We model nicotine from environmental tobacco smoke (ETS) in office air and salivary cotinine in nonsmoking U.S. workers. We estimate that: an average salivary cotinine level of 0.4 ng/ml corresponds to an increased lifetime mortality risk of 1/1000 for lung cancer, and 1/100 for heart disease; >95% of ETS-exposed office workers exceed OSHA's significant risk level for heart disease mortality, and 60% exceed significant risk for lung cancer mortality; 4000 heart disease deaths and 400 lung cancer deaths occur annually among office workers from passive smoking in the workplace, at the current 28% prevalence of unrestricted smoking in the office workplace.  相似文献

Shift work has been reported to predict health problems, and a possible explanation is that shift work may lead to poorer health habits, thereby increasing a person's vulnerability to illness. This study examined the association between shift work and health habits, as indicated by smoking, alcohol intake, physical activity and by being overweight. A questionnaire was sent to all 2795 female nurses working in the 10 hospitals of two Finnish health care districts. From the 2299 respondents, we selected those 506 shift workers who reported having always done shift work and those 183 day workers who had never done shift work. Shift workers were found to smoke more and to be overweight more often than day workers. These differences gradually increased in each successive age group, being 1.94 pack-years in smoking and 0.9 kg m-2 in body mass index among nurses over 45 years of age. Shift work was not associated with alcohol intake or sedentary lifestyle. This evidence is compatible with the possibility that shift work in nurses increases smoking and being overweight to a degree that contributes to health problems, including coronary heart disease.  相似文献

Abstract

The role of individual factors in youth as predictors of adult health resources, job factors and health risk behaviour was studied in men and women. The studied health risk behaviours were smoking, use of alcohol and sedentary behaviour. Sense of coherence (SOC) was the used measure of adult health resources. The pre-employment data had been collected from a sample of 1084 subjects representative of Finnish youth at the mean age of 12 years. For this follow-up study, 345 women and 361 men, working in Finland, responded to a questionnaire at the mean age of 36 years. In the analyses of structural relationships, individual factors in youth were related to adult variables for both sexes, although only two consistent relationships were found for women: outgoing, social activities in youth predicted adult smoking and use of alcohol. Of the job factors, low job demands were related to smoking and lack of support at work was related to sedentary behaviour in women. The strong relationships of SOC with perceptions of social support and influence at work for both sexes characterized its role in health-promoting experiences at work, and supported its importance as a general health resource.  相似文献

Abstract

Pride in task completion has been observed to be consistently important to workers, although these self-conscious emotions have received little attention as a construct worthy of investigation in the workplace. Organizational ethnographies provide a unique opportunity for an in-depth look at pride and Organizational Citizenship Behaviour (OCB), An analysis of the existing set of published book-length workplace ethnographies (n = 108) reveals that both job satisfaction and pride in task completion are significantly associated with OCB. Associations between pride and OCB appear to be stronger than associations between job satisfaction and OCB. Workers' characteristic mood states, such as the pleasurable emotions created by pride in work and unpleasant feelings of shame from perceptions of chronic failure, appear to be highly relevant to the promotion of desirable outcomes for organizations. The results of this study illustrate the value of ethnographic data in the study of workplace emotions, cognitions, and their potential behavioural sequelae  相似文献

ABSTRACT

This study compared the effects of accurate (i.e., contingent) and inaccurate (i.e., non-contingent) feedback on work performance under two different work conditions. Under one work condition, participants could clearly see the outcome of their performance (i.e., visible condition). Under the other condition, they could not clearly see the outcome of their performance (i.e., non-visible condition). One hundred and twenty participants were randomly assigned to four experimental conditions (i.e., accurate/visible, inaccurate/visible, accurate/non-visible, and inaccurate/non-visible) and asked to perform a simulated work task. The results indicated that inaccurate feedback was as effective as accurate feedback under the non-visible condition, but inaccurate feedback was less effective than accurate feedback under the visible condition.  相似文献

