This invited review on the beneficial effects of nutraceuticals in the gastrointestinal tract reports previous work conducted by the authors as well as the work by other researchers in this expanding field. The text of our article on several occasions reports sentences very similar or identical to those which appear in the manuscript from which the information was obtained and this applies to both our own work and some other researchers' work. This was mainly due to the fact that we tried to maintain unchanged the original meaning of what we reported in our review. Also, it was our intention to give full credit to the authors of manuscripts dealing with the gastrointestinal effects of nutraceuticals and in some instances we preferred to quote the original paper rather than the review where this original information was taken from. We realize that a number (8) of manuscripts, source of the information reported in our review, were not included in the reference list (which contains over 100 references) and we deeply apologize for this with the authors of the missing references. In most of the cases this was due to a mistake in the final editing of the manuscript. In some other cases this was because we tried not to exceed the number of references requested. We therefore, by means of this addendum, would like to add to the reference list taken out the articles which were not quoted in the manuscript at the time it was published. Two of the articles deal with the effect of nutraceuticals in the upper gastrointestinal tract. The remaining six deal with the effect of nutraceuticals in the lower gastrointestinal tract.

Research in many fields could not be done without computers. There is often a great deal of technical data, even in the biological fields, that need to be analyzed. These data, unfortunately, previously absorbed much of every researcher's time. Now, due to the steady increase in computer technology, biological researchers are able to make incredible advances in their work without the added worries of tedious and difficult tasks such as the many mathematical calculations involved in today's research and health care.

Deformity of the breast and axilla observed in famous paintings is a fascinating field for the medico-artists. The attempt of a retrospective diagnosis of breast tumors is highly challenging. This paper deals with a Rubens painting portraying the heroine Judith with a visible but previously unreported left breast mass. Though speculative, the present medico-artistic diagnosis is of a tumor likely to be of benign nature. It is of interest that the present case is the sixth breast disease discovered in Rubens’s works. PMID:27101221

Risk and risk management for Australian sex workers.

PubMed

Harris, Margaret; Nilan, Pam; Kirby, Emma

2011-03-01

In this article, we address the experiences of female sex workers in urban Australia through analysis of interviews using a feminist approach. Although many previous studies have been conducted, our focus was on the voices of sex workers in an area that was rapidly gentrifying, leading to local community tensions. Intensive analysis of interview transcripts was employed to derive thematic codes for understanding how the women viewed and managed everyday risk in sex work. They were well aware of the health risks associated with sex work. For women working on premises, domain separation between sex work and other life domains was an important management strategy for maintaining self-esteem. For women working on the street, instincts honed by years of dangerous work provided a measure of safety. Our findings have implications for health and other agencies dealing with sex workers in situations in which community pressure is exerted to move sex workers away from the area.

An investigation of transitional management problems for the NSTS at NASA, executive summary

NASA Technical Reports Server (NTRS)

Hunsucker, John

1988-01-01

A summary is given of the work of the University of Houston research team for the third quarter of effort in a yearly grant for the National Space Transportation System (NSTS). As such it serves as a resting place for the ideas and concepts developed this quarter with the collaboration of the Management Integration Offices of NASA. Another objective is the hope that the report will help to stimulate the healthy problem solving process already present at NASA. The main goal of the contractual work is to help NASA to find ways and means of moving into a truly operational era with the shuttle program. This work is a continuation of early work and the reader is encouraged to read the final reports of earlier years. Chapter One of the report is an introduction. Chapter Two deals with industrial adaptation and is in two parts: theory and application. In the theory section, impressions of the management system immediately after reflight are discussed. A key issue, in the author's opinion is the seeming lack of purpose of the program. The application section has six appendices: 1988 Demographic Survey, Field Notes of Interview with HL/P South Texas Nuclear Project, a comparison of the Agendas of the current manager with that of a previous manager, a note on compartmentalization to assist in manifesting, a study on launch prediction for STS-26, and a discussion of a statistical decision-making course for upper level managers. Chapter Three deals with theoretical results returned on flow shop scheduling which will be of use downstream. Chapter Four deals with a statistical model developed to predict the flight rate in future years and indicates the program will have trouble making its schedule. Chapter Five covers the constructural effort and shows the work to be on schedule.

Violence prevention in special education schools - an integrated practice?

Pihl, Patricia; Grytnes, Regine; Andersen, Lars Peter S

2018-06-01

Research has shown that employees in special education settings are at high risk for work-related threats and violence. Previous research has not yet been able to identify the essential components of training programs that offer protection from work-related threats and violence. Therefore, the aim of this study was to explore how employees in special education schools deal with prevention of work-related threats and violence. Group interviews were conducted with 14 employees working at 5 special education schools. Results show that employees use a wide range of prevention strategies drawing on specific violence prevention techniques as well as professional pedagogical approaches. We propose that the prevention of threats and violence in special education schools can be understood as an integrated pedagogical practice operating on three interrelated levels.

NASA Astrophysics Data System (ADS)

Kamarian, S.; Shakeri, M.; Yas, M. H.

2017-07-01

Composite plates play a very important role in engineering applications, especially in aerospace industry. Thermal buckling of such components is of great importance and must be known to achieve an appropriate design. This paper deals with stacking sequence optimisation of laminated composite plates for maximising the critical buckling temperature using a powerful meta-heuristic algorithm called firefly algorithm (FA) which is based on the flashing behaviour of fireflies. The main objective of present work was to show the ability of FA in optimisation of composite structures. The performance of FA is compared with the results reported in the previous published works using other algorithms which shows the efficiency of FA in stacking sequence optimisation of laminated composite structures.

The association between long working hours and health: a systematic review of epidemiological evidence.

PubMed

Bannai, Akira; Tamakoshi, Akiko

2014-01-01

Many studies have investigated the association between long working hours and health. By focusing on differences in the definition of long working hours and the influence of shift work, we attempt to explain why the results of these studies remain inconclusive. We defined long working hours as working time greater than around 40 hours per week or 8 hours per day. Since previous studies have indicated that shift work is detrimental to health, we minimized the influence of shift work in the studies. We also placed importance on the existence of reference groups since this made the results clearer. Based on these points, we analyzed previous studies to clarify the epidemiological evidence regarding the association between long working hours and health. We established inclusion criteria and carried out a systematic search for articles published in the Medline and PsycINFO databases between 1995-2012. We identified a total of 17 articles and 19 studies (12 prospective cohort and 7 cross-sectional studies). The outcomes were all-cause mortality, circulatory disease, diabetes mellitus, metabolic syndrome, depressive state, anxiety, other psychological disorders, sleep condition, cognitive function, and health-related behavior. Long working hours had significant adverse effects on most health outcomes. We concluded that working long hours is associated with depressive state, anxiety, sleep condition, and coronary heart disease. However, further studies that appropriately deal with the definition of long working hours and shift work are needed.

An automated method to find reaction mechanisms and solve the kinetics in organometallic catalysis.

Varela, J A; Vázquez, S A; Martínez-Núñez, E

2017-05-01

A novel computational method is proposed in this work for use in discovering reaction mechanisms and solving the kinetics of transition metal-catalyzed reactions. The method does not rely on either chemical intuition or assumed a priori mechanisms, and it works in a fully automated fashion. Its core is a procedure, recently developed by one of the authors, that combines accelerated direct dynamics with an efficient geometry-based post-processing algorithm to find transition states (Martinez-Nunez, E., J. Comput. Chem. 2015 , 36 , 222-234). In the present work, several auxiliary tools have been added to deal with the specific features of transition metal catalytic reactions. As a test case, we chose the cobalt-catalyzed hydroformylation of ethylene because of its well-established mechanism, and the fact that it has already been used in previous automated computational studies. Besides the generally accepted mechanism of Heck and Breslow, several side reactions, such as hydrogenation of the alkene, emerged from our calculations. Additionally, the calculated rate law for the hydroformylation reaction agrees reasonably well with those obtained in previous experimental and theoretical studies.

Hybrid Discrete-Continuous Markov Decision Processes

2003-01-01

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.

In a project funded by the Swedish Civil Contingencies Agency, the effort and work to reduce different kinds of accidents are being evaluated. The project wants to illuminate the links between actions and outcome, so we can learn from today's performance and in the future select more effective measures and overall deal with accidents more efficiently. The project ESS covers the field of frequent accidents such as sliding accidents at home, in house fires and less common accidents such as chemical and land fill accidents up to even more rare accidents such as natural accidents and hazards. In the ESS project SGI (Swedish geotechnical institute) will evaluate the work and effort concerning various natural hazards limited to landslides, erosion and flooding. The aim is to investigate how municipalities handle, especially prevention, of such natural disasters today. The project includes several aspects such as: • which are the driving forces for risk analysis in a municipality • do one use risk mapping (and what type) in municipal risk analysis • which aspects are most important when selecting preventive measures • in which way do one learn from past accidents • and from previous accidents elsewhere, by for example use existing databases • etc There are many aspects that play a role in a well-functioning safety promotion work. The overall goal is to examine present work and activities, highlight what is well functioning and identify weak points. The aim is to find out where more resources are needed and give suggestions for a more efficient security work. This includes identification of the most efficient "tools" in use or needed. Such tools can be education, directives, funding, more easily available maps and information regarding previous accidents and preventive measures etc. The project will result in recommendations for more effective ways to deal with landslides, erosion and flooding. Since different kinds of problems can occur depending on level of authority the investigation of the security work will be done with authorities on both regional and local scale. At the moment the investigation process are in progress and preliminary results will be presented.

Disasters occur more frequently. Acute care providers are the first to respond to mass emergencies from the healthcare sector. The preparedness of acute care providers in New Zealand to respond to mass emergencies has not been previously studied. To assess the self-reported training and experience of New Zealand acute care providers to respond to mass emergencies and the factors associated with strong preparedness. A cross-sectional national survey of 1500 acute care providers in New Zealand carried out between 2009 and 2010. The survey assessed experience, training and self-reported preparedness. It also determined the factors associated with strong perceived preparedness. The response rate to this survey was 60.7%. Nurses had a higher response rate than doctors or paramedics. Only 29.2% of acute care providers reported responding to a previous mass emergency event. There were 53.5% of acute care providers who reported having formal training in how to deal with mass emergencies, whereas 58.1% of participants reported that they were aware of their role during a healthcare mass emergency response. The factors associated with self-reported strong preparedness to deal with mass emergencies included: being a paramedic, previous training, participation in a drill, willingness to report to work during an infection or man-made emergency, ability to triage and general awareness of the role during a mass emergency. Almost half of New Zealand acute healthcare providers have no training in dealing with mass emergency events. Training and general awareness of the role during a mass emergency response were the main factors associated with strong self-reported preparedness of acute care providers. The apparent efficacy of training allied to lack of availability means that it should be a national priority. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Designing worked examples for learning tangent lines to circles

NASA Astrophysics Data System (ADS)

Retnowati, E.; Marissa

2018-03-01

Geometry is a branch of mathematics that deals with shape and space, including the circle. A difficult topic in the circle may be the tangent line to circle. This is considered a complex material since students have to simultaneously apply several principles to solve the problems, these are the property of circle, definition of the tangent, measurement and Pythagorean theorem. This paper discusses designs of worked examples for learning tangent line to circles and how to apply this design to an effective and efficient instructional activity. When students do not have sufficient prior knowledge, solving tangent problems might be clumsy, and as a consequence, the problem-solving activity hinders learning. According to a Cognitive Load Theory, learning occurs when students can construct new knowledge based on the relevant knowledge previously learned. When the relevant knowledge is unavailable, providing students with the worked example is suggested. Worked example may reduce unproductive process during learning that causes extraneous cognitive load. Nevertheless, worked examples must be created in such a way facilitate learning.

How Dutch orthoptists deal with noncompliance with occlusion therapy for amblyopia.

We previously found that compliance with occlusion therapy for amblyopia is poor, especially among children of non-native parents who spoke Dutch poorly and who were low educated. We investigated conception, awareness, attitude, and actions to deal with noncompliance among Dutch orthoptists. Orthoptists working in non-native, low socioeconomic status (SES) areas and a selection of orthoptists working elsewhere in the Netherlands were studied. They were observed in their practice, received a structured questionnaire, and underwent a semi-structured interview. Finally, a short survey was sent to all working orthoptists in the Netherlands. Nine orthoptists working in non-native, low-SES areas and 23 working elsewhere in the Netherlands participated. One hundred and fifty-one orthoptists returned the short survey. Major discrepancies existed in conception, awareness, and attitude. Opinions differed on what should be defined as noncompliance and on what causes noncompliance. Some orthoptists found noncompliance annoying, unpleasant, and hard to imagine, others were more understanding. Many pitied the noncompliant child. Almost all thought that the success of occlusion therapy lies both with the parents and the orthoptist, but one third thought that noncompliance was not solely their responsibility. Patients' compliance was estimated at 69.3% in non-native, low-SES areas (electronically, 52% had been measured), at 74.1% by the other 23 orthoptists, and at 73.8% in the short survey. Actions to improve compliance were diverse; some increased occlusion hours whereas others decreased them. In non-native, low-SES areas, 22% spoke Dutch moderately to none; the allotted time for a patient's first visit was 21'; the time spent on explaining to the parents was 2'30" and to the child 10". In practices of the other 23 orthoptists, 6% spoke Dutch moderately to none (P<0.0001), the time for a patient's first visit was 27'24" (P=0.47), and the periods spent explaining were 2'51" (P=0.59) and 26" (P=0.17), respectively. Conception, awareness, attitude, and actions to deal with noncompliance varied among orthoptists. In non-native, low-SES areas, time spent on explanation was shorter, despite a lower fluency in Dutch among the parents.

1984-07-01

The research during this second contract year continued to deal with the development of sound theoretical models for asynchronous systems. Two criteria served to shape the research pursued: the first, that the developed models extend and generalize previously developed research for synchronous discrete control; the second, that the models explicitly address the question of how to incorporate system transition times into themselves. The following sections of this report concisely delineate this year's work. Our original proposal for this research identified four general tasks of investigation: (1.1) Analysis of Qualitative Properties of Asynchronous Hybrid Systems; (1.2) Acceptance and Control for Asynchronous Hybrid Systems.

An Improved Ensemble Learning Method for Classifying High-Dimensional and Imbalanced Biomedicine Data.

PubMed

Yu, Hualong; Ni, Jun

2014-01-01

Training classifiers on skewed data can be technically challenging tasks, especially if the data is high-dimensional simultaneously, the tasks can become more difficult. In biomedicine field, skewed data type often appears. In this study, we try to deal with this problem by combining asymmetric bagging ensemble classifier (asBagging) that has been presented in previous work and an improved random subspace (RS) generation strategy that is called feature subspace (FSS). Specifically, FSS is a novel method to promote the balance level between accuracy and diversity of base classifiers in asBagging. In view of the strong generalization capability of support vector machine (SVM), we adopt it to be base classifier. Extensive experiments on four benchmark biomedicine data sets indicate that the proposed ensemble learning method outperforms many baseline approaches in terms of Accuracy, F-measure, G-mean and AUC evaluation criterions, thus it can be regarded as an effective and efficient tool to deal with high-dimensional and imbalanced biomedical data.

New Windows based Color Morphological Operators for Biomedical Image Processing

NASA Astrophysics Data System (ADS)

Pastore, Juan; Bouchet, Agustina; Brun, Marcel; Ballarin, Virginia

2016-04-01

Morphological image processing is well known as an efficient methodology for image processing and computer vision. With the wide use of color in many areas, the interest on the color perception and processing has been growing rapidly. Many models have been proposed to extend morphological operators to the field of color images, dealing with some new problems not present previously in the binary and gray level contexts. These solutions usually deal with the lattice structure of the color space, or provide it with total orders, to be able to define basic operators with required properties. In this work we propose a new locally defined ordering, in the context of window based morphological operators, for the definition of erosions-like and dilation-like operators, which provides the same desired properties expected from color morphology, avoiding some of the drawbacks of the prior approaches. Experimental results show that the proposed color operators can be efficiently used for color image processing.

DREAMING THE ANALYTIC SESSION: A CLINICAL ESSAY.

PubMed

Ogden, Thomas H

2017-01-01

This is a clinical paper in which the author describes analytic work in which he dreams the analytic session with three of his patients. He begins with a brief discussion of aspects of analytic theory that make up a good deal of the context for his clinical work. Central among these concepts are (1) the idea that the role of the analyst is to help the patient dream his previously "undreamt" and "interrupted" dreams; and (2) dreaming the analytic session involves engaging in the experience of dreaming the session with the patient and, at the same time, unconsciously (and at times consciously) understanding the dream. The author offers no "technique" for dreaming the analytic session. Each analyst must find his or her own way of dreaming each session with each patient. Dreaming the session is not something one works at; rather, one tries not to get in its way. © 2017 The Psychoanalytic Quarterly, Inc.

A continuum mechanics-based musculo-mechanical model for esophageal transport

NASA Astrophysics Data System (ADS)

Kou, Wenjun; Griffith, Boyce E.; Pandolfino, John E.; Kahrilas, Peter J.; Patankar, Neelesh A.

2017-11-01

In this work, we extend our previous esophageal transport model using an immersed boundary (IB) method with discrete fiber-based structural model, to one using a continuum mechanics-based model that is approximated based on finite elements (IB-FE). To deal with the leakage of flow when the Lagrangian mesh becomes coarser than the fluid mesh, we employ adaptive interaction quadrature points to deal with Lagrangian-Eulerian interaction equations based on a previous work (Griffith and Luo [1]). In particular, we introduce a new anisotropic adaptive interaction quadrature rule. The new rule permits us to vary the interaction quadrature points not only at each time-step and element but also at different orientations per element. This helps to avoid the leakage issue without sacrificing the computational efficiency and accuracy in dealing with the interaction equations. For the material model, we extend our previous fiber-based model to a continuum-based model. We present formulations for general fiber-reinforced material models in the IB-FE framework. The new material model can handle non-linear elasticity and fiber-matrix interactions, and thus permits us to consider more realistic material behavior of biological tissues. To validate our method, we first study a case in which a three-dimensional short tube is dilated. Results on the pressure-displacement relationship and the stress distribution matches very well with those obtained from the implicit FE method. We remark that in our IB-FE case, the three-dimensional tube undergoes a very large deformation and the Lagrangian mesh-size becomes about 6 times of Eulerian mesh-size in the circumferential orientation. To validate the performance of the method in handling fiber-matrix material models, we perform a second study on dilating a long fiber-reinforced tube. Errors are small when we compare numerical solutions with analytical solutions. The technique is then applied to the problem of esophageal transport. We use two fiber-reinforced models for the esophageal tissue: a bi-linear model and an exponential model. We present three cases on esophageal transport that differ in the material model and the muscle fiber architecture. The overall transport features are consistent with those observed from the previous model. We remark that the continuum-based model can handle more realistic and complicated material behavior. This is demonstrated in our third case where a spatially varying fiber architecture is included based on experimental study. We find that this unique muscle fiber architecture could generate a so-called pressure transition zone, which is a luminal pressure pattern that is of clinical interest. This suggests an important role of muscle fiber architecture in esophageal transport.

Street-involved youth are highly vulnerable to violence. While involvement in income-generating activities within illicit drug scenes is recognized as shaping youths' vulnerability to violence, the relative contributions of different income-generating activities remain understudied. We sought to examine the independent effects of drug dealing and sex work on experiencing violence among street-involved youth. Data were derived from a prospective cohort of street-involved youth aged 14-26 who used drugs in Vancouver, British Columbia, between September 2005 and May 2014. Multivariable generalized estimating equations were used to examine the impact of involvement in drug dealing and sex work on experiencing violence. Among 1,152 participants, including 364 (31.6%) women, 740 (64.2%) reported having experienced violence at some point during the study period. In multivariable analysis, involvement in drug dealing but not sex work remained independently associated with experiencing violence among females (adjusted odds ratio [AOR]: 1.43; 95% confidence interval [CI]: 1.08-1.90) and males (AOR: 1.50; 95% CI: 1.25-1.80), while involvement in sex work only was not associated with violence among females (AOR: 1.15; 95% CI: 0.76-1.74) or males (AOR: 1.42; 95% CI: 0.81-2.48). Findings indicate that involvement in drug dealing is a major factor associated with experiencing violence among our sample. In addition to conventional interventions, such as addiction treatment, novel approaches are needed to reduce the risk of violence for drug-using youth who are actively engaged in drug dealing. The potential for low-threshold employment and decriminalization of drug use to mitigate violence warrants further study.

In multivariable analysis, involvement in drug dealing but not sex work remained independently associated with experiencing violence among females (adjusted odds ratio [AOR]: 1.43; 95% confidence interval [CI]: 1.08 – 1.90) and males (AOR: 1.50; 95% CI: 1.25 – 1.80), while involvement in sex work only was not associated with violence among females (AOR: 1.15; 95% CI: 0.76 – 1.74) or males (AOR: 1.42; 95% CI: 0.81 – 2.48). CONCLUSION Findings indicate that involvement in drug dealing is a major factor associated with experiencing violence among our sample. In addition to conventional interventions, such as addiction treatment, novel approaches are needed to reduce the risk of violence for drug-using youth who are actively engaged in drug dealing. The potential for low-threshold employment and decriminalization of drug use to mitigate violence warrants further study. PMID:27348116

Retrieval of total water vapour in the Arctic using microwave humidity sounders

NASA Astrophysics Data System (ADS)

Cristian Scarlat, Raul; Melsheimer, Christian; Heygster, Georg

2018-04-01

Quantitative retrievals of atmospheric water vapour in the Arctic present numerous challenges because of the particular climate characteristics of this area. Here, we attempt to build upon the work of Melsheimer and Heygster (2008) to retrieve total atmospheric water vapour (TWV) in the Arctic from satellite microwave radiometers. While the above-mentioned algorithm deals primarily with the ice-covered central Arctic, with this work we aim to extend the coverage to partially ice-covered and ice-free areas. By using modelled values for the microwave emissivity of the ice-free sea surface, we develop two sub-algorithms using different sets of channels that deal solely with open-ocean areas. The new algorithm extends the spatial coverage of the retrieval throughout the year but especially in the warmer months when higher TWV values are frequent. The high TWV measurements over both sea-ice and open-water surfaces are, however, connected to larger uncertainties as the retrieval values are close to the instrument saturation limits.This approach allows us to apply the algorithm to regions where previously no data were available and ensures a more consistent physical analysis of the satellite measurements by taking into account the contribution of the surface emissivity to the measured signal.

Singlet Oxygen and Free Radical Reactions of Retinoids and Carotenoids—A Review

PubMed Central

Truscott, T. George

2018-01-01

We report on studies of reactions of singlet oxygen with carotenoids and retinoids and a range of free radical studies on carotenoids and retinoids with emphasis on recent work, dietary carotenoids and the role of oxygen in biological processes. Many previous reviews are cited and updated together with new data not previously reviewed. The review does not deal with computational studies but the emphasis is on laboratory-based results. We contrast the ease of study of both singlet oxygen and polyene radical cations compared to neutral radicals. Of particular interest is the switch from anti- to pro-oxidant behavior of a carotenoid with change of oxygen concentration: results for lycopene in a cellular model system show total protection of the human cells studied at zero oxygen concentration, but zero protection at 100% oxygen concentration.

As far as the phenomena of adolescents previously involved with satanism that experience obstacles in the strive for mental health, no research has previously been done. Adolescents previously involved in satanism, presents behaviour problems like aggressive outbursts depression, "psychosis", or suicide attempts that can even lead to suicide. In the phenomena-analysis semi-structured, phenomenological interviews with the respondents and their parents, were performed. The respondents were requested to write a naive sketch about there life. After the data-control was done, guidelines for nursing staff had been set. The guidelines are set for the management of adolescents that has previously been involved in satanism, and experiences obstacles in their strive for mental health. Interviews with experts in satanism was done, literature in the form of books, magazines and newsclippings were used to verify the findings in the research. The most important guidelines are that: the caregivers have to be reborn Christians; they are not allowed to show, any fear or sympathy; they have to have sufficient knowledge about satanism; the adolescent has to be unconditionally accepted; the caregivers have to work in a team; the adolescents have to be taught to deal with their emotions.

