The three constructs of work-family conflict, emotional exhaustion and performance-based self-esteem are all related to tremendous negative consequences for the individual, the organization as well as for society. Even though there are studies that connect two of those constructs, the prospective relations between all three of them have not been studied yet. We explored the prospective relations between the three constructs in a large Swedish data set representative of the Swedish workforce. Gender differences in the relations were investigated. Longitudinal data with a 2-year time lag were gathered from 3,387 working men and women who responded to the 2006 and 2008 waves of the Swedish Longitudinal Occupational Survey of Health. Four different cross-lagged models were analysed. In the best fitting model, higher levels of work-family conflict at time 1 were associated with an increased level of performance-based self-esteem at time 2, but not with emotional exhaustion, after controlling for having children, gender, education and age. Also, relationships between emotional exhaustion at time 1 and work-family conflict and performance-based self-esteem at time 2 could be established. Furthermore, relationships between performance-based self-esteem time 1 and work-family conflict and emotional exhaustion time 2 were found. Multiple-group analysis did not show any differences in the relations of the tested constructs over time for either men or women. We conclude that the three constructs are interrelated and best understood through a reciprocal model. No differences were found between men and women.

Public sector mental health care providers are at high risk for burnout and emotional exhaustion which negatively affect job performance and client satisfaction with services. Few studies have examined ways to reduce these associations, but transformational leadership may have a positive effect. We examine the relationships between transformational leadership, emotional exhaustion, and turnover intention in a sample of 388 community mental health providers. Emotional exhaustion was positively related to turnover intention, and transformational leadership was negatively related to both emotional exhaustion and turnover intention. Transformational leadership moderated the relationship between emotional exhaustion and turnover intention, indicating that having a transformational leader may buffer the effects of providers' emotional exhaustion on turnover intention. Investing in transformational leadership development for supervisors could reduce emotional exhaustion and turnover among public sector mental health providers.

Pain and emotional exhaustion are prevalent conditions with consequences for sickness absence. Although they often co-occur, their combined associations with sickness absence are poorly understood. This study aimed to examine the separate and combined associations of pain and emotional exhaustion with subsequent sickness absence. The data were derived from a cross-sectional questionnaire survey sent to 40 to 60-year-old employees of the City of Helsinki in 2000 to 2002 (n = 6457) linked with the City of Helsinki personnel register information on sickness absence (3 years on from the survey). Self-certified (1-3 days) and medically certified sickness absence spells (4-14 days, more than 14 days) were used as outcomes. Acute and chronic pain and emotional exhaustion were measured in a questionnaire survey. For the purposes of this study, sickness absence and pain variables were merged to form a new variable with 6 mutually exclusive categories. The main statistical method was negative binomial regression analysis. The synergy index was used to estimate the interaction. Among women, acute and chronic pain with and without emotional exhaustion predicted sickness absence, particularly absence lasting for more than 2 weeks, whereas emotional exhaustion alone did not. The associations persisted when further adjusted for socioeconomic and sociodemographic factors, health-related behaviors, and somatic and mental health. A synergistic interaction effect was found for co-occurring pain and emotional exhaustion on medically certified sickness absence. The results for men were mainly similar, but less stable. In order to tackle sickness absence, special attention should be paid to the prevention and treatment of employees with co-occurring pain and emotional exhaustion.

Full Text Available The purpose of this study was to determinate the job satisfaction and emotional exhaustion of tour guides in rural areas and to show how these two concepts are related to each other. A total of 102 tour guides, who lead tours or have experience in leading tours in rural areas took part in the questionnaire and the results were given and processed in SPSS version 17. Tour guides have a great importance in interpretation of rural areas as well as a significant role in presenting local customs and products in rural tourism. Exploring their satisfaction but also emotional exhaustion is of paramount importance for maintaining their excellence in interpretation of these areas. The results indicate that job satisfaction is still not on satisfying level, while emotional exhaustion is under acceptable limits. The results also showed that there is a negative connection between these two concepts. The obtained data should be beneficial not only to tour-operators but also to other tourism-related companies dealing with FDA (Front Desk Activities and employees in rural tourism: the data about job satisfaction and emotional exhaustion of tour guides can be used in developing management and work motivation strategies. The profound insight in job satisfaction and emotional exhaustion is important in order to achieve business excellence of tour guides in rural areas.

Full Text Available Abstract Background This study examined the associations of job control, organizational justice and bullying at the workplace with emotional exhaustion. This was done by adjusting firstly for age and occupational class, secondly physical work factors, thirdly mutually adjusting for the three psychosocial factors and fourthly adjusting for all studied variables simultaneously. Data were derived from the Helsinki Health Study baseline surveys conducted in 2001 and 2002, including 40-60-year-old employees of the City of Helsinki (n = 5819, response rate 66%. Exhaustion was measured with a six-item subscale from Maslach Burnout Inventory (MBI. Psychosocial factors included Karasek's job control, organizational justice and bullying at the workplace. Logistic regression analysis was used. Results Among women 23% and among men 20% reported symptoms of emotional exhaustion. Among women all psychosocial factors were associated with exhaustion when adjusted for age and occupational class as confounders. When physical work factors were additionally adjusted for, the associations slightly attenuated but remained. When psychosocial work factors were simultaneously adjusted for each other, their associations with exhaustion attenuated but remained. Among men all psychosocial factors were associated with exhaustion when adjusted for confounders only. When adjusted for physical work factors the associations slightly attenuated. When psychosocial factors were simultaneously adjusted for each other, associations of organizational justice and bullying with exhaustion attenuated but remained whereas job control lost its association. Conclusions Identifying risk factors for emotional exhaustion is vital for preventing subsequent processes leading to burnout. Psychosocial factors are likely to contribute to exhaustion among female as well as male employees. Thus management and occupational health care should devote more attention to the psychosocial work environment

Effectively managing patient safety and clinicians' emotional exhaustion are important goals of healthcare organizations. Previous cross-sectional studies showed that teamwork is associated with both. However, causal relationships between all three constructs have not yet been investigated. Moreover, the role of different dimensions of teamwork in relation to emotional exhaustion and patient safety is unclear. The current study focused on the long-term development of teamwork, emotional exhaustion, and patient safety in interprofessional intensive care teams by exploring causal relationships between these constructs. A secondary objective was to disentangle the effects of interpersonal and cognitive-behavioral teamwork. We employed a longitudinal study design. Participants were 2100 nurses and physicians working in 55 intensive care units. They answered an online questionnaire on interpersonal and cognitive-behavioral aspects of teamwork, emotional exhaustion, and patient safety at three time points with a 3-month lag. Data were analyzed with cross-lagged structural equation modeling. We controlled for professional role. Analyses showed that emotional exhaustion had a lagged effect on interpersonal teamwork. Furthermore, interpersonal and cognitive-behavioral teamwork mutually influenced each other. Finally, cognitive-behavioral teamwork predicted clinician-rated patient safety. The current study shows that the interrelations between teamwork, clinician burnout, and clinician-rated patient safety unfold over time. Interpersonal and cognitive-behavioral teamwork play specific roles in a process leading from clinician emotional exhaustion to decreased clinician-rated patient safety. Emotionally exhausted clinicians are less able to engage in positive interpersonal teamwork, which might set in motion a vicious cycle: negative interpersonal team interactions negatively affect cognitive-behavioral teamwork and vice versa. Ultimately, ineffective cognitive

Counselor emotional exhaustion has negative implications for treatment organizations as well as the health of counselors. Quality clinical supervision is protective against emotional exhaustion, but research on the mediating mechanisms between supervision and exhaustion is limited. Drawing upon data from 934 counselors affiliated with treatment programs in the National Institute on Drug Abuse's Clinical Trials Network (CTN), this study examined commitment to the treatment organization and commitment to the counseling occupation as potential mediators of the relationship between quality clinical supervision and emotional exhaustion. The final ordinary least squares (OLS) regression model, which accounted for the nesting of counselors within treatment organizations, indicated that these two types of commitment were plausible mediators of the association between clinical supervision and exhaustion. Higher quality clinical supervision was strongly correlated with commitment to the treatment organization as well as commitment to the occupation of SUD counseling. These findings suggest that quality clinical supervision has the potential to yield important benefits for counselor well-being by strengthening ties to both their employing organization as well the larger treatment field, but longitudinal research is needed to establish these causal relationships.

The importance of work-home interface stress can vary throughout a medical career and between genders. We studied changes in work-home interface stress over 5 yr, and their prediction of emotional exhaustion (main dimension of burn-out), controlled for other variables. A nationwide doctor cohort (NORDOC; n=293) completed questionnaires at 10 and 15 yr after graduation. Changes over the period were examined and predictors of emotional exhaustion analyzed using linear regression. Levels of work-home interface stress declined, whereas emotional exhaustion stayed on the same level. Lack of reduction in work-home interface stress was an independent predictor of emotional exhaustion in year 15 (β=-0.21, p=0.001). Additional independent predictors were reduction in support from colleagues (β=0.11, p=0.04) and emotional exhaustion at baseline (β=0.62, pwork-home interface stress among women, and reduction of collegial support and lack of reduction in working hours among men. Thus, change in work-home interface stress is a key independent predictor of emotional exhaustion among doctors 15 yr after graduation. Some gender differences in predictors of emotional exhaustion were found.

Preventing work injuries requires a clear understanding of how they occur, how they are recorded, and the accuracy of injury surveillance. Our innovation was to examine how psychosocial safety climate (PSC) influences the development of reported and unreported physical and psychological workplace injuries beyond (physical) safety climate, via the erosion of psychological health (emotional exhaustion). Self-report data (T2, 2013) from 214 hospital employees (18 teams) were linked at the team level to the hospital workplace injury register (T1, 2012; T2, 2013; and T3, 2014). Concordance between survey-reported and registered injury rates was low (36%), indicating that many injuries go unreported. Safety climate was the strongest predictor of T2 registered injury rates (controlling for T1); PSC and emotional exhaustion also played a role. Emotional exhaustion was the strongest predictor of survey-reported total injuries and underreporting. Multilevel analysis showed that low PSC, emanating from senior managers and transmitted through teams, was the origin of psychological health erosion (i.e., low emotional exhaustion), which culminated in greater self-reported work injuries and injury underreporting (both physical and psychological). These results underscore the need to consider, in theory and practice, a dual physical-psychosocial safety explanation of injury events and a psychosocial explanation of injury underreporting.

To examine the relationships among employees' emotional exhaustion, positive and negative work-home interaction, and perceived work-life balance culture in companies. Data for this study were collected through online surveys of employees from companies in the micro- and nanotechnology sectors (N = 509). A structural equation modeling analysis was performed. A company culture perceived by employees as supportive of their work-life balance was found to have both a direct negative effect on emotional exhaustion and an indirect negative effect meditated by negative work-home interaction. In addition, whereas negative work-home interaction associated positively with emotional exhaustion, positive work-home interaction had no significant effect. The direct and indirect relationship between work-life balance culture and emotional exhaustion has practical implications for health promotion in companies.

Although a growing body of research links leadership behavior to follower health, comparatively little is known about the health effects of being in the lead. This longitudinal study of 315 team members and 67 leaders examined the crossover of emotional exhaustion and work engagement from followers to leaders. Leader emotional self-efficacy was tested as a moderator in the crossover process. Multiple regression analyses revealed that followers' work engagement was positively related to leaders' work engagement eight months later, controlling for followers' tenure with the leader, leader gender, autonomy, workload, and work engagement at Time 1. Leaders' emotional self-efficacy did not moderate the crossover of work engagement. Followers' emotional exhaustion was not directly related to leaders' emotional exhaustion over time. We did find a significant interaction effect for follower emotional exhaustion and leader emotional self-efficacy. This study is the first to show that crossover of emotional exhaustion and work engagement can unfold over time from team members to leaders. Main theoretical implications lie in the finding that-in line with job demands-resources theory-followers' psychological states can pose a demand or resource for leaders, and influence their well-being. For practitioners, our results offer valuable insights regarding the design of organizational health interventions as well as leadership development measures.

To conduct an investigation similar to a landmark study that investigated the association between nurse-to-patient ratio and patient mortality, failure-to-rescue, emotional exhaustion and job satisfaction of nurses. Cross-sectional analysis of 2709 general, orthopedic, and vascular surgery patients, and 140 staff nurses (42% response rate) caring for these patients in a large Midwestern institution. The main outcome measures were mortality, failure-to-rescue, emotional exhaustion, and job dissatisfaction. Staffing was not a significant predictor of mortality or failure-to-rescue, nor did clinical specialty predict emotional exhaustion or job dissatisfaction. Although these findings reinforce adequate staffing ratios at this institution, programs that support nurses in their daily practice and positively impact job satisfaction need to be explored. The Nursing Research Council not only has heightened awareness of how staffing ratios affect patient and nurse outcomes, but also a broader understanding of how the research process can be used to effectively shape nurse's practice and work environments.

Emotional dissonance, i.e., a discrepancy between required and felt emotions, has been established as a predictor of sickness absence in studies, but little is known about mechanisms that can explain this association. In order to prevent and reduce the impact of emotional dissonance on sickness absence, there is a need for greater attention to variables explaining when and how emotional dissonance is related to sickness absence. The overarching aim of this study was to examine whether emotional dissonance has an indirect association with sickness absence through exhaustion. In addition, we examined whether human resource primacy (HRP), which is the employer's degree of concern for human resources, moderates this indirect effect. A sample of 7758 employees, all working with customers and clients, were recruited from 96 Norwegian organizations. Emotional dissonance, exhaustion, and HRP were measured through surveys and then linked to registry data on medically certified sickness absence for the year following the survey assessment. Results showed that exhaustion is a mediator for the relationship between emotional dissonance and sickness absence. Furthermore, higher levels of HRP were found to reduce the positive association between emotional dissonance and exhaustion, and the indirect effect of emotional dissonance on sickness absence through exhaustion is found to be weaker when HRP is high. By testing this moderated mediation model, the current study contributes to the literature on emotion work by clarifying mechanisms that are crucial for the development of targeted interventions that aim to reduce and prevent sickness absence in client-driven work environments.

The aim of the present study was to explore if an acute stress will increase auditory sensitivity (hyperacusis in individuals with high levels of emotional exhaustion (EE. METHODS: Hyperacusis was assessed using uncomfortable loudness levels (ULL in 348 individuals (140 men; 208 women; age 23-71 years. Multivariate analyses (ordered logistic regression, were used to calculate odds ratios, including interacting or confounding effects of age, gender, ear wax and hearing loss (PTA. Two-way ANCOVAs were used to assess possible differences in mean ULLs between EE groups pre- and post-acute stress task (a combination of cold pressor, emotional Stroop and Social stress/video recording. RESULTS: There were no baseline differences in mean ULLs between the three EE groups (one-way ANOVA. However, after the acute stress exposure there were significant differences in ULL means between the EE-groups in women. Post-hoc analyses showed that the differences in mean ULLs were between those with high vs. low EE (range 5.5-6.5 dB. Similar results were found for frequencies 0.5 and 1 kHz. The results demonstrate that women with high EE-levels display hyperacusis after an acute stress task. The odds of having hyperacusis were 2.5 (2 kHz, right ear; left ns and 2.2 (4 kHz, right ear; left ns times higher among those with high EE compared to those with low levels. All these results are adjusted for age, hearing loss and ear wax. CONCLUSION: Women with high levels of emotional exhaustion become more sensitive to sound after an acute stress task. This novel finding highlights the importance of including emotional exhaustion in the diagnosis and treatment of hearing problems.

Burnout is a major problem for nursing. There is a strong relationship between work stress and emotional exhaustion. Although studies report a negative correlation between the internal locus of control and emotional exhaustion and work stress, the number of studies available on the subject is limited. This study intends to examine the extent to which the relationship between work stress and emotional exhaustion is mediated by nurses' internal locus of control. The study adopted a cross-sectional survey design. The data were analyzed using structural equation modeling techniques. The study sample consisted of 347 nurses who worked in a university hospital in Izmir, Turkey and who agreed to participate in the study. The Work-Related Strain Inventory was used to evaluate the nurses' work stress level, Maslach Burnout Inventory was used to evaluate their emotional exhaustion levels, and the Locus of Control Scale was used to evaluate the internal locus of control. The variables of the study were based on the Neuman Systems Model. Work stress was positively related to internal locus of control (β3 = .21, p 0.1). Internal locus of control was negatively related to emotional exhaustion (β = -.14, p Work stress is directly (β = .87, p Work stress is directly (β = .87, p work stress was mediated, the impact of internal locus of control was limited. It is recommended that different variables be included in future studies so that they can mediate the relationship between work stress and emotional exhaustion.

Mechanisms linking authentic leadership to emotional exhaustion: The role of procedural justice and emotional demands in a moderated mediation approach.

Kampa, Judith; Rigotti, Thomas; Otto, Kathleen

2017-04-07

In order to gain more knowledge on how the positive leadership concept of authentic leadership impacts follower strain, this study tries to uncover procedural justice as an underlying mechanism. In contrast to previous work, we exclusively base our theoretical model on justice theories. Specifically, we hypothesize that authentic leadership negatively predicts emotional exhaustion through perceptions of procedural justice. We assume that this indirect effect is conditional on followers' amount of emotional demands, and that the procedural justice-emotional exhaustion relationship is stronger when emotional demands are high. This finally results in a stronger exhaustion-reducing effect of authentic leadership. The proposed moderated mediation model was tested in a sample of N=628 employees nested in 168 teams using lagged data from three waves. Results provide support for all hypotheses. Authentic leadership is critical to employees' well-being as it contributes to an elevated perception of positive work conditions (procedural justice), especially in contexts with high emotional demands. Limitations and practical implications on leadership development are discussed.

[Somatic and mental morbidity of young female physicians. Does emotional exhaustion constitute the missing link?].

The high prevalence of morbidity among female physicians in Hungary is well documented, however, little is known about the prevalence of that in certain age groups. To assess the prevalence of somatic and psychiatric morbidity in two age cohorts (Cohort 1: age 24-43 and Cohort 2: age 44-76) of female physicians and to explore the relationship between morbidity and potential risk factors including work-related stressors. Representative, cross-sectional, quantitative survey among representative samples of female physicians (N = 408). Physicians in Cohort 1 reported more frequent night shift rotation, less leisure time, and fewer days off compared to physicians in Cohort 2. Physicians in Cohort 1 were less satisfied with their work, workplace, reported less support from their colleagues, and received lower salary compared to physicians in Cohort 2. Physicians in Cohort 1 scored significantly higher on the emotional exhaustion and the personal accomplishment scales MBI as compared to Cohort 2 physicians. In Cohort 1 emotional exhaustion and personal accomplishment were associated with high depression scores and frequent suicidal ideation. The role of emotional exhaustion is decisive of young physicians' well-being. Future research should focus on understanding the psycho-social, individual, organizational, and societal correlates of the high prevalence of morbidity among young female physicians in Hungary.

To explore the relationship between nurse outcomes (dissatisfaction and emotional exhaustion) and nurse workload, nurse characteristics and hospital variables. Concern about the impact of restructuring of nurse staffing, and reports of nurse shortages, on nurse and patient outcomes led to the research being reported on in this article. A questionnaire survey of registered nurses in Scotland and England. A questionnaire survey of the hospitals in which these nurses worked. Respondents in the two countries were similar in terms of demographic, work and employment characteristics. Significant relationships were found using the combined English and Scottish data between nurse patient ratios and (1) emotional exhaustion and (2) dissatisfaction with current job reported by nurses. Increasing numbers of patients to nurses was associated with increasing risk of emotional exhaustion and dissatisfaction with current job.

By using a two-wave panel design, the present study aimed to study causal, reversed, and reciprocal relations among work-role conflict, work-family conflict, and emotional exhaustion. The Conservation of Resources theory was applied as a theoretical framework. The study was conducted in a large Norwegian oil and gas company (n = 1703). The results demonstrated positive cross-lagged effects of work-role conflict and work-family conflict on emotional exhaustion. In addition, emotional exhaustion predicted work-family conflict over time, and work-family conflict predicted work-role conflict over time, indicating the presence of reciprocal effects. The current study adds new knowledge to the positioning of work-family conflict in relation to perceived conflict in the workplace and emotional exhaustion. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

In order to gain more knowledge on how the positive leadership concept of authentic leadership impacts follower strain, this study tries to uncover procedural justice as an underlying mechanism. In contrast to previous work, we exclusively base our theoretical model on justice theories. Specifically, we hypothesize that authentic leadership negatively predicts emotional exhaustion through perceptions of procedural justice. We assume that this indirect effect is conditional on followers’ amount of emotional demands, and that the procedural justice-emotional exhaustion relationship is stronger when emotional demands are high. This finally results in a stronger exhaustion-reducing effect of authentic leadership. The proposed moderated mediation model was tested in a sample of N=628 employees nested in 168 teams using lagged data from three waves. Results provide support for all hypotheses. Authentic leadership is critical to employees’ well-being as it contributes to an elevated perception of positive work conditions (procedural justice), especially in contexts with high emotional demands. Limitations and practical implications on leadership development are discussed. PMID:27818452

Addiction to social media has now become a problem that societies are concerned with. The aim of the present study is to investigate the impacts that social media addiction has on mindfulness and choice of coping strategy, as well as to explore the consequences on emotional exhaustion. The survey data were collected from 211 employees in 13 enterprises in Thailand. Results from partial least square structural equation modelling revealed that people who are highly addicted to social media tended to have lower mindfulness and tended to use emotion-focused coping to deal with stress. Lack of mindfulness and the decision to use emotion-coping strategy are also subsequently associated with higher emotional exhaustion. Copyright © 2015 John Wiley & Sons, Ltd.

Emotional exhaustion is an important component of burnout. Burnout is common among doctors. It affects the physical and mental health of doctors, their performance and the quality of care they provide. This study aimed to investigate the level and factors associated with emotional exhaustion among doctors in pediatric practice in Malaysia. A self-administered questionnaire was used in this multicenter cross-sectional study. It included questions on the socio-demographics, work characteristics, Emotional Exhaustion, Perceived Stress Scale and sources of job stress. Descriptive, univariate and multivariate analysis were conducted using the SPSS software. A total of 197 doctors working in the Pediatric department in eight hospitals returned complete questionnaire. High and moderate emotional exhaustion was reported by 25.4% and 24.4% doctors, respectively. In bivariate analysis, 29 out of the 38 items of sources of stress showed significant association with emotional exhaustion (p appreciation from supervisors, lack of incentives and promotions, time pressures and deadlines to meet, and setting unrealistic goals of having them imposed on oneself (p workplace but not with socio-demographic factors.

The aim of the study was to examine the associations among work-family conflict (WFC), emotional exhaustion, musculoskeletal (MS) pain, and gastrointestinal problems on a sample of business travelers (n = 2,093). An additional aim was to examine differences in the mentioned relationships among three traveler groups: commuters, national travelers, and international travelers. The study was conducted in a large Norwegian oil and gas company, and the company's business travel database was utilized to examine business travel. Structural equation modeling (SEM) revealed significant relations between WFC and emotional exhaustion and between emotional exhaustion and health problems. Contrary to the expectations, no direct association was found between WFC and health problems. However, we found that emotional exhaustion mediated the relation between WFC and health outcomes. The results from multi-group analysis revealed that associations among WFC, emotional exhaustion, and health-outcomes showed a similar pattern for commuters, national travelers, and international travelers. However, the association between emotional exhaustion and MS pain proved to be significantly stronger for the commuter group compared to the national and international travel groups. Practical implications and the consequences of these findings for future research are discussed. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

This mixed methods study documents emotional exhaustion experiences among care team members during the development of an innovative team approach for caring for adults with serious illness. A mixed methods study design was employed to examine depleting work experiences that may produce emotional exhaustion, and energizing aspects of the work that may increase meaningfulness of work, thus reducing emotional exhaustion. The population studied included team members involved in care for adults with serious illness (n = 18). Team members were surveyed quarterly over an 18-month period using the Maslach Burnout Inventory (MBI). The MBI measures burnout, defined as the inability to continue work because of the interactional toll of the work. Analyses of MBI data show that although overall levels of burnout are low, 89% of team members reported moderate/high levels of emotional exhaustion during at least one survey period. In order to understand the kinds of work experiences that may produce or ameliorate emotional exhaustion, qualitative interviews were also conducted with team members at the end of the 18-month period. Major qualitative findings indicate that disputes within the team, environmental pressures, and standardisation of meaningful work leave team members feeling depleted. Having authentic relationships with patients, working as a team, believing in the care model, and practicing autonomy and creativity help team members to restore their emotional energy. Supports for team members' well-being are critical for continued innovation. We conclude with recommendations for improving team members' well-being.

Counterproductive work behaviours in response to emotional exhaustion: a moderated mediational approach.

Bolton, LaMarcus R; Harvey, Richard D; Grawitch, Matthew J; Barber, Larissa K

2012-08-01

Drawing from the conservation of resources framework and self-control principles, we proposed a moderated mediational model through which emotional exhaustion may be linked to counterproductive work behaviours (CWBs). Analyses conducted with 175 Midwestern government workers revealed that both depersonalization (i.e. detachment from one's work, customers or co-workers) and organizational disidentification (i.e. cognitive opposition to an organization) were viable predictors of deviancy. Further, depersonalization and disidentification mediated the relationship between emotional exhaustion and CWBs, although disidentification drove these findings. Lastly, trait self-control moderated most variations of this relationship, in that this mediational model only applied to individuals with low and moderate self-control but not high self-control. Consistent with the conservation of resources framework, this study suggests that in a state of depleted emotional resources, heightened depersonalization and disidentification together provide the necessary levels of psychological/emotional withdrawal and justification for CWBs to emerge.

We integrate deontological ethics (Folger, 1998, 2001; Kant, 1785/1948, 1797/1991) with conservation of resources theory (Hobfoll, 1989) to propose that an employee's repeated exposure to violations of moral principle can diminish the availability of resources to appropriately attend to other personal and work domains. In particular, we identify customer unethical behavior as a morally charged work demand that leads to a depletion of resources as captured by employee emotional exhaustion. In turn, emotionally exhausted employees experience higher levels of work-family conflict, relationship conflict with coworkers, and job neglect. Employee emotional exhaustion serves as the mediator between customer unethical behavior and such outcomes. To provide further evidence of a deontological effect, we demonstrate the unique effect of customer unethical behavior onto emotional exhaustion beyond perceptions of personal mistreatment and trait negative affectivity. In Study 1, we found support for our theoretical model using multisource field data from customer-service professionals across a variety of industries. In Study 2, we also found support for our theoretical model using multisource, longitudinal field data from service employees in a large government organization. Theoretical and practical implications are discussed. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

Hematologists and oncologists in private practice play a central role in the care provided for cancer patients. The present study analyzes stress and relaxation aspects in the work of hematologists and oncologists in private practice in Germany in relation to emotional exhaustion, as a core dimension of burnout syndrome. The study focuses on the opportunities for internal recovery using breaks and time out during the working day, the frequency of working on weekends and on vacation, and the physician's work-home and home-work conflict. Postulated associations between the constructs were analyzed using a structural equation model. If work leads to conflicts in private life (work-home conflict), it is associated with greater emotional exhaustion. Working frequently at the weekend is associated with greater work-home conflict and indirectly with greater emotional exhaustion. By contrast, the availability of opportunities to relax and recover during the working day is associated with less work-home conflict and indirectly with less emotional exhaustion. These results underline the importance of internal recovery opportunities during the working day and a successful interplay between working and private life for the health of outpatient hematologists and oncologists.

Many people working in human services in Western countries suffer from burnout, characterized by emotional exhaustion, depersonalization, and decreased personal performance. Prevention of emotional exhaustion (the first phase of burnout) constitutes a great challenge because emotional exhaustion may cause increasing turnover rates in staff and lead to a lesser quality of care. Prevention of emotional exhaustion requires knowledge of its predictors. The aim of this study was to investigate the associations between emotional exhaustion, social capital, workload, and latitude in decision-making among German professionals working in the care of persons with intellectual and physical disabilities. The study was based on a survey in a sheltered workshop and 5 homes for disabled persons with 175 professionals. Burnout was measured with the German version of the Maslach Burnout Inventory-General Survey (MBI-GS). A multivariate logistic regression analysis was computed. Logistic regression identified the following three significant predictors of emotional exhaustion in the sample: workload (OR, 4.192; CI, 2.136-8.227), latitude in decision-making (OR, 0.306; CI, 0.115-0.811), and male gender (OR, 4.123; CI, 1.796-9.462). Nagelkerke's Pseudo-R(2) was 0.344. The results of this study demonstrate that specific factors in work organization are associated with emotional exhaustion. Taking into account sociodemographic changes and the upcoming challenges for human services professionals, the results underline the importance of considering aspects of organization at the workplace to prevent burnout. Specific circumstances of male employees must be considered. Copyright 2009 Elsevier Ltd. All rights reserved.

Compared with the large literature on subordinate employees, there are few studies of emotional exhaustion and turnover intention for organizational leaders. There is little research that has extended the job demands-resources (JD-R) model of emotional exhaustion to leaders. In this study, the authors adapted the JD-R framework to analyze data collected from a sample of 410 leaders of addiction treatment organizations. The authors considered whether two job demands (performance demands and centralization) and two job resources (innovation in decision making and long-range strategic planning) were associated with emotional exhaustion and turnover intention. The authors also examined whether emotional exhaustion fully or partially mediated the associations between the job-related measures and turnover intention. The results supported the partially mediated model. Both job demands were positively associated with emotional exhaustion, and the association for long-range strategic planning was negative. Emotional exhaustion was positively associated with turnover intention. Centralization and innovation in decision making were also directly associated with turnover intention. Future research should continue to examine this theoretical framework among leaders of other types of organizations using more refined measures of demands and resources.

The purpose of the present research is to present a model pertaining to the mediating roles of rumination and recovery experiences in the relationship between a harmonious and an obsessive passion (Vallerand et al., 2003) for work and workers' emotional exhaustion. Two populations were measured in the present research: namely elite coaches and nurses. Study 1's model posits that obsessive passion positively predicts rumination about one's work when being physically away from work, while harmonious passion negatively predicts ruminative thoughts. In turn, rumination is expected to positively contribute to emotional exhaustion. The results of Study 1 were replicated in Study 2. In addition, in the model of Study 2, obsessive passion was expected to undermine recovery experiences, while harmonious passion was expected to predict recovery experiences. In turn, recovery experiences were expected to protect workers from emotional exhaustion. Results of both studies provided support for the proposed model. The present findings demonstrate that passion for work may lead to some adaptive and maladaptive psychological processes depending on the type of passion that is prevalent. © 2012 The Authors.

Fairness in the workplace attenuates a host of negative individual and organizational outcomes. However, research on the psychology of aging challenges the assumption that fairness operates similarly across different age groups. The current research explored how older workers, vis-à-vis younger workers, react to perceptions of fairness. Integrating socioemotional selectivity theory and the multiple needs theory of organizational justice, we generated novel predictions regarding the relations between perceptions of workplace justice, emotional exhaustion, and employee deviance. Specifically, we hypothesized and found that employee age moderates the negative relation between justice facets and deviance (Study 1) and emotional exhaustion (Study 2). We also found that emotional exhaustion mediates the differential effects of justice on deviance, and that this relation depends on employee age (Study 2). Relative to younger workers, older workers are more sensitive to informational and interpersonal justice; in contrast, relative to older workers, younger workers are more sensitive to distributive and procedural justice. The research supports and extends existing theory on organizational justice and on the psychology of aging. Moreover, it highlights the importance of considering employee age as a focal variable of interest in the study of justice processes, and in organizational research more generally.

Aims: To investigate the role of clinician burnout, demographic, and organizational characteristics in predicting subjective and objective indicators of patient safety. Background: Maintaining clinician health and ensuring safe patient care are important goals for hospitals. While these goals are not independent from each other, the interplay between clinician psychological health, demographic and organizational variables, and objective patient safety indicators is poorly understood. The present study addresses this gap. Method: Participants were 1425 physicians and nurses working in intensive care. Regression analysis (multilevel) was used to investigate the effect of burnout as an indicator of psychological health, demographic (e.g., professional role and experience) and organizational (e.g., workload, predictability) characteristics on standardized mortality ratios, length of stay and clinician-rated patient safety. Results: Clinician-rated patient safety was associated with burnout, trainee status, and professional role. Mortality was predicted by emotional exhaustion. Length of stay was predicted by workload. Contrary to our expectations, burnout did not predict length of stay, and workload and predictability did not predict standardized mortality ratios. Conclusion: At least in the short-term, clinicians seem to be able to maintain safety despite high workload and low predictability. Nevertheless, burnout poses a safety risk. Subjectively, burnt-out clinicians rated safety lower, and objectively, units with high emotional exhaustion had higher standardized mortality ratios. In summary, our results indicate that clinician psychological health and patient safety could be managed simultaneously. Further research needs to establish causal relationships between these variables and support to the development of managerial guidelines to ensure clinicians’ psychological health and patients’ safety.

