Test of a social cognitive model of work satisfaction in teachers

Lent and Brown [Lent, R. W., & Brown, S. D. (2006). Integrating person and situation perspectives on work satisfaction: A social-cognitive view. Journal of Vocational Behavior,69, 236-247] recently proposed an integrative model of work satisfaction linked to social cognitive career theory. The model posits that work satisfaction is predicted by five classes of variables: work conditions, goal progress, self-efficacy, goal and efficacy relevant supports, and personality traits (e.g., positive affect). We tested this model in a sample of 366 teachers, finding good overall model-data fit. Of the five predictor classes, work conditions, self-efficacy, and positive affect were each found to explain unique predictive variance. This suggests that teachers who are most satisfied with their jobs see their work environment as supportive, are confident in their abilities to complete work-related tasks and goals, and report high levels of trait positive affect. Findings also offered support for the contention that measures of subjective person-environment fit may not be empirically distinct from work satisfaction. Implications of these findings for future research and applied efforts are considered.     

Analysis of the factors affecting drivers’ queue-jumping behaviors in China

In China, drivers’ queue-jumping behaviors are very common. To explore the factors affecting drivers’ queue-jumping, first, a driving attitude scale, a risk perception scale and a queue-jumping behavior scale were designed, and an existing Type A behavior pattern scale and a driver skill scale were also introduced. Second, these scales were used to collect empirical data, and 202 valid samples were obtained. Third, the reliability and validity of the developed scales were verified, and a structural equation model of drivers’ queue-jumping behaviors was established to explore the interrelationships among the Type A personality trait, cognitions (including attitudes and risk perception), driver skills (including driving skill and safety motivation) and queue-jumping behaviors. The results showed that drivers’ cognitions significantly affected their queue-jumping behaviors; specifically, drivers’ attitudes toward queue-jumping and traffic violations positively correlated with their queue-jumping behaviors (β = 0.323, t = 3.470; β = 0.277, t = 3.072), while drivers’ risk perception toward queue-jumping negatively correlated with their queue-jumping behaviors (β = −0.297, t = −3.889). Drivers’ driving skill and safety motivation also significantly affected their queue-jumping behaviors (β = 0.198, t = 2.385; β = −0.355, t = −4.101). Although Type A personality trait had no significant effects on drivers’ queue-jumping behaviors, it had significant effects on drivers’ attitudes toward queue-jumping and traffic violations (β = 0.336, t = 4.720; β = 0.215, t = 2.873) and their risk perceptions toward queue-jumping (β = −0.232, t = −3.279). In other words, the Type A personality trait can indirectly affect drivers’ queue-jumping behaviors through drivers’ attitudes and risk perceptions toward queue-jumping. The results provided offer traffic administration departments a theoretical foundation for governing this behavior.     

A qualitative study of young drivers and deterrence based road policing

Deterrence theory is the predominant theory used to underpin road policing initiatives. However, survey research indicates that this approach may not be as effective for young drivers. This study uses focus groups, conducted in both metropolitan and regional locations in two Australian states (Queensland and Victoria), to explore three components of classical deterrence theory: certainty, severity & swiftness. The results suggest that geographical context affected perceptions of certainty with individuals from regional locations less likely to indicate that they would be caught by police for committing a traffic offence. Additionally, the use of cameras to detect road offences increased perceptions of certainty for young drivers. The results of this study suggest that police agencies should focus on undertaking actions to increase the perceptions of certainty swiftness and severity of punishment, particularly in regional areas, for young drivers who engage in illegal behaviour on the road. Where appropriate, these actions should take into account the geographical context. There may also be value in considering augmenting deterrence theory with other theoretical perspectives for this group.     

