Conclusions On the basis of the available evidence, no reliable conclusion may be drawn about any association between the psychosocial factors ascertained using the ERI model and musculoskeletal pain. Before a reliable statement can be made on the association between ERI and musculoskeletal pain, additional longitudinal studies must be performed - with a standardised method for recording and classifying exposure, as well as control of physical confounders. Appropriate preventive measures can then be specified. PMID:24428955

  9. Using expectations to monitor robotic progress and recover from problems

    2013-05-01

    How does a robot know when something goes wrong? Our research answers this question by leveraging expectations - predictions about the immediate future - and using the mismatch between the expectations and the external world to monitor the robot's progress. We use the cognitive architecture ACT-R (Adaptive Control of Thought - Rational) to learn the associations between the current state of the robot and the world, the action to be performed in the world, and the future state of the world. These associations are used to generate expectations that are then matched by the architecture with the next state of the world. A significant mismatch between these expectations and the actual state of the world indicate a problem possibly resulting from unexpected consequences of the robot's actions, unforeseen changes in the environment or unanticipated actions of other agents. When a problem is detected, the recovery model can suggest a number of recovery options. If the situation is unknown, that is, the mismatch between expectations and the world is novel, the robot can use a recovery solution from a set of heuristic options. When a recovery option is successfully applied, the robot learns to associate that recovery option with the mismatch. When the same problem is encountered later, the robot can apply the learned recovery solution rather than using the heuristics or randomly exploring the space of recovery solutions. We present results from execution monitoring and recovery performed during an assessment conducted at the Combined Arms Collective Training Facility (CACTF) at Fort Indiantown Gap.

  10. Gender differences in healthy life expectancy among Brazilian elderly

    PubMed Central

    2014-01-01

    Background This study examined gender differences in healthy life expectancy (HLE) and unhealthy life expectancy (UHLE) among people aged 60 years or older living in a large Brazilian city. Methods Based on Chiang method, abridged life tables were constructed for men and for women. To calculate HLE, the Sullivan method was applied. Estimates of the prevalence of self-rated health and self-reported functional disability (global, mild/moderate, and severe) were obtained from a population-based household survey carried out in 2008, which involved non-institutionalized individuals. Results Findings showed that women live longer and these extra years would be spent in good self-rated health. For example, women aged 60 would live, on average, 4 more years in good health in comparison to men. In terms of global limitations and mild/moderate limitations, no gender differences were detected for HLE. However, UHLE was statistically higher among women than among men at all ages in the global limitations and mild/moderate limitations (except for the age 80). Women at age 60, for instance, could expect to live 3.1 years longer with mild/moderate limitations compared to men. Gender differences were identified for severe limitations for either HLE or UHLE. In comparison to men, women at age 60, for example, would expect to live 2.5 and 2.0 more years without and with severe limitations. Conclusions By showing that the advantage of longer life expectancy among women is not necessarily accompanied by worse health conditions, these findings add some evidence to the debate about male-female health-survival paradox. Policy efforts are necessary to reduce gender differences in the quantity and quality of years to be lived, providing equal opportunities to women and men live longer with quality of life, autonomy, and independence.

  18. Alcohol expectancies in a Native American population.

    PubMed

    Garcia-Andrade, C; Wall, T L; Ehlers, C L

    1996-11-01

    Native Americans, as a group, have a high prevalence of alcohol abuse and alcohol dependence, although specific risk factors for alcoholism among this population have yet to be clearly identified. One set of factors that may contribute to the development of alcoholism are expectations of alcohol's effects. Previous research has shown that heavy drinkers and alcoholics have higher alcohol-related expectancies. Some studies have also shown an association between alcohol expectancies and a positive familial history of alcoholism. To examine factors that are related to expectations of alcohol's effects in a Native American population, this study evaluated healthy, nonalcoholic Mission Indian men between the ages of 18 and 25 years using the short form of the Alcohol Expectancy Questionnaire (AEQ). The influence of recent drinking history, family history of alcoholism, and degree of Native American heritage on alcohol-related expectancies was determined using regression analyses for the total AEQ score and for each of the six AEQ subscales. Recent drinking history accounted for a significant proportion of the variance in the total score, as well as scale I (global positive changes) and scale VI (arousal and power) of the AEQ. Degree of Native American heritage and family history of alcoholism did not account for a significant amount of variability in alcohol expectancies. These results suggest that, consistent with findings in other populations, alcohol expectancies are related to drinking patterns in Mission Indians. However, no association with two other potential risk factors were found in this sample of Native Americans. PMID:8947322

    The cardiovascular responses to combined static-dynamic effort, postprandial dynamic effort and dynamic effort alone were evaluated by upright bicycle ergometry during equilibrium-gated blood pool scintigraphy in 24 men, mean age 59 +/- 8 years, with chronic ischemic heart disease. Combined static-dynamic effort and the postprandial state elicited a peak cardiovascular response similar to that of dynamic effort alone. Heart rate, intraarterial systolic and diastolic pressures, rate-pressure product and ejection fraction were similar for the three test conditions at the onset of ischemia and at peak effort. The prevalence and extent of exercise-induced ischemic left ventricular dysfunction, ST-segment depression, angina pectoris and ventricular ectopic activity were also similar during the three test conditions. Direct and indirect measurements of systolic and diastolic blood pressure were highly correlated. The onset of ischemic ST-segment depression and angina pectoris correlated as strongly with heart rate alone as with the rate-pressure product during all three test conditions. The cardiovascular response to combined static-dynamic effort and to postprandial dynamic effort becomes more similar to that of dynamic effort alone as dynamic effort reaches a symptom limit. If significant ischemic and arrhythmic abnormalities are absent during symptom-limited dynamic exercise testing, they are unlikely to appear during combined static-dynamic or postprandial dynamic effort.

    2004-06-18

    The requirements of the Government Performance and Results Act (GPRA) of 1993 mandate the reporting of outcomes expected to result from programs of the Federal government. The U.S. Department of Energy’s (DOE’s) Office of Energy Efficiency and Renewable Energy (EERE) develops official metrics for its 11 major programs using its Office of Planning, Budget Formulation, and Analysis (OPBFA). OPBFA conducts an annual integrated modeling analysis to produce estimates of the energy, environmental, and financial benefits expected from EERE’s budget request. Two of EERE’s major programs include the Building Technologies Program (BT) and Office of Weatherization and Intergovernmental Program (WIP). Pacific Northwest National Laboratory (PNNL) supports the OPBFA effort by developing the program characterizations and other market information affecting these programs that is necessary to provide input to the EERE integrated modeling analysis. Throughout the report we refer to these programs as “buildings-related” programs, because the approach is not limited in application to BT or WIP. To adequately support OPBFA in the development of official GPRA metrics, PNNL communicates with the various activities and projects in BT and WIP to determine how best to characterize their activities planned for the upcoming budget request. PNNL then analyzes these projects to determine what the results of the characterizations would imply for energy markets, technology markets, and consumer behavior. This is accomplished by developing nonintegrated estimates of energy, environmental, and financial benefits (i.e., outcomes) of the technologies and practices expected to result from the budget request. These characterizations and nonintegrated modeling results are provided to OPBFA as inputs to the official benefits estimates developed for the Federal Budget. This report documents the approach and methodology used to estimate future energy, environmental, and financial benefits produced by technologies and practices supported by BT and by WIP. However, the approach is general enough for analysis of buildings-related technologies, independent of any specific program. An overview describes the GPRA process and the models used to estimate energy savings. The body of the document describes the algorithms used and the diffusion curve estimates.