Recognizing that bullying can occur in varying degrees of severity, the current study suggest the importance of individual traits in individual perceptions of being targets of bullying and ensuing emotional exhaustion. The present study extends the work environment hypothesis and trait activation theory by a joint investigation of the mediating role of (a) workplace bullying in linking perceived organization politics and perceived organization support with emotional exhaustion and (b) the moderating role of Type A behavioral pattern in influencing the mediation. Using a field sample of 262 employees working in different organizations of Pakistan, this study tested a moderated mediation model. Results were consistent with the hypothesized model, in that workplace bullying mediated the relationship of perceived organization politics and perceived organization support with emotional exhaustion. Type A behavior moderated the perceived politics-bullying, perceived support-bullying, and bullying-emotional exhaustion relationships. The mediation of bullying varied with levels of Type A behavior in these relationships.

Individual differences in emotional labor and subsequent vulnerability to burnout have been explored through the prism of Congruence Theory, which examines the congruence between personality traits and job requirements (Bono & Vey, 2007; Moskowitz & Coté, 1995). Drawing on theory and research dealing with the association between the need to belong and self-regulation (Baumeister, DeWall, Ciarocco & Twenge, 2005), this study examined the relationship between need to belong and service employees' surface acting and associated outcomes. In Study 1, participants (N = 54) were asked to write a response to an aggressive email from a hypothetical customer. The need to belong was positively related to display of positive emotions and negatively to display of negative emotions in the responses, but not related to felt anger, suggesting that it is associated with the inclination to engage in surface acting. In Study 2, a field study conducted with 170 service employee-customer dyads, surface acting mediated the positive relationship between fear of isolation and emotional exhaustion, and emotional exhaustion mediated the relationship between surface acting and customer satisfaction. These results suggested that service employees with a strong need to belong might have a heightened risk of burnout because of their inclination to engage in emotional labor.

The growing threat of terrorism has increased the importance of aviation security and the work of airport security officers (screeners). Nonetheless, airport security research has yet to focus on emotional exhaustion and job satisfaction as major determinants of screeners' job performance. The present study bridges this research gap by applying the job demands-resources (JD-R) model and using work-family conflict (WFC) as an intervening variable to study relationships between work characteristics (workload and supervisor support), emotional exhaustion, and job satisfaction in 1,127 screeners at a European airport. Results of structural equation modeling revealed that (a) supervisor support as a major job resource predicted job satisfaction among screeners; (b) workload as a major job demand predicted their emotional exhaustion; and (c) WFC proved to be a promising extension to the JD-R model that partially mediated the impact of supervisor support and workload on job satisfaction and emotional exhaustion. Theoretical and practical implications are discussed.

When studied separately, research shows that both teacher self-efficacy and teacher autonomy are associated with adaptive motivational and emotional outcomes. This study tested whether teacher self-efficacy and teacher autonomy are independently associated with engagement, job satisfaction, and emotional exhaustion. 2,569 Norwegian teachers in elementary school and middle school (719 men, 1,850 women; M age = 45.0 yr., SD = 11.5) were administered the Norwegian Teacher Self-Efficacy Scale, the Teacher Autonomy Scale, the Utrecht Work Engagement Scale, the Teacher Job Satisfaction Scale, and the Maslach Burnout Inventory. The analysis revealed that both teacher autonomy and self-efficacy were independent predictors of engagement, job satisfaction, and emotional exhaustion. This study suggests that autonomy or decision latitude works positively but through different processes for teachers with high and low mastery expectations.

Symptoms of Exhaustion Syndrome (ES) and Chronic Fatigue Syndrome (CFS) are overlapping and create difficulties of differential diagnosis. Empirical studies comparing ES and CFS are scarce. This study aims to investigate if there are any emotional differences between ES and CFS. This cross-sectional study compared self-reported alexithymia and observer-rated emotional awareness in patients with ES (n = 31), CFS (n = 38) and healthy controls (HC) (n = 30). Self-reported alexithymia was measured with the Toronto Alexithymia Scale-20 (TAS-20) and emotional awareness with an observer-rated performance test, the Level of Emotional Awareness Scale (LEAS). Additionally, depression and anxiety were scored by the Hospital Anxiety and Depression Scale (HADS). Results show that patients with ES expressed higher self-reported alexithymia in the TAS-20 compared to HC, but had similar emotional awareness capacity in the observer-rated performance test, the LEAS. Patients with CFS expressed more difficulties in identifying emotions compared to HCs, and performed significantly worse in the LEAS-total and spent more time completing the LEAS as compared to HC. Correlation and multiple regressions analyses revealed that depression and anxiety positively correlated with and explained part of the variances in alexithymia scores, while age and group explained the major part of the variance in LEAS. Findings of this study indicate that emotional status is different in patients with ES and CFS with respect to both self-reported alexithymia and observer-rated emotional awareness. Emotional parameters should be approached both in clinical investigation and psychotherapy for patients with ES and CFS. © 2016 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

Is Job Control a Double-Edged Sword? A Cross-Lagged Panel Study on the Interplay of Quantitative Workload, Emotional Dissonance, and Job Control on Emotional Exhaustion.

Previous meta-analytic findings have provided ambiguous evidence on job control as a buffering moderator of the adverse impact of job demands on psychological well-being. To disentangle these mixed findings, we examine the moderating effect of job control on the adverse effects of quantitative workload and emotional dissonance as distinct work-related demands on emotional exhaustion over time. Drawing on the job demands-control model, the limited strength model of self-control, and the matching principle we propose that job control can facilitate coping with work-related demands but at the same time may also require employees' self-control. Consequently, we argue that job control buffers the adverse effects of quantitative workload while it reinforces the adverse effects of emotional dissonance, which also necessitates self-control. We examine the proposed relations among employees from an energy supplying company ( N = 139) in a cross-lagged panel study with a six-month time lag. Our results demonstrate a mix of causal and reciprocal effects of job characteristics on emotional exhaustion over time. Furthermore, as suggested, our data provides evidence for contrasting moderating effects of job control.

Full Text Available Previous meta-analytic findings have provided ambiguous evidence on job control as a buffering moderator of the adverse impact of job demands on psychological well-being. To disentangle these mixed findings, we examine the moderating effect of job control on the adverse effects of quantitative workload and emotional dissonance as distinct work-related demands on emotional exhaustion over time. Drawing on the job demands-control model, the limited strength model of self-control, and the matching principle we propose that job control can facilitate coping with work-related demands but at the same time may also require employees’ self-control. Consequently, we argue that job control buffers the adverse effects of quantitative workload while it reinforces the adverse effects of emotional dissonance, which also necessitates self-control. We examine the proposed relations among employees from an energy supplying company (N = 139 in a cross-lagged panel study with a six-month time lag.

Emotional exhaustion (EE) is the core component in the study of teacher burnout, with significant impact on teachers' professional lives. Yet, its relation to teachers' emotional experiences and emotional labor (EL) during instruction remains unclear. Thirty-nine German secondary teachers were surveyed about their EE (trait), and via the experience sampling method on their momentary (state; N = 794) emotional experiences (enjoyment, anxiety, anger) and momentary EL (suppression, faking). Teachers reported that in 99 and 39% of all lessons, they experienced enjoyment and anger, respectively, whereas they experienced anxiety less frequently. Teachers reported suppressing or faking their emotions during roughly a third of all lessons. Furthermore, EE was reflected in teachers' decreased experiences of enjoyment and increased experiences of anger. On an intra-individual level, all three emotions predict EL, whereas on an inter-individual level, only anger evokes EL. Explained variances in EL (within: 39%, between: 67%) stress the relevance of emotions in teaching and within the context of teacher burnout. Beyond implying the importance of reducing anger, our findings suggest the potential of enjoyment lessening EL and thereby reducing teacher burnout.

Emotional exhaustion among healthcare workers is a widely investigated, well-recognized problem, the incidence of which has recently been linked to work environment factors, particularly work/family conflict. However, another environmental feature that may be equally influential, but that is more amenable to nurse manager action, remains less recognized: shift schedule flexibility. This study's main purposes were to assess variations in work schedule flexibility between Swiss acute care hospital units, and to investigate associations between psychosocial work environment (e.g. work schedule flexibility) and self-reported emotional exhaustion among registered nurses. This is a secondary analysis of data collected for the multi-center observational cross-sectional Match RN study, which included a national sample of 23 hospitals and 1833 registered nurses across Switzerland. Overall, self-reported work schedule flexibility among registered nurses was limited: 32% of participants reported little or no influence in planning their own shifts. Work schedule flexibility (β -0.11; CI -0.16; -0.06) and perceived nurse manager ability (β -0.30; CI -0.49; -0.10) were negatively related to self-reported emotional exhaustion. Work-family conflict (β 0.39; CI 0.33; 0.45) was positively correlated to emotional exhaustion. The study results indicate that managerial efforts to improve working environments, including special efforts to improve work schedule flexibility, might play an important role in promoting nurses' emotional health.

Chen, Erhu; Wang, Xuelin; Shang, Chengjia

Automotive engine exhaust gas after combustion of fuel, and the gas will be liquefied in the rear of automotive exhaust system. A lot of corrosive anions existing in the condensate make corrosion of the exhaust system materials. Therefore, once pitting perforation, automotive exhaust system will fail directly. In 1980s, automotive exhaust manifold was made of Si-Mo ductile iron, mufflers and the tail pipe were made of carbon steel or aluminized steel. But with higher emission standards carried out, the improvement of engine performance and the higher exhaust temperature as well as the needs of the automotive light-weighting, we need the higher corrosion resistance of the material for automotive exhaust systems to meet the requirements.

To investigate how psychosocial factors (such as job demands and work-family conflict) produce absenteeism in the workplace, using the health impairment process of the job demands-resources model. According to this model, job demands lead to burnout (often measured with the emotional exhaustion component), which in turn could lead to outcomes (such as absenteeism). Work-family conflict (WFC) was also studied, because of contradictory results collected in the existing literature on absenteeism in the workplace, regarding the role of WFC in causing absenteeism. Data were collected on 245 workers using both subjective (questionnaire on psychological risk factors and work-related health) and objective data (sickness leave frequency records). To test the hypothesis that job demands and WFC contribute to absenteeism in the workplace, a subsequent mediation analysis was used, which analysed both (a) the subsequent mediation of WFC and emotional exhaustion and (b) the separate roles played by the mediators proposed (WFC and emotional exhaustion). Job demands affect absenteeism through the subsequent mediation of WFC and emotional exhaustion. In addition, emotional exhaustion mediates the relationship between job demands and absenteeism, while WFC does not. In conclusion, subsequent mediation highlights the role of emotional exhaustion in causing absenteeism; in fact, when emotional exhaustion is included in the analysis, job demands are associated with higher levels of absenteeism. The results of this study suggest that without the concurrent contribution of emotional exhaustion, WFC does not influence absenteeism in the workplace. Our findings are useful for organizations that aim to reduce absenteeism.

"Service with a smile" is satisfying for the customer, but such display rules may be costly to the employee and the organization. Most previous research on such costs has used self-reported and cross-sectional designs. The authors use an experimental approach to test tenets of resource depletion theories; specifically, whether the self-regulation of emotions required by display rules depletes energy and attentional resources during a service encounter. Using a call center simulation with three "customer" interactions, the authors found that participants given positive display rules (e.g., be enthusiastic and hide frustration) reported more postsimulation exhaustion and made more errors on the order form compared to those with display autonomy. Customer hostility during one of the calls also increased exhaustion overall and the number of errors during that specific call, though proposed interactions with display rules were not supported. Surface-level emotion regulation, but not deep-level, was the mechanism for the energy depletion effect of display rules, while display rules had a direct effect on performance decrements. Theoretical and practical implications for display rules as part of job requirements are discussed. Copyright 2007 APA

2017-10-01

The aim of the study was to examine the relationship between role stress, emotional exhaustion, and a supportive coworker climate among health care workers, by adopting a multilevel perspective. Aggregated data of 738 health care workers nested within 67 teams of three Italian hospitals were collected. Multilevel regression analysis with a random intercept model was used. Hierarchical linear modeling showed that a lack of role clarity was significantly linked to emotional exhaustion at the individual level. At the unit level, the cross-level interaction revealed that a supportive coworker climate moderated the relationship between lack of role clarity and emotional exhaustion. This study supports previous results of single-level burnout studies, extending the existing literature with evidence on the multidimensional and cross-level interaction associations of a supportive coworker climate as a key aspect of job resources on burnout.

Taking a resource-based self-regulation perspective, this study examined afternoon emotional exhaustion as a mediator linking the within-person relations between morning work-family conflict and later employee displaced aggression in the work and family domains. In addition, it examined resource-related contextual factors as moderators of these relations. The theoretical model was tested using daily diary data from 125 employees. Data were collected at 4 time points during each workday for 3 consecutive weeks. Multilevel modeling analysis showed that morning family-to-work conflict was positively related to afternoon emotional exhaustion, which in turn predicted displaced aggression toward supervisors and coworkers in the afternoon and displaced aggression toward family members in the evening. In addition, morning workplace interpersonal conflict exacerbated the impact of morning work-to-family conflict on afternoon emotional exhaustion, whereas perceived managerial family support alleviated the impact of morning family-to-work conflict on afternoon emotional exhaustion. These findings indicate the importance of adopting a self-regulation perspective to understand work-family conflict at work and its consequences (i.e., displaced aggression) in both work and family domains.

A long research tradition has investigated the impact of stress on university students by assuming that individuals have a limited reservoir of resources, and that negative events and circumstances progressively drain resources thereby producing exhaustion. A recent research tradition, instead, has focused on the detrimental consequences of discrepant levels of implicit (ISE) and explicit (ESE) self-esteem on the development of stress-related symptoms. The present research attempted to merge the aforementioned approaches, with the aim of explaining significant predictors of stress. Within the framework of a Longitudinal Structural Equation Model, we followed a moderated-mediated approach. A sample of university students (N = 209; 66% females) completed a questionnaire battery including measures of ISE, ESE, perceptions of negative events, and emotional exhaustion. Participants were assessed once a week for eight consecutive weeks. ISE significantly moderated the relationship between ESE and negative events; in turn, the latter significantly predicted emotional exhaustion. Monte Carlo method for assessing mediation showed that negative events significantly mediated the relationship between incongruent self-esteem and emotional exhaustion. The detrimental role of incongruent self-esteem has been corroborated. Practical implications and suggestions for future research dealing with stress in a university setting were provided.

Full Text Available Purpose: Building on the Conservation of Resources theory, this paper examined the unique and interactive associations of negative and positive work-to-family spillover (NWFS and PWFS, respectively at the individual and organizational level with hotel managers’ wok exhaustion and satisfaction, beyond job demands and supervisors’ leadership style. Design/methodology/approach: Guided by the levels of analysis framework, we first tested the unique associations of NWFS and PWFS with emotional exhaustion and job satisfaction at the individual level (571 hotel managers, beyond job demands supervisors’ leadership style. Second, using multilevel modeling, we tested the climate effects of NWFS and PWFS on emotional exhaustion and job satisfaction aggregated at the organizational level (41 hotels. Third, we examined the role of the organizational climate of PWFS in the associations of individual-level NWFS with emotional exhaustion and job satisfaction. Findings: Beyond the effects of psychological job demands and supervisor’s transformational leadership, at the individual level, hotel managers who experienced higher NWFS than other managers reported more exhaustion and lower job satisfaction, whereas those with higher PWFS reported less exhaustion and higher satisfaction. At the organizational level, working in hotels where the average level of NWFS was higher than other hotels was associated with feeling more exhaustion of the individual members; working in hotels with higher PWFS was associated with feeling less exhaustion. The negative link between individual-level NWFS and job satisfaction was buffered when organization-level PWFS was higher, compared to when it was lower. Originality/value: This study moves beyond a focus on traditional job characteristics, toward considering individual and organizational experiences in the work-family interface as unique predictors of work exhaustion and satisfaction.

To investigate factors including adherence to "maternal affection" and stereotypical gender roles associated with emotional exhaustion among hospital nurses. In 2014, among 2,690 workers recruited for this study, 891 participated with written informed consent. Of these, we investigated 464 hospital nurses. Adherence to maternal affection and emotional exhaustion were measured using valid and reliable scales developed by Egami (2005, 12 items) and Kubo (1992, 5 items), respectively. Stereotypical gender role was measured by asking "how much do you agree with the idea that women should stay home and men should work?". Workfamily conflict was measured in terms of the discrepancy in priority in life (i.e., a work or a private life) between the participant's ideal and the real world. The majority of our participants were women (86%), aged 39 or younger (80%), and single (70%). About one-quarter had workfamily conflict (26%) and agreed with the stereotypical gender role (28%). The mean scores of emotional exhaustion and adherence to maternal affection were 17.2 (out of 25) and 30.8 (out of 48), respectively. A stepwise multivariable model showed that being a woman (p=0.028), being young (p=0.022), being single (p=0.007), and having workfamily conflict (pgender role were not significantly associated with emotional exhaustion. This study demonstrated that adherence to "maternal affection" and stereotypical gender roles were not associated with psychological burnout. Special attention should be paid to hospital nurses who are women, young, or single, or who have workfamily conflict.

Emotional Dissonance, Mental Health Complaints, and Sickness Absence Among Health- and Social Workers. The Moderating Role of Self-Efficacy

Indregard, Anne-Marthe R.; Knardahl, Stein; Nielsen, Morten B.

2018-01-01

Health- and social workers are frequently exposed to emotionally demanding work situations that require emotion regulation. Studies have demonstrated a direct relationship between emotion regulation and health complaints and sickness absence. In order to prevent health complaints and to reduce sickness absence among health- and social workers, there is need for greater attention to mechanisms explaining when and how emotionally demanding work situations are related to employee health and sickness absence. The overarching aim of this study was therefore to examine the moderating role of generalized self-efficacy on the association between emotional dissonance, employee health (mental distress and exhaustion), and registry based sickness absence. The sample consisted of 937 health- and social workers. Data on emotional dissonance, generalized self-efficacy, exhaustion, and mental distress was collected through questionnaires, whereas official registry data were used to assess sickness absence. A two-step hierarchical regression analysis showed that emotional dissonance was significantly associated with exhaustion, mental distress, and sickness absence, after adjusting for sex, age, and occupation. Interaction analyses with simple slope tests found that self-efficacy moderated the association between emotional dissonance and both exhaustion and mental distress, but not the association with sickness absence. This study shows that health- and social workers who frequently experience emotional dissonance report higher levels of exhaustion and mental distress, and have a higher risk of medically certified sickness absence. Further, health- and social workers with lower self-efficacy beliefs are apparently more sensitive to the degree of emotional dissonance and experienced higher levels of exhaustion and mental distress.

In service industry, employees'emotion displaying exerts influence on customers'satisfaction, their own per-formance and exhaustion.How an employee express his or her emotion is not only motivated by his own true emotion but also is directed by emotion display rules of the organization.Two kinds of emotional rules, which are expressing positive emotion and inhibiting negative emotion, give burden to ones'emotional sources and cause effect on ones'e-motional exhaustion.Therefore, we hypothesized that expressing emotional displaying rules have positive relation with exhaustion.Emotional labor has direct relation with exhaustion and emotional display.We hypothesized that e-motional labor mediated the relation between inhibiting negative emotion rule and exhaustion, and the relation be-tween expressing positive emotion rule and exhaustion.Rule commitment predict positively whether one perform the rules or not.Only one performs emotional displaying rules of the organization, emotional displaying may have effect on emotion exhaustion.Therefore, rule commitment moderated the relation between emotional displaying rules and exhaustion, and the relation between emotional displaying rules and emotional labor. We established a model presenting the emotional labor's mediating role and rule commitment's moderating role above.Structural equation model was used to test the hypothesis.Consistent with predictions, the results showed that inhibiting negative emotion rules can positively predict emotion exhaustion, and surface labor can positively predict emotion exhaustion.Meanwhile, surface labor mediated the relation between inhibiting negative emotion rules and exhaustion.However, expressing positive emotion rules can not predict emotion exhaustion, and surface labor do not mediated the relation between expressing positive emotion and emotion exhaustion.Commitment to emotion rules can not predict emotion exhaustion.Meanwhile, commitment to emotion rules moderate the relation

2016-04-01

Full Text Available Background: Teaching physical education is an emotion-laden context which requires physical education teachers to engage in emotional labor in order to foster their well-being, as well as student’s outcomes. Objective: The purpose of this study was to investigate the predictability of emotional labour strategies on job satisfaction and emotional exhaustion among secondary physical education teachers in South Korea. Specifically, the four forms of emotional labour (i.e., surface acting, deep acting, genuine positive expression, and genuine negative expression were hypothesized to have different influences on job satisfaction and emotional exhaustion. Method: A total of 225 full-time physical education teachers were invited to participate in the paper-pencil survey. The questionnaires contained items measuring the four forms of emotional labour, emotional exhaustion, and job satisfaction which had been modified to fit the physical education setting. Results: The results indicated that surface acting, genuine positive expression, and genuine expression was significantly associated with emotional exhaustion whereas only genuine positive expression was significantly associated with job satisfaction and emotional exhaustion. Finally, emotional exhaustion mediates the relationship between surface acting and job satisfaction, genuine positive expression and job satisfaction, and genuine negative expression and job satisfaction. Conclusion: These results suggest that emotional labour plays a critical role on physical education teachers’ well-being and job attitude.  Keywords: emotional regulation, physical education teacher, genuine expression, Asian culture, surface acting

Does Despotic Leadership Harm Employee Family Life: Exploring the Effects of Emotional Exhaustion and Anxiety.

Nauman, Shazia; Fatima, Tasneem; Haq, Inam Ul

2018-01-01

Research has not focused on the negative effects of despotic leadership on subordinates' life satisfaction and the interface between work and family. Drawing on the Conservation of Resources theory, this research investigates the mediating effect of emotional exhaustion through which despotic leadership transcends from the workplace to subordinates' personal lives, resulting in work-family conflict and decreased life satisfaction. The research also examines the moderating effect of subordinates' anxiety on the relationship of their perceptions of despotic leadership with work-family conflict and life satisfaction. Three waves of time-lagged data was collected from 224 book sellers who work in publishing houses. We used Hayes' PROCESS to test moderation and SEM to test mediation. The results of the study suggest that despotic leadership is related to work-family conflict via emotional exhaustion, but offer no support for its relationship with life satisfaction. As expected, when subordinates' anxiety increases, the positive relationship between a supervisor's despotism and his or her subordinates' work-family conflict and the negative relationship between despotic leadership and life satisfaction both strengthen.

Full Text Available Research has not focused on the negative effects of despotic leadership on subordinates’ life satisfaction and the interface between work and family. Drawing on the Conservation of Resources theory, this research investigates the mediating effect of emotional exhaustion through which despotic leadership transcends from the workplace to subordinates’ personal lives, resulting in work-family conflict and decreased life satisfaction. The research also examines the moderating effect of subordinates’ anxiety on the relationship of their perceptions of despotic leadership with work-family conflict and life satisfaction. Three waves of time-lagged data was collected from 224 book sellers who work in publishing houses. We used Hayes’ PROCESS to test moderation and SEM to test mediation. The results of the study suggest that despotic leadership is related to work-family conflict via emotional exhaustion, but offer no support for its relationship with life satisfaction. As expected, when subordinates’ anxiety increases, the positive relationship between a supervisor’s despotism and his or her subordinates’ work-family conflict and the negative relationship between despotic leadership and life satisfaction both strengthen. The results suggest that despotic leaders harm their subordinates’ non-work lives, and these effects intensify when subordinates have high levels of anxiety. These findings have important implications for service organizations in mitigating the negative effects of despotic leadership by minimizing subordinates’ anxiety through coping mechanisms and giving reward and incentives.

Nursing burnout is affected by various factors, including work overload. Since the inauguration of the Health Sector Evolution Plan (HSEP) in Iran in 2014, government hospitals have been required to provide health services to the public at all levels. This decision, however, has increased the volume of patients admitted to government hospitals. Because nurses are on the front line of health services, they are faced with a greater load of care provision. This study aimed to evaluate nursing burnout before and after HSEP in Iran, with an emphasis on the differences between government and private hospitals. This retrospective panel study used Maslach's burnout inventory to evaluate nursing burnout in 371 nurses working in government and private hospitals in Shiraz, Iran, before and 7 months after the health sector reform. Chi-square test and paired t test were used to compare burnout scores. The results showed that nursing burnout had changed significantly after HSEP was launched (p = .030). A more detailed assessment found that burnout and emotional exhaustion had both increased significantly in the government-hospital group (ps = .014 and .001, respectively). However, no significant change in burnout was found in the private-hospital group over the same period. The findings of this study indicate an increase in nursing burnout in government hospitals. An important issue in every health sector reform is nursing resource management, with a focus on burnout. Accordingly, policymakers should consider the work overload situation of nurses and work to prevent increased burnout, especially emotional exhaustion.

The impact of furloughs on emotional exhaustion, self-rated performance, and recovery experiences.

Halbesleben, Jonathon R B; Wheeler, Anthony R; Paustian-Underdahl, Samantha C

2013-05-01

The notion that strain can result as employees' resources are threatened or lost is well established. However, the transition from resource threats to resource losses is an important but understudied aspect of employee strain. We argue that the threat-to-loss transition triggers accelerated resource loss and a shift in how employees utilize their remaining resources unless employees engage in recovery experiences during the transition. Using a discontinuous change framework, we examine employee furloughs-the placement of employees on leave with no salary of any kind-in terms of the transition from resource threat to loss: Resources may be threatened when the furlough is announced and lost when the furlough occurs. Using 4 data collections with 180 state government employees, we found mean levels of emotional exhaustion increased and mean levels of self-reported performance decreased following the furlough. The discontinuous changes in exhaustion and performance were significantly impacted by employees' recovery experiences during the furlough. We discuss the implications of these findings for other threat-to-loss and recovery research as well as for organizations implementing furloughs.

The effects of age and drug dependency on the emotional exhaustion and job satisfaction of adult streetworkers in australia.

Cregan, Christina; Kulik, Carol T; Salinger, Dani

2013-07-01

This multi-method study investigated a sample of adult streetworkers (n = 107) in Melbourne, Australia in 2008. We contacted outdoor prostitutes through four "drop-in" centers run by not-for-profit organizations. Drug use was the over-riding common characteristic of most of these streetworkers. Using emotional labor theory as a theoretical framework, we hypothesized that individuals who worked on the streets solely to earn money to buy drugs would experience the highest levels of emotional exhaustion and the lowest levels of job satisfaction. We predicted these effects would be most evident for older drug dependent streetworkers. Content analysis of open-ended interview responses identified acting, age, and drug dependency as key themes. Moderator hierarchical regression analysis of responses to closed-ended questions with tests for mediation supported the hypotheses. It also demonstrated that older drug dependent streetworkers felt most trapped in their occupation and this sense of being locked-in was associated with emotional exhaustion but not with job satisfaction. The evidence that age and drug dependency affects the psychological outcomes associated with streetwork suggests that the efforts of police and the courts will be ineffective in dealing with people whose addiction traps them in an occupation that offers few intrinsic rewards. Decriminalization would encourage police to protect streetworkers from violence. Agencies could seek financial support to provide welfare and exit strategies.

2017-01-01

This study aimed to examine the effects of both hindrance and challenge demands on driving anger within the framework of the job demands-resources (JD-R) model. We collected self-reported data from 411 office workers driving to and from work each day in five cities in China. The results from a structural equation modeling analysis indicated that both hindrance and challenge demands were positively related to emotional exhaustion, which was in turn positively correlated with driving anger. Moreover, work engagement was positively correlated with driving anger. Implications of the present findings regarding both the JD-R model and driving safety research are discussed.

We investigate how emotional exhaustion (EE), the core component of burnout, relates to cognitive performance, job performance and health. Cognitive performance was assessed by self-rated cognitive stress symptoms, self-rated and peer-rated cognitive impairments in everyday tasks and a neuropsychological test of learning and memory (LGT-3); job performance and physical health were gauged by self-reports. Cross-sectional linear regression analyses in a sample of 100 teachers confirm that EE is negatively related to cognitive performance as assessed by self-rating and peer-rating as well as neuropsychological testing (all p Longitudinal linear regression analyses confirm similar trends (p longitudinal analyses, EE also significantly predicts physical health. Contrary to our expectations, EE does not affect job performance. When reversed causation is tested, none of the outcome variables at Time 1 predict EE at Time 2. This speaks against cognitive dysfunctioning serving as a vulnerability factor for exhaustion. In sum, results underpin the negative consequences of EE for cognitive performance and health, which are relevant for individuals and organizations alike. In this way, findings might contribute to the understanding of the burnout syndrome. Copyright © 2012 John Wiley & Sons, Ltd.

The Design and Development of Staff Wellbeing Initiatives: Staff Stressors, Burnout and Emotional Exhaustion at Children and Young People's Mental Health in Australia.

Mental health work presents problems for staff over and above those encountered in other organisations, including other areas of healthcare. Healthcare workers, in particular mental health workers, have poorer job satisfaction and higher job burnout and turnover compared with established norms for other occupational groups. To make sense of why healthcare workers experience high levels of burnout, a strong body of literature points to the emotionally demanding nature of people-work. The negative effects of mental health work on employee health can be mitigated by the provision of appropriate job resources and wellbeing initiatives. As to develop initiatives that appropriately target staff sources of stress and needs, it is important to engage staff in this process. As such, Children and Young People's Mental Health (CYPMH) and headspace Gosford, in Australia, New South Wales (NSW), developed a survey to identify how staff experience and manage the emotional demands of mental health work, what they identify as key stressors and which initiatives they would like to see implemented. Fifty-five staff (response rate of 73 %) completed the survey, and the results suggest that while staff find the work emotionally demanding, they do not appear to be emotionally exhausted and report administrative rather than client issues as their primary concerns. While a strong body of literature identifies the management of emotions in the workplace as a significant cause of stress, organisational stressors such as working in a bureaucratic environment are also important to understanding staff wellbeing.

Kinman, Gail; Leggetter, Sandra

2016-01-01

Although compassionate care has wide-ranging benefits for patients, it can be emotionally demanding for healthcare staff. This may be a particular problem for those with little experience in a caring role. This study utilises the job demands-resources model to examine links between “emotional labour” and emotional exhaustion in student nurses. In line with the triple-match principle—whereby interactive effects are more likely when job demands, resources, and outcomes are within the same qualitative domain—the protective role of emotional support and emotion-focused coping (i.e., emotional venting) in the relationship between emotional labour and exhaustion is also explored. An online questionnaire was completed by 351 student nurses with experience working in healthcare settings. A strong positive relationship was found between emotional labour and emotional exhaustion, and some support was found for the moderating effects of emotional support and emotion-focused coping. Ways to help student and qualified nurses develop the emotional resilience required to protect their wellbeing, while providing high-quality compassionate care to patients are considered.

So far, limited research has been carried out to better understand the interplay between the emotions, the use of emotion regulation strategies, and the well-being of professional caregivers of People with Dementia (PwD). This pilot study (N = 43 professional caregivers) aimed to (1) describe the type and frequency of emotions experienced at work; (2) analyze the associations between experienced emotions, emotion regulation strategies, and well-being; and (3) test whether the use of specific emotion regulation strategies moderates the relationship between experienced emotions and emotional exhaustion. In the challenging context of professionally caring for PwD, results suggest that (1) caregivers experience positive emotions more frequently than negative emotions; (2) caregivers using relatively inappropriate regulation strategies are more likely to experience negative emotions, less likely to experience positive emotions, and have poorer physical and mental health; and (3) expressive suppression significantly moderates the relationship between positive experienced emotions and emotional exhaustion. © The Author(s) 2015.

The downside of goal-focused leadership: the role of personality in subordinate exhaustion.

Perry, Sara Jansen; Witt, L A; Penney, Lisa M; Atwater, Leanne

Exhaustion has a significant impact on employees and organizations, and leader behavior may affect it. We applied conservation of resources theory to test propositions regarding the joint effects of goal-focused leadership (GFL) and personality on employee exhaustion. We proposed that the relationship between GFL and exhaustion depends on employees' standing on both conscientiousness and emotional stability. Specifically, we expected that high-conscientiousness subordinates experience greater compatibility with a goal-focused leader because of their predisposition to direct resources toward achievement and goal setting, resulting in lower exhaustion under such a leader than among low-conscientiousness employees. Furthermore, high emotional stability may compensate for GFL incompatibility among low-conscientiousness employees by providing additional resources to manage GFL. In contrast, employees low on both traits likely experience greater exhaustion under a goal-focused leader compared with other employees. Results revealed a 3-way interaction in 2 independent samples and were generally supportive of our predictions. GFL was associated with heightened exhaustion among individuals in the low-emotional-stability, low-conscientiousness group but not among workers having any other trait combination.

