To demonstrate the importance of including a range of working conditions in models exploring the association between health- and work-related performance. The Australian Work Outcomes Research Cost-benefit study cross-sectional screening data set was used to explore health-related absenteeism and work performance losses on a sample of approximately 78,000 working Australians, including available demographic and working condition factors. Data collected using the World Health Organization Health and Productivity Questionnaire were analyzed with negative binomial logistic regression and multinomial logistic regressions for absenteeism and work performance, respectively. Hours expected to work, annual wage, and job insecurity play a vital role in the association between health- and work-related performance for both work attendance and self-reported work performance. Australian working conditions are contributing to both absenteeism and low work performance, regardless of health status.

Cynthia J Patel

2006-10-01

Full Text Available The present study examined the relationship between family-work conflict, job performance and selected work and family characteristics in a sample of working mothers employed at a large retail organization. The hypothesis of a negative relationship between family-work conflict and job performance was rejected. Married women reported significantly higher family-work conflict than unmarried women, while women in the highest work category gained the highest job performance rating. More than half the sample indicated that paid work was more important than their housework and reported that their working had a positive impact on their families. The findings are discussed in relation to the changing work and family identities of non-career women.

To assess self-reported work ability and work performance of workers who stay at work despite chronic nonspecific musculoskeletal pain (CMP), and to explore which variables were associated with these outcomes. In a cross-sectional study we assessed work ability (Work Ability Index, single item scale 0-10) and work performance (Health and Work Performance Questionnaire, scale 0-10) among 119 workers who continued work while having CMP. Scores of work ability and work performance were categorized into excellent (10), good (9), moderate (8) and poor (0-7). Hierarchical multiple regression and logistic regression analysis was used to analyze the relation of socio-demographic, pain-related, personal- and work-related variables with work ability and work performance. Mean work ability and work performance were 7.1 and 7.7 (poor to moderate). Hierarchical multiple regression analysis revealed that higher work ability scores were associated with lower age, better general health perception, and higher pain self-efficacy beliefs (R(2) = 42 %). Higher work performance was associated with lower age, higher pain self-efficacy beliefs, lower physical work demand category and part-time work (R(2) = 37 %). Logistic regression analysis revealed that work ability ≥8 was significantly explained by age (OR = 0.90), general health perception (OR = 1.04) and pain self-efficacy (OR = 1.15). Work performance ≥8 was explained by pain self-efficacy (OR = 1.11). Many workers with CMP who stay at work report poor to moderate work ability and work performance. Our findings suggest that a subgroup of workers with CMP can stay at work with high work ability and performance, especially when they have high beliefs of pain self-efficacy. Our results further show that not the pain itself, but personal and work-related factors relate to work ability and work performance.

Chronic pain, work performance and litigation.

Blyth, Fiona M; March, Lyn M; Nicholas, Michael K; Cousins, Michael J

2003-05-01

The overall population impact of chronic pain on work performance has been underestimated as it has often been described in terms of work-related absence, excluding more subtle effects that chronic pain may have on the ability to work effectively. Additionally, most studies have focussed on occupational and/or patient cohorts and treatment seeking, rather than sampling from the general population. We undertook a population-based random digit dialling computer-assisted telephone survey with participants randomly selected within households in order to measure the impact of chronic pain on work performance. In addition, we measured the association between pain-related disability and litigation. The study took place in Northern Sydney Health Area, a geographically defined urban area of New South Wales, Australia, and included 484 adults aged 18 or over with chronic pain. The response rate was 73.4%. Working with pain was more common (on an average 83.8 days in 6 months) than lost work days due to pain (4.5 days) among chronic pain participants in full-time or part-time employment. When both lost work days and reduced-effectiveness work days were summed, an average of 16.4 lost work day equivalents occurred in a 6-month period, approximately three times the average number of lost work days. In multiple logistic regression modelling with pain-related disability as the dependent variable, past or present pain-related litigation had the strongest association (odds ratio (OR)=3.59, P=0.001). In conclusion, chronic pain had a larger impact on work performance than has previously been recognised, related to reduced performance while working with pain. A significant proportion were able to work effectively with pain, suggesting that complete relief of pain may not be an essential therapeutic target. Litigation (principally work-related) for chronic pain was strongly associated with higher levels of pain-related disability, even after taking into account other factors

Full Text Available Objectives The employment relationship is a contractual one and as such must have all the basic elements of an enforceable contract to make it legally binding. In strict contractual terms, the offer is made by the employer and formally accepted by the employee. Prior Work Once the acceptance has taken place, there is a legally binding agreement and an action will lie against the party who breaches that agreement, even though it may only just have come into existence. Results An employment contract, however, is unlike most other contracts. Although the parties will have negotiated the main terms, we shall see that a large number of terms will be implied into the agreement from all sorts of different sources and will not have been individually negotiated by the parties at all. This is what makes an employment contr act so different from other contracts. Value We think this article is an important step in the disclosure of the problem eraised by this types of labour performed in different legal labour relations.

Olsen, Espen; Bjaalid, Gunhild; Mikkelsen, Aslaug

2017-11-01

To increase understanding of workplace bullying and its relation to work climate and different outcomes among nurses. Examine a proposed bullying model including both job resource and job demands, as well as nurse outcomes reflected in job performance, job satisfaction, and work ability. Workplace bullying has been identified as some of the most damaging mechanisms in workplace settings. It is important to increase understanding of workplace bullying in relation to work climate and different outcomes among nurses. This study adopted a cross-sectional web based survey design. A sample of 2946 Registered Nurses from four public Norwegian hospitals were collected during October 2014. We analysed data using descriptive statistics, correlations, Cronbach's alpa, confirmatory factor analyses, and structural equation modelling. The majority of work climate characteristics confirmed to influence workplace bullying, and additionally had direct influence on nurse outcomes; job performance, job satisfaction, and work ability. Bullying had a mediational role between most of the work climate dimensions and nurse outcomes. This study increases our understanding of organizational antecedent of bullying among nurses. Workplace bullying among nurses functions as a mediator between the majority of work climate dimensions and outcomes related to job satisfaction and work ability. Strategies to reduce bullying should look at the study finding and specifically job resources and job demands that influence bullying and nurse outcomes. © 2017 John Wiley & Sons Ltd.

Work-family conflicts and work performance.

Science.gov (United States)

Roth, Lawrence; David, Emily M

2009-08-01

Prior research indicates that work-family conflict interferes with family far more than it interferes with work. Conservation of resources provides a possible explanation: when shifting resources from family is no longer sufficient to maintain satisfactory work performance, then workers must acquire additional resources or reduce investments in work. One source of such additional resources could be high performance peers in the work group. The performance of workers with resource-rich peers may be less adversely affected by work-family conflict. In this study, 136 employees of a wholesale distribution firm (61% women, 62% minority) working in groups of 7 to 11 in manual labor and low-level administrative jobs rated their own work-to-family conflict. Their supervisors rated workers' performance. Hierarchical regression analysis indicated that work-to-family conflict increasingly adversely affected job performance as work group performance decreased. Hence, work group performance may be an important moderator of the effects of work-family conflict.

Reciprocal Relations between Work-Related Authenticity and Intrinsic Motivation, Work Ability and Depressivity: A Two-Wave Study.

Emmerich, Astrid I; Rigotti, Thomas

2017-01-01

This study investigates the role of context-specific authenticity at work for work-related outcomes (intrinsic motivation, work ability) and depressivity. Furthermore reciprocal relations between work-related authenticity and healthy psychological functioning are investigated. Longitudinal data from 1,243 employees from 63 subsidiaries of a non-profit organization in the social sector were analyzed using multilevel structural equation modeling. Work-related authenticity at T1 predicted work ability and depressivity, but not intrinsic motivation at T2, about 6 months later. Work-related authenticity at T2 was predicted by intrinsic motivation and depressivity, but not by work ability at T1. We conclude that work-related authenticity and healthy psychological functioning are positively reinforcing each other. Thus, enabling employees to be authentic supposedly increases their well-being and is a pivotal opportunity for organizations to foster health and performance-related indicators like work ability and prevent negative health indicators like depressivity. At the same time, authenticity of employees can be fostered through workplace health promotion.

Ng, Jacky Y K; Chan, Alan H S

2018-05-14

The shortage in Hong Kong of construction workers is expected to worsen in future due to the aging population and increasing construction activity. Construction work is dangerous and to help reduce the premature loss of construction workers due to work-related disabilities, this study measured the work ability of 420 Hong Kong construction workers with a Work Ability Index (WAI) which can be used to predict present and future work performance. Given the importance of WAI, in this study the effects of individual and work-related factors on WAI were examined to develop and validate a WAI model to predict how individual and work-related factors affect work ability. The findings will be useful for formulating a pragmatic intervention program to improve the work ability of construction workers and keep them in the work force.

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.

Work-related stress adversely affects personal performance, organizational efficiency and patient care as well as costing the NHS millions of pounds each year. Reducing the effects of work-related stress is a legal duty for all employers. There are a number of resources available to help both employees and employers, such as the Health and Safety Executive stress management standards. Personal life coaching is one approach to reducing work-related stress, which is well established amongst business and management executives as well as some public sector organizations.

Linden, Michael; Baron, Stefanie; Muschalla, Beate

The International Classification of Functioning Disability and Health (ICF) differentiates between functions, activities/capacities, contextual factors and participation. Dysfunctions can result in impaired capacities, which in turn can lead to problems with participation depending on the context. Motivational and volitional deficits are intervening factors. The question is to what degree work performance (i.e. participation), motivational factors, and the inability to perform activities (i.e. dysfunctions) interact. Incapacities were measured in 213 patients (70% women) admitted to the Department of Behavioral Medicine using the Mini-ICF-Rating for Mental Disorders (Mini-ICF-APP), work performance was measured with the Endicott Work Productivity Scale (EWPS), and volitional and motivational problems in regard to work were assessed with the Arbeitsbezogenes Verhaltens- und Erlebensmuster (AVEM). Sick leave prior to admission and work-related problems were assessed in a special clinical interview. The mean global score of the Mini-ICF-APP across all patients was 0.84 +/- 0.56 (SD), corresponding to 'mild disability'. The highest disabilities in this patient population were found for 'flexibility' (item 3, 1.64 +/- 0.94); the lowest disabilities were found for 'self maintenance' (item 11, 0.19 +/- 0.44) and 'mobility' (item 12, 0.43 +/- 0.85). Partial correlations between the Mini-ICF-APP, AVEM and EWPS showed highly significant correlations between the Mini-ICF-APP and EWPS and no or weak correlations between the AVEM and the Mini-ICF-APP or EWPS. Work performance is primarily related to the inability to perform activities and incapacities, and only due to attitudes or volitional/motivational factors to a much lesser degree. Therefore, capacity and motivation can and must be separated. Copyright (c) 2010 S. Karger AG, Basel.

Working memory performance has been inconsistently reported in autism spectrum disorders (ASD). Several studies in ASD have found normal performance in digit span and poor performance in digit symbol task although these are closely related with working memory. It is assumed that poor performance in digit symbol could be explained by confirmatory behavior, which is induced due to the vague memory representation of number-symbol association. Therefore it was hypothesized that the performance of working memory task, in which vagueness did not cause confirmatory behavior, would be normal in ASD. For this purpose, the Advanced Trail Making Test (ATMT) was used. The performance of digit span, digit symbol and ATMT was compared between ASD and normal control. The digit span, digit symbol and ATMT was given to 16 ASD subjects and 28 IQ-, age- and sex-matched control subjects. The scores of these tasks were compared. A significantly lower score for ASD was found only in digit symbol compared with control subjects. There were no significant difference in digit span and working memory estimated by ATMT. Discrepancy of scores among working memory-related tasks was demonstrated in ASD. Poor digit symbol performance, normal digit span and normal working memory in ATMT implied that ASD subjects would be intact in working memory itself, and that superficial working memory dysfunction might be observed due to confirmatory behavior in digit symbol. Therefore, to evaluate working memory in ASD, tasks that could stimulate psychopathology specific to ASD should be avoided.

Human errors and work performance in a nuclear power plant control room: associations with work-related factors and behavioral coping

International Nuclear Information System (INIS)

Kecklund, Lena Jacobsson; Svenson, Ola

1997-01-01

The present study investigated the relationships between the operator's appraisal of his own work situation and the quality of his own work performance as well as self-reported errors in a nuclear power plant control room. In all, 98 control room operators from two nuclear power units filled out a questionnaire and several diaries during two operational conditions, annual outage and normal operation. As expected, the operators reported higher work demands in annual outage as compared to normal operation. In response to the increased demands, the operators reported that they used coping strategies such as increased effort, decreased aspiration level for work performance quality and increased use of delegation of tasks to others. This way of coping does not reflect less positive motivation for the work during the outage period. Instead, the operators maintain the same positive motivation for their work, and succeed in being more alert during morning and night shifts. However, the operators feel less satisfied with their work result. The operators also perceive the risk of making minor errors as increasing during outage. The decreased level of satisfaction with work result during outage is a fact despite the lowering of aspiration level for work performance quality during outage. In order to decrease relative frequencies for minor errors, special attention should be given to reduce work demands, such as time pressure and memory demands. In order to decrease misinterpretation errors special attention should be given to organizational factors such as planning and shift turnovers in addition to training. In summary, the outage period seems to be a significantly more vulnerable window in the management of a nuclear power plant than the normal power production state. Thus, an increased focus on the outage period and human factors issues, addressing the synergetic effects or work demands, organizational factors and coping resources is an important area for improvement of

The main objective of this study is to examine the relationship between indicators of non-standard work arrangements, including precarious contract, long working hours, multiple jobs, shift work, and work-related accident absence, using a representative Belgian sample and considering several socio-demographic and work characteristics. This study was based on the data of the fifth European Working Conditions Survey (EWCS). For the analysis, the sample was restricted to 3343 respondents from Belgium who were all employed workers. The associations between non-standard work arrangements and work-related accident absence were studied with multivariate logistic regression modeling techniques while adjusting for several confounders. During the last 12 months, about 11.7% of workers were absent from work because of work-related accident. A multivariate regression model showed an increased injury risk for those performing shift work (OR 1.546, 95% CI 1.074-2.224). The relationship between contract type and occupational injuries was not significant (OR 1.163, 95% CI 0.739-1.831). Furthermore, no statistically significant differences were observed for those performing long working hours (OR 1.217, 95% CI 0.638-2.321) and those performing multiple jobs (OR 1.361, 95% CI 0.827-2.240) in relation to work-related accident absence. Those who rated their health as bad, low educated workers, workers from the construction sector, and those exposed to biomechanical exposure (BM) were more frequent victims of work-related accident absence. No significant gender difference was observed. Indicators of non-standard work arrangements under this study, except shift work, were not significantly associated with work-related accident absence. To reduce the burden of occupational injuries, not only risk reduction strategies and interventions are needed but also policy efforts are to be undertaken to limit shift work. In general, preventive measures and more training on the job are needed to

In a research project about work-related issues and corporate sustainability conducted in Brazil, the goal was to better understand how work-related issues were addressed in the corporate context. Particularly, there are some specific initiatives that serve as guides to organizational decisions, which make their performance indicators for the context of corporate sustainability. 1) To explore the presence of work-related issues and their origins in corporate sustainability approach, analyzing a) corporate disclosures; b) sustainability guidelines that are identified as relevant in corporate disclosures; c) documents that are related to sustainable development and also identified as key-documents for these guidelines and initiatives. 2) To present the activity-centered ergonomics and psychodynamics of work contributions to work-related issues in a corporate sustainability approach. An exploratory study based on multiple sources of evidence that were performed from 2012 to 2013, including interviews with companies that engaged in corporate sustainability and document analysis using the content analysis approach. Work-related issues have been presented since the earliest sustainable development documents. It is feasible to construct an empirical framework for work-related issues and corporate sustainability approaches. 1) Although some authors argue that corporate sustainability has its roots based only on the environmental dimension, there is strong empirical evidence showing that social dimension aspects such as work-related issues have been present since the beginning. 2) Some indicators should be redesigned to more precisely translate the reality of some workplaces, particularly those indicators related to organizational design and mental health.

Work stressors, Chinese coping strategies, and job performance in Greater China.

The aim of this research was to jointly test effects of work stressors and coping strategies on job performance among employees in the Greater China region. A self-administered survey was conducted to collect data from three major cities in the region, namely Beijing, Hong Kong, and Taipei (N = 380). Four important work stressors were assessed: heavy workload, organizational constraints, lack of work autonomy, and interpersonal conflict. We used a four-factor model of Chinese coping strategies composed of hobbies/relaxation, active action, seeking social support, and passive adaptation. Job performance was indicated by both task performance (quantity of work, quality of work, job knowledge) and contextual performance (attendance, getting along with others). We found that: (1) work stressors were related to job performance. Specifically, workload had a positive relation with quantity of work, whereas organizational constraints had negative relations with quantity of work and attendance. In addition, interpersonal conflict had a negative relation with getting along with others. (2) Chinese positive coping strategies were positively related to job performance. Specifically, seeking social support had positive relations with quantity of work and getting along with others, whereas active action had positive relations with attendance and job knowledge. (3) Chinese passive adaptation coping behaviors were negatively related to job performance. Specifically, passive adaptation had negative relations with quantity of work, quality of work, and getting along with others. The present study thus found joint effects of work stressors and coping behaviors among Chinese employees in the Greater China region, encompassing three sub-societies of mainland China, Hong Kong, and Taiwan. Differential effects of Chinese positive and passive coping strategies were also noted. Most importantly, all these effects were demonstrated on multiple indicators of job performance, a rarely studied

Koopmans, Linda; Bernaards, Claire M; Hildebrandt, Vincent H; de Vet, Henrica C W; van der Beek, Allard J

2014-01-01

Theoretically, individual work performance (IWP) can be divided into four dimensions: task performance, contextual performance, adaptive performance, and counterproductive work behavior. However, there is no consensus on the indicators used to measure these dimensions. This study was designed to (1) identify indicators for each dimension, (2) select the most relevant indicators, and (3) determine the relative weight of each dimension in ratings of work performance. IWP indicators were identified from multiple research disciplines, via literature, existing questionnaires, and expert interviews. Subsequently, experts selected the most relevant indicators per dimension and scored the relative weight of each dimension in ratings of IWP. In total, 128 unique indicators were identified. Twenty-three of these indicators were selected by experts as most relevant for measuring IWP. Task performance determined 36% of the work performance rating, while the other three dimensions respectively determined 22%, 20% and 21% of the rating. Notable consensus was found on relevant indicators of IWP, reducing the number from 128 to 23 relevant indicators. This provides an important step towards the development of a standardized, generic and short measurement instrument for assessing IWP.

Development of visual working memory and distractor resistance in relation to academic performance.

Tsubomi, Hiroyuki; Watanabe, Katsumi

2017-02-01

Visual working memory (VWM) enables active maintenance of goal-relevant visual information in a readily accessible state. The storage capacity of VWM is severely limited, often as few as 3 simple items. Thus, it is crucial to restrict distractor information from consuming VWM capacity. The current study investigated how VWM storage and distractor resistance develop during childhood in relation to academic performance in the classroom. Elementary school children (7- to 12-year-olds) and adults (total N=140) completed a VWM task with and without visual/verbal distractors during the retention period. The results showed that VWM performance with and without distractors developed at similar rates until reaching adult levels at 10years of age. In addition, higher VWM performance without distractors was associated with higher academic scores in literacy (reading and writing), mathematics, and science for the younger children (7- to 9-year-olds), whereas these academic scores for the older children (10- to 12-year-olds) were associated with VWM performance with visual distractors. Taken together, these results suggest that VWM storage and distractor resistance develop at a similar rate, whereas their contributions to academic performance differ with age.

In this longitudinal two-wave study, bidirectional relations between work-related stress and sleep quality were examined. Moreover, it was investigated whether perseverative cognition is a potential underlying mechanism in this association, related to both work-related stress and sleep quality. A randomly selected sample of Dutch employees received an online survey in 2012 and 2013. Of all invited employees, 877 participated in both waves. Structural equation modeling was performed to analyze the data. We found evidence for reversed relations between work-related stress and sleep quality. Specifically, when controlling for perseverative cognition, work-related stress was not directly related to subsequent sleep quality, but low sleep quality was associated with an increase in work-related stress over time. Moreover, negative bidirectional associations over time were found between perseverative cognition and sleep quality, and positive bidirectional associations were found between work-related stress and perseverative cognition. Lastly, a mediation analysis showed that perseverative cognition fully mediated the relationship between work-related stress and sleep quality. The study findings suggest that perseverative cognition could be an important underlying mechanism in the association between work-related stress and sleep quality. The bidirectionality of the studied relationships could be an indication of a vicious cycle, in which work-related stress, perseverative cognition, and sleep quality mutually influence each other over time.

The aim of this study was to examine which individual and work-related characteristics predict work outcomes related to sustainable employment among male shift and day workers. Between 1 September 2005 and 31 December 2009, data on individual and work-related characteristics of N=5640 employees of Tata Steel in the Netherlands were retrieved from the Occupational Health Service and company registers. Work outcomes related to sustainable employment were (i) temporarily being placed in less strenuous work, (ii) sickness absence ≥6 weeks, and (iii) leaving the organization. Cox proportional hazard analyses were performed for all outcome measures. Similar predictors were found for shift and day workers although some differences were observed. For shift workers, high blood pressure and cardiovascular disease were important predictors for sickness absence. For day workers, insomnia was an important predictor of sickness absence ≥6 weeks. Similar predictors in magnitude and direction were found for work outcomes related to sustainable employment among shift and day workers. Interventions aimed at enhancing sustainable employability should focus on individual and work-related characteristics.

Lindström, Björn R; Bohlin, Gunilla

2011-11-01

The effect of emotional stimulus content on working memory performance has been investigated with conflicting results, as both emotion-dependent facilitation and impairments are reported in the literature. To clarify this issue, 52 adult participants performed a modified visual 2-back task with highly arousing positive stimuli (sexual scenes), highly arousing negative stimuli (violent death) and low-arousal neutral stimuli. Emotional stimulus processing was found to facilitate task performance relative to that of neutral stimuli, both in regards to response accuracy and reaction times. No emotion-dependent differences in false-alarm rates were found. These results indicate that emotional information can have a facilitating effect on working memory maintenance and processing of information.

Work domain constraints for modelling surgical performance.

Morineau, Thierry; Riffaud, Laurent; Morandi, Xavier; Villain, Jonathan; Jannin, Pierre

2015-10-01

Three main approaches can be identified for modelling surgical performance: a competency-based approach, a task-based approach, both largely explored in the literature, and a less known work domain-based approach. The work domain-based approach first describes the work domain properties that constrain the agent's actions and shape the performance. This paper presents a work domain-based approach for modelling performance during cervical spine surgery, based on the idea that anatomical structures delineate the surgical performance. This model was evaluated through an analysis of junior and senior surgeons' actions. Twenty-four cervical spine surgeries performed by two junior and two senior surgeons were recorded in real time by an expert surgeon. According to a work domain-based model describing an optimal progression through anatomical structures, the degree of adjustment of each surgical procedure to a statistical polynomial function was assessed. Each surgical procedure showed a significant suitability with the model and regression coefficient values around 0.9. However, the surgeries performed by senior surgeons fitted this model significantly better than those performed by junior surgeons. Analysis of the relative frequencies of actions on anatomical structures showed that some specific anatomical structures discriminate senior from junior performances. The work domain-based modelling approach can provide an overall statistical indicator of surgical performance, but in particular, it can highlight specific points of interest among anatomical structures that the surgeons dwelled on according to their level of expertise.

We examined energy management during work, recovery experiences after work and their connections to health, work engagement, and job performance. An online survey was completed by 1208 Finnish employees. Energy management was assessed through 13 strategies and recovery experiences through four experiences. As outcomes of recovery, we examined self-reported health, work engagement, and job performance. On average, employees applied three energy management strategies. The most beneficial strategies were work-related: shifting focus, goal setting, and helping coworkers. Both energy management and recovery experiences contributed to the outcomes. Employees benefit in terms of energy from shifting their focus to positive aspects of their jobs and demonstrating proactive social behavior at work. Recovery processes during and after work are closely connected to each other, to well-being and performance at work.

[Work related stress: from knowledge to practice].

Science.gov (United States)

Costa, G

2009-01-01

Work-related stress is a well documented condition, resulting from a distorted interaction between working conditions and individual coping resources, that may have a negative impact on workers' health and well-being, as well as nd on performance efficiency and productivity: hence high costs for workers companies and society. It is a complex multifaceted and multidimensional phenomenon, whose assessment needs a multidisciplinary approach (work management, psychology, physiology, ergonomics, sociology, medicine). That is why risk assessment and management require a careful analysis of work organization (i.e. working time, work load, autonomy, environment, human relations) and individual aspects (i.e. demography, personality, attitudes, motivation, coping strategies). The consequent actions, targeted to the individuals, groups and organizations, should be aimed at preventing or reducing work-related stress, on the one hand, and supporting and protecting the worker, on the other, considering cost/effectiveness and risk/benefit ratios. This can be achieveds to be done with the participation and close collaboration of all the social actors involved (employers, employees, technicians, work organization and occupational health experts), according to the European Framework Agreement on Work-related Stress, signed on October 2004 and included into the Italian Law Decree 81/2008.

