Sociabilitat i projecció poètica : veus de dones en els certàmens literaris barrocs
2018
L’objectiu d’aquest treball és mostrar una tradició poètica femenina de certamen que ha perviscut al llarg dels segles, tot centrant-nos en el moment de màxim esplendor, el Barroc. La nostra intenció és visibilitzar aquest focus de difusió des de la perspectiva de la creació i la circulació d’alguns dels primers textos impresos atribuïts a les dones en la història de les nostres lletres, amb poesia tant en llengua catalana i castellana com —molt escassament— llatina. Per fer-ho, després d’haver dut a terme una recerca exhaustiva sobre l’univers dels certàmens dels segles XVI-XVII, i de sistematitzar-ne la producció, oferim algunes observacions de caire sociològic i literari relacionades amb…
An approach towards the visual culture of the Barroque festival : portraits of visual presences
2014
ABSTRACT: In this study I deal briefly with some issues related to the visual culture of the Baroque festival; and more specifically, with those related to the royal portraits that were on display during the festive activities. To this end I place special emphasis on developing the concepts of presence, body and virtuality –as applied to those works or visual objects– from an approach that offers a new theoretical framework, namely, that which involves «image studies» or «visual culture studies» (Bildwissenschaft, Bildanthropologie y visual studies). KEYWORDS: Baroque Festival, Royal Portraits, Presence, Body, Virtuality, Image Studies. RESUMEN: En el presente estudio abordaremos brevemente…
Optimal reciprocals in German Sign Language
2003
Unlike most spoken languages, German Sign Language (DGS) does not have a single means of reciprocal marking. Rather, different strategies are used, which crucially depend on phonological (one-handed sign vs. two-handed sign) and morphosyntactic (plain verb vs. agreement verb) properties of the underlying verb. Moreover, with plain verbs DGS shows dialectal variation. Altogether there are four different ways of realizing reciprocal marking in DGS. In this paper, we compare a rule-based analysis for the reciprocal data (based on Brentari’s 1998 feature hierarchy) to an optimality-theoretic analysis. We argue that an OT-account allows for a more straightforward explanation of the facts. In par…
Conducting a task while reconstructing its meaning
2022
This article investigates the way an institutional task of a meeting is oriented to by different meeting participants and developed in and through local interaction. Our data come from a city organization, where a large organizational change is planned and prepared through a series of face-to-face encounters and accompanying written texts. Using the notion of recontextualization and by connecting it to the conversation analytical method and to the notion of intersubjectivity, the study examines how the institutional task that is verbalized in written form prior to the meeting is conceptualized by meeting participants in their turns of talk. By doing so, the study will particularly shed ligh…
Sobre la particular devoció d’una ploma «desalinyada» per un «singular ingeni»: una lectura del «Cicle dels rams» de Francesc Fontanella
2020
El present treball representa la primera aproximació crítica monogràfica al Cicle dels rams, un conjunt de 29 cartes poètiques que Francesc Fontanella va escriure al Rosselló durant la seva etapa de maduresa. L'estudi es divideix en sis parts. La primera és dedicada a identificar i delimitar el cicle. La segona és una descripció sumària dels textos que explica tant els seus aspectes formals com el seu contingut, i assenyala els elements que confereixen sentit unitari al cicle. A la tercera part s'analitza el discurs amorós de les composicions, fent especial èmfasi en la seva singularitat dins la lírica amorosa fontanellana. La quarta part argumenta que els textos, partint d’una circumstànci…
The synthesis and effect of fluorinated chalcone derivatives on nitric oxide production
2002
Abstract Dimethoxy- and trimethoxychalcone derivatives, with various patterns of fluorination, were synthesized and evaluated for their influence on nitric oxide production. Some of them, chalcones 1 , 5 , 7 , 10 , 11 and 17 , inhibited NO production with an IC 50 in the submicromolar range; 17 is especially noteworthy because of its potency (IC 50 30 nM). These effects were not the consequence of a direct inhibitory action on enzyme activity but the inhibition of enzyme expression.
Chitosomes loaded with cranberry proanthocyanidins attenuate the bacterial lipopolysaccharide-induced expression of iNOS and COX-2 in raw 264.7 macro…
2009
Chitosan binds to negatively charged soy lecithin liposomes by an electrostatic interaction driven by its positively charged amino group. This interaction allows stable covered vesicles (chitosomes) to be developed as a suitable targeted carrier and controlled release system. This study investigated the effect of chitosomes on the activation of cranberry proanthocyanidins (PAC) in Raw 264.7 macrophages. Chitosomes were characterized according to size, zeta potential, PAC-loading, and release properties. Results showed an increase in the net positive charge and size of the liposomes as the concentration of chitosan was increased, suggesting an effective covering of the vesicles by means of e…
QT Indexes in Cirrhotic Patients: Relationship with Clinical Variables and Potential Diagnostic Predictive Value.
2015
Background and Aims A wide spectrum of cardiovascular changes characterizes cirrhosis, ranging from subclinical alterations to hyperkinetic syndrome. We looked for ECG markers of ventricular repolarization in a population of patients with cirrhosis in comparison to patients without cirrhosis and we investigated the relationship between these and other clinical and laboratory variables. Methods In 149 patients with cirrhosis and 152 controls, we measured QT maximum interval (QTmax), QT corrected interval (QTc), QT minimum interval (QTmin), QT dispersion (QTdisp), QT peak and T peak-to-end (TpTe). Results In subjects with cirrhosis, in comparison with controls, we observed a higher mean QTmax…
Cardiac involvement in patients with cirrhosis: a focus on clinical features and diagnosis
2016
Cirrhotic heart has been traditionally considered protected from cardiovascular disease, even if a large amount of literature has recently shown that patients affected by chronic liver disease are exposed to cardiovascular events, as well. Since the first recognition of cardiac involvement in cirrhosis, all published studies explain that decompensated cirrhotic patients suffer from haemodynamic changes, currently known as hyperdynamic syndrome, which finally lead to cirrhotic cardiomyopathy. This is defined by the presence of a subclinical systolic dysfunction unmasked under stress conditions, impaired diastolic function and electrophysiological abnormalities, in the absence of any known ca…
Rumination for innovation? : analyzing the longitudinal effects of work-related rumination on creativity at work and off-job recovery
2017
ABSTRACTWork-related rumination is not a single construct, but consists of a dimension associated with negative emotions or affect (affective rumination), and a dimension associated with reflective thinking and applying strategies to solve problems (problem-solving pondering). In this three-wave longitudinal study across two years (N = 630) we investigated whether the relationships between work-related rumination, off-job recovery, and creativity at work varied along the two dimensions of work-related rumination. In addition, we tested whether the relationships followed normal, reversed, or reciprocal causation. The results showed, first, that in a one-year perspective affective rumination,…
