Testing for convergence among Mercosur countries [PDF]

The aim of this paper is to analyse the existence of price convergence in Mercosur. Two variables are considered, Consumer Price Indices to assess convergence in the goods and services markets and real interest rates, to analyse convergence in the money ...

Health expenditure trajectory and gastric cancer incidence in the National Health Insurance Senior Cohort: a nested case-control study

BMC Health Services Research
Background Gastric cancer is the fourth most common cancer and highly prevalent in South Korea. As one of the predictors of gastric cancer, we focused on health utilization patterns and expenditures, as the surrogate variables of health conditions.

Error analysis of QR algorithms for computing Lyapunov exponents [PDF]

, 2001
Lyapunov exponents give valuable information about long term dynamics. The discrete and continuous QR algorithms are widely used numerical techniques for computing approximate Lyapunov exponents, although they are not yet supported by a general error ...

A New Look at Economic Convergence in Europe: A Common Factor Approach [PDF]

We propose a common factor approach to analyse convergence, which we implement using principal components analysis. We show that this method provides a useful new way of approaching the convergence debate.

Temporal Evolution and Convergence Patterns of Urban Expansion in China: Evidence from 315 Cities over Two Decades

ISPRS International Journal of Geo-Information
Rapid urbanization in China has driven the continuous expansion of urban land over many years. While most studies have examined the scale, speed, and spatial distribution of urban expansion, few have explored its temporal evolution and convergence ...

Relationship Between Craniovertebral Angle and Upper Trapezius Muscle Stiffness and Tone in Office Workers

Physical Therapy Korea
Background: With the increase of seated work, interest in forward head posture (FHP) has grown. Prolonged computer tasks with FHP have been considered a factor that increases the stiffness and tone of the upper trapezius (UT) muscle.