ABSTRACT

Research and theory on deviance in work groups suggest that non-prototypical members risk devaluation and mistreatment by their peers. Drawing on the self-categorisation theory, we propose and test a contextual model to explain workplace bullying from a target perspective, using non-prototypicality as a predictor and social identification and anti-bullying norms at the work group level as two- and three-way cross-level moderators. Multilevel modelling and a sample of employees from the university sector in the Low Lands (n?=?572) was employed. In line with our first hypothesis, we found that risk of exposure to workplace bullying is particularly high for non-prototypical work group members. We also hypothesised that work group social identification would facilitate bullying of non-prototypical members, while anti-bullying norms would buffer it. Results showed, however, that both conditions acted as buffering moderators on the main association. Lastly, the combination of the two also entailed a cross-level three-way interaction effect, showing that non-prototypicality is associated with bullying only in work groups characterised by low levels on both moderators. These novel and partly unexpected results demonstrate the relevance and significance of group level explanations for workplace bullying, holding significant implications for scholars and practitioners.  相似文献

Abstract

Appointment coordinators at a mid-western medical clinic were to provide exceptional telephone customer service. This included using a standard greeting, speaking in an appropriate tone of voice during the conversation, and using a standard closing to end the call. An analysis suggested performance deficiencies resulted from weak antecedents, poor knowledge and skills, and weak performance contingencies. An intervention package consisting of task clarification, goal setting, feedback, and performance contingent consequences was designed to improve customer service behaviors of four participating appointment coordinators. An ABAB reversal design was used, and overall performances of all four participants increased during intervention phases. This study indicates that a multi-component intervention may be an effective strategy to increase telephone customer service behavior in medical clinic settings.  相似文献

Positive associations between physical attractiveness and employee reward are well-documented within the organisational literature. Although the impact of facial cues to trustworthiness and dominance on a number of social outcomes has been established outside of the workplace, the extent to which they, in addition to attractiveness, affect pay at different managerial levels is yet to be investigated. This paper presents research into this issue using a face payment task for shop floor managers (Retail Managers) and senior managers (Heads of Retail Operations). Evaluations indicated that all three facial cues were positively associated with awarded pay at both managerial levels. Moreover, attractiveness had a significantly stronger link with shop-floor managers' than senior managers' pay, whereas perceived trustworthiness and perceived dominance had significantly stronger links with pay for senior managers than shop-floor managers. It further emerged that women were paid more in this experimental task where pay was awarded solely based on facial features and that the facial features were more predictive of women's than men's pay. Awareness of the role of physical cues in pay awards can be considered by organisations to reduce biases in remuneration.  相似文献

Abstract

This study examined the effects of an individual monetary incentive system with and without feedback to determine if feedback would supplement the effects of incentives. Participants were seven college students who performed a computerized task called SYNWORK. SYNWORK presented four sub-tasks concurrently: memory, arithmetic, visual monitoring and auditory monitoring. Participants earned points for correct responses. The dependent variable was the number of points earned. An ABAC design was used with A = individual monetary incentives without feedback, B = individual monetary incentives with feedback, and C = hourly pay with feedback. Sessions were 90 minutes, and there were 5 to 10 sessions per phase. The point scores of six of the seven participants increased when feedback was added to the incentive system but stabilized or continued to increase when feedback was removed. The feedback intervention was staggered in time across participants, and performance increased when feedback was added, hence the data suggest that feedback enhanced the effects of the incentives. One possible reason for the reversal failure is that feedback evoked higher levels of performance that were then maintained by the additional incentives. Because performance did not reverse, however, the results must be viewed cautiously.  相似文献

ABSTRACT

A commonly held belief among business professionals is that rapport-building activities in the workplace can enhance organizational outcomes and employee satisfaction. However, limited research has evaluated the effects of rapport-building behaviors on productivity and discretionary effort. Thus, the purpose of the current study was to examine the effects of engaging in rapport-building behaviors on productivity and discretionary effort in comparison to a control group in an analogue setting. Participants in the present study consisted of 48 undergraduate students who were assigned to either the rapport-building behaviors group or the control group. Participants completed a check-processing task to evaluate productivity and were asked to complete an optional survey to evaluate discretionary effort. The results indicated that rapport-building behaviors group had higher levels of productivity and engaged in more discretionary effort than the control group.  相似文献

