Una de las líneas críticas que ha calado con más fuerza en los estudios sobre Sor Juana Inés de la Cruz es la propuesta por Octavio Paz en su famoso libro Sor Juana Inés de la Cruz o las trampas de la Fe de 1982. En él, se plantea una lectura de la vida de esta monja a partir de una constante rebeldía frente a su entorno, básicamente, a causa de una condición que le habría de causar numerosos problemas siempre: su natural inclinación a los asuntos del conocimiento. Esta línea de lectura va a tener una influencia muy fuerte, sobre todo, en el estudio de sus últimos años, los cuales estuvieron marcados por la polémica en torno de la publicación de la Carta atenagórica sin su autorización en el mes de diciembre de 1690 por parte del obispo de Puebla, Manuel Fernández de Santa Cruz. En esa carta, de circulación privada en primera instancia, Juana Inés refutaba al teólogo portugués Antonio de Vieira por su Sermón del mandato. Tal publicación no consentida, además, fue acompañada por una carta en la que el propio Fernández de Santa Cruz, disfrazando su pluma como la monja Sor Filotea, responde a Sor Juana y le pide una dedicación más atenta a las letras sagradas. La respuesta a esta carta no se hizo esperar y, en marzo de 1691, saca a la luz Sor Juana la Respuesta a Sor Filotea de la Cruz en la cual establece una defensa del estudio de las mujeres y de su participación en la vida pública eclesiástica. / Tesis

Background: The traditional way of product promotion is no longer enough to attract the emerging consumer class; high-quality short video platforms have brought more business opportunities and dividends, providing a new channel for product marketing and promotion. The short video platform of TikTok has strong traffic attributes and intuitive product presentation, and many brands and merchants have shifted their product marketing and promotion positions here. However, brands and merchants lack a deep understanding of the internal mechanism of the influence of TikTok's short videos on the purchase intention of the consumer, cannot grasp the pain points of consumers' demand well, and lack attention to the online shopping experience of consumers. The existing researches mainly analyze the marketing strategies of short videos, and there are insufficient researches on consumers' purchase intention in the context of short videos on TikTok. Purpose: This thesis takes the consumer of TikTok short videos as the research object. Based on SOR theory, three main characteristics of TikTok short videos are selected as independent variables: entertainment, interactivity, and personalization. Meanwhile, social presence is introduced as the intermediary variable to explore the mechanism of influence of TikTok short videos' characteristics on consumers' purchase intention. Method: In this thesis, the questionnaire survey method was used to collect data, and 207 valid questionnaires were collected. Finally, SPSS26.0 statistical analysis software was used to process and analyze the data. Conclusion: The empirical results show that: (1) the entertainment, interactivity, and individuation of TikTok short videos have a positive impact on the purchase intention of the consumer; (2) TikTok short video entertainment, interactive, personalized positive impact on the consumer's sense of social presence; (3) Social presence plays a partial mediating role in the influence of entertainment, interactivity and personalization on purchase intention. According to the research conclusions, this thesis puts forward relevant suggestions for guiding enterprises to use short video platforms to carry out targeted and efficient precision marketing, stimulate the consumer's purchase intention, and maximize the use of short video as a differentiated marketing tool to cultivate their core competitiveness.

This M.A. thesis consists of a close-textual reading of Sor Juana Inés de la Cruz’s four sets of villancicos dedicated to the Assumption of the Virgin Mary (1676, 1679, 1685 and 1690), with a special focus on Sor Juana’s marianism and a contrast with Juan Correa’s painting, La Asunción de la Virgen (1689). This thesis will cover Sor Juana’s innovation in her representation of Mary as a model of femininity, Mary’s creative abilities, the crowning of Mary, Mary as a dwelling for God, Sor Juana’s feminization of the divine, Mary’s Assumption itself, masculine aspects and professions attributed to Mary, and Sor Juana’s identification with the Virgen.

Hierarchical Markovian Models (HMMs) are composed of multiple low level models (LLMs) and high level model (HLM) that defines the interaction among LLMs. The essence of the HMM approach is to model the system at hand in the form of interacting components so that its (larger) underlying continous-time Markov chain (CTMC) is not generated but implicitly represented as a sum of Kronecker products of (smaller) component matrices. The Kronecker structure of an HMM induces nested block partitionings in its underlying CTMC. These partitionings may be used in block versions of classical iterative methods based on splittings, such as block SOR (BSOR), to solve the underlying CTMC for its stationary vector. Therein the problem becomes that of solving multiple nonsingular linear systems whose coefficient matrices are the diagonal blocks of a particular partitioning. This paper shows that in each HLM state there may be diagonal blocks with identical off-diagonal parts and diagonals differing from each other by a multiple of the identity matrix. Such diagonal blocks are named candidate blocks. The paper explains how candidate blocks can be detected and how the can mutually benefit from a single real Schur factorization. It gives sufficient conditions for the existence of diagonal blocks with real eigenvalues and shows how these conditions can be checked using component matrices. It describes how the sparse real Schur factors of candidate blocks satisfying these conditions can be constructed from component matrices and their real Schur factors. It also demonstrates how fill in- of LU factorized (non-candidate) diagonal blocks can be reduced by using the column approximate minimum degree algorithm (COLAMD). Then it presents a three-level BSOR solver in which the diagonal blocks at the first level are solved using block Gauss-Seidel (BGS) at the second and the methods of real Schur and LU factorizations at the third level. Finally, on a set of numerical experiments it shows how these ideas can be used to reduce the storage required by the factors of the diagonal blocks at the third level and to improve the solution time compared to an all LU factorization implementation of the three-level BSOR solver.

Kronecker structured representations are used to cope with the state space explosion problem in Markovian modeling and analysis. Currently an open research problem is that of devising strong preconditioners to be used with projection methods for the computation of the stationary vector of Markov chains (MCs) underlying such representations. This paper proposes a block SOR (BSOR) preconditioner for hierarchical Markovian Models (HMMs) that are composed of multiple low level models and a high level model that defines the interaction among low level models. The Kronecker structure of an HMM yields nested block partitionings in its underlying continuous-time MC which may be used in the BSOR preconditioner. The computation of the BSOR preconditioned residual in each iteration of a preconditioned projection method becoms the problem of solving multiple nonsingular linear systems whose coefficient matrices are the diagonal blocks of the chosen partitioning. The proposed BSOR preconditioner solvers these systems using sparse LU or real Schur factors of diagonal blocks. The fill-in of sparse LU factorized diagonal blocks is reduced using the column approximate minimum degree algorithm (COLAMD). A set of numerical experiments are presented to show the merits of the proposed BSOR preconditioner.

For the containment, barriers or detours are usually made of synthetic materials such as polyurethane foam. In order to clear water away, techniques like in loco burning, biodegradant agents, dispersant agents and sorbent materials application are used. The most of the sorbent materials are also synthetic and they are used because it is easy to store them and their availability in market. This dissertation introduces the study of vegetable fibers of pineapple leaf fibers (Ananas comosus (L.) Merr.), cotton fibers (Gossypium herbaceum L.), kapok fibers (Ceiba pentandra (L.) Gaertn.), curau? fibers (Ananas erectifolius L.B. Sm.) and sisal fibers (Agave sisalana Perrine) related to their capacity of sorption of oil in case of accidental spill in the ocean.
