Evolució de la sintaxi dels contextos de polaritat negativa en castellà i català
2007
In this paper we would like to compare the evolution of the syntax of polar contexts in Catalan and Spanish. By doing so, it would be possible to explain the greater syntactic disponibility of Catalan quantifiers and the important constraints for the same class of words in Spanish. After presenting in the first section the main theoretical questions about polarity in natural languages, we will describe in the second section the syntax of corresponding contexts in Middle Ages for both languages. Then, in the third section we will attend to the evolution towards current situation in order to understand the nature of modern differences between Catalan and Spanish on this area of their syntax.
Os pupi sicilianos: memória, tradição e inovação de um patrimônio artístico e cultural
2018
L’opra dei pupi è il teatro tradizionale delle marionette in Sicilia. Per la sua importanza è specificità è stato riconosciuto dall’UNESCO quale “capolavoro del patrimonio orale e immateriale dell’umanità”. La sua forma tipica, caratterizzata da temi narrativi cavallereschi e da pupi armati, ha avuto origine nella prima metà dell’Ottocento differenziandosi in due distinte tradizioni: quella palermitana e quella catanese. Teatro tipicamente popolare dalle evidenti caratteristiche rituali, l’opra entra in crisi a metà del Novecento a causa delle trasformazioni socio-economiche e dell’affermarsi di nuove forme di intrattenimento (cinema, televisione). Conosce però una rifioritura, mostrando la…
Borderline Personality in Patients with Poly-Diagnoses Treated for a Bipolar Disorder
2019
Some patients with dysphoria, explosive behaviour, or suicidal ideation, may receive a diagnosis of, and treatment for Bipolar Disorder (BD) and, not infrequently. The coexistence of these two diagnoses has been explained in different ways. Some authors include the BPD in the bipolar spectrum; others are sceptical about the existence of real comorbidity, suggesting a misdiagnosis. This study aimed to assess the personality of this group of poly-diagnosed patients (PolyD) and hypothesised they had a pathological borderline organisation. Via the administration of the Schedler Westen Assessment Procedure (SWAP-200), we compared PolyD patients with those suffering from BPD or BD only. We perfor…
Atención y procesamiento emocional en personas con trastorno bipolar
2014
Las personas con trastorno bipolar se caracterizan por una desregulación emocional que afecta a cómo atienden a la información que les rodea. Investigaciones recientes han encontrado sesgos atencionales en las personas con trastorno bipolar, tanto cuando su estado de ánimo es bajo (mayor atención a palabras negativas y rostros tristes) como cuando su estado de ánimo es elevado (mayor atención a palabras positivas y caras alegres). Es importante destacar que, en personas con depresión, estos sesgos pueden entrenarse de manera que disminuye la sintomatología afectiva. Esta opción podría contemplarse como una nueva alternativa de intervención en el trastorno bipolar.
Pole-to-Pole Connections: Similarities between Arctic and Antarctic Microbiomes and Their Vulnerability to Environmental Change
2017
The global biogeography of microorganisms remains poorly resolved, which limits the current understanding of microbial resilience toward environmental changes. Using high-throughput 16S rRNA gene amplicon sequencing, we characterized the microbial diversity of terrestrial and lacustrine biofilms from the Arctic, Antarctic and temperate regions. Our analyses suggest that bacterial community compositions at the poles are more similar to each other than they are to geographically closer temperate habitats, with 32% of all operational taxonomic units (OTUs) co-occurring in both polar regions. While specific microbial taxa were confined to distinct regions, representing potentially endemic popul…
Staging, neurocognition and social functioning in bipolar disorder.
2018
Introduction: Bipolar disorder (BD) is associated with significant neurocognitive and functional impairment, which may progress across stages. The ‘latent stage' of BD remains understudied. This cross-sectional study assessed staging, neurocognition and social functioning among BD patients and their healthy siblings.Methods: Four groups were included: euthymic type I BD patients in the early (n = 25) and late (n = 23) stages, their healthy siblings (latent stage; n = 23) and healthy controls (n = 21). All 92 subjects underwent a comprehensive neuropsychological battery of processing speed, verbal learning/memory, visual memory, working memory, verbal fluency, executive cognition, and motor …
Resonance in Interacting Induced-Dipole Polarizing Force Fields: Application to Force-Field Derivatives
2009
The Silberstein model of the molecular polarizability of diatomic molecules, generalized by Applequist et al. for polyatomic molecules, is analyzed. The atoms are regarded as isotropically polarizable points located at their nuclei, interacting via the fields of their induced dipoles. The use of additive values for atom polarizabilities gives poor results, in some cases leading to artificial predictions of absorption bands. The molecular polarizability of methane and its derivative are computed. The agreement with experimental mean molecular polarizabilities is within 1–5%. A hypothesis is indispensable for a suitable representation of polarizability derivative.
Spectroscopic and Structural Investigation of the Confinement of D and L Dimethyl Tartrate in Lecithin Reverse Micelles
2009
The confinement of D and L dimethyl tartrate in lecithin reverse micelles dispersed in cyclohexane has been investigated by FT-IR, polarimetry, electronic and vibrational circular dichroism (ECD and VCD), 1H NMR, and small-angle X-ray scattering (SAXS). Measurements have been performed at room temperature as a function of the solubilizate-to-surfactant molar ratio (R) at fixed lecithin concentration. The analysis of experimental data indicates that the dimethyl tartrate molecules are solubilized within reverse micelles in proximity to the surfactant head groups in the same way for the D and L forms. The encapsulation of dimethyl tatrate within lecithin reverse micelles involves changes in i…
