Compares three recently introduced systems allowing multi‐user access to CD‐ROM via LANs. Discusses the test set‐up and the nature of the systems tested: OPTI‐NET, CD Net, and LANtastic. Surmises that all three systems achieve their objectives, the final choice being dependent on the buyer′s needs in terms of the system′s cost, user load, and present system environment constraint.

Recent initiatives in digital library research have suggested new models for the creation and organisation of digital information and its dissemination to virtual communities. PEN‐DOR (the Pennsylvania Education Network Digital Object Repository) is a digital library designed to provide access to the collective experience of teachers, students and administrators in public schools in building lesson plans and using curriculum materials. Using the WWW as a platform, PEN‐DOR incorporates current research in digital libraries to provide K‐12 educators with access to multimedia resources and tools to create new lesson plans and presentations, and to modify existing ones. Design problems addressed by the project include the design of a distributed, object‐oriented database architecture, the description and cataloguing of multimedia objects, and issues related to usability and training for a geographically scattered user community. Two critical aspects of the organisation of this digital library are the development of a method for the persistent identification of resources, and the design of a record structure based on recent developments in metadata. Resource identification has been achieved by adopting a system‐wide approach with an upgrade path to the emerging URN standards. In designing a record structure, the PEN‐DOR project has elected to use the GEM (Gateway to Educational Materials) metadata standard developed as part of the GEM union catalogue project. Content for the database is solicited from project partners, government agencies and educational resources Web sites, as well as from participating teachers. Once incorporated in the repository, materials can be organised in frameworks that form the basis for lessons, tutorials and presentations. As frameworks are developed, used, critiqueed and modified, they will form a community memory of past experience. Supported by the state’s Link‐to‐Learn programme, the system will function as a resource for educators throughout Pennsylvania.

This paper aims to investigate how organizational structure (i.e. centralized hierarchical vs decentralized egalitarian decision-making) can color leadership evaluations of equivalently positioned men and women independent of their actual leadership style. This study addresses three questions: Are men’s leadership abilities, in terms of competence, dominance and interpersonal skills, evaluated more positively than women when they lead a hierarchical company? Are men and women’s leadership abilities evaluated similarly when they lead an egalitarian company? Do organizational outcomes change these effects?

The research performs an eight-condition online vignette experiment on American community college students.

The findings suggest that organizational structure and outcomes influence how male versus female leaders are perceived. When leading a hierarchical company, male leaders not only gain more in perceived leadership ability when their company succeeds but are also less likely to lose legitimacy when their company fails. When leading successful egalitarian organizations, men and women’s leadership skills are thought to gain similar legitimacy, but when an egalitarian organization fails, perceptions of female leaders’ competence, status dominance and interpersonal skills drop more than those of men.

This study’s generalizablity is limited given the sample of participants and the context of the industry utilized in the vignette.

This study suggests that women’s promotion into leadership can be impeded by the decision-making structure of the organizations they lead independent of their individual choice in management style. Women leaders face not only disadvantaged evaluations of their leadership abilities in hierarchical organizations but are also not unilaterally advantaged in egalitarian organizations.

This paper highlights the need to theoretically examine how organizational structures fundamentally embed gender stereotypes.

Climate change is expected to cause larger and more frequent precipitation events in key agricultural regions of the United States, damaging crops and soils. Subsurface tile drainage is an important technology for mitigating the risks of a wetter climate in crop production. In this study, the authors examine how quickly farmers adapt to increased precipitation by investing in drainage technology.

Using farm-level data from the 2018 Agricultural Resource Management Survey (ARMS) of soybean producers, the authors construct a drainage adoption timeline based on when the operator began farming their land and when tile drainage was installed, if at all. The authors examine both the initial investment decision and the speed with which drainage is installed by adopters. A Heckman-style Poisson regression is used to model the count nature of adoption speed (measured in years taken to install tile drainage) and to correct for potential sample-selection bias.

The authors find that local precipitation is not a significant determinant of the drainage investment decision but may be highly influential in the timing of adoption among drainage users. Farms exposed to crop-damaging levels of precipitation install tile drainage faster than those with low to moderate levels of rainfall. Estimates of farm adaptation speeds are heterogeneous across farm and operator characteristics, most notably land tenure status.

Understanding how US farmers adapt to extreme weather through technology adoption is key to predicting the long-term impacts of climate change on America's food system. This study extends the existing climate adaptation literature by focusing on the speed of adoption of an important and increasingly common climate-mitigating technology – subsurface tile drainage.
