A decomposition approach for multidimensional knapsacks with family-split penalties
2022
The optimization of Multidimensional Knapsacks with Family-Split Penalties has been introduced in the literature as a variant of the more classical Multidimensional Knapsack and Multi-Knapsack problems. This problem deals with a set of items partitioned in families, and when a single item is picked to maximize the utility, then all items in its family must be picked. Items from the same family can be assigned to different knapsacks, and in this situation split penalties are paid. This problem arises in real applications in various fields. This paper proposes a new exact and fast algorithm based on a specific Combinatorial Benders Cuts scheme. An extensive experimental campaign computational…
Villes, densité et fractalité
1995
International audience; Ce bref article résumé les résultats d'analyses fractales effectuées sur les villes françaises à plusieurs dates pour deux niveaux d'observation: les tissus urbains caractérisés par la distribution spatiale des surfaces bâties d'une part, et le semis des villes de différentes tailles dans l'ensemble du territoire français d'autre part. Les méthodes de mesure sont rapidement expliquées, l'accent est mis sur la signification des nombres obtenus, leur comparaison d'une ville à l'autre et leur évolution au cours du temps.

Approximate Taylor methods for ODEs
2017
Abstract A new method for the numerical solution of ODEs is presented. This approach is based on an approximate formulation of the Taylor methods that has a much easier implementation than the original Taylor methods, since only the functions in the ODEs, and not their derivatives, are needed, just as in classical Runge–Kutta schemes. Compared to Runge–Kutta methods, the number of function evaluations to achieve a given order is higher, however with the present procedure it is much easier to produce arbitrary high-order schemes, which may be important in some applications. In many cases the new approach leads to an asymptotically lower computational cost when compared to the Taylor expansio…
The Supremacy of the Constructivist Approach in the Field of Physics Education: Myths and Real Challenges
2012
We intend, first of all, to show that the supposed 'supremacy of the constructivist epistemology' in the field of physics teaching is just a myth that hides the actual supremacy of the ineffective transmission/reception model. We then centre our analyses and proposals on the real challenges to improve students' learning and attitudes. Résumé Nous essayons de montrer que la prétendue « suprématie de l'épistémologie constructiviste » dans le domaine de la didactique de la physique n'est qu'un mythe, qui cache la suprématie effective du modèle inefficace de la transmission/réception. Nous centrons ensuite nos analyses et propositions sur les défis réels pour améliorer l'apprentissage et les at…
Metodi digitali per l'insegnamento classico e umanistico
2020
Il volume propone una riflessione critica di carattere metodologico su alcuni strumenti e tecniche digitali per l'insegnamento scolastico ed universitario in ambito umanistico, con un'attenzione particolare alla didattica delle lingue, letterature e culture classiche. Per ciascuno strumento digitale, si valuta se esso comporti un effettivo miglioramento dal punto di vista dei metodi, alla luce di alcuni obiettivi e principi educativi generali: sono presentate e discusse solo innovazioni digitali che, in chiave costruttivista, rendano l'apprendimento più attivo, più critico, più creativo e più orientato verso un contributo positivo alla società. Una serie di proposte didattiche accompagna la…
Dreams and Trauma Changes in the Manifest Dreams in Psychoanalytic Treatments - A Psychoanalytic Outcome Measure.
2021
Although psychoanalysts are interested in symptom reduction as an outcome, they are looking for instruments to measure sustaining changes in the unconscious mental functioning. In this article it is discussed that conceptually well-founded transformation of manifest dreams analyzed with precise empirical methods could be considered as a promising indicator for such therapeutic changes. We are summarizing a dream generation model by Moser and von Zeppelin which has integrated a large interdisciplinary knowledge base of contemporary dream and sleep research. Based on this model the authors have developed a valid and reliable coding system for analyzing manifest dreams, the Zurich Dream Proces…
Recent Advances on the Halo- and Cyano-Trifluoromethylation of Alkenes and Alkynes
2021
Incorporation of fluorine into organic molecules is a well-established strategy in the design of advanced materials, agrochemicals, and pharmaceuticals. Among numerous modern synthetic approaches, functionalization of unsaturated bonds with simultaneous addition of trifluoromethyl group along with other substituents is currently one of the most attractive methods undergoing wide-ranging development. In this review article, we discuss the most significant contributions made in this area during the last decade (2012−2021). The reactions reviewed in this work include chloro-, bromo-, iodo-, fluoro- and cyano-trifluoromethylation of alkenes and alkynes.
Interspace for empathy : engaging with work-related uncertainty through artistic intervention in management education
2022
How can artistic intervention facilitate empathic engagement with work-related uncertainty in postgraduate management education? To examine this, we theorize artistic intervention as creating an interspace of temporarily suspended organizational norms through which empathy as relational knowing can emerge between participants. Drawing on an ethnographic study entitled Becoming in Academia, a nine-month artistic intervention conducted by a group of doctoral students in a Nordic business school (NBS), this paper highlights how an interspace for empathic engagement with work-related uncertainty was created by the participants through three intervention activities: aligning oneself to the other…
Leishmania tarentolae and Leishmania infantum in humans, dogs and cats in the Pelagie archipelago, southern Italy.
2021
Visceral leishmaniasis (VL) caused by Leishmania infantum is endemic in the Mediterranean basin with most of the infected human patients remaining asymptomatic. Recently, the saurian-associated Leishmania tarentolae was detected in human blood donors and in sheltered dogs. The circulation of L. infantum and L. tarentolae was investigated in humans, dogs and cats living in the Pelagie islands (Sicily, Italy) by multiple serological and molecular testing. Human serum samples (n = 346) were tested to assess the exposure to L. infantum by immunofluorescence antibody test (IFAT), enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) and to L. tarentolae by IFAT. Meanwhile, sera from do…
