literature research, HPE is defined as the degree to which leaders succeed in expressing ambitious expectations to their employees’ achievement of given performance criteria, and it is analyzed how leadership behavior affects employee-perceived HPE. This study applies a large-scale leadership field...... experiment with 3,730 employees nested in 471 organizations and finds that transformational leadership training as well as transactional and combined training of the leaders significantly increased employees’ HPE relative to a control group. Furthermore, transformational leadership and the use of pecuniary...... rewards seem to be important mechanisms. This implies that public leaders can actually affect HPE through their leadership and thus potentially organizational performance as well....

The pumped divertor to be installed in JET should allow a control of the particles and of the impurities. The new hardware required into the vacuum vessel leads to a reduction of the plasma cross section. While a plasma current of 6 MA should still be possible, this will affect the confinement of the plasma. The JET performances in the New Configuration are estimated from the critical electron temperature gradient model by using a 1-D transport code. It has been shown in the past that this model gives a rather satisfactory description of the JET discharges. However it does not address the particle transport and density profiles have to be imposed. By comparison with numerical simulations of the present JET configuration, it is shown that the reduction in plasma size should be more than balanced by the lower impurity concentration expected to result from the divertor. In terms of thermonuclear Q th , a doubling is found relatively to the expectations in the present configuration (≅ .9 against .45). On the other hand Q th should be lowered to .3 if the impurity control is inefficient. In this case as presently observed in JET it is expected that no steady state will be achieved. (author)

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

This research explored the relations between the predictability of musical structure, expressive timing in performance, and listeners' perceived musical tension. Studies analyzing the influence of expressive timing on listeners' affective responses have been constrained by the fact that, in most pieces, the notated durations limit performers' interpretive freedom. To circumvent this issue, we focused on the unmeasured prelude, a semi-improvisatory genre without notated durations. In Experiment 1, 12 professional harpsichordists recorded an unmeasured prelude on a harpsichord equipped with a MIDI console. Melodic expectation was assessed using a probabilistic model (IDyOM [Information Dynamics of Music]) whose expectations have been previously shown to match closely those of human listeners. Performance timing information was extracted from the MIDI data using a score-performance matching algorithm. Time-series analyses showed that, in a piece with unspecified note durations, the predictability of melodic structure measurably influenced tempo fluctuations in performance. In Experiment 2, another 10 harpsichordists, 20 nonharpsichordist musicians, and 20 nonmusicians listened to the recordings from Experiment 1 and rated the perceived tension continuously. Granger causality analyses were conducted to investigate predictive relations among melodic expectation, expressive timing, and perceived tension. Although melodic expectation, as modeled by IDyOM, modestly predicted perceived tension for all participant groups, neither of its components, information content or entropy, was Granger causal. In contrast, expressive timing was a strong predictor and was Granger causal. However, because melodic expectation was also predictive of expressive timing, our results outline a complete chain of influence from predictability of melodic structure via expressive performance timing to perceived musical tension.

Mutual Expectations of Mothers of Hospitalized Children and Pediatric Nurses Who Provided Care: Qualitative Study.

Science.gov (United States)

Konuk Şener, Dilek; Karaca, Aysel

This study attempted to identify the mutual expectations of mothers whose children were hospitalized in the pediatric department of a university hospital and nurses who provided care. A descriptive phenomenological design has been used in this study. Data were obtained through tape-recorded semi-structured interviews. This study was conducted at a pediatric clinic, at a university hospital in a small city in Turkey. Participants comprised five nurses working in the children's clinic and 24 mothers who accompanied their children to the hospital. The six major themes that emerged were mothers' feelings and thoughts about the hospital experience, mothers' expectations for attention and support during hospitalization, mothers' expectations for invasive procedures, issues regarding physical comfort and hospital infrastructure, nurses' feelings and thoughts about working in the pediatric clinic, and nurses' expectations of the mothers. Mothers expected nurses to provide physical support including medication administration, and installing/applying IV and nebulizer treatments; and emotional support in terms of having a friendly, rather than critical attitude, and being approachable and receptive of mothers' questions and anxieties. Nurses stated that they were aware of these expectations but needed mothers to be understanding and tolerant, considering their difficult working conditions. Children's hospitalization is a stressful experience for parents. Open and therapeutic communication and relationships between parents and nurses contribute to improving the quality of care provided to children and their families. Copyright © 2017 Elsevier Inc.

The CMS experiment can contribute significantly to the measurement of the CP violation asymmetries. A recent evaluation of the expected precision on the CP violation parameter sin 2 beta in the channel B /sub d//sup 0/ to J/ psi $9 K/sub s//sup 0/ has been performed using a simulation of the CMS tracker including full pattern recognition. CMS has also studied the possibility to observe CP violation in the decay channel B/sub s//sup 0/ to J/ psi phi . The $9 results of these studies are reviewed. (7 refs).

Engaging service providers in improving industry performance

International Nuclear Information System (INIS)

Oberth, R.

2012-01-01

Effective task leadership is the key to achieving results in the nuclear industry and in most other industries. One of the themes of this conference is to discuss how the nuclear industry can undertake Issue-Identification and Definition as a means of 'identifying what needs attention' and then 'defining what needs to be done to make that happen'. I will explore this theme from the perspective of the 'Service Provider' - which by the definition of this conference includes everyone not within an operating utility - meaning 'those involved in everything from inspection and repair to research and plant architecture' - basically the member companies of my association, OCI. Our members take the definition of the roles and responsibilities of the 'Service Provider' community very seriously. In the context of this discussion a key utility function is the early definition of requirements and expectations of Service Providers in supplying to these requirements. Let's explore for a moment the Service Provider role and perspective. Service Providers are by nature pro-active - they seek ways to engage with utilities (and tier one vendors) to solve problems and achieve good outcomes. They come to industry conferences like this one to learn about upcoming utility programs and supply opportunities and how they can improve performance. Service Providers particularly want to hear senior utility people comment on emerging issues even those at the very early identification stage. Some Clarification of Roles is in Order - as that is the focus of this conference: 'Issue-Identification and Definition'. 'Issue-Identification' is the utility's job - it is the utility's role to identify as early as possible 'what needs attention and what their needs and expectations are'. This takes place before service provider engagement. 'Issue-Definition' is more challenging. It means 'determining and prioritizing what needs to be done to deal with the situation at hand'. This typically involves

Some researchers think that patients with higher expectations for CAM therapies experience better outcomes and that enthusiastic providers can enhance treatment outcomes. This is in contrast to evidence suggesting conventional medical providers often reorient patient expectations to better match what providers believe to be realistic. However, there is a paucity of research on CAM providers' views of their patients' expectations regarding CAM therapy and the role of these expectations in patient outcomes. To better understand how CAM providers view and respond to their patients' expectations of a particular therapy, we conducted 32 semi-structured, qualitative interviews with acupuncturists, chiropractors, massage therapists and yoga instructors identified through convenience sampling. Interviews were recorded, transcribed and analyzed thematically using Atlas ti version 6.1. CAM providers reported that they attempt to ensure that their patients' expectations are realistic. Providers indicated they manage their patients' expectations in a number of domains- roles and responsibilities of providers and patients, treatment outcomes, timeframe for improvement, and treatment experience. Providers reported that patients' expectations change over time and that they need to continually manage these expectations to enhance patient engagement and satisfaction with treatment. Providers of four types of CAM therapies viewed patients' expectations as an important component of their experiences with CAM therapy and indicated that they try to align patient expectations with reality. These findings suggest that CAM providers are similar in this respect to conventional medical providers.

Factors affecting the performance of maternal health care providers in Armenia

2004-06-01

Full Text Available Abstract Background Over the last five years, international development organizations began to modify and adapt the conventional Performance Improvement Model for use in low-resource settings. This model outlines the five key factors believed to influence performance outcomes: job expectations, performance feedback, environment and tools, motivation and incentives, and knowledge and skills. Each of these factors should be supplied by the organization in which the provider works, and thus, organizational support is considered as an overarching element for analysis. Little research, domestically or internationally, has been conducted on the actual effects of each of the factors on performance outcomes and most PI practitioners assume that all the factors are needed in order for performance to improve. This study presents a unique exploration of how the factors, individually as well as in combination, affect the performance of primary reproductive health providers (nurse-midwives in two regions of Armenia. Methods Two hundred and eighty-five nurses and midwives were observed conducting real or simulated antenatal and postpartum/neonatal care services and interviewed about the presence or absence of the performance factors within their work environment. Results were analyzed to compare average performance with the existence or absence of the factors; then, multiple regression analysis was conducted with the merged datasets to obtain the best models of "predictors" of performance within each clinical service. Results Baseline results revealed that performance was sub-standard in several areas and several performance factors were deficient or nonexistent. The multivariate analysis showed that (a training in the use of the clinic tools; and (b receiving recognition from the employer or the client/community, are factors strongly associated with performance, followed by (c receiving performance feedback in postpartum care.

Expected performance of the upgrade ATLAS experiment for HL-LHC

CERN Document Server

Liu, Peilian; The ATLAS collaboration

2018-01-01

The Large Hadron Collider (LHC) has been successfully delivering proton-proton collision data at the unprecedented center of mass energy of 13 TeV. An upgrade is planned to increase the instantaneous luminosity delivered by the LHC in what is called the HL-LHC, aiming to deliver a total of up 3000/fb to 4000/fb of data per experiment. To cope with the expected data-taking conditions ATLAS is planning major upgrades of the detector. It is now a critical time for these upgrade projects and during the last year and a half, six Technical Design Reports (TDR) were produced by the ATLAS Collaboration. In these TDRs the physics motivation and benefits of such upgrades are discussed together with details on the upgrade project itself. In this contribution we review the expected performance of the upgraded ATLAS detector and the expected reach for physics measurements as well as the discovery potential for new physics that is expected by the end of the HL-LHC data-taking. The performance of object reconstruction under...

Utility Expectations for Human Performance and Safety Culture in the Supplier Community

International Nuclear Information System (INIS)

Clewett, L. K.

2016-01-01

Canadian NPPs, like many others around the world, make use of suppliers for the design and execution of major projects, and to support on-going inspection and maintenance activities. The work performed by suppliers today represents a significant portion of the work performed at utility NPPs, and, at times, can even exceed the work performed by utility staff. It is imperative for both the utility and the supplier work forces to work in collaboration to ensure that the probability of consequential errors impacting plant safety or contributing to broader enterprise risk is kept very low. An important element for keeping the risk low is for utilities to work with their suppliers to develop a high degree of confidence that the supplier workforce is performing to the same standards of human performance and safety culture as its own staff. This paper will provide a senior utility executive’s expectations and perspective on achieving excellence in supplier human performance and safety culture. (author)

Performance Measurement, Expectancy and Agency Theory: An Experimental Study

OpenAIRE

Randolph Sloof; Mirjam van Praag

2007-01-01

Theoretical analyses of (optimal) performance measures are typically performed within the realm of the linear agency model. An important implication of this model is that, for a given compensation scheme, the agent's optimal effort choice is unrelated to the amount of noise in the performance measure. In contrast, expectancy theory as developed by psychologists predicts that effort levels are increasing in the signal-to-noise ratio. We conduct a real effort laboratory experiment to assess the...

Tucker, Joan S; Stucky, Brian D; Edelen, Maria Orlando; Shadel, William G; Klein, David J

2018-05-21

The U.S. Public Health Service Clinical Practice Guideline on treating tobacco use and dependence recommends providing advice to quit to every tobacco user seen in a healthcare setting. However, the mechanism through which counseling encourages patients to quit has not been adequately studied. This study tests whether the association between receiving healthcare provider counseling and desire to quit is accounted for by negative health and psychosocial outcome expectancies of smoking. Data were collected online from 721 adult smokers who had seen a healthcare provider in the past 12 months. Associations between counseling to quit, negative outcome expectancies of smoking, and desire to quit were tested, as well as whether outcome expectancies and desire to quit differed by type of counseling (counseling only vs. counseling plus assistance) and level of smoking. Bivariate associations indicated a stronger desire to quit among patients receiving counseling, particularly when it included healthcare provider assistance to quit. SEM results indicated that the association between counseling and desire to quit was fully accounted for by patients' negative health and psychosocial outcome expectancies for smoking. These associations were found across levels of smoking in the case of health expectancies, but were limited to moderate and heavy smokers in the case of psychosocial expectancies. Results suggest that the time devoted to counseling patients about smoking should include providing some assistance to quit, such as recommending a product, prescription or program. Regardless of smoking level, this counseling should incorporate techniques to elicit patients' negative health and psychosocial expectancies of smoking. Copyright © 2018. Published by Elsevier Ltd.

A comparison of the efficiency of health systems in providing life expectancy

The role of the national health systems is to provide health for their citizens but each country achieves it up to a different degree. The health systems are heterogeneous not only in their efficiency but in their funding, organization and management too. As it is difficult to measure...... their efficiency in absolute terms, the countries can be compared with each other. The relative efficiency of health systems can be measured by the life expectancy that they provide by taking education level and their funding structure into account.

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

Science.gov (United States)

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. Copyright © 2015. Published by Elsevier B.V.

2015-10-01

Full Text Available The present study aims to investigate the determinants of satisfaction and the resulting continuance intention use in e-learning context. The constructs of decomposed expectancy disconfirmation theory (DEDT are evaluated from the perspective of users of a virtual learning environment (VLE in relation to expectations and perceived performance. An online survey collected responses from 197 students of a public management course in distance mode. Structural equation modeling was operationalized by the method of partial least squares in Smart PLS software. The results showed that there is a relationship between quality, usability, value and value disconfirmation with satisfaction. Likewise, satisfaction proved to be decisive for the continuance intention use. However, there were no significant relationships between quality disconfirmation and usability disconfirmation with satisfaction. Based on the results, is discussed the theoretical and practical implications of the structural model found by the search.

1989-01-01

A balloon experiment, GRATIS, is being constructed which will perform the first arcmin imaging of cosmic sources in the 30 - 200 keV energy band. Observations conducted with GRATIS can provide data relevant to several key problems in high energy astrophysics, including the physical processes responsible for the high energy tail observed in the soft gamma-ray spectra of clusters of galaxies and the origin of both the diffuse and point-source components of the gamma-ray emission from the Galactic Center. This paper discusses the scientific motivations in detail, outlines the experiment, discusses several aspects of the design and construction of hardware components, gives an overview of the stabilized platform, and shows the expected performance and sensitivity. 16 refs

Expectancy of an open-book test decreases performance on a delayed closed-book test.

Science.gov (United States)

Agarwal, Pooja K; Roediger, Henry L

2011-11-01

Two experiments examined the influence of practice with, and the expectancy of, open-book tests (students viewed studied material while taking the test) versus closed-book tests (students completed the test without viewing the studied material) on delayed retention and transfer. Using GRE materials specifically designed for open-book testing, participants studied passages and then took initial open- or closed-book tests. Open-book testing led to better initial performance than closed-book testing, but on a delayed criterial (closed-book) test both types of testing produced similar retention after a two-day delay in Experiment 1. In Experiment 2 participants were informed in advance about the type of delayed criterial test to expect (open- or closed-book). Expecting an open-book test (relative to a closed-book test) decreased participants' time spent studying and their delayed test performance on closed-book comprehension and transfer tests, demonstrating that test expectancy can influence long-term learning. Expectancy of open-book tests may impair long-term retention and transfer compared to closed-book tests, despite superior initial performance on open-book tests and students' preference for open-book tests.

This paper describes the results of an ITiCSE working group convened in 2013 to review and revisit the influential ITiCSE 2001 McCracken working group that reported [18] on novice programmers' ability to solve a specified programming problem. Like that study, the one described here asked students...... to implement a simple program. Unlike the original study, students' in this study were given significant scaffolding for their efforts, including a test harness. Their knowledge of programming concepts was also assessed via a standard language-neutral survey. One of the significant findings of the original...... working group was that students were less successful at the programming task than their teachers expected, so in this study teachers' expectations were explicitly gathered and matched with students' performance. This study found a significant correlation between students' performance in the practical task...

Unfinished tasks foster rumination and impair sleeping - particularly if leaders have high performance expectations.

Science.gov (United States)

Syrek, Christine J; Antoni, Conny H

2014-10-01

This study examines the relationship between time pressure and unfinished tasks as work stressors on employee well-being. Relatively little is known about the effect of unfinished tasks on well-being. Specifically, excluding the impact of time pressure, we examined whether the feeling of not having finished the week's tasks fosters perseverative cognitions and impairs sleep. Additionally, we proposed that leader performance expectations moderate these relationships. In more detail, we expected the detrimental effect of unfinished tasks on both rumination and sleep would be enhanced if leader expectations were perceived to be high. In total, 89 employees filled out online diary surveys both before and after the weekend over a 5-week period. Multilevel growth modeling revealed that time pressure and unfinished tasks impacted rumination and sleep on the weekend. Further, our results supported our hypothesis that unfinished tasks explain unique variance in the dependent variables above and beyond the influence of time pressure. Moreover, we found the relationship between unfinished tasks and both rumination and sleep was moderated by leader performance expectations. Our results emphasize the importance of unfinished tasks as a stressor and highlight that leadership, specifically in the form of performance expectations, contributes significantly to the strength of this relationship.

Science.gov (United States)

Meyer, Eric C; Lynn, Steven Jay

2011-07-01

This study examined the relative impact of hypnotic inductions and several other variables on hypnotic and nonhypnotic responsiveness to imaginative suggestions. The authors examined how imaginative suggestibility, response expectancies, motivation to respond to suggestions, and hypnotist-induced performance standards affected participants' responses to both hypnotic and nonhypnotic suggestions and their suggestion-related experiences. Suggestions were administered to 5 groups of participants using a test-retest design: (a) stringent performance standards; (b) lenient performance standards; (c) hypnosis test-retest; (d) no-hypnosis test-retest; and (e) no-hypnosis/hypnosis control. The authors found no support for the influence of a hypnotic induction or performance standards on responding to suggestions but found considerable support for the role of imaginative suggestibility and response expectancies in predicting responses to both hypnotic and nonhypnotic suggestions.

Clinical expectations: what facilitators expect from ESL students on clinical placement.

Science.gov (United States)

San Miguel, Caroline; Rogan, Fran

2012-03-01

Many nursing students for whom English is a second language (ESL) face challenges related to communication on clinical placement and although clinical facilitators are not usually trained language assessors, they are often in a position of needing to assess ESL students' clinical language performance. Little is known, however, about the particular areas of clinical performance facilitators focus on when they are assessing ESL students. This paper discusses the results of a study of facilitators' written assessment comments about the clinical performance of a small group of ESL nursing students over a two and a half year period. These comments were documented on students' clinical assessment forms at the end of each placement. The results provide a more detailed insight into facilitators' expectations of students' language performance and the particular challenges faced by ESL students and indicate that facilitators have clear expectations of ESL students regarding communication, learning styles and professional demeanour. These findings may help both ESL students and their facilitators better prepare for clinical placement. Copyright © 2011 Elsevier Ltd. All rights reserved.

To identify the expectations and perceptions of clients concerning the quality of hospital care provided to them and their respective companions at a private Brazilian hospital using SERVQUAL. The SERVQUAL questionnaire can provide information concerning expectations and perceptions of clients. In addition, it is able to identify the participation of frontline employees and how they contribute to the organization's end product (service delivery). In total, 172 inpatients for surgical reasons answered the SERVQUAL questionnaire. It consists of 23 pairs of statements, 22 of which are distributed into the dimensions of tangibles, reliability, responsiveness, assurance and empathy. Statement 23 refers to the overall quality of care. Exploratory analysis, internal consistency (Cronbach's alpha) and the kappa Coefficient were calculated using the Statistical Package for Social Sciences and SAS 9.2. Ethical approval was obtained from the Institutional Review Board at the Hospital das Clínicas at the University of São Paulo at Ribeirao Preto Medical School. Most participants had a bachelor's degree and were over than 60years old. Cronbach's alpha coefficients indicated good internal consistency (α=0.93) and high levels of agreement were observed (91.10%). The SERVQUAL questionnaire was sensitive to items in each dimension for which clients' perceptions surpassed their expectations. The continuous quality assessment of health services is mandatory for nursing leadership. The nursing leadership can further explore the SERVQUAL with a view to better attending to the clients' expectations. Copyright © 2017. Published by Elsevier Inc.

Expected performance of tracking and vertexing with the HL-LHC ATLAS detector

CERN Document Server

Calace, Noemi; The ATLAS collaboration

2018-01-01

The High Luminosity LHC (HL-LHC) aims to increase the LHC data-set by an order of magnitude in order to increase its potential for discoveries. Starting from the middle of 2026, the HL-LHC is expected to reach the peak instantaneous luminosity of $7.5 \\cdot 10^{34} cm^{-2}s^{-1}$ which corresponds to about 200 inelastic proton-proton collisions per beam crossing. To cope with the large radiation doses and high pileup, the current ATLAS Inner Detector will be replaced with a new all-silicon Inner Tracker. In this talk the expected performance of tracking and vertexing with the HL-LHC tracker is presented. Comparison is made to the performance with the Run2 detector. Ongoing developments of the track reconstruction for the HL-LHC are also discussed.

Olson, Corwin; Wright, Cinnamon; Long, Anne

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.

Schacht, Peter

2004-01-01

For the ATLAS detector at the LHC, the liquid argon technique is exploited for the electromagnetic calorimetry in the central part and for the electromagnetic and hadronic calorimetry in the forward and backward regions. The construction of the calorimeter is well advanced with full cold tests of the barrel calorimeter and first endcap calorimeter only months away. The status of the project is discussed as well as the related results from beam test studies of the various calorimeter subdetectors. The results show that the expected performance meets the ATLAS requirements as specified in the ATLAS Technical Design Report

The purpose of this study was to understand childbirth expectations and differences in childbirth expectations among expectant parents. For convenience sampling, 200 couples willing to participate in this study were chosen from two hospitals in central Taiwan. Inclusion criteria were at least 36 weeks of gestation, aged 18 and above, no prenatal complications, and willing to consent to participate in this study. Instruments used to collect data included basic demographic data and the Childbirth Expectations Questionnaire. Findings of the study revealed that (1) five factors were identified by expectant parents regarding childbirth expectations including the caregiving environment, expectation of labor pain, spousal support, control and participation, and medical and nursing support; (2) no general differences were identified in the childbirth expectations between expectant fathers and expectant mothers; and (3) expectant fathers with a higher socioeconomic status and who had received prenatal (childbirth) education had higher childbirth expectations, whereas mothers displayed no differences in demographic characteristics. The study results may help clinical healthcare providers better understand differences in expectations during labor and birth and childbirth expectations by expectant parents in order to improve the medical and nursing system and promote positive childbirth experiences and satisfaction for expectant parents.

Prosocial behavior refers to a broad category of actions that benefit other people or the society. Compared with other factors that affect prosocial performance, prosocial outcomes, consisting of prosocial gains and prosocial non-losses have received less attention up to now. In the current research, we explored the influences of different types of expected outcomes and regulatory focus on prosocial performance. Studies 1a and 1b examined the differences in prosocial performance elicited by prosocial gain (e.g., enhancing others’ access to clean water) and prosocial non-loss outcomes (e.g., protecting others from suffering dirty water). We found that the expected prosocial non-loss outcomes induced greater prosocial performance compared with the expected prosocial gain outcomes. Studies 2a and 2b examined the effects of dispositional and situational regulatory focus on prosocial loss aversion. We found that differences in prosocial performance between two expected prosocial outcomes were reduced when promotion focus was primed; whereas a primed prevention focus did not significantly increase this difference. Additionally, participants displayed a greater prosocial loss aversion in the prevention focus condition than in the promotion focus condition. The reason for the non-significant interaction between regulatory focus and expected prosocial outcome was discussed. PMID:27824909

Chamine, Irina; Oken, Barry S.

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

Prior expectations facilitate metacognition for perceptual decision.

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.

Expected commodity returns and pricing models

International Nuclear Information System (INIS)

Cortazar, Gonzalo; Kovacevic, Ivo; Schwartz, Eduardo S.

2015-01-01

Stochastic models of commodity prices have evolved considerably in terms of their structure and the number and interpretation of the state variables that model the underlying risk. Using multiple factors, different specifications and modern estimation techniques, these models have gained wide acceptance because of their success in accurately fitting the observed commodity futures' term structures and their dynamics. It is not well emphasized however that these models, in addition to providing the risk neutral distribution of future spot prices, also provide their true distribution. While the parameters of the risk neutral distribution are estimated more precisely and are usually statistically significant, some of the parameters of the true distribution are typically measured with large errors and are statistically insignificant. In this paper we argue that to increase the reliability of commodity pricing models, and therefore their use by practitioners, some of their parameters — in particular the risk premium parameters — should be obtained from other sources and we show that this can be done without losing any precision in the pricing of futures contracts. We show how the risk premium parameters can be obtained from estimations of expected futures returns and provide alternative procedures for estimating these expected futures returns. - Highlights: • Simple methodology to improve the performance of commodity pricing models • New information about commodity futures expected return is added to the estimation. • No significant effect in pricing futures contracts is observed. • More reliable commodity pricing model's expected returns are obtained. • Methodology is open to any expected futures return model preferred by practitioner

Green, Joseph P; Lynn, Steven Jay

2011-01-01

This study examines the effect of providing information linking participants' attitudes toward hypnosis with later hypnotic performance. Using total scale scores from McConkey's Opinions About Hypnosis scale, as well as subscale scores, the authors found a weak association between attitudes and performance among 460 student participants; however, the correlation was unaffected by prehypnotic information specifically connecting attitudes and performance. A brief, 3-item measure of hypnotic expectancies generated the strongest correlation with hypnotic responsiveness. The authors also found that the association between fantasy proneness and hypnotizability was unaffected by the order of scale administration. Finally, the study highlighted gender differences across measures of fantasy proneness, absorption, expectancy, and hypnotizability.

The influence of system quality characteristics on health care providers' performance: Empirical evidence from Malaysia.

Science.gov (United States)

Mohd Salleh, Mohd Idzwan; Zakaria, Nasriah; Abdullah, Rosni

The Ministry of Health Malaysia initiated the total hospital information system (THIS) as the first national electronic health record system for use in selected public hospitals across the country. Since its implementation 15 years ago, there has been the critical requirement for a systematic evaluation to assess its effectiveness in coping with the current system, task complexity, and rapid technological changes. The study aims to assess system quality factors to predict the performance of electronic health in a single public hospital in Malaysia. Non-probability sampling was employed for data collection among selected providers in a single hospital for two months. Data cleaning and bias checking were performed before final analysis in partial least squares-structural equation modeling. Convergent and discriminant validity assessments were satisfied the required criterions in the reflective measurement model. The structural model output revealed that the proposed adequate infrastructure, system interoperability, security control, and system compatibility were the significant predictors, where system compatibility became the most critical characteristic to influence an individual health care provider's performance. The previous DeLone and McLean information system success models should be extended to incorporate these technological factors in the medical system research domain to examine the effectiveness of modern electronic health record systems. In this study, care providers' performance was expected when the system usage fits with patients' needs that eventually increased their productivity.

Haas, Mitchell; Aickin, Mikel; Vavrek, Darcy

2010-01-01

The purpose of this article was to present a preliminary model to identify the effects of expectancy of treatment success and the patient-provider encounter (PPE) on outcomes in an open-label randomized trial. Eighty participants with chronic cervicogenic headache (CGH) were randomized to 4 groups: 2 levels of treatment dose (8 or 16) and 2 levels of therapy from a chiropractor (spinal manipulation or light massage). Providers were instructed to have equal enthusiasm for all care. Structural equation modeling with standardized path coefficients (beta) was used in a path analysis to identify the effects of patient expectancy and the PPE on CGH pain. The model included monthly pain from baseline to 12 weeks. Expectancy and PPE were evaluated on Likert scales. The patient-provider encounter was measured as patient perception of chiropractor enthusiasm, confidence, and comfort with care. Baseline patient expectancy was balanced across groups. The PPE measures were balanced across groups and consistent over the 8-week treatment period. Treatment and baseline pain had the strongest effects on pain outcomes (|beta| = .46-.59). Expectations had little effect on pain (abs value(beta) value(beta)= .03-.27) and on subsequent confidence in treatment success (abs value(beta)= .09 and .12). Encouraging equipoise in the PPE and balancing expectancy across treatment groups may protect against some confounding related to the absence of blinding in a randomized controlled trial of pain. In this trial, their effects were found to be small relative to the effects of treatment and baseline values. Copyright 2010 National University of Health Sciences. Published by Mosby, Inc.

Stickney, Carolyn A; Ziniel, Sonja I; Brett, Molly S; Truog, Robert D

2014-12-01

To compare perceptions, goals, and expectations of health care providers and parents regarding parental participation in morning rounds and target specific areas of opportunity for educational interventions. Semistructured interviews of parents and focus groups of health care providers to learn about their experiences in, goals for, and perceived barriers to successful parental participation in morning rounds. Qualitative methods were used to analyze interview and focus group transcripts. Parents (n = 21) and health care providers (n = 24) participated in interviews and focus groups, respectively. Analyses revealed key areas of agreement between providers and parents regarding goals for rounds when parents are present, including helping parents achieve an understanding of the child's current status and plan of care. Providers and parents disagreed, however, about the nature of opportunities to ask questions. Parents additionally reported a strong desire to provide expert advice about their children and expected transparency from their care team, while providers stated that parental presence sometimes hindered frank discussions and education. Some agreement in goals for parent participation in morning rounds exists, although there are opportunities to calibrate expectations for both parents and health care providers. Solutions may involve a protocol for orienting parents to morning rounds, focusing on improving communication with parents outside of morning rounds, and the preservation of a forum for providers to have private discussions as a team.

2017-10-01

In a recent study by Chauvel, Wulf, and Maquestiaux (2015), golf putting performance was found to be affected by the Ebbinghaus illusion. Specifically, adult participants demonstrated more effective learning when they practiced with a hole that was surrounded by small circles, making it look larger, than when the hole was surrounded by large circles, making it look smaller. The present study examined whether this learning advantage would generalize to children who are assumed to be less sensitive to the visual illusion. Two groups of 10-year olds practiced putting golf balls from a distance of 2m, with perceived larger or smaller holes resulting from the visual illusion. Self-efficacy was increased in the group with the perceived larger hole. The latter group also demonstrated more accurate putting performance during practice. Importantly, learning (i.e., delayed retention performance without the illusion) was enhanced in the group that practiced with the perceived larger hole. The findings replicate previous results with adult learners and are in line with the notion that enhanced performance expectancies are key to optimal motor learning (Wulf & Lewthwaite, 2016).

What's that, you say? Employee expectations of privacy when using employer-provided technology--and how employers can defeat them.

Science.gov (United States)

Herrin, Barry S

2012-01-01

Two 2010 court cases that determined the effectiveness of policies governing employees' use of employer-provided communication devices can be used to guide employers when constructing their own technology policies. In light of a policy that stated that "users should have no expectation of privacy or confidentiality," one case established that the employer was in the right. However, a separate case favored the employee due, in part, to an "unclear and ambiguous" policy. Ultimately, employers can restrict the use of employer-furnished technology by employees by: 1) clearly outlining that employees do not have a reasonable expectation of privacy in their use of company devices; 2) stating that any use of personal e-mail accounts using employer-provided technology will be subject to the policy; 3) detailing all technology used to monitor employees; 4) identifying company devices covered; 5) not exposing the content of employee communications; and 6) having employees sign and acknowledge the policy.

OSIRIS-REx is the third spacecraft in the NASA New Frontiers Program and is planned for launch in 2016. OSIRIS-REx will orbit the near-Earth asteroid (101955) Bennu, characterize it, and return a sample of the asteroid's regolith back to Earth. The Regolith X-ray Imaging Spectrometer (REXIS) is an instrument on OSIRIS-REx designed and built by students at MIT and Harvard. The purpose of REXIS is to collect and image sun-induced fluorescent X-rays emitted by Bennu, thereby providing spectroscopic information related to the elemental makeup of the asteroid regolith and the distribution of features over its surface. Telescopic reflectance spectra suggest a CI or CM chondrite analog meteorite class for Bennu, where this primitive nature strongly motivates its study. A number of factors, however, will influence the generation, measurement, and interpretation of the X-ray spectra measured by REXIS. These include: the compositional nature and heterogeneity of Bennu, the time-variable solar state, X-ray detector characteristics, and geometric parameters for the observations. In this paper, we will explore how these variables influence the precision to which REXIS can measure Bennu's surface composition. By modeling the aforementioned factors, we place bounds on the expected performance of REXIS and its ability to ultimately place Bennu in an analog meteorite class.