This study aimed to compare relationships of leisure-time, household, and work-related physical activity (PA) with physical performance by age and gender in older Japanese adults. This cross-sectional study included 525 community-dwelling older adults (73.3 ± 5.2 years) recruited in 2009-2011 in Kasama City, rural Japan. We used the Physical Activity Scale for the Elderly to assess PA variables. Physical performance was evaluated by 11 performance tests: grip strength, single-leg balance, functional reach, sit-and-reach, standing time from long sitting position, sit-to-stand, timed up and go, habitual walk, hand working, and simple and choice reaction times. After adjusting for potential confounders, leisure-time PA in young-old (≤ 74 years) men correlated significantly with eight performance tests (absolute value of Spearman's partial rank correlation coefficient: r = 0.18-0.39), whereas in old-old (≥ 75 years) men it correlated with three performance tests (r = 0.20-0.23). Although leisure-time PA correlated with six performance tests (r = 0.19-0.22) in young-old women, there were no significant correlations between leisure-time PA and performance tests in old-old women. Household PA of young-old men (r = 0.20-0.23) and old-old women (r = 0.26-0.34) correlated with four performance tests. In old-old men and young-old women, no significant correlation was found between household PA and performance tests. Work-related PA did not relate significantly to any performance tests in any groups. This study showed that leisure-time PA is related to physical performance, especially in young-old men and women, and household PA is especially related in young-old men and old-old women. Our findings suggest that supporting strategies for maintaining physical functions would differ by gender and age. © 2013 Japan Geriatrics Society.

Positive effect of social work-related values on work outcomes: the moderating role of age and work situation.

Yeung, Dannii Y; Fung, Helene H; Chan, Darius K-S

2015-03-01

This study investigated the effect of social work-related values on job performance through job satisfaction and tested whether age and work situation would moderate such associations. This study consists of two parts: Part 1 is a cross-sectional survey among 299 Chinese clerical employees aged 19-60 years and Part 2 is a 14-day experience sampling study in a subsample of Part 1 (N = 67). Part 1 revealed that age moderated the effect of social work-related values on job performance through job satisfaction, with a stronger positive effect in older workers than in younger workers. Part 2 demonstrated that the moderating effect of age shown in Part 1 also varied across work situations. In particular, holding momentary social work-related values was beneficial to the task performance of older workers, and the effect was significantly stronger when they were in social situations than in nonsocial situations, whereas the effect remained weak among younger workers regardless of work context. Moreover, the moderating effect of age could be accounted for by future time perspective. This study supports socioemotional selectivity theory that goal orientation shifts toward the emphasis of interpersonal closeness when one perceives future time as increasingly limited. © The Author 2013.

The aim of this study was to examine the longitudinal effect of implementing bike desks in an office setting on physical health, cognition, and work parameters. Physical health, cognitive function, work engagement, and work performance measured before (T0) and after (T2) the intervention period were compared between office workers who used the bike desk (IG, n = 22) and those who did not (CG, n = 16). The IG cycled approximately 98 minutes/week. The IG showed a significantly lower fat percentage and a trend toward a higher work engagement at T2 relative to T0, while this was not different for the CG. No effects on other parameters of health, cognition, or work performance were found. Providing bike desks in the office positively influences employees' fat percentage and could positively influence work engagement without compromising work performance.

ADOLESCENT WORK INTENSITY, SCHOOL PERFORMANCE, AND ACADEMIC ENGAGEMENT.

Teenagers working over 20 hours per week perform worse in school than youth who work less. There are two competing explanations for this association: (1) that paid work takes time and effort away from activities that promote achievement, such as completing homework, preparing for examinations, getting help from parents and teachers, and participating in extracurricular activities; and (2) that the relationship between paid work and school performance is spurious, reflecting preexisting differences between students in academic ability, motivation, and school commitment. Using longitudinal data from the ongoing national Monitoring the Future project, this research examines the impact of teenage employment on school performance and academic engagement during the 8th, 10th, and 12th grades. We address issues of spuriousness by using a two-level hierarchical model to estimate the relationships of within-individual changes in paid work to changes in school performance and other school-related measures. Unlike prior research, we also compare youth school performance and academic orientation when they are actually working in high-intensity jobs to when they are jobless and wish to work intensively. Results indicate that the mere wish for intensive work corresponds with academic difficulties in a manner similar to actual intensive work.

2018-06-01

Prolonged sitting is a risk factor for several diseases and the prevalence of worksite-based interventions such as sit-to-stand workstations is increasing. Although their impact on sedentary behaviour has been regularly investigated, the effect of working in alternating body postures on cognitive performance is unclear. To address this uncertainty, 45 students participated in a two-arm, randomised controlled cross-over trial under laboratory conditions. Subjects executed validated cognitive tests (working speed, reaction time, concentration performance) either in sitting or alternating working postures on two separate days (ClinicalTrials.gov Identifier: NCT02863731). MANOVA results showed no significant difference in cognitive performance between trials executed in alternating, standing or sitting postures. Perceived workload did not differ between sitting and alternating days. Repeated measures ANOVA revealed significant learning effects regarding concentration performance and working speed for both days. These results suggest that working posture did not affect cognitive performance in the short term. Practitioner Summary: Prior reports indicated health-related benefits based on alternated (sit/stand) body postures. Nevertheless, their effect on cognitive performance is unknown. This randomised controlled trial showed that working in alternating body postures did not influence reaction time, concentration performance, working speed or workload perception in the short term.

To assess the work impact of symptomatic uterine fibroids (UFs). A cohort study compared 58 employed women with symptomatic UFs to 56 healthy controls. Data sources included a self-administered mail questionnaire and medical charts. At-work performance limitations and productivity loss were measured with the Work Limitations Questionnaire. Univariate and multivariate case-control group differences were tested. Based on adjusted mean scores, the UF group had significantly more at-work limitations and productivity loss than controls, while absence rates were similar. The UF group's performance was impaired 18% of the time on average versus 8% for controls (P-values, 0.005-0.040). At-work limitations were explained by depression symptoms, Non-White race/ethnicity, and poorer health-related quality of life. Fibroids and related symptoms impose a burden on the working lives' of women, their employers, and the economy.

Science laboratory behavior strategies of students relative to performance in and attitude to laboratory work

Science.gov (United States)

Okebukola, Peter Akinsola

The relationship between science laboratory behavior strategies of students and performance in and attitude to laboratory work was investigated in an observational study of 160 laboratory sessions involving 600 class five (eleventh grade) biology students. Zero-order correlations between the behavior strategies and outcome measures reveal a set of low to strong relationships. Transmitting information, listening and nonlesson related behaviors exhibited low correlations with practical skills and the attitude measure. The correlations between manipulating apparatus and observation with practical skills measures were found to be strong. Multiple correlation analysis revealed that the behaviors of students in the laboratories observed accounted for a large percentage of the variance in the scores on manipulative skills and a low percentage on interpretation of data, responsibility, initiative, and work habits. One significant canonical correlation emerged. The loadings on this canonical variate indicate that the practical skills measures, i.e., planning and design, manipulative skills and conduct of experiments, observation and recording of data, and attitude to laboratory work made primary contributions to the canonical relationship. Suggestions as to how students can be encouraged to go beyond cookbook-like laboratories and develop a more favorable attitude to laboratory work are made.

Working memory is a complex psychological construct referring to the temporary storage and active processing of information. We used functional connectivity brain network metrics quantifying local and global efficiency of information transfer for predicting individual variability in working memory performance on an n-back task in both young (n = 14) and older (n = 15) adults. Individual differences in both local and global efficiency during the working memory task were significant predictors of working memory performance in addition to age (and an interaction between age and global efficiency). Decreases in local efficiency during the working memory task were associated with better working memory performance in both age cohorts. In contrast, increases in global efficiency were associated with much better working performance for young participants; however, increases in global efficiency were associated with a slight decrease in working memory performance for older participants. Individual differences in local and global efficiency during resting-state sessions were not significant predictors of working memory performance. Significant group whole-brain functional network decreases in local efficiency also were observed during the working memory task compared to rest, whereas no significant differences were observed in network global efficiency. These results are discussed in relation to recently developed models of age-related differences in working memory.

A number of factors influence an individual's decision to take sickness absence or to remain at work while ill. The relationship between health, work characteristics, individual perceptions of work and sickness absence and performance is complex and further clarification of the interactions between these factors is necessary. To assess the relative impact of health, work characteristics and perceptions of work on absence and performance. Cross-sectional survey of two public sector organizations (n = 505). Data were analysed using multivariate linear regression to assess the individual and combined influence of each class of independent variables on the following: days sickness absence, spells of sickness absence, VAS performance and presenteeism. Characteristics of work were weakly associated with days absence and performance. Perceptions of work were more strongly associated with performance than absence. Measures of mental health, rather than physical health, had the greatest influence on ability to work. Poor health had a greater impact on work performance than work absence. When considered together, health variables accounted for the largest proportion of explained variance in both absence and performance when compared with characteristics of work and work perceptions. Using absence as a marker of health-associated compromise at work may lead to an underestimation of the impact of health on work. This study demonstrates the need to manage the impact of health problems on the workforce not only from a bio-medical perspective but also in terms of the psychological pressures and the social context in which employees work.

Emotions experienced in association with agricultural work performed in childhood--in opinions of adults.

Performance of work is related with experiencing various emotions, from positive - indicating full satisfaction with work, to negative - describing failures, and even harm caused by work. Such emotions are also experienced by children engaged in work on family farms. The objective of the study is the determination of emotions experienced in association with performing agricultural work in childhood, and indication of the factors conditioning the occurrence of positive and negative emotions. The study was conducted by the method of a diagnostic survey using a questionnaire technique, and covered a group of 482 adults from agricultural families. In childhood, positive emotions related with the performance of work are more often experienced than negative emotions. The occurrence of positive emotions is positively related with willingness to perform work activities, working time, respondent's age, age at which a child started to perform work, and age at which a child discontinued helping on a farm. The occurrence of negative emotions is positively related with unwillingness to perform work, performing work activities beyond the physical capabilities of a child, neglecting school duties, missing classes at school due to work, and with working time. With work performed in childhood are associated positive and negative emotions experienced in childhood and adulthood. The performance of work in childhood shapes emotions experienced by an adult which may affect his/her quality of life and functioning in adulthood.

In the past two decades, special attention was paid to mental health issues. The available literature suggests, for example, the relationship between the workload and mental discomfort and the occurrence of myocardial infarction. This article focuses mainly on the issue of work-related stress and its impact on mental health. In this context, it must be acknowledged that possible psychological problems due to work are not only employees problem. These difficulties can significantly affect performance - and thus they should be the concern of the employer, but also of customers, clients and patients who come into contact with the worker who might develop some mental problems, due to the nature of his work and working conditions. This article provides an overview of the various factors affecting the mental health of employees. These are, for example, work demands, working hours and workplace relations. In conclusion, it brings results of Czech study examining job stress among working population.

Work-related stress is an increasing problem in Europe. Earlier studies have stated that knowledge-work comprises working conditions which reflect a good psychosocial environment. Recent Danish studies, however, point at stress being an increasing problem in knowledge-intensive companies...... with informally, individu-ally and incidentally. It is only when problems exist that enhanced support is offered in order to help an employee to cope or recover. As most workplace initiatives work at this tertiary level, the sources of work-related and organiza-tional stress are not reduced or eliminated...... as good and stimulating, but has on the other hand sides to it which can cause frustration and stress. The implication of organisational characteristics of the knowledge-intensive companies studied is a transfer of the responsibility for ones own working-life. Consequently, issues are dealt...

The methods and models of the indicators of current use in the production have concentrated in the assessment of people's performance as determinative resource of the organizational success in the search for the competitiveness. Associated with the classic indicators of performance assessment of the production proceeding, other indicators are used in the assessment of risks and hazards, however with methods focused in the tasks, without connection with the real work activity. The present article explores literature on the models of performance measurement in use in companies and a field research to understand how companies interpret and use indicators that relate health and work, to direct future studies on the subject. Regarding the literature review, one can see that health indicators can be basically divided into two major groups: the legal and managerial indicators. When conducting case studies, it can be realized that companies do not have precisely the concept of health indicator, or were unable to define which of the indicators could be considered indicators of health, considering that absenteeism was the indicator mentioned by the four companies.

Objectives To determine whether students' previous pharmacy-related work experience was associated with their pharmacy school performance (academic and clinical). Methods The following measures of student academic performance were examined: pharmacy grade point average (GPA), scores on cumulative high-stakes examinations, and advanced pharmacy practice experience (APPE) grades. The quantity and type of pharmacy-related work experience each student performed prior to matriculation was solicited through a student survey instrument. Survey responses were correlated with academic measures, and demographic-based stratified analyses were conducted. Results No significant difference in academic or clinical performance between those students with prior pharmacy experience and those without was identified. Subanalyses by work setting, position type, and substantial pharmacy work experience did not reveal any association with student performance. A relationship was found, however, between age and work experience, ie, older students tended to have more work experience than younger students. Conclusions Prior pharmacy work experience did not affect students' overall academic or clinical performance in pharmacy school. The lack of significant findings may have been due to the inherent practice limitations of nonpharmacist positions, changes in pharmacy education, and the limitations of survey responses.

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

1997-01-01

The present study investigated the relationships between the operator's appraisal of his own work situation and the quality of his own work performance, as well as self-reported errors in a nuclear power plant control room. In all, 98 control room operators from two nuclear power units filled out a questionnaire and several diaries during two operational conditions, annual outage and normal operation. As expected, the operators reported higher work demands in annual outage as compared to normal operation. In response to the increased demands, the operators reported that they used coping strategies such as increased effort, decreased aspiration level for work performance quality, and increased use of delegation of tasks to others. This way of coping does not reflect less positive motivation for the work during the outage period. Instead, the operators maintain the same positive motivation for their work, and succeed in being more alert during morning and night shifts. However, the operators feel less satisfied with their work result. The operators also perceive the risk of making minor errors as increasing during outage. (Author)

The process of recovery from work-related stress, consisting of complaint reduction and work-resumption, is not yet fully understood. The aim of this study was to investigate predictors of complaint reduction and work-resumption, as well as testing complaint reduction as a mediator in the association between predictors and work-resumption. Seventy-one patients on sickness-leave because of work-related stress complaints were followed over a period of 13 months. Predictors comprised personal (demographics, coping, cognitions), work-related (job-characteristics, social support), and illness-related (complaint duration, absence duration) variables. Dependent variables were distress complaints, burnout complaints, and work-resumption. Complaints reduced considerably over time to borderline clinical levels and work-resumption increased to 68% at 13 months. Predictors of stronger reduction of distress complaints were male gender, less working hours, less decision authority, more co-worker support, and shorter absence duration. Predictors of stronger reduction of burnout complaints were male gender, lower age, high education, less avoidant coping, less decision authority, more job security, and more co-worker support. Predictors of work-resumption were lower age and stronger reduction of burnout complaints. No indication for a mediating role of burnout complaints between the predictor age and work-resumption was found. Complaint reduction and work-resumption are relatively independent processes. Symptom reduction is influenced by individual and work-related characteristics, which holds promise for a multidisciplinary treatment approach for work-related stress.

Occupational injury represents 7,7 at 69,9% of the total ocular traumatisms. They can be a major source of visuel loss and blindness. The aim is to study the epidemiology of work-related ocular injuries: objects frequencies,works most exposed. We performed a prospective study that interest 78 patients having a work-related ocular traumatism during a 4 months period. They were admitted at ocular emergeney All patients underwent an ophtalmologic examination completed with orbital radiography and echography. A medical and/or chirurgical appropriate treatment was institued. Occupationnal injury frequency was 9% of the whole ocular traumatisms in the same period. The mean age was 31 years. 55% of cases were under 30 years. 91% were male. Most exposed works were industrial and mecanical sectors In 70,5% of cases work-related eye injuries were caused by projectile objects. Most common lesion was corneal superficial foreign body (58%). Open globe injury was noted in 8%. 95% of patients had no eye protection at the time of the accident. 13% were blind or unilateral partially sighted (according to the OMS classification). The authors discussed the importance and different prevention strategies to prevent the risk of blindness and socio-economical cost of occupationnal accidents. There is a need for systematic periodic sensibilization to reduce these accidents and blindness.

Teacher performance and work environment in the instructional process in vocational school

Teachers should have pedagogical, personality, social, and professional competency. stated that performance appraisal has several benefits, namely for the implementation of reward and punishment system, provision of feedback for teachers to develop their competencies, identification of training needs, and diagnosis of problems. According to performance is one's work result or success rate as a whole over a certain period of time in performing tasks compared to various possibilities, such as work standards, targets or criteria which have been predetermined and agreed. One's performance is based on daily tasks and responsibilities assigned to him/her. The racial differences in personality are largely due to different environmental influences, where people of different races have progressed for generations. Vocational high school teachers have a low pedagogic and professional performance. The factors that influence performance, according to the partner-lawyer model proposed, are expectations about rewards, encouragements, abilities, needs and traits, perceptions of tasks, internal and external rewards, perceptions of reward levels and job satisfaction. This study used a survey method to collect data or information about a large population using relatively small samples. The population of this research was vocational high school teachers. Data analysis techniques used the Regression Analysis with the assistance of SPSS. The results of teacher performance are as follows: 1) the pedagogic performance was relatively good; 2) professional performance was relatively good, and the overall performance of vocational high school teachers was still less effective and efficient; 3) the teachers' work environment was 42.5234%; and 4) there was no correlation between work environment and teacher performance, meaning that the work environment (conditions of physical work environment, psychological work environment, and non-physical work environment) does not positively support the

Contralateral Delay Activity Tracks Fluctuations in Working Memory Performance.

2018-01-08

Neural measures of working memory storage, such as the contralateral delay activity (CDA), are powerful tools in working memory research. CDA amplitude is sensitive to working memory load, reaches an asymptote at known behavioral limits, and predicts individual differences in capacity. An open question, however, is whether neural measures of load also track trial-by-trial fluctuations in performance. Here, we used a whole-report working memory task to test the relationship between CDA amplitude and working memory performance. If working memory failures are due to decision-based errors and retrieval failures, CDA amplitude would not differentiate good and poor performance trials when load is held constant. If failures arise during storage, then CDA amplitude should track both working memory load and trial-by-trial performance. As expected, CDA amplitude tracked load (Experiment 1), reaching an asymptote at three items. In Experiment 2, we tracked fluctuations in trial-by-trial performance. CDA amplitude was larger (more negative) for high-performance trials compared with low-performance trials, suggesting that fluctuations in performance were related to the successful storage of items. During working memory failures, participants oriented their attention to the correct side of the screen (lateralized P1) and maintained covert attention to the correct side during the delay period (lateralized alpha power suppression). Despite the preservation of attentional orienting, we found impairments consistent with an executive attention theory of individual differences in working memory capacity; fluctuations in executive control (indexed by pretrial frontal theta power) may be to blame for storage failures.

Working memory, math performance, and math anxiety.

Ashcraft, Mark H; Krause, Jeremy A

The cognitive literature now shows how critically math performance depends on working memory, for any form of arithmetic and math that involves processes beyond simple memory retrieval. The psychometric literature is also very clear on the global consequences of mathematics anxiety. People who are highly math anxious avoid math: They avoid elective coursework in math, both in high school and college, they avoid college majors that emphasize math, and they avoid career paths that involve math. We go beyond these psychometric relationships to examine the cognitive consequences of math anxiety. We show how performance on a standardized math achievement test varies as a function of math anxiety, and that math anxiety compromises the functioning of working memory. High math anxiety works much like a dual task setting: Preoccupation with one's math fears and anxieties functions like a resource-demanding secondary task. We comment on developmental and educational factors related to math and working memory, and on factors that may contribute to the development of math anxiety.

This study investigated the constraints underlying developmental improvements in complex working memory span performance among 120 children of between 6 and 10 years of age. Independent measures of processing efficiency, storage capacity, rehearsal speed, and basic speed of processing were assessed to determine their contribution to age-related variance in complex span. Results showed that developmental improvements in complex span were driven by 2 age-related but separable factors: 1 associated with general speed of processing and 1 associated with storage ability. In addition, there was an age-related contribution shared between working memory, processing speed, and storage ability that was important for higher level cognition. These results pose a challenge for models of complex span performance that emphasize the importance of processing speed alone.

Previous research has demonstrated that the employee deviance imposes enormous costs on organizational performance and productivity. Similar research supports the positive effect of favorable supervisor feedback on employee job performance. In light of such, it is important to understand the interaction between supervisor feedback environment and employee deviant behavior to streamline organization operations. The purposes of this study were to explore how the supervisor feedback environment influences employee deviance and to examine the mediating role played by work-related stressors. Data were collected from 276 subordinate-supervisor dyads at a regional hospital in Yilan. Structural equation modeling analyses were conducted to test hypotheses. Structural equation modeling analysis results show that supervisor feedback environment negatively related to interpersonal and organizational deviance. Moreover, work-related stressors were found to partially mediate the relationship between supervisor feedback environment and employee deviance. Study findings suggest that when employees (nurses in this case) perceive an appropriate supervisor-provided feedback environment, their deviance is suppressed because of the related reduction in work-related stressors. Thus, to decrease deviant behavior, organizations may foster supervisor integration of disseminated knowledge such as (a) how to improve employees' actual performance, (b) how to effectively clarify expected performance, and (c) how to improve continuous performance feedback. If supervisors absorb this integrated feedback knowledge, they should be in a better position to enhance their own daily interactions with nurses and reduce nurses' work-related stress and, consequently, decrease deviant behavior.

Although we know much about work-related physician burnout and the subsequent negative effects, we do not fully understand work-related physician wellness. Likewise, the relation of wellness and burnout to physician happiness is unclear. The purpose of this study was to examine how physician burnout and wellness contribute to happiness. We sampled 2000 full-time physician members of the American Academy of Family Physicians. Respondents completed a demographics questionnaire, questions about workload, the Physician Wellness Inventory, the Maslach Burnout Inventory, and the Subjective Happiness Scale. We performed a hierarchical regression analysis with the burnout and wellness subscales as predictor variables and physician happiness as the outcome variable. Our response rate was 22%. Career purpose, personal accomplishment, and perception of workload manageability had significant positive correlations with physician happiness. Distress had a significant negative correlation with physician happiness. A sense of career meaning and accomplishment, along with a lack of distress, are important factors in determining physician happiness. The number of hours a physician works is not related to happiness, but the perceived ability to manage workload was significantly related to happiness. Wellness-promotion efforts could focus on assisting physicians with skills to manage the workload by eliminating unnecessary tasks or sharing workload among team members, improving feelings of work accomplishment, improving career satisfaction and meaning, and managing distress related to patient care.

New ways of working (NWW) is a type of work organization that is characterized by temporal and spatial flexibility, often combined with extensive use of information and communication technologies (ICT) and performance-based management. In a three-wave intervention study, we examined the effects of NWW on both the organization of work (changes in control over time and place of work; working hours and work location; and other key job characteristics), and on employees' outcomes (work-nonwork balance; health and well-being; and job-related outcomes). We applied a quasi-experimental design within a large Dutch financial company (N = 2,912). We studied an intervention group (n = 2,391) and made comparisons with a reference group (n = 521). There were three study waves: (i) one/two months before, and (ii) 4 months and (iii) 10 months after implementation of NWW. Repeated measures analyses of covariance (involving 361 participants from the intervention group and 80 participants from the reference group) showed a large and significant shift from hours worked at the office to hours worked at home after implementation of NWW. Accordingly, commuting time was reduced. Employees remained working on week days and during day time. Psychosocial work-characteristics, work-nonwork balance, stress, fatigue, and job-related outcomes remained favourable and largely unaffected, but the health score in the intervention group decreased (medium effect). These findings suggest that the implementation of NWW does not necessarily lead to changes in psychosocial work characteristics, well-being or job-related outcomes.

Abstract Background It is well-known that health care workers in today’s general hospitals have to deal with high levels of job demands, which could have negative effects on their health, well-being, and job performance. A way to reduce job-related stress reactions and to optimize positive work-related outcomes is to raise the level of specific job resources and opportunities to recover from work. However, the question remains how to translate the optimization of the balance between job deman...

Differential working memory correlates for implicit sequence performance in young and older adults.

Bo, Jin; Jennett, S; Seidler, R D

2012-09-01

Our recent work has revealed that visuospatial working memory (VSWM) relates to the rate of explicit motor sequence learning (Bo and Seidler in J Neurophysiol 101:3116-3125, 2009) and implicit sequence performance (Bo et al. in Exp Brain Res 214:73-81, 2011a) in young adults (YA). Although aging has a detrimental impact on many cognitive functions, including working memory, older adults (OA) still rely on their declining working memory resources in an effort to optimize explicit motor sequence learning. Here, we evaluated whether age-related differences in VSWM and/or verbal working memory (VWM) performance relates to implicit performance change in the serial reaction time (SRT) sequence task in OA. Participants performed two computerized working memory tasks adapted from change detection working memory assessments (Luck and Vogel in Nature 390:279-281, 1997), an implicit SRT task and several neuropsychological tests. We found that, although OA exhibited an overall reduction in both VSWM and VWM, both OA and YA showed similar performance in the implicit SRT task. Interestingly, while VSWM and VWM were significantly correlated with each other in YA, there was no correlation between these two working memory scores in OA. In YA, the rate of SRT performance change (exponential fit to the performance curve) was significantly correlated with both VSWM and VWM, while in contrast, OA's performance was only correlated with VWM, and not VSWM. These results demonstrate differential reliance on VSWM and VWM for SRT performance between YA and OA. OA may utilize VWM to maintain optimized performance of second-order conditional sequences.

