Résumé :

The chemical speciation of copper in stream waters from Rutor Glacier was determined by cathodic stripping voltammetry with ligand competition against salicylaldoxime. The complexation of salicylaldoxime was calibrated at various calcium concentrations, the major competing cation in these waters. Copper concentrations (3–7 nM) were approximately ten-fold lower than typical for rain waters in this region, indicating that copper had been removed by adsorption onto rock and other particles. Strong copper binding ligands, with log K′CuL = 12.5–12.9, were detected in all samples, including waters emerging from beneath the glacier, with no detectable change in the ligand composition down stream. The results suggest that the ligands could originate from in situ production from algae in snow and ice, or directly from the precipitation.

Résumé :

Rumor propagation and refutation form an important issue for spreading dynamics in online social networks (OSNs). In this paper, we introduce a novel two-stage rumor propagation and refutation model with time effect for OSNs. The dynamical mechanism of rumor propagation and refutation with time effect is investigated deeply. Then a two-stage model and the corresponding mean-field equations in both homogeneous and heterogeneous networks are obtained. Monte Carlo simulations are conducted to characterize the dynamics of rumor propagation and refutation in both Watts–Strogatz network and Barabási–Albert network. The results show that heterogeneous networks yield the most effective rumor and anti-rumor spreading. Besides, the sooner authority releases anti-rumor and the more attractive anti-rumor is, the less rumor influence is. What’s more, these findings suggest that individuals’ ability to control themselves and identify rumor accurately should be improved to reduce negative impact of rumor effectively. The results are helpful to understand better the mechanism of rumor propagation and refutation in OSNs.

Résumé :

Rumor spreading is a good sample of spreading in which human beings are the main players in the spreading process. Therefore, in order to have a more realistic model of rumor spreading on online social networks, the influence of psycho-sociological factors particularly those which affect users’ reactions toward rumor/anti-rumor should be considered. To this aim, we present a new model that considers the influence of dissenting opinions on those users who have already believed in rumor/anti-rumor but have not spread the rumor/anti-rumor yet. We hypothesize that influence is a motive for the believers to spread their beliefs in rumor/anti-rumor. We derive the stochastic equations of the new model and evaluate it by using two real datasets of rumor spreading on Twitter. The evaluation results support the new hypothesis and show that the novel model which is relied on the new hypothesis is able to better represent rumor spreading.

Résumé :

In this paper, we propose a model to investigate how truth affects rumor diffusion in online social media. Our model reveals a relation between rumor and truth — namely, when a rumor is diffusing, the truth about the rumor also diffuses with it. Two patterns of the agents used to identify rumor, self-identification and passive learning are taken into account. Combining theoretical proof and simulation analysis, we find that the threshold value of rumor diffusion is negatively correlated to the connectivity between nodes in the network and the probability β of agents knowing truth. Increasing β can reduce the maximum density of the rumor spreaders and slow down the generation speed of new rumor spreaders. On the other hand, we conclude that the best rumor diffusion strategy must balance the probability of forwarding rumor and the probability of agents losing interest in the rumor. High spread rate λ of rumor would lead to a surge in truth dissemination which will greatly limit the diffusion of rumor. Furthermore, in the case of unknown λ, increasing β can effectively reduce the maximum proportion of agents who do not know the truth, but cannot narrow the rumor diffusion range in a certain interval of β.

Résumé :

