The effect of in-vehicle warning systems on speed compliance in work zones

The purpose of this research was to evaluate the effectiveness of augmented in-vehicle speed warnings on driver behavior in work zones. The influence of three device configurations were examined as the drivers entered a work zone which was presented in a simulated driving environment. The first configuration was a control condition which used only traditional signage. The second condition had the addition of a visual in-vehicle warning while the final condition had the addition of an auditory in-vehicle warning. Results indicated that adding in-vehicle warnings did affect driver compliance to the work zone speed limit. Participants in the audio warning condition responded more quickly to the warning than those in the visual condition. Both augmented warning configurations differed significantly and were each respectively different from the drivers in the control condition. Based on these results we suggest a combination of in-vehicle warnings. Upon entry of the work zone we suggest a combined audio and visual warning message. However, after the initial entry phase, a visual warning message shows greater promise for the on-going modulation of driver speed transit.     

Predicting the job and life satisfaction of Italian teachers: Test of a social cognitive model

This study tested a social cognitive model of work and life satisfaction (Lent & Brown, 2006, 2008) in a sample of 235 Italian school teachers. The model offered good overall fit to the data, though not all individual path coefficients were significant. Three of five predictors (favorable work conditions, efficacy-relevant supports, and positive affectivity) produced significant, direct paths to job satisfaction. Job satisfaction, progress at personal work goals, and positive affectivity were predictive of teachers' life satisfaction. Task self-efficacy was related indirectly both to job satisfaction (via work conditions) and life satisfaction (via goal progress). Implications of the findings for future research and efforts to promote teachers' job satisfaction are discussed.     

Social strategies during university studies predict early career work burnout and engagement: 18-year longitudinal study

This longitudinal study spanning 18 years examined the role of social strategies in early career adaptation. The aim was to find out whether individuals' social strategies measured during their university studies had an impact on work burnout and work engagement measured 10–18 years later. A sample of 292 university students completed the SAQ questionnaire three times while at university and the work burnout inventory three times and the work engagement inventory twice during their early career. According to the results, the higher the initial level of social optimism and the more it increased during university studies, and the lower the initial levels of social withdrawal and social handicapping and the more they decreased, the lower was the level of work burnout and the higher the level of work engagement in the early career. The effects of the level of social strategies were stronger on the professional efficacy subscale of burnout.     

Work demands and resources and the work–family interface: Testing a salience model on German service sector employees

The present study tested an extended version of Voydanoff's “differential salience vs. comparable salience model” in a sample of German service workers. Our findings partially support the model in a different national/cultural context but also yielded some divergent findings with respect to within-domain resources and boundary-spanning demands. In line with the theoretical framework, work-to-home interference (WHI) mainly occurred because of high work demands and not because of a lack of work resources. Boundary-spanning resources yielded comparable potential to reduce WHI and enhance work-to-home enrichment (WHE). WHE was expected to more likely occur due to the activation of work resources rather than the absence of work demands. However, control over one's work did not have a significant impact on WHE. In addition and contrary to the theoretical model, boundary-spanning demands were found to be differentially rather than comparably salient to the work–family interface.     

Evidence of construct validity for work values

Despite the importance of work values in the process of career adjustment (Dawis, 2002), little empirical research has focused on articulating the domains represented within the construct of work values and the examination of evidence of validity for the construct has been limited. Furthermore, the larger number of work values measures has made it difficult to determine the key domains that constitute the construct. The current study sought to examine multiple measures of work values to understand domains represented within the construct of work values and to establish evidence of validity for these domains. Principal Components Analysis utilizing scores on the Minnesota Importance Questionnaire (Rounds, Henley, Dawis, Lofquist, & Weiss, 1981), the revised edition of Super's Work Values Inventory (SWVI-R; Zytowski, 2006), and Manhardt's Work Values Inventory (Manhardt, 1972) found that six components best explained the data. These components reflected the importance of: the working environment, having challenging work, opportunities for status and income, autonomy, organizational support, and relationships. Implications for research and practice are discussed.     

Integrating work and basic values into the Spherical Model of Interests

Two prominent models of values, one in work and the other in life, were examined as they each related to the dimensions underlying the Spherical Model of Interests (Tracey & Rounds, 1996) as measured by the Personal Globe Inventory (PGI; Tracey, 2002). The technique of external property vector fitting was utilized to plot the value constructs onto two- and three-dimensional interest structures in a sample of 206 college students. Results, when compared across both theoretical and empirical definitions of interest space, indicated that all work values and fewer basic values related to two dimensions, but that only the work value of Achievement and the life value of Power related to the Prestige dimension. Implications for research and for assessment that involves integrating the results of values and interest inventories are discussed.     

Le collectif de travail : une protection pour la santé psychologique d’éducateurs d’ateliers industriels en milieu carcéral

Using data from a survey conducted in Psychodynamic of Work in a maximum security penitentiary with monitors of industrial workshops, this paper proposes an understanding of the impact of organizational constraints on the psychological health. This qualitative study shows that the situation faced by these workers produces significant sources of suffering for example, work prevented, oppositions between different groups of workers, rough social relationships, fears and dangers). Few sources of pleasure, based on the team relationship, the challenge of rehabilitation of prisoners and the satisfaction of making quality products. The study identified various defensive strategies to counter the suffering at work. Finally, the discussion focuses on the importance of collective work as a means of protecting psychological health.     

The relationship between perceived organizational support and work engagement: The role of self-efficacy and its outcomes

Introduction/objectiveThe objective of this study was to investigate the relationship between perceived organizational support and work engagement. On the one hand, we examined an underlying mechanism of this relationship, i.e. self-efficacy. On the other hand, we studied the outcomes of this relationship in terms of employees’ job satisfaction, psychological strains and performance.MethodAn online questionnaire was administrated to employees of two private companies. Employees’ performance was then evaluated by their direct supervisors. In total, 265 employees and 112 supervisors participated in the study.ResultsOur results indicated that self-efficacy partially mediates the relationship between perceived organizational support and work engagement. Furthermore, work engagement increased job satisfaction, reduced psychological strains and enhanced extra-role performance.ConclusionThis study contributes to the development of both work engagement literature and organizational support theory. The implications and limitations of this research are discussed in detail.     

The effects of virtual nature exposure on pro-environmental behaviour

Exposure to (virtual) natural environments may encourage people to care about environmental protection and to engage in pro-environmental behaviour. Previous research on this effect produced inconsistent results, suggesting that it may depend on the type of nature and behaviour under study. In the present study (N = 266), we investigated nature exposure effects on effortful pro-environmental behaviour in an online experiment. After watching pictures of either intact or destroyed natural environments, participants could exert voluntary extra efforts to generate real donations to an environmental organisation. In comparison to the intact nature condition, participants exerted significantly more effort for environmental protection after being exposed to pictures of destroyed nature. No clear differences were observed between the nature exposure conditions and a no-picture control condition. These findings illustrate the complexity of nature exposure effects and suggest that different types of nature exposure may differentially affect people's pro-environmental behaviour.
