BACKGROUND With implementation of Chinese universal healthcare, the performance of urban and rural residents' healthcare and the degree of satisfaction with publicly financed health services have become a hot issue in assessing health reforms in China. An evaluation model of health services in community and evaluation indexes of health-system performance have been put forward in related researc...

The conditions for a Runge–Kutta method to be of order p with p≥5 scalar non-autonomous problem are proper subset the vector problem. Nevertheless, methods that were derived historically only problems happened same problems. We relate factorisations trees into “atomic stumps” and enumerate those up p=20. Using special search procedure over unsatisfied conditions, new “ambiguous orders” five six...

Background: The lower job satisfaction of health-care staff will lead to more brain drain, worse work performance, and poorer health-care outcomes. The aim of this study was to identify patterns of job satisfaction among health-care staff in rural China, and to investigate the association between the latent clusters and health-care staff's personal and professional features; Methods: We selecte...

This paper investigates experimentally the e ects of arousing content on viewing choices and satisfaction in television consumption. We test the hypothesis that the portrayal of arousing content combines high attraction and low satisfaction and is thus responsible for suboptimal choices. In our experiment, subjects can choose among three programs during a viewing session. In the experimental co...

In this paper, a bi-objective pharmaceutical supply chain network under uncertainty demand and transportation costs is modeled and developed. To control the uncertainty parameters, the robust optimization method is considering. The main objective of this paper determines the number and location of potential facilities such as drug manufacture centers and drug distribution centers by considering...

Collaborative filtering one of the recommendation techniques has been applied for e-learning recently. This technique makes an assumption that each user rates for an item once. However, in educational environment, each student may perform a task (problem) several times. Thus, applying original collaborative filtering for student's task recommendation may produce unsatisfied results. We propose ...

We study the behavior of ASAT, a heuristic for solving satisfiability problems by stochastic local search near the SAT/UNSAT transition. The heuristic is focused, i.e. only variables in unsatisfied clauses are updated in each step, and is significantly simpler, while similar to, walksat or Focused Metropolis Search. We show that ASAT solves instances as large as N = 10 in linear time, on averag...
