Within-group similarities and between-group differences are used to illustrate the socio-cultural nature of the concept-building process in highly collaborative computer science classrooms. Simultaneously, a social constructivist perspective is used to describe the individual aspects of this development. The study uses written explanations from…

This paper examines how future metadata capabilities could enable academic libraries to exploit information on the emerging Semantic Web in their library catalogues. Whereas current metadata architectures treat the Web as a simple means of interchanging bibliographic data that have been created by libraries, this paper suggests that academic…

The data defined in this article encompasses a range of topics, including data definitions, data management systems, infrastructure (both local and statewide), and the actual use of data to make decisions on either the administrative or instructional side. This emphasis on data has grown as technology has made the access and use of data easier.…

How has technology affected student achievement? There is a never-ending and misunderstood debate regarding technology integration that revolves around two main factors. First, the definition of student achievement has changed. Information technology literacy is now part of the skill set students will need to be successful, bringing with it a…

The authors investigated the role of syntax in verb learning in Mandarin Chinese, which allows pervasive ellipsis of noun arguments. Two questions were investigated using the Beijing corpus on CHILDES: (a) Does the input to young children manifest syntactic-semantic correspondences as needed for acquiring verb meanings? (b) Are verbs presented in…

We examined the use of residential services for people with intellectual disabilities in Finland from a regional perspective. Our aims were to investigate how service supply and need, as well as municipal factors, impact the use of residential services and to analyze whether the available information in registers and databases can be effectively…

Closer university-market relations are evidenced in increased university patenting, the formation of start-up companies, and partnerships with industry. They are part of a state and policy effort to link science and engineering to the market, thereby developing new technologies, stimulating economic growth, and creating new jobs. Yet the blurring…

The internal motivation to learn sets adult learners apart from children. Self-directed learning is associated with adult learners with the maturity to realize what they need to know and the internal motivation to learn it. This article provides sites to learn more about adult learning and resources to help support one's own informal,…

The concept of imminent suicide is examined. A search of National Electronic Library for Mental Health, the Cochrane Library, PubMed, OVID and MD Consult databases was conducted using the terms "suicide, imminent." The term "imminent" frequently appears in the mental health literature, finding common usage among clinicians. It is also a legal term…

This article reports new research supporting the two bipolar work task dimensions that underlie the World-of-Work Map (WWM) and Holland's hexagon--working with data versus ideas (D/I) and working with things versus people (T/P). Three databases provided diverse perspectives on basic work tasks: (a) general nature of work (expert ratings for 1,122…

Many employers in the United States have responded to the terrorist attacks of September 11, 2001, by initiating or expanding policies requiring background checks of prospective employees. Their ability to perform such checks has been abetted by the growth of computerized databases and of commercial enterprises that facilitate access to personal…

We discuss how relational databases constitute an ideal framework for representing and analyzing large-scale genomic data sets in biology. As a case study, we describe a Drosophila splice-site database that we recently developed at Wesleyan University for use in research and teaching. The database stores data about splice sites computed by a…

This article reports on an empirical study on novices' learning and retention with the Web-based interface to the Web of Science. The aim was to evaluate the performance of novice searchers in initially learning to use the search interface and in later use. Their performance in both sessions was measured in terms of time taken to perform tasks,…

Corporations employ data mining to analyze operations, find trends in recorded information, and look for new opportunities. Libraries are no different. Librarians manage large stores of data--about collections and usage, for example--and they also want to analyze this data to serve their users better. Analysts use data mining to query a data…
