Wagner, Joan I J; Brooks, Denise; Urban, Ann-Marie

2018-01-01

Spirit at work (SAW) research emerged as a response to care provider determination to maintain a healthy and productive health care work environment, despite restructuring. The aim of this descriptive mixed-methods research is to present the care provider's perceptions of SAW. SAW is a holistic measure of care provider workplace outcomes, defined as the unique experience of individuals who are passionate about and energized by their work. A mixed group of licensed and unlicensed care providers in a continuing care workplace were surveyed. Eighteen Likert-type scale survey questions were further informed by two open-ended questions. Results indicated that unlicensed continuing care providers' perceptions of SAW are lower than licensed care providers. Responses suggest that open discussion between managers and team members, combined with structured workplace interventions, will lead to enhanced SAW and improved patient care. Further research on SAW within the continuing care workplace is required.

Multi-disciplinary optimization of aeroservoelastic systems

NASA Technical Reports Server (NTRS)

Karpel, Mardechay

1992-01-01

The purpose of the research project was to continue the development of new methods for efficient aeroservoelastic analysis and optimization. The main targets were as follows: to complete the development of analytical tools for the investigation of flutter with large stiffness changes; to continue the work on efficient continuous gust response and sensitivity derivatives; and to advance the techniques of calculating dynamic loads with control and unsteady aerodynamic effects. An efficient and highly accurate mathematical model for time-domain analysis of flutter during which large structural changes occur was developed in cooperation with Carol D. Wieseman of NASA LaRC. The model was based on the second-year work 'Modal Coordinates for Aeroelastic Analysis with Large Local Structural Variations'. The work on continuous gust response was completed. An abstract of the paper 'Continuous Gust Response and Sensitivity Derivatives Using State-Space Models' was submitted for presentation in the 33rd Israel Annual Conference on Aviation and Astronautics, Feb. 1993. The abstract is given in Appendix A. The work extends the optimization model to deal with continuous gust objectives in a way that facilitates their inclusion in the efficient multi-disciplinary optimization scheme. Currently under development is a work designed to extend the analysis and optimization capabilities to loads and stress considerations. The work is on aircraft dynamic loads in response to impulsive and non-impulsive excitation. The work extends the formulations of the mode-displacement and summation-of-forces methods to include modes with significant local distortions, and load modes. An abstract of the paper,'Structural Dynamic Loads in Response to Impulsive Excitation' is given in appendix B. Another work performed this year under the Grant was 'Size-Reduction Techniques for the Determination of Efficient Aeroservoelastic Models' given in Appendix C.

2014-01-01

Early retirement is an increasing problem in the construction industry. There is limited information about causes leading employees to leave working life early. We have compared construction workers present situation with their perception of future demands at work to avoid early retirement. All 87 employees in a medium-sized Norwegian construction company participated in the study. All were men and answered questionnaires on health and pain, work ability, mechanical exposure, psychosocial conditions, and demands regarding future working conditions. Most workers showed good work ability, irrespective of age. Many reported high levels of mechanical exposure at work. The level of musculoskeletal pain was higher in the middle-aged (30-50 year old) age groups and seniors aged over 50 years than among the youngest workers less than 30 years of age. All workers reported that good health was important for continued working. Most workers stated that future work must not be too physically demanding. Many workers reported relatively low job satisfaction; consequently an interesting job was rated as important for continuing work. Good social conditions were a high priority. According to the examined construction workers, good health and reduced levels of mechanical exposure at work are essential to avoid early retirement.

Steinlin, Célia; Dölitzsch, Claudia; Fischer, Sophia; Schmeck, Klaus; Fegert, Jörg M; Schmid, Marc

2016-01-01

Working in residential care is associated with high demands and high stress. As a result, employees may develop symptoms of burnout. These symptoms lead to absence from work and have a negative effect on the continuity and quality of the residential care. Until now, little is known about burnout risks in child welfare workers, although children and adolescents are especially dependent on continuous relationships and healthy caregivers. A better understanding of the relationship between burnout symptoms and work satisfaction may help to identify starting points for prevention and intervention. The present study assessed symptoms of burnout in a sample of 319 social education workers in residential care in Switzerland using the burnout-screening-scales (BOSS). Work satisfaction was assessed with a newly developed questionnaire based on concepts of trauma-sensitive care. The questionnaire was tested for reliability and factorial validity in the present study. In order to estimate the relationship between burnout symptoms and work satisfaction, correlations and relative risks were calculated. Almost one fifth (18 %) of the sample showed a risk of burnout. The principal component analysis of the questionnaire on work satisfaction revealed four factors: support by superiors, participation and transparency; communication and support within the team; gratification in the work; and institutional structures and resources. All four factors as well as the total score showed significant correlations with burnout symptoms. Among employees with a comparably lower work satisfaction, the risk of burnout was 5.4 times higher than among employees with a comparably higher work satisfaction. It is discussed how work satisfaction could be promoted and how, as a result, the quality and continuity of care for the children and adolescents could be improved.

High-power UV-LED degradation: Continuous and cycled working condition influence

NASA Astrophysics Data System (ADS)

Arques-Orobon, F. J.; Nuñez, N.; Vazquez, M.; Segura-Antunez, C.; González-Posadas, V.

2015-09-01

High-power (HP) UV-LEDs can replace UV lamps for real-time fluoro-sensing applications by allowing portable and autonomous systems. However, HP UV-LEDs are not a mature technology, and there are still open issues regarding their performance evolution over time. This paper presents a reliability study of 3 W UV-LEDs, with special focus on LED degradation for two working conditions: continuous and cycled (30 s ON and 30 s OFF). Accelerated life tests are developed to evaluate the influence of temperature and electrical working conditions in high-power LEDs degradation, being the predominant failure mechanism the degradation of the package. An analysis that includes dynamic thermal and optical HP UV-LED measurements has been performed. Static thermal and stress simulation analysis with the finite element method (FEM) identifies the causes of package degradation. Accelerated life test results prove that HP UV-LEDs working in cycled condition have a better performance than those working in continuous condition.

The use of administrative data is common practice in public health research. The present field note describes the Continuous Working Life Sample (CWLS) and its use in health research. The CWLS is built on records generated by all contacts with the social security system (work contracts, disability, etc.), plus tax data (monetary gains, income, etc.) and census data (level of education, country of birth, etc.), but does not allow individuals to be identified. The CWLS was started in 2004 with 4% (1.1 million persons) of the total population who were either contributors to or beneficiaries of the social security system. The information on the individuals in the CWLS is updated annually and lost individuals are replaced. This continuous design allows the construction of a cohort with information on working life and financial status and evaluation of their relationship with work disability. Future connection with clinical records would enable analysis of other health-related outcomes. Copyright © 2013 SESPAS. Published by Elsevier Espana. All rights reserved.

1981-08-01

This report on the CPA Questionnaire on Continuing Education represents the answers of a sample of 485 of the 1,360 certified psychiatrists belonging to the Association. A total of 72.6% of the sample lived in urban centres with populations greater than 200,000; 28.9% worked in solo practice, but only 7.4% worked in settings where no other psychiatrists were present. The amount of time spent in continuing education activities was found to vary inversely with the distance that had to be travelled to major educational centres. Nevertheless, there were no psychiatrists that did not partake in some continuing education activities. Ninety-three percent read journals, 99% went to meetings, and 96% used consultation with other psychiatrists; 99% stated that these activities were useful. The favourite methods were reading and consultation. Eighty percent of the sample spent more than 41 hours per month in continuing education activities. Sixty-five percent stated that they would like a voluntary credit award system instituted. It is concluded that Canadian psychiatrists do spend a great deal of time in continuing education activities and believe that this is of value to their professional work.

A discrete model for geometrically nonlinear transverse free constrained vibrations of beams with various end conditions

NASA Astrophysics Data System (ADS)

Rahmouni, A.; Beidouri, Z.; Benamar, R.

2013-09-01

The purpose of the present paper was the development of a physically discrete model for geometrically nonlinear free transverse constrained vibrations of beams, which may replace, if sufficient degrees of freedom are used, the previously developed continuous nonlinear beam constrained vibration models. The discrete model proposed is an N-Degrees of Freedom (N-dof) system made of N masses placed at the ends of solid bars connected by torsional springs, presenting the beam flexural rigidity. The large transverse displacements of the bar ends induce a variation in their lengths giving rise to axial forces modelled by longitudinal springs. The calculations made allowed application of the semi-analytical model developed previously for nonlinear structural vibration involving three tensors, namely the mass tensor mij, the linear rigidity tensor kij and the nonlinearity tensor bijkl. By application of Hamilton's principle and spectral analysis, the nonlinear vibration problem is reduced to a nonlinear algebraic system, examined for increasing numbers of dof. The results obtained by the physically discrete model showed a good agreement and a quick convergence to the equivalent continuous beam model, for various fixed boundary conditions, for both the linear frequencies and the nonlinear backbone curves, and also for the corresponding mode shapes. The model, validated here for the simply supported and clamped ends, may be used in further works to present the flexural linear and nonlinear constrained vibrations of beams with various types of discontinuities in the mass or in the elasticity distributions. The development of an adequate discrete model including the effect of the axial strains induced by large displacement amplitudes, which is predominant in geometrically nonlinear transverse constrained vibrations of beams [1]. The investigation of the results such a discrete model may lead to in the case of nonlinear free vibrations. The development of the analogy between the previously developed models of geometrically nonlinear vibrations of Euler-Bernoulli continuous beams, and multidof system models made of N masses placed at the end of elastic bars connected by linear spiral springs, presenting the beam flexural rigidity. The validation of the new model via the analysis of the convergence conditions of the nonlinear frequencies obtained by the N-dof system, when N increases, and those obtained in previous works using a continuous description of the beam. In addition to the above points, the models developed in the present work, may constitute, in our opinion, a good illustration, from the didactic point of view, of the origin of the geometrical nonlinearity induced by large transverse vibration amplitudes of constrained continuous beams, which may appear as a Pythagorean Theorem effect. The first step of the work presented here was the formulation of the problem of nonlinear vibrations of the discrete system shown in Fig. 1 in terms of the semi-analytical method, denoted as SAA, developed in the early 90's by Benamar and coauthors [3], and discussed for example in [6,7]. This method has been applied successfully to various types of geometrically nonlinear problems of structural dynamics [1-3,6-8,10-12] and the objective here was to use it in order to develop a flexible discrete nonlinear model which may be useful for presenting in further works geometrically nonlinear vibrations of real beams with discontinuities in the mass, the section, or the stiffness distributions. The purpose in the present work was restricted to developing and validating the model, via comparison of the obtained dependence of the resonance frequencies of such a system on the amplitude of vibration, with the results obtained previously by continuous beams nonlinear models. In the SAA method, the dynamic system under consideration is described by the mass matrix [M], the rigidity matrix [K], and the nonlinear rigidity matrix [B], which depends on the amplitude of vibration, and involves a fourth-order nonlinearity tensor bijkl. Details are given below, corresponding to the definition of the tensors mentioned above. The analogy between the classical continuous Euler-Bernoulli model of beams and the present discrete model is developed, leading to the expressions for the equivalent spiral and axial stiffness, in terms of the continuous beam geometrical and mechanical characteristics. Some numerical results are also given, showing the amplitude dependence of the frequencies on the amplitude of vibration, and compared to the backbone curves obtained previously by the continuous nonlinear classical beam theory, presented for example in [3,5,8,15-22]. A convergence study is performed by increasing the number of masses and bars, showing a good convergence to the theoretical values of continuous beams.

1999-01-01

The need for a continuous air monitor capable of quick and accurate measurements of airborne radioactivity in close proximity to the work environment during waste management, site restoration, and D&D operations led to the Los Alamos National Laboratory development of an environmental continuous air monitor (ECAM). Monitoring the hostile work environment of waste recovery, for example, presents unique challenges for detector design for detectors previously used for the clean room conditions of the typical plutonium laboratory. The environmental and atmospheric conditions (dust, high wind, etc.) influence aerosol particle penetration into the ECAM sampling head as well as the build-up of deposits on the ECAM filter.

Karoly, Paul; Ruehlman, Linda S.; Okun, Morris A.

2013-01-01

Background Although chronic pain is a source of work-related disability, relatively little research has addressed the psychological factors that differentiate individuals in chronic pain who leave the workforce from those who remain on the job despite their pain. Objective The present study examined a small set of attitudinal and coping-related factors as potential correlates of pain-related disability versus continued part- or full time employment over and above the role of well-known risk factors. Methods A large sample of adult men and women with chronic pain drawn from across the United States (N= 1293) by means of random digit dialing was subdivided into two groups: working (N = 859) and on disability (N = 434). Both groups were interviewed (by telephone) to complete a set of instruments (called the Profile of Chronic Pain: Extended Assessment [PCP: EA] Battery) measuring pain attitudes and coping methods. Results Logistic regression analysis revealed, as expected, that continued employment status was inversely related to pain severity and work status was positively related to higher education and being Hispanic. After controlling for severity and demographic factors, belief in a medical cure and catastrophizing tendencies were significant inverse predictors and task persistence was a positive predictor of continued employment. Conclusions Results revealed both demographic and attitudinal predictors of continued employment, and highlight the value of harnessing insights from the psychology of work engagement to better understand the processes underlying pain presenteeism. Interventions designed to keep persons with pain in the active work force should build upon and extend the present findings. PMID:24010682

Currently available, pneumatic-based medical devices are operated using closed-loop pulsatile or open continuous systems. Medical devices utilizing gases with a low atomic number in a continuous closed loop stream have not been documented to date. This work presents the construction of a portable helium circulation addressing the need for actuating a novel, pneumatically operated catheter pump. The design of its control system puts emphasis on the performance, safety and low running cost of the catheter pump. Static and dynamic characteristics of individual elements in the circulation are analyzed to ensure a proper operation of the system. The pneumatic circulation maximizes the working range of the drive unit inside the catheter pump while reducing the total size and noise production.Separate flow and pressure controllers position the turbine's working point into the stable region of the pressure creation element. A subsystem for rapid gas evacuation significantly decreases the duration of helium removal after a leak, reaching subatmospheric pressure in the intracorporeal catheter within several milliseconds. The system presented in the study offers an easy control of helium mass flow while ensuring stable behavior of its internal components.

CONTINUOUS-ENERGY MONTE CARLO METHODS FOR CALCULATING GENERALIZED RESPONSE SENSITIVITIES USING TSUNAMI-3D

Perfetti, Christopher M; Rearden, Bradley T

2014-01-01

This work introduces a new approach for calculating sensitivity coefficients for generalized neutronic responses to nuclear data uncertainties using continuous-energy Monte Carlo methods. The approach presented in this paper, known as the GEAR-MC method, allows for the calculation of generalized sensitivity coefficients for multiple responses in a single Monte Carlo calculation with no nuclear data perturbations or knowledge of nuclear covariance data. The theory behind the GEAR-MC method is presented here, and proof of principle is demonstrated by using the GEAR-MC method to calculate sensitivity coefficients for responses in several 3D, continuous-energy Monte Carlo applications.

Heralded processes on continuous-variable spaces as quantum maps

2014-12-04

Heralding processes, which only work when a measurement on a part of the system give the good result, are particularly interesting for continuous-variables. They permit non-Gaussian transformations that are necessary for several continuous-variable quantum information tasks. However if maps and quantum process tomography are commonly used to describe quantum transformations in discrete-variable space, they are much rarer in the continuous-variable domain. Also, no convenient tool for representing maps in a way more adapted to the particularities of continuous variables have yet been explored. In this paper we try to fill this gap by presenting such a tool.

2016-11-01

Patients on sick leave due to work-related stress often present with cognitive impairments. The aim of this prospective cohort study was to examine the long-term consequences of prolonged work-related stress in terms of cognitive functioning one year after initial professional care seeking. We tested a group of patients with work-related stress with a comprehensive neuropsychological test battery at two occasions, one year apart. At both time points, we compared the performance of patients with healthy controls matched pairwise on sex, age and length of education. This paper presents the results from the one-year follow-up. When adjusting for practice effects, patients improved on measures of prospective memory and processing speed. However, patients continued to perform worse than controls on all tests, though only half of the comparisons reached statistical significance. The effect sizes of the differences between the two groups at one-year follow-up were small to medium. In conclusion, former patients with prolonged work-related stress improved, but they continued to perform worse than controls after one year. In the acute phase, the largest impairments were related to executive function and mental speed but at follow-up memory impairments also became apparent.

A nursing career can last for more than 40 years, during which continuing professional development is essential. Nurses participate in a variety of learning activities that correspond with their developmental motives. Lifespan psychology shows that work-related motives change with age, leading to the expectation that motives for continuing professional development also change. Nevertheless, little is known about nurses' continuing professional development strategies in different age groups. To explore continuing professional development strategies among younger, middle-aged, and older nurses. A qualitative study using semi-structured interviews, from a biographical perspective. Data were analysed using a vertical process aimed at creating individual learning biographies, and a horizontal process directed at discovering differences and similarities between age groups. Twenty-one nurses in three age groups from general and academic hospitals in the Netherlands. In all age groups, daily work was an important trigger for professional development on the ward. Performing extra or new tasks appeared to be an additional trigger for undertaking learning activities external to the ward. Learning experiences in nurses' private lives also contributed to their continuing professional development. Besides these similarities, the data revealed differences in career stages and private lives, which appeared to be related to differences in continuing professional development strategy; 'gaining experience and building a career' held particularly true among younger nurses, 'work-life balance' and 'keeping work interesting and varied' to middle-aged nurses, and 'consistency at work' to older nurses. Professional development strategies can aim at performing daily patient care, extra tasks and other roles. Age differences in these strategies appear to relate to tenure, perspectives on the future, and situations at home. These insights could help hospitals to orientate continuing professional development approaches toward the needs of all age groups. This should be particularly relevant in the face of present demographic changes in the nursing workforce. Copyright © 2015 Elsevier Ltd. All rights reserved.

Criteria for genuine N -partite continuous-variable entanglement and Einstein-Podolsky-Rosen steering

NASA Astrophysics Data System (ADS)

Teh, R. Y.; Reid, M. D.

2014-12-01

Following previous work, we distinguish between genuine N -partite entanglement and full N -partite inseparability. Accordingly, we derive criteria to detect genuine multipartite entanglement using continuous-variable (position and momentum) measurements. Our criteria are similar but different to those based on the van Loock-Furusawa inequalities, which detect full N -partite inseparability. We explain how the criteria can be used to detect the genuine N -partite entanglement of continuous variable states generated from squeezed and vacuum state inputs, including the continuous-variable Greenberger-Horne-Zeilinger state, with explicit predictions for up to N =9 . This makes our work accessible to experiment. For N =3 , we also present criteria for tripartite Einstein-Podolsky-Rosen (EPR) steering. These criteria provide a means to demonstrate a genuine three-party EPR paradox, in which any single party is steerable by the remaining two parties.

Universal Quantum Computing with Arbitrary Continuous-Variable Encoding.

PubMed

Lau, Hoi-Kwan; Plenio, Martin B

2016-09-02

Implementing a qubit quantum computer in continuous-variable systems conventionally requires the engineering of specific interactions according to the encoding basis states. In this work, we present a unified formalism to conduct universal quantum computation with a fixed set of operations but arbitrary encoding. By storing a qubit in the parity of two or four qumodes, all computing processes can be implemented by basis state preparations, continuous-variable exponential-swap operations, and swap tests. Our formalism inherits the advantages that the quantum information is decoupled from collective noise, and logical qubits with different encodings can be brought to interact without decoding. We also propose a possible implementation of the required operations by using interactions that are available in a variety of continuous-variable systems. Our work separates the "hardware" problem of engineering quantum-computing-universal interactions, from the "software" problem of designing encodings for specific purposes. The development of quantum computer architecture could hence be simplified.

The aim of the present study was to analyse the impact of organisational characteristics on the turnover intention of care workers working at nursing homes in Korea. Study participants included 504 care workers working at 14 nursing homes in Korea. The variables measured were: high-performance work practices, consisting of five subfactors (official training, employment stability, autonomy, employee participation and group-based payment); organisational commitment, consisting of three subfactors (affective, normative and continuance commitment); organisational support; and turnover intention. The inter-relationship between high-performance work practices, organisational support, organisational commitment and turnover intention and the fit of the hypothetical model were analysed using structural equation modelling. According to our analysis, high-performance work practices not only had a direct effect on turnover intention, but also an indirect effect by mediating organisational support and commitment. The factor having the largest direct influence on turnover intention was organisational commitment. The results of the present study suggest that to improve health conditions for frail elderly patients at nursing homes, as well as the efficiency of nursing homes through the continuance of nursing service and enhancement of quality of service, long-term care facilities should reduce the turnover intention of care workers by increasing their organisational commitment by actively implementing high-performance work practices.

Scientific and educational poster presentations in national and international meetings are one of the most effective means of scientific communication. Poster presentations are of particular importance in a mainly visual speciality like radiology, and also play a significant role in continuing medical education in our specialty. However, poster should be no more than an intermediate step on the way to publish our work in a scientific journal. The publication rates of posters prented in courses and conferences is very low in our country. Therefore, we must continue to progress in training in scientific publication, with efforts such as this supplement. This article review how to create an effective poster presentation.

2017-01-01

This manuscript presents the results of a multi-lateral international activity intended to understand how to execute a cycle stress test as specified in a chosen standard (GTR, SAE, ISO, EIHP...). The purpose of this work was to establish a harmonized test method protocol to ensure that the same results would be achieved regardless of the testing facility. It was found that accurate temperature measurement of the working fluid is necessary to ensure the test conditions remain within the tolerances specified. Continuous operation is possible with adequate cooling of the working fluid but this becomes more demanding if the cycle frequency increases. Recommendations for future test system design and operation are presented.

The intention to continue nursing: work variables affecting three nurse generations in Australia.

Shacklock, Kate; Brunetto, Yvonne

2012-01-01

The aims of the study were to examine how seven variables impacted upon the intention of hospital nurses to continue working as nurses and to investigate whether there are generational differences in these impacts. There is a critical shortage of trained nurses working as nurses in Australia, as in many other Organisation for Economic Co-operation and Development member countries. The retention of nurses has been examined from the traditional management perspectives; however, this paper presents a different approach (Meaning of Working theory). A self-report survey of 900 nurses employed across four states of Australia was completed in 2008. The sample was hospital nurses in Australia from three generational cohorts - Baby Boomers (born in Australia between 1946 and 1964), Generation X (1965-1979) and Generation Y (1980-2000). Six variables were found to influence the combined nurses' intentions to continue working as nurses: work-family conflict, perceptions of autonomy, attachment to work, importance of working to the individual, supervisor-subordinate relationship and interpersonal relationships at work. There were differences in the variables affecting the three generations, but attachment to work was the only common variable across all generations, affecting GenYs the strongest. The shortage of nurses is conceptualized differently in this paper to assist in finding solutions. However, the results varied for the three generations, suggesting the need to tailor different retention strategies to each age group. Implications for management and policy planning are discussed. © 2011 Blackwell Publishing Ltd.

In Japan, although the number of females who continue to work after marriage has recently increased, the proportion of those working while parenting their infants is still not clearly increasing, indicating that it is still difficult for them to continue working after delivery. The present study aimed to clarify factors influencing females' continuation of work, using data obtained by continuously following up the same subjects and focusing on occupation changes, family environments, and the type of employment after pregnancy or delivery. Based on the results of the questionnaire survey, which was conducted involving 164 participants at 4 universities, as part of the Japan Environment and Children's Pilot Study (JECS Pilot Study) led by the Ministry of Environment and the National Institute for Environmental Studies, the occupational status was compared between the detection of pregnancy (weeks 0 to 7) and 1 year after delivery. compared with changed their occupations significantly more frequently (OR = 5.07, 95% CI = 2.57-10.01, P < 0.001). Furthermore, on examining in detail, occupation changes were particularly marked among (OR = 12.48, 95% CI = 4.43-35.15, P < 0.001). This tendency was especially shown among  > (OR = 10.36, 95% CI = 1.59-67.38, P = 0.014) and <  > (OR = 15.15, 95% CI = 2.55-90.17, P = 0.003). Analysis revealed that the type of employment, rather than the category of occupation, was associated with the continuation of work after pregnancy or delivery more closely, as compared with continued to work less frequently. Furthermore, on comparison of the category of occupation among ,  > and <  > were shown to be more likely to continue to be engaged in the same occupation after pregnancy or delivery. These differences may be related to availability of the child-care leave program and other support resources, therefore, it may be important to establish social systems that enable all females, to use these support resources if they wish, and actively work, while delivering and parenting their children.

Persistence motives in irrational decisions to complete a boring task.

PubMed

Halkjelsvik, Torleif; Rise, Jostein

2015-01-01

We explored a novel task paradigm where participants from the online work marketplace Amazon Mechanical Turk were given the choice to quit or continue an unfinished boring task for identical economic rewards. In Studies 1a and 1b, about half the participants chose to continue (corresponding to an average of 55 and 35 cents in foregone earnings). Participants' self-reported reasons for continuing involved various types of persistence motives, reflecting a desire to persist or complete per se. Studies 2, 3a, 3b, and 3c ruled out the possibility that people continued because they enjoyed the task or believed there were additional rewards for continuing. Study 4 showed that the choice to quit/continue was associated with the manner in which the choice was presented (persistence test vs. decision-making test) and individual differences in dispositional persistence motives. The present data indicate that motivational forces independent of the focal reward may affect intertemporal decisions. © 2014 by the Society for Personality and Social Psychology, Inc.

Quality in rehabilitation after a working age person has sustained a fracture: partnership contributes to continuity.

PubMed

Lindahl, Marianne; Hvalsoe, Berit; Poulsen, Jeppe Rosengaard; Langberg, Henning

2013-01-01

Research in quality of rehabilitation has mostly concerned patients with chronic diseases, but the aim of the present study was to investigate what constitutes good quality in rehabilitation after a person has sustained a fracture at working age, from both patients' and therapists' perspectives. Seven patients with bone fracture, aged 32-60 years, and 23 occupational therapists and physiotherapists from hospitals, municipalities and private practices in Denmark. Qualitative study with in-depth semi-structured interviews. Data were analyzed according to grounded theory method. Partnership was a central theme that was constituted by continuity of rehabilitation and therapists' use of a patient-centred approach. Patients' experiences of continuity of rehabilitation was supported, not only by organizational factors, but depended also on values constituting the patient-centred approach. Therapists used their professional network to refine the transition process from hospital into the community, but there was no co-operation between departments in the municipalities about patients' return to work. The study suggests that patients with acute injuries need partnership, respect, and understanding through the rehabilitation course. Personal relations were important for continuity of rehabilitation (i.e. that organizational quality depended more on therapists' efforts to promote continuity for the patient than organizational tools).

Space Flight Cable Model Development

NASA Technical Reports Server (NTRS)

Spak, Kaitlin

2013-01-01

This work concentrates the modeling efforts presented in last year's VSGC conference paper, "Model Development for Cable-Harnessed Beams." The focus is narrowed to modeling of space-flight cables only, as a reliable damped cable model is not yet readily available and is necessary to continue modeling cable-harnessed space structures. New experimental data is presented, eliminating the low-frequency noise that plagued the first year's efforts. The distributed transfer function method is applied to a single section of space flight cable for Euler-Bernoulli and shear beams. The work presented here will be developed into a damped cable model that can be incorporated into an interconnected beam-cable system. The overall goal of this work is to accurately predict natural frequencies and modal damping ratios for cabled space structures.

