Purpose – The purpose of this research is to introduce a class of FRC (fuzzy random coefficient) volatility models and to study their moment properties. Fuzzy option values and the superiority of fuzzy forecasts over minimum mean‐square forecasts are also discussed in some detail....

Common methods of controlling river pollution include establishing water pollution monitoring stations located along the length of the river. The point where each station is located (sampling point) is of crucial importance and, obviously, depends on the reasons for the sample. Collecting data...

Purpose – The paper seeks to develop an analytical theory of project investment. Design/methodology/approach – The authors derive a partial differential equation that the variable cost of a project should satisfy, determine a proper initial condition through a thought experiment, and solve...

Haemoglobinopathies are a group of genetic disorders which are particularly prevalent among certain risk groups such as ethnic groups. Antenatal screening of potential haemoglobinopathy carriers allows early diagnosis for affected fetuses, leading to therapeutic intervention or termination....

Purpose – To validate a measure of use innovativeness, or how existing products are used in a novel and innovative manner. The measure has practical significance for innovation research as it consists of only nine items as opposed to the original 44. The use innovativeness measure derived from...