The olfactory bulb is anatomically exposed and thus can be directly damaged by external stimulation. This can occur as an occupational injury owing to contact with organic solvents or other causes. We present cases of eight patients who sustained occupation-related exposure to potentially toxic substances and later presented with signs and symptoms of anosmia. We examined the occupational and medical characteristics of the patients and evaluated their work-relatedness. Case 1: A 50-year-old man performed high-frequency heat treatments for approximately 11 years. He experienced decreased senses for olfaction and taste during the later years culminating in the diagnosis of anosmia after 3 years (high work-relatedness). Case 2: A 54-year-old man whose work involved exposure to various organic solvents, such as spray painting and application of paint and thinners for approximately 4 years, was subsequently diagnosed with anosmia based on rhinorrhea, headache, and loss of olfaction (high work-relatedness). Case 3: A 44-year-old-man who performed spray painting for approximately 17 years developed anosmia (high work-relatedness). Case 4: A 44-year-old man was involved in ship engine cleaning once a month, for approximately 7 h per cleaning session; he was diagnosed with anosmia based on loss of olfaction (low work-relatedness). Case 5: A 41-year-old man worked in ship building block construction for approximately 13 years; anosmia diagnosis was based on loss of olfaction (low work-relatedness). Case 6: A 47-year-old woman performed product inspection and labeling at a plant manufacturing automobile parts; anosmia diagnosis was based on decreased olfaction and taste (low work-relatedness). Case 7: A 50-year-old woman performed epoxy coating in a plant manufacturing automobile parts; anosmia diagnosis was based on diminishing olfaction (low work-relatedness). Case 8: A 57-year-old woman performed cleaning of the area where mobile phone parts were manufactured

However, voice disorders also present with other symptoms such as difficulty in maintaining the voice (asthenia, vocal fatigue, variation in habitual vocal fundamental frequency, hoarseness, lack of vocal volume and projection, loss of vocal efficiency, and weakness when speaking. There are several proposals for the etiologic classification of dysphonia: functional, organofunctional, organic, and work-related voice disorder (WRVD.OBJECTIVE: To conduct a literature review on WRVD and on the current Brazilian labor legislation.METHODS: This was a review article with bibliographical research conducted on the PubMed and Bireme databases, using the terms "work-related voice disorder", "occupational dysphonia", "dysphonia and labor legislation", and a review of labor and social security relevant laws.CONCLUSION: WRVD is a situation that frequently is listed as a reason for work absenteeism, functional rehabilitation, or for prolonged absence from work. Currently, forensic physicians have no comparative parameters to help with the analysis of vocal disorders. In certain situations WRVD may cause, work disability. This disorder may be labor-related, or be an adjuvant factor to work-related diseases.

Job stress, depression, work performance, and perceptions of supervisors in military personnel.

Recent studies have identified high levels of job stress in military personnel. This study examined the relationship among job stress, depression, work performance, types of stressors, and perceptions about supervisors in military personnel. Eight hundred nine military personnel answered a 43-item survey on work stress, physical and emotional health, work performance, perceptions about leadership, job stressors, and demographics. More than one- quarter (27.4%) of this military population reported suffering from significant job stress. Both the report of work stress and depression were significantly related to impaired work performance, more days of missed work, poorer physical health, and negative perceptions about the abilities of supervisors and commanders. Depression and job stress were significantly and positively related to each other. These results support accumulating data indicating that work stress is a significant occupational health hazard in the routine military work environment. Targeting and eliminating sources of job stress should be a priority for the U.S. military to preserve and protect the mental health of military personnel.

Impact of Age and Hearing Impairment on Work Performance during Long Working Hours.

Based on demographic prognoses, it must be assumed that a greater number of older workers will be found in the future labor market. How to deal with their possible age-related impairments of sensory functions, like hearing impairment and work performance during extended working time, has not been addressed explicitly until now. The study addresses this interplay. The study was performed on two consecutive days after normal working hours. The 55 participants had to "work" in the study at least three additional hours to simulate a situation of long working hours. The tested measures for (job) performance were: general attention, long-term selective attention, concentration, and reaction time. All of the investigated variables were taken at both days of the study (2 × 2 × 2 repeated measurement design). The results show effects for age, the interaction of hearing impairment and time of measurement, and effects of the measurement time. Older participants reacted slower than younger participants did. Furthermore, younger participants reacted more frequently in a correct way. Hearing impairment seems to have a negative impact especially on measures of false reactions, and therefore especially on measurement time 1. The results can be interpreted in a way that hearing-impaired participants are able to compensate their deficits over time.

The aim of this study was to explore the longitudinal relationship between sitting time on a working day and vitality, work performance, presenteeism, and sickness absence. At the start and end of a five-month intervention program at the workplace, as well as 10 months after the intervention, sitting time and work-related outcomes were measured using a standardized self-administered questionnaire and company records. Generalized linear mixed models were used to estimate the longitudinal relationship between sitting time and work-related outcomes, and possible interaction effects over time. A significant and sustainable decrease in sitting time on a working day was observed. Sitting less was significantly related to higher vitality scores, but this effect was marginal (b = -0.0006, P = 0.000). Our finding of significant though marginal associations between sitting time and important work-related outcomes justifies further research.

Recent studies point to work-related stress as an increasing problem for knowledge workers. However, the working life in knowledge-intensive companies is often described as good and stimulating. The aim of this study is to explore the organizational options for preventing work-related problems...... in knowledge work. This calls for a study of the characteristics of knowledge work, stress management interventions and an in-depth analysis of the organizational factors causing frustrations and work-related problems in relation to knowledge work. In a qualitative study, 27 respondents were interviewed....... They represented different stakeholders in five Danish knowledge-intensive companies, which comprised two consultancies and three engineering consulting companies. The study shows that knowledge work comprises a paradox, since the same work-related or organizational issues could be experienced as both...

Energy is emerging as a topic of importance to organizations, yet we have little understanding of how energy can be useful at an interpersonal level toward achieving workplace goals. We present the results of 4 studies aimed at developing, validating, and testing the relational energy construct. In Study 1, we report qualitative insights from 64 individuals about the experience and functioning of relational energy in the workplace. Study 2 draws from 3 employee samples to conduct exploratory and confirmatory factor analyses on a measure of relational energy, differentiating relational energy from related constructs. To test the predictive validity of the new relational energy scale, Study 3 comprises data from employees rating the level of relational energy they experienced during interactions with their leaders in a health services context. Results showed that relational energy employees experienced with their leaders at Time 1 predicted job engagement at Time 2 (1 month later), while controlling for the competing construct of perceived social support. Study 4 shows further differentiation of relational energy from leader-member exchange (LMX), replicates the positive relationship between relational energy (Time 1) and job engagement (Time 2), and shows that relational energy is positively associated with employee job performance (Time 3) through the mechanism of job engagement. We discuss the theoretical implications of our findings and highlight areas for future research. (c) 2016 APA, all rights reserved).

Employment is a vital part of the postdeployment return to civilian life. This study investigated factors associated with employment-related outcomes (employment status, self-reported work performance, and self-reported work satisfaction) among National Guard members returning from Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn deployments. The sample consisted of 1,151 National Guard service members who had returned from overseas deployments approximately six months earlier. Bivariate and multivariable analyses were performed to examine associations between predictors and employment-related outcome variables. Higher-risk alcohol use was associated with reduced odds of being employed as well as with lower ratings of work satisfaction, whereas psychiatric symptom load was associated with lower self-reported work performance and work satisfaction ratings. Perceived social resources were associated with higher self-reported work performance and work satisfaction, whereas better physical functioning was associated with better self-reported work performance. Policy makers and clinicians may need to consider and assess alcohol use among unemployed National Guard members. They may also need to consider psychiatric symptom load and physical functioning among employed service members who perceive poor work performance and have low work satisfaction. Further research is needed on causal links between these predictors and employment outcomes.

This study investigated the distinctiveness between workaholism and work engagement by examining their longitudinal relationships (measurement interval=7 months) with well-being and performance in a sample of 1,967 Japanese employees from various occupations. Based on a previous cross-sectional study (Shimazu & Schaufeli, 2009), we expected that workaholism predicts future unwell-being (i.e., high ill-health and low life satisfaction) and poor job performance, whereas work engagement predicts future well-being (i.e., low ill-health and high life satisfaction) and superior job performance. T1-T2 changes in ill-health, life satisfaction and job performance were measured as residual scores that were then included in the structural equation model. Results showed that workaholism and work engagement were weakly and positively related to each other. In addition, workaholism was related to an increase in ill-health and to a decrease in life satisfaction. In contrast, work engagement was related to a decrease in ill-health and to increases in both life satisfaction and job performance. These findings suggest that workaholism and work engagement are two different kinds of concepts that are oppositely related to well-being and performance.

Technologists working in nuclear medicine (NM) are exposed to higher radiation doses than most other occupationally exposed populations. The aim of this study was to estimate the risk of cancer in NM technologists in relation to work history, procedures performed and radioprotection practices. From the US Radiologic Technologists cohort study, 72 755 radiologic technologists who completed a 2003-2005 questionnaire were followed for cancer mortality through 31 December 2012 and for cancer incidence through completion of a questionnaire in 2012-2013. Multivariable-adjusted models were used to estimate HRs for total cancer incidence and mortality by history of ever performing NM procedures and frequency of performing specific diagnostic or therapeutic NM procedures and associated radiation protection measures by decade. During follow-up (mean=7.5 years), 960 incident cancers and 425 cancer deaths were reported among the 22 360 technologists who worked with NM procedures. We observed no increased risk of cancer incidence (HR 0.96, 95% CI 0.89 to 1.04) or death (HR 1.05, 95% CI 0.93 to 1.19) among workers who ever performed NM procedures. HRs for cancer incidence but not mortality were higher for technologists who began performing therapeutic procedures in 1960 and later compared with the 1950s. Frequency of performing diagnostic or therapeutic NM procedures and use of radioprotection measures were not consistently associated with cancer risk. No clear associations were observed for specific cancers, but results were based on small numbers. Cancer incidence and mortality were not associated with NM work history practices, including greater frequency of procedures performed. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2012-12-01

Full Text Available On defining the connection between job motivation and job satisfaction and between job satisfaction and work performance is still not complete agreement among experts, given the complexity of the phenomena studied. Over time, the relationship between job motivation and job satisfaction has been addressed in many ways in the organizational psychology. The issue of the connection between job satisfaction and work performance is also at least as controversial as the issues mentioned above with respect to these phenomena. Related to this connection, in the literature existed, over time, at least three points of view which held that: job satisfaction leads to work performance; work performance leads to job satisfaction; rewards are involved between job satisfaction and work performance. The paper aim is to present some aspects related to the connection between job motivation, job satisfaction and work performance. The issues presented in this paper lead to the conclusion that in the work process, the connection between job satisfaction and work performance or the connection between job motivation and job satisfaction are not constant or linear connection. These connections should be nuanced interpreted, depending on the conditions of occurrence. These conclusions are based on the results of a survey conducted among enterprises dealing mostly in trade sector, in Romanian Western Region.

An exploration of the relations between external representations and working memory.

Directory of Open Access Journals (Sweden)

Jiajie Zhang

Full Text Available It is commonly hypothesized that external representations serve as memory aids and improve task performance by means of expanding the limited capacity of working memory. However, very few studies have directly examined this memory aid hypothesis. By systematically manipulating how information is available externally versus internally in a sequential number comparison task, three experiments were designed to investigate the relation between external representations and working memory. The experimental results show that when the task requires information from both external representations and working memory, it is the interaction of information from the two sources that determines task performance. In particular, when information from the two sources does not match well, external representations hinder instead of enhance task performance. The study highlights the important role the coordination among different representations plays in distributed cognition. The general relations between external representations and working memory are discussed.

In the assessment of work-related stress it is crucial to find the factors that generate and increase it in order to identify categories of individuals at risk, to plan interventions for prevention, elimination or reduction of risk. The aim of the study is to assess the subjective stress in 68 workers of a large Italian company dealing with human health, through the use of a questionnaire-indicating tool, elaborated by the Italian National Institute for insurance against accidents at work (INAIL) and developed by the Health and Safety Executive (HSE). We studied a final sample of 68 individuals (34 drivers/rescuers and 34 video display unit (VDU) operators). The questionnaire consists of 35 items (divided into six areas) with five possible answers each, that cover working conditions considered potential causes of stress. The drivers/rescuers had a better performance than the VDU operators, especially in the areas "demand", "relationships" and "role". We compared men and women in the two groups, finding that, in VDU operators, women had a better performance than men in all areas, except "role" and "changes", in which the overall scores were the same in men and women. In the drivers/rescuers women showed more critical scores in the items "relationships" and "change". The results show that: the questionnaire-indicating tool is useful, with a demonstrated effectiveness for the occupational physician during the visits and proven validity; additional future efforts should focus on understanding the psycho-social, organizational and individual problems related to stress and the consequent implementation of preventive measures.

Full Text Available Abstract Background It is well-known that health care workers in today’s general hospitals have to deal with high levels of job demands, which could have negative effects on their health, well-being, and job performance. A way to reduce job-related stress reactions and to optimize positive work-related outcomes is to raise the level of specific job resources and opportunities to recover from work. However, the question remains how to translate the optimization of the balance between job demands, job resources, and recovery opportunities into effective workplace interventions. The aim of the DISCovery project is to develop and implement tailored work-oriented interventions to improve health, well-being, and performance of health care personnel. Methods/Design A quasi-experimental field study with a non-equivalent control group pretest-posttest design will be conducted in a top general hospital. Four existing organizational departments will provide both an intervention and a comparison group. Two types of research methods are used: (1 a longitudinal web-based survey study, and (2 a longitudinal daily diary study. After base-line measures of both methods, existing and yet to be developed interventions will be implemented within the experimental groups. Follow-up measurements will be taken one and two years after the base-line measures to analyze short-term and long-term effects of the interventions. Additionally, a process evaluation and a cost-effectiveness analysis will be carried out.

Full Text Available Based on demographic prognoses, it must be assumed that a greater number of older workers will be found in the future labor market. How to deal with their possible age-related impairments of sensory functions, like hearing impairment and work performance during extended working time, has not been addressed explicitly until now. The study addresses this interplay. The study was performed on two consecutive days after normal working hours. The 55 participants had to “work” in the study at least three additional hours to simulate a situation of long working hours. The tested measures for (job performance were: general attention, long-term selective attention, concentration, and reaction time. All of the investigated variables were taken at both days of the study (2 × 2 × 2 repeated measurement design. The results show effects for age, the interaction of hearing impairment and time of measurement, and effects of the measurement time. Older participants reacted slower than younger participants did. Furthermore, younger participants reacted more frequently in a correct way. Hearing impairment seems to have a negative impact especially on measures of false reactions, and therefore especially on measurement time 1. The results can be interpreted in a way that hearing-impaired participants are able to compensate their deficits over time.

The present study investigated the effects of drug cue exposure on working memory performance in cigarette smokers. Adult smokers (N=23) deprived for 12 hr performed a working memory task during which they were exposed to three types of task-irrelevant stimuli: Pictures containing smoking related-content, pictures devoid of smoking content, and a fixation cross. Consistent with prior research, we found that drug cue exposure affected the processing of subsequent items (i.e., carry-over effects). Specifically, we found that working memory performance was worse on trials containing neutral pictures preceded by trials containing smoking cues compared with performance on trials containing neutral pictures preceded by trials not containing smoking-related stimuli. Previously observed effects of smoking cue exposure on cognitive processing were replicated but only after removing trials subject to carry-over effects. These results replicate and extend previous research demonstrating similar effects and highlight the significant methodological and conceptual implications of carry-over effects. PMID:17454718

2015-01-01

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.

National estimates of occupational asthma (OA) in the United States are sparse. Using data from the Third National Health and Nutrition Examination Survey (NHANES III) 1988-1994, we analyzed associations between occupation and work-related asthma and work-related wheezing among U.S. workers. This study identified several occupations that were at risk of developing work-related asthma and/or wheezing, with cleaners and equipment cleaners showing the highest risks. Other major occupations identified were farm and agriculture; entertainment; protective services; construction; mechanics and repairers; textile; fabricators and assemblers; other transportation and material moving occupations; freight, stock, and material movers; and motor vehicle operators. The population attributable risks for work-related asthma and work-related wheezing were 26% and 27%, respectively. This study adds evidence to the literature that identifies work-related asthma as an important public health problem. Several occupations are targeted for additional evaluation and study. Of particular interest are cleaners, which are being increasingly reported as a risk group for asthma. Future intervention strategies need to be developed for effective control and prevention of asthma in the workplace. Copyright 2003 Wiley-Liss, Inc.

Can diabetes be treated as an indirectly work-related disease?

Directory of Open Access Journals (Sweden)

Andrzej Marcinkiewicz

2017-10-01

Full Text Available In this article the authors attempted to analyze the arguments for considering diabetes as a work-related disease. An overview of literature has been done out of articles published in the years 1980–2016, with the use of combination of key words referring to employment, workplace, and diabetes. The PubMed database was the source of data. The authors indicate that the following arguments are in favor of diabetes being recognized as a work-related disease: diabetes is not an occupational disease, it is not directly related to the work environment or the way the work is performed, but there are observed adverse effects of occupational work-related nuisances, such as night shift work, long work hours, job strain or workplace standing time, which influence its development and course. The number of publications on diabetes, including the problem of occupational work is comparable to the number of analogous publications concerning work-related diseases such as hypertension or ischemic heart disease. Moreover, some aspects of professional activity and diabetes were also included in clinical recommendations for the workplace, which is uncommon in the case of other diseases, even those generally recognized as work-related. Data from medical references, indicating the effectiveness of workplace interventions aimed at preventing diabetes development and/or worsening of its course should be considered as an argument for the inclusion of diabetes into the group of work-related diseases. This should also support the need for further research and practical actions aimed at preventing diabetes at the workplace. Med Pr 2017;68(5:667–675

Teaching is considered a highly stressful occupation, with work-related stress levels among teachers being among the highest compared to other professions. Unfortunately there are very few studies regarding the levels of work-related stress among teachers in the Republic of Macedonia. To identify the level of self-perceived work-related stress among teachers in elementary schools and its relationship to gender, age, position in the workplace, the level of education and working experience. We performed a descriptive-analytical model of a cross-sectional study that involved 300 teachers employed in nine elementary schools. Evaluation of examined subjects included completion of a specially designed questionnaire. We found that the majority of interviewed teachers perceive their work-related stress as moderate. The level of work-related stress was significantly high related to the gender, age, position in workplace, as well as working experience (p related to level of education (p stressful as compared to the upper-grade teachers (18.5% vs. 5.45%), while the same is true for female respondents as compared to the male ones (15.38% vs. 3.8%). In addition, our results show that teachers with university education significantly more often associate their workplace with stronger stress than their colleagues with high education (13.48% vs. 9.4%). We also found that there is no significant difference of stress levels between new and more experienced teachers. Our findings confirm that the majority of interviewed teachers perceived their work-related stress as high or very high. In terms of the relationship between the level of teachers' stress and certain demographic and job characteristics, according to our results, the level of work-related stress has shown significantly high relation to gender, age, levels of grades taught as well as working experience, and significant relation to the level of education.

2015-02-01

This study investigated the distinctiveness of two types of heavy work investment (i.e., workaholism and work engagement) by examining their 2-year longitudinal relationships with employee well-being and job performance. Based on a previous cross-sectional study by Shimazu and Schaufeli (Ind Health 47:495-502, 2009) and a shorter term longitudinal study by Shimazu et al. (Ind Health 50:316-21, 2012; measurement interval = 7 months), we predicted that workaholism predicts long-term future unwell-being (i.e., high ill-health and low life satisfaction) and poor job performance, whereas work engagement predicts future well-being (i.e., low ill-health and high life satisfaction) and superior job performance. A two-wave survey was conducted among employees from one Japanese company, and valid data from 1,196 employees was analyzed using structural equation modeling. T1-T2 changes in ill-health, life satisfaction, and job performance were measured as residual scores, which were included in the structural equation model. Workaholism and work engagement were weakly and positively related to each other. In addition, and as expected, workaholism was related to an increase in ill-health and to a decrease in life satisfaction. In contrast, and also as expected, work engagement was related to increases in both life satisfaction and job performance and to a decrease in ill-health. Although workaholism and work engagement are weakly positively related, they constitute two different concepts. More specifically, workaholism has negative consequences across an extended period of 2 years, whereas work engagement has positive consequences in terms of well-being and performance. Hence, workaholism should be prevented and work engagement should be stimulated.

To investigate the associations between midlife work-related stress and late-life cognition in individuals without dementia from the general population. The Cardiovascular Risk Factors, Aging and Dementia (CAIDE) study population (n = 2000) was randomly selected from independent Finnish population-based surveys (baseline mean age 50 years). Participants underwent two re-examinations in late life (mean age 71 and 78 years, respectively). 1511 subjects participated in at least one re-examination (mean total follow-up 25 years). Work-related stress was measured using two questions on work demands administered in midlife. Multiple cognitive domains were assessed. Analyses were adjusted for several potential confounders. Higher levels of midlife work-related stress were associated with poorer performance on global cognition [β-coefficient, -0.02; 95% confidence interval (CI), -0.05 to -0.00], and processing speed [β -0.03, CI -0.05 to -0.01]. Results remained significant after adjusting for potential confounders. Work-related stress was not significantly associated with episodic memory, executive functioning, verbal fluency or manual dexterity. This study shows that global cognition and processing speed may be particularly susceptible to the effects of midlife work-related stress.

Research purpose: The objective of this study was to investigate whether job stress and coping strategies could predict the work-related well-being (burnout and work engagement of hospital pharmacists in South Africa. Motivation for the study: Information about the work-related well-being and coping strategies of hospital pharmacists could be used to plan individual and organisational interventions which can be used to retain them and to manage their well-being and performance. Research design, approach and method: A survey design was used. A stratified random sample (N = 187 of pharmacists in South African hospitals was studied. The Maslach Burnout Inventory – Human Services Survey, Utrecht Work Engagement Scale, Pharmacist Stress Inventory and the COPE questionnaire were administered. Main findings: The results showed that job related stress and three coping strategies (approach coping, avoidant coping, and turning to religion predicted burnout and work engagement of South African hospital pharmacists. Practical implications: Job stressors that are in the main responsible for the unfavourable work environment and that lead to the development of burnout amongst hospital pharmacists should be addressed. It is also important to enhance the coping capabilities of the hospital pharmacists. Contribution/value-add: The findings of this study provide insight into the factors impacting on the work-related well-being of hospital pharmacists in South Africa.

To examine radiologists' screening performance in relation to the number of diagnostic work-ups performed after abnormal findings are discovered at screening mammography by the same radiologist or by different radiologists. In an institutional review board-approved HIPAA-compliant study, the authors linked 651 671 screening mammograms interpreted from 2002 to 2006 by 96 radiologists in the Breast Cancer Surveillance Consortium to cancer registries (standard of reference) to evaluate the performance of screening mammography (sensitivity, false-positive rate [ FPR false-positive rate ], and cancer detection rate [ CDR cancer detection rate ]). Logistic regression was used to assess the association between the volume of recalled screening mammograms ("own" mammograms, where the radiologist who interpreted the diagnostic image was the same radiologist who had interpreted the screening image, and "any" mammograms, where the radiologist who interpreted the diagnostic image may or may not have been the radiologist who interpreted the screening image) and screening performance and whether the association between total annual volume and performance differed according to the volume of diagnostic work-up. Annually, 38% of radiologists performed the diagnostic work-up for 25 or fewer of their own recalled screening mammograms, 24% performed the work-up for 0-50, and 39% performed the work-up for more than 50. For the work-up of recalled screening mammograms from any radiologist, 24% of radiologists performed the work-up for 0-50 mammograms, 32% performed the work-up for 51-125, and 44% performed the work-up for more than 125.

Employment offers many benefits to people with mental illness, yet their employment rate is much lower than that of the general population. We investigated the effect of work-related motor skills, neurocognition, and job attitudes on the work performance of people with mental illness, comparing those working in sheltered workshops, with controls working in similar jobs. Twenty-nine adults with severe mental illness and 27 controls matched by gender and age were enrolled into the study using convenience sampling. They were assessed for gross and fine motor hand functioning, job attitudes, work performance, and cognition. People with mental illness scored lower on work performance, cognitive functioning, and hand dexterity while sitting and working with tools. They were assigned lower job loads than were controls, and perceived the physical environment at work as more constraining than did controls. Assembling motor skills significantly explained the work performance of people with mental illness. The results expand our understanding of the complexities involved in the employment of people with severe mental illness, and point to new paths for improving vocational outcomes of people with severe mental illness, taking into account their motor skills and job attitudes. Implications for rehabilitation Therapists should be aware that employed people with severe mental illness may have various unmet needs, affecting their work performance and experience of stress. This study results demonstrate importance of motor skills and perception of the work environment for the promotion of vocational outcomes among individuals with severe mental illness. Employment of people with severe mental illness should be viewed from holistic perspective as with general population, rather than focused on traditionally illness-related factors.