This report summarizes academic research which has resulted in an increased appreciation for multidisciplinary efforts among our students, colleagues and administrators. It has also generated a number of research ideas that emerged from the interaction between disciplines. Overall, 17 undergraduate students and 16 graduate students benefited directly from the NASA grant: an additional 11 graduate students were impacted and participated without financial support from NASA. The work resulted in 16 theses (with 7 to be completed in the near future), 67 papers or reports mostly published in 8 journals and/or presented at various conferences (a total of 83 papers, presentations and reports published based on NASA inspired or supported work). In addition, the faculty and students presented related work at many meetings, and continuing work has been proposed to NSF, the Army, Industry and other state and federal institutions to continue efforts in the direction of multidisciplinary and recently multi-objective design and analysis. The specific problem addressed is component packing which was solved as a multi-objective problem using iterative genetic algorithms and decomposition. Further testing and refinement of the methodology developed is presently under investigation. Teaming issues research and classes resulted in the publication of a web site, (http://design.eng.clemson.edu/psych4991) which provides pointers and techniques to interested parties. Specific advantages of using iterative genetic algorithms, hurdles faced and resolved, and institutional difficulties associated with multi-discipline teaming are described in some detail.

Characteristics of the work environment related to older employees' willingness to continue working: intrinsic motivation as a mediator.

PubMed

van den Berg, Peter T

2011-08-01

The relationships between older employees' willingness to continue working and characteristics of the work environment for older workers were investigated, as well as a possible mediation by intrinsic motivation. 103 employees ages 50 to 65 years, from various sectors of the Dutch labor market, completed questionnaires that measured willingness to continue working, intrinsic motivation, organizational stimulation, work variety, work challenge, and job autonomy. Hierarchical regression analyses showed organizational stimulation, as well as the various job characteristics, were positively related to employees' willingness to continue working. Moreover, intrinsic motivation fully mediated the relationship of work variety with willingness to continue working and partially mediated the relationships of organizational stimulation, work challenge, and job autonomy with willingness to continue working. It was concluded that organizations can encourage older workers to work until age 65 and beyond by shifting their focus from extrinsic to intrinsic rewards.

This paper proposes a Markov decision process (MDP) model that features both discrete and continuous state variables. We extend previous work by Boyan and Littman on the mono-dimensional time-dependent MDP to multiple dimensions. We present the principle of lazy discretization, and piecewise constant and linear approximations of the model. Having to deal with several continuous dimensions raises several new problems that require new solutions. In the (piecewise) linear case, we use techniques from partially- observable MDPs (POMDPS) to represent value functions as sets of linear functions attached to different partitions of the state space.

Redelheim, P S; Pomeroy, L H; Batalden, P

1994-01-01

In the first part of this article, published in the November/December 1993 issue of Behavioral Healthcare Tomorrow, the authors presented a framework for understanding the process of continuous quality improvement in the behavioral healthcare setting. Four elements of continual improvement were identified: underlying knowledge, policy for leadership, tools and methods, and daily work applications. They showed how traditional professional knowledge of one's subject, discipline and values must be augmented by improvement knowledge--which quality improvement guru W. Edwards Deming calls "the system of profound knowledge." In Part II, they focus on the second element of continual improvement, the importance of organizational leadership.

An automated technique for manufacturing thermoplastic stringers in continuous length

NASA Astrophysics Data System (ADS)

Pantelakis, Sp.; Baxevani, E.; Spelz, U.

In the present work an automated Continuous Compression Moulding Technique for the manufacture of stringers in continuous length is presented. The method combines pultrusion and hot-pressing. The technique is utilized for the production of L-shape stringers which are widely applied in aerospace constructions. The investigation was carried out on carbon reinforced PEEK (C/PEEK), as well as, for comparison, on the thermoplastic composites carbon reinforced polyethersulfon (C/PES), glass and carbon reinforced polyphenylene-sulfide (G/PPS, C/PPS) and Kevlar reinforced Polyamide 6 (K/PA 6). For the materials investigated the optimized process parameters for manufacturing the L-shape stringers were derived experimentally. To achieve this goal, the quality of the produced parts was controlled by using non-destructive testing techniques. Parts providing satisfactory quality were also tested destructively to measure their mechanical properties. The investigation results have shown the suitability of the technique to produce continuous length stringers.

Droplet microfluidics with a nanoemulsion continuous phase.

PubMed

Gu, Tonghan; Yeap, Eunice W Q; Somasundar, Ambika; Chen, Ran; Hatton, T Alan; Khan, Saif A

2016-07-05

We present the first study of a novel, generalizable method that uses a water-in-oil nanoemulsion as the continuous phase to generate uniform aqueous micro-droplets in a capillary-based microfluidic system. We first study the droplet generation mechanism in this system and compare it to the more conventional case where a simple oil/solvent (with surfactant) is used as the continuous phase. Next, we present two versatile methods - adding demulsifying chemicals and heat treatment - to allow active online chemical interaction between the continuous and dispersed phases. These methods allow each generated micro-droplet to act as a well-mixed micro-reactor with walls that are 'permeable' to the nanoemulsion droplets and their contents. Finally, we demonstrate an application of this system in the fabrication of uniform hydrogel (alginate) micro-beads with control over particle properties such as size and swelling. Our work expands the toolbox of droplet-based microfluidics, enabling new opportunities and applications involving active colloidal continuous phases carrying chemical payloads, both in advanced materials synthesis and droplet-based screening and diagnostic methods.

Fine motor movements while drawing during the encoding phase of a serial verbal recall task reduce working memory performance.

PubMed

Tindle, Richard; Longstaff, Mitchell G

2016-02-01

The time-based resource-sharing (TBRS) model of working memory indicates that secondary tasks that capture attention for relatively long periods can result in the interference of working memory processing and maintenance. The current study investigates if discrete and continuous movements have differing effects on a concurrent, verbal serial recall task. In the listening condition, participants were asked to recall spoken words presented in lists of six. In the drawing conditions, participants performed the same task while producing discrete (star) or continuous (circle) movements. As hypothesised, participants recalled more words overall in the listening condition compared to the combined drawing conditions. The prediction that the continuous movement condition would reduce recall compared to listening was also supported. Fine-grained analysis at each serial position revealed significantly more words were recalled at mid serial positions in the listening condition, with worst recall for the continuous condition at position 5 compared to the listening and discrete conditions. Kinematic analysis showed that participants increased the size and speed of the continuous movements resulting in a similar duration and number of strokes for each condition. The duration of brief pauses in the discrete condition was associated with the number of words recalled. The results indicate that fine motor movements reduced working memory performance; however, it was not merely performing a movement but the type of the movement that determined how resources were diverted. In the context of the TBRS, continuous movements could be capturing attention for longer periods relative to discrete movements, reducing verbal serial recall. Copyright © 2016 Elsevier B.V.

Participatory design in lean production: which contribution from employees? For what end?

PubMed

Perez Toralla, M S; Falzon, P; Morais, A

2012-01-01

The proponents of lean production have pointed to the positive effects of the work organization on employees in terms of autonomy, enhanced skills and empowerment mainly by their participation into the continuous improvement of work process. But studies that have examined this issue suggest that the increase in autonomy is not sufficient to compensate for increases work intensity. Participatory design has grown extensively in manufacturing since the 1980's under the impulsion of the Scandinavian socio-technical system approach and it's central in the model of lean production performance. Its main objectives are to improve quality, increase productivity and safety through employee's participation to the reduction of non-value added activities, such as defined by lean production. In the line of the studies on participatory design and continuous improvement the present study examines the functioning of work groups, based on the kaizen model, the aim of which was to improve the proportion of "value-added activities" and working conditions, essentially physical constraints. The main results are consistent with the literature and show that accelerated forms of re-conception activities give employees limited room for maneuver to elaborate solutions based on the analysis of the real activity. This study is part of a broader initiative that goes in the direction of continuous improvement of the design process itself so that it integrates the real constraints of work and propose changes bases on work as it actually takes place, beyond pre-established performance goals bases on the reduction of "non added value activities".

The juxtaposition of ageing and nursing: the challenges and enablers of continuing to work in the latter stages of a nursing career.

To identify why some nurses cope well with continuing to work as they age and others struggle. There is a need to understand better the challenges older nurses face and how they manage them. Secondary analysis of existing data. Data collected in two separate studies were analysed. The first study (2012) was an online, anonymous survey that collected free text (qualitative) and categorical data (n = 3273, 57·6% response rate). The second (2014) was an explorative, descriptive study that collected data through focus groups and interviews (n = 46). Qualitative data from both studies were analysed using David Thomas' () general inductive approach. Research Ethics Committee approval was gained for the 2012 and 2014 studies. Data were categorised in two themes: the challenges of ageing and nursing; and factors that enable nurses to continue to practice. Physical challenges, fatigue, guilt, ageism and demands to complete continuing education were considered challenges. Maintaining personal fitness, self care, flexible working and a strong belief in their ability to contribute to the profession were present in older nurses who continued to practice. While older nurses face growing physical and cognitive challenges as they age, they demonstrate strong resilience in the face of these challenges. It is recommended nurses seek support from their workplaces early to address challenges. Organisations must address ageism in the workplace and provide practical interventions such as supporting changes to work hours, shifting nurses to less physical roles and providing career planning to support resilience in older workers. © 2016 John Wiley & Sons Ltd.

Why some colors appear more memorable than others: A model combining categories and particulars in color working memory.

PubMed

Bae, Gi-Yeul; Olkkonen, Maria; Allred, Sarah R; Flombaum, Jonathan I

2015-08-01

Categorization with basic color terms is an intuitive and universal aspect of color perception. Yet research on visual working memory capacity has largely assumed that only continuous estimates within color space are relevant to memory. As a result, the influence of color categories on working memory remains unknown. We propose a dual content model of color representation in which color matches to objects that are either present (perception) or absent (memory) integrate category representations along with estimates of specific values on a continuous scale ("particulars"). We develop and test the model through 4 experiments. In a first experiment pair, participants reproduce a color target, both with and without a delay, using a recently influential estimation paradigm. In a second experiment pair, we use standard methods in color perception to identify boundary and focal colors in the stimulus set. The main results are that responses drawn from working memory are significantly biased away from category boundaries and toward category centers. Importantly, the same pattern of results is present without a memory delay. The proposed dual content model parsimoniously explains these results, and it should replace prevailing single content models in studies of visual working memory. More broadly, the model and the results demonstrate how the main consequence of visual working memory maintenance is the amplification of category related biases and stimulus-specific variability that originate in perception.

Dental manpower planning in India: current scenario and future projections for the year 2020.

PubMed

Vundavalli, Sudhakar

2014-04-01

Dental manpower issues in India are discussed in this article which consists of both qualitative and quantitative research. The output of qualified dentists has increased substantially over last decade and at present there are over 117,825 dentists working in India. Although India has a dentist to population ratio of 1:10,271, the newly graduating dentists find it difficult to survive in the private sector. At present less than approximately 5% graduated dentists are working in the Government sector. If the present situation continues there will be more than one lakh dentists over supply by the year 2020. Continuation of the current situation will lead to wastage of highly trained dental manpower and create a threat to the professional integrity of the dentists. This research highlights the fact that there is an urgent need for an organised national human resource planning system to control the supply and demand of dental manpower, to ensure a uniform distribution of manpower and to give future directions to policy makers. © 2013 FDI World Dental Federation.

How Visual Management for Continuous Improvement Might Guide and Affect Hospital Staff: A Case Study.

PubMed

2015-01-01

Visual management (VM) tools such as whiteboards, often employed in Lean thinking applications, are intended to be helpful in improving work processes in different industries including health care. It remains unclear, however, how VM is actually applied in health care Lean interventions and how it might influence the clinical staff. We therefore examined how Lean-inspired VM using whiteboards for continuous improvement efforts related to the hospital staff's work and collaboration. Within a case study design, we combined semistructured interviews, nonparticipant observations, and photography on 2 cardiology wards. The fate of VM differed between the 2 wards; in one, it was well received by the staff and enhanced continuous improvement efforts, whereas in the other ward, it was not perceived to fit in the work flow or to make enough sense in order to be sustained. Visual management may enable the staff and managers to allow communication across time and facilitate teamwork by enabling the inclusion of team members who are not present simultaneously; however, its adoption and value seem contingent on finding a good fit with the local context. A combination of continuous improvement and VM may be helpful in keeping the staff engaged in the change process in the long run.

Effect of the application of an electric field on the performance of a two-phase loop device: preliminary results

NASA Astrophysics Data System (ADS)

Creatini, F.; Di Marco, P.; Filippeschi, S.; Fioriti, D.; Mameli, M.

2015-11-01

In the last decade, the continuous development of electronics has pointed out the need for a change in mind with regard to thermal management. In the present scenario, Pulsating Heat Pipes (PHPs) are novel promising two-phase passive heat transport devices that seem to meet all present and future thermal requirements. Nevertheless, PHPs governing phenomena are quite unique and not completely understood. In particular, single closed loop PHPs manifest several drawbacks, mostly related to the reduction of device thermal performance and reliability, i.e. the occurrence of multiple operational quasi-steady states. The present research work proposes the application of an electric field as a technique to promote the circulation of the working fluid in a preferential direction and stabilize the device operation. The tested single closed loop PHP is made of a copper tube with an inner tube diameter equal to 2.00 mm and filled with pure ethanol (60% filling ratio). The electric field is generated by a couple of wire-shaped electrodes powered with DC voltage up to 20 kV and laid parallel to the longitudinal axis of the glass tube constituting the adiabatic section. Although the electric field intensity in the working fluid region is weakened both by the polarization phenomenon of the working fluid and by the interposition of the glass tube, the experimental results highlight the influence of the electric field on the device thermal performance and encourage the continuation of the research in this direction.

This article establishes the importance of "context", a concept that underpins the academic contributions that John Falk and Lynn Dierking have made in building the field of informal/free-choice learning in science education. I consider, in turn, the individual contributions made by each of them prior to their seminal co-authored work, entitled The Museum Experience. I then document their joint contributions to the field, pointing out that although their interests and skills overlap in complementary ways to produce their jointly authored works, both have continued to make their individual contributions; Falk in his work on identity and impact, and Dierking in her work on community, youth, family and equity. Finally I come to the present, describing how they each continue their research and publication in lifelong, life-wide, and life-deep learning, with a particular focus on free-choice learning and the role it can play in addressing critical issues in the world.

A follow-up working conference was held at Lewis Research Center (now Glenn Research Center) on September 23-25, 1997, to continue discussing issues related to the development of Web-based education materials for the K-14 community. The conference continued the collaboration among the NASA aerospace technology Centers (Ames, Dryden, Langley, and Lewis [now Glenn]), NASA Headquarters, the University of Idaho and the Pennsylvania State University. The conference consisted of presentations by the Aeronautics Cooperative Agreement teams, and working sessions that addressed issues related to the conference theme, responding to the K-14 customers needs. The group identified the most significant issues by consensus. The issues addressed were: classroom access, World Wide Web resources, teacher training, different teaching and learning styles, interactivity, and education standards. The working sessions produced observations and recommendations in each of these areas in order to work toward the goal of making NASA sponsored Web-based educational resources useful to teachers and students.

Declining sleep quality among nurses: a population-based four-year longitudinal study on the transition from nursing education to working life.

PubMed

Hasson, Dan; Gustavsson, Petter

2010-12-08

Several studies have established impaired sleep is a common problem among nurses. Overworked, fatigued and stressed nurses are at a higher risk of making mistakes that threaten patient safety as well as their own health. The aim of the present study was to longitudinally monitor the development of sleep quality in nurses, starting from the last semester at the university, with three subsequent annual follow-ups once the nurses had entered working life. Nationwide, longitudinal questionnaire study of nursing students and newly qualified nurses in Sweden. The results imply a continuous decline in sleep quality among nurses during the three years of follow-up, starting from their last semester of nursing education and continuing for three years into their working life. The most pronounced short-term decline in sleep quality seems to occur in the transition between student life and working life. This finding is important since it may affect the quality of care and the health of nurses negatively.

In Japan, working environment measurement is prescribed in the designated workplaces using hazardous materials. Measurements should be carried out periodically and countermeasures are performed depending on the results. By introducing such a system, working environments have remarkably improved. However, in the designated workplaces, measurements should be continued even in work environments found safe. On the other hand, measurement need not be obliged for non-designated workplaces even if hazardous materials are utilized.In the United States of America and many European countries, work environment management and work management are carried out by measuring personal exposure concentrations. In Japan, the Ministry of Health, Labour and Welfare is now discussing the introduction of personal exposure monitoring. However, many problems exist to prevent the simple introduction of American and European methods. This paper describes the brief history, present state and problems of work environment control in Japan, comparing with the systems of American and European countries.

2015-01-01

This paper examines the role of work in Charcot's clinical teaching focusing on cases of male hysteria in The Tuesday's Lessons from 1887 to 1889. Today, we read the work of Charcot in a retrospective way as having ended in a failure: He would have missed the discovery of the sexual unconscious. From the perspective of psychodynamics of work, it appears an alternative way which was present in Charcot, though unfinished, opening on a possible development of a relationship between psychic and body. The role of work in traumatic hysteria has been forgotten by Freud's posterity and this obliteration continues today.

Using the Rasch Model to Measure the Extent to which Students Work Conceptually with Mathematics.

Kaspersen, Eivind

2015-01-01

Differences between working conceptually and procedurally with mathematics are well documented. In short, working procedurally can be characterized as learning and applying rules without reason. Working conceptually, in contrast, means creating and applying a web of knowledge. To continue this line of research, an instrument that is able to measure the level of conceptual work, and that is based on the basic requirements of measurement, is desireable. As such, this paper presents a Rasch calibrated instrument that measures the extent to which students work conceptually with mathematics. From a sample of 133 student teachers and 185 Civil Engineering students, 20 items are concluded as being productive for measurement.

Enabling new graduate midwives to work in midwifery continuity of care models: A conceptual model for implementation.

PubMed

Cummins, Allison M; Catling, Christine; Homer, Caroline S E

2017-12-04

High-level evidence demonstrates midwifery continuity of care is beneficial for women and babies. Women have limited access to midwifery continuity of care models in Australia. One of the factors limiting women's access is recruiting enough midwives to work in continuity. Our research found that newly graduated midwives felt well prepared to work in midwifery led continuity of care models, were well supported to work in the models and the main driver to employing them was a need to staff the models. However limited opportunities exist for new graduate midwives to work in midwifery continuity of care. The aim of this paper therefore is to describe a conceptual model developed to enable new graduate midwives to work in midwifery continuity of care models. The findings from a qualitative study were synthesised with the existing literature to develop a conceptual model that enables new graduate midwives to work in midwifery continuity of care. The model contains the essential elements to enable new graduate midwives to work in midwifery continuity of care models. Each of the essential elements discussed are to assist midwifery managers, educators and new graduates to facilitate the organisational changes required to accommodate new graduates. The conceptual model is useful to show maternity services how to enable new graduate midwives to work in midwifery continuity of care models. Copyright © 2017 Australian College of Midwives.

Preferred strategies for workforce development: feedback from aged care workers.

PubMed

Choy, Sarojni; Henderson, Amanda

2016-11-01

Objective The aim of the present study was to investigate how aged care workers prefer to learn and be supported in continuing education and training activities. Methods Fifty-one workers in aged care facilities from metropolitan and rural settings across two states of Australia participated in a survey and interviews. Survey responses were analysed for frequencies and interview data provided explanations to the survey findings. Results The three most common ways workers were currently learning and prefer to continue to learn are: (1) everyday learning through work individually; (2) everyday learning through work individually assisted by other workers; and (3) everyday learning plus group training courses at work from the employer. The three most common types of provisions that supported workers in their learning were: (1) working and sharing with another person on the job; (2) direct teaching in a group (e.g. a trainer in a classroom at work); and (3) direct teaching by a workplace expert. Conclusions A wholly practice-based continuing education and training model is best suited for aged care workers. Two variations of this model could be considered: (1) a wholly practice-based model for individual learning; and (2) a wholly practice-based model with guidance from coworkers or other experts. Although the model is preferred by workers and convenient for employers, it needs to be well resourced. What is known about the topic? Learning needs for aged care workers are increasing significantly because of an aging population that demands more care workers. Workforce development is largely 'episodic', based on organisational requirements rather than systematic life-long learning. This study is part of a larger 3-year Australian research to investigate models of continuing education training. What does this paper add? Based on an analysis of survey and interview data from 51 workers, the present study suggests effective models of workforce development for aged care workers. What are the implications for practitioners? The effectiveness of the suggested models necessitates a culture where aged care workers' advancement in the workplace is valued and supported. Those responsible for the development of these workers need to be adequately prepared for mentoring and coaching in the workplace.

Despite a recent increase in the number of adults who work past traditional retirement age, existing theories of vocational behavior have not yet received adequate empirical support. In a large sample of adults age 60–87, we evaluated the relationship between theorized predictors of work satisfaction proposed by Social Cognitive Career Theory (SCCT), work satisfaction as a predictor of continued work, as proposed by the Theory of Work adjustment (TWA), as well as the influence of reported experiences of discrimination on these relationships. While the results supported most of the predicted relationships, the effects of discrimination were stronger than the variables proposed by either SCCT or TWA for the present sample. PMID:26101456

Application of Pulse Spark Discharges for Scale Prevention and Continuous Filtration Methods in Coal-Fired Power Plant

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cho, Young; Fridman, Alexander

2012-06-30

The overall objective of the present work was to develop a new scale-prevention technology by continuously precipitating and removing dissolved mineral ions (such as calcium and magnesium) in cooling water while the COC could be doubled from the present standard value of 3.5. The hypothesis of the present study was that if we could successfully precipitate and remove the excess calcium ions in cooling water, we could prevent condenser-tube fouling and at the same time double the COC. The approach in the study was to utilize pulse spark discharges directly in water to precipitate dissolved mineral ions in recirculating coolingmore » water into relatively large suspended particles, which could be removed by a self-cleaning filter. The present study began with a basic scientific research to better understand the mechanism of pulse spark discharges in water and conducted a series of validation experiments using hard water in a laboratory cooling tower. Task 1 of the present work was to demonstrate if the spark discharge could precipitate the mineral ions in water. Task 2 was to demonstrate if the selfcleaning filter could continuously remove these precipitated calcium particles such that the blowdown could be eliminated or significantly reduced. Task 3 was to demonstrate if the scale could be prevented or minimized at condenser tubes with a COC of 8 or (almost) zero blowdown. In Task 1, we successfully completed the validation study that confirmed the precipitation of dissolved calcium ions in cooling water with the supporting data of calcium hardness over time as measured by a calcium ion probe. In Task 2, we confirmed through experimental tests that the self-cleaning filter could continuously remove precipitated calcium particles in a simulated laboratory cooling tower such that the blowdown could be eliminated or significantly reduced. In addition, chemical water analysis data were obtained which were used to confirm the COC calculation. In Task 3, we conducted a series of heat transfer fouling tests using a condenser heat exchanger in the laboratory cooling tower, from which we confirmed that the plasma water treatment technology could prevent or significantly mitigate mineral foulings in condenser tubes when compared with the no-treatment case. With the completion of the present work, a cooling water treatment technology using pulse spark discharges is currently ready for field-validation tests. The plasma water treatment technology is a true mechanical water softener with almost no maintenance, which continuously converts hard water to soft water spending a relatively small amount of energy. Such a mechanical water softener could find wide-spread applications to solve hard water problems both in industry and at home.« less

Sherman, Aaron

2010-01-01

This slide presentation reviews the results of a study on the use of wireless instrumentation and sensors on future launch vehicles. The use of wireless technologies would if feasible would allow for fewer wires, and allow for more flexibility. However, it was generally concluded that wireless solutions are not currently ready to replace wired technologies for launch vehicles. The recommendations of the study were to continue to use wired sensors as the primary choice for vehicle instrumentation, and to continue to assess needs and use wireless instrumentation where appropriate. The future work includes support efforts for wireless technologies, and continue to monitor the development of wireless solutions.

Continuity equation for probability as a requirement of inference over paths

NASA Astrophysics Data System (ADS)

González, Diego; Díaz, Daniela; Davis, Sergio

2016-09-01

Local conservation of probability, expressed as the continuity equation, is a central feature of non-equilibrium Statistical Mechanics. In the existing literature, the continuity equation is always motivated by heuristic arguments with no derivation from first principles. In this work we show that the continuity equation is a logical consequence of the laws of probability and the application of the formalism of inference over paths for dynamical systems. That is, the simple postulate that a system moves continuously through time following paths implies the continuity equation. The translation between the language of dynamical paths to the usual representation in terms of probability densities of states is performed by means of an identity derived from Bayes' theorem. The formalism presented here is valid independently of the nature of the system studied: it is applicable to physical systems and also to more abstract dynamics such as financial indicators, population dynamics in ecology among others.

Working memory costs of task switching.

PubMed

Liefooghe, Baptist; Barrouillet, Pierre; Vandierendonck, André; Camos, Valérie

2008-05-01

Although many accounts of task switching emphasize the importance of working memory as a substantial source of the switch cost, there is a lack of evidence demonstrating that task switching actually places additional demands on working memory. The present study addressed this issue by implementing task switching in continuous complex span tasks with strictly controlled time parameters. A series of 4 experiments demonstrate that recall performance decreased as a function of the number of task switches and that the concurrent load of item maintenance had no influence on task switching. These results indicate that task switching induces a cost on working memory functioning. Implications for theories of task switching, working memory, and resource sharing are addressed.

Social Work Intervention Research With Adult Cancer Patients: A Literature Review and Reflection on Knowledge-Building for Practice.

PubMed

Pockett, Rosalie; Dzidowska, Monika; Hobbs, Kim

2015-01-01

The results of a literature review of social work intervention research with adult cancer patients found only a small number of studies conducted by social work researchers. The findings of the review are presented followed by a reflective discussion on the nature of knowledge-building and research knowledge for practice. Knowledge building is considered as a continuous, negotiated process within communities of practice focused on psychosocial perspectives that draw on a range of knowledge sources. Epistemology, worldviews and research orientations are considered along with the values and stance of social work, all of which create the domain of the practice-researcher.

Intrinsic speckle noise in in-line particle holography due to polydisperse and continuous particle sizes

NASA Astrophysics Data System (ADS)

Edwards, Philip J.; Hobson, Peter R.; Rodgers, G. J.

2000-08-01

In-line particle holography is subject to image deterioration due to intrinsic speckle noise. The resulting reduction in the signal to noise ratio (SNR) of the replayed image can become critical for applications such as holographic particle velocimetry (HPV) and 3D visualisation of marine plankton. Work has been done to extend the mono-disperse model relevant to HPV to include poly-disperse particle fields appropriate for the visualisation of marine plankton. Continuous and discrete particle fields are both considered. It is found that random walk statistics still apply for the poly-disperse case. The speckle field is simply the summation of the individual speckle patters due to each scatter size. Therefor the characteristic speckle parameter (which encompasses particle diameter, concentration and sample depth) is alos just the summation of the individual speckle parameters. This reduces the SNR calculation to the same form as for the mono-disperse case. For the continuous situation three distributions, power, exponential and Gaussian are discussed with the resulting SNR calcuated. The work presented here was performed as part of the Holomar project to produce a working underwater holographic camera for recording plankton.

