Deb, Sagarmay. "Content-based image retrieval based on emergence index." University of Southern Queensland, Faculty of Sciences, 2003. http://eprints.usq.edu.au/archive/00001420/.
Full textAbstract:
Emergence is a phenomenon where we study the implicit or hidden meaning of an image. We introduce this concept in image database access and retrieval of images using his as an index for retrieval. This would give an entirely different search outcome than ordinary search where emergence is not considered, as consideration of hidden meanings could change the index of search. A feature of an image, which is not explicit would be emergent feature if it can be made explicit. There are three types of emergence: computational emergence, thermodynamic emergence and emergence relative to a model. In computational emergence, it is assumed computational interactions can generate different features or behaviors. This is one of the approaches in the field of artificial life. Thermodynamic emergence is of the view that new stable features or behaviors can arise from equilibrium through the use of thermodynamic theory. In emergence relative to a model, deviation of the behavior from the original model gives rise to emergence. We would use this latter view in our work. Two classes of shape emergence have been identified: embedded shape emergence and illusory shape emergence. In embedded shape emergence all the emergent shapes can be identified by set theory procedures on the original shape under consideration. For example, in a set S= {a,b,c,d,e}, we can find subsets like S1={a,b,c}, S2={c,d,e}, S3={a,c,e} and so on. But in illusory shape emergence, where contours defining a shape are perceived even though no contours are physically present, this kind of set theory procedures are not enough and more effective procedures have to be applied to find these hidden shapes. These procedures could be based on geometrical, topological or dimensional studies of the original shape. Content-based Image Retrieval (CBIR) techniques, so far developed, concentrated on only explicit meanings of an image. But more meanings could be extracted when we consider the implicit meanings of the same image. To find out the implicit meanings, we first destroy the shape of the original image which gives rise to unstructured image. Then we process the unstructured image to bring out the new emergent image. We discuss emergence, calculation of emergence index and accessing multimedia databases using emergence index in this dissertation. To calculate emergence index in the access of multimedia databases, we take an input image and study the emergence phenomenon of it. Also we study the emergence phenomenon of the images of the database. Both input image and images of database would give rise to more meanings because of emergence as we explained earlier. Based on the new meanings, wherever there would be a match between input image and images of database, we would pick that record up for selection. We defined emergence index as EI = f(D,F,V,C,E) where D stands for domain of the database, F for features of the image, V for various variables that define the image, C for constraints which represent the image and E for emergence phenomenon. We calculate these five variables to get emergence index for each image of the database. Also we calculate these five variables for input image as well. We talk about global aspects of features. It means features of the entire image. Examples are area, perimeter or rectangles, triangles. In some searches, to consider the global features could be advantageous in that a symmetry with the input image could be obtained on the basis of global features only. But as is clearly the case, to consider global features could overlook the individual objects that constitute the image as a whole. In the kind of searches we propose, we take into account the global features of the image of the database while considering in detail local features. Various objects that lie within an image constitute local features. In our example, there are three objects in the image, namely, a lake and two houses. Studying the features of these three objects would add to studying the features of the image globally. We took the example of a geographic location in the thesis and then showed how destruction of original image is done and further processing of the unstructured image gives new emergent image. Partial implementation of this concept is also presented at the end. In implementation, we consider the retrieval of image globally. We do not consider break-up of image into multiple objects which is left for future research.

Full textAbstract:
Tobacco seed performance is traditionally measured as percentage
germination at 14 d under controlled laboratory conditions. However, under
greenhouse conditions, seed lots with equal 14-d germination may exhibit
substantial differences in uniformity of early seedling growth and spiral root
incidence that impact the number of usable transplants. A seedling performance
index (SPI) was developed to quantitatively describe greenhouse tobacco seedling
performance. The 14-d emergence, relative leaf area uniformity, and seedling leaf
area determined by computer image analysis were used to calculate the index.
Greenhouse tobacco seed trials demonstrated that seed with the Rickard pellet had
higher emergence, but the higher spiral root incidence associated with the Rickard
pellet lowered the SPI compared to the Cross Creek pellet. Primed seed lots of
flue-cured cultivars (NC 72 and NC 71) had a significantly higher SPI than the
nonprimed seed lots at one location but not at a second location. Seed lots sown
in Premier Pro-Mix TA commercial medium had a higher spiral root incidence,
which resulted in a lower SPI compared to Carolina Choice, Carolina Gold, and
Sunshine LP5 commercial media. The index quantitatively determined
differences in seedling performance under greenhouse conditions not reflected by
standard germination tests. Significant differences in the SPI were observed
among seed lots with certified 90% germination. The SPI is a simple method to
describe seedling performance because the data used to calculate the SPI is
obtained from one seed tray image. In contrast, frequent counting and seedling
evaluations are involved with standard germination and vigor tests.Master of Science

