La dérive pédagogique parallèle. Un fil éducatif invisible entre Porto et Paris à travers des récits personnels
2019
Partimos de la deriva como práctica artística contemporánea, con reconocidos antecedentes históricos. El objetivo principal es experimentar las potencialidades pedagógicas de la observación de entornos urbanos de forma colaborativa y mediada por las TIC a través de la deriva, como artistas/investigadores/docentes encargados de la formación del profesorado, para poder introducir este tipo de iniciativas en el entorno educativo. La A/R/Tografía como método de Investigación Basada en las Artes facilita usar la deriva simultáneamente como práctica artística, proceso investigador y experiencia de aprendizaje docente. Los resultados se exponen a través de narrativas personales que muestran reflex…
Forretningsorientert prosjektutvikling : forprosjektrapport til Byggherren i fokus (BIF)
2005
Denne forprosjektrapporten er utarbeidet på oppdrag av Byggherren i fokus v/NBBL, og diskuterer den faglige basisen for å starte opp hovedprosjekter forankret i økonomisk teori innen forretningsbasert prosjektutvikling i byggebransjen. Det skisseres tre mulige omtråder for videre analyse i et hovedprosjekt: Priser og prismodeller for fast eiendom, usikkerhet og realopsjonsanalyse samt markeds- og reguleringssvikt. I forbindelse med hvert av temaene gjennomgås relevant økonomisk teori som basis for videre anlyse i et evenuelt hovedprosjekt.
Existence of minimizers for eigenvalues of the Dirichlet-Laplacian with a drift
2015
Abstract This paper deals with the eigenvalue problem for the operator L = − Δ − x ⋅ ∇ with Dirichlet boundary conditions. We are interested in proving the existence of a set minimizing any eigenvalue λ k of L under a suitable measure constraint suggested by the structure of the operator. More precisely we prove that for any c > 0 and k ∈ N the following minimization problem min { λ k ( Ω ) : Ω quasi-open set , ∫ Ω e | x | 2 / 2 d x ≤ c } has a solution.
Alignment for the first precision measurements at Belle II
2019
On March 25th 2019, the Belle II detector recorded the first collisions delivered by the SuperKEKB accelerator. This marked the beginning of the physics run with vertex detector. The vertex detector was aligned initially with cosmic ray tracks without magnetic field simultaneously with the drift chamber. The alignment method is based on Millepede II and the General Broken Lines track model and includes also the muon system or primary vertex position alignment. To control weak modes, we employ sensitive validation tools and various track samples can be used as alignment input, from straight cosmic tracks to mass-constrained decays. With increasing luminosity and experience, the alignment is …
Mutamento del giudice e rinnovazione della prova: la Corte costituzionale esorbita dai confini accusatori
2020
The “Judge of the laws” delivers to the Parliament punctuals directives to give concreteness to the reasonable duration of the trial. What is at stake is the right to renew the evidence in the event of a change of the judge, which is drastically reduced to prevent it from being used merely for dilatory purposes. The Author criticizes the decision in question, fearing a dangerous drift: the renewal only of the “useful” evidence.
Pleistocene allopatric differentiation followed by recent range expansion explains the distribution and molecular diversity of two congeneric crustac…
2021
AbstractPleistocene glaciations had a tremendous impact on the biota across the Palaearctic, resulting in strong phylogeographic signals of range contraction and rapid postglacial recolonization of the deglaciated areas. Here, we explore the diversity patterns and history of two sibling species of passively dispersing taxa typical of temporary ponds, fairy shrimps (Anostraca). We combine mitochondrial (COI) and nuclear (ITS2 and 18S) markers to conduct a range-wide phylogeographic study including 56 populations of Branchinecta ferox and Branchinecta orientalis in the Palaearctic. Specifically, we investigate whether their largely overlapping ranges in Europe resulted from allopatric differe…
The value proposition of food delivery apps from the perspective of theory of consumption value
2021
Purpose The theory of consumption values (TCV) has successfully explained much consumer choice behavior, but few studies have investigated the values that drive food-delivery application (FDA) use. This study aims to bridge this gap by extending the TCV to the FDA context to examine food consumption-related values and interpreting and rechristening generic consumption values to adapt the TCV to the FDA context. Design/methodology/approach An explorative mixed-method research approach was taken to conduct focus group discussions with 20 target users to develop the questionnaire and then administer it for a cross-sectional survey (pen and pencil) to FDA users aged 22–65 years; 423 complete r…
Inter-relazioni tra pools di C organico e gruppi funzionali della sostanza organica in un suolo a diversa gestione agronomica
2013
Lavorazioni del suolo e rotazioni colturali giocano un ruolo chiave nell’influenzare sia la quantità sia la qualità della sostanza organica del suolo (SOM). Mentre diversi studi sono stati condotti per valutare gli effetti di tali fattori agronomici sui pools di C organico, anche lungo i profili di suolo, pochi altri hanno investigato anche le relazioni tra i diversi pools di C organico e i gruppi funzionali della SOM. Obiettivi del presente lavoro sono stati quelli di i) valutare gli effetti della lavorazione del suolo e delle rotazioni colturali sui diversi pools di C organico e ii) di investigare le relazioni intercorrenti tra tali pools e i gruppi funzionali della SOM. I campioni di suo…
Do island plant populations really have lower genetic variation than mainland populations? Effects of selection and distribution range on genetic div…
2015
Ecological and evolutionary studies largely assume that island populations display low levels of neutral genetic variation. However, this notion has only been formally tested in a few cases involving plant taxa, and the confounding effect of selection on genetic diversity (GD) estimates based on putatively neutral markers has typically been overlooked. Here, we generated nuclear microsatellite and plastid DNA sequence data in Periploca laevigata, a plant taxon with an island–mainland distribution area, to (i) investigate whether selection affects GD estimates of populations across contrasting habitats; and (ii) test the long-standing idea that island populations have lower GD than their mai…
The Large Area Detector onboard the eXTP mission
2022
The Large Area Detector (LAD) is the high-throughput, spectral-timing instrument onboard the eXTP mission, a flagship mission of the Chinese Academy of Sciences and the China National Space Administration, with a large European participation coordinated by Italy and Spain. The eXTP mission is currently performing its phase B study, with a target launch at the end-2027. The eXTP scientific payload includes four instruments (SFA, PFA, LAD and WFM) offering unprecedented simultaneous wide-band X-ray timing and polarimetry sensitivity. The LAD instrument is based on the design originally proposed for the LOFT mission. It envisages a deployed 3.2 m2 effective area in the 2-30 keV energy range, a…