Measuring pilot workload in a motion base simulator. III - Synchronous secondary task

NASA Technical Reports Server (NTRS)

Kantowitz, Barry H.; Bortolussi, Michael R.; Hart, Sandra G.

1987-01-01

This experiment continues earlier research of Kantowitz et al. (1983) conducted in a GAT-1 motion-base trainer to evaluate choice-reaction secondary tasks as measures of pilot work load. The earlier work used an asynchronous secondary task presented every 22 sec regardless of flying performance. The present experiment uses a synchronous task presented only when a critical event occurred on the flying task. Both two- and four-choice visual secondary tasks were investigated. Analysis of primary flying-task results showed no decrement in error for altitude, indicating that the key assumption necessary for using a choice secondary task was satisfied. Reaction times showed significant differences between 'easy' and 'hard' flight scenarios as well as the ability to discriminate among flight tasks.

Boughn, S

1992-05-01

Pay equity, the concept of equal pay for equal or comparable work, will continue to be of paramount importance to women as the 20th century draws to a close. While it might have been anticipated that women in academic settings would enjoy pay equity, clinical teaching in nursing education provides a model for gender discrimination as related to women's work. Elements of proposal development and a case study for contesting pay inequity are presented.

A heuristic neural network initialization scheme for modeling nonlinear functions in engineering mechanics: continuous development

NASA Astrophysics Data System (ADS)

Pei, Jin-Song; Mai, Eric C.

2007-04-01

This paper introduces a continuous effort towards the development of a heuristic initialization methodology for constructing multilayer feedforward neural networks to model nonlinear functions. In this and previous studies that this work is built upon, including the one presented at SPIE 2006, the authors do not presume to provide a universal method to approximate arbitrary functions, rather the focus is given to the development of a rational and unambiguous initialization procedure that applies to the approximation of nonlinear functions in the specific domain of engineering mechanics. The applications of this exploratory work can be numerous including those associated with potential correlation and interpretation of the inner workings of neural networks, such as damage detection. The goal of this study is fulfilled by utilizing the governing physics and mathematics of nonlinear functions and the strength of the sigmoidal basis function. A step-by-step graphical procedure utilizing a few neural network prototypes as "templates" to approximate commonly seen memoryless nonlinear functions of one or two variables is further developed in this study. Decomposition of complex nonlinear functions into a summation of some simpler nonlinear functions is utilized to exploit this prototype-based initialization methodology. Training examples are presented to demonstrate the rationality and effciency of the proposed methodology when compared with the popular Nguyen-Widrow initialization algorithm. Future work is also identfied.

Expanding Educators' Contributions to Continuous Quality Improvement of American Board of Medical Specialties Maintenance of Certification.

Nora, Lois Margaret; Pouwels, Mellie Villahermosa; Irons, Mira

2016-01-01

The American Board of Medical Specialties board certification has transformed into a career-long process of learning, assessment, and performance improvement through its Program for Maintenance of Certification (MOC). Medical educators across many medical professional organizations, specialty societies, and other institutions have played important roles in shaping MOC and tailoring its overarching framework to the needs of different specialties. This Commentary addresses potential barriers to engagement in work related to MOC for medical school (MS) and academic health center (AHC) educators and identifies reasons for, and ways to accomplish, greater involvement in this work. The authors present ways that medical and other health professions educators in these settings can contribute to the continuous improvement of the MOC program including developing educational and assessment activities, engaging in debate about MOC, linking MOC with institutional quality improvement activities, and pursuing MOC-related scholarship. MS- and AHC-based educators have much to offer this still-young and continually improving program, and their engagement is sought, necessary, and welcomed.

[About the turning point in a nurse's life when giving up the profession. A qualitative-empirical study on the willingness to continue to work and on the conditions for continuing to work in the post-professional phase of life].

PubMed

Schöbel, Jacqueline; Rester, David; Them, Christa; Seeberger, Bernd

2010-10-01

Due to the increasing life expectancy and population ageing, the post-professional phase of life is becoming more and more important to the individual and to society as a whole. The perception of the potentials of elderly people and, hence, the call for self-directed and independent activities in the post-professional phase are becoming more intense. The relation between retirement and work in nurses has not been of scientific importance so far. This is primarily due to the assumption that nurses cannot or do not stay in their profession until retirement. However, nurses do manage to pursue their profession continuously and permanently until they reach the age of retirement. The aim of this qualitative research study is to investigate the post-professional phase of life of former nurses within the context of the profession pursued. The guiding research questions in this regard were: How do former nurses spend their retirement period? How do nurses use their nursing-related abilities and experiences in their postprofessional phase of life? What do nurses associate with their former profession in the post-professional phase of life? In one-to-one interviews, these questions were posed to eight retired nurses who had pursued their profession for many years. The assessment instruments used were a socio-demographic questionnaire, a guideline and a record from memory. All data were summarized and evaluated analytically with regard to their content according to Mayring (2008). The present article shows the partial results of the study on retirement and work in the post-professional life of nurses. The results indicate that the transition to retirement is often accompanied by problems, that retired nurses do not fundamentally refuse to continue to work and that the willingness to continue to work is subject to certain conditions. Reasons and conditions for and against profession-based post-professional activities were revealed. Consequentially, concepts for the systematic identification of potentials of nurses in their post-professional phase of life should be developed.

Previous research has presented work on sensor requirements, specifications, and testing, to evaluate the feasibility of increasing autonomous vehicle system speeds. Discussions included the theoretical background for determining sensor requirements, and the basic test setup and evaluation criteria for comparing existing and prototype sensor designs. This paper will present and discuss the continuation of this work. In particular, this paper will focus on analyzing the problem via a real-world comparison of various sensor technology testing results, as opposed to previous work that utilized more of a theoretical approach. LADAR/LIDAR, radar, visual, and infrared sensors are considered in this research. Results are evaluated against the theoretical, desired perception specifications. Conclusions for utilizing a suite of perception sensors, to achieve the goal of doubling ground vehicle speeds, is also discussed.

Honan, Meg

2015-01-01

Places of work have been completely transformed by innovations in mobile work tools and ever-present access to internet data. This article characterizes use patterns and provides preliminary considerations for productive and comfortable use of common mobile devices. Two surveys described trends in mobile work. In the first, ergonomics professionals who oversee programs reported common mobile devices, their users and what data is accessed. The second, an end user survey, explored common activities performed on mobile devices, duration of use and locations where mobile work is common. The survey results provide a baseline data point for the status of mobile work in early 2014. Research indicates that additional risks have been introduced to the neck, thumbs and hands when using mobile devices. Possible trends regarding device use and work locations emerge. Intervention studies provide some direction for the practitioner. Practical strategies are outlined to reduce exposure intensity and duration. Contemporary mobile work presents tremendous change and opportunity for ergonomists and researchers to keep pace with fitting the changing models of work to the person. Continued research is needed on current mobile device use patterns to better understand ergonomic risk exposure in this rapidly changing realm.

Towards a rigorous framework for studying 2-player continuous games.

PubMed

Shutters, Shade T

2013-03-21

The use of 2-player strategic games is one of the most common frameworks for studying the evolution of economic and social behavior. Games are typically played between two players, each given two choices that lie at the extremes of possible behavior (e.g. completely cooperate or completely defect). Recently there has been much interest in studying the outcome of games in which players may choose a strategy from the continuous interval between extremes, requiring the set of two possible choices be replaced by a single continuous equation. This has led to confusion and even errors in the classification of the game being played. The issue is described here specifically in relation to the continuous prisoners dilemma and the continuous snowdrift game. A case study is then presented demonstrating the misclassification that can result from the extension of discrete games into continuous space. The paper ends with a call for a more rigorous and clear framework for working with continuous games. Copyright © 2013 Elsevier Ltd. All rights reserved.

Work flow of signal processing data of ground penetrating radar case of rigid pavement measurements

DOE Office of Scientific and Technical Information (OSTI.GOV)

Handayani, Gunawan

The signal processing of Ground Penetrating Radar (GPR) requires a certain work flow to obtain good results. Even though the Ground Penetrating Radar data looks similar with seismic reflection data, but the GPR data has particular signatures that the seismic reflection data does not have. This is something to do with coupling between antennae and the ground surface. Because of this, the GPR data should be treated differently from the seismic signal data processing work flow. Even though most of the processing steps still follow the same work flow of seismic reflection data such as: filtering, predictive deconvolution etc. Thismore » paper presents the work flow of GPR processing data on rigid pavement measurements. The processing steps start from raw data, de-Wow process, remove DC and continue with the standard process to get rid of noises i.e. filtering process.

Human area MT+ shows load-dependent activation during working memory maintenance with continuously morphing stimulation.

PubMed

Galashan, Daniela; Fehr, Thorsten; Kreiter, Andreas K; Herrmann, Manfred

2014-07-11

Initially, human area MT+ was considered a visual area solely processing motion information but further research has shown that it is also involved in various different cognitive operations, such as working memory tasks requiring motion-related information to be maintained or cognitive tasks with implied or expected motion.In the present fMRI study in humans, we focused on MT+ modulation during working memory maintenance using a dynamic shape-tracking working memory task with no motion-related working memory content. Working memory load was systematically varied using complex and simple stimulus material and parametrically increasing retention periods. Activation patterns for the difference between retention of complex and simple memorized stimuli were examined in order to preclude that the reported effects are caused by differences in retrieval. Conjunction analysis over all delay durations for the maintenance of complex versus simple stimuli demonstrated a wide-spread activation pattern. Percent signal change (PSC) in area MT+ revealed a pattern with higher values for the maintenance of complex shapes compared to the retention of a simple circle and with higher values for increasing delay durations. The present data extend previous knowledge by demonstrating that visual area MT+ presents a brain activity pattern usually found in brain regions that are actively involved in working memory maintenance.

On the lagrangian 1-form structure of the hyperbolic calogero-moser system

NASA Astrophysics Data System (ADS)

Jairuk, Umpon; Tanasittikosol, Monsit; Yoo-Kong, Sikarin

2017-06-01

In this work, we present the Lagrangian 1-form structure of the hyperbolic Calogero-Moser system in both discrete-time level and continuous-time level. The discrete-time hyperbolic Calogero-Moser system is obtained by considering pole reduction of the semi-discrete Kadomtsev-Petviashvili (KP) equation. Furthermore, it is shown that the hyperbolic Calogero-Moser system possesses the key relation, known as the discrete-time closure relation. This relation is a consequence of the compatibility property of the temporal Lax matrices. The continuous-time hierarchy of the hyperbolic Calogero-Moser system is obtained by taking two successive continuum limits, namely, the skewed limit and full limit. With these successive limits, the continuous-time closure relation is also obtained and is shown to hold at the continuous level.

Working outside the home is related to lower rates of breastfeeding initiation and duration. Enacted laws promote and support breastfeeding in working places. To determine factors associated to breastfeeding after returning to work. Anonymous questionnaires distributed among breastfeeding working mothers. The study subjects were 100 mothers. Most of them (77%) worked for the government. Fifty-six percent continued breastfeeding after returning to work. In 33% of the workplaces there was an area designated for milk extraction.Thirty-six percent of employers allowed the 30 minute periods mandated by law for extraction. Factors associated to continuing breastfeeding were: working in the private setting, having a place designated for extraction, knowing that employers were mandated to have such a place, being allowed time for extraction, and knowing the laws protecting breastfeeding. There is need for more education to working mothers about their rights to continue breastfeeding after returning to work.

Experiences of participating in return-to-work group programmes for people with musculoskeletal disorders: A focus group study.

The present study aimed to explore the experiences of individuals with musculoskeletal disorders (MSDs) who had participated in return-to-work group programmes (RTW-GPs) and to assess whether the programmes had had an impact on their work disability. Three focus group interviews and one individual interview were conducted involving 17 women (mean age = 47) with MSDs who had completed RTW-GPs. All interviews were audio-recorded, transcribed verbatim and analysed using thematic analyses. Participant experiences were categorised into three main themes: changed way of thinking, the importance of being able to work, and a changed lifestyle. The respondents said that participation in the RTW-GPs had enabled them to shift their focus from problems to opportunities. They had become more aware of strategies to enhance their energy levels and continue working. Several participants had reduced their work hours to achieve a better balance between work and daily life. Many participants had also changed their lifestyle habits, which had led to weight reduction, more energy and less pain. The study participants had attained a heightened awareness of what they could do to continue working. Many participants had introduced changes in their daily lives, with consequences for employment, social life and lifestyle. The findings suggest that RTW-GPs can help people with MSDs to remain in employment and prevent absenteeism. Copyright © 2017 John Wiley & Sons, Ltd.

We continue to use the Praesepe membership catalog presented in PaperII (Douglas+, 2014, J/ApJ/795/161), which includes 1130 cluster members with membership probabilities Pmem>=50% as calculated by Kraus & Hillenbrand (2007, J/AJ/134/2340) and 39 previously identified members too bright to be included by those authors in their catalog for the cluster. We assign these bright stars Pmem=100%. We also continue to use the photometry and stellar masses presented in Table 5 of Paper II. For most of our analysis, as in that work, we include only the 1099 stars with Pmem>=70%. K2 targeted Praesepe in its Campaign 5. We analyze the resulting long-cadence data for 794 Praesepe members. We present Prot for 677 K2 targets. Of these, 471 are new measurements. (3 data files).

Aqueveque, Pablo; Gutierrez, Cristopher; Saavedra, Francisco; Pino, Esteban J

2016-08-01

This work presents the design and implementation of a continuous monitoring device to control the health state of workers, for instance miners, at high altitudes. The extreme ambient conditions are harmful for peoples' health; therefore a continuous control of the workers' vital signs is necessary. The developed system includes physiological variables: electrocardiogram (ECG), respiratory activity and body temperature (BT), and ambient variables: ambient temperature (AT) and relative humidity (RH). The noninvasive sensors are incorporated in a t-shirt to deliver a functional device, and maximum comfort to the users. The device is able to continuously calculate heart rate (HR) and respiration rate (RR), and establish a wireless data transmission to a central monitoring station.

General practitioners' continuing education: a review of policies, strategies and effectiveness, and their implications for the future.

Smith, F; Singleton, A; Hilton, S

1998-10-01

The accreditation and provision of continuing education for general practitioners (GPs) is set to change with new proposals from the General Medical Council, the Government, and the Chief Medical Officer. To review the theories, policies, strategies, and effectiveness in GP continuing education in the past 10 years. A systematic review of the literature by computerized and manual searches of relevant journals and books. Educational theory suggests that continuing education (CE) should be work-based and use the learner's experiences. Audit can play an important role in determining performance and needs assessment, but at present is largely a separate activity. Educational and professional support, such as through mentors or co-tutors, has been successfully piloted but awaits larger scale evaluation. Most accredited educational events are still the postgraduate centre lecture, and GP Tutors have a variable role in CE management and provision. Controlled trials of CE strategies suggest effectiveness is enhanced by personal feedback and work prompts. Qualitative studies have demonstrated that education plays only a small part in influencing doctors' behavior. Maintaining good clinical practice is on many stakeholders' agendas. A variety of methods may be effective in CE, and larger scale trials or evaluations are needed.

Planning Under Continuous Time and Resource Uncertainty: A Challenge for AI

NASA Technical Reports Server (NTRS)

Bresina, John; Dearden, Richard; Meuleau, Nicolas; Smith, David; Washington, Rich; Clancy, Daniel (Technical Monitor)

2002-01-01

There has been considerable work in Al on decision-theoretic planning and planning under uncertainty. Unfortunately, all of this work suffers from one or more of the following limitations: 1) it relies on very simple models of actions and time, 2) it assumes that uncertainty is manifested in discrete action outcomes, and 3) it is only practical for very small problems. For many real world problems, these assumptions fail to hold. A case in point is planning the activities for a Mars rover. For this domain none of the above assumptions are valid: 1) actions can be concurrent and have differing durations, 2) there is uncertainty concerning action durations and consumption of continuous resources like power, and 3) typical daily plans involve on the order of a hundred actions. We describe the rover problem, discuss previous work on planning under uncertainty, and present a detailed. but very small, example illustrating some of the difficulties of finding good plans.

Occupational asthma caused by stainless steel welding fumes: a clinical study.

PubMed

Hannu, T; Piipari, R; Tuppurainen, M; Nordman, H; Tuomi, T

2007-01-01

The aim of the present study was to describe the cases of occupational asthma (OA) due to stainless steel welding fumes diagnosed at the Finnish Institute of Occupational Health during the period 1994-2003. OA was diagnosed according to patient history, lung function examinations and welding challenge tests with measurements of the forced expiratory volume in one second (FEV(1)) and peak expiratory flow (PEF) values. The present series comprised 34 patients, all male, with a mean age of 44.7 yrs (range 22-57), mainly working as welders. The mean duration of exposure was 22.4 yrs, and the mean duration of exposure before the onset of respiratory symptoms was 18 yrs. Dyspnoea was the most frequently reported work-related respiratory symptom. During the inhalation challenge tests, the mode of the asthmatic FEV(1)/PEF reaction was delayed in 16 (47%) patients, immediate in nine (26%) patients and dual (both immediate and delayed) in nine (26%) patients. In the follow-up assessment 6 months later, only six patients were considered able to continue performing welding tasks, whereas occupational injury pension was recommended for seven, and measures of vocational rehabilitation for 14 patients. In most cases, after the diagnosis of occupational asthma, the continuation of welding work was not possible.

Addressing holistic health and work empowerment through a body-mind-spirit intervention program among helping professionals in continuous education: A pilot study.

2016-01-01

To examine the effectiveness of a body-mind-spirit (BMS) intervention program in improving the holistic well-being and work empowerment among helping professionals in continuous education. Forty-four helping professionals, who were in their first-year part-time postgraduate study, participated in the present study. All participants attended a 3-day BMS intervention program which emphasized a holistic approach to health and well-being. Ratings on their levels of physical distress, daily functioning, affect, spirituality, and psychological empowerment at work were compared before and immediately after the intervention. Participants reported significantly lower levels of negative affect and physical distress, and were less spiritually disoriented after the intervention. Enhanced levels of daily functioning, positive affect, spiritual resilience, and tranquility were also reported. Results also suggested that participants were empowered at work, and specifically felt more able to make an impact on work outcomes. The 3-day BMS intervention program produced a positive and measurable effect on participants' holistic well-being and empowerment at work. Educators in related fields could incorporate holistic practices into the curriculum to better prepare the future practitioners, leading to better outcomes both to the professionals themselves and their clients or patients.

A synthesis of qualitative research exploring the barriers to staying in work with chronic musculoskeletal pain.

PubMed

Toye, Francine; Seers, Kate; Allcock, Nick; Briggs, Michelle; Carr, Eloise; Barker, Karen

2016-01-01

Qualitative research can help to advance our understanding, management and prevention of work disability. Our aim was to integrate qualitative research findings in order to increase our understanding of barriers to stay in work with chronic pain. We searched five electronic bibliographic databases until September 2012, supplemented by citation tracking and hand-searching. We used meta-ethnography to synthesis our findings. Central to meta-ethnography is identifying “concepts” and developing a conceptual model. Concepts were compared and organised into categories. The following categories can have an impact on the decision to remain in work: struggling to affirm myself as a good worker; balancing life and work in the face of unpredictable symptoms; my work colleagues don't believe me; the system does not facilitate return to work; the battle for legitimacy. Our innovation is to present an internationally relevant model based on a conceptual synthesis. This model highlights the adversarial work experience of people with chronic. The papers span 15 years of qualitative research. A significant finding is that these themes continue to pervade the current work environment for those in pain, and this has clear implications for education, social care and policy. People with chronic pain face an adversarial struggle to maintain their credibility at work. Strategies to maintain personal credibility can have an adverse effect on working lives. Changes at a systems level are needed to facilitate continuance and return to work. Cultural changes in the way that we view people with pain would help to keep people in work.

Robust stability bounds for multi-delay networked control systems

NASA Astrophysics Data System (ADS)

Seitz, Timothy; Yedavalli, Rama K.; Behbahani, Alireza

2018-04-01

In this paper, the robust stability of a perturbed linear continuous-time system is examined when controlled using a sampled-data networked control system (NCS) framework. Three new robust stability bounds on the time-invariant perturbations to the original continuous-time plant matrix are presented guaranteeing stability for the corresponding discrete closed-loop augmented delay-free system (ADFS) with multiple time-varying sensor and actuator delays. The bounds are differentiated from previous work by accounting for the sampled-data nature of the NCS and for separate communication delays for each sensor and actuator, not a single delay. Therefore, this paper expands the knowledge base in multiple inputs multiple outputs (MIMO) sampled-data time delay systems. Bounds are presented for unstructured, semi-structured, and structured perturbations.

Patients attending a casualty department often have diseases or injuries needing urgent medical attention. Early and correct diagnosis and treatment may be of major importance for the medical outcome. The continuity of staff is often low, with many doctors and nurses working part time. This may represent a threat to the quality of the medical work. Quality assurance at a casualty department through good training, introduction of written rules, a good flow of information to the staff and local licensing of doctors are factors which can assure that the quality of the medical service remains the best. This paper presents the work done at The Tromsø Municipal Casualty Department to assure the quality of the medical service to the population.

This study examines the association of work and health-related characteristics with the intention to continue working after the age of 65 years. Data were from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2), a nationally representative population survey, including 1854 employees aged 45-64 years; 29.0% reported the intention to continue working after 65 years. Lower education, more adverse psychosocial working conditions and any physical disorder were negatively associated with this intention. Mental disorders were not associated. These findings highlight the importance of favourable working conditions and good physical health in relation to employees' intention to continue working after 65 years. © The Author 2014.

Lauderbach, Lisa M.; Souers, P. Clark; Garcia, Frank; Vitello, Peter; Vandersall, Kevin S.

2009-12-01

Experiments were performed using detonating LX-17 (92.5% TATB, 7.5% Kel-F by weight) charges with various width transverse air gaps with manganin peizoresistive in-situ gauges present. The experiments, performed with 25 mm diameter by 25 mm long LX-17 pellets with the transverse air gap in between, showed that transverse gaps up to about 3 mm could be present without causing the detonation wave to fail to continue as a detonation. The Tarantula/JWL++ code was utilized to model the results and compare with the in-situ gauge records with some agreement to the experimental data with additional work needed for a better match to the data. This work will present the experimental details as well as comparison to the model results.

Array heterogeneity prevents catastrophic forgetting in infants

PubMed Central

Zosh, Jennifer M.; Feigenson, Lisa

2015-01-01

Working memory is limited in adults and infants. But unlike adults, infants whose working memory capacity is exceeded often fail in a particularly striking way: they do not represent any of the presented objects, rather than simply remembering as many objects as they can and ignoring anything further (Feigenson & Carey 2003, 2005). Here we explored the nature of this “catastrophic forgetting,” asking whether stimuli themselves modulate the way in which infants’ memory fails. We showed 13-month old infants object arrays that either were within or that exceeded working memory capacity—but, unlike previous experiments, presented objects with contrasting features. Although previous studies have repeatedly documented infants’ failure to represent four identical hidden objects, in Experiments 1 and 2 we found that infants who saw four contrasting objects hidden, and then retrieved just two of the four, successfully continued searching for the missing objects. Perceptual contrast between objects sufficed to drive this success; infants succeeded regardless of whether the different objects were contrastively labeled, and regardless of whether the objects were semantically familiar or completely novel. In Experiment 3 we explored the nature of this surprising success, asking whether array heterogeneity actually expanded infants’ working memory capacity or rather prevented catastrophic forgetting. We found that infants successfully continued searching after seeing four contrasting objects hidden and retrieving two of them, but not after retrieving three of them. This suggests that, like adults, infants were able to remember up to, but not beyond, the limits of their working memory capacity when representing heterogeneous arrays. PMID:25543889

Men who work at age 70 or older.

Ozawa, Martha N; Lum, Terry Y

2005-01-01

The federal policy on older workers has shifted from the encouragement of early withdrawal from the labor force to the encouragement of continuous participation in the labor force. In this light, it is instructive to investigate the backgrounds of elderly people who work at age 70 or older. This article presents the findings of a study, using data from the 1993 Asset and Health Dynamics of the Oldest Old Study, that investigated the effects of health, economic conditions (net worth, employer-provided pensions, and supplemental medical insurance coverage), education, and spouse's work status on the probability of working among men aged 70 or older. The study addressed the probability of working, the probability of working fulltime and of working part-time, and the probability of being self-employed and of being employed by others. Implications for policy are discussed.

Is Fly in/Fly out (FIFO) a viable interim solution to address remote medical workforce shortages?

PubMed

Margolis, Stephen A

2012-01-01

Geographically remote regions of Australia experience a higher degree of socioeconomic inequality and health inequity, amid poor resourcing and extreme climatic conditions, when compared with their more urban counterparts. Doctors with the knowledge, skills and interest in remote work remain a scarce resource, with only 58 practitioners per 100,000 people versus 196/100,000 in metropolitan areas. Pending the arrival of the full complement of long-term remote medical workforce, an alternative solution that has so far received little attention but could provide near equivalence to resident doctors is the 'fly in/fly out' (FIFO) model. Specifically, where one doctor has a continuous relationship with one town or community, albeit spending their rostered time off away from this location, rather than continuity of service with different doctors each time. In this model, doctors spend a fixed number of days at work geographically remote from their home and families, with logistical support (eg housing, transport) provided, followed by a fixed number of days back at home not working. This provides a the doctor with the benefits of remote clinical work plus guaranteed time off at home, a more acceptable roster than in many remote locations at present. This also avoids the complex issue of experienced doctors having to leave remote areas mid-career for the well-documented reasons of spouse employment and children's education, as well as providing easier access to professional development activities. The author followed this path and remains a FIFO doctor after 7 years of continuous service. For FIFO to be effective, there needs to be a commitment from the sponsoring organisation for short, balanced, flexible, family friendly rosters and a positive organizational structure with effective communication between management and front line staff. Evidence shows that families and children with healthy family functioning, who are able to balance separateness and togetherness and are able to readily adjust when circumstances move from stability through change, and have strong communication skills, cope well with FIFO work. The author's employer actively supports his FIFO work arrangements. Although FIFO presents challenges and is not for everyone, it may be time for organisations providing medical care to remote Australia to further consider this option. Allowing mid-career doctors experienced in remote medicine to continue remote clinical practice when they move to the city for family reasons would provide an immediate benefit to remote communities. Notwithstanding the challenges, perhaps it is time to consider the option of FIFO to address ongoing workforce shortages?

Working beyond 65: predictors of late retirement for women and men MBAs.

Frieze, Irene Hanson; Olson, Josephine E; Murrell, Audrey J

2011-01-01

Comparisons of those who planned to continue working after the age of 65 with those who did not were made for 145 women and 414 men working in managerial fields. All received MBA degrees between the years of 1973 and 1982. About 20% definitely wanted to work after age 65. More positive views of work were predictive of wanting to continue working as was having nontraditional gender-role attitudes. Men who planned to continue working were particularly likely to have a spouse wanting to work past the age of 65. Several other factors appeared to operate differently for women and men.