Purpose In the wake of a rumor outbreak, individuals exchange three types of messages: rumor messages, counter-rumor messages, and uncertainty-expressing messages. However, the properties of the three types of messages are relatively unknown particularly in the social media context. Hence, the purpose of this paper is to examine these three types of messages posted on social media in the wake of a rumor outbreak. Design/methodology/approach Data included tweets posted after the outbreak of a rumor that wrongly accused the fast food chain Kentucky Fried Chicken (KFC) for selling rats instead of chicken. Using a deductive approach, codes were derived via content analysis on the tweets. Volume and exposure of tweets were also examined. Findings Counter-rumor tweets (52 percent) outnumbered rumors tweets (32 percent) and uncertainty-expressing tweets (16 percent). Emotions and personal involvement were abundant in rumor tweets. Expressions of credence and references to URLs were high in counter-rumor tweets. Social ties were found widely in uncertainty-expressing tweets. The high volume and exposure of counter-rumor tweets compared with those of either rumor tweets or uncertainty-expressing tweets highlight the potential of counter-rumors to mitigate rumors. Originality/value This research ventures into a relatively unexplored territory by concurrently examining rumor messages, counter-rumor messages and uncertainty-expressing messages in the wake of a rumor outbreak. It reveals that counter-rumor messages have the potential to mitigate rumors on social media.

Résumé :

This article analyzes the effects of rumor and official rumor clarification on Chinese stock returns under different rumor conditions using an event study. The results are based on a sample of 832 rumor clarification announcements from China Listed Companies spanning the period of 2015 to 2017. The results show that the average cumulative abnormal return after the rumor event is significantly positive in the positive rumor sample and neutral sample, and significantly negative in the negative rumor sample. After the clarification announcements, we find the announcements effective for the positive and neutral rumor sample, but not in the case of the negative sample. However, by comparing different clarification times of each sample, we find that the earlier the clarification time is, the smaller the impact on the companies in positive and negative rumor examples.

Résumé :

Climate variability during the Holocene (the last 11700 calendar yr b2k) is relatively subtle whether compared with the higher amplitude characterizing the last glacial period. Nonetheless, several proxy data (e.g. pollen, plant macrofossils, glacier length variations), indicate detectable changes in temperature and/or moisture during this period. Retreating glaciers may uncover peat sequences that were once ice-buried. Palynological analysis of those organic deposits provides information on plant communities colonization in proglacial areas as well as long-distance vegetations signal. The aim of this study is to investigate the potential of high-altitude pollen records for vegetation history and climate reconstruction during the Holocene in the south-western Italian Alps. The study sites are located in the Rutor Glacier area (La Thuile Valley). Within this thesis, modern (a) and past (b) vegetation and climate conditions have been analyzed using different methodologies; a) Modern pollen rain, vegetation, climate and terrain parameters have been collected at 27 sampling sites placed along an altitudinal gradient from the village of Morgex (983 m asl) to the Rutor Glacier forefield (2668 m asl). This altitudinal training set has been designed (i) to provide a robust modern reference for reliable palaeoenvironmental and quantitative interpretations of past changes in vegetation composition; (ii) to integrate the newly-obtained pollen spectra into a large, continental dataset of modern pollen samples (EMPD - European Modern Pollen Database) for quantitative climate reconstructions. b) New paleoecological, stratigraphical and geochronological data have been obtained from peat deposits (Lac dans la Roche peat bog, 2594 m asl) and integrated with the well-known buried peat sequences exposed at 2510 m asl by the '80es Rutor Glacier retreat. The result is a composite paleoecological record covering most of the Holocene. At the base of the composite sequence, meltwater glacier sediments testify to the early Holocene development of a proglacial lake, before Abies alba expansion in the western Italian Alps. These sediments bear the palynological evidence of a primary plant succession testifying to an ecological mechanism of colonization on deglaciated terrains. Moreover, macrofossil analysis highlighted the local presence of alpine dwarf - shrubland species (e.g. Salix cfr. foetida). Pinus cembra occurs rather densely in the alpine belt from ca. 8000 yrs cal. BP, representing the beginning of the Holocene thermal maximum in the high Alps. Between 8000 - 4000 yrs cal. BP timberline was higher than today. A radiocarbon age obtained from a Pinus cembra wood fragment suggests the occurrence of pines as high as ca. 2600 m asl at around 5650 yrs cal BP. The dated wood fragment cannot have been long-distance transported, thus it indicates the presence of this species in situ. Moreover, paleobotanical insights and comparison with climate threshold of modern treeline (ca. 9,3° C at 2400 m asl), suggest a positive treeline shift of almost 150 m. Preliminary pollen-inferred Tjul reconstructions show higher values (up to 2 - 3°C) than today for this interval. At around 4000 yrs cal. BP Picea abies and Alnus viridis started to expand. A progressive natural/climatic driven decline of Pinus cembra took place. Pollen inferred Tjul shows a decreasing trend between 2900 – 2000 yrs cal BP and possibly a short-lived cold event starting at ca. 1140 yrs cal. BP, pre-dating the onset of the LIA (Little Ice Age). A subsequent arolla pine forests reduction can be attributed to LIA glacier advance (max occurred between 1751 – 1864 AD), which is testified in the upper part of the sequence by fluvioglacial deposits.

