Zusammenfassung.   Die intelligente Ressourcenadaption ist eine der gro?en Herausforderungen für die n?chste Generation mobiler Navigationssysteme. Da man typischerweise mehrere Fortbewegungsarten oder Verkehrsmittel kombinieren muss, um an einen Zielort zu gelangen, muss sichergestellt werden, dass mobile, allgegenw?rtige Navigationshilfen dies über eine jeweils situationsangepasste Benutzerschnittstelle unterstützen. Der notwendige Wechsel zwischen verschiedenen Positionierungstechnologien soll für den Endbenutzer m?glichst unbemerkt bleiben. Im folgenden wird ein hybrides Personennavigationssystem vorgestellt, das die in bestimmten Fortbewegungssituationen verfügbaren Positionierungstechnologien und deren Genauigkeit optimal nutzt, um die Pr?sentation der Wegbeschreibung auf verschiedene Endger?te und Ausgabemodalit?ten sowie die kognitive Ressourcenlage des Benutzers zu adaptieren.

Assessing the Utility of Item Response Models: Computerized Adaptive Testing     

G. Gage Kingsbury  Ronald L. Houser 《Educational Measurement》1993,12(1):21-27

How has Item Response Theory helped solve problems in the development and use of computer-adaptive tests? Do we need to balance item content with computer-adaptive tests? Could we use IRT to evaluate unusual responses to computer-delivered tests?  相似文献

Henry Holt a-spinning in his grave: Literary agenting yesterday and today     

Thomas L. Bonn 《Publishing Research Quarterly》1994,10(1):55-65

The role of the literary agent and the reception granted agents by publishers have changed markedly over the course of the twentieth century. Henry Holt’s views of agents, written in the first decade of the century, help define the status and activities of agents at that time. These are compared with the role of agents today, using archival sources, the book trade literature, and interviews. Thomas L. Bonn, review editor of this journal, is a librarian, Library at State University College at Cortland. He is the author ofUnder Cover: An Illustrated History of American Mass Market Paperbacks andHeavy Traffic and High Culture: The New American Library as Literary Gatekeeper. He is working on a study of American literary agents.  相似文献

Gardening as a cognitive activity     

Deborah G. Ventis 《Early Childhood Education Journal》1992,19(3):32-34

Gardening and children are a natural combination; children love to play in the dirt, and are fascinated by growing things. The benefits of having a garden can go beyond the fresh vegetables and flowers, a lot can be learned in the process. Although skills involved in planting and caring for the garden and acquiring a rudimentary knowledge of biology are obvious benefits, many other cognitive skills can be introduced or reinforced with a garden project.Deborah G. Ventis is Associate Professor of Psychology, College of William and Mary, Williamsburgh, VA.  相似文献
