What surprised you? A questionnaire to map unexpectedness through FBS variables
The paper presents the analysis of an original online survey that aims at checking the factors triggering surprise in randomly chosen evaluators who were submitted a set of surprising products. The authors use the answers to check the capability of a situated FBS-based model to help catch the main factors triggering surprise in products, here seen as a mismatch between what is interpreted and previously conceived expectations. The survey questionnaire shows to be effective in grabbing surprising factors and the results demonstrate that the model allows a strong ex-post convergence in the investigation of surprising factors

Systematizing new value proposition through a TRIZ-based classification of functional features
AbstractIn recent years, several TRIZ practitioners have focused their attention on the application of TRIZ concepts for new business strategy definition. Among the others, the Blue Ocean Strategy has attracted the largest consensus. Nevertheless, this methodological approach proves to be very elegant to describe past business innovation successes, while it provides just general directions if a new profile of “values” is requested for a given product or service. The present paper analyzes with a TRIZ perspective 32 case studies from the BOS literature and shows that more prescriptive guidelines can be identified from these experiences
Biochemical characterization of the POM-1 metallo-β-lactamase from Pseudomonas otitidis
The POM-1 metallo--lactamase is a subclass B3 resident enzyme produced by Pseudomonas otitidis, a pathogen causing otic infections. The enzyme was overproduced in Escherichia coli BL21(DE3), purified by chromatography, and subjected to structural and functional analysis. The purified POM-1 is a tetrameric enzyme of broad substrate specificity with higher catalytic activities with penicillins and carbapenems than with cephalosporins