Full textAbstract:
The social transformations in the South Levantine Neolithic show two basic tendencies: 1) complex social structures are replaced by less complex ones, before more complex social structures develop; and 2) most likely connected to that: heterarchical and hierarchical patterns are linked together in varying ways; the more needs for social regulation appear, the more heterarchical elements trigger corporate, hierarchical and central structures, and new sedentary types of conflict occur. The development of family and communal life modes moved as shifting waves through the ecozones of the southern Levant: core household structures (MPPNB) are replaced by corporate extended families households (LPPNB) which then again are replaced by core household structures (FPPNB-PNA-B); heterarchical communities (PPNA) get replaced by hierarchical (MPPNB-LPPNB) communities, before pastoral-heterarchical communities develop (FPPNB-PNA-B) and exist together with the hierarchical permanent settlements of the FPPNB-PNA-B. The qualities and momentum of this general development may differ according to regional ecological conditions, including reversible and conservative regional developments.Las transformaciones sociales del Neolítico en el Levante meridional denotan dos tendencias básicas: 1) las estructuras sociales complejas son reemplazadas por otras de características menos elaboradas en una etapa previa al despliegue de estructuras sociales más complejas, y 2) probablemente en forma paralela, se entrelazan principios heterárquicos y jerárquicos del orden social en proporciones cambiantes. Con la creciente demanda de una regulación de los elementos heterárquicos, estos desaparecen para ser sustituidos por estructuras jerárquicas corporativas y centrales, por lo que aparecen nuevas formas sedentarias de conflicto. El desarrollo de las formas de vida familiares y comunales atravesó, a manera de olas consecutivas, los diferentes paisajes del Levante meridional: estructuras familiares nucleares (en el PPNB Medio) fueron reemplazadas por estructuras familiares extensas corporativas (PPNB Tardío) y volvieron, luego, a su estado inicial (PPNB Final a PNA-B). Las comunidades heterárquicas (PPNA) se convirtieron en jerárquicas (PPNB Medio a PPNB Tardío) antes del surgimiento de comunidades heterárquicas pastoriles (PPNB Final a PNA-B) que coexistieron, en forma paralela, con asentamientos jerárquicos permanentes (PPNB Final a PNA-B). Las cualidades y la velocidad de este proceso general dependen, en forma especial, de factores ecológicos regionales e incluyen desarrollos regionales de carácter tanto reversible como conservador.

Full textAbstract:
This article analyzes the technocracy emergence in social sector, through the study of the Ministry of Development and Social Inclusion case, created in 2011 in response to one of the essential themes of Ollanta Humala’s electoral campaign: social inclusion. This paper aims to determine which factors led to the establishment of a technocracy linked to social policy in a country where it has been traditionally linked to political usage and patronage. There are three factors that explain the positioning of a technocracy in this ministry addressed throughout the article. On one hand, there was the presence of a consensus about the need for a technical management of this sector in the search of generating legitimacy and autonomy. On the other hand, it happened to be a favorable political environment characterized by a wide political support from the government. Finally, the wide discretion of the technical team in the design of MIDIS and during formation of the first ministerial body of bureaucrats allowed the emergence of a technocratic institution. To this end, this article describes development of the stages of the creation of the institution, design, approval and implementation and shows a corroboration of the technocratic profile of the initial top management team of this ministry.El presente artículo analiza el surgimiento de una tecnocracia en un sector social, a través del caso del Ministerio de Desarrollo e Inclusión Social, creado en el 2011 en respuesta a uno de los ejes centrales de la campaña electoral de Ollanta Humala: la inclusión social. Este texto busca determinar qué factores permitieron el establecimiento de una tecnocracia vinculada a la política social en un país donde esta ha estado tradicionalmente vinculada a un manejo político y clientelar. A lo largo del artículo, se abordan tres factores que explican el posicionamiento de una tecnocracia en este ministerio. Por un lado, existió un consenso sobre la necesidad del manejo técnico de este sector en la búsqueda de generar legitimidad y autonomía. Por otro lado, se dio un entorno político favorable caracterizado por un vasto respaldo político del gobierno. Por último, el amplio margen de decisión de los técnicos en el diseño del MIDIS y en la conformación del primer cuerpo ministerial permite el surgimiento de una institución de carácter tecnocrático. Para ello, esta investigación describe el desarrollo de las etapas de creación de esta institución, de diseño, aprobación e implementación, así como presenta una corroboración del perfil tecnocrático del equipo inicial de alta dirección de este ministerio.