To examine the associations of age, lifestyle and work-related factors, and particularly work engagement with the work ability index (WAI) and its sub-dimensions. Step-wise regression analysis with a sample of Finnish firefighters (n = 403) was used. The outcome variables were the WAI and its six sub-dimensions. The independent variables consisted of age, lifestyle variables (alcohol consumption, BMI, smoking, physical exercise, and sleep problems), working conditions (job demands, physical workload, supervisory relations, and task resources), and work engagement. The outcome variables and all the variables related to lifestyle, working conditions, and work engagement were measured in 2009. Work ability at baseline 10 years earlier was adjusted for in the models. Work engagement, age, physical exercise, sleep problems, and physical workload were associated with the WAI. All independent variables, except BMI and alcohol consumption, were associated with at least one sub-dimension of the WAI after controlling the baseline WAI. Lifestyle variables, working conditions, and work engagement were more strongly related to the subjective WAI sub-dimensions than to the two more objective WAI sub-dimensions. Work engagement was significantly associated with work ability even after adjusting for various factors, indicating its importance in promoting work ability. Other key factors for good work ability were frequent exercise, good sleep, non-smoking, low job demands, low physical workload, and high task resources. More specifically, this study suggests that in maintaining work ability, it is valuable not only to promote lifestyle factors or working conditions, but also to enhance employees' positive state of work engagement.

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

This prospective study shows that working performance, quality of life (QoL), and quality of hearing (QoH) are better with two compared with a single cochlear implant (CI). The impact of the second CI on the patient's QoL is as significant as the impact of the first CI. To evaluate the benefits of sequential bilateral cochlear implantation in working, QoL, and QoH. We studied working performance, work-related stress, QoL, and QoH with specific questionnaires in 15 patients with unilateral CI scheduled for sequential CI of another ear. Sound localization performance and speech perception in noise were measured with specific tests. All questionnaires and tests were performed before the second CI surgery and 6 and 12 months after its activation. Bilateral CIs increased patients' working performance and their work-related stress and fatigue decreased. Communication with co-workers was easier and patients were more active in their working environment. Sequential bilateral cochlear implantation improved QoL, QoH, sound localization, and speech perception in noise statistically significantly.

Informal eldercare and work-related strain.

In light of an aging workforce, reconciling informal eldercare and paid work becomes increasingly pertinent. This article investigates the association between informal eldercare and work-related strain and tests for both the "competing demands" and "expansion" hypotheses. The sample of 938 Austrian employees consisted of employees caring for older relatives and a control group of employees without eldercare obligations. We ran a Tobit regression model on work-related strain with different measures of informal eldercare as explanatory variables and controls for both personal and workplace characteristics. Accounting for different characteristics of eldercare within one estimation model revealed that informal eldercare was associated with work-related strain in 2 ways, that is, it increased with both care hours and subjective care burden. However, after controlling for these burdensome attributes of eldercare, the carer status as such was found to be negatively associated with work-related strain. In addition and independently of care commitments, work-related factors, such as advanced skills and job motivation, reduced work-related strain. This article lends support to both the "competing demands" and the "expansion" hypotheses. Commitment to eldercare can enhance work-related outcomes but entails work-related problems if care burden and time demands of eldercare are substantial. Thus, workers with eldercare responsibilities cannot be considered less productive from the outset. An individual assessment of their situation, considering the care and work setting, is required. Findings from this study support the design of workplace initiatives to uphold workers' productivity in general and bring specific attention to policies alleviating workers' eldercare burden.

Marques-Quinteiro, Pedro; Curral, Luís Alberto

2012-01-01

This article explores the relationship between goal orientation, self-leadership dimensions, and adaptive and proactive work role performances. The authors hypothesize that learning orientation, in contrast to performance orientation, positively predicts proactive and adaptive work role performances and that this relationship is mediated by self-leadership behavior-focused strategies. It is posited that self-leadership natural reward strategies and thought pattern strategies are expected to moderate this relationship. Workers (N = 108) from a software company participated in this study. As expected, learning orientation did predict adaptive and proactive work role performance. Moreover, in the relationship between learning orientation and proactive work role performance through self-leadership behavior-focused strategies, a moderated mediation effect was found for self-leadership natural reward and thought pattern strategies. In the end, the authors discuss the results and implications are discussed and future research directions are proposed.

Full Text Available Background and aimsShift work is a major feature of working life that affects diverse aspects of human life. The main purposes of this study were to investigate shift work-related health problems and their risk factors among workers of "12-hour shift" schedule.MethodsThis cross-sectional study was carried out at 8 petrochemical industries in Asalooyeh area. Study population consisted of 1203 workers including 549 shift worker (46% and 654 day worker (54%. Data on personal details, shift schedule and adverse effects of shift work werecollected by anonymous questionnaire. Statistical analyses were performed using SPSS, version 11.5. The level of significance was set at 5%.ResultsAlthough, the results showed that health problems among shift workers was more prevalent than day workers, but the differences were just significant in gastrointestinal and musculoskeletal disorders (p<0.05. Multiple linear regressions indicated that in addition to shift working, other variants such as long work hours, type of employment, second job, number of children and job title were associated with health problems.ConclusionPrevalence rates of gastrointestinal and musculoskeletal problems among shift workers were significantly higher than that of day workers. Although, working in shift system was the main significant factor associated with the reported problems, but other demographic andwork variables were also found to have association.

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

Working in an Intensive Care Unit (ICU) is increasingly complex and is also physically, cognitively and emotionally demanding. Although the negative emotions of work-related stress have been well studied, the opposite perspective of work engagement might also provide valuable insight into how these emotional demands may be countered. This study focused on the work engagement of ICU professionals and explored the complex relationship between work engagement, job demands and advantageous personal resources. This was a cross-sectional survey study among ICU professionals in a single-centre university hospital. Work engagement was measured by the Utrecht Work Engagement Scale, which included items about opinions related to the respondent's work environment. Additionally, 14 items based on the Jefferson Scale of Physician Empathy were included to measure empathic ability. A digital link to the questionnaire was sent in October 2015 to a population of 262 ICU nurses and 53 intensivists. The overall response rate was 61% (n=193). Work engagement was negatively related both to cognitive demands among intensivists and to emotional demands among ICU nurses. No significant relationship was found between work engagement and empathic ability; however, agreeableness, conscientiousness, and emotional stability were highly correlated with work engagement. Only the number of hours worked per week remained as a confounding factor, with a negative effect of workload on work engagement after controlling for the effect of weekly working hours. Work engagement counterbalances work-related stress reactions. The relatively high workload in ICUs, coupled with an especially heavy emotional burden, may be acknowledged as an integral part of ICU work. This workload does not affect the level of work engagement, which was high for both intensivists and nurses despite the known high job demands. Specific factors that contribute to a healthy and successful work life among ICU professionals need

To quantify the occurrence of deaths directly associated with urban violence among fatal work-related accidents. Verbal autopsies were performed with the relatives and coworkers of residents of Campinas, state of São Paulo, Brazil, who died from external causes in 2015. We have also analyzed police reports and reports of the Legal Medical Institute related to these deaths. We have identified 82 fatal work-related accidents in Campinas in 2015, of which 25 were murders, 35 were traffic accidents not directly related to work activities, and three were suicides at work. The proportional mortality rate for homicides, traffic accidents, and suicides among fatal work-related accidents was estimated at 30.5%, 42.7%, and 3.7%, respectively. Urban violence accounted for three-fourths of the fatal work-related accidents recorded in the period studied.

Astigmatism is an important refractive condition in children. However, the functional impact of uncorrected astigmatism in this population is not well established, particularly with regard to academic performance. This study investigated the impact of simulated bilateral astigmatism on academic-related tasks before and after sustained near work in children. Twenty visually normal children (mean age: 10.8 ± 0.7 years; six males and 14 females) completed a range of standardised academic-related tests with and without 1.50 D of simulated bilateral astigmatism (with both academic-related tests and the visual condition administered in a randomised order). The simulated astigmatism was induced using a positive cylindrical lens while maintaining a plano spherical equivalent. Performance was assessed before and after 20 min of sustained near work, during two separate testing sessions. Academic-related measures included a standardised reading test (the Neale Analysis of Reading Ability), visual information processing tests (Coding and Symbol Search subtests from the Wechsler Intelligence Scale for Children) and a reading-related eye movement test (the Developmental Eye Movement test). Each participant was systematically assigned either with-the-rule (WTR, axis 180°) or against-the-rule (ATR, axis 90°) simulated astigmatism to evaluate the influence of axis orientation on any decrements in performance. Reading, visual information processing and reading-related eye movement performance were all significantly impaired by both simulated bilateral astigmatism (p  0.05). Simulated astigmatism led to a reduction of between 5% and 12% in performance across the academic-related outcome measures, but there was no significant effect of the axis (WTR or ATR) of astigmatism (p > 0.05). Simulated bilateral astigmatism impaired children's performance on a range of academic-related outcome measures irrespective of the orientation of the astigmatism. These findings have

To assess the impact of work-related musculoskeletal disorders (WRMDs) on work ability among workers. A total of 1686 workers in various occupations, such as administration and education, were enrolled as subjects using the random cluster sampling method. The WRMDs and work ability of all subjects were evaluated using standardized Nordic questionnaires for the analysis of musculoskeletal symptoms and the Work Ability Index (WAI) scale, respectively. Comparison of work ability and its classification between the disease group and the non-disease group was performed by paired t test, RxC table χ2 test, and the Wilcoxon rank-sum test. The relationship between work duration and work ability was analyzed by the Spearman correlation test and a multi-level model. (1). The work ability of workers in the disease group was significantly lower than that in the non-disease group (Pwork ability between workers with different work durations (work duration, the work ability of workers declined in both groups, and the work ability of workers in the disease group (Spearman coefficient rs=-0. 172, Pfactors for the decrease in work ability among workers.

Exposure to Psychological Aggression at Work and Job Performance: The Mediating Role of Job Attitudes and Personal Health.

Science.gov (United States)

Schat, Aaron; Frone, Michael R

2011-01-01

Despite the growing literature on workplace aggression and the importance of employee performance at work, few studies have examined the relation between workplace aggression and job performance. The purpose of this study was to investigate the relations between psychological aggression at work and two forms of job performance (task performance and contextual performance) and potential mediators of these relations. Based on Conservation of Resources theory and prior research, a model was developed and tested in which overall job attitudes (i.e., job satisfaction and organizational commitment) and overall personal health (i.e., physical and psychological health) fully mediate the relations between exposure to psychological aggression at work and both task performance and contextual performance. Data were obtained from a national probability sample of US workers (N = 2376) and the model was tested using structural equation modelling. The results supported the hypothesized model, demonstrating that exposure to psychological aggression at work negatively predicted both task performance and contextual performance, and that these relations were explained by decrements in job attitudes and health associated with exposure to psychological aggression at work.

The School-to-Work (STW) Opportunities Act was passed to aid students in transitioning from education to employment by offering work-based learning opportunities. In the United States, 72% of high schools offer work-based learning opportunities for credit. This is the first study to describe school performance and school-based behaviors among students enrolled in STW programs and compare them with nonworking and other-working students. In 2003, a questionnaire was administered to five school districts and one large urban school in Wisconsin. Between 2008 and 2010, analyses were completed to characterize STW students and compare them with other students. Of the 6,519 students aged 14-18 years included in the analyses, 461 were involved in an STW program (7%), 3,108 were non-working (48%), and 2,950 were other-working students (45%). Compared with other students, STW students were less likely to have a grade point average >2.0, more likely to have three or more unexcused absences from school, and more likely to spend performance. School-to-Work students reported poorer academic performance and more unhealthy school-related behaviors compared with nonworking students and other-working students. Whereas many factors have a role in why students perform poorly in school, more research on students enrolled in STW programs is needed to understand whether participating has a negative impact on students' academic achievement.

2017-08-01

The impacts of neoliberal or market-based social security reforms in health have been extensively studied. How such reforms transformed employment-related insurance and entitlements, however, has received significantly less attention. This study aims to understand how the employment insurance system operates in Colombia and to assess how the experience of workers seeking social security entitlements relates to the system's structure. We conducted an ethnographic study of the Colombian Occupational Risk System between May 2014 and March 2016, with two main components: 1) analysis of the system itself through in-depth interviews with 32 people working in leadership positions and a systematic review of the system's most important legislation, and 2) a study of people who experienced problems receiving entitlements and were challenging the assessment of their work-related illness or accident. We conducted in-depth interviews with 22 people, followed up with half of them, and reviewed their case files. We found that difficulties accessing health care services, payments for medical leave, job reassignments, severance packages, and filing for pension benefits were common to all cases and resulted from overwhelming bureaucratic and administrative demands. Regional and national evaluation bodies dictate whether a given illness or accident is work-related, and establish a percentage of Loss of Wage Earning Capacity (LWEC). People's disabled bodies rarely reached the threshold of 50% LWEC to qualify for disability pensions. The lengthy process that workers were forced to endure to obtain work-related entitlements always involved the judiciary. The three competing for-profit financial sectors (health insurance, pension funds, and Occupational Risk Administrators) actively challenged workers' demands in order to increase their profits. We conclude that these for-profit sectors work contrary to the principles that sustain social security. Indeed, they push sick and disabled

An abundance of research shows the benefits of participation in volunteer work for individuals, employers and the society as a whole. However, relatively little is known about the precursors of volunteer work. In this study, we aim to fill this gap by investigating to what extent work-related well-being can function as a driver of volunteer work. Moreover, building on the Conservations of Resources Theory (Hobfoll,), we propose that the relationship between work-related well-being (burnout an...

Abstract This article introduces key concepts of work-related stress relevant to the clinical and research fields of psychosomatic medicine. Stress is a term used to describe the body's physiological and/or psychological reaction to circumstances that require behavioral adjustment. According to the Japanese National Survey of Health, the most frequent stressors are work-related problems, followed by health-related and then financial problems. Conceptually, work-related stress includes a varie...

Human resource shortages and reforms in HIV-related care make it challenging for frontline health care providers in southern Africa to deliver high-quality services. At health facilities of the Zambian Defence Forces, a performance and quality improvement approach was implemented to improve HIV-related care and was evaluated in 2010/2011. Changes in providers' work environment and perceived quality of HIV-related care were assessed to complement data of provider performance. The intervention involved on-site training, supportive supervision, and action planning focusing on detailed service delivery standards. The quasi-experimental evaluation collected pre- and post-intervention data from eight intervention and comparison facilities matched on defence force branch and baseline client volume. Overall, 101 providers responded to a 24-item questionnaire on the work environment, covering topics of drugs, supplies, and equipment; training, feedback, and supervision; compensation; staffing; safety; fulfilment; and HIV services quality. In bivariate analysis and multivariate analyses, we assessed changes within each study group and between the two groups. In the bivariate analysis, the intervention group providers reported improvements in the work environment on adequacy of equipment, feeling safe from harm, confidence in clinical skills, and reduced isolation, while the comparison group reported worsening of the work environment on supplies, training, safety, and departmental morale.In the multivariate analysis, the intervention group's improvement and the comparison group's decline were significant on perceived adequacy of drugs, supplies, and equipment; constructive feedback received from supervisor and co-workers; and feeling safe from physical harm (all P equipment). Further, the item "provider lacks confidence in some clinical skills" declined in the intervention group but increased in the comparison group (P = -0.005). In multivariate analysis, changes in perceived

(Progoulaki & Roe 2011). This challenges social capital on board, i.e. the resources inherent in network cooperation associated with norms of reciprocity and trust (Putnam 2000: 19). Fragmentizing ‘blue’ social capital should however be restored, because work performance depends on the quality of cooperation...... findings suggest that a balance between three types of social capital – bonding, bridging and linking – is needed to achieve a high-performance work system (Gittell et al. 2010). Hence, main actors within the shipping sector should take ‘blue’ social capital into account in order to increase work...... efficiency and economic performance....

Age-related differences in working memory updating components.

Science.gov (United States)

Linares, Rocío; Bajo, M Teresa; Pelegrina, Santiago

2016-07-01

The aim of this study was to investigate possible age-related changes throughout childhood and adolescence in different component processes of working memory updating (WMU): retrieval, transformation, and substitution. A set of numerical WMU tasks was administered to four age groups (8-, 11-, 14-, and 21-year-olds). To isolate the effect of each of the WMU components, participants performed different versions of a task that included different combinations of the WMU components. The results showed an expected overall decrease in response times and an increase in accuracy performance with age. Most important, specific age-related changes in the retrieval component were found, demonstrating that the effect of retrieval on accuracy was larger in children than in adolescents or young adults. These findings indicate that the availability of representations from outside the focus of attention may change with age. Thus, the retrieval component of updating could contribute to the age-related changes observed in the performance of many updating tasks. Copyright © 2016 Elsevier Inc. All rights reserved.

2016-01-01

Working memory is an executive memory process that allows transitional information to be held and manipulated temporarily in memory stores before being forgotten or encoded into long-term memory. Working memory is necessary for everyday decision-making and problem solving, making it a fundamental process in the daily lives of older adults. Working memory relies heavily on frontal lobe structures and is known to decline with age. The current study aimed to determine the neural correlates of decreased working memory performance in the frontal lobes by comparing cortical thickness and cortical surface area from two demographically matched groups of healthy older adults, free from cognitive impairment, with high versus low N-Back working memory performance ( N = 56; average age = 70.29 ± 10.64). High-resolution structural T1-weighted images (1 mm isotropic voxels) were obtained on a 3T Philips MRI scanner. When compared to high performers, low performers exhibited significantly decreased cortical surface area in three frontal lobe regions lateralized to the right hemisphere: medial orbital frontal gyrus, inferior frontal gyrus, and superior frontal gyrus (FDR p frontal regions may underlie age-related decline of working memory function.

The effects of fatigue on performance in simulated nursing work.

Science.gov (United States)

Barker, Linsey M; Nussbaum, Maury A

2011-09-01

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

Vahle-Hinz, Tim

2016-10-01

In nonregular forms of employment, such as fixed-term or temporary agency work, 2 sources of stress must be distinguished: task-related stress components (e.g., time pressure) and employment-related stress components (e.g., effort to maintain employment). The present study investigated the relationship between task- and employment-related demands and resources and indicators of strain, well-being, work engagement, and self-rated performance in a sample of nonregular employed workers. Using a 2-wave longitudinal design, the results of autoregressive cross-lagged structural equation models demonstrated that time pressure, as a task-related demand, is positively related to strain and negatively related to well-being and self-rated performance. Autonomy, as a task-related resource, exhibited no significant relationships in the current study. Employment-related demands exhibited negative relationships with well-being and work engagement as well as negative and positive relationships with self-rated performance over time. Employment-related resources were primarily positive predictors of well-being and self-rated performance. Fit indices of comparative models indicated that reciprocal effect models (which enable causal and reverse effects) best fit the data. Accordingly, demands and resources predicted strain, well-being, work engagement, and self-rated performance over time and vice versa. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

2014-01-01

Work-related stress has become one of the major problems in working societies and it increases employees' risk of disease. Its importance has been emphasized also due to its' great socio-economic consequences. Different stress management and worksite interventions have been implemented, however, the actual practices in companies have been assessed little. The purpose of this study was to examine how enterprises in Finland manage work-related stress. An assessment of work-related stress methods was conducted in 40 enterprises acting in the metropolitan area of Finland in May 2010 by a questionnaire. The concept of work-related stress was well known by participants. Enterprises rarely had their own work-related stress management protocol even though all of the workplaces had experienced work-related stress at some point. The collaboration between the workplace and occupational health services varied. Companies easily placed the responsibility for work-related stress assessment and handling on occupational health services. Workplaces have to pay more attention to work-related stress and related issues. The easiest way to do this is to collaborate with occupational health services. Protocols for collaboration should be developed jointly using the available models which have been established as cost-effective.

Persons with Mild Cognitive Impairment (MCI) can experience deficits in working memory. In the present study, we investigated working memory in persons with MCI and cognitively healthy older adults using event-related potentials (ERPs). Participants performed an n-back working memory task with baseline (0-back), low load (1-back), and high load (2-back) working memory conditions. MCI participants' performance was less accurate than that of healthy older adults in both the 1-back and 2-back conditions, and reaction times were longer in MCI than control participants in the 0-back, 1-back and 2-back conditions. ERP analyses revealed delayed P200 and N200 latencies and smaller P300 amplitudes in MCI relative to control participants in the 0-back, 1-back and 2-back conditions. Deterioration in working memory performance concomitant with marked electrophysiological alterations suggests that persons with MCI exhibit deficits in several cognitive processes that include early attention, stimulus discrimination and classification, and updating and manipulation of information held in working memory.

In the current study, we explored how a person's physiological arousal relates to their performance in a challenging math situation as a function of individual differences in working memory (WM) capacity and math-anxiety. Participants completed demanding math problems before and after which salivary cortisol, an index of arousal, was measured. The performance of lower WM individuals did not depend on cortisol concentration or math-anxiety. For higher WM individuals high in math-anxiety, the higher their concentration of salivary cortisol following the math task, the worse their performance. In contrast, for higher WM individuals lower in math-anxiety, the higher their salivary cortisol concentrations, the better their performance. For individuals who have the capacity to perform at a high-level (higher WMs), whether physiological arousal will lead an individual to choke or thrive depends on math-anxiety. 2011 APA, all rights reserved

Work-related problems, many of which could be prevented with proper ergonomic techniques are particularly common in developing countries. The aim of this study was to evaluate the work stress and the development of the work-related musculoskeletal disorders (WRMSDs) of workers employed in the jute mills of India. About 219 male workers engaged in different departments of three jute industries in 24-Parganas (North) and Hooghly districts of West Bengal, India volunteered for this study. Questionnaires along with direct observation of work postures were conducted. Physical parameters such as body weight, height; physiological parameters like heart rate response, blood pressure and psycho-physiological parameters such as perceived exertion rating were studied during different tasks performed by them. It was observed that the 'hacklers' are mostly stressed. Analyses of working postures (OWAS) suggested that their adopted awkward postures were very stressful. A large number of hacklers (92.5% suffer from intense pain in different body parts as compared to workers in other departments of the jute industries. Workers report that the pain even lasts many hours after work. Since most of the workers perform repetitive tasks, so both the workplace as well as the work-rest schedule must be reorganized.

Work-related musculoskeletal diseases (MSD) are disorders in the musculoskeletal structures caused by chronic occupational processes. The objective of this study was to get to know scientific papers on MSD related to the nursing profession. A bibliographic research of the last ten years was conducted at Health Virtual Library using the main data bases. Twenty-one summaries were found. Among them, thirteen were selected because they specifically focused on the subject. Three main areas were identified: occupational health nurses in relation to MSDs--their importance in health prevention and promotion; Ergonomics as MSDs prevention method: performed as changes on work consider risk factors; Vulnerability of Nursing staff to MSDs--predisposing factors to disease caused by inappropriate working conditions. The conclusion was that an occupational and ergonomic health service is important to prevent MSDs, especially among the nursing staff.

A relationship between working memory impairment, disordered neuronal oscillations, and abnormal prefrontal GABA function has been hypothesized in schizophrenia; however, in vivo GABA measurements and gamma band neural synchrony have not yet been compared in schizophrenia. This case-control pilot study (N = 24) compared baseline and working memory task-induced neuronal oscillations acquired with high-density electroencephalograms (EEGs) to GABA levels measured in vivo with magnetic resonance spectroscopy. Working memory performance, baseline GABA level in the left dorsolateral prefrontal cortex (DLPFC), and measures of gamma oscillations from EEGs at baseline and during a working memory task were obtained. A major limitation of this study is a relatively small sample size for several analyses due to the integration of diverse methodologies and participant compliance. Working memory performance was significantly lower for patients than for controls. During the working memory task, patients (n = 7) had significantly lower amplitudes in gamma oscillations than controls (n = 9). However, both at rest and across working memory stages, there were significant correlations between gamma oscillation amplitude and left DLPFC GABA level. Peak gamma frequency during the encoding stage of the working memory task (n = 16) significantly correlated with GABA level and working memory performance. Despite gamma band amplitude deficits in patients across working memory stages, both baseline and working memory-induced gamma oscillations showed strong dependence on baseline GABA levels in patients and controls. These findings suggest a critical role for GABA function in gamma band oscillations, even under conditions of system and cognitive impairments as seen in schizophrenia.

The aim of this research was to analyze the changes that have affected work-related road accidents between 1997 and 2006, using police data. The study focused on drivers aged between 14 and 64 years. The characteristics considered were the age, gender, type of vehicle and occupation of the individuals involved and the location, time and severity of the accident. Two periods were compared, 1997-2000 and 2003-2006. Three types of journey were considered: while at work, commuting (going to and from work), and non-work-related. The percentage of all accidents which were work-related varied little over the decade (10% while at work and 18% while commuting). The accidents that occurred while at work still had the lowest fatality rates (1.4% among women and 3.4% among men in 2003-2006). Men accounted for the majority of the casualties: 90% of fatalities while at work and approximately 80% for the other types of journey. The greatest reduction took place in the number of motorists, and this has led to an increase in the proportion of motorized two-wheelers both while at work and while commuting. In the case of accidents while at work, the professional drivers still had the highest risk, craftsmen and shopkeepers were also at higher risk than manual workers of both genders and male employees. Extending analysis of this type to other European countries would be of major interest both for epidemiological monitoring and the prevention of occupational road accidents.

