Media Resource Center Management in Higher Education: New Organizations for the Times

Changes in the organization of learning resources including language/learninglabs have occurred over the years. Surveys within higher education over the last tenyears indicate less local autonomy and more centralized control, either withinindividual colleges or within central media or library facilities. It is not clear whetherlibrary involvement is advantageous in all institutions. Factors affecting successfulintegration include the age, size, and traditions of the university, training and skills ofstaff and director, support of the central administration, and a clear mission for theuse of learning resources.An earlier version of this paper was presented for IALL at the Annual Conventionof the Association for Educational Communications and Technology in 1984 in Dallas,Texas

Comparative Effects of Therapy With Captopril and Digoxin in Patients With Mild to Moderate Heart Failure

This multicenter, double-blind, placebo-controlled study compares the effects of captopril treatment with those of digoxin treatment during maintenance diuretic therapy in patients with mild to moderate heart failure. Compared with placebo, captopril therapy resulted in significantly improved exercise time (mean increase, 82 s vs 35 s) and improved New York Heart Association class (41% vs 22%), but digoxin therapy did not. Digoxin treatment increased ejection fraction (4.4% increase) compared with captopril therapy (1.8% increase) and placebo (0.9% increase). The number of ventricular premature beats decreased 45% in the captopril group and increased 4% in the digoxin group in patients with more than ten ventricular premature beats per hour. Treatment failures, increased requirements for diuretic therapy, and hospitalizations were significantly more frequent in patients receiving placebo compared with those receiving either active drug. Transitory hypotension occurred more frequently with administration of captopril. Captopril treatment is significantly more effective than placebo and is an alternative to digoxin therapy in patients with mild to moderate heart failure who are receiving diuretic maintenance therapy.(JAMA 1988;259:539-544
