Abstract: We provide a Laakso construction to prove that the property of having an equivalent norm with the property $ (\beta )$ of Rolewicz is qualitatively preserved via surjective uniform quotient mappings between separable Banach spaces. On the other hand, we show that the $ (\beta )$-modulus is not quantitatively preserved via such a map by exhibiting two uniformly homeomorphic Banach spaces that do not have $ (\beta )$-moduli of the same power type even under renorming.