The Motorcycle Rider Behavior Questionnaire: Psychometric properties and application amongst novice riders in Australia

The Motorcycle Rider Behavior Questionnaire (MRBQ) was developed to measure behavioral factors influencing motorcyclists’ crash risk including errors and violations as well as the use of motorcycle safety equipment via self-report. The aims of the present study were to (1) examine the previously examined psychometric properties of the MRBQ including the factor structure, internal consistency, and predictive validity in terms of self-reported crashes amongst experienced riders in the UK and Turkey; (2) examine the psychometric properties of the MRBQ not yet examined, including its stability, content validity, and predictive validity in terms of police-recorded crashes and offences as well as self-reported near crashes and crashes; and (3) assess the applicability of the MRBQ to a population of novice riders in Australia, to whom the MRBQ has not been applied to date. Novice riders (N = 1305) in the state of Victoria, Australia participated in the present study. Confirmatory factor analyses showed that the present data did not fit with the previously found factor models in experienced riders in the UK and Turkey. Principal axis factoring was performed to respecify the MRBQ factor model amongst novice riders and revealed four scales: errors; speed violations; stunts; and protective gear. The insufficient internal consistency, stability, content and predictive validity demonstrated by the MRBQ in the present study and some inconsistencies amongst the three MRBQ studies suggest that the development and refinement of the MRBQ items are required before wider use of the MRBQ instrument, especially amongst novice riders. Possible causes of the limited reliability and validity of the current MRBQ are discussed to inform further development and refinement of the items, thereby making the MRBQ more useful in future research to understand and evaluate riders’ behaviors.     

Development and validation of an instrument for assessing job demands arising from accelerated change: The intensification of job demands scale (IDS)

Accelerated societal and organizational changes have placed new pressures on employees. Especially, service employees are exposed to intensified workloads, planning and decision-making, and learning demands. Despite the growing attention given to this intensification of job demands, a comprehensive measure is missing. In the present study, we developed the Intensification of Job Demands Scale (IDS) and validated it in four samples (N = 1363). Confirmatory factor analyses supported the differentiation into five subscales, namely work intensification, intensified job-related planning and decision-making demands, intensified career-related planning and decision-making demands, intensified knowledge-related learning demands, and intensified skill-related learning demands. This five-factor structure holds for both the German and the English versions of the instrument. Convergent and discriminant validity tests showed that the IDS subscales are moderately related to established measures of job demands, but at most have small correlations with negative affectivity. Providing support for the incremental validity, the IDS subscales were found to add to the prediction of burnout and job satisfaction beyond established job demands. Finally, the IDS subscales helped to identify employees who experienced changes in their work situation. In sum, the results indicate that the IDS is a valid and reliable measure to assess the intensification of job demands.     

Effects of Mediated Learning Experience,Tutor Support and Peer Collaborative Learning on Academic Achievement and Intellectual Functioning among College Students

If the practice of psychology is to be relevant to environmental realities and context sensitive then conscious consideration must be given to the psychology training programme. Training programmes should give due recognition to the historical, political, social, economic and cultural contexts of human behaviours so as to understand how these interacting contexts may contribute to placing people at risk for ill-health. The main aim of this article is to present an analysis of African environmental realities to which training programmes in psychology must respond. In view of the under-utilization of psychological services within healthcare systems in many parts of Africa, this article also provides some suggestions for the development of appropriate training and practice modalities that may be geared towards effective healthcare service delivery in Africa.     

Does the effect of traffic calming measures endure over time? – A simulator study on the influence of gates

Accident statistics show that transitions from rural to urban areas are accident prone locations. Inappropriate speed and mental underload have been identified as important causal factors nearby such transitions. A variety of traffic calming measures (TCM) near rural–urban transitions has been tested in field experiments and driving simulator studies. Simulator experiments repeatedly exposing participants to the same treatment are scarce, hence it is unclear to what extent the effects of a TCM endure over time.This is precisely the objective of the current study: to examine what happens with the behavior of drivers when they are exposed multiple times to the same treatment (in this case a gate construction located at a rural–urban transition). Over a period of five successive days, seventeen participants completed a 17 km test-drive on a driving simulator with two thoroughfare configurations (gates present or absent) in a within-subject design. Results indicate that gates induced a local speed reduction that sustained over this five-day period. Even though participants were inclined to accelerate again once passed by this gate configuration, they always kept driving at an appropriate speed. We did not find any negative side effects on SD of acceleration/deceleration or SDLP.Overall we conclude that gate constructions have the potential to improve traffic safety in the direct vicinity of rural–urban transitions, even if drivers are repeatedly exposed. Notwithstanding, we advise policy makers to appropriately use this measure. Best is to always carefully consider the broader situational context (such as whether the road serves a traffic- rather than a residential function) of each particular location where the implementation of a gate construction is one of the options.     

