Non-reflexivity of the Banach space $\mathrm{\Lambda }B{V}^{(p)}$

In this paper, we show that the Waterman-Shiba space is non-reflexive. In fact, Prus-Wiśniowski and Ruckle, in \cite{1}, generalized the well-known fact that states the space of bounded variation functions is non-reflexive. Here, an improvement of that result is provided.
