A comparative analysis of CHIP Perinatal policy in twelve states

The purpose of this comparative analysis of CHIP Perinatal policy (42 CFR § 457) was to provide a basis for understanding the variation in policy outputs across the twelve states that, as of June 2007, implemented the Unborn Child rule. This Department of Health and Human Services regulation expanded in 2002 the definition of “child” to include the period from conception to birth, allowing states to consider an unborn child a “targeted low-income child” and therefore eligible for SCHIP coverage. ^ Specific study aims were to (1) describe typologically the structural and contextual features of the twelve states that adopted a CHIP Perinatal policy; (2) describe and differentiate among the various designs of CHIP Perinatal policy implemented in the states; and (3) develop a conceptual model that links the structural and contextual features of the adopting states to differences in the forms the policy assumed, once it was implemented. ^ Secondary data were collected from publicly available information sources to describe characteristics of states’ political system, health system, economic system, sociodemographic context and implemented policy attributes. I posited that socio-demographic differences, political system differences and health system differences would directly account for the observed differences in policy output among the states. ^ Exploratory data analysis techniques, which included median polishing and multidimensional scaling, were employed to identify compelling patterns in the data. Scaled results across model components showed that economic system was most closely related to policy output, followed by health system. Political system and socio-demographic characteristics were shown to be weakly associated with policy output. Goodness-of-fit measures for MDS solutions implemented across states and model components, in one- and two-dimensions, were very good. ^ This comparative policy analysis of twelve states that adopted and implemented HHS Regulation 42 C.F.R. § 457 contributes to existing knowledge in three areas: CHIP Perinatal policy, public health policy and policy sciences. First, the framework allows for the identification of CHIP Perinatal program design possibilities and provides a basis for future studies that evaluate policy impact or performance. Second, studies of policy determinants are not well represented in the health policy literature. Thus, this study contributes to the development of the literature in public health policy. Finally, the conceptual framework for policy determinants developed in this study suggests new ways for policy makers and practitioners to frame policy arguments, encouraging policy change or reform. ^

A promotora de salud CVD intervention: Participant responses after Su Corazon, Su Vida education

In this study we sought to identify and understand feelings, benefits and barriers to making heart healthy behavioral changes by reviewing and analyzing participant responses to a follow-up telephone survey conducted as part of the HEART project (Health Education Awareness Research Team). Individuals who participated in HEART attended classes and received “Su Corazon, Su Vida” education. The HEART follow-up telephone survey was conducted only on those participants who were part of the experimental group. A total of 93 individuals from this group were successfully contacted for participation in the telephone survey after the classes ended. Quantitative data regarding ‘feelings’ and ‘difficulty making heart healthy behavioral changes’ were analyzed by calculating frequencies of each category of response for post-intervention weeks 9, 13, and 15. In addition, Wilcoxon rank-sum tests were conducted for post-intervention at weeks 9, 13, and 15 to measure associations between feelings and difficulties making heart healthy behavioral changes. Changes in responses over time for feelings and difficulties making heart healthy behavioral changes were looked at by counting differences in responses between pairs of follow up weeks. Qualitative responses to the survey were analyzed by categorizing content of responses under themes in order to identify factors related to feelings and difficulties making heart healthy behavioral changes. Telephone survey participants showed positive attitudes towards making nutritional and physical activity changes. Out of the 93 telephone survey respondents, 53 (57%) reported some type of physical activity change during the follow-up period while 46 (49%) reported specific changes in nutrition. Data from the “difficulty to making changes” responses were categorized under constructs from the Health Belief Model, perceived benefits and barriers. Overall, the barriers for physical activity were health issues, individual habits and time. Barriers to eating healthy were family support, individual habits, and knowledge. This study suggests that with respect to nutritional knowledge barriers, educational programs should explore other ways of teaching and familiarizing individuals with information sources that may be more appropriate for those populations not accustomed to them. For example, nutrition labels, portions, recipes, and use of photonovelas. Our findings of the barriers to changes in food preparation due to lack of family support may also suggest the need for the development of programs where influential partners or relatives are involved in order to create a more supportive environment which may provide more opportunity for change toward healthier lifestyle behaviors. Finally, the physical activity barriers found suggest that it may be beneficial to recommend appropriate exercises for those with specific health problems or those with time restrictions due to work or travel so that physical activity is not completely avoided.^