Dealing with fear - from the perspective of adolescent girls with cancer.

Anderzén-Carlsson, Agneta; Sörlie, Venke; Kihlgren, Annica

2012-07-01

Previously fears in adolescents with cancer has been identified in relation to medical procedures, death, altered appearance and as having an overall influence on life, but to our knowledge young people's perspectives on dealing with fear have not been previously investigated. To examine adolescents' perspectives on dealing with cancer related fear. Six girls participated in qualitative interviews focussing on their fear and and how they dealt with it. Data were analysed by means of qualitative content analysis. The results revealed two perspectives. First, the adolescents' own personal battle with fear. Second, they reported that they were not alone with their fear, as they shared it with significant others. An environment characterized by emotional presence helped them to deal with their fear, as well as prevented it from occurring. There is a need for staff and parents to be vigilant to the adolescents' need to feel cared for and allow them the opportunity to deal with their own fear, as at times they want to manage in their own way. Young patients have resources to cope with their fears and therefore should not be viewed as victims, but as young people with a great amount of competence, who benefit from a supportive environment.

NASA is considering establishing a policy for the limitation of the physical crowding of the geostationary orbit. The proposed policy is intended to address the following issues: (1) deal only with geostationary altitudes; (2) illustrate the unique value and usefulness of the geostationary orbit ring; (3) describe the orbital dynamics as simply as possible; (4) describe the current spacecraft and debris situation; (5) briefly review current industry and agency policies; (6) project future trends of physical crowding with the present nonpolicy; (7) propose solutions that can be implemented in the near future; and (8) use previous work as much as desirable.

MindDigger: Feature Identification and Opinion Association for Chinese Movie Reviews

NASA Astrophysics Data System (ADS)

Zhao, Lili; Li, Chunping

In this paper, we present a prototype system called MindDigger, which can be used to analyze the opinions in Chinese movie reviews. Different from previous research that employed techniques on product reviews, we focus on Chinese movie reviews, in which opinions are expressed in subtle and varied ways. The system designed in this work aims to extract the opinion expressions and assign them to the corresponding features. The core tasks include feature and opinion extraction, and feature-opinion association. To deal with Chinese effectively, several novel approaches based on syntactic analysis are proposed in this paper. Running results show the performance is satisfactory.

Dealing with uncertainty in modeling intermittent water supply

Lieb, A. M.; Rycroft, C.; Wilkening, J.

2015-12-01

Intermittency in urban water supply affects hundreds of millions of people in cities around the world, impacting water quality and infrastructure. Building on previous work to dynamically model the transient flows in water distribution networks undergoing frequent filling and emptying, we now consider the hydraulic implications of uncertain input data. Water distribution networks undergoing intermittent supply are often poorly mapped, and household metering frequently ranges from patchy to nonexistent. In the face of uncertain pipe material, pipe slope, network connectivity, and outflow, we investigate how uncertainty affects dynamical modeling results. We furthermore identify which parameters exert the greatest influence on uncertainty, helping to prioritize data collection.

Hierarchical Traces for Reduced NSM Memory Requirements

NASA Astrophysics Data System (ADS)

Dahl, Torbjørn S.

This paper presents work on using hierarchical long term memory to reduce the memory requirements of nearest sequence memory (NSM) learning, a previously published, instance-based reinforcement learning algorithm. A hierarchical memory representation reduces the memory requirements by allowing traces to share common sub-sequences. We present moderated mechanisms for estimating discounted future rewards and for dealing with hidden state using hierarchical memory. We also present an experimental analysis of how the sub-sequence length affects the memory compression achieved and show that the reduced memory requirements do not effect the speed of learning. Finally, we analyse and discuss the persistence of the sub-sequences independent of specific trace instances.

Finding text in color images

Zhou, Jiangying; Lopresti, Daniel P.; Tasdizen, Tolga

1998-04-01

In this paper, we consider the problem of locating and extracting text from WWW images. A previous algorithm based on color clustering and connected components analysis works well as long as the color of each character is relatively uniform and the typography is fairly simple. It breaks down quickly, however, when these assumptions are violated. In this paper, we describe more robust techniques for dealing with this challenging problem. We present an improved color clustering algorithm that measures similarity based on both RGB and spatial proximity. Layout analysis is also incorporated to handle more complex typography. THese changes significantly enhance the performance of our text detection procedure.

Optimal non-linear health insurance.

PubMed

Blomqvist, A

1997-06-01

Most theoretical and empirical work on efficient health insurance has been based on models with linear insurance schedules (a constant co-insurance parameter). In this paper, dynamic optimization techniques are used to analyse the properties of optimal non-linear insurance schedules in a model similar to one originally considered by Spence and Zeckhauser (American Economic Review, 1971, 61, 380-387) and reminiscent of those that have been used in the literature on optimal income taxation. The results of a preliminary numerical example suggest that the welfare losses from the implicit subsidy to employer-financed health insurance under US tax law may be a good deal smaller than previously estimated using linear models.

Effects of punishment in a mobile population playing the prisoner's dilemma game

NASA Astrophysics Data System (ADS)

Amor, Daniel R.; Fort, Joaquim

2011-12-01

We deal with a system of prisoner's dilemma players undergoing continuous motion in a two-dimensional plane. In contrast to previous work, we introduce altruistic punishment after the game. We find punishing only a few of the cooperator-defector interactions is enough to lead the system to a cooperative state in environments where otherwise defection would take over the population. This happens even with soft nonsocial punishment (where both cooperators and defectors punish other players, a behavior observed in many human populations). For high enough mobilities or temptations to defect, low rates of social punishment can no longer avoid the breakdown of cooperation.

Russia and the Medical Drug Trade in the Seventeenth Century

PubMed Central

Griffin, Clare

2018-01-01

Summary This article deals with the trade in medicines into Russia in the seventeenth century. Both the early modern medical drug trade, and Russian medicine, have previously received substantial attention, but no work has thus far been undertaken on the Russian angle of the drug trade. Drawing on previously unused documents, this article traces the kinds of drugs acquired by the Moscow court. In contrast to the dominant view of official Russian medicine as divorced from native healing practices and fundamentally reliant upon Western European trends, these documents reveal that drugs were sourced as locally as Moscow markets, and from as far afield as East Asia and the Americas, but that not all drugs were accepted. As many of these imports came through Western European markets, this article also sheds further light on what drugs were available there, demonstrating the great diversity of drugs traded in early modern Europe.

Expanding the role of striatal cholinergic interneurons and the midbrain dopamine system in appetitive instrumental conditioning.

Crossley, Matthew J; Horvitz, Jon C; Balsam, Peter D; Ashby, F Gregory

2016-01-01

The basal ganglia are a collection of subcortical nuclei thought to underlie a wide variety of vertebrate behavior. Although a great deal is known about the functional and physiological properties of the basal ganglia, relatively few models have been formally developed that have been tested against both behavioral and physiological data. Our previous work (Ashby FG, Crossley MJ. J Cogn Neurosci 23: 1549-1566, 2011) showed that a model grounded in the neurobiology of the basal ganglia could account for basic single-neuron recording data, as well as behavioral phenomena such as fast reacquisition that constrain models of conditioning. In this article we show that this same model accounts for a variety of appetitive instrumental conditioning phenomena, including the partial reinforcement extinction (PRE) effect, rapid and slowed reacquisition following extinction, and renewal of previously extinguished instrumental responses by environmental context cues.

The material, moral, and affective worlds of dealing and crime among young men entrenched in an inner city drug scene

Fast, Danya; Shoveller, Jean; Kerr, Thomas

2017-01-01

A large body of previous research has elucidated how involvement in drug dealing and crime among marginalized urban youth who use drugs is shaped by the imperatives of addiction and survival in the context of poverty. However, a growing body of research has examined how youth’s involvement in these activities is shaped by more expansive desires and moralities. In this paper, we examine the material, moral, and affective worlds of loosely gang affiliated, street level dealing and crime among one group of young men in Vancouver, Canada. Drawing on longitudinal interviews with 44 young men from 2008 to 2016, and ethnographic fieldwork with a group of approximately 15 of those young men over the same time period, we argue that for these youth, dealing and crime were not solely about economic survival, or even the accrual of highly meaningful forms of “street capital” in the margins. Rather, as “regimes of living,” dealing and crime also opened up new value systems, moral logics, and affects in relation to the tremendous risks, potential rewards, and crushing boredom of life in the margins. These activities were also understood as a way into deeply desired forms of social spatial belonging in the city, which had previously only been imagined. However, across time dealing and crime ultimately “embedded” young men in cycles of incarceration, destitution, addictions, and mental health crises that ultimately reinforced their exclusion – from legal employment, but also within the world of crime. The findings of this study underscore the importance of adopting a life course perspective in order to meaningfully address the harms associated with involvement in dealing and crime among youth in our setting.

Integrated reflector antenna design and analysis

NASA Technical Reports Server (NTRS)

Zimmerman, M. L.; Lee, S. W.; Ni, S.; Christensen, M.; Wang, Y. M.

1993-01-01

Reflector antenna design is a mature field and most aspects were studied. However, of that most previous work is distinguished by the fact that it is narrow in scope, analyzing only a particular problem under certain conditions. Methods of analysis of this type are not useful for working on real-life problems since they can not handle the many and various types of perturbations of basic antenna design. The idea of an integrated design and analysis is proposed. By broadening the scope of the analysis, it becomes possible to deal with the intricacies attendant with modem reflector antenna design problems. The concept of integrated reflector antenna design is put forward. A number of electromagnetic problems related to reflector antenna design are investigated. Some of these show how tools for reflector antenna design are created. In particular, a method for estimating spillover loss for open-ended waveguide feeds is examined. The problem of calculating and optimizing beam efficiency (an important figure of merit in radiometry applications) is also solved. Other chapters deal with applications of this general analysis. The wide angle scan abilities of reflector antennas is examined and a design is proposed for the ATDRSS triband reflector antenna. The development of a general phased-array pattern computation program is discussed and how the concept of integrated design can be extended to other types of antennas is shown. The conclusions are contained in the final chapter.

Inferring causes during speech perception.

PubMed

Liu, Linda; Jaeger, T Florian

2018-05-01

One of the central challenges in speech perception is the lack of invariance: talkers differ in how they map words onto the speech signal. Previous work has shown that one mechanism by which listeners overcome this variability is adaptation. However, talkers differ in how they pronounce words for a number of reasons, ranging from more permanent, characteristic factors such as having a foreign accent, to more temporary, incidental factors, such as speaking with a pen in the mouth. One challenge for listeners is that the true cause underlying atypical pronunciations is never directly known, and instead must be inferred from (often causally ambiguous) evidence. In three experiments, we investigate whether these inferences underlie speech perception, and how the speech perception system deals with uncertainty about competing causes for atypical pronunciations. We find that adaptation to atypical pronunciations is affected by whether the atypical pronunciations are seen as characteristic or incidental. Furthermore, we find that listeners are able to maintain information about previous causally ambiguous pronunciations that they experience, and use this previously experienced evidence to drive their adaptation after additional evidence has disambiguated the cause. Our findings revise previous proposals that causally ambiguous evidence is ignored during speech adaptation. Copyright © 2018 Elsevier B.V. All rights reserved.

The effects of task and resource interdependence on achievement and social support: an exploratory study of Italian children.

Bertucci, Andrea; Johnson, David W; Johnson, Roger T; Conte, Stella

2011-01-01

The relative efficacy of positive task interdependence, positive resource interdependence, and individualistic learning were compared with achievement and academic and personal social support. The authors randomly assigned to conditions 66 7th-grade Italian students with no previous experience in cooperative learning. They participated in 6 90-min instructional sessions dealing with the dangers of smoking, alcohol, and drugs. The results indicated that students assigned to the task-interdependence and resource-interdependence conditions achieved higher and perceived greater peer academic support than did students working individually. Students in the resource-interdependence condition showed a higher perception of peer personal support than students assigned to the other conditions.

Conformal blocks from Wilson lines with loop corrections

We compute the conformal blocks of the Virasoro minimal model or its WN extension with large central charge from Wilson line networks in a Chern-Simons theory including loop corrections. In our previous work, we offered a prescription to regularize divergences from loops attached to Wilson lines. In this paper, we generalize our method with the prescription by dealing with more general operators for N =3 and apply it to the identity W3 block. We further compute general light-light blocks and heavy-light correlators for N =2 with the Wilson line method and compare the results with known ones obtained using a different prescription. We briefly discuss general W3 blocks.

Characteristics of cesium iodide for use as a particle discriminator for high energy cosmic rays

NASA Technical Reports Server (NTRS)

Crannell, C. J.; Kurz, R. J.; Viehmann, W.

1973-01-01

The possible use of CsI to discriminate between high energy cosmic ray electrons and interacting protons has been investigated. The pulse-shape properties as a function of ionization density, temperature, and spectral response are presented for thallium-activated CsI and as a function of ionization density for sodium-activated CsI. The results are based on previously published data and on corroborative measurements from the present work. Experimental results on the response of CsI to electron-induced electromagnetic cascades and to interacting hadrons are described. Bibliographies of publications dealing with the properties of CsI and with pulse-shape discrimination techniques are presented.

A modified Lorentz theory as a test theory of special relativity

NASA Technical Reports Server (NTRS)

Chang, T.; Torr, D. G.; Gagnon, D. R.

1988-01-01

Attention has been given recently to a modified Lorentz theory (MLT) that is based on the generalized Galilean transformation. Some explicit formulas within the framework of MLT, dealing with the one-way velocity of light, slow-clock transport, and the Doppler effect are derived. A number of typical experiments are analyzed on this basis. Results indicate that the empirical equivalence between MLT and special relativity is still maintained to second order terms. The results of previous works that predict that the MLT might be distinguished from special relativity at the third order by Doppler centrifuge tests capable of a fractional frequency detection threshold of 10 to the -15th are confirmed.

Dynamic Control of Plans with Temporal Uncertainty

NASA Technical Reports Server (NTRS)

Morris, Paul; Muscettola, Nicola; Vidal, Thierry

2001-01-01

Certain planning systems that deal with quantitative time constraints have used an underlying Simple Temporal Problem solver to ensure temporal consistency of plans. However, many applications involve processes of uncertain duration whose timing cannot be controlled by the execution agent. These cases require more complex notions of temporal feasibility. In previous work, various "controllability" properties such as Weak, Strong, and Dynamic Controllability have been defined. The most interesting and useful Controllability property, the Dynamic one, has ironically proved to be the most difficult to analyze. In this paper, we resolve the complexity issue for Dynamic Controllability. Unexpectedly, the problem turns out to be tractable. We also show how to efficiently execute networks whose status has been verified.

In this paper the authors deal with the question of gravitational type interactions in the case of strong interaction phenomena. They present arguments which indicate that it is not necessary to invoke a gravity type interaction into QCD in order to account for observed phenomena. They argue that the gravitational type phenomena discussed in previous work is a manifestation of a class of Feynmann diagrams. These seem to generate an analog to gravity, a J=2 {open_quotes}chromograviton{close_quotes} or {open_quotes}pseudo-graviton{close_quotes} whose action effectively generates Salam`s {open_quotes}Strong Gravity{close_quotes} or {open_quotes}f-gravity{close_quotes}, withthough having to introduce the theory as an additional input.

What do nurses and midwives value about their jobs? Results from a discrete choice experiment.

Scott, Anthony; Witt, Julia; Duffield, Christine; Kalb, Guyonne

2015-01-01

To examine nurses' and midwives' preferences for the characteristics of their jobs. A discrete choice experiment of 990 nurses and midwives administered as part of a survey of nurses and midwives in Victoria, Australia. Autonomy, working hours, and processes to deal with violence and bullying were valued most highly. Nurses and midwives would be willing to forgo 19% and 16% of their annual income for adequate autonomy and adequate processes to deal with violence and bullying, compared to poor autonomy and poor processes for violence and bullying. They would need to be paid an additional 24% to increase their working hours by 10% ($73 per hour). Job characteristics that were less important were shift work, nurse to patient ratios, and public or private sector work. Policies to improve retention and job satisfaction of nurses and midwives should initially focus on autonomy, processes to deal with violence and bullying, and reasonable working hours. Further research on the cost-effectiveness of these different policies is needed. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

[Construction of the work process of the Family Health Support Nucleus: the experience of pharmacists in a city in the south of Brazil].

PubMed

Nakamura, Carina Akemi; Leite, Silvana Nair

2016-05-01

The Family Health Support Nucleus (NASF) was created in 2008 with the objective of broadening the range and scope of primary healthcare. The insertion of pharmacists in this multi-professional context represents an opportunity to enhance the working process and the rational access and use of medicines. The working processes of pharmacists in a city NASF was investigated. Field research was conducted using a qualitative approach with participant observation and semi-structured interviews. Two analytic dialectic categories emerged. The first was the pharmacists' dilemma in the construction of their working process as promoters of primary healthcare, while at the same time facing the need to deal with managerial functions mostly to cater to operational demand. The second was the reality experienced with guidelines and coordination of their work, where pharmacists can be free to structure their work as supporters, although at the same time it limits them due to lack of acknowledgment of their previously established working process. The lack of planning and a clear objective for work in the NASF, besides the deficiency of pharmaceutical services in primary healthcare make the development of any type of pharmacist activity important and essential even if it does not fully attend the NASF proposal.

Methodes entropiques appliquees au probleme inverse en magnetoencephalographie

This thesis is devoted to biomagnetic source localization using magnetoencephalography. This problem is known to have an infinite number of solutions. So methods are required to take into account anatomical and functional information on the solution. The work presented in this thesis uses the maximum entropy on the mean method to constrain the solution. This method originates from statistical mechanics and information theory. This thesis is divided into two main parts containing three chapters each. The first part reviews the magnetoencephalographic inverse problem: the theory needed to understand its context and the hypotheses for simplifying the problem. In the last chapter of this first part, the maximum entropy on the mean method is presented: its origins are explained and also how it is applied to our problem. The second part is the original work of this thesis presenting three articles; one of them already published and two others submitted for publication. In the first article, a biomagnetic source model is developed and applied in a theoretical con text but still demonstrating the efficiency of the method. In the second article, we go one step further towards a realistic modelization of the cerebral activation. The main priors are estimated using the magnetoencephalographic data. This method proved to be very efficient in realistic simulations. In the third article, the previous method is extended to deal with time signals thus exploiting the excellent time resolution offered by magnetoencephalography. Compared with our previous work, the temporal method is applied to real magnetoencephalographic data coming from a somatotopy experience and results agree with previous physiological knowledge about this kind of cognitive process.

The return of robotic devices and humans to the Moon will occur in the near future. Based on our previous experience, surface dust is a major problem requiring a solution: During Apollo landings, extensive locally- induced stirring of the regolith caused dust to be suspended long enough to come into contact with conducting surfaces. Dust behaved like abrasive Velcro: it adhered to everything and attempts to remove it by simply brushing did not remove fines (<10) and resulted in severe abrasion. Lunar fines, because of their electrostatic charging, were relatively difficult to collect in sample bags along with other size range particles. Within hours, seals were broken, samples contaminated, and portions of the samples, especially fines, lost. Because of this difficulty, details on lunar dust are relatively sparse. Obviously, the strategies initially implemented to deal with lunar dust failed. A major technological challenge will be developing a dust mitigation strategy. A currently proposed strategy based increased magnetic susceptibility in lunar fines may not work uniformly well for fines of non-mare, or non-lunar, composition. Based on dust behavior already observed on previous missions, we believe the successful strategy will deal with dust dynamics resulting from interaction between mechanical and electrostatic forces. We are planning test and develop an electrostatically-based device to modulate the electrical potential of conducting surfaces, hence to self clean exposed surfaces while collecting dust samples. It would scan a surface constantly to control its potential, and a plate of the opposite potential. As a first step, an experimental low mass, power, and volume device with complimentary electron and ion guns with specially designed self-cleaning nozzles are being designed for to test our concept and develop a working charging and discharging strategy in the lunar environment. Meanwhile, a laboratory simulation will act as a feasibility study for a laboratory breadboard self-cleaning device based on the use of combined electron or ion beams. The compact device would act as plasma dust sweeper.

There is a larger proportion and number of older adults in the labor force than ever before. Furthermore, older adults in the workforce are working until later ages. Although a great deal of research has examined physical health and well-being of working older adults, less research has focused on cognitive functioning. The purpose of this article is to provide a broad contemporary and multidisciplinary review of the intersection between cognitive functioning, aging, and work as a follow-up to a paper previously written by Fisher et al. (2014). We begin by providing definitions and background about cognitive functioning and how it changes over the life span. Next we discuss theories relevant to the intersection of cognitive functioning and work, including the use-it-or-lose-it hypothesis, the cognitive reserve hypothesis, hypotheses regarding environmental influences on intellectual functioning, and the job-demands-resources model. Then we summarize recent research about the effects of work on cognitive functioning, as well as ways that cognitive functioning may influence work motivation, learning, development, training, and safety. We conclude by emphasizing the importance of person-environment fit, suggesting avenues for future research, and discussing practical implications for the field of occupational health psychology.

'In-between' and other reasonable ways to deal with risk and uncertainty: A review article.

PubMed

Zinn, Jens O

2016-11-16

How people deal with risk and uncertainty has fuelled public and academic debate in recent decades. Researchers have shown that common distinctions between rational and 'irrational' strategies underestimate the complexity of how people approach an uncertain future. I suggested in 2008 that strategies in-between do not follow standards of instrumental rationality nor they are 'irrational' but follow their own logic which works well under particular circumstances. Strategies such as trust, intuition and emotion are an important part of the mix when people deal with risk and uncertainty. In this article, I develop my original argument. It explores in-between strategies to deal with possible undesired outcomes of decisions. I examine 'non-rational strategies' and in particular the notions of active, passive and reflexive hope. Furthermore, I argue that my original typology should be seen as a triangular of reasonable strategies which work well under specific circumstances. Finally, I highlight a number of different ways in which these strategies combine.

Using mediation techniques to manage conflict and create healthy work environments.

Gerardi, Debra

2004-01-01

Healthcare organizations must find ways for managing conflict and developing effective working relationships to create healthy work environments. The effects of unresolved conflict on clinical outcomes, staff retention, and the financial health of the organization lead to many unnecessary costs that divert resources from clinical care. The complexity of delivering critical care services makes conflict resolution difficult. Developing collaborative working relationships helps to manage conflict in complex environments. Working relationships are based on the ability to deal with differences. Dealing with differences requires skill development and techniques for balancing interests and communicating effectively. Techniques used by mediators are effective for resolving disputes and developing working relationships. With practice, these techniques are easily transferable to the clinical setting. Listening for understanding, reframing, elevating the definition of the problem, and forming clear agreements can foster working relationships, decrease the level of conflict, and create healthy work environments that benefit patients and professionals.

Quantum dynamics calculations using symmetrized, orthogonal Weyl-Heisenberg wavelets with a phase space truncation scheme. III. Representations and calculations.

PubMed

Poirier, Bill; Salam, A

2004-07-22

In a previous paper [J. Theo. Comput. Chem. 2, 65 (2003)], one of the authors (B.P.) presented a method for solving the multidimensional Schrodinger equation, using modified Wilson-Daubechies wavelets, and a simple phase space truncation scheme. Unprecedented numerical efficiency was achieved, enabling a ten-dimensional calculation of nearly 600 eigenvalues to be performed using direct matrix diagonalization techniques. In a second paper [J. Chem. Phys. 121, 1690 (2004)], and in this paper, we extend and elaborate upon the previous work in several important ways. The second paper focuses on construction and optimization of the wavelength functions, from theoretical and numerical viewpoints, and also examines their localization. This paper deals with their use in representations and eigenproblem calculations, which are extended to 15-dimensional systems. Even higher dimensionalities are possible using more sophisticated linear algebra techniques. This approach is ideally suited to rovibrational spectroscopy applications, but can be used in any context where differential equations are involved.