Performance monitoring in the anterior cingulate is not all error related: expectancy deviation and the representation of action-outcome associations.

Science.gov (United States)

Oliveira, Flavio T P; McDonald, John J; Goodman, David

2007-12-01

Several converging lines of evidence suggest that the anterior cingulate cortex (ACC) is selectively involved in error detection or evaluation of poor performance. Here we challenge this notion by presenting event-related potential (ERP) evidence that the feedback-elicited error-related negativity, an ERP component attributed to the ACC, can be elicited by positive feedback when a person is expecting negative feedback and vice versa. These results suggest that performance monitoring in the ACC is not limited to error processing. We propose that the ACC acts as part of a more general performance-monitoring system that is activated by violations in expectancy. Further, we propose that the common observation of increased ACC activity elicited by negative events could be explained by an overoptimistic bias in generating expectations of performance. These results could shed light into neurobehavioral disorders, such as depression and mania, associated with alterations in performance monitoring and also in judgments of self-related events.

Expectations are thought to affect how citizens form their attitudes and behavior toward public services. Such attitudes may include citizen satisfaction, where expectations play a fundamental role, and relevant behaviors include choice of services and the decision to voice opinions about them....... However, there are few investigations into what drives citizen expectations and even fewer that consider these relationships across time. This article tests whether prior expectations, perceived performance, and citizen satisfaction influence future expectations, using a unique dataset that follows...... individual citizens across two subsequent school satisfaction surveys from 2011 and 2013. The results show that prior expectations have a large and consistent influence on future expectations, as predicted by the literature, whereas the influence from prior perceived performance seems less consistent. Prior...

The present studies examined whether colorblind diversity messages, relative to multicultural diversity messages, serve as an identity threat that undermines performance-related outcomes for individuals at the intersections of race and gender. We exposed racial/ethnic majority and minority women and men to either a colorblind or multicultural diversity statement and then measured their expectations about overall diversity, anticipated bias, and group task performance (Study 1, N = 211), as well as their expectations about distinct race and gender diversity and their actual performance on a math test (Study 2, N = 328). Participants expected more bias (Study 1) and less race and gender diversity (Study 2) after exposure to a colorblind versus a multicultural message. However, the colorblind message was particularly damaging for women of color, prompting them to expect the least diversity overall and to perform worse (Study 1), as well as to actually perform worse on a math test (Study 2) than the multicultural message. White women demonstrated the opposite pattern, performing better on the math test in the colorblind versus the multicultural condition, whereas racial minority and majority men's performances were not affected by different messages about diversity. We discuss the importance of examining psychological processes that underscore performance-related outcomes at the junction of race and gender. (c) 2015 APA, all rights reserved).

The experimenter expectancy effect confound remains largely unexplored in neuropsychological research and has never been investigated among cannabis users. This study investigated whether examiner expectancies of cannabis user status affected examinees' neuropsychological performance. Participants included 41 cannabis users and 20 non-users. Before testing, examiners who were blind to participant user status privately rated whether they believed the examinee was a cannabis user or non-user. Examiners then administered a battery of neuropsychological and performance validity measures. Multiple regression analyses compared performance between examinees judged as cannabis users (n = 37) and those judged as non-users (n = 24). Examiners' judgments of cannabis users were 75% accurate; judgments of non-users were at chance. After controlling for age, gender, and actual user status, examiner judgments of cannabis user status predicted performance on two measures (California Verbal Learning Test-II, and Trail Making Test B; p users obtained lower scores than those judged as non-users. Examiners' judgments of cannabis user status predicted performance even after controlling for actual user status, indicating vulnerability to examiner expectancy effects. These findings have important implications for both research and clinical settings, as scores may partially reflect examiners' expectations regarding cannabis effects rather than participants' cognitive abilities. These results demonstrate the need for expectancy effect research in the neuropsychological assessment of all populations, not just cannabis users. © The Author(s) 2018.

LHCb : Performance, radiation resistance, and expectations of the Outer Tracker straw

CERN Multimedia

Tuning, Niels

2015-01-01

The LHCb experiment is a single arm spectrometer, designed to study CP violation in B-decays at the LHC. It is crucial to accurately and efficiently detect the charged decay particles, in the high-density particle environment of the LHC. For this, the Outer Tracker (OT) was constructed, consisting of 54,000 straw tubes, covering in total an area of 360 m2 of double layers. The detector operated in 2011/2012 under large particle rates, up to 100 kHz/cm per straw in the region closest to the beam. The performance of the OT detector during Run-I of the LHC has been studied in detail, in terms of efficiency, resolution and noise rate. Particular attention is devoted to the radiation hardness of this sensitive gaseous detector, that has shown to suffer from gain loss after mild irradiation in laboratory conditions. During the shutdown period of the LHC, extensive studies have been performed on subtle spatial alignment effects, and real-time calibration procedures have been prepared for run-II. In addition, expect...

Full Text Available Introduction: Outcome expectation is considered as a basic and significant variable in education. It is a cognitive-motivational component that takes the individual into account as an active and sensible decision-maker. The present study was conducted to investigate the correlation of outcome expectations with academic performance of students of nursing and midwifery in Kermanshah University of Medical Sciences. Methods: In this descriptive cross-sectional study, the sample size included 218 nursing and midwifery students selected through convenient random sampling method. The instrument for data collection was the questionnaire of “outcome expectations of career decision-making and discovery targets”, which comprised of 13 questions in three domains of future orientation, job satisfaction and personal expectations. The questionnaires were coded after being completed and the obtained data were fed into SPSS-16 software and analyzed by descriptive statistics, t-test, Kolmogrov-Smirnov, ANOVA and Mann-Whitney tests. Results: The findings indicated no statistically significant difference between place of living (dormitory or home and outcome expectations along with its domains (39.4% and 60-6%. However, a significant correlation was reported between discipline, gender, admittance year and academic performance of the students (p0.05. Conclusion: The findings of this study indicated a positively positive significant relationship between students’ academic performance and outcome expectations along with its domains.

The Effect of Incorrect Reliability Information on Expectations, Perceptions, and Use of Automation.

Barg-Walkow, Laura H; Rogers, Wendy A

2016-03-01

We examined how providing artificially high or low statements about automation reliability affected expectations, perceptions, and use of automation over time. One common method of introducing automation is providing explicit statements about the automation's capabilities. Research is needed to understand how expectations from such introductions affect perceptions and use of automation. Explicit-statement introductions were manipulated to set higher-than (90%), same-as (75%), or lower-than (60%) levels of expectations in a dual-task scenario with 75% reliable automation. Two experiments were conducted to assess expectations, perceptions, compliance, reliance, and task performance over (a) 2 days and (b) 4 days. The baseline assessments showed initial expectations of automation reliability matched introduced levels of expectation. For the duration of each experiment, the lower-than groups' perceptions were lower than the actual automation reliability. However, the higher-than groups' perceptions were no different from actual automation reliability after Day 1 in either study. There were few differences between groups for automation use, which generally stayed the same or increased with experience using the system. Introductory statements describing artificially low automation reliability have a long-lasting impact on perceptions about automation performance. Statements including incorrect automation reliability do not appear to affect use of automation. Introductions should be designed according to desired outcomes for expectations, perceptions, and use of the automation. Low expectations have long-lasting effects. © 2015, Human Factors and Ergonomics Society.

Although boys outshine girls in a range of motor skills, there are no reported gender differences in motor performance during infancy. This study examined gender bias in mothers' expectations about their infants' motor development. Mothers of 11-month-old infants estimated their babies' crawling ability, crawling attempts, and motor decisions in a novel locomotor task-crawling down steep and shallow slopes. Mothers of girls underestimated their performance and mothers of boys overestimated their performance. Mothers' gender bias had no basis in fact. When we tested the infants in the same slope task moments after mothers' provided their ratings, girls and boys showed identical levels of motor performance. Copyright 2000 Academic Press.

Changing mortality and average cohort life expectancy

Directory of Open Access Journals (Sweden)

Robert Schoen

2005-10-01

Full Text Available Period life expectancy varies with changes in mortality, and should not be confused with the life expectancy of those alive during that period. Given past and likely future mortality changes, a recent debate has arisen on the usefulness of the period life expectancy as the leading measure of survivorship. An alternative aggregate measure of period mortality which has been seen as less sensitive to period changes, the cross-sectional average length of life (CAL has been proposed as an alternative, but has received only limited empirical or analytical examination. Here, we introduce a new measure, the average cohort life expectancy (ACLE, to provide a precise measure of the average length of life of cohorts alive at a given time. To compare the performance of ACLE with CAL and with period and cohort life expectancy, we first use population models with changing mortality. Then the four aggregate measures of mortality are calculated for England and Wales, Norway, and Switzerland for the years 1880 to 2000. CAL is found to be sensitive to past and present changes in death rates. ACLE requires the most data, but gives the best representation of the survivorship of cohorts present at a given time.

Incentive payments are not related to expected health gain in the pay for performance scheme for UK primary care: cross-sectional analysis

2012-04-01

Full Text Available Abstract Background The General Medical Services primary care contract for the United Kingdom financially rewards performance in 19 clinical areas, through the Quality and Outcomes Framework. Little is known about how best to determine the size of financial incentives in pay for performance schemes. Our aim was to test the hypothesis that performance indicators with larger population health benefits receive larger financial incentives. Methods We performed cross sectional analyses to quantify associations between the size of financial incentives and expected health gain in the 2004 and 2006 versions of the Quality and Outcomes Framework. We used non-parametric two-sided Spearman rank correlation tests. Health gain was measured in expected lives saved in one year and in quality adjusted life years. For each quality indicator in an average sized general practice we tested for associations first, between the marginal increase in payment and the health gain resulting from a one percent point improvement in performance and second, between total payment and the health gain at the performance threshold for maximum payment. Results Evidence for lives saved or quality adjusted life years gained was found for 28 indicators accounting for 41% of the total incentive payments. No statistically significant associations were found between the expected health gain and incentive gained from a marginal 1% increase in performance in either the 2004 or 2006 version of the Quality and Outcomes Framework. In addition no associations were found between the size of financial payment for achievement of an indicator and the expected health gain at the performance threshold for maximum payment measured in lives saved or quality adjusted life years. Conclusions In this subgroup of indicators the financial incentives were not aligned to maximise health gain. This disconnection between incentive and expected health gain risks supporting clinical activities that are only

Support and education for parents faced with managing a child with atopic dermatitis is crucial to the success of current treatments. Interventions aiming to improve parent management of this condition are promising. Unfortunately, evaluation is hampered by lack of precise research tools to measure change. To develop a suite of valid and reliable research instruments to appraise parents' self-efficacy for performing atopic dermatitis management tasks; outcome expectations of performing management tasks; and self-reported task performance in a community sample of parents of children with atopic dermatitis. The Parents' Eczema Management Scale (PEMS) and the Parents' Outcome Expectations of Eczema Management Scale (POEEMS) were developed from an existing self-efficacy scale, the Parental Self-Efficacy with Eczema Care Index (PASECI). Each scale was presented in a single self-administered questionnaire, to measure self-efficacy, outcome expectations, and self-reported task performance related to managing child atopic dermatitis. Each was tested with a community sample of parents of children with atopic dermatitis, and psychometric evaluation of the scales' reliability and validity was conducted. A community-based convenience sample of 120 parents of children with atopic dermatitis completed the self-administered questionnaire. Participants were recruited through schools across Australia. Satisfactory internal consistency and test-retest reliability was demonstrated for all three scales. Construct validity was satisfactory, with positive relationships between self-efficacy for managing atopic dermatitis and general perceived self-efficacy; self-efficacy for managing atopic dermatitis and self-reported task performance; and self-efficacy for managing atopic dermatitis and outcome expectations. Factor analyses revealed two-factor structures for PEMS and PASECI alike, with both scales containing factors related to performing routine management tasks, and managing the

The Linkage Between Work Unit Performance Perceptions of U.S. Federal Employees and Their Job Satisfaction: An Expectancy Theory

Directory of Open Access Journals (Sweden)

Soyoung PARK

2018-02-01

Full Text Available Public organizations are interested in how to improve their performance. Performance in a work unit can also influence employee job satisfaction due to positive expectations based on higher performance. Thus, our study attempts to investigate if organizational performance has an impact on employee motivation under the premise that employees who perform better in a work unit expect greater professional recognition and rewards. By using data from the 2013 Federal Employee Viewpoint Survey (FEVS, we find that employees who perceive higher levels of performance in a work unit have a higher level of job satisfaction. This paper further shows that performance perception based on rewards is also positively related to job satisfaction.However, underrepresented groups (female and non-white, older employees and mid-level (work experience from 6 to 14 years employees are less satisfied with higher work unit performance. Finally, employees in the distributive agency category are more satisfied with work unit performance while those in the regulatory agency category are less satisfied with work unit performance. In conclusion, organizations should recognize particular characteristics of employees to develop the policies related to performance management, and effectively utilize these policies in order to attract and retain proficient workers.

Beyond satisfaction, what service users expect of inpatient mental health care: a literature review.

Science.gov (United States)

Hopkins, J E; Loeb, S J; Fick, D M

2009-12-01

To provide efficient and effective inpatient mental health services, it is imperative to not only ascertain if service users are satisfied with the care received from nurses, but also the degree to which initial expectations are being met. Ten reports of primary research on service users' experiences, perceptions and expectations of inpatient mental health care were examined to understand what service users' expect of inpatient mental health care and the implications for nursing practice. The World Health Organization's description of responsiveness to service users' non-medical expectations of care was used as a framework for retrieving literature and organizing the research outcomes. Responsiveness includes seven categories of healthcare performance ranging from respect for the dignity of the person, to adequacy of amenities, and choice of provider. Service users expect to form interpersonal relationships with nurses; however, non-clinical responsibilities serve as barriers which consume considerable available nursing time that otherwise could be spent developing therapeutic relationships. In addition, inpatient programming ideas are identified for the provision of better services. Hospitals' expectations of mental health nurses will need to be reconsidered if these nurses are to provide the time and resources necessary to meet current service users' expectations.

Gender differences and the definition of success: male and female veterinary students' career and work performance expectations.

Science.gov (United States)

Kogan, Lori R; McConnell, Sherry L; Schoenfeld-Tacher, Regina

2004-01-01

This article addresses the challenges that gender performance expectations create within the veterinary profession. An investigation of veterinary students' perceptions of the essential characteristics that define successful veterinarians and veterinary students, and the gender differences within these definitions, is described. Because previous research supports the premise that the standards required for success differ for males and females, it is likely that male and female veterinary students possess different career expectations and definitions of career success. The ramifications of these differences are explored, and proposed strategies to address this issue, in the form of student support services, are discussed.

A review of expectancy theory and alcohol consumption.

Science.gov (United States)

Jones, B T; Corbin, W; Fromme, K

2001-01-01

Research is reviewed on the association between alcohol outcome expectancies and consumption which has led many to argue that manipulating expectancies might be a route to manipulating consumption for problem prevention and treatment. Studies indirectly and directly evaluating this latter position are reviewed. Expectancies predicting treatment outcome: two studies have shown that the more positive expectancies held at treatment, the poorer is treatment outcome, but five other studies have failed to find this. Three related studies have shown that the more negative expectancies held at treatment, the better the treatment outcome. This evaluation provides evidence inconsistent with the main position for positive expectancy and limited support for negative. Expectancy manipulations and ad libitum consumption: three studies in the laboratory have shown that increasing positive expectancies through word priming increases subsequent consumption and two studies have shown that increasing negative expectancies decreases it. A single study in the field showed a similar relationship. This evaluation provides evidence consistent with the main position but is limited by measuring consumption changes over only 1-2 hours. Prevention programmes with expectancy components: seven projects are reviewed in which positive expectancies were targeted, but only two report an expectancy change analysis and in both cases the expectancy change did not relate to subsequent consumption. This evaluation provides evidence inconsistent with the main position. Expectancy challenge: two related studies are reviewed in which positive expectancy challenges reduce subsequent consumption but changes in expectancy were not evaluated as predictors of consumption change. Two studies are reviewed which found a reduction in positive expectancy following expectancy challenge but no reduction in consumption. One study is reviewed in which when negative expectancy was increased in treatment there was a

Numerous guidelines for students and medical professionals provide the instructions of proper behavior during encounters with patients in a doctor's office. However, they quite often do not consider cultural differences that may affect the doctor-patient relationship. In our study we analyzed Polish patients' expectations (N = 976) for their physicians' actual behavior. We compared our results with analogue studies performed in the United States. We determined that patient expectations concerning a desirable form of verbal and nonverbal communication with a physician vary to a considerable degree. Relatively universal, however, is the wish that the doctors introduce themselves and apply personalized forms of contact.

The role of multisensory interplay in enabling temporal expectations.

Ball, Felix; Michels, Lara E; Thiele, Carsten; Noesselt, Toemme

2018-01-01

Temporal regularities can guide our attention to focus on a particular moment in time and to be especially vigilant just then. Previous research provided evidence for the influence of temporal expectation on perceptual processing in unisensory auditory, visual, and tactile contexts. However, in real life we are often exposed to a complex and continuous stream of multisensory events. Here we tested - in a series of experiments - whether temporal expectations can enhance perception in multisensory contexts and whether this enhancement differs from enhancements in unisensory contexts. Our discrimination paradigm contained near-threshold targets (subject-specific 75% discrimination accuracy) embedded in a sequence of distractors. The likelihood of target occurrence (early or late) was manipulated block-wise. Furthermore, we tested whether spatial and modality-specific target uncertainty (i.e. predictable vs. unpredictable target position or modality) would affect temporal expectation (TE) measured with perceptual sensitivity (d ' ) and response times (RT). In all our experiments, hidden temporal regularities improved performance for expected multisensory targets. Moreover, multisensory performance was unaffected by spatial and modality-specific uncertainty, whereas unisensory TE effects on d ' but not RT were modulated by spatial and modality-specific uncertainty. Additionally, the size of the temporal expectation effect, i.e. the increase in perceptual sensitivity and decrease of RT, scaled linearly with the likelihood of expected targets. Finally, temporal expectation effects were unaffected by varying target position within the stream. Together, our results strongly suggest that participants quickly adapt to novel temporal contexts, that they benefit from multisensory (relative to unisensory) stimulation and that multisensory benefits are maximal if the stimulus-driven uncertainty is highest. We propose that enhanced informational content (i.e. multisensory

Novel methods and expected run II performance of ATLAS track reconstruction in dense environments

CERN Document Server

Jansky, Roland Wolfgang; The ATLAS collaboration

2015-01-01

Detailed understanding and optimal track reconstruction performance of ATLAS in the core of high pT objects is paramount for a number of techniques such as jet energy and mass calibration, jet flavour tagging, and hadronic tau identification as well as measurements of physics quantities like jet fragmentation functions. These dense environments are characterized by charged particle separations on the order of the granularity of ATLAS’s inner detector. With the insertion of a new innermost layer in this tracking detector, which allows measurements closer to the interaction point, and an increase in the centre of mass energy, these difficult environments will become even more relevant in Run II, such as in searches for heavy resonances. Novel algorithmic developments to the ATLAS track reconstruction software targeting these topologies as well as the expected improved performance will be presented.

Use of Groundwater Lifetime Expectancy for the Performance Assessment of Deep Geologic Radioactive Waste Repositories.

Science.gov (United States)

Cornaton, F.; Park, Y.; Normani, S.; Sudicky, E.; Sykes, J.

2005-12-01

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, the safety of the host repository depends on two main barriers: the engineered barrier and the natural geological barrier. 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 the 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 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 equation subject to a properly posed set of boundary conditions. It can then be used to define optimal repository locations. In a second step, the risk associated with selected sites can be evaluated by simulating an appropriate contaminant release history. The proposed methodology is applied in the context of a typical Canadian Shield environment. Based on a statistically-generated three-dimension network of fracture zones embedded in the granitic host rock, the sensitivity and the uncertainty of lifetime expectancy to the hydraulic and dispersive properties of the fracture network, including the impact of conditioning via their surface expressions, is computed in order to demonstrate the utility of the methodology.

Composite Measures of Health Care Provider Performance: A Description of Approaches

Science.gov (United States)

Shwartz, Michael; Restuccia, Joseph D; Rosen, Amy K

2015-01-01

Context Since the Institute of Medicine’s 2001 report Crossing the Quality Chasm, there has been a rapid proliferation of quality measures used in quality-monitoring, provider-profiling, and pay-for-performance (P4P) programs. Although individual performance measures are useful for identifying specific processes and outcomes for improvement and tracking progress, they do not easily provide an accessible overview of performance. Composite measures aggregate individual performance measures into a summary score. By reducing the amount of data that must be processed, they facilitate (1) benchmarking of an organization’s performance, encouraging quality improvement initiatives to match performance against high-performing organizations, and (2) profiling and P4P programs based on an organization’s overall performance. Methods We describe different approaches to creating composite measures, discuss their advantages and disadvantages, and provide examples of their use. Findings The major issues in creating composite measures are (1) whether to aggregate measures at the patient level through all-or-none approaches or the facility level, using one of the several possible weighting schemes; (2) when combining measures on different scales, how to rescale measures (using z scores, range percentages, ranks, or 5-star categorizations); and (3) whether to use shrinkage estimators, which increase precision by smoothing rates from smaller facilities but also decrease transparency. Conclusions Because provider rankings and rewards under P4P programs may be sensitive to both context and the data, careful analysis is warranted before deciding to implement a particular method. A better understanding of both when and where to use composite measures and the incentives created by composite measures are likely to be important areas of research as the use of composite measures grows.

The issue of the expectations of elite athletes, their coaches and non-medically qualified athlete support staff of consultations with sports physicians has not been previously dealt with in the sports medicine literature. As fulfillment of expectations of the content of a consultation may influence patient's satisfaction and clinical outcome, it is important to assess the expectations of athletes and, most importantly, coaches. To assess the expectations and beliefs about fatigue, particularly in relation to blood tests, of athletes, their coaches and support staff in the specific context of tiredness of sports science or non-medically qualified sports medicine staff, 22 elite coaches and 62 elite athletes from the Australian Institute of Sport were included in this study. A single questionnaire. The expectation for a blood test at the initial consultation for short-term fatigue was particularly high among athletes (81%) and coaches (91%). This expectation increased in athletes if their performance was worsening. All groups unanimously suggested that a blood test be performed in cases of more prolonged fatigue. Increase in total training load was perceived to be the most important cause of fatigue, but issues relating to sleep were also thought to be highly relevant. All groups suggested that blood tests provide some degree of reassurance, and all groups suggested that the most important blood tests that might be performed related to exclusion of iron deficiency, anaemia and infection. Athletes and their coaches generally expect that blood tests will be performed even when fatigue has been present for performed.

Background: "Adolescent pregnancy is one of the most pressing, persistent, and poignant problems facing society" (Yoos, 1987, p. 247). Manitoba's teen pregnancy rates are among the highest in Canada. Yet, little is known about adolescent fathers and their parenting involvement. The purpose of this descriptive correlational study was to explore variables which may influence teen fathers' participation in parenting.Methods: A convenience sample of 30 adolescent fathers, whose partners were attending an Adolescent Prenatal Clinic, completed two questionnaires: Offer Self-Image-Revised, and Perceived Parenting Role Performance. Guided by family role theory, four hypotheses were examined utilizing a quantitative research method.Results: Data analysis revealed that 30% of these respondents had a low to very low self-image. Pearson's correlation coefficient, which facilitated hypotheses testing, failed to validate a relationship between teen fathers' perceived role performance and self-image, and perceived parenting role expectations. Nevertheless, a moderate negative correlation was noted between teen fathers' self-image and their perceived parenting role expectations (r = -.35, p adolescence with the responsibilities of fatherhood increase their vulnerability to parenting failure.

Investigating the expected long-term production performance of shale reservoirs

Although there is global interest in developing shale plays, the traditional volumetric and material balance approaches that are used for petroleum asset evaluation do not address the special attributes of such formations. The performance of a particular deposit is currently determined by analyzing historical records statistically in developed areas and applying the derived type curves in new areas by assuming performance similarity. The assumption of similarity is challenged by the wealth of parameters influencing performance, which tend to differ, introducing considerable uncertainties into predictions. Historical records support only the early production history, while late performance is extrapolated without many reference points to match. This paper presented an investigation of the applicability of traditional and non-traditional empirical, analytical and numerical methods that are used to predict shale well performance. The purpose of the study was to rationalize the link between natural/stimulated rock description with oil and gas recovery mechanisms in a manner that is practical at different scales of resolution and covers early and late times. The paper discussed the use of special features such as flow through fracture networks, gas desorption and geomechanical effects that are incorporated in numerical simulation in a way that relates to the measurable petrophysical and geophysical input. The paper described the shale engineering concept and provided a description of the model. The Eagle Ford shale was presented as a case study. It was concluded that a reservoir simulation model with pseudo-lateral connections could describe the flow behaviour of a typical shale well, and could match shale gas well performance even if limited information was available. 20 refs., 9 figs.

Making gender matter: the role of gender-based expectancies and gender identification on women's and men's math performance in Sweden.

It is well established that an emphasis on gender differences may have a negative effect on women's math performance in USA, Germany and the Netherlands. It has further been found that an individual's identification with the stereotyped group may moderate effects of negative stereotypes. The present study investigated how gender-based expectancies affected the math performance of women and men in Sweden, a nation with a smaller gender gap than in other countries, and a strong cultural emphasis on gender equality. Participants, 112 female and 74 male undergraduate math students from Swedish universities, completed a difficult math test in which their gender was either linked to their test performance or not. Men performed better than women when gender was made relevant among participants who did not see their gender as an important aspect of their identity, while participants high in gender identification were unaffected by gender identity relevance. Moreover, the gender relevance manipulation affected men's performance more than women's. The results deviate from findings on US samples, indicating that the role of group identification as a moderator of stereotype-based expectancy effects is complex, and that factors in the cultural context may interact with individual differences in identification to determine the impact of negative stereotypes.

Full Text Available Introduction: Quality of research in PhD programs increases if supervisors become aware of students' expectations from them. This qualitative study aimed to explore expectations of PhD students from their supervisors was done.   Methods: This qualitative content analysis study was conducted on 22 graduated PhD students of Iran University of Medical Sciences, in 2014. The samples were purposefully selected and interviewed. All interviews were recorded and transcribed verbatim.   Results: After analyzing and coding data, it was found that PhD students have four main expectations from their supervisors. These expectations consist of scientific support including help with selection of subject, preparation and registration of proposal, data collection and support for writing and examination of the thesis. Developing scientific skills and help with preparing manuscripts were other expectations. Emotional-social support with five categories including relationship between supervisor-student, general expectations of supervisor, supervisor personality characteristics, needed emotional skills and social activities related to thesis and finally providing adequate resources including financial support and access to facilities inside and outside the university were among the other expectations.   Conclusion: PhD students need to scientific, emotional, social and material supports from their supervisors in the process of performing thesis. These expectations should be told to supervisors.

Competing expectations. The case of the hydrogen car

Energy Technology Data Exchange (ETDEWEB)

Bakker, S.

2011-04-15

Firms and governments can support only a limited number of emerging technologies. Some emerging technologies receive support for further development while others are discarded. But how do decision makers in firms and governments assess which of the options earns their support? Straightforward assessments of prices and performance levels can not be sufficient as emerging technologies are, by definition, in an early stage of development and have not reached their maximum levels of performance yet. It is therefore not so much of interest which of the options performs best at any point in time, but rather which of the options will eventually perform best in the future. As a consequence, this competition is based on expectations about future price and performance levels. It is studied how both the relevant decision makers and the technology developers deal with these expectations about the different options. The development of the hydrogen car takes up a central position in this thesis. The hydrogen car is one of the contenders in the race towards 'the car of the future'. While the hydrogen car is indeed in competition with the other contenders there is also competition between different configurations of the hydrogen car. Expectations with regard to the different options are measured through patents, prototype cars, and statements from scientists and car manufacturers. From the research it shows that technology developers, the enactors, do not only try to shape positive expectations about their own option, but also negative expectations about their competitors. Technology selectors assess the credibility of the diverse expectations mainly on the basis of past progress and the possible paths forward towards higher levels of performance and lower prices. The roles of enactor and selector are interrelated and so is the process of enaction and selection. A main conclusion to this thesis is that selectors tend to narrow their portfolios in times of low general

Full Text Available Abstract Background Estimates of life expectancy assist physicians and patients in medical decision-making. The time-delayed benefits for many medical treatments make an older adult's life expectancy estimate particularly important for physicians. The purpose of this study is to assess older adults' beliefs about physician-estimated life expectancy. Methods We performed a mixed qualitative-quantitative cross-sectional study in which 116 healthy adults aged 70+ were recruited from two local retirement communities. We interviewed them regarding their beliefs about physician-estimated life expectancy in the context of a larger study on cancer screening beliefs. Semi-structured interviews of 80 minutes average duration were performed in private locations convenient to participants. Demographic characteristics as well as cancer screening beliefs and beliefs about life expectancy were measured. Two independent researchers reviewed the open-ended responses and recorded the most common themes. The research team resolved disagreements by consensus. Results This article reports the life-expectancy results portion of the larger study. The study group (n = 116 was comprised of healthy, well-educated older adults, with almost a third over 85 years old, and none meeting criteria for dementia. Sixty-four percent (n = 73 felt that their physicians could not correctly estimate their life expectancy. Sixty-six percent (n = 75 wanted their physicians to talk with them about their life expectancy. The themes that emerged from our study indicate that discussions of life expectancy could help older adults plan for the future, maintain open communication with their physicians, and provide them knowledge about their medical conditions. Conclusion The majority of the healthy older adults in this study were open to discussions about life expectancy in the context of discussing cancer screening tests, despite awareness that their physicians' estimates could be inaccurate

Towards a Characterization of Rational Expectations

OpenAIRE

Itai Arieli

2008-01-01

R. J. Aumann and J. H. Drèze (2008) define a rational expectation of a player i in a game G as the expected payo of some type of i in some belief system for G in which common knowledge of rationality and common priors obtain. Our goal is to characterize the set of rational expectations in terms of the game's payoff matrix. We provide such a characterization for a specific class of strategic games, called semi-elementary, which includes Myerson's "elementary" games.

[Expectations and patient satisfaction in hospitals: construction and application of an expectation-based experience typology and its use in the management of quality and expectations].

Gehrlach, Christoph; Güntert, Bernhard

2015-01-01

Patient satisfaction (PS) surveys are frequently used evaluation methods to show performance from the customer's view. This approach has some fundamental deficits, especially with respect to theory, methodology and usage. Because of the significant theoretical value of the expectation confirmation/disconfirmation concept in the development of PS, an expectation-based experience typology has been developed and tested to check whether this approach could be a theoretical and practical alternative to the survey of PS. Due to the mainly cognitive-rational process of comparison between expectations and expectation fulfilment, it is easier to make changes in this stage of the process than in the subsequent stage of the development of PS that is mainly based on emotional-affective processes. The paper contains a literature review of the common concept of PS and its causal and influencing factors. Based on the theoretical part of this study, an expectation-based experience typology was developed. In the next step, the typology was subjected to exploratory testing, based on two patient surveys. In some parts of the tested typology explorative differences could be found between hospitals. Despite this rather more complex and unusual approach to expectation-based experience typology, this concept offers the chance to change conditions not only retrospectively (based on data), but also in a prospective way in terms of a "management of expectations".

The dual purpose of this project was to contribute to basic knowledge about the interaction between regulation and innovation and to inform the cost and benefit expectations related to technical change which are embedded in the rulemaking process of an important area of national regulation. The area of regulation focused on here is minimum efficiency performance standards (MEPS) for appliances and other energy-using products. Relevant both to U.S. climate policy and energy policy for buildings, MEPS remove certain product models from the market that do not meet specified efficiency thresholds.

