title: A brief review of recent cyanobacteria monitoring results in the Waikato River

authors: Hamilton, David P.

subjects: New Zealand

abstract: Herewith is a report on possible reasons for low concentrations of cyanobacteria (blue-green algae) cells in the Waikato River in summer 2007-08 compared with previous records from 2003 to 2007. Because of time constraints, this report is a cursory consideration and does not provide the level of detail and analysis required to more fully evaluate phytoplankton succession as it relates to the complex interplay amongst physical, chemical and biological variables.
This report was requested by Mighty River Power following a summer when, as a result of drought conditions, the hydro system was operated in a manner similar to 2003, when cyanobacteria blooms(>15,000 cells mL⁻¹) occurred in the upper river and water temperatures were elevated. These operating conditions were characterised by maintenance of high water levels in the hydro dams and low inflows into the system, resulting in relatively long water residence times.

title: The association between mindfulness and driving behaviour in employees

authors: Bird, Diana

subjects: driving behaviour

abstract: This study examined the effect of mindfulness on driving behaviour, and the possible mediating effects of a number of well-being measures. Specifically, the research aimed to determine (1) if higher levels of mindfulness would lead to safer driving practices and (2) if there was a relationship between mindfulness and safe driving, whether this was mediated by well-being measures including self-control, emotion regulation, happiness, life satisfaction, job satisfaction and work engagement. Participants included 216 employees from 16 organizations. They all completed ‘the mindfulness, wellbeing and driving’ questionnaire, which involved measures of mindfulness, intentions to violate traffic rules, self-reported number of traffic incidences in the previous 12 months (fines, near misses and crashes), as well as the well-being measures mentioned above. First, a strong correlation between increased levels of mindfulness and safer driving practices was found, including a decreased likelihood of texting. Further initial correlations also demonstrated relationships between mindfulness and all the well-being measures. As mindfulness increased, levels of all the well-being measures increased, with the exception of happiness. However, when mediation analysis was performed only self-control and happiness were found to mediate the relationship between mindfulness and safer driving, while the effect of emotion regulation, life and job satisfaction and work engagement were not found to be significant mediators. The role of self-control as a mediator in the mindfulness safer driving relationship supported previous research. Increased levels of attention, awareness and emotion regulation are all qualities associated with increased levels of mindfulness, which have also been demonstrated to relate to safer driving practices.
While happiness was found to positively mediate the relationship between mindfulness and safer driving practices, interestingly, the relationship between mindfulness and happiness was opposite to what was expected. As levels of mindfulness increased, levels of happiness decreased. This may have been due to the happiness measure, which contained eudaimonic and hedonic factors. Hedonic factors have been considered less indicative of life satisfaction and overall well-being, and run opposite to the principles underlying mindfulness. Despite this, increased levels of happiness were still found to increase safer driving practices. These findings will hopefully ignite more research efforts to be directed towards examining the effects of mindfulness interventions on driving practices, and overall social and occupational well-being.
