Solving Non-linear Rational Expectations Models By Eigenvalue-Eigenvector Decompositions
No full textThis code supports the text in Alfonso Novales, Emilio Dominguez, Javier J. Perez and Jesus Ruiz, Solving Non-linear Rational Expectations Models By Eigenvalue-Eigenvector Decompositions, in Ramon Marimon and Andrew Scott (eds), Computational Methods for the Study of Dynamic Economies, Chapter 4, Oxford University Press. This chapter deals with a solution to rational expectations models, which is based on eigenvalue/eigenvector decompositions. The methods gives an exact solution in th case of linear expectations and an approximate solution in the case of nonlinear models. The programs execute the calculations of sections 4 and 6 of the chapter.
The problem of the author in a short story by Reinaldo Arenas
Get PDFEn el relato Final de un cuento del escritor cubano Reinaldo Arenas, las semejanzas del yo enunciativo con la biografía de Arenas son evidentes, si bien en ningún momento el yo enunciativo lleva el nombre del autor empírico. Propongo entonces una lectura autoficcional que permita dar cuenta no sólo de la peculiar simbiosis que facticidad y ficcionalidad crean en el relato, sino también del estatuto ontológico de la voz enunciativa.The similarities between the narrator and the biography of the empirical author in the short story “Final de un cuento” by the Cuban writer Reinaldo Arenas are evident. Nevertheless that narrator is never named “Reinaldo Arenas” in the story. I therefore propose an autofictional reading which explains the peculiar symbiosis between factuality and fictionallity, as well as the ontological status of the narrator
Analysis of irradiated Argentinean fetal bovine serum for adventitious agents
Get PDFFetal bovine serum (FBS) used in cell culture may be contaminated with adventitious agents, which can affect the production of biologicals and the results of clinical laboratory tests. We carried out a retrospective study to determine the incidence of adventitious agent contamination of Argentinean irradiated FBS dating from 2015 to 2019. We analyzed FBS batches for mycoplasma and adventitious viruses (bovine pestiviruses, bovine adenovirus, bluetongue virus, bovine parainfluenza virus 3, rabies virus, bovine parvovirus, bovine herpesvirus 1, bovine respiratory syncytial virus, and reovirus). Cell passages followed by direct immunofluorescence were carried out to check viability of the mentioned adventitious agents. Also, molecular detection of mycoplasma and pestiviruses was performed on the FBS samples. The presence of neutralizing antibodies against pestiviruses was determined. Molecular analyses indicated that frequencies of mycoplasma and pestiviruses in FBS were 14% and 84%, respectively. All of the batches were seronegative for pestiviral antibodies. After cell passages, all FBS samples were negative for hemadsorbent agents and by immunofluorescence for all of the viral species analyzed; PCR assays were negative for mycoplasma and pestiviruses. Our results demonstrate that, of all adventitious agents tested, local FBS batches only had traces of mycoplasma and pestiviruses; gamma irradiation was effective in inactivating them.Instituto de VirologíaFil: Pecora, Andrea.

La mentira como componente identitario en La verdad sospechosa de Juan Ruiz de Alarcón /
No full textThis work focuses on the topic of identity and, particularly, on the study of lies as a component of identity through the analysis of the main character in the comedy La verdad sospechosa , and the Court represented in the play. The text has been divided into two sections: the text's reality and the stories invented by the main character. This distinction serves to establish the relation between the elements of both parts, as well as their consequent influence in the construction of the character's identity. Conditions such as space, time and, particularly, social surrounding are taken into account in the fabrication of lies. The work shows how lying serves as a tool to create, sometimes fictitious but nevertheless useful, routes that help achieve an immersion in the society, even if it seems to go completely against the social values that, on the other hand, helps attain. Through the deconstruction of the character's lies, this work shows how, gradually, the made-up stories assimilate with the reality of the text until they become one with it. This gradual assimilation goes hand in hand with the character's immersion into the community, which includes the learning of social values and the fulfillment of the community's expectations
Analysis of the dance guard in bucaramanga: a cultural economy approach
No full textCuantificar los fenómenos culturales a través de las herramientas brindadas por la economía, ha sido uno de los grandes retos por los que las regiones en el mundo se encuentran afrontando. El sector cultural se divide en 7 subsectores, según el Ministerio de Cultura, dentro de los cuales el sector de las artes escénicas, particularmente el sector de la danza, será el estudiado en el presente trabajo. Por medio de la realización de encuestas, entrevistas semiestructuradas y un análisis descriptivo del sector, se puede describir que en la ciudad de Bucaramanga se cuenta actualmente con alrededor de 39 agrupaciones activas en producción de espectáculos en vivo y en formación danzaría, dentro de los cuales 203 personas reciben remuneración directa o indirecta del sector, enfrentándose a situaciones no favorables en relación con la calidad de vida. Para lograr un mejoramiento es necesario formalizar la educación en danza en la región, velar por las garantías de calidad de vida de los artistas y así mismo fortalecer los canales de divulgación del sector, de manera que la oferta en danza pueda crear su propio público demandante y así mismo poder hacer del gremio dancístico un gremio cambiante e incidente en la ciudad.PregradoEconomistaQuantifying cultural phenomena through the tools provided by the economy has been one of the major challenges facing regions in the world.

To achieve an improvement, it is necessary to formalize dance education in the region, to ensure the quality of life guarantees of the artists and also to strengthen the channels of dissemination of the sector, so that the dance offer can create its own demanding public and also be able to make the dance guild a changing and incident guild in the city
International Prevalence of Technology-Facilitated Sexual Violence Against Women: A Systematic Review and Meta-Analysis of Observational Studies.
No full textThe aim of the present review was to systematically identify and examine current knowledge regarding the frequency of any form of technology-facilitated sexual violence (TFSV) perpetrated against women aged 16 years and older. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was applied when performing the present review. Observational studies reporting prevalence data for any form of TFSV against women aged 16 years and above were considered for inclusion. Four meta-analyses were conducted. One examined data pertaining to overall TFSV, while the other three each addressed a key dimension based on the type of victimization under study. Random-effects models were used to compute pooled estimate prevalences (95% CI). Included studies reported prevalence in 32 different countries at different time points, with 28,220 women being interviewed (16-97 years). A total of 1,437 potential articles were gathered from 8 databases and 17 studies were selected for analysis. Included studies exhibited a low risk of bias (12 strong methodological quality-5 medium). Rates of TFSV ranged from 2.2% to 84%. Global estimated prevalence was 30.60% (95% CI [24.08, 37.12]). The most frequently reported behaviors pertained to "digital sexual harassment" (28.54%) followed by "technology-facilitated aggression and coercion" (16.93%) and "image-based sexual abuse" (6.48%). Present findings shed light on a significant gap in understanding the experiences of adult women. The wide range of reported frequencies underscores the importance of unifying terms and standardizing measurement instruments, emphasizing the need for a cohesive approach to better comprehend and address the multifaceted nature of TFSV.Ye
