AIM: This study aimed to determine the prevalence of high-risk sexual behaviours, sequelae and associated factors in young people attending a youth mental health service. METHODS: The study design was a cross-sectional survey of 103 young people aged between 15-25 years carried out across four specialist mental health clinics. A questionnaire on the sexual health of secondary level students was adapted for this study. Mental health symptomatology was assessed through the Brief Psychiatric Rating Scale (BPRS). RESULTS: The mean age was 20.9 (SD ±2.8) years, with 50.5% being female, 41.7% male and 7.7% transgender. A total of 52.4% (N = 54) attended the psychosis [EPPIC] clinic; 15.6% (N = 16) attended the ultra-high risk for psychosis [PACE] clinic; 19.4% (N = 20) attended the personality disorders [HYPE] clinic; and 12.6% (N = 13) attended the mood clinic [YMC]. The mean BPRS score was 47.7 (SD ±12.2). A total of 77.7% of young people had previously been sexually active and of these, 37.5% did not use consistent contraception; 26.3% had been pregnant, of which 95.2% were unplanned. A total of 68.8% reported having been tested for sexually transmitted infections and 25.5% tested positive. The severity of symptoms or clinical characteristics were not associated with engagement in high-risk sexual behaviours. CONCLUSIONS: These results indicate that young people with mental health disorders have high needs in regard to their sexual health, which could be addressed by incorporating sexual health referral pathways into early intervention services.

Photodissociation cross sections for the SH$^+$ radical are computed from all rovibrational (RV) levels of the ground electronic state X$~^3\Sigma^-$ for wavelengths from threshold to 500~\AA. The five electronic transitions, $2~ ^3\Sigma^- \leftarrow$ X$~^3\Sigma^-$, $3~ ^3\Sigma^- \leftarrow$ X$~^3\Sigma^-$, $A~ ^3\Pi \leftarrow$ X$~^3\Sigma^-$, $2~ ^3\Pi \leftarrow$ X$~^3\Sigma^-$, and $3~ ^3\Pi \leftarrow$ X$~^3\Sigma^-$, are treated with a fully quantum-mechanical two-state model, {i.e. no non-adiabatic coupling between excited states was included in our work.}. The photodissociation calculations incorporate adiabatic potentials and transition dipole moment functions computed in the multireference configuration interaction approach along with the Davidson correction (MRCI+Q), but adjusted to match available experimental molecular data and asymptotic atomic limits. Local thermodynamic equilibrium (LTE) photodissociation cross sections were computed which assume a Boltzmann distribution of RV levels in the X$~^3\Sigma^-$ molecular state of the SH$^+$ cation. The LTE cross sections are presented for temperatures in the range 1000-10,000~K. Applications of the current photodissociation cross sections to interstellar gas, photon-dominated regions, and stellar atmospheres are briefly discussed., Comment: 21 pages, 13 figures, 2 tables. Accepted in J Phys. B: At. Mol. Opt. Phys. for the special issue on Atomic and molecular data for astrophysics

This report presents the results of a quantitative investigation into the optimum selection of screening and debugging methods for the purpose of removing defects, and hence improving reliability, throughout the development process. A computerized optimization model has been developed which can be used to address three problem areas; (1) Select an optimum sequence of screens for a fixed dollar expenditure, (2) Select a sequence of screens which minimizes costs in the face of a fixed desired reliability improvement, and (3) Provide quantitative for performing screening/debugging tradeoffs. In order to implement the model it was necessary to obtain data to compute test strengths and test costs. The model includes four assembly levels, five types of screens (temperature cycling constant temperature, vibration constant power and power cycling), provides for introduction of defects at each assembly level and includes the rework cycle.
