Measuring frequency domain granger causality for multiple blocks of interacting time series
2011
In the past years, several frequency-domain causality measures based on vector autoregressive time series modeling have been suggested to assess directional connectivity in neural systems. The most followed approaches are based on representing the considered set of multiple time series as a realization of two or three vector-valued processes, yielding the so-called Geweke linear feedback measures, or as a realization of multiple scalar-valued processes, yielding popular measures like the directed coherence (DC) and the partial DC (PDC). In the present study, these two approaches are unified and generalized by proposing novel frequency-domain causality measures which extend the existing meas…
The Perception of Causality in Light of Process Ontology
2015
Human perception has an important emotional dimension. Besides having a “presentational” element that dominates the high cognitive activities of human beings, there are certain “densities of feelings,” which are inextricably intertwined with the presentational contents of our perceptual states. This does not mean that human perception is just instinctive, irrational, or intrinsically subjective. The Whiteheadian scheme allows us to determine the nature of the “emotional background” of perception without falling into the traps of subjectivism, representationalism, or substantialism. The feeling which I call “the sense of physicality” is just one of the elements of this emotional dimension in…
Granger Causality Analysis of Transient Calcium Dynamics in the Honey Bee Antennal Lobe Network
2023
Odorant processing presents multiple parallels across animal species, and insects became relevant models for the study of olfactory coding because of the tractability of the underlying neural circuits. Within the insect brain, odorants are received by olfactory sensory neurons and processed by the antennal lobe network. Such a network comprises multiple nodes, named glomeruli, that receive sensory information and are interconnected by local interneurons participating in shaping the neural representation of an odorant. The study of functional connectivity between the nodes of a sensory network in vivo is a challenging task that requires simultaneous recording from multiple nodes at high temp…
Information Decomposition in Bivariate Systems: Theory and Application to Cardiorespiratory Dynamics
2015
In the framework of information dynamics, the temporal evolution of coupled systems can be studied by decomposing the predictive information about an assigned target system into amounts quantifying the information stored inside the system and the information transferred to it. While information storage and transfer are computed through the known self-entropy (SE) and transfer entropy (TE), an alternative decomposition evidences the so-called cross entropy (CE) and conditional SE (cSE), quantifying the cross information and internal information of the target system, respectively. This study presents a thorough evaluation of SE, TE, CE and cSE as quantities related to the causal statistical s…
Denboratik kausara: -nez gero kausazko lokailuaren garapenaz
2019
LABURPENA Lan honetan -nez gero atzizki multzoaren garapena dugu aztergai, lehen testuetatik hasi eta gaurdaino. Denbora lokailuetatik sortu diren beste kausazko lokailu asko bezala, -nez gero batez ere mintza-ekintzak eta antzekoak justifikatzeko erabiltzen da. Hala ere, kausa neutroagoak adierazteko ere erabiltzen da. Gaztelaniaz ez bezala, menpeko perpausaren kokagunea ez da aldatu azken mendeotan eta funtzio informatiboan ere ez dugu aldakuntza handirik ikusten. Sumatzen dugun garapen nagusia da beharbada edukizko kausazko neutroetan maizago erabiltzeko joera. Oro har, -nez gero kausazko menderagailuak, gazt. ya que-rekin baino, antz handiagoa du fr. puisque eta ing. since lokailuekin. …
Nonlocal field correlations and dynamical Casimir-Polder forces between one excited- and two ground-state atoms
2006
The problem of nonlocality in the dynamical three-body Casimir-Polder interaction between an initially excited and two ground-state atoms is considered. It is shown that the nonlocal spatial correlations of the field emitted by the excited atom during the initial part of its spontaneous decay may become manifest in the three-body interaction. The observability of this new phenomenon is discussed.
Parents' causal attributions concerning their children's academic achievement
2007
Katja Natale seurasi väitöstutkimuksessaan vanhempien lastensa koulumenestystä koskevien kausaaliattribuutioiden eli syyselitysten muotoutumista lasten siirtyessä esikoulusta kouluun. Hän tutki kuinka tärkeinä vanhemmat pitivät kykyä, yrityksen määrää, tehtävien vaikeustasoa ja lapsen saamaa ohjausta selittämässä lasten onnistumista ja epäonnistumista koulussa. - Koulunsa aloittavien lasten vanhempia voisi neuvoa viestimään lapsilleen, että heillä on kykyjä onnistua haastavissakin koulutehtävissä. Tällainen viesti vaikuttaa positiivisesti lasten koulutaitojen kehitykseen ja minäkuvan muuttumiseen realistisemmaksi, Natale suosittaa.Onnistuminen kyvykkyyttä, epäonnistuminen yrityksen puutetta…

The disenchantment of professionals in a new, implemented model of primary health care in Spain: A structural equations model
1992
Abstract A new model of primary health care has been progressively implemented in Spain. Previous research (Peiro and Gonzalez-Roma 1991) suggested that the implementation of this new model has produced a kind of disenchantment—that is, an experience of negative surprise—among health care professionals involved. In the present paper, a structural equations model about the antecedents and consequences of the experience of surprise is tested in a sample of 432 health care professionals working in 44 Primary Health Care Teams (PHCT). The results obtained showed that the number of uncovered functions in the PHCTs, the discrepancy between actual and desired time allocation, and the assessment of…
