Mutualism has its limits: consequences of asymmetric interactions between a well-defended plant and its herbivorous pollinator.

Concern for pollinator health often focuses on social bees and their agricultural importance at the expense of other pollinators and their ecosystem services. When pollinating herbivores use the same plants as nectar sources and larval hosts, ecological conflicts emerge for both parties, as the pollinator's services are mitigated by herbivory and its larvae are harmed by plant defences. We tracked individual-level metrics of pollinator health-growth, survivorship, fecundity-across the life cycle of a pollinating herbivore, the common hawkmoth, , interacting with a rare plant, , that is polymorphic for the common floral volatile ()-(-)-linalool.

A Quick Measure of Theory of Mind in Autistic Adults: Decision Accuracy, Latency and Self-Awareness.

Autistic adults often experience difficulties in taking the perspective of others, potentially undermining their social interactions. We evaluated a quick, forced-choice version of the Adult Theory of Mind (A-ToM) test, which was designed to assess such difficulties and comprehensively evaluated by Brewer et al. (2017).

Measuring Theory of Mind in Adults with Autism Spectrum Disorder.

Deficits in Theory of Mind (ToM)-the ability to interpret others' beliefs, intentions and emotions-undermine the ability of individuals with Autism Spectrum Disorder (ASD) to interact in socially normative ways. This study provides psychometric data for the Adult-Theory of Mind (A-ToM) measure using video-scenarios based in part on Happé's (Instructions for theory of mind story task, 1999) Strange Stories test. The final items discriminated IQ-matched adults with ASD from controls on the social but not the physical items.

Pancreaticoduodenectomy for nonampullary duodenal lesions: indications and results.

Background: Pancreaticoduodenectomy (PD) is a complex procedure, associated with a definite risk of mortality and 30-50% risk of complications. For nonampullary duodenal lesions, PD can carry a higher morbidity as they are more commonly associated with a soft pancreas and narrow-calibre main pancreatic ducts. It is therefore paramount that the risks and benefits of surgery are considered carefully in this group of patients.

Low-flow active and passive sampling of VOCs using thermal desorption tubes: theory and application at an offset printing facility.

While air sampling techniques using adsorbent-based collection, thermal desorption and chromatographic analysis have found a niche in ambient air sampling, occupational applications have been more limited. This paper evaluates the use of thermal desorption techniques for low flow active and passive sampling configurations which allow conveniently long duration sampling in occupational settings and other high concentration environments. The use of an orifice enables flows as low as 0.
