Factores determinantes internos y externos del sector turístico en Cuba: un análisis causal basado en mapas causales
Get PDFTrabajo de Máster Universitario en Economía, Finanzas y Computación (2023-24). Tutor: Dr. Antonio Jesús Sánchez Fuentes. El presente trabajo se enfoca en analizar las interacciones entre el turismo y la economía cubana,
utilizando una metodología integral con un enfoque conservador, que incluye el análisis de las
relaciones de causalidad de Granger entre los ingresos turísticos y diversas variables económicas
tanto internas como externas. Para realizar este estudio, se ha contemplado el período
comprendido entre los años 1980 a 2019, excluyendo el período de la COVID-19, para garantizar
la validez y la fiabilidad de los resultados, eliminando las distorsiones temporales generadas por
la pandemia. Durante este análisis se han considerado variables internas como los ingresos
turísticos (IT), el producto interno bruto (PIB), la inversión en infraestructura turística (INVIT) y
la generación de empleo (EST), así como su interrelación con variables externas como el PIB
global de los principales emisores de turistas a Cuba (EXT), los precios del petróleo (PET) y el
Índice de Precios al Consumidor a nivel global (Infl). De esta manera, se ha desarrollado un
modelo general que balancee sus efectos específicos de manera simultánea. Los resultados
obtenidos evidencian que más allá de la inversión en infraestructura turística, los ingresos
turísticos de Cuba se ven notablemente influenciados por el ciclo económico de los principales
países emisores, subrayando la importancia de una gestión económica adaptativa y estratégica
que permita anticipar y adaptarse a los cambios del ciclo económico de estos países. Se utilizó el
método de vectores autorregresivos (VAR) y causalidad de Granger, lo cual nos proporcionó una
estructura dinámica para comprender estas complejas relaciones. Dicho estudio pone de
manifiesto la necesidad de un análisis exhaustivo que tome en consideración tanto factores
internos como externos a la hora de realizar formulaciones de políticas y estrategias turísticas en
la isla, ofreciendo una perspectiva integral para la toma de decisiones futuras.This work focuses on analyzing the interactions between tourism and the Cuban economy, using
a comprehensive methodology with a conservative approach that includes the analysis of
Granger causality relationships between tourist income and various economic variables, both
internal and external. To carry out this study, the period from 1980 to 2019 has been considered,
excluding the COVID-19 period, to guarantee the validity and reliability of the results by
eliminating temporal distortions generated by the pandemic. During this analysis, internal
variables such as tourism income (TI), gross domestic product (GDP), investment in tourism
infrastructure (INVIT) and employment generation (EST) have been considered, as well as their
interrelationship with external variables such as Global GDP of the main issuers of tourists to
Cuba (EXT), oil prices (PET) and the global Consumer Price Index (Infl). In this way, a general
model has been developed that balances its specific effects simultaneously. The results obtained
show that beyond investment in tourism infrastructure, Cuba's tourism income is notably
influenced by the economic cycle of the main emitting countries, underlining the importance of
adaptive and strategic economic management that allows anticipating and adapting to the
changes in the economic cycle of these countries. The vector autoregressive (VAR) method and
Granger causality were used, which provided us with a dynamic structure to understand these
complex relationships. This study highlights the need for an exhaustive analysis that takes into
consideration both internal and external factors when formulating tourism policies and strategies
on the island, offering a comprehensive perspective for future decision-making
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
