Cinematic visions of Los Angeles: representations of identity and mobility in the cinematic city
No full textPhDAccounts of 'filmic' Los Angeles are often pessimistic, focusing upon the
geographies of segregation and exclusion evident in both the 'material' and
'cinematic' Los Angeles. In contrast to these more familiar readings, I propose a less
pessimistic and more nuanced picture of Los Angeles as cinematic city. I offer an
analysis of the cinematic city that, on the whole, shows a greater willingness to
deal with 'differences' and to examine the city's multiple geographies and
identities. I examine these multiple geographies with particular attention to themes
of mobility and identity which, I argue, are a central preoccupation of many Los
Angeles films. Moving beyond previous work on the 'geographies of film',
however, I contend that in order to address such themes in film analysis we need a
fuller engagement with film theory. Hence, in analyzing these themes I pay
particular attention to two issues. First, I give careful consideration to particular
film techniques, specifically, mise-en-scene, camera movement and editing, to
enable a more detailed analysis of the relationship between urban and cinematic
space. Second, I turn to the function of genre, not as'system of classification, but
as a mode of "cultural instrumentality", to examine what films do culturally.
Through the evidence of the film analysis I propose the potential of cinematic city
narratives to represent more fully the identities and mobilities of material Los
Angeles providing a revision, and in some cases, a re-imagining, of its overdetermined
image of social chaos and ethnic conflict

Optimisation of liquid rubber modified bitumen for road pavements and roofing applications
No full textPolymer Modified Bitumens (PMBs) are largely used for pavement and roofing membranes applications with Styrene-Butadiene-Styrene Block copolymer (SBS) playing a major role in both markets despite its constantly increasing price due to the rising demand for quality bitumen modifiers. On the other hand, there is an increasing trend of recycling end of life tyres generating Recycled Tyre Rubber (RTR) at affordable price. This investigation aims at engineering a modified bitumen with a combination of Liquid Rubber (LR), a homogeneous blend of 50-70% RTR pre-processed in combination with heavy oils, and a wax denominated Ethylene Bis Stearamide (EBS). In the first phase, the effect of LR and EBS was independently characterised and compared to PMBs. Next, the Response Surface Methodology (RSM) was used to predict the response of different combinations of LR and EBS in terms of low and high temperature properties and cost, to then be optimised targeting conventional and rheological properties of PMBs currently used in asphalt mixtures and roofing membranes in UK. As a result, an optimum combination of LR and EBS was found leading to a cost-effective modified bitumen comparable to PMBs. The work provided also analytical functions that could be of use in further design exercises.

Insurgent Learning: Confronting Neoliberal Assaults on Public Education in Los Angeles County in an Era of Accountability, 2000-2015
No full textInsurgent Learning examines neoliberal assaults on K-12 public education in Los Angeles County during an era of No Child Left Behind, from 2000-2015. In an era in which so-called “failing” public schools were accountable to rising academic expectations from the state, a movement to privatize public education, fueled through national, state, and local policies, enabled an outgrowth of corporate charter schools. Inspired by the author’s quest to understand the political landscape in education that led the non-profit, Parent Revolution, to organize in the city of Compton to invoke the California “parent trigger law,” Insurgent Learning reveals the policy architects behind the movement to privatize public schools in Los Angeles County. The dissertation expands beyond geo-political boundaries often defined by city limits and school district boundaries to present the region of South Los Angeles as a zone where structural violence is permissible and the school apparatus is a form of domestic warfare. Through an interdisciplinary analysis, the author relied on interviews, archival research, and her own auto-ethnographic experience to use a muxerista portraitist sensibility that captures competing visions for public education. Collectively, Insurgent Learning is an archive of insurgent knowledge that contributes to a genealogy of Black and Brown grassroots radicalism in the region of South Los Angeles as it centers communities at the forefront of efforts to reclaim and regenerate the democratic potential of public education
