Causes of accidents and the time of day

Abstract

The relationship between accidents and the time of day is not entirely clear. Although there is considerable evidence that performance is poorest in the early morning hours compared to at all other times, the degree to which this is translated into accidents is not understood. In this study work-related fatal accidents were analysed to determine whether the causes of these accidents vary with time. The analysis used a classification and coding system devised to describe the wider circumstances of the causes of fatalities. In terms of absolute numbers, fatalities were most common in the late morning or early afternoon. When these results were expressed in terms of the estimated number of workers at work, the proportion of fatal accidents occurring at night was more than double that occurring during the day. Behavioural factors were the most common cause of fatalities at all times, but most common in the early hours of the morning. Further analysis of the nature of the behavioural involvement showed that errors in automatic processing (skill-based errors) were the most common types of error and did not vary much with time of day. Rule-based errors were most common during the day whereas knowledge-based errors occurred mainly in the afternoon and night shifts. These results cast some doubt on the assumption that there is a direct relationship between the previously observed variations in performance across time and the ultimate safety outcome.     

Key personality traits of engineers for innovation and technology development

Focusing on new roles of engineers for technological innovation and internal entrepreneurship, we examined the personality traits of 4876 engineers versus 75,892 non-engineers. Engineers scored higher on Tough-Mindedness and Intrinsic Motivation; but lower on Assertiveness, Conscientiousness, Customer Service Orientation, Emotional Stability, Extraversion, Image Management, Optimism, Visionary Style, and Work Drive. All but four of these traits were positively related to engineers’ career satisfaction. Overall, the results are not encouraging for the new roles of engineers such as intrapreneurship. Findings were discussed in terms of occupational profiling of engineers as well as career planning, selection, training, and professional development of engineers.     

Work and rest in the long-distance road transport industry in Australia

To date management of fatigue in professional drivers has largely focused on strategies that limit the amount of time spent on the job. These approaches have, however, not taken into account the well-documented effect of time of day. Consequently, the likely impact of the pattern and timing of work and rest has received little attention. The results revealed that the group of drivers who did the shortest trips and worked the shortest weekly hours were the lowest reporters of fatigue, although longer hours were not always associated with the highest reporting of fatigue. In contrast, the shortest working hours were associated with earliest onset of fatigue. For all drivers, the influence of circadian rhythms was evident in the occurrence of fatigue, with better management of the problem evident among drivers who were able to arrange the timing of rest to more closely coincide with periods of fatigue. Thus, time of day appeared to be a more important influence in determining effective rest than did period of work. These findings raise questions about the validity of the assumption underlying work hour regulations for long-distance drivers which, currently, are universally based on duration of work.     

Do universal non‐contributory old‐age pensions make sense for rural areas in low‐income countries?

The need for old‐age security coverage in rural areas of many developing countries is rapidly increasing for several reasons, including population ageing and the weakening of family support networks. These trends have generated intense interest in policies that might help respond to the growing problem of rural old‐age destitution. The focus of our analysis is on one of the most promising alternatives under consideration: universal non‐contributory old‐age pensions. This model has some limitations and it is not appropriate for all developing countries, but it would be of potential benefit to far more than the six that have already implemented variants of this approach.     

Patients First — Reality or Rhetoric?

This paper will argue that the NHS, despite its aspirations to provide a universal service of excellence, has not been historically very responsive to the consumers it serves. Under the present Government this attitude has ostensibly changed. “Patients First” has become a catch phrase both nationally and at the local level in Brighton Health District. A recent CHC survey of consumers' rections to service revealed however that many elderly patients were not consulted in any meaningful way about their needs on discharge from hospital. Why does the reality of consumerism not match the rhetoric? A number of potentially explanatory factors are identified and their relevance evaluated in the context of Brighton CHC's research. It is suggested that the currently fashionable consumerism represents a different concept from active participation which would necessarily involve a fundamental realignment of the NHS.     

PERSONAL AUTHORITY VIA TERMINATION OF THE INTERGENERATIONAL HIERARCHICAL BOUNDARY: PART II—THE CONSULTATION PROCESS AND THE THERAPEUTIC METHOD

This paper is by way of a continuation of the definition of the theoretical position on the termination of the intergenerational hierarchical boundary, presented earlier (Williamson, 1981). That paper argued that this termination requires "a radical renegotiation of the power structures in the relationships between the two generations, and in the interactional political patterns which ensue from these." This paper reports on and describes a therapeutic methodology for securing and completing such a "radical renegotiation." It is implied that this therapeutic procedure has widespread applicability to the resolution of behavioral problems.     

Academic incentives for students can increase participation in and effectiveness of a physical activity program

The authors sought to determine whether a greater academic incentive would improve the effectiveness and student adherence to a 12-week voluntary exercise program designed to decrease students' percentage of body fat. They randomly assigned 210 students to 1 of 2 groups with different academic reward structures. The group with the greater reward structure showed better exercise adherence and lost more body fat than those without the additional incentive. These findings suggest that an academic incentive can increase overall student adherence to a voluntary exercise program and can boost the effectiveness of the program in a university environment. The findings also have potential implications for on-campus promotion of physical activity.     

PERSONAL AUTHORITY IN FAMILY EXPERIENCE VIA TERMINATION OF THE INTERGENERATIONAL HIERARCHICAL BOUNDARY: PART III—PERSONAL AUTHORITY DEFINED, AND THE POWER OF PLAY IN THE CHANGE PROCESS

Present transgenerational family therapy theory is analyzed, and it is suggested that individuation is on a continuum with fusion-triangulation (family systems theory), that relational ethics are on a continuum with invisible loyalties (contextual family therapy), and that there is in fact but one continuum, so that these terms are well-nigh interchangeable. Individuation-relational ethics is presented in a (Hegelian) dialectic with intimacy; and personal authority in family experience is offered as the synthesizing construct in this dialectic. The change process in transgenerational family therapy is briefly noted. It is suggested that playfulness, including paradox and absurdity, is an effective intervention into the intense emotionality of inter generational work. A framework for and sequence of playful interventions are described.
