The study concludes that the personal interaction between participants and researchers is the most important feature of decision-making by patients/carers to join studies. Taking into account the perspectives of people affected by cancer during the early stages of research design may enhance recruitment and retention and can contribute to the development of research protocols and ethics.

This paper closely examines the performance analysis for unbuffered multipath multistage interconnection networks. A critical discussion of commonly used analysis is provided to identify a basic flaw in the model. A new analysis based on the grouping of alternate links is proposed as an alternative to rectify the error. The results based on the new analysis and extensive simulation are presented for three representative networks. The simulation study strongly supports the results of the new analysis.