Patterns of homicide Houston: Texas, 1987

The situational and interpersonal characteristics of homicides occurring in Houston, Texas, during 1987 were investigated. A total of 328 cases were ascertained from the linking of police computer data, medical examiner's records, and death certificate information. The medical examiner's records contained all of the ascertained cases. The comparability ratio between the medical examiner's records and police and vital statistic data was 1.03 and 0.966, respectively. Data inconsistencies were found between the three information sources on Spanish surname, age, race/ethnicity, external cause of death coding, alcohol and drug involvement, weapon/method used, and Hispanic immigration status. Recommendations for improving the quality of homicide information gathered and for linking homicide surveillance systems were made.^ Males constituted 82% of all victims. The age-adjusted homicide rate for Blacks was 31.1 per 100,000 population, for Hispanics 19.2, and for Anglos 5.4. Among males, Blacks had an age-adjusted rate of 54.5, Hispanics, 31.0, and Anglos 7.5. Among females, Blacks had an age-adjusted rate of 9.3, Hispanics 6.1, and Anglos 3.1. Black males, ages 25-34, had the highest homicide rate, at 96.5.^ Half of all homicides occurred in a residence. Among Hispanic males, homicides occurred most often in the street. Firearms were used to commit 64% of the homicides. Arguments preceded 58% of all cases. Nearly two-thirds of the victims knew their assailant. Only 15% of males compared to 62% of females were killed by a spouse, an intimate acquaintance, or a family member. Blacks (93%) and Hispanics (88%) were more likely than Anglos (70%) to have been killed by persons of the same race/ethnicity. Nearly three-fourths of all Houston Hispanic homicide victims were foreign born.^ Alcohol was detected in 47% of the victims tested. Nearly one-third of those tested had blood alcohol concentrations (BACs) greater than 100 mg%. Males (53%) were more likely than females (20%) to have positive BACs. Hispanic males (64%) were more likely to have detectable BACs than either Black (51%) or Anglo (44%) males.^ Illegal drugs were detected in 20% of the victims tested. One-fourth of the victims who tested positive for drugs had more than one drug in their system at death. The stimulant cocaine was the most commonly detected drug, comprising 53% of all illegal drugs identified.^ Recommendations for the primary, secondary, and tertiary prevention of homicide and for future homicide research are made. ^

Comparison and Assessment of Two Emission inventories for the Madrid Region

Emission inventories are databases that aim to describe the polluting activities that occur across a certain geographic domain. According to the spatial scale, the availability of information will vary as well as the applied assumptions, which will strongly influence its quality, accuracy and representativeness. This study compared and contrasted two emission inventories describing the Greater Madrid Region (GMR) under an air quality simulation approach. The chosen inventories were the National Emissions Inventory (NEI) and the Regional Emissions Inventory of the Greater Madrid Region (REI). Both of them were used to feed air quality simulations with the CMAQ modelling system, and the results were compared with observations from the air quality monitoring network in the modelled domain. Through the application of statistical tools, the analysis of emissions at cell level and cell – expansion procedures, it was observed that the National Inventory showed better results for describing on – road traffic activities and agriculture, SNAP07 and SNAP10. The accurate description of activities, the good characterization of the vehicle fleet and the correct use of traffic emission factors were the main causes of such a good correlation. On the other hand, the Regional Inventory showed better descriptions for non – industrial combustion (SNAP02) and industrial activities (SNAP03). It incorporated realistic emission factors, a reasonable fuel mix and it drew upon local information sources to describe these activities, while NEI relied on surrogation and national datasets which leaded to a poorer representation. Off – road transportation (SNAP08) was similarly described by both inventories, while the rest of the SNAP activities showed a marginal contribution to the overall emissions.