The rector of the hospital and his wife: two artificial mummies of the late 15th century from Siena (central Italy)
No full textTwo artificial mummies found in the hospital church of S. Maria della Scala in Siena (Tuscany, central Italy) and dated bock to the end of the 15th century, were examined. The mummies, in good state of preservation and still wearing their renaissance clothes, were identified as the rector of the hospital, named Salimbene Capacci, and his wife, Margherita Sozzini. Imaging studies, X-rays and CAT were performed. Autopsy made it possible to ascertain that the bodies had been eviscerated by a longitudinal cut from the neck to the pubis and that the thoracic and abdominal cavities had been filled with vegetable material. The pelvis was not eviscerated and the pelvic organs were conserved. The skull showed no traces of craniotomy or excerebration
Obtención de hidrolizados proteicos a partir de desechos de la industria pesquera
No full textEn este trabajo se obtuvieron hidrolizados proteicos de anchoíta Engraulis anchoita; utilizando enzimas recuperadas de desechos (cabezas y vísceras) de las siguientes especies pesqueras: el langostino Pleoticus muelleri, la merluza Merluccius hubbsi y la anchoíta E. anchoita. Para esto, se utilizaron las enzimas recuperadas al 1% (p/v) y se comparó su acción así como la calidad de los hidrolizados proteicos obtenidos, con dos elaborados con enzimas comerciales Alcalase 2.4 L-FG® y Neutrase 0.8L®. Con respecto al grado de hidrólisis alcanzado por los hidrolizados proteicos, los elaborados con enzimas recuperadas de la industria pesquera resultaron igualar y superar a los conseguidos con enzimas comerciales. También se analizó la capacidad de cada hidrolizado proteico de barrer el radical libre DPPH (EB), resultando todos los hidrolizados efectivos con valores que llegan al 80% de EB. Estos resultados se relacionan con la cantidad de ácidos grasos n-3 y n-6 encontrados en los mismos, los cuales ayudarían a incrementar el efecto barredor de radicales libre. Asimismo, la concentración proteica de todos los hidrolizados (80%), el bajo contenido de ácidos grasos trans y los contenidos de Nitrógeno Básico Volátil hacen que los mismos puedan ser aptos para el consumo humano y animal. En conclusión, la aplicación de los resultados de este estudio podrá beneficiar al sector pesquero argentino en cuanto a la valorización integral de las capturas y la utilización y puesta en valor de desechos provenientes del procesado de anchoita, langostino y merluza. Así la industria alimentaria tendrá a disposición nuevas enzimas y fuentes proteicas alternativas utilizables en diferentes procesos tecnológicos.Fil: Pereira, Nair de Los Angeles.

Energy efficiency in buildings analysis through thermal simulation of buildings and advanced interpolation of meteorological data
No full textEl presente proyecto de tesis doctoral se centra en completar la falta de estudios científicos
sobre la interpolación de datos meteorológicos para calibrar las simulaciones térmicas de
edificios. Uno de los aspectos principales es determinar cómo los errores en la obtención
de datos meteorológicos se transmiten a las demandas térmicas de los edificios obtenidas
a través de simulaciones térmicas transitorias, consideradas un buen método para predecir
el consumo energético de los edificios.
Esta tesis doctoral evalúa el desempeño de diferentes técnicas de interpolación y su
aplicación a ubicaciones donde no existen estaciones meteorológicas.
Para el desarrollo del estudio se emplean las redes de estaciones meteorológicas de AEMET
(Agencia Estatal de Meteorología) y MeteoGalicia como fuente de datos meteorológicos,
se han seleccionado las 6 variables meteorológicas recogidas en el manual ASHRAE,
Guideline 14-2002: temperatura, presión, radiación global, humedad relativa, velocidad del
viento y dirección del viento, y se utilizan diferentes tipologías edificatorias para determinar
cómo se transmiten los errores a las demandas térmicas de distintos tipos de edificios
seleccionados (edificio terciario, vivienda unifamiliar y edificio multivivienda en cada uno de
los 3 artículos científicos publicados).
