[Work place health promotion programmes of the statutory German Pension Insurance].

Meffert, C; Mittag, O; Jäckel, W H

2013-12-01

In 2009, the amendment of § 31 Abs. 1 Nr. 2 SGB VI gave the German Pension Insurance the opportunity to provide outpatient medical treatments for insured people who have an occupation with particularly high risk of health. Ever since, the German Pension Insurance has developed various work place prevention programmes, which have been implemented as pilot projects. This article aims at systematically recording and comparatively analyzing these programmes in a synopsis which meets the current state of knowledge. We developed an 8 page questionnaire focusing on work place prevention programmes by the German Pension Insurance. This questionnaire was sent to people in charge of all programmes known to us. All programmes have been drafted -across indications. They are aiming at insured people who already suffer from first health disorders but who are not in imminent need of rehabilitation. However, the concrete target groups at which the specific programmes are aimed differ (shift workers, nurses, elderly employees). Another difference between the various programmes is the setting (in- or outpatients) as well as the duration. All programmes are using existing structures offered by the German Pension Insurance. They provide measures in pension insurance owned rehabilitation centers. It would be desirable to link these performances with internal work place health promotion and offers of other social insurances. © Georg Thieme Verlag KG Stuttgart · New York.

THE GENERAL CONTEXTUAL FRAME FOR PLACING SUPERIOR STUDIES GRADUATES IN THE WORK MARKET

Directory of Open Access Journals (Sweden)

FELICIA ANDRIONI

2013-12-01

Full Text Available Integration in a workplace is an interaction rapport between the individual and the environment. The process of professional integration is strongly linked to the professional aspiration, individual expectations, motivation, and work satisfaction. Placing young graduates of superior studies on the labour market is a challenge for contemporary society. Identifying a suitable work place as well as the certainty of the attained work place are very important elements for young superior studies graduates in the current context of economic crysis. The difficulties in getting a job for superior studies graduates are most frequently associated with lacks in what regards the speciality practical skills and generally, insertion in the work market is achived by getting a position in fields that are related or even different from the speciality field. In an extremely unstable social and economic context, people’s ability to quickly adapt to the requirements of the labour market is fundamental. In this respect, education and professional training have an important role, contributing to the update of knowledge, skills and qualifications of superior studies graduates or future superior studies graduates, eventually allowing them to stay active, flexible, adapted to the situations and requirements of the labour market.

Do work-place initiated measures reduce sickness absence? Preventive measures and sickness absence among older workers in Norway.

Science.gov (United States)

Midtsundstad, Tove I; Nielsen, Roy A

2014-03-01

The article examines whether preventive measures and work adjustments at the establishment level affects sickness absence among workers aged 50 years and older. We combine survey data from a representative sample of 713 Norwegian companies, mapping the prevalence of preventive health measures in the work place in 2005, with register data on sickness absence and demographic variables for workers aged 50 years or older in 2001 and 2007. By means of a difference-in-differences approach, we compare changes and differences in the likelihood of sickness absence among the sample group, with and without the various measures/ instruments in 2005 respectively. In general, work-place preventive measures at the establishment level have not contributed to reducing the probability for sickness absence among workers aged 50 years and older. However, analyses comparing differences between industries find that the work-place measures have had a positive effect on public administration employees. Whether work-place preventive initiatives influence levels of sickness absence seems to be contingent on sector and industry. Therefore, work-place measures may be more effective in the public administration sector where most employees have office jobs compared to sectors such as manufacturing, construction and transportation, where many employees have manual work and more physical demanding jobs. Work-place initiatives thus seem to have less effect on preventing sickness absence in sectors dominated by manual labour.

Current application of work system simulation in participatory ergonomics (PE) design includes a variety of different simulation media. However, the actual influence of the media attributes on the simulation outcome has received less attention. This study investigates two simulation media: full-scale mock-ups and table-top models. The aim is to compare, how the media attributes of fidelity and affordance influence the ergonomics identification and evaluation in PE design of hospital work systems. The results illustrate, how the full-scale mock-ups' high fidelity of room layout and affordance of tool operation support ergonomics identification and evaluation related to the work system entities space and technologies & tools. The table-top models' high fidelity of function relations and affordance of a helicopter view support ergonomics identification and evaluation related to the entity organization. Furthermore, the study addresses the form of the identified and evaluated conditions, being either identified challenges or tangible design criteria.

Chronicity of sexual harassment and generalized work-place abuse: effects on drinking outcomes.

Science.gov (United States)

Rospenda, K M; Richman, J A; Wislar, J S; Flaherty, J A

2000-12-01

This study examined the impact of two forms of interpersonal conflict in the work-place, sexual harassment (SH) and generalized work-place abuse (GWA), on drinking outcomes. We hypothesized that SH and GWA would be associated more strongly with negative outcomes than task-related work stressors, especially when SH and GWA were chronic problems. This was a two-wave panel study. The study was conducted at an urban university in the United States. Participants were 2038 university employees in four occupational groups (faculty, student, clerical and service workers) who responded to both waves of the survey. Data on SH, GWA, task-related stressors and drinking outcomes were gathered from self-report mail questionnaires. Data from 1880 non-abstaining respondents were included in the analyses. SH and GWA experiences were widespread, typically chronic, and tended to co-occur. In regression analyses controlling for demographics, occupational group, prior drinking and task-related stress, GWA chronicity was linked to increased odds of reporting one or more indicators of problem drinking at time 2, in contrast to onset and remission. SH chronicity coupled with no GWA experiences was also significantly related to increased drinking variability. Task-related stressors generally did not explain significant variance in drinking outcomes. SH and GWA may be better predictors of drinking behavior compared to task-related stressors, particularly when harassment is chronic. Increased attention to conflictual relationships in the work-place, the relationship between SH and GWA and the dynamic nature of stressors in general is necessary in future research on drinking behavior.

Participatory simulation in hospital work system design

Andersen, Simone Nyholm

When ergonomic considerations are integrated into the design of work systems, both overall system performance and employee well-being improve. A central part of integrating ergonomics in work system design is to benefit from emplo y-ees’ knowledge of existing work systems. Participatory simulation...... (PS) is a method to access employee knowledge; namely employees are involved in the simulation and design of their own future work systems through the exploration of models representing work system designs. However, only a few studies have investigated PS and the elements of the method. Yet...... understanding the elements is essential when analyzing and planning PS in research and practice. This PhD study investigates PS and the method elements in the context of the Danish hospital sector, where PS is applied in the renewal and design of public hospitals and the work systems within the hospitals...

Full Text Available Background: Dental profession is susceptible to various postural and nonpostural occupational risks. Aim : To determine knowledge, practice, and condition of work place regarding ergonomic posture among dental students from Bhopal city, Central India. Also to observe any correlation among knowledge, practice, and condition of work place scores. Materials and Methods : A self-administered questionnaire study was conducted among 231 dental students. The questionnaire consisted of three parts: Knowledge, practice, and condition of work place. Analysis of variance was used to compare mean of knowledge, practice of clinical posture, and condition of work place. Pearson′s correlation coefficient has been applied to compute correlation among knowledge, practice, and condition of work place scores. A P value < 0.05 was considered significant for all statistical analyses. Results : We found that 70% of dental students perform torsion of the body and cervical flexion to improve vision and prefer direct vision when working. Only 59% reported that they are working with ergonomically designed dental unit and instruments. Most of them reported that the work stool is not comfortable. Mean knowledge, practice, and condition of work place scores were 3.93 (1.26, 5.01 (1.58, and 2.60 (1.14, respectively. Significant differences between the groups were noted for means of practice scores (P ≤ 0.01. Significant linear correlation was seen between knowledge-practice scores (r = 0.20 (P ≤ 0.01, practice-condition of work place scores (r = 0.14 (P ≤ 0.05, and knowledge-condition of work place scores (r = 0.14 (P ≤ 0.05. Conclusion : The knowledge of ergonomic postural requirements and their clinical application among the dental students surveyed were not satisfactory. A multifactorial approach that includes preventive education, postural and positioning strategies, proper selection, and use of ergonomic equipment should be employed.

To examine whether high social capital at work is associated with an increased likelihood of smoking cessation in baseline smokers. Prospective cohort study. Finland. A total of 4853 employees who reported to be smokers in the baseline survey in 2000-2002 (response rate 68%) and responded to a follow-up survey on smoking status in 2004-2005 (response rate 77%). Work-place social capital was assessed using a validated and psychometrically tested eight-item measure. Control variables included sex, age, socio-economic position, marital status, place of work, heavy drinking, physical activity, body mass index and physician-diagnosed depression. In multi-level logistic regression models adjusted for all the covariates, the odds for being a non-smoker at follow-up were 1.26 [95% confidence interval (CI)=1.03-1.55] times higher for baseline smokers who reported high individual-level social capital than for their counterparts with low social capital. In an analysis stratified by socio-economic position, a significant association between individual-level social capital and smoking cessation was observed in the high socio-economic group [odds ratio (OR) (95% CI)=1.63 (1.01-2.63)], but not in intermediate [(OR=1.10 (0.83-1.47)] or low socio-economic groups [(OR=1.28 (0.86-1.91)]. Work unit-level social capital was not associated with smoking cessation. If the observed associations are causal, these findings suggest that high perceived social capital at work may facilitate smoking cessation among smokers in higher-status jobs.

"Should I tell my employer and coworkers I have arthritis?" A longitudinal examination of self-disclosure in the work place.

To examine arthritis self-disclosure at work, factors associated with disclosure, and prospective relationships of self-disclosure and work place support with changes to work place interactions, work transitions, and work place stress. Using a structured questionnaire, participants with osteoarthritis or inflammatory arthritis were interviewed at 4 time points, 18 months apart. At time 1, all participants (n = 490; 381 women, 109 men) were employed. Of the entire sample, 71% were retained throughout the study. Respondents were recruited using community advertising and from rheumatology and rehabilitation clinics. Self-disclosure and perceived support from managers and coworkers was assessed, as well as demographic, illness, work-context, and psychological variables. Generalized estimating equations modeled associations of disclosure and support on changes at work (e.g., job disruptions, work place stress). At each time point, 70.6-76.6% of participants had self-disclosed arthritis to their manager and 85.2-88.1% had told a coworker. Intraindividual variability in disclosure was considerable. Factors associated with self-disclosure were often inconsistent over time, with the exception of variables assessing the need to self-disclose (e.g., activity limitations) and perceived coworker support. Self-disclosure was not associated with changes to work. However, coworker support was related to fewer job disruptions, help with work tasks, and being less likely to reduce hours. Perceived managerial support was associated with less work place stress. Greater awareness is needed about issues related to self-disclosing arthritis at work. This study emphasizes the importance of a supportive work place, especially supportive coworkers, in decisions to discuss arthritis at work and in changes to work that might enable people to remain employed.

Healthcare providers being over-worked and under staffed are prone to poor mental health. Unhealthy work place compounds it further. This study was aimed at to assess the mental health status of a medical university employee with special reference to work place stressors. A cross-sectional study was designed and carried out at a Rural Health University. Both the General Health Questionnaire (GHQ)-12 and Holmes-Rahe Scale were used to evaluate 406 participants. Multivariate analysis, correlation, and ANOVA by SPSS 11.0. The minimum age of the participant was 19 years and the maximum 64 years, with an average age at 35.09 years. On the GHQ scale 239(58.9%) recorded psychiatric morbidity out of which 201(49.5%) had moderate and 38(9.3%) severe morbidity. Doctors were the highest stressed group (P ≤ 0.04). Prominent work environmental stressors were poor departmental reorganization, lack of cohesiveness in department, difficult superiors and juniors (P ≤ 0.001, Pearson correlation). Stressors associated with work organization and work nature were: noninvolvement in departmental decision making and lack of proper feedback; along with; work load, lack of clarity in job, and a erratic work schedule (P ≤ 0.001 on Pearson correlation). Harassment, favoritism, discrimination, and lack of self-expression (P ≤ 0.003) were other factors responsible for work dissatisfaction. A high stress level was detected in the study population. The principal stressors were work environment related. Poor work culture was found to lead to job dissatisfaction among majority.

Four-year follow-up of smoke exposure, attitudes and smoking behaviour following enactment of Finland's national smoke-free work-place law.

2003-08-01

This study evaluated the possible impact of national smoke-free work-place legislation on employee exposure to environmental tobacco smoke (ETS), employee smoking habits and attitudes on work-place smoking regulations. Repeated cross-sectional questionnaire surveys and indoor air nicotine measurements were carried out before, and 1 and 3 years after the law had come into effect. Industrial, service sector and office work-places from the Helsinki metropolitan area, Finland. A total of 880, 940 and 659 employees (response rates 70%, 75% and 75%) in eight work-places selected from a register kept by the Uusimaa Regional Institute of Occupational Health to represent various sectors of public and private work-places. Reported exposure to ETS, smoking habits, attitudes on smoking at work and measurements of indoor air nicotine concentration. Employee exposure to ETS for at least 1 hour daily decreased steadily during the 4-year follow-up, from 51% in 1994 to 17% in 1995 and 12% in 1998. Respondents' daily smoking prevalence and tobacco consumption diminished 1 year after the enforcement of legislation from 30% to 25%, and remained at 25% in the last survey 3 years later. Long-term reduction in smoking was confined to men. Both smokers' and non-smokers' attitudes shifted gradually towards favouring a total ban on smoking at work. Median indoor airborne nicotine concentrations decreased from 0.9 micro g/m3 in 1994-95 to 0.1 micro g/m3 in 1995-96 and 1998. This is the first follow-up study on a nationally implemented smoke-free work-place law. We found that such legislation is associated with steadily reducing ETS exposure at work, particularly at work-places, where the voluntary smoking regulations have failed to reduce exposure. The implementation of the law also seemed to encourage smokers to accept a non-smoking work-place as the norm.

A Multiagent Modeling Environment for Simulating Work Practice in Organizations

Science.gov (United States)

Sierhuis, Maarten; Clancey, William J.; vanHoof, Ron

2004-01-01

In this paper we position Brahms as a tool for simulating organizational processes. Brahms is a modeling and simulation environment for analyzing human work practice, and for using such models to develop intelligent software agents to support the work practice in organizations. Brahms is the result of more than ten years of research at the Institute for Research on Learning (IRL), NYNEX Science & Technology (the former R&D institute of the Baby Bell telephone company in New York, now Verizon), and for the last six years at NASA Ames Research Center, in the Work Systems Design and Evaluation group, part of the Computational Sciences Division (Code IC). Brahms has been used on more than ten modeling and simulation research projects, and recently has been used as a distributed multiagent development environment for developing work practice support tools for human in-situ science exploration on planetary surfaces, in particular a human mission to Mars. Brahms was originally conceived of as a business process modeling and simulation tool that incorporates the social systems of work, by illuminating how formal process flow descriptions relate to people s actual located activities in the workplace. Our research started in the early nineties as a reaction to experiences with work process modeling and simulation . Although an effective tool for convincing management of the potential cost-savings of the newly designed work processes, the modeling and simulation environment was only able to describe work as a normative workflow. However, the social systems, uncovered in work practices studied by the design team played a significant role in how work actually got done-actual lived work. Multi- tasking, informal assistance and circumstantial work interactions could not easily be represented in a tool with a strict workflow modeling paradigm. In response, we began to develop a tool that would have the benefits of work process modeling and simulation, but be distinctively able to

Most chronic illness management occurs outside clinics and hospitals, in the everyday lives of individuals. We use data from semi-structured interviews with 37 veterans from Southeastern Louisiana and Northern California to illustrate how "health work" for mental health concerns are shaped by place. Using health work as an orienting concept for analysis, we discerned variation between the two study sites in how Veterans used interacting with the natural environment, cultivating time alone, and religious practice to manage their mental health and well-being. Through these findings, we advocate for a situated notion of health work that is mindful of how health-related behaviors are shaped by place and the attributes that constitute place.

Richmond, R; Heather, N; Holt, P

1996-12-01

This article presents findings from a survey of programmes available for tobacco and alcohol users working in 455 of Australia's top 600 companies. Companies were twice as likely to have programmes for smokers (43%) as for problem drinkers (24%) and these programmes were more apparent in large companies. The majority of programmes for smoking were delivered within a health promotion context which included other life-style issues, such as nutrition, exercise, weight management and stress management. Although Employee Assistance Programs (EAPs) were the most commonly available type of work-place programme for excessive drinkers and other drug users, followed by Alcoholics Anonymous and local hospital clinics, only 6% had an EAP for alcohol. Only 21% of programmes for smokers and 12% for excessive alcohol users were evaluated. Around one-quarter of companies knew the costs of smoking programmes, and 9% reported costs of conducting programmes for excessive alcohol consumers.

Work System analysis and design is complex and non-deterministic. In this paper we describe Brahms, a multiagent modeling and simulation environment for designing complex interactions in human-machine systems. Brahms was originally conceived as a business process design tool that simulates work practices, including social systems of work. We describe our modeling and simulation method for mission operations work systems design, based on a research case study in which we used Brahms to design mission operations for a proposed discovery mission to the Moon. We then describe the results of an actual method application project-the Brahms Mars Exploration Rover. Space mission operations are similar to operations of traditional organizations; we show that the application of Brahms for space mission operations design is relevant and transferable to other types of business processes in organizations.

Full Text Available This paper is on how auxiliar numeraries, hundreds of women working for the Opus Dei in Mexico, dedicate their efforts and lives to that organization under the promise to get a place in heaven,…and a very small income. They are a vulnerable group, coming from the poor countryside or marginal city’s neighborhoods, and/or with an indigenous community’s background. They are trained to love God through the “charisma”, a set of rules and beliefs that helps them transit a life’s plan to seek their way to heaven. They work confident that following this path they will find salvation, meanwhile they take care of the Opus Dei’s centers, performing activities such as housecleaning. In exchange for their work they earn a salary, that doesn’t go further than their basic needs. Being the organization’s finances something unclear, it is hard to establish whether they could have been used as “cheap labour”. Opus Dei’s executives claim that the organization is deficietary because of all the social work they do; therefore, and that they can only pay a very restricted wage to these women. Based on interviews, fieldwork, bibliography and on-line research, the article shows how that claim may not be correct, and that some kind of rights violations are behind the relationship between the Opus Dei - auxiliar numeraries.

Full Text Available ABSTRACT: This study aimed to develop and validate an ergonomics index for the operator workplace assessment of agricultural tractors sold in the Brazilian market. To develop the ergonomics index, the operator work places were assessed for compliance with current, national and international, safety and ergonomics standards. The following standards were analyzed to develop ergonomics index: ISO 15077 (1996, which regulates the position of operator controls; ABNT NBR ISO 4254-1(2015 and ABNT NBR ISO 4252 (2011, which regulate the access to operator workplaces; and NR 12 (2010, which determines the mandatory items of operator workplaces.Thirty-four operator work places of 152 models of new agricultural tractors sold in the Brazilian market were analyzed in this study. Ergonomics index was developed and validated using these standards, and the findings enabled the ranking of agricultural tractors. Therefore, the proposed ergonomics index proved feasible and may be applied to other agricultural machines.

The analysis of the relationship between stress at work and results of cognitive functions amongst women, at peri- and post-menopausal age, performing intellectual work. The study group included women, aged 45-66 years old, employed as intellectual workers. Research instruments were: the Montreal Cognitive Assessment; computer tests of the CNS Vital Signs; the Subjective Work Characteristics Questionnaire, and a questionnaire designed by the author. The results were statistically analyzed. Nearly a half of respondents experienced high stress at the place of work; 1/3 - on the average level, on a low level - every fifth. The largest number of respondents experienced stress caused by social contacts. Among a half of the women, stress was caused by the lack of awards at work, followed by the lack of support. Slightly fewer of them experienced stress caused by the feeling of psychological load related to the complexity of work or the feeling of uncertainty caused by the organization of work. Every third woman experienced stress due to the sense of responsibility or the lack of control. The smallest number experienced stress caused by physical arduousness, the sense of threat and unpleasant working conditions. The examined women obtained the best results with respect to simple attention, the worst results - with respect to the reaction time. The results concerning the remaining 9 cognitive functions were ranked in the middle of the aforementioned results. The intensity of stress at work and factors which caused this stress, negatively correlated with simple attention of women in the early peri-menopausal period, while positively correlating with the psychomotor and processing speed of women in the late peri-menopausal period. Among the post-menopausal women, negative correlations were observed between the majority of cognitive functions and the intensity of stress at work, and the majority of factors which caused this stress. Cognitive functions of the examined women

Portrat, Sophie; Guida, Alessandro; Phénix, Thierry; Lemaire, Benoît

Working memory (WM) is a cognitive system allowing short-term maintenance and processing of information. Maintaining information in WM consists, classically, in rehearsing or refreshing it. Chunking could also be considered as a maintenance mechanism. However, in the literature, it is more often used to explain performance than explicitly investigated within WM paradigms. Hence, the aim of the present paper was (1) to strengthen the experimental dialogue between WM and chunking, by studying the effect of acronyms in a computer-paced complex span task paradigm and (2) to formalize explicitly this dialogue within a computational model. Young adults performed a WM complex span task in which they had to maintain series of 7 letters for further recall while performing a concurrent location judgment task. The series to be remembered were either random strings of letters or strings containing a 3-letter acronym that appeared in position 1, 3, or 5 in the series. Together, the data and simulations provide a better understanding of the maintenance mechanisms taking place in WM and its interplay with long-term memory. Indeed, the behavioral WM performance lends evidence to the functional characteristics of chunking that seems to be, especially in a WM complex span task, an attentional time-based mechanism that certainly enhances WM performance but also competes with other processes at hand in WM. Computational simulations support and delineate such a conception by showing that searching for a chunk in long-term memory involves attentionally demanding subprocesses that essentially take place during the encoding phases of the task.

Dynamic characteristics between waves and a floating cylindrical body connected to a tension-leg mooring cable placed in a simulated offshore environment

Full Text Available Given the rapid progress made in understanding the dynamics of an offshore floating body in an ocean environment, the present study aimed to simulate ocean waves in a small-sized wave flume and to observe the motion of a cylindrical floating body placed in an offshore environment. To generate regular ocean waves in a wave flume, we combined a wave generator and a wave absorber. In addition, to precisely visualise the oscillation of the body, a set of light-emitting diode illuminators and a high-speed charge-coupled device camera were installed in the flume. This study also focuses on the spectral analysis of the movement of the floating body. The wave generator and absorbers worked well to simulate stable regular waves. In addition, the simulated waves agreed well with the plane waves predicted by shallow-water theory. As the period of the oncoming waves changed, the movement of the floating body was substantially different when tethered to a tension-leg mooring cable. In particular, when connected to the tension-leg mooring cable, the natural frequency of the floating body appeared suddenly at 0.391 Hz as the wave period increased.

The delayed-matching-to-place (DMP) dry maze test is a variant of DMP water maze (Steele and Morris, 1999; Faizi et al. , 2012) which measures spatial working/episodic-like learning and memory that depends on both hippocampal and cortical functions (Wang and Morris, 2010; Euston et al. , 2012). Using this test we can detect normal aging related spatial working memory decline, as well as trauma induced working memory deficits. Furthermore, we recently reported that fractionated whole brain irradiation does not affect working memory in mice (Feng et al. , 2016). Here we describe the experimental setup and procedures of this behavioral test.

To examine the type, degree, and episodic nature of arthritis-related work place activity limitations and the consistency of the relationship of activity limitations to job modifications and work place outcomes. Using an interviewer-administered structured questionnaire, individuals with osteoarthritis (OA) or inflammatory arthritis (IA) were interviewed at 4 time points, 18 months apart. At baseline, all participants (n = 490; 381 women, 109 men) were employed. Respondents were recruited using community advertising and from rheumatology and rehabilitation clinics. The Workplace Activity Limitations Scale (WALS) assessed arthritis-related disability with job tasks. Job modifications/accommodations (e.g., scheduling changes), work place outcomes (e.g., absenteeism), demographics, illness, and work context were also measured. Repeated cross-sectional logistic regressions examined levels of WALS disability with job modifications and outcomes at each time point. Similar levels of activity limitations were found comparing OA and IA with fewer difficulties with global aspects of work (e.g., scheduling) than with specific tasks (e.g., working with hands). Three-quarters of the participants had episodic or intermittent WALS difficulty over time. Medium and high levels of work place activity limitations were significantly associated with job modifications, and high WALS difficulty was consistently related to negative work outcomes. Many individuals with arthritis report some difficulty with work place activities. However, these difficulties are often intermittent and may not result in changes to work productivity until they are consistently high. This is important for designing work place interventions and for employers, insurers, and the government to understand to avoid viewing individuals with arthritis as a permanent drain on work place and health resources.

