Urban utopias in Havana's representations. An interdisciplinary analysis
This investigation consists of an interdisciplinary analysis of photographic, cinematographic, architectural and literary documents representing the city of Havana in Cuba during different periods of the twentieth century. These periods are: the decade of the Great Depression; the 1950s during the rapid growth of the tourist industry in the island; the first fifteen years following the 1959 Cuban Revolution; and the so-called 'Special Period' during the 1990s, following the collapse of the Soviet Union. It was during these periods that the city went
through very important transformations due to historical and cultural contingencies. These contingencies refer to the beginnings of the development of the city as a tourist centre, the first debates and cultural manifestations related to the Afro-Cuban traditions in the island, the post - 1959 evolutionary processes and the effects of the end of the Cold War on the city. The documents analysed have been drawn firstly from cultural productions made by Cubans: Cuban filmography and photography pre- and post-1959. Secondly, there are also those documents produced by non-Cubans, mainly Hollywood productions and other types of representation, which have also contributed greatly to create a particular image of Havana. An important part of this analysis also includes the architectural particularities of the city, with an emphasis on the symbology of some of its main buildings, such as the Capitolio and the National Hotel.
This analysis relates the dominant visual tropes of the Cuban capital with more generic discourses regarding the tradition of utopian thought in the West and their embodiment in the image of the modern city. The diverse archival documents discussed throughout this thesis reflect recurrent themes that have characterised this tradition: the contemporary ideal of a
harmonious multicultural society; the romanticisation of the 'old city' as a visual reminder of our 'non-capitalist' past and the utopianism associated with the dichotomy between work and leisure and between the diurnal and the nocturnal. Most of these themes can be found as forming part of the discourse on the national in Cuba, also characterised by a deep utopianism.
The thesis examines the social and cultural history of Havana in order to analyse how the different documents have reflected, or even contributed, to the construction and problematisation of a Cuban national identity, while at the same time making testimony of the existence in the city of different cultural traditions. This has necessarily involved a reflection on the dynamics between the two main cultural traditions present in Havana: the Euro-Cuban and the Afro-Cuban. This thesis proposes that the cultural battles between the African, European and North American traditions in the city have been decisive in the modern re-fashioning of Havana as a museum-city, facilitating the predominantly nostalgic character of its most recent representations. This investigation also takes into account the crucial role of the city's spatial gendrification -
the position of women within the urban space - when describing Havana's utopian representations.
Finally, the interdisciplinary character of this thesis contributes to the analyses of the cultural history of cities as well as the relevance of the visual in the recreations of modern urban life and its relations to the narratives of the national
Academics’ perceptions regarding performance evaluations and the consequences for their professional and personal activity
Purpose – Improving and assuring the quality of higher education has become a key element of policy
agendas worldwide. To this end, a complete accountability system has been developed through various
evaluation procedures. Specifically, this study analyzes the perceptions of university teaching staff on the
impact of performance appraisal systems on their professional activity, health and personal lives.
Design/methodology/approach – The study adopted a nonexperimental descriptive and causalcomparative
design using a questionnaire that was completed by a sample of 2,183 Spanish teachers. The
data obtained were analyzed using descriptive statistics and comparisons of differences.
Findings – The results show that, according to teachers, the evaluation criteria undermine the quality of their
work by encouraging them to neglect teaching, increase scientific production and engage in unethical research
practices. Their views also emphasize the social and health-related consequences of an increasingly
competitive work climate, including increased stress levels. Finally, significant differences are observed
regarding gender, professional category and academic discipline, with women, junior faculty and social
sciences teachers expressing particularly strong views.
Originality/value – The originality of this study lies in the application of a method that contributes to the
international debate through a national perspective (Spain) that has so far received little attention.FEDER/Junta de Andalucia-Consejeria de Transformacion Economica, Industria, Conocimiento y Universidades/El Profesorado Novel en las Universidades Andaluzas B_SEJ-534-UGR20State Research AgencySpanish Government PID2019-105631GA-I00University of Granada INV-IGU199-2022Ministry of Universities (Spain) through the University Teacher Training Grants Programme FPU19/0094
Patterns of Social Activity Engagement Among Older Hispanics and Their Relationship to Sociodemographic and Health Variables
The purpose of this study was to examine patterns of social activity engagement in a sample of older Hispanics (Puerto Rican, Dominican, and other Hispanic) and determine whether these patterns differed significantly from the comparison non-Hispanic White group. This article also analyzes how ethnicity, sociodemographic, and health variables (health problems and depression) relate to each of the activity engagement patterns. The factor analysis of social activities from the Norbeck Social Support Questionnaire yielded three factors, which describe engagement in social activities as: children and relatives active, friends and activities active, and senior services active. The results from the regression analyses show that Hispanic ethnicity and education are positively associated with being more engaged in activities with children and relatives, whereas being male and especially a male living alone is inversely associated with this pattern. In addition, being friends and activities active shows positive association with education, the participant living alone, and experiencing more language inclusion; however, it is inversely associated with depression, age, being male, and number of health problems. Finally, engaging in activities offered by senior services is only significantly associated with increased age and the number of health problems. The interpretations of these findings, directions for future research, and implications for activity professionals/recreation therapists are also discussed