2011-05-01

Depression is reported to be a major cause of illness-related sub-optimal work performance (presenteeism). However, the majority of studies examining presenteeism have relied on self-report measures of work performance. Furthermore, employers currently face a number of practical challenges in attempting to facilitate early identification of depression. To test whether a web-based screening tool for depression could be used successfully in the workplace and whether it was possible to detect an association between rates of depression and objective measures of impaired workgroup performance. All permanent employees of a telecommunications company with UK-based call centres were encouraged to complete a web-based psychological assessment using the Patient Health Questionnaire depression scale (PHQ-9). In addition to confidential individual level results, the tool was able to provide anonymized summary statistics for each workgroup. Four objective measures of work performance were collected for each workgroup. During the study period, 1161 web-based PHQ-9 questionnaires were completed. There was a negative linear relationship between rates of depressive symptoms and the overall performance of a workgroup (P balance, percent of temporary staff, employees' perceived level of engagement and satisfaction with their line manager (P work setting.

Issues of work intensity, pace, and sustainability in relation to work context and nutritional status.

Panter-Brick, Catherine

2003-01-01

This article raises issues about work intensity, pace, and sustainability during physical activity, focusing attention on the nature of work in labor-intensive societies, the management of exertion in habitual tasks, and the health and broad socioeconomic correlates of alternative ways to regulate work patterns. At the heart of this review are concerns to document human adaptability (in terms of the physical and behavioral management of heavy work) and to renew debate regarding the conceptualization and measurement of work intensity (variously evaluated in absolute or relative terms, as indexed by oxygen consumption, energy expenditure, percentage maximal work capacity, heart rate elevation, time and motion indicators, or physiological cost). Three questions are examined: Is heavy work primarily a matter of time or energy intensity? How is heavy work habitually sustained? What is the bigger picture relating work performance to work context and to nutritional or health status? It is argued that many arduous activities, such as carrying loads, demand endurance over time rather than intensive effort per unit time, and that work pace management lies in regulating both the rate of work and the time in rest during physical activity. Furthermore, strategies that maximize long-term endurance (adopted by "tortoises") and those that maximize short-term productivity (adopted by "hares") are appropriate to different work contexts (e.g., a subsistence or wage-labor economy) and suit individuals with different health status and ability. Thus, work intensity is an important aspect of the links between physical activity, health, productivity, and society, as noted in literature reviewing objectives for sustainable development and public health messages for disease risk management. These areas of scholarship are underresearched, partly because consensus has been slow in agreeing on which are the best measures of work pace and work intensity for use in field situations, and which

Social Determinants of Stroke as Related to Stress at Work among Working Women: A Literature Review

Directory of Open Access Journals (Sweden)

Susanna Toivanen

2012-01-01

Full Text Available In adult life, many of the social determinants of health are connected to working life. Yet, our knowledge of the role of work-related factors for the risk of stroke is fairly limited. In contemporary occupational health research, the Demand-Control Model (DCM is frequently used to measure work stress. Previous literature reviews of the association of work stress and cardiovascular disease (CVD do not include stroke as a specific outcome. Results regarding work stress and the risk of CVD are less evident in working women. With the focus on working women, the purpose of the present paper was to review the current research into the DCM in relation to stroke and to scrutinize potential gender differences. A literature search was performed and eight studies from three countries were identified. Based on the reviewed studies, there is some evidence that high psychological demands, low job control, and job strain are associated with increased stroke risk in women as well as in men. Any major reduction in deaths and disability from stroke is likely to come from decreasing social inequalities in health, and reducing work stress has a potential to contribute to a reduced risk of stroke in working populations.

Muscle fascicles lengthen in response to chronic passive stretch through in-series sarcomere addition in order to maintain an optimum sarcomere length. In turn, the muscles' force generating capacity, maximum excursion, and contraction velocity is enhanced. Thus, longer fascicles suggest a greater capacity to develop joint power and work. However, static fascicle length measurements may not be taking sarcomere length differences into account. Thus, we considered relative fascicle excursions through passive ankle dorsiflexion may better correlate with the capacity to generate joint power and work than fascicle length. Therefore, the aim of the present study was to determine if medial gastrocnemius relative fascicle excursions correlate with ankle joint power and work generation during gait in typically developing children. A sample of typically developing children (n = 10) were recruited for this study and data analysis was carried out on 20 legs. Medial gastrocnemius relative fascicle excursion from resting joint angle to maximum dorsiflexion was estimated from trigonometric relations of medial gastrocnemius pennation angle and thickness obtained from B-mode real-time ultrasonography. Furthermore, a three-dimensional motion capture system was used to obtain ankle joint work and power during the stance phase of gait. Significant correlations were found between relative fascicle excursion and peak power absorption (-) r(14) = -0.61, P = .012 accounting for 31% variability, positive work r(18) = 0.56, P = .021 accounting for 31% variability, and late stance positive work r(15) = 0.51, P = .037 accounting for 26% variability. The large unexplained variance may be attributed to mechanics of neighboring structures (e.g., soleus or Achilles tendon mechanics) and proximal joint kinetics which may also contribute to ankle joint power and work performance, and were not taken into account. Further studies are encouraged to provide greater insight

An intervention study was carried out to examine the effects of chewing gum on occupational stress and related outcomes. 101 volunteers from Cardiff University completed the study. The results showed that chewing gum reduced stress (both at work and outside work), reduced fatigue, reduced anxiety and depression and led to a more positive mood. Chewing gum was also associated with perceptions of better performance (both at work and outside). Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available A relationship between working memory impairment, disordered neuronal oscillations, and abnormal prefrontal GABA function has been hypothesized in schizophrenia; however, in vivo GABA measurements and gamma band neural synchrony have not yet been compared in schizophrenia. This case–control pilot study (N = 24 compared baseline and working memory task-induced neuronal oscillations acquired with high-density electroencephalograms (EEGs to GABA levels measured in vivo with magnetic resonance spectroscopy. Working memory performance, baseline GABA level in the left dorsolateral prefrontal cortex (DLPFC, and measures of gamma oscillations from EEGs at baseline and during a working memory task were obtained. A major limitation of this study is a relatively small sample size for several analyses due to the integration of diverse methodologies and participant compliance. Working memory performance was significantly lower for patients than for controls. During the working memory task, patients (n = 7 had significantly lower amplitudes in gamma oscillations than controls (n = 9. However, both at rest and across working memory stages, there were significant correlations between gamma oscillation amplitude and left DLPFC GABA level. Peak gamma frequency during the encoding stage of the working memory task (n = 16 significantly correlated with GABA level and working memory performance. Despite gamma band amplitude deficits in patients across working memory stages, both baseline and working memory-induced gamma oscillations showed strong dependence on baseline GABA levels in patients and controls. These findings suggest a critical role for GABA function in gamma band oscillations, even under conditions of system and cognitive impairments as seen in schizophrenia.

Abstract In children, the importance of detecting deficits after mild traumatic brain injury (mTBI) or concussion has grown with the increasing popularity of leisure physical activities and contact sports. Whereas most postconcussive symptoms (PCS) are similar for children and adults, the breadth of consequences to children remains largely unknown. To investigate the effect of mTBI on brain function, we compared working memory performance and related brain activity using blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (fMRI) in 15 concussed youths and 15 healthy age-matched control subjects. Neuropsychological tests, self-perceived PCS, and levels of anxiety and depression were also assessed. Our results showed that, behaviorally, concussed youths had significantly worse performances on the working memory tasks, as well as on the Rey figure delayed recall and verbal fluency. fMRI results revealed that, compared to healthy children, concussed youths had significantly reduced task-related activity in bilateral dorsolateral prefrontal cortex, left premotor cortex, supplementary motor area, and left superior parietal lobule during performance of verbal and nonverbal working memory tasks. Additionally, concussed youths also showed less activation than healthy controls in the dorsal anterior cingulate cortex, left thalamus, and left caudate nucleus during the nonverbal task. Regression analysis indicated that BOLD signal changes in bilateral dorsolateral prefrontal cortex were significantly correlated with performance such that greater activities in these regions, relative to the control condition, were associated with greater accuracy. Our findings confirmed functional alterations in brain activity after concussion in youths, a result similar to that observed in adults. However, significant differences were noted. In particular, the observation of reduced working memory accuracy suggests that youths may be unable to engage compensatory

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

Computer work has been identified as a risk factor for upper extremity musculoskeletal problems (UEMSP). But few studies have investigated how psychosocial and organizational work factors affect this relation. Nor have gender differences in the relation between UEMSP and these work factors  been studied. We sought to estimate: (1) the association between UEMSP and a range of physical, psychosocial and organizational work exposures, including the duration of computer work, and (2) the moderating effect of psychosocial work exposures on the relation between computer work and UEMSP. Using 2007-2008 Québec survey data on 2478 workers, we carried out gender-stratified multivariable logistic regression modeling and two-way interaction analyses. In both genders, odds of UEMSP were higher with exposure to high physical work demands and emotionally demanding work. Additionally among women, UEMSP were associated with duration of occupational computer exposure, sexual harassment, tense situations when dealing with clients, high quantitative demands and lack of prospects for promotion, and among men, with low coworker support, episodes of unemployment, low job security and contradictory work demands. Among women, the effect of computer work on UEMSP was considerably increased in the presence of emotionally demanding work, and may also be moderated by low recognition at work, contradictory work demands, and low supervisor support. These results suggest that the relations between UEMSP and computer work are moderated by psychosocial work exposures and that the relations between working conditions and UEMSP are somewhat different for each gender, highlighting the complexity of these relations and the importance of considering gender.

Full Text Available Background. Physical performances and cognition are positively related in cognitively healthy people. The aim of this study was to examine whether physical performances are related to specific cognitive functioning in older people with mild to severe cognitive impairment. Methods. This cross-sectional study included 134 people with a mild to severe cognitive impairment (mean age 82 years. Multiple linear regression was performed, after controlling for covariates and the level of global cognition, with the performances on mobility, strength, aerobic fitness, and balance as predictors and working memory and episodic memory as dependent variables. Results. The full models explain 49–57% of the variance in working memory and 40–43% of episodic memory. Strength, aerobic fitness, and balance are significantly associated with working memory, explaining 3–7% of its variance, irrespective of the severity of the cognitive impairment. Physical performance is not related to episodic memory in older people with mild to severe cognitive impairment. Conclusions. Physical performance is associated with working memory in older people with cognitive impairment. Future studies should investigate whether physical exercise for increased physical performance can improve cognitive functioning. This trial is registered with ClinicalTrials.gov NTR1482.

The present study was designed to determine the relationship between meaningful work and job performance, and the impact of meaningful work on nursing care quality. Meaningful work has been suggested as a significant factor affecting job performance, but the relationship has never been studied in nurses in China. A descriptive correlational study was designed to assess the level of meaningful work, tasks, and contextual performance as well as their relationships. We used a stratified random-sampling approach to enrol nurses from hospitals. Multivariate regression analysis was applied to determine the relationship between meaningful work and their demographic data. There were significant, positive relationships between meaningful work and task performance and contextual performance. Education level, work unit, and employment type influenced meaningful work. The work motivation score of the nurses was lower than that of the other 2 dimensions, and a negative work motivation score negatively influenced job performance. Improving meaningful work and providing more support and assistance could improve nurse performance, thereby improving the quality of nursing care. © 2018 John Wiley & Sons Australia, Ltd.

Work Ability Index (WAI) is a well-known and valid self-report tool that has been widely used in various studies to identify and avoid early retirement and work-related disability. Nevertheless, very few studies have been carried out to evaluate work ability in Iran. We aimed to investigate the WAI and the effect of work-related stress on it among Iranian workers. A cross-sectional, descriptive and analytic study was carried out among 449 workers from five working sectors in three big cities of Iran. Work ability and work-related stress were measured using the Persian version of WAI and the Persian version of Health and Safety Executive Stress Indicator Tool. More than a third of the workers surveyed (34.70%) did not have an appropriate level of work ability (WAI work-related stress and the mean score of WAI. Furthermore, the variables of body mass index, sleep quality, exercise activity, job tenure, and three subscales of work-related stress including demands, supervisor support, and role were significant predictors of WAI. According to the results of this study, the interventional programs must be focused on improving supervisors support, eliminating ambiguity and conflicts in the role of workers in their job and organization, reducing job demands, improving sleep quality, and increasing exercise activity.

To identify work-related musculoskeletal symptoms and any associated work-related risk factors, focusing on structural labor factors among hotel workers. A total of 1,016 hotel workers (620 men and 396 women) were analyzed. The questionnaire surveyed participants' socio-demographics, health-related behaviors, job-related factors, and work-related musculoskeletal symptoms. Work-related musculoskeletal symptoms were assessed using the Nordic musculoskeletal questionnaire. All analyses were stratified by gender, and multiple logistic regression modeling was used to determine associations between work-related musculoskeletal symptoms and work-related risk factors. The risk of developing work-related musculoskeletal symptoms was 1.9 times higher among male workers in the kitchen department than males in the room department (OR = 1.92, 95% CI = 1.03-3.79), and 2.5 times higher among male workers with lower sleep satisfaction than those with higher sleep satisfaction (OR = 2.52, 95% CI = 1.57-4.04). All of the aforementioned cases demonstrated a statistically significant association with work-related musculoskeletal symptoms. Moreover, the risk of developing work-related musculoskeletal symptoms was 3.3 times higher among female workers aged between 30 and 34 than those aged 24 or younger (OR = 3.32, 95% CI = 1.56-7.04); 0.3 times higher among females in the back office department than those in the room department (OR = 0.34, 95% CI = 0.12-0.91); 1.6 times higher among females on shift schedules than those who were not (OR = 1.60, 95% CI = 1.02-2.59); 1.8 times higher among females who performed more intensive work than those who performed less intensive work (OR = 1.88, 95% CI = 1.17-3.02), and; 2.1 times higher among females with lower sleep satisfaction than those with higher sleep satisfaction (OR = 2.17, 95% CI = 1.34-3.50). All of the aforementioned cases also displayed a statistically significant association with work-related musculoskeletal symptoms. This study

Full Text Available Orientation: Work-based identity, used as a reference to the self, is the answer to the question ’Who am I at work?’ Work-related identities, derived from different social foci through identity formation processes, have as behavioural guides a significant influence on employee behaviour, which, in turn has an impact on work outcomes. Engagement, presented in different conceptualisations, is viewed by practitioners and academic researchers as an important antecedent of employee behaviour.Research purpose: The main purpose of the study was to investigate whether work-based identity and work engagement differed (in combination with personal alienation, helping behaviour and burnout as potential antecedents (amongst numerous others of task performance and turnover intention.Research design: A census-based sampling approach amongst 23 134 employees in the employment of an ICT company yielded a sample of 2429 usable questionnaires. Scales used in the study were the Maslach Burnout Inventory (MBI-HSS-20, Utrecht Work Engagement Scale (UWES, Work-based Identity, Personal Alienation, Helping Behaviour, Turnover Intention and Task Performance Scales.Main findings: The findings indicate that work-based identity and work engagement give similar appearing results as potential predictors of turnover intention and task performance. Practical/managerial implications: Reducing withdrawal behaviours and enhancing work performance are everyday challenges for organisations. Interventions focused on enhancing work-based identity and work engagement in the work environment should have a meaningful impact when these behaviours need to be addressed.Contribution/value-add: Work-based identity as a multidimensional construct has the potential, with further refinement, to become a valuable construct that can play a leading role in future work engagement research.

To determine the incidence and epidemiological characteristics of work-related asthma in Korea. During 2004-2009, the Korea Work-Related Asthma Surveillance (KOWAS) program collected data on new cases of work-related asthma from occupational physicians, allergy and chest physicians, regional surveillance systems, and workers' compensation schemes. The incidence was calculated on the basis of industry, occupation, sex, age, and region. In addition, the distribution of causal agents was determined. During the study period, 236 cases of work-related asthma were reported, with 77 cases from more than 1 source. A total of 22.0% (n=52) were reported by occupational physicians, 52.5% (n=124) by allergy and chest physicians, 24.2% (n=57) by regional surveillance systems, and 43.2% (n=102) by workers' compensation schemes. The overall average annual incidence was 3.31 cases/million workers, with a rate of 3.78/million among men and 2.58/million among women. The highest incidence was observed in the 50-59-year age group (7.74/million), in the Gyeonggi/Incheon suburb of Seoul (8.50/million), in the furniture and other instrument manufacturing industries (67.62/million), and among craft and related trades workers (17.75/million). The most common causal agents were isocyanates (46.6%), flour/grain (8.5%), metal (5.9%), reactive dyes (5.1%), and solvents (4.2%). The incidence of work-related asthma in Korea was relatively low, and varied according to industry, occupation, gender, age, and region. Data provided by workers' compensation schemes and physician reports have been useful for determining the incidence and causes of work-related asthma.

Full Text Available The aim of this study was to assess the plasma adrenaline and noradrenaline concentrations as well as whole blood β2-adrenoceptor gene (ADRB2 expression in young ice hockey players before and immediately after exercise in relation to performed work. Nineteen Youth National Team ice hockey players were subjected to the maximal incremental cycloergometer exercise. The test was done in the pre-competitive phase of training. Among many parameters the plasma adrenaline and noradrenaline concentrations and ADRB2 gene expression in peripheral blood mononuclear cells (PBMC were determined before and after exercise. The average performed work was 3261.3 ± 558.3 J · kg-1 and maximal oxygen consumption (VO2max for all players was 53.85 ± 3.91 mL · kg-1 min-1. The geometric mean of the ADRB2 gene expression was statistically significantly different before and after exercise (P ≤ 0.05, while adrenaline and noradrenaline levels in plasma significantly increased after exercise. In the analysed group of athletes we found that initial level of plasma noradrenaline correlated with the performed work (r = - 0.55, P < 0.014 and normalized ADRB2 expression before the exercise correlated with the work done by them (r = 0.48, P<0.039. However, no statistically significant correlations were found between the plasma adrenaline or noradrenaline concentrations and ADRB2 gene expression in peripheral blood of the players. The performed work in the maximal incremental exercise test of regularly training young ice hockey players depends on the initial levels of noradrenaline in plasma and ADRB2 mRNA in PBMC.

Systematic review. Traumatic hand injuries are frequent cause of work related injuries and can result in prolonged durations of time loss from work. To systematically review available evidence to determine which prognostic factors predict return-to-work (RTW) following work-related traumatic hand injuries. We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO from 1980 to September 2013 and reference lists of articles. Studies investigating any prognostic factors of RTW after traumatic hand injury were included. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Identified factors were grouped into conceptual prognostic factor categories. We assessed 8 studies, which addressed 11 potential prognostic factors (i.e., sociodemographic factors, occupation, work compensation status, treatment related factors, impairment severity, location of injury, etc.). The quality of the studies was low to moderate. Across all included studies, RTW (original or modified work) occurred in over 60% of individuals by 6 months. There was consistent low-moderate quality evidence that individuals with more severe impairments and lower pre-injury income were less likely to RTW, and low-moderate quality evidence that age, gender and level of education had no impact on RTW. Evidence on other commonly cited prognostic factors were limited in the literature. Impairment severity and lower pre-injury income showed a consistent association with RTW following occupational hand injury, while other factors demonstrated no or variable effects across studies. Additional high-quality studies are warranted toward improving our understanding of the complex factors that mediate RTW following a traumatic work-related hand injury. 2a.

The role of the leader of a medical unit has evolved over time to expand from simply a medical role to a more managerial one. This study aimed to explore how the behavior of a hospital-based emergency department's (ED's) leader might be related to ED unit performance and ED employees' work satisfaction. One hundred and twelve hospital-based EDs in Taiwan were studied: 10 in medical centers, 32 in regional hospitals, and 70 in district hospitals. Three instruments were designed to assess leader behaviors, unit performance and employee satisfaction in these hospital-based EDs. A mail survey revealed that task-oriented leader behavior was positively related to ED unit performance. Both task- and employee-oriented leader behaviors were found to be positively related to ED nurses' work satisfaction. However, leader behaviors were not shown to be related to ED physicians' work satisfaction at a statistically significant level. Some ED organizational characteristics, however, namely departmentalization and hospital accreditation level, were found to be related to ED physicians' work satisfaction.

2016-11-01

To identify work-related factors associated with depressive symptoms and probable major depression in primary care teams. Cross-sectional study among primary care teams (community health workers, nursing assistants, nurses, and physicians) in the city of São Paulo, Brazil (2011-2012; n = 2940), to assess depressive symptoms and probable major depression and their associations with job strain and other work-related conditions. Community health workers presented higher prevalence of probable major depression (18%) than other primary care workers. Higher odds ratios for depressive symptoms or probable major depression were associated with longer duration of employment in primary care; having a passive, active, or high-strain job; lack of supervisor feedback regarding performance; and low social support from colleagues and supervisors. Observed levels of job-related depression can endanger the sustainability of primary care programs. Public Health implications. Strategies are needed to deliver care to primary care workers with depression, facilitating diagnosis and access to treatment, particularly in low- and middle-income countries. Preventive interventions can include training managers to provide feedback and creating strategies to increase job autonomy and social support at work.

2015-03-01

Full Text Available Among the Corporate Governance mechanisms, the Board of Directors is mentioned in academic research as fundamental in company performance and values in different countries. The important role in defense of the stockholders’ rights, preventing the managers from using the company in defense of their own interests, makes this a relevant mechanism in empirical research, even more when its relations with financial indicators is analyzed. In this study, the main objective was to analyze the relation between this mechanism and the value, performance and risk of Brazilian companies in 2012 and 2013, using panel data regression. Therefore, a Board of Directors index was created, based on binary questions, adapted from Silva, Santos and Almeida (2011, to be used as an independent variable in econometric models. A positive statistical relation was found between the proposed inedex and the variable Volatility, against expectations. The research also indicated relevant relations between the dependent and control variables. Among other results, it was concluded that: a positive relation exists between the company size and its performance; a positive relation exists between the growth of sales and the company value; a position relation between the risk variables beta and volatility; and belonging to the distinguished corporate governance levels on the stock exchange reduces the volatility of company stocks.

Anecdotally, veterinary surgeons report high levels of work-related stress. To investigate psychosocial working conditions, self-reported causes of work-related stress and satisfaction among a representative sample of vets practising in the UK. A cross-sectional study using a questionnaire mailed to a stratified random sample of 3200 vets. The Health & Safety Executive Management Standards Indicator Tool and a series of bespoke questions were embedded in a 120 item questionnaire, which also assessed anxiety and depressive symptoms, alcohol consumption, suicidal ideation, positive mental well-being and work-home interaction. A total of 1796 useable questionnaires were returned (response rate 56%). Number of hours worked and making professional mistakes were the main reported contributors to stress. Good clinical outcomes and relationships with colleagues were the greatest sources of satisfaction. Anxiety and depressive symptoms are associated with less favourable working conditions. Compared to the general population, the sample reported higher risk of work-related stress for demands and managerial support but lower risk for relationships and change. The results could be used to inform the development of targeted interventions.

This paper systematically reviews the scientific literature on the effects of individual and work-related factors on the Work Ability Index (WAI). Studies on work ability published from 1985 to 2006 were identified through a structured search in PubMed, and Web of Science. Studies were included if the WAI was used as measure of work ability and if quantitative information was presented on determinants of work ability. In total, 20 studies were included with 14 cross-sectional studies and six longitudinal studies. Factors associated with poor work ability, as defined by WAI, were lack of leisure-time vigorous physical activity, poor musculoskeletal capacity, older age, obesity, high mental work demands, lack of autonomy, poor physical work environment, and high physical work load. The WAI is associated with individual characteristics, lifestyle, demands at work, and physical condition. This multifactorial nature of work ability should be taken into account in health promotion programmes aimed at maintaining and promoting the participation of the labour force and improvement of the performance at work.

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

Work engagement has become a topic of great interest in recent years. However, clinicians' work engagement has rarely been studied and relatively little is known about its predictors and consequences. Therefore the objective of this cross-sectional questionnaire study was to test a model of possible institutional and personal predictors and significant relations to job and life satisfaction. 123 clinicians specializing in Surgery Medicine participated in the study. Self-administered questionnaires, including the Copenhagen Psychosocial Questionnaire, the Utrecht Work Engagement Scale, the Brief Resilient Coping Scale and the Questionnaire for Self-efficacy, Optimism and Pessimism, were administered. Bivariate analyses and a stepwise regression analysis were performed. The whole sample of surgeons rated work engagement with a high mean of M = 4.38; SD = .91. Job satisfaction and perceived quality of life have been rated with moderate scores. The results show that job resources have a greater impact on surgeons' work engagement than their job demands. Significant correlations between surgeons' work engagement, their job satisfaction and quality of life were found. Moreover, work engagement mediated the relation between institutional factors and surgeons' job satisfaction. Our research suggests that strengthening surgeons' work engagement will contribute to a more sustainable workplace, in terms of both individual and hospital performance. Therefore, increasing work engagement among surgeons should be of concern for supervisors and hospital managers. Future research should focus on further predictors that may have an influence on health professionals' work engagement. Another field for future research is to study potential effects of interventions on work engagement.