Full Text Available In the present paper there is presented how to achieve a load equilibration of workstations for a conveyor with imposed pace, in the case of manufacturing uppers for a women boots model. Equilibration of work charging is done by switching worker’s operations in order to use at full time each worker placed in the technological flow process. In the manufacruring process of shoe uppers of the considered model, there have been established the operative time and production rates per operation. Thus there has been calculated the work necessary amount Nci for accomplishing different production rates: Q=600,650, 700, 750... 900pairs/ 8 h and the necessary amount of work Nai was adopted. A technology line of manufacturing a footwear item is used at its optimum capacity when the number of work vacancy is minimum, 0.013 corresponding to a flow production of 700pairs / 8h the highest labor productivity being obtained, ie 17.5 pairs / worker • 8h. By equilibrating the work charge for each operation, it is obtained, for a daily production of 700pairs / 8h, a reduction of the number of workspaces from 40 to 36 workers and hence a labor productivity of 19.44 pairs / worker • 8h.

Multiagent Work Practice Simulation: Progress and Challenges

Science.gov (United States)

Clancey, William J.; Sierhuis, Maarten

2002-01-01

Modeling and simulating complex human-system interactions requires going beyond formal procedures and information flows to analyze how people interact with each other. Such work practices include conversations, modes of communication, informal assistance, impromptu meetings, workarounds, and so on. To make these social processes visible, we have developed a multiagent simulation tool, called Brahms, for modeling the activities of people belonging to multiple groups, situated in a physical environment (geographic regions, buildings, transport vehicles, etc.) consisting of tools, documents, and computer systems. We are finding many useful applications of Brahms for system requirements analysis, instruction, implementing software agents, and as a workbench for relating cognitive and social theories of human behavior. Many challenges remain for representing work practices, including modeling: memory over multiple days, scheduled activities combining physical objects, groups, and locations on a timeline (such as a Space Shuttle mission), habitat vehicles with trajectories (such as the Shuttle), agent movement in 3d space (e.g., inside the International Space Station), agent posture and line of sight, coupled movements (such as carrying objects), and learning (mimicry, forming habits, detecting repetition, etc.).

Safe places for pedestrians: using cognitive work analysis to consider the relationships between the engineering and urban design of footpaths.

Science.gov (United States)

Stevens, Nicholas; Salmon, Paul

2014-11-01

Footpaths provide an integral component of our urban environments and have the potential to act as safe places for people and the focus for community life. Despite this, the approach to designing footpaths that are safe while providing this sense of place often occurs in silos. There is often very little consideration given to how designing for sense of place impacts safety and vice versa. The aim of this study was to use a systems analysis and design framework to develop a design template for an 'ideal' footpath system that embodies both safety and sense of place. This was achieved through using the first phase of the Cognitive Work Analysis framework, Work Domain Analysis, to specify a model of footpaths as safe places for pedestrians. This model was subsequently used to assess two existing footpath environments to determine the extent to which they meet the design requirements specified. The findings show instances where the existing footpaths both meet and fail to meet the design requirements specified. Through utilising a systems approach for footpaths, this paper has provided a novel design template that can inform new footpath design efforts or be used to evaluate the extent to which existing footpaths achieve their safety and sense of place requirements.

A working group on detector simulation was formed as part of the high-energy physics (HEP) Software Foundation's initiative to prepare a Community White Paper that describes the main software challenges and opportunities to be faced in the HEP field over the next decade. The working group met over a period of several months in order to review the current status of the Full and Fast simulation applications of HEP experiments and the improvements that will need to be made in order to meet the goals of future HEP experimental programmes. The scope of the topics covered includes the main components of a HEP simulation application, such as MC truth handling, geometry modeling, particle propagation in materials and fields, physics modeling of the interactions of particles with matter, the treatment of pileup and other backgrounds, as well as signal processing and digitisation. The resulting work programme described in this document focuses on the need to improve both the software performance and the physics of detector simulation. The goals are to increase the accuracy of the physics models and expand their applicability to future physics programmes, while achieving large factors in computing performance gains consistent with projections on available computing resources.

Full Text Available Drawing on French anthropologist Marc Augé and his seminal book Non-Places (1995 the author pays attention to the transformation of contemporary urban landscapes. In thinking trough the dialectic of place and non-place, this paper aims to account for the apparent sense of placelesness in our cultural landscapes and in increasingly globalised world. If we want to ask fundamental questions about what has happened to our urban landscape and to the spirit of cities during the last decades then the concepts of place and non-place help us to describe the actual changes. Besides, Augé’s work gives us the methodological tools to address philosophical questions about the nature of supermodernity and the relationship between modernity and postmodernity moving toward new conditions of globality. This article will attempt to apply anthropological and philosophical concepts of place and space to the context of Lithuania, comparing the ways of spreading of non-places (non-lieu in the Soviet modernity and contemporary global, hyper-visual and liquid cultural landscape.

We examined how efferent projections from VTA to HPC influence spatial working memory and place fields when the reward context changes. CA1 and CA3 process environmental context changes differently and VTA preferentially innervates CA1. Given these anatomical data and electrophysiological evidence that implicate DA in reward processing, we predicted that CA1 place fields would respond more strongly to both VTA disruption and changes in the reward context than CA3 place fields. Rats (N = 9) were implanted with infusion cannula targeting VTA and recording tetrodes aimed at HPC. Then they were tested on a differential reward, win-shift working memory task. One recording session consisted of 5 baseline and 5 manipulation trials during which place cells in CA1/CA2 (N = 167) and CA3 (N = 94) were recorded. Prior to manipulation trials rats were infused with either baclofen or saline and then subjected to control or reward conditions during which the learned locations of large and small reward quantities were reversed. VTA disruption resulted in an increase in errors, and in CA1/CA2 place field reorganization. There were no changes in any measures of CA3 place field stability during VTA disruption. Reward manipulations did not affect performance or place field stability in CA1/CA2 or CA3; however, changes in the reward locations "rescued" performance and place field stability in CA1/CA2 when VTA activity was compromised, perhaps by trigging compensatory mechanisms. These data support the hypothesis that VTA contributes to spatial working memory performance perhaps by maintaining place field stability selectively in CA1/CA2. Copyright © 2009 Wiley-Liss, Inc.

2018-01-01

Waste management planning is an interdisciplinary task covering a wide range of issues including costs, legal requirements, spatial planning, environmental protection, geography, demographics, and techniques used in collecting, transporting, processing and disposing of waste. Designing and analyzing this issue is difficult and requires the use of advanced analysis methods and tools available in GIS geographic information systems containing readily available graphical and descriptive databases, data analysis tools providing expert decision support while selecting the best-designed alternative, and simulation models that allow the user to simulate many variants of waste management together with graphical visualization of the results of performed analyzes. As part of the research study, there have been works undertaken concerning the use of multi-criteria data analysis in waste management in areas located in southwestern Poland. These works have proposed the inclusion in waste management of post-mining excavations as places for the final or temporary collection of waste assessed in terms of their suitability with the tools available in GIS systems.

1990-01-01

In the present paper the design of a part-task simulator for WWER-440 type nuclear power plant units by the CEZ (Czech Power Works) Concern is reported. This part-task simulator has been designed for the training of NPP operating personnel. It includes a central computer that is coupled with the training work places and the trainer place. Interchange of information is performed by functional keyboards and semigraphical colour displays. The process is simulated, also in real time scale, on the basis of dynamic models. In addition to the precision of the models used, great importance has primarily been attached to plasticity of information presentation. The part-task simulator may be applied to simulation and demonstration as well as to teaching purposes. The paper presents the achieved state of implementation of the part-task simulator and points out some further stage of evolution. (author)

Ishii, Hirotake; Man, Zhiyuan; Yan, Weida; Shimoda, Hiroshi; Izumi, Masanori

2015-01-01

An augmented reality-based simulation system for cooperative plant dismantling work has been developed and evaluated. In the system, behaviors of virtual objects such as the dismantling target, chain blocks, and trolleys are physically simulated. Their appearance is superimposed on camera images captured with cameras on users' tablet devices. The users can manipulate virtual objects cooperatively via touch operation. They can cut the dismantling targets, lift them on the trolleys using chain blocks, and convey them through narrow passages to ascertain whether the dismantling targets can be conducted without colliding with the passages. During the simulation, collisions between the virtual objects and real work environment are detected based on their three-dimensional shape data measured in advance. The collided parts are visualized using augmented reality superimposition. Four evaluators assessed the simulation system. Results show that the simulation system can be useful for prior examination of dismantling works, but some points were also found to need improvement. (author)

Remote collaboration system based on large scale simulation

International Nuclear Information System (INIS)

Kishimoto, Yasuaki; Sugahara, Akihiro; Li, J.Q.

2008-01-01

Large scale simulation using super-computer, which generally requires long CPU time and produces large amount of data, has been extensively studied as a third pillar in various advanced science fields in parallel to theory and experiment. Such a simulation is expected to lead new scientific discoveries through elucidation of various complex phenomena, which are hardly identified only by conventional theoretical and experimental approaches. In order to assist such large simulation studies for which many collaborators working at geographically different places participate and contribute, we have developed a unique remote collaboration system, referred to as SIMON (simulation monitoring system), which is based on client-server system control introducing an idea of up-date processing, contrary to that of widely used post-processing. As a key ingredient, we have developed a trigger method, which transmits various requests for the up-date processing from the simulation (client) running on a super-computer to a workstation (server). Namely, the simulation running on a super-computer actively controls the timing of up-date processing. The server that has received the requests from the ongoing simulation such as data transfer, data analyses, and visualizations, etc. starts operations according to the requests during the simulation. The server makes the latest results available to web browsers, so that the collaborators can monitor the results at any place and time in the world. By applying the system to a specific simulation project of laser-matter interaction, we have confirmed that the system works well and plays an important role as a collaboration platform on which many collaborators work with one another

Full Text Available Introduction and Objective: Employment is indispensible for humans. There is a two-way interaction between the employee’s health and his working environment. Health affects working life and working life, too, affects health. Our study has been carried out in a descriptive manner, in order to determine the workplace conditions, satisfaction rates and training needs of workers at a textile factory in the Southeastern Region of Turkey, Material and Method: This study was carried out at a textile factory in the Southeastern Region of Turkey, on 200 workers who were willing to fill out a questionnaire form, between 1st March 2009 and 30th April 2009. Data were gathered by vis-a-vis meeting with workers, using a questionnaire form devised by researchers rewieving related literature.

Reprint of "Safe places for pedestrians: using cognitive work analysis to consider the relationships between the engineering and urban design of footpaths".

Science.gov (United States)

Stevens, Nicholas; Salmon, Paul

2015-01-01

Footpaths provide an integral component of our urban environments and have the potential to act as safe places for people and the focus for community life. Despite this, the approach to designing footpaths that are safe while providing this sense of place often occurs in silos. There is often very little consideration given to how designing for sense of place impacts safety and vice versa. The aim of this study was to use a systems analysis and design framework to develop a design template for an 'ideal' footpath system that embodies both safety and sense of place. This was achieved through using the first phase of the Cognitive Work Analysis framework, Work Domain Analysis, to specify a model of footpaths as safe places for pedestrians. This model was subsequently used to assess two existing footpath environments to determine the extent to which they meet the design requirements specified. The findings show instances where the existing footpaths both meet and fail to meet the design requirements specified. Through utilising a systems approach for footpaths, this paper has provided a novel design template that can inform new footpath design efforts or be used to evaluate the extent to which existing footpaths achieve their safety and sense of place requirements.

Molecular simulation studies on thermophysical properties with application to working fluids

CERN Document Server

Raabe, Gabriele

2017-01-01

This book discusses the fundamentals of molecular simulation, starting with the basics of statistical mechanics and providing introductions to Monte Carlo and molecular dynamics simulation techniques. It also offers an overview of force-field models for molecular simulations and their parameterization, with a discussion of specific aspects. The book then summarizes the available know-how for analyzing molecular simulation outputs to derive information on thermophysical and structural properties. Both the force-field modeling and the analysis of simulation outputs are illustrated by various examples. Simulation studies on recently introduced HFO compounds as working fluids for different technical applications demonstrate the value of molecular simulations in providing predictions for poorly understood compounds and gaining a molecular-level understanding of their properties. This book will prove a valuable resource to researchers and students alike.

The aim of this study was to investigate the effects of 4 consecutive simulated night shifts on glucose homeostasis, mitochondrial function and central and peripheral rhythmicities compared with a simulated day shift schedule. Seventeen healthy adults (8M:9F) matched for sleep, physical activity and dietary/fat intake participated in this study (night shift work n = 9; day shift work n = 8). Glucose tolerance and insulin sensitivity before and after 4 nights of shift work were measured by an intravenous glucose tolerance test and a hyperinsulinaemic euglycaemic clamp respectively. Muscles biopsies were obtained to determine insulin signalling and mitochondrial function. Central and peripheral rhythmicities were assessed by measuring salivary melatonin and expression of circadian genes from hair samples respectively. Fasting plasma glucose increased (4.4 ± 0.1 vs. 4.6 ± 0.1 mmol L -1 ; P = .001) and insulin sensitivity decreased (25 ± 7%, P night shift, with no changes following the day shift. Night shift work had no effect on skeletal muscle protein expression (PGC1α, UCP3, TFAM and mitochondria Complex II-V) or insulin-stimulated pAkt Ser473, pTBC1D4Ser318 and pTBC1D4Thr642. Importantly, the metabolic changes after simulated night shifts occurred despite no changes in the timing of melatonin rhythmicity or hair follicle cell clock gene expression across the wake period (Per3, Per1, Nr1d1 and Nr1d2). Only 4 days of simulated night shift work in healthy adults is sufficient to reduce insulin sensitivity which would be expected to increase the risk of T2D. © 2018 Scandinavian Physiological Society.

A framework of knowledge creation processes in participatory simulation of hospital work systems.

Science.gov (United States)

Andersen, Simone Nyholm; Broberg, Ole

2017-04-01

Participatory simulation (PS) is a method to involve workers in simulating and designing their own future work system. Existing PS studies have focused on analysing the outcome, and minimal attention has been devoted to the process of creating this outcome. In order to study this process, we suggest applying a knowledge creation perspective. The aim of this study was to develop a framework describing the process of how ergonomics knowledge is created in PS. Video recordings from three projects applying PS of hospital work systems constituted the foundation of process mining analysis. The analysis resulted in a framework revealing the sources of ergonomics knowledge creation as sequential relationships between the activities of simulation participants sharing work experiences; experimenting with scenarios; and reflecting on ergonomics consequences. We argue that this framework reveals the hidden steps of PS that are essential when planning and facilitating PS that aims at designing work systems. Practitioner Summary: When facilitating participatory simulation (PS) in work system design, achieving an understanding of the PS process is essential. By applying a knowledge creation perspective and process mining, we investigated the knowledge-creating activities constituting the PS process. The analysis resulted in a framework of the knowledge-creating process in PS.

Workability and Requests for Flexible Work Arrangements Among Older Adults: The Role of a Time and Place Management Intervention.

Morelock, Jeremiah C; McNamara, Tay K; James, Jacquelyn B

2017-11-01

This article investigates the effect of an intervention on the workability of older adults (i.e., the competence, health, and other mental and physical characteristics that workers need to meet the demands of their jobs). We used data from health care workers ( N = 437) who participated in a "time and place management" (TPM) intervention. Although related to flexible work options that aim to give workers more choice and control over the time and place of their work, TPM is conceptually distinct in that it focuses on the processes and guidelines necessary to the successful management of choice and control rather than the options alone. We focused on how the TPM intervention moderated the relationship between age and workability over time, with a particular focus on variation by baseline workability. Our results indicated that the intervention can benefit older workers with low workability.

2002-10-01

Full Text Available The paper presents the approach of developing simulation models of stevedoring work in oil terminal using aggregate approach and simulation system ARENA. Aggregate approach permits to develop formal specification of simulated systems. Aggregate specification of the system is presented as a set of interacting piece-linear aggregates. Controlling sequences are used for formal description of each piece-linear aggregate. Transformation of aggregate formal specification to ARENA system operators permits to develop a simulation model. The developed model permits to evaluate characteristics of the Klaipėda oil terminal which are used both in queuing theory and analysing timing properties of real-time systems.

Progressive decrease of melatonin production over consecutive days of simulated night work.

Science.gov (United States)

Dumont, Marie; Paquet, Jean

2014-12-01

Decreased melatonin production, due to nighttime exposure to light, has been proposed as one of the physiological mechanisms increasing cancer risk in night workers. However, few studies measured melatonin production in night workers, and most of these studies did not measure melatonin over 24 h. One study compared total melatonin production between day and night shifts in rotating night workers and did not find significant differences. However, without baseline measures, it was not possible to exclude that melatonin production was reduced during both day and night work. Here, we used data collected in a simulation study of night work to determine the effect of night work on both nighttime and 24-h melatonin production, during three consecutive days of simulated night work. Thirty-eight healthy subjects (15 men, 23 women; 26.6 ± 4.2 years) participated in a 6-d laboratory study. Circadian phase assessments were made with salivary dim light melatonin onset (DLMO) on the first and last days. Simulated day work (09:00-17:00 h) occurred on the second day, followed by three consecutive days of simulated night work (00:00-08:00 h). Light intensity at eye level was set at 50 lux during both simulated day and night work. The subjects were divided into three matched groups exposed to specific daytime light profiles that produced various degrees of circadian phase delays and phase advances. Melatonin production was estimated with the excretion of urinary 6-sulfatoxymelatonin (aMT6s). For the entire protocol, urine was collected every 2 h, except for the sleep episodes when the interval was 8 h. The aMT6s concentration in each sample was multiplied by the urine volume and then added to obtain total aMT6s excretion during nighttime (00:00-08:00 h) and during each 24-h day (00:00-00:00 h). The results showed that melatonin production progressively decreased over consecutive days of simulated night work, both during nighttime and over the 24 h. This

Humans running in place on water at simulated reduced gravity.

Directory of Open Access Journals (Sweden)

Alberto E Minetti

Full Text Available BACKGROUND: On Earth only a few legged species, such as water strider insects, some aquatic birds and lizards, can run on water. For most other species, including humans, this is precluded by body size and proportions, lack of appropriate appendages, and limited muscle power. However, if gravity is reduced to less than Earth's gravity, running on water should require less muscle power. Here we use a hydrodynamic model to predict the gravity levels at which humans should be able to run on water. We test these predictions in the laboratory using a reduced gravity simulator. METHODOLOGY/PRINCIPAL FINDINGS: We adapted a model equation, previously used by Glasheen and McMahon to explain the dynamics of Basilisk lizard, to predict the body mass, stride frequency and gravity necessary for a person to run on water. Progressive body-weight unloading of a person running in place on a wading pool confirmed the theoretical predictions that a person could run on water, at lunar (or lower gravity levels using relatively small rigid fins. Three-dimensional motion capture of reflective markers on major joint centers showed that humans, similarly to the Basilisk Lizard and to the Western Grebe, keep the head-trunk segment at a nearly constant height, despite the high stride frequency and the intensive locomotor effort. Trunk stabilization at a nearly constant height differentiates running on water from other, more usual human gaits. CONCLUSIONS/SIGNIFICANCE: The results showed that a hydrodynamic model of lizards running on water can also be applied to humans, despite the enormous difference in body size and morphology.

Wu, Guangdong; Duan, Kaifeng; Zuo, Jian; Yang, Jianlin; Wen, Shiping

2016-01-01

The construction industry is a demanding work environment where employees’ work-family conflict is particularly prominent. This conflict has a significant impact on job and family satisfaction and performance of employees. In order to analyze the dynamic evolution of construction industry employee’s work-family conflict between work and family domains, this paper constructs a bi-directional dynamic model framework of work-family conflict by referring to the relevant literature. Consequently, a system dynamics model of employee’s work-family conflict in the construction industry is established, and a simulation is conducted. The simulation results indicate that construction industry employees experience work interference with family conflict (WIFC) levels which are significantly greater than the family interference with work conflict (FIWC) levels. This study also revealed that improving work flexibility and organizational support can have a positive impact on the satisfaction and performance of construction industry employees from a work and family perspective. Furthermore, improving family support can only significantly improve employee job satisfaction. PMID:27801857

In order to analyze the dynamic evolution of construction industry employee's work-family conflict between work and family domains, this paper constructs a bi-directional dynamic model framework of work-family conflict by referring to the relevant literature. Consequently, a system dynamics model of employee's work-family conflict in the construction industry is established, and a simulation is conducted. The simulation results indicate that construction industry employees experience work interference with family conflict (WIFC) levels which are significantly greater than the family interference with work conflict (FIWC) levels. This study also revealed that improving work flexibility and organizational support can have a positive impact on the satisfaction and performance of construction industry employees from a work and family perspective. Furthermore, improving family support can only significantly improve employee job satisfaction.

To Place or Not to Place: Toward an Environmental History of Modern Medicine.

Science.gov (United States)

Sellers, Christopher

2018-01-01

Reviewing recent, overlapping work by historians of medicine and health and of environmental history, this article proposes a further agenda upon which scholars in both fields may converge. Both environmental and medical historians can seek to understand the past two centuries of medical history in terms of a seesaw dialogue over the ways and means by which physicians and other health professionals did, and did not, consider the influence of place-airs and waters included-on disease. Modernizing and professionalizing as well as new styles of science nourished attendant aspirations for a clinical place neutrality, for a medicine in which patients' own places didn't matter to what doctors thought or did. The rise of place neutrality from the late nineteenth century onward also had close and enabling historical ties to the near-simultaneous formation of place-defined specialties-tropical medicine, bacteriological public health, and industrial medicine and hygiene.

1997-01-01

This paper describes the methodology and results of a network simulation study of the Dual Arm Work Package (DAWP), to be employed for dismantling the Argonne National Laboratory CP-5 reactor. The development of the simulation model was based upon the results of a task analysis for the same system. This study was performed by the Oak Ridge National Laboratory (ORNL), in the Robotics and Process Systems Division. Funding was provided the US Department of Energy's Office of Technology Development, Robotics Technology Development Program (RTDP). The RTDP is developing methods of computer simulation to estimate telerobotic system performance. Data were collected to provide point estimates to be used in a task network simulation model. Three skilled operators performed six repetitions of a pipe cutting task representative of typical teleoperation cutting operations

Kevin R. Schwartz

2015-12-01

Full Text Available Introduction: Increasingly, pediatric and emergency medicine (EM residents are pursuing clinical rotations in low-income countries. Optimal pre-departure preparation for such rotations has not yet been established. High-fidelity simulation represents a potentially effective modality for such preparation. This study was designed to assess whether a pre-departure high-fidelity medical simulation curriculum is effective in helping to prepare residents for clinical rotations in a low-income country. Methods: 43 pediatric and EM residents planning clinical rotations in Liberia, West Africa, participated in a simulation-based curriculum focused on severe pediatric malaria and malnutrition and were then assessed by survey at three time points: pre-simulation, post-simulation, and after returning from work abroad. Results: Prior to simulation, 1/43 (2% participants reported they were comfortable with the diagnosis and management of severe malnutrition; this increased to 30/42 (71% after simulation and 24/31 (77% after working abroad. Prior to simulation, 1/43 (2% of residents reported comfort with the diagnosis and management of severe malaria; this increased to 26/42 (62% after simulation and 28/31 (90% after working abroad; 36/42 (86% of residents agreed that a simulation-based global health curriculum is more useful than a didactic curriculum alone, and 41/42 (98% felt a simulator-based curriculum should be offered to all residents planning a clinical trip to a low-income country. Conclusion: High-fidelity simulation is effective in increasing residents’ self-rated comfort in management of pediatric malaria and malnutrition and a majority of participating residents feel it should be included as a component of pre-departure training for all residents rotating clinically to low-income countries.