En el primer artículo, el edificio terciario correspondiente a la Biblioteca de Ciencias del Mar
de la Universidad de Vigo, se estudió utilizando los datos de la estación meteorológica
situada en el mismo campus de la Universidad de Vigo, a escasos 250m, comparando los
valores obtenidos a través de la simulación transitoria con los calculados con la estación
meteorológica más cercana, en este caso la del aeropuerto de Vigo, a unos 7,5 km, y
comparándolos también con los datos interpolados de toda la red a nivel gallego de
MeteoGalicia: 3 conjuntos de datos derivados de 3 tipos de interpolaciones mediante
kriging: Ordinary Kriging (OK), Universal Kriging (UK) con 3 predictores (longitud, latitud y
altura) y Universal Kriging con 4 predictores (longitud, latitud, altura y distancia a costa).
En el segundo artículo, una vivienda unifamiliar se “desplazó” sucesivamente por 18
ubicaciones de la provincia de Pontevedra, estudiando su respuesta a las interpolaciones
de datos meteorológicos mediante cuatro métodos: Ordinary Kriging, Universal Kriging con
tres predictores (longitud, latitud y altura), Universal Kriging con cuatro predictores
(longitud, latitud, altura y distancia a costa)y Thin Plate Splines (TPS) y enfrentándolos a los
datos de la estación meteorológica más cercana (Nearest Neighbourhood - NN) en cada
una de las ubicaciones. Estudiándose los resultados tanto de las interpolaciones de datos
meteorológicos como de las simulaciones térmicas transitorias, mediante tablas de
resultados.
En el tercer artículo el edificio seleccionado es un edificio multivivienda de 8 plantas.
Moviéndolo sucesivamente por 70 ubicaciones en Galicia, que son las ubicaciones donde la red meteorológica de MeteoGalicia dispone de estaciones donde están disponibles datos
de las 6 variables meteorológicas estudiadas. En este tercer artículo se compararon los
resultados obtenidos utilizando la estación meteorológica más cercana (NN) con el método
de interpolación mediante TPS, y los datos obtenidos, tanto en las interpolaciones de
variables meteorológicas como de las simulaciones térmicas transitorias, se visualizaron y
compararon mediante tecnología de mapeo SIG (Sistemas de Información Geográfica), en
este caso mediante el software QGIS. Se empleó esta tecnología ya que, al tratarse en este
caso de 70 ubicaciones, el manejo de tablas de datos se complica debido a su extensión.
Los datos meteorológicos son críticos para una simulación térmica adecuada, ya que
constituyen las condiciones de contorno del edificio y no siempre están disponibles en la
ubicación exacta del edificio y, por lo tanto, los datos de la estación meteorológica más
cercana, que se pueden encontrar a kilómetros de la ubicación en estudio, se utilizan de
forma extendida.
Para las simulaciones térmicas se emplea el software TRNSYS (Transient System Simulation
Tool) como motor de cálculo de las demandas térmicas de los edificios elegidos. La eficacia
de las distintas técnicas de interpolación se evalúa durante un año sobre una base de datos
horaria.
Los resultados de la comparación de los diferentes métodos de interpolación muestran que
no todas las variables climáticas tienen la misma influencia en los resultados de las
simulaciones térmicas, y que mediante la interpolación de datos meteorológicos se
disminuyen los errores en la obtención de las demandas térmicas de las tipologías
edificatorias analizadas mediante simulación térmica transitoria, frente a las técnicas
utilizadas actualmente de forma más extendida.Este proxecto de tese de doutoramento baséase na falta de estudos científicos sobre a interpolación de datos meteorolóxicos para calibrar simulacións térmicas de edificios. Un dos principais aspectos é determinar como erros na obtención de datos meteorolóxicos son transmitidos ás esixencias térmicas de edificios obtidos a través de simulacións térmicas transitorias, considerado un bo método para prever o consumo de enerxía dos edificios.
Esta tese avalía o rendemento de diferentes técnicas de interpolación ea súa aplicación en lugares onde non hai estacións meteorolóxicas.
Para este estudio se empregan as redes de estacións meteorolóxicas AEMET (Axencia Estatal de Meteoroloxía) e MeteoGalicia como fonte de datos meteorolóxicos, e diferentes tipos de construción son usados para determinar como os erros son transmitidos ás esixencias térmicas de distintos tipos de edificios seleccionado.
