An Optimal Solution for Enhancing Ambulance Safety: Implementing a Driver Performance Feedback and Monitoring Device in Ground Ambulances

This study investigated the effectiveness of auditory stimulation and performance feedback as fatigue countermeasures. Two types of auditory stimulation were used: (1) specially programmed music and (2) recordings of current news events. Two types of performance feedback came from (1) lateral position tracking and (2) speed tracking. It was hypothesized that each of the four countermeasures would significantly improve driver performance by reducing driver fatigue. Ten subjects were required to complete a series of three hour test sessions driving an automobile simulator. Each subject completed six control sessions without any of the countermeasures, followed by six experimental sessions utilizing one of the four countermeasures. Some subjects continued on with additional groups of six experimental sessions, each group with a different countermeasure. Dependent variables included lateral position error, speed variation, steering reversals, heart rate, and subjective fatigue. The results show that lateral position feedback was the only countermeasure that resulted in a consistent and significant improvement in driver performance. The results also suggest that early indications of speed variation and steering reversals are possible predictors of one's susceptibility to fatigue and poor performance during long distance driving, although further research is necessary.

The Impact

Background: The distribution of bulk fuel products to customers is one of the key activities in the downstream petroleum supply chain. For this activity to be effected successfully, three groups of supply chain participants, drivers, supervisors and customers, play key roles. Truck drivers are responsible for conveying the final product to the customer, whilst supervisors ensure that trucks are dispatched on time, driver performance is monitored and performance feedback is properly communicated to drivers. Customers, who purchase the final products, are the foundation of business success. Business success is only possible by meeting or exceeding customer expectations, and it is therefore imperative that the performance of employees is measured and monitored regularly.Objectives: This study was undertaken to determine the impact of measuring driver performance on the bulk fuel supply chain and on customer service.Method: A quantitative research methodology was conducted using structured questionnaires which were disseminated before and after the key performance indicators were implemented to three target groups.Results: The study found that the performance of drivers improved because of the performance feedback they received from supervisors who were perceived to have improved in their performance through the effective utilisation of key performance indicators, and as a result, this increased customer service levels.Conclusion: Whilst the research was limited to a single petroleum company, the results can provide management with guidance and insight on how to improve performance of employees through the use of key performance indicators, with a goal of providing excellent customer service.

Abstract. In five studies, we evaluated the psychometric properties of a revised German version of the State Self-Esteem Scale (SSES; Heatherton & Polivy, 1991 ). In Study 1, the results of a confirmatory factor analysis on the original scale revealed poor model fit and poor construct validity in a student sample that resembled those in the literature; thus, a revised 15-item version was developed (i.e., the SSES-R) and thoroughly validated. Study 2 showed a valid three-factor structure (Performance, Social, and Appearance) and good internal consistency of the SSES-R. Correlations between subscales of trait and state SE empirically supported the scale’s construct validity. Temporal stability and intrapersonal sensitivity of the scale to naturally occurring events were investigated in Study 3. Intrapersonal sensitivity of the scale to experimentally induced changes in state SE was uncovered in Study 4 via social feedback (acceptance vs. rejection) and performance feedback (positive vs. negative). In Study 5, the scale’s interpersonal sensitivity was confirmed by comparing depressed and healthy individuals. Finally, the usefulness of the SSES-R was demonstrated by assessing SE instability as calculated from repeated measures of state SE.

Reactions To Feedback

This paper focuses on explaining how individuals set goals on multiple performance episodes, in the context of performance feedback comparing their performance on each episode with their respective goal. The proposed model was tested through a longitudinal study of 493 university students’ actual goals and performance on business school exams. Results of a structural equation model supported the proposed conceptual model in which self-efficacy and emotional reactions to feedback mediate the relationship between feedback and subsequent goals. In addition, as expected, participants’ standing on a dispositional measure of behavioral inhibition influenced the strength of their emotional reactions to negative feedback.

Abstract. In the construction of scales intended for the use in cross-cultural studies, the selection of items needs to be guided not only by traditional criteria of item quality, but has to take information about the measurement invariance of the scale into account. We present an approach to automated item selection which depicts the process as a combinatorial optimization problem and aims at finding a scale which fulfils predefined target criteria – such as measurement invariance across cultures. The search for an optimal solution is performed using an adaptation of the [Formula: see text] Ant System algorithm. The approach is illustrated using an application to item selection for a personality scale assuming measurement invariance across multiple countries.