Place in Pacific Islands Climate Education

Barros, C.; Koh, M. W.

2015-12-01

Understanding place, including both the environment and its people, is essential to understanding our climate, climate change, and its impacts. For us to develop a sense of our place, we need to engage in multiple ways of learning: observation, experimentation, and opportunities to apply new knowledge (Orr, 1992). This approach allows us to access different sources of knowledge and then create local solutions for local issues. It is especially powerful when we rely on experts and elders in our own community along with information from the global community.The Pacific islands Climate Education Partnership (PCEP) is a collaboration of partners—school systems, nongovernmental organizations, and government agencies—working to support learning and teaching about climate in the Pacific. Since 2009, PCEP partners have been working together to develop and implement classroom resources, curriculum standards, and teacher professional learning opportunities in which learners approach climate change and its impacts first through the lens of their own place. Such an approach to putting place central to teaching and learning about climate requires partnership and opportunities for learners to explore solutions for and with their communities. In this presentation, we will share the work unfolding in the Republic of the Marshall Islands (RMI) as one example of PCEP's approach to place-based climate education. Three weeklong K-12 teacher professional learning workshops took place during June-July 2015 in Majuro, RMI on learning gardens, climate science, and project-based learning. Each workshop was co-taught with local partners and supports educators in teaching climate-related curriculum standards through tasks that can foster sense of place through observation, experimentation, and application of new knowledge. Additionally, we will also share PCEP's next steps in place-based climate education, specifically around emerging conversations about the importance of highlighting

The Baltimore Therapeutic Equipment (BTE) work simulator is routinely used by occupational therapists in functional capacity evaluation. Currently, there is a lack of normative data for various attachments on this instrument. The purposes of this study were to (a) establish norms for the biomechanical and physiological responses during three tasks on the BTE work simulator, namely, wheel-turn, push-pull, and overhead-reach; (b) compare these responses during the three tasks, and (c) examine the interrelationships of these responses during the tasks. Twenty healthy men completed five testing sessions: (a) task familiarization on the BTE work simulator to identify the work intensity, which was perceived as hard on the Borg scale; (b) an incremental arm ergometer exercise test to determine their peak oxygen uptake (pVO2) and peak heart rate (pHR); and (c) one of the three tasks on the BTE work simulator for 4 min in each of the next three sessions. Analysis of variance indicated that torque, work, and power during the overhead-reach were significantly higher (p = .000) compared with the wheel-turn and push-pull tasks. However, no significant differences (p > .05) were observed among the tasks for the VO2 and HR, which were approximately 50% and 70% of pVO2 and pHR respectively. Although there was a significant relationship (p batteries, and that there is no consistent relationship between cardiorespiratory fitness and performance of various tasks on the BTE work simulator.

The effects of fatigue on performance in simulated nursing work.

Science.gov (United States)

Barker, Linsey M; Nussbaum, Maury A

2011-09-01

Fatigue is associated with increased rates of medical errors and healthcare worker injuries, yet existing research in this sector has not considered multiple dimensions of fatigue simultaneously. This study evaluated hypothesised causal relationships between mental and physical fatigue and performance. High and low levels of mental and physical fatigue were induced in 16 participants during simulated nursing work tasks in a laboratory setting. Task-induced changes in fatigue dimensions were quantified using both subjective and objective measures, as were changes in performance on physical and mental tasks. Completing the simulated work tasks increased total fatigue, mental fatigue and physical fatigue in all experimental conditions. Higher physical fatigue adversely affected measures of physical and mental performance, whereas higher mental fatigue had a positive effect on one measure of mental performance. Overall, these results suggest causal effects between manipulated levels of mental and physical fatigue and task-induced changes in mental and physical performance. STATEMENT OF RELEVANCE: Nurse fatigue and performance has implications for patient and provider safety. Results from this study demonstrate the importance of a multidimensional view of fatigue in understanding the causal relationships between fatigue and performance. The findings can guide future work aimed at predicting fatigue-related performance decrements and designing interventions.

Race, space, place: notes on the racialisation and spatialisation of commercial sex work in Dubai, UAE.

Science.gov (United States)

Mahdavi, Pardis

2010-11-01

This paper focuses on the perceived racialisation and resultant spatialisation of commercial sex in Dubai. In recent years, the sex industry in Dubai has grown to include women from the Middle East, Eastern Europe, East Asia and Africa. With the increase in sex workers of different nationalities has come a form of localised racism that is embedded in structures and desires seen within specific locations. The physical spatialisation of sex work hinges on perceived race and produces distinct income generating potential for women engaged in the sex industry in Dubai. The social and physical topography of Dubai is important in marginalising or privileging these various groups of sex workers, which correlates race, space and place with rights and assistance. I begin with a description of the multidirectional flows of causality between race, space, place and demand. I then discuss how these various groups are inversely spatialised within the discourse on assistance, protection and rights. The findings presented here are based on ethnographic research conducted with transnational migrants in the UAE in 2004, 2008 and 2009.

The present research of cold-beating formation mainly focused on roller design and manufacture, kinematics, constitutive relation, metal flow law, thermo-mechanical coupling, surface micro-topography and microstructure evolution. However, the research on surface quality and performance of workpieces in the process of cold-beating is rare. Cold-beating simulation experiment of 1020 steel is conducted at room temperature and strain rates ranging from 2000 to 4000 s-1 base on the law of plastic forming. According to the experimental data, the model of strain hardening of 1020 steel is established, Scanning Electron Microscopy(SEM) is conducted, the mechanism of the work hardening of 1020 steel is clarified by analyzing microstructure variation of 1020 steel. It is found that the strain rate hardening effect of 1020 steel is stronger than the softening effect induced by increasing temperatures, the process of simulation cold-beating cause the grain shape of 1020 steel significant change and microstructure elongate significantly to form a fibrous tissue parallel to the direction of deformation, the higher strain rate, the more obvious grain refinement and the more hardening effect. Additionally, the change law of the work hardening rate is investigated, the relationship between dislocation density and strain, the relationship between work hardening rate and dislocation density is obtained. Results show that the change trend of the work hardening rate of 1020 steel is divided into two stages, the work hardening rate decreases dramatically in the first stage and slowly decreases in the second stage, finally tending toward zero. Dislocation density increases with increasing strain and strain rate, work hardening rate decreases with increasing dislocation density. The research results provide the basis for solving the problem of improving the surface quality and performance of workpieces under cold-beating formation of 1020 steel.

Oviedo, O A; Leiva, E P M; Mariscal, M M

2008-01-01

In the present work a detailed atomic-level analysis of some of the main diffusion mechanisms which take place during cobalt adatom deposition are studied within atom dynamics (AD) and the nudged elastic band (NEB) method. Our computer simulations reveal a very fast exchange between Co and Au atoms when the deposit is a single cobalt adatom. However, when the nucleus size increases, a decrease in the exchange probability is observed. Activation energies for different transitions are obtained using AD in combination with the NEB method

Work Practice Simulation of Complex Human-Automation Systems in Safety Critical Situations: The Brahms Generalized berlingen Model

2013-01-01

The transition from the current air traffic system to the next generation air traffic system will require the introduction of new automated systems, including transferring some functions from air traffic controllers to on­-board automation. This report describes a new design verification and validation (V&V) methodology for assessing aviation safety. The approach involves a detailed computer simulation of work practices that includes people interacting with flight-critical systems. The research is part of an effort to develop new modeling and verification methodologies that can assess the safety of flight-critical systems, system configurations, and operational concepts. The 2002 Ueberlingen mid-air collision was chosen for analysis and modeling because one of the main causes of the accident was one crew's response to a conflict between the instructions of the air traffic controller and the instructions of TCAS, an automated Traffic Alert and Collision Avoidance System on-board warning system. It thus furnishes an example of the problem of authority versus autonomy. It provides a starting point for exploring authority/autonomy conflict in the larger system of organization, tools, and practices in which the participants' moment-by-moment actions take place. We have developed a general air traffic system model (not a specific simulation of Überlingen events), called the Brahms Generalized Ueberlingen Model (Brahms-GUeM). Brahms is a multi-agent simulation system that models people, tools, facilities/vehicles, and geography to simulate the current air transportation system as a collection of distributed, interactive subsystems (e.g., airports, air-traffic control towers and personnel, aircraft, automated flight systems and air-traffic tools, instruments, crew). Brahms-GUeM can be configured in different ways, called scenarios, such that anomalous events that contributed to the Überlingen accident can be modeled as functioning according to requirements or in an

An innovative exercise method to simulate orbital EVA work - Applications to PLSS automatic controls

Science.gov (United States)

Lantz, Renee; Vykukal, H.; Webbon, Bruce

1987-01-01

An exercise method has been proposed which may satisfy the current need for a laboratory simulation representative of muscular, cardiovascular, respiratory, and thermoregulatory responses to work during orbital extravehicular activity (EVA). The simulation incorporates arm crank ergometry with a unique body support mechanism that allows all body position stabilization forces to be reacted at the feet. By instituting this exercise method in laboratory experimentation, an advanced portable life support system (PLSS) thermoregulatory control system can be designed to more accurately reflect the specific work requirements of orbital EVA.

Computational simulation of radiographic film

2013-01-01

The composition of a radiographic film gives its values of speed, spatial resolution and base density. The technical knowledge allows to predict how a film with a known composition works, and simulate how this film will work with changes in composition and exposure. In this paper, characterization of films composed by different emulsions was realized, in a way to know the characteristic curve, and to study how the format, organization and concentration of silver salt crystals set the radiographic film images.This work aims to increase an existing simulator, where parallel programming was used to simulate X-ray fluorescence processes. The setup of source and X-ray interactions with objects stills the same, and the detector constructed in this work was placed to form images. At first, considering the approach that the film is a square matrix where each element has a specific quantity of silver grains, that each grain fills a specific area, and that each interaction to radiation transforms a salt silver grain in to metallic silver grain (black grain), we have a blackening standard, and it should show how is the behavior of a optic density in a specific area of the film. Each matrix element has a degree of blackening, and it is proportional to the black grains area. (author)

Because of the complexity of real economic systems, the stochastic dependencies between different variables and parameters considered, not all systems can be adequately represented by a model that can be solved by analytical methods and covering all issues for management decision analysis-economic horizon real. Often in such cases, it is considered that the simulation technique is the only alternative available. Using simulation techniques to study real-world systems often requires a laborious work. Making a simulation experiment is a process that takes place in several stages.

Umezu, Yasuyoshi; Watanabe, Yuko; Ma, Ninshu

2005-08-01

Since 1996, Japan Research Institute Limited (JRI) has been providing a sheet metal forming simulation system called JSTAMP-Works packaged the FEM solvers of LS-DYNA and JOH/NIKE, which might be the first multistage system at that time and has been enjoying good reputation among users in Japan. To match the recent needs, "faster, more accurate and easier", of process designers and CAE engineers, a new metal forming simulation system JSTAMP-Works/NV is developed. The JSTAMP-Works/NV packaged the automatic healing function of CAD and had much more new capabilities such as prediction of 3D trimming lines for flanging or hemming, remote control of solver execution for multi-stage forming processes and shape evaluation between FEM and CAD. On the other way, a multi-stage multi-purpose inverse FEM solver HYSTAMP is developed and will be soon put into market, which is approved to be very fast, quite accurate and robust. Lastly, authors will give some application examples of user defined ductile damage subroutine in LS-DYNA for the estimation of material failure and springback in metal forming simulation.

Full Text Available The current upsurge of interest in street art with its direct approach to the city emphasizes the need to readdress public arts’ role within the wider social and cultural context. As it becomes routine to incorporate art works into city planning and city life, art has become both ‘safe’ and ‘user‐friendly’. On the one hand, art is subsumed and immersed into the wider culture through leisure and entertainment policies, socially engaged public art projects, community art and urban design. On the other hand, there are those works which deliberately intend to unsettle or confront the viewer. In recent years the term intervention has been ascribed to unorthodox art works in the public sphere which are often illicit, or at least non‐complicit in the prevailing hegemony. These practices are disruptive due to their enactment outside traditional art spaces, often in the streets. By occupying the streets, places of democracy and disjunction, these interventions transform public space back into a place of overt cultural and political expression. They also deliberately involve the inhabitants of the city by utilizing everyday spaces in ways which offer an unmediated sense of the artwork.

Place leadership, governance and power

Directory of Open Access Journals (Sweden)

Sotarauta Markku

2016-12-01

Full Text Available There is an emerging consensus that place leadership is the missing piece in the local and regional development puzzle. In this context, leadership is a hidden form of agency, shadowed by such visible forms of influence as structures and formal institutions, as well as development programs and plans. This article argues that one of the most central issues in a study of place leadership is to analyse the relationships between governance, power and place leadership. The governance arrangements are undoubtedly important, as they dictate the kind of resources and positions provided to regional development work, and thus they also enable, as well as constrain, the many efforts of regional champions to exercise power in complex development processes. It is argued here that revealing how place leadership is enacted in different places and times would allow us to flesh out novel aspects about the eternal questions of how and why some places are able to adapt strategically to ever-changing social, economic and environmental circumstances while others fail to do so. Additionally, deeper investigations of place leadership would hopefully allow us to provide policymakers and practitioners with added insight on the ways to make regional development policies and practices not only more strategic but also effective. This paper elaborates the conceptual link between place leadership, governance and power.

The objective of the present work is to give to know the most important characteristics in the Russian nuclear reactor of pressurized light water VVER-1000, doing emphasis in the differences that has with the western equivalent the reactor PWR in the design and the safety systems. Therefore, a description of the computerized simulation of the reactor VVER-1000 developed by the company Eniko TSO that the International Atomic of Energy Agency distributes to the states members with academic purposes will take place. The simulator includes mathematical models that represent to the essential systems in the real nuclear power plant, for what is possible to reproduce common faults and transitory characteristic of the nuclear industry with a behavior sufficiently attached to the reality. In this work is analyzed the response of the system before a turbine shot. After the accident in the nuclear power plant of Three Mile Island (US) they have been carried out improvements in the design of the reactor PWR and their safety systems. To know the reach and the limitations of the program, the events that gave place to this accident will be reproduced in the simulator VVER-1000. With base to the results of the simulation we will conclude that so reliable is the response of the safety system of this reactor. (Author)

Radon is a radioactive noble gas and is the decay product of naturally occurring uranium. It decays into radioactive metal ions polonium-218 and polonium-214 by alpha radiation, which are harmful to the human health. The concentrations of radon and its progeny inside a given working place depends on activity of radium both in the soil surrounding the workplace and in the building materials, atmospheric conditions, design of the workplace, porosity of the surrounding soil, building layout, and the ventilation habits of the inhabitants of the building. The estimation of dose due to radon and its progeny to the general public and workers at work places are very important. Thus, concentration of radon and its progeny and dose due to radon and its progeny to the public and workers were measured at sixty workplaces of Mysuru, Bengaluru, Tumkur and Kolar districts based on geology and willingness of the workplace owner using twin cup dosimeter based on Solid State Nuclear Track Detectors (SSNTDs) and results are discussed in the present study. The values measured indoor radon in the area of study ranged from a 11.6 to 284.8 Bq.m -3 . (author)

2006-01-01

The purpose of this document is to describe the GNC architecture and associated interfaces for all ARES simulations. Establishing a common architecture facilitates development across the ARES simulations and provides an efficient mechanism for creating an end-to-end simulation capability. In general, the GNC architecture is the frame work in which all GNC development takes place, including sensor and effector models. All GNC software applications have a standard location within the architecture making integration easier and, thus more efficient.

Dying at a favorite place is one of the important determinants for terminally ill cancer patients. The primary aim was to clarify (1) differences in preferred place of care and place of death among the general public across four areas across Japan and (2) preferred place of care and place of death among community-representative cancer patients. A cross-sectional mail survey was conducted on 8,000 randomly selected general population. We examined preferred place of care and place of death using two vignettes and obtained a total of 3,984 (50%) responses. For the pain scenario, approximately 50% of the general public throughout four areas chose home as their preferred place of care; and for the dependent-without-pain scenario, about 40% chose home as preferred place of care. In cancer patients, for both scenarios, approximately 40% chose home as the preferred place of care, and they were significantly less likely to choose home. The most preferred combination of place of care and place of death was home hospice for both groups. Although there were statistically significant differences in preferred place of care and place of death among the four regions, the absolute difference was less than 8%. Independent determinants of choosing home as place of care included concern about family burden and being unable to adequately respond to sudden changes out of working hours. In conclusion, establishing more accessible home and hospice service is strongly required through arranging regional resources to reduce family burden, alleviating patient-perceived burdens, and improving 24-h support at home.

Inventing and naming America:  Place and Place Names in Vladimir Nabokov’s Lolita

Directory of Open Access Journals (Sweden)

Monica Manolescu-Oancea

2009-06-01

Full Text Available In the afterword to Lolita, Nabokov claimed that in this book he had to invent both Lolita and America after having invented Europe in his previous fiction. This paper focuses precisely on the various ways in which Nabokov “invented” America in his best-known novel. This invention is first of all the result of the author’s evolving stance on the complexity of what he called “average ‘reality’” in his works. Through a survey of Nabokov’s statements on the choice and role of place in the forewords to his Russian works and in his critical texts, I show that Lolita is indeed considered by Nabokov to be a “recreation” of American reality, to a much greater extent than his Russian works had been recreations of a given milieu. I take the metaphor of the “crazy quilt” mentioned in Lolita to suggest complexity, chromatic exuberance, hybridity. The invention of America is also the result of a process of naming. Place names will be examined, not only those which make up Quilty’s “cryptogrammic paperchase”, but also Humbert’s choice of place names. The problem of referentiality is discussed and the way recent criticism has dealt with it. Finally, the interplay between one and many is emphasized, the way in which the diversity of the “crazy quilt” is counterbalanced by the uniqueness of the mastermind having produced it. The American motto “From many make one” could be reinterpreted as “From one make many”.

The place of conformal radiotherapy in the routine work: national investigation of SFRO members'opinion

International Nuclear Information System (INIS)

Lagrange, J.L.; Lipinski, F.

2001-01-01

National French investigation of the using of conformal radiotherapy in routine work, has been made in 2001, in 180 radiotherapeutic centers. Eighty responses have been obtained and analyzed. Conformal radiotherapy is used in 88% and virtual simulation in 60% of these centers. There is a heterogeneity in the equipment of these institutions, most of them have one or two machines. The accelerator equipment differs, and the availability of multi-leaf collimators and electronic portal imaging is limited. Actually only eleven centers have IMRT, eight have projects to install. Only six centers have CT-scans, used mainly for simulation. In 75% of centers conformal radiotherapy have been used in the treatment of CNS-tumors, head and neck cancers, prostate, and non-small cell lung carcinoma. If there are more equipment and human facilities to use conformal radiotherapy, this treatment can be proposed to patients with breast cancer, rectal and gynecological tumors. According 90% of responses, all prostatic cancers need conformal radiotherapy. The analysis of routine use of conformal radiotherapy in France shows an important heterogeneity but it seems that there is an agreement with objectives of this treatment. (authors)

Simulation-based skill trainings are common; however, optimal instructional designs that improve outcomes are not well specified. We explored the impact of just-in-time and just-in-place training (JIPT) on interns' infant lumbar puncture (LP) success. This prospective study enrolled pediatric and emergency medicine interns from 2009 to 2012 at 34 centers. Two distinct instructional design strategies were compared. Cohort A (2009-2010) completed simulation-based training at commencement of internship, receiving individually coached practice on the LP simulator until achieving a predefined mastery performance standard. Cohort B (2010-2012) had the same training plus JIPT sessions immediately before their first clinical LP. Main outcome was LP success, defined as obtaining fluid with first needle insertion and <1000 red blood cells per high-power field. Process measures included use of analgesia, early stylet removal, and overall attempts. A total of 436 first infant LPs were analyzed. The LP success rate in cohort A was 35% (13/37), compared with 38% (152/399) in cohort B (95% confidence interval for difference [CI diff], -15% to +18%). Cohort B exhibited greater analgesia use (68% vs 19%; 95% CI diff, 33% to 59%), early stylet removal (69% vs 54%; 95% CI diff, 0% to 32%), and lower mean number of attempts (1.4 ± 0.6 vs 2.1 ± 1.6, P < .01) compared with cohort A. Across multiple institutions, intern success rates with infant LP are poor. Despite improving process measures, adding JIPT to training bundles did not improve success rate. More research is needed on optimal instructional design strategies for infant LP. Copyright © 2015 by the American Academy of Pediatrics.

CFD SIMULATION OF AIR ION REGIME IN WORK AREAS AT CONDITION OF ARTIFICIAL AIR IONIZATION

Directory of Open Access Journals (Sweden)

M. M. Biliaiev

2016-02-01

Full Text Available Purpose. The paper supposes creation of a CFD model for calculating the air ion regime in the premises and in work areas at artificial ionization of the air by the ionizer installation indoors with considering the most important physical factors that influence the formation of ions concentration field. Methodology. The proposed CFD model for calculation of the air ion regime in work areas at artificial ionization of the air by installing ionizer indoors is based on the application of aerodynamics, electrostatics and mass transfer equations. The mass transfer equation takes into account the interaction of different polarities of ions with each other and with the dust particles. The calculation of air flow rate in the room is realized on the basis of the potential flow model by using the Laplace equation for the stream function. Poisson equation for the electric potential is used for calculation of the charged particles drift in an electric field. At the simulation to take into account: 1 influence of the working area geometric characteristics; 2 location of the ventilation holes; 3 placement of furniture and equipment; 4 ventilation regime in the room; 5 presence of obstacles on the ions dispersion process; 6 specific location of dust particles emission and ions of different polarity, and their interaction in the room and in the working zones. Findings. The developed CFD model allows determining the concentration of negative ions in the room and in the area of the human respiratory organs. The distribution of the negative ions concentration is presented in the form of concentration field isolines. Originality. The 2D CFD model for calculating the air ion regime in working areas, providing the ability to determine the ions concentration in a given place in the room was created. The proposed model is developed taking into account: placement of furniture and equipment in the room; geometric characteristics of the room; location of dust emissions

Full Text Available This article reviews Matthews’ (2014 Realist Criminology as an opportunity to address larger shortcomings within critical criminology, which is the failure to develop an alternative theory of crime and place to the mainstream theories of social disorganisation and collective efficacy. It uses rural criminological work related to violence against women and substance use, production and trafficking to illustrate the importance of place for development of a realist criminology that can consider localised expressions of power and inequality, and the multiplicity of networks and roles by which people can simultaneously be involved in both conforming and deviant/criminal behaviours. The article also suggests that a critical theory of crime and place would be useful to the synthesis and re-interpretation of criminological literature that is either theory-less or lacks a critical perspective.

To investigate the effects of night work and sleep loss on a simulated luggage screening task (SLST) that mimicked the x-ray system used by airport luggage screeners. We developed more than 5,800 unique simulated x-ray images of luggage organized into 31 stimulus sets of 200 bags each. 25% of each set contained either a gun or a knife with low or high target difficulty. The 200-bag stimuli sets were then run on software that simulates an x-ray screening system (SLST). Signal detection analysis was used to obtain measures of hit rate (HR), false alarm rate (FAR), threat detection accuracy (A'), and response bias (B"(D)). Experimental laboratory study 24 healthy nonprofessional volunteers (13 women, mean age +/- SD = 29.9 +/- 6.5 years). Subjects performed the SLST every 2 h during a 5-day period that included a 35 h period of wakefulness that extended to night work and then another day work period after the night without sleep. Threat detection accuracy A' decreased significantly (P work, while both A' (P = 0.001) and HR decreased (P = 0.008) during day work following sleep loss. There were prominent time-on-task effects on response bias B"(D) (P= 0.002) and response latency (P = 0.004), but accuracy A' was unaffected. Both HR and FAR increased significantly with increasing study duration (both P work and sleep loss adversely affect the accuracy of detecting complex real world objects among high levels of background clutter. If the results can be replicated in professional screeners and real work environments, fatigue in luggage screening personnel may pose a threat for air traffic safety unless countermeasures for fatigue are deployed.

PACS or the future of the radiologist's working place

International Nuclear Information System (INIS)

Meyer-Ebrecht, D.