This study examines the effectiveness of a communication skill training based on a coaching theory for public health nurses (PHNs) who are engaged in Japan's long-term care prevention program. The participants in this study included 112 PHNs and 266 service users who met with these PHNs in order to create a customized care plan within one month after the PHNs' training. The participants were divided into three groups: a supervised group in which the PHNs attended the 1-day training seminar and the follow-up supervision; a seminar group attended only the 1-day training seminar; a control group. The PHNs' sense of performance expectancy, and user's satisfaction, user's spontaneous behavior were evaluated at the baseline (T1), at one month (T2), and at three months (T3) after the PHNs' training. At T3, the PHNs performed a recalled evaluation (RE) of their communication skills before the training. The PHNs' sense of performance expectancy increased significantly over time in the supervised group and the control group (F = 11.28, P < 0.001; F = 4.03, P < 0.05, resp.). The difference score between T3-RE was significantly higher in the supervised group than the control group (P < 0.01). No significant differences in the users' outcomes were found.

Although intensity-modulated radiotherapy (IMRT) may increase the therapeutic ratio of radiotherapy for a range of malignancies, only a few IMRT treatments have yet been performed in the Nordic countries. The scores derived from a national survey to assess Norwegian oncologists' expectations of IMRT are presented. A questionnaire was distributed to all consultants in oncology at Norwegian radiotherapy clinics. Summary scores of daily general radiotherapy workload (DGRTW), acquaintance with IMRT (AI) and expectations of IMRT (EI) were derived. Thirty-nine questionnaires (67%) were returned from a total of 58 oncologists. The oncologists' scores on the AI scale (mean score: 7.5 out of 21) were rather low. Their AI scores were found to be positively correlated with their DGRTW. Higher scores on the EI scale were documented (mean score: 6.2 out of 14): 15 oncologists (39%) rated IMRT as one of the three major contributors to potentially increased cancer survival. Oncologists treating patients with prostate, head and neck, gastrointestinal and CNS tumours had higher EI scores than the other oncologists (7.7 vs. 5.1; p=0.01). The Norwegian radiation oncologists' expectations of IMRT are high in terms of both the potential clinical benefit and the rate of implementation. This should encourage the radiotherapy communities to continue (or rapidly initiate) their efforts in providing the routines required for safe implementation of IMRT

Measuring Provider Performance for Physicians Participating in the Merit-Based Incentive Payment System.

Squitieri, Lee; Chung, Kevin C

2017-07-01

In 2017, the Centers for Medicare and Medicaid Services began requiring all eligible providers to participate in the Quality Payment Program or face financial reimbursement penalty. The Quality Payment Program outlines two paths for provider participation: the Merit-Based Incentive Payment System and Advanced Alternative Payment Models. For the first performance period beginning in January of 2017, the Centers for Medicare and Medicaid Services estimates that approximately 83 to 90 percent of eligible providers will not qualify for participation in an Advanced Alternative Payment Model and therefore must participate in the Merit-Based Incentive Payment System program. The Merit-Based Incentive Payment System path replaces existing quality-reporting programs and adds several new measures to evaluate providers using four categories of data: (1) quality, (2) cost/resource use, (3) improvement activities, and (4) advancing care information. These categories will be combined to calculate a weighted composite score for each provider or provider group. Composite Merit-Based Incentive Payment System scores based on 2017 performance data will be used to adjust reimbursed payment in 2019. In this article, the authors provide relevant background for understanding value-based provider performance measurement. The authors also discuss Merit-Based Incentive Payment System reporting requirements and scoring methodology to provide plastic surgeons with the necessary information to critically evaluate their own practice capabilities in the context of current performance metrics under the Quality Payment Program.

Cancer quality registers are attracting increasing attention as important, but still underutilized sources of clinical data. To optimize the use of registers in quality assurance and improvement, data have to be rapidly collected, collated and presented as actionable, at-a-glance information to the reporting departments. This article presents a dashboard performance report on select quality indicators to cancer care providers. Ten quality indicators registered on an individual patient level in the National Prostate Cancer Register of Sweden and recommended by the National Prostate Cancer Guidelines were selected. Data reported to the National Prostate Cancer Register are uploaded within 24 h to the Information Network for Cancer Care platform. Launched in 2014, "What''s Going On, Prostate Cancer" provides rapid, at-a-glance performance feedback to care providers. The indicators include time to report to the National Prostate Cancer Register, waiting times, designated clinical nurse specialist, multidisciplinary conference, adherence to guidelines for diagnostic work-up and treatment, and documentation and outcome of treatment. For each indicator, three performance levels were defined. What's Going On, a dashboard performance report on 10 selected quality indicators to cancer care providers, provides an example of how data in cancer quality registers can be transformed into condensed, at-a-glance information to be used as actionable metrics for quality assurance and improvement.

Stochastic Dominance under the Nonlinear Expected Utilities

Xinling Xiao

2014-01-01

Full Text Available In 1947, von Neumann and Morgenstern introduced the well-known expected utility and the related axiomatic system (see von Neumann and Morgenstern (1953. It is widely used in economics, for example, financial economics. But the well-known Allais paradox (see Allais (1979 shows that the linear expected utility has some limitations sometimes. Because of this, Peng proposed a concept of nonlinear expected utility (see Peng (2005. In this paper we propose a concept of stochastic dominance under the nonlinear expected utilities. We give sufficient conditions on which a random choice X stochastically dominates a random choice Y under the nonlinear expected utilities. We also provide sufficient conditions on which a random choice X strictly stochastically dominates a random choice Y under the sublinear expected utilities.

Costs and Performance of English Mental Health Providers.

Moran, Valerie; Jacobs, Rowena

Despite limited resources in mental health care, there is little research exploring variations in cost performance across mental health care providers. In England, a prospective payment system for mental health care based on patient needs has been introduced with the potential to incentivise providers to control costs. The units of payment under the new system are 21 care clusters. Patients are allocated to a cluster by clinicians, and each cluster has a maximum review period. The aim of this research is to explain variations in cluster costs between mental health providers using observable patient demographic, need, social and treatment variables. We also investigate if provider-level variables explain differences in costs. The residual variation in cluster costs is compared across providers to provide insights into which providers may gain or lose under the new financial regime. The main data source is the Mental Health Minimum Data Set (MHMDS) for England for the years 2011/12 and 2012/13. Our unit of observation is the period of time spent in a care cluster and costs associated with the cluster review period are calculated from NHS Reference Cost data. Costs are modelled using multi-level log-linear and generalised linear models. The residual variation in costs at the provider level is quantified using Empirical Bayes estimates and comparative standard errors used to rank and compare providers. There are wide variations in costs across providers. We find that variables associated with higher costs include older age, black ethnicity, admission under the Mental Health Act, and higher need as reflected in the care clusters. Provider type, size, occupancy and the proportion of formal admissions at the provider-level are also found to be significantly associated with costs. After controlling for patient- and provider-level variables, significant residual variation in costs remains at the provider level. The results suggest that some providers may have to increase

Stochastic samples versus vacuum expectation values in cosmology

2010-01-01

Particle theorists typically use expectation values to study the quantum back-reaction on inflation, whereas many cosmologists stress the stochastic nature of the process. While expectation values certainly give misleading results for some things, such as the stress tensor, we argue that operators exist for which there is no essential problem. We quantify this by examining the stochastic properties of a noninteracting, massless, minimally coupled scalar on a locally de Sitter background. The square of the stochastic realization of this field seems to provide an example of great relevance for which expectation values are not misleading. We also examine the frequently expressed concern that significant back-reaction from expectation values necessarily implies large stochastic fluctuations between nearby spatial points. Rather than viewing the stochastic formalism in opposition to expectation values, we argue that it provides a marvelously simple way of capturing the leading infrared logarithm corrections to the latter, as advocated by Starobinsky

Full Text Available This paper proposes a probability model to explore the dynamic process of customer’s satisfaction. Bases on expectation disconfirmation theory, the satisfaction is constructed with customer’s expectation before buying behavior and the perceived performance after purchase. The experiment method is designed to measure expectation disconfirmation effects and we also use the collection data to estimate the overall satisfaction and model calibration. The results show good fitness between the model and the real data. This model has application for business marketing areas in order to manage relationship satisfaction.

2016-03-01

This project used a nonexperimental design with a convenience sample and studied the relationship between academic motivation, grade expectation, and academic performance in 1,210 students enrolled in undergraduate human anatomy and physiology (HAP) classes over a 2-yr period. A 42-item survey that included 28 items of the adapted academic motivation scale for HAP based on self-determination theory was administered in class during the first 3 wk of each semester. Students with higher grade point averages, who studied for longer hours and reported to be more motivated to succeed, did better academically in these classes. There was a significant relationship between students' scores on the adapted academic motivation scale and performance. Students were more extrinsically motivated to succeed in HAP courses than intrinsically motivated to succeed, and the analyses revealed that the most significant predictor of final grade was within the extrinsic scale (introjected and external types). Students' motivations remained stable throughout the course sequence. The data showed a significant relationship between HAP students' expected grade and their final grade in class. Finally, 65.5% of students overestimated their final grade, with 29% of students overestimating by two to four letter grades. Copyright © 2016 The American Physiological Society.

Should providers encourage realistic weight expectations and satisfaction with lost weight in commercial weight loss programs? a preliminary study.

Ames, Gretchen E; Thomas, Colleen S; Patel, Roshni H; McMullen, Jillian S; Lutes, Lesley D

2014-01-01

Attrition is a problem among patients who participate in commercial weight loss programs. One possible explanation is that if patients are unable to reach a weight that they expect to achieve, they may be more likely to drop out of treatment. This study investigated variables associated with attrition among 30 obese patients who completed a liquid meal replacement program (LMR) and enrolled in a 52-week Small Changes Maintenance intervention (SCM). Patients lost a median 18% of body weight during LMR and completed assessments about weight expectations and weight satisfaction pre- and post-SCM. Of the 30 patients who started SCM, 8 (27%) were lost to attrition. Odds of SCM attrition were higher in patients who lost ≤ 18.2% of pre-LMR weight (OR: 12.25, P = 0.035), had lower satisfaction (≤7) pre-SCM (OR: 10.11, P = 0.040), and who expected further weight loss of 9.1 kg or more pre-SCM (OR: 10.11, P = 0.040). SCM completers significantly increased weight loss expectations by a median of 2.3 kg from pre-SCM to post-SCM (WSR P = 0.049) that paralleled weight regained post-SCM (2.7 kg). After completion of a medically-supervised commercial weight loss program, patients with the greatest expectations for further weight loss and the lowest weight satisfaction were more likely to drop out of SCM. Failure to participate in maintenance treatment may lead to regain of greater than half of lost weight over the next year. Among SCM completers, lower expectations for further weight loss and greater weight satisfaction appeared to be associated with continued engagement in maintenance treatment.

Ethical issues and societal expectations

International Nuclear Information System (INIS)

Metlay, D.

2010-01-01

Daniel Metlay (NWTRB) declared that institutions had always recognised an ethical obligation to manage high- level radioactive waste in unprecedented ways. This obligation has not only endured, but has become more explicit and multidimensional and it now subsumed under a more general rubric of 'societal expectations'. D. Metlay directed attention toward the proceedings of previous RWMC-RF workshop ', which contains five essays, authored by Kjell Andersson, Andrew Blowers, Carl-Reinhold Braakenhielm, Francois Dermange, and Patricia Fleming, that are relevant to the question of ethical issues and societal expectations. D. Metlay observed that 'societal expectations' are hard to define and thus very hard to measure. They may vary considerably with time and from country to country. As an illustration he referred to an inquiry performed by a task group 30 years ago in a document entitled 'Proposed Goals for Radioactive Waste Management' (NUREG-0300) on behalf of the U.S. Nuclear Regulatory Commission. Conclusions from D. Metlay are that, for the most part, societal expectations in the United States appear to be quite stable over a period of more than 30 years. In two areas, however, there are clear differences in emphasis between expectations articulated in the last few years and those recorded in 1978. (1) While then there was emphasis on the operational reliability of organisations and institutions. In particular, much care was taken to discuss the inherent limitations on bureaucratic error-correction in the future. The focus is nowadays more on bureaucratic behaviours associated with carrying out decision-making processes in the present. (2) While there is current emphasis on the importance of trust, transparency, and accountability, the NRC document may cast some doubt on the reliability of a stepwise decision-making process. In the domain of radioactive waste management, error signals are notoriously unclear, and strong disagreements over objectives and value trade

Expected value information improves financial risk taking across the adult life span.

When making decisions, individuals must often compensate for cognitive limitations, particularly in the face of advanced age. Recent findings suggest that age-related variability in striatal activity may increase financial risk-taking mistakes in older adults. In two studies, we sought to further characterize neural contributions to optimal financial risk taking and to determine whether decision aids could improve financial risk taking. In Study 1, neuroimaging analyses revealed that individuals whose mesolimbic activation correlated with the expected value estimates of a rational actor made more optimal financial decisions. In Study 2, presentation of expected value information improved decision making in both younger and older adults, but the addition of a distracting secondary task had little impact on decision quality. Remarkably, provision of expected value information improved the performance of older adults to match that of younger adults at baseline. These findings are consistent with the notion that mesolimbic circuits play a critical role in optimal choice, and imply that providing simplified information about expected value may improve financial risk taking across the adult life span.

Paying for performance provides financial rewards to medical care providers for improvements in performance measured by utilization and quality of care indicators. In 2006, Rwanda began a pay for performance scheme to improve health services delivery, including HIV/AIDS services. Using a prospective quasi-experimental design, this study examines the scheme's impact on individual and couples HIV testing. We find a positive impact of pay for performance on HIV testing among married individuals (10.2 percentage points increase). Paying for performance also increased testing by both partners by 14.7 percentage point among discordant couples in which only one of the partners is an AIDS patient. Copyright © 2014.

Predicting problem behaviors with multiple expectancies: expanding expectancy-value theory.

Borders, Ashley; Earleywine, Mitchell; Huey, Stanley J

2004-01-01

Expectancy-value theory emphasizes the importance of outcome expectancies for behavioral decisions, but most tests of the theory focus on a single behavior and a single expectancy. However, the matching law suggests that individuals consider expected outcomes for both the target behavior and alternative behaviors when making decisions. In this study, we expanded expectancy-value theory to evaluate the contributions of two competing expectancies to adolescent behavior problems. One hundred twenty-one high school students completed measures of behavior problems, expectancies for both acting out and academic effort, and perceived academic competence. Students' self-reported behavior problems covaried mostly with perceived competence and academic expectancies and only nominally with problem behavior expectancies. We suggest that behavior problems may result from students perceiving a lack of valued or feasible alternative behaviors, such as studying. We discuss implications for interventions and suggest that future research continue to investigate the contribution of alternative expectancies to behavioral decisions.

Prospective association of peer influence, school engagement, drinking expectancies, and parent expectations with drinking initiation among sixth graders.

Early initiation of drinking increases the lifetime risk for substance abuse and other serious health and social problems. An understanding of the predictors of early initiation is needed if successful preventive interventions are to be developed. Surveys were completed by 1009 sixth grade students at the beginning (Time 1) and end (Time 2) of the school year in four schools in one suburban school district. At Time 1, 55/1009 (5.5%) reported drinking in the past 30 days. From Time 1 to Time 2, the percentage of drinkers increase to 127/1009 (10.9%) of whom 101 were new drinkers. In multiple logistic regression analyses, school engagement was negatively associated and peer influence and drinking expectancies were positively associated with drinking initiation. A significant interaction was found between drinking expectancies and parental expectations. Among sixth graders with high drinking expectancies, those with low parental expectations for their behavior were 2.6 times more likely to start drinking than those with parents with high expectations for their behavior. Positive drinking expectancies were significantly associated with drinking initiation only among teens who believed their parents did not hold strong expectations for them not to drink. This finding held for boys and girls, Blacks and Whites and was particularly strong for Black youth. This finding provides new information about the moderating effect of parental expectations on drinking expectancies among early adolescents.

Attention directed by expectations enhances receptive fields in cortical area MT.

Expectations, especially those formed on the basis of extensive training, can substantially enhance visual performance. However, it is not clear that the physiological mechanisms underlying this enhancement are identical to those examined by experiments in which attention is directed by explicit instructions rather than strong expectations. To study the changes in visual representations associated with strong expectations, we trained animals to detect a brief motion pulse that was embedded in noise. Because the nature of the pulse and the statistics of its appearance were well known to the animals, they formed strong expectations which determined their behavioral performance. We used white-noise methods to infer the receptive field structure of single neurons in area MT while they were performing this task. Incorporating non-linearities, we compared receptive fields during periods of time when the animals were expecting the motion pulse with periods of time when they were not. We found receptive field changes consistent with an increased reliability in signaling pulse occurrence. Moreover, these changes were not consistent with a simple gain modulation. The results suggest that strong expectations can create very specific changes in the visual representations at a cellular level to enhance performance. Copyright 2009 Elsevier Ltd.

Neural representation of expected value in the adolescent brain.

Science.gov (United States)

Barkley-Levenson, Emily; Galván, Adriana

2014-01-28

Previous work shows that the adolescent reward system is hyperactive, but this finding may be confounded by differences in how teens value money. To address this, we examined the neural ontogeny of objective value representation. Adolescent and adult participants performed a monetary gambling task in which they chose to accept or reject gambles of varying expected value. Increasing expected value had a stronger influence over gambling choices in adolescents relative to adults, an effect that was paralleled by greater activation in the ventral striatum in adolescents. This unique adolescent ventral striatum response remained even after matching groups on acceptance behavior. These behavioral and neural data suggest that the value of available options has a greater influence in adolescent versus adult choices, even when objective value and subjective choice are held constant. This research provides further evidence that hyperactivation of reward circuitry in adolescence may be a normative ontogenetic shift that is due to greater valuation in the adolescent brain.

Clinical performance measurement has been a key element of efforts to transform the Veterans Health Administration (VHA). However, there are a number of signs that current performance measurement systems used within and outside the VHA may be reaching the point of maximum benefit to care and in some settings, may be resulting in negative consequences to care, including overtreatment and diminished attention to patient needs and preferences. Our research group has been involved in a long-standing partnership with the office responsible for clinical performance measurement in the VHA to understand and develop potential strategies to mitigate the unintended consequences of measurement. Our aim was to understand how the implementation of diabetes performance measures (PMs) influences management actions and day-to-day clinical practice. This is a mixed methods study design based on quantitative administrative data to select study facilities and quantitative data from semi-structured interviews. Sixty-two network-level and facility-level executives, managers, front-line providers and staff participated in the study. Qualitative content analyses were guided by a team-based consensus approach using verbatim interview transcripts. A published interpretive motivation theory framework is used to describe potential contributions of local implementation strategies to unintended consequences of PMs. Implementation strategies used by management affect providers' response to PMs, which in turn potentially undermines provision of high-quality patient-centered care. These include: 1) feedback reports to providers that are dissociated from a realistic capability to address performance gaps; 2) evaluative criteria set by managers that are at odds with patient-centered care; and 3) pressure created by managers' narrow focus on gaps in PMs that is viewed as more punitive than motivating. Next steps include working with VHA leaders to develop and test implementation approaches to help

The chirally rotated Schroedinger functional. Theoretical expectations and perturbative tests

International Nuclear Information System (INIS)

Dalla Brida, Mattia

2016-03-01

The chirally rotated Schroedinger functional (χSF) with massless Wilson-type fermions provides an alternative lattice regularization of the Schroedinger functional (SF), with different lattice symmetries and a common continuum limit expected from universality. The explicit breaking of flavour and parity symmetries needs to be repaired by tuning the bare fermion mass and the coefficient of a dimension 3 boundary counterterm. Once this is achieved one expects the mechanism of automatic O(a) improvement to be operational in the χSF, in contrast to the standard formulation of the SF. This is expected to significantly improve the attainable precision for step-scaling functions of some composite operators. Furthermore, the χSF offers new strategies to determine finite renormalization constants which are traditionally obtained from chiral Ward identities. In this paper we consider a complete set of fermion bilinear operators, define corresponding correlation functions and explain the relation to their standard SF counterparts. We discuss renormalization and O(a) improvement and then use this set-up to formulate the theoretical expectations which follow from universality. Expanding the correlation functions to one-loop order of perturbation theory we then perform a number of non-trivial checks. In the process we obtain the action counterterm coefficients to one-loop order and reproduce some known perturbative results for renormalization constants of fermion bilinears. By confirming the theoretical expectations, this perturbative study lends further support to the soundness of the χSF framework and prepares the ground for non-perturbative applications.

Point and interval forecasts of mortality rates and life expectancy: A comparison of ten principal component methods

Directory of Open Access Journals (Sweden)

Han Lin Shang

2011-07-01

Full Text Available Using the age- and sex-specific data of 14 developed countries, we compare the point and interval forecast accuracy and bias of ten principal component methods for forecasting mortality rates and life expectancy. The ten methods are variants and extensions of the Lee-Carter method. Based on one-step forecast errors, the weighted Hyndman-Ullah method provides the most accurate point forecasts of mortality rates and the Lee-Miller method is the least biased. For the accuracy and bias of life expectancy, the weighted Hyndman-Ullah method performs the best for female mortality and the Lee-Miller method for male mortality. While all methods underestimate variability in mortality rates, the more complex Hyndman-Ullah methods are more accurate than the simpler methods. The weighted Hyndman-Ullah method provides the most accurate interval forecasts for mortality rates, while the robust Hyndman-Ullah method provides the best interval forecast accuracy for life expectancy.

The objective of this study was to assess the number and magnitude of preoperative expectations and to correlate them with the degree of satisfaction expressed one year after Total Hip Arthroplasty (THA) or Total Knee Arthroplasty (TKA), in patients with severe and painful osteoarthritis (OA). Preoperative expectations (within 20 days prior to surgery) and postoperative satisfaction (one year after the intervention) were measured using the previously validated French version of the Hospital for Special Surgery Hip or Knee Replacement Expectations Survey. Postoperative satisfaction was measured using a specific scale, following the same methodology as that used for the assessment of expectations. Prediction of the satisfaction of the patients was performed using multivariate linear regression modelling. A total of 138 patients (80 THA and 58 TKA) completed the two parts of the study. The expectations score (mean ± SD) (range 0-100) was 72.58 ± 12.63 before THA and 69.10 ± 13.72 before TKA (p = 0.13). The number of expectations expressed was 14.34 ± 1.32 (out of a potential maximum of 18) before THA and 14.70 ± 2.29 (out of a potential maximum of 19) before TKA. After 1 year, THA generated a significantly higher degree of satisfaction compared to TKA (69.70 ± 14.46 v 60.44 ± 17.54, poptimal preoperative interaction between health care providers and patients, to allow patients a chance to foresee a reasonable outcome after TJA.

Prediction Interval: What to Expect When You're Expecting … A Replication.

Directory of Open Access Journals (Sweden)

Jeffrey R Spence

Full Text Available A challenge when interpreting replications is determining whether the results of a replication "successfully" replicate the original study. Looking for consistency between two studies is challenging because individual studies are susceptible to many sources of error that can cause study results to deviate from each other and the population effect in unpredictable directions and magnitudes. In the current paper, we derive methods to compute a prediction interval, a range of results that can be expected in a replication due to chance (i.e., sampling error, for means and commonly used indexes of effect size: correlations and d-values. The prediction interval is calculable based on objective study characteristics (i.e., effect size of the original study and sample sizes of the original study and planned replication even when sample sizes across studies are unequal. The prediction interval provides an a priori method for assessing if the difference between an original and replication result is consistent with what can be expected due to sample error alone. We provide open-source software tools that allow researchers, reviewers, replicators, and editors to easily calculate prediction intervals.

Theory suggests that the accuracy of metacognitive monitoring is affected by the cues used to judge learning. Researchers have improved monitoring accuracy by directing attention to more appropriate cues; however, this is the first study to more directly point students to more appropriate cues using instructions regarding tests and practice tests. The purpose of the present study was to examine whether the accuracy metacognitive monitoring was affected by the nature of the test expected. Students (N= 59) were randomly assigned to one of two test expectancy groups (memory vs. inference). Then after reading texts, judging learning, completed both memory and inference tests. Test performance and monitoring accuracy were superior when students received the kind of test they had been led to expect rather than the unexpected test. Tests influence students' perceptions of what constitutes learning. Our findings suggest that this could affect how students prepare for tests and how they monitoring their own learning. ©2010 The British Psychological Society.

The role of expectations in patients' hospital assessments: a Turkish university hospital example.

Bakar, Coskun; Akgün, H Seval; Al Assaf, A F

2008-01-01

This paper aims to conduct a preliminary assessment of patient attitudes regarding important aspects of service dimensions using SERVQUAL. The SERVQUAL scale is routinely used at the Baskent University Hospitals Network, Turkey. The study consisted of 550 randomly chosen patients who presented to any member of the hospital network during January and February 2006 and received treatment as inpatients or outpatients at those healthcare facilities. The patients' perceived scores were higher than expected for an ordinary hospital but lower than expected for a high-quality hospital. Young patients had a high-expected service score gap and a low adequate service score difference. Highly educated patients had a high-expected service score difference. Uninsured patients had a low adequate service score difference. Baskent University multidisciplinary healthcare teams have performed periodic patient satisfaction surveys in order to identify strengths and problem areas, formulate the quality improvement objectives and monitor progress towards achieving these objectives. However, patient satisfaction survey results are often highly positive. In these cases, improving care is not easy because measures are not sensitive enough to changes. Therefore a more sensitive measurement tool based on the SERVQUAL scale was developed. The authors believe that patient opinions are extremely important because they provide information that is not necessarily emphasized by managers or health care professionals, resulting in a more complete assessment of past performance and a clearer road map for future action.

Self-medication is the use of medicines for therapeutic intent without a clinician’s advice or prescription. The National Socioeconomic Survey for Indonesia in 2009 found the percentage of the Indonesians engaging in self-medication is increasing. The objectives of this study were to assess consumers’ expectations regarding service quality provide by pharmacist in self-medication practices and determine the factors associated with self-medication in Bandung, Indonesia. We conduct a cross-sectional survey at eight randomly selected community pharmacies during July-November 2012 and purposely sampled 1,200 costumers purchasing medication at those sites. Subjects reported they understood the information about the medicines given by the pharmacist but still wanted more information and time to consult with the pharmacist about their medicines. Factors associated with self-medication were younger age, male gender, greater education and lower income. The intervention is needed to improve appropriate self-medication.

The vertical emittance minimization campaign at SLS, realized in the context of the TIARA WP6, has already achieved the world's smallest vertical beam size of 3.6 μm, corresponding to a vertical emittance of 0.9 pm, in a synchrotron light source. The minimum value reached for the vertical emittance is only about five times larger than the quantum limit of 0.2 pm. However, the resolution limit of the present SLS emittance monitor has also been reached during this campaign, thus, to further continue the emittance minimization program the construction of an improved second monitor is necessary. In this paper we present the design and studies on the performance of this new monitor based on the image formation method using vertically polarized synchrotron radiation in the visible and UV spectral ranges. This new monitor includes an additional feature, providing the possibility of performing full interferometric measurement by the use of a set of vertical obstacles that can be driven on the light path.

Full Text Available Abstract Background Positive alcohol outcome expectancy has consistently been linked with problematic drinking, but there is little population-based evidence on its role on early stages of drinking in childhood. The present study seeks to understand the extent to which drinking of family members is differentially associated with the endorsement of alcohol expectancy in late childhood. Methods A representative sample of 4th and 6th graders (N = 2455 drawn from 28 public schools in an urban region of Taiwan completed a self-administered paper-and-pencil questionnaire. Each student provided information on alcohol expectancy, drinking experiences, and individual and family attributes. Complex survey analyses were performed to evaluate the relationship, with stratification by children's alcohol drinking history. Results An estimated 29% of the 4th graders and 43% of the 6th graders had initiated alcohol consumption (over 40% of them had drank on three or more occasions. Alcohol drinking-related differences appear in both the endorsement and the correlates of alcohol expectancy. Positive alcohol expectancy was strongly associated with family drinking, particularly the dimension of "enhanced social behaviors"; negative alcohol expectancy was inversely associated with drinking frequency. Among alcohol naïve children, significant connections appear between paternal drinking and three dimensions of positive alcohol expectancy (i.e., enhanced social behaviors:βwt = 0.15, promoting relaxation or tension reduction:βwt = 0.18, and global positive transformation:βwt = 0.22. Conclusions Individual tailored strategies that address family influences on alcohol expectancy may be needed in prevention programs targeting drinking behaviors in children.

Extensive work has been carried out by the U.S. Department of Energy (DOE) in the development of a proposed geologic repository at Yucca Mountain (YM), Nevada, for the disposal of high-level radioactive waste. In support of this development and an associated license application to the U.S. Nuclear Regulatory Commission (NRC), the DOE completed an extensive performance assessment (PA) for the proposed YM repository in 2008. This presentation describes the determination of expected dose to the reasonably maximally exposed individual (RMEI) specified in the NRC regulations for the YM repository for the early waste package (WP) failure scenario class and the early drip shield (DS) failure scenario class in the 2008 YM PA. The following topics are addressed: (i) properties of the early failure scenario classes and the determination of dose and expected dose the RMEI, (ii) expected dose and uncertainty in expected dose to the RMEI from the early WP failure scenario class, (iii) expected dose and uncertainty in expected dose to the RMEI from the early DS failure scenario class, (iv) expected dose and uncertainty in expected dose to the RMEI from the combined early WP and early DS failure scenario class with and without the inclusion of failures resulting from nominal processes, and (v) uncertainty in the occurrence of early failure scenario classes. The present article is part of a special issue of Reliability Engineering and System Safety devoted to the 2008 YM PA; additional articles in the issue describe other aspects of the 2008 YM PA. - Highlights: • Extensive work has been carried out by the U.S. DOE in the development of a proposed geologic repository at Yucca Mountain (YM), Nevada, for the disposal of high-level radioactive waste. • Properties of the early failure scenario classes (i.e. early waste package failure and early drip shield failure) in the 2008 YM performance assessment are described. • Determination of dose, expected dose and expected (mean

Full Text Available Transition from school to university can cause concern for many students. One issue is the gap between students' prior expectations and the realities of university life, which can cause significant distress, poor academic performance and increased drop-out rates if not managed effectively. Research has shown several similarities in the expectations of staff and students in regards to which factors determine academic success, but there is also evidence of dissonance. For example, staff consider independent study and critical evaluation as key factors, whereas students view feedback on drafts of work and support from staff as being most important.

We tested the interactive effect of feedback and reward on visuospatial working memory in children with ADHD. Seventeen boys with ADHD and 17 Normal Control (NC) boys underwent functional magnetic resonance imaging (fMRI) while performing four visuospatial 2-back tasks that required monitoring the spatial location of letters presented on a display. Tasks varied in reward size (large; small) and feedback availability (no-feedback; feedback). While the performance of NC boys was high in all conditions, boys with ADHD exhibited higher performance (similar to those of NC boys) only when they received feedback associated with large-reward. Performance pattern in both groups was mirrored by neural activity in an executive function neural network comprised of few distinct frontal brain regions. Specifically, neural activity in the left and right middle frontal gyri of boys with ADHD became normal-like only when feedback was available, mainly when feedback was associated with large-reward. When feedback was associated with small-reward, or when large-reward was expected but feedback was not available, boys with ADHD exhibited altered neural activity in the medial orbitofrontal cortex and anterior insula. This suggests that contextual support normalizes activity in executive brain regions in children with ADHD, which results in improved working memory. Copyright © 2015 The Authors.

The European Union has in the past ten years frequently emphasised its soft power as its primary currency in international affairs. Yet a systematic analysis of the EU’s foreign policy performance, through the prism of the classic ‘capability-expectations gap’, suggests that soft power in itself...... the gap between the expectations and the capabilities. Rather, soft power, when it is present, widens that gap even further by adding to expectations, thus leading to even greater eventual disillusionment when the EU’s hard power capabilities do not match....

Illusory expectations can affect retrieval-monitoring accuracy.