Full textAbstract:
We examine the emergence of the Neolithic in the Southwest United States by focusing on the Mesa Verde region and the research we have conducted there as a part of the Village Ecodynamics Project. The Mesa Verde region has many characteristics that make it an ideal place to study the emergence of the Neolithic. The region has about 20.000 recorded archaeological sites. These sites are highly visible because there has been relatively little erosion or deposition. The arid climate has resulted in remarkable preservation, and tree-ring dating provides precise chronological resolution. Tree rings also allow annual reconstructions of temperature and precipitation. Finally, Pueblo Indians continue to live in New Mexico and Arizona today, and their oral traditions can be combined with archaeological information to provide a more complete and inclusive reconstruction of the Pueblo past. We examine the lengthy occupation of the Mesa Verde region to better understand the relationship between the following key elements of the Neolithic: the introduction of domesticated food production, the causes and consequences of population growth, the effects of climate change, the intensification of the warfare, the degree of sedentism and frequency of population movement, the formation of villages, and the emergence of complex social and political organization.En el presente trabajo se analiza el surgimiento del Neolítico en el Suroeste de los Estados Unidos sobre la base de la región de Mesa Verde y las investigaciones que los autores han dirigido como parte del Village Ecodynamics Project (VEP). Esta región tiene muchas características que la hacen ideal para estudiar el surgimiento del Neolítico. Tiene cerca de 20.000 sitios arqueológicos registrados que son bastante visibles debido a la relativamente poca erosión y los escasos procesos de deposición. El clima árido ha motivado una conservación notable y el fechado dendrocronológico ha proporcionado una definición cronológica precisa. Las series de anillos de los árboles también han permitido reconstrucciones anuales de la temperatura y las precipitaciones. Por último, los indios pueblo aún viven en New Mexico y Arizona en la actualidad, y sus tradiciones orales pueden ser combinadas con información arqueológica para brindar una reconstrucción más completa, inclusive, del pasado de estos grupos humanos. Se examina la larga ocupación de la región de Mesa Verde para entender mejor la relación entre los siguientes elementos clave del Neolítico: la introducción de una producción de alimentos domesticados, las causas y consecuencias del crecimiento poblacional, los efectos del cambio climático, la intensificación de la guerra, el grado de sedentarismo y la frecuencia del movimiento de poblaciones, la formación de aldeas y, por último, el surgimiento de la organización social y política compleja.

Full textAbstract:
In this paper we discuss the diffusionist implications derived from centre-periphery relationships and the establishment of dependency links between western valley and circunpuna societies within the nuclear zone of the central and southern highlands during the Early and Middle Formative periods in northern Chile (1500 BC up to AD 400). By analyzing two complex settlements, Tulán-54 (located 3000 meters above sea level) and Caserones-1 (900 meters above sea level), we have observed that there has been an over-interpretation of foreign contributions in explaining the rise of sedentism that is associated with Formative Period developments. The identification of Archaic and Formative period components at the Tarapacá and Tulán loci supports an autochthonous development, which suggests the rise of local complex societies with early multidirectional links within a framework of highly diversified Formative responses in the Central-South Andean area.En el presente trabajo se discuten las implicancias difusionistas derivadas del enfoque de las relaciones centro-periferia y la tendencia a establecer vínculos de dependencia entre las sociedades de las subáreas de los Valles Occidentales y la Circunpuna respecto de las tierras altas nucleares durante los periodos Formativo Temprano y Medio del norte de Chile (1500 a.C. a 400 d.C.). Mediante el análisis de dos asentamientos complejos, Tulán-54 (3000 metros sobre el nivel del mar) y Caserones-1 (900 metros sobre el nivel del mar), se advierte que ha existido una sobrevaloración de los aportes alóctonos para explicar el surgimiento del sedentarismo asociado a prácticas formativas. La identificación de componentes arcaico-formativos transicionales sustenta la tesis autoctonista, que valoriza, más bien, el surgimiento de tempranas sociedades complejas regionales que establecieron relaciones de interacción paritaria y multidireccional en el área centro-sur andina.

This study seeks to evaluate an electronic triage system based on machine learning models that can predict the patients emergency severity index (ESI). Methods: A dataset containing 560 486 patients triage data was investigated.Three different machine learning models was tested and evaluated. A crossvalidation table and a confusion matrix was conducted from each of the models. The precision rate, recall rate and f1-score were calculated and reported. Result: The Gradient Boosting model returned an accuracy rate of 68%. The random forest model returned an accuracy rate of 66%. The Gaussian Naive Bayesmodel returned an accuracy rate of 25%. Conclusion: The model that best predicted the ESI-level is the GradientBoosting model. Further testing is needed with better computational power since we could not train our model with the whole dataset.Syfte: Akutmottagningen i USA förlitar sig kraftigt på en subjektiv värdering av patienter.