    The basal ganglia may play an important role in the control of motor scaling or effort. Recently local field potential (LFP) recordings from patients with deep brain stimulation electrodes in the basal ganglia have suggested that local increases in the synchronisation of neurons in the gamma frequency band may correlate with force or effort. Whether this feature uniquely codes for effort and whether such a coding mechanism holds true over a range of efforts is unclear. Here we investigated the relationship between frequency-specific oscillatory activities in the subthalamic nucleus (STN) and manual grips made with different efforts. The latter were self-rated using the 10 level Borg scale ranging from 0 (no effort) to 10 (maximal effort). STN LFP activities were recorded in patients with Parkinson's Disease (PD) who had undergone functional surgery. Patients were studied while motor performance was improved by dopaminergic medication. In line with previous studies we observed power increase in the theta/alpha band (4–12 Hz), power suppression in the beta band (13–30 Hz) and power increase in the gamma band (55–90 Hz) and high frequency band (101–375 Hz) during voluntary grips. Beta suppression deepened, and then reached a floor level as effort increased. Conversely, gamma and high frequency power increases were enhanced during grips made with greater effort. Multiple regression models incorporating the four different spectral changes confirmed that the modulation of power in the beta band was the only independent predictor of effort during grips made with efforts rated < 5. In contrast, increases in gamma band activity were the only independent predictor of effort during grips made with efforts ? 5. Accordingly, the difference between power changes in the gamma and beta bands correlated with effort across all effort levels. These findings suggest complementary roles for changes in beta and gamma band activities in the STN in motor effort coding. The latter function is thought to be impaired in untreated PD where task-related reactivity in these two bands is deficient. PMID:23778147

    Sodium intake reduction efforts in Lebanon are quite recent and have just started to take effect on the national level. Starting out from an academic institution, the Lebanese Action on Sodium and Health (LASH) campaign was established to counter the increasing prevalence of hypertension and associated adverse health effects. The campaign’s strategy was based on four pillars: research, health communication, advocacy, and monitoring. The LASH group set out with determining: baseline sodium intake of the population, main sources of sodium intake, and the knowledge, attitudes, and behaviors (KAB) of the population as a situation analysis that prompts for action. This gave LASH tangible evidence of the magnitude of the problem and the need for the government, the food industry, and the consumers, to be mobilized to take part in devising a solution. Currently, Lebanon is at a stage of technically working to reduce the sodium content in the major sources of sodium, namely local bread and bread-like products. The next steps will include implementation of a plan for monitoring industry compliance, while studying other food targets, including dairy products and processed meat. Meanwhile, the health communication plan is ongoing and the Salt Awareness Week is celebrated every year with media appearances of LASH researchers to raise the issue to the public eye.

    According to the National Science Foundation, of the more than 4 million first university degrees awarded in science and engineering in 2006, students in China earned about 21%, those in the European Union earned about 19%, and those in the United States earned about 11%. Statistics like these are of great interest to NASA's Ares Projects, which are responsible for building the rockets for the U.S. Constellation Program to send humans beyond low-Earth orbit. Science, technology, engineering, and mathematics students are essential for the long-term sustainability of any space program. Since the Projects creation, the Ares Outreach Team has used a variety of STEM-related media, methods, and materials to engage students, educators, and the general public in Constellation's mission. Like Project Apollo, the nation s exploration destinations and the vehicles used to get there can inspire students to learn more about STEM. Ares has been particularly active in public outreach to schools in Northern Alabama; on the Internet via outreach and grade-specific educational materials; and in more informal social media settings such as YouTube and Facebook. These combined efforts remain integral to America s space program, regardless of its future direction.

  7. Obtaining information by dynamic (effortful) touching

    Turvey, M. T.; Carello, Claudia

    2011-01-01

    Dynamic touching is effortful touching. It entails deformation of muscles and fascia and activation of the embedded mechanoreceptors, as when an object is supported and moved by the body. It is realized as exploratory activities that can vary widely in spatial and temporal extents (a momentary heft, an extended walk). Research has revealed the potential of dynamic touching for obtaining non-visual information about the body (e.g. limb orientation), attachments to the body (e.g. an object's height and width) and the relation of the body both to attachments (e.g. hand's location on a grasped object) and surrounding surfaces (e.g. places and their distances). Invariants over the exploratory activity (e.g. moments of a wielded object's mass distribution) seem to ground this ‘information about’. The conception of a haptic medium as a nested tensegrity structure has been proposed to express the obtained information realized by myofascia deformation, by its invariants and transformations. The tensegrity proposal rationalizes the relative indifference of dynamic touch to the site of mechanical contact (hand, foot, torso or probe) and the overtness of exploratory activity. It also provides a framework for dynamic touching's fractal nature, and the finding that its degree of fractality may matter to its accomplishments. PMID:21969694

    The ability to perform effortful tasks is a topic that has received considerable interest in the research of higher functions of the human brain. Neuroimaging studies show that the anterior insular and the anterior cingulate cortices are involved in a multitude of cognitive tasks that require mental effort. In this study, we investigated brain responses to effort using cognitive tasks with task-difficulty modulations and functional magnetic resonance imaging (fMRI). We hypothesized that effortful performance involves modulation of activation in the anterior insular and the anterior cingulate cortices, and that the modulation correlates with individual performance levels. Healthy participants performed tasks probing verbal working memory capacity using the reading span task, and visual perception speed using the inspection time task. In the fMRI analysis, we focused on identifying effort-related brain activation. The results showed that working memory and inspection time performances were directly related. The bilateral anterior insular and anterior cingulate cortices showed significantly increased activation during each task with common portions that were active across both tasks. We observed increased brain activation in the right anterior insula and the anterior cingulate cortex in participants with low working memory performance. In line with the reported results, we suggest that activation in the anterior insular and cingulate cortices is consistent with the neural efficiency hypothesis (Neubauer). PMID:25674057

    Quantum communication between nodes in quantum networks plays an important role in quantum information processing. Here, we proposed the use of the expected number of quantum channels as a measure of the efficiency of quantum communication for quantum networks. This measure quantified the amount of quantum information that can be teleported between nodes in a quantum network, which differs from classical case in that the quantum channels will be consumed if teleportation is performed. We further demonstrated that the expected number of quantum channels represents local correlations depicted by effective circles. Significantly, capacity of quantum communication of quantum networks quantified by ENQC is independent of distance for the communicating nodes, if the effective circles of communication nodes are not overlapped. The expected number of quantum channels can be enhanced through transformations of the lattice configurations of quantum networks via entanglement swapping. Our results can shed lights on the study of quantum communication in quantum networks. PMID:26173556

    2006-02-08

    The Naval Reactors Program led work on the development of a reactor plant system for the Prometheus space reactor program. The work centered on a 200 kWe electric reactor plant with a 15-20 year mission applicable to nuclear electric propulsion (NEP). After a review of all reactor and energy conversion alternatives, a direct gas Brayton reactor plant was selected for further development. The work performed subsequent to this selection included preliminary nuclear reactor and reactor plant design, development of instrumentation and control techniques, modeling reactor plant operational features, development and testing of core and plant material options, and development of an overall project plan. Prior to restructuring of the program, substantial progress had been made on defining reference plant operating conditions, defining reactor mechanical, thermal and nuclear performance, understanding the capabilities and uncertainties provided by material alternatives, and planning non-nuclear and nuclear system testing. The mission requirements for the envisioned NEP missions cannot be accommodated with existing reactor technologies. Therefore concurrent design, development and testing would be needed to deliver a functional reactor system. Fuel and material performance beyond the current state of the art is needed. There is very little national infrastructure available for fast reactor nuclear testing and associated materials development and testing. Surface mission requirements may be different enough to warrant different reactor design approaches and development of a generic multi-purpose reactor requires substantial sacrifice in performance capability for each mission.

  18. Cost/Effort Drivers and Decision Analysis

    2010-01-01

    Engineering trade study analyses demand consideration of performance, cost and schedule impacts across the spectrum of alternative concepts and in direct reference to product requirements. Prior to detailed design, requirements are too often ill-defined (only goals ) and prone to creep, extending well beyond the Systems Requirements Review. Though lack of engineering design and definitive requirements inhibit the ability to perform detailed cost analyses, affordability trades still comprise the foundation of these future product decisions and must evolve in concert. This presentation excerpts results of the recent NASA subsonic Engine Concept Study for an Advanced Single Aisle Transport to demonstrate an affordability evaluation of performance characteristics and the subsequent impacts on engine architecture decisions. Applying the Process Based Economic Analysis Tool (PBEAT), development cost, production cost, as well as operation and support costs were considered in a traditional weighted ranking of the following system-level figures of merit: mission fuel burn, take-off noise, NOx emissions, and cruise speed. Weighting factors were varied to ascertain the architecture ranking sensitivities to these performance figures of merit with companion cost considerations. A more detailed examination of supersonic variable cycle engine cost is also briefly presented, with observations and recommendations for further refinements.

    2013-12-01

    This study employs the 2004 School Achievement Indicators Program (SAIP) data to examine whether academic effort manifested by greater investments in school and homework does result in higher literacy scores in science for Canadian students. The study compares four gender-immigrant profiles: Canadian-born males, immigrant males, Canadian-born females, and immigrant females on their scores on teacher-assigned grades in science and on the SAIP science literacy test, and across a range of dispositions, beliefs, and behaviors suggested in the literature as predictive of achievement in science. Study findings show that Canadian-born students, particularly boys, have higher performance in the science literacy test despite their lower achievement in the science classroom and the least investments of time in doing science homework. In contrast, immigrant female students demonstrate the highest academic effort and achievement in science courses which are not matched by similar results in the science literacy test. We discuss these results in relation to different socialization experiences with science and technology that limit female and immigrant students' abilities to transfer knowledge to new situations that have not been learned in the classroom.

