The notion of a computation graph is introduced. A computation graph is a rooted, directed graph whose nodes are labelled by statements (instructions) to be executed. The motivation for developing computation graphs comes from a desire to represent programs by well‐defined, manipulable structures and to permit search (especially backtracking) to be a natural part of the execution of such programs. This initial work considers very simple computation graphs where the only statements that can be executed are assignment statements and tests. Procedure calls, parameter passing, etc. are not considered. The execution rule for computation graphs is based upon search procedures. The computation rule presented permits a computation graph to be executed depth first, breadth first or using a combination of both. This is done by defining functions, which are arguments to the computation rule, to control the traversal of the graph. The use of the rule is illustrated by describing functions to permit the rule to execute the same graph depth first and breadth first.

Recent developments in workstations and software that make it possible to extend the utility of existing library systems are discussed. These developments provide an excellent foundation on which to base future library automation, especially in the context of a research library. Further, this technology suggests that the concept of a “scholar's workstation” is technically feasible. Some experiences with the use of this technology to explore ideas central to the development of a scholar's workstation are also reported.

The aim of the chapter is to examine whether the challenges to administering the EU outlined by Les Metcalfe in his famous article, ‘After 1992, can the Commission manage Europe?’ have now been met. Metcalfe not only identified a ‘management deficit’ in the implementation of the single market programme arising from an oversight among policy makers, but highlighted a neglect of the administrative dimension of European integration among scholars.

The chapter draws on primary and secondary literature to track developments in respect of the three elements identified by Metcalfe: the small size of the European Commission, its poor internal coordination and weak leadership; the responsiveness of administrative bodies in the member states to the need for inter-organizational coordination; and the network-building and management capacity of the Commission.

Despite changes, such as further enlargement, agencification at national and EU levels, and the expansion of EU competencies that have exacerbated the management challenge confronting the EU, there have been significant developments that have closed the deficit. First, the Commission has become far better integrated, coordination upgraded, and leadership strengthened. Second, through networking, cooptation and other strategies the Commission has sought to assure the effective implementation and enforcement of the single market rules. Third, member state governments, ministries and agencies have sought to cultivate networked relations that have increased the manageability of EU administration.

To the knowledge of this author, this is the first attempt to revisit Metcalfe’s diagnosis and to review the extent to which the management deficit he identified has been addressed subsequently.

The chapter has implications for how inter-organizational coordination within the EU administrative system could be improved.

The chapter bears on the administrative capacity of the EU to deliver the policies decided by EU policy makers.

As well as offering an assessment of the extent to which progress has been made in addressing the management deficit identified by Les Metcalfe in his classic article, this chapter conceptualizes the EU administration as an entity that encompasses both EU institutions and administrative bodies in the member states. It advances the concept of the EU as a multi-level administration.

This study compared different types of full-time caregiver (e.g., children, older adults, COVID-19 patients) and subgroups (e.g., disability, race/ethnicity, sexual orientation) in the United States during the COVID-19 pandemic for potentially meaningful distinctions.

Data from the 9,854 full-time caregivers identified in Phase 3.2 (July 21–October 11, 2021) of the US Census Household Pulse Survey (HPS) were analyzed in this study using multinomial logistic regression to examine relationships between caregiver types, marginalized subgroups, generation, and vaccination status.

The prevalence of caregiving was low, but the type of full-time caregiving performed varied by demographic group (i.e., disability, race/ethnicity, sexual orientation, gender, generation, and vaccination status). The relative risk of being a COVID-19 caregiver remained significant for being a member of each of the marginalized groups examined after all adjustments.

To date, the HPS has not been analyzed to predict the type of full-time informal caregiving performed during the COVID-19 pandemic or their characteristics. Research limitations of this analysis include the cross-sectional, experimental dataset employed, as well as some variable measurement issues.

Prior informal caregiver research has often focused on the experiences of those caring for older adults or children with special healthcare needs. It may be instructive to learn whether and how informal caregivers excluded from paid employment during infectious disease outbreaks vary in meaningful ways from those engaged in other full-time caregiving. Because COVID-19 magnified equity concerns, examining demographic differences may also facilitate customization of pathways to post-caregiving workforce integration.

The first videodisc was demonstrated in 1927. A brief history of the videodisc is presented, describing the three major current manifestations of this storage medium—read‐only, write‐once, and erasable. Read‐only became an important information delivery format in 1985. During 1986, write‐once will begin to have impact on libraries and information centers. The current status of this technology, the major corporations involved in the field, and the potential uses for various types of storage media are described. A sidebar discusses Geac's use of optical media.

The chapter furnishes empirical evidence about the extent and profiles of autonomy of EU agencies, the modalities whereby they are steered and controlled, and the interactions they have in EU policy networks. It thus provides the bases for a more complete picture of the EU multi-level administration.

The research is a survey-based design. A questionnaire was administered between July 2009 and April 2010 to 30 EU agencies included in the study population. The questionnaire was sent to the executive director of all the agencies included in the study. Questions were closed-ended, either in the form of multiple choices – with one answer or with check-all-that-apply and an option for ‘other’ to be filled – or in scale format. The resulting data set included ratio, interval, ordinal, and nominal scales. The reference model employed for the investigation relies on the analytical model developed within the framework of the research project COST Action IS0651 CRIPO (Comparative Research into Current Trends in Public Sector Organization – see also ‘Acknowledgements’) for the study of public agencies in Europe (Verhoest, Van Thiel, Bouckaert, & Lægreid, 2012).

EU agencies display a rather low level of managerial, especially financial, autonomy; conversely, they enjoy relatively high policy autonomy. As to the way in which multiple ‘parent’ administration steer EU agencies, it emerges a composite picture, in which the crossroads of steering and control by the parent administrations and accountability by the agency lies in the executive director. In terms of interactions within policy networks, EU agencies interact in a significant way with the European Commission, with national-level agencies in the pertinent policy field, and with specific technical bodies where they are part of the configuration of the policy sector, whilst interactions with national ministries as well as with other EU agencies are rare. No single model can capture in full the overall features of EU agencies, although the ‘community level institution’ model seems to capture a number of the profiles of these agencies.

Both the literature on EU multi-level administration and research agendas in public management can benefit from inclusion of – and in-depth empirical knowledge about – EU agencies. The chapter provides important empirical evidence to these purposes.

EU agencies are actors in European public policy-making, albeit to a varied extent depending on the sector. The extent of autonomy and the way in which they are held to account are crucial aspects for an enhanced understanding of their influence on European public policy-making, as is their location in European policy networks.

Research presented in this chapter is the first systematic empirical investigation of EU agencies encompassing networking, steering and control and autonomy of EU agencies, based on primary data.

The long‐term goal for integrated information management at the Johns Hopkins Medical Institutions is the creation of a knowledge management environment—a network of databases that an individual would tap as one would one's own memory. An important library component in this emerging environment is WELMED, a general purpose bibliographic database management system that permits the library to distribute its databases and related services to its users through common, customizable interfaces. The characteristics and components of the WELMED system are detailed.