1988-01-01

PACS (picture archiving and communication systems) is a synonym for the replacement of the traditional photographic film by means of technologies that will communicate and store images exclusively in digital form. Digital mass storage will replace the film archives and will be linked to all image sources by means of a data communication network. More significantly, PACS will also introduce a novel type of image-evaluation modality, the diagnostic image work station. Images will be displayed on TV monitors. In addition, a variety of support functions will become available for image handling and processing. The replacement of the light box by a digital work station will definitely cause dramatic changes in the radiologist's work. (orig.) [de

[Municipalities as places for social work for the elderly].

Science.gov (United States)

Rüßler, Harald; Heite, Elisabeth

2017-07-01

Against the background of social and demographic changes, this article addresses the design and organization of processes of aging within municipal contexts. It is assumed that the renaissance of the local communal situation corresponds to processes of individualization and subjectivation, which are characteristic for (post)industrial western societies, and that this development is one of the reasons that community-based social work is regaining importance. A case study of social work for the elderly in a municipality of the Ruhr area, which is imbedded in a municipal senior citizens policy concept, illustrates this assumption. The conclusion identifies the scope of actions for social work for the elderly as well as their limitations.

Reliability of analog quantum simulation

Energy Technology Data Exchange (ETDEWEB)

Analog quantum simulators (AQS) will likely be the first nontrivial application of quantum technology for predictive simulation. However, there remain questions regarding the degree of confidence that can be placed in the results of AQS since they do not naturally incorporate error correction. Specifically, how do we know whether an analog simulation of a quantum model will produce predictions that agree with the ideal model in the presence of inevitable imperfections? At the same time there is a widely held expectation that certain quantum simulation questions will be robust to errors and perturbations in the underlying hardware. Resolving these two points of view is a critical step in making the most of this promising technology. In this work we formalize the notion of AQS reliability by determining sensitivity of AQS outputs to underlying parameters, and formulate conditions for robust simulation. Our approach naturally reveals the importance of model symmetries in dictating the robust properties. To demonstrate the approach, we characterize the robust features of a variety of quantum many-body models. (orig.)

The foregrounding of place in Trainspotting

(2003), Johnstone (2009, 2010, 2013), and Eckert’s (2008) work on indexicality, we argue that these linguistic features in Trainspotting function as indexical markers connecting the characters and the novel to place, more specifically to Scotland. In the analysis, we explore three channels through which...... the foregrounding of place is evident. First, the foregrounding of place happens through the sheer volume of nonstandard English associated with Scots throughout the novel in that the extensive appearance of nonstandard English deviates from most novels, and in that the nonstandard variety indexes Scotland. Second...... of place happens through the ideology that favours Standard English over nonstandard English. This channel of foregrounding appears through the characters’ ability or inability to style-shift between nonstandard English and Standard English, and the effects of the ability or inability to do so. We argue...

Cultures of simulations vs. cultures of calculations? The development of simulation practices in meteorology and astrophysics

Science.gov (United States)

Sundberg, Mikaela

While the distinction between theory and experiment is often used to discuss the place of simulation from a philosophical viewpoint, other distinctions are possible from a sociological perspective. Turkle (1995) distinguishes between cultures of calculation and cultures of simulation and relates these cultures to the distinction between modernity and postmodernity, respectively. What can we understand about contemporary simulation practices in science by looking at them from the point of view of these two computer cultures? What new questions does such an analysis raise for further studies? On the basis of two case studies, the present paper compares and discusses simulation activities in astrophysics and meteorology. It argues that simulation practices manifest aspects of both of these cultures simultaneously, but in different situations. By employing the dichotomies surface/depth, play/seriousness, and extreme/reasonable to characterize and operationalize cultures of calculation and cultures of simulation as sensitizing concepts, the analysis shows how simulation code work shifts from development to use, the importance of but also resistance towards too much visualizations, and how simulation modelers play with extreme values, yet also try to achieve reasonable results compared to observations.

Work rehabilitation programs targeting different client groups are available in nearly all major hospital occupational therapy departments in Hong Kong. Clients receiving work rehabilitation are referred from various out-patient clinics and other occupational therapists. Those clients experience limitation in work after their injuries or diseases and plan to return to work after rehabilitation. Program objectives are 1) to assist clients to reach maximum work capacity as rapidly as possible 2) to ensure clients return to work safely 3) to improve clients' work readiness. This case report describes an individualized work simulation program at a general hospital in Hong Kong provided for a typical client who is preparing to return to his worker role. Specific job analysis, goals and program rationale for the client are discussed.

Controlled patterns of daytime light exposure improve circadian adjustment in simulated night work.

Dumont, Marie; Blais, Hélène; Roy, Joanie; Paquet, Jean

2009-10-01

Circadian misalignment between the endogenous circadian signal and the imposed rest-activity cycle is one of the main sources of sleep and health troubles in night shift workers. Timed bright light exposure during night work can reduce circadian misalignment in night workers, but this approach is limited by difficulties in incorporating bright light treatment into most workplaces. Controlled light and dark exposure during the daytime also has a significant impact on circadian phase and could be easier to implement in real-life situations. The authors previously described distinctive light exposure patterns in night nurses with and without circadian adaptation. In the present study, the main features of these patterns were used to design daytime light exposure profiles. Profiles were then tested in a laboratory simulation of night work to evaluate their efficacy in reducing circadian misalignment in night workers. The simulation included 2 day shifts followed by 4 consecutive night shifts (2400-0800 h). Healthy subjects (15 men and 23 women; 20-35 years old) were divided into 3 groups to test 3 daytime light exposure profiles designed to produce respectively a phase delay (delay group, n=12), a phase advance (advance group, n=13), or an unchanged circadian phase (stable group, n=13). In all 3 groups, light intensity was set at 50 lux during the nights of simulated night work. Salivary dim light melatonin onset (DLMO) showed a significant phase advance of 2.3 h (+/-1.3 h) in the advance group and a significant phase delay of 4.1 h (+/-1.3 h) in the delay group. The stable group showed a smaller but significant phase delay of 1.7 h (+/-1.6 h). Urinary 6-sulfatoxymelatonin (aMT6s) acrophases were highly correlated to salivary DLMOs. Urinary aMT6s acrophases were used to track daily phase shifts. They showed that phase shifts occurred rapidly and differed between the 3 groups by the 3rd night of simulated night work. These results show that significant phase shifts can

Employees working across multiple cultures are exposed to a vast number of different norms and values, and consequentially work is often a struggle to retain a coherent sense of self. However, when international workers travel, they also encounter more bland spaces where familiarity and similarity...... are important. These spaces appear culturally generic to the Western traveler, but are highly Westernized to bring comfort to Western employees traveling in foreign cultures. This paper argues that these spaces are important in cross-cultural identity work in the sense that international workers – professional...... strangers – need these places to belong and relate to familiarity and to regain a sense of identity. Drawing on an illustrative empirical vignette of an international consultant, I demonstrate how culturally generic spaces can be used in identity work of an international relations consultant....

This paper describes the latest developments at the Institute for Energy Technology (IFE) in Norway, in the field of real-time 3D (three-dimensional) radiation risk assessment for the support of work simulation in nuclear environments. 3D computer simulation can greatly facilitate efficient work planning, briefing, and training of workers. It can also support communication within and between work teams, and with advisors, regulators, the media and public, at all the stages of a nuclear installation’s lifecycle. Furthermore, it is also a beneficial tool for reviewing current work practices in order to identify possible gaps in procedures, as well as to support the updating of international recommendations, dissemination of experience, and education of the current and future generation of workers. IFE has been involved in research and development into the application of 3D computer simulation and virtual reality (VR) technology to support work in radiological environments in the nuclear sector since the mid 1990s. During this process, two significant software tools have been developed, the VRdose system and the Halden Planner, and a number of publications have been produced to contribute to improving the safety culture in the nuclear industry. This paper describes the radiation risk assessment techniques applied in earlier versions of the VRdose system and the Halden Planner, for visualising radiation fields and calculating dose, and presents new developments towards implementing a flexible and up-to-date dosimetric package in these 3D software tools, based on new developments in the field of radiation protection. The latest versions of these 3D tools are capable of more accurate risk estimation, permit more flexibility via a range of user choices, and are applicable to a wider range of irradiation situations than their predecessors.

A simulation model is developed by commercial simulators in order to predict the performance of a fluidised bed reformer. As many physical and chemical phenomena take place in the reformer, two sub-models (hydrodynamic and reaction sub-models) are needed. The hydrodynamic sub-model is based on the dynamic two-phase model and the reaction sub-model is derived from the literature. In the overall model, the bed is divided into several sections. In each section, the flow of the gas is considered as plug flow through the bubble phase and perfectly mixed through the emulsion phase. Experimental data from the literature were used to validate the model. Close agreement was found between the model of both ASPEN Plus (ASPEN PLUS 2004 ©) and HYSYS (ASPEN HYSYS 2004 ©) and the experimental data using various sectioning of the reactor ranged from one to four. The experimental conversion lies between one and four sections as expected. The model proposed in this work can be used as a framework in developing the complicated models for non-ideal reactors inside of the process simulators.

Working as simulated patient has effects on real patient life – Preliminary insights from a qualitative study

Directory of Open Access Journals (Sweden)

Simmenroth-Nayda, Anne

2016-05-01

Full Text Available Background: Persons who simulate patients during medical education understand the routines and the underlying script of medical consultations better. We aimed to explore how simulated patients (SPs integrated this new understanding into their daily life, how this work affected their private life as patients, and what we can learn from these changes for concepts of empowerment.Design, setting, and participants: A qualitative interview study. All SPs of Göttingen medical school who had been working longer than three semesters (n=14 were invited and agreed to take part in an open interview about their daily experience with real doctors. Documentary method was used to identify the main issues. Several cases were chosen according to maximum contrast and analysed by in-depth analysis to provide vivid examples of how simulations may affect the real life of the SPs as patients.Results: Our analysis revealed three main changes in the behaviour of SPs as real patients. They were more attentive, had a better understanding of the circumstances under which doctors work, and acted more self-confidently. From the selected cases it became apparent that working as a SP may lead to a constant and significant decrease of fear of hospitals and medical procedures or, in other cases, may enable the SPs to develop new abilities for giving feedback, questioning procedures, and explanations for real doctors.Conclusion: working as a simulated patient seems to be well-suited to understand own progression of diseases, to increase self-responsibility and to a confident attitude as patient.

Prototype simulates remote sensing spectral measurements on fruits and vegetables

Science.gov (United States)

Hahn, Federico

1998-09-01

A prototype was designed to simulate spectral packinghouse measurements in order to simplify fruit and vegetable damage assessment. A computerized spectrometer is used together with lenses and an externally controlled illumination in order to have a remote sensing simulator. A laser is introduced between the spectrometer and the lenses in order to mark the zone where the measurement is being taken. This facilitates further correlation work and can assure that the physical and remote sensing measurements are taken in the same place. Tomato ripening and mango anthracnose spectral signatures are shown.

Simulator testing system (STS)

Miller, V.N.

1990-01-01

In recent years there has been a greater demand placed on the capabilities and time usage of real-time nuclear plant simulators due to NRC, INPO and utilities requirements. The requirements applied to certification, new simulators, upgrades, modifications, and maintenance of the simulators vary; however, they all require the capabilities of the simulator to be tested whether it is for NRC 10CFR55.45b requirements, ATP testing of new simulators, ATP testing of upgrades with or without panels, adding software/hardware due to plant modifications, or analyzing software/hardware problems on the simulator. This paper describes the Simulator Testing System (STS) which addresses each one of these requirements placed on simulators. Special attention will be given to ATP testing of upgrades without the use of control room panels. The capabilities and applications of the four parts of STS which are the Display Control Software (DCS), Procedure Control Software (PCS), Display Generator Software (DGS) and the Procedure Generator Software (PGS) will be reviewed

Applications of simulation experiments in LMFBR core materials technology

International Nuclear Information System (INIS)

Appleby, W.K.

1976-01-01

The development of charged particle bombardment experiments to simulate neutron irradiation induced swelling in austenitic alloys is briefly described. The applications of these techniques in LMFBR core materials technology are discussed. It is shown that use of the techniques to study the behavior of cold-worked Type-316 was instrumental in demonstrating at an early date the need for advanced materials. The simulation techniques then were used to identify alloying elements which can markedly decrease swelling and thus a focused reactor irradiation program is now in place to allow the future use of a lower swelling alloy for LMFBR core components

In-place testing of hydraulic snubbers

International Nuclear Information System (INIS)

Raymont, J.M. Jr.

1986-01-01

Over the last few years, an increasing number of utilities have implemented periodic in-service inspection (ISI) programs of their hydraulic snubbers. This thrust has caused the nuclear power industry to seek cost-effective means of testing hydraulic snubbers. This paper reviews the following aspects of in-place testing and develops a technical justification for its use as a viable alternative to test bench testing. (1) A detailed examination of how in-place testing works is provided. Discussed are the hydraulic principles, fluid flow paths, and snubber test setup. (2) A comparison of the test bench and in-place test machines is provided. The discussion reviews the similarities and differences between the two test methods as well as the test results. (3) The need for correlation of in-place test results back to test bench data with a snubber footprint is discussed. (4) The issue of partial load testing with extrapolation to full load testing is discussed and compared with full load testing. The hydraulic principles as well as the costs and benefits of partial load versus full load testing are compared. (5) In-place test machine technology is reviewed. The operating principles, accuracies, and limitations are presented. (6) Actual test data are provided and reviewed on a test-by-test basis. (7) Lessons learned from actual in-place test jobs are reviewed. (8) In-place test procedures and calibration practices are outlined to illustrate the nature of the required planning on the part of the utility

Assessing the Driver's Current Level of Working Memory Load with High Density Functional Near-infrared Spectroscopy: A Realistic Driving Simulator Study.

Cognitive overload or underload results in a decrease in human performance which may result in fatal incidents while driving. We envision that driver assistive systems which adapt their functionality to the driver's cognitive state could be a promising approach to reduce road accidents due to human errors. This research attempts to predict variations of cognitive working memory load levels in a natural driving scenario with multiple parallel tasks and to reveal predictive brain areas. We used a modified version of the n-back task to induce five different working memory load levels (from 0-back up to 4-back) forcing the participants to continuously update, memorize, and recall the previous 'n' speed sequences and adjust their speed accordingly while they drove for approximately 60 min on a highway with concurrent traffic in a virtual reality driving simulator. We measured brain activation using multichannel whole head, high density functional near-infrared spectroscopy (fNIRS) and predicted working memory load level from the fNIRS data by combining multivariate lasso regression and cross-validation. This allowed us to predict variations in working memory load in a continuous time-resolved manner with mean Pearson correlations between induced and predicted working memory load over 15 participants of 0.61 [standard error (SE) 0.04] and a maximum of 0.8. Restricting the analysis to prefrontal sensors placed over the forehead reduced the mean correlation to 0.38 (SE 0.04), indicating additional information gained through whole head coverage. Moreover, working memory load predictions derived from peripheral heart rate parameters achieved much lower correlations (mean 0.21, SE 0.1). Importantly, whole head fNIRS sampling revealed increasing brain activation in bilateral inferior frontal and bilateral temporo-occipital brain areas with increasing working memory load levels suggesting that these areas are specifically involved in workload-related processing.

The aim of our study was to explore the major non-communicable risk factors (unhealthy diet, sedentarily, alcohol consumption) of smokers and nonsmokers in workplaces. A cross-sectional study was derived from an initial assessment in workplaces which was part of a community-based intervention to prevent chronic disease risk factors conducted in 2009 in the region of Sousse, Tunisia. The surveyed subjects were employees in six factories spread across three delegations in the region. Overall, 1770 of 2250 employees participated in the assessment. In this study, the clustering of non-communicable diseases risk factors with smoking habits was made only for male employees including in this study 1099 among 2250. Data were collected at worksites by a questionnaire, via interview or self-report. The main items assessed socio-demographics characteristics, smoking status, eating habits, level of physical activity and alcohol use of the participants. The percentage of male smokers was 54.0%(n=594). Their average age of daily smoking initiation was 19.22 (±4.24 years). The percentage of male smokers consuming 5 fruits and vegetables per day was significantly lower than nonsmokers (57.2% vs 63.5%, p=0.04). The proportion of male smokers consuming alcohol was about three times that of nonsmokers (16.5% vs 5.8%, p=0.001). The proportion of male employees who agree with anti-smoking laws in work places was higher for nonsmokers than for smokers. A strong association existed between smoking and risky lifestyles factors in the work place. Such findings are potentially useful in directing intervention efforts regarding smoking cessation in occupational settings.

For absorption refrigeration, it has been shown that ionic liquids have the potential to replace conventional working pairs. Due to the huge number of possibilities, conducting lab experiments to find the optimal ionic liquid is infeasible. Here, we provide a proof-of-principle study of an alternative computational approach. The required thermodynamic properties, i.e., solubility, heat capacity, and heat of absorption, are determined via molecular simulations. These properties are used in a model of the absorption refrigeration cycle to estimate the circulation ratio and the coefficient of performance. We selected two ionic liquids as absorbents: [emim][Tf 2 N], and [emim][SCN]. As refrigerant NH 3 was chosen due to its favorable operating range. The results are compared to the traditional approach in which parameters of a thermodynamic model are fitted to reproduce experimental data. The work shows that simulations can be used to predict the required thermodynamic properties to estimate the performance of absorption refrigeration cycles. However, high-quality force fields are required to accurately predict the cycle performance.

From sense of place to visualization of place: examining people-place relationships for insight on developing geovisualizations.

Science.gov (United States)

Newell, Robert; Canessa, Rosaline

2018-02-01

Effective resource planning incorporates people-place relationships, allowing these efforts to be inclusive of the different local beliefs, interests, activities and needs. 'Geovisualizations' can serve as potentially powerful tools for facilitating 'place-conscious' resource planning, as they can be developed with high degrees of realism and accuracy, allowing people to recognize and relate to them as 'real places'. However, little research has been done on this potential, and the place-based applications of these visual tools are poorly understood. This study takes steps toward addressing this gap by exploring the relationship between sense of place and 'visualization of place'. Residents of the Capital Regional District of BC, Canada, were surveyed about their relationship with local coastal places, concerns for the coast, and how they mentally visualize these places. Factor analysis identified four sense of place dimensions - nature protection values, community and economic well-being values, place identity and place dependence, and four coastal concerns dimensions - ecological, private opportunities, public space and boating impacts. Visualization data were coded and treated as dependent variables in a series of logistic regressions that used sense of place and coastal concerns dimensions as predictors. Results indicated that different aspects of sense of place and (to a lesser degree) concerns for places influence the types of elements people include in their mental visualization of place. In addition, sense of place influenced the position and perspective people assume in these visualizations. These findings suggest that key visual elements and perspectives speak to different place relationships, which has implications for developing and using geovisualizations in terms of what elements should be included in tools and (if appropriate) depicted as affected by potential management or development scenarios.

Current mental health policy emphasizes the importance of community-based service delivery for people with mental health problems to encompass personal recovery. The aim of this study is to explore how users and professionals construct the place's influence on personal recovery in community mental health services. This is a qualitative, interpretive study based on ten individual, semi-structured interviews with users and professionals, respectively. A discourse analysis inspired by the work of Foucault was used to analyze the interviews. The findings show how place can be constructed as a potential for and as a barrier against recovery. Constructions of the aim of the services matter when choosing a place for the services. Further, constructions of user-professional relationships and flexibility are important in the constructions of an appropriate place for the services. The aim of the service, the user-professional relationship, and flexibility in choosing place were essential in the participants' constructions. To find "the right place" for mental health services was constructed as context-sensitive and complex processes of assessment and co-determination. Trial registration The study is approved by the Regional Committee for Medical Research Ethics, Norway (REK-Midt 2011/2057).

2017-06-01

In this work, a simulation toolset for Computer Aided Inspection Planning (CAIP) of systems for automated optical inspection (AOI) is presented along with a versatile two-robot-setup for verification of simulation and system planning results. The toolset helps to narrow down the large design space of optical inspection systems in interaction with a system expert. The image formation taking place in optical inspection systems is simulated using GPU-based real time graphics and high quality off-line-rendering. The simulation pipeline allows a stepwise optimization of the system, from fast evaluation of surface patch visibility based on real time graphics up to evaluation of image processing results based on off-line global illumination calculation. A focus of this work is on the dependency of simulation quality on measuring, modeling and parameterizing the optical surface properties of the object to be inspected. The applicability to real world problems is demonstrated by taking the example of planning a 3D laser scanner application. Qualitative and quantitative comparison results of synthetic and real images are presented.

The naturally fractured reservoir recovery normally involves risk especially in intermediate to oil wet systems because of the simulations poor efficiency results under waterflood displacement. Double-porosity models are generally used in fractured reservoir simulation and have been implemented in the major commercial reservoir simulators. The physical processes acting in petroleum recovery are represented in double-porosity models by matrix-fracture transfer functions, therefore commercial simulators have their own implementations, and as a result different kinetics and final recoveries are attained. In this work, a double porosity simulator was built with Kazemi et al. (1976), Sabathier et al. (1998) and Lu et al. (2008) transfer function implementations and their recovery results have been compared using waterflood displacement in oil-wet or intermediate-wet systems. The results of transfer function comparisons have showed recovery improvements in oil-wet or intermediate-wet systems under different physical processes combination, particularly in fully discontinuous porous medium when concurrent imbibition takes place, coherent with Firoozabadi (2000) experimental results. Furthermore, the implemented transfer functions, related to a double-porosity model, have been compared to double-porosity commercial simulator model, as well a discrete fracture model with refined grid, showing differences between them. Waterflood can be an effective recovery method even in fully discontinuous media for oil-wet or intermediate-wet systems where concurrent imbibition takes place with high enough pressure gradients across the matrix blocks.

The passive beam delivery system in the superficially-placed tumor therapy terminal at Heavy Ion Research Facility in Lanzhou (HIRFL), which includes two orthogonal dipole magnets as scanning system, a motor-driven energy degrader as range-shifter, series of ridge filters as range modulator and a multileaf collimator, is introduced in detail. The capacities of its important components and the whole system have been verified experimentally. The tests of the ridge filter for extending Bragg peak and the range shifter for energy adjustment show both work well. To examine the passive beam delivery system, a beam shaping experiment were carried out, simulating a three-dimensional (3D) conformal irradiation to a tumor. The encouraging experimental result confirms that 3D layer-stacking conformal irradiation can be performed by means of the passive system. The validation of the beam delivery system establishes a substantial basis for upcoming clinical trial for superficially-placed tumors with heavy ions in the therapy terminal at HIRFL. (authors)

Cognitive overload or underload results in a decrease in human performance which may result in fatal incidents while driving. We envision that driver assistive systems which adapt their functionality to the driver’s cognitive state could be a promising approach to reduce road accidents due to human errors. This research attempts to predict variations of cognitive working memory load levels in a natural driving scenario with multiple parallel tasks and to reveal predictive brain areas. We used a modified version of the n-back task to induce five different working memory load levels (from 0-back up to 4-back) forcing the participants to continuously update, memorize, and recall the previous ‘n’ speed sequences and adjust their speed accordingly while they drove for approximately 60 min on a highway with concurrent traffic in a virtual reality driving simulator. We measured brain activation using multichannel whole head, high density functional near-infrared spectroscopy (fNIRS) and predicted working memory load level from the fNIRS data by combining multivariate lasso regression and cross-validation. This allowed us to predict variations in working memory load in a continuous time-resolved manner with mean Pearson correlations between induced and predicted working memory load over 15 participants of 0.61 [standard error (SE) 0.04] and a maximum of 0.8. Restricting the analysis to prefrontal sensors placed over the forehead reduced the mean correlation to 0.38 (SE 0.04), indicating additional information gained through whole head coverage. Moreover, working memory load predictions derived from peripheral heart rate parameters achieved much lower correlations (mean 0.21, SE 0.1). Importantly, whole head fNIRS sampling revealed increasing brain activation in bilateral inferior frontal and bilateral temporo-occipital brain areas with increasing working memory load levels suggesting that these areas are specifically involved in workload-related processing.