  2. 1996 Design effort for IFMIF HEBT

    The paper details the 1996 design effort for the IFMIF HEBT. Following a brief overview, it lists the primary requirements for the beam at the target, describes the design approach and design tools used, introduces the beamline modules, gives the results achieved with the design at this stage, points out possible improvements and gives the names and computer locations of the TRACE3-D and PARMILA files that sum up the design work. The design does not fully meet specifications in regards to the flatness of the distribution at the target. With further work, including if necessary some backup options, the flatness specifications may be realized. It is not proposed that the specifications, namely flatness to {+-}5% and higher-intensity ridges that are no more than 15% above average, be changed at this time. The design also does not meet the requirement that the modules of all beamlines should operate at the same settings. However, the goal of using identical components and operational procedures has been met and only minor returning is needed to produce very similar beam distributions from all beamlines. Significant further work is required in the following areas: TRACE3-D designs and PARMILA runs must be made for the beams coming from accelerators No. 3 and No. 4. Transport of 30-MeV and 35-MeV beams to the targets and beam dump must be studied. Comprehensive error studies must be made. These must result in tolerance specifications and may require design iterations. Detailed interfacing with target-spot instrumentation is required. This instrumentation must be able to check all aspects of the specifications.

    The marriage of toxicology and genomics has created not only opportunities but also novel informatics challenges. As with the larger field of gene expression analysis, toxicogenomics faces the problems of probe annotation and data comparison across different array platforms. Toxicogenomics studies are generally built on standard toxicology studies generating biological end point data, and as such, one goal of toxicogenomics is to detect relationships between changes in gene expression and in those biological parameters. These challenges are best addressed through data collection into a well-designed toxicogenomics database. A successful publicly accessible toxicogenomics database will serve as a repository for data sharing and as a resource for analysis, data mining, and discussion. It will offer a vehicle for harmonizing nomenclature and analytical approaches and serve as a reference for regulatory organizations to evaluate toxicogenomics data submitted as part of registrations. Such a database would capture the experimental context of in vivo studies with great fidelity such that the dynamics of the dose response could be probed statistically with confidence. This review presents the collaborative efforts between the European Molecular Biology Laboratory-European Bioinformatics Institute ArrayExpress, the International Life Sciences Institute Health and Environmental Science Institute, and the National Institute of Environmental Health Sciences National Center for Toxigenomics Chemical Effects in Biological Systems knowledge base. The goal of this collaboration is to establish public infrastructure on an international scale and examine other developments aimed at establishing toxicogenomics databases. In this review we discuss several issues common to such databases: the requirement for identifying minimal descriptors to represent the experiment, the demand for standardizing data storage and exchange formats, the challenge of creating standardized nomenclature and ontologies to describe biological data, the technical problems involved in data upload, the necessity of defining parameters that assess and record data quality, and the development of standardized analytical approaches.

  7. Do infants really expect agents to act efficiently? A critical test of the rationality principle

    PubMed Central

    Scott, Rose M.; Baillargeon, Renée

    2013-01-01

    Recent experiments suggest that infants’ expectations about agents’ actions are guided by a principle of rationality: in particular, infants expect agents to pursue their goals efficiently, expending as little effort as possible. However, these experiments have all presented infants with infrequent or odd actions, leaving the results open to alternative interpretations and making it difficult to determine whether infants possess a general expectation of efficiency. Here we devised a critical test of the rationality principle that did not involve infrequent or odd actions. In two experiments, 16-month-olds watched events in which an agent faced two identical goal objects; although both objects could be reached by typical, everyday actions, one object was physically (Experiment 1) or mentally (Experiment 2) more accessible than the other. In both experiments, infants expected the agent to select the more accessible object, providing new evidence that infants possess a general and robust expectation of efficiency. PMID:23470355

    This article reports on a longitudinal test of a developmental model of early smoking that specifies reciprocal predictive relationships between smoking expectancies and smoking behavior in youth. The model was tested on 1,906 children during the transition from elementary school to middle school across 3 time points: the spring of 5th grade, the fall of 6th grade, and the spring of 6th grade. Key findings were (a) elementary school expectancies for reinforcement from smoking predicted smoking behavior during middle school; (b) smoking experience predicted increased subsequent smoking expectancies; and (c) among children who had never smoked, smoking expectancies predicted subsequent smoking onset. The finding that smoking expectancies and smoking behavior predicted each other reciprocally and positively across time in children this young may prove important in developing and refining early intervention and prevention efforts.

    1989-12-01

    Projects supported by the Directorate for Population (S&T/POP) of the U.S. Agency for International Development and aimed at increasing for-profit private sector involvement in providing family planning services and products are described. Making products commercially available through social-marketing partnerships with the commercial sector, USAID has saved $1.1 million in commodity costs from Brazil, Dominican Republic, Ecuador, Indonesia, and Peru. Active private sector involvement benefits companies, consumers, and donors through increased corporate profits, healthier employees, improved consumer access at lower cost, and the possibility of sustained family planning programs. Moreover, private, for-profit companies will be able to meet service demands over the next 20 years where traditional government and donor agency sources would fail. Using employee surveys and cost-benefit analyses to demonstrate expected financial and health benefits for businesses and work forces, S&T/POP's Technical Information on Population for the Private Sector (TIPPS) project encourages private companies in developing countries to invest in family planning and maternal/child health care for their employees. 36 companies in 9 countries have responded thus far, which examples provided from Peru and Zimbabwe. The Enterprise program's objectives are also to increase the involvement of for-profit companies in delivering family planning services, and to improve the efficiency and effectiveness of private volunteer organizations in providing services. Projects have been started with mines, factories, banks, insurance companies, and parastatals in 27 countries, with examples cited from Ghana and Indonesia. Finally, the Social Marketing for Change project (SOMARC) builds demand and distributes low-cost contraceptives through commercial channels especially to low-income audiences. Partnerships have been initiated with the private sector in 17 developing countries, with examples provided from the Dominican Republic, Liberia and Ecuador. These projects have increased private sector involvement in family planning, thereby promoting service expansion at lower public sector cost. PMID:12343476

    1989-01-01

    With today's lower mortality rates, longer expectations of life, and new medical technologies, the nation's health policy focus has shifted from emphasis on individual survival to emphasis on personal health and independent living. Using longitudinal data sets and new methodological techniques, researchers have begun to assess active life expectancies, estimating not only how long a subpopulation can expect to live beyond each age, but what fractions of the expected remaining lifetime will be lived as independent, dependent, or institutionalized. New ideas are addressed, applying recently developed multistate life table methods to Waves One and Two of the Massachusetts Health Care Panel Study. Expectations of active life are presented for those 65 and older who initially are in one of two functional states of well-being. Included are expectations of life, for those, for example, who were independent and remained so, or those who were dependent and became independent. Although public health officials are concerned about the number of elderly who cease being independent, preliminary analysis shows that a significant number of the dependent elderly regain their independence, a situation which needs to be addressed in health care planning.

    2004-08-01

    Pre-launch testing is essential to adequately verify hardware of Agency programmes with respect to functionality, performance, and space environment compatibility. Such verification requires the provision of test facilities, and the ESA Test Centre provides the largest and most powerful set of test facilities in Europe. The main facilities at ESTEC are unique and therefore indispensable for European Space programmes e.g. the Large Space Simulator (LSS) the Large European Acoustic Facility (LEAF), the large 6 axis hydraulic shaker HYDRA, And the new large EMC test facility MAXWELL. This paper discusses the main facilities at ESTEC, aspects of the Coordinated European Test Facilities (CETeF) and aspects of effective testing.