2016-01-01

Early numeracy is an important precursor for arithmetic performance, academic proficiency, and work success. Besides their apparent motor difficulties, children with cerebral palsy (CP) often show additional cognitive disturbances. In this study, we examine whether working memory, non-verbal intelligence, linguistic skills, counting and fine motor skills are positively related to the early numeracy performance of 6-year-old children with CP. A total of 56 children (M = 6.0, SD = 0.61, 37 boys) from Dutch special education schools participated in this cross-sectional study. Of the total group, 81% of the children have the spastic type of CP (33% unilateral and 66% bilateral), 9% have been diagnosed as having diskinetic CP, 8% have been diagnosed as having spastic and diskinetic CP and 2% have been diagnosed as having a combination of diskinetic and atactic CP. The children completed standardized tests assessing early numeracy performance, working memory, non-verbal intelligence, sentence understanding and fine motor skills. In addition, an experimental task was administered to examine their basic counting performance. Structural equation modeling showed that working memory and fine motor skills were significantly related to the early numeracy performance of the children (β = .79 and p working memory and early numeracy (β = .57, p working memory for early numeracy performance in children with CP and they warrant further research into the efficacy of intervention programs aimed at working memory training.

2013-04-01

Full Text Available Despite the interest in the neuroimaging of working memory, little is still known about the neurobiology of complex working memory in tasks that require simultaneous manipulation and storage of information. In addition to the central executive network, we assumed that the recently described salience network (involving the anterior insular cortex and the anterior cingulate cortex might be of particular importance to working memory tasks that require complex, effortful processing. Method: Healthy participants (n=26 and participants suffering from working memory problems related to the Kleine-Levin syndrome (a specific form of periodic idiopathic hypersomnia; n=18 participated in the study. Participants were further divided into a high and low capacity group, according to performance on a working memory task (listening span. In a functional Magnetic Resonance Imaging (fMRI study, participants were administered the reading span complex working memory task tapping cognitive effort. Principal findings: The fMRI-derived blood oxygen level dependent (BOLD signal was modulated by 1 effort in both the central executive and the salience network and 2 capacity in the salience network in that high performers evidenced a weaker BOLD signal than low performers. In the salience network there was a dichotomy between the left and the right hemisphere; the right hemisphere elicited a steeper increase of the BOLD signal as a function of increasing effort. There was also a stronger functional connectivity within the central executive network because of increased task difficulty. Conclusion: The ability to allocate cognitive effort in complex working memory is contingent upon focused resources in the executive and in particular the salience network. Individual capacity during the complex working memory task is related to activity in the salience (but not the executive network so that high-capacity participants evidence a lower signal and possibly hence a larger

Deficits in cognitive functioning associated with shift work are particularly relevant to occupational performance; however, few studies have examined how cognitive functioning is associated with specific components of shift work. This observational study examined how circadian phase, nocturnal sleepiness, and daytime insomnia in a sample of shift workers ( N = 30) were associated with cognitive flexibility during the night shift. Cognitive flexibility was measured using a computerized task-switching paradigm, which produces 2 indexes of flexibility: switch cost and set inhibition. Switch cost represents the additional cognitive effort required in switching to a different task and can impact performance when multitasking is involved. Set inhibition is the efficiency in returning to previously completed tasks and represents the degree of cognitive perseveration, which can lead to reduced accuracy. Circadian phase was measured via melatonin assays, nocturnal sleepiness was assessed using the Multiple Sleep Latency Test, and daytime insomnia was assessed using the Insomnia Severity Index. Results indicated that those with an earlier circadian phase, insomnia, and sleepiness exhibited reduced cognitive flexibility; however, specific components of cognitive flexibility were differentially associated with circadian phase, insomnia, and sleepiness. Individuals with an earlier circadian phase (thus more misaligned to the night shift) exhibited larger switch costs, which was also associated with reduced task efficiency. Shift workers with more daytime insomnia demonstrated difficulties with cognitive inhibition, whereas nocturnal sleepiness was associated with difficulties in reactivating previous tasks. Deficits in set inhibition were also related to reduced accuracy and increased perseverative errors. Together, this study indicates that task performance deficits in shift work are complex and are variably impacted by different mechanisms. Future research may examine

To investigate the predictive validity of the Word Memory Test (WMT), a verbal memory neuropsychological test developed as a performance validity measure to assess memory, effort, and performance consistency. Cohort study with 1-year follow-up. Workers' compensation rehabilitation facility. Participants included workers' compensation claimants with work-related head injury (N=188; mean age, 44y; 161 men [85.6%]). Not applicable. Outcome measures for determining predictive validity included days to suspension of wage replacement benefits during the 1-year follow-up and work status at discharge in claimants undergoing rehabilitation. Analysis included multivariable Cox and logistic regression. Better WMT performance was significantly but weakly correlated with younger age (r=-.30), documented brain abnormality (r=.28), and loss of consciousness at the time of injury (r=.25). Claimants with documented brain abnormalities on diagnostic imaging scans performed better (∼9%) on the WMT than those without brain abnormalities. The WMT predicted days receiving benefits (adjusted hazard ratio, 1.13; 95% confidence interval, 1.04-1.24) and work status outcome at program discharge (adjusted odds ratio, 1.62; 95% confidence interval, 1.13-2.34). Our results provide evidence for the predictive validity of the WMT in workers' compensation claimants. Younger claimants and those with more severe brain injuries performed better on the WMT. It may be that financial incentives or other factors related to the compensation claim affected the performance. Copyright © 2016 American Congress of Rehabilitation Medicine.

Considerable evidence suggests that how candidates react to selection procedures can affect their test performance and their attitudes toward the hiring organization (e.g., recommending the firm to others). However, very few studies of candidate reactions have examined one of the outcomes organizations care most about: job performance. We attempt to address this gap by developing and testing a conceptual framework that delineates whether and how candidate reactions might influence job performance. We accomplish this objective using data from 4 studies (total N = 6,480), 6 selection procedures (personality tests, job knowledge tests, cognitive ability tests, work samples, situational judgment tests, and a selection inventory), 5 key candidate reactions (anxiety, motivation, belief in tests, self-efficacy, and procedural justice), 2 contexts (industry and education), 3 continents (North America, South America, and Europe), 2 study designs (predictive and concurrent), and 4 occupational areas (medical, sales, customer service, and technological). Consistent with previous research, candidate reactions were related to test scores, and test scores were related to job performance. Further, there was some evidence that reactions affected performance indirectly through their influence on test scores. Finally, in no cases did candidate reactions affect the prediction of job performance by increasing or decreasing the criterion-related validity of test scores. Implications of these findings and avenues for future research are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved

Being right is its own reward: load and performance related ventral striatum activation to correct responses during a working memory task in youth.

The ventral striatum (VS) is a critical brain region for reinforcement learning and motivation. Intrinsically motivated subjects performing challenging cognitive tasks engage reinforcement circuitry including VS even in the absence of external feedback or incentives. However, little is known about how such VS responses develop with age, relate to task performance, and are influenced by task difficulty. Here we used fMRI to examine VS activation to correct and incorrect responses during a standard n-back working memory task in a large sample (n=304) of healthy children, adolescents and young adults aged 8-22. We found that bilateral VS activates more strongly to correct than incorrect responses, and that the VS response scales with the difficulty of the working memory task. Furthermore, VS response was correlated with discrimination performance during the task, and the magnitude of VS response peaked in mid-adolescence. These findings provide evidence for scalable intrinsic reinforcement signals during standard cognitive tasks, and suggest a novel link between motivation and cognition during adolescent development.

2010-05-01

Full Text Available Abstract This article introduces key concepts of work-related stress relevant to the clinical and research fields of psychosomatic medicine. Stress is a term used to describe the body's physiological and/or psychological reaction to circumstances that require behavioral adjustment. According to the Japanese National Survey of Health, the most frequent stressors are work-related problems, followed by health-related and then financial problems. Conceptually, work-related stress includes a variety of conditions, such as overwork, unemployment or job insecurity, and lack of work-family balance. Job stress has been linked to a range of adverse physical and mental health outcomes, such as cardiovascular disease, insomnia, depression, and anxiety. Stressful working conditions can also impact employee well-being indirectly by directly contributing to negative health behaviors or by limiting an individual's ability to make positive changes to lifestyle behaviors, such as smoking and sedentary behavior. Over the past two decades, two major job stress models have dominated the occupational health literature: the job demand-control-support model and the effort-reward imbalance model. In both models, standardized questionnaires have been developed and frequently used to assess job stress. Unemployment has also been reported to be associated with increased mortality and morbidity, such as by cardiovascular disease, stroke, and suicide. During the past two decades, a trend toward more flexible labor markets has emerged in the private and public sectors of developed countries, and temporary employment arrangements have increased. Temporary workers often complain that they are more productive but receive less compensation than permanent workers.

Joosen, Margot C W; Frings-Dresen, Monique H W; Sluiter, Judith K

2011-01-01

To gain insight into fatigued workers' perspectives regarding work experience before and after receiving vocational rehabilitation (VR) treatments. A qualitative survey was conducted using semi-structured interviews with 21 fatigued workers who attended an outpatient multi-component VR treatment. Six months after treatment, work-related limitations and employed VR strategies at work before treatment were explored. Next, VR treatment experiences regarding return-to-work (RTW) were explored. Two researchers performed partially independent, qualitative analyses that revealed topics, discussed by the project team, and organised into domains, categories and sub-categories. Work-related limitations were: symptoms of prolonged fatigue, personal limitations (e.g. lack of self-reflection on individual capacity and limitations), interpersonal factors, activities and conditions at work and life/work imbalance. Before the treatment, VR strategies such as work adaptations, well-intentioned advice and support, and/or referral to psychological or physical care were employed. VR treatment experiences on RTW were: personal challenges (e.g. gained awareness and coping skills), improved activities during work, work adaptations and unresolved problems (e.g. remaining fatigue symptoms and sickness absence). New information about work experiences before and after multi-component VR treatments in workers with prolonged fatigue may help employers, occupational physicians and other caregivers to develop VR strategies that better meet individuals' needs.

2012-01-01

The aim of the present study was to analyse the main and interaction effects of age and psychosocial work demands on mental wellbeing in a sample (N = 685; age M = 47 years) of engine room officers in the Swedish merchant fleet. As expected, work demands were highly related to general mental health as well as to perceived stress, while the main effect of age only related significantly to perceived stress. The interaction effects between high work demands and high age significantly explained the variance of general mental health as well as perceived stress. The results can be understood as a consequence of the rapid technological and organisational development in the shipping industry and suggest that it ought be of high priority to provide older employees with work-related resources to support their long-term work performance as well as their health and wellbeing.

Personality and adaptive performance at work: a meta-analytic investigation.

Science.gov (United States)

Huang, Jason L; Ryan, Ann Marie; Zabel, Keith L; Palmer, Ashley

2014-01-01

We examined emotional stability, ambition (an aspect of extraversion), and openness as predictors of adaptive performance at work, based on the evolutionary relevance of these traits to human adaptation to novel environments. A meta-analysis on 71 independent samples (N = 7,535) demonstrated that emotional stability and ambition are both related to overall adaptive performance. Openness, however, does not contribute to the prediction of adaptive performance. Analysis of predictor importance suggests that ambition is the most important predictor for proactive forms of adaptive performance, whereas emotional stability is the most important predictor for reactive forms of adaptive performance. Job level (managers vs. employees) moderates the effects of personality traits: Ambition and emotional stability exert stronger effects on adaptive performance for managers as compared to employees.

Coluccia, Anna; Lorini, Francesca; Ferretti, Fabio; Pozza, Andrea; Gaetani, Marco

2015-01-01

The issue of the assessment of work-related stress has stimulated in recent years, the production of several theoretical paradigms and assessment tools. In this paper we present a new scale for the assessment of organizational well-being and work-related stress specific for healthcare organizations (Work-related Stress Assessment Scale - WSAS). The goal of the authors is to examine the psychometric properties of the scale, so that it can be used in the healthcare setting as a work-related stress assessment tool. The answers of 230 healthcare professionals belonging to different roles have been analyzed. The study was realized in 16 Units of the University Hospital "S. Maria alle Scotte "of Siena. The exploratory factor analysis (EFA) revealed the presence of five factors with good internal consistency and reliability, "relationship to the structure of proximity" (α = 0.93) "change" (α = 0.92), "organization of work "(α = 0.81)," relationship with the company / Governance "(α = 0.87)" working environment "(α = 0.83). The analysis of SEM (Structural Equation Models) has confirmed the goodness of the factor solution (NNFI = 0.835, CFI = 0.921, RMSEA = 0.060). The good psychometric qualities, the shortness and simplicity of the scale WSAS makes it a useful aid in the assessment of work-related stress in health care organizations.

Understanding work related musculoskeletal pain: does repetitive work cause stress symptoms?

Bonde, J P; Mikkelsen, S; Andersen, J H; Fallentin, N; Baelum, J; Svendsen, S W; Thomsen, J F; Frost, P; Kaergaard, A

2005-01-01

Pain in the neck and upper extremity is reported with high frequency in repetitive work. Mechanical overload of soft tissues seems a plausible mechanism, but psychological factors have received considerable attention during the past decade. If psychological factors are important for development of regional pain in repetitive work, stress symptoms would likely be on the causal path. To examine whether objective measures of repetitive monotonous work are related to occurrence and development of stress symptoms. In 1994-95, 2033 unskilled workers with continuous repetitive work and 813 workers with varied work were enrolled. Measures of repetitiveness and force requirements were quantified using video observations to obtain individual exposure estimates. Stress symptoms were recorded at baseline and after approximately one, two, and three years by the Setterlind Stress Profile Inventory. Repetitive work, task cycle time, and quantified measures of repetitive upper extremity movements including force requirements were not related to occurrence of stress symptoms at baseline or development of stress symptoms during three years of follow up. The findings do not indicate that repetitive work is associated with stress symptoms, but small effects cannot be ruled out. Thus the results question the importance of mental stress mechanisms in the causation of regional pain related to repetitive work. However, the findings should be interpreted with caution because the stress inventory has not been validated against a gold standard.

Daily micro-breaks and job performance: General work engagement as a cross-level moderator.

2018-03-29

Despite the growing research on work recovery and its well-being outcomes, surprisingly little attention has been paid to at-work recovery and its job performance outcomes. The current study extends the work recovery literature by examining day-level relationships between prototypical microbreaks and job performance as mediated by state positive affect. Furthermore, general work engagement is tested as a cross-level moderator weakening the indirect effects of microbreaks on job performance via positive affect. Using multisource experience sampling method, the authors collected two daily surveys from 71 call center employees and obtained objective records of daily sales performance for two consecutive weeks (n = 632). Multilevel path analysis results showed that relaxation, socialization, and cognitive microbreaks were related to increased positive affect at work which, in turn, predicted greater sales performance. However, breaks for nutrition-intake (having snacks and drinks) did not show significant effects. Importantly, microbreaks had significant indirect effects on job performance via positive affect only for workers who had lower general work engagement, whereas the indirect effects did not exist for workers who had higher general work engagement. Furthermore, Bayesian multilevel analyses confirmed the results. Theoretical and practical implications, limitations, and future research directions are discussed.

In this paper, we systematically reviewed twenty-one factors that have been shown to either vary with or influence performance on working memory (WM) tasks. Specifically, we review previous work on the influence of intelligence, gender, age, personality, mental illnesses/medical conditions, dieting, craving, stress/anxiety, emotion/motivation, stereotype threat, temperature, mindfulness training, practice, bilingualism, musical training, altitude/hypoxia, sleep, exercise, diet, psychoactive substances, and brain stimulation on WM performance. In addition to a review of the literature, we suggest several frameworks for classifying these factors, identify shared mechanisms between several variables, and suggest areas requiring further investigation. This review critically examines the breadth of research investigating WM while synthesizing the results across related subfields in psychology. PMID:29899806

The workload, the quality of professional relationships and emotional involvement have a significant impact on distress and burnout in health care-workers; this impact has an hight variability among the different environments and different care facilities (hospital, erderly nursing homes, home care). The risk assessment of work-related stress performed in 2010 in a homecare agency highlighted organizational problems related to the content/context of work and risk factors for health and safety. High turn-over is evidenced as critical among the "sentinel events". The level of job-strain was moderate, even if some critical issues were evidenced especially in the group of physiotherapists; nurses were configured as a homogeneous group with a low level of job-strain. In informative meetings the workers identified the discomfort related to the time for transferring patients from their homes in a high-traffic metropolitan area was identified as the most critical aspect.

Positive affect is related to cognitive performance in multiple ways. It is associated with motivational aspects of performance, affective states capture attention, and information processing modes are a function of affect. In this study, we examined whether these links are relevant within individuals across time when they experience minor ups and downs of positive affect and work on cognitive tasks in the laboratory on a day-to-day basis. Using a microlongitudinal design, 101 younger adults (20-31 years of age) worked on 3 working memory tasks on about 100 occasions. Every day, they also reported on their momentary affect and their motivation to work on the tasks. In 2 of the 3 tasks, performance was enhanced on days when positive affect was above average. This performance enhancement was also associated with more motivation. Importantly, increases in task performance on days with above-average positive affect were mainly unrelated to variations in negative affect. This study's results are in line with between-person findings suggesting that high levels of well-being are associated with successful outcomes. They imply that success on cognitively demanding tasks is more likely on days when feeling happier. PsycINFO Database Record (c) 2014 APA, all rights reserved.

The present study investigated individual differences in information processing following errant behavior. Participants were initially classified as high or as low working memory capacity using the Operation Span Task. In a subsequent session, they then performed a high congruency version of the flanker task under both speed and accuracy stress. We recorded ERPs and behavioral measures of accuracy and response time in the flanker task with a primary focus on processing following an error. The error-related negativity was larger for the high working memory capacity group than for the low working memory capacity group. The positivity following an error (Pe) was modulated to a greater extent by speed-accuracy instruction for the high working memory capacity group than for the low working memory capacity group. These data help to explicate the neural bases of individual differences in working memory capacity and cognitive control. © 2017 Society for Psychophysiological Research.

Relations between OCBs, organizational justice, work motivation and self-efficacy

Full Text Available The importance of organizational citizenship behaviors (OCBs in organizations is well documented, and studies that originate from the interactionist perspective and combine personal and situational factors in predicting OCBs are needed. Toward this end, and based on a recent theoretical model, the current study attempted to predict OCB by organizational justice, work motivation, and self-efficacy. A research questionnaire measuring the three predictors was administered to 151 employees, and a measure of their OCB was provided by their supervisors. Whereas OCBs were found to be positively correlated with the three predictors, a hierarchical regression analysis revealed that only organizational justice and work motivation were significant predictors of OCBs. The study emphasizes the importance of using an interactionist perspective integrating endogenous and exogenous forces in studying the antecedents of OCBs. OCBs may be closely related to task performance and may be predicted by motivation related variables. Organizations may facilitate OCBs by improving organizational justice and raising work motivation among employees.

Office workers have a high prevalence of musculoskeletal conditions. This can be a significant economic burden due to health-related productivity loss. Individual and work-related factors related to office worker health-related productivity were investigated. A survey including the Health and Work Performance Questionnaire, which estimated productivity loss, also recorded individual and work-related factors with potential associations with health-related productivity. Muscle function and workstation ergonomics were examined through physical assessments. Linear models investigated the relationships between these factors and health-related productivity. Significant factors identified were occupational category (0.001 productivity loss was greater in office workers working as managers, with lower job satisfaction and psychological wellbeing, and those with musculoskeletal pain. Office worker health-related productivity loss is represented by a combination of both individual and work-related factors.

Dairy production in the United States is moving towards large-herd milking operations, resulting in an increase in task specialization and work demands. The objective of this project was to provide preliminary evidence of the association of a number of specific job conditions that commonly characterize large-herd parlor milking operations with work-related musculoskeletal symptoms (MSS). A modified version of the Standardized Nordic Questionnaire was administered to assess MSS prevalence among 450 US large-herd parlor workers. Worker demographics and MSS prevalences were generated. Prevalence ratios were also generated to determine associations of a number of specific job conditions that commonly characterize large-herd parlor milking operations with work-related MSS. Work-related MSS are prevalent among large-herd parlor workers, since nearly 80% report 12-month prevalences of one or more symptoms, which are primarily located in the upper extremities, specifically shoulders and wrist/hand. Specific large-herd milking parlor job conditions are associated with MSS in multiple body regions, including performing the same task repeatedly, insufficient rest breaks, working when injured, static postures, adverse environmental conditions, and reaching overhead. These findings support the need for administrative and engineering solutions aimed at reducing exposure to job risk factors for work-related MSS among large-herd parlor workers.

The link between work distress and negative mental health outcome is an emergent topic in the scientific literature. The studies that evaluated the risk of work-related psychopathologies in the different job sectors have obtained so far controversial and inconclusive results. The identification, by means of standardized evaluation tools, of the work activities at higher risk of poor mental health is a relevant target for the occupational psychiatry and medicine. To evaluate the relationship between the psychosocial work conditions and work related psychiatric disturbances and to verify the relationship between the higher pathogenic effect of work and specific job activities. A six-month diagnostic trial was conducted on 234 patients (35.4% women and 64.6% men). Psychiatric diagnoses were according to DSM-IV criteria; anxious and depressive dimensions were studied by means of Hamilton-Anxiety-Scale and Hamilton Scale for Depression; psychosocial work environments and bio-psycho-social features were measured by Naples-Questionnaire of Work Distress. Groups with higher and lower work-related pathogenesis were compared and their distribution among specific job activities was evaluated. Mood disorders were strongly linked to negative work environment. Patients with severe bullying obtained higher scores on Hamilton-Anxiety-Scale and Hamilton Scale for Depression than those with lower work-pathogenesis. The highest scores on Naples-Questionnaire of Work Distress were related to mood disorders, to poorer bio-psycho-social functioning and to higher work etiology. No significant relationship between work activities and work-related psychopathologies was found. Workplace bullying is predictive of work-related psychiatric disturbances with more severe clinical features and bio-psycho-social consequences. No significant differences were found about the relationship between work-related psychopathologies and work activities.

Full Text Available This paper aims to explore the relationship between the performance of small and medium enterprises (SMEs and working capital management. To make the research robust, accounting performance and measures of market related performance have been used to gauge the SMEs performance. This research utilizes secondary data obtained from the Alternative Investment Market concerning SMEs listed in the London Stock Exchange, to investigate the significance of working capital management towards the performance of SMEs. The working capital management components that were used in research are; account payable period APP, average collection period (ACP, return on assets (ROA and inventory holding period (IHP. The analysis of data involved the use of regression analysis and extensive use of correlation analysis in order to establish the relationship between working capital management and SME performance. The study established that the use of WCM components such as cash conversion cycle, return on assets, cash conversion cycle and inventory holding period have a significant impact on the performance of SMEs. Further, it was established that when SMEs invested heavily in inventories and receivables, they amassed low profits while investment in current assets in relation to total assets lead to elevated profitability. Hence, it was concluded that there is a compelling relationship between WCM and SME performance.

Perceived work ability refers to a worker's assessment of his or her ability to continue working in his or her job, given characteristics of the job along with his or her resources. Perceived work ability is a critical variable to study in the United States, given an aging workforce, trends to delay retirement, and U.S. policy considerations to delay the age at which full Social Security retirement benefits may be obtained. Based on the job demands-resources model, cognitive appraisal theory of stress, and push/pull factors related to retirement, we proposed and tested a conceptual model of antecedents and outcomes of perceived work ability using 3 independent samples of U.S. working adults. Data regarding workers' job characteristics were from self-report and Occupational Information Network measures. Results from relative importance analysis indicated that health and sense of control were consistently and most strongly related to work ability perceptions relative to other job demands and job and personal resources when perceived work ability was measured concurrently or 2 weeks later in samples with varying occupations. Job demands (along with health and sense of control) were most strongly related to work ability perceptions when perceived work ability was measured in a manufacturing worker sample 1.6 years later. Perceived work ability also predicted lagged labor force outcomes (absence, retirement, and disability leave) while controlling for other known predictors of each. Consistent indirect effects were observed from health status and sense of control to all 3 of these outcomes via perceived work ability. PsycINFO Database Record (c) 2015 APA, all rights reserved.

Geotechnical site works are comprehensive, and they constitute the first step of the construction process. This study performs data mining of geotechnical works and analyzes the database for the root causes of accidents. The Occupational Safety and Health Administration (OSHA) was chosen for the 1984-2013 time frame with 247 cases. Descriptive statistical analyses were performed to discuss variables such as the end use of the work, project type and cost, soil type and condition, type and degree of injury, cause and type of accident, unsafe acts, and occupation and union status of the victim. The results showed that these accidents have a high frequency of recurrence and have a high severity level (54.3% fatalities). In addition, a total of 838 violations were recorded with penalties reaching 5 million US dollars. This study emphasizes that project-specific countermeasures should be taken regarding the root causes of accidents, leading to vigorous strategies to develop safety measures.