Desarrollo de una GUI para el estudio de Sistemas de Comunicaciones Ópticas

El peso específico de las Comunicaciones Ópticas dentro del ámbito de la Ingeniería de Telecomunicación no cesa de crecer. Sus aplicaciones, inicialmente dedicadas a las grandes líneas que enlazan las centrales de conmutación, alcanzan en la actualidad, como se ha mencionado, hasta los mismos hogares. Los progresos en este campo, con una sucesión sin tregua, no sólo se destinan a incrementar la capacidad de transmisión de los sistemas, sino a ampliar la diversidad de los procesos que sobre las señales se efectúan en el dominio óptico. Este dinamismo demanda a los profesionales del sector una revisión y actualización de sus conocimientos que les permitan resolver con soltura las cuestiones de su actividad de ingeniería. Por otra parte, durante los últimos años la importancia de las Comunicaciones Ópticas también se ha reflejado en las diferentes titulaciones de Ingenierías de Telecomunicación, cuyos planes de estudio contemplan esta materia tanto en asignaturas troncales como optativas. A menudo, las fuentes de información disponibles abordan esta disciplina con una orientación principalmente teórica. Profesionales y estudiantes de Ingeniería, pues, frente a esta materia se encuentran unos temas que tratan fenómenos físicos complejos, abundantes en conceptos abstractos y con un florido aparato matemático, pero muchas veces carentes de una visión práctica, importantísima en ingeniería, y que es, en definitiva, lo que se exige a alumnos e ingenieros: saber resolver problemas y cuestiones relacionados con las Comunicaciones Ópticas. Los sistemas de comunicaciones ópticas, y en especial aquellos que utilizan la fibra óptica como medio para la transmisión de información, como se ha dicho, están alcanzando un desarrollo importante en el campo de las telecomunicaciones. Las bondades que ofrece la fibra, de sobra conocidos y mencionados en el apartado que antecede (gran ancho de banda, inmunidad total a las perturbaciones de origen electromagnético, así como la no producción de interferencias, baja atenuación, etc.), han hecho que, hoy en día, sea uno de los campos de las llamadas tecnologías de la información y la comunicación que presente mayor interés por parte de científicos, ingenieros, operadores de telecomunicaciones y, por supuesto, usuarios. Ante esta realidad, el objetivo y justificación de la realización de este proyecto, por tanto, no es otro que el de acercar esta tecnología al futuro ingeniero de telecomunicaciones, y/o a cualquier persona con un mínimo de interés en este tema, y mostrarle de una forma práctica y visual los diferentes fenómenos que tienen lugar en la transmisión de información por medio de fibra óptica, así como los diferentes bloques y dispositivos en que se divide dicha comunicación. Para conseguir tal objetivo, el proyecto fin de carrera aquí presentado tiene como misión el desarrollo de una interfaz gráfica de usuario (GUI, del inglés Graphic User Interface) que permita a aquel que la utilice configurar de manera sencilla cada uno de los bloques en que se compone un enlace punto a punto de fibra óptica. Cada bloque en que se divide este enlace estará compuesto por varias opciones, que al elegir y configurar como se quiera, hará variar el comportamiento del sistema y presentará al usuario los diferentes fenómenos presentes en un sistema de comunicaciones ópticas, como son el ruido, la dispersión, la atenuación, etc., para una mejor comprensión e interiorización de la teoría estudiada. Por tanto, la aplicación, implementada en MATLAB, fruto de la realización de este PFC pretende servir de complemento práctico para las asignaturas dedicadas al estudio de las comunicaciones ópticas a estudiantes en un entorno amigable e intuitivo. Optical Communications in the field of Telecommunications Engineering continues to grow. Its applications, initially dedicated to large central lines that link the switching currently achieved, as mentioned, to the same household nowadays. Progress in this field, with a relentless succession, not only destined to increase the transmission capacity of the systems, but to broaden the diversity of the processes that are performed on the signals in the optical domain. This demands to professionals reviewing and updating their skills to enable them resolve issues easily. Moreover, in recent years the importance of optical communications is also reflected in the different degrees of Telecommunications Engineering, whose curriculum contemplates this area. Often, the information sources available to tackle this discipline mainly theoretical orientation. Engineering professionals and students are faced this matter are few topics discussing complex physical phenomena, and abstract concepts abundant with a flowery mathematical apparatus, but often wotput a practical, important in engineering, and that is what is required of students and engineers: knowing how to solve problems and issues related to optical communications. Optical communications systems, particularly those using optical fiber as a medium for transmission of information, as stated, are reaching a significant development in the field of telecommunications. The advantages offered by the fiber, well known and referred to in the preceding paragraph (high bandwidth, immunity to electromagnetic disturbances of origin and production of non interference, low attenuation, etc..), have made today, is one of the fields of information and communication technology that this increased interest by scientists, engineers, telecommunications operators and, of course, users. Given this reality, the purpose and justification of this project is not other than to bring this technology to the future telecommunications engineer, and / or anyone with a passing interest in this subject, and showing of a practical and various visual phenomena occurring in the transmission of information by optical fiber, as well as different blocks and devices in which said communication is divided. To achieve that objective, the final project presented here has as its mission the development of a graphical user interface (GUI) that allows the user to configure each of the blocks in which divided a point-to-point optical fiber. Each block into which this link will consist of several options to choose and configure it as you like, this will change the behavior of the system and will present to the user with the different phenomena occurring in an optical communication system, such as noise, dispersion, attenuation, etc., for better understanding and internalization of the theory studied. Therefore, the application, implemented in MATLAB, the result of the completion of the thesis is intended to complement practical subjects for the study of optical communications students in a friendly and intuitive environment.