  11. Predicting Life Expectancy in Men Diagnosed with Prostate Cancer

    PubMed Central

    Sammon, Jesse D.; Abdollah, Firas; D'amico, Anthony; Gettman, Matthew; Haese, Alexander; Suardi, Nazareno; Vickers, Andrew; Trinh, Quoc-Dien

    2015-01-01

    Context The widespread use of prostate specific antigen (PSA) screening, has lead to the detection of more indolent prostate cancer (CaP) in healthy men. Prostate cancer treatment and screening must therefore balance the potential for life gained vs. the potential for harm. Fundamental to this balance is physician awareness of a patient's estimated life expectancy. Objective To review the evidence on life expectancy (LE) differences between men diagnosed with CaP and the general population. To examine clinician and model predicted LE and examine publicly available LE calculators Evidence Acquisition A comprehensive search of the PubMed database between 1990 and September 2014 was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement guidelines. Free text protocols of the following search terms were used “life expectancy prostate cancer”, “life expectancy non-cancer”, “non-cancer mortality prostate”, “comorbidity-adjusted life expectancy”. Two internet search engines were queried daily, for one month, for the search term “life expectancy calculator”, and the top 20 results were examined. Evidence Synthesis Of 992 articles and 32 websites screened, 17 articles and 9 websites were selected for inclusion. Men with non-screening detected CaP, as well as distant disease at diagnosis, were found to have a shorter LE than age-matched peers, whereas men with localized CaP had a prolonged LE. In general, clinician-predicted 10-yr LE was pessimistic and of limited accuracy, however model-predicted LE provided only modest improvements in accuracy (c-index of models: 0.65-0.84). Online LE calculators vary in ease of use, but government life tables provide LE estimates near the mean of all examined calculators. Conclusion The accuracy of clinician-predicted survival is limited and while available statistical models offer improvement in discrimination, it is unclear that they provide advantages over freely available government life-tables. Patient Summary In this report we examine the differences in life expectancy for men diagnosed with prostate cancer compared to the general population and ways of predicting life expectancy to help guide treatment decisions. We found that current models of predicting life expectancy, specific to prostate cancer, might not be any better than government life tables or simple rules-of-thumb. PMID:25819724

  15. Reinvigorating stalled CQI efforts through physician involvement.

    PubMed

    Lewis, A

    1993-01-01

    Continuous quality improvement (CQI), loosely synonymous with total quality management (TQM), was designed for the comparatively simple world of industry. Now that the gurus of CQI have attempted--originally with full support of the Joint Commission on Accreditation of Healthcare Organizations (JCAHO)--to apply the industrial CQI model to hospitals, they've noticed something: The model doesn't work, and hospital CQI programs are faltering enough to persuade the Joint Commission to scale back its CQI accreditation requirements. One major shortcoming behind the performance to date of CQI in hospitals: Physicians don't fit into the industrial model of CQI. Physicians are too important, and too many programs are stalled, to continue to implement CQI as though physicians don't exist. The techniques described here should help to reinvigorate faltering programs, giving hospital management a chance to "do it right the second time." PMID:10127411

  16. Scientometrics of drug discovery efforts: pain-related molecular targets

    PubMed Central

    Kissin, Igor

    2015-01-01

    The aim of this study was to make a scientometric assessment of drug discovery efforts centered on pain-related molecular targets. The following scientometric indices were used: the popularity index, representing the share of articles (or patents) on a specific topic among all articles (or patents) on pain over the same 5-year period; the index of change, representing the change in the number of articles (or patents) on a topic from one 5-year period to the next; the index of expectations, representing the ratio of the number of all types of articles on a topic in the top 20 journals relative to the number of articles in all (>5,000) biomedical journals covered by PubMed over a 5-year period; the total number of articles representing Phase I–III trials of investigational drugs over a 5-year period; and the trial balance index, a ratio of Phase I–II publications to Phase III publications. Articles (PubMed database) and patents (US Patent and Trademark Office database) on 17 topics related to pain mechanisms were assessed during six 5-year periods from 1984 to 2013. During the most recent 5-year period (2009–2013), seven of 17 topics have demonstrated high research activity (purinergic receptors, serotonin, transient receptor potential channels, cytokines, gamma aminobutyric acid, glutamate, and protein kinases). However, even with these seven topics, the index of expectations decreased or did not change compared with the 2004–2008 period. In addition, publications representing Phase I–III trials of investigational drugs (2009–2013) did not indicate great enthusiasm on the part of the pharmaceutical industry regarding drugs specifically designed for treatment of pain. A promising development related to the new tool of molecular targeting, ie, monoclonal antibodies, for pain treatment has not yet resulted in real success. This approach has not yet demonstrated clinical effectiveness (at least with nerve growth factor) much beyond conventional analgesics, when its potential cost is more than an order of magnitude higher than that of conventional treatments. This scientometric assessment demonstrated a lack of real breakthrough developments. PMID:26170624

  17. EXPECT: Explicit Representations for Flexible Acquisition

    NASA Technical Reports Server (NTRS)

    Swartout, BIll; Gil, Yolanda

    1995-01-01

    To create more powerful knowledge acquisition systems, we not only need better acquisition tools, but we need to change the architecture of the knowledge based systems we create so that their structure will provide better support for acquisition. Current acquisition tools permit users to modify factual knowledge but they provide limited support for modifying problem solving knowledge. In this paper, the authors argue that this limitation (and others) stem from the use of incomplete models of problem-solving knowledge and inflexible specification of the interdependencies between problem-solving and factual knowledge. We describe the EXPECT architecture which addresses these problems by providing an explicit representation for problem-solving knowledge and intent. Using this more explicit representation, EXPECT can automatically derive the interdependencies between problem-solving and factual knowledge. By deriving these interdependencies from the structure of the knowledge-based system itself EXPECT supports more flexible and powerful knowledge acquisition.

  18. Information structure expectations in sentence comprehension

    PubMed Central

    Carlson, Katy; Dickey, Michael Walsh; Frazier, Lyn; Clifton, Charles

    2009-01-01

    In English, new information typically appears late in the sentence, as does primary accent. Because of this tendency, perceivers might expect the final constituent or constituents of a sentence to contain informational focus. This expectation should in turn affect how they comprehend focus-sensitive constructions such as ellipsis sentences. Results from four experiments on sluicing sentences (e.g., The mobster implicated the thug, but we can’t find out who else) suggest that perceivers do prefer to place focus late in the sentence, though that preference can be mitigated by prosodic information (pitch accents, Experiment 2) or syntactic information (clefted sentences, Experiment 3) indicating that focus is located elsewhere. Furthermore, it is not necessarily the direct object, but the informationally-focused constituent that is the preferred antecedent (Experiment 4). Expectations regarding the information structure of a sentence, which are only partly cancelable by means of overt focus markers, may explain persistent biases in ellipsis resolution. PMID:18609404

    2011-01-01

    When care providers support their personal worth, use caring communication, facilitate consumer participation in decision making, seek optimal outcomes, and know the patient holistically, female patients feel that their dignity is respected. We compare women's expectations for dignified care in contemporary society with the expectations of women 40 years ago. Some progress has been made toward valuing women's voices and participation in decision making, the availability of interventions for optimal outcomes, and recognition of the importance of cultural competence. Continued work is needed to meet women's expectations for receiving individualized and tailored care, information about intervention effectiveness and risks, and support for the birth process that the family desires. A renewed focus on the recipient of care as a coparticipant in her birthing experiences may result in improved outcomes and resolution of tensions between childbearing women and sociopolitical forces and standards of care.

  20. Towards a Better Earthquake and Tsunami Monitoring System: Indian Effort

    NASA Astrophysics Data System (ADS)

    Bansal, B.; Gupta, G.

    2005-12-01

    The December 26, 2004 earthquake (mw 9.3) in the Andaman-Sumatra subduction zone was unprecedented in its size, rupture extent as well as tsunamigenic capacity. Knowledge about the lack of a predecessor to this event was part of the reason for the apparent lack of anticipation and preparedness. Clearly, this event has changed the perception of earthquake/tsunami hazard along the Andaman and Nicobar Islands as well as regions along the southwest coast of India, far removed from the source earthquake. The government of India is embarking on a major programme to study the earthquake processes in the Andaman and Nicobar regions, part of the subduction zone stretching about 1000 km, most of which was affected by the earthquake. These efforts include expansion and modernization of the existing seismic network, continuous and campaign-mode GPS surveys, geological and geophysical investigations and inundation mapping. Research programmes being funded by the DST aims at improved understanding of the seismic sources, their past behavior, rupture characteristics, physical processing related to earthquakes in this subduction zone and style of deformation using geodetic techniques. A network of more than 100 seismological stations operate in India presently, most of them being operated by the India Meteorological Department, the nodal agency for seismological studies. Linking and modernization and addition of more seismic observatories are underway. The station at Port Blair has been upgraded as broadband and a good network of portable stations are now operational. Added to these are the GPS campaign mode surveys that are being done along the entire arc. Establishment of a multiparametric geophysical observatory to monitor physical processes prior to large earthquakes is another experiment in plan. The structure of the Tsunami Warning System being proposed also involves establishment of more tide gauges and pressure sensors at strategic locations. It is expected that the data generated through various research initiatives will provide the necessary scientific basis for the proposed warning system.

