Experimental data has recently become available on the transverse 
target single-spin asymmetry (SSA) for inclusive DIS.  I will 
present analytical and numerical results for this observable, which 
also have implications for the current extractions of the Qiu-Sterman 
function T_F(x,x) that arises in transverse SSAs from pp collisions.  
Possible resolutions to the so-called "sign-mismatch" 
crisis including a new calculation of the fragmentation 
contribution to the transverse SSA in pp collisions 
will also be explored.  Moreover, extensive work has 
been done on the leading-twist (twist-2) double-longitudinal spin asymmetry 
A_LL.  Here I will focus on the analysis of the longitudinal-transverse 
spin asymmetry A_LT for photon, hadron, and jet production from pp 
collisions.  Furthermore, I will discuss how this observable could 
give insight into both the A_LL and transverse SSA domains.
