This study examines how knowledge and interest affect recall of information from a hypertext environment. Participants were 34 undergraduates enrolled at a college of education in a large western university. Results indicate that domain knowledge significantly predicted both structured and unstructured reading recall of a hypertext. In contrast to patterns found within research on traditional reading environments, interest did not significantly affect recall of hypertext information. Differential navigation patterns emerged in conjunction with varying levels of knowledge and may help to explain these results. The results are discussed in terms of current schema theoretic models of reading comprehension.

The IS 2010: Curriculum Guidelines for Undergraduate Degree Programs in Information Systems were published as a model to help academic IS programs establish a consistent curriculum that meets the needs of a global information economy. However, to-date, no study has examined the degree to which the IS 2010 model curriculum is being adopted and utilized in contemporary IS curricula. The purpose of this study is to evaluate the level of program adoption of the IS 2010 curriculum guidelines. Curriculum data were collected from 127 AACSB-accredited undergraduate information systems programs across the United States via a direct survey and interviews with department heads and undergraduate program directors. These data were then compared with the IS 2010 recommendations. Results indicate that: (1) IS programs exhibit a wide range of adherence to the IS 2010 core curriculum guidelines; (2) perceived adherence to IS 2010 guidelines among program administrators is higher than calculated adherence; (3) several non-IS 2010 core topics are still included as required components in many IS programs; (4) although few IS programs have formally implemented IS 2010 career tracks, perceptions of career tracks are generally favorable; (5) resource constraints and program enrollments/class sizes are commonly described barriers to developing career tracks.

(28.V11.86) EtAIC1,-promoted additions of organocopper reagents to camphor-derived, conjugated N-enoyl-sultams gave saturated and olefinic P-silylcarboxyl derivatives with high diastereodifferentiation. Nondestructive removal of the chiral auxiliary followed by oxidative Si-C bond cleavage furnished enantiomerically pure acetate-derived aldols and propionate-derived 'unfi'-aldols (oirr silyl-directed a methylation).P-Silylcarbonyl compounds show significant promise in organic synthesis. Two features of the P-SiPhMe, substituent are particularly interesting: 1 j its topological bias on a-enolate protonation and methylation [l] as well as 2) its convertibility into a OH group with retention of configuration [2].In continuation of previous work on asymmetric and hydride additions [4] to conjugated N-acyl-sultams, we report here the first asymmetric synthesis of p-silylcarboxylates and their transformation into enantiomerically pure acetate-derived aldols and propionate-derived 'anti'-aldols. Furthermore, we describe the analogous -face-selective preparation of y,6-alkenyl-,8-silylcarboxyl derivatives which offer additional synthetic possibilities via SET -type allylsilane substitutions2).For reasons of versatility, it was advantageous to incorporate the silyl group into the prochiral substrate.

For an alternative approach to racemic and to enantiomcrically pure ~,fi-alkenyl-B-silylcarbonyl derivatives by Cluisen rearrangements see [ S ] ; for asymmetric syntheses of non-functionalized allylsilanes, see [6]; for revicws on stercospecific SE2'-type substitutions of allylsilanes, see [7]. All new compounds were characterized by IR, 'H-NMR (360 MHL), and mass spectra. This acid (m.p. 89-91") was prepared in analogy to 3-(trimethylsilyl)acrylic acid [8] by successive treatment of ( E l -1,2-bis(tributylstannyl)ethylene [9] at -78" with BuLi, CISiPhMc,, BuLi, and CO,.