The objectives of this study were to determine (a) whether school-age children with typical hearing demonstrate poorer auditory working memory performance in multitalker babble at degraded signal-to-noise ratios than in quiet; and (b) whether the amount of cognitive demand of the task contributed to differences in performance in noise. It was hypothesized that stressing the working memory system with the presence of noise would impede working memory processes in real time and result in poorer working memory performance in degraded conditions. Twenty children with typical hearing between 8 and 10 years old were tested using 4 auditory working memory tasks (Forward Digit Recall, Backward Digit Recall, Listening Recall Primary, and Listening Recall Secondary). Stimuli were from the standardized Working Memory Test Battery for Children. Each task was administered in quiet and in 4-talker babble noise at 0 dB and -5 dB signal-to-noise ratios. Children's auditory working memory performance was systematically decreased in the presence of multitalker babble noise compared with quiet. Differences between low-complexity and high-complexity tasks were observed, with children performing more poorly on tasks with greater storage and processing demands. There was no interaction between noise and complexity of task. All tasks were negatively impacted similarly by the addition of noise. Auditory working memory performance was negatively impacted by the presence of multitalker babble noise. Regardless of complexity of task, noise had a similar effect on performance. These findings suggest that the addition of noise inhibits auditory working memory processes in real time for school-age children.

to explore the sources and levels of stress at work and work ability among Croatian midwives. midwives are subjected to multiple stressors. Among health-care professionals, psychological distress for a prolonged period of time has negative effects on the worker's health, work ability and quality of patient care. 'Work ability' is a term describing a worker's resources related to physical, mental and social demands at work. As a measure of work ability in midwifery, the Work Ability Index (WAI) is considered to be a very predictive instrument; midwives with a poor WAI score usually leave their current job within five years. university hospitals in Zagreb, Croatia. cross-sectional design survey. 300 health-care workers (105 qualified midwives and 195 paediatric nurses) were invited to complete the questionnaire. The total response rate was 53% (158/300). The sample included 14.7% of all hospital-based midwives in Zagreb hospitals. the Occupational Stress Assessment Questionnaire (OSAQ) for health-care workers and the WAI questionnaire. over three-quarters of the midwives (46/60, 76.7%) believed that their job was stressful, and considered that insufficient work resources caused the most stress. More than half of the midwives associated an insufficient number of coworkers, unexpected situations, inadequate income, night work, incurable patients and poor organisation at work with a high level of stress. The perceived specific stressors differed between midwives and paediatric nurses in the same hospital. Insufficient work resources and poor organisation at work were more common stressors among midwives than paediatric nurses (pworkplace compared with paediatric nurses (pability. After adjusting for age, the difference in WAI score between the groups of workers was not significant.

This study investigated levels of burnout in the general population irrespective of occupation and relations between burnout and psychosocial work factors. A cross-sectional survey featuring sleep problems, psychological distress, burnout (Maslach Burnout Inventory-General Survey), and psychosocial factors at work, was mailed to a random sample of 3,000 participants, aged 20-60. Response rate was 61%. A high level (18%), a low level (19%), and an intermediate group (63%) for burnout were constructed. The high level group was associated with those who were > 50 years old, women, those experiencing psychological distress, and those with a poor psychosocial work climate. The analyses on variables significant in previous analyses showed that the high level group was strongly related to high demands, low control, lack of social support, and disagreeing about values at the workplace even when accounting for age, gender, and psychological distress. We conclude that psychosocial work factors are important in association to burnout regardless of occupation.

The objective of this paper is to determine the percent of adults with asthma attributable to work and describe characteristics of the work-related asthma population in New York State. Sociodemographic and control characteristics of those with and without work-related asthma are compared. Data from three population-based surveys and one case-based surveillance system were analyzed. Work-relatedness of asthma was determined by self-report for the population-based surveys and by physician report for the case-based system. Self-reported sociodemographic and control characteristics were analyzed for the population-based surveys by work-relatedness. The percent of work-relatedness among adults with current asthma in New York State ranged from 10.6% to 44.5%. Significantly more adults with work-related asthma had poorly controlled asthma than those without work-related asthma. More adults with work-related asthma also tended to be employed in the manufacturing, educational services, and public administration industries than the general population. The most frequently reported exposure was dust. Adults with work-related asthma have decreased control and adverse socioeconomic impacts compared to those with asthma that is not work-related. Increased recognition and physician reporting is necessary to further prevent the impact of work-related exposures.

Cho, Soohyun; Holyoak, Keith J; Cannon, Tyrone D

2007-09-01

We report a series of experiments using a pictorial analogy task designed to manipulate relational integration, interference resolution, and active maintenance simultaneously. The difficulty of the problems was varied in terms of the number of relations to be integrated, the need for interference resolution, and the duration of maintenance required to correctly solve the analogy. The participants showed decreases in performance when integrating multiple relations, as compared with a single relation, and when interference resolution was required in solving the analogy. When the participants were required to integrate multiple relations while simultaneously engaged in interference resolution, performance was worse, as compared with problems that incorporated either of these features alone. Maintenance of information across delays in the range of 1-4.5 sec led to greater decrements in visual memory, as compared with analogical reasoning. Misleading information caused interference when it had been necessarily attended to and maintained in working memory and, hence, had to be actively suppressed. However, sources of conflict within information that had not been attended to or encoded into working memory did not interfere with the ongoing controlled information processing required for relational integration. The findings provide evidence that relational integration and interference resolution depend on shared cognitive resources in working memory during analogical reasoning.

Performance analysis of organic Rankine cycles using different working fluids

Full Text Available Low-grade heat from renewable or waste energy sources can be effectively recovered to generate power by an organic Rankine cycle (ORC in which the working fluid has an important impact on its performance. The thermodynamic processes of ORCs using different types of organic fluids were analyzed in this paper. The relationships between the ORC’s performance parameters (including evaporation pressure, condensing pressure, outlet temperature of hot fluid, net power, thermal efficiency, exergy efficiency, total cycle irreversible loss, and total heat-recovery efficiency and the critical temperatures of organic fluids were established based on the property of the hot fluid through the evaporator in a specific working condition, and then were verified at varied evaporation temperatures and inlet temperatures of the hot fluid. Here we find that the performance parameters vary monotonically with the critical temperatures of organic fluids. The values of the performance parameters of the ORC using wet fluids are distributed more dispersedly with the critical temperatures, compared with those of using dry/isentropic fluids. The inlet temperature of the hot fluid affects the relative distribution of the exergy efficiency, whereas the evaporation temperature only has an impact on the performance parameters using wet fluid.

The Linkage Between Work Unit Performance Perceptions of U.S. Federal Employees and Their Job Satisfaction: An Expectancy Theory

2018-02-01

Full Text Available Public organizations are interested in how to improve their performance. Performance in a work unit can also influence employee job satisfaction due to positive expectations based on higher performance. Thus, our study attempts to investigate if organizational performance has an impact on employee motivation under the premise that employees who perform better in a work unit expect greater professional recognition and rewards. By using data from the 2013 Federal Employee Viewpoint Survey (FEVS, we find that employees who perceive higher levels of performance in a work unit have a higher level of job satisfaction. This paper further shows that performance perception based on rewards is also positively related to job satisfaction.However, underrepresented groups (female and non-white, older employees and mid-level (work experience from 6 to 14 years employees are less satisfied with higher work unit performance. Finally, employees in the distributive agency category are more satisfied with work unit performance while those in the regulatory agency category are less satisfied with work unit performance. In conclusion, organizations should recognize particular characteristics of employees to develop the policies related to performance management, and effectively utilize these policies in order to attract and retain proficient workers.

Effects of Cogmed working memory training on cognitive performance.

Etherton, Joseph L; Oberle, Crystal D; Rhoton, Jayson; Ney, Ashley

2018-04-16

Research on the cognitive benefits of working memory training programs has produced inconsistent results. Such research has frequently used laboratory-specific training tasks, or dual-task n-back training. The current study used the commercial Cogmed Working Memory (WM) Training program, involving several different training tasks involving visual and auditory input. Healthy college undergraduates were assigned to either the full Cogmed training program of 25, 40-min training sessions; an abbreviated Cogmed program of 25, 20-min training sessions; or a no-contact control group. Pretest and posttest measures included multiple measures of attention, working memory, fluid intelligence, and executive functions. Although improvement was observed for the full training group for a digit span task, no training-related improvement was observed for any of the other measures. Results of the study suggest that WM training does not improve performance on unrelated tasks or enhance other cognitive abilities.

Relation extraction from biomedical publications is an important task in the area of semantic mining of text. Kernel methods for supervised relation extraction are often preferred over manual feature engineering methods, when classifying highly ordered structures such as trees and graphs obtained from syntactic parsing of a sentence. Tree kernels such as the Subset Tree Kernel and Partial Tree Kernel have been shown to be effective for classifying constituency parse trees and basic dependency parse graphs of a sentence. Graph kernels such as the All Path Graph kernel (APG) and Approximate Subgraph Matching (ASM) kernel have been shown to be suitable for classifying general graphs with cycles, such as the enhanced dependency parse graph of a sentence. In this work, we present a high performance Chemical-Induced Disease (CID) relation extraction system. We present a comparative study of kernel methods for the CID task and also extend our study to the Protein-Protein Interaction (PPI) extraction task, an important biomedical relation extraction task. We discuss novel modifications to the ASM kernel to boost its performance and a method to apply graph kernels for extracting relations expressed in multiple sentences. Our system for CID relation extraction attains an F-score of 60%, without using external knowledge sources or task specific heuristic or rules. In comparison, the state of the art Chemical-Disease Relation Extraction system achieves an F-score of 56% using an ensemble of multiple machine learning methods, which is then boosted to 61% with a rule based system employing task specific post processing rules. For the CID task, graph kernels outperform tree kernels substantially, and the best performance is obtained with APG kernel that attains an F-score of 60%, followed by the ASM kernel at 57%. The performance difference between the ASM and APG kernels for CID sentence level relation extraction is not significant. In our evaluation of ASM for the PPI task, ASM

Effects of working memory contents and perceptual load on distractor processing: When a response-related distractor is held in working memory.

Science.gov (United States)

Koshino, Hideya

2017-01-01

Working memory and attention are closely related. Recent research has shown that working memory can be viewed as internally directed attention. Working memory can affect attention in at least two ways. One is the effect of working memory load on attention, and the other is the effect of working memory contents on attention. In the present study, an interaction between working memory contents and perceptual load in distractor processing was investigated. Participants performed a perceptual load task in a standard form in one condition (Single task). In the other condition, a response-related distractor was maintained in working memory, rather than presented in the same stimulus display as a target (Dual task). For the Dual task condition, a significant compatibility effect was found under high perceptual load; however, there was no compatibility effect under low perceptual load. These results suggest that the way the contents of working memory affect visual search depends on perceptual load. Copyright © 2016 Elsevier B.V. All rights reserved.

An aftercare programme following medical rehabilitation may be beneficial in order to reinforce and stabilize the positive effects of rehabilitation and to encourage individual health-related modifications of behaviour and lifestyle. Medical rehabilitation and the aftercare programme of the German Pension Insurance Fund primarily are intended to sustain earning capacity. As part of an evaluation of the Intensified Rehabilitation Aftercare Programme (IRENA) established by the German Pension Insurance Fund, work-related aspects in orthopaedic patients were analyzed based on various data sources. Firstly, the significance of institutional and individual conditions for utilization of IRENA alongside work was of interest. Secondly, the IRENA participants' judgements of the changes of work-related parameters due to the programme were examined, differentiating specifically by extent of earning capacity impairments as well as by particular work problems. The data set used for the analysis is composed of person-related routine data of the German Pension Insurance Fund relative to IRENA records of the year 2007 (n=30 663), interview data from orthopaedic rehabilitation centres providing IRENA (n=225), and questionnaires of IRENA participants (n=750) that were either collected during a broad evaluation of the IRENA programme or provided by the German Pension Insurance Fund. The results show that the compatibility of IRENA and work is facilitated by the institutional conditions. However, differences between inpatient and outpatient settings have to be recognized. The possibilities to participate in IRENA throughout the day frequently are more diverse in an outpatient setting. In contrast to inpatient centres, outpatient rehabilitation centres see clearly better chances for patients to return to work and to participate in IRENA alongside. With respect to the work-related parameters (work ability, periods of sick leave), clear improvements were reported by participants from

The 13th periodical inspection of the experimental fast reactor JOYO is being made from Jun. 2000 to Jan. 2003. While this inspection, from the end of Oct. 2000 to Nov. 2001, the MK-III modification work on heat transport system was made in lower region of the reactor containment vessel in the reactor facility (under floor area). In the MK-III modification work, the works important to radiation control were the replacement of intermediate heat exchangers (IHXs) and fixtures, and the picking out of the surveillance material from primary heat transport piping carried out in the maintenance building. Because the working areas of these works were executed in small space around the complicated primary heat transport piping, workability was bad and dose rate from the corrosion products (CP) in piping or fixtures was high. In such condition, radiation control was performed mainly concerned about external exposure. The planted total external exposure of the IHX replacement and related works was 7135 man-mSv (target of total dose control: less than 5708 man-mSv, 80% of the plan), derived from special radiation work plants for segmental works, concerned about work procedure, number of workers, period of work, dose rate of working area and surface dose rate of equipments. The special radiation control organization was established for such long and large-scale work. The spatial organization held detailed discussion about radiation control of this work with the execution section and contractors appropriately, performance careful external/internal exposure control and surface contamination control and made efforts to reduce te external exposure thoroughly. As a result of these action, the total external exposure was 2386 man·mSv (≅33% of the plan, ≅42% of the target) and the maximum individual exposure were 24.7 mSv for staffs and 21.7mSv for contractors. The dose rate, surface contamination and air contamination while the works were kept under the control level with the

The aim of this study was to determine reference physical performance values in older aging workers. Cross-sectional physical performance measures were collected for 736 manufacturing workers to assess effects of work and nonwork factors on age-related changes in musculoskeletal function and health. Participants underwent surveys and physical testing that included bioelectrical impedance analysis, range-of-motion measures, exercise testing, and dynamic assessment. Physical characteristics, such as blood pressure and body fat percentage, were comparable to published values. Dynamic and range-of-motion measurements differed from published normative results. Women had age-related decreases in cervical extension and lateral rotation. Older men had better spinal flexion than expected. Predicted age-related decline in lower-extremity strength and shoulder strength in women was not seen. Men declined in handgrip, lower-extremity strength, and knee extension strength, but not trunk strength, across age groups. There was no appreciable decline in muscle fatigue at the trunk, shoulder, and knee with aging for either gender, except for the youngest age group of women. Normative values may underestimate physical performance in "healthy" older workers, thereby underappreciating declines in less healthy older workers. Work may be preservative of function for a large group of selected individuals. A "healthy worker effect" may be greater for musculoskeletal disease and function than for heart disease and mortality. Clinicians and researchers studying musculoskeletal function in older workers can use a more specific set of reference values.

Assess team performance within a net-worked supervisory control setting while manipulating automated decision aids and monitoring team communication and working memory ability. Networked systems such as multi-unmanned air vehicle (UAV) supervision have complex properties that make prediction of human-system performance difficult. Automated decision aid can provide valuable information to operators, individual abilities can limit or facilitate team performance, and team communication patterns can alter how effectively individuals work together. We hypothesized that reliable automation, higher working memory capacity, and increased communication rates of task-relevant information would offset performance decrements attributed to high task load. Two-person teams performed a simulated air defense task with two levels of task load and three levels of automated aid reliability. Teams communicated and received decision aid messages via chat window text messages. Task Load x Automation effects were significant across all performance measures. Reliable automation limited the decline in team performance with increasing task load. Average team spatial working memory was a stronger predictor than other measures of team working memory. Frequency of team rapport and enemy location communications positively related to team performance, and word count was negatively related to team performance. Reliable decision aiding mitigated team performance decline during increased task load during multi-UAV supervisory control. Team spatial working memory, communication of spatial information, and team rapport predicted team success. An automated decision aid can improve team performance under high task load. Assessment of spatial working memory and the communication of task-relevant information can help in operator and team selection in supervisory control systems.

Comprehensibility, manageability and meaningfulness at work: Construct validity of a scale measuring work-related sense of coherence

Research purpose: The aim of the present study was to investigate the factorial invariance and the construct validity of a scale that measures Work-SoC. Motivation for the study: It might be useful to specifically apply the concept of sense of coherence to the work context. Research design, approach and method: Statistical analysis was performed on crosssectional (n = 3412 and longitudinal (n = 1286 questionnaire data collected in eight medium to large Swiss companies from diverse economic sectors (four industrialproduction companies, one food-processing company, one public-administration service and two hospitals. The dataset therefore covers a broad range of different occupational groups. Main findings: Multiple-group analyses indicated that the scale’s factor structure remains invariant across different employee groups and across time. High values in job resources were related to high values in Work-SoC whereas high values in job demands were related to low values in Work-SoC. Furthermore, Work-SoC acted as a partial mediator between job resources and work engagement. Practical/managerial implications: It can be concluded that Work-SoC might serve as a practical screening instrument for assessing an employee’s perception of the potential health-promoting qualities of his or her current work situation. Contribution/value-add: The study advances both the salutogenic theory and the field of positive occupational health psychology by redefining sense of coherence as an interactional and context-specific construct that is useful for intervention research.

2014-01-01

The primary objective of this exploratory study was to delineate the broad range of adjustments women breast cancer survivors draw upon to minimize cancer-related limitations at the workplace. The study also analyzed whether survivors used strategies to address work-related limitations in isolation or in combination with other strategies, and whether they used formal or informal strategies. Semi-structured, in-depth interviews were conducted with 14 women who were employed at the time of diagnosis of breast cancer and who continued to work during treatment or returned to work. Interviews were conducted 3 to 24 months after diagnosis. An iterative process was used to systematically analyze the data (the transcripts) using qualitative methods. Participants who worked during or after treatment adjusted their work schedule, performed fewer or other tasks, modified or changed their work environment, reduced non-work activities at the workplace, used cognitive prompts, and acted preemptively to make work tasks manageable after their return to work. Survivors used multiple adjustments and drew upon both formal and informal tactics to minimize or prevent cancer- or treatment-related effects from negatively affecting job performance. Knowledge about the broad range of both formal and informal strategies identified in this study may enable health care and social services providers, as well as cancer survivors and employers, to identify a wide range of specific strategies that may reduce the negative effects of work-related limitations in specific work settings. Insights gained from this analysis should inform future research on work and cancer survivorship. Copyright © 2014 Jacobs Institute of Women's Health. Published by Elsevier Inc. All rights reserved.

Effects of aging on cerebral oxygenation during working-memory performance: a functional near-infrared spectroscopy study.

Directory of Open Access Journals (Sweden)

Anouk Vermeij

Full Text Available Working memory is sensitive to aging-related decline. Evidence exists that aging is accompanied by a reorganization of the working-memory circuitry, but the underlying neurocognitive mechanisms are unclear. In this study, we examined aging-related changes in prefrontal activation during working-memory performance using functional Near-Infrared Spectroscopy (fNIRS, a noninvasive neuroimaging technique. Seventeen healthy young (21-32 years and 17 healthy older adults (64-81 years performed a verbal working-memory task (n-back. Oxygenated and deoxygenated hemoglobin concentration changes were registered by two fNIRS channels located over the left and right prefrontal cortex. Increased working-memory load resulted in worse performance compared to the control condition in older adults, but not in young participants. In both young and older adults, prefrontal activation increased with rising working-memory load. Young adults showed slight right-hemispheric dominance at low levels of working-memory load, while no hemispheric differences were apparent in older adults. Analysis of the time-activation curve during the high working-memory load condition revealed a continuous increase of the hemodynamic response in the young. In contrast to that, a quadratic pattern of activation was found in the older participants. Based on these results it could be hypothesized that young adults were better able to keep the prefrontal cortex recruited over a prolonged period of time. To conclude, already at low levels of working-memory load do older adults recruit both hemispheres, possibly in an attempt to compensate for the observed aging-related decline in performance. Also, our study shows that aging effects on the time course of the hemodynamic response must be taken into account in the interpretation of the results of neuroimaging studies that rely on blood oxygen levels, such as fMRI.

Employer support for innovative work and employees' job satisfaction and job-related stress.

Science.gov (United States)

Raykov, Milosh

2014-01-01

There are high levels of global and national underemployment, but limited information is available on the impact of this phenomenon on the quality of employees' working lives. This study examines the relations among perceived employer support for creative work, different forms of underemployment and employee quality of life, including job satisfaction, perceived job security and job satisfaction. The study was performed using cross-sectional data from the Canadian 2010 Work and Lifelong Learning Survey (WALL), which included 1,042 randomly selected currently employed participants between the ages of 18 and 64 years of age. The study found a significant inverse association between employer support for innovative work and different forms of underemployment. It also suggested a strong relationship between support for such work and participation in work-related informal learning. The results from this study confirmed the hypothesis that employer support for creative work is significantly associated with the quality of employees' working lives, as manifested through increased job security and job satisfaction. Employees experiencing greater support for workplace creativity report less job-related stress. The present study identified relatively low employer support for creative work and significant differences in the perception of support among managers and workers. The results of this study indicate that employer support for innovative work can mitigate significant underutilization of employee knowledge and skills. Such support can contribute to the reduction of job-related stress, increased job satisfaction and perceived job security. This kind of support can also improve the quality of life of employees and facilitate creativity and overall organizational and social development.

To examine the association between glycosylated hemoglobin (HbA1c) and four subscales of work-related psychosocial stress at study baseline and over time. We used survey data from a major HMO located in the Southeastern part of the US on health and healthy behaviors linked with patients' clinical, pharmacy and laboratory records for the period between 2005 and 2009. Study participants (n=537) consisted of working adults aged 25-59 years, diagnosed with diabetes mellitus (DM) but without advanced micro or macrovascular complications at the time of the survey. We estimated the baseline (2005) association between HbA1c and work-related psychosocial stress and their interactions using linear regression analysis. Using individual growth model approach, we estimated the association between HbA1c over time and work-related psychosocial stress. Each of the models controlled for socio-demographic variables, diet and physical activity factor, laboratory factor, physical examinations variables and medication use in a hierarchical fashion. After adjusting for all study covariates, we did not find a significant association between work-related psychosocial stress and glycemic control either at baseline or over time. Among fairly healthy middle aged working adults with DM, work-related psychosocial stress was not directly associated with glycemic control. Copyright © 2015 Diabetes India.

Conscientiousness, openness to experience and extraversion as predictors of nursing work performance: a facet-level analysis.

Science.gov (United States)

Ellershaw, Julia; Fullarton, Christie; Rodwell, John; Mcwilliams, John

2016-03-01

This study examined the relationships between the personality traits of conscientiousness, openness and extraversion at trait and facet-levels and three indicators of work role performance; proficiency, 'adaptivity' and proactivity measured at individual, team and organisational levels. This is one of the first studies to explore the relationship between personality, measured at trait and facet-level and performance using a comprehensive range of performance indicators. An online survey of 393 nurses from health-care organisations across Australia was conducted to test hypothesised relationships. Path analyses revealed numerous relationships between personality, measured at both trait and facet-levels, and work role performance. Conscientiousness was highlighted as the strongest driver of work role performance across all the indicators, with extraversion also strongly associated with work role performance. Openness to experience, previously considered a week predictor of performance, was, when examined at the facet-level, related to all of the work role performance indicators. Results suggests a bandwidth effect, where the personality traits drive global performance while the facets drive specific performance. Better understanding of the relationship between personality and work role performance will help nurse managers to foster the fit between individual and organisation, improving job satisfaction, engagement, retention and performance in role. © 2015 John Wiley & Sons Ltd.

Burnout among pilots: psychosocial factors related to happiness and performance at simulator training.

2018-06-18

In this study among airline pilots, we aim to uncover the work characteristics (job demands and resources) and the outcomes (job crafting, happiness and simulator training performance) that are related to burnout for this occupational group. Using a large sample of airline pilots, we showed that 40% of the participating pilots experience high burnout. In line with Job Demands-Resources theory, job demands were detrimental for simulator training performance because they made pilots more exhausted and less able to craft their job, whereas job resources had a favourable effect because they reduced feelings of disengagement and increased job crafting. Moreover, burnout was negatively related to pilots' happiness with life. These findings highlight the importance of psychosocial factors and health for valuable outcomes for both pilots and airlines. Practitioner Summary: Using an online survey among the members of a European pilots' professional association, we examined the relationship between psychosocial factors (work characteristics, burnout) and outcomes (simulator training performance, happiness). Forty per cent of the participating pilots experience high burnout. Job demands were detrimental, whereas job resources were favourable for simulator training performance/happiness. Twitter text: 40% of airline pilots experience burnout and psychosocial work factors and burnout relate to performance at pilots' simulator training.

2011-11-01

Ladder falls comprise 16% of all US workplace fall-related fatalities, and ladder use may be particularly hazardous among older workers. This follow-back study of injured workers from a nationally representative sample of US emergency departments (ED) focused on factors related to ladder falls in three domains of the work environment: work equipment, work practices, and worker-related factors. Risk factors for fractures, the most frequent and severe outcome, were also evaluated. Workers injured from a ladder fall, treated in one of the 65 participating ED in the occupational National Electronic Injury Surveillance System (NEISS) were asked to participate. The questionnaire included worker demographics, injury, ladder and work equipment and environment characteristics, work tasks, and activities. Multivariate logistic regression models estimated odds ratios and 95% confidence intervals of a work-related fracture. Three-hundred and six workers experiencing an injury from an--on average--7.5-foot-fall from a step, extension, or straight ladder were interviewed primarily from construction, installation, maintenance, and repair professions. Injuries were most frequently to the arm, elbow or shoulder; head, neck, or face with diagnoses were primarily fracture, strain, sprain, contusion or abrasion. Workers were most frequently standing or sitting on the ladder while installing, hanging an item, or performing a repair when they fell. Ladder movement was the mechanism in 40% of falls. Environmental conditions played a role in cases. There was a significant association between fracture risk and fall height while working on the ladder that was also influenced by older work age. This study advances knowledge of falls from ladders to support those who specify means and methods, select equipment, and plan, supervise, or manage the performance of employees working at heights.