Previous issue date: 2011-03-28The study aimed to evaluate the cold tolerance of four rice cultivars under stress conditions (13-18°C) in stages S0-V3 and check the season effect of irrigation suppression on the quality of rice seeds from the cultivars BRS Atalanta, BRS Querência and BRS 7 Taim. The study consisted on two experiments performed independently. In the first experiment, it was evaluated the cold tolerance of seeds of the cultivars Brilhante, BRS SCS Tio Taka, BRS Querência and BRS7 Taim under stress conditions (13-18°C) during early development (S0-S3). The evaluative parameters were: speed index of total emergence, speed index of emergence of the stage V1, V2 and V3, index of cold tolerance (ICT), index of susceptibility to cold (ISC), index of cold intensity (ICI), geometric average (GA), chlorophyll content (CC) and seedling length (SL). The Brilhante cultivar showed tolerance to the temperature of 13-18°C, measured by the speed index of total emergence, speed index of vegetative stages, tolerance index, geometric average, chlorophyll content and seedling length at the initial development. In the second experiment, it was used seeds from the cultivars BRS Atalanta, BRS Querência and BRS 7 Taim and it was conducted in two stages. In the first stage, it was made the irrigation suppression in four seasons: Season 1: stage of panicle exsertion (R3) Season 2: stage of milky grain (R6) Season 3: stage of pasty grain (R7), and Season 4: physiological maturity (R9). In the second stage, it was performed the analysis of seed quality harvested for each treatment, through the germination test, cold test, accelerated aging, electrical conductivity, weight of a thousand seeds and seed health. It was not possible to assess the season of irrigation suppression, in the stages of panicle exsertion, milky grain, pasty grain and physiological maturity due to the high rainfall occurred throughout the reproductive phase of rice seeds of the three cultivars evaluated. The high rainfall combined with high temperature were the main factors that favored the incidence of fungus from the genus Aspergillus sp., Penicillium sp., Fusarium sp., and Bipolaris sp. on the seeds of the cultivars in study.
O trabalho objetivou avaliar a tolerância ao frio de quatro cultivares de arroz sob condições de estresse (13-18ºC) nos estádios S0-V3 e verificar o efeito da época da supressão da irrigação na qualidade das sementes de arroz das cultivares BRS Atalanta, BRS Querência e BRS 7 Taim. O estudo constitui-se de dois experimentos realizados independentemente. No primeiro experimento, avaliou-se a tolerância ao frio das sementes das cultivares Brilhante, BRS SCS Tio Taka, BRS Querência e BRS7 Taim em condições estresse (13-18ºC) durante o desenvolvimento inicial (S0-V3). Os parâmetros avaliativos utilizados foram: índice de velocidade de emergência total, índice de velocidade de emergência do estádio V1, V2 e V3, índice de tolerância ao frio (ITF), índice de suscetibilidade ao frio (ISF), índice de intensidade ao frio (IIT), média geométrica (MG), teor de clorofila (TC) e comprimento de plântula (CP). A cultivar Brilhante apresentou tolerância à temperatura 13-18°C, avaliado pelo índice de velocidade de emergência total, índice de velocidade dos estádios vegetativos, índice de tolerância, média geométrica, teor de clorofila e comprimento de plântula no desenvolvimento inicial. No segundo experimento, utilizou-se sementes das cultivares BRS Atalanta, BRS Querência e BRS 7 Taim e foi realizado em duas etapas. Na primeira etapa, realizou-se a supressão da irrigação em quatro épocas: Época 1: estádio de exerção da panícula (R3); Época 2: estádio de grão leitoso (R6); Época 3: estádio de grão pastoso (R7) e, Época 4: maturidade fisiológica (R9). Na segunda etapa, efetuaram-se as análises de qualidade das sementes colhidas para cada tratamento, através dos testes de germinação, frio, envelhecimento acelerado, condutividade elétrica, peso de mil sementes e sanidade. Não foi possível avaliar a época da supressão da irrigação, nos estádios de exerção da panícula, grão leitoso, grão pastoso e maturidade fisiológica em função da elevada precipitação pluvial ocorrida durante toda a fase reprodutiva das sementes de arroz das três cultivares avaliadas. A elevada precipitação pluvial aliada à alta temperatura foram os principais fatores que favoreceram a incidência dos fungos dos gêneros Aspergillus sp., Penicillium sp., Fusarium sp., e Bipolaris sp. sobre as sementes das cultivares em estudo.

Full textAbstract:
Lima, capital of Perú, together with El Callao configure a large urban agglomeration of near nine million people that makes one third of the total Peruvian population. It is characterized by huge social and spatial inequalities and serious governance and urban management problems; and it is the siege of the national public establishments, the administrations, banks and big enterprises, which results in the concentration of half of the Peruvian economy. From this perspective, any perturbation of Lima by a disaster might affect not only the city and her inhabitants but also the Peruvian territory as a whole. The purpose of this paper is to argument the need to develop a strictly geographic focus in the scientific research on the management of emergency situations. This demonstration is based on a study made by PACIVUR about the resources available to attend the disasters in Lima and El Callao, under the hypothesis of the occurrence of a great earthquake followed by a tsunami.Lima, capital del Perú, conforma con el Callao una extensa aglomeración urbana que registra cerca de nueve millones de habitantes o sea un tercio de la población peruana. Caracterizada por grandes desigualdades sociales y espaciales y agudos problemas de gobernabilidad y gestión urbana, la urbe centraliza los poderes públicos nacionales, las administraciones, los bancos y sedesde grandes empresas lo que resulta en la concentración de la mitad de la economía peruana en la aglomeración capital. Desde esta perspectiva, la perturbación de Lima por un desastre afectaríano solamente la ciudad y sus habitantes sino también el territorio peruano en su conjunto. El propósito de este texto es argumentar la necesidad de desarrollar un enfoque específicamente geográfico en las investigaciones científicas sobre el manejo de las situaciones de emergencia. Esta demostración se apoya en un estudio que se hizo sobre los recursos para la atención de desastre en Lima y Callao, en la hipótesis de ocurrencia de un sismo de gran magnitud acompañado de un tsunami.