Volatility and correlation-based systemic risk measures in the US market

NASA Astrophysics Data System (ADS)

Civitarese, Jamil

2016-10-01

This paper deals with the problem of how to use simple systemic risk measures to assess portfolio risk characteristics. Using three simple examples taken from previous literature, one based on raw and partial correlations, another based on the eigenvalue decomposition of the covariance matrix and the last one based on an eigenvalue entropy, a Granger-causation analysis revealed some of them are not always a good measure of risk in the S&P 500 and in the VIX. The measures selected do not Granger-cause the VIX index in all windows selected; therefore, in the sense of risk as volatility, the indicators are not always suitable. Nevertheless, their results towards returns are similar to previous works that accept them. A deeper analysis has shown that any symmetric measure based on eigenvalue decomposition of correlation matrices, however, is not useful as a measure of "correlation" risk. The empirical counterpart analysis of this proposition stated that negative correlations are usually small and, therefore, do not heavily distort the behavior of the indicator.

The role of high work-function metallic nanodots on the performance of a-Si:H solar cells: offering ohmic contact to light trapping.

Addition of carbon into p-type "window" layers in hydrogenated amorphous silicon (a-Si:H) solar cells enhances short circuit currents and open circuit voltages by a great deal. However, a-Si:H solar cells with high carbon-doped "window" layers exhibit poor fill factors due to a Schottky barrier-like impedance at the interface between a-SiC:H windows and transparent conducting oxides (TCO), although they show maximized short circuit currents and open circuit voltages. The impedance is caused by an increasing mismatch between the work function of TCO and that of p-type a-SiC:H. Applying ultrathin high-work-function metals at the interface between the two materials results in an effective lowering of the work function mismatch and a consequent ohmic behavior. If the metal layer is sufficiently thin, then it forms nanodots rather than a continuous layer which provides light-scattering effect. We demonstrate 31% efficiency enhancement by using high-work-function materials for engineering the work function at the key interfaces to raise fill factors as well as photocurrents. The use of metallic interface layers in this work is a clear contrast to previous work where attempts were made to enhance the photocurrent using plasmonic metal nanodots on the solar cell surface.

The aim of this study was to explore factors that ameliorate work ability by focusing on workers' capacity to deal with stress.The subjects were 1,330 workers from the Japanese information technology (IT) sector. Each subject completed questionnaires in 2011 and 2012 that consisted of the work ability index (WAI), the three-item sense of coherence (SOC), and the Mental Health Improvement and Reinforcement Research of Recognition (MIRROR). The results of the WAI were also obtained in 2013. The median SOC score in 2011 was used to divide the subjects into two groups, the Low SOC group and the High SOC group, then we verified the factors that contributed to improved work ability in both of these groups over a two-year period. Results indicate that an improvement in work ability in the Low SOC group could be predicted by giving workers opportunities for education or training, by making efforts to reduce the stress of commuting, by clarifying their assignments, and by establishing support systems when troubles occur. For the High SOC group, such improvements could be predicted by giving workers job control, by giving education or training for the promotion of their abilities, and by establishing a system for assuming responsibility. In conclusion, improvements in the work environment can increase the work ability of Japanese IT workers in conformity with their capacity to deal with stress.

Sexual harassment at work place: are you safe?

In today's world women are increasingly participating in the realm of work force, yet they are facing many obstacles in their way. Sexual harassment is one of those obstacles. Sexual harassment at work place is prevalent in every society. It could happen to anyone but women are the targeted victims. Sexual harassment is considered as a traumatic event and the victim may end up in having physical and mental sufferings that hinders a person to work effectively. At an organisational level this may result in decrease work effectiveness, decreased work productivity, high absenteeism, high turnover, and low staff morale. Hence there is a need that, organisations and government should look seriously into this matter. Proper education and training programs should be developed to deal with these issues. The goal must be both to deal with sexual harassment incidents effectively and to prevent the occurrence of future incidents.

An oil fraction neural sensor developed using electrical capacitance tomography sensor data.

This paper presents novel research on the development of a generic intelligent oil fraction sensor based on Electrical Capacitance Tomography (ECT) data. An artificial Neural Network (ANN) has been employed as the intelligent system to sense and estimate oil fractions from the cross-sections of two-component flows comprising oil and gas in a pipeline. Previous works only focused on estimating the oil fraction in the pipeline based on fixed ECT sensor parameters. With fixed ECT design sensors, an oil fraction neural sensor can be trained to deal with ECT data based on the particular sensor parameters, hence the neural sensor is not generic. This work focuses on development of a generic neural oil fraction sensor based on training a Multi-Layer Perceptron (MLP) ANN with various ECT sensor parameters. On average, the proposed oil fraction neural sensor has shown to be able to give a mean absolute error of 3.05% for various ECT sensor sizes.

Development of a New Intelligent Joystick for People with Reduced Mobility.

Despite the diversity of electric wheelchairs, many people with physical limitations and seniors have difficulty using their standard joystick. As a result, they cannot meet their needs or ensure safe travel. Recent assistive technologies can help to give them autonomy and independence. This work deals with the real-time implementation of an artificial intelligence device to overcome these problems. Following a review of the literature from previous work, we present the methodology and process for implementing our intelligent control system on an electric wheelchair. The system is based on a neural algorithm that overcomes problems with standard joystick maneuvers such as the inability to move correctly in one direction. However, this implies the need for an appropriate methodology to map the position of the joystick handle. Experiments on a real wheelchair are carried out with real patients of the Mohamed Kassab National Institute Orthopedic, Physical and Functional Rehabilitation Hospital of Tunis. The proposed intelligent system gives good results compared to the use of a standard joystick.

A Moving Mesh Finite Element Algorithm for Singular Problems in Two and Three Space Dimensions

NASA Astrophysics Data System (ADS)

Li, Ruo; Tang, Tao; Zhang, Pingwen

2002-04-01

A framework for adaptive meshes based on the Hamilton-Schoen-Yau theory was proposed by Dvinsky. In a recent work (2001, J. Comput. Phys.170, 562-588), we extended Dvinsky's method to provide an efficient moving mesh algorithm which compared favorably with the previously proposed schemes in terms of simplicity and reliability. In this work, we will further extend the moving mesh methods based on harmonic maps to deal with mesh adaptation in three space dimensions. In obtaining the variational mesh, we will solve an optimization problem with some appropriate constraints, which is in contrast to the traditional method of solving the Euler-Lagrange equation directly. The key idea of this approach is to update the interior and boundary grids simultaneously, rather than considering them separately. Application of the proposed moving mesh scheme is illustrated with some two- and three-dimensional problems with large solution gradients. The numerical experiments show that our methods can accurately resolve detail features of singular problems in 3D.

In the framework of the Soviet law, probation accompanied by compulsory work represents an up-to-date measure of a criminal character that allows to rehabilitate a convicted offender without depriving him of his freedom. The Panfederal Institute for the study of the causes of criminal behaviour and for the formulation of measures for preventing it, has conducted a number of researches directed at clearing up some debated problems bearing on the implementation of the measures existing on the subject, and at collecting proposals of amendment. The present article deals with the assumptions and preconditions, of both an objective and subjective character, underlying the application of this juridical institute, and also tackles, by referring to some cases previously occurred, the problems posed by the various types of subjects. Special attention is devoted to the decision-making procedure followed by the tribunals in applying the said measures, and to the various elements on which it is to be based.

Analysis of wave propagation in a two-dimensional photonic crystal with negative index of refraction: plane wave decomposition of the Bloch modes.

PubMed

Martínez, Alejandro; Míguez, Hernán; Sánchez-Dehesa, José; Martí, Javier

2005-05-30

This work presents a comprehensive analysis of electromagnetic wave propagation inside a two-dimensional photonic crystal in a spectral region in which the crystal behaves as an effective medium to which a negative effective index of refraction can be associated. It is obtained that the main plane wave component of the Bloch mode that propagates inside the photonic crystal has its wave vector k' out of the first Brillouin zone and it is parallel to the Poynting vector ( S' ? k'> 0 ), so light propagation in these composites is different from that reported for left-handed materials despite the fact that negative refraction can take place at the interface between air and both kinds of composites. However, wave coupling at the interfaces is well explained using the reduced wave vector ( k' ) in the first Brillouin zone, which is opposed to the energy flow, and agrees well with previous works dealing with negative refraction in photonic crystals.

Protection from radon exposure at home and at work in the directive 2013/59/Euratom.

PubMed

Bochicchio, F

2014-07-01

In recent years, international organisations involved in radiation protection and public health have produced new guidance, recommendations and requirements aiming better protection from radon exposure. These organisations have often worked in close collaboration in order to facilitate the establishment of harmonised standards. This paper deals with such standards and specifically with the new European Council Directive of 5 December 2013 on basic safety standards for protection against the dangers arising from exposure to ionising radiation (2013/59/Euratom). This new Directive has established a harmonised framework for the protection against ionising radiations, including protection from radon exposure. Requirements for radon in workplace are much more tightening than in previous Directive, and exposures to radon in dwellings are regulated for the first time in a Directive. Radon-related articles of this Directive are presented and discussed in this paper, along with some comparisons with other relevant international standards. © The Author 2014.

Poly(imide-siloxane) segmented copolymer structural adhesives prepared by bulk and solution thermal imidization

The improved properties that have been demonstrated through thermal solution imidization in the case of polyimides and poly(imide-siloxane) segmented copolymers suggests significant potential for application of these new materials. Specifically, the enhancement in solubility, moisture reduction, and processability observed through this solution technique is quite dramatic. Previous work has shown that the presence of low amounts of siloxane does not detract significantly from the lap shear strength of these materials to titanium in the case of bulk thermal imidization synthesis. In addition, the siloxane incorporation results in the added advantage of resistance to hot, wet environments. This added durability is presumably due to the hydrophobic siloxane segments preventing the uptake of water at the critical interphase between the adhesive and the adherend. This paper discusses the extension of this work to the solution imidization synthesis technique recently developed in our laboratory. Results dealing with the absolute bond strengths as well as durability and failure surface analysis will be presented.

The Professional QoL questionnaire and the Disposional Resilience Scale were completed by staff (n=85, 80% response rate) in the Norwegian forensic service for ID offenders. Responses from staff working in institutional settings were compared to those from staff in local community services. Staff in the local community services had higher resilience scores compared to the staff in the institutional setting, (t=2.19; P<0.05). However in the other QoL and resilience domains there were no differences between the staff in the two settings. The greater sense of resilient control among community staff may be a function of both the number of service users they work with and the institutional demands they face. Even though these participants worked with relatively high risk clients, they did not report significantly impaired quality of life compared to other occupations.

Staff in forensic services for people with intellectual disabilities (ID) are expected to deal with a wide range of emotional challenges when providing care. The potential impact of this demanding work has not been systematically explored previously. This article explores the professional quality of life (QoL) and the resilience (hardiness) of the staff in this setting. The Professional QoL questionnaire and the Disposional Resilience Scale were completed by staff (n=85, 80% response rate) in the Norwegian forensic service for ID offenders. Responses from staff working in institutional settings were compared to those from staff in local community services. Staff in the local community services had higher resilience scores compared to the staff in the institutional setting, (t=2.19; P<0.05). However in the other QoL and resilience domains there were no differences between the staff in the two settings. The greater sense of resilient control among community staff may be a function of both the number of service users they work with and the institutional demands they face. Even though these participants worked with relatively high risk clients, they did not report significantly impaired quality of life compared to other occupations. PMID:26973892

Teachers as journalists?

NASA Astrophysics Data System (ADS)

Reiss, M.

2011-06-01

I start by considering some of the similarities between journalists and science teachers in their work and then go on to examine three questions that are of importance in dealing with creationism in schools: Is the issue one that is worth dealing with? How might one deal with it? What does one hope to achieve by dealing with it? I conclude that (1) it is worth science teachers dealing with the issue of creationism in schools but only if they wish to; (2) science teachers should not give the impression that the theory of evolution is scientifically controversial; (3) while one is very unlikely to change the mind, as a result of school teaching, of someone who does not, on religious grounds, accept the theory of evolution, it is very worth presenting the scientific account of the theory and enabling students to review the evidence for it.

Street-involved youth are known to be an economically vulnerable population that commonly resorts to risky activities such as drug dealing to generate income. While incarceration is common among people who use illicit drugs and associated with increased economic vulnerability, interventions among this population remain inadequate. Although previous research has documented the role of incarceration in further entrenching youth in both the criminal justice system and street life, less is known whether recent incarceration predicts initiating drug dealing among vulnerable youth. This study examines the relationship between incarceration and drug dealing initiation among street-involved youth. Between September 2005 and November 2014, data were collected through the At-Risk Youth Study, a cohort of street-involved youth who use illicit drugs, in Vancouver, Canada. An extended Cox model with time-dependent variables was used to examine the relationship between recent incarceration and initiation into drug dealing, controlling for relevant confounders. Among 1172 youth enrolled, only 194 (16.6%) were drug dealing naïve at baseline and completed at least one additional study visit to facilitate the assessment of drug dealing initiation. Among this sample, 56 (29%) subsequently initiated drug dealing. In final multivariable Cox regression analysis, recent incarceration was significantly associated with initiating drug dealing (adjusted hazard ratio = 2.31; 95% confidence interval (CI) 1.21-4.42), after adjusting for potential confounders. Measures of recent incarceration lagged to the prior study follow-up were not found to predict initiation of drug dealing (hazard ratio = 1.50; 95% CI 0.66-3.42). These findings suggest that among this study sample, incarceration does not appear to significantly propel youth to initiate drug dealing. However, the initiation of drug dealing among youth coincides with an increased risk of incarceration and their consequent vulnerability to the significant harms associated therein. Given that existing services tailored to street-involved youth are inadequate, evidence-based interventions should be invested and scaled up as a public health priority.

Taking 'women's work' 'like a man': husbands' experiences of care work.

PubMed

Calasanti, Toni; King, Neal

2007-08-01

We adopted a feminist, structural approach to husbands' experiences of caring for wives with Alzheimer's disease. This framework posited that men and women draw upon gender repertoires-situational ideals of behavior based upon their respective structural locations-that create gendered experiences of stress and coping strategies. We used a qualitative, constructivist approach to analyze in-depth interviews with 22 spousal caregivers and observations within support groups. Our analysis focused on the nine husbands, the strategies these men reported using to deal with problems that arose in their care work, and the extent to which these are congruent with the masculinities of White men in the United States. We found that these husbands' approaches to caregiving and their strategies for dealing with the work and feelings involved were rooted in their sense of selves as men. We outline their overall approaches to caregiving, identify six strategies husbands used to deal with problems stemming from care work-exerting force, focusing on tasks, blocking emotions, minimizing disruption, distracting attention, and self-medicating-and tie these to their structural positions as working-, middle-, and professional-class men. Theories of gender differences in the performance or quality of care work should tie these to structural arrangements. Unless the gendered bases upon which different styles or experiences are removed (i.e., structural inequality), designers of interventions cannot and should not expect to use the experience of one group to inform appropriate strategies for the other.

Modelling the performance of the monogroove with screen heat pipe for use in the radiator of the solar dynamic power system of the NASA Space Station

1987-01-01

A computer code to model the steady-state performance of a monogroove heat pipe for the NASA Space Station is presented, including the effects on heat pipe performance of a screen in the evaporator section which deals with transient surges in the heat input. Errors in a previous code have been corrected, and the new code adds additional loss terms in order to model several different working fluids. Good agreement with existing performance curves is obtained. From a preliminary evaluation of several of the radiator design parameters it is found that an optimum fin width could be achieved but that structural considerations limit the thickness of the fin to a value above optimum.

Dynamical computation of constrained flexible systems using a modal Udwadia-Kalaba formulation: Application to musical instruments.

PubMed

Antunes, J; Debut, V

2017-02-01

Most musical instruments consist of dynamical subsystems connected at a number of constraining points through which energy flows. For physical sound synthesis, one important difficulty deals with enforcing these coupling constraints. While standard techniques include the use of Lagrange multipliers or penalty methods, in this paper, a different approach is explored, the Udwadia-Kalaba (U-K) formulation, which is rooted on analytical dynamics but avoids the use of Lagrange multipliers. This general and elegant formulation has been nearly exclusively used for conceptual systems of discrete masses or articulated rigid bodies, namely, in robotics. However its natural extension to deal with continuous flexible systems is surprisingly absent from the literature. Here, such a modeling strategy is developed and the potential of combining the U-K equation for constrained systems with the modal description is shown, in particular, to simulate musical instruments. Objectives are twofold: (1) Develop the U-K equation for constrained flexible systems with subsystems modelled through unconstrained modes; and (2) apply this framework to compute string/body coupled dynamics. This example complements previous work [Debut, Antunes, Marques, and Carvalho, Appl. Acoust. 108, 3-18 (2016)] on guitar modeling using penalty methods. Simulations show that the proposed technique provides similar results with a significant improvement in computational efficiency.

Job demands-resources predicting burnout and work engagement among Belgian home health care nurses: A cross-sectional study.

A better knowledge of the job aspects that may predict home health care nurses' burnout and work engagement is important in view of stress prevention and health promotion. The Job Demands-Resources model predicts that job demands and resources relate to burnout and work engagement but has not previously been tested in the specific context of home health care nursing. The present study offers a comprehensive test of the Job-Demands Resources model in home health care nursing. We investigate the main and interaction effects of distinctive job demands (workload, emotional demands and aggression) and resources (autonomy, social support and learning opportunities) on burnout and work engagement. Analyses were conducted using cross-sectional data from 675 Belgian home health care nurses, who participated in a voluntary and anonymous survey. The results show that workload and emotional demands were positively associated with burnout, whereas aggression was unrelated to burnout. All job resources were associated with higher levels of work engagement and lower levels of burnout. In addition, social support buffered the positive relationship between workload and burnout. Home health care organizations should invest in dealing with workload and emotional demands and stimulating the job resources under study to reduce the risk of burnout and increase their nurses' work engagement.

Lopez, Karen Dunn; Cary, Michael P; Kanak, Mary F

2010-01-01

Objective To identify factors in the nursing work domain that contribute to the problem of inpatient falls, aside from patient risk, using cognitive work analysis. Design A mix of qualitative and quantitative methods were used to identify work constraints imposed on nurses, which may underlie patient falls. Measurements Data collection was done on a neurology unit staffed by 27 registered nurses and utilized field observations, focus groups, time–motion studies and written surveys (AHRQ Hospital Survey on Patient Culture, NASA-TLX, and custom Nursing Knowledge of Fall Prevention Subscale). Results Four major constraints were identified that inhibit nurses' ability to prevent patient falls. All constraints relate to work processes and the physical work environment, opposed to safety culture or nursing knowledge, as currently emphasized. The constraints were: cognitive ‘head data’, temporal workload, inconsistencies in written and verbal transfer of patient data, and limitations in the physical environment. To deal with these constraints, the nurses tend to employ four workarounds: written and mental chunking schemas, bed alarms, informal querying of the previous care nurse, and informal video and audio surveillance. These workarounds reflect systemic design flaws and may only be minimally effective in decreasing risk to patients. Conclusion Cognitive engineering techniques helped identify seemingly hidden constraints in the work domain that impact the problem of patient falls. System redesign strategies aimed at improving work processes and environmental limitations hold promise for decreasing the incidence of falls in inpatient nursing units. PMID:20442150

Spurious but systematic correlations in functional connectivity MRI networks arise from subject motion

PubMed Central

Power, Jonathan D; Barnes, Kelly A; Snyder, Abraham Z; Schlaggar, Bradley L; Petersen, Steven E

2011-01-01

Here, we demonstrate that subject motion produces substantial changes in the timecourses of resting state functional connectivity MRI (rs-fcMRI) data despite compensatory spatial registration and regression of motion estimates from the data. These changes cause systematic but spurious correlation structures throughout the brain. Specifically, many long-distance correlations are decreased by subject motion, whereas many short-distance correlations are increased. These changes in rs-fcMRI correlations do not arise from, nor are they adequately countered by, some common functional connectivity processing steps. Two indices of data quality are proposed, and a simple method to reduce motion-related effects in rs-fcMRI analyses is demonstrated that should be flexibly implementable across a variety of software platforms. We demonstrate how application of this technique impacts our own data, modifying previous conclusions about brain development. These results suggest the need for greater care in dealing with subject motion, and the need to critically revisit previous rs-fcMRI work that may not have adequately controlled for effects of transient subject movements.

Current Perspectives on Therapy Dog Welfare in Animal-Assisted Interventions.

PubMed

Glenk, Lisa Maria

2017-02-01

Research into the effects of animal-assisted interventions (AAIs) has primarily addressed human health outcomes. In contrast, only few publications deal with the therapy dog experience of AAIs. This paper provides an overview on potential welfare threats that therapy dogs may encounter and presents the results of a review of available studies on welfare indicators for therapy dogs during AAIs. Previous investigations used physiological and behavioral welfare indicators and dog handler surveys to identify work-related stress. Research outcomes are discussed in the light of strengths and weaknesses of the methods used. Study results suggest that frequency and duration of AAI sessions, novelty of the environment, controllability, age and familiarity of recipients modulate animal welfare indicators. However, this review reveals that currently, clear conclusions on how the well-being of dogs is influenced by the performance in AAIs are lacking due to the heterogeneity of programs, recipient and session characteristics, small dog sample sizes and methodological limitations. This paper further aimed to identify unresolved difficulties in previous research to pave the way for future investigations supporting the applicability of scientific findings in practice.

A new symmetrical quasi-classical model for electronically non-adiabatic processes: Application to the case of weak non-adiabatic coupling

Previous work has shown how a symmetrical quasi-classical (SQC) windowing procedure can be used to quantize the initial and final electronic degrees of freedom in the Meyer-Miller (MM) classical vibronic (i.e, nuclear + electronic) Hamiltonian, and that the approach provides a very good description of electronically non-adiabatic processes within a standard classical molecular dynamics framework for a number of benchmark problems. This study explores application of the SQC/MM approach to the case of very weak non-adiabatic coupling between the electronic states, showing (as anticipated) how the standard SQC/MM approach used to date fails in this limit, and then devises amore » new SQC windowing scheme to deal with it. Finally, application of this new SQC model to a variety of realistic benchmark systems shows that the new model not only treats the weak coupling case extremely well, but it is also seen to describe the “normal” regime (of electronic transition probabilities ≳ 0.1) even more accurately than the previous “standard” model.« less

Pluralism as Outcome: The Ecology of Religious Resources, Suppliers, and Consumers

PubMed Central

Scheitle, Christopher P.; Finke, Roger

2014-01-01

A great deal of interest has surrounded the topic of religious pluralism and the effects of the frequently used pluralism index on outcomes such as religious participation rates. But surprisingly little work has tried to understand the sources of pluralism or what the pluralism index is actually measuring. In an attempt to reframe the debate, we treat pluralism as an outcome variable. Drawing on ideas in the organizational ecology literature and data from previous studies on pluralism and participation, we show that the pluralism of religious suppliers is a product of the pluralism of religious preferences and the number of potential adherents within an environment. This pluralism of suppliers, in turn, produces a pluralism of religious consumers. We then distinguish between expected pluralism and observed pluralism, and we argue that a relationship between pluralism and participation will be expected only when a meaningful gap between these two measures exists. We close by examining the previous research to show how this reframing of the pluralism and participation question sheds light on that literature. PMID:25750598

Robust automatic line scratch detection in films.

PubMed

Newson, Alasdair; Almansa, Andrés; Gousseau, Yann; Pérez, Patrick

2014-03-01

Line scratch detection in old films is a particularly challenging problem due to the variable spatiotemporal characteristics of this defect. Some of the main problems include sensitivity to noise and texture, and false detections due to thin vertical structures belonging to the scene. We propose a robust and automatic algorithm for frame-by-frame line scratch detection in old films, as well as a temporal algorithm for the filtering of false detections. In the frame-by-frame algorithm, we relax some of the hypotheses used in previous algorithms in order to detect a wider variety of scratches. This step's robustness and lack of external parameters is ensured by the combined use of an a contrario methodology and local statistical estimation. In this manner, over-detection in textured or cluttered areas is greatly reduced. The temporal filtering algorithm eliminates false detections due to thin vertical structures by exploiting the coherence of their motion with that of the underlying scene. Experiments demonstrate the ability of the resulting detection procedure to deal with difficult situations, in particular in the presence of noise, texture, and slanted or partial scratches. Comparisons show significant advantages over previous work.

