To compare the self-perceived sleepiness of Canadian anesthesia residents providing modified on-call duties (12-16 h) vs. traditional on-call duties (24 h). A 25-item online survey was distributed to all Canadian anesthesia residents who, at that time, were on anesthesia rotations. The survey assessed resident demographics, perceived work patterns, and sleepiness, as well as their opinions on resident work hour reform. Self-perceived sleepiness was quantified using the validated Epworth sleepiness scale (ESS). Three hundred eight of 400 (77%) eligible Canadian anesthesia residents completed the survey. Forty-three percent of residents who worked traditional on-call (duration 24.1 +/- 0.5 h) shifts and 48% of residents who worked modified on-call (duration 15.5 +/- 1.8 h) shifts met ESS criteria for excessive daytime sleepiness. Overall mean ESS scores did not differ significantly between the traditional (9.1 +/- 4.9) and the modified call groups (9.5 +/- 4.8). Residents with an on-call frequency of >or=1:4 days or those who slept

Background The purpose of this study was to describe Canadian general surgery residents’ perceptions regarding potential implementation of work-hour restrictions. Methods An ethics review board–approved, Web-based survey was submitted to all Canadian general surgery residency programs between April and July 2009. Questions evaluated the perceived effects of an 80-hour work week on length of training, operative exposure, learning and lifestyle. We used the Fisher exact test to compare senior and junior residents’ responses. Results Of 360 residents, 158 responded (70 seniors and 88 juniors). Among them, 79% reported working 75–100 hours per week. About 74% of seniors believed that limiting their work hours would decrease their operative exposure; 43% of juniors agreed (p < 0.001). Both seniors and juniors thought limiting their work hours would improve their lifestyle (86% v. 96%, p = 0.12). Overall, 60% of residents did not believe limiting work hours would extend the length of their training. Regarding 24-hour call, 60% of juniors thought it was hazardous to their health; 30% of seniors agreed (p = 0.001). Both senior and junior residents thought abolishing 24-hour call would decrease their operative exposure (84% v. 70%, p = 0.21). Overall, 31% of residents supported abolishing 24-hour call. About 47% of residents (41% seniors, 51% juniors, p = 0.26) agreed with the adoption of the 80-hour work week. Conclusion There is a training-level based dichotomy of opinion among general surgery residents in Canada regarding the perceived effects of work hour restrictions. Both groups have voted against abolishing 24-hour call, and neither group strongly supports the implementation of the 80-hour work week. PMID:22269303

Rotter, R G

2009-06-01

With the move towards globalized international commerce and trade, a call for harmonization of medical device regulatory requirements and practices has evolved. The purpose of the Global Harmonization Task Force (GHTF) is to encourage convergence of regulatory requirements and practices at a global level through consensus to achieve four principle goals: promote safety, quality and performance/effectiveness of medical devices; encourage technological innovation; foster international trade; and serve as a forum of information exchange - all in the interests of protecting and promoting public health. The GHTF is governed by a Steering Committee, and the principle development of the GHTF regulatory model has been, and continues to be, done through five working groups known as Study Groups and supplemented recently by the creation of several Ad Hoc Working Groups. Since its creation in 1992, the members of the GHTF have worked collaboratively to develop what is now ready to be called a global model for the regulation of medical devices.

International space agencies around the world are currently developing optical communication systems for Near Earth and Deep Space applications for both robotic and human rated spacecraft. These applications include both links between spacecraft and links between spacecraft and ground. The Interagency Operation Advisory Group (IOAG) has stated that there is a strong business case for international cross support of spacecraft optical links. It further concluded that in order to enable cross support the links must be standardized. This paper will overview the history and structure of the space communications international standards body, the Consultative Committee for Space Data Systems (CCSDS), that will develop the standards and provide an update on the proceedings of the Optical Communications Working Group within CCSDS. This paper will also describe the set of optical communications standards being developed and outline some of the issues that must be addressed in the next few years. The paper will address in particular the ongoing work on application scenarios for deep space to ground called High Photon Efficiency, for LEO to ground called Low Complexity, for inter-satellite and near Earth to ground called High Data Rate, as well as associated atmospheric measurement techniques and link operations concepts.

Nationwide, emergency response systems depend on 9-1-1 telecommunicators to prioritize, triage, and dispatch assistance to those in distress. 9-1-1 call center telecommunicators (TCs) are challenged by acute and chronic workplace stressors: tense interactions with citizen callers in crisis; overtime; shift-work; ever-changing technologies; and negative work culture, including co-worker conflict. This workforce is also subject to routine exposures to secondary traumatization while handling calls involving emergency situations and while making time urgent, high stake decisions over the phone. Our study aims to test the effectiveness of a multi-part intervention to reduce stress in 9-1-1 TCs through an online mindfulness training and a toolkit containing workplace stressor reduction resources. The study employs a randomized controlled trial design with three data collection points. The multi-part intervention includes an individual-level online mindfulness training and a call center-level organizational stress reduction toolkit. 160 TCs will be recruited from 9-1-1 call centers, complete a baseline survey at enrollment, and are randomly assigned to an intervention or a control group. Intervention group participants will start a 7-week online mindfulness training developed in-house and tailored to 9-1-1 TCs and their call center environment; control participants will be "waitlisted" and start the training after the study period ends. Following the intervention group's completion of the mindfulness training, all participants complete a second survey. Next, the online toolkit with call-center wide stress reduction resources is made available to managers of all participating call centers. After 3 months, a third survey will be completed by all participants. The primary outcome is 9-1-1 TCs' self-reported symptoms of stress at three time points as measured by the C-SOSI (Calgary Symptoms of Stress Inventory). Secondary outcomes will include: perceptions of social work environment (measured by metrics of social support and network conflict); mindfulness; and perceptions of social work environment and mindfulness as mediators of stress reduction. This study will evaluate the effectiveness of an online mindfulness training and call center-wide stress reduction toolkit in reducing self-reported stress in 9-1-1 TCs. The results of this study will add to the growing body of research on worksite stress reduction programs.

2013-01-01

Background In the Millennium Villages Project site of Bonsaaso, Ghana, the Health Team is using a mobile phone closed user group to place calls amongst one another at no cost. Methods In order to determine the utilization and acceptability of the closed user group amongst users, social network analysis and qualitative methods were used. Key informants were identified and interviewed. The key informants also kept prospective call journals. Billing statements and de-identified call data from the closed user group were used to generate data for analyzing the social structure revealed by the network traffic. Results The majority of communication within the closed user group was personal and not for professional purposes. The members of the CUG felt that the group improved their efficiency at work. Conclusions The methods used present an interesting way to investigate the social structure surrounding communication via mobile phones. In addition, the benefits identified from the exploration of this closed user group make a case for supporting mobile phone closed user groups amongst professional groups. PMID:24007331

The role of general and specific stressors in the health and well-being of call centre operators.

PubMed

Mellor, David; Moore, Kathleen A; Siong, Zhong Ming Benjamin

2015-01-01

The call centre industry has developed a reputation for generating a highly stressful work environment with high absenteeism and turnover rates. Research has identified role ambiguity, role conflict, role overload, and work-family conflict as common stressors in other settings. Call centre research has additionally identified performance monitoring, job design and job opportunities as call centre specific stressors. This study investigated the impact of the identified stressors on burnout, somatic symptomology, and turnover intent among 126 call centre representatives (CCRs) from 11 call centres in metropolitan Melbourne, Australia. Hierarchical multiple regression analyses found that the common organizational stressors significantly explained between 10% and 53% of the variance in somatic symptomology, burnout (all 3 dimensions) and turnover intent. An additional amount of variance, between 6% and 22% in each of these dependent measures was significantly accounted for by the grouped call centre specific stressors. Overall, common organizational stressors and call centre specific stressors both significantly and independently contributed to burnout, somatic symptomology and turnover intent. These findings are discussed in relation to previous research, and suggestions for improved practice within call centres to safeguard the well-being of workers and for future research are provided.

Out-of-hours centres provide telephone support to patients with medical problems. In most of these centres specially-trained nurses handle incoming telephone calls. They assess patients' needs, the degree of urgency, and determine the level of care required. Assessment of the medical problem and the quality of 'care-by-phone' depend on the medical and communication skills of the call handlers. To develop a valid, reliable, and practical rating scale to evaluate the communication skills of call handlers working at an out-of-hours centre and to improve quality of communication. Qualitative study with focus groups followed by validation of the rating scale and measurement of reliability (internal consistency). Out-of-hours centres in the Netherlands. A focus group developed the rating scale. Experts with experience in training and evaluating communication skills of medical students and GPs commented on the scale to ensure content validity. The reliability of the rating scale was tested in a pilot in which ten specially-trained assessors scored six telephone calls each. The scale, known as the RICE rating scale, has 17 items divided over four different phases of the telephone consultation: Reason for calling; Information gathering; Conclusion; and Evaluation (RICE). Content validity of the scale was assessed by two experts. Reliability of the scale tested in the pilot was 0.73 (Cronbach's alpha). Establishing a rating scale to assess the communication skills of call handlers which meets common scientific demands, such as content validity and reliability, proved successful. This instrument can be used to give feedback to call handlers.

2013-01-01

This paper describes an e-learning system that is expected to further enhance the educational process in computer-based tutoring systems by incorporating collaboration between students and work in groups. The resulting system is called "Comulang" while as a test bed for its effectiveness a multiple language learning system is used. Collaboration is supported by a user modeling module that is responsible for the initial creation of student clusters, where, as a next step, working groups of students are created. A machine learning clustering algorithm works towards group formatting, so that co-operations between students from different clusters are attained. One of the resulting system's basic aims is to provide efficient student groups whose limitations and capabilities are well balanced.

Can labour contract differences in health and work-related attitudes be explained by quality of working life and job insecurity?

PubMed

Wagenaar, Alfred F; Kompier, Michiel A J; Houtman, Irene L D; van den Bossche, Seth; Smulders, Peter; Taris, Toon W

2012-10-01

We hypothesise that due to a lower quality of working life and higher job insecurity, the health and work-related attitudes of temporary workers may be less positive compared to permanent workers. Therefore, we aimed to (1) examine differences between contract groups (i.e. permanent contract, temporary contract with prospect of permanent work, fixed-term contract, temporary agency contract and on-call contract) in the quality of working life, job insecurity, health and work-related attitudes and (2) investigate whether these latter contract group differences in health and work-related attitudes can be explained by differences in the quality of working life and/or job insecurity. Data were collected from the Netherlands Working Conditions Survey 2008 (N = 21,639), and Hypotheses were tested using analysis of variance and cross-table analysis. Temporary work was associated with fewer task demands and lower autonomy and was more often passive or high-strain work, while permanent work was more often active work. Except for on-call work, temporary work was more insecure and associated with worse health and work-related attitude scores than permanent work. Finally, the quality of working life and job insecurity partly accounted for most contract differences in work-related attitudes but not in health. Especially agency workers have a lower health status and worse work-related attitudes. Job redesign measures regarding their quality of working life and job insecurity are recommended.

The impact of implementing the European Working Time Directive (EWTD) and the consequent reduction in hours of work has led to concerns about training. This retrospective study compared total caseload, obstetric caseload, out-of-hours caseload and supervision levels of trainee anaesthetists in one region of the UK (Wessex) before and after the implementation of EWTD compliant rotas. Anaesthetic trainee logbooks submitted at the annual Record of In-Training Assessment were compared between the years 1999 and 2006. The logbook data was divided into two groups, group A (13-h shift) and group B (24-h on-call rota). There was no difference in total caseload, obstetric caseload or supervision. Out-of-hours caseload was greater in group A (p < 0.01).

2017-06-01

On-call work is becoming an increasingly common work pattern, yet the human impacts of this type of work are not well established. Given the likelihood of calls to occur outside regular work hours, it is important to consider the potential impact of working on-call on stress physiology and sleep. The aims of this review were to collate and evaluate evidence on the effects of working on-call from home on stress physiology and sleep. A systematic search of Ebsco Host, Embase, Web of Science, Scopus and ScienceDirect was conducted. Search terms included: on-call, on call, standby, sleep, cortisol, heart rate, adrenaline, noradrenaline, nor-adrenaline, epinephrine, norepinephrine, nor-epinephrine, salivary alpha amylase and alpha amylase. Eight studies met the inclusion criteria, with only one study investigating the effect of working on-call from home on stress physiology. All eight studies investigated the effect of working on-call from home on sleep. Working on-call from home appears to adversely affect sleep quantity, and in most cases, sleep quality. However, studies did not differentiate between night's on-call from home with and without calls. Data examining the effect of working on-call from home on stress physiology were not sufficient to draw meaningful conclusions. Copyright © 2016 Elsevier Ltd. All rights reserved.

The night float system has been used by some institutions as a strategy to decrease the burden of call on resident quality of life in level-1 trauma centres. The purpose of this study was to determine whether there are differences in quality of life, work-related stressors and educational experience between orthopedic surgery residents in the night float and standard call systems at 2 level-1 trauma centres. Methods We conducted a prospective cohort study at 2 level-1 trauma hospitals comprising a standard call (1 night in 4) group and a night float (5 14-hour shifts [5 pm–7 am] from Monday to Friday) group for each hospital. Over the course of a 6-month rotation, each resident completed 3 weeks of night float. The remainder of the time on the trauma service consists of clinical duties from 6:30 am to 5:30 pm on a daily basis and intermittent coverage of weekend call only. Residents completed the Short Form-36 (SF-36) general quality-of-life questionnaire, as well as questionnaires on stress level and educational experience before the rotation (baseline) and at 2, 4 and 6 months. We performed an analysis of covariance to compare between-group differences using the baseline scores as covariates and Wilcoxon signed-rank tests (nonparametric) to determine if the residents’ SF-36 scores were different from the age- and sex-matched Canadian norms. We analyzed predictors of resident quality of life using multivariable mixed models. Results Seven residents were in the standard call group and 9 in the night float group, for a total of 16 residents (all men, mean age 35.1 yr). Controlling for between-group differences at baseline, residents on the night float rotation had significantly lower role physical, bodily pain, social function and physical component scale scores over the 6-month observation period. Compared with the Canadian normative population, the night float group had significantly lower SF-36 scores in all subscales except for bodily pain. There were no differences noted between the standard call group and Canadian norms at 6 months. No differences in educational benefits and stress level were measured between the 2 groups. Lack of time for physical activity was only significant in the night float group. Regression analysis demonstrated that the increased number of hours in hospital correlated with significantly lower SF-36 scores in almost all domains. Conclusion Our study suggests that the residents in the standard call group had better health-related quality of life compared with those in the night float group. No differences existed in subjective educational benefits and stress level between the groups. PMID:21251429

The present study sought to describe call-center working conditions and call-handlers' subjective experience of their work. A transversal study was performed in companies followed by the 47 occupational physicians taking part. A dedicated questionnaire included one part on working conditions (work-station organization, task types, work schedules, and controls) and another on the perception of working conditions. Psychosocial risk factors were explored by three dimensions of the Karasek questionnaire, decision latitude, psychological demands and social support. A descriptive stage characterized the population and quantified the frequency of the various types of work organization, working conditions and perception. Certain working conditions data were crossed with perception data. The total sample comprised 2,130 call-handlers from around 100 different companies. The population was 71.9% female, with a mean age of 32.4 years. The general educational level was high, with 1,443 (68.2%) of call-handlers having at least 2 years' higher education; 1,937 of the workers (91.2%) had permanent work contracts. Some working situations were found to be associated with low decision latitude and high psychological demands: i.e., where the schedule (full-time or part-time) was imposed, where the call-handlers had not chosen to work in a call-center, or where they received prior warning of controls. Moreover, the rate of low decision latitude and high psychological demands increased with seniority in the job. The rate of low decision latitude increased with the size of the company and was higher when call duration was imposed and when the call-handlers handled only incoming calls. The rate of high psychological demands was higher when call-handlers handled both incoming and outgoing calls. This study confirmed the high rate of psychosocial constraints for call-handlers and identified work situations at risk.

Effective interventions to prevent work stress and to improve health, well-being, and performance of employees are of the utmost importance. This quasi-experimental intervention study presents a specific method for diagnosis of psychosocial risk factors at work and subsequent development and implementation of tailored work stress interventions, the so-called DISCovery method. This method aims at improving employee health, well-being, and performance by optimizing the balance between job demands, job resources, and recovery from work. The aim of the study is to quantitatively assess the effectiveness of the DISCovery method in hospital care. Specifically, we used a three-wave longitudinal, quasi-experimental multiple-case study approach with intervention and comparison groups in health care work. Positive changes were found for members of the intervention groups, relative to members of the corresponding comparison groups, with respect to targeted work-related characteristics and targeted health, well-being, and performance outcomes. Overall, results lend support for the effectiveness of the DISCovery method in hospital care. PMID:29438350

Do ergonomics improvements increase computer workers' productivity?: an intervention study in a call centre.

PubMed

Smith, Michael J; Bayehi, Antoinette Derjani

2003-01-15

This paper examines whether improving physical ergonomics working conditions affects worker productivity in a call centre with computer-intensive work. A field study was conducted at a catalogue retail service organization to explore the impact of ergonomics improvements on worker production. There were three levels of ergonomics interventions, each adding incrementally to the previous one. The first level was ergonomics training for all computer users accompanied by workstation ergonomics analysis leading to specific customized adjustments to better fit each worker (Group C). The second level added specific workstation accessories to improve the worker fit if the ergonomics analysis indicated a need for them (Group B). The third level met Group B requirements plus an improved chair (Group A). Productivity data was gathered from 72 volunteer participants who received ergonomics improvements to their workstations and 370 control subjects working in the same departments. Daily company records of production outputs for each worker were taken before ergonomics intervention (baseline) and 12 months after ergonomics intervention. Productivity improvement from baseline to 12 months post-intervention was examined across all ergonomics conditions combined, and also compared to the control group. The findings showed that worker performance increased for 50% of the ergonomics improvement participants and decreased for 50%. Overall, there was a 4.87% output increase for the ergonomics improvement group as compared to a 3.46% output decrease for the control group. The level of productivity increase varied by the type of the ergonomics improvements with Group C showing the best improvement (9.43%). Even though the average production improved, caution must be used in interpreting the findings since the ergonomics interventions were not successful for one-half of the participants.

To examine sedentary time, prolonged sedentary bouts and physical activity in Australian employees from different workplace settings, within work and non-work contexts. A convenience sample of 193 employees working in offices (131), call centres (36) and customer service (26) was recruited. Actigraph GT1M accelerometers were used to derive percentages of time spent sedentary (<100 counts per minute; cpm), in prolonged sedentary bouts (≥20 minutes or ≥30 minutes), light-intensity activity (100-1951 cpm) and moderate-to-vigorous physical activity (MVPA; ≥1952 cpm). Using mixed models adjusted for confounders, these were compared for: work days versus non-work days; work hours versus non-work hours (work days only); and, across workplace settings. Working hours were mostly spent sedentary (77.0%, 95%CI: 76.3, 77.6), with approximately half of this time accumulated in prolonged bouts of 20 minutes or more. There were significant (p<0.05) differences in all outcomes between workdays and non-work days, and, on workdays, between work- versus non-work hours. Results consistently showed "work" was more sedentary and had less light-intensity activity, than "non-work". The period immediately after work appeared important for MVPA. There were significant (p<0.05) differences in all sedentary and activity outcomes occurring during work hours across the workplace settings. Call-centre workers were generally the most sedentary and least physically active at work; customer service workers were typically the least sedentary and the most active at work. The workplace is a key setting for prolonged sedentary time, especially for some occupational groups, and the potential health risk burden attached requires investigation. Future workplace regulations and health promotion initiatives for sedentary occupations to reduce prolonged sitting time should be considered.

With the widespread use of smartphones, text messaging has become an accepted form of communication for both social and professional use in medicine. To our knowledge no published studies have assessed the prevalence and use of short message service (SMS) texting by doctors on call. We have used an online questionnaire to seek information from doctors in a large NHS Trust in the UK about their use of texting while on call, what they use it for, and whether they send images relevant to patients' care. We received 302 responses (43% response rate), of whom 166 (55%) used SMS while on call. There was a significant association between SMS and age group (p=0.005), with the 20-30-year-old group using it much more than the other age groups. Doctors in the surgical specialties used it significantly less than those in other speciality groups (p<0 .001). Texting while on call was deemed to be safe and reliable (p<0.001). Eighteen clinicians (11%) admitted to routinely sending images of patients by text, despite some being identifiable. Texting was mainly used to update colleagues on patients' progress and give information about times of ward rounds and meetings. With the increasing use of texting in healthcare, much of which seems to be unregulated, further work and detailed guidance is required on what information may be given to ensure confidentiality and that SMS is a safe and acceptable method of communication to use when on call.

Work-related musculoskeletal disorders (WMSDs) have been documented among various occupational groups in Nigeria. However, there is limited data on the prevalence of WMSDs among call center operators (CCOs). To determine the prevalence of WMSDs among CCOs in Nigeria and to explore the extent to which these discomforts impact the daily work activities of the respondents. 374 respondents who were randomly selected from 4 telecommunication companies in Lagos State, Nigeria, participated in this study. They were asked to complete a pre-tested questionnaire designed to capture the prevalence, impact and associated risk factors of WMSDs among CCOs. 42% and 65.2% of respondents experienced at least one WMSDs in the past 7 days, and 12 months, respectively. Women and CCOs who received calls with hand-held phones rather than headsets reported more discomforts during both 7 days and 12 months periods. Neck, shoulder, upper back, and lower back were the most affected areas during past 7 days and 12 months. Discomforts in the neck, low back, and knees prevented most of the respondents from performing their daily work. WMSDs have a serious impact on the daily job activities of the CCOs in Nigeria.

The objectives of this study were to (1) examine whether need for recovery differs between workers (i) not on-call, (ii) on-call but not called and (iii) on-call and called, and (2) investigate the associations between age, health, work and social characteristics with need for recovery for the three scenarios (i-iii). Cross-sectional data of N = 169 Dutch distal on-call workers were analysed with multivariate logistic regression. Need for recovery differed significantly between the three scenarios (i-iii), with lowest need for recovery for scenario (i) 'not on-call' and highest need for recovery for scenario (iii) 'on-call and called'. Poor mental health and high work-family interference were associated with higher need for recovery in all three scenarios (i-iii), whereas high work demands was only associated with being on-call (ii and iii). The results suggest that the mere possibility of being called affects the need for recovery, especially in workers reporting poor mental health, high-work demands and work-family interference. Practitioner summary: On-call work is a scarcely studied but demanding working time arrangement. We examined need for recovery and its associations with age, health, work and social characteristics among distal on-call workers. The results suggest that the mere possibility of being called can affect worker well-being and need for recovery.

Work on the Super and the Study of Atmospheric Ignition

NASA Astrophysics Data System (ADS)

2001-03-01

By 1951, the group of young faculty (Bob Gluckstern and me), post doctoral fellows and graduate students, was comfortably established in Sloane Laboratory, and as "The Breit Group", in the department of physics at Yale. We didn't consciously separate ourselves from others in the department, and no one seemed to put us apart, but the association with Breit gave us a special "aura"--sometimes as objects of pity. Any project that involved the group as a whole, or a significant part of it, was discussed with Bob and me, and sometime in 1951 Breit called us in to consider a request that we look at the possibility of atmospheric ignition by a "Super" - as we still called it then, after Edward Teller. At the end of my stay at Los Alamos, in the summer of 1946, we youngsters had many bull sessions about that "Super", and the possibility of controlled fusion energy. We were confident that the former would be working in perhaps five years, and the latter within ten. After all, Han Bethe had shown us how the sun made its energy, and all that was needed to do was to replace a couple of his slow beta decays with something faster. As I write, some fifty-four years later, we still haven't got fusion energy for power. Our crystal balls were cloudier than Vicky Weisskopf's were to be! But I knew some of the lingo, and had worked out the way radiation penetrates the atmosphere (for understanding the Bikini tests), so in 1951, initially drew the task of looking at opacity, a key question in the bomb itself, and in the possibility of atmospheric ignition. Most of our limited work on the bomb was checking calculations that had been done by others as the Teller-Ulam design was being put together. At least some work on atmospheric ignition had already been done as well, but Teller wanted the "most careful physicist he knew" to do the definitive calculations, so Breit got the call. I do not recall all the members of the group who worked on the project and for that I apologize - no private notes were allowed because the work was classified. But in addition to Bob Gluckstern, I recall, for reasons that will appear, that John McHale was one of the project workers. At one point I think we were all working on nitrogen reactions ...

This year, the World Health Organization focuses on restoring dignity and respect to health care workers. The aim of this study was to investigate the workplace stressors in physicians. The present study was performed in the period 2002 - 2004, among physicians treated in the Health Center Novi Sad. The examinees were asked to fill out a questionnaire--a workplace survey--to identify workplace stressors by using a self-evaluation method The physicians were divided into three groups: those practicing surgery (S), internal medicine (IM) and preventive-diagnostics (PD). Statistical analysis was done using SPSS and STATISTICA software. The sample included 208 physicians with an average age of 40 years (SD = 7,1); average work experience of 22 years (SD = 8,1). 65 physicians from group S and 108 physicians from group IM, identified the following workplace stressors: treating patients in life-threatening situations (47.7%, 30.6%, respectfully); on-call duty (13.8%, 12%); low salary (10.8%, 10.2%); limited diagnostic and therapeutic resources in the IM group. 35 physicians from the DP group identified the following stressors: low salary (25%), treating patients in life-threatening situations and a great number of patients (16%). The analysis of all examined physicians revealed the following workplace stressors: treating patients in life-threatening situations (34.6%), low salary (13%), on-call duty and overtime, and too many patients per physician (11.5%). Restoring the reputation of health workers can be done by providing new equipment to resolve life-threatening situations, by increasing salaries, reducing on-call time, as well as the number of patients. Generally speaking, this should help to improve the quality of work in the health care system, in accordance with the recommendations of the WHO.

On-call work: To sleep or not to sleep? It depends.

PubMed

Ferguson, Sally A; Paterson, Jessica L; Hall, Sarah J; Jay, Sarah M; Aisbett, Brad

On-call working time arrangements are increasingly common, involve work only in the event of an unpredictable incident and exist primarily outside of standard hours. Like other non-standard working time arrangements, on-call work disrupts sleep and can therefore have negative effects on health, safety and performance. Unlike other non-standard working time arrangements, on-call work often allows sleep opportunities between calls. Any sleep obtained during on-call periods will be beneficial for waking performance. However, there is evidence that sleep while on call may be of substantially reduced restorative value because of the expectation of receiving the call and apprehension about missing the call. In turn, waking from sleep to respond to a call may be associated with temporary increases in performance impairment. This is dependent on characteristics of both the preceding sleep, the tasks required upon waking and the availability and utility of any countermeasures to support the transition from sleep to wake. In this paper, we critically evaluate the evidence both for and against sleeping during on-call periods and conclude that some sleep, even if it is of reduced quality and broken by repeated calls, is a good strategy. We also note, however, that organisations utilising on-call working time arrangements need to systematically manage the likelihood that on-call sleep can be associated with temporary performance impairments upon waking. Given that the majority of work in this area has been laboratory-based, there is a significant need for field-based investigations of the magnitude of sleep inertia, in addition to the utility of sleep inertia countermeasures. Field studies should include working with subject matter experts to identify the real-world impacts of changes in performance associated with sleeping, or not sleeping, whilst on call.

Many doctors report working excessively demanding schedules that comply with the European Working Time Directive (EWTD). We compared groups of junior doctors working on different schedules in order to identify which features of schedule design most negatively affected their fatigue and well-being in recent weeks. Completed by 336 doctors, the questionnaires focused on the respondents' personal circumstances, work situation, work schedules, sleep, and perceptions of fatigue, work-life balance and psychological strain. Working 7 consecutive nights was associated with greater accumulated fatigue and greater work-life interference, compared with working just 3 or 4 nights. Having only 1 rest day after working nights was associated with increased fatigue. Working a weekend on-call between 2 consecutive working weeks was associated with increased work-life interference. Working frequent on-calls (either on weekends or during the week) was associated with increased work-life interference and psychological strain. Inter-shift intervals of <10 hours were associated with shorter periods of sleep and increased fatigue. The number of hours worked per week was positively associated with work-life interference and fatigue on night shifts. The current findings identify parameters, in addition to those specified in the EWTD, for designing schedules that limit their impact on doctors' fatigue and well-being.

Difference between Leisure and Work Contexts: The Roles of Perceived Enjoyment and Perceived Usefulness in Predicting Mobile Video Calling Use Acceptance

Zhou, Ronggang; Feng, Caihong

2017-01-01

There is a rapidly growing body of literature on mobile video calling, which is a promising communication technology; however, little research has focused on user acceptance of mobile video calling, especially in different use contexts. This study explored factors (especially perceived enjoyment) influencing the intention of users to employ video calling in different contexts (a work and a leisure context) by applying the technology acceptance model (TAM) combined with the theory of planned behavior. The revised research model differentiated external factors (subjective norms and personal innovativeness) from internal factors (perceived usefulness, perceived ease of use (PEU), perceived enjoyment, and intention to use mobile video calling). In addition, the current study investigated predictors of perceived enjoyment across these two contexts. With the use of a structured questionnaire, participants were divided in two groups and completed self-report measures related to one context; a total of 386 student respondents’ responses were analyzed. The results indicated that users’ intentions were directly predicted by their perceived enjoyment of video calling (β ≥ 0.35) and the call’s perceived usefulness (β ≥ 0.27) and PEU (β = 0.13, only for the leisure context), which jointly explained at least 55.6% of the variance in use intention. In addition to the effects of these predictors on mobile video calling use acceptance, an assessment of the moderating effects of different contexts indicated that perceived enjoyment played a more important role in influencing intention for the leisure context, while perceived usefulness appeared to be more important for the work context. This study’s findings are important in that they provide strong support for the necessity of distinguishing among different types of contexts when predicting users’ intentions to use video calling. Furthermore, the results showed that perceived enjoyment was most significantly influenced by perceived usefulness (β ≥ 0.61), followed by PEU (β ≥ 0.13). In summary, the roles of core TAM variables (especially perceived enjoyment and perceived usefulness) and of external factors (subjective norms and personal innovativeness) differed between the leisure and work contexts. The implications of these findings are discussed. PMID:28337166

Abstraction of complex concepts with a refined partial-area taxonomy of SNOMED

Wang, Yue; Halper, Michael; Wei, Duo; Perl, Yehoshua; Geller, James

2012-01-01

An algorithmically-derived abstraction network, called the partial-area taxonomy, for a SNOMED hierarchy has led to the identification of concepts considered complex. The designation “complex” is arrived at automatically on the basis of structural analyses of overlap among the constituent concept groups of the partial-area taxonomy. Such complex concepts, called overlapping concepts, constitute a tangled portion of a hierarchy and can be obstacles to users trying to gain an understanding of the hierarchy’s content. A new methodology for partitioning the entire collection of overlapping concepts into singly-rooted groups, that are more manageable to work with and comprehend, is presented. Different kinds of overlapping concepts with varying degrees of complexity are identified. This leads to an abstract model of the overlapping concepts called the disjoint partial-area taxonomy, which serves as a vehicle for enhanced, high-level display. The methodology is demonstrated with an application to SNOMED’s Specimen hierarchy. Overall, the resulting disjoint partial-area taxonomy offers a refined view of the hierarchy’s structural organization and conceptual content that can aid users, such as maintenance personnel, working with SNOMED. The utility of the disjoint partial-area taxonomy as the basis for a SNOMED auditing regimen is presented in a companion paper. PMID:21878396

Post-duty psychomotor performance in young and senior anaesthetists.

2006-03-01

The level of performance in junior and senior anaesthetists was investigated after 24-h shift working and on-call duties. Pre- and post-duty psychomotor function, influence on response time, cognitive function and well-being in 23 individuals (13 junior and 12 senior anaesthetists) was assessed before and after 24-h in-house on-call duty. Subjective perception of tiredness and concentration abilities was estimated by applying a visual analogue scale. The self-assessed tiredness prior to duty was high in both age groups and significantly increased in senior anaesthetists after night duty (P = 0.01). Post-duty impairment of concentration abilities was reported in both groups. Comparing results from pre- and post-duty psychometric testing showed a comparable decline in junior and senior anaesthetists as well. Assessment of burnout showed a significant lack of personal accomplishment in junior anaesthetists as compared to their older colleagues (P = 0.038). Senior anaesthetists judged their contribution to patient well-being significantly higher than did their younger colleagues (P = 0.035). Although tiredness and subjective impairment of concentration abilities was high in senior anaesthetists after 24-h in-house on-call duty, performance assessed by psychometric testing does not support the hypothesis that senior colleague's performance cannot keep up with routine hospital shift work.

The collaborative group has created a draft egg product movement protocol, which calls for realistic, science-based contingency plans, biosecurity assessments, commodity risk assessments, and real-time reverse transcriptase-PCR testing to support the continuity of egg operations while also preventing and eradicating an HPAI outbreak. The work done by this group serves as an example of how industry, government, and academia can work together to achieve better preparedness in the event of an animal health emergency. In addition, in the event of an HPAI outbreak in domestic poultry, U.S. consumers will be assured that their egg products come from healthy chickens.

Many studies on the impact of psychosocial working conditions on health prove that psychosocial stress at work is an important risk factor endangering workers' health. Thus it should be constantly monitored like other work hazards. The paper presents a newly developed instrument for stress monitoring called the Psychosocial Working Conditions Questionnaire (PWC). Its structure is based on Robert Karasek's model of job stress (Karasek, 1979; Karasek & Theorell, 1990). It consists of 3 main scales Job Demands, Job Control, Social Support and 2 additional scales adapted from the Occupational Stress Questionnaire (Elo, Leppanen, Lindstrom, & Ropponen, 1992), Well-Being and Desired Changes. The study of 8 occupational groups (bank and insurance specialists, middle medical personnel, construction workers, shop assistants, government and self-government administration officers, computer scientists, public transport drivers, teachers, N = 3,669) indicates that PWC has satisfactory psychometrics parameters. Norms for the 8 groups were developed.

To compare radiation exposure of nurses when performing nursing tasks associated with interventional procedures depending on whether or not the nurses called out to the operator before approaching the patient. In a prospective study, 93 interventional radiology procedures were randomly divided into a call group and a no-call group; there were 50 procedures in the call group and 43 procedures in the no-call group. Two monitoring badges were used to calculate effective dose of nurses. In the call group, the nurse first told the operator she was going to approach the patient each time she was about to do so. In the no-call group, the nurse did not say anything to the operator when she was about to approach the patient. In all the nursing tasks, the equivalent dose at the umbilical level inside the lead apron was below the detectable limit. The equivalent dose at the sternal level outside the lead apron was 0.16 μSv ± 0.41 per procedure in the call group and 0.51 μSv ± 1.17 per procedure in the no-call group. The effective dose was 0.018 μSv ± 0.04 per procedure in the call group and 0.056 μSv ± 0.129 per procedure in the no-call group. The call group had a significantly lower radiation dose (P = .034). Radiation doses of nurses were lower in the group in which the nurse called to the operator before she approached the patient. Copyright © 2014 SIR. Published by Elsevier Inc. All rights reserved.

General patterns of managerial approaches to work motivation: Implications for rehabilitation professionals involved in occupational rehabilitation.

PubMed

Murphy, G C; Foreman, P

1993-03-01

Calls for rehabilitation counselors to learn more about the world of work have been recently repeated. The validity of these calls is suggested by a group of studies which indicate that the rehabilitation counseling literature has an established emphasis on matters of counseling and adjustment rather than on matters related to behavior in organizations. A survey of rehabilitation counsellors' beliefs about key topics in organizational behavior indicates that their beliefs are often discrepant with those of practicing managers and supervisors. A summary of dominant models of work motivation adopted by managerial workers is presented and some implications for occupational rehabilitation practice identified. Finally, some contemporary literature relevant to managerial approaches to employee motivation are identified and it is suggested that familiarity with this literature could assist rehabilitation practitioners move from a more narrow occupational rehabilitation role to a broader involvement in organizational life via the expansion of the disability management approach in work organizations.

Continuing professional development: issues raised by nurses and allied health professionals working in musculoskeletal settings.

PubMed

Haywood, Hannah; Pain, Helen; Ryan, Sarah; Adams, Jo

2013-09-01

Nurses and allied health professionals (AHPs) are required to evidence their engagement in continuing professional development (CPD) in order to retain their professional registration. Many challenges to CPD are reported, but little literature has explored pertinent CPD issues for clinicians with specialist roles or working in specialist services. No literature to date has explored the perceptions of CPD held by patients who receive these specialist services. Three focus groups and two conference calls were conducted with nurses, physiotherapists, podiatrists and occupational therapists who work in musculoskeletal (MSK) services; managers of these services; and people who use MSK services. These focus groups aimed: to explore the CPD needs and issues for this group of clinicians; to explore the perceptions of CPD held by people who have MSK conditions; and to compare the above with current literature to discern any factors specific to MSK settings. The focus groups and conference calls were audio-recorded. The recordings were coded by the researchers using a priori and inductive coding. The main issues discussed were: funding and time for CPD, providing examples of ways to provide CPD in spite of the challenges faced; that CPD needs changed with level of experience; initiatives by clinical specialists to reduce professional isolation; and future trends in CPD, including concerns about succession planning. The views of people with MSK conditions demonstrated an emphasis on communication skills that was seldom raised by managers and clinicians. Sufficient time, funding and provision of study leave were key to facilitating CPD activity for nurses and AHPs working in MSK services. People with MSK conditions particularly valued health professionals who combined good listening and communication skills with an attempt to understand what it was like to live with their condition.

Quint, J.; Handley, M.; Cummings, K.

1990-02-01

Between 1981-1986 a state-based occupational health telephone hotline received more than 8,000 inquiries on over 3,000 hazardous agents. Major caller groups were employees (37%), employers (20%), health care providers, primarily physicians (19%), government agencies (12%), and labor unions (6%). Employees were the fastest growing caller group. Callers inquired about general health hazards of chemicals (65%), the relation of symptoms to work (22%), and risks to pregnancy (13%).

2014-06-01

In this article, the authors examine the developmental continuity from prelinguistic communication to kindergarten age in language and working memory capacity. Following work outlining 6 groups of children with different trajectories of early communication development (ECD; Määttä, Laakso, Tolvanen, Ahonen, & Aro, 2012), the authors examined their later development by psychometric assessment. Ninety-one children first assessed at ages 12-21 months completed a battery of language and working memory tests at age 5;3 (years;months). Two of the ECD groups previously identified as being at risk for language difficulties continued to show weaker performance at follow-up. Seventy-nine percent of the children with compromised language skills at follow-up were identified on the basis of the ECD groups, but the number of false positives was high. The 2 at-risk groups also differed significantly from the typically developing groups in the measures tapping working memory capacity. In line with the dimensional view of language impairment, the accumulation of early delays predicted the amount of later difficulties; however, at the individual level, the prediction had rather low specificity. The results imply a strong link between language and working memory and call for further studies examining the early developmental interaction between language and memory.

Work began with epidemiological studies of all injuries in the local community in support of various experimental local interventions. An important element was the creation of 'surveillance systems' in healthcare. The work resulted in the establishment of a WHO Collaborating Centre and an international safety-building programme called 'Safe Communities'. In parallel, training at both master's and doctoral level and the building of a conference programme were embarked upon. The research group consists of three sections. Specific efforts are being made by some countries to address their own injury problems.

2015-01-01

It has been proved that emergency medical dispatch centers (EMDC) save lives by promoting an appropriate allocation of emergency medical service resources. Indeed, optimal dispatcher call duration is pivotal to reduce the time gap between the time a call is placed and the delivery of medical care. However, little is known about the impact of work shift configurations (i.e., work shift duration and work shift rotation throughout the day) and dispatcher call duration. Thus, the objective of our study was to assess the effect of work shift configurations on dispatcher call duration. During a 1-year study period, we analyzed the dispatcher call durations for medical and trauma calls during the 4 different work shift rotations (day, morning, evening, and night) and during the 10-hour work shift of each dispatcher in the EMDC of Nantes. We extracted dispatcher call durations from our advanced telephone system, configured with CC Pulse + (Genesys, Alcatel Lucent), and collected them in a custom designed database (Excel, Microsoft). Afterward, we analyzed these data using linear mixed effects models. During the study period, our EMDC received 408,077 calls. Globally, the mean dispatcher call duration was 107 ± 45 seconds. Based on multivariate linear mixed effects models, the dispatcher call duration was affected by night work shift and work shift duration greater than 8 hours, increasing it by about 10 ± 1 seconds and 4 ± 1 seconds, respectively (both p < 0.001). Our study showed that there was a statistically significant difference in dispatcher call duration over work shift rotation and duration, with longer durations seen over night shifts and shifts over 8 hours. While these differences are small and may not have clinical significance, they may have implications for EMDC efficiency.

A real-time computer model to assess resident work-hours scenarios.

PubMed

McDonald, Furman S; Ramakrishna, Gautam; Schultz, Henry J

2002-07-01

To accurately model residents' work hours and assess options to forthrightly meet Residency Review Committee-Internal Medicine (RRC-IM) requirements. The requirements limiting residents' work hours are clearly defined by the Accreditation Council for Graduate Medical Education (ACGME) and the RRC-IM: "When averaged over any four-week rotation or assignment, residents must not spend more than 80 hours per week in patient care duties."(1) The call for the profession to realistically address work-hours violations is of paramount importance.(2) Unfortunately, work hours are hard to calculate. We developed an electronic model of residents' work-hours scenarios using Microsoft Excel 97. This model allows the input of multiple parameters (i.e., call frequency, call position, days off, short-call, weeks per rotation, outpatient weeks, clinic day of the week, additional time due to clinic) and start and stop times for post-call, non-call, short-call, and weekend days. For each resident on a rotation, the model graphically demonstrates call schedules, plots clinic days, and portrays all possible and preferred days off. We tested the model for accuracy in several scenarios. For example, the model predicted average work hours of 85.1 hours per week for fourth-night-call rotations. This was compared with logs of actual work hours of 84.6 hours per week. Model accuracy for this scenario was 99.4% (95% CI 96.2%-100%). The model prospectively predicted work hours of 89.9 hours/week in the cardiac intensive care unit (CCU). Subsequent surveys found mean CCU work hours of 88, 1 hours per week. Model accuracy for this scenario was 98% (95% CI 93.2-100%). Thus validated, we then used the model to test proposed scenarios for complying with RRC-IM limits. The flexibility of the model allowed demonstration of the full range of work-hours scenarios in every rotation of our 36-month program. Demonstrations of status-quo work-hours scenarios were presented to faculty as well as real-time demonstrations of the feasibility, or unfeasibility, of their proposed solutions. The model clearly demonstrated that non-call (i.e., short-call) admissions without concomitant decreases in overnight call frequency resulted in substantial increases in total work hours. Attempts to "get the resident out" an hour or two earlier each day had negligible effects on total hours and were unrealistic paper solutions. For fourth-night-call rotations, the addition of a "golden weekend" (i.e., a fifth day off per month) was found to significantly reduce work hours. The electronic model allowed the development of creative schedules for previously third-night-call rotations that limit resident work hours without decreasing continuity of care by scheduling overnight call every sixth night alternating with sixth-night-short-call rotations. Our electronic model is sufficiently robust to accurately estimate work hours on multiple and varied rotations. This model clearly demonstrates that it is very difficult to meet the RRC-IM work-hours limitations under standard fourth-night-call schedules with only four days off per month. We are successfully using our model to test proposed alternative scenarios, to overcome faculty misconceptions about resident work-hours "solutions," and to make changes to our call schedules that both are realistic for residents to accomplish and truly diminish total resident work hours toward the requirements of the RRC-IM.

Prolonged sedentary time and physical activity in workplace and non-work contexts: a cross-sectional study of office, customer service and call centre employees

Background To examine sedentary time, prolonged sedentary bouts and physical activity in Australian employees from different workplace settings, within work and non-work contexts. Methods A convenience sample of 193 employees working in offices (131), call centres (36) and customer service (26) was recruited. Actigraph GT1M accelerometers were used to derive percentages of time spent sedentary (<100 counts per minute; cpm), in prolonged sedentary bouts (≥20 minutes or ≥30 minutes), light-intensity activity (100–1951 cpm) and moderate-to-vigorous physical activity (MVPA; ≥1952 cpm). Using mixed models adjusted for confounders, these were compared for: work days versus non-work days; work hours versus non-work hours (work days only); and, across workplace settings. Results Working hours were mostly spent sedentary (77.0%, 95%CI: 76.3, 77.6), with approximately half of this time accumulated in prolonged bouts of 20 minutes or more. There were significant (p<0.05) differences in all outcomes between workdays and non-work days, and, on workdays, between work- versus non-work hours. Results consistently showed “work” was more sedentary and had less light-intensity activity, than “non-work”. The period immediately after work appeared important for MVPA. There were significant (p<0.05) differences in all sedentary and activity outcomes occurring during work hours across the workplace settings. Call-centre workers were generally the most sedentary and least physically active at work; customer service workers were typically the least sedentary and the most active at work. Conclusion The workplace is a key setting for prolonged sedentary time, especially for some occupational groups, and the potential health risk burden attached requires investigation. Future workplace regulations and health promotion initiatives for sedentary occupations to reduce prolonged sitting time should be considered. PMID:23101767

A multidisciplinary group of students from the university and latter also from the high school was formed in 1988 with the objective to make them put in practice their knowledge in physics, chemistry and mathematics and engineering fields in experimental rocketry. The group was called "Grupo de Foguetes Experimentais", GFE. Since that time more than 150 students passed throw the group and now many of them are in the space arena. The benefits for students in a space hands-on project are many: More interest in their school subjects is gotten as they see an application for them; Interrelation attitudes are learned as space projects is a team activity; Responsibility is gained as each is responsible for a part of a critical mission project; Multidisciplinary and international experience is gotten as these are space project characteristics; Learn how to work in a high stress environment as use to be a project launch. This paper will cover the educational experiences gotten during these years and how some structured groups work. It is explained the objectives and how the group was formed. The group structure and the different phases that at each year the new team passes are described. It is shown the different activities that the group uses to do from scientific seminars, scientific club and international meetings to technical tours and assistance to rocket activities in regional schools. It is also explained the group outreach activities as some launches were covered by the media in more then 6 articles in newspaper and 7 television news. In 1999 as formed an official group called NATA, Núcleo de Atividades Aerospaciais within the Universidade Estadual de Londrina, UEL, by some GFE members and teachers from university. It is explained the first group project results.