The influence of fatalistic beliefs and risk perceptions on road safety attitudes in Latin America; A two-country study

Road safety is a major challenge in the Latin American region; however, there is a significant lack of research undertaken there. To contribute to addressing this gap, this paper reports on an exploration of the antecedents of traffic safety attitudes in two Latin American contexts: Brazil and Ecuador. Building on related work undertaken in other countries, the research explored the relationships between fatalistic beliefs, traffic risk perceptions, and road safety attitudes, while accounting for age, gender, and exposure to the road environment. Data from 2432 individuals, analysed using Structural Equation Modelling, revealed differences in the extent to which different fatalistic belief constructs (including divine control, luck, helplessness, internality, and general fatalism) were related to road safety attitudes. Moreover, fatalistic beliefs were found to influence road safety attitudes both directly and indirectly through their influence on risk perceptions. Those that reported more fatalistic beliefs also reported more dangerous attitudes to road safety and a lower perception of on-road risk. Mirroring findings from work undertaken in other countries, we found males compared to females and younger compared to older respondents to report more dangerous attitudes to road safety, with inconclusive results for risk perceptions. We also found very similar patterns of results in the data from the two countries included in the research. Results are discussed with regards to informing the design of road safety interventions aimed at influencing individual road user attitudes and, ultimately, human behaviour and system performance.     

Behavioral adaptations of human drivers interacting with automated vehicles

Advancements in technology are bringing automated vehicles (AVs) closer to wider deployment. However, in the early phases of their deployment, AVs will coexist and frequently interact with human-driven vehicles (HDVs). These interactions might lead to changes in the driving behavior of HDVs. A field test was conducted in the Netherlands with 18 participants focusing on gap acceptance, car-following, and overtaking behaviors to understand such behavioral adaptations. The participants were asked to drive their vehicles in a controlled environment, interacting with an HDV and a Wizard of Oz AV. The effects of positive and negative information regarding AV behavior on the participants’ driving behavior and their trust in AVs were also studied. The results show that human drivers adopted significantly smaller critical gaps when interacting with the approaching AV as compared to when interacting with the approaching HDV. Drivers also maintained a significantly shorter headway after overtaking the AV in comparison to overtaking the HDV. Positive information about the behavior of the AV led to closer interactions in comparison to HDVs. Additionally, drivers showed higher trust in the interacting AV when they were provided with positive information regarding the AV in comparison to scenarios where no information was provided. These findings suggest the potential exploitation of AV technology by HDV drivers.     

Analysing driver’s decision in dilemma zone at signalized intersections under disordered traffic conditions

Delay in the decision-making process of stop or go during the amber phase of the signal cycle often leads to abrupt hard deceleration or red light violations at signalized intersections. The indecisiveness or the dilemma in decision making often results in compromised safety of the road users. The present study attempts to analyze the driver’s behaviour in order to make the decision of stop or go and developed a binary logistic regression model while considering different traffic behaviour parameters exhibited and observed after the onset of the amber phase. Empirical vehicular trajectory data from three signalized intersections covering 121 signal cycles and 1347 vehicles are used in the study. The study presents two dilemma zone identification models based on distance from the stop line, focusing on easy-to-use and static driver assistance and dynamic-realtime driver assistance systems. Both the models are observed to show good fit and prediction accuracy. The models are validated internally and externally for their adaptability in the field. The effect of different traffic parameters on the dilemma zone is explored, and a possible real-time application of the dynamic model as a driver assistance system in decision-making is explored.