GreenDisc: a HW/SW energy optimization framework in globally distributed computation

In recent future, wireless sensor networks (WSNs) will experience a broad high-scale deployment (millions of nodes in the national area) with multiple information sources per node, and with very specific requirements for signal processing. In parallel, the broad range deployment of WSNs facilitates the definition and execution of ambitious studies, with a large input data set and high computational complexity. These computation resources, very often heterogeneous and driven on-demand, can only be satisfied by high-performance Data Centers (DCs). The high economical and environmental impact of the energy consumption in DCs requires aggressive energy optimization policies. These policies have been already detected but not successfully proposed. In this context, this paper shows the following on-going research lines and obtained results. In the field of WSNs: energy optimization in the processing nodes from different abstraction levels, including reconfigurable application specific architectures, efficient customization of the memory hierarchy, energy-aware management of the wireless interface, and design automation for signal processing applications. In the field of DCs: energy-optimal workload assignment policies in heterogeneous DCs, resource management policies with energy consciousness, and efficient cooling mechanisms that will cooperate in the minimization of the electricity bill of the DCs that process the data provided by the WSNs.

Integración de Fuentes con Información de Contexto y Sistemas Interactivos

Durante el transcurso de esta Tesis Doctoral se ha realizado un estudio de la problemática asociada al desarrollo de sistemas de interacción hombre-máquina sensibles al contexto. Este problema se enmarca dentro de dos áreas de investigación: los sistemas interactivos y las fuentes de información contextual. Tradicionalmente la integración entre ambos campos se desarrollaba a través de soluciones verticales específicas, que abstraen a los sistemas interactivos de conocer los procedimientos de bajo nivel de acceso a la información contextual, pero limitan su interoperabilidad con otras aplicaciones y fuentes de información. Para solventar esta limitación se hace imprescindible potenciar soluciones interoperables que permitan acceder a la información del mundo real a través de procedimientos homogéneos. Esta problemática coincide perfectamente con los escenarios de \Computación Ubicua" e \Internet de las Cosas", donde se apunta a un futuro en el que los objetos que nos rodean serán capaces de obtener información del entorno y comunicarla a otros objetos y personas. Los sistemas interactivos, al ser capaces de obtener información de su entorno a través de la interacción con el usuario, pueden tomar un papel especial en este escenario tanto como consumidores como productores de información. En esta Tesis se ha abordado la integración de ambos campos teniendo en cuenta este escenario tecnológico. Para ello, en primer lugar se ha realizado un an álisis de las iniciativas más importantes para la definición y diseño de sistemas interactivos, y de las principales infraestructuras de suministro de información. Mediante este estudio se ha propuesto utilizar el lenguaje SCXML del W3C para el diseño de los sistemas interactivos y el procesamiento de los datos proporcionados por fuentes de contexto. Así, se ha reflejado cómo las capacidades del lenguaje SCXML para combinar información de diferentes modalidades pueden también utilizarse para procesar e integrar información contextual de diferentes fuentes heterogéneas, y por consiguiente diseñar sistemas de interacción sensibles al contexto. Del mismo modo se presenta a la iniciativa Sensor Web, y a su extensión semántica Semantic Sensor Web, como una iniciativa idónea para permitir un acceso y suministro homogéneo de la información a los sistemas interactivos sensibles al contexto. Posteriormente se han analizado los retos que plantea la integración de ambos tipos de iniciativas. Como resultado se ha conseguido establecer una serie de funcionalidades que son necesarias implementar para llevar a cabo esta integración. Utilizando tecnologías que aportan una gran flexibilidad al proceso de implementación y que se apoyan en recomendaciones y estándares actuales, se implementaron una serie de desarrollos experimentales que integraban las funcionalidades identificadas anteriormente. Finalmente, con el fin de validar nuestra