Full textAbstract:
This thesis considers applications of machine learning techniques in hospital emergency readmission and comorbidity risk problems, using healthcare administrative data. The aim is to introduce generic and robust solution approaches that can be applied to different healthcare settings. Existing solution methods and techniques of predictive risk modelling of hospital emergency readmission and comorbidity risk modelling are reviewed. Several modelling approaches, including Logistic Regression, Bayes Point Machine, Random Forest and Deep Neural Network are considered. Firstly, a framework is proposed for pre-processing hospital administrative data, including data preparation, feature generation and feature selection. Then, the Ensemble Risk Modelling of Hospital Readmission (ERMER) is presented, which is a generative ensemble risk model of hospital readmission model. After that, the Temporal-Comorbidity Adjusted Risk of Emergency Readmission (T-CARER) is presented for identifying very sick comorbid patients. A Random Forest and a Deep Neural Network are used to model risks of temporal comorbidity, operations and complications of patients using the T-CARER. The computational results and benchmarking are presented using real data from Hospital Episode Statistics (HES) with several samples across a ten-year period. The models select features from a large pool of generated features, add temporal dimensions into the models and provide highly accurate and precise models of problems with complex structures. The performances of all the models have been evaluated across different timeframes, sub-populations and samples, as well as previous models.

Full textAbstract:
Hospitals stand to lose millions of dollars in revenue due to patients who leave without treatment (LWT). Grounded in queueing theory, the purpose of this correlational study was to examine the relationship between daily arrivals, daily staffing, triage time, emergency severity index (ESI), rooming time, door-to-provider time (DTPT), and LWT rates. The target population comprised patients who visited a Connecticut emergency room between October 1, 2017, and May 31, 2018. Archival records (N = 154) were analyzed using multiple linear regression analysis. The results of the multiple linear regression were statistically significant, with F(9,144) = 2902.49, p < .001, and R2 = 0.99, indicating 99% of the variation in LWT was accounted for by the predictor variables. ESI levels were the only variables making a significant contribution to the regression model. The implications for positive social change include the potential for patients to experience increased satisfaction due to the high quality of care and overall improvement in public health outcomes. Hospital leaders might use the information from this study to mitigate LWT rates and modify or manage staffing levels, time that patients must wait for triage, room placement, and DTPT to decrease the rate of LWT in the emergency room.

Full textAbstract:
In this paper, I discuss early complexity in the southern Lake Titicaca Basin of the Bolivian Andes. I examine a regional landscape of multi-community formations that emerged during the Late Formative Period (100 BC-AD 500). I suggest that during the Late Formative in the southern Lake Titicaca basin, the establishment of Khonkho Wankane and other disembedded centers, played an important role in the social transformations that ultimately gave rise to centralized political systems. Political activity was undoubtedly an important element of social interaction, but it was enmeshed with ritual and other activities, such as mound construction, and formed an embedded part of more encompassing, large-scale ceremonial encounters. More than they were aggrandizers, those who resided at Khonkho were social and ideological mediators. This case suggests that non-state complexity may be far more variable than most current archaeological models propose.En este artículo se discute la complejidad temprana en la cuenca sur del lago Titicaca, en los Andes bolivianos. Se estudia un paisaje regional con formaciones de carácter multicomunal que surgieron durante el Periodo Formativo Tardío (100 a.C.-500 d.C.). Se sugiere que, en esta etapa, el establecimiento de Khonkho Wankane, junto con el de los disembedded centers, es decir, centros con poca población residente, pero a los que llegaban gente en número nutrido para la realización de ceremonias, festines u otras prácticas rituales, tuvo un papel importante en la transformación social que dio origen, por último, a los sistemas políticos centralizados. Sin duda, la actividad política fue un elemento importante de interacción social, pero estuvo involucrada con rituales y otras actividades —tales como la construcción de montículos— que constituyeron una parte primordial de los más influyentes encuentros ceremoniales a gran escala. Más que un conjunto de individuos que deseaban diferenciarse o acumular más poder que los demás (aggrandizers), aquellos que residieron en Khonkho Wankane fueron mediadores sociales e ideológicos. Este caso sugiere que la complejidad no estatal pudo ser mucho más variable de lo que diversos modelos arqueológicos proponen en la actualidad.