    Waukesha Electric Systems has been working in HTS power transformers development program under the auspices of US Government Department of Energy since 1994. This presentation will describe various milestones for this program and program history along with the lessons learned along the way. Our motivations for working on this development program based on man benefits offered by HTS power transformers to power delivery systems will be discussed. Based on various issues encountered during execution of many HTS projects, DOE has set up an independent program review process that is lead by team of experts. This team reviews are integral part of all DOE HTS projects. Success of all projects would be greatly enhanced by identifying critical issues early in the program. Requiring appropriate actions to mitigate the issues before processing further will lead to proactive interrogation and incorporation of expert’s ideas in the project plans. Working of this review process will be also described in this presentation. Waukesha Electric Systems team including: Superpower-Inc, Oak Ridge National Laboratory, University of Houston Center for Superconductivity and Southern California Edison company was awarded a cost share grant by US Government in 2010 for development of a fault current limiting HTS power transformer. This multi year’s program will require design, manufacture, installation, and monitoring of a 28 MVA tree phase transformer installed at Irvine CA. Smart Grid demonstration site. Transformer specifications along with requirements for fault current limiting and site requirement will be discussed. Design and development of various sub systems in support of this program including: HTS conductor performance specification, Dielectric system design approach, Dewar development for containing phase assemblies, cryo-cooling system design approach, etc. will be described. Finally; overall program schedule, critical milestone events, test plans and progress to date will be reported.

  2. College for some to college for all: social background, occupational expectations, and educational expectations over time.

    PubMed

    Goyette, Kimberly A

    2008-06-01

    The educational expectations of 10th-graders have dramatically increased from 1980 to 2002. Their rise is attributable in part to the changing educational composition of students' parents and related to the educational profiles of their expected occupations. Students whose parents have gone to college are more likely to attend college themselves, and students expect occupations that are more prestigious in 2002 than in 1980. The educational requirements of particular occupation categories have risen only slightly. These analyses also reveal that educational expectations in recent cohorts are more loosely linked to social background and occupational plans than they were in 1980. The declining importance of parents' background and the decoupling of educational and occupational plans, in addition to a strong and significant effect of cohort on educational expectations, suggest that the expectation of four-year college attainment is indeed becoming the norm.

  3. Powering Up: Assessing the growing municipal energy resilience building efforts in North America

    NASA Astrophysics Data System (ADS)

    Schimmelfing, Kara

    Energy related shortages and price volatilities can impact all levels of society. With coming fossil fuel depletion related to peak oil, it is expected these shortages and volatilities will increase in frequency, duration, and intensity. Resilience building is a strategy to minimize the effects of these events by modifying systems so they are less impacted and/or recover more quickly from disruptive events. Resilience building is being used, particularly at the municipal scale, to prepare for these coming energy related changes. These municipal efforts have only been in existence for five to ten years, and full implementation is still in progress. Little evaluation has been done of these municipal efforts to date, particularly in North America. Despite this, it is important to begin to assess the effectiveness of these efforts now. As a result, future efforts can be redirected to address weak areas and that lessons learned by vanguard communities can be applied in other communities attempting to build energy resilience in the future. This thesis involved the creation of a hybrid framework to evaluate municipal energy resilience building efforts. The framework drew primarily from planning process and factors identified as important to build resilience in social-ecological systems. It consisted of the following categories to group resilience building efforts: Economy, Resource Systems & Infrastructure, Public Awareness, Social Services, Transportation, Built Environment, and Natural Environment. Within these categories the following process steps should be observed: Context, Goals, Needs, Processes, and Outcomes. This framework was then tested through application to four case-study communities (Bloomington, IN, Hamilton, ON, Oakland, CA, Victoria, BC) currently pursuing energy resilience building efforts in North America. This qualitative research involved document analysis primarily of municipal documents related to energy planning efforts. Supplementary interviews were also conducted to verify the findings from the documents and illuminate anything not captured by them. Once data was collected, categorized and analyzed using the framework, comparisons were made between case-studies. Results showed the framework to be a successful, but time consuming, tool for assessing municipal energy resilience building. Four revisions are recommended for the framework before further research. Analysis of the case study communities' efforts also identified five factors for recommended for other communities attempting energy resilience planning at the municipal scale: consistent support from within the municipality, integration and information sharing, presence of key resources, access to information on energy use, and a two-tier planning process. Ultimately, as this is a preliminary attempt to address a young and growing area of municipal effort, there are many avenues for further research to build on the work of this thesis.

  4. The moderating effect of gender on the relation between expectancies and gambling frequency among college students.

    2015-03-01

    Compared to college females, college males are more likely to report frequent gambling. Research on gambling outcome expectancies has shown that expectations about gambling influence gambling behavior and that endorsement of particular expectancies differs by gender. Knowledge regarding the differential predictive utility of specific gambling expectancies based on gender would help to determine how beliefs about gambling may be fundamentally different for men and women. The present study explored whether gender moderates the relation between gambling expectancy and gambling frequency in a college sample. 421 college students completed an online survey that included questions about their demographics, gambling frequency, and gambling expectancies. Hierarchical regression analyses indicated that gender moderated the relations between the expectancies of social consequences, material gain, and gambling frequency. For females, greater endorsement of social consequences predicted less frequent gambling. For both males and females, greater endorsement of material gain predicted more frequent gambling. The current findings can help inform prevention and intervention efforts by identifying gambling expectations that are differentially related to college student gambling behavior choices.

  5. Temporal expectations and neural amplitude fluctuations in auditory cortex interactively influence perception.

    PubMed

    Herrmann, Björn; Henry, Molly J; Haegens, Saskia; Obleser, Jonas

    2016-01-01

    Alignment of neural oscillations with temporally regular input allows listeners to generate temporal expectations. However, it remains unclear how behavior is governed in the context of temporal variability: What role do temporal expectations play, and how do they interact with the strength of neural oscillatory activity? Here, human participants detected near-threshold targets in temporally variable acoustic sequences. Temporal expectation strength was estimated using an oscillator model and pre-target neural amplitudes in auditory cortex were extracted from magnetoencephalography signals. Temporal expectations modulated target-detection performance, however, only when neural delta-band amplitudes were large. Thus, slow neural oscillations act to gate influences of temporal expectation on perception. Furthermore, slow amplitude fluctuations governed linear and quadratic influences of auditory alpha-band activity on performance. By fusing a model of temporal expectation with neural oscillatory dynamics, the current findings show that human perception in temporally variable contexts relies on complex interactions between multiple neural frequency bands.

  17. Developing expectations regarding the boundaries of expertise.

    PubMed

    Landrum, Asheley R; Mills, Candice M

    2015-01-01

    Three experiments examined elementary school-aged children's and adults' expectations regarding what specialists (i.e., those with narrow domains of expertise) and generalists (i.e., those with broad domains of expertise) are likely to know. Experiment 1 demonstrated developmental differences in the ability to differentiate between generalists and specialists, with younger children believing generalists have more specific trivia knowledge than older children and adults believed. Experiment 2 demonstrated that children and adults expected generalists to have more underlying principles knowledge than specific trivia knowledge about unfamiliar animals. However, they believed that generalists would have more of both types of knowledge than themselves. Finally, Experiment 3 demonstrated that children and adults recognized that underlying principles knowledge can be generalized between topics closely related to the specialists' domains of expertise. However, they did not recognize when this knowledge was generalizable to topics slightly less related, expecting generalists to know only as much as they would. Importantly, this work contributes to the literature by showing how much of and what kinds of knowledge different types of experts are expected to have. In sum, this work provides insight into some of the ways children's notions of expertise change over development. The current research demonstrates that between the ages of 5 and 10, children are developing the ability to recognize how experts' knowledge is likely to be limited. That said, even older children at times struggle to determine the breadth of an experts' knowledge. PMID:25460394

The experimenter then hid the object behind one of…

  20. Robust estimation by expectation maximization algorithm

    NASA Astrophysics Data System (ADS)

    2013-02-01

    A mixture of normal distributions is assumed for the observations of a linear model. The first component of the mixture represents the measurements without gross errors, while each of the remaining components gives the distribution for an outlier. Missing data are introduced to deliver the information as to which observation belongs to which component. The unknown location parameters and the unknown scale parameter of the linear model are estimated by the EM algorithm, which is iteratively applied. The E (expectation) step of the algorithm determines the expected value of the likelihood function given the observations and the current estimate of the unknown parameters, while the M (maximization) step computes new estimates by maximizing the expectation of the likelihood function. In comparison to Huber's M-estimation, the EM algorithm does not only identify outliers by introducing small weights for large residuals but also estimates the outliers. They can be corrected by the parameters of the linear model freed from the distortions by gross errors. Monte Carlo methods with random variates from the normal distribution then give expectations, variances, covariances and confidence regions for functions of the parameters estimated by taking care of the outliers. The method is demonstrated by the analysis of measurements with gross errors of a laser scanner.