Changes in the working environment will also influence the work of physicians. The greatest of these changes on the Finnish scale, the SOTE reform (the reform in social welfare and public health services), still lies ahead. Labor shortage, on-call duties and patient record systems providing little support to work add to the burden. In surveys related to psychosocial working conditions, physicians' greatest work load factors have been rush, forced working pace and poor communication despite the fact that, on average, they consider their working conditions to be good, frequently better than those of other professional groups, and are committed to carry on with their work until retirement age. Although psychic symptoms and sleep disturbances are common among physicians, there are fewer disability pensions due to e.g. depression among physicians than in other professional groups. Among the municipal professions, physicians have nearly the lowest rate of job absenteeism due to sickness. Challenges brought about by the changes in physician's work can be met with fair management, development of the social capital of the work community, organization of tasks and flexibility of working hours.

The purpose of this randomized, controlled trial was to examine the effects of a psychoeducational information website on improving work engagement among individual workers with low work engagement, where work engagement was measured as a secondary outcome. Participants were recruited from registered members of a web survey site in Japan. Participants who fulfilled the eligibility criteria were randomly allocated to intervention or control groups. Immediately after the baseline survey, the intervention group was invited to study a psychoeducational website called the "UTSMed," which provided general mental health literacy and cognitive behavioral skills. Work engagement was assessed by using the Utrecht Work Engagement Scale at baseline, 1-, and 4-month follow-ups for both intervention and control groups. An exploratory analysis was conducted for a subgroup with low (lower than the median scores) work engagement scores at baseline. A total of 1,236 workers completed the baseline survey. In the low work engagement subgroup, a total of 313 and 300 participants were allocated to an intervention and control group, respectively. In the high work engagement subgroup, 305 and 318 participants were allocated to an intervention and control group, respectively. The program showed a significant effect on work engagement (t = 1.98, P = 0.048) at the 4-month follow-up in the low work engagement subgroup, with a small effect size (d = 0.17). A web-based psychoeducation resource of mental health literacy and cognitive behavioral skills may be effective for improving work engagement among individual workers with low work engagement.

This study examined the relationship between on-call duty exposure (active and total on-call hours a month, number of calls per duty) and employees' experiences of being on-call (stress due to unpredictability, ability to relax during inactive on-call periods, restrictions during on-call duties, on-call work demands, and satisfaction with compensation for on-call duties) on the one hand and fatigue, strain-based and time-based work-home interference (WHI), and perceived on-call performance difficulties (PPD) on the other hand. Cross-sectional survey data were collected among a large heterogeneous sample of Dutch employees (N = 5437). The final sample consisted of 157 on-call workers (23-69 years, 71% males). Data were analyzed by means of hierarchical regression analyses (controlling for age and job characteristics). Differences in on-call work exposure were not systematically related to fatigue, WHI, and PPD (all p's >0.50). The experience of being on-call explained a medium proportion of the variation in fatigue and strain-based WHI and a medium to large proportion of the variation in time-based WHI and PPD over and above the control variables. Our results suggest that it is employees' experience of being on-call, especially the experience of stress due to the unpredictability, rather than the amount of exposure, that is related to fatigue, WHI, and perceived on-call performance difficulties.

Inbound Call Centers and Emotional Dissonance in the Job Demands – Resources Model

PubMed Central

Molino, Monica; Emanuel, Federica; Zito, Margherita; Ghislieri, Chiara; Colombo, Lara; Cortese, Claudio G.

2016-01-01

Background: Emotional labor, defined as the process of regulating feelings and expressions as part of the work role, is a major characteristic in call centers. In particular, interacting with customers, agents are required to show certain emotions that are considered acceptable by the organization, even though these emotions may be different from their true feelings. This kind of experience is defined as emotional dissonance and represents a feature of the job especially for call center inbound activities. Aim: The present study was aimed at investigating whether emotional dissonance mediates the relationship between job demands (workload and customer verbal aggression) and job resources (supervisor support, colleague support, and job autonomy) on the one hand, and, on the other, affective discomfort, using the job demands-resources model as a framework. The study also observed differences between two different types of inbound activities: customer assistance service (CA) and information service. Method: The study involved agents of an Italian Telecommunication Company, 352 of whom worked in the CA and 179 in the information service. The hypothesized model was tested across the two groups through multi-group structural equation modeling. Results: Analyses showed that CA agents experience greater customer verbal aggression and emotional dissonance than information service agents. Results also showed, only for the CA group, a full mediation of emotional dissonance between workload and affective discomfort, and a partial mediation of customer verbal aggression and job autonomy, and affective discomfort. Conclusion: This study’s findings contributed both to the emotional labor literature, investigating the mediational role of emotional dissonance in the job demands-resources model, and to call center literature, considering differences between two specific kinds of inbound activities. Suggestions for organizations and practitioners emerged in order to identify practical implications useful both to support employees in coping with emotional labor and to promote well-being in inbound call centers. In detail, results showed the need to improve training programs in order to enhance employees’ emotion regulation skills, and to introduce human resource practices aimed at clarifying emotional requirements of the job.

It has been argued that when people believe that their work is a calling, it can often be experienced as an intense and consuming passion with significant personal meaning. While callings have been demonstrated to have several positive outcomes for individuals, less is known about the potential downsides for those who experience work in this way. This study develops a multiple-meditation model proposing that, while the intensity of a calling has a positive direct effect on work-related vigor, it motivates people to work longer hours, which both directly and indirectly via longer work hours, limits their psychological detachment from work in the evenings. In turn, this process reduces sleep quality and morning vigor. Survey and diary data of 193 church ministers supported all hypotheses associated with this model. This implies that intense callings may limit the process of recovery from work experiences. The findings contribute to a more balanced theoretical understanding of callings.

On Constructing, Grouping and Using Topical Ontology for Semantic Matching

NASA Astrophysics Data System (ADS)

Tang, Yan; de Baer, Peter; Zhao, Gang; Meersman, Robert

An ontology topic is used to group concepts from different contexts (or even from different domain ontologies). This paper presents a pattern-driven modeling methodology for constructing and grouping topics in an ontology (PAD-ON methodology), which is used for matching similarities between competences in the human resource management (HRM) domain. The methodology is supported by a tool called PAD-ON. This paper demonstrates our recent achievement in the work from the EC Prolix project. The paper approach is applied to the training processes at British Telecom as the test bed.

As part of our effort to create an Integrated Academic Information Management System at Baylor College of Medicine, we are developing information technology to support the efforts of scientific work groups. Many of our ideas in this regard are embodied in a system called the Virtual Notebook which is intended to facilitate information sharing and management in such groups. Here we discuss the foundations of that system - a hypertext system that we have developed using a relational data base and the distributable interface the we have written in the X Window System.

The Working Group on Meteor Showers Nomenclature: a History, Current Status and a Call for Contributions

NASA Technical Reports Server (NTRS)

Jopek, T. J.; Jenniskens, P. M.

2011-01-01

During the IAU General Assembly in Rio de Janeiro in 2009, the members of Commission 22 established the Working Group on Meteor Shower Nomenclature, from what was formerly the Task Group on Meteor Shower Nomenclature. The Task Group had completed its mission to propose a first list of established meteor showers that could receive officially names. At the business meeting of Commission 22 the list of 64 established showers was approved and consequently officially accepted by the IAU. A two-step process is adopted for showers to receive an official name from the IAU: i) before publication, all new showers discussed in the literature are first added to the Working List of Meteor Showers, thereby receiving a unique name, IAU number and three-letter code; ii) all showers which come up to the verification criterion are selected for inclusion in the List of Established Meteor Showers, before being officially named at the next IAU General Assembly.

Bell miner provisioning calls are more similar among relatives and are used by helpers at the nest to bias their effort towards kin

PubMed Central

McDonald, Paul G.; Wright, Jonathan

2011-01-01

Kin selection predicts that helpers in cooperative systems should preferentially aid relatives to maximize fitness. In family-based groups, this can be accomplished simply by assisting all group members. In more complex societies, where large numbers of kin and non-kin regularly interact, more sophisticated kin-recognition mechanisms are needed. Bell miners (Manorina melanophrys) are just such a system where individuals regularly interact with both kin and non-kin within large colonies. Despite this complexity, individual helpers of both sexes facultatively work harder when provisioning the young of closer genetic relatedness. We investigated the mechanism by which such adaptive discrimination occurs by assessing genetic kinship influences on the structure of more than 1900 provisioning vocalizations of 185 miners. These ‘mew’ calls showed a significant, positive linear increase in call similarity with increasing genetic relatedness, most especially in comparisons between male helpers and the breeding male. Furthermore, individual helping effort was more heavily influenced by call similarity to breeding males than to genetic relatedness, as predicted if call similarity is indeed the rule-of-thumb used to discriminate kin in this system. Individual mew call structure appeared to be inflexible and innate, providing an effective mechanism by which helpers can assess their relatedness to any individual. This provides, to our knowledge, the first example of a mechanism for fine-scale kin discrimination in a complex avian society. PMID:21450738

Health issues amongst call center employees, an emerging occupational group in India.

Raja, Jeyapal Dinesh; Bhasin, Sanjiv Kumar

2014-07-01

Call center sector in India is a relatively new industry and one of the fastest growing sectors driving employment and growth in modern India today. While employment in the business process outsourcing (BPO) sector has meant that young adults are reaching their career milestones and financial goals much earlier than before, surveys and anecdotal evidence show that workers in the BPO sector experience high levels of stress and its related disorders, primarily due to its contemporary work settings. Safeguarding the health of youngsters employed in this new, growing economy becomes an occupational health challenge to public health specialists.

Between 1981-1986 a state-based occupational health telephone hotline received more than 8,000 inquiries on over 3,000 hazardous agents. Major caller groups were employees (37%), employers (20%), health care providers, primarily physicians (19%), government agencies (12%), and labor unions (6%). Employees were the fastest growing caller group. Callers inquired about general health hazards of chemicals (65%), the relation of symptoms to work (22%), and risks to pregnancy (13%). PMID:2297067

The Role and Reprocessing of Attitudes in Fostering Employee Work Happiness: An Intervention Study.

PubMed

Williams, Paige; Kern, Margaret L; Waters, Lea

2017-01-01

This intervention study examines the iterative reprocessing of explicit and implicit attitudes as the process underlying associations between positive employee attitudes (PsyCap), perception of positive organization culture (organizational virtuousness, OV), and work happiness. Using a quasi-experimental design, a group of school staff ( N = 69) completed surveys at three time points. After the first assessment, the treatment group ( n = 51) completed a positive psychology training intervention. Results suggest that employee PsyCap, OV, and work happiness are associated with one another through both implicit and explicit attitudes. Further, the Iterative-Reprocessing Model of attitudes (IRM) provides some insights into the processes underlying these associations. By examining the role and processes through which explicit and implicit attitudes relate to wellbeing at work, the study integrates theories on attitudes, positive organizational scholarship, positive organizational behavior and positive education. It is one of the first studies to apply the theory of the IRM to explain associations amongst PsyCap, OV and work happiness, and to test the IRM theory in a field-based setting. In applying attitude theory to wellbeing research, this study provides insights to mechanisms underlying workplace wellbeing that have not been previously examined and in doing so responds to calls for researchers to learn more about the mechanisms underlying wellbeing interventions. Further, it highlights the need to understand subconscious processes in future wellbeing research and to include implicit measures in positive psychology interventions measurement programs. Practically, this research calls attention to the importance of developing both the positive attitudes of employees and the organizational culture in developing employee work happiness.

Objectives. This study examined the relationship between on-call duty exposure (active and total on-call hours a month, number of calls per duty) and employees' experiences of being on-call (stress due to unpredictability, ability to relax during inactive on-call periods, restrictions during on-call duties, on-call work demands, and satisfaction with compensation for on-call duties) on the one hand and fatigue, strain-based and time-based work-home interference (WHI), and perceived on-call performance difficulties (PPD) on the other hand. Methods. Cross-sectional survey data were collected among a large heterogeneous sample of Dutch employees (N = 5437). The final sample consisted of 157 on-call workers (23–69 years, 71% males). Data were analyzed by means of hierarchical regression analyses (controlling for age and job characteristics). Results. Differences in on-call work exposure were not systematically related to fatigue, WHI, and PPD (all p's >0.50). The experience of being on-call explained a medium proportion of the variation in fatigue and strain-based WHI and a medium to large proportion of the variation in time-based WHI and PPD over and above the control variables. Conclusions. Our results suggest that it is employees' experience of being on-call, especially the experience of stress due to the unpredictability, rather than the amount of exposure, that is related to fatigue, WHI, and perceived on-call performance difficulties.

The introduction of the shift system in response to the European Working Time Directive has had an enormous impact on the running of neurosurgical units in the UK. This study seeks to establish what provisions are currently in place for out of hours cover and what has been the effect of the introduction of shifts in three main areas: patient safety, training and 'work/life balance'. The on-call registrar at each UK neurosurgical unit was contacted by telephone. Data regarding current emergency provision were sought. Registrars who had worked both on-calls and the shift system during their career as a neurosurgical registrar were asked to make a comparison. Data were collected from all 33 UK units. Twenty-two still use a traditional 24-h on-call system. Twenty-one on-call rotas were classed as non-resident although 12/21 of those officially on non-resident rotas were in fact resident whilst on call. Twenty-two registrars had worked both systems as a neurosurgical registrar. Twenty-one (95.45%) felt that traditional on-calls gave better clinical exposure. Twenty-one (95.45%) felt that on-calls allowed the provision of better patient care. Nineteen (86.36%) felt that on-calls were safer. Thirteen (59.09%) reported that they were more tired when doing shift work than on-calls. Fourteen (63.63%) found that the on-call system gives more useful spare time and more time to deal with family commitments. Current neurosurgery registrars feel the shift system is less safe, harmful to training and worse in terms of work/life balance. More than one-third of units are claiming to have non-resident on-call systems in order to appear compliant with EWTD when registrars are in fact resident.

Treatment of vitiligo with narrowband ultraviolet B light (NBUVB) is an important component of the current standard of care. However, there are no consistent guidelines regarding the dosing and administration of NBUVB in vitiligo, reflected by varied treatment practices around the world. To create phototherapy recommendations to facilitate clinical management and identify areas requiring future research. The Vitiligo Working Group (VWG) Phototherapy Committee addressed 19 questions regarding the administration of phototherapy over 3 conference calls. Members of the Photomedicine Society and a group of phototherapy experts were surveyed regarding their phototherapy practices. Based on comparison and analysis of survey results, expert opinion, and discussion held during conference calls, expert recommendations for the administration of NBUVB phototherapy in vitiligo were created. There were several areas that required further research before final recommendations could be made. In addition, no standardized methodology was used during literature review and to assess the strength of evidence during the development of these recommendations. This set of expert recommendations by the VWG is based on the prescribing practices of phototherapy experts from around the world to create a unified, broadly applicable set of recommendations on the use of NBUVB in vitiligo.

A Call to Action: Building a Translational Inclusion Team Science in Physical Activity, Nutrition, and Obesity Management for Children with Disabilities.

Rimmer, James H; Vanderbom, Kerri A

2016-01-01

The growing evidence base of childhood obesity prevention and treatment programs do not adequately consider how to adapt these programs for children with disabilities. We propose a Call to Action for health researchers who conduct studies focused on the general population (i.e., without a disability) to work closely with disability researchers to adapt their programs (e.g., obesity management, increased physical activity, and caregiver training in diet and nutrition) to be relevant to both groups. We refer to this approach as inclusion team science. The hope for this Call to Action is that there will be greater synergy between researchers who have high levels of expertise in a specialty area of health (but little or no knowledge of how to adapt their program for children with disabilities) to work more closely with researchers who have a high level of expertise in adapting evidence-based health promotion recommendations and strategies for children with disabilities. Together, these two areas of expertise will lead to inclusive physical activity and nutrition programs for all children.

For more than twenty years a dynamic group of doctors has on a voluntary basis been on call for their colleagues experiencing crisis reactions related to work and personal life. Consultancies are anonymous; only a few data are registered in order to gather insight into the reasons for seeking assistance. The majority of contacts now seem to be work-related stress, conflicts with colleagues, family problems, illness and abuse. Patient claims and a bad press are not as frequent as they used to be.

Exploration of the facilitators of and barriers to work engagement in nursing.

Freeney, Yseult M; Tiernan, Joan

2009-12-01

Engagement is couched as the opposite to burnout and while there have been numerous studies that have supported the relationship between organizational antecedents and employee engagement, nurse engagement is still inadequately understood. Recent papers in the nursing literature have called for more research on this construct to be conducted with nurses so that nurse leaders can be better informed about the impact of engagement on outcomes for the organization. To explore nurses' experiences of their work environments and to reveal factors in the workplace that may facilitate or act as barriers to nurse engagement. A qualitative methodology was employed with the data from focus groups with a total of 20 nurses working in both general and psychiatric nursing. Facilitators of and barriers to engagement center around six areas of organizational life, namely; workload, control, reward, fairness, community and values. Interventions aimed at fostering engagement are called for and through future research in the area of engagement, it is believed that nurses will gain more positive experiences from their work and subsequently a greater sense of well-being.

Surgeon distress as calibrated by hours worked and nights on call.

2010-11-01

The relationships of working hours and nights on call per week with various parameters of distress among practicing surgeons have not been previously examined in detail. More than 7,900 members of the American College of Surgeons responded to an anonymous, cross-sectional survey. The survey included self-assessment of their practice setting, a validated depression screening tool, and standardized assessments of burnout and quality of life. There was a clear gradient between hours and burnout, with the prevalence of burnout ranging from 30% for surgeons working <60 hours/week, 44% for 60 to 80 hours/week, and 50% for those working >80 hours/week (p < 0.001). When correlated with number of nights on call, burnout exhibited a threshold effect at ≥2 nights on call/week (≤1 nights on call/week, 30%; ≥2 nights on call/week, 44% to 46%; p < 0.0001). Screening positive for depression rate also correlated strongly with hours and nights on call (both p < 0.0001). Those who worked >80 hours/week reported a higher rate of medical errors compared with those who worked <60 hours/week (10.7% versus 6.9%; p < 0.001), and were twice as likely to attribute the error to burnout (20.1% versus 8.9%; p = 0.001). Not surprisingly, work and home conflicts were higher among surgeons who worked longer hours or had ≥2 nights on call. A significantly higher proportion of surgeons who worked >80 hours/week or had >2 nights on call/week would not become a surgeon again (p < 0.0001). Number of hours worked and nights on call per week appear to have a substantial impact on surgeons, both professionally and personally. These factors are strongly related to burnout, depression, career satisfaction, and work and home conflicts. Copyright © 2010 American College of Surgeons. Published by Elsevier Inc.

Objective: The purpose of this randomized, controlled trial was to examine the effects of a psychoeducational information website on improving work engagement among individual workers with low work engagement, where work engagement was measured as a secondary outcome. Methods: Participants were recruited from registered members of a web survey site in Japan. Participants who fulfilled the eligibility criteria were randomly allocated to intervention or control groups. Immediately after the baseline survey, the intervention group was invited to study a psychoeducational website called the "UTSMed," which provided general mental health literacy and cognitive behavioral skills. Work engagement was assessed by using the Utrecht Work Engagement Scale at baseline, 1-, and 4-month follow-ups for both intervention and control groups. An exploratory analysis was conducted for a subgroup with low (lower than the median scores) work engagement scores at baseline. Results: A total of 1,236 workers completed the baseline survey. In the low work engagement subgroup, a total of 313 and 300 participants were allocated to an intervention and control group, respectively. In the high work engagement subgroup, 305 and 318 participants were allocated to an intervention and control group, respectively. The program showed a significant effect on work engagement (t = 1.98, P = 0.048) at the 4-month follow-up in the low work engagement subgroup, with a small effect size (d = 0.17). Conclusion: A web-based psychoeducation resource of mental health literacy and cognitive behavioral skills may be effective for improving work engagement among individual workers with low work engagement.

2011-01-01

This study sought to investigate the relationship between cell phone conversation type and dangerous driving behaviors. It was hypothesized that more emotional phone conversations engaged in while driving would produce greater frequencies of dangerous driving behaviors in a simulated environment than more mundane conversation or no phone conversation at all. Participants were semi-randomly assigned to one of three conditions: (1) no call, (2) mundane call, and, (3) emotional call. While driving in a simulated environment, participants in the experimental groups received a phone call from a research confederate who either engaged them in innocuous conversation (mundane call) or arguing the opposite position of a deeply held belief of the participant (emotional call). Participants in the no call and mundane call groups differed significantly only on percent time spent speeding and center line crossings, though the mundane call group consistently engaged in more of all dangerous driving behaviors than did the no call participants. Participants in the emotional call group engaged in significantly more dangerous driving behaviors than participants in both the no call and mundane call groups, with the exception of traffic light infractions, where there were no significant group differences. Though there is need for replication, the authors concluded that whereas talking on a cell phone while driving is risky to begin with, having emotionally intense conversations is considerably more dangerous.

To study the effects of fatigue on general surgery residents' performance on the da Vinci Skills Simulator (dVSS). 15 General Surgery residents from various postgraduate training years (PGY2, PGY3, PGY4, and PGY5) performed 5 simulation tasks on the dVSS as recommended by the Robotic Training Network (RTN). The General Surgery residents had no prior experience with the dVSS. Participants were assigned to either the Pre-call group or Post-call group based on call schedule. As a measure of subjective fatigue, residents were given the Epworth Sleepiness Scale (ESS) prior to their dVSS testing. The dVSS MScore™ software recorded various metrics (Objective Structured Assessment of Technical Skills, OSATS) that were used to evaluate the performance of each resident to compare the robotic simulation proficiency between the Pre-call and Post-call groups. Six general surgery residents were stratified into the Pre-call group and nine into the Post-call group. These residents were also stratified into Fatigued (10) or Nonfatigued (5) groups, as determined by their reported ESS scores. A statistically significant difference was found between the Pre-call and Post-call reported sleep hours (p = 0.036). There was no statistically significant difference between the Pre-call and Post-call groups or between the Fatigued and Nonfatigued groups in time to complete exercise, number of attempts, and high MScore™ score. Despite variation in fatigue levels, there was no effect on the acquisition of robotic simulator skills.

Which stroke symptoms prompt a 911 call? A population-based study.

Many studies show that a major barrier to short-term treatment of stroke is patient or bystander delay in responding to stroke symptoms. Most studies have found that less than half of stroke/transient ischemic attack (TIA) events result in a 911 call. We sought to determine which symptoms prompt the public to call 911. A population of 1.3 million within a 5-county region was screened for TIA and all strokes in 1999 using all local hospital International Classification of Diseases, Ninth Edition, codes for stroke (430-436) during 1999. Documented stroke symptoms were abstracted from the medical record. Symptoms were grouped as weakness, numbness, speech/language, confusion/decreased level of consciousness, headache, visual changes, and dizziness/vertigo/coordination. Cases included in this analysis had their strokes at home or work and presented to an emergency department. Logistic regression assessed which symptoms predicted a 911 call, adjusting for age, race, sex, prior stroke, baseline disability, overall stroke severity, home vs work, and stroke subtype. Two thousand nine hundred seventy-five stroke/TIA patients met inclusion criteria, of whom 40% used emergency medical services. After adjustment, symptoms that increased odds of a 911 call were weakness, confusion/decreased level of consciousness, speech/language, and dizziness/coordination/vertigo. Numbness was less likely to result in a 911 call as were visual changes. The presence of headache was not associated with the decision to call 911. The public appears to respond differently based on the type of stroke symptom, independent of overall severity. Public awareness messages regarding stroke warning signs should be designed with this in mind. Copyright (c) 2010 Elsevier Inc. All rights reserved.

Ecological and Behavioural Factors Influencing Territorial Call Rates for the Bolivian Titi Monkeys, Plecturocebus modestus and Plecturocebus olallae.

PubMed

Martinez, Jesus; Wallace, Robert B

2016-01-01

Primate territorial calls have been used to locate groups in censuses. Daily variations in call rates are a potential source of error in these studies. To obtain more accurate estimations of population density it is necessary to determine how much variation there is in group call rates and to identify the factors that influence them. We present data on the emission of territorial calls by two threatened and endemic titi monkeys in Bolivia: Plecturocebus olallae and P. modestus. We found interspecific differences in daily call rates (52% P. modestus and 33% P. olallae). Groups inhabiting more continuous forests vocalized more frequently than groups in fragmented forests, which might be linked to the higher abundance of groups in less fragmented forests. We found seasonal differences in call rates between species, with more frequent calling in P. modestus during the dry season, while P. olallae called more frequently in the rainy season. The study groups emitted territorial calls mostly from the central zones of their territories, suggesting they do not face intense spatial competition with neighbouring groups. Our results improve the general ecological knowledge on P. olallae and P. modestus, and can also be used to improve population abundance studies and ongoing conservation efforts. © 2016 S.

Nelson, C S; Dell'Angela, K; Jellish, W S; Brown, I E; Skaredoff, M

1995-10-01

The effects of sleep deprivation on medical personnel have received much attention. This study evaluates the effects of sleep loss on divergent-thinking (creative or innovative) processes as measured by the Torrance Test of Creative Thinking (TTCT). Anesthesia residents who had approximately 30 minutes sleep while being on-call were evaluated. These physicians had similar caffeine and nicotine consumption before and after the test. The results reported here demonstrate that postcall residents had TTCT scores that were appreciably below those scores of rested residents. Postcall verbal fluency was less among the on-call group than among the rested group (94.0 +/- 9.7 vs 101.8 +/- 9.8) as was figural originality (89.9 +/- 22.1 vs 113.3 +/- 20.3). These study results suggest that sleep deprivation affects divergent, or creative, thinking. Divergent-thinking processes are usually innovative and are used during complex problem-solving tasks. Further studies are needed on the effects of sleep deprivation. This information can then be used to help improve residents' working conditions and patient care.

Patterns of call communication between group-housed zebra finches change during the breeding cycle.

2015-10-06

Vocal signals such as calls play a crucial role for survival and successful reproduction, especially in group-living animals. However, call interactions and call dynamics within groups remain largely unexplored because their relation to relevant contexts or life-history stages could not be studied with individual-level resolution. Using on-bird microphone transmitters, we recorded the vocalisations of individual zebra finches (Taeniopygia guttata) behaving freely in social groups, while females and males previously unknown to each other passed through different stages of the breeding cycle. As birds formed pairs and shifted their reproductive status, their call repertoire composition changed. The recordings revealed that calls occurred non-randomly in fine-tuned vocal interactions and decreased within groups while pair-specific patterns emerged. Call-type combinations of vocal interactions changed within pairs and were associated with successful egg-laying, highlighting a potential fitness relevance of calling dynamics in communication systems.

Support groups for children in alternate care: a largely untapped therapeutic resource.

PubMed

Mellor, D; Storer, S

1995-01-01

Children in alternate care often have adjustment problems that manifest in various aspects of their lives. Individual therapy is often assumed to be the desired intervention, but resources seldom permit one-to-one therapy for these disturbances. The authors argue that groupwork should be considered as a possible treatment of choice. Not only is it likely to be more economical than individual therapy, it has the inherent advantage of telling children in care that they are not alone, and that other children have similar experiences and feelings. It also allows them to develop their own support network. Such groups appear to have been underutilized in work with children in out-of-home care. This article describes such a group and its outcome. Various techniques were developed to achieve specified aims. The techniques appeared to be successful. Further work on such groups and more specific evaluation is called for.

2015 Summary Report on Industrial and Regulatory Engagement Activities

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

Thomas, Kenneth David

2015-09-01

The Advanced Instrumentation, Information, and Control (II&C) Systems Technologies pathway of the Light Water Reactor Sustainability(LWRS) Program conducts a vigorous engagement strategy with the U.S. nuclear power industry, including the nuclear operating companies, major support organizations, the Nuclear Regulatory Commission (NRC), and suppliers. The goal of this engagement strategy is to develop a shared vision and common understanding across the nuclear industry of the need for II&C modernization, the performance improvement that can be obtained, and the opportunities for collaboration to enact this vision. The primary means of engaging the nuclear operating companies is through a Utility Working Group (UWG),more » composed of utility representatives that participate in formal meetings and bi-monthly phone calls to provide input on nuclear plant needs and priorities for II&C technologies. Two working groups were initiated during FY 2015 to provide a means for UWG members to focus on particular technologies of interest. The Outage Improvement Working Group consists of eight utilities that participate in periodic conference calls and have access to a share-point web page for acccess to project materials developed in the Advanced Outage Control Center pilot project. In the area of computer-based procedures and automated work packages, the II&C Pathway has worked with the Nuclear Information Technology Strategic Leadership (NITSL) to set up a monthly conference call with interested utility members to discuss various aspects of mobile worker technologies. Twenty one technical and project reports were delivered to the UWG during FY 2015, reflecting the work of the II&C Pathway pilot projects during the year. Distribution of these reports is one of the primary means of transferring to the nuclear industry the knowledge and experience gained during the development of advanced II&C technologies in support of LWR sustainability. Site visits to discuss pilot project activities and future plans were made to Arizona Public Service, Exelon, Duke Energy, Pacific Gas & Electric, SCANA, Southern Nuclear, South Texas Project, STARS Alliance, Tennessee Valley Authority, and Xcel. Discussions were also held on the pathway goals and activities with major industry support organizations during FY 2102, including the Institute of Nuclear Power Operations (INPO), the Nuclear Information Technology Strategic Leadership (NITSL), the Nuclear Energy Institute (NEI), and the Electric Power Research Institute. The Advanced II&C Pathway work was presented at five major industry conferences and Informal discussions were held with key NRC managers at industry conferences. In addition, discussions were held with NRC senior managers on digital regulatory issues through participation on the NEI Digital I&C Working Group. Meetings were held with major industry suppliers and consultants, to explore opportunities for collaboration and to provide a means of pilot project technology transfer. In the international area, discussions were held with Electricite’ de France (EdF) concerning possible collaboration in the area NPP configuration control using intelligent wireless devices.« less

Hydrogen Ordering in Hexagonal Intermetallic AB5 Type Compounds

NASA Astrophysics Data System (ADS)

Sikora, W.; Kuna, A.

2008-04-01

Intermetallic compounds AB5 type (A = rare-earth atoms, B = transition metal) are known to store reversibly large amounts of hydrogen and as that are discussed in this work. It was shown that the alloy cycling stability can be significantly improved by employing the so-called non-stoichiometric compounds AB5+x and that is why analysis of change of structure turned out to be interesting. A tendency for ordering of hydrogen atoms is one of the most intriguing problems for the unsaturated hydrides. The symmetry analysis method in the frame of the theory of space group and their representation gives opportunity to find all possible transformations of the parent structure. In this work symmetry analysis method was applied for AB5+x structure type (P6/mmm parent symmetry space group). There were investigated all possible ordering types and accompanying atom displacements in positions 1a, 2c, 3g (fully occupied in stoichiometric compounds AB5), in positions 2e, 6l (where atom B could appear in non-stoichiometric compounds) and also 4h, 6m, 6k, 12n, 12o, which could be partly occupied by hydrogen as a result of hydrides. An analysis was carried out of all possible structures of lower symmetry, following from P6/mmm for we k=(0, 0, 0). Also the way of getting the structure described by the P63mc space group with double cell along the z-axiswe k=(0, 0, 0.5), as it is suggested in the work of Latroche et al. is discussed by the symmetry analysis. The analysis was obtained by computer program MODY. The program calculates the so-called basis vectors of irreducible representations of a given symmetry group, which can be used for calculation of possible ordering modes.

Group Dynamics as a Critical Component of Successful Space Exploration: Conceptual Theory and Insights from the Biosphere 2 Closure Experiment

NASA Astrophysics Data System (ADS)

Nelson, Mark; Allen, John P.

As space exploration and eventually habitation achieves longer durations, successfully managing group dynamics of small, physically isolated groups will become vital. The paper summarizes important underlying research and conceptual theory and how these manifested in a well-documented example: the closure experiments of Biosphere 2. Key research breakthroughs in discerning the operation of small human groups comes from the pioneering work of W.R. Bion. He discovered two competing modalities of behavior. The first is the “task-oriented” or work group governed by shared acceptance of goals, reality-thinking in relation to time, resources and rational, and intelligent management of challenges presented. The opposing, usually unconscious, modality is what Bion called the “basic-assumption” group and alternates between three “group animal” groups: dependency/kill the leader; fight/flight and pairing. If not dealt with, these dynamics work to undermine and defeat the conscious task group’s goal achievement. The paper discusses crew training and selection, various approaches to structuring the work and hierarchy of the group, the importance of contact with a larger population through electronic communication and dealing with the “us-them” syndrome frequently observed between crew and Mission Control. The experience of the first two year closure of Biosphere 2 is drawn on in new ways to illustrate vicissitudes and management of group dynamics especially as both the inside team of biospherians and key members of Mission Control had training in working with group dynamics. Insights from that experience may help mission planning so that future groups in space cope successfully with inherent group dynamics challenges that arise.

Non-song social call bouts of migrating humpback whales

The use of stereotyped calls within structured bouts has been described for a number of species and may increase the information potential of call repertoires. Humpback whales produce a repertoire of social calls, although little is known about the complexity or function of these calls. In this study, digital acoustic tag recordings were used to investigate social call use within bouts, the use of bouts across different social contexts, and whether particular call type combinations were favored. Call order within bouts was investigated using call transition frequencies and information theory techniques. Call bouts were defined through analysis of inter-call intervals, as any calls within 3.9 s of each other. Bouts were produced significantly more when new whales joined a group compared to groups that did not change membership, and in groups containing multiple adults escorting a female and calf compared to adult only groups. Although social calls tended to be produced in bouts, there were few repeated bout types. However, the order in which most call types were produced within bouts was non-random and dependent on the preceding call type. These bouts appear to be at least partially governed by rules for how individual components are combined. PMID:26093396

Psychologists have repeatedly shown that a single statistical factor--often called "general intelligence"--emerges from the correlations among people's performance on a wide variety of cognitive tasks. But no one has systematically examined whether a similar kind of "collective intelligence" exists for groups of people. In two studies with 699 people, working in groups of two to five, we find converging evidence of a general collective intelligence factor that explains a group's performance on a wide variety of tasks. This "c factor" is not strongly correlated with the average or maximum individual intelligence of group members but is correlated with the average social sensitivity of group members, the equality in distribution of conversational turn-taking, and the proportion of females in the group.

Childhood acute lymphoblastic leukemia (cALL) is the most prevalent form of cancer in children. Due to advances in treatment and therapy, young cALL subjects now achieve a 90% survival rate. However, this tremendous advance does not come without consequence since ~2/3 of cALL survivors are affected by long-term and late, severe complications. Although the metabolic syndrome is a very serious sequel of cALL, the mechanisms remain undefined. It is also surprising to note that the mitochondrion, a central organelle in metabolic functions and the main cellular energy generator, have not yet been explored. To determine whether cALL survivors exhibit impairments in their mitochondrial functions and proteomic profiling in relationship with metabolic disorders in cALL survivors compared to healthy controls. Anthropometric measures, metabolic characteristics and lipid profiles were assessed, mitochondria isolated from peripheral blood mononuclear cells, and proteomic analyzed. Our data demonstrated that metabolically Unhealthy survivors exhibited several metabolic syndrome components (e.g. overweight, insulin resistance, dyslipidemia, inflammation) whereas Healthy cALL survivors resemble the Controls. In line with these abnormalities, functional experiments in these subjects revealed a significant decrease in the protein expression of mitochondrial antioxidant superoxide dismutase, PGC1-α transcription factor (a key modulator of mitochondrion biogenesis), and an increase in pro-apoptotic cytochrome c. Proteomic analysis of mitochondria by mass spectrometry revealed changes in the regulation of proteins related to inflammation, apoptosis, energy production, redox and antioxidant activity, fatty acid β-oxidation, protein transport and metabolism, and signalling pathways between groups. Through the use of proteomic analysis, our work demonstrated a number of significant alterations in protein expression in mitochondria of cALL survivors, especially the metabolically Unhealthy survivor group. Further investigation of these proteins may help delineate the mechanisms by which mitochondrial dysfunctions exert cardiometabolic derangements in cALL survivors. Copyright © 2018.

Meaningful call combinations and compositional processing in the southern pied babbler

PubMed Central

Engesser, Sabrina; Ridley, Amanda R.; Townsend, Simon W.

2016-01-01

Language’s expressive power is largely attributable to its compositionality: meaningful words are combined into larger/higher-order structures with derived meaning. Despite its importance, little is known regarding the evolutionary origins and emergence of this syntactic ability. Although previous research has shown a rudimentary capability to combine meaningful calls in primates, because of a scarcity of comparative data, it is unclear to what extent analog forms might also exist outside of primates. Here, we address this ambiguity and provide evidence for rudimentary compositionality in the discrete vocal system of a social passerine, the pied babbler (Turdoides bicolor). Natural observations and predator presentations revealed that babblers produce acoustically distinct alert calls in response to close, low-urgency threats and recruitment calls when recruiting group members during locomotion. On encountering terrestrial predators, both vocalizations are combined into a “mobbing sequence,” potentially to recruit group members in a dangerous situation. To investigate whether babblers process the sequence in a compositional way, we conducted systematic experiments, playing back the individual calls in isolation as well as naturally occurring and artificial sequences. Babblers reacted most strongly to mobbing sequence playbacks, showing a greater attentiveness and a quicker approach to the loudspeaker, compared with individual calls or control sequences. We conclude that the sequence constitutes a compositional structure, communicating information on both the context and the requested action. Our work supports previous research suggesting combinatoriality as a viable mechanism to increase communicative output and indicates that the ability to combine and process meaningful vocal structures, a basic syntax, may be more widespread than previously thought.

On-call work and physicians' turnover intention: the moderating effect of job strain.

PubMed

Heponiemi, Tarja; Presseau, Justin; Elovainio, Marko

2016-01-01

Physician shortage and turnover are major problems worldwide. On-call duties may be among the risk factors of high turnover rates among physicians. We investigated whether having on-call duties is associated with physicians' turnover intention and whether job strain variables moderate this association. The present study was a cross-sectional questionnaire study among 3324 (61.6% women) Finnish physicians. The analyses were conducted using analyses of covariance adjusted for age, gender, response format, specialization status and employment sector. The results showed that job strain moderated the association between being on-call and turnover intention. The highest levels of turnover intention were among those who had on-call duties and high level of job strain characterized by high demands and low control opportunities. The lowest levels of turnover intention were among those who were not on-call and who had low strain involving low demands and high control. Also, job demands moderated the association between being on-call and turnover intention; turnover intention levels were higher among those with on-call duties and high demands than those being on-call and low demands. To conclude, working on-call was related to physicians' turnover intention particularly in those with high job strain. Health care organizations should focus more attention on working arrangements and scheduling of on-call work, provide a suitable working pace and implement means to increase physicians' participation and control over their job.

Calling and life satisfaction: it's not about having it, it's about living it.

PubMed

Duffy, Ryan D; Allan, Blake A; Autin, Kelsey L; Bott, Elizabeth M

2013-01-01

The present study examined the relation of career calling to life satisfaction among a diverse sample of 553 working adults, with a specific focus on the distinction between perceiving a calling (sensing a calling to a career) and living a calling (actualizing one's calling in one's current career). As hypothesized, the relation of perceiving a calling to life satisfaction was fully mediated by living a calling. On the basis of this finding, a structural equation model was tested to examine possible mediators between living a calling and life satisfaction. As hypothesized, the relation of living a calling to life satisfaction was partially mediated by job satisfaction and life meaning, and the link between living a calling and job satisfaction was mediated by work meaning and career commitment. Modifications of the model also revealed that the link of living a calling to life meaning was mediated by work meaning. Implications for research and practice are discussed.

Effects of night-time on-call work on heart rate variability before bed and sleep quality in visiting nurses.

Kikuchi, Yukiko; Ishii, Noriko; Kodama, Hideya

2018-05-28

In Japan, many visiting nurses work carrying cell phones to respond to calls from users even at night (on-call work). The purpose of this study was to investigate whether on-call work affected heart rate variability (HRV) before bed and decreased sleep quality in visiting nurses even if their sleep was not interrupted due to actual calls. Thirty-one visiting nurses (mean age, 49.8 years; standard deviation, 6.3 years) were asked to record their 2.5-min resting HRV before bed, and to undergo one-channel sleep electroencephalography (EEG) and subjective sleep evaluations upon waking (Oguri, Shirakawa, and Azumi Sleep Inventory) at home for 4-5 consecutive days, including both on-call and non-on-call days. Paired data sets of outcome measures, including HRV parameters, sleep macrostructure variables, and subjective sleep quality scores between on-call and non-on-call days were compared; the most recent measurements for each category were used for each subject. There were no differences in HRV measures and objective sleep EEG variables. A significant increase in "sleepiness on rising" and a decrease in "feeling refreshed" were observed on on-call days (P = 0.019 and 0.021, respectively), and younger subjects (≤ 51 years old) demonstrated a significant reduction in "sleepiness on rising" (significant interaction effect, P = 0.029). Adverse effects of on-call work on sleep quality in most visiting nurses are thought to be subjective, and relatively young nurses tend to notice a decrease in sleep quality. On-call work itself does not appear to be a substantial stressor that could affect HRV and sleep structure.

From Data-Sharing to Model-Sharing: SCEC and the Development of Earthquake System Science (Invited)

NASA Astrophysics Data System (ADS)

Jordan, T. H.

2009-12-01

Earthquake system science seeks to construct system-level models of earthquake phenomena and use them to predict emergent seismic behavior—an ambitious enterprise that requires high degree of interdisciplinary, multi-institutional collaboration. This presentation will explore model-sharing structures that have been successful in promoting earthquake system science within the Southern California Earthquake Center (SCEC). These include disciplinary working groups to aggregate data into community models; numerical-simulation working groups to investigate system-specific phenomena (process modeling) and further improve the data models (inverse modeling); and interdisciplinary working groups to synthesize predictive system-level models. SCEC has developed a cyberinfrastructure, called the Community Modeling Environment, that can distribute the community models; manage large suites of numerical simulations; vertically integrate the hardware, software, and wetware needed for system-level modeling; and promote the interactions among working groups needed for model validation and refinement. Various socio-scientific structures contribute to successful model-sharing. Two of the most important are “communities of trust” and collaborations between government and academic scientists on mission-oriented objectives. The latter include improvements of earthquake forecasts and seismic hazard models and the use of earthquake scenarios in promoting public awareness and disaster management.

The effect of high correlated colour temperature office lighting on employee wellbeing and work performance.

2007-01-11

The effects of lighting on the human circadian system are well-established. The recent discovery of 'non-visual' retinal receptors has confirmed an anatomical basis for the non-image forming, biological effects of light and has stimulated interest in the use of light to enhance wellbeing in the corporate setting. A prospective controlled intervention study was conducted within a shift-working call centre to investigate the effect of newly developed fluorescent light sources with a high correlated colour temperature (17000 K) upon the wellbeing, functioning and work performance of employees. Five items of the SF-36 questionnaire and a modification of the Columbia Jet Lag scale, were used to evaluate employees on two different floors of the call centre between February and May 2005. Questionnaire completion occurred at baseline and after a three month intervention period, during which time one floor was exposed to new high correlated colour temperature lighting and the other remained exposed to usual office lighting. Two sided t-tests with Bonferroni correction for type I errors were used to compare the characteristics of the two groups at baseline and to evaluate changes in the intervention and control groups over the period of the study. Individuals in the intervention arm of the study showed a significant improvement in self-reported ability to concentrate at study end as compared to those within the control arm (p < 0.05). The mean individual score on a 5 point Likert scale improved by 36.8% in the intervention group, compared with only 1.7% in the control group. The majority of this improvement occurred within the first 7 weeks of the 14 week study. Substantial within group improvements were observed in the intervention group in the areas of fatigue (26.9%), alertness (28.2%), daytime sleepiness (31%) and work performance (19.4%), as assessed by the modified Columbia Scale, and in the areas of vitality (28.4%) and mental health (13.9%), as assessed by the SF-36 over the study period. High correlated colour temperature fluorescent lights could provide a useful intervention to improve wellbeing and productivity in the corporate setting, although further work is necessary in quantifying the magnitude of likely benefits.

A unit level, Ada software module testing system, called Query Utility Environment for Software Testing of Ada (QUEST/Ada), is described. The project calls for the design and development of a prototype system. QUEST/Ada design began with a definition of the overall system structure and a description of component dependencies. The project team was divided into three groups to resolve the preliminary designs of the parser/scanner: the test data generator, and the test coverage analyzer. The Phase 1 report is a working document from which the system documentation will evolve. It provides history, a guide to report sections, a literature review, the definition of the system structure and high level interfaces, descriptions of the prototype scope, the three major components, and the plan for the remainder of the project. The appendices include specifications, statistics, two papers derived from the current research, a preliminary users' manual, and the proposal and work plan for Phase 2.

Work groups are a vital link between individuals and organizations. Systematic psychological research on the nature and effects of work groups dates back at least to the Hawthorne studies of the 1920s and 1930s. Yet little to none of this work appeared in the Journal of Applied Psychology until the 1950s when groups were treated primarily as foils against which to compare the performance of individuals. From the 1990s to the present, the volume of research and the nature of topics addressing work group/teams expanded significantly. The authors review the evolution of team research over the past century with a particular focus on that which has appeared in this journal. They chronicle the shift from a focus on individuals within teams, or on individual versus team comparisons, to a focus on the team itself and larger systems of teams. They describe the major outcomes studied within this literature, and how they relate to the nature of team tasks and structures. Further, the authors consider the roles of team members' characteristics and composition, and team dynamics in terms of processes and emergent states. They close with a call for future research that models dynamic team relationships in context and as they operate in complex systems. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Vocal signals such as calls play a crucial role for survival and successful reproduction, especially in group-living animals. However, call interactions and call dynamics within groups remain largely unexplored because their relation to relevant contexts or life-history stages could not be studied with individual-level resolution. Using on-bird microphone transmitters, we recorded the vocalisations of individual zebra finches (Taeniopygia guttata) behaving freely in social groups, while females and males previously unknown to each other passed through different stages of the breeding cycle. As birds formed pairs and shifted their reproductive status, their call repertoire composition changed. The recordings revealed that calls occurred non-randomly in fine-tuned vocal interactions and decreased within groups while pair-specific patterns emerged. Call-type combinations of vocal interactions changed within pairs and were associated with successful egg-laying, highlighting a potential fitness relevance of calling dynamics in communication systems.