Full Text Available As the aesthetic of the Polish cities became a topic of wider discussions, it is important to detect the potential role of human-place relations. Two studies (N = 185 & N = 196 were conducted to explore the relationship between place attachment, place identity and appraisal of urban landscape. Satisfaction with urban aesthetic was predicted by two dimensions of place attachment (place inherited and place discovered, local identity (on the trend level and national-conservative identity. Place discovered and European identity were also predictors of visual pollution sensitivity. Place discovered is considered as more active type of attachment that permits both a positive bias concerning the aesthetics of one’s city, and a stronger criticism of the elements that can potentially violate the place’s landscape.

Full Text Available Michel Foucault in the text “Of Other Spaces: Utopias and Heterotopias” wrote that “the present epoch will perhaps be above all the epoch of space”. Space, place, and territories are social productions. Territory is a polysemic concept. Place is “events” created by territories, fluid areas of control produced by territorial negotiation (horizontal dynamics and negotiations between places (vertical dynamics. Space produces places and is produced by places. Moreover, space, place and territories can be seen as the waves of territorialization and deterritorialization in an endless process. It is a form of seizure in the world, an a priori for Immanuel Kant, an ontological need for Martin Heidegger. Territory is a space, governed by a set of rules, named “code”. Territorialization is then synonymous of a certain codification, or the symbolical organization of space. Places are created by territorializational dynamics. They are the sum of “events”. The place and its territory is not “natural”, but it is a cultural artifact, a social product linked to desire, power and identity. The changes of the functions of places (what Foucault called heterotopy are an important subject of contemporary studies. There are also many new temporary uses of these spaces and different emerging functions, including new forms of control, access, surveillance, new forms of openness and closeness (passwords, access profiles, etc.. Informational territory creates new heterotopias, new functions for places and a redefinition of social and communicational practices. It is not the end of a concrete place and its territory, but rather, a new meaning, sense, and a function for these spaces. The contemporary meaning of place and space has a visible tendency in creating ambivalence of sacrum and profanum, which means the secularization of the sacred and the sacralization of the secular. One of the sides of this tendency is sacralizing market and marketing

The use of simulation as an educational tool is becoming more widespread in healthcare. Such training gathers doctors and nurses together, which is a rare opportunity in such a sector. The present research focuses on the contribution of inter-professional training to the development of collaborative skills when managing an emergency situation in the context of anesthesia or intensive care. From direct observations of post-simulation debriefing sessions and interviews held with learners in post graduate or in-service training, either in single or multi-professional groups, this study shows that these sessions, based on experiential learning and reflective practice, help to build a shared vision of the problem and of common operative patterns, supporting better communication and the "ability to work in a team".

Krekic, Valerija Pinter; Namestovski, Zolt

2009-01-01

According to Aebli's operative method (1963) and Bruner's (1974) theory of representation the development of the process of thinking in teaching has the following phases - levels of abstraction: manipulation with specific things (specific phase), iconic representation (figural phase), symbolic representation (symbolic phase). Modern information technology has contributed to the enrichment of teaching and learning processes, especially in the fields of natural sciences and mathematics and those of production and technology. Simulation appears as a new possibility in the representation of knowledge. According to Guetzkow (1972) simulation is an operative representation of reality from a relevant aspect. It is about a model of an objective system, which is dynamic in itself. If that model is material it is a simple simulation, if it is abstract it is a reflective experiment, that is a computer simulation. This present work deals with the systematization and classification of simulation methods in the teaching of natural sciences and mathematics and of production and technology with special retrospective view on computer simulations and exemplar representation of the place and the role of this modern method of cognition. Key words: Representation of knowledge, modeling, simulation, education

Decontamination factor is calculated after five cleaning for each group. A total of 160 samples result calculated using four decontaminating agent (tap water, SW, Radiacwash, and spirit), four swipe material (cotton, TP, WP, and AS) for commonly used surface (stainless steel, PVC, Perspex, resin) using direct method by 10 samples (n = 10) for each group. Tap water is the best decontaminating agent compared with SW, Radiac wash and spirit for the laboratory simulated stainless steel, PVC, and Perspex surface material, whereas in case of resin surface material, SW decontaminating agent is showing better effectiveness. Cotton is the best swipe material compared to WP-1, AS and TP for the stainless steel, PVC, Perspex, and resin laboratory simulated surface materials. Perspex and stainless steel are the most suitable and recommended laboratory surface material compared to PVC and resin in nuclear medicine

Thin Places

OpenAIRE

Lockwood, Sandra Elizabeth

2013-01-01

This inquiry into the three great quests of the twentieth century–the South Pole, Mount Everest, and the Moon–examines our motivations to venture into these sublime, yet life-taking places. The Thin Place was once the destination of the religious pilgrim seeking transcendence in an extreme environment. In our age, the Thin Place quest has morphed into a challenge to evolve beyond the confines of our own physiology; through human ingenuity and invention, we reach places not meant to accommod...

Marcouyeux, Aurore; Fleury-Bahi, Ghozlane

2011-01-01

Studies on place identity show positive relationships between the evaluation of a place and mechanisms involved in place identification. However, individuals also identify with places of low social prestige (places that bear a negative social image). Few authors investigate the nature of place identity processes in this case. The goal of this…

Simulated shift work in rats perturbs multiscale regulation of locomotor activity

Motor activity possesses a multiscale regulation that is characterized by fractal activity fluctuations with similar structure across a wide range of timescales spanning minutes to hours. Fractal activity patterns are disturbed in animals after ablating the master circadian pacemaker (suprachiasmatic nucleus, SCN) and in humans with SCN dysfunction as occurs with aging and in dementia, suggesting the crucial role of the circadian system in the multiscale activity regulation. We hypothesized that the normal synchronization between behavioural cycles and the SCN-generated circadian rhythms is required for multiscale activity regulation. To test the hypothesis, we studied activity fluctuations of rats in a simulated shift work protocol that was designed to force animals to be active during the habitual resting phase of the circadian/daily cycle. We found that these animals had gradually decreased mean activity level and reduced 24-h activity rhythm amplitude, indicating disturbed circadian and behavioural cycles. Moreover, these animals had disrupted fractal activity patterns as characterized by more random activity fluctuations at multiple timescales from 4 to 12 h. Intriguingly, these activity disturbances exacerbated when the shift work schedule lasted longer and persisted even in the normal days (without forced activity) following the shift work. The disrupted circadian and fractal patterns resemble those of SCN-lesioned animals and of human patients with dementia, suggesting a detrimental impact of shift work on multiscale activity regulation.

Januario, Leticia Bergamin; Madeleine, Pascal; Cid, Marina Machado; Samani, Afshin; Oliveira, Ana Beatriz

2018-01-01

This study investigated the acute effects of changing the work pace and implementing two pause types during an assembly task. Eighteen healthy women performed a simulated task in four different conditions: 1) slow or 2) fast work pace with 3) passive or 4) active pauses every two minutes. The root mean square (RMS) and exposure variation analysis (EVA) from the trapezius and serratus anterior muscles, as well as the rate of perceived exertion (RPE) from the neck-shoulder region, were observed. Decreased RMS and RPE as well as more variable muscle activity (EVA) were observed in the slow work pace compared with the fast one. The pause types had a limited effect, but active pauses resulted in increased RMS of the clavicular trapezius. The findings revealed the importance of work pace in the reduction of perceived exertion and promotion of variation in muscle activation during assembly tasks. However, the pause types had no important effect on the evaluated outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

Purpose – Cities increasingly compete with each other for attracting tourists, investors, companies, or residents. Marketers therefore focus on establishing the city as a brand, disregarding that the perception and knowledge of a city differ dramatically between the target audiences. Hence, place...... branding should emphasize much more the perceptions of the different target groups and develop strategies for advanced place brand management. The aim of this paper is to assess the important discrepancies between the city brand perceptions of different target groups with the help of network analysis......-ended-question survey with 334 participants. Findings – Structural differences for the city brand perceptions of two different target groups and the differences between perceptions of an external and internal target group are highlighted. The results and the managerial implications for place marketers are discussed...

Full Text Available Karen Grimmer, Debra Kay, Jan Foot, Khushnum PastakiaInternational Center for Allied Health Evidence, Sansom Institute, City East Campus, University of South Australia, Adelaide, SA, AustraliaBackground: Supporting older people’s choices to live safely and independently in the community (age-in-place can maximize their quality of life and minimize unnecessary hospitalizations and residential care placement. Little is known of the views of older people about the aging-in-place process, and how they approach and prioritize the support they require to live in the community accommodation of their choice.Purpose: To explore and synthesize the experiences and perspectives of older people planning for and experiencing aging-in-place.Methods: Two purposively sampled groups of community-dwelling people aged 65+ years were recruited for individual interviews or focus groups. The interviews were semistructured, audio-recorded, and transcribed. Themes were identified by three researchers working independently, then in consort, using a qualitative thematic analysis approach.Results: Forty-two participants provided a range of insights about, and strategies for, aging-in-place. Thematic saturation was reached before the final interviews. We identified personal characteristics (resilience, adaptability, and independence and key elements of successful aging-in-place, summarized in the acronym HIPFACTS: health, information, practical assistance, finance, activity (physical and mental, company (family, friends, neighbors, pets, transport, and safety.Discussion: This paper presents rich, and rarely heard, older people’s views about how they and their peers perceive, characterize, and address changes in their capacity to live independently and safely in the community. Participants identified relatively simple, low-cost, and effective supports to enable them to adapt to change, while retaining independence and resilience. The findings highlighted how successful

[Myocardial infarction and stress at work place and in the family: 10-year risk of development in an open population of 2564 year old men (epidemiological study in a framework of the WHO program MONICA-PSYCHOSOCIAL)].

With the aim of assessment of 10 year risk of myocardial infarction (MI) development in men in dependence on stress at work place and in the family in a framework of the WHO program "MONICA-PSYCHOSOCIAL" we examined random representative sample of men (n=657) aged 25-64 years inhabitants of one of districts in Novosibirsk. During 10 years (1994-2004) we registered all cases of MI. For assessment of relative risk of MI development we used COX proportional regression model. Among men with first MI 47.4% had high level of stress in the family and 57.9% were subjected to stress at work place. Five and 10 year risk of MI in men with high test levels of stress at home and work place was 2-5 times greater than in those without. Among men subjected to stress in the family MI risk was the highest at age 55-64 years, while permanent stressful situations at work place were more common in age group 45-54 years. Among men with high levels of stress in the family and at work place higher rate of MI development was observed in widowers, divorced men with incomplete high or elementary education, heavy or moderate manual labor workers, and pensioners. The results indicate that critical life events as well as chronic stressful influences increase risk of MI among men aged 25-64 years. The group of greatest risk - middle and old age persons who are less protected against social, political and economical disbalance in the society.

Simulation of unexpected events in using controlled working time

International Nuclear Information System (INIS)

Ruzicka, F.; Kindler, E.

1987-01-01

The RHYTHMS data base is described for random and rhythmic processes, constructed using the SIMULA programming language. An example is shown of its application in the simulation of accidents in discharging radioactive wastes from a bituminization line in a nuclear power plant. The radioactive waste is embedded in bitumen and shipped in unsealed drums. Normal operation envisages such processing of a certain number of drums during one shift. However, an accident can happen whose elimination takes a certain time. The possibility is also considered of personnel exposure and the necessity of replacing the exposed personnel. The selection of the correct solution is then given by the capability of removing all drums and by the determination of the number of work teams that have to be employed for the removal. Object-oriented programming was applied in the solution of the base. (J.B.). 3 refs

The sea: place of ultimate freedom? Ethnographic reflection on in-between places and practices

Directory of Open Access Journals (Sweden)

Nataša Rogelja

2015-09-01

Full Text Available As a result of the rapid development of navigation and communication technology, boat building technology, popularity of travel and the sea, increased living standards, mobile work opportunities, as well as recessions and disillusionment with the nation-state system and postindustrial economy, a constantly increasing number of people adopt mobility on the sea as a way of life. The paper explores the connection between sea imaginaries and maritime lifestyle migration, discussing the process by which sea imaginaries are translated into practice but also how the physical maritime environment influences the experience of lifestyle migrants. In doing so, the concept of liminality, as previously tailored to the lifestyle migration literature and initially introduced by Arnold Van Gennep and Victor Turner, will be put in a dialogue with the ethnographic material. First, the paper explains the theoretical foundations of lifestyle migration, emphasizing the relation between the social construction of places and choices of lifestyle migrants, while also introducing the debate on liminality; second, it discusses the importance of these cultural dimensions in the specific ethnographic setting among Westerners in the Mediterranean who live, travel and work on sailing boats. Finally, the sea images, the maritime environment and details from individualized biographies will be put in a dialogue with each other in order to discuss in-between practices and places.

This work is part of a joint project to built a computational tool for power plant simulation, dealing specifically with the reaction chamber (place of the boiler where the fuel is burned). In order to describe the conversion of chemical energy to thermal energy, an one dimensional pseudo-homogeneous mathematical model, with variable physical properties, and based on mass and energy balances, was developed. The equations were implemented in the gPROMS simulator and the model parameters were estimated using the module gEST of this software, with experimental data from a large-scale coal-fired utility boiler and kinetic data from the open literature. The results showed that the model predicts the composition of the outlet combustion gas satisfactorily. (author)

People and Places Forum Workshop Report | Science ...

Science.gov (United States)

In November 2015, the Twin Ports-based People and Places Work Group (PPWG) coordinated a special gathering to bring together researchers and scholars from diverse fields to discuss environment-human research, scholarship and collaboration opportunities. Hosted by the US Environmental Protection Agency (USEPA), the group approached and invited over 150 individuals from eight regional universities. The goals were to learn who was doing or interested in doing applied research on human-environment interactions, who might have students to engage in work, who might partner with the Lake Superior National Estuarine Research Reserve (Reserve), USEPA, University of Minnesota Duluth’s Natural Resource Research Institute (NRRI), Minnesota and Wisconsin Sea Grant Institutes (Sea Grant), and other partnering institutes and who might be interested in ecosystem services work in particular. A pre-gathering survey collected initial information about this community and the adapted, open-space design gathering allowed for even more data collection about potential new colleagues to engage in the work of understanding people and place in our region. This summary reviews some of findings and presents what may be considered the beginning of a network directory to encourage and facilitate interdisciplinary research and collaboration. This report outlines the process to identify and reach out to health, social science, and humanities scholars to participate in environmental research w

Experimental validation of neutron activation simulation of a varian medical linear accelerator.

Morato, S; Juste, B; Miro, R; Verdu, G; Diez, S

2016-08-01

This work presents a Monte Carlo simulation using the last version of MCNP, v. 6.1.1, of a Varian CLinAc emitting a 15MeV photon beam. The main objective of the work is to estimate the photoneutron production and activated products inside the medical linear accelerator head. To that, the Varian LinAc head was modelled in detail using the manufacturer information, and the model was generated with a CAD software and exported as a mesh to be included in the particle transport simulation. The model includes the transport of photoneutrons generated by primary photons and the (n, γ) reactions which can result in activation products. The validation of this study was done using experimental measures. Activation products have been identified by in situ gamma spectroscopy placed at the jaws exit of the LinAc shortly after termination of a high energy photon beam irradiation. Comparison between experimental and simulation results shows good agreement.

Brodie, David A; Andrews, Gavin J; Andrews, Justin P; Thomas, B Gail; Wong, Josephine; Rixon, Lorna

2005-11-01

During the past decade, a distinct body of research has started to investigate the dynamics between nursing and place. However, despite attention being paid to a wide-range of nursing subjects, few studies have engaged with the important topic of labour force recruitment. In this context, this study uses a combined questionnaire (n=650), interview (n=30) and focus group (n=7) survey of London-based students, and investigates the complex mix of experiences and perceptions that result in hospitals having varying degrees of popularity as potential workplaces. The findings suggest experiences and perceptions of institutions-often gained on clinical placements-to be important, particularly relating to feeling valued, the quality of patient care, clinical and educational opportunities and team cohesion. These are often combined with experiences and perceptions of locality, relating to factors such as cost of living, travel considerations and sense of personnel safety. The study demonstrates that place is relevant to employment decision-making on multiple scales from wards to regions. Furthermore, that perceptions of potential workplaces result from engagements with complex mixes of cultural, economic and physical features, many of which are the consequences of management. It is argued that in order to effectively unpack workplaces, geographical research of nursing labour may benefit from researching simultaneously both 'inside' institutions, focusing on their dominant cultures of production and sub-cultures, and 'outside', focusing on their local urban or rural contexts.

Sense of place and place identity: review of neuroscientific evidence.

Science.gov (United States)

Lengen, Charis; Kistemann, Thomas

2012-09-01

The aim of this review is to bring the phenomenological sense of place approach together with current results from neuroscience. We searched in neuroscientific literature for ten dimensions which were beforehand identified to be important in a phenomenological sense of place/place identity model: behaviour, body, emotion, attention, perception, memory, orientation, spirituality, meaning/value and culture/sociality. Neuroscience has identified many neurobiological correlates of phenomenological observations concerning sense of place. The human brain comprises specific and specialised structures and processes to perceive, memorise, link, assess and use spatial information. Specific parts (hippocampus, entorhinal, parahippocampal and parietal cortex), subregions (parahippocampal place area, lingual landmark area), and cells (place cells, grid cells, border cells, head direction cells) have been identified, their specific function could be understood and their interaction traced. Neuroscience has provided evidence that place constitutes a distinct dimension in neuronal processing. This reinforces the phenomenological argumentation of human geography and environmental psychology. Copyright © 2012 Elsevier Ltd. All rights reserved.

High place working vehicles for nickel hydrogen battery powered distribution construction; Nikkeru suiso denchi kudoshiki haiden kojiyo kosho sagyosha

The Tohoku Electric Power Co. Ltd., in combination with the Aichi Corporation, developed a low noise and no-exhaust gas high place working vehicle that uses NiH battery as a power for lifting or falling a bucket and cutting off electric wires. It is the first in the world that the large scaled NiH battery is used in the application field other than used as a running power of an electric automobile. The main characters of the battery may be pointed out as follows. (1) It has the energy density as 2 times as a lead battery, so 2 times of working time may be obtained by the same weight battery. (2) It is maintenance-free (a periodic maintenance is necessary for a lead battery). (3) Reduction of charging efficiency caused by the heat generated during the charging can be prevented by development of a battery cooling system. (4) As the battery is low noise and no exhaust gas, it does not trouble inhabitant anytime. The new type battery has been used in the Mizusawa business office and tested there by the end of 1998.

A group of persons exposed to radiation for professional reasons was monitored in EIR by means of thyroid and urin tests during one year. To determine the incorporation risk at the working-place wipe tests and air filter samples were carried out daily during the same time. The activities determined in the urin vary between 0,3% and 6% of the thyroid depot. The urin measurements are suitable for the manifestation of the incorporation. But to evaluate these the individual iod-excretion-rate must be determined before. The results of the measurements, the measuring devices, and the methods are explained. Incorporation was caused by improper storage of preparations and wastes, insufficient aeration, and imperfect methods. (orig./HP) [de

Characteristics of economic and mathematical simulation of development of working mines

Energy Technology Data Exchange (ETDEWEB)

Gorodnichiy, V G

1979-01-01

Economic and mathematical simulation is promoted by a standard procedure of computations to optimize development of production for the future as the principal method of solution of a problem. However traditional approaches to design of models need refinement which take into account the dynamic nature of a coal mine. First, the characteristics of the elements in subsystems change; second, as time passes the very structure of the system is transformed. Consequently, these processes should be reflected in the simulation in a corresponding manner. In practical terms this is expressed in the formation of files of forecast information used in computations according to a model and also in development of procedures of transformation of the model structure with a change of the structure of the subject mine with time. Let us note that the invariability of the state of the principal elements of the technological scheme of a mine with time is the necessary condition of acceptability of a model of the evolution type which is most common. For working mines the freedom of selecting solutions is considerably less than the analogous one in design.

Several countries restrict individuals with type 1 diabetes mellitus (T1DM) from skydiving because of concerns over possible alterations in consciousness. To our knowledge, glucose levels and working memory in individuals with T1DM during skydiving have not been assessed earlier. The objective of this study was to investigate changes in glucose levels and working memory in selected subjects with T1DM compared with control subjects without diabetes mellitus (DM) during ambient air pressure changes as those anticipated during standard skydiving. Six subjects with T1DM and six controls were included. Using a hypobaric chamber, the ambient air pressure was changed to simulate a standard skydive from 4,000 m (13,000 feet) above mean sea level. The procedure was repeated six times to mimic a day of skydiving activity with a median of 8.7 h/day (5(th), 95(th) percentile: 8.1, 9.8 h). All subjects carried a continuous glucose monitor (CGM). Capillary glucose tests were taken in order to calibrate the CGM. Hemoglobin oxygen saturation, heart rate, and working memory, evaluated through digit span, were monitored regularly. No subject experienced documented symptomatic hypoglycemia with impaired working memory during the simulations. One asymptomatic hypoglycemia episode with a plasma glucose level of glucose levels. Interstitial glucose levels of memory between the T1DM patients and the controls. This study of interstitial glucose levels and working memory could not show the activity-specific risk factor (i.e., repetitive rapid-onset hypobaric hypoxia exposures) to be a greater safety concern for selected subjects with T1DM compared with subjects without DM during a simulated day of skydiving. Further studies are needed to clarify the suitability of subjects with T1DM to participate in this air sport.

Evaluation and development of process operators' working practices

International Nuclear Information System (INIS)

Norros, L.

1998-01-01

The practical aim of our research was to enhance the safety of NPP operations through the development of competencies and design of man-machine interfaces, and through contributing to safety management by providing better human reliability assessment methods. A prerequisite for achievements in these issues is understanding of the nature of the work in the NPP. We have focused on the comprehension of the control room operators' core task. With the premise of the intentional nature of human activity we have developed a new contextual approach for the analysis of activity in real-life situations. It is called the Contextual Analysis of Working Practices (CAWP). Habit of action is a central concept, and we have proposed a practical way to identify habits of action through the analysis of the actors' ways of taking account of the possibilities and constraints of the situation and of using available resources. We have carried out empirical studies in two nuclear power plants and executed four series of simulator experiments. This has taken place in close co-operation with the simulator trainers and experts of the plants, and nearly all control room crews of these plants have been involved. The central result of this work is the development of the CAWP methodology. With the help of it we have identified differences in the NPP operators' working practices that seem to have relevance for the adequacy of process control. We have also found indications of the significance of working practices for a situationally adaptive use of information aids in the control room, which ought to be verified later. Our research method has been adapted for a routinely used simulator training method. Moreover, the methodology has been applied as a tool in the validation of control room information aids, and incorporated into a new dynamic human reliability method (not discussed here). (orig.)

Simulator training is a key component in achieving and preserving on the long term the necessary expertise of plant personnel also required by the authorities. In this way, it makes an important contribution to the safe operation of nuclear power plants. Simulators are a component in the training of operating personnel of nuclear power plants which allows nuclear power plant operators to be prepared in a focused and practice-oriented way for their activity in everyday plant operation and for possible accident simulation. The simulator center is supported by 5 nuclear power plant operators: the German E.ON Kernkraft GmbH, RWE Power AG, EnBW Kraftwerke AG, and Vattenfall Europe Nuclear Energy GmbH companies as well as the Netherlands N.V. Electriciteits-Produktiemaatschappij Zuid-Nederland. They established a joint enterprise in Essen which performs in one central place the duty of simulator training incumbent upon all nuclear power plants. (orig.)

Mikkelsen, Jacob Bjerre; Lange, Ida Sofie Gøtzsche

from the 'Everyday World'. Within mobilities studies, research has focused on different aspects and consequences of the post-oil society (see Dennis & Urry 2009, Urry 2013). This paper discusses the conception of place within the enclosed 'Oil World' with point of departure in relocation...... and redefinition of oil rigs from an urban design perspective. The paper constitutes a theoretical basis for future design scenarios - exemplified through visionary urban design proposals for a specific site in the city of Esbjerg, Denmark. Relocating rigs to an urban context initiates discussions of conception...... of 'Place' questioning the fixity of 'Place' (Jensen 2010). Scoped through a relational sense of place (Massey 1993) and the potential of exploring new relations between places (Burns & Kahn 2005), the paper challenges the notion of 'Place as God' (Hvattum 2010).

