Uwarunkowania parentyfikacji doświadczanej w dzieciństwie i okresie dorastania z perspektywy młodych dorosłych
2017
Parentification has also been known and studied as role reversal in family. Despite the fact that this concept entered scientific literature in the 1970’s, it has not received adequate attention and its causes and mechanisms have not been fully established. In Poland, parentification has been on the margins of psychological research and its prevalence, causes, and effects are unknown. Consequently, there is lack of practical guidelines for practitioners working with families in which role reversal might have taken place. The goal of this study is to gain insight into the prevalence, conditions, and types of parentification retrospectively reported by young adults reflecting on their family …
Moros y cristianos. De la batalla festiva a la discursiva
2008
Hace poco más de un año se acordaba en España admitir a trámite en el Congreso de los Diputados la proposición no de ley del Grupo Parlamentario Popular relativa a la proclamación de las "fiestas de moros y cristianos" como obras maestras del patrimonio oral e inmaterial de la humanidad. La solicitud se contextualiza en la democratización y universalización que el patrimonio ha experimentado y se explica por la vertiente cada vez más mercantilista de los procesos de patrimonialización. En el caso que nos ocupa la presentación estuvo envuelta en una interesante discusión política sobre la "tradición", la "libertad" y la "amenaza". Este artículo analiza la polémica sobre estas fiestas y su pr…
Walsh function analysis of 2-D generalized continuous systems
1990
The importance of the generalized or singular 2D continuous systems are demonstrated by showing their use in the solution of partial differential equations in two variables. A technique is presented for solving these systems in terms of Walsh functions. The method replaces the solution of a two-variable partial differential equation with the solution of a linear algebraic generalized 2D Sylvester equation. An efficient technique for the recursive solution of the latter equation is offered. All the results apply also in the usual Roesser 2D state-space case. >
Preparing students to participate to the didactic activities of university teacher
2016
«Student Voice» è un movimento pedagogico nato negli anni Novanta nei Paesi di lingua inglese (Stati Uniti, Canada, Inghilterra e Australia): esso sostiene la partecipazione attiva e responsabile degli studenti che frequentano la scuola e l’università nella didattica dei docenti, nella ricerca universitaria e nelle politiche educative e culturali che li riguardano. Nella ricerca sperimentale qui presentata, si è voluta prestare attenzione alla partecipazione degli studenti universitari (n. 33) alle attività didattiche di un docente di pedagogia sperimentale. Si è scelto di adottare due metodi d’intervento: la scrittura espressiva, come metodo di analisi del futuro prefigurato nelle aspettat…
Search for diphoton events with large missing transverse energy in 7 TeV proton-proton collisions with the ATLAS detector.
2011
A search for diphoton events with large missing transverse energy is presented. The data were collected with the ATLAS detector in proton-proton collisions at √s=7 TeV at the CERN Large Hadron Collider and correspond to an integrated luminosity of 3.1 pb−1. No excess of such events is observed above the standard model background prediction. In the context of a specific model with one universal extra dimension with compactification radius R and gravity-induced decays, values of 1/R<729 GeV are excluded at 95% C. L., providing the most sensitive limit on this model to date.
Observation of Time-Reversal Violation in the B0 Meson System
2012
Although CP violation in the B meson system has been well established by the B factories, there has been no direct observation of time reversal violation. The decays of entangled neutral B mesons into definite flavor states ($B^0$ or $\bar{B}^0$), and $J/\psi K_S^0$ or $c\bar{c} K_S^0$ final states (referred to as $B_+$ or $B_-$), allow comparisons between the probabilities of four pairs of T-conjugated transitions, for example, $\bar{B}^0 \rightarrow B_-$ and $B_- \rightarrow \bar{B}^0$, as a function of the time difference between the two B decays. Using 468 million $B\bar{B}$ pairs produced in $\Upsilon(4S)$ decays collected by the BABAR detector at SLAC, we measure T-violating parameter…
Measurements of the tau polarisation in Z0 decays
1995
A sample of Z0→τ+τ- events observed in the DELPHI detector at LEP in 1991 and 1992 is analysed to measure the τ polarisation in the exclusive decay channels {Mathematical expression}, {Mathematical expression}, πν, ρν and a1ν. The τ polarisation is also measured with an inclusive hadronic analysis which benefits from a higher efficiency and a better systematic precision than the use of the exclusive decay modes. The results have been combined with those published on the 1990 data. A measurement of the τ polarisation as a function of production angle yields the values for the mean τ polarisation 〈P〉τ=-0.148±0.022 and for the Z0 polarisation PZ=-0.136±0.027. These results are used to determin…
Hadronic τ Decays as New Physics Probes in the LHC Era
2019
We analyze the sensitivity of hadronic tau decays to non-standard interactions within the model-independent framework of the Standard Model Effective Field Theory (SMEFT). Both exclusive and inclusive decays are studied, using the latest lattice data and QCD dispersion relations. We show that there are enough theoretically clean channels to disentangle all the effective couplings contributing to these decays, with the $\tau \to \pi\pi\nu_\tau$ channel representing an unexpected powerful New Physics probe. We find that the ratios of non-standard couplings to the Fermi constant are bound at the sub-percent level. These bounds are complementary to the ones from electroweak precision observable…
Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector
2012
A search for diphoton events with large missing transverse momentum has been performed using proton–proton collision data at √s = 7 TeV recorded with the ATLAS detector, corresponding to an integrated luminosity of 4.8 fb[superscript −1]. No excess of events was observed above the Standard Model prediction and model-dependent 95% confidence level exclusion limits are set. In the context of a generalised model of gauge-mediated supersymmetry breaking with a bino-like lightest neutralino of mass above 50 GeV, gluinos (squarks) below 1.07 TeV (0.87 TeV) are excluded, while a breaking scale Λ below 196 TeV is excluded for a minimal model of gauge-mediated supersymmetry breaking. For a specific …
Modelling the spatial and temporal constrains of the GABAergic influence on neuronal excitability
2021
GABA (γ-amino butyric acid) is an inhibitory neurotransmitter in the adult brain that can mediate depolarizing responses during development or after neuropathological insults. Under which conditions GABAergic membrane depolarizations are sufficient to impose excitatory effects is hard to predict, as shunting inhibition and GABAergic effects on spatiotemporal filtering of excitatory inputs must be considered. To evaluate at which reversal potential a net excitatory effect was imposed by GABA (EGABAThr), we performed a detailed in-silico study using simple neuronal topologies and distinct spatiotemporal relations between GABAergic and glutamatergic inputs. These simulations revealed for GABAe…