Adult meerkats modify close call rate in the presence of pups.

2017-06-01

In animals, signaling behavior is often context-dependent, with variation in the probability of emitting certain signals dependent on fitness advantages. Senders may adjust signaling rate depending on receiver identity, presence of audiences, or noise masking the signal, all of which can affect the benefits and costs of signal production. In the cooperative breeding meerkat Suricata suricatta , group members emit soft contact calls, termed as "close calls", while foraging in order to maintain group cohesion. Here, we investigated how the close calling rate during foraging was affected by the presence of pups, that produce continuous, noisy begging calls as they follow older group members. Adults decreased their overall close call rate substantially when pups were foraging with the group in comparison to periods when no pups were present. We suggest this decrease was likely due to a masking effect of the loud begging calls, which makes the close call function of maintaining group cohesion partly redundant as the centrally located begging calls can be used instead to maintain cohesion. There was some support that adults use close calls strategically to attract specific pups based on fitness advantages, that is, as the philopatric sex, females should call more than males and more to female pups than male pups. Dominant females called more than dominant males when a pup was in close proximity, while subordinates showed no sex-based differences. The sex of the nearest pup did not affect the calling rate of adults. The study shows that meerkats modify their close call production depending on benefits gained from calling and provides an example of the flexible use of one calling system in the presence of another, here contact calls versus begging calls, within the same species.

The objective of the present research was to study the dynamics of changes in emotional energy, work self-efficacy and perceived similarity in the crew of the Mars 520 experimental study. The study comprised six volunteers, all men, between 27-38 yr of age (M = 32.16; SD = 4.99). The Mars 520 experimental study simulated all the elements of the proposed Mars mission that could be ground simulated, i.e., traveling to Mars, orbiting it, landing, and returning to Earth. During the simulation, measures of emotional energy, work self-efficacy, and perceived similarity were repeated every month. The data were analyzed using linear mixed effect models. Emotional energy, work self-efficacy, and perceived similarity gradually increased in the course of the simulation. There was no evidence for a so-called third quarter phenomenon (the most strenuous period of group isolation, psychologically, emotionally, and socially) in our data. On the contrary, work self-efficacy, emotional energy, and group cohesion (indexed here by the subject's perceived similarity to others) increased significantly in the course of the simulation, with the latter two variables showing positive growth in the group functioning.

A working group from across Canada comprised of clinician and basic scientists, epidemiologists, ethicists, Health Canada regulatory authorities and representatives of major funding agencies (Canadian Institutes of Health Research and the Crohn’s and Colitis Foundation of Canada) met to review the current experience with fecal microbial therapy and to identify the key areas of study required to move this field forward. The report highlights the promise of fecal microbial therapy and related synthetic stool therapy (together called ‘microbial ecosystems therapeutics’) for the treatment of Clostridium difficile colitis and, possibly, other disorders. It identifies pressing clinical issues that need to be addressed as well as social, ethical and regulatory barriers to the use of these important therapies. PMID:22803022

Mammographic breast density correlates with breast cancer risk and also with the number of false-negative calls. In the USA these facts lead to the "Breast Density and Mammography Reporting Act" of 2011. In the case of mammographically dense breasts, the Working Group on Breast Ultrasound in Germany recommends explaining the advantages of adjunct imaging to women, depending on the individual breast cancer risk. Due to the particular structure of German healthcare, quality-assured breast ultrasound would be the first choice. Possible overdiagnosis, costs, potentially increased emotional stress should be addressed. In high familial breast cancer risk, genetic counselling and an intensified early detection program should be performed. © Georg Thieme Verlag KG Stuttgart · New York.

Validity of a brief workaholism scale.

2010-02-01

The current study contributes to our understanding of workaholism as a negative construct, and to its measurement by examining the psychometric properties of a short 10-item workaholism scale called DUWAS (Dutch Work Addiction Scale). Confirmatory factor analyses were carried out in a heterogeneous sample of 2,714 employees from the Netherlands (n= 2,164) and Spain (n= 550). The results confirmed the expected two-factor structure of workaholism: working excessively and working compulsively. Moreover, multi-group analyses showed that this two-factor structure was invariant across both countries. Lastly, negative correlations among workaholism and psychosocial well-being (i.e., perceived health and happiness) are indicators of the negative nature of workaholism.

Detailed temporal structure of communication networks in groups of songbirds.

Animals in groups often exchange calls, in patterns whose temporal structure may be influenced by contextual factors such as physical location and the social network structure of the group. We introduce a model-based analysis for temporal patterns of animal call timing, originally developed for networks of firing neurons. This has advantages over cross-correlation analysis in that it can correctly handle common-cause confounds and provides a generative model of call patterns with explicit parameters for the influences between individuals. It also has advantages over standard Markovian analysis in that it incorporates detailed temporal interactions which affect timing as well as sequencing of calls. Further, a fitted model can be used to generate novel synthetic call sequences. We apply the method to calls recorded from groups of domesticated zebra finch (Taeniopygia guttata) individuals. We find that the communication network in these groups has stable structure that persists from one day to the next, and that 'kernels' reflecting the temporal range of influence have a characteristic structure for a calling individual's effect on itself, its partner and on others in the group. We further find characteristic patterns of influences by call type as well as by individual. © 2016 The Authors.

The effect of working on-call from home on the sympatho-adrenal medullary system activity is currently unknown. This study had two aims, Aim 1: examine salivary alpha amylase awakening response (AAR) and diurnal salivary alpha amylase (sAA) profile in fire and emergency service workers who operate on-call from home following a night on-call with a call (NIGHT-CALL), a night on-call without a call (NO-CALL) and an off-call night (OFF-CALL), and Aim 2: explore whether there was an anticipatory effect of working on-call from home (ON) compared to when there was an off-call (OFF) on the diurnal sAA profile. Participants wore activity monitors, completed sleep and work diaries and collected seven saliva samples a day for one week. AAR area under the curve with respect to ground (AUC G ), AAR area under the curve with respect to increase (AUC I ), AAR reactivity, diurnal sAA slope, diurnal sAA AUC G and mean 12-h sAA concentrations were calculated. Separate generalised estimating equation models were constructed for each variable of interest for each aim. For Aim 1, there were no differences between NIGHT-CALL or NO-CALL and OFF-CALL for any response variable. For Aim 2, there was no difference between any response variable of interest when ON the following night compared to when OFF the following night ( n  = 14). These findings suggest that there is no effect of working on-call from home on sAA, but should be interpreted with caution, as overnight data were not collected. Future research, using overnight heart rate monitoring, could help confirm these findings. © 2017 The authors.

This study examined employment and sources of income for different genders and ethnic groups residing in a substance abuse recovery homes called Oxford Houses. Men compared to women reported significantly higher mean income from employment as well as total income. African Americans compared to European Americans reported significantly more work in the past 30 days; however, the rate of pay between these two ethnic groups was not significantly different. Longer length of stay in Oxford House was related to higher incomes. Implications of these findings are discussed.

Support groups for suicide survivors (those individuals bereaved following a suicide) are widely used, but little research evidence is available to determine their efficacy. This paper outlines the pressing public health need to conduct research and determine effective ways to identify and meet the needs of suicide survivors, particularly through survivor support groups. After describing the various approaches to survivor support groups, we explain the need for further research, despite the inherent challenges. Finally, we pose several questions for researchers to consider as they work with survivors to develop a research agenda that sheds more light on the experiences of survivors and the help provided by survivor support groups.

With a constant debate on working hours and improved patient outcomes, time studies are crucial to obtain and analyse timelines and work components. This includes time spent on communication. The aim of this study was to assess the magnitude and patterns of telephone call episodes in the work schedule of neurosurgery trainees. Logs of handheld telephone sets assigned to neurosurgery specialty trainees in a British regional neurosurgical centre were obtained from the hospital switchboard for a 6-month period. This formed the primary data. Ringtime was added to the talktime for outgoing calls. Monday to Friday, 8 am-5 pm was considered as regular hours and the rest as other hours. The outcome measures used were number and duration of telephone episodes (individual and collective) and the timing of these episodes. During the study period of 6 months, there were 12071 incoming calls and 10712 outgoing calls (total calls-22783). The maximum number of incoming calls/ day/ trainee was in the range of 39-78 while the range for outgoing calls was 36-102. On an average, the on-call trainee made and received 33 and 36 calls respectively in a 24-hour period (mean call duration was 1.7 minutes) which meant that a telephone call intruded into the schedule almost once every 21 minutes. Typically, the on-call trainee spent 138 minutes on the telephone (69 calls) in 24 hours, while on an off-call day it was significantly less at 25 minutes (18 calls). Of the calls, 67% happened out of regular hours. Time spent on the telephone is a significant work component and would have a bearing on timelines.

Ethical Principles, Process, and the Work of Bioethics Commissions.

PubMed

Sulmasy, Daniel P

2017-05-01

Shortly after the Presidential Commission for the Study of Bioethical Issues was constituted in 2010 and days before the commission members were to join a conference call to discuss possible topics for their deliberation, Craig Venter held a press conference announcing that his lab had created a synthetic chromosome for a species of mycoplasma and had inserted this genetic material into organisms of another species of mycoplasma (the genes of which had been deactivated), transforming the host species into the donor species. While not overtly claiming to have "created life in the test tube," Venter's publicity seemed cleverly designed to provoke the media into reporting his discovery in just that way. The resulting uproar caused President Obama to give his new bioethics commission the assignment of investigating the ethics of the emerging field of synthetic biology. The commission went right to work. It formed working groups to deliberate about parts of the report, feeding ideas and language to the staff members who would do the actual writing, and then present the working group suggestions to the commission as a whole for public deliberation at open meetings. One of those working groups was charged with coming up with ethical principles that would guide the analysis. Having served as a member of that working group, I report here on the process by which these principles emerged and reflect upon the suitability of that process for the work of public bioethics commissions. © 2017 The Hastings Center.

Reading the Mind in the Eyes or reading between the lines? Theory of Mind predicts collective intelligence equally well online and face-to-face.

PubMed

Engel, David; Woolley, Anita Williams; Jing, Lisa X; Chabris, Christopher F; Malone, Thomas W

2014-01-01

Recent research with face-to-face groups found that a measure of general group effectiveness (called "collective intelligence") predicted a group's performance on a wide range of different tasks. The same research also found that collective intelligence was correlated with the individual group members' ability to reason about the mental states of others (an ability called "Theory of Mind" or "ToM"). Since ToM was measured in this work by a test that requires participants to "read" the mental states of others from looking at their eyes (the "Reading the Mind in the Eyes" test), it is uncertain whether the same results would emerge in online groups where these visual cues are not available. Here we find that: (1) a collective intelligence factor characterizes group performance approximately as well for online groups as for face-to-face groups; and (2) surprisingly, the ToM measure is equally predictive of collective intelligence in both face-to-face and online groups, even though the online groups communicate only via text and never see each other at all. This provides strong evidence that ToM abilities are just as important to group performance in online environments with limited nonverbal cues as they are face-to-face. It also suggests that the Reading the Mind in the Eyes test measures a deeper, domain-independent aspect of social reasoning, not merely the ability to recognize facial expressions of mental states.

Flight calls signal group and individual identity but not kinship in a cooperatively breeding bird.

PubMed

Keen, Sara C; Meliza, C Daniel; Rubenstein, Dustin R

2013-11-01

In many complex societies, intricate communication and recognition systems may evolve to help support both direct and indirect benefits of group membership. In cooperatively breeding species where groups typically comprise relatives, both learned and innate vocal signals may serve as reliable cues for kin recognition. Here, we investigated vocal communication in the plural cooperatively breeding superb starling, Lamprotornis superbus , where flight calls-short, stereotyped vocalizations used when approaching conspecifics-may communicate kin relationships, group membership, and/or individual identity. We found that flight calls were most similar within individual repertoires but were also more similar within groups than within the larger population. Although starlings responded differently to playback of calls from their own versus other neighboring and distant social groups, call similarity was uncorrelated with genetic relatedness. Additionally, immigrant females showed similar patterns to birds born in the study population. Together, these results suggest that flight calls are learned signals that reflect social association but may also carry a signal of individuality. Flight calls, therefore, provide a reliable recognition mechanism for groups and may also be used to recognize individuals. In complex societies comprising related and unrelated individuals, signaling individuality and group association, rather than kinship, may be a route to cooperation.

Practice Based Small Group Learning (PBSGL) is an established learning resource for primary care clinicians in Scotland and is used by one-third of general practitioners (GPs). Scottish Government and UK professional bodies have called for GPs and pharmacists to work more closely together to improve care. To gain GPs' and pharmacists' perceptions and experiences of learning together in an inter-professional PBSGL pilot. Qualitative research methods involving established GP PBSGL groups in NHS Scotland recruiting one or two pharmacists to join them. A grounded theory method was used. GPs were interviewed in focus groups by a fellow GP, and pharmacists were interviewed individually by two researchers, neither being a GP or a pharmacist. Interviews were audio-recorded, transcribed and analysed using grounded theory methods. Data saturation was achieved and confirmed. Three themes were identified: GPs' and pharmacists' perceptions and experiences of inter-professional learning; Inter-professional relationships and team-working; Group identity and purpose of existing GP groups. Pharmacists were welcomed into GP groups and both professions valued inter-professional PBSGL learning. Participants learned from each other and both professions gained a wider perspective of the NHS and of each others' roles in the organisation. Inter-professional relationships, communication and team-working were strengthened and professionals regarded each other as peers and friends.

What Challenges Manual Workers' Ability to Cope with Back Pain at Work, and What Influences Their Decision to Call in Sick?

2015-12-01

Although back pain (BP) is a very common cause for sickness absence, most people stay at work during BP episodes. Existing knowledge on the factors influencing the decision to stay at work despite pain is limited. The aim of this study was to explore challenges for coping with BP at work and decisive factors for work attendance among workers with high physical work demands. Three focus groups (n = 20) were conducted using an explorative inductive method. Participants were public-employed manual workers with high physical work demands. All had personal BP experience. Thematic analysis was used for interpretation. Results were matched with the Flags system framework to guide future recommendations. Workers with BP were challenged by poor physical work conditions and a lack of supervisor support/trust (i.e. lack of adjustment latitude). Organization of workers into teams created close co-worker relationships, which positively affected BP coping. Workers responded to BP by applying helpful individual adjustments to reduce or prevent pain. Traditional ergonomics was considered inconvenient, but nonetheless ideal. When pain was not decisive, the decision to call in sick was mainly governed by workplace factors (i.e. sick absence policies, job strain, and close co-workers relationships) and to a less degree by personal factors. Factors influencing BP coping at work and the decision to report sick was mainly governed by factors concerning general working conditions. Creating a flexible and inclusive working environment guided by the senior management and overall work environment regulations seems favourable.

Spatial release from masking improves sound pattern discrimination along a biologically relevant pulse-rate continuum in gray treefrogs

PubMed Central

Ward, Jessica L.; Buerkle, Nathan P.; Bee, Mark A.

2013-01-01

Frogs form large choruses during the mating season in which males produce loud advertisement calls to attract females and repel rival males. High background noise levels in these social aggregations can impair vocal perception. In humans, spatial release from masking contributes to our ability to understand speech in noisy social groups. Here, we tested the hypothesis that spatial separation between target signals and ‘chorus-shaped noise’ improves the ability of female gray treefrogs (Hyla chrysoscelis) to perform a behavioral discrimination task based on perceiving differences in the pulsatile structure of advertisement calls. We used two-stimulus choice tests to measure phonotaxis (approach toward sound) in response to calls differing in pulse rate along a biologically relevant continuum between conspecific (50 pulses s−1) and heterospecific (20 pulses s−1) calls. Signals were presented in quiet, in colocated noise, and in spatially separated noise. In quiet conditions, females exhibited robust preferences for calls with relatively faster pulse rates more typical of conspecific calls. Behavioral discrimination between calls differing in pulse rate was impaired in the presence of colocated noise but similar between quiet and spatially separated noise conditions. Our results indicate that spatial release from energetic masking facilitates a biologically important temporal discrimination task in frogs. We discuss these results in light of previous work on spatial release from masking in frogs and other animals. PMID:24055623

Ten new species of Oreophryne (Anura, Microhylidae) from Papua New Guinea.

Kraus, Fred

2016-11-17

Oreophryne presently represents the second-most-diverse genus of microhylid frogs, with 57 named species, most occurring on New Guinea and its satellite islands. Nonetheless, a diversity of species remains to be described. Using morphological, color-pattern, and advertisement-call data, I describe ten new species of Oreophryne from the Papuan Peninsula of New Guinea and adjacent islands, which together form the East Papuan Composite Terrane. All but two of these species can be placed into two species groups based on call type. I refer to these species groups as the O. anser group and the O. equus group, both being based on species described herein. Members of the O. anser group produce calls reminiscent of a goose honk, whereas members of the O. equus group produce calls reminiscent of a horse's whinny. Description of three new species in the O. anser group requires me to first rediagnose O. loriae, which has previously been interpreted as including the frogs named herein as O. anser sp. nov. The honk call type has not previously been reported within Oreophryne, and the whinny call may be novel as well, although it is possibly derived from other New Guinean species having calls consisting of a slower series of peeps. Based on their unique call types, I hypothesize that both species groups are monophyletic. If true, each would appear endemic to the East Papuan Composite Terrane. Only five additional species of Oreophryne are known from this region that do not belong to one or the other of these two species groups; hence, these newly identified species groups represent the majority of diversity in Oreophryne from the Papuan Peninsula and its satellite islands.

Fatigue Risk Management: The Impact of Anesthesiology Residents' Work Schedules on Job Performance and a Review of Potential Countermeasures.

Wong, Lily R; Flynn-Evans, Erin; Ruskin, Keith J

2018-04-01

Long duty periods and overnight call shifts impair physicians' performance on measures of vigilance, psychomotor functioning, alertness, and mood. Anesthesiology residents typically work between 64 and 70 hours per week and are often required to work 24 hours or overnight shifts, sometimes taking call every third night. Mitigating the effects of sleep loss, circadian misalignment, and sleep inertia requires an understanding of the relationship among work schedules, fatigue, and job performance. This article reviews the current Accreditation Council for Graduate Medical Education guidelines for resident duty hours, examines how anesthesiologists' work schedules can affect job performance, and discusses the ramifications of overnight and prolonged duty hours on patient safety and resident well-being. We then propose countermeasures that have been implemented to mitigate the effects of fatigue and describe how training programs or practice groups who must work overnight can adapt these strategies for use in a hospital setting. Countermeasures include the use of scheduling interventions, strategic naps, microbreaks, caffeine use during overnight and extended shifts, and the use of bright lights in the clinical setting when possible or personal blue light devices when the room lights must be turned off. Although this review focuses primarily on anesthesiology residents in training, many of the mitigation strategies described here can be used effectively by physicians in practice.

The Cost of Inadequate Sleep among On-Call Workers in Australia: A Workplace Perspective

PubMed Central

Ferguson, Sally A.; Jay, Sarah M.

2018-01-01

On-call or stand-by is becoming an increasingly prevalent form of work scheduling. However, on-call arrangements are typically utilised when workloads are low, for example at night, which can result in inadequate sleep. It is a matter of concern that on-call work is associated with an increased risk of workplace injury. This study sought to determine the economic cost of injury due to inadequate sleep in Australian on-call workers. The prevalence of inadequate sleep among on-call workers was determined using an online survey, and economic costs were estimated using a previously validated costing methodology. Two-thirds of the sample (66%) reported obtaining inadequate sleep on weekdays (work days) and over 80% reported inadequate sleep while on-call. The resulting cost of injury is estimated at $2.25 billion per year ($1.71–2.73 billion). This equates to $1222 per person per incident involving a short-term absence from work; $2.53 million per incident classified as full incapacity, and $1.78 million for each fatality. To the best of our knowledge this is the first study to quantify the economic cost of workplace injury due to inadequate sleep in on-call workers. Well-rested employees are critical to safe and productive workplace operations. Therefore, it is in the interest of both employers and governments to prioritise and invest far more into the management of inadequate sleep in industries which utilise on-call work arrangements.

2018-02-01

The impact of resident work hour restrictions on training and patient care remains a highly controversial topic, and to date, there lacks a formal assessment as it pertains to Canadian plastic surgery residents. To characterize the work hour profile of Canadian plastic surgery residents and assess the perspectives of residents and program directors regarding work hour restrictions related to surgical competency, resident wellness, and patient safety. An anonymous online survey developed by the authors was sent to all Canadian plastic surgery residents and program directors. Basic summary statistics were calculated. Eighty (53%) residents and 10 (77%) program directors responded. Residents reported working an average of 73 hours in hospital per week with 8 call shifts per month and sleep 4.7 hours/night while on call. Most residents (88%) reported averaging 0 post-call days off per month and 61% will work post-call without any sleep. The majority want the option of working post-call (63%) and oppose an 80-hour weekly maximum (77%). Surgical and medical errors attributed to post-call fatigue were self-reported by 26% and 49% of residents, respectively. Residents and program directors expressed concern about the ability to master surgical skills without working post-call. The majority of respondents oppose duty hour restrictions. The reason is likely multifactorial, including the desire of residents to meet perceived expectations and to master their surgical skills while supervised. If duty hour restrictions are aggressively implemented, many respondents feel that an increased duration of training may be necessary.

NASA's MERBoard: An Interactive Collaborative Workspace Platform. Chapter 4

2003-01-01

This chapter describes the ongoing process by which a multidisciplinary group at NASA's Ames Research Center is designing and implementing a large interactive work surface called the MERBoard Collaborative Workspace. A MERBoard system involves several distributed, large, touch-enabled, plasma display systems with custom MERBoard software. A centralized server and database back the system. We are continually tuning MERBoard to support over two hundred scientists and engineers during the surface operations of the Mars Exploration Rover Missions. These scientists and engineers come from various disciplines and are working both in small and large groups over a span of space and time. We describe the multidisciplinary, human-centered process by which this h4ERBoard system is being designed, the usage patterns and social interactions that we have observed, and issues we are currently facing.

Periodic self-rostering in shift work: correspondence between objective work hours, work hour preferences (personal fit), and work schedule satisfaction.

The main objective of the present study was to investigate relative personal fit as the association between rated needs and preferences for work hours, on the one hand, and actual work hours, on the other hand, in three groups (hospital, call-center, and police) working with periodic self-rostering. We also examined the association between personal fit and satisfaction with the work schedule and preference for a fixed and regular shift schedule, respectively. We collected questionnaire data and objective work hour data over 6-12 months from the computerized self-rostering system. The response rate of the questionnaire was 69% at the hospital and call-center and 98% among the police. In total, 29 433 shifts for 285 shift workers were included in the study. Data was analyzed by means of mixed ANOVA, Kendal tau correlations and ordinal (proportional odds) logistic regression. The results show that evening types worked relatively more hours during the evening and night hours compared to morning types as an indication of relative personal fit. Relative personal fit was also found for long shift, short rest, and morning-, evening- and night-shift frequency, but only personal fit related to morning, evening and night-shift was associated with satisfaction with work hours. Reported conflicts at the workplace about work hours and problems with lack of predictability of time for family/leisure activities, was associated with poor satisfaction and a preference for a fixed shift schedule. The present study shows that periodic self-rostering is associated with relative personal fit, in particular with respect to night, evening, and morning work. Personal fit seems to be associated with satisfaction with work hours and may be a moderator of tolerance to shift work exposure.

Two experimental tests of relational models of procedural justice: non-instrumental voice and authority group membership.

In both a laboratory experiment (in Australia) using university as the basis of group membership, and a scenario experiment (in India) using religion as the basis of group membership, we observe more favourable respect and fairness ratings in response to an in-group authority than an out-group authority who administers non-instrumental voice. Moreover, we observe in our second experiment that reported likelihood of protest (herein called "social-change voice") was relatively high following non-instrumental voice from an out-group authority, but relatively low following non-instrumental voice from an in-group authority. Our findings are consistent with relational models of procedural justice, and extend the work by examining likely use of alternative forms of voice as well as highlighting the relative importance of instrumentality. ©2012 The British Psychological Society.

Constructing robust selves after brain injury: positive identity work among members of a female self-help group.

PubMed

Gelech, Jan; Bayly, Melanie; Desjardins, Michel

2017-04-10

Despite common experiences of identity damage, decline, and deterioration, many brain injury survivors succeed in reconstructing robust identities in the wake of injury. Yet, while this accomplishment greatly benefits survivors' quality of life, little is known about how positive identity work might be facilitated or enhanced in therapeutic institutions. Drawing on data from a women's self-help group, we argue that an egalitarian, reflective, strength-focused, and gender-segregated environment can provide female ABI (acquired brain injury) survivors with a fertile scene for identity enhancement and offer unique opportunities for collective identity development. Sociolinguistic interactional analysis revealed four types of positive identity work undertaken within the group: constructing competent selves; tempering the threat of loss and impairment; resisting infantilisation and delegitimisation; and asserting a collective gender identity. This identity work was facilitated by specific programme attributes and activities and contributed to the global project of decentring disability and destigmatising impairments and losses. We call for increased attention to identity issues in brain injury rehabilitation and argue that gender-segregated programming can provide a unique space for female survivors to construct empowering individual and collective identities after injury.

The structure of stereotyped calls reflects kinship and social affiliation in resident killer whales (Orcinus orca).

A few species of mammals produce group-specific vocalisations that are passed on by learning, but the function of learned vocal variation remains poorly understood. Resident killer whales live in stable matrilineal groups with repertoires of seven to 17 stereotyped call types. Some types are shared among matrilines, but their structure typically shows matriline-specific differences. Our objective was to analyse calls of nine killer whale matrilines in British Columbia to test whether call similarity primarily reflects social or genetic relationships. Recordings were made in 1985-1995 in the presence of focal matrilines that were either alone or with groups with non-overlapping repertoires. We used neural network discrimination performance to measure the similarity of call types produced by different matrilines and determined matriline association rates from 757 encounters with one or more focal matrilines. Relatedness was measured by comparing variation at 11 microsatellite loci for the oldest female in each group. Call similarity was positively correlated with association rates for two of the three call types analysed. Similarity of the N4 call type was also correlated with matriarch relatedness. No relationship between relatedness and association frequency was detected. These results show that call structure reflects relatedness and social affiliation, but not because related groups spend more time together. Instead, call structure appears to play a role in kin recognition and shapes the association behaviour of killer whale groups. Our results therefore support the hypothesis that increasing social complexity plays a role in the evolution of learned vocalisations in some mammalian species.

Seeking inclusion in an exclusive process: discourses of medical school student selection.

2015-01-01

Calls to increase medical class representativeness to better reflect the diversity of society represent a growing international trend. There is an inherent tension between these calls and competitive student selection processes driven by academic achievement. How is this tension manifested? Our three-phase interdisciplinary research programme focused on the discourses of excellence, equity and diversity in the medical school selection process, as conveyed by key stakeholders: (i) institutions and regulatory bodies (the websites of 17 medical schools and 15 policy documents from national regulatory bodies); (ii) admissions committee members (ACMs) (according to semi-structured interviews [n = 9]), and (iii) successful applicants (according to semi-structured interviews [n = 14]). The work is theoretically situated within the works of Foucault, Bourdieu and Bakhtin. The conceptual framework is supplemented by critical hermeneutics and the performance theories of Goffman. Academic excellence discourses consistently predominate over discourses calling for greater representativeness in medical classes. Policy addressing demographic representativeness in medicine may unwittingly contribute to the reproduction of historical patterns of exclusion of under-represented groups. In ACM selection practices, another discursive tension is exposed as the inherent privilege in the process is marked, challenging the ideal of medicine as a meritocracy. Applicants' representations of self in the 'performance' of interviewing demonstrate implicit recognition of the power inherent in the act of selection and are manifested in the use of explicit strategies to 'fit in'. How can this critical discourse analysis inform improved inclusiveness in student selection? Policymakers addressing diversity and equity issues in medical school admissions should explicitly recognise the power dynamics at play between the profession and marginalised groups. For greater inclusion and to avoid one authoritative definition of excellence, we suggest a transformative model of faculty development aimed at promoting multiple kinds of excellence. Through this multi-pronged approach, we call for the profession to courageously confront the cherished notion of the medical meritocracy in order to avoid unwanted aspects of elitism. © 2014 John Wiley & Sons Ltd.

[Positive psychology orientation: an intervention proposal for group work in mental health].

Lemos, Patrícia Mendes; Cavalcante Júnior, Francisco Silva

2009-01-01

This investigation aims at presenting a positive approach to psychology applied to the field of mental health in the treatment of patients with mental disorders. The intervention here presented was conducted in therapeutic groups with patients from a psychosocial care center (called CAPS). The analysis of the group work was based on three basic concepts: the humanistic approach and its vision of men and the world, the (con)text method of multiple literacies, and positive psychology. Quantitative and qualitative phenomenological research methodologies were used. The research results were divided into categories based on the group work with patients with depression-related disorders. Seeking for a new model of mental health care aimed at preserving the humanistic approach and the rights of the citizen, the Psychosocial Care Center (CAPS) emerges as a historical result of the construction of the health/disease concept in order to put into practice the principles guiding the psychiatric reform in Brazil. Within this process, a positive approach to psychology is opening horizons for a practice based on a new view of the subject, emphasizing and developing ' virtuous' aspects like the possibility of achieving health in its broader meaning, together health promotion and the employment of different psychological practices.

Using a group-randomized field experimental design, this study tested whether a workplace intervention-designed to reduce work-family conflict-buffered against potential age-related decreases in the affective well-being of employees' children. Daily diary data were collected from 9- to 17-year-old children of parents working in an information technology division of a U.S. Fortune 500 company prior to and 12 months after the implementation of the Support-Transform-Achieve-Results (STAR) workplace intervention. Youth (62 with parents in the STAR group, 41 in the usual-practice group) participated in 8 consecutive nightly phone calls, during which they reported on their daily stressors and affect. Well-being was indexed by positive and negative affect and affective reactivity to daily stressful events. The randomized workplace intervention increased youth positive affect and buffered youth from age-related increases in negative affect and affective reactivity to daily stressors. Future research should test specific conditions of parents' work that may penetrate family life and affect youth well-being. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

The purpose of the PROTOTYPE INTEROPERABILITY DOCUMENT is to document the design and interfaces for the service providers and consumers of a Mission Operations prototype between JSC-OTF and DLR-GSOC. The primary goal is to test the interoperability sections of the CCSDS Spacecraft Monitor & Control (SM&C) Mission Operations (MO) specifications between both control centers. An additional goal is to provide feedback to the Spacecraft Monitor and Control (SM&C) working group through the Review Item Disposition (RID) process. This Prototype is considered a proof of concept and should increase the knowledge base of the CCSDS SM&C Mission Operations standards. No operational capabilities will be provided. The CCSDS Mission Operations (MO) initiative was previously called Spacecraft Monitor and Control (SM&C). The specifications have been renamed to better reflect the scope and overall objectives. The working group retains the name Spacecraft Monitor and Control working group and is under the Mission Operations and Information Services Area (MOIMS) of CCSDS. This document will refer to the specifications as SM&C Mission Operations, Mission Operations or just MO.

Human error and deficient non-technical skills (NTSs) among providers of ALS in helicopter emergency medical services (HEMS) is a threat to patient and operational safety. Skills can be improved through simulation-based training and assessment. To document the current level of simulation-based training and assessment of seven generic NTSs in crew members in the Norwegian HEMS. A cross-sectional survey, either electronic or paper-based, of all 207 physicians, HEMS crew members (HCMs) and pilots working in the civilian Norwegian HEMS (11 bases), between 8 May and 25 July 2012. The response rate was 82% (n=193). A large proportion of each of the professional groups lacked simulation-based training and assessment of their NTSs. Compared with pilots and HCMs, physicians undergo statistically significantly less frequent simulation-based training and assessment of their NTSs. Fifty out of 82 (61%) physicians were on call for more than 72 consecutive hours on a regular basis. Of these, 79% did not have any training in coping with fatigue. In contrast, 72 out of 73 (99%) pilots and HCMs were on call for more than 3 days in a row. Of these, 54% did not have any training in coping with fatigue. Our study indicates a lack of simulation-based training and assessment. Pilots and HCMs train and are assessed more frequently than physicians. All professional groups are on call for extended hours, but receive limited training in how to cope with fatigue. Published by the BMJ Publishing Group Limited.

Using a different mode of contact on the final follow-up to survey non-respondents is an identified strategy to increase response rates. This study was designed to determine if a reminder phone call or a phone interview as a final mode of contact to a mailed survey works better to increase response rates and which strategy is more cost effective. A randomized study was embedded within a survey study of individuals treated with ulcerative colitis conducted in March 2009 in Olmsted County, Minnesota. After two mail contacts, non-respondents were randomly assigned to either a reminder telephone call or a telephone interview. Average cost per completed interview and response rates were compared between the two experimental conditions. The response rate in the reminder group and the interview did not differ where we considered both a completed survey and a signed form a complete (24% vs. 29%, p = 0.08). However, if such a signed form was not required, there was a substantial advantage to completing the interview over the phone (24% vs. 43%, p < 0.0001). The reminder group on average cost $27.00 per completed survey, while the interview group on average cost $53.00 per completed survey when a signed form was required and $36.00 per complete when a signed form was not required. The additional cost of completing an interview is worth it when an additional signed form is not required of the respondent. However, when such a signed form is required, offering an interview instead of a reminder phone call as a follow up to non-respondents does not increase response rates enough to outweigh the additional costs.

The power of women on April 27.

Women make up 54% of voters in South Africa. A delegation of 80 groups representing 2 million women under the Women' National Coalition delivered many research reports on women's issues (e.g., rape, violence, women's status, women workers' rights) to the Transitional Executive Council. If political parties want women to support them, they need to address the inequalities and discrimination women encounter at work, in their homes, and in society. The research findings were a result of 23 focus groups and will be used to draft a Women's Charter. The Coalition will use the Charter to bring about maximum equality within the constitutional framework. The research revealed that sexual harassment at work was more common than was recognized. Black women reported that men of all races in responsible positions seek sex for jobs or for promotion. 50% of women are raped. 1 of 6 women are beaten by their partner. In the past, women's groups were not well supported because White women tended to be satisfied with the status quo. Specifically, they had a servant, leisure time, and a high standard of living. Women are starting to understand that they can be forces of change. A common thread among the diversity of women in the research was a desire for control of their lives. Other issues emerging from the research were women and law, women at work, women and violence, and political awareness among women. The women call for changes in marital law to make sure that women are considered as majors. For example, they should be able to buy property and sign contracts. Women want equal pay for work of equal value, equal treatment when applying for a job. Women want society, including family members, not to ignore domestic violence. They also call on authorities and police to respond more vigorously to domestic violence. Women are becoming more involved in politics, locally, regionally, and nationally.

Residency work hour restrictions in 2003 changed medical student participation in overnight call. The goal is to compare experiences, attitudes, and skills between medical students who did and did not participate in overnight call. Using a retrospective cohort design, all students at one medical school received a survey at the end of their 3rd-year internal medicine clerkship. Students at 3 clerkship sites were required to take overnight call, and students at 2 sites were not. One hundred four of 167 (62%) students participated. Sixty-one of 104 (59%) took overnight call. Overnight call students reported improved team relationships and were able to evaluate more unstable "cross-cover" patients. Students who took overnight call were more likely to state it was worthwhile (58% vs. 34%; p = .034). Overnight call led to fatigue and the perception of interference with didactics. Overnight call within the internal medicine clerkship has positive and negative effects. With new residency work hour restrictions, schools may consider innovative ways to preserve the positive experiences while working to minimize fatigue and interference with learning.

Historically, the clinical neuropsychology training community has not clearly or consistently defined education or training opportunities. The lack of consistency has limited students' and trainees' ability to accurately assess and compare the intensity of neuropsychology-specific training provided by programs. To address these issues and produce greater 'truth in advertising' across programs, CNS, with SCN's Education Advisory Committee (EAC), ADECN, AITCN, and APPCN constructed a specialty-specific taxonomy, namely, the Taxonomy for Education and Training in Clinical Neuropsychology. The taxonomy provides consensus in the description of training offered by doctoral, internship, and postdoctoral programs, as well as at the post-licensure stage. Although the CNS approved the taxonomy in February 2015, many programs have not adopted its language. Increased awareness of the taxonomy and the reasons behind its development and structure, as well as its potential benefits, are warranted. In 2016, a working group of clinical neuropsychologists from the EAC and APPCN, all authors of this manuscript, was created and tasked with disseminating information about the taxonomy. Group members held regular conference calls, leading to the generation of this manuscript. This manuscript is the primary byproduct of the working group. Its purpose is to (1) outline the history behind the development of the taxonomy, (2) detail its structure and utility, (3) address the expected impact of its adoption, and (4) call for its adoption across training programs. This manuscript outlines the development and structure of the clinical neuropsychology taxonomy and addresses the need for its adoption across training programs.

Much ado about mice: Standard-setting in model organism research.

Hardesty, Rebecca A

2018-04-11

Recently there has been a practice turn in the philosophy of science that has called for analyses to be grounded in the actual doings of everyday science. This paper is in furtherance of this call and it does so by employing participant-observation ethnographic methods as a tool for discovering epistemological features of scientific practice in a neuroscience lab. The case I present focuses on a group of neurobiologists researching the genetic underpinnings of cognition in Down syndrome (DS) and how they have developed a new mouse model which they argue should be regarded as the "gold standard" for all DS mouse research. Through use of ethnographic methods, interviews, and analyses of publications, I uncover how the lab constructed their new mouse model. Additionally, I describe how model organisms can serve as abstract standards for scientific work that impact the epistemic value of scientific claims, regulate practice, and constrain future work.

Effective communication is the foundation of feasibility and fidelity in practice-based pragmatic research studies. Doing a study with practices spread over several states requires long-distance communication strategies, including E-mails, faxes, telephone calls, conference calls, and texting. Compared with face-to-face communication, distance communication strategies are less familiar to most study coordinators and research teams. Developing and ensuring comfort with distance communications requires additional time and use of different talents and expertise than those required for face-to-face communication. It is necessary to make sure that messages are appropriate for the medium, clearly crafted, and presented in a manner that facilitates practices receiving and understanding the information. This discussion is based on extensive experience of 2 groups who have worked collaboratively on several large, federally funded, pragmatic trials in a practice-based research network. The goal of this article is to summarize lessons learned to facilitate the work of other research teams.

The Virtual Mission Operations Center

Moore, Mike; Fox, Jeffrey

1994-01-01

Spacecraft management is becoming more human intensive as spacecraft become more complex and as operations costs are growing accordingly. Several automation approaches have been proposed to lower these costs. However, most of these approaches are not flexible enough in the operations processes and levels of automation that they support. This paper presents a concept called the Virtual Mission Operations Center (VMOC) that provides highly flexible support for dynamic spacecraft management processes and automation. In a VMOC, operations personnel can be shared among missions, the operations team can change personnel and their locations, and automation can be added and removed as appropriate. The VMOC employs a form of on-demand supervisory control called management by exception to free operators from having to actively monitor their system. The VMOC extends management by exception, however, so that distributed, dynamic teams can work together. The VMOC uses work-group computing concepts and groupware tools to provide a team infrastructure, and it employs user agents to allow operators to define and control system automation.

Using telemedicine in the care of newborn infants after discharge from a neonatal intensive care unit reduced the need of hospital visits.

This study examined the use of telemedicine as a means to follow up infants discharged from a Swedish neonatal intensive care unit to home health care. Families were randomised to either a control group receiving standard home health care (n = 42 families) or a telemedicine group receiving home health care with telemedicine support (n = 47 families) after discharge from the hospital. Both groups had follow-up hospital appointments with the neonatal nurse. In the telemedicine group, appointments were supplemented by the use of a specially designed web page and video calls. The use of the web page and video calls decreased the number of emergency visits to the hospital (p = 0.047). In the telemedicine group, 26% of the families felt they had more scheduled appointments than necessary, whereas only 6% of the families in the control group thought so (p = 0.037). The parents were highly satisfied with the use of telemedicine. Although the nurses were favourable to using telemedicine, the rigid organisation of the home healthcare programme and the nurses' schedules and work routines prevented its optimal use. The use of telemedicine decreased the need of hospital visits. Organisational adaptations would be necessary to make the best use of telemedicine. ©2016 The Authors.

Mobbing calls signal predator category in a kin group-living bird species

Many prey species gather together to approach and harass their predators despite the associated risks. While mobbing, prey usually utter calls and previous experiments have demonstrated that mobbing calls can convey information about risk to conspecifics. However, the risk posed by predators also differs between predator categories. The ability to communicate predator category would be adaptive because it would allow other mobbers to adjust their risk taking. I tested this idea in Siberian jays Perisoreus infaustus, a group-living bird species, by exposing jay groups to mounts of three hawk and three owl species of varying risks. Groups immediately approached to mob the mount and uttered up to 14 different call types. Jays gave more calls when mobbing a more dangerous predator and when in the presence of kin. Five call types were predator-category-specific and jays uttered two hawk-specific and three owl-specific call types. Thus, this is one of the first studies to demonstrate that mobbing calls can simultaneously encode information about both predator category and the risk posed by a predator. Since antipredator calls of Siberian jays are known to specifically aim at reducing the risk to relatives, kin-based sociality could be an important factor in facilitating the evolution of predator-category-specific mobbing calls.

The goal of this study was to examine the factors that affect career satisfaction in orthopaedic traumatologists. We hypothesize that the level of stress and career satisfaction in orthopaedic traumatology would be affected by increased number of call nights and work hours. A 30-question survey was emailed to members of the OTA. The survey evaluated 5 critical areas: training/experience, practice characteristics, demands, stress management strategies, and satisfaction. After approval by the OTA research committee, all active and associate US members of the OTA were contacted. The survey was open to the OTA members from July through November of 2012. Of 1031 members of the OTA, 263 members responded for an overall response rate of 25.5%. Most respondents were fellowship-trained (218, 82.9%) and predominantly young (<5 years in practice, 34.4%) or established surgeons (>15 years in practice, 28.5%). Most surgeons were married (229, 87.1%) and have not been divorced (226, 85.9%). Career satisfaction was statistically improved by belonging to larger practice (P = 0.016), decreased by work for more hours per week (P = 0.001), and improved by taking more call (P = 0.014). Career satisfaction among orthopaedic trauma surgeons was extremely high. Our results indicate that young surgeons may improve their job satisfaction and potentially prolong their career by limiting the numbers of hours worked, taking a consistent number of calls and joining a larger group.

[Specialised palliative home care (SAPV) in an urban setting--a first year experience].

Vyhnalek, B; Heilmeier, B; Borasio, G D

2011-07-21

The Palliative Home Care Team of the InterdisciplinaryCenterfor Palliative Medicine at Munich University Hospital has been providing Specialized Home Palliative Care (German abbreviation: SAPV) according to the new German regulations since October 2009. Out of 267 requests, 178 patients were accepted for SAPV, 33 thereof at the level of care coordination and 140 as partial or total home palliative care including 24-h, 7/7 on-call duty. Of the latter group, 90 died at home, 19 in a palliative care unit or hospice and one on a hospital ward.The place of death corresponded to the patients' wishes in 98% of cases. Altogether, emergency medical services other than the SAPV team were called upon in 7 cases, and 12 patients were admitted to a general hospital ward. More than a quarter of our patients had non-oncological diagnoses.The proportion of work dealing with family members (21%) was higher than the patient-related one (19%). The highest percentage (37%) represented office work. The requirement for SAPV in the urban setting is high, in spite of the intensive primary care, with an increasing proportion of non-oncological patients. A key aspect concerns the work with family members. SAPV can minimize the number of hospital admissions and emergency calls. The patient's wishes concerning the place of death can be fulfilled. Feed-back from patients and family members indicates that SAPV makes an important contribution towards removing the taboo associated with death and dying.

Nursing work in NHS Direct: constructing a nursing identity in the call-centre environment.

PubMed

Snelgrove, Sherrill Ray

2009-12-01

The introduction of nurse-led telephone helplines for patients to have access to information and advice has led to the development of a new kind of practise for nurses. This study focuses on the ways NHS Direct (NHSD) nurses construct a nursing identity and shape their work in a call-centre environment. The empirical findings are drawn from a study investigating the impact of NHSD on professional nursing issues that was part of a wider evaluation of the service in South Wales, UK. Data were gathered from responses to free text questions included in a questionnaire sent to nurses in three NHSD sites. Further data were collected from focus groups held with NHSD nurses. The nurses defend their identity as nurses rather than call-centre workers. The discourses of the nurses show a strong alignment with the traditional values of nursing, encompassing holistic and empathetic practise that has moved with the nurses across locales. We argue that the nurses frame a nursing identity in NHSD around the importance of previous experience and claim to practise holistic nursing. However, the development of new skills and adaptation of old skills in response to the demand of NHSD work challenges normative notions of traditional 'hands-on' models of practise and indicates a possible movement towards a cognitive model of nursing based upon knowledge, analytical and communication skills that reflects the transformative and dynamic nature of professional identity and boundaries.

Group cohesion in foraging meerkats: follow the moving 'vocal hot spot'.

PubMed

Gall, Gabriella E C; Manser, Marta B

Group coordination, when 'on the move' or when visibility is low, is a challenge faced by many social living animals. While some animals manage to maintain cohesion solely through visual contact, the mechanism of group cohesion through other modes of communication, a necessity when visual contact is reduced, is not yet understood. Meerkats ( Suricata suricatta ), a small, social carnivore, forage as a cohesive group while moving continuously. While foraging, they frequently emit 'close calls', soft close-range contact calls. Variations in their call rates based on their local environment, coupled with individual movement, produce a dynamic acoustic landscape with a moving 'vocal hotspot' of the highest calling activity. We investigated whether meerkats follow such a vocal hotspot by playing back close calls of multiple individuals to foraging meerkats from the front and back edge of the group simultaneously. These two artificially induced vocal hotspots caused the group to spatially elongate and split into two subgroups. We conclude that meerkats use the emergent dynamic call pattern of the group to adjust their movement direction and maintain cohesion. Our study describes a highly flexible mechanism for the maintenance of group cohesion through vocal communication, for mobile species in habitats with low visibility and where movement decisions need to be adjusted continuously to changing environmental conditions.