McDonough, Ian M; Gallo, David A

2012-03-01

The present study investigated how expectations, even when illusory, can affect the accuracy of memory decisions. Participants studied words presented in large or small font for subsequent memory tests. Replicating prior work, judgments of learning indicated that participants expected to remember large words better than small words, even though memory for these words was equivalent on a standard test of recognition memory and subjective judgments. Critically, we also included tests that instructed participants to selectively search memory for either large or small words, thereby allowing different memorial expectations to contribute to performance. On these tests we found reduced false recognition when searching memory for large words relative to small words, such that the size illusion paradoxically affected accuracy measures (d' scores) in the absence of actual memory differences. Additional evidence for the role of illusory expectations was that (a) the accuracy effect was obtained only when participants searched memory for the aspect of the stimuli corresponding to illusory expectations (size instead of color) and (b) the accuracy effect was eliminated on a forced-choice test that prevented the influence of memorial expectations. These findings demonstrate the critical role of memorial expectations in the retrieval-monitoring process. 2012 APA, all rights reserved

Measuring Healthcare Providers' Performances Within Managed Competition Using Multidimensional Quality and Cost Indicators.

Portrait, France R M; van der Galiën, Onno; Van den Berg, Bernard

2016-04-01

The Dutch healthcare system is in transition towards managed competition. In theory, a system of managed competition involves incentives for quality and efficiency of provided care. This is mainly because health insurers contract on behalf of their clients with healthcare providers on, potentially, quality and costs. The paper develops a strategy to comprehensively analyse available multidimensional data on quality and costs to assess and report on the relative performance of healthcare providers within managed competition. We had access to individual information on 2409 clients of 19 Dutch diabetes care groups on a broad range of (outcome and process related) quality and cost indicators. We carried out a cost-consequences analysis and corrected for differences in case mix to reduce incentives for risk selection by healthcare providers. There is substantial heterogeneity between diabetes care groups' performances as measured using multidimensional indicators on quality and costs. Better quality diabetes care can be achieved with lower or higher costs. Routine monitoring using multidimensional data on quality and costs merged at the individual level would allow a systematic and comprehensive analysis of healthcare providers' performances within managed competition.

Opposing effects of expectancy and somatic focus on pain.

Directory of Open Access Journals (Sweden)

Natalie E Johnston

Full Text Available High-pain expectancy increases pain and pain-related brain activity, creating a cycle of psychologically maintained pain. Though these effects are robust, little is known about how expectancy works and what psychological processes either support or mitigate its effects. To address this, we independently manipulated pain expectancy and "top-down" attention to the body, and examined their effects on both a performance-based measure of body-focus and heat-induced pain. Multi-level mediation analyses showed that high-pain expectancy substantially increased pain, replicating previous work. However, attention to the body reduced pain, partially suppressing the effects of expectancy. Furthermore, increased body-focus had larger pain-reducing effects when pain expectancy was high, suggesting that attempts to focus on external distractors are counterproductive in this situation. Overall, the results show that attention to the body cannot explain pain-enhancing expectancy effects, and that focusing on sensory/discriminative aspects of pain might be a useful pain-regulation strategy when severe pain is expected.

(Priced) timed games are two-player quantitative games involving an environment assumed to be completely antogonistic. Classical analysis consists in the synthesis of strategies ensuring safety, time-bounded or cost-bounded reachability objectives. Assuming a randomized environment, the (priced......) timed game essentially defines an infinite-state Markov (reward) decision proces. In this setting the objective is classically to find a strategy that will minimize the expected reachability cost, but with no guarantees on worst-case behaviour. In this paper, we provide efficient methods for computing...... reachability strategies that will both ensure worst case time-bounds as well as provide (near-) minimal expected cost. Our method extends the synthesis algorithms of the synthesis tool Uppaal-Tiga with suitable adapted reinforcement learning techniques, that exhibits several orders of magnitude improvements w...

Accurate expectancies diminish perceptual distraction during visual search

Sy, Jocelyn L.; Guerin, Scott A.; Stegman, Anna; Giesbrecht, Barry

2014-01-01

The load theory of visual attention proposes that efficient selective perceptual processing of task-relevant information during search is determined automatically by the perceptual demands of the display. If the perceptual demands required to process task-relevant information are not enough to consume all available capacity, then the remaining capacity automatically and exhaustively “spills-over” to task-irrelevant information. The spill-over of perceptual processing capacity increases the likelihood that task-irrelevant information will impair performance. In two visual search experiments, we tested the automaticity of the allocation of perceptual processing resources by measuring the extent to which the processing of task-irrelevant distracting stimuli was modulated by both perceptual load and top-down expectations using behavior, functional magnetic resonance imaging, and electrophysiology. Expectations were generated using a trial-by-trial cue that provided information about the likely load of the upcoming visual search task. When the cues were valid, behavioral interference was eliminated and the influence of load on frontoparietal and visual cortical responses was attenuated relative to when the cues were invalid. In conditions in which task-irrelevant information interfered with performance and modulated visual activity, individual differences in mean blood oxygenation level dependent responses measured from the left intraparietal sulcus were negatively correlated with individual differences in the severity of distraction. These results are consistent with the interpretation that a top-down biasing mechanism interacts with perceptual load to support filtering of task-irrelevant information. PMID:24904374

Athletes enter injury rehabilitation with certain expectations about the recovery process, outcomes, and the professional providing treatment. Their expectations influence the effectiveness of the assistance received and affect the overall rehabilitation process. Expectations may vary depending on numerous factors such as sport experience, gender, sport type, and cultural background. Unfortunately, limited information is available on athletes' expectations about sport-injury rehabilitation. To examine possible differences in athletes' expectations about sport-injury rehabilitation based on their country of residence and type of sport (contact vs noncontact). Cross-sectional. Recreational, college, and professional athletes from the US, UK, and Finland were surveyed. Of the 1209 athletes ranging from 12 to 80 y of age (mean 23.46 ± 7.91), 529 US [80%], 253 UK [86%], and 199 Finnish [82%] athletes provided details of their geographical location and were included in the final analyses. The Expectations About Athletic Training (EAAT) questionnaire was used to determine athletes' expectations about personal commitment, facilitative conditions, and the expertise of the sports-medicine professional (SMP). A 3 × 2 MANCOVA revealed significant main effects for country (P = .0001, η p 2 = .055) and sport type (P = .0001, η p 2 = .023). Specifically, US athletes were found to have higher expectations of personal commitment and facilitative conditions than their UK and Finnish counterparts. Athletes participating in contact sports had higher expectations of facilitative conditions and the expertise of the SMP than did athletes participating in noncontact sports. SMPs, especially those in the US, should consider the sport and environment when providing services. In addition, SMPs need to highlight and demonstrate their expertise during the rehabilitation process, especially for those who compete in contact sports.

Colour expectations during object perception are associated with early and late modulations of electrophysiological activity.

Stojanoski, Bobby Boge; Niemeier, Matthias

2015-10-01

It is well known that visual expectation and attention modulate object perception. Yet, the mechanisms underlying these top-down influences are not completely understood. Event-related potentials (ERPs) indicate late contributions of expectations to object processing around the P2 or N2. This is true independent of whether people expect objects (vs. no objects) or specific shapes, hence when expectations pertain to complex visual features. However, object perception can also benefit from expecting colour information, which can facilitate figure/ground segregation. Studies on attention to colour show attention-sensitive modulations of the P1, but are limited to simple transient detection paradigms. The aim of the current study was to examine whether expecting simple features (colour information) during challenging object perception tasks produce early or late ERP modulations. We told participants to expect an object defined by predominantly black or white lines that were embedded in random arrays of distractor lines and then asked them to report the object's shape. Performance was better when colour expectations were met. ERPs revealed early and late phases of modulation. An early modulation at the P1/N1 transition arguably reflected earlier stages of object processing. Later modulations, at the P3, could be consistent with decisional processes. These results provide novel insights into feature-specific contributions of visual expectations to object perception.

Covariance of engineering management characteristics with engineering employee performance

Hesketh, Andrew Arthur

1998-12-01

As business in the 1990's grapples with the impact of continuous improvement and quality to meet market demands, there is an increased need to improve the leadership capabilities of our managers. Engineers have indicated desire for certain managerial characteristics in their leadership but there have been no studies completed that approached the problem of determining what managerial characteristics were best at improving employee performance. This study addressed the idea of identifying certain managerial characteristics that enhance employee performance. In the early 1990's, McDonnell Douglas Aerospace in St. Louis used a forced distribution system and allocated 35% of its employees into a "exceeds expectations" category and 60% into a "meets expectations" category. A twenty-question 5 point Likert scale survey on managerial capabilities was administered to a sample engineering population that also obtained their "expectations" category. A single factor ANOVA on the survey results determined a statistical difference between the "exceeds" and "meets" employees with four of the managerial capability questions. The "exceeds expectations" employee indicated that supervision did a better job of supporting subordinate development, clearly communicating performance expectations, and providing timely performance feedback when compared to the "meets expectations" employee. The "meets expectations" employee felt that their opinions, when different from their supervisor's, were more often ignored when compared to the "exceeds expectations" employee. These four questions relate to two specific managerial characteristics, "gaining (informal) authority and support" or "control" characteristic and "providing assistance and guidance" or "command" characteristic, that can be emphasized in managerial training programs.

By varying the probabilities that a stimulus would appear at particular times after the presentation of a cue and modeling the data by the theory of visual attention (Bundesen, 1990), Vangkilde, Coull, and Bundesen (2012) provided evidence that the speed of encoding a singly presented stimulus...... letter into visual short-term memory (VSTM) is modulated by the observer’s temporal expectations. We extended the investigation from single-stimulus recognition to whole report (Experiment 1) and partial report (Experiment 2). Cue–stimulus foreperiods were distributed geometrically using time steps...... of 500 ms. In high expectancy conditions, the probability that the stimulus would appear on the next time step, given that it had not yet appeared, was high, whereas in low expectancy conditions, the probability was low. The speed of encoding the stimuli into VSTM was higher in the high expectancy...

2017-12-01

Grounded in a theoretical model specific to adoptive parents, we examined the relationship between parental expectations and depressive symptoms across time. Assessments of 129 adoptive parents of 64 children were performed at three time points before and after placement of an adopted child with the family: 4-6 weeks pre-placement and 4-6 weeks and 5-6 months post-placement. Expectations were assessed in four dimensions: expectations of self as parents, of the child, of family and friends, and of society. Depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression scale. Associations between parental expectations and depressive symptoms were analyzed, and longitudinal multilevel modeling was conducted to explore influences on expectations over time. Parental expectations changed from pre- to post-placement. With the exception of expectations of self as parent, adoptive parents' pre-adoption expectations were affirmed in the post-adoption time periods. In each expectation dimension, higher affirmation of expectations was correlated with decreased depressive symptoms before and after placement of a child. While parental expectations are not unique to adoptive parents, the essence and characteristics of certain expectations are unique to these parents. When working with adoptive parents, nurses who care for families should assess expectations both pre- and post-placement with awareness of their relationship to depressive symptoms. © 2017 Wiley Periodicals, Inc.

Expectations of millennial nurse graduates transitioning into practice.

Andrews, Diane Randall

2013-01-01

Identified as Millennials, nurses born after 1980 are anticipated to redefine the employer-employee relationship as one based on the employee's wants and needs. The purpose of this study is to portray the expectations of Millennial student nurses immediately before graduation. Understanding these expectations may provide insight for leaders who are responsible for crafting a successful transition experience. Successful transition and decreased turnover are important elements of cost management for the nursing enterprise. A qualitative descriptive design was used to collect data from 14 students enrolled in a traditional BSN academic nursing program approximately 2 months prior to graduation. Upon completion of private, confidential semistructured interviews, data were transcribed, coded, and analyzed. Demographic data were compiled and interview data summarized according to identified themes. Three overarching themes emerged: the expectation that transition would be stressful, the expectation that there would be a safety net of support, and the expectation to be valued and respected as a professional. Revealing was the expectation of supportive relationships and a collaborative approach to patient care. Failure to meet those expectations may result in turnover as Millennials seek opportunities that meet their expectations.

Over the recent years, neuroimaging studies have investigated the neural mechanisms underlying the influence of expectations on perception. However, it seems equally reasonable to assume that expectations impact cognitive functions. Here we used fMRI to explore the role of expectations on task performance and its underlying neural mechanisms. 43 healthy participants were randomly assigned to two groups. Using verbal instructions, group 1 was led to believe that pain enhances task performance while group 2 was instructed that pain hampers their performance. All participants performed a Rapid-Serial-Visual-Presentation (RSVP) Task (target detection and short-term memory component) with or without concomitant painful heat stimulation during 3T fMRI scanning. As hypothesized, short-term memory performance showed an interaction between painful stimulation and expectation. Positive expectations induced stronger neural activation in the right inferior parietal cortex (IPC) during painful stimulation than negative expectation. Moreover, IPC displayed differential functional coupling with the left inferior occipital cortex under pain as a function of expectancy. Our data show that an individual's expectation can influence cognitive performance in a visual short-term memory task which is associated with activity and connectivity changes in brain areas implicated in attentional processing and task performance.

Ionizing Radiation Environment on the International Space Station: Performance vs. Expectations for Avionics and Material

Koontz, Steven L.; Boeder, Paul A.; Pankop, Courtney; Reddell, Brandon

2005-01-01

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

Classroom interactions: exploring the practices of high- and low-expectation teachers.

Science.gov (United States)

Rubie-Davies, Christine M

2007-06-01

Early research exploring teacher expectations concentrated on the dyadic classroom interactions of teachers with individual students. More recent studies have shown whole class factors to have more significance in portraying teachers' expectations. Recently teachers having high or low expectations for all their students have been identified. The aim of the current investigation was to explore whether the classroom exchanges of high- and low-expectation teachers differed substantially and might be considered a mechanism for teachers' expectations. The participants were 12 primary school teachers from eight schools who had been identified as having expectations for their students' learning that were either significantly above or below the children's achievement level. The teachers formed three groups called high-expectation, low-expectation and average-progress teachers. The participants were observed twice in the academic year during half-hour reading lessons. Two people observed each lesson, one completing a structured observation protocol and the other a running record and audiotape. In contrast to the average progress and low expectation teachers, the high-expectation teachers spent more time providing a framework for students' learning, provided their students with more feedback, questioned their students using more higher-order questions, and managed their students' behaviour more positively. There appear to be important differences in the classroom environments for the students of high-expectation, average-progress and low-expectation teachers. The differences apply to both the instructional and socioemotional environments of the classroom. Such disparities may act as mechanisms for teacher expectation effects.

Setting clear expectations for safety basis development

International Nuclear Information System (INIS)

MORENO, M.R.

2003-01-01

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)

Economic Loan Loss Provision and Expected Loss

Directory of Open Access Journals (Sweden)

Stefan Hlawatsch

2010-10-01

Full Text Available The intention of a loan loss provision is the anticipation of the loan's expected losses by adjusting the book value of the loan. Furthermore, this loan loss provision has to be compared to the expected loss according to Basel II and, in the case of a difference, liable equity has to be adjusted. This however assumes that the loan loss provision and the expected loss are based on a similar economic rationale, which is only valid conditionally in current loan loss provisioning methods according to IFRS. Therefore, differences between loan loss provisions and expected losses should only result from different approaches regarding the parameter estimation within each model and not due to different assumptions regarding the outcome of the model. The provisioning and accounting model developed in this paper overcomes the before-mentioned shortcomings and is consistent with an economic rationale of expected losses. Additionally, this model is based on a close-to-market valuation of the loan that is in favor of the basic idea of IFRS. Suggestions for changes in current accounting and capital requirement rules are provided.

Expected Signal Observability at Future Experiments

CERN Document Server

Bartsch, Valeria

2005-01-01

Several methods to quantify the ''significance'' of an expected signal at future experiments have been used or suggested in literature. In this note, comparisons are presented with a method based on the likelihood ratio of the ''background hypothesis'' and the ''signal-plus-background hypothesis''. A large number of Monte Carlo experiments are performed to investigate the properties of the various methods and to check whether the probability of a background fluctuation having produced the claimed significance of the discovery is properly described. In addition, the best possible separation between the two hypotheses should be provided, in other words, the discovery potential of a future experiment be maximal. Finally, a practical method to apply a likelihood-based definition of the significance is suggested in this note. Signal and background contributions are determined from a likelihoo d fit based on shapes only, and the probability density distributions of the significance thus determined are found to be o...

Simultaneous alcohol and cannabis expectancies predict simultaneous use

Directory of Open Access Journals (Sweden)

Earleywine Mitch

2006-10-01

Full Text Available Abstract Background Simultaneous use of alcohol and cannabis predicts increased negative consequences for users beyond individual or even concurrent use of the two drugs. Given the widespread use of the drugs and common simultaneous consumption, problems unique to simultaneous use may bear important implications for many substance users. Cognitive expectancies offer a template for future drug use behavior based on previous drug experiences, accurately predicting future use and problems. Studies reveal similar mechanisms underlying both alcohol and cannabis expectancies, but little research examines simultaneous expectancies for alcohol and cannabis use. Whereas research has demonstrated unique outcomes associated with simultaneous alcohol and cannabis use, this study hypothesized that unique cognitive expectancies may underlie simultaneous alcohol and cannabis use. Results: This study examined a sample of 2600 (66% male; 34% female Internet survey respondents solicited through advertisements with online cannabis-related organizations. The study employed known measures of drug use and expectancies, as well as a new measure of simultaneous drug use expectancies. Expectancies for simultaneous use of alcohol and cannabis predicted simultaneous use over and above expectancies for each drug individually. Discussion Simultaneous expectancies may provide meaningful information not available with individual drug expectancies. These findings bear potential implications on the assessment and treatment of substance abuse problems, as well as researcher conceptualizations of drug expectancies. Policies directing the treatment of substance abuse and its funding ought to give unique consideration to simultaneous drug use and its cognitive underlying factors.

The aim of the present study was to investigate HCPs' performance regarding women experiencing DV in emergency and maternity wards of hospitals in Isfahan, Iran. The present descriptive, cross-sectional study was conducted among 300 HCPs working in emergency and maternity wards in hospitals in Isfahan. The participants were selected using quota random sampling from February to May 2016. A researcher-made questionnaire containing the five items of HCPs performance regarding DV (assessment, intervention, documentation, reference, and follow-up) was used to collect data. The reliability and validity of the questionnaire were confirmed, and the collected data were analyzed using SPSS software. Cronbach's alpha was used to assess the reliability of the questionnaires. To present a general description of the data (variables, mean, and standard deviation), the table of frequencies was designed. The performance of the participants regarding DV in the assessment (mean = 64.22), intervention (mean = 68.55), and reference stages (mean = 68.32) were average. However, in the documentation (mean = 72.55) and follow-up stages (mean = 23.10), their performance was good and weak respectively (criterion from 100). Based on the results, because of defects in providing services for women experiencing DV, a practical indigenous guideline should be provided to treat and support these women.

To identify patient expectations of clinical decision-making at consultations with their general practitioners for distinct health problems and to determine the patient and general practitioner characteristics related to these expectations, with special focus on gender. We performed a multicenter cross-sectional study in 360 patients who were interviewed at home. Data on patients' sociodemographic, clinical characteristics and satisfaction were gathered. General practitioners supplied information on their gender and postgraduate training in family medicine. A questionnaire was used to collect data on patients' expectations that their general practitioner account of their opinion and on expectations of clinical decision making> at consultations with their general practitioner for five problems or hypothetical clinical scenarios (strong chest pain/cold with fever/abnormal discharge/depression or sadness/severe family problem). Patients were asked to indicate their preference that decisions on diagnosis and treatment be taken by: a) the general practitioner alone; b) the general practitioner, taking account of the patient's opinion; c) the patient, taking account of the general practitioner's opinion and d) the patient alone. A logistic regression was performed for clinical decision-making. The response rate was 90%. The mean age was 47.3 + or - 16.5 years and 51% were female. Patients' expectations that their general practitioner listen, explain and take account of their opinions were higher than their expectations of participating in decision-making, depending on the problem in question: 32% wished to participate in chest pain and 49% in family problems. Women had lower expectations of participating in depression and family problems. Patients with female general practitioners had higher expectations of participating in family problems and colds. Most patients wished to be listened to, informed and taken into account by their general practitioners and, to a lesser

The properties of inflation expectations: Evidence for India

Full Text Available Empirical inferences about particular forms of agents’ inflation expectations are crucial for the conduct of monetary policy. This paper is an attempt to explore the properties of the Reserve Bank of India’s survey data of households’ inflation expectations. The paper shows that survey respondents do not form expectations rationally, regardless of the reference measures of inflation used. Further, results indicate that inflation expectations are formed purely in backward-looking manner, suggesting that the Reserve Bank of India (RBI has a low degree of credibility within the survey respondents. The study then formulates a model to identify individual elements of the backward-looking expectations in the data. The results suggest that the respondents’ short term expectations for WPI inflation are purely naïve type of expectations, only influenced by respondents earlier period expectations. In the case of CPIIW inflation, the results however suggest that the short-term expectations are not purely naïve type, but also contain adaptive as well as a static forms of expectations. This means that respondents consider their previous forecast errors about CPIIW inflation and draw recent price developments in the CPIIW while forming their overall short-term inflation expectations. This finding provides some formal evidence that the CPI based inflation measure is better suited, than WPI inflation, as a nominal anchor in the RBI’s recent transition to inflation targeting regime.

Galárraga, Omar; Bertozzi, Stefano M.

2009-01-01

Objective To analyze stakeholder opinions and expectations of the Global Fund to Fight AIDS, Tuberculosis, and Malaria, and to discuss their potential economic and financial implications. Design The Global Fund commissioned an independent study, the “360° Stakeholder Assessment,” to canvas feedback on the organization’s reputation and performance with an on-line survey of 909 respondents representing major stakeholders worldwide. We created a proxy for expectations based on categorical responses for specific Global Fund attributes’ importance to the stakeholders, and current perceived performance. Methods Using multivariate regression, we analyzed 23 unfulfilled expectations related to: resource mobilization; impact measurement; harmonization and inclusion; effectiveness of the Global Fund partner environment; and portfolio characteristics. The independent variables are personal- and regional-level characteristics that affect expectations. Results The largest unfulfilled expectations relate to: mobilization of private sector resources; efficiency in disbursing funds; and assurance that people affected by the three diseases are reached. Stakeholders involved with the Fund through the Country Coordinating Mechanisms, those working in multilateral organizations, and persons living with HIV are more likely to have unfulfilled expectations. In contrast, higher levels of involvement with the Fund correlate with fulfilled expectations. Stakeholders living in sub-Saharan Africa were less likely to have their expectations met. Conclusions Stakeholders unfulfilled expectations result largely from factors external to them, but also from factors over which they have influence. In particular, attributes related to partnership score poorly even though stakeholders have influence in that area. Joint efforts to address perceived performance gaps may improve future performance, and positively influence investment levels and economic viability. PMID:18664957

Smart, Eric; Nalder, Emily; Rigby, Patty; King, Gillian

2018-04-03

Family-Centered Care (FCC) represents the ideal service delivery approach in pediatric rehabilitation. Nonetheless, implementing FCC as intended in clinical settings continues to be hindered by knowledge gaps. One overlooked gap is our understanding of clients' therapy expectations. This perspective article synthesizes knowledge from the mental health services literature on strategies recommended to service providers for generating transparent and congruent therapy expectations with clients, and applies this knowledge to the pediatric rehabilitation literature, where this topic has been researched significantly less, for the purpose of improving FCC implementation. Dimensions of the Measure of Processes of Care, an assessment tool that measures clients' perceptions of the extent a service is family-centered, inform the organization of therapy expectation-generating strategies: (1) Providing Respectful and Supportive Care (assessing and validating clients' expectations); (2) General and Specific Information (foreshadowing therapy journeys, explaining treatment rationale, and conveying service provider qualifications); (3) Coordinated and Comprehensive Care (socializing clients to roles and reflecting on past socialization); and (4) Enabling and Partnership (applying a negotiation framework and fostering spaces safe to critique). Strategies can help pediatric rehabilitation service providers work with families to reframe unrealistic expectations, establish congruent beliefs supporting effective partnerships, and prevent possible disillusionment with therapy over time.

Learning about Expectation Violation from Prediction Error Paradigms – A Meta-Analysis on Brain Processes Following a Prediction Error

Full Text Available Modifying patients’ expectations by exposing them to expectation violation situations (thus maximizing the difference between the expected and the actual situational outcome is proposed to be a crucial mechanism for therapeutic success for a variety of different mental disorders. However, clinical observations suggest that patients often maintain their expectations regardless of experiences contradicting their expectations. It remains unclear which information processing mechanisms lead to modification or persistence of patients’ expectations. Insight in the processing could be provided by Neuroimaging studies investigating prediction error (PE, i.e., neuronal reactions to non-expected stimuli. Two methods are often used to investigate the PE: (1 paradigms, in which participants passively observe PEs (”passive” paradigms and (2 paradigms, which encourage a behavioral adaptation following a PE (“active” paradigms. These paradigms are similar to the methods used to induce expectation violations in clinical settings: (1 the confrontation with an expectation violation situation and (2 an enhanced confrontation in which the patient actively challenges his expectation. We used this similarity to gain insight in the different neuronal processing of the two PE paradigms. We performed a meta-analysis contrasting neuronal activity of PE paradigms encouraging a behavioral adaptation following a PE and paradigms enforcing passiveness following a PE. We found more neuronal activity in the striatum, the insula and the fusiform gyrus in studies encouraging behavioral adaptation following a PE. Due to the involvement of reward assessment and avoidance learning associated with the striatum and the insula we propose that the deliberate execution of action alternatives following a PE is associated with the integration of new information into previously existing expectations, therefore leading to an expectation change. While further research is needed

The paper studies the relationship between female genital mutilation/cutting (FGM/C) dynamics, social expectations and fundamentals across African countries. We show that socioeconomic conditions are overall worse in countries where FGM/C is practiced. Yet when we consider the dynamics of FGM/C within countries that perform it, there is no clear link between fundamentals and the decline of the practice. We find instead that FGM/C dynamics are strongly related to social expectations and social...

Multiple genetic interaction experiments provide complementary information useful for gene function prediction.

Directory of Open Access Journals (Sweden)

Magali Michaut

Full Text Available Genetic interactions help map biological processes and their functional relationships. A genetic interaction is defined as a deviation from the expected phenotype when combining multiple genetic mutations. In Saccharomyces cerevisiae, most genetic interactions are measured under a single phenotype - growth rate in standard laboratory conditions. Recently genetic interactions have been collected under different phenotypic readouts and experimental conditions. How different are these networks and what can we learn from their differences? We conducted a systematic analysis of quantitative genetic interaction networks in yeast performed under different experimental conditions. We find that networks obtained using different phenotypic readouts, in different conditions and from different laboratories overlap less than expected and provide significant unique information. To exploit this information, we develop a novel method to combine individual genetic interaction data sets and show that the resulting network improves gene function prediction performance, demonstrating that individual networks provide complementary information. Our results support the notion that using diverse phenotypic readouts and experimental conditions will substantially increase the amount of gene function information produced by genetic interaction screens.

The increase in life expectancy and changes in lifestyle have led to prevalence of non-communicable diseases including diabetes whose treatment and care requires effective teamwork. This study was conducted to examine the effect of inter-professional education on performance and diabetes care knowledge of health care teams. This quasi-experimental study was performed as an inter-professional education on 6 healthcare teams (34 people) based on Kolb's Learning Cycle and consisted of a set of training activities to improve individual, group, and inter-professional capabilities of members of the health care team. The pre- and post-tests included Team Climate Inventory (TCI) and a knowledge assessment tool performed before the workshop and 3 months later. Mean scores for knowledge of health care team before intervention and 3 months later were 7.06 ± 1.04 and 7.97 ± 0.97 out of 10, respectively, that showed a significant difference (P teams. It also can make the health-related messages provided to the covered population more consistent in addition to enhancing self-confidence of the personnel.

Does expecting mean achieving? The association between expecting to return to work and recovery in whiplash associated disorders: a population-based prospective cohort study

To determine the association between expectations to return to work and self-assessed recovery. Positive expectations predict better outcomes in many health conditions, but to date the relationship between expecting to return to work after traffic-related whiplash-associated disorders and actual recovery has not been reported. We assessed early expectations for return to work in a cohort of 2,335 individuals with traffic-related whiplash injury to the neck. Using multivariable Cox proportional hazard analysis we assessed the association between return to work expectations and self-perceived recovery during the first year following the event. After adjusting for the effects of sociodemographic characteristics, initial pain and symptoms, post-crash mood, prior health status and collision-related factors, those who expected to return to work reported global recovery 42% more quickly than those who did not have positive expectations (HRR = 1.42, 95% CI 1.26–1.60). Knowledge of return to work expectation provides an important prognostic tool to clinicians for recovery. PMID:19343376

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. Copyright © 2011 Elsevier B.V. All rights reserved.

To determine the willingness to pay (WTP) of senior managers in the UK National Health Service (NHS) for services to help manage performance concerns with doctors, dentists and pharmacists. A discrete choice experiment (DCE) was used to elicit senior managers' preferences for a support service to help manage clinical performance concerns. The DCE was based on: a literature review; interviews with support service providers and clinical professional bodies; and discussion groups with managers. From the DCE responses, we estimate marginal WTP for aspects of support services. 451 NHS managers completed the DCE questionnaire. NHS managers are willing to pay for: advice, 'facilitation', and behavioural, health, clinical and organisational assessments. Telephone advice with written confirmation was valued most highly. NHS managers were willing to pay £161.56 (CI: £160.81-£162.32) per year per whole time equivalent doctor, dentist or pharmacist, for support to help manage clinical performance concerns. Marginal WTP varied across respondent subgroups but was always positive. Health care managers valued help in managing the clinicians' performance, and were willing to pay for it from their organisations' limited funds. Their WTP exceeds the current cost of a UK body providing similar support. Establishing a central body to provide such services across a health care system, with the associated economies of scale including cumulative experience, is an option that policy makers should consider seriously.

Digital model-based engineering (DMbE) is the use of digital artifacts, digital environments, and digital tools in the performance of engineering functions. DMbE is intended to allow an organization to progress from documentation-based engineering methods to digital methods that may provide greater flexibility, agility, and efficiency. The term 'DMbE' was developed as part of an effort by the Model-Based Systems Engineering (MBSE) Infusion Task team to identify what government organizations might expect in the course of moving to or infusing MBSE into their organizations. The Task team was established by the Interagency Working Group on Engineering Complex Systems, an informal collaboration among government systems engineering organizations. This Technical Memorandum (TM) discusses the work of the MBSE Infusion Task team to date. The Task team identified prerequisites, expectations, initial challenges, and recommendations for areas of study to pursue, as well as examples of efforts already in progress. The team identified the following five expectations associated with DMbE infusion, discussed further in this TM: (1) Informed decision making through increased transparency, and greater insight. (2) Enhanced communication. (3) Increased understanding for greater flexibility/adaptability in design. (4) Increased confidence that the capability will perform as expected. (5) Increased efficiency. The team identified the following seven challenges an organization might encounter when looking to infuse DMbE: (1) Assessing value added to the organization. Not all DMbE practices will be applicable to every situation in every organization, and not all implementations will have positive results. (2) Overcoming organizational and cultural hurdles. (3) Adopting contractual practices and technical data management. (4) Redefining configuration management. The DMbE environment changes the range of configuration information to be managed to include performance and design models

The literature demonstrating sex differences in pain is sizable. Most explanations for these differences have focused on biologic mechanisms, and only a few studies have examined social learning. The purpose of this study was to examine the contribution of gender-role stereotypes to sex differences in pain. This study used experimental manipulation of gender-role expectations for men and women. One hundred twenty students participated in the cold pressor task. Before the pain task, participants were given 1 of 3 instructional sets: no expectation, 30-second performance expectation, or a 90-second performance expectation. Pain ratings, threshold, and tolerance were recorded. Significant sex differences in the "no expectation" condition for pain tolerance (t = 2.32, df = 38, P differ in their pain tolerance, pain threshold, or pain ratings. This is the first empirical study to show that manipulation of expectations alters sex differences in laboratory pain.

Adolescent pregnancy: do expectations affect intentions?

