Spatial variation in the incidence of nonaffective and affective psychotic disorders exists in rural areas. This suggests that the social environment contributes to psychosis risk across the rural-urban gradient.

Signal offset optimization recently has been shown to be feasible with vehicle trajectory data at low levels of market penetration. Offset optimization was performed on two corridors with that type of data. A proposed procedure called “virtual detection” was used to process 6 weeks of trajectory splines and create vehicle arrival profiles for two corridors, comprising 25 signalized intersections. After data were processed and filtered, penetration rates between 0.09% and 0.80% were observed, with variations by approach. Then those arrival profiles were compared statistically with those measured with physical detectors, and most approaches showed statistically significant goodness of fit at a 90% confidence level. Finally, the arrival profiles created with virtual detection were used to optimize offsets and compared with a solution derived from arrival profiles obtained with physical detectors. Results demonstrate that virtual detection can produce good-quality offsets with current market penetration rates of probe data. In addition, a sensitivity analysis of the sampling period indicated that 2 weeks may be sufficient for data collection at current penetration rates.

The first paper of this sequence discussed the division of childhood psychoses into those with onset before the age of 3 (infantile psychoses, I.P.) and those with onset after the age of 5 (late onset psychoses, L.O.P.). The second paper described in detail the clinical phenomena in 80 psychotic children so classified at Oxford or Newcastle (see Table I), and showed that this division corresponded to clear-cut distinctions in the clinical pictures. The I.P. group showed gaze avoidance, abnormal pre-occupations, self-isolating patterns of behaviour, echolalia, overactivity. The L.O.P. group showed hallucinations and thought disorder. With these two groups clearly established we now look to see whether anything in their family and background also distinguishes them.

Psychological research on sustainable consumption is developing a rich and diverse corpus of knowledge and tools, involving a broad range of disciplines. This very growth and diversity, however, poses challenges to our collective ability to build upon past research and progress in the field. We aim to place a selection of these challenges in the spotlight for discussion. In particular, we highlight some of the salient difficulties for early career researchers in psychology who are entering this field. Based on issues raised at a workshop conducted as part of the Psychology of Sustainable Consumption Small Group Meeting of the Society for the Psychological Study of Social Issues and the Society of Australasian Social Psychologists in 2018, we first examine challenges associated with working in transdisciplinary teams, measurement quality, data accessibility, and research dissemination. We then propose several options to address these, ranging from actions individual researchers can take, to more systemic changes.