Full textAbstract:
PURPOSE: Doppler renal resistive index (RRI) has emerged in the last decade as a useful prognostic indicator for transient (fluid responsive) and persistent acute kidney injury (AKI). The determinants of RRI are largely systemic and recent studies confirm that RRI measurement could also be a useful early marker for sub-clinical AKI and post procedural AKI risk. This study aimed to determine the feasibility of RRI measurement in an Emergency Department (ED) resuscitation room setting using a pointofcare ultrasound system. METHODS: In this prospective single centre study, RRI measurement was attempted in 20 non-consecutive patients (meeting the inclusion criteria) by a single expert sonographer. RRI measurements were evaluated against context specific feasibility criteria and target outcomes. RESULTS: 20 patients (11 male, 9 female) were recruited to the study. Age of patients ranged from 33 years to 91 years (mean 62.3 years). Adequate visualisation of both kidneys was achieved in 60% of patients (n=12). In patients where it was not possible to achieve adequate views of both kidneys (n=8), limiting technical factors were shortness of breath (SOB) (n=6), high BMI (n=2). At least one measurement of RRI was achieved in 70% of patients (n=14). However, in 9 of these patients (64.3%) the Doppler spectral traces achieved were substandard and did not meet the measurement criteria for RRI as specified in the study protocol. In 30% of patients (n=6) no usable spectral trace was achieved and it was not possible to measure RRI. SOB was noted as a technical difficulty in 60% of patients (n=12) including three for whom RRI measurements were achieved. In 9 patients (45%) SOB was recorded as the primary reason for failure to acquire a usable Doppler trace. All criteria for RRI measurements were met in only 3 patients (15%). CONCLUSION: Measurement of RRI was not feasible in patients requiring resuscitation room care using a current point of care ultrasound system. If RRI is to play a useful role in this high priority patient group, adaptation of the available technology is required to mitigate the problem of image blur due to patient breathing movement.

Full textAbstract:
Disaster events have emphasized the importance of healthcare response activities due to the large number of victims. For instance, Hurricane Katrina in New Orleans, in 2005, and the terrorist attacks in New York City and Washington, D.C., on September 11, 2001, left thousands of wounded people. In those disasters, although hospitals had disaster plans established for more than a decade, their plans were not efficient enough to handle the chaos produced by the hurricane and terrorist attacks. Thus, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) suggested collaborative planning among hospitals that provide services to a contiguous geographic area during mass casualty disasters. However, the JCAHO does not specify a methodology to determine which hospitals should be included into these cooperative plans. As a result, the problem of selecting the right hospitals to include in exercises and drills at the county level is a common topic in the current preparedness stages. This study proposes an efficiency index to determine the efficient response of cooperative-networks among hospitals before an occurrence of mass casualty disaster. The index built in this research combines operations research techniques, and the prediction of this index used statistical analysis. The consecutive application of three different techniques: network optimization, data envelopment analysis (DEA), and regression analysis allowed to obtain a regression equation to predict efficiency in predefined hospital networks for mass casualty disasters. In order to apply the proposed methodology for creating an efficiency index, we selected the Orlando area, and we defined three disaster sizes. Then, we designed networks considering two perspectives, hub-hospital and hub-disaster networks. In both optimization network models the objective function pursued to: reduce the travel distance and the emergency department (ED) waiting time in hospitals, increase the number of services offered by hospitals in the network, and offer specialized assistance to children. The hospital network optimization generated information for 75 hospital networks in Orlando. The DEA analyzed these 75 hospital networks, or decision making units (DMU's), to estimate their comparative efficiency. Two DEAs were performed in this study. As an output variable for each DMU, the DEA-1 considered the number of survivors allocated in less than a 40 miles range. As the input variables, the DEA-1 included: (i) The number of beds available in the network; (ii) The number of hospitals available in the network; and (iii) The number of services offered by hospitals in the network. This DEA-1 allowed the assignment of an efficiency value to each of the 75 hospital networks. As output variables for each DMU, the DEA-2 considered the number of survivors allocated in less than a 40 miles range and an index for ED waiting time in the network. The input variables included in DEA-2 are (i) The number of beds available in the network; (ii) The number of hospitals available in the network; and (iii) The number of services offered by hospitals in the network. These DEA allowed the assignment of an efficiency value to each of the 75 hospital networks. This efficiency index should allow emergency planners and hospital managers to assess which hospitals should be associated in a cooperative network in order to transfer survivors. Furthermore, JCAHO could use this index to evaluate the cooperating emergency hospitals* plans. However, DEA is a complex methodology that requires significant data gathering and handling. Thus, we studied whether a simpler regression analysis would substantially yield the same results. DEA-1 can be predicted using two regression analyses, which concluded that the average distances between hospitals and the disaster locations, and the size of the disaster explain the efficiency of the hospital network. DEA-2 can be predicted using three regressions, which included size of the disaster, number of hospitals, average distance, and average ED waiting time, as predictors of hospital network efficiency. The models generated for DEA-1 and DEA-2 had a mean absolute percent error (MAPE) around 10%. Thus, the indexes developed through the regression analysis make easier the estimation of the efficiency in predefined hospital networks, generating suitable predictors of the efficiency as determined by the DEA analysis. In conclusion, network optimization, DEA, and regressions analyses can be combined to create an index of efficiency to measure the performance of predefined-hospital networks in a mass casualty disaster, validating the hypothesis of this research. Although the methodology can be applied to any county or city, the regressions proposed for predicting the efficiency of hospital network estimated by DEA can be applied only if the city studied has the same characteristics of the Orlando area. These conditions include the following: (i) networks must have a rate of services lager than 0.76; (ii) the number of survivors must be less than 47% of the bed capacity EDs of the area studied; (iii) all hospitals in the network must have ED and they must be located in less than 48 miles range from the disaster sites, and (iv) EDs should not have more than 60 minutes of waiting time. The proposed methodology, in special the efficiency index, support the operational objectives of the 2012 ESF#8 for Florida State to handle risk and response capabilities conducting and participating in training and exercises to test and improve plans and procedures in the health response.Ph.D.

