evaluating the investment that healthcare organisations make in quality improvement requires knowledge of impact at multiple levels, including patient care, workforce and other organisational resources. the degree to which these resources help organisations to survive and thrive in the challenging contexts in which healthcare is designed and delivered is unknown. investigating this question fro...

nowadays, with the advent of new satellite services, the need for resource management in the emerging fifth generation satellite systems (5g-satellite) is inevitable. thus, to solve this problem, the bandwidth manager for resource reservation in satellite link is mandatory. on the other hand, due to limited resources, their resource management­ is essential. in order to resource management in 5...

Makespan and cost minimization are two important factors in project investment. This paper considers a multi-mode resource-constrained project scheduling problem with the objective of minimizing costs, subject to a deadline constraint. A number of studies have focused on minimizing makespan or resource availability cost with a specified deadline. This problem assumes a fixed cost for the availa...

Bjorn Poonen discussed the “recognition problem” for finitely generated rings (and fields). That is, given two finitely generated commutative rings A and B, presented in terms of generators and relations, is there a decision procedure to determine whether or not these rings are isomorphic (this being, one would think, a basic issue for algebraic geometry!). Of course, if one drops the requireme...

There is a universal consensus that human resources represent the heart and soul of effective health systems everywhere. However, despite this consensus, human resource planning in low income countries remains a neglected, often poorly implemented and ineffective component of health-system development. The planning exercises that do take place are often inefficient, use inappropriate planning m...

In this paper we discuss laboratory experiments that address the problem of self-governance in an asymmetric commons dilemma. Small-scale irrigation systems that provide food for hundreds of millions of people around the world are probably the most common example of such dilemmas. Here, we formulate an abstract dilemma in which subjects make both a decision about investment in the provision of ...
