Information tasks toward a user-centered approach to information systems
No full textIntroduction / Bryce Allen -- Information needs and information design / Bryce Allen -- Expressing information needs / Bryce Allen -- Designing systems to meet expressed information needs / Bryce Allen -- Information tasks : interacting with information systems / Bryce Allen -- Design details for information systems / Bryce Allen -- An introduction to user-centered information-system design / Bryce Allen -- Information services from the user's perspective / Bryce Allen -- Information institutions / Bryce Allen -- Conclusion : user-centered design and evaluation / Bryce Allen -- Information needs / Bryce AllenThe user-centered approach is central to the creation of usable information systems, services, and institutions. Information system design should derive from user research into information needs, tasks accomplished in meeting those needs, and resources used in the tasks. Information Tasks summarizes user research, then presents design sketches of systems that illustrate how design is linked to research. Also discussed are usable information services and an overview of the organization and economics of information institutions. This comprehensive user-centered approach provides an agenda for information research, design, and education that challenges many accepted beliefs and suggests new directions for information work. Information Tasks is of interest to library and information science students and faculty interested in information storage and retrieval, user studies, and systems analysis design. Students and scholars of human factors in systems design, human-computer interaction, and cognitive engineering also find the text useful. It reviews user research from many disciplines, and links research to practical design issues. It provides a unified model for user studies and user-centered design, and includes how-to summaries of design chapters. It shows how designers can investigate their user communities. It provides a general template for the design process. It integrates all aspects of information design, and discusses library issues in the larger information contex

Microlensing of circumstellar envelopes: II. emission lines from radial and azimuthal flow during fold caustic crossings
No full textThis paper examines the line profile evolution due to bulk motion in circumstellar envelopes during microlensing fold caustic crossing events. These events have recently been shown to be a sensitive probe of stellar surface brightness profiles, thus providing a means - through both photometric and spectroscopic observations - to constrain and test stellar atmosphere models. Here it is demonstrated, through the examination of simplified line profiles, that spectroscopic studies of fold caustic crossings could also prove to be a powerful diagnostic of bulk motion in circumstellar envelopes

No full textThe author, Ida Allen, recounts some of her life in Maine\u27s woods. She was born in a Moxie Gorge log camp in the 1910s, and she remembers how the river drivers and lumbermen got logs from Lake Moxie over Moxie Falls ( the Niagara of the north ) through Moosehead Lake to the company mills.