[Perception of shift work, burnout and sleep disturbances: a study among call centre operators].

Consiglio, Chiara; Tinelli, Erica

2016-01-20

Shift work is often considered to be a factor that can negatively affect health and sleep quality. However, it is usually considered as a structural factor of the job and not as a perception of a work demand. The study aimed at analyzing the relationship between perception of shift work, burnout and sleep disturbances in a potentially stressful context, namely the call centre setting. Call centre operators (N=510) completed a questionnaire encompassing the following scales: perceptions of shift work, monotony, time pressure, exhaustion, cynicism and sleep disturbances. We conducted two hierarchical regressions in order to analyze the contribution of the perception of shift work on burnout dimensions (exhaustion and cynicism), beyond the contribution of socio-demographical variables, and of two specific job stressors for call centre operators, namely monotony and time pressure. The mediating role of exhaustion and cynicism between the perception of shift work and sleep disturbances was also explored. The perception of shift work was associated with operators' burnout, beyond the effect of socio-demographic variables and other job stressors. In addition, the relationship between the perception of shift work and sleep disturbances was fully mediated by exhaustion and partially mediated by cynicism. Perceived shift work may represent a risk factor for the health of call centre operators that should be monitored and possibly managed through specific organizational interventions.

The effects of spatially separated call components on phonotaxis in túngara frogs: evidence for auditory grouping.

PubMed

Farris, Hamilton E; Rand, A Stanley; Ryan, Michael J

2002-01-01

Numerous animals across disparate taxa must identify and locate complex acoustic signals imbedded in multiple overlapping signals and ambient noise. A requirement of this task is the ability to group sounds into auditory streams in which sounds are perceived as emanating from the same source. Although numerous studies over the past 50 years have examined aspects of auditory grouping in humans, surprisingly few assays have demonstrated auditory stream formation or the assignment of multicomponent signals to a single source in non-human animals. In our study, we present evidence for auditory grouping in female túngara frogs. In contrast to humans, in which auditory grouping may be facilitated by the cues produced when sounds arrive from the same location, we show that spatial cues play a limited role in grouping, as females group discrete components of the species' complex call over wide angular separations. Furthermore, we show that once grouped the separate call components are weighted differently in recognizing and locating the call, so called 'what' and 'where' decisions, respectively.

Narrative reflective practice in medical education for residents: composing shifting identities

PubMed Central

Clandinin, Jean; Cave, Marie Thérèse; Cave, Andrew

2011-01-01

As researchers note, medical educators need to create situations to work with physicians in training to help them attend to the development of their professional identities. While there is a call for such changes to be included in medical education, educational approaches that facilitate attention to the development of medical students’ professional identities, that is, who they are and who they are becoming as physicians, are still under development. One pedagogical strategy involves narrative reflective practice as a way to develop physician identity. Using this approach, medical residents first write narrative accounts of their experiences with patients in what are called “parallel charts”. They then engage in a collaborative narrative inquiry within a sustained inquiry group of other residents and two researcher/facilitators (one physician, one narrative researcher). Preliminary studies of this approach are underway. Drawing on the experiences of one medical resident in one such inquiry group, we show how this pedagogical strategy enables attending to physician identity making. PMID:23745070

Psychological stress is a major cause of lost working days in the UK. The Health & Safety Executive (HSE) has developed management standards (MS) to help organizations to assess work-related stress. To investigate the relationships between the MS indicator tool and employee health, job attitudes, work performance and environmental outcomes. The first phase involved a survey employing the MS indicator tool, General Health Questionnaire-12 (GHQ-12), job attitudes, work performance and environmental measures in a call centre from a large utility company. The second phase comprised six focus groups to investigate what employees believed contributed to their perceived stress. Three hundred and four call centre employees responded with a response rate of 85%. Significant negative correlations were found between GHQ-12 and two MS dimensions; demands (Rho = -0.211, P < 0.001) and relationships (Rho= -0.134, P < 0.05). Other dimensions showed no significant relationship with GHQ-12. Higher levels of stress were associated with reduced job performance, job motivation and increased intention to quit but low stress levels were associated with reduced job satisfaction. Lack of management support, recognition and development opportunities were identified as sources of stress. The findings support the utility of the MS as a measure of employee attitudes and performance.

Despite a large body of evidence globally demonstrating that the criminalization of sex workers increases HIV/STI risks, we know far less about the impact of criminalization and policing of managers and in-call establishments on HIV/STI prevention among sex workers, and even less so among migrant sex workers. Analysis draws on ethnographic fieldwork and 46 qualitative interviews with migrant sex workers, managers and business owners of in-call sex work venues in Metro Vancouver, Canada. The criminalization of in-call venues and third parties explicitly limits sex workers' access to HIV/STI prevention, including manager restrictions on condoms and limited onsite access to sexual health information and HIV/STI testing. With limited labour protections and socio-cultural barriers, criminalization and policing undermine the health and human rights of migrant sex workers working in -call venues. This research supports growing evidence-based calls for decriminalization of sex work, including the removal of criminal sanctions targeting third parties and in-call venues, alongside programs and policies that better protect the working conditions of migrant sex workers as critical to HIV/STI prevention and human rights.

Chironomus is one of the important genera in Chironomidae family since they are widely diverse and abundance in aquatic ecosystem. Since Chironomus is very diverse, taxonomic work on this genus is very difficult and incomplete. Objective of this study is to form group classification of Chironomus according to the polytene chromosome mapping. The specific characteristics of polytene chromosomes in the salivary gland appeared to be particularly promising for taxonomic diagnosis of chironomid species. Chironomid larvae were collected from pristine sites at Sg. Langat and cultured in laboratory to reach fourth instar stage. The salivary glands were removed from larvae and chromosomes were stained with aceto orcein. Results showed that polytene chromosomes of Chironomus comprise of three long metacentric or submetacentric arms (BF, CD and AE arms) and one short acrocentric (G arm). In regards to nucleolar organizing region (NOR), Balbiani ring (BR), puffings and chromosome rearrangement, a number of four groups of different banding patterns were found. Two groups called as G group A and B have common NOR on arm BF and BR on arm G. However, group A has rearrangement pattern on arm CD and not in group B. This makes group B separated from group A. Another two groups called as groups C and D do not have common NOR on arm BF and also BR on arm G. Groups C and D were separated using arms G and arm AE. At arm G, only group C rearrangement pattern at unit 23c whereas group D was found to have large NOR at arm G and as well as arm AE, only group D has rearrangement pattern at unit 12c. This study indicates that chromosome arrangement could aid in revealing Chironomus diversity.

Virtual Teams and Human Work Interaction Design - Learning to Work in and Designing for Virtual Teams

Orngreen, Rikke; Clemmensen, Torkil; Pejtersen, Annelise Mark

The boundaries and work processes for how virtual teams interact are undergoing changes, from a tool and stand-alone application orientation, to the use of multiple generic platforms chosen and redesigned to the specific context. These are often at the same time designed both by professional software developers and the individual members of the virtual teams, rather than determined on a single organizational level. There may be no impact of the technology per se on individuals, groups or organizations, as the technology for virtual teams rather enhance situation ambiguity and disrupt existing task-artifact cycles. This ambiguous situation calls for new methods for empirical work analysis and interaction design that can help us understand how organizations, teams and individuals learn to organize, design and work in virtual teams in various networked contexts.

Dilemmas of reform: An exploration of science teachers' collective sensemaking of formative assessment practices

NASA Astrophysics Data System (ADS)

Heredia, Sara Catherine

Current reform efforts in science education call for significant shifts in how science is taught and learned. Teachers are important gatekeepers for reform, as they must enact these changes with students in their own classrooms. As such, professional development approaches need to be developed and studied to understand how teachers interpret and make instructional plans to implement these reforms. However, traditional approaches to studying implementation of reforms often draw on metrics such as time allotted to new activities, rather than exploring the ways in which teachers make sense of these reforms. In this dissertation I draw upon a body of work called sensemaking that has focused on locating learning in teachers' conversations in departmental work groups. I developed a conceptual and analytic framework to analyze how teachers make sense of reform given their local contexts and then used this framework to perform a case study of one group of teachers that participated in larger professional development project that examined the impact of a learning progression on science teachers' formative assessment practices. I draw upon videotapes of three years of monthly professional development meetings as my primary source of data, and used an ethnographic approach to identify dilemmas surfaced by teachers, sources of ambiguity and uncertainty, and patterns of and resources for teacher sensemaking. The case study reveals relationships between the type of dilemma surfaced by the teachers and different patterns of sensemaking for modification of teaching practices. When teachers expressed concerns about district or administrative requirements, they aligned their work in the professional development to those external forces. In contrast, teachers were able to develop and try out new practices when they perceived coherence between the professional development and school or district initiatives. These results underscore the importance of coherence between various components of teachers' work environments.

The dynamics of access to groups in working memory.

PubMed

Farrell, Simon; Lelièvre, Anna

2012-11-01

The finding that participants leave a pause between groups when attempting serial recall of temporally grouped lists has been taken to indicate access to a hierarchical representation of the list in working memory. An alternative explanation is that the dynamics of serial recall solely reflect output (rather than memorial) processes, with the temporal pattern at input merely suggesting a basis for the pattern of output buffering. Three experiments are presented here that disentangle input structure from output buffering in serial recall. In Experiment 1, participants were asked to recall a subset of visually presented digits from a temporally grouped list in their original order, where either within-group position or group position was kept constant. In Experiment 2, participants performed more standard serial recall of spoken digits, and input and output position were dissociated by asking participants to initiate recall from a post-cued position in the list. In Experiment 3, participants were asked to serially recall temporally grouped lists of visually presented digits where the grouping structure was unpredictable, under either articulatory suppression or silent conditions. The 3 experiments point to a tight linkage between implied memorial structures (i.e., the pattern of grouping at encoding) and the output structure implied by retrieval times and call into question a purely motoric account of the dynamics of recall.

The working environment of call centers, which have seen a significant growth in recent years, has been the subject of several studies aiming at understanding its specific dynamics, with particular attention to the possible causes of stress and discomfort. Despite the fact that the work-family conflict is considered a source of stress responsible for undermining workers' well-being, and as such has been explored in many work environments, there is still very little research specific to call centers. This study had the following aims: to explore work-family conflict perceived by call-center operators taking account of any differences related to respondents'professional and personal characteristics; to understand which demands and resources can have an impact on work-family conflict in this context. The study was carried out on a sample of 898 call center operators in a telecommunications company through the administration of a self-reporting questionnaire. Data analysis included: t-test, one-way analysis of variance, linear correlations and multiple regressions. A higher perception of work-family conflict among workers having a full-time contract was observed compared to those having part-time contracts. Multiple regression analysis identified as sources of influence on work-family conflict: emotional dissonance, uneasiness due customer dissatisfaction, workload, avoidance coping and working hours. Work-family conflict in the context studied is not particularly critical: it is in part influenced by professional and personal characteristics of respondents and primarily caused by work demands. Managerial implications are discussed, especially referred to training activities.

Reading the Mind in the Eyes or Reading between the Lines? Theory of Mind Predicts Collective Intelligence Equally Well Online and Face-To-Face

PubMed Central

Engel, David; Woolley, Anita Williams; Jing, Lisa X.; Chabris, Christopher F.; Malone, Thomas W.

2014-01-01

Recent research with face-to-face groups found that a measure of general group effectiveness (called “collective intelligence”) predicted a group’s performance on a wide range of different tasks. The same research also found that collective intelligence was correlated with the individual group members’ ability to reason about the mental states of others (an ability called “Theory of Mind” or “ToM”). Since ToM was measured in this work by a test that requires participants to “read” the mental states of others from looking at their eyes (the “Reading the Mind in the Eyes” test), it is uncertain whether the same results would emerge in online groups where these visual cues are not available. Here we find that: (1) a collective intelligence factor characterizes group performance approximately as well for online groups as for face-to-face groups; and (2) surprisingly, the ToM measure is equally predictive of collective intelligence in both face-to-face and online groups, even though the online groups communicate only via text and never see each other at all. This provides strong evidence that ToM abilities are just as important to group performance in online environments with limited nonverbal cues as they are face-to-face. It also suggests that the Reading the Mind in the Eyes test measures a deeper, domain-independent aspect of social reasoning, not merely the ability to recognize facial expressions of mental states.

Recent initiatives to target the personal, social and clinical needs of people with long-term health conditions have had limited impact within primary care. Evidence of the importance of social networks to support people with long-term conditions points to the need for self-management approaches which align personal circumstances with valued activities. The Patient-Led Assessment for Network Support (PLANS) intervention is a needs-led assessment for patients to prioritise their health and social needs and provide access to local community services and activities. Exploring the work and practices of patients and telephone workers are important for understanding and evaluating the workability and implementation of new interventions. Qualitative methods (interviews, focus group, observations) were used to explore the experience of PLANS from the perspectives of participants and the telephone support workers who delivered it (as part of an RCT) and the reasons why the intervention worked or not. Normalisation Process Theory (NPT) was used as a sensitising tool to evaluate: the relevance of PLANS to patients (coherence); the processes of engagement (cognitive participation); the work done for PLANS to happen (collective action); the perceived benefits and costs of PLANS (reflexive monitoring). 20 patients in the intervention arm of a clinical trial were interviewed and their telephone support calls were recorded and a focus group with 3 telephone support workers was conducted. Analysis of the interviews, support calls and focus group identified three themes in relation to the delivery and experience of PLANS. These are: formulation of 'health' in the context of everyday life; trajectories and tipping points: disrupting everyday routines; precarious trust in networks. The relevance of these themes are considered using NPT constructs in terms of the work that is entailed in engaging with PLANS, taking action, and who is implicated this process. PLANS gives scope to align long-term condition management to everyday life priorities and valued aspects of life. This approach can improve engagement with health-relevant practices by situating them within everyday contexts. This has potential to increase utilisation of local resources with potential cost-saving benefits for the NHS. ISRCTN45433299.

Given the high prevalence of work-associated health problems and the significance of work-related stress factors, cooperation between general practitioners (GPs) and occupational health physicians (OPs) is of particular interest to the healthcare system. Both groups of physicians have an important role to play in supporting prevention, rehabilitation and workplace reintegration. In Germany, however, cooperation between GPs and OPs is often lacking or suboptimal. In our study, we assessed relevant deficiencies in and barriers to this cooperation. Three focus groups were interviewed: GPs, OPs, and medical doctors working in both fields. Data were analysed according to the qualitative content analysis method of P. Mayring. Deficiencies such as lack of communication (e.g., opportunity to make phone calls), insufficient cooperation in regard to sick-leave and professional reintegration, lack of knowledge about the specialty and influence of OPs as well as about patients' working conditions in general. Barriers: Prejudices, competition, mistrust, fear of negative consequences for the patients, lack of legal regulations, or limited accessibility. Similar deficiencies and barriers were mentioned in all three focus groups. The data are helpful in understanding the interface between GPs and OPs in Germany to provide an informative basis for the development of quantitative research instruments for further analysis to improve cooperation. This is the basis for additional cooperation projects. Copyright © 2011. Published by Elsevier GmbH.

Integration of workplace employee health promotion (HP) and occupational health and safety (OHS) work into organizational quality improvement systems is suggested as a way to strengthen HP and OHS activities in an organization. The aim of this article was to study what consequences integration of HP, OHS and a quality improvement system called kaizen has on the frequency and type of HP and OHS activities. A quasi-experimental study design was used where an integration of the three systems for HP, OHS respectively kaizen, was performed at six intervention units at a Swedish hospital. The remaining six units served as controls. Document analysis of all employees' written improvement suggestions (kaizen notes) during 2013 was conducted. The findings show that the intervention group had more suggestions concerning HP and OHS (n = 114) when compared with the control group (n = 78) and a greater variety of HP and OHS suggestions. In addition, only the intervention group had included HP aspects. In both groups, most kaizen notes with health consideration had a preventive focus rather than rehabilitative. The intervention, i.e. the integration of HP, OHS and kaizen work, had a favourable effect on HP and OHS work when compared with the controls. The results of the study support that this system can work in practice at hospitals. © The Author 2015. Published by Oxford University Press. All rights reserved.

Immunity-Based Optimal Estimation Approach for a New Real Time Group Elevator Dynamic Control Application for Energy and Time Saving

PubMed Central

Baygin, Mehmet; Karakose, Mehmet

2013-01-01

Nowadays, the increasing use of group elevator control systems owing to increasing building heights makes the development of high-performance algorithms necessary in terms of time and energy saving. Although there are many studies in the literature about this topic, they are still not effective enough because they are not able to evaluate all features of system. In this paper, a new approach of immune system-based optimal estimate is studied for dynamic control of group elevator systems. The method is mainly based on estimation of optimal way by optimizing all calls with genetic, immune system and DNA computing algorithms, and it is evaluated with a fuzzy system. The system has a dynamic feature in terms of the situation of calls and the option of the most appropriate algorithm, and it also adaptively works in terms of parameters such as the number of floors and cabins. This new approach which provides both time and energy saving was carried out in real time. The experimental results comparatively demonstrate the effects of method. With dynamic and adaptive control approach in this study carried out, a significant progress on group elevator control systems has been achieved in terms of time and energy efficiency according to traditional methods.

The present work is the first of a three-part review on space weather in Latin America. It comprises the evolution of several Latin American institutions investing in space science since the 1960s, focusing on the solar-terrestrial interactions, which today is commonly called space weather. Despite recognizing advances in space research in all of Latin America, this review is restricted to the development observed in three countries in particular (Argentina, Brazil and Mexico), due to the fact that these countries have recently developed operational centers for monitoring space weather. The review starts with a brief summary of the first groups to start working with space science in Latin America. This first part of the review closes with the current status and the research interests of these groups, which are described in relation to the most significant works and challenges of the next decade in order to aid in the solving of space weather open issues.

The aim of this study was to enhance (i) insight in the relationship between different types of employment contract and the quality of working life, health and well-being, and (ii) our causal understanding of these relationships by comparing employees whose contract type changes across time. Analyses were based on a two-year prospective cohort study. Cross-sectional analyses were based upon a sample of 2,454 Dutch employees (2004). Longitudinal data were available for 1,865 respondents (2004-2006). We distinguished among 5 contract types, and subgroups of 'Upward' (i.e., towards permanent employment) and 'Downward' (towards temporary employment) movers across time. Data were analysed with analysis of variance and cross table analysis. Cross-sectionally, we found differences between contract types in quality of working life: generally permanent employees had better jobs, whereas temporary agency workers and on call workers had more 'bad work characteristics'. We also found a difference in health behaviour (smoking) and that psychological health was worst among temporary agency workers. In longitudinal analyses we found some evidence that a positive change in employment contract was associated with a better quality of working life and better psychological health, whereas the opposite was true for a negative contract change. The quality of working life, health and well-being are unequally distributed over employment contract groups. Temporary agency workers and on-call workers deserve special attention in terms of job design and human resource management.

To test three hypotheses in an Italian sample of call center workers: higher levels of perceived work stress are associated with more frequent common mental disorders (GHQ-12) and a lower Work Ability Index; combining the Job Strain (JS) and Effort/Reward Imbalance (ERI) models increases explained variance in health over and above either model when applied separately; compared with outbound operators, inbound call handlers are expected to report a lower health status,which is due to a more intense exposure to task-related work stress factors in the latter. A multi-center cross-sectional study, conducted by means of interviews and self-administered questionnaires. Call handlers working in the Italian branch of a telecommunication multinational company. In all, 1,106 permanent workers were examined (35.9%of the total target population, 98.9% response rate). The majority were women (76.5%);mean age was 33.3 (SD: 3.9) and company seniority 8.0 (SD: 2.1). Nearly 60% worked as inbound call handlers, about one third as outbound operators. Work stress was measured with the well-known JS and ERI models. Three exposure levels (based on tertiles) were identified for each scale. Common mental disorders were measured with the GHQ-12 questionnaire. Subjects with a GHQ-12 score 4 were classified as "cases". The Work Ability Index (WAI) was used to evaluate work ability. Being in the "poor" or "moderate" categories of the WAI indicated a low work ability status. Cronbach's alphas were 0.70 for all scales. Multivariate Poisson regressions showed that both models were linked to more frequent common mental disorders and a lower WAI. Moreover, combined models demonstrated an advantage in terms of explained variance in health. Finally, performing inbound call handling was associated with a lower WAI in comparison with engaging in outbound activities. Mediation analyses showed that such association is explained by the higher levels of psychological job demands and Job Strain experienced by inbound operators. Our results highlight the relevance of work stress as a risk factor for lower psychological health, and especially for a poorer WAI among call center workers. The combined use of the two models increases completeness of work stress assessment in this sector.The higher levels of work stress and the lower WAI observed among inbound operators are due to objectively less favourable task-related characteristics.

The great gerbil, Rhombomys opinus, is a highly social rodent that usually lives in family groups consisting of related females, their offspring, and an adult male. The gerbils emit alarm vocalizations in the presence of diverse predators with different hunting tactics. Alarm calls were recorded in response to three predators, a monitor lizard, hunting dog, and human, to determine whether the most common call type, the rhythmic call, is functionally referential with regard to type of predator. Results show variation in the alarm calls of both adults and subadults with the type of predator. Discriminant function analysis classified an average of 70% of calls to predator type. Call variation, however, was not limited to the predator context, because signal structure also differed by sex, age, individual callers, and family groups. These variations illustrate the flexibility of the rhythmic alarm call of the great gerbil and how it might have multiple functions and communicate in multiple contexts. Three alarm calls, variation in the rhythmic call, and vibrational signals generated from foot-drumming provide the gerbils with a varied and multi-channel acoustic repertoire.

People differ considerably in the way in which they express and experience their nursing careers. The positive effects associated with having a calling may differ substantially based on individuals' abilities to live out their callings. In a working world where many individuals have little to no choice in their type of employment and thus are unable to live out a calling even if they have one, the current study examined how perceiving a calling and living a calling interacted to predict organizational commitment, organizational citizenship behavior, and job stress with career commitment mediating the effect of the interactions on the three outcome variables. The purpose of the study is to investigate the mediating effect of career commitment between the relationships of calling and (a) nurses' attitudes (organizational commitment), (b) behaviors (organizational citizenship behavior), and (c) subjective experiences regarding work (job stress). Using a descriptive exploratory design, data were collected from 332 registered nurses working in Pakistani hospitals. Descriptive analysis and hierarchical regression analysis were used for data analysis. Living a calling moderated the effect of calling on career commitment, organizational citizenship behavior, and job stress, and career commitment fully mediated the effect of calling on organizational commitment, organizational citizenship behavior, and job stress. Increasing the understanding of calling, living a calling, and career commitment may increase nurses' organizational commitment and organizational citizenship behavior and decrease job stress. The study provided evidence to help nursing managers and health policy makers integrate knowledge and skills related to calling into career interventions and help nurses discover their calling.

Deshmukh, A.

An overview is provided for the Fugitive Emissions System (FES) that has been implemented at Occidental Chemical in conjunction with the computer-based maintenance system called PassPort{reg_sign} developed by Indus Corporation. The goal of PassPort{reg_sign} FES program has been to interface with facilities data, equipment information, work standards and work orders. Along the way, several implementation hurdles had to be overcome before a monitoring and regulatory system could be standardized for the appropriate maintenance, process and environmental groups. This presentation includes step-by-step account of several case studies that developed during the implementation of the FES system.

PACS/information systems interoperability using Enterprise Communication Framework.

Interoperability among healthcare applications goes beyond connectivity to allow components to exchange structured information and work together in a predictable, coordinated fashion. To facilitate building an interoperability infrastructure, an Enterprise Communication Framework (ECF) was developed by the members of the Andover Working Group for Healthcare Interoperability (AWG-OHI). The ECF consists of four models: 1) Use Case Model, 2) Domain Information Model (DIM), 3) Interaction Model, and 4) Message Model. To realize this framework, a software component called the Enterprise Communicator (EC) is used. In this paper, we will demonstrate the use of the framework in interoperating a picture archiving and communication system (PACS) with a radiology information system (RIS).

The Name-Letter-Effect in Groups: Sharing Initials with Group Members Increases the Quality of Group Work

Although the name-letter-effect has been demonstrated reliably in choice contexts, recent research has called into question the existence of the name-letter-effect–the tendency among people to make choices that bear remarkable similarity with the letters in their own name. In this paper, we propose a connection between the name-letter-effect and interpersonal, group-level behavior that has not been previously captured in the literature. Specifically, we suggest that sharing initials with other group members promotes positive feelings toward those group members that in turn affect group outcomes. Using both field and laboratory studies, we found that sharing initials with group members cause groups to perform better by demonstrating greater performance, collective efficacy, adaptive conflict, and accuracy (on a hidden-profile task). Although many studies have investigated the effects of member similarity on various outcomes, our research demonstrates how minimal a degree of similarity among members is sufficient to influence quality of group outcomes.

Boundaries of dreams, boundaries of dreamers: thin and thick boundaries as a new personality measure.

PubMed

Hartmann, E

1989-11-01

Previous work by the author and his collaborators on frequent nightmare sufferers demonstrated that these people had striking personality characteristics which could be called "thin boundaries" in a number of different senses. In order to measure thin and thick boundaries, a 145-item questionnaire, the Boundary Questionnaire, has been developed which has now been taken by over 1,000 persons. Preliminary results are presented indicating that, as predicted a priori, several new groups of nightmare sufferers and groups of art students scored usually "thin," whereas a group of naval officers had usually "thick" boundaries. Overall, thinness on the Boundary Questionnaire correlated highly positively (r = .40) with frequency of dream recall and also significantly (r = .16) with length of sleep.

Temporomandibular Disorders (TMD) represent a particular form of chronic pain that, while not outwardly debilitating, profoundly impacts interactions as fundamental to human existence as smiling, laughing, speaking, eating, and intimacy. Our analysis, informed by an expanded “works of illness” assessment, draws attention to work surrounding social and physical risk. We refer to these as the work of stoicism and the work of vigilance and identify double binds created in contexts that call for both. Conflicting authorial stances in informants’ narratives are shown to be essential in maintaining a positive identity in the face of illness. While earlier ethnographic studies report TMD sufferers’ experience of stigma and search for diagnosis and legitimacy, we present a group of individuals who have accepted diagnosis at face value and soldier through pain as a fundamental aspect of their identity.

2014-02-01

The purpose of this study was to understand the impact of a work-based learning program on the work lives of Direct Care Workers (DCWs) at assisted living (AL) residences. The research questions were addressed using focus group data collected as part of a larger evaluation of a work-based learning (WBL) program called Jobs to Careers. The theoretical perspective of symbolic interactionism was used to frame the qualitative data analysis. Results indicated that the WBL program impacted DCWs' job satisfaction through the program curriculum and design and through three primary categories: relational aspects of work, worker identity, and finding time. This article presents a conceptual model for understanding how these categories are interrelated and the implications for WBL programs. Job satisfaction is an important topic that has been linked to quality of care and reduced turnover in long-term care settings.

Nutritional effects on male calling behaviour in the variable field cricket.

PubMed

Wagner; Hoback

1999-01-01

In the variable field cricket, Gryllus lineaticeps, females prefer higher chirp rates and longer chirp durations in male calling song. Higher chirp rates are energetically more expensive to produce, but the energetic cost of calling does not vary with chirp duration. We tested the hypothesis that nutrition affects male chirp rate and chirp duration. Full-sibling brothers of similar age were placed on high- and low-nutrition feeding regimes. There was no effect of feeding regime on male weight; neither group showed a significant change in weight, and the two groups did not differ from each other in weight change. However, males on the high-nutrition feeding regime both called more frequently and called at higher chirp rates when they did call. The two groups did not differ in chirp duration, the duration of pulses within chirps or chirp dominant frequency. These results suggest that females select mates based on one nutrition-dependent call character (chirp rate) and one nutrition-independent call character (chirp duration). In addition, because males in the two groups did not show significant differences in weight change, and because males on the high-nutrition feeding regime engaged in energetically more expensive calling, these results suggest that males invest any excess energy above their basic maintenance requirements in the production of call types that increase their attractiveness to females. The absence of a relationship between body condition and calling song structure for males in the field may be a consequence of this pattern of energy allocation.

In Germany, education in astronomy and planetary sciences is limited to very few schools or universities and is actively pursued by only selected research groups. Our group is situated at the Freie Universität Berlin and we are actively involved in space missions such as Mars Express, Cassini in the Saturnian system, and DAWN at Vesta and Ceres. In order to enhance communication and establish a broader basis for building up knowledge on our solar-system neighborhood, we started to offer educational outreach in the form of workshops for groups of up to 20 students from primary/middle schools to high schools. Small group sizes guarantee practical, interactive, and dialog-based working environments as well as a high level of motivation. Several topical workshops have been designed which are targeted at different age groups and which consider different educational background settings. One workshop called "Impact craters on planets and moons" provides a group-oriented setting in which 3-4 students analyze spacecraft images showing diverse shapes of impact craters on planetary surfaces. It is targeted not only at promoting knowledge about processes on planetary surfaces but it also stimulates visual interpretation skills, 3D viewing and reading of map data. A second workshop "We plan a manned mission to Mars" aims at fostering practical team work by designing simple space mission scenarios which are solved within a team by collaboration and responsibility. A practical outdoor activity called "Everything rotates around the Sun" targets at developing a perception of absolute - but in particular relative - sizes, scales and dimensions of objects in our solar system. Yet another workshop "Craters, volcanoes and co. - become a geologist on Mars" was offered at the annual national "Girls' Day" aiming at motivating primary to middle school girls to deal with topics in classical natural sciences. Small groups investigated and interpreted geomorphologic features in image data of the Martian surface and presented their results in the end. Extensive handouts and high-quality print material supplemented face-to-face exercises. For the future we plan to expand our workshop concepts, to give students the possibility of conducting a week-long internship with our Planetary Sciences research group.

The aim of this study was to describe that which characterises interprofessional trust in a Norwegian emergency department, as expressed by nurses in charge and doctors on call. Interprofessional trust requires knowledge of and skills in interprofessional collaboration. It also requires established trust in fellow collaborators, as well as in the work environment and in the more comprehensive system in which the work is conducted. Nurses in charge and doctors on call who collaborate in the context of an emergency department do so under changing conditions in terms of staff composition and work load. The study was designed in a qualitative, inductive and sequential manner. Data were collected from September-November 2013 through four focus group interviews and was analysed by means of qualitative content analysis. The data revealed two themes that were characteristic of interprofessional trust: 'having relational knowledge' and 'being part of a context'. Together, the themes can be understood as equally important to contextual collaboration. A model of interprofessional trust between an individual level and system level was developed from the results. The study indicates that interprofessional trust is a changeable phenomenon that has great impact on the possibility for development at an individual level and at a more abstract system level. Interprofessional trust can be improved by focusing on trust-building activities between staff at the individual level and between staff and organisation at the system level. Supportive activities such as continuous interprofessional education are suggested as valuable to the development and maintenance of trust. © 2016 John Wiley & Sons Ltd.

EFFECTS OF RESPONDING TO A NAME AND GROUP CALL ON PRESCHOOLERS' COMPLIANCE

We assessed teacher–child relations with respect to children's name calls, instructions, and compliance in a preschool classroom. The most frequent consequence to a child's name being called was the provision of instructions. We also observed a higher probability of compliance when children attended to a name call. Next, we evaluated the effects of teaching preschoolers to attend to their names and a group call on their compliance with typical instructions. We used a multiple baseline design across subjects and a control-group design to evaluate whether gains in compliance were a function of treatment or routine experience in preschool. Results showed that compliance increased as a function of teaching precursors for all children in the experimental group, and the effects on compliance were maintained despite a reduction of the occurrence of precursors. Moreover, it appeared that precursor teaching, not routine preschool experience, was responsible for the changes in compliance. PMID:23322926

Group Random Call Can Positively Affect Student In-Class Clicker Discussions

PubMed Central

Knight, Jennifer K.; Wise, Sarah B.; Sieke, Scott

2016-01-01

Understanding how instructional techniques and classroom norms influence in-class student interactions has the potential to positively impact student learning. Many previous studies have shown that students benefit from discussing their ideas with one another in class. In this study of introductory biology students, we explored how using an in-class accountability system might affect the nature of clicker-question discussions. Clicker-question discussions in which student groups were asked to report their ideas voluntarily (volunteer call) were compared with discussions in which student groups were randomly selected to report their ideas (random call). We hypothesized that the higher-accountability condition (random call) would impress upon students the importance of their discussions and thus positively influence how they interacted. Our results suggest that a higher proportion of discussions in the random call condition contained exchanges of reasoning, some forms of questioning, and both on- and off-topic comments compared with discussion in the volunteer call condition. Although group random call does not impact student performance on clicker questions, the positive impact of this instructional approach on exchanges of reasoning and other features suggests it may encourage some types of student interactions that support learning.

[Bioacoustic of the advertisement call of Ceratophrys cranwelli (Anura: Ceratophryidae)].

PubMed

Valetti, Julián Alonso; Salas, Nancy Edith; Martino, Adolfo Ludovico

2013-03-01

The advertisement call plays an important role in the life history of anuran amphibians, mainly during the breeding season. Call features represent an important character to discriminate species, and sound emissions are very effective to assure or reinforce genetic incompatibility, especially in the case of sibling species. Since frogs are ectotherms, acoustic properties of their calls will vary with temperature. In this study, we described the advertisement call of C. cranwelli, quantifying the temperature effect on its components. The acoustic emissions were recorded during 2007 using a DAT record Sony TCD-100 with stereo microphone ECM-MS907 Sony and tape TDK DAT-RGX 60. As males emit their calls floating in temporary ponds, water temperatures were registered after recording the advertisement calls with a digital thermometer TES 1300+/-0.1 degreeC. Altogether, 54 calls from 18 males were analyzed. The temporal variables of each advertisement call were measured using oscillograms and sonograms and the analyses of dominant frequency were performed using a spectrogram. Multiple correlation analysis was used to identify the temperature-dependent acoustic variables and the temperature effect on these variables was quantified using linear regression models. The advertisement call of C. cranwelli consists of a single pulse group. Call duration, Pulse duration and Pulse interval decreased with the temperature, whereas the Pulse rate increased with temperature. The temperature-dependent variables were standardized at 25 degreeC according to the linear regression model obtained. The acoustic variables that were correlated with the temperature are the variables which emissions depend on laryngeal muscles and the temperature constraints the contractile properties of muscles. Our results indicated that temperature explains an important fraction of the variability in some acoustic variables (79% in the Pulse rate), and demonstrated the importance of considering the effect of temperature in acoustic components. The results suggest that acoustic variables show geographic variation to compare data with previous works.

The report of the so-called Berlin patient cured of HIV with hematopoietic stem cell transplantation and a few other studies raised tremendous hope, excitement, and curiosity in the field. The National Heart, Lung and Blood Institute of the National Institutes of Health convened a Working Group to address emerging heart, lung, and blood research priorities related to HIV infection. Hematopoietic cells could contribute to HIV cure through allogeneic or autologous transplantation of naturally occurring or engineered cells with anti-HIV moieties. Protection of central memory T cells from HIV infection could be a critical determinant of achieving a functional cure. HIV cure can only be achieved if the virus is eradicated from reservoirs in resting T cells and possibly other hematopoietic cells. The Working Group recommended multidisciplinary efforts leveraging HIV and cell therapy expertise to answer the critical need to support research toward an HIV cure.

The gender† dimension of science and technology has become one of the most important and debated issues worldwide, impacting society at every level. A variety of international initiatives on the subject have been undertaken, including the continued monitoring of the status of women in science by Unesco Institute for Statistics (UIS) or the annual reports ``Education at a Glance'' by the Organization for Economic Co-operation and Development (OECD) as well as field-related working groups and networking in order to collect data in a consistent manner. The majority of the international organizations have made clear statements about their discrimination policies (independently of their main field(s) of action), including the International Council for Science whose regulations are followed by the IAU. Gender equality at large is one of the eight United Nations Millennium Development Goals, which clearly calls for action related to science, technology and gender.

Fermi Blobs and the Symplectic Camel: A Geometric Picture of Quantum States

NASA Astrophysics Data System (ADS)

Gossona, Maurice A. De

We have explained in previous work the correspondence between the standard squeezed coherent states of quantum mechanics, and quantum blobs, which are the smallest phase space units compatible with the uncertainty principle of quantum mechanics and having the symplectic group as a group of symmetries. In this work, we discuss the relation between quantum blobs and a certain level set (which we call "Fermi blob") introduced by Enrico Fermi in 1930. Fermi blobs allows us to extend our previous results not only to the excited states of the generalized harmonic oscillator in n dimensions, but also to arbitrary quadratic Hamiltonians. As is the case for quantum blobs, we can evaluate Fermi blobs using a topological notion, related to the uncertainty principle, the symplectic capacity of a phase space set. The definition of this notion is made possible by Gromov's symplectic non-squeezing theorem, nicknamed the "principle of the symplectic camel".

Calling to Nursing: Concept Analysis.

PubMed

Emerson, Christie

The aims of this article are (a) to analyze the concept of a calling as it relates nursing and (b) to develop a definition of calling to nursing with the detail and clarity needed to guide reliable and valid research. The classic steps described by Walker and Avant are used for the analysis. Literature from several disciplines is reviewed including vocational psychology, Christian career counseling, sociology, organizational management, and nursing. The analysis provides an operational definition of a calling to nursing and establishes 3 defining attributes of the concept: (a) a passionate intrinsic motivation or desire (perhaps with a religious component), (b) an aspiration to engage in nursing practice, as a means of fulfilling one's purpose in life, and (c) the desire to help others as one's purpose in life. Antecedents to the concept are personal introspection and cognitive awareness. Positive consequences to the concept are improved work meaningfulness, work engagement, career commitment, personal well-being, and satisfaction. Negative consequences of having a calling might include willingness to sacrifice well-being for work and problems with work-life balance. Following the concept analysis, philosophical assumptions, contextual factors, interdisciplinary work, research opportunities, and practice implications are discussed.

Unlearned calls are produced by all birds whereas learned songs are only found in three avian taxa, most notably in songbirds. The neural basis for song learning and production is formed by interconnected song nuclei: the song control system. In addition to song, zebra finches produce large numbers of soft, unlearned calls, among which "stack" calls are uttered frequently. To determine unequivocally the calls produced by each member of a group, we mounted miniature wireless microphones on each zebra finch. We find that group living paired males and females communicate using bilateral stack calling. To investigate the role of the song control system in call-based male female communication, we recorded the electrical activity in a premotor nucleus of the song control system in freely behaving male birds. The unique combination of acoustic monitoring together with wireless brain recording of individual zebra finches in groups shows that the neuronal activity of the song system correlates with the production of unlearned stack calls. The results suggest that the song system evolved from a brain circuit controlling simple unlearned calls to a system capable of producing acoustically rich, learned vocalizations.

Course-based undergraduate research experiences (CUREs) for non–science majors (nonmajors) are potentially distinct from CUREs for developing scientists in their goals, learning objectives, and assessment strategies. While national calls to improve science, technology, engineering, and mathematics education have led to an increase in research revealing the positive effects of CUREs for science majors, less work has specifically examined whether nonmajors are impacted in the same way. To address this gap in our understanding, a working group focused on nonmajors CUREs was convened to discuss the following questions: 1) What are our laboratory-learning goals for nonmajors? 2) What are our research priorities to determine best practices for nonmajors CUREs? 3) How can we collaborate to define and disseminate best practices for nonmajors in CUREs? We defined three broad student outcomes of prime importance to the nonmajors CURE: improvement of scientific literacy skills, proscience attitudes, and evidence-based decision making. We evaluated the state of knowledge of best practices for nonmajors, and identified research priorities for the future. The report that follows is a summary of the conclusions and future directions from our discussion. PMID:28450449

OBJECTIVE--To determine the advantages and disadvantages of a shift system of working compared with the conventional on call system for preregistration house officers. DESIGN--A shift system of working was employed in the unit from 1 August 1989 to 31 July 1990. During attachments of three or six months four house officers rotated at intervals of one month among three daytime shifts and one night shift (Mondays to Fridays only). Weekends (48 hours) were worked on a one in three rota by the doctors working a day shift. The views of the house officers working this shift system were sought in writing and by direct interview. SETTING--Professorial surgical unit, Royal Liverpool Hospital. SUBJECTS--The 14 house officers who were attached to the unit for three or six months during their preregistration year. RESULTS--The shift system was preferred to conventional on call without exception. The incidence of chronic tiredness was reduced and formal hand-over between shifts resulted in more informed decision making by doctors while on call. During annual leave it was sometimes necessary to revert to the conventional one in three on call system to ensure that daytime work was completed. Other disadvantages were the long weekend shift and an inequitable distribution of the night shift. The house officers recommended extending the shifts to weekends and working the night shift one week in four. CONCLUSION--A shift system of working was effective in reducing chronic tiredness among house officers, who found it preferable to conventional on call arrangements. Shift working is feasible only if the daytime duties of the doctor working at night can be completed by the other doctors on the rota. PMID:1995124

Quantitative descriptions of animal vocalizations can inform an understanding of their evolutionary functions, the mechanisms for their production and perception, and their potential utility in taxonomy, population monitoring, and conservation. The goal of this study was to provide the first acoustical and statistical analysis of the advertisement calls of Nasikabatrachus sahyadrensis. Commonly known as the Indian purple frog, N. sahyadrensis is an endangered species endemic to the Western Ghats of India. As the only known species in its family (Nasikabatrachidae), it has ancient evolutionary ties to frogs restricted to the Seychelles archipelago (Sooglossidae). The role of vocalizations in the behavior of this unique species poses interesting questions, as the animal is fossorial and potentially earless and it breeds explosively above the soil for only about two weeks a year. In this study, we quantified 19 acoustic properties of 208 calls recorded from 10 males. Vocalizations were organized into distinct call groups typically composed of two to six short (59 ms), pulsatile calls, each consisting of about five to seven pulses produced at a rate of about 106 pulses/s. The frequency content of the call consisted of a single dominant peak between 1200–1300 Hz and there was no frequency modulation. The patterns of variation within and among individuals were typical of those seen in other frogs. Few of the properties we measured were related to temperature, body size, or condition, though there was little variation in temperature. Field observations and recordings of captive individuals indicated that males engaged in both antiphonal calling and call overlap with nearby calling neighbors. We discuss our findings in relation to previous work on vocal behavior in other fossorial frogs and in sooglossid frogs. PMID:24516517

Detection of baleen whales on an ocean-bottom seismometer array in the Lau Basin

NASA Astrophysics Data System (ADS)

Brodie, D.; Dunn, R.

2011-12-01

Long-term deployment of ocean-bottom seismometer arrays provides a unique opportunity for identifying and tracking whales in a manner not usually possible in biological studies. Large baleen whales emit low frequency (>5Hz) sounds called 'calls' or 'songs' that can be detected on either the hydrophone or vertical channel of the instrument at distances in excess of 50 km. The calls are distinct to individual species and even geographical groups among species, and are thought to serve a variety of purposes. Distinct repeating calls can be automatically identified using matched-filter processing, and whales can be located in a manner similar to that of earthquakes. Many baleen whale species are endangered, and little is known about their geographic distribution, population dynamics, and basic behaviors. The Lau back-arc basin, a tectonically active, elongated basin bounded by volcanic shallows, lies in the southwestern Pacific Ocean between Fiji and Tonga. Although whales are known to exist around Fiji and Tonga, little is understood about the population dynamics and migration patterns throughout the basin. Twenty-nine broadband ocean-bottom seismometers deployed in the basin recorded data for approximately ten months during the years 2009-2010. To date, four species of whales have been identified in the data: Blue (one call type), Humpback (two call types, including long-lasting 'songs'), Bryde's (one call type), and Fin whales (three call types). Three as-yet-unknown call types have also been identified. After the calls were identified, idealized spectrograms of the known calls were matched against the entire data set using an auto-detection algorithm. The auto-detection output provides the number of calls and times of year when each call type was recorded. Based on the results, whales migrate seasonally through the basin with some overlapping of species. Initial results also indicate that different species of whales are more common in some parts of the basin than others, suggesting preferences in water depth and distance to land. In future work, whales will be tracked through the basin using call localization information to illustrate migration patterns of the various species.

Effect of sleep deprivation on driving safety in housestaff.

Sleep deprivation is known to affect driving safety. Housestaff (HS) are routinely sleep-deprived when on call. We hypothesized that this would affect their driving. We therefore administered questionnaires regarding driving to 70 pediatric HS, who were on call every fourth night, and to 85 faculty members (FAC), who were rarely disturbed at night. HS were questioned about events during their residency, and FAC were questioned about events during the preceding three years. There was an 87% response rate for each group. HS slept 2.7 +/- 0.9 (SD) hours when on call vs 7.2 +/- 0.8 hours when not on call (p < 0.001). 44% of HS had fallen asleep when stopped at a light, vs 12.5% FAC (p < 0.001). 23% of HS had fallen asleep while driving vs. 8% FAC (ns). A total of 49% of HS had fallen asleep at the wheel; 90% of these events occurred post-call. In contrast, only 13% of FAC had fallen asleep at the wheel (p < 0.001). HS had received a total of 25 traffic citations for moving violations vs. 15 for FAC and were involved in 20 motor vehicle accidents vs. 11 for FAC. One traffic citation clearly resulted from HS falling asleep at the wheel vs. none for FAC. We conclude that HS frequently fall asleep when driving post-call. We speculate that current HS work schedules may place some HS at risk for injury to themselves and others. Further study, using prospectively objective measures is indicated.

The work hours of GPs: survey of English GPs.