The experiences of new graduate midwives working in midwifery continuity of care models in Australia.

PubMed

Cummins, Allison M; Denney-Wilson, E; Homer, C S E

2015-04-01

midwifery continuity of care has been shown to be beneficial to women through reducing interventions and other maternal and neonatal morbidity. In Australia, numerous government reports recognise the importance of midwifery models of care that provide continuity. Given the benefits, midwives, including new graduate midwives, should have the opportunity to work in these models of care. Historically, new graduates have been required to have a number of years׳ experience before they are able to work in these models of care although a small number have been able to move into these models as new graduates. to explore the experiences of the new graduate midwives who have worked in midwifery continuity of care, in particular, the support they received; and, to establish the facilitators and barriers to the expansion of new graduate positions in midwifery continuity of care models. a qualitative descriptive study was undertaken framed by the concept of continuity of care. the new graduate midwives valued the relationship with the women and with the group of midwives they worked alongside. The ability to develop trusting relationships, consolidate skills and knowledge, be supported by the group and finally feeling prepared to work in midwifery continuity of care from their degree were all sub-themes. All of these factors led to the participants feeling as though they were 'becoming a real midwife'. this is the first study to demonstrate that new graduate midwives value working in midwifery continuity of care - they felt well prepared to work in this way from their degree and were supported by midwives they worked alongside. The participants reported having more confidence to practice when they have a relationship with the woman, as occurs in these models. Copyright © 2015 Elsevier Ltd. All rights reserved.

Fabrication of brittle materials -- current status

DOE Office of Scientific and Technical Information (OSTI.GOV)

Scattergood, R.O.

The research initiatives in the area of precision fabrication will be continued in the upcoming year. Three students, T. Bifano (PhD), P. Blake (PhD) and E. Smith (MS), finished their research programs in the last year. Sections 13 and 14 will summarize the essential results from the work of the Materials Engineering students Blake and Smith. Further details will be presented in forthcoming publications that are now in preparation. The results from Bifano`s thesis have been published in adequate detail and need not be summarized further. Three new students, S. Blackley (MS), H. Paul (PhD), and S. Smith (PhD) havemore » joined the program and will continue the research efforts in precision fabrication. The programs for these students will be outlined in Sections 15 and 16. Because of the success of the earlier work in establishing new process models and experimental techniques for the study of diamond turning and diamond grinding, the new programs will, in part, build upon the earlier work. This is especially true for investigations concerned with brittle materials. The basic understanding of material response of nominally brittle materials during machining or grinding operations remains as a challenge. The precision fabrication of brittle materials will continue as an area of emphasis for the Precision Engineering Center.« less

Coproduction of volatiles and metals from extraterrestrial materials

NASA Technical Reports Server (NTRS)

Lewis, John S.

1991-01-01

Two main efforts in support of the general goals of SERC/culpr are presented. Investigations of processes for the coproduction of metals from extra-terrestrial materials in conjunction with plausible schemes for oxygen extraction continue. The principal emphasis was on the extraction and purification of iron from the ilmenite reduction process for oxygen, from the cathode metal deposits made in the magma electrolysis process for oxygen, and from native ferrous metal alloys on the moon and asteroids. All work on the separation and purification of ferrous metals was focussed upon the gaseous carbonyl process, a scheme that involves only temperatures attainable by passive thermal control. The exploration of a variety of schemes was initiated, involving the use of several different propulsion options and both propulsive and aerobraking capture at earth, for return of extraterrestrial resources to earth orbits. In addition, the search for new opportunities in space resource utilization continues. Examples include the continuation of work underway on: (1) the feasibility of locating solar power satellites in highly eccentric earth orbit; (2) the energetics of extracting the potential clean fusion fuel He-3 from the atmosphere for return to earth; and (3) the utility of a nuclear steam rocket (using non-terrestrial water as the working fluid) for transportation in the inner solar system.

American social work, corrections and restorative justice: an appraisal.

PubMed

Gumz, Edward J

2004-08-01

Social work played an active role in American corrections until the 1980s when the ethic of rehabilitation began to give way to a more conservative doctrine of retribution. Changes in the field of social work, characterized by preference of social workers to work only with certain populations, contributed to social work's diminishment in corrections. Although efforts at rehabilitation continue in corrections, the concept of restorative justice that emphasizes assisting victims, communities, and offenders in dealing with the consequences of crime is gaining acceptance in the field of corrections in the United States and in other countries. This study explored social work's presence in corrections, the decline of that presence, and how the concept of restorative justice can invigorate social work within the field of corrections. Several examples of social work's contemporary efforts to use the concept of restorative justice in the United Kingdom are presented.

Non-verbal numerical cognition: from reals to integers.

PubMed

Gallistel; Gelman

2000-02-01

Data on numerical processing by verbal (human) and non-verbal (animal and human) subjects are integrated by the hypothesis that a non-verbal counting process represents discrete (countable) quantities by means of magnitudes with scalar variability. These appear to be identical to the magnitudes that represent continuous (uncountable) quantities such as duration. The magnitudes representing countable quantity are generated by a discrete incrementing process, which defines next magnitudes and yields a discrete ordering. In the case of continuous quantities, the continuous accumulation process does not define next magnitudes, so the ordering is also continuous ('dense'). The magnitudes representing both countable and uncountable quantity are arithmetically combined in, for example, the computation of the income to be expected from a foraging patch. Thus, on the hypothesis presented here, the primitive machinery for arithmetic processing works with real numbers (magnitudes).

Non-linear continuous time random walk models★

NASA Astrophysics Data System (ADS)

Stage, Helena; Fedotov, Sergei

2017-11-01

A standard assumption of continuous time random walk (CTRW) processes is that there are no interactions between the random walkers, such that we obtain the celebrated linear fractional equation either for the probability density function of the walker at a certain position and time, or the mean number of walkers. The question arises how one can extend this equation to the non-linear case, where the random walkers interact. The aim of this work is to take into account this interaction under a mean-field approximation where the statistical properties of the random walker depend on the mean number of walkers. The implementation of these non-linear effects within the CTRW integral equations or fractional equations poses difficulties, leading to the alternative methodology we present in this work. We are concerned with non-linear effects which may either inhibit anomalous effects or induce them where they otherwise would not arise. Inhibition of these effects corresponds to a decrease in the waiting times of the random walkers, be this due to overcrowding, competition between walkers or an inherent carrying capacity of the system. Conversely, induced anomalous effects present longer waiting times and are consistent with symbiotic, collaborative or social walkers, or indirect pinpointing of favourable regions by their attractiveness.

1992-07-01

The aging of the population is accompanied by profound changes in life cycles, and it calls into question the models of institutional relationship between education, work and leisure time. After reviewing some concepts of aging, the author places the "training-work-retirement" triad in the context of the transformation of paid work and the new scenarios of ways in which people finally leave the labour market. Two questions are then asked: In what way may aging populations change the demand for adult continuing education? And, what is the significance of the present educational response to the problems posed by the aging of the population?

The nursing profession faces continuous transformations demonstrating the importance of professional continuing education to extend knowledge following technological development without impairing quality of care. Nursing assistants and technicians account for nearly 80% of nursing professionals in Brazil and are responsible for uninterrupted patient care. Extensive knowledge improvement is needed to achieve excellence in nursing care. The objective was to develop and evaluate a continuing education program for nursing technicians at a pediatric cardiac intensive care unit (PCICU) using a virtual learning environment entitled EDUCATE. From July to September 2015, a total of 24 nursing technicians working at the PCICU at a children's hospital located in the northwestern region of São Paulo state (Brazil) fully participated in the continuing education program developed in a virtual learning environment using Wix platform, allowing access to video classes and pre- and post-training theoretical evaluation questionnaires outside the work environment. The evaluation tools recorded participants' knowledge evolution, technological difficulties, educational, and overall rating. Knowledge development was descriptively presented as positive in more than 66.7%. Content and training were considered "excellent" by most participants and 90% showed an interest in the use of technological resources. Technical difficulties were found and quickly resolved by 40% of participants including Internet access, login, and lack of technical expertise. The continuing education program using a virtual learning environment positively contributed to the improvement in theoretical knowledge of nursing technicians in PCICU.

Continuous API-crystal coating via coacervation in a tubular reactor.

Besenhard, M O; Thurnberger, A; Hohl, R; Faulhammer, E; Rattenberger, J; Khinast, J G

2014-11-20

We present a proof-of-concept study of a continuous coating process of single API crystals in a tubular reactor using coacervation as a microencapsulation technique. Continuous API crystal coating can have several advantages, as in a single step (following crystallization) individual crystals can be prepared with a functional coating, either to change the release behavior, to protect the API from gastric juice or to modify the surface energetics of the API (i.e., to tailor the hydrophobic/hydrophilic characteristics, flowability or agglomeration tendency, etc.). The coating process was developed for the microencapsulation of a lipophilic core material (ibuprofen crystals of 20 μm- to 100 μm-size), with either hypromellose phthalate (HPMCP) or Eudragit L100-55. The core material was suspended in an aqueous solution containing one of these enteric polymers, fed into the tubing and mixed continuously with a sodium sulfate solution as an antisolvent to induce coacervation. A subsequent temperature treatment was applied to optimize the microencapsulation of crystals via the polymer-rich coacervate phase. Cross-linking of the coating shell was achieved by mixing the processed material with an acidic solution (pH<3). Flow rates, temperature profiles and polymer-to-antisolvent ratios had to be tightly controlled to avoid excessive aggregation, leading to pipe plugging. This work demonstrates the potential of a tubular reactor design for continuous coating applications and is the basis for future work, combining continuous crystallization and coating.

COLLABORATE©, Part IV: Ramping Up Competency-Based Performance Management.

PubMed

Treiger, Teresa M; Fink-Samnick, Ellen

The purpose of this fourth part of the COLLABORATE© article series provides an expansion and application of previously presented concepts pertaining to the COLLABORATE paradigm of professional case management practice. The model is built upon a value-driven foundation that: PRIMARY PRACTICE SETTING(S):: Applicable to all health care sectors where case management is practiced. As an industry, health care continues to evolve. Terrain shifts and new influences continually surface to challenge professional case management practice. The need for top-performing and nimble professionals who are knowledgeable and proficient in the workplace continues to challenge human resource departments. In addition to care setting knowledge, professional case managers must continually invest in their practice competence toolbox to grow skills and abilities that transcend policies and processes. These individuals demonstrate agility in framing (and reframing) their professional practice to facilitate the best possible outcomes for their clients. Therefore, the continued emphasis on practice competence conveyed through the performance management cycle is an essential ingredient to performance management focused on customer service excellence and organizational improvement. Professional case management transcends professional disciplines, educational levels, and practice settings. Business objectives continue to drive work process and priorities in many practice settings. However, competencies that align with regulatory and accreditation requirements should be the critical driver for consistent, high-quality case management practice. Although there is inherent value in what various disciplines bring to the table, this advanced model unifies behind case management's unique, strengths-based identity instead of continuing to align within traditional divisions (e.g., discipline, work setting, population served). This model fosters case management's expanding career advancement opportunities.

Continuing professional development and the charity paradigm: interrelated individual, collective and organisational issues about continuing professional development.

PubMed

Munro, Kathleen M

2008-11-01

This paper aims to highlight some issues and tensions that currently challenge the profession, individual nurses and their employers when considering the need for continuing professional development. The Nursing and Midwifery Council states the professional requirements for continuing professional development. However the nature and type required seems to be determined by the individual on the one hand and the organisation on the other, rather than an integral part of professional activity within the context of work. This can lead to a mismatch between personal and organisational goals. Views emerged from participants in a previous case study that focused on learning through work, about support available to nurses for professional development. The perceptions of nurses and their managers about learning through work were explored, using semi structured interviews, picture mapping and structured interviews. The 'Charity Paradigm' is presented as an outcome of major issues within an organisation. It underpins negative perceptions of individuals about employer support of continuing professional development. It is suggested that there is a need for collaborative collective approaches to structured development in order to meet both individual and organisational needs. This is also advocated in order to achieve life long learning and transformational learning within an organisation. The tension between individual personal ambitions and employer demands can adversely affect the professional development of the practitioner and the organisation that employs them. The personal perspectives of nurses and managers about learning within their organisation are therefore important to acknowledge in terms of positive and negative influences. It is also necessary to recognise the contribution of the employer as well as the identifiable charitable contribution of individual practitioners and the input from external contributors to the organisation.

Continuity of midwifery care contributes to significant positive outcomes for women and babies. There is a perception that providing continuity of care may negatively impact on the wellbeing and professional lives of midwives. To compare the emotional and professional wellbeing as well as satisfaction with time off and work-life balance of midwives providing continuity of care with midwives not providing continuity. Online survey. Measures included; Copenhagen Burnout Inventory (CBI); Depression, Anxiety and Stress Scale-21; and Perceptions of Empowerment in Midwifery Scale (PEMS-Revised). The sample (n=862) was divided into two groups; midwives working in continuity (n=214) and those not working in continuity (n=648). Mann Whitney U tests were used to compare the groups. The continuity group had significantly lower scores on each of the burnout subscales (CBI Personal p=.002; CBI Work p<.001; CBI Client p<.001) and Anxiety (p=.007) and Depression (p=.004) sub-scales. Midwives providing continuity reported significantly higher scores on the PEMs Autonomy/Empowerment subscale (p<.001) and the Skills and Resources subscale (p=.002). There was no difference between the groups in terms of satisfaction with time off and work-life balance. Our results indicate that providing continuity of midwifery care is also beneficial for midwives. Conversely, midwives working in shift-based models providing fragmented care are at greater risk of psychological distress. Maternity service managers should feel confident that re-orientating care to align with the evidence is likely to improve workforce wellbeing and is a sustainable way forward.

Model-based reasoning for system and software engineering: The Knowledge From Pictures (KFP) environment

NASA Technical Reports Server (NTRS)

Bailin, Sydney; Paterra, Frank; Henderson, Scott; Truszkowski, Walt

1993-01-01

This paper presents a discussion of current work in the area of graphical modeling and model-based reasoning being undertaken by the Automation Technology Section, Code 522.3, at Goddard. The work was initially motivated by the growing realization that the knowledge acquisition process was a major bottleneck in the generation of fault detection, isolation, and repair (FDIR) systems for application in automated Mission Operations. As with most research activities this work started out with a simple objective: to develop a proof-of-concept system demonstrating that a draft rule-base for a FDIR system could be automatically realized by reasoning from a graphical representation of the system to be monitored. This work was called Knowledge From Pictures (KFP) (Truszkowski et. al. 1992). As the work has successfully progressed the KFP tool has become an environment populated by a set of tools that support a more comprehensive approach to model-based reasoning. This paper continues by giving an overview of the graphical modeling objectives of the work, describing the three tools that now populate the KFP environment, briefly presenting a discussion of related work in the field, and by indicating future directions for the KFP environment.

The Permanent Service for Mean Sea Level (PSMSL) is the internationally recognised global sea level data bank for long term sea level change information from tide gauges. Established in 1933, the PSMSL continues to be responsible for the collection, publication, analysis and interpretation of sea level data. The PSMSL operates under the auspices of the International Council for Science (ICSU) and is one of the main data centres for both the International Association for the Physical Sciences of the Oceans (IAPSO) and the International Association of Geodesy (IAG). The PSMSL continues to work closely with other members of the sea level community through the Intergovernmental Oceanographic Commission's Global Sea Level Observing System (GLOSS). Currently, the PSMSL data bank for monthly and annual sea level data holds over 65,000 station-years of data from over 2200 stations. Data from each site are carefully quality controlled and, wherever possible, reduced to a common datum, whose stability is monitored through a network of geodetic benchmarks. Last year, the PSMSL also made available a data bank of measurements taken from in-situ ocean bottom pressure recorders from over 60 locations across the globe. Here, we present an overview of the data available at the PSMSL, and describe some of the ongoing work that aims to provide more information to users of our data. In particular, we describe the ongoing work with the Système d'Observation du Niveau des Eaux Littorales (SONEL) to use measurements from continuous GNSS records located near tide gauges to provide PSMSL data within a geocentric reference frame. We also highlight changes to the method used to present estimated sea level trends to account for seasonal cycles and autocorrelation in the data, and provide an estimate of the error of the trend.

Discrete Sparse Coding.

PubMed

Exarchakis, Georgios; Lücke, Jörg

2017-11-01

Sparse coding algorithms with continuous latent variables have been the subject of a large number of studies. However, discrete latent spaces for sparse coding have been largely ignored. In this work, we study sparse coding with latents described by discrete instead of continuous prior distributions. We consider the general case in which the latents (while being sparse) can take on any value of a finite set of possible values and in which we learn the prior probability of any value from data. This approach can be applied to any data generated by discrete causes, and it can be applied as an approximation of continuous causes. As the prior probabilities are learned, the approach then allows for estimating the prior shape without assuming specific functional forms. To efficiently train the parameters of our probabilistic generative model, we apply a truncated expectation-maximization approach (expectation truncation) that we modify to work with a general discrete prior. We evaluate the performance of the algorithm by applying it to a variety of tasks: (1) we use artificial data to verify that the algorithm can recover the generating parameters from a random initialization, (2) use image patches of natural images and discuss the role of the prior for the extraction of image components, (3) use extracellular recordings of neurons to present a novel method of analysis for spiking neurons that includes an intuitive discretization strategy, and (4) apply the algorithm on the task of encoding audio waveforms of human speech. The diverse set of numerical experiments presented in this letter suggests that discrete sparse coding algorithms can scale efficiently to work with realistic data sets and provide novel statistical quantities to describe the structure of the data.

Downward continuation of airborne gravity data by means of the change of boundary approach

NASA Astrophysics Data System (ADS)

Mansi, A. H.; Capponi, M.; Sampietro, D.

2018-03-01

Within the modelling of gravity data, a common practice is the upward/downward continuation of the signal, i.e. the process of continuing the gravitational signal in the vertical direction away or closer to the sources, respectively. The gravity field, being a potential field, satisfies the Laplace's equation outside the masses and this means that it allows to unambiguously perform this analytical continuation only in a source-free domain. The analytical continuation problem has been solved both in the space and spectral domains by exploiting different algorithms. As well known, the downward continuation operator, differently from the upward one, is an unstable operator, due to its spectral characteristics similar to those of a high-pass filter, and several regularization methods have been proposed in order to stabilize it. In this work, an iterative procedure to downward/upward continue the gravity field observations, acquired at different altitudes, is proposed. This methodology is based on the change of boundary principle and it has been expressively thought for aerogravimetric observations for geophysical exploration purposes. Within this field of application, usually several simplifications can be applied, basically due to the specific characteristics of the airborne surveys which are usually flown at almost constant altitude as close as possible to the terrain. For instance, these characteristics, as shown in the present work, allow to perform the downward continuation without the need of any regularization. The goodness of the proposed methodology has been evaluated by means of a numerical test on real data, acquired in the South of Australia. The test shows that it is possible to move the aerogravimetric data, acquired along tracks with a maximum height difference of about 250 m, with accuracies of the order of 10^{-3} mGal.

The TPHOLs International Conference serves as a venue for the presentation of work in theorem proving in higher-order logics and related areas in deduction, formal specification, software and hardware verification, and other applications. Fourteen papers were submitted to Track B (Work in Progress), which are included in this volume. Authors of Track B papers gave short introductory talks that were followed by an open poster session. The FCM 2002 Workshop aimed to bring together researchers working on the formalisation of continuous mathematics in theorem proving systems with those needing such libraries for their applications. Many of the major higher order theorem proving systems now have a formalisation of the real numbers and various levels of real analysis support. This work is of interest in a number of application areas, such as formal methods development for hardware and software application and computer supported mathematics. The FCM 2002 consisted of three papers, presented by their authors at the workshop venue, and one invited talk.

"I WILL SURVIVE" A Construct Validation Study on the Measurement of Sustainable Employability Using Different Age Conceptualizations.

PubMed

Le Blanc, Pascale M; Van der Heijden, Beatrice I J M; Van Vuuren, Tinka

2017-01-01

Though the importance of sustainable employability throughout people's working life is undisputed, up till now only one attempt for a conceptual definition has been made (van der Klink et al., 2016). Following the suggestions to further refine and improve this definition recently put forward by Fleuren et al. (2016), we propose an approach to sustainable employability that is based on the Ability-Motivation-Opportunity (AMO) framework, and incorporates three indicators: the ability, the motivation, and the opportunity to continue working, respectively. As sustainable employability is considered to be an important aspect of successful aging at work, this study used four different conceptualizations of aging at work to set up convergent and divergent validity of our operationalization of sustainable employability: calendar age, organizational age (job and organizational tenure), functional age (work ability), and life-span age (partner and children). We formulated several hypotheses that were tested by analyzing data from an online survey among 180 employees from Dutch public service organizations who filled out a questionnaire on different age concepts, and their ability, motivation, and opportunity to continue working. Multiple regression analyses were performed, and results showed that the four conceptualizations of aging were differently related to the three indicators of sustainable employability. Life-span age, in terms of having children, had the strongest negative relationship with the ability to continue working, organizational age (i.e., organizational tenure) had the strongest negative relationship with the motivation to continue working, and functional age had the strongest negative relationship with the opportunity to continue working. Moreover, functional age was significantly negatively related to the other two indicators of sustainable employability too, while life-span age appeared to enhance the ability and motivation to continue working (in terms of having children) and the perceived opportunity to continue working (in terms of having a partner). Calendar age was only important for the opportunity to continue working and appeared to have a negative association with this outcome variable. These results lend support to our proposed operationalization of sustainable employability by showing that the three indicators are differently related to different age conceptualizations thus expanding previous research on the conceptualization of sustainable employability.

[Working women with chronic musculoskeletal pain: a case series].

PubMed

Ordóñez-Hernández, Cecilia Andrea; Contreras-Estrada, Mónica Isabel; Soltero-Avelar, Ruben

2015-10-01

This study aimed to analyze the experience of working women suffering from chronic musculoskeletal pain, using a qualitative design with a phenomenological approach. The technique drew on in-depth interviews with five working women that presented to the orthopedics and neurosurgery departments of a hospital in Guadalajara, Mexico, with a complaint of musculoskeletal pain for more than six months. The study showed that the women felt rejection, segregation, discrimination, lack of support at the workplace, and feelings of frustration and powerlessness related to their health condition. The women also perceived as a barrier the lack of efficiency in disability proceedings and job reintegration or relocation. Financial and family responsibilities were their main reason for continuing to work despite their chronic musculoskeletal pain.

Treatment of end-stage renal disease with continuous ambulatory peritoneal dialysis in rural Guatemala

PubMed Central

Moore, Jillian; Garcia, Pablo; Flood, David

2018-01-01

A 42-year-old indigenous Maya man presented to a non-profit clinic in rural Guatemala with signs, symptoms and laboratory values consistent with uncontrolled diabetes. Despite appropriate treatment, approximately 18 months after presentation, he was found to have irreversible end-stage renal disease (ESRD) of uncertain aetiology. He was referred to the national public nephrology clinic and subsequently initiated home-based continuous ambulatory peritoneal dialysis. With primary care provided by the non-profit clinic, his clinical status improved on dialysis, but socioeconomic and psychological challenges persisted for the patient and his family. This case shows how care for people with ESRD in low- and middle-income countries requires scaling up renal replacement therapy and ensuring access to primary care, mental healthcare and social work services.

Modification of the Stress-Strain Curve for High-Strength Line Pipe Steel

NASA Astrophysics Data System (ADS)

Jonsson, Katherine

2013-01-01

This thesis presents work performed to improve the work hardening behaviour of an X80 microalloyed steel through various Interrupted Thermal Treatments (ITT). The aim of this work was to determine the relationships between thermal history, microstructure and mechanical properties through both qualitative and quantitative measures. Prior to the ITT experiments, a continuous cooling transformation (CCT) diagram was constructed under no-strain conditions to identify the transformation temperatures and products that are achievable in X80 steel. The thermal treatments were applied using a Gleeble thermal-mechanical simulator to generate a variety of microstructures in various fractions and morphologies. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to investigate and quantify the microstructures in terms of phase fraction and grain size. The ITT experiments successfully generated microstructures comprised of ferrite, bainitic ferrite, martensite and martensite-austenite (M-A) without the addition of strain. The effect of cooling rates, interrupt temperature, re-heat temperature and hold times were investigated and the mechanical performance was correlated with the quantified microstructures. Although the ITT experiments did not improve the strength relative to a continuously cooled sample, the work hardening coefficient was increased as a result of the interrupted thermal treatments.

The relationship between healthy work environments and retention of nurses in a hospital setting.

Ritter, Desiree

2011-01-01

The purpose of the present paper was to determine the effect a healthy work environment has on the retention of nurses in a hospital setting. There is a nursing shortage that has been ongoing and is expected to continue, resulting in challenges for the healthcare system in the United States. The significance of this issue is the impact the nursing shortage will have on healthcare organizations and patients. The present paper included an extensive review of the current literature. The literature reviewed encompassed scholarly peer-reviewed journal articles. This article focused on nurses, work environments and the impact of the work environments on retention. Important issues that emerged from this analysis were the dangers of an unhealthy environment, the impact a healthy work environment has on patient outcomes and retention, the Magnet link to healthy work environments and the manager's role in creating and sustaining a healthy work environment. The literature provided evidence of the link between healthy work environments and the retention of nurses in a hospital setting. The implications for management are to implement changes now to create a healthy work environment that will recruit and retain nurses to secure their position in the future. © 2010 The Author.

Muniz, German; Alum, Jorge

1996-02-01

In the present work are given the results of the application of laser metal surface hardening techniques using a cw carbon dioxide laser as an energy source on steel 65 G. The laser heat treatment results are presented theoretically and experimentally. Continuous wave carbon dioxide laser of 0.6, 0.3, and 0.4 kW were used. A physical model for the descriptions of the thermophysical laser metal interactions process is given and a numerical algorithm is used to solve this problem by means of the LHT code. The results are compared with the corresponding experimental ones and a very good agreement is observed. The LHT code is able to do predictions of transformation hardening by laser heating. These results will be completed with other ones concerning laser alloying and cladding presented in a second paper.

Clemencic, M.; Couturier, B.

2014-06-01

The nightly build system used so far by LHCb has been implemented as an extension of the system developed by CERN PH/SFT group (as presented at CHEP2010). Although this version has been working for many years, it has several limitations in terms of extensibility, management and ease of use, so that it was decided to develop a new version based on a continuous integration system. In this paper we describe a new implementation of the LHCb Nightly Build System based on the open source continuous integration system Jenkins and report on the experience of configuring a complex build workflow in Jenkins.

In 1967, Dan Janzen published "Why Mountain Passes Are Higher in the Tropics" in The American Naturalist. Janzen's seminal article has captured the attention of generations of biologists and continues to inspire theoretical and empirical work. The underlying assumptions and derived predictions are broadly synthetic and widely applicable. Consequently, Janzen's "seasonality hypothesis" has proven relevant to physiology, climate change, ecology, and evolution. To celebrate the fiftieth anniversary of this highly influential article, we highlight the past, present, and future of this work and include a unique historical perspective from Janzen himself.