Monte Carlo simulation of muon-induced background of an anti-Compton gamma-ray spectrometer placed in a surface and underground laboratory

CERN Document Server

Vojtyla, P

2005-01-01

Simulations of cosmic ray muon induced background of an HPGe detector placed inside an anti-Compton shield on the surface and in shallow underground is described. Investigation of several model set-ups revealed some trends useful for design of low-level gamma-ray spectrometers. It has been found that background spectrum of an HPGe detector can be scaled down with the shielding depth. No important difference is observed when the same set-up of the anti-Compton spectrometer is positioned horizontally or vertically. A cosmic-muon rejection factor of at least 40 (at around 1 MeV) can be reached when the anti-Compton suppression is operational. The cosmicmuon background can be reduced to such a level that other background components prevail, like those from the residual contamination of the detector and shield materials and/or from radon, especially for the underground facilities.

The importance of simulation in nursing education

Directory of Open Access Journals (Sweden)

Evrim Eyikara

2017-01-01

Full Text Available Nursing education involves a practice-oriented curriculum in which emphasis is placed on both theoretical knowledge and psychomotor skills. In skill-based education, where learning through practice occupies a central role, it is important to ensure the integration of theoretical knowledge into practice. In this context, simulations represent an innovative teaching method that stimulates a number of senses at the same time among learners. Simulation is a method which can be designed to reflect real-life conditions, and which provides the opportunity to work in contexts that are closer and more representative of real settings. Depending on the clinical situation or scenario; the simulation method will involve a student or a group of students performing a number of patient care activities on a manikin, player or standardized patient. The simulation method allows students to repeatedly practice their clinical skills until they develop a sense of proficiency; to learn at their own pace; and to freely make mistakes. Simulations is an educational process that can replicate clinical practices in a safe environment. Nursing students who take part in education programs involving simulations perform less medical mistakes in clinical settings, and are able to better develop their critical thinking and clinical decision-making skills. For these reasons, we recommend that simulations, which represent an interactive learning method, are rendered more common in institutions providing nursing education.

Telecommuting's differential impact on work-family conflict: is there no place like home?

Science.gov (United States)

Golden, Timothy D; Veiga, John F; Simsek, Zeki

2006-11-01

The literature on the impact of telecommuting on work-family conflict has been equivocal, asserting that telecommuting enhances work-life balance and reduces conflict, or countering that it increases conflict as more time and emotional energy are allocated to family. Surveying 454 professional-level employees who split their work time between an office and home, the authors examined how extensively working in this mode impacts work-to-family conflict and family-to-work conflict, as well as the contextual impact of job autonomy, scheduling flexibility, and household size. As hypothesized, the findings suggest that telecommuting has a differential impact on work-family conflict, such that the more extensively individuals work in this mode, the lower their work-to-family conflict, but the higher their family-to-work conflict. Additionally, job autonomy and scheduling flexibility were found to positively moderate telecommuting's impact on work-to-family conflict, but household size was found to negatively moderate telecommuting's impact on family-to-work conflict, suggesting that contextual factors may be domain specific.

Wang, Zhuangzhuang; Yang, Jie; Liu, Pingyi; Zhao, Junpeng

2018-02-01

Hourglass worm is extensively used in industry due to its characteristic of heavy-load and a large reduction ratio. Varying sizes of unbalanced mass distribution appeared in the design of a single head worm. With machines developing towards higher speed and precision, the vibration and shock caused by the unbalanced mass distribution of rotating parts must be considered. Therefore, the balance grade of these parts must meet higher requirements. A method based on theoretical analysis and SolidWorks motion software simulation is presented in this paper; the virtual dynamic balance simulation test of the hourglass worm was carried out during the design of the product, so as to ensure that the hourglass worm meet the requirements of dynamic balance in the design process. This can effectively support the structural design of the hourglass worm and provide a way of thinking and designing the same type of products.

2011-09-07

OBJECTIVE: To report on the perceptions of a group of orthopaedic trainees and trainers on perceived effects of the proposed introduction of European Working Time Directive (EWTD) restrictions into Ireland and on the use of simulators in training orthopaedic skills. METHODS: A structured questionnaire was developed to evaluate the opinions of a group of orthopaedic surgeons and trainees at the annual national orthopaedic conference. RESULTS: There were 44 participants [12 consultants, 32 trainees (15 specialist registrars, 8 registrars, 9 senior house officers)]. Seventy-five percent of participants felt that both the quality of patient care and training would be negatively affected. A higher proportion of consultants than trainees felt that quality of life would be affected. A high proportion of participants (81.8%) had used a simulator or model to learn a surgical skill and 100% would consider using them again. CONCLUSIONS: While we wait for the full introduction of the EWTD hours the perception is that both quality of patient care and training will be affected. Models and simulators are well perceived as a method of training.

Designing Place-Based Interventions for Sustainability and Replicability: The Case of GO! Austin/VAMOS! Austin.

Hussaini, Aliya; Pulido, Carmen Llanes; Basu, Semonti; Ranjit, Nalini

2018-01-01

Place-based health efforts account for the role of the community environment in shaping decisions and circumstances that affect population well-being. Such efforts, rooted as they are in the theory that health is socially determined, mobilize resources for health promotion that are not typically used, and offer a more informed and robust way of promoting health outcomes within a community. Common criticisms of place-based work include the difficulty of replication , since engagement is so specific to a place, and limited sustainability of the work, in the absence of continued institutional structures, both within the community and supporting structures outside the community, to keep these initiatives resilient. This paper describes a place-based initiative, GO! Austin/VAMOS! Austin (GAVA), which was designed to harness the strengths of place-based work-namely, its specificity to place and community. From the start, the project was designed to balance this specificity with a focus on developing and utilizing a standardized set of evidence-informed implementation and evaluation approaches and tools that were flexible enough to be modified for specific settings. This was accompanied by an emphasis on leadership and capacity building within resident leaders, which provided for informed intervention and demand building capacity, but also for longevity as partners, philanthropic, and otherwise, moved in and out of the work.

Sullivan, George F. III

2013-01-01

The iterative design process is one of many strategies used in new product development. Top-down development strategies, like waterfall development, place a heavy emphasis on planning and simulation. The iterative process, on the other hand, is better suited to the management of small to medium scale projects. Over the past four months, I have worked with engineers at Johnson Space Center on a multitude of electronics projects. By describing the work I have done these last few months, analyzing the factors that have driven design decisions, and examining the testing and verification process, I will demonstrate that iterative design is the obvious choice for research and development projects.

This article, based on a qualitative methodology that includes in-depth interviews with owners of 73 centers dedicated to the sexual commerce in nine Mexican States, examines the prostitution of minors in these places towards the appreciations of the pimps, and concludes that the spread of a culture of bribery in the prostitution industry leads to the solidification of networks of complicity between the police and pimps leading to the prostitution of minors.

Vermont Yankee simulator BOP model upgrade

International Nuclear Information System (INIS)

Alejandro, R.; Udbinac, M.J.

2006-01-01

The Vermont Yankee simulator has undergone significant changes in the 20 years since the original order was placed. After the move from the original Unix to MS Windows environment, and upgrade to the latest version of SimPort, now called MASTER, the platform was set for an overhaul and replacement of major plant system models. Over a period of a few months, the VY simulator team, in partnership with WSC engineers, replaced outdated legacy models of the main steam, condenser, condensate, circulating water, feedwater and feedwater heaters, and main turbine and auxiliaries. The timing was ideal, as the plant was undergoing a power up-rate, so the opportunity was taken to replace the legacy models with industry-leading, true on-line object oriented graphical models. Due to the efficiency of design and ease of use of the MASTER tools, VY staff performed the majority of the modeling work themselves with great success, with only occasional assistance from WSC, in a relatively short time-period, despite having to maintain all of their 'regular' simulator maintenance responsibilities. This paper will provide a more detailed view of the VY simulator, including how it is used and how it has benefited from the enhancements and upgrades implemented during the project. (author)

Ensemble place codes in hippocampus: CA1, CA3, and dentate gyrus place cells have multiple place fields in large environments.

Directory of Open Access Journals (Sweden)

Eunhye Park

Full Text Available Previously we reported that the hippocampus place code must be an ensemble code because place cells in the CA1 region of hippocampus have multiple place fields in a more natural, larger-than-standard enclosure with stairs that permitted movements in 3-D. Here, we further investigated the nature of hippocampal place codes by characterizing the spatial firing properties of place cells in the CA1, CA3, and dentate gyrus (DG hippocampal subdivisions as rats foraged in a standard 76-cm cylinder as well as a larger-than-standard box (1.8 m×1.4 m that did not have stairs or any internal structure to permit movements in 3-D. The rats were trained to forage continuously for 1 hour using computer-controlled food delivery. We confirmed that most place cells have single place fields in the standard cylinder and that the positional firing pattern remapped between the cylinder and the large enclosure. Importantly, place cells in the CA1, CA3 and DG areas all characteristically had multiple place fields that were irregularly spaced, as we had reported previously for CA1. We conclude that multiple place fields are a fundamental characteristic of hippocampal place cells that simplifies to a single field in sufficiently small spaces. An ensemble place code is compatible with these observations, which contradict any dedicated coding scheme.

An Emotional Engine for Behavior Simulators

Directory of Open Access Journals (Sweden)

Santiago García Carbajal

2015-06-01

Full Text Available Interpreting, modeling and representing emotions is a key feature of new generation games. This paper describes the first version of the Emotional Engine we have developed as a component of more complex behavior simulators. The purpose of this module is to manage the state and behavior of the characters present in a scene while they interact with a human user. We use preexistent language recognition libraries like Windows™ Speech API, and Kinect™ devices to communicate real humans with artificial characters participating in a virtual scene. The Emotional Engine works upon numeric variables extracted from such devices and calculated after some natural language interpretation process. It then produces numerical results that lead the behavior, modify both the verbal and body language of the characters, and influence the general evolution of the scene that takes place inside the simulator. This paper presents the system architecture and discusses some key components, such as the Language Interpretation and the Body Language Interpreter modules.

Associations between eating occasions and places of consumption among adults.

Liu, Jodi L; Han, Bing; Cohen, Deborah A

2015-04-01

The objective of this study was to determine whether places of consumption are associated with types of eating occasions. Data on dietary behaviors of 226 adults in five U.S. cities were collected in food diaries for one week. Types of eating occasions and places of consumption were recorded. Eating occasions were defined as occurrences of meal, snack, beverage, and non-fruit dessert consumption. Nearly one-third of eating occasions occurred at non-designated eating places. Repeated measure generalized linear models were used to assess the associations between types of eating occasions and places where food was consumed. Snacking on low-nutrient foods were more likely to occur in non-designated eating places. Snacking was more likely at work than at home, and sugar sweetened beverage consumption was more likely at food service outlets than at home. The finding that places of consumption were associated with different types of eating occasions suggests that contextual characteristics of a place are important in individual eating behaviors. Policies and programs aiming to promote healthy eating should leverage contextual characteristics of eating environments. Copyright © 2014 Elsevier Ltd. All rights reserved.

Prediction of Tensile Behavior of UHSFRC Considering the Flow Field in the Placing Dominated by Shear Flow.

Science.gov (United States)

Moon, Joon-Shik; Kang, Su-Tae

2018-01-26

Considering the case of fabricating a UHSFRC (ultra-high strength fiber-reinforced concrete) beam with the method of one end placing and self-flowing to the other end, it was intended to simulate the variation of the fiber orientation distribution according to the flow distance and the variation of the resultant tensile behaviors. Then the validity of the simulation approach was shown by comparing the simulated results with experimental ones. A three-point bending test with a notched beam was adopted for the experiment and a finite element analysis was performed to obtain the simulated results for the bending test considering the flow-dependent tensile behavior of the UHSFRC. From the simulation for the fiber orientation distribution according to the flow distance, it could be found that the major change in the fiber orientation distribution took place within a short flow distance and most of the fibers became nearly aligned to the flow direction. After some flow distance, there was a not-so-remarkable variation in the fiber orientation distribution that could influence the tensile behavior of the composite. For this flow region, the consistent flexural test results, regardless of flow distance, demonstrate the reliability of the simulation.

The objective of the present work is to give to know the most important characteristics in the Russian nuclear reactor of pressurized light water VVER-1000, doing emphasis in the differences that has with the western equivalent the reactor PWR in the design and the safety systems. Therefore, a description of the computerized simulation of the reactor VVER-1000 developed by the company Eniko TSO that the International Atomic of Energy Agency distributes to the states members with academic purposes will take place. The simulator includes mathematical models that represent to the essential systems in the real nuclear power plant, for what is possible to reproduce common faults and transitory characteristic of the nuclear industry with a behavior sufficiently attached to the reality. In this work is analyzed the response of the system before a turbine shot. After the accident in the nuclear power plant of Three Mile Island (US) they have been carried out improvements in the design of the reactor PWR and their safety systems. To know the reach and the limitations of the program, the events that gave place to this accident will be reproduced in the simulator VVER-1000. With base to the results of the simulation we will conclude that so reliable is the response of the safety system of this reactor. (Author)

The ALLAN.Simulation code was developed by the R and D direction of Gaz de France (GdF) company with the support of CISI and Dassault Data Services companies. Its aim is to provide a modeling tool for the design and operation of complex technical systems. It uses a `boxes and ropes` representation (non-oriented multi-variable bloc-schemes) which allows the re-use of all or part of previous models or analyses already developed and recorded. The third meeting of the non-GdF users of the ALLAN.Simulation code took place at Sophia Antipolis (France) on May 27, 1994. Several studies performed with ALLAN.Simulation were presented and dealt with: a thermohydraulic loop, an alternator for automobile, and the hydration of cements. This report is a compilation of the transparencies relative to these three studies. A last part is devoted the presentation of the possible links between different existing simulation codes: ALLAN, BASILE, MAPLE, NEPTUNIX. (J.S.)

Space, place and body: temporary coalitions, nodes in a network

Directory of Open Access Journals (Sweden)

Kerith Power

2012-12-01

Full Text Available The articles in this collection share a concern for place, space and bodies as frameworks for thinking about and conducting educational research. The authors range in experience from senior academics, independent educators, beginning and emerging new researchers spanning a range of educational sectors. The articles originate from connections forged within and between Australia and northern countries with visits back and forth between 2004 and 2010. Some of the writers have met each other in these travels and others have not. All have encountered and participated in some way in the work of the space place and body research group, which originated in 2007 as a named research ‘node’ at Monash University.   The space place and body group formed as a result of a process designed to re-imagine research in the Faculty of Education at Monash University in order to address ‘the big questions of our time’. As a leading global university with campuses in Asia and Europe as well as several in Australia, the Dean of the Faculty cited recent evidence that the field of educational research had become too narrowly focused and that new approaches were needed to enliven the field and move it forward. Individualistic research was no longer supported and groups were formed organically around coalitions of interest. The purpose of the space place and body group was to come together to generate new conceptual, theoretical and methodological resources within the core concepts of space, place and body by collaborating across our differences. In the early phase of our development we focused on linked identity (ontological and knowledge (epistemological work, at the intersection of postcolonial and poststructural approaches to place in educational research. A specific interest in alternative and creative methodologies emerged from these onto-epistemological activities.   As part of our process we initiated temporary definitions of space, place and body, to

Continuing bonds and place.

Where do people feel closest to those they have lost? This article explores how continuing bonds with a deceased person can be rooted in a particular place or places. Some conceptual resources are sketched, namely continuing bonds, place attachment, ancestral places, home, reminder theory, and loss of place. The authors use these concepts to analyze interview material with seven Swedes and five Britons who often thought warmly of the deceased as residing in a particular place and often performing characteristic actions. The destruction of such a place, by contrast, could create a troubling, haunting absence, complicating the deceased's absent-presence.

Experiencing contemporary cafés and changes in the characteristic of third places

Science.gov (United States)

Nurliani Lukito, Yulia; Puspita Xenia, Anneli

2018-03-01

The fast development of modern cafés in the city is related to the creation of urban public space. The idea of a café as a public space is not new but how a café creates a convenience public space for people with different backgrounds is still an interesting phenomenon. Modern cafés like Starbucks and Crematology – famously known as a sign of globalization and consumerism – have spread to both campus and working areas. Oldenburg distinguishes “third places” as the public places on neutral ground where people can gather, interact and enjoy the surroundings (Oldenburg, 1991). In contrast to first places (home) and second places (work), third places serve as places for social interaction and often considered anchors of community life. This paper discusses how modern cafés in UI campus and working areas actually show modifications for the characteristic of Oldenburg’s third places. The study tries to connect how modern cafés appear to be a remarkably social space where some of the barriers to social interaction declines and in the end will promote social attachment. The argument in this paper is that modern cafés offer a comforting and neutral, yet generic enough to lend itself to whatever meaning people want to use it. The method conducted is through direct observations and qualitative analyses of the Starbucks café located at Universitas Indonesia Depok campus and the Crematology café near Sudirman, Jakarta, as the case studies.

Simulating Optical Correlation on a Digital Image Processing

Denning, Bryan

1998-04-01

Optical Correlation is a useful tool for recognizing objects in video scenes. In this paper, we explore the characteristics of a composite filter known as the equal correlation peak synthetic discriminant function (ECP SDF). Although the ECP SDF is commonly used in coherent optical correlation systems, the authors simulated the operation of a correlator using an EPIX frame grabber/image processor board to complete this work. Issues pertaining to simulating correlation using an EPIX board will be discussed. Additionally, the ability of the ECP SDF to detect objects that have been subjected to inplane rotation and small scale changes will be addressed by correlating filters against true-class objects placed randomly within a scene. To test the robustness of the filters, the results of correlating the filter against false-class objects that closely resemble the true class will also be presented.

Bright-light exposure during daytime sleeping affects nocturnal melatonin secretion after simulated night work.

The guidelines for night and shift workers recommend that after night work, they should sleep in a dark environment during the daytime. However, staying in a dark environment during the daytime reduces nocturnal melatonin secretion and delays its onset. Daytime bright-light exposure after night work is important for melatonin synthesis the subsequent night and for maintaining the circadian rhythms. However, it is not clear whether daytime sleeping after night work should be in a dim- or a bright-light environment for maintaining melatonin secretion. The aim of this study, therefore, was to evaluate the effect of bright-light exposure during daytime sleeping on nocturnal melatonin secretion after simulated night work. Twelve healthy male subjects, aged 24.8 ± 4.6 (mean ± SD), participated in 3-day sessions under two experimental conditions, bright light or dim light, in a random order. On the first day, the subjects entered the experimental room at 16:00 and saliva samples were collected every hour between 18:00 and 00:00 under dim-light conditions. Between 00:00 and 08:00, they participated in tasks that simulated night work. At 10:00 the next morning, they slept for 6 hours under either a bright-light condition (>3000 lx) or a dim-light condition (night work were compared between the light conditions using paired t-tests. The ANOVA results indicated a significant interaction (light condition and3 day) (p = .006). Post hoc tests indicated that in the dim-light condition, the melatonin concentration was significantly lower on the second day than on the first day (p = .046); however, in the bright-light condition, there was no significant difference in the melatonin concentration between the days (p = .560). There was a significant difference in ΔDLMO between the conditions (p = .015): DLMO after sleeping was advanced by 11.1 ± 17.4 min under bright-light conditions but delayed for 7.2 ± 13.6 min after sleeping under dim-light conditions.

Higgins, Anthony K.

2010-12-01

Full Text Available The first recorded landing by Europeans on the coast of northern East Greenland (north of 69°N was that of William Scoresby Jr., a British whaler, in 1822. This volume includes a chronological summary of the pioneer 19th century exploration voyages made by British, Danish, Norwegian, Swedish, French and German expeditions – all of whom reported that the region had previously been occupied by the Inuit or Eskimo; also included are brief outlines of the increasing number of government and privately sponsored expeditions throughout the 20th century, whose objectives included cartography, geology, zoology, botany, trapping and the ascent of the highest mountain summits. In 1934 the Place Name Committee for Greenland was established, the tasks of which included a review of all place names hitherto recorded on published maps of Greenland, their formal adoption in danicised form, and the approval or rejection of new name proposals. In northern East Greenland, by far the largest numbers of new place names were those proposed by scientists associated with Lauge Koch’s geological expeditions that lasted from 1926 until 1958. This volume records the location and origin of more than 3000 officially approved place names as well as about 2650 unapproved names.The author’s interest in the exploration history and place names of northern East Greenland started in 1968, when the Geological Survey of Greenland initiated a major five-year geological mapping programme in the Scoresby Sund region. Systematic compilation of names began about 1970, initially with the names given by William Scoresby Jr., and subsequently broadened in scope to include the names proposed by all expeditions to northern East Greenland. The author has participated in 16 summer mapping expeditions with the Survey to northern East Greenland. Publication of this volume represents the culmination of a lifetime working in the Arctic.

Design of simulation-based medical education and advantages and disadvantages of in situ simulation versus off-site simulation.

Simulation-based medical education (SBME) has traditionally been conducted as off-site simulation in simulation centres. Some hospital departments also provide off-site simulation using in-house training room(s) set up for simulation away from the clinical setting, and these activities are called in-house training. In-house training facilities can be part of hospital departments and resemble to some extent simulation centres but often have less technical equipment. In situ simulation, introduced over the past decade, mainly comprises of team-based activities and occurs in patient care units with healthcare professionals in their own working environment. Thus, this intentional blend of simulation and real working environments means that in situ simulation brings simulation to the real working environment and provides training where people work. In situ simulation can be either announced or unannounced, the latter also known as a drill. This article presents and discusses the design of SBME and the advantage and disadvantage of the different simulation settings, such as training in simulation-centres, in-house simulations in hospital departments, announced or unannounced in situ simulations. Non-randomised studies argue that in situ simulation is more effective for educational purposes than other types of simulation settings. Conversely, the few comparison studies that exist, either randomised or retrospective, show that choice of setting does not seem to influence individual or team learning. However, hospital department-based simulations, such as in-house simulation and in situ simulation, lead to a gain in organisational learning. To our knowledge no studies have compared announced and unannounced in situ simulation. The literature suggests some improved organisational learning from unannounced in situ simulation; however, unannounced in situ simulation was also found to be challenging to plan and conduct, and more stressful among participants.

Beginning in 2005, intergranular stress corrosion cracking (IGSCC) of barrel bolts made from cold worked type 316Ti (German Material No. 1.4571 K) was observed in several S/KWU type PWRs. This mechanism was so far less understood for PWR primary conditions. Therefore an extended joint research program was launched by AREVA GmbH and VGB e.V. to clarify the specific conditions which contributed to the observed findings on barrel bolts. In the frame of this research program beneath the evaluation of the operational experience also laboratory tests on the general cracking behavior of cold worked type 316Ti material, which followed the same production line as for barrel bolt manufacturing in the eighties, with different cold work levels covering up to 30 % were performed to determine whether there is a specific susceptibility of cold worked austenitic stainless steel specimens to suffer IGSCC under simulated PWR primary conditions. All these slow strain rate tests on tapered specimens and component specimens came to the results that first, much higher cold work levels than used for the existing barrel bolts are needed for IGSCC initiation. Secondly, additional high active plastic deformation is needed to generate and propagate intergranular cracking. And thirdly, all specimens finally showed ductile fracture at the applied strain rates. (authors)

The paper is dedicated to the mathematical model of slurry wastewater treatment and disposal in a flooded mine working. The goal of the research is to develop and analyze the mathematical model of suspended impurities flow and distribution. Impurity sedimentation model is under consideration. Due to the sediment compaction problem solution domain can be modified. The model allows making a forecast whether volley emission is possible. Numerical simulation results for “Kolchuginskaya” coal mine presented. Impurity concentration diagrams in outflow corresponding to the real full-scale data obtained. Safely operation time mine workings like a wastewater treatment facility are estimated. The carried out calculations demonstrate that the method of industrial wastewater treatment in flooded waste mine workings can be put into practice but it is very important to observe all the processes going on to avoid volley emission of accumulated impurities.

