Darbam ir piecas nodaļas ar apakšnodaļām, ievads, secinājumi un pielikumi. Pirmajā nodaļā iepazīta Aspazijas personība un tās ietekme uz dzejnieces daiļradi, kā arī Aspazijas dzejas un drāmas specifika, uzsverot skolēniem noderīgo informāciju. Otrajā nodaļā ir apzināta teorētiskā literatūra par literatūru kā mācību priekšmetu un tā specifiku. Trešajā nodaļā ir aprakstīta skolotāja sagatavošanās darbam klasē, iekļaujot skolēnu vecumposma īpatnības, pētījumā iesaistīto skolēnu rakstu…
SARS-CoV-2 vaccine response and rate of breakthrough infection in patients with hematological disorders
2022
Abstract Background The clinical efficacy of SARS-CoV-2 vaccines according to antibody response in immunosuppressed patients such as hematological patients has not yet been established. Patients and methods A prospective multicenter registry-based cohort study conducted from December 2020 to December 2021 by the Spanish transplant and cell therapy group was used to analyze the relationship of antibody response at 3–6 weeks after full vaccination (2 doses) with breakthrough SARS-CoV-2 infection in 1394 patients with hematological disorders. Results At a median follow-up of 165 days after complete immunization, 37 out of 1394 (2.6%) developed breakthrough SARS-CoV-2 infection at median of 77 …
La sonrisa del éxito: figuraciones de una subjetividad exigida
2014
El presente artículo analiza cómo se afianza en la escena social la corporalidad del liderazgo. Para ello, aborda imágenes y narrativas que circulan en los entramados simbólicos de la cultura del bienestar, que también se denomina como cultura activa. El cuerpo del liderazgo se ofrece al público mediante estrategias positivas y negativas. Éstas, en la medida que encumbran el estilo de vida activo, demonizan aquellas prácticas que no responden a los valores sanitarios y productivos promulgados por el ethos empresarial emergente. Se concluye que la encarnación de una subjetividad emprendedora se impone paulatinamente como parámetro de integración de un individuo en los diagramas económicos y …
Public spending decisions and the role of municipalities in local development in Argentina: An approach from the municipal autonomy and social and po…
2018
El desarrollo endógeno es un tema prioritario en la agenda municipal, atento el rol de liderazgo que les compete a los gobiernos locales en este proceso. A raíz de distintos procesos de descentralización operados desde el nivel central de gobierno hacia los subnacionales, los municipios se han visto obligados a diseñar estrategias y políticas públicas conjuntas con los distintos actores locales, individuos, organizaciones, políticos y asociaciones de la sociedad civil en general, en la búsqueda de soluciones a las problemáticas que plantea la sociedad hoy. En este trabajo se intentará analizar cómo se inserta el gobierno local, en tanto articulador de los esfuerzos de la comunidad, dentro d…
De errores y erratas. Cómo corregir y normalizar un texto académico
2012
En el presente artículo, se intenta demostrar en primer lugar, a partir de ejemplos de una revista académica de lingüística, que errores y erratas tienen el mismo protagonismo en la corrección de textos académicos. Pero además, que los criterios y procedimientos de normalización – definida como el conjunto de decisiones y de procedimientos que tienden a unificar el estilo de un escrito en todos sus niveles– son fundamentales para que un conjunto de artículos científicos de autores varios o una serie de trabajos de un mismo autor, de distinto tema o etapas académicas, puedan llegar a convertirse en una publicación periódica o en un libro. In the present article, we first intend to demonstrat…
Diabetes and renin-angiotensin-aldosterone system: Implications for covid-19 patients with diabetes treatment management
2020
In the context of the COVID-19 continuous spreading, this paper focuses on the increased risk of diabetic patients regarding the metabolic control and the uncertainties related to SARS-CoV-2 infection. Chronic hyperglycaemia negatively affects the immune system, which triggers an increase of morbidity and mortality for viral infections. A key aspect of COVID-19 resides in the involvement of renin-angiotensin-aldosterone (RAAS) system that causes a cascade of reactions mediated by vasoactive peptides with implications in vasoconstriction, vascular permeability, oxidative stress remodelling and tissue injuries. Activation of RAAS at pulmonary level, is responsible for the local damage. Many q…
Volcanic structures investigation through SAR and seismic interferometric methods: The 2011-2013 Campi Flegrei unrest episode
2019
Observations from satellites provide high-resolution images of ground deformation allowing to infer deformation sources by developing advanced modeling of magma ascent and intrusion processes. Nevertheless, such models can be strongly biased without a precise model of the internal structure of the volcano. In this study, we jointly exploited two interferometric techniques to interpret the 2011–2013 unrest at Campi Flegrei caldera (CFc). The first is the Interferometric Synthetic Aperture Radar (InSAR) technique, which provides highly-resolved spatial and temporal images of ground deformation. The second is the Ambient Noise Tomography (ANT), which images subsurface structures, providing the…

Diving below the spin-down limit: Constraints on gravitational waves from the energetic young pulsar PSR J0537-6910
2021
We present a search for continuous gravitational-wave signals from the young, energetic X-ray pulsar PSR J0537-6910 using data from the second and third observing runs of LIGO and Virgo. The search is enabled by a contemporaneous timing ephemeris obtained using NICER data. The NICER ephemeris has also been extended through 2020 October and includes three new glitches. PSR J0537-6910 has the largest spin-down luminosity of any pulsar and is highly active with regards to glitches. Analyses of its long-term and inter-glitch braking indices provided intriguing evidence that its spin-down energy budget may include gravitational-wave emission from a time-varying mass quadrupole moment. Its 62 Hz …
Subarcsecond Location of IGR J17480-2446 with Rossi XTE
2012
On 2010 October 13, the X-ray astronomical satellite Rossi XTE, during the observation of the newly discovered accretion powered X-ray pulsar IGR J17480--2446, detected a lunar occultation of the source. From knowledge of lunar topography and Earth, Moon, and spacecraft ephemeris at the epoch of the event, we determined the source position with an accuracy of 40 mas (1{\sigma} c.l.), which is interesting, given the very poor imaging capabilities of RXTE (\sim 1\circ). For the first time, using a non-imaging X-ray observatory, the position of an X-ray source with a subarcsecond accuracy is derived, demonstrating the neat capabilities of a technique that can be fruitfully applied to current a…