    The brain generates a representation of our environment by integrating signals from a common source, but segregating signals from different sources. This fMRI study investigated how the brain arbitrates between perceptual integration and segregation based on top-down congruency expectations and bottom-up stimulus-bound congruency cues. Participants were presented audiovisual movies of phonologically congruent, incongruent or McGurk syllables that can be integrated into an illusory percept (e.g. "ti" percept for visual «ki» with auditory /pi/). They reported the syllable they perceived. Critically, we manipulated participants' top-down congruency expectations by presenting McGurk stimuli embedded in blocks of congruent or incongruent syllables. Behaviorally, participants were more likely to fuse audiovisual signals into an illusory McGurk percept in congruent than incongruent contexts. At the neural level, the left inferior frontal sulcus (lIFS) showed increased activations for bottom-up incongruent relative to congruent inputs. Moreover, lIFS activations were increased for physically identical McGurk stimuli, when participants segregated the audiovisual signals and reported their auditory percept. Critically, this activation increase for perceptual segregation was amplified when participants expected audiovisually incongruent signals based on prior sensory experience. Collectively, our results demonstrate that the lIFS combines top-down prior (in)congruency expectations with bottom-up (in)congruency cues to arbitrate between multisensory integration and segregation.

    The last decade has witnessed a vigorous and sustained research effort on unstructured methods for computational fluid dynamics. Unstructured mesh generators and flow solvers have evolved to the point where they are now in use for design purposes throughout the aerospace industry. In this paper we survey the various mesh types, structured as well as unstructured, and examine their relative strengths and weaknesses. We argue that unstructured methodology does offer the best prospect for the next generation of computational fluid dynamics algorithms.

  6. The Activation of Reward Versus Relief Gambling Outcome Expectancies in Regular Gamblers: Relations to Gambling Motives.

    Gambling outcome expectancies refer to the anticipated outcomes that gamblers expect will occur from gambling (i.e., learned memory associations between gambling cues, behavior, and outcomes). Unlike previous approaches to gambling outcome expectancies that have predominantly focused on the valence of outcome expectancies (positive vs. negative), the present study investigated two specific types of positive gambling outcome expectancies: reward and relief gambling outcome expectancies. Specifically, the primary purpose of the current research was to examine whether gambling prime exposure activates different types of positive gambling outcome expectancies in enhancement- versus coping-motivated gamblers. Fifty adult, community-recruited regular gamblers performed a reaction time (RT) task and completed a self-report expectancy scale, both designed to assess reward and relief gambling outcome expectancies. They also completed the Gambling Motives Questionnaire (Stewart and Zack in Addiction 103:1110-1117 2008) to assess their levels of coping and enhancement motives for gambling. As hypothesized, reward gambling outcome expectancies were more strongly activated by gambling prime exposure than relief outcome expectancies on the RT task for gamblers with high enhancement motives. On the self-report expectancy measure, high enhancement-motivated gamblers endorsed stronger reward gambling outcome expectancies than low enhancement-motivated gamblers, and high coping-motivated gamblers endorsed stronger relief gambling outcome expectancies than low coping-motivated gamblers. Results suggest that automatic activation of reward gambling outcome expectancies is particularly strong for high enhancement-motivated gamblers. Possible reasons for the failure to observe an association between coping gambling motives and automatic relief gambling outcome expectancies are discussed. PMID:24916965

    Report VI presents a comprehensive plan for the management of the Breckinridge Project. For the purpose of this report, the project work is divided into five major project phases: Development, Engineering, Procurement, Construction, and Operations. The results of the Development Phase (Initial Effort) of the project are discussed in Section 1.0. This phase of the project was performed under a Cooperative Agreement with US Department of Energy and has produced 43 volumes of documentation. Fifteen volumes contain information of proprietary nature for patented processes and are therefore classified as Limited Access; however, twenty-eight volumes are not classified and are suitable for public dissemination. This Project Management Plan is a volume of the unclassified documentation. The other twenty-seven volumes contain comprehensive data on technical, financial, and environmental aspects of the project. Each of the four remaining project phases is presented starting with the extensive planning that will be performed and continuing through to the execution and completion of each phase. The major roles of the Operator, Ashland Synthetic Fuels, Inc. (ASFI), and the Managing Contractor are defined. Although a contract has not yet been executed with a Managing Contractor, the procedures, controls, organization and management philosophy of Bechtel Petroleum, Inc., are presented in this report as being representative of those used by contractors in the business of performing the engineering, procurement, and construction of projects of this size and complexity. The organizational structures of the Operator and the Managing Contractor are described, with designation of key project team personnel by job description and organization charts. Provisions for cost, schedule, and material control are described.

    Boys with Attention Deficit Hyperactivity Disorder (ADHD, N = 50), Specific Learning Disorder (LD, N = 45), combined Specific Learning Disorder and ADHD (LD/ADHD, N = 25), and controls (N = 51) completed effortful and automatic information processing tasks based on Treisman and Gelade's (1980) "information integration theory". ADHD and LD/ADHD subjects did not differ from controls at baseline or under feedback and reward conditions, suggesting that they were investing similar levels of mental effort in the tasks. The LD group had a superior performance in the effortful task and an inferior performance in the automatic task compared with the other groups at baseline. The data suggest a potential method of distinguishing primary LD from learning difficulties that occur secondary to ADHD. PMID:10188710

    Relationship satisfaction and stability are two commonly studied outcomes in marriage and family research. Majority of studies address socio demographic variability and differences across union type in these outcomes. We extend this literature by addressing how the amount of effort one puts into their relationship is associated with stability and satisfaction. Specifically, we focus on how effort impacts these measures of quality in four union types: premarital cohabitation, first marriage, post-divorce cohabitation, and second marriage following divorce. Furthermore, we make union type comparisons in the strength of effort's association with satisfaction and stability. Using data from 8,006 respondents in the Relationship Evaluation Survey, our results show that effort was strongly and positively associated with satisfaction and stability in all four unions. Although effort is more strongly associated with satisfaction in first marriage than cohabiting relationships, no union type differences in the role of effort on stability were observed. Clinical and research implications of these findings are discussed. PMID:24320175

    After successful acquisition in August of reflected ruby laser pulses from the Apollo 11 laser ranging retro-reflector (LRRR) with the telescopes at the Lick and McDonald observatories, repeated measurements of the round-trip travel time of light have been made from the McDonald Observatory in September with an equivalent range precision of +/-2.5 meters. These acquisition period observations demonstrated the performance of the LRRR through lunar night and during sunlit conditions on the moon. Instrumentation activated at the McDonald Observatory in October has yielded a precision of +/-0.3 meter, and improvement to +/-0.15 meter is expected shortly. Continued monitoring of the changes in the earth-moon distance as measured by the round-trip travel time of light from suitably distributed earth stations is expected to contribute to our knowledge of the earth-moon system.

  14. The maximum life expectancy for a micro-fabricated diaphragm

    Micro-fabricated diaphragms can be used to provide pumping action in microvalve and microfluidic applications. The functionality of the microdiaphragm in a wirelessly actuated micropump plays a major role in low-powered device actuation. In developing micropumps and their components, it is becoming an increasing trend to predict the performance before the prototype is fabricated. Because performance prediction allows for an accurate estimation of yield and lifetime, in addition to developing better understanding of the device while taking into account the details of the device structure and second order effects. Hence avoid potential pitfalls in the device operation in a practical environment. The goal of this research is to determine via FEA the life expectancy for a corrugated circular diaphragm made out of an aluminum alloy. The geometry of the diaphragm is given below being generated within SolidWorks 2010, all the calculations were made using Ansys 13TM . The sound design of a micropump is heavily depending on the lifetime expectancy of the working part of the device which is the diaphragm. This will be subjected on cyclic loading and the fatigue will limit the life of this part. Once the diaphragm is breaking, the micropump is no more able to fulfill its scope. Any micropump manufacturer will then be very concerned on the life expectancy from the fatigue point of view of the diaphragms. The diaphragm circular and corrugated and made of Al alloy, showed a very good behavior from the fatigue point of view, the maximum life expectancy being 1.9 years of continuous functioning with 100 cycles per second. This work showed an simple and forward application of FEA analysis methods in order to estimate the fatigue behavior of corrugated circular microdiaphragms.

