According to the Hugenholtz-Van Hove theorem, nuclear symmetry energy \esymand its slope \lr at an arbitrary density $\rho$ are determined by the nucleonisovector (symmetry) potential \usym and its momentum dependence$\frac{\partial U_{sym}}{\partial k}$. The latter determines uniquely theneutron-proton effective k-mass splitting $m^*_{n-p}(\rho,\delta)\equiv (m_{\rmn}^*-m_{\rm p}^*)/m$ in neutron-rich nucleonic matter of isospin asymmetry$\delta$. Using currently available constraints on the \es0 and \l0 at normaldensity $\rho_0$ of nuclear matter from 28 recent analyses of variousterrestrial nuclear laboratory experiments and astrophysical observations, wetry to infer the corresponding neutron-proton effective k-mass splitting$m^*_{n-p}(\rho_0,\delta)$. While the mean values of the$m^*_{n-p}(\rho_0,\delta)$ obtained from most of the studies are remarkablyconsistent with each other and scatter very closely around an empirical valueof \emass$=0.27\cdot\delta$, it is currently not possible to scientificallystate surely that the \emass is positive within the present knowledge of theuncertainties. Quantifying, better understanding and then further reducing theuncertainties using modern statistical and computational techniques inextracting the \es0 and \l0 from analyzing the experimental data are muchneeded.
