Deciphering field-based evidences for crop allelopathy in weed regulation
2022
It is now essential to reduce the negative impacts of weed management and especiallyherbicide use. Weed-suppressive crop species/varieties hold promise for integrated andsustainable weed regulation. Competition for resources and allelopathy are the two mainunderlying mechanisms. Unlike competition, which is well studied and established, allelopathyby living crops remains a contentious mechanism. Although it is recognized that plants emit alarge number of substances, the effective role of these molecules is very challenging todemonstrate in the field. A major difficulty to dissociate the effects of allelopathy from thoseof competition for resources.Here we systematically and quantitatively r…

Computational strategies to model the interaction and the reactivity of biologically-relevant transition metal complexes
2022
Abstract Transition metal atoms possess the unique capacity to induce significant changes in the electronic structure of their ligands, often culminating in substantial modification of their chemical behavior, and this ability explains well their evolutionary incorporation into the living matter. Exactly this complexity of metal atom behaviours on the electronic level is the reason of various quantum chemistry strategies have been developed for their description. On the other hand, the application of quantum chemistry methodologies to gain a comprehensive understanding of the interaction between metal and biological matter, can only be approached through adequate modelling of the chemical p…
Validez y reproducibilidad de una rúbrica para el análisis de la expresividad en la danza
2022
La danza es una disciplina artística que combina la destreza del movimiento corporal con la expresividad de emociones, sentimientos e ideas. Sin embargo, generalmente la expresividad queda en segundo plano tanto en el proceso de enseñanza como en su evaluación. En ese sentido, el objetivo del presente estudio fue diseñar y validar una rúbrica para evaluar la expresividad en la danza en general, así como valorar su reproducibilidad inter-evaluador y su aplicación en dos grupos de bailarines/as. Ambos grupos se aprendieron una misma coreografía con la diferencia de que solo uno de ellos fue conocedor de la rúbrica. Dicha coreografía fue grabada en vídeo para posteriormente ser evaluada por do…

Intelligibility and the gravity of segmental deviations in L1 Finnish speakers’ L2 English
2022
The goal of English pronunciation teaching has shifted from native-likeness to intelligibility. Especially in EFL contexts, pushing learners to sound like L1 speakers is difficult to justify, whereas becoming intelligible is an easily justifiable, practical learning goal. However, EFL teachers often emphasize the sounds that are typically challenging for their learners, even though all sounds are not equally important for intelligibility. The present study is focussed on the extent to which segmental deviations can compromise intelligibility. Speech samples were elicited from teenaged L1 Finnish learners of English, demonstrating segmental deviations typical of the target group. To evaluate…
Polémoformes et zones humides dans la Montagne de Reims (Marne, France) – apport du lidar aéroporté
2022
Les morphologies liées aux conflits armés ou « polémoformes »déterminent potentiellement des zones humides sous la forme de mares ou d’étangs sur d’anciens champs de bataille. Ces milieux, fortement modifiés par la pédoturbation, et la bombturbation voire par des contaminations (ETM), constituent pourtant des ilots de biodiversité à forte valeur patrimoniale (Forêt d’exception, Réserves dirigées, ZNIEFF). C’est le cas de la Montagne de Reims, terminaison orientale de la côte d’Ile de France dominant la Champagne et coiffée par la formation des Argiles à meulières.L’objectif de cette contribution est de caractériser les polémoformes de la Montagne de Reims, située en arrière de la 4ème posit…
Market Timing Using Artificial Neural Networks
2022
The emergence of artificial neural networks has given us some of the most impressive technological tools. Inspired by the human brain, these networks consist of interconnected artificial neurons that can detect patterns invisible to the human eye. These qualities have caught the attention of investors seeking ways to beat the market. In this thesis, we explore how artificial neural networks can be used to construct an active trading strategy and evaluate the strategy's performance against two benchmark strategies. Two stock indices were used to train neural networks using the lagged return as input to predict the market state. By using the networks' predictions, an active trading strategy w…

The Potential Role of Metabolomics in Drug-Induced Liver Injury (DILI) Assessment.
2022
Drug-induced liver injury (DILI) is one of the most frequent adverse clinical reactions and a relevant cause of morbidity and mortality. Hepatotoxicity is among the major reasons for drug withdrawal during post-market and late development stages, representing a major concern to the pharmaceutical industry. The current biochemical parameters for the detection of DILI are based on enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP)) and bilirubin serum levels that are not specific of DILI and therefore there is an increasing interest on novel, specific, DILI biomarkers discovery. Metabolomics has emerged as…
Frequency locking of a breather fibre laser, fairy tree and devil's staircase
2022
Breathing solitons exhibiting periodic oscillatory behaviour form an important part of many different classes of nonlinear wave systems. Recently, thanks to the development of real-time detection techniques, they have also emerged as a ubiquitous mode-locked regime of ultrafast fibre lasers [1,2]. The excitation of breather oscillations in a laser naturally triggers a second characteristic frequency in the system, which therefore shows competition between the cavity repetition frequency and the breathing frequency. The theoretical model describing nonlinear systems with two competing frequencies predicts frequency locking, in which the system locks into a resonant periodic response featurin…

Bestim network : stimulating plant health in agroécological systems
2022
The evolution of agriculture is facing strong societal expectations. One of them is to drasticallyreduce the use of synthetic inputs and in particular of plant protection products (PPP). In response,farmers and professionals in charge of agricultural development must invent a so-called "agroecological" agriculture, by ensuring profitability and sustainability of production systems and byimplementing a combination of many levers. The BESTIM network is part of this logic and proposes theconcept of "agroecological immunity" which aims to optimize the stimulation of plant health in efficientagroecological systems. We’ve adapted the concept of ecological immunity initially described in theanimal…