Full Text Available Teaching profession is considered emotionally demanding since teachers experience a variety of positive and negative emotions of significant intensity at work. Emotions they experience in relation to their professional activities can affect their professional and personal development. Frequent experiences of teachers' negative emotions in relation to students, parents, colleagues or educational system in general as well as feelings of emotional exhaustion (as an important aspect of burnout, can have a negative impact on teachers' psychological well-being and increase the occurrence of psychopathological symptoms. The aim of this study was to examine the role of emotions (experienced in relation to students, parents, and educational system and emotional exhaustion in explaining symptoms of anxiety, depression, and somatization among teachers. The study was conducted on a sample of 1149 subject-specific elementary school teachers from different regions in Croatia. A total of 210 male and 939 female teachers, aged between 24 and 65, participated in the study. Considering the expected gender differences in the prevalence of psychopathological symptoms, hierarchical regression analyses were conducted separately on the subsamples of male and female teachers. Results showed that, after controlling for working experience (which explains the somatization symptoms, certain emotions (exhaustion, love, anger, and hopelessness experienced in relation to students; anxiety experienced in relation to parents; and disappointment with educational system and emotional exhaustion significantly explain the symptoms of anxiety, depression, and somatization among teachers. The obtained results emphasise the importance of emotional exhaustion, which results from daily stressors and pressures at work, in explaining psychopathological outcomes in the teaching profession.

There is increasing recognition that physician wellness is critical; it not only benefits the provider, but also influences quality and patient care outcomes. Despite this, resident physicians suffer from a high rate of burnout and personal distress. Individuals with higher emotional intelligence (EI) are thought to perceive, process, and regulate emotions more effectively, which can lead to enhanced well-being and less emotional disturbance. This study sought to understand the relationship between EI and wellness among surgical residents. Residents in a single general surgery residency program were surveyed on a voluntary basis. Emotional intelligence was measured using the Trait Emotional Intelligence Questionnaire-Short Form. Resident wellness was assessed with the Dupuy Psychological General Well-Being Index, Maslach Burnout Inventory, and Beck Depression Inventory-Short Form. Emotional intelligence and wellness parameters were correlated using Pearson coefficients. Multivariate analysis was performed to identify factors predictive of well-being. Seventy-three residents participated in the survey (response rate 63%). Emotional intelligence scores correlated positively with psychological well-being (r = 0.74; p emotional exhaustion (r = -0.69; p emotional exhaustion (β = -0.63; p Emotional intelligence is a strong predictor of resident well-being. Prospectively measuring EI can identify those who are most likely to thrive in surgical residency. Interventions to increase EI can be effective at optimizing the wellness of residents.

Full Text Available The use of emotions in the workplace has begun to be increasingly studied by theorists and researchers in organizational behavior. One essential construct in the literature is the emotional labor which is perceived to be the management of feelings to express organizationally desired emotions. This article aims to review existing perspectives on emotional labor, to differentiate the concepts of emotional labor and emotional dissonance, to analyze emotion regulation strategies, and to discuss the consequences of emotional labor in the workplace. These clarifications with regard to the emotional labor and its mechanisms can help manage their associated negative outcomes (such as emotional exhaustion, lower job satisfaction, higher levels of burnout, and intentions to quit the job and sustain their possible positive outcomes (such as feelings of accomplishment and enhanced identification with the work role.

The aim of this study was to assess the effectiveness of the job demands-resources (JD-R) model in explaining the relationship of job demands and resources with safety outcomes (i.e., workplace injuries and near-misses). We collected self-reported data from 670 crude oil production workers from three sub-companies of a major oilfield company in China. The results of a structural equation analysis indicated that job demands (psychological and physical demands) and job resources (decision latitude, supervisor support and coworker support) could affect emotional exhaustion and safety compliance, and thus influence the occurrence of injuries and near-misses. The implications of the present findings regarding both the JD-R model and occupational safety research were discussed. Copyright © 2012 Elsevier Ltd. All rights reserved.

Workplace surface acting and marital partner discontent: Anxiety and exhaustion spillover mechanisms.

Krannitz, Morgan A; Grandey, Alicia A; Liu, Songqi; Almeida, David A

2015-07-01

Surface acting (i.e., faking and suppressing emotions at work) is repeatedly linked to employee negative moods and emotional exhaustion, but the consequences may also go beyond work boundaries. We provide a unique theoretical integration of these 2 emotional labor consequences with 2 work-to-family conflict mechanisms, mood spillover and resource drain, to explain why surface acting is likely to create marital partner discontent (i.e., partner's perceived work-to-family conflict and desire for the employee to quit). A survey of 197 hotel managers and their marital partners supported that managers' surface acting was directly related to their partner wanting them to quit, and indirectly to partner's perception of work-to-family conflict via exhaustion consistent with the resource drain mechanism. Anxiety from surface acting had an indirect mediating effect on marital partner discontent through exhaustion. Importantly, controlling for dispositional negativity and job demands did not weaken these effects. Implications for theory and future research integrating work-family and emotional labor are discussed. (c) 2015 APA, all rights reserved).

Executive control, ERP and pro-inflammatory activity in emotionally exhausted middle-aged employees. Comparison between subclinical burnout and mild to moderate depression.

Burnout is a syndrome occurring mainly in individuals with long-term stressful work. The main complaints are emotional exhaustion and reduced performance. Burnout also largely overlaps with depression. Both are characterized by increased incidence of infections due to dysregulation of the immune system, overexpression of pro-inflammatory cytokines and cognitive deficits, particularly related to executive functions. To distinguish between burnout and depression already at the pre-clinical stage, the present double-blinded study compared immunological and cognitive parameters in seventy-six employees from emotionally demanding occupations who were post-hoc subdivided into two groups scoring low (EE-) and high (EE+) in emotional exhaustion and low (DE-) and high (DE+) in depression. Immunological parameters were measured from blood samples. Executive functions were studied by analyzing event-related brain potentials (ERPs) and performance during a task switching paradigm. Psychosocial job parameters were measured with standardized questionnaires. Burnout and mild to moderate depression largely overlapped. However, several subjects showed burnout without depressive symptoms. Higher levels of the pro-inflammatory cytokines IL-6 and IL-12 were correlated with burnout severity and depressive symptoms in male individuals. In the switch task a trend for lower performance in the EE+ vs. EE- group and no difference between DE+ and DE- groups were found. In the ERPs, however, differences were observed which distinguished between subclinical burnout and depression: the terminal contingent negative variation (CNV), indicating preparatory activity and the P3b, related to allocation of cognitive resources were generally reduced in EE+ vs. EE-, whereas no differences were found in the DE+ vs. DE- groups. The frontal P3a was selectively reduced in switch trials in the EE+ vs. EE- group and showed only a trend in DE+ vs. DE-, indicating impairment of executive control in subclinical

This multilevel longitudinal study investigates a newly identified climate construct, psychosocial safety climate (PSC), as a precursor to job characteristics (e.g., emotional demands), and psychological outcomes (i.e., emotional exhaustion and depression). We argued that PSC, as an organizational climate construct, has cross-level effects on individually perceived job design and psychological outcomes. We hypothesized a mediation process between PSC and emotional exhaustion particularly through emotional demands. In sequence, we predicted that emotional exhaustion would predict depression. At Time 1, data were collected from employees in 36 Malaysian private sector organizations (80% responses rate), n = 253 (56%), and at Time 2 from 27 organizations (60%) and n = 117 (46%). Using hierarchical linear modeling (HLM), we found that there were cross-level effects of PSC Time 1 on emotional demands Time 2 and emotional exhaustion Time 2, but not on depression Time 2, across a 3-month time lag. We found evidence for a lagged mediated effect; emotional demands mediated the relationship between PSC and emotional exhaustion. Emotional exhaustion did not predict depression. Finally, our results suggest that PSC is an important organizational climate construct, and acts to reduce employee psychological problems in the workplace, via working conditions.

Vagally mediated heart rate variability (vmHRV) is a measure of cardiac vagal tone, and is widely viewed as a physiological index of the capacity to regulate emotions. However, studies have not directly tested whether vmHRV is associated with the ability to facially express emotions. In extending prior work, the current report tested links between resting vmHRV and the objectively assessed ability to facially express emotions, hypothesizing that higher vmHRV would predict greater expressive skill. Eighty healthy women completed self-reported measures, before attending a laboratory session in which vmHRV and the ability to express six emotions in the face were assessed. A repeated measures analysis of variance revealed a marginal main effect for vmHRV on skill overall; individuals with higher resting vmHRV were only better able to deliberately facially express anger and interest. Findings suggest that differences in resting vmHRV are associated with the objectively assessed ability to facially express some, but not all, emotions, with potential implications for health and well-being. © 2016 Society for Psychophysiological Research.

An improved exhaust system for an internal combustion gasoline-and/or diesel-fueled engine includes an engine exhaust manifold which has been fabricated from carbon- carbon composite materials in operative association with an exhaust pipe ducting which has been fabricated from carbon-carbon composite materials. When compared to conventional steel. cast iron. or ceramic-lined iron paris. the use of carbon-carbon composite exhaust-gas manifolds and exhaust pipe ducting reduces the overall weight of the engine. which allows for improved acceleration and fuel efficiency: permits operation at higher temperatures without a loss of strength: reduces the "through-the wall" heat loss, which increases engine cycle and turbocharger efficiency and ensures faster "light-off" of catalytic converters: and, with an optional thermal reactor, reduces emission of major pollutants, i.e. hydrocarbons and carbon monoxide.

2017-12-01

Full Text Available A person-oriented approach was applied to identify profiles of study engagement and burnout (i.e., exhaustion, cynicism, inadequacy in higher education in a large and representative sample of 12,394 higher education students at different phases of their studies in universities and polytechnics in Finland. Four profiles were identified: Engaged (44%, engaged-exhausted (30% inefficacious (19% and burned-out (7%. The engaged students had the most positive engagement accompanied with the least burnout symptoms compared to other groups. The engaged-exhausted students experienced emotional exhaustion simultaneously with academic engagement. The inefficacious group had heightened experience of inadequacy as a student. The burned-out students showed very high cynicism and inadequacy and very low academic engagement compared to the other groups. Of these groups, the engaged students tended to be in the earlier stages in their studies, whereas the burned-out and inefficacious students had been studying the longest. The pattern suggests that students starting out with high engagement and that burnout becomes more common later in the academic career. Supporting demands-resources model, the covariates reflecting the demands were higher and those reflecting resources were lower among the burned-out and inefficacious students compared to the engaged students.

This study investigated whether a 7-week yoga intervention could improve physical function, perceived stress, and mental/emotional wellness in elderly participants. 8 participants (66.5 ± 0.3 years) attended 2 60-min Hatha yoga sessions/week for 7 weeks, and performed pre- and post-intervention assessments. Balance was assessed using a 5-test battery. Flexibility was measured by sit-and-reach and shoulder flexibility tests. Functional mobility tests included 8-ft up-and-go, 5 chair stands, and 4-m walk. Participants completed SF-12, exhaustion level, and Perceived Stress Scale (PSS) questionnaires. SF-12 Mental Component Summary scores, exhaustion levels, and PSS scores improved post-intervention. No differences were found for physical function measures. Yoga participation can improve mental/emotional wellness, exhaustion levels, and stress levels in elderly individuals, even without measurable improvements in physical function. Clinicians and health practitioners who work with the elderly should consider yoga as a potential therapeutic modality for improving important aspects of quality of life in this population.

Golonka, Krystyna; Mojsa-Kaja, Justyna; Popiel, Katarzyna; Marek, Tadeusz; Gawlowska, Magda

2017-01-01

The substantial body of research employing subjective measures indicates that burnout syndrome is associated with cognitive and emotional dysfunctions. The growing amount of neurophysiological and neuroimaging research helps in broadening existing knowledge of the neural mechanisms underlying core burnout components (emotional exhaustion and depersonalization/cynicism) that are inextricably associated with emotional processing. In the presented EEG study, a group of 93 participants (55 women; mean age = 35.8) were selected for the burnout group or the demographically matched control group on the basis of the results of the Maslach Burnout Inventory - General Survey (MBI-GS) and the Areas of Worklife Survey (AWS). Subjects then participated in an EEG experiment using two experimental procedures: a facial recognition task and viewing of passive pictures. The study focuses on analyzing event-related potentials (ERPs): N170, VPP, EPN, and LPP, as indicators of emotional information processing. Our results show that burnout subjects, as compared to the control group, demonstrate significantly weaker response to affect-evoking stimuli, indexed by a decline in VPP amplitude to emotional faces and decreased EPN amplitude in processing emotional scenes. The analysis of N170 and LPP showed no significant between-group difference. The correlation analyses revealed that VPP and EPN, which are ERP components related to emotional processing, are associated with two core burnout symptoms: emotional exhaustion and cynicism. To our knowledge, we are one of the first research groups to use ERPs to demonstrate such a relationship between neurophysiological activity and burnout syndrome in the context of emotional processing. Thus, in conclusion we emphasized that the decreased amplitude of VPP and EPN components in the burnout group may be a neurophysiological manifestation of emotional blunting and may be considered as neurophysiological markers of emotional exhaustion and cynicism

Do emotional support and classroom organization earlier in the year set the stage for higher quality instruction?

Curby, Timothy W; Rimm-Kaufman, Sara E; Abry, Tashia

2013-10-01

Many teachers believe that providing greater emotional and organizational supports in the beginning of the year strengthens their ability to teach effectively as the year progresses. Some interventions, such as the Responsive Classroom (RC) approach, explicitly embed this sequence into professional development efforts. We tested the hypothesis that earlier emotional and organizational supports set the stage for improved instruction later in the year in a sample of third- and fourth-grade teachers enrolled in a randomized controlled trial of the RC approach. Further, we examined the extent to which the model generalized for teachers using varying levels of RC practices as well as whether or not teachers were in the intervention or control groups. Teachers' emotional, organizational, and instructional interactions were observed using the Classroom Assessment Scoring System (Pianta, La Paro, & Hamre, 2008) on five occasions throughout the year. Results indicated a reciprocal relation between emotional and instructional supports. Specifically, higher levels of emotional support earlier in the year predicted higher instructional support later in the year. Also, higher levels of instructional support earlier in the year predicted higher emotional support later in the year. Classroom organization was not found to have longitudinal associations with the other domains across a year. This pattern was robust when controlling for the use of RC practices as well as across intervention and control groups. Further, teachers' use of RC practices predicted higher emotional support and classroom organization throughout the year, suggesting the malleability of this teacher characteristic. Discussion highlights the connection between teachers' emotional and instructional supports and how the use of RC practices improves teachers' emotionally supportive interactions with students.

Service with a smile: do emotional intelligence, gender, and autonomy moderate the emotional labor process?

Science.gov (United States)

Johnson, Hazel-Anne M; Spector, Paul E

2007-10-01

This survey study of 176 participants from eight customer service organizations investigated how individual factors moderate the impact of emotional labor strategies on employee well-being. Hierarchical regression analyses indicated that gender and autonomy were significant moderators of the relationships between emotional labor strategies and the personal outcomes of emotional exhaustion, affective well-being, and job satisfaction. Females were more likely to experience negative consequences when engaging in surface acting. Autonomy served to alleviate negative outcomes for individuals who used emotional labor strategies often. Contrary to our hypotheses, emotional intelligence did not moderate the relationship between the emotional labor strategies and personal outcomes. Results demonstrated how the emotional labor process can influence employee well-being. (c) 2007 APA, all rights reserved.

Emotional labor actors: a latent profile analysis of emotional labor strategies.

Science.gov (United States)

Gabriel, Allison S; Daniels, Michael A; Diefendorff, James M; Greguras, Gary J

2015-05-01

Research on emotional labor focuses on how employees utilize 2 main regulation strategies-surface acting (i.e., faking one's felt emotions) and deep acting (i.e., attempting to feel required emotions)-to adhere to emotional expectations of their jobs. To date, researchers largely have considered how each strategy functions to predict outcomes in isolation. However, this variable-centered perspective ignores the possibility that there are subpopulations of employees who may differ in their combined use of surface and deep acting. To address this issue, we conducted 2 studies that examined surface acting and deep acting from a person-centered perspective. Using latent profile analysis, we identified 5 emotional labor profiles-non-actors, low actors, surface actors, deep actors, and regulators-and found that these actor profiles were distinguished by several emotional labor antecedents (positive affectivity, negative affectivity, display rules, customer orientation, and emotion demands-abilities fit) and differentially predicted employee outcomes (emotional exhaustion, job satisfaction, and felt inauthenticity). Our results reveal new insights into the nature of emotion regulation in emotional labor contexts and how different employees may characteristically use distinct combinations of emotion regulation strategies to manage their emotional expressions at work.

Chou, Huei Yin; Hecker, Rob; Martin, Angela

2012-05-01

The aim of the present study was to investigate the effects of job demands and resources as well as emotional labour on job satisfaction and emotional exhaustion among nurses. While emotional labour is a construct that has considerable significance in health care as nurses often need to express organizationally desired emotions, little research has investigated the relationships between emotional labour, job demands and resources in the prediction of nurses' well-being. The questionnaire was distributed to 450 registered nurses (RN) working in a teaching hospital in Taiwan during February 2007, of which 240 valid questionnaires were returned and analysed (53.33% response rate). In addition to descriptive statistics and correlation, structural equation modelling (LISREL 8.8) was conducted. The findings showed that the frequency of interacting with difficult patients positively related to surface acting. Perceived organizational support (POS) positively related to deep acting and negatively to surface acting. The results also showed that surface acting related negatively, and deep acting related positively, to job satisfaction. The frequency of interactions with difficult patients related positively to emotional exhaustion, and negatively to job satisfaction. Perceived organizational support related negatively to emotional exhaustion and positively to job satisfaction. The results suggest that job demands, resources and emotional labour can predict nurses' well-being. The results of the present study indicate that nurses' well-being can be predicted by job demands, resources and emotional labour. There is a need to address organizational support and training programmes to enhance job satisfaction and reduce emotional exhaustion among nurses. © 2011 Blackwell Publishing Ltd.

Szczepanowski, Remigiusz; Traczyk, Jakub; Wierzchoń, Michał; Cleeremans, Axel

2013-03-01

Here, we explore the sensitivity of different awareness scales in revealing conscious reports on visual emotion perception. Participants were exposed to a backward masking task involving fearful faces and asked to rate their conscious awareness in perceiving emotion in facial expression using three different subjective measures: confidence ratings (CRs), with the conventional taxonomy of certainty, the perceptual awareness scale (PAS), through which participants categorize "raw" visual experience, and post-decision wagering (PDW), which involves economic categorization. Our results show that the CR measure was the most exhaustive and the most graded. In contrast, the PAS and PDW measures suggested instead that consciousness of emotional stimuli is dichotomous. Possible explanations of the inconsistency were discussed. Finally, our results also indicate that PDW biases awareness ratings by enhancing first-order accuracy of emotion perception. This effect was possibly a result of higher motivation induced by monetary incentives. Copyright © 2012 Elsevier Inc. All rights reserved.

Emotional intelligence and learning & teaching in higher education : implications for bioscience education

Emotional Intelligence (EI) was popularised in 1990s by Daniel Goleman’s bestselling book of the same name (Goleman 1996). EI has been criticised by scholars in the psychological community for lack of a clear definition or empirical evidence that it is anything more than a combination of already known cognitive and personality factors. Despite this controversy, there are many proponents of EI in higher education who highlight the folly of trying to separate the cognitive from the emotional. T...

Academic Self-Efficacy, Emotional Intelligence, GPA and Academic Procrastination in Higher Education

Directory of Open Access Journals (Sweden)

Meirav Hen

2014-05-01

Full Text Available Academic procrastination has been seen as an impediment to students' academic success because it decreases the quality and quantity of learning while increasing the severity of negative outcomes in students’ lives. Research findings suggest that academic procrastination is closely related to motivation variables such as self-efficacy and self-regulated learning, and with higher levels of anxiety, stress, and illness. Emotional Intelligence is the ability to assess, regulate, and utilize emotions. It has been found to be associated with academic self-efficacy and a variety of better outcomes, including academic performance. The purpose of the present study was to explore and provide an initial understanding to the relationships between emotional intelligence, academic procrastination and GPA, as mediated by academic selfefficacy. A convenience sampling of 287 college students was collected. Structural equation modeling analysis using AMOS was conducted to examine the mediation role of academic selfefficacy between emotional intelligence, procrastination and GPA. Findings indicated that Emotional intelligence has a negative indirect effect on academic procrastination and a positive indirect effect on academic performance. Further research is needed to explore the effect of emotional intelligence on academic procrastination and performance, and to further understand its implications for academic settings.

Full Text Available Orientation: This study contributes to an in-depth understanding of emotional intelligence (EI in women leaders in Higher Education Institutions (HEIs in South Africa from an inside perspective. Research purpose: The purpose of this study is to explore EI in South African women leaders working in HEIs to identify women leader’s strengths, foci and their possible areas of development. The aim is to get deeper insights in EI in women leaders because EI is associated with effective leadership qualities, creativity and innovation, as well as empathetic communication which is needed in the challenging HEI workplaces. Motivation for the study: Emotional intelligence is an important source for women leaders to increase leadership qualities. This study is motivated by a deep interest to explore aspects of EI in women leaders in this specific professional context. Research design, approach and method: The study uses a qualitative research design and an approach based on Dilthey’s modern hermeneutics of ‘Verstehen’ (understanding. Twenty-three women leaders of the Higher Education Research Service (HERS-SA network were interviewed through semi-structured interviews. One researcher observed behaviour in one HEI to support the interpretation of the data. Data were analysed through content analysis. Main findings: Findings show that women leaders mainly refer to intrapersonal emotional quotient (EQ, followed by interpersonal EQ, adaptability, stress management and, finally, general mood. The most highly rated components of EQ are self-regard, followed by interpersonal relationships, problem solving, empathy, emotional self-awareness, assertiveness, impulse control and social responsibility. Findings also provide ideas on what EQ components can be further developed. Practical/managerial implications: New insights are provided on what components of EI should be developed in women leaders to increase overall EI, on cognitive and behavioural levels

Teachers' feeling of belonging, exhaustion, and job satisfaction: the role of school goal structure and value consonance.

Science.gov (United States)

Skaalvik, Einar M; Skaalvik, Sidsel

2011-07-01

In their daily teaching and classroom management, teachers inevitably communicate and represent values. The purpose of this study was to explore relations between teachers' perception of school level values represented by the goal structure of the school and value consonance (the degree to which they felt that they shared the prevailing norms and values at the school), teachers' feeling of belonging, emotional exhaustion, job satisfaction, and motivation to leave the teaching profession. The participants were 231 Norwegian teachers in elementary school and middle school. Data were analyzed by means of structural equation modeling (SEM). Teachers' perception of mastery goal structure was strongly and positively related to value consonance and negatively related to emotional exhaustion, whereas performance goal structure, in the SEM model, was not significantly related to these constructs. Furthermore, value consonance was positively related to teachers' feeling of belonging and job satisfaction, whereas emotional exhaustion was negatively associated with job satisfaction. Job satisfaction was the strongest predictor of motivation to leave the teaching profession. A practical implication of the study is that educational goals and values should be explicitly discussed and clarified, both by education authorities and at the school level.

2013-06-01

To determine the prevalence of professional exhaustion syndrome (burnout) in dentists and to analyze possible sociodemographic and occupational risk factors . An observational, descriptive and cross-sectional survey of 203 dental staff of the Metropolitan Zone of Guadalajara, Mexico, from the Mexican Social Security Institute, University of Guadalajara, and those in private practice. A self-reported identification form and the Maslach Burnout Inventory-Human Services Survey were used to gather data. Descriptive statistics and inferential analyzes were performed using SPSS 15.0 support and EpiInfo V6.1. There was an 88.3% response. Professional exhaustion syndrome (burnout) was detected in 52.2% of them. Significant differences were obtained depending on the employment contract. A negative correlation was observed between the subscales emotional exhaustion and depersonalization, and a positive one between the lack of personal accomplishment at work. Professional exhaustion syndrome (burnout) is common (52.2%) for dentists, their possible risk factors: working in a public institution, being male, over 40 years, without a regular partner, and with more than 15 years with a partner, not having children, being a specialist with 10 years or more in an institution and the current job, morning shift, permanent recruitment, and having another job. The involvement of emotional exhaustion behaves like the syndrome. Average levels of the subscales are generally near normal. A negative correlation was found between the subscales emotional exhaustion and depersonalization, and positive between the lack of personal fulfillment at work with the presence of the syndrome. This leads us to consider the need for preventive measures in the workplace and personnel, as well as intervention programs at an individual, social or organizational level to reduce the prevalence found.

At least a pair of exhaust valves are provided and each supply a separate power extraction device. The first exhaust valves connect to a power turbine used to provide additional power to the engine either mechanically or electrically. The flow path from these exhaust valves is smaller in area and volume than a second flow path which is used to deliver products of combustion to a turbocharger turbine. The timing of the exhaust valve events is controlled to produce a higher grade of energy to the power turbine and enhance the ability to extract power from the combustion process.

Emotional labour in mental health nursing: An integrative systematic review.

Science.gov (United States)

Edward, Karen-Leigh; Hercelinskyj, Gylo; Giandinoto, Jo-Ann

2017-06-01

Emotional labour is the effort consumed by suppressing one's own emotions to care for others effectively while also caring for oneself. Mental health nurses are required to engage in effective therapeutic interactions in emotionally-intense situations. The aim of the present integrative systematic review was to investigate the emotional labour of mental health work and how this manifested, the impacts, and the ways to mitigate these impacts. In June 2016, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology, a systematic search of the bibliographic databases was undertaken to identify relevant literature. Screening, data extraction, and synthesis were performed by three reviewers. The inclusion criteria included any original research that investigated the emotional work of mental health nurses. We identified a total of 20 papers to be included in this review. Thematic synthesis of the findings revealed three emergent themes: emotional labour and caring, emotional exhaustion, and self-protection (expressed as emotional intelligence). Emotional labour, emotional exhaustion, and emotional intelligence were considered to be intrinsically linked, where they were both the influencing factor for burnout and a contributor to attrition. The results highlighted that emotional labour could inspire the development and personal growth of emotional intelligence in mental health nurses. In light of these findings, recommendations for clinical practice were considered; they included supportive work environments, involving nurses in shared decision-making, and the provision of ongoing professional development opportunities that facilitate the development of emotional intelligence and resilience. © 2017 Australian College of Mental Health Nurses Inc.

Full Text Available Previous research has revealed that perfectionists have a higher burnout risk than others, but the mechanisms accounting for this association have rarely been examined. The present study proposes that workaholism mediates this relation, as previous research revealed that (a perfectionists are more likely to be workaholics than others, and (b workaholics have a higher burnout risk than others. Using cross-sectional data from 199 Dutch managers, regression analyses revealed that holding high standards towards oneself (a self-directed indicator of perfectionism was unrelated to any of the three dimensions of the Maslach Burnout Inventory. However, high concern over making mistakes in the face of others (representing socially prescribed perfectionism was systematically associated with high levels of burnout and workaholism. Moreover, workaholism was positively associated with high levels of exhaustion. Subsequent mediation analysis revealed that the association between (the socially prescribed aspect of perfectionism and burnout (emotional exhaustion was mediated by workaholism.

Emotional creativity is defined as the ability to feel and express emotions in a new, effective and authentic way. There are currently no Basque-language self-report instruments to provide valid and reliable measures of this construct. Thus, this paper describes the process of adapting and validating the Emotional Creativity Inventory (ECI) for the Basque-speaking population. The sample was comprised of 594 higher education students (388 women and 206 men) aged between 18 and 32 years old (Mage = 20.47; SD = 2.48). The Basque version of the ECI was administered along with the TMMS-23, NEO PI-R, and PANAS. The results of exploratory and confirmatory factor analyses on the Basque ECI corroborated the original scale's three-factor structure (preparedness, novelty, and effectiveness/authenticity). Those dimensions showed acceptable indexes of internal consistency (α = .80, .83, and .83) and temporal stability (r = .70, .69, and .74). The study also provided some evidence of external validity (p emotional creativity and emotional intelligence, personality, affect, and sex. The Basque ECI can be regarded as a useful tool to evaluate perceived emotional creativity during the preparation and verification phases of the creative process.

Full Text Available Critical-care nurses often look after three or more critically-ill patients during a shift. The workload and emotional stress can lead to disharmony between the nurse’s body, mind and spirit. Nurses with a high emotional intelligence have less emotional exhaustion and psychosomatic symptoms; they enjoy better emotional health; gain more satisfaction from their actions (both at work and at home; and have improved relationships with colleagues at work. The question arises: what is the emotional intelligence of critical-care nurses? A quantitative survey was conducted. The target population was registered nurses working in critical-care units who attended the Critical Care Congress 2009 (N = 380. Data were collected with the use of the Trait Emotional Intelligence Short Form and analysed using the Statistical Package for the Social Sciences software. The sample (n= 220 was mainly a mature, female and professionally-experienced group of registered nurses. They held a variety of job descriptions within various critical-care units. Statistics indicated that the standard deviations were small and no aberrant aspects such as demographics skewed the findings. The conclusion was made that registered nurses who are older and that have more experience in critical care appear to have a higher range of emotional intelligence.

2012-03-01

This paper aims to investigate the relationship between teacher's personality types, emotional intelligence and burnout and to predict the burnout levels of 147 teachers in the city of Mashhad (Iran). To this end, we have used three inventories: Maslach Burnout Inventory (MBI), NEO Five Factor Inventory (NEO-FFI), and Emotional Quotient Inventory (EQ-I). We used Homogeneity Analysis and Multiple Linear Regression to analyze the data. The results exhibited a significant relationship between personality types and emotional intelligence and the three dimensions of burnout. It was indicated that the best predictors for emotional exhaustion were neuroticism and extroversion, for depersonalization were intrapersonal scale of emotional intelligence and agreeableness, and for personal accomplishment were interpersonal scale and conscientiousness. Finally, the results were discussed in the context of teacher burnout.

The auto-road complex brings the considerable contribution to pollution and adverse change of environment. Influence of exhaust gases of cars is at the bottom of occurrence and developments of various forms of diseases. Every townsman feels the negative influence rendered by motor transport on himself. The modern city dweller is so accustomed to the smell of exhaust gases that he does not even notice it at all, continues to breathe a poisonous mixture, while neither the car nor the road can be isolated from the habitats of people. The higher the population density, the higher the need for motor transport. The health effects of emissions of exhaust gases and vapors, including regulated and unregulated pollutants, are discussed in this article.

Road tunnels act like large laboratories; they provide an excellent environment to quantify atmospheric particles emission factors from exhaust and non-exhaust sources due to their known boundary conditions. Current work compares the High Volume, Dichotomous Stacked Filter Unit and Partisol Air Sampler for coarse, PM_1_0 and PM_2_._5 particle concentration measurement and found that they do not differ significantly (p = 95%). PM_2_._5 fraction contributes 66% of PM_1_0 proportions and significantly influenced by traffic (turbulence) and meteorological conditions. Mass emission factors for PM_1_0 varies from 21.3 ± 1.9 to 28.8 ± 3.4 mg/vkm and composed of Motorcycle (0.0003–0.001 mg/vkm), Cars (26.1–33.4 mg/vkm), LDVs (2.4–3.0 mg/vkm), HDVs (2.2–2.8 mg/vkm) and Buses (0.1 mg/vkm). Based on Lawrence et al. (2013), source apportionment modelling, the PM_1_0 emission of brake wear (3.8–4.4 mg/vkm), petrol exhaust (3.9–4.5 mg/vkm), diesel exhaust (7.2–8.3 mg/vkm), re-suspension (9–10.4 mg/vkm), road surface wear (3.9–4.5 mg/vkm), and unexplained (7.2 mg/vkm) were also calculated. The current study determined that the combined non-exhaust fleet PM_1_0 emission factor (16.7–19.3 mg/vkm) are higher than the combined exhaust emission factor (11.1–12.8 mg/vkm). Thus, highlight the significance of non-exhaust emissions and the need for legislation and abatement strategies to reduce their contributions to ambient PM concentrations. - Highlights: • Calculations of exhaust/non-exhaust particulate emission factors using tunnel sampling and source apportionment techniques. • Non-exhaust emission dominates in the fine particle fraction, considered responsible for adverse human health impacts. • Emission factors for non-exhaust sources (e.g. tyre and brake) were calculated. • Fleet source PM_1_0 emission factor were also calculated, which can be used in dispersion modelling and health risk assessment. • Tukey mean

2015-01-01

Recent research has attempted to explain the mechanisms through which parental attachment affects social and emotional outcomes (e.g., Burnette, Taylor, Worthington, & Forsyth, 2007 ; Panfile & Laible, 2012 ). The authors' goal was to examine negative emotionality and emotion regulation as mediators of the associations that attachment has with empathy, forgiveness, guilt, and jealousy. One hundred forty-eight adolescents reported their parental attachment security, general levels of negative emotionality and abilities to regulate emotional responses, and tendencies to feel empathy, forgiveness, guilt, and jealousy. Results revealed that attachment security was associated with higher levels of empathy, forgiveness, and guilt, but lower levels of jealousy. In addition, emotion regulation mediated the links attachment shared with both empathy and guilt, such that higher levels of attachment security were linked with greater levels of emotion regulation, which led to greater levels of empathy and guilt. Alternatively, negative emotionality mediated the links attachment shared with both forgiveness and jealousy, such that higher levels of attachment security were associated with lower levels of negative emotionality, which in turn was linked to lower levels of forgiveness and higher levels of jealousy. This study provides a general picture of how attachment security may play a role in shaping an individual's levels of social emotions.

