Spanish Adaptation of the Left-Wing Authoritarianism Index

2021

Notwithstanding long-simmering controversies around the construct, several studies have gathered consistent evidence of authoritarian attitudes among left-wing voters and activists. Recently, Costello et al. (Clarifying the structure and nature of left-wing authoritarianism. Journal of Personality and Social Psychology, 2021) validated, in the English-speaking context, a three-factor scale to measure left-wing authoritarianism, as well as two shortened versions of the same scale (Costello & Patrick, Development and initial validation of two brief measures of left-wing authoritarianism: A machine learning approach, 2021; composed of 39, 25 and 13 items, respectively). In this article, we use…

From fringe to fringe: the shift from the clericalist League of Polish Families to the anticlericalist Palikot Movement 2001–2015

2017

The period between 2001 and 2015 brought two events in Poland that deserve to be called phenomena. In 2001 the rightist, clericalist League of Polish Families entered the Sejm. Ten years later, the leftist, anticlericalist Palikot Movement achieved spectacular success in the 2011 elections. These events give a picture of a radical shift in the Polish political scene: a rightist clericalist party disappeared from the right flank of the political scene, while a new, leftist-anticlericalist formation appeared. The article makes reference to a set of five explanations on both the causes and consequences (and permanence) of the observed changes. I argue that only a concurrence of a number of com…

Speckle tracking analysis: a new tool for left atrial function analysis in systemic hypertension: an overview

2014

Speckle tracking echocardiography (STE) is an imaging technique applied to the analysis of left atrial function. STE provides a non-Doppler, angle-independent and objective quantification of left atrial myocardial deformation. Data regarding feasibility, accuracy and clinical applications of left atrial strain are rapidly gathering. This review describes the fundamental concepts of left atrial STE, illustrates its pathophysiological background and discusses its emerging role in systemic arterial hypertension.

Bayesian joint ordinal and survival modeling for breast cancer risk assessment

2016

We propose a joint model to analyze the structure and intensity of the association between longitudinal measurements of an ordinal marker and time to a relevant event. The longitudinal process is defined in terms of a proportional-odds cumulative logit model. Time-to-event is modeled through a left-truncated proportionalhazards model, which incorporates information of the longitudinal marker as well as baseline covariates. Both longitudinal and survival processes are connected by means of a common vector of random effects. General inferences are discussed under the Bayesian approach and include the posterior distribution of the probabilities associated to each longitudinal category and the …

Triply Factorised Groups and the Structure of Skew Left Braces

2021

The algebraic structure of skew left brace has proved to be useful as a source of set-theoretic solutions of the Yang–Baxter equation. We study in this paper the connections between left and right $$\pi $$ -nilpotency and the structure of finite skew left braces. We also study factorisations of skew left braces and their impact on the skew left brace structure. As a consequence of our study, we define a Fitting-like ideal of a left brace. Our approach depends strongly on a description of a skew left brace in terms of a triply factorised group obtained from the action of the multiplicative group of the skew left brace on its additive group.

Registration and fusion of segmented left atrium CT images with CARTO electrical maps for the ablative treatment of atrial fibrillation

2005

This study aims to extract the interior surface of the left atrium (LA) and pulmonary veins (PVs) from threedimensional tomographic data and to integrate it with LA CARTO electrical maps. The separation of LA and PVs from other overlapping structures of the heart was performed processing 3D CT data by marker-controlled watershed segmentation and surface extraction. CARTO maps were then registered on the L A internal surface by a stochastic optimization algorithm based on simulated annealing. The residual registration error resulted inferior to 3 mm. The integration between electrophysiological and high resolved anatomic information of LA results feasible and may constitute a significant sup…

Easy removal of a large mucus plug with a flexible paediatric bronchoscope after administration of rhDNase (Pulmozyme).

2006

Mucoid impaction and plastic bronchitis are relatively rare disorders affecting patients of any age. Here we report the case of mucoid impaction developing in a four-year-old child as a complication of pneumonic infection treated four weeks prior. p.a. chest X-ray and fiberoptic bronchoscopy showed atelectasis and the location of a mucus cast in the left upper lobe. After extraction of the cast via the suction channel of the bronchoscope had failed, we administered 2.5 mg of undiluted recombinant human deoxyribonuclease (rhDNase) instilled directly over the affected area of occlusion for 15 minutes. This mucolytic agent mobilized the cast by reducing viscoelasticity and adherence of mucus. …

Echocardiographic Assessment of Ventricular Septal Rupture and Left Ventricular Aneurysm after Inferior and Posterior Myocardial Infarction

2018

We present a case of posterior ventricular septal rupture associated to left ventricular aneurysm manged, during peri-operative period, by transthoracic and transesophageal echocardiography. Three-dimensional transesophageal echocardiography findings add adjunctive and more accurate information regarding morphological details of the ventricular septal rupture rather than two-dimensional echocardiography, allowing, meanwhile, the detection of the outcome of the surgical repair.

A Few Remarks on the Left Periphery in Indo-European

2011

The paper is organized as follows: the first section describes the different perspectives which separate generative historical linguistics and conventional comparative philology; since a generative approach to Indo-European linguistics does not appear more hypothetical than the way of dealing with de syntax of the ancestor language adopted by conventional comparative philology, in the second section an attempt is made to apply the formal apparatus of generative grammar to Indo-European syntax by making some brief remarks about the so-called left periphery of the sentence of the proto-language.