To establish the relationship between expectations about the effects of childbearing on specific aspects of life and the strength of the desire to remain nonpregnant during adolescence. We hypothesized that the absence of negative childbearing expectations is associated with an increase in the odds that sexually active, inadequately contracepting teenage girls are cognitively susceptible to conception. A racially and ethnically diverse group of 351 nulligravida, inadequately contracepting teenagers was studied. Participants responded to 60 items that asked about their expectation about the effects of becoming pregnant and not doing so. Analyses were performed to determine the factorial structure of the childbearing expectations items and their relationship to cognitive susceptibility to conception, defined as the lack of desire to remain nonpregnant. The analysis yielded a 9-factor solution for the childbearing expectations items. All 9 sub-scales exhibited acceptable reliability coefficients, stable factor patterns, and correlated significantly with the desire to remain nonpregnant. A dose-dependent relationship suggestive of causality was also apparent. In stepwise regression the sub-scales that assessed the anticipated effect of childbearing on future plans, self-esteem, and boyfriend relations remained significant and accounted for 56% of the variance in the desire to remain nonpregnant. The lengthy research instrument was reduced to an 8-item screening tool without loss of psychometric integrity or explanatory power. Childbearing expectations reflect distinct concepts and account for a significant portion of the variance in the desire to remain nonpregnant during adolescence. Thus the 8-item screening tool we validated might be used to formulate a differential diagnosis for the enigmatic behavior of teens who say they do not "want" to become pregnant but do not "mind" doing so enough to try to avoid conceiving by default.

PROVIDING WOMEN, KEPT MEN

This paper draws on ethnographic and interview based fieldwork to explore accounts of intimate relationships between widowed women and poor young men that emerged in the wake of economic crisis and a devastating HIV epidemic among the Luo ethnic group in Western Kenya. I show how the cooptation of widow inheritance practices in the wake of an overwhelming number of widows as well as economic crisis resulted in widows becoming providing women and poor young men becoming kept men. I illustrate how widows in this setting, by performing a set of practices central to what it meant to be a man in this society – pursuing and providing for their partners - were effectively doing masculinity. I will also show how young men, rather than being feminized by being kept, deployed other sets of practices to prove their masculinity and live in a manner congruent with cultural ideals. I argue that ultimately, women’s practice of masculinity in large part seemed to serve patriarchal ends. It not only facilitated the fulfillment of patriarchal expectations of femininity – to being inherited – but also served, in the end, to provide a material base for young men’s deployment of legitimizing and culturally valued sets of masculine practice.

Wu, Changxu

2018-01-01

Via building computational (typically mathematical and computer simulation) models, human performance modeling (HPM) quantifies, predicts, and maximizes human performance, human-machine system productivity and safety. This paper describes and summarizes the five key questions of human performance modeling: 1) Why we build models of human performance; 2) What the expectations of a good human performance model are; 3) What the procedures and requirements in building and verifying a human performance model are; 4) How we integrate a human performance model with system design; and 5) What the possible future directions of human performance modeling research are. Recent and classic HPM findings are addressed in the five questions to provide new thinking in HPM's motivations, expectations, procedures, system integration and future directions.

Market competition, ownership, payment systems and the performance of health care providers - a panel study among Finnish occupational health services providers.

Many health care reforms rely on competition although health care differs in many respects from the assumptions of perfect competition. Finnish occupational health services provide an opportunity to study empirically competition, ownership and payment systems and the performance of providers. In these markets employers (purchasers) choose the provider and prices are market determined. The price regulation of public providers was abolished in 1995. We had data on providers from 1992, 1995, 1997, 2000 and 2004. The unbalanced panel consisted of 1145 providers and 4059 observations. Our results show that in more competitive markets providers in general offered a higher share of medical care compared to preventive services. The association between unit prices and revenues and market environment varied according to the provider type. For-profit providers had lower prices and revenues in markets with numerous providers. The public providers in more competitive regions were more sensitive to react to the abolishment of their price regulation by raising their prices. Employer governed providers had weaker association between unit prices or revenues and competition. The market share of for-profit providers was negatively associated with productivity, which was the only sign of market spillovers we found in our study.

The chirally rotated Schrödinger functional: theoretical expectations and perturbative tests

International Nuclear Information System (INIS)

Brida, Mattia Dalla; Sint, Stefan; Vilaseca, Pol

2016-01-01

The chirally rotated Schrödinger functional (χSF) with massless Wilson-type fermions provides an alternative lattice regularization of the Schrödinger functional (SF), with different lattice symmetries and a common continuum limit expected from universality. The explicit breaking of flavour and parity symmetries needs to be repaired by tuning the bare fermion mass and the coefficient of a dimension 3 boundary counterterm. Once this is achieved one expects the mechanism of automatic O(a) improvement to be operational in the χSF, in contrast to the standard formulation of the SF. This is expected to significantly improve the attainable precision for step-scaling functions of some composite operators. Furthermore, the χSF offers new strategies to determine finite renormalization constants which are traditionally obtained from chiral Ward identities. In this paper we consider a complete set of fermion bilinear operators, define corresponding correlation functions and explain the relation to their standard SF counterparts. We discuss renormalization and O(a) improvement and then use this set-up to formulate the theoretical expectations which follow from universality. Expanding the correlation functions to one-loop order of perturbation theory we then perform a number of non-trivial checks. In the process we obtain the action counterterm coefficients to one-loop order and reproduce some known perturbative results for renormalization constants of fermion bilinears. By confirming the theoretical expectations, this perturbative study lends further support to the soundness of the χSF framework and prepares the ground for non-perturbative applications.

However, research has shown that expected outcomes causally influence self-efficacy judgments, and some authors have argued that this relationship invalidates self-efficacy theory. Bandura has rebutted those arguments saying that self-efficacy judgments are not invalidated when influenced by expected outcomes. This article focuses on a contradiction in Bandura's rebuttal. Specifically, Bandura has argued (a) expected outcomes cannot causally influence self-efficacy, but (b) self-efficacy judgments remain valid when causally influenced by expected outcomes. While the debate regarding outcome expectancies and self-efficacy has subsided in recent years, the inattention to this contradiction has led to a disproportionate focus on self-efficacy as a causal determinant of behavior at the expense of expected outcomes.

Clustering is an important means of data mining based on separating data categories by similar features. Unlike the classification algorithm, clustering belongs to the unsupervised type of algorithms. Two representatives of the clustering algorithms are the K -means and the expectation maximization (EM) algorithm. Linear regression analysis was extended to the category-type dependent variable, while logistic regression was achieved using a linear combination of independent variables. To predict the possibility of occurrence of an event, a statistical approach is used. However, the classification of all data by means of logistic regression analysis cannot guarantee the accuracy of the results. In this paper, the logistic regression analysis is applied to EM clusters and the K -means clustering method for quality assessment of red wine, and a method is proposed for ensuring the accuracy of the classification results.

WHAT INFLUENCES STUDENTS' EXPECTATIONS IN WHAT REGARDS GRADES?

Directory of Open Access Journals (Sweden)

Mare Codruta

2013-07-01

Full Text Available After a period of studying a certain subject, students form an opinion about it and begin having certain expectations. These expectations and the degree in which, in the end, they fulfil, contribute to the reputation of the university. Consequently, a continuous evaluation of the quality of the educational process is needed. The present research presents a part of a more complex study made on a sample of master students in Audit and Financial Management in Romania. The goal was to evidence the main factors that affect students' expectations in what regards the grades they will obtain at the end of the semester. For this, a questionnaire of 20 questions was applied to 250 such students. After factor reduction procedures were applied, six most significant variables were kept in the analysis: the proportion of knowledge acquired, the perceived level of utility of the discipline in the professional career of the student, the proportion in which the subject could contribute to getting employed in the field it belongs to, the evaluation method and two variables evaluating through grades the didactic performance during the course and the overall performance of the tenure professor. The influence of these variables upon the grade expected by the student was assessed with the help of the OLS regression, both in the simple and multiple forms. Out of the six hypotheses formulated, only one proved to be false based on the simple regression analysis. When individually assessed, the evaluation method announced by the teacher at the beginning of the semester turned out to have no statistically significant influence upon students' expectations. For the rest of the variables, results were according to the assumptions made, i.e. all determine in a significant positive manner the students' opinion about the grade they will get. We have also constructed the multiple regression models. When putting all variables together, the significance changes. The level of

Previous studies suggest that both motivation and task difficulty expectations activate brain regions associated with cognitive control. However, it remains an open question whether motivational and cognitive determinants of control have similar or dissociable impacts on conflict processing on a neural level. The current study tested the effects of motivation and conflict expectancy on activity in regions related to processing of the target and the distractor information. Participants performed a picture-word interference task in which we manipulated the size of performance-dependent monetary rewards (level of motivation) and the ratio of congruent to incongruent trials within a block (level of conflict expectancy). Our results suggest that motivation improves conflict processing by facilitating task-relevant stimulus processing and task difficulty expectations mainly modulate the processing of distractor information. We conclude that motivation and conflict expectancy engage dissociable control strategies during conflict resolution.

Research has shown that patients' expectations of health care and health-care practitioners are complex and may have a significant impact on outcomes of care. Little is known about the expectations of osteopathic patients. To explore osteopathic patients' expectations of private sector care. Focus groups and individual interviews with purposively selected patients; this was the qualitative phase of a mixed methods study, the final phase being a patient survey. A total of 34 adult patients currently attending for treatment at private osteopathic practices across the United Kingdom. Focus group discussions and individual interviews around expectations before, during and after osteopathic care. Thematic analysis of text data to identify topics raised by patients and to group these into broad themes. Many components of expectation were identified. A preliminary conceptual framework describing the way the therapeutic encounter is approached in osteopathy comprised five themes: individual agency, professional expertise, customer experience, therapeutic process and interpersonal relationship. The components of expectation identified in this phase of the study provided potential question topics for the survey questionnaire in the subsequent phase of the investigation. The model developed in this study may add a new perspective to existing evidence on expectations. Further research is recommended to test the findings both within private practice and the National Health Service. © 2013 John Wiley & Sons Ltd.

Service recovery refers to the service provider's response to a dissatisfied customer. This article proposes a model of customer expectations of service recovery in health care services. The model discusses two types of service recovery expectations: will and should. An exploratory study indicates that industry reputation and personal experiences drive customers' "will-expectations" of service recovery while "should-expectations" can be explained via norm, fairness, social contract and hospitality theories.

Maternal Expectations for Toddlers' Reactions to Novelty: Relations of Maternal Internalizing Symptoms and Parenting Dimensions to Expectations and Accuracy of Expectations.

Kiel, Elizabeth J; Buss, Kristin A

2010-07-03

OBJECTIVE: Although maternal internalizing symptoms and parenting dimensions have been linked to reports and perceptions of children's behavior, it remains relatively unknown whether these characteristics relate to expectations or the accuracy of expectations for toddlers' responses to novel situations. DESIGN: A community sample of 117 mother-toddler dyads participated in a laboratory visit and questionnaire completion. At the laboratory, mothers were interviewed about their expectations for their toddlers' behaviors in a variety of novel tasks; toddlers then participated in these activities, and trained coders scored their behaviors. Mothers completed questionnaires assessing demographics, depressive and worry symptoms, and parenting dimensions. RESULTS: Mothers who reported more worry expected their toddlers to display more fearful behavior during the laboratory tasks, but worry did not moderate how accurately maternal expectations predicted toddlers' observed behavior. When also reporting a low level of authoritative-responsive parenting, maternal depressive symptoms moderated the association between maternal expectations and observed toddler behavior, such that, as depressive symptoms increased, maternal expectations related less strongly to toddler behavior. CONCLUSIONS: When mothers were asked about their expectations for their toddlers' behavior in the same novel situations from which experimenters observe this behavior, symptoms and parenting had minimal effect on the accuracy of mothers' expectations. When in the context of low authoritative-responsive parenting, however, depressive symptoms related to less accurate predictions of their toddlers' fearful behavior.

Effective field equations for expectation values

International Nuclear Information System (INIS)

Jordan, R.D.

1986-01-01

We discuss functional methods which allow calculation of expectation values, rather than the usual in-out amplitudes, from a path integral. The technique, based on Schwinger's idea of summing over paths which go from the past to the future and then back to the past, provides effective field equations satisfied by the expectation value of the field. These equations are shown to be real and causal for a general theory up to two-loop order, and unitarity is checked to this order. These methods are applied to a simple quantum-mechanical example to illustrate the differences between the new formalism and the standard theory. When applied to the gravitational field, the new effective field equations should be useful for studies of quantum cosmology

Faulkner, Guy; McCloy, Cora; Plotnikoff, Ronald C; Tremblay, Mark S

2011-07-01

ParticipACTION is a Canadian physical activity communications and social marketing organization that has been relaunched in 2007 after a 6-year hiatus. The purpose of this study is to qualitatively identify and describe the expectations and challenges the relaunch of the new ParticipACTION may present for existing physical activity organizations. Using a purposeful sampling strategy, the authors conduct semistructured telephone interviews with 49 key informants representing a range of national, provincial, and local organizations with a mandate to promote physical activity. Overall, there is strong support in seeing ParticipACTION relaunched. However, organizational expectations and/or their ideal vision for it are mixed. Organizations envision and support its performing an overarching social marketing and advocacy role, and in providing tools and resources that supplement existing organizational activities. Four major organizational challenges are identified concerning overlapping mandates, partnership and leadership concerns, competition for funding, and capacity concerns. Social marketing initiatives, such as ParticipACTION, may not be able to maximize their impact unless they address the expectations and concerns of competing organizations with a mandate to promote physical activity.

To assess the frequency and characteristics of intracranial procedures (ICPs) performed and the number of U.S. residents living with a history of ICP. These data are used to calculate the expected annual number of sporadic Creutzfeldt-Jakob disease (CJD) cases among U.S. residents with a history of ICP. The Nationwide Inpatient Sample provided data on the frequency and types of ICPs, and data from the National Center for Health Statistics was used to produce age-adjusted mortality rates. A model was constructed, which estimated long-term survival and sporadic CJD rates among ICP patients based on procedure type and age. There were an estimated 2,070,488 ICPs in the United States from 1998 to 2007, an average of over 200,000 per year. There were an estimated 2,023,726 U.S. residents in 2013 with a history of ICP in the previous 30 years. In 2013, there was expected to be 4.1 sporadic CJD cases (95% CI 1-8) among people with a history of ICP in the past 30 years. The considerable proportion of U.S. residents living with a history of ICP is important information for retrospective assessments of CJD or any other suspected long-term outcome of ICPs. © 2015 S.

Effect of Prior Cardiopulmonary Resuscitation Knowledge on Compression Performance by Hospital Providers

Directory of Open Access Journals (Sweden)

Joshua N. Burkhardt

2014-07-01

Full Text Available Introduction: The purpose of this study was to determine cardiopulmonary resuscitation (CPR knowledge of hospital providers and whether knowledge affects performance of effective compressions during a simulated cardiac arrest. Methods: This cross-sectional study evaluated the CPR knowledge and performance of medical students and ED personnel with current CPR certification. We collected data regarding compression rate, hand placement, depth, and recoil via a questionnaire to determine knowledge, and then we assessed performance using 60 seconds of compressions on a simulation mannequin. Results: Data from 200 enrollments were analyzed by evaluators blinded to subject knowledge. Regarding knowledge, 94% of participants correctly identified parameters for rate, 58% for hand placement, 74% for depth, and 94% for recoil. Participants identifying an effective rate of ≥100 performed compressions at a significantly higher rate than participants identifying <100 (µ=117 vs. 94, p<0.001. Participants identifying correct hand placement performed significantly more compressions adherent to guidelines than those identifying incorrect placement (µ=86% vs. 72%, p<0.01. No significant differences were found in depth or recoil performance based on knowledge of guidelines. Conclusion: Knowledge of guidelines was variable; however, CPR knowledge significantly impacted certain aspects of performance, namely rate and hand placement, whereas depth and recoil were not affected. Depth of compressions was poor regardless of prior knowledge, and knowledge did not correlate with recoil performance. Overall performance was suboptimal and additional training may be needed to ensure consistent, effective performance and therefore better outcomes after cardiopulmonary arrest.

Expectations from ethics

International Nuclear Information System (INIS)

Fleming, P.

2008-01-01

Prof. Patricia Fleming, centred her presentation on ethical expectations in regulating safety for future generations. The challenge is to find a just solution, one that provides for a defensible approach to inter-generational equity. The question on equity is about whether we are permitted to treat generations differently and to still meet the demands of justice. And the question must be asked regarding these differences: 'in what ways do they make a moral difference?' She asked the question regarding the exact meaning of the ethical principle 'Radioactive waste shall be managed in such a way that predicted impacts on the health of future generations will not be greater than relevant levels of impact that are acceptable today'. Some countries have proposed different standards for different time periods, either implicitly or explicitly. In doing so, have they preserved our standards of justice or have they abandoned them? Prof. Fleming identified six points to provide with some moral maps which might be used to negotiate our way to a just solution to the disposal of nuclear waste. (author)

The mediating role of parental expectations in culture and well-being.

Science.gov (United States)

Oishi, Shigehiro; Sullivan, Helen W

2005-10-01

In two studies, we examined the role of perceived fulfillment of parental expectations in the subjective well-being of college students. In Study 1, we found that American college students reported having higher levels of life satisfaction and self-esteem than did Japanese college students. American college students also reported having fulfilled parental expectations to a greater degree than did Japanese college students. Most importantly, the cultural difference in well-being was mediated by perceived fulfillment of parental expectations. In Study 2, we replicated the mediational finding with Asian American and European American college students. Asian American participants also perceived their parents' expectations about their academic performance to be more specific than did European Americans, which was associated with the cultural difference in perceived fulfillment of parental expectations. In short, perceived parental expectations play an important role in the cultural difference in the well-being of Asians and European Americans.

Using the expected detection delay to assess the performance of different multivariate statistical process monitoring methods for multiplicative and drift faults.

Zhang, Kai; Shardt, Yuri A W; Chen, Zhiwen; Peng, Kaixiang

2017-03-01

Using the expected detection delay (EDD) index to measure the performance of multivariate statistical process monitoring (MSPM) methods for constant additive faults have been recently developed. This paper, based on a statistical investigation of the T 2 - and Q-test statistics, extends the EDD index to the multiplicative and drift fault cases. As well, it is used to assess the performance of common MSPM methods that adopt these two test statistics. Based on how to use the measurement space, these methods can be divided into two groups, those which consider the complete measurement space, for example, principal component analysis-based methods, and those which only consider some subspace that reflects changes in key performance indicators, such as partial least squares-based methods. Furthermore, a generic form for them to use T 2 - and Q-test statistics are given. With the extended EDD index, the performance of these methods to detect drift and multiplicative faults is assessed using both numerical simulations and the Tennessee Eastman process.

Botelho, Ricardo Vieira; Jardim Miranda, Bárbara Cristina; Nishikuni, Koshiro; Waisberg, Jaques

2018-06-01

Life expectancy (LE) refers to the number of years that an individual is expected to survive. Emphasis is frequently placed on the relationship between LE and the conditions under which a population lives, but fewer studies have investigated the relationship between stress factors associated with specific professions and their effects on LE. The aim of this study is to evaluate Brazilian neurosurgeons' life expectancies (BNLEs) and compare them with those of physicians (both Brazilian and foreign) from other fields, as well as with Brazilian nondoctors. The Brazilian Society of Neurosurgery death registry was used to obtain data that compared LEs from non-neurosurgeon physicians, as described in the national and international literature. BNLEs were also compared with the LEs of Brazilian citizens. Fifty-one neurosurgeons died between 2009 and 2016. All were males. The mean age at death was 68.31 ± 17.71 years. Among all-cause mortality, the breakdown was 20% cardiovascular diseases, 39% malignancies, 10% external factors, 6% gastrointestinal disorders, 12% neurologic illnesses, and 14% unknown causes. BNLE was shorter than LE of male Brazilian citizens. LE was similar among neurosurgeons and other doctors but shorter compared with Brazilian citizens. Further research is needed to provide data that can add to and confirm these results. Copyright © 2018 Elsevier Inc. All rights reserved.

Full Text Available Background: Male partners play an important and vital role in the decision-making process regarding pregnant women’s health. The purpose of the present study was to assess the knowledge and awareness of expectant fathers about Gestational Diabetes Mellitus (GDM, Pregnancy Induced Hypertension (PIH, and anaemia during pregnancy. Methods: A cross sectional descriptive study was carried out among expectant fathers whose partners were attending antenatal clinics at the Anuradhapura Teaching Hospital, Sri Lanka. All consenting participants were interviewed by investigators using an interviewer administered questionnaire to collect data on knowledge of risk factors, symptoms, complications and their control. Statistical analysis was performed using the Kruskal Wallis test.  Results: Of the 246 expectant fathers studied, 192 (78% were aware of GDM, 183 (74.4% and 154 (62.6% were aware of PIH and anaemia during pregnancy, respectively. The total number of answers provided by expectant fathers ranged from 0 to 33 (of 41 questions. There were 44 fathers who could not answer even a single question. For GDM, anaemia, and PIH, the percentages of expectant fathers who failed to provide at least a single correct answer were 24.8%, 40.2%, and 31.3%, respectively. The median number of total correct answers provided increased steadily along with the average income (chi-square 31.24, p<0.001 and educational level (chi-square 33.57, p<0.001. Expectant fathers in the 25-34 age group had significantly higher scores, compared to younger and older fathers (chi-square 15.11, p=0.001. Fathers experiencing the second pregnancy of their spouses also had higher scores. Conclusions: Expectant father’s knowledge of the selected morbidities was limited. To improve maternal health, any health promotional programmes should include expectant fathers.

Complementary and alternative medicine (CAM providers’ views of chronic low back pain patients’ expectations of CAM therapies: a qualitative study

Directory of Open Access Journals (Sweden)

Schafer Lisa M

2012-11-01

Full Text Available Abstract Background Some researchers think that patients with higher expectations for CAM therapies experience better outcomes and that enthusiastic providers can enhance treatment outcomes. This is in contrast to evidence suggesting conventional medical providers often reorient patient expectations to better match what providers believe to be realistic. However, there is a paucity of research on CAM providers’ views of their patients’ expectations regarding CAM therapy and the role of these expectations in patient outcomes. Methods To better understand how CAM providers view and respond to their patients’ expectations of a particular therapy, we conducted 32 semi-structured, qualitative interviews with acupuncturists, chiropractors, massage therapists and yoga instructors identified through convenience sampling. Interviews were recorded, transcribed and analyzed thematically using Atlas ti version 6.1. Results CAM providers reported that they attempt to ensure that their patients’ expectations are realistic. Providers indicated they manage their patients’ expectations in a number of domains— roles and responsibilities of providers and patients, treatment outcomes, timeframe for improvement, and treatment experience. Providers reported that patients’ expectations change over time and that they need to continually manage these expectations to enhance patient engagement and satisfaction with treatment. Conclusions Providers of four types of CAM therapies viewed patients’ expectations as an important component of their experiences with CAM therapy and indicated that they try to align patient expectations with reality. These findings suggest that CAM providers are similar in this respect to conventional medical providers.

University-industry coupling: exaggerated expectations

Energy Technology Data Exchange (ETDEWEB)

Roy, R.

This coupling, formally disdainful to university presidents and leading scientists, is now all the rage, according to the author. The presidents' enthusiasm is sparked apparently by hopes of making killings on patents and gaining equity participation in the Silicon Valleys of the future, he notes. The reality of the situation, the cautions, is that all ventures are highly speculative; further, the performance of most universities in knowledge transfer is mixed.

variables that are combined and used to assess the repository performance regarding its emplacement in the transposition zone. Age and lifetime expectancy distributions are solved considering advection and dispersion/diffusion processes according to the approach proposed by Cornaton and Perrochet (2006). Advective-dispersive age solutions are compared to available age dates of pore water within the two main calcareous aquifers (Dogger and Oxfordian) that embed the Callovo-Oxfordian host formation. Such a comparison is helpful for the consolidation of the flow calibration, the estimation of the transport porosity field (since porosity is age generator) and for analyzing the internal water mixing processes and hydraulic behavior of major faults. Lifetime expectancy solutions are used to predict the response at the biosphere resulting from contaminant mass input occurring at a series of hypothetical repository locations. Lifetime expectancy solutions combined with age solutions provide the distribution of total residence times within the domain (i.e the total time required to travel from recharge to discharge). The latter is used to map in the 3-D space the low- and high-speed flow zones at the local scale. Finally, the behavior of age solutions is investigated when the hydraulic regime is rendered transient in response to the climatic evolution during the past Million years and to the climatic projection for the coming Million years. Transient age solutions at actual time are useful to analyze the effect of the temporal flow regime variations on the measured age dates and on ages simulated under steady-flow conditions. (authors)

Impact of Providing Compassion on Job Performance and Mental Health: The Moderating Effect of Interpersonal Relationship Quality.

Science.gov (United States)

Chu, Li-Chuan

2017-07-01

To examine the relationships of providing compassion at work with job performance and mental health, as well as to identify the role of interpersonal relationship quality in moderating these relationships. This study adopted a two-stage survey completed by 235 registered nurses employed by hospitals in Taiwan. All hypotheses were tested using hierarchical regression analyses. The results show that providing compassion is an effective predictor of job performance and mental health, whereas interpersonal relationship quality can moderate the relationships of providing compassion with job performance and mental health. When nurses are frequently willing to listen, understand, and help their suffering colleagues, the enhancement engendered by providing compassion can improve the provider's job performance and mental health. Creating high-quality relationships in the workplace can strengthen the positive benefits of providing compassion. Motivating employees to spontaneously exhibit compassion is crucial to an organization. Hospitals can establish value systems, belief systems, and cultural systems that support a compassionate response to suffering. In addition, nurses can internalize altruistic belief systems into their own personal value systems through a long process of socialization in the workplace. © 2017 Sigma Theta Tau International.

The objective of this study was to examine the source of advanced cancer patients' information about their prognosis and determine whether this source of information could explain racial disparities in the accuracy of patients' life expectancy estimates (LEEs). Coping With Cancer was a prospective, longitudinal, multisite study of terminally ill cancer patients followed until death. In structured interviews, patients reported their LEEs and the sources of these estimates (ie, medical providers, personal beliefs, religious beliefs, and other). The accuracy of LEEs was calculated through a comparison of patients' self-reported LEEs with their actual survival. The sample for this analysis included 229 patients: 31 black patients and 198 white patients. Only 39.30% of the patients estimated their life expectancy within 12 months of their actual survival. Black patients were more likely to have an inaccurate LEE than white patients. A minority of the sample (18.3%) reported that a medical provider was the source of their LEEs; none of the black patients (0%) based their LEEs on a medical provider. Black race remained a significant predictor of an inaccurate LEE, even after the analysis had been controlled for sociodemographic characteristics and the source of LEEs. The majority of advanced cancer patients have an inaccurate understanding of their life expectancy. Black patients with advanced cancer are more likely to have an inaccurate LEE than white patients. Medical providers are not the source of information for LEEs for most advanced cancer patients and especially for black patients. The source of LEEs does not explain racial differences in LEE accuracy. Additional research into the mechanisms underlying racial differences in prognostic understanding is needed.

Full Text Available Measuring the performance of a supply chain is normally of a function of various parameters. Such a problem often involves in a multiple criteria decision making (MCMD problem where different criteria need to be defined and calculated, properly. During the past two decades, Analytical hierarchy procedure (AHP and DEMATEL have been some of the most popular MCDM approaches for prioritizing various attributes. The study of this paper uses a new methodology which is a combination of AHP and DEMATEL to rank various parameters affecting the performance of the supply chain. The DEMATEL is used for understanding the relationship between comparison metrics and AHP is used for the integration to provide a value for the overall performance.

Vrkljan, Sanela; Hendija, Zvjezdana

2016-03-01

Health tourism can be generally divided into medical, health spa and wellness tourism. Health spa tourism services are provided in special hospitals for medical rehabilitation and health resorts, and include under medical supervision controlled use of natural healing factors and physical therapy in order to improve and preserve health. There are 13 special hospitals for medical rehabilitation and health resorts in Croatia. Most of them are financed through the state budget and lesser by sale on the market. More than half of their accommodation capacity is offered for sale on the market while the rest is under contract with the Croatian Health Insurance Fund. Domestic overnights are several times higher than foreign overnights. The aim of this study was to analyze business performance of special hospitals for medical rehabilitation and health resorts in Croatia in relation to the sources of financing and the structure of service users. The assumption was that those who are more market-oriented achieve better business performance. In proving these assumptions, an empirical research was conducted and the assumptions were tested. A positive correlation was proven in tested indicators of business performance of the analyzed service providers of health-spa tourism with a higher amount of overnight stays realized through sales on the market in relation to total overnight stays, with a greater share of foreign overnights in total of overnights and with a higher share of realized revenue on the market out of total revenue. The results of the research show that special hospitals for medical rehabilitation and health resorts that are more market-oriented are more successful in their business performance. These findings are important for planning the health and tourism policies in countries like Croatia.

South Korean alcohol free associations: negative expectancy not predicting drinks per occasion.

2012-06-01

Cultural and biological particulars existing in East Asian countries are likely to mediate differences in the alcohol consumption experience. Despite this no research to date has directly explored the alcohol free association or expectancy of any East Asian nations. The current research aims to provide a set of South Korean alcohol expectancies. Two hundred and thirty-seven South Koreans participated in an alcohol free association test and completed a demographic survey. The results both confirmed and contradicted areas of past alcohol expectancy research. There appears to be differences in associates with high probability of recall and alcohol expectancy, where negative, negative sedating and sedating expectancy categories were not found to be predictors of South Korean drinker level. The results suggest that South Koreans have a more even level of negative expectancy across all drinker categories, possibly due to a combination of linguistic, cultural and biological difference found among this population. The results provide a list of South Korean alcohol free association norms for future alcohol research in the region, with the results also underlining the need for alcohol free association tests among East Asian nations. © 2011 Australasian Professional Society on Alcohol and other Drugs.

Do violations of the axioms of expected utility theory threaten decision analysis?

Science.gov (United States)

Nease, R F

1996-01-01

Research demonstrates that people violate the independence principle of expected utility theory, raising the question of whether expected utility theory is normative for medical decision making. The author provides three arguments that violations of the independence principle are less problematic than they might first appear. First, the independence principle follows from other more fundamental axioms whose appeal may be more readily apparent than that of the independence principle. Second, the axioms need not be descriptive to be normative, and they need not be attractive to all decision makers for expected utility theory to be useful for some. Finally, by providing a metaphor of decision analysis as a conversation between the actual decision maker and a model decision maker, the author argues that expected utility theory need not be purely normative for decision analysis to be useful. In short, violations of the independence principle do not necessarily represent direct violations of the axioms of expected utility theory; behavioral violations of the axioms of expected utility theory do not necessarily imply that decision analysis is not normative; and full normativeness is not necessary for decision analysis to generate valuable insights.

Estimation of expected value for lognormal and gamma distributions

International Nuclear Information System (INIS)

White, G.C.