There is no current information about the hours worked by English GPs. To compare the reported hours worked by GPs with that of other professions and to explain the variation in GP hours worked and on call. National postal survey of 1871 GPs in February 2004. English general practice. Multiple regression analyses of part-time versus full-time status, hours worked, and hours on call. Full-time male GPs report more hours worked (49.6; 95% CI [confidence interval] = 48.9 to 50.2) than males in other professional occupations (47.9; 95% CI = 47.6 to 48.1) and male managers (49.1; 95% CI = 48.8 to 49.5). Full-time female GPs report fewer hours (43.2; 95% CI = 42.0 to 44.3) than females in other professional occupations (44.7; 95% CI = 44.4 to 45.0) and female managers (44.1; 95% CI = 43.7 to 44.5). The number of hours worked decreased with practice list size, and increased with the number of patients per GP. GPs work longer hours in practices with older patients and with a higher proportion of patients in nursing homes. Fewer hours are worked in practices with higher 'additional needs' payments. Having children under 18 years of age increased the probability that female GPs work part-time but has no effect on the probability of male GPs working part-time. Given full-time/part-time status, having children under 18 years of age reduces the hours of male and female GPs. Male English GPs report longer hours worked than other professional groups and managers. The sex differences between GPs in hours worked are mostly attributable to the differential impact of family circumstances, particularly the number of children they have. Perversely, 'additional needs' payments are higher in practices where GPs work fewer hours.

A test of multiple hypotheses for the function of call sharing in female budgerigars, Melopsittacus undulatus

In many social species group, members share acoustically similar calls. Functional hypotheses have been proposed for call sharing, but previous studies have been limited by an inability to distinguish among these hypotheses. We examined the function of vocal sharing in female budgerigars with a two-part experimental design that allowed us to distinguish between two functional hypotheses. The social association hypothesis proposes that shared calls help animals mediate affiliative and aggressive interactions, while the password hypothesis proposes that shared calls allow animals to distinguish group identity and exclude nonmembers. We also tested the labeling hypothesis, a mechanistic explanation which proposes that shared calls are used to address specific individuals within the sender–receiver relationship. We tested the social association hypothesis by creating four–member flocks of unfamiliar female budgerigars (Melopsittacus undulatus) and then monitoring the birds’ calls, social behaviors, and stress levels via fecal glucocorticoid metabolites. We tested the password hypothesis by moving immigrants into established social groups. To test the labeling hypothesis, we conducted additional recording sessions in which individuals were paired with different group members. The social association hypothesis was supported by the development of multiple shared call types in each cage and a correlation between the number of shared call types and the number of aggressive interactions between pairs of birds. We also found support for calls serving as a labeling mechanism using discriminant function analysis with a permutation procedure. Our results did not support the password hypothesis, as there was no difference in stress or directed behaviors between immigrant and control birds. PMID:24860236

Vocal repertoire of free-ranging black howler monkeys' (Alouatta pigra): Call types, contexts, and sex-related contributions.

Alouatta species utter the most powerful primate vocalizations in the Neotropics and are well-known for their loud and long-lasting male howling bouts. However, the diversity of acoustic structures used in these howling bouts, as well as in non-howling contexts, and the relative contribution of the different group members to the entire vocal repertoire, needed to be explored further. This report provides the first detailed description of the vocal repertoire of black howler monkeys (Alouatta pigra), focusing on acoustic structures and contexts of emission of both loud and soft calls as well as on the contribution rate of males and females to the different call types. Three free-ranging social groups of black howler monkeys living in Palenque National Park, Mexico were monitored. We identified twelve acoustically discriminable call types, eight described previously and four described here for the first time. A few call types were systematically emitted either isolated or during howling bouts, but most of them could be heard in both calling contexts. Three call types were emitted only by females and two only by males. Adult males' call rates (for the seven shared call types) were higher than those of females but only when considering calls emitted within howling bouts. Our contextual analysis enabled us to divide call types into potential functional categories, according to their degree of contribution, to intra-group versus inter-group interactions and to neutral-positive versus negative situations. We then discussed how socio-ecological factors, notably sex differences in social behaviors, may explain the variability found in the vocal repertoire of this species and compared our findings with the literature on other primate species. © 2017 Wiley Periodicals, Inc.

Striking a Better Integration of Work and Life: Challenges and Solutions.

Plastic surgeons are a diverse group but share a drive for excellence and dedication to their patients and the advancement of the specialty. Long hours at work and the need to be on call have limited the time that many have to spend on activities outside of the workplace. Reconciliation of the demands of surgery and private life can at times seem impossible. A failure to achieve balance between work and home life is associated with reduced job and life satisfaction, impaired mental health, family conflict, and ultimately burnout. Although the obstacles are many and varied, the authors have attempted to identify the challenges and propose solutions. The authors focus on women in plastic surgery in this article, but acknowledge that these issues are not unique to women or plastic surgery.

Remarks on the "Non-canonicity Puzzle": Lagrangian Symmetries of the Einstein-Hilbert Action

NASA Astrophysics Data System (ADS)

Kiriushcheva, N.; Komorowski, P. G.; Kuzmin, S. V.

2012-07-01

Given the non-canonical relationship between variables used in the Hamiltonian formulations of the Einstein-Hilbert action (due to Pirani, Schild, Skinner (PSS) and Dirac) and the Arnowitt-Deser-Misner (ADM) action, and the consequent difference in the gauge transformations generated by the first-class constraints of these two formulations, the assumption that the Lagrangians from which they were derived are equivalent leads to an apparent contradiction that has been called "the non-canonicity puzzle". In this work we shall investigate the group properties of two symmetries derived for the Einstein-Hilbert action: diffeomorphism, which follows from the PSS and Dirac formulations, and the one that arises from the ADM formulation. We demonstrate that unlike the diffeomorphism transformations, the ADM transformations (as well as others, which can be constructed for the Einstein-Hilbert Lagrangian using Noether's identities) do not form a group. This makes diffeomorphism transformations unique (the term "canonical" symmetry might be suggested). If the two Lagrangians are to be called equivalent, canonical symmetry must be preserved. The interplay between general covariance and the canonicity of the variables used is discussed.

Meerkat close calling patterns are linked to sex, social category, season and wind, but not fecal glucocorticoid metabolite concentrations

It is well established that animal vocalizations can encode information regarding a sender’s identity, sex, age, body size, social rank and group membership. However, the association between physiological parameters, particularly stress hormone levels, and vocal behavior is still not well understood. The cooperatively breeding African meerkats (Suricata suricatta) live in family groups with despotic social hierarchies. During foraging, individuals emit close calls that help maintain group cohesion. These contact calls are acoustically distinctive and variable in rate across individuals, yet, information on which factors influence close calling behavior is missing. The aim of this study was to identify proximate factors that influence variation in call rate and acoustic structure of meerkat close calls. Specifically, we investigated whether close calling behavior is associated with sex, age and rank, or stress hormone output (i.e., measured as fecal glucocorticoid metabolite (fGCM) concentrations) as individual traits of the caller, as well as with environmental conditions (weather) and reproductive seasonality. To disentangle the effects of these factors on vocal behavior, we analyzed sound recordings and assessed fGCM concentrations in 64 wild but habituated meerkats from 9 groups during the reproductive and non-reproductive seasons. Dominant females and one-year old males called at significantly higher rates compared to other social categories during the reproductive season. Additionally, dominant females produced close calls with the lowest mean fundamental frequencies (F0) and the longest mean pulse durations. Windy conditions were associated with significantly higher call rates during the non-reproductive season. Fecal GCM concentrations were unrelated to close calling behavior. Our findings suggest that meerkat close calling behavior conveys information regarding the sex and social category of the caller, but shows no association with fGCM concentrations. The change in call rate in response to variation in the social and ecological environments individuals experience indicates some degree of flexibility in vocal production. PMID:28467419

Considerable resources are spent on habitat restoration across the globe to counter the impacts of habitat loss and degradation on wildlife populations. But, because of time and resourcing constraints on many conservation programs, the effectiveness of these habitat restoration programs in achieving their long-term goals of improving the population viability of particular wildlife species is rarely assessed and many restoration programs cannot demonstrate their effectiveness. Without such demonstration, and in particular demonstrating the causal relationships between habitat restoration actions and demographic responses of the target species, investments in restoration to achieve population outcomes are of uncertain value. Here, we describe an approach that builds on population data collected for a threatened Australian bird - the Grey-crowned Babbler Pomatostomus temporalis - to evaluate how effectively targeted habitat restoration work improves its viability. We built upon an extensive historical survey by conducting surveys 13 years later at 117 sites stratified by presence/absence of restoration works and by detection or not of birds in the first survey. Our performance metric was the number of individuals in a social group, which is both a measure of local abundance and directly related to breeding success. We employed an occupancy model to estimate the response of Grey-crowned Babbler social group size to the effects of time, restoration works, local habitat as measured by the density of large trees, and distance to the nearest other known group of babblers. Babbler group size decreased over the survey period at sites without restoration works, but restoration works were effective in stemming declines where they were done. Restoration was responsible for a difference of about one bird per group of 3-5 individuals; this is an important effect on the reproductive success of the social group. Effectiveness of restoration works targeted at the Grey-crowned Babbler was only demonstrable by sampling through time and including control sites without restoration works. This work demonstrates that while calls for better monitoring of restoration are valid, scope exists to recover a signal of effectiveness from opportunistic retrospective analyses.

Single Electron Tunneling

Ruggiero, Steven T.

Financial support for this project has led to advances in the science of single-electron phenomena. Our group reported the first observation of the so-called ''Coulomb Staircase'', which was produced by tunneling into ultra-small metal particles. This work showed well-defined tunneling voltage steps of width e/C and height e/RC, demonstrating tunneling quantized on the single-electron level. This work was published in a now well-cited Physical Review Letter. Single-electron physics is now a major sub-field of condensed-matter physics, and fundamental work in the area continues to be conducted by tunneling in ultra-small metal particles. In addition, there are now single-electron transistors thatmore » add a controlling gate to modulate the charge on ultra-small photolithographically defined capacitive elements. Single-electron transistors are now at the heart of at least one experimental quantum-computer element, and single-electron transistor pumps may soon be used to define fundamental quantities such as the farad (capacitance) and the ampere (current). Novel computer technology based on single-electron quantum dots is also being developed. In related work, our group played the leading role in the explanation of experimental results observed during the initial phases of tunneling experiments with the high-temperature superconductors. When so-called ''multiple-gap'' tunneling was reported, the phenomenon was correctly identified by our group as single-electron tunneling in small grains in the material. The main focus throughout this project has been to explore single electron phenomena both in traditional tunneling formats of the type metal/insulator/particles/insulator/metal and using scanning tunneling microscopy to probe few-particle systems. This has been done under varying conditions of temperature, applied magnetic field, and with different materials systems. These have included metals, semi-metals, and superconductors. Amongst a number of results, we have verified that clusters of down to one, two, and three metal atoms can be identified with single-electron techniques. We have also, extended the regime of single-electron phenomenology through the observation of single-electron effects in metal droplets in the high-conductance regime.« less

Physicians are often called on to address interpersonal conflicts among office staff and colleagues. Because such strife can interfere with patient care, physicians should learn to diffuse these situations as adeptly and quickly as possible. The authors outline one approach, which they developed while working at the Oklahoma Department of Mental Health. Designated by the mnemonic LIFT (Listen, Inquire, ask for Feedback, Test), this approach has been used successfully to resolve interpersonal conflict in small groups.

Distributed Array Processors (DAP) have been in day to day use for ten years and a large amount of user experience has been gained. The profile of user applications is similar to that of the Massively Parallel Processor (MPP) working group. Experience has shown that contrary to expectations, highly parallel systems provide excellent performance on so-called dirty problems such as the physics part of meteorological codes. The reasons for this observation are discussed. The arguments against replacing bit processors with floating point processors are also discussed.

1998-01-01

The purpose of this study was to determine the personal factors and working conditions that predict work injuries among industrial workers. To fulfill this aim, a case control study was conducted including 2003 industrial workers who sustained a work injury and an equal number of controls. All were subjected to an interview questionnaire to collect relevant information. Moreover, records were reviewed to obtain the medical history of enrolled workers. Data revealed that workers in the index and control groups are comparable in respect to their sociodemographic characteristics. The multivariate logistic regression analysis pointed out that safety training significantly reduces the risk of work accidents among industrial workers. On the other hand, work accidents are more likely to occur in the main working shift. Moreover, workers who suffer from chronic health problems calling for surgical treatment, as well as those who reported family problems, are more likely to experience work accidents. These workers should receive considerable attention to reduce the extent of work injuries. More importantly, safety-training programs are mandatory for accident prevention in industrial settings.

The effects of 2011 Accreditation Council on Graduate Medical Education (ACGME) duty hour standards on intern work hours, patient load, conference attendance, and sleep have not been fully determined. We prospectively compared intern work hours, patient numbers, conference attendance, sleep duration, pattern, and quality in a 2011 ACGME duty hour-compliant shift schedule with a 2003 ACGME duty hour-compliant call schedule at a single pediatric residency program. Interns were assigned to shift or call schedules during 4 alternate months in the winter of 2010-2011. Work hours, patient numbers, conference attendance, sleep duration, pattern, and quality were tracked. Interns worked significantly fewer hours per week on day (73.2 hours) or night (71.6 hours) shifts than during q4 call (79.6 hours; P < .01). During high census months, shift schedule interns cared for significantly more patients/day (8.1/day shift vs 6.2/call; P < .001) and attended significantly fewer conferences than call schedule interns. Night shift interns slept more hours per 24-hour period than call schedule interns (7.2 ± 0.5 vs 6.3 ± 0.9 hours; P < .05) and had more consistent sleep patterns. A shift schedule resulted in reduced intern work hours and improved sleep duration and pattern. Although intern didactic conference attendance declined significantly during high census months, opportunities for experiential learning remained robust with unchanged or increased intern patient numbers.

2007-04-01

To assess the socioeconomic variations in call rates to the Quitline (Victoria, Australia) and in the impact of anti-tobacco television advertising on call rates. The outcome measure was the number of calls to the Quitline in Victoria for each week for each socioeconomic group for the period January 2001 to March 2004. Socioeconomic status (SES) was derived from the caller's postcode using the Index of Socioeconomic Disadvantage provided by the Australian Bureau of Statistics. The exposure measure was weekly Target Audience Rating Points (TARPs, a standard measure of television advertising weight) for anti-tobacco advertising broadcast in Victoria over the same period. Negative binomial regression was used to examine the interaction of SES and TARPs in their effect on the number of Quitline calls. SES and call rates were positively associated. Adjusted call rate was 57% (95% CI 45% to 69%) higher in the highest than the lowest SES quintile. SES differences in call rates were stable over time. In the study period, the effect of the presence or increasing levels of antismoking TARPs on call rates did not vary across categories of SES. In the study period, different SES groups had a similar level of responsiveness to antismoking television advertisements, at least as measured by the rate of calls to the Quitline. However, the present media campaigns are not likely to diminish SES differences in call rates, and more needs to be done to encourage disadvantaged groups to call the Quitline.

Objective To assess the socioeconomic variations in call rates to the Quitline (Victoria, Australia) and in the impact of anti‐tobacco television advertising on call rates. Design The outcome measure was the number of calls to the Quitline in Victoria for each week for each socioeconomic group for the period January 2001 to March 2004. Socioeconomic status (SES) was derived from the caller's postcode using the Index of Socioeconomic Disadvantage provided by the Australian Bureau of Statistics. The exposure measure was weekly Target Audience Rating Points (TARPs, a standard measure of television advertising weight) for anti‐tobacco advertising broadcast in Victoria over the same period. Negative binomial regression was used to examine the interaction of SES and TARPs in their effect on the number of Quitline calls. Results SES and call rates were positively associated. Adjusted call rate was 57% (95% CI 45% to 69%) higher in the highest than the lowest SES quintile. SES differences in call rates were stable over time. In the study period, the effect of the presence or increasing levels of antismoking TARPs on call rates did not vary across categories of SES. Conclusions In the study period, different SES groups had a similar level of responsiveness to antismoking television advertisements, at least as measured by the rate of calls to the Quitline. However, the present media campaigns are not likely to diminish SES differences in call rates, and more needs to be done to encourage disadvantaged groups to call the Quitline. PMID:17372288

Individual killer whale vocal variation during intra-group behavioral dynamics

NASA Astrophysics Data System (ADS)

Grebner, Dawn M.

The scientific goal of this dissertation was to carefully study the signal structure of killer whale communications and vocal complexity and link them to behavioral circumstances. The overall objective of this research sought to provide insight into killer whale call content and usage which may be conveying information to conspecifics in order to maintain group cohesion. Data were collected in the summers of 2006 and 2007 in Johnstone Strait, British Columbia. For both individuals and small groups, vocalizations were isolated using a triangular hydrophone array and the behavioral movement patterns were captured by a theodolite and video camera positioned on a cliff overlooking the hyrophone locations. This dissertation is divided into four analysis chapters. In Chapter 3, discriminant analysis was used to validate the four N04 call subtypes which were originally parsed due to variations in slope segments. The first two functions of the discriminant analysis explained 97% of the variability. Most of the variability for the N04 call was found in the front convex and the terminal portions of the call, while very little variability was found in the center region of the call. This research revealed that individual killer whales produced multiple subtypes of the N04 call. No correlations of behaviors to acoustic parameters obtained were found. The aim of the Chapter 4 was to determine if killer whale calling behavior varied prior to and after the animals had joined. Pulsed call rates were found to be greater pre- compared to post-joining events. Two-way vocal exchanges were more common occurring 74% of the time during pre-joining events. In Chapter 5, initiated and first response to calls varied between age/sex class groups when mothers were separated from an offspring. Solo mothers and calves initiated pulsed calls more often than they responded. Most of the no vocal responses were due to mothers who were foraging. Finally, observations of the frequency split in N04 calls discussed in Chapter 6 showed that the higher frequency component (HFC) was always associated with sideband 7 (SB7) of the lower frequency component (LFC). Insight into Northern Resident killer whale intra-group vocal dynamics would aid our understanding of vocal behaviors of many other marine mammal species that rely on vocal exchanges for prey capture, group movement or survival. This is the first study to focus on killer whale vocal content and usage as it pertains to intra-group dynamics for (1) mother and offspring separations and (2) for all individuals prior to joining events, as well as (3) individual usage in a diverging pulsed call. It is also the first time the N04 call has been parsed into subtypes.

Nurses are at very high risk for work-related musculoskeletal injury/disorders (MSD) with low back pain/injury being the most frequently occurring MSD. Nurses are also likely to work extended schedules (long hours, on-call, mandatory overtime, working on days off). The purpose of this study was to examine the relationship of extended work schedules in nurses to MSD. Using a longitudinal, three wave survey of 2,617 registered nurses, Wave 1 work schedule data were related to neck, shoulder, and back (MSD) cases occurring in Waves 2 or 3. Schedule characteristics increasing MSD risk included 13+ hour/days, off-shifts, weekend work, work during time off (while sick, on days off, without breaks), and overtime/on-call. These increases in risk were not explained by psychological demands, but were largely explained by physical demands. Adverse schedules are significantly related to nurse MSD. Healthier schedules, less overtime, and reducing work on days off would minimize risk and recovery time. Copyright (c) 2006 Wiley-Liss, Inc.

How can universities create engaged citizens and global leaders? Each year, a select group of advanced practice nursing students at Baylor University Louise Herrington School of Nursing travel to Africa for a month-long clinical mission experience. Students work alongside local and missionary healthcare providers in a comprehensive Christian outreach to the community at a high-volume clinic. Creating rich learning experiences in a global setting in significant and sustainable ways is difficult, but intentionally focusing on what we are called to do and who we serve provides ballast for faculty and students. The success of the trip in preparing students to be global influencers is evident by the work graduates elect to do around the world, following graduation.

Introduction to Stand-up Meetings in Agile Methods

In recent years, agile methods have become more popular in the software industry. Agile methods are a new approach compared to plan-driven approaches. One of the most important shifts in adopting an agile approach is the central focus given to people in the process. This is exemplified by the independence afforded to developers in the development work they do. This work investigates the opinions of practitioners about daily stand-up meetings in the agile methods and the role of developer in that. For our investigation we joined a yahoo group called "Extreme Programming". Our investigation suggests that although trust is an important factor in agile methods. But stand-ups are not the place to build trust.

We recorded anuran vocalizations in each of four habitats at Lien Hua Chih Field Station, Taiwan, between July 2000 and July 2001. For each 27 biweekly sample, eight recorders taped calls for 1 min out of every 11 between the hours of 17:00 and 07:00. We obtained 11 481 recordings with calls, and identified 21 503 frogs or groups of frogs. These included 20 species, with an average of 10.4??3.5 species calling each night. Some species called year round, others called in the spring and summer, and a third group called only in the fall and winter. The number of species calling and the maximum calling intensity were correlated with both rainfall and air temperature. The nightly pattern of calling varied among species. Most species called continuously throughout the night, whereas some had a peak right after dusk. A few species had different nightly calling patterns in different habitats. Both Rana limnocharis and Rana kuhlii changed their calling pattern in the presence of large choruses of other anuran species. ?? 2006 The Authors.

Non-specific alarm calls trigger mobbing behavior in Hainan gibbons (Nomascus hainanus).

Alarm calls are important defensive behaviors. Here, we report the acoustic spectrum characteristics of alarm calls produced by Hainan gibbons (Nomascus hainanus) inhabiting Bawangling National Nature Reserve in Hainan, China. Analysis of call data collected from 2002-2014 shows that alarm calls are emitted by all family group members, except infants. Alarm behavior included simple short alarming calls (7-10 min) followed by longer variable-frequency mobbing calls lasting 5-12 min. The duration of individual alarming and mobbing calls was 0.078 ± 0.014 s and 0.154 ± 0.041 s at frequency ranges of 520-1000 Hz and 690-3920 Hz, respectively. Alarming call duration was positively associated with group size. The alarm calls can trigger mobbing behavior in Hainan gibbons; this is a defense way of social animals, and first report among the primates' species. The system of vocal alarm behavior described in this critically endangered species is simple and effective.

Introduction: Relatively few treatment programs have been developed specifically for smokeless tobacco (ST) users who want to quit. Their results suggest that self-help materials, telephone counseling, and nicotine lozenges are efficacious. This study provides the first direct examination of the separate and combined effects of telephone counseling and lozenges. Methods: We recruited ST users online (N = 1067) and randomly assigned them to 1 of 3 conditions: (a) a lozenge group (n = 356), who were mailed 4-mg nicotine lozenges; (b) a coach calls group (n = 354), who were offered 3 coaching phone calls; or (c) a lozenge + coach calls group (N = 357), who received both lozenges and coaching calls. Additionally, all participants were mailed self-help materials. Self-reported tobacco abstinence was assessed at 3 and 6 months after randomization. Results: Complete-case and intention-to-treat (ITT) analyses for all tobacco abstinence were performed at 3 months, 6 months, and both 3 and 6 months (repeated point prevalence). ITT analyses revealed a highly similar result: the lozenge + coach calls condition was significantly more successful in encouraging tobacco abstinence than either the lozenge group or the coach calls group, which did not differ. Conclusions: Combining nicotine lozenges and phone counseling significantly increased tobacco abstinence rates compared with either intervention alone, whereas coach calls and lozenges were equivalent. The study confirms the high tobacco abstinence rates for self-help ST cessation interventions and offers guidance to providing tobacco treatment to ST users. PMID:25168034

The transdisciplinary field of genomics is revolutionizing conceptualizations of health, mental health, family formation, and public policy. Many professions must rapidly acquire genomic expertise to maintain state-of-the-art knowledge in their practice. Calls for social workers to build genomic capacity come regularly, yet social work education has not prepared practitioners to join the genomics workforce in providing socially just, ethically informed care to all clients, particularly those from vulnerable and marginalized groups. The authors suggest a set of action steps for bringing social work skills and practice into the 21st century. They propose that good genomic practice entails bringing social work values, skills, and behaviors to genomics. With education and training, social workers may facilitate socially just dissemination of genomic knowledge and services across practice domains. Increased genomic literacy will support the profession's mission to address disparities in health, health care access, and mortality. © 2016 National Association of Social Workers.

Spacecraft operations including ground system operations are generally realized by various large or small scale group work which is done by operators, engineers, managers, users and so on, and their positions are geographically distributed in many cases. In face-to-face work environments, it is easy for them to understand each other. However, in distributed work environments which need communication media, if only using audio, they become estranged from each other and lose interest in and continuity of work. It is an obstacle to smooth operation of spacecraft. NASDA has developed an experimental model of a new real-time operation control system called 'ADOLIS' (ADvanced On-Line System) adopted to such a distributed environment using a multi-media system dealing with character, figure, image, handwriting, video and audio information which is accommodated to operation systems of a wide range including spacecraft and ground systems. This paper describes the results of the development of the experimental model.

Data categories for marine planning

The U.S. National Ocean Policy calls for a science- and ecosystem-based approach to comprehensive planning and management of human activities and their impacts on America’s oceans. The Ocean Community in Data.gov is an outcome of 2010–2011 work by an interagency working group charged with designing a national information management system to support ocean planning. Within the working group, a smaller team developed a list of the data categories specifically relevant to marine planning. This set of categories is an important consensus statement of the breadth of information types required for ocean planning from a national, multidisciplinary perspective. Although the categories were described in a working document in 2011, they have not yet been fully implemented explicitly in online services or geospatial metadata, in part because authoritative definitions were not created formally. This document describes the purpose of the data categories, provides definitions, and identifies relations among the categories and between the categories and external standards. It is intended to be used by ocean data providers, managers, and users in order to provide a transparent and consistent framework for organizing and describing complex information about marine ecosystems and their connections to humans.

PROBLEM BEING ADDRESSED Medical care in rural Canada has long been hampered by insufficient numbers of physicians. How can a rural community’s physicians change the local medical culture and create a new approach to sustaining their practice? OBJECTIVE OF PROGRAM To create a sustainable, collegial family practice group and address one rural community’s chronically underserviced health care needs. PROGRAM DESCRIPTION Elements important to physicians’ well-being were incorporated into the health care group’s functioning to enhance retention and recruitment. The intentional development of a consensus-based approach to decision making has created a supportive team of physicians. Ongoing communication is kept up through regular meetings, retreats, and a Web-based discussion board. Individual physicians retain control of their hours worked each year and their schedules. A novel obstetric call system was introduced to help make schedules more predictable. An internal governance agreement on an alternative payment plan supports varied work schedules, recognizes and funds non-clinical medical work, and pays group members for undertaking health-related projects. CONCLUSION This approach has helped maintain a stable number of physicians in Marathon, Ont, and has increased the number of health care services delivered to the community. PMID:16190174

Effect of Performance Feedback on Community Health Workers’ Motivation and Performance in Madhya Pradesh, India: A Randomized Controlled Trial

Matheke-Fischer, Michael; Lesh, Neal

2016-01-01

Background Small-scale community health worker (CHW) programs provide basic health services and strengthen health systems in resource-poor settings. This paper focuses on improving CHW performance by providing individual feedback to CHWs working with an mHealth program to address malnutrition in children younger than 5 years. Objective The paper aims to evaluate the immediate and retention effects of providing performance feedback and supportive supervision on CHW motivation and performance for CHWs working with an mHealth platform to reduce malnutrition in five districts of Madhya Pradesh, India. We expected a positive impact on CHW performance for the indicator they received feedback on. Performance on indicators the CHW did not receive feedback on was not expected to change. Methods In a randomized controlled trial, 60 CHWs were randomized into three treatment groups based on overall baseline performance ranks to achieve balanced treatment groups. Data for each treatment indicator were analyzed with the other two treatments acting as the control. In total, 10 CHWs were lost to follow-up. There were three performance indicators: case activity, form submissions, and duration of counseling. Each group received weekly calls to provide performance targets and discuss their performance on the specific indicator they were allocated to as well as any challenges or technical issues faced during the week for a 6-week period. Data were collected for a further 4 weeks to assess intertemporal sustained effects of the intervention. Results We found positive and significant impacts on duration of counseling, whereas case activity and number of form submissions did not show significant improvements as a result of the intervention. We found a moderate to large effect (Glass’s delta=0.97, P=.004) of providing performance feedback on counseling times in the initial 6 weeks. These effects were sustained in the postintervention period (Glass’s delta=1.69, P<.001). The counseling times decreased slightly from the intervention to postintervention period by 2.14 minutes (P=.01). Case activity improved for all CHWs after the intervention. We also performed the analysis by replacing the CHWs lost to follow-up with those in their treatment groups with the closest ranks in baseline performance and found similar results. Conclusions Calls providing performance feedback are effective in improving CHW motivation and performance. Providing feedback had a positive effect on performance in the case of duration of counseling. The results suggest that difficulty in achieving the performance target can affect results of performance feedback. Regardless of the performance information disclosed, calls can improve performance due to elements of supportive supervision included in the calls encouraging CHW motivation. PMID:27927607

Australia is one of the highest users of antibiotics in the developed world. This study aimed to identify consumer antibiotic information needs to improve targeting of medicines information. We conducted a retrospective, mixed-method study of consumers' antibiotic-related calls to Australia's National Prescribing Service (NPS) Medicines Line from September 2002 to June 2010. Demographic and question data were analysed, and the most common enquiry type in each age group was explored for key narrative themes. Relative antibiotic call frequencies were determined by comparing number of calls to antibiotic utilization in Australian Statistics on Medicines (ASM) data. Between 2002 and 2010, consumers made 8696 antibiotic calls to Medicines Line. The most common reason was questions about the role of their medicine (22.4%). Patient age groups differed in enquiry pattern, with more questions about lactation in the 0- to 4-year age group (33.6%), administration (5-14 years: 32.4%), interactions (15-24 years: 33.4% and 25-54 years: 23.3%) and role of the medicine (55 years and over: 26.6%). Key themes were identified for each age group. Relative to use in the community, antibiotics most likely to attract consumer calls were ciprofloxacin (18.0 calls/100,000 ASM prescriptions) and metronidazole (12.9 calls/100,000 ASM prescriptions), with higher call rates than the most commonly prescribed antibiotic amoxicillin (3.9 calls/100,000 ASM prescriptions). Consumers' knowledge gaps and concerns about antibiotics vary with age, and certain antibiotics generate greater concern relative to their usage. Clinicians should target medicines information to proactively address consumer concerns. © The Author 2015. Published by Oxford University Press. All rights reserved.

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 a computer system. 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.).

2005-10-01

Worker's compensation legislation was enacted in Ontario almost 90 years ago. Workers injured on the job gave up their right to sue employers and received no-fault compensation from an independent, employer-funded body called the Workmen's Compensation Board. Three academic health sciences centers in Ontario that are recognized for their commitment to patient care, research, and education compose part of the Specialty Program network with the Ontario Workplace Safety and Insurance Board (WSIB). Statistical data from the WSIB database for workers with hand injuries from 1996 to 2003 show an increase in fractures from fall injuries in the group of women older than 60 that may be related to osteoporosis, a common condition in this group.

Physicians' attentional performance following a 24-hour observation period: do we need to regulate sleep prior to work?

PubMed

Smyth, P; Maximova, K; Jirsch, J D

2017-08-01

The tradition of physicians working while sleep deprived is increasingly criticised. Medical regulatory bodies have restricted resident physician duty-hours, not addressing the greater population of physicians. We aimed to assess factors such as sleep duration prior to a 24-hour observation period on physicians' attention. We studied 70 physicians (mean age 38 years old (SD 10.8 years)): 36 residents and 34 faculty from call rosters at the University of Alberta. Among 70 physicians, 52 (74%) performed overnight call; 18 did not perform overnight call and were recruited to control for the learning effect of repetitive neuropsychological testing. Attentional Network Test (ANT) measured physicians' attention at the beginning and end of the 24-hour observation period. Participants self-reported ideal sleep needs, sleep duration in the 24 hours prior to (ie, baseline) and during the 24-hour observation period (ie, follow-up). Median regression models examined effects on ANT parameters. Sleep deprivation at follow-up was associated with reduced attentional accuracy following the 24-hour observation period, but only for physicians more sleep deprived at baseline. Other components of attention were not associated with sleep deprivation after adjusting for repetitive testing. Age, years since medical school and caffeine use did not impact changes in ANT parameters. Our study suggests that baseline sleep before 24 hours of observation impacts the accuracy of physicians' attentional testing at 24 hours. Further study is required to determine if optimising physician sleep prior to overnight call shifts is a sustainable strategy to mitigate the effects of sleep deprivation.

2012-01-01

Background Bat pups produce individually distinct isolation calls to facilitate maternal recognition. Increasing evidence suggests that, in group-living bat species, adults often use similar calls to maintain contact. We investigated if isolated adults from all three species of the highly cooperative vampire bats (Phyllostomidae: Desmodontinae) would produce vocally distinct contact calls when physically isolated. Methods/Principal Findings We assessed variation in contact calls recorded from isolated captive and wild-caught adult common vampire bats (Desmodus rotundus), white-winged vampire bats (Diaemus youngi) and hairy-legged vampire bats (Diphylla ecaudata). We compared species-typical contact call structure, and used information theory and permuted discriminate function analyses to examine call structure variation, and to determine if the individuality of contact calls is encoded by different call features across species and populations. We found that isolated adult vampire bats produce contact calls that vary by species, population, colony, and individual. However, much variation occurred within a single context and individual. We estimated signature information for captive Diaemus (same colony), captive Desmodus (same colony), and wild Desmodus (different colonies) at 3.21, 3.26, and 3.88 bits, respectively. Contact calls from a captive colony of Desmodus were less individually distinct than calls from wild-caught Desmodus from different colonies. Both the degree of individuality and parameters encoding individuality differed between the bats from a single captive colony and the wild-caught individuals from different groups. This result is consistent with, but not sufficient evidence of, vocal convergence in groups. Conclusion Our results show that adult vampire bats of all three species produce highly variable contact calls when isolated. Contact calls contain sufficient information for vocal discrimination, but also possess more intra-individual variation than is required for the sole purpose of identifying individuals.

2010-01-01

Background Physicians' mental health may be adversely affected by the number of days of work and time spent on-call, and improved by sleep and days-off. The aim of this study was to determine the associations of depressive symptoms with taking days of off duty, hours of sleep, and the number of days of on-call and overnight work among physicians working in Japanese hospitals. Methods A cross-sectional study as a national survey was conducted by mail. The study population was 10,000 randomly selected physicians working in hospitals who were also members of the Japan Medical Association (response rate 40.5%). Self-reported anonymous questionnaire was sent to assess the number of days off-duty, overnight work, and on-calls, and the average number of sleep hours on days not working overnight in the previous one month. Depressive state was determined by the Japanese version of the Quick Inventory of Depressive Symptomatology. Logistic regression analysis was used to explore the associations between depressive symptoms and the studied variables. Results Among the respondents, 8.3% of men and 10.5% of women were determined to be depressed. For both men and women, depressive state was associated with having no off-duty days and averaging less than 5 hours of sleep on days not doing overnight work. Depressive state was positively associated with being on-call more than 5 days per month for men, and more than 8 days per month for women, and was negatively associated with being off-duty more than 8 days per month for men. Conclusion Some physicians need some support to maintain their mental health. Physicians who do not take enough days-off, who reduced sleep hours, and who have certain number of days on-calls may develop depressive symptoms. PMID:20222990

Depressive state was positively associated with being on-call more than 5 days per month for men, and more than 8 days per month for women, and was negatively associated with being off-duty more than 8 days per month for men. Some physicians need some support to maintain their mental health. Physicians who do not take enough days-off, who reduced sleep hours, and who have certain number of days on-calls may develop depressive symptoms.

Medical residents working overnight call shifts experience sleep deprivation and circadian clock disruption. This leads to deficits in sensorimotor function and increases in workplace accidents. Using quick tablet-based tasks, we investigate whether measureable executive function differences exist following a single overnight call versus routine shift, and whether factors like stress, rest and caffeine affect these measures. A prospective, observational, longitudinal, comparison study was conducted. An academic tertiary hospital's main operating room suite staffed by attending anesthesiologists, anesthesiology residents, anesthesiologist assistants and nurse anesthetists. Subjects were 30 anesthesiology residents working daytime shifts and 30 peers working overnight call shifts from the University of Texas Health Science Center at Houston. Before and after their respective work shifts, residents completed the Stanford Sleepiness Scale (SSS) and the ProPoint and AntiPoint tablet-based tasks. These latter tasks are designed to measure sensorimotor and executive functions, respectively. The SSS is a self-reported measure of sleepiness. Response times (RTs) are measured in the pointing tasks. Call residents exhibited increased RTs across their shifts (post-pre) on both ProPoint (p=0.002) and AntiPoint (p<0.002) tasks, when compared to Routine residents. Increased stress was associated with decreases in AntiPoint RT for Routine (p=0.007), but with greater increases in sleepiness for Call residents (p<0.001). Further, whether or not a Call resident consumed caffeine habitually was associated with ProPoint RT changes; with Call residents who habitually drink caffeine having a greater Pre-Post difference (i.e., more slowing, p<0.001) in ProPoint RT. These results indicate that (1) overnight Call residents demonstrate both sensorimotor and cognitive slowing compared to routine daytime shift residents, (2) sensorimotor slowing is greater in overnight Call residents who drink caffeine habitually, and (3) increased stress during a shift reduces (improves) cognitive RTs during routine daytime but not overnight call shifts.

2007-12-01

Vocal communication within and between groups of individuals has been described extensively in birds and terrestrial mammals, however, little is known about how cetaceans utilize their sounds in their natural environment. Resident killer whales, Orcinus orca, live in highly stable matrilines and exhibit group-specific vocal dialects. Single call types cannot exclusively be associated with particular behaviors and calls are thought to function in group identification and intragroup communication. In the present study call usage of three closely related matrilines of the Northern resident community was compared in various intra- and intergroup contexts. In two out of the three matrilines significant changes in vocal behavior depending both on the presence and identity of accompanying whales were found. Most evidently, family-specific call subtypes, as well as aberrant and variable calls, were emitted at higher rates, whereas "low arousal" call types were used less in the presence of matrilines from different pods, subclans, or clans. Ways in which the observed changes may function both in intra- and intergroup communication.

Aligning everyday life priorities with people’s self-management support networks: an exploration of the work and implementation of a needs-led telephone support system

PubMed Central

2014-01-01

Background Recent initiatives to target the personal, social and clinical needs of people with long-term health conditions have had limited impact within primary care. Evidence of the importance of social networks to support people with long-term conditions points to the need for self-management approaches which align personal circumstances with valued activities. The Patient-Led Assessment for Network Support (PLANS) intervention is a needs-led assessment for patients to prioritise their health and social needs and provide access to local community services and activities. Exploring the work and practices of patients and telephone workers are important for understanding and evaluating the workability and implementation of new interventions. Methods Qualitative methods (interviews, focus group, observations) were used to explore the experience of PLANS from the perspectives of participants and the telephone support workers who delivered it (as part of an RCT) and the reasons why the intervention worked or not. Normalisation Process Theory (NPT) was used as a sensitising tool to evaluate: the relevance of PLANS to patients (coherence); the processes of engagement (cognitive participation); the work done for PLANS to happen (collective action); the perceived benefits and costs of PLANS (reflexive monitoring). 20 patients in the intervention arm of a clinical trial were interviewed and their telephone support calls were recorded and a focus group with 3 telephone support workers was conducted. Results Analysis of the interviews, support calls and focus group identified three themes in relation to the delivery and experience of PLANS. These are: formulation of ‘health’ in the context of everyday life; trajectories and tipping points: disrupting everyday routines; precarious trust in networks. The relevance of these themes are considered using NPT constructs in terms of the work that is entailed in engaging with PLANS, taking action, and who is implicated this process. Conclusions PLANS gives scope to align long-term condition management to everyday life priorities and valued aspects of life. This approach can improve engagement with health-relevant practices by situating them within everyday contexts. This has potential to increase utilisation of local resources with potential cost-saving benefits for the NHS. Trial registration ISRCTN45433299. PMID:24938492

Practitioner and communities' awareness of CALFB: Child abuse linked to faith or belief.

This paper reports the results of an online survey which aimed to explore practitioners' and faith community groups' awareness and understanding of child abuse linked to faith or belief (CALFB) and to identify their further training needs in this area. The survey was founded in the work of the National working group for CALFB; a multi-agency response group committed to raising knowledge and awareness of this form of child abuse. Despite the relatively small number of recorded cases, CALFB continues to be a matter of concern to professionals and faith communities in the UK and beyond. One thousand three hundred and sixty two respondents comprising of frontline practitioners, faith and community group members completed the survey. A mixed-method analysis of the survey data illustrates a wide-ranging understanding of the term CALFB and disagreement about whether this is a specific form of child abuse. The results also indicate a relationship between confidence levels in identifying and responding to CALFB and specific training in this area. There is a call for specialised training to be more readily available. Further work is needed to develop a toolkit, which identifies indicators of CALFB and effective response pathways together with research across communities. The current research is timely and important in providing a foundation on which to build more effective identification of cases, policy and intervention. Copyright © 2017 Elsevier Ltd.

Concrete is vulnerable to deterioration, corrosion, and cracks, and the consequent damage and loss of strength requires immensely expensive remediation and repair. So need for special concrete that they would respond to crack formation with an autonomous self-healing action lead to research and development of microbial concrete. The microbial concrete works on the principle of calcite mineral precipitation by a specific group of alkali-resistant spore-forming bacteria related to the genus Bacillus called Bacillus subtilis JC3, this phenomenon is called biomineralization or Microbiologically Induced Calcite Crystal Precipitation. Bacillus subtilis JC3, a common soil bacterium, has inherent ability to precipitate calcite crystals continuously which enhances the strength and durability performance of concrete enormously. This microbial concrete can be called as a "Self healing Bacterial Concrete" because it can remediate its cracks by itself without any human intervention and would make the concrete more durable and sustainable. This paper discuss the incorporation of microorganism Bacillus subtilis JC3 (developed at JNTU, India) into concrete and presents the results of experimental investigations carried out to study the improved durability and sustainability characteristics of microbial concrete.

Background: Workers coming from lowland regions are at risk of developing acute mountain sickness (AMS) when working in low oxygen high-altitude areas. Objectives: The aim of this study was to improve the conditions that lead to hypoxia and ensure the safety of the high-altitude workers. We analyzed the influence of low atmospheric pressure on the oxygen enrichment process in high-altitude areas using an engineering method called low-pressure swing adsorption (LPSA). Methods: Fourteen male subjects were screened and divided into three groups by type of oxygen supply system used: (1) oxygen cylinder group; (2) LPSA oxygen dispersal group; and (3) control group. These tests included arterial oxygen saturation (SaO2), pulse rate (PR), breaths per minute (BPM), and blood pressure (BP). Results: The results showed that after supplying oxygen using the LPSA method at the tunnel face, the SaO2 of workers increased; the incidence of acute mountain sickness, PR, and BPM significantly decreased. Conclusions: The LPSA life support system was found to be a simple, convenient, efficient, reliable, and applicable approach to ensure proper working conditions at construction sites in high-altitude areas.

The number of graduate programs in Optoelectronics in Argentina is scarce. The current Optics and Photonics Education Directory lists only three programs. One of them was launched in 2001 in the Facultad de Ingeniería (College of Engineering), Universidad de Buenos Aires (UBA). This was the first graduate program in the field, leading to a Master Degree in Optoelectronics. This decision arose from the demand of telecommunications industries and several estate- or private-funded research institutions working with us in the fields of lasers, optics, remote sensing, etc. A great bonus was the steady work, during several decades, of research groups in the College on the development of different type of lasers and optical non destructive tests and their engineering applications. As happened in many engineering graduate programs in Argentina at that time, few non full-time students could finish their studies, which called for 800 hours of traditional lecture-recitation classes, and the Master Thesis. In recent years Argentine Education authorities downsized the Master programs to 700 hours of blended learning and we redesigned the Graduate Optoelectronic Engineering Program to meet the challenge, dividing it in two successive one year programs, the first aimed at a professional training for almost immediate insertion in the labor market (called Especialización en Ingeniería Optoelectrónica), and the second (called Maestría en Ingeniería Optoelectrónica y Fotónica) aimed at a more academic and research target to comply with the UBA standards for Master degrees. The present work is a presentation of the new program design, which has begun in the current year.

The World Health Organization calls on health professionals to support women in combining maternity and work. The aim of this study was to explore midwives' and public health nurses' perceptions of supporting employed women to balance work and family life during pregnancy and early motherhood. An exploratory design, including multistage focus group interviews, was used. The focus group consisted of five midwives and one public health nurse who was working in maternity care. The data were analyzed by using qualitative content analysis. The comprehensive theme, "empowering the women when they are in 'another' state of normality", was based on two themes, "being in dialogue with the women" and "supporting the women to manage daily activities". The first theme was based on the subthemes, "perceiving the women to be in 'another' state of normality" and "providing an open atmosphere for dialogue", while the second subtheme was based on "confirming self-esteem" and "suggesting adjustments at work". The midwives and public health nurse empowered the women by enhancing their ability to carry out the self-care that was necessary in order to manage both their work and family life. Collaboration between maternity healthcare providers and employers should be developed in order to support employed women. © 2011 Blackwell Publishing Asia Pty Ltd.