Proyecto de mejora de una explotación agraria en el término municipal de Granadilla de Abona para dedicarla a la producción del "higo pico" (Opuntia ficus-indica).
El interés detrás del cultivo de la Opuntia ficus-indica parte de la creciente necesidad de
agua. Se ha demostrado que esta especie, a diferencia de otros frutales, cuenta con una
potente capacidad de adaptación a distintos entornos y posee un gran potencial productivo
a pesar de su bajo consumo de agua y nutrientes.
En el presente proyecto, se estudia la viabilidad de implantar una explotación del cultivo
de la Opuntia ficus-indica adaptado a la zona de Granadilla de Abona, en el sur de la isla
de Tenerife. Para ello, se han realizado los cálculos correspondientes. El proyecto consiste
de un estudio y dimensionamiento de las instalaciones necesarias, así como de un estudio
de mercado y un análisis de viabilidad

Kainate Receptors Modulating Glutamate Release in the Cerebellum
Glutamate receptors of the kainate type (Kainate receptors, KARs), are mediators of ionotropic postsynaptic synaptic transmission, as well as presynaptic modulators of neurotransmitter release where they show both ionotropic and metabotropic actions regulating glutamate and γ-aminobutiric acid (GABA) release. The mechanisms underlying these modulatory roles are starting to be understood at some brain regions. Here we review the KARs roles and mechanisms involved in the modulation of glutamate release in the cerebellum at parallel fibers (PF)-Purkinje Cells (PuC) synapses. KARs activation mediate a biphasic effect on glutamate release at this synapse, with low kainate (KA) concentrations mediating a facilitation of glutamate release and higher KA concentrations mediating a depression of glutamate release. KA-mediated facilitation is prevented by antagonizing KARs, by inhibition of PKA or stimulation of adenylyl cyclase (AC), by blocking Ca2+ permeant KARs, by depleting intracellular Ca2+ stores and by blocking calmodulin. Thus, at cerebellar parallel fiber-Purkinje cell synapses, presynaptic KARs mediate glutamate release facilitation through Ca2+-calmodulin dependent activation of adenylyl cyclase/cAMP/protein kinase A signaling. KAR-mediated depression of glutamate release involves the AC/cAMP/PKA pathway as for facilitation but not Ca2+-calmodulin, being in this case AC activated by a Gi/o protein to mediate a depression of glutamate release

Procesos éticos globales para bibliotecarios: tecnocientíficos del siglo XXI en centros de patrimonio cultural
Tesis inédita de la Universidad Complutense de Madrid, Facultad de Filosofía, Departamento de Filosofía del Derecho, Moral y Política II, leída el 20-01-2016Esta investigación manifiesta la profesión del bibliotecario actual como un tecnocientífico del siglo XXI, que lleva a cabo una filosofía en la sociedad del conocimiento y la información (SCI). Presenta las obligaciones morales, inherentes a la profesión de quien trabaja para el patrimonio cultural de los pueblos y su idiosincrasia. Sus funciones enfocadas al trato con conocimiento ético, proveen a la sociedad moderna de nuevo conocimiento y servicios de excelencia. Los mismos requieren del profesional de la información, aplicar los recursos, la capacidad de evaluarlos, filtrarlos y seleccionarlos según los objetivos del centro, biblioteca o institución. El arte como recurso de valor ético se afianza en la mente y el cerebro con la filosofía, destacando los valores estéticos y éticos para su cuidado, el rol de los recursos en los Centros de Investigación de Patrimonio Cultural (CIPC) o Centros de Documentación e Investigación Artística (CDIA), así como su cuidado físico y seguridad. Se discurren las razones por la cuales el bibliotecario especializado debe atender el estudio de la conducta humana necesaria para el desarrollo y aplicación de la ética en CIPC, CDIA, entre otros tales como Centros de documentación e investigación CDI y por qué las teorías cognoscitivas tienen importancia. Se presentan sugerencias de un comportamiento ético que sugiere una filosofía como posible práctica...The study of this trial leads global ethical processes in library: technoscientific librarians of the 21st century. Its overall objective promoting philosophical reflection, analysis and placement of a code of ethics for the practice of a moral philosophy, global in ethical issues and not economical as we know the term “globalization” Issue and contemporary work of the profession is exercised on librarians, not for its instructional and management exists information and knowledge of human and physical resources of a library, but for the moral commitment that they have for this information and knowledge society globally. A method of deductive logic is used for the achievement of this dissertation divided into four (4) chapters and a code of ethics for a profession based on consciousness and intentionality, reflects to demonstrate experience, core, essential in the design of the ethics. The first chapter (1) is intended to present current philosophical thinking on practice for a society of information and knowledge centers for the librarian in this society of knowledge working with culture and patrimony from awareness using social, pictorial, technological art and its reflection in culture. Objective is discussed the value of epistemology of what is meant by ethics, technoscience, and techno-scientific this terms is use as a new name for librarians objective evolves terms and presents suggestions for renewal of the librarian profession. Outlines an ethics and a new concept: the techno-scientific that it manages or works in a center of documentation or artistic research. The responsibility of the human being, the professional librarian, a techno-scientific of the 21st century in this new century of information and awareness of evolution ethics, professional ethics, Technoetics, centers of artistic research and resources, ideas of philosophers, science hybrid evolutionary, a Moral Science? As a second chapter (2) The importance of the values is reflected in the designs of theories; artistic positivist, modern and latest theory of the evolution of art, illustrated for the first time in this paper to emphasize moral values represented in this fundamental means of expression in all cultures for perseverance of a global culture..Depto. de Filosofía y SociedadFac. de FilosofíaTRUEunpu
