All four major military services sponsor Junior Reserve Officers' Training Corps programs in high schools. The programs emphasize a mixture of classroom instruction and extracurricular activities ...such as drill and rifle teams. The rising tide of patriotism among high school students is discussed.
Mitochondrial DNA (MtDNA) with a neutral buoyant density of 1.681 g/ cm3 has been isolated from unfertilized eggs of Drosophila melanogaster. This DNA is a circular molecule with an average length of ...5.3 μm; it reassociates with a low C0t1/2 after denaturation, and in alkaline isopycnic centrifugation it separates into strands differing in density by 0.005 g/ cm3. MtDNA isolated from purified mitochondria of unfertilized eggs or from total larval DNA melts with three distinct thermal transitions. The three melting temperature values suggest that the molecule may have three regions differing in average base composition. DNA isolated from unfertilized eggs of D. melanogaster contains approximately equal amounts of MtDNA and another DNA with a buoyant density of 1.697 g/ cm3, slightly less dense than main peak DNA. The possibility that the heavier DNA fraction consists of amplified ribosomal DNA was excluded by hybridization experiments, but otherwise nothing is known of its origin or function.
A review of federal data points out a major challenge to closing the achievement gap between rich and poor students: the lack of fully qualified teachers in schools serving high numbers of low-income ...children.
The Faculty Summer Preceptor Program was instituted in the summer of 1987 to assist with the orientation of more than 200 newly employed graduate nurses at Thomas Jefferson University Hospital in ...Philadelphia. Plans had to be made to assist the staff in assimilating this large number of orientees without disrupting patient care delivery. Preceptorships were used extensively in nursing services during the past 10 years. A major advantage of using faculty is that they are very familiar with new graduates' skills, anxieties, and needs, and the faculty role closely corresponds with the role of the preceptor. The faculty is a "ready made" resource for nursing staff orientation.