Abstract

Several behaviors in a ski shop were identified as being deficient using Austin's Performance Diagnostic Checklist (2000) and Daniels and Daniels' PIC/NIC Analysis (2004). During a 4-week baseline, 7 cleaning behaviors were monitored and 5 were subsequently targeted in an intervention package using an ABC design. The intervention included: a task clarification session, a posted behavioral checklist, graphic feedback of the group's performance for the previous week, and daily task-specific feedback. Immediately after the checklist was posted, the frequency of employee cleaning behaviors increased 52%. Cleaning behaviors increased an additional 12% after the implementation of daily task-specific feedback. Results suggest the interventions generalized to the 2 cleaning behaviors not mentioned in the task-clarification session.  相似文献

Summary

The effect of two types of verbal consequences, rule-following feedback and task performance feedback, on rule-induced insensitivity to programmed schedules of reinforcement were examined. Rule-following feedback could be either accurate or non-contingently positive. The task involved moving a sign through a grid using telegraph keys operating on a multiple DRL 6/FR 18 schedule of reinforcement in the presence of an initially accurate rule. After acquisition, the multiple schedule was changed without notice to a FR 1/FI Yoked schedule. Accurate rule-following feedback plus feedback on task performance produced striking insensitivity to the DRL 6 to FR 1 schedule change, the opposite of what might be expected by a common sense analysis of task performance feedback, even after controlling for contact with the changed contingency. It is argued that findings such as these can only be understood by considering the mutual verbal relations evoked by the combinations of rules and feedback, rather than treating feedback as a simple consequential event or as a verbal consequence whose effects do not depend on the relations sustained with other events.  相似文献

ABSTRACT

Feedback involves providing information about past performance and indicating how to improve future performance. Although the literature contains numerous examples of feedback as an effective method for improving performance across a range of organizational settings, much remains unknown about the specifics of how feedback acts to change behavior. This study evaluated the combined effects of feedback accuracy (100%, 80%, 20%) and timing (feedback following each trial or after a block of 25 trials) on skill acquisition in undergraduate students when presented with a computerized match-to-sample task that required participants to learn the names of shapes. Results reveal that feedback accuracy had a significantly greater effect on performance than the timing of the feedback.  相似文献

Abstract

The current study used a multiple baseline design to investigate the effects of graphic feedback, goal setting, and manager praise on customer service behaviors in a large retail setting. Direct observation of customer greeting, eye contact, and smiling was used to collect data. After baseline data were collected feedback graphs were posted twice each week in the employee break room. A second intervention phase included goal setting and manager praise. Goals were developed based on employees' prior performance and were posted on the graphs. Managers then delivered immediate, verbal praise to employees. Graphic feedback produced slight increases in the customer interaction variables in the front of stores 1 and 2. Another small increase in performance was seen in the back of store 1 and the front and back of store 2 with the implementation of the interventions.  相似文献

Abstract

We aimed to investigate (1) the association between job insecurity and workplace bullying from the perspective of both targets and perpetrators and (2) perceived employability as a moderator of these relationships. We argue that job insecurity is associated with social or interpersonal strain as in the case of workplace bullying. Furthermore, workers who feel that they have alternative opportunities for employment may find it easier to cope with insecurity. Stated differently, we aimed to investigate whether the relationship between job insecurity and workplace bullying depended on the level of perceived employability. Hypotheses were tested among 693 workers who participated in a survey on the quality of working life. They were employed at establishments of two Belgian organizations from the textile industry (N=189) and financial services (N=505). We found that that job insecurity was associated with targets' and perpetrators' reports of workplace bullying. The interaction between job insecurity and perceived employability did not contribute to targets' reports of workplace bullying. However, it was related to perpetrators' reports of workplace bullying. Interestingly, the relationship between job insecurity and workplace bullying was stronger under the condition of high versus low employability. This hints at the idea that there could be a “dark side” to employability.  相似文献

