Coordination Incentives in Cross-Border Macroprudential Regulation  [PDF]
Alexis Derviz, Jakub Seidler
Modern Economy (ME) , 2014, DOI: 10.4236/me.2014.511098

When national financial sector regulators need to mutually harmonize macroprudential policy decisions, imperfections of cross-border information exchange may undermine fair cooperation. Attempts to overcome the effects of informational distortions by delegating macroprudential policy to a supranational body are also likely to entail welfare losses. We study the tradeoff between macroprudential policy autonomy and centralization by means of a signaling game of imperfect information played by two national regulators. The model concentrates on informational frictions in an environment with otherwise fully aligned preferences. We show that even in the absence of evident conflicting goals, the non-transferable nature of some regulatory information creates misreporting incentives. Reporting accuracy is a part of a broader problem of strategic advantage-seeking by the national regulators. Therefore, cross-border coordination mechanisms, centralized or not, that limit strategic behavior are preferable to those allowing its full deployment. The results are applicable to systemic risk management by international organizations, including the relevant EU institutions.

The Impact of Residential and Non-Residential Demand on Location-Allocation Decision-Making: A Case Study of Modelling Suitable Locations for EMS in Leicester and Leicestershire, England UK  [PDF]
Emeka Chukwusa, Alexis Comber
Journal of Geographic Information System (JGIS) , 2018, DOI: 10.4236/jgis.2018.104020
Abstract: The research examines the impact of residential and non-residential demand on facility location planning by comparing results from two location models: travel-to-work (TTW) and Residential model. The TTW model considers short-term changes in the state of the population due to travel-to-work (non-residential demand). By contrast, the Residential model uses a static snap-shot of the population based on official census estimates (residential demand). Comparison of both models was based on a case study of Emergency Medical Services (EMS) location-allocation planning problem in Leicester and Leicestershire, England, UK. Results showed that the using a static residential demand surface to plan EMS locations overestimates actual demand coverage, compared to a non-residential demand surface. Differences in location-allocation results between the models underscore the importance of accounting for temporal changes in the state of the population when planning locations for health service facilities. The findings of the study have implications for siting of EMS, designing, and planning of EMS service catchments and allocation of prospective demand to EMS sites. The study concludes that consideration of temporal changes in the state of the population is important for reliable and efficient location-allocation planning.

The entropy of a mixture of probability distributions
Alexis Vos
Entropy , 2005, DOI: 10.3390/e7010015
Abstract: If a message can have n different values and all values are equally probable, then the entropy of the message is log(n). In the present paper, we investigate the expectation value of the entropy, for arbitrary probability distribution. For that purpose, we apply mixed probability distributions. The mixing distribution is represented by a point on an infinite dimensional hypersphere in Hilbert space. During an `arbitrary' calculation, this mixing distribution has the tendency to become uniform over a flat probability space of ever decreasing dimensionality. Once such smeared-out mixing distribution is established, subsequent computing steps introduce an entropy loss expected to equal $\\frac{1}{m+1} + \\frac{1}{m+2} + ... + \\frac{1}{n}$, where n is the number of possible inputs and m the number of possible outcomes of the computation.
El papel de la universidad en la conformación de un modelo productivo sustentable en Venezuela
Cuadernos del Cendes , 2005,
Abstract: shaping a sustainable production model poses significant challenges to academic institutions. the new technological and economic paradigm demands socio-institutional efforts to address new forms of knowledge production. the evolution towards eco-efficient production is perceived as a learning process that goes beyond the assimilation and use of new technologies, bringing up shifts in the paradigm, from a technological and economic perspective to an environmental-productive one. such a process takes very different forms in the global framework. this article highlights some trends in the production of scientific and technological knowledge in the environmental-industrial field, the nature of the demands of that knowledge in venezuela, and how the universidad central de venezuela deals with them.
Literatura periódica
Olivar , 2008,
Abstract: the newspaper column produced by writers is the result of a long tradition of symbiosis between the writer and the press in spain, though it is not always seen as a literary genre, which it nevertheless is in the majority of cases and in accordance with all the main definitions of literature.
Revista chilena de literatura , 2007, DOI: 10.4067/S0718-22952007000100003
Abstract: the author of this article proposes an analysis, an interpretation, and a reordering of jorge teillier?s poetics, focusing on the interest in the re-elaboration of the myth of the lost paradise present in his lyrical creations, our source of information being the totality of the author?s published works. the analysis intends to show that far from the traditional views on teillier?s art centered on the poems of his homeland, the search for a lost paradise represents the keystone of his poetical work
La estructura productiva de América Latina: convergencia hacia la sociedad del conocimiento
Revista Venezolana de Economía y Ciencias Sociales , 2005,
Abstract: to a great extent, the discourse over the knowledge society assumes that it is simply at the service of production and consumption and this simplified version of reality is radically modifying the behavior and organization of the structures that generate knowledge, with an evident impact on the economy and production in the developed countries of the north. these economies effectively produce added value based on the incorporation of knowledge but the natural re-sources they consume come largely from the south. as the latter contribute basically natural resources to the world economy, then the incorporation of knowledge does not have the same implications as in the north, so that the universal applicability of the "productive paradigm in the knowledge society" is questionable. nevertheless, latin america is adopting the new forms of generating knowledge defined in the north, redefining the relationship between higher education and society, privileging links to the productive process, without taking these differences into account. at the same time, there is a lamentable failure to strengthen key sectors such as the basic sciences and engineering, with serious implications for the potential promotion of growth and well-being.
La repetición del gesto en el discurso interactivo
Revista signos , 2004, DOI: 10.4067/S0718-09342004005500004
Abstract: this article is about the use of spontaneous gestures in interaction and, more precisely, about the repetition of the interlocutor's gestures. the analysis of four instances of gesture repetition found in two dyadic discussions with spanish native speakers shows that this discursive activity operates in a way similar to verbal repetition. that is, the recipient can simply reproduce the interlocutor's gesture (retake) or recycle it by introducing various modifications (reformulation). all four instances of gesture repetition studied were performed by the same participant, who behaved almost like an interviewer with her partners. gesture repetition played a part in facilitating the partners' speech in two areas: the negotiation of meaning (ideational dimension of language), and the conduct of interaction (discursive dimension of language). more importantly, gesture repetition is an indicator that speakers pay attention to the interlocutors' gestures, confirming the communicative purpose of gesture.
Approved Beta Interferons in Relapsing-Remitting Multiple Sclerosis: is there a one odd out?
Alexis Clapin
Journal of Central Nervous System Disease , 2012, DOI: 10.4137/JCNSD.S10150
Abstract: Three interferons are marketed for the treatment of relapsing-remitting multiple sclerosis. In its pivotal trial, one of them demonstrated impressive efficacy as a once-weekly regimen, but later head-to-head studies and reviews questioned its superiority. Analysis of this pivotal trial in publications and health authority reviews has shown that its early termination might have caused attrition bias. Censored patients were different from those completing the study on magnetic resonance imaging parameters and benefited from placebo in terms of relapse rate. Early progression of disability and differences in follow-up duration could have favored the benefit observed for the progression of disability outcome. Only the raw data could be of help to confirm or refute doubts about this trial. Raw data should be made available to the scientific community.
