0240.3 Assessment
Research Question (Clear, unambiguous) "How are single mom’s career path constrained by family responsibility in Taiwan?"  This is a worthwhile question, but one difficult to pursue in this general way.
Relevant Literature The literature on the "motherhood penalty" is relevant, but the work on single mothers might be more important.
Causal Interpretations (clear, all parts defined, mechanisms, controls, plausible) While discrimination against single mothers may be significant in Taiwan, the research design issue that stands out is finding a way to distinguish that possibility from others.  In particular, being a single mother is not a random event, so we have to control for the conditions likely to produce single motherhood which could also affect future employment.  Also, we have to take into account the effects of motherhood, which both constrain single women's time and can influence their choices.
Data (variables, sample, comparison) I'm not familiar with Taiwanese data, but the referenced study does not sound as if it has the needed data.
Research Value Omitted from project outline.  However, the proposed project seems likely to be valuable, if the research goals can be met.
Overall A reasonable direction for research, but the research plan seems weakly developed so far.