Rodriguez, Saul; Sudarsky, Daniel

2018-03-01

In this work we consider the Higgs inflation scenario, but in contrast with past works, the present analysis is done in the context of a spontaneous collapse theory for the quantum state of the inflaton field. In particular, we will rely on a previously studied adaptation of the Continuous Spontaneous Localization model for the treatment of inflationary cosmology. We will show that with the introduction of the dynamical collapse hypothesis, some of the most serious problems of the Higgs inflation proposal can be resolved in a natural way.

Where Are the Academic Jobs? Interactive Exploration of Job Advertisements in Geospatial and Topical Space

NASA Astrophysics Data System (ADS)

Zoss, Angela M.; Conover, Michael; Börner, Katy

This paper details a methodology for capturing, analyzing, and communicating one specific type of real time data: advertisements of currently available academic jobs. The work was inspired by the American Recovery and Reinvestment Act of 2009 (ARRA) [2] that provides approximately 100 billion for education, creating a historic opportunity to create and save hundreds of thousands of jobs. Here, we discuss methodological challenges and practical problems when developing interactive visual interfaces to real time data streams such as job advertisements. Related work is discussed, preliminary solutions are presented, and future work is outlined. The presented approach should be valuable to deal with the enormous volume and complexity of social and behavioral data that evolve continuously in real time, and analyses of them need to be communicated to a broad audience of researchers, practitioners, clients, educators, and interested policymakers, as originally suggested by Hemmings and Wilkinson [1].

In Balint groups, (para)medical professionals explore difficult interactions with patients by means of case presentations and discussions. As the process of Balint group work is not well understood, this article investigates Balint group meetings by making use of Lacan's theory of the four discourses. Five Balint group case presentations and their subsequent group discussion were studied, resulting in the observation of five crucial aspects of Balint group work. First, Balint group participants brought puzzlement to the group, which is indicative of the structural impossibility Lacan situates at the basis of all discourse (1). As for the group discussion, we emphasize 'hysterization' as a crucial process in Balint group work (2), the supporting role of the discourse of the analyst (3) and the centrality of discourse interactions (4). Finally, the potential transformation of the initial puzzlement is discussed (5). We conclude by putting forth the uniqueness of Balint group work as well as the potential usefulness of our analysis as a framework for Balint group leaders and professionals in charge of continuing medical education. © The Author(s) 2016.

Salmon and Sagebrush: The Shoshone-Bannock Tribes Collaborative Approach to Adaptation Planning

The Shoshone-Bannock Tribes reside in the Upper Snake River Watershed in southeast Idaho. Their lives and culture are intertwined with the lands where they live; lands which continue to sustain the Tribes cultural, spiritual, dietary and economic needs. Climate change presents a new threat to the region requiring innovative approaches to prepare for changes as well as to protect the natural resources within the region. As a critical first step in building climate resilience, the Tribes worked with Adaptation International, the University of Washington's Climate Impacts Group (CIG) and the Oregon Climate Change Research Institute (OCCRI) to complete a collaborative climate change vulnerability assessment and adaptation planning process. This presentation provides an overview of collaborative process, shares the results of the project, and includes a 3-minute video presentation. The project started with the identification of 34 plant and animal species to focus the vulnerability assessment. OCCRI analyzed detailed downscaled climate projections for two key climate scenarios (RCP 4.5 and RCP 8.5) and timescales (2050s and 2080s). CIG then used NatureServe's Climate Change Vulnerability Index (CCVI) to develop initial relative vulnerability results for these species. A core team of Tribal staff members from various departments refined these results, drawing upon and integrating rich local and traditional knowledges of the natural environmental and cultural resources. The adaptation planning phase of the project continued in a similar collaborative manner with the project team identifying promising adaptation actions and working directly with Tribal staff to refine and customize these strategies. Tailoring the actions to the local context provides a framework for action that the Tribes can continue to build on in the future. By engaging in these efforts to identify vulnerable species and adaptation strategies and actions to minimize the negative effects of climate change, the Tribes have demonstrated their continued commitment to protecting their vital natural resources. The Tribes will continue to implement projects across landscapes in the near term and utilize the information co-produced as part of this project to develop long-term strategies and projects to build resilience.

Is work in education child's play? Understanding risks to educators arising from work organization and design of work spaces.

PubMed

Seifert, Ana María

2007-01-01

The educational sector exposes its primarily female work force to numerous psychosocial risk factors. At the request of the education workers', ergonomists developed a participatory research project in order to understand the determinants of the difficulties experienced by special education technicians. These technicians work with students presenting behavioral and learning difficulties as well as developmental and mental health problems. Eighteen technicians were interviewed and the work of seven technicians and two teachers was observed. Technicians prevent and manage crisis situations and help students acquire social skills. Coordination with teachers is made difficult by the fact that most technicians work part time, part year, and many technicians' work areas and classrooms are physically distant one from another. Most technicians change schools each year and must continually reconstruct work teams. Management strategies and poorly adapted working spaces can have important repercussions on coordination among educators and on technicians' capacity to help students and prevent aggressive behavior.

Young adult cancer survivors and work: a systematic review.

PubMed

Stone, Dawn S; Ganz, Patricia A; Pavlish, Carol; Robbins, Wendie A

2017-12-01

Sixty-three percent of cancer survivors continue to work, or return to work after treatment. Among this population, work ability and challenges encountered in the workplace by young adult cancer survivors have not been well established. The purposes of the study are to describe what is currently known about work-related issues for young adult cancer survivors diagnosed between ages 15 and 39, to identify gaps in the research literature, and to suggest interventions or improvements in work processes and occupational settings. A narrative review of articles using PubMed, CINAHL, and PsychInfo was conducted without date limitations. Search phrases included young adult cancer survivors, long-term cancer survivors, young adults affected by cancer, further combined with key terms employment, work, and occupationally active. Inclusion criteria for publications were young adult cancer survivors initially diagnosed between the ages of 15 and 39, data about work or employment was presented, and articles written in English. Twenty-three publications met the inclusion criteria. Work-related issues included the potential for reduced work productivity from cancer-changed physical and cognitive functional ability that affected income, and resulted in distress. Coping style, support systems, and changing perspectives about work and life in general were also influential on career decisions among young adult cancer survivors. More research is needed to study interventions to better manage health changes in young adult cancer survivors within the context of the workplace. Since financial hardship has been shown to be especially high among young cancer survivors, employment is essential to ensure payment of cancer-associated costs and continued medical care. While young adult cancer survivors may initially grapple with cancer-related physical and psychosocial changes that impact work productivity or influence choice of occupation, employment appears to enhance overall quality of life.

General practitioners' continuing education: a review of policies, strategies and effectiveness, and their implications for the future.

Smith, F; Singleton, A; Hilton, S

1998-01-01

BACKGROUND: The accreditation and provision of continuing education for general practitioners (GPs) is set to change with new proposals from the General Medical Council, the Government, and the Chief Medical Officer. AIM: To review the theories, policies, strategies, and effectiveness in GP continuing education in the past 10 years. METHOD: A systematic review of the literature by computerized and manual searches of relevant journals and books. RESULTS: Educational theory suggests that continuing education (CE) should be work-based and use the learner's experiences. Audit can play an important role in determining performance and needs assessment, but at present is largely a separate activity. Educational and professional support, such as through mentors or co-tutors, has been successfully piloted but awaits larger scale evaluation. Most accredited educational events are still the postgraduate centre lecture, and GP Tutors have a variable role in CE management and provision. Controlled trials of CE strategies suggest effectiveness is enhanced by personal feedback and work prompts. Qualitative studies have demonstrated that education plays only a small part in influencing doctors' behavior. CONCLUSION: Maintaining good clinical practice is on many stakeholders' agendas. A variety of methods may be effective in CE, and larger scale trials or evaluations are needed. PMID:10071406

Occupational stress in the multicultural workplace.

2011-08-01

Occupational stress is a well researched topic leading to the development of strong, viable models of workplace stress. However, there is a gap in the literature with respect to the applicability of this research to specific cultural groups, in particular those of immigrant status. The present paper reviews the extant literature regarding occupational stress from a multicultural perspective, evaluates the usefulness for existing models in the multicultural context, and discusses current issues with respect to increasing multiculturalism in the work environment. The authors conclude that workforce diversity is emerging as a pressing issue of organizational life and consequently, that future research needs to continue investigating whether current knowledge regarding workplace stress is fitting with the multicultural diversity of the present-day working population.

The historical analyses of Thomas McKeown attributed the modern rise in the world population from the 1700s to the present to broad economic and social changes rather than to targeted public health or medical interventions. His work generated considerable controversy in the 1970s and 1980s, and it continues to stimulate support, criticism, and commentary to the present day, in spite of his conclusions' having been largely discredited by subsequent research. The ongoing resonance of his work is due primarily to the importance of the question that underlay it: Are public health ends better served by targeted interventions or by broad-based efforts to redistribute the social, political, and economic resources that determine the health of populations?

The observational cross-sectional study conducted on a sample of 100 women workers who volunteered, outlines their cardio-respiratory and musculo-skeletal profile before, during and at end of work. In addition, information on their health status in general was collected in advance.Contrary to expectation, there was no significant change in respiratory function. However, the musculo-skeletal problems were found to be abundantly present with pain in 91% of the subjects. Region-wise mapping of pain revealed that postural pain in low back was present in 47% while in neck was 19%. Scapular muscles on the right side were involved in stabilizing shoulder, which never went overhead. On the contrary, left shoulder was raised as high (>90 degrees) in spinning action, while pulling thread. This muscle work involved trapezius, deltoid and triceps action concentrically in lifting and while coming to starting position slowly, eccentrically. There was no pause since the wheel continued to spin the thread continuously, unless a worker opted to stop the work. Accordingly, left wrist and hand were in holding contraction while the right wrist and hand holding the handle were also in a fixed position with wrist in flexion with supinated forearm. Though the overall job was light as per peak HR, there was pain due to fatigue and grip strength weakened by around 10%, at the end of the day's work. In conclusion, pain and fatigue were found to be the main problems for women in the spinning section of the small-scale industry under this study. Women have to take up dual responsibility of a full-time job as well as the domestic work. It was considered that ergonomic factors such as provision of a backrest and frequent rest periods could remediate the musculo-skeletal symptoms.

Continuing to work with a sterile thumb splint: A case report.

Nonoperative treatment of an injured ulnar collateral ligament of the thumb metacarpophalangeal (MCP) joint (skier's thumb without a Stener lesion) is managed by immobilization. A splint is applied on the radial side with the thumb in slight flexion to immobilize the MCP joint and allow motion in the interphalangeal joint. Thermoplastic splints are mainly used for daily activities with the advantage of custom fabrication for optimal comfort. To immobilize the thumb during surgical procedures performed by an orthopedic surgeon, splints made of sterilizable materials are needed but not yet available to our knowledge. We present the case of a 36-year-old orthopedic surgeon diagnosed with skier's thumb, and the development and application of a reusable, patient-specific (i.e., the orthopedic surgeon) splint to immobilize the thumb MCP joint in a sterile environment so the surgeon could continue working.

IT Operational Risk Measurement Model Based on Internal Loss Data of Banks

NASA Astrophysics Data System (ADS)

Hao, Xiaoling

Business operation of banks relies increasingly on information technology (IT) and the most important role of IT is to guarantee the operational continuity of business process. Therefore, IT Risk management efforts need to be seen from the perspective of operational continuity. Traditional IT risk studies focused on IT asset-based risk analysis and risk-matrix based qualitative risk evaluation. In practice, IT risk management practices of banking industry are still limited to the IT department and aren't integrated into business risk management, which causes the two departments to work in isolation. This paper presents an improved methodology for dealing with IT operational risk. It adopts quantitative measurement method, based on the internal business loss data about IT events, and uses Monte Carlo simulation to predict the potential losses. We establish the correlation between the IT resources and business processes to make sure risk management of IT and business can work synergistically.

This paper presents the verification of two partial indices proposed for the evaluation of continuous and impulse noise pollution in quarries. These indices, together with the sound power of machines index and the noise hazard index at the workstation, are components of the global index of assessment of noise hazard in the working environment of a quarry. This paper shows the results of acoustic tests carried out in an andesite quarry. Noise generated by machines and from performed blasting works was investigated. On the basis of acoustic measurements carried out in real conditions, the sound power levels of machines and the phenomenon of explosion were determined and, based on the results, three-dimensional models of acoustic noise propagation in the quarry were developed. To assess the degree of noise pollution in the area of the quarry, the continuous and impulse noise indices were used.

Objective The present study is intended to determine the organizational commitment of nurses and its relationship with demographic characteristics. Methods This study was a descriptive correlation (cross-sectional) study in January and February of 2016 on 126 nurses who held Bachelor of Science (B.Sc.) or Master of Science (M.Sc.) and at least one year of work experience in the Social Security Hospital of Khorramabad, selected using the census method. Data collection tools included a demographic characteristics form and Allen and Meyer questionnaire. Data analysis was performed using SPSS 20. Independent-samples t-test and one-way ANOVA were used to determine the relationship between organizational commitment and demographic characteristics. Results The majority of nurses had moderate organizational commitment, the highest score belonging to the continuance commitment (22.33%), and the lowest score belonging to the normative commitment (19.16%). Also, there was a significant correlation between the continuance commitment and work experience (p=0.001), the staff posts (p=0.01) and shifts (p=0.04). Conclusion Considering the moderate level of subjects’ organizational commitment in the present study, managers should take necessary measures to increase the attachment and organizational commitment of nurses and provide the ground for improving nursing services.

Self-calibration techniques of underwater gamma ray spectrometers.

In situ continuous monitoring of radioactivity in the water environment has many advantages compared to sampling and analysis techniques but a few shortcomings as well. Apart from the problems encountered in the assembly of the carrying autonomous systems, continuous operation some times alters the response function of the detectors. For example, the continuous operation of a photomultiplier tube results in a shift in the measured spectrum towards lower energies, making thus necessary the re-calibration of the detector. In this work, it is proved, that when measuring radioactivity in seawater, a photo peak around 50 keV will be always present in the measured spectrum. This peak is stable, depends only on the scattering rates of photons in seawater and, when it is detectable, can be used in conjunction with other peaks (40K and/or 208Tl) as a reference peak for the continuous calibration of the detector.

Monitoring patients with continuous-flow ventricular assist devices outside of the intensive care unit: novel challenges to bedside nursing.

Ventricular assist devices provide therapeutic options for patients with severe heart failure who have exhausted available medical therapies. With restoration of organ perfusion with ventricular assist devices, the heart failure resolves and quality of life and functional status improve. The current generation of continuous-flow devices present novel challenges to the clinical assessment of patients by substantially reducing or nearly eliminating any palpable pulse. Patients therefore generally have inadequate arterial pulsatility for most noninvasive monitoring devices such as pulse oximeters or automated blood pressure cuffs to work accurately. This article describes the function of continuous-flow devices and how this function affects common monitoring options, as well as how to clinically assess recipients of continuous-flow devices to promptly identify those whose condition may be deteriorating or who may be receiving inadequate perfusion.

Continuous Metabolic Monitoring Based on Multi-Analyte Biomarkers to Predict Exhaustion

PubMed Central

Kastellorizios, Michail; Burgess, Diane J.

2015-01-01

This work introduces the concept of multi-analyte biomarkers for continuous metabolic monitoring. The importance of using more than one marker lies in the ability to obtain a holistic understanding of the metabolism. This is showcased for the detection and prediction of exhaustion during intense physical exercise. The findings presented here indicate that when glucose and lactate changes over time are combined into multi-analyte biomarkers, their monitoring trends are more sensitive in the subcutaneous tissue, an implantation-friendly peripheral tissue, compared to the blood. This unexpected observation was confirmed in normal as well as type 1 diabetic rats. This study was designed to be of direct value to continuous monitoring biosensor research, where single analytes are typically monitored. These findings can be implemented in new multi-analyte continuous monitoring technologies for more accurate insulin dosing, as well as for exhaustion prediction studies based on objective data rather than the subject’s perception.

When a drip becomes a flood: Lessons learned from Target Corporation's first large-scale business disruption.

PubMed

Hirsch, Kimberly D; Strawser, Bryan E

Business continuity practitioners routinely determine which teams in their companies are critical and undertake extensive and rigorous planning processes. But what happens when a business is faced with an unanticipated long-term disruption that primarily affects non-critical teams? How can a company use the essential principles of business continuity and crisis management in order to respond? This paper explores a 2013 business disruption experienced by Target Corporation at one of its headquarters locations caused by a leak in the water line for an ice machine. Challenges encountered and reviewed include supporting non-critical teams, leadership of a multi-week business disruption and how remote work technologies have changed traditional continuity alternative workspace solution planning. Lessons learned from this activation are presented with implications for business continuity and emergency management planning that are applicable to any industry.

Non-conservative perturbations of homoclinic snaking scenarios

NASA Astrophysics Data System (ADS)

Knobloch, Jürgen; Vielitz, Martin

2016-01-01

Homoclinic snaking refers to the continuation of homoclinic orbits to an equilibrium E near a heteroclinic cycle connecting E and a periodic orbit P. Typically homoclinic snaking appears in one-parameter families of reversible, conservative systems. Here we discuss perturbations of this scenario which are both non-reversible and non-conservative. We treat this problem analytically in the spirit of the work [3]. The continuation of homoclinic orbits happens with respect to both the original continuation parameter μ and the perturbation parameter λ. The continuation curves are parametrised by the dwelling time L of the homoclinic orbit near P. It turns out that λ (L) tends to zero while the μ vs. L diagram displays isolas or criss-cross snaking curves in a neighbourhood of the original snakes-and-ladder structure. In the course of our studies we adapt both Fenichel coordinates near P and the analysis of Shilnikov problems near P to the present situation.

Cryptographic protocols are the backbone of our information society. This includes two-party protocols which offer protection against distrustful players. Such protocols can be built from a basic primitive called oblivious transfer. We present and experimentally demonstrate here a quantum protocol for oblivious transfer for optical continuous-variable systems, and prove its security in the noisy-storage model. This model allows us to establish security by sending more quantum signals than an attacker can reliably store during the protocol. The security proof is based on uncertainty relations which we derive for continuous-variable systems, that differ from the ones used in quantum key distribution. We experimentally demonstrate in a proof-of-principle experiment the proposed oblivious transfer protocol for various channel losses by using entangled two-mode squeezed states measured with balanced homodyne detection. Our work enables the implementation of arbitrary two-party quantum cryptographic protocols with continuous-variable communication systems.

Noncompliance of operators with work procedures is a recurrent problem. This human behavior has been said to be situational and studied by many different approaches (ergonomic and others), which consider the noncompliance with work procedures to be obvious and seek to analyze its causes as well as consequences. The object of the proposed method is to solve this problem by focusing on the performance of work procedures and ensuring improved performance on a continuous basis. This study has multiple results: (1) assessment of the work procedures' performance by a multicriteria approach; (2) the use of a continuous improvement approach as a framework for the sustainability of the assessment method of work procedures' performance; and (3) adaptation of the Stop-Card as a facilitator support for continuous improvement of work procedures. The proposed method emphasizes to put in value the inputs of continuous improvement of the work procedures in relation with the conventional approaches which adopt the obvious evidence of the noncompliance to the working procedures and seek to analyze the cause-effect relationships related to this unacceptable phenomenon, especially in strategic industry.

A comparative study of integrated pest management strategies based on impulsive control.

PubMed

Páez Chávez, Joseph; Jungmann, Dirk; Siegmund, Stefan

2018-12-01

The paper presents a comprehensive numerical study of mathematical models used to describe complex biological systems in the framework of integrated pest management. Our study considers two specific ecosystems that describe the application of control mechanisms based on pesticides and natural enemies, implemented in an impulsive and periodic manner, due to which the considered models belong to the class of impulsive differential equations. The present work proposes a numerical approach to study such type of models in detail, via the application of path-following (continuation) techniques for nonsmooth dynamical systems, via the novel continuation platform COCO (Dankowicz and Schilder). In this way, a detailed study focusing on the influence of selected system parameters on the effectiveness of the pest control scheme is carried out for both ecological scenarios. Furthermore, a comparative study is presented, with special emphasis on the mechanisms upon which a pest outbreak can occur in the considered ecosystems. Our study reveals that such outbreaks are determined by the presence of a branching point found during the continuation analysis. The numerical investigation concludes with an in-depth study of the state-dependent pesticide mortality considered in one of the ecological scenarios.

Intravenous drugs active via gamma-aminobutyric acid receptors to produce memory impairment during conscious sedation. Memory function was assessed using event-related potentials (ERPs) while drug was present. The continuous recognition task measured recognition of photographs from working (6 s) and long-term (27 s) memory while ERPs were recorded from Cz (familiarity recognition) and Pz electrodes (recollection recognition). Volunteer participants received sequential doses of one of placebo (n = 11), 0.45 and 0.9 microg/ml propofol (n = 10), 20 and 40 ng/ml midazolam (n = 12), 1.5 and 3 microg/ml thiopental (n = 11), or 0.25 and 0.4 ng/ml dexmedetomidine (n = 11). End-of-day yes/no recognition 225 min after the end of drug infusion tested memory retention of pictures encoded on the continuous recognition tasks. Active drugs increased reaction times and impaired memory on the continuous recognition task equally, except for a greater effect of midazolam (P < 0.04). Forgetting from continuous recognition tasks to end of day was similar for all drugs (P = 0.40), greater than placebo (P < 0.001). Propofol and midazolam decreased the area between first presentation (new) and recognized (old, 27 s later) ERP waveforms from long-term memory for familiarity (P = 0.03) and possibly for recollection processes (P = 0.12). Propofol shifted ERP amplitudes to smaller voltages (P < 0.002). Dexmedetomidine may have impaired familiarity more than recollection processes (P = 0.10). Thiopental had no effect on ERPs. Propofol and midazolam impaired recognition ERPs from long-term memory but not working memory. ERP measures of memory revealed different pathways to end-of-day memory loss as early as 27 s after encoding.

Kalkowsky, Bernhard; Kampmann, Bernhard

2006-07-01

As the percentage of shifts in hot working conditions in German Coal mines had increased to more than 50% during the last decade, a study was carried out to record the physiological strain of miners. Thirty-eight miners participated during 125 shifts. Heart rate and rectal temperature were measured continuously. Sweat losses as well as food and fluid uptake were estimated from measurements before and after shifts. During all shifts mean heart rates resulted in 102.8 min(-1), mean rectal temperature was 37.7 degrees C. Mean sweat loss per shift was 3,436 g; mean sweat rates resulted in 494 g/h. Rehydration during the shift at high climatic stress decreased to about 60% of sweat losses. In order to state the organizational frame of work at hot working places in German coal mines, the main features of regulations of work at hot working places are presented.

Effects of workplace bullying on how women work.

2010-11-01

Work is central to well-being but working is problematic when people experience workplace bullying, which includes psychological, physical, and sexual abuse or harassment. The purpose of the present grounded theory study was to extend current understanding, from the perspective of women, of how workplace bullying affects their work and how they engage in the workforce. The study was conducted in eastern Canada with 36 English-speaking women who had been bullied in the workplace. They reported mainly psychological bullying. The central problem for women is they cannot continue working as they had before the workplace bullying. The authors named a four-stage process of how women address this problem as "Doing Work Differently." The four stages are Being Conciliatory, Reconsidering, Reducing Interference, and Redeveloping Balance. The process is influenced by women's support systems, the effects on their health, and financial circumstances. There are implications for public education, workplace policies, and health care workers.

Provider connectedness and communication patterns: extending continuity of care in the context of the circle of care

PubMed Central

2013-01-01

Background Continuity is an important aspect of quality of care, especially for complex patients in the community. We explored provider perceptions of continuity through a system’s lens. The circle of care was used as the system. Methods Soft systems methodology was used to understand and improve continuity for end of life patients in two communities. Participants: Physicians, nurses, pharmacists in two communities in British Columbia, involved in end of life care. Two debates/discussion groups were completed after the interviews and initial analysis to confirm findings. Interview recordings were qualitatively analyzed to extract components and enablers of continuity. Results 32 provider interviews were completed. Findings from this study support the three types of continuity described by Haggerty and Reid (information, management, and relationship continuity). This work extends their model by adding features of the circle of care that influence and enable continuity: Provider Connectedness the sense of knowing and trust between providers who share care of a patient; a set of ten communication patterns that are used to support continuity across the circle of care; and environmental factors outside the circle that can indirectly influence continuity. Conclusions We present an extended model of continuity of care. The components in the model can support health planners consider how health care is organized to promote continuity and by researchers when considering future continuity research. PMID:23941179

in Australia, models of maternity care that offer women continuity of care with a known midwife have been promoted. Little is known about the intentions of the future midwifery workforce to work in such models. This study aimed to explore midwifery students' views and experiences of caseload midwifery and their work intentions in relation to the caseload model following graduation. cross-sectional survey. Victoria, Australia. 129 midwifery students representing all midwifery course pathways (Post Graduate Diploma, Bachelor of Midwifery, Bachelor of Nursing/Bachelor of Midwifery) in Victoria. midwifery students from all course pathways considered that continuity of care is important to women and indicated that exposure to continuity models during their course was very positive. Two-thirds of the students (67%) considered that the continuity experiences made them want to work in a caseload model; only 5% reported that their experiences had discouraged them from continuity of care work in the future. Most wanted a period of consolidation to gain experience as a midwife prior to commencing in the caseload model. Perceived barriers to caseload work were being on-call, and challenges in regard to work/life balance and family commitments. midwifery students in this study were very positive about caseload midwifery and most would consider working in caseload after a period of consolidation. Continuity of care experiences during students' midwifery education programmes appeared to provide students with insight and understanding of continuity of care for both women and midwives. Further research should explore what factors influence students' future midwifery work, whether or not their plans are fulfilled, and whether or not the caseload midwifery workforce can be sustained.

Concurrent generation of multivariate mixed data with variables of dissimilar types.

PubMed

Amatya, Anup; Demirtas, Hakan

2016-01-01

Data sets originating from wide range of research studies are composed of multiple variables that are correlated and of dissimilar types, primarily of count, binary/ordinal and continuous attributes. The present paper builds on the previous works on multivariate data generation and develops a framework for generating multivariate mixed data with a pre-specified correlation matrix. The generated data consist of components that are marginally count, binary, ordinal and continuous, where the count and continuous variables follow the generalized Poisson and normal distributions, respectively. The use of the generalized Poisson distribution provides a flexible mechanism which allows under- and over-dispersed count variables generally encountered in practice. A step-by-step algorithm is provided and its performance is evaluated using simulated and real-data scenarios.