L’hypermobilité à l’épreuve des enjeux environnementaux et sociétaux.
2022
Alors que l’on prophétise, à l’aune de la crise sanitaire, un changement radical des pratiques touristiques pour aller vers un tourisme de proximité qui peut se lire comme un oxymore et que certains modes de transport, l’avion en particulier, ou certaines formes touristiques, telles que la croisière maritime font l’objet de critique quant à leur impact environnemental et/ou sociétal, nous nous sommes penchés sur une catégorie de touristes, qualifiés d’hypermobiles. Il s’agit de comprendre leurs pratiques et les motivations qui guident une activité touristique supérieure à la moyenne nationale. L’analyse a été menée en deux temps. Une première analyse quantitative basée sur des traitements s…
Social Services, Social Innovation and Multi-Actor Collaboration: A Civil Society Organisation Perspective
2022
A central focus of this PhD dissertation is to advance an understanding of how social innovation is generated through the perspective of civil society organisations (CSOs) that provide social services to vulnerable groups through collaboration with multiple actors in the fragile context, with a legacy of war. An “agency-structure” approach has been applied as an overarching perspective throughout this dissertation. Theories such as institutional theory (new institutionalism and institutional networking), resource-dependency theory as well as the concepts of social innovation, collaboration, non-state service provision, NGO-isation and the third sector-public services provision present the m…
Individualized Power Training Based on the Theoretical Force-Velocity Profile: Efficient or too many pitfalls?
2022
Hensikt: Målet med denne studien var å utforske om et individualisert power-treningsprogram som er basert på den teoretiske individuelle kraft-hastighetsprofilen (KH) er mer effektiv enn et balansert power-treningsprogram for å forbedre sprint- og hopprestasjon. Metode: Førti nasjonale eliteutøvere fra håndball og fotball (alder 22 ± 4, høyde 183 ± 10 og kroppsmasse 84 ± 15) gjennomførte en 10-ukers treningsintervensjon. Utøvernes teoretiske optimale kraft-hastighetsprofilen ble utviklet med knebøyhopp med forskjellig belastning (0,20,40,60.80 kilogram), og basert på utøvernes KH-profil så ble de kategorisert som enten kraft- eller hastighetsdominante. Gjennom randomisering ble utøverne pla…

'To Leave or to Remain': Trauma, Loss and the Reinvention of the Self in Rachel Cusk’s Outline trilogy
2022
This thesis will examine trauma and loss in Rachel Cusk’s Outline trilogy: Outline (2014), Transit (2016) and Kudos (2018), and how it opposes and supplements another narrative, that of conversion and the reinvention of the self. I will track the tension between the model of personal trauma and loss of the main character and the conversion or rebirth narrative that unfolds in the novels. The trilogy introduces us to Faye, a writer who has recently divorced her husband after seven years of marriage and who is living alone with their two sons. This shock of modern life is something Faye, over the course of three novels, tries to cope with – she searches for a new way of living in the world. B…

Hypothesis testing for Panels of Semi-Markov Processes with parametric sojourn time distributions
2022
This work deals with the asymptotic properties of maximum likelihood estimators for semi-Markov processes with parametric sojourn time distributions. It is motivated by the comparison, via a two-sample test procedure, of the distribution of two panels of qualitative trajectories modeled by semi-Markov processes and observed over a random number of transitions. Considering first one panel of growing size, we derive, under classical conditions, the convergence in probability of the estimators of the transition probabilities and the parameters of the sojourn time distributions as well as their asymptotic normality. We then consider panels of semi-Markov processes drawn from two different popul…

Il lavoro sociale nei servizi dell’accoglienza a rifugiati e richiedenti asilo in Italia
2022
Mediante una rassegna sintetica di studi e ricerche, il capitolo propone spunti per l’analisi di un particolare aspetto del sistema italiano di prima e seconda accoglienza di rifugiati e richiedenti asilo: gli operatori e le operatrici dei servizi. Gli studi sulla violenza di prossimità subita da migranti, principalmente di genere femminile, in transito nei centri per rifugiati e richiedenti asilo e sulla presa in carico da parte dei servizi sociosanitari segnalano criticità: alcune di esse concernono aspetti strutturali del sistema di accoglienza (normativa di riferimento), altre ineriscono ai criteri discrezionali propri dei centri. La carenza sia di figure competenti sia di uniformità e …
RENAL SALT WASTING: UNA SINDROME DA INAPPROPRIATA SECREZIONE DI URODILATINA? UNO STUDIO PILOTA
2022
La Renal Salt Wasting Syndrome (RSW) è una sindrome clinica con caratteristiche di laboratorio che si sovrappongono completamente alla sindrome da secrezione inappropriata di ADH (SIADH). La differenza fondamentale tra le due sindromi risiede nel volume extracellulare (ECV), ridotto nella RSW e normale o leggermente aumentato nella SIADH. Le difficoltà nella diagnosi differenziale di questa sindrome e nella comprensione del preciso meccanismo patogenetico hanno contribuito a mettere in discussione l'esistenza stessa di RSW. Considerando le caratteristiche della RSW, è stato studiato il possibile ruolo dei peptidi natriuretici per spiegare la sua patogenesi come ANP e BNP, con risultati inso…