Los bonos elegidos han sido los Bradies, debido aque sus características institucionales son similares para distintos emisores. La metodologíapropuesta toma elementos de los modelos tradicionales, como la estructurafuncional de la probabilidad de impago y de los modelos de estructura de términos. Enresumen, este trabajo presenta una nueva manera de extraer el riesgo soberano quese encuentra implícito en los precios de los bonos elegidos en el mercado secundario.

Full textAbstract:
Although in the debate over the current financial crisis there is a general agreement on the role played by foreign capital inflows into the United States —that, together with financial deregulation, allowed for an excessive increase of credit in that country—, we think that their importance has not been fully appreciated, in terms of their link with the asymmetrical organization of an international monetary system that uses the dollar as a reserve currency, and their relationship with the economic growth model adopted by the US over the last thirty years; this relied on increased expenditure on the part of credit-financed households in order to maintain its dynamism, while inflation was kept down by importing cheap foreign manufactures at the expense of the domestic sector’s profitability. We suggest here that the crisis was related to the impossibility of maintaining this economic growth pattern indefinitely, and that recovery will require a radical reform of the international monetary system, as well as a general increase in economic efficiency.Aunque en el debate sobre la actual crisis financiera se ha reconocido el rol jugado por el influjo de capitales extranjeros hacia Estados Unidos —el cual, conjuntamente con la desregulación financiera, hizo posible el crecimiento desmedido del crédito en ese país—, pensamos que aún no se ha reconocido la importancia de tal influjo, ni su conexión con la forma asimétrica como está organizado el actual sistema monetario internacional, ni tampoco su relación con el tipo de crecimiento adoptado por ese país en las últimas tres décadas, que pudo mantener su dinamismo gracias al aumento del gasto de los hogares financiado con crédito, y que mantuvo baja la inflación gracias a la importación de manufacturas baratas, al costo de ver caer la rentabilidad de su sector manufacturero. Sugerimos aquí que la crisis surge por la imposibilidad de llevar adelante ese tipo de crecimiento de manera indefinida y sin sobresaltos, y que una recuperación requerirá tanto una reforma radical del sistema monetario, como el aumento de la eficiencia económica a nivel mundial.