We study the cohesion within and the coalitions between political groups in the Eighth European Parliament (2014–2019) by analyzing two entirely different aspects of the behavior of the Members of the European Parliament (MEPs) in the policy-making processes. On one hand, we analyze their co-voting patterns and, on the other, their retweeting behavior. We make use of two diverse datasets in the analysis. The first one is the roll-call vote dataset, where cohesion is regarded as the tendency to co-vote within a group, and a coalition is formed when the members of several groups exhibit a high degree of co-voting agreement on a subject. The second dataset comes from Twitter; it captures the retweeting (i.e., endorsing) behavior of the MEPs and implies cohesion (retweets within the same group) and coalitions (retweets between groups) from a completely different perspective. We employ two different methodologies to analyze the cohesion and coalitions. The first one is based on Krippendorff’s Alpha reliability, used to measure the agreement between raters in data-analysis scenarios, and the second one is based on Exponential Random Graph Models, often used in social-network analysis. We give general insights into the cohesion of political groups in the European Parliament, explore whether coalitions are formed in the same way for different policy areas, and examine to what degree the retweeting behavior of MEPs corresponds to their co-voting patterns. A novel and interesting aspect of our work is the relationship between the co-voting and retweeting patterns. PMID:27835683

Kaiser Permanente of the Mid-Atlantic States (KPMAS) is collaborating with the Electronic Surveillance System for Early Notification of Community-Based Epidemics II (ESSENCE II) program to understand how managed-care data can be effectively used for syndromic surveillance. This study examined whether KPMAS nurse advice hotline data would be able to predict the syndrome diagnoses made during subsequent KPMAS office visits. All nurse advice hotline calls during 2002 that were linked to an outpatient office visit were identified. By using International Classification of Diseases, Ninth Revision (ICD-9) codes, outpatient visits were categorized into seven ESSENCE II syndrome groups (coma, gastrointestinal, respiratory, neurologic, hemorrhagic, infectious dermatologic, and fever). Nurse advice hotline calls were categorized into ESSENCE II syndrome groups on the basis of the advice guidelines assigned. For each syndrome group, the sensitivity, specificity, and positive predictive value of hotline calls were calculated by using office visits as a diagnostic standard. For matching syndrome call-visit pairs, the lag (i.e., the number of hours that elapsed between the date and time the patient spoke to an advice nurse and the date and time the patient made an office visit) was calculated. Of all syndrome groups, the sensitivity of hotline calls for respiratory syndrome was highest (74.7%), followed by hotline calls for gastrointestinal syndrome (72.0%). The specificity of all nurse advice syndrome groups ranged from 88.9% to 99.9%. The mean lag between hotline calls and office visits ranged from 8.3 to 50 hours, depending on the syndrome group. The timeliness of hotline data capture compared with office visit data capture, as well as the sensitivity and specificity of hotline calls for detecting respiratory and gastrointestinal syndromes, indicate that KPMAS nurse advice hotline data can be used to predict KPMAS syndromic outpatient office visits.

Comparison of French and Worldwide Bacillus anthracis Strains Favors a Recent, Post-Columbian Origin of the Predominant North-American Clade.

Bacillus anthracis, the highly dangerous zoonotic bacterial pathogen species is currently composed of three genetic groups, called A, B and C. Group A is represented worldwide whereas group B is present essentially in Western Europe and Southern Africa. Only three strains from group C have been reported. This knowledge is derived from the genotyping of more than 2000 strains collected worldwide. Strains from both group A and group B are present in France. Previous investigations showed that the majority of sporadic French strains belong to the so-called A.Br.011/009 group A clade and define a very remarkable polytomy with six branches. Here we explore the significance of this polytomy by comparing the French B. anthracis lineages to worldwide lineages. We take advantage of whole genome sequence data previously determined for 122 French strains and 45 strains of various origins. A total of 6690 SNPs was identified among the available dataset and used to draw the phylogeny. The phylogeny of the French B group strains which belongs to B.Br.CNEVA indicates an expansion from the south-east part of France (the Alps) towards the south-west (Massif-Central and Pyrenees). The relatively small group A strains belonging to A.Br.001/002 results from at least two independent introductions. Strikingly, the data clearly demonstrates that the currently predominant B. anthracis lineage in North America, called WNA for Western North American, is derived from one branch of the A.Br.011/009 polytomy predominant in France. The present work extends the range of observed substitution rate heterogeneity within B. anthracis, in agreement with its ecology and in contrast with some other pathogens. The population structure of the six branches A.Br.011/009 polytomy identified in France, diversity of branch length, and comparison with the WNA lineage, suggests that WNA is of post-Columbian and west European origin, with France as a likely source. Furthermore, it is tempting to speculate that the polytomy's most recent common ancestor -MRCA- dates back to the Hundred Years' war between France and England started in the mid-fourteenth century. These events were associated in France with deadly epidemics and major economic and social changes.

Preparing the next generation of nursing scientists to conduct high-impact, competitive, sustainable, innovative, and interdisciplinary programs of research requires that the curricula for PhD programs keep pace with emerging areas of knowledge and health care/biomedical science. A field of inquiry that holds great potential to influence our understanding of the underlying biology and mechanisms of health and disease is omics. For the purpose of this article, omics refers to genomics, transcriptomics, proteomics, epigenomics, exposomics, microbiomics, and metabolomics. Traditionally, most PhD programs in schools of nursing do not incorporate this content into their core curricula. As part of the Council for the Advancement of Nursing Science's Idea Festival for Nursing Science Education, a work group charged with addressing omics preparation for the next generation of nursing scientists was convened. The purpose of this article is to describe key findings and recommendations from the work group that unanimously and enthusiastically support the incorporation of omics content into the curricula of PhD programs in nursing. The work group also calls to action faculty in schools of nursing to develop strategies to enable students needing immersion in omics science and methods to execute their research goals.

This study aimed to evaluate the effect of the Intensive Program of Emotional Intelligence (IPEI; Fernández, 2016; Férreo, 2016) on middle managers’ emotional intelligence, as this variable may have a significant impact on personal satisfaction, task performance, and the work environment. The intervention was applied to work team supervisors in a large call center, as it is an overlooked sector in this topic. Two-hundred and eighty-two supervisors from a Madrid-based, Spanish multinational (51.4% men and 48.6% women) participated in this study. Participants were assigned to the experimental group (n = 190) or the control group (n = 92) by availability, according to management decision. All supervisors filled in two questionnaires to evaluate the different components of intrapersonal emotional intelligence (i.e., attention, clarity, and repair; TMMS-24; Fernández-Berrocal, Extremera, & Ramos, 2004) and cognitive and affective empathy (i.e., perspective taking, emotion understanding, empathic joy, and personal distress; TECA; López-Pérez, Fernández, & Abad, 2008). The findings showed an increase in the studied variables for the experimental group. The results obtained support middle managers’ training in emotional competences through short, efficient, economic programs. Potential limitations and implications of the results are discussed.

The aims of this study were to investigate work conditions, to estimate the prevalence and to describe risk factors associated with Computer Vision Syndrome among two call centers' operators in São Paulo (n = 476). The methods include a quantitative cross-sectional observational study and an ergonomic work analysis, using work observation, interviews and questionnaires. The case definition was the presence of one or more specific ocular symptoms answered as always, often or sometimes. The multiple logistic regression model, were created using the stepwise forward likelihood method and remained the variables with levels below 5% (p < 0.05). The operators were mainly female and young (from 15 to 24 years old). The call center was opened 24 hours and the operators weekly hours were 36 hours with break time from 21 to 35 minutes per day. The symptoms reported were eye fatigue (73.9%), "weight" in the eyes (68.2%), "burning" eyes (54.6%), tearing (43.9%) and weakening of vision (43.5%). The prevalence of Computer Vision Syndrome was 54.6%. Associations verified were: being female (OR 2.6, 95% CI 1.6 to 4.1), lack of recognition at work (OR 1.4, 95% CI 1.1 to 1.8), organization of work in call center (OR 1.4, 95% CI 1.1 to 1.7) and high demand at work (OR 1.1, 95% CI 1.0 to 1.3). The organization and psychosocial factors at work should be included in prevention programs of visual syndrome among call centers' operators.

Divergence of a stereotyped call in northern resident killer whales.

Northern resident killer whale pods (Orcinus orca) have distinctive stereotyped pulsed call repertoires that can be used to distinguish groups acoustically. Repertoires are generally stable, with the same call types comprising the repertoire of a given pod over a period of years to decades. Previous studies have shown that some discrete pulsed calls can be subdivided into variants or subtypes. This study suggests that new stereotyped calls may result from the gradual modification of existing call types through subtypes. Vocalizations of individuals and small groups of killer whales were collected using a bottom-mounted hydrophone array in Johnstone Strait, British Columbia in 2006 and 2007. Discriminant analysis of slope variations of a predominant call type, N4, revealed the presence of four distinct call subtypes. Similar to previous studies, there was a divergence of the N4 call between members of different matrilines of the same pod. However, this study reveals that individual killer whales produced multiple subtypes of the N4 call, indicating that divergence in the N4 call is not the result of individual differences, but rather may indicate the gradual evolution of a new stereotyped call.

Classification of animal vocalizations is often done by a human observer using aural and visual analysis but more efficient, automated methods have also been utilized to reduce bias and increase reproducibility. Beluga whale, Delphinapterus leucas, calls were described from recordings collected in the summers of 2006-2008, in the Churchill River, Manitoba. Calls (n=706) were classified based on aural and visual analysis, and call characteristics were measured; calls were separated into 453 whistles (64.2%; 22 types), 183 pulsed∕noisy calls (25.9%; 15 types), and 70 combined calls (9.9%; seven types). Measured parameters varied within each call type but less variation existed in pulsed and noisy call types and some combined call types than in whistles. A more efficient and repeatable hierarchical clustering method was applied to 200 randomly chosen whistles using six call characteristics as variables; twelve groups were identified. Call characteristics varied less in cluster analysis groups than in whistle types described by visual and aural analysis and results were similar to the whistle contours described. This study provided the first description of beluga calls in Hudson Bay and using two methods provides more robust interpretations and an assessment of appropriate methods for future studies.

Implementation of a Global Navigation Satellite System (GNSS) Augmentation to Tsunami Early Warning Systems

2016-04-01

The Global Geodetic Observing System has issued a Call for Participation to research scientists, geodetic research groups and national agencies in support of the implementation of the IUGG recommendation for a Global Navigation Satellite System (GNSS) Augmentation to Tsunami Early Warning Systems. The call seeks to establish a working group to be a catalyst and motivating force for the definition of requirements, identification of resources, and for the encouragement of international cooperation in the establishment, advancement, and utilization of GNSS for Tsunami Early Warning. During the past fifteen years the populations of the Indo-Pacific region experienced a series of mega-thrust earthquakes followed by devastating tsunamis that claimed nearly 300,000 lives. The future resiliency of the region will depend upon improvements to infrastructure and emergency response that will require very significant investments from the Indo-Pacific economies. The estimation of earthquake moment magnitude, source mechanism and the distribution of crustal deformation are critical to rapid tsunami warning. Geodetic research groups have demonstrated the use of GNSS data to estimate earthquake moment magnitude, source mechanism and the distribution of crustal deformation sufficient for the accurate and timely prediction of tsunamis generated by mega-thrust earthquakes. GNSS data have also been used to measure the formation and propagation of tsunamis via ionospheric disturbances acoustically coupled to the propagating surface waves; thereby providing a new technique to track tsunami propagation across ocean basins, opening the way for improving tsunami propagation models, and providing accurate warning to communities in the far field. These two new advancements can deliver timely and accurate tsunami warnings to coastal communities in the near and far field of mega-thrust earthquakes. This presentation will present the justification for and the details of the GGOS Call for Participation.

Is killer whale dialect evolution random?

PubMed

Filatova, Olga A; Burdin, Alexandr M; Hoyt, Erich

2013-10-01

The killer whale is among the few species in which cultural change accumulates over many generations, leading to cumulative cultural evolution. Killer whales have group-specific vocal repertoires which are thought to be learned rather than being genetically coded. It is supposed that divergence between vocal repertoires of sister groups increases gradually over time due to random learning mistakes and innovations. In this case, the similarity of calls across groups must be correlated with pod relatedness and, consequently, with each other. In this study we tested this prediction by comparing the patterns of call similarity between matrilines of resident killer whales from Eastern Kamchatka. We calculated the similarity of seven components from three call types across 14 matrilines. In contrast to the theoretical predictions, matrilines formed different clusters on the dendrograms made by different calls and even by different components of the same call. We suggest three possible explanations for this phenomenon. First, the lack of agreement between similarity patterns of different components may be the result of constraints in the call structure. Second, it is possible that call components change in time with different speed and/or in different directions. Third, horizontal cultural transmission of call features may occur between matrilines.

Auditors of a large terminology, such as SNOMED CT, face a daunting challenge. To aid them in their efforts, it is essential to devise techniques that can automatically identify concepts warranting special attention.

Auditors of a large terminology, such as SNOMED CT, face a daunting challenge. To aid them in their efforts, it is essential to devise techniques that can automatically identify concepts warranting special attention. “Complex” concepts, which by their very nature are more difficult to model, fall neatly into this category. A special kind of grouping, called a partial-area, is utilized in the characterization of complex concepts. In particular, the complex concepts that are the focus of this work are those appearing in intersections of multiple partial-areas and are thus referred to as overlapping concepts. In a companion paper, an automatic methodology for identifying and partitioning the entire collection of overlapping concepts into disjoint, singly-rooted groups, that are more manageable to work with and comprehend, has been presented. The partitioning methodology formed the foundation for the development of an abstraction network for the overlapping concepts called a disjoint partial-area taxonomy. This new disjoint partial-area taxonomy offers a collection of semantically uniform partial-areas and is exploited herein as the basis for a novel auditing methodology. The review of the overlapping concepts is done in a top-down order within semantically uniform groups. These groups are themselves reviewed in a top-down order, which proceeds from the less complex to the more complex overlapping concepts.

Alarm calls are important defensive behaviors. Here, we report the acoustic spectrum characteristics of alarm calls produced by Hainan gibbons (Nomascus hainanus) inhabiting Bawangling National Nature Reserve in Hainan, China. Analysis of call data collected from 2002–2014 shows that alarm calls are emitted by all family group members, except infants. Alarm behavior included simple short alarming calls (7–10 min) followed by longer variable-frequency mobbing calls lasting 5–12 min. The duration of individual alarming and mobbing calls was 0.078 ± 0.014 s and 0.154 ± 0.041 s at frequency ranges of 520–1000 Hz and 690–3920 Hz, respectively. Alarming call duration was positively associated with group size. The alarm calls can trigger mobbing behavior in Hainan gibbons; this is a defense way of social animals, and first report among the primates’ species. The system of vocal alarm behavior described in this critically endangered species is simple and effective. PMID:27686623

Colorectal cancer (CRC) screening with a fecal immunochemical test (FIT) reduces CRC mortality; however, the acceptance rate of a colonoscopy in patients with a positive FIT was not high. The aim of this study was therefore to determine whether a telephone reminder call could increase the acceptance rate of colonoscopy in patients with a positive FIT. We performed FITs for asymptomatic participants aged 50 years or older. For patients with a positive FIT, a colonoscopy was recommended via mailing notification only (control group) or via a telephone reminder call after mailing notification (intervention group). The calls informed patients about the significance of a positive FIT and encouraged a colonoscopy following positive FITs. The FIT results were positive in 90 of 8,318 patients who received FITs. Fifty patients were advised to receive colonoscopy via mailing notification only, and 40 patients were advised via both a telephone reminder call and a mailing notification. The acceptance rate of colonoscopy was significantly higher in the intervention group than in the control group (p = 0.038). The lesion-detection rate for an advanced neoplasia was also significantly higher in the intervention group than in the control group (p = 0.046). According to multivariate logistic regression analysis, a telephone reminder was a significant determinant of colonoscopy acceptance in patients with a positive FIT (OR 4.33; 95% CI, 1.19-15.75; p = 0.026). Telephone reminder calls in addition to mailing notification improved the acceptance rate of colonoscopy in patients with a positive FIT.

Evidence for contact calls in fish: conspecific vocalisations and ambient soundscape influence group cohesion in a nocturnal species.

van Oosterom, L; Montgomery, J C; Jeffs, A G; Radford, C A

2016-01-11

Soundscapes provide a new tool for the study of fish communities. Bigeyes (Pempheris adspersa) are nocturnal planktivorous reef fish, feed in loose shoals and are soniferous. These vocalisations have been suggested to be contact calls to maintain group cohesion, however direct evidence for this is absent, despite the fact that contact calls are well documented for many other vertebrates, including marine mammals. For fish, direct evidence for group cohesion signals is restricted to the use of visual and hydrodynamic cues. In support of adding vocalisation as a contributing cue, our laboratory experiments show that bigeyes significantly increased group cohesion when exposed to recordings of ambient reef sound at higher sound levels while also decreasing vocalisations. These patterns of behaviour are consistent with acoustic masking. When exposed to playback of conspecific vocalisations, the group cohesion and vocalisation rates of bigeyes both significantly increased. These results provide the first direct experimental support for the hypotheses that vocalisations are used as contact calls to maintain group cohesion in fishes, making fish the evolutionarily oldest vertebrate group in which this phenomenon has been observed, and adding a new dimension to the interpretation of nocturnal reef soundscapes.

Many of the scientists working on the Elwha project have regularly met, since around 2004, for annual meetings. Loosely organized under the auspices of the Elwha Research and Elwha Nearshore consortia, the annual meetings have been informative for many reasons, including the sharing of study plans, field schedules, and preliminary results. It has been a great way for groups of physical scientists and groups of biologists to learn about the questions of interest to each group and to explore areas of overlap. In some cases, these meetings have spawned new collaborations, synergies, and research directions. In planning for the 2011 Elwha River Science Symposium, we sought to retain this espirit de corps, but realized that the start of dam removal heralded an important new phase of the project and called for an event that celebrated this special occasion. 

Psychometrics Matter in Health Behavior: A Long-term Reliability Generalization Study.

PubMed

Pickett, Andrew C; Valdez, Danny; Barry, Adam E

2017-09-01

Despite numerous calls for increased understanding and reporting of reliability estimates, social science research, including the field of health behavior, has been slow to respond and adopt such practices. Therefore, we offer a brief overview of reliability and common reporting errors; we then perform analyses to examine and demonstrate the variability of reliability estimates by sample and over time. Using meta-analytic reliability generalization, we examined the variability of coefficient alpha scores for a well-designed, consistent, nationwide health study, covering a span of nearly 40 years. For each year and sample, reliability varied. Furthermore, reliability was predicted by a sample characteristic that differed among age groups within each administration. We demonstrated that reliability is influenced by the methods and individuals from which a given sample is drawn. Our work echoes previous calls that psychometric properties, particularly reliability of scores, are important and must be considered and reported before drawing statistical conclusions.

Mechanisms of Pyroelectricity in Three- and Two-Dimensional Materials

Liu, Jian; Pantelides, Sokrates T.

2018-05-01

Pyroelectricity is a very promising phenomenon in three- and two-dimensional materials, but first-principles calculations have not so far been used to elucidate the underlying mechanisms. Here we report density-functional theory (DFT) calculations based on the Born-Szigeti theory of pyroelectricity, by combining fundamental thermodynamics and the modern theory of polarization. We find satisfactory agreement with experimental data in the case of bulk benchmark materials, showing that the so-called electron-phonon renormalization, whose contribution has been traditionally viewed as negligible, is important. We predict out-of-plane pyroelectricity in the recently synthesized Janus MoSSe monolayer and in-plane pyroelectricity in the group-IV monochalcogenide GeS monolayer. It is notable that the so-called secondary pyroelectricity is found to be dominant in GeS monolayer. The present work opens a theoretical route to study the pyroelectric effect using DFT and provides a valuable tool in the search for new candidates for pyroelectric applications.

An artificial reality environment for remote factory control and monitoring

Work has begun on the merger of two well known systems, VEOS (HITLab) and CLIPS (NASA). In the recent past, the University of Massachusetts Lowell developed a parallel version of NASA CLIPS, called P-CLIPS. This modification allows users to create smaller expert systems which are able to communicate with each other to jointly solve problems. With the merger of a VEOS message system, PCLIPS-V can now act as a group of entities working within VEOS. To display the 3D virtual world we have been using a graphics package called HOOPS, from Ithaca Software. The artificial reality environment we have set up contains actors and objects as found in our Lincoln Logs Factory of the Future project. The environment allows us to view and control the objects within the virtual world. All communication between the separate CLIPS expert systems is done through VEOS. A graphical renderer generates camera views on X-Windows devices; Head Mounted Devices are not required. This allows more people to make use of this technology. We are experimenting with different types of virtual vehicles to give the user a sense that he or she is actually moving around inside the factory looking ahead through windows and virtual monitors.

Demoralization and attitudes toward residents among certified nurse assistants in relation to job stressors and work resources: cultural diversity in long term care.

Ramirez, Mildred; Teresi, Jeanne; Holmes, Douglas

2006-01-01

Certified Nurse Assistants (CNAs) (n=104) caring for a probability sample of residents in 22 New York State nursing homes were interviewed, longitudinally, regarding work demands and stressors, support and training, and job-stress outcomes. Twenty-seven percent of CNAs reported pejorative name-calling by their residents. Hierarchical regression analyses showed that (a) increase in perceived pressure to complete tasks, (b) assignment size, and (c) attendance at support groups were associated with CNAs' demoralization at follow-up. A decrease in perceived racism and increased in-services about confused residents contributed to more positive attitudes toward residents. Examination of the quality of long-term care should include consideration of cultural diversity.

Factors Implicated in Safety-related Firefighter Fatalities.

Kahn, Steven A; Palmieri, Tina L; Sen, Soman; Woods, Jason; Gunter, Oliver L

Firefighting is wrought with risk, as 80-100 firefighters (FFs) die on the job each year in the United States. Many of the fatalities have been analyzed by the National Institute for Occupational Safety and Health (NIOSH) to determine contributing factors. The purpose of this study is to determine variables that put FFs at risk for potentially preventable workplace mortality such as use of personal protective equipment (PPE), seat belts, and appropriate training/fitness/clearance for duty. The NIOSH FF Fatality Database reports from 2009 to 2014 were analyzed. Data including age, gender, years on the job, weather, other calls on the same shift, and department type were compared between FFs who employed PPE, seat belts, or wellness/fitness and those who did not. A second group of FFs was determined by NIOSH to have inexperience, lack of training, or inappropriate clearance for duty implicated in their fatalities. Comparisons for the second group were between those whose department used training and safety-related standard operating protocols and those who did not. In 84/176 deaths, PPE/seat belts/fitness was implicated in the fatality. Lack of PPE was more likely on clear days (P = .03) but less likely on cloudy and windy days (P < .001). These FFs dying with lack of PPE had more time on the job in a single department, 18 vs 13 years (P = .03), and more time in a volunteer department, 17 vs 8 years (P < .01). Being deployed on another call during the same shift was associated with lack of PPE-34 vs 16% of those who had not been on another call (P = .005). Lack of training, experience, or medical clearance was implicated in fatalities for 100/176 FFs. FFs who worked in departments that lacked standard operating protocols for respirator fit testing, PPE, fitness testing, rapid intervention, medical clearance, safety/distress alarms, vehicle maintenance, or incident command were statistically more likely to have lack of experience/training/clearance implicated in the fatality. Good weather during a call and more years on the job, particularly in a volunteer department, are associated with FF mortality related to unsafe practices. These factors might create an air of complacency that puts FFs at risk for safety-related omissions. Having been on a recent call may create distraction or fatigue that puts FF at risk during subsequent calls. Lack of key safety-related protocols appears to put FFs at risk of mortality, and the risk may be increasing over time. Further study and prevention efforts from multidisciplinary groups are needed to better understand and combat this problem.

Recent advances in communication have enabled an underground interest group, unrestricted by geographic boarders, to evolve. The so-called pro-anorexia movement has a particular presence in the form of Internet discussion boards. This paper examines the potential impact of such online activity for those visiting these resources, for practitioners working with individuals who have anorexia, and for those conducting research into the condition. It contributes to the debate about this controversial development in the world of eating disorders.

Alien calculus and non perturbative effects in Quantum Field Theory

2016-12-01

In many domains of physics, methods for dealing with non-perturbative aspects are required. Here, I want to argue that a good approach for this is to work on the Borel transforms of the quantities of interest, the singularities of which give non-perturbative contributions. These singularities in many cases can be largely determined by using the alien calculus developed by Jean Écalle. My main example will be the two point function of a massless theory given as a solution of a renormalization group equation.

The Boston-area HASWIC Research Circle: an innovative participatory method for coloring in the picture of a special work environment.

Recent qualitative studies have investigated some of the hazards affecting women in non-traditional trades such as construction. However, one-time interactions among researcher participants, and between researchers and participants, in standard settings such as focus groups and interviews, cannot provide the time, space, and relationships to fully explore tradeswomen's in-depth knowledge of their work environment. This study applied a Scandinavian method called the Research Circle to convene a group of experienced women construction workers repeatedly over a period of two years so they could collaborate with researchers in explaining workplace issues. The results both validated and expanded upon previous findings about health and safety for women in construction, including gender discrimination, lack of access to sanitary facilities, retaliation for reporting hazards and injuries, and inadequate training and equipment. Especially important, findings illustrate some of the complex hierarchical social structures involved in both female and male construction workers responding to hazardous conditions.

Ergonomics and work organization: the relationship between tayloristic design and workers' health in banks and credit cards companies.

1999-01-01

The discussion developed in this paper is based on the results of an ergonomic work analysis carried out with attendants at call centers. Some critical issues and difficulties, like working pace, inadequate tools and workstations, and software inadequacies were detected in working situations. Operator-customer interactions are presented, attempting to put in evidence working constraints, working conditions, and their connection with health problems. The main conclusion is that serving clients, especially when the job is to provide information, is not a simple task, as information is not always available in the computerized system and is completely fragmented. The scope of workers' actions is very restricted and complicated and recurrent requests are redirected to others. Workers (individually or as groups) have limited possibilities to make adjustments to be able to give more adequate and personalized treatment to clients and, at the same time, to work in a less stressful environment. In periods of increased workload and work intensification, the situation is very much favorable to the incidence of health disorders, such as work related musculoskeletal disorders (WMSD) and others. Some suggestions to improve the work situation are discussed.

The polarized solid state target is an indispensable experimental tool to study single and double polarization observables at low intensity particle beams like tagged photons. It was one of the major components of the Crystal-Barrel experiment at ELSA. Besides the operation of the 'CB frozen spin target' within the experimental program of the Crystal-Barrel collaboration both collaborative groups of the D1 project, the polarized target group of the Ruhr Universität Bochum and the Bonn polarized target group, have made significant developments in the field of polarized targets within the CRC16. The Bonn polarized target group has focused its work on the development of technically challenging polarized solid target systems towards the so called '4π continuous mode polarized target' to operate them in combination with 4π-particle detection systems. In parallel, the Bochum group has developed various highly polarized deuterated target materials and high precision NMR-systems, in the meantime used for polarization experiments at CERN, JLAB and MAMI, too.

Nonadherence to prescription medications is a common and costly problem with multiple contributing factors, spanning the dimensions of individual behavior change, psychology, medicine, and health policy, among others. Addressing the problem of medication nonadherence requires strategic input from key experts in a number of fields. The Medication Adherence Alliance is a group of key experts, predominately from the US, in the field of medication nonadherence. Members include representatives from consumer advocacy groups, community health providers, nonprofit groups, the academic community, decision-making government officials, and industry. In 2015, the Medication Adherence Alliance convened to review the current landscape of medication adherence. The group then established three working groups that will develop recommendations for shifting toward solutions-oriented science. From the perspective of the Medication Adherence Alliance, the objective of this commentary is to describe changes in the US landscape of medication adherence, framing the evolving field in the context of a recent think tank meeting of experts in the field of medication adherence.

This article focuses on the psychosocial work environment of immigrant cleaners at a Danish workplace. Today, many cleaners working in Danish cleaning jobs are women from the established immigrant communities, but also labour migrants from the newer EU member states have found their way to the cleaning industry. Studies have drawn attention to immigrants' low position in the cleaning industry and their increased risk of work injuries. This article is based on a case study of an intervention called "Make a Difference" designed to improve the work environment among cleaners at a multi-ethnic workplace. We used semi-structured interviews, photo logs, observation and participation to investigate how the cleaners experienced their work environment. The cleaners reported an overload of heavy work, related to the concept of a classroom's "readiness for cleaning", and they expressed strained social relations and communication in addition to a lack of social recognition and invisibility at the workplace, a school. We analysed these psychosocial work environmental problems by investigating the different forms of social relationships and communication within the group of cleaners, and between the cleaners and the teachers and pupils at the school. Moreover, we discussed why the intervention, based on training of language and cleaning skills and social interaction, only partially improved the cleaners' psychosocial work environment problems. In this article, we argue that social divisions based on ethnicity between the new and the established group of cleaners, combined with their marginal position and poor work organisation at the school, reinforced the cleaners' experiences of psychosocial work environment problems. This article suggests that increased effort towards social inclusion at work and improved work organisation, especially for the new labour migrants from newer EU-countries, should be considered.

Next-generation sequencing (NGS) technologies have become much more efficient, allowing whole human genomes to be sequenced faster and cheaper than ever before. However, processing the raw sequence reads associated with NGS technologies requires care and sophistication in order to draw compelling inferences about phenotypic consequences of variation in human genomes. It has been shown that different approaches to variant calling from NGS data can lead to different conclusions. Ensuring appropriate accuracy and quality in variant calling can come at a computational cost. We describe our experience implementing and evaluating a group-based approach to calling variants on large numbers of whole human genomes. We explore the influence of many factors that may impact the accuracy and efficiency of group-based variant calling, including group size, the biogeographical backgrounds of the individuals who have been sequenced, and the computing environment used. We make efficient use of the Gordon supercomputer cluster at the San Diego Supercomputer Center by incorporating job-packing and parallelization considerations into our workflow while calling variants on 437 whole human genomes generated as part of large association study. We ultimately find that our workflow resulted in high-quality variant calls in a computationally efficient manner. We argue that studies like ours should motivate further investigations combining hardware-oriented advances in computing systems with algorithmic developments to tackle emerging 'big data' problems in biomedical research brought on by the expansion of NGS technologies.

Opening the door to coordination of care through teachable moments.

The challenge for care coordination is to identify members at a moment in time when they are receptive to intervention and provide the appropriate care management services. This manuscript describes a pilot program using inbound nurse advice calls from members to engage them in a care management program including disease management (DM). Annual medical claims diagnoses were used to identify members and their associated disease conditions. For each condition group for each year, nurse advice call data were used to calculate inbound nurse advice service call rates for each group. A pilot program was set up to engage inbound nurse advice callers in a broader discussion of their health concerns and refer them to a care management program. Among the program results, both the call rate by condition group and the correlation between average costs and call rates show that higher cost groups of members call the nurse advice service disproportionately more than lower cost members. Members who entered the DM programs through the nurse advice service were more likely to stay in the program than those who participated in the standard opt-in program. The results of this pilot program suggest that members who voluntarily call in to the nurse advice service for triage are at a "teachable moment" and highly motivated to participate in appropriate care management programs. The implication is that the nurse advice service may well be an innovative and effective way to enhance participation in a variety of care management programs including DM.

How Do Internal and External CSR Affect Employees' Organizational Identification? A Perspective from the Group Engagement Model

Hameed, Imran; Riaz, Zahid; Arain, Ghulam A.; Farooq, Omer

2016-01-01

The literature examines the impact of firms' corporate social responsibility (CSR) activities on employees' organizational identification without considering that such activities tend to have different targets. This study explores how perceived external CSR (efforts directed toward external stakeholders) and perceived internal CSR (efforts directed toward employees) activities influence employees' organizational identification. In so doing, it examines the alternative underlying mechanisms through which perceived external and internal CSR activities build employees' identification. Applying the taxonomy prescribed by the group engagement model, the study argues that the effects of perceived external and internal CSR flow through two competing mechanisms: perceived external prestige and perceived internal respect, respectively. Further, it is suggested that calling orientation (how employees see their work contributions) moderates the effects induced by these alternative forms of CSR. The model draws on survey data collected from a sample of 414 employees across five large multinationals in Pakistan. The results obtained using structural equation modeling support these hypotheses, reinforcing the notion that internal and external CSR operate through different mediating mechanisms and more interestingly employees' calling orientation moderates these relationships to a significant degree. Theoretical contributions and practical implications of results are discussed in detail. PMID:27303345

The literature examines the impact of firms' corporate social responsibility (CSR) activities on employees' organizational identification without considering that such activities tend to have different targets. This study explores how perceived external CSR (efforts directed toward external stakeholders) and perceived internal CSR (efforts directed toward employees) activities influence employees' organizational identification. In so doing, it examines the alternative underlying mechanisms through which perceived external and internal CSR activities build employees' identification. Applying the taxonomy prescribed by the group engagement model, the study argues that the effects of perceived external and internal CSR flow through two competing mechanisms: perceived external prestige and perceived internal respect, respectively. Further, it is suggested that calling orientation (how employees see their work contributions) moderates the effects induced by these alternative forms of CSR. The model draws on survey data collected from a sample of 414 employees across five large multinationals in Pakistan. The results obtained using structural equation modeling support these hypotheses, reinforcing the notion that internal and external CSR operate through different mediating mechanisms and more interestingly employees' calling orientation moderates these relationships to a significant degree. Theoretical contributions and practical implications of results are discussed in detail.

Therapeutic education (TE) is a practice developed over 40 years at an international level to give people with chronic illness the skills necessary to help them better manage their disease. The lengthening survival time of cancer patients as well as changes in the patient-caregiver relationship have contributed to the development of TE in oncologic diseases. Every year in France, about 1900 adolescents and young adults (15-25 years old) are diagnosed with cancer which is the second leading cause of death in this age group. The observed survival rates for these patients are lower when compared with children's. Some of the hypotheses put forward to explain this difference include a lack of constancy in care and a non-following treatment, as failure to adhere to therapies is common in this age group. "Go-AJA", an interdisciplinary national organization established in 2012, aims to improve the quality of care and treatment results for AYA living with cancer. Therapeutic education for AYA in oncology is an active working group of "Go-AJA" and intends to draw recommendations and to improve adapted communication on different education topics. Elaboration and preparation of TE programs by skilled multidisciplinary teams engaged in interactive educational actions is the first and most crucial step. The TE "Go-AJA" working group has federated pediatric and adult oncologists, nurses, psychologists, TE professionals, and resource patients, thanks to the commitment of professionals from the 8 national teams supported by the National Cancer Institute. Physical meetings and conference calls were organized from 2012 to 2015 to construct TE tools and programs for AYA with cancer. A competence referential was built and adapted to AYA population with cancer, after focused groups organized in 2 main oncology centers with on-therapy sarcoma patients and members of the multidisciplinary TE working group. Tools were validated and adapted to adolescents or young adults with cancer, to help in the 4 stages of TE: the "educational diagnosis" allowing the caregiver to better understand the patient in his life journey with the disease; the "therapeutic alliance" allowing to agree with the patient on his/her priorities; the "implementation" which is an action step: information, awareness, learning and psychosocial support. The final step called "assessment" allows the caregiver to take stock on the changes and difficulties with the patient. TE for AYA with cancer included individual and/or group sessions to improve self-care skills: knowledge about the disease (group sessions "what is cancer?" with use of microscopes to visualize sarcoma cells, and guided tours in a tumor research laboratory), and details about the treatment and its consequences (workshops about "management of febrile neutropenia"). Moreover, TE aimed to enrich the field of coping skills, in particular to improve the coordination and experience of cares between the different complex and varied network of care (group and/or individual sessions focused on physical rehabilitation, and adapted school/professional orientation). Regardless of the care system, care workers dedicated to AYA with cancer should use TE-specific actions to reinforce treatment participation and therapeutic relationships. This active multidisciplinary TE working group dedicated to AYA with cancer elaborated TE programs by skilled multidisciplinary teams engaged in interactive educational actions. After this work of a national TE organization, more studies using methodological tools are still required to evaluate the impact of such implemented programs on the treatment results and the quality of life.

2014-01-01

This study was conducted to investigate the association between emotional labor and dysmenorrhea among women working in sales and call centers in Seoul, South Korea. Working women in sales jobs and call centers in Seoul were interviewed face-to-face by well-trained interviewers. In total, 975 participants were analyzed in the final model. Emotional labor was measured using a constructed questionnaire with two components: an emotive effort component with three questions and an emotive dissonance component with five questions. To examine the association between emotional labor and dysmenorrhea, chi-squared tests and logistic regression were applied. The prevalence of dysmenorrhea among sales workers and call center workers were 43.0% and 61.1%, respectively. The adjusted odds ratios (OR) of emotive effort and emotive dissonance for dysmenorrhea in call center workers were 1.88 (95% confidence interval [CI], 1.07-3.28) and 1.72 (95% CI, 1.13-2.63), respectively. The adjusted OR of emotive effort and emotive dissonance for dysmenorrhea in sales workers were 1.71 (95% CI, 0.92-3.16) and 1.15 (95% CI, 0.67-1.98), respectively. Emotional labor was found to be associated with dysmenorrhea in call center workers. Further studies to investigate other factors, such as management strategies and the relationship between emotional labor and dysmenorrhea, are needed to support interventions to prevent dysmenorrhea that will further promote the quality of health and life of working women.

The effects of presentation pace and modality on learning a multimedia science lesson

NASA Astrophysics Data System (ADS)

Chung, Wen-Hung

Working memory is a system that consists of multiple components. The visuospatial sketchpad is the main entrance for visual and spatial information, whereas acoustic and verbal information is processed in the phonological loop. The central executive works as a coordinator of information from these two subsystems. Numerous studies have shown that working memory has a very limited capacity. Based on these characteristics of working memory, theories such as cognitive load theory and the cognitive theory of multimedia learning provide multimedia design principles. One of these principles is that when verbal information accompanying pictures is presented in audio mode instead of visually, learning can be more effective than if both text and pictures are presented visually. This is called the modality effect. However, some studies have found that the modality effect does not occur in some situations. In most experiments examining the modality effect, the multimedia is presented as system-paced. If learners are able to repeat listening as many times as they need, the superiority of spoken text over visual text seems lessened. One aim of this study was to examine the modality effect in a learner-controlled condition. This study also used the one-word-at-a-time technique to investigate whether the modality effect would still occur if both reading and listening rates were equal. There were 182 college students recruited for this study. Participants were randomly assigned to seven groups: a self-paced listening group, a self-paced reading group, a self text-block reading group, a general-paced listening group, a general-paced reading group, a fast-paced listening group, and a fast-paced reading group. The experimental material was a cardiovascular multimedia module. A three-by-two between-subjects design was used to test the main effect. Results showed that modality effect was still present but not between the self-paced listening group and the self text-block reading group. A post-study survey showed participants' different responses to the two modalities and their preferences as well. Results and research limitations are discussed and applications and future directions are also addressed.

Park, Haesuk; Adeyemi, Ayoade; Wang, Wei; Roane, Teresa E

To determine the impact of a telephone call reminder program provided by a campus-based medication therapy management call center on medication adherence in Medicare Advantage Part D (MAPD) beneficiaries with hypertension. The reminder call services were offered to eligible MAPD beneficiaries, and they included a live interactive conversation with patients to assess the use of their medications. This study used a quasi-experimental design for comparing the change in medication adherence between the intervention and matched control groups. Adherence, defined by proportion of days covered (PDC), was measured using incurred medication claims 6 months before and after the adherence program was implemented. A difference-in-differences approach with propensity score matching was used. After propensity score matching, paired samples included 563 patients in each of the intervention and control groups. The mean PDC (standard deviation) increased significantly during postintervention period by 17.3% (33.6; P <0.001) and 13.8% (32.3; P <0.001) for the intervention and the control groups, respectively; the greater difference-in-differences increase of 3.5% (36.3) in the intervention group over the control group was statistically significant (P = 0.022). A generalized estimating equation model adjusting for covariates further confirmed that the reminder call group had a significant increase in pre-post PDC (P = 0.021), as compared with the control group. Antihypertensive medication adherence increased in both reminder call and control groups, but the increase was significantly higher in the intervention group. A telephonic outreach program was effective in improving antihypertensive medication adherence in MAPD beneficiaries. Copyright © 2017 American Pharmacists Association®. Published by Elsevier Inc.

Industrial Robots For Measurement And Inspection Purposes

NASA Astrophysics Data System (ADS)

Ahlers, R.-J.

1989-02-01

The use of industrial robots for measuring and testing is becoming increasingly significant as a component of flexible production. In the early stages of their development robots were used mainly for monotonous and repetitive tasks such as handling and spot welding. Thanks to improvements in the precision with which they work and also in control and regulation technologies, it is possible today to employ robots as flexible, sensor-assisted and even "intellligent" tools for measuring and testing. As a result, however, much higher accuracy is demanded of the robots used for such purposes. In addition, robot measurement and acceptance test requirements have become more exacting. The present paper is based on recommendations that have been developed by cooperative work of the Association of German-Engineers (VDI/GMA). The appropriate working group is entitled "Industrial Robots -Measurement and Inspection". The author is the chairman of this working group. Apart from the technical equipment involved, the use of industrial robots for measuring purposes also calls for the devi-sing and programming of appropriate measuring strategies. In this context the planning and implementation of measuring projects have to be discussed along with software reliability and on-line/off-line programming strategies. Four different utilizations of robots for measuring and testing are presented and illustrated by examples.

Fatigue is common among physicians and adversely affects their performance. To identify strategies that attending physicians use when fatigued to maintain clinical performance in the intensive care unit (ICU). We conducted a qualitative study using focus groups and structured interviews of attending ICU physicians working in academic centers in Canada. In three focus group meetings, we engaged a total of 11 physicians to identify strategies used to prevent and cope with fatigue. In the focus groups, 21 cognitive strategies were identified and classified into 9 categories (minimizing number of tasks, using techniques to improve retention of details, using a structured approach to patient care, asking for help, improving opportunities for focusing, planning ahead, double-checking, adjusting expectations, and modulating alertness). In addition, various lifestyle strategies were mentioned as important in preventing fatigue (e.g., protecting sleep before call, adequate exercise, and limiting alcohol). Telephone interviews were then conducted (n = 15 physicians) with another group of intensivists. Structured questions were asked about the strategies identified in the focus groups that were most useful during ICU activities. In the interviews, the most useful and frequently used strategies were prioritizing tasks that need to be done immediately and postponing tasks that can wait, working systematically, using a structured approach, and avoiding distractions. ICU physicians reported using a variety of deliberate cognitive and lifestyle strategies to prevent and cope with fatigue. Given the low cost and intuitive nature of the majority of these strategies, further investigations should be done to better characterize their effectiveness in improving performance.

[Job demands and work-family conflict in a health care staff. The role of work shifts].

PubMed

Zito, Margherita; Colombo, Lara; Mura, Gabriella

2013-01-01

Work-family conflict (wfc), that originates from an incompatibility between the job and the family demands, is a very relevant topic in health care context, as suggested by NEXT study. Work overload and schedule organization are dimensions that can affect wfc, and particularly, studies indicate work shifts as one of its main determinants, as they limit the work-family balance and represent one of the prime risk factors for workers' health. The aim of this study was to detect the role of some job demands (both general and specific) and of schedule organization in determining the wfc experience, with particular attention to work shifts. Respondents to our questionnaire are 207 nurses of a north Italian public health organization. They are mostly women (92.8%) and their average age is 42. Data analysis shows that wfc is mostly influenced by work shifts, but also by work overload, cognitive load and by on-call availability. Staff working on shifts and on-call availability perceive a higher wfc than their colleagues without work shifts and on-call availability. The central role of work shifts in determining wfc suggests the need to act on schedule organization and on training programs for supervisors and workers.

The theme of well-being and discomfort at work has attracted increasing interest in recent years. The present study, according to Job Demands-Resources model (JD-R), inquires the effects of personal (optimism, internal locus of control) and organizational resources (job autonomy, supervisors and colleagues support) and general (work-to-family conflict, workload) and context specific demands (emotional dissonance) on emotional well-being and discomfort at work in call centre employees. This research was conducted through an online questionnaire, composed by measures present in scientific literature, filled out individually by call center agents (N = 507) of the same telecommunication firm. Data analysis (PASW 18) provides: descriptive statistics, correlations and multiple regressions. Personal and organizational resources improve emotional well-being at work, except for colleagues support. Optimism and supervisors support reduce emotional discomfort at work. Among organizational demands, work-family conflict and emotional dissonance increase emotional discomfort at work and, to a lesser extent, reduce the emotional well-being at work. The results, according to theoretical model, highlight the different role of demands and resources on emotional well-being and discomfort at work. The results suggest organizational politics and investments to promote emotional well-being at work, in particular training program to support emotional skills, training for supervisors, increasing job autonomy and support to work-family balance.

Vocational Psychology: Agency, Equity, and Well-Being.

PubMed

Brown, Steven D; Lent, Robert W

2016-01-01

The present review organizes the vocational psychology literature published between 2007 and 2014 into three overarching themes: Promoting (a) agency in career development, (b) equity in the work force, and (c) well-being in work and educational settings. Research on career adaptability, self-efficacy beliefs, and work volition is reviewed in the agency section, with the goal of delineating variables that promote or constrain the exercise of personal agency in academic and occupational pursuits. The equity theme covers research on social class and race/ethnicity in career development; entry and retention of women and people of color in science, technology, engineering, and math (STEM) fields; and the career service needs of survivors of domestic violence and of criminal offenders. The goal was to explore how greater equity in the work force could be promoted for these groups. In the well-being section, we review research on hedonic (work, educational, and life satisfaction) and eudaimonic (career calling, meaning, engagement, and commitment) variables, with the goal of understanding how well-being might be promoted at school and at work. Future research needs related to each theme are also discussed.

Schedule control and supervisor support for family and personal life are work resources that may help employees manage the work-family interface. However, existing data and designs have made it difficult to conclusively identify the effects of these work resources. This analysis utilizes a group-randomized trial in which some units in an information technology workplace were randomly assigned to participate in an initiative, called STAR, that targeted work practices, interactions, and expectations by (a) training supervisors on the value of demonstrating support for employees’ personal lives and (b) prompting employees to reconsider when and where they work. We find statistically significant, though modest, improvements in employees’ work-family conflict and family time adequacy and larger changes in schedule control and supervisor support for family and personal life. We find no evidence that this intervention increased work hours or perceived job demands, as might have happened with increased permeability of work across time and space. Subgroup analyses suggest the intervention brings greater benefits to employees more vulnerable to work-family conflict. This study advances our understanding of the impact of social structures on individual lives by investigating deliberate organizational changes and their effects on work resources and the work-family interface with a rigorous design.

