Damage caused by ungulates to agricultural areas are difficult to evaluate because the real extent of the damage remains usually poorly described and potentially arising conflicts. Recent advances in unmanned aerial system (UAS) provide new versatile mapping and quantification possibilities in a wide range of applications. We used crop fields (Zea mays) damaged by wild boar (Sus scrofa) and compared the extent of the damage by means of three methods: i) traditional ground-based assessment ii) UAS orthoimages with operator delineation and iii) UAS Crop Height Model with automatic delineation based on height threshold. We showed for the first time that UAS could be applied for assessing damage of ungulates to agriculture. The two methods using UAS imagery provide coherent and satisfactory results and trended to underestimate the damage area when compared to in-use ground-based field expertise. However we suggest that performance of UAS should further be tested in variable conditions in order to assess the broad application of this tool. Our study describes the potential of UAS as a tool for estimating more accurately the damage area and subsequently the compensation costs for wildlife damage. The proposed approach can come in support of local and regional policies for the definitions of compensation for farmers. [less ▲]

Let k >= 2 be an integer. A set X of integers is k-recognizable if the language of k-ary representations of the elements in X is accepted by a finite automaton. The celebrated theorem of Cobham from 1969 states that if a set of integers is both k-recognizable and ℓ-recognizable, then it is a finite union of arithmetic progressions. We present several extensions of this result to nonstandard numeration systems, we describe the relationships with substitutive and automatic words and list Cobham-type results in various contexts.

Dans cet article, nous nous intéressons à la prise en charge des chômeurs par les opérateurs privés d’emploi. Les services publics de l’emploi doivent partager le marché de l’accompagnement des demandeurs d’emploi avec des prestataires de service qui ont, désormais, pour mission d’organiser l’accompagnement et la formation des chômeurs. Des collaborations naissent entre acteurs privés et publiques sous la forme de « partenariats publics-privés », dans une relation de « délégation » de la mission du service public. Cette gestion « mixte » du marché de l’emploi pose question au niveau de la gestion des ressources publiques par les acteurs privés. Notre enquête, réalisée en Belgique francophone, propose de regarder les effets de cette gestion à travers les défis que pose le marché de l’accompagnement des chômeurs. Les résultats mettent en évidence le développement par les acteurs privés de stratégies « clandestines » pour contourner les problèmes rencontrés lors de la collaboration. Nous verrons dans quelle mesure celles-ci ont un effet sur le parcours d’insertion des demandeurs d’emploi ainsi que la manière dont les agents des services partenariats des services publics de l’emploi gèrent ses stratégies.

Children have always been considered as vulnerable subjects. In the course of time, the intervention of the law for ensuring their protection has grown, and the notion of "best interest" of the child has been shaped as a central one in this context. The contribution aims at examining the role of the Courts in the European territory (both the European Court of Human Rights and the European Court of Justice) and the convergences or differences in the respective case-law on this topic.

The famous Doignon-Bell-Scarf theorem is a Helly-type result about the existence of integer solutions to systems of linear inequalities. The purpose of this paper is to present the following quantitative generalization: Given an integer k, we prove that there exists a constant c(n,k), depending only on the dimension n and on the number k, such that if a bounded polyhedron {x in R^n : Ax <= b} contains exactly k integer points, then there exists a subset of the rows, of cardinality no more than c(n,k), defining a polyhedron that contains exactly the same k integer points. In this case c(n,0)=2^n as in the original case of Doignon-Bell-Scarf for infeasible systems of inequalities. We work on both upper and lower bounds for the constant c(n,k) and discuss some consequences, including a Clarkson-style algorithm to find the l-th best solution of an integer program with respect to the ordering induced by the objective function.

The well-studied semigroup Sg(A) = {b : b = Ax; x in Z^n; x >= 0} can be stratified by the sizes of the polyhedral fibers IPA(b) = {x : Ax = b; x >= 0; x in Z^n}. The key theme of this paper is a structure theory that characterizes precisely the set Sg_k(A) of all vectors b in Sg(A) such that their fiber IPA(b) has at least k-solutions. We demonstrate that this set is finitely generated, a union of translated copies of a semigroup which can be computed explicitly via Hilbert bases computations. Related results can be derived for those right-hand-side vectors b for which IPA(b) has exactly k solutions or fewer than k solutions. We also show that, when n, k are fixed natural numbers, one can compute in polynomial time an encoding of Sg_k(A) as a generating function, using a short sum of rational functions. As a consequence, one can identify all right-hand-side vectors that have at least k solutions. Using this tool we prove that for fixed n; k the k-Frobenius number can be computed in polynomial time, generalizing a well-known result of R. Kannan. [less ▲]

Science and technology require an intervention by the law, and law is called upon to intervene in front of their evolution, and to look for proper solutions of governance and rational responses to their risks. One of the main issues to be investigated from the legal viewpoint is represented by the ‘dual-use dilemma’ that arises both in ‘traditional’ and new areas of techno-sciences. Indeed, any kind of research has the potential to be used both for bad as well as for good purposes. Therefore, it is important to reflect upon the ways to control possibly dangerous research without preventing the progress from going further. Such ‘dual-use dilemma’, then, entails the study of one of the fundamental freedoms in the biolaw area: the freedom of scientific research, its limits, and relationship with other rights/needs/freedoms (such the need of security). This work focuses on two areas of the techno-scientific world. One is more ‘traditional’, i.e. nuclear science, in whose context the reflections on ‘dual-use’ were born and developed, and the other one is a new emerging technology, which is synthetic biology. The aim is to understand how the freedom of scientific research could be shaped in relationship with other rights/needs/interests for dealing with ‘dual-use’ issues in the aforementioned areas of science and technology.