Duffy, Kevin P [Metamora, IL; Kieser, Andrew J [Morton, IL; Rodman, Anthony [Chillicothe, IL; Liechty, Michael P [Chillicothe, IL; Hergart, Carl-Anders [Peoria, IL; Hardy, William L [Peoria, IL

2008-05-27

A homogeneous charge compression ignition engine operates by injecting liquid fuel directly in a combustion chamber, and mixing the fuel with recirculated exhaust and fresh air through an auto ignition condition of the fuel. The engine includes at least one turbocharger for extracting energy from the engine exhaust and using that energy to boost intake pressure of recirculated exhaust gas and fresh air. Elevated proportions of exhaust gas recirculated to the engine are attained by throttling the fresh air inlet supply. These elevated exhaust gas recirculation rates allow the HCCI engine to be operated at higher speeds and loads rendering the HCCI engine a more viable alternative to a conventional diesel engine.

Performance of Installed Cooking Exhaust Devices

Energy Technology Data Exchange (ETDEWEB)

Singer, Brett C.; Delp, William W.; Apte, Michael G.; Price, Philip N.

2011-11-01

The performance metrics of airflow, sound, and combustion product capture efficiency (CE) were measured for a convenience sample of fifteen cooking exhaust devices, as installed in residences. Results were analyzed to quantify the impact of various device- and installation-dependent parameters on CE. Measured maximum airflows were 70% or lower than values noted on product literature for 10 of the devices. Above-the-cooktop devices with flat bottom surfaces (no capture hood) – including exhaust fan/microwave combination appliances – were found to have much lower CE at similar flow rates, compared to devices with capture hoods. For almost all exhaust devices and especially for rear-mounted downdraft exhaust and microwaves, CE was substantially higher for back compared with front burner use. Flow rate, and the extent to which the exhaust device extends over the burners that are in use, also had a large effect on CE. A flow rate of 95 liters per second (200 cubic feet per minute) was necessary, but not sufficient, to attain capture efficiency in excess of 75% for the front burners. A-weighted sound levels in kitchens exceeded 57 dB when operating at the highest fan setting for all 14 devices evaluated for sound performance.

To test the hypothesis that toddlers at highest risk for behavioral problems from the most economically vulnerable families will benefit most from maternal talk about emotions. This study included 89 toddlers and mothers from low-income families. Behavioral problems were rated at 2 time points by masters-level trained Early Head Start home visiting specialists. Maternal emotion talk was coded from a wordless book-sharing task. Coding focused on mothers' emotion bridging, which included labeling emotions, explaining the context of emotions, noting the behavioral cues of emotions, and linking emotions to toddlers' own experiences. Maternal demographic risk reflected a composite score of 5 risk factors. A significant 3-way interaction between Time 1 toddler behavior problems, maternal emotion talk, and maternal demographic risk (p = .001) and examination of slope difference tests revealed that when maternal demographic risk was greater, more maternal emotion talk buffered associations between earlier and later behavior problems. Greater demographic risk and lower maternal emotion talk intensified Time 1 behavior problems as a predictor of Time 2 behavior problems. The model explained 54% of the variance in toddlers' Time 2 behavior problems. Analyses controlled for maternal warmth to better examine the unique contributions of emotion bridging to toddlers' behaviors. Toddlers at highest risk, those with more early behavioral problems from higher demographic-risk families, benefit the most from mothers' emotion talk. Informing parents about the use of emotion talk may be a cost-effective, simple strategy to support at-risk toddlers' social-emotional development and reduce behavioral problems.

Durkin, Sarah; Bayly, Megan; Brennan, Emily; Biener, Lois; Wakefield, Melanie

2018-01-01

Emotive anti-tobacco advertisements can increase quitting. Discrete emotion theories suggest evoking fear may be more effective than sadness; less research has focused on hope. A weekly cross-sectional survey of smokers and recent quitters (N = 7683) measured past-month quit attempts. The main predictor was level of exposure to four different types of anti-tobacco advertisements broadcast in the two months prior to quit attempts: advertisements predominantly evoking fear, sadness, hope, or evoking multiple negative emotions (i.e., fear, guilt, and/or sadness). Greater exposure to fear-evoking advertisements (OR = 2.16, p < .01) increased odds of making a quit attempt and showed similar effectiveness among those in lower and higher SES areas. Greater exposure to advertisements evoking multiple negative emotions increased quit attempts (OR = 1.70, p < .01), but interactions indicated this was driven by those in lower SES, but not higher SES areas. Greater exposure to hope-evoking advertisements enhanced effects of fear-evoking advertisements among those in higher SES, but not lower SES areas. Findings suggest to be maximally effective across the whole population avoid messages evoking sadness and use messages eliciting fear. If the aim is to specifically motivate those living in lower SES areas where smoking rates are higher, multiple negative emotion messages, but not hope-evoking messages, may also be effective.

Despite the suggestion to adopt a balanced approach between detachment and involvement, the nurse-patient relationship is always embedded with emotional conflicts. To collect data on how nurses manage the emotional support to patients. The study adopted the theoretical perspective of the emotional work. Fifty-three nurses completed a questionnaire investigating everyday "emotional accidents." The data were analyzed considering the strategies employed to address and resolve them. All nurses exert an emotional work to try to outcome the dissonance between subjective emotions and emotional rules required by the professional role. There are three strategies: normalizing, regressive, transformative. Most of the emotional efforts are aimed at showing emotions in accordance with the role, even if they are dissonant with respect to the subjective feelings (surface acting). Nurses are expected to practice an "emotional neutrality", but their profession continually exposes them to a heavy emotional work that may be at the basis of emotional exhaustion and burnout. Strategies should be adopted to prevent stress and health damages.

Full Text Available Background: Anesthesia is a demanding occupation due to long working hours, sustained vigilance, unpredictability of stressful situation, fear of litigation, competence, and production pressure. Work-related exhaustion can lead to several physical and psychological symptoms and delay decision making. The aim of this study was to evaluate how different work conditions affect personnel exhaustion by studying a sample of anesthesiologists comparing them with ophthalmologists and ancillary hospital staff Methods: One hundred fifty persons divided into three equal groups (50 each were invited to participate in this study. Subjects were asked to answer two self report questionnaires: The Multidimensional Fatigue Inventory (MFI-20 and General Health Questionnaire (GHQ-12 which used to assess work related exhaustion and mental health, respectively. Results: Multidimensional Fatigue Inventory scale (MFI 20 and General Health Questionnaire (GHQ 12 were significantly higher in anesthesiologists than in other groups ( P = 0.001. Different aspects of work-related exhaustion showed that general, physical and mental fatigue were significantly higher in anesthesiologists ( P = 0.002 and 0.001, respectively. Reduced activity and reduced motivation were also higher in anesthesiologists compare to the other groups ( P = 0.005 and 0.001, respectively. Conclusion: Work-related exhaustion under the current study is more obvious among anesthesiologists. Ophthalmologist and ancillary hospital employees felt that they had less stress at their work.

Highlights: • Recycling of waste printed circuit boards is an important issue. • Pyrolysis is an emerging technology for PCB treatment. • Emission factors of VOCs are determined for PCB pyrolysis exhaust. • Iron-Al{sub 2}O{sub 3} catalyst was employed for the exhaust control. -- Abstract: The printed circuit board (PCB) is an important part of electrical and electronic equipment, and its disposal and the recovery of useful materials from waste PCBs (WPCBs) are key issues for waste electrical and electronic equipment. Waste PCB compositions and their pyrolysis characteristics were analyzed in this study. In addition, the volatile organic compound (VOC) exhaust was controlled by an iron-impregnated alumina oxide catalyst. Results indicated that carbon and oxygen were the dominant components (hundreds mg/g) of the raw materials, and other elements such as nitrogen, bromine, and copper were several decades mg/g. Exhaust constituents of CO, H{sub 2}, CH{sub 4}, CO{sub 2}, and NOx, were 60–115, 0.4–4.0, 1.1–10, 30–95, and 0–0.7 mg/g, corresponding to temperatures ranging from 200 to 500 °C. When the pyrolysis temperature was lower than 300 °C, aromatics and paraffins were the major species, contributing 90% of ozone precursor VOCs, and an increase in the pyrolysis temperature corresponded to a decrease in the fraction of aromatic emission factors. Methanol, ethylacetate, acetone, dichloromethane, tetrachloromethane and acrylonitrile were the main species of oxygenated and chlorinated VOCs. The emission factors of some brominated compounds, i.e., bromoform, bromophenol, and dibromophenol, were higher at temperatures over 400 °C. When VOC exhaust was flowed through the bed of Fe-impregnated Al{sub 2}O{sub 3}, the emission of ozone precursor VOCs could be reduced by 70–80%.

Project S-4404, Upgrade Canyon Exhaust Systems, is a $177 million project with the purpose of upgrading the Exhaust Systems for both F and H Canyon Facilities. This upgrade will replace major portions of the F and H-Canyon exhaust systems, downstream of their respective sand filters with higher capacity and more reliable systems. Because of the high cost, DOE requested Program Control ampersand Integration (PC ampersand I) to examine specific deletions to the project. PC ampersand I requested Nuclear Processes Safety Research (NPSR) to perform an analysis to compare failure rates for the existing F ampersand H Canyon exhaust systems with the proposed exhaust system and specific proposed exhaust system alternatives. The objective of this work was to perform an analysis and compare failure rates for the existing F ampersand H Canyon exhaust systems with the proposed project exhaust system and proposed project alternatives. Based on fault tree analysis, two conclusions are made. First, D ampersand D activities can be eliminated from the project with no significant decrease to exhaust system safety. Deletion of D ampersand D activities would result in a cost savings of $29 million. Second, deletion of DOE Order 6430.1A requirements regarding DBAs would decrease exhaust system safety by a factor of 12

HPLC analysis of aldehydes in automobile exhaust gas: Comparison of exhaust odor and irritation in different types of gasoline and diesel engines

International Nuclear Information System (INIS)

Roy, Murari Mohon

2008-01-01

This study investigated high performance liquid chromatography (HPLC) to identify and measure aldehydes from automobile exhaust gas. Four aldehydes: formaldehyde (HCHO), acetaldehyde (CH 3 CHO), acrolein (H 2 C=CHCHO) and propionaldehyde (CH 3 CH 2 CHO) and one ketone, acetone (CH 3 ) 2 CO are separated. The other higher aldehydes in exhaust gas are very small and cannot be separated. A new method of gas sampling, hereafter called bag sampling in HPLC is introduced instead of the trapping gas sampling method. The superiority of the bag sampling method is its transient gas checking capability. In the second part of this study, HPLC results are applied to compare exhaust odor and irritation of exhaust gases in different types of gasoline and diesel engines. Exhaust odor, irritation and aldehydes are found worst in direct injection (DI) diesel engines and best in some good multi-point injection (MPI) gasoline and direct injection gasoline (DIG) engines. Indirect injection (IDI) diesel engines showed odor, irritation and aldehydes in between the levels of MPI gasoline, DIG and DI diesel engines

Zito, Margherita; Cortese, Claudio G; Colombo, Lara

2016-01-01

In the light of the job demands-resources model, this study aimed to detect the mediating role of flow at work between job demands and job resources on one side, and exhaustion on the other. In a historical period where it is necessary to reduce the abandonment of nursing profession, flow is a useful tool to investigate the factors that can promote work motivation and prevent psychological distress. A cross-sectional study was conducted in a hospital, and 279 nurses completed a questionnaire. Analyses conducted are descriptive statistics, alphas, correlations and a structural equations model that considers the mediating role of flow at work. Findings show both the central role of job resources in determining flow at work, and the mediating role of flow at work in decreasing exhaustion, starting from job resources, and in decreasing the effect of job demands on exhaustion. Moreover, flow at work directly decreases exhaustion. Results show the relevance of containing job demands and provide job resources to promote positive experiences at work. To promote flow at work, organizations should offer specific resources, such as supervisors' support, job autonomy, and psychological support to manage the emotional charge. © 2015 John Wiley & Sons Ltd.

To identify measures that should reduce the incidence of burn injuries resulting from motorcycle exhaust pipes through epidemiological analysis of such injuries. During a 5-year period, 251 persons who suffered burn injuries related to motorcycle exhaust pipes have contacted four major hospitals belonging to the Emergency Department Injury Surveillance System (EDISS) operating since 1996 in Greece. These burn injuries were studied in relation to person, environment and vehicle characteristics. The estimated countrywide incidence of burns from motorcycle exhaust pipes was 17 per 100,000 person-years (208 per 100,000 motorcycle-years). The incidence was two times higher for children than for older persons and among the latter it was 60% higher among females than among males. Most of burn injuries (70.5%) concerned motorcycle passengers, mainly when getting on or off motorcycle, with peak incidence during summer. The most frequent location of burn wounds was below the knee and particularly the right leg. It was estimated that the risk of motorcycle exhaust pipe burns when wearing shorts could be reduced by 46% through wearing long pants. Among the victims 65.3% experienced second degree burns. Motorcycle exhaust burns could be substantially reduced by systematically wearing long pants, by incorporating in the design of motorcycles external thermo resistant shields with adequate distance to the exhaust pipe, and by avoiding riding with children on motorcycles.

The tendency for emotions to be predictable over time, labelled emotional inertia, has been linked to low well-being and is thought to reflect impaired emotion regulation. However, almost no studies have examined how emotion regulation relates to emotional inertia. We examined the effects of cognitive reappraisal and expressive suppression on the inertia of behavioural, subjective and physiological measures of emotion. In Study 1 (N = 111), trait suppression was associated with higher inertia of negative behaviours. We replicated this finding experimentally in Study 2 (N = 186). Furthermore, in Study 2, instructed suppressors and reappraisers both showed higher inertia of positive behaviours, and reappraisers displayed higher inertia of heart rate. Neither suppression nor reappraisal were associated with the inertia of subjective feelings in either study. Thus, the effects of suppression and reappraisal on the temporal dynamics of emotions depend on the valence and emotional response component in question.

Current research on emotion shows an increasing interest in the neuronal correlates of emotion regulation (ER). While previous research on ER has focused on gray matter correlates, this study represents the first exploratory study on white matter integrity and brain networks of ER. Responding to the gap between cognitive and affective approaches of ER, pertaining to some of the daily emotional stressors, the present study investigates a complementary experiential approach such as 'Emotional approach' or the tendency to affectively acknowledge, understand and express emotional experience (cf. Stanton et al., 2000). Diffusion tensor magnetic resonance imaging (DTI-MRI) measures of fractional anisotropy (FA) and mean diffusivity (MD) evaluated dispositional ER in a group of 21 women with (1) a 'high emotional approach' (HEA) (N = 11) and (2) a 'low emotional approach' (LEA) (N= 10). HEA exhibited more FA of the cingulum supporting emotion processing and regulation, whereas LEA showed a higher FA in the right corticospinal tracts supporting automatic action tendencies and, together with a higher FA in the superior longitudinal fasciculus (SLF), cognitive control tasks and monitoring of emotion. LEA also correlated with a significant increase in MD in the body (p. = 0.05) and in the splenium of the corpus callosum (CC). A higher FA in the inferior longitudinal fasciculus (IFL) may indicate higher visual- affective integration within emotion processing, whereas more MD in the body and splenium of the CC may decrease the interhemispheric integration of emotional information within emotion processing and regulation.

How rude! Emotional labor as a mediator between customer incivility and employee outcomes.

Science.gov (United States)

Sliter, Michael; Jex, Steve; Wolford, Katherine; McInnerney, Joanne

2010-10-01

Because of the large number of people employed in service occupations, customer incivility has become an increasingly prevalent and important workplace stressor. Unfortunately, relatively little research has examined the effects of customer incivility; of the research that does exist, virtually all of it has focused solely on employee mental health outcomes. The present study was designed to replicate previous research linking customer incivility to the emotional exhaustion dimension of burnout and to expand on previous research by examining the effects of customer incivility on customer service quality. In addition, two models were proposed and tested in which emotional labor mediated the relationship between customer incivility and outcomes. Data from 120 bank tellers revealed that customer incivility was positively related to emotional exhaustion and negatively related to customer service performance. In addition, both proposed models were supported. Theoretical and practical implications of the findings and future directions are discussed. © 2010 APA, all rights reserved.

You spin me right round: Cross-relationship variability in interpersonal emotion regulation

2012-10-01

Full Text Available Individuals use a range of interpersonal emotion regulation strategies to influence the feelings of others, e.g., friends, family members, romantic partners, work colleagues. But little is known about whether people vary their strategy use across these different relational contexts. We characterize and measure this variability as ‘spin’, i.e., the extent of dispersion in a person’s interpersonal emotion regulation strategy use across different relationships, and focus on two key questions. First, is spin adaptive or maladaptive with regard to personal well-being and relationship quality? Second, do personality traits that are considered important for interpersonal functioning (i.e., empathy, attachment style predict spin? The data used in this study is drawn from a large online survey. A key contribution of this study is to reveal that people who varied the type of strategies they used across relationships (i.e., those with high spin had lower positive mood, higher emotional exhaustion and less close relationships. A further key contribution is to show that spin was associated with low empathic concern and perspective taking and high anxious attachment style. High variability in interpersonal emotion regulation strategies across relationships therefore appears to be maladaptive both personally and socially.

Nurses’ burnout and counterproductive work behavior in a Nigerian sample: The moderating role of emotional intelligence

Directory of Open Access Journals (Sweden)

Leonard I. Ugwu

Full Text Available This study examined the moderating role of EI in the relationship between burnout and CWB among 401 nurses drawn from various hospitals within South-eastern Nigeria. Three instruments were used for the collection of data, namely: Counterproductive Work Behaviour Checklist, Maslach Burnout Inventory, and Brief Emotional Intelligence scale. Moderated multiple regression results showed that emotional exhaustion, depersonalization, and personal accomplishment, positively predicted CWB. In addition, EI significantly and negatively predicted CWB. Results also showed that EI moderated the positive relationship between emotional exhaustion and CWB and between depersonalization and CWB such that the positive relationship between these two dimensions of burnout and CWB was stronger for nurses with low EI compared to those with high EI. The implications of the findings and limitations of the study were discussed. Keywords: Nurses, Burnout, Counterproductive work behaviour, Emotional intelligence

We distinguish two evaluative systems which evoke automatic and reflective emotions. Automatic emotions are direct reactions to stimuli whereas reflective emotions are always based on verbalized (and often abstract) criteria of evaluation. We conducted an electroencephalography (EEG) study in which 25 women were required to read and respond to emotional words which engaged either the automatic or reflective system. Stimulus words were emotional (positive or negative) and neutral. We found an effect of valence on an early response with dipolar fronto-occipital topography; positive words evoked a higher amplitude response than negative words. We also found that topographically specific differences in the amplitude of the late positive complex were related to the system involved in processing. Emotional stimuli engaging the automatic system were associated with significantly higher amplitudes in the left-parietal region; the response to neutral words was similar regardless of the system engaged. A different pattern of effects was observed in the central region, neutral stimuli engaging the reflective system evoked a higher amplitudes response whereas there was no system effect for emotional stimuli. These differences could not be reduced to effects of differences between the arousing properties and concreteness of the words used as stimuli.

In this study observed the role of hydrogen bonding to the composition of exhaust emissions which is produced hydrous ethanol fuel (95.5% v). Testing is done by using single cylinder four stroke motor engine. The composition of exhaust gas emissions is tested using exhaust gas analyzer on lean and stoichiometry mixer. The exhaust emissions produced by anhydrous ethanol were also tested. The composition of emissions produced by that two fuels is compared. The results showed CO emissions levels produced by hydrous ethanol are slightly higher than anhydrous ethanol in stoichiometric mixtures. But the composition of CO hydrous ethanol emissions is lower in the lean mix. If lean the mixer the different in the composition of emissions is increasing. On hydrous ethanol emission CO2 content little bit lower on the stoichiometric mixer and higher on the lean mixture. Exhaust emissions of ethanol fuel also produce O2. O2 hydrous ethanol emissions is higher than anhydrous ethanol fuel.

Quinones, C; Rodríguez-Carvajal, R; Griffiths, MD

2017-01-01

Studies suggest that suppressing emotions required by occupational roles (i.e., surface acting [SA]) can lead to employees’ emotional exhaustion. In contrast, trying to experience the emotions required by the role (i.e., deep acting [DA]) appears to be a less harmful strategy for the employee. However, problems with 1 of the mainstream measures of DA call for a reexamination of the construct’s operationalization and a clarification of its consequences. Furthermore, an integrated model explain...

Drawing on the conservation of resources theory, the relations between abusive supervision and emotional exhaustion and intent to leave were examined, as well as the gender differences in these relations. Moreover, the moderating effect of self-esteem was tested in an integrated model stipulating that the gender-moderating effect was mediated by the abusive supervision × self-esteem interaction. Data were collected from 264 employees (111 men; M age = 32.0 years; M tenure = 9.2 years). Results of regression analyses indicated that abusive supervision was positively correlated to emotional exhaustion and intent to leave. Women reported higher emotional exhaustion and intent to leave than men. The relations of interest were stronger among employees with higher self-esteem (emotional exhaustion: β = 0.44; intent to leave: β = 0.53). The interaction of abusive supervision × self-esteem mediated the gender-moderating effect. Women's stronger responses to abusive supervision may be related to their higher self-esteem, possibly because of the importance of employment to Chinese women. © The Author(s) 2016.

Emotional memory consolidation under lower versus higher stress conditions

Directory of Open Access Journals (Sweden)

Inna eKogan

2010-12-01

Full Text Available An exposure to stress can enhance memory for emotionally arousing experiences. The phenomenon is suggested to be amygdala-dependent and in accordance with that view the amygdala was found to modulate mnemonic processes in other brain regions. Previously, we illustrated increased amygdala activation and reduced activation of CA1 following spatial learning under high versus low emotionality conditions. When spatial learning was followed by reversal training interference, impaired retention was detected only under high emotionality conditions. Here we further evaluate the potential implications of the difference in the level of amygdala activation on the quality of the memory formed under these stress conditions. We attempted to affect spatial memory consolidation under low or high stress conditions by either introducing a foot shock interference following massed training in the water maze; by manipulating the threshold for acquisition employing either brief (3 trials or full (12 trials training sessions; or by employing a spaced training (over three days rather than massed training protocol. The current findings reveal that under heightened emotionality, the process of consolidation seems to become less effective and more vulnerable to interference; however, when memory consolidation is not interrupted, retention is improved. These differential effects might underlie the complex interactions of stress, and, particularly, of traumatic stress with memory formation processes.

2014-10-01

The current and projected nurse faculty shortage threatens the capacity to educate sufficient numbers of nurses for meeting demand. As part of an initiative to foster strategies for expanding educational capacity, a survey of a nationally representative sample of 3,120 full-time nurse faculty members in 269 schools and programs that offered at least one prelicensure degree program was conducted. Nearly 4 of 10 participants reported high levels of emotional exhaustion, and one third expressed an intent to leave academic nursing within 5 years. Major contributors to burnout were dissatisfaction with workload and perceived inflexibility to balance work and family life. Intent to leave was explained not only by age but by several potentially modifiable aspects of work, including dissatisfaction with workload, salary, and availability of teaching support. Preparing sufficient numbers of nurses to meet future health needs will require addressing those aspects of work-life that undermine faculty teaching capacity. Copyright 2014, SLACK Incorporated.

Full Text Available Complaints of fatigue and physical exhaustion are frequently seen in the acute medical setting, especially amongst athletes, army recruits and persons involved in strenuous and exertional physical activities. Stress-induced exhaustion, on the other hand, is less often seen, but can present with very similar symptoms to physical exhaustion. Recently, three patients were seen at the Department of Emergency Medicine, presenting with exhaustion from prolonged involvement in gambling activities. The cases serve to highlight some of the physical consequences of prolonged gambling.

A nuclear microprobe with high spatial resolution and high analytical sensitivity was applied to analyze trace elements, especially lead, in vehicle exhaust of Shanghai city. The result shows that the chemical composition and its corresponding x-ray relative intensity are different among different vehicle exhausts. There are many kinds of metal elements in particles of vehicle exhaust, most are harmful to people, such as Ti, Cr, Mn, Pb, etc. The authors found that the lead concentration was 6820 μg/g and the bromine concentration was 5300 μg/g in the exhaust from Santana using leaded gasoline (SULG), which is higher than any other kinds of vehicle exhausts. The authors have also detected the minimum lead in the particles of unleaded gasoline and its content varies from one to another. Its mean concentration was 450 μg/g and the highest reached 6210 μg/g. The unleaded gasoline's Pb existed in the whole particle while the leaded gasoline's enriched in the surface of the particle and was more harmful to the human beings

Full Text Available Purpose of the present study was to extrapolate intricate relationships between autonomic indices of emotionality in predicting changes in transient as well as dispositional emotionality. Performance excellence in sports and games, particularly in soccer has been referred to as resultant of mental toughness or more specifically the aspect of emotional flexibility and hardiness of the athlete. One hundred thirty five high-achiever young-adult male competitive soccer players, who were residents of Kota Bharu region volunteered as participants. All of them were subjected to evaluation of inner psychobiological status (decomposed indices of phasic skin conductance activity – viz. orienting recovery time; rise time and skin conductance adaptation levels; assessment of projective analyses of unconscious core of emotionality (employing Rorschach Ink-Blot Test in the form of evaluation indices of impulsivity, irritability, integrity. Results however revealed corroborative relationships between psychobiological autonomic indices in predicting differential aspects of inner core emotionality. Multiple linear regression analyses were done to identify differential possibilities of direct, inverse, moderating and supportive relationships between decomposition indices of autonomic orienting activity related to cognitive-affective and affective-motivational aspects of sports behaviour. Analyses of autonomic activation and arousal modulation and various indices habituation paradigm indices were found as significant predictors of changes in dispositional emotional constellation observed in the athletes. Orienting latency was observed as the most significant contributor in influencing recovery from autonomic arousal (orienting recovery in predicting changes in emotional hardiness as well as in flexibility.

Forgiveness from Emotion Fit: Emotional Frame, Consumer Emotion, and Feeling-Right in Consumer Decision to Forgive

Ran, Yaxuan; Wei, Haiying; Li, Qing

2016-01-01

Three studies examine an emotion fit effect in the crisis communication, namely, the interaction between emotional frames of guilt and shame and consumer emotions of anger and fear on consumer forgiveness. Guilt-framing communication results in higher forgiveness than shame-framing for angry consumers, whereas shame-framing communication results in higher forgiveness than guilt-framing for fearful consumers. These effects are driven by consumers’ accessible regulatory foci associated with anger/fear and guilt/shame. Specifically, feelings of anger activate a promotion focus that is represented by guilt frames, while feelings of fear activate a prevention focus that is enacted by shame frames. Compared with emotion non-fit (i.e., anger to shame and fear to guilt), emotion fit (i.e., anger to guilt and fear to shame) facilitates greater feeling-right and consumer forgiveness. The findings offer novel insights for extant literature on emotion, crisis communication, and regulatory focus theory, as well as practical suggestions regarding the emotional frames. PMID:27895612

Two studies on the effects of small exhaust fans on indoor air quality: Field study of exhaust fans for mitigating indoor air quality problems; Indoor air quality, exhaust fan mitigation

International Nuclear Information System (INIS)

1987-07-01

Overall, the findings show that exhaust fans basically provide small amounts of ventilation compensation. By monitoring the common indoor air pollutants (radon, formaldehyde, carbon monoxide, nitrogen dioxide, and water vapor), it was found that the quality of the indoor air was not adversely affected by the use of exhaust fans. Nor did their use provide any measurable or significant benefits since no improvement in air quality was ascertained. While exhaust fans of this small size did not increase radon, which is the contaminant of most concern, the researchers caution that operation of a larger fan or installation in a very tight home could result in higher levels because depressurization is greater. The daily energy consumption for use of these appliances during the heating season was calculated to be 1.5 kilowatt hours or approximately 3% of the energy consumption in the study homes. The information collected in this collaborative field study indicates that the use of these particular ventilation systems has no significant effect on indoor air quality

Österberg, Kai; Skogsliden, Sofia; Karlson, Björn

2014-01-01

The aim was to assess long-term cognitive performance after substantial recovery from work-stress-related exhaustion, in relation to subjective cognitive complaints and return to active work. In total, 54 patients previously diagnosed with work-stress-related exhaustion participated in a neuropsychological examination ∼2 years after initial sick leave. Most participants were substantially recovered at follow-up, with only 13% still meeting the criteria for exhaustion disorder suggested by the Swedish National Board of Health and Welfare. When participants' scores on 14 neuropsychological tests were compared to a matched group of 50 controls, the former patient group showed lower performance mainly on attention tests of the reaction time type, but also slightly lower scores on visuo-spatial constructional ability. However, the former patient group performed better than controls on two memory tests and, in part, on a test of simultaneous capacity. Self-ratings of everyday cognitive problems remained significantly higher in the former patient group than among controls, but the extent of self-rated cognitive problems was generally unrelated to performance on the neuropsychological tests. No relationship between performance on these tests and the extent of work resumption was observed. In summary, persons with previous work-stress-related exhaustion showed persistent signs of a minor attention deficit, despite considerable general recovery and return to work.

Daily Use of Energy Management Strategies and Occupational Well-being: The Moderating Role of Job Demands

Stacey L. Parker

2017-08-01

Full Text Available We examine the relationships among employees’ use of energy management strategies and two occupational well-being outcomes: job satisfaction and emotional exhaustion. Based on conservation of resources theory, it was hypothesized that employees with high job demands would benefit more from using energy management strategies (i.e., including prosocial, organizing, and meaning-related strategies, compared to employees with low job demands. We tested this proposition using a quantitative diary study. Fifty-four employees provided data twice daily across one work week (on average, 7 daily entries. Supporting the hypotheses, prosocial energy management was positively related to job satisfaction. Moreover, employees with high job demands were less emotionally exhausted when using prosocial strategies. Contrary to predictions, when using organizing strategies, employees with low job demands had higher job satisfaction and lower emotional exhaustion. Under high job demands, greater use of organizing strategies was associated with lower job satisfaction and higher emotional exhaustion. Finally, use of meaning-related strategies was associated with higher emotional exhaustion when job demands were low. With this research, we position energy management as part of a resource investment process aimed at maintaining and improving occupational well-being. Our findings show that this resource investment will be more or less effective depending on the type of strategy used and the existing drain on resources (i.e., job demands. This is the first study to examine momentary effects of distinct types of work-related energy management strategies on occupational well-being.

The moderating role of cognitive control deficits in the link from emotional dissonance to burnout symptoms and absenteeism.

Diestel, Stefan; Schmidt, Klaus-Helmut

2011-07-01

The present study examines whether cognitive control deficits (CCDs) as a personal vulnerability factor amplify the relationship between emotional dissonance (ED; perceived discrepancy between felt and expressed emotions) and burnout symptoms (emotional exhaustion and depersonalization) as well as absenteeism. CCDs refer to daily failures and impairments of attention regulation, impulse control, and memory. The prediction of the moderator effect of CCDs draws on the argument that portraying emotions which are not genuinely felt is a form of self-regulation taxing and depleting a limited resource capacity. Interindividual differences in the resource capacity are reflected by the measure of CCDs. Drawing on two German samples (one cross-sectional and one longitudinal sample; NTOTAL = 645) of service employees, the present study analyzed interactive effects of ED and CCDs on exhaustion, depersonalization, and two indicators of absenteeism. As was hypothesized, latent moderated structural equation modeling revealed that the adverse impacts of ED on both burnout symptoms and absence behavior were amplified as a function of CCDs. Theoretical and practical implications of the present results will be discussed.

Research on emotional labour in health care work has not yet revealed under what conditions emotional job demands have an impact on employee health and well-being. There is a need for more theory to unveil the black box of emotional labour processes. To test the moderating role of matching (i.e. emotional) and non-matching (i.e. cognitive) job resources in the relation between emotional job demands and employee health/well-being (i.e. emotional exhaustion, employee creativity, and work motivation). A cross-sectional survey with anonymous questionnaires was conducted. A large organization for residential elderly care with eight locations in an urban area in the Netherlands. Questionnaires were distributed to 1259 health care workers, of which 826 people returned the questionnaire (66% response rate). In addition to descriptive statistics, multivariate multiple regression analysis (LISREL 8.54) with cross-validation was conducted. Findings showed that emotional job resources moderated the relation between emotional job demands and health/well-being outcomes. Firstly, emotional job resources were able to moderate the relation between emotional job demands and emotional exhaustion. Secondly, both emotional job resources and, to a lesser extent, cognitive job resources were able to moderate the relation between emotional job demands and positive well-being outcomes (i.e. employee creativity and work motivation). Finally, cross-validation showed that parameter estimates did not vary across subsamples. Job resources could compensate for resources lost through meeting the requirements of emotional job demands, thereby reducing stress-reactions and increasing well-being. Providing health care workers with more, preferably matching, job resources could make emotional job demands less stressful, and even stimulating and challenging. Future longitudinal studies should investigate the interplay of emotional job demands and (matching) job resources more profoundly.