1978-01-01

Concentrations of environmental pollutants tend to follow positively skewed frequency distributions. Two such density functions are the gamma and lognormal. Minimum variance unbiased estimators of the expected value for both densities are available. The small sample statistical properties of each of these estimators were compared for its own distribution, as well as the other distribution to check the robustness of the estimator. Results indicated that the arithmetic mean provides an unbiased estimator when the underlying density function of the sample is either lognormal or gamma, and that the achieved coverage of the confidence interval is greater than 75 percent for coefficients of variation less than two. Further Monte Carlo simulations were conducted to study the robustness of the above estimators by simulating a lognormal or gamma distribution with the expected value of a particular observation selected from a uniform distribution before the lognormal or gamma observation is generated. Again, the arithmetic mean provides an unbiased estimate of expected value, and the coverage of the confidence interval is greater than 75 percent for coefficients of variation less than two

While many have emphasized impaired reward prediction error signaling in schizophrenia, multiple studies suggest that some decision-making deficits may arise from overreliance on stimulus-response systems together with a compromised ability to represent expected value. Guided by computational frameworks, we formulated and tested two scenarios in which maladaptive representations of expected value should be most evident, thereby delineating conditions that may evoke decision-making impairments in schizophrenia. In a modified reinforcement learning paradigm, 42 medicated people with schizophrenia and 36 healthy volunteers learned to select the most frequently rewarded option in a 75-25 pair: once when presented with a more deterministic (90-10) pair and once when presented with a more probabilistic (60-40) pair. Novel and old combinations of choice options were presented in a subsequent transfer phase. Computational modeling was employed to elucidate contributions from stimulus-response systems (actor-critic) and expected value (Q-learning). People with schizophrenia showed robust performance impairments with increasing value difference between two competing options, which strongly correlated with decreased contributions from expected value-based learning (Q-learning). Moreover, a subtle yet consistent contextual choice bias for the probabilistic 75 option was present in people with schizophrenia, which could be accounted for by a context-dependent reward prediction error in the actor-critic. We provide evidence that decision-making impairments in schizophrenia increase monotonically with demands placed on expected value computations. A contextual choice bias is consistent with overreliance on stimulus-response learning, which may signify a deficit secondary to the maladaptive representation of expected value. These results shed new light on conditions under which decision-making impairments may arise. Copyright © 2018 Society of Biological Psychiatry. Published by

2017-10-01

Despite the high rate of smoking cessation treatment non-response, relatively little empirical work has examined predictors of treatment non-response. The present study sought to explore the effect of smoking outcome expectancies on treatment response in a sample of treatment-seeking adult daily smokers (N=182; 53.3% female; M age =40.67; SD=13.63). Results indicated that expectancies for smoking to reduce negative affect were related to an increased likelihood of treatment non-response (OR=0.73, CI: 0.54, 0.98). These findings remained significant after controlling for sex, presence of Axis I disorder, tobacco-related health problems, tobacco dependence, anxiety sensitivity, and condition assignment as well as other smoking expectancy dimensions. Post hoc analyses revealed that this relation was stronger for smokers in the integrated care condition vs. the standard care condition (Interaction: OR=1.69, CI: 1.05, 2.73). Additionally, expectancies for smoking to enhance positive affect and provide sensory satisfaction were associated with an increased likelihood of treatment response in the standard care condition. The current findings suggest expectancies that smoking will alleviate negative affect may be a risk factor of smoking cessation treatment non-response. Additionally, findings provide evidence that the relation between smoking expectancies and treatment non-response may differ by smoking cessation treatment. Copyright © 2017 Elsevier Ltd.

Full Text Available Expectations towards fitness exercises are the major factor in customer satisfaction in the service sector in question. The purpose of this study is to present a segmentation framework for fitness customers, based on their individual expectations. The survey was designed and validated to evaluate individual expectations towards exercises. The study included a randomly recruited sample of 723 subjects (53% males; 47% females; 42.1±19.7 years. Factor analysis and cluster analysis with Ward’s cluster method with squared Euclidean distance were used to analyse the data obtained. Four components were extracted (performance, enjoyment, beauty and health explaining 68.7% of the total variance and three distinct segments were found: Exercise Lovers (n=312, Disinterested (n=161 and Beauty Seekers (n=250. All the factors identified have a significant contribution to differentiate the clusters, the first and third clusters being most similar. The segmentation framework obtained based on customer expectations allows better understanding of customers’ profiles, thus helping the fitness industry develop services more suitable for each type of customers. A follow-up study was conducted 5 years later and the results concur with the initial study.

A method to derive fixed budget results from expected optimisation times

DEFF Research Database (Denmark)

Doerr, Benjamin; Jansen, Thomas; Witt, Carsten

2013-01-01

At last year's GECCO a novel perspective for theoretical performance analysis of evolutionary algorithms and other randomised search heuristics was introduced that concentrates on the expected function value after a pre-defined number of steps, called budget. This is significantly different from...... the common perspective where the expected optimisation time is analysed. While there is a huge body of work and a large collection of tools for the analysis of the expected optimisation time the new fixed budget perspective introduces new analytical challenges. Here it is shown how results on the expected...... optimisation time that are strengthened by deviation bounds can be systematically turned into fixed budget results. We demonstrate our approach by considering the (1+1) EA on LeadingOnes and significantly improving previous results. We prove that deviating from the expected time by an additive term of ω(n3...

Long, Genia; Mortimer, Richard; Sanzenbacher, Geoffrey

2014-12-01

Abstract Objective: To investigate the evolving use and expected impact of pay-for-performance (P4P) and risk-based provider reimbursement on patient access to innovative medical technology. Structured interviews with leading private payers representing over 110 million commercially-insured lives exploring current and planned use of P4P provider payment models, evidence requirements for technology assessment and new technology coverage, and the evolving relationship between the two topics. Respondents reported rapid increases in the use of P4P and risk-sharing programs, with roughly half of commercial lives affected 3 years ago, just under two-thirds today, and an expected three-quarters in 3 years. All reported well-established systems for evaluating new technology coverage. Five of nine reported becoming more selective in the past 3 years in approving new technologies; four anticipated that in the next 3 years there will be a higher evidence requirement for new technology access. Similarly, four expected it will become more difficult for clinically appropriate but costly technologies to gain coverage. All reported planning to rely more on these types of provider payment incentives to control costs, but didn't see them as a substitute for payer technology reviews and coverage limitations; they each have a role to play. Interviews limited to nine leading payers with models in place; self-reported data. Likely implications include a more uncertain payment environment for providers, and indirectly for innovative medical technology and future investment, greater reliance on quality and financial metrics, and increased evidence requirements for favorable coverage and utilization decisions. Increasing provider financial risk may challenge the traditional technology adoption paradigm, where payers assumed a 'gatekeeping' role and providers a countervailing patient advocacy role with regard to access to new technology. Increased provider financial risk may result in an

Does Physical Activity Increase Life Expectancy? A Review of the Literature

Directory of Open Access Journals (Sweden)

C. D. Reimers

2012-01-01

Full Text Available Physical activity reduces many major mortality risk factors including arterial hypertension, diabetes mellitus type 2, dyslipidemia, coronary heart disease, stroke, and cancer. All-cause mortality is decreased by about 30% to 35% in physically active as compared to inactive subjects. The purpose of this paper was to synthesize the literature on life expectancy in relation to physical activity. A systematic PubMed search on life expectancy in physically active and inactive individuals was performed. In addition, articles comparing life expectancy of athletes compared to that of nonathletes were reviewed. Results of 13 studies describing eight different cohorts suggest that regular physical activity is associated with an increase of life expectancy by 0.4 to 6.9 years. Eleven studies included confounding risk factors for mortality and revealed an increase in life expectancy by 0.4 to 4.2 years with regular physical activity. Eleven case control studies on life expectancy in former athletes revealed consistently greater life expectancy in aerobic endurance athletes but inconsistent results for other athletes. None of these studies considered confounding risk factors for mortality. In conclusion, while regular physical activity increases life expectancy, it remains unclear if high-intensity sports activities further increase life expectancy.

Vacuum expectation value of twist fields

Belitsky, A. V.

2017-09-01

Twist fields emerge in a number of physical applications ranging from entanglement entropy to scattering amplitudes in four-dimensional gauge theories. In this work, their vacuum expectation values are studied in the path integral framework. By performing a gauge transformation, their correlation functions are reduced to field theory of matter fields in external Aharonov-Bohm vortices. The resulting functional determinants are then analyzed within the zeta-function regularization for the spectrum of Bessel zeros, and concise formulas are derived.

Expected number of quantum channels in quantum networks

2015-07-01

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.

Using expectations to monitor robotic progress and recover from problems

Science.gov (United States)

Kurup, Unmesh; Lebiere, Christian; Stentz, Anthony; Hebert, Martial

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.

The healthcare organizations need to develop and implement quality improvement plans for their survival and success. Measuring quality in the healthcare competitive environment is an undeniable necessity for these organizations and will lead to improved patient satisfaction. This study aimed to measure the quality of provided services for patients with chronic kidney disease in Kerman in 2014. This cross-sectional, descriptive-analytic study was performed from 23 January 2014 to 14 February 2014 in four hemodialysis centers in Kerman. All of the patients on chronic hemodialysis (n = 195) who were referred to these four centers were selected and studied using census method. The required data were collected using the SERVQUAL questionnaire, consisting of two parts: questions related to the patients' demographic characteristics, and 28 items to measure the patients' expectations and perceptions of the five dimensions of service quality, including tangibility, reliability, responsiveness, assurance, and empathy. The collected data were analyzed using SPSS 21.0 through some statistical tests, including independent-samples t test, one-way ANOVA, and paired-samples t test. The results showed that the means of patients' expectations were more than their perceptions of the quality of provided services in all dimensions, which indicated that there were gaps in all dimensions. The highest and lowest means of negative gaps were related to empathy (-0.52 ± 0.48) and tangibility (-0.29 ± 0.51). In addition, among the studied patients' demographic characteristics and the five dimensions of service quality, only the difference between the patients' income levels and the gap in assurance were statistically significant (P expectations of patients on hemodialysis were more than their perceptions of provided services. The healthcare providers and employees should pay more attention to the patients' opinions and comments and use their feedback to solve the workplace problems and

How victim sensitivity leads to uncooperative behavior via expectancies of injustice

Directory of Open Access Journals (Sweden)

Simona eMaltese

2016-01-01

Full Text Available According to the Sensitivity-to-mean-intentions (SeMI model, dispositional victim sensitivity involves a suspicious mindset that is activated by situational cues and guides subsequent information processing and behavior like a schema. Study 1 tested whether victim-sensitive persons are more prone to form expectancies of injustice in ambiguous situations and whether these expectancies mediate the relationship between victim sensitivity and cooperation behavior in a trust game. Results show an indirect effect of victim sensitivity on cooperation after unfair treatment (vs control condition, mediated by expectancies of injustice. In Study 2 we directly manipulated the tendency to form expectancies of injustice in ambiguous situations to test for causality. Results confirmed that the readiness to expect unjust outcomes led to lower cooperation, compared to a control condition. These findings provide direct evidence that expectancy tendencies are implicated in elevated victim sensitivity and are of theoretical and practical relevance.

Wind farms providing secondary frequency regulation: evaluating the performance of model-based receding horizon control

Directory of Open Access Journals (Sweden)

C. R. Shapiro

2018-01-01

Full Text Available This paper is an extended version of our paper presented at the 2016 TORQUE conference (Shapiro et al., 2016. We investigate the use of wind farms to provide secondary frequency regulation for a power grid using a model-based receding horizon control framework. In order to enable real-time implementation, the control actions are computed based on a time-varying one-dimensional wake model. This model describes wake advection and wake interactions, both of which play an important role in wind farm power production. In order to test the control strategy, it is implemented in a large-eddy simulation (LES model of an 84-turbine wind farm using the actuator disk turbine representation. Rotor-averaged velocity measurements at each turbine are used to provide feedback for error correction. The importance of including the dynamics of wake advection in the underlying wake model is tested by comparing the performance of this dynamic-model control approach to a comparable static-model control approach that relies on a modified Jensen model. We compare the performance of both control approaches using two types of regulation signals, RegA and RegD, which are used by PJM, an independent system operator in the eastern United States. The poor performance of the static-model control relative to the dynamic-model control demonstrates that modeling the dynamics of wake advection is key to providing the proposed type of model-based coordinated control of large wind farms. We further explore the performance of the dynamic-model control via composite performance scores used by PJM to qualify plants for regulation services or markets. Our results demonstrate that the dynamic-model-controlled wind farm consistently performs well, passing the qualification threshold for all fast-acting RegD signals. For the RegA signal, which changes over slower timescales, the dynamic-model control leads to average performance that surpasses the qualification threshold, but further

Tan, J K; Modrow, R E

1999-05-01

In this article, we discuss the traditional systems analysis perspective on end-user information requirements analysis and extend it to merge with the new accountability expectations perspective to guide the future planning and design of health organization information systems. Underlying the strategic relevance of health care information technology (HCIT) are three critical questions: (1) What is the ideal HCIT model for the health organization in terms of achieving strategic expertise and competitive advantage? Specifically, how does this model link industry performance standards with organizational performance and accountability expectations? (2) How should the limitations of past HCIT models be reconciled to the benefits presented by the superior arrangement of the ideal model in the context of changing accountability expectations? (3) How should alternative HCIT solutions be evaluated in light of evidence-based accountability and organizational performance benchmarking? Insights into these questions will ensure that health care managers, HCIT practitioners and researchers can continue to focus on the most critical issues in harnessing today's fast-paced changing technologies for evolving strategically relevant, performance-based health organization systems.

A sample of 263 subjects (average age 33.1 years [SD = 8.7], 56% men) consisting of cannabis users (n = 64), psychiatric inpatients (n = 175, most of whom were hospitalized for withdrawal), and a control group (n = 24) completed the questionnaire. Internal reliability was good (α= .87) and temporal reliability was satisfactory, with 24 of 48 items having a significant κ ≥ .41. Factor analysis showed four main factors that explained 42.1% of the total variance. The women feared Cognitive Impairment and Negative Effects, and Negative Behavioral Effects more than the men. The onset age of cannabis use, onset age of abuse, abuse and dependence were associated with fewer negative expectancies. Cannabis dependents differed from abusers by more Relaxation and Social Facilitation expectancies. Patients with major depressive episodes, panic disorder, social anxiety disorder, or posttraumatic stress disorder feared negative effects the most. Schizophrenic patients expected more Perceptual Enhancement and Craving. The French version of the Marijuana Effect Expectancy Questionnaire has good psychometric properties and is valid to assess cannabis expectancies in adolescents and adults with substance use disorders.

Full Text Available The primary condition for successful in second or foreign language learning is providing an adequate environment. It is as a medium of increasing the students’ language exposure in order to be able to success in acquiring second or foreign language profciency. This study was designed to propose the adequate English language input that can decrease the students’ anxiety in reading comprehension performance. Of the four skills, somehow reading can be regarded as especially important because reading is assumed to be the central means for learning new information. Some students, however, still encounter many problems in reading. It is because of their anxiety when they are reading. Providing and creating an interesting-contextual reading material and gratifed teachers can make out this problem which occurs mostly in Indonesian’s classrooms. It revealed that the younger learners of English there do not received adequate amount of the target language input in their learning of English. Hence, it suggested the adoption of extensive reading programs as the most effective means in the creation of an input-rich environment in EFL learning contexts. Besides they also give suggestion to book writers and publisher to provide myriad books that appropriate and readable for their students.

Life expectancy living with HIV: recent estimates and future implications.

2013-02-01

The life expectancy of people living with HIV has dramatically increased since effective antiretroviral therapy has been available, and still continues to improve. Here, we review the latest literature on estimates of life expectancy and consider the implications for future research. With timely diagnosis, access to a variety of current drugs and good lifelong adherence, people with recently acquired infections can expect to have a life expectancy which is nearly the same as that of HIV-negative individuals. Modelling studies suggest that life expectancy could improve further if there were increased uptake of HIV testing, better antiretroviral regimens and treatment strategies, and the adoption of healthier lifestyles by those living with HIV. In particular, earlier diagnosis is one of the most important factors associated with better life expectancy. A consequence of improved survival is the increasing number of people with HIV who are aged over 50 years old, and further research into the impact of ageing on HIV-positive people will therefore become crucial. The development of age-specific HIV treatment and management guidelines is now called for. Analyses on cohort studies and mathematical modelling studies have been used to estimate life expectancy of those with HIV, providing useful insights of importance to individuals and healthcare planning.

Full Text Available This study was conducted to identify various future expectations of high school students in southeastern Turkey and factors behind their expectations. The sample of the study, which had a descriptive and associational survey design consisted of 1106 students randomly selected from 54 different high schools located in nine cities in southeastern Turkey. Data were collected through the “Future Expectation Scale (FES” developed by the researcher. Results indicated that personal and professional future, educational future, economic future and social future expectations of high school students in southeastern Turkey were generally above the average level. According to the study, being a teacher and a doctor took the first place among several professions to be further preferred by high school students. It was also concluded that future expectations of high school students did not differ on gender, high school type, CGPA, level of mother education, father’s occupation, family income level, the number of siblings, receiving pre-school education, and language spoken at home. On the other hand, future expectations of high school students were found to differ on the city where students being taught, grade level, corporal punishment, and tendency toward being a dropout.

Full Text Available Background: Mothers develop expectations regarding midwives’ care during labour and when these are not met mothers become dissatisfied and eventually have negative experiences of their labour. It is only when mothers’ voices are heard by midwives in the labour ward that efficient and quality care will be provided. To ensure mothers have a positive experience of labour, midwives should include mothers’ expectations when caring for them.Objective: The purpose of the study on which this article is based was to determine mothers’ expectations of midwives’ care during labour. To achieve this purpose the researcher sought to explore and describe mothers’ expectations of midwives’ care during labour in a specific public hospital in Gauteng.Method: A qualitative, exploratory, descriptive and contextual study design was used. Face-to-face, in-depth individual interviews were conducted with mothers about their expectations of midwives’ care during labour. Data were then analysed with an open descriptive method of coding (Tesch’s eight steps that is appropriate for qualitative research to identify categories. The data was also analysed by an independent coder. The categories were subsequently placed within a holistic health promotive nursing theory that encompasses body, mind and spirit.Results: The findings revealed the provision of comfort and support as the two main aspects that the mothers expected from the midwives’ care. The mothers expected midwives to improve their communication skills with them (mothers as well as with fathers or partners if they were available. The mothers expected midwives to facilitate bonding between mother, father and baby, and also encouraged the midwives to improve their (midwives’ knowledge, skills and morale. Conclusion: The results of this study should assist midwives in providing holistic quality care to mothers during labour, thus providing satisfaction and positive experiences of the mothers�

The Accreditation Council for Graduate Medical Education requires semiannual Milestone reporting on all residents. Milestone expectations of performance are unknown. Determine pediatric program director (PD) minimum Milestone expectations for residents prior to being ready to supervise and prior to being ready to graduate. Mixed methods survey of pediatric PDs on their programs' Milestone expectations before residents are ready to supervise and before they are ready to graduate, and in what ways PDs use Milestones to make supervision and graduation decisions. If programs had no established Milestone expectations, PDs indicated expectations they considered for use in their program. Mean minimum Milestone level expectations adjusted for program size, region, and clustering of Milestone expectations by program were calculated for prior to supervise and prior to graduate. Free-text questions were analyzed using thematic analysis. The response rate was 56.8% (113/199). Most programs had no required minimum Milestone level before residents are ready to supervise (80%; 76/95) or ready to graduate (84%; 80/95). For readiness to supervise, minimum Milestone expectations PDs considered establishing for their program were highest for humanism (2.46, 95% CI: 2.21-2.71) and professionalization (2.37, 2.15-2.60). Minimum Milestone expectations for graduates were highest for help-seeking (3.14, 2.83-3.46). Main themes included the use of Milestones in combination with other information to assess learner performance and Milestones are not equally weighted when making advancement decisions. Most PDs have not established program minimum Milestones, but would vary such expectations by competency. Copyright © 2018. Published by Elsevier Inc.

Medical resident education in the United States has been a matter of national priority for decades, exemplified initially through the Liaison Committee for Graduate Medical Education and then superseded by the Accreditation Council for Graduate Medical Education. A recent Special Report in the New England Journal of Medicine, however, has described resident educational programs to date as prescriptive, noting an absence of innovation in education. Current aims of contemporary medical resident education are thus being directed at ensuring quality in learning as well as in patient care. Achievement and work-motivation theories attempt to explain people's choice, performance, and persistence in tasks. Expectancy Theory as one such theory was reviewed in detail, appearing particularly applicable to surgical residency training. Correlations between Expectancy Theory as a work-motivation theory and residency education were explored. Understanding achievement and work-motivation theories affords an opportunity to gain insight into resident motivation in training. The application of Expectancy Theory in particular provides an innovative perspective into residency education. Afforded are opportunities to promote the development of programmatic methods facilitating surgical resident motivation in education.

Many athletes experience a discrepancy between the roles they expect to fulfill and the roles they eventually occupy. Drawing from met expectations theory, we applied response surface methodology to examine how role expectations, in relation to role experiences, influence perceptions of group cohesion among Canadian Interuniversity Sport athletes (N = 153). On the basis of data from two time points, as athletes approached and exceeded their role contribution expectations, they reported higher perceptions of task cohesion. Furthermore, as athletes approached and exceeded their social involvement expectations, they reported higher perceptions of social cohesion. These response surface patterns-pertaining to task and social cohesion-were driven by the positive influence of role experiences. On the basis of the interplay between athletes' role experiences and their perception of the group environment, efforts to improve team dynamics may benefit from focusing on improving the quality of role experiences, in conjunction with developing realistic role expectations.

Expected usability is not a valid indicator of experienced usability

Full Text Available Usability is a core construct of website evaluation and inherently defined as interactive. Yet, when analysing first impressions of websites, expected usability, i.e., before use, is of interest. Here we investigate to what extend ratings of expected usability are related to (a experienced usability, i.e., ratings after use, and (b objective usability measures, i.e., task performance. Furthermore, we try to elucidate how ratings of expected usability are correlated to aesthetic judgments. In an experiment, 57 participants submitted expected usability ratings after the presentation of website screenshots in three viewing-time conditions (50, 500, and 10,000 ms and after an interactive task (experienced usability. Additionally, objective usability measures (task completion and duration and subjective aesthetics evaluations were recorded for each website. The results at both the group and individual level show that expected usability ratings are not significantly related either to experienced usability or objective usability measures. Instead, they are highly correlated with aesthetics ratings. Taken together, our results highlight the need for interaction in empirical website usability testing, even when exploring very early usability impressions. In our study, user ratings of expected usability were no valid proxy neither for objective usability nor for experienced website usability.

to provide a narrative overview of the values schema underpinning women׳s expectations of public maternity-care services using an episodes-of-care framework. focus-group discussions and in-depth interviews were undertaken with Western Australian women who had opted for public maternity care to determine the values schema apparent in their expectations of their care. public maternity-care services in metropolitan (i.e. Armadale, Osborne Park and Rockingham) and regional (i.e. Broome, Geraldton, Bunbury) Western Australia. women interviewed were found to have consistent values schema underpinning their maternity-care expectations and evaluations. the current study suggests that while women׳s choices and experiences of maternity care may differ on a range of dimensions, the values schema underlying their care expectations and subsequent evaluations are similar. The study findings resonate with past Australian research regarding women׳s expectations of public maternity care, but complement it by providing a coherent narrative of core underpinning stage-specific values schema. These may assist maternity-care policy makers, practitioners and researchers seeking to better understand and comprehensively respond to women׳s maternity-care expectations.

The expectations of patient are one of the determining factors of healthcare service. The purpose of this study is to measure the Patients' Expectations, based on Patient's Rights. This study was done with Likert-Survey in Trabzon population. The analyses showed that the level of the expectations of the patient was high on the factor of receiving information and at an acceptable level on the other factors. Statistical meaningfulness was determined between age, sex, education, health insurance, and the income of the family and the expectations of the patients (pstudy, the current legal regulations have higher standards than the expectations of the patients. The reason that the satisfaction of the patients high level is interpreted due to the fact that the level of the expectation is low. It is suggested that the educational and public awareness studies on the patients' rights must be done in order to increase the expectations of the patients.

2013-01-01

Patient-centred healthcare is becoming a more significant success factor in the design of integrated healthcare systems. The objective of this study is to structure a patient-relevant hierarchy of needs and expectations for the design of organised healthcare delivery systems. A questionnaire with 84 items was conducted with N = 254 healthcare experts and N = 670 patients. Factor analyses were performed using SPSS©18. The number of factors retained was controlled by Kaiser's criterion, validation of screeplots and interpretability of the items. Cronbach's α was used to assess the internal consistency of the subscales. Exploratory factor analysis led to 24 factors in the expert sample and 20 in the patient sample. After analysing the screeplots, confirmatory factor analyses were computed for 7-factor solutions accounting for 42.963% of the total variance and Kaiser-Meyer-Olkin of 0.914 for the patients (experts: 38.427%, Kaiser-Meyer-Olkin = 0.797). Cronbach's α ranged between 0.899 and 0.756. Based on the analysis, coordinated care could be differentiated into seven dimensions: access, data and information, service and infrastructure, professional care, interpersonal care, individualised care, continuity and coordination. The study provides insight into patient and experts expectations towards the organisation of integrated healthcare delivery systems. If providers and payers can take into account patient needs and expectations while implementing innovative healthcare delivery systems, greater acceptance and satisfaction will be achieved. In the best case, this will lead to better adherence resulting in better clinical outcomes.

Sex and life expectancy.

2012-12-01

A sexual dimorphism in human life expectancy has existed in almost every country for as long as records have been kept. Although human life expectancy has increased each year, females still live longer, on average, than males. Undoubtedly, the reasons for the sex gap in life expectancy are multifaceted, and it has been discussed from both sociological and biological perspectives. However, even if biological factors make up only a small percentage of the determinants of the sex difference in this phenomenon, parity in average life expectancy should not be anticipated. The aim of this review is to highlight biological mechanisms that may underlie the sexual dimorphism in life expectancy. Using PubMed, ISI Web of Knowledge, and Google Scholar, as well as cited and citing reference histories of articles through August 2012, English-language articles were identified, read, and synthesized into categories that could account for biological sex differences in human life expectancy. The examination of biological mechanisms accounting for the female-based advantage in human life expectancy has been an active area of inquiry; however, it is still difficult to prove the relative importance of any 1 factor. Nonetheless, biological differences between the sexes do exist and include differences in genetic and physiological factors such as progressive skewing of X chromosome inactivation, telomere attrition, mitochondrial inheritance, hormonal and cellular responses to stress, immune function, and metabolic substrate handling among others. These factors may account for at least a part of the female advantage in human life expectancy. Despite noted gaps in sex equality, higher body fat percentages and lower physical activity levels globally at all ages, a sex-based gap in life expectancy exists in nearly every country for which data exist. There are several biological mechanisms that may contribute to explaining why females live longer than men on average, but the complexity of the

The Temporal Derivative of Expected Utility: A Neural Mechanism for Dynamic Decision-making

Science.gov (United States)

Zhang, Xian; Hirsch, Joy

2012-01-01

Real world tasks involving moving targets, such as driving a vehicle, are performed based on continuous decisions thought to depend upon the temporal derivative of the expected utility (∂V/∂t), where the expected utility (V) is the effective value of a future reward. However, those neural mechanisms that underlie dynamic decision-making are not well understood. This study investigates human neural correlates of both V and ∂V/∂t using fMRI and a novel experimental paradigm based on a pursuit-evasion game optimized to isolate components of dynamic decision processes. Our behavioral data show that players of the pursuit-evasion game adopt an exponential discounting function, supporting the expected utility theory. The continuous functions of V and ∂V/∂t were derived from the behavioral data and applied as regressors in fMRI analysis, enabling temporal resolution that exceeded the sampling rate of image acquisition, hyper-temporal resolution, by taking advantage of numerous trials that provide rich and independent manipulation of those variables. V and ∂V/∂t were each associated with distinct neural activity. Specifically, ∂V/∂t was associated with anterior and posterior cingulate cortices, superior parietal lobule, and ventral pallidum, whereas V was primarily associated with supplementary motor, pre and post central gyri, cerebellum, and thalamus. The association between the ∂V/∂t and brain regions previously related to decision-making is consistent with the primary role of the temporal derivative of expected utility in dynamic decision-making.

The degree to which consumers expect foods to satisfy hunger, referred to as expected satiation, has been reported to predict food intake. Yet this relationship has not been established precisely, at a quantitative level. We sought to explore this relationship in detail by determining whether expected satiation predicts the actual intake of semi-solid desserts. Two separate experiments were performed: the first used variations of a given food (eight apple purées), while the second involved a panel of different foods within a given category (eight desserts). Both experiments studied the consumption of two products assigned to volunteers based on their individual liking and expected satiation ratings, given ad libitum at the end of a standardised meal. A linear model was used to find predictors of food intake and included expected satiation scores, palatability scores, BMI, age, sex, TFEQ-R, TFEQ-D, water consumption during the meal, reported frequency of eating desserts, and reported frequency of consuming tested products as explanatory variables. Expected satiation was a significant predictor of actual food intake in both experiments (apple purée: F(1,97) = 18.60, P desserts: F(1,106) = 9.05, P desserts, on group and on individual level. Our results confirm the importance of expected satiation as a predictor of subsequent food intake, but highlight the need to study individual consumption behaviour and preferences in order to fully understand the role of expected satiation.

Anomalous vacuum expectation values

International Nuclear Information System (INIS)

Suzuki, H.

1986-01-01

The anomalous vacuum expectation value is defined as the expectation value of a quantity that vanishes by means of the field equations. Although this value is expected to vanish in quantum systems, regularization in general produces a finite value of this quantity. Calculation of this anomalous vacuum expectation value can be carried out in the general framework of field theory. The result is derived by subtraction of divergences and by zeta-function regularization. Various anomalies are included in these anomalous vacuum expectation values. This method is useful for deriving not only the conformal, chiral, and gravitational anomalies but also the supercurrent anomaly. The supercurrent anomaly is obtained in the case of N = 1 supersymmetric Yang-Mills theory in four, six, and ten dimensions. The original form of the energy-momentum tensor and the supercurrent have anomalies in their conservation laws. But the modification of these quantities to be equivalent to the original one on-shell causes no anomaly in their conservation laws and gives rise to anomalous traces

There is a poor association between the dentist's evaluation of denture quality and patients' satisfaction with their dentures. Possible differences between dental professionals and patients' expectations might help explain differences in outcome evaluations. This study compared scores given by a dentist, a dental technician and patients for their expectations before and their final evaluation after complete dentures treatment. Twenty completely edentulous patients, a prosthodontist and a dental technician provided scores for the expected aesthetic and functional results of their dentures based on a visual analogue scale at baseline. Post-treatment completion ratings were given after adjustments, by dentist and patients. The dental technician provided post-treatment completion ratings after completing the dentures. The patients had higher expectations than the dental technician and the dentist perceived for both aesthetic and function (P < 0.001). The patients also presented higher post-treatment completion ratings than the dental professionals perceived for final aesthetics (P = 0.016, Kendall's W = 0.207) and function (P = 0.002, Kendall's W = 0.303). Only the dentist presented a statistically significant difference between expectations (lower) and final (higher) outcomes for aesthetics (P = 0.017) and function (P = 0.003). There was no correlation between expectations and post-treatment completion ratings according to the patients' age. There was also no correlation between the patients' gender and expectation scores. Patients presented higher expectations regarding their dentures than dental professionals. The dentist believed that dentures would bring fewer benefits than patients did, but his perception of denture benefits post-treatment was significantly higher than his expectations.

Can expectations produce symptoms from infrasound associated with wind turbines?

Crichton, Fiona; Dodd, George; Schmid, Gian; Gamble, Greg; Petrie, Keith J

2014-04-01

The development of new wind farms in many parts of the world has been thwarted by public concern that subaudible sound (infrasound) generated by wind turbines causes adverse health effects. Although the scientific evidence does not support a direct pathophysiological link between infrasound and health complaints, there is a body of lay information suggesting a link between infrasound exposure and health effects. This study tested the potential for such information to create symptom expectations, thereby providing a possible pathway for symptom reporting. A sham-controlled double-blind provocation study, in which participants were exposed to 10 min of infrasound and 10 min of sham infrasound, was conducted. Fifty-four participants were randomized to high- or low-expectancy groups and presented audiovisual information, integrating material from the Internet, designed to invoke either high or low expectations that exposure to infrasound causes specified symptoms. High-expectancy participants reported significant increases, from preexposure assessment, in the number and intensity of symptoms experienced during exposure to both infrasound and sham infrasound. There were no symptomatic changes in the low-expectancy group. Healthy volunteers, when given information about the expected physiological effect of infrasound, reported symptoms that aligned with that information, during exposure to both infrasound and sham infrasound. Symptom expectations were created by viewing information readily available on the Internet, indicating the potential for symptom expectations to be created outside of the laboratory, in real world settings. Results suggest psychological expectations could explain the link between wind turbine exposure and health complaints.