The importance of doctors' working hours has gained significant attention with evidence suggesting long hours and fatigue may compromise the safety and wellbeing of both patients and doctors. This study aims to quantify the working hours of The Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) specialist trainees in order to better inform discussions of working hours and safety within our region. An anonymous, online survey of RANZCOG trainees was conducted. Demographic data were collected. The primary outcomes were: hours per week at work and hours per week on-call. Secondary outcomes included the frequency of long days (>12 h) and 24-h shifts, time spent studying, staff shortages and opinions regarding current rostering. Response rate was 49.5% (n = 259). Full-time trainees worked an average of 53.1 ± 10.0 h/week, with 11.6% working on-call. Long-day shifts were reported by 85.8% of respondents, with an average length of 14.2 h. Fifteen percent reported working 24-h shifts, with a median duration of uninterrupted sleep during this shift being 1-2 h. Trainees in New Zealand worked 7.0 h/week more than Australian trainees (P ≤0.001), but reported less on-call (P = 0.021). Trainees in Western Australia were more likely to work on-call (P ≤0.001) and 24-h shifts (P ≤0.001). While 53.1 h/week at work is similar to the average Australian hospital doctor, high rates of long days and 24-h shifts with minimal sleep were reported by RANZCOG trainees in this survey. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

The accentuation principle of figure-ground segregation and the downbeat illusion.

PubMed

Pinna, Baingio; Sirigu, Luca

2016-10-01

Pinna and Sirigu (2011) demonstrated a new principle of grouping, called the accentuation principle, stating that, all else being equal, elements tend to group in the same oriented direction of the discontinuous element placed within a whole set of continuous/homogeneous components. The discontinuous element behaves like an accent, i.e. a visual emphasis within the wholeness of components as shown in the next section. In this work, the accentuation principle has been extended to new visual domains. In particular, it is shown how this principle affects shape perception. Moreover several visual object attributes are also highlighted, among which orientation, spatial position, inner dynamics and apparent motion that determine the so-called organic segmentation and furthermore tend to induce figure-ground segregation. On the basis of the results of experimental phenomenology, the accentuation can be considered as a complex principle ruling grouping, figure-ground segregation, shape and meaning formation. Through a new musical illusion of downbeat, it is also demonstrated that this principle influences perceptual organization not only in space but also in time and, thus, in both visual and musical domains. This illusion can be heard in eight measures of Pagodes, a solo piano music by Claude Debussy (1862-1918), where a strong physical-perceptual discrepancy in terms of upbeats and downbeats inversion is strongly perceived in both staves.

Which types of televised anti-tobacco campaigns prompt more quitline calls from disadvantaged groups?

PubMed

Durkin, Sarah J; Wakefield, Melanie A; Spittal, Matthew J

2011-12-01

To examine the efficacy of different types of mass media ads in driving lower socio-economic smokers (SES) to utilize quitlines. This study collected all 33 719 calls to the Victorian quitline in Australia over a 2-year period. Negative binomial regressions examined the relationship between weekly levels of exposure to different types of anti-smoking ads and quitline calls, after adjusting for covariates. Interaction terms were added to determine whether relationships differed by SES. In total, smokers were exposed 88.39 times to anti-smoking ads over the 2-year period, as estimated by target audience ratings points. Higher emotion narrative ad exposure had the strongest association with quitline calls, increasing call rates by 13% for every additional ad exposure per week (per 100 points, rate ratio = 1.132, P = 0.001). Substantially, greater increases in calls to quitline from lower SES groups were observed when higher emotion narrative ads were on air compared with when other ad types were on air, and this advantage was not as strong among higher SES groups. Airing higher emotion narrative anti-smoking ads may contribute to reducing, but not eliminating, socio-economic disparities in calls to the quitline through maximizing the responses of the lower SES smokers.

Safety of union home care aides in Washington State.

Schoenfisch, Ashley L; Lipscomb, Hester; Phillips, Leslie E

2017-09-01

A rate-based understanding of home care aides' adverse occupational outcomes related to their work location and care tasks is lacking. Within a 30-month, dynamic cohort of 43 394 home care aides in Washington State, injury rates were calculated by aides' demographic and work characteristics. Injury narratives and focus groups provided contextual detail. Injury rates were higher for home care aides categorized as female, white, 50 to <65 years old, less experienced, with a primary language of English, and working through an agency (versus individual providers). In addition to direct occupational hazards, variability in workload, income, and supervisory/social support is of concern. Policies should address the roles and training of home care aides, consumers, and managers/supervisors. Home care aides' improved access to often-existing resources to identify, manage, and eliminate occupational hazards is called for to prevent injuries and address concerns related to the vulnerability of this needed workforce. © 2017 Wiley Periodicals, Inc.

Identification and analysis of unsatisfactory psychosocial work situations: a participatory approach employing video-computer interaction.

PubMed

Hanse, J J; Forsman, M

2001-02-01

A method for psychosocial evaluation of potentially stressful or unsatisfactory situations in manual work was developed. It focuses on subjective responses regarding specific situations and is based on interactive worker assessment when viewing video recordings of oneself. The worker is first video-recorded during work. The video is then displayed on the computer terminal, and the filmed worker clicks on virtual controls on the screen whenever an unsatisfactory psychosocial situation appears; a window of questions regarding psychological demands, mental strain and job control is then opened. A library with pictorial information and comments on the selected situations is formed in the computer. The evaluation system, called PSIDAR, was applied in two case studies, one of manual materials handling in an automotive workshop and one of a group of workers producing and testing instrument panels. The findings indicate that PSIDAR can provide data that are useful in a participatory ergonomic process of change.

Stay@Work: Participatory Ergonomics to prevent low back and neck pain among workers: design of a randomised controlled trial to evaluate the (cost-)effectiveness

2008-01-01

Background Low back pain (LBP) and neck pain (NP) are a major public health problem with considerable costs for individuals, companies and society. Therefore, prevention is imperative. The Stay@Work study investigates the (cost-)effectiveness of Participatory Ergonomics (PE) to prevent LBP and NP among workers. Methods In a randomised controlled trial (RCT), a total of 5,759 workers working at 36 departments of four companies is expected to participate in the study at baseline. The departments consisting of about 150 workers are pre-stratified and randomised. The control departments receive usual practice and the intervention departments receive PE. Within each intervention department a working group is formed including eight workers, a representative of the management, and an occupational health and safety coordinator. During a one day meeting, the working group follows the steps of PE in which the most important risk factors for LBP and NP, and the most adequate ergonomic measures are identified on the basis of group consensus. The implementation of ergonomic measures at the department is performed by the working group. To improve the implementation process, so-called 'ergocoaches' are trained. The primary outcome measure is an episode of LBP and NP. Secondary outcome measures are actual use of ergonomic measures, physical workload, psychosocial workload, intensity of pain, general health status, sick leave, and work productivity. The cost-effectiveness analysis is performed from the societal and company perspective. Outcome measures are assessed using questionnaires at baseline and after 6 and 12 months. Data on the primary outcome as well as on intensity of pain, sick leave, work productivity, and health care costs are collected every 3 months. Discussion Prevention of LBP and NP is beneficial for workers, employers, and society. If the intervention is proven (cost-)effective, the intervention can have a major impact on LBP and NP prevention and, thereby, on work disability prevention. Results are expected in 2010.

The screening program guidelines specify that the call back rate of women for additional imaging (positive mammogram) should not exceed 7% at initial screening, and 5% at subsequent screening. Materials and methods. Results in the Isere region (12%) have prompted a review of the correlation between the call back rate and indicators of quality (detection rate, sensitivity, specificity, positive predictive value) for the radiologists providing interpretations during that time period. Three groups of radiologists were identified: the group with call back rate of 10% achieved the best results (sensitivity: 92%, detection rate: 0.53%, specificity: 90%). The group with lowest call back rate (7.7%) showed insufficient sensitivity (58%). The last group with call back rate of 18.3%, showed no improvement in sensitivity (82%) and detection rate (0.53%), but showed reduced specificity (82%). The protocol update in 2001 does not resolve this problematic situation and national results continue to demonstrate a high percentage of positive screening mammograms. A significant increase in the number of positive screening examinations compared to recommended guidelines is not advantageous and leads to an overall decrease in the quality of the screening.

Researchers hypothesize that male loud calls play several roles in primate societies including in the context of intergroup spacing and spatial coordination. Field studies examining the behavioural correlates of vocalizations are essential to evaluate the function of these calls. This preliminary study, from July 2011 to January 2012, explores the behavioural contexts and correlates of male loud calls in a habituated group of red langurs (Presbytis rubicunda) in the Wehea Forest, East Kalimantan, Indonesia. In analysing 418 h of data collection, we find a total of 87 vocal behaviours, including bouts of multiple calls in rapid succession (i.e. calling events) and individual loud calls. In this sample, most vocal behaviour takes place in the morning with 59% of calling events occurring before 8.00 h. The mean rate of calling events is 0.12 events/h, and the mean rate of individual loud calls is 0.20 calls/h. The mean number of calling events per day is 1.31 (range: 0-4), and the mean number of individual loud calls per day is 2.81 (range: 0-13). The rate of calling events is highest in the context of intragroup conflict, followed by intergroup encounters, predator threat, group travel, and the highest number of individual loud calls occurred during intergroup encounters. Although these results are preliminary, they suggest that adult male loud calls among red langurs at Wehea may play a role in both intergroup spacing and social coordination, supporting the hypothesis that these calls can serve different functions. © 2016 S.

Social mobbing calls in common marmosets (Callithrix jacchus): effects of experience and associated cortisol levels.

PubMed

Clara, Elena; Tommasi, Luca; Rogers, Lesley J

2008-04-01

We compared the mobbing response to model snakes of two groups of captive-born common marmosets (Callithrix jacchus) differing in genetic relatedness, age and past experience. Mobbing vocalisations (tsik calls), other mobbing behaviour and attention to the stimulus were recorded for 2 min. intervals pre-exposure, during exposure to various stimuli and post-exposure. Marmosets in one group were vocally reactive to all stimuli, although more so to one particular stimulus resembling rearing snakes and modified images of it, whereas the marmosets in a younger and genetically unrelated group attended to the stimuli but made very few mobbing calls. The parent stock of the first group had suffered stress in early life and had developed a phobic response to a specific stimulus, which they had transmitted to their offspring. A third group, matching the older group in age range but genetically unrelated, was also found to be unresponsive to the stimulus that elicited the strongest response in the first group. Cortisol levels in samples of hair were assayed and a significant negative correlation was found between the number of tsik calls made during presentation of the stimuli and the cortisol level, showing that mobbing behaviour/behavioural reactivity is associated with low levels of physiological stress.

Adoption of residents' working time restrictions potentially undermines surgical training by reduction of operating room exposure. Simulation has been proposed as a way to acquire necessary skills in a laboratory environment but remains difficult to incorporate into training schedules. This study assessed whether residents working successive nights could acquire endovascular skills similar to colleagues working day shifts. This prospective observational cohort study recruited 20 junior residents, divided into day shift and night shift groups by their respective call schedule. After initial cognitive skills training, a validated renal artery stent module on an endovascular simulator was completed over a series of seven sequential shifts during 1 week. The primary outcome measure was serial technical skill assessments. Secondary measures comprised assessments of activity, cognitive performance, introspective fatigue, quality, and quantity of preceding sleep. Both groups demonstrated significant learning curves for total time at the first session median vs seventh session median (181 vs 564 seconds [P < .001]; night, 1399 vs 572 [P < .001]), fluoroscopy time (day, 702 vs 308 seconds, [P < .001]; night, 669 vs 313 [P < .001]), and contrast volume (day, 29 vs 13 mL [P < .001]; night, 40 vs 16 [P < .001]). Residents working day shifts reached plateau 1 day earlier in the above measures vs those on night duty. The night shift group walked more steps (P < .001), reviewed more patients (P < .001), performed worse on all cognitive assessments (P < .05), slept less (P < .05), had poorer quality of sleep (P = .001), and was more fatigued (P < .001) than the day shift group. Acquired skill was retained a week after completion of shifts. Technical skills training after night shift work enables acquisition of endovascular technical skills, although it takes longer than after day shift training. This study provides evidence for program directors to organize simulation-based training schedules for residents on night shift rotations. Copyright © 2011. Published by Mosby, Inc.

The Psychosocial Work Environment, Employee Mental Health and Organizational Interventions: Improving Research and Practice by Taking a Multilevel Approach.

2016-08-01

Although there have been several calls for incorporating multiple levels of analysis in employee health and well-being research, studies examining the interplay between individual, workgroup, organizational and broader societal factors in relation to employee mental health outcomes remain an exception rather than the norm. At the same time, organizational intervention research and practice also tends to be limited by a single-level focus, omitting potentially important influences at multiple levels of analysis. The aims of this conceptual paper are to help progress our understanding of work-related determinants of employee mental health by the following: (1) providing a rationale for routine multilevel assessment of the psychosocial work environment; (2) discussing how a multilevel perspective can improve related organizational interventions; and (3) highlighting key theoretical and methodological considerations relevant to these aims. We present five recommendations for future research, relating to using appropriate multilevel research designs, justifying group-level constructs, developing group-level measures, expanding investigations to the organizational level and developing multilevel approaches to intervention design, implementation and evaluation.

Incorporating biological information in sparse principal component analysis with application to genomic data.

PubMed

Li, Ziyi; Safo, Sandra E; Long, Qi

2017-07-11

Sparse principal component analysis (PCA) is a popular tool for dimensionality reduction, pattern recognition, and visualization of high dimensional data. It has been recognized that complex biological mechanisms occur through concerted relationships of multiple genes working in networks that are often represented by graphs. Recent work has shown that incorporating such biological information improves feature selection and prediction performance in regression analysis, but there has been limited work on extending this approach to PCA. In this article, we propose two new sparse PCA methods called Fused and Grouped sparse PCA that enable incorporation of prior biological information in variable selection. Our simulation studies suggest that, compared to existing sparse PCA methods, the proposed methods achieve higher sensitivity and specificity when the graph structure is correctly specified, and are fairly robust to misspecified graph structures. Application to a glioblastoma gene expression dataset identified pathways that are suggested in the literature to be related with glioblastoma. The proposed sparse PCA methods Fused and Grouped sparse PCA can effectively incorporate prior biological information in variable selection, leading to improved feature selection and more interpretable principal component loadings and potentially providing insights on molecular underpinnings of complex diseases.

Reconnaissance geology of the Precambrian rocks in the Bi'r Ghamrah quadrangle, Kingdom of Saudi Arabia

USGS Publications Warehouse

Overstreet, William C.; Whitlow, Jesse William

1972-01-01

Three sequences of volcanic and sedimentary rocks are identified in the Precambrian rocks of the Bi'r Ghamrah quadrangle at the eastern edge of the Precambrian Shield in central Saudi Arabia. The oldest sequence is called the Bi'r Khountina Group. It consists of conglomerate marble, andesite, and graywacke. Unconformably overlying this group is a sequence of graywacke with minor lava called the Murdama Group. In a small area in the southern part of the quadrangle, these rocks are unconformably overlain by rhyolitic tuff and rhyolite tentatively correlated with the Shammar Rhyolite. The older of these sedimentary and volcanic rocks were intruded by diorite and gabbro and by a large pluton of alkalic granite. A contact metamorphic aureole was formed in the Bi'r Khountina and Murdama Groups adjacent to the granite, and feeder dikes of the Sbmmmar Rhyolite(?) intrude the granite. The Bi'r Khountina Group is folded into a south-plunging asymmetrical anticlinorium, the west limb of which is repeated across northwest-trending faults. The Murdama Group appears to have been folded along the same axes, but the contact aureole against the alkalic granite and the imprint of the west-northwest striking Najd fault zone cause the rocks of the Murdama Group to appear to trend westward. Results of spectrographic and chemical analyses of wadi sand, heavy-mineral concentrates, and detrital magnetite show small anomalies. The ultramafic rocks intruded prior to the deposition of the Murdama Group are the source of anomalous chromium and lanthanum and of threshold nickel, scandium, and vanadium. The intrusive rocks younger than the Murdama Group are sources for anomalous lead and threshold silver, boron, barium, beryllium, zirconium, lanthanum, and tin. One small ancient working, probably opened for gold, is present, and at least four places in the Precambrian part of the quadrangle ere potentially favorable for gold, silver, and lead. Chromite is a potential resource in the northeastern part of the quadrangle.

A Call to Honesty: Extending Religious Priming of Moral Behavior to Middle Eastern Muslims

PubMed Central

Aveyard, Mark E.

2014-01-01

Two experiments with Middle Eastern participants explored the generalizability of prior research on religious priming and moral behavior to a novel cultural and religious context. Participants in Experiment 1 completed a sentence unscrambling task with religious or non-religious content (in Arabic) before taking an unsupervised math test on which cheating was possible and incentivized. No difference in honesty rates emerged between the two groups, failing to extend findings from previous research with similar stimuli. Experiment 2 tested the effects of the athan, the Islamic call to prayer, using the same design. This naturalistic religious prime produced higher rates of honesty (68%) compared to controls who did not hear the call to prayer (53%).These results raise the possibility that the psychological mechanisms used by religion to influence moral behavior might differ between religions and cultures, highlighting an avenue of exploration for future research. The experiments here also address two growing concerns in psychological science: that the absence of replications casts doubt on the reliability of original research findings, and that the Westernized state of psychological science casts doubt on the generalizability of such work.

Interprofessional education (IPE) is increasingly called upon to improve health care systems and patient safety. Our institution is engaged in a campus-wide IPE initiative. As a component of this initiative, a required online interprofessional patient-safety-focused course for a large group (300) of first-year medical, dental, and nursing students was developed and implemented. We describe our efforts with developing the course, including the use of constructivist and adult learning theories and IPE competencies to structure students' learning in a meaningful fashion. The course was conducted online to address obstacles of academic calendars and provide flexibility for faculty participation. Students worked in small groups online with a faculty facilitator. Thematic modules were created with associated objectives, online learning materials, and assignments. Students posted completed assignments online and responded to group members' assignments for purposes of group discussion. Students worked in interprofessional groups on a project requiring them to complete a root cause analysis and develop recommendations based on a fictional sentinel event case. Through project work, students applied concepts learned in the course related to improving patient safety and demonstrated interprofessional collaboration skills. Projects were presented during a final in-class session. Student course evaluation results suggest that learning objectives and content goals were achieved. Faculty course evaluation results indicate that the course was perceived to be a worthwhile learning experience for students. We offer the following recommendations to others interested in developing an in-depth interprofessional learning experience for a large group of learners: 1) consider a hybrid format (inclusion of some face-to-face sessions), 2) address IPE and broader curricular needs, 3) create interactive opportunities for shared learning and working together, 4) provide support to faculty facilitators, and 5) recognize your learners' educational level. The course has expanded to include students from additional programs for the current academic year.

Arrowheaded enhanced multivariance products representation for matrices (AEMPRM): Specifically focusing on infinite matrices and converting arrowheadedness to tridiagonality

NASA Astrophysics Data System (ADS)

2015-12-01

In this work, Enhanced Multivariance Products Representation (EMPR) approach which is a Demiralp-and-his- group extension to the Sobol's High Dimensional Model Representation (HDMR) has been used as the basic tool. Their discrete form have also been developed and used in practice by Demiralp and his group in addition to some other authors for the decomposition of the arrays like vectors, matrices, or multiway arrays. This work specifically focuses on the decomposition of infinite matrices involving denumerable infinitely many rows and columns. To this end the target matrix is first decomposed to the sum of certain outer products and then each outer product is treated by Tridiagonal Matrix Enhanced Multivariance Products Representation (TMEMPR) which has been developed by Demiralp and his group. The result is a three-matrix- factor-product whose kernel (the middle factor) is an arrowheaded matrix while the pre and post factors are invertable matrices decomposed of the support vectors of TMEMPR. This new method is called as Arrowheaded Enhanced Multivariance Products Representation for Matrices. The general purpose is approximation of denumerably infinite matrices with the new method.

Causal cognition in a non-human primate: field playback experiments with Diana monkeys.

PubMed

Zuberbühler, K

2000-09-14

Crested guinea fowls (Guttera pucherani) living in West African rainforests give alarm calls to leopards (Panthera pardus) and sometimes humans (Homo sapiens), two main predators of sympatric Diana monkeys (Cercopithecus diana). When hearing these guinea fowl alarm calls, Diana monkeys respond as if a leopard were present, suggesting that by default the monkeys associate guinea fowl alarm calls with the presence of a leopard. To assess the monkeys' level of causal understanding, I primed monkeys to the presence of either a leopard or a human, before exposing them to playbacks of guinea fowl alarm calls. There were significant differences in the way leopard-primed groups and human-primed groups responded to guinea fowl alarm calls, suggesting that the monkeys' response was not directly driven by the alarm calls themselves but by the calls' underlying cause, i.e. the predator most likely to have caused the calls. Results are discussed with respect to three possible cognitive mechanisms - associative learning, specialized learning programs, and causal reasoning - that could have led to causal knowledge in Diana monkeys.

Group Random Call Can Positively Affect Student In-Class Clicker Discussions.

PubMed

Knight, Jennifer K; Wise, Sarah B; Sieke, Scott

2016-01-01

Understanding how instructional techniques and classroom norms influence in-class student interactions has the potential to positively impact student learning. Many previous studies have shown that students benefit from discussing their ideas with one another in class. In this study of introductory biology students, we explored how using an in-class accountability system might affect the nature of clicker-question discussions. Clicker-question discussions in which student groups were asked to report their ideas voluntarily (volunteer call) were compared with discussions in which student groups were randomly selected to report their ideas (random call). We hypothesized that the higher-accountability condition (random call) would impress upon students the importance of their discussions and thus positively influence how they interacted. Our results suggest that a higher proportion of discussions in the random call condition contained exchanges of reasoning, some forms of questioning, and both on- and off-topic comments compared with discussion in the volunteer call condition. Although group random call does not impact student performance on clicker questions, the positive impact of this instructional approach on exchanges of reasoning and other features suggests it may encourage some types of student interactions that support learning. © 2016 J.

We recently introduced the efficacy safety score (ESS) as a new "call-out algorithm" for management of postoperative pain and side effects. In this study, we report the influence of ESS recorded hourly during the first 8 hours after surgery on the mobility degree, postoperative nonsurgical complications, and length of hospital stay (LOS). We randomized 1152 surgical patients into three groups for postoperative observation: (1) ESS group ( n = 409), (2) Verbal Numeric Rate Scale (VNRS) for pain group ( n = 417), and (3) an ordinary qualitative observation (Control) group ( n = 326). An ESS > 10 or VNRS > 4 at rest or a nurse's observation of pain or adverse reaction to analgesic treatment in the Control group served as a "call-out alarm" for an anaesthesiologist. We found no significant differences in the mobility degree and number of postoperative nonsurgical complications between the groups. LOS was significantly shorter with 12.7 ± 6.3 days (mean ± SD) in the ESS group versus 14.2 ± 6.2 days in the Control group ( P < 0.001). Postoperative ESS recording in combination with the possibility to call upon an anaesthesiologist when exceeding the threshold score might have contributed to the reductions of LOS in this two-centre study. This trial is registered with NCT02143128.

Relevance of β-delayed neutron data for reactor, nuclear physics and astrophysics applications

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

Kratz, Karl-Ludwig

Initially, yields (or abundances) and branching ratios of β-delayed neutrons (βdn) from fission products (P{sub n}-values) have had their main importance in nuclear reactor control. At that time, the six-group mathematical approximation of the time-dependence of βdn-data in terms of the so-called 'Keepin groups' was generally accepted. Later, with the development of high-resolution neutron spectroscopy, βdn data have provided important information on nuclear-structure properties at intermediate excitation energy in nuclei far from stability, as well as in nuclear astrophysics. In this paper, I will present some examples of the βdn-studies performed by the Kernchemie Mainz group during the past threemore » decades. This work has been recognized as an example of 'broad scientific diversity' which has led to my nomination for the 2014 Hans A. Bethe prize.« less

Culture cultivating culture: the four products of the meaning-made world.

PubMed

Carriere, Kevin R

2014-09-01

Culture, in a semiotic cultural psychology, is defined from the viewpoint of cultivation--the meaning making processes that give meaning to the world (Valsiner 2000, 2007a). However, the individual is not simply a process-machine in an empty world--there are both the external outcomes of meaning making (individual and group based) as well as the collective influence on the cultivation process. I argue to examine the cultivation process more completely, one must look at these external influences that catalyze future cultivation processes. By examining the power of the external (environmental Umwelten) and group-internal (myths, morals), a much greater understanding of the behavior of individuals can be accomplished beyond examining the individual's process of meaning making. Further work into examining the objects that affectively activate the individual as well as group action and meaning making is called for and examples of such studies are given.

2009-12-01

To examine the use of appreciative inquiry to promote the emergence of innovative ideas regarding the reorganization of health care services. With persistent employee dissatisfaction with work environments, experts are calling for radical changes in health care organizations. Appreciative inquiry is a transformational change process based on the premise that nurses and health care workers are accumulators and producers of knowledge who are agents of change. A multiple embedded case study was conducted in two interdisciplinary groups in outpatient cancer care to better understand the emergence and implementation of innovative ideas. The appreciative inquiry process and the diversity of the group promoted the emergence and adoption of innovative ideas. Nurses mostly proposed new ideas about work reorganization. Both groups adopted ideas related to interdisciplinary networks and collaboration. A forum was created to examine health care quality and efficiency issues in the delivery of cancer care. This study makes a contribution to the literature that examines micro systems change processes and how ideas evolve in an interdisciplinary context. The appreciative inquiry process created an opportunity for team members to meet and share their successes while proposing innovative ideas about care delivery. Managers need to support the implementation of the proposed ideas to sustain the momentum engendered by the appreciative inquiry process.

Revision of the Metallactus kollari species-group with a new diagnosis of the genus (Coleoptera: Chrysomelidae: Cryptocephalinae).

Sassi, Davide

2018-04-20

The genus Metallactus has been controversial since its introduction due to the ambiguous nature of the original diagnosis. This has caused some confusion in the taxonomy of Neotropical Pachybrachina. In this work the morphology of endophallus, which is useful for the characterization of species groups in several groups of Coleoptera, including Cryptocephalinae, has been analyzed. This has proven to be a good resource also in the taxonomic treatment of the species belonging to the genus Metallactus. After a careful survey on most of the species described so far, the endophallus shape in Metallactus turned out to be remarkably distinctive and very promising in the delimitation of species groups. The present work includes: a) a new diagnosis of the genus Metallactus on the basis of the aedeagal anatomy; b) the designation of the type species of the nominal genus; c) the revision of a first species-group of the genus, including the type species, hereinafter called Metallactus kollari species-group. Before this revision, catalogues had been reporting 13 species attributable to this group, in the present work three species have been synonymized and seven have been described as new to science. Therefore, the group includes 17 species. The species described as new are: Metallactus rileyi n. sp., M. bellatrix n. sp., M. longicornis n. sp.; M. londonpridei n. sp., M. regalini n. sp., M. bezoar n. sp., M. guarani n. sp. The new synonymies are as follows: Metallactus albipes Suffrian, 1866 (= M. nigrofasciatus Suffrian, 1866 n. syn.), M. albifrons Suffrian, 1866 (= M. flavofrontalis Jacoby, 1907 n. syn.), M. dodecastictus Suffrian, 1866 (= Griburius nigritarsis Jacoby, 1907 n. syn.). The lectotypes of all previously described species have been designated. The new synonymies, the name-bearing type fixations and designations and the nomenclatural acts have been critically discussed. An identification key for the species-group is also provided.

Limitation of duty hour regulations for pediatric resident wellness: A mixed methods study in Japan.

2016-09-01

Duty hour regulations have been placed in residency programs to address mental health concerns and to improve wellness. Here, we elucidate the prevalence of depressive symptoms after implementing an overnight call shift system and the factors associated with burnout or depression among residents.A sequential exploratory mixed methods study was conducted in a tertiary care pediatric and perinatal hospital in Tokyo, Japan. A total of 41 pediatric residents participated in the cross-sectional survey. We determined and compared the prevalence of depressive symptoms and the number of actual working hours before and after implementing the shift system. A follow-up focus-group interview with 4 residents was conducted to explore the factors that may trigger or prevent depression and burnout.Mean working hours significantly decreased from 75.2 hours to 64.9 hours per week. Prevalence of depressive symptoms remained similar before and after implementation of the shift system. Emotional exhaustion and depersonalization from the burnout scale were markedly associated with depression. High workload, stress intolerance, interpersonal difficulties, and generation gaps regarding work-life balance could cause burnout. Stress tolerance, workload monitoring and balancing, appropriate supervision, and peer support could prevent burnout.Although the overnight call shift system was effective in reducing working hours, its effectiveness in managing mental health issues among pediatric residents remains unclear. Resident wellness programs represent an additional strategy and they should be aimed at fostering peer support and improvement of resident-faculty interactions. Such an approach could be beneficial to the relationship between physicians of different generations with conflicting belief structures.

Future Career Plans and Practice Patterns of Canadian Obstetrics and Gynaecology Residents in 2011.

PubMed

Burrows, Jason; Coolen, Jillian

2016-01-01

The practice patterns of Obstetricians and Gynaecologists continue to evolve with each new generation of physicians. Diversifying subspecialties, changes in resident duty hours, job market saturation, and desire for work-life balance are playing stronger roles. Professional practice direction and needs assessment may be aided by awareness of future Obstetrics and Gynaecology physician career plans and expectations. The objective of this study was to determine the expected career plans and practice patterns of Canadian Obstetrics and Gynaecology residents following residency. The SOGC Junior Member Committee administered its third career planning survey to Canadian Obstetrics and Gynaecology residents electronically in December 2011. The data collected was statistically analyzed and compared to previous surveys. There were 183 responses giving a response rate of 43%. More than one half of all residents were considering postgraduate training (58%). Projected practice patterns included: 84% maintaining obstetrical practice, 60% locuming, and 50% job-sharing. The majority of residents expected to work in a 6 to 10 person call group (48%), work 3 to 5 call shifts per month (72%), work 41 to 60 hours weekly (69%), and practise in a city with a population greater than 500 000 (45%). Only 18% of residents surveyed were in favour of streaming residency programs in Obstetrics and Gynaecology. Canadian resident career plan and expected practice pattern assessment remains an important tool for aiding in resource allocation and strategic development of care and training in Obstetrics and Gynaecology in Canada.

Here we detail the big brown bat's adaptive temporal control over sonar call production for tracking prey, moving predictably or unpredictably, under different experimental conditions. We studied the adaptive control of vocal-motor behaviors in free-flying big brown bats, Eptesicus fuscus, as they captured tethered and free-flying insects, in open and cluttered environments. We also studied adaptive sonar behavior in bats trained to track moving targets from a resting position. In each of these experiments, bats adjusted the features of their calls to separate target and clutter. Under many task conditions, flying bats produced prominent sonar sound groups identified as clusters of echolocation pulses with relatively stable intervals, surrounded by longer pulse intervals. In experiments where bats tracked approaching targets from a resting position, bats also produced sonar sound groups, and the prevalence of these sonar sound groups increased when motion of the target was unpredictable. We hypothesize that sonar sound groups produced during flight, and the sonar call doublets produced by a bat tracking a target from a resting position, help the animal resolve dynamic target location and represent the echo scene in greater detail. Collectively, our data reveal adaptive temporal control over sonar call production that allows the bat to negotiate a complex and dynamic environment.

An agent-based model of dialect evolution in killer whales.

PubMed

Filatova, Olga A; Miller, Patrick J O

2015-05-21

The killer whale is one of the few animal species with vocal dialects that arise from socially learned group-specific call repertoires. We describe a new agent-based model of killer whale populations and test a set of vocal-learning rules to assess which mechanisms may lead to the formation of dialect groupings observed in the wild. We tested a null model with genetic transmission and no learning, and ten models with learning rules that differ by template source (mother or matriline), variation type (random errors or innovations) and type of call change (no divergence from kin vs. divergence from kin). The null model without vocal learning did not produce the pattern of group-specific call repertoires we observe in nature. Learning from either mother alone or the entire matriline with calls changing by random errors produced a graded distribution of the call phenotype, without the discrete call types observed in nature. Introducing occasional innovation or random error proportional to matriline variance yielded more or less discrete and stable call types. A tendency to diverge from the calls of related matrilines provided fast divergence of loose call clusters. A pattern resembling the dialect diversity observed in the wild arose only when rules were applied in combinations and similar outputs could arise from different learning rules and their combinations. Our results emphasize the lack of information on quantitative features of wild killer whale dialects and reveal a set of testable questions that can draw insights into the cultural evolution of killer whale dialects.

In response to a mandate in Section 118(c)(3) of the Water Quality Act of 1987, a program called Assessment and Remediation of Contaminated Sediments (ARCS) was established. Four technical work groups were formed. This paper details the research strategy of the Toxicity-Chemistry Work Group.The Work Group's general objectives are to develop survey methods and to map the degree of contamination and toxicity in bottom sediments at three study areas, which will serve as guidance for future surveys at other locations. A related objective is to use the data base that will be generated to calculate sediment quality concentrations by several methods. The information needed to achieve these goals will be collected in a series of field surveys at three areas: Saginaw Bay (MI), Grand Calumet River (IN), and Buffalo River (NY). Assessments of the extent of contamination and potential adverse effects of contaminants in sediment at each of these locations will be conducted by collecting samples for physical characterization, toxicity testing, mutagenicity testing, chemical analyses, and fish bioaccumulation assays. Fish populations will be assessed for tumors and external abnormalities, and benthic community structure will be analyzed. A mapping approach will use low-cost indicator parameters at a large number of stations, and will extrapolate by correlation from traditional chemical and biological studies at a smaller number of locations. Sediment toxicity testing includes elutriate, pore water and whole sediment bioassays in a three-tiered framework. In addition to the regular series of toxicity tests at primary mater stations, some stations are selected for a more extensive suite of tests.

Point counts from clustered populations: Lessons from an experiment with Hawaiian crows

1991-01-01

We designed an experiment to identify factors contributing most to error in counts of Hawaiian Crow or Alala (Corvus hawaiiensis) groups that are detected aurally. Seven observers failed to detect calling Alala on 197 of 361 3-min point counts on four transects extending from cages with captive Alala. A detection curve describing the relation between frequency of flock detection and distance typified the distribution expected in transect or point counts. Failure to detect calling Alala was affected most by distance, observer, and Alala calling frequency. The number of individual Alala calling was not important in detection rate. Estimates of the number of Alala calling (flock size) were biased and imprecise: average difference between number of Alala calling and number heard was 3.24 (.+-. 0.277). Distance, observer, number of Alala calling, and Alala calling frequency all contributed to errors in estimates of group size (P < 0.0001). Multiple regression suggested that number of Alala calling contributed most to errors. These results suggest that well-designed point counts may be used to estimate the number of Alala flocks but cast doubt on attempts to estimate flock size when individuals are counted aurally.

Responses of male cricket frogs (Acris crepitans) to attenuated and degraded advertisement calls.

We examined the vocal and non-vocal responses of male cricket frogs ( Acris crepitans ) to conspecific advertisement calls that had been attenuated or degraded by reducing the depth of amplitude modulation (AM). Both are characteristic of changes to the call as it is transmitted through natural habitats. As stimulus calls became more intense or less degraded, male cricket frogs gradually decreased their call rate and increased the number of call groups and pulse groups in their calls, changes indicative of increased aggressive interactions. At the higher intensities and lower degradation levels, the probability that males would shift to one of two non-vocal behavioral responses, attacking the perceived intruder or ceasing calling and abandoning the call site, gradually increased. The results show that differences in signal attenuation and AM degradation levels are perceived by males and trigger both vocal and non-vocal behavioral responses consistent with their use in evaluating the distance to a challenging male. Furthermore, the results indicate that the male responses are graded, increasing as intensity rises and degradation falls, and hierarchical, with vocal responses preceding behavioral responses over the range of intensities and degradation levels presented.

Family-activated medical emergency teams (MET) have the potential to improve the timely recognition of clinical deterioration and reduce preventable adverse events. Adoption of family-activated METs is hindered by concerns that the calls may substantially increase MET workload. We aimed to develop a reliable process for family activated METs and to evaluate its effect on MET call rate and subsequent transfer to the intensive care unit (ICU). The setting was our free-standing children's hospital. We partnered with families to develop and test an educational intervention for clinicians and families, an informational poster in each patient room and a redesigned process with hospital operators who handle MET calls. We tracked our primary outcome of count of family-activated MET calls on a statistical process control chart. Additionally, we determined the association between family-activated versus clinician-activated MET and transfer to the ICU. Finally, we compared the reason for MET activation between family calls and a 2:1 matched sample of clinician calls. Over our 6-year study period, we had a total of 83 family-activated MET calls. Families made an average of 1.2 calls per month, which represented 2.9% of all MET calls. Children with family-activated METs were transferred to the ICU less commonly than those with clinician MET calls (24% vs 60%, p<0.001). Families, like clinicians, most commonly called MET for concerns of clinical deterioration. Families also identified lack of response from clinicians and a dismissive interaction between team and family as reasons. Family MET activations were uncommon and not a burden on responders. These calls recognised clinical deterioration and communication failures. Family activated METs should be tested and implemented in hospitals that care for children.

Call centers are strategically and tactically important to many industries, including the healthcare industry. Call centers play a key role in acquiring and retaining customers. The ability to deliver high-quality and timely customer service without much expense is the basis for the proliferation and expansion of call centers. Call centers are unique blends of people and technology, where performance indicates combining appropriate technology tools with sound management practices built on key operational data. While the technology is fascinating, the people working in call centers and the skill of the management team ultimately make a difference to their companies.

The role of general practitioners in the pre hospital setting, as experienced by emergency medicine technicians: a qualitative study

PubMed Central

2014-01-01

Background Together with the ambulances staffed with emergency medical technicians (EMTs), general practitioners (GPs) on call are the primary resources for handling emergencies outside hospitals in Norway. The benefit of the GP accompanying the ambulance to pre-hospital calls is a matter of controversy in Norway. The purpose of the present study was to gain better insight into the EMT’s experiences with the role of the GPs in the care for critically ill patients in the pre-hospital setting. Methods We conducted four focus group interviews with EMTs at four different ambulance stations in Norway. Three of the stations were located at least 2 hours driving distance from the nearest hospital. The interviews were transcribed and analyzed using systematic text condensation. Results The EMTs described increasing confidence in emergency medicine during the last few years. However, they felt the need for GP participation in the ambulance when responding to a critically ill patient. The presence of GPs made the EMTs feel more confident, especially in unclear and difficult cases that did not fit into EMT guidelines. The main contributions of the GPs were described as diagnosis and decision-making. Bringing the physician to the patient shortened transportation time to the hospital and important medication could be started earlier. Several examples of sub-optimal treatment in the absence of the GP were given. The EMTs described discomfort with GPs not responding to the calls. They also experienced GPs responding to calls that did not function in the pre-hospital emergency setting. The EMTs reported a need for professional requirements for GPs taking part in out-of-hours work and mandatory interdisciplinary training on a regular basis. Conclusions EMTs want GPs to be present in challenging pre-hospital emergency settings. The presence of GPs is perceived as improving patient care. However, professional requirements are needed for GPs taking part in out-of-hours work, and the informants suggested a formalized area for training between EMTs and GPs on call. PMID:25145390

The knowledge about contents and arrangement of work-related measures in oncological rehabilitation is limited. The aim of the study was to develop a multimodal work-related module called Perspective Job for the oncological rehabilitation as well as to evaluate the process of development and the module itself. Perspective Job was developed within a rehabilitation team. For an examination of the process of development and of the module expert interviews with clinic employees and group interviews with patients were conducted. Group interviews were conducted before as well as after the implementation of Perspective Job to demonstrate changes in the rehabilitation from the patients point of view. Participants were oncological patients with substantial work-related problems. The module Perspective Job consists of work-related therapies as well as job trainings. The expert interviews illustrates: The process of development is valued as positive and meaningful by the rehabilitation team. Furthermore synergetic effects were used and the exchange of information and the communication within the team were promoted. The interviews with the patient emphasized that most perspective job therapies were classified as work-related and that an individual occupation-oriented care took place. The promoting exchanges of experience between the participants has been positively evaluated. In addition, they seemed to be well-prepared for the return to work. The development of a work-related module in the rehabilitation team is possible. The process was valued by the team members positively and promoted the multiprofessional cooperation. An occupationally oriented arrangement of the rehabilitation was solely perceived by the participants of Perspective Job, which felt better prepared to reintegrate into working life. The results emphasize the importance of teamwork for the development and implementation of work-related therapy modules for the oncological rehabilitation. © Georg Thieme Verlag KG Stuttgart · New York.

Although estimates suggest that, on average, some 30 per cent of all patients in general acute medical wards may have some form of dementia, Stirling University's Dementia Services Development Centre (DSDC), one of the leading international knowledge centres working to improve the lives of dementia sufferers, says progress in designing healthcare facilities that address such patients' needs has been 'patchy at best'. With the number of individuals living with dementia expected to double in the next 25 years, the DSDC has recently worked with Edinburgh-based architects, Burnett Pollock Associates, to develop an online resource that clearly illustrates, via 15 simulated 'dementia-friendly' healthcare 'spaces', some of the key principles to consider when designing effectively for this fast-growing group.

Many actors in global health are concerned with improving community health worker (CHW) policy and practice to achieve universal health care. Ethnographic research can play an important role in providing information critical to the formation of effective CHW programs, by elucidating the life histories that shape CHWs' desires for alleviation of their own and others' economic and health challenges, and by addressing the working relationships that exist among CHWs, intended beneficiaries, and health officials. We briefly discuss ethnographic research with 3 groups of CHWs: volunteers involved in HIV/AIDS care and treatment support in Ethiopia and Mozambique and Lady Health Workers in Pakistan. We call for a broader application of ethnographic research to inform working relationships among CHWs, communities, and health institutions.

How the all fruits salad creates sweeter futures in rural and remote mental health.

Lloyd, Robbie

2009-08-01

This paper outlines evidence of efficacious outcomes from mixing people living with diverse mental health challenges and/or intellectual disability. The intention was to show how mixing up people who are differently challenged can be efficacious in (re)habilitation terms. Two separate experiences of sharing personal narratives were involved, along with creative expressions in music, art and filming, combined with group gatherings providing discerning feedback for each other on members' day-to-day progress. After 12 months of 'open urban tribe' gatherings in Sydney, where participants formed a community of belonging, the model was adapted for use in Alice Springs. The original group developed a cycle of interactive ritual rhythms, and these became a special feature of their self-help, peer support approach. The Sydney project modelled community-based rehabilitation, and that process then informed the processes initiated in a rural, remote location. Regular whole tribe gatherings 'in the circle' combined with mentoring 'aunties and uncles'. By sharing stories and giving personal feedback on their progress, participants developed skills and confidence in self expression. Relating to each other and the group, and sharing creative expressions (group craft activities, dancing, small group performing) added depth to the experience of participants. Stories and celebrations were filmed, along with meetings to discuss progress and reflect on how to improve our process of sharing together. Ways for individuals to work on improving their life experiences were shared across the group, which generated a combination of forms of inquiry: supportive, collaborative and appreciative. These were combined with reflexive qualitative ethnographic recording by the researcher, to report and reflect on the whole process. The original 12 month open urban tribe formation (May 2004-June 2005) in Sydney led to regular gatherings where participants sought to come together and celebrate their being with each other until 2007. From that model further work was undertaken in Alice Springs in early 2008, applying a smaller version of this approach to a new community group. The narrative testimony and witnessing in the first group formed one element of what participants called 'the magic', which they commented on throughout their time together. It was their way of just being together (what this author calls their 'metaphorical energetic presence' alongside each other) that carried the power of this tribe's interactions. Mirroring and feeding back messages to each other that they belonged, that they had an identity, role and purpose together, was a key influence on wellness. That they were seen and loved by all participants was a vital element in the dynamic. These combined to create an effect dubbed 'Working the Business of Life' (WTBOL), a group sharing process providing practical feedback on how to maintain balance in life. By giving everyone a sense of being nurtured in their day-to-day lives, WTBOL showed that people of mixed consciousness can assist each other's healing, growth and development. The value in mixing people of different challenges was that it created a rich field of exchange of their beingness, and mutual appreciation and support. Each had compassion for the other's challenge, and this helped their own process of growing beyond their own challenges. The process has now been successfully applied in Peer Support Training Workshops for Consumers and Carers (November 2008 in Alice Springs). Arising from this work, the All Fruits Theory (AFT) argues that mixing people of diverse consciousness, in contexts of trust and safety with each other, can lead to enriching personal acknowledgement and a sense of belonging. By sharing stories, joining celebratory activities, it is possible to generate interactive rhythmical ritual cycles of companionship, celebration, communion and contemplation. The project thus stimulated purposeful motivation and intention to engage in new activities. Individual and group social and emotional wellbeing were enhanced by participating. The author argues that these results show that, just as biodiversity is essential for ecological sustainability, 'onto-diversity' (i.e. valuing diverse ways of being and knowing) is what is needed in rehabilitation settings. When applied across cultures, ethnicity, gender, class and capability differences, these wiser ways of knowing can lead to more sustainable ways of being (i.e. what this author calls 'onto-diversity for suss-tainability', playing on the modern slang term for 'sussing things out'--meaning gaining better understanding of what's really going on).

Advertisement-call modification, male competition and female preference in the bird-voiced treefrog Hyla avivoca

Senders and receivers influence dynamic characteristics of the signals used for mate attraction over different time scales. On a moment-to-moment basis, interactions among senders competing for a mate influence dynamic characteristics, whereas the preferences of receivers of the opposite gender exert an influence over evolutionary time. We observed and recorded the calling patterns of the bird-voiced treefrog Hyla avivoca, to assess how the dynamic characters of calls vary during interactions among groups of males in a chorus. This question was also addressed using playback experiments with males. Playback experiments with females showed how changes in dynamic call properties are likely to affect male mating success. Frogs calling in pairs, groups, or in response to playbacks produced longer calls than did isolated males. During call overlap, males often increased the duration of the silent interval (gaps) between the pulses of their calls so that the pulses of the calls of two neighbors interdigitated. This change resulted in increased variability of pulse rate, a traditionally static acoustic property; however, males also produced high proportions of non-overlapped calls in which variability in pulse rate was low and had species-typical values. Females preferred long calls to short and average-duration calls, and non-overlapped calls to overlapped calls. Given a choice between pairs of overlapped calls, females preferred pairs in which the proportion of overlap was low and pairs in which the pulses of such calls interdigitated completely. The observed patterns of vocal competition thus reflect the preferences of conspecific females, which have influenced the evolution of the calling behavior of H. avivoca. PMID:19789730

In this study, we assessed the mental health of Korean call center employees and investigated the potential predictors of their mental health status. A cross-sectional study using self-completing questionnaire was conducted for employees working for a credit card call center. A total of 306 call center employees completed the Depression Anxiety Stress Scale, the Emotion Labor Scale, and the Korean Occupational Stress Scale. The results showed that more than half of the participants reported high levels of depression, anxiety, and stress. A multiple regression analysis indicated that the total scores on the Depression Anxiety Stress Scale were predicted by perceived health, job satisfaction, job demands, organizational injustice, and emotional dissonance suggesting that, in the interest of improving the mental health of call center employees, their job demands and emotional dissonance should be reduced and the work environment be improved. Consideration should be given to providing routine assessments of mental health, including depression, anxiety, and stress, and the corresponding need for the development of an intervention program and other work-related policies that would protect employees from the risk of poor mental health outcomes. © 2017 John Wiley & Sons Australia, Ltd.

