Factors Influencing Point Measurement of Near-surface Saturated Soil Hydraulic Conductivity in a Small Sicilian Basin
2017
Hydraulic conductivity of saturated soil, Ks, controls many hydrological processes. Parameterization of basin hydrological models in terms of Ks is complicated and uncertain owing to the very high spatial variability of this soil property. A small Sicilian basin was intensively sampled by the simplified falling head technique to obtain spatially distributed Ks data, and an attempt to explain their spatial variability on the basis of soil physical characteristics, digital elevation model-derived topographic attributes and land cover was carried out. High Ks values were obtained when clay content was low and both elevation and mean slope were high. Moreover, differences in Ks among land cover…
Spatio-Temporal Analysis of Urban Acoustic Environments with Binaural Psycho-Acoustical Considerations for IoT-Based Applications
2018
Sound pleasantness or annoyance perceived in urban soundscapes is a major concern in environmental acoustics. Binaural psychoacoustic parameters are helpful to describe generic acoustic environments, as it is stated within the ISO 12913 framework. In this paper, the application of a Wireless Acoustic Sensor Network (WASN) to evaluate the spatial distribution and the evolution of urban acoustic environments is described. Two experiments are presented using an indoor and an outdoor deployment of a WASN with several nodes using an Internet of Things (IoT) environment to collect audio data and calculate meaningful parameters such as the sound pressure level, binaural loudness and binaural sharp…
Contrasting age-specific recruitment and survival at different spatial scales: A case study with the European storm petrel
2009
Evolutionary studies on optimal decisions or conservation guidelines are often derived by generalising patterns from a single population, while inter-population variability in life-history traits is seldom considered. We investigated here how survival and recruitment probabilities changed with age at different geographical scales using the encounter histories of 5523 European storm petrels from three Mediterranean colonies, and also how our estimates of these parameters might be expected to affect population growth rates using population matrix models. We recorded similar patterns among colonies, but also important biological differences. Local survival, recruitment and breeding success inc…
Spatial Cognition and Frames of Reference in Indo-European
2022
The development of Frames of Reference (FoRs) as coordinate systems in space language has gained increasing attention in current linguistic, neurolinguistic, and psycholinguistic research (Diessel 2013: 687; Kemmerer 2010). Previous studies on typology of spatial expressions have traditionally been based on the universal status of the egocentric or relative FoR found in the Indo- European languages, in which the relation between Figure and Ground is specified by the deictic observer’s viewpoint (Mühlhäusler 2001). However, there is growing crosslinguistic evidence that many non-Indo-European languages do not make use of such deictic or ternary FoR, but interpret spatial relations by referri…
Measuring agglomeration by spatial effects: a proposal
2015
In this paper we examine the influence of spatial dependence on the estimation of the effect of standard measures of agglomeration on local growth. The hypothesis is that the forces of agglomeration do not use up their effects inside a single local area but extend to wider geographic areas, particularly on the adjacent territories. To account for these spatial effects, we propose a modification of the traditional agglomeration index, suggested by Maurel and Sedillot (1999), including both agglomeration of economic activity within an area and neighbour effects, that is, the effect of agglomeration that comes from neighbouring areas. In the empirical exercise we compute the a-spatial and the …