Noise Radiation Of A Strongly Pulsating Tailpipe Exhaust

Peizi, Li; Genhua, Dai; Zhichi, Zhu

1993-11-01

The method of characteristics is used to solve the problem of the propagation of a strongly pulsating flow in an exhaust system tailpipe. For a strongly pulsating exhaust, the flow may shock at the pipe's open end at some point in a pulsating where the flow pressure exceeds its critical value. The method fails if one insists on setting the flow pressure equal to the atmospheric pressure as the pipe end boundary condition. To solve the problem, we set the Mach number equal to 1 as the boundary condition when the flow pressure exceeds its critical value. For a strongly pulsating flow, the fluctuations of flow variables may be much higher than their respective time averages. Therefore, the acoustic radiation method would fail in the computation of the noise radiation from the pipe's open end. We simulate the exhaust flow out of the open end as a simple sound source to compute the noise radiation, which has been successfully applied in reference [1]. The simple sound source strength is proportional to the volume acceleration of exhaust gas. Also computed is the noise radiation from the turbulence of the exhaust flow, as was done in reference [1]. Noise from a reciprocating valve simulator has been treated in detail. The radiation efficiency is very low for the pressure range considered and is about 10 -5. The radiation efficiency coefficient increases with the square of the frequency. Computation of the pipe length dependence of the noise radiation and mass flux allows us to design a suitable length for an aerodynamic noise generator or a reciprocating internal combustion engine. For the former, powerful noise radiation is preferable. For the latter, maximum mass flux is desired because a freer exhaust is preferable.

Full Text Available The article deals with the problem of psychological health of the faculty of the university, the causes and factors of the syndrome of emotional burnout of teachers are systematized. The signs characterizing the emergence of the syndrome of emotional burnout are revealed. Particular attention is paid to the methodology and results of the empirical study of predisposition to the syndrome. The presence of certain personal characteristics, predisposing to the formation and development of emotional burnout, was traced in the teachers of the university. It was revealed that the syndrome affects not only teachers, but also indirectly on the students of the educational institution. Dependence of the degree of severity of emotional burnout syndrome on age and work experience of the teacher is noted. It is determined that to confront the burnout the teaching staff of the university should possess, with the appropriate resources, internal and external variables that contribute to psychological stability in stressful situations.

Validation of Karolinska Exhaustion Scale: psychometric properties of a measure of exhaustion syndrome.

Saboonchi, Fredrik; Perski, Aleksander; Grossi, Giorgio

2013-12-01

The syndrome of exhaustion is currently a medical diagnosis in Sweden. The description of the syndrome largely corresponds to the suggested core component of burnout, that is exhaustion. Karolinska Exhaustion Scale (KES) has been constructed to provide specific assessment of exhaustion in clinical and research settings. The purpose of the present study was to examine the psychometric properties of this scale in its original and revised versions by examining the factorial structure and measures of convergent and discriminant validity. Data gathered from two independent samples (n1 = 358 & n2 = 403) consisting of patients diagnosed with 'reaction to severe stress, and adjustment disorder' were subjected to confirmatory factor analysis. The study's instruments were Karolinska Exhaustion Scale and Shirom Melam Burnout Measure. Correlation analyses were employed to follow up the established factorial structure of the scale. The study was ethically approved by Karolinska Institute regional ethic committee. The findings demonstrated adequate fit of the data to the measurement model provided by the revised version of KES Limitations: The main limitation of the present study is the lack of a gold standard of exhaustion for direct comparison with KES. (KES-26) and partially supported convergent validity and discriminant validity of the scale. The demonstrated psychometric properties of KES-26 indicate sound construct validity for this scale encouraging use of this scale in assessment of exhaustion. The factorial structure of KES-26 may also be used to provide information concerning possible different clinical profiles. © 2012 The Authors Scandinavian Journal of Caring Sciences © 2012 Nordic College of Caring Science.

Gas turbine exhaust system silencing design

International Nuclear Information System (INIS)

Ozgur, D.

1991-01-01

Gas turbines are the preferred prime mover in many applications because of their high efficiency, fuel flexibility, and low environmental impact. A typical mid-size machine might have a power rating of 80 MW, a flow of about 1000 kg/hr, and an exhaust temperature of over 500C. The most powerful single source of noise is generally the exhaust, which may generate over a kilowatt of acoustic energy. This paper reports that there are two important ways in which exhaust systems can radiate noise. The first is through the discharge of the exhaust duct, with the exhaust gas. Because of the large quantity of hot gas, the duct exit is always oriented vertically; it may be fairly high in the air in order to promote dispersion of the exhaust plume. This source is almost always attenuated by means of a silencer located somewhere in the ductwork. The second source of noise is often called breakout; it is the radiation of exhaust noise through the walls of the ducting. Breakout is most important for those sections of the exhaust duct which lie upstream of the silencer, where sound levels inside the ducting are highest. Both exhaust duct exit noise and breakout noise can be calculated from the sound power level of the gas turbine exhaust and the sound transmission loss (TL) of the silencer and ducting

Experimental Evaluation of Installed Cooking Exhaust Fan Performance

Energy Technology Data Exchange (ETDEWEB)

Singer, Brett C.; Delp, William W.; Apte, Michael G.

2010-11-01

The installed performance of cooking exhaust fans was evaluated through residential field experiments conducted on a sample of 15 devices varying in design and other characteristics. The sample included two rear downdraft systems, two under-cabinet microwave over range (MOR) units, three different installations of an under-cabinet model with grease screens across the bottom and no capture hood, two devices with grease screens covering the bottom of a large capture hood (one under-cabinet, one wall-mount chimney), four under-cabinet open hoods, and two open hoods with chimney mounts over islands. Performance assessment included measurement of airflow and sound levels across fan settings and experiments to quantify the contemporaneous capture efficiency for the exhaust generated by natural gas cooking burners.Capture efficiency is defined as the fraction of generated pollutants that are removed through the exhaust and thus not available for inhalation of household occupants. Capture efficiency (CE) was assessed for various configurations of burner use (e.g., single front, single back, combination of one front and one back, oven) and fan speed setting. Measured airflow rates were substantially lower than the levels noted in product literature for many of the units. This shortfall was observed for several units costing in excess of $1000. Capture efficiency varied widely (from<5percent to roughly 100percent) across devices and across conditions for some devices. As expected, higher capture efficiencies were achieved with higher fan settings and the associated higher air flow rates. In most cases, capture efficiencies were substantially higher for rear burners than for front burners. The best and most consistent performance was observed for open hoods that covered all cooktop burners and operated at higher airflow rates. The lowest capture efficiencies were measured when a front burner was used with a rear backdraft system or with lowest fan setting for above the range

Quality of motivation, self-control competencies, as well as past performance experience influence sport participation outcomes in developing athletes. Studies have shown that junior athletes high in self-determined motivation are less prone to experience burnout, while self-control competencies help developing athletes to be conscious and deliberate in their self-regulatory efforts toward elite sport performances and avoid negative sport participation outcomes. Combining the self-determination theory framework and psychosocial theories of self-regulation, the aim of this cross-sectional study was to examine how various types of motivation and self-control competencies together are associated with the development of burnout symptoms in junior athletes. High-level Norwegian winter-sport athletes from elite sport academies ( N = 199; female n = 72; 16-20 years of age) consented to participate. Associations between six types of motivational regulation, self-control, and indices of exhaustion were investigated. We hypothesized that athletes' self-control competencies are important to operate successfully, and influenced by different types of motivation, they are expected to help athletes avoid negative sport participation outcomes such as emotional and physical exhaustion. Structural equation modeling analyses were conducted to analyze these relationships, and results revealed some multifaceted associations. When identifying antecedents of sport participation exhaustion and burnout, there is a need to go beyond the unique framework of motivation theories, and explore what cognitive competencies ensure fulfillment of motivation desires. In the current study, differences in junior athletes' quality of motivation influenced self-control competencies when predicting exhaustion. Interestingly, young athletes driven by self-determined (intrinsic, integrated, and identified), and controlled (introjected and amotivation) regulations in association with self-control offered the

Employees with low levels of work-related self-efficacy may stand to benefit more from a worksite stress management training (SMT) intervention. However, this low work-related self-efficacy/enhanced SMT benefits effect may be conditional on employees also having high levels of intrinsic work motivation. In the present study, we examined this proposition by testing three-way, or higher order, interaction effects. One hundred and fifty-three U.K. government employees were randomly assigned to a SMT intervention group (n = 68), or to a waiting list control group (n = 85). The SMT group received three half-day training sessions spread over two and a half months. Findings indicated that there were significant overall reductions in psychological strain, emotional exhaustion and depersonalization in the SMT group, in comparison to the control group. Furthermore, there were significant higher order Group (SMT vs. control) × Time 1 Work-Related Self-Efficacy × Time 1 Intrinsic Work Motivation interactions, such that reductions in emotional exhaustion and depersonalization at certain time points were experienced only by those who had low baseline levels of work-related self-efficacy and high baseline levels of intrinsic work motivation. Implications for work-related self-efficacy theory and research and SMT research and practice are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Athletic training education program directors (ATEPDs) often manage their time among students, program administration, and patient care. To assess the level of burnout in ATEPDs and to determine the relationship between burnout and various demographics of ATEPDs. Cross-sectional study. Public and private colleges and universities nationwide. Two hundred forty-nine ATEPDs of undergraduate athletic training education programs accredited by the Commission on Accreditation of Athletic Training Education. We administered the Maslach Burnout Inventory (MBI) to all participants. The MBI consisted of 21 items assessing 3 characteristics of burnout: emotional exhaustion, depersonalization, and personal accomplishment. Another component of the survey requested demographic information about the ATEPDs. We used univariate, multivariate, and factorial analyses of variance with the alpha level set a priori at .05. We also calculated Pearson product moment correlation coefficients. Women had greater emotional exhaustion than men (20.67 +/- 9.43 and 16.47 +/- 9.64, respectively) (P = .001). The difference between tenure-status groups for emotional exhaustion was significant (P = .014), with tenure-track ATEPDs scoring higher on emotional exhaustion than tenured ATEPDs. Pearson product moment correlation coefficients revealed a weak negative relationship among emotional exhaustion and age (r = -0.263, P depersonalization (r = -0.171, P = .007). There was a weak positive relationship between years at current job and personal accomplishment (r = 0.197, P = .002). We found that ATEPDs experienced a moderate form of emotional exhaustion burnout and low depersonalization and personal accomplishment burnout, with women experiencing greater emotional exhaustion than males. Additionally, ATEPDs in tenure-track positions experienced greater emotional exhaustion than tenured ATEPDs. The ATEPDs need to obtain healthy coping strategies early within their directorships to manage components

Full Text Available The potent anti-inflammatory activities and tissue-protective effects of freshwater clams (Corbicula fluminea have been well reported. The aim of this study was to determine the effects of freshwater clam extract (FCE supplementation on time to exhaustion, muscle damage, pro- and anti-inflammatory cytokines, and liver injury in rats after exhaustive exercise. Thirty-two rats were divided into four groups: sedentary control (SC; SC group with FCE supplementation (SC+FCE; exhaustive exercise (E; and E group with FCE supplementation (E+FCE. The SC+FCE and E+FCE groups were treated with gavage administration of 20 mg/kg for seven consecutive days. Blood samples were collected for the evaluation of biochemical parameters. The cytokine levels of TNF-α and IL-10 were also examined. Twenty-four hours after exhaustive exercise, the rat livers were removed for H & E staining. The FCE supplementation could extend the time to exhaustion in exercised rats. The levels of CPK, LDH, AST, ALT, lactate, TNF-α and H & E stains of the liver injury were significantly decreased in the E+FCE group, but the blood glucose and IL-10 were significantly higher in comparison with the E group. This study suggests that FCE supplementation may improve endurance performance and reduce exercise-induced muscle damage, inflammatory stress and liver injury.

Sepsis is a disease that affects primarily the aged. Although mortality is higher in both older septic patients and aged septic mice, the mechanisms underlying decreased survival in older hosts are incompletely understood. New work by Inoue and colleagues demonstrates persistent inflammation and T-cell exhaustion in older septic patients and aged septic mice. The clinical significance of these findings is manifested not only in increased mortality but also in a marked difference in secondary infections in older patients as long as a month following ICU admission.

Positive emotion impedes emotional but not cognitive conflict processing.

Cognitive control enables successful goal-directed behavior by resolving a conflict between opposing action tendencies, while emotional control arises as a consequence of emotional conflict processing such as in irony. While negative emotion facilitates both cognitive and emotional conflict processing, it is unclear how emotional conflict processing is affected by positive emotion (e.g., humor). In 2 EEG experiments, we investigated the role of positive audiovisual target stimuli in cognitive and emotional conflict processing. Participants categorized either spoken vowels (cognitive task) or their emotional valence (emotional task) and ignored the visual stimulus dimension. Behaviorally, a positive target showed no influence on cognitive conflict processing, but impeded emotional conflict processing. In the emotional task, response time conflict costs were higher for positive than for neutral targets. In the EEG, we observed an interaction of emotion by congruence in the P200 and N200 ERP components in emotional but not in cognitive conflict processing. In the emotional conflict task, the P200 and N200 conflict effect was larger for emotional than neutral targets. Thus, our results show that emotion affects conflict processing differently as a function of conflict type and emotional valence. This suggests that there are conflict- and valence-specific mechanisms modulating executive control.

Chemical laser exhaust pipe design research

In order to weaken the chemical laser exhaust gas influence of the optical transmission, a vent pipe is advised to emissions gas to the outside of the optical transmission area. Based on a variety of exhaust pipe design, a flow field characteristic of the pipe is carried out by numerical simulation and analysis in detail. The research results show that for uniform deflating exhaust pipe, although the pipeline structure is cyclical and convenient for engineering implementation, but there is a phenomenon of air reflows at the pipeline entrance slit which can be deduced from the numerical simulation results. So, this type of pipeline structure does not guarantee seal. For the design scheme of putting the pipeline contract part at the end of the exhaust pipe, or using the method of local area or tail contraction, numerical simulation results show that backflow phenomenon still exists at the pipeline entrance slit. Preliminary analysis indicates that the contraction of pipe would result in higher static pressure near the wall for the low speed flow field, so as to produce counter pressure gradient at the entrance slit. In order to eliminate backflow phenomenon at the pipe entrance slit, concerned with the pipeline type of radial size increase gradually along the flow, flow field property in the pipe is analyzed in detail by numerical simulation methods. Numerical simulation results indicate that there is not reflow phenomenon at entrance slit of the dilated duct. However the cold air inhaled in the slit which makes the temperature of the channel wall is lower than the center temperature. Therefore, this kind of pipeline structure can not only prevent the leak of the gas, but also reduce the wall temperature. In addition, compared with the straight pipe connection way, dilated pipe structure also has periodic structure, which can facilitate system integration installation.

When getting angry is smart: emotional preferences and emotional intelligence.

Science.gov (United States)

Ford, Brett Q; Tamir, Maya

2012-08-01

People who prefer to feel useful emotions, even when they are unpleasant to experience, must understand emotions and seek to regulate them in strategic ways. Such people, therefore, may be more emotionally intelligent compared with people who prefer to feel emotions that may not be useful for the context at hand, even if those emotions are pleasant to experience. We tested this hypothesis by measuring emotional intelligence and preferences to feel pleasant and unpleasant emotions in contexts in which they are likely to be useful or not. We found significant positive associations between emotional intelligence and preferences for useful emotions, even when controlling for trait emotional experiences and cognitive intelligence. People who prefer to feel anger when confronting others tend to be higher in emotional intelligence, whereas people who prefer to feel happiness in such contexts tend to be lower in emotional intelligence. Such findings are consistent with the idea that wanting to feel bad may be good at times, and vice versa.

2013-01-01

In this study, the stressor-strain-outcome (SSO) model developed by Koeske and Koeske was adopted to examine the mediating effect of burnout between emotional dissonance and organizational citizenship behavior (OCB). The study involved 264 full-time Chinese school teachers (82 men, 16 women, and 22 individuals whose genders were not specified; mean age = 34.4 years and SD = 8.09 years). Correlation analysis showed that emotional dissonance is positively related to all three burnout dimensions (i.e., emotional exhaustion, depersonalization, and lack of personal accomplishment). Emotional dissonance is also negatively related to OCB toward individuals. Results from structural equation modeling support the SSO model, which states that emotional dissonance first leads to burnout and then to lower OCB. The limitations and implications to the school management, such as provision of emotional regulation training and strengthening of the social network system, were also discussed.

Wellbeing: causes and consequences of emotion regulation in work settings.

2005-10-01

Emotion regulation processes are a crucial aspect of the working role in jobs which require employee-customer interactions: What kinds of regulation processes are activated, with what frequency, and what are their correlates and consequences are important aspects to consider because of their potential implications for the well-being of individuals. To investigate these issues, a set of studies was carried out with Italian workers (N=769) performing service jobs in different sectors. Job-related, socio-demographic, and individual psychological variables were taken into account. The results confirmed the hypothesis that in service job-roles emotional labour (EL) is a component whose negative and positive implications for employees' well-being need to be considered. Emotional labour, embedded in a net of relationships with such job variables as frequency and duration of client-interaction, can result in high psychological costs for service workers. In particular, surface acting regulation was found to have a personal cost, indexed by the burnout dimensions of emotional exhaustion and depersonalization.

The present invention concerns a vacuum exhaust duct used for a thermonuclear device. A cylindrical metal liners is lined with a gap to the inside of a vacuum exhaust duct main body. Bellows are connected to both ends of the metal liners and the end of the bellows is welded to the vacuum exhaust duct main body. Futher, a heater is mounted to the metal liner on the side of the vacuum exhaust duct main body, and the metal liner is heated by the heater to conduct baking for the vacuum exhaust duct main body. Accordingly, since there is no requirement for elevating the temperature of the vacuum exhaust duct upon conducting baking, the vacuum exhaust duct scarcely suffers substantial deformation due to heat expansion. Further, there is also no substantial deformation for the bellows disposed between the outer circumference of the vacuum vessel and a portion of a vacuum exhaust duct, so that the durability of the bellows is greatly improved.

Mapping the emotional landscape: The role of specific emotions in conceptual categorization.

Zhu, Nan; Cai, Yong-hua; Sun, Fa-wei; Yang-yang, Yi-fan

2015-07-01

Although researchers generally subscribe to the opinion that emotions play a critical role in cognition, very few (see Niedenthal, Halberstadt, & Innes-Ker, 1999) have examined the specific interaction between the emotional state of the perceiver and the emotional meaning of stimuli in conceptual categorization - an important aspect of "higher-level" cognition. Niedenthal et al. (1999) advanced a fine-grained theory of emotional response categorization, arguing that emotional states increase the tendency to categorize concepts into a predictable set of emotional response categories characterized by the common, distinct emotional responses elicited by the concepts. Based on the pioneering work of Niedenthal et al., we further argued that (1) the specific emotion experienced by the individual should selectively facilitate the categorization of concepts associated with the same emotion, (2) both in terms of category inclusion and category exclusion, and (3) this facilitation effect should not be contingent on the awareness of the emotional state. In three experiments, participants were induced to experience different emotional states through movies or a facial-feedback manipulation. They judged whether or not a target concept belonged to the same category as the two comparison concepts. Some of the concept triads shared emotional associations, while others didn't. Results showed that emotive participants had a greater tendency than those in a neutral mood to group concepts according to their emotional associations, and to distinguish concepts with different emotional associations. They were also more efficient in categorizing concepts that had specific emotional meaning corresponding to their own emotional state than to other emotional concepts. Furthermore, participants posing a disgust expression without their knowledge showed higher tendency to categorize concepts according to their relevance to disgust. Implications and potential applications of the findings were

The aim of the study was to examine the level of job-related burnout and the level of job satisfaction among residents of pediatrics. A total of 102 residents of pediatrics who were trained in two Ministry of Health teaching and research hospitals and in two university hospitals in Izmir were included in the study. Demographic data (age, sex), lifestyle (living with parents or not, marital status, number of children) and professional characteristics (total time spent in profession, time spent in residency, number of night shifts per month, institution type: teaching hospital/university) were collected. Maslach Burnout Inventory (subscales: emotional exhaustion, desensitization, personal accomplishment) and Minnesota Satisfaction Questionnaire were used. High levels of emotional exhaustion and desensitization, and low levels of personal accomplishment and job satisfaction were found in residents of pediatrics. Low levels of emotional exhaustion in teaching and research hospitals and low levels of desensitization in university hospitals were determined (pjob satisfaction levels and a negative correlation between age and emotional exhaustion levels (pjob satisfaction. Emotional exhaustion is more common in teaching and research hospitals and desensitization is more common in universities. Younger age, lower seniority, and the higher number of work-shift increases the burnout.

Swimming training induces liver mitochondrial adaptations to oxidative stress in rats submitted to repeated exhaustive swimming bouts.

Full Text Available BACKGROUND AND AIMS: Although acute exhaustive exercise is known to increase liver reactive oxygen species (ROS production and aerobic training has shown to improve the antioxidant status in the liver, little is known about mitochondria adaptations to aerobic training. The main objective of this study was to investigate the effects of the aerobic training on oxidative stress markers and antioxidant defense in liver mitochondria both after training and in response to three repeated exhaustive swimming bouts. METHODS: Wistar rats were divided into training (n = 14 and control (n = 14 groups. Training group performed a 6-week swimming training protocol. Subsets of training (n = 7 and control (n = 7 rats performed 3 repeated exhaustive swimming bouts with 72 h rest in between. Oxidative stress biomarkers, antioxidant activity, and mitochondria functionality were assessed. RESULTS: Trained group showed increased reduced glutathione (GSH content and reduced/oxidized (GSH/GSSG ratio, higher superoxide dismutase (MnSOD activity, and decreased lipid peroxidation in liver mitochondria. Aerobic training protected against exhaustive swimming ROS production herein characterized by decreased oxidative stress markers, higher antioxidant defenses, and increases in methyl-tetrazolium reduction and membrane potential. Trained group also presented higher time to exhaustion compared to control group. CONCLUSIONS: Swimming training induced positive adaptations in liver mitochondria of rats. Increased antioxidant defense after training coped well with exercise-produced ROS and liver mitochondria were less affected by exhaustive exercise. Therefore, liver mitochondria also adapt to exercise-induced ROS and may play an important role in exercise performance.

This study assessed the performance of seven new residential cooking exhaust hoods representing common U.S. designs. Laboratory tests were conducted to determine fan curves relating airflow to duct static pressure, sound levels, and exhaust gas capture efficiency for front and back cooktop burners and the oven. Airflow rate sensitivity to duct flow resistance was higher for axial fan devices than for centrifugal fan devices. Pollutant capture efficiency (CE) ranged from 98%, varying across hoods and with airflow and burner position for each hood. CE was higher for back burners relative to front burners, presumably because most hoods covered only part of the front burners. Open hoods had higher CE than those with grease screen and metal-covered bottoms. The device with the highest CE--exceeding 80% for oven and front burners--had a large, open hood that covered most of the front burners. The airflow rate for this hood surpassed the industry-recommended level of 118 L·s(-1) (250 cfm) and produced sound levels too high for normal conversation. For hoods meeting the sound and fan efficacy criteria for Energy Star, CE was <30% for front and oven burners.

Exhaust gas recirculation system for an internal combustion engine

Science.gov (United States)

Wu, Ko-Jen

2013-05-21

An exhaust gas recirculation system for an internal combustion engine comprises an exhaust driven turbocharger having a low pressure turbine outlet in fluid communication with an exhaust gas conduit. The turbocharger also includes a low pressure compressor intake and a high pressure compressor outlet in communication with an intake air conduit. An exhaust gas recirculation conduit fluidly communicates with the exhaust gas conduit to divert a portion of exhaust gas to a low pressure exhaust gas recirculation branch extending between the exhaust gas recirculation conduit and an engine intake system for delivery of exhaust gas thereto. A high pressure exhaust gas recirculation branch extends between the exhaust gas recirculation conduit and the compressor intake and delivers exhaust gas to the compressor for mixing with a compressed intake charge for delivery to the intake system.

[Emotion Regulation and Emotional Vulnerability in Adolescents with Anxiety Disorders].

Zimmermann, Peter; Iwanski, Alexandra; Çelik, Fatma

2015-01-01

From an attachment perspective, insecure attachment patterns in both infancy and adolescence are risk factors for the development of anxiety disorders in adolescence. Dysfunctional emotion regulation and biased social information processing are possible mediating processes. This study examines differences in emotion regulation, emotional vulnerability, and behaviour inhibition in adolescents with clinical diagnosis of anxiety disorder and healthy controls. Adolescents with anxiety disorder reported more maladaptive emotion regulation depending on the specific emotion and a higher incidence of reporting hurt feelings in social interactions. In contrast, behaviour inhibition did not explain additional variance. The results suggest that adolescents with anxiety disorders show a bias in the interpretation of social interactions as frequently emotionally hurting, and the use of dysfunctional emotion regulation strategies that minimize the possibility for effective social emotion regulation by close others or therapists. The results are interpreted within attachment framework.

The impacts of balanced and exhaust mechanical ventilation on indoor radon

Fisk, W.J.; Mowris, R.J.

1987-02-01

Models for estimating radon entry rates, indoor radon concentrations, and ventilation rates in houses with a basement or a vented crawl-space and ventilated by natural infiltration, mechanical exhaust ventilation, or balanced mechanical ventilation are described. Simulations are performed for a range of soil and housing characteristics using hourly weather data for the heating season in Spokane, WA. For a house with a basement, we show that any ventilation technique should be acceptable when the soil permeability is less than approximately 10 -12 m 2 . However, exhaust ventilation leads to substantially higher indoor radon concentrations than infiltration or balanced ventilation with the same average air exchange rate when the soil permeability is 10 -10 m 2 or greater. For houses with a crawl-space, indoor radon concentrations are lowest with balanced ventilation, intermediate with exhaust ventilation, and highest with infiltration

Cordyceps sinensis (Berk.) Sacc. (Clavicipitaceae) is a famous medicinal fungus (mushroom) in Chinese herbal medicine. Polysaccharides from Cordyceps sinensis (CSP) have been identified as active ingredients responsible for its biological activities. Although many pharmacological actions of CSP have received a great deal of attention, research in this area continues. The current study was designed to investigate the effects of CSP on exhaustive exercise-induced oxidative stress. The mice were divided into four groups: control (C), low-dose CSP treated (LC), intermediate-dose CSP treated (IC) and high-dose CSP treated (HC). The treated groups received CSP (100, 200 and 400 mg/kg, ig), while the control group received drinking water for 28 days, followed by being forced to undergo exhaustive swimming exercise, and some biochemical parameters including superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), malondialdehyde (MDA) and 8-hydroxy-2'-deoxyguanosine (8-OHdG) were measured using detection kits according to the manufacturers' instructions. Compared with the C group, exhaustive swimming time was significantly prolonged in the LC, IC and HC groups (p activities in serum, liver and muscle were significantly higher in the IC and HC groups (p activities in serum, liver and muscle were significantly higher in the LC, IC and HC groups (p activities in serum, liver and muscle were significantly higher in the HC groups (p < 0.05); MDA and 8-OHdG levels in serum, liver and muscle were significantly lower in the LC, IC and HC groups (p < 0.05). The results obtained herein indicate that CSP could ameliorate exhaustive exercise-induced oxidative stress.

The simulation process being conducted to determine the air flow effect between the original exhaust system and modified exhaust system. The simulations are conducted to investigate the flow distribution of exhaust gases that will affect the performance of the engine. The back flow pressure in the original exhaust system is predicted toward this simulation. The design modification to the exhaust port, exhaust pipe, and exhaust muffler has been done during this simulation to reduce the back flow effect. The new designs are introduced by enlarging the diameter of the exhaust port, enlarge the diameter of the exhaust pipe and created new design for the exhaust muffler. Based on the result obtained, there the pulsating flow form at the original exhaust port that will increase the velocity and resulting the back pressure occur. The result for new design of exhaust port, the velocity is lower at the valve guide in the exhaust port. New design muffler shows that the streamline of the exhaust flow move smoothly compare to the original muffler. It is proved by using the modification exhaust system, the back pressure are reduced and the engine performance can be improve.

Domingues, António; Santos, Helder; Costa, Mário

2013-01-01

This study evaluates the vehicle exhaust WHR (waste heat recovery) potential using a RC (Rankine cycle ). To this end, both a RC thermodynamic model and a heat exchanger model have been developed. Both models use as input, experimental data obtained from a vehicle tested on a chassis dynamometer. The thermodynamic analysis was performed for water, R123 and R245fa and revealed the advantage of using water as the working fluid in applications of thermal recovery from exhaust gases of vehicles equipped with a spark-ignition engine. Moreover, the heat exchanger effectiveness for the organic working fluids R123 and R245fa is higher than that for the water and, consequently, they can also be considered appropriate for use in vehicle WHR applications through RCs when the exhaust gas temperatures are relatively low. For an ideal heat exchanger, the simulations revealed increases in the internal combustion engine thermal and vehicle mechanical efficiencies of 1.4%–3.52% and 10.16%–15.95%, respectively, while for a shell and tube heat exchanger, the simulations showed an increase of 0.85%–1.2% in the thermal efficiency and an increase of 2.64%–6.96% in the mechanical efficiency for an evaporating pressure of 2 MPa. The results confirm the advantages of using the thermal energy contained in the vehicle exhaust gases through RCs. Furthermore, the present analysis demonstrates that improved evaporator designs and appropriate expander devices allowing for higher evaporating pressures are required to obtain the maximum WHR potential from vehicle RC systems. -- Highlights: ► This study evaluates the vehicle exhaust waste heat recovery potential using Rankine cycle systems. ► A thermodynamic model and a heat exchanger model were developed. ► Experimental data obtained in a vehicle tested on a chassis dynamometer was used as models input. ► Thermodynamic analysis was performed for water, R123 and R245fa. ► Results confirm advantages of using the thermal energy

Unlike the cognitive dimensions, alterations of the affective components of empathy in schizophrenia are less well understood. This study explored cognitive and affective dimensions of empathy in the context of the subjective experience of aspects of emotion processing, including emotion regulation, emotional contagion, and interpersonal distress, in individuals with schizophrenia and healthy controls. In addition, the predictive value of these parameters on psychosocial function was investigated. Fifty-five patients with paranoid schizophrenia and 55 healthy controls were investigated using the Multifaceted Empathy Test and Interpersonal Reactivity Index, as well as the Subjective Experience of Emotions and Emotional Contagion Scales. Individuals with schizophrenia showed impairments of cognitive empathy, but maintained emotional empathy. They reported significantly more negative emotional contagion, overwhelming emotions, lack of emotions, and symbolization of emotions by imagination, but less self-control of emotional expression than healthy persons. Besides cognitive empathy, the experience of a higher extent of overwhelming emotions and of less interpersonal distress predicted psychosocial function in patients. People with schizophrenia and healthy controls showed diverging patterns of how cognitive and emotional empathy related to the subjective aspects of emotion processing. It can be assumed that variables of emotion processing are important moderators of empathic abilities in schizophrenia. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Dealing with Organizational Double Binds: Three-way Interactive Effects of Role Stressors and Coping on Worker Exhaustion.

Hornung, Severin; Lampert, Bettina; Glaser, Jürgen

2016-04-01

Based on theory regarding the dynamics of organizational double binds, hypotheses were developed about interactive effects of role conflict, role ambiguity, and coping on psychological exhaustion. Hypotheses were tested in a sample of 948 civil servants employed by a government administration in Germany. The sample included 250 (26.4%) women (M age = 43.6 year, SD = 8.3) and average organizational tenure was 17.1 year (SD = 10.0). Moderated multiple regression supported the two hypothesized three-way interactions. Under conditions of high role conflict and high role ambiguity, exhaustion was lower in workers reporting high control coping than in workers reporting low control coping. Under conditions of high role conflict and high role ambiguity, worker exhaustion was more pronounced when support coping was high than when it was low. Problem-focused control coping seems crucial to maintain mental health in dealing with contradictory and unclear work role expectations. Emotion-focused support coping appears symptomatic of prolonged involvement in psychologically dysfunctional work situations that cannot otherwise be addressed. Implications are discussed in the context of growing awareness of the contradictory demands organizations impose on employees. © The Author(s) 2016.