“I WILL SURVIVE” A Construct Validation Study on the Measurement of Sustainable Employability Using Different Age Conceptualizations

PubMed Central

Le Blanc, Pascale M.; Van der Heijden, Beatrice I. J. M.; Van Vuuren, Tinka

2017-01-01

Though the importance of sustainable employability throughout people's working life is undisputed, up till now only one attempt for a conceptual definition has been made (van der Klink et al., 2016). Following the suggestions to further refine and improve this definition recently put forward by Fleuren et al. (2016), we propose an approach to sustainable employability that is based on the Ability-Motivation-Opportunity (AMO) framework, and incorporates three indicators: the ability, the motivation, and the opportunity to continue working, respectively. As sustainable employability is considered to be an important aspect of successful aging at work, this study used four different conceptualizations of aging at work to set up convergent and divergent validity of our operationalization of sustainable employability: calendar age, organizational age (job and organizational tenure), functional age (work ability), and life-span age (partner and children). We formulated several hypotheses that were tested by analyzing data from an online survey among 180 employees from Dutch public service organizations who filled out a questionnaire on different age concepts, and their ability, motivation, and opportunity to continue working. Multiple regression analyses were performed, and results showed that the four conceptualizations of aging were differently related to the three indicators of sustainable employability. Life-span age, in terms of having children, had the strongest negative relationship with the ability to continue working, organizational age (i.e., organizational tenure) had the strongest negative relationship with the motivation to continue working, and functional age had the strongest negative relationship with the opportunity to continue working. Moreover, functional age was significantly negatively related to the other two indicators of sustainable employability too, while life-span age appeared to enhance the ability and motivation to continue working (in terms of having children) and the perceived opportunity to continue working (in terms of having a partner). Calendar age was only important for the opportunity to continue working and appeared to have a negative association with this outcome variable. These results lend support to our proposed operationalization of sustainable employability by showing that the three indicators are differently related to different age conceptualizations thus expanding previous research on the conceptualization of sustainable employability.

Occupational exposure to municipal solid wastes and development of toxic neuropathies: possible role of nutrient supplementation, complementary and alternative medicines in chemoprevention.

PubMed

Ekor, Martins; Odewabi, Adesina O

2014-09-01

Achieving effective municipal solid waste (MSW) management remains a major challenge and waste generation and accumulation continue to constitute important environmental and public health concern, particularly in most developing countries. Although the general population is at risk of adverse health consequences and hazards associated with exposure to MSW, the waste management workers (WMWs) are the most vulnerable because of their direct involvement in the disposal of waste, with increasing evidence of work-related health and safety risks among these individuals. Among the numerous work-related health hazards prevalent in WMWs, development of toxic neuropathies following chronic occupational exposure remains poorly recognized. However, the risk or predisposition to toxic neuropathies is becoming evident considering the increasing recognition of large amount of neurotoxic heavy metals and hazardous industrial materials present in MSW in most parts of the world. The present review seeks to draw attention to the continuous vulnerability of the WMWs to developing toxic neuropathies. This is aimed at facilitating conscious efforts by relevant governmental and nongovernmental agencies towards promoting risk reduction and ensuring adequate protection against possible toxic polyneuropathies associated with occupational exposure to solid wastes. While continuous education of the WMWs on the need for adequate compliance to safety regulations and practice remains sacrosanct towards achieving significant reduction in toxic neuropathies and related adverse health consequences of waste handling, it is also our intention in this review to underscore the possible relevance of nutrient supplementation and alternative medicines in chemoprevention.

Flood forecasting undergoes a constant evolution, becoming more and more demanding about the models used for hydrologic simulations. The advantages of developing distributed or semi-distributed models have currently been made clear. Now the importance of using continuous distributed modeling emerges. A proper schematization of the infiltration process is vital to these types of models. Many popular infiltration schemes, reliable and easy to implement, are too simplistic for the development of continuous hydrologic models. On the other hand, the unavailability of detailed and descriptive information on soil properties often limits the implementation of complete infiltration schemes. In this work, a combination between the Soil Conservation Service Curve Number method (SCS-CN) and a method derived from Horton equation is proposed in order to overcome the inherent limits of the two schemes. The SCS-CN method is easily applicable on large areas, but has structural limitations. The Horton-like methods present parameters that, though measurable to a point, are difficult to achieve a reliable estimate at catchment scale. The objective of this work is to overcome these limits by proposing a calibration procedure which maintains the large applicability of the SCS-CN method as well as the continuous description of the infiltration process given by the Horton's equation suitably modified. The estimation of the parameters of the modified Horton method is carried out using a formal analogy with the SCS-CN method under specific conditions. Some applications, at catchment scale within a distributed model, are presented.

To identify the combination of variables that explain nurses' continuation intention in the UK National Health Service. This alternative arena has permitted the replication of a private sector Australian study. This study provides understanding about the issues that affect nurse retention in a sector where employee attrition is a key challenge, further exacerbated by an ageing workforce. A quantitative study based on a self-completion survey questionnaire completed in 2010. Nurses employed in two UK National Health Service Foundation Trusts were surveyed and assessed using seven work-related constructs and various demographics including age generation. Through correlation, multiple regression and stepwise regression analysis, the potential combined effect of various explanatory variables on continuation intention was assessed, across the entire nursing cohort and in three age-generation groups. Three variables act in combination to explain continuation intention: work-family conflict, work attachment and importance of work to the individual. This combination of significant explanatory variables was consistent across the three generations of nursing employee. Work attachment was identified as the strongest marginal predictor of continuation intention. Work orientation has a greater impact on continuation intention compared with employer-directed interventions such as leader-member exchange, teamwork and autonomy. UK nurses are homogeneous across the three age-generations regarding explanation of continuation intention, with the significant explanatory measures being recognizably narrower in their focus and more greatly concentrated on the individual. This suggests that differentiated approaches to retention should perhaps not be pursued in this sectoral context. © 2014 John Wiley & Sons Ltd.

Experiments were performed using detonating LX-17 (92.5% TATB, 7.5% Kel-f by weight) charges with various width transverse air gaps both with and without manganin peizoresistive in-situ gauges present. The experiments, performed with 25 mm diameter by 25 mm long LX-17 pellets with the transverse air gap in between, showed that transverse gaps up to about 3 mm could be present without causing the detonation wave to fail to continue as a detonation. A JWL++/Tarantula code was utilized to model the results and compare with the in-situ gauge records with reasonable agreement to the experimental data. This work will present the experimental details as well as comparison to the model results. This work performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344.

Frair, L.

1981-01-01

Results from continued research on selected parameters to minimize community annoyance from airport noise are reported. First, a review of the initial work on this problem is presented. Then the research focus is expanded by considering multiobjective optimization approaches for this problem. A multiobjective optimization algorithm review from the open literature is presented. This is followed by the multiobjective mathematical formulation for the problem of interest. A discussion of the appropriate solution algorithm for the multiobjective formulation is conducted. Alternate formulations and associated solution algorithms are discussed and evaluated for this airport noise problem. Selected solution algorithms that have been implemented are then used to produce computational results for example airports. These computations involved finding the optimal operating scenario for a moderate size airport and a series of sensitivity analyses for a smaller example airport.

Diffusion theory of decision making in continuous report.

PubMed

Smith, Philip L

2016-07-01

I present a diffusion model for decision making in continuous report tasks, in which a continuous, circularly distributed, stimulus attribute in working memory is matched to a representation of the attribute in the stimulus display. Memory retrieval is modeled as a 2-dimensional diffusion process with vector-valued drift on a disk, whose bounding circle represents the decision criterion. The direction and magnitude of the drift vector describe the identity of the stimulus and the quality of its representation in memory, respectively. The point at which the diffusion exits the disk determines the reported value of the attribute and the time to exit the disk determines the decision time. Expressions for the joint distribution of decision times and report outcomes are obtained by means of the Girsanov change-of-measure theorem, which allows the properties of the nonzero-drift diffusion process to be characterized as a function of a Euclidian-distance Bessel process. Predicted report precision is equal to the product of the decision criterion and the drift magnitude and follows a von Mises distribution, in agreement with the treatment of precision in the working memory literature. Trial-to-trial variability in criterion and drift rate leads, respectively, to direct and inverse relationships between report accuracy and decision times, in agreement with, and generalizing, the standard diffusion model of 2-choice decisions. The 2-dimensional model provides a process account of working memory precision and its relationship with the diffusion model, and a new way to investigate the properties of working memory, via the distributions of decision times.

2011-10-01

The present study investigates the dental work in terms of time distribution and mechanical exposure in value-adding work (VAW) and non-VAW. Further rationalisation of dental work would typically involve an increase in the proportion of VAW. Information on mechanical exposure within the classes of VAW and non-VAW may be used to predict possible implications of rationalisation. Sixteen dentists were investigated. Using a data logger, postures and movements were continuously recorded for each subject during the 4 h of work, which included the 45 min of video recording. Time distribution and mechanical exposure for the six different work activities identified were evaluated from the video recordings, using a loss analysis technique. VAW, which comprised 54% of the total working time, generally implied significantly more constrained mechanical exposures as compared with non-VAW. The results suggest that future rationalisation of dental work, involving a reduction of non-VAW, may increase the risk of developing musculoskeletal disorders. Statement of Relevance: The present study illustrates the potential effects of rationalisation on biomechanical exposures for dentists. The results highlight the significance of integrating ergonomic issues into the rationalisation process in dentistry in addition to ordinary workstation and tool design improvements performed by ergonomists.

Heider balance in human networks

NASA Astrophysics Data System (ADS)

Gawroński, P.; Kułakowski, K.

2005-07-01

Recently, a continuous dynamics was proposed to simulate dynamics of interpersonal relations in a society represented by a fully connected graph. The final state of such a society was found to be identical with the so-called Heider balance (HB), where the society is divided into two mutually hostile groups. In the continuous model, a polarization of opinions was found in HB. Here we demonstrate that the polarization occurs also in Barabási-Albert networks, where the Heider balance is not necessarily present. In the second part of this work we demonstrate the results of our formalism, when applied to reference examples: the Southern women and the Zachary club.

Continuous Modeling of Calcium Transport Through Biological Membranes

Jasielec, J. J.; Filipek, R.; Szyszkiewicz, K.; Sokalski, T.; Lewenstam, A.

2016-08-01

In this work an approach to the modeling of the biological membranes where a membrane is treated as a continuous medium is presented. The Nernst-Planck-Poisson model including Poisson equation for electric potential is used to describe transport of ions in the mitochondrial membrane—the interface which joins mitochondrial matrix with cellular cytosis. The transport of calcium ions is considered. Concentration of calcium inside the mitochondrion is not known accurately because different analytical methods give dramatically different results. We explain mathematically these differences assuming the complexing reaction inside mitochondrion and the existence of the calcium set-point (concentration of calcium in cytosis below which calcium stops entering the mitochondrion).

Combining the surface dielectric barrier discharges generated in contact with water based electrolytes, as the discharge electrodes, we have designed a new type of surface electric discharge, generating thin layers of plasma which propagate along the treated polymer surfaces. The technique was aimed to achieve uniform atmospheric pressure plasma treatment of polymeric tubes and other hollow bodies. The results presented in this work show the possibility of such system to treat outer surface of polymer materials in a continuous mode. The technical details of experimental setup are discussed as well as results of treatment of polyethylene tubes are shown.

2015-08-24

Considering a practical continuous variable quantum key distribution(CVQKD) system, synchronization is of significant importance as it is hardly possible to extract secret keys from unsynchronized strings. In this paper, we proposed a high performance frame synchronization method for CVQKD systems which is capable to operate under low signal-to-noise(SNR) ratios and is compatible with random phase shift induced by quantum channel. A practical implementation of this method with low complexity is presented and its performance is analysed. By adjusting the length of synchronization frame, this method can work well with large range of SNR values which paves the way for longer distance CVQKD.

The gift of employee dissatisfaction.

Edge, Roberta M

2002-01-01

Through an employee survey administered at Kaweah Delta Health Care District (KDHCD) in Visalia, Calif., several sources of dissatisfaction were noted, including communication, equipment, staffing and rapid growth. Perceiving no real movement toward resolving these issues, employees vented their frustrations to administration. As director of imaging services, I enlisted the help of two inside consultants, KDHCD's director of education and the director of the Employee Assistance Program (EAP). We initiated a process that is ongoing, to move the department toward working together as a team to solve problems within their control. We three directors decided to work with a leadership group to: assess the history of the department clarify the current reality create a vision of the future learn the Covey Habit 4, "Think Win-Win" capture agreements that lead staff and managers to work in self-motivated, self-directed work teams have the director of education present the work to the staff at large, and encourage the leadership team to continue to learn tools that would help the group to improve. The two inside consultants held a series of training meetings with the leadership group of 15, which included a staff member from each modality, site and support service. Participation was optional, and all who were asked agreed to participate. The meetings were held weekly for four weeks for two hours before regular work hours. At the conclusion of the training, the group agreed to continue to meet weekly. After the first four meetings, a summary of the training was presented at a meeting of the full imaging staff plus the vice president of professional services at KDHCD. Through this program, imaging services staff members at KDHCD have achieved an increased sense of cohesion in the group, learned that we have control over some things and not others, and are learning to hold each other accountable with kindness. We are giving each other the benefit of the doubt. We have not achieved perfection, however we have renewed hope for a brighter future.

The infantile psychic trauma from us to Freud: pure trauma, retroactivity and reconstruction.

PubMed

Baranger, M; Baranger, W; Mom, J M

1988-01-01

In the works of Freud, the concept of childhood psychic trauma evolves in the direction of increasing complexity. The authors maintain that this expansion corresponds to a new conception of retroactive temporality (Nachträglich), which is precisely the one we use in the analytic process of reconstruction and historicization from the present toward the past. We are thus led to differentiate the extreme form of the unassimilable 'pure' Trauma, nearly pure death drive, from the retroactively historicized forms which are reintegrated into the continuity of a vital flow of time that we 'invent' in analytic work.

2010-05-12

Development work to implement a new welding system for a Firing Set is presented. The new system is significant because it represents the first use of fiber laser welding technology at the KCP. The work used Six-Sigma tools for weld characterization and to define process performance. Determinations of workable weld parameters and comparison to existing equipment were completed. Replication of existing waveforms was done utilizing an Arbitrary Pulse Generator (APG), which was used to modulate the fiber laser’s exclusive continuous wave (CW) output. Fiber laser weld process capability for a Firing Set is demonstrated.

In 1977 McDonnell Douglas Astronautics Company began a project on using fiber optic sensors to support the Delta Rocket program. This resulted in a series of fiber sensors to support the measurement of rotation, acoustics, vibration, strain, and temperature for a variety of applications and early work on fiber optic smart structures. The work on fiber optic smart structures transitioned in part to Blue Road Research in 1993 and continued in 2006 to the present at Columbia Gorge Research. This paper summarizes some of the efforts made by these companies to implement fiber optic smart structures over this forty year period.

How does running memory span work?

PubMed

Bunting, Michael; Cowan, Nelson; Saults, J Scott

2006-10-01

In running memory span, a list ends unpredictably, and the last few items are to be recalled. This task is of increasing importance in recent research. We argue that there are two very different strategies for performing running span tasks: a low-effort strategy in which items are passively held until the list ends, when retrieval into a capacity-limited store takes place; and a higher-effort strategy in which working memory is continually updated using rehearsal processes during the list presentation. In two experiments, we examine the roles of these two strategies and the consequences of two types of interference.

Detection and Alert of muscle fatigue considering a Surface Electromyography Chaotic Model

2011-03-01

This work propose a detection and alert algorithm for muscle fatigue in paraplegic patients undergoing electro-therapy sessions. The procedure is based on a mathematical chaotic model emulating physiological signals and Continuous Wavelet Transform (CWT). The chaotic model developed is based on a logistic map that provides suitable data accomplishing some physiological signal class patterns. The CWT was applied to signals generated by the model and the resulting vector was obtained through Total Wavelet Entropy (TWE). In this sense, the presented work propose a viable and practical alert and detection algorithm for muscle fatigue.

Nanopillar based electrochemical biosensor for monitoring microfluidic based cell culture

NASA Astrophysics Data System (ADS)

Gangadharan, Rajan

In-vitro assays using cultured cells have been widely performed for studying many aspects of cell biology and cell physiology. These assays also form the basis of cell based sensing. Presently, analysis procedures on cell cultures are done using techniques that are not integrated with the cell culture system. This approach makes continuous and real-time in-vitro measurements difficult. It is well known that the availability of continuous online measurements for extended periods of time will help provide a better understanding and will give better insight into cell physiological events. With this motivation we developed a highly sensitive, selective and stable microfluidic electrochemical glucose biosensor to make continuous glucose measurements in cell culture media. The performance of the microfluidic biosensor was enhanced by adding 3D nanopillars to the electrode surfaces. The microfluidic glucose biosensor consisted of three electrodes---Enzyme electrode, Working electrode, and Counter electrode. All these electrodes were enhanced with nanopillars and were optimized in their respective own ways to obtain an effective and stable biosensing device in cell culture media. For example, the 'Enzyme electrode' was optimized for enzyme immobilization via either a polypyrrole-based or a self-assembled-monolayer-based immobilization method, and the 'Working electrode' was modified with Prussian Blue or electropolymerized Neutral Red to reduce the working potential and also the interference from other interacting electro-active species. The complete microfluidic biosensor was tested for its ability to monitor glucose concentration changes in cell culture media. The significance of this work is multifold. First, the developed device may find applications in continuous and real-time measurements of glucose concentrations in in-vitro cell cultures. Second, the development of a microfluidic biosensor will bring technical know-how toward constructing continuous glucose monitoring devices. Third, the methods used to develop 3D electrodes incorporated with nanopillars can be used for other applications such as neural probes, fuel cells, solar cells etc., and finally, the knowledge obtained from the immobilization of enzymes onto nanostructures sheds some new insight into nanomaterial/biomolecule interactions.

A lightweight ambient air-cooling unit for use in hazardous environments.

Chen, Y T; Constable, S H; Bomalaski, S H

1997-01-01

Recent research demonstrated (a) the effectiveness of intermittent conditioned air cooling during rest breaks to significantly reduce cumulative heat storage and (b) that longer work sessions were possible for individuals wearing chemical defense ensembles. To further advance this concept, a strategy for implementing continuous air cooling was conceived; ambient air cooling was added during work cycles and conditioned air cooling was delivered during rest periods. A compact battery-powered beltpack cooling unit (3.9 kg) designed and made at the U.S. Air Force Armstrong Laboratory was used to deliver 5.7 L/sec filtered ambient air during work cycles: 4.7 L/sec to the body and 1 L/sec to the face. Five experimental cycles were conducted in a thermally controlled chamber under warm conditions (32 degrees C, 40% relative humidity) with (1) no cooling-intermittent work, (2) intermittent cooling, (3) continuous cooling during intermittent exercise, and (4) no cooling-continuous work and (5) ambient air cooling during continuous exercise. Intermittent, conditioned, and continuous air cooling resulted in significant reductions in rectal temperature, mean skin temperature, and heart rate as compared with the no-cooling trials. The continuous air-cooling trial significantly improved thermal comfort and sweat evaporation. Results suggest that ambient air delivered during work cycles by a lightweight portable unit (in conjunction with conditioned air delivered during rest periods), can definitely improve personal comfort, reduce skin temperature, and decrease the cumulative fatigue common to repeated work/rest cycles in selected military and industrial applications in which individuals work in chemical defense ensembles.

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also evaluated. Participants were 144 students initially identified as having a math difficulty (MD) or no learning difficulty according to low achievement criteria in the spring of Grade 3 or Grade 4. Students were reassessed 2 years later. For both measure types, a similar proportion of students changed whether assessed categorically or continuously. However, categorical change was heavily dependent on distance from the cut point and so more common for MD, who started closer to the cut point; reliable change index change was more similar across groups. There were few differences with regard to severity level of MD on continuous metrics or in terms of prediction. Final math performance on a broad computation measure was predicted by behavioral inattention and working memory while considering initial performance; for a specific fluency measure, working memory was not uniquely related, and behavioral inattention more variably related to final performance, again while considering initial performance.

Theoretical study of the characteristics of a continuous wave iron-doped ZnSe laser

2018-03-01

A theoretical model describing the dynamic process of a continuous-wave Fe2+:ZnSe laser is presented. The influence of some of the operating parameters on the output characteristics of an Fe2+:ZnSe laser is studied in detail. The results indicate that the temperature rise of the Fe2+:ZnSe crystal is significant with the use of a high power pump laser, especially for a high doped concentration of crystal. The optimal crystal length increases with decreasing the doped concentration of crystal, so an Fe2+:ZnSe crystal with simultaneous doping during growth is an attractive choice, which usually has a low doped concentration and long length. The laser pumping threshold is almost stable at low temperatures, but increases exponentially with a working temperature in the range of 180 K to room temperature. The main reason for this phenomenon is the short upper level lifetime and serious thermal temperature rise when the working temperature is higher than 180 K. The calculated optimum output mirror transmittance is about 35% and the performance of a continuous-wave Fe2+:ZnSe laser is more efficient at a lower operating temperature.

Staff nurse commitment, work relationships, and turnover intentions: a latent profile analysis.

PubMed

Gellatly, Ian R; Cowden, Tracy L; Cummings, Greta G

2014-01-01

The three-component model of organization commitment has typically been studied using a variable-centered rather than a person-centered approach, preventing a more complete understanding of how these forms of commitment are felt and expressed as a whole. Latent profile analysis was used to identify qualitatively distinct categories or profiles of staff nurses' commitment. Then, associations of the profiles with perceived work unit relations and turnover intentions were examined. Three hundred thirty-six registered nurses provided data on affective, normative, and continuance commitment, perceived work unit relations, and turnover intentions. Latent profile analysis of the nurses' commitment scores revealed six distinct profile groups. Work unit relations and turnover intentions were compared in the six profile-defined groups. Staff nurses with profiles characterized by high affective commitment and/or high normative commitment in relation to other components experienced stronger work unit relations and reported lower turnover intentions. Profiles characterized by high continuance commitment relative to other components or by low overall commitment experienced poorer work unit relations, and the turnover risk was higher. High continuance commitment in combination with high affective and normative commitment was experienced differently than high continuance commitment in combination with low affective and normative commitment. Healthcare organizations often foster commitment by using continuance commitment-enhancing strategies (e.g., offer high salaries and attractive benefits) that may inadvertently introduce behavioral risk. This work suggests the importance of changing the context in which continuance commitment occurs by strengthening the other two components.

Petrén, V; Levin, G; Chohan, T; Preber, H; Candell, A; Bergström, J

2005-08-01

The present study examined factors for workplace improvement and continuing professional development (CPD) for Swedish dental hygienists. Seventy-one per cent of 577 randomly selected members of Sweden's Dental Hygienist Association responded to a questionnaire. The chi-square test, Spearman's rank correlation, and multiple stepwise logistic regression modelling were used in the statistical analysis. The results showed that dental hygienists having more than 10 sick days annually and with a strong commitment to their work increased the preference for workplace improvements, such as peer recognition of dental hygienists' professional qualifications, clinical process quality, and time for reading research articles and participating in projects. In addition, dental hygienists in the 41-52 age group were associated with workplace improvements. This is in contrast to the factors that decreased preferences for workplace improvements: clear work roles, a 1-year training programme, a male clinic manager, and working in the private sector. Practicing dental hygiene in the public sector and lifestyle factors were the most influential determinants for a strong interest in CPD. Workplaces should observe people that are obviously committed to their work, those with many sick days, and those in a specific age group, as they indicate different preferences for workplace improvements. CPD seems to be a lower priority than workplace improvements for Swedish dental hygienists.

Recent progress in continuous and semi-continuous processing of solid oral dosage forms: a review.

Continuous processing is an innovative production concept well known and successfully used in other industries for many years. The modern pharmaceutical industry is facing the challenge of transition from a traditional manufacturing approach based on batch-wise production to a continuous manufacturing model. The aim of this article is to present technological progress in manufacturing based on continuous and semi-continuous processing of the solid oral dosage forms. Single unit processes possessing an alternative processing pathway to batch-wise technology or, with some modification, an altered approach that may run continuously, and are thus able to seamlessly switch to continuous manufacturing are briefly presented. Furthermore, the concept of semi-continuous processing is discussed. Subsequently, more sophisticated production systems created by coupling single unit processes and comprising all the steps of production, from powder to final dosage form, were reviewed. Finally, attempts of end-to-end production approach, meaning the linking of continuous synthesis of API from intermediates with the production of final dosage form, are described. There are a growing number of scientific articles showing an increasing interest in changing the approach to the production of pharmaceuticals in recent years. Numerous scientific publications are a source of information on the progress of knowledge and achievements of continuous processing. These works often deal with issues of how to modify or replace the unit processes in order to enable seamlessly switching them into continuous processing. A growing number of research papers concentrate on integrated continuous manufacturing lines in which the production concept of "from powder to tablet" is realized. Four main domains are under investigation: influence of process parameters on intermediates or final dosage forms properties, implementation of process analytical tools, control-managing system responsible for keeping continuous materials flow through the whole manufacturing process and the development of new computational methods to assess or simulate these new manufacturing techniques. The attempt to connect the primary and secondary production steps proves that development of continuously operating lines is possible. A mind-set change is needed to be able to face, and fully assess, the advantages and disadvantages of switching from batch to continuous mode production.

The mu opioid receptor (MOR) is critical in mediating morphine analgesia. However, prolonged exposure to morphine induces adaptive changes in this receptor leading to the development of tolerance and addiction. In the present work we have studied whether the continuous administration of morphine induces changes in MOR protein levels, its pharmacological profile, and MOR-mediated G-protein activation in the striosomal compartment of the rat CPu, by using immunohistochemistry and receptor and DAMGO-stimulated [35S]GTPγS autoradiography. MOR immunoreactivity, agonist binding density and its coupling to G proteins are up-regulated in the striosomes by continuous morphine treatment in the absence of changes in enkephalin and dynorphin mRNA levels. In addition, co-treatment of morphine with the dopamine D4 receptor (D4R) agonist PD168,077 fully counteracts these adaptive changes in MOR, in spite of the fact that continuous PD168,077 treatment increases the [3H]DAMGO Bmax values to the same degree as seen after continuous morphine treatment. Thus, in spite of the fact that both receptors can be coupled to Gi/0 protein, the present results give support for the existence of antagonistic functional D4R-MOR receptor-receptor interactions in the adaptive changes occurring in MOR of striosomes on continuous administration of morphine.

The aim of this study was to obtain a predictive model able to perform an early detection of central segregation severity in continuous cast steel slabs. Segregation in steel cast products is an internal defect that can be very harmful when slabs are rolled in heavy plate mills. In this research work, the central segregation was studied with success using the data mining methodology based on multivariate adaptive regression splines (MARS) technique. For this purpose, the most important physical-chemical parameters are considered. The results of the present study are two-fold. In the first place, the significance of each physical-chemical variable on the segregation is presented through the model. Second, a model for forecasting segregation is obtained. Regression with optimal hyperparameters was performed and coefficients of determination equal to 0.93 for continuity factor estimation and 0.95 for average width were obtained when the MARS technique was applied to the experimental dataset, respectively. The agreement between experimental data and the model confirmed the good performance of the latter.