Résumé :

During the startup phase of a production process while statistics on the product quality are being collected it is useful to establish that the process is under control. Small samples ni qi=1 are taken periodically for q periods. We shall assume each measurement is multivariate. A process is under control or on-target if all the observations are deemed to be independent and identically distributed. Let Fi represent the empirical distribution function of the ith sample. Let F¯ represent the empirical distribution function of all observations. Following Lehmann (1951) we propose statistics of the form i=1q -infinityinfinityFi s-F- s2d Fs. The asymptotics of nonparametric q-sample Cramer-Von Mises statistics were studied in Kiefer (1959). The emphasis there, however, is on the case where n(i) → infinity while q stayed fixed. Here we study the asymptotics of a family of randomness statistics, that includes the above. These asymptotics are in the quality control situation (i.e q → infinity while n( i) stay fixed). Such statistics can be used in many situations; in fact one can use randomness statistics in any situation where the problem amounts to a test of homoscedasticity or homogeneity of a collection of observations. We give two such applications. First we show how such statistics can be used in nonparametric regression. Second we illustrate the application to retrospective quality control.

El esparcimiento de rumores es un modelo intuitivo para la difusión de información en una red social. Una entidad que controla la red, por ejemplo el proveedor del servicio, desea acelerar el proceso de esparcimiento del rumor, de forma tal que se maximice la cantidad de información entregada. Este problema, definido a grandes rasgos, ha sido objeto de múltiples investigaciones en el último tiempo, entre otros como marketing viral y maximización de influencia. Un enfoque natural y ausente en los estudios previos es la adaptividad. En este trabajo se abordan las siguientes preguntas: ¿cómo el controlador puede usar la información del estado de la red para acelerar el proceso de rumor? y ¿cuánto beneficio se obtiene de tal conocimiento? Un concepto novedoso es la comunicación oportunista en redes; cada agente de la red social comparte información (noticias, actualización de software, etc.) con otros usuarios al momento de estar momentáneamente en rango (vía wi-fi, bluetooth, etc.), de esta forma se evita la saturación de la infraestructura que soporta la red. Con esta motivación se estudia un modelo a tiempo continuo, donde cada par de nodos se comunica de acuerdo a un proceso de Poisson de cierta tasa y el rumor se transmite siempre que alguno estuviera informado. Las anteriores comunicaciones no tienen costo para el controlador, pero si éste lo desea puede informar a cualquier nodo pagando un costo unitario por ello. En vez de la usual restricción de presupuesto se fija un deadline, en tal tiempo todos los nodos deben estar informados, debiendo pagar el controlador un costo unitario por cada nodo que no haya obtenido el rumor antes del deadline. Una estrategia no-adaptativa puede informar sólo al comienzo del periodo y cuando se cumple el deadline, pagando por todos aquellos nodos que no se comunicaron nunca con otro nodo informado. Una estrategia adaptativa puede intervenir la red en cualquier instante, usando toda la información disponible hasta ese entonces, en particular sabiendo cuales nodos tienen el rumor en cada momento. El resultado principal de este trabajo es que en el caso homogéneo, donde cada par de nodos se encuentra con la misma tasa, el beneficio de la adaptividad está acotado por una constante. La demostración requiere un entendimiento profundo del proceso estocástico que domina el sistema, que se cree ya una contribución interesante. Adicionalmente, se presenta una extensión natural del caso homogéneo, donde el controlador está interesado sólo en un conjunto de nodos y no en toda la red social, se demuestra que en este escenario el beneficio de la adaptividad también está acotado por una constante. Finalmente, se muestra que, sin el supuesto de homogeneidad, el beneficio de la adaptividad puede crecer de forma no acotada.

