Wireless Handheld Computers in the Preclinical Undergraduate Curriculum

This report presents the results of a pilot project using wireless PDAs as teaching tools in an undergraduate medical curriculum. This technology was used to foster a transition from a passive to an interactive learning environment in the classroom and provided a solution for the implementation of computer-based exams for a large class. Wayne State Medical School recently provided model e570 Toshiba PocketPCs® (personal digital assistants or PDAs), network interface cards, and application software developed by CampusMobility® to 20 sophomore medical students. The pilot group of preclinical students used the PDAs to access web-based course content, for communication, scheduling, to participate in interactive teaching sessions, and to complete course evaluations. Another part of this pilot has been to utilize the PDAs for computer-based exams in a wireless environment. Server authentication that restricted access during the exams and a proctoring console to monitor and record the PDA screens will be described in this report. Results of a student satisfaction survey will be present

Reproductive ecology of Canada mayflower (Maianthemum canadense Desf)

Canada mayflower (Maianthemum canadense var. canadense Desf.), a rhizomatous perennial herb, was the subject of field experiments investigating the role of several factors on the sexual reproduction of ramets. Mayflower ramets may be either flowering (with 2-3 leaves and a terminal inflorescence consisting of 4-35 perfect flowers) or vegetative (1 leaf). Pollen addition increased the number of seeds matured by ramets in three out of four years in which pollen level was experimentally manipulated. The lack of compatible pollen is thought to be a major factor limiting seed maturation by ramets. The act of severing the rhizomes, such that ramets were isolated from the rest of the genet, also limited the number of seeds matured by ramets, but only when pollen was not limiting. In addition, rhizome severing was responsible for a reduction of, on average, 3.2 flowers brought to anthesis per ramet. Rhizome severing did not appear to delay flowering or to decrease the length of time that flowers were receptive to pollen. Rhizome severing also resulted in increased initiation of rhizomes, while the level of pollination (open pollinated, overpollinated, bagged, and vegetative) was independent of rhizome initiation. The number of seeds matured per ramet was negatively correlated with the mean weight of seeds, indicating that individual ramets were to some extent resource limited with few-seeded ramets maturing heavier seeds than ramets bearing many seeds. There was no difference detected in the mean number of seeds matured by overpollinated ramets flowering for the first and second time. The number of seeds matured per ramet was related to the identity of the ramet directly acropetal and basipetal on the same rhizome system ( context ). The most common context was also the one with the lowest seed maturation (no ramet or a dead ramet both acropetal and basipetal). Flowering ramets were older than vegetative ramets and differed in their contexts. Ages also differed with context and permitted a first attempt at inferring ramet and genet development

Up The Hudson Or On The Sound

[Verse] When it’s red hot in town and the sun’s beating down, And you long for a breath of fresh air There is only one way, And of that I can say The others with it can’t compare In the day or the night, Ev’ry thing is just right, If you go up the Hudson or Sound So take a straight tip Just go on a trip Where pleasure and comfort abound After [Chorus] Noons we go up the Hudson, In the evening we’re on the Sound In the steamer city of Worcester a floating palace is found With music soothing our senses, And a breeze blowing fresh and strong It is one joyful song, As we’re sailing along, Up the Hudson or on the Sound