Calling Where It Counts: Subordinate Pied Babblers Target the Audience of Their Vocal Advertisements.

PubMed

Humphries, David J; Finch, Fiona M; Bell, Matthew B V; Ridley, Amanda R

2015-01-01

For territorial group-living species, opportunities to reproduce on the natal territory can be limited by a number of factors including the availability of resources within a territory, access to unrelated individuals, and monopolies on reproduction by dominant group members. Individuals looking to reproduce are therefore faced with the options of either waiting for a breeding opportunity to arise in the natal territory, or searching for reproductive opportunities in non-natal groups. In the cooperatively breeding Southern pied babbler, Turdoides bicolor, most individuals who achieve reproductive success do so through taking up dominant breeding positions within non-natal groups. For subordinate pied babblers therefore, searching for breeding opportunities in non-natal groups is of primary importance as this represents the major route to reproductive success. However, prospecting (where individuals leave the group to search for reproductive opportunities within other groups) is costly and individuals rapidly lose weight when not part of a group. Here we demonstrate that subordinate pied babblers adopt an alternative strategy for mate attraction by vocal advertisement from within their natal territories. We show that subordinates focus their calling efforts on the edges of their territory, and specifically near boundaries with neighbouring groups that have potential breeding partners (unrelated individuals of the opposite sex). In contrast to prospecting, calling individuals showed no body mass loss associated with this behaviour, suggesting that calling from within the group may provide a 'cheap' advertisement strategy. Additionally, we show that subordinates use information regarding the composition of neighbouring groups to target the greatest number of potential mating partners.

On the job training is where new employees called operators can start gaining knowledge on what they will be working on during their time in JSC. In these lessons I learned different things that are important ranging from thermal systems to electrical systems. While doing OJT classes the student will learn how to use a portable computer system which has displays that I also helped edit and clean up. The way you can also learn is by reading system briefs which describes the different systems. Due to the fact of a possible change in the ISS I updated a systems brief so that it can be relevant to what is actually on the space station. I was given a task that will help develop my skills and make myself better prepared for my future in the work field. The project that I worked on had me pulling real time data from the International Space Station. The Data I obtained from the space station will be correlated to battery performance. The group I will be working which is called REBA and we will take the telemetry and evaluate the data. I will be working with my mentor Ben Chislom and co-op Tyler along with the Pro team. They then will put this data into a graph so that they can get the discrepancies and find a way to improve the battery performance. The first weeks I read familiarization books that informed me how the ISS works, how it was built, and the systems that are used to keep the station working. This project is going to benefit NASA by finding out how electricity is being used on the ISS and enabling us to see how it can be used more efficiently. This way we can operate the ISS without wasting power. While conducting research that goes on inside the space station knowing all electricity is being used efficiently.

Medical directors of long-term care facilities: preventing another physician shortage?

The long-term care (LTC) sector in Canada is expanding, but little attention has been given to medical human resources in this area. Our objective was to seek LTC medical directors' opinions about medical services in LTC and about strategies for recruitment and retention. Mailed survey. Long-term care facilities and nursing homes. Seven hundred five medical directors of LTC facilities across Canada were identified from the Canadian Healthcare Association database. Responses to open- and closed-ended questions and to Likert-type scales. The response rate was 55%. The average age of medical directors was 54 years. Most had started work in LTC because of a vacant position, as opposed to self-perceived skills or training. Most (75.3%) reported satisfaction with their role as medical directors, but 82.7% believed that there was a significant shortage of physicians working in LTC, and 42% had seriously considered leaving their positions. Major sources of satisfaction identified were clinical, especially working with older patients and improving care. Important sources of dissatisfaction were remuneration for LTC work, on-call coverage, and excessive paperwork. Directors suggested increases to fee schedules as the main recruitment and retention strategy, and many believed that increasing exposure to LTC during residency would increase recruitment. Development of larger on-call groups for coverage and alternative methods of remuneration were not cited as important factors. Most did not believe that working in a teaching nursing home would increase their satisfaction. Directors did not think the use of nurse practitioners would alleviate concerns about shortages of physicians. Medical directors of LTC facilities are aging, and many are considering leaving their work in LTC. Without an increase in the number of physicians willing to work in LTC institutions, the current shortage of LTC physicians could increase in the near future. Medical directors' responses to questions could help guide strategies to recruit and retain physicians. Future areas of research should include the perspectives of physicians who are not medical directors and of family medicine residents.

Background Human error and deficient non-technical skills (NTSs) among providers of ALS in helicopter emergency medical services (HEMS) is a threat to patient and operational safety. Skills can be improved through simulation-based training and assessment. Objective To document the current level of simulation-based training and assessment of seven generic NTSs in crew members in the Norwegian HEMS. Methods A cross-sectional survey, either electronic or paper-based, of all 207 physicians, HEMS crew members (HCMs) and pilots working in the civilian Norwegian HEMS (11 bases), between 8 May and 25 July 2012. Results The response rate was 82% (n=193). A large proportion of each of the professional groups lacked simulation-based training and assessment of their NTSs. Compared with pilots and HCMs, physicians undergo statistically significantly less frequent simulation-based training and assessment of their NTSs. Fifty out of 82 (61%) physicians were on call for more than 72 consecutive hours on a regular basis. Of these, 79% did not have any training in coping with fatigue. In contrast, 72 out of 73 (99%) pilots and HCMs were on call for more than 3 days in a row. Of these, 54% did not have any training in coping with fatigue. Conclusions Our study indicates a lack of simulation-based training and assessment. Pilots and HCMs train and are assessed more frequently than physicians. All professional groups are on call for extended hours, but receive limited training in how to cope with fatigue. PMID:25344577

The Pliocene Citronelle Formation of the Gulf Coastal Plain

USGS Publications Warehouse

Matson, George Charlton

1916-01-01

In the spring of 1910 the writer, working under the direction of T. Wayland Vaughan, geologist in charge of Coastal Plain investigations, undertook a study of the later Tertiary formations of the Gulf Coastal Plain. According to the plans outlined before the work was begun, the beds that had formerly been grouped under the names Lafayette formation and Grand Gulf formation were to be studied with a view to their possible separation into more satisfactory stratigraphic units that might be correlated with other formations which, on the basis of their fossils, had been assigned to their proper positions in the geologic time scale. The original plan included a study of the post-Vicksburgian Tertiary deposits from western Florida to Mississippi River and correlations with formations previously recognized in Florida, southern Alabama, and Louisiana. This plan was subsequently modified to extend the investigation as far west as Sabine River. The field work was interrupted and the office work was delayed by calls for geologic work in other areas, so that the preparation of the reports could not be begun until the spring of 1914.

Possible ancestral structure in human populations.

Plagnol, Vincent; Wall, Jeffrey D

Determining the evolutionary relationships between fossil hominid groups such as Neanderthals and modern humans has been a question of enduring interest in human evolutionary genetics. Here we present a new method for addressing whether archaic human groups contributed to the modern gene pool (called ancient admixture), using the patterns of variation in contemporary human populations. Our method improves on previous work by explicitly accounting for recent population history before performing the analyses. Using sequence data from the Environmental Genome Project, we find strong evidence for ancient admixture in both a European and a West African population (p approximately 10(-7)), with contributions to the modern gene pool of at least 5%. While Neanderthals form an obvious archaic source population candidate in Europe, there is not yet a clear source population candidate in West Africa.

Building successful coalitions for promoting advance care planning.

Advance care planning (ACP) has had few successful initiatives. This qualitative study explores the challenges and successes of an advance care planning coalition in Wisconsin called Life Planning 2000 using key informant interviews (n = 24) and grounded theory. Major themes included: commitment (the need for leadership, recruitment of key members, and funding); cohesiveness (disparate groups collaborating toward a common purpose), and outcomes (shift in paradigm from signing documents to process of advanced care planning, new-found collaborative relationships, and educational tool development). Coalitions need to define short-, intermediate-, and long-term goals that result in measurable outcomes and an evaluation process. Resources must be commensurate with goals. Strong leadership, paid staff adequate funding, and the collaboration of diverse groups working toward common goals are the basic requirements of a successful coalition.

Getting from Here to There: The Roles of Policy Makers and Principals in Increasing Science Teacher Quality

2010-04-01

In this study we investigate how federal and state policy makers, and school principals are working to improve science teacher quality. Interviews, focused discussions, and policy documents serve as the primary data source. Findings suggest that both policy makers and principals prioritize increasing incentives for teachers entering the science teaching profession, providing professional development for new teachers, and using students’ data to evaluate and improve instruction. Differences between the two leadership groups emerged in terms of the grain size and practicality of their concerns. Our findings indicate that the complexity of educational challenges to improve science teacher quality call for the co-construction of policy by multiple constituent groups including school principals, federal and state policy makers, and science education researchers.

Symposium on teacher stress. Occupational stress among vocational teachers.

Pithers, R T; Fogarty, G J

1995-03-01

There is a widespread belief that work related stress among teachers is serious, with implications for teachers' health status and performance. The difficulty with interpreting data on teacher stress is that the measuring instruments used are often neither standardised nor sometimes focused on stressors pertinent to the occupational roles of teachers. This study, therefore, uses a recently developed test instrument called the Occupational Stress Inventory (OSI) which concisely measures occupational stress, strain and coping resources. Data were obtained, using the OSI, from a group of vocational teachers and compared to a group of professional non-teachers. Overall the results showed a significantly higher level of teacher stress, although only one of 10 stress and strain measures contributed to this effect. The implications for teachers, in terms of occupational role, are discussed.

Distress Calls of a Fast-Flying Bat (Molossus molossus) Provoke Inspection Flights but Not Cooperative Mobbing

Many birds and mammals produce distress calls when captured. Bats often approach speakers playing conspecific distress calls, which has led to the hypothesis that bat distress calls promote cooperative mobbing. An alternative explanation is that approaching bats are selfishly assessing predation risk. Previous playback studies on bat distress calls involved species with highly maneuverable flight, capable of making close passes and tight circles around speakers, which can look like mobbing. We broadcast distress calls recorded from the velvety free-tailed bat, Molossus molossus, a fast-flying aerial-hawker with relatively poor maneuverability. Based on their flight behavior, we predicted that, in response to distress call playbacks, M. molossus would make individual passing inspection flights but would not approach in groups or approach within a meter of the distress call source. By recording responses via ultrasonic recording and infrared video, we found that M. molossus, and to a lesser extent Saccopteryx bilineata, made more flight passes during distress call playbacks compared to noise. However, only the more maneuverable S. bilineata made close approaches to the speaker, and we found no evidence of mobbing in groups. Instead, our findings are consistent with the hypothesis that single bats approached distress calls simply to investigate the situation. These results suggest that approaches by bats to distress calls should not suffice as clear evidence for mobbing. PMID:26353118

Objective Nonadherence reduces glaucoma treatment efficacy. Motivational interviewing (MI) is a well-studied adherence intervention, but has not been tested in glaucoma. Reminder interventions also may improve adherence. Design 201 patients with glaucoma or ocular hypertension were urn-randomized to receive MI delivered by an ophthalmic technician (OT), usual care, or a minimal behavioral intervention (reminder calls). Main Outcome Measures Outcomes included electronic monitoring with Medication Event Monitoring System (MEMS) bottles, two self-report adherence measures, patient satisfaction, and clinical outcomes. Multilevel modeling was used to test differences in MEMS results by group over time; ANCOVA was used to compare groups on other measures. Results Reminder calls increased adherence compared to usual care based on MEMS, p = .005, and self-report, p = .04. MI had a nonsignificant effect but produced higher satisfaction than reminder calls, p = .007. Treatment fidelity was high on most measures, with observable differences in behavior between groups. All groups had high baseline adherence that limited opportunities for change. Conclusion Reminder calls, but not MI, led to better adherence than usual care. Although a large literature supports MI, reminder calls might be a cost-effective intervention for patients with high baseline adherence. Replication is needed with less adherent participants.

The after-hours or on-call component of a paediatrician's work has implications for their spouse and family. Little is known about the specifics and extent of this impact. We aimed to understand the potential positive and negative impacts of this important aspect of a paediatrician's work. The spouses (nine female and one male) of 10 practising paediatricians, who are providing care in a variety of hospital settings within New Zealand, were interviewed using an open-questioning technique. Interviews were analysed by a qualitative line-by-line thematic method in order to categorise the perceived impact of their spouses' on-call work on themselves and their families. Participants reported multiple effects of after-hours on-call on themselves, their paediatrician partners and their families. Negative themes included sleep deprivation, restrictions on life-style and living location (specifically home proximity to hospital), spousal sacrifice, intimacy and communication challenges, and diminished quality time with children. Positive themes highlighted professional rewards, financial security and adaptability. Themes were consistent across age, length of relationship, spousal occupation and the presence of children. The intensity of these impacts for our participants appeared to vary depending on the degree of marital support and frequency of on-call. After-hours on-call has a generally negative impact on paediatricians' spouses and families. © 2013 The Authors.

Echolocating Big Brown Bats, Eptesicus fuscus, Modulate Pulse Intervals to Overcome Range Ambiguity in Cluttered Surroundings

Big brown bats (Eptesicus fuscus) emit trains of brief, wideband frequency-modulated (FM) echolocation sounds and use echoes of these sounds to orient, find insects, and guide flight through vegetation. They are observed to emit sounds that alternate between short and long inter-pulse intervals (IPIs), forming sonar sound groups. The occurrence of these strobe groups has been linked to flight in cluttered acoustic environments, but how exactly bats use sonar sound groups to orient and navigate is still a mystery. Here, the production of sound groups during clutter navigation was examined. Controlled flight experiments were conducted where the proximity of the nearest obstacles was systematically decreased while the extended scene was kept constant. Four bats flew along a corridor of varying widths (100, 70, and 40 cm) bounded by rows of vertically hanging plastic chains while in-flight echolocation calls were recorded. Bats shortened their IPIs for more rapid spatial sampling and also grouped their sounds more tightly when flying in narrower corridors. Bats emitted echolocation calls with progressively shorter IPIs over the course of a flight, and began their flights by emitting shorter starting IPI calls when clutter was denser. The percentage of sound groups containing 3 or more calls increased with increasing clutter proximity. Moreover, IPI sequences having internal structure become more pronounced when corridor width narrows. A novel metric for analyzing the temporal organization of sound sequences was developed, and the results indicate that the time interval between echolocation calls depends heavily on the preceding time interval. The occurrence of specific IPI patterns were dependent upon clutter, which suggests that sonar sound grouping may be an adaptive strategy for coping with pulse-echo ambiguity in cluttered surroundings.

Unifi nootropics from the lab to the web: a story of academic (and industrial) shortcomings.

This paper is a review of the work of my former academic group of research in the past 15 years, in the field of cognition enhancers (also called nootropics) that identified two very potent molecules: Unifiram and Sunifiram that for a variety of reasons were not protected by a patent. Some 12 years after their disclosure (2000) I casually found that on the web, there were dozens of sites offering Unifiram and Sunifiram as drugs that improve cognition in healthy individuals even if only few preclinical studies were done and their long-term toxicity was unknown.

Approximately 100 years ago Eugen Bleuler published the most significant contribution to psychiatry by conceptualizing the term schizophrenia as a diagnostic entity. In modern diagnostic manuals Bleuler's concept is only reflected in subordinated criteria, i.e. the negative symptoms. On the occasion of the anniversary of Bleuler's essential publication, the present work aims to exemplify the differences in diagnostic concepts and it will be illustrated that Bleuler's intention to establish his so-called basic symptom as a guideline for diagnostics has to be considered as failed from a present day viewpoint.

Method and apparatus for obtaining stack traceback data for multiple computing nodes of a massively parallel computer system

DOEpatents

Gooding, Thomas Michael; McCarthy, Patrick Joseph

2010-03-02

A data collector for a massively parallel computer system obtains call-return stack traceback data for multiple nodes by retrieving partial call-return stack traceback data from each node, grouping the nodes in subsets according to the partial traceback data, and obtaining further call-return stack traceback data from a representative node or nodes of each subset. Preferably, the partial data is a respective instruction address from each node, nodes having identical instruction address being grouped together in the same subset. Preferably, a single node of each subset is chosen and full stack traceback data is retrieved from the call-return stack within the chosen node.

Inclusive research with people with intellectual disabilities is growing internationally but with few studies examining its feasibility. In undertaking a national study exploring what life was like in Ireland for people with intellectual disabilities, a community of practice was developed involving a core group of co-researchers: five people with intellectual disabilities, four university researchers and three service support staff. An additional cadre of 15 co-researchers with intellectual disabilities was recruited to undertake data gathering and analysis with 23 focus groups involving 168 participants. The research experience was documented through oral feedback, progress reports, minutes and a project review. The key learning is documented arising from the setting up of an inclusive advisory group and implementation of each of six research steps. The study demonstrates feasibility and the added value of university co-researchers recruiting and developing skills together with co-researchers with intellectual disabilities. Topics for further research and development are identified. This paper tells you about how people with intellectual disabilities worked with a group of university researchers. Both groups were called co-researchers and together they ran 23 focus groups across Ireland. People with intellectual disabilities talked about their lives and what could make them better. They said they needed to have a good place to live; a job; enough money; relationships; and acceptance as respected citizens. The university co-researchers wrote about what it was like doing research together and how people with intellectual disabilities joined the advisory group; decided on the questions; ran focus groups; and presented findings. Together they grew into a community of researchers where the university co-researchers shared their research skills and people with intellectual disabilities shared what it was like living with a disability. They both saw great value in working together and plan to work more to make this type of research happen. © 2013 John Wiley & Sons Ltd.

Early sepsis attention is a standard of care in many institutions and the role of different specialists is well recognized. However, the impact of a telephone call from a specialist in Clinical Microbiology upon blood cultures request has not been assessed to the best of our knowledge. We performed telephone calls followed by an interview with physicians and nurses in charge of adult patients (> 18 years old) whose blood cultures had just been received in the Microbiology Laboratory in a tertiary hospital. Patients were randomly classified in 2 different groups: group A (telephone call performed) and group B (no telephone call). At the end of the telephonic intervention, recommendations on the use of microbiology and biochemical tests as well as on the management and antibiotic therapy of sepsis were made if required. We included 300 patients. Of those fulfilling standard criteria of sepsis, 30.3% of the nurses and 50% of the physicians immediately recognized it. Advice to optimize the use of biochemical and microbiological tests was provided in 36% of the cases and to improve antimicrobial therapy in 57.6%. The median number of days of antibiotic use in groups A and B were, respectively, 6 days (IQR: 2-12) vs 9 days (IQR: 4-16) P = 0.008 and the median number of prescribed daily doses of antimicrobials (6 [IQR: 3-17] vs 10 [IQR: 5-22] P = 0.016) were lower in group A. We estimate a reduction, only in the use of antibiotic, of 1.8 million Euros per year. A telephone call with management advice, immediately after the arrival of blood cultures in the Microbiology Laboratory improves the recognition of sepsis and the use of diagnostic resources and reduces antimicrobial consumption and expenses.

There are relatively few studies on the association between disturbances in drinking water services and symptoms of gastrointestinal (GI) illness. Health Call Centres data concerning GI illness may be a useful source of information. This study investigates if there is an increased frequency of contacts with the Health Call Centre (HCC) concerning gastrointestinal symptoms at times when there is a risk of impaired water quality due to disturbances at water works or the distribution network. The study was conducted in Gothenburg, a Swedish city with 0.5 million inhabitants with a surface water source of drinking water and two water works. All HCC contacts due to GI symptoms (diarrhoea, vomiting or abdominal pain) were recorded for a three-year period, including also sex, age, and geocoded location of residence. The number of contacts with the HCC in the affected geographical areas were recorded during eight periods of disturbances in the water works (e.g. short stops of chlorine dosing), six periods of large disturbances in the distribution network (e.g. pumping station failure or pipe breaks with major consequences), and 818 pipe break and leak repairs over a three-year period. For each period of disturbance the observed number of calls was compared with the number of calls during a control period without disturbances in the same geographical area. In total about 55, 000 calls to the HCC due to GI symptoms were recorded over the three-year period, 35 per 1000 inhabitants and year, but much higher (>200) for children <3 yrs of age. There was no statistically significant increase in calls due to GI illness during or after disturbances at the water works or in the distribution network. Our results indicate that GI symptoms due to disturbances in water works or the distribution network are rare. The number of serious failures was, however limited, and further studies are needed to be able to assess the risk of GI illness in such cases. The technique of using geocoded HCC data together with geocoded records of disturbances in the drinking water network was feasible. Copyright © 2013 Elsevier Ltd. All rights reserved.

Are cellular phone blocking applications effective for novice teen drivers?

2015-09-01

Distracted driving is a significant concern for novice teen drivers. Although cellular phone bans are applied in many jurisdictions to restrict cellular phone use, teen drivers often report making calls and texts while driving. The Minnesota Teen Driver Study incorporated cellular phone blocking functions via a software application for 182 novice teen drivers in two treatment conditions. The first condition included 92 teens who ran a driver support application on a smartphone that also blocked phone usage. The second condition included 90 teens who ran the same application with phone blocking but which also reported back to parents about monitored risky behaviors (e.g., speeding). A third control group consisting of 92 novice teen drivers had the application and phone-based software installed on the phones to record cellular phone (but not block it) use while driving. The two treatment groups made significantly fewer calls and texts per mile driven compared to the control group. The control group data also demonstrated a higher propensity to text while driving rather than making calls. Software that blocks cellular phone use (except 911) while driving can be effective at mitigating calling and texting for novice teen drivers. However, subjective data indicates that some teens were motivated to find ways around the software, as well as to use another teen's phone while driving when they were unable to use theirs. Cellular phone bans for calling and texting are the first step to changing behaviors associated with texting and driving, particularly among novice teen drivers. Blocking software has the additional potential to reduce impulsive calling and texting while driving among novice teen drivers who might logically know the risks, but for whom it is difficult to ignore calling or texting while driving.

2018-01-01

Independent component analysis (ICA) has been widely applied to identify intrinsic brain networks from fMRI data. Group ICA computes group-level components from all data and subsequently estimates individual-level components to recapture inter-subject variability. However, the best approach to handle artifacts, which may vary widely among subjects, is not yet clear. In this work, we study and compare two ICA approaches for artifacts removal. One approach, recommended in recent work by the Human Connectome Project, first performs ICA on individual subject data to remove artifacts, and then applies a group ICA on the cleaned data from all subjects. We refer to this approach as Individual ICA based artifacts Removal Plus Group ICA (IRPG). A second proposed approach, called Group Information Guided ICA (GIG-ICA), performs ICA on group data, then removes the group-level artifact components, and finally performs subject-specific ICAs using the group-level non-artifact components as spatial references. We used simulations to evaluate the two approaches with respect to the effects of data quality, data quantity, variable number of sources among subjects, and spatially unique artifacts. Resting-state test-retest datasets were also employed to investigate the reliability of functional networks. Results from simulations demonstrate GIG-ICA has greater performance compared to IRPG, even in the case when single-subject artifacts removal is perfect and when individual subjects have spatially unique artifacts. Experiments using test-retest data suggest that GIG-ICA provides more reliable functional networks. Based on high estimation accuracy, ease of implementation, and high reliability of functional networks, we find GIG-ICA to be a promising approach. PMID:26859308

To highlight the importance of friendships to young people with psychosis, and the need for clinical interventions to help maintain peer relationships during illness. To structure a research agenda for developing evidence-based interventions with friends. An argument is developed through a narrative review of (i) the proven efficacy of family interventions, and (by comparison) a relative absence of friend-based interventions; (ii) the particular primacy of friendships and dating for young people, and typical effects of exclusion; and (iii) reduced friendship networks and dating experiences in psychosis, in pre-, during and post-psychosis phases, also links between exclusion and psychosis. We put forward a model of how poor friendships can potentially be a causal and/or maintenance factor for psychotic symptoms. Given this model, our thesis is that interventions aiming to maintain social networks can be hugely beneficial clinically for young people with psychosis. We give a case study to show how such an intervention can work. We call for 'friends interventions' for young people with psychosis to be developed, where professionals directly work with a young person's authentic social group to support key friendships and maintain social continuity. An agenda for future research is presented that will develop and test theoretically driven interventions. © 2014 Wiley Publishing Asia Pty Ltd.

A comparison of calls subjected to a malpractice claim versus 'normal calls' within the Swedish healthcare direct: a case-control study.

2014-10-03

The purpose of this study is to compare communication patterns in calls subjected to a malpractice claim with matched controls. In many countries, telephone advice nursing is patients' first contact with healthcare. Telenurses' assessment of callers' symptoms and needs are based on verbal communication only, and problems with over-triage and under-triage have been reported. A total sample of all reported medical errors (n=33) during the period 2003-2010 within Swedish Healthcare Direct was retrieved. Corresponding calls were thereafter identified and collected as sound files from the manager in charge at the respective call centres. For technical reasons, calls from four of the cases were not possible to retrieve. For the present study, matched control calls (n=26) based on the patient's age, gender and main symptom presented by the caller were collected. Male patients were in majority (n=16), and the most common reasons for calling were abdominal pain (n=10) and chest pain (n=5). There were statistically significant differences between the communication in the cases and controls: telenurses used fewer open-ended medical questions (p<0.001) in the cases compared to the control calls; callers provided telenurses with more medical information in the control calls compared to the cases (p=0.001); and telenurses used more facilitation and patient activation activities in the control calls (p=0.034), such as back-channel response (p=0.001), compared to the cases. The present study shows that telenurses in malpractice claimed calls used more closed-ended questioning compared to those in control calls, who used more open-ended questioning and back-channel response, which provided them with richer medical descriptions and more information from the caller. Hence, these communicative techniques are important in addition to solid medical and nursing competence and sound decision aid systems. Published by the BMJ Publishing Group Limited.

Williams syndrome ([WS], 7q11.23 hemideletion) and 7q11.23 duplication syndrome (Dup7) show contrasting syndromic symptoms. However, within each group there is considerable interindividual variability in the degree to which these phenotypes are expressed. Though software exists to identify areas of copy number variation (CNV) from commonly-available SNP-chip data, this software does not provide non-diploid genotypes in CNV regions. Here, we describe a method for identifying haploid and triploid genotypes in CNV regions, and then, as a proof-of-concept for applying this information to explain clinical variability, we test for genotype-phenotype associations. Blood samples for 25 individuals with WS and 13 individuals with Dup7 were genotyped with Illumina-HumanOmni5M SNP-chips. PennCNV and in-house code were used to make genotype calls for each SNP in the 7q11.23 locus. We tested for association between the presence of aortic arteriopathy and genotypes of the remaining (haploid in WS) or duplicated (triploid in Dup7) alleles. Haploid calls in the 7q11.23 region were made for 99.0% of SNPs in the WS group, and triploid calls for 98.8% of SNPs in those with Dup7. The G allele of SNP rs2528795 in the ELN gene was associated with aortic stenosis in WS participants (p < 0.0049) while the A allele of the same SNP was associated with aortic dilation in Dup7. Commonly available SNP-chip information can be used to make haploid and triploid calls in individuals with CNVs and then to relate variability in specific genes to variability in syndromic phenotypes, as demonstrated here using aortic arteriopathy. This work sets the stage for similar genotype-phenotype analyses in CNVs where phenotypes may be more complex and/or where there is less information about genetic mechanisms.

A 360 degrees evaluation of a night-float system for general surgery: a response to mandated work-hours reduction.

2004-01-01

New York State Code 405 and societal/political pressure have led the RRC and ACGME to mandate strict limitations on resident work hours. In an attempt to meet these limitations, we have switched from the previous Q3 call schedule to a specialized night float (NF) system, the continuity-care system (CCS). The purpose of this CCS is to maximize resident duty time spent on direct patient care, operative experience, and outpatient clinics, while reducing duty hours spent on performing routine tasks and call coverage. The implementation of the CCS is the fundamental step in the restructuring of our residency program. In addition to a change in the call system, we added physician assistants to aid in performing some service tasks. We performed a 360 degrees evaluation of this work in progress. In May 2002, the standard Q3 call system was abolished on the general surgery services at the New York Presbyterian Hospital, Columbia campus. Two dedicated teams were created to provide day and night coverage, a day continuity-care team (DCT) and a night continuity-care team (NCT). The DCTs, consisting of PGY1-5 residents, provide daily in-house coverage from 6 AM to 5 PM with no regular weekday night-call responsibilities. The DCT residents provide Friday night, Saturday, and daytime Sunday call coverage 3 to 4 days per month. The NCT, consisting of 5 PGY1-5 residents, provides nightly continuous care, 5 PM to 6 AM, Sunday through Thursday, with no other weekend call responsibilities. This system creates a schedule with less than 80 duty hours per week, on average, with one 24-hour period off a week, one complete weekend off per month, and no more than 24 hours of consecutive duty time. After 1 year of use, the system was evaluated by a 360 degrees method in which residents, residents' spouses, nurses, and faculty were surveyed using a Likert-type scale. Statistical significance was calculated using the Student t-test. Patient satisfaction was measured both by internal review of a patient complaint database as well as by the Press Ganey patient satisfaction surveys. Twenty-one residents, 10 residents' spouses, 11 general surgery faculty, and 16 nurses were surveyed. Statistically significant findings included reduced resident fatigue noted by all groups (residents, p = 0.01; resident spouses, p = 0.05; faculty, p < 0.0001; nurses, p < 0.0001). Further, residents reported more time for sleep at home (p = 0.0005) and more time for independent reading (p = 0.01). Residents' spouses reported increased availability for family events (p = 0.01). Nurses reported increased availability of residents (p = 0.0002), shorter times to physician identification of patient problems (p = 0.0086), improved resident-nursing communications (p = 0.0096), and increased ease of nursing duties (p < 0.0001). Faculty were the only responders who felt that continuity of patient care suffered with the new system (p = 0.02). The Press Ganey review showed improvement in the quality of care rendered as perceived by patients. The institution of a specialized NF or CCS for in-house coverage of general surgical services in a large metropolitan university hospital has had initial success in meeting the mandated changes in resident work hours. The CCS reduced resident fatigue, improved quality of resident life, and improved patient care as judged by patients and nurse.

Background We recently introduced the efficacy safety score (ESS) as a new “call-out algorithm” for management of postoperative pain and side effects. In this study, we report the influence of ESS recorded hourly during the first 8 hours after surgery on the mobility degree, postoperative nonsurgical complications, and length of hospital stay (LOS). Methods We randomized 1152 surgical patients into three groups for postoperative observation: (1) ESS group (n = 409), (2) Verbal Numeric Rate Scale (VNRS) for pain group (n = 417), and (3) an ordinary qualitative observation (Control) group (n = 326). An ESS > 10 or VNRS > 4 at rest or a nurse's observation of pain or adverse reaction to analgesic treatment in the Control group served as a “call-out alarm” for an anaesthesiologist. Results We found no significant differences in the mobility degree and number of postoperative nonsurgical complications between the groups. LOS was significantly shorter with 12.7 ± 6.3 days (mean ± SD) in the ESS group versus 14.2 ± 6.2 days in the Control group (P < 0.001). Conclusion Postoperative ESS recording in combination with the possibility to call upon an anaesthesiologist when exceeding the threshold score might have contributed to the reductions of LOS in this two-centre study. This trial is registered with NCT02143128. PMID:28855800

Electrical impedance tomography (EIT) has undergone 30 years of development. Functional chest examinations with this technology are considered clinically relevant, especially for monitoring regional lung ventilation in mechanically ventilated patients and for regional pulmonary function testing in patients with chronic lung diseases. As EIT becomes an established medical technology, it requires consensus examination, nomenclature, data analysis and interpretation schemes. Such consensus is needed to compare, understand and reproduce study findings from and among different research groups, to enable large clinical trials and, ultimately, routine clinical use. Recommendations of how EIT findings can be applied to generate diagnoses and impact clinical decision-making and therapy planning are required. This consensus paper was prepared by an international working group, collaborating on the clinical promotion of EIT called TRanslational EIT developmeNt stuDy group. It addresses the stated needs by providing (1) a new classification of core processes involved in chest EIT examinations and data analysis, (2) focus on clinical applications with structured reviews and outlooks (separately for adult and neonatal/paediatric patients), (3) a structured framework to categorise and understand the relationships among analysis approaches and their clinical roles, (4) consensus, unified terminology with clinical user-friendly definitions and explanations, (5) a review of all major work in thoracic EIT and (6) recommendations for future development (193 pages of online supplements systematically linked with the chief sections of the main document). We expect this information to be useful for clinicians and researchers working with EIT, as well as for industry producers of this technology. Published by the BMJ Publishing Group Limited.

Objective We aimed to understand the characteristics of U.S. workers in non-standard employment arrangements, and to assess associations between job stress and Health-related Quality of Life (HRQL) by employment arrangement. Background As employers struggle to stay in business under increasing economic pressures, they may rely more on non-standard employment arrangements, thereby increasing the pool of contingent workers. Worker exposure to job stress may vary by employment arrangement. Excessive exposure to stressors at work is considered to be a potential health hazard, and may adversely affect health and HRQL. Methods We used the Quality of Worklife (QWL) module which supplemented the General Social Survey (GSS) in 2002, 2006, 2010, and 2014. GSS is a biannual, nationally representative cross-sectional survey of U.S. households that yields a representative sample of the civilian, non-institutionalized, English-speaking, U.S. adult population. The QWL module assesses an array of psychosocial working conditions and quality of work life topics among GSS respondents. We used pooled QWL responses from 2002 to 2014 by only those who reported being employed at the time of the survey. After adjusting for sampling probabilities, including subsampling for non-respondents and correcting for the number of adults in the household, 6005 respondents were included in our analyses. We grouped respondents according to their employment arrangement, including: (i) independent contractors (contractor), (ii) on call workers (on call), (iii) workers paid by a temporary agency (temporary), (iv) workers who work for a contractor (under contract), or (v) workers in standard employment arrangements (standard). Respondents were further grouped into those who were stressed and those who were not stressed at work. Descriptive population prevalence rates were calculated by employment arrangement for select demographic and organizational characteristics, psychosocial working conditions, work-family balance, and health and well-being outcomes. We also assessed the effect of employment arrangement on job stress, and whether job stress was associated with the number of reported unhealthy days and days with activity limitations. These two health and well-being outcomes capture aspects of worker HRQL. Results Our results underscored the importance of employment arrangement in understanding job stress and associated worker health and well-being outcomes. Between 2002 and 2014, the prevalence of workers in non-standard employment arrangements increased from 19% to 21%; however, the observed trend did not monotonically increase during that period. Compared with workers in standard arrangements, independent contractors and on call workers were significantly less likely to report experiencing job stress. For workers in standard arrangements and for contractors, we observed significant association between perceived job stress and reported unhealthy days. We observed a similar association for reported days with activity limitations, for workers in standard and temporary arrangements. Conclusion The major contribution of our study was to highlight the differences in job stress and HRQL by employment arrangement. Our results demonstrated the importance of studying each of these employment arrangements separately and in depth. Furthermore, employment arrangement was an important predictor of job stress, and compared with non-stressed workers, stressed workers across all employment arrangements reported more unhealthy days and more days with activity limitations.

With whom to dine? Ravens' responses to food-associated calls depend on individual characteristics of the caller

Upon discovering food, common ravens, Corvus corax, produce far-reaching ‘haa’ calls or yells, which are individually distinct and signal food availability to conspecifics. Here, we investigated whether ravens respond differently to ‘haa’ calls of known and unknown individuals. In a paired playback design, we tested responses to ‘haa’ call sequences in a group containing individually marked free-ranging ravens. We simultaneously played call sequences of a male and a female raven in two different locations and varied familiarity (known or unknown to the local group). Ravens responded strongest to dyads containing familiar females, performing more scan flights above and by perching in trees near the respective speaker. Acoustic analysis of the calls used as stimuli showed no sex-, age- or familiarity-specific acoustic cues, but highly significant classification results at the individual level. Taken together, our findings indicate that ravens respond to individual characteristics in ‘haa’ calls, and choose whom to approach for feeding, i.e. join social allies and avoid dominant conspecifics. This is the first study to investigate responses to ‘haa’ calls under natural conditions in a wild population containing individually marked ravens. PMID:25598542

2009-01-01

The Accreditation Council for Graduate Medical Education (ACGME) work-hour restrictions have prompted many surgical training programs to adopt a night-float resident coverage system (NF). Dissatisfaction with NF prompted us to transition to a rotating junior resident call model (Q4) with 24-hour call shifts at the outset of the 2007-2008 academic year. We performed a prospective study to determine the influence of this transition on resident education, morale, and quality of life, as well as on ACGME work rule compliance and American Board of Surgery In-Training Examination (ABSITE) scores. Residents were surveyed after 1 year of NF and again 1 year after the introduction of Q4. Responses to a series of statements about the influence of the call model (NF or Q4) on educational opportunities and morale were solicited. The survey used a 5-point Likert response scale (1 = complete disagreement to 5 = complete agreement). Median values of participant responses were calculated and compared using the Wilcoxon rank-sum test. Compliance with ACGME work rules, ABSITE scores, and operative case logs from the 2006-2007 and 2007-2008 academic years were also compared. Residents were significantly more enthusiastic about Q4 compared with NF, particularly when asked about the influence these systems had on morale (median response = 4.0 [Q4] compared with 2.0 [NF]; p = 0.001) and engagement of residents by the teaching faculty (median response = 4.0 [Q4] compared with 1.0 [NF]; p = 0.001). Case logs revealed a similar operative experience for first-year residents irrespective of the call schedule (p = 0.51). Excellent compliance with ACGME work rules was maintained as reflected by the percentage of monthly 80-hour violations per resident months worked (3% [Q4] compared with 0.7% [NF]). No difference was observed in the ABSITE scores of first-year residents (a mean percentile point increase of 1 was found after the introduction of Q4). Educational opportunities, compliance with ACGME work rules, and ABSITE scores can be preserved despite a transition from NF to Q4. Residents greatly prefer a rotating call schedule.

Multidisciplinary Responses to the Sexual Victimization of Children: Use of Control Phone Calls.

This descriptive study addresses the question of the value of one-party consent phone calls regarding the sexual victimization of children. The authors reviewed 4 years of experience with children between the ages of 3 and 18 years selected for the control phone calls after a forensic interview by the New York State Police forensic interviewer. The forensic interviewer identified appropriate cases for control phone calls considering New York State law, the child's capacity to make the call, the presence of another person to make the call and a supportive residence. The control phone call process has been extremely effective forensically. Offenders choose to avoid trial by taking a plea bargain thereby dramatically speeding up the criminal judicial and family court processes. An additional outcome of the control phone call is the alleged offender's own words saved the child from the trauma of testifying in court. The control phone call reduced the need for children to repeat their stories to various interviewers. A successful control phone call gives the child a sense of vindication. This technique is the only technique that preserves the actual communication pattern between the alleged victim and the alleged offender. This can be of great value to the mental health professionals working with both the child and the alleged offender. Cautions must be considered regarding potential serious adverse effects on the child. The multidisciplinary team members must work together in the control phone call. The descriptive nature of this study did not allow the authors adequate demographic data, a subject that should be addressed in future prospective study.

Article 2 contains guiding principles and policies which call for 1) ensuring equal access to resources, employment, and services; 2) minimizing inequities and disparities; 3) preventing sex discrimination in the work place; and 4) protecting children from abuse or harmful employment. Article 10 covers personal, family, tribal, and property relations and recognizes customary law in these areas (including marriage) among members of indigenous groups or cultural communities. Article 9 deals with ancestral domain and ancestral lands and directs the Regional Government to protect the same. Article 16 discusses social justice and welfare and provides for a living wage, profit-sharing schemes, and occupational safety. In the area of health care, this article calls for establishment of a primary health care delivery system, health education, training for health care workers, establishment of a food and drug regulatory system, research into traditional medicine, financing schemes to lower health care costs, and protection of vulnerable groups. Housing programs will be instituted where needed, women's status will be enhanced, child care support systems will be established, and women will receive education in regard to their rights and responsibilities to correct stereotypes.

A group matrix representation relevant to scales of measurement of clinical disease states via stratified vectors.

Sawamura, Jitsuki; Morishita, Shigeru; Ishigooka, Jun

2016-02-09

Previously, we applied basic group theory and related concepts to scales of measurement of clinical disease states and clinical findings (including laboratory data). To gain a more concrete comprehension, we here apply the concept of matrix representation, which was not explicitly exploited in our previous work. Starting with a set of orthonormal vectors, called the basis, an operator Rj (an N-tuple patient disease state at the j-th session) was expressed as a set of stratified vectors representing plural operations on individual components, so as to satisfy the group matrix representation. The stratified vectors containing individual unit operations were combined into one-dimensional square matrices [Rj]s. The [Rj]s meet the matrix representation of a group (ring) as a K-algebra. Using the same-sized matrix of stratified vectors, we can also express changes in the plural set of [Rj]s. The method is demonstrated on simple examples. Despite the incompleteness of our model, the group matrix representation of stratified vectors offers a formal mathematical approach to clinical medicine, aligning it with other branches of natural science.

Evaluation of a cognitive behavioural self-help manual for reducing depression: a randomized controlled trial.

The prevalence of depression is increasing in Thailand. We used a randomized controlled trial to examine the effectiveness of a self-help programme in reducing depression in people with depression in Chiang Mai Province in Thailand. Fifty-six individuals diagnosed with moderate depression participated. They were assigned randomly to an intervention (n= 27) or control (n= 29) group. The intervention group were given a self-help manual along with standard care and treatment, while the control group continued to receive standard care and treatment. Both groups were also given a short weekly telephone call. The findings showed statistically significant differences between the groups, and within the intervention group, in their depression levels. Between baseline and post-test, a sharp decrease in depression was evident in the intervention group, whereas the level of depression increased in the control group. Between post-test and follow-up, a decrease was apparent in depression in both groups. However, the intervention group showed a much lower level of depression than the control group. The results support the use of bibliotherapy as an adjunct to mental health nurses' and other professionals' work in caring for people with moderate depression in the community. http://www.ANZCTR.org.au/ACTRN12611000905965.aspx. © 2012 Blackwell Publishing.

When the neuroanesthesia working group of the Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor surveyed Spanish anesthesiologists to learn the degree of their involvement in the diagnosis and treatment of spontaneous subarachnoid hemorrhage, a surprising finding was that anesthetists did not participate in endovascular repair of intracranial aneurysms when the procedure was carried out in an interventional radiology department. These interventions, which are considered minimally invasive and are performed outside the operating room, are not risk-free. Based on the survey results and a systematic review of the literature, the working group has provided practice guidelines for the perioperative management of anesthesia for endovascular repair of ruptured cerebral aneurysms. In our opinion, the diversity of practice in the hospitals surveyed calls for the application of practice guidelines based on consensus if we are to reduce variability in clinical and anesthetic approaches as well as lower the rates of morbidity and mortality and shorten the hospital stay of patients undergoing exclusion of an aneurysm.

GPS net­work operations for the International GPS Geodynamics Service

1993-01-01

As GPS technology comes of age in the 1990’s, it is evident that an internationally sponsored GPS tracking system is called for to provide consistent, timely ground tracking data and data products to the geophysical community. The planning group for the International GPS Geodynamics Service (IGS), sponsored by the International Association of Geodesy (IAG), is addressing all elements of the end-to-end tracking system, ranging from data collection to data analysis and distribution of products (Mueller, 1992). Part of the planning process is to formulate how these various elements work together to create the common infrastructure needed to support a wide variety of GPS investigations. A key element for any permanent satellite tracking system is certainly the acquisition segment; the reliability and robustness of the ground network operations directly determine the fates and limitations of final products. The IGS planning group therefore included a committee tasked to develop and establish standards governing data acquisition and site-specific characteristics deemed necessary to ensure the collection of a high quality, continuous data set.

Culture Embrained: Going Beyond the Nature-Nurture Dichotomy.

PubMed

Kitayama, Shinobu; Salvador, Cristina E

2017-09-01

Over the past three decades, the cultural psychology literature has established that there is systematic cultural variation in the nature of agency in the domains of cognition, emotion, and motivation. This literature adopted both self-report and performance-based (or behavioral) indicators of these processes, which set the stage for a more recent systematic exploration of cultural influences at the neural and biological level. Moreover, previous work has largely focused on East-West differences, thereby calling for a systematic exploration of other ethnic groups. To address these issues, this article reviews recent work in cultural neuroscience, while paying close attention to Latino Americans-the single most rapidly growing minority group in the United States. We focus on research that has employed neural measures and show that culture has systematic influences on the brain. We also point out that, unlike more traditional self-report or performance-based measures, neural indicators of culture are reliably linked to theoretically relevant individual difference variables such as self-construal and acculturation. Cultural neuroscience offers the framework to go beyond the dichotomy between nature and nurture and to explore how they may dynamically interact.

[We are a band: An anthropological vision of the medical community].

In this paper we try to explain, using an anthropological point of view, how the medical community behaves like a tribe like those who inhabit the Amazon forests or the African Savanna. The Family as fundamental unit of a band of hunter-gatherers also defines the Primary Care Centre and the professionals who work there, as an egalitarian group in which every member works for the good of the tribe. The leaders of the tribe, also called "Health Centre Managers", are also comparable to the "big men" of Polynesia or the aborigines, who leads hunting parties. Even the clashes between physicians about the responsibilities as regards patients have been described throughout history in the anthropological literature, and they repeat the patterns of the segmental groups. We finish by concluding that this vision of warring tribes has to be overcome in order to advance towards the improvement of our community's health.