Final Report - Few-Body Studies Using Electromagnetic Interactions

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

Norum, Blaine

The work discussed here is an extension of work previously funded by U.S. Department of Energy Grant DE-FG02-97ER41025. Measurements of charged pion photoproduction from deuterium using the Laser Electron Gamma Source (LEGS) at the Brookhaven National Laboratory previously made by us, as members of the LEGS Collaboration, resulted in the most interesting result of two decades of work. By measuring the production of a charged pion (π +) in coincidence with an emitted photon we observed structures in the residual two-nucleon system. These indicated the existence of rare, long-lived states not explicable by standard nuclear theory; they suggested a setmore » of configurations not explicable in terms of a nucleon-nucleon pair. The existence of such “exotic” structures has formed the foundation for most of the work that has ensued. Several measurements at various laboratories have supported, but not proved, the existence of these exotic states. The rarity of these states made their existence undetectable in most previous measurements. Only by observing characteristic signatures of such states (i.e., decay photons), by using very specific kinematics which isolate certain reaction products, or by measuring polarization-dependent observables. During the period of this grant we pursued and made progress on the development of experiments to be performed at the High Intensity Gamma Source (HIGS) of the Tri Universities Nuclear Laboratory (TUNL). Our understanding of photon- and electron-induced nuclear reactions depends on understanding of the basic electron and photon interaction. Recently, the issue of two-photon contributions has arisen in the context of deeply inelastic electron scattering. One way to address this is to measure asymmetries in the Bethe-Heitler ee process. We also made progress in developing the detectors required to measure these asymmetries at HIGS. During the last several years the apparent discrepancy between the size of the proton as measured using electrons and that as measured using muons has received a great deal of attention. Working with colleagues at the Jefferson Laboratory (JLAB) we showed that the apparent discrepancy was almost surely the result of mistakes in the statistical analysis of electron scattering data, that there is almost surely no discrepancy.« less

Global Failure Modes in Composite Structures for High Altitudes

Knauss, W. G.

2004-01-01

This report summarizes the accomplishments under the referenced grant. The work described was started under the guidance and supervision of the late Dr. James Stames as the technical contact. It was aimed at investigating the development of analysis tools to deal with the problem of rupture in reinforced structural skin of future composites-based aircraft. It was of particular interest to assess methods by which failure features reminiscent of cracks in metallic structures would develop and propagate in fiber reinforced structures in interaction with the reinforcing frame. To eventually achieve that goal it was necessary to first understand the stress or strain distribution at the front of such features so that interactions between such features and reinforcing agents could be assessed computationally. Thus the major emphasis here was on the assessment of damage front and methods on how to assess or characterize it. During the conduct of this research program Dr. Stames changed to a different NASA- internal assignment, which divorced him of the direct supervision of this grant. A student who was approximately % into the completion of his Ph.D. research needed to finish this work, and NASA funds were made available under Dr. Damodar Ambur, the successor Branch Manager for Dr. James Starnes, for the completion of this work. The current grant was the thus a new and fmal support increment for completion of the started research. Final reports for previous funding have been completed and submitted. Because of the interconnection of this last phase of the investigation with previous work it is deemed useful to make the Ph.D. thesis by Luis Gonzales the body of this report.

S1 deals with physical acoustics, S2 deals with shock and vibration, S3 deals with physiological and psychological acoustics, and S12 deals with noise. ASACOS is the ASA Committee on Standards. The program has three primary tasks: (1) the development of National Standards (ANSI Standards), (2) the national adoption of an international standard (ANSI NAIS Standards), (3) providing the USA input to the development of International Standards (ISO and IEC Standards). At every level the main work is accomplished in Working Groups (WG) that are ''staffed'' by hundreds of volunteers--mainly ASA members from its various technical committees such as Noise, Physical Acoustics, Architectural Acoustics, Psychological and Physiological Acoustics, etc. Overall, the Standards Program involves more ASA members than does any other single function of the Society except meetings and it is the biggest outreach function of ASA affecting the health, welfare, and economic well-being of large segments of the population, the business and industrial community, and government at all levels.

Struggling to adapt: caring for older persons while under threat of organizational change and termination notice.

2009-03-01

Organizational changes are common in elder care today. Such changes affect caregivers, who are essential to providing good quality care. The aim of the present study was to illuminate caregivers' experiences of working in elder care while under threat of organizational change and termination notice. Qualitative content analysis was used to examine interview data from 11 caregivers. Interviews were conducted at three occasions during a two-year period. The findings show a transition in their experiences from 'having a professional identity and self-confidence', to 'being a professional in a threatening situation caused by someone else' and to 'struggling to adapt to a changed working environment as a person and a professional'. The caregivers experienced a loss of pride and satisfaction. Previous literature indicates that this may have consequences for the quality of care and that employees may be at risk of negative health effects. However, the caregivers continued to struggle, doing their best to complete their duties. The study has implications for high-level decision-makers, managers and caregivers in similar work-life situations in that it deals with factors that facilitate or impede similar transitions.

Apart from the problems shared with photonics in education in general, biophotonics specifically needs an interdisciplinary approach between biomedical and technical or scientific fields. In this work, we present our education experience in teaching the subject Fundamentals of Biophotonics, intended preferentially to engineering Bachelor and Master degrees students, but also to science and medicine students. First it was necessary to join a teaching group coming from the scientific technical and medical fields, working together in the subject. This task was easier as our research group, the Applied Optical Techniques group, had previous contacts and experience in working with medicine professors and medical doctors at hospitals. The orientation of the subject, intended for both technical and medical students, has to be carefully selected. All this information could be employed by other education institutions willing to implement studies on biomedical optics.

Biologically inspired information theory: Adaptation through construction of external reality models by living systems.

PubMed

Nakajima, Toshiyuki

2015-12-01

Higher animals act in the world using their external reality models to cope with the uncertain environment. Organisms that have not developed such information-processing organs may also have external reality models built in the form of their biochemical, physiological, and behavioral structures, acquired by natural selection through successful models constructed internally. Organisms subject to illusions would fail to survive in the material universe. How can organisms, or living systems in general, determine the external reality from within? This paper starts with a phenomenological model, in which the self constitutes a reality model developed through the mental processing of phenomena. Then, the it-from-bit concept is formalized using a simple mathematical model. For this formalization, my previous work on an algorithmic process is employed to constitute symbols referring to the external reality, called the inverse causality, with additional improvements to the previous work. Finally, as an extension of this model, the cognizers system model is employed to describe the self as one of many material entities in a world, each of which acts as a subject by responding to the surrounding entities. This model is used to propose a conceptual framework of information theory that can deal with both the qualitative (semantic) and quantitative aspects of the information involved in biological processes.

Physical Premium Principle: A New Way for Insurance Pricing

NASA Astrophysics Data System (ADS)

Darooneh, Amir H.

2005-03-01

In our previous work we suggested a way for computing the non-life insurance premium. The probable surplus of the insurer company assumed to be distributed according to the canonical ensemble theory. The Esscher premium principle appeared as its special case. The difference between our method and traditional principles for premium calculation was shown by simulation. Here we construct a theoretical foundation for the main assumption in our method, in this respect we present a new (physical) definition for the economic equilibrium. This approach let us to apply the maximum entropy principle in the economic systems. We also extend our method to deal with the problem of premium calculation for correlated risk categories. Like the Buhlman economic premium principle our method considers the effect of the market on the premium but in a different way.

Comparison between Smoluchowski and Boltzmann approaches for self-propelled rods.

PubMed

Bertin, Eric; Baskaran, Aparna; Chaté, Hugues; Marchetti, M Cristina

2015-10-01

Considering systems of self-propelled polar particles with nematic interactions ("rods"), we compare the continuum equations describing the evolution of polar and nematic order parameters, derived either from Smoluchowski or Boltzmann equations. Our main goal is to understand the discrepancies between the continuum equations obtained so far in both frameworks. We first show that, in the simple case of point-like particles with only alignment interactions, the continuum equations obtained have the same structure in both cases. We further study, in the Smoluchowski framework, the case where an interaction force is added on top of the aligning torque. This clarifies the origin of the additional terms obtained in previous works. Our observations lead us to emphasize the need for a more involved closure scheme than the standard normal form of the distribution when dealing with active systems.

Enhanced photocurrent in engineered bacteriorhodopsin monolayer.

PubMed

Patil, Amol V; Premaruban, Thenhuan; Berthoumieu, Olivia; Watts, Anthony; Davis, Jason J

2012-01-12

The integration of the transmembrane protein bacteriorhodopsin (BR) with man-made electrode surfaces has attracted a great deal of interest for some two decades or more and holds significant promise from the perspective of derived photoresponse or energy capture interfaces. Here we demonstrate that a novel and strategically engineered cysteine site (M163C) can be used to intimately and effectively couple delipidated BR to supporting metallic electrode surfaces. By virtue of the combined effects of the greater surface molecular density afforded by delipidation, and the vicinity of the electrostatic changes associated with proton pumping to the transducing metallic continuum, the resulting films generate a considerably greater photocurrent density on wavelength-selective illumination than previously achievable with monolayers of BR. Given the uniquely photoresponsive, wavelength-selective, and photostable characteristics of this protein, the work has implications for utilization in solar energy capture and photodetector devices.

Environmental geology in the United States: Present practice and future training needs

NASA Astrophysics Data System (ADS)

Lundgren, Lawrence

Environmental geology as practiced in the United States confronts issues in three large areas: Threats to human society from geologic phenomena (geologic hazards); impacts of human activities on natural systems (environmental impact), and natural-resource management. This paper illustrates present U.S. practice in environmental geology by sampling the work of 7 of the 50 state geological surveys and of the United States Geological Survey as well. Study of the work of these agencies provides a basis for identifying avenues for the training of those who will deal with environmental issues in the future. This training must deal not only with the subdisciplines of geology but with education to cope with the ethical, interdisciplinary, and public-communication aspects of the work of the environmental geologist.

2017-10-01

Supportive interventions to enhance return to work (RTW) in cancer survivors hardly showed positive effects so far. Behavioral determinants might have to be considered in the development of interventions to achieve sustained employability. This study aimed to explore cancer survivors' perspectives and experiences regarding behavioral determinants of RTW and continuation of work. In this qualitative study, semi-structured telephone interviews were held with 28 cancer survivors. All participants were at working age, 1-2 years after diagnosis and employed at time of diagnosis. Thematic content analysis was performed. Work turned out to be a meaningful aspect of cancer survivors' life, and most participants reported a positive attitude towards their job. Social support to RTW or to continue working was mainly received from family and friends, but pressure to RTW from the occupational physician was also experienced. Changes in expectations regarding work ability from negative to positive during the treatment process were observed. Those who applied active coping mechanisms felt equipped to deal with difficulties regarding work. Behavioral determinants should be taken into account in the development of future interventions to support cancer survivors' RTW. However, the causal relationship still has to be determined. Implications for rehabilitation Factors influencing occupational motivation among cancer survivors need to be understood in more detail. Previous studies in non-cancer populations have demonstrated that behavioral determinants, such as a positive attitude towards work, high social support and self-efficacy may increase return to work rates or shorten the time to return to work. Addressing behavioral determinants in future development of work-related interventions for cancer survivors is essential in achieving sustained employability.

Country differences of psychosocial working conditions in Europe: the role of health and safety management practices.

Lunau, Thorsten; Dragano, Nico; Siegrist, Johannes; Wahrendorf, Morten

2017-10-01

In times of demographic change, maintaining health and employability of older employees is important. In this context, studies show that stressful working conditions differ by countries. Yet, it is unclear if specific national management practices to deal with these conditions contribute towards explaining country differences. This study combines two different data sources. The first one provides detailed information on psychosocial working conditions in 17 European countries, based on 12,284 employees from the Survey of Health, Ageing and Retirement in Europe (SHARE) and the English Longitudinal Study of Ageing (ELSA). We link this information to the second data source that provides information on health and safety management practices in each of the countries under study (collected among 17,477 managers at the level of companies in the Enterprise survey on new and emerging risks (ESENER)). We distinguish six different types of risk management procedures in the analysis. Results show that levels of psychosocial risks are generally lower in countries with more developed management practices, in particular if national management practices are marked by (1) procedures to deal with work stress, (2) information about whom to address in case of work-related psychosocial problems, and (3) health and safety services provided by psychologists. The findings underline the importance of a comprehensive psychosocial risk management approach in reducing work-related stress, as lower levels of psychosocial risks are linked to specific psychosocial risk management practices within companies, in particular those pointing to clear responsibilities and coordinated procedures in dealing with psychosocial risks.

A new definition of burnout syndrome based on Farber's proposal

PubMed Central

2009-01-01

Background Although diverse definitions have been construed for burnout syndrome, most authors consider it to be a single phenomenon, the result of chronic work-related stress. However, in order to enable specific intervention strategies to be adopted, it is first necessary to establish different profiles for the syndrome. In this respect, have been proposed three burnout types ("frenetic", "underchallenged" and "worn-out"), each of which requires different means of dealing with frustration in the workplace. This study is an attempt to define and systematize the properties that characterize this typology proposal. Methods For this purpose, the documents considering preliminary typology were examined by means of qualitative content analysis supported by grounded theory. Semiotic analysis was then performed on the core category resulting from the previous analysis. Results A classification criterion, made up of three different burnout subtypes ("frenetic", "underchallenged", and "worn-out") capable of integrating the entire proposal was formulated. Discussion Understanding the development of burnout syndrome, as a succession of stages characterized by the progressive diminishing of dedication to work, could serve for the establishment of specific therapies and for the prevention of the syndrome.

Analysis of the acceptance of autonomous planetary science data collection by field of inquiry

NASA Astrophysics Data System (ADS)

Straub, Jeremy

2015-06-01

The acceptance of autonomous control technologies in planetary science has met significant resistance. Many within this scientific community question the efficacy of autonomous technologies for making decisions regarding what data to collect, how to process it and its processing. These technologies, however, can be used to significantly increase the scientific return on mission investment by removing limitations imposed by communications bandwidth constraints and communications and human decision making delays. A fully autonomous mission, in an ideal case, could be deployed, perform most of the substantive work itself (possibly relying on human assistance for dealing with any unexpected or unexplained occurrences) and return an answer to a scientific question along with data selected to allow scientists to validate software performance. This paper presents the results of a survey of planetary scientists which attempts to identify the root causes of the impediments to the use of this type of technology and identify pathways to its acceptance. Previous work considered planetary science as a single large community. This paper contrasts the differences in acceptance between component fields of planetary science.

The work deals with the application of neural networks residual kriging (NNRK) to the spatial prediction of the abnormally distributed soil pollutant (Cr). It is known that combination of geostatistical interpolation approaches (kriging) and neural networks leads to significantly better prediction accuracy and productivity. Generalized regression neural networks and multilayer perceptrons are classes of neural networks widely used for the continuous function mapping. Each network has its own pros and cons; however both demonstrated fast training and good mapping possibilities. In the work, we examined and compared two combined techniques: generalized regression neural network residual kriging (GRNNRK) and multilayer perceptron residual kriging (MLPRK). The case study is based on the real data sets on surface contamination by chromium at a particular location of the subarctic Novy Urengoy, Russia, obtained during the previously conducted screening. The proposed models have been built, implemented and validated using ArcGIS and MATLAB environments. The networks structures have been chosen during a computer simulation based on the minimization of the RMSE. MLRPK showed the best predictive accuracy comparing to the geostatistical approach (kriging) and even to GRNNRK.

New hesitation-based distance and similarity measures on intuitionistic fuzzy sets and their applications

NASA Astrophysics Data System (ADS)

Kang, Yun; Wu, Shunxiang; Cao, Da; Weng, Wei

2018-03-01

In this paper, we present new definitions on distance and similarity measures between intuitionistic fuzzy sets (IFSs) by combining with hesitation degree. First, we discuss the limitations in traditional distance and similarity measures, which are caused by the neglect of hesitation degree's influence. Even though a vector-valued similarity measure was proposed, which has two components indicating similarity and hesitation aspects, it still cannot perform well in practical applications because hesitation works only when the values of similarity measures are equal. In order to overcome the limitations, we propose new definitions on hesitation, distance and similarity measures, and research some theorems which satisfy the requirements of the proposed definitions. Meanwhile, we investigate the relationships among hesitation, distance, similarity and entropy of IFSs to verify the consistency of our work and previous research. Finally, we analyse and discuss the advantages and disadvantages of the proposed similarity measure in detail, and then we apply the proposed measures (dH and SH) to deal with pattern recognition problems, and demonstrate that they outperform state-of-the-art distance and similarity measures.

Separating Facts from Fiction: Linguistic Models to Classify Suspicious and Trusted News Posts on Twitter

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

Volkova, Svitlana; Shaffer, Kyle J.; Jang, Jin Yea

Pew research polls report 62 percent of U.S. adults get news on social media (Gottfried and Shearer, 2016). In a December poll, 64 percent of U.S. adults said that “made-up news” has caused a “great deal of confusion” about the facts of current events (Barthel et al., 2016). Fabricated stories spread in social media, ranging from deliberate propaganda to hoaxes and satire, contributes to this confusion in addition to having serious effects on global stability. In this work we build predictive models to classify 130 thousand news tweets as suspicious or verified, and predict four subtypes of suspicious news –more » satire, hoaxes, clickbait and propaganda. We demonstrate that neural network models trained on tweet content and social network interactions outperform lexical models. Unlike previous work on deception detection, we find that adding syntax and grammar features to our models decreases performance. Incorporating linguistic features, including bias and subjectivity, improves classification results, however social interaction features are most informative for finer-grained separation between our four types of suspicious news posts.« less

Dealing with the Effects of Sensor Displacement in Wearable Activity Recognition

PubMed Central

Banos, Oresti; Toth, Mate Attila; Damas, Miguel; Pomares, Hector; Rojas, Ignacio

2014-01-01

Most wearable activity recognition systems assume a predefined sensor deployment that remains unchanged during runtime. However, this assumption does not reflect real-life conditions. During the normal use of such systems, users may place the sensors in a position different from the predefined sensor placement. Also, sensors may move from their original location to a different one, due to a loose attachment. Activity recognition systems trained on activity patterns characteristic of a given sensor deployment may likely fail due to sensor displacements. In this work, we innovatively explore the effects of sensor displacement induced by both the intentional misplacement of sensors and self-placement by the user. The effects of sensor displacement are analyzed for standard activity recognition techniques, as well as for an alternate robust sensor fusion method proposed in a previous work. While classical recognition models show little tolerance to sensor displacement, the proposed method is proven to have notable capabilities to assimilate the changes introduced in the sensor position due to self-placement and provides considerable improvements for large misplacements.

Twenty-three Taiwanese infants with unilateral cleft lip and palate (UCLP) were CT-scanned before lip repair at the age of 3 months, and again after lip repair at the age of 12 months. In order to evaluate the surgical result, detailed point correspondence between pre- and post-surgical images was needed. We have previously demonstrated that non-rigid registration using B-splines is able to provide automated determination of point correspondences in populations of infants without cleft lip. However, this type of registration fails when applied to the task of determining the complex deformation from before to after lip closure in infants with UCLP. The purpose of the present work was to show that use of prior information about typical deformations due to lip closure, through the construction of a knowledge-based atlas of deformations, could overcome the problem. Initially, mean volumes (atlases) for the pre- and post-surgical populations, respectively, were automatically constructed by non-rigid registration. An expert placed corresponding landmarks in the cleft area in the two atlases; this provided prior information used to build a knowledge-based deformation atlas. We model the change from pre- to post-surgery using thin-plate spline warping. The registration results are convincing and represent a first move towards an automatic registration method for dealing with difficult deformations due to this type of surgery.

People have known the bacteria and have used various ways to deal with them, from a long time ago. Perhaps, natural antibiotics with have been the first step in fighting against pathogens. However, several factors, such as dealing with unfamiliar bacteria or emergence of drug-resistant species, have motivated us to discover new antibiotics or  even change previous types. In this regard, a variety of natural and synthetic antibiotics with different origins, mechanism of action, structures and functional spectrum, have been developed and used. Some impact on the synthesis of nucleic acids and some affect protein synthesis so destroy bacteria. There is a ring in the structure of most of the antibiotics which gives them special properties. However, despite their numerous advantages, antibiotics also have drawbacks ehich limit their use in all situations. Therefore, other approaches such as photodynamic therapy (PDT) and antibacterial peptides were considered as alternatives. Photodynamic therapy (PDT) is a treatment that uses photosensitizing agents, along with light, to kill bacteria. The photosensitizing agents only work after they have been activated by certain kinds of light. Antibacterial peptides are a unique and diverse group of molecules which have  between 12 and 50 amino acids in general.  In this paper, will reviewt hree mentioned topics, namely antibiotics, photodynamic therapy and antibacterial peptides and will discuss the advantages and disadvantages of each approach briefly.

Generation Expansion Planning With Large Amounts of Wind Power via Decision-Dependent Stochastic Programming

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

Zhan, Yiduo; Zheng, Qipeng P.; Wang, Jianhui

Power generation expansion planning needs to deal with future uncertainties carefully, given that the invested generation assets will be in operation for a long time. Many stochastic programming models have been proposed to tackle this challenge. However, most previous works assume predetermined future uncertainties (i.e., fixed random outcomes with given probabilities). In several recent studies of generation assets' planning (e.g., thermal versus renewable), new findings show that the investment decisions could affect the future uncertainties as well. To this end, this paper proposes a multistage decision-dependent stochastic optimization model for long-term large-scale generation expansion planning, where large amounts of windmore » power are involved. In the decision-dependent model, the future uncertainties are not only affecting but also affected by the current decisions. In particular, the probability distribution function is determined by not only input parameters but also decision variables. To deal with the nonlinear constraints in our model, a quasi-exact solution approach is then introduced to reformulate the multistage stochastic investment model to a mixed-integer linear programming model. The wind penetration, investment decisions, and the optimality of the decision-dependent model are evaluated in a series of multistage case studies. The results show that the proposed decision-dependent model provides effective optimization solutions for long-term generation expansion planning.« less

Verbal aggression has been defined as communication with an intention to harm an individual through words, tone or manner, regardless of whether harm occurs. It includes verbal threat to harm, ridicule, openly hostile remarks, unjust persistent criticism, shouting or yelling insults, as well as more covert actions such as spreading hurtful rumours (Cox, 1987; Farrell et al, 2006). Receiving verbal aggression from a patient has been closely associated with psychological distress which may negatively affect work performance. A verbal aggression work book was developed to help nursing staff to deal with verbal aggression from patients in clinical practice. This was piloted over a six-week period with 18 nurses working on one acute psychiatric inpatient ward. Findings revealed that the intervention had some promising effects. However, much more attention needs to be paid to changing attitudes towards verbal aggression.

Nursing and the New Deal: we met the challenge.

PubMed

Pollitt, P; Reese, C N

1997-12-01

The years of the great depression were marked with unemployment and economic ruin for many people. Americans were left feeling helpless and hopeless. After the 1932 presidential election of Franklin Roosevelt, his administration embarked on a course of government known as the New Deal. Many new and innovative programs were established to create jobs and a sense of hope for the public. This article will examine four programs that were of particular interest to nursing: the Federal Emergency Relief Act, the Civil Works Act, the Works Progress Act, and the Social Security Act. Nurses of the time embraced these programs. They participated in their development and implementation and made a difference in the lives of many desperate Americans.

The Public Health Responsibility Deal: brokering a deal for public health, but on whose terms?

PubMed

Panjwani, Clare; Caraher, Martin

2014-02-01

Coalitions of multinational food and drink businesses have pledged to reformulate their products and to market them responsibly. Largely business-led and self-regulated, the integrity of these voluntary initiatives has been questioned. The Public Health Responsibility Deal in England is an example of a voluntary initiative that is government-led. Does this approach provide evidence that with public leadership there is potential for voluntary actions to deliver meaningful results for public health? The subject of the research is the calorie reduction initiative of the Responsibility Deal. Source material was obtained primarily through a series of UK Freedom of Information requests and comprises previously unpublished Department of Health documentation relating to relevant meetings held during 2011 and 2012. The Responsibility Deal approach to calorie reduction deliberately involves the food industry in the specification of the measures it is to implement (reformulation and portion control). Finding the common ground between private and public interests has resulted in the deflection of public health objectives and the preclusion of adequate monitoring and evaluation. The Responsibility Deal approach is fundamentally flawed in its expectation that industry will take voluntary actions that prioritise public health interests above its own. Being government-led counts for little in the absence of sanctions to drive compliance. Instead the initiative affords private interests the opportunity to influence in their favour the public health policies and strategies that affect their products.