The design work for 2nd harmonic 95 GHz, 50 kW gyrotron based on continuous operation copper solenoid is presented. Thermionic magnetron injection gun specifications were calculated according to the linear trade off equation, and simulated with CST program. Numerical code is used for cavity design using the non-uniform string equation as well as particle motion in the “cold” cavity field. The mode TE02 with low Ohmic losses in the cavity walls was chosen as the operating mode. The Solenoid is designed to induce magnetic field of 1.8 T over a length of 40 mm in the interaction region with homogeneitymore » of ±0.34%. The solenoid has six concentric cylindrical segments (and two correction segments) of copper foil windings separated by water channels for cooling. The predicted temperature in continuous operation is below 93 °C. The parameters of the design together with simulation results of the electromagnetic cavity field, magnetic field, electron trajectories, and thermal analyses are presented.« less

The value of Tyler Volk’s Quarks to Culture is evident when the book is placed against popular histories of the universe, dozens of which have provided evidence for an immense cosmic past. But such histories are often anecdotal, like early British histories of the kings of England. Unlike these works, Volk artfully presents the case for structural continuity and systematic cre­ativity across 13.8 billion years of cosmic history.

Knowledge diffusion in social work: a new approach to bridging the gap.

PubMed

Herie, Marilyn; Martin, Garth W

2002-01-01

The continuing gap between research and practice has long been a problem in social work. A great deal of the empirical practice literature has emphasized practice evaluation (usually in the form of single-case methodologies) at the expense of research dissemination and utilization. An alternative focus for social work researchers can be found in the extensive theoretical and research literature on knowledge diffusion, technology transfer, and social marketing. Knowledge diffusion and social marketing theory is explored in terms of its relevance to social work education and practice, including a consideration of issues of culture and power. The authors present an integrated dissemination model for social work and use a case example to illustrate the practical application of the model. The OPTIONS (OutPatient Treatment In ONtario Services) project is an example of the effective dissemination of two research-based addiction treatment modalities to nearly 1,000 direct practice clinicians in Ontario, Canada.

Gender issues in the university research environment

Recruiting and retaining females within science, engineering and technology continues to challenge many European higher education institutions. This study looks at female self-perceptions relating to effective research work and career progression. Focus groups are used to examine the attitudes and experiences of females and a questionnaire is used to explore perceptions in four main skills areas: group work; communication; personal awareness; project planning and management. The study indicates consistent female concerns on issues pertaining to effective female role models, negative work-role stereotypes and the work-life balance of an academic career. For all four skills areas, the average confidence scores of the female participants fell below those of males, but these differences were only statistically significant for perceptions on group work and communication skills and prior to an intense skills development course. Based on these findings, a student workshop on gender issues has been developed, an outline of which is presented.

Stress in health care professionals may reflect both the work and appraisal of work and impacts on the individuals, their patients, colleagues and managers. The purpose of the present study is to examine physiological and psychological effects of stressors (tasks) and theory-based perceptions of work stressors within and between nurses in real time. During two work shifts, 100 nurses rated experienced stress, affect, fatigue, theory-based measures of work stress and nursing tasks on electronic diaries every 90 min, whereas heart rate and activity were measured continuously. Heart rate was associated with both demand and effort. Experienced stress was related to demand, control, effort and reward. Effort and reward interacted as predicted (but only within people). Results were unchanged when allowance was made for work tasks. Real-time appraisals were more important than actual tasks in predicting both psychological and physiological correlates of stress. At times when effort was high, perceived reward reduced stress.

Ongoing research into the use and conservation of energy in Kenya is reported briefly. A partial accounting of energy use in Kenya is presented, and evidence that some energy conservation has been taking place is discussed. A fuller accounting for all commercial energy flows is both possible and desirable. The work presented should serve as a basis for further data collection and analysis in Kenya, and can be used as a model for similar efforts in other countries. The author intends to continue much of this energy accounting in Kenya in the latter half of 1980.

Despite on the improvements in the quality of high-rise construction areas and industrial wastewater treatment, the pollution of water bodies continues to increase. This is due to the organized and unorganized surface untreated sewage entry into the reservoirs. The qualitative analysis of some cities' surface sewage composition is carried out in the work. Based on the published literature review, the characteristic contamination present in surface wastewater was identified. The paper proposes a new technology for the treatment of surface sewage and presents the results of preliminary studies.

In 1984, researchers from Ames Research Center came together to develop advanced human interfaces for NASA s teleoperations that would come to be known as "virtual reality." The basis of the work theorized that if the sensory interfaces met a certain threshold and sufficiently supported each other, then the operator would feel present in the remote/synthetic environment, rather than present in their physical location. Twenty years later, this prolific research continues to pay dividends to society in the form of cutting-edge virtual reality products, such as an interactive audio simulation system.

The work presented here is the first part of a continuing effort to expand existing capabilities in aeroelasticity by developing the methodology which is necessary to utilize unsteady time-domain aerodynamics directly in aeroservoelastic design and analysis. The ultimate objective is to define a fully integrated state-space model of an aeroelastic vehicle's aerodynamics, structure and controls which may be used to efficiently determine the vehicle's aeroservoelastic stability. Here, the current status of developing a state-space model for linear or near-linear time-domain indicial aerodynamic forces is presented.

The pearls of using real-world evidence to discover social groups

NASA Astrophysics Data System (ADS)

Cardillo, Raymond A.; Salerno, John J.

2005-03-01

In previous work, we introduced a new paradigm called Uni-Party Data Community Generation (UDCG) and a new methodology to discover social groups (a.k.a., community models) called Link Discovery based on Correlation Analysis (LDCA). We further advanced this work by experimenting with a corpus of evidence obtained from a Ponzi scheme investigation. That work identified several UDCG algorithms, developed what we called "Importance Measures" to compare the accuracy of the algorithms based on ground truth, and presented a Concept of Operations (CONOPS) that criminal investigators could use to discover social groups. However, that work used a rather small random sample of manually edited documents because the evidence contained far too many OCR and other extraction errors. Deferring the evidence extraction errors allowed us to continue experimenting with UDCG algorithms, but only used a small fraction of the available evidence. In attempt to discover techniques that are more practical in the near-term, our most recent work focuses on being able to use an entire corpus of real-world evidence to discover social groups. This paper discusses the complications of extracting evidence, suggests a method of performing name resolution, presents a new UDCG algorithm, and discusses our future direction in this area.

Occupational asthma in electronics workers caused by colophony fumes: follow-up of affected workers.

PubMed

Burge, P S

1982-05-01

Thirty-nine electronics workers were investigated by bronchial provocation testing to soldering fluxes containing colophony and were followed up one to four years later. At presentation and on follow-up each worker had nonspecific bronchial reactivity measured with inhaled histamine, and also had detailed measurements of lung function and estimation of total immunoglobulin levels. They completed a questionnaire designed to detect residual disability. The workers were divided into three groups. Twenty had left work after their initial diagnosis, eight had been moved to alternative work within their original factories, and 11 were thought to have asthma unrelated to colophony exposure as they failed to react to colophony at presentation. Histamine reactivity had returned to normal in half the workers who had left their original factories, but in only one worker who had moved within her original factory. This suggested that the nonspecific bronchial reactivity to histamine was the result rather than the cause of the occupational asthma, and that indirect exposure at work was sufficient to delay recovery of histamine reactivity. However, only two of the 20 affected workers who had left their original factories were symptom free on follow-up, and most had a considerable reduction in their quality of life by continuing asthma, which was particularly provoked by exercise, respiratory infections, and nonspecific irritants. Continuing symptoms may have been caused by domestic sources of colophony, or possibly the failure to eliminate colophony from the lungs.

From Brown-Peterson to continual distractor via operation span: A SIMPLE account of complex span.

PubMed

Neath, Ian; VanWormer, Lisa A; Bireta, Tamra J; Surprenant, Aimée M

2014-09-01

Three memory tasks-Brown-Peterson, complex span, and continual distractor-all alternate presentation of a to-be-remembered item and a distractor activity, but each task is associated with a different memory system, short-term memory, working memory, and long-term memory, respectively. SIMPLE, a relative local distinctiveness model, has previously been fit to data from both the Brown-Peterson and continual distractor tasks; here we use the same version of the model to fit data from a complex span task. Despite the many differences between the tasks, including unpredictable list length, SIMPLE fit the data well. Because SIMPLE posits a single memory system, these results constitute yet another demonstration that performance on tasks originally thought to tap different memory systems can be explained without invoking multiple memory systems.

Excitation of Continuous and Discrete Modes in Incompressible Boundary Layers

NASA Technical Reports Server (NTRS)

Ashpis, David E.; Reshotko, Eli

1998-01-01

This report documents the full details of the condensed journal article by Ashpis & Reshotko (JFM, 1990) entitled "The Vibrating Ribbon Problem Revisited." A revised formal solution of the vibrating ribbon problem of hydrodynamic stability is presented. The initial formulation of Gaster (JFM, 1965) is modified by application of the Briggs method and a careful treatment of the complex double Fourier transform inversions. Expressions are obtained in a natural way for the discrete spectrum as well as for the four branches of the continuous spectra. These correspond to discrete and branch-cut singularities in the complex wave-number plane. The solutions from the continuous spectra decay both upstream and downstream of the ribbon, with the decay in the upstream direction being much more rapid than that in the downstream direction. Comments and clarification of related prior work are made.

Continuous-variable quantum cryptography with an untrusted relay: Detailed security analysis of the symmetric configuration

NASA Astrophysics Data System (ADS)

Ottaviani, Carlo; Spedalieri, Gaetana; Braunstein, Samuel L.; Pirandola, Stefano

2015-02-01

We consider the continuous-variable protocol of Pirandola et al. [arXiv:1312.4104] where the secret key is established by the measurement of an untrusted relay. In this network protocol, two authorized parties are connected to an untrusted relay by insecure quantum links. Secret correlations are generated by a continuous-variable Bell detection performed on incoming coherent states. In the present work we provide a detailed study of the symmetric configuration, where the relay is midway between the parties. We analyze symmetric eavesdropping strategies against the quantum links explicitly showing that, at fixed transmissivity and thermal noise, two-mode coherent attacks are optimal, manifestly outperforming one-mode collective attacks based on independent entangling cloners. Such an advantage is shown both in terms of security threshold and secret-key rate.

Two broad theories of visual working memory (VWM) storage have emerged from current research, a discrete slot-based theory and a continuous resource theory. However, neither the discrete slot-based theory or continuous resource theory clearly stipulates how the mental commodity for VWM (discrete slot or continuous resource) is allocated.…

Catching a quantum jump in mid-flight

Quantum jumps provide a fundamental manifestation of the interplay between coherent dynamics and strong continuous measurements. Interestingly, the modern theoretical vantage point of quantum trajectories (Carmichael, 1993) suggests that the jump is not instantaneous, but rather smooth, coherent, and under the right conditions may present a deterministic character. We revisit the original observation of quantum jumps in a V-type, three-level atom (Berquist, 1986; Sauter, 1986), in order to ``deterministically'' catch the jump in mid-flight. We have designed and operated a V-type superconducting artificial atom with the 3 needed levels: G (for Ground), B (for Bright), and D (for Dark). The atom is coupled to a continuously monitored microwave mode that can distinguish B from the manifold formed by G and D, but without distinguishing G from D. We will present preliminary results showing how this experiment can be realized. Work supported by: ARO, ONR, AFOSR and YINQE. Discussions with H. Carmichael are gratefully acknowledged.

Predicting Innovation Acceptance by Simulation in Virtual Environments (Theoretical Foundations)

NASA Astrophysics Data System (ADS)

León, Noel; Duran, Roberto; Aguayo, Humberto; Flores, Myrna

This paper extends the current development of a methodology for Computer Aided Innovation. It begins with a presentation of concepts related to the perceived capabilities of virtual environments in the Innovation Cycle. The main premise establishes that it is possible to predict the acceptance of a new product in a specific market, by releasing an early prototype in a virtual scenario to quantify its general reception and to receive early feedback from potential customers. The paper continues to focus this research on a synergistic extension of techniques that have their origins in optimization and innovation disciplines. TRIZ (Theory of Inventive Problem Solving), extends the generation of variants with Evolutionary Algorithms (EA) and finally to present the designer and the intended customer, creative and innovative alternatives. All of this developed on a virtual software interface (Virtual World). The work continues with a general description of the project as a step forward to improve the overall strategy.

Teleportation-based continuous variable quantum cryptography

NASA Astrophysics Data System (ADS)

Luiz, F. S.; Rigolin, Gustavo

2017-03-01

We present a continuous variable (CV) quantum key distribution (QKD) scheme based on the CV quantum teleportation of coherent states that yields a raw secret key made up of discrete variables for both Alice and Bob. This protocol preserves the efficient detection schemes of current CV technology (no single-photon detection techniques) and, at the same time, has efficient error correction and privacy amplification schemes due to the binary modulation of the key. We show that for a certain type of incoherent attack, it is secure for almost any value of the transmittance of the optical line used by Alice to share entangled two-mode squeezed states with Bob (no 3 dB or 50% loss limitation characteristic of beam splitting attacks). The present CVQKD protocol works deterministically (no postselection needed) with efficient direct reconciliation techniques (no reverse reconciliation) in order to generate a secure key and beyond the 50% loss case at the incoherent attack level.

The aim of the study was to present an observation method focusing on the positions of the hands relative to the body and to evaluate whether this simple observation technique gives a reliable estimate of the total time spent in each of five work postures during one workday. In the first part of the study the interobserver reliability of the observation method was tested with eight blue-collar workers. In the second part the observed time spent with work above the shoulder level was tested in relation to an upper-arm position analyzer, and observed time spent in work below knuckle level was tested in relation to a trunk flexion analyzer, both with 72 blue-collar workers. The interobserver reliability for full-day registrations was high. The intraclass correlation coefficients ranged from 0.99 to 1.00. The observed duration of work with hands above shoulder level correlated well with the measured duration of pronounced arm elevation (> 75 degrees). The product moment correlation coefficient was 0.97. The observed duration of work with hands below knuckle level correlated well with the measured duration of pronounced trunk flexion angles (> 40 degrees). The product moment correlation coefficient was 0.98. The present observation method, designed to make postural observations continuously for several hours, is easy to learn and seems reliable.

Comparative study of lesions created by high-intensity focused ultrasound using sequential discrete and continuous scanning strategies.

2013-03-01

Lesion formation and temperature distribution induced by high-intensity focused ultrasound (HIFU) were investigated both numerically and experimentally via two energy-delivering strategies, i.e., sequential discrete and continuous scanning modes. Simulations were presented based on the combination of Khokhlov-Zabolotskaya-Kuznetsov (KZK) equation and bioheat equation. Measurements were performed on tissue-mimicking phantoms sonicated by a 1.12-MHz single-element focused transducer working at an acoustic power of 75 W. Both the simulated and experimental results show that, in the sequential discrete mode, obvious saw-tooth-like contours could be observed for the peak temperature distribution and the lesion boundaries, with the increasing interval space between two adjacent exposure points. In the continuous scanning mode, more uniform peak temperature distributions and lesion boundaries would be produced, and the peak temperature values would decrease significantly with the increasing scanning speed. In addition, compared to the sequential discrete mode, the continuous scanning mode could achieve higher treatment efficiency (lesion area generated per second) with a lower peak temperature. The present studies suggest that the peak temperature and tissue lesion resulting from the HIFU exposure could be controlled by adjusting the transducer scanning speed, which is important for improving the HIFU treatment efficiency.

In this paper, we present a simultaneous and continuous kinematics estimation method for multiple DoFs across shoulder and elbow joint. Although simultaneous and continuous kinematics estimation from surface electromyography (EMG) is a feasible way to achieve natural and intuitive human-machine interaction, few works investigated multi-DoF estimation across the significant joints of upper limb, shoulder and elbow joints. This paper evaluates the feasibility to estimate 4-DoF kinematics at shoulder and elbow during coordinated arm movements. Considering the potential applications of this method in exoskeleton, prosthetics and other arm rehabilitation techniques, the estimation performance is presented with different muscle activity decomposition and learning strategies. Principle component analysis (PCA) and independent component analysis (ICA) are respectively employed for EMG mode decomposition with artificial neural network (ANN) for learning the electromechanical association. Four joint angles across shoulder and elbow are simultaneously and continuously estimated from EMG in four coordinated arm movements. By using ICA (PCA) and single ANN, the average estimation accuracy 91.12% (90.23%) is obtained in 70-s intra-cross validation and 87.00% (86.30%) is obtained in 2-min inter-cross validation. This result suggests it is feasible and effective to use ICA (PCA) with single ANN for multi-joint kinematics estimation in variant application conditions. PMID:28611573

We present test results of the first adiabatic demagnetization refrigerator (ADR) that can produce continuous cooling at sub-kelvin temperatures. This system uses multiple stages that operate in sequence to cascade heat from a continuous stage up to a heat sink. Continuous operation aids the usual constraints of long hold times and short recycle times that lead to the generally large mass of single-shot ADRs, and allows us to achieve much higher cooling power per unit mass. Our design goal is 10 microW of cooling at 50 mK while rejecting heat to a 6-10 K heat sink. The total cold mass is estimated to be less than 10 kg, including magnetic shielding of each stage. These parameters envelop the requirements for currently planned astronomy missions. The relatively high heat rejection capability allows it to operate with a mechanical cryocooler as part of a cryogen-free, low temperature cooling system. This has the advantages of long, mission life and reduced complexity and cost. At present, we have assembled a three-stage ADR that operates with a superfluid helium bath. Additional work is underway to develop magnetocaloric materials that can extend its heat rejection capability up to 10 K. This paper discusses the design and operation of the ADR, as well as interface requirements for cryocooler-based operation.

2017-01-01

Inductive machine learning, and in particular extraction of association rules from data, has been successfully used in multiple application domains, such as market basket analysis, disease prognosis, fraud detection, and protein sequencing. The appeal of rule extraction techniques stems from their ability to handle intricate problems yet produce models based on rules that can be comprehended by humans, and are therefore more transparent. Human comprehension is a factor that may improve adoption and use of data-driven decision support systems clinically via face validity. In this work, we explore whether we can reliably and informatively forecast cardiorespiratory instability (CRI) in step-down unit (SDU) patients utilizing data from continuous monitoring of physiologic vital sign (VS) measurements. We use a temporal association rule extraction technique in conjunction with a rule fusion protocol to learn how to forecast CRI in continuously monitored patients. We detail our approach and present and discuss encouraging empirical results obtained using continuous multivariate VS data from the bedside monitors of 297 SDU patients spanning 29 346 hours (3.35 patient-years) of observation. We present example rules that have been learned from data to illustrate potential benefits of comprehensibility of the extracted models, and we analyze the empirical utility of each VS as a potential leading indicator of an impending CRI event.

The dissertation provides an excellent source of scholarly productivity for new doctoral faculty, yet is often neglected because of the demands inherent in the faculty role. The purpose of this paper is to present a case study of a scholar mentor group composed of three graduates of a PhD nursing program and their shared dissertation chair, who acted as a senior scholar mentor to the group. By working together, we have been able to enhance our scholarly productivity by disseminating our dissertations through presentations and publications. The paper will present the evolving process of this working group, summarize outcomes, analyze the challenges, and provide suggestions for future doctoral students and faculty who are working with them. Our experience and scholar mentor model captures the best of both worlds-the benefits of interaction with academic peers and the benefits of having a senior scholar mentor. This was accomplished while all members were at different schools in different cities and states. Although other literatures that document successful collaborations using a peer-mentorship model are available, we were unable to locate any that documents a post-doctoral group with a senior scholar mentor who continued working together after graduation. © 2015 Wiley Periodicals, Inc.

Correlates of Injury-forced Work Reduction for Massage Therapists and Bodywork Practitioners.

2013-01-01

Injury-forced work reduction (IFWR) has been acknowledged as an all-too-common occurrence for massage therapists and bodywork practitioners (M & Bs). However, little prior research has specifically investigated demographic, work attitude, and perceptual correlates of IFWR among M & Bs. To test two hypotheses, H1 and H2. H1 is that the accumulated cost variables set ( e.g., accumulated costs, continuing education costs) will account for a significant amount of IFWR variance beyond control/demographic (e.g., social desirability response bias, gender, years in practice, highest education level) and work attitude/perception variables (e.g., job satisfaction, affective occupation commitment, occupation identification, limited occupation alternatives) sets. H2 is that the two exhaustion variables (i.e., physical exhaustion, work exhaustion) set will account for significant IFWR variance beyond control/demographic, work attitude/perception, and accumulated cost variables sets. An online survey sample of 2,079 complete-data M & Bs was collected. Stepwise regression analysis was used to test the study hypotheses. The research design first controlled for control/demographic (Step1) and work attitude/perception variables sets (Step 2), before then testing for the successive incremental impact of two variable sets, accumulated costs (Step 3) and exhaustion variables (Step 4) for explaining IFWR. RESULTS SUPPORTED BOTH STUDY HYPOTHESES: accumulated cost variables set (H1) and exhaustion variables set (H2) each significantly explained IFWR after the control/demographic and work attitude/perception variables sets. The most important correlate for explaining IFWR was higher physical exhaustion, but work exhaustion was also significant. It is not just physical "wear and tear", but also "mental fatigue", that can lead to IFWR for M & Bs. Being female, having more years in practice, and having higher continuing education costs were also significant correlates of IFWR. Lower overall levels of work exhaustion, physical exhaustion, and IFWR were found in the present sample. However, since both types of exhaustion significantly and positively impact IFWR, taking sufficient time between massages and, if possible, varying one's massage technique to replenish one's physical and mental energy seem important. Failure to take required continuing education units, due to high costs, also increases risk for IFWR. Study limitations and future research issues are discussed.

Depression, anxiety and stress are common problems for modern workers. Although having meaningful work, or work that is significant, facilitates personal growth, and contributes to the greater good, has been linked to better mental health, people's work might also need to be satisfying or enjoyable to improve outcomes. The purpose of the present study was to examine meaningful work's relation to mental health (i.e. depression, anxiety and stress) and investigate job satisfaction as a moderator of this relation. The study hypotheses were tested with a large, diverse sample recruited from an online source. Partially supporting hypotheses, when controlling for job satisfaction, meaningful work negatively correlated with depression but did not have a significant relation with anxiety and stress. Similarly, job satisfaction negatively predicted depression and stress. Furthermore, the relations between meaningful work and both anxiety and stress were moderated by job satisfaction. Specifically, only people perceiving their work as meaningful and satisfying reported less anxiety and stress. Although continued research is needed, employers and employees may have to target both the meaningfulness and job satisfaction to address the issues of stress and anxiety among working adults.

Past and Future Work on Radiobiology Mega-Studies: A Case Study At Argonne National Laboratory

Between 1952 and 1992, more than 200 large radiobiology studies were conducted in research institutes throughout Europe, North America, and Japan to determine the effects of external irradiation and internal emitters on the lifespan and tissue toxicity development in animals. At Argonne National Laboratory, 22 external beam studies were conducted on nearly 700 beagle dogs and 50,000 mice between 1969 and 1992. These studies helped to characterize the effects of neutron and gamma irradiation on lifespan, tumorigenesis, and mutagenesis across a range of doses and dosing patterns. The records and tissues collected at Argonne during that time period have beenmore » carefully preserved and redisseminated. Using these archived data, ongoing statistical work has been done and continues to characterize quality of radiation, dose, dose rate, tissue, and gender-specific differences in the radiation responses of exposed animals. The ongoing application of newly-developed molecular biology techniques to the archived tissues has revealed gene-specific mutation rates following exposure to ionizing irradiation. The original and ongoing work with this tissue archive is presented here as a case study of a more general trend in the radiobiology megastudies. These experiments helped form the modern understanding of radiation responses in animals and continue to inform development of new radiation models. Recent archival efforts have facilitated open access to the data and materials produced by these studies, and so a unique opportunity exists to expand this continued research.« less

Developing a Continuous Bioprocessing Approach to Stromal Cell Manufacture.

To this day, the concept of continuous bioprocessing has been applied mostly to the manufacture of molecular biologics such as proteins, growth factors, and secondary metabolites with biopharmaceutical uses. The present work now sets to explore the potential application of continuous bioprocess methods to source large numbers of human adherent cells with potential therapeutic value. To this purpose, we developed a smart multifunctional surface coating capable of controlling the attachment, proliferation, and subsequent self-detachment of human corneal stromal cells. This system allowed the maintenance of cell cultures under steady-state growth conditions, where self-detaching cells were continuously replenished by the proliferation of those remaining attached. This facilitated a closed, continuous bioprocessing platform with recovery of approximately 1% of the total adherent cells per hour, a yield rate that was maintained for 1 month. Moreover, both attached and self-detached cells were shown to retain their original phenotype. Together, these results represent the proof-of-concept for a new high-throughput, high-standard, and low-cost biomanufacturing strategy with multiple potentials and important downstream applications.

Sleep problems across development: a pathway to adolescent risk taking through working memory.

Thomas, April Gile; Monahan, Kathryn C; Lukowski, Angela F; Cauffman, Elizabeth

2015-02-01

Problematic sleep can be detrimental to the development of important cognitive functions, such as working memory, and may have the potential for negative behavioral consequences, such as risk-taking. In this way, sleep problems may be particularly harmful for youth-whose cognitive abilities are still developing and who are more susceptible to risky behavior. Using data from a large, national, longitudinal study, continuity and change in sleep problems were examined from 2 to 15 years of age and associated with deficits in working memory at age 15 and risk taking behaviors at age 18. Participants (N = 1,364 children; 48.3% female) were assessed for sleep problems (parent-report), working memory (behavioral task), and risk taking behavior (youth self-report). The sample was predominantly White (80.4%); additional races represented in the sample included Black/African American (12.9%), Asian/Pacific Islander (1.6%), American Indian/Eskimo/Aleut (.4%), and Other (4.7%). The findings suggest that sleep problems are likely to cascade across development, with sleep problems demonstrating continuity from infancy to early childhood, early childhood to middle childhood, and middle childhood to adolescence. Although sleep problems in infancy, early childhood, and middle childhood were not directly related to adolescent working memory, sleep problems during adolescence were associated with poorer adolescent working memory. In turn, these deficits in working memory were related to greater risk taking in late adolescence. In summary, the present results suggest that sleep problems in earlier periods are indicative of risk for sleep problems later in development, but that sleep problems in adolescence contribute uniquely to deficits in working memory that, in turn, lead to risky behavior during late adolescence.

Health care work environments, employee satisfaction, and patient safety: Care provider perspectives.

Rathert, Cheryl; May, Douglas R

Experts continue to decry the lack of progress made in decreasing the alarming frequency of medical errors in health care organizations (Leape, L. L., & Berwick, D. M. (2005). Five years after to err is human: What have we learned?. Journal of the American Medical Association, 293(19), 2384-2390). At the same time, other experts are concerned about the lack of job satisfaction and turnover among nurses (. Keeping patients safe: Transforming the work environment of nurses. Washington, DC: National Academy Press). Research and theory suggest that a work environment that facilitates patient-centered care should increase patient safety and nurse satisfaction. The present study began with a conceptual model that specifies how work environment variables should be related to both nurse and patient outcomes. Specifically, we proposed that health care work units with climates for patient-centered care should have nurses who are more satisfied with their jobs. Such units should also have higher levels of patient safety, with fewer medication errors. We examined perceptions of nurses from three acute care hospitals in the eastern United States. Nurses who perceived their work units as more patient centered were significantly more satisfied with their jobs than were those whose units were perceived as less patient centered. Those whose work units were more patient centered reported that medication errors occurred less frequently in their units and said that they felt more comfortable reporting errors and near-misses than those in less patient-centered units. Patients and quality leaders continue to call for delivery of patient-centered care. If climates that facilitate such care are also related to improved patient safety and nurse satisfaction, proactive, patient-centered management of the work environment could result in improved patient, employee, and organizational outcomes.