To examine the role that work relationships have on two long-term care outcomes: job satisfaction and turnover intention. It is easy to overlook the impact that human relations have in shaping work environments that are conducive to organizational effectiveness. Employee job satisfaction and retention are important organizational outcomes. Six hundred and seventy-five nursing and other staff from 26 long-term care facilities were surveyed about their work environments, work group relationships, observed leadership practices, organizational support, job satisfaction and turnover intention. Higher job satisfaction was associated with lower emotional exhaustion burnout, higher global empowerment, higher organizational support, higher psychological empowerment, stronger work group cohesion and higher personal accomplishment. Higher turnover intention was associated with lower job satisfaction, higher emotional exhaustion burnout, more outside job opportunities, weaker work group cohesion, lower personal accomplishment and higher depersonalization. No relationship was found between leadership practices and job satisfaction or turnover intention. Stronger work group relationships, stronger sense of personal accomplishment and lower emotional exhaustion have direct effects on increasing job satisfaction and lowering turnover intention. To retain long-term care staff, attention should be paid to fostering positive work group cohesion, supporting and acknowledging staff accomplishments and minimizing staff burnout. © 2010 The Authors.

Lane, Andrew M; Wilson, Mathew

2011-07-01

The aim of this study was to investigate relationships between trait emotional intelligence and emotional state changes over the course of an ultra-endurance foot race covering a route of approximately 175 miles (282 km) and held in set stages over six days. A repeated measures field design that sought to maintain ecological validity was used. Trait emotional intelligence was defined as a relatively stable concept that should predict adaptive emotional states experienced over the duration of the race and therefore associate with pleasant emotions during a 6-stage endurance event. Thirty-four runners completed a self-report measure of trait emotional intelligence before the event started. Participants reported emotional states before and after each of the six races. Repeated measures ANOVA results showed significant variations in emotions over time and a main effect for trait emotional intelligence. Runners high in self-report trait emotional intelligence also reported higher pleasant and lower unpleasant emotions than runners low in trait emotional intelligence. Findings lend support to the notion that trait emotional intelligence associates with adaptive psychological states, suggesting that it may be a key individual difference that explains why some athletes respond to repeated bouts of hard exercise better than others. Future research should test the effectiveness of interventions designed to enhance trait emotional intelligence and examine the attendant impact on emotional responses to intense exercise during multi-stage events.

2011-02-01

The aim of this study is to gain insight into the level of emotional intelligence of mental health nurses in the Netherlands. The focus in research on emotional intelligence to date has been on a variety of professionals. However, little is known about emotional intelligence in mental health nurses. The emotional intelligence of 98 Dutch nurses caring for psychiatric patients is reported. Data were collected with the Bar-On Emotional Quotient Inventory within a cross-sectional research design. The mean level of emotional intelligence of this sample of professionals is statistically significant higher than the emotional intelligence of the general population. Female nurses score significantly higher than men on the subscales Empathy, Social Responsibility, Interpersonal Relationship, Emotional Self-awareness, Self-Actualisation and Assertiveness. No correlations are found between years of experience and age on the one hand and emotional intelligence on the other hand. The results of this study show that nurses in psychiatric care indeed score above average in the emotional intelligence required to cope with the amount of emotional labour involved in daily mental health practice. The ascertained large range in emotional intelligence scores among the mental health nurses challenges us to investigate possible implications which higher or lower emotional intelligence levels may have on the quality of care. For instance, a possible relation between the level of emotional intelligence and the quality of the therapeutic nurse-patient relationship or the relation between the level of emotional intelligence and the manner of coping with situations characterised by a great amount of emotional labour (such as caring for patients who self-harm or are suicidal). © 2010 The Authors.

Taris, Toon W; Schreurs, Paul J G

2009-05-01

This study examined the added value of emotional job demands in explaining worker well-being, relative to the effects of task characteristics, such as quantitative job demands, job control, and coworker support. Emotional job demands were expected to account for an additional proportion of the variance in well-being. Cross-sectional data were obtained from 11,361 female Dutch home care employees. Hierarchical stepwise regression analysis demonstrated that low control, low support and high quantitative demands were generally associated with lower well-being (as measured in terms of emotional exhaustion, dedication, professional accomplishment and learning). Moreover, high emotional demands were in three out of four cases significantly associated with adverse well-being, in these cases accounting for an additional 1-6% of the variance in the outcome variables. In three out of eight cases the main effects of emotional demands on well-being were qualified by support and control, such that high control and high support either buffered the adverse effects of high emotional demands on well-being or increased the positive effects thereof. All in all, high emotional demands are as important a risk factor for worker well-being as well-established concepts like low job control and high quantitative job demands.

Full Text Available The present study investigated the role of emotional intelligence and emotional schema in marital satisfaction among women. A sample of 200 married women (100 employed and 100 household women was selected randomly and completed measures of emotional schemas, emotional intelligence, and marital satisfaction. The results of stepwise regression analysis showed that attention and clarity components of emotional intelligence are significant predictors of most marital satisfaction dimensions. Also, blame, agreement, simplistic view of emotions and higher values towards emotional schemas predicted different dimensions of marital satisfaction. Based on the findings it can be concluded that the emotional intelligence and effective emotional schema play a key role in marital satisfaction.

2017-09-01

Objectives Given the important role of the autonomic nervous system (ANS) in stress regulation, astonishingly little is known about ANS functioning in burnout, a condition arising after prolonged exposure to work-related stress. The current study sought to investigate ANS modulation, as indexed by vagally-mediated heart rate variability (HRV), in relation to burnout symptomatology to (i) distinguish associations between the three dimensions of burnout [emotional exhaustion (EE), cynicism, reduced personal accomplishment] and (ii) investigate overlap in associations with depressive symptomatology. Methods Assessments of vagally-mediated HRV (ie, root mean square of successive differences, RMSSD) were conducted in a large population-based sample from the Dresden Burnout Study [N=410, mean age 42.2, standard deviation (SD) 11.2 years; 33.4% male]. Vagally-mediated HRV was assessed for 90 seconds during an emotionally-arousing situation (venipuncture, recumbent), a 335-second recumbent recovery period, and a 335-second seated resting condition. Results Results from multiple linear regression analyses revealed that EE was negatively related to RMSSD during venipuncture (=β -0.11, P=0.03) and the seated rest (β= -0.09, P=0.04) even after accounting for established ANS modulators (eg, age, body mass index). This pattern was not observed for the other dimensions of burnout. Exploratory analyses of depressive symptomatology further revealed that RMSSD was significantly and inversely associated with burnout-related symptoms but not with the core criteria of depression (eg, depressed mood). Conclusions This study presents evidence for a link between exhaustion and reduced vagal function, both in burnout and depression, suggesting that ANS modulations may not be disorder-specific but rather a psychophysiological correlate of an underlying feature shared by both conditions.

Emotional Inertia is Associated with Lower Well-Being Controlling for Differences in Emotional Context

Peter eKoval

2016-01-01

Full Text Available Previous studies have linked higher emotional inertia (i.e., a stronger autoregressive slope of emotions with lower well-being. We aimed to replicate these findings, while extending upon previous research by addressing a number of unresolved issues and controlling for potential confounds. Specifically, we report results from two studies (Ns = 100 & 202 examining how emotional inertia, assessed in response to a standardized sequence of emotional stimuli in the lab, correlates with several measures of well-being. The current studies build on previous research by examining how inertia of both positive emotions (PE and negative emotions (NE are related to both positive (e.g., life satisfaction and negative (e.g., depressive symptoms indicators of well-being, while controlling for between-person differences in the mean level and variability of emotions. Our findings replicated previous research and further revealed that a NE inertia was more strongly associated with lower well-being than PE inertia; b emotional inertia correlated more consistently with negative indicators (e.g., depressive symptoms than positive indicators (e.g., life satisfaction of well-being; and c these relationships were independent of individual differences in mean level and variability of emotions. We conclude, in line with recent findings, that higher emotional inertia, particularly of NE, may indicate increased vulnerability to depression.

Visser, Maretha; Mabota, Princess

2015-01-01

The HIV testing, treatment and care programme of the South African public healthcare system depends on HIV counselling and testing (HCT) that is primarily delivered by lay counsellors. Lay counsellors are expected to educate clients about HIV/AIDS, advocate behaviour change, convey test results and support those infected and affected to cope with the emotional and social challenges associated with HIV/AIDS. This research focuses on the emotional wellbeing of lay HCT counsellors because this influences the quality of services they provide. A mixed methods approach was used. The emotional wellbeing, level of burnout, depression and coping style of 50 lay HCT counsellors working at the City of Tshwane clinics were assessed. Additionally, five focus group discussions were conducted. The results showed that HCT counsellors reported average emotional wellbeing, high levels of emotional exhaustion and depression. They had a sense of personal accomplishment and positive coping skills. The results revealed that they may have difficulty dealing with clients' emotional distress without adequate training and supervision. This creates a dilemma for service delivery. In the light of the important role they play in service delivery, the role of the lay HCT counsellor needs to be reconsidered. HCT should develop as a profession with specific training and supervision to develop their emotional competencies to conduct effective counselling sessions.

Waste heat recovery from the exhaust of a diesel generator using Rankine Cycle

Hossain, Shekh Nisar; Bari, Saiful

2013-01-01

Highlights: • Diesel engine exhaust contains 40% energy which can be used to produce extra power. • Extra 11% power gained with optimized heat exchangers using water as working fluid. • As a result brake specific fuel consumption improved by 12%. • Parallel arrangement of heat exchangers showed better performance than series. • Optimum working fluid pressure varies with the engine power. - Abstract: Exhaust heat from diesel engines can be an important heat source to provide additional power using a separate Rankine Cycle (RC). In this research, experiments were conducted to measure the available exhaust heat from a 40 kW diesel generator using two ‘off-the-shelf’ heat exchangers. The effectiveness of the heat exchangers using water as the working fluid was found to be 0.44 which seems to be lower than a standard one. This lower performance of the existing heat exchangers indicates the necessity of optimization of the design of the heat exchangers for this particular application. With the available experimental data, computer simulations were carried out to optimize the design of the heat exchangers. Two heat exchangers were used to generate super-heated steam to expand in the turbine using two orientations: series and parallel. The optimized heat exchangers were then used to estimate additional power considering actual turbine isentropic efficiency. The proposed heat exchanger was able to produce 11% additional power using water as the working fluid at a pressure of 15 bar at rated engine load. This additional power resulted into 12% improvement in brake-specific fuel consumption (bsfc). The effects of the working fluid pressure were also investigated to maximize the additional power production. The pressure was limited to 15 bar which was constrained by the exhaust gas temperature. However, higher pressure is possible for higher exhaust gas temperatures from higher capacity engines. This would yield more additional power with further improvements in

Full Text Available Can parents burn out? The aim of this research was to examine the construct validity of the concept of parental burnout and to provide researchers which an instrument to measure it. We conducted two successive questionnaire-based online studies, the first with a community-sample of 379 parents using principal component analyses and the second with a community- sample of 1,723 parents using both principal component analyses and confirmatory factor analyses. We investigated whether the tridimensional structure of the burnout syndrome (i.e., exhaustion, inefficacy, and depersonalization held in the parental context. We then examined the specificity of parental burnout vis-à-vis professional burnout assessed with the Maslach Burnout Inventory, parental stress assessed with the Parental Stress Questionnaire and depression assessed with the Beck Depression Inventory. The results support the validity of a tri-dimensional burnout syndrome including exhaustion, inefficacy and emotional distancing with, respectively, 53.96 and 55.76% variance explained in study 1 and study 2, and reliability ranging from 0.89 to 0.94. The final version of the Parental Burnout Inventory (PBI consists of 22 items and displays strong psychometric properties (CFI = 0.95, RMSEA = 0.06. Low to moderate correlations between parental burnout and professional burnout, parental stress and depression suggests that parental burnout is not just burnout, stress or depression. The prevalence of parental burnout confirms that some parents are so exhausted that the term “burnout” is appropriate. The proportion of burnout parents lies somewhere between 2 and 12%. The results are discussed in light of their implications at the micro-, meso- and macro-levels.

Efforts to differentiate between the developmental sequelae of childhood emotional abuse and childhood emotional neglect are critical to both research and practice efforts. As an oft-identified mechanism of the effects of child maltreatment on later adjustment, emotion dysregulation represents a key potential pathway. The present study explored a higher order factor model of specific emotion regulation skills, and the extent to which these skill sets would indicate distinct developmental pathways from unique emotional maltreatment experiences to multidomain adjustment. A sample of 500 ethnoracially diverse college students reported on their experiences. A two-factor model of emotion regulation skills based on subscales of the Difficulties in Emotion Regulation Scale was revealed. Significant indirect effects of childhood emotional abuse on psychopathology and problems in social relationships were found through response-focused difficulties in emotion regulation, whereas a significant indirect effect of childhood emotional neglect on problems in social relationships was found through antecedent-focused difficulties in emotion regulation. These results are consistent with theoretical models and empirical evidence suggesting differential effects of childhood emotional abuse and emotional neglect, and provide an important indication for developing targeted interventions focusing on specific higher order emotion dysregulation skill clusters.

Research investigating the influence of emotion regulation (ER) strategies on emotional eating and diet among Chinese adolescents is scarce. The aim of this study was to test associations between two ER strategies (suppression/cognitive reappraisal), emotional eating, and an energy-rich dietary pattern. A total of 4316 adolescents from 10 high schools were surveyed. Dietary patterns were derived using factor analysis. Bivariate correlations were analyzed to examine associations between ER strategies, emotional eating behavior and an energy-rich dietary pattern, by gender. The mediating effect of emotional eating in the relationship between ER and energy-rich food consumption by gender was estimated using structural equation modeling. A higher level of suppression, but no lack of cognitive reappraisal, was associated with emotional eating in boys and girls. A higher level of suppression and lack of cognitive reappraisal were associated with a greater intake of energy-rich foods in girls only. Emotional eating mediated the relationship between a higher level of suppression and a greater intake of energy-rich food in girls. This study revealed significant associations between two ER strategies and an energy-rich dietary pattern in girls, and provided evidence that higher levels of suppression may put girls at risk for emotional eating, potentially affecting the energy-rich dietary pattern.

Full Text Available An understanding of the development of emotional knowledge can help us determine how children perceive and interpret their surroundings and color-emotion associations are one measure of the expression of a child’s emotional interpretations. Emotional understanding and color-emotion associations were examined in a sample of UK school children, aged 7-8 years. Forty primary school children (mean age = 7.38; SD = 0.49 were administered color assessment and emotional understanding tasks, and an expressive vocabulary test. Results identified significant gender differences with girls providing more appropriate and higher quality expressions of emotional understanding than boys. Children were more able to link color to positive rather than negative emotions and significant gender differences in specific color preferences were observed. The implications of adult misinterpretations of color-emotion associations in young children are discussed.

Spontaneous Facial Mimicry Is Enhanced by the Goal of Inferring Emotional States: Evidence for Moderation of "Automatic" Mimicry by Higher Cognitive Processes.

2016-01-01

A number of studies have shown that individuals often spontaneously mimic the facial expressions of others, a tendency known as facial mimicry. This tendency has generally been considered a reflex-like "automatic" response, but several recent studies have shown that the degree of mimicry may be moderated by contextual information. However, the cognitive and motivational factors underlying the contextual moderation of facial mimicry require further empirical investigation. In this study, we present evidence that the degree to which participants spontaneously mimic a target's facial expressions depends on whether participants are motivated to infer the target's emotional state. In the first study we show that facial mimicry, assessed by facial electromyography, occurs more frequently when participants are specifically instructed to infer a target's emotional state than when given no instruction. In the second study, we replicate this effect using the Facial Action Coding System to show that participants are more likely to mimic facial expressions of emotion when they are asked to infer the target's emotional state, rather than make inferences about a physical trait unrelated to emotion. These results provide convergent evidence that the explicit goal of understanding a target's emotional state affects the degree of facial mimicry shown by the perceiver, suggesting moderation of reflex-like motor activities by higher cognitive processes.

Mixed Emotions and Coping: The Benefits of Secondary Emotions

2014-01-01

The existing empirical literature suggests that during difficult situations, the concurrent experience of positive and negative affects may be ideal for ensuring successful adaptation and well-being. However, different patterns of mixed emotions may have different adaptive consequences. The present research tested the proposition that experiencing a pattern of secondary mixed emotion (i.e., secondary emotion that embrace both positive and negative affects) more greatly promotes adaptive coping than experiencing two other patterns of mixed emotional experiences: simultaneous (i.e., two emotions of opposing affects taking place at the same time) and sequential (i.e., two emotions of opposing affects switching back and forth). Support for this hypothesis was obtained from two experiments (Studies 1 and 2) and a longitudinal survey (Study 3). The results revealed that secondary mixed emotions predominate over sequential and simultaneous mixed emotional experiences in promoting adaptive coping through fostering the motivational and informative functions of emotions; this is done by providing solution-oriented actions rather than avoidance, faster decisions regarding coping strategies (Study 1), easier access to self-knowledge, and better narrative organization (Study 2). Furthermore, individuals characterized as being prone to feeling secondary mixed emotions were more resilient to stress caused by transitions than those who were characterized as being prone to feeling opposing emotions separately (Study 3). Taken together, the preliminary results indicate that the pattern of secondary mixed emotion provides individuals with a higher capacity to handle adversity than the other two patterns of mixed emotional experience.

Cheng-xiong, Pan; Jing-zhou, Zhang; Yong, Shan

2013-01-01

The effects of exhaust temperature on infrared signature (in 3–5 μm band) for a helicopter equipped with integrative infrared suppressor were numerically investigated. The internal flow of exhaust gas and the external downwash flow, as well as the mixing between exhaust gas and downwash were simulated by CFD software to determine the temperature distributions on the helicopter skin and in the exhaust plume. Based on the skin and plume temperature distributions, a forward–backward ray-tracing method was used to calculate the infrared radiation intensity from the helicopter with a narrow-band model. The results show that for a helicopter with its integrative infrared suppressor embedded inside its rear airframe, the exhaust temperature has significant influence on the plume radiation characteristics, while the helicopter skin radiation intensity has little impact. When the exhaust temperature is raised from 900 K to 1200 K, the plume radiation intensity in 3–5 μm band is increased by about 100%, while the skin radiation intensity is increased by only about 5%. In general, the effects of exhaust temperature on helicopter infrared radiation intensity are mainly concentrated on plume, especially obvious for a lower skin emissivity case. -- Highlights: ► The effect of exhaust temperature on infrared signature for a helicopter is numerically investigated. ► The impact of exhaust temperature on helicopter skin temperature is revealed. ► The impact of exhaust temperature on plume radiation characteristics is revealed. ► The impact of exhaust temperature on helicopter skin radiation is revealed. ► The impact of exhaust temperature on helicopter's total infrared radiation intensity is revealed

2016-09-13

Based on an adjusted Job Demands-Resources (JD-R) model that considers the mediation of personal resources, this study examined the relationships between two characteristics of teachers' work environment (i.e., emotional job demands and trust in colleagues) and two indicators of teachers' well-being (i.e., teaching satisfaction and emotional exhaustion). In particular, the study focused on how emotion regulation strategies (i.e., reappraisal and suppression) mediate these relationships. Data collected from a questionnaire survey of 1115 primary school teachers in Hong Kong was analyzed to test the hypothesized relationships. The results of structural equation modeling indicated that: (1) the emotional job demands of teaching were detrimental to teacher well-being, whereas trust in colleagues was beneficial; (2) both emotion regulation strategies mediated the relationships between both emotional job demands and trust in colleagues and teacher well-being; and (3) teachers who tend to use more reappraisal may be psychologically healthier than those tend to adopt more suppression. These findings support the applicability of the JD-R model to school settings and highlight the role of teachers' emotion regulation in teachers' well-being. Implications for the improvement of school environments and teachers' well-being are identified.

Perry, Sara Jansen; Rubino, Cristina; Witt, L A

2011-04-01

In an integrated test of the job demands-resources model and trait activation theory, we predicted that the general job performance of employees who also hold supervisory roles may act as a demand to subordinates, depending on levels of subordinate conscientiousness. In a sample of 313 customer service call centre employees, we found that high-conscientiousness individuals were more likely to experience emotional exhaustion, and low-conscientiousness individuals were less likely as the general job performance of their supervisor improved. The results were curvilinear, such that high-conscientiousness individuals' exhaustion levelled off with very high supervisor performance (two standard deviations above the mean), and low-conscientiousness individuals' exhaustion levelled off as supervisor performance improved from moderate to high. These findings suggest high-conscientiousness employees may efficiently handle demands presented by a low-performing coworker who is their boss, but when performance expectations are high (i.e. high-performing boss), these achievement-oriented employees may direct their resources (i.e. energy and time) towards performance-related efforts at the expense of their well-being. Conversely, low-conscientiousness employees suffer when paired with a low-performing boss, but benefit from a supervisor who demonstrates at least moderate job performance.

Emotional exhaustion and overcommitment to work are differentially associated with hypothalamus-pituitary-adrenal (HPA) axis responses to a low-dose ACTH1-24 (Synacthen) and dexamethasone-CRH test in healthy school teachers.

Evidence for a detrimental impact of chronic work stress on health has accumulated in epidemiological research. Recent studies indicate altered hypothalamus-pituitary-adrenal (HPA) axis regulation as a possible biological pathway underlying the link between stress and disease. However, the direction of dysregulation remains unclear, with reported HPA hyper- or hyporeactivity. To disentangle potential effects on different functional levels in the HPA axis, we examined responses using two pharmacological stimulation tests in 53 healthy teachers (31 females, 22 males; mean age: 49.3 years; age range: 30-64 years): a low-dose adrenocorticotrophic hormone (ACTH(1-24), Synacthen) test was used to assess adrenal cortex sensitivity and the combined dexamethasone-corticotropin releasing hormone (DEX-CRH) test to examine pituitary and adrenal cortex reactivity. Blood and saliva samples were collected at - 1,+15,+30,+45,+60,+90,+120 min. Emotional exhaustion (EE), the core dimension of burnout, was measured with the Maslach Burnout Inventory. Overcommitment (OC) was assessed according to Siegrist's effort-reward-imbalance model. We found a significant association between EE and higher plasma cortisol profiles after Synacthen (p = 0.045). By contrast, OC was significantly associated with attenuated ACTH (p = 0.045), plasma cortisol (p = 0.005), and salivary cortisol (p = 0.023) concentrations following DEX-CRH. Results support the notion of altered HPA axis regulation in chronically work-stressed teachers, with differential patterns of hyper- and hyporeactivity depending on individual stress condition and the tested functional level of the HPA axis.

Emotional Intensity and Emotion Regulation in Response to Autobiographical Memories During Dysphoria

Retrieving personal memories may provoke different emotions and a need for emotion regulation. Emotional responses have been studied scarcely in relation to autobiographical memory retrieval. We examined the emotional response to everyday involuntary (spontaneously arising) and voluntary...... (strategically retrieved) memories, and how this response may be different during dysphoria. Participants (20 dysphoric and 23 non-depressed) completed a structured diary where the intensity of basic emotions and regulation strategies employed upon retrieval of memories were rated. Brooding, memory suppression......, and emotional suppression were higher for all individuals’ involuntary memories than voluntary memories. Negative emotions and regulation strategies were greater for dysphoric individuals for both involuntary and voluntary memories after controlling for the valence of the remembered events. The results provide...

In Taiwan, a continuous increase in the number of motorcycles has made exhaust pollution one of the major emission sources of air pollutants. The regular testing program carried out by the Republic of China Environmental Protection Agency was designed to reduce air pollutant emissions by enhancing maintenance and repair. During the execution period, abundant testing results were accumulated to discuss pollutant emissions from motorcycles. Exhaust testing data of motorcycles in Taipei City from 1996 to 2005 were chosen as the basic data to survey changes in motorcycle exhaust. Effects of motorcycle age and mileage on exhaust pollution were studied. The introduction of advanced emission standards enhances the elimination of high-emitting motorcycles. The testing data indicate that the testing rate rose from approximately 50 to 70% and the failure rate changed from approximately 15 to 10%. The operation cycles of two-stroke motorcycles make them high-emitting vehicles. Concentrations of carbon monoxide and hydrocarbons are higher in two-stroke motorcycle exhaust than that in four-stroke motorcycles. In contrast, the concentration of carbon dioxide produced from complete oxidation processes is lower in exhaust from two-stroke motorcycles. Therefore, failure rates of two-stroke motorcycles are higher than those of four-stroke motorcycles and were also observed to deactivate more easily. On the basis of analytical results of testing data, we found that failure rates show a gradually increasing trend for motorcycles older than 3 yr or used for mileages greater than 10,000 km, and failure rates are highly correlated to the age/mileage of motorcycles. We reason that the accumulation of age or mileage means accumulating usage time of engines and emission control systems. Concentrations of pollutant emissions would increase because of engine wear and emission control system deactivation. After discussing changes of failure rates and pollutant emissions, some suggestions are

Emotion-related hemisphere asymmetry: subjective emotional responses to laterally presented films.

Science.gov (United States)

Wittling, W; Roschmann, R

1993-09-01

To investigate whether the cerebral hemispheres differ in their subjective emotional responses 54 adult subjects were presented two films of different emotion-related qualities (positive and negative film) either to their left or right hemisphere. The films were exposed by means of a technique for the lateralization of visual input that allows prolonged viewing while permitting free ocular scanning. Subjective emotional responses were assessed by means of a continuous rating of emotional arousal experienced during the movie as well as by retrospective ratings of ten different emotional qualities. Presenting both films to the right hemisphere resulted in stronger subjective responses in the continuous emotion rating as well as in some retrospectively assessed ratings compared to left-hemispheric presentation. The effects were more pronounced for the negative film. Taken together, the findings suggest a higher responsiveness of the right hemisphere in subjective emotional experience.

Selective gas exhaustion method

International Nuclear Information System (INIS)

Hirano, Yoichi

1998-01-01

The present invention provides a method capable of evacuating gases at an exhaustion rate which varies depending on the kind of gases. For example, in a thermonuclear experimental device, a hydrogen gas exhaustion rate is determined to 0 and an exhaustion rate for other impure gases is made greater. Namely, a baffle plate is cooled to a temperature to a level at which the vapor pressure of gases to evacuate a baffle plate is required in a pump incorporating a baffle plate, for example, a cryopump or a sorption pump. In this case, the level of the vapor pressure required for evacuating the exhaustion gas ingredients is 1 x 10 -8 Torr or less, preferably, 1 x 10 -9 Torr. In a thermonuclear experimental device, a gas having a lower boiling point next to hydrogen is neon, but neon is scarcely present in natural world. Nitrogen has a lower boiling point next thereto, and if the temperature is lowered to such a level that the vapor pressure for evacuating gases such as nitrogen, and carbon monoxide, oxygen, fluorine, argon or methane having a boiling point at or lower than nitrogen is required. Then, evacuation rate sufficient for gases other than hydrogen gas can be obtained. (I.S.)

Emotional Inertia is Associated with Lower Well-Being when Controlling for Differences in Emotional Context.

Koval, Peter; Sütterlin, Stefan; Kuppens, Peter

2015-01-01

Previous studies have linked higher emotional inertia (i.e., a stronger autoregressive slope of emotions) with lower well-being. We aimed to replicate these findings, while extending upon previous research by addressing a number of unresolved issues and controlling for potential confounds. Specifically, we report results from two studies (Ns = 100 and 202) examining how emotional inertia, assessed in response to a standardized sequence of emotional stimuli in the lab, correlates with several measures of well-being. The current studies build on previous research by examining how inertia of both positive emotions (PE) and negative emotions (NE) relates to positive (e.g., life satisfaction) and negative (e.g., depressive symptoms) indicators of well-being, while controlling for between-person differences in the mean level and variability of emotions. Our findings replicated previous research and further revealed that (a) NE inertia was more strongly associated with lower well-being than PE inertia; (b) emotional inertia correlated more consistently with negative indicators (e.g., depressive symptoms) than positive indicators (e.g., life satisfaction) of well-being; and (c) these relationships were independent of individual differences in mean level and variability of emotions. We conclude, in line with recent findings, that higher emotional inertia, particularly of NE, may be an indicator of increased vulnerability to depression.

Empathy in clinical practice: how individual dispositions, gender, and experience moderate empathic concern, burnout, and emotional distress in physicians.

Directory of Open Access Journals (Sweden)

Ezequiel Gleichgerrcht

Full Text Available To better understand clinical empathy and what factors can undermine its experience and outcome in care-giving settings, a large-scale study was conducted with 7,584 board certified practicing physicians. Online validated instruments assessing different aspects of empathy, distress, burnout, altruistic behavior, emotional awareness, and well-being were used. Compassion satisfaction was strongly associated with empathic concern, perspective taking and altruism, while compassion fatigue (burnout and secondary traumatic stress was more closely related to personal distress and alexithymia. Gender had a highly selective effect on empathic concern, with women displaying higher values, which led to a wide array of negative and devalued feelings. Years of experience did not influence dispositional measures per se after controlling for the effect of age and gender. Participants who experienced compassion fatigue with little to no compassion satisfaction showed the highest scores on personal distress and alexithymia as well as the strongest indicators of compassion fatigue. Physicians who have difficulty regulating their negative arousal and describing and identifying emotions seem to be more prone to emotional exhaustion, detachment, and a low sense of accomplishment. On the contrary, the ability to engage in self-other awareness and regulate one's emotions and the tendency to help others, seem to contribute to the sense of compassion that comes from assisting patients in clinical practice.

In this study, burnout and its internal and external factors were investigated among substance abuse counsellors (no. = 68) who worked in Centres for Prevention and Substance Abuse Treatment (no. = 18) in Croatia. Maslach Burnout Inventory was used which measured three burnout dimensions: emotional exhaustion, depersonalization and personal accomplishment; and questionnaire of internal and external burnout factors. The higher levels of emotional exhaustion and depersonalization, and the higher level of personal accomplishment were determined. Factors such as work conditions, emotions about us and work, work organization and certain personality traits showed significant relationship with three burnout dimensions. Overall, findings implicated a certain specificity of professional burnout in substance abuse counsellors, and the need for specific design of mental health care for them.

Agricultural machinery is an important source of emission of air pollutant in rural locations. Emissions of a specific tractor engine mainly depend on engine speed. Various driving methods and use of implements with different work capacities can affect the engine load. This study deals with the effects of types of tractors and operation conditions on engine emission. In this study two types of agricultural tractors (MF285 and U650) and some tillage implements such as centrifugal type spreader, boom type sprayer and rotary tiller were employed. Some of the exhausted gases from both tractors in each condition were measured such as, hydrocarbon (HC), carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2) and nitrogen oxide (NO). Engine oil temperature was measured at every step for both types of tractors. Difference between steady-state condition and operation conditions was evaluated. The results showed all exhaust gases that measured and engine oil temperature at every operation conditions are higher than steady-state condition. A general conclusion of the work was that, using various implements and employing different types of tractors effect on engine emissions. The results of variance analysis showed all exhausted gases had a significant relationship with types of implements used at 1%. Also, all exhausted gases except CO had a significant relationship with types of tractors. A further conclusion was that NO emission increased as engine oil temperature increased. The final conclusion was about the difference between MF285 and U650; using U650 at operation conditions is better than MF285 in terms of pollution.

Full Text Available Background: Anesthesiology may be stressful and most anesthesiologists develop mechanisms for coping. However, inexperienced trainee anesthesiologists seem to be vulnerable. We studied stress perception and job burnout in trainee anesthesiologists. Methods: Responses to perceived stress scale (PSS and Maslach Burnout Inventory (MBI were evaluated in 159 trainee anesthesiologists. Results: In our results, when perceived stress was increased, emotional exhaustion and depersonalization increased but personal accomplishment decreased, as expected. Perceived stress was very high in the early years of training. There was a negative correlation between age and emotional exhaustion and depersonalization, but positive correlation with personal accomplishment. Female anesthesiologists had higher personal accomplishment, but lower depersonalization points than male anesthesiologists in our study. There was no statistical association between marital status, PSS, and MBI; ≥2 children group had a significant high personal accomplishment but low depersonalization and emotional exhaustion scores. Line regression analysis showed a statistically significant relationship between PSS and emotional exhaustion and between age and depersonalization. Conclusions: Social factors such as gender and number of children affect the work life of our trainees.

Emotional preferences and goals and emotion dysregulation in children with Asperger's syndrome and typically developing children.

