Age estimation of wild boar (Sus scrofa) based on molariform mandibular tooth development and its application to seasonality at the Mesolithic site of Ringkloster

The molariform mandibular tooth development in wild boar has been described in order to increase the reliability and precision in age estimation. The age at eight different stages of tooth development has been determined based on radiographs of 114 mandibles. The method is applied to estimate age of death in 53 mandibles of juvenile wild boar and seasonality at the Late Mesolithic site of Ringklos

A Bayesian MCMC based estimation of Long memory in state space model

To estimate the long memory series in the framework of state space model is rarely documented although the theoretical foundation was well built in late 90s, and the literatures concentrate mainly on the estimation in stationary case. This paper aims to estimate the parameters in a wide range of long memory series by applying approximate Maximum Likelihood Estimation (MLE) and Bayesian Monte Carlo

Evidence of Low-dimensional Determinism in Short Time Series of Solute Transport

Investigating the vadose zone, the physics behind the temporal and spatial instabilities of flow (in unsaturated media) is still of question. Although chaotic approaches have been widely employed for identifying different surface hydrology processes, such as rainfall, runoff, lake volume, etc., they were not applied for subsurface systems as much. On this ground, the present study attempts to inve

Global Engagement and the Occupational Structure of Firms

Engagement in foreign markets can have an impact on firm organization and on the type of occupations that a firm needs. We examine the effect of globalization on the occupational mix using detailed Swedish data that cover all firms and a representative sample of the labor force for 1997-2005. We find a robust relationship between a firm’s degree of international integration and its occupational mi
