Fathers' work experiences,the father-child relationship and children's behaviour

The effects of fathers' subjective work experiences on their children's behaviour have been largely neglected, despite increasing recognition accorded to the fathers' role in all aspects of child development. The present study redresses this issue by assessing whether (a) fathers' work experiences are related to children's behaviour, (b) the father-child relationship moderates the effects of fathers' work experiences on children's behaviour, and (c) specific child behaviours are associated with paternal work experiences. One hundred and forty two fathers (M age = 39.55 years) and their eldest child (M age = 9.2 years; 66 boys, 76 girls) participated. Moderated multiple regressions demonstrated that fathers' job satisfaction was related to specific child behaviours, viz. conduct problems and hyperactivity. More importantly, the father-child relationship moderated both these relationships: Where fathers were dissatisfied with their jobs, conduct problems and hyperactivity were significantly greater when the father-child relationship was of a higher quality. Implications for studying the effects of both mothers' and fathers' work experiences on their children's behaviour are drawn.     

The effects of personal music devices on pedestrian behaviour

It has been suggested that pedestrians listening to personal music devices (PMD) are more likely to be involved in accidents than those not listening to PMDs. Though it has been demonstrated that pedestrians on cell phones exhibit less cautionary behaviour when street crossing ( [Hatfield and Murphy, 2007], [Nasar et al., 2008] and [Stavrinos et al., 2009]), little research has been conducted with PMD users. In the present study, cautionary behaviour (e.g., looking before crossing a road) was observed and recorded for pedestrians with or without PMDs. Amongst males, pedestrians listening to PMDs displayed more looking behaviour than those not listening to PMDs. Females showed no differences between the two conditions. Thus, unlike cell phones, PMDs do not decrease the cautionary behaviour of pedestrians. This suggests that cell phones and PMDs are two different types of distractions, and this needs to be taken into account when developing methods to prevent pedestrian accidents in the future.     

Psychological success and the boundaryless career

The boundaryless career could be a bane or boon to people's experience of psychological success. This paper describes the contours of the boundaryless career and then looks at how workers will have to deal with aging over several career cycles, integrate diverse experiences into their identities, and come to terms with new types of employer-employee relationships. This introduces the idea of finding psychological success in one's life work, encompassing not only a job and an organization, but also work as a spouse, parent, community member, and as a self-developer.     

The relationship between job experiences and psychological distress: A structural equation approach

Using structural equations, we estimated the relationship between employees' experiences of seven job conditions, that have been identified as potential job stressors, and psychological distress in a random sample of 504 full-time employed men and women in dual-earner couples. The seven job conditions were: skill discretion, decision authority, schedule control, job demands, pay adequacy, job security, and relations with supervisor. We found that two job conditions — skill discretion and job demands — were related to psychological distress, whereas five other conditions were not. These findings lend partial support to Karasek's job demand — job control model. In our analysis, skill discretion, one of the two components of job control (referred to jointly as decision latitude) was related to distress, however, decision authority, the second component, was not. A third aspect of control, schedule control, was also unrelated to distress. For full-time employed women and men in dual-earner couples, the additive effects of feeling concerned about having to do dull, monotonous work and having to work under pressure of time and conflicting demands were associated with psychological distress. Finally, the magnitude of the relationships between these job experiences and psychological distress did not differ between men and women.     

Maternal employment experiences,attention problems and behavioral performance: A mediational model

The present study posits and empirically tests a process model examining the effects of interrole conflict, satisfaction with, and commitment to the role of employed mother on a self-report measure of cognitive difficulties and a behavioral measure relevant to work performance (proof reading). Fifty-three full-time employed mothers with at least one child living at home participated. The proposed model, tested using Lisrel VI, provided an excellent fit to the data. Specifically, interrole conflict exerted an indirect effect on proof reading performance, mediated by self-reported attention and concentration difficulties. Satisfaction with and commitment to the role of employed mother were not related to either proof reading performance or self-reported cognitive difficulties.

Accident risk and driver behaviour

The concepts of risk compensation and risk homeostasis are often used to describe or to explain drivers' tendencies to react to traffic system changes whether in roads, vehicles, weather conditions or in their own skills. However, it is important to distinguish between the general phenomenon and mechanisms underlying it. This paper first points out that to understand the basic mechanisms it is necessary to split accidents and exposure into smaller entities to arrive at basic units of exposure which also represent fundamental driver tasks. Risk-related behaviour should be considered at several hierarchical levels with different mechanisms to produce ‘risk compensation’. At a high level, trip decisions modify populations at risk in different circumstances, sometimes attenuating, sometimes amplifying population risk differences. At a low level of vehicle control and guidance in real dynamic traffic situations, simpler control mechanisms which result in behavioural adaptation can be identified. All these effects influence the end result of accident risk as separate mechanisms.