López-Pérez, Belén; Ambrona, Tamara; Gummerum, Michaela

2018-02-05

Emotion goals lie at the heart of emotion regulation, as people have to first decide what emotions they want to feel before engaging in emotion regulation. Given that children with Asperger's syndrome (AS) are characterized by exhibiting difficulties in emotion regulation, studying whether they display similar or different emotion goals compared to typically developing (TD) children may provide insightful information. Thirty AS and 30 TD children (10-12 years) reported about their general (i.e., how they want to feel in general) and contextualized (i.e., how they want to feel when confronting vs. collaborating with someone) emotion goals, and about their difficulties in emotion regulation through questionnaires. Results showed that both groups did not differ in their general emotional goals and in their contextualized emotion goals for happiness for collaboration and anger for confrontation. AS children only differed from TD children in a higher preference for sadness for collaboration and happiness for confrontation. These emotion goals predicted their difficulties to engage in goal-directed behaviour. The obtained results support the need to further study emotion goals as an aspect of emotion dysregulation, namely the difficulties to engage in goal-directed behaviour when experiencing different emotions. AS and TD children did not differ in their general emotion goals. AS and TD children did not vary in their preferences for happiness for collaboration and anger for confrontation. AS children only differed in a higher preference for sadness for collaboration and happiness for confrontation. Understanding emotion goals might help practitioners to develop better interventions. © 2018 The British Psychological Society.

This article presents an analysis of the relationship between the crisis of values and in the valuation, the strategy of emotional labor, and occupational burnout in the group of lay teachers of religion. In addition, the role of emotional labor as a mediator of the relationship between the crisis of values and burnout was analyzed. Three strategies of emotional labor were considered in the study: surface acting, deep acting, and expression of naturally felt emotions. The study was conducted in a group of 169 lay teachers of religion (males - 24%, females - 76%), using the Questionnaire for Investigating Crisis in Valuation developed by Oleś, the Maslach Burnout Inventory, and the Emotional Labour Scale developed by Diefendorff, Croyle and Gosserand. The crisis of values and in the valuation is an important factor responsible for occupational burnout in the group of lay teachers of religion. Surface acting and expression of naturally felt emotions mediate the relationship between crisis in the valuation and emotional exhaustion, depersonalization and lack of personal accomplishment. Surface acting increases, while the expression of naturally felt emotions decreases occupational burnout. Deep acting is not related with occupational burnout. It is justified to seek factors favoring the expression of naturally felt emotions, and also those reducing surface acting.

Particulate matter has been associated with a number of adverse health effects. Since combustion particles from vehicle exhaust and wood smoke are common constituents of ambient air, the morphology and elemental composition of particles from these two sources were analysed and compared using single particle analysis. Ambient air particles were collected in locations dominated by vehicle exhaust or residential wood smoke. To verify the source contributions to the ambient air samples, particles were collected directly from the combustion sources. All particulate samples were analysed on carbon extraction replica by transmission electron microscopy (TEM) and X-ray microanalysis (XRMA). The particles were classified into four groups based on morphology and elemental composition. Carbon aggregates were the only particles identified to originate from combustion sources and accounted for more than 88% of the particle numbers in the ambient air samples from both sources. The carbon aggregates were therefore further analysed with respect to morphology and elemental composition on germanium extraction replica. Carbon aggregates from vehicle exhaust were characterised by higher levels of Si and Ca compared to wood smoke aggregates that contained higher levels of K. The S content in aggregates from both sources was probably caused by interaction with gases in the air. Furthermore, the diameters of primary particles from vehicle exhaust were significantly smaller (27±7 nm) than the diameters for wood smoke (38±11 nm). The observed differences in elemental profiles and primary particle diameters for vehicle exhaust and wood smoke may influence the health effects caused by these particles

This study presents fundamental research on the development of a new boiler that is expected to have a higher efficiency and lower emissions than existing boilers. The thermodynamic efficiency of exhaust gas recirculation-condensed water recirculation-waste heat recovery condensing boilers (EGR-CWR-WHR CB) was calculated using thermodynamic analysis and was compared with other boilers. The results show the possibility of obtaining a high efficiency when the temperature of the exhaust gas is controlled within 50–60 °C because water in the exhaust gas is condensed within this temperature range. In addition, the enthalpy emitted by the exhaust gas for the new boiler is smaller because the amount of condensed water is increased by the high dew-point temperature and the low exhaust gas temperature. Thus, the new boiler can obtain a higher efficiency than can older boilers. The efficiency of the EGR-CWR-WHR CB proposed in this study is 93.91%, which is 7.04% higher than that of existing CB that is currently used frequently. - Highlights: • The study presents the development of a new boiler expected to have a high efficiency. • Thermodynamic efficiency of EGR-CWR-WHR condensing boiler was calculated. • Efficiency of EGR-CWR-WHR CB is 93.91%, which is 7.04% higher than existing CB

In this study, we aimed at testing the main hypotheses of the Job Demands-Resources model (JD-R) in a sample of employees (n = 205, mainly healthcare workers) of a long-term care institution located in Northern Italy. Hierarchical linear regression analyses show that almost all job demands considered were significantly associated with higher general psycho-physical exhaustion (beta ranging from 0.14 to 0.29), whereas more unfavourable scores in all job resources were associated with lower work engagement (from -0.27 to -0.51). However, also significant cross-over associations were observed, mainly between job resources and exhaustion, with effect sizes comparable with those found for the relationships between job demands and exhaustion. Hence, our study only partially supports the JD-R model. Implications of results for work-related stress management are finally discussed.

Emotional intelligence-related differences in oscillatory responses to emotional facial expressions were investigated in 48 subjects (26 men and 22 women) in age 18-30 years. Participants were instructed to evaluate emotional expression (angry, happy and neutral) of each presented face on an analog scale ranging from -100 (very hostile) to + 100 (very friendly). High emotional intelligence (EI) participants were found to be more sensitive to the emotional content of the stimuli. It showed up both in their subjective evaluation of the stimuli and in a stronger EEG theta synchronization at an earlier (between 100 and 500 ms after face presentation) processing stage. Source localization using sLORETA showed that this effect was localized in the fusiform gyrus upon the presentation of angry faces and in the posterior cingulate gyrus upon the presentation of happy faces. At a later processing stage (500-870 ms) event-related theta synchronization in high emotional intelligence subject was higher in the left prefrontal cortex upon the presentation of happy faces, but it was lower in the anterior cingulate cortex upon presentation of angry faces. This suggests the existence of a mechanism that can be selectively increase the positive emotions and reduce negative emotions.

Burnout describes a syndrome of exhaustion resulting from insufficient coping with work-related distress. We investigated if patients that are being clinically treated for burnout show insecure and unresolved attachment representation more often compared with healthy controls. 50 out of 60 consecutive burnout patients participated in the study. Mental representation of attachment was measured by using the Adult Attachment Interview. Additionally, we administered the Self Report Questionnaire to Assess Emotional Experience and Emotion Regulation and several burnout specific questionnaires. A population sample was used as control group. Burnout patients were classified as insecurely attached significantly more often than controls. Unresolved attachment status concerning loss or trauma was found significantly more often within the burnout sample. Patients with insecure attachment representation reported a lower subjective significance of work. Patients with avoidant insecure attachment showed more depersonalisation. Patients with unresolved loss/trauma reported less social support. They showed more passive-negative emotion experience and emotion regulation characterized by externalization. The results of the study suggest that an insecure or unresolved attachment representation might constitute an intrapersonal risk factor for the development of burnout syndrome. © Georg Thieme Verlag KG Stuttgart · New York.

Exhaust gas recirculation apparatus for internal combustion engine

Energy Technology Data Exchange (ETDEWEB)

Shigemori, M; Eguchi, N

1975-01-07

An exhaust gas recirculation device to reduce nitrogen oxides emission from internal combustion engines is described. The recirculation is achieved by employing a tube connecting between the exhaust pipe and intake tube. A throttle valve is installed within the exhaust pipe between the muffler and recirculation tube, and regulated by exhaust gas temperature. Whenever the gas temperature is high, the valve closes and increases the gas flow to the intake tube. A temperature sensor is installed within the exhaust pipe and controls a solenoid or magnetic air valve linking to the throttle valve through a relay. The recirculation tube can be cooled by a fan to improve the engine power.

Exposure atmospheres for a rodent inhalation toxicology study were generated from the exhaust of a 4.3-L gasoline engine coupled to a dynamometer and operated on an adapted California Unified Driving Cycle. Exposure levels were maintained at three different dilution rates. One chamber at the lowest dilution had particles removed by filtration. Each exposure atmosphere was characterized for particle mass, particle number, particle size distribution, and detailed chemical speciation. The majority of the mass in the exposure atmospheres was gaseous carbon monoxide, nitrogen oxides, and volatile organics, with small amounts of particle-bound carbon/ions and metals. The atmospheres varied according to the cycle, with the largest spikes in volatile organic and inorganic species shown during the "cold start" portion of the cycle. Ammonia present from the exhaust and rodents interacted with the gasoline exhaust to form secondary inorganic particles, and an increase in exhaust resulted in higher proportions of secondary inorganics as a portion of the total particle mass. Particle size had a median of 10-20 nm by number and approximately 150 nm by mass. Volatile organics matched the composition of the fuel, with large proportions of aliphatic and aromatic hydrocarbons coupled to low amounts of oxygenated organics. A new measurement technique revealed organics reacting with nitrogen oxides have likely resulted in measurement bias in previous studies of combustion emissions. Identified and measured particle organic species accounted for about 10% of total organic particle mass and were mostly aliphatic acids and polycyclic aromatic hydrocarbons.

The contribution of emotional empathy to approachability judgements assigned to emotional faces is context specific

Full Text Available Previous research on approachability judgements has indicated that facial expressions modulate how these judgements are made, but the relationship between emotional empathy and context in this decision-making process has not yet been examined. This study examined the contribution of emotional empathy to approachability judgements assigned to emotional faces in different contexts. One hundred and twenty female participants completed the Questionnaire Measure of Emotional Empathy. Participants provided approachability judgements to faces displaying angry, disgusted, fearful, happy, neutral and sad expressions, in three different contexts – when evaluating whether they would approach another individual to: 1 receive help; 2 give help; or 3 when no contextual information was provided. In addition, participants were also required to provide ratings of perceived threat, emotional intensity and label facial expressions. Emotional empathy significantly predicted approachability ratings for specific emotions in each context, over and above the contribution of perceived threat and intensity, which were associated with emotional empathy. Higher emotional empathy predicted less willingness to approach people with angry and disgusted faces to receive help, and a greater willingness to approach people with happy faces to receive help. Higher emotional empathy also predicted a greater willingness to approach people with sad faces to offer help, and more willingness to approach people with happy faces when no contextual information was provided. These results highlight the important contribution of individual differences in emotional empathy in predicting how approachability judgements are assigned to facial expressions in context.

Full Text Available Based on an adjusted Job Demands-Resources (JD-R model that considers the mediation of personal resources, this study examined the relationships between two characteristics of teachers’ work environment (i.e., emotional job demands and trust in colleagues and two indicators of teachers’ well-being (i.e., teaching satisfaction and emotional exhaustion. In particular, the study focused on how emotion regulation strategies (i.e., reappraisal and suppression mediate these relationships. Data collected from a questionnaire survey of 1115 primary school teachers in Hong Kong was analyzed to test the hypothesized relationships. The results of structural equation modeling indicated that: (1 the emotional job demands of teaching were detrimental to teacher well-being, whereas trust in colleagues was beneficial; (2 both emotion regulation strategies mediated the relationships between both emotional job demands and trust in colleagues and teacher well-being; and (3 teachers who tend to use more reappraisal may be psychologically healthier than those tend to adopt more suppression. These findings support the applicability of the JD-R model to school settings and highlight the role of teachers’ emotion regulation in teachers’ well-being. Implications for the improvement of school environments and teachers’ well-being are identified.

Full Text Available The vast majority of past correctional staff burnout studies have focused on the possible antecedents of job burnout. Far fewer studies have been published on the possible outcomes of burnout among correctional staff. This study examined the effects of the emotional exhaustion dimension of burnout on life satisfaction, support for treatment, support for punishment, absenteeism, views on use of sick leave, and turnover intent among 272 staff at a state-run Midwestern maximum security prison. Ordinary least squares (OLS regression analysis of survey data indicated that emotional burnout had significant negative associations with life satisfaction and support for treatment and significant positive relationships with support for punishment, absenteeism, views on use of sick leave (i.e., a right to be used however the employee wishes, and turnover intent. The results indicate that job burnout has negative outcomes for both staff and correctional institutions.

Tritium Aspects of Fueling and Exhaust Pumping in Magnetic Fusion Energy

Energy Technology Data Exchange (ETDEWEB)

Baylor, Larry R. [ORNL; Meitner, Steven J. [ORNL

2017-04-01

Magnetically confined fusion plasmas generate energy from deuterium-tritium (DT) fusion reactions that produce energetic 3.5 MeV alpha particles and 14 MeV neutrons. Since the DT fusion reaction rate is a strong function of plasma density, an efficient fueling source is needed to maintain high plasma density in such systems. Energetic ions in fusion plasmas are able to escape the confining magnetic fields at a much higher rate than the fusion reactions occur, thus dictating the fueling rate needed. These lost ions become neutralized and need to be pumped away as exhaust gas to be reinjected into the plasma as fuel atoms.The technology to fuel and pump fusion plasmas has to be inherently compatible with the tritium fuel. An ideal holistic solution would couple the pumping and fueling such that the pump exhaust is directly fed back into pellet formation without including impurity gases. This would greatly reduce the processing needs for the exhaust. Concepts to accomplish this are discussed along with the fueling and pumping needs for a DT fusion reactor.

The present study investigated gender differences in both emotional experience and expressivity. Heart rate (HR) was recorded as an indicator of emotional experience while the participants watched 16 video clips that induced eight types of emotion (sadness, anger, horror, disgust, neutrality, amusement, surprise, and pleasure). We also asked the participants to report valence, arousal, and motivation as indicators of emotional expressivity. Overall, the results revealed gender differences in emotional experience and emotional expressivity. When watching videos that induced anger, amusement, and pleasure, men showed larger decreases in HR, whereas women reported higher levels of arousal. There was no gender difference in HR when the participants watched videos that induced horror and disgust, but women reported lower valence, higher arousal, and stronger avoidance motivation than did men. Finally, no gender difference was observed in sadness or surprise, although there was one exception—women reported higher arousal when watching videos that induced sadness. The findings suggest that, when watching videos that induce an emotional response, men often have more intense emotional experiences, whereas women have higher emotional expressivity, particularly for negative emotions. In addition, gender differences depend on the specific emotion type but not the valence. PMID:27362361

Samaritan listening volunteers provide emotional support to people in distress or suicidal. Samaritans' has high volunteer turnover, which may be due to burnout. This study evaluated the role of demographic and psychosocial factors in predicting Samaritans listening volunteers' burnout and health status. Samaritans' listening volunteers (n = 216) from seven branches across UK completed an online survey to assess their levels of burnout (emotional exhaustion, depersonalisation, personal accomplishment), subjective health status, coping, empathy and social support. Overall, listeners showed low levels of burnout and good health. Regression analysis revealed that higher emotional exhaustion was predicted by younger age and avoidant coping style; higher depersonalisation was predicted by lower empathy fantasy and higher avoidant coping style; lower personal accomplishment scores were predicted by higher empathy personal distress and worse health status was predicted by more hours per week spent on listening duties, lower social support and higher avoidant coping style. Overall, different factors influenced different facets of burnout. However, higher use of avoidant coping style consistently predicted higher burnout and worse health status, suggesting avoidant coping is an important target for intervention.

A cleaning method for automobile exhaust through contact with sintered oxide semiconductors consisting of tin, antimony, manganese, and palladium oxides is discussed. This device has a much higher efficiency and lasts longer than any similar device developed previously consisting of oxides of iron, manganese cobalt, nickel, aluminum, and other rare earth metals. This sintered oxide semiconductor device is composed of: tin oxide: 30 wt ratio, tin hydrogen oxide: 30 wt ratio, antimony oxide: 2 wt ratio, manganese chloride: 2 wt ratio, palladium chloride: 1 wt ratio, carbon powder: 4 wt ratio, and ammonium carbonate: 10 wt ratio, for example. This device converts 100 percent of carbon monoxide into carbon dioxide at 350 C. This compound provides oxygen to CO at higher temperatures and absorbs oxygen from air at normal temperatures. There is no effect on efficiency.

The aim of this study was to compare the properties of the DFL Contrast FV-58 F-speed film (DFL Co., Rio de Janerio, Brazil) with the Kodak Insight E/F speed film (Eastman Kodak, Rochester, NY) in fresh and exhausted processing solutions. The parameters studied were the speed, average gradient and latitude. Five samples of each type of film were exposed under standardized conditions over 5 weeks. The films were developed in fresh and progressively exhausted processing solutions. Characteristic curves were constructed from values of optical density and radiation dose and were used to calculate the parameters. An analysis of variance was performed separately for film type and time. DFL Contrast FV-58 film has a speed and average gradient that is significantly higher than Insight film, whereas the values of latitude are lower. Exhausted processing solutions were not significant in the parameters studied. DFL Contrast FV-58 film has stable properties when exhausted manual processing solutions are used and can be recommended for use in dental practice, contributing to dose reduction.

Despite modern day ventilation, underground miners are exposed to diesel particulate matter (DPM) composed of elemental carbon, organic carbon, sulphates, metals and ashes. Diesel exhaust contains over 40 air contaminants that have been recognized as toxic, carcinogenic or reproductive and developmental hazards. Nearly all components of diesel exhaust interact with the human body at the bloodstream or tissue level. This presentation discussed the following 4 potential levels of threat posed by the physical and chemical nature of diesel exhaust: (1) cancer of the lungs and bladder, (2) toxins that affect the nervous, endocrine, reproductive and immune system as well as the liver and kidneys, (3) fine particulate matter that can cause premature death and an increase in respiratory illness, and (4) nitrogen oxides that contribute to increased ozone and smog. Non-cancer health effects from short-term exposure include acute irritation and respiratory symptoms. This presentation also referred to cancer risk assessments of diesel exhaust by national, state, and world health organizations. Particulate exposure standards for Canada, Quebec, Ontario and the United States were listed along with the percentage of DPM samples in excess of various exposure limits in 2008 according to Canadian underground mine data. DPM concentration levels in mines are in the range that environmental agencies would consider high for general population exposure. Solutions for underground mines include pollution control at the source; use of modern engines with certification for underground mining; emissions based maintenance; exhaust treatment; use of clean or alternative fuels such as hydrogen; regular sampling and monitoring; ventilation; training and technology transfer; and regulations. tabs., figs.

Although burnout occurs in almost all occupational groups, it is mostly observed in professions requiring face-to-face relationships with people, especially among health care workers who deal constantly with problems and expectations of people. The objective of this study was to determine the burnout levels of nurses working in surgical clinics in two countries. This descriptive study was conducted between June and September 2013. The study's population consisted of 179 nurses working in the surgical clinics of Ataturk University Research Hospital and Iran Urmiyili Shahidmotahari University Hospital. A questionnaire involving descriptive characteristics of nurses and the Maslach Burnout Inventory were used to collect the data. Nurses working in Turkey had higher mean scores of "emotional exhaustion" and "depersonalization," and a higher mean composite score. Nurses working in Iran had higher mean scores of the subscale "personal accomplishment." Although there was a statistically significant difference between both countries in terms of emotional exhaustion and personal accomplishment (P  .05). Nurses working in Turkey experienced more emotional exhaustion and less personal accomplishment compared with nurses working in Iran. In line with this result, improvements in their work environment and conditions are recommended to provide organizational support by fostering job satisfaction, preventing exhaustion by arranging shifts based on workload, and offering psychological counseling services to employees.

Burnout syndrome in physical therapists – Demographic and organizational factors

Directory of Open Access Journals (Sweden)

Urszula Pustułka-Piwnik

2014-08-01

Full Text Available Background: Professional burnout results from prolonged exposure to chronic, job-related stressors. According to Christina Maslach, professional burnout is a syndrome of emotional exhaustion, depersonalization and reduced personal accomplishment. Literature includes a number of reports on burnout syndrome within health service, but hardly ever do they make any references to physiotherapists. The purpose of this study is assessment of the level of professional burnout in a group of physiotherapists and investigating relationships between the indices of burnout syndrome and selected demographic as well as organizational variables. Material and Methods: The study group consisted of 151 physiotherapists with at least 3 years of experience, employed in various health service outposts in Krakow, Poland. The Maslach Burnout Inventory (MBI was used to measure emotional exhaustion, depersonalization and personal accomplishment. A questionnaire for the description of socio-demographic and work characteristics was used as well. Results: Job burnout among the physiotherapists was manifested by an increased emotional exhaustion and decreased sense of personal achievement. Emotional exhaustion was significantly higher among physical therapists working with adults and employed in hospitals, depersonalization was higher among men, hospital workers and employees with seniority from 15 to 19 years, personal accomplishment was decreased among men and less-educated therapists. Conclusions: The study confirmed that indicators of burnout in physiotherapists are significantly associated with selected demographic and organizational variables. It is necessary to undertake a more exhaustive study of burnout in this group of employees, and implement elements of prevention. Med Pr 2014;65(4:453–462

Chen, Stephen H; Zhou, Qing; Main, Alexandra; Lee, Erica H

2015-10-01

The present study examined 2 measures of Chinese American immigrant parents' emotional expression in the family context: self-reported emotional expressivity and observed emotional expression during a parent-child interaction task. Path analyses were conducted to examine the concurrent associations between measures of emotional expression and (a) parents' American and Chinese cultural orientations in language proficiency, media use, and social affiliation domains, and (b) parents' and teachers' ratings of children's emotion-related regulation. Results suggested that cultural orientations were primarily associated with parents' self-reported expressivity (rather than observed emotional expression), such that higher American orientations were generally associated with higher expressivity. Although parents' self-reported expressivity was only related to their own reports of children's regulation, parents' observed emotional expression was related to both parents' and teachers' reports of children's regulation. These results suggest that self-reported expressivity and observed emotional expression reflect different constructs and have differential relations to parents' cultural orientations and children's regulation.

2018-01-01

Existing self-report questionnaires for the assessment of emotional eating do not differentiate between specific types of emotions and between increased or decreased food intake in response to these emotions. Therefore, we developed a new measure of emotional eating-the Salzburg Emotional Eating Scale (SEES)-for which higher scores indicate eating more than usual in response to emotions and lower scores indicate eating less than usual in response to emotions. In study 1, a pool of items describing 40 emotional states was used. Factor analysis yielded four factors, which represented both positive ( happiness subscale) and negative emotions ( sadness, anger , and anxiety subscales). Subsequently, the scale was reduced to 20 items (5 items for each subscale) and its four-factor structure was replicated in studies 2 and 3. In all three studies, internal consistencies of each subscale were α > 0.70 and mean subscale scores significantly differed from each other such that individuals reported the strongest tendency to eat more than usual when being sad and the strongest tendency to eat less than usual when being anxious (sadness > happiness > anger > anxiety). Higher scores on the happiness subscale related to lower scores on the negative emotions subscales, lower body mass index (BMI), and lower eating pathology. In contrast, higher scores on the negative emotions subscales related to lower scores on the happiness subscale, higher BMI, and higher eating pathology. The SEES represents a useful measure for the investigation of emotional eating by increasing both specificity (differentiation between specific emotional states) and breadth (differentiation between increase and decrease of food intake) in the assessment of the emotion-eating relationship.

Young neglected children may be at risk for emotion knowledge deficits. Children with histories of neglect or with no maltreatment were initially seen at age 4 and again 1 year later to assess their emotion knowledge. Higher IQ was associated with better emotion knowledge, but neglected children had consistently poorer emotion knowledge over time compared to non-neglected children after controlling for IQ. Because both neglected status and IQ may contribute to deficits in emotional knowledge, both should be assessed when evaluating these children to appropriately design and pace emotion knowledge interventions.

Energy Technology Data Exchange (ETDEWEB)

Asperger, K.; Wischnewski, W.

1981-01-01

The sulfur content of exhaust gases can be reduced by: desulphurization of fuels; modification of processes; or treatment of resultant gases. In this paper a few selected examples from the chemical industry in the German Democratic Republic are presented. Using modified processes and treating the resultant gases, the sulphuric content of exhaust gases is effectively reduced. Methods to reduce the sulfur content of exhaust gases are described in the field of production of: sulphuric acid; viscose; fertilizers; and paraffin.

Andela, Marie; Truchot, Didier

2017-08-01

The aim of the present study was to better understand the relationship between emotional dissonance and burnout by exploring the buffering effects of re-evaluation and team reflexivity. The study was conducted with a sample of 445 nurses and healthcare assistants from a general hospital. Team reflexivity was evaluated with the validation of the French version of the team reflexivity scale (Facchin, Tschan, Gurtner, Cohen, & Dupuis, 2006). Burnout was measured with the MBI General Survey (Schaufeli, Leiter, Maslach, & Jackson, 1996). Emotional dissonance and re-evaluation were measured with the scale developed by Andela, Truchot, & Borteyrou (2015). With reference to Rimé's theoretical model (2009), we suggested that both dimensions of team reflexivity (task and social reflexivity) respond to both psychological necessities induced by dissonance (cognitive clarification and socio-affective necessities). Firstly, results indicated that emotional dissonance was related to burnout. Secondly, regression analysis confirmed the buffering role of re-evaluation and social reflexivity on the emotional exhaustion of emotional dissonance. Overall, results contribute to the literature by highlighting the moderating effect of re-evaluation and team reflexivity in analysing the relationship between emotional dissonance and burnout.

Emotional intelligence in nursing is of global interest. International studies identify that emotional intelligence influences nurses' work and relationships with patients. It is associated with compassion and care. Nursing students scored higher on measures of emotional intelligence compared to students of other study programmes. The level of emotional intelligence increases with age and tends to be higher in women. This study aims to measure the differences in emotional intelligence between nursing students with previous caring experience and those without; to examine the effects of gender on emotional intelligence scores; and to test whether nursing students score higher than engineering colleagues on emotional intelligence measures. A cross-sectional descriptive study design was used. The study included 113 nursing and 104 engineering students at the beginning of their first year of study at a university in Slovenia. Emotional intelligence was measured using the Trait Emotional Intelligence Questionnaire (TEIQue) and Schutte Self Report Emotional Intelligence Test (SSEIT). Shapiro-Wilk's test of normality was used to test the sample distribution, while the differences in mean values were tested using Student t-test of independent samples. Emotional intelligence was higher in nursing students (n = 113) than engineering students (n = 104) in both measures [TEIQue t = 3.972; p emotional intelligence scores than male students on both measures, the difference was not statistically significant [TEIQue t = -0.839; p = 0.403; SSEIT t = -1.159; p = 0.249]. EI scores in nursing students with previous caring experience were not higher compared to students without such experience for any measure [TEIQue t = -1.633; p = 0.105; SSEIT t = -0.595; p = 0.553]. Emotional intelligence was higher in nursing than engineering students, and slightly higher in women than men. It was not associated with previous caring experience. Copyright

Social anxiety and emotion regulation flexibility: considering emotion intensity and type as contextual factors.

O'Toole, Mia S; Zachariae, Robert; Mennin, Douglas S

2017-11-01

Individuals with social anxiety disorder have often been considered inflexible in their emotion regulation. The aim of this study was to investigate emotion regulation flexibility in socially anxious individuals in response to two contextual factors, namely different levels of emotion intensity and emotion type. A daily diary approach was employed, investigating emotion regulation (i.e., experiential avoidance, expressive suppression and cognitive reappraisal) in college students scoring high (N = 62; HSA) and low (N = 52; LSA) on social anxiety. Results revealed that HSAs were found to use more experiential avoidance than LSAs, especially at higher levels of negative intensity. The use of this emotion regulation strategy appeared to be driven by guilt, nervousness, and sadness. There were no between-group differences concerning the other strategies in response to varying levels of emotional intensity. Together, the results provide evidence for inflexible emotion regulation in HSAs, reflected in an unwillingness to experience negative emotions.

This study examined gender differences in emotion word use during mother-child and father-child conversations. Sixty-five Spanish mothers and fathers and their 4- (M = 53.50, SD = 3.54) and 6-year-old (M = 77.07, SD = 3.94) children participated in this study. Emotion talk was examined during a play-related storytelling task and a reminiscence task (conversation about past experiences). Mothers mentioned a higher proportion of emotion words than did fathers. During the play-related storytelling task, mothers of 4-year-old daughters mentioned a higher proportion of emotion words than did mothers of 4-year-old sons, whereas fathers of 4-year-old daughters directed a higher proportion of emotion words than did fathers of 4-year-old sons during the reminiscence task. No gender differences were found with parents of 6-year-old children. During the reminiscence task daughters mentioned more emotion words with their fathers than with their mothers. Finally, mothers' use of emotion talk was related to whether children used emotion talk in both tasks. Fathers' use of emotion talk was only related to children's emotion talk during the reminiscence task. © 2014 The British Psychological Society.

Excessive empathy has been associated with compassion fatigue in health professionals and caregivers. We investigated an effect of empathy on emotion processing in 137 healthy individuals of both sexes. We tested a hypothesis that high empathy may underlie increased sensitivity to negative emotion recognition which may interact with gender. Facial emotion stimuli comprised happy, angry, fearful, and sad faces presented at different intensities (mild and prototypical) and different durations (500ms and 2000ms). The parameters of emotion processing were represented by discrimination accuracy, response bias and reaction time. We found that higher empathy was associated with better recognition of all emotions. We also demonstrated that higher empathy was associated with response bias towards sad and fearful faces. The reaction time analysis revealed that higher empathy in females was associated with faster (compared with males) recognition of mildly sad faces of brief duration. We conclude that although empathic abilities were providing for advantages in recognition of all facial emotional expressions, the bias towards emotional negativity may potentially carry a risk for empathic distress.

Monta, William J.

1992-01-01

A pitot-rake survey of the simulated exhaust of a half-span scramjet nozzle model was conducted in the Langley 20-Inch Mach 6 Tunnel to provide an additional data set for computational fluid dynamics (CFD) code comparisons. A wind-tunnel model was tested with a 26-tube pitot rake that could be manually positioned along the mid-semispan plane of the model. The model configuration had an external expansion surface of 20 degrees and an internal cowl expansion of 12 degrees; tests were also performed with a flow fence. Tests were conducted at a free-stream Reynolds number of approximately 6.5 x 10(exp 6) per foot and a model angle of attack of -0.75 degrees. The two exhaust gas mediums that were tested were air and a Freon 12-argon mixture. Each medium was tested at two jet total pressures at approximately 28 and 14 psia. This document presents the flow-field survey results in graphical as well as tabular form, and several observations concerning the results are discussed. The surveys reveal the major expected flow-field characteristics for each test configuration. For a 50-percent freon 12 and 50-percent argon mixture by volume (Fr-Ar), the exhaust jet pressures were slightly higher than those for air. The addition of a flow fence slightly raised the pitot pressure for the Fr-Ar mixture, but it produced little change for air. For the Fr-Ar exhaust, the plume was larger and the region between the shock wave and plume was smaller.

Burnout syndrome is an emerging disease among health professionals. The aim of this study is to determine the prevalence of occupational burnout among Primary Care staff, as well as to determine the differences in prevalence between family doctors, paediatricians, nurses, administrative-officers, and social-workers, and to evaluate the different related factors. A cross-sectional, descriptive study was conducted on 178 professionals from 5 different occupational groups in 54 Primary Care centres in Navarre from September to December 2010. An anonymous, self-administered questionnaire that included: the Maslach Burnout Inventory and a questionnaire on socio-demographic and work-related factors. Burnout was detected in 39.3% of staff. Those with higher levels are administrative-officers and family doctors, with an OR compared to nurses of 4.58 and 5.37, respectively in the dimension of emotional exhaustion, 4.98 and 2.87 in depersonalization, and 8.37 for administrative-officers in personal accomplishment. An association was found between burnout and the following factors: to be a male (for the dimensions of emotional exhaustion and depersonalization, 25.5 and 31.9%, respectively), to be employed in an urban area (for emotional exhaustion and depersonalization, 20 and 27.8%, respectively), use of psychiatric medication (for emotional exhaustion, 30%), size of patient-quota (for depersonalization, with an average of 1,565 patients), and welfare pressure (for emotional exhaustion and depersonalization, averages of 170.35 and 153.54 patients/week, respectively). About one-third of Primary Care professionals have a high level of burnout, which is mainly associated with the working area, the size of the quota, and professional group, with higher prevalence in administrative-officers and family doctors.

Direct care workers (e.g., certified nursing assistants [CNAs]) employed in long-term care (LTC) are particularly vulnerable to the experience of burnout, yet they have received relatively less research attention compared to Licensed Practical Nurses and Registered Nurses. Within the burnout literature, evidence suggests that the deployment of certain coping strategies influences levels of burnout. The current study examined the extent to which coping (e.g., problem-focused, emotion-focused, and dysfunctional coping) and cognitive emotion regulation strategies (e.g., positive reappraisal) predicted burnout after controlling for covariates (age, sleep duration). Fifty-six CNAs were surveyed at four skilled nursing facilities in the United States. Dysfunctional coping was significantly associated with emotional exhaustion and depersonalization. Among cognitive emotion regulation strategies, positive reappraisal was significantly associated with depersonalization. Shorter sleep duration was associated with significantly greater depersonalization. Findings suggest the need to develop interventions for CNAs aimed at reducing dysfunctional coping strategies and increasing sleep duration.