Patients' expectations of osteopathic care have been little researched. The aim of this study was to quantify the most important expectations of patients in private UK osteopathic practices, and the extent to which those expectations were met or unmet. The study involved development and application of a questionnaire about patients' expectations of osteopathic care. The questionnaire drew on an extensive review of the literature and the findings of a prior qualitative study involving focus groups exploring the expectations of osteopathic patients. A questionnaire survey of osteopathic patients in the UK was then conducted. Patients were recruited from a random sample of 800 registered osteopaths in private practice across the UK. Patients were asked to complete the questionnaire which asked about 51 aspects of expectation, and post it to the researchers for analysis.The main outcome measures were the patients-perceived level of expectation as assessed by the percentage of positive responses for each aspect of expectation, and unmet expectation as computed from the proportion responding that their expectation "did not happen". 1649 sets of patient data were included in the analysis. Thirty five (69%) of the 51 aspects of expectation were prevalent, with listening, respect and information-giving ranking highest. Only 11 expectations were unmet, the most often unmet were to be made aware that there was a complaints procedure, to find it difficult to pay for osteopathic treatment, and perceiving a lack of communication between the osteopath and their GP. The findings reflected the complexity of providing osteopathic care and meeting patients' expectations. The results provided a generally positive message about private osteopathic practice. The study identified certain gaps between expectations and delivery of care, which can be used to improve the quality of care. The questionnaire is a resource for future research.

Results 1649 sets of patient data were included in the analysis. Thirty five (69%) of the 51 aspects of expectation were prevalent, with listening, respect and information-giving ranking highest. Only 11 expectations were unmet, the most often unmet were to be made aware that there was a complaints procedure, to find it difficult to pay for osteopathic treatment, and perceiving a lack of communication between the osteopath and their GP. Conclusions The findings reflected the complexity of providing osteopathic care and meeting patients’ expectations. The results provided a generally positive message about private osteopathic practice. The study identified certain gaps between expectations and delivery of care, which can be used to improve the quality of care. The questionnaire is a resource for future research

The attentional white bear phenomenon: the mandatory allocation of attention to expected distractor locations.

Tsal, Yehoshua; Makovski, Tal

2006-04-01

The authors devised a prestimulus-probe method to assess the allocation of attention as a function of participants' top-down expectancies concerning distractor and target locations. Participants performed the flanker task, and distractor locations remained fixed. On some trials, instead of the flanker display, either 2 simultaneous dots or a horizontal line appeared. The dot in the expected distractor location was perceived to occur before the dot in the expected empty location, and the line appeared to extend from the expected distractor location to the expected empty location, suggesting that attention is allocated to expected distractor locations prior to stimulus onset. The authors propose that a process-all mechanism guides attention to expected locations of all stimuli regardless of task demands and that this constitutes a major cause for failures of selective attention.

Factors such as an external focus of attention (EF) and augmented feedback (AF) have been shown to improve performance. However, the efficacy of providing AF to enhance motor performance has never been compared with the effects of an EF or an internal focus of attention (IF). Therefore, the aim of the present study was to identify which of the three conditions (AF, EF or IF) leads to the highest performance in a countermovement jump (CMJ). Nineteen volunteers performed 12 series of 8 maximum CMJs. Changes in jump height between conditions and within the series were analysed. Jump heights differed between conditions (P jump heights at the end of the series in AF (+1.60%) and lower jump heights at the end of the series in EF (-1.79%) and IF (-1.68%) were observed. Muscle activity did not differ between conditions. The differences between conditions and within the series provide evidence that AF leads to higher performance and better progression within one series than EF and IF. Consequently, AF seems to outperform EF and IF when maximising jump height.

Full Text Available Backgrounds and Objectives: Assessing the educational services provided for students and determining the gap between the current status and the expected status can pave the way for developing programs to promote the quality of educational services. This study was performed aiming at determining the quality of educational services in Shahroud University of Medical Sciences in 2010.Methods: In this cross-sectional study, 274 students of Shahroud University of Medical Sciences were selected by random sampling method. The data were collected using SERVQUAL standard questionnaire. The 27-question questionnaire included two sections of demographic data and five-dimension educational services quality, which was completed as self-administered. The data were analyzed through independent samples t-test, paired samples t-test, and one-way ANOVA.Results: There were quality gaps in all dimensions of educational services quality and the statements to assess them. The biggest quality gap was in the responsiveness dimension (-1.45, and the lowest gap was in the reliability dimension (-1.14. The mean gap scores in female students were higher than male students in all five dimensions of educational services quality, and this difference were statistically significant (p<0.001.Conclusion: The results of this study showed that the students’ expectations are not fulfilled in all service dimensions. Therefore, responsiveness, customer-orientation, improvement of work processes and physical spaces, and paying attention to other dimensions could play a key role in promoting the quality of educational services.

Response Expectancy and the Placebo Effect.

Science.gov (United States)

Kirsch, Irving

2018-01-01

In this chapter, I review basic tenets of response expectancy theory (Kirsch, 1985), beginning with the important distinction between response expectancies and stimulus expectancies. Although both can affect experience, the effects of response expectancies are stronger and more resistant to extinction than those of stimulus expectancies. Further, response expectancies are especially important to understanding placebo effects. The response expectancy framework is consistent with and has been amplified by the Bayesian model of predictive coding. Clinical implications of these phenomena are exemplified. © 2018 Elsevier Inc.

Motor unit recruitment by size does not provide functional advantages for motor performance.

Dideriksen, Jakob L; Farina, Dario

2013-12-15

It is commonly assumed that the orderly recruitment of motor units by size provides a functional advantage for the performance of movements compared with a random recruitment order. On the other hand, the excitability of a motor neuron depends on its size and this is intrinsically linked to its innervation number. A range of innervation numbers among motor neurons corresponds to a range of sizes and thus to a range of excitabilities ordered by size. Therefore, if the excitation drive is similar among motor neurons, the recruitment by size is inevitably due to the intrinsic properties of motor neurons and may not have arisen to meet functional demands. In this view, we tested the assumption that orderly recruitment is necessarily beneficial by determining if this type of recruitment produces optimal motor output. Using evolutionary algorithms and without any a priori assumptions, the parameters of neuromuscular models were optimized with respect to several criteria for motor performance. Interestingly, the optimized model parameters matched well known neuromuscular properties, but none of the optimization criteria determined a consistent recruitment order by size unless this was imposed by an association between motor neuron size and excitability. Further, when the association between size and excitability was imposed, the resultant model of recruitment did not improve the motor performance with respect to the absence of orderly recruitment. A consistent observation was that optimal solutions for a variety of criteria of motor performance always required a broad range of innervation numbers in the population of motor neurons, skewed towards the small values. These results indicate that orderly recruitment of motor units in itself does not provide substantial functional advantages for motor control. Rather, the reason for its near-universal presence in human movements is that motor functions are optimized by a broad range of innervation numbers.

Background Despite safe and cost-effective venous thromboembolism (VTE) prevention measures, VTE prophylaxis rates are often suboptimal. Healthcare reform efforts emphasize transparency through programs to report performance, and payment incentives through programs to pay-for-performance. Objective To sequentially examine an individualized physician dashboard and pay-for-performance program to improve VTE prophylaxis rates amongst hospitalists. Design Retrospective analysis of 3144 inpatient admissions. After a baseline observation period, VTE prophylaxis compliance was compared during both interventions. Setting 1060-bed tertiary care medical center. Participants 38 part- and full-time academic hospitalists. Interventions A Web-based hospitalist dashboard provided VTE prophylaxis feedback. After 6 months of feedback only, a pay-for-performance program was incorporated, with graduated payouts for compliance rates of 80-100%. Measurements Prescription of American College of Chest Physicians guideline-compliant VTE prophylaxis and subsequent pay-for-performance payments. Results Monthly VTE prophylaxis compliance rates were 86% (95% CI: 85, 88), 90% (95% CI: 88, 93), and 94% (95% CI: 93, 96) during the baseline, dashboard, and combined dashboard/pay-for-performance periods, respectively. Compliance significantly improved with the use of the dashboard (p=0.01) and addition of the pay-for-performance program (p=0.01). The highest rate of improvement occurred with the dashboard (1.58%/month; p=0.01). Annual individual physician performance payments ranged from $53 to $1244 (mean $633; SD ±350). Conclusions Direct feedback using dashboards was associated with significantly improved compliance, with further improvement after incorporating an individual physician pay-for-performance program. Real-time dashboards and physician-level incentives may assist hospitals in achieving higher safety and quality benchmarks. PMID:25545690

Loss of life expectancy derived from a standardized mortality ratio in Denmark, Finland, Norway and Sweden.

Skriver, Mette Vinther; Væth, Michael; Støvring, Henrik

2018-01-01

The standardized mortality ratio (SMR) is a widely used measure. A recent methodological study provided an accurate approximate relationship between an SMR and difference in lifetime expectancies. This study examines the usefulness of the theoretical relationship, when comparing historic mortality data in four Scandinavian populations. For Denmark, Finland, Norway and Sweden, data on mortality every fifth year in the period 1950 to 2010 were obtained. Using 1980 as the reference year, SMRs and difference in life expectancy were calculated. The assumptions behind the theoretical relationship were examined graphically. The theoretical relationship predicts a linear association with a slope, [Formula: see text], between log(SMR) and difference in life expectancies, and the theoretical prediction and calculated differences in lifetime expectancies were compared. We examined the linear association both for life expectancy at birth and at age 30. All analyses were done for females, males and the total population. The approximate relationship provided accurate predictions of actual differences in lifetime expectancies. The accuracy of the predictions was better when age was restricted to above 30, and improved if the changes in mortality rate were close to a proportional change. Slopes of the linear relationship were generally around 9 for females and 10 for males. The theoretically derived relationship between SMR and difference in life expectancies provides an accurate prediction for comparing populations with approximately proportional differences in mortality, and was relatively robust. The relationship may provide a useful prediction of differences in lifetime expectancies, which can be more readily communicated and understood.

Expected Accuracy when using Non-Calibrated CernoxTM Sensors

Within the ITER-CERN collaboration agreement, task “PROCUREMENT OF CRYOGENIC THERMOMETERS TO MONITOR ITER MAGNETS AND FEEDER TEMPERATURES”, CERN is investigating what would be the expected accuracy when using non-calibrated Cernox™ temperature sensors at 4.2 K. The cernox™ is a resistive type temperature sensor that is capable of measuring the full temperature range of interest for ITER, it is 4.2 K to 300 K. Non-calibrated cernox™ sensors are delivered with a table listing the resistance at the following temperatures: 4.2 K, 77 K and 300 K. CERN has deployed several thousands of individually calibrated cernox™ sensors and they are used to compare the manufacturer data at 4.2 K with their individual calibration performed by CERN. Within a sample size of 5’941 sensors, 99.39% of the population is able to provide a measurement within +/-0.1 K at 4.2 well within the requirements at low temperature specified by ITER.

Comparisons between expectations and outcomes are critical for learning. Termed prediction errors, the violations of expectancy that occur when outcomes differ from expectations are used to modify value and shape behaviour. In the present study, we examined how a wide range of expectancy violations impacted neural signals associated with feedback processing. Participants performed a time estimation task in which they had to guess the duration of one second while their electroencephalogram was recorded. In a key manipulation, we varied task difficulty across the experiment to create a range of different feedback expectancies - reward feedback was either very expected, expected, 50/50, unexpected, or very unexpected. As predicted, the amplitude of the reward positivity, a component of the human event-related brain potential associated with feedback processing, scaled inversely with expectancy (e.g., unexpected feedback yielded a larger reward positivity than expected feedback). Interestingly, the scaling of the reward positivity to outcome expectancy was not linear as would be predicted by some theoretical models. Specifically, we found that the amplitude of the reward positivity was about equivalent for very expected and expected feedback, and for very unexpected and unexpected feedback. As such, our results demonstrate a sigmoidal relationship between reward expectancy and the amplitude of the reward positivity, with interesting implications for theories of reinforcement learning.

Cognitive associations with alcohol predict both current and future use in youth and young adults. Much cognitive and social cognitive research suggests that exposure to information may have unconscious influences on thinking and behavior. The present study assessed the impact of information statements on the accessibility of alcohol outcome expectancies. The 2 studies reported here investigated the effects of exposure to alcohol statements typical of informational approaches to prevention on the accessibility of alcohol outcome expectancies. High school and university students were presented with information statements about the effects of alcohol and other commercial products. The alcohol statements were taken from expectancy questionnaires. Some of these statements were presented as facts and others as myths. The retention of detailed information about these statements was manipulated by (i) divided attention versus focused attention or (ii) immediate versus delayed testing. Accessibility of personal alcohol outcome expectancies was subsequently measured using an open-ended question about the expected effects of alcohol. Participants reported more alcohol outcomes seen during the information task as personal expectations about the effects of alcohol use than similar unseen items. Paradoxically, myth statements were also more likely to be reported as expectancies than unseen items in all conditions. Additionally, myth statements were generated less often than fact statements only under the condition of immediate testing with strong content processing instructions. These observations are consistent with findings from cognitive research where familiarity in the absence of explicit memory can have an unconscious influence on performance. In particular, the exposure to these items in an informational format increases accessibility of the seen items even when the participants were told that they were myths. The findings have implications for the development of

Techniques for analyzing the level of performance of nuclear materials accounting systems in terms of the four performance measures, total amount of loss, loss-detection time, loss-detection probability, and false-alarm probability, are presented. These techniques are especially useful for analyzing the expected performance of near-real-time (dynamic) accounting systems. A conservative estimate of system performance is provided by the CUSUM (cumulative summation of materials balances) test. Graphical displays, called performance surfaces, are developed as convenient tools for representing systems performance, and examples from a recent safeguards study of a nuclear fuels reprocessing plant are given. 6 refs

There is concern about graduating thoracic trainees' independent operative skills due to limited autonomy in training. This study compared faculty and trainee expected levels of autonomy with intraoperative measurements of autonomy for common cardiothoracic operations. Participants underwent frame-of-reference training on the 4-point Zwisch scale of operative autonomy (show and tell → active help → passive help → supervision only) and evaluated autonomy in actual cases using the Zwisch Me!! mobile application. A separate "expected autonomy" survey elicited faculty and resident perceptions of how much autonomy a resident should have for six common operations: decortication, wedge resection, thoracoscopic lobectomy, coronary artery bypass grafting, aortic valve replacement, and mitral valve repair. Thirty-three trainees from 7 institutions submitted evaluations of 596 cases over 18 months (March 2015 to September 2016). Thirty attendings subsequently provided their evaluation of 476 of those cases (79.9% response rate). Expected autonomy surveys were completed by 21 attendings and 19 trainees from 5 institutions. The six operations included in the survey constituted 47% (226 of 476) of the cases evaluated. Trainee and attending expectations did not differ significantly for senior trainees. Both groups expected significantly higher levels of autonomy than observed in the operating room for all six types of cases. Although faculty and trainees both expect similar levels of autonomy in the operating room, real-time measurements of autonomy show a gap between expectations and reality. Decreasing this gap will require a concerted effort by both faculty and residents to focus on the development of independent operative skills. Copyright © 2017 The Society of Thoracic Surgeons.

This study is a qualitative analysis examining caregivers' expectations for pediatricians with regard to behavioral health care. Fifty-five parents/caregivers of children seen in an urban primary care clinic participated in semistructured interviews. Participants were parents or guardians of children between the ages of 2 and 17 years, referred from the pediatric clinic to the mental health center. Interviews were analyzed using grounded theory methods. Pertinent themes were the following: expected range of care, components of an effective primary care provider (PCP) relationship, action of the PCP, and parent reaction to PCP intervention. Forty-seven percent of caregivers saw the PCP role as strictly for physical health care; 53% expected the PCP to have a role in both physical and behavioral health. Responses were overwhelmingly positive from caregivers when the PCP asked about or conducted a behavioral health intervention. Caregivers did not consistently expect but responded positively to PCPs engaging around behavioral health concerns. © The Author(s) 2015.

Current detectors for Very-High-Energy γ-ray astrophysics are either pointing instruments with a small field of view (Cherenkov telescopes), or large field-of-view instruments with relatively large energy thresholds (extensive air shower detectors). In this article, we propose a new hybrid extensive air shower detector sensitive in an energy region starting from about 100 GeV. The detector combines a small water-Cherenkov detector, able to provide a calorimetric measurement of shower particles at ground, with resistive plate chambers which contribute significantly to the accurate shower geometry reconstruction. A full simulation of this detector concept shows that it is able to reach better sensitivity than any previous gamma-ray wide field-of-view experiment in the sub-TeV energy region. It is expected to detect with a 5σ significance a source fainter than the Crab Nebula in one year at 100 GeV and, above 1 TeV a source as faint as 10% of it. As such, this instrument is suited to detect transient phenomena making it a very powerful tool to trigger observations of variable sources and to detect transients coupled to gravitational waves and gamma-ray bursts.

Accurate Evaluation of Expected Shortfall for Linear Portfolios with Elliptically Distributed Risk Factors

Dobrislav Dobrev∗

Full Text Available We provide an accurate closed-form expression for the expected shortfall of linear portfolios with elliptically distributed risk factors. Our results aim to correct inaccuracies that originate in Kamdem (2005 and are present also in at least thirty other papers referencing it, including the recent survey by Nadarajah et al. (2014 on estimation methods for expected shortfall. In particular, we show that the correction we provide in the popular multivariate Student t setting eliminates understatement of expected shortfall by a factor varying from at least four to more than 100 across different tail quantiles and degrees of freedom. As such, the resulting economic impact in financial risk management applications could be significant. We further correct such errors encountered also in closely related results in Kamdem (2007 and 2009 for mixtures of elliptical distributions. More generally, our findings point to the extra scrutiny required when deploying new methods for expected shortfall estimation in practice.

Bayesian projection of life expectancy accounting for the HIV/AIDS epidemic

Directory of Open Access Journals (Sweden)

Jessica Godwin

2017-11-01

Full Text Available Background: While probabilistic projection methods for projecting life expectancy exist, few account for covariates related to life expectancy. Generalized HIV/AIDS epidemics have a large, immediate negative impact on the life expectancy in a country, but this impact can be mitigated by widespread use of antiretroviral therapy (ART. Thus, projection methods for countries with generalized HIV/AIDS epidemics could be improved by accounting for HIV prevalence, the future course of the epidemic, and ART coverage. Methods: We extend the current Bayesian probabilistic life expectancy projection methods of Raftery et al. (2013 to account for HIV prevalence and adult ART coverage in countries with generalized HIV/AIDS epidemics. Results: We evaluate our method using out-of-sample validation. We find that the proposed method performs better than the method that does not account for HIV prevalence or ART coverage for projections of life expectancy in countries with a generalized epidemic, while projections for countries without an epidemic remain essentially unchanged. Conclusions: In general, our projections show rapid recovery to pre-epidemic life expectancy levels in the presence of widespread ART coverage. After the initial life expectancy recovery, we project a steady rise in life expectancy until the end of the century. Contribution: We develop a simple Bayesian hierarchical model for long-term projections of life expectancy while accounting for HIV/AIDS prevalence and coverage of ART. The method produces well-calibrated projections for countries with generalized HIV/AIDS epidemics up to 2100 while having limited data demands.

2011-12-01

Full Text Available Theme – It is know that the large public and auditors hold different beliefs about the auditors’ duties and responsibilities. In this conditions audit expectation gap represents that level of expectation that remains uncovered. In this study paper, audit expectation gap represents the difference between the achievements of public auditors and the expectations that general public (students have beyond those responsibility. Purpose – The evolution of audit expectation gap has been examined in various countries, but the extent of the concept has not been investigated so much in public area. This study attempts to assess the perceptions of possible future auditors, students, regarding the existence of expectation gap in public area. Literature review – A review of the literature identifies many researches who define the concept since was given the first definition of audit expectation gap as the difference between the levels of expected performance and the results that auditors give, but just a few analysis the public area using students’ knowledge to understand the perception of future users of accounting information or potential bidders of accounting information. Methodology – This paper represents the beginning of a broader study that will be part of the doctoral thesis entitled “Organization and exercise of public audit in Romania”, started in 2009 at University Babes Bolyai from Cluj Napoca, coordinated by PhD Professor Matis Dumitru. The aim of this paper is to explore the findings of an empirical study, made on 352 students, were the primary data used were obtained through a questionnaire technique regarding the audit expectation gap in the public sector in Romania, looking into future to obtain responses using a larger respondent group. Findings – A reasonableness gap was uncovered, there is a gap between the expectation of students regarding the public auditors' profession and their results and there are differences

Preoperative expectations of outcome of total hip and knee arthroplasty are important determinants of patients' satisfaction and functional outcome. Aims of the study were (1) to translate the Hospital for Special Surgery Hip Replacement Expectations Survey and Knee Replacement Expectations Survey into Dutch and (2) to study test-retest reliability and concurrent validity. Patients scheduled for total hip (N = 112) or knee replacement (N = 101) were sent the Dutch Expectations Surveys twice with a 2 week interval to determine test-retest reliability. To determine concurrent validity, the Expectation WOMAC was sent. The results for the Dutch Hip Replacement Expectations Survey revealed good test-retest reliability (ICC 0.87), no bias and good internal consistency (alpha 0.86) (N = 72). The correlation between the Hip Expectations Score and the Expectation WOMAC score was 0.59 (N = 86). The results for the Dutch Knee Replacement Expectations Survey revealed good test-retest reliability (ICC 0.79), no bias and good internal consistency (alpha 0.91) (N = 46). The correlation with the Expectation WOMAC score was 0.52 (N = 57). Both Dutch Expectations Surveys are reliable instruments to determine patients' expectations before total hip or knee arthroplasty. As for concurrent validity, the correlation between both surveys and the Expectation WOMAC was moderate confirming that the same construct was determined. However, patients scored systematically lower on the Expectation WOMAC compared to the Dutch Expectation Surveys. Research on patients' expectations before total hip and knee replacement has only been performed in a limited amount of countries. With the Dutch Expectations Surveys it is now possible to determine patients' expectations in another culture and healthcare setting.

One strategy to foster adoption of computerized provider order entry (CPOE) by physicians is the monthly distribution of a list identifying the number and use rate percentage of orders entered electronically versus on paper by each physician in the facility. Physicians care about CPOE use rate reports because they support the patient safety and quality improvement objectives of CPOE implementation. Certain physician groups are also motivated because they participate in contracted financial and performance arrangements that include incentive payments or financial penalties for meeting (or failing to meet) a specified CPOE use rate target. Misattribution of order sources can hinder accurate measurement of individual physician CPOE use and can thereby undermine providers' confidence in their reported performance, as well as their motivation to utilize CPOE. Misattribution of order sources also has significant patient safety, quality, and medicolegal implications. This analysis sought to evaluate the magnitude and sources of misattribution among hospitalists with high CPOE use and, if misattribution was found, to formulate strategies to prevent and reduce its recurrence, thereby ensuring the integrity and credibility of individual and facility CPOE use rate reporting. A detailed manual order source review and validation of all orders issued by one hospitalist group at a midsize community hospital was conducted for a one-month study period. We found that a small but not dismissible percentage of orders issued by hospitalists-up to 4.18 percent (95 percent confidence interval, 3.84-4.56 percent) per month-were attributed inaccurately. Sources of misattribution by department or function were as follows: nursing, 42 percent; pharmacy, 38 percent; laboratory, 15 percent; unit clerk, 3 percent; and radiology, 2 percent. Order management and protocol were the most common correct order sources that were incorrectly attributed. Order source misattribution can negatively affect

Modifying alcohol expectancies of Hispanic children: examining the effects of expectancy-targeted, developmentally congruous prevention videos.

Children's expectations about the effects of alcohol consumption are known to predict the amount of alcohol they consume as adults. Previous research has used videotaped interventions to modify children's alcohol expectancies and found that puppet actors had the expected effect of decreasing children's positive alcohol expectancies, whereas adult actors did not. The current study sought to enhance the methods and outcomes of previous research by developing brief prevention videos that focus on pre-selected negative and sedating alcohol expectancies and include youth actors and age-relevant scenarios. Using a 2 × 2 factorial design (actor's age [youth or adult] × scenario relevance [youth or adult]), we examined the alcohol expectancies of 183 Hispanic third-, fourth-, and fifth-grade students (50% girls) in a public school setting. Expectancies were assessed before, immediately following the intervention, and 1 month later. The intervention consisted of four 8-minute videos based on beliefs associated with expectancies related to low alcohol consumption and a control group video about school bus safety. Positive alcohol expectancies were significantly lower directly after the intervention than at baseline. At 1-month follow-up, this effect decreased but was still significant. The current study adds to existing findings that expectancies can be modified in children, using interventions that are extremely brief, low-cost, and linked to research in children's cognitive and social development. In addition, it appears that children of different ages and genders respond differently to varying components of prevention media.

Full Text Available This paper sheds light on the link between achievement goals, motivation, and parental expectations in a sample of 600 students attending higher education institutions in Kosovo. Aside from exploring the stipulated link between the constructs, the research aims to discover whether cultural differences mediate expected results. The results proved that the mastery of goals positively correlates to intrinsic motivation in addition to which curiosity as a subscale of intrinsic motivation positively predicted preferences for the mastery of goals. As expected, performance-approach and performance-avoidance goals, correlated to extrinsic motivation with extrinsic motivation, successfully predict preferences for both types of performance goals. The data proved that among students in Kosovo, all types of goals correlated to intrinsic motivation. Achievement goals were differentiated in extrinsic motivation with mastery goals correlating rather weakly to only one subscale of extrinsic motivation.

Neural correlates of rhythmic expectancy

Full Text Available Temporal expectancy is thought to play a fundamental role in the perception of rhythm. This review summarizes recent studies that investigated rhythmic expectancy by recording neuroelectric activity with high temporal resolution during the presentation of rhythmic patterns. Prior event-related brain potential (ERP studies have uncovered auditory evoked responses that reflect detection of onsets, offsets, sustains,and abrupt changes in acoustic properties such as frequency, intensity, and spectrum, in addition to indexing higher-order processes such as auditory sensory memory and the violation of expectancy. In our studies of rhythmic expectancy, we measured emitted responses - a type of ERP that occurs when an expected event is omitted from a regular series of stimulus events - in simple rhythms with temporal structures typical of music. Our observations suggest that middle-latency gamma band (20-60 Hz activity (GBA plays an essential role in auditory rhythm processing. Evoked (phase-locked GBA occurs in the presence of physically presented auditory events and reflects the degree of accent. Induced (non-phase-locked GBA reflects temporally precise expectancies for strongly and weakly accented events in sound patterns. Thus far, these findings support theories of rhythm perception that posit temporal expectancies generated by active neural processes.

SGTCS is responsible for monitoring and reporting the performance of the SG equipment. Performance monitoring (PM) has been implemented in most important safeguards equipment operating unattended in nuclear facilities. Inspectors acquire equipment performance data in facilities. After inspection, the data package is submitted to SGTCS for processing and analysis. The performance data is used for identification of systems or components, which should be changed in the field and for identification of modules which, should be diagnosed at HQ in order to determine the cause of failure. Moreover, the performance data is used for preventive maintenance and spares distribution planning, and to provide statistics for official reports and management decision making. An important part of the performance monitoring is reporting. Equipment performance reports contain information about equipment inventory, utilization, failure types, failure distribution, and reliability. Trends in performance are given in graphical form in cases, where past data is available. Reliability estimates such as expected times between failures are provided. The automated reporting tools are obtainable through EMIS database application. (author)

Karimi, Faezeh; Poo, Danny C C; Tan, Yung Ming

2015-02-01

Prior research on information systems (IS) shows that users' attitudes and continuance intentions are associated with their satisfaction with information systems. As such, the increasing amount of investments in clinical information systems (CIS) signifies the importance of understanding CIS end users' (i.e., clinicians) satisfaction. In this study, we develop a conceptual framework to identify the cognitive determinants of clinicians' satisfaction formation. The disconfirmation paradigm serves as the core of the framework. The expectations and needs congruency models are the two models of this paradigm, and perceived performance is the basis of the comparisons in the models. The needs and expectations associated with the models are also specified. The survey methodology is adopted in this study to empirically validate the proposed research model. The survey is conducted at a public hospital and results in 112 and 203 valid responses (56% and 98% response rates) from doctors and nurses respectively. The partial least squares (PLS) method is used to analyze the data. The results of the study show that perceived CIS performance is the most influential factor on clinicians' (i.e., doctors and nurses) satisfaction. Doctors' expectations congruency is the next significant determinant of their satisfaction. Contrary to most previous findings, nurses' expectations and expectations congruency do not show a significant effect on their satisfaction. However, the needs congruency is found to significantly affect nurses' satisfaction. Copyright © 2014 Elsevier Inc. All rights reserved.

Full Text Available Introduction: Patient-centred healthcare is becoming a more significant success factor in the design of integrated healthcare systems. The objective of this study is to structure a patient-relevant hierarchy of needs and expectations for the design of organised healthcare delivery systems. Methods: A questionnaire with 84 items was conducted with N = 254 healthcare experts and N = 670 patients. Factor analyses were performed using SPSS©18. The number of factors retained was controlled by Kaiser's criterion, validation of screeplots and interpretability of the items. Cronbach's α was used to assess the internal consistency of the subscales. Results: Exploratory factor analysis led to 24 factors in the expert sample and 20 in the patient sample. After analysing the screeplots, confirmatory factor analyses were computed for 7-factor solutions accounting for 42.963% of the total variance and Kaiser–Meyer–Olkinof 0.914 for the patients (experts: 38.427%, Kaiser–Meyer–Olkin = 0.797. Cronbach's α ranged between 0.899 and 0.756. Based on the analysis, coordinated care could be differentiated into seven dimensions: access, data and information, service and infrastructure, professional care, interpersonal care, individualised care, continuity and coordination. Conclusion and Discussion: The study provides insight into patient and experts expectations towards the organisation of integrated healthcare delivery systems. If providers and payers can take into account patient needs and expectations while implementing innovative healthcare delivery systems, greater acceptance and satisfaction will be achieved. In the best case, this will lead to better adherence resulting in better clinical outcomes.

2007-01-01

Close to converged energies and expectation values for e + PsH are computed using a ground-state wave function consisting of 1500 explicitly correlated Gaussians. The best estimate of the e + PsH ∞ energy was -0.810 254 hartrees, which has a binding energy of 0.021 057 hartrees against dissociation into e + +PsH. The 2γ annihilation rate was 2.7508x10 9 s -1 . Binding energies and annihilation rates are also given for the different finite-mass variants of e + PsH. Comparisons between expectation values for e + PsH and PsH provide compelling evidence that the e + PsH ground state can be regarded as consisting of a weakly bound positron orbiting the PsH ground state

Most payment methods in healthcare stimulate volume-driven care, rather than value-driven care. Value-based payment methods such as Pay-For-Performance have the potential to reduce costs and improve quality of care. Ideally, outcome indicators are used in the assessment of providers' performance. The aim of this paper is to describe the feasibility of assessing and comparing the performances of providers using a comprehensive set of quality and cost data. We had access to unique and extensive datasets containing individual data on PROMs, PREMs and costs of physiotherapy practices in Dutch primary care. We merged these datasets at the patient-level and compared the performances of these practices using case-mix corrected linear regression models. Several significant differences in performance were detected between practices. These results can be used by both physiotherapists, to improve treatment given, and insurers to support their purchasing decisions. The study demonstrates that it is feasible to compare the performance of providers using PROMs and PREMs. However, it would take an extra effort to increase usefulness and it remains unclear under which conditions this effort is cost-effective. Healthcare providers need to be aware of the added value of registering outcomes to improve their quality. Insurers need to facilitate this by designing value-based contracts with the right incentives. Only then can payment methods contribute to value-based healthcare and increase value for patients.

Understanding the complex relationships among factors that may predict the outcomes of young adults with autism spectrum disorder (ASD) is of utmost importance given the increasing population undergoing and anticipating the transition to adulthood. With a sample of youth with ASD (n = 1170) from the National Longitudinal Transition Study-2, structural equation modeling techniques were used to test parent expectations as a mediator of young adult outcomes (i.e., employment, residential independence, social participation) in a longitudinal analysis. The mediation hypothesis was confirmed; family background and functional performance variables significantly predicted parent expectations which significantly predicted outcomes. These findings add context to previous studies examining the role of parent expectations on young adult outcomes and inform directions for family-centered interventions and future research.

Negative reinforcement eating expectancies, emotion dysregulation, and symptoms of bulimia nervosa.

