Teaching HRD personnel : experiences of computer-mediated communication in differently structured environments

This paper will provide an overview of the CMC structure in two different units of study in the Masters of Professional Education and Training at Deakin University. Each of these structures makes a set of demands on participants, and provides differing collaborative learning opportunities. The paper examines the experiences we have had in each of these structures, focusing on student participation, style of contribution to CMC, and the relationship between socialisation processes and knowledge construction.

Officer wellbeing, satisfaction and commitment : job conditions of Australian law enforcement personnel

Excessive job stress caused by unreasonably high employer demands, low control over one's own work and limited support can have far-reaching effects for the individual, organisation and community. The present study sought to investigate the relationship between officer working conditions and their self-reported levels of wellbeing, satisfaction and commitment using a well-known job strss model, the demand-control-support (DCS) model. Using a large (N= 2085) sample of law enforcement personnel, findings indicated that social support from work sources was the best predictor, whilst job control and workload both had significant influences on levels of employee wellbeing, satisfaction and commitment. Additionally, non-linear relationships were found between workload and wellbeing and satisfaction, indicating that both high and low levels of workload can produce negative outcomes. The results have implications for job design and management training programs, particularly in reference to social support training and workload models.

Using job strain and organizational justice models to predict multiple forms of employee performance behaviours among Australian policing personnel

The overall purpose of this investigation was to examine the relationship between stress-related working conditions and three forms of employee performance behaviours: in-role behaviours, citizenship behaviours directed at other individuals and citizenship behaviours directed at the organization. The potentially stressful working conditions were based on the job strain model (incorporating job demands, job control and social support) as well as organizational justice theory. A sample of Australian-based police officers (n = 640) took part in this study and the data were collected via a mail-out survey. Multiple regression analyses were undertaken to assess both the strength and the nature of the relationships between the working conditions and employee performance and these analyses included tests for additive, interactional and curvilinear effects. The overall results indicated that a significant proportion of the explained variance in all three outcome measures was attributed to the additive effects of demand, control and support. The level of variance associated with the organizational justice dimensions was relatively small, although there were signs that specific dimensions of justice may provide unique insights into the relationship between job stressors and employee performance. The implications of these and other notable findings are discussed.

L’implication des missionnaires pentecôtistes dans l’aide au développement en Asie du Sud-Est

A noticeable shift has been recently observed in Western-based Pentecostal mission agencies’ activities in mainland Southeast Asia. Where once these organizations avoided a visible priority on social justice as being at odds with their understanding of mission, the funding for and implementation of such programs has increased dramatically for the last two decades. This shift in focus is best understood by considering the motivations for this work and the perceived differences between evangelism and development work. This paper explores the motivations of these agencies for engaging in international development, and in particular the extent to which development programs are seen by these agencies as a strategy for proselytization and the extent to which they are conducted out of other humanitarian motivations. The research is based on a phenomenological literature survey and new interview data exploring development operations of western-based Pentecostal mission organizations in mainland Southeast Asia. Analysis of these data challenges preconceived notions of a distinction between motives of evangelism and humanitarian concern.

The effectiveness of health interventions in cardiovascular risk reduction among emergency service personnel

Purpose
The physical demands and hazards associated with emergency service work place particular stress on responders’ cardiovascular systems. Indeed, cardiovascular disease (CVD) is a significant problem for emergency service personnel. Although it may be difficult to alter the cardiovascular health hazards associated with the work environment, it is possible for personnel to control their modifiable CVD risk factors, cardiovascular fitness levels and subsequently, reduce their CVD risk. This review aimed to determine the effectiveness and methodological quality of health interventions designed to mitigate CVD risk in emergency service personnel.

Methods
A literature search of electronic journal databases was performed. Sixteen relevant studies were assessed for methodological quality using a standardised assessment tool. Data regarding the effectiveness of each intervention were extracted and synthesised in a narrative format.

Results
Fifteen studies were rated ‘Weak’ and one study was rated ‘Strong’. Interventions which combined behavioural counselling, exercise and nutrition were more effective in improving cardiovascular health than nutrition, exercise or CVD risk factor assessment-based interventions alone. Further, CVD risk factor assessment in isolation proved to be an ineffective intervention type to reduce CVD risk.

Conclusion
Combined interventions appear most effective in improving the cardiovascular health of emergency service personnel. Accordingly, fire and emergency service agencies should consider trialling multifaceted interventions to improve the cardiovascular health of personnel and avoid interventions focused only on one of nutrition, exercise or CVD risk factor assessment. However, as most studies were methodologically weak, further studies of a higher methodological quality are needed.

Effects of work-related sleep restriction on acute physiological and psychological stress responses and their interactions: A review among emergency service personnel

Emergency work can expose personnel to sleep restriction. Inadequate amounts of sleep can negatively affect physiological and psychological stress responses. This review critiqued the emergency service literature (e.g., firefighting, police/law enforcement, defense forces, ambulance/paramedic personnel) that has investigated the effect of sleep restriction on hormonal, inflammatory and psychological responses. Furthermore, it investigated if a psycho-physiological approach can help contextualize the significance of such responses to assist emergency service agencies monitor the health of their personnel. The available literature suggests that sleep restriction across multiple work days can disrupt cytokine and cortisol levels, deteriorate mood and elicit simultaneous physiological and psychological responses. However, research concerning the interaction between such responses is limited and inconclusive. Therefore, it is unknown if a psycho-physiological relationship exists and as a result, it is currently not feasible for agencies to monitor sleep restriction related stress based on psycho- physiological interactions. Sleep restriction does however, appear to be a major stressor contributing to physiological and psychological responses and thus, warrants further investigation.

Occupational stress and job satisfaction in media personnel assigned to the Iraq War (2003)

This paper investigates occupational stressors amongst media personnel assigned to work on covering the Iraq War via interviews with 54 journalists from the BBC and Reuters, who worked in Iraq between February and April 2003. A range of stressors were identified that could be categorized into three main themes, control over the situation, support from management and grief from the death of colleagues. Journalists not embedded with military units were more likely to report negative physical and emotional health outcomes. The study concludes that hazardous work environments do not, by themselves, cause stress and poor job satisfaction. Rather, organizational factors, the imbalance between the ability to make decisions about how to carry out their job effectively and the perceived rewards of working in such environments appear to have a greater impact on work related stress.