2002-05-01

New and more effective treatments for cancer have resulted in individuals living longer with a better quality of life. Many more survivors are employed in the workplace. Cancer is no longer only an issue for survivors and their families; it has become an issue for the employer and the workplace. This article describes survey results of 4,364 long term cancer survivors in which they were asked to respond to items describing their ability to work, job discrimination, and quality of life. Thirty-five percent of survivors were working at the time they completed the survey, and 8.5% considered themselves unable to work. This research has shown that age, gender, ethnic group, and cancer type affected the working status of the survivors. Of survivors continuing to work, 7.3% indicated they had experienced job discrimination. The results indicate most cancer survivors do not perceive employment related problems, and are readily assimilated into the work force. Job discrimination and the ability to work is a quality of life issue.

This study aims to elucidate the interplay between borderline personality symptoms and working conditions as a pathway for impaired work performance among workers in the general population. Cross-sectional data from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2) were used, including 3672 workers. Borderline personality symptoms were measured with the International Personality Disorder Examination (IPDE) questionnaire. Working conditions (decision latitude, psychological job demands, job security and co-worker support) were assessed with the Job Content Questionnaire (JCQ). Impaired work performance was assessed as total work loss days per month, defined as the sum of days of three types of impaired work performance (inability to work, cut-down to work, and diminished quality at work). These were assessed with the WHO Disability Assessment Schedule (WHO-DAS). Common mental disorders (CMD) were assessed with the Composite International Diagnostic Interview (CIDI). Number of borderline personality symptoms was consistently associated with impaired work performance, even after controlling for type or number of adverse working conditions and co-occurrence of CMD. Borderline personality symptoms were associated with low decision latitude, job insecurity and low co-worker support. The relationship between borderline personality symptoms and work performance diminished slightly after controlling for type or number of working conditions. The current study shows that having borderline personality symptoms is a unique determinant of work performance. This association seems partially explained through the impact of borderline personality symptoms on working conditions. Future studies are warranted to study causality and should aim at diminishing borderline personality symptoms and coping with working conditions.

Ego Depletion Does Not Interfere With Working Memory Performance.

Science.gov (United States)

Singh, Ranjit K; Göritz, Anja S

2018-01-01

Ego depletion happens if exerting self-control reduces a person's capacity to subsequently control themselves. Previous research has suggested that ego depletion not only interferes with subsequent self-control but also with working memory. However, recent meta-analytical evidence casts doubt onto this. The present study tackles the question if ego depletion does interfere with working memory performance. We induced ego depletion in two ways: using an e-crossing task and using a Stroop task. We then measured working memory performance using the letter-number sequencing task. There was no evidence of ego depletion interfering with working memory performance. Several aspects of our study render this null finding highly robust. We had a large and heterogeneous sample of N = 1,385, which provided sufficient power. We deployed established depletion tasks from two task families (e-crossing task and Stroop), thus making it less likely that the null finding is due to a specific depletion paradigm. We derived several performance scores from the working memory task and ran different analyses to maximize the chances of finding an effect. Lastly, we controlled for two potential moderators, the implicit theories about willpower and dispositional self-control capacity, to ensure that a possible effect on working memory is not obscured by an interaction effect. In sum, this experiment strengthens the position that ego depletion works but does not affect working memory performance.

The worldwide burden of mental disorders is considerable, and on the rise, putting pressure on health care systems. Current reforms aim to improve the efficiency of mental health care systems by increasing service integration in communities and strengthening primary mental health care. In this context, mental health care professionals (MHPs) are increasingly required to work on interdisciplinary teams in a variety of settings. Little is known, however, about the profiles of MHPs in relation to their perceived work role performance. MHPs in Quebec (N = 315) from four local service networks completed a self-administered questionnaire eliciting information on individual and team characteristics, as well as team processes and states. Profiles of MHPs were created using a two-step cluster analysis. Five profiles were generated. MHPs belonging to profiles labelled senior medical outpatient specialized care MHPs and senior psychosocial outpatient specialized care MHPs perceived themselves as more performing than MHPs in other profiles. The profile labelled low-collaborators was significantly less performing than all other groups. Two other profiles were identified, positioned between the aforementioned groups in terms of the perceived performance of MHPs: the junior primary care MHPs and the diversified specialized care MHPs. Seniority within the team, delivering specialized type of care, and positive team processes were all features associated with profiles where perceived work performance was high. Overall, this study supports the case for initiatives aimed at improving stability and interdisciplinary collaboration in health teams, especially in primary care.

Common mental disorders (CMDs) are major causes of sickness absence and disability. Prevention requires knowledge of how individuals perceive causal mechanisms, and in this study we sought to examine work-related factors as causal attribution of CMDs. A trial sample of n = 1,193, recruited because they struggled with work participation due to CMDs, answered an open-ended questionnaire item about what they believed were the most important causes of their CMDs. The population included participants at risk of sickness absence, and participants with reduced work participation due to sickness absence, disability or unemployment. We used thematic content analysis and categorized responses from 487 participants who reported work-related factors as causal attributions of their CMDs. Gender differences in work-related causal attributions were also examined. The participants attributed their CMDs to the following work-related factors; work stress, leadership, reduced work participation, job dissatisfaction, work conflict, social work environment, job insecurity and change, workplace bullying, and physical strain. Women tended to attribute CMDs to social factors at work. Findings from this study suggest several work-related risk factors for CMDs. Both factors at the workplace, and reduced work participation, were perceived by study participants as contributing causes of CMDs. Thus, there is a need to promote work participation whilst at the same time targeting aversive workplace factors. Further, our findings indicate that work-related factors may affect women and men differently. This illustrates that the association between work participation and CMDs is complex, and needs to be explored further.

Post-relational databases provide high performance and are currently widely used in American hospitals. As few hospital information systems (HIS) in either China or Japan are based on post-relational databases, here we introduce a new-generation electronic medical records (EMR) system called Hygeia, which was developed with the post-relational database Caché and the latest platform Ensemble. Utilizing the benefits of a post-relational database, Hygeia is equipped with an "integration" feature that allows all the system users to access data-with a fast response time-anywhere and at anytime. Performance tests of databases in EMR systems were implemented in both China and Japan. First, a comparison test was conducted between a post-relational database, Caché, and a relational database, Oracle, embedded in the EMR systems of a medium-sized first-class hospital in China. Second, a user terminal test was done on the EMR system Izanami, which is based on the identical database Caché and operates efficiently at the Miyazaki University Hospital in Japan. The results proved that the post-relational database Caché works faster than the relational database Oracle and showed perfect performance in the real-time EMR system.

Work-related stress is common among medical caregivers and concerns all perioperative care providers. Although anesthesiologists are known to experience stress, there are limited Indian data addressing this issue. This survey was conducted among Indian anesthesiologists to determine their awareness about work stress and views regarding prevention programs. A survey questionnaire was distributed to delegates visiting the exhibits at the national anesthesiology conference in 2011. The questionnaire had ten questions on the work pattern, five on work-related stress, nine on opinion regarding the need and willingness to participate in stress-related programs. There were 1178 responders. Forty-three percent were faculty in medical institutions, 26% were residents and 25% were in free-lance practice. Ninety-one percent of participants rated their stress as moderate-extreme. There was a significant correlation between the amount of stress and working for more than 8 h ( P working on weekends ( P = 0.002), and carrying work back home ( P work stress. Eighty-four percent of participants felt the need for stress management programs and 69% expressed their willingness to participate in the same. The majority of participants rated their stress as moderate-extreme and was higher in anesthesiologists working long hours, over the weekend and those handling high-risk patients. A majority of participants felt the survey made them think about work-related stress and expressed their willingness to participate in stress management programs.

Cardador, M Teresa

2014-01-01

Research on task significance and relational job design suggests that information from beneficiaries of one's work fosters perceptions of impact, and thus improved work outcomes. This paper presents results from a longitudinal field experiment examining the effect of another strategy for fostering perceptions of impact - engaging employees in regular reflection about how their work benefits others. With a sample of professionals from multiple organizations, this longitudinal study examined the effect on job performance and work-life conflict of both positive and negative impact reflection. Results show that negative impact reflection had a pronounced negative effect on job performance, but no effect on work-life conflict. Positive impact reflection had a weak positive effect on work-life conflict, but no significant effect on job performance. The direction of effects seen in the no intervention condition mirrored that of the negative impact reflection condition, suggesting a possible buffering effect for positive impact reflection. This research provides empirical and theoretical contributions to the literatures on relational job design and task significance.

Work-related physical activity (PA) and work ability are of growing importance in modern working society. There is evidence for age- and job-related differences regarding PA and work ability. This study analyses work ability and work-related PA of employees in a medium-sized business regarding age and occupation. The total sample consists of 148 employees (116 men-78.38% of the sample-and 32 women, accounting for 21.62%; mean age: 40.85 ± 10.07 years). 100 subjects (67.57%) are white-collar workers (WC), and 48 (32.43%) are blue-collar workers (BC). Work ability is measured using the work ability index, and physical activity is obtained via the Global Physical Activity Questionnaire. Work ability shows significant differences regarding occupation (p = 0.001) but not regarding age. Further, significant differences are found for work-related PA concerning occupation (p Work ability is rated as good, yet, a special focus should lie on the promotion during early and late working life. Also, there is still a lack of evidence on the level of work-related PA. Considering work-related PA could add to meeting current activity recommendations.

This study investigates work performance among 79 mental health teams in Quebec (Canada). We hypothesized that work performance was positively associated with the use of standardized clinical tools and clinical approaches, integration strategies, "clan culture," and mental health funding per capita. Work performance was measured using an adapted version of the Work Role Questionnaire. Variables were organized into four key areas: (1) team attributes, (2) organizational culture, (3) inter-organizational interactions, and (4) external environment. Work performance was associated with two types of organizational culture (clan and hierarchy) and with two team attributes (use of standardized clinical tools and approaches). This study was innovative in identifying associations between work performance and best practices, justifying their implementation. Recommendations are provided to develop organizational cultures promoting a greater focus on the external environment and integration strategies that strengthen external focus, service effectiveness, and innovation.

This study aims to determine the prevalence of work-related musculoskeletal disorders in prosthetists/orthotists working in Australia. Secondary to this, the relationship between work-related hazards and work-related musculoskeletal disorders will be examined. In 2012 a self-report survey was conducted with the prosthetist/orthotist workforce in Australia (N=139, 56% response rate). Data on workplace physical and psychosocial hazards, job satisfaction, work life balance and musculoskeletal discomfort were collected. Predictors of work-related musculoskeletal disorders were assessed using logistic regression analysis. Prevalence of work-related musculoskeletal disorders was 80%. Gender (β= 1.31, p=0.03), total weekly hours (β=0.9, pwork-related musculoskeletal disorders. Females reported higher levels of work-related musculoskeletal disorder discomfort than males in all body areas. Work-related musculoskeletal disorders prevalence is high in prosthetists/orthotists. This suggests that focus on work place injury prevention is required. Targeted prevention requires systematic identification and then control of all relevant workplace hazards.

To investigate modifiable risk and preventive factors of work-related eye injuries. A case-crossover study conducted to explore the associations between transient risk factors and work-related eye injuries. Patients seen at seven medical centres in Taiwan with work-related eye injuries over a 4-year period were enrolled in the study. Clinical information was collected from medical charts and detailed information on exposure to eight potentially modifiable factors during the 60 minutes prior to the occurrence of each injury, as well as during the same time interval on the last work day prior to the injury, were obtained using questionnaire surveys. Matched-pair interval analysis was adopted to assess the odds ratios (ORs) for work-related eye injuries given exposure to the eight modifiable factors. A total of 283 subjects were interviewed. Most of these injured workers were young, male, and self-employed or small enterprise workers. The most common injury type was photokeratitis (33.2%), mainly caused by welding (30.4%). The OR for a work-related eye injury was increased with the performance of an unfamiliar task (57.0), operation of a faulty tool or piece of equipment (48.5), distractions (24.0), being rushed (13.0), or fatigued (10.0), and a poor work environment (4.3). Wearing eye protection devices was found to have a significant protective effect on workers who might otherwise have been exposed to eye injuries (OR = 0.4; 95% CI 0.2 to 0.7). Potential modifiable risk and preventive factors for work-related eye injuries were identified using a case-crossover study. This information should be helpful in the development of preventive strategies.

Several studies have shown that professional drivers are at risk of developing work-related stress. Stress may be responsible for a variety of adverse effects and may also be associated with an increased number of accidents. Perform an integrated, objective and subjective evaluation of work-related stress in bus drivers, that also considered the role of personality traits. Salivary α-amylase and cortisol were measured in 42 bus drivers. Subjective stress evaluation was performed with the Perceived Stress Scale (PSS-10) and Driver Stress Inventory (DSI). To evaluate personality traits, we administered the Eysenck Personality Questionnaire-Revised (EPQ-R) and the Impulsivity Inventory (IVE). Salivary biomarkers showed no associations with PSS-10 and personality traits. Cortisol levels were positively correlated with fatigue (r = 0.44) at the middle of the work-shift and with aggression (r = 0.51) at the end of a day off. At the end of the work-shift, cortisol levels were negatively correlated with hazard monitoring (r = -0.37) and salivary α-amylase was positively correlated with thrill-seeking (r = 0.36). Neuroticism (β= 0.44) and impulsiveness (β= 0.38) were predictors of perceived stress by multiple regression. An integrated method, considering both objective and subjective indicators, seems adequate to evaluate work-related stress in professional drivers. Personality traits are relevant in determining perception of stress.

In addition to demonstrating that human emotions improve work attention performance, numerous studies have also established that music alters human emotions. Given the pervasiveness of background music in the workplace, exactly how work attention, emotions and music listening are related is of priority concern in human resource management. This preliminary study investigates the relationship between work attention performance and emotions arising from listening to music. Thirty one males and 34 females, ranging from 20-24 years old, participated in this study following written informed consent. A randomized controlled trial (RCT) was performed in this study, which consisted of six steps and the use of the standard attention test and emotion questionnaire. Background music with lyrics adversely impacts attention performance more than that without lyrics. Analysis results also indicate that listeners self-reported feeling "loved" while music played that implied a higher score on their work-attention performance. Moreover, a greater ability of music to make listeners feel sad implied a lower score on their work-attention performance. Results of this preliminary study demonstrate that background music in the workplace should focus mainly on creating an environment in which listeners feel loved or taken care and avoiding music that causes individuals to feel stressed or sad. We recommend that future research increase the number of research participants to enhance the applicability and replicability of these findings.

Training Working Memory in Childhood Enhances Coupling between Frontoparietal Control Network and Task-Related Regions.

Science.gov (United States)

Barnes, Jessica J; Nobre, Anna Christina; Woolrich, Mark W; Baker, Kate; Astle, Duncan E

2016-08-24

Working memory is a capacity upon which many everyday tasks depend and which constrains a child's educational progress. We show that a child's working memory can be significantly enhanced by intensive computer-based training, relative to a placebo control intervention, in terms of both standardized assessments of working memory and performance on a working memory task performed in a magnetoencephalography scanner. Neurophysiologically, we identified significantly increased cross-frequency phase amplitude coupling in children who completed training. Following training, the coupling between the upper alpha rhythm (at 16 Hz), recorded in superior frontal and parietal cortex, became significantly coupled with high gamma activity (at ∼90 Hz) in inferior temporal cortex. This altered neural network activity associated with cognitive skill enhancement is consistent with a framework in which slower cortical rhythms enable the dynamic regulation of higher-frequency oscillatory activity related to task-related cognitive processes. Whether we can enhance cognitive abilities through intensive training is one of the most controversial topics of cognitive psychology in recent years. This is particularly controversial in childhood, where aspects of cognition, such as working memory, are closely related to school success and are implicated in numerous developmental disorders. We provide the first neurophysiological account of how working memory training may enhance ability in childhood, using a brain recording technique called magnetoencephalography. We borrowed an analysis approach previously used with intracranial recordings in adults, or more typically in other animal models, called "phase amplitude coupling." Copyright © 2016 Barnes et al.

Restless legs syndrome and impact on work performance

Diana Samara

2016-02-01

Full Text Available Restless legs syndrome (RLS is a neurological sensorimotor disorder characterized by unpleasant sensations in the legs and an uncontrollable urge to move them for relief. The RSL prevalence in the general population is 0.1% - 11.5%, and increases with age, with the highest effect of producing a primary sleep disorder (70%-80%. Women appear to be at increased risk, as do individuals with certain chronic conditions, including renal failure and anemia. The pathophysiology of RLS is incompletely understood, but it probably results from derangements in dopamine and iron metabolism, and has a genetic component. RSL could be idiopathic or secondary (usually related with iron deficiency, terminal renal failure, pregnancy, and spinal cord lesions. RLS patients usually have sleep disorders, so the disease can cause difficulties and problems in occupational and social life. Subjects with RLS symptoms appear to experience significantly more daytime problems, including being late for work, making errors at work, or missing work because of sleepiness. The diagnosis of RLS is made by following the criteria of the International Restless Legs Syndrome Study Group (IRLSSG. Pharmacologic RLS therapy, in which dopaminergic drugs constitute the first line, is effective and may have a dramatic effect on symptoms and quality of life. Identifying and treating RLS may improve sleep quality, daytime function and work performance.

Loi, Michela; Bellò, Benedetta; Mattana, Veronica

2015-01-01

The paper describes a case study of work related stress assessment in a public administration, based on an objective methodology (Romano, 2009). The Ispes1 forms (2010) have been used to perform the assessment. They have been filled during some focus group in which 45 workers have been involved, divided into 7 homogeneous groups relying on their department, back-office vs front-office typology of work and the office collocation. According to the Grounded Theory perspective, through the content analysis three further risk factors arose, comparing to the Ispesl forms, such as: (a) the quality of communication, (b) the relationship among and with leaders and colleagues, (c) the presence of discriminatory behaviours. Hence, on the basis of the results, mostly for a deeper analysis of work related stress assessment in a public administration, we suggest to consider these further risk factors.

2013-10-01

The Health and Safety Executive (HSE) has defined six management standards representing aspects of work that, if poorly managed, are associated with lower levels of employee health and productivity, and increased sickness absence. The HSE indicator tool aims to measure organizations' performance in managing the primary stressors identified by the HSE management standards. The aims of the study are to explore how the HSE indicator tool has been implemented within organizations and to identify contexts in which the tool has been used, its psychometric properties and relationships with alternative measures of well-being and stress. Studies that matched specific criteria were included in the review. Abstracts were considered by two researchers to ensure a reliable process. Full texts were obtained when abstracts met the inclusion criteria. Thirteen papers were included in the review. Using factor analysis and measures of reliability, the studies suggest that the HSE indicator tool is a psychometrically sound measure. The tool has been used to measure work-related stress across different occupational groups, with a clear relationship between the HSE tool and alternative measures of well-being. Limitations of the tool and recommendations for future research are discussed. The HSE indicator tool is a psychometrically sound measure of organizational performance against the HSE management standards. As such it can provide a broad overview of sources of work-related stress within organizations. More research is required to explore the use of the tool in the design of interventions to reduce stress, and its use in different contexts and with different cultural and gender groups.

The purpose of this study was to investigate the relationships among the factors that influence return to work for young individuals with mild stroke from different socioeconomic backgrounds. Prospective cohort study of working adults with mild stroke (N = 21). Participants completed an assessment battery of cognitive, work environment and work performance measures at approximately 3 weeks and 7 months post mild stroke. Individuals were placed in "skilled" and "unskilled" worker categories based on the Hollingshead Index. Unskilled workers had significantly poorer scores on the majority of the cognitive assessments. Unskilled workers also perceived less social support (p = 0.017) and autonomy (p = 0.049) in work responsibilities than individuals in the skilled worker group and also reported significantly poorer work productivity due to stroke than those in the skilled group (p = 0.015). Individuals from low socioeconomic backgrounds have more difficulty returning to work following mild stroke than individuals from higher socioeconomic backgrounds. Future work is needed to identify factors that can increase long-term work success and quality of work performance following a mild stroke that specifically targets the needs of individuals who have a lower socioeconomic status.

This study identified the relationship between work related stress, burnout, job satisfaction and general health of nurses. A total of 1200 nurses from four hospitals were invited to participate in this cross-sectional study (75% response rate. Participants completed five questionnaires and multiple linear regression analysis was used to determine significant relationships between variables. Staff issues are best associated with burnout as well as job satisfaction. Burnout explained the highest amount of variance in mental health of nurses. These are known to compromise productivity and performance, as well as affect the quality of patient care. Issues, such as security risks in the workplace, affect job satisfaction and health of nurses. Although this is more salient to developing contexts it is important in developing strategies and intervention programs towards improving nurse and patient related outcomes.

To provide a quantitative assessment of the occurrence of voice disorders among teachers and to identify associated work-related and individual factors in the teaching profession. A systematic review was conducted using three computerized databases on the occurrence of voice disorders among teachers and their associations with work-related and individual factors. Some of the keywords used were: "teacher", "voice disorder", "voice problem", and "dysphonia". Information regarding the occurrence of voice disorders and associations between work-related and individual factors and voice disorders were extracted from each paper. Occurrence and associations were expressed in prevalence and odds ratios, respectively. In total, 23 publications met the criteria for inclusion. All publications were cross-sectional studies. Prevalence estimates varied widely, reflecting disparity in definitions of "voice problem". Teachers had a significantly increased occurrence of voice disorders compared to other occupations. Several work-related and individual factors were consistently associated with voice disorders, most notably high levels of noise in classrooms, being a physical education instructor, and habitual use of a loud speaking voice. This review shows that teachers report voice disorders more often than non-teachers. Various work-related and individual factors are associated with reported voice disorders. Longitudinal studies are urgently required to get more insight into the development of voice disorders, their work-related determinants, and the consequences of these voice disorders for functioning and work performance among teachers. Describe the occurrence of voice disorders among teachers. Identify some work-related factors of voice disorders among teachers. Interpret the quality of the publications to describe or analyze the relationship between working conditions and voice disorders among teachers. Copyright © 2013 Elsevier Inc. All rights reserved.

Work engagement in nursing practice: a relational ethics perspective.

The concept of work engagement has existed in business and psychology literature for some time. There is a significant body of research that positively correlates work engagement with organizational outcomes. To date, the interest in the work engagement of nurses has primarily been related to these organizational outcomes. However, the value of work engagement in nursing practice is not only an issue of organizational interest, but of ethical interest. The dialogue on work engagement in nursing must expand to include the ethical importance of engagement. The relational nature of work engagement and the multiple levels of influence on nurses' work engagement make a relational ethics approach to work engagement in nursing appropriate and necessary. Within a relational ethics perspective, it is evident that work engagement enables nurses to have meaningful relationships in their work and subsequently deliver ethical care. In this article, I argue that work engagement is essential for ethical nursing practice. If engagement is essential for ethical nursing practice, the environmental and organizational factors that influence work engagement must be closely examined to pursue the creation of moral communities within healthcare environments. © The Author(s) 2014.

People who are in love have better attention for beloved-related information, but report having trouble focusing on other tasks, such as (home)work. So, romantic love can both improve and hurt cognition. Emotional information is preferentially processed, which improves task performance when the information is task-relevant, but hurts task performance when it is task-irrelevant. Because beloved-related information is highly emotional, the effects of romantic love on cognition may resemble these effects of emotion on cognition. We examined whether beloved-related information is preferentially processed even when it is task-irrelevant and whether this hurts task performance. In two event-related potential studies, participants who had recently fallen in love performed a visuospatial short-term memory task. Task-irrelevant beloved, friend, and stranger faces were presented during maintenance (Study 1), or encoding (Study 2). The Early Posterior Negativity (EPN) reflecting early automatic attentional capturing and the Late Positive Potential (LPP) reflecting sustained motivated attention were largest for beloved pictures. Thus, beloved pictures are preferentially processed even when they are task-irrelevant. Task performance and reaction times did not differ between beloved, friend, and stranger conditions. Nevertheless, self-reported obsessive thinking about the beloved tended to correlate negatively with task performance, and positively with reaction times, across conditions. So, although task-irrelevant beloved-related information does not impact task performance, more obsessive thinking about the beloved might relate to poorer and slower overall task performance. More research is needed to clarify why people experience trouble focusing on beloved-unrelated tasks and how this negative effect of love on cognition could be reduced. Copyright © 2017 Elsevier Ltd.

Synaptic Effects of Dopamine Breakdown and Their Relation to Schizophrenia-Linked Working Memory Deficits

Full Text Available Working memory is the ability to hold information “online” over a time delay in order to perform a task. This kind of memory is encoded in the brain by persistent neural activity that outlasts the presentation of a stimulus. Patients with schizophrenia perform poorly in working memory tasks that require the brief memory of a target location in space. This deficit indicates that persistent neural activity related to spatial locations may be impaired in the disease. At the circuit level, many studies have shown that NMDA receptors and the dopamine system are involved in both schizophrenia pathology and working memory-related persistent activity. In this Hypothesis and Theory article, we examine the possible connection between NMDA receptors, the dopamine system, and schizophrenia-linked working memory deficits. In particular, we focus on the dopamine breakdown product homocysteine (HCY, which is consistently elevated in schizophrenia patients. Our previous studies have shown that HCY strongly reduces the desensitization of NMDA currents. Here, we show that HCY likely affects NMDA receptors in brain regions that support working memory; this is because these areas favor dopamine breakdown over transport to clear dopamine from synapses. Finally, within the context of two NMDA-based computational models of working memory, we suggest a mechanism by which HCY could give rise to the working memory deficits observed in schizophrenia patients.
