Consumer confidence: Causality links with subjective and objective information sources
2020
Abstract This study analyses the relationship of causality between consumer confidence and the economic information ecosystem from subjective (i.e., business sentiment) and objective sources (financial information from listed companies and the stock index). Our sample covers Spain from June 2011 to December 2018. Our results show that consumer confidence and economic information can exert a causality influence on each other. The results show Granger causality from IBEX35 and total assets in the financial sector and leverage of the companies in the energy sector to the consumer confidence index (CCI), in the first lag: from operating income in the telecommunications sector to the CCI in the …
Bank-specific shocks and aggregate leverage: Empirical evidence from a panel of developed countries
2020
International audience; This paper investigates the link between shocks in the banking sector and aggregate leverage measured by the credit-to-GDP gap. Using a balanced panel of 15 countries for the period 1989–2016, we exploit the approach due to Gabaix (2011) and consider banking granular shocks as an indicator of banking distress. Using methods that account for potential endogeneity, we find that banking shocks Granger-cause aggregate leverage. In particular, banking shocks tend to increase the level of leverage and cause departures of the credit-to-GDP ratio from its long-term trend.
Host-manipulation by parasites with complex life cycles: adaptive or not?
2010
7 pages; International audience; The effect of host manipulation by parasites on trophic transmission to final hosts remains unclear. The transmission benefits gained by manipulative parasites are difficult to assess, and evidence for a causal link between manipulation and trophic transmission is missing. In addition, infected intermediate hosts can also be more vulnerable to predation by nonhosts, whereas recent theoretical advances indicate that the evolution of host manipulation does not require increased specificity in trophic transmission. We propose that a deeper consideration of the evolution of complex life cycles in helminth parasites might provide a different perspective on the ev…
Selectivity in Probabilistic Causality: Where Psychology Runs Into Quantum Physics
2011
Given a set of several inputs into a system (e.g., independent variables characterizing stimuli) and a set of several stochastically non-independent outputs (e.g., random variables describing different aspects of responses), how can one determine, for each of the outputs, which of the inputs it is influenced by? The problem has applications ranging from modeling pairwise comparisons to reconstructing mental processing architectures to conjoint testing. A necessary and sufficient condition for a given pattern of selective influences is provided by the Joint Distribution Criterion, according to which the problem of "what influences what" is equivalent to that of the existence of a joint distr…
Linguaggio Tempo Narrazione
2009
La natura del segno linguistico è esaminata attraverso le nozioni matematiche di linearità e non-linearità. The paper aims to explain two distinct but related aspects of the linguistic sign. That is to say: linearity and non-linearity. In order to satisfy this theoretical purpose, we will seek to analyze the conceptual background of saussurean linguistics in the light of some insights of the so-called emergentist epistemologies. As we will show, the concept of downward causation play a pivotal role in such a theoretical framework.
Grandmother cells: much ado about nothing
2016
International audience; We do not dispute the possibility of the existence in the brain of “grandmother cells”, which are very finely tuned neurons that fire only in the presence of specific objects or categories. However, we question the causal efficacy of such neurons at the functional or behaviour level. We claim that, even though very familiar items, such as “my grandmother”, may well have associated grandmother neurons, these neurons have very little, or no impact on the actual recognition of my grandmother. A study by Thomas, Van Hulle, and Vogels [(2002). Encoding of categories by noncategory-specific neurons in the inferior temporal cortex. Journal of Cognitive Neuroscience, 13, 190…
Loss of intersective gradience as the lifeboat of a dying construction. An analysis of the diachronic change of causative bring
2021
Abstract This paper focusses on diachronic processes which lead to the disambiguation between different constructions involving the same verb. It follows the development of bring as a periphrastic causative over the course of the Early Modern and Late Modern English periods and compares it to the development of other bring constructions. In a corpus-based analysis, it utilizes measures of cue strength as well as collostructional analysis to determine whether reflexive objects, negation, modals or the passive are cues strongly associated with the dying periphrastic causative X bring cause Y to-inf. Results indicate that the construction indeed increasingly attracts reflexive objects in combi…
Problems with primary vs. secondary grammaticalization: the case of East and mainland Southeast Asian languages
2015
Abstract The present paper aims at testing four criteria for the distinction between primary vs. secondary grammaticalization in East and mainland Southeast Asian languages. These languages are of special interest for research on grammaticalization because they show limitations in the coevolution of meaning and form and because pragmatic inference is very prominent (lack of obligatory grammatical markers, multifunctionality). If the four criteria work in these languages, this can be taken as a good indicator for their cross-linguistic, maybe universal relevance. The criteria are tested with three markers that stand for three different types of multifunctionality: (i) the Khmer verb baːn ‘co…
Aspectes de la transitivitat en els inicis del català modern
2019
En aquest estudi de corpus hem volgut fer una primera aproximació a diversos aspectes de la transitivitat, entesa com a fenomen amb diversos vessants, en els textos corresponents a l’inici del català modern (segle XVII, amb un èmfasi especial en la primera meitat de segle). Hem tractat, concretament, el cas de diversos verbs que presenten un comportament vacil·lant entre l’ús transitiu i l’ús intransitiu, i ens hem acostat a aquest fenomen des del vessant del marcatge diferencial d’objecte, atès que aquest règim vacil·lant és un factor que pot crear confusió a l’hora d’analitzar l’extensió dels objectes directes introduïts per a (v. § 2). A continuació, i encara mantenint el marcatge difere…