propuesta, se realizaron un conjunto de experimentos sobre un entorno de experimentación que simula el escenario de la conducción. En este escenario un sistema interactivo se comunica con una extensión semántica de una plataforma basada en los estándares de la Sensor Web para poder obtener información y publicar las observaciones que el usuario realizaba al sistema. Los resultados obtenidos han demostrado la viabilidad de utilizar el lenguaje SCXML para el diseño de sistemas interactivos sensibles al contexto que requieren acceder a plataformas avanzadas de información para consumir y publicar información a la vez que interaccionan con el usuario. Del mismo modo, se ha demostrado cómo la utilización de tecnologías semánticas en los procesos de consulta y publicación de información puede facilitar la reutilización de la información publicada en infraestructuras Sensor Web por cualquier tipo de aplicación, y de este modo contribuir al futuro escenario de Internet de las Cosas. ABSTRACT In this Thesis, we have addressed the difficulties related to the development of context-aware human-machine interaction systems. This issue is part of two research fields: interactive systems and contextual information sources. Traditionally both fields have been integrated through domain-specific vertical solutions that allow interactive systems to access contextual information without having to deal with low-level procedures, but restricting their interoperability with other applications and heterogeneous data sources. Thus, it is essential to boost the research on interoperable solutions that provide access to real world information through homogeneous procedures. This issue perfectly matches with the scenarios of \Ubiquitous Computing" and \Internet of Things", which point toward a future in which many objects around us will be able to acquire meaningful information about the environment and communicate it to other objects and to people. Since interactive systems are able to get information from their environment through interaction with the user, they can play an important role in this scenario as they can both consume real-world data and produce enriched information. This Thesis deals with the integration of both fields considering this technological scenario. In order to do this, we first carried out an analysis of the most important initiatives for the definition and design of interactive systems, and the main infrastructures for providing information. Through this study the use of the W3C SCXML language is proposed for both the design of interactive systems and the processing of data provided by different context sources. Thus, this work has shown how the SCXML capabilities for combining information from different modalities can also be used to process and integrate contextual information from different heterogeneous sensor sources, and therefore to develope context-aware interaction systems. Similarly, we present the Sensor Web initiative, and its semantic extension Semantic Sensor Web, as an appropriate initiative to allow uniform access and delivery of information to the context-aware interactive systems. Subsequently we have analyzed the challenges of integrating both types of initiatives: SCXML and (Semantic) Sensor Web. As a result, we state a number of functionalities that are necessary to implement in order to perform this integration. By using technologies that provide exibility to the implementation process and are based on current recommendations and standards, we implemented a series of experimental developments that integrate the identified functionalities. Finally, in order to validate our approach, we conducted different experiments with a testing environment simulating a driving scenario. In this framework an interactive system can access a semantic extension of a Telco plataform, based on the standards of the Sensor Web, to acquire contextual information and publish observations that the user performed to the system. The results showed the feasibility of using the SCXML language for designing context-aware interactive systems that require access to advanced sensor platforms for consuming and publishing information while interacting with the user. In the same way, it was shown how the use of semantic technologies in the processes of querying and publication sensor data can assist in reusing and sharing the information published by any application in Sensor Web infrastructures, and thus contribute to realize the future scenario of \Internet of Things".