Résumé :

Nel caso d'Orleans come in quello di Catania non si segnala alcuna misteriosa sparizione, i fatti non sono realmente accaduti: il rumor crea l'evento. Come in un sogno in cui fantasia e realta' si confondono, la memoria collettiva si appropria del mito fluttuante, lo ancora alla realta', e di quello si serve per gridare a gran voce il proprio turbamento e le proprie contraddizioni. Tutto cio' allora sembra essere prova del fatto che quelle contraddizioni e quei turbamenti in realta' non abbandonano mai il corpo sociale ma da questo vengono riprese ed esternate quando una lettura del contesto da parte degli attori viene interpretata come sovraccarico d'ambivalenza. E' chiaro che espressa in questi termini la lettura contestuale non sara' mai espressione di una crisi oggettiva: due citta', contesti differenti, contraddizioni differenti. Ma la questione nodale sembra essere un'altra. Due citta' con contesti e contraddizioni differenti alle spalle, in tempi lontani l'una dall'altra adottano lo stesso modo di procedere: una forza mitopoietica accomuna le due citta'. Se dunque la lettura e la conseguente interpretazione del contesto sono lasciate agli attori e trovano senso se inserite in quel contesto, il ricorso a spiegazioni dal carattere mitologico e la ricerca di colpevoli potrebbero invece accomunare l'intera societa'.
In the case of Orleans as in Catania, no mysterious disappearance has been reported, the facts did not really happen: the rumor creates the event. As in a dream in which fantasy and reality mingle, the collective memory takes possession of the floating myth anchoring it to reality using it to shout loudly its own disturbance and contradictions. Then everything seems to be evidence that those contradictions and disturbances actually never leave the social body but these are recovered and expressed when a reading of the context by the actors is interpreted as overload of ambivalence. It is clear that the contextual reading expressed in these terms will never be expression of an "objective" crisis: two cities, different environments, different contradictions. But the crucial issue seems to be different. Two cities with different contexts and contradictions behind, in distant times one to the other, take the same approach: a mythopoeic force unites the two cities. If the reading of the context and its interpretation is left to the actors and finds direction when put in that context, then the use of mythological explanations and the search for culprits could unite the entire society.

Résumé :

This thesis discusses limit cycles and behavior of rumor models. The first part presents the deterministic Daley-Kendall model (DK) with arrivals and departures and comparison of the Susceptibles, Infectives and Removed (SIR) model and the DK model. The second result is a part of the qualitative analysis and the general behavior of extension of the Daley-Kendall model. Here we discuss how the halting rate of spreaders causes the model to change from a stable equilibrium or a stable limit cycle. In the third part we carry out model validation and use both synthetic data and real data sets and fit them to the numerical solutions of the extended Daley-Kendall model. Finally, we find the parameter estimates and standard errors. In this way we shall be able to decide whether the numerical solutions quantifying the relationships between the variables obtained from the qualitative analysis can be accepted as the best description of the data. We discuss sensitivity analysis results and traditional sensitivity functions.

Résumé :

During the 12th to the 16th century the Scandinavian region went through a cultural change, from Germanic to Latin culture. This change effected a wide variety of areas for example law, piety, clothing, religion and system of writing. It is the change in the system of writing this essay will examine i.e. the change from runes to the Latin alphabet. The medieval runic Europe (including the Nordic countries and the north Atlantic islands) has a great variety in their numbers of runic material but in total there is about 2800 of them. Most are from the Scandinavian countries Sweden and Norway. The runic alphabet and the Latin alphabet coexisted during the Nordic Middle ages but the Latin alphabet became dominant over time.The runic alphabet changed during the 11th and 12th centuries from 16 runes to 28 (as many letters as the Latin alphabet) and was in continues use during the whole time period. The question is why it survived for so long? How come the runic alphabet did not die out sooner given the introduction of the Latin alphabet and the influence from Latin countries (i.e. Western Europe)? Earlier research has largely focused on the Viking age carvings and has not problematized the change from an historical point of view or from a cultural perspective. This essays goal is to explain that change by categorizing the inscriptions according to their theme and content in order to identify runic usage as a cultural belonging, be it a passive or active choice. I will also discuss the literacy level (or to be precis the runeliteracy) of the Scandinavian countries. Who could read the runes and in what context where they used?