Evaluating tractor performance and exhaust gas emissions using biodiesel from cotton seed oil

Al-lwayzy, Saddam H; Yusaf, Talal; Jensen, Troy

2012-01-01

Alternative fuels for diesel engines, such as biodiesel, have attracted much attention recently due to increasing fuel prices and the imperative to reduce emissions. The exhaust gas emissions from tractors and other agricultural machinery make a significant contribution to these emissions. The use of biodiesel in internal combustion engines (ICE) has been reported to give comparable performance to conventional diesel (CD), but with generally lower emissions. There is however, contradictory evidence of NO emissions being both higher and lower from the use of biodiesel. In this work, agriculture tractor engine performance and its emission using both CD and biodiesel from cotton seed oil (CSO-B20) mixed at a 20% blend ration has been evaluated and compared. The PTO test results showed comparable exhaust emissions between CD and CSO-B20. However, the use of CSO-B20 led to reductions in the thermal efficiency and exhaust temperature and an increase in the brake specific fuel consumption (BSFC), when compared to CD.

Exhaust gas heat recovery through secondary expansion cylinder and water injection in an internal combustion engine

Directory of Open Access Journals (Sweden)

Nassiri Toosi Ali

2017-01-01

Full Text Available To enhance thermal efficiency and increase performance of an internal combustion engine, a novel concept of coupling a conventional engine with a secondary 4-stroke cylinder and direct water injection process is proposed. The burned gases after working in a traditional 4-stroke combustion cylinder are transferred to a secondary cylinder and expanded even more. After re-compression of the exhaust gases, pre-heated water is injected at top dead center. The evaporation of injected water not only recovers heat from exhaust gases, but also increases the mass of working gas inside the cylinder, therefore improves the overall thermal efficiency. A 0-D/1-D model is used to numerically simulate the idea. The simulations outputs showed that the bottoming cycle will be more efficient at higher engines speeds, specifically in a supercharged/turbocharged engine, which have higher exhaust gas pressure that can reproduce more positive work. In the modeled supercharged engine, results showed that brake thermal efficiency can be improved by about 17%, and brake power by about 17.4%.

Exhaust system of an internal combustion engine

Energy Technology Data Exchange (ETDEWEB)

1974-09-04

A catalytic converter system for internal combustion engines is described that includes a means to maintain the catalyst temperature within a predetermined range for the efficient reduction of nitrogen oxides in the exhaust gas. Upstream of the catalytic converter, the exhaust pipe is encased in a structure such that a space is provided for the flow of a coolant around the exhaust pipe in response to the sensed catalytic temperature. A coolant control valve is actuated in response to the temperature sensor.

One central issue in social cognitive neuroscience is that perceiving emotions in others relates to activating the same emotion in oneself. In this study we sought to examine how the ability to perceive own emotions assessed with the Toronto Alexithymia Scale related to both the ability to perceive emotions depicted in point-light displays and the confidence in these perceptions. Participants observed video scenes of human interactions, rated the depicted valence, and judged their confidence in this rating. Results showed that people with higher alexithymia scores were significantly less confident about their decisions, but did not differ from people with lower alexithymia scores in the valence of their ratings. Furthermore, no modulating effect of social context on the effect of higher alexithymia scores was found. It is concluded that the used stimuli are fit to investigate the kinematic aspect of emotion perception and possibly separate people with high and low alexithymia scores via confidence differences. However, a general difference in emotion perception was not detected in the present setting.

2008-01-01

To describe the prevalence of burnout syndrome according to medical specialty and to examine the impact of work psychosocial risk factors, job satisfaction and professional characteristics on burnout syndrome among specialist physicians throughout Spain. A cross-sectional survey was carried out among 1,021 Spanish physicians. The outcome variables were the 3 dimensions of burnout syndrome: emotional exhaustion, depersonalization, and personal accomplishment. The explanatory variables were work psychosocial risk factors and job satisfaction evaluated by a stress scale specifically designed for physicians. Adjusted odds ratios and their 95% confidence intervals were calculated by logistic regression. The probability of high emotional exhaustion and depersonalization were greater in physicians exposed to a high level of contact with suffering and death and to a negative impact of work on home life. The probability of high emotional exhaustion was greater among physicians with a high work overload. The risk of low personal accomplishment was higher among physicians with low professional satisfaction and those without training activities. Dissatisfaction with relationships with patients and relatives had a negative effect on the 3 dimensions of burnout. Psychosocial work environment and job satisfaction have a negative effect on burnout syndrome, especially on emotional exhaustion and depersonalization.

The role of instrumental emotion regulation in the emotions-creativity link: how worries render individuals with high neuroticism more creative.

2014-10-01

Based on the instrumental account of emotion regulation (Tamir, 2005), the current research seeks to offer a novel perspective to the emotions-creativity debate by investigating the instrumental value of trait-consistent emotions in creativity. We hypothesize that emotions such as worry (vs. happy) are trait-consistent experiences for individuals higher on trait neuroticism and experiencing these emotions can facilitate performance in a creativity task. In 3 studies, we found support for our hypothesis. First, individuals higher in neuroticism had a greater preference for recalling worrisome (vs. happy) events in anticipation of performing a creativity task (Study 1). Moreover, when induced to recall a worrisome (vs. happy) event, individuals higher in neuroticism came up with more creative design (Study 2) and more flexible uses of a brick (Study 3) when the task was a cognitively demanding one. Further, Study 3 offers preliminary support that increased intrinsic task enjoyment and motivation mediates the relationship between trait-consistent emotion regulation and creative performance. These findings offer a new perspective to the controversy concerning the emotions-creativity relationship and further demonstrate the role of instrumental emotion regulation in the domain of creative performance.

Sczomak, David P.; Narayanaswamy, Kushal; Keating, Edward J.

2018-05-01

An engine control system of a vehicle includes a fuel control module that controls fuel injection of a first cylinder of an engine based on a first target air/fuel ratio that is fuel lean relative to a stoichiometric air/fuel ratio and that controls fuel injection of a second cylinder of the engine based on a second target air/fuel ratio that is fuel rich relative to stoichiometry. The first cylinder outputs exhaust to a first three way catalyst (TWC), and the second cylinder outputs exhaust to an exhaust gas recirculation (EGR) valve. An EGR control module controls opening of the EGR valve to: (i) a second TWC that reacts with nitrogen oxides (NOx) in the exhaust and outputs ammonia to a selective catalytic reduction (SCR) catalyst; and (ii) a conduit that recirculates exhaust back to an intake system of the engine.

Two Sides of Emotion: Exploring Positivity and Negativity in Six Basic Emotions across Cultures

Full Text Available We employ a novel paradigm to test whether six basic emotions (sadness, fear, disgust, anger, surprise, and happiness; Ekman, 1992 contain both negativity and positivity, as opposed to consisting of a single continuum between negative and positive. We examined the perceived negativity and positivity of these emotions in terms of their affective and cognitive components among Korean, Chinese, Canadian, and American students. Assessing each emotion at the cognitive and affective levels cross-culturally provides a fairly comprehensive picture of the positivity and negativity of emotions. Affective components were rated as more divergent than cognitive components. Cross-culturally, Americans and Canadians gave higher valence ratings to the salient valence of each emotion, and lower ratings to the non-salient valence of an emotion, compared to Chinese and Koreans. The results suggest that emotions encompass both positivity and negativity, and there were cross-cultural differences in reported emotions. This paradigm complements existing emotion theories, building on past research and allowing for more parsimonious explanations of cross-cultural research on emotion.

Genome-wide association studies (GWAS) are a common approach for systematic discovery of single nucleotide polymorphisms (SNPs) which are associated with a given disease. Univariate analysis approaches commonly employed may miss important SNP associations that only appear through multivariate analysis in complex diseases. However, multivariate SNP analysis is currently limited by its inherent computational complexity. In this work, we present a computational framework that harnesses supercomputers. Based on our results, we estimate a three-way interaction analysis on 1.1 million SNP GWAS data requiring over 5.8 years on the full "Avoca" IBM Blue Gene/Q installation at the Victorian Life Sciences Computation Initiative. This is hundreds of times faster than estimates for other CPU based methods and four times faster than runtimes estimated for GPU methods, indicating how the improvement in the level of hardware applied to interaction analysis may alter the types of analysis that can be performed. Furthermore, the same analysis would take under 3 months on the currently largest IBM Blue Gene/Q supercomputer "Sequoia" at the Lawrence Livermore National Laboratory assuming linear scaling is maintained as our results suggest. Given that the implementation used in this study can be further optimised, this runtime means it is becoming feasible to carry out exhaustive analysis of higher order interaction studies on large modern GWAS.

Diesel Engine Exhaust: Basis for Occupational Exposure Limit Value.

Science.gov (United States)

Taxell, Piia; Santonen, Tiina

2017-08-01

Diesel engines are widely used in transport and power supply, making occupational exposure to diesel exhaust common. Both human and animal studies associate exposure to diesel exhaust with inflammatory lung effects, cardiovascular effects, and an increased risk of lung cancer. The International Agency for Research on Cancer has evaluated diesel exhaust as carcinogenic to humans. Yet national or regional limit values for controlling occupational exposure to diesel exhaust are rare. In recent decades, stricter emission regulations have led to diesel technologies evolving significantly, resulting in changes in exhaust emissions and composition. These changes are also expected to influence the health effects of diesel exhaust. This review provides an overview of the current knowledge on the health effects of diesel exhaust and the influence of new diesel technologies on the health risk. It discusses the relevant exposure indicators and perspectives for setting occupational exposure limit values for diesel exhaust, and outlines directions for future research. The review is based on a collaborative evaluation report by the Nordic Expert Group for Criteria Documentation of Health Risks from Chemicals and the Dutch Expert Committee on Occupational Safety. © The Author 2017.

2009-06-01

Alterations of the mechanical patterns during an exhaustive pedaling exercise have been previously shown. We designed the present study to test the hypothesis that these alterations in the biomechanics of pedaling, which occur during exhaustive exercise, are linked to changes in the activity patterns of lower limb muscles. Ten well-trained cyclists were tested during a limited time to exhaustion, performing 80% of maximal power tolerated. Pedal force components were measured continuously using instrumented pedals and were synchronized with surface EMG signals measured in 10 lower limb muscles. The results confirmed most of the alterations of the mechanical patterns previously described in the literature. The magnitude of the root mean squared of the EMG during the complete cycle (RMScycle) for tibialis anterior and gastrocnemius medialis decreased significantly (P < 0.05) from 85% and 75% of Tlim, respectively. A higher RMScycle was obtained for gluteus maximus (P < 0.01) and biceps femoris (P < 0.05) from 75% of Tlim. The k values that resulted from the cross-correlation technique indicated that the activities of six muscles (gastrocnemius medialis, gastrocnemius lateralis, tibialis anterior, vastus lateralis, vastus medialis, and rectus femoris) were shifted forward in the cycle at the end of the exercise. The large increases in activity for gluteus maximus and biceps femoris, which are in accordance with the increase in force production during the propulsive phase, could be considered as instinctive coordination strategies that compensate for potential fatigue and loss of force of the knee extensors (i.e., vastus lateralis and vastus medialis) by a higher moment of the hip extensors.

To determine the psycho-emotional stress we have used adaptive varint of H.Ayzenko method that include an anxiety, frustration, aggressiveness and rigidity, through questionnaires. According to a survey results of the state of psycho-emotional state low levels of stress resistance were found in students in learning activities, indicating that students are exposed to the negative impact of the environment. It should also be noted that the level of emotional condition of students depends on the personal experience of stressful situations that arise in students’ lives.

采用2×3组间设计,检测特质应对(积极与消极)与展现规则(积极、消极、无规则)对情绪劳动的影响.结果表明,积极应对引起更多深层动作;积极规则下出现较少表层扮演(与消极应对比).积极和消极规则都引起较多深层和表层动作.积极应对在积极规则下表层扮演较少(与消极规则比);消极应对在积极规则下表层扮演较多(与消极规则比).研究提示,特质情绪性可能是调节展现规则与情绪劳动关系的重要因为.%Emotional labor is likely to occur when one's feeling differed from situational demands in service working setting. Two basic emotional labor strategies (e.g., surface acting and deep acting)have been intensely investigated and demonstrated on diverse implications for personnel mental health. Deep acting would activate more cognitive and emotional energy than surface acting so as to have a contribution on better self-authentic feeling and less emotional exhausted. However, literatures demonstrate that emotional display rules have different effects on emotional labor straregies but conclusions are inconsistent. The present study aimed to explore how Trait Coping Styles which reflect the coping aspects of personality in responding to stressful situations interact wiih Emotional Display Rules from professional & organizational demands and then affect strategies of emotional labor in some degree. The study was conducted by a 2×3 design experiment. The subjects were selected by Trait Coping Styles Scale (Jiang. 1999) and grouped as Trait Positive Coping Style (n=54) and Trait Negative Coping Style (n=51). Each group was further randomly divided into 3 subgroups, namely positive display rule, negative display rule and control condition (no display rule). Emotional display rules were manipulated by instructions before an emotional work task (a public speech). The experiment arranged a memory task to elicit tense mood before the experiment to facilitate

Donohue, Meghan Rose; Goodman, Sherryl H; Tully, Erin C

Risk for internalizing problems and social skills deficits likely emerges in early childhood when emotion processing and social competencies are developing. Positively biased processing of social information is typical during early childhood and may be protective against poorer psychosocial outcomes. We tested the hypothesis that young children with relatively less positively biased attention to, interpretations of, and attributions for their mother's emotions would exhibit poorer prosocial skills and more internalizing problems. A sample of 4- to 6-year-old children ( N =82) observed their mothers express happiness, sadness and anger during a simulated emotional phone conversation. Children's attention to their mother when she expressed each emotion was rated from video. Immediately following the phone conversation, children were asked questions about the conversation to assess their interpretations of the intensity of mother's emotions and misattributions of personal responsibility for her emotions. Children's prosocial skills and internalizing problems were assessed using mother-report rating scales. Interpretations of mother's positive emotions as relatively less intense than her negative emotions, misattributions of personal responsibility for her negative emotions, and lack of misattributions of personal responsibility for her positive emotions were associated with poorer prosocial skills. Children who attended relatively less to mother's positive than her negative emotions had higher levels of internalizing problems. These findings suggest that children's attention to, interpretations of, and attributions for their mother's emotions may be important targets of early interventions for preventing prosocial skills deficits and internalizing problems.

The ability to identify the cause of another person's emotional reaction is an important component associated with improved success of social relationships and survival. Although many studies have investigated the mechanisms involved in emotion recognition, very little is currently known regarding the processes involved during emotion attribution decisions. Research on complementary "emotion understanding" mechanisms, including empathy and theory of mind, has demonstrated that emotion understanding decisions are often made through relatively emotion- or cognitive-based processing streams. The current study was designed to investigate the behavioral and brain mechanisms involved in emotion attribution decisions. We predicted that dual processes, emotional and cognitive, are engaged during emotion attribution decisions. Sixteen healthy adults completed the Interpersonal Reactivity Index to characterize individual differences in tendency to make emotion- versus cognitive-based interpersonal decisions. Participants then underwent functional MRI while making emotion attribution decisions. We found neuroimaging evidence that emotion attribution decisions engage a similar brain network as other forms of emotion understanding. Further, we found evidence in support of a dual processes model involved during emotion attribution decisions. Higher scores of personal distress were associated with quicker emotion attribution decisions and increased anterior insula activity. Conversely, higher scores in perspective taking were associated with delayed emotion attribution decisions and increased prefrontal cortex and premotor activity. These findings indicate that the making of emotion attribution decisions relies on dissociable emotional and cognitive processing streams within the brain. (c) 2015 APA, all rights reserved).

Growing interest in emotion regulation is reflected in the studies of cognitive and social development.However,the extant studies mainly highlight how different emotion regulatory strategies contribute to their related developmental construct and ignore the development of emotion regulation itself.Recent studies suggest that the change of emotional experience,emotional intelligence,and emotional regulation attitude could predict and explain the development of emotional regulation.Based on the framework of the process model proposed by Gross and Levenson,our present study explored the contribution of emotional experience,emotional intelligence, and emotional regulation attitude to emotional regulation in a developmental scope.The adaptive functions of different emotion regulatory strategies were discussed as well. We adopted the longitudinal design and examined 569 junior students（Grade 6 and Grade 8 students from Shanghai junior middle schools） in the first semester of the academic year.After ten months,we examined them again.In the second phase of the study,469 of 569 students（who became Grade 7 and Grade 9 students） participated in the test.In each phase of the study,the students completed the demographic information,Emotion Regulation Questionnaire,Daily Emotion Scale,Traits Meta-Mood Scale,and Emotional Attitude Questionnaire. There are several important results and conclusion.Compared with Phase 2,adolescents experienced more positive emotion,reported a stronger up-and-down-regulation attitude,and up-regulated their emotion habitually when encountering positive emotional episodes in Phase 1.Adolescents who reported higher changes of both positive and negative emotion experience would use more and more up-regulation during the development.Nevertheless,compared with the positive emotion experience,higher changes of down-regulation using were reported by the adolescents who experienced more negative emotion when growing up.Adolescents who reported higher

Emotional foundations of cognitive control

2015-01-01

Often seen as the paragon of higher cognition, here we suggest that cognitive control is dependent on emotion. Rather than asking whether control is influenced by emotion, we ask whether control itself can be understood as an emotional process. Reviewing converging evidence from cybernetics, animal research, cognitive neuroscience, and social and personality psychology, we suggest that cognitive control is initiated when goal conflicts evoke phasic changes to emotional primitives that both focus attention on the presence of goal conflicts and energize conflict resolution to support goal-directed behavior. Critically, we propose that emotion is not an inert byproduct of conflict but is instrumental in recruiting control. Appreciating the emotional foundations of control leads to testable predictions that can spur future research. PMID:25659515

Full Text Available In a high-voltage circuit breaker, the exhaust tube connects the arc zone with the exhaust volume. During the arc interruption process, the exhaust tube transports the hot gas from the arc interruption zone to the exhaust volume through its distributed holes. The design of a high performance exhaust tube in the circuit breaker development aims for well controlled hot gas evacuation mass flow and pressure waves. In this paper, the exhaust tube behaviour is investigated using Computational Fluid Dynamics (CFD. To verify the CFD simulation, a basic experimental study with pressure measurements at different positions of the exhaust tube is performed. Further, the design parameters influencing the exhaust tube behaviour and circuit breaker performance are investigated and discussed.

The present study investigated the relationship between posttraumatic stress disorder (PTSD) and emotional eating in a sample of medically healthy and medication-free adults. Participants with PTSD (n = 44) and control participants free of lifetime psychiatric history (n = 49) completed a measure of emotional eating. Emotional eating is the tendency to eat or overeat in response to negative emotions. PTSD participants exhibited greater emotional eating than control participants (η(2)  = .20) and emotional eating increased with higher PTSD symptom severity (R(2)  = .11). Results supported the stress-eating-obesity model whereby emotional eating is a maladaptive response to stressors. Over time, this could lead to weight gain, particularly abdominal stores, and contribute to higher risk for comorbid medical disorders. Findings suggest the importance of future longitudinal research to understand whether emotional eating contributes to the high rates of obesity, diabetes, and heart disease in PTSD.

Emotional experience during psychotherapy is considered a core mechanism of change. Yet the sheer experience itself may not necessarily be beneficial; instead, the trajectories of emotional experience need to be explored as possible predictors of treatment outcomes. This study investigated whether clients' pre-treatment levels of emotion regulation and symptoms predicted patterns of session-to-session change in emotional experience. We also explored which patterns better predict clients' improvement in emotion regulation and symptoms from pre- to post treatment. One-hundred and seven clients undergoing psychodynamic psychotherapy completed questionnaires on their symptoms and emotion regulation at pre- and post- treatment. They also reported their level of emotional experience at the end of each session. Pre-treatment symptoms and difficulties in emotion regulation predicted greater instability in emotional experience. Higher mean levels of emotional experience during treatment were associated with an improvement in emotion regulation, and greater stability during treatment was associated with improvement in emotion regulation and symptoms. These findings lend weight to the idea that experiencing emotion in the therapeutic environment has significant implications for clients' ability to manage their emotions outside the session. However, emotions experienced in an unstable manner within therapy are associated with poorer outcomes. Clinical and methodological significance of this article: Therapists can benefit from observing the patterns and not only the level of their clients' emotional experiences. The identification of clients' difficulties early in treatment may help therapists guide clients through the delicate process of carefully attending to their emotions.

Capture of Heat Energy from Diesel Engine Exhaust

Energy Technology Data Exchange (ETDEWEB)

Diesel generators produce waste heat as well as electrical power. About one-third of the fuel energy is released from the exhaust manifolds of the diesel engines and normally is not captured for useful applications. This project studied different waste heat applications that may effectively use the heat released from exhaust of Alaskan village diesel generators, selected the most desirable application, designed and fabricated a prototype for performance measurements, and evaluated the feasibility and economic impact of the selected application. Exhaust flow rate, composition, and temperature may affect the heat recovery system design and the amount of heat that is recoverable. In comparison with the other two parameters, the effect of exhaust composition may be less important due to the large air/fuel ratio for diesel engines. This project also compared heat content and qualities (i.e., temperatures) of exhaust for three types of fuel: conventional diesel, a synthetic diesel, and conventional diesel with a small amount of hydrogen. Another task of this project was the development of a computer-aided design tool for the economic analysis of selected exhaust heat recovery applications to any Alaskan village diesel generator set. The exhaust heat recovery application selected from this study was for heating. An exhaust heat recovery system was fabricated, and 350 hours of testing was conducted. Based on testing data, the exhaust heat recovery heating system showed insignificant effects on engine performance and maintenance requirements. From measurements, it was determined that the amount of heat recovered from the system was about 50% of the heat energy contained in the exhaust (heat contained in exhaust was evaluated based on environment temperature). The estimated payback time for 100% use of recovered heat would be less than 3 years at a fuel price of $3.50 per gallon, an interest rate of 10%, and an engine operation of 8 hours per day. Based on experimental data

In the present study, we investigated whether expressing emotional states using a simple line drawing to represent a robot's face can serve to elicit altruistic behavior from humans. An experimental investigation was conducted in which human participants interacted with a humanoid robot whose facial expression was shown on an LCD monitor that was mounted as its head (Study 1). Participants were asked to play the ultimatum game, which is usually used to measure human altruistic behavior. All participants were assigned to be the proposer and were instructed to decide their offer within 1 min by controlling a slider bar. The corners of the robot's mouth, as indicated by the line drawing, simply moved upward, or downward depending on the position of the slider bar. The results suggest that the change in the facial expression depicted by a simple line drawing of a face significantly affected the participant's final offer in the ultimatum game. The offers were increased by 13% when subjects were shown contingent changes of facial expression. The results were compared with an experiment in a teleoperation setting in which participants interacted with another person through a computer display showing the same line drawings used in Study 1 (Study 2). The results showed that offers were 15% higher if participants were shown a contingent facial expression change. Together, Studies 1 and 2 indicate that emotional expression in simple line drawings of a robot's face elicits the same higher offer from humans as a human telepresence does.

Removing method for radon gas exhausted from nuclear fuel material

International Nuclear Information System (INIS)

Kato, Kenji.

1993-01-01

A centrifugal separator is disposed in the midway of an exhaustion pipe of a nuclear fuel handling facility, and exhausted gases are sent into a rotational cylinder of the separator. Radon gases in the midway of exhaustion are separated from the exhaustion gases by the centrifugal force of the separator and caused to stagnate at the periphery of the circumferential wall of the rotational cylinder. At the same time, the exhaustion gases having the radon gases separated therefrom are exhausted from the periphery of a rotational shaft of the rotational cylinder. Then, the radon gases stagnated in the rotational cylinder are decayed depending on the half-decay time. With such procedures, the radon gases can be removed continuously without discharging them to the outside. Further, it is preferred that an exhaustion blower or the like for putting the inside of the nuclear fuel handing facility to a negative pressure is disposed as in a conventional case. Further, a plurality of centrifugal separators may be disposed to exhaustion pipes, to remove radon gases in the exhaust gases by a multi stage way. Radon gases can be removed in a saved space with no requirement for exchange of adsorbents or temperature control. (T.M.)

Emergency physicians are at risk of burnout, which can affect their mental health, as well as patient care. We assessed burnout level among Iranian emergency physicians and investigated demographic, work-related factors and stressors associated with higher burnout. In a cross-sectional study, we surveyed all 188 emergency medicine residents and practitioners in Iran. We measured burnout using 22-item Maslach Burnout Inventory assessing emotional exhaustion, depersonalization and personal accomplishment, also demographic factors, work related factors and sources of stress in emergency department using anonymous self-administered questionnaire. Descriptive analysis, univariate analysis to evaluate association with higher score of burnout, and multivariate logistic regression analysis to predict high burnout in 3 subscales was performed. Totally, 165 questionnaires were filled (response rate: 88%; mean age: 33.6 years, 91% male). Mean burnout scores were 22.94 for emotional exhaustion (95% CI=20.78-25.01; moderate), 9.3 for depersonalization (95% CI=8.24-10.36; moderate to high), and 31.47 for personal accomplishment (95% CI=29.87-33.07; moderate to high). Frequent reported sources of stress were shortage of equipment, problem with work physical environment, and relationship with other services. All 19 sources of stress were associated with higher score of emotional exhaustion and depersonalization; while twelve out of 19 were significantly associated with lower level of personal accomplishment. In logistic regression model, the significant predictors for high emotional exhaustion were work overload, feeling of insecurity for future career and difficulties to balance professional and private life. Burnout is high among Iranian emergency medicine practitioners and some interventions can be proposed to reduce stress.

Concerns about burnout, and its consequences, among German physicians are rising. However, data on burnout among German physicians are scarce. Also, a suspected association between burnout and German physicians' wishes to leave remains to be studied. Therefore, the extent of burnout, and the association between burnout and wishes to leave clinical practice or to go abroad for clinical work was studied in a sample of young physicians in Saxony. In a cross-sectional survey, all physicians ≤40 years and registered with the State Chamber of Physicians of Saxony, Germany (n = 5956) received a paper-pencil questionnaire inquiring about socio-demographics, job satisfaction, and wishes to leave clinical practice or to go abroad for clinical work. Response rate was 40 % (n = 2357). Burnout was measured with the German version of the Maslach Burnout Inventory - Human Services Survey (MBI) consisting of the subscales emotional exhaustion (feeling emotionally drained), depersonalization (feelings of cynicsm) and personal accomplishment (feelings of personal achievement in job). Variables associated with burnout, and the association between burnout and wishes to leave were assessed in multivariate logistic regression analyses. For emotional exhaustion participants reached a mean of 21.3 [standard deviation = 9.74], for depersonalization a mean of 9.9 [5.92], and for personal accomplishment a mean of 36.3 [6.77]. Men exhibited significantly higher depersonalization than women (11.3 [6.11] versus 9 [5.62], p satisfaction with the components "work environment" and "humaneness", were associated with a lower chance for a high degree of burnout on all subscales. Higher emotional exhaustion and lower personal accomplishment were associated with an increased chance of wishing to leave clinical practice. Higher emotional exhaustion and higher depersonalization were associated with an increased chance of wishing to go abroad for clinical work. Preventing physician

Electroencephalographic brain dynamics of memory encoding in emotionally arousing context

Directory of Open Access Journals (Sweden)

Carlos Enrique eUribe

2011-06-01

Full Text Available Emotional content/context enhances declarative memory through modulation of encoding and retrieval mechanisms. At encoding, neurophysiological data have consistently demonstrated the subsequent memory effect in theta and gamma oscillations. Yet, the existing studies were focused on the emotional content effect and let the emotional context effect unexplored. We hypothesized that theta and gamma oscillations show higher evoked/induced activity during the encoding of visual stimuli when delivered in an emotionally arousing context. Twenty-five healthy volunteers underwent evoked potentials recordings using a 21 scalp electrodes montage. They attended to an audiovisual test of emotional declarative memory being randomly assigned to either emotionally arousing or neutral context. Visual stimulus presentation was used as the time-locking event. Grand-averages of the evoked potentials and evoked spectral perturbations were calculated for each volunteer. Evoked potentials showed a higher negative deflection from 80 to 140 ms for the emotional condition. Such effect was observed over central, frontal and prefrontal locations bilaterally. Evoked theta power was higher in left parietal, central, frontal and prefrontal electrodes from -50 to 300 ms in the emotional condition. Evoked gamma power was higher in the emotional condition with a spatial distribution that overlapped at some points with the theta topography. The early theta power increase could be related to expectancy induced by auditory information processing that facilitates visual encoding in emotional contexts. Together, our results suggest that declarative memory enhancement for both emotional content and emotional context are supported by similar neural mechanisms at encoding, and offer new evidence about the brain processing of relevant environmental stimuli.

Ho, Rainbow T H; Chan, Cecilia L W; Ho, Samuel M Y

2004-11-01

Chinese persons are not known as strong in expressing emotions, especially negative ones. However, being diagnosed with cancer and going through treatment can be an emotionally traumatic experience and cancer patients are supposed to have a stronger need to express these negative feelings. The control of expression of negative emotions such as anger, anxiety and depression in Chinese female cancer survivors (n=139) was examined in the present study using the Chinese version of the Courtauld Emotional Control Scale (CECS). The reliability, internal consistency and validity of the Chinese CECS were comparable to the original English scale. Correlation analyses suggested that cancer survivors with higher emotional control tended to have higher stress, anxiety and depression levels and to adopt negative coping with cancer. Regression analysis showed that emotional control would positively predict stress level even after the effect of depressed mood was under control. Further investigations are suggested in order to elucidate the causal relationships and specific cultural factors affecting emotional control in Chinese cancer survivors and, most importantly, its effect on health outcomes.

Exhaust pressure pulsation observation from turbocharger instantaneous speed measurement

Science.gov (United States)

Macián, V.; Luján, J. M.; Bermúdez, V.; Guardiola, C.

2004-06-01

In internal combustion engines, instantaneous exhaust pressure measurements are difficult to perform in a production environment. The high temperature of the exhaust manifold and its pulsating character make its application to exhaust gas recirculation control algorithms impossible. In this paper an alternative method for estimating the exhaust pressure pulsation is presented. A numerical model is built which enables the exhaust pressure pulses to be predicted from instantaneous turbocharger speed measurements. Although the model is data based, a theoretical description of the process is also provided. This combined approach makes it possible to export the model for different engine operating points. Also, compressor contribution in the turbocharger speed pulsation is discussed extensively. The compressor contribution is initially neglected, and effects of this simplified approach are analysed.

Burnout is a highly prevalent globalized health issue that causes significant physical and psychological health problems. In Latin America research on this topic has increased in recent years, however there are no studies comparing results across countries, nor normative reference cut-offs. The present meta-analysis examines the intensity of burnout (emotional exhaustion, cynicism and personal accomplishment) in 58 adult nonclinical samples from 8 countries (Argentina, Brazil, Chile, Colombia, Ecuador, Mexico, Peru and Venezuela). We found low intensity of burnout but there are significant differences between countries in emotional exhaustion explained by occupation and language. Social and human service professionals (police officers, social workers, public administration staff) are more exhausted than health professionals (physicians, nurses) or teachers. The samples with Portuguese language score higher in emotional exhaustion than Spanish, supporting the theory of cultural relativism. Demographics (sex, age) and study variables (sample size, instrument), were not found significant to predict burnout. The effect size and confidence intervals found are proposed as a useful baseline for research and medical diagnosis of burnout in Latin American countries.

Little is known about the prognosis of patients beginning peritoneal dialysis (PD) as their last alternative. To describe the clinical-demographic profile of patients switching from hemodialysis (HD) to PD, due to exhaustion of the HD vascular access, and the occurrence of peritonitis among them. Review of the medical records of all patients in the PD program of the Hospital Roberto Santos in the city of Salvador, state of Bahia, Brazil. The study comprised 22 patients (median age, 47.9 years), 54.5% of whom were men, 84.2%, black or mulattoes, and 68.2% originated from the inner Bahia state. Peritoneal dialysis was the initial modality of renal substitutive therapy (RST) in only four of those patients. The remaining 18 patients began RST through HD, mainly on an emergency basis and by using double-lumen catheter (DLC). In a median of 7.7 months on HD, most patients (64.7%) used four or more DLCs. In only 7/18 (39%) patients, the switch from HD to PD was based on the patient';s choice; in most cases, 11/18 (61%), the reason for switching to PD was exhaustion of HD vascular access. Peritonitis was more frequent in patients switching to PD due to exhaustion of HD vascular access than in the rest of the group. Initiating RST on an emergency basis through HD and using DLC may lead to a fast exhaustion of vascular access, leaving PD as the only viable option. This inadequate mode of patient "selection" for PD is associated with a higher risk for peritonitis.