Desarrollo de una metodología de vigilancia tecnológica para la toma de decisiones : aplicación a las tecnologías multimedia

La aplicación de la vigilancia tecnología se ha mostrado como una de las herramientas más importantes para ganar competitividad y mejorar las actividades de innovación de las empresas. La vigilancia se basa en captar las informaciones, normalmente patentes y publicaciones científicas, más relevantes para un determinado campo tecnológico y valorarlas para influir en la toma de decisiones. Las fases clásicas son: búsqueda, análisis y comunicación de la información. El trabajo se soportará tanto en herramientas comerciales como en otras que deberá desarrollar el estudiante, y tendrá como objetivo fundamental el desarrollar una metodología, basada en la vigilancia, para tomar decisiones sobre tecnologías y en este caso aplicadas a las tecnologías multimedia. El objetivo principal en la propuesta de una metodología genérica de vigilancia tecnológica (VT/IC) para la toma de decisiones con un ejemplo de aplicación en las tecnologías multimedia y que más adelante se explicitó en TV 3D. La necesidad de que el proceso de VT/IC se soporte en una metodología es imprescindible si queremos darle la importancia que debe tener en el ciclo productivo de cualquier tipo de organización y muy especialmente en una organización involucrada en investigación y desarrollo (I+D+i). Esta metodología posibilitará, entre otras cosas, que estos procesos que conforman la VT/IC puedan integrarse en una organización compartiendo los procesos productivos, de administración y de dirección de la organización. Permitirá una medición de su funcionamiento y las posibles modificaciones para obtener un mejor funcionamiento. Proveerá a los posibles elementos involucrados en la VT/IC de la documentación, procesos, herramientas, elementos de medición de un sistema definido, publicado, medido y analizado de trabajo. Finalmente a modo de ejemplo de un proceso de consulta VT/IC utilizaremos el criterio de búsqueda genérico 3D TV propuesto. Estructura del PFC: Para lograr estos objetivos el trabajo ha sido dividido en 6 etapas: 1.- Descripción del PFC: Una presentación del PFC y su desarrollo. 2.- Vigilancia tecnológica: Desarrollo del concepto de VT/IC, los efectos esperados, beneficios y riesgos de la VT/IC, concepto de inteligencia competitiva (IC), concepto aplicado de vigilancia tecnológica e inteligencia competitiva (VT/IC). 3.- Técnicas de análisis empresarial donde la VT/IC es útil: para empezar a entender como debe ser la VT/IC analizamos como una organización utiliza las distintas técnicas de análisis y que información aportan cada una de ellas, finalmente analizamos como la VT/IC ayuda a esas técnicas de análisis. 4.- Gestión de las fuentes de información: análisis de los tipos de fuentes de información y sus herramientas de búsqueda asociadas. 5.- Metodología propuesta de la VT/IC: desarrollo de la metodología de implementación y de funcionamiento de una unidad de VT/IC. 6.- Observatorio: a modo de ejemplo, “3d TV”. ABSTRACT. The application of surveillance technology has proven to be one of the most important to increase competitiveness and improve the innovation activities of enterprises tools. Surveillance is based on capturing the information, usually patents and scientific publications most relevant to a given technological field and assess them to influence decision making. The classical phases are: search, analysis and communication of information. The work will support both commercial and other tools to be developed by the student, and will have as main objective to develop a methodology, based on monitoring to make decisions about technologies and in this case applied to multimedia technologies. The main objective in the proposed generic methodology for technological awareness (VT / IC) for decision making with an example application in multimedia technologies and later made explicit 3D TV. The need for the process of VT / CI support methodology is essential if we give it the importance it should have in the production cycle of any organization and especially in an organization involved in research and development (R + D + i). This methodology will allow, among other things, that these processes that make up the VT / IC can be integrated into an organization sharing production processes, management and direction of the organization. It will allow a measurement of its performance and possible changes for better performance. It will provide the possible elements involved in the VT / IC documentation, processes, tools, measuring elements of a defined system, published, measured and analyzed work. Finally an example of a consultation process VT / IC use generic search criteria proposed 3D TV. Structure of the PFC: To achieve these objectives the work has been divided into 6 stages: 1. PFC Description: A presentation of the PFC and its development. 2. Technology Watch: Concept Development of VT / IC, expected effects, benefits and risks of VT / IC concept of competitive intelligence (CI) concept applied technology watch and competitive intelligence (VT / IC). 3.