    The road traffic crash burden is significant in Brazil; calculating years of life lost and life expectancy reduction quantifies the burden of road traffic deaths to enable prioritization of this issue. Years of life lost and reduction in life expectancy were calculated using 2008 population/crash data from Brazil's ministries of health and transport. The potential for reduction in crash mortality was calculated for hypothetical scenarios reducing death rates to those of the best-performing region and age category. In Brazil, road traffic deaths reduce the at-birth life expectancy by 0.8 years for males and by 0.2 years for females. Many years of life lost for men and woman could be averted-270,733 and 123,986, respectively-if all rates matched those of the lowest-risk region and age category. This study further characterizes the burden of motor vehicle deaths in Brazil and quantifies the potential health benefits of policies/interventions that reduce road traffic death rates to those of the best-performing subpopulations.

    1999-02-01

    Collective efficacy is an important determinant of the motivation of individuals within groups, with increases in collective efficacy producing more effort in a task and greater persistence when faced with failure. To test hypotheses concerning the impact of collective efficacy on effort and persistence, participants (n = 22) were assigned to triads (consisting of the participant and two confederates) and performed three time trials on cycle ergometers. After trial 1, the participants were assigned to either a high or low collective efficacy condition, receiving appropriate bogus performance feedback. All groups received failure feedback after trial 2. Effort was assessed by performance time and maximum heart rate (HRmax) achieved during performance. A 2 (collective efficacy condition) x 3 (trials) analysis of variance with repeated measures on trials revealed significant interaction effects for both performance time and HRmax. Fisher's least significant difference post-hoc tests indicated that, following efficacy manipulation, groups low in collective efficacy significantly reduced both their performance time and HRmax, whereas groups high in collective efficacy maintained performance and HRmax. However, predictions concerning the impact of failure on persistence were not supported. Our results provide partial support for the role of collective efficacy in team sports. PMID:10069272

    Apathy is a common but poorly understood condition with a wide societal impact observed in several brain disorders as well as, to some extent, in the normal population. Hence the need for better characterization of the underlying mechanisms. The processes by which individuals decide to attribute physical effort to obtain rewards might be particularly relevant to relate to apathy traits. Here, we designed two paradigms to assess individual differences in physical effort production and effort-based decision-making and their relation to apathy in healthy people. Apathy scores were measured using a modified version of the Lille Apathy Rating Scale, suitable for use in a non-clinical population. In the first study, apathy scores were correlated with the degree to which stake (reward on offer) and difficulty level impacts on physical effort production. Individuals with relatively high apathy traits showed an increased modulation of effort while more motivated individuals generally exerted greater force across different levels of stake. To clarify the underlying mechanisms for this behavior, we designed a second task that allows independent titration of stake and effort levels for which subjects are willing to engage in an effortful response to obtain a reward. Our results suggest that apathy traits in the normal population are related to the way reward subjectively affects the estimation of effort costs, and more particularly manifest as decreased willingness to exert effort when rewards are small, or below threshold. The tasks we introduce here may provide useful tools to further investigate apathy in clinical populations. PMID:24747776

    Effort and reward jointly shape many human decisions. Errors in predicting the required effort needed for a task can lead to suboptimal behavior. Here, we show that effort estimations can be biased when retrospectively reestimated following receipt of a rewarding outcome. These biases depend on the contingency between reward and task difficulty and are stronger for highly contingent rewards. Strikingly, the observed pattern accords with predictions from Bayesian cue integration, indicating humans deploy an adaptive and rational strategy to deal with inconsistencies between the efforts they expend and the ensuing rewards.

    Objectives The dual-task paradigm has been widely used to measure listening effort. The primary objectives of the study were to (1) investigate the effect of hearing aid amplification and a hearing aid directional technology on listening effort measured by a complicated, more real world dual-task paradigm, and (2) compare the results obtained with this paradigm to a simpler laboratory-style dual-task paradigm. Design The listening effort of adults with hearing impairment was measured using two dual-task paradigms, wherein participants performed a speech recognition task simultaneously with either a driving task in a simulator or a visual reaction-time task in a sound-treated booth. The speech materials and road noises for the speech recognition task were recorded in a van traveling on the highway in three hearing aid conditions: unaided, aided with omni directional processing (OMNI), and aided with directional processing (DIR). The change in the driving task or the visual reaction-time task performance across the conditions quantified the change in listening effort. Results Compared to the driving-only condition, driving performance declined significantly with the addition of the speech recognition task. Although the speech recognition score was higher in the OMNI and DIR conditions than in the unaided condition, driving performance was similar across these three conditions, suggesting that listening effort was not affected by amplification and directional processing. Results from the simple dual-task paradigm showed a similar trend: hearing aid technologies improved speech recognition performance, but did not affect performance in the visual reaction-time task (i.e., reduce listening effort). The correlation between listening effort measured using the driving paradigm and the visual reaction-time task paradigm was significant. The finding showing that our older (56 to 85 years old) participants’ better speech recognition performance did not result in reduced listening effort was not consistent with literature that evaluated younger (approximately 20 years old), normal hearing adults. Because of this, a follow-up study was conducted. In the follow-up study, the visual reaction-time dual-task experiment using the same speech materials and road noises was repeated on younger adults with normal hearing. Contrary to findings with older participants, the results indicated that the directional technology significantly improved performance in both speech recognition and visual reaction-time tasks. Conclusions Adding a speech listening task to driving undermined driving performance. Hearing aid technologies significantly improved speech recognition while driving, but did not significantly reduce listening effort. Listening effort measured by dual-task experiments using a simulated real-world driving task and a conventional laboratory-style task was generally consistent. For a given listening environment, the benefit of hearing aid technologies on listening effort measured from younger adults with normal hearing may not be fully translated to older listeners with hearing impairment.

    2013-01-01

    What are the developmental origins of our concept of animal? There has long been controversy concerning this question. At issue is whether biological reasoning develops from earlier forms of reasoning, such as physical and psychological reasoning, or whether from a young age children endow animals with biological properties. Here we demonstrate that 8-mo-old infants already expect novel objects they identify as animals to have insides. Infants detected a violation when an object that was self-propelled and agentive (but not an object that lacked one or both of these properties) was revealed to be hollow. Infants also detected a violation when an object that was self-propelled and furry (but not an object that lacked one or both of these properties) either was shown to be hollow or rattled (when shaken) as although mostly hollow. Young infants’ expectations about animals’ insides may serve as a foundation for the development of more advanced biological knowledge. PMID:24003134

    Three hundred seven undergraduate students enrolled in Introductory Astronomy were surveyed at the beginning of class to determine their expectations for course content. The course serves as a survey of astronomy for non-science majors and is a distribution course for general education core requirements. The course has no prerequisites, meets three times each week for 50 minutes, and represents three semester credit hours. The university catalog describes the course with the title "PHYSICS 101 - Mysteries of the Sky" and the official course description is: a survey of the struggle to understand the Universe and our place therein. The structure, growth, methods, and limitations of science will be illustrated using the development of astronomy as a vehicle. Present day views of the Universe are presented. Two questions were asked as open response items: What made you decide to take this course? and What do you expect to learn in this course? The reasons that students cited to take the course, in order of frequency, were: interested in astronomy, interesting or fun sounding course, required general education fulfillment, recommendation by peer. Secondary reasons cited were required for major or minor, general interest in science, and was available in the schedule. Tertiary reasons listed were recommendation by advisor or orientation leader, inflate grade point average, and heard good things about the teacher. The students' expectations about what they would learn in the course were numerous. The most common objects listed, in order of frequency, were: stars, constellations, planets, galaxies, black holes, solar system, comets, galaxies, asteroids, moon, and Sun. More interesting were the aspects not specifically related to astronomy. These were weather, atmosphere, UFOs and the unexplained, generally things in the sky. A mid-course survey suggests that students expected to learn more constellations and that the topics would be less in-depth.