Os datos meteorolóxicos son fundamentais para a simulación térmica axeitada, pois constitúen as condicións de contorno do edificio e non sempre están dispoñibles na localización exacta do edificio e, polo tanto, os datos da estación meteorolóxica máis próxima, que se pode atopar en quilómetros do estudo de localización que utilizaban forma estendida.
O software TRNSYS é usado como un motor de cálculo das esixencias térmicas dos edificios escollidos. A eficacia de diferentes técnicas de interpolación para un ano é valorada en base a datos en tempo.
Os resultados da comparación de distintos métodos de interpolación demostrar que non todas as variables meteorolóxicas teñen a mesma influencia sobre os resultados das simulacións térmicas, e interpolando erros de datos meteorolóxicos son reducidos na obtención de demandas térmicas tipo de construción analizados por simulación térmica transiente, en comparación coas técnicas correntemente utilizados máis amplamente.The present dissertation project is based on the lack of scientific studies on the interpolation of meteorological data to calibrate the thermal simulations of buildings. One of the main aspects is to determine how errors in obtaining meteorological data are transmitted to the thermal demands of buildings obtained through transient thermal simulations, considered a good method to predict the energy consumption of buildings.
This doctoral thesis evaluates the performance of different interpolation techniques and their application to locations where there are no meteorological stations.
For the development of the study the networks of meteorological stations of AEMET (Meteorological Agency of State) and METEOGALICIA as meteorological data source are used, and different types of buildings are used to determine how the errors are transmitted to the thermal demands of different types of buildings Selected.
The meteorological data are critical for adequate thermal simulation because they constitute the boundary conditions of the building and are not always available in the exact location of the building and therefore the data of the nearest meteorological station that can be found In kilometers of the study location, are used extensively.
For thermal simulations, the TRNSYS (Transient System Simulation Tool) software is used as the calculation engine for the thermal demands of the chosen buildings. The efficiency of the different interpolation techniques is evaluated over a year on an hourly basis.
The results of the comparison of the different interpolation methods show that not all climatic variables have the same influence on the results of the thermal simulations, and that through the interpolation of meteorological data the errors in obtaining the thermal demands of The building typologies analyzed by means of transient thermal simulation, compared to the techniques currently used in a more widespread way.Ministerio de Economía y Competitividad de España | ENE2015-65999-C2-1-RGobierno de España | IDI-201505050
Spatial practices of Soul Rebel Radio in Los Angeles' third world left
No full textThe study examines the results of the case study analysis of Soul Rebel Radio and the use of space and location by the Chican@ community in the Third World Left in Los Angeles. The term Chican@ is used interchangeably for Chicanas and Chicanos, and the community makes up a part of what the study identifies as the Third World Left in Los Angeles. The concept of the Third World Left in Los Angeles is used to refer to non-majority groups instead of using the term "minority," and it is used interchangeably with Chican@s and other communities. Soul Rebel Radio transforms the sound of KPFK and redefines the meaning of Chican@ radio to produce cultural citizenship. The collective seizes the listener sponsored community space of the Pacifica Network and reclaims ownership of the public airwaves. The study demonstrates that Chican@s and the Third World Left in Los Angeles challenge the mainstream productions of media, negotiate the limits of the structure and format of radio, and create alternative spaces for themselves and the community. By producing alternative media, Soul Rebel Radio builds community, develops the self-identity of the collective members, and finds new and young voices. Soul Rebel Radio does this through an engagement with radio and a spatial practice that is collective, vibrant, original, and based on the experiences of the Chican@s and members of the Third World Left in Los Angeles. KPFK forms part of the Pacifica Network, the oldest public radio association in the United States, and it remains the only independent media outlet in Los Angeles. "Independent Media" is defined as listener sponsored radio, and the program can be accessed at KPFK 90.7 FM in Los Angeles and at www.kpfk.org. According to the KPFK website, the Mission of the Pacifica Network is to "promote full distribution of public information and to employ such varied sources in public presentation of accurate, objective, and comprehensive news on all matters vitally affecting the community." By not relying on outside funding, the station and the show are free to present a number of different topics to the community. Soul Rebel Radio liberated a space for youth in Los Angeles, and placed themselves at the core of the narrative to create media that is culturally, politically, socially, historically, and aesthetically relevant. By employing an auto-ethnographic method of analysis, the author utilizes qualitative