The aim of this work is to show how hypergraphs can be used as a systematic tool in the classi!cation of continuous boolean functions according to their degree of parallelism. Intuitively f is “less parallel” than g if it can be de!ned by a sequential program using g as its only free variable. It turns out that the poset induced by this preorder is (as for the degrees of recursion) a sup-semila...

In this paper several conceptual extensions to the theory of order-restricted free variable clausal tableaux which was initiated in 9, 8] are presented: atom orderings are replaced by the more general concept of a selection function, the substitutivity condition required for lifting is for certain variants of the calculus replaced by a much weaker assumption, and a rst version of order-restrict...

The equations that define the Lax pairs for generalized principal chiral models can be solved for any constant nondegenerate bilinear form on su(2). The solution is dependent on one free variable that can serve as the spectral parameter. Necessary conditions for the nonconstant metric on SU(2) that define the integrable models are given. 1991 MSC numbers: 35L10, 35L15, 34A55

Background. It cannot be denied that sport ecosystem consists of complex stakeholders. According to that, smart orchestration was needed to permit integration and promote active cross-sectoral. It required a suitable strategy to integrate and engage the entire system at any individual group, enterprise-level, and public sector. Therefore, the practical strategy will engage the entire system, so...

A participatory environmental management plan was prepared for Tuzla Lake, Turkey. Fuzzy cognitive mapping approach was used to obtain stakeholder views and desires. Cognitive maps were prepared with 44 stakeholders (villagers, local decisionmakers, government and non-government organization (NGO) officials). Graph theory indices, statistical methods and "What-if" simulations were used in the a...

BACKGROUND Despite an increased number of economic evaluations of tobacco control interventions, the uptake by stakeholders continues to be limited. Understanding the underlying mechanism in adopting such economic decision-support tools by stakeholders is therefore important. By applying the I-Change Model, this study aims to identify which factors determine potential uptake of an economic deci...

BACKGROUND Bundled payments, also known as episode-based payments, are intended to contain health care costs and promote quality. In 2011 a bundled payment pilot program for total hip replacement was implemented by an integrated health care delivery system in conjunction with a commercial health plan subsidiary. In July 2015 the Centers for Medicare & Medicaid Services (CMS) proposed the Compre...