Disaster Research: A Nursing Opportunity

PubMed Central

Savage, Jane; Barcelona-deMendoza, Veronica; Harville, Emily W.

2013-01-01

Nurses working or living near a community disaster have the opportunity to study health-related consequences to disaster or disaster recovery. In such a situation, the researchers need to deal with the conceptual and methodological issues unique to post-disaster research and know what resources are available to guide them, even if they have no specialized training or previous experience in disaster research. The purpose of this article is to review issues and challenges associated with conducting post-disaster research and encourage nurses to seek resources and seize opportunities to conduct research should the situation arise. Current disaster studies and the authors’ personal experiences conducting maternal-child research in post-Katrina New Orleans (2005–2013) provide real-life examples of how health professionals and nurses faced the challenges of doing post-disaster research. After catastrophic events, nurses need to step forward to conduct disaster research that informs and improves future disaster planning and health care responses. PMID:23899191

Online Coregularization for Multiview Semisupervised Learning

PubMed Central

Li, Guohui; Huang, Kuihua

2013-01-01

We propose a novel online coregularization framework for multiview semisupervised learning based on the notion of duality in constrained optimization. Using the weak duality theorem, we reduce the online coregularization to the task of increasing the dual function. We demonstrate that the existing online coregularization algorithms in previous work can be viewed as an approximation of our dual ascending process using gradient ascent. New algorithms are derived based on the idea of ascending the dual function more aggressively. For practical purpose, we also propose two sparse approximation approaches for kernel representation to reduce the computational complexity. Experiments show that our derived online coregularization algorithms achieve risk and accuracy comparable to offline algorithms while consuming less time and memory. Specially, our online coregularization algorithms are able to deal with concept drift and maintain a much smaller error rate. This paper paves a way to the design and analysis of online coregularization algorithms. PMID:24194680

2014-12-01

This manuscript deals with the generalisation of all previous works on series solutions and linear stability of equilibrium points of the Sitnikov problem. Following Giacaglia (1967), in Sect. 2 we have derived the equation of motion of the infinitesimal mass moving along the z-axis about which the plane of motion is rotating with unit angular velocity. In Sects. 3, 4 and 5 the series solutions of the Sitnikov problem have been developed by the method of MacMillan, Lindstedt-Poincaré and iteration of Green's function respectively. In Sect. 6 the three series solutions have been compared graphically by putting N=2, 3, 4. In Sect. 7 the coordinates of equilibrium points have been calculated. In Sect. 8 the linear stability of equilibrium points has been examined by the method of Murray and Dermott (Solar System Dynamics, Cambridge University Press, Cambridge, 1999) and it was found that the equilibrium points are stable in Sitnikov problem.

The Boundary Layer Flows of a Rivlin-Ericksen Fluid

NASA Astrophysics Data System (ADS)

Sadeghy, K.; Khabazi, N.; Taghavi, S. M.

The present work deals with the two-dimensional incompressible, laminar, steady-state boundary layer equations. First, we determine a family of velocity distributions outside the boundary layer such that these problems may have similarity solutions. We study the Falkner-Skan flow of a viscoelastic fluid governed by second order model, as the Reynolds number Re→ ∞. We obtain an ordinary forth order differential equation to obtain the stream function, velocity profile and the stress. The stream function is then governed by a generalized Falkner-Skan equation. In comparison with Newtonian Falkner-Skan equation that has two coefficients this new one has four coefficients that two of them represent elastic properties of the fluid. The effects of the elastic parameter on the velocity filed have been discussed. As it is shown in the figure there is a good agreement between numerical results and previous special cases confirm the validity of the presented algorithm.

Towards understanding addiction factors of mobile devices: An eye tracking study on effect of screen size.

PubMed

Wibirama, Sunu; Nugroho, Hanung A

2017-07-01

Mobile devices addiction has been an important research topic in cognitive science, mental health, and human-machine interaction. Previous works observed mobile device addiction by logging mobile devices activity. Although immersion has been linked as a significant predictor of video game addiction, investigation on addiction factors of mobile device with behavioral measurement has never been done before. In this research, we demonstrated the usage of eye tracking to observe effect of screen size on experience of immersion. We compared subjective judgment with eye movements analysis. Non-parametric analysis on immersion score shows that screen size affects experience of immersion (p<;0.05). Furthermore, our experimental results suggest that fixational eye movements may be used as an indicator for future investigation of mobile devices addiction. Our experimental results are also useful to develop a guideline as well as intervention strategy to deal with smartphone addiction.

A dynamic scheduling algorithm for singe-arm two-cluster tools with flexible processing times

NASA Astrophysics Data System (ADS)

Li, Xin; Fung, Richard Y. K.

2018-02-01

This article presents a dynamic algorithm for job scheduling in two-cluster tools producing multi-type wafers with flexible processing times. Flexible processing times mean that the actual times for processing wafers should be within given time intervals. The objective of the work is to minimize the completion time of the newly inserted wafer. To deal with this issue, a two-cluster tool is decomposed into three reduced single-cluster tools (RCTs) in a series based on a decomposition approach proposed in this article. For each single-cluster tool, a dynamic scheduling algorithm based on temporal constraints is developed to schedule the newly inserted wafer. Three experiments have been carried out to test the dynamic scheduling algorithm proposed, comparing with the results the 'earliest starting time' heuristic (EST) adopted in previous literature. The results show that the dynamic algorithm proposed in this article is effective and practical.

A phenomenological retention tank model using settling velocity distributions.

Maruejouls, T; Vanrolleghem, P A; Pelletier, G; Lessard, P

2012-12-15

Many authors have observed the influence of the settling velocity distribution on the sedimentation process in retention tanks. However, the pollutants' behaviour in such tanks is not well characterized, especially with respect to their settling velocity distribution. This paper presents a phenomenological modelling study dealing with the way by which the settling velocity distribution of particles in combined sewage changes between entering and leaving an off-line retention tank. The work starts from a previously published model (Lessard and Beck, 1991) which is first implemented in a wastewater management modelling software, to be then tested with full-scale field data for the first time. Next, its performance is improved by integrating the particle settling velocity distribution and adding a description of the resuspension due to pumping for emptying the tank. Finally, the potential of the improved model is demonstrated by comparing the results for one more rain event. Copyright © 2011 Elsevier Ltd. All rights reserved.

Ancona Alayón; Aranda Martínez, J G

1978-01-01

Cement dermatitis manifests clinically as a chronic dermatitis of irritative character, due to its alkaline nature and as allergic contact dermatitis produced by sensitization to chromium and cobalt occurring as trace elements. the present report deals with a mason without previous dermatitis, presenting bullae, ulcers and necrosis in lower limbs, short time after incidental contact at work, with premixed concrete. The clinical manifestations, such as short evolution, clear limitation to sites in close contact with concrete, negativity to standard patch testing and good prognosis with early treatment, are mentioned. The acute irritant nature of the disease is clear, in opposition to the classical manifestations of cement dermatitis. The need of studies of the chemical properties of this material including pH, alkalinity and the possible roll of additives employed, is part of the strategy for prevention of occupational dermatitis in the building trade, which should include also, information of hazards and proper training in their trade.

Well-Being and Safety among Inpatient Psychiatric Staff: The Impact of Conflict, Assault, and Stress Reactivity

PubMed Central

Kelly, Erin L.; Fenwick, Karissa; Brekke, John S.; Novaco, Raymond W.

2015-01-01

Psychiatric staff are faced with multiple forms of hostility, aggression, and assault at work, collectively referred to as workplace violence, which typically is activated by patients but can also come from coworkers and supervisors. Whether workplace violence adversely affects staff well-being may be related not only to its presence, but also to an individual’s stress reactivity. At a large public psychiatric hospital, an online survey was completed by 323 clinical care staff, of whom 69.5% had experienced physical assault in the previous 12 months. Staff well-being (depression, anger, and physical health) and staff safety concerns were adversely affected by conflicts with other staff members and by individual reactivity to social conflict and to assault. To improve staff well-being, in addition to safety protocols, interventions should target staff relationships, personal health maintenance practices, and individual coping skills for dealing with adverse workplace experiences.

Influence of gas law on ultrasonic behaviour of porous media under pressure.

PubMed

Griffiths, S; Ayrault, C

2010-06-01

This paper deals with the influence of gas law on ultrasonic behaviour of porous media when the saturating fluid is high pressured. Previous works have demonstrated that ultrasonic transmission through a porous sample with variations of the static pressure (up to 18 bars) of the saturating fluid allows the characterization of high damping materials. In these studies, the perfect gas law was used to link static pressure and density, which is disputable for high pressures. This paper compares the effects of real and perfect gas laws on modeled transmission coefficient for porous foams at these pressures. Direct simulations and a mechanical parameters estimation from minimization show that results are very similar in both cases. The real gas law is thus not necessary to describe the acoustic behaviour of porous media at low ultrasonic frequencies (100 kHz) up to 20 bars. 2010 Elsevier B.V. All rights reserved.

Resveratrol and cancer: Challenges for clinical translation

Singh, Chandra K.; Ndiaye, Mary A.; Ahmad, Nihal

2014-01-01

Significant work has been done towards identifying the health-beneficial effects of the grape antioxidant resveratrol in a variety of bioassay- and disease- models, with much research being focused on its possible application to cancer management. Despite the large number of preclinical studies dealing with different aspects of the biological effects of resveratrol, it’s translation to clinics is far from reality due to a variety of challenges. In this review, we discuss the issues and questions associated with resveratrol becoming an effective in vivo anticancer drug, from basic metabolic issues to the problems faced by incomplete understanding of the mechanism(s) of action in the body. We also explore efforts taken by researchers, both public and private, to contend with some of these issues. By examining the published data and previous clinical trials, we have attempted to identify the problems and issues that hinder the clinical translation of resveratrol for cancer management.

A novel game theoretic approach for modeling competitive information diffusion in social networks with heterogeneous nodes

Agha Mohammad Ali Kermani, Mehrdad; Fatemi Ardestani, Seyed Farshad; Aliahmadi, Alireza; Barzinpour, Farnaz

2017-01-01

Influence maximization deals with identification of the most influential nodes in a social network given an influence model. In this paper, a game theoretic framework is developed that models a competitive influence maximization problem. A novel competitive influence model is additionally proposed that incorporates user heterogeneity, message content, and network structure. The proposed game-theoretic model is solved using Nash Equilibrium in a real-world dataset. It is shown that none of the well-known strategies are stable and at least one player has the incentive to deviate from the proposed strategy. Moreover, violation of Nash equilibrium strategy by each player leads to their reduced payoff. Contrary to previous works, our results demonstrate that graph topology, as well as the nodes' sociability and initial tendency measures have an effect on the determination of the influential node in the network.

For Which Side the Bell Tolls: The Laterality of Approach-Avoidance Associative Networks.

PubMed

Fetterman, Adam K; Ode, Scott; Robinson, Michael D

2013-03-01

The two hemispheres of the brain appear to play different roles in emotion and/or motivation. A great deal of previous research has examined the valence hypothesis (left hemisphere = positive; right = negative), but an increasing body of work has supported the motivational hypothesis (left hemisphere = approach; right = avoidance) as an alternative. The present investigation ( N = 117) sought to provide novel support for the latter perspective. Left versus right hemispheres were briefly activated by neutral lateralized auditory primes. Subsequently, participants categorized approach versus avoidance words as quickly and accurately as possible. Performance in the task revealed that approach-related thoughts were more accessible following left-hemispheric activation, whereas avoidance-related thoughts were more accessible following right-hemispheric activation. The present results are the first to examine such lateralized differences in accessible motivational thoughts, which may underlie more "downstream" manifestations of approach and avoidance motivation such as judgments, decision making, and behavior.

Work environment as predictor of long-term sickness absence: linkage of self-reported DWECS data with the DREAM register.

PubMed

Burr, Hermann; Pedersen, Jacob; Hansen, Jørgen Vinsløv

2011-07-01

The present overview discusses ten papers dealing with four research topics using self-reported work environment in the Danish Work Environment Cohort Study (DWECS) linked with register data on long-term sickness absence (LTSA) in the Danish Register for Evaluation of Marginalisation (DREAM). Research relied on self-reported data among 3000-5000 employees linked with registered LTSA data. Analyses were performed with Cox regression models. Risk groups: Kindergarten teachers and daycare workers were at high risk for LTSA. Mainly physical exposures but also psychosocial factors were risk factors for LTSA. Attributable fractions: A quarter of LTSA spells could be attributed to the physical work environment. Most of the association between social class and LTSA was explained by physical work environment and smoking. Mechanisms: Depressive symptoms, severe pain in hands, and low back and pain intensity were risk factors for LTSA. Only in work sites with traditional leadership did health problems predict LTSA. The linking of DWECS with DREAM has made it possible to estimate the importance of work environment factors for LTSA. Future research should deal with possible risk factors such as health problems and organisational factors.

Nonlinear THz absorption and cyclotron resonance in InSb

NASA Astrophysics Data System (ADS)

Heffernan, Kate; Yu, Shukai; Talbayev, Diyar

The emergence of coherent high-field terahertz (THz) sources in the past decade has allowed the exploration of nonlinear light-matter interaction at THz frequencies. Nonlinear THz response of free electrons in semiconductors has received a great deal of attention. Such nonlinear phenomena as saturable absorption and self-phase modulation have been reported. InSb is a narrow-gap (bandgap 0.17 eV) semiconductor with a very low electron effective mass and high electron mobility. Previous high-field THz work on InSb reported the observation of ultrafast electron cascades via impact ionization. We study the transmission of an intense THz electric field pulse by an InSb wafer at different incident THz amplitudes and 10 K temperature. Contrary to previous reports, we observe an increased transmission at higher THz field. Our observation appears similar to the saturable THz absorption reported in other semiconductors. Along with the increased absorption, we observe a strong modulation of the THz phase at high incident fields, most likely due to the self-phase modulation of the THz pulse. We also study the dependence of the cyclotron resonance on the incident THz field amplitude. The cyclotron resonance exhibits a lower strength and frequency at the higher incident THz field.

Learning from Trending, Precursor Analysis, and System Failures

Youngblood, R. W.; Duffey, R. B.

2015-11-01

Models of reliability growth relate current system unreliability to currently accumulated experience. But “experience” comes in different forms. Looking back after a major accident, one is sometimes able to identify previous events or measurable performance trends that were, in some sense, signaling the potential for that major accident: potential that could have been recognized and acted upon, but was not recognized until the accident occurred. This could be a previously unrecognized cause of accidents, or underestimation of the likelihood that a recognized potential cause would actually operate. Despite improvements in the state of practice of modeling of risk and reliability,more » operational experience still has a great deal to teach us, and work has been going on in several industries to try to do a better job of learning from experience before major accidents occur. It is not enough to say that we should review operating experience; there is too much “experience” for such general advice to be considered practical. The paper discusses the following: 1. The challenge of deciding what to focus on in analysis of operating experience. 2. Comparing what different models of learning and reliability growth imply about trending and precursor analysis.« less

Additional programs for training specialists were developed, the State License for conducting the course of special post-diploma training was obtained. Research works on improving the methods of the indication and rapid diagnostics of the causative agents of dangerous infections, reflected in training programs for specialists and practically used in the process of the realization of antiepidemic measures in the zones of emergency situations, were carried out. In training the students the experience of the work of the institute on ensuring the epidemiological safety of the population under the conditions of different emergency situations was taken into consideration.

Work and family role juggling and mood states of Hong Kong public health nurses with children.

PubMed

Shiu, A T

1998-07-01

This study aims to investigate the daily mood states of public health nurses (PHNs) in managerial roles with children in Hong Kong, as a result of multiple role juggling (i.e. simultaneously attending to demands of different roles) using the experience sampling method. Convenience sampling was used to recruit 20 subjects. A watch was worn that beeped at six random times each day for 7 days as a signal to complete an experience sampling diary. PHNs on average responded to 34 signals (80%) to complete the experience sampling diaries. Two major findings provide the focus of this paper. First, results show that PHNs had minimal inter-role juggling between work and family as compared with previous studies in the United States. Cultural factors, sequentially dealing with family and work issues, having a domestic maid or a relative to see to household chores as well as strong spouse support are suggested as the reasons. These results have implications for nursing management and nursing practice. Second, the results also reveal PHNs as having an overall flat affect. It is suggested that PHNs may be using a 'calm and detached' coping style for occupational stress. This coping style has implications on the PHNs' emotional health as well as nurse-client relationships.

CANS causes significant work problems, including absenteeism (sickness absence), presenteeism (decreased work productivity) and, ultimately, job loss. There is a need for intervention programs for people suffering from CANS. Management of symptoms and workload, and improving the workstyle, could be important factors in the strategy to deal with CANS. The objective of this study is to evaluate the experienced problems of employees with CANS, as a first step in an intervention mapping process aimed at adaptation of an existing self-management program to the characteristics of employees suffering from CANS. Methods A qualitative study comprising three focus group meetings with 15 employees suffering from CANS. Based on a question guide, participants were asked about experiences in relation to continuing work despite their complaints. Data were analysed using content analysis with an open-coding system. During selective coding, general themes and patterns were identified and relationships between the codes were examined. Results Participants suffering from CANS often have to deal with pain, disability, fatigue, misunderstanding and stress at work. Some needs of the participants were identified, i.e. disease-specific information, exercises, muscle relaxation, working with pain, influence of the work and/or social environment, and personal factors (including workstyle). Conclusions Employees suffering from CANS search for ways to deal with their complaints in daily life and at work. This study reveals several recurring problems and the results endorse the multi-factorial origin of CANS. Participants generally experience problems similar to those of employees with other types of complaints or chronic diseases, e.g. related to their illness, insufficient communication, working together with healthcare professionals, colleagues and management, and workplace adaptations. These topics will be addressed in the adaptation of an existing self-management program to the characteristics of employees suffering from CANS. PMID:24779360

Unemployment, health and health services in German-speaking countries.

PubMed

Schwefel, D

1986-01-01

The links between unemployment and health are manifold: Employment may lead to illness: health problems (that may lead to unemployment) often result from unfavourable working conditions of the (previous) employment. Another factor is job insecurity: fear of job loss increases the incidence of disease, and this applies not only to people who are emotionally unstable. Illness may lead to unemployment: in many cases, unemployment is caused by previous health impairments, which, to a considerable extent, also explain the duration of unemployment. Unemployment may lead to illness: there is evidence that unemployment not only reinforces existing physical disease but also acts as a risk factor for new ones. This seems particularly true for problem groups such as the unemployed elderly as well as for infants and children of unemployed people. The relations between unemployment and mental health are strong, mainly in terms of depression and alcoholism. Unemployment may lead to health: short-time work and short-term unemployment may improve health by reducing previous stress, caused by employment or by an overload with social roles. Even in the case of long-term unemployment there are some positive health effects as long as a minimum of social security and alternative social roles are available and useful activities--minor agricultural jobs, illicit work--can be carried out. The links between unemployment, work and society can considerably be loosened by a number of social factors and personal characteristics of the people affected. Existing health services are not in a position to deal with disease stemming from employment or unemployment except through symptomatical and curative therapies. In addition to general medical care, which is guaranteed by the German health insurance system for the unemployed, too, therapeutical measures are especially important in cases of depression and alcoholism. As a rule, the medical profession has no knowledge of the links between health, work and unemployment; such knowledge, however, would facilitate prevention. Individual prevention and rehabilitation measures are of great importance to problem groups suffering from cumulative or indirect unemployment, i.e. to unemployed elderly as well as to children of unemployed parents. Since the unemployed tend to isolate themselves, extramural services are useful. Specific services for the unemployed only are certainly not as helpful as multi-functional social services, such as those being already rendered by some self-help organizations, churches and trade-unions.(ABSTRACT TRUNCATED AT 400 WORDS)

Evolving minds: Helping students with cognitive dissonance

NASA Astrophysics Data System (ADS)

Bramschreiber, Terry L.

Even 150 years after Charles Darwin published On the Origin of Species, public school teachers still find themselves dealing with student resistance to learning about biological evolution. Some teachers deal with this pressure by undermining, deemphasizing, or even omitting the topic in their science curriculum. Others face the challenge and deliver solid scientific instruction of evolutionary theory despite the conflicts that may arise. The latter were the topic of this study. I interviewed five teachers that had experience dealing with resistance to learning evolution in their school community. Through these in-depth interviews, I examined strategies these teachers use when facing resistance and how they help students deal with the cognitive dissonance that may be experienced when learning about evolution. I selected the qualitative method of educational criticism and connoisseurship to organize and categorize my data. From the interviews, the following findings emerged. Experienced teachers increased their confidence in teaching evolution by pursuing outside professional development. They not only learned more about evolutionary theory, but about creationist arguments against evolution. These teachers front-load their curriculum to integrate the nature of science into their lessons to address misunderstandings about how science works. They also highlight the importance of learning evolutionary theory but ensure students they do not have an agenda to indoctrinate students. Finally these experienced teachers work hard to create an intellectually safe learning environment to build trusting and respectful relationships with their students.

As in previous years, we felt it would be of value to our readership to summarize the new information provided by the authors who have published in Clinical and Experimental Allergy in 2011 and set this in the context of recent advances in our understanding of the pathogenesis and management of allergic disease in all its many manifestations. In 2011, about 210 articles were published in Clinical and Experimental Allergy including editorials, reviews, opinion articles, guidelines, letters, book reviews and of course at the heart of the journal, papers containing original data. As before, this review is divided into sections based on the way the journal is structured, although this year we have grouped together all the papers dealing with mechanisms of allergic disease, whether they involve patients (clinical mechanisms), pure in vitro studies (basic mechanisms) or animal models (experimental models), as we felt this was a more coherent way to deal with the subject. In the field of asthma and rhinitis, the relationship between airway inflammation and airway dysfunction was of perennial interest to investigators, as were phenotypes and biomarkers. Aspirin hypersensitivity appeared in studies in several papers and there was new interest in asthma in the elderly. The mechanisms involved in allergic disease describe advances in our understanding of T cell responses, the relationship between inflammation and disease, mast cell and basophil activation, steroid resistance and novel therapies. In the section dealing with epidemiology, studies seeking to identify risk factors for allergic disease including vitamin D are prominent, as once again are studies investigating gene-environment interactions. The clinical allergy section focuses on drug allergy, food allergy and immunotherapy. The area of oral immunotherapy for food allergy is well covered and we were grateful to Stephen Durham for guest editing an outstanding special issue on immunotherapy in the centenary year of Leonard Noon's pioneering work. Lastly, in the field of allergens, the interest in component-resolved diagnosis continues to grow and there are also articles describing important novel cultivars and the effect of food processing on the allergenic properties of foods. Another terrific year, full of important and high-quality work,which the journal has been proud to bring to the allergy community. © 2012 Blackwell Publishing Ltd.