Some experiences in hazard identification and risk shortlisting

‘Rapid ranking’ has been used for many years as a method of determining the priority which should be given to formal investigation of the wide range of hazards and risks present on major process industry sites. Such methods tend to evolve to meet the needs of specific applications. Some historical and recent applications are outlined, and the nature of the developments which they led to are discussed. Particular topics discussed include: development of the method such that it is usable by operating managers rather than specialists; use to raise risk consciousness; adaptation for use as an aid to hazard identification; use to define both which risks should be studied and which risks, even if low, should be incorporated in routine monitoring and periodic auditing programmes; use as a basis for comparison of the relative risks presented by a variety of different industrial installations; use for a range of different types of risk; and extension beyond ranking to include ‘shortlisting’ i.e. deciding which risks to include in a study programme and which to leave out. Philosophical difficulties with the approach are discussed, including the danger of omitting from detailed study a risk which is erroneously shown as low, and the uncertainty of the absolute level of the ranked risks. Approaches to minimizing these problems are discussed.     

Two experiences on education and training in dry-cleaners

The aim of the study was to evaluate which training method was more useful for employers of small enterprises concerning occupational health and safety.Therefore, we decided to involve the dry-cleaner employers' associations of our town in a project of educational meetings with the employers, before making repressive inspections.In 1989, 43 dry-cleaners were then inspected and the data obtained about occupational risks were discussed in these meetings, in order to explain to the employers meaning and necessity of adopting the correct preventive measures provided for by the law. A second inspection was carried out some months later, in 1990, to check the effectiveness of the meetings. In 19 out of 43 dry-cleaners (44%) the lack in risk prevention, discovered in 1989, was not, or only in part, eliminated. Therefore, we thought to act towards the remaining dry-cleaner employers in a different way: (a) on the basis of the previous inspections, we produced a handbook easy to understand and rich in information about occupational risks in dry-cleaning and how to avoid them; (b) in 1992 our educational staff executed training inspections in 67 other dry-cleaners, together with employers and workers. They distributed the handbooks and, at the same time, gave some practical example of solution for safety problems. In 1993, in 25 (randomly selected) out of the 67 dry-cleaners, a inspection was carried out to check on: adoption of correct environmental prevention measures, correct utilization of personal protective equipment, execution of correct medical surveillance. Law violations were proportionally much lower (e.g., omitted or inadequate forced air DRAWING = 36%) than those found in the first inspection of 1989 (e.g., omitted or inadequate forced air DRAWING = 86%).Although other causes could interfere, it is possible that this result is connected to the last training method, that is more time-consuming but awakens the employers of small enterprises to the risks for health and safety and to act accordingly.     

Ensuring patient safety through effective leadership behaviour: A literature review

Ensuring patient safety has always been important for critical care teams. Since team and leadership skills are increasingly recognised as important for the patient’s safety, a body of literature on leadership in critical care has emerged. The purpose of this paper is to provide a systematic review on the findings of effective leadership strategies in critical care teams. We aim to contribute to a better understanding of factors influencing leadership behaviour that in turn effect team outcomes. An input–process–output model of leadership is used to systemise the findings. The results of this review clearly show that effective leaders play a pivotal role in promoting team performance and safety. Effective leadership is characterized by clear and unambiguous behaviour which is adaptable to situational demands and shared between team members. The review concludes with recommendations for future research directions.

A geographical perspective on driving attitudes and behaviour among young adults in urban and rural Norway

Studies have shown that the driver’s risk behaviour is a significant contributor to the difference in road traffic accident risk between urban and rural areas. The aim of the study is to achieve a better understanding of the relatively high risk for rural youths compared to urban youths. A cross-sectional survey with 484 drivers aged 19–24 years is used to compare self-reported risk behaviour in urban, peri-urban and rural areas. A stratified random sample was made to ensure respondents from different area types. The results show an urban–rural gradient in risk-taking behaviour. Attitudes towards road safety partly explain individual variation in risk behaviour; however, they fail to erase the urban–rural gradient. The findings suggest a complex interaction of the system risk (the road environment) and elements of risk-culture beyond road safety attitudes.     

Innovations and personal change: Patterns of adjustment to relocation

The aim of the study was to test hypotheses derived from Nicholson's (1984) theory of work-role transitions within the context of job relocation. These hypotheses concern the adjustment strategies used by those changing jobs. A total of 121 U.K. employees provided data at three points in time during the process of their relocation. Measures included job characteristics, personal change, role innovation, self-esteem and subjective well-being. Data were analysed via non-recursive structural equation models using LISREL VI. Results were generally consistent with the model of work-role transitions. Individual differences in self-esteem were found to influence adjustment strategies over and above the effects of job characteristics.

A model of the antecedents of early union commitment: The role of socialization experiences and steward characteristics

The present study aimed at investigating the influence of shop steward characteristics and early union socialization experiences on new members' attitudes toward unions and their affective commitment to the union. Two thousand surveys were mailed to the most recent members of the National Association of Letter Carriers. Of these, 658 (33 per cent) were returned. Focusing on those individuals who had joined the union within the past 12 months yielded a usable sample of 585. A two-stage, structural equation modeling approach indicated a satisfactory goodness-of-fit for both the measurement and structural models. Individual socialization experiences significantly affected union attitudes. The latter variable was a significant predictor of union commitment. These results are discussed in the context of the organizational socialization literature and union commitment research.
