- This study investigates whether increasing levels of job autonomy are linearly associated with improved psychological well-being, or whether the association is non-linear with higher levels of job autonomy being negatively associated with psychological well-being. The study is based on a survey in 4,340 individuals. After six months a follow-up survey was conducted. Associations were analysed using spline models in cross-sectional and prospective analyses of the full study population. We stratified the study population in four types of work for further cross-sectional analyses. The cross-sectional analysis of the full study population indicated a non-linear relationship as the association attenuated but remained positive at all levels of job autonomy. The prospective analysis indicated a positive linear association. The stratified cross-sectional analyses indicated a linear association in three of the four types of work and a non-linear but positive association among respondents in client-related work. Findings are supported in sensitivity analyses using alternative outcomes: vigour, job satisfaction and work stress. We conclude that job autonomy is positively associated with psychological well-being. Findings have relevance for job redesign by indicating that higher levels of job autonomy are beneficial for the psychological well-being of workers – especially among workers with low levels of job autonomy.

- The vertical distribution of copepods, fecal pellets and the fecal pellet production of copepods were measured at seven stations across the Southern Indian Ocean from productive areas off South Africa to oligotrophic waters off Northern Australia during October/November 2006. We quantified export of copepod fecal pellet from surface waters and how much was retained. Furthermore, the potential impact of Oncaea spp. and harpacticoid copepods on fecal pellets degradation was evaluated and found to be regional substantial. The highest copepod abundance and fecal pellet production was found in the western nutrient-rich stations close to South Africa and the lowest at the central oligotrophic stations. The in situ copepod fecal pellet production varied between 1 and 1,000 mu g C m(-3) day(-1). At all stations, the retention of fecal pellets in the upper 400 m of the water column was more than 99% and the vertical export of fecal pellets was low (< 0.02 mg m(-2) day(-1)).