Work can be an important etiologic factor in the genesis of some mental disorders including cognitive disability. Occupational neuropsychology constitutes an intriguing new but neglected area of research and clinical practice which deals with the neurocognitive consequences of the work environment and work habits. Neuropsychological knowledge is fundamental to understand cognitive requirements of work competence. Work can impact sleep patterns and mental energy, which in turn can cause neuropsychological symptoms. This report presents relevant evidence to illustrate the relationship between work and cognitive dysfunction. PMID:29213798

Inhibition, flexibility, working memory and planning in autism spectrum disorders with and without comorbid ADHD-symptoms

2008-01-01

Background Recent studies have not paid a great deal of attention to comorbid attention-deficit/hyperactivity disorder (ADHD) symptoms in autistic children even though it is well known that almost half of children with autism spectrum disorder (ASD) suffer from hyperactivity, inattention and impulsivity. The goal of this study was to evaluate and compare executive functioning (EF) profiles in children with ADHD and in children with ASD with and without comorbid ADHD. Methods Children aged 6 to 18 years old with ADHD (n = 20) or ASD (High-Functioning autism or Asperger syndrome) with (n = 20) and without (n = 20) comorbid ADHD and a typically developing group (n = 20) were compared on a battery of EF tasks comprising inhibition, flexibility, working memory and planning tasks. A MANOVA, effect sizes as well as correlations between ADHD-symptomatology and EF performance were calculated. Age- and IQ-corrected z scores were used. Results There was a significant effect for the factor group (F = 1.55; dF = 42; p = .02). Post-hoc analysis revealed significant differences between the ADHD and the TD group on the inhibition task for false alarms (p = .01) and between the ADHD group, the ASD+ group (p = .03), the ASD- group (p = .02) and the TD group (p = .01) for omissions. Effect sizes showed clear deficits of ADHD children in inhibition and working memory tasks. Participants with ASD were impaired in planning and flexibility abilities. The ASD+ group showed compared to the ASD- group more problems in inhibitory performance but not in the working memory task. Conclusion Our findings replicate previous results reporting impairment of ADHD children in inhibition and working memory tasks and of ASD children in planning and flexibility abilities. The ASD + group showed similarities to the ADHD group with regard to inhibitory but not to working memory deficits. Nevertheless the heterogeneity of these and previous results shows that EF assessment is not useful for differential diagnosis between ADHD and ASD. It might be useful for evaluating strengths and weaknesses in individual children. PMID:18237439

[Learning by doing? The restructuring of nursing education after 1945].

PubMed

Kreutzer, Susanne

2007-01-01

This study deals with the reform of nursing education on a day-to-day level and exemplifies the dramatic change in the image of nursing in the 1960s, when the erstwhile religious calling was transformed into a modern-day female profession. The analysis is based on interviews with two different groups of nurses who were educated between the 1930s and 1960s. The first group is composed of the deaconesses of a Protestant mother-house in Hannover (Henriettenstiftung). The second group is formed by nurses who were noted for their important role in the professionalisation of nursing in West Germany. The methodology of this study draws on the experiences of the practice of oral history which reflects the actual context of the narratives, the problem of commemoration and the relationship between individual and collective memory. Nursing education, as late as the 1950s, was based on practical experience. The nursing students were responsible for a certain number of patients from the very first day of their training. Comparison of the different narratives shows that such an experience-based training principle was bound to a specific, family-like concept of nursing which was supported by the sisterhoods. This traditional system of nursing education changed essentially in the 1960s when knowledge based on experience lost a great deal of its meaning, while a theory-based training took preference. Furthermore, the regulation and fragmentation of nursing education increased significantly. The outcome was that continuity in caring for patients decreased dramatically in the 1960s and it became much more difficult to learn how to observe the sick and to demand confidence in dealing with patients. The reform of nursing education also had far-reaching consequences for the construction of everyday life in the wards as the students had previously undertaken a major part of the work.

How to Pinpoint Energy-Inefficient Buildings? AN Approach Based on the 3d City Model of Vienna

NASA Astrophysics Data System (ADS)

Skarbal, B.; Peters-Anders, J.; Faizan Malik, A.; Agugiaro, G.

2017-09-01

This paper describes a methodology to assess the energy performance of residential buildings starting from the semantic 3D city model of Vienna. Space heating, domestic hot water and electricity demand are taken into account. The paper deals with aspects related to urban data modelling, with particular attention to the energy-related topics, and with issues related to interactive data exploration/visualisation and management from a plugin-free web-browser, e.g. based on Cesium, a WebGL virtual globe and map engine. While providing references to existing previous works, only some general and introductory information is given about the data collection, harmonisation and integration process necessary to create the CityGML-based 3D city model, which serves as the central information hub for the different applications developed and described more in detail in this paper. The work aims, among the rest, at developing urban decision making and operational optimisation software tools to minimise non-renewable energy use in cities. The results obtained so far, as well as some comments about their quality and limitations, are presented, together with the discussion regarding the next steps and some planned improvements.

Space Psychology and Psychiatry

NASA Astrophysics Data System (ADS)

Kanas, N.; Manzey, D.

2003-09-01

This book deals with psychological, psychiatric, and psychosocial issues that affect people who live and work in space. Unlike other books that focus on anecdotal reports and ground-based simulation studies, this book emphasizes the findings from psychological research conducted during actual space missions. Both authors have been active in such research. What is presented in this readable text has previously been found only in scientific journal articles. Topics that are discussed include: behavioral adaptation to space; human performance and cognitive effects; crewmember interactions; psychiatric responses; psychological counter-measures related to habitability factors, work-design, selection, training, and in-flight monitoring and support; and the impact of expeditionary missions to Mars and beyond. People finding this book of interest will include: psychology and social science students and professors in universities; medical students and residents in psychiatry and aerospace medicine; human factors workers in space and aviation professions; individuals involved with isolated environments on Earth (e.g., the Antarctic, submarines); aerospace workers in businesses and space agencies such as NASA and ESA; and anyone who is interested in learning the facts about the human side of long-duration space missions.

A reference estimator based on composite sensor pattern noise for source device identification

NASA Astrophysics Data System (ADS)

Li, Ruizhe; Li, Chang-Tsun; Guan, Yu

2014-02-01

It has been proved that Sensor Pattern Noise (SPN) can serve as an imaging device fingerprint for source camera identification. Reference SPN estimation is a very important procedure within the framework of this application. Most previous works built reference SPN by averaging the SPNs extracted from 50 images of blue sky. However, this method can be problematic. Firstly, in practice we may face the problem of source camera identification in the absence of the imaging cameras and reference SPNs, which means only natural images with scene details are available for reference SPN estimation rather than blue sky images. It is challenging because the reference SPN can be severely contaminated by image content. Secondly, the number of available reference images sometimes is too few for existing methods to estimate a reliable reference SPN. In fact, existing methods lack consideration of the number of available reference images as they were designed for the datasets with abundant images to estimate the reference SPN. In order to deal with the aforementioned problem, in this work, a novel reference estimator is proposed. Experimental results show that our proposed method achieves better performance than the methods based on the averaged reference SPN, especially when few reference images used.

Associative memory for online learning in noisy environments using self-organizing incremental neural network.

PubMed

Sudo, Akihito; Sato, Akihiro; Hasegawa, Osamu

2009-06-01

Associative memory operating in a real environment must perform well in online incremental learning and be robust to noisy data because noisy associative patterns are presented sequentially in a real environment. We propose a novel associative memory that satisfies these requirements. Using the proposed method, new associative pairs that are presented sequentially can be learned accurately without forgetting previously learned patterns. The memory size of the proposed method increases adaptively with learning patterns. Therefore, it suffers neither redundancy nor insufficiency of memory size, even in an environment in which the maximum number of associative pairs to be presented is unknown before learning. Noisy inputs in real environments are classifiable into two types: noise-added original patterns and faultily presented random patterns. The proposed method deals with two types of noise. To our knowledge, no conventional associative memory addresses noise of both types. The proposed associative memory performs as a bidirectional one-to-many or many-to-one associative memory and deals not only with bipolar data, but also with real-valued data. Results demonstrate that the proposed method's features are important for application to an intelligent robot operating in a real environment. The originality of our work consists of two points: employing a growing self-organizing network for an associative memory, and discussing what features are necessary for an associative memory for an intelligent robot and proposing an associative memory that satisfies those requirements.

Bayesian networks of age estimation and classification based on dental evidence: A study on the third molar mineralization.

Not only does the Bayesian approach offer a rational and logical environment for evidence evaluation in a forensic framework, but it also allows scientists to coherently deal with uncertainty related to a collection of multiple items of evidence, due to its flexible nature. Such flexibility might come at the expense of elevated computational complexity, which can be handled by using specific probabilistic graphical tools, namely Bayesian networks. In the current work, such probabilistic tools are used for evaluating dental evidence related to the development of third molars. A set of relevant properties characterizing the graphical models are discussed and Bayesian networks are implemented to deal with the inferential process laying beyond the estimation procedure, as well as to provide age estimates. Such properties include operationality, flexibility, coherence, transparence and sensitivity. A data sample composed of Italian subjects was employed for the analysis; results were in agreement with previous studies in terms of point estimate and age classification. The influence of the prior probability elicitation in terms of Bayesian estimate and classifies was also analyzed. Findings also supported the opportunity to take into consideration multiple teeth in the evaluative procedure, since it can be shown this results in an increased robustness towards the prior probability elicitation process, as well as in more favorable outcomes from a forensic perspective.

Patient and public involvement in reducing health and care research waste.

PubMed

Minogue, Virginia; Cooke, Mary; Donskoy, Anne-Laure; Vicary, Penny; Wells, Bill

2018-01-01

As much as 85 % of health research is believed to be wasted because it is not published or reported, the design is poor or does not consider what is already known in the topic area. Although a great deal of work has been done in the UK to reduce research waste, the role of patients and the public has not been discussed.This paper describes a survey, on the role of patients in reducing research waste, which was carried out as part of a larger piece of work on reducing waste in healthcare. The study found that patients were interested in reducing research waste. The key roles they play in research, for example being co-applicants for funding, members of project teams, co-researchers, means they have some shared responsibility for making sure the quality of research is high. This includes finding out what is already known about a topic and getting the study design right before seeking funding, publishing and reporting the results when the study is finished. Recognising where waste happens is part of good management of a research study. Background Eighty five per cent of health research expenditure is potentially wasted due to failure to publish research, unclear reporting of research that is published, and the failure of new research studies to systematically review previous research in the same topic area, poor study design and conduct. A great deal of progress has been made to address this issue but the role of patients and the public has not been considered. Main A small survey was undertaken, as part of a larger programme of work on reducing health and care waste, to understand the role of patients in reducing research waste. The study showed that patients are interested in this issue particularly in relation to the prioritisation of research and patient and public involvement. Conclusions Patients undertake key roles in the research process including co-applicancy, project management, or as co-researchers. This brings responsibility for ensuring high quality research and value for money. Responsibility for recognition of the potential for wasteful practices is part of the conduct and operation of research studies.

Relationship between ethical work climate and nurses' perception of organizational support, commitment, job satisfaction and turnover intent.

PubMed

Abou Hashish, Ebtsam Aly

2017-03-01

Healthcare organizations are now challenged to retain nurses' generation and understand why they are leaving their nursing career prematurely. Acquiring knowledge about the effect of ethical work climate and level of perceived organizational support can help organizational leaders to deal effectively with dysfunctional behaviors and make a difference in enhancing nurses' dedication, commitment, satisfaction, and loyalty to their organization. This study aims to determine the relationship between ethical work climate, and perceived organizational support and nurses' organizational commitment, job satisfaction, and turnover intention. A descriptive correlational research design was conducted in all inpatient care units at three major hospitals affiliated to different health sectors at Alexandria governorate. All nurses working in these previous hospitals were included in the study (N = 500). Ethical Climate Questionnaire, Survey of Perceived Organizational Support, Organizational Commitment Questionnaire, Index of Job Satisfaction, and Intention to Turnover scale were used to measure study variables. Ethical considerations: Approval was obtained from Ethics Committee at Faculty of Nursing, Alexandria University. Privacy and confidentiality of data were maintained and assured by obtaining subjects' informed consent to participate in the research before data collection. The result revealed positive significant correlations between nurses' perception of overall ethical work climate and each of perceived organizational support, commitment, as well as their job satisfaction. However, negative significant correlations were found between nurses' turnover intention and each of these variables. Also, approximately 33% of the explained variance of turnover intention is accounted by ethical work climate, organizational support, organizational commitment, and job satisfaction, and these variables independently contributed significantly in the prediction of turnover intention. Strategies to foster and enhance ethical and supportive work climates as well as job-related benefits are considered significant factors in increasing nurses' commitment and satisfaction and decreasing their turnover intention.

Kirsten, Laura; Butow, Phyllis; Price, Melanie; Hobbs, Kim; Sunquist, Kendra

2006-07-01

Cancer support groups are an important source of support for cancer patients, yet little is known about the challenges and training needs of both professionally trained and untrained leaders. The aim of this study was to discover the difficulties experienced and training desired by cancer support group leaders. Twenty-seven leaders of 34 cancer support groups participated in focus groups or individual interviews. Groups were purposively selected as representative of 173 support groups identified in New South Wales which were for adults with cancer and/or their adult carers and were not therapeutic or education-only groups. Difficulties identified included dealing with people's different communication styles and needs; dealing with recurrence, metastases and death; practical issues, including resources, setting the programme and funding security; maintaining personal balance and preventing burn out; establishing group credibility; dealing with group cycles; and leading groups in rural areas. Leaders also identified benefits and rewards from group leadership such as contributing to others' well-being, self-development and insight into others' lives. Non-professionally trained leaders experienced more difficulties, particularly in dealing with group process and practical issues. Difficulties identified were related both to working with a cancer population specifically and to working with groups in general. While some issues were common to both health professionals and non-health professionals, non-health professionals reported greater supportive needs. Clear guidelines, targeted training and development of better methods of support to reduce the stress and burn out experienced by group leaders are needed.

50% off or buy one get one free? Frame preference as a function of consumable nature in dairy products.

PubMed

Li, Shu; Sun, Yan; Wang, Yong

2007-08-01

Previous studies on how framing differentially affects consumer perceptions of value from equivalent deals indicate that perceptions of deal value from price-saving versus extra-product promotions are moderated by the stock-up characteristic of the category. In this study, the authors explored the relationship between stock-up characteristic and frame preference and the influence of the consumable nature of goods on frame preference. An experiment involving 223 student participants showed that consumable nature, but not stock-up characteristic, affected frame preference. The authors discuss the implications of this finding for the study of information framing and how it impacts consumer judgment and decision making.

Impact of conflict and violence on workers in a hospital emergency room.

PubMed

Lancman, Selma; Mângia, Elisabete Ferreira; Muramoto, Melissa Tieko

2013-01-01

Emergency room (ER) work includes dealing with situations of conflict and aggression. The diversity and unpredictability of these situations and the lack of pre-established procedures to guide workers in dealing with these phenomena affect and weaken their physical and mental health. The purpose of the article is to learn about conflict and aggression at work and its impact on the workers in a hospital emergency room. The method is a transversal, exploratory, descriptive and observational study, carried out from September to November 2008, using direct observation procedures and interviews. Two hundred and eighty emergency room workers participated in the observations and eleven interviews were carried out with workers from several professional categories. The work process is marked by overload, individualization of responsibilities, time pressures and deadlines for making decision, little space for exchange and sharing, lack of support or guidance. The strong pressure to provide care quickly causes conflict and aggression among users and the different professional teams. These situations arise from problems in work organization and users in excess of the ER service capacity. The article recommends changes in the work process that can simultaneously improve both the quality of care for patients and provide protective measures for workers.

Dealing with malaria in the last 60 years. A personal experience.

PubMed

de Zulueta, J

2000-06-01

Dealing with malaria in the last 60 years is seen by the author in the perspective of his own experience. His malaria work, which began in 1941, covered the study of the habits of the mosquitoes dwelling in the savanna country of Eastern Colombia and the effect on malaria transmission of the newly introduced DDT residual spraying. The success of the campaign he later directed in Sarawak and Brunei contributed to the launching by WHO of its global malaria eradication campaign. Further successful work in Uganda showed the possibility of effective control and even eradication in highland country but left unsolved the problem of how to interrupt transmission of holoendemic malaria in Africa. The author's work with WHO in the Middle East showed to what extent social and economic conditions could influence the course of a malaria campaign. This was also the experience in America, both in Colombia in the author's early work and later in Mexico during an evaluation of the national malaria programme. Development of insecticide resistance was also encountered in his career and the refractoriness of the European vectors was also observed in his work as a malariologist.

An algebra of discrete event processes

NASA Technical Reports Server (NTRS)

Heymann, Michael; Meyer, George

1991-01-01

This report deals with an algebraic framework for modeling and control of discrete event processes. The report consists of two parts. The first part is introductory, and consists of a tutorial survey of the theory of concurrency in the spirit of Hoare's CSP, and an examination of the suitability of such an algebraic framework for dealing with various aspects of discrete event control. To this end a new concurrency operator is introduced and it is shown how the resulting framework can be applied. It is further shown that a suitable theory that deals with the new concurrency operator must be developed. In the second part of the report the formal algebra of discrete event control is developed. At the present time the second part of the report is still an incomplete and occasionally tentative working paper.

Integrated language education - a means of enhancing engineers' social competences

NASA Astrophysics Data System (ADS)

Lappalainen, P.

2010-08-01

The changes facing industries are necessitating a concomitant change in university curriculum. Before instigating a reform, however, education providers need to acquire an understanding of the most pertinent development needs essential for filling industrial competence gaps. The Language Centre at the Helsinki University of Technology in Finland set out to respond to the emerging competence demands by examining industrial requirements through previous research and stakeholder analyses. Surveys conducted among employers and students corroborated a need to shift focus towards oral communication abilities. More specifically, university education needs to address interaction skills essential in meetings and managerial tasks. As a result, a so-called integrated language course was designed and piloted to train students into multi-disciplinary, culturally and ethically aware communicators who possess leveraged self-leadership and managerial abilities. 'Organisational Communications' integrates substance matters such as finance, strategy, leadership and ethics into a language course, while harnessing the English language as a tool. Course methodology is based on project- and problem-based learning and situational learning, rooting the students in real working life by imitating authentic corporate cases and industrial contexts. The course aims to provide the students with preparedness, ability and mindset to deal with working life challenges and ways of working while applying their specialist discourse, that is, the appropriate industrial jargon and linguistic practices. The learning outcomes and student feedback from this course indicate that the pedagogy in use in this experiment, drawing from exercises emulating authentic, industrial problems, offers an effective method of preparing students for working life requirements.

Top-pair production and decay at NLO matched with parton showers

DOE PAGES

Campbell, John M.; Ellis, R. Keith; Nason, Paolo; ...

2015-04-21

We present a next-to-leading order (NLO) calculation of tt¯ production in hadronic collisions interfaced to shower generators according to the POWHEG method. We start from an NLO result from previous work, obtained in the zero width limit, where radiative corrections to both production and decays are included. The POWHEG interface required an extension of the POWHEG BOX framework, in order to deal with radiation from the decay of resonances. This extension is fully general (i.e. it can be applied in principle to any process considered in the zero width limit), and is here applied for the first time. In ordermore » to perform a realistic simulation, we introduce finite width effects using different approximations, that we validated by comparing with published exact NLO results. We have interfaced our POWHEG code to the PYTHIA8 shower Monte Carlo generator. At this stage, we dealt with novel issues related to the treatment of resonances, especially with regard to the initial scale for the shower that needs to be set appropriately. This procedure affects, for example, the fragmentation function of the b quark, that we have studied with particular attention. We believe that the tool presented here improves over previous generators for all aspects that have to do with top decays, and especially for the study of issues related to top mass measurements that involve B hadrons or b jets. As a result, the work presented here also constitutes a first step towards a fully consistent matching of NLO calculations involving intermediate resonances decaying into coloured particles, with parton showers.« less

[Health management as part of leadership in public administration].

PubMed

Matyssek, A K

2012-02-01

Leadership includes two tasks within public administration: leading employees by creating healthy working conditions and being led by others. The basis of leading others in a healthy way means dealing with oneself in a healthy manner; this includes typical healthy behavior (i.e., physical activity, improved nutrition, not smoking), which allows for recovery by a good work-life balance and a sensitive dealing with one's own limits. Given these conditions of healthy self care, managers are able to act as role models and lead their employees in a healthy manner. Leading in a healthy manner means showing appreciation, being interested in the employees ("caring"), integrating them in decision-making, allowing transparency, improving the working atmosphere, and finally reducing stress and increasing resources. The latter includes social support, which decreases the danger of employees burning out. The article presents the concept of a 2-day training that is designed for managers in order to raise their awareness for duties related to health management in public administration.

"I wish he hadn't told me that": methodological and ethical issues in social trauma and conflict research.

PubMed

Chaitin, Julia

2003-10-01

Undertaking research on individuals who have experienced social traumas, such as being a victim or perpetrator of genocides and wars, presents difficult decisions for qualitative researchers. Deciding how to deal with these issues becomes more problematic when the researcher is a member of the society in conflict. To do this work, and to work collaboratively with researchers from the other side, sensitive ways to collect data have to be chosen. Interpretations of the materials can be no less difficult: Analyses often lead to information and understandings that may be difficult for the researcher to deal with from ethical, moral, and personal standpoints, especially when he or she is a member of the society and culture under study. In this keynote address, the author explores methodological and ethical issues connected to these topics. She brings examples from her work on the Palestinian-Israeli conflict and focuses on use of the life story methodology.

Dealing with task interruptions in complex dynamic environments: are two heads better than one?

PubMed

Tremblay, Sébastien; Vachon, François; Lafond, Daniel; Kramer, Chelsea

2012-02-01

This study examined whether teaming up mitigates individual vulnerability to task interruptions in complex dynamic situations. Omnipresent in everyday multitasking environments, task interruptions are usually detrimental to individual performance. This is particularly crucial in dynamic command and control (C2) safety-critical contexts because of the additional challenge imposed by the continually evolving situation during the interruption. We employed a firefighting microworld to simulate C2 in the context of supervisory control to examine the relative impact of interruptions on participants working in a functional dyad versus operators working alone. Although task interruption was detrimental to participants' efficacy of monitoring resources, the negative impact of interruption was reduced for those working in teams. Teaming up translated into faster resumption time, but only if both teammates were interrupted simultaneously. Interrupting only one team member was associated with increased postinterruption communications and slower resumption time. These findings suggest that in complex dynamic situations working in a small team confers more resistance to task interruption than working alone by virtue of the reduced individual workload typical of teamwork. The benefit of collaborative work seems nevertheless mediated by the coordination and communication overhead associated with teamwork. The present findings have practical implications for operators dealing with unexpected events such as task interruptions in C2 environments.

The main goal of the working group was to present the state-of-the-art of Higgs physics at the LHC, integrating all new results that have appeared in the last few years. The first part compiles the most up-to-date predictions of Higgs boson production cross sections and decay branching ratios, parton distribution functions, and off-shell Higgs boson production and interference effects. The second part discusses the recent progress in Higgs effective field theory predictions, followed by the third part on pseudo-observables, simplifiedmore » template cross section and fiducial cross section measurements, which give the baseline framework for Higgs boson property measurements. The fourth part deals with the beyond the Standard Model predictions of various benchmark scenarios of Minimal Supersymmetric Standard Model, extended scalar sector, Next-to-Minimal Supersymmetric Standard Model and exotic Higgs boson decays. This report follows three previous working-group reports: Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002), Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002), and Handbook of LHC Higgs Cross Sections: 3. Higgs properties (CERN-2013-004). The current report serves as the baseline reference for Higgs physics in LHC Run 2 and beyond.« less

Job satisfaction in nursing: a concept analysis study.

PubMed

Liu, Y; Aungsuroch, Y; Yunibhand, J

2016-03-01

This study aims to undertake a concept analysis of job satisfaction in the nursing profession. Around current global shortage of nurses, it is important to stabilize the nursing workforce. Nurses' job satisfaction has been found to be related to intention to leave. In the nursing profession, there is a lack of evidence to support the attributes of nurses' job satisfaction. Walker and Avant's approach of concept analysis was used. The main attributes of job satisfaction from this study are (1) fulfillment of desired needs within the work settings, (2) happiness or gratifying emotional responses towards working conditions, and (3) job value or equity. These attributes are influenced by antecedent conditions like demographic, emotional, work characteristics and environmental variables. Additionally, the consequences of nurses' job satisfaction have a significant impact on both nurses and patients. This study integrated both the content and process of motivational theories to generate the attributes of job satisfaction in nursing that overcome the limitation of the previous studies, which looked only at the definitions of nurses' job satisfaction based on content motivational theories. The findings of this study can facilitate both nursing researchers to develop a cultural adaption instrument and policy makers to improve clinical nursing practice. This analysis provides nurse managers with a new perspective to deal with nurses' job satisfaction by taking into account all the attributes that influence it in the nursing field. © 2015 International Council of Nurses.

Conte, G.; Zanoli, S.M.

