Coming Full Circle—From Endless Complexity to Simplicity and Back Again

Coming Full Circle: How Health Worker Motivation and Performance in Results-Based Financing Arrangements Hinges on Strong and Adaptive Health Systems

Background This paper presents findings from a study which sought to understand why health workers working under the results-based financing (RBF) arrangements in Zimbabwe reported being satisfied with the improvements in working conditions and compensation, but paradoxically reported lower motivation levels compared to those not working under RBF arrangements.   Methods...

Rural Ageing: Iran is on the Brink of a New Social Problem

The paper aims to examine the population ageing as a new phenomenon effecting rural areas in Iran. Population ageing is going up throughout the country especially in the rural areas by 6.8 percent. fertility decline, increase in the youth migration to cities, and coming back to rural areas after retiring are the major factors which involve in rural ageing. This may jeopardize the communities. f...

Chaos/Complexity Theory and Education

Sciences exist to demonstrate the fundamental order underlying nature. Chaos/complexity theory is a novel and amazing field of scientific inquiry. Notions of our everyday experiences are somehow in connection to the laws of nature through chaos/complexity theory’s concerns with the relationships between simplicity and complexity, between orderliness and randomness (Retrieved from http://www.inc...

Robust H2 Performance: Guaranteeing Margins for LQG Regulators

This paper shows that H 2 (LQG) performance speciications can be combined with struc-tured uncertainty in the system, yielding robustness analysis conditions of the same nature and computational complexity as the corresponding conditions for H 1 performance. These conditions are convex feasibility tests in terms of Linear Matrix Inequalities, and can be proven to be necessary and suucient under...