Large Area Silicon Sheet by EFG. [quality control and productivity of edge-defined film-fed growth of ribbons

Influences on ribbon quality which might be caused by various materials of construction which are used in the growth furnace were assessed. At the present level of ribbon quality, which has produced 8.5% to 9.5% efficient solar cells, no particular influence of any furnace part was detected. The experiments led to the suspicion that the general environment and the somewhat unoptimized materials handling procedures might be responsible for the current variations in ribbon quality and that, therefore, continuous work with this furnace under rather more stringent environmental conditions and operating procedures could perhaps improve materials quality to some extent. The work on the multiple furnace was continued with two multiple growth runs being performed. In these runs, the melt replenishment system performed poorly and extensive modifications to it were designed to make reliable melt feeding for five ribbon growth possible. Additional characterization techniques for wide ribbons, stress measurements, and growth dynamics experiments are reported.

Transcatheter closure of a small atrial septal defect with an Amplatzer™ patent foramen ovale occluder in a working dog with cyanosis and exercise intolerance at high altitude.

A 6.5-year-old male Border Collie presented for transcatheter closure of an atrial septal defect due to exercise intolerance and cyanosis while working and training at altitude. A small, left-to-right shunting secundum atrial septal defect was confirmed with no evidence of significant right-sided volume overload. Pulmonary hypertension with subsequent right-to-left interatrial shunting occurring during exercise at high altitude was suspected and prompted the closure of the defect due to the dog's continued athletic requirements. The anatomy of the defect prompted use of a patent foramen ovale occluder rather than an atrial septal defect occluder, which was deployed using a combination of fluoroscopic and transesophageal echocardiographic guidance. The owner did not report continued exercise intolerance or cyanosis and the dog's lifestyle and residence at altitude was unchanged. Copyright © 2017 Elsevier B.V. All rights reserved.

On the continuing relevance of Mandelbrot's non-ergodic fractional renewal models of 1963 to 1967

Watkins, Nicholas W.

2017-12-01

The problem of "1/f" noise has been with us for about a century. Because it is so often framed in Fourier spectral language, the most famous solutions have tended to be the stationary long range dependent (LRD) models such as Mandelbrot's fractional Gaussian noise. In view of the increasing importance to physics of non-ergodic fractional renewal models, and their links to the CTRW, I present preliminary results of my research into the history of Mandelbrot's very little known work in that area from 1963 to 1967. I speculate about how the lack of awareness of this work in the physics and statistics communities may have affected the development of complexity science, and I discuss the differences between the Hurst effect, "1/f" noise and LRD, concepts which are often treated as equivalent.

2015-06-01

Acute care nurse practitioners, prepared as providers for a variety of populations of patients, continue to make substantial contributions to health care. Evidence indicates shorter stays, higher satisfaction among patients, increased work efficiency, and higher quality outcomes when acute care nurse practitioners are part of unit- or service-based provider teams. The Consensus Model for APRN Regulation: Licensure, Accreditation, Certification, and Education outlines detailed guidelines for matching nurse practitioners' education with certification and practice by using a population-focused algorithm. Despite national support for the model, nurse practitioners and employers continue to struggle with finding the right fit. Nurse practitioners often use their interest and previous nursing experience to apply for an available position, and hospitals may not understand preparation or regulations related to matching the appropriate provider to the work environment. Evidence and regulatory guidelines indicate appropriate providers for population-focused positions. This article presents history and recommendations for hiring acute care nurse practitioners as providers for different populations of patients. ©2015 American Association of Critical-Care Nurses.

Satellite-derived clear-sky vs. cloudy-sky discrimination at the pixel scale is an important input parameter used in many real-time applications. Cloud fractions, resulting from integrating over time and space, are also critical to the study of recent decadal climate changes. The NASA NPOESS Preparatory Project (NPP) has funded a science team to develop and study the ability to make continuous climate records from MODIS (2000-2020) and VIIRS (2012-2030). The MODAWG project, led by Dr. Steve Platnick of NASA/GSFC, combines elements of the MODIS processing system and the NOAA Algorithm Working Group (AWG) to achieve this goal. This presentation will focus on the cloud masking aspects of MODAWG, derived primarily from the MODIS cloud mask (MOD35). Challenges to continuity of cloud detection due to differences in instrument characteristics will be discussed. Cloud mask results from use of the same (continuity) algorithm will be shown for both MODIS and VIIRS, including comparisons to collocated CALIOP (Cloud-Aerosol Lidar with Orthogonal Polarization) cloud data.

Secret communication over public channels is one of the central pillars of a modern information society. Using quantum key distribution this is achieved without relying on the hardness of mathematical problems, which might be compromised by improved algorithms or by future quantum computers. State-of-the-art quantum key distribution requires composable security against coherent attacks for a finite number of distributed quantum states as well as robustness against implementation side channels. Here we present an implementation of continuous-variable quantum key distribution satisfying these requirements. Our implementation is based on the distribution of continuous-variable Einstein-Podolsky-Rosen entangled light. It is one-sided device independent, which means the security of the generated key is independent of any memoryfree attacks on the remote detector. Since continuous-variable encoding is compatible with conventional optical communication technology, our work is a step towards practical implementations of quantum key distribution with state-of-the-art security based solely on telecom components.

Dynamic allocation of same-day requests in multi-physician primary care practices in the presence of prescheduled appointments.

Balasubramanian, Hari; Biehl, Sebastian; Dai, Longjie; Muriel, Ana

2014-03-01

Appointments in primary care are of two types: 1) prescheduled appointments, which are booked in advance of a given workday; and 2) same-day appointments, which are booked as calls come during the workday. The challenge for practices is to provide preferred time slots for prescheduled appointments and yet see as many same-day patients as possible during regular work hours. It is also important, to the extent possible, to match same-day patients with their own providers (so as to maximize continuity of care). In this paper, we present a mathematical framework (a stochastic dynamic program) for same-day patient allocation in multi-physician practices in which calls for same-day appointments come in dynamically over a workday. Allocation decisions have to be made in the presence of prescheduled appointments and without complete demand information. The objective is to maximize a weighted measure that includes the number of same-day patients seen during regular work hours as well as the continuity provided to these patients. Our experimental design is motivated by empirical data we collected at a 3-provider family medicine practice in Massachusetts. Our results show that the location of prescheduled appointments - i.e. where in the day these appointments are booked - has a significant impact on the number of same-day patients a practice can see during regular work hours, as well as the continuity the practice is able to provide. We find that a 2-Blocks policy which books prescheduled appointments in two clusters - early morning and early afternoon - works very well. We also provide a simple, easily implementable policy for schedulers to assign incoming same-day requests to appointment slots.

This work analyzes the long-term functionality of HP (High-power) UV-LEDs (Ultraviolet Light Emitting Diodes) as the exciting light source in non-contact, continuous 24/7 real-time fluoro-sensing pollutant identification in inland water. Fluorescence is an effective alternative in the detection and identification of hydrocarbons. The HP UV-LEDs are more advantageous than classical light sources (xenon and mercury lamps) and helps in the development of a low cost, non-contact, and compact system for continuous real-time fieldwork. This work analyzes the wavelength, output optical power, and the effects of viscosity, temperature of the water pollutants, and the functional consistency for long-term HP UV-LED working operation. To accomplish the latter, an analysis of the influence of two types 365 nm HP UV-LEDs degradation under two continuous real-system working mode conditions was done, by temperature Accelerated Life Tests (ALTs). These tests estimate the mean life under continuous working conditions of 6200 h and for cycled working conditions (30 s ON & 30 s OFF) of 66,000 h, over 7 years of 24/7 operating life of hydrocarbon pollution monitoring. In addition, the durability in the face of the internal and external parameter system variations is evaluated. PMID:26927113

Recognition Decisions From Visual Working Memory Are Mediated by Continuous Latent Strengths.

PubMed

Ricker, Timothy J; Thiele, Jonathan E; Swagman, April R; Rouder, Jeffrey N

2017-08-01

Making recognition decisions often requires us to reference the contents of working memory, the information available for ongoing cognitive processing. As such, understanding how recognition decisions are made when based on the contents of working memory is of critical importance. In this work we examine whether recognition decisions based on the contents of visual working memory follow a continuous decision process of graded information about the correct choice or a discrete decision process reflecting only knowing and guessing. We find a clear pattern in favor of a continuous latent strength model of visual working memory-based decision making, supporting the notion that visual recognition decision processes are impacted by the degree of matching between the contents of working memory and the choices given. Relation to relevant findings and the implications for human information processing more generally are discussed. Copyright © 2016 Cognitive Science Society, Inc.

When policy meets physiology: the challenge of reducing resident work hours.

PubMed

Lockley, Steven W; Landrigan, Christopher P; Barger, Laura K; Czeisler, Charles A

2006-08-01

Considerable controversy exists regarding optimal work hours for physicians and surgeons in training. In a series of studies, we assessed the effect of extended work hours on resident sleep and health as well as patient safety. In a validated nationwide survey, we found that residents who had worked 24 hours or longer were 2.3 times more likely to have a motor vehicle crash following that shift than when they worked < 24 hours, and that the monthly risk of a crash increased by 16.2% after each extended duration shift. We also found in a randomized trial that interns working a traditional on-call schedule slept 5.8 hours less per week, had twice as many attentional failures on duty overnight, and made 36% more serious medical errors and nearly six times more serious diagnostic errors than when working on a schedule that limited continuous duty to 16 hours. While numerous opinions have been published opposing reductions in extended work hours due to concerns regarding continuity of patient care, reduced educational opportunities, and traditionally-defined professionalism, there are remarkably few objective data in support of continuing to schedule medical trainees to work shifts > 24 hours. An evidence-based approach is needed to minimize the well-documented risk that current work hour practices confer on resident health and patient safety while optimizing education and continuity of care.

Health and safety strategies in a changing Europe.

PubMed

Walters, D

1998-01-01

This article presents a synthesis of some of the more significant findings from two recent surveys on working conditions and national strategies for their improvement in the European Union in the 1990s. As patterns and organization of employment have changed in the past decade, the consequences for health and safety present new challenges for legislators, the social partners, the regulatory agencies, and the specialists. These challenges are only partially met in most European member states. Because of the continued deregulation of employment, reduced public expenditure, and reduced trade union presence, the operation of strategies to implement a common framework of E.U. legislation is limited and often incomplete. This issue must be confronted if systems for promoting the well-being of people at work in Europe are to keep up with the rapidly changing nature of the risks that they face.

[The cinema as a device for teaching complexity in mental health].

Delego, Adriana; Carroll, Hugo

2013-01-01

This article proposes the use of Cinema as an instrument for a complex approach to Teaching in the field of Clinical Psychiatry and Psychopathology in Mental Health. With this aim, intends a different look that pretends the approach not only to the conceptual structures on Psychopathology, but also to the complexity involved, choosing Cinema as a powerful way of "empathic recreation". Based on previous work by several authors, the theoretical framework that supports this modality is presented in the philosophical, cognitive, pedagogical-didactic aspects and their consequences into teaching within Mental Health. This task also implies addressing the historical evolution of the representation of subjectivity in fiction. In this way, a new perspective to those working in the field of mental health, as subjects involved in continuous learning processes, is presented. This perspective emphasizes the interactions underlying psychic problematical.

The vaccine enterprise in the United States is a remarkable success story that has resulted in freedom from disease for millions of children. Although some persons believe that this success is in danger because of recent vaccine shortages, the reality is otherwise. The existing system fundamentally works and should be strengthened and stabilized, to improve delivery of current vaccines and to establish a firm structure into which a new generation of vaccines can be integrated. Ten practical actions to strengthen supplies of vaccine and ensure the stability of these supplies were presented to the National Vaccine Advisory Committee in February 2002. The present article has been updated to include progress made since that time. By building on what is already in place and on what we know works, we can continue to ensure success for years to come.

Virtual grand rounds: a new educational approach in social work that benefits long-term care providers and patients in rural Idaho.

Cunningham, B J; Vande Merwe, R

2009-01-01

Nationwide, rural USA is experiencing a shortage of social workers. In rural Idaho, three state-wide non-profit organizations worked together to develop Virtual Grand Rounds (VGRs), a new approach to delivering continuing education to social workers and residential care coordinators, in order to promote their retention in the workforce. This study examined participant satisfaction and the potential for the delivery system to be replicated in other states. Between July 2002 and December 2006, 740 person-hours (359 attendees x 2.06 hours) of continuing education were delivered to resident care coordinators and social workers in 9 sessions of VGRs. In total, 287 evaluation forms (79% return rate) were collected on the quality of the presentation, the presenter's expertise and delivery, the relevance and value of the presentation to the attendee, and the quality of the technology. The questionnaire consisted of 10 questions that aimed to measure participant satisfaction level, using a five-point Likert scale with a comments section. Programs and presenters received positive scores. Participants approved of the delivery method and the overall satisfaction rating was 4.1. As to whether the information presented would lead to changes in practice, participants responded positively with a score of 3.25. The Telehealth Idaho program contributed to a thorough training for new healthcare employees and for those in rural Idaho unable to attend the annual conference for essential training. Initial successes led to an expansion of the program to include other facility staff, and other topics which provided a new training system and infrastructure. This represents one unique contribution to addressing the rural social workers shortage.

Long-term sick leave and withdrawal from working life is a concern in western countries. In Norway, comprehensive inpatient work rehabilitation may be offered to sick listed individuals at risk of long-term absence from work. Knowledge about prognostic factors for work outcomes after long-term sick leave and work rehabilitation is still limited. The aim of this study was to test a mediation model for various hypothesized biopsychosocial predictors of continued sick leave after inpatient work rehabilitation. One thousand one hundred fifty-five participants on long-term sick leave from eight different work rehabilitation clinics answered comprehensive questionnaires at arrival to the clinic, and were followed with official register data on sickness benefits for 3 years. Structural equation models were conducted, with days on sickness benefits after work rehabilitation as the outcome. Fear avoidance beliefs for work mediated the relation between both musculoskeletal complaints and education on days on sickness benefits after work rehabilitation. The relation between musculoskeletal complaints and fear avoidance beliefs for work was furthermore fully mediated by poor physical function. Previous sick leave had a strong independent effect on continued sick leave after work rehabilitation. Fear avoidance beliefs for work did not mediate the small effect of pseudoneurological complaints on continued sick leave. Poor coping/interaction ability was neither related to continued sick leave nor fear avoidance beliefs for work. The mediation model was partly supported by the data, and provides some possible new insight into how fear avoidance beliefs for work and functional ability may intervene with subjective health complaints and days on sickness benefits after work rehabilitation.

The present work concerns a method of continuous approximation by block of a continuous function; a method of approximation combining the Approach in Stages with the finite domains Least Squares. An identification procedure by sub-domains: basic generating functions are determined step-by-step permitting their weighting effects to be felt. This procedure allows one to be in control of the signs and to some extent of the optimal values of the parameters estimated, and consequently it provides a unique set of solutions that should represent the real physical parameters. Illustrations and comparisons are developed in rubber hyperelastic modeling. To cite this article: T. Beda, C. R. Mecanique 334 (2006).

Weaving child psychoanalysis: Past, present, and future.

Brinich, Paul M

2013-01-01

Using the metaphor of a fabric woven from many threads, this paper describes nine of the many conceptual strands that have contributed to the development of child psychoanalysis over its first century. It notes the unfortunate isolation (sometimes self-imposed) of child analysis from related fields (including adult analysis) and argues that we must recognize both the strengths and weaknesses of our psychoanalytic tools if we are to collaborate with and profit from the work of nonanalytic colleagues. It closes with the suggestion that the continued weaving of child analysis will require the creation of new looms, structures that are able to support a new generation of child analysts and the continued elaboration of the field.

Broadband continuous wave source localization via pair-wise, cochleagram processing

NASA Astrophysics Data System (ADS)

Nosal, Eva-Marie; Frazer, L. Neil

2005-04-01

A pair-wise processor has been developed for the passive localization of broadband continuous-wave underwater sources. The algorithm uses sparse hydrophone arrays and does not require previous knowledge of the source signature. It is applicable in multiple source situations. A spectrogram/cochleagram version of the algorithm has been developed in order to utilize higher frequencies at longer ranges where signal incoherence, and limited computational resources, preclude the use of full waveforms. Simulations demonstrating the robustness of the algorithm with respect to noise and environmental mismatch will be presented, together with initial results from the analysis of humpback whale song recorded at the Pacific Missile Range Facility off Kauai.

New and innovative information technologies drive the ever-evolving library profession. From clay tablet to parchment scroll to manufactured paper to computer screen pixel, information storage, retrieval, and delivery methods continue to evolve, and each advance irrevocably affects the way libraries, and librarians, work. The Internet has forever altered information and library science, both in theory and practice, but even within this context the progression continues. Though ambiguously defined, Web 2.0 offers a new outlook and new software, presenting librarians with potentially invaluable new tools and methods. This paper discusses the creation, implementation, and maintenance of a Web 2.0 technology, the wiki, as a resource tool for an academic biomedical library.

A collision history-based approach to Sensitivity/Perturbation calculations in the continuous energy Monte Carlo code SERPENT

DOE Office of Scientific and Technical Information (OSTI.GOV)

Giuseppe Palmiotti

In this work, the implementation of a collision history-based approach to sensitivity/perturbation calculations in the Monte Carlo code SERPENT is discussed. The proposed methods allow the calculation of the eects of nuclear data perturbation on several response functions: the eective multiplication factor, reaction rate ratios and bilinear ratios (e.g., eective kinetics parameters). SERPENT results are compared to ERANOS and TSUNAMI Generalized Perturbation Theory calculations for two fast metallic systems and for a PWR pin-cell benchmark. New methods for the calculation of sensitivities to angular scattering distributions are also presented, which adopts fully continuous (in energy and angle) Monte Carlo estimators.

Highly parallel demagnetization field calculation using the fast multipole method on tetrahedral meshes with continuous sources

NASA Astrophysics Data System (ADS)

Palmesi, P.; Exl, L.; Bruckner, F.; Abert, C.; Suess, D.

2017-11-01

The long-range magnetic field is the most time-consuming part in micromagnetic simulations. Computational improvements can relieve problems related to this bottleneck. This work presents an efficient implementation of the Fast Multipole Method [FMM] for the magnetic scalar potential as used in micromagnetics. The novelty lies in extending FMM to linearly magnetized tetrahedral sources making it interesting also for other areas of computational physics. We treat the near field directly and in use (exact) numerical integration on the multipole expansion in the far field. This approach tackles important issues like the vectorial and continuous nature of the magnetic field. By using FMM the calculations scale linearly in time and memory.

Fountain-pen-based laser microstructuring with gold nanoparticle inks

NASA Astrophysics Data System (ADS)

Choi, Tae Y.; Poulikakos, Dimos; Grigoropoulos, Costas P.

2004-07-01

Employing the fountain-pen principle, a micropipette is used to write an Au nanoparticle ink on glass substrates. A continuous-wave laser (488-515nm) is subsequently used as a controlled, localized energy source to evaporate the carrier liquid (toluene) in the ink and sinter the nanoparticles together thus fabricating continuous gold stripes 5μm in width and a few hundred nanometers in height. The scanning speed, the laser intensity, and the degree of defocusing are identified as important parameters to the successful manufacturing of the gold microstructures. The electrical resistivity of the stripes, within the parametric domain of the present work, is measured to be the order of 10-6Ωm.

Design of a decision tool for hydromorphological restoration of water bodies in Walloon Region

Lambot, Francis; de Le Court, Bernard; Petit, François; Hallot, Eric; Peeters, Alexandre; Descy, Jean-Pierre; Verniers, Gisèle; Latli, Adrien

2010-05-01

The pilot project WALPHY (LIFE + Environment LIFE07 ENV/B/000038, UE-funded) develops a structured approach aiming at improving hydromorphological quality of the upstream Meuse basin in order to achieve the "good ecological status" required by the Water Framework Directive (WFD 2000/60). It began in January 2009 for a period of 5 years. River's biological recovery needs the recovery of river's structure and physical dynamics. Returning to "good ecological status" inevitably involves physical restoration of affected rivers. Physical component of aquatic environment acts as a limiting factor for their functioning. Three types of modification are key obstacles for river good ecological status: (i) fluxes alteration (discharge, sedimentation…), (ii) forms alteration (uniform facies…) and (iii) biotopes access alteration (lateral connections breaks, modification of the continuity upstream/downstream…). Therefore hydromorphology is needed to implement the WFD. To respond to this legal necessity, we develop a unique, useful and suitable methodology in Walloon Region to determine and schedule river physical quality restoration works. This methodology has been applied on 3 "risk water bodies". The works are based on two axes : longitudinal continuity and transversal continuity. The two first selected water bodies (Bocq river, eastern tributary of the Meuse) seem to be convenient for the restoration works which concern the longitudinal continuity due to the presence of dams and other obstacles usually between 1 and 3 m high. These works consist in dam management (weir removal or fish passage) taking into account hydromorphological (bedload transport) and biological (invertebrate or fish species free movement) impacts. The third water bodies (Eau Blanche river, western tributary of the Meuse) presents straightened rivers with artificial banks, witch consequently own bad connections between the stream and its floodplain. This water bodies should therefore be appropriated for the works based on the transversal continuity recovery. They consist in enhancing straightened river channels, restoring meanders or bank restoration. The first river restoration works will take place from summer 2010. A monitoring has already been undertaken to draw up the situation before the restoration works, witch will be able to compare to the situations during and after works. In addition, a natural site has been chosen to enable any comparison with the intervention sites. The geomorphological monitoring is based on physical and sedimentological parameters (substrate cartography, velocity measures, stream channel DEM, topography and sedimentological index). The ecological monitoring consists in analysing the physical and chemical parameters (turbidity, suspended sediment load). It also analyses the biological quality through 3 indicators: macrophytes, macroinvertebrates and fishes. Among other, a microhabitats method has been improved and applied on 3 intervention sites and 1 natural site. The microhabitats cartography results from both the flow velocity cartography and the substrate cartography. With this method, the physical quality of each intervention site could be compared with the natural site and above all with the future situation. Our method is also useful to inventory precisely invertebrates and to characterise fish habitats.

In 2004, Korea passed legislation that limited the work week to 40 hours, in an effort to improve quality-of-life and increase business competitiveness. This regulation was implemented in stages, first for large businesses and then for small businesses, from 2004 to 2011. We previously reported that average weekly working hours decreased from 2006 to 2010, based on the Korean Working Conditions Survey. In the present study, we examine whether average weekly working hours continued to decrease in 2014 based on the 2014 Korean Working Conditions Survey. The results show that average weekly working hours among all groups of workers decreased in 2014 relative to previous years; however, self-employed individuals and employers (who are not covered by the new legislation) in the specific service sectors worked > 60 h/wk in 2014. The Korean government should prohibit employees from working excessive hours and should also attempt to achieve social and public consensus regarding work time reduction to improve the safety, health, and quality-of-life of all citizens, including those who are employers and self-employed.

The observational cross-sectional study conducted on a sample of 100 women workers who volunteered, outlines their cardio-respiratory and musculo-skeletal profile before, during and at end of work. In addition, information on their health status in general was collected in advance. Contrary to expectation, there was no significant change in respiratory function. However, the musculo-skeletal problems were found to be abundantly present with pain in 91% of the subjects. Region-wise mapping of pain revealed that postural pain in low back was present in 47% while in neck was 19%. Scapular muscles on the right side were involved in stabilizing shoulder, which never went overhead. On the contrary, left shoulder was raised as high (>90 degrees) in spinning action, while pulling thread. This muscle work involved trapezius, deltoid and triceps action concentrically in lifting and while coming to starting position slowly, eccentrically. There was no pause since the wheel continued to spin the thread continuously, unless a worker opted to stop the work. Accordingly, left wrist and hand were in holding contraction while the right wrist and hand holding the handle were also in a fixed position with wrist in flexion with supinated forearm. Though the overall job was light as per peak HR, there was pain due to fatigue and grip strength weakened by around 10%, at the end of the day's work. In conclusion, pain and fatigue were found to be the main problems for women in the spinning section of the small-scale industry under this study. Women have to take up dual responsibility of a full-time job as well as the domestic work. It was considered that ergonomic factors such as provision of a backrest and frequent rest periods could remediate the musculo-skeletal symptoms. PMID:20040992

Implementing Molecular Dynamics on Hybrid High Performance Computers - Particle-Particle Particle-Mesh

DOE Office of Scientific and Technical Information (OSTI.GOV)

Brown, W Michael; Kohlmeyer, Axel; Plimpton, Steven J

The use of accelerators such as graphics processing units (GPUs) has become popular in scientific computing applications due to their low cost, impressive floating-point capabilities, high memory bandwidth, and low electrical power requirements. Hybrid high-performance computers, machines with nodes containing more than one type of floating-point processor (e.g. CPU and GPU), are now becoming more prevalent due to these advantages. In this paper, we present a continuation of previous work implementing algorithms for using accelerators into the LAMMPS molecular dynamics software for distributed memory parallel hybrid machines. In our previous work, we focused on acceleration for short-range models with anmore » approach intended to harness the processing power of both the accelerator and (multi-core) CPUs. To augment the existing implementations, we present an efficient implementation of long-range electrostatic force calculation for molecular dynamics. Specifically, we present an implementation of the particle-particle particle-mesh method based on the work by Harvey and De Fabritiis. We present benchmark results on the Keeneland InfiniBand GPU cluster. We provide a performance comparison of the same kernels compiled with both CUDA and OpenCL. We discuss limitations to parallel efficiency and future directions for improving performance on hybrid or heterogeneous computers.« less

Numerical Modelling of Rayleigh Wave Propagation in Course of Rapid Impulse Compaction

NASA Astrophysics Data System (ADS)

Herbut, Aneta; Rybak, Jarosław

2017-10-01

As the soil improvement technologies are the area of a rapid development, they require designing and implementing novel methods of control and calibration in order to ensure the safety of geotechnical works. At Wroclaw University of Science and Technology (Poland), these new methods are continually developed with the aim to provide the appropriate tools for the preliminary design of work process, as well as for the further ongoing on-site control of geotechnical works (steel sheet piling, pile driving or soil improvement technologies). The studies include preliminary numerical simulations and field tests concerning measurements and continuous histogram recording of shocks and vibrations and its ground-born dynamic impact on engineering structures. The impact of vibrations on reinforced concrete and masonry structures in the close proximity of the construction site may be destroying in both architectural and structural meaning. Those limits are juxtaposed in codes of practice, but always need an individual judgment. The results and observations make it possible to delineate specific modifications to the parameters of technology applied (e.g. hammer drop height). On the basis of numerous case studies of practical applications, already summarized and published, we were able to formulate the guidelines for work on the aforementioned sites. This work presents specific aspects of the active design (calibration of building site numerical model) by means of technology calibration, using the investigation of the impact of vibrations that occur during the Impulse Compaction on adjacent structures. A case study entails the impact of construction works on Rayleigh wave propagation in the zone of 100 m (radius) around the Compactor.