1994-12-31

This paper concerns the development of a sonar-based navigation and guidance system for underwater, unmanned vehicles. In particular, the authors describe and discuss an obstacle avoidance procedure that is capable of dealing with situations involving several obstacles. The main features of the system are the use of a Kalman filter, both for estimating data and for predicting the evolution of the observed scene, and the possibility of working at different levels of data abstraction. The system has shown satisfactory performances in dealing with moving obstacles in general situations.

GEANT4 Tuning For pCT Development

NASA Astrophysics Data System (ADS)

Yevseyeva, Olga; de Assis, Joaquim T.; Evseev, Ivan; Schelin, Hugo R.; Paschuk, Sergei A.; Milhoretto, Edney; Setti, João A. P.; Díaz, Katherin S.; Hormaza, Joel M.; Lopes, Ricardo T.

Proton beams in medical applications deal with relatively thick targets like the human head or trunk. Thus, the fidelity of proton computed tomography (pCT) simulations as a tool for proton therapy planning depends in the general case on the accuracy of results obtained for the proton interaction with thick absorbers. GEANT4 simulations of proton energy spectra after passing thick absorbers do not agree well with existing experimental data, as showed previously. Moreover, the spectra simulated for the Bethe-Bloch domain showed an unexpected sensitivity to the choice of low-energy electromagnetic models during the code execution. These observations were done with the GEANT4 version 8.2 during our simulations for pCT. This work describes in more details the simulations of the proton passage through aluminum absorbers with varied thickness. The simulations were done by modifying only the geometry in the Hadrontherapy Example, and for all available choices of the Electromagnetic Physics Models. As the most probable reasons for these effects is some specific feature in the code, or some specific implicit parameters in the GEANT4 manual, we continued our study with version 9.2 of the code. Some improvements in comparison with our previous results were obtained. The simulations were performed considering further applications for pCT development.

A Hierarchical Model Predictive Tracking Control for Independent Four-Wheel Driving/Steering Vehicles with Coaxial Steering Mechanism

NASA Astrophysics Data System (ADS)

Itoh, Masato; Hagimori, Yuki; Nonaka, Kenichiro; Sekiguchi, Kazuma

2016-09-01

In this study, we apply a hierarchical model predictive control to omni-directional mobile vehicle, and improve the tracking performance. We deal with an independent four-wheel driving/steering vehicle (IFWDS) equipped with four coaxial steering mechanisms (CSM). The coaxial steering mechanism is a special one composed of two steering joints on the same axis. In our previous study with respect to IFWDS with ideal steering, we proposed a model predictive tracking control. However, this method did not consider constraints of the coaxial steering mechanism which causes delay of steering. We also proposed a model predictive steering control considering constraints of this mechanism. In this study, we propose a hierarchical system combining above two control methods for IFWDS. An upper controller, which deals with vehicle kinematics, runs a model predictive tracking control, and a lower controller, which considers constraints of coaxial steering mechanism, runs a model predictive steering control which tracks the predicted steering angle optimized an upper controller. We verify the superiority of this method by comparing this method with the previous method.

Astrophysical applications of the post-Tolman-Oppenheimer-Volkoff formalism

NASA Astrophysics Data System (ADS)

Glampedakis, Kostas; Pappas, George; Silva, Hector O.; Berti, Emanuele

2016-08-01

The bulk properties of spherically symmetric stars in general relativity can be obtained by integrating the Tolman-Oppenheimer-Volkoff (TOV) equations. In previous work [K. Glampedakis, G. Pappas, H. O. Silva, and E. Berti, Phys. Rev. D 92, 024056 (2015)], we developed a "post-TOV" formalism—inspired by parametrized post-Newtonian theory—which allows us to classify in a parametrized, phenomenological form all possible perturbative deviations from the structure of compact stars in general relativity that may be induced by modified gravity at second post-Newtonian order. In this paper we extend the formalism to deal with the stellar exterior, and we compute several potential astrophysical observables within the post-TOV formalism: the surface redshift zs, the apparent radius Rapp, the Eddington luminosity at infinity LE∞ and the orbital frequencies. We show that, at leading order, all of these quantities depend on just two post-TOV parameters μ1 and χ , and we discuss the possibility to measure (or set upper bounds on) these parameters.

Analysis of Feeder Bus Network Design and Scheduling Problems

PubMed Central

Almasi, Mohammad Hadi; Karim, Mohamed Rehan

2014-01-01

A growing concern for public transit is its inability to shift passenger's mode from private to public transport. In order to overcome this problem, a more developed feeder bus network and matched schedules will play important roles. The present paper aims to review some of the studies performed on Feeder Bus Network Design and Scheduling Problem (FNDSP) based on three distinctive parts of the FNDSP setup, namely, problem description, problem characteristics, and solution approaches. The problems consist of different subproblems including data preparation, feeder bus network design, route generation, and feeder bus scheduling. Subsequently, descriptive analysis and classification of previous works are presented to highlight the main characteristics and solution methods. Finally, some of the issues and trends for future research are identified. This paper is targeted at dealing with the FNDSP to exhibit strategic and tactical goals and also contributes to the unification of the field which might be a useful complement to the few existing reviews.

Workplace violence in healthcare settings: risk factors and protective strategies.

PubMed

Gillespie, Gordon Lee; Gates, Donna M; Miller, Margaret; Howard, Patricia Kunz

2010-01-01

This article describes the risk factors and protective strategies associated with workplace violence perpetrated by patients and visitors against healthcare workers. Perpetrator risk factors for patients and visitors in healthcare settings include mental health disorders, drug or alcohol use, inability to deal with situational crises, possession of weapons, and being a victim of violence. Worker risk factors are gender, age, years of experience, hours worked, marital status, and previous workplace violence training. Setting and environmental risk factors for experiencing workplace violence include time of day and presence of security cameras. Protective strategies for combating the negative consequences of workplace violence include carrying a telephone, practicing self-defense, instructing perpetrators to stop being violent, self- and social support, and limiting interactions with potential or known perpetrators of violence. Workplace violence is a serious and growing problem that affects all healthcare professionals. Strategies are needed to prevent workplace violence and manage the negative consequences experienced by healthcare workers following violent events.

A Route to Well-being: Intelligence vs. Wise Reasoning

PubMed Central

Grossmann, Igor; Na, Jinkyung; Varnum, Michael E.W.; Kitayama, Shinobu; Nisbett, Richard E.

2012-01-01

Laypeople and many social scientists assume that superior reasoning abilities lead to greater well-being. However, previous research has been inconclusive. This may be because prior investigators used operationalizations of reasoning that favored analytic as opposed to wise thinking. We assessed wisdom in terms of the degree to which people use various pragmatic schemas to deal with social conflicts. With a random sample of Americans we found that wise reasoning is associated with greater life satisfaction, less negative affect, better social relationships, less depressive rumination, more positive vs. negative words used in speech, and greater longevity. The relationship between wise reasoning and well-being held even when controlling for socio-economic factors, verbal abilities, and several personality traits. As in prior work there was no association between intelligence and well-being. Further, wise reasoning mediated age-related differences in well-being, particularly among the middle-aged and older adults. Implications for research on reasoning, well-being and aging are discussed. PMID:22866683

Life at the State summit: views and experiences of 18 psychiatric leaders.

PubMed

Gaver, K D; Norman, M L; Greenblatt, M

1984-03-01

In 1981 the American Psychiatric Association appointed an ad hoc committee to investigate the decline of psychiatrist leadership of public mental health programs. As part of the committee's research, the 18 psychiatrists who were then state commissioners or directors of mental health were surveyed on how they got their jobs and on their backgrounds, present responsibilities, support systems, and future plans. The results of the survey are discussed and presented in tabular format. The psychiatrists surveyed recommended that future commissioners have backgrounds similar to their own, which consisted of a great deal of previous on-the-job experience in mental health administration but little formal training or education in administration; none of the commissioners had obtained APA certification in administrative psychiatry. The commissioners felt they received the most support in their work from their subordinates; among the major groups listed as providing support, APA ranked lowest. The authors discuss the implications of the survey findings as well as issues surrounding the administration of public mental health programs by psychiatrists.

Specific aspects of eating disorders, exercise addiction, chronic traumatic encephalopathy and mood disorders in the context of overtraining syndrome are examined. In particular, the interrelationship between life and work characteristics unique to elite athletes and the development of mental disorders are reviewed. Differences of clinical presentation and some therapeutic consequences are discussed. The authors suggest that the physical and mental strains endured by elite athletes might influence the onset and severity of their psychiatric disorder. Beside the existing research strategies dealing with the amount of exercise, its intensity and lack of recreation experienced by athletes, further research on psycho-social factors is needed to better understand the sport-specific aetiology of mental disorders in high-performance athletes.

Synchronization of coupled stochastic complex-valued dynamical networks with time-varying delays via aperiodically intermittent adaptive control

Wang, Pengfei; Jin, Wei; Su, Huan

2018-04-01

This paper deals with the synchronization problem of a class of coupled stochastic complex-valued drive-response networks with time-varying delays via aperiodically intermittent adaptive control. Different from the previous works, the intermittent control is aperiodic and adaptive, and the restrictions on the control width and time delay are removed, which lead to a larger application scope for this control strategy. Then, based on the Lyapunov method and Kirchhoff's Matrix Tree Theorem as well as differential inequality techniques, several novel synchronization conditions are derived for the considered model. Specially, impulsive control is also considered, which can be seen as a special case of the aperiodically intermittent control when the control width tends to zero. And the corresponding synchronization criteria are given as well. As an application of the theoretical results, a class of stochastic complex-valued coupled oscillators with time-varying delays is studied, and the numerical simulations are also given to demonstrate the effectiveness of the control strategies.

The frequency and features of malpractice lawsuits against dentists in Chile are not well known. To determine the magnitude and frequency of professional liability claims against dentists. A retrospective analysis of the Medical Liability Unit of the Legal Medical Service of Chile database. This public organization deals with most professional liability claims in Chile. Between 2007 and 2012, 3,990 expert opinions about liability of health care professionals were requested. Odontology was the fifth specialty most commonly sued and dentists, the second most frequently sued professionals. Sixty nine percent of cases originated in private clinics, which is coincident with a higher frequency of dentists working in private practice. Most petitioners were adult women and most claims originated from surgical interventions and infections. In 35% of claims against dentists, a violation of Lex Artis was confirmed, compared with 9% of all expert opinions that generated in the unit. Claims against dentists are more common than previously thought and these professionals should adopt preventive measures to avoid them.

Variationally Optimized Free-Energy Flooding for Rate Calculation.

PubMed

McCarty, James; Valsson, Omar; Tiwary, Pratyush; Parrinello, Michele

2015-08-14

We propose a new method to obtain kinetic properties of infrequent events from molecular dynamics simulation. The procedure employs a recently introduced variational approach [Valsson and Parrinello, Phys. Rev. Lett. 113, 090601 (2014)] to construct a bias potential as a function of several collective variables that is designed to flood the associated free energy surface up to a predefined level. The resulting bias potential effectively accelerates transitions between metastable free energy minima while ensuring bias-free transition states, thus allowing accurate kinetic rates to be obtained. We test the method on a few illustrative systems for which we obtain an order of magnitude improvement in efficiency relative to previous approaches and several orders of magnitude relative to unbiased molecular dynamics. We expect an even larger improvement in more complex systems. This and the ability of the variational approach to deal efficiently with a large number of collective variables will greatly enhance the scope of these calculations. This work is a vindication of the potential that the variational principle has if applied in innovative ways.

The importance of the boundary condition in the transport of intensity equation based phase measurement

NASA Astrophysics Data System (ADS)

Zhang, Jialin; Chen, Qian; Li, Jiaji; Zuo, Chao

2017-02-01

The transport of intensity equation (TIE) is a powerful tool for direct quantitative phase retrieval in microscopy imaging. However, there may be some problems when dealing with the boundary condition of the TIE. The previous work introduces a hard-edged aperture to the camera port of the traditional bright field microscope to generate the boundary signal for the TIE solver. Under this Neumann boundary condition, we can obtain the quantitative phase without any assumption or prior knowledge about the test object and the setup. In this paper, we will demonstrate the effectiveness of this method based on some experiments in practice. The micro lens array will be used for the comparison of two TIE solvers results based on introducing the aperture or not and this accurate quantitative phase imaging technique allows measuring cell dry mass which is used in biology to follow cell cycle, to investigate cell metabolism, or to address effects of drugs.

Dynamic node immunization for restraint of harmful information diffusion in social networks

NASA Astrophysics Data System (ADS)

Yang, Dingda; Liao, Xiangwen; Shen, Huawei; Cheng, Xueqi; Chen, Guolong

2018-08-01

To restrain the spread of harmful information is crucial for the healthy and sustainable development of social networks. We address the problem of restraining the spread of harmful information by immunizing nodes in the networks. Previous works have developed methods based on the network topology or studied how to immunize nodes in the presence of initial infected nodes. These static methods, in which nodes are immunized at once, may have poor performance in the certain situation due to the dynamics of diffusion. To tackle this problem, we introduce a new dynamic immunization problem of immunizing nodes during the process of the diffusion in this paper. We formulate the problem and propose a novel heuristic algorithm by dealing with two sub-problems: (1) how to select a node to achieve the best immunization effect at the present time? (2) whether the selected node should be immunized right now? Finally, we demonstrate the effectiveness of our algorithm through extensive experiments on various real datasets.

Integration Of Heat Transfer Coefficient In Glass Forming Modeling With Special Interface Element

NASA Astrophysics Data System (ADS)

Moreau, P.; César de Sá, J.; Grégoire, S.; Lochegnies, D.

2007-05-01

Numerical modeling of the glass forming processes requires the accurate knowledge of the heat exchange between the glass and the forming tools. A laboratory testing is developed to determine the evolution of the heat transfer coefficient in different glass/mould contact conditions (contact pressure, temperature, lubrication…). In this paper, trials are performed to determine heat transfer coefficient evolutions in experimental conditions close to the industrial blow-and-blow process conditions. In parallel of this work, a special interface element is implemented in a commercial Finite Element code in order to deal with heat transfer between glass and mould for non-meshing meshes and evolutive contact. This special interface element, implemented by using user subroutines, permits to introduce the previous heat transfer coefficient evolutions in the numerical modelings at the glass/mould interface in function of the local temperatures, contact pressures, contact time and kind of lubrication. The blow-and-blow forming simulation of a perfume bottle is finally performed to assess the special interface element performance.

Geometric stiffening in multibody dynamics formulations

NASA Technical Reports Server (NTRS)

Sharf, Inna

1993-01-01

In this paper we discuss the issue of geometric stiffening as it arises in the context of multibody dynamics. This topic has been treated in a number of previous publications in this journal and appears to be a debated subject. The controversy revolves primarily around the 'correct' methodology for incorporating the stiffening effect into dynamics formulations. The main goal of this work is to present the different approaches that have been developed for this problem through an in-depth review of several publications dealing with this subject. This is done with the goal of contributing to a precise understanding of the existing methodologies for modelling the stiffening effects in multibody systems. Thus, in presenting the material we attempt to illuminate the key characteristics of the various methods as well as show how they relate to each other. In addition, we offer a number of novel insights and clarifying interpretations of these schemes. The paper is completed with a general classification and comparison of the different approaches.

Combining pressure and temperature control in dynamics on energy landscapes

NASA Astrophysics Data System (ADS)

Hoffmann, Karl Heinz; Christian Schön, J.

2017-05-01

Complex systems from science, technology or mathematics usually appear to be very different in their specific dynamical evolution. However, the concept of an energy landscape with its basins corresponding to locally ergodic regions separated by energy barriers provides a unifying approach to the description of complex systems dynamics. In such systems one is often confronted with the task to control the dynamics such that a certain basin is reached with the highest possible probability. Typically one aims for the global minimum, e.g. when dealing with global optimization problems, but frequently other local minima such as the metastable compounds in materials science are of primary interest. Here we show how this task can be solved by applying control theory using magnesium fluoride as an example system, where different modifications of MgF2 are considered as targets. In particular, we generalize previous work restricted to temperature controls only and present controls which simultaneously adjust temperature and pressure in an optimal fashion.

Effects of cognitive appraisal and mental workload factors on performance in an arithmetic task.

PubMed

Galy, Edith; Mélan, Claudine

2015-12-01

We showed in a previous study an additive interaction between intrinsic and extraneous cognitive loads and of participants' alertness in an 1-back working memory task. The interaction between intrinsic and extraneous cognitive loads was only observed when participants' alertness was low (i.e. in the morning). As alertness is known to reflect an individual's general functional state, we suggested that the working memory capacity available for germane cognitive load depends on a participant's functional state, in addition to intrinsic and extraneous loads induced by the task and task conditions. The relationships between the different load types and their assessment by specific load measures gave rise to a modified cognitive load model. The aim of the present study was to complete the model by determining to what extent and at what processing level an individual's characteristics intervene in order to implement efficient strategies in a working memory task. Therefore, the study explored participants' cognitive appraisal of the situation in addition to the load factors considered previously-task difficulty, time pressure and alertness. Each participant performed a mental arithmetic task in four different cognitive load conditions (crossover of two task difficulty conditions and of two time pressure conditions), both while their alertness was low (9 a.m.) and high (4 p.m.). Results confirmed an additive effect of task difficulty and time pressure, previously reported in the 1-back memory task, thereby lending further support to the modified cognitive load model. Further, in the high intrinsic and extraneous load condition, performance was reduced on the morning session (i.e. when alertness was low) on one hand, and in those participants' having a threat appraisal of the situation on the other hand. When these factors were included into the analysis, a performance drop occurred in the morning irrespective of cognitive appraisal, and with threat appraisal in the afternoon (i.e. high alertness). Taken together, these findings indicate that mental overload can be the result of a combination of subject-related characteristics, including alertness and cognitive appraisal, in addition to well-documented task-related components (intrinsic and extraneous load). As the factors investigated in the study are known to be critically involved in a number of real job-activities, the findings suggest that solutions designed to reduce incidents and accidents at work should consider the situation from a global perspective, including individual characteristics, task parameters, and work organization, rather than dealing with each factor separately.

Dusting off the epidemiological triad: could it work with obesity?

PubMed

Egger, G; Swinburn, B; Rossner, S

2003-05-01

The search for effective ways of dealing with obesity has centred on biological research and clinical management. However, obesity needs to be conceptualized more broadly if the modern pandemic is to be arrested. The epidemiological triad (hosts, agent/vectors and environments) has served us well in dealing with epidemics in the past, and may be worth re-evaluating to this end. Education, behaviour change and clinical practices deal predominantly with the host, although multidisciplinary practices such as shared-care might also be expected to impact on other corners of the triad. Technology deals best with the agent of obesity (energy imbalance) and it's vectors (excessive energy intake and/or inadequate energy expenditure), and policy and social change are needed to cope with the environment. The value of a broad model like this, rather than specific isolated approaches, is that the key players such as legislators, health professionals, governments and industry can see their roles in attenuating and eventually reversing the epidemic. It also highlights the need to intervene at all levels in obesity control and reduces the relevance of arguments about nature vs. nurture.

Prehospital chemical restraint of a noncommunicative autistic minor by law enforcement.

2012-01-01

When responders are dealing with an agitated patient in the field, safety for all involved may sometimes only be accomplished with physical or chemical restraints. While experiences using chemical restraint in the prehospital setting are found in the medical literature, the use of this by law enforcement as a first-response restraint has not previously been described. We report a case of successful law enforcement-administered sedation of a noncommunicative, autistic, and violent minor using intramuscular droperidol and diphenhydramine. Although this case has some unique characteristics that allowed chemical restraint to be given by the law enforcement agency, it calls attention to some specific prehospital issues that need to be addressed when dealing with autistic patients with extreme agitation.

Mental ill-health among adult patients at healthcare centres in Sweden: district nurses experiences.

PubMed

Janlöv, Ann-Christin; Johansson, Linda; Clausson, Eva K

2017-11-13

Mental ill-health among the general population is increasing in Sweden. Primary Health Care (PHC) and Healthcare Centres (HCC), where district nurses (DNs) work, bear the basic responsibility for treatment of mental ill-health, while severe mental ill-health fall under the responsibility of psychiatric specialist care. The increased prevalence of mental ill-health in the community means that DNs increasingly encounter people with mental health problems - not least as a comorbidity. How well DNs are equipped to deal with mental ill-health is currently unclear. The purpose of this study was to explore district nurses' experience of encountering and dealing with mental ill-health among adult patients at healthcare centres. A qualitative explorative approach was used to capture the experiences of the phenomena under study. Individual interviews were conducted with 10 DNs working at six HCCs. The interviews were transcribed and analysed by qualitative content analysis. The result emerged as several subcategories captured by three categories: (i) having competence - a prerequisite for feeling confident; (ii) nursing mental ill-health requires time and commitment; and (iii) working in an organisation without preparedness, encompassed by the synthesising theme; nursing mental ill-health requires specific competence and organisational support. Working as a DN requires formal and informal competence when encountering patients with complex health needs. The findings revealed that the DNs could feel insecure regarding how to deal with patients with mental ill-health due to lack of knowledge. Assessment of patients with mental ill-health is time- and energy-consuming and calls for improved teamwork at HCCs as well as effective collaboration with psychiatric specialist care and other care givers. The DNs responsibility to fulfil their work considering the increasing number of mental ill-health among people that seeks help at HCCs needs to be acknowledged and met by the PHC organisation. © 2017 The Authors.

Toward an optimal online checkpoint solution under a two-level HPC checkpoint model

DOE PAGES

Di, Sheng; Robert, Yves; Vivien, Frederic; ...

2016-03-29

The traditional single-level checkpointing method suffers from significant overhead on large-scale platforms. Hence, multilevel checkpointing protocols have been studied extensively in recent years. The multilevel checkpoint approach allows different levels of checkpoints to be set (each with different checkpoint overheads and recovery abilities), in order to further improve the fault tolerance performance of extreme-scale HPC applications. How to optimize the checkpoint intervals for each level, however, is an extremely difficult problem. In this paper, we construct an easy-to-use two-level checkpoint model. Checkpoint level 1 deals with errors with low checkpoint/recovery overheads such as transient memory errors, while checkpoint level 2more » deals with hardware crashes such as node failures. Compared with previous optimization work, our new optimal checkpoint solution offers two improvements: (1) it is an online solution without requiring knowledge of the job length in advance, and (2) it shows that periodic patterns are optimal and determines the best pattern. We evaluate the proposed solution and compare it with the most up-to-date related approaches on an extreme-scale simulation testbed constructed based on a real HPC application execution. Simulation results show that our proposed solution outperforms other optimized solutions and can improve the performance significantly in some cases. Specifically, with the new solution the wall-clock time can be reduced by up to 25.3% over that of other state-of-the-art approaches. Lastly, a brute-force comparison with all possible patterns shows that our solution is always within 1% of the best pattern in the experiments.« less

Management of everyday work in Emergency Departments - an exploratory study with Swedish Managers.

PubMed

Andersson, Henrik; Wireklint Sundström, Birgitta; Nilsson, Kerstin; Jakobsson Ung, Eva

2014-10-01

Through their formal mandate, position and authority, managers are responsible for managing everyday work in Emergency Departments (EDs) as well as striving for excellence and dealing with the individual needs of practitioners and patients. The aim of the present study is to explore managers' experiences of managing everyday work in Swedish EDs. A qualitative and exploratory design has been used in this study. Seven managers were interviewed at two EDs. Data was analysed using qualitative content analysis with focus on latent content. Managers experience everyday work in the ED as lifesaving work. One of the characteristics of their approach to everyday work is their capability for rapidly identifying patients with life-threatening conditions and for treating them accordingly. The practitioners are on stand-by in order to deal with unexpected situations. This implies having to spend time waiting for the physicians' decisions. Management is characterised by a command and control approach. The managers experience difficulties in meeting the expectations of their staff. They strive to be proactive but instead they become reactive since the prevailing medical, bureaucratic and production-orientated systems constrain them. The managers demonstrate full compliance with the organisational systems. This threatens to reduce their freedom of action and influences the way they perform their managerial duties within and outside the EDs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Bullying in nursing and ways of dealing with it.

