Agricultural extension in Vietnam is in transition as the economy moves to a market orientation. The national extension service created in 1993 is constrained by lack of funding, staff, and access to current extension knowledge. (SK)

CITINET is a network of learning centers in Sheffield, England, where adults can access information about educational opportunities and use information and communications technology. Both job-related learning and nonvocational learning are supported. (SK)

Provides a framework for discussing public computer systems (PCS) as tools in client-organization communication. Describes a three-level analysis scheme (object, functional, strategic) for client-organization encounters. Concludes that PCSs provide an important new focus for information-systems studies because they can be used to design new social…

Reviews the use of handheld computers and mobile imaging devices for teaching and learning. Highlights include features of handheld computers to consider for use in elementary and secondary education; graphic calculators as part of local area networks; digital cameras; and portable scanners. (LRW)

Interviewed lesbian, gay, and heterosexual youth regarding their friendship patterns. Homosexual youth lived farther from their friends than heterosexual youth. Gay males and heterosexual females talked more often on the telephone with friends. Gay males were least likely to have friends of the same sex and same sexual orientation. Lesbians were…

Introduces the notion of a class networked with graphing calculators and discusses the pedagogical implications of this set up. New teaching methods are necessary to exploit the potential of the system. (MM)

This paper reports the findings from an observational study of a digital video library system, DiVA, involving deaf students and students with other medical conditions affecting their use of video material. The Digital Video Applications (DiVA) system supports searching for and playing educational videos, and displays transcripts of the audio…

Recent research on the social support networks of homeless and runaway youth suggest the social networks of runaway youth are made up largely of transient deviant peer relationships. This paper examined social network characteristics of 428 homeless and runaway adolescents from small-to moderate-sized cities in four Midwestern states. We…

Internet Protocol (IP) Telephony, or voice-over IP (VoIP), has proved to be a wise decision for many organizations. This technology crosses the boundaries of public and private networks, enterprise and residential markets, voice and data technologies, as well as local and long-distance services. The convergence of voice and data into a single,…

The goal of this article is to advance an ecological theory of knowing, one that prioritizes engaged participation over knowledge acquisition. To this end, the authors begin by describing the environment in terms of "affordance networks": functionally bound potentials extended in time that can be acted upon to realize particular goals. Although…

It is well understood that one learns much of what one knows through one's network of relationships and through shared discussion and activity. A logical extension of this idea is the growing prominence in the UK where formal school-to-school networking such as Education Action Zones and Excellence in Cities has been established. This article…

Small libraries in small towns often have a very low level of technical skill on staff. Furthermore, obtaining skilled technical support can frequently be pretty expensive. Even when one is available, a clever…

An effective systems librarian must understand security vulnerabilities and be proactive in preventing problems. Specifics of future attacks or security challenges cannot possibly be anticipated, but this paper suggests some simple measures that can be taken to make attacks less likely to occur: program the operating system to get automatic…

The study of measurement models in psychometrics by means of dimensionality reduction techniques such as Principal Components Analysis (PCA) is a very common practice. In recent times, an upsurge of interest in the study of artificial neural networks apt to computing a principal component extraction has been observed. Despite this interest, the…
