Governments are increasingly establishing health regions to deal with current challenges of public health service. These regions are seen as instruments to balance public and private stakeholders, and offer health care to regional citizens as well as to medical/health tourists. However, it is still unclear how the development of such health regions as well as their governance may be conceptualized. We apply Luhmann's system theory approach in ...

The financial supply chain is increasingly recognized as an area offering significant potential for generating bottom-line improvements and creating competitive advantage. Insurers’ appraisal is one of the basic decisions for a company, and the choosing course has always many criterions. Considering the stability of the financial supply chain, the coordination evaluation and fuzzy multi-objective evaluation model of insurers’ risk management are ...

Multivariate polynomial system solving and polynomial optimization problems arise as central problems in many systems theory, identification and control settings. Traditionally, methods for solving polynomial equations have been developed in the area of algebraic geometry. Although a large body of literature is available, it is known as one of the most inaccessible fields of mathematics. In this paper we present a method for solving systems of ...

© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. Multidimensional systems are becoming increasingly important as they provide a promising tool for estimation, simulation and control, while going beyond the traditional setting of one-dimensional systems. The analysis of multidimensional systems is linked to multivariate polynomials, and is therefore more difficult than the well-known analysis of one-dimensional systems, ...

Anatomical damage to pelvic floor structures may cause multiple symptoms. The Integral Theory System Questionnaire (ITSQ) is a holistic questionnaire that uses symptoms to help locate damage in specific connective tissue structures as a guide to reconstructive surgery. It is based on the integral theory, which states that pelvic floor symptoms and prolapse are both caused by lax suspensory ligaments. The aim of the present study was to ...

We consider the problem of computing (approximate) greatest common divisors for matrix polynomials and we present some related facts and applications in system and control theory. The main application is to compute the distance of a controllable multi-input multi-output system to the set of uncontrollable ones; then we describe some related results.

We reformulate the equation characterising the critical points of the hypersymplectic action functional as solutions of a Hamiltonian system on the iterated loop space. The intend is to gain more insight into dynamics of hyperkahler Floer theory.

The standard model of political party system density combines two traditions to explain why some countries have more political parties than others, one tradition that emphasizes social cleavages and another that emphasizes electoral institutions, especially district magnitude. Despite its considerable success, there are several reasons to be less than fully satisfied with the standard model. We examine two of these problems associated with the ...
