Original Research By Young Twinkle Students (ORBYTS): Ephemeris Refinement of Transiting Exoplanets III

We report photometric follow-up observations of thirteen exoplanets (HATS-1 b, HATS-2 b, HATS-3 b, HAT-P-18 b, HAT-P-27 b, HAT-P-30 b, HAT-P-55 b, KELT-4A b, WASP-25 b, WASP-42 b, WASP-57 b, WASP-61 b and WASP-123 b), as part of the Original Research By Young Twinkle Students (ORBYTS) programme. All these planets are potentially viable targets for atmospheric characterisation and our data, which were taken using the LCOGT network of ground-based telescopes, will be combined with observations from other users of ExoClock to ensure that the transit times of these planets continue to be well-known, far into the future

The Relationship Between Ward Social Climate, Ward Sense of Community, and Incidents of Disruptive Behavior: A Study of a High Secure Psychiatric Sample

Assaults and seclusions within the UK impede patient recovery, and carry a combined UK cost of £126 million a year. Research has identified low ward social climate as a factor that contributes to such institutionalised disruptive behaviour. A related concept, sense of community, has been associated with disruptive behaviour in non-clinical communities, but has not been studied in forensic or psychiatric settings – and thus its contribution to disruptive behaviour in secure psychiatric care is unknown. The current study investigates the relationship between self-reported sense of community and social climate scores with incidents of disruptive behaviour (i.e. assaults and seclusions) within a UK high secure psychiatric hospital. Findings reveal that both social climate and sense of community predict incidents of disruptive behaviour, with hierarchical modelling suggesting that sense of community is the better predictor of disruptive behaviour. This study argues that sense of community should be monitored in high secure hospitals

Structure and Properties of Stoichiometric Complexes Formed by Sodium Poly(alpha,L-glutamate) and Oppositely Charged Surfactants

The conformational and structural properties of the stoichiometric complexes formed by poly(a.,L­glutamate) anions and alkyltrimethylammonium cations with chain lengths of twelve, sixteen, and eighteen carbon atoms were examined by circular dichroism, infrared, differential scanning calorimetry, and X-ray diffraction techniques. The polypeptide chains complexed with the surfactants adopt a.-helical conformations. The shorter surfactant alkyl chains, consisting of twelve and sixteen carbon atoms, are disordered in the complexes, while the longer surfactant chains of eighteen carbon atoms crystallize on a hexagonal lattice. All of the complexes are organized in lamellar structures consisting of alternating layers of poly(a.,L­glutamate) chains separated by bimolecular layers of the surfactants. The surfactant alkyl chains are interdigitated and perpendicular to the lamellar surfaces
