Hemorrhage volume and ventricular extension are the best predictors of early deterioration and mortality in black Americans with SICH.

1978). Groups are usually defined a priori by some criterion external to the set of variables measured, e.g., rootstocks (Cruz-Castillo et al., 1992), carbohydrate status (Prins et al., 1990), supermarkets selling flowers (Behe et al., 1992), tree species (Majer et al., 1992), or swede (Brassica napus L., Napobrassica Group) cultivars (Cole and Phelps, 1979). The objective of this paper is to present a description of CDA and demonstrate its applicability and potential in horticultural research.

To date researchers have had difficulty establishing reliable conclusions in studies comparing traditional forms of learning (eg paper-based or classroom based) vs online learning in relation to student learning outcomes; no consistent results have emerged, and many studies have not been controlled for factors other than lesson mode. This paper compares the effects of presenting two versions of lessons on punctuation that differed only in their mode of presentation. 59 students completed a pre-lesson questionnaire, and after the lessons completed another questionnaire plus the NASA-TLX which tests subjective cognitive workload stress. The results showed that students who sat the lessons on paper performed 24% better than those who sat the lessons online. Reasons for this difference in learning outcomes are considered, but no clear reason is apparent in the data from this study. The study sounds a note of caution in terms of the move by tertiary institutions to online and/or blended learning, and suggests further studies are required which assess learning outcomes in different mode of learning.