Lack of data on daily inhalation rate and activity of children has been an issue in health risk assessment of air pollutants. This study aimed to obtain the daily inhalation rate and intensity and frequency of physical activity in relation to the environment in Japanese preschool children. Children aged four–six years (n= 138) in the suburbs of Tokyo participated in this study, which involved three days' continuous monitoring of physical activity using a tri‐axial accelerometer and parent's completion of a time/location diary during daily life. The estimated three‐day mean daily inhalation rate (body temperature, pressure, saturated with water vapor) was 9.9 ± 1.6 m3/day (0.52 ± 0.09 m3/kg/day). The current daily inhalation rate value of 0.580 m3/kg/day proposed for use in health risk assessment in Japan is confirmed to be valid to calculate central value of inhaled dose of air pollutants in five‐ to six‐year‐old children. However, the 95th percentile daily inhalation rate of 0.83 m3/kg/day based on measurement for five‐year‐old children is recommended to be used to provide an upper bound estimate of exposure that ensure the protection of all five‐ to six‐year‐old children from the health risk of air pollutants. Children spent the majority of their time in sedentary and light level of physical activity (LPA) when indoors, while 85% of their time when outdoors was spent in LPA and moderate‐to‐vigorous physical activity. The results suggest the need to consider variability of minute respiratory ventilation rate according to the environment for more refined short‐term health risk assessment.  相似文献

Abstract

Karasek'sJob Strain model was tested in a sample of 122 office workers. Two rounds ofdata were collected and used to examine the reliability of the results and the relationships between job characteristics and worker strain over time. Moderated regression analyses based on standard scores of the independent variables were conducted to examine the interaction of job control and workload, and of skill utilization and workload, on various indicators of worker strain. The results indicated that there was neither multiplicative nor adhtive effect ofjob control/skill utilization and workload on worker strain. Some of the relationships between job characteristics and worker strain were not stable over time. The cross-lagged correlation analysis showed that workload at Time 1 had some effect on one ofthe worker strain indxators at Time 2, but not the reverse.  相似文献

Abstract

The performance diagnostic checklist (PDC) was administered to examine the variables influencing the offering of promotional stamps by employees at two sites of a restaurant franchise. PDC results suggested that a lack of appropriate antecedents, equipment and processes, and consequences were responsible for the deficits. Based on these results, an intervention consisting of task clarification, self-monitoring, equipment modification, goal setting, and graphic feedback was implemented and evaluated with a multiple baseline design across settings. The results for restaurant 1 yielded baseline and intervention means of 25% and 72%, respectively. The results for restaurant 2 yielded baseline and intervention means of 11% and 80%, respectively. Overall, these results suggest that the PDC is a useful tool for guiding intervention selection for performance deficits which occur across more than one site.  相似文献

Abstract

In a national study of the work environment, physical, and mental well-being of more than 2600 Swedish nurses, 30% reported having experienced violence at work. Possible association between violence and a range of occupational, demographic, and lifestyle characteristics were studied. Stepwise multiple linear and logistic regressions were used to further examine risk factors for violence. Occupational factors with significant correlations to workplace violence were nursing discipline (type of ward or facility), years of work experience, supervisory responsibilities, night work, work dissatisfaction, work-related musculoskeletal injury, and frequency of patient handling. Demographic/lifestyle factors related to violence were age, gender, smoking, coffee consumption at work, and use of alcohol to relax after work. The best fit linear regression model explained 17% of the variance in violence, 13%, of the variance in threat of violence. The logistic regression model confirmed an increased risk of violence and threats in psychiatric and geriatric settings. However, much remains unexplained about the aetiology of violencc in health carc settings. This report provides the basis for a pilot intervention study currently in progress.  相似文献

Abstract

Positive psychology offers scope for enhancing satisfaction, motivation, and productivity in the workplace. Wiegand and Geller (2004, this issue) point to a number of strategies to enhance individuals' success orientation and conclude their discussion with the actively caring model which appears to be a useful means of representing pivotal facets of a positive and supportive workplace climate. The discussion in this article extends some of the concepts presented in their paper, adapts a model of motivation to develop the Occupational Motivation and Engagement Wheel, and also further discusses some particularly key strategies alluded to by Wiegand and Geller. These include a discussion of workplace resilience, authoritarian versus authoritative leadership/management styles, motivating workplace climates, personal bests, staff morale, flow in work, the value individuals attach to tasks and outcomes, and the centrality of relationships in the performance context. The article concludes with a multi-level “broaden and build” framework for enhancing satisfaction, motivation, and productivity in the workplace.  相似文献