Résumé :

Cette thèse porte sur l'endiguement des rumeurs et la minimisation de l'influence dans les réseaux sociaux. Dans la première partie, nous formalisons deux problèmes distincts de minimisation d'influence sous le modèle à LTM, c'est-à-dire la minimisation des pertes avec perturbation (LMD) et la minimisation de la diffusion avec cible garantie (DMGT). Pour le problème LMD, nous montrons qu'il est équivalent à la résolution d'un problème de programmation linéaire en nombres entiers. Pour le problème DMGT, nous fournissons une technique pour rechercher une solution optimale qui fonctionne pour les cas particuliers et discutons d'une heuristique simple pour trouver une solution dans le cas général. La maîtrise des rumeurs est analysée dans les deuxième et troisième parties de cette thèse en adoptant différentes stratégies de contrôle des rumeurs. Nous adoptons d'abord la stratégie du contrepoids en diffusant une information correcte. Nous proposons une version compétitive et généralisée, c'est-à-dire LT1DT. Le problème de la minimisation de la propagation des rumeurs (MRS) est abordé et s'est avéré difficile pour notre modèle généralisé. En raison de la dureté théorique du problème MRS, nous présentons trois heuristiques différentes et définissons leurs versions contraintes pour souligner l’effet de proximité pour résoudre le problème MRS. Pour contrôler la propagation de la rumeur, nous considérons ensuite la stratégie de perturbation du réseau en bloquant un ensemble de noeuds. Nous proposons ensuite une formulation non linéaire du problème d'identification des top-k-bloquants et introduisons quelques techniques mathématiques pour linéariser la formulation non linéaire
This thesis mainly focuses on the rumor containment and influence minimization problems in social networks. In the first part, we formalize two different influence minimization problems generalizing the scenarios under the LTM model, i.e., the Loss Minimization with Disruption (LMD) and the Diffusion Minimization with Guaranteed Target (DMGT). For the LMD problem, we show that it is equivalent to solving an integer linear programming problem. For the DMGT problem, we provide a technique to search for an optimal solution that works in some particular cases and discuss a simple heuristic to find a solution in the general case.Rumor containment is analyzed in the second and third parts of this thesis by investigating different rumor control strategies. We first adopt the counterbalance strategy by spreading truth. We propose a competitive and generalized version of the LTM, i.e., LT1DT. The problem of minimizing rumor spread (MRS) is addressed. To cope with the computational complexity of the MRS problem, we present three different heuristics and define their constrained versions to highlight the proximity effect for solving the MRS problem. To control the rumor spread, we then consider the network disruption strategy by blocking a set of nodes. We then propose a non-linear formulation of the top-k blockers identification problem in the LTM based on the notion of cohesiveness and introduce some mathematical techniques to linearize the non-linear formulation. The complexity of the integer linear programming can be further reduced by showing that given a seed set, the evolution process in the whole network is equivalent to that in its active sub-network

Résumé :