  7. Investigating expectation effects using multiple physiological measures

    2015-01-01

    The study aimed at experimentally investigating whether the human body can anticipate future events under improved methodological conditions. Previous studies have reported contradictory results for the phenomenon typically called presentiment. If the positive findings are accurate, they call into doubt our views about human perception, and if they are inaccurate, a plausible conventional explanation might be based on the experimental design of the previous studies, in which expectation due to item sequences was misinterpreted as presentiment. To address these points, we opted to collect several physiological variables, to test different randomization types and to manipulate subjective significance individually. For the latter, we combined a mock crime scenario, in which participants had to steal specific items, with a concealed information test (CIT), in which the participants had to conceal their knowledge when interrogated about items they had stolen or not stolen. We measured electrodermal activity, respiration, finger pulse, heart rate (HR), and reaction times. The participants (n = 154) were assigned randomly to four different groups. Items presented in the CIT were either drawn with replacement (full) or without replacement (pseudo) and were either presented category-wise (cat) or regardless of categories (nocat). To understand how these item sequences influence expectation and modulate physiological reactions, we compared the groups with respect to effect sizes for stolen vs. not stolen items. Group pseudo_cat yielded the highest effect sizes, and pseudo_nocat yielded the lowest. We could not find any evidence of presentiment but did find evidence of physiological correlates of expectation. Due to the design differing fundamentally from previous studies, these findings do not allow for conclusions on the question whether the expectation bias is being confounded with presentiment.

    1994-05-27

    On May 12, (1994) a subcommittee of the House Education and Labor Committee voted 16-11 in support of retaining abortion coverage in the President's proposed health care plan. With its vote, the Labor/Management Relations subcommittee rejected an amendment by Representative Ron Klink (D-PA), which would have allowed insurers to cover abortions only in cases of forcible rape or incest, or life endangerment. Two Republican Representatives joined 14 Democrats voting against the amendment, while 3 Democratic Representatives were among the 11 people supporting the Klink amendment. The subcommittee also defeated an amendment introduced by Representative Dick Armey (R-TX), which would have prohibited any language in a health care reform bill from overruling constitutional state laws restricting abortion. 14 subcommittee members voted against the Armey amendment; 11 voted in favor. The subcommittee is not expected to act on a final health care measure before the Memorial Day recess. In related news, a Veterans' Affairs House subcommittee voted 11-8 on May 11 to prohibit the performance of abortions at Department of Veterans' Affairs Hospitals or the coverage of abortion services by VA funds. The amendment was introduced in the Hospitals and Health Care subcommittee by Representative Chris Smith (R-NJ). Neither subcommittee action represents a final decision on abortion coverage in health care reform and none of the 5 Congressional committees considering health reform is expected to finalize their proposals before the Memorial Day recess. The Senate Labor and Human Resources Committee and the House Ways and Means Committee started work on health care reform on May 18. The Senate Finance Committee has only been meeting privately thus far, while neither the full House Education and Labor Committee nor the House Energy and Commerce Committee has met. PMID:12319328

    The principal aim of this study is to determine the impact of ISO/TS16949 efforts on total quality management (TQM) and the ISO/TS16949 efforts relationship in Malaysian automotive industry. A survey method was employed to collect data using English version for Malaysian respondents. Exploratory factor analysis and reliability analysis empirically verified and validated the underlying items of TQM, ISO/TS16949 and organizational performance. Structural equation modeling was employed to test the proposed model. Data analysis revealed that TQM implementations have a strong and positive impact on organizational performance through direct relationship as well as through a mediating role of ISO/TS16949 efforts. From the research findings, it is viable to recommend that ISO/TS16949 should be incorporated with philosophy and methods of TQM to achieve better performance. This study proved to be valuable to academic researchers as well as automotive practitioners. It systematically analyzes the mediating effect of ISO/TS16949 efforts on TQM and organizational performance relationship.

    DOE-RL has set clear expectations for a cost-effective approach for achieving compliance with the Nuclear Safety Management requirements (10 CFR 830, Nuclear Safety Rule) which will ensure long-term benefit to Hanford. To facilitate implementation of these expectations, tools were developed to streamline and standardize safety analysis and safety document development resulting in a shorter and more predictable DOE approval cycle. A Hanford Safety Analysis and Risk Assessment Handbook (SARAH) was issued to standardized methodologies for development of safety analyses. A Microsoft Excel spreadsheet (RADIDOSE) was issued for the evaluation of radiological consequences for accident scenarios often postulated for Hanford. A standard Site Documented Safety Analysis (DSA) detailing the safety management programs was issued for use as a means of compliance with a majority of 3009 Standard chapters. An in-process review was developed between DOE and the Contractor to facilitate DOE approval and provide early course correction. As a result of setting expectations and providing safety analysis tools, the four Hanford Site waste management nuclear facilities were able to integrate into one Master Waste Management Documented Safety Analysis (WM-DSA).

    Although integration involves a process of mutual accommodation, the role of majority groups is often downplayed to passive tolerance, leaving immigrants with the sole responsibility for active integration. However, we show that common group identity can actively involve majority members in this process across five studies. Study 1 showed that common identity positively predicted support of integration efforts; Studies 2 and 3 extended these findings, showing that it also predicted real behavior such as monetary donations and volunteering. A decrease in modern racism mediated the relations across these studies, and Studies 4 and 5 further demonstrated that it indeed mediated these effects over and above acculturation expectations and color-blindness, which somewhat compromised integration efforts. Moreover, the last two studies also demonstrated that common, but not dual, groups motivated integration efforts. Common identity appears crucial for securing majorities' altruistic efforts to integrate immigrants and, thus, for achieving functional multiculturalism. PMID:26276500

    When confronted with food, restrained eaters have to inhibit the pursuit of the short-term goal of enjoying their food for the sake of the long-term goal of controlling their weight. Thus, restrained eating creates a self-control situation. In the present study we investigated the initiation of effortful self-control by food cues in accordance with the level of restrained eating. We expected that a preceding act of self-control would moderate the association between restrained eating and effortful self-control initiated by food cues. Participants (N=111) were randomly assigned to a task requiring self-control or a task not requiring self-control. Subsequently, participants were exposed to palatable food, and effortful self-control was measured via heart rate variability (HRV). Restrained eating was associated with enhanced HRV during food exposure after exercising self-control but not after not exercising self-control. The results indicate that maintaining dieting goals results in food cues initiating effortful self-control after a preceding act of self-control. We suggest considering the effect of acts of self-control when modeling the initial steps on the path from food cues to unsuccessful restrained eating. PMID:26500202

    The purpose of this paper is to review the literature to characterize infiltration rates from landfill liners to support groundwater modeling efforts. The focus of this investigation was on collecting studies that describe the performance of liners 'as installed' or 'as operated'. This document reviews the state of the science and practice on the infiltration rate through compacted clay liner (CCL) for 149 sites and geosynthetic clay liner (GCL) for 1 site. In addition, it reviews the leakage rate through geomembrane (GM) liners and composite liners for 259 sites. For compacted clay liners (CCL), there was limited information on infiltration rates (i.e., only 9 sites reported infiltration rates.), thus, it was difficult to develop a national distribution. The field hydraulic conductivities for natural clay liners range from 1 x 10(-9) cm s(-1) to 1 x 10(-4) cm s(-1), with an average of 6.5 x 10(-8) cm s(-1). There was limited information on geosynthetic clay liner. For composite lined and geomembrane systems, the leak detection system flow rates were utilized. The average monthly flow rate for composite liners ranged from 0-32 lphd for geomembrane and GCL systems to 0 to 1410 lphd for geomembrane and CCL systems. The increased infiltration for the geomembrane and CCL system may be attributed to consolidation water from the clay. PMID:15327165

    The effects of sleep deprivation on cognitive performance psychological variables related to cognitive performance were studied in 44 college students. Participants completed the Watson-Glaser Critical Thinking Appraisal after either 24 hours of sleep deprivation or approximately 8 hours of sleep. After completing the cognitive task, the participants completed 2 questionnaires, one assessing self-reported effort, concentration, and estimated performance, the other assessing off-task cognitions. As expected, sleep-deprived participants performed significantly worse than the nondeprived participants on the cognitive task. However, the sleep-deprived participants rated their concentration and effort higher than the nondeprived participants did. In addition, the sleep-deprived participants rated their estimated performance significantly higher than the nondeprived participants did. The findings indicate that college students are not aware of the extent to which sleep deprivation negatively affects their ability to complete cognitive tasks. PMID:9394089
