title: Total site heat integration: Utility selection and optimisation using cost and exergy derivative analysis

authors: Tarighaleslami, Amir Hossein

subjects: Total site heat integration

abstract: This paper presents a new Total Site Heat Integration utility temperature selection and optimisation method that can optimise both non-isothermal (e.g. hot water) and isothermal (e.g. steam) utilities. None of the existing methods addresses both non-isothermal and isothermal utility selection and optimisation incorporated in a single procedure. The optimisation affects heat recovery, the number of heat exchangers in Total Site Heat Exchanger Network, heat transfer area, exergy destruction (ED), Utility Cost (UC), Annualised Capital Cost (CC), and Total Annualised Cost (TC). Three optimisation parameters, UC, ED, and TC have been incorporated into a derivative based optimisation procedure where derivatives are minimised sequentially and iteratively based on the specified approach. The new optimisation procedure has been carried out for three different approaches as the combinations of optimisation parameters based on the created derivative map. The merits of the new method have been illustrated using three case studies. These case studies represent a diverse range of processing types and temperatures. Results for the case studies suggest the best derivative optimisation approach is to first optimise UC in combination with ED and then optimise TC. For this approach, TC reductions between 0.6 to 4.6 % for different case studies and scenarios are achieved.

title: Ultra-Brief Clinical Outcome Evaluations in New Zealand: A New Zealand Perspective on the Outcome Rating Scale and Session Rating Scale

authors: Pay, Rebecca Ngaire

subjects: Outcome Evaluations

abstract: Outcome evaluations are becoming a routine aspect of psychotherapy, yet many measures are deemed inappropriate for everyday clinical use. Outcome evaluations help to inform clinical decision making and enhance treatment effects, whilst guiding therapy and tracking the client’s progress. Many current outcome evaluations are overly complex, lengthy and are not providing information in the most effective format possible. Given that mental health services nationally are increasingly being accessed, it is essential that the most effective and feasible outcome evaluations are being administered to maintain the meaningfulness of therapy. 

The present study explored an ultra-brief treatment session outcome measure called the Outcome Rating Scale (ORS), and compared it to the current New Zealand mandated outcome evaluation Health of Our Nation Outcome Scale (HoNOSCA) (N = 98). A quantitative, non-experimental correlational approach was taken, as studied in a clinical sample. Data was obtained through Lakes District Health Board, Infant, Child and Adolescent Mental Health Services.

The findings suggest that the ORS measures change and that it is comparable to HoNOSCA on 4 of the 13 HoNOSCA items. Interestingly, these 4 HoNOSCA items all significantly correlate with ORS’s ‘Overall’ measure. Higher ORS scores positively correlate with higher SRS scores, highlighting the importance of therapeutic alliance. Maori intake scores are slightly lower than European intake scores, but even out following therapy. Implications for future clinical directions and future research are discussed.