AbstractAt present most alpine glaciers are not in equilibrium with the current climate, as a result they are undergoing a dramatic mass loss. Monitoring glacial variations is crucial to assess the consequences of climate change on the territory. In this work different geomatics techniques are exploited to measure and monitor the Rutor glacier over the years. In this study two different techniques were adopted to generate 3 digital surface models (DSMs): aerial and satellite photogrammetry. Two photogrammetric aerial surveys were carried out: at the end of the hydrological year 2019/20 and at the end of the following hydrological year. Additionally, a very high-resolution satellite stereo pair, acquired by the Pléiades-1A platform in 2017, was processed to assess whether satellite images can be applied to extract the 3D surface of the Rutor glacier. In order to evaluate the Rutor glacier mass-balance throughout the years several reference points were positioned and measured before the 2021 aerial flight. Thanks to the presence of the materialized points the 2021 model is considered as the ‘Reference Model’ against which subsequent models can be compared for glacier analysis. This model was validated by means of a comparison with the authoritative Regional DSM based on LiDAR surveys. In alpine glaciers, the positioning of artificial square cross target in time invariant areas is crucial to enable a multitemporal 4D analysis. The use of very high-resolution satellite imagery allows large areas to be mapped in 3D, but with lower accuracies proportionally decreasing with respect to slope and exposure.

Résumé :

The rumor detection problem on social networks has attracted considerable attention in recent years with the rise of concerns about fake news and disinformation. Most previous works focused on detecting rumors by individual messages, classifying whether a post or blog entry is considered a rumor or not. This paper proposes a method for rumor detection on topic-level that identifies whether a social topic related to a scientific topic is a rumor. We propose the use of a topic model method on social and scientific domains and correlate the topics found to detect the most prone to be rumors. Results applied in the Zika epidemic scenario show evidence that the least correlated topics contain a mix of rumors and local community discussions.

Résumé :

Rumor spreaders are increasingly taking advantage of multimedia content to attract and mislead news consumers on social media. Although recent multimedia rumor detection models have exploited both textual and visual features for classification, they do not integrate the social structure features simultaneously, which have shown promising performance for rumor identification. It is challenging to combine the heterogeneous multi-modal data in consideration of their complex relationships. In this work, we propose a novel Multi-modal Feature-enhanced Attention Networks (MFAN) for rumor detection, which makes the first attempt to integrate textual, visual, and social graph features in one unified framework. Specifically, it considers both the complement and alignment relationships between different modalities to achieve better fusion. Moreover, it takes into account the incomplete links in the social network data due to data collection constraints and proposes to infer hidden links to learn better social graph features. The experimental results show that MFAN can detect rumors effectively and outperform state-of-the-art methods.

Résumé :

Measurements of NOx and CO in methane-fired, lean-premixed, high-pressure jet-stirred reactors (HP-JSRs) independently obtained by Rutar [1] and Rutar et al. [2] and by Bengtsson [3] and Bengtsson et al. [4] are well predicted assuming simple chemical reactor models and the GRI 3.0 chemical kinetic mechanism. The single-jet HP-JSR of Rutar [1] and Rutar et al. [2] is well modeled for NOx and CO assuming a single PSR for Damköhler number below 0.15. Under these conditions, the estimates of flame thickness indicate the flame zone, that is, the region of rapid oxidation and large concentrations of free radicals, fully fills the HP-JSR. For Damköhler number above 0.15, that is, for longer residence times, the NOx and CO are well modeled assuming two PSRs in series, representing a small flame zone followed by a large post-flame zone. The multi-jet reactor of Bengtsson [3] and Bengtsson et al. [4] is well modeled assuming a large PSR (over 88% of the reactor volume) followed by a short PFR, which accounts for the exit region of the HP-JSR and the short section of exhaust prior to the sampling point. The Damköhler number is estimated between 0.01 and 0.03. Our modeling shows the NOx formation pathway contributions. Although all pathways, including Zeldovich (under the influence of super-equilibrium O-atom), nitrous oxide, Fenimore prompt, and NNH, contribute to the total NOx predicted, of special note are the following findings: 1) NOx formed by the nitrous oxide pathway is significant throughout the conditions studied; and 2) NOx formed by the Fenimore prompt pathway is significant when the fuel-air equivalence ratio is greater than about 0.7 (as might occur in a piloted lean-premixed combustor) or when the residence time of the flame zone is very short. The latter effect is a consequence of the short lifetime of the CH radical in flames.