2017-02-12

This study was designed to examine the effects of ambient heat on firefighters' physical task performance, and physiological and perceptual responses when sleep restricted during simulated wildfire conditions. Thirty firefighters were randomly allocated to the sleep restricted ( n = 17, SR; 19 °C, 4-h sleep opportunity) or hot and sleep restricted ( n = 13, HOT + SR; 33 °C, 4-h sleep opportunity) condition. Firefighters performed two days of simulated, intermittent, self-paced work circuits comprising six firefighting tasks. Heart rate, and core temperature were measured continuously. After each task, firefighters reported their rating of perceived exertion and thermal sensation. Effort sensation was also reported after each work circuit. Fluids were consumed ad libitum. Urine volume and urine specific gravity were analysed. Sleep was monitored using polysomnography. There were no differences between the SR and HOT + SR groups in firefighters' physiological responses, hydration status, ratings of perceived exertion, motivation, and four of the six firefighting tasks (charged hose advance, rake, hose rolling, static hose hold). Black out hose and lateral repositioning were adversely affected in the HOT + SR group. Working in hot conditions did not appear to consistently impair firefighters work performance, physiology, and perceptual responses. Future research should determine whether such findings remain true when individual tasks are performed over longer durations.

Variable links within perceived police legitimacy?: fairness and effectiveness across races and places.

Science.gov (United States)

Taylor, Ralph B; Wyant, Brian R; Lockwood, Brian

2015-01-01

This work examines connections between two threads of community residents' perceptions of local police legitimacy, effectiveness and procedural fairness, and how those links depend on race, place, and race/place combinations. Previous works have connected these two threads, but have failed (a) to explore the variability of that connection by race, place, and race/place combinations across communities spanning the urban to suburban to rural continuum or (b) to model mutual influence. An extension of the group position thesis and work on minority views of police practices suggest how these variations might be patterned. Data were derived from a 2003 probability-based sampling survey of household respondents across Pennsylvania (n=1289). Generalized confirmatory factor analysis models built procedural fairness and effectiveness indices for four groups: whites in urban core counties, non-whites in urban core counties, whites in non-urban core counties, and non-whites in non-urban core counties. Non-recursive structural equation models revealed variable impacts of perceived police effectiveness on perceived police fairness and, to a lesser extent, of fairness on effectiveness. Implications for a more structurally and contextually aware understanding of links in police legitimacy models are developed. Copyright © 2014 Elsevier Inc. All rights reserved.

Individuals who work nonstandard schedules, such as rotating or night shifts, are more susceptible to workplace injuries, performance decrements, and reduced productivity. This population is also almost twice as likely to use illicit drugs as individuals working a standard day shift. The purpose of this study was to examine the effects of smoked marijuana on performance, mood, and sleep during simulated shift work. Ten experienced marijuana smokers completed this 23-day, within-participant residential study. They smoked a single marijuana cigarette (0, 1.9, 3.56% Δ 9 -THC) one hour after waking for three consecutive days under two shift conditions: day shift and night shift. Shifts alternated three times during the study, and shift conditions were separated by an 'off' day. When participants smoked placebo cigarettes, psychomotor performance and subjective-effect ratings were altered during the night shift compared to the day shift: performance (e.g., vigilance) and a few subjective ratings were decreased (e.g., "Self-Confident"), whereas other ratings were increased (e.g., "Tired"). Objective and subjective measures of sleep were also disrupted, but to a lesser extent. Marijuana attenuated some performance, mood, and sleep disruptions: participants performed better on vigilance tasks, reported being less miserable and tired and sleep a greater number of minutes. Limited negative effects of marijuana were noted. These data demonstrate that abrupt shift changes produce performance, mood, and sleep decrements during night shift work and that smoked marijuana containing low to moderate Δ 9 -THC concentrations can offset some of these effects in frequent marijuana smokers.

Over sea nuclear power plants have been reported cases of internal contamination by alpha nuclides. In many cases, stations encountered significant alpha contamination when aged/legacy equipment was disturbed or handled. Under normal operating conditions, transuranic radionuclides are contained within the fuel rods and therefore are not a contributor to radioactive contamination within a facility. However, transuranic radionuclides result from the presence of tramp-uranium contamination on the exterior of fuel elements. Fuel failures may develop during operating cycles due to a variety of causes, ranging from manufacturing defects to mechanical or abrasive damage. In case of domestic nuclear power plants, the pressure tube replacements in Wolsong Unit 1 and steam generator replacements in Kori Unit 1 were done. Due to deterioration of equipment in accordance with the long-term operation, the domestic nuclear power plants are expected to improve the facilities and the probability of internal exposure from alpha emitters is increasing. The domestic nuclear power plants are only keeping alpha radionuclides of the effluent from the exterior under constant surveillance. The representative areas of CV are just carried out continuous alpha monitoring in during a unit outage. So far, there is no other case with alpha nuclides analysis. As the domestic nuclear power plants are expected to improve the facilities, it is the time to take proactive measures to deal with internal contamination by alpha emitting radioactive elements. In this paper, the possible risk of internal exposure is based on preliminary experiments on the analysis of alpha emitting radioactive elements at working places in nuclear power plants.

Designing Place-Based Interventions for Sustainability and Replicability: The Case of GO! Austin/VAMOS! Austin

Directory of Open Access Journals (Sweden)

Full Text Available Place-based health efforts account for the role of the community environment in shaping decisions and circumstances that affect population well-being. Such efforts, rooted as they are in the theory that health is socially determined, mobilize resources for health promotion that are not typically used, and offer a more informed and robust way of promoting health outcomes within a community. Common criticisms of place-based work include the difficulty of replication, since engagement is so specific to a place, and limited sustainability of the work, in the absence of continued institutional structures, both within the community and supporting structures outside the community, to keep these initiatives resilient. This paper describes a place-based initiative, GO! Austin/VAMOS! Austin (GAVA, which was designed to harness the strengths of place-based work—namely, its specificity to place and community. From the start, the project was designed to balance this specificity with a focus on developing and utilizing a standardized set of evidence-informed implementation and evaluation approaches and tools that were flexible enough to be modified for specific settings. This was accompanied by an emphasis on leadership and capacity building within resident leaders, which provided for informed intervention and demand building capacity, but also for longevity as partners, philanthropic, and otherwise, moved in and out of the work.

Prediction of Tensile Behavior of UHSFRC Considering the Flow Field in the Placing Dominated by Shear Flow

Directory of Open Access Journals (Sweden)

Joon-Shik Moon

2018-01-01

Full Text Available Considering the case of fabricating a UHSFRC (ultra-high strength fiber-reinforced concrete beam with the method of one end placing and self-flowing to the other end, it was intended to simulate the variation of the fiber orientation distribution according to the flow distance and the variation of the resultant tensile behaviors. Then the validity of the simulation approach was shown by comparing the simulated results with experimental ones. A three-point bending test with a notched beam was adopted for the experiment and a finite element analysis was performed to obtain the simulated results for the bending test considering the flow-dependent tensile behavior of the UHSFRC. From the simulation for the fiber orientation distribution according to the flow distance, it could be found that the major change in the fiber orientation distribution took place within a short flow distance and most of the fibers became nearly aligned to the flow direction. After some flow distance, there was a not-so-remarkable variation in the fiber orientation distribution that could influence the tensile behavior of the composite. For this flow region, the consistent flexural test results, regardless of flow distance, demonstrate the reliability of the simulation.

Full-scale retrieval of simulated buried transuranic waste

International Nuclear Information System (INIS)

Valentich, D.J.

1993-09-01

This report describes the results of a field test conducted to determine the effectiveness of using conventional type construction equipment for the retrieval of buried transuranic (TRU) waste. A cold (nonhazardous and nonradioactive) test pit (1,100 yd 3 volume) was constructed with boxes and drums filled with simulated waste materials, such as metal, plastic, wood, concrete, and sludge. Large objects, including truck beds, tanks, vaults, pipes, and beams, were also placed in the pit. These materials were intended to simulate the type of wastes found in TRU buried waste pits and trenches. A series of commercially available equipment items, such as excavators and tracked loaders outfitted with different end effectors, were used to remove the simulated waste. Work was performed from both the abovegrade and belowgrade positions. During the demonstration, a number of observations, measurements, and analyses were performed to determine which equipment was the most effective in removing the waste. The retrieval rates for the various excavation techniques were recorded. The inherent dust control capabilities of the excavation methods used were observed. The feasibility of teleoperating reading equipment was also addressed

Highlights: • Core exit temperature is used in PWRs as an indication of core heat up. • Modelling guidelines of CET response with system codes. • Modelling of heat transfer processes in the core and UP regions. - Abstract: Core exit temperature (CET) measurements play an important role in the sequence of actions under accidental conditions in pressurized water reactors (PWR). Given the difficulties in placing measurements in the core region, CET readings are used as criterion for the initiation of accident management (AM) procedures because they can indicate a core heat up scenario. However, the CET responses have some limitation in detecting inadequate core cooling and core uncovery simply because the measurement is not placed inside the core. Therefore, it is of main importance in the field of nuclear safety for PWR power plants to assess the capabilities of system codes for simulating the relation between the CET and the peak cladding temperature (PCT). The work presented in this paper intends to address this open question by making use of experimental work at integral test facilities (ITF) where experiments related to the evolution of the CET and the PCT during transient conditions have been carried out. In particular, simulations of two experiments performed at the ROSA/LSTF and PKL facilities are presented. The two experiments are part of a counterpart exercise between the OECD/NEA ROSA-2 and OECD/NEA PKL-2 projects. The simulations are used to derive guidelines in how to correctly reproduce the CET response during a core heat up scenario. Three aspects have been identified to be of main importance: (1) the need for a 3-dimensional representation of the core and Upper Plenum (UP) regions in order to model the heterogeneity of the power zones and axial areas, (2) the detailed representation of the active and passive heat structures, and (3) the use of simulated thermocouples instead of steam temperatures to represent the CET readings.

No Escaping the Rat Race: Simulated Night Shift Work Alters the Time-of-Day Variation in BMAL1 Translational Activity in the Prefrontal Cortex.

Millions of people worldwide work during the night, resulting in disturbed circadian rhythms and sleep loss. This may cause deficits in cognitive functions, impaired alertness and increased risk of errors and accidents. Disturbed circadian rhythmicity resulting from night shift work could impair brain function and cognition through disrupted synthesis of proteins involved in synaptic plasticity and neuronal function. Recently, the circadian transcription factor brain-and-muscle arnt-like protein 1 (BMAL1) has been identified as a promoter of mRNA translation initiation, the most highly regulated step in protein synthesis, through binding to the mRNA "cap". In this study we investigated the effects of simulated shift work on protein synthesis markers. Male rats ( n = 40) were exposed to forced activity, either in their rest phase (simulated night shift work) or in their active phase (simulated day shift work) for 3 days. Following the third work shift, experimental animals and time-matched undisturbed controls were euthanized (rest work at ZT12; active work at ZT0). Tissue lysates from two brain regions (prefrontal cortex, PFC and hippocampus) implicated in cognition and sleep loss, were analyzed with m 7 GTP (cap) pull-down to examine time-of-day variation and effects of simulated shift work on cap-bound protein translation. The results show time-of-day variation of protein synthesis markers in PFC, with increased protein synthesis at ZT12. In the hippocampus there was little difference between ZT0 and ZT12. Active phase work did not induce statistically significant changes in protein synthesis markers at ZT0 compared to time-matched undisturbed controls. Rest work, however, resulted in distinct brain-region specific changes of protein synthesis markers compared to time-matched controls at ZT12. While no changes were observed in the hippocampus, phosphorylation of cap-bound BMAL1 and its regulator S6 kinase beta-1 (S6K1) was significantly reduced in the PFC

The recent recurrences of mega tsunamis in the Asian region have rekindled concern regarding potential tsunamis that could inflict severe damage to affected coastal facilities and communities. The 11 March 2011 Fukushima tsunami that crippled nuclear power plants in Northern Japan has further raised the level of caution. The recent discovery of petroleum reserves in the coastal water surrounding Malaysia further ignites the concern regarding tsunami hazards to petroleum facilities located along affected coasts. Working in a group, federal government agencies seek to understand the dynamics of tsunami and their impacts under the coordination of the Malaysian National Centre for Tsunami Research, Malaysian Meteorological Department. Knowledge regarding the generation, propagation and runup of tsunami would provide the scientific basis to address safety issues. An in-house tsunami simulation models known as TUNA has been developed by the authors to assess tsunami hazards along affected beaches so that mitigation measures could be put in place. Capacity building on tsunami simulation plays a critical role in the development of tsunami resilience. This paper aims to first provide a simple introduction to tsunami simulation towards the achievement of tsunami simulation capacity building. The paper will also present several scenarios of tsunami dangers along affected Malaysia coastal regions via TUNA simulations to highlight tsunami threats. The choice of tsunami generation parameters reflects the concern following the Fukushima tsunami.

Misalignment of the endogenous circadian timing system leads to disruption of physiological rhythms and may contribute to the development of the deleterious health effects associated with night shift work. However, the molecular underpinnings remain to be elucidated. Here, we investigated the effect of a 4-day simulated night shift work protocol on the circadian regulation of the human transcriptome. Repeated blood samples were collected over two 24-hour measurement periods from eight healthy subjects under highly controlled laboratory conditions before and 4 days after a 10-hour delay of their habitual sleep period. RNA was extracted from peripheral blood mononuclear cells to obtain transcriptomic data. Cosinor analysis revealed a marked reduction of significantly rhythmic transcripts in the night shift condition compared with baseline at group and individual levels. Subsequent analysis using a mixed-effects model selection approach indicated that this decrease is mainly due to dampened rhythms rather than to a complete loss of rhythmicity: 73% of transcripts rhythmically expressed at baseline remained rhythmic during the night shift condition with a similar phase relative to habitual bedtimes, but with lower amplitudes. Functional analysis revealed that key biological processes are affected by the night shift protocol, most notably the natural killer cell-mediated immune response and Jun/AP1 and STAT pathways. These results show that 4 days of simulated night shifts leads to a loss in temporal coordination between the human circadian transcriptome and the external environment and impacts biological processes related to the adverse health effects associated to night shift work.

Dynamic simulation for effective workforce management in new product development

2012-10-01

Full Text Available Effective planning and management of workforce for new product development (NPD projects is a great challenge to many organisations, especially in the presence of engineering changes during the product development process. The management objective in effective workforce management is to recruit, develop and deploy the right people at the right place at the right time so as to fulfill organizational objectives. In this paper, we propose a dynamic simulation model to address the workforce management problem in a typical NPD project consisting of design, prototyping, and production phases. We assume that workforce demand is a function of project work remaining and the current available skill pool. System dynamics simulation concepts are used to capture the causality relationships and feedback loops in the workforce system from a systems thinking. The evaluation of system dynamics simulation reveals the dynamic behaviour in NPD workforce management systems and shows how adaptive dynamic recruitment and training decisions can effectively balance the workforce system during the NPD process.

Simulation of obstacles’ effect on industrial robots’ working space using genetic algorithm

Full Text Available The study of robot workspace is an interesting problem since its applications are directly related to industry. However, it involves several mathematical complications; Thus, many of the arising questions are left without a definite answer. With the motivation of industrial demand, the need for finding better answers than the existing ones lasts. The workspace (WS determination of a robot with general structural parameters is a complex problem, which cannot be solved in an explicit way. Closed form solutions are only available in some particular cases. Otherwise, computational algorithms and numerical techniques are used. The task becomes even much more complicated by the presence of obstacles in the robot accessible region. Obstacle presence does not only exclude points from the original WS but it affects the whole robot workspace’s shape and size to the extent that it sometimes divides the working space in two or more separate regions that cannot be linked by the same robot. Much research work in the literature is directed toward path planning in the presence of obstacles without having to determine the robot WS. However, a real situation in industry occurs when the knowledge of the WS is of importance in facility layout. This paper presents an approach for the estimation of a generic open-chain robot in the presence of obstacles with any desired number of prismatic and/or revolute joints of any order. Joints’ axes may have any orientation relative to each other. The robot can be placed in free space or in a work cell consisting of a set of Computer Numerically Controlled (CNC machines and some obstacles.

This study is aimed at validating a driving simulator (DS) for the study of driver behavior in work zones. A validation study requires field data collection. For studies conducted in highway work zones, the availability of safe vantage points for data collection at critical locations can be a significant challenge. A validation framework is therefore proposed in this paper, demonstrated using a fixed-based DS that addresses the issue by using a global positioning system (GPS). The validation of the DS was conducted using objective and subjective evaluations. The objective validation was divided into qualitative and quantitative evaluations. The DS was validated by comparing the results of simulation with the field data, which were collected using a GPS along the highway and video recordings at specific locations in a work zone. The constructed work zone scenario in the DS was subjectively evaluated with 46 participants. The objective evaluation established the absolute and relative validity of the DS. The mean speeds from the DS data showed excellent agreement with the field data. The subjective evaluation indicated realistic driving experience by the participants. The use of GPS showed that continuous data collected along the highway can overcome the challenges of unavailability of safe vantage points especially at critical locations. Further, a validated DS can be used for examining driver behavior in complex situations by replicating realistic scenarios. Copyright © 2014 Elsevier Ltd. All rights reserved.

N-body simulations for coupled scalar-field cosmology

Li Baojiu; Barrow, John D.

2011-01-01

We describe in detail the general methodology and numerical implementation of consistent N-body simulations for coupled-scalar-field models, including background cosmology and the generation of initial conditions (with the different couplings to different matter species taken into account). We perform fully consistent simulations for a class of coupled-scalar-field models with an inverse power-law potential and negative coupling constant, for which the chameleon mechanism does not work. We find that in such cosmological models the scalar-field potential plays a negligible role except in the background expansion, and the fifth force that is produced is proportional to gravity in magnitude, justifying the use of a rescaled gravitational constant G in some earlier N-body simulation works for similar models. We then study the effects of the scalar coupling on the nonlinear matter power spectra and compare with linear perturbation calculations to see the agreement and places where the nonlinear treatment deviates from the linear approximation. We also propose an algorithm to identify gravitationally virialized matter halos, trying to take account of the fact that the virialization itself is also modified by the scalar-field coupling. We use the algorithm to measure the mass function and study the properties of dark-matter halos. We find that the net effect of the scalar coupling helps produce more heavy halos in our simulation boxes and suppresses the inner (but not the outer) density profile of halos compared with the ΛCDM prediction, while the suppression weakens as the coupling between the scalar field and dark-matter particles increases in strength.

“Real” Places in Marguerite Duras’s Wartime Paris

Directory of Open Access Journals (Sweden)

Jennifer Willging

2011-06-01

Full Text Available In the four autobiographical narratives in Marguerite Duras’s La Douleur (1985 The War (1994, over one hundred proper place names appear. While these place names all refer to real places, the relationship between these signifiers and their actual geographical referents is mediated, first by their signifieds—the reader’s mental constructs of the places mentioned—and further by their appearance in a text that necessarily creates its own, non-material world. Yet this essay argues that in this uncharacteristically realist text Duras works hard to create the illusion that the Paris there is in fact Occupied Paris, the real city in which she lived out the experiences recounted in her text. She does this, in large part, by indicating the location of each scene with meticulous precision, thus grounding the stories, quite literally, in a geographically and historically situated reality. While many of these sites are among the best-known, and literal, lieux de mémoire ‘sites of memory’ of the Paris of the Second World War, the mention of more obscure places might appear gratuitous. Yet it is precisely in their gratuity, that such details become essential elements of the forceful effet de réel ‘reality effect’ created in the text.

As climate change impacts are felt around the globe, people are increasingly exposed to changes in weather patterns, wildlife and vegetation, and water and food quality, access and availability in their local regions. These changes can impact human health and well-being in a variety of ways: increased risk of foodborne and waterborne diseases; increased frequency and distribution of vector-borne disease; increased mortality and injury due to extreme weather events and heat waves; increased respiratory and cardiovascular disease due to changes in air quality and increased allergens in the air; and increased susceptibility to mental and emotional health challenges. While climate change is a global phenomenon, the impacts are experienced most acutely in place; as such, a sense of place, place-attachment, and place-based identities are important indicators for climate-related health and adaptation. Representing one of the first qualitative case studies to examine the connections among climate change, a changing sense of place, and health in an Inuit context, this research draws data from a multi-year community-driven case study situated in the Inuit community of Rigolet, Nunatsiavut, Canada. Data informing this paper were drawn from the narrative analysis of 72 in-depth interviews conducted from November 2009 to October 2010, as well as from the descriptive analysis of 112 questionnaires from a survey in October 2010 (95% response rate). The findings illustrated that climate change is negatively affecting feelings of place attachment by disrupting hunting, fishing, foraging, trapping, and traveling, and changing local landscapes-changes which subsequently impact physical, mental, and emotional health and well-being. These results also highlight the need to develop context-specific climate-health planning and adaptation programs, and call for an understanding of place-attachment as a vital indicator of health and well-being and for climate change to be framed as an

To assess the impact of certolizumab pegol (CZP), a novel PEGylated anti-tumor necrosis factor, in combination with methotrexate (MTX) on productivity outside and within the home, and on participation in family, social, and leisure activities in adult patients with rheumatoid arthritis (RA). The efficacy and safety of CZP (200 mg and 400 mg) plus MTX were assessed in 2 phase III, multicenter, double-blind, placebo-controlled trials (Rheumatoid Arthritis Prevention of Structural Damage [RAPID] 1 and RAPID 2). The novel, validated, RA-specific Work Productivity Survey (WPS-RA) was used to assess work place and home productivity. WPS-RA responses were collected at baseline and every 4 weeks until withdrawal/study completion. At baseline, 41.6% and 39.8% of subjects were employed outside the home in RAPID 1 and RAPID 2, respectively. Compared with placebo plus MTX, CZP plus MTX significantly reduced work absenteeism and presenteeism among patients working outside the home. Significant reductions in number of household days lost, household days with productivity reduced by >/=50%, and days lost due to RA for participation in family, social, and leisure activities were reported by patients in active treatment relative to placebo plus MTX. Improvements in all measures were observed with CZP plus MTX as early as week 4, and maintained until the study end (12 months in RAPID 1, 6 months in RAPID 2). Findings were consistent with clinical improvements with CZP plus MTX in both trials. CZP plus MTX improved productivity outside and within the home and resulted in more participation in social activities compared with placebo plus MTX. These observations suggest that considerable indirect cost gains might be achieved with this therapeutic agent in RA.

Full Text Available The article presents a literature review in simulation of grinding processes. It takes into consideration the statistical, energy based, and imitation approaches to simulation of grinding forces. Main stages of interaction between abrasive grains and machined surface are shown. The article describes main approaches to the geometry modeling of forming new surfaces when grinding. The review of approaches to the chip and pile up effect numerical modeling is shown. Advantages and disadvantages of grain-to-surface interaction by means of finite element method and molecular dynamics method are considered. The article points out that it is necessary to take into consideration the system dynamics and its effect on the finished surface. Structure of the complex imitation model of grinding process dynamics for flexible work-pieces with spatial surface geometry is proposed from the literature review. The proposed model of spatial grinding includes the model of work-piece dynamics, model of grinding wheel dynamics, phenomenological model of grinding forces based on 3D geometry modeling algorithm. Model gives the following results for spatial grinding process: vibration of machining part and grinding wheel, machined surface geometry, static deflection of the surface and grinding forces under various cutting conditions.

Full Text Available The author deals with the relationships among ideology, the public and 'third place', or coffeehouses in the broadest sense. While the 'first place' devoted to secrecy or semi secrecy of family life, 'second place' devoted controlled productivity in the sphere of work, 'third places' are spaces on the margins of political and media publics and concealed bourgeois family life. The author stresses that there are very strong historical and social ties in the simultaneous genesis of public opinion and civil liberties, ideology (as a Weltanschauung of the social world that can be altered by human intervention and social and political mobilization, critical public of the private citizens, free individuals (who publicly reasoning and 'third places' as some of the key factors in the onset of generative modern civil society. It emphasizes a strong fit among communication revolution, print media and the role of 'third places' in the development of ideology and critical public. It is noticed that the age of ideology is broader concept than the public - the public opinion, and that it is 18th and 19th century spreading an ideology that is specifically associated with the communication revolution - the emergence and spreading of printing, printing technology, print media and the rapid production of printed materials.

