The paper provides an analysis of the voting method known as delegable proxy voting, or liquid democracy. The analysis first positions liquid democracy within the theory of binary aggregation. It then focuses on two issues of the system: the occurrence of delegation cycles; and the effect of delegations on individual rationality when voting on logically interdependent propositions. It finally p...

Assisted living (AL) is a relatively new form of long-term care that offers residents personal care services and more independence in a home-like environment. Introduced to the United States in the 1980s, AL is changing the conventional thinking about how to care for frail older adults. One important issue to explore is registered nurse (RN) delegation to unlicensed assistive personnel (UAP), p...

Task delegation presents one of the business process security leitmotifs. It defines a mechanism that bridges the gap between both workflow and access control systems. There are two important issues relating to delegation, namely allowing task delegation to complete, and having a secure delegation within a workflow. Delegation completion and authorisation enforcement are specified under specifi...

International courts (ICs) clearly fit the paradigm of delegation examined in this volume. States operating as a collective principal create ICs through a revocable delegation contract; appoint IC judges; and can write or rewrite the mandate and laws that ICs interpret. Principal-agent (PA) theory expects courts to be among the more independent “agents,” intentionally so. As Giandomenico Majone...

Sometimes it is useful to be able to separate between the management of a set of resources, and the access to the resources themselves. Current accounts of delegation do not allow such distinctions to be easily made, however. We introduce a new model for delegation to address this issue. The approach is based on the idea of controlling the possible shapes of delegation chains. We use constraint...

Delegation is an important tool for authorization in large distributed environments. However, current delegation mechanisms used in emerging Grids have problems to allow for flexible and secure delegation. This paper presents a framework to realize restricted delegation using a specific attribute certificate with trust value in grid environments. The framework employs attribute certificates to ...

In existing delegation models, delegation security entirely depends on delegators and security administrators, for delegation constraint in these models is only a prerequisite condition. This paper proposes an Attribute-Based Delegation Model (ABDM) with an extended delegation constraint consisting of both delegation attribute expression (DAE) and delegation prerequisite condition (CR). In ABDM...

BACKGROUND Research suggests that health professionals who have trained together have a better understanding of one another's scope of practice and are thus equipped for teamwork during their professional careers. Dental hygiene-therapists (DHTs) are mid-level providers that can deliver routine care working alongside dentists. This study examines patterns of delegation (selected tasks and patie...

Delegation is a powerful mechanism to provide flexible and dynamic access control decisions. Delegation is particularly useful in federated environments where multiple systems, with their own security autonomy, are connected under one common federation. Although many delegation schemes have been studied, current models do not seriously take into account the issue of delegation commitment of the...
