  • that the surface pollen assemblages reflect the vegetation quite well. Cluster analysis and principal components analysis of pollen assemblages can distinguish forest and non-forest vegetation well. The former method is better at separating pine and mixed forests
  • In the catchment of South Luohe River, in the transitional zone between south and north China, 40 surface samples under 10 vegetation types were collected to reveal the relationship between pollen assemblages and vegetation. The results show

  • Radionuclide dating of recent sediment and the validation of pollen-environment reconstruction in a small watershed reservoir in southeastern China
  • Accumulation rate ; Charcoal ; China ; Chronostratigraphy ; Dam ; Environmental change ; Geochemistry ; Guangdong ; Human impact ; Isotope analysis ; Lacustrine sediment ; Palaeo-environment ; Palynology ; Pollen diagram ; Reservoir ; Watershed
  • . The results show that the sedimentation rate of the Huangdong Reservoir is relatively high, implying that soil erosion and water loss were strong. Pollen and micro-charcoal analysis were performed to test the reliability of pollen-based environment
  • A 76 cm sediment core was collected from the Huangdong Reservoir (near Liangjing village, Guangdong Province). The radionuclides 137Cs and 210Pb and sediment grain size analysis were applied to establish the chronology and modern sedimentation rates
  • setting in spite of low absolute values. The AA. conclude that the environmental proxies, such as grain size, pollen, and charcoal, are sufficiently sensitive to reveal local ecosystem changes caused by natural disasters or human activity.

  • Global sensitivity analysis of a large agent-based model of spatial opinion exchange : a heterogeneous multi-GPU acceleration approach
  • Analysis of variance ; Model ; Spatial analysis
  • The objective focuses on the sensitivity analysis of large agent-based modeling of spatial opinion exchange, accelerated using multiple graphics processing units (GPUs). It is conducted using a variance-based approach, requiring numerous model runs
  • for Monte Carlo integration. Experimental results indicate GPU-accelerated general-purpose computation provides an efficacious and feasible solution for the sensitivity analysis of large agent-based models. The heterogeneous parallel computing approach

  • Land use change in New Spain : a three-dimensional historical GIS analysis
  • This article focuses on a case study area in New Spain, roughly equivalent to present-day Mexico, wherein forty-seven sheep ranches were established through viceregal land grants between 1535 and 1610. An integration of fieldwork, textual analysis
  • of land grants, and imagery analysis enables these ranches to be mapped in a three-dimensional geographic information system environment. The key findings are that grantees harbored a persistent preference for south-facing land; ranches clustered most

  • Arid area ; Bank erosion ; Drainage network ; Geomorphometry ; Hydrology ; Hypsometry ; Jordan ; Regression analysis ; Sediment budget ; Wadi ; Watershed
  • This study addresses the morphometric variables that determine the sediment yield in Wadi Al-Arja through the analysis of the impact of different morphometric characteristics along the course of the valley on its sediment yield, as well
  • as the analysis of spatial and formal dimensions and morphologies of the basin and its relationship to the sediment yield. The study also addresses the size of variation in the volume of sediment yield of the river tributaries that make up the water network
  • of the valley under the differences of its morphometric and hydrological characteristics. The results of the step-wise regression analysis confirmed the importance of the morphometric and hydrological variables, and plant coverage in interpreting the variation

  • This article investigates the spatial distribution of aging communities of the Aichi Prefecture in Japan using a standard correlation analysis and bivariate local spatial statistic analysis. The results suggest that using both indices allows us
  • to capture different types of aging communities in diverse contexts (e.g. depopulated rural areas, pockets of aging communities in urban areas, and growing concentrations of aging population in the suburbs). The analysis uses data sets aggregated at different

  • Binding aross-border regions : an analysis of cross-border governance in Lille-Kortrijk-Tournai Eurometropolis
  • This paper investigates the governance of the cross-border transit system in Eurometropolis of Lille-Kortrijk-Tournai between France and Belgium. It relies on a qualitative analysis of actors and institutions as well as social network analysis
  • to more precisely fix the positions and roles of actors on either side of the border. The new cross-border institution, the EGTC agency, is a central actor in public transit policy networks and its function is more complex than the institutional analysis
