Role Ambiguity Exists when an individual has inadequate information about his or her roles or duties.

If line managers become mentors, this can also reduce the clarity of roles. In fact, most mentoring schemes that tried this approach to providing mentors had to pull back because the line boss was imable to cope with the ambiguity of roles. Being an objective coididante on the one hand and having to appraise the employee on the other proves too difficult to reconcile. 

It will be suggested that the role of the symbolic level in mediating discussion of the macroscopic and sub-microscopic levels not only offers another layer of complexity for learners, but through its ambiguity (where symbols may often represent either macroscopic or sub-microscopic levels) offers scope for the novice learner to confuse discussion of the macroscopic and sub-microscopic levels. 

However, others reached more ambiguous conclusions. Gates et al. developed a 2D model based on coupling NO vibration to surface phonons, but ignoring the possible role of electron-hole pairs, and successfully captured... 

Furthermore, the role of a poly hydroxy alcohol, like ethylene glycol, seems ambiguous. As mentioned above, it is believed that the presence of ethylene glycol favours esterification of chelates. IR and NMR studies performed in [7] do not present solid proofs of such a belief. Synthetic routines with and without alcohols look the same, and the absence of alcohol seem not to influence the properties of precursors and final products. Some evidence exists enabling one to consider the esterification idea liable to more than one interpretation it has been reported in [4] that the presence of ethylene glycol does not influence the morphology of oxides. 

The role of the solvent in polymer adsorption has been the subject of much discussion. For example, theories have made predictions about the effect of the polymer/solvent interaction (i.e. Flory Huggins x parameter) on adsorption. For many systems, x parameters had already been tabulated so that a number of adsorption studies focused attention on this parameter. In spite of much effort, available data are ambiguous, sometimes verifying and sometimes contradicting the trends predicted by theory.