The value of place

This commentary seeks to expand the dialogue on place-based science education presented in Katie Lynn Brkich's article, where the connections fifth grade students make between their formal earth science curriculum and their lived experiences are highlighted. The disconnect between the curriculum the students are offered and their immediate environment is clear, and we are presented with examples of how they strive to make connections between the content and what they are familiar with—namely their surroundings. "Place" is identified as a term with complex meanings and interpretations, even in the scope of place-based science education, and understanding how the term is used in any given scenario is essential to understanding the implications of place-based education. Is place used as a location, locale or a sense of place? To understand "place" is to acknowledge that for the individual, it is highly situational, cultural and personal. It is just such attributes that make place-based education appealing, and potentially powerful, pedagogically on one hand, yet complex for implementation on the other. The argument is posed that place is particularly important in the context of education about the environment, which in its simplest manifestation, connects formal science curriculum to resources that are local and tangible to students. The incorporation of place in such a framework seeks to bridge the gap between formal school science subjects and students' lived experiences, yet acknowledges the tensions that can arise between accommodating place meanings and the desire to acculturate students into the language of the scientific community. The disconnect between guiding policy frameworks and the reality of the Next Generation Science Standards is addressed opening an avenue for further discussion of the importance of socio-cultural frameworks of science learning in an ever increasing era of accountability.

The International Atomic Energy Agency (IAEA) sponsors the development of nuclear reactor simulators for education, or arranges the supply of such simulation programs. Aware of this, the Department of Nuclear Engineering of the Universidad Politecnica de Madrid was provided in 2008 with the Interactive Graphical Simulator of the Spanish nuclear power plant Jose Cabrera, whose operation ceased definitively in 2006. According with the IAEA-TECDOC- 1411, the simulator is a Graphical Simulator, used for training of main control room personnel, technical support engineers, and operations management. This paper presents all the work performed at the Department to turn the simulator into a teaching/learning tool, to be use in the nuclear engineering studies following guidance found in: Shtub, A. Parush, T.T. Hewett 'The use of simulation in learning and teaching' (Int. J. Eng. Educ., 25(2), 2009, pp. 206-208). The experience obtained so far with the use of the simulator has been very successful. The graduate students involved in the development of the projects, practices and documents related with the simulator show a great interest for the work that they are doing making that the laboratory where the simulator is installed to be busy place. Regarding the undergraduate students, the practices in the simulator encourage them to follow the Nuclear Energy studies in the Engineering Schools, what is very rewarding for the Department professors. The simulator has proved to be an optimal tool to transfer the knowledge of the physical phenomena that are involved in the nuclear power plants, from the nuclear reactor to the whole set of systems and equipments on a nuclear power plant. It is also a relevant tool for motivation of the students, and to complete the theoretical lessons. This use of the simulator in the learning-teaching process meats also the criteria recommended for the Bologna adapted studies, as it helps to increase the private hands-on work of the student, and

This work is planned to simulate a scenario in which the same conditions that caused the accident at the Fukushima Daichi nuclear power plant are present, using a simulator of a nuclear power plant with VVER-1000 reactor, a different type of technology to the NPP where the accident occurred, which used BWR reactors. The software where it will take place the simulation was created and distributed by the IAEA for academic purposes, which contains the essential systems that characterize this type of NPP. The simulator has tools for the analysis of the characteristic phenomena of a VVER-1000 reactor in the different systems together and planned training tasks. This makes possible to identify the function of each component and how connects to other systems, thus facilitating the visualization of possible failures and the consequences that they have on the general behavior of the reactor. To program the conditions in the simulator, is necessary to know and synthesize a series of events occurred in Fukushima in 2011 and the realized maneuvers to reduce the effects of the system failures. Being different technologies interpretation of the changes that would suffer the VVER systems in the scenario in question will be developed. The Fukushima accident was characterized by the power loss of regular supply and emergency of the cooling systems which resulted in an increase in reactor temperature and subsequent fusion of their nuclei. Is interesting to reproduce this type of failure in a VVER, and extrapolate the lack of power supply in the systems that comprise, as well as pumping systems for cooling, has a pressure regulating system which involves more variables in the balance of the system.

In robotic surgery, the coordination between the console-side surgeon and bed-side assistant is crucial, more than in standard surgery or laparoscopy where the surgical team works in close contact. Xperience™ Team Trainer (XTT) is a new optional component for the dv-Trainer ® platform and simulates the patient-side working environment. We present preliminary results for face, content, and the workload imposed regarding the use of the XTT virtual reality platform for the psychomotor and communication skills training of the bed-side assistant in robot-assisted surgery. Participants were categorized into "Beginners" and "Experts". They tested a series of exercises (Pick & Place Laparoscopic Demo, Pick & Place 2 and Team Match Board 1) and completed face validity questionnaires. "Experts" assessed content validity on another questionnaire. All the participants completed a NASA Task Load Index questionnaire to assess the workload imposed by XTT. Twenty-one consenting participants were included (12 "Beginners" and 9 "Experts"). XTT was shown to possess face and content validity, as evidenced by the rankings given on the simulator's ease of use and realism parameters and on the simulator's usefulness for training. Eight out of nine "Experts" judged the visualization of metrics after the exercises useful. However, face validity has shown some weaknesses regarding interactions and instruments. Reasonable workload parameters were registered. XTT demonstrated excellent face and content validity with acceptable workload parameters. XTT could become a useful tool for robotic surgery team training.

The aim of this study was to compare the effective shaping time and number of rotations required by an endodontist working with hand and rotary ProTaper instruments to completely shape simulated root canals. Eighty Endo Training Blocks (curved canal shape) were used. Manual preflaring was performed with K-Flexofiles #08-10-12-15-17 and #20 Nitiflex at a working length of 18 mm. Specimens were then randomly assigned to 2 different groups (n = 40); group 1 was shaped by using hand ProTaper and group 2 with ProTaper rotary. The number of rotations made in the canal and the effective time required to achieve complete canal shaping were recorded for each instrument. Differences between groups were analyzed with the nonparametric Mann-Whitney U test (P Hand ProTaper required significantly fewer rotations (P ProTaper, whereas the effective working time to fully shape the simulated canal was significantly higher (P hand ProTaper.

Collective efficacy in a high-fidelity simulation of an airline operations center

Science.gov (United States)

Jinkerson, Shanna

This study investigated the relationships between collective efficacy, teamwork, and team performance. Participants were placed into teams, where they worked together in a high-fidelity simulation of an airline operations center. Each individual was assigned a different role to represent different jobs within an airline (Flight Operations Coordinator, Crew Scheduling, Maintenance, Weather, Flight Scheduling, or Flight Planning.) Participants completed a total of three simulations with an After Action Review between each. Within this setting, both team performance and teamwork behaviors were shown to be positively related to expectations for subsequent performance (collective efficacy). Additionally, teamwork and collective efficacy were not shown to be concomitantly related to subsequent team performance. A chi-square test was used to evaluate existence of performance spirals, and they were not supported. The results of this study were likely impacted by lack of power, as well as a lack of consistency across the three simulations.

Planning of optimal work path for minimizing exposure dose during radiation work in radwaste storage

International Nuclear Information System (INIS)

Kim, Yoon Hyuk; Park, Won Man; Kim, Kyung Soo; Whang, Joo Ho

2005-01-01

Since the safety of nuclear power plant has been becoming a big social issue, the exposure dose of radiation for workers has been one of the important factors concerning the safety problem. The existing calculation methods of radiation dose used in the planning of radiation work assume that dose rate dose not depend on the location within a work space, thus the variation of exposure dose by different work path is not considered. In this study, a modified numerical method was presented to estimate the exposure dose during radiation work in radwaste storage considering the effects of the distance between a worker and sources. And a new numerical algorithm was suggested to search the optimal work path minimizing the exposure dose in pre-defined work space with given radiation sources. Finally, a virtual work simulation program was developed to visualize the exposure dose of radiation during radiation works in radwaste storage and provide the capability of simulation for work planning. As a numerical example, a test radiation work was simulated under given space and two radiation sources, and the suggested optimal work path was compared with three predefined work paths. The optimal work path obtained in the study could reduce the exposure dose for the given test work. Based on the results, the developed numerical method and simulation program could be useful tools in the planning of radiation work

Modeling the transport of chemical warfare agents and simulants in polymeric substrates for reactive decontamination

Pearl, Thomas; Mantooth, Brent; Varady, Mark; Willis, Matthew

2014-03-01

Chemical warfare agent simulants are often used for environmental testing in place of highly toxic agents. This work sets the foundation for modeling decontamination of absorbing polymeric materials with the focus on determining relationships between agents and simulants. The correlations of agents to simulants must consider the three way interactions in the chemical-material-decontaminant system where transport and reaction occur in polymer materials. To this end, diffusion modeling of the subsurface transport of simulants and live chemical warfare agents was conducted for various polymer systems (e.g., paint coatings) with and without reaction pathways with applied decontamination. The models utilized 1D and 2D finite difference diffusion and reaction models to simulate absorption and reaction in the polymers, and subsequent flux of the chemicals out of the polymers. Experimental data including vapor flux measurements and dynamic contact angle measurements were used to determine model input parameters. Through modeling, an understanding of the relationship of simulant to live chemical warfare agent was established, focusing on vapor emission of agents and simulants from materials.

Wolkow, Alexander; Ferguson, Sally A; Vincent, Grace E; Larsen, Brianna; Aisbett, Brad; Main, Luana C

2015-01-01

This study investigated the effect restricted sleep has on wildland firefighters' acute cytokine levels during 3 days and 2 nights of simulated physical wildfire suppression work. Firefighters completed multiple days of physical firefighting work separated by either an 8-h (Control condition; n = 18) or 4-h (Sleep restriction condition; n = 17) sleep opportunity each night. Blood samples were collected 4 times a day (i.e., 06:15, 11:30, 18:15, 21:30) from which plasma cytokine levels (IL-6, IL-8, IL-1β, TNF-α, IL-4, IL-10) were measured. The primary findings for cytokine levels revealed a fixed effect for condition that showed higher IL-8 levels among firefighters who received an 8-h sleep each night. An interaction effect demonstrated differing increases in IL-6 over successive days of work for the SR and CON conditions. Fixed effects for time indicated that IL-6 and IL-4 levels increased, while IL-1β, TNF-α and IL-8 levels decreased. There were no significant effects for IL-10 observed. Findings demonstrate increased IL-8 levels among firefighters who received an 8-h sleep when compared to those who had a restricted 4-h sleep. Firefighters' IL-6 levels increased in both conditions which may indicate that a 4-h sleep restriction duration and/or period (i.e., 2 nights) was not a significant enough stressor to affect this cytokine. Considering the immunomodulatory properties of IL-6 and IL-4 that inhibit pro-inflammatory cytokines, the rise in IL-6 and IL-4, independent of increases in IL-1β and TNF-α, could indicate a non-damaging response to the stress of simulated physical firefighting work. However, given the link between chronically elevated cytokine levels and several diseases, further research is needed to determine if firefighters' IL-8 and IL-6 levels are elevated following repeated firefighting deployments across a fire season and over multiple fire seasons.

Methods for in-place testing of HEPA and iodine filters used in nuclear power plants

International Nuclear Information System (INIS)

Holmberg, R.; Laine, J.

1978-04-01

The purpose of this work was a general investigation of existing in-place test methods and to build an equipment for in-place testing of HEPA and iodine sorption filters. In this work the discussion is limited to methods used in in-place testing of HEPA and iodine sorption filters used in light-water-cooled reactor plants. Dealy systems, built for the separation of noble gases, and testing of them is not discussed in the work. Contaminants present in the air of a reactor containment can roughly be diveded into three groups: aerosols, reactive gases, and noble gases. The aerosols are filtered with HEPA (High Efficiency Particulate Air) filters. The most important reactive gases are molecular iodine and its two compounds: hydrogen iodide and methyl iodide. Of gases to be removed by the filters methyl iodide is the gas most difficult to remove especially at high relative humidities. Impregnated activated charcoal is generally used as sorption material in the iodine filters. Experience gained from the use of nuclear power plants proves that the function of high efficiency air filter systems can not be considered safe until this is proved by in-place tests. In-place tests in use are basically equal. A known test agent is injected upstream of the filter to be tested. The efficiency is calculated from air samples taken from both sides of the filter.

Evolving new technologies in vascular access mandate increased attention to patient safety; an often overlooked yet valuable training tool is simulation. For the end-stage renal disease patient, simulation tools are effective for all aspects of creating access for peritoneal dialysis and hemodialysis. Based on aviation principles, known as crew resource management, we place equal emphasis on team training as individual training to improve interactions between team members and systems, cumulating in improved safety. Simulation allows for environmental control and standardized procedures, letting the trainee practice and correct mistakes without harm to patients, compared with traditional patient-based training. Vascular access simulators range from suture devices, to pressurized tunneled conduits for needle cannulation, to computer-based interventional simulators. Simulation training includes simulated case learning, root cause analysis of adverse outcomes, and continual update and refinement of concepts. Implementation of effective human to complex systems interaction in end-stage renal disease patients involves a change in institutional culture. Three concepts discussed in this article are as follows: (1) the need for user-friendly systems and technology to enhance performance, (2) the necessity for members to both train and work together as a team, and (3) the team assigned to use the system must test and practice it to a proficient level before safely using the system on patients.

Photovoicing the neighbourhood: Understanding the situated meaning of intangible places for ageing-in-place.

Science.gov (United States)

van Hees, Susan; Horstman, Klasien; Jansen, Maria; Ruwaard, Dirk

2017-11-01

Ageing-in-place is considered important for the health of older adults. In this paper, inspired by a constructivist approach to ageing-in-place, we unravel professionals' and older adults' constructions of ageing-in-place. Their perspectives are studied in relation to a policy that aims to develop so-called 'lifecycle-robust neighbourhoods' in the southern part of the Netherlands. We conducted a photovoice study in which 18 older adults (70-85 years) living independently and 14 professionals (social workers, housing consultants, neighbourhood managers and community workers) were asked to photograph and discuss the places they consider important for ageing-in-place. Based on a theoretically informed analysis of the data, we found that professionals primarily consider objective characteristics of neighbourhoods such as access to amenities, mobility and meeting places as important enablers for older adults to remain living independently. Analysis of older adults' photographs and stories show that they associate ageing-in-place with specific lived experiences and attachments to specific, intangible and memory-laden public places. We conclude that exploring these experiences helps to increase current knowledge about place attachment in old age. Copyright © 2017 Elsevier Ltd. All rights reserved.

The increasing availability, use and limitations of administrative data for place-based population health research, and a lack of theory development, created the context for the current paper. We developed a heuristic to interrogate administrative data sets and to help us develop explanatory pathways for linking place and health. Guided by a worked example, we argue that some items in administrative data sets lend themselves to multiple theories, creating problems of inference owing to the implications of using inductive versus deductive reasoning during the research process, and that certain types of theories are privileged when used administrative data bases.

An algorithm for three-dimensional Monte-Carlo simulation of charge distribution at biofunctionalized surfaces

KAUST Repository

Bulyha, Alena

2011-01-01

In this work, a Monte-Carlo algorithm in the constant-voltage ensemble for the calculation of 3d charge concentrations at charged surfaces functionalized with biomolecules is presented. The motivation for this work is the theoretical understanding of biofunctionalized surfaces in nanowire field-effect biosensors (BioFETs). This work provides the simulation capability for the boundary layer that is crucial in the detection mechanism of these sensors; slight changes in the charge concentration in the boundary layer upon binding of analyte molecules modulate the conductance of nanowire transducers. The simulation of biofunctionalized surfaces poses special requirements on the Monte-Carlo simulations and these are addressed by the algorithm. The constant-voltage ensemble enables us to include the right boundary conditions; the dna strands can be rotated with respect to the surface; and several molecules can be placed in a single simulation box to achieve good statistics in the case of low ionic concentrations relevant in experiments. Simulation results are presented for the leading example of surfaces functionalized with pna and with single- and double-stranded dna in a sodium-chloride electrolyte. These quantitative results make it possible to quantify the screening of the biomolecule charge due to the counter-ions around the biomolecules and the electrical double layer. The resulting concentration profiles show a three-layer structure and non-trivial interactions between the electric double layer and the counter-ions. The numerical results are also important as a reference for the development of simpler screening models. © 2011 The Royal Society of Chemistry.

eHealth Technology Competencies for Health Professionals Working in Home Care to Support Older Adults to Age in Place: Outcomes of a Two-Day Collaborative Workshop.

2013-01-01

The demand for care is increasing, whereas in the near future the number of people working in professional care will not match with the demand for care. eHealth technology can help to meet the growing demand for care. Despite the apparent positive effects of eHealth technology, there are still barriers to technology adoption related to the absence of a composite set of knowledge and skills among health care professionals regarding the use of eHealth technology. The objective of this paper is to discuss the competencies required by health care professionals working in home care, with eHealth technologies such as remote telecare and ambient assisted living (AAL), mobile health, and fall detection systems. A two-day collaborative workshop was undertaken with academics across multiple disciplines with experience in working on funded research regarding the application and development of technologies to support older people. The findings revealed that health care professionals working in home care require a subset of composite skills as well as technology-specific competencies to develop the necessary aptitude in eHealth care. This paper argues that eHealth care technology skills must be instilled in health care professionals to ensure that technologies become integral components of future care delivery, especially to support older adults to age in place. Educating health care professionals with the necessary skill training in eHealth care will improve service delivery and optimise the eHealth care potential to reduce costs by improving efficiency. Moreover, embedding eHealth care competencies within training and education for health care professionals ensures that the benefits of new technologies are realized by casting them in the context of the larger system of care. These care improvements will potentially support the independent living of older persons at home. This paper describes the health care professionals' competencies and requirements needed for the use of e

Education in a culture of violence: a critical pedagogy of place in wartime

Science.gov (United States)

Greenwood, David A.

2010-06-01

What is the role of education in wartime? To what extent should environmental and science educators directly address violent conflict and a culture of prolonged war? This article gestures with empathy toward all educators who are working in wartime. It posits that a critical pedagogy of place provides a theoretical framework that contextualizes all environmental work and all education in the context of cultural politics. I argue that a fundamental component of a critical, place-based inquiry must be acknowledging the contested history of colonization with respect to land (environment) and homeland (culture). I cannot think of a place on the planet where this history is as complex and contested than it is in Israel and Palestine. However, colonization and its legacy is a shared reality around the world, and acknowledging the context of colonization should not be limited to inquiry in places where the bombs are still smoldering and where the rubble has yet to be cleared. Acknowledging colonization may be especially appropriate in the US, where the historical record of militarized colonization remains hidden behind the myths of global "progress" for the world's remaining "superpower."

Social place-cells in the bat hippocampus.

Social animals have to know the spatial positions of conspecifics. However, it is unknown how the position of others is represented in the brain. We designed a spatial observational-learning task, in which an observer bat mimicked a demonstrator bat while we recorded hippocampal dorsal-CA1 neurons from the observer bat. A neuronal subpopulation represented the position of the other bat, in allocentric coordinates. About half of these "social place-cells" represented also the observer's own position-that is, were place cells. The representation of the demonstrator bat did not reflect self-movement or trajectory planning by the observer. Some neurons represented also the position of inanimate moving objects; however, their representation differed from the representation of the demonstrator bat. This suggests a role for hippocampal CA1 neurons in social-spatial cognition.

Place Branding as Efficient Management Tool for Local Government

Directory of Open Access Journals (Sweden)

Rodica PETREA

2013-12-01

Full Text Available The economic liberalism, globalization and more recently the economic crisis are general phenomena leading to changes of territorial management practices. Within these practices, place marketing and branding are of crucial importance in promoting an image of the city and bringing some added value to a place. Although an emerging challenging problem for local authorities, few scholars are currently addressing the subject, in terms of delivering a branding modus operandi for the practitioners, be they local authorities or private agencies. The present paper conducts an in-depth analysis of the most recent writings showing how product marketing techniques apply to place marketing, with an emphasis on city branding, presenting the manner in which the place branding process was improved in two of the most representative cities of Transylvania: Sibiu and Cluj-Napoca. The paper’s main objective is to highlight the role of territorial marketing which can become, through one of its components, namely place branding, an important trigger for the local communities development by the means of strategic planning. In this respect, the present work displays an overview of some of the most illustrative theoretical models regarding city branding, an insight on the Romanian city branding process within the two aforementioned cities and, finally, some brief recommendations regarding the place and the role of branding process for local authorities. The paper assumes that although place branding is an efficient tool for promoting a territory’s identity (already proven in several European cities, Romania is at the beginning of this process. The few significant achievements (the ones from Sibiu and Cluj-Napoca being the most notable still cannot make the most of their urban identities and values, neither at national, nor at international level. Last but not least, this kind of papers might raise some awareness among local stakeholders on the importance of these

Integration of THM-experimental work and modelling

Document available in extended abstract form only. Long-term safety of the bentonite buffer relies heavily on appropriate saturation of bentonite buffer resulting evidently on adequate swelling pressure low hydraulic conductivity. After transient period after installation of buffer components the buffer swelling pressure is to remain sufficiently high regardless of e.g. the conditions during the early evolution promoting hydrothermal alteration. For these reasons it is of central importance to characterise different 'underlying saturation flow regimes', USFRs, and the related time dependent fluxes in various parts of buffer in then currently prevailing conditions. The THM processes govern the behaviour from transient to fully saturated state and occur during long periods of time from tens of years up to hundreds or even more. Therefore it is important to be able to understand the underlying processes sufficiently and to develop proper modelling techniques. This can be carried out only by integrating testing and modelling. THM-modelling has also important role in design development phase when different engineering techniques e.g. for wetting of buffer are evaluated. This paper presents the integration of THM-experimental work and modelling carried out in Finland and elsewhere for the development of the buffer designs. The primary objective of this work is to provide experimental and modelling data for assessing the behaviour of bentonite buffer during saturation with respect to fulfilling the performance targets. The development of numerical methods allows to simulate the different processes which take place in materials and to understand them better. In laboratory testing, the numerical methods allow us to simulate the tests and to choose the best geometry and boundary conditions and to verify the experimental designs. The clay barrier behaviour is complex because there are some phenomena coupled: heat flow, water flow in vapour and liquid phases and

Determination of the size of the gas emission zone, the locations of gas sources within, and especially the amount of gas retained in those zones is one of the most important steps for designing a successful methane control strategy and an efficient ventilation system in longwall coal mining. The formation of the gas emission zone and the potential amount of gas-in-place (GIP) that might be available for migration into a mine are factors of local geology and rock properties that usually show spatial variability in continuity and may also show geometric anisotropy. Geostatistical methods are used here for modeling and prediction of gas amounts and for assessing their associated uncertainty in gas emission zones of longwall mines for methane control.This study used core data obtained from 276 vertical exploration boreholes drilled from the surface to the bottom of the Pittsburgh coal seam in a mining district in the Northern Appalachian basin. After identifying important coal and non-coal layers for the gas emission zone, univariate statistical and semivariogram analyses were conducted for data from different formations to define the distribution and continuity of various attributes. Sequential simulations performed stochastic assessment of these attributes, such as gas content, strata thickness, and strata displacement. These analyses were followed by calculations of gas-in-place and their uncertainties in the Pittsburgh seam caved zone and fractured zone of longwall mines in this mining district. Grid blanking was used to isolate the volume over the actual panels from the entire modeled district and to calculate gas amounts that were directly related to the emissions in longwall mines.Results indicated that gas-in-place in the Pittsburgh seam, in the caved zone and in the fractured zone, as well as displacements in major rock units, showed spatial correlations that could be modeled and estimated using geostatistical methods. This study showed that GIP volumes may

Full Text Available Floods are a problem that may occur in many parts of the world, but in certain places it happens more frequently, for example in Villahermosa, Mexico, which can be confirmed with the floods of 2000, 2007, 2009 and 2010. In this work the IBER code is used (freely available at http://www.iberaula.es to recreate the scenarios occurred in October 2007, and the numerical results are compared with data provided/collected by CONAGUA in the Hydrometeorological station Gaviotas. The scenarios of the 1st October, 30th October and 31st October were simulated. A steady state was obtained in the simulation of the 1st October, this state was used as initial condition for the simulation of the 30th October, in which are reproduced the conditions of the 31st October. In addition, a sensibility analysis was carried out for the wetting drying parameter and the Courant number.