PubMed

Lowenstein, Ludwig F

As with many other professions, nursing has its share of bullies who discredit the profession, while other nurses work with dedicated efficiency and good will. Bullying has an impact on the workplace environment and nurses in general; it can cause low morale and in some cases can make nurses seek employment elsewhere or even leave the profession. This article considers recent research into bullying in the workplace, including its prevalence within the profession, causes and identification, as well as different types of bullying and its impact on victims. It also highlights research into combating, preventing and dealing with the problem.

A new mean estimator using auxiliary variables for randomized response models

NASA Astrophysics Data System (ADS)

Ozgul, Nilgun; Cingi, Hulya

2013-10-01

Randomized response models are commonly used in surveys dealing with sensitive questions such as abortion, alcoholism, sexual orientation, drug taking, annual income, tax evasion to ensure interviewee anonymity and reduce nonrespondents rates and biased responses. Starting from the pioneering work of Warner [7], many versions of RRM have been developed that can deal with quantitative responses. In this study, new mean estimator is suggested for RRM including quantitative responses. The mean square error is derived and a simulation study is performed to show the efficiency of the proposed estimator to other existing estimators in RRM.

1991-01-01

The Space Network Interoperability Panel (SNIP) study is a tripartite study that involves the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and the National Space Development Agency (NASDA) of Japan. SNIP involves an ongoing interoperability study of the Data Relay Satellite (DRS) Systems of the three organizations. The study is broken down into two parts; Phase one deals with S-band (2 GHz) interoperability and Phase two deals with Ka-band (20/30 GHz) interoperability (in addition to S-band). In 1987 the SNIP formed a Working Group to define and study operations concepts and technical subjects to assure compatibility of the international data relay systems. Since that time a number of Panel and Working Group meetings have been held to continue the study. Interoperability is of interest to the three agencies because it offers a number of potential operation and economic benefits. This paper presents the history and status of the SNIP study.

2015-01-01

Traditional efforts to deal with the enormous problem of workplace safety have proved insufficient, as they have tended to neglect the broader sociotechnical environment that surrounds workers. Here, we advocate a sociotechnical systems approach that describes the complex multi-level system factors that contribute to workplace safety. From the literature on sociotechnical systems, complex systems and safety, we develop a sociotechnical model of workplace safety with concentric layers of the work system, socio-organisational context and the external environment. The future challenges that are identified through the model are highlighted. Practitioner Summary: Understanding the environmental, organisational and work system factors that contribute to workplace safety will help to develop more effective and integrated solutions to deal with persistent workplace safety problems. Solutions to improve workplace safety need to recognise the broad sociotechnical system and the respective interactions between the system elements and levels. PMID:25831959

Remote sensing programs and courses in engineering and water resources

Kiefer, R. W.

1981-01-01

The content of typical basic and advanced remote sensing and image interpretation courses are described and typical remote sensing graduate programs of study in civil engineering and in interdisciplinary environmental remote sensing and water resources management programs are outlined. Ideally, graduate programs with an emphasis on remote sensing and image interpretation should be built around a core of five courses: (1) a basic course in fundamentals of remote sensing upon which the more specialized advanced remote sensing courses can build; (2) a course dealing with visual image interpretation; (3) a course dealing with quantitative (computer-based) image interpretation; (4) a basic photogrammetry course; and (5) a basic surveying course. These five courses comprise up to one-half of the course work required for the M.S. degree. The nature of other course work and thesis requirements vary greatly, depending on the department in which the degree is being awarded.

Storyboarding as an aid to learning about death in children's nursing.

PubMed

Dexter, Yvonne

2016-06-08

The sudden or anticipated death of a child is one of the most challenging and unique experiences that children's nursing students will encounter in practice. There is evidence to suggest that the effect this can have on a practitioner can affect quality of care. Although education for nurses about dealing with death has been studied, there is limited research into the education of those working with dying children and how effective it is in preparing them to deal with the situation. This deficit presents those involved in children's nurse education with a significant challenge and an opportunity to be innovative. This article examines the use of storyboarding as a creative teaching tool to enable children's nursing students to reflect on their experiences of working with children and families in death situations. The wider implications for the use of this technique in practice and education are considered.

Compassion fatigue and burnout: what managers should know.

PubMed

Slatten, Lise Anne; David Carson, Kerry; Carson, Paula Phillips

2011-01-01

Most health care employees experience and are bolstered by compassion satisfaction as they deal with patients in need. However, the more empathetic a health care provider is, the more likely he or she will experience compassion fatigue. Compassion fatigue is a negative syndrome that occurs when dealing with the traumatic experiences of patients, and examples of symptoms include intrusive thoughts, sleeping problems, and depression. Compassion fatigue is different from burnout. Compassion fatigue is a rapidly occurring disorder for primary health care workers who work with suffering patients, whereas burnout, a larger construct, is a slowly progressing disorder for employees who typically are working in burdensome organizational environments. Managers can mitigate problems associated with compassion fatigue with a number of interventions including patient reassignments, formal mentoring programs, employee training, and a compassionate organizational culture. With burnout, health care managers will want to focus primarily on chronic organizational problems.

This paper deals with an electrical modelling and optimization of a thermal energy harvester dedicated to power autonomous systems. Such devices based on bimetal strips and piezoceramics turn thermal gradients into electricity by a two-step conversion mechanism. This work focuses first on a demonstration of a ST-WSN (GreenNet demonstration platform) supplied by the harvester to validate, for the first time, the harvesters viability. That demonstration focuses attention on the need for an optimized power management circuit for piezoelectric generators able to reach output voltages up to 20 V. The work deals then with the proposal of an equivalent lumped element model of the piezoelectric transducer with its SPICE implementation to enable the optimization of a dedicated power management circuit based on the Pulsed Synchronous Charge Extractor (PSCE). Simulations using the SPICE model and the power management circuit lead to an increased extracted power by 144%.

Diversified Control Paths: A Significant Way Disease Genes Perturb the Human Regulatory Network

2015-01-01

Background The complexity of biological systems motivates us to use the underlying networks to provide deep understanding of disease etiology and the human diseases are viewed as perturbations of dynamic properties of networks. Control theory that deals with dynamic systems has been successfully used to capture systems-level knowledge in large amount of quantitative biological interactions. But from the perspective of system control, the ways by which multiple genetic factors jointly perturb a disease phenotype still remain. Results In this work, we combine tools from control theory and network science to address the diversified control paths in complex networks. Then the ways by which the disease genes perturb biological systems are identified and quantified by the control paths in a human regulatory network. Furthermore, as an application, prioritization of candidate genes is presented by use of control path analysis and gene ontology annotation for definition of similarities. We use leave-one-out cross-validation to evaluate the ability of finding the gene-disease relationship. Results have shown compatible performance with previous sophisticated works, especially in directed systems. Conclusions Our results inspire a deeper understanding of molecular mechanisms that drive pathological processes. Diversified control paths offer a basis for integrated intervention techniques which will ultimately lead to the development of novel therapeutic strategies. PMID:26284649

Voice activity and participation profile presenting coordinates for readjustment of preventive action of educators.

Dragone, Maria Lúcia Suzigan

To investigate the perception of voice impairment in professional and social contexts, to correlate these data with existing data in the literature, and to explore the perception of voice problems and the adherence to vocal health programs. 502 Brazilian educators working in municipal public schools responded to the Voice Activity and Participation Profile (VAPP) questionnaire. Then a correlation was made with previous results in the literature dealing with a dysphonic and a nondysphonic group. The VAPP data showed that self-perception of voice problems had a higher vocal impact on daily communication and lower scores for activity limitation and participation restriction. The educators' scores were closer to those of the nondysphonic group with regard to daily and social communication, and emotional and activity limitation, but perception of the voice problem was closest to that of the dysphonic group. Nevertheless, the opposite was the case for participation restriction. The educators perceive vocal problems but do not perceive participation restriction to the same extent. This may explain the decreasing participation in the Vocal Health Program. It probably occurs because adults voluntarily apply for training when they feel that their work performance needs to improve so that they can carry out their job properly. Copyright © 2010 S.

Only few papers deal with Surface Plasmon Resonance imaging (SPRi) direct detection on complex matrices, limiting the biosensor application to real analytical problems. In this work a SPRi biosensor for anti-bovine IgG detection in untreated human bodily fluids, i.e. diluted human serum and milk, was developed. Enhanced levels of cow's milk antibodies in children's serum are suspected for their possible correlation with Type 1 diabetes during childhood and their detection in real samples was up to now performed by classical immunoassays based on indirect detection. The biosensor was optimised in standard samples and then in untreated human milk for anti-bovine IgG direct detection. The key novelty of the work is the evaluation of matrix effect by applying to real samples an experimental and ex ante method previously developed for SPRi signal sampling in standard solutions, called "Data Analyzer"; it punctually visualises and analyses the behaviour of receptor spots of the array, to select only spot areas with the best specific vs. unspecific signal values. In this way, benefits provide by SPRi image analysis are exploited here to quantify and minimise drawbacks due to the matrix effect, allowing to by-pass every matrix pre-treatment except dilution.

To understand the factors influencing the decisions of rural general practitioners and GP registrars to practise obstetrics, and to understand the impact on these decisions of an innovative obstetric training and support program in the Gippsland region of Victoria. Qualitative approach using semistructured interviews conducted in July and August 2013 and inductive content analysis. Participants were identified from training records over the previous 5 years for the Gippsland GP obstetric training and support program. Two questions were posed during interviews: What challenges face rural GPs in practising obstetrics? What impact has the Gippsland GP obstetric program had on GP obstetric career decisions? Of 60 people invited to participate, 22 agreed. Interviews ranged in duration from 40 to 90 minutes. The major themes that emerged on the challenges facing rural GPs in practising obstetrics were isolation, work-life balance and safety. The major themes that emerged on the impact of the Gippsland GP obstetric program were professional support, structured training and effective leadership. Rural GP obstetricians are challenged by isolation, the impact of their job on work-life balance, and safety. The support, training and leadership offered by the Gippsland expanded obstetric training program helped doctors to deal with these challenges. The Gippsland model of training offers a template for GP obstetric procedural training programs for other rural settings.

Acts of aggression by patients or clients are a part of the average working day for many Health care employees. The objective of the survey was to study the frequency and nature of violence and the handling of aggressive behavior by facility management. The cross-sectional study was conducted in 2017, 81 different healthcare facilities and 1984 employees participated. The questionnaire encompassed socio-demographic details, the frequency of physical violence and verbal abuse, consequences of violence and the stress of employees. In the previous twelve months, 94.1% of the employees in the survey had experienced verbal abuse and 69.8% had experienced physical aggression. Acts of aggression were most commonly encountered in hospitals and residential facilities for the disabled. One third of the employees felt under high levels of stress as a result of the incidents. If the workplace prepares effectively, however, this reduces the perceived stress odds ratio (OR) 0.6, 95% CI 0.4⁻0.8). Violence and aggression are very common. Healthcare facilities are increasingly dealing with this topic. Awareness raising is likely to lead to higher incident reporting rates. Good preparation and an open approach to the topic in the facilities have a positive effect on the feeling of stress and work ability.

In this research, the condition of a road pavement was investigated for the Aborshada Road in the Gharian region of Libya to determine the optimal maintenance works. Previously, a simple engineering judgment was the only procedure followed by the Gharian municipal engineers for evaluating pavements and prioritizing maintenance. The surface condition of the Aborshada Road pavement was investigated using "the Pavement Condition Index (PCI)" visual technique. The pavement was inspected to survey the different distresses in each sample unit. Ninteen pavement distresses were classified according to the PCI standards (PCI for roads and parking lots became an ASTM standard in 2007 (D6433-07)). It was necessary to know the most common distresses of the Aborshada Road to provide assistance for the decision maker in his evaluation of the pavement and the optimum repair method to be selected. This study reveals the actual performance of the pavements and suggests the research required for dealing with the pavement maintenance problem in Libya, especially in the western region. The best maintenance alternative for Aborshada Road was Case No. 3 (Potholes, Long. & Trans. Cracking and Alligator Crack Maintenance). Also, the most common pavement distresses on the Aborshada Road were Distress Nos. 1, 3, 6, 7, 10 and 13 according to the ASTM - D6433-07 classification

Reincentivizing--a new theory of work and work absence.

Work capacity correlates weakly to disease concepts, which in turn are insufficient to explain sick leave behavior. With data mainly from Sweden, a welfare state with high sickness absence rates, our aim was to develop an explanatory theory of how to understand and deal with work absence and sick leave. We used classic grounded theory for analyzing data from >130 interviews with people working or on sick leave, physicians, social security officers, and literature. Several hundreds of typed and handwritten memos were the basis for writing up the theory. In this paper we present a theory of work incentives and how to deal with work absence. We suggest that work disability can be seen as hurt work drivers or people caught in mode traps. Work drivers are specified as work capacities + work incentives, monetary and non-monetary. Also, people can get trapped in certain modes of behavior through changed capacities or incentives, or by inertia. Different modes have different drivers and these can trap the individual from reincentivizing, ie from going back to work or go on working. Hurt drivers and mode traps are recognized by driver assessments done on several different levels. Mode driver calculations are done by the worker. Then follows employer, physician, and social insurance officer assessments. Also, driver assessments are done on the macro level by legislators and other stakeholders. Reincentivizing is done by different repair strategies for hurt work drivers such as body repair, self repair, work-place repair, rehumanizing, controlling sick leave insurance, and strengthening monetary work incentives. Combinations of these driver repair strategies also do release people from mode traps. Reincentivizing is about recognizing hurt work drivers and mode traps followed by repairing and releasing the same drivers and traps. Reincentivizing aims at explaining what is going on when work absence is dealt with and the theory may add to social psychological research on work and work absence, and possibly inform sick leave policies.

Exploring the relationship between black hole accretion and star formation with blind mid-/far-infrared spectroscopic surveys

We present new estimates of redshift-dependent luminosity functions of IR lines detectable by SPICA/SAFARI (SPace InfraRed telescope for Cosmology and Astrophysics/SpicA FAR infrared Instrument) and excited both by star formation and by AGN activity. The new estimates improve over previous work by using updated evolutionary models and dealing in a self-consistent way with emission of galaxies as a whole, including both the starburst and the AGN component. New relationships between line and AGN bolometric luminosity have been derived and those between line and IR luminosities of the starburst component have been updated. These ingredients were used to work out predictions for the source counts in 11 mid-/far-IR emission lines partially or entirely excited by AGN activity. We find that the statistics of the emission line detection of galaxies as a whole is mainly determined by the star formation rate, because of the rarity of bright AGNs. We also find that the slope of the line integral number counts is flatter than two implying that the number of detections at fixed observing time increases more by extending the survey area than by going deeper. We thus propose a wide spectroscopic survey of 1 h integration per field of view over an area of 5 deg2 to detect (at 5σ) ˜760 AGNs in [O IV]25.89 μm - the brightest AGN mid-infrared line - out to z ˜ 2. Pointed observations of strongly lensed or hyperluminous galaxies previously detected by large area surveys such as those by Herschel and by the South Pole Telescope can provide key information on the galaxy-AGN co-evolution out to higher redshifts.

Tactile spatial working memory activates the dorsal extrastriate cortical pathway in congenitally blind individuals.

PubMed

Bonino, D; Ricciardi, E; Sani, L; Gentili, C; Vanello, N; Guazzelli, M; Vecchi, T; Pietrini, P

2008-09-01

In sighted individuals, both the visual and tactile version of the same spatial working memory task elicited neural responses in the dorsal "where" cortical pathway (Ricciardi et al., 2006). Whether the neural response during the tactile working memory task is due to visually-based spatial imagery or rather reflects a more abstract, supramodal organization of the dorsal cortical pathway remains to be determined. To understand the role of visual experience on the functional organization of the dorsal cortical stream, using functional magnetic resonance imaging (fMRI) here we examined brain response in four individuals with congenital or early blindness and no visual recollection, while they performed the same tactile spatial working memory task, a one-back recognition of 2D and 3D matrices. The blind subjects showed a significant activation in bilateral posterior parietal cortex, dorsolateral and inferior prefrontal areas, precuneus, lateral occipital cortex, and cerebellum. Thus, dorsal occipito-parietal areas are involved in mental imagery dealing with spatial components in subjects without prior visual experience and in response to a non-visual task. These data indicate that recruitment of the dorsal cortical pathway in response to the tactile spatial working memory task is not mediated by visually-based imagery and that visual experience is not a prerequisite for the development of a more abstract functional organization of the dorsal stream. These findings, along with previous data indicating a similar supramodal functional organization within the ventral cortical pathway and the motion processing brain regions, may contribute to explain how individuals who are born deprived of sight are able to interact effectively with the surrounding world.

GPs' negotiation strategies regarding sick leave for subjective health complaints.

2015-03-01

To explore general practitioners' (GPs') specific negotiation strategies regarding sick-leave issues with patients suffering from subjective health complaints. Focus-group study. Nine focus-group interviews in three cities in different regions of Norway. 48 GPs (31 men, 17 women; age 32-65), participating in a course dealing with diagnostic practice and assessment of sickness certificates related to patients with subjective health complaints. The GPs identified some specific strategies that they claimed to apply when dealing with the question of sick leave for patients with subjective health complaints. The first step would be to build an alliance with the patient by complying with the wish for sick leave, and at the same time searching for information to acquire the patient's perspective. This position would become the basis for the main goal: motivating the patient for a rapid return to work by pointing out the positive effects of staying at work, making legal and moral arguments, and warning against long-term sick leave. Additional solutions might also be applied, such as involving other stakeholders in this process to provide alternatives to sick leave. GPs seem to have a conscious approach to negotiations of sickness certification, as they report applying specific strategies to limit the duration of sick leave due to subjective health complaints. This give-and-take way of handling sick-leave negotiations has been suggested by others to enhance return to work, and should be further encouraged. However, specific effectiveness of this strategy is yet to be proven, and further investigation into the actual dealings between doctor and patients in these complex encounters is needed.

Feasibility trial of GP and case-managed support for workplace sickness absence.

2014-07-01

Aim Our aim was to compare the return-to-work rates between individuals supported by their GP plus workplace health advisers (intervention group) and those supported by their GP alone. Workplace sickness absence places a significant cost burden on individuals and the wider economy. Previous research shows better outcomes for individuals if they are supported while still in employment, or have been on sick leave for four weeks or less. Those helped back to work at an early stage are more likely to remain at work. A non-medicalised case-managed approach appears to have the best outcomes and can prevent or reduce the slide onto out-of-work benefits, but UK literature on its effectiveness is sparse. The design was a feasibility-controlled trial in which participants were sickness absentees, or presentees in employment with work-related health problems. Individuals completed health status measures (SF-36; EQ-5D) and a Job Content Questionnaire at baseline and again at four-month follow-up. Findings In the intervention group, 29/60 participants completed both phases of the trial. GP practices referred two control patients, and, despite various attempts by the research team, GPs failed to engage with the trial. This finding is of concern, although not unique in primary care research. In earlier studies, GPs reported a lack of knowledge and confidence in dealing with workplace health issues. Despite this, we report interesting findings from the case-managed group, the majority of whom returned to work within a month. Age and length of sickness absence at recruitment were better predictors of return-to-work rates than the number of case-managed contacts. The traditional randomised controlled trial approach was unsuitable for this study. GPs showed low interest in workplace sickness absence, despite their pivotal role in the process. This study informed a larger Department for Work and Pensions study of case-managed support.

2016-01-01

The works of many scholars on Germanic and Slavic Languages do not really try to contrast the two biggest Indo-European language families, but analyse them seperately, as any close comparison seem to be unconvincible. In many works, we find some parts that usually would deal with loan words/borrowings/barbarisms. And, yet, we noticed that there…

Resolving anaphoras for the extraction of drug-drug interactions in pharmacological documents

PubMed Central

2010-01-01

Background Drug-drug interactions are frequently reported in the increasing amount of biomedical literature. Information Extraction (IE) techniques have been devised as a useful instrument to manage this knowledge. Nevertheless, IE at the sentence level has a limited effect because of the frequent references to previous entities in the discourse, a phenomenon known as 'anaphora'. DrugNerAR, a drug anaphora resolution system is presented to address the problem of co-referring expressions in pharmacological literature. This development is part of a larger and innovative study about automatic drug-drug interaction extraction. Methods The system uses a set of linguistic rules drawn by Centering Theory over the analysis provided by a biomedical syntactic parser. Semantic information provided by the Unified Medical Language System (UMLS) is also integrated in order to improve the recognition and the resolution of nominal drug anaphors. Besides, a corpus has been developed in order to analyze the phenomena and evaluate the current approach. Each possible case of anaphoric expression was looked into to determine the most effective way of resolution. Results An F-score of 0.76 in anaphora resolution was achieved, outperforming significantly the baseline by almost 73%. This ad-hoc reference line was developed to check the results as there is no previous work on anaphora resolution in pharmalogical documents. The obtained results resemble those found in related-semantic domains. Conclusions The present approach shows very promising results in the challenge of accounting for anaphoric expressions in pharmacological texts. DrugNerAr obtains similar results to other approaches dealing with anaphora resolution in the biomedical domain, but, unlike these approaches, it focuses on documents reflecting drug interactions. The Centering Theory has proved being effective at the selection of antecedents in anaphora resolution. A key component in the success of this framework is the analysis provided by the MMTx program and the DrugNer system that allows to deal with the complexity of the pharmacological language. It is expected that the positive results of the resolver increases performance of our future drug-drug interaction extraction system. PMID:20406499

Unwed fathers' ability to pay child support: new estimates accounting for multiple-partner fertility.

PubMed

Sinkewicz, Marilyn; Garfinkel, Irwin

2009-05-01

We present new estimates of unwed fathers' ability to pay child support. Prior research relied on surveys that drastically undercounted nonresident unwed fathers and provided no link to their children who lived in separate households. To overcome these limitations, previous research assumed assortative mating and that each mother partnered with one father who was actually eligible to pay support and had no other child support obligations. Because the Fragile Families and Child Wellbeing Study contains data on couples, multiple-partner fertility, and a rich array of other previously unmeasured characteristics of fathers, it is uniquely suited to address the limitations of previous research. We also use an improved method of dealing with missing data. Our findings suggest that previous research overestimated the aggregate ability of unwed nonresident fathers to pay child support by 33% to 60%.

Despite published recommended best practices for full disclosure and apology to patients and families after adverse medical events, actual practice can be inadequate. The use of "cognitive aids" to help practitioners manage complex critical events has been successful in a variety of fields and healthcare. We wished to extend this concept to disclosure and apology events. The aim of this study was to test if a brief opportunity to review a best practice guideline for disclosure and apology would improve communication performance. Thirty pairs of experienced obstetricians and labor nurses participated in a 3-part exercise with mixed-realism simulation. The first part used a standardized actor patient to meet the obstetrical team. The second part used a high-fidelity simulation leading to an adverse medical event (retained sponge), and the third part used standardized actors, patient, and husband, who systematically move through stages of grief response. The participants were randomized into 2 groups, one was provided with a cognitive aid in the form of a best practice guideline for disclosure and apology and the other was only given time to plan. Four blinded raters working in pairs scored subjects on a 7-point scale using a previously developed assessment instrument modified for this study. Pooled ratings of the disclosure and apology discussion for the intervention group (n = 167, mean = 4.9, SD = 0.92) were higher than those from the control group (n = 167, mean = 4.3, SD = 1.21) (P < 0.0001). One specific element was rated higher for the intervention group than the control group; posture toward the patient (n = 27, mean = 5.1, SD = 0.82 versus n = 28, mean = 4.3, SD = 1.33) (P = 0.020). The elements of dealing with anger, dealing with depression, dealing with denial, bargaining, and acceptance were not different. Experienced practitioners performed better in a simulated disclosure and apology conversation after reviewing a cognitive aid in the form of a best practice guideline than a control group that was only given time to prepare.

The determination of the levels of carbohydrates in the yeast Hansenula polymorpha required the development of new analytical procedures. Existing fractionation and analytical methods were adapted to deal with the problems involved with the lysis of whole cells. Using these new procedures, the complete carbohydrate profiles of H. polymorpha and selected mutant strains were determined and shown to correlate favourably with previously published results.