Hayaki, Jumi

2009-09-01

Research suggests that emotion dysregulation or difficulties in the modulation of emotional experience constitute risk for eating disorders. Recent work has also highlighted the role of certain eating-related cognitions, specifically expectations of negative emotional reinforcement from eating, in the development of disturbed eating patterns. However, it is unclear whether these expectancies are merely a dimension of a general inability to regulate emotions effectively or rather a unique cognitive-affective risk factor for the development of an eating disorder. This study examines the unique contribution of eating expectancies to symptoms of bulimia nervosa (BN) after controlling for two dimensions of emotion dysregulation (alexithymia and experiential avoidance) previously implicated in the phenomenology of eating disorders. Participants were 115 undergraduate women who self-reported demographics, alexithymia, experiential avoidance, eating expectancies, and symptoms of BN. Eating expectancies uniquely contributed 12.4% of the variance in symptoms of BN, F(2, 108) = 11.74, p symptoms of BN. These results suggest that individuals who expect eating to provide emotional relief may be especially susceptible to disordered eating. Findings are discussed in terms of emotional risk models and clinical interventions for BN.

An fMRI investigation of expectation violation in magic tricks

Amory H. Danek

2015-02-01

Full Text Available Magic tricks violate the expected causal relationships that form an implicit belief system about what is possible in the world around us. Observing a magic effect seemingly invalidates our implicit assumptions about what action causes which outcome. We aimed at identifying the neural correlates of such expectation violations by contrasting 24 video clips of magic tricks with 24 control clips in which the expected action-outcome relationship is upheld. Using fMRI, we measured the brain activity of 25 normal volunteers while they watched the clips in the scanner. Additionally, we measured the professional magician who had performed the magic tricks under the assumption that, in contrast to naïve observers, the magician himself would not perceive his own magic tricks as an expectation violation. As the main effect of magic – control clips in the normal sample, we found higher activity for magic in the head of the caudate nucleus bilaterally, the left inferior frontal gyrus and the left anterior insula. As expected, the magician’s brain activity substantially differed from these results, with mainly parietal areas (supramarginal gyrus bilaterally activated, supporting our hypothesis that he did not experience any expectation violation. These findings are in accordance with previous research that has implicated the head of the caudate nucleus in processing changes in the contingency between action and outcome, even in the absence of reward or feedback.

The influence of student ethnicity on teacher expectations and teacher perceptions of warmth and competence

Full Text Available Background. Previous research shows that incorrect teacher expectations about students can affect students’ academic success. Moreover, students’ ethnicity was found to be one of the most influential characteristics affecting teacher expectations, which can be based on ethnic stereotypes. Most studies test this relationship by comparing teacher expectations of multiple ethnic groups; however, we propose here another perspective, assuming that the connection between ethnic stereotypes and expectations may be determined by the content of the stereotypes. Objective. This study examines the influence of students’ ethnicity on teacher expectations and stereotypes, as well as the relationship of teacher expectations and stereotypes toward ethnic minority students, by including the stereotype content model in the analysis. Design. Thirty-four primary school teachers participated in the experiment in which they analyzed six fictional profiles of students, two of which were experimental. The experimental profiles contained identical information (annual school grade, a teacher testimonial, gender, but differed in names of the students and their parents, and in their migration background. Thus, we manipulated only the information related to ethnicity and migration history of two students. Results. Teacher expectations about the performance of minority students were always unfavorable compared with expectations about the performance of the majority students, but their expectations about the abilities of minority and majority students, which include teachers’ beliefs about students’ educational skills, attitudes and motivation, and capacity for school work, were mixed. We also discovered that the teacher expectations were positively related to perceptions of competence and not to perceptions of warmth. However, the minority student was evaluated by teachers as just as warm and competent as the majority. Conclusion. This study shows the relevance of

Although initially developed for medical purposes, synthetic cannabinoids have also been consumed for recreational purposes. To evaluate whether agreement with positive and negative outcome expectancies differed for synthetic cannabinoids versus botanical marijuana, and assess reported reasons for using synthetic cannabinoids. Using a web-based recruitment and data collection procedure, 186 adults who had used both synthetic cannabinoids and botanical marijuana and 181 adults who had used botanical marijuana but not synthetic cannabinoids, completed measures of outcome expectancies and other relevant questionnaires. A significant interaction revealed that participants who had used both synthetic cannabinoids and botanical marijuana indicated lower agreement with positive expectancies for synthetic cannabinoids, and higher agreement with positive expectancies for botanical marijuana, than did those participants who used only botanical marijuana. There was no interaction between type of drug and use history on agreement with negative expectancies, and participants agreed more strongly with negative outcome expectancies for synthetic cannabinoids than for botanical marijuana whether they had used one or both types of these drugs. The most frequently provided reasons for using synthetic cannabinoids included availability, perceived legality, cost, curiosity, and social interaction. Given growing public acceptance of recreational and medical marijuana, coupled with negative perceptions and increasing regulation of synthetic cannabinoid compounds, botanical marijuana is likely to remain more available and more popular than synthetic cannabinoids.

Previous research has shown that ideas which violate our expectations, such as schema-inconsistent concepts, enjoy privileged status in terms of memorability. In our study, memory for concepts that violate cultural (cultural schema-level) expectations (e.g., ‘‘illiterate teacher’’, ‘‘wooden bottle...... expectations and with intuitive concepts (e.g., ‘‘galloping pony’’, ‘‘drying orchid’’, or ‘‘convertible car’’), in both immediate recall, and delayed recognition tests. Importantly, concepts related to agents showed a memory advantage over concepts not pertaining to agents, but this was true only...... for expectation-violating concepts. Our results imply that intuitive, everyday concepts are equally attractive and memorable regardless of the presence or absence of agents. However, concepts that violate our expectations (cultural-schema or domain-level) are more memorable when pertaining to agents (humans...

Public University Students' Expectations: An Empirical Study Based on the Stakeholders Theory

Emerson Wagner MAINARDES

2012-02-01

Full Text Available In accordance with the importance that the student stakeholder represents to universities, the objective of this research project was to identify and classify the leading expectations of students at public universities. In order to achieve this, the study adopted both the premises of Stakeholder Theory and the approaches of earlier studies on the management of university stakeholders. This empirical study began with an exploratory study of students, at one university, to identify their expectations this resulting in a list of a total of twenty-five confirmed expectations. This provided the basis for the subsequent quantitative study involving students attending eleven Portuguese public universities. Through recourse to an online questionnaire, we obtained 1,669 correctly completed surveys that provided the input for data analysis deploying descriptive statistical processes and multiple linear regressions. Our findings show that the most important student expectations are the academic level of demand, the university’s connections with the employment market, student personal self-fulfillment and the prevailing university environment. According to students, these expectations should gain priority attention by university managers, once they consider them the most relevant aspects to the relationship between the student and the university.

Expectation values in quantum gravity

International Nuclear Information System (INIS)

Jordan, R.D.

1986-01-01

The purpose of this dissertation is to develop new methods for calculating expectation values of field operators, in situations where particle creation is important. The goal is to apply these techniques to quantum gravity, to see if the initial singularity in the universe might be avoided in the quantum theory. Standard effective action theory is modified to produce effective field equations satisfied by the expectation value of the field in an in state, as opposed to the usual in-out amplitude. Diagrammatic rules are found for calculation of the new field equations, and are used to show that the equations are real and causal up to two loop order. The theory also provides a simple check of unitarity, which is carried out, again up to two loops. Just as the standard effective field equations can be derived by analytic continuation from a theory defined in Euclidean space, so can the modified equations be obtained from a modified contour rotation of the Euclidean theory. This result is used to prove a recent conjecture which yields a simple rule for finding the real, causal equations. The new formalism is applied to two gravitational systems. First, the stability of flat space time is studied by finding the equation satisfied by small perturbations of Minkowski space

Measuring bank performance solely on the basis of profitability conveys significant information about past performance, but may provide little information about expectations for future performance. Therefore, this paper relies on a much broader definition of performance and introduces a scorecard where performance is measured on the basis of four performance criteria: (i) profitability; (ii) risk; (iii) market power, and (iv) efficiency. We use this scorecard to compare the performance of maj...

Expectancies as core features of mental disorders.

Rief, Winfried; Glombiewski, Julia A; Gollwitzer, Mario; Schubö, Anna; Schwarting, Rainer; Thorwart, Anna

2015-09-01

Expectancies are core features of mental disorders, and change in expectations is therefore one of the core mechanisms of treatment in psychiatry. We aim to improve our understanding of expectancies by summarizing factors that contribute to their development, persistence, and modification. We pay particular attention to the issue of persistence of expectancies despite experiences that contradict them. Based on recent research findings, we propose a new model for expectation persistence and expectation change. When expectations are established, effects are evident in neural and other biological systems, for example, via anticipatory reactions, different biological reactions to expected versus unexpected stimuli, etc. Psychological 'immunization' and 'assimilation', implicit self-confirming processes, and stability of biological processes help us to better understand why expectancies persist even in the presence of expectation violations. Learning theory, attentional processes, social influences, and biological determinants contribute to the development, persistence, and modification of expectancies. Psychological interventions should focus on optimizing expectation violation to achieve optimal treatment outcome and to avoid treatment failures.

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

Science.gov (United States)

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.

Patients' knowledge and expectations regarding dental implants: assessment by questionnaire.

Rustemeyer, J; Bremerich, A

2007-09-01

Today, modern implant dentistry appeals to a wide population, but the decision for and the success of implants depend on the knowledge and expectations of patients. The aim of this study was, with the help of a questionnaire, to evaluate the level of patient knowledge before a professional consultation was performed, and hence to be better prepared in the interests of patient awareness. Fifty-eight percent of 315 patients questioned thought that implants require the same care as natural teeth, 61% expected an additional payment of 2000 Euro or less, 80% held the function of an implant-supported overdenture as very important and 54% attached great importance to the aesthetics. The expectations that patients have for an implant-supported set are high in contrast to their willingness to make additional payments. There are still misconceptions regarding costs, and these must be resolved individually in practice.

Full Text Available Abstract Background Funding for research is under pressure to be accountable in terms of benefits and translation of research findings into practice and policy. Primary health care research has considerable potential to improve health care in a wide range of settings, but little is known about the extent to which these impacts actually occur. This study examines the impact of individual primary health care research projects on policy and practice from the perspective of Chief Investigators (CIs. Methods The project used an online survey adapted from the Buxton and Hanney Payback Framework to collect information about the impacts that CIs expected and achieved from primary health care research projects funded by Australian national competitive grants. Results and Discussion Chief Investigators (CIs provided information about seventeen completed projects. While no CI expected their project to have an impact in every domain of the framework used in the survey, 76% achieved at least half the impacts they expected. Sixteen projects had published and/or presented their work, 10 projects included 11 doctorate awards in their research capacity domain. All CIs expected their research to lead to further research opportunities with 11 achieving this. Ten CIs achieved their expectation of providing information for policy making but only four reported their research had influenced policy making. However 11 CIs achieved their expectation of providing information for organizational decision making and eight reported their research had influenced organizational decision making. Conclusion CIs reported that nationally funded primary health care research projects made an impact on knowledge production, staff development and further research, areas within the realm of influence of the research team and within the scope of awareness of the CIs. Some also made an impact on policy and organizational decision-making, and on localized clinical practice and service

We report a study designed to investigate the influence of the weight of the container on expected satiety prior to tasting the food within and on the perceived density of the food and any feelings of fullness expected to follow consumption (expected satiation). The results demonstrate that the contents of a heavier container are expected to be more satiating than when exactly the same contents are presented in a visually-identical, but physically lighter, container (even before the food has been tasted). In addition, we were able to validate a "weight-density" illusion, since the weight of the container was shown to influence the perceived density of the sample. Put simply, the heavier the container, the denser the food sample was perceived to be. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available Acid soil area is one of the areas broadly available in Indonesia. However, the complexity of acid soil may lead to low soybean productivity. Hence, soybean variety which is adaptive to acid soil is needed. The objective of this research was to find out expected lines adaptive to acid soil. A number of ten soybean lines and two check varieties were grown in Natar Research Station in dry season II, 2011. This research applied randomized completely block design with four replications. Results showed that 7 of 10 soybean lines had grain yield higher than those of two check varieties. The three lines with the highest grain yield were Tgm/Anj-957, Tgm/Anj-908 and Tgm/Anj-932 with grain yield 1.83, 1.74, and 1.65 t ha-,1 respectively. Tanggamus variety had grain yield higher than Wilis. The highest grain yield line, Tgm/Anj-957, was also supported by the highest number of pods per plant up to 68 pod. Line of Tgm/Anj-995 was the line with the largest seed size, i.e. 16 g per 100 seeds.

Xiang, Ping; McBride, Ron; Guan, Jianmin; Solmon, Melinda

2003-03-01

This study examined children's motivation in elementary physical education within an expectancy-value model developed by Eccles and her colleagues. Four hundred fourteen students in second and fourth grades completed questionnaires assessing their expectancy-related beliefs, subjective task values, and intention for future participation in physical education. Results indicated that expectancy-related beliefs and subjective task values were clearly distinguishable from one another across physical education and throwing. The two constructs were related to each other positively. Children's intention for future participation in physical education was positively associated with their subjective task values and/or expectancy-related beliefs. Younger children had higher motivation for learning in physical education than older children. Gender differences emerged and the findings provided empirical evidence supporting the validity of the expectancy-value model in elementary physical education.

Since it is desired to enhance availability and safety of nuclear power plants operation and maintenance by removing human factor, there are many researches and developments for intelligent operation or diagnosis using artificial intelligence (AI) technique. We have been developing an autonomous operation and maintenance system for nuclear power plants by substituting AI's and intelligent robots. It is indispensable to use various and large scale knowledge relative to plant design, operation, and maintenance, that is, whole life cycle data of the plant for the autonomous nuclear power plant. These knowledge must be given to AI system or intelligent robots adequately and opportunely. Moreover, it is necessary to insure real time operation using the large scale knowledge base for plant control and diagnosis performance. We have been studying on the large scale and real time knowledge base system for autonomous plant. In the report, we would like to present the basic concept and expecting performance of the knowledge base for autonomous plant, especially, autonomous control and diagnosis system. (author)

Heterogeneous inflation expectations and learning

OpenAIRE

Madeira, Carlos; Zafar, Basit

2012-01-01

Using the panel component of the Michigan Survey of Consumers, we estimate a learning model of inflation expectations, allowing for heterogeneous use of both private information and lifetime inflation experience. “Life-experience inflation” has a significant impact on individual expectations, but only for one-year-ahead inflation. Public information is substantially more relevant for longer-horizon expectations. Even controlling for life-experience inflation and public information, idiosyncra...

Decennial trends and inequalities in healthy life expectancy: The HUNT Study, Norway.

Norway is experiencing a rising life expectancy combined with an increasing dependency ratio - the ratio of those outside over those within the working force. To provide data relevant for future health policy we wanted to study trends in total and healthy life expectancy in a Norwegian population over three decades (1980s, 1990s and 2000s), both overall and across gender and educational groups. Data were obtained from the HUNT Study, and the Norwegian Educational Database. We calculated total life expectancy and used the Sullivan method to calculate healthy life expectancies based on self-rated health and self-reported longstanding limiting illness. The change in health expectancies was decomposed into mortality and disability effects. During three consecutive decades we found an increase in life expectancy for 30-year-olds (~7 years) and expected lifetime in self-rated good health (~6 years), but time without longstanding limiting illness increased less (1.5 years). Women could expect to live longer than men, but the extra life years for females were spent in poor self-rated health and with longstanding limiting illness. Differences in total life expectancy between educational groups decreased, whereas differences in expected lifetime in self-rated good health and lifetime without longstanding limiting illness increased. The increase in total life expectancy was accompanied by an increasing number of years spent in good self-rated health but more years with longstanding limiting illness. This suggests increasing health care needs for people with chronic diseases, given an increasing number of elderly. Socioeconomic health inequalities remain a challenge for increasing pensioning age.

The main goal of the study is to examine the evolution of players' perception of cohesion and efficacy over the season and their relation with success expectations. The research sample comprised 146 male soccer players, aged between 15 and 19 years (M = 16.96, SD = .76). Diverse instruments were used to measure cohesion, perceived efficacy, and success expectations. The most noteworthy results show that players whose expectations do not match the team's final performance will experience a negative evolution of their levels of perceived cohesion and efficacy, whereas players whose expectations at the start of the season match the team's final performance in the classification will maintain their degree of perceived cohesion and efficacy. The main conclusion of the study is that coaches and sport psychologists should attempt to clarify the players' basic goals of the season to create expectations that match what is expected from the team.

Hurd, Michael; van Rooij, Maarten; Winter, Joachim

2011-04-01

Despite its importance for the analysis of life-cycle behavior and, in particular, retirement planning, stock ownership by private households is poorly understood. Among other approaches to investigate this puzzle, recent research has started to elicit private households' expectations of stock market returns. This paper reports findings from a study that collected data over a two-year period both on households' stock market expectations (subjective probabilities of gains or losses) and on whether they own stocks. We document substantial heterogeneity in financial market expectations. Expectations are correlated with stock ownership. Over the two years of our data, stock market prices increased, and expectations of future stock market price changes also increased, lending support to the view that expectations are influenced by recent stock gains or losses.

1993-11-01

This technical report has been developed to address the survivability of telecommunications networks including services. It responds to the need for a common understanding of, and assessment techniques for network survivability, availability, integrity, and reliability. It provides a basis for designing and operating telecommunications networks to user expectations for network survivability and a foundation for continuing industry activities in the subject area. This report focuses on the survivability of both public and private networks and covers a wide range of users. Two frameworks are established for quantifying and categorizing service outages, and for classifying network survivability techniques and measures. The performance of the network survivability techniques is considered; however, recommended objectives are not established for network survivability performance.

Full Text Available Background: There is no clear data on the adherence of emergency medical services (EMS paramedics and hospital staff rather than those working in poisoning centers to the guidelines for managing acutely poisoned patients in developing countries. Methods: During a 6-month period, all EMS-managed poisoned patients along with those initially managed in a non-poisoning center before being referred to a poisoning hospital in Tehran, Iran, were instructed. Then the indications for administrating the activated charcoal (AC as well as performing gastric lavage (GL and tracheal intubation were studied and compared to the recommended guidelines. Results: A total of 3347 cases, including 1859 males (55.6%, were evaluated. There were significant differences between expected and performed endotracheal intubations in both EMS and other medical centers (P-value = 0.002 and 0.001, respectively as well as the administration of GL and AC in other medical centers (P-values= 0.003 and 0.03, respectively. Conclusion: More extensive educational programs should be established to improve the preliminary management of poisoned patients performed by EMS paramedics and staff of hospitals other than poisoning centers.

Resuscitation and life support skills training comprises a significant proportion of continuing education programming for health professionals. The purpose of this study was to explore the perceptions and attitudes of certified resuscitation providers toward the retention of resuscitation skills, regular skills updating, and methods for enhancing retention. A mixed-methods, explanatory study design was undertaken utilizing focus groups and an online survey-questionnaire of rural and urban health care providers. Rural providers reported less experience with real codes and lower abilities across a variety of resuscitation areas. Mock codes, practice with an instructor and a team, self-practice with a mannequin, and e-learning were popular methods for skills updating. Aspects of team performance that were felt to influence resuscitation performance included: discrepancies in skill levels, lack of communication, and team leaders not up to date on their skills. Confidence in resuscitation abilities was greatest after one had recently practiced or participated in an update or an effective debriefing session. Lowest confidence was reported when team members did not work well together, there was no clear leader of the resuscitation code, or if team members did not communicate. The study findings highlight the importance of access to update methods for improving providers' confidence and abilities, and the need for emphasis on teamwork training in resuscitation. An eclectic approach combining methods may be the best strategy for addressing the needs of health professionals across various clinical departments and geographic locales.

Silvia TAMAYO

2017-10-01

Full Text Available Conversational Pedagogical Agents are interactive systems that teach students by assuming the role of teacher, student or companion through a natural language dialogue. If has been investigated a lot on the domains in which the agents can be used, the results in terms of educational effectiveness and level of satisfaction and motivation of the students. However, in the literature, there are not many examples of studies that reveal the opinion of school teachers on this type of educational technology. In this paper, we provide the results of a survey of 82 teachers to know what they expect from the agents. The following research questions will be answered: Q1 Do you know this educational technology? Q2 If so, are teachers used to integrate this type of technology in the classroom? and, P3 If teachers could design the agent, what characteristics do they consider to be the most appropriate? How should the agent react to different situations? From the results gathered, it is expected to provide information to all researchers, designers and teachers who want to integrate this type of educational technology in their classroom..

Customer experiences and expectations

International Nuclear Information System (INIS)

Morton, C. R.

1997-01-01

Customer experiences and expectations from competition and cogeneration in the power industry were reviewed by Charles Morton, Director of Energy at CPC International, by describing Casco's decision to get into cogeneration in the early 1990s in three small corn milling plants in Cardinal, London and Port Colborne, Ontario, mainly as result of the threat of a 40 per cent increase in power prices. He stressed that cost competitiveness of cogeneration is entirely site-specific, but it is generally more attractive in larger facilities that operate 24 hours a day, where grid power is expensive or unreliable. Because it is reliable, cogeneration holds out the prospect of increased production-up time, as well as offering a hedge against higher energy costs, reducing the company's variable costs when incoming revenues fall short of costs, and providing an additional tool in head-to-head competition

Full Text Available BACKGROUND The gamma-Gompertz multiplicative frailty model is the most common parametric modelapplied to human mortality data at adult and old ages. The resulting life expectancy hasbeen calculated so far only numerically. OBJECTIVE Properties of the gamma-Gompertz distribution have not been thoroughly studied. The focusof the paper is to shed light onto its first moment or, demographically speaking, characterizelife expectancy resulting from a gamma-Gompertz force of mortality. The paperprovides an exact formula for gamma-Gompertz life expectancy at birth and a simplerhigh-accuracy approximation that can be used in practice for computational convenience.In addition, the article compares actual (life-table to model-based (gamma-Gompertzlife expectancy to assess on aggregate how many years of life expectancy are not captured(or overestimated by the gamma-Gompertz mortality mechanism. COMMENTS A closed-form expression for gamma-Gomeprtz life expectancy at birth contains a special(the hypergeometric function. It aids assessing the impact of gamma-Gompertz parameterson life expectancy values. The paper shows that a high-accuracy approximation canbe constructed by assuming an integer value for the shape parameter of the gamma distribution.A historical comparison between model-based and actual life expectancy forSwedish females reveals a gap that is decreasing to around 2 years from 1950 onwards.Looking at remaining life expectancies at ages 30 and 50, we see this gap almost disappearing.

A systematic approach to organizational expectations

International Nuclear Information System (INIS)

McGarry, M.; Hill, T.

1996-01-01

This paper describes a new approach to human performance management that we at OHN are testing. We believe that our attainment of nuclear excellence has been limited by an over-emphasis on the technological component of improvement as compared to the human contribution factor. To achieve legitimate success in technological innovation, we feel that it must be coupled with innovation in human performance management. Our attempts to do so involve: developing Nuclear Excellence right into the job; regularly measuring job behaviours as an assessment of the effectiveness of our system; and establishing close internal partnerships to facilitate this system of human performance management. Explicit definition and measurement of job behaviour are dominant elements in our process. We employed the following steps to achieve an acceptable, measurable job analysis: Reviewed internal and international criteria to define a set of expected behaviours; attained management consensus about the meaning and links to the workplace of these behaviours; solicited feedback from those who perform these behaviours; created a computer-based survey to collect information on actual conditions and likely root causes; and defined the strategic information that the survey would deliver. As well, the links between this process and other Human Resources functions were identified for future investigation. 3 figs

Background In a previous study, we provided evidence that a decline in fine particulate matter (PM2.5) air pollution during the period between 2000 and 2007 was associated with increased life expectancy in 545 counties in the United States. In this article, we investigated which chemical constituents of PM2.5 were the main drivers of the observed association. Methods We estimated associations between temporal changes in seven major components of PM2.5 (ammonium, sulfate, nitrate, elemental carbon matter, organic carbon matter, sodium, and silicon) and temporal changes in life expectancy in 95 counties between 2002 and 2007. We included US counties that had adequate chemical components of PM2.5 mass data across all seasons. We fitted single pollutant and multiple pollutant linear models, controlling for available socioeconomic, demographic, and smoking variables and stratifying by urban and nonurban counties. Results In multiple pollutant models, we found that: (1) a reduction in sulfate was associated with an increase in life expectancy; and (2) reductions in ammonium and sodium ion were associated with increases in life expectancy in nonurban counties only. Conclusions Our findings suggest that recent reductions in long-term exposure to sulfate, ammonium, and sodium ion between 2002 and 2007 are associated with improved public health. PMID:25906366

2018-02-01

More than 35 000 umbilical cord blood (UCB) transplants have been performed worldwide, prompting the development of private and public banks to collect and store UCB cells. We hypothesized that pediatricians, who are uniquely poised to discuss UCB banking (UCBB) during prenatal or sibling visits, rarely do so. Through distribution of a 26-question electronic survey to general and subspecialty pediatric providers, we assessed baseline knowledge and conversations about UCBB. A total of 473 providers completed the survey; only 22% of physicians ever discussed UCBB with expectant parents. The majority responded that autologous UCB transplants were indicated in malignant (73%) and nonmalignant (61%) conditions; however, these are rare indications. Providers practicing >10 years were more likely to address UCBB ( P ≤ .001), whereas younger and female general pediatric providers were significantly less likely ( P < .001). Overall, pediatric providers rarely speak to families about UCBB, and we believe that they can be better informed to its current clinical utility.

Full Text Available Drawing appropriate diagrams is a useful problem solving heuristic that can transform a problem into a representation that is easier to exploit for solving it. One major focus while helping introductory physics students learn effective problem solving is to help them understand that drawing diagrams can facilitate problem solution. We conducted an investigation in which two different interventions were implemented during recitation quizzes in a large enrollment algebra-based introductory physics course. Students were either (i asked to solve problems in which the diagrams were drawn for them or (ii explicitly told to draw a diagram. A comparison group was not given any instruction regarding diagrams. We developed rubrics to score the problem solving performance of students in different intervention groups and investigated ten problems. We found that students who were provided diagrams never performed better and actually performed worse than the other students on three problems, one involving standing sound waves in a tube (discussed elsewhere and two problems in electricity which we focus on here. These two problems were the only problems in electricity that involved considerations of initial and final conditions, which may partly account for why students provided with diagrams performed significantly worse than students who were not provided with diagrams. In order to explore potential reasons for this finding, we conducted interviews with students and found that some students provided with diagrams may have spent less time on the conceptual analysis and planning stage of the problem solving process. In particular, those provided with the diagram were more likely to jump into the implementation stage of problem solving early without fully analyzing and understanding the problem, which can increase the likelihood of mistakes in solutions.

Despite recommendations that women give birth with a skilled birth attendant (SBA), 70% of births in Guatemala occur outside health facilities with informally trained traditional birth attendants (TBAs). To increase SBA in rural, indigenous communities, a professional midwifery school accredited by the government is scheduled to open in 2017. Drawing from Filby's model on barriers to the successful integration of professional midwifery into health systems, this paper aims to identify threats - and facilitators-toward professional midwifery's re-introduction in Guatemala. To elucidate perceptions, attitudes and expectations towards professional midwifery, qualitative, in-depth interviews were conducted with 32 physicians, nurses, and TBAs in six health centers and with key decision makers and professional midwives (PMs) in Guatemala City. We conducted open and axial coding in Atlas.ti and performed normative comparisons of participants' attitudes, perceptions, and expectations with the National Vision for professional midwifery and relative comparisons within and across disciplinary subgroups. Unprompted, physicians, nurses and TBAs were unable to correctly define professional midwifery. Yet, when professional midwifery was defined for them, they expressed willingness to work with PMs, seeing them as a needed human resource, instrumental in providing intercultural care and strengthening facility relationships with TBAs. Some stakeholders anticipated resistance toward PMs due to provider turf issues. Notable differences in expectations among all groups included ideas for supervision of and by the PMs and the PM's role in monitoring women and conducting births in communities alongside TBAs. Facilitators to professional midwifery's success include national political will, stakeholders' uniformity of vision, and the potential for improved intercultural care. Barriers are mostly professional in nature, including impediments to autonomous practice by PMs, hierarchical

Overprotection and lowered expectations of persons with disabilities: the unforeseen consequences.

Science.gov (United States)

Sanders, Karen Y

2006-01-01

Lowered expectations and overprotection of the individual with a disability can cause lowered self esteem which can result in a life time of underachievement and failure to reach their full potential. Both lowered expectations and overprotection are forms of discrimination. Internalization of discrimination causes the person with a disability to believe that they are less capable than a person without a disability. Parents and care providers of children with disabilities may overprotect the child to shield them from harm; however this can actually cause more damage. Successful parenting skills are required to help children and adolescents develop a positive self concept and high self esteem. Guidelines have been developed to assist parents, educators and other professionals regarding the effects of overprotection and lowered expectations.

We investigated whether repeated consumption of a low-energy-dense (LED; 208 kJ/100 g) or high-energy-dense (HED; 645 kJ/100 g) soup modifies expectations relating to the satiating capacity of the food, and its subsequent intake. In study 1, participants consumed either a novel-flavoured LED (n 32; 21 (SD 1·6) years, BMI 21·4 (SD 1·6) kg/m(2)) or HED soup (n 32; 21 (SD 1·6) years, BMI 21·3 (SD 1·7) kg/m(2)). Soup was served in a fixed amount on days 1-4 and ad libitum on day 5. 'Expected satiation' was measured on days 1, 2 and 5. Expected satiation did not change after repeated consumption of the LED or HED soup. Ad libitum intake did not differ between the LED (461 (SD 213) g) and HED soup (391 (SD 164) g). Only on day 1, expected satiation was higher for the HED soup than for the LED soup (P = 0·03), suggesting a role for sensory attributes in expected satiation. In study 2, thirty participants (21 (SD 1·6) years, BMI 21·3 (SD 1·7) kg/m(2)) performed a single measurement of expected satiation of the LED and HED soup, and four commercially available types of soup. Ratings on sensory attributes were associated with expected satiation. Results on expected satiation coincided with those of study 1. Thickness and intensity of taste were independently associated with expected satiation. Expectations may initially rely on sensory attributes and previous experiences, and are not easily changed.

Etzel, K.T.; Howard, W.W.; Zgliczynski, J.B.

1992-05-01

This document discusses thermal performance envelopes which are used to specify steady-state design requirements for the systems of the Modular High Temperature Gas-Cooled Reactor to maximize plant performance reliability with optimized design. The thermal performance envelopes are constructed around the expected operating point accounting for uncertainties in actual plant as-built parameters and plant operation. The components are then designed to perform successfully at all points within the envelope. As a result, plant reliability is maximized by accounting for component thermal performance variation in the design. The design is optimized by providing a means to determine required margins in a disciplined and visible fashion

Expected Net Present Value, Expected Net Future Value, and the Ramsey Rule

Weitzman (1998) showed that when future interest rates are uncertain, using the expected net present value implies a term structure of discount rates that is decreasing to the smallest possible interest rate. On the contrary, using the expected net future value criteria implies an increasing term structure of discount rates up to the largest possible interest rate. We reconcile the two approaches by introducing risk aversion and utility maximization. We show that if the aggregate consumption ...

2003-06-01

This study investigates the effects of video lottery players' expectancies of winning on physiological and subjective arousal. Participants were assigned randomly to one of two experimental conditions: high and low winning expectancies. Participants played 100 video lottery games in a laboratory setting while physiological measures were recorded. Level of risk-taking was controlled. Participants were 34 occasional or regular video lottery players. They were assigned randomly into two groups of 17, with nine men and eight women in each group. The low-expectancy group played for fun, therefore expecting to win worthless credits, while the high-expectancy group played for real money. Players' experience, demographic variables and subjective arousal were assessed. Severity of problem gambling was measured with the South Oaks Gambling Screen. In order to measure arousal, the average heart rate was recorded across eight periods. Participants exposed to high as compared to low expectations experienced faster heart rate prior to and during the gambling session. According to self-reports, it is the expectancy of winning money that is exciting, not playing the game. Regardless of the level of risk-taking, expectancy of winning is a cognitive factor influencing levels of arousal. When playing for fun, gambling becomes significantly less stimulating than when playing for money.
