Financial contagion through space-time point processes
2020
AbstractWe propose to study the dynamics of financial contagion by means of a class of point process models employed in the modeling of seismic contagion. The proposal extends network models, recently introduced to model financial contagion, in a space-time point process perspective. The extension helps to improve the assessment of credit risk of an institution, taking into account contagion spillover effects.
Metabolic detoxification: implications for thresholds.
2000
The fact that chemical carcinogenesis involves single, isolated, essentially irreversible molecular events as discrete steps, several of which must occur in a row to finally culminate in the development of a malignancy, rather suggests that an absolute threshold for chemical carcinogens may not exist. However, practical thresholds may exist due to saturable pathways involved in the metabolic processing, especially in the metabolic inactivation, of such compounds. An important example for such a pathway is the enzymatic hydrolysis of epoxides via epoxide hydrolases, a group of enzymes for which the catalytic mechanism has recently been established. These enzymes convert their substrates via…
Le déploiement d'un pilotage stratégique des coûts dans les services informatiques de deux groupes internationaux : perspective instrumentale et anal…
2011
This article analyses the strategic cost management stream with an instrumental point of view and two case studies. We try to show in what extend the Activity-based Costing developments could be included in a strategic approach of the management accounting and to test if the ABC is a relevant tool to drive the strategy. The first part synthesizes the strategic cost management developments which try to improve the Activity-based Costing method. In the first part, we describe them using the Strategic Management Accounting stream, with a link with cost management and ABC. The second part exposes a taxonomy of the reasons why using the ABC method. In a third part, we confront our developments t…
Introduction: Europe, Heritage and Memory—Dissonant Encounters and Explorations
2019
AbstractThe introduction to Dissonant Heritages and Memories in Contemporary Europe theoretically grounds the book’s various problematizations of heritage and identity struggles in Europe today, including the heritage policies of the EU and other intergovernmental organizations, struggles over ethnographic and historical exhibitions, activist practices, and dissonant memories. By discussing these struggles and their problematizations, the introduction connects the book to a wide range of ongoing debates across the humanities and social sciences. At the same time, it discusses how convergences and divergences within and between the volume’s chapters foster new insights regarding the concepts…
Cell state prediction through distributed estimation of transmit power
2019
Determining the state of each cell, for instance, cell outages, in a densely deployed cellular network is a difficult problem. Several prior studies have used minimization of drive test (MDT) reports to detect cell outages. In this paper, we propose a two step process. First, using the MDT reports, we estimate the serving base station’s transmit power for each user. Second, we learn summary statistics of estimated transmit power for various networks states and use these to classify the network state on test data. Our approach is able to achieve an accuracy of 96% on an NS-3 simulation dataset. Decision tree, random forest and SVM classifiers were able to achieve a classification accuracy of…
Validity and fairness of a new entry diagnostics test in higher education economics
2020
Abstract Research has been focusing increasingly on measuring students’ prior economic knowledge in higher education. However, in German-speaking countries, valid instruments are rare. A diagnostic study investigated the validity and fairness of an internationally established economic knowledge test (adapted German version of TUCE IV and TEL IV) with a representative sample of 7664 students from 46 universities across Germany. Previous findings with the dataset ( Zlatkin-Troitschanskaia et al., 2019a ) suggest that native language significantly predicts missing answers in the knowledge test. Similar effects can be found for gender. After coding missing answers as incorrect, students with a …
Understanding the Influence of Eating Patterns on Binge Drinking: A Mediation Model
2020
Background: Binge drinking is an important health problem, and it has been related to binge eating and fat intake in animal models, but this relationship has not been tested in humans. The first objective of this study was to analyze whether binge eating and fat intake are related to binge drinking in a youth sample. The second objective was to analyze whether binge eating and fat intake mediate the relationship between individual factors associated with binge eating and fat intake (sex, body mass index (BMI), drive for thinness, body dissatisfaction, eating styles, impulsivity, and food addiction) and binge drinking. Methods: A sample of 428 undergraduate students filled out several questi…

Ficciones inmunitarias. Sobre la lógica de la inmunidad en la cultura contemporánea
2018
This article develops the concept of “immunitarian fiction” taking as paradigmatic examples epidemics and zombie narratives, which share the idea of contagion as the main matrix of their narrative. The article tries to address the following question: in what way do these fictions, and other similar ones, participate in the imaginary of immunity and, at the same time, show some of their internal contradictions? For this, the text reflects on a set of cultural products of mass diffusion (novels, television series, cinematographic works). We analyze, in the first place, how these fictions highlight the fears and social anxieties linked to the tensions of the “immune paradigm” and represent the…
Early warning of systemic risk in global banking: eigen-pair R number for financial contagion and market price-based methods
2021
AbstractWe analyse systemic risk in the core global banking system using a new network-based spectral eigen-pair method, which treats network failure as a dynamical system stability problem. This is compared with market price-based Systemic Risk Indexes (SRIs), viz. Marginal Expected Shortfall (MES), Delta Conditional Value-at-Risk (Delta-CoVaR), and Conditional Capital Shortfall Measure of Systemic Risk (SRISK) in a cross-border setting. Unlike paradoxical market price based risk measures, which underestimate risk during periods of asset price booms, the eigen-pair method based on bilateral balance sheet data gives early-warning of instability in terms of the tipping point that is analogou…