and quantitative studies of media and other examples of radio to demonstrate that Soul Rebel Radio creates culturally relevant, politically active, and reconceptualized concepts of space, media, audience, community, and radio production in Los Angeles. The author demonstrates that youth need to have spaces to exercise their creativity in order to develop a powerful voice, and the data utilized in this study is drawn from original programs created by Soul Rebel Radio. Interviews with members of the collective substantiate my claim that participation in the program was beneficial to individuals and the community. My goal for this study is to demonstrate the significance of the new knowledge created by radio programs produced by Chican@s and other youth in Los Angeles. The experimental program does not adhere to traditional radio formats, and Chapter One details how Soul Rebel Radio presents a challenge to mainstream media. The Third World Left in Los Angeles represents a challenge to social hierarchy while helping contextualize the space occupied by the community that makes up most of the Soul Rebel Radio collective. The Intersection of Soul and Revolution explains one of the goals of the group as the expansion of the definition of uprising to embrace all forms of dissent including spiritual challenges, philosophical differences, and revolutionary nationalism that could benefit the community. Another important contribution in this chapter involves Soul Rebel Radio and Gender Equity. The responsibility for the collective is to ensure the participation of women in every aspect of the program, develop new voices, and unlearn gender norms that the men in the group can take for granted. Soul Rebel Radio created the Revolution in Prime Time as an effort to demonstrate how media shuns the actions of poor, minority, and Chican@ youth in particular, and we confront this by seeking out individuals to participate in the production of collective forms of knowledge. Finally, the section called Youth Radio in California is a case study of the Oakland organization that most resembles the focus on youth produced media established autonomously by the Soul Rebel Radio collective in Los Angeles. Chapter Two expands on the original work produced by Soul Rebel Radio proving that when given an opportunity, youth create original programs that help challenge the mainstream representation of Chican@s and other communities in what Laura Pulido defines as the Third World Left. The purpose of Soul Rebel Radio is to highlight, profile, and present young people on the air, and the section highlights shows related to the core concept of youth. Another key factor for the group is the inclusion of women and a focus on gender equity, and the section presents programs related to historical challenges to patriarchy led by the young women in the collective. One of the most pressing issues for Soul Rebel Radio is the environment, and the Kilo Watts and Tiny Energy Segment provides a platform to advocate for sustainability and respect for Mother Earth. In the seven plus years that Soul Rebel Radio has aired, the collective has profiled a number of specific years and individuals. Parts of the chapter demonstrate how the program connects historical moments and central figures that transform our reality. Perhaps Soul Rebel Radio's best radio productions revolve around abstract concepts, and the last section of the chapter displays the power of youth to employ creativity and present critical media capable of educating and entertaining the community. The purpose of the program is to present youth on the air, but the goal is to recruit young people to help craft social justice. Soul Rebel Radio, like Chican@ Studies, is a multi-disciplined approach to understanding the contradictions in society related to race, class, gender, and sexual orientation. The final chapter of the study includes interviews with the individuals who participated in the program throughout the years. In general, most members of the collective benefited from the development of their voice with Soul Rebel Radio. Each member volunteered and participated fully in the production of original content, and Soul Rebel Radio provided the stage for Chican@s and other members of the Third World Left to take ownership of the airwaves and create a space for youth on the radio. The young people who participated took their learned skills found at the intersection of race, class and gender into the community to effect change. Soul Rebel Radio allowed individuals to speak directly to the community and in that way help challenge the mainstream images of Chican@s and other members of the Third World Left that dominate the mainstream television and news media. Even progressive radio stations like KPFK rarely make concerted efforts to create spaces for youth or people of color, and we changed that. Thus, by working as a collective with other members of the Third World Left in Los Angeles, Soul Rebel Radio is able to present each theme as completely as possible. In short, Soul Rebel Radio provides young people in Los Angeles an opportunity to express ideas and find their voice while producing a monthly show based on a specific theme that is politically relevant to the community. To date, more than 70 original programs in 7 plus years of production have been created by in excess of 50 members of the Soul Rebel Radio collective.Includes bibliographical references (pages 98-99)California State University, Northridge.