Full textAbstract:
This research focuses on the comprehension of the metropolitan rurality of the Aburrá valley (Department of Antioquia-Colombia) to identify and define its more significant characteristics from the process analysis of territorial management and the transformations that appear in the territory in relation to them. One research premise is given by the planning and territorial managemente processes initiated in the 1990s which have insisted in the urban-rural dynamics and have contributed to the appearance of transformations at the pheripheres of the urban nucleus of the Aburrá valley and, therefore, in the contiguous rural hinterlands.These processes have limited the vision and definition of the rural metropolitan territory as opposed to the urban. It is possible to understand what is going on in these territories, what changes are ocurrying in their natural composition and at their economic and productive dynamics, and what is the relationship of these changes with the territorial mangement process.The case study is based on three places of the metropolitan area of the Aburrá valley, that represent the recognized territories with characteristics more appropiated to the rurality and that allow to make comparisons of the transformation processes underway and that area object of analysis in the research: to North the municpality of Barbosa, to South, the municipality of Caldas, and to the centre the «corregimiento» of San Sebastian de Palmitas in Medellin.La investigación está centrada en la comprensión de la ruralidad metropolitana del valle de Aburrá (departamento de Antioquia – Colombia) para identificar y definir sus características más significativas a partir del análisis de los procesos de ordenamiento territorial y de las transformaciones que se presentan en el territorio relacionadas con los mismos.Una premisa de investigación está dada por los procesos planificación y ordenamiento territorial iniciados a finales de la década de 1990 que han incidido en las dinámicas urbano-rurales y han contribuido a la generación de transformaciones en las periferias de los núcleos urbanos del valle de Aburrá y, por consiguiente, en los entornos rurales inmediatos. Estos procesos han limitado la visión y definición del territorio rural metropolitano a su contraposición con lo urbano. Se pretende esclarecer qué está ocurriendo en estos territorios, qué cambios se están dando en su composición natural y en sus dinámicas económicas y productivas y cuál es la relación de estos cambios con los procesos de ordenamiento territorial. Como caso de estudio se eligen tres lugares del área metropolitana del valle de Aburrá: al norte el municipio de Barbosa; al sur, el municipio de Caldas; y en el centro el corregimiento de San Sebastián de Palmitas en Medellín. El proceso de recorridos de campo y realización de entrevistas ha permitido identificar diferencias importantes en los tres territorios analizados, a pesar de pertenecer al mismo contexto metropolitano. Se logran identificar tendencias mayores de transformación en los extremos del valle (Barbosa y Caldas) mientras que en el centro se encuentra un enclave rural con transformaciones dadas pero que conserva aún muchas de sus características de ruralidad tradicional identificables en los modos de producción y en las expectativas y sentires de la población. Estos hallazgos empiezan a dar cuenta de unas gradaciones de ruralidad, un relacionamiento diferenciado con el territorio e impactos particulares de los procesos de ordenamiento territorialen las tres zonas.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIROHistoricamente, observa-se que as volatilidades de variáveis financeiras são drasticamente afetadas em períodos de crises econômicas. Em particular, essa observação é válida para a taxa de câmbio entre o Real e o Dólar norte-americano, o Índice Bovespa e o EMBI Brasil (Emerging Market Bond Índex+Brazil), usualmente utilizado como medida de Risco-País para a economia brasileira. Diante de tais evidências empíricas, a existência de um fator comum entre as volatilidades das três variáveis citadas torna-se uma suposição plausível. O presente trabalho propõe a extração deste fator latente, através da estimação por Quasi Máxima Verossimilhança de uma adaptação do modelo de volatilidade estocástica. A estimação é feita através da aplicação do filtro de Kalman em sua versão difusa, uma vez que se supõe que as volatilidades das variáveis em questão seguem processos não estacionários. A conclusão do trabalho apontou para a existência de um único fator comum às volatilidades mencionadas, corroborando as expectativas preliminares.
Historically, financial variables’ volatilities are drastically affected during economical crisis periods. In particular, this statement is valid for the exchange rate between brazilian and north american currencies, the São Paulo Stock Exchange Index (Ibovespa) and the Emerging Market Bond Index + Brazil, usually interpreted as a measure of brazilian sovereign risk. Therefore, the presence of a common factor affecting the volatilities of these three variables becomes a plausible assumption. This work intends to extract this latent factor applying the quasi-maximum likelihood estimator into an adapted stochastic volatility model. The estimation requires the Kalman filtering on its diffuse version, once it’s supposed that the volatilities follow a non stationary process. The results indicated the presence of one common factor driving the mentioned volatilities, confirming the previous expectations.

Full textAbstract:
La presente investigación se encuadra dentro de la historia popular que busca destacar el proceso histórico del neo-populismo liderizado por el destacado comunicador popular Carlos Palenque Avilés en la ciudad metrópoli de La Paz a fines de siglo XX en el transcurso de la historia política boliviana, que llegó a poner en cuestionamiento a un Estado neoliberal e indiferente que no representaba las demandas de los sectores marginados y desclazados de la sociedad, debido a ello el nombre de la tesis: “CONDEPA: LA EMERGENCIA DEL NEOPOPULISMO A FINES DEL SIGLO XX EN LA CIUDAD DE LA PAZ”. Por consiguiente el condepismo o la “Emergencia del Neopopulismo”, fue la respuesta a la crisis nacional del Estado en los años 80 luego del periodo dictatorial, cuando el país nuevamente reclamaba una alternativa de solución a los problemas de los sectores más postergados de la sociedad. Este hecho provocó cambios en cuanto a participación popular de la plebe urbana, resultado de una emergencia social, y el surgimiento de CONDEPA en la escena política apoyado y moldeado por las masas populares, que rompió todos los esquemas tradicionales de organización partidaria, para abrir una nueva perspectiva de participación de las mayorías discriminadas luego de la revolución del 52. A partir de ese momento el partido de extracción popular tuvo el gran desafío de luchar por alcanzar una nueva visión de Estado con el modelo endógeno de desarrollo que pregonó: la revolución productiva, la revolución moral y la democracia participativa, como premisas fundamentales del proyecto político, que se manifestó de diversas maneras tanto de hecho como de derecho en una movilización permanente en contra de los gobiernos neoliberales que no vacilaron en enajenar los recursos naturales con el uso de leyes anticonstitucionales en desmedro del pueblo. Estos aspectos son los que caracterizan el neopopulismo a fines de siglo XX en Bolivia, que continuará en pleno siglo XXI, porque mientras no se erradique la pobreza y el hambre, no existan medidas económicas acertadas y no se abran espacios de participación social en niveles decisorios del Estado, el populismo se seguirá fortaleciendo, no interesando quién sea el líder, mientras éste tenga carisma y se identifique con los más necesitados, tendrá plena repercusión en la vida social boliviana.
