Interpreting protohistoric societies through place names of landscape features: a case study in València, Spain
2021
Protohistoric place names, created before written history and related to extinct languages, are analysed in this article. Our case study deals with place names of current towns (over 20,000 inhabit...
Changes of Commuting Range in Riga Agglomeration
2018
Abstract The aim of this paper is to characterise commuting trends in Riga agglomeration, while taking into account proximity to Riga and territorial accessibility. Changes of commuting range are looked at through literature analysis (historical context) and by using descriptive analysis and parametric tests (current situation). Results indicate that while both proximity to Riga and access to state level roads have a significant impact on commuting flows, it is the former which has a more significant impact.
Private Space in Soviet Cinema: Case Study of Riga
2018
Abstract The aim of this article is to discover the discourse of living spaces of Riga through the films of the Soviet period and to examine essential changes of private space in different residential structures. This study contributes to the field of human geography by conducting content analysis of a vast number of Soviet films with a focus on the development and spatial organization of apartments in Riga. The analysis of 264 films illustrates that living spaces are rarely portrayed in the Soviet cinema and they mostly provide intentionally formed idealistic information about the qualities and achievements of Soviet private space.
Generalized Camassa-Holm Equations: Symmetry, Conservation Laws and Regular Pulse and Front Solutions
2021
In this paper, we consider a member of an integrable family of generalized Camassa–Holm (GCH) equations. We make an analysis of the point Lie symmetries of these equations by using the Lie method of infinitesimals. We derive nonclassical symmetries and we find new symmetries via the nonclassical method, which cannot be obtained by Lie symmetry method. We employ the multiplier method to construct conservation laws for this family of GCH equations. Using the conservation laws of the underlying equation, double reduction is also constructed. Finally, we investigate traveling waves of the GCH equations. We derive convergent series solutions both for the homoclinic and heteroclinic orbits of the…
Agriculture intensity and landscape configuration influence the spatial use of wildcats across Europe
2023
Land use intensification is increasing worldwide and affects wildlife movements, particularly of specialist car-nivores. Resource availability and anthropogenic activities drive the extent and shape of home range size. Wildlife may respond to decreased resource availability under intensification scenarios by increasing their home ranges; however they may be less affected when inhabiting sustainable agricultural landscapes. We investigate whether agricultural practices and landscape configuration influence the spatial behaviour of wildcats, a medium-sized specialist carnivore inhabiting landscapes with different degrees of agricultural presence across Europe. We focus on the effect of the pr…
Hume’s Fork and Mixed Mathematics
2017
Abstract:Given the sharp distinction that follows from Hume’s Fork, the proper epistemic status of propositions of mixed mathematics seems to be a mystery. On the one hand, mathematical propositions concern the relation of ideas. They are intuitive and demonstratively certain. On the other hand, propositions of mixed mathematics, such as in Hume’s own example, the law of conservation of momentum, are also matter of fact propositions. They concern causal relations between species of objects, and, in this sense, they are not intuitive or demonstratively certain, but probable or provable. In this article, I argue that the epistemic status of propositions of mixed mathematics is that of matters…
Wintering habitats of Eleonora's FalconsFalco eleonoraein Madagascar
2012
[Capsule]: Eleonora's Falcons wintering in Madagascar selected degraded humid forests and cultivated areas close to pristine humid forest. [Aims]: To identify the habitat preferences of Eleonora's Falcon Falco eleonorae on their wintering grounds in Madagascar, and to use this information to gain insights into the conservation priorities of this species. [Methods]: A total of 11 Eleonora's Falcons were captured in Spain in 2007 and 2008 and equipped with solar-powered satellite transmitters. We obtained information on five complete wintering events for three birds, two of them tracked for two consecutive years. Data were analyzed using geographic information system-based cartography.

Effects of climate, land cover and topography on soil erosion risk in a semiarid basin of the Andes
2016
Understanding soil erosion processes in the Ecuadorian Andes with a tropical wet-dry climate and a variable topography, is fundamental for research on agriculture sustainable, environmental management, as well as for a stable water supply for the local populations. This work proposes method to estimate soil erosion risk in the semiarid Catamayo basin with limited data. The results show that the rainfall distribution and the erosivity along with the rugged topography, followed by the land cover (C-factor), are the most important factors to estimate soil erosion risk. The soil erodibility is the most important factor in the dry season for agricultural areas and where the ground cover is spars…